Description

Technical Field

[0001] This application relates to the field of electronic product testing, and in particular to a size testing device. Background Technology

[0002] With the development of the electronics industry, the quality requirements for electronic product components are becoming increasingly stringent. When electronic products leave the factory, their dimensions are typically inspected, such as for foldable screens. The inspection process in related technologies is semi-automated, requiring inspection of both the front and back of the product. The product to be inspected is placed on a tray, then placed at the inspection station. After the front inspection is completed, the product is manually flipped over for inspection of the back.

[0003] Semi-automated detection methods in related technologies are relatively slow, and manually flipping the product may damage it. Summary of the Invention

[0055] The first inspection table 300 is located on one side of the conveying device 200. The conveying device 200 is used to drive the first suction cup frame 250 to pick up the product from the feeding device 100 and transport the product to the first inspection table 300.

[0056] The first detection device 400 is located above the first detection table 300 and is used to perform dimensional detection on the product located on the first detection table 300.

[0057] The auxiliary flipping device 500 and the conveying device 200 are also used to drive the first suction cup frame 250 to place the product that has been detected by the first detection table 300 into the auxiliary flipping device 500, and drive the second suction cup frame 260 to pick up the product located in the auxiliary flipping device 500.

[0059] The second inspection device 700 is located above the second inspection table 600 and is used to inspect the size of the product located on the second inspection table 600.

[0060] The unloading device 800 and the loading device 100 are respectively located on opposite sides of the first linear drive unit 210; the conveying device 200 is also used to drive the first suction cup frame 250 to transport the product located on the second inspection table 600 to the unloading device 800.

[0061] The dimension detection device according to the embodiments of this application has at least the following beneficial effects: In the dimension detection device of the embodiments of this application, the product to be dimensionally detected is placed in the feeding device 100. The first mounting base 220 is driven to reciprocate by the first linear drive unit 210, so that the first mounting base 220 approaches the feeding device 100. The first support frame 240 is driven to lift by the second linear drive unit 230, thereby driving the first suction cup frame 250 to approach the feeding device 100. The product is picked up from the feeding device 100 by the first suction cup frame 250, and then transported to the first detection table 300 by the first linear drive unit 210 and the second linear drive unit 230 and the first suction cup frame 250. On the first inspection table 300, the first inspection device 400 inspects one side of the product. Then, the first linear drive unit 210 and the second linear drive unit 230 drive the first suction cup 250 to pick up the product from the first inspection table 300 and transport it to the auxiliary flipping device 500. The first linear drive unit 210 and the second linear drive unit 230 then drive the second suction cup 260 to approach the auxiliary flipping device 500 and pick up the product located in the auxiliary flipping device 500. The flipped product is then placed on the auxiliary flipping device 500. The first suction cup 250 then transports the flipped product to the second inspection table 600, where the second inspection device 700 inspects the product. This completes the inspection of both sides of the product. Finally, the first suction cup 250 transports the product to the unloading device 800 for unloading. Thus, the size inspection equipment of this embodiment achieves automated product inspection, particularly by completing the product flipping without manual operation, improving production efficiency and reducing the probability of product damage during inspection.

[0062] It should be noted that the number of first suction cup holders 250 is not limited in this application embodiment. The number of first suction cup holders 250 can be 2 or 3. Those skilled in the art can set the number of first suction cup holders 250 according to actual needs. The second suction cup holder 260 is located among the multiple first suction cup holders 250.

[0063] It should be noted that the bottom of the first suction cup holder 250 is provided with multiple suction nozzles, and this application does not limit the number of suction nozzles on the first suction cup holder 250; the end face of the second suction cup holder 260 is provided with multiple suction nozzles, and this application does not specifically limit the number of suction nozzles on the second suction cup holder 260.

[0064] It is worth noting that the dimensional inspection equipment in this embodiment of the application also includes a frame 900, on which the feeding device 100, the conveying device 200, the first inspection table 300, the auxiliary flipping device 500, the second inspection table 600, the first inspection device 400, and the second inspection device 700 are all mounted. The feeding device 100 and the unloading device 800 are respectively located on opposite sides of the first linear drive unit 210, while the first inspection table 300, the auxiliary flipping device 500, and the second inspection table 600 are all located between the feeding device 100 and the unloading device 800. The first linear drive unit 210 drives the first mounting base 220 to reciprocate, thereby causing the first mounting base 220 to reciprocate between positions near the loading device 100 and positions near the loading device 100. This, in turn, causes the first suction cup frame 250 and the second suction cup frame 260 to move, allowing the first suction cup frame 250 to move closer to or further away from the loading device 100, the first inspection table 300, the auxiliary flipping device 500, the second inspection table 600, and the unloading device 800; and allowing the second suction cup frame 260 to move closer to or further away from the auxiliary flipping device 500. The second linear drive unit 230 drives the first support frame 240 to move up and down, thereby moving the first suction cup frame 250 and the second suction cup frame 260 to adjust their height, facilitating the first suction cup frame 250 and the second suction cup frame 260 in picking up or placing products.

[0065] Specifically, the first linear drive unit 210 and the second linear drive unit 230 can be linear drive motors.

[0066] Understandably, referring to Figure 4 The auxiliary tilting device 500 includes a support plate 510 and a vertically arranged third linear drive unit 520. The support plate 510 is slidably mounted on the third linear drive unit 520, which drives the support plate 510 to perform lifting and lowering movements. The third linear drive unit 520 can be a linear drive motor, used to drive the support plate 510 to perform lifting and lowering movements, thereby adjusting the height of the support plate 510.

[0067] Understandably, referring to Figure 4The support plate 510 has two spaced notches 511, and the second suction cup frame 260 has two spaced horizontal plates with suction nozzles on their end faces. The horizontal plates correspond one-to-one with the notches 511. Specifically, the first suction cup frame 250 places the product inspected by the first inspection device 400 onto the support plate 510. Then, through the first linear drive unit 210 and the second linear drive unit 230, the second suction cup frame 260 is positioned below the support plate 510, with the horizontal plates corresponding one-to-one with the notches 511. The second linear drive unit 230 then drives the second suction cup frame 260 to rise, allowing the suction nozzles on the horizontal plates to pick up the product. After the second linear drive unit 230 continues to drive the second suction cup frame 260 to rise to a certain height, the first rotary drive unit 270 drives the second suction cup frame 260 to rotate 180 degrees, thereby rotating the product 180 degrees. The product is then placed back onto the support plate 510, and the first suction cup frame 250 transports the rotated product to the second inspection table 600.

[0068] Understandably, referring to Figure 5 The first testing station 300 includes a first support 320 and a fourth linear drive unit 310. The fourth linear drive unit 310 is horizontally arranged, and the first support 320 is slidably mounted on the fourth linear drive unit 310. The fourth linear drive unit 310 drives the first support 320 to perform linear reciprocating motion, so that the first support 320 moves closer to or away from the transport device 200. The fourth linear drive unit 310 can be a linear drive motor, capable of driving the first support 320 closer to or away from the first linear drive unit 210 of the transport device 200. Specifically, the first linear drive unit 210 is located on one side of the fourth linear drive unit 310, while the first detection device 400 is located above the other side of the fourth linear drive unit 310. First, the fourth linear drive unit 310 drives the first placement platform to approach the first linear drive unit 210, so that the first suction cup holder 250 places the product on the first placement platform. Then, the fourth linear drive unit 310 drives the first placement platform to approach the first detection device 400, so that the first detection device 400 can detect the product on the first placement platform.

[0069] It should be noted that the direction of movement of the first linear drive unit 210 driving the first mounting base 220 is different from the direction of movement of the fourth linear drive unit 310 driving the first support platform. In one embodiment, the driving direction of the first linear drive unit 210 and the driving direction of the fourth linear drive unit 310 are perpendicular to each other.

[0070] It is worth noting that the first placement stage is equipped with a transparent acrylic panel and a backlight panel, which facilitates the first testing device 400 to test the products on the first placement stage. This application does not limit the specific structure of the first placement stage, and the art can build a corresponding first placement stage according to the actual products to be tested.

[0071] Understandably, referring to Figure 5 The second testing station 600 includes a second support 620 and a fifth linear drive unit 610. The fifth linear drive unit 610 is horizontally arranged, and the second support 620 is slidably mounted on the fifth linear drive unit 610. The fifth linear drive unit 610 drives the second support 620 to perform linear reciprocating motion, so that the second support 620 moves closer to or away from the transport device 200. The fifth linear drive unit 610 may be a linear drive motor capable of driving the second support 620 closer to or away from the transport device 200 via a first linear drive unit 210. Specifically, the first linear drive unit 210 is located on one side of the fifth linear drive unit 610, while the second detection device 700 is located above the other side of the fifth linear drive unit 610. First, the fifth linear drive unit 610 drives the second placement platform closer to the first linear drive unit 210, so that the first suction cup holder 250 places the flipped product onto the second placement platform. Then, the fifth linear drive unit 610 drives the second placement platform closer to the second detection device 700, so that the second detection device 700 can detect the product on the second placement platform.

[0072] It should be noted that the direction of movement of the first linear drive unit 210 driving the first mounting base 220 is different from the direction of movement of the fifth linear drive unit 610 driving the first support platform. In one embodiment, the driving direction of the first linear drive unit 210 and the driving direction of the fifth linear drive unit 610 are perpendicular to each other.

[0073] It is worth noting that the second placement stage is equipped with a transparent acrylic panel and a backlight panel, which facilitates the second inspection device 700 in inspecting the products on the second placement stage.

[0075] It should be noted that this application does not detect the number of the first camera 410 and the second camera 710. Those skilled in the art can set the number of the first camera 410 and the second camera 710 according to actual needs.

[0076] It is worth noting that in some embodiments, a light source assembly is also installed on the detection bracket 910. The light source assembly is used to supplement the light source for the first camera 410 or the second camera 710 so that the first camera 410 or the second camera 710 can perform detection.

[0077] Understandably, referring to Figure 7 The feeding device 100 includes a sixth linear drive unit 110 and a first storage tray 120. The sixth linear drive unit 110 is horizontally arranged, and the first storage tray 120 is slidably mounted on the sixth linear drive unit 110. The sixth linear drive unit 110 drives the first storage tray 120 to perform linear reciprocating motion. The driving direction of the sixth linear drive unit 110 can be the same as the driving direction of the fourth linear drive unit 310. A product is placed on the first storage tray 120. The sixth linear drive unit 110 drives the first storage tray 120 to perform linear reciprocating motion, thereby causing the first storage tray 120 to move closer to or further away from the first linear drive unit 210, so that the first suction cup holder 250 can pick up the product from the first storage tray 120.

[0078] In some embodiments, the number of first storage disks 120 is 2, and this application does not make a specific limitation on the number of first storage disks 120.

The seventh linear drive unit is located below the first storage tray 120 and is used to pass through the first through hole 140 to drive the first storage tray 120 to move up and down. The seventh linear drive unit is a drive cylinder, which is located below the first storage tray 120. The drive end of the drive cylinder passes through the first through hole 140, thereby pushing the product to move up and down.

[0080] Understandably, referring to Figure 8The unloading device 800 includes an eighth linear drive unit 810 and a second storage tray 820. The eighth linear drive unit 810 is horizontally arranged, and the second storage tray 820 is slidably mounted on the eighth linear drive unit 810. The eighth linear drive unit 810 drives the second storage tray 820 to perform linear reciprocating motion. The driving direction of the eighth linear drive unit 810 can be the same as the driving direction of the fifth linear drive unit 610. The second storage tray 820 is used to hold the inspected products. By being driven by the eighth linear drive unit 810 to perform linear reciprocating motion, the second storage tray 820 moves closer to or further away from the first linear drive unit 210, so that the first suction cup holder 250 can place the inspected products onto the second storage tray 820.

[0081] In some embodiments, the number of second storage disks 820 is two, one of which is used to store products that pass the test, and the other is used to store products that fail the test; this application does not make a specific limitation on the number of second storage disks 820.
