Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology equipment, and in particular to a dual-station five-axis inspection device. Background Technology

[0002] During the production and processing of products such as mobile phone back covers, damage and defects are easily caused by environmental factors (such as dust and humidity) and process factors (such as deviations in processing precision). To reduce resource waste, product defects need to be detected before entering subsequent processing stages. This is usually accomplished by using a vision component consisting of a camera, lens, and light source in conjunction with a mechanical structure.

[0003] In existing inspection equipment, vision components are mostly fixedly installed, and the product carrier only has a single direction of movement. When the product to be inspected has multiple inspection surfaces, or when there are multiple inspection requirements for the same inspection surface, traditional equipment needs to deploy multiple sets of vision components. Moreover, the camera angles, installation methods, and camera light source combinations of each set of components are different. This not only leads to high equipment costs and large machine size, but also makes it impossible to achieve modularization of the mechanism, resulting in poor compatibility and difficulty in adapting to the docking requirements of different upstream and downstream processing equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dual-station five-axis inspection device, which solves the defects of existing inspection equipment such as a large number of vision components, high cost, large machine size and inability to be modularized.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-station five-axis detection device, including a feeding and conveying module, which is connected to a feeding and positioning module, and the feeding and conveying module transports the product to the feeding and positioning module; the output end of the feeding and positioning module is connected to a five-axis detection module one, which absorbs the product in the feeding and positioning module and transfers it to a five-axis detection module two; the five-axis detection module one and the five-axis detection module two have the same structure and are arranged opposite to each other; the output end of the five-axis detection module two is connected to an unloading transfer module, and an unloading and conveying module is arranged behind the unloading transfer module.

[0006] Furthermore, the material handling module of this utility model includes a handling lifting mechanism, a product rotating mechanism, and a product pitch-changing cylinder; the product pitch-changing cylinder is disposed at the rotating end of the product rotating mechanism; the fixed end of the product rotating mechanism is connected to the handling lifting mechanism; and the movable end of the product pitch-changing cylinder is provided with a vacuum suction cup.

[0007] Furthermore, the feeding and positioning module of this utility model includes a positioning mechanism carrier, a positioning mechanism side, and a flipping power unit; the positioning mechanism carrier adsorbs the product, and both the positioning mechanism carrier and the positioning mechanism side are mounted on a rotating bracket; the output end of the flipping power unit is connected to the rotating bracket to drive the rotating bracket to flip.

[0008] Furthermore, the five-axis detection module one / five-axis detection module two of this utility model includes a vision carrier, an X-axis translation, a Y-axis translation, a Z-axis lifting, an A-axis flipping power unit, a C-axis rotation power unit, and a vision component. The vision carrier is mounted on a rotating arm, and the A-axis flipping power unit is connected to the rotating arm to drive the rotating arm to flip. The C-axis rotation power unit is connected to the vision carrier to drive the product on the vision carrier to rotate. A vacuum suction cup is provided on the vision carrier. The vision component is mounted on the Z-axis lifting mechanism.

[0009] Furthermore, both the unloading transfer module and the unloading transport module described in this utility model have vacuum suction cups.

[0010] The beneficial effect of this utility model is that it solves the defects existing in the background technology. 1. The vision components are standardized into a single camera and light source combination. The product position and angle are adjusted by driving the X, Y, A, and C axes, and the detection distance of the vision components is adjusted by the Z axis. This eliminates the need to deploy multiple vision components, reduces the number of cameras and lenses used, and significantly reduces the cost of vision components. At the same time, the machine layout is optimized, the machine size is reduced, and the overall manufacturing cost of the equipment is reduced. 2. With independent functions and unified interfaces for loading, positioning, detection and unloading modules, it can be matched with a variety of different front and rear equipment, with high compatibility; the back-to-back dual five-axis detection modules make the machine structure more regular, which is conducive to standardized production and later maintenance. 3. The combination of the A-axis (90°~270° rotation) and the C-axis (0°~360° rotation) allows for flexible adjustment of the angle of irregularly shaped products, ensuring that different inspection surfaces and features of the product are at the optimal inspection angle; the X and Y axes precisely drive the product to move directly below the camera, and the Z-axis precisely adjusts the inspection distance to ensure inspection accuracy, making it suitable for the inspection needs of irregularly shaped products with multiple features and angles.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0013] like Figures 1-6 The device shown is a dual-station five-axis inspection unit, which inspects the rear camera area of ​​a mobile phone. It includes a loading and transport module 31, which connects to a loading and positioning module 32. The loading and transport module 31 transports the product to the loading and positioning module 32. The output end of the loading and positioning module 32 connects to a first five-axis inspection module 33, which picks up the product from the loading and positioning module and transfers it to a second five-axis inspection module 34. The first and second five-axis inspection modules have identical structures and are positioned back-to-back. This back-to-back dual five-axis design allows for direct material transfer between the carriers, enabling product carrier switching while simultaneously flipping the product, allowing the machine to complete comprehensive product inspection.

[0014] The output end of the five-axis detection module 2 is connected to the unloading transfer module 35, and the unloading transfer module is provided with an unloading and handling module 36 behind it.

[0015] like Figure 2 As shown, the material handling module includes a handling lifting mechanism 39, a product rotation mechanism 38, and a product pitch-changing cylinder 37; the product pitch-changing cylinder is located at the rotating end of the product rotation mechanism; the fixed end of the product rotation mechanism is connected to the handling lifting mechanism; and the movable end of the product pitch-changing cylinder is equipped with a vacuum suction cup.

[0016] like Figure 3 As shown, the loading and positioning module includes a positioning mechanism carrier 310, a positioning mechanism side 311, and a flipping power unit 312; the positioning mechanism carrier adsorbs the product, and both the positioning mechanism carrier and the positioning mechanism side are mounted on a rotating bracket 320; the output end of the flipping power unit is connected to the rotating bracket to drive the rotating bracket to flip.

[0017] like Figure 4 As shown, the five-axis detection module one and the five-axis detection module two have the same structure and are arranged back to back, including a vision vehicle 316, an X-axis translation 315, and a Y-axis translation (317 adopts a dual-motion sub-module, such as...). Figure 5 As shown), the system includes a Z-axis lifting mechanism 318, an A-axis tilting power unit 313, a C-axis rotation power unit 314, and a vision assembly 319. The vision carrier is mounted on a rotating arm 321. The A-axis tilting power unit is connected to the rotating arm to drive the rotating arm to tilt. The C-axis rotation power unit is connected to the vision carrier to drive the product on the vision carrier to rotate. The vision carrier is equipped with a vacuum suction cup. The vision assembly is mounted on the Z-axis lifting mechanism, as shown below. Figure 6 As shown.

[0018] The two back-to-back five-axis inspection modules can directly achieve simultaneous carrier docking and product flipping. After the first five-axis inspection module completes the inspection of the product system surface, its vision carrier can directly dock with the vision carrier of the adjacent second five-axis inspection module. While switching carriers, the product flipping is naturally achieved by taking advantage of the back-to-back layout of the two modules (without the need for an additional flipping mechanism). The second five-axis inspection module then inspects the user surface of the flipped product. The entire process does not require secondary loading or intermediate transfer waiting, realizing continuous inspection at dual workstations, significantly shortening the total inspection cycle of a single product, and is especially suitable for the high-efficiency inspection needs in mass production scenarios.

[0019] Moreover, the two five-axis detection modules share some auxiliary structures (such as some transmission components and wiring space) and are distributed in opposite directions along the same axis, which avoids the space waste of traditional parallel or distributed layouts, further compresses the horizontal / horizontal space occupied by the equipment, makes the machine structure more compact, and can be flexibly embedded into production lines of different lengths and widths, improving the adaptability of the equipment to the production line space.

[0020] Both the unloading transfer module and the unloading handling module are equipped with vacuum suction cups. In this embodiment, the docking is also achieved by using vacuum suction cups to adhere to the product surface (front / back).

[0021] The action process is as follows: In the feeding module, the feeding and handling module 31 adjusts its height under the drive of the handling and lifting mechanism 39, picks up the product from the previous inspection machine through a vacuum suction cup, adjusts the product angle through the product rotation mechanism 38 and adjusts the product spacing through the product pitch cylinder 37, and then transports the product to the feeding and positioning module 32. The positioning mechanism 311 of the feeding and positioning module 32 shrinks and straightens the product under the action of the cylinder (the driving cylinder of the positioning mechanism is not described in detail in this embodiment). The positioning mechanism carrier 310 adsorbs the product, and the secondary positioning mechanism further ensures that the product is centered. Then, the flipping power unit 312 drives the feeding and positioning module 32 to rotate 90° and dock with the vision carrier 316 of the five-axis inspection module 33. The vacuum suction cup set on the vision carrier 316 adsorbs the product and completes the product transfer.

[0022] When the dual five-axis inspection modules are working, the A-axis flipping power unit 313 of the five-axis inspection module 1 (inspecting the system surface of the product) drives the inspection module to flip to the appropriate angle, and the C-axis rotation power unit 314 drives the product on the vision carrier 316 to rotate. With the X-axis translation 315 and Y-axis translation 317, the center of the product inspection area is aligned with the center of the vision component 319. The Z-axis lifting 318 drives the vision component 319 to move up and down to the optimal inspection distance to complete the system surface inspection. After the inspection is completed, the vision carrier 316 of the five-axis inspection module 1 directly docks with the vision carrier of the five-axis inspection module 2 34. The product is flipped while switching carriers by vacuum adsorption. The five-axis inspection module 2 34 adopts the same axis motion adjustment method as the five-axis inspection module 1 33 to complete the inspection of the user surface of the product.

[0023] In the unloading module, the unloading and handling module 36 picks up the product from the vision carrier 316 of the five-axis inspection module 2 34 and moves the product to the unloading transfer module 35 for buffering. When the subsequent process requires it, the unloading and handling module 36 moves the product to the downstream inspection machine to complete the entire inspection process.

[0024] The above description is only a specific embodiment of the present utility model. Various examples and illustrations do not constitute a limitation on the substantive content of the present utility model. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the description without departing from the essence and scope of the utility model.
