Description

Technical Field

[0001] This utility model relates to the field of glass panel testing technology, specifically to an automatic assembly equipment for testing fixtures. Background Technology

[0002] Electrical testing of screen glass panels mainly includes current and voltage testing, capacitance testing, and time response testing. These tests generally require connecting different devices to the electrodes of the panel to achieve the measurement objectives.

[0003] During the testing process, due to the diversity of equipment, the connection of electrodes needs to be disassembled and reassembled for each test, which is inconvenient. Therefore, the emergence of connection fixtures can enable multiple testing procedures to be completed with a single connection.

[0004] Existing connection fixtures are all integral structures, requiring a separate fixture for each size and model of screen glass panel, resulting in high fixture usage costs. Our company has discovered through research that by separating the universal and non-universal parts of the connection fixture, only the non-universal part needs to be replaced when testing screen glass panels of different sizes and models, thus reducing usage costs.

[0005] The jigs with the aforementioned disassembled structure are extremely time-consuming and labor-intensive to replace and assemble, therefore it is essential to develop a device for automatically assembling jigs. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide an automatic assembly equipment for testing fixtures, which can automatically replace non-standard fixture parts, improve replacement efficiency, and achieve high contact alignment accuracy during replacement.

[0007] To solve the above-mentioned technical problems, this utility model provides an automatic assembly equipment for testing fixtures, including an upper top plate and an upper fixture and a lower fixture designed to be split. The bottom of both sides of the upper top plate is provided with a side mounting plate. The bottom of the side mounting plate is provided with a horizontal support plate and cooperates to form an L-shaped base. The two L-shaped bases are arranged opposite to each other and cooperate to form a lifting frame. A limit protrusion is provided on one end surface of the horizontal support plate. An avoidance opening is provided in the middle of the upper top plate.

[0008] Both side mounting plates are equipped with positioning modules, which cooperate with the limiting protrusions to limit and fix one side of the lower fixture to the horizontal support plate.

[0009] The upper top plate is also equipped with two lateral assembly cylinders and one intermediate assembly cylinder. The lateral assembly cylinders and the intermediate assembly cylinder are connected to the upper fixture and operate synchronously. The lateral assembly cylinders and the intermediate assembly cylinder cooperate to assemble or separate the upper fixture from the lower fixture.

[0010] Furthermore, the limiting protrusion is a guide wheel, and a limiting groove is provided on the side of the lower fixture corresponding to the guide wheel.

[0011] Furthermore, the positioning module includes a front positioning component and an end positioning component, which are used to limit and fix the corresponding corners of the lower fixture.

[0012] Furthermore, the head positioning component includes a first Z-axis clamping cylinder and a first X-axis clamping cylinder. The first Z-axis clamping cylinder is provided with a flat clamping block, and the first X-axis clamping cylinder is provided with an L-shaped horizontal clamping block. The first X-axis clamping cylinder is also connected to a first Y-axis clamping cylinder, and the first Y-axis clamping cylinder drives the first X-axis clamping cylinder to move along the Y-axis direction.

[0013] Furthermore, the end positioning component includes a second Z-axis clamping cylinder and a second Y-axis clamping cylinder. The second Z-axis clamping cylinder is provided with an L-shaped vertical clamping block, and the second Y-axis clamping cylinder is provided with a flat clamping block.

[0014] Furthermore, the positioning module also includes a third Z-axis clamping cylinder, which is equipped with a power supply connector.

[0015] Furthermore, both the lateral assembly cylinder and the intermediate assembly cylinder are fixedly connected to the upper top plate via cantilever brackets. The lateral assembly cylinder is equipped with a lifting connecting plate, which is locked to the side frame of the upper fixture. A guide rail is also provided between the lifting plate and the lateral mounting plate. The intermediate assembly cylinder is equipped with a gantry, which is fixedly connected to the two sides of the upper fixture.

[0016] Furthermore, handles are provided on the outer periphery of both the upper fixture and the upper top plate.

[0017] The beneficial effects of this utility model are:

[0018] 1. By dividing the testing fixture into two modules, one set consists of general-purpose components and the other set consists of non-general-purpose components that need to be replaced according to the size and model of the screen glass panel. The electrical connection between the general-purpose and non-general-purpose components adopts a unified adapter specification, so that the general-purpose components do not need to be replaced, only the non-general-purpose components need to be replaced. Some circuit boards and electrical components in the general-purpose components can be retained, which greatly reduces the cost of using the mold.

[0019] 2. During the assembly process, the positioning module can effectively position the lower fixture. By lowering the upper fixture, which is fixed in a horizontal position, the assembly can be quickly and accurately aligned without manual intervention, greatly improving the efficiency and accuracy of fixture assembly.

[0020] 3. The design of the lifting frame ensures that the lower fixture is positioned without affecting the use of the bottom space. The product can be directly attached to the detection position at the bottom of the lower fixture, resulting in high stability. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1 to 5 As shown, an embodiment of the automatic assembly equipment for testing fixtures of this utility model includes an upper top plate 1 and an upper fixture 2 and a lower fixture 3 with a split design. Side mounting plates 4 are provided on both sides of the bottom of the upper top plate. Horizontal support plates 5 are provided at the bottom of the side mounting plates and cooperate to form an L-shaped base 6. The two L-shaped bases are arranged opposite each other and cooperate to form a lifting frame. A limiting protrusion 7 is provided on one end surface of the horizontal support plate, and an avoidance opening 8 is provided in the middle of the upper top plate.

[0028] Both side mounting plates are equipped with positioning modules 9. The positioning modules cooperate with the limiting protrusions to limit and fix one side of the lower fixture to the horizontal support plate.

[0029] The upper plate is also equipped with two lateral assembly cylinders 10 and one intermediate assembly cylinder 11. Both the lateral assembly cylinders and the intermediate assembly cylinder are connected to the upper fixture and operate synchronously. The lateral assembly cylinders and the intermediate assembly cylinder work together to assemble or separate the upper fixture from the lower fixture.

[0030] The upper fixture mentioned above does not require disassembly or reassembly for different sized products after installation. Therefore, during equipment debugging, the upper fixture is installed first, followed by the lower fixture based on its position, ensuring they are assembled together. Then, the strokes of the positioning module, side assembly cylinder, and intermediate assembly cylinder are effectively calibrated to fix the relative positions of the upper and lower fixtures. Once calibration is complete, the equipment can be used normally.

[0031] During use, the upper fixture is always fixedly mounted on two lateral assembly cylinders and one intermediate assembly cylinder. The lower fixture is inserted and placed by a robot or a transport structure from the side of the hoisting frame away from the limiting protrusion. During the lateral placement process, the lower fixture will be blocked by the limiting protrusion, achieving single-sided coarse positioning. At the same time, the inner angle of the two L-shaped bases will also limit the two sides of the lower fixture, thus achieving coarse positioning on three sides in the horizontal direction.

[0032] Subsequently, the positioning module precisely positions the lower fixture in the horizontal direction. At the same time, it applies downward pressure to the lower fixture in the Z-axis direction, pressing the lower fixture onto the surface of the horizontal support plate, thereby achieving complete position fixation and ensuring that the lower fixture is located in the same Z-axis direction relative to the upper fixture.

[0033] After the lower fixture is positioned and fixed, two lateral assembly cylinders and one intermediate assembly cylinder move synchronously, moving the upper fixture downwards until the upper fixture aligns with the lower fixture. The lateral assembly cylinders and the intermediate assembly cylinder remain extended to prevent the upper and lower fixtures from separating. Meanwhile, the positioning module does not reset after completing its operation, maintaining the positioning and fixation of the lower fixture.

[0034] During the testing process, the screen glass panel moves upward under the lower fixture and eventually fits against the lower fixture for testing. Throughout the entire testing process, both the upper and lower fixtures are firmly fixed in position, and the lifting pressure of the screen glass panel will not cause displacement of the upper and lower fixtures, resulting in high alignment accuracy of automated testing.

[0035] The aforementioned limiting protrusion is a guide wheel. The side of the lower fixture corresponding to the guide wheel is provided with a limiting groove 12. The guide wheel can rotate. During the process of the lower fixture abutting against the limiting groove, the guide wheel provides rolling friction, which makes it easy to directly insert into place and has a good guiding effect. The groove of the limiting groove is provided with a guide surface.

[0036] For the lower fixture, its positioning accuracy is crucial. Poor positioning accuracy can lead to misalignment between the lower and upper fixtures, causing electrical connection failure at the joint. This is especially problematic after replacing the lower fixture, as it can easily result in poor contact and affect the testing progress. Therefore, a positioning module is designed, including a front positioning component 13 and an end positioning component 14. The front and end positioning components are used to limit and fix the corresponding corners of the lower fixture. Effective fixing of the four corners achieves overall fixation and also facilitates relatively convenient posture correction.

[0037] Specifically, the first-end positioning assembly includes a first Z-axis clamping cylinder 15 and a first X-axis clamping cylinder 16. The first Z-axis clamping cylinder has a flat clamping block 17, and the first X-axis clamping cylinder has an L-shaped horizontal clamping block 18. The first X-axis clamping cylinder is also connected to a first Y-axis clamping cylinder 19, which drives the first X-axis clamping cylinder to move along the Y-axis. The second-end positioning assembly includes a second Z-axis clamping cylinder 20 and a second Y-axis clamping cylinder 21. The second Z-axis clamping cylinder has an L-shaped vertical clamping block 22, and the second Y-axis clamping cylinder has a flat clamping block 23.

[0038] During the positioning and fixing process, the first-end positioning component and the second-end positioning component operate synchronously, that is, the first Z-axis clamping cylinder, the first X-axis clamping cylinder, the first Y-axis clamping cylinder, the second Z-axis clamping cylinder, and the second Y-axis clamping cylinder operate synchronously.

[0039] In the first-end positioning assembly, the first Z-axis clamping cylinder is connected to the flat clamping block, which is mainly used to clamp the first fixture onto the surface of the horizontal support plate in the Z-axis direction; the first X-axis clamping cylinder and the first Y-axis clamping cylinder work together to drive the L-shaped horizontal clamping block to move, one moving along the X-axis direction and the other moving along the Y-axis direction. When the two move simultaneously, they can move the L-shaped horizontal clamping block directly in the oblique direction. The L-shaped horizontal clamping block can apply pressure to the two sides of the corner of the lower fixture, forcing the lower fixture to move in the horizontal direction; the corresponding first-end positioning assembly on the other side has the same action mode as described above.

[0040] In the end-positioning assembly, due to the presence of a limiting protrusion, there is a small contact gap between the limiting protrusion and the corresponding limiting groove, so it does not require excessive adjustment. To address this, a second Z-axis clamping cylinder and a second Y-axis clamping cylinder were designed. The second Y-axis clamping cylinder drives the flat clamping block to push against the side of the lower fixture (achieved by the cooperation of two flat clamping blocks in the two end-positioning assemblies). The second Z-axis clamping cylinder drives the L-shaped vertical clamping block downward. The L-shaped vertical clamping block applies pressure to the surface of the lower fixture, pressing the lower fixture against the surface of the horizontal support plate. At the same time, the side of the L-shaped vertical clamping block limits the movement on one side of the limiting protrusion. That is, the vertical protrusion of the L-shaped vertical clamping block is provided with a guide slope. When moving vertically, the guide slope contacts the upper edge of the side of the lower fixture. When moving downward, a squeezing force is generated, forcing the lower fixture to move along the X-axis until it releases the contact with the guide slope, that is, the inner surface of the vertical protrusion contacts the surface of the side of the lower fixture.

[0041] After the aforementioned cylinders complete their actions, the two L-shaped horizontal pressure blocks correct and limit the posture of the two corners of the lower fixture on the side away from the limiting protrusion. At the same time, they push the lower fixture towards the vertical protrusions of the two L-shaped vertical pressure blocks. Since the applied force is at one corner of the lower fixture, in order to ensure the accuracy of posture adjustment, two planar pressure blocks are used to assist in positioning on the sides of the lower fixture on both sides of the L-shaped vertical pressure blocks. This confines the lower fixture within the frame space formed by the L-shaped vertical pressure blocks, the L-shaped horizontal pressure blocks, and the planar pressure blocks. With the cooperation of the planar pressure blocks and the horizontal surfaces on the L-shaped vertical pressure blocks, vertical fixation is achieved, and the lower fixture can be precisely fixed in position, thus allowing for accurate assembly with the upper fixture.

[0042] The positioning module also includes a third Z-axis clamping cylinder 24, which is equipped with a power supply connector 25. The lower fixture also requires power. To ensure safety, the power supply is designed independently. The power supply connector is inserted into the corresponding position of the lower fixture by the action of the third Z-axis clamping cylinder to provide power. When the lower fixture needs to be replaced, the third Z-axis clamping cylinder moves the power supply connector upward and pulls it out of the lower fixture. It is convenient and reliable.

[0043] For the movement of the upper jig, both the lateral assembly cylinder and the intermediate assembly cylinder are fixedly connected to the upper top plate via cantilever brackets 26, improving the overall hoisting stability. The lateral assembly cylinder is equipped with a lifting connecting plate 27, which is locked to the side frame of the upper jig, limiting the assembly position of the upper jig and facilitating disassembly and assembly. The modules are independent. A guide rail 28 is also provided between the lifting plate and the lateral mounting plate to ensure the stability of the lifting movement. The intermediate assembly cylinder is equipped with a gantry 29, which is fixedly connected to the two sides of the upper jig, ensuring even and reliable force distribution. Handles 30 are provided on the outer periphery of both the upper jig and the upper top plate for easy disassembly and assembly.

[0044] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
