Description

Technical Field

[0001] This invention relates to the field of protection board processing technology, specifically to a device for the simultaneous processing of sheathing assembly and wire threading of battery component terminals. Background Technology

[0002] The battery protection board (battery control board) is a core safety component of lithium batteries. It uses control ICs and switching transistors to provide protection against overcharge, over-discharge, short circuit, and over-temperature.

[0003] To ensure a stable connection between the wire and the protection board, the wire is usually passed through the reserved wire hole on the protection board (8). Then, the end of the wire is bent manually so that the wire core passes through the round hole pad before welding. The wire hole design is to increase the friction between the wire insulation layer and the wire hole, thereby improving the connection strength between the wire and the protection board. The existing wire bending and hole process relies on manual operation. The insulation sleeve needs to be put on the wire first before the hole and bending operations are performed. In summer, the wire is easier to bend, while in the cold season, the wire hardness increases and it is not easy to bend, resulting in a lot of physical effort being consumed in the bending process. Long-term work can easily lead to finger pressure injury. Therefore, in the cold season, the insulation layer of the wire needs to be softened by the heating gun before bending. The heating gun process increases the processing time, thereby reducing production efficiency. For this reason, we propose a device for simultaneous processing of sheath fitting and wire threading of battery component terminals. The insulating sleeve of the terminal has a constricted end and an flared end. When assembling the insulating sleeve manually, it is easy to put the insulating sleeve in reverse, which prevents the insulating sleeve from effectively covering the flared end of the terminal, thus affecting the quality of the product. Summary of the Invention

[0004] The purpose of this invention is to provide a device for the simultaneous assembly and threading of sheaths for battery component terminals, addressing the issues raised in the background art where, in cold seasons, bending of wires requires softening with a heat gun, which affects production efficiency. Furthermore, bending and threading operations rely on manual labor, which can cause pressure injuries to workers' hands over extended periods. Manual bending also results in significant labor costs and the risk of incorrect installation of insulating sheaths. To achieve the above objectives, this invention provides the following technical solution: a device for the simultaneous assembly and threading of sheaths for battery component terminals, comprising a base plate and a protective plate. A bending and flipping assembly for bending wires at 180 degrees is provided on one side of the top of the base plate. A lateral movement assembly, which moves the protective plate laterally via the bending and flipping assembly, is provided on the top of the base plate. A positioning clamping assembly, which positions and holds the protective plate, is provided on top of the positioning clamping assembly. A drive mechanism for driving the bending and flipping assembly is provided at the bottom of the base plate. The component has a groove that runs from top to bottom through the interior of the base plate. The bending and flipping component consists of a bending part and a flipping part. The bending part includes a support member fixedly connected to the top of the base plate. A rotating shaft is rotatably connected to the inside of the support member via a bearing. A bending sleeve for bending the wire is fixedly connected to one end of the rotating shaft, and an eccentric block is fixedly connected to the other end of the rotating shaft. An eccentric shaft is fixedly connected to the side of the eccentric block away from the rotating shaft. A bushing is rotatably sleeved on the outer wall of the eccentric shaft via a bearing. A stop bar is fixedly connected to the top of the support member near the bending sleeve.

[0005] More preferably, the protective plate has multiple through holes for the wires to pass through completely.

[0006] More preferably, the flipping part includes a slide table slidably connected in the slide groove. The slide table has a guide groove that is transversely and completely penetrates the slide table. The guide groove is slidably connected to the bushing. Multiple upper pulleys are rotatably connected to the opposite side of the slide table, and the upper pulleys are located at the top of the base plate. A lower pulley is rotatably connected to the bottom of the opposite side of the slide table, and the lower pulley is located at the bottom of the base plate.

[0007] More preferably, the transverse assembly includes two fixed seats fixedly connected to the top of the base plate. A slide rod is fixedly connected to one side of each fixed seat. A slide block is slidably connected to the outer wall of the two slide rods. Two movable grooves corresponding to the positions of the slide rods are opened on the side of the slide block near the fixed seat. A spring abuts against one side of the inner wall of one side of the movable groove and one side of the fixed seat, and the spring is movably sleeved on the slide rod. A limiting plate for limiting the travel of the slide block is fixedly connected to the top of the base plate. The side of the slide block away from the fixed seat abuts against one side of the limiting plate by the force of the spring. A pull plate is fixedly connected to one side of the slide block.

[0008] More preferably, the positioning and clamping assembly consists of a positioning part and a clamping part. The positioning part includes a clamping platform fixedly connected to the top of the slide, and a positioning plate is fixedly connected to the side of the clamping platform near the slide.

[0009] More preferably, the clamping part comprises an internally threaded sleeve fixedly connected to one side of the top of the clamping table, an adjusting screw is internally threaded to the internally threaded sleeve, a knob is fixedly connected to the end of the adjusting screw away from the clamping table, a backing plate is fixedly connected to the end of the adjusting screw near the clamping table, and a gasket is fixedly connected to the side of the backing plate near the clamping table.

[0010] More preferably, a support plate is fixedly connected to the side of the slide away from the fixed seat, and a placement platform is fixedly connected to the top of the support plate. An insulating sleeve is placed in each of the two grooves on the top of the placement platform, and the grooves on the top of the placement platform are adapted to the contours of the insulating sleeves.

[0011] More preferably, the drive assembly includes a hydraulic push rod fixedly connected to the bottom of the base plate, the output end of the hydraulic push rod being fixedly connected to a connecting plate, and the side of the connecting plate near the hydraulic push rod being fixedly connected to the bottom of one side of the slide table.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the bending and flipping assembly, the lateral movement assembly, and the driving assembly eliminate the need for manual bending operations. The bending and flipping assembly, driven by a hydraulic pusher, bends the end of the wire. The lateral movement assembly then guides the wire core through the circular pad on the protective plate, followed by soldering. This eliminates the need for manual bending; personnel only need to guide the wire to the appropriate distance and activate the hydraulic pusher for automatic bending and insertion of the wire core into the circular pad. Finally, manual soldering is performed. Compared to manual bending, this significantly reduces physical exertion and avoids pressure injuries to the hands, ensuring worker health and preventing hand discomfort. It also eliminates the need for heating and softening with a hot gun in cold weather, thus greatly improving production efficiency.

[0013] In this invention, by placing the insulating sleeve on the path of the conductor, the bending and welding of the conductor and the assembly of the insulating sleeve are completed simultaneously, thereby making the work process continuous and improving production efficiency. Furthermore, the groove of a specific shape on the placement table prevents the insulating sleeve from being placed backwards during the placement process. The foolproof design prevents the incorrect installation during human assembly, thereby improving product quality. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-8This invention provides a technical solution: a device for synchronously processing the sheathing and wiring of battery component terminals, comprising a base plate 1 and a protective plate 8. A bending and flipping assembly for bending the wire at 180 degrees is provided on one side of the top of the base plate 1. A lateral movement assembly is provided on the top of the base plate 1, which drives the protective plate 8 to move laterally via the bending and flipping assembly. A positioning clamping assembly for positioning and holding the protective plate 8 is provided on the top of the lateral movement assembly, and the protective plate 8 is located on top of the positioning clamping assembly. A driving assembly for driving the bending and flipping assembly is provided at the bottom of the base plate 1. The interior of the base plate 1 has openings from top to bottom... The sliding groove 11 completely penetrates the base plate 1. The bending and flipping assembly consists of a bending part and a flipping part. The bending part includes a support member 3 fixedly connected to the top of the base plate 1. The support member 3 has a rotating shaft 31 rotatably connected to the inside through a bearing. One end of the rotating shaft 31 is fixedly connected to a bending sleeve 32 for bending the wire. The other end of the rotating shaft 31 is fixedly connected to an eccentric block 33. An eccentric shaft 34 is fixedly connected to the side of the eccentric block 33 away from the rotating shaft 31. A bushing 35 is rotatably sleeved on the outer wall of the eccentric shaft 34 through a bearing. A stop bar 36 is fixedly connected to the top of the support member 3 on the side near the bending sleeve 32. The positioning clamping assembly is used to clamp and position the protection board 8, and the bending and flipping assembly is used to bend one end of the wire connected to the protection board 8. After the wire is bent, the positioning clamping assembly moves closer to the rotating shaft 31 through the cooperation of the lateral movement assembly and the bending and flipping assembly, so that the wire core is inserted into the through hole circular pad of the protection board 8. The eccentric shaft 34 and the rotating shaft 31 are eccentrically set. In the default state, the rotating shaft 31 is located above the eccentric shaft 34. The bending sleeve 32 is U-shaped. In the default state, the opening of the bending sleeve 32 faces upward. The outer wall of the stop bar 36 is provided with a limiting groove that matches the contour of the wire, so as to ensure that the wire position will not shift during the bending process of the bending sleeve 32.

[0018] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, the protective plate 8 has multiple through holes 81 for wires to pass through completely.

[0019] In this embodiment, as Figure 1 , Figure 6 and Figure 8 As shown, the flipping part includes a slide table 2 slidably connected in the slide groove 11. The slide table 2 has a guide groove 22 that is completely transversely connected to the slide table 2. The guide groove 22 is slidably connected to the bushing 35. Multiple upper pulleys 21 are rotatably connected to the opposite side of the slide table 2. The upper pulleys 21 are located at the top of the base plate 1. Lower pulleys 23 are rotatably connected to the bottom of the opposite side of the slide table 2. The lower pulleys 23 are located at the bottom of the base plate 1. By limiting the slide table 2 with two upper pulleys 21 and one lower pulley 23, the slide table 2 can only move laterally along the slide groove 11 and the friction force when the slide table 2 moves is reduced, so that the slide table 2 moves smoothly and stably. The guide groove 22 consists of an inclined groove and a horizontal groove, with the horizontal groove and the rotating shaft 31 on the same horizontal line; During the lateral movement of the slide table 2 driven by the drive assembly, the inclined groove pushes the bushing 35, causing the bushing 35 to slide along the inclined groove. At the same time, the inclined groove pushes the bushing 35 and the eccentric shaft 34, causing the eccentric shaft 34 to deflect around the rotating shaft 31. When the bushing 35 enters the guide groove 22, the eccentric shaft 34 and the rotating shaft 31 are on the same horizontal line, causing the rotating shaft 31 to rotate 90 degrees. Since the bending sleeve 32 is U-shaped, the inner wall of the bending sleeve 32 pushes the wire, causing the wire to bend 180 degrees around the stop bar 36, so that the wire core at the end of the wire faces the through hole circular pad on the protection plate 8.

[0020] In this embodiment, as Figure 6 , Figure 7 and Figure 8 As shown, the transverse assembly includes two fixed seats 44 fixedly connected to the top of the base plate 1. A slide rod 43 is fixedly connected to one side of the fixed seat 44. A slide block 4 is slidably connected to the outer wall of the two slide rods 43. Two movable grooves 41 corresponding to the positions of the slide rods 43 are opened on the side of the slide block 4 near the fixed seat 44. A spring 42 is abutted between the inner wall of one side of the movable groove 41 and one side of the fixed seat 44. The spring 42 is movably sleeved on the slide rod 43. A limiting plate 46 for limiting the stroke of the slide block 4 is fixedly connected to the top of the base plate 1. The side of the slide block 4 away from the fixed seat 44 is abutted against one side of the limiting plate 46 by the force of the spring 42. A pull plate 45 is fixedly connected to one side of the slide table 2. The sliding trajectory of the slide block 4 is restricted by two slide rods 43, so that the slide block 4 can only move along the longitudinal direction of the slide rods 43. Spring 42 always provides elastic force, pushing slide 4 against limit plate 46; As soon as the bushing 35 enters the transverse groove, the L-shaped pull plate 45 continues to move with the slide table 2, causing the bushing 35 to slide along the transverse groove. At this time, the L-shaped pull plate 45 also abuts against the side of the slide block 4 near the positioning plate 51. As the slide table 2 continues to move, the pull plate 45 also moves synchronously and overcomes the elastic force of the spring 42 to pull the slide block 4 towards the fixed seat 44. During this process, the exposed wire core at the end of the wire gradually approaches and passes through the through hole circular solder pad until the bushing 35 moves to the end of the transverse groove and stops. At this time, the personnel use welding tools to weld the wire core to the through hole circular solder pad, so that the wire and the protective plate 8 are welded and fixed.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the positioning and clamping assembly consists of a positioning part and a clamping part. The positioning part includes a clamping platform 5 fixedly connected to the top of the slide 4. A positioning plate 51 is fixedly connected to the side of the clamping platform 5 near the slide 2. The clamping platform 5 is L-shaped and consists of a horizontal plate and a vertical plate. The positioning plate 51 and the vertical plate are used to limit and position the protective plate 8.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the clamping part comprises an internally threaded sleeve 53 fixedly connected to one side of the top of the clamping table 5. An adjusting screw 54 is connected to the internal thread of the internally threaded sleeve 53. A knob 55 is fixedly connected to the end of the adjusting screw 54 away from the clamping table 5. A backing plate 56 is fixedly connected to the end of the adjusting screw 54 near the clamping table 5. A gasket 57 is fixedly connected to the side of the backing plate 56 near the clamping table 5. The gasket 57 is a rubber gasket. By rotating the adjusting screw 54, the abutment 56 pushes the protective plate 8 through the gasket 57, thereby clamping the protective plate 8 by the gasket 57 and the upright plate, thus fixing the protective plate 8. At the same time, the gasket 57 achieves soft contact with the protective plate 8, thereby avoiding damage to the protective plate 8 caused by rigid force during clamping.

[0023] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a support plate 6 is fixedly connected to the side of the slide block 4 away from the fixed base 44. A placement platform 61 is fixedly connected to the top of the support plate 6. An insulating sleeve 62 is placed in two grooves on the top of the placement platform 61, and the grooves on the top of the placement platform 61 are adapted to the contour of the insulating sleeve 62. The insulating sleeve 62 is placed manually in the groove of the placement platform 61. The exposed end of the conductor core is then passed through the insulating sleeve 62 and the wire hole 81 on the protective plate 8 in sequence, so that the insulating sleeve 62 is assembled before the conductor is bent, thereby realizing the simultaneous assembly of the insulating sleeve 62 and the conductor bending and welding operations.

[0024] In this embodiment, as Figure 5 As shown, the drive assembly includes a hydraulic push rod 7 fixedly connected to the bottom of the base plate 1, and a connecting plate 71 fixedly connected to the output end of the hydraulic push rod 7. The side of the connecting plate 71 closest to the hydraulic push rod 7 is fixedly connected to the bottom of one side of the slide table 2. The hydraulic push rod 7 is used to drive the slide table 2 to move laterally, so as to realize the bending and flipping assembly to bend the end of the wire and drive the lateral movement assembly and the protective plate 8 to approach the bent end of the wire. After the protective plate 8 and the wire are welded, the hydraulic push rod 7 is started in reverse, so that the output end of the hydraulic push rod 7 retracts, which is used to reset the bending and flipping assembly and the lateral movement assembly.

[0025] The method of use and advantages of this invention: The protective sleeve of the battery component terminal is equipped with a wire threading synchronous processing device. During use, the working process is as follows: When in use, first place the protective plate 8 on the clamping table 5, then push the protective plate 8 horizontally so that its side abuts against the positioning plate 51, then turn the knob 55 so that the adjusting screw 54 rotates, thereby allowing the shim 57 to push against the protective plate 8, so that the protective plate 8 is clamped and fixed between the upright plate and the shim 57. Then place the insulating sleeve 62 on the groove of the placement platform 61. The flared end of the insulating sleeve 62 should be placed on the side away from the protective plate 8. Then manually pass the wire through the insulating sleeve 62 and the wire hole 81 in sequence. After passing through an appropriate distance, start the hydraulic push rod 7. After the hydraulic push rod 7 is started, its output end extends outward, driving the slide table 2 to slide along the slide groove 11; as the inclined groove of the guide groove 22 generates a pushing force on the bushing 35, the rotating shaft 31 gradually rotates. When the bushing 35 enters the horizontal groove, the rotating shaft 31 rotates ninety degrees. At this time, the bending sleeve 32 also flips ninety degrees. The bending sleeve 32 flips from bottom to top, and the stop rod 36 limits the wire, so that the end of the wire bends one hundred and eighty degrees around the stop rod 36. This allows the slide block 4 to overcome the elastic force of the spring 42 and move closer to the fixed seat 44 until the wire core at the end of the wire is inserted into the through-hole circular solder pad. Then, the solder pad and the wire core are soldered manually. After the soldering is completed, the knob 55 and the adjusting screw 54 are rotated in the opposite direction to release the clamping plate 56 and the gasket 57 from the protective plate 8. Then, the end of the wire near the terminal is lifted to disengage the insulating sleeve 62 from the groove on the placement platform 61. Then, the protective plate 8 is pulled away from one side of the clamping platform 5. Finally, the end of the wire near the terminal is pulled to tighten the bent part of the wire. At this point, the wire and the protective plate 8 have completed the assembly of the insulating sleeve 62, the bending of the wire, the threading and the soldering operations simultaneously.
