the slide portion is connected to the connecting rod, the guide portion is movably connected to the pedestal, and the guide portion is able to move relative to the pedestal along a first direction so that, when the slide portion is located in the first position, a length direction of the connecting rod is parallel to the first direction, the hold-down bar is in abutment with the end plate along a second direction, and the first direction intersects the second direction, and so that, when the slide portion is located in the second position, the length direction of the connecting rod is at a preset angle to the first direction.

3. The end plate positioning apparatus according to claim 1 , wherein the guide portion comprises a guide slot, the slide portion comprises a bulge extending into the guide slot, and the bulge is slidably connected to the guide slot.

4. The end plate positioning apparatus according to claim 3 , wherein the guide slot comprises at least a first hole and a second hole that communicate with each other, and a connecting line of an axis of the first hole and an axis of the second hole is at a preset angle to the first direction; and

the length direction of the connecting rod is parallel to the first direction when the bulge is located in the first hole, and the length direction of the connecting rod is at the preset angle to the first direction when the bulge slides to the second hole.

5. The end plate positioning apparatus according to claim 4 , wherein the first hole and the second hole are through-holes, or, the first hole and the second hole are blind holes.

6. The end plate positioning apparatus according to claim 2 , wherein the positioning locking piece further comprises a first driving portion, and the first driving portion is connected to the pedestal and is configured to drive the guide portion to move along the first direction.

7. The end plate positioning apparatus according to claim 1 , wherein the end plate positioning apparatus further comprises a second positioning mechanism, and the second positioning mechanism comprises:

a suction cup, movably connected to a side of the pedestal toward the end plate, wherein the suction cup contains a suction end face configured to attract the end plate; and

a second driving portion, connected to the pedestal, and configured to drive the suction cup to draw the end plate to approach or move away from the pedestal.

8. The end plate positioning apparatus according to claim 7 , wherein the pedestal contains a first sidewall, the supporting piece is detachably connected to the first sidewall, an abutting piece is disposed above the supporting piece on the first sidewall, and the end plate is in contact and fit with the abutting piece when the suction cup draws the end plate to approach the pedestal.

9. The end plate positioning apparatus according to claim 2 , wherein the end plate positioning apparatus further comprises a third positioning mechanism, the third positioning mechanism is able to move relative to the pedestal along the first direction, and the third positioning mechanism comprises:

a mounting portion, movably connected to the pedestal so that the mounting portion is able to move along the first direction;

clamping portions, movably connected to the mounting portion, and symmetrically arranged along a third direction; and

a third driving portion, connected to the mounting portion, and configured to drive the symmetrically arranged clamping portions to approach each other or move away from each other along the third direction, wherein the third direction intersects the first direction.

10. The end plate positioning apparatus according to claim 9 , wherein the mounting portion possesses an alignment center line, and the alignment center line is located in a middle position between the two clamping portions along the third direction.
