Description

A clamping device for the inspection and positioning of electronic components on a circuit board. Technical Field

[0001] This utility model relates to the technical field of circuit board detection and positioning clamping devices, specifically a clamping device for detecting and positioning electronic components on circuit boards. Background Technology

[0002] In the modern electronics industry, circuit boards are a core component of various electronic devices. Numerous electronic components are integrated on circuit boards, and the proper functioning of these components directly affects the performance and reliability of the entire electronic device. Therefore, testing the electronic components on circuit boards is a crucial step in ensuring the quality of electronic devices.

[0003] The utility model patent application with publication number "CN216434157U" discloses a clamping device for the detection and positioning of electronic components on a circuit board, relating to the field of circuit board inspection fixture technology. It includes: a base, a support rod, a lifting cavity, a lower clamping frame, a second crossbar, a fourth bearing, and an upper clamping frame. A support rod is fixedly connected to the left side of the upper surface of the base; a lifting cavity is fixedly connected to one side inside the support rod; and the lower clamping frame is movably connected to one end of the right side of the support rod. The beneficial effect is that by rotating a rocker arm, the rocker arm drives a second gear to rotate through a through hole, which in turn drives a first gear to rotate, which in turn drives a threaded screw to rotate. This allows a slider to move horizontally up and down on the threaded screw. Simultaneously, the slider drives the first crossbar and the lower clamping frame to move horizontally up and down, thereby adjusting the distance between the lower and upper clamping frames. This allows the lower and upper clamping frames to clamp and fix circuit boards of various sizes.

[0004] The clamping device for detecting and positioning electronic components on circuit boards disclosed in the above document has the following defects: the technical solution only sets up a single rotating mechanism, which is prone to over-rotation during the rotation process. Due to the lack of an effective limiting mechanism, when the clamping mechanism drives the circuit board to rotate, once it exceeds the predetermined angle, it may cause the circuit board to lose control of its position. It is necessary to manually support it continuously to ensure that the circuit board is in the correct detection position, which makes the operation process inconvenient.

[0005] Therefore, it can be seen that the existing clamping devices for the detection and positioning of electronic components on circuit boards do not have a structure that facilitates the limiting of the rotating clamping mechanism. It is necessary to improve the existing shortcomings and provide a clamping device for the detection and positioning of electronic components on circuit boards. Summary of the Invention

[0006] The purpose of this utility model is to provide a clamping device for the detection and positioning of electronic components on a circuit board. This device solves the problem that the existing technology only has a single rotating mechanism, which is prone to over-rotation during the rotation process. Due to the lack of an effective limiting mechanism, when the clamping mechanism drives the circuit board to rotate, once it exceeds the predetermined angle, it may cause the circuit board to lose its position. It requires continuous manual support to ensure that the circuit board is in the correct detection position, which makes the operation process inconvenient.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a clamping device for detecting and positioning electronic components on a circuit board. It includes a base plate, a bracket fixedly mounted on the upper surface of the base plate, a screw rotatably connected inside the bracket, a worm gear fixedly mounted on the circumferential side of the screw, a handle rotatably connected inside the bracket, one end of the handle extending into the bracket, and a worm gear fixedly mounted on one end of the handle. The worm gear and the worm gear mesh with each other. A movable plate slidably connects inside the bracket, and the movable plate is threadedly connected to the outer surface of the screw. A fixed plate is fixedly mounted on one end of the bracket. Clamping mechanisms are rotatably connected inside both the movable plate and the fixed plate. Several sets of slots are formed on the upper surface of the movable plate. A limiting mechanism is fixedly mounted on the outer surface of one set of clamping mechanisms, and the insertion end of the limiting mechanism is inserted into the corresponding slot.

[0009] Furthermore, the limiting mechanism includes a positioning plate, which is fixedly installed on the outer surface of the clamping mechanism. Several sliding grooves are formed on the peripheral side of the positioning plate. A spring is fixedly installed on the upper surface of the positioning plate. A movable cylinder is provided on the peripheral side of the positioning plate. Several sets of sliders are fixedly installed inside the movable cylinder. The sliders are slidably connected to the inside of the sliding grooves. The inner top of the movable cylinder is fixedly connected to one end of the spring. A positioning rod is fixedly installed on the lower surface of the movable cylinder. The positioning rod is inserted into the inside of the slot.

[0010] Furthermore, the clamping mechanism includes a rotating rod, and the rotating rod is rotatably connected inside both the moving plate and the fixed plate. A positioning plate is fixedly installed on the outer surface of one set of the rotating rods, and a placement shell is fixedly installed at one end of the rotating rod. Guide slide rods are slidably connected inside both ends of the placement shell.

[0011] Furthermore, the internal thread of the housing is connected to an adjusting rod.

[0012] Furthermore, one end of the adjusting rod is rotatably connected to a clamping plate.

[0013] Furthermore, one end of each guide slide rod is fixedly installed to the outer surface of the clamping plate.

[0014] This utility model has the following beneficial effects:

[0015] When the circuit board needs to be rotated, this invention allows the movable cylinder to slide inside the groove via a slider by pulling it upwards. Simultaneously, the movable cylinder stretches a spring, which provides a restoring force. The movable cylinder then pulls the positioning rod out of the slot, releasing the limiting mechanism's restriction on one set of clamping mechanisms. Next, the placement shell is moved; since the circuit board is clamped between the two placement shells, they rotate synchronously. When the placement shell reaches the appropriate position, the movable cylinder is released, causing the spring to return and the movable cylinder to reset. The reset movable cylinder then drives the positioning rod to insert into the corresponding slot, thus limiting the clamping mechanism. This avoids the problem of existing technologies with only a single rotating mechanism, which can easily cause the clamping mechanism to over-rotate the circuit board, requiring continuous manual assistance and causing inconvenience.

[0016] The guide slide rod of this invention provides guidance and support for the movement of the clamping plate, thereby improving the stability of the movement. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6. This utility model is a clamping device for detecting and positioning electronic components on a circuit board. It includes a base plate 1, a bracket 2 fixedly mounted on the upper surface of the base plate 1, a screw 4 rotatably connected inside the bracket 2, a worm gear 5 fixedly mounted on the circumferential side of the screw 4, a handle 6 rotatably connected inside the bracket 2, one end of the handle 6 extending into the interior of the bracket 2, a worm 7 fixedly mounted on one end of the handle 6, the worm 7 and the worm gear 5 meshing and connecting, a movable plate 8 slidably connected inside the bracket 2, the movable plate 8 and the outer surface of the screw 4 threadedly connected, a fixed plate 3 fixedly mounted on one end of the bracket 2, a clamping mechanism 9 rotatably connected inside both the movable plate 8 and the fixed plate 3, and a number of slots 801 opened on the upper surface of the movable plate 8, one of which a limiting mechanism 10 is fixedly mounted on the outer surface of the clamping mechanism 9, the insertion end of the limiting mechanism 10 and the corresponding slot 801 are inserted into each other.

[0026] When it is necessary to clamp the circuit board, first place the circuit board inside the placement shell 902 located on the moving plate 8, then turn the handle 6. The handle 6 drives the worm wheel 5 to rotate through the worm 7. The worm wheel 5 drives the screw 4 to rotate. The screw 4 is threadedly connected to the moving plate 8, thereby moving the moving plate 8.

[0027] The limiting mechanism 10 includes a positioning plate 1001, which is fixedly installed on the outer surface of the clamping mechanism 9. Several sliding grooves 1002 are opened on the peripheral side of the positioning plate 1001. A spring 1003 is fixedly installed on the upper surface of the positioning plate 1001. A movable cylinder 1004 is provided on the peripheral side of the positioning plate 1001. Several sets of sliders 1005 are fixedly installed inside the movable cylinder 1004. The sliders 1005 are slidably connected to the inside of the sliding grooves 1002. The inner top of the movable cylinder 1004 is fixedly connected to one end of the spring 1003. A positioning rod 1006 is fixedly installed on the lower surface of the movable cylinder 1004. The positioning rod 1006 is inserted into the inside of the slot 801.

[0028] When the circuit board needs to be rotated, the movable cylinder 1004 is pulled upwards. The movable cylinder 1004 slides inside the slide groove 1002 via the slider 1005. As the movable cylinder 1004 moves, the spring 1003 is stretched. The spring 1003 provides a rebound force to the movable cylinder 1004. Then, the movable cylinder 1004 pulls the positioning rod 1006 out from the inside of the slot 801, which releases the limitation mechanism 10 on one of the clamping mechanisms 9. Then, the placement shell 902 is moved. Since the circuit board is clamped between the two placement shells 902, the placement shell 902 will rotate synchronously. When it rotates to the appropriate position, the movable cylinder 1004 is released, which causes the spring 1003 to rebound, thereby resetting the movable cylinder 1004. The reset of the movable cylinder 1004 drives the positioning rod 1006 to insert into the corresponding slot 801, which can limit the clamping mechanism 9. This avoids the situation in the prior art where there is only a single rotating mechanism, which is prone to causing the clamping mechanism 9 to rotate the circuit board excessively, resulting in the need for continuous manual support.

[0029] The clamping mechanism 9 includes a rotating rod 901, and the rotating rod 901 is rotatably connected inside the moving plate 8 and the fixed plate 3. A positioning plate 1001 is fixedly installed on the outer surface of one set of rotating rods 901, and a placement shell 902 is fixedly installed at one end of the rotating rod 901. Guide slide rods 903 are slidably connected inside both ends of the placement shell 902.

[0030] An adjusting rod 904 is threadedly connected to the inside of the housing 902;

[0031] One end of the adjusting rod 904 is rotatably connected to the clamping plate 905;

[0032] One end of each guide slide rod 903 is fixedly installed to the outer surface of the clamping plate 905;

[0033] When the upper side of the circuit board abuts against the inside of the placement shell 902 on the fixed plate 3 through the movement of the moving plate 8, the upper and lower sides of the circuit board can be positioned. Then, the adjusting rods 904 on the two sets of clamping mechanisms 9 are rotated. The adjusting rods 904 drive the clamping plate 905 to move forward. The clamping plate 905 drives the guide slide rod 903 to slide inside the placement shell 902. The guide slide rod 903 provides guidance and support for the movement of the clamping plate 905, thereby improving the stability of the movement. Then the circuit board can be fixed.

[0034] When using the circuit board, first place the circuit board inside the placement shell 902 on the movable plate 8. Then rotate the handle 6. The handle 6 drives the worm wheel 5 to rotate through the worm gear 7. The worm wheel 5 drives the screw 4 to rotate. The screw 4 is threadedly connected to the movable plate 8, thereby moving the movable plate 8. When the upper side of the circuit board abuts against the placement shell 902 on the fixed plate 3 through the movement of the movable plate 8, the upper and lower sides of the circuit board can be positioned. Then rotate the adjusting rods 904 on the two sets of clamping mechanisms 9. The adjusting rods 904 drive the clamping plate 905 to move forward. The clamping plate 905 drives the guide slide rod 903 to slide inside the placement shell 902. The guide slide rod 903 provides guidance and support for the movement of the clamping plate 905, thereby improving the stability of the movement. Then the circuit board can be fixed.

[0035] When the circuit board needs to be rotated, the movable cylinder 1004 is pulled upwards. The movable cylinder 1004 slides inside the slide groove 1002 via the slider 1005. As the movable cylinder 1004 moves, the spring 1003 is stretched. The spring 1003 provides a restoring force to the movable cylinder 1004. Then, the movable cylinder 1004 pulls the positioning rod 1006 out of the slot 801, thereby releasing the limitation mechanism 10 on one of the clamping mechanisms 9. Then, the placement shell 902 is moved. Since the circuit board is clamped between the two placement shells 902, the placement shells 902 will rotate synchronously. When it rotates to the appropriate position, the movable cylinder 1004 is released, causing the spring 1003 to return and the movable cylinder 1004 to reset. The reset of the movable cylinder 1004 causes the positioning rod 1006 to insert into the corresponding slot 801, thereby limiting the clamping mechanism 9. This avoids the situation in the prior art where there is only a single rotating mechanism, which is prone to causing the clamping mechanism 9 to rotate the circuit board excessively, resulting in the need for continuous manual support.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
