Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of SMT surface mount production lines, specifically a device for detecting the flatness of scraper blades. Background Technology
[0002] Over time, the blade of a solder paste squeegee used on circuit boards can become uneven due to compression and friction. Since circuit boards have very strict requirements for the flatness of solder paste, poor solder paste printing results are common in production. Operators cannot directly determine whether the poor printing is caused by the squeegee blade, so it is necessary to regularly check the flatness of the solder paste printing squeegee. To improve the efficiency of the inspection, it is necessary to use solder paste printing squeegee flatness inspection equipment for auxiliary inspection. Utility Model Content
[0003] The purpose of this invention is to provide a device for detecting the flatness of scraper blades, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for detecting the flatness of a scraper blade, comprising: a mounting base, a positioning groove provided on the mounting base, a pushing mechanism located behind the positioning groove, and a detection platform located in front of the positioning groove. The pushing mechanism includes a fixed plate, a limiting rod extending through the other side of one side of the fixed plate, a moving block slidably connected to the outer side of the limiting rod, limiting posts provided on both sides of the positioning groove on the mounting base, a spring cooperating with the outer side of the limiting rod, a fixed block connected to the top of the moving block, and a pushing block connected to the bottom of the fixed block.
[0005] As a further embodiment of this utility model, a mounting pad is provided on the top of the fixing block, and a handle is provided on the top of the mounting pad.
[0006] As a further embodiment of this invention, the mounting pad and the fixing block are fixed together by bolts.
[0007] As a further improvement of this invention, the pusher is made of rubber or silicone.
[0008] As a further embodiment of this utility model, the front end of the spring is connected and fixed to the moving block, and the rear end of the spring is connected and fixed to the fixed plate.
[0009] As a further embodiment of this invention, one end of the limiting rod is fixedly connected to the limiting post.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the scraper to be tested is placed above the positioning groove with the back of the blade in contact with the push block. The pushing mechanism presses one side of the blade edge against the side of the testing platform, simulating the force on the scraper when it is installed on the working equipment. This allows the scraper to be in the working installation state during testing, and the deformation of the scraper blade can be quickly checked by the contact state between the two. This improves the flatness detection accuracy of the scraper flatness, prevents false detection, and enhances the safety and reliability of the testing. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of a device for detecting the flatness of scraper blades;
[0012] Figure 2 This is an enlarged schematic diagram of the pushing mechanism. Detailed Implementation
[0013] Please see Figure 1-2 In this embodiment of the utility model, a device for detecting the flatness of a scraper blade includes a mounting base 1, a positioning groove 2 provided on the mounting base, a pushing mechanism 3 located behind the positioning groove, and a detection platform 4 located in front of the positioning groove.
[0014] The pushing mechanism 3 includes a fixed plate 31. A limiting rod 32 extending through the other side is provided on one side of the fixed plate 31. A moving block 33 is slidably connected to the outer side of the limiting rod. A limiting post 34 is fixed to the top of the mounting base 1. One end of the limiting rod is fixedly connected to the limiting post. A spring 35 is provided on the outer side of the limiting rod. One end of the spring 35 is fixed to the spring, and the other end of the spring is fixed to the fixed plate. A fixed block 36 is connected to the top of the moving block. A mounting pad 37 is provided on the top of the fixed block. A handle 38 is provided on the top of the mounting pad 37. A push block 39 is connected to the bottom of the fixed block 36. The scraper to be tested can be placed above the positioning groove with the back of the scraper in contact with the push block. At this time, the spring... 35 provides elasticity and pushes the moving block 33 to move. At this time, the moving block 33 can drive the fixed block 36 and the push block 39 fixedly connected to it to move together. At this time, one side of the push block 39 can fit against the back of the scraper to be tested. The scraper to be tested can be pushed by the push block 39 to clamp and fit against the testing platform. By observing the fit between the blade and the testing platform, it can be checked whether the scraper blade is deformed, thereby detecting the flatness of the scraper in operation. This utility model can be used with scrapers of different sizes for push-press testing, achieving the purpose of easily adapting to the testing of scrapers of various sizes, avoiding the use of multiple tooling fixtures and multiple non-standard parts.
[0015] The working principle of this utility model is as follows: the scraper to be tested is placed above the positioning groove between two sets of limiting posts, so that the back of the blade contacts the push block. The pushing mechanism presses one side of the blade edge against the side of the testing platform, simulating the force on the scraper when it is installed on the working equipment. This puts the scraper in the working installation state during testing, and the deformation of the scraper blade can be quickly checked by the contact state between the two. This improves the flatness detection accuracy of the scraper flatness, prevents false detection, and is simple and fast to operate, improving the safety and reliability of the test.
[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
