Description

Technical Field

[0001] This utility model belongs to the field of protection board processing technology, and in particular relates to a solder clamping device for lithium battery protection boards. Background Technology

[0002] The lithium battery protection board provides overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, and battery status monitoring for lithium batteries during operation. It consists of a circuit board and matching electronic components. The electronic components are usually soldered onto the circuit board. In actual soldering, in order to improve the stability of the circuit board and improve soldering efficiency, a clamping device is usually used to clamp the circuit board to keep it in a relatively fixed position.

[0003] A search revealed that CN220534164U, published on February 27, 2024, discloses a convenient clamping lithium battery protection board production device, relating to the field of lithium battery protection board production technology. This convenient clamping lithium battery protection board production device includes a base. Its features include: a bracket fixedly connected to the outer wall of the base's bottom end; a clamping block slidably connected to the inner wall of the base; a groove formed on the outer wall of the base; a connecting rod hinged to the outer wall of the clamping block; a slider hinged to the outer wall of the connecting rod; a guide rod slidably connected to the inner wall of the slider; and a pull rod fixedly connected to the outer wall of the clamping block. This invention, by configuring a clamping block, connecting rod, slider, and guide rod, allows the clamping block to be pushed, and the connecting rod to drive the slider to slide along the outer wall of the guide rod, simultaneously moving the clamping block on the other side, thus clamping and fixing the protection board. This achieves the effect of clamping and fixing protection boards of different sizes, improving the production efficiency of protection boards.

[0004] Existing technology uses a lever to engage the wedge and slot to clamp or release the protection board by linking the two clamping blocks. However, in actual use, due to the distance between adjacent slots, existing technology can only clamp circuit boards of specific sizes within a certain size range, which is inconvenient. Furthermore, the fumes generated during soldering cause environmental pollution. Therefore, we provide a lithium battery protection board soldering clamping device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a soldering clamping device for lithium battery protection boards. The clamping mechanism can clamp circuit boards of any size within a certain size range, and the purification mechanism filters and purifies the fumes. This solves the problems of existing technology, which can only clamp circuit boards of specific sizes within a certain size range, which is inconvenient to use, and the environmental pollution caused by the fumes generated during soldering.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a soldering clamping device for a lithium battery protection board, comprising a protection board body, a clamping mechanism on the outside of the protection board body, clamping mechanisms including clamping plates symmetrically arranged at the left and right ends of the protection board body, a mounting plate at the bottom of the protection board body, telescopic rods symmetrically fixed at the front and rear ends of the lower wall of the mounting plate, and U-shaped guide rails symmetrically fixed at the front and rear ends of the upper wall of the mounting plate, with a left connecting plate and a right connecting plate respectively on the left and right sides of the guide rails; and a purification mechanism, comprising a box fixed at the lower end of the telescopic rods, a fan fixed at the rear wall of the box, and a mounting box rotatably connected to the right wall of the box via a hinge, wherein a dust filter plate and an activated carbon filter plate are respectively arranged inside the mounting box, with the dust filter plate located on the side closer to the box.

[0008] The present invention is further configured such that the left connecting plate is slidably connected to the guide rail, the right connecting plate is fixedly connected to the guide rail, and a rectangular groove is provided on the side wall of the guide rail, and a bolt that is threadedly connected to the left connecting plate is provided inside the rectangular groove.

[0009] The present invention is further configured such that the left connecting plate and the right connecting plate are provided with a protrusion fixed to the clamping plate at one end away from each other, and a baffle is fixed at the end of the protrusion away from the clamping plate.

[0010] The present invention is further provided with protruding strips along the left and right sides of the lower wall of the protective plate body for fixing to the clamping plate.

[0011] The present invention is further configured such that a mounting tube with a U-shaped cross-section is fixedly provided on the rear wall of the box, and an L-shaped telescopic plate is provided in the internal gap of the mounting tube. An LED light is fixed at the corner of the telescopic plate, and a bolt is threadedly connected to the rear wall of the mounting tube, with the front end of the bolt abutting against the telescopic plate.

[0012] The present invention is further configured such that a flexible hose is fixedly provided at the rear end of the fan, the end of the flexible hose away from the fan is fixedly provided on the front side of the upper wall of the telescopic plate, and an air collection hood is fixedly provided at the end of the flexible hose away from the fan.

[0013] The present invention is further configured such that a ventilation groove is provided on the right wall of the mounting box, and a rectangular plate is fixed on the right wall of the mounting box, and three bolts are provided on the rectangular plate for threaded connection with the box body.

[0014] The present invention is further configured such that end plates are symmetrically fixed at the lower ends of the left and right side walls of the box body, and screws are threaded to both the front and rear sides of the end plates. A bottom plate is fixed at the lower end of the screws, and an anti-slip pad is fixed on the lower wall of the bottom plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a clamping mechanism, allows the clamping plates to move upward by moving the mounting plate upward. During the upward movement of the clamping plates, under the action of gravity, the lower ends of the clamping plates move closer to each other, while the upper ends of the clamping plates move further apart, until the distance between the inner sides of the upper ends of the two clamping plates is greater than the size of the protective plate body. The protective plate body is then placed on the two protruding strips, and the upward force on the mounting plate is released. Under the action of gravity, the lower ends of the clamping plates slide on the upper wall of the box and move away, until the combined action of the two clamping plates clamps and fixes the protective plate body. Moreover, since the distance between the left connecting plate and the right connecting plate is adjustable, the distance between the two clamping plates is also adjustable. Therefore, by adjusting the distance between the left connecting plate and the right connecting plate, a protective plate body of any size within a certain range can be clamped.

[0017] 2. This utility model, by setting up a purification mechanism, uses a fan to generate negative pressure, causing smoke and dust to enter the interior of the chamber, then pass through a dust filter plate and an activated carbon filter plate. The dust filter plate intercepts the dust particles, while the activated carbon filter plate purifies the smoke and dust, preventing the smoke and dust from drifting into the external environment and causing environmental pollution.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides a solder clamping device for a lithium battery protection board, including a protection board body 1. A clamping mechanism 2 is provided on the outside of the protection board body 1. The clamping mechanism 2 includes clamping plates 201 symmetrically arranged at the left and right ends of the protection board body 1 for clamping the protection board body 1. A mounting plate 205 is provided below the protection board body 1. The angle of the clamping plates 201 can be adjusted by moving the mounting plate 205 up and down, thereby achieving clamping and releasing of the protection board body 1. The front and rear ends of the lower wall of the mounting plate 205 are symmetrically fixed. A telescopic rod 205a is provided, which allows the mounting plate 205 to move up and down in its original position. The front and rear ends of the upper wall of the mounting plate 205 are symmetrically fixed with U-shaped guide rails 203, which allows the left connecting plate 204 to move only in the left and right directions. The left and right sides of the guide rail 203 are respectively provided with a left connecting plate 204 and a right connecting plate 202. By adjusting the relative position of the left connecting plate 204 and the right connecting plate 202, the distance between the two clamping plates 201 can be adjusted, so that the two clamping plates 201 can clamp the protective plate body 1 of the corresponding size.

[0030] Specifically, the left connecting plate 204 is slidably connected to the guide rail 203, so that the distance between the left connecting plate 204 and the right connecting plate 202 can be adjusted when the left connecting plate 204 moves. The right connecting plate 202 is fixedly connected to the guide rail 203. The side wall of the guide rail 203 is provided with a rectangular groove 203a to provide moving space for the bolt 204a. The rectangular groove 203a is provided with a bolt 204a that is threadedly connected to the left connecting plate 204. After the distance between the two clamping plates 201 is adjusted, the left connecting plate 204 and the right connecting plate 202 can only be fixed relative to each other by tightening the bolt 204a, so as to avoid relative movement between the two clamping plates 201 during use and thus affect the normal clamping of the protective plate body 1.

[0031] The left connecting plate 204 and the right connecting plate 202 are fitted with a gap at one end away from each other and are fixed to the clamping plate 201. The protrusion 206 is located on the upper side of the clamping plate 201, so that the weight of the lower side of the clamping plate 201 is greater than the weight of the upper side of the clamping plate 201, so that the lower end of the clamping plate 201 can slide along the upper wall of the box 301 when the mounting plate 205 moves up and down. A baffle 206a is fixed at the end of the protrusion 206 away from the clamping plate 201. The area of ​​the baffle 206a is larger than the area of ​​the protrusion 206 to prevent the left connecting plate 204 and the right connecting plate 202 from detaching from the protrusion 206.

[0032] The lower wall of the protective plate body 1 has protruding strips 201a along the left and right sides for fixing to the clamping plate 201, providing a platform for placing the protective plate body 1.

[0033] The operation process of this embodiment is as follows: When in use, firstly, the distance between the upper ends of the two clamping plates 201 is roughly adjusted. According to the required size of the protective plate body 1, the mounting plate 205 is moved upward slightly. Then, the bolt 204a is loosened, and the left connecting plate 204 is moved to the left until the distance between the two clamping plates 201 allows the protective plate body 1 to be placed on the two protrusions 201a. At this time, the protective plate body 1 is placed on the two protrusions 201a, the bolt 204a is tightened, and the upward force on the mounting plate 205 is released. Under the action of gravity, the two clamping plates 201 move downward until the lower ends of the two clamping plates 201 are in contact with the upper wall of the box 301. At this time, the left and right side walls of the protective plate body 1 are simultaneously in contact with the side walls of the protective plate body 1, thereby achieving the clamping of the protective plate body 1.

[0034] Example 2

[0035] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: the purification mechanism 3 includes a housing 301 fixed to the lower end of the telescopic rod 205a. The interior of the housing 301 is hollow. A fan 309 is fixed to the rear wall of the housing 301. The air inlet end of the fan 309 is fixed to the housing 301, and the interior of the air inlet end of the fan 309 communicates with the interior of the housing 301. A mounting box 305 is rotatably connected to the right wall of the housing 301 via a hinge 305a, for mounting the dust filter plate 310 and the activated carbon filter plate 3. 06 provides installation space. The interior of the installation box 305 is equipped with a dust filter plate 310 and an activated carbon filter plate 306. At the location of the dust filter plate 310, a through groove smaller than the size of the dust filter plate 310 is opened on the right wall of the box 301. This through groove allows airflow to enter the installation box 305. The dust filter plate 310 can filter dust particles in the smoke, while the activated carbon in the activated carbon filter plate 306 can adsorb odors. The dust filter plate 310 is located on the side closer to the box 301, so that the smoke first passes through the dust filter plate 310 and then through the activated carbon filter plate 306.

[0036] Specifically, the rear wall of the housing 301 is fixed with an installation tube 303 with a U-shaped cross-section, so that the telescopic plate 302 can only move up and down in its original position to adjust the height of the air inlet end of the hose 304. The internal gap of the installation tube 303 is fitted with an L-shaped telescopic plate 302 to provide a fixed platform for the end of the hose 304 away from the fan 309. An LED light 302a is fixed at the corner of the telescopic plate 302, which can provide illumination during welding. The rear wall of the installation tube 303 is threaded with a bolt 303a. The front end of the bolt 303a abuts against the telescopic plate 302. After loosening the bolt 303a, the telescopic plate 302 moves up and down accordingly, so that the height of the end of the hose 304 away from the fan 309 can be adjusted.

[0037] A flexible hose 304 is fixedly installed at the rear end of the fan 309. The interior of the flexible hose 304 is connected to the interior of the collection hood. At the same time, the interior of the flexible hose 304 is also connected to the interior of the air outlet of the fan 309. The end of the flexible hose 304 away from the fan 309 is fixedly installed on the front side of the upper wall of the telescopic plate 302. An air collection hood 304a is fixedly installed at the end of the flexible hose 304 away from the fan 309 to expand the air collection area.

[0038] The right wall of the mounting box 305 is provided with a ventilation groove 305b, which allows the filtered and purified air to be discharged from the box 301. The size of the ventilation groove 305b is smaller than the size of the dust filter plate 310. A rectangular plate 308 is fixed on the right wall of the mounting box 305. The rectangular plate 308 is provided with bolts 308a that are threaded to the box 301. The rectangular plate 308 is fixed to the box 301 by bolts 308a, so that the mounting box 305 is in a fixed state.

[0039] End plates 301a are symmetrically fixed to the lower ends of the left and right side walls of the housing 301. Screws 307a are threaded to both the front and rear sides of the end plates 301a. A base plate 307 is fixed to the lower end of the screws 307a. Anti-slip pads 307b are fixed to the lower wall of the base plate 307 to improve the anti-slip ability of the lithium battery protection board soldering clamp device on the placement platform during use. With the above settings, by operating the base plate 307 to rotate, the corresponding screws 307a will rotate until the anti-slip pads 307b on the lower walls of the four base plates 307 are in contact with the placement platform, so that the lithium battery protection board soldering clamp device can be stably placed on the placement platform.

[0040] Furthermore, both the LED lamp 302a and the fan 309 are electrically connected to an external power source via conductive wires, and both the LED lamp 302a and the fan 309 are existing technologies, so their models are not limited here.

[0041] The operation process of this embodiment is as follows: When in use, loosen the bolt 303a, then operate the telescopic plate 302 to move up and down to adjust the height of the gas collection hood 304a. After the adjustment is completed, tighten the bolt 303a.

[0042] When in use, the blower 309 operates, creating a negative pressure inside the hose 304. This negative pressure causes the fumes generated during welding to pass through the gas collection hood 304a and the hose 304 in sequence into the interior of the housing 301. The fumes then pass through the dust filter plate 310 and the activated carbon filter plate 306 in sequence, and are discharged from the housing 301 after being filtered by dust and purified by fumes.
