[0015] Now the utility model is further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0016] like Figure 1-Figure 3The XYZR four-axis positioning drive device shown is used to transport products to a visual inspection system for inspection; it includes an XYZR four-axis drive assembly 1 and a positioning fixture 2 arranged on the XYZR four-axis drive assembly. The XYZR four-axis drive assembly includes an X-axis linear module 3, on which a sliding connection plate 4 is arranged, and on which a Y-axis linear module 5 is arranged; the Y-axis linear module is connected to a Z-axis lifting module 6; the Z-axis lifting module is connected to an R-axis motor rotating module 7; and the positioning fixture is arranged on the R-axis motor rotating module.

[0017] In order to reduce the equipment space and size while ensuring the accuracy of synchronization, two groups 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 groups of Y-axis linear modules, Z-axis lifting modules, R-axis motor rotation modules and positioning fixtures share one X-axis linear module.

[0018] At the same time, in order to ensure the stability during movement, auxiliary slide rails 8 are arranged on both sides of the X-axis linear module, and the two ends of the sliding connecting plate slide on the auxiliary slide rails through auxiliary sliders.

[0019] The positioning fixture 2 includes a bottom connection plate 9, which is connected to a top connection plate 11 via a connection column 10; a long side positioning component 12 and a short side positioning component 13 are arranged on the bottom connection plate; the long side positioning component includes a long side positioning cylinder and a long side positioning column arranged on the long side positioning cylinder; the short side component includes a short side positioning cylinder and a short side positioning column arranged on the short side positioning cylinder. The long side positioning component in this embodiment corresponds to the long side of the product, that is, the long side direction of the product is positioned.

[0020] The top connecting plate is provided with a vacuum suction cup assembly 14 and a positioning retaining edge 15. The vacuum suction cup assembly is used to fix the product, greatly reducing the risk of material falling.

[0021] 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.

[0022] This device integrates the XYZR four axes, and shares one X axis when dual-channel driving. At the same time, a positioning fixture is set on the R axis. The four-axis motion and positioning components are independent of each other and can act simultaneously. While ensuring the product's repetitive accuracy, multi-dimensional product movements can be performed simultaneously, thereby ensuring that the product can complete relatively complex movements to meet detection requirements; at the same time, some handling components can be reduced, reducing equipment space and reducing equipment size.

[0023] The action process is as follows: ① Place the product into the positioning fixture and start the equipment; ② The positioning cylinder moves, and after precise positioning of the product, the product is vacuum-adsorbed and the positioning cylinder is released; ③ The XYZR axis completes different actions according to the visual inspection requirements, and after visual inspection, waits for unloading.

[0024] 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 modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
