Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing technology, and in particular to a conveying and guiding structure for the winding process of lithium battery cylindrical shells. Background Technology

[0002] The wound lithium battery cylindrical casing is a special battery casing design primarily used for encapsulating cylindrical lithium batteries. Currently, the material strip needs to be straightened before winding. Straightening ensures that the material strip maintains the correct position and shape during winding, avoiding problems such as bending and curling, thereby improving product quality and consistency. At the same time, straightening the material strip reduces the time spent on pauses and adjustments during winding, increasing production efficiency while reducing material waste and costs.

[0003] A commonly used method for winding lithium battery cylindrical shells involves a lithium battery cylindrical shell winding device. The set material belt conveying mechanism can automatically feed the material, and the set double roller guiding mechanism adopts two wheels to guide the material belt conveying and ensure that the edge line of the wound cylindrical shell is flush and without misalignment.

[0004] Existing strips used for winding lithium battery cylindrical shells are processed through multi-layer winding, resulting in an inevitably thinner thickness. The aforementioned patent uses wedge-shaped guide rings to press and guide the strip. Due to the thinness of the strip, when the edge of the strip contacts the guide ring, friction occurs, easily causing scratches on the strip edge. In severe cases, damage or curling may occur, leading to significant defects in the subsequently produced wound lithium battery cylindrical shells, and in severe cases, even failure to meet standards. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying and guiding structure for the winding process of lithium battery cylindrical shells in order to solve the above-mentioned problems. This improves the problem that the existing conveying and guiding structures used in the winding process of lithium battery cylindrical shells have poor guiding and correction effects on the material strip, which can easily lead to low quality of subsequent finished products.

[0006] The present invention achieves the above-mentioned objective through the following technical solution: a conveying and guiding structure for the winding process of lithium battery cylindrical shells, comprising a frame, a conveying shaft mounted on the inner surface of the frame, a central controller fixedly connected to one end of the frame, and a guiding device mounted on the surface of the frame; the guiding device includes a position detection mechanism mounted on the surface of the frame, a correction mechanism fixedly connected to the frame mounted on the surface of the position detection mechanism, and an auxiliary mechanism fixedly connected to the frame mounted on the surface of the correction mechanism.

[0007] Preferably, the position detection mechanism includes an adjustment component, which is mounted on the surface of the frame. Two guide plates, each sleeved on the surface of the conveyor shaft, are mounted on the surface of the adjustment component. A protective component is fixedly connected to the surface of the guide plate. A glass grating ruler and a grating reading head are installed inside the protective component. The glass grating ruler and the grating reading head are respectively located on the upper and lower sides of the highest point of the conveyor shaft.

[0008] Preferably, the correction mechanism includes a correction shaft, both ends of which extend to the outside of the guide plate. Both ends of the surface of the correction shaft are provided with sliding grooves. The inner wall of the sliding groove is slidably connected to a sliding shaft fixedly connected to the frame. The surface of the correction shaft is slidably connected to a first rotating sleeve. One end of the first rotating sleeve is fixedly connected to a first electric hydraulic cylinder fixedly connected to the frame.

[0009] Preferably, a pressure switch is embedded at each of the opposite ends of the two guide plates, and one end of the pressure switch is flush with the surface of the guide plate.

[0010] Preferably, the adjustment assembly includes a guide rod, which is fixedly connected to the inner surface of the frame. A mounting base is fixedly connected to the bottom of the guide rod. Both ends of the mounting base are rotatably connected to threaded adjustment rods that are rotatably connected to the frame. One end of the threaded adjustment rod extends to the outside of the frame. A threaded seat that is slidably connected to the guide rod is threadedly connected to the surface of the threaded adjustment rod. The guide plate is fixedly connected to the top of the threaded seat.

[0011] Preferably, the surface of the threaded adjusting rod is fitted with two rubber bellows, one of which is fixedly connected between the frame and the threaded seat, and the other is fixedly connected between the mounting base and the threaded seat.

[0012] Preferably, the protective assembly includes a horizontal folding frame, which is fixedly connected to the surface of the guide plate. The glass grating ruler is embedded in the lower surface of the horizontal folding frame. The grating reading head is fixedly connected to one end of the horizontal folding frame. The glass grating ruler and the grating reading head face each other. A transparent protective tube fitted onto the surface of the grating reading head is rotatably connected to one end of the horizontal folding frame. An internal gear ring is fixedly connected to the inner wall of the transparent protective tube. A gear is meshed with the inner side of the internal gear ring. A micro motor is fixedly connected to one end of the gear. A mounting plate is fixedly connected to the bottom of the horizontal folding frame. A cleaning block that contacts the transparent protective tube is adhered to the top of the mounting plate.

[0013] Preferably, a rubber block is bonded between the mounting plate and the cleaning block, and the rubber block is in a compressed state at this time.

[0014] Preferably, the auxiliary mechanism includes two pressure sensors and a mounting bracket. The two pressure sensors are respectively embedded and installed at both ends of the slide shaft. The mounting bracket is fixedly connected to the surface of the frame. A second electric hydraulic cylinder is fixedly connected to the surface of the mounting bracket. A shaft seat is fixedly connected to the top of the second electric hydraulic cylinder. An auxiliary shaft is rotatably connected to the surface of the shaft seat.

[0015] Preferably, a second rotating sleeve is slidably connected to the surface of the auxiliary shaft, and a third electric hydraulic cylinder is fixedly connected to one end of the second rotating sleeve and fixedly connected to the shaft seat.

[0016] Preferably, the inner bottom wall of the bearing seat is fixedly connected with a support frame that is evenly distributed and in contact with the auxiliary shaft, and the cross-sectional shape of the support frame is an inverted U-shape.

[0017] Preferably, the surface of the support frame is rotatably connected to a roller, and the surface of the roller contacts the auxiliary shaft.

[0018] The beneficial effects of this invention are:

[0019] 1. The position detection mechanism can detect the position of both sides of the material strip in a non-contact manner and transmit it to the central controller. At this time, the central controller can accurately calculate whether the position of the material strip has deviated. When the calculation result shows that the material strip has deviated, the central controller uses the correction mechanism to straighten the material strip of the contact part as a whole. Compared with the existing wedge guide ring straightening method, this reduces the probability of the material strip edge being pressed, thereby avoiding scratches on the material strip edge due to straightening. In severe cases, it may even cause damage or curling, so that the material strip entering the subsequent structure remains intact, thereby ensuring the finished product quality of the wound lithium battery cylindrical shell;

[0020] 2. When the correction shaft moves to its limit position, it triggers the corresponding pressure sensor. After receiving the pressure signal, the central controller controls the second electric hydraulic cylinder to lift the material belt on the auxiliary shaft, so that the material belt is suspended above the correction shaft by the auxiliary shaft and the conveyor shaft. At this time, the central controller can quickly reset the correction shaft without stopping the entire device and then resetting the correction shaft, so as to ensure the normal operation efficiency of the device. Furthermore, if the material belt deviates during the process of the auxiliary shaft suspending the material belt above the correction shaft, the central controller can control the third electric hydraulic cylinder to drive the auxiliary shaft to move horizontally through the second rotating sleeve. The auxiliary shaft drives the material belt back to the correct position, further ensuring that the material belt is guided and conveyed correctly.

[0021] 3. During normal operation of the grating reading head, the transparent protective sleeve isolates dust, residue, and other particulate matter that falls onto the grating reading head, keeping it clean. Simultaneously, the micro motor drives the gear to rotate, which in turn drives the internal gear ring to rotate, which in turn drives the transparent protective sleeve to rotate. The transparent protective sleeve then rotates the particulate matter, and during this process, the cleaning block wipes away the particulate matter passing through the transparent protective sleeve, ensuring that the transparent protective sleeve remains clean at all times. This reduces interference with the light signal detected by the grating reading head's glass grating ruler, thereby improving the overall operating accuracy of the position detection mechanism.

[0035] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] In practical implementation: such as Figure 1-12 As shown, a conveying and guiding structure for a lithium battery cylindrical shell winding process includes a frame 1, a conveying shaft 2 mounted on the inner surface of the frame 1, a central controller 3 fixedly connected to one end of the frame 1, and a guiding device 4 mounted on the surface of the frame 1. The guiding device 4 includes a position detection mechanism 41, which is mounted on the surface of the frame 1. A correction mechanism 42 fixedly connected to the frame 1 is mounted on the surface of the position detection mechanism 41, and an auxiliary mechanism 43 fixedly connected to the frame 1 is mounted on the surface of the correction mechanism 42.

[0037] like Figure 3-10As shown, the position detection mechanism 41 includes an adjustment component 411, which is mounted on the surface of the frame 1. Two guide plates 412, each fitted onto the surface of the conveyor shaft 2, are mounted on the surface of the adjustment component 411. A protective component 413 is fixedly connected to the surface of the guide plate 412. A glass grating ruler 414 and a grating reading head 415 are installed inside the protective component 413, respectively positioned on the upper and lower sides of the highest point of the conveyor shaft 2. The correction mechanism 42 includes a correction shaft 421, with both ends extending through the guide plate 412. Slide grooves 422 are formed at both ends of the correction shaft 421. A slide shaft 423, fixedly connected to the frame 1, is slidably connected to the inner wall of the slide grooves 422. A first rotating sleeve 424 is slidably connected to the surface of the correction shaft 421, and a first electric hydraulic cylinder 425, fixedly connected to the frame 1, is fixedly connected to one end of the first rotating sleeve 424. The position detection mechanism 41 can be connected non-contactly... The position of the material strip on both sides is detected by touch and transmitted to the central controller 3. The central controller 3 can then accurately calculate whether the position of the material strip has deviated. When the calculation result shows that the material strip has deviated, the central controller 3 uses the correction mechanism 42 to correct the material strip of the contact part as a whole. Compared with the existing wedge guide ring correction method, this reduces the probability of the material strip edge being pressed, thereby avoiding scratches on the material strip edge due to correction, and even damage or curling of the material strip edge in severe cases. This ensures that the material strip entering the subsequent structure remains intact, thereby ensuring the finished product quality of the wound lithium battery cylindrical shell. Pressure switches 416 are embedded at the opposite ends of the two guide plates 412. One end of the pressure switch 416 is flush with the surface of the guide plate 412. When the edge of the material strip still exceeds the standard range, the material strip will squeeze the pressure switch 416 in the path. The pressure switch 416 pauses the entire device to prevent unqualified material strip from entering the subsequent structure, thereby reducing greater losses later.

[0038] like Figure 4As shown, the adjustment assembly 411 includes a guide rod 4111, which is fixedly connected to the inner surface of the frame 1. A mounting base 4112 is fixedly connected to the bottom of the guide rod 4111. Both ends of the mounting base 4112 are rotatably connected to threaded adjusting rods 4113, which are rotatably connected to the frame 1. One end of the threaded adjusting rod 4113 extends to the outside of the frame 1. A threaded seat 4114, which is slidably connected to the guide rod 4111, is threadedly connected to the surface of the threaded adjusting rod 4113. A guide plate 412 is fixedly connected to the top of the threaded seat 4114. When the operator needs to inspect material strips of different widths, the operator only needs to rotate the threaded adjusting rod 4113 in the corresponding direction, and the threaded adjusting rod 4113 will drive the threaded seat 4114 along the guide rod 4111. The threaded seat 4114 slides on the surface of the threaded rod 4111, causing the guide plate 412 to move in the corresponding direction until the guide plate 412 is adjusted to the corresponding position. Two rubber bellows 4115 are sleeved on the surface of the threaded adjusting rod 4113. One rubber bellows 4115 is fixedly connected between the frame 1 and the threaded seat 4114, and the other rubber bellows 4115 is fixedly connected between the mounting base 4112 and the threaded seat 4114. The rubber bellows 4115 can wrap the exposed threaded part of the threaded adjusting rod 4113 inside, so that the threaded adjusting rod 4113 operates in a relatively clean environment, reducing the resistance of the operator driving the threaded seat 4114 through the threaded adjusting rod 4113.

[0039] like Figure 5 , Figure 6 and Figure 7As shown, the protective assembly 413 includes a horizontal folding frame 4131, which is fixedly connected to the surface of the guide plate 412. A glass grating ruler 414 is embedded in the lower surface of the horizontal folding frame 4131. A grating reading head 415 is fixedly connected to one end of the horizontal folding frame 4131, with the glass grating ruler 414 and the grating reading head 415 facing each other. A transparent protective cylinder 4132, which is sleeved on the surface of the grating reading head 415, is rotatably connected to one end of the horizontal folding frame 4131. An internal gear ring 4133 is fixedly connected to the inner wall of the transparent protective cylinder 4132. Gear 4134 is meshed on the inner side of 33. A micro motor 4135 is fixedly connected to one end of gear 4134. A mounting plate 4136 is fixedly connected to the bottom of the horizontal folding frame 4131. A cleaning block 4137 that contacts the transparent protective cylinder 4132 is adhered to the top of the mounting plate 4136. The starting end of the glass grating ruler 414 faces away from the micro motor 4135. Therefore, it can be seen that the larger the electrical signal detected by the grating reading head 415, the smaller the area of ​​the glass grating ruler 414 blocked by the material tape. This also indicates that the material tape is moving towards the grating reading head 415, which detects a smaller electrical signal. 15 offset; During the normal operation of the grating reading head 415, the transparent protective tube 4132 isolates dust, residue, and other dust contaminants falling onto the grating reading head 415, keeping the grating reading head 415 clean. Simultaneously, the micro motor 4135 drives the gear 4134 to rotate, which in turn drives the internal gear ring 4133 to rotate. The internal gear ring 4133 then drives the transparent protective tube 4132 to rotate, causing the transparent protective tube 4132 to rotate and thus rotate the dust contaminants. During this process, the cleaning block 4137 wipes away the dust contaminants passing through the transparent protective tube 4132. The removal of contaminants keeps the transparent protective cylinder 4132 clean at all times, which reduces interference with the light signal detected by the grating reading head 415 and the glass grating ruler 414, thereby improving the overall operating accuracy of the position detection mechanism 41. A rubber block 4138 is bonded between the mounting plate 4136 and the cleaning block 4137, and the rubber block 4138 is in a compressed state at this time. The rubber block 4138 can increase the contact area and contact pressure between the cleaning block 4137 and the transparent protective cylinder 4132, thereby improving the cleaning effect on the transparent protective cylinder 4132.

[0040] like Figure 10 , Figure 11 and Figure 12As shown, the auxiliary mechanism 43 includes two pressure sensors 431 and a mounting bracket 432. The two pressure sensors 431 are respectively embedded at both ends of the slide shaft 423. The mounting bracket 432 is fixedly connected to the surface of the frame 1. A second electric hydraulic cylinder 433 is fixedly connected to the surface of the mounting bracket 432. A bearing seat 434 is fixedly connected to the top of the second electric hydraulic cylinder 433. An auxiliary shaft 435 is rotatably connected to the surface of the bearing seat 434. When the correction shaft 421 moves to its limit position, the correction shaft 421 just squeezes the corresponding pressure sensor 431 through the slide groove 422. The pressure sensor 431 transmits the pressure signal to the central controller 3. The central controller 3 then... A preset command controls the second electric hydraulic cylinder 433 to raise the shaft seat 434, which in turn raises the auxiliary shaft 435 until the auxiliary shaft 435 lifts the material belt above the alignment shaft 421. At this point, the auxiliary shaft 435, in conjunction with the conveyor shaft 2, suspends the material belt above the alignment shaft 421. The central controller 3 then controls the first electric hydraulic cylinder 425 to reset according to the preset command. The first electric hydraulic cylinder 425, through the first rotating sleeve 424, drives the alignment shaft 421 to reset. Finally, the central controller 3 retracts the second electric hydraulic cylinder 433 according to the preset command, returning the shaft seat 434 and auxiliary shaft 435 to their original positions. At this point, the material belt is once again draped over the alignment shaft. On 421, the first electric hydraulic cylinder 425 can still drive the correction shaft 421 to normally correct and guide the material belt through the first rotating sleeve 424. During the above process, the operator does not need to stop the entire device and then reset the correction shaft 421 to ensure the normal operation efficiency of the device. The surface of the auxiliary shaft 435 is slidably connected to the second rotating sleeve 436. One end of the second rotating sleeve 436 is fixedly connected to the third electric hydraulic cylinder 437, which is fixedly connected to the shaft seat 434. During the process of the auxiliary shaft 435 suspending the material belt above the correction shaft 421, if the material belt deviates at this time, the central controller 3 can control the third electric hydraulic cylinder 437 to drive the auxiliary shaft 435 through the second rotating sleeve 436. Horizontal movement causes the auxiliary shaft 435 to return the material belt to its upright position, further ensuring the belt is guided and conveyed correctly. The inner bottom wall of the shaft seat 434 is fixedly connected to evenly distributed support frames 438, all in contact with the auxiliary shaft 435. The cross-sectional shape of the support frames 438 is inverted U-shaped. The support frames 438 make the auxiliary shaft 435 more rigid and straight, reducing the probability of bending. Rollers 439 are rotatably connected to the surface of the support frames 438, and the surface of the rollers 439 contacts the auxiliary shaft 435. This reduces the pressure between the auxiliary shaft 435 and the support frames 438, allowing the auxiliary shaft 435 to rotate along with the material belt, thereby reducing friction between the auxiliary shaft 435 and the material belt.

[0041] When using this invention, the operator first passes the material strip through the glass grating ruler 414 and the grating reading head 415, and then places the material strip on the upper surface of the correction shaft 421 and the conveying shaft 2 at the same time. Then the entire lithium battery cylindrical shell winding system can be started to operate normally.

[0042] During the process of the conveyor belt passing between the glass grating ruler 414 and the grating reading head 415, the grating reading head 415 reads the light signal emitted by the glass grating ruler 414 that is not blocked by the conveyor belt, converts the light signal into an electrical signal, and then transmits it to the central controller 3. The central controller 3 converts the electrical signals transmitted by the two grating reading heads 415 into corresponding digital signals and compares the two digital signals. Therefore, if one digital signal is less than the other digital signal, it indicates that the conveyor belt is shifted towards the grating reading head 415 that detects the smaller electrical signal. At the same time, the central controller 3 controls the first electric hydraulic cylinder 425 to move towards the grating reading head 415 that detects the smaller electrical signal according to a preset program. The small electrical signal grating reading head 415 moves in the opposite direction a specified distance, the first electric hydraulic cylinder 425 drives the first rotating sleeve 424 to move horizontally a specified distance, the first rotating sleeve 424 drives the correction shaft 421 to move horizontally a specified distance, the correction shaft 421 drives the material strip of the contact part to move horizontally a specified distance, and corrects and guides the material strip. Compared with the existing wedge guide ring correction method, this reduces the probability of the material strip edge being pressed, thereby avoiding scratches on the material strip edge due to correction, and in severe cases, even damage or curling. This ensures that the material strip entering the subsequent structure remains intact, thereby ensuring the finished product quality of the wound lithium battery cylindrical shell.

[0043] It should be noted that the central controller 3, glass grating ruler 414, grating reading head 415, pressure switch 416, first electric hydraulic cylinder 425, pressure sensor 431, second electric hydraulic cylinder 433, and third electric hydraulic cylinder 437 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the power supply of the central controller 3, glass grating ruler 414, grating reading head 415, pressure switch 416, first electric hydraulic cylinder 425, pressure sensor 431, second electric hydraulic cylinder 433, and third electric hydraulic cylinder 437 can be powered by the built-in power supply or by the mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
