Technical Field
[0001] This application relates to the field of testing technology, and in particular to a workpiece quality inspection machine. Background Technology
[0002] With the continuous development of technology and production, people's living standards are constantly improving. This improvement in living standards means that people's quality requirements for various products are also increasing, and mobile phones have become an indispensable necessity in people's lives. Along with the mass production of mobile phones, related products are also being manufactured simultaneously, such as chargers and data cable interfaces. Mobile phone products prioritize user experience, resulting in stringent requirements for the manufactured products, especially smaller, more delicate items. Despite these stringent requirements, defective products are inevitable during the production process. The occurrence of defective products affects the pass rate of the entire product line and damages the manufacturer's reputation. Smaller products are difficult to identify manually or with ordinary testing equipment, leading to inefficiency and the inability to completely eliminate defective products.

The conveying drive component 22 can engage the vehicle, allowing it to move from one end of the conveying track 21 to the other end. After the vehicle conveying is completed, the conveying drive component 22 separates the vehicle and returns to its original position to receive the conveyed vehicle. A groove 10 is recessed along the direction of the conveying track 21, allowing the vehicle to fit into the conveying track 21. The conveying drive component 22 drives the vehicle to slide along the conveying track 21, positioning and conveying the vehicle within the groove 10, thus improving the stability and accuracy of vehicle transportation.
[0036] In this embodiment, refer to Figure 4 and Figure 5 The support cabinet 1 is equipped with a support frame 11, and the support frame 11 is equipped with a connecting plate 12.

The second transfer component 83 is located on the support cabinet 1 near the loading station 6. After the carrier on the carrier conveying device 2 has been processed by the carrier opening device 4 and the workpiece picking device 5, the carrier conveying device 2 conveys the empty carrier to the first transfer component 81. The first transfer component 81 transfers the carrier to the conveying component 82. The conveying component 82 conveys the carrier towards the second transfer component 83. The conveying component 82 conveys the carrier to the second transfer component 83. The second transfer component 83 transfers the carrier to the loading station 6 on the carrier conveying device 2.

The receiving groove 15 has an opening 16 near the vehicle transfer device 2 and the transfer assembly 82. The second telescopic rod 8323 is extended and retracted by the translation drive 8322, causing the second telescopic rod 8323 to drive the receiving member 8324 to slide towards the vehicle conveying device 2 or towards the conveying assembly 82; the conveying assembly 82 conveys the vehicle to the receiving groove 15 on the receiving member 8324 through the opening 16, so that the vehicle is stably set on the receiving member 8324. The vehicle on the receiving member 8324 is transported to the vehicle conveying device 2 by the translation drive 8322, so that the transfer member 833 can transfer the vehicle on the receiving member 8324 to the vehicle conveying device 2.

The lifting device 1714 moves the pickup 1715 towards the plumb line direction. Preferably, the pickup 1715 is a pneumatic clamp. After the pickup 1715 clamps the workpiece, the lifting device 1714 raises the pickup 1715, completing the unloading process. Good products are picked up, and then the slider 1712 is driven by the feeding drive 1713 to move the picking component 1715 towards the defective product return component 172. When the picking component 1715 moves above the conveyor belt 1721 in the defective product return device, the picking component 1715 releases the defective product. The defective product is conveyed by the conveyor belt 1721, so that the defective product is conveyed to the receiving box 1722 set at the end of the conveyor belt 1721 away from the defective product feeding component 171, thus completing the recycling and collection of defective products.
