Description

Technical Field

[0001] This utility model relates to the field of measurement equipment technology, and in particular to a detection device based on visual recognition technology. Background Technology

[0002] In the existing technology, the original inspection fixture structure is in a separate island area. Each individual part requires a fixed inspection fixture mechanism to measure its dimensions. The dimensions are manually recorded and then entered into the computer for storage. When switching projects, the fixed inspection fixture mechanism is moved as a whole and replaced with another fixed inspection fixture mechanism for inspection.

[0003] The existing technology application number is 2024200504214. The part measurement is done by the employee visually aligning the infrared light with the marked point. Visual alignment has an error of 0.2-0.3mm, which has a certain impact on the final measurement result. In addition, the overall area is 4 square meters, which is a large area. The full-size measurement takes about 45 seconds, which is inefficient.

[0004] Therefore, it is necessary to design a detection device based on visual recognition technology to solve the above problems. Utility Model Content

The detection module comprises a visual detection mounting bracket disposed on the side wall of the worktable, a lateral drive module disposed on the visual detection mounting bracket, several sets of visual mounting plates driven by the lateral drive module, and a visual sensor fixedly mounted on the visual mounting plates. The machine includes a vision camera positioned facing the quick-change module. The clamping and limiting module includes a product limiting block positioned below the detection module, an X-axis positioning block positioned at one end of the product limiting block, a flip clamping module positioned on both sides of the product limiting block, and a clamping assembly positioned below the product limiting block for clamping the product. The quick-change module includes a first column length detection block and a second column length detection block, both detachable and mounted on the machine's worktable. Several sets of limiting blocks are also provided on the first column length detection block and the second column length detection block.

[0008] Preferably, the detection module is also connected to a PLC data measurement and acquisition system for receiving and recording detection data. The vision camera is electrically connected to the PLC data measurement and acquisition system, and the PLC data measurement and acquisition system is also externally connected to a display.

[0009] Preferably, the drive end of the flip clamping module is further provided with an upper limit block for pressing the product surface, and the clamping assembly includes a clamping device and a clamping block provided at the drive end of the clamping device for supporting the bottom of the product.

[0010] The beneficial effects of this utility model are as follows: This technical solution designs a detachable, split quick-change module and a clamping and limiting module to be used for measuring different models of products. Only some modules need to be replaced to meet the measurement requirements of different parts.

[0015] Reference Figures 1 to 3 A detection device based on visual recognition technology includes a device workbench 1, a clamping and limiting module 4 disposed on the surface of the device workbench, a quick-change module 5 disposed at the bottom of the clamping and limiting module, and a detection module 3 disposed on the device workbench 1 and corresponding to the quick-change module 5.

[0016] The detection module 3 includes a vision detection mounting bracket set on the side wall of the equipment workbench 1, a lateral drive module set on the vision detection mounting bracket, several sets of vision mounting plates driven by the lateral drive module, and a vision camera 31 fixedly mounted on the vision mounting plate. The vision camera is set to face the quick-change module 5 and is used to detect the marking points of the product parts.

[0017] The detection module 3 is also connected to a PLC data measurement and acquisition system for receiving and recording detection data;

[0018] The vision camera is electrically connected to the PLC data measurement and acquisition system. The PLC data measurement and acquisition system is also externally connected to a display 32, which displays the measurement data and the calculated data through the display module. The display is also equipped with a receiving module for receiving data from the information communication module, and both the information communication module and the receiving module are electrically connected to the PLC data measurement and acquisition system.

[0019] The clamping and limiting module 4 includes a product limiting block 41 disposed below the detection module 3, an X-axis positioning block 42 disposed at one end of the product limiting block, a flip clamping module 43 disposed on both sides of the product limiting block, and a clamping component 44 disposed below the product limiting block for clamping the product.

[0020] The drive end of the flip clamping module 43 is also provided with an upper limit block for pressing the product surface.

[0021] The clamping assembly 44 includes a clamping device 441 and a clamping block 442 disposed at the driving end of the clamping device for supporting the bottom of the product.

[0022] The quick-change module 5 includes a first column length detection block 51 and a second column length detection block 52, which are detachable and mounted on the workbench 1 of the equipment. The first column length detection block 51 and the second column length detection block 52 are fixedly installed by bolts and can be quickly disassembled and installed. They can be replaced and matched for testing according to different product models. The tops of the first column length detection block 51 and the second column length detection block 52 are both set to abut against and fit the product limiting block 41.

[0023] To facilitate installation on the first column length detection block 51 and the second column length detection block 52, several sets of limiting blocks are also provided on the first column length detection block 51 and the second column length detection block 52.

[0024] In this implementation case, a fixture is selected according to the product model, and the product is installed on the workbench of the equipment and aligned with the detection module. The rubber strip to be tested is installed into the product limiting block 41, and both ends are fixed by the flip clamping module 43 and the clamping assembly 44. The ends are held by the X positioning block for positioning to ensure the accuracy of the detection module. Other parts are then installed into the first column length detection block 51 and the second column length detection block 52 and limited by the limiting blocks. The markings on the product are then detected by the vision camera 31, and the coordinate information is transmitted to the PLC data measurement and acquisition system. The program set inside the PLC data measurement and acquisition system calculates the size of the product and saves the record.

[0025] The advantages of this utility model are that the technical solution is designed with detachable, split quick-change modules and clamping and limiting modules to accommodate the measurement of different product models. Only some modules need to be replaced to meet the measurement requirements of different parts. At the same time, it is equipped with a PLC data measurement and acquisition system, which quickly extracts the marked point information through the vision inspection module and calculates the product size according to the set program to achieve rapid inspection.
