The movable buoy is equipped with a magnetic ring, and the sliding column is equipped with a sensing element. The position difference generated by the up-and-down movement of the movable buoy and the sensing element is generated. The sensing element is generally a long strip of circuit board and a sensing element soldered on the circuit board. One end of the circuit board is connected to a power source by two conductive wires with quick-release connectors soldered on it.

Therefore, the directional terms used are for illustration and understanding of the present invention, and not for limiting the present invention.

[0021] Please refer to Figure 1-2 As shown, this utility model provides a welding clamping device 100, including a base plate frame 1 and a panel frame 2 covering the base plate frame 1.

[0022] The base plate frame 1 includes a base plate body 11, two fixing posts 12 respectively disposed at opposite ends of the base plate body 11 along a first direction, and a clamping unit 13 disposed on the base plate body 11 for fixing the circuit board.

[0023] The clamping unit 13 includes two rows of magnet units 131 spaced apart along the second direction and embedded in the base plate body 11, a clamping plate 132 fixed to the base plate body 11, and a plurality of clamping grooves 133 arranged at intervals on the side of the clamping plate 132 away from the base plate body 11.

[0024] Each row of magnet units 131 extends along the first direction, and the clamping plate 132 extends along the first direction and is spaced apart from the magnet units 131. The wire clamping groove 133 extends along the second direction. The first direction is perpendicular to the second direction. In this embodiment, the base plate frame 1 is described as a rectangular structure, where the first direction is defined as its width direction and the second direction is defined as its length direction.

[0025] Each row of magnet units 131 can be a single integral structure made of magnetic material, or it can be formed by arranging multiple small separate structures at intervals along the first direction. In this embodiment, it is preferable that each row of magnet units 131 consists of multiple magnets 1311 embedded in the base plate body 11 and arranged at intervals along the first direction. This achieves the magnetic positioning effect on the circuit board while saving the amount of magnetic material used.

[0026] The panel frame 2 includes a panel body 21, a clearance opening 22 penetrating the middle area of ​​the panel body 21, two fixing holes 23 penetrating the panel body 21 and located on opposite sides of the clearance opening 22 along the first direction, a pressure wall 24 extending along the first direction and spanning the opposite sides of the clearance opening 22, and a plurality of positioning grooves 25 formed on one of the outer peripheral sides of the panel body 21 parallel to the first direction.

[0027] When the panel body 21 is placed on the base plate body 11, the two fixing posts 12 on the base plate body 11 pass through the two fixing holes 23 on the panel body 21, forming a quick positioning of the panel body 21 and the base plate body 11. Moreover, the pressure wall 24 is located between the two rows of magnet units 131, and the outer peripheral side of the panel body 21 with the wire-fixing groove 25 is located on the side of the clamping plate 132 near the magnet unit 131, and the plurality of wire-fixing grooves 25 are respectively arranged opposite to the plurality of clamping grooves 133.

[0028] The panel body 21 has a clearance opening 22 which can be used to observe whether the circuit board is accurately clamped and aligned when the panel body 21 is covered on the base plate body 11, and is used for fine-tuning operations.

[0029] The pressure wall 24 can enhance the clamping and positioning effect on the circuit board.

[0030] In use, the entire circuit board (not shown) with multiple target circuit board units is placed manually on the base plate 11, and the wires to be soldered to each target circuit board unit are assembled into the wire clamping grooves 133 of the base plate 11. Then, the panel frame 2 is placed on the base plate frame 1, and the fixing post 12 and fixing hole 23 cooperate to achieve quick positioning, thereby forming a pressure on the circuit board. The panel frame 2 uses its own weight to press and position the circuit board. At this time, the two electrode pads of each target circuit board unit are aligned with the outer positions of the two fixed wire grooves 25 of the panel body 21. At the same time, the wires installed in each wire clamping groove 133 extend to the corresponding fixed wire groove 25 to form abutment, thus completing the preparation before soldering. Then, the entire soldering clamping device 100 is moved to the soldering machine for batch spot welding. After spot welding, the multiple target circuit board units on the entire circuit board are separated to obtain multiple target circuit boards. This not only effectively improves the soldering efficiency, but also improves the soldering reliability and consistency.

[0031] The use of the aforementioned welding clamping device replaces the manual process of aligning and connecting wires one by one before welding, greatly saving labor costs and solving the problem of uneven welding.

[0032] When the panel frame 2 presses and positions the circuit board, a flexible buffer layer 26 is attached to the side of the pressure wall 24 closest to the base plate body 11 to avoid scratching the circuit board. For example, the flexible buffer layer is an adhesive layer. This provides flexible buffer protection for the circuit board.

[0033] More preferably, to further improve welding efficiency, in this embodiment, the clamping unit 13 includes two units and is spaced apart from each other on the base plate body 11. Correspondingly, the pressure wall 24 also has two units, each corresponding to the two rows of magnet units 131 of each of the two clamping units 13.

[0034] In this embodiment, to further improve welding reliability and stability, the base plate frame 1 further includes at least two first fixing magnets 14 respectively embedded on opposite sides of the base plate body 11 along the first direction, and the panel frame 2 further includes at least two second fixing magnets 26 respectively embedded on opposite sides of the panel body 21 along the first direction. The two first fixing magnets 14 and the two second fixing magnets 26 are respectively arranged facing each other to form a magnetic attraction. This further enhances the pressing and positioning effect of the panel frame 2 on the circuit board and prevents the circuit board from shifting.

[0035] Compared with the prior art, the welding clamping device of this utility model is provided with a base plate frame and a panel frame covering the base plate frame; a fixing post and a clamping unit for clamping the circuit board are provided on the base plate body of the base plate. The clamping unit includes two rows of magnet units spaced apart on the base plate body, a clamping plate fixed to the base plate body, and a plurality of wire clamping grooves formed on the surface of the clamping plate. The two rows of magnet units and the clamping plate extend parallel to each other along a second direction and are spaced apart along a first direction. A clearance opening is opened in the middle area of ​​the panel body of the panel frame, and two fixing holes are provided that penetrate the panel body and are distributed on opposite sides of the clearance opening along the first direction. A pressure wall is provided that extends along the first direction and spans across the opposite sides of the clearance opening, and a plurality of wire clamping grooves are opened on one of the outer peripheral sides of the panel body parallel to the first direction. The entire circuit board with multiple target circuit board units is placed on the base plate body. The circuit board is magnetically fixed by two rows of magnet units, and then the panel body is placed on the base plate body, so that the two fixing posts pass through the two fixing holes to form quick positioning. The pressure wall is located between the two rows of magnet units, thereby pressing the circuit board. The panel body presses the circuit board with its own weight to prevent the circuit board from shifting. The outer periphery of the panel body with the fixed wire groove is located on the side of the clamping plate near the magnet unit, and multiple fixed wire grooves are respectively arranged to face multiple clamping wire grooves. The two solder pads of each target circuit board unit in the circuit board are located outside the two fixed wire groove positions respectively. Only manual installation of the wire to be welded is required to install the wire in each clamping wire groove and extend it to the corresponding fixed wire groove. Then, the welding clamping device is placed on the welding machine for batch spot welding, realizing partial automated assembly. It not only has good welding consistency and reliability, but also effectively improves production efficiency and reduces production costs.
