Description

Technical Field

[0001] The present invention relates to the technical field of product testing, and specifically provides a product testing device. Background Art

[0002] There are a wide variety of detection devices involved in the production process of ink screens, mainly used to ensure product quality, sealing performance, safety, and compliance with industry standards. Ink screens can be detected by detection devices such as light transmittance testers, compressive testing machines, and CCD vision detection. For transparent or semi-transparent ink screens, the material uniformity and impurities are detected to avoid affecting the appearance.

[0003] Modern ink screen production lines usually test the display performance, particle arrangement uniformity, and electric field response speed of the screen through dedicated detection devices (such as electronic ink screen detection devices) to ensure that there are no afterimages on the screen and the refresh stability meets the standard. The detection methods include local refresh optimization. To address the high energy consumption problem in the low-power mode, the overall power consumption is reduced by selectively refreshing key areas.

[0004] In most existing ink screen production tests, the product to be tested often needs to be placed in the test device for testing. Currently, the product to be tested is generally placed manually and then tested by the test device. Since the appearance of ink screens in production is the same, problems such as misplacing or wrongly placing the ink screen are likely to occur during the manual placement process, resulting in unnecessary losses to production. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a product testing device to solve the technical problem that since the appearance of ink screens in production is the same, it is easy to misplace or wrongly place the ink screen during the manual placement process.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A product testing device includes a frame main body. Inside the frame main body, a feeding conveying mechanism is arranged. At the top of the feeding conveying mechanism, a visual initial positioning mechanism is arranged, and the visual initial positioning mechanism plays a role in visually initially positioning the product. Inside the frame main body, a feeding handling mechanism is arranged in cooperation with the feeding conveying mechanism, and the feeding handling mechanism plays a role in handling the product. Inside the frame main body, a robotic arm mechanism is arranged. At the execution end of the robotic arm mechanism, a grasping mechanism is arranged, and the robotic arm mechanism and the grasping mechanism play a role in grasping and handling the product. Inside the frame main body, multiple groups of fixture detection mechanisms are arranged in parallel. Inside the frame main body, a fixture positioning vision module is arranged above the multiple groups of fixture detection mechanisms, and the fixture positioning vision module and the multiple groups of fixture detection mechanisms play a role in positioning and detecting the product.

[0007] By adopting the above technical solution, through the mutual cooperation of the feeding conveying mechanism, the feeding handling mechanism, the robotic arm mechanism and the grasping mechanism inside the frame body, the function of grasping and transporting the product is achieved. The feeding conveying mechanism and the feeding handling mechanism are used to feed the product, and then the robotic arm mechanism and the grasping mechanism cooperate with each other to achieve the function of grasping and placing the product. At the same time, through the mutual cooperation of the visual preliminary positioning mechanism, the fixture positioning vision module and the fixture detection mechanism, the functions of identifying and positioning the product and detecting the product are achieved. Specifically, the visual preliminary positioning mechanism is used to preliminarily position the product, and then the fixture positioning vision module is used to detect and position the product.

[0008] Further, the visual preliminary positioning mechanism is composed of a heightening frame and a visual preliminary positioning module. The heightening frame is fixedly connected to the top end of the frame body and is located above the feeding conveying mechanism. The visual preliminary positioning module is arranged inside the heightening frame and is matched with the feeding conveying mechanism. The fixture positioning vision module is composed of a moving platform, a second guide rail and a fixture positioning vision module. The second guide rail is fixedly connected to the top end of the frame body. The moving platform is movably connected to the top end of the second guide rail. The fixture positioning vision module is arranged inside the moving platform and is matched with the fixture detection mechanism.

[0009] By adopting the above technical solution, the visual preliminary positioning module and the fixture positioning vision module are used to preliminarily position and further accurately position the product, so as to achieve the function of positioning the product multiple times, thereby achieving the effect of accurately placing the product.

[0010] Further, the robotic arm mechanism is composed of a robotic arm main body, a connecting arm, a control module and a first guide rail. The first guide rail is fixedly connected to the top end of the frame body. The control module is slidably connected to the surface of the first guide rail. The robotic arm main body is arranged at the top end of the control module. The robotic arm main 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 the product in the feeding handling mechanism. Specifically, the robotic arm main body grasps and fixes the product through the grasping mechanism arranged at one end thereof, and then the robotic arm main body, through the structure of being movably connected to the control module through the connecting arm, achieves the function of horizontally rotating and adjusting the angle of the robotic arm main body. At the same time, through the structure of the control module sliding inside the first guide rail, the function of facilitating the lateral movement of the robotic arm main body is achieved, thereby achieving the effect of increasing the overall grasping range of the robotic arm mechanism.

[0012] Further, the grasping mechanism is composed of a loading and unloading suction cup module, a grasping control module, and a grasping connection module. The grasping connection module is movably connected to the bottom of the robotic arm main body. One end of the grasping connection module is movably connected to the grasping control module, and two groups of loading and unloading suction cup modules are arranged at the bottom of the grasping control module.

[0013] By adopting the above technical solution, the grasping control module uses the loading and unloading suction cup module arranged at its bottom end to adsorb and grasp two groups of products, and the grasping mechanism is fixedly connected to the robotic arm main body through the grasping connection module. Among them, the loading and unloading suction cup module can change the grasping range according to products of different specifications.

[0014] Further, the fixture detection mechanism is composed of a fixture detection platform, a pressing cylinder, a probe head, and a test board. Multiple groups of fixture detection platforms are arranged inside the frame main body. Pressing cylinders are arranged at the tops of the multiple groups of fixture detection platforms. The bottom end of the pressing cylinder is provided with a probe head that cooperates with the fixture detection platform. Multiple groups of test boards electrically connected to the probe head are arranged inside the frame main body.

[0015] By adopting the above technical solution, the robotic arm mechanism takes the material to the position above the fixture positioning vision module for photographing. Then, the AOI slide table takes the fixture positioning vision module to the position above the fixture to photograph the Mark points on the fixture. The shooting results of the two cameras are jointly processed by the vision software, and the results are fed back to the robotic arm mechanism. The robotic arm mechanism takes the material to the position of the fixture probe head and places it to light up. When the product is positioned and placed, at this time, the pressing cylinder presses downward, so that the probe head presses down and powers on. When the probe head contacts the fixture detection platform, the pressing cylinder stops pressing, and the product is detected through the fixture brush screen and A arranged inside the fixture detection platform.

[0016] Further, a discharging conveying mechanism that cooperates with the robotic arm mechanism is arranged inside the frame main body. Both the feeding conveying mechanism and the discharging conveying mechanism adopt two groups of synchronous conveyor belts.

[0017] By adopting the above technical solution, the loading and unloading suction cup module can adsorb and grasp different products through the two suction cups it sets, and then horizontally rotate through the grasping control module, so that the two groups of products are interchanged in position. Finally, the qualified and unqualified products are respectively placed on the surfaces of the two different conveyor belts in the discharging conveying mechanism, so as to play a role in screening the products.

[0018] In summary, the present invention mainly has the following beneficial effects: By arranging a feeding and conveying mechanism, a feeding handling mechanism, a robotic arm mechanism, and a grasping mechanism inside the frame body to cooperate with each other, the present invention achieves the function of grasping and transporting products. Specifically, the feeding and conveying mechanism and the feeding handling mechanism are used to feed the products, and then the robotic arm mechanism and the grasping mechanism cooperate with each other to achieve the function of grasping and placing the products. At the same time, by arranging a visual preliminary positioning mechanism, a fixture positioning vision module, and a fixture detection mechanism to cooperate with each other, the present invention achieves the functions of identifying and positioning the products and detecting the products. Specifically, the visual preliminary positioning mechanism is used to preliminarily position the products, and then the fixture positioning vision module is used to detect and position the products.

Among them, the products in the feeding and handling mechanism 9 are clamped and handled by the robotic arm mechanism 5. Specifically, the robotic arm main body 501 grabs and fixes the products through the grasping mechanism 8 provided at one end thereof. Then, the robotic arm main body 501 is movably connected with the control module 503 through the connecting arm 502, so as to achieve the effect of enabling the robotic arm main body 501 to rotate horizontally and adjust the angle. At the same time, through the structure that the control module 503 slides inside the first guide rail 504, the effect of facilitating the lateral movement of the robotic arm main body 501 is achieved, thereby increasing the overall grasping range of the robotic arm mechanism 5.

[0035] Please refer to Figure 8 , the grasping mechanism 8 is composed of a loading and unloading suction cup module 801, a grasping control module 803 and a grasping connection module 804.

Specifically, the robotic arm mechanism 5 brings the material to take pictures above the fixture positioning vision module 803, and then the AOI slide table brings the fixture positioning vision module 6 to take pictures of the Mark points on the fixture above the fixture. The shooting results of the two cameras are jointly processed by the vision software, and the results are fed back to the robotic arm mechanism 5.

[0037] The working principle of the present invention is as follows: When in use, the power is turned on, and the user places the product on the surface of the feeding conveyor mechanism 2. At this time, the feeding conveyor mechanism 2 moves the product to one side of the feeding handling mechanism 9 through two conveyor belts, and at the same time, the product is preliminarily positioned through the vision preliminary positioning module 402, so as to facilitate the feeding handling mechanism 9 to handle the product;

[0038] During the use process, the product in the feeding handling mechanism 9 is clamped and handled by the robotic arm mechanism 5. Specifically, the robotic arm main body 501 grabs and fixes the product through the grabbing mechanism 8 arranged at one end thereof, and then the robotic arm main body 501 is movably connected to the control module 503 through the connecting arm 502, so as to achieve the effect of making the robotic arm main body 501 rotate horizontally and adjust the angle.

Specifically, the robotic arm mechanism 5 brings the materials to take pictures above the fixture positioning vision module 803. Then, the AOI slide table brings the fixture positioning vision module 6 to take pictures of the Mark points on the fixture above the fixture. The shooting results of the two cameras are jointly processed by the vision software, and the results are fed back to the robotic arm mechanism 5. The robotic arm mechanism 5 brings the materials to the fixture probe head 703 to place and light them. When the product positioning and placement are completed, the pressing cylinder 702 presses downwards at this time, so that the probe head 703 presses down and powers on. When the probe head 703 contacts the fixture detection platform 701, the pressing cylinder 702 stops pressing, and the products are detected through the fixture brush screen and A01 provided inside the fixture detection platform 701;

[0041] During use, after the product detection is completed, the grasping mechanism 8 simultaneously grabs two sets of products through the loading and unloading suction cup module 801 and transports them to the surface of the discharging conveying mechanism 3 through the robotic arm mechanism 5. Specifically, the loading and unloading suction cup module 801 can adsorb and grab different products through the two sets of suction cups provided thereon, and then horizontally rotate through the grasping control module 803, so that the two sets of products are interchanged in position. Finally, the qualified and unqualified products are respectively placed on the surfaces of two different conveyor belts in the discharging conveying mechanism 3, so as to play a role in screening the products.
