Description

Technical Field

[0001] The present invention relates to the technical field of industrial product detection, in particular to an automatic transformation optical detection angle fixture and an angle detection device. Background Art

[0002] In order to meet the demand of being able to quickly change the angle after one clamping to detect different angles of the same product in the industrial production process. At present, the method commonly used on the market is to manually place the product on a test blister tray with a fixed angle, and then test the part that can be measured at the current product placement angle. After the test, the product is taken out and placed on another test blister tray with a fixed angle to test the part that can be measured at another placement angle. This method requires a huge amount of human resources, a long product testing cycle, and high costs, which cannot meet the needs of lean production. Therefore, in order to improve product testing efficiency, realize the ability of products to automatically change placement angles, reduce labor, and improve testing efficiency, it is urgently needed to design an automatic optical detection angle change fixture. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a fixture and a corresponding detection device that can realize the rapid change of angles of a product after one clamping to detect the functions of detection parts at different angles of the same product.

[0004] In order to achieve the above-mentioned purpose, first, the present invention designs an automatic optical detection angle change fixture, including a main body; a plurality of rotating bars for fixing workpieces, which are rotatably connected to the main body, and a plurality of magnets are provided on the rotating bars; a plurality of magnet bars, which are connected to the main body by plunger screws; a plurality of limit blocks, which are installed at the bottom of the main body and cooperate with the rotating bars; the bottom of the magnet of the rotating bar is trapezoidal or conical, and the limit block is provided with a limit slot that cooperates with the rotating bar magnet, so that the magnet slides in the limit slot; by adjusting the position of the magnet bar, the magnet bar repels or attracts the rotating bar magnet, and then drives the rotating bar magnet to rotate clockwise or counterclockwise. During the rotation process, the left side or right side of the rotating bar fits into the surface of the limit block, thereby forming a fixed and maintained angle for the rotating bar.

[0005] The present invention also has the following preferred technical solutions:

[0006] 1. A limiting portion is provided above the magnet on the rotating bar, and the limiting portion cooperates with the limiting notch to limit the rotation angle of the rotating bar.

[0007] 2. The limiting portion cooperates with the limiting notch to make the rotation angle of the rotating bar smaller than the maximum angle that the magnet bar can make the rotating bar rotate.

[0008] The present invention also includes a detection device for automatically changing the optical detection angle developed corresponding to the above-mentioned fixture. On the basis of the above-mentioned automatic optical detection angle changing fixture, it also includes an angle changing mechanism, and the automatic optical detection angle changing fixture is installed on the angle changing mechanism.

[0009] Furthermore, the angle conversion mechanism includes a first rotary clamping cylinder and a second rotary clamping cylinder for clamping the automatic optical angle conversion fixture, and a first pushing cylinder and a second pushing cylinder connected to the magnet bar.

[0010] At the same time, the detection angle transformation method of the above detection device is as follows:

[0011] a. Place the automatic angle change detection fixture into the angle change mechanism. The first and second rotary clamping cylinders press the automatic angle change detection fixture tightly. The first push cylinder extends, pushing the magnet bar on the automatic angle change detection fixture to the right by a set distance. The plunger screws at both ends sink into the holes on the magnet bar, fixing the position of the magnet bar. Even after the push cylinders are retracted, the position of the magnet bar remains unchanged. The magnets on the rotating bar attract each other, causing the rotating bar to rotate counterclockwise. During the rotation process, the left side of the rotating bar fits against the surface of the limit block, thus forming a fixed and maintained angle. The angle that can be rotated by the attraction of the magnets is greater than the fixed angle. Since the product is fixed in the hole of the rotating bar, the product will also form a set test angle.

[0012] b. Place the automatic angle change detection fixture into the angle change mechanism. The first rotary clamping cylinder and the second rotary clamping cylinder press the automatic angle change detection fixture. The second push cylinder extends to push the magnet bar on the automatic angle change detection fixture to the left by a set distance. The plunger screws at both ends are embedded in the holes on the magnet bar to fix the position of the magnet bar. The rotating bar magnets are attracted to the magnet bar to rotate the rotating bar clockwise. During the rotation process, the right side of the rotating bar fits with the surface of the limit block, thereby forming a fixed and maintained angle for the rotating bar. The angle that the magnets can rotate by attraction is greater than the fixed angle, and the product is fixed in the acupuncture points of the rotating bar, and the product will also form a set test angle.

[0013] Advantageous Effects of the Invention

[0014] The advantages of the automatic angle-changing optical inspection fixture provided by the present invention include, but are not limited to: The novel structural design utilizes a magnet bar and a magnet at the bottom of the rotating bar to achieve angle change and retention. In actual use, the fixture demonstrates stable functionality, simple and reliable operation, and high efficiency in angle-changing product testing. Compared to manual multiple placement and testing methods, it significantly improves production capacity and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions adopted in the present invention are further described below through examples and drawings to help those skilled in the art better understand the present invention.

[0022] See also Figure 2 , a specific embodiment of the present invention's automatic angle-changing optical inspection fixture, comprises a main body 11, which is a frame. A rotating bar 12 is mounted within the main body. The rotating bar 12 is connected to both sides of the main body 11 and a crossbeam in the middle via a rotating shaft, allowing the rotating bar 12 to rotate on the main body. On either side of the main body, a magnet bar 13 is located at one end of each rotating bar, perpendicular to the rotating bar 12. The magnet bar 13 is fixed to the main body, which also has a stopper 14 fixed to it, also perpendicular to the rotating bar 12.

[0023] See also Figure 3 In this embodiment, the magnet bar 13 and the rotating bar 12 are not in contact with each other. The rotating bar 12 is provided with a magnet 121. The magnet bar 13 and the magnet 121 on the rotating bar 12 attract or repel each other, so that the rotating bar 12 can rotate according to the change of the position of the magnet bar 13.

[0024] See also Figure 4 When the rotating bar 12 rotates to a certain angle according to the change in the position of the magnet bar 13, a limiting slot is provided on the limiting block 14 in contact with the bottom of the rotating bar 12 corresponding to the bottom of the rotating bar. The bottom of the rotating bar 12 is a trapezoidal structure, which can slide conveniently in the limiting slot. The upper part of the trapezoidal structure is a limiting part. When it is rotated to a certain tilt angle, the limiting part clamps the limiting slot to complete the limiting of the rotating bar.

[0025] See also Figure 5 In order to change the position of the magnet bar 13, the magnet bar 13 is connected to the main body 11 by a plunger screw 15. The plunger screw 15 includes a spring 151 and a ball 152. The magnet bar 13 is provided with a plurality of grooves 131 that cooperate with the ball 152. When the magnet bar is pushed by an external force, the ball rolls out from one groove, rolls to another groove, and then the magnet bar is fixed by a spring limiter.

[0026] See also Figure 1 The above-mentioned automatic optical detection angle changing fixture 1 is installed on the angle changing mechanism 2. The angle changing mechanism includes a first rotary clamping cylinder 21 and a second rotary clamping cylinder 22 for clamping the optical detection angle fixture. On both sides of the optical detection angle fixture, a first pushing cylinder and a second pushing cylinder connected to the magnet bar 13 are respectively provided to push the magnet bar to both sides.

[0027] The present invention will be further described below through the use of embodiments.

[0028] Place the automatic angle change detection fixture into the angle change mechanism. The first rotary clamping cylinder and the second rotary clamping cylinder press the automatic angle change detection fixture tightly. The first push cylinder extends, pushing the magnet bar on the automatic angle change detection fixture to the right for a distance. The plunger screws at both ends sink into the holes on the magnet bar, fixing the position of the magnet bar. This way, the position of the magnet bar will not change even after the push cylinder is retracted. The magnets on the rotating bar attract the magnet bar, causing the rotating bar to rotate counterclockwise. During the rotation process, the left side of the rotating bar fits into the surface of the limit block, thereby forming a fixed and maintained angle for the rotating bar. The angle that can be rotated by the magnets of the rotating bar and the magnet bar should be greater than the fixed angle. The product is fixed in the acupuncture points of the rotating bar, so the product will also form a specific test angle.

[0029] When the angle needs to be adjusted to the other side, the second push cylinder extends, pushing the magnet bar on the automatic angle change detection fixture a certain distance to the left. The plunger screws at both ends sink into the holes in the magnet bar, fixing the magnet bar in place. The magnets on the rotating bar attract the magnet bar, causing the rotating bar to rotate clockwise. During rotation, the right side of the rotating bar mates with the surface of the limit block, thus forming a fixed and maintained angle. The product is fixed in the hole of the rotating bar, and the product also forms another specific test angle.

[0030] The design provided by this invention can significantly reduce production costs. For example, in one project, the previous testing method required two production lines, two AOI testers, and six personnel. However, with this design, only one production line, one supporting AOI tester, and three personnel were required, saving approximately 300,000 yuan in equipment costs and nearly 250,000 yuan in labor costs for the entire project.

[0031] The automatic angle-changing optical inspection fixture used in this invention features a novel structural design, utilizing magnetic force to achieve both angle change and retention. In actual use, it demonstrates stable functionality, simple and reliable operation, and highly efficient angle-changing product testing, significantly improving productivity compared to manual, multiple placement tests.

[0032] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent replacement or change made by any technician familiar with the technical field within the technical scope disclosed by the present invention based on the technical solution and novel concept of the present invention should be covered by the scope of protection of the present invention.
