Description

Technical Field

[0001] This utility model relates to the field of battery protection board technology, and in particular to a battery protection board positioning device. Background Technology

[0002] A battery protection board is a device that monitors battery voltage and protects the battery from exceeding safety thresholds due to overcharging or over-discharging, or can cut off the circuit in time when the battery is short-circuited. The battery protection board needs to be positioned during processing, so a positioning device is required.

[0003] For example, Chinese patent document CN220903231 U discloses a positioning device for processing battery protection boards, relating to the field of processing equipment technology. It includes a worktable, with a fixed block fixedly connected to the top of the worktable. A bidirectional threaded rod is rotatably connected to the right side of the fixed block. A threaded block is threadedly connected to the outer wall of the bidirectional threaded rod. A long plate is fixedly connected to the top of the threaded block. A U-shaped box is rotatably connected to the left side of the long plate. An L-shaped slide rod is slidably connected through the top of the U-shaped box. A limit block is fixedly connected to the left surface of the L-shaped slide rod, and a cylinder is slidably connected to the outer wall of the limit block. This invention uses the rotation of the bidirectional threaded rod to cause multiple sets of threaded blocks to slide towards the center via an internal slider, thereby causing the L-shaped slide rod to retract inward. This, in turn, causes the U-shaped box and clamping plate to retract inward, thus adjusting the distance of the clamping plate. This allows the clamping plate to hold battery protection boards of different lengths and widths, thereby improving work efficiency.

[0004] The existing technology has the following problems:

[0005] When positioning and fixing the battery protection board, the existing technology cannot guarantee that the clamping position is located in the middle of the battery protection board, which may cause the battery protection board to shake during subsequent processing, reducing the practicality of the device. At the same time, the existing technology does not limit the flipping device after flipping the positioned battery protection board, which also reduces the practicality of the device. Utility Model Content

[0006] This utility model provides a battery protection board positioning device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A battery protection board positioning device includes a base, with pads fixedly connected to the four corners of the base's bottom end. An adjustment mechanism is rotatably connected to the inner wall of the base, and a flipping mechanism is rotatably connected to the top of the adjustment mechanism. A positioning mechanism is fixedly connected to one end of the flipping mechanism. The adjustment mechanism includes a bidirectional threaded rod and two mounting plates. The outer wall of the bidirectional threaded rod is rotatably connected to the inner wall of the base, and the bottom end of the mounting plate is slidably connected to the top end of the base. The flipping mechanism includes two rotating shafts, the outer walls of which are rotatably connected to the top of the mounting plates. The positioning mechanism includes a positioning frame, the outer wall of which is fixedly connected to one end of the rotating shaft, and the inner wall of the positioning frame overlaps the battery protection board body.

[0009] Preferably, the left and right sides of the outer wall of the bidirectional threaded rod are threaded with sliders, the outer wall of the slider is slidably connected to the inner wall of the base, the front and rear ends of the slider are fixedly connected with connecting rods, one end of the connecting rod is fixedly connected to a guide block, the outer wall of the guide block is slidably connected to the inner wall of the base, and the top end of the connecting rod is fixedly connected to the bottom end of the mounting plate.

[0010] Preferably, a guide rod is movably sleeved on the inner wall of the guide block, and one end of the guide rod is fixedly connected to the inner cavity of the base.

[0011] Preferably: a limiting ring is fixedly connected to the outer wall of the rotating shaft on the right side, a connecting block is engaged at the bottom of the limiting ring, and a sliding rod is fixedly connected to both the front and rear parts of the bottom end of the connecting block. A spring is movably sleeved on the outer wall of the sliding rod, the top end of the spring is fixedly connected to the bottom end of the connecting block, a fixing plate is movably sleeved on the outer wall of the sliding rod, the left end of the fixing plate is fixedly connected to the top of the right end of the mounting plate on the right side, and the top end of the fixing plate is fixedly connected to the bottom end of the spring.

[0012] Preferably, a negative pressure fan is fixedly connected to the bottom end of the positioning frame, a rotating rod is rotatably connected to the top end of the positioning frame, a gear is fixedly connected to the bottom of the rotating rod, a toothed plate meshes with the outer wall of the gear, the bottom of the toothed plate is slidably connected to the inner wall of the positioning frame, a clamping plate is fixedly connected to one end of the toothed plate, and the outer wall of the clamping plate overlaps with the outer wall of the battery protection board body.

[0013] Preferably, the inner wall of the toothed plate is slidably connected to a guide strip, and the outer wall of the guide strip is fixedly connected to the inner wall of the positioning frame.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a battery protection board positioning device. By rotating the rotating rod, the rotating rod drives the gear to rotate, so that the gear meshes with the toothed plate, causing the toothed plate to slide on the inner wall of the positioning frame. At the same time, the toothed plate drives the clamping plate to move synchronously. When the outer walls of the front and rear clamping plates are in contact with the outer wall of the battery protection board body, the rotating rod can be stopped. In this way, the front and rear positions of the battery protection board body are fixed and positioned to ensure that the clamping position is in the middle of the battery protection board body.

[0016] 2. This utility model provides a battery protection board positioning device. By pressing the connecting block, the sliding rod slides on the inner wall of the fixed plate, causing the spring to contract and the inner wall of the connecting block to no longer engage with the outer wall of the limiting ring. Then, the rotating shaft can be rotated, causing the limiting ring to rotate synchronously. The rotating shaft drives the positioning frame to rotate synchronously, and the positioning frame drives the battery protection board body to rotate, thereby flipping the battery protection board body. After the flipping is completed, the connecting block is released. Under the action of the spring elastic force, the inner wall of the connecting block engages with the outer wall of the limiting ring again, thereby limiting the rotating shaft and preventing it from rotating, thus ensuring the stability during subsequent processing and achieving the limiting effect.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5 As shown, a battery protection board positioning device includes a base 1, with pads 11 fixedly connected to the four corners of the bottom end of the base 1. An adjustment mechanism 2 is rotatably connected to the inner wall of the base 1, and a flipping mechanism 3 is rotatably connected to the top of the adjustment mechanism 2. A positioning mechanism 4 is fixedly connected to one end of the flipping mechanism 3. The adjustment mechanism 2 includes a bidirectional threaded rod 21 and two mounting plates 26. The outer wall of the bidirectional threaded rod 21 is rotatably connected to the inner wall of the base 1, and the bottom end of the mounting plate 26 is slidably connected to the top end of the base 1. The flipping mechanism 3 includes two rotating shafts 31, and the outer wall of the rotating shaft 31 is rotatably connected to the top of the mounting plate 26. The positioning mechanism 4 includes a positioning frame 41, and the outer wall of the positioning frame 41 is fixedly connected to one end of the rotating shaft 31. The battery protection board body 5 overlaps the inner wall of the positioning frame 41.

[0025] The battery protection board body 5 is positioned by the cooperation of the adjustment mechanism 2 and the positioning mechanism 4. When it is necessary to flip the battery protection board body 5, the flipping operation can be completed by the flipping mechanism 3.

[0026] like Figure 2 As shown, sliders 22 are threadedly connected to both the left and right sides of the outer wall of the bidirectional threaded rod 21. The outer wall of the slider 22 is slidably connected to the inner wall of the base 1. Connecting rods 23 are fixedly connected to both the front and rear ends of the slider 22. A guide block 24 is fixedly connected to one end of the connecting rod 23. The outer wall of the guide block 24 is slidably connected to the inner wall of the base 1. The top end of the connecting rod 23 is fixedly connected to the bottom end of the mounting plate 26.

[0027] By rotating the bidirectional threaded rod 21, the slider 22 slides on the outer wall of the bidirectional threaded rod 21. The slider 22 drives the connecting rod 23 and the guide block 24 to move synchronously. At the same time, the slider 22 and the guide block 24 drive the mounting plate 26 to move synchronously, thereby causing the mounting plate 26 to drive the positioning frame 41 to move synchronously. When the distance between the two positioning frames 41 is appropriate, the battery protection board body 5 is placed between the two positioning frames 41, so that the bottom end of the battery protection board body 5 contacts the inner wall of the positioning frame 41.

[0028] like Figure 2 As shown, a guide rod 25 is movably sleeved on the inner wall of the guide block 24, and one end of the guide rod 25 is fixedly connected to the inner cavity of the base 1.

[0029] When the guide block 24 moves, it slides on the outer wall of the guide rod 25, and the guide rod 25 guides the guide block 24 so that the guide block 24 will not deviate when it moves.

[0030] like Figure 2 , Figure 3As shown, a limiting ring 32 is fixedly connected to the outer wall of the right rotating shaft 31. A connecting block 33 is engaged at the bottom of the limiting ring 32. A sliding rod 34 is fixedly connected to both the front and rear ends of the bottom of the connecting block 33. A spring 35 is movably sleeved on the outer wall of the sliding rod 34. The top end of the spring 35 is fixedly connected to the bottom end of the connecting block 33. A fixing plate 36 is movably sleeved on the outer wall of the sliding rod 34. The left end of the fixing plate 36 is fixedly connected to the top of the right end of the right mounting plate 26. The top end of the fixing plate 36 is fixedly connected to the bottom end of the spring 35.

[0031] By pressing the connecting block 33, the sliding rod 34 slides on the inner wall of the fixed plate 36, causing the spring 35 to contract. This prevents the inner wall of the connecting block 33 from engaging with the outer wall of the limiting ring 32. Then, the rotating shaft 31 can be rotated, causing the limiting ring 32 to rotate synchronously. The rotating shaft 31 drives the positioning frame 41 to rotate synchronously, and the positioning frame 41 drives the battery protection board body 5 to rotate, thereby flipping the battery protection board body 5. After the flipping is completed, the connecting block 33 is released. Under the elastic force of the spring 35, the inner wall of the connecting block 33 engages with the outer wall of the limiting ring 32 again, thereby limiting the rotating shaft 31 and preventing it from rotating. This ensures the stability during subsequent processing and achieves the limiting effect.

[0032] like Figure 2 , Figure 4 As shown, a negative pressure fan 42 is fixedly connected to the bottom of the positioning frame 41, a rotating rod 43 is rotatably connected to the top of the positioning frame 41, a gear 44 is fixedly connected to the bottom of the rotating rod 43, a toothed plate 45 meshes with the outer wall of the gear 44, the bottom of the toothed plate 45 is slidably connected to the inner wall of the positioning frame 41, a clamping plate 47 is fixedly connected to one end of the toothed plate 45, and the outer wall of the clamping plate 47 overlaps with the outer wall of the battery protection board body 5.

[0033] By rotating the rotating rod 43, the rotating rod 43 drives the gear 44 to rotate, causing the gear 44 to mesh with the toothed plate 45, which in turn causes the toothed plate 45 to slide on the inner wall of the positioning frame 41. At the same time, the toothed plate 45 drives the clamping plate 47 to move synchronously. When the outer walls of the front and rear clamping plates 47 are in contact with the outer wall of the battery protection board body 5, the rotating rod 43 can be stopped. This fixes the front and rear positions of the battery protection board body 5, ensuring that the clamping position is in the middle of the battery protection board body 5. Then, the negative pressure fan 42 can be started. The negative pressure fan 42 draws air through the ventilation hole at the bottom of the positioning frame 41, so that the position where the inner wall of the positioning frame 41 overlaps with the battery protection board body 5 is in a negative pressure state, thereby vertically positioning the battery protection board body 5, thus completing the positioning work and achieving the positioning effect.

[0034] like Figure 4 , Figure 5 As shown, a guide strip 46 is slidably connected to the inner wall of the toothed plate 45, and the outer wall of the guide strip 46 is fixedly connected to the inner wall of the positioning frame 41.

[0035] When the toothed plate 45 moves, the guide bar 46 slides on the inner wall of the toothed plate 45, and the guide bar 46 limits the toothed plate 45, making the toothed plate 45 move more smoothly.

[0036] The working principle of this utility model is as follows: In use, based on the size of the battery protection board body 5, the bidirectional threaded rod 21 is rotated, causing the slider 22 to slide on the outer wall of the bidirectional threaded rod 21. The slider 22 drives the connecting rod 23 and the guide block 24 to move synchronously, causing the guide block 24 to slide on the outer wall of the guide rod 25. The guide rod 25 guides the guide block 24, preventing it from shifting during movement. Simultaneously, the slider 22 and the guide block 24 drive the mounting plate 26 to move synchronously, thereby causing the mounting plate 26 to drive the positioning frame 41 to move synchronously. When the distance between the two positioning frames 41 is appropriate, the battery protection board body 5 is placed between the two positioning frames 41, so that the battery protection board body 5... The bottom end of the battery protection board body 5 contacts the inner wall of the positioning frame 41. Then, the bidirectional threaded rod 21 is rotated again, so that one end of the battery protection board body 5 contacts the inner wall of the positioning frame 41, thereby positioning the left and right positions of the battery protection board body 5. Then, the rotating rod 43 is rotated, so that the rotating rod 43 drives the gear 44 to rotate, so that the gear 44 meshes with the toothed plate 45, causing the toothed plate 45 to slide on the inner wall of the positioning frame 41. At the same time, the guide strip 46 slides on the inner wall of the toothed plate 45, and the guide strip 46 limits the toothed plate 45, making the toothed plate 45 move more smoothly. At the same time, the toothed plate 45 drives the clamping plate 47 to move synchronously. The outer walls of the front and rear clamping plates 47 are both in contact with the battery protection board body. When the outer wall of the battery protection board body 5 contacts the battery protection board body 5, the rotation of the rotating rod 43 can be stopped, thereby fixing the front and rear positions of the battery protection board body 5 to ensure that the clamping position is in the middle of the battery protection board body 5. Then, the negative pressure fan 42 can be started. The negative pressure fan 42 draws air through the ventilation hole at the bottom of the positioning frame 41, so that the position where the inner wall of the positioning frame 41 overlaps with the battery protection board body 5 is in a negative pressure state, thereby vertically positioning the battery protection board body 5, thus completing the positioning work and achieving the positioning effect. Then, the work can begin. When it is necessary to process the reverse side of the battery protection board body 5, press down the connecting block 33 to drive the sliding rod 34 to the fixed plate. The inner wall of 36 slides, causing the spring 35 to contract, so that the inner wall of the connecting block 33 is no longer inserted into the outer wall of the limiting ring 32. Then the rotating shaft 31 can be rotated, causing the limiting ring 32 to rotate synchronously. The rotating shaft 31 drives the positioning frame 41 to rotate synchronously, and the positioning frame 41 drives the battery protection board body 5 to rotate, thereby flipping the battery protection board body 5. After the flipping is completed, the connecting block 33 is released. Under the action of the elastic force of the spring 35, the inner wall of the connecting block 33 is inserted into the outer wall of the limiting ring 32 again, thereby limiting the rotating shaft 31 and preventing it from rotating, so as to ensure the stability during subsequent processing and achieve the limiting effect, thus greatly improving the user experience.
