Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a coating correction device for emergency start-up batteries. Background Technology

[0002] An emergency jump starter battery is a portable backup power device that provides instantaneous high-current starting power when a vehicle's battery is depleted. It typically uses a rectangular aluminum shell structure. The metal shell itself is conductive. When the battery is assembled into a module, multiple batteries are arranged closely together. If the shells come into direct contact, it is very easy to cause a short circuit between the positive and negative electrodes. Therefore, during the battery manufacturing process, a protective film is wrapped around the battery to effectively isolate the negative electrode inside the battery from the metal shell (aluminum shell). This helps to prevent electrochemical corrosion caused by direct contact and also effectively blocks the external environment from corroding the battery. In the existing semi-automatic coating process, due to the wide width of the protective film and the flexibility of the material, uneven manual tensioning can easily cause the protective film to accumulate and form wrinkles in the middle due to excessive stretching. If the wrinkles are not corrected and smoothed in time, the protective film will not adhere tightly to the battery surface, thus affecting the quality of the battery coating. Furthermore, after a battery is coated, the protective film usually needs to be cut manually. The automation level of film cutting is low, which is not conducive to automatically cutting the protective film while correcting it to a straight state, thereby improving the overall efficiency of battery coating. Summary of the Invention

[0012] Optionally, limit plates are fixed on both sides of the top of the workbench, and the limit plates are symmetrically arranged on both sides of the conveyor belt length direction.

[0013] Optionally, cylinders are provided at intervals on the limiting plates on both sides.

[0014] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: 1. By setting a pair of correction blocks and using a transmission chain to drive the pair of correction blocks to perform a reciprocating lateral prying action from the middle to both sides, the wrinkles on the film can be automatically smoothed from the middle to both sides, making it easier to correct the battery protective film into a flat state, ensuring the flatness of the emergency start battery film, effectively preventing wrinkles in the middle of the protective film from affecting the film coating effect due to uneven tension control, and in the initial state, the correction blocks are tilted and rotatable against the surface of the protective film, making it easy for the correction blocks to flexibly smooth the protective film.

[0015] 2. By driving the correction blocks downward, the protective film is pressed firmly to the edge of the second battery. Then, the correction blocks on both sides are driven to move to opposite sides again, so that the protective film adheres to the edge of the second battery. This achieves pre-coating of the second battery. After pre-coating, the protective film is cut from the middle of the two batteries by the blade. At this time, the free end of the protective film can be pre-attached to the edge of the second battery, which to a certain extent saves manual re-alignment of the free end of the protective film and facilitates the subsequent pressing and smoothing operation. While correcting the position of the protective film, it helps to shorten the waiting time between loading and unloading, and further improves the overall processing efficiency of the device for correction and coating.

[0016] 3. By setting a retractable blade inside the calibration block, when the second battery is pre-coated by the calibration block, the rotation of the calibration block will squeeze the arc-shaped rod, causing the gas inside the arc-shaped sleeve to be squeezed into the cavity, which in turn pushes piston rod one and piston rod two downward, pushing the blade out. Thus, the cutting is automatically completed as the calibration blocks on both sides move to the sides, eliminating the need for manual cutting of the protective film in the semi-automatic coating device. In addition, the two blades are misaligned and not on the same plane. The blades can also rotate at a certain tilt angle towards the center of the protective film, making it easier to cut the protective film between the two blades in the middle of the protective film. After the cutting is completed, when the calibration block moves in the reverse direction to reset, the calibration block rotates in the reverse direction, spring two pushes the calibration block to reset, the arc-shaped rod is pulled out, the gas in the cavity is drawn back into the arc-shaped sleeve, and the blade retracts back into the movable cavity, realizing blade storage.

Detailed Implementation

[0020] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0022] See Figures 1 to 11As shown, in one embodiment of the present invention, a protective film alignment device for an emergency start battery includes a workbench 100, with a conveyor belt 110 for transporting batteries arranged along the length of the top center of the workbench 100; a film pressing assembly 200 is arranged at one end of the top of the workbench 100, which is used to press the protective film tightly against the battery surface. The film pressing assembly 200 includes a gantry frame 201 slidably arranged above the workbench 100, with a pressure roller 202 arranged in the middle of the gantry frame 201; and an alignment assembly 300 is also arranged above the workbench 100 to smooth out wrinkles on the protective film. The alignment assembly 300 includes a pair of transmission chains 314, a drive assembly 330, and a pair of alignment components. The correction block 340 is connected to the drive chain 314 and the drive assembly 330. The drive assembly 330 drives the drive chains 314 on both sides to rotate in opposite directions. The correction block 340 is movably connected to the drive chain 314 through the movable member 320. The drive chain 314 drives a pair of correction blocks 340 to perform a reciprocating lateral plucking action above the protective film. The path of this action is from the middle to both sides to smooth out the wrinkles on the protective film. The correction assembly 300 is provided with a cutting assembly 500, including a blade 511 movably disposed inside the correction block 340. After the plucking and smoothing work is completed, the blade 511 can move synchronously with the correction block 340 to automatically cut the protective film.

[0023] During operation, the robot first places the emergency starter battery to be processed onto the conveyor belt 110, which then transports the battery to the processing station. The free end of the protective film is pulled out from the roller, then wrapped around the bottom of the correction block 340 and adhered to the first narrow side of the battery. Next, the gantry frame 201 and pressure roller 202 are moved. The pressure roller 202 is elastically connected to the gantry frame 201 via a return spring. The pressure roller 202 can adapt to batteries of different heights, stably pressing and adhering the protective film to the battery surface, preventing... The protective film curls up and wrinkles. The pressure roller 202 is used to press the protective film tightly against the first wide side of the battery. Then the battery is flipped over, and the protective film is pressed tightly against the second narrow side. The first wide side of the battery is then placed flat on the conveyor belt 110 with the first wide side facing down. The pressure roller 202 is used again to press the protective film tightly against the second wide side of the battery. Then the blade 511 extends out from the correction block 340. As the correction block 340 moves to both sides, it directly cuts the protective film. Finally, the free end of the cut protective film is pressed tightly against the outside of the first narrow side of the battery to complete the wrapping operation.

[0024] The drive assembly 330 drives the two transmission chains 314 to rotate in opposite directions. The transmission chains 314 drive a pair of correction blocks 340 to perform a reciprocating lateral plucking motion above the protective film. The movement trajectory of the correction blocks 340 is similar to the shape of the transmission chains 314. When the correction blocks 340 move to the end of the transmission chain 314 corresponding to the middle position of the protective film, the correction blocks 340 move downward and contact the upper surface of the protective film, and then smooth the protective film to both sides, pushing away the wrinkles. When the correction blocks 340 move to the other end of the transmission chain 314, the correction blocks 340 will then move upward and no longer squeeze the protective film, until they move to the middle position above the protective film, completing the repeated lateral plucking motion of pressing down and smoothing - lateral movement - lifting and separating - lateral movement - pressing down and smoothing, which is used to continuously smooth the wrinkles on the protective film.

[0025] See Figures 1 to 4 As shown, in one embodiment of the present invention, the correction component 300 further includes a moving component 310. The moving component 310 includes electric slide rails 315 symmetrically arranged on both sides of the conveyor belt 110. A gantry frame 311 is fixed above the electric sliders of the electric slide rails 315 on both sides. The position of the correction component 300 can be adjusted by the electric slide rails 315. A crossbeam 312 is slidably arranged in the middle of the gantry frame 311. A sprocket for driving the chain to rotate is rotatably installed in the groove provided on the side wall of the crossbeam 312. A cylinder 313 for driving the crossbeam 312 to move up and down is fixedly arranged on the gantry frame 311.

[0026] During operation, the conveyor belt 110 continuously transports batteries. While the first battery is being coated, a second battery is placed adjacent to it. The pressure roller 202 then presses the protective film against the second wide edge of the first battery. Next, cylinder 313 drives the crossbeam 312 downwards, simultaneously moving the alignment blocks 340 downwards to press the protective film against the edge of the second battery. Then, the two alignment blocks 340 are driven to move to opposite sides, ensuring the protective film adheres to the edge of the second battery. This completes the pre-coating of the second battery. After pre-coating, the alignment block 340 moves to the middle of the protective film again. At this time, the blade 511 extends outward and moves from the middle to both sides along with the alignment block 340, separating the protective film from the middle of the two batteries. At this time, the free end of the protective film has been pre-attached to the edge of the second battery, so the free end of the protective film will not move randomly. The worker only needs to pull the second battery to the processing position. There is no need to re-align and attach it. The subsequent pressing and smoothing operation can be carried out directly, which shortens the waiting time between loading and unloading and improves the overall processing efficiency of the device.

[0027] See Figure 11As shown, in one embodiment of the present invention, the drive assembly 330 includes a first gear 332 and a second gear 333. The first gear 332 and the second gear 333 are coaxially and fixedly connected to the sprockets provided at the adjacent ends of the transmission chains 314 on both sides. The first gear 332 and the second gear 333 mesh with each other. A housing 331 is fixed to the outside of the first gear 332 and the second gear 333. A motor is fixed to the outside of the housing 331. A third gear 334 is fixed on the output shaft of the motor. The third gear 334 meshes with the first gear 332.

[0028] When the motor is started, the motor drives the gear 1 332 to rotate through the gear 3 334. The gear 1 332 drives the gear 2 333 to rotate synchronously in the opposite direction, thereby driving the transmission chains 314 on both sides to rotate in opposite directions. This ensures that the correction blocks 340 on both sides can move synchronously from the middle to both sides, resulting in higher synchronization of the operation.

[0029] See Figure 4-5 As shown, in one embodiment of the present invention, the movable component 320 includes a vertical L-shaped plate 321. The upper part of the L-shaped plate 321 is movably connected to the transmission chain 314 via a connecting rod. The connecting rod is fixed to the side wall of one of the hinge shafts connected to the transmission chain 314. An L-shaped plate 322 is provided on the side of the L-shaped plate 321 away from the crossbeam 312. An L-shaped plate 323 is fixed on the side wall of the vertical section of the L-shaped plate 322. The L-shaped plate 323 passes through a groove opened on the vertical section of the L-shaped plate 321. A roller 327 is rotatably mounted in the middle of the L-shaped plate 323. Shaft 327 abuts against the lower surface of crossbeam 312; L-shaped plate 324 is fixed to the top of L-shaped plate 2 322, and the horizontal section of L-shaped plate 4 324 is pressed against the inner wall of the bottom of the groove; a sliding rod 325 is slidably installed in the sliding hole in the middle of the horizontal section of L-shaped plate 2 322, the bottom of the sliding rod 325 is fixed to the horizontal section of L-shaped plate 1 321, and a spring 1 is sleeved on the sliding rod 325; a vertical rod 326 is fixed below the horizontal section of L-shaped plate 1 321, and a correction block 340 is rotatably installed at the bottom of the vertical rod 326, and a spring 2 is fixed between the correction block 340 and the vertical rod 326.

[0030] During operation, the L-shaped plate 322 and roller 327 are respectively clamped on the inner and outer sides of the bottom of the groove of the crossbeam 312 to limit the movement direction of the movable part 320. When the correction block 340 is driven to move laterally by the transmission chain 314, the movable part 320 moves linearly along the length of the crossbeam 312. When the movable part 320 moves to the bend at the end of the transmission chain 314, the transmission chain 314 provides a vertical driving force to the L-shaped plate 321. When the movable part 320 moves to the end of the transmission chain 314 away from the middle of the protective film, the movable part 320 moves upward under force, and the L-shaped plate 321 moves upward. At this time, the spring is compressed. When the movable part 320 moves with the transmission chain 314 to the middle position of the protective film, the L-shaped plate 321 moves downward, and the spring returns to its original position.

[0031] In addition, by setting a second spring between the correction block 340 and the vertical rod 326, the correction block 340 can achieve elastic contact with the protective film, maintain stable pressure on the protective film, and avoid rigid extrusion that scratches the surface of the protective film.

[0032] See Figures 6 to 10 As shown, in one embodiment of the present invention, the cutting assembly 500 further includes an arc-shaped sleeve 501 fixed to the side wall of the vertical rod 326. An arc-shaped rod 502 is slidably installed inside the arc-shaped sleeve 501, and one end of the arc-shaped rod 502 is fixedly connected to the correction block 340. Movable cavities are opened at the bottom of the opposite side walls of the two correction blocks 340, and the blade 511 is disposed inside the movable cavity. A cavity is opened inside the correction block 340 and above the blade 511. A sliding cavity 1 507 and a sliding cavity 2 509 are opened below the cavity. A piston rod 1 508 is slidably installed inside the sliding cavity 1 507, and a piston rod 2 510 is slidably installed inside the sliding cavity 2 509. The bottoms of the piston rod 1 508 and the piston rod 2 510 are respectively movably connected to the blade 511. An air passage 506 is provided on the side of the cavity, and the end of the air passage 506 away from the cavity is fixedly connected to the arc-shaped sleeve 501 through a hose 503.

[0033] A buffer 504 is fixed in the middle of the hose 503. The buffer 504 is a hollow airbag made of elastic rubber. A solenoid valve 505 is provided at the connection between the hose 503 and the airway 506.

[0034] The blades 511 inside the two correction blocks 340 are staggered to facilitate the overlapping of the blades 511 on both sides towards the middle.

[0035] During operation, initially, the angle between the calibration block 340 and the vertical rod 326 is greater than 90 degrees. When the calibration block 340 needs to press the protective film onto the top edge of the second battery, the solenoid valve 505 is closed, controlling the calibration block 340 to move downwards until it contacts the second battery. At this point, the calibration block 340 is squeezed and rotates, becoming perpendicular to the vertical rod 326. The calibration block 340 is horizontally attached to the surface of the second battery, facilitating the pressing of the protective film onto the battery. Simultaneously, during the rotation of the calibration block 340, the arc-shaped rod 502 is pushed towards the inside of the arc-shaped sleeve 501, forcing the air inside the arc-shaped sleeve 501 into the buffer 504 through the hose 503. Because the hose 503 is blocked by the solenoid valve 505, the air accumulates in the inner cavity of the buffer 504, causing the buffer 504 to deform and expand. After the pre-coating operation of the second battery is completed... The two correction blocks 340 are driven to move simultaneously to the middle position of the protective film, while still maintaining horizontal contact with the surface of the second battery. At this time, the control solenoid valve 505 is turned on, and the buffer 504 retracts and resets under its own elasticity, thereby forcing out the air in the inner cavity. The air enters the air passage 506 inside the correction block 340 through the hose 503, then enters the cavity, and then is introduced into the sliding cavity 1 507 and sliding cavity 2 509 respectively, pushing the piston rod 1 508 and piston rod 2 510 to move down synchronously, thereby protruding the blade 511 from the bottom of the movable cavity outward and inserting it into the protective film. Since the stroke of sliding cavity 1 507 is less than the stroke of sliding cavity 2 509, the piston rod 1 508 located inside sliding cavity 1 507 stops moving first, while piston rod 2 510 continues to move, and its end moves in the waist groove on the blade 511, thereby causing the blade 511 to deflect about the hinge point at the bottom end of piston rod 1 508 as the origin. Figure 8 As shown, the blades 511 inside the two correction blocks 340 can be driven to deflect synchronously towards the middle position in the above manner, thereby cutting the protective film at the adjacent positions of the two correction blocks 340, avoiding the situation where the protective film is not cut in the middle position, and saving the manual subsequent recutting operation; finally, the two blades 511 move synchronously to both sides with the correction blocks 340 to achieve complete cutting of the protective film.

[0036] In addition, such as Figure 7As shown, elastic ropes are fixedly installed at the top of piston rod 508 and piston rod 510 respectively. When piston rod 508 and piston rod 510 are pushed downward, the elastic ropes are stretched. After the splitting action is completed, the crossbeam 312 and the correction block 340 below are lifted and reset again by cylinder 313. Then, under the action of spring 2, the angle between correction block 340 and vertical rod 326 is increased. At this time, the arc rod 502 moves outward relative to the arc sleeve 501, generating negative pressure in the inner cavity of the arc sleeve 501. Then, piston rod 508 and piston rod 510 retract in opposite directions into the corresponding sliding cavity, which facilitates the retraction of blade 511. At the same time, the elastic rope is pulled back synchronously to assist the retraction of blade 511.

[0037] See Figure 2 As shown, in one embodiment of the present invention, a guide roller 400 is slidably disposed in the middle of the gantry frame 201, and cylinders 410 for driving the guide roller 400 to move up and down are symmetrically fixed on the outer walls of both sides of the gantry frame 201.

[0038] During operation, the guide roller 400 is positioned above the center of the protective film. The guide roller 400 pre-presses and limits the center of the protective film, reducing excessive vertical swing of the protective film and ensuring that the correction block 340 can accurately contact the predetermined position of the protective film, thereby improving the stability of the smoothing operation.

[0039] See Figure 2 As shown, in one embodiment of the present invention, limit plates 120 are fixed on both sides of the top of the workbench 100, and the limit plates 120 are symmetrically arranged on both sides of the conveyor belt 110 along its length.

[0040] During operation, the limiting plate 120 can limit and align the batteries placed on the conveyor belt 110, preventing the batteries from tilting during transportation and ensuring the accuracy of subsequent wrapping and correction operations.

[0041] See Figure 2 As shown, in one embodiment of the present invention, cylinders 130 are provided at intervals on the two limiting plates 120.

[0042] During operation, multiple cylinders (130) can be used to limit the movement of the battery during transport, ensuring that the first and second batteries move precisely to the designated positions.

[0043] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
