[0034] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0035] An embodiment of the present invention provides a circuit board welding fixture, which solves the technical problem that the circuit board welding fixture in the prior art is inconvenient to disassemble and assemble the circuit board.

[0036] The circuit board welding fixture provided by the technical solution embodiment of the present invention, as Figures 1 - 3 shown, includes a base 10, a first hinge seat 20, a pressing plate 30, a second hinge seat 40 and a locking frame 50. The base 10 is provided with an installation groove 11 for placing the circuit board; the first hinge seat 20 is fixed to the base 10 and is located on one side of the installation groove 11; the pressing plate 30 is hinged to the first hinge seat 20 and can press the circuit board by rotating around the first hinge seat 20. The pressing plate 30 is provided with a welding interface 31; the second hinge seat 40 is fixed to the base 10 and is located on the other side of the installation groove 11; the locking frame 50 is hinged to the second hinge seat 40, and the locking frame 50 can connect with the pressing plate 30 when rotating in the direction towards the pressing plate 30 to press the circuit board, restricting the rotation of the pressing plate 30.

[0037] Specifically, the circuit board welding fixture is provided with a base 10, a first hinge seat 20, a pressing plate 30, a second hinge seat 40 and a locking frame 50. The base 10 is provided with an installation groove 11, and the circuit board to be welded can be placed in the installation groove 11 for installation. The first hinge seat 20 and the second hinge seat 40 are both fixed to the base 10 and are respectively located on both sides of the installation groove 11. The pressing plate 30 is hinged to the first hinge seat 20. After the circuit board is placed, the pressing plate 30 presses the circuit board by rotating towards the circuit board direction to achieve the stability of the circuit board. The locking frame 50 is hinged to the second hinge seat 40. After the circuit board is pressed tightly by the pressing plate 30, the locking frame 50 rotates in the direction towards the pressing plate 30 to connect with the pressing plate 30 and lock the pressing plate 30, thereby restricting the rotation of the pressing plate 30. After the pressing plate 30 is locked, the circuit board can be welded through the welding interface 31 of the pressing plate 30. With the above structure of the welding fixture, only by disconnecting the locking frame 50 from the pressing plate 30 to unlock the pressing plate 30, the installation and disassembly of the circuit board can be carried out, thus providing convenience for the installation and disassembly of the circuit board.

[0038] It can be understood that the base 10 can be any seat body structure that can be installed on the frame of the welding equipment.

[0039] In one of the embodiments, as Figures 1 - 2As shown, first handles 12 are provided on both sides of the base 10, and the first handles 12 are hinged to the base 10 and can be rotated to keep level with the base 10. Specifically, the first handles 12 can be easily held, which facilitates the transportation of the welding jig. Since the first handles 12 can be rotated to keep level with the base 10, it can facilitate the installation of the base 10 on the welding frame.

[0040] In one embodiment, in order to facilitate the installation of the base 10, the base 10 is further provided with a positioning hole 13, and the positioning hole 13 is used for inserting a positioning column to position the base 10. Specifically, when installing the base 10, the positioning hole 13 can cooperate with the positioning column on the welding frame to facilitate the positioning and installation of the base 10.

[0041] In one embodiment, Figures 1 - 2 As shown, locking grooves 14 are further provided on both sides of the base 10, and the welding jig further includes a locking plate 60, which is used to be rotatably connected to the frame and is used to enter or disengage from the locking groove 14 by rotation. Specifically, the locking plate 60 is mounted on the base 10 and is rotatably connected to the base 10. Through the arrangement of the locking groove 14 and the locking plate 60, after the installation of the base 10 is completed, the locking plate 60 only needs to be rotated to make the locking plate 60 enter the locking groove 14, and the base 10 can be locked by the locking plate 60, which provides convenience for the installation and fixation of the base 10. When the base 10 is disassembled, the locking plate 60 only needs to be rotated to make the locking plate 60 disengage from the locking groove 14.

[0042] It is understandable that the pressing plate 30 can be locked by providing a locking hole on the pressing plate 30 and the locking frame 50 is inserted into the locking hole by rotation.

[0043] In one embodiment, Figures 1 - 2 As shown, the welding port 31 is provided with a plurality of pressing frames 311 , and the pressing plate 30 can press the circuit board through the pressing frames 311 .

[0044] In one embodiment, Figure 1 As shown, a second handle 33 is provided at one end of the pressing plate 30 away from the first hinge seat 20, and the second handle 33 is fixedly connected to the pressing plate 30. Specifically, the first handle 12 can be used for holding, which provides convenience for manipulating the rotation of the pressing plate 30.

[0045] In one embodiment, Figure 1 and 3As shown, a limiting hook 51 is provided at one end of the lock frame 50 away from the base 10. The limiting hook 51 can abut against the surface of the pressing plate 30 by the rotation of the lock frame 50 in the direction towards the pressing plate 30. Specifically, after the pressing plate 30 presses the circuit board, the lock frame 50 slides in the direction towards the circuit board, so that the limiting hook 51 abuts against the upper surface of the pressing plate 30, thereby restricting the rotation of the pressing plate 30 and finally realizing the locking of the pressing plate 30. When unlocking, only by rotating the lock frame 50 can the limiting hook 51 be disengaged from the abutment with the pressing plate 30.

[0046] In one embodiment, as Figure 1 and 3 shown, the second hinge seat 40 is provided with a first locking rod 41. The first locking rod 41 is slidably connected to the second hinge seat 40 in a direction towards or away from the lock frame 50. The lock frame 50 is provided with a first locking hole 52. The first locking rod 41 can be inserted into the first locking hole 52 by sliding in the direction towards the lock frame 50, restricting the rotation of the lock frame 50 connecting the pressing plate 30. Specifically, through the arrangement of the first locking rod 41, after the lock frame 50 locks the pressing plate 30 with the lock hook, the first locking rod 41 can be slid in the direction towards the lock frame 50, so that the first locking rod 41 enters the first locking hole 52, and the lock frame 50 can be locked to prevent the lock frame 50 from disengaging from the pressing plate 30.

[0047] In one embodiment, as Figure 2 shown, the pressing plate 30 is provided with a locking block 32. The locking block 32 is provided with a second locking hole 321. The base 10 is provided with a sliding frame 15. The sliding frame 15 is located on one side of the locking block 32. The welding jig further includes a second locking rod 70. The second locking rod 70 is slidably connected to the sliding frame 15 in a direction towards or away from the locking block 32. The second locking rod 70 can be inserted into the second locking hole 321 by sliding in the direction towards the locking block 32, restricting the rotation of the pressing plate 30 pressing the circuit board. Specifically, through the arrangement of the above structure, after the pressing plate 30 presses the circuit board, the second locking rod 70 can be slid in the direction towards the locking block 32, so that the second locking rod 70 is inserted into the second locking hole 321, and the pressing plate 30 can be further locked, cooperating with the locking of the lock frame 50 to enhance the locking force of the pressing plate 30.

[0048] In one embodiment, as Figure 2As shown, the locking block 32 is further provided with a third locking hole 322, which is located below the second locking hole 321. The second locking rod 70 can also be inserted into the third locking hole 322 by sliding in the direction of the locking block 32 to restrict the rotation of the pressing plate 30 in the open state. Specifically, through the setting of the third locking hole 322, when disassembling and assembling the circuit board, it is necessary to open the pressing plate 30. After the pressing plate 30 is opened by a certain angle, the third locking hole 322 is located on one side of the second locking rod 70. At this time, the second locking rod 70 can be slid in the direction of the third locking hole 322 to insert the second locking rod 70 into the third locking hole 322, and the pressing plate 30 in the open state can be locked, providing convenience for the disassembly and assembly of the circuit board.

[0049] In one of the embodiments, as Figure 2 shown, the base 10 is further provided with a sliding seat 16, which is located on one side of the second locking rod 70. The soldering jig further includes a slider 80, which is slidably connected to the sliding seat 16 and fixedly connected to the second locking rod 70. Specifically, through the cooperation of the sliding seat 16 and the slider 80, it is convenient to control the second locking rod 70, and thus convenient for the disassembly and assembly of the circuit board.

[0050] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
