Technical Field
[0001] The utility model relates to the technical field of flatness inspection tooling, in particular to a flatness defect inspection tooling for a plate product. Background Art
[0002] When processing circuit boards and other board materials, due to the development of electronic products towards miniaturization and integration, electronic manufacturers now use continuous board production for the production of circuit boards. After the patch test and other processes are completed, they are separated and packaged for shipment. There are high requirements for the flatness of the board. How to inspect the flatness of a single product after the separation is a difficult problem that plagues electronic processing plants. The conventional inspection method is to use three-dimensional imaging for inspection. However, this method has high equipment investment costs and is not very efficient. In addition, there are some special flatness inspection equipment, but general inspection equipment can only detect the flatness of one side of the board first, and then the other side again. The inspection efficiency is low and it is difficult to meet the needs of rapid inspection of large quantities of workpieces. To this end, we propose a flatness defect detection tool for board products. Utility Model Content

DETAILED DESCRIPTION
[0017] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0018] like Figure 1-3 As shown, the utility model is a flatness defect detection tool for a plate product, comprising a base 1, a clamping bracket 11 is arranged on the top of the base 1, a limiting screw 12 is screwed to the side of the clamping bracket 11, and a clamping plate 13 in contact with two ends of the plate 27 is movably connected to the inner side of the limiting screw 12. By arranging the clamping bracket 11 on the top of the base 1, and correspondingly arranging the limiting screw 12 and the clamping plate 13 on both sides of the clamping bracket 11, the limiting screw 12 is rotated to drive the clamping plate 13 to move horizontally so that the two ends of the plate 27 can be clamped and fixed. Specifically, the width of the clamping bracket 11 is smaller than the width of the plate 27, so it will not affect the detection process of the plate 27.
[0019] The side of the clamping bracket 11 is provided with a mounting seat 14 with a slide groove 15 on the top, a screw rod 16 is provided in the slide groove 15, and the screw rod 16 is screwed to the lower part of the movable plate 17, and a top plate 19 is provided on the top of the movable plate 17. The lower side of the top plate 19 is provided with a fixed detection plate 2. By providing the mounting seat 14, the slide groove 15, the screw rod 16, the movable plate 17 and the first hand wheel 18 and other structures, the movable plate 17 can be driven to move by rotating the first hand wheel 18, so that the movable detection plate 26 is connected to the fixed detection plate 26. The inspection plate 2 moves in a direction parallel to the plate 27 at the same time. During this process, if the flatness of both sides of the plate 27 is qualified, the first hand wheel 18 can rotate smoothly, and the mobile inspection plate 26 and the fixed inspection plate 2 respectively pass through the two sides of the plate 27. If there is a protrusion defect on the surface of the plate 27, when the mobile inspection plate 26 or the fixed inspection plate 2 contacts the protrusion, the rotation of the first hand wheel 18 will have an obvious sense of blockage. The user can quickly judge whether the plate 27 is qualified, thereby achieving the purpose of quickly performing flatness detection on the plate 27 product.
[0020] A limit seat 22 is provided at the lower side of the top plate 19, a threaded shaft 23 is screwed on the limit seat 22, a reinforcing bracket 25 is movably connected to the end of the threaded shaft 23, and a movable detection plate 26 is fixed to the side of the reinforcing bracket 25. By providing the limit seat 22, the threaded shaft 23, the second hand wheel 24, the reinforcing bracket 25 and other structures, the position of the movable detection plate 26 can be automatically adjusted, so that the spacing between the movable detection plate 26 and the fixed detection plate 2 can be adjusted, and the movable detection plate 26 cooperates with the fixed detection plate 2 to abut against the two sides of the plate 27 at the same time, so that the plate 27 can be conveniently detected.
[0021] In the above solution, the screw rod 16 is rotatably connected to the mounting seat 14 , and a first hand wheel 18 is provided at the end of the screw rod 16 .
[0022] In the above solution, the front side of the top plate 19 is provided with scale lines 21 , and the setting of the scale lines 21 can facilitate the user to observe the distance between the fixed detection plate 2 and the movable detection plate 26 .
[0023] In the above solution, the “0” scale position of the scale line 21 is in the same plane as the inner wall of the fixed detection plate 2 .
[0024] In the above scheme, a second hand wheel 24 is fixed to the outer end of the threaded shaft 23. The threaded shaft 23 is driven to rotate by rotating the second hand wheel 24, and the threaded shaft 23 and the limit seat 22 produce relative movement. The end of the threaded shaft 23 pushes the mobile detection plate 26 toward the fixed detection plate 2 through the reinforcing bracket 25.
[0025] In the above solution, the top of the reinforcing bracket 25 is clamped in the groove at the bottom of the top plate 19, and the reinforcing bracket 25 can slide horizontally in the groove, thereby ensuring the stability of the mobile detection plate 26 during the movement.
[0026] In the above solution, the bottom end of the movable plate 17 is movably engaged in the slide groove 15 .
[0027] Working principle:
[0028] When using this type of flatness defect detection tool for plate products, the end of the plate 27 to be detected is placed in the clamping bracket 11, and then the limiting screw 12 is manually rotated so that the clamping plate 13 simultaneously presses and fixes it from both sides of the plate 27. At this time, one side surface of the plate 27 is in contact with the inner wall of the fixed detection plate 2, and then the second hand wheel 24 is manually rotated to drive the threaded shaft 23 to rotate, and the threaded shaft 23 and the limiting seat 22 are relatively moved. The end of the threaded shaft 23 pushes the mobile detection plate 26 toward the fixed detection plate 2 through the reinforcing bracket 25, and the mobile detection plate 26 cooperates with the fixed detection plate 2 to abut against the two side surfaces of the plate 27 at the same time. When detecting, use The user can drive the movable plate 17 to move by rotating the first hand wheel 18, so that the movable detection plate 26 and the fixed detection plate 2 move in a direction parallel to the plate 27 at the same time. During this process, if the flatness of both sides of the plate 27 is qualified, the first hand wheel 18 can rotate smoothly, and the movable detection plate 26 and the fixed detection plate 2 pass through the two sides of the plate 27 respectively. If there is a protrusion defect on the surface of the plate 27, there will be an obvious blockage in the rotation of the first hand wheel 18 when the movable detection plate 26 or the fixed detection plate 2 contacts the protrusion, indicating that the flatness of the plate 27 is unqualified. By repeating the above detection process for different plates 27, the purpose of quickly performing flatness detection on the plate 27 product is achieved.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
