Description

Technical Field

[0001] This utility model relates to the field of circuit board clamping technology, specifically to an electronic component clamp. Background Technology

[0002] In the manufacturing, testing and repair of electronic products, electronic components (especially circuit boards) need to be stably and precisely clamped and fixed for operations such as soldering, testing and debugging. Most clamps can only provide horizontal fixation and are difficult to adjust the circuit board to multiple angles (such as 90-degree flip) or rotation according to the operation requirements. Manual flipping is not only inefficient, but also easy to cause unstable clamping or damage to components. It is also inconvenient to fine-tune the position of the circuit board while it is clamped. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses an electronic component clamp. The technical solution adopted includes an outer frame, an inner frame, a stepper motor, an integrated connecting frame, a mounting slot, a rotary motor, a bidirectional lead screw, a mounting block, a front mounting box, a rear mounting box, a front adjustment mechanism, a front clamping shaft, a rear adjustment mechanism, and a rear clamping shaft. The stepper motor is fixedly installed at the center of the front side of the outer frame, and the output shaft of the stepper motor extends into the through hole at the center of the front side of the outer frame. The integrated connecting frame is integrally formed at the center of the front and rear sides of the inner frame. Shafts are fixed on both sides of the integrated connecting frame. The rear shaft is movably inserted into a blind hole on the inner wall of the rear side of the outer frame. The front shaft is fixedly connected to the output shaft of the stepper motor. The outer wall of the rear shaft contacts the inner wall of the blind hole. After the stepper motor is started, it can drive the entire inner frame to rotate or even flip, thereby realizing the adjustment of the circuit board clamped in the inner frame. Mounting slots are opened on both the front and rear sides of the inner frame, and horizontal adjustment mechanisms are installed in the mounting slots. The bidirectional lead screw is driven by a rotating motor mounted on the right side of the inner frame, which fits into the mounting slot. The mounting slots on the left and right sides are symmetrically fitted onto the bidirectional lead screw. The inner protruding parts of the mounting blocks on the front and rear sides are integrally formed with front and rear mounting boxes, respectively. The front mounting box is equipped with a front adjustment mechanism that mounts the front clamping shaft, and the rear mounting box is equipped with a rear adjustment mechanism that mounts the rear clamping shaft. The front and rear clamping shafts clamp the front and rear sides of the circuit board. At the same time, the rear clamping shaft can rotate under the action of the rear adjustment mechanism, so that the circuit board can be moved left and right in the clamped state, and its position can be adjusted as needed. Regarding the installation of the bidirectional lead screw, its two ends are supported and installed by bearings set in the inner wall of the mounting slot. The output shaft of the rotating motor is rigidly connected to the right end of the bidirectional lead screw through a coupling (such as a flexible coupling or a perforated coupling) or by direct drive.

[0004] As a preferred technical solution of this utility model, the inner frame has through holes on the left and right sides, and the outer frame has studs installed on the left and right sides. The inner end of the studs extends into the through holes to lock and stabilize the inner frame, thereby increasing the stability of the inner frame when it is placed horizontally.

[0005] As a preferred embodiment of this utility model, the front adjustment mechanism includes a front clamping motor, a central rotating shaft, and a front mounting block. The rotating shaft is rotatably mounted at the center of the front mounting box. The output shaft of the front clamping motor mounted on the front mounting box extends into the top through hole of the front mounting box, and the extended end is fixedly connected to the top of the central rotating shaft. The outer wall of the central rotating shaft has symmetrical threaded grooves. The front mounting block is fitted into the front mounting box. The upper and lower front mounting blocks are fitted together. When the central rotating shaft is driven to rotate, the upper and lower front mounting blocks approach each other, causing the front clamping shaft on the rear end face of the upper and lower front mounting blocks to approach and clamp the component. This clamping motor is powered by a battery and is equipped with a separate switch.

[0006] As a preferred technical solution of this utility model, the rear adjustment mechanism includes a side rotating shaft, a knob, a side fixed shaft, a rear mounting block, and a drive component. The side rotating shaft is rotatably installed on the left and right sides of the rear mounting box, and the side fixed shaft is fixedly installed. The top end of the side rotating shaft extends from a through hole on the side rotating shaft and a knob is fixed at the top end. Symmetrical threaded grooves are also distributed on the side rotating shaft. The rear mounting block is placed in the rear mounting box and is installed in conjunction with the threaded grooves on the side rotating shaft. It is movably fitted with the side fixed shaft. The drive component is provided on the back of the rear mounting block. The rear clamping shaft is installed through the drive component. Under the action of the drive component, the two rear clamping shafts can be driven to rotate, thereby causing the component to move.

[0007] As a preferred technical solution of this utility model, both the front clamping shaft and the rear clamping shaft are covered with antistatic material. The driving component is a drive motor, which is installed on the rear side of the rear mounting block. The rear side of the rear mounting box has a through groove. The drive motor is powered by a battery and controlled by a remote control device. The output shaft of the drive motor extends from the through hole on the rear mounting block to the front side and is fixedly connected to the rear clamping shaft at the extended end.

[0008] The beneficial effects of this utility model are as follows: By using a stepper motor to drive the inner frame and the integrated connecting frame, the angle of the clamped circuit board can be precisely controlled to rotate or even flip 180 degrees. Operators do not need to manually move the circuit board and can quickly adjust it to the optimal working angle (such as welding bottom components or detecting specific angles), which greatly improves the convenience of operation and work efficiency. Through the rear adjustment mechanism, after the circuit board is fixed by the front clamping shaft and the rear clamping shaft, its position can still be finely adjusted, realizing non-destructive, efficient, and micron-level precision position calibration in the clamping state.

[0017] As a preferred technical solution of this utility model, the rear adjustment mechanism includes a side rotating shaft 16, a knob 17, a side fixed shaft 18, a rear mounting block 19, and a drive component. The side rotating shaft 16 is rotatably installed on the left and right sides of the rear mounting box 11, and the side fixed shaft 18 is fixedly installed.

It is movably fitted with the side fixed shaft 18. The drive component is provided on the back of the rear mounting block 19, and the rear clamping shaft 21 is installed through the drive component.

[0018] As a preferred technical solution of this utility model, the driving component is a drive motor 20. The drive motor 20 is installed on the rear side of the rear mounting block 19. The rear side of the rear mounting box 11 has a through groove. The drive motor 20 is powered by a battery and controlled by a remote control device. The output shaft of the drive motor 20 extends forward from the through hole on the rear mounting block 19 and is fixedly connected to the rear clamping shaft 21 at the extended end.

[0019] The working principle of this invention is as follows: In use, the circuit board to be operated is placed in the central area of ​​the inner frame, and the rotating motor is started. The rotating motor drives the bidirectional lead screw located in the mounting slots on the front and rear sides of the inner frame to rotate. The rotation of the bidirectional lead screw causes the symmetrical mounting blocks that are threaded into it to move synchronously and in opposite directions (one to the left, one to the right) along the mounting slots. The movement of the left and right mounting blocks causes the front mounting box and the rear mounting box fixed at their inner ends to move synchronously. By controlling the rotation direction and angle of the rotating motor, the distance between the front mounting box and the rear mounting box on both sides can be precisely adjusted to accommodate circuit boards of different widths. After the width is adjusted to the correct position, the front adjustment mechanism in the front mounting box is activated. The front clamping motor operates, driving the central shaft connected to its output shaft to rotate. The symmetrically distributed threaded grooves on the outer wall of the central shaft engage with the front mounting blocks. The rotation of the central shaft causes the upper and lower front mounting blocks to move synchronously and in opposite directions (one upwards, one downwards) along the central shaft under the action of the threads. The movement of the upper and lower front mounting blocks drives the front clamping shaft mounted at their front ends to move synchronously, thereby clamping the front edge of the circuit board from above and below. For the rear side, the operator manually rotates the knobs on the left and right sides of the rear mounting box in the rear adjustment mechanism. The knobs drive the side shaft to rotate. The symmetrical threaded grooves on the side shaft engage with the rear mounting blocks.

[0020] The rotation of the side pivot causes the upper and lower rear mounting blocks to move synchronously and in opposite directions (one upwards, one downwards) along the side pivot and the fixed side mounting shaft under the action of the threads. The movement of the upper and lower rear mounting blocks drives the rear clamping shaft mounted at their front end to move synchronously, thereby clamping the rear edge of the circuit board from the top and bottom. At this point, the circuit board is stably clamped between the front and rear clamping shafts. When it is necessary to adjust the angle of the clamped circuit board (such as flipping it over to observe the bottom or rotating it to a specific angle), first ensure that the studs have been unscrewed out of the through holes of the inner frame (if they were previously locked), and then start the stepper motor. The stepper motor's output shaft rotates and is fixedly connected to the shaft of the integrated connecting frame on the front side of the inner frame. The shaft of the integrated connecting frame on the rear side of the inner frame is movably inserted into the blind hole on the inner wall of the rear side of the outer frame. Therefore, the rotation of the stepper motor's output shaft directly drives the entire inner frame (along with the circuit board clamped inside) to rotate precisely around the axis formed by the front and rear shafts. By controlling the rotation angle and direction of the stepper motor, the circuit board can be rotated at any angle, or even flipped 180 degrees. After adjustment, if it needs to be stabilized at a horizontal angle, the studs on the left and right sides of the outer frame can be screwed into the through holes on the side of the inner frame to mechanically lock the inner frame and prevent shaking. When the circuit board is firmly clamped by the front and rear clamping shafts, if it is necessary to make a small left-right position adjustment to the circuit board (such as precisely aligning test points or pads), it is not necessary to loosen the clamps. The drive component (drive motor) on the back of the rear mounting block in the rear adjustment mechanism can be activated. The drive motor is powered by a battery and can be controlled by a remote control. The output shaft of the drive motor rotates, which drives the rear clamping shaft fixedly connected to it to rotate. Since the rear edge of the circuit board is clamped by the upper and lower rear clamping shafts (the contact surface is the circumferential surface of the rear clamping shaft), the rotation of the rear clamping shaft will drive the circuit board to produce a small linear displacement along its length direction (i.e., the left and right direction) through friction. By precisely controlling the rotation angle and direction of the drive motor, high-precision left and right position fine adjustment of the circuit board in the clamped state can be achieved.
