[0041] 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, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.
[0042] like Figures 1-13 The large-surface metal appearance inspection device shown includes a front large-surface inspection mechanism 1, a side inspection mechanism 2 and a back large-surface inspection mechanism 3; the front end of the front large-surface inspection mechanism 1 is a loading port 4, which is provided with an ion wind rod and a VUV component; the loading port 4 is added with an ion wind rod and a VUV component, and the product is cleaned before inspection to reduce dirt and burrs and reduce visual misjudgment; the end of the back large-surface inspection mechanism 3 is a unloading port 5.
[0043] like Figure 2-Figure 4 As shown, the front large-surface detection mechanism 1 includes an XYZR four-axis positioning drive device 11 and a front large-surface visual detection component 12.
[0044] The XYZR four-axis positioning drive device 11 is used to transport products to the visual inspection system for inspection; it includes an XYZR four-axis drive assembly 111 and a positioning fixture 112 mounted on the XYZR four-axis drive assembly. The XYZR four-axis drive assembly includes an X-axis linear module 113, which is equipped with a sliding connection plate 114, and a Y-axis linear module 115 mounted on the sliding connection plate; the Y-axis linear module is connected to a Z-axis lifting module 116; the Z-axis lifting module is connected to an R-axis motor rotation module 117; the positioning fixture is mounted on the R-axis motor rotation module.
[0045] In order to reduce the equipment space and size while ensuring the accuracy of synchronization, two sets of Y-axis linear modules, Z-axis lifting modules, R-axis motor rotation modules and positioning fixtures are symmetrically arranged on the sliding connecting plate; the two sets of Y-axis linear modules, Z-axis lifting modules, R-axis motor rotation modules and positioning fixtures share one X-axis linear module.
[0046] At the same time, in order to ensure stability during movement, auxiliary slide rails 118 are provided on both sides of the X-axis linear module, and both ends of the sliding connecting plate slide on the auxiliary slide rails through auxiliary sliders.
[0047] The positioning fixture 112 includes a bottom connecting plate 119, which is connected to a top connecting plate 1111 via connecting posts 1110.

The long-side positioning assembly includes a long-side positioning cylinder and a long-side positioning post mounted on the long-side positioning cylinder; the short-side positioning assembly includes a short-side positioning cylinder and a short-side positioning post mounted on the short-side positioning cylinder. The long-side positioning assembly in this embodiment corresponds to the long side of the product, that is, it positions the product in the long direction.
[0048] The top connecting plate is provided with a vacuum suction cup assembly 1114 and a positioning retaining edge 1115. The vacuum suction cup assembly is used to fix the product, greatly reducing the risk of material falling.
[0049] The positioning ribs are respectively arranged on the long side and the short side of the top connecting plate. The positioning ribs include an inner positioning rib and an outer positioning rib, which can adapt to products of different sizes.
[0050] This device integrates the XYZR four axes, and shares one X-axis when dual-channel drive is used. At the same time, a positioning fixture is set on the R-axis. The four-axis motion and positioning components move independently and can move simultaneously. While ensuring the repeatability of the product, multi-dimensional movements of the product can be performed simultaneously, thereby ensuring that the product can complete relatively complex movements to meet the detection requirements. At the same time, some handling components can be reduced, reducing equipment space and reducing equipment size.
[0051] The action process is as follows: ① Place the product in the positioning fixture and start the equipment; ② The positioning cylinder moves to precisely position the product, vacuum adsorbs the product, and releases the positioning cylinder; ③ The XYZR axes complete different actions according to the visual inspection requirements, and after visual inspection, wait for unloading.
[0052] The front large-surface visual inspection component 12 includes a 16K camera station 121 , an internal stress detection station 122 and a 16K time-sharing station 123 .
[0053] like Figure 5-Figure 9 As shown, the side detection mechanism 2 includes a first transport component 21 , a side detection fixture component 22 and a side visual detection component 23 .

The secondary positioning module includes a secondary positioning support plate 214, which is connected to the flip cantilever 213. The secondary positioning support plate is provided with a positioning assembly, a positioning rib 5, and a vacuum suction cup assembly 216. A photoelectric sensing assembly 2113 is also provided on the surface of the secondary positioning support plate 214.
[0055] The flip cantilever 213 is connected to the bottom surface of the secondary positioning support plate 214; the positioning assembly is arranged on the bottom surface of the secondary positioning support plate; the vacuum suction cup assembly 216 is arranged to pass through the surface of the secondary positioning support plate; the positioning ribs 215 are respectively arranged on the long side and short side of the secondary positioning support plate.
[0056] The positioning assembly includes a long side positioning assembly and a short side positioning assembly; the edges of the secondary positioning support plate are respectively provided with positioning assembly moving grooves 2111 at positions corresponding to the long side positioning assembly and the short side positioning assembly.
[0057] The long-side positioning assembly includes a long-side positioning cylinder 217 and a long-side positioning post 219 mounted on the long-side positioning cylinder. The short-side positioning assembly includes a short-side positioning cylinder 218 and a short-side positioning post 2110 mounted on the short-side positioning cylinder. The long-side positioning cylinder and the short-side positioning cylinder are mounted on the bottom surface of the secondary positioning support plate. The long-side positioning post and the short-side positioning post each move within the corresponding positioning assembly moving groove. The long-side positioning assembly in this embodiment corresponds to the long side of the product, that is, it positions the product along its long side.
[0058] This device combines the secondary positioning module and the flip lifting module into an integral mechanism through a connecting plate and a flip cantilever, so that the product is precisely positioned by the secondary positioning module before flipping, and the product is fixed by the positioning cylinder and vacuum suction cup, which greatly reduces the risk of material falling; and the flip part adopts a rotating motor to ensure flipping stability and flipping accuracy; while reducing some handling components, reducing equipment space, and reducing equipment size, it also reduces equipment costs.
[0059] The action process is as follows: ① The lifting component reaches the material picking position; ② After the photoelectric sensing component is triggered to sense the product, the long and short side positioning cylinders are activated to complete the product positioning; ③ The vacuum suction cup component works to absorb the product to prevent material from falling; ④ The lifting component moves to the rotation position, the flip motor works, driving the flip cantilever to rotate and flip the product; ⑤ The flipped product is placed in the inspection fixture; ⑥ The product flip positioning is completed.
[0060] The side detection fixture assembly 22 includes an XYRU four-axis drive assembly 221 and a carrier assembly 222 disposed on the XYRU four-axis drive assembly; the carrier assembly is provided with a vacuum suction cup assembly.
[0061] The side vision detection component 23 includes a 4K camera station 231 and an area array camera station 232 .
[0062] like Figure 10-13 As shown, the back large surface detection mechanism includes a second transport component 31 , a back surface detection fixture component 32 and a back surface visual detection component 33 .
[0063] The back detection fixture assembly 32 includes an XYZR four-axis drive assembly and a carrier assembly arranged on the XYZR four-axis drive assembly; the back visual inspection assembly 33 includes a shaft tip angle detection station 331, a thumb groove detection station 332, an inner wall detection station 333, a back time-sharing station 334 and an R angle detection station 335.
[0064] This device sequentially inspects the front, side, back, and rounded corners of multiple products. Using a dual-channel drive mechanism and a transport mechanism, it handles product transport, flipping, and positioning. Each mechanism operates independently and collaboratively to complete multi-faceted inspection of each product, meeting customer needs.
[0065] The overall working process of the machine is as follows: ① Manually complete product loading from the loading port; ② The dual-channel four-axis positioning drive grabs the product and completes ion wind bar / VUV dust removal and front inspection in sequence; ③ The first handling component transports the product to the flip positioning component to flip the product and hand it over to the side inspection fixture; ④ The dual-channel transfer fixture is used to inspect the side of the product; ⑤ The second handling component transports the product to the back inspection fixture for product back inspection and R angle inspection; ⑥ Manual unloading of the product at the unloading port.
[0066] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can make modifications or deformations to the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
