Description

Technical Field

[0001] This utility model relates to the field of glass panel inspection technology, and specifically to a glass loading and unloading device for glass panel inspection. Background Technology

[0002] Screen glass is a core material for electronic display devices, possessing characteristics such as high light transmittance, scratch resistance, and impact resistance. It is an indispensable component in current display terminals. After production, effective testing is required. Some products with touch functionality also require electrical testing to ensure they meet the standards for shipment.

[0003] Because of the sheet-like structure of the products, they are all stacked. When inspection is required, a robotic arm is needed to move the products. The robotic arm has a range of motion. The wider the range, the larger the robotic arm is, and the higher the purchase cost. In addition, the integration effect within the limited space of the inspection equipment is not good.

[0004] Furthermore, when using robotic arms, products require multiple corresponding hoppers, including loading hoppers, unloading hoppers, and non-product (NG) hoppers, to facilitate product differentiation. Therefore, the hoppers need to be located around the robotic arm. When there are many hoppers, the layout design of the hoppers places high demands. During the design process, the loading and unloading positions of each hopper must be considered. This results in problems such as high equipment manufacturing costs, difficult maintenance, and unreasonable operational layout. Moreover, the scattered and disorganized layout occupies space and is aesthetically unappealing. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a glass loading and unloading device that is compatible with glass panel inspection, which effectively controls the manufacturing cost, is convenient to maintain and repair, and is also convenient for loading and unloading.

[0006] To solve the above-mentioned technical problems, this utility model provides a glass loading and unloading device for glass panel detection, including two gantry frames. Three-axis moving components are installed on the two gantry frames. The three-axis moving components are connected to a crossbeam through a mounting frame. Suction cup components are installed at the bottom of both ends of the crossbeam. A first rotary motor is installed on the mounting frame and the crossbeam. A second rotary motor is installed between the suction cup components and the crossbeam. Multiple material bins are also installed between the two gantry frames. Each material bin includes a Z-axis lifting platform for stacking materials.

[0007] Furthermore, the three-axis movement assembly includes an X-axis lead screw module, a Y-axis lead screw module, and a Z-axis lead screw module that are connected in a mating manner.

[0008] Furthermore, a Z-axis lifting cylinder is provided between the second rotary motor and the suction cup assembly.

[0009] Furthermore, the suction cup assembly includes a mounting plate with multiple elongated holes, in which suction cups are disposed and secured with nuts.

[0010] Furthermore, the Z-axis lifting platform is mounted on a vertical support, and a U-shaped positioning plate is mounted on the top of the vertical support. Positioning cylinders are mounted on opposite sides of the U-shaped positioning plate, and positioning push blocks are mounted on the positioning cylinders.

[0011] Furthermore, a proximity sensor is also provided on the zigzag positioning plate.

[0012] Furthermore, a sliding plate is provided on the Z-axis lifting platform, and three slide rails are arranged parallel to the sliding plate and the Z-axis lifting platform. The slide rails on both sides are fixedly connected to the Z-axis lifting platform, and the slide rail in the middle is fixedly connected to the sliding plate.

[0013] Furthermore, a single-sided positioning block is provided on the sliding plate.

[0014] Furthermore, a reinforcing plate is provided on the crossbeam.

[0015] The beneficial effects of this utility model are:

[0016] 1. The three-axis moving components are supported and fixed above multiple hoppers using two gantry structures, which has the advantage of occupying less space on the equipment platform surface. In addition, the multiple hoppers are arranged compactly, which greatly reduces the size of the equipment.

[0017] 2. The three-axis moving assembly, together with the first and second rotary motors, can achieve movement and angle adjustment in the horizontal plane, fully covering the actual use requirements, replacing expensive robotic arms and greatly reducing manufacturing costs.

[0024] 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.

[0025] Reference Figures 1 to 4 As shown, one embodiment of the glass loading and unloading device for glass panel detection according to this utility model includes two gantry frames 1, and three-axis moving components 2 are provided on the two gantry frames. The three-axis moving components are connected to the crossbeam 4 through the mounting frame 3. The crossbeam is provided with a reinforcing plate 27 to improve strength. Suction cup components 5 are provided at the bottom of both ends of the crossbeam. A first rotary motor 6 is provided between the mounting frame and the crossbeam. A second rotary motor 7 is provided between the suction cup components and the crossbeam. Multiple material bins 8 are also provided between the two gantry frames. The material bins include a Z-axis lifting platform 9, on which materials 10 are stacked.

[0026] The aforementioned material silos should consist of at least three: a silo for the product to be tested, a silo for NG (no good) products, and a silo for BE (good) products. More silos can be added depending on the specific needs. The silos can be arranged in an array, for example... Figure 1 As shown, six hoppers are set up, three in a group, forming two groups arranged side by side. The openings of each hopper face the same side, making it easy for people to take the products away or place them in the hoppers.

[0027] The three-axis moving assembly is located above the array of hoppers and is secured by two gantry frames. This ensures stable installation and minimizes the use of internal platform space, occupying only the upper space above the hoppers, thus improving space utilization and allowing for ample placement space. The movement of the three-axis moving assembly drives the suction cup assembly, which, through coordinated X and Y axis movement, moves to the top of each hopper, providing a wider operating range compared to a robotic arm.

[0028] The suction cup assembly is used to pick up or place products. Through the first and second rotary motors, different postures can be adjusted on the horizontal plane. For example, if the position of the hopper and the placement position of the detection end are inconsistent, the second rotary motor can be used to rotate the picked-up product before it is placed.

[0029] Specifically, during use, the operator places the product to be tested into the corresponding hopper. The hopper is then lifted by a Z-axis lifting platform. Subsequently, a three-axis moving component moves horizontally, causing the suction cup component to move above the product. Then, the three-axis moving component moves vertically, causing the suction cup component to descend. The suction cup component then picks up the product. After picking up the product, the three-axis moving component moves the suction cup component upward and horizontally to the unloading point of the testing position. Through the movement of the three-axis moving component, the product is placed on the loading platform of the testing position.

[0030] Since this application has two suction cup components mounted on a single beam, the rotation of the first rotary motor allows both suction cup components to be positioned above the hopper for gripping or placing products, thus improving operational efficiency. For example, during the testing process, one suction cup component can grip a product to be tested. After testing, the tested product moves to the loading position, where the other suction cup component grips it. The first rotary motor then moves the suction cup component holding the product to be tested above the loading position, simultaneously rotating the tested product to the other side. This achieves continuous loading and unloading, eliminating the need to first place the tested product in the hopper before gripping and placing the product to be tested. This significantly reduces time and improves efficiency.

[0031] Furthermore, the crossbeam provides the possibility of outward extension. When the three-axis mechanism drives the crossbeam to be close to one of the gantry frames, the crossbeam can pass under the gantry frame from under the hopper and move to the outside, thus enabling loading and unloading without setting up clearance space.

[0032] Meanwhile, based on the different detection and feeding positions, the first rotary motor drives the crossbeam to rotate, enabling the suction cup assembly to move the product to the outer side in four directions, thereby greatly reducing design requirements and making it widely applicable.

[0033] Specifically, the three-axis movement assembly includes a mating X-axis lead screw module 11, a Y-axis lead screw module 12, and a Z-axis lead screw module 13. They cooperate to complete the three-axis movement, which is existing technology and will not be described in detail.

[0034] Since the two suction cup assemblies are assembled at the same height, when they move downwards to grasp materials, one suction cup assembly may come into contact with other products that do not need to be grasped. This could cause the products that do not need to be grasped to be squeezed. Therefore, a Z-axis lifting cylinder 14 is installed between the second rotary motor and the suction cup assembly. The three-axis moving assembly drives the suction cup assembly to lift the product above it. The suction cup assembly that needs to grasp the product continues to move downwards through the action of the Z-axis lifting cylinder, thereby grasping the product. The Z-axis lifting cylinder on the suction cup assembly that does not need to grasp the product does not move and will not come into contact with the product, thus effectively preventing the aforementioned unnecessary contact problem.

[0035] The suction cup assembly needs to be compatible with products of different sizes. Therefore, the suction cup assembly is designed to include a mounting plate 15 with multiple elongated holes 16. Suction cups 17 are placed inside the elongated holes and secured with nuts 18. The multiple elongated holes are on the same circumference, and their length direction is located in the corresponding diameter direction of the circumference. During adjustment, by locking at different positions within the elongated holes, the multiple suction cups can be moved closer or further apart, thus making it suitable for products of different sizes.

[0036] Reference Figures 4 to 6 As shown, the Z-axis lifting platform is mounted on the vertical support 19. A U-shaped positioning plate 20 is mounted on the top of the vertical support. Positioning cylinders 21 are mounted on the opposite sides of the U-shaped positioning plate, and positioning push blocks 22 are mounted on the positioning cylinders.

[0037] The U-shaped positioning frame can position the product in the inner frame, making it easy for the suction cup assembly to accurately grasp it. Specifically, the Z-axis lifting platform moves the product to the inner frame, and then two positioning cylinders extend, causing the positioning push blocks to move closer, so that the tray carrying the product is pushed to the middle position of the two positioning push blocks, achieving the purpose of adjusting the position. The action signals of the two positioning cylinders do not require manual operation. Instead, a proximity sensor 23 is set on the U-shaped positioning plate. When the Z-axis lifting platform moves the product up and is detected by the proximity sensor, the Z-axis lifting platform stops moving, and then the two positioning cylinders extend and reset after extending to their positions.

[0038] When operators place or retrieve products, the U-shaped positioning plate presents an inconvenience. Therefore, a sliding plate 24 is installed on the Z-axis lifting platform. The sliding plate can be pulled out or pushed back, making product placement and retrieval more convenient. Specifically, three slide rails 25 are arranged parallel to each other between the sliding plate and the Z-axis lifting platform. The slide rails on both sides are fixedly connected to the Z-axis lifting platform, and the slide rail in the middle is fixedly connected to the sliding plate. This method greatly improves the connection strength between the sliding plate and the surface of the Z-axis lifting platform, and the middle rail also enhances the strength of the sliding plate.

[0039] Since the two positioning cylinders mentioned above can only position the product in one direction, in order to improve the positioning accuracy, a single-sided positioning block 26 is set on the sliding plate. When placing the product, it is necessary to ensure that the side of the tray carrying the product abuts against the single-sided positioning block. After abutting, it can cooperate with the two positioning cylinders to form a three-sided positioning effect, which can accurately position the product and improve the gripping accuracy.

[0040] The placement of the aforementioned products is done manually, and the sliding plate only has a single-sided positioning block. Therefore, the products are not well positioned in the left and right directions, which can easily cause excessive misalignment during placement, preventing the products from passing through the inner frame of the U-shaped positioning plate and causing interference and collision problems. Therefore, two passive positioning blocks 28 are respectively set at the two corners of the U-shaped positioning plate near the single-sided positioning block. During the product's ascent, if the product's extraction plate is misaligned, it will contact the inclined surface of the corresponding passive positioning block and be squeezed and displaced during the continued process, thereby achieving the initial positioning effect. Then, a positioning cylinder is used for center positioning, effectively avoiding the problem of the extraction plate contacting the bottom surface of the U-shaped positioning plate.

[0041] During the aforementioned transfer process, the extraction trays also need to be moved, which is achieved through a suction cup assembly. Furthermore, during the transfer of the extraction trays, the extension of the positioning push block ensures that only one extraction tray is grasped at a time, minimizing impact on the extraction trays below.

[0042] 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.
