Technical Field

[0001] The utility model relates to the technical field of PCBA board cleaning, in particular to a PCBA board cleaning fixture. Background Art

[0002] PCBA board refers to the assembled printed circuit board. Printed circuit board (PCB) is a carrier used to support and connect electronic components, while PCBA connects these electronic components to the printed circuit board through welding and other technologies to form a complete circuit system. Therefore, PCBA board is an indispensable part of electronic products. PCBA board cleaning is an important part of the electronic manufacturing process, the purpose is to remove impurities such as dirt, flux, solder residue, etc. on the board to ensure the performance and reliability of the circuit board.

[0003] After searching, the utility model patent with Chinese patent publication number CN218502913U discloses a PCBA board cleaning fixture, which belongs to the technical field of PCBA board cleaning. When cleaning the PCBA board, it is necessary to clamp the PCBA boards one by one, which is time-consuming and labor-intensive, and the clamping efficiency is low, which affects the cleaning efficiency of the PCBA board. The utility model comprises a support frame, and two symmetrically distributed connecting plates are fixed on the top of the support frame. The top of the two connecting plates is commonly fixed with a top plate, and a threaded rod is threadedly connected to the center position of the top side of the top plate, and a pressing plate is rotatably connected to the bottom end of the threaded rod; the utility model screws down the threaded rod, and the connecting plate limits and guides the movement of the pressing plate, so that the threaded rod drives the pressing plate to move downward, and the pressing plate clamps and fixes multiple PCBA boards synchronously, and can fix multiple PCBA boards at one time. Compared with the traditional PCBA board cleaning device, several buckle structures are omitted, and multiple cumbersome manual buckle fixing operations are no longer required, which saves a lot of time and effectively improves the cleaning efficiency of the PCBA board.

[0004] After searching the above patent, it was found that the device has processed the joint fixation of multiple PCBA boards, but it failed to process the flipping and cleaning of the PCBA boards. After cleaning one side of the PCBA board, when the other side of the PCBA board needs to be cleaned, the operator needs to take out the PCBA board and re-fix it, which makes the operation more cumbersome.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A PCBA board cleaning fixture comprises a base 1, wherein two slide grooves 2 are arranged at the upper end of the base 1, wherein a vertical plate 1 3 and a vertical plate 2 5 are slidably connected inside the two slide grooves 2, wherein the side wall of the vertical plate 1 3 is rotatably connected to a circular plate 1 4, wherein the side wall of the vertical plate 2 5 is rotatably connected to a circular plate 2 6, wherein the side walls of the circular plate 1 4 and the circular plate 2 6 are both fixedly connected to a stop block 13; a top block 16, wherein the top block 16 is arranged inside the base 1, wherein the side walls of the vertical plate 1 3 and the vertical plate 2 5 are both fixedly connected to a fixed block 15, wherein the end of the top block 16 is fitted with the side wall of the fixed block 15, wherein a rod column 17 is fixedly connected through the inside of the top block 16, wherein the rod column 17 is rotatably connected to the base 1, wherein the side wall of the fixed block 15 is arranged in an arc shape, wherein the two ends of the top block 16 are respectively fitted with the side walls of the two fixed blocks 15 by rotating the rod column 17, so that the two The fixed blocks 15 push the vertical plate 1 3 and the vertical plate 2 5 to slide respectively, and then the operator places the PCBA board between the two blocks 13. The block 13 is set to be concave, and the inner wall of the block 13 is installed with a rubber protective pad. The rod column 17 is rotated again to make the end of the top block 16 disengage from the fixed block 15, so that the vertical plate 1 3 and the vertical plate 2 5 drive the blocks 13 set on their respective side walls to slide, and the PCBA board is clamped and fixed from both ends. Then the operator cleans its surface. When it is necessary to clean the other side of the PCBA board, the block 13 set on the side wall is driven by the circular plate 2 6 to rotate, and the other side of the PCBA board is turned upward, so that the operator can clean it conveniently. At the same time, the other block 13 drives the circular plate 1 4 to rotate.

[0023] A slot 7 is provided inside the circular plate 6, and a movable block 8 is slidably connected inside the slot 7. A spring 9 is fixedly connected between the side wall of the movable block 8 and the inner wall of the slot 7. The movable block 8 sliding inside the slot 7 is restored to its original position through the elasticity of the spring 9. Both the movable block 8 and the slot 7 are set to be square.

[0024] The side wall of the vertical plate 5 is rotatably connected with a rod body 10, the rod body 10 and the side wall of the circular plate 6 are slidably connected, and the end of the rod body 10 is fixedly connected to the side wall of the movable block 8. By manually rotating the rod body 10, the movable block 8 drives the circular plate 6 to rotate.

[0025] A plurality of limit grooves 11 are arranged in a circular array on the side wall of the vertical plate 25, and the limit blocks 12 are symmetrically fixedly connected to the side wall of the rod body 10. The limit blocks 12 are slidably connected to the limit grooves 11. The rod body 10 is limited by the cooperation between the limit grooves 11 and the limit blocks 12 to prevent the circular plate 26 from rotating when the PCBA board is cleaned. When the circular plate 26 needs to be rotated, the rod body 10 is pulled to make the limit blocks 12 slide out of the limit grooves 11, and then the rod body 10 is rotated.

[0026] Two springs 2 14 are fixedly connected inside the two slide grooves 2, wherein the ends of two springs 2 14 are fixedly connected to the side walls of the vertical plate 1 3, and the ends of the other two springs 2 14 are fixedly connected to the side walls of the vertical plate 2 5. When the top block 16 is separated from the fixed block 15, the elasticity of the springs 2 14 allows the vertical plate 1 3 and the vertical plate 2 5 to slide relative to each other inside the two slide grooves 2.

[0027] The upper end of the rod column 17 is fixedly connected with a plate 18 , and a protrusion is provided on the upper end of the plate 18 . The rod column 17 is rotated by manually rotating the plate 18 .

[0028] In the utility model, the operator manually rotates the plate 18 to make the rod column 17 drive the top block 16 to rotate, so that the two ends of the top block 16 are respectively fitted with the side walls of the two fixed blocks 15, and the two fixed blocks 15 respectively push the vertical plate 1 3 and the vertical plate 2 5 to slide, so that the two abutments 13 are opened, and then the operator places the PCBA board to be cleaned between the two abutments 13, and rotates the rod column 17 again to make the end of the top block 16 disengage from the fixed block 15, and through the elasticity of the spring 2 14, the vertical plate 1 3 and the vertical plate 2 5 slide relatively inside the two slide grooves 2, and the PCBA board is clamped and fixed from both ends by the two abutments 13, and then the operator cleans its surface.

[0029] When the other side of the PCBA board needs to be cleaned, the rod body 10 is pulled to make the limit block 12 slide out of the limit groove 11, and then the rod body 10 is rotated to make the movable block 8 drive the circular plate 2 6 to rotate, and the other side of the PCBA board is turned upward, and the rod body 10 is released. Through the elasticity of the spring 1 9, the movable block 8 drives the rod body 10 to slide automatically, so that the limit block 12 slides to the corresponding limit groove 11, thereby limiting the rod body 10.
