Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a fixed turning tool for circuit board welding. Background Art

[0002] Circuit boards are also known as circuit boards, PCB boards, aluminum substrates, high-frequency boards, ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, etc. Circuit boards are mainly composed of pads, vias, mounting holes, wires, components, connectors, fillings, electrical boundaries, etc. Usually, after the components on the circuit board are inserted, the electronic components need to be soldered to the circuit board. In order to prevent the electronic components on the circuit board from being firmly fixed, it is usually necessary to solder the front and back sides of the circuit board at the same time. For example, Chinese patent CN2018114673715 discloses a front-back flip-type fixture that is convenient for circuit board soldering. It includes a mounting plate for fixing the circuit board to be processed and a wire pressing plate. The front side of the mounting plate is provided with at least two elastic clamps for fixing the circuit board. The two ends of the mounting plate are respectively hinged to two fixed platforms so that the mounting plate can flip and swing around its hinge point. A limiting column is provided on any of the fixed platforms. One end of the wire pressing plate is hinged to one end of the top of the mounting plate so that the wire pressing plate can be clamped and closed or loosened and separated with the top of the mounting plate around the hinge point to form a fixed wire groove for clamping the wire.

[0003] The above structure mainly uses the cooperation of fixing screws and compression springs to fix the wire pressing plate when performing the fixing operation of the wire pressing plate. Therefore, each time the circuit board is replaced for soldering, the screws need to be loosened before the compression spring can be released to fix the wire pressing plate, which increases the installation and disassembly operation time and reduces work efficiency. In addition, the positioning of the above device after flipping the mounting plate is mainly supported by screws. After long-term and repeated use, the connection between the screws and the fixing platform will become loose. Therefore, when the mounting plate is flipped, the screws cannot ensure that they can support and limit the flipped mounting plate, which will cause the mounting plate to move, thereby making it impossible for the operator to perform soldering operations on the circuit board placed in the mounting plate.

The movement of the rotating hinge is connected to the upper surface of the pressure plate, so that the pressure plate can be rotated by the rotating hinge.

[0008] Specifically, a plurality of latching openings are formed on a side of the upper surface of the pressure plate close to the buckle assembly.

[0009] Further description of this solution, the snap assembly includes a mounting shell and a pressing piece, the mounting shell is arranged on the other end of the upper surface of the storage plate, a rotating shaft is provided inside the mounting shell, and the pressing piece is sleeved on the outer surface of the rotating shaft, so that the pressing piece can be rotated through the rotating shaft, and one end of the pressing piece is provided with a moving block, and one end of the moving block extends outward from the mounting shell.

[0010] Specifically, a spring member is provided between the pressing member and the mounting shell, a first hook is provided at the center of the pressing member, a second hook is provided on the inner surface of the mounting shell, one end of the spring member is hooked at the first hook, and the other end of the spring member is hooked at the second hook.

[0012] The beneficial effects of the utility model are:

[0013] 1. When fixing the circuit board before welding, this tool can first place the circuit board directly into the storage cavity, and then rotate the pressure plate to press the circuit board placed inside the storage cavity. Subsequently, the buckle assembly directly abuts the pressure plate to fix the pressure plate. After the subsequent welding is completed, it is only necessary to directly press the buckle assembly to quickly release the abutment on the pressure plate, so that the pressure plate can be quickly opened to facilitate the removal of the circuit board workpiece in the storage cavity, thereby reducing the operation time of installing and removing the pressure plate and improving work efficiency.

[0014] 2. Before the mounting plate is flipped, the tool can abut the limit block against the upper end surface of the first abutment column. Subsequently, after the mounting plate is flipped, the limit block can abut against the upper end surface of the second abutment column to ensure that the mounting plate remains stable before and after flipping. By using a column structure as a support and limiting structure for the limit block, the stability of the mounting plate after flipping can be guaranteed, and the movement of the mounting plate after flipping can be avoided, thereby ensuring that the operator can perform welding operations on the circuit board placed in the mounting plate normally.

Furthermore, the technical features described below in the various embodiments of the present invention may be combined with one another as long as they do not conflict with one another.

Subsequently, multiple material placement stations 61 are opened inside the storage cavity 6, and a pressure plate 7 movably connected is provided at one end of the upper surface of the storage cavity 6, and the bottom surface of the pressure plate 7 faces the storage cavity 6. A snap assembly 8 is provided at the other end of the upper surface of the storage plate 5, and the snapping end of the snap assembly 8 is in contact with the upper surface of the pressure plate 7. Subsequently, multiple snap-in openings 71 are opened on the side of the upper surface of the pressure plate 7 close to the snap-in assembly 8, so that the snapping end of the snap assembly 8 can be in contact with the snap-in opening 71, thereby realizing the abutment limit of the pressure plate 7.

[0027] Subsequently, a through hole 21 is provided inside the support column 2, and a boss 11 is provided on both sides of the storage plate 5. The boss 11 is rotatably provided in the through hole 21, so that the storage plate 5 can be rotated by the cooperation of the boss 11 and the through hole 21, thereby realizing the flipping operation of the storage plate 5. Then, a support platform 9 is provided at one end of the upper surface of the pressure plate 7, and a rotating hinge 10 is provided on the upper part of the support platform 9. The movement of the rotating hinge 10 is connected to the upper surface of the pressure plate 7, so that the pressure plate 7 can be rotated by the rotating hinge 10.

[0028] As attached Figure 1 、 2After the welding is completed, the clamping plate 7 can be quickly released, thereby quickly opening the clamping plate 7 and removing the clamping plate 7 from the storage cavity 6.

[0029] Moreover, before the storage plate 5 is flipped, the tool can abut the limit block 12 against the upper end surface of the first abutment column 3. Subsequently, after the storage plate 5 is flipped, the limit block 12 can abut against the upper end surface of the second abutment column 4, ensuring that the storage plate 5 can remain stable before and after flipping. By adopting a column structure as a supporting and limiting structure for the limit block 12, the stability of the storage plate 5 after flipping can be guaranteed, and the movement of the storage plate 5 after flipping can be avoided, thereby ensuring that the operator can normally perform welding operations on the circuit board placed in the storage plate 5.

[0030] It should be noted that the material placement station 61 passes through the storage plate 5 .

[0031] As attached Figure 1 、 2 As shown in Figures 5, 6, 7 and 8, the snap assembly 8 includes a mounting shell 81 and a pressing member 82.

A first hook 821 is provided at the center of the pressing member 82, and a second hook 811 is provided on the inner surface of the mounting shell 81. One end of the spring member 85 is hooked on the first hook 821, and the other end of the spring member 85 is hooked on the second hook 811.

[0034] When it is necessary to perform abutment and limit on the pressure plate 7 later: by releasing the downward pressure on the pressing member 82, the downward pressure on the pressing member 82 can be eliminated, so that the spring member 85 can be reset to lift the pressing member 82, so that the pressing member 82 can be rotated and reset through the rotating shaft 83, thereby synchronously driving the moving block 84 to perform a reset operation, so that the moving block 84 can move forward and move the moving block 84 to the locking port 71, thereby achieving abutment and limit on the pressure plate 7.
