Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to a device for applying adhesive paper to capacitor electrode sheets. Background Technology

[0002] The inner core of the capacitor is formed by winding electrode sheets. Before winding, conductive foil strips need to be cold-welded onto aluminum foil on the electrode sheets. Then, high-temperature adhesive tape is pasted on the conductive foil strips. That is, adhesive tape is pasted on the upper surface of the conductive foil strips, the lower side of the corresponding positions of the electrode sheets, and the lower surface of the protruding parts of the conductive foil strips. The adhesive tape has the following functions: first, to prevent short circuits of the electrodes; and second, to prevent the conductive foil strips from shifting or falling off.

[0003] Currently, when applying adhesive tape, a roll of tape is fed out. The tape is first applied to the guide strip, then cut with a cutter, and then waits for the next guide strip to be used. However, when the cutter cuts the tape, the tape may stick to the cutter. When the cutter moves downwards, it pulls the tape downwards as well, causing it to droop. This may result in the tape not being properly fed to the top of the guide strip for application on the next feed, producing defective products. Utility Model Content

[0004] The main purpose of this invention is to provide a device for applying adhesive paper to capacitor electrode sheets, which aims to solve the technical problems in the prior art where the adhesive paper may stick to the cutter or sag and fail to adhere properly to the guide foil strip when cutting the adhesive paper.

[0005] To achieve the above objectives, this utility model proposes a device for applying adhesive paper to capacitor electrode sheets, comprising: A paper feeding assembly includes a mounting base, a slide rail extending in a left-right direction is fixedly connected to the upper side of the mounting base, a slide block is slidably connected to the upper side of the slide rail, the slide block can slide left and right along the slide rail, and the slide block is provided with a paper feeding channel for adhesive paper to pass through. A paper clamping assembly is located on the right side of the paper feeding assembly. The paper clamping assembly includes a support plate, a pressure plate, and a clamping block. The support plate is relatively fixed, the pressure plate is located on the left side of the clamping block, and the pressure plate and the clamping block are located above the support plate. An electrode sheet can pass between the upper side of the support plate and the pressure plate and the clamping block. The pressure plate and the clamping block can move downward to clamp the electrode sheet and the adhesive paper or move upward away from the support plate, respectively. When the pressure plate and the clamping block move away from the support plate, the slide can pass between the pressure plate and the support plate. A cutting assembly includes a cutter that is movable in the vertical direction. The cutter is located on the left side of the paper clamping assembly and is fixed relative to the paper clamping assembly in the horizontal direction. When the cutter moves downward, it can move to the lower side of the upper side of the support plate. When the slide moves to the left, it can move to the left side of the cutter. An air blowing assembly includes an air blowing channel located at least to the left of the cutter when the cutter cuts the adhesive paper. The air blowing channel is located below the paper feeding channel and is capable of blowing airflow to the right towards the adhesive paper.

[0006] The electrode sheet and guide foil strip to be covered with adhesive tape are conveyed in the front-to-back direction to the upper side of the support plate and the cutter. The slide moves the adhesive tape to the right, passing over the upper side of the electrode sheet. Then, the clamping block moves downward towards the support plate, clamping the right end of the adhesive tape and pressing it onto the guide foil strip. Then, the slide moves to the left to the left side of the cutter. Because the right end of the adhesive tape is pressed down by the clamping block, more adhesive tape is exposed and adhered to the guide foil strip and the electrode sheet. The pressure plate presses down to stick the adhesive tape onto the guide foil strip. Then, the cutter moves upward to cut the adhesive tape. The adhesive tape is now adhered to the guide foil strip and the electrode sheet. The new end of the adhesive tape exposed on the right side of the slide is on the upper right side of the air blowing channel. The air blowing channel blows air to the right towards the adhesive tape, blowing the end of the adhesive tape upward, thus separating the adhesive tape from the cutter. This prevents the adhesive tape from sticking to the cutter and drooping down with it, affecting the next adhesion and improving the success rate of the adhesive tape being properly adhered to the guide foil strip.

[0007] Preferably, the air blowing assembly includes an air blowing pipe, the air blowing channel is located inside the air blowing pipe, the air blowing pipe is fixedly connected to the mounting base, the air blowing pipe is located on the left side of the cutter, and the air blowing pipe is located on the lower side of the slide.

[0008] The air blowing pipe and air blowing channel are fixed on the left side of the cutter, allowing air to be blown during cutting.

[0009] Preferably, the air blowing channel is located inside the slide, and the slide has an air inlet that communicates with the air blowing channel.

[0010] The air blowing channel is located inside the slide and can move with the slide. In addition to blowing air during cutting, it can also keep blowing air when the slide moves to the right and moves the adhesive tape, keeping the adhesive tape protruding from the right end of the paper feeding channel and preventing it from drooping, thus improving the success rate of pasting.

[0011] Preferably, the air blowing assembly further includes an air blowing switch, which is matched with the air blowing channel and can control whether the air blowing channel blows air.

[0012] Preferably, the air blowing assembly further includes an air volume regulating valve, which is matched with the air blowing channel and can adjust the air flow rate. The operator can adjust the air flow rate via the air volume regulating valve according to the blowing effect on the adhesive paper, allowing for more flexible control.

[0013] Preferably, the cutter includes a blade body and a tooth, the tooth being located on the upper side of the blade body, and the number of the tooth is one, the tooth being conical. Having only one tooth ensures a clean cut, preventing adhesive paper fragments from forming during cutting and facilitating cleanup.

[0014] Preferably, the cutting assembly further includes a cutting drive mechanism, which is fixed relative to the mounting base. A mounting block is fixedly connected to the moving end of the cutting drive mechanism, and the cutter is fixedly connected to the mounting block. The cutting drive mechanism can drive the cutter to move up and down. By setting the cutting drive mechanism, the cutter can be quickly driven to cut the adhesive paper, thereby improving the adhesive cutting efficiency.

[0015] Preferably, the cutter includes a blade body and blade teeth. The blade body includes a mounting portion and a connecting portion. The connecting portion is located on the upper side of the mounting portion, and the blade teeth are located on the upper side of the connecting portion. The mounting portion is fixedly connected to the mounting block. The mounting portion and the mounting block are located on the front or rear side of the slide rail, and the connecting portion is located on the upper side of the slide rail.

[0016] The blade mounting part is fixedly mounted on the mounting block, which makes the blade stable and ensures that the cutter can move smoothly during the cutting process. The notch formed by the connecting part and the mounting part allows the slide rail to pass through, which can prevent the cutter from colliding with the slide rail when moving up and down, ensuring that the cutting process is stable and reliable and the structure is compact.

[0024] like Figures 1 to 6 As shown, an adhesive tape applicator for capacitor electrode sheets includes a paper feeding assembly, a paper clamping assembly, a cutting assembly, and an air blowing assembly.

[0025] The paper feeding assembly includes a mounting base 11. A slide rail 13 extending in a left-right direction is fixedly connected to the upper side of the mounting base 11. A slide block 12 is slidably connected to the upper side of the slide rail 13. The slide block 12 can slide left and right along the slide rail 13. The slide block 12 has a paper feeding channel 121 through which adhesive paper 52 passes. The adhesive paper 52 passes through the paper feeding channel 121 and extends out of the right end of the slide block 12. When the slide block 12 moves to the right, the adhesive paper 52 will move to the right synchronously. The mounting base 11 is also provided with a paper feeding drive mechanism, which can drive the slide block 12 to move left and right. The paper feeding drive mechanism can be a cylinder or other motor drive mechanism.

[0026] The paper clamping assembly is located on the right side of the paper feeding assembly. The paper clamping assembly includes a support plate 21, a pressure plate 22, and a clamping block 23. The support plate 21 is relatively fixed, and the pressure plate 22 is located to the left of the clamping block 23. The pressure plate 22 and the clamping block 23 are located above the support plate 21. An electrode plate 51 can pass between the upper side of the support plate 21 and the pressure plate 22 and clamping block 23. The pressure plate 22 and clamping block 23 can move downwards to clamp the electrode plate 51 and the adhesive paper 52, or move upwards away from the support plate 21, respectively. The slide block 12 can pass between the pressure plate 22 and the support plate 21 when the pressure plate 22 and clamping block 23 move away from the support plate 21. The paper clamping assembly also includes a paper pressing drive mechanism and a paper clamping drive mechanism. The paper pressing drive mechanism can drive the pressure plate 22 to move up and down, and the paper clamping drive mechanism can drive the clamping block 23 to move up and down. The paper pressing drive mechanism and the paper clamping drive mechanism can be driven by a cylinder or other motor-driven mechanism.

[0027] The cutting assembly includes a cutter 31, which can move in the vertical direction. The cutter 31 is located on the left side of the paper clamping assembly and is fixed relative to the paper clamping assembly in the horizontal direction. When the cutter 31 moves downward, it can move to the lower side of the upper side of the support plate 21. When the slide 12 moves to the left, it can move to the left side of the cutter 31.

[0028] The air blowing assembly includes an air blowing channel 41, which is located at least on the left side of the cutter 31 when the cutter 31 cuts the adhesive paper 52. The air blowing channel 41 is located below the paper feeding channel 121 and can blow airflow to the right towards the adhesive paper 52.

[0029] The electrode sheet 51 and the guide foil strip to be applied with adhesive tape 52 are conveyed along the front-back direction to the upper side of the support plate 21 and the cutter 31, as shown in the figure. Figure 1Then, the slide block 12 moves the adhesive tape 52 to the right, passing above the electrode plate 51; then, the clamping block 23 moves downward towards the support plate 21, clamping the right end of the adhesive tape 52 and pressing it onto the guide foil strip, as shown in the figure. Figure 2 Then, the slide block 12 moves to the left to the left side of the cutter 31. Because the right end of the adhesive tape 52 is pressed down by the clamping block 23, more of the adhesive tape 52 is exposed and adhered to the conductive foil strip and electrode sheet 51. The pressure plate 22 presses down to stick the adhesive tape 52 to the conductive foil strip. Then, the cutter 31 moves upward to cut, and the cutter 31 cuts the adhesive tape 52. (Refer to...) Figure 3 After the adhesive tape 52 is pasted on the guide foil and electrode sheet 51, the new end of the adhesive tape 52 is exposed on the right side of the slide 12 at the upper right side of the air blowing channel 41. The air blowing channel 41 blows air to the right and blows the end of the adhesive tape 52 upward, thereby separating the adhesive tape 52 from the cutter 31. This prevents the adhesive tape 52 from sticking to the cutter 31 and falling down with the cutter 31, which would affect the next pasting and improve the success rate of pasting the adhesive tape 52 on the guide foil.

[0030] The air blowing channel 41 can have at least the following two implementations: Example 1: Refer to Figures 1 to 4 The air blowing assembly includes an air blowing pipe 42, an air blowing channel 41 located inside the air blowing pipe 42, the air blowing pipe 42 being fixedly connected to the mounting base 11, the air blowing pipe 42 being located on the left side of the cutter 31, and the air blowing pipe 42 being located on the lower side of the slide 12.

[0031] The air blowing pipe 42 and air blowing channel 41 are fixed on the left side of the cutter 31, and air can be blown during cutting.

[0032] Example 2: Refer to Figure 6 The air blowing channel 41 is located inside the slide 12, and the slide 12 is provided with an air inlet, which is connected to the air blowing channel 41.

[0033] An air blowing channel 41 is located inside the slide 12 and can move with the slide 12. This allows for air blowing not only during cutting but also when the slide 12 moves to the right, keeping the adhesive tape 52 protruding from the right end of the paper feeding channel 121 and preventing it from sagging, thus improving the success rate of pasting. Specifically, the air blowing channel 41 can be formed by assembling multiple parts on the slide 12. An air inlet can be connected to an air pipe, which can bend and deform as the slide 12 moves.

[0034] In some specific embodiments, the air blowing assembly further includes an air blowing switch, which is matched with the air blowing channel 41 and can control whether the air blowing channel 41 blows air. The air blowing switch may be a solenoid valve.

[0035] In some specific embodiments, the air blowing assembly also includes an air volume regulating valve, which is matched with the air blowing channel 41 and can adjust the air flow rate. The operator can adjust the air flow rate through the air volume regulating valve according to the blowing effect on the adhesive paper 52, allowing for more flexible control. The air volume regulating valve can be a throttle valve.

[0036] In some specific embodiments, reference is made to Figure 5 The cutter 31 includes a blade body 311 and a tooth 312. The tooth 312 is located on the upper side of the blade body 311, and there is only one tooth 312. The tooth 312 is conical. Most cutters 31 in the prior art include multiple small teeth. When cutting adhesive tape 52 through multiple small teeth, paper scraps easily stick to the cutter 31, making them difficult to clean. This design uses only one tooth 312, resulting in a smooth cut from the cutter 31, preventing the adhesive tape 52 from breaking during cutting, and facilitating cleaning.

[0037] In some specific embodiments, the cutting assembly further includes a cutting drive mechanism 32, which is fixed relative to the mounting base 11. A mounting block 33 is fixedly connected to the moving end of the cutting drive mechanism 32, and the cutter 31 is fixedly connected to the mounting block 33. The cutting drive mechanism 32 can drive the cutter 31 to move up and down. By setting the cutting drive mechanism 32, the cutter 31 can be quickly driven to cut the adhesive paper 52, thereby improving the cutting efficiency. The cutting drive mechanism 32 can be a cylinder, with the piston rod of the cylinder being the moving end of the cutting drive mechanism 32, or the cutting drive mechanism 32 can be a lead screw mechanism, etc.

[0038] Furthermore, the cutter 31 includes a blade body 311 and a cutting tooth 312. The blade body 311 includes a mounting part 3111 and a connecting part 3112. The connecting part 3112 is located on the upper side of the mounting part 3111, and the cutting tooth 312 is located on the upper side of the connecting part 3112. The mounting part 3111 is fixedly connected to the mounting block 33. The mounting part 3111 and the mounting block 33 are located on the front or rear side of the slide rail 13, and the connecting part 3112 is located on the upper side of the slide rail 13.

[0039] The mounting part 3111 of the blade body 311 is fixedly mounted on the mounting block 33, which makes the blade body 311 stable and ensures that the cutter 31 can move smoothly during the cutting process. The notch formed by the inverted L-shape of the connecting part 3112 and the mounting part 3111 allows the slide rail 13 to pass through, which can prevent the cutter 31 from colliding with the slide rail 13 when it moves up and down, ensuring that the cutting process of the cutter 31 is stable and reliable and the structure is compact.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
