[0019] Compared with the related art, the positioning device for PCBA board processing provided by the utility model has the following beneficial effects:

[0020] The utility model provides a positioning device for PCBA board processing. In the PCBA board processing operation, when the positioning device is used to position the PCBA board, the clamp on the support plate is used to clamp the two sides of the PCBA board by tightening screws and the like, so that the PCBA board is stably fixed on the support plate, and then the upper surface of the PCBA board is processed. However, this operation will cause the following problems: in batch production, the clamp for positioning a single PCBA board needs to frequently perform disassembly and assembly operations of the PCBA board, resulting in low processing efficiency. When testing the PCB, the support plate angle cannot be adjusted, and the user may easily suffer physical strain if he lowers his head for a long time. By setting an adjustment structure, the adjustment tube is first rotated, and the adjustment tube moves along the support rod toward the direction close to the corresponding clamp plate with the help of a thread.

By setting an auxiliary structure, the auxiliary rod is first rotated, and the auxiliary rod drives the moving block to move along the inner wall of the base with the help of a thread. During the movement of the moving block toward the auxiliary frame, the moving block drives the connecting rod to move, and the connecting rod rotates to support the auxiliary frame upward, and the auxiliary frame drives the support plate to move upward. During this process, the support plate always slides along the round rod, and the support plate drives the positioning device and the circuit board to move upward, and the auxiliary rod is continued until the support plate is raised to a suitable height. Among them, the friction between the moving block and the inner wall of the base is reduced by a pulley, so that the moving block moves along the inner wall of the base more smoothly, and the auxiliary rod is rotated to support the support plate upward with the help of a connecting rod, so that the user can adjust the height of the clamped circuit board according to the workbench and his own height, and prevent the user from feeling uncomfortable when working with his head down for a long time.

Both ends of the sliding rod 412 are fixedly connected to the positioning frame 403. Two clamping plates 413 are fixedly connected to the positions of the movable plate 411 on both sides of the inner wall of the positioning frame 403 corresponding to the positions of the movable plate 411. A reserved groove 414 is provided on the side where the clamping plate 413 and the movable plate 411 are close to each other. The adjusting tube 410 is rotated to make the movable plate 411 move along the supporting rod 409, and the movable plate 411 and the clamping plate 413 are used to cooperate to position the circuit board 2. The limit plate 404 can be rotated to adjust the position.

An anti-skid groove 406 is provided on the side of the fixing plate 401 close to the limiting rod 405, and a plurality of anti-skid protrusions are fixedly connected to the inner wall of the anti-skid groove 406.

The two ends of the coil spring 408 are respectively fixedly connected to the fixed plate 401 and the positioning frame 403. When the positioning frame 403 rotates, the coil spring 408 always gives the positioning frame 403 a torsional force, so that the positioning frame 403 is more stable when rotating. The outer arc surface of the adjusting tube 410 is provided with a plurality of anti-slip grooves 415, and the plurality of anti-slip grooves 415 are evenly distributed on the adjusting tube 410. The friction of the arc surface of the adjusting tube 410 is increased by the anti-slip grooves 415, which is convenient for the user to rotate the adjusting tube 410.

[0032] In the embodiments of the present invention, please refer to Figure 5The auxiliary structure 5 includes an auxiliary rod 51, which is rotatably connected to the base 3, and the arc surface of the auxiliary rod 51 is threadedly connected with a moving block 52, and the moving block 52 is slidably connected to the inner wall of the base 3. The upper end of the moving block 52 is rotatably connected with a connecting rod 53, and the end of the connecting rod 53 away from the moving block 52 is rotatably connected to an auxiliary frame 54, and the auxiliary frame 54 is fixedly connected to the lower surface of the support plate 1. Two round rods 55 are fixedly connected to the upper surface of the base 3, and the arc surface of the round rod 55 is slidably connected to the support plate 1. By rotating the auxiliary rod 51, the supporting plate 1 is supported upward with the help of the connecting rod 53, which is convenient for the user to adjust the height of the clamped circuit board 2 according to the workbench and his own height, and prevents the user from feeling uncomfortable when working with his head down for a long time. Several pulleys 56 are rotatably connected to both sides of the moving block 52, and the arc surfaces of the several pulleys 56 are slidably connected to the base 3. The pulleys 56 reduce the friction between the moving block 52 and the inner wall of the base 3, so that the moving block 52 moves more smoothly along the inner wall of the base 3.

[0033] The working principle of the positioning device for PCBA board processing provided by the utility model is as follows: by setting the adjustment structure 4, the adjustment tube 410 is first rotated, and the adjustment tube 410 moves along the support rod 409 toward the direction close to the corresponding clamping plate 413 with the help of the thread, and the adjustment tube 410 drives the moving plate 411 to move toward the direction close to the clamping plate 413. During this process, the moving plate 411 always moves along the sliding rod 412. After adjusting the moving plate 411 and the clamping plate 413 to a suitable spacing according to the width size of the circuit board 2, multiple circuit boards 2 are arranged and placed on the clamping plate 4 13 and the reserved groove 414 on the movable plate 411, and then continue to rotate the adjusting tube 410 until the movable plate 411 cooperates with the clamping plate 413 to position the multiple circuit boards 2. When it is necessary to adjust the inclination angle of the clamped circuit board 2, first rotate the limiting rod 405, and the limiting rod 405 moves along the limiting plate 404 in the direction away from the fixed plate 401 with the help of the thread, release the limit of the rotating shaft 402, rotate the limiting rod 405, and the limiting plate 404 drives the positioning frame 403 to rotate through the rotating shaft 402, thereby rotating the clamped circuit board 2, and wait for When the tilt angle is adjusted to a suitable level, the limit rod 405 is rotated in the opposite direction, and the limit rod 405 moves toward the direction close to the fixed plate 401 until the limit rod 405 squeezes the fixed plate 401 to stop the rotation of the shaft 402. The anti-skid groove 406 increases the friction between the fixed plate 401 and the limit rod 405, so that the limiting effect of the limit rod 405 is better. The limit plate 404 is driven to rotate by operating the handle 407, and then the rotation shaft 402 and the positioning frame 403 are driven to rotate, so that the user can rotate the limit plate 404. When the positioning frame 403 rotates, The coil spring 408 always gives a torsional force to the positioning frame 403, making the positioning frame 403 more stable when rotating. The anti-slip pattern 415 increases the friction of the arc surface of the adjusting tube 410, making it convenient for the user to rotate the adjusting tube 410, thereby achieving the goal of rotating the adjusting tube 410 to move the movable plate 411 along the support rod 409, and positioning the circuit board 2 by utilizing the movable plate 411 and the clamping plate 413. The inclination angle of the clamped circuit board 2 can be adjusted by rotating the limit plate 404, which is suitable for clamping circuit boards 2 of various sizes and positioning multiple circuit boards 2 at the same time.

[0034] By setting up the auxiliary structure 5, the auxiliary rod 51 is first rotated, and the auxiliary rod 51 drives the moving block 52 to move along the inner wall of the base 3 with the help of the thread. During the movement of the moving block 52 toward the direction close to the auxiliary frame 54, the moving block 52 drives the connecting rod 53 to move, and the connecting rod 53 rotates to support the auxiliary frame 54 upward, and the auxiliary frame 54 drives the support plate 1 to move upward. During this process, the support plate 1 always slides along the round rod 55, and the support plate 1 drives the positioning device and the circuit board 2 to move upward, and continues the auxiliary rod 51 until the support plate 1 is raised to a suitable height. Among them, the pulley 56 is used to reduce the friction between the moving block 52 and the inner wall of the base 3, so that the moving block 52 moves along the inner wall of the base 3 more smoothly, thereby achieving that by rotating the auxiliary rod 51, the supporting plate 1 is supported upward by the connecting rod 53, so that the user can adjust the height of the clamped circuit board 2 according to the workbench and his own height, and prevent the user from feeling uncomfortable when working with his head down for a long time.
