Description

Technical Field

[0001] This invention relates to the field of capacitor production equipment technology, and in particular to a sticker module. Background Technology

[0002] In the automated winding production process of aluminum electrolytic capacitors, the core process of winding the capacitor core is to simultaneously wind the positive electrode foil, negative electrode foil, and separator film according to a preset stacking order, starting from the beginning of the roll, to ultimately form the capacitor core. Among these processes, the isolation treatment at the beginning of the winding of the positive and negative electrode foil strips is a critical step that determines the voltage withstand capability, insulation performance, and leakage current qualification rate of the finished capacitor. Multiple layers of insulating separator paper must be pre-attached to the starting ends of the positive and negative electrode foil strips to insulate and isolate the beginning ends of the positive and negative electrode foils from each other, while also isolating the burrs on the edges of the foil materials. This prevents direct contact between the positive and negative electrodes during the initial stage of winding, avoiding short circuits, breakdowns, and leakage current, and preventing the finished capacitor from failing and being scrapped.

[0003] Existing membrane sticker modules generally adopt a segmented process flow of feeding-traction-cutting-sticking, but their structural layout and operation logic have inherent defects: Existing labeling equipment typically places the cutting unit downstream of the traction clamp on the discharge side. After the traction unit completely pulls out the diaphragm strip, it sequentially performs cutting, offline transfer, and labeling actions. This structure has the following technical drawbacks: the cutting and labeling processes are separated; after the diaphragm strip is cut into individual diaphragms, an additional transfer mechanism is needed to move the diaphragm from the cutting station to the labeling station; the overall equipment occupies a large space and has a long transmission chain; the diaphragm transfer process is prone to misalignment, wrinkles, and damage; the labeling positioning accuracy is poor, and the defect rate is high. To address these issues, a reasonably laid-out labeling device is needed to facilitate production. Summary of the Invention

[0004] In order to overcome the problems of unreasonable layout of sticker-making devices in the existing technology, resulting in large equipment space occupation and long transmission chains, the purpose of this invention is to provide a sticker-making module that reduces space occupation, has a reasonable layout, reduces the diaphragm transfer and conveying process, and improves the pass rate.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A sticker module includes a feeding unit, a traction unit, a cutting unit, and a sticker unit; The feeding unit is used to supply diaphragm rolls to the outside; The traction unit is located downstream of the feeding unit. The traction unit includes a slide drive source, a linear slide, and a chuck. The chuck is located on the linear slide. The slide drive source drives the linear slide to reciprocate. The chuck is used to hold the end of the diaphragm strip supplied by the feeding unit. The cutting unit is located below the traction unit and close to the feeding unit. The cutting unit is used to cut the diaphragm strip pulled out by the traction unit to obtain a single sheet of diaphragm paper. The sticker unit is located below the traction unit and between the cutting unit and the clamp. The sticker unit attaches a single piece of diaphragm to the target workpiece.

[0006] Furthermore, the traction unit also includes a gripper control component, which includes a second drive source, a pressure rod, and a gripper opening and closing drive component. The output end of the second drive source is connected to the pressure rod for driving the gripper opening and closing drive component to reciprocate vertically. The pressure rod abuts against the gripper opening and closing drive component, and the gripper opening and closing drive component is connected to the chuck. Under the downward pressure of the pressure rod, the gripper opening and closing drive component drives the chuck to open and close, thereby achieving the clamping and releasing of the end of the diaphragm strip.

[0007] Furthermore, the clamping surface of the chuck is provided with an anti-slip buffer layer to prevent damage to the diaphragm roll during clamping.

[0008] Furthermore, the feeding unit includes a material carrier tray, a tension wheel, and a guide roller arranged in sequence. The material carrier tray carries the diaphragm roll from the outside. The single-layer diaphragm is pulled out by the traction unit in sequence through the tension wheel and the guide roller. The movement direction of the linear slide is perpendicular to the line connecting the tension wheel and the guide roller.

[0009] Furthermore, the feeding unit also includes a stop block and a first driving source, the first driving source driving the stop block to move toward or away from the guide roller, so that the single-layer diaphragm strip slides between the guide roller and the stop block.

[0010] Furthermore, the cutting unit includes a third drive source, a transmission link, a first gear, a second gear, a first cutter, and a second cutter. The output end of the third drive source is connected to the transmission link. The transmission link is hinged to the first gear. The first gear meshes with the second gear. The first cutter is fixed to the first gear, and the second cutter is fixed to the second gear. The third drive source drives the transmission link to move, causing the first gear and the second gear to rotate synchronously in opposite directions, so that the first cutter and the second cutter can achieve synchronous opening and closing actions.

[0011] Furthermore, the sticker unit includes an auxiliary component, a fourth driving source, and a pressing block. The fourth driving source drives the pressing block to move linearly back and forth in a direction closer to or farther from the auxiliary component, so as to adhere / press the single sheet of diaphragm paper to the target to be pasted.

[0012] Furthermore, the auxiliary component includes a bracket and a roller rotatably connected to the bracket, and the pressure block cooperates with the roller to stick the external sticker to the target.

[0013] The beneficial effects of this invention are as follows: By setting specific positions and structural coordination of the feeding unit, traction unit, cutting unit, and sticker unit, the sticker unit is positioned directly below the traction unit and between the cutting unit and the clamp. The overall module structure is compact and has high space utilization. The traction unit adopts a linear slide table for rigid traction feeding, ensuring high positioning accuracy of the diaphragm strip without slippage or offset. The cutting, clamping, and sticker processes are continuously connected without idle strokes, resulting in high production efficiency. At the same time, the sticker does not require secondary transfer, ensuring stable and reliable sticker application accuracy. The modular design of the equipment makes disassembly and maintenance convenient, effectively solving the technical problems of poor accuracy and low efficiency of existing equipment.

Detailed Implementation

[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0017] Please see Figures 1 to 6 The present invention provides a sticker module, comprising a feeding unit 1, a traction unit 2, a cutting unit 3, and a sticker unit 4. The feeding unit 1 is used to supply diaphragm rolls to the outside; The traction unit 2 is located downstream of the feeding unit 1. The traction unit 2 includes a slide drive source 21, a linear slide 22, and a clamp 23. The clamp 23 is located on the linear slide 22. The slide drive source 21 drives the linear slide 22 to move back and forth. The clamp 23 is used to hold the end of the diaphragm strip supplied by the feeding unit 1. The cutting unit 3 is located on the side below the traction unit 2 and close to the feeding unit 1. The cutting unit 3 is used to cut the diaphragm strip pulled out by the traction unit 2 to obtain a single sheet of diaphragm paper. The sticker unit 4 is located below the traction unit 2 and between the cutting unit 3 and the clamp 23. The sticker unit 4 attaches a single sheet of diaphragm paper to the target workpiece.

[0018] Specifically, in this embodiment, the feeding unit 1, traction unit 2, cutting unit 3 and sticker unit 4 work together to automate the feeding, traction, cutting and sticker application of the diaphragm paper. The traction unit 2 includes a first mounting plate, a slide drive source 21, a linear slide 22 and a clamp 23. The slide drive source 21 is preferably a stepper motor, which is fixedly mounted on the first mounting plate. The linear slide 22 is slidably mounted on the first mounting plate and is connected to the slide drive source 21. The clamp 23 is fixed below the linear slide 22. The cutting unit 3 is arranged close to the outlet of the feeding unit 1 and is located on the diaphragm material conveying path between the feeding unit 1 and the traction unit 2. When the diaphragm material is pulled to the preset cutting position by the traction unit 2, the cutting unit 3 is activated to cut the diaphragm material, thereby cutting the continuous diaphragm material into individual diaphragm paper pieces. The sticker unit 4 is located directly below the traction unit 2 and in the vertical space between the cutting unit 3 and the clamp 23. It is used to receive the cut single sheet of diaphragm paper and attach the single sheet of diaphragm paper to the surface of the target workpiece through precise alignment.

[0019] By setting specific positions and structural coordination of the feeding unit 1, traction unit 2, cutting unit 3, and sticker unit 4, the sticker unit 4 is positioned directly below the traction unit 2 and between the cutting unit 3 and the clamp 23. The overall module structure is compact and has high space utilization. The traction unit 2 adopts a linear slide table for rigid traction feeding, which ensures high positioning accuracy of the diaphragm strip and prevents slippage or offset. The cutting, clamping, and sticker processes are continuously connected without idle strokes, resulting in high production efficiency. At the same time, the sticker does not require secondary transfer, and the sticker application accuracy is stable and reliable. The modular design of the equipment makes disassembly and maintenance convenient, effectively solving the technical problems of poor accuracy and low efficiency of existing equipment.

[0020] The traction unit 2 further includes a gripper control component 24, which includes a second drive source 241, a pressure rod 242, and a gripper opening and closing drive component 243. The output end of the second drive source 241 is connected to the pressure rod 242 to drive the gripper opening and closing drive component 243 to reciprocate vertically. The pressure rod 242 abuts against the gripper opening and closing drive component 243, and the gripper opening and closing drive component 243 is connected to the chuck 23. Under the downward pressure of the pressure rod 242, the gripper opening and closing drive component 243 drives the chuck 23 to open and close, thereby clamping and releasing the end of the diaphragm strip. The second drive source 241 is preferably a miniature pneumatic cylinder or a small servo motor. The first mounting plate of the traction unit 2 is fixedly installed as the power output source for the opening and closing of the gripper. Its output end is connected to the pressure rod 242 for transmission, and is used to output the vertical driving force to drive the pressure rod 242 to perform reciprocating lifting and lowering motion. The lower end of the pressure rod 242 is in contact with the upper force-bearing end of the gripper opening and closing drive member 243. Its function is to transmit the power of the second driving source 241 and apply a vertical downward pressing force to the gripper opening and closing drive member 243. The gripper opening and closing drive member 243 is a lever-type transmission component. Its middle part is hinged to the preset mounting position of the chuck 23 through the hinge shaft to form a fulcrum. Under the downward driving of the pressure rod 242, it rotates around the hinge shaft, thereby driving the chuck 23 to move synchronously and realize the opening and closing control.

[0021] The clamping surface of the chuck 23 is provided with an anti-slip buffer layer to avoid damage to the diaphragm strip during clamping. Different anti-slip buffer layers are configured according to different materials of the diaphragm strip to effectively protect the diaphragm strip.

[0022] Please see Figure 7The feeding unit 1 includes a material tray 11, a tension wheel 12, and a guide roller 13 arranged in sequence. The material tray 11 carries the diaphragm strip roll from the outside. The single-layer strip is pulled out by the traction unit 2 through the tension wheel 12 and the guide roller 13 in sequence. The tension wheel 12 is set on the discharge side of the material tray 11 and is used to tension and adjust the tension of the discharged strip. The guide roller 13 is set on the discharge side of the tension wheel 12 and is used to guide and limit the conveying of the diaphragm strip. The movement direction of the linear slide 22 is perpendicular to the line connecting the tension wheel 12 and the guide roller 13, forming a staggered feeding layout, which effectively reduces the vibration and path interference of the conveying strip.

[0023] The feeding unit 1 further includes a stop block 14 and a first drive source 15. The first drive source 15 drives the stop block 14 to move towards or away from the guide roller 13, so that the single-layer diaphragm strip slides between the guide roller 13 and the stop block 14. Preferably, the stop block 14 is located on the side of the guide roller 13. The first drive source 15 is a linear drive cylinder. The power output end of the first drive source 15 is fixedly connected to the stop block 14. The first drive source 15 can drive the stop block 14 to slide linearly back and forth towards or away from the guide roller 13. When the stop block 14 moves towards the guide roller 13, the gap between the stop block 14 and the guide roller 13 is reduced, and the single-layer strip passing between them is squeezed, limited, and corrected. When the stop block 14 moves away from the guide roller 13, the gap between the stop block 14 and the guide roller 13 is increased, and the squeezing constraint on the diaphragm strip is released, so that the diaphragm strip can be conveyed smoothly and freely.

[0024] Please see Figure 8 The cutting unit 3 includes a second mounting plate, a third drive source 31, a transmission link 32, a first gear 33, a second gear 34, a first cutter 35, and a second cutter 36. The cutting unit 3 is used to perform point-to-point cutting of the single-layer diaphragm strip conveyed by the feeding unit 1. The second mounting plate is located directly below the first mounting plate. The third drive source 31 is a linear drive cylinder mounted on the second mounting plate. The output end of the third drive source 31 is connected to the transmission link 32, and the transmission link 32 is hinged to the first gear 33. A crank-connecting rod transmission structure is formed, in which the first gear 33 and the second gear 34 are arranged side by side and their tooth surfaces mesh with each other to achieve meshing reverse transmission. The first cutter 35 is fixed to the first gear 33, and the second cutter 36 is fixed to the second gear 34. The third drive source 31 drives the transmission connecting rod 32 to move, causing the first gear 33 and the second gear 34 to rotate synchronously in opposite directions, so that the first cutter 35 and the second cutter 36 synchronously close towards each other and open in opposite directions, realizing a stable synchronous opening and closing cutting action, and accurately cutting the single-layer material belt that has been conveyed.

[0025] Please see Figure 9The sticker unit 4 includes an auxiliary component 41, a fourth drive source 42, and a pressing block 43. The fourth drive source 42 drives the pressing block 43 to move linearly back and forth in the direction of approaching or moving away from the auxiliary component 41, fixing the external diaphragm tape to the target to be pasted. The auxiliary component 41 serves as a support reference for sticker application. The fourth drive source 42 is a linear drive cylinder (or electric push rod), whose power output end is fixedly and transmissionally connected to the pressing block 43, providing power for the reciprocating motion of the pressing block 43. After the external target to be pasted is transported to the application position of the sticker unit 4, the fourth drive source 42 drives the pressing block 43 to move towards the auxiliary component 41. The pressing block 43 and the auxiliary component 41 cooperate to clamp the sticker, completing the positioning and fixing of the sticker.

[0026] The auxiliary component 41 includes a bracket 411 and a roller 412 rotatably connected to the bracket 411. The roller 412 is rotatably connected to the bracket 411 via a rotating shaft and can rotate freely around its own axis. After the sticker is initially applied, the fourth drive source 42 maintains a slight holding force, or cooperates with the conveying action of the equipment, so that the roller 412 of the auxiliary component 41 rolls along the surface of the diaphragm material belt to roll the sticker. Through the rolling pressure of the roller 412, the air between the sticker and the target surface is effectively discharged, ensuring that the sticker and the target surface are tightly adhered without air bubbles, thus improving the application quality.

[0027] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
