Hot-pressing member with improved focus of pressing and longevity and hot-pressing device
A hot-pressing member proofed against thinning and shearing forces caused by laterally overflowing during pressing operations includes a base with cavity, a first supporting member in the cavity, a buffer member, and a second supporting member. The first supporting member includes first through hole. The buffer member includes a second through hole. The second supporting member is mounted on the buffer member. The second supporting member with third through hole supports the workpiece. The workpiece or part is in the third, second, and first through holes, and is hot-pressed with the adhesive film in a centered and constrained manner through all the through holes. The disclosure also provides a hot-pressing device having the hot-pressing member.

3. The hot-pressing member of claim 1 , wherein a side wall of the buffer member is connected to ends of the first inner wall and the second inner wall away from the bottom wall.
4. The hot-pressing member of claim 1 , wherein a ratio of a depth of the concave portion with respect to a height of the buffer member protruding from the concave portion is 60% to 80%.
5. The hot-pressing member of claim 1 , wherein an inclined angle of each of the first inner wall and the second inner wall is 10 degrees to 80 degrees.
6. The hot-pressing member of claim 1 , further comprising a cover plate, wherein the cover plate is mounted on the second supporting member, the cover plate comprises a fourth through hole, the fourth through hole and the third through hole are coaxial, an inner diameter of the fourth through hole is greater than an inner diameter of the third through hole.
7. The hot-pressing member of claim 1 , wherein the first supporting member comprises an outer wall, a portion of the outer wall comprises a groove, a convex plate is disposed on an inner wall of the cavity, and the convex plate is disposed in the groove.
8. The hot-pressing member of claim 1 , wherein the buffer member is made of a silicone rubber.
