Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection, in particular to an auxiliary fixture of an optical detector for circuit boards. Background Art

[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout; circuit boards can be called printed circuit boards or printed circuit boards; circuit board optical testers are also called online circuit repair testers and circuit repair testers, which are general-purpose circuit board fault detection equipment.

[0003] However, the existing processing equipment has the following shortcomings:

[0004] Users usually place circuit boards on the surface of the material board for testing at random. When the circuit boards are placed at random, the equipment is prone to shaking, exerting force on the circuit boards, causing the circuit boards to slide out of the material board and contact the ground, causing contamination on the surface of the circuit boards and making them unusable; the clamping plate is difficult to clamp circuit boards of different sizes, making it difficult for the equipment to clamp and test circuit boards of different models, thereby reducing the equipment's ability to clamp different circuit boards.

[0005] Therefore, we propose an optical inspection instrument auxiliary fixture for circuit boards to solve the above problems. Utility Model Content

[0006] The utility model aims to solve the defect of circuit board limit stability in the prior art and proposes an auxiliary fixture of an optical detector for circuit boards.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an optical detector auxiliary clamp for circuit boards, comprising a main body and a clamping device, the upper surface of the main body is fixedly connected to a placement plate, the upper surface of the placement plate is fixedly connected to a connecting arm, the upper surface of the placement plate is provided with a material plate, a camera is provided inside the connecting arm, the clamping device is provided on the surface of the material plate, the clamping device comprises a connecting block and a connecting plate, the connecting block is fixedly connected to the upper surface of the material plate, the connecting plate is slidably connected to the inner wall of the connecting block, one end of the connecting plate is fixedly connected to a first clamping plate, the surface of the first clamping plate is provided with a second clamping plate, and the side of the connecting plate is fixedly connected to a protrusion.

[0008] Furthermore, a limiting plate is fixedly connected to the side of the second clamping plate, and a sliding rod is fixedly connected to the upper surface of the protrusion. By setting a limiting plate on the side of the second clamping plate, the second clamping plate can be shifted, thereby reducing the possibility of misalignment of the second clamping plate when the device is in use and causing the second clamping plate to detach from the first clamping plate.

[0009] Furthermore, the sliding rod is slidably connected to the surface of the limiting plate, one end of the sliding rod is fixedly connected to the limiting block, and the sliding rod is provided to facilitate limiting the limiting plate.

[0010] Furthermore, a first spring is fixedly connected to the surface of the limit block, and one end of the first spring away from the limit block is fixedly connected to the surface of the limit plate. The first spring is provided to facilitate applying a restoring elastic force to the limit plate.

[0011] Furthermore, an adjustment device is provided inside the connecting block, and the adjustment device includes an adjustment hole and a groove. The adjustment hole is opened on the surface of the connecting plate, and the groove is opened on the surface of the connecting block. A sliding hole is opened on the surface of the connecting block, and a pull plate is slidably connected to the inner wall of the groove. One end of the pull plate is fixedly connected to a second spring, and the end of the second spring away from the pull plate is fixedly connected to the inner wall of the groove. By opening the adjustment hole on the surface of the connecting plate, the adjustment rod can be restricted, so as to stabilize the connecting plate.

[0012] Furthermore, one end of the pull plate is fixedly connected to an adjusting rod, and the adjusting rod is slidably connected to the inner wall of the sliding hole. The pull plate is provided to facilitate the limiting linkage of the adjusting rod.

[0013] Furthermore, one end of the adjusting rod is clamped with the inner wall of the adjusting hole, and a pull handle is fixedly connected to the connection between the adjusting rod and the pull plate. The pull handle is provided to facilitate the movement of the pull plate.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, when testing the circuit board, the tester places the circuit board to be tested on the surface of the material board, then starts the equipment, and the camera shoots and tests the surface of the circuit board. When clamping the circuit board, the second clamping plate is pulled to drive the first spring to displace and deform to generate elastic force, and then the second clamping plate is separated from the surface of the first clamping plate, and then the circuit board is placed between the first clamping plate and the second clamping plate, and then the restraint on the second clamping plate is released, and then the first spring is reset to drive the second clamping plate to combine with the first clamping plate to clamp the circuit board. By setting up the clamping device, the circuit board is effectively clamped, and the circuit board is quickly clamped, which reduces the time when the equipment is in use. Users generally place the circuit board on the surface of the material board for testing at will. When the circuit board is placed at will, the equipment is prone to shaking, and force is applied to the circuit board, causing the circuit board to slide out of the material board and contact the ground, causing pollution to the surface of the circuit board and making it unusable, thereby improving the stability of the equipment to the circuit board.

[0016] 2. In the utility model, by setting an adjustment device, before using the equipment, the user pulls the handle, and when the handle moves, it drives the pull plate to move, and the movement of the pull plate drives the adjustment rod to move, and the adjustment rod moves out of the inside of the adjustment hole, and when the pull plate moves, it drives the second spring to displace and deform to generate elastic force, and when the adjustment rod is out of the inside of the adjustment hole, the connecting plate is moved to adjust the first clamping plate and the second clamping plate. By setting the adjustment device, the clamping plate is effectively adjusted to play a role in adjusting the length of the clamping plate, which reduces the situation that the clamping plate is difficult to clamp circuit boards of different sizes when the equipment is in use, making it difficult for the equipment to clamp and detect circuit boards of different models, and improves the effect of the equipment on clamping different circuit boards.

[0024] The specific arrangement and function of the clamping device 6 and the adjusting device 7 will be described in detail below.

[0025] In this embodiment: the clamping device 6 is arranged on the surface of the material plate 5, and the clamping device 6 includes a connecting block 61 and a connecting plate 62. The connecting block 61 is fixedly connected to the upper surface of the material plate 5, and the connecting plate 62 is slidably connected to the inner wall of the connecting block 61. One end of the connecting plate 62 is fixedly connected to a first clamping plate 63, and a second clamping plate 64 is arranged on the surface of the first clamping plate 63. A protrusion 65 is fixedly connected to the side of the connecting plate 62.

[0026] Specifically, a side surface of the second clamping plate 64 is fixedly connected to a limiting plate 66 , and an upper surface of the protrusion 65 is fixedly connected to a sliding rod 67 .

[0027] In this embodiment: by providing a limit plate 66 on the side of the second clamping plate 64, the second clamping plate 64 can be shifted, which reduces the possibility of misalignment of the second clamping plate 64 when the device is in use, causing the second clamping plate 64 to separate from the first clamping plate 63.

[0028] Specifically, the slide rod 67 is slidably connected to the surface of the limit plate 66 , one end of the slide rod 67 is fixedly connected to the limit block 68 , and the slide rod 67 is provided to facilitate limiting the limit plate 66 .

[0029] Specifically, a first spring 69 is fixedly connected to the surface of the limit block 68 , and one end of the first spring 69 away from the limit block 68 is fixedly connected to the surface of the limit plate 66 . The first spring 69 is provided to facilitate applying a restoring elastic force to the limit plate 66 .

[0030] In this embodiment: an adjusting device 7 is provided inside the connecting block 61, and the adjusting device 7 includes an adjusting hole 71 and a groove 72. The adjusting hole 71 is provided on the surface of the connecting plate 62, and the groove 72 is provided on the surface of the connecting block 61. A sliding hole 73 is provided on the surface of the connecting block 61, and a pulling plate 74 is slidably connected to the inner wall of the groove 72. One end of the pulling plate 74 is fixedly connected to a second spring 76, and the end of the second spring 76 away from the pulling plate 74 is fixedly connected to the inner wall of the groove 72.

[0031] In this embodiment, by opening the adjustment hole 71 on the surface of the connecting plate 62 , the adjustment rod 75 can be restricted, thereby stabilizing the connecting plate 62 .

[0032] Specifically, one end of the pull plate 74 is fixedly connected to the adjusting rod 75 , and the adjusting rod 75 is slidably connected to the inner wall of the sliding hole 73 . The pull plate 74 is provided to facilitate the limiting linkage of the adjusting rod 75 .

[0033] Specifically, one end of the adjustment rod 75 is engaged with the inner wall of the adjustment hole 71 , and a pull handle 77 is fixedly connected to the connection between the adjustment rod 75 and the pull plate 74 . The pull handle 77 is provided to facilitate the movement of the pull plate 74 .

[0034] Working principle: when testing the circuit board, the tester places the circuit board to be tested on the surface of the material board 5, and then starts the equipment. The camera 4 shoots and tests the surface of the circuit board. When clamping the circuit board, the second clamping plate 64 is pulled to drive the first spring 69 to displace and deform to generate elastic force, and then the second clamping plate 64 is separated from the surface of the first clamping plate 63, and then the circuit board is placed between the first clamping plate 63 and the second clamping plate 64, and then the restraint on the second clamping plate 64 is released, and then the first spring 69 is reset to drive the second clamping plate 64 to combine with the first clamping plate 63 to clamp the circuit board. By setting the clamping device 6, the circuit board is effectively clamped, and the circuit board is quickly clamped, which reduces the equipment. When the user generally places the circuit board on the surface of the material board 5 for testing at will, when the circuit board is placed at will, the equipment is prone to shaking, and force is applied to the circuit board, causing the circuit board to slide out of the material board 5 and contact the ground, causing the surface of the circuit board to be contaminated and unable to be used, thereby improving the stability of the equipment to the circuit board.

[0035] Before using the device, the user pulls the pull handle 77. When the pull handle 77 moves, it drives the pull plate 74 to move. The movement of the pull plate 74 drives the adjustment rod 75 to move. The adjustment rod 75 moves out of the adjustment hole 71. When the pull plate 74 moves, it drives the second spring 76 to displace and deform to generate elastic force. When the adjustment rod 75 is out of the adjustment hole 71, the connecting plate 62 is moved to adjust the first clamping plate 63 and the second clamping plate 64. By setting the adjustment device 7, the clamping plate is effectively adjusted to play the role of adjusting the length of the clamping plate, which reduces the problem that the clamping plate is difficult to clamp circuit boards of different sizes when the device is in use, making it difficult for the device to clamp and detect circuit boards of different models, thereby improving the function of the device in clamping different circuit boards.
