[0055] The following specific embodiments are exemplary and non-limiting, and are intended to provide a basic understanding of the present application, and are not intended to identify the key or decisive elements of the present application or to limit the scope of protection. As long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.

[0056] When a component is considered to be “provided on” another component, it can be directly provided on the other component or there may be a component in between. When a component is considered to be “connected to” another component, it can be directly connected to the other component or there may be a component in between.

[0057] It can be understood that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular or equal to each other between the two components. For example, in combination with numerical descriptions, perpendicularity can refer to the angle between two straight lines being between 90°±10°, perpendicularity can also refer to the dihedral angle between two planes being between 90°±10°, and perpendicularity can also refer to the angle between a straight line and a plane being between 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0058] Unless otherwise defined, when the term "plurality" is used to describe the number of components, it specifically means that the components are two or more.

[0067] In some embodiments, the positioning seat 10 includes a positioning member 14. When the first workpiece and the second workpiece are pressed together, the positioning member 14 is used to keep the second workpiece in contact with the first positioning block 12 and the second positioning block 13, thereby reducing the movement of the second workpiece and improving the quality and yield of the pressing.

The pressing head 322 protrudes from the pressing plate body 321. The pressing head 322 is provided with a recess 3221, and the depth of the recess 3221 is less than the thickness of the first workpiece, so that when the pressing head 322 presses the first workpiece, the recess 3221 accommodates part of the first workpiece. During the pressing, the recess 3221 can reduce the movement of the first workpiece relative to the second workpiece, which is conducive to improving the quality and yield of the pressing.

[0074] In some embodiments, the vibrating member 33 includes a connecting plate 331, a fixing plate 332, an elastic member 333 and a vibrating portion 334.

The elastic member 333 is connected to the connecting plate 331 and the fixing plate 332. The vibrating portion 334 is connected to the side of the fixing plate 332 away from the pressing block 32.

[0075] In some embodiments, the connecting plate 331 includes a first connecting plate 331 a and a second connecting plate 331 b , wherein the first connecting plate 331 a connects the pressing power member 31 and the second connecting plate 331 b , and the second connecting plate 331 b connects the fixing plate 332 via an elastic member 333 .

[0076] In some embodiments, the first connecting plate 331a is provided with a first adjustment hole 3311, and the second connecting plate 331b is provided with a second adjustment hole 3312. On the horizontal plane, the extension direction of the first adjustment hole 3311 is perpendicular to the extension direction of the second adjustment hole 3312, which is convenient for adjusting the position of the pressing block 32 on the horizontal plane and is conducive to aligning the pressing block 32 with the first workpiece.

The guide shaft 3331 connects the second connecting plate 331b and the fixed plate 332, and the elastic portion 3332 is sleeved on the guide shaft 3331. When the pressing power member 31 drives the pressing block 32 to press, the second connecting plate 331b can move relative to the guide shaft 3331 and compress the elastic portion 3332, which is conducive to buffering the pressing force of the pressing block 32 to avoid crushing the first workpiece and the second workpiece, and is conducive to the vibration portion 334 driving the pressing block 32 to vibrate.

[0078] In some embodiments, the vibration member 33 includes a plurality of elastic members 333 , each of which is connected to a corner of the second connecting plate 331 b and a corner of the fixing plate 332 .

The motor 3341 is fixed to the side of the fixed plate 332 away from the pressing block 32, and the eccentric block 3342 is connected to the motor 3341. The eccentric block 3342 is driven to rotate by the motor 3341, and the centrifugal force generated by the high-speed rotation of the shaft of the motor 3341 and the eccentric block 3342 is used to obtain the exciting force, which is transmitted to the pressing block 32 through the fixed plate 332, so that the pressing block 32 vibrates.

[0080] In some embodiments, the fixing plate 332 is provided with a groove 3321 . When the motor 3341 drives the eccentric block 3342 to rotate, the groove 3321 is used to accommodate part of the eccentric block 3342 to avoid interference between the eccentric block 3342 and the fixing plate 332 .

[0081] When the above-mentioned pressing device 100 is in use, the heating block 21 is preheated to the required temperature, and the first workpiece and the second workpiece connected in advance by the adhesive are placed on the positioning plate 11, so that the adjacent two sides of the second workpiece abut the first positioning block 12 and the second positioning block 13, the positioning drive member 141 drives the push block 142 to move, and the push block 142 keeps the abutment against the first positioning block 12 and the second positioning block 13. The pressing power member 31 drives the pressing block 32 to press on the first workpiece, and the motor 3341 drives the eccentric block 3342 to rotate. The centrifugal force generated by the high-speed rotation of the shaft of the motor 3341 and the eccentric block 3342 is used to obtain the exciting force.

After the holding time is over, the motor 3341 stops rotating, and the pressing power member 31 drives the pressing block 32 to move away from the first workpiece, and the pressed first and second workpieces are taken out.

[0082] The present application heats the adhesive by the heating element 20, which is helpful to improve the fluidity of the adhesive between the first workpiece and the second workpiece. The vibration element 33 drives the pressing block 32 to vibrate.
