[0075] Reference Figure 3 The platen loading mechanism 2 has a platen loading fixture 21 that can move horizontally and vertically. The platen delivered to the platen loading station from the outside is clamped by the platen loading fixture 21 and delivered to the offset tooling 32 of the platen assembly mechanism 3.

[0076] Reference Figure 1 and Figure 2 The platen assembly mechanism 3 is located between the platen feeding mechanism 2 and the turntable 1. The platen assembly mechanism 3 is used to send the platen sent by the platen feeding mechanism 2 to the product tooling 11 on the turntable 1 after adjusting the angle. Figure 4 and Figure 5 The pressing plate assembly mechanism 3 includes a pressing plate feeding fixture 31, a misalignment tooling 32 and a pressing plate angle camera 33.

[0077] The platen feeding fixture 31 is capable of horizontal movement, vertical movement and rotation. A dislocation tool 32 is provided on the lower side of the platen feeding fixture 31 , and a platen angle camera 33 is provided above the dislocation tool 32 .

[0078] In specific implementation, the dislocation tool 32 receives the pressing plate sent from the pressing plate feeding mechanism 2, and the pressing plate angle camera 33 above the dislocation tool 32 takes a picture of the pressing plate, and determines whether the pressing plate angle is consistent with the preset assembly angle based on the existing image recognition technology. The existing image comparison technology can be used for recognition, such as presetting a pressing plate template angle diagram for comparison to obtain the angle that needs to be rotated. The pressing plate feeding fixture 31 clamps the pressing plate, rotates according to the angle, and sends the pressing plate that has reached the assembly angle to the product tool 11 of the turntable 1.

[0079] The pressure plate detection mechanism 4 is used to detect the height of the pressure plate, refer to Figure 1 and Figure 2 The pressure plate detection mechanism 4 is located between the pressure plate assembly mechanism 3 and the diaphragm assembly mechanism 6.

[0080] The diaphragm feeding mechanism 5 has a diaphragm feeding fixture that can move horizontally and vertically.

[0083] During the specific implementation, the diaphragm rotating table 62 receives the diaphragm sent out from the diaphragm feeding mechanism 5, and the diaphragm angle camera 63 above the diaphragm rotating table 62 takes a picture of the diaphragm, and determines whether the diaphragm angle is consistent with the preset assembly angle based on the existing image recognition technology. The existing image comparison technology can be used for recognition. For example, a preset diaphragm template angle diagram is used for comparison to obtain the angle required for rotation. After the diaphragm rotating table 62 rotates according to the angle, the diaphragm feeding fixture 61 clamps the diaphragm and sends the diaphragm that has reached the assembly angle to the product tooling 11 of the turntable 1.

[0084] Reference Figure 1 and Figure 2The diaphragm pressing mechanism 7 is located on the side of the diaphragm assembly mechanism 6, and the diaphragm pressing mechanism 7 has a diaphragm pressing block that can move vertically. The diaphragm pressing mechanism 7 is used to apply force to the diaphragm and the pressing plate on the product tooling 11 rotated to the pressing station through the diaphragm pressing block to press the center hole and the two side corners of the diaphragm to the pressing plate below it and press them into place to obtain a finished product.

[0085] Reference Figure 1 and Figure 2 The finished product detection mechanism 8 is located between the diaphragm pressing mechanism 7 and the finished product discharging mechanism 9.

[0087] Reference Figure 1 and Figure 2 The residual material detection mechanism 10 is located on the side of the finished product discharging mechanism 9. The residual material detection mechanism 10 detects whether there are products that have not been taken up on the product tooling 11 on the turntable 1 rotated from the finished product discharging mechanism 9, and ensures that the product tooling 11 is empty when it is transferred to the pressing plate loading station.

The end of the piston of the third cylinder 37 for platen assembly is provided with a dislocation tool 32.

[0098] The third cylinder 37 for assembling the pressure plate is used to horizontally move the offset tooling 32. After the offset tooling 32 receives the pressure plate, it is first moved to directly below the pressure plate angle camera 33. After the photo is taken, it is moved to directly below the pressure plate feeding fixture 31.

[0123] During the specific implementation, the finished product discharging fixture 91 will be transferred to the finished product clamped on the product tooling 11 at the discharging station, and moved to the preset position above the finished product discharging cylinder 92. The finished product discharging cylinder 92 will move the finished product discharging channel 93 or the unqualified product channel 95 to directly below the preset position according to the detection results of the pressure plate detection mechanism 4 and / or the finished product detection mechanism 8.
