Description

Technical Field

[0001] The utility model relates to the technical field of battery protection board processing, in particular to a tin adding device for a battery protection board. Background Art

[0002] A battery protection board is mainly an integrated circuit board that plays a protective role for rechargeable batteries. The reason why the battery needs protection is determined by its own characteristics. Since the materials of lithium batteries themselves determine that they cannot be overcharged, over-discharged, over-current, short-circuited, or charged and discharged at ultra-high temperatures, the lithium battery components will always be accompanied by a protection board with a sampling resistor and a current fuse. The battery protection board is one of the important components commonly used in batteries. During the processing process, it is necessary to pre-process solder paste on its surface pads.

[0003] In the Chinese utility model patent with the publication number CN221185025U, a solder pre-adding device for a lithium battery protection board is disclosed, including a frame. The frame internally is provided with a limiting mechanism. The limiting mechanism includes a cylinder, a soldering iron, a movable plate, and a card cover. A cylinder is installed on the top of the frame, and the power output end of the cylinder is installed with a soldering iron. The soldering iron is peripherally provided with a movable plate, and the bottom of the movable plate is detachably connected with a card cover for restricting the diffusion range of the solder paste.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: Tin needs to be added to multiple positions on the surface of the battery protection board. When adding tin to different positions on the battery protection board in the above patent, it is necessary for the staff to manually move the battery protection board, which is cumbersome and labor-consuming. It not only affects the accuracy of the tin adding position but also reduces the tin adding efficiency of the battery protection board. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides a tin adding device for a battery protection board.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A tin adding device for a battery protection board includes a base. Two symmetrically arranged fixing plates are fixed on the upper surface of the base. A first linear motor is commonly fixed at the upper ends of the two fixing plates. Electric push rods are fixed at the bottoms of the mover seats of the first linear motor. A tin adding mechanism for adding tin to the battery protection board is installed at the end of the output shaft of the electric push rod. Two symmetrically arranged second linear motors are fixed on the upper surface of the base. A controller electrically connected to the first linear motor, the electric push rod, the tin adding mechanism, and the second linear motor is arranged on the side wall of the base. An installation seat is arranged on the mover seat of each second linear motor. An installation groove for installing the battery protection board is opened on the upper surface of each installation seat. A positioning component for positioning the tin adding position is installed on each installation seat.

[0007] By adopting the above technical solution, when it is necessary to solder the battery protection board, the staff installs the battery protection board in the installation groove, locates the soldering position of the battery protection board through the positioning component, and then controls the first linear motor, the electric push rod and the second linear motor through the controller to adjust the position of the soldering mechanism on the surface of the battery protection board, so that the soldering mechanism solders different positions on the surface of the battery protection board, eliminating the cumbersome operation of manually moving the battery protection board by the staff, improving the accuracy of the soldering position, and at the same time improving the soldering efficiency of the battery protection board.

[0008] Further, each group of the positioning components includes a plurality of insertion rods fixed to the upper surface of the mounting seat and a positioning plate sleeved on the plurality of insertion rods and slidably connected thereto. A plurality of positioning holes are formed through the upper surface of the positioning plate.

[0009] By adopting the above technical solution, after the battery protection board is installed in the installation groove, the staff aligns the positioning plate with the plurality of insertion rods and inserts it, so that the bottom of the positioning plate abuts against the upper surface of the mounting seat, and the soldering position on the battery protection board is exposed through the positioning holes, improving the accuracy of soldering the battery protection board.

[0010] Further, a limiting groove is formed in the inner wall of the installation groove, a limiting block is slidably connected to the inner wall of the limiting groove, and a pressing block slidably connected to the inner wall of the installation groove is fixed to the side wall of the limiting block.

[0011] By adopting the above technical solution, after the battery protection board is placed in the installation groove, the staff pushes the pressing block, so that the pressing block moves towards the battery protection board and abuts against it, thereby limiting the battery protection board and reducing the probability of displacement of the battery protection board during the soldering process, enhancing the stability of the battery protection board.

[0012] Further, a plurality of cushion blocks are fixed to the inner bottom wall of the installation groove.

[0013] By adopting the above technical solution, the plurality of cushion blocks make the bottom part of the battery protection board suspended, facilitating the staff to take out the battery protection board from the installation groove.

[0014] Further, a hemispherical block is fixed to the upper end of each insertion rod, and the diameter of the hemispherical block is equal to the diameter of the insertion rod.

[0015] By adopting the above technical solution, the setting of the hemispherical block reduces the diameter of the upper end of the insertion rod, thereby reducing the difficulty of aligning the positioning plate with the insertion rod, and is conducive to aligning and inserting the positioning plate with the insertion rod.

[0016] Further, a rubber pad is fixed to the bottom of the positioning plate.

[0017] By adopting the above technical solution, the rubber pad is made of rubber material, which is elastic and reduces the wear between the positioning plate and the mounting seat as well as the battery protection plate.

[0018] Furthermore, two symmetrically arranged L-shaped plates are fixed on the upper surface of the positioning plate.

[0019] By adopting the above technical solution, the L-shaped plate provides a fulcrum for the positioning plate, making it convenient for the staff to lift the positioning plate through the L-shaped plate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, when it is necessary to tin the battery protection plate, the staff installs the battery protection plate in the installation slot, and locates the tinning position of the battery protection plate through the positioning assembly, and then controls the first linear motor, the electric push rod and the second linear motor through the controller to adjust the position of the tinning mechanism on the surface of the battery protection plate, so that the tinning mechanism tins different positions on the surface of the battery protection plate, eliminating the tedious operation of the staff to manually move the battery protection plate, improving the accuracy of the tinning position, and at the same time improving the efficiency of tinning the battery protection plate;

[0022] 2. In this application, after the battery protection board is installed in the installation slot, the staff aligns the positioning board with the multiple plug-in rods and inserts them, so that the bottom of the positioning board abuts against the upper surface of the mounting seat, and the tinning position on the battery protection board is exposed through the positioning hole, thereby improving the accuracy of tinning the battery protection board;

[0023] 3. In this application, after the battery protection board is placed in the installation slot, the staff pushes the tightening block to move the tightening block to one side of the battery protection board and tighten it, thereby limiting the battery protection board, reducing the probability of displacement of the battery protection board during the tinning process, and enhancing the stability of the battery protection board.
