[0053] like Figures 1-9 The accompanying drawing shows a structural schematic diagram of a device for testing the performance of injection molded part pins according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0054] This application provides a device for testing the performance of pins on injection molded parts, which performs performance testing on pins provided on the first end face 1010, the first side face 103, and the second side face 1040 of the injection molded part 1000, including:

[0063] In some embodiments, the third inspection station 500 includes a second push rod 510, a first turntable 520, a second side height detection block 530, a second horizontal linear slide module 540, a second top surface height detection block 550, and a second vertical linear slide module 560; the first turntable 520 is used to support and horizontally rotate the injection molded part 1000; the second side height detection block 530 is driven by the second horizontal linear slide module 540 and aligned with the second side 1040; the second top surface height detection block 550 is driven by the second vertical linear slide module 560 and aligned with the top surface near the second side 1040.

[0064] In some embodiments, the fourth inspection station 600 includes a first CCD camera 610 and a third horizontal linear slide module 620; the first CCD camera 610 is driven by the third horizontal linear slide module 620 and is used to perform positional detection on the first end face 1010 of the injection molded part 1000.

[0065] In some embodiments, the fifth inspection station 700 includes a second CCD camera 710, a fourth horizontal linear slide module 720, a second turntable 730, and a first stage 740; the second CCD camera 710 is driven by the fourth horizontal linear slide module 720 and aligned with the side of the injection molded part 1000; the second turntable 730 is used to drive the first stage 740 to rotate, so as to switch the side of the injection molded part 1000 to be inspected.

[0066] In some embodiments, the coding station 800 includes a third push rod 810, a third vertical linear slide module 820 that cooperates with the third push rod 810, a coding machine 830, and a second platform 840; the coding machine 830 is disposed on the third vertical linear slide module 820; the third push rod 810 is used to adjust the horizontal position of the coding machine 830; the second platform 840 is used to support the injection molded part 1000; the position of the coding machine 830 is adjusted by the cooperation of the third push rod 810 and the third vertical linear slide module 820 so that the coding machine 830 is directly facing the injection molded part 1000.

[0067] In this invention, all linear slide modules can be driven by screws or synchronous belts.

[0068] In practical applications, the detection process of this utility model is as follows:

[0069] The operator or the loading robot places the injection molded part 1000 to be inspected on the unloading station 200. The suction cup 110 of the transfer gripper assembly 100 moves above the unloading station 200, descends and uses vacuum suction to pick up the injection molded part 1000, and then transfers it to the first inspection station 300;

[0070] At the first inspection station 300, the conductivity performance of multiple pins on the first end face 1010 of the injection molded part 1000 is mainly tested. This station includes a fifth slide 310, a fifth linear guide 320, a sixth slide 330, a sixth linear guide 340, and a conductivity testing block 350. The fifth slide 310 can move along the fifth linear guide 320, and the sixth slide 330 can move along the sixth linear guide 340 to drive the conductivity testing block 350 to be precisely positioned on the plane. The bottom surface of the conductivity testing block 350 is provided with several detection probes (not shown in the figure) that precisely match the pin layout on the first end face 1010. These probes are preferably elastic probes to ensure good electrical contact with the pins. After the injection molded part 1000 is positioned, the conductivity testing block 350 moves downward under the drive of the slide, so that the probes contact all the pins at the same time, thereby quickly completing the conductivity test of the entire row of pins.

[0071] After completing the first inspection station, the transfer gripper assembly 100 moves the injection molded part 1000 to the second inspection station 400. This station is used to inspect the height of the pins on the first side 1030 and the height of the top surface near that side. This station includes a first push rod 410, which acts to abut the injection molded part 1000 from the other side (second side 1040) to provide a stable inspection reference. The first side height detection block 420 is driven by the first horizontal linear slide module 440 and can move horizontally to a position facing the first side 1030, and then move forward to contact or measure the height of the pins on that side. At the same time, the first top surface height detection block 430 is driven by the first vertical linear slide module 450 and can move to a position facing the top surface near the first side 1030, and then descend to measure the height of the pins on the top surface of that area.

[0072] Subsequently, the injection molded part 1000 is transferred to the third inspection station 500, which is used to inspect the height of the pins on the second side 1040 and the height of the top surface near that side. Its structure is similar to the second inspection station 400 but targets a different side and adds a rotation function. It includes a second push rod 510 and a first turntable 520 for supporting and horizontally rotating the injection molded part 1000. When the injection molded part 1000 is placed on the first turntable 520, the first turntable 520 rotates a certain angle (e.g., 90 degrees or 180 degrees, depending on the initial orientation), causing the second side 1040, which was originally facing the other side, to rotate to a position convenient for inspection, and is positioned by the second push rod 510 from the opposite side (first side 1030). The second side height detection block 530 is driven by the second horizontal linear slide module 540 to align and inspect the pin height of the second side 1040. The second top surface height detection block 550 is driven by the second vertical linear slide module 560 to descend and detect the height of the top surface area near the second side 1040.

[0073] The next fourth inspection station 600 is used to perform high-precision visual inspection of the position of the pins on the first end face 1010. The fourth inspection station 600 includes a first CCD camera 610 and a third horizontal linear slide module 620. The first CCD camera 610 is driven by the third horizontal linear slide module 620 and can move along the extension direction of the first end face 1010 to scan and photograph all the pins on it. The image processing algorithm is used to accurately determine whether the position of each pin is within the allowable tolerance range.

[0074] Subsequently, the injection molded part 1000 is transferred to the fifth inspection station 700 for visual inspection of the position of the side inserts. The fifth inspection station 700 includes a second CCD camera 710, a fourth horizontal linear slide module 720, a second turntable 730, and a first stage 740; the injection molded part 1000 is placed on the first stage 740. The second CCD camera 710 is driven by the fourth horizontal linear slide module 720, and can move horizontally to scan and photograph one side of the injection molded part 1000 (such as the first side 1030). After the inspection of one side is completed, the second turntable 730 drives the first stage 740 and the injection molded part 1000 on it to rotate, rotating the next side to be tested (such as the second side 1040) to a position facing the second CCD camera 710, and continuing the inspection, thereby realizing automated position inspection of multiple sides.

[0075] After all inspection stations are completed, the transfer gripper assembly 100 transfers the qualified injection molded part 1000 to the coding station 800. This station is used to mark a unique identifier on the product. It includes a third push rod 810, a third vertical linear slide module 820, a coding machine 830, and a second stage 840. The injection molded part 1000 is placed on the second stage 840; the coding machine 830 (preferably a laser marking machine) is mounted on the third vertical linear slide module 820, and its vertical height can be adjusted. The third push rod 810 is used to cooperate with the third vertical linear slide module 820 to fine-tune the horizontal position of the coding machine 830, ensuring that the light outlet of the coding machine 830 is aligned with the predetermined coding area on the injection molded part 1000. After adjustment, the coding machine 830 will engrave a QR code containing the inspection information (such as serial number, inspection date, result code, etc.) on the surface of the product.

[0076] Finally, the coded and qualified products are picked up by the transfer gripper assembly 100 and placed onto the assembly line conveyor belt 900, which automatically transports them to the subsequent packaging area. Unqualified products can be placed in a designated waste collection area during the transfer process.

[0077] In summary, the present invention has a reasonable structure. The transfer gripper assembly 100 transports the injection molded parts 1000 to each inspection station in sequence. The end face and side face of the injection molded parts 1000 containing the pins are tested for conductivity, height and position in sequence. The qualified products are marked with QR codes for traceability, avoiding human error and achieving efficient and accurate quality inspection.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
