The stamped hardware parts are transferred to the centralized loading transfer mechanism 3. The nut loading mechanism 4 is used to transfer nuts to the centralized loading transfer mechanism 3. The fully automatic embedding system 2 is located on one side of the nut loading mechanism 4 and is used to transport the hardware parts and nuts to the injection mold 5 for pre-embedding. The injection mold 5 injects the hardware parts and nuts into the product while forming the product's shape. The semi-finished product unloading mechanism 6 is located on one side of the injection mold 5. The fully automatic embedding system 2 is used to transfer the formed product in the injection mold 5. In the semi-finished product unloading mechanism 6, the connector PIN punching device 7 is set on one side of the semi-finished product unloading mechanism 6. The semi-finished product unloading mechanism 6 performs injection molding defect detection on the molded product. If there is a defect, it is unloaded as NG.

The finished product unloading mechanism D is set on one side of the CCD size testing mechanism C and is used to unload the product.

[0047] During operation, the hardware feeding and stamping transfer mechanism 1 processes the hardware parts, turning the hardware strip into individual PIN hardware parts, and then transfers them to the centralized feeding transfer mechanism 3. Simultaneously, the nut feeding mechanism 4 transfers the nuts to the centralized feeding transfer mechanism 3. After centralized feeding, the fully automatic embedding system 2 uses a six-axis robotic arm to grab the PIN hardware parts and multiple nuts, embedding them into the injection mold 5 in one go. After the nuts and PIN hardware parts are embedded, the six-axis robotic arm removes the previously molded semi-finished product. The six-axis robotic arm then transfers the semi-finished product to the semi-finished product unloading mechanism 6 for unloading. The semi-finished product unloading mechanism 6 flips the semi-finished product and transfers the connector PIN punch. In the cutting device 7, after the connector PIN punching device 7 completes the punching of the PIN metal material, the injection molding semi-finished product is transferred to the sprue shearing mechanism 8. After the sprue shearing mechanism 8 completes the processing of the material head, the injection molding semi-finished product is transferred to the electrical performance testing mechanism 9.

After the snap-fit ​​and nut assembly is completed, the relevant dimensions of the injection molding product are inspected at the CCD dimension inspection station. After the dimension inspection is completed, the finished product unloading mechanism D unloads the injection molding product. In summary, this application requires no manual operation, greatly improving processing efficiency.

Then, the multi-axis robot 24 rotates to the other side, and the copper sheet gripping device 23 on the other side comes to the copper sheet picking position of the feeding fixture 26. The copper sheet gripping device 23 grabs the irregular copper sheet. Finally, the irregular copper sheet, nuts and screws are placed into the injection mold of the injection molding machine 21.

[0067] In this embodiment, as Figure 13 As shown, the injection mold 300 includes an upper mold 31 and a lower mold 32. The upper mold 31 includes a panel 311, a hot runner plate 312, and an A plate 313 arranged sequentially from top to bottom. A front mold core 314 is provided on the bottom surface of the A plate 313. A hot runner system is provided inside the upper mold 31, which includes a needle valve 315, a hot nozzle 316, and a first injection channel 317. The needle valve 315 is provided on the panel. The upper part of the hot nozzle 316 is provided inside the hot runner plate 312 and connected to the needle valve 315. The lower part of the hot nozzle 316 is provided inside the A plate 313 and connected to the front mold core 314. The first injection channel 317 in section 4 is connected. The lower mold 32 includes a B plate 321, a square iron 322 and a base plate 323 arranged from top to bottom. A rear mold core 324 is provided on the B plate 321 corresponding to the front mold core 314. After the front mold core 314 and the rear mold core 324 are closed, they form a product cavity. A first slider 325 is provided on the right side of the rear mold core 324 and a second slider 326 is provided on the left side of the rear mold core 324. An ejector plate 327 and an ejector base plate 328 are provided on the base plate and located between the square iron 322. An ejector spring 329 is provided on the ejector plate 327.

[0068] During operation, the upper mold 31 and the lower mold 32 first close together, and then the hot runner system starts. The rubber material enters the hot nozzle 316 from the needle valve 315. The hot nozzle 316 continuously heats the rubber material to prevent it from cooling and hardening. Finally, the rubber material enters the front mold core 314 and the rear mold core 324 from the first inlet runner 317 and the molds close together to form the product cavity. The hot runner system in this application has three parts, and the inlet runner of each hot runner system is located on the side of the product. This ensures that the top surface of the product is free of defects. In addition, for thin products, this application can save raw materials, improve the molding cycle, and reduce subsequent processes.

[0069] like Figure 13 As shown, in this embodiment, a heat insulation plate 318 is provided on the upper surface of the panel to prevent the heat of the upper mold 31 from being directly transferred to the main unit and injuring the operator.

[0070] like Figure 13 As shown in this embodiment, the front mold core 314 is provided with multiple cooling water channels 319, which are used to cool the product after molding and accelerate the product's setting.

[0071] like Figure 13 As shown, in this embodiment, a slider limiting block 33 is provided on the right side of the first slider 325. Its function is to prevent the movement stroke of the first slider 325 from exceeding the position of the slider limiting block 33.

[0072] like Figure 13 As shown in this embodiment, wear-resistant blocks 34 are provided on both the first slider 325 and the second slider 326. This is mainly to reduce wear on the first slider 325 and the second slider 326, because the first slider 325 and the second slider 326 have poor wear resistance, are difficult to process, and replacement is costly. Adding wear-resistant blocks extends the service life of the first slider 325 and the second slider 326, reducing replacement costs.

[0073] like Figure 13 As shown in this embodiment, the ejector plate 327 is provided with a waste pin 35 and a support block 36. The purpose of providing the waste pin 35 is to reduce the contact area between the ejector base plate 328 and the lower fixed plate, and to prevent the mold from not closing properly due to waste and dust falling onto the ejector base plate 328 and the lower fixed plate. The purpose of providing the support block 36 is to prevent the ejector plate 327 from directly colliding with the B plate 321 when it moves upward, thereby damaging the ejector pin 37.

[0074] like Figure 14 As shown in this embodiment, the ejector base plate 328 is provided with an ejector pin 37 and an ejector sleeve pin 38.

[0075] In this embodiment, as Figure 15As shown, the connector PIN punching device 7 includes a base plate 71, a mounting bracket 72, a punching die 73, and a double start switch 74. When starting, the double start switch 74 needs to be pressed simultaneously for the drive device 733 to work, thereby preventing worker misoperation.

[0076] like Figures 15 to 16 As shown, in this embodiment, the mounting bracket 72 is mounted on the base plate 71. The punching die 73 includes an upper die 731, a lower die 732, a driving device 733, a large guide post 734, and a guide sleeve 735. The upper end of the guide post is mounted on the top of the mounting bracket 72, and the lower end of the guide post is mounted on the base plate 71. The upper die 731 is mounted on the guide post through the guide sleeve 735. The driving device 733 is located on the upper part of the mounting bracket 72 and connected to the upper die 731. The driving device 733 can drive the upper die 731 to move up and down. The lower die 732 is set... Below the upper mold 731, the upper mold 731 includes a lifting plate 7311, a first mounting plate 7312, a second mounting plate 7313, an upper cutter, and a pressure plate 7314. The first mounting plate 7312 is mounted on the bottom of the lifting plate 7311. The upper cutter is mounted on the first mounting plate 7312 via the second mounting plate 7313. The pressure plate 7314 is located at the bottom of the second mounting plate 7313. The upper cutter includes a first upper cutter 7315 and a second upper cutter 7316. The bottom surface of the first upper cutter 7315 is a plane.

[0077] like Figure 17 As shown, the bottom surface of the second upper cutter 7316 is provided with a cutter groove 73161, and the cutter groove 73161 and the four sides of the second upper cutter 7316 respectively form a first cutting edge a, a second cutting edge b, a third cutting edge c and a fourth cutting edge d.

[0078] During operation, the connector is placed on the lower mold 732, and then the drive device 733 drives the lifting plate 7311 and the pressure plate 7314 of the upper mold 731 to descend. First, the pressure plate 7314 presses the connector firmly onto the lower mold 732. Then, the upper cutter on the first mounting plate 7312 continues to descend, thereby cutting the connecting material between the pins in the connector. This application achieves this by using the bottom surface of the second upper cutter 7316, such as... Figure 18As shown, a cutting groove 73161 is provided, which, together with the four sides of the second upper cutter 7316, forms a first cutting edge a, a second cutting edge b, a third cutting edge c, and a fourth cutting edge d, respectively. The second upper cutter 7316 has multiple cutting edges for cutting. The simultaneous action of multiple cutting edges on the material balances the pressure on the second upper cutter 7316 during cutting, reducing the possibility of blade breakage. Furthermore, the interconnected multiple cutting edges increase the force-bearing area of ​​the blade, improving the overall load-bearing capacity and reducing breakage. Multiple cutting edges also enhance the sharpness of the blades, thereby improving cutting efficiency. In summary, this application eliminates the need for manual cutting, not only improving cutting efficiency but also reducing the labor intensity of workers.

[0079] like Figure 17 As shown in this embodiment, the lower mold 732 is provided with a lower cutter corresponding to the upper cutter. The lower cutter includes a first lower cutter 7321 and a second lower cutter 7322. The first lower cutter 7321 corresponds to the first upper cutter 7315, and the second lower cutter 7322 corresponds to the second upper cutter 7316. Both the first lower cutter 7321 and the second lower cutter 7322 are cutting through grooves, and their cutting edges are provided with chamfers to improve the sharpness of the cutter.

[0080] like Figure 16 As shown in this embodiment, the pressure plate 7314 is provided with a clearance portion 73141. The clearance portion 73141 allows the pressure plate 7314 to avoid the protruding area on the upper part of the connector when it is pressed down.

[0081] like Figure 17 As shown in this embodiment, the pressure plate 7314 is provided with a cutter guide groove 73142.

[0082] In this embodiment, the lower mold 732 is also provided with a positioning groove 7323 for positioning the connector PIN pins.

[0085] like Figure 19As shown in Figure 20, the sprue shearing mechanism 8 is used to shear the sprues on both sides and the bottom of the product. It includes a shearing device 81, a positioning device 82, and a positioning fixture base 83. The positioning fixture base 83 is disposed between the shearing device 81 and the positioning device 82. The shearing device 81 includes a base plate 811, a moving plate 812, a first driving device 813, a first shearing assembly 814, and a second shearing assembly 815. The first shearing assembly 814 is disposed on both sides of the moving plate 812. The moving plate 812 is mounted on the first driving device 813, and the first driving device 813 is mounted on the base plate 811. The first driving device 813 drives the moving plate 812 to move the first shearing assembly 814 closer to the sprues on both sides of the product d. The first shearing assembly 814 is used to cut the sprues on both sides of the product d. The second shearing assembly 815 is disposed at the bottom of the positioning device 82 and is used to cut the sprues at the bottom of the product d.

[0086] In operation, the product d is first placed on the positioning fixture base 83, and then the positioning device 82 is activated. The positioning device 82 is positioned opposite to the cutting device 81. The positioning device 82 can abut against the part of the product d where the sprue needs to be cut. In this way, when the cutting device 81 approaches the sprue of the product d, the positioning device 82 can prevent the product d from shifting backward when it is cut by the cutting device 81. In addition, this application is provided with a first cutting component 814 and a second cutting component 815. The first cutting component 814 can quickly and simultaneously cut off the sprue on both sides of the product d, while the second cutting component 815 can also simultaneously cut off the sprue at the bottom of the product d.

[0089] like Figure 21 As shown, when the upper blade 8143 moves forward, it also drives the lower blade 8144 to move forward. Under the action of the drive groove 8147, the drive column 8148 of the lower blade 8144 moves upward along the horizontal part b to the inclined part a, thereby driving the lower blade 8144 to rotate counterclockwise around the rotating shaft 8146, so that the blades of the upper blade 8143 and the lower blade 8144 are in a closed state, thereby cutting off the sprue.

[0090] like Figure 22 As shown, when the upper cutting part 8143 moves backward, it will drive the lower cutting part 8144 to move backward. Under the action of the driving groove 8147, the driving column 8148 of the lower cutting part 8144 moves downward along the inclined part a to the horizontal part b, thereby driving the lower cutting part 8144 to rotate clockwise around the rotating shaft 8146, so that the cutting heads of the upper cutting part 8143 and the lower cutting part 8144 are in an open state.

[0091] like Figure 23 As shown, in this embodiment, the head of the shearing blade holder 8142 is provided with a chamfer c to facilitate the installation of the upper blade 8143 and the lower blade 8144.
