The pressing plate 400 attracts one of the intermediate products by magnetic attraction or vacuum attraction, and moves toward the other intermediate product positioned on the worktable under the driving action of the driving mechanism 100, so that the two intermediate products are attached to each other.
Specifically, the drive mechanism 100 is a motor having an output shaft 110.

When the output shaft 110 of the driving mechanism 100 rotates, the lead screw 210 is driven to rotate together, so that the nut 220 moves along the lead screw 210, and thus the hydraulic assembly 300 and the compression plate 400 can move linearly. That is, transmission assembly 200 is capable of converting rotational motion of drive mechanism 100 into linear motion of hydraulic assembly 300.
In the present embodiment, the transmission assembly 200 further includes a coupling 230, and the coupling 230 is used for connecting the driving mechanism 100 and the lead screw 210, and specifically, the coupling 230 is used for connecting the output shaft 110 and the lead screw 210. The coupling 230 can not only transmit the rotation motion of the output shaft 110 to the lead screw 210 to realize the synchronous rotation of the output shaft 110 and the lead screw 210, but also protect the lead screw 210 and prevent the lead screw 210 from bearing an excessive load. It will be appreciated that in other embodiments, the lead screw 210 may be rigidly connected directly to the output shaft 110, and the coupling 230 may be omitted.
The hydraulic assembly 300 includes a cylinder 310 and a cylinder shaft 320, the cylinder 310 includes a first side wall 312 and a second side wall 314 disposed opposite to each other, and a direction from the first side wall 312 to the second side wall 314 is parallel to an axial direction of the lead screw 210. A cavity for storing hydraulic oil 330 is arranged in the oil cylinder 310, a guide hole 302 is further formed in the oil cylinder 310, the guide hole 302 is communicated with the cavity and penetrates through the first side wall 312, and an axis of the guide hole 302 extends along a direction from the first side wall 312 to the second side wall 314.

The end of the cylinder shaft 320 away from the second side wall 314 is formed with a groove 322, and the end of the screw 210 away from the driving mechanism 100 is formed through the groove 322. Under the driving action of the driving mechanism 100, the nut 220 moves along the lead screw 210, when the nut 220 moves towards the second side wall 314, the length of the lead screw 210 accommodated in the groove 322 becomes smaller, and when the nut 220 moves away from the second side wall 314, the length of the lead screw 210 accommodated in the groove 322 becomes larger.
The cylinder shaft 320 is coupled to the nut 220 such that the cylinder shaft 320 can move toward or away from the second sidewall 314 along the axial direction of the guide hole 302 with respect to the cylinder 310 along with the nut 220. Furthermore, in the present embodiment, the projection of the guide hole 302 on the second sidewall 314 falls within the projection of the nut 220 on the second sidewall 314. Therefore, when the cylinder shaft 320 moves a certain distance toward the second side wall 314 along with the nut 220, the nut 220 abuts against the oil cylinder 310, and at this time, the oil cylinder 310 and the cylinder shaft 320 move together along with the nut 220 toward a workbench carrying another intermediate product.
The oil cylinder 310 is filled with hydraulic oil 330, when the cylinder shaft 320 is close to the second side wall 314 along the axial direction of the guide hole 302 relative to the oil cylinder 310 along with the nut 220, the cylinder shaft 320 can extrude the hydraulic oil 330, according to the characteristic that the force transmission of the oil is uniform, the hydraulic oil 330 can uniformly apply pressure to the inner wall of the oil cylinder 310, the oil cylinder 310 transmits the pressure to the extrusion plate 400 uniformly, and the extrusion plate 400 is uniform in stress and not easy to distort. Moreover, when the oil cylinder 310 drives the extrusion plate 400 to press two intermediate products, not only the impact force on the intermediate products can be greatly reduced, but also the stress on the intermediate products can be balanced, thereby preventing the intermediate products from being deformed or even damaged, and improving the yield of electronic products.
When the two intermediate products are attached, the output shaft 110 of the driving mechanism 100 rotates in the opposite direction, the nut 220 moves away from the second side wall 314 along the lead screw 210, and the cylinder shaft 320 moves away from the second side wall 314 along with the nut 220.

The automatic retracting mechanism 500 may be a nitrogen spring or a general tension spring.
It should be noted that, in addition to the transmission assembly 200 of the present embodiment, other transmission forms may also be adopted, such as a slide guide, and the driving mechanism 100 may be an air cylinder or a push rod motor, and directly drives the slide to slide along the guide, so as to drive the cylinder shaft 320 connected with the slide to move. Of course, in other embodiments, transmission assembly 200 may be omitted such that drive mechanism 100 directly drives cylinder shaft 320 to move linearly.

The guide tube 350 includes a first end and a second end opposite to each other, the guide hole 302 penetrates the first end and the second end, the first end is accommodated in the cavity, and the first sidewall 312 is located between the first end and the second end. The design of the conduit 350 not only can increase the contact area between the cylinder shaft 320 and the cylinder 310 to improve the stability of the movement of the cylinder shaft 320 when the cylinder shaft 320 moves relative to the cylinder 310 toward the second side wall 314, but also can prevent the hydraulic oil 330 from overflowing the cylinder 310. In other embodiments, the guide tube 350 can be omitted and the guide hole 302 can be directly formed on the first sidewall 312.
In addition, the nut 220 abuts against the cylinder 310, that is, the nut 220 abuts against the guide pipe 350, and besides the manner can drive the cylinder 310 and the cylinder shaft 320 to move together, a baffle plate can be disposed on the inner wall of the guide hole 302 or on the first end of the guide pipe 350, when the cylinder shaft 320 moves a certain distance along the axial direction of the guide hole 302 towards the second side wall 314, the cylinder shaft 320 abuts against the baffle plate, and thus the cylinder shaft 320 also drives the cylinder 310 to move together.

In the present embodiment, the area of the side of the pressing plate 400 away from the second sidewall 314 is smaller than the area of the side of the second sidewall 314 away from the cavity. Thus, the oil cylinder 310 with a large area transmits pressure to the compression plate 400 with a small area, so that the compression plate 400 can be uniformly stressed, and the compression plate 400 is prevented from being distorted due to large stress in the middle and small stress at two ends of the compression plate 400.
In this embodiment, the bonding apparatus 10 further includes a pressure tester 600, and the pressure tester 600 is connected to the oil cylinder 310 and can detect the pressure value of the hydraulic oil 330.
