Technical Field

[0001] The utility model relates to an auxiliary clamp for PCB board welding, belonging to the technical field of PCB board clamps. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts.

[0003] The existing auxiliary clamp for PCB board welding on the market uses springs at both ends of the support rod to push the No. 1 rubber block to move toward the No. 4 rubber block, and can clamp the PCB board, which is beneficial to welding. However, the auxiliary clamp for welding can only fix the clamped PCB board in parallel. The parallel fixed PCB board requires workers to hold the soldering gun vertically to the top of the PCB board for welding. Therefore, long-term vertical operation of the arm will make the arm numb, which is not conducive to long-term use. Therefore, an auxiliary clamp for PCB board welding is urgently needed to solve the above problems. Utility Model Content

The utility model has a reasonable structure and good practicality. The upward movement of the threaded ring through the rotation of the screw can make the connecting plate drive the support rod to swing so that the angle can be adjusted, thereby relieving the manual arm during welding.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an auxiliary fixture for PCB board welding, including a support plate, a movable plate, a groove, a slider, a No. 1 rubber block, a telescopic rod, a No. 2 rubber block, a No. 3 rubber block, a No. 4 rubber block, a support rod, a connecting plate, a threaded ring, a bearing 1, a screw, a bearing 2, a rotating head, a spring, a fixed block and a rotating ring, a group of movable plates are provided on the top of the support plate, and a rotating ring is connected to the inner side of the group of movable plates by sliding, a support rod is inserted into the interior of the rotating ring, the left and right ends of the support rod are penetrated by fixed blocks, and the two ends of the support rod are sleeved with springs, the front end welding of the No. 1 rubber block and the No. 4 rubber block A fixed block is connected, and the rear ends of the No. 2 rubber block and the No. 3 rubber block are welded with a fixed block. A telescopic rod is provided on one side of the No. 1 rubber block and the No. 2 rubber, and a telescopic rod is also provided on one side of the No. 2 rubber block and the No. 4 rubber block. A screw is inserted into the top of the front end moving plate of the support plate, and bearings 1 and 2 are provided at the upper and lower ends of the screw. A threaded ring is sleeved on the outside of the screw, and a rotating head is provided on the top of the screw. One side of the threaded ring is connected to the bottom of the connecting plate, and the top of the connecting plate is connected to the surface of the support rod. A groove is provided on the inner side of the moving plate at the front end of the moving plate, and a group of sliders are provided at the bottom of a group of moving plates at the top of the support plate.

[0006] Furthermore, a group of slide grooves are provided on the top of the support plate, and the interior of the group of slide grooves is connected to the sliding block.

A screw 804 is inserted into the top of the moving plate 2 at the front end of the support plate 1, and bearings 1 803 and 2 805 are provided at the upper and lower ends of the screw 804. A threaded ring 802 is sleeved on the outside of the screw 804, and a rotating head 806 is provided on the top of the screw 804. One side of the threaded ring 802 is connected to the bottom of the connecting plate 801, and the top of the connecting plate 801 is connected to the surface of the support rod 8. A groove 201 is provided on the inner side of the moving plate 2 at the front end of the moving plate 2, and a group of sliders 202 are provided at the bottom of a group of moving plates 2 at the top of the support plate 1.

[0020] As the first embodiment of the utility model: a group of sliding grooves are opened on the top of the support plate 1, and the interior of the group of sliding grooves is connected to the slider 202. This design facilitates the movable plate 2 to move toward each other, which is beneficial to the docking of the No. 1 rubber block 3 and the No. 4 rubber block 7 with the No. 2 rubber block 5 and the No. 3 rubber block 6. The bottom of the connecting plate 801 is connected to one side of the thread ring 802 by sliding, and the top of the connecting plate 801 is also connected to the surface position of the support rod 8 by sliding. The upward movement of the thread ring 802 of this design facilitates the connection plate 801 to swing, and can also make the support rod 8 swing. The screw 804 is placed inside the groove 201, and the internal width of the groove 201 is larger than the diameter of the outer ring of the thread ring 802. This design is beneficial for the thread ring 802 to move up and down inside the groove 201. Bearing 1 803 and bearing 2 805 are embedded in the inside of the groove. This design is beneficial to the rotation of the screw 804.

At this time, the No. 1 rubber block 3 is pulled to the left. Since the fixing block 10 provided on the No. 1 rubber block 3 is inserted outside the support rod 8, the No. 1 rubber block 3 can be separated from the No. 4 rubber block 7. Now, it is only necessary to place the PCB board inside the No. 3 rubber block 6 and the No. 4 rubber block 7. The spring 9 sleeved on the left end of the support plate 1 can push the fixing block 10 to move, so that the No. 1 rubber block 3 and the No. 4 rubber block 7 can be docked. At this time, the screw 804 inserted by the front end moving plate 2 of the support plate 1 will rotate the rotating head 806 When the screw rod 804 is rotated, the threaded ring 802 outside the screw rod 804 will move toward the top of the screw rod 804. Since the bottom of the connecting plate 801 is connected to one side of the threaded ring 802 by sliding, and the top of the connecting plate 801 is also connected to the surface of the support rod 8 by sliding, when the threaded ring 802 moves, the connecting plate 801 can make the support rod 8 swing under the action of the rotating circle 11, so that the first rubber block 3, the second rubber block 5, the third rubber block 6 and the fourth rubber block 7 can be adjusted to a certain swing angle. This design allows the threaded ring 802 to move upward through the rotation of the screw rod 804, so that the connecting plate 801 can drive the support rod 8 to swing so that the angle can be adjusted, thereby relieving the manual arm during welding.
