[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] See Figures 1 to 5 To further elaborate on this application:

[0036] The integrated fixture 100 includes a material gripping mechanism 2, which is used to grip and transfer the sheet material and the cake material 01; it can place the arranged sheet material and the cake material 01 into the compression molding machine for processing, and place the compression-molded semi-finished sheet material 00 in the placement tray.

[0037] The semi-finished product gripping mechanism 3 is used to grip and transfer the semi-finished product sheet 00; it can grip the semi-finished product sheet 00 placed in the tray and send it into the stamping device to remove excess glue.

[0038] Mounting frame 1, the material gripping mechanism 2 and the semi-finished product gripping mechanism 3 are respectively located on both sides of the mounting frame 1; the semi-finished product gripping mechanism 3 is connected to the mounting frame 1 by a flipping mechanism 4, which is used to drive the semi-finished product gripping mechanism 3 to flip independently.

[0039] In this embodiment, the flipping mechanism 4 includes a power unit 41 and a bearing seat 43, as well as a rotating shaft 42 connecting the power unit 41 and the semi-finished product gripping mechanism 3. The bearing seat 43 supports the rotation of the rotating shaft 42. The power unit 41 can be a flipping cylinder. During operation, after the semi-finished product gripping mechanism 3 picks up the semi-finished product sheet 00, the power unit 41 drives the rotating shaft 42 to rotate the semi-finished product gripping mechanism 3 180 degrees, thus making it suitable for reverse adhesive application processes. In other embodiments not shown, the power unit 41 can also be a motor.

[0040] The semi-finished product gripping mechanism 3 of this application is connected to the mounting frame 1 by the flipping mechanism 4, which can flip the semi-finished product gripping mechanism 3 by 180 degrees; thus, the fixture can be used not only for traditional glue-pressing process requirements, but also for reverse glue-pressing process requirements, and the material gripping mechanism 2 and the semi-finished product gripping mechanism 3 are integrated on the same mounting frame 1, thereby reducing the space occupied.

[0041] It should be noted that the semi-finished material sheet 00 in the figure includes two sheets, with the middle connecting part being the residual glue after compression molding.

[0042] In this embodiment, the semi-finished product gripping mechanism 3 includes a fixed frame 31 with a through groove 310 in the middle, and a plurality of claw components 32 disposed in the through groove 310. The claw components 32 can open and close synchronously to grip or place the semi-finished product sheet 00.

[0043] The second claw assembly 32 includes a driving part 321 and a clamping part 322, as well as an elastic component 323 disposed between the clamping part 322 and the fixed frame 31. The elastic component 323 may be a spring. The clamping part 322 is rotatably connected to the fixed frame 31 in the middle. Specifically, a rotating shaft 324 is provided between the clamping part 322 and the fixed frame 31.

[0044] The clamping part 322 is provided with a notch 3220 for clamping the semi-finished material sheet 00. The notch 3220 is located on the side near the through groove 310. When the second claw assembly 32 closes inward, the edge of the semi-finished material sheet 00 is caught in the notch 3220 to grasp the semi-finished material sheet 00. Then, when the flipping mechanism 4 drives the semi-finished product gripping mechanism 3 to flip, the semi-finished material sheet 00 will not fall off the second claw assembly 32.

[0045] In this embodiment, the material gripping mechanism 2 includes a base plate 21 and a clamping assembly 24, as well as several pairs of gripping modules 22 disposed on the base plate 21 for gripping material pieces; gripping modules 23 are disposed between the gripping modules 22, and the clamping assembly 24 is used to cooperate with the gripping modules 23 to fix the material cake 01. There are six pairs of gripping modules 22, arranged parallel to each other; this arrangement allows for the simultaneous pickup of placed material pieces and material cakes 01.

[0046] The second clamping module 23 includes a material cylinder plate 231, on which a plurality of placement slots 232 for placing the material cake 01 are provided. The clamping assembly 24 is used to fix the material cake 01 in the placement slots 232. During pickup, the material cake 01 moves into the placement slots 232, and the bottom of the material cake 01 is supported by the clamping assembly 24 to achieve pickup of the material cake 01.

[0047] The clamping assembly 24 includes a power component 241 and several movable plates 242, as well as a drive plate 243 connecting the power component 241 and the movable plates 242; each movable plate 242 corresponds to one or more clamping modules 22; the movable plate 242 is provided with a baffle 244 extending into the bottom end of the clamping module 23.

[0048] In this embodiment, the power component 241 can be a cylinder; in use, the power component 241 drives the movable plate 242 to move synchronously via the drive plate 243. Figure 1 (The middle moves left and right), thereby causing the baffle 244 to move and cover the bottom of the placement groove 232, preventing the material cake 01 in the placement groove 232 from falling out.

[0049] The gripping module 22 includes a fixed plate 221 and a claw assembly 222 mounted on the fixed plate 221. The claw assembly 222 can open and close synchronously to grip or place material pieces. The claw assembly 222 can be driven by a cylinder to rotate the grippers, thereby enabling the picking and placing of material pieces; alternatively, the claw assembly 222 can also employ an existing gripping mechanism.

[0050] In this embodiment, a detection component 25 is also included. The detection component 25 includes a first detection component 252 and a second detection component 251. The first detection component 252 is used to detect the material sheet being picked up or placed by the first clamping module 22, and the second detection component 251 is used to detect the material cake 01 being picked up or placed by the second clamping module 23. Both the first detection component 252 and the second detection component 251 can be photoelectric sensors.

[0051] Combination Figure 1 In some embodiments, at least one reinforcing plate 5 is provided between the mounting frame 1 and the material gripping mechanism 2 to improve the connection strength and rigidity between the mounting frame 1 and the material gripping mechanism 2.

[0052] Combination Figure 6 This application also provides a transfer device, which includes the aforementioned integrated clamp 100 and a drive device 6. The drive device 6 is connected to the middle of the mounting frame 1 and is used to drive the integrated clamp 100 to move and / or rotate in space. The drive device 6 may be a robotic arm.

[0053] First, the drive device 6 drives the material gripping mechanism 2 to pick up the placed material pieces and biscuits 01 and place them in the compression molding machine for processing.

[0054] Secondly, after processing is completed, the semi-finished material sheet 00 is placed in the placement tray by driving the material gripping mechanism 2.

[0055] Then, the drive device 6 drives the integrated clamp 100 to rotate and switch the semi-finished product gripping mechanism 3.

[0056] Finally, the semi-finished product gripping mechanism 3 sequentially places the semi-finished product sheets 00 in the tray into the stamping device for degumming. Before placing them into the stamping device, the state of the semi-finished product sheets is adjusted according to the degumming process.
