[0020] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0021] First Embodiment

[0022] Reference Figure 1-3 This invention proposes an embodiment of a circuit board positioning and assembly fixture, comprising a placement template 1, with placement grooves 2 for placing circuit boards at both ends of the upper surface of the placement template 1, a second horizontal bar 8 fixedly connected to the rear side of the upper surface of the placement template 1, and receiving frames 10 adapted to the placement template 1 rotatably connected to the top ends of the second horizontal bar 8 via hinges 9, the receiving frames 10 having receiving openings 13, and a positioning template 14 detachably disposed inside the receiving openings 13.

[0023] The surface of the positioning template 14 is provided with a number of positioning slots 15. When the receiving frame 10 covers the upper surface of the template 1, the multiple positioning slots 15 are located at the corresponding positions of the electrical components that need to be positioned and installed on the circuit board.

[0024] In this embodiment, after the circuit board is placed inside the placement slot 2, the receiving frame 10 is closed. After the multiple positioning slots 15 cover the corresponding positions on the circuit board where electrical components need to be positioned and installed, the operator can place the corresponding electrical components on the surface of the circuit board, and the subsequent connection equipment will fix the electrical components on the surface of the circuit board for use.

[0025] Electrical components can be rectifier bridges, temperature sensors, current transformers, etc. The connection equipment can fix the electrical components by screwing, or by pre-applying solder paste to the circuit board, placing the electrical components on the surface of the circuit board, and then reflow soldering them in the reflow oven to complete the connection and fixation of the electrical components using surface mount technology.

[0026] The positioning template 14 is detached and installed inside the receiving port 13, which facilitates the removal of the positioning template 14 and the replacement of different positioning slots 15 for assembly work, thus benefiting the production and processing of circuit boards.

[0027] Second Embodiment

[0028] Please refer to Figure 1 and Figure 2 Based on the same concept as the first embodiment described above, a first horizontal bar 3 is fixedly connected to the front side of the upper surface of the template 1, and a hollow block 4 is fixedly connected to the middle of the top of the first horizontal bar 3. A double-bead V-shaped spring sheet 5 is provided inside the hollow block 4. The two clips on the double-bead V-shaped spring sheet 5 extend movably to the outside of the hollow block 4. An opening 11 adapted to the hollow block 4 is opened on the surface of the receiving frame 10, and a card interface 12 adapted to the double-bead V-shaped spring sheet 5 is opened on the inner wall of the opening 11.

[0029] In this embodiment, after the receiving frame 10 covers the upper surface of the placement template 1, the opening 11 is fitted onto the surface of the hollow block 4. After the elastic force of the double-bead V-shaped spring sheet 5 pushes the two card heads into the interior of the card interface 12, the receiving frame 10 and the placement template 1 can be locked and limited, thereby improving the stability during the positioning process.

[0030] Third Embodiment

[0031] Please refer to Figure 4 Based on the same concept as the first embodiment described above, grooves 6 are provided on the front and rear sides of the upper surface of the placement template 1. A through-hole 7 for connecting and fixing with the moving platform is provided through the bottom of the inner wall of the groove 6. Both ends of the rear side of the positioning template 14 are fixedly connected with bayonets 18. Both ends of the rear side of the inner wall of the receiving opening 13 are provided with slots 19 that are adapted to the bayonets 18. Both ends of the front side of the positioning template 14 are fixedly connected with locking blocks 16. Both ends of the front side of the inner wall of the receiving opening 13 are provided with locking grooves 17 that are adapted to the locking blocks 16.

[0032] In this embodiment, after the locking block 16 is embedded inside the locking groove 17, the positioning template 14 is pushed into the receiving port 13, which in turn drives the locking slot 18 into the slot 19 to form an interference fit, thereby fixing the positioning template 14 inside the receiving port 13 for use. The disassembly and assembly operation is simple and convenient, and it is easy to quickly replace the positioning template 14.

[0033] Furthermore, the inner wall edges of the placement slot 2 and the inner wall edges of the multiple positioning slots 15 are all rounded to avoid scratching the surface of the circuit board.

[0034] During operation, after placing the circuit board inside the placement slot 2, the receiving frame 10 is closed. Multiple positioning slots 15 cover the corresponding positions on the circuit board where electrical components need to be positioned and installed. The operator can then place the corresponding electrical components onto the surface of the circuit board. Subsequent connection equipment will then fix the electrical components onto the surface of the circuit board for use. The positioning template 14 is detached and placed inside the receiving opening 13, making it easy to remove the positioning template 14 and replace different positioning slots 15 for assembly. During assembly, after the locking block 16 is inserted into the locking groove 17, the positioning template 14 is pushed into the receiving opening 13, which in turn causes the locking slot 18 to be inserted into the locking groove 19 to form an interference fit, thereby fixing the positioning template 14 inside the receiving opening 13 for use.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
