Description

Technical Field

[0001] The utility model relates to the technical field of battery protection board processing, and particularly relates to a battery protection board welding device. Background Art

[0002] A battery protection board is mainly an integrated circuit board that protects rechargeable batteries. It is mainly designed for lithium batteries and is used to protect the batteries from overcharging, over-discharging, over-current, short-circuit, and over-high-temperature charging and discharging damage. Due to the material characteristics of lithium batteries, they cannot be overcharged, over-discharged, short-circuited, or exposed to too high temperatures, otherwise it will cause battery damage and even pose a safety risk. Therefore, lithium battery components usually come with a protection board with a sampling resistor and a current fuse to ensure the safe use of the batteries. During the processing of the battery protection board, a large number of wires need to be soldered to the battery protection board by tin soldering.

[0003] In the prior art, during the welding process of the battery protection board, accidental contact with the battery protection board easily causes the solder joint position to shift, and the melted solder wire is likely to splash onto the components of the battery protection board, increasing the product rejection rate and thus raising the production cost. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a battery protection board welding device.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A battery protection board welding device includes a base. A receiving groove for placing the battery protection board is provided on the upper surface of the base. A cover plate for closing the receiving groove is hinged to the side wall of the base. A plurality of positioning holes are penetrated through the cover plate. A sliding groove is provided on the inner bottom wall of the receiving groove. A fixing component for fixing the battery protection board is installed on the base. The fixing component includes a moving rod that penetrates through and is slidably connected to the side wall of the base, a slider that is rotatably connected to the end of the moving rod and is slidably connected to the inner wall of the sliding groove, a fixing plate that is fixed to the upper surface of the slider and is slidably connected to the inner wall of the receiving groove, a star-shaped handle that is fixed to the end of the moving rod away from the slider, and a spring sleeved on the moving rod. One end of the spring is fixed to the side wall of the slider, and the other end of the spring is fixed to the inner wall of the sliding groove.

[0006] By adopting the above technical solution, when it is necessary to weld the battery protection board, the staff opens the cover plate and pulls the star handle outwards, so that the slider and the fixed plate move to one side. Then, the battery protection board is placed in the receiving groove and the star handle is released. The slider drives the fixed plate to move under the elastic force of the spring and presses against the side wall of the battery protection board, thereby fixing the battery protection board in the receiving groove, reducing the probability of the battery protection board shifting during the welding process. Subsequently, the cover plate is closed so that the solder joints to be welded are exposed through the positioning holes and other components are covered, reducing the probability of the melted solder splashing onto other components, thereby reducing the product scrap rate.

[0007] Further, an external thread is provided at one end of the moving rod close to the slider, and a threaded groove threadedly connected to the external thread is provided on the side wall of the base.

[0008] By adopting the above technical solution, when it is necessary to take and place the battery protection board, the staff pulls the star handle outwards and rotates the moving rod to thread the external thread on the moving rod with the threaded groove on the base, so that the moving rod is fixed on the base, thereby fixing the position of the fixed plate, eliminating the cumbersome operation of the staff always pulling the star handle outwards with one hand, and facilitating the quick taking and placing of the battery protection board.

[0009] Further, a rubber sheet is fixed on the side wall of the fixed plate.

[0010] By adopting the above technical solution, the rubber sheet is made of rubber material, and its material is elastic, reducing the vibration generated when the fixed plate presses against the battery protection board under the elastic force of the spring, thereby reducing the wear caused by the fixed plate to the battery protection board.

[0011] Further, a plurality of silica gel strips are fixed on the inner bottom wall of the receiving groove.

[0012] By adopting the above technical solution, the silica gel strips are made of silica gel material, and their material has a large friction force and is elastic, reducing the wear between the battery protection board and the inner bottom wall of the receiving groove, further reducing the probability of the battery protection board moving in the receiving groove, enhancing the stability of the battery protection board. In addition, the silica gel strips make the bottom part of the battery protection board suspended, facilitating the staff to take out the battery protection board from the receiving groove.

[0013] Further, a plurality of flared grooves are provided at the intersection between the inner wall of the receiving groove and the upper surface of the base.

[0014] By adopting the above technical solution, the setting of the flared grooves is conducive to the staff putting their fingers into the flared grooves and lifting the battery protection board upwards, facilitating the taking out of the battery protection board in the receiving groove.

[0015] Further, an upper magnetic block is embedded at the bottom of the cover plate, and a lower magnetic block magnetically attracted to the upper magnetic block is embedded on the upper surface of the base.

[0016] By adopting the above technical solution, the upper magnetic block and the lower magnetic block are magnetically attracted to each other, so that the cover plate is adsorbed and fixed on the base, thereby enhancing the stability of the cover plate and reducing the probability of the cover plate shaking during welding.

[0017] Furthermore, a U-shaped rod is fixed on a side of the upper surface of the cover plate away from the hinge axis.

[0018] By adopting the above technical solution, the setting of the U-shaped rod provides a fulcrum for the cover plate, making it convenient for the staff to pull and open the cover plate through the U-shaped rod.

[0019] Furthermore, a plurality of anti-slip pads are fixed to the bottom of the base.

[0020] By adopting the above technical solution, the anti-slip pad is made of rubber material, and its surface has a large friction coefficient, which increases the friction force at the bottom of the base, reduces the probability of displacement of the base, and enhances the stability of the base.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the battery protection board needs to be welded, the staff opens the cover plate and pulls the star-shaped handle outward, so that the slider and the fixed plate move to one side, and then the battery protection board is placed in the receiving slot and the star-shaped handle is released. The slider drives the fixed plate to move and press against the side wall of the battery protection board under the elastic force of the spring, thereby fixing the battery protection board in the receiving slot, reducing the probability of the battery protection board position shifting during welding. Then, the cover plate is closed to expose the solder joints to be welded through the positioning port and cover other components, reducing the probability of the solder wire splashing onto other components after melting, thereby reducing the product scrap rate;

[0023] 2. In this application, when the battery protection board needs to be taken out, the staff pulls the star-shaped handle outward and rotates the moving rod, so that the external thread on the moving rod is threadedly connected with the thread groove on the base, so that the moving rod is fixed on the base, thereby fixing the position of the fixed plate, eliminating the tedious operation of the staff to pull the star-shaped handle outward with one hand all the time, and facilitating the quick removal and placement of the battery protection board;

[0024] 3. In the present application, the rubber sheet is made of rubber material, which is elastic and reduces the vibration caused by the fixing plate pressing against the battery protection plate under the action of the spring force, thereby reducing the wear of the fixing plate on the battery protection plate.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] As Figures 1-3 shown, an embodiment of the present application discloses a battery protection board welding device, including a base 1, a cover plate 2, and a fixing component 3.

[0031] The base 1 is a cuboid structure. An accommodating groove 11 for placing the battery protection board is opened on the upper surface of the base 1, and a slide groove 12 is opened on the inner bottom wall of the accommodating groove 11. The cover plate 2 is a rectangular plate structure, and the cover plate 2 is hinged on the side wall of the base 1 for closing the accommodating groove 11. A plurality of positioning ports 21 are penetrated through the cover plate 2.

[0032] The fixing component 3 is installed on the base 1 for fixing the battery protection board. The fixing component 3 includes a moving rod 31, a slide block 32, a fixed plate 33, a star-shaped handle 34, and a spring 35. The moving rod 31 is a horizontally arranged round rod structure. The moving rod 31 penetrates through the side wall of the base 1 and is slidably connected. The slide block 32 is a cuboid structure. The slide block 32 is slidably connected to the inner wall of the slide groove 12, and the slide block 32 is rotatably connected to the end of the moving rod 31. The fixed plate 33 is a rectangular plate structure. The fixed plate 33 is fixed on the upper surface of the slide block 32, and the fixed plate 33 is slidably connected to the inner wall of the accommodating groove 11. The star-shaped handle 34 is fixed to the end of the moving rod 31 away from the slide block 32, and the axis of the star-shaped handle 34 coincides with the axis of the moving rod 31. The spring 35 is sleeved on the moving rod 31. One end of the spring 35 is fixed to the side wall of the slide block 32, and the other end of the spring 35 is fixed to the inner wall of the slide groove 12.

[0033] When it is necessary to weld the battery protection board, the staff member opens the cover plate 2 and pulls the star-shaped handle 34 outwards, causing the slider 32 and the fixed plate 33 to move to one side. Then, the battery protection board is placed in the receiving groove 11 and the star-shaped handle 34 is released. The slider 32 drives the fixed plate 33 to move under the elastic force of the spring 35 and presses against the side wall of the battery protection board, thereby fixing the battery protection board in the receiving groove 11, reducing the probability of the battery protection board shifting during the welding process. Subsequently, the cover plate 2 is closed so that the solder joints to be welded are exposed through the positioning openings 21 and other components are covered, reducing the probability of the melted solder splashing onto other components, thereby reducing the product rejection rate.

[0034] To facilitate the quick loading and unloading of the battery protection board, an external thread 4 is provided at one end of the moving rod 31 close to the slider 32, and a threaded groove 13 that is threadedly connected to the external thread 4 is provided on the side wall of the base 1. When it is necessary to load and unload the battery protection board, the staff member pulls the star-shaped handle 34 outwards and rotates the moving rod 31, so that the external thread 4 on the moving rod 31 is threadedly connected to the threaded groove 13 on the base 1, causing the moving rod 31 to be fixed on the base 1, thereby fixing the position of the fixed plate 33, eliminating the cumbersome operation of the staff member always pulling the star-shaped handle 34 outwards with one hand, and thus facilitating the quick loading and unloading of the battery protection board.

[0035] To reduce the wear caused by the fixed plate 33 to the battery protection board, a rubber sheet 5 is fixed on the side wall of the fixed plate 33. The rubber sheet 5 is made of rubber material, and its material is elastic, reducing the vibration generated when the fixed plate 33 presses against the battery protection board under the elastic force of the spring 35, thereby reducing the wear caused by the fixed plate 33 to the battery protection board.

[0036] To enhance the stability of the battery protection board, a plurality of silica gel strips 6 are fixed on the inner bottom wall of the receiving groove 11. The silica gel strips 6 are made of silica gel material, and their material has a large friction force and is elastic, reducing the wear between the battery protection board and the inner bottom wall of the receiving groove 11, further reducing the probability of the battery protection board moving in the receiving groove 11, thereby enhancing the stability of the battery protection board. In addition, the silica gel strips 6 make the bottom part of the battery protection board suspended, facilitating the staff member to take out the battery protection board from the receiving groove 11.

[0037] To facilitate the removal of the battery protection board in the receiving groove 11, a plurality of flared grooves 14 are provided at the intersection of the inner wall of the receiving groove 11 and the upper surface of the base 1. The setting of the flared grooves 14 is conducive to the staff member putting their fingers into the flared grooves 14 and lifting the battery protection board upwards, thereby facilitating the removal of the battery protection board in the receiving groove 11.

[0038] In order to reduce the probability of the cover plate 2 shaking during welding, an upper magnetic block 7 is embedded in the bottom of the cover plate 2, and a lower magnetic block 8 magnetically attracted to the upper magnetic block 7 is embedded in the upper surface of the base 1. The upper magnetic block 7 and the lower magnetic block 8 are magnetically attracted to each other, thereby adsorbing and fixing the cover plate 2 on the base 1, enhancing the stability of the cover plate 2, thereby reducing the probability of the cover plate 2 shaking during welding.

[0039] In order to facilitate opening of the cover plate 2, a U-shaped rod 9 is fixed to the side of the upper surface of the cover plate 2 away from the hinge axis. The setting of the U-shaped rod 9 provides a fulcrum for the cover plate 2, thereby facilitating the staff to pull the cover plate 2 open through the U-shaped rod 9.

[0040] In order to enhance the stability of the base 1, a plurality of anti-skid pads 10 are fixed to the bottom of the base 1. The anti-skid pads 10 are made of rubber material and have a large friction coefficient on their surface, which increases the friction force at the bottom of the base 1 and reduces the probability of displacement of the base 1, thereby enhancing the stability of the base 1.

[0041] The battery protection board welding device in this embodiment is used in the following way: when the battery protection board needs to be welded, the staff opens the cover plate 2 and pulls the star-shaped handle 34 outward, so that the slider 32 and the fixing plate 33 move to one side, and then releases the star-shaped handle 34 after placing the battery protection board in the receiving groove 11. The slider 32 drives the fixing plate 33 to move and press against the side wall of the battery protection board under the elastic force of the spring 35, thereby fixing the battery protection board in the receiving groove 11, reducing the probability of the battery protection board position shifting during welding, and then closing the cover plate 2 so that the welding point to be welded is exposed through the positioning port 21 and covers other components, reducing the probability of the solder wire splashing onto other components after melting, thereby reducing the product scrap rate.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
