Description

Technical Field

[0001] This utility model belongs to the field of automated testing technology, and in particular relates to an automatic detection device for the external dimensions of a module. Background Technology

[0002] During product manufacturing, the external dimensions of a module directly affect its assembly and performance. Dimensional deviations can prevent the module from being correctly installed in the equipment, affecting the overall structural stability and electrical connections, thereby reducing product reliability. Because modern manufacturing demands extremely high product dimensional accuracy and consistency, manual inspection is difficult to standardize and regulate throughout the entire process. Inconsistent inspection results may occur due to differences in operation, thus affecting the stability of product quality. Therefore, more and more production lines are adopting automated inspection equipment to improve inspection quality and production efficiency.

[0003] During the measurement process, it is necessary to ensure that the length and width of the module are aligned with the measurement reference. However, traditional automatic detection devices for module external dimensions often adopt a distributed detection process, that is, after completing the measurement in one direction, the module position is adjusted to perform the measurement in another direction. This distributed alignment method results in low detection efficiency. Therefore, an automatic detection device for module external dimensions is needed to solve the above problems.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] like Figures 1 to 4 As shown, this utility model embodiment provides an automatic module external dimension detection device, including:

[0026] The main body of the device 1 includes a worktable 11 and a pair of reference rods 12. The reference rods 12 are fixedly installed on the upper surface of the worktable 11, and one end of the pair of reference rods 12 is perpendicularly connected to each other. The upper surface of the reference rods 12 is provided with scale lines.

[0027] Alignment structure 2 includes an alignment block 21, a rotating block 22, a first fixing frame 23, a pair of limiting posts 24, and a spring 25. The alignment block 21 is movably mounted on the upper surface of the worktable 11 and positioned between the right angles formed by the pair of reference rods 12. The alignment block 21 has a 90-degree interior angle on the side facing the reference rods 12, and this interior angle is opposite to the right angle formed by the pair of reference rods 12. The side of the alignment block 21 away from the reference rods 12 is arc-shaped. The rotating block 22 has a fan-shaped cross-section and is rotatably mounted on the first fixing frame 23. The sidewall of the rotating block 22 is in contact with the arc-shaped sidewall of the alignment block 21. The pair of limiting posts 24 are rotatably mounted on the worktable 11, and their sidewalls are respectively in contact with the adjacent sidewalls of the alignment block 21. The two ends of the spring 25 are respectively connected to the upper surface of the alignment block 21 and the first fixing frame 23.

[0028] In this embodiment, the worker first places the module to be tested between a pair of reference rods 12 and an alignment block 21, ensuring that one of the right-angled sides of the module abuts against the inner wall of the pair of reference rods 12 forming a right angle. The rotating block 22 rotates, and the alignment block 21, which is in contact with the side wall of the rotating block 22, slides between a pair of limiting posts 24 until the inner corner of the alignment block 21 abuts against the other right-angled inner wall of the module, and the spring 25 is stretched. In this way, at the same time, the two opposite right angles of the module are abutted between the pair of reference rods 12 and the alignment block 21, improving the testing efficiency and eliminating the need for multiple alignment operations. Finally, the user can check whether the length of the adjacent side of the module meets the production requirements by observing the scale lines on the reference rods 12.

[0029] Specifically, the upper end of the rotating block 22 has a fixing rod 221, which is mounted on the first fixing frame 23 via a rotating shaft. The alignment structure 2 also includes a first driving member 26, which is mounted on the first fixing frame 23, and the output shaft of the first driving member 26 is connected to the fixing rod 221.

[0030] In this embodiment, after activation, the first driving member 26 drives the fixed rod 221 to rotate, thereby causing the rotating block 22 to rotate around the fixed rod 221 axially.

[0031] Specifically, the alignment block 21 has a moving groove 211 on its lower end face near the worktable 11, and the upper end face of the worktable 11 has a column 111 and a rotating ball 112. The rotating ball 112 is rotatably mounted on the upper end of the column 111, the column 111 is placed in the moving groove 211, and the rotating ball 112 is in contact with the inner wall of the moving groove 211.

[0032] In this embodiment, during the process of the alignment block 21 being moved by the rotating block 22, the relative position between the column 111 and the moving groove 211 changes, and the rotating ball 112 rotates on the inner wall of the moving groove 211. By setting the rotating ball 112, the friction between the column 111 and the alignment block 21 is reduced, and the service life of the equipment is extended.

[0033] Specifically, the main body 1 of the device also includes two sets of rotating columns 13, each set of rotating columns 13 is provided with multiple, the reference rod 12 forms a mounting groove 121 on the side wall near the alignment block 21, and the multiple rotating columns 13 of each set are rotatably and spaced apart in the mounting groove 121 on the side wall of each reference rod 12.

[0034] In this embodiment, by setting the rotating column 13, the frictional force during the movement of the module between a pair of reference rods 12 is reduced, thereby extending the service life of the equipment.

[0035] Specifically, the main body 1 of the device also includes a second fixing frame 14, a fixing cylinder 15 and a support plate 16. The fixing cylinder 15 is fixedly installed on the lower end face of the second fixing frame 14. The side wall of the fixing cylinder 15 forms a through groove 151 and a scale line. The upper end face of the support plate 16 has a plug-in post 161. The plug-in post 161 is slidably placed on the fixing cylinder 15. The second fixing frame 14 is fixedly installed on the worktable 11 and is positioned between the right angles formed by a pair of reference rods 12. The fixing cylinder 15 is positioned at a predetermined distance above the worktable 11.

[0036] Specifically, the main body 1 of the device also includes a pair of first connecting rods 17, a pair of second connecting rods 18, and a pair of second driving members 19. The pair of first connecting rods 17 and the pair of second connecting rods 18 are circumferentially distributed with the fixed cylinder 15 as the center. The upper end of the first connecting rod 17 is rotatably mounted on the second fixed frame 14. The two ends of the second connecting rod 18 are rotatably connected to the lower end of the first connecting rod 17 and the upper end of the abutment plate 16, respectively. The second driving members 19 are mounted on the second fixed frame 14, and the output shaft of each second driving member 19 is connected to each first connecting rod 17.

[0037] In this embodiment, after activation, the second driving member 19 drives one end of the first connecting rod 17 to rotate, causing the angle between the axial direction of the first connecting rod 17 and the second fixed frame 14 to change, thereby causing the angle between the axial direction of the first connecting rod 17 and the axial direction of the second connecting rod 18 to change, so that the abutment plate 16 at the lower end of the second connecting rod 18 abuts against the upper end surface of the module; during the rotation of the first connecting rod 17 and the second connecting rod 18, the insertion post 161 slides in the fixed cylinder 15, at which time the user can observe the scale line on the side wall of the fixed cylinder 15 through the through groove 151 to check whether the height of the module meets the production requirements; by setting the first connecting rod 17 and the second connecting rod 18, the abutment plate 16 is more stable during the downward movement, thereby ensuring the accuracy of the detection.

[0038] The working principle of this utility model is as follows:

[0039] When in use, the worker first places the module to be tested between a pair of reference rods 12 and an alignment block 21, and ensures that one of the right-angled sides of the module abuts against the inner wall of the pair of reference rods 12 forming a right angle. At this time, the side wall of the module is in contact with the side wall of the rotating column 13. By setting the rotating column 13, the friction force during the movement of the module between the pair of reference rods 12 is reduced, thereby extending the service life of the equipment.

[0040] Subsequently, the first driving component 26, after activation, drives the fixed rod 221 to rotate, which in turn causes the rotating block 22 to rotate axially around the fixed rod 221. At this time, the alignment block 21, which is in contact with the side wall of the rotating block 22, slides between a pair of limiting posts 24 until the inner corner of the alignment block 21 abuts against the other right-angled inner wall of the module. In this way, at the same time, the two opposite right angles of the module are abutted between a pair of reference rods 12 and the alignment block 21, respectively, improving detection efficiency and eliminating the need for multiple alignment operations. Finally, the user can check whether the length of the adjacent side of the module meets the production requirements by observing the scale lines on the reference rod 12.

[0041] During the process of the alignment block 21 being moved by the rotating block 22, the relative position between the column 111 and the moving groove 211 changes, and the rotating ball 112 rotates on the inner wall of the moving groove 211. By setting the rotating ball 112, the friction between the column 111 and the alignment block 21 is reduced, and the service life of the equipment is extended.

[0042] Then, after activation, the second drive unit 19 drives one end of the first connecting rod 17 to rotate, causing the angle between the first connecting rod 17 and the second fixed frame 14 to change, which in turn causes the angle between the first connecting rod 17 and the second connecting rod 18 to change, so that the abutment plate 16 at the lower end of the second connecting rod 18 abuts against the upper end face of the module. During the rotation of the first connecting rod 17 and the second connecting rod 18, the insertion post 161 slides in the fixed cylinder 15. At this time, the user can observe the scale lines on the side wall of the fixed cylinder 15 through the through groove 151 to check whether the height of the module meets the production requirements. By setting the first connecting rod 17 and the second connecting rod 18, the abutment plate 16 is more stable during the downward movement, thereby ensuring the accuracy of the detection.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
