Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, specifically to a positioning fixture for circuit board processing. Background Technology

[0002] Circuit boards are the "skeleton" of electronic devices, undertaking the core functions of fixing components and transmitting signals. They need to go through four core stages: design, board manufacturing, assembly, and testing. Each stage directly affects the reliability, stability, and lifespan of the final product. In order to prevent the circuit board from moving or vibrating due to external forces and to ensure process accuracy and operational safety during the soldering, testing, assembly, or debugging of circuit boards, it is necessary to clamp and position the circuit board. For example, the utility model patent with publication number CN217751120U discloses an adjustable positioning fixture for circuit board processing. By setting a base, a placement seat, a fixing plate, a plug rod, a tension spring, a groove, a threaded rotating rod, a throttle, a limit rod, a movable block, and a clamping plate, it realizes the function of adjusting the placement angle of the circuit board. Although it is convenient for positioning and adjusting the circuit board, when performing batch positioning tests on multiple circuit boards, it is necessary to rotate and adjust multiple threaded rotating rods in sequence, which takes a long time for batch positioning of multiple circuit boards, resulting in low efficiency for batch positioning of multiple circuit boards.

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.

[0014] Please see Figures 1 to 4A positioning fixture for circuit board processing includes a positioning frame 1, a positioning plate 2, a limiting plate 3, a clamping frame 4, supporting rubber pads 5, and clamping rubber plates 6. The positioning plate 2 is rotatably mounted on the upper side of the positioning frame 1. Two limiting plates 3 are provided, and the two limiting plates 3 are symmetrically connected to the top of the positioning plate 2. Multiple clamping frames 4 are provided, and multiple clamping frames 4 are detachably mounted in an array between two limiting plates 3. Each clamping frame 4 has a clamping groove to facilitate stable placement of the circuit board. Multiple supporting rubber pads 5 are provided, and multiple supporting rubber pads 5 are connected in a rectangular array in each clamping groove. Multiple clamping rubber plates 6 are provided, and multiple clamping rubber plates 6 are detachably connected to the upper side of multiple supporting rubber pads 5, and the clamping rubber plates 6 are lifted and installed on the upper side of the supporting rubber pads 5.

[0015] refer to Figure 1 , Figure 3 as well as Figure 4 An adjustment assembly is installed between multiple clamping rubber plates 6. The adjustment assembly includes a fixed frame 7, an electric push rod 8, a lifting plate 9, a lifting frame 10, an adjustment frame 11, an adjustment plate 12, an adjustment bar 13, and an adjustment rod 14. The fixed frame 7 is fixedly connected to the top of the positioning plate 2. The electric push rod 8 is installed on the fixed frame 7. The lifting plate 9 is fixedly connected to the output end of the electric push rod 8. There are two lifting frames 10, which are symmetrically connected to the top of the lifting plate 9. The adjustment frame 11 is fixedly connected between the two lifting frames 10. A stabilizing plate 21 is fixedly connected to each of the two lifting frames 10. The fixed frame 7 has a stabilizing groove for the two stabilizing plates 21 to slide, which increases the number of lifting frames 10. The smoothness of sliding on the fixed frame 7 increases the stability of the two lifting frames 10 driving the adjustment frame 11 to rise and fall. Multiple adjustment plates 12 are set, and multiple adjustment plates 12 are connected in an equidistant array within the adjustment frame 11. Two adjustment bars 13 are set, and two adjustment bars 13 are fixedly connected to each adjustment plate 12. Adjustment grooves for installing adjustment bars 13 are provided on the adjustment frame 11. Multiple adjustment rods 14 are set, and multiple adjustment rods 14 are fixedly connected between each adjustment plate 12 and multiple adjacent clamping rubber plates 6. Two locking posts 20 are staggered on both sides of each adjustment plate 12, and two locking grooves matching the locking posts 20 are staggered on both sides of each adjustment plate 12. When multiple clamping plates 6 need to be installed according to the number of circuit boards and clamping frames 4, multiple adjusting plates 12 are installed sequentially at equal intervals in the adjusting frame 11, so that multiple adjusting bars 13 are all moved into the adjusting slots, and multiple locking posts 20 are moved into multiple locking slots respectively. This increases the stability of the multiple adjusting plates 12 installed in the adjusting frame 11, so that multiple adjusting rods 14, multiple clamping plates 6 and multiple supporting pads 5 can stably clamp and fix multiple circuit boards, increasing the stability of circuit board processing and testing.

[0016] refer to Figure 1A rotating assembly is provided between the positioning frame 1 and the positioning plate 2. The rotating assembly includes a motor 15, a rotating frame 16 and a rotating column 17. The motor 15 is mounted on the positioning frame 1 via a mounting plate. The rotating frame 16 is fixedly connected between the output end of the motor 15 and the positioning plate 2. The rotating column 17 is fixedly connected to the other side of the rotating frame 16. The positioning frame 1 is provided with a rotating groove for the rotating column 17 to rotate. When the rotating frame 16 rotates, the rotating column 17 can also rotate in the rotating groove, which increases the stability of the rotating frame 16 driving the positioning plate 2 to rotate. When the motor 15 is started, it drives the rotating frame 16 to rotate, which in turn drives the positioning plate 2 to rotate. This allows the two limit plates 3 and multiple clamping frames 4 to rotate multiple circuit boards, thereby allowing the processing and testing angles of multiple circuit boards to be adjusted.

[0017] refer to Figure 1 as well as Figure 2 Multiple limiting posts 18 are detachably connected between the two limiting plates 3. Multiple limiting ports matching the limiting posts 18 are equally spaced on the limiting plates 3. Two limiting strips 19 are symmetrically connected on the clamping frame 4. Two limiting grooves matching the limiting strips 19 are symmetrically opened on the limiting posts 18. When multiple clamping frames 4 need to be installed according to the number of circuit boards, multiple clamping frames 4 are installed sequentially and equidistantly between two limiting plates 3, and multiple limiting posts 18 are inserted into multiple limiting ports respectively, so that multiple limiting strips 19 enter multiple limiting grooves respectively. Multiple clamping frames 4 can be stably installed between two limiting plates 3, and multiple clamping frames 4 can be quickly disassembled at the same time.

[0018] In summary, firstly, multiple clamping frames 4 are sequentially installed between two limiting plates 3 according to the number of circuit boards, and multiple limiting posts 18 clamp and fix the multiple clamping frames 4. At the same time, multiple adjusting plates 12 are sequentially installed at equal intervals in the adjusting frame 11, so that multiple clamping rubber plates 6 correspond to multiple supporting rubber pads 5 in sequence. After multiple circuit boards are sequentially installed in multiple clamping frames 4, the electric push rod 8 is activated, so that the lifting plate 9 and the two lifting frames 10 drive the adjusting frame 11 to rise and fall, and the multiple adjusting plates 12 and the multiple adjusting rods 14 drive the multiple clamping rubber plates 6 to rise and fall, so that the multiple clamping rubber plates 6 and the multiple supporting rubber pads 5 clamp and fix the multiple circuit boards in sequence, thereby improving the batch positioning efficiency of multiple circuit boards.
