[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-6 The utility model provides an embodiment: a PCB board welding fixing clamp for preventing damage, comprising a base plate 1 and two sets of brackets 2, the two sets of brackets 2 are fixedly mounted on the left and right ends of the base plate 1,
[0025] A fixed frame 3 is rotatably installed between the upper ends of the two groups of brackets 2, and two groups of limit plates 4 are rotatably installed on the upper and lower sides of the left end of the fixed frame 3. A slide groove 5 is symmetrically opened in the front and back of the fixed frame 3, and a first spring 6 is installed in each of the two groups of slide grooves 5. Sliders 7 are slidably installed in each of the two groups of slide grooves 5. A splint 8 is fixedly installed between the two groups of sliders 7. A guide rod 9 is installed in the right end of each of the two groups of slide grooves 5. Two groups of grooves 10 are opened on the left and right sides of the fixed frame 3. Two groups of protrusions 11 are fixedly installed on one symmetrical side of the upper ends of the two groups of brackets 2. The two groups of grooves 1 0 is movably inserted in the two groups of protrusions 11, a driving assembly is provided in the base plate 1 and the two groups of brackets 2, and a limiting assembly is provided on the fixed frame 3. This device clamps the PCB board between the four groups of limiting plates 4, and slides the two groups of sliders 7 and the clamping plate 8 to the left under the action of the elastic force of the two groups of guide rods 9 to clamp and fix the PCB board. The fixing frame 3 is flipped by the driving assembly to facilitate soldering of the components inserted on the PCB board. During the flip, the components inserted on the PCB board are fixed by the limiting assembly to prevent them from detaching during the flipping process.
[0026] Furthermore, the four groups of protrusions 11 and the inner walls of the four groups of grooves 10 are all semicircular, and the four groups of protrusions 11 are all made of rubber material. The four groups of protrusions 11 are adapted to the inner walls of the four groups of grooves 10. This structure is based on the shapes of the four groups of grooves 10 and the four groups of protrusions 11, so that the four groups of grooves 10 can be squeezed open when the fixed frame 3 is flipped, and the four groups of protrusions 11 are inserted into the four groups of grooves 10 to limit and fix the fixed frame 3.
[0027] Furthermore, the driving assembly includes a rotating shaft 12, which is rotatably installed in the base plate 1, and a first synchronous wheel 13 is fixedly installed on both ends of the rotating shaft 12. A second synchronous wheel 14 is rotatably installed in the upper ends of the two groups of rotating shafts 12. Two groups of synchronous belts 15 are sleeved on the two groups of first synchronous wheels 13 and the two groups of second synchronous wheels 14. The two groups of second synchronous wheels 14 are fixedly connected to the fixed frame 3. This structure drives the two groups of first synchronous wheels 13, the two groups of second synchronous wheels 14 and the two groups of synchronous belts 15 to rotate through the rotating shaft 12, which can drive the fixed frame 3 to rotate on the upper ends of the two groups of brackets 2, so as to facilitate the flip welding of the PCB board fixed in the fixed frame 3.
[0028] Furthermore, the limiting assembly includes a pressure plate 16, which is arranged on the upper side of the fixed frame 3, and two groups of movable rods 17 are rotatably installed on the lower sides of the left and right ends of the pressure plate 16. The two groups of movable rods 17 at the right end of the pressure plate 16 are movably inserted in the right end of the fixed frame 3, and the lower ends of the two groups of movable rods 17 at the left and right ends of the pressure plate 16 are sleeved with a second spring 18. Two groups of card slots 19 are opened on the left side of the fixed frame 3, and the two groups of movable rods 17 at the left end of the pressure plate 16 are movably inserted in the two groups of card slots 19. After the components are inserted into the PCB board, this structure rotates the pressure plate 16 on the two groups of movable rods 17 inserted at the right end of the fixed frame 3 to fit the components on the PCB board, and the two groups of movable rods 17 at the left end of the pressure plate 16 are stuck in the two groups of card slots 19, so that the components can be fixed when the PCB board is flipped, thereby improving the tightness of the PCB board for welding components.
[0029] Furthermore, the lower surface of the base plate 1 is wrapped with an anti-slip layer, and the anti-slip layer on the lower side of the base plate 1 is made of rubber material. This structure prevents the base plate 1 from sliding when placed on the table, thereby increasing the friction between the base plate 1 and the table.
[0030] Furthermore, the height of the two groups of brackets 2 is greater than half of the front and rear width of the fixed frame 3, and the centers of the left and right sides of the fixed frame 3 are inserted into the upper ends of the two groups of brackets 2. This structure, based on the height of the brackets 2 and the size of half of the front and rear width of the fixed frame 3, ensures that when the fixed frame 3 is flipped between the two groups of brackets 2, the front and rear ends of the fixed frame 3 will not collide with the bottom plate 1, and there is space for the fixed frame 3 to flip.
[0031] Furthermore, the inner walls of the two groups of slots 19 are both U-shaped, and the right end inner walls of the two groups of slots 19 are adapted to the two groups of movable rods 17. This structure facilitates the insertion of the two groups of movable rods 17 into the two groups of slots 19 according to the shape of the inner walls of the two groups of slots 19.
[0032] Furthermore, the left end of the splint 8 is concave, and the left side of the splint 8 is wrapped with latex material. This structure, based on the shape of the left side of the splint 8, facilitates the upper and lower sides of the edge of the PCB board to be limited and fixed when the splint 8 is fitted with the PCB board.
[0033] Working principle: When soldering components on PCB, Figure 2 、 Figure 3 、 Figure 6 As shown, first insert the left end of the PCB into the fixed frame 3, and rotate the upper and lower sides of the fitted PCB through the four sets of limit plates 4. Then, the clamping plate 8 and the two sets of sliders 7 slide to the left under the elastic force of the two sets of guide rods 9, so that the clamping plate 8 fits the right end of the PCB. The PCB can be fixed in the fixed frame 3, and then the component pins are inserted into the PCB. Some components need preliminary soldering, such as Figure 2 and Figure 5As shown, the pressing plate 16 is rotated on the two groups of movable rods 17 inserted at the right end of the fixed frame 3. After the pressing plate 16 is rotated, it fits with the components inserted on the PCB board, and the two groups of movable rods 17 at the left end of the pressing plate 16 are clamped in the two groups of card slots 19. According to the size of the components inserted on the PCB board, the pressing plate 16 and the four groups of movable rods 17 are tightly fixed to the PCB board under the action of the restorative force of the four groups of second springs 18, and the rotating shaft 12 is rotated. The rotation of the rotating shaft 12 drives the four groups of first synchronous wheels 13 and the four groups of second synchronous wheels 14 and the two groups of synchronous belts 15 to rotate, which can drive the fixed frame 3 to rotate on the upper ends of the two groups of brackets 2. After the fixed frame 3 rotates, the four groups of protrusions 11 at the upper ends of the two groups of brackets 2 are inserted into the four groups of grooves 10 on the left and right sides of the fixed frame 3, so that the fixed frame 3 can be fixed, and then the pins of the components inserted on the PCB board are welded. The above is the entire working principle of the present utility model.
[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
