[0002] When producing cylindrical batteries, it is necessary to install a heat shrink tubular film on the outer shell and heat it so that the tubular film shrinks tightly and covers the outer surface of the battery, and exposes the two ends of the cylindrical battery, thereby providing better protection and aesthetic effects for the battery. Some existing battery film coating equipment includes a conveyor line, a film coating mechanism, and a heating device. The battery is placed on the conveyor line in advance, and then the conveyor line transports the battery on it to the film coating mechanism.

[0036] Reference Figures 1 to 6 , which is a battery film coating device according to an embodiment of the utility model, includes a base 100, a conveying device 200, a film coating mechanism 300, a tube film positioning device 400 and a heating device 500. The conveying device 200 is arranged on the machine base 100; the film sleeve mechanism 300 is arranged on the machine base 100 and can sleeve the tubular film on the battery on the conveying device 200; the tubular film positioning device 400 is arranged on the machine base 100, the film sleeve mechanism 300 and the tubular film positioning device 400 are arranged along the conveying direction of the conveying device 200, the tubular film positioning device 400 includes a clamping mechanism 410 and a tubular film pushing mechanism 420, the clamping mechanism 410 is provided with a battery clamping position, the tubular film pushing mechanism 420 includes a tubular film pushing piece 421 and a pushing driver 422, the pushing driver 422 is used to drive the tubular film pushing piece 421 to move toward or away from the battery clamping position to adjust the position of the tubular film relative to the battery, and the conveying device 200 passes through the battery clamping position along the conveying direction; the heating device 500 is arranged on the machine base 100, and the conveying device 200 passes through the battery clamping position and the workstations corresponding to the heating device 500 in sequence along the conveying direction.

[0037] The film sleeve mechanism 300 sleeves the tubular film on the periphery of the battery, and then the conveying device 200 conveys the battery to the battery clamping position of the tubular film positioning device 400, and then the clamping mechanism 410 clamps the battery, and the push driver 422 drives the tubular film pusher 421 to move toward the battery clamping position to push the tubular film into place, and then the tubular film pusher 421 is reset and the clamping mechanism 410 releases the battery, and the battery is conveyed to the heating device 500 through the conveying device 200 to perform heat shrinkage on the tubular film; the above structure, by adding the tubular film positioning device 400, reduces the risk of the tubular film not being properly sleeved relative to the battery, thereby improving the production yield of the battery film sleeve equipment.

[0038] In the embodiment, the conveying direction of the conveying device 200 is from front to back, and the clamping mechanism 410 and the tube film pushing mechanism 420 are respectively arranged on the left and right sides of the conveying device 200. The battery covered with the film of the utility model includes a battery body and an input and output connector protruding from one end of the battery body. In the above distribution mode, the clamping mechanism 410 can clamp the input and output connector of the battery, and the tube film pushing mechanism 420 can push the tube film on the other side, so that the battery body is covered in place, which is convenient for pushing the tube film in place.

[0039] In the embodiment, the clamping mechanism 410 includes two positioning clamps 411 and two clamping drivers 412. The two positioning clamps 411 are slidably disposed on the base 100 in the vertical direction. The two positioning clamps 411 are arranged in the vertical direction. A battery clamping position is formed between the two positioning clamps 411. The two clamping drivers 412 are connected to the two positioning clamps 411 in a one-to-one correspondence and can drive the two positioning clamps 411 to move closer to or away from each other. When the two positioning clamps 411 are driven closer to each other by the two clamping drivers 412, the battery can be firmly clamped, and when the two clamping drivers 412 drive the two positioning clamps 411 to move away from each other, the battery on the conveying device 200 can be directly avoided, thereby reducing the risk of friction or collision between the battery and the positioning clamps 411 when the conveying device 200 conveys the battery.

[0040] Specifically, the positioning clamp 411 clamps the input and output connectors of the battery to precisely position the battery. The positioning clamp 411 is a block, and is provided with a slide groove. A slide rail is provided on one side of the clamping driver 412. The slide groove is slidably arranged on the slide rail. The positioning clamp 411 is vertically slidably connected to the clamping driver 412. The clamping driver 412 is connected to the base 100, so that the positioning clamp 411 is indirectly vertically slidably arranged on the base 100. The clamping driver 412 adopts a linear cylinder, and the piston rod is connected to the positioning clamp 411 to drive the positioning clamp 411 to move vertically.

[0041] It is conceivable that the positioning clamp 411 can also be connected to the base 100 vertically movably through the guide column and guide sleeve structure, and the clamping driver 412 can adopt a structure such as an electric cylinder, an oil cylinder or a linear motor to drive the positioning clamp 411 to move vertically to move closer to or away from each other. It is conceivable that the clamping mechanism 410 can also be other structures, for example, the clamping mechanism 410 includes two positioning clamps 411, a gear set and a motor, the positioning clamps 411 are rotatably connected to the base 100, the two positioning clamps 411 are arranged side by side, and the motor drives the two positioning clamps 411 to rotate closer to clamp the battery, or rotate away to release the battery through the gear set; or the clamping mechanism 410 includes two positioning clamps 411, a connecting rod assembly and a clamping driver 412, the two positioning clamps 411 are connected to the base 100 vertically and can move closer to or away from each other, and the clamping driver 412 drives the two positioning clamps 411 to move synchronously through the connecting rod assembly.

[0042] In the embodiment, the conveying direction of the conveying device 200 is from front to back, and the conveying device 200 includes a first conveying line 210, and the first conveying line 210 includes a moving frame 211, a battery bracket 212, a first conveying driver 213 and a first lifting driver 214. The moving frame 211 is movably arranged on the base 100 along the front-to-back direction. The first conveying driver 213 is used to drive the moving frame 211 to move back and forth. The moving frame 211 is arranged with at least two first battery positioning grooves 215 arranged along the front-to-back direction. The first lifting driver 214 can drive the upper side of the battery bracket 212 to rise and fall to above or below the first battery positioning groove 215, so that the battery is separated from or placed in the first battery positioning groove 215. The above structure can make the battery move to different first battery positioning grooves 215 in sequence from the front to the back, so as to realize the conveying of the battery along the conveying device 200. The first battery positioning groove 215 can make the battery automatically positioned each time it is conveyed, so as to facilitate the tube film positioning device 400 to accurately clamp the battery.

[0043] Specifically, when the upper side of the battery holder 212 is lower than the first battery positioning slot 215, the battery is placed in the first battery positioning slot 215. During this period, the first conveying driver 213 can drive the movable frame 211 to move backward to the end of the stroke, and then the first lifting driver 214 drives the battery holder 212 to rise to lift the battery so that the battery is out of the first battery positioning slot 215. Then the first conveying driver 213 can drive the movable frame 211 to move forward and reset to the starting point of the stroke. Then the first lifting driver 214 drives the battery holder 212 to descend to reposition the battery in a different first battery positioning slot 215. The operation is then cyclically performed to gradually convey the battery in the direction from front to back with a better positioning effect.

[0044] Specifically, the moving frame 211 is connected to the base 100 by sliding forward and backward through a slide rail and slider structure, the first conveying driver 213 is a linear cylinder, and the piston rod is connected to the moving frame 211 to drive the moving frame 211 to move forward and backward. The first lifting driver 214 is a linear cylinder, which drives the battery bracket 212 to rise and fall vertically. It is conceivable that in other embodiments, the moving frame 211 can also be movable in the front and rear direction relative to the base 100 through a guide column and guide sleeve structure, the first conveying driver 213 can also be an electric cylinder or a linear motor, and the first lifting driver 214 can also be an electric cylinder or a linear motor.

[0045] In the embodiment, at least two second battery positioning grooves 216 are arranged in the front-to-back direction on the upper side of the battery bracket 212. The second battery positioning grooves 216 are provided, and the battery bracket 212 lifts the battery so that when the battery is separated from the first battery positioning groove 215 of the mobile frame 211, the position can be limited by the second battery positioning grooves 216, thereby preventing the battery from shaking relative to the battery bracket 212 and causing position deviation.

[0046] Specifically, the mobile frame 211 can be provided with two, three or more first battery positioning grooves 215 arranged in the front-to-back direction, and the battery bracket 212 can be provided with two, three or more second battery positioning grooves 216 arranged in the front-to-back direction. Technical personnel in this field can make specific configurations according to actual needs.

[0047] Specifically, the first battery positioning groove 215 and the second battery positioning groove 216 are both adapted to the outer peripheral shape of the battery. When the battery is a cylindrical battery, the first battery positioning groove 215 and the second battery positioning groove 216 are arc grooves.

[0048] In an embodiment, the mobile frame 211 includes two side frames arranged side by side with a left and right interval, and the battery bracket 212 is vertically slidably arranged between the two side frames, so that when the mobile frame 211 holds up the battery, it can hold the middle position of the battery to avoid the risk of the battery falling due to unbalanced weight at both ends.

[0049] In the embodiment, a battery loading device 600 is also included, and the battery loading device 600 includes a second conveyor line 610, a loading push piece 620 and a loading driver 630. The conveying direction of the conveyor 200 is from front to back. The second conveyor line 610 is located on one side of the conveyor 200 along the left-right direction. The loading driver 630 can drive the loading push piece 620 to move left and right to push the batteries on the second conveyor line 610 into the conveyor 200. The film sleeve mechanism 300 is provided with a tube film picking and placing structure 310. The tube film picking and placing structure 310 is located above the conveyor 200. A tube film picking and placing position is formed between the tube film picking and placing structure 310 and the conveyor 200. The loading push piece 620 is opposite to the tube film picking and placing position on the left and right.

[0050] The tubular film pick-up and placement structure 310 grabs the tubular film at the tubular film pick-up and placement position, and then the loading driver 630 can drive the loading pusher 620 to push the battery on the second conveyor line 610 into the conveying device 200, during which the battery is inserted into the tubular film, and then the tubular film pick-up and placement structure 310 releases the tubular film, so that the tubular film and the battery are positioned and placed together on the first battery positioning groove 215 of the mobile frame 211. The battery loading device 600 mentioned above simultaneously sets the tubular film on the periphery of the battery during the process of moving the battery into the conveying device 200, thereby simplifying the production process.

[0051] Specifically, the second conveyor line 610 is a belt conveyor line, the feeding driver 630 is a linear cylinder, and the piston rod is connected to the feeding push piece 620, thereby driving the feeding push piece 620 to move left and right. It is conceivable that the second conveyor line 610 can also be other types of conveyor lines, such as a chain plate conveyor line, a wheel conveyor line, etc., and the feeding driver 630 can also adopt structures such as an electric cylinder or a linear motor, and those skilled in the art can make specific configurations according to actual needs.

[0052] Specifically, the second conveyor line 610 also conveys from front to back. The second conveyor line 610 is provided with a plurality of battery accommodating slots arranged along the conveying direction to facilitate the arrangement, positioning and conveying of batteries.

[0053] In the embodiment, the tube film pick-up and placement structure 310 is provided with a first suction cup, the second conveying line 610 is provided with a second suction cup, the first suction cup and the second suction cup are vertically opposite, and the film sleeve mechanism 300 is provided with a second lifting driver 320, and the second lifting driver 320 is used to drive the tube film pick-up and placement structure 310 to rise and fall. The tube film can be relatively conveniently picked up and placed by means of the suction cup, and the first suction cup and the second suction cup are opposite and can be close to or away from each other, so that the tube film can be pulled apart, making it convenient to place the battery into the tube film.

[0054] Specifically, when the tubular membrane is not stretched, it is a flattened annular membrane. When the tubular membrane needs to be stretched, the second lifting driver 320 drives the first suction cup and the second suction cup to approach each other, and the first suction cup and the second suction cup absorb both sides of the tubular membrane, and then the second lifting driver 320 drives the first suction cup and the second suction cup to move away from each other to stretch the tubular membrane.

[0055] Specifically, the second lifting driver 320 is a cylinder, which is connected to the tube membrane picking and placing structure 310 to drive the tube membrane picking and placing structure 310 to rise and fall. It is conceivable that the second lifting driver 320 can also adopt a structure such as an electric cylinder or a linear motor.

[0056] In the embodiment, a tube film feeding device 700 is also included, and the tube film feeding device 700 is arranged on the machine base 100. The tube film feeding device 700 includes a film strip delivery mechanism 710 and a cutting mechanism 720. The film strip delivery mechanism 710 is used to move the film strip toward the tube film taking and placing position, and the cutting mechanism 720 is arranged between the film sleeve mechanism 300 and the tube film feeding device 700. The cutting mechanism 720 is provided with a film strip cutting knife 721 for cutting the film strip into a tube film. The above structure can cut the film strip into a tube film, and automatically transport it to the tube film taking and placing position, thereby improving the automation degree of the equipment and facilitating continuous production.

[0057] Specifically, two film strip cutting knives 721 are provided and arranged vertically, and the cutting mechanism 720 also includes a cutting driver, which is connected to one of the film strip cutting knives 721 and can drive the film strip cutting knives 721 to approach or move away from the other film strip cutting knives 721, and cut the film strip into a tubular film in a manner similar to scissors. The cutting driver is a cylinder, and the cylinder drives one of the film strip cutting knives 721 to move through a piston rod. It can be understood that the cutting driver can also adopt a structure that outputs linear power such as an electric cylinder, or a motor, and one of the film strip cutting knives 721 is rotatably set on the machine base 100, and the motor drives the film strip cutting knives 721 to rotate, so that the two film strip cutting knives 721 are close to each other to cut the film strip to form a tubular film.

[0058] In the embodiment, the film strip delivery mechanism 710 includes two paired driving rollers 711 and a roller driver 712. A film strip clamping position is formed between the two paired driving rollers 711. At least one driving roller 711 is adjustably arranged on the machine base 100 and can adjust the distance between the two driving rollers 711. The roller driver 712 is used to drive the driving roller 711 to rotate. The roller driver 712 rotates the driving roller 711, clamps and pushes the film strip between the two driving rollers 711 to move toward the tube film taking and placing position, and transports the film strip; and because the distance between the two driving rollers 711 is adjustable, the film strip delivery mechanism 710 can clamp and adapt to film strips of different specifications, and adjust the friction between the driving roller 711 and the film strip, so the use effect is relatively good, and the film strip replacement is relatively convenient.

[0059] Specifically, the roller driver 712 drives one of the driving rollers 711 to rotate. It is conceivable that the roller driver 712 can also drive the two driving rollers 711 to rotate in opposite directions at the same time.

[0060] Specifically, the film strip delivery mechanism 710 also includes a screw and an adjustment frame 713, one end of the adjustment frame 713 is pivoted to the base 100, one of the driving rollers 711 is pivoted to the other end of the adjustment frame 713, and the other driving roller 711 is pivoted to the base 100. The screw is threadedly connected to the base 100 and can push the adjustment frame 713 to rotate relative to the base 100, so that the two driving rollers 711 can be close to or away from each other, and the distance between the two driving rollers 711 can be adjusted. The structure is simple, and the adjustment method is labor-saving and reliable. It is conceivable that the distance between the two driving rollers 711 can be adjusted by other structures. For example, the two driving rollers 711 are respectively pivoted to two sliders, and the two sliders are arranged on the slide rail along a straight line, so that the two driving rollers 711 can be close to or away from each other, and the slider is provided with a threaded through hole, and the screw is threadedly connected to the threaded through hole. When the screw is tightened, the position of the slider is fixed by friction, so that the distance between the two driving rollers 711 can be adjusted. It is understandable that the position of one driving roller 711 can be adjusted relative to the machine base 100 , or the position of both driving rollers 711 can be adjusted relative to the machine base 100 .

[0061] It is conceivable that the film strip delivery mechanism 710 may also be other structures, such as using a belt conveyor line to deliver the film strip toward the tube film pick-up and placement position.

[0062] Specifically, the film strip delivery mechanism 710 is also provided with a storage wheel, the film strip is wound around the storage wheel, the storage wheel is pivotally connected to the machine base 100, the film strip extends from the storage wheel and is pulled out by two driving rollers 711, and when it is sent to the tube film picking and placing position, it is cut by the cutting mechanism 720 to form a tube film.

[0063] In the embodiment, a material unloading and boxing mechanism 800 is also included. The material unloading and boxing mechanism 800 is arranged on the machine base 100. The conveying direction of the conveying device 200 is from front to back. The material unloading and boxing mechanism 800 includes a material receiving box 810, a descending drive 820, a material unloading push piece 830 and a material unloading drive 840. The material receiving box 810 and the material unloading push piece 830 are respectively arranged on the left and right sides of the conveying device 200.
