Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to a flatness testing device. Background Technology

[0002] In industrial manufacturing, many products have strict requirements for flatness. Whether the flatness meets the standards directly affects the subsequent assembly accuracy, performance, and even the overall quality of the product. For example, in the production of electronic components and precision mechanical parts, deviations in product flatness can lead to difficulties in component assembly, poor contact, and even equipment failure.

[0003] Currently, there are two main methods for flatness inspection commonly used in the industry: one is manual inspection using tools such as dial indicators and straightedges. This method not only requires inspectors to have high operational skills and experience, but also has extremely low inspection efficiency, making it difficult to meet the inspection needs of mass production. In addition, manual inspection is easily affected by subjective factors, making it difficult to guarantee the accuracy and consistency of the inspection results. The other method is to use some automated inspection equipment. However, most existing automated inspection equipment has a complex structure and a limited inspection range. It can usually only inspect a single product at a time, resulting in low inspection efficiency. Furthermore, the operation of positioning and fixing the product is cumbersome, making it difficult to quickly achieve stable fixing of the product, which further affects the inspection efficiency and accuracy.

[0004] Therefore, designing a flatness testing device that can simultaneously test multiple products, provide convenient and stable product positioning, and achieve high testing efficiency and accuracy has become an urgent technical problem to be solved. Utility Model Content

[0005] The main purpose of this utility model is to provide a flatness detection device, which overcomes the shortcomings of existing flatness detection devices such as low detection efficiency, cumbersome product positioning and fixing, and difficulty in guaranteeing detection accuracy.

[0006] To achieve the above objectives, this utility model provides a flatness detection device, comprising a first driving module (multiple), a placement module, a second driving module, and a detection module, wherein:

[0007] The drive module includes a first driver, a first slide rail assembly, a second slide rail assembly, and a first drive plate. The first slide rail assembly and the second slide rail assembly are respectively located on both sides of the first driver. The two ends of the first drive plate are respectively connected to the first slide rail assembly and the second slide rail assembly, and the middle part of the first drive plate is connected to the drive end of the first driver (driven by the first driver, so that the first drive plate moves on the first / second slide rail assembly for placement before product inspection and removal after inspection).

[0008] The placement module includes a mounting plate and several limiting units. The mounting plate is fixedly installed on the top of the first drive plate. The mounting plate has multiple placement areas, and limiting units are provided around the placement areas. Each limiting unit includes a fixed block, a movable block, a threaded cylinder, a first guide rod, and a second guide rod. The fixed block is fixed to the mounting plate, and the threaded cylinder is installed on the fixed block. The movable block is connected to the drive end of the threaded cylinder. The first guide rod and the second guide rod are located on both sides of the threaded cylinder and are used to guide the movable block when it moves relative to the fixed block. (After the product to be tested is placed in the placement area, it is limited and fixed by the limiting units. Specifically, the threaded cylinder drives the movable block to move towards the product side, thereby resisting the product and fixing it. The limiting units can be installed in the four directions of the placement area for all-round fixation.)

[0009] The second drive module includes a first bracket, a second bracket, a third slide rail assembly, a fourth slide rail assembly, and a second drive plate. The first drive module is located between the first bracket and the second bracket. The third slide rail assembly is mounted on the top of the first bracket, and the fourth slide rail assembly is mounted on the top of the second bracket. The second drive plate is mounted between the third slide rail assembly and the fourth slide rail assembly (the second drive plate can be moved between the third and fourth slide rail assemblies by a driver (not shown), thereby adjusting the distance between the laser line scanning unit and the product).

[0010] The detection module includes a fifth slide rail assembly, a sixth slide rail assembly, a third drive plate, a detection mounting frame, a first laser line scanning unit, and a second laser line scanning unit. The fifth and sixth slide rail assemblies are both fixed to the second drive plate. The third drive plate is installed between the fifth and sixth slide rail assemblies. The detection mounting frame is fixedly installed on the third drive plate, and the first and second laser line scanning units are fixedly installed on the detection mounting frame. The first and second laser line scanning units are used to detect the flatness of the product (the third drive plate can be moved between the fifth and sixth slide rail assemblies by a driver (not shown), thereby causing the laser line scanning units to move horizontally, thus enabling the detection of products in multiple placement areas and improving efficiency).

[0011] As a further preferred embodiment of the above technical solution, the mounting plate is fixedly mounted to the first drive plate by a mounting rod.

[0012] As a further preferred embodiment of the above technical solution, one end of the first guide rod and one end of the second guide rod are both fixedly installed on the movable block, and the other ends of the first guide rod and the second guide rod both penetrate the fixed block.

[0013] As a further preferred embodiment of the above technical solution, the number of placement areas for each mounting plate is 2.

[0014] As a further preferred embodiment of the above technical solution, the number of the first driving modules is 2.

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

[0016] 1. High detection efficiency: This utility model can place and fix multiple products at the same time by setting up multiple placement areas. With the horizontal movement of the laser line scanning unit in the detection module, it can quickly complete the flatness detection of multiple products.

[0017] 2. Stable and reliable product fixation: The limiting unit in the placement module uses a threaded cylinder to drive the moving block, and with the precise guidance of the first and second guide rods, it can stably fix the product from all sides, preventing the product from shifting during the testing process and ensuring testing accuracy; moreover, the operation of the limiting unit is highly automated, eliminating the need for manual fixing and reducing the difficulty of manual operation.

[0018] 3. High versatility and high detection accuracy: The second drive module can adjust the distance between the laser line scanning unit and the product, which can adapt to the detection needs of products with different thicknesses and specifications; the setting of dual laser line scanning units reduces the detection blind zone and can perform multi-angle and all-round detection of the product plane to ensure the accuracy of the detection data; at the same time, the setting of slide rail components in each drive module ensures the smoothness and accuracy of the movement of each moving part, further improving the detection accuracy of the device.

[0031] The detection module 4 includes a fifth slide rail assembly 41, a sixth slide rail assembly 42, a third drive plate 43, a detection mounting frame 44, a first laser line scanning unit 45, and a second laser line scanning unit 46.

[0034] Furthermore, the number of placement areas 23 for each mounting plate 21 is 2.

[0035] Furthermore, the number of the first driving modules 1 is 2.

[0036] Regarding this utility model:

[0037] Material loading stage: The operator controls the first driver 11 of one of the first drive modules 1 to start, driving the first drive plate 14 to move along the first slide rail assembly 12 and the second slide rail assembly 13 to the preset loading position; the two products to be tested are placed in the two placement areas 23 of the mounting plate 21 respectively; the operator controls the threaded cylinder 223 of each limit unit 22 to start, driving the moving block 222 to move along the first guide rod 224 and the second guide rod 225 toward the product, until the moving block 222 tightly abuts against the product, completing the product fixing.

[0038] Detection preparation stage: The first driver 11 is restarted, driving the first driver board 14 to move the placement module 2 and the fixed product to directly below the detection module 4; at the same time, the driver of the second driver module 3 is started, driving the second driver board 35 to move along the third slide rail assembly 33 and the fourth slide rail assembly 34, adjusting the distance between the detection module 4 and the product, so that the first laser line scanning unit 45 and the second laser line scanning unit 46 are at the optimal detection distance.

[0039] Detection phase: The driver of the control detection module 4 is started, driving the third drive board 43 to move along the fifth slide rail assembly 41 and the sixth slide rail assembly 42, which in turn drives the first laser line scanning unit 45 and the second laser line scanning unit 46 to move horizontally; during the movement, the first laser line scanning unit 45 and the second laser line scanning unit 46 perform flatness detection on the products in the two placement areas 23, and transmit the detection data to the control system (not shown) in real time for processing and analysis.

[0040] Material feeding and alternating operation phase: After inspection, the first driver 11 drives the first drive plate 14 to move the placement module 2 and the inspected product back to the loading position. The operator controls the threaded cylinder 223 to reset and remove the inspected product. While the first drive module 1 is driving the product for inspection, the operator can perform a loading operation on the placement module 2 corresponding to the other first drive module 1, realizing the synchronous operation of inspection and loading, and improving inspection efficiency.
