Description

Technical Field

[0001] This utility model relates to the field of product testing technology, specifically to a product testing device. Background Technology

[0002] The production process of e-ink screens involves a wide variety of testing equipment, mainly used to ensure product quality, sealing, safety, and compliance with industry standards. E-ink screens can be tested using equipment such as transmittance testers, compression testers, and CCD vision inspection. For transparent or semi-transparent e-ink screens, the uniformity of materials and impurities are tested to avoid affecting the appearance.

[0003] Modern e-ink screen production lines typically use specialized testing equipment (such as e-ink screen testing equipment) to test the screen's display performance, particle arrangement uniformity, and electric field response speed to ensure that the screen is free of ghosting and meets refresh stability standards. Testing methods include local refresh optimization, which addresses the high energy consumption problem in low-power mode by selectively refreshing key areas to reduce overall power consumption.

[0004] In most existing technologies, the production and testing of e-ink displays often requires placing the product under test into the testing equipment. Currently, the product under test is usually placed manually and then tested by the testing equipment. Since the appearance of e-ink displays is consistent, the manual placement process can easily lead to problems such as picking up or placing the wrong e-ink display, thus causing unnecessary losses to production. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a product testing device to solve the technical problem of inconsistent appearance of ink screens during production and the easy occurrence of misplacing or misplacing ink screens during manual placement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a product testing device, comprising a frame body, an infeed conveying mechanism disposed inside the frame body, a visual initial positioning mechanism disposed at the top of the infeed conveying mechanism, the visual initial positioning mechanism serving to perform visual initial positioning of the product, an infeed handling mechanism disposed inside the frame body in cooperation with the infeed conveying mechanism, the infeed handling mechanism serving to perform handling of the product, a robotic arm mechanism disposed inside the frame body, a gripping mechanism disposed at the execution end of the robotic arm mechanism, the robotic arm mechanism and the gripping mechanism serving to perform gripping and handling of the product, multiple sets of fixture detection mechanisms disposed in parallel inside the frame body, a fixture positioning vision module disposed inside the frame body above the multiple sets of fixture detection mechanisms, the fixture positioning vision module and the multiple sets of fixture detection mechanisms serving to perform positioning detection of the product.

[0007] By adopting the above technical solution, the feeding conveyor mechanism, feeding handling mechanism, robotic arm mechanism, and gripping mechanism are set up inside the main frame to cooperate with each other to achieve the function of gripping and transporting products. The feeding conveyor mechanism and feeding handling mechanism are used to feed products, and then the robotic arm mechanism and gripping mechanism cooperate to grip and place products. At the same time, the visual initial positioning mechanism, the fixture positioning vision module, and the fixture detection mechanism cooperate to achieve the function of product identification, positioning, and detection. Specifically, the visual initial positioning mechanism is used to perform preliminary positioning of the product, and then the fixture positioning vision module is used to detect and position the product.

[0008] Furthermore, the visual initial positioning mechanism consists of an ascending frame and a visual initial positioning module. The ascending frame located above the feeding conveying mechanism is fixedly connected to the top of the main frame. The visual initial positioning module that cooperates with the feeding conveying mechanism is set inside the ascending frame. The fixture positioning vision module consists of a moving platform, a second guide rail, and a fixture positioning vision module. The second guide rail is fixedly connected to the top of the main frame. The moving platform is movably connected to the top of the second guide rail. The fixture positioning vision module that cooperates with the fixture detection mechanism is set inside the moving platform.

[0009] By adopting the above technical solution, the product is initially positioned and further precisely positioned using the visual initial positioning module and the fixture positioning visual module, thereby achieving the effect of multiple positioning of the product and ensuring that the product is placed in an accurate position.

[0010] Furthermore, the robotic arm mechanism consists of a robotic arm body, a connecting arm, a control module, and a first guide rail. The first guide rail is fixedly connected to the top of the frame body, and the control module is slidably connected to the surface of the first guide rail. The robotic arm body is disposed at the top of the control module, and the robotic arm body and the control module are movably connected through the connecting arm.

[0011] By adopting the above technical solution, the robotic arm mechanism clamps and transports products within the feeding and handling mechanism. Specifically, the main body of the robotic arm grips and fixes the product through a gripping mechanism at one end. Then, through a structure in which the robotic arm is movably connected to the control module via a connecting arm, the main body of the robotic arm can rotate horizontally and adjust its angle. At the same time, through a structure in which the control module slides inside the first guide rail, the main body of the robotic arm can move laterally, thereby increasing the overall gripping range of the robotic arm mechanism.

[0012] Furthermore, the gripping mechanism consists of a loading / unloading suction cup module, a gripping control module, and a gripping connection module. The gripping connection module is movably connected to the bottom of the robotic arm body. One end of the gripping connection module is movably connected to the gripping control module, and the bottom of the gripping control module is provided with two sets of loading / unloading suction cup modules.

[0013] By adopting the above technical solution, the gripping control module uses the loading and unloading suction cup module at its bottom to adsorb and grip the two sets of products, and the gripping connection module fixes the gripping mechanism to the main body of the robotic arm. The loading and unloading suction cup module can change the gripping range according to different product specifications.

[0014] Furthermore, the fixture testing mechanism consists of a fixture testing platform, a pressing cylinder, a probe indenter, and a test plate. Multiple sets of fixture testing platforms are arranged inside the frame body. A pressing cylinder is arranged at the top of each set of fixture testing platforms. A probe indenter that cooperates with the fixture testing platform is arranged at the bottom of the pressing cylinder. Multiple sets of test plates that are electrically connected to the probe indenter are arranged inside the frame body.

[0015] By adopting the above technical solution, the robotic arm mechanism carries the material to the top of the fixture positioning vision module to take pictures. Then, the AOI slide table carries the fixture positioning vision module to the top of the fixture to take pictures of the Mark points on the fixture. The results of the two cameras are processed by vision software and fed back to the robotic arm mechanism. The robotic arm mechanism carries the material to the fixture probe head and places it to be lit. After the product is positioned, the pressing cylinder presses downward, thereby pressing down and energizing the probe head. When the probe head contacts the fixture detection platform, the pressing cylinder stops pressing. The product is detected by the fixture brush screen and A inside the fixture detection platform.

[0016] Furthermore, the main frame body is equipped with a material discharge conveying mechanism that cooperates with the robotic arm mechanism. Both the material feeding conveying mechanism and the material discharge conveying mechanism adopt two sets of synchronous conveyor belts.

[0017] By adopting the above technical solution, the loading and unloading suction cup module can use its two sets of suction cups to adsorb and grab different products, and then rotate them horizontally through the gripping control module, thereby exchanging the positions of the two sets of products. Finally, qualified and unqualified products are placed on the surfaces of two different conveyor belts in the discharge conveying mechanism, thus playing a role in product screening.

[0018] The frame body (1) is provided with multiple sets of protective plates (10). The protective plates (10) are provided with inlet and outlet windows (11) that cooperate with the feeding conveyor (2) and the discharging conveyor (3).

[0035] The frame body 1 is equipped with a feeding and conveying mechanism 9 that cooperates with the feeding and conveying mechanism 2, and the feeding and conveying mechanism 9 is used to transport products. The frame body 1 also has a robotic arm mechanism 5, with a gripping mechanism 8 at its execution end. The robotic arm mechanism 5 and the gripping mechanism 8 are used to grip and transport products. Multiple sets of fixture inspection mechanisms 7 are arranged in parallel inside the frame body 1. A fixture positioning vision module 6 is located above the multiple sets of fixture inspection mechanisms 7 inside the frame body 1. The fixture positioning vision module 6 and the multiple sets of fixture inspection mechanisms 7 are used to perform positioning and inspection of the products. The feeding and conveying mechanism 2, feeding and conveying mechanism 9, and the feeding and conveying mechanism 9 are used to transport products. The material handling mechanism 9, the robotic arm mechanism 5, and the gripping mechanism 8 work together to grasp and transport the product. Specifically, the feeding conveyor mechanism 2 and the feeding handling mechanism 9 feed the product, and then the robotic arm mechanism 5 and the gripping mechanism 8 work together to grasp and place the product. At the same time, the visual initial positioning mechanism 4, the fixture positioning vision module 6, and the fixture detection mechanism 7 work together to identify, locate, and detect the product. Specifically, the visual initial positioning mechanism 4 performs initial positioning of the product, and then the fixture positioning vision module 6 performs detection and positioning of the product.

[0036] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 The visual initial positioning mechanism 4 consists of an ascending frame 401 and a visual initial positioning module 402. The ascending frame 401, located above the feeding conveyor mechanism 2, is fixedly connected to the top of the frame body 1.

The feeding conveyor 2 moves the product to the side of the feeding and handling mechanism 9 through two sets of conveyor belts. At the same time, the visual initial positioning module 402 performs preliminary positioning of the product. Meanwhile, the robotic arm mechanism 5 carries the material to the fixture positioning vision module 803 to take pictures. Then, the AOI slide table carries the fixture positioning vision module 6 to the top of the fixture to take pictures of the Mark points on the fixture. The results of the two cameras are processed jointly by the vision software.

[0037] Please see Figure 2 and Figure 7The robotic arm mechanism 5 consists of a robotic arm body 501, a connecting arm 502, a control module 503, and a first guide rail 504. The first guide rail 504 is fixedly connected to the top of the frame body 1, and the control module 503 is slidably connected to the surface of the first guide rail 504. The robotic arm body 501 is set at the top of the control module 503. The robotic arm body 501 and the control module 503 are movably connected through the connecting arm 502. The robotic arm mechanism 5 clamps and transports the products in the feeding and handling mechanism 9. Specifically, the robotic arm body 501 grips and fixes the products through the gripping mechanism 8 set at one end. Then, the robotic arm body 501 is movably connected to the control module 503 through the connecting arm 502, which enables the robotic arm body 501 to rotate horizontally and adjust its angle. At the same time, the control module 503 slides inside the first guide rail 504, which facilitates the lateral movement of the robotic arm body 501, thereby increasing the overall gripping range of the robotic arm mechanism 5.

[0038] Please see Figure 8 The gripping mechanism 8 consists of a loading / unloading suction cup module 801, a gripping control module 803, and a gripping connection module 804. The gripping connection module 804 is movably connected to the bottom of the robotic arm body 501. One end of the gripping connection module 804 is movably connected to the gripping control module 803. The bottom of the gripping control module 803 is provided with two sets of loading / unloading suction cup modules 801. The gripping control module 803 uses the loading / unloading suction cup modules 801 at its bottom to perform adsorption and gripping of two sets of products. The gripping connection module 804 fixes the gripping mechanism 8 to the robotic arm body 501. The loading / unloading suction cup modules 801 can change the gripping range according to different product specifications.

[0039] Please see Figure 9The fixture inspection mechanism 7 consists of a fixture inspection platform 701, a pressing cylinder 702, a probe indenter 703, and a test plate 704. Multiple sets of fixture inspection platforms 701 are installed inside the frame body 1. A pressing cylinder 702 is installed at the top of each fixture inspection platform 701, and a probe indenter 703 that cooperates with the fixture inspection platform 701 is installed at the bottom of each pressing cylinder 702. Multiple sets of test plates 704, electrically connected to the probe indenters 703, are installed inside the frame body 1. The product is positioned using a fixture positioning vision module 603 installed at the top of the fixture inspection platform 701. Specifically, the robotic arm mechanism 5 brings the material to the fixture. The positioning vision module 803 takes a picture from above, and then the AOI slide table with fixture positioning vision module 6 moves above the fixture to take pictures of the Mark points on the fixture. The results of the two cameras are processed by vision software and fed back to the robotic arm mechanism 5. The robotic arm mechanism 5 carries the material to the fixture probe pressure head 703 and places it there. After the product is positioned, the pressing cylinder 702 presses downward, which in turn presses down and powers on the probe pressure head 703. When the probe pressure head 703 contacts the fixture detection platform 701, the pressing cylinder 702 stops pressing. The product is then inspected by the fixture brush screen and AO1 set inside the fixture detection platform 701.

[0040] The working principle of this utility model is as follows: When in use, the power is turned on and the user places the product on the surface of the feeding conveyor 2. At this time, the feeding conveyor 2 moves the product to the side of the feeding and handling mechanism 9 through two sets of conveyor belts. At the same time, the visual initial positioning module 402 performs initial positioning of the product, thereby facilitating the feeding and handling mechanism 9 to handle the product.

[0041] During use, the robotic arm mechanism 5 clamps and transports the products in the feeding and handling mechanism 9. Specifically, the robotic arm body 501 grips and fixes the products through the gripping mechanism 8 at one end. Then, the robotic arm body 501 is movably connected to the control module 503 through the connecting arm 502, which enables the robotic arm body 501 to rotate horizontally and adjust its angle. At the same time, the control module 503 slides inside the first guide rail 504, which facilitates the lateral movement of the robotic arm body 501, thereby increasing the overall gripping range of the robotic arm mechanism 5.

[0042] At the same time, the gripping control module 803 uses the loading and unloading suction cup module 801 at its bottom to grip the two sets of products, and uses the gripping connection module 804 to fix the gripping mechanism 8 to the robotic arm body 501. The loading and unloading suction cup module 801 can change the gripping range according to different product specifications.

[0043] During use, the robotic arm mechanism 5 places two sets of products on the surface of the fixture inspection platform 701 through the gripping mechanism 8. At this time, the fixture positioning vision module 603 set at the top of the fixture inspection platform 701 positions the products. Specifically, the robotic arm mechanism 5 carries the material to the fixture positioning vision module 803 to take pictures. Then, the AOI slide table carries the fixture positioning vision module 603 to the top of the fixture to take pictures of the Mark points on the fixture. The results of the two cameras are processed by vision software and fed back to the robotic arm mechanism 5. The robotic arm mechanism 5 carries the material to the fixture probe pressure head 703 and places it to light up. After the product positioning is completed, the pressing cylinder 702 presses downward, thereby pressing down and energizing the probe pressure head 703. When the probe pressure head 703 contacts the fixture inspection platform 701, the pressing cylinder 702 stops pressing. The product is inspected through the fixture brush screen and AO1 set inside the fixture inspection platform 701.

[0044] During use, after the product inspection is completed, the gripping mechanism 8 simultaneously grips two sets of products through the loading and unloading suction cup module 801 and transports them to the surface of the discharge conveying mechanism 3 through the robotic arm mechanism 5. Specifically, the loading and unloading suction cup module 801 can use its two sets of suction cups to adsorb and grip different products, and then rotates horizontally through the gripping control module 803, thereby exchanging the positions of the two sets of products. Finally, qualified and unqualified products are placed on the surfaces of two different conveyor belts in the discharge conveying mechanism 3, thereby playing the role of product screening.
