Description

Technical Field

[0001] This utility model relates to the field of screen panel technology, and in particular to a flexible plug-in mechanism for a module screen. Background Technology

[0002] Modular screens refer to LED, LCD, or liquid crystal display screens and circuit board components. After the screen panel is manufactured, it needs to undergo a full inspection process before the product can move to the next process. Because it is a full inspection, the workload is huge and the accuracy requirements of the inspection are very high. In the production of modular screens, the wires need to be plugged into the interfaces on the modular screen. Since the interface is located near the edge of the modular screen and the interface direction is towards the center of the modular screen, the current production method is to manually insert the test wires into the interfaces on the modular screen at the workstation for testing. This is inefficient, and some wires are small in size and are difficult to plug into the positions on the modular screen, which affects production efficiency. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a flexible plug-in mechanism for module screens, which can improve the production efficiency of customers.

[0004] To solve the above-mentioned technical problems, the present invention provides a module screen elastic plug-in mechanism, including at least one set of three-axis drive structures. The upper end of the three-axis drive structure is fixedly installed with a plug-in structure for moving the plug-in structure in the X, Y, and Z directions. The plug-in structure includes a frame unit and a plug-in unit. The plug-in unit is installed on the frame unit. A test cable is fixed at the upper end of the plug-in unit. The test cable of the three-axis drive structure is plugged into the interface of the module screen back panel.

[0005] The insertion unit includes a base plate and a mounting portion disposed on the outer end of the base plate, with a test cable mounted on the upper end of the mounting portion. It also includes a height adjustment component movably mounted on the outer end of the base plate for adjusting the insertion height of the test cable. This application allows the test cable to be mounted on the upper end of the insertion unit. With the back panel of the module screen facing downwards, the insertion unit is moved by a moving frame unit to allow the test cable to be inserted into the connector on the back panel of the module screen for testing. This solves the problem of existing manual insertion methods and improves customer production efficiency and yield.

[0006] The frame unit includes a base, a fixed plate, and a sliding plate. The fixed plate is vertically fixed to the base, and the sliding plate is connected to the fixed plate through a guide assembly, so that the sliding plate reciprocates along the direction of the guide assembly.

[0007] An elastic component is installed between the lower end of the moving plate and the base. This application has an elastic component that acts as a buffer to prevent the test cable from damaging the product during insertion when the moving plate moves upward.

[0008] The guiding component includes a guide recess fixedly installed on the side of the fixed plate and a linear rail fixedly installed on the side of the moving plate. The linear rail is matched and installed with the guide recess and slides within the guide recess. The combination of the guiding component and the elastic component in this application ensures that the moving plate will not deviate from its direction during lifting and lowering, maintaining vertical lifting and lowering. When the test cable is plugged into the interface on the back panel of the module screen, it ensures correct plugging position and prevents damage to the product during plugging.

[0009] The height adjustment component is connected to the base plate via an inclined surface. The insertion height of the test cable 3 can be adjusted by changing the contact area between the height adjustment component and the base plate.

[0010] The height adjustment component includes an adjustment block, the lower end surface of which is inclined, and a stop extending downward from the lower outer edge of the adjustment block. This height adjustment component is used to test the distance between the test cable and the module screen back panel, ensuring that the test cable can be smoothly plugged into the interface on the module screen back panel.

[0011] The mounting part protrudes from the upper surface of the base plate, and the inclined surfaces of the base plate and the height adjustment component are at least located on one side of the mounting part.

[0012] The base plate has a through hole located below the test cable. The plug-in assembly of this application, combined with a positioning vision structure, positions the interface on the back panel of the module screen. By moving the frame unit, the test cable is moved to the plug-in position and smoothly plugged into the interface on the back panel of the module screen.

[0013] At least one guide bearing is provided on the adjusting block. The beneficial effects of this utility model are: The modular screen elastic plug-in mechanism of this utility model installs the test wire at the upper end of the plug-in unit, places the module screen with the back plate facing down, and drives the plug-in unit to plug the test wire into the socket on the module screen back plate for testing by moving the frame unit. This solves the problem of the existing manual plug-in method and improves the customer's production efficiency and yield. Attached Figure Description

[0016] Please see Figure 1-4 The embodiments of this utility model include: A modular screen elastic plug-in mechanism includes any of the plug-in structures described above, and further includes a three-axis drive structure 4. The upper end of the three-axis drive structure is fixedly installed with the plug-in structure, which is used to move the plug-in structure in the X, Y, and Z directions to plug the test wire into the modular screen.

[0017] Specifically, the three-axis drive structure 4 includes a Y-axis driver 41, an X-axis driver 42, and a Z-axis driver 43. The X-axis driver is mounted on the mover of the Y-axis driver, the Z-axis driver is mounted on the mover of the X-axis driver, and the lifting end of the Z-axis driver is mounted on a base 11.

[0018] More specifically, depending on customer needs, the module screen back panel has multiple interfaces and multiple plug-in mechanisms can be installed. The plug-in components of the plug-in mechanism can be equipped with the same test cables or different test cables.

[0019] A frame unit 1 is used to fix the plug-in unit 2, so that the plug-in unit 2 is installed on the upper end of the frame unit 1; The insertion unit 2 includes a base plate 21 and a mounting portion 211 disposed on the outer end of the base plate 21. A test cable 3 is mounted on the upper end of the mounting portion 211. It also includes a height adjustment component 22 movably mounted on the outer end of the base plate 2 for adjusting the insertion height of the test cable 3. This application allows the test cable to be mounted on the upper end of the insertion unit. With the back panel of the module screen facing down, the insertion unit is moved by the moving frame unit to allow the test cable to be inserted into the connector on the back panel of the module screen for testing. This solves the problem of existing manual insertion methods and improves customer production efficiency and yield.

[0020] The frame unit 1 includes a base 11, a fixed plate 12, and a sliding plate 13. The fixed plate 12 is vertically fixed to the base 11, and the sliding plate 13 is connected to the fixed plate 12 through a guide assembly 14, so that the sliding plate 13 reciprocates along the direction of the guide assembly 14.

[0021] An elastic component 15 is installed between the lower end of the sliding plate 13 and the base 11. This application has an elastic component that acts as a buffer to prevent the test cable from damaging the product during insertion when the sliding plate moves upward. Specifically, the elastic component is a spring or the like.

[0022] More specifically, a sensor can also be installed between the lower end of the shift plate 13 and the base. When the spring is damaged or over-pressured, the sensor will issue a warning and stop the plug-in structure from operating, ensuring the safety of the module screen.

[0023] The guide assembly 14 includes a guide recess 141 fixedly installed on the side of the fixed plate 12 and a linear guide 142 fixedly installed on the side of the moving plate 13. The linear guide 142 is matched and installed with the guide recess 141 and slides within the guide recess 141. The guide assembly and elastic assembly of this application are used in combination to ensure that the moving plate does not deviate from its direction during lifting and lowering, always maintaining vertical lifting and lowering. When the test cable is plugged into the interface on the back panel of the module screen, the plugging position is ensured to be correct, preventing damage to the product during plugging.

[0024] The height adjustment component 22 is connected to the base plate 21 via an inclined surface. The insertion height of the test cable 3 can be adjusted by changing the contact area between the height adjustment component 22 and the base plate 21.

[0025] The height adjustment component 22 includes an adjustment block 221. The lower end surface of the adjustment block 221 is an inclined surface, and the lower outer edge of the adjustment block 221 extends downward to form a stop. This height adjustment component is used to test the distance between the test cable and the module screen back panel, ensuring that the test cable can be smoothly plugged into the interface on the module screen back panel. Specifically, the stop is provided with an adjustment waist hole, and the outer end surface of the base plate is provided with a threaded hole corresponding to the adjustment waist hole. An adjustment screw passes through the adjustment waist hole and is threadedly connected to the threaded hole.

[0026] The mounting portion 211 protrudes from the upper surface of the base plate 21, and the inclined surfaces of the base plate 21 and the height adjustment component 22 are at least located on one side of the mounting portion 211. Specifically, after the test cable is placed on the mounting portion 211, it is fixed by the cover plate 212. The cover plate 212 and the mounting portion 211 are respectively provided with mounting holes, and the test cable is fixed between the mounting portion 211 and the cover plate 212 by screws in the mounting holes. In specific implementations of this application, different test cables can be selected to be placed between the mounting portion and the cover plate according to the needs of the implementing customer, without changing other structures, to adapt to different module screens.

[0027] The base plate 21 has a through hole 23 located below the test cable 3. The plug-in assembly of this application, combined with the positioning vision structure 5, positions the interface on the back panel of the module screen. By moving the frame unit, the test cable is moved to the plug-in position and smoothly plugged into the interface on the back panel of the module screen. Specifically, the positioning vision structure includes a CCD and a light source.

[0028] At least one guide bearing 222 is provided on the adjusting block 221. Specifically, two guide bearings are provided on the adjusting block, respectively located on both sides of the mounting portion. The guide in this application allows the plug-in structure to move along the back plate to the plug-in position of the interface, serving a guiding and positioning function.

[0029] The working process of the elastic plug-in mechanism for a module screen according to this utility model is as follows: 1. First, fix the test cable between the mounting part and the cover plate; 2. Based on the interface position of the module screen back panel, initially adjust the Y-axis driver, X-axis driver and Z-axis driver to bring the test cable close to the interface and the guide bearing to contact the module screen back panel; 3. After the CCD performs visual positioning of the insertion position, the test cables of the Y-axis driver, X-axis driver and Z-axis driver are moved to the interface insertion position for insertion.
