[0032] The features and exemplary embodiments of each aspect of the present application will be described in detail below. In the following detailed description, many specific details are presented to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application. In the drawings and the following description, at least some of the well-known structures and technologies are not shown to avoid unnecessary obscurity to the present application; and, for clarity, the dimensions of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.
[0033] In the description of the present application, it should be noted that unless otherwise specified, the meaning of "a plurality" is two or more; the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0034] The orientation words appearing in the following description are all the directions shown in the figures and do not specifically limit the structure of the embodiments of the present application. In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0035] In the related art, generally, manual operation is performed on both ends of the strip to perform the film threading operation. After the film threading operation is completed, the strip can be moved into the tensile machine for stretching, or the strip can be moved into the oven for baking. However, the accuracy of manual film threading is low, which will have an adverse impact on the film surface quality of the strip. Moreover, manual film threading may pose a great safety hazard to the operator. In view of this, the present application provides a transmission device and a strip processing device.
[0036] To better understand the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0037] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic diagram of a transmission device provided by an embodiment of the first aspect of the present application, Figure 2 and which is a schematic structural diagram of a conveying mechanism provided by an embodiment of the first aspect of the present application.
[0038] An embodiment of the first aspect of the present application provides a transmission device 100 for transmitting a strip. The transmission device 100 includes: a clamping mechanism 1 and a conveying mechanism 2. The clamping mechanism 1 includes two clamping components 11 arranged at intervals. The clamping component 11 includes a plurality of clamping openings for clamping the strip. The clamping component 11 is used to drive the strip to move along the length direction of the strip. The conveying mechanism 2 includes a lifting component 21 and a conveying component 22. The conveying component 22 is arranged between the two clamping components 11. The conveying component 22 moves along the first direction X. The lifting component 21 is connected to the conveying component 22. The lifting component 21 is used to drive the conveying component 22 to move along the second direction Y, so that both ends in the width direction of the strip respectively enter the clamping openings of the two clamping components 11. The first direction X and the second direction Y are intersectingly arranged.
[0039] Optionally, the two clamping components 11 can be arranged at intervals along the third direction Z. The width direction of the strip can be the same as the third direction Z. The first direction X can be a horizontal direction, or the first direction X can also be the length direction of the strip. The second direction Y can be a vertical direction. The third direction Z can be respectively intersectingly arranged with the first direction X and the second direction Y.
[0040] Optionally, the strip has a certain flexibility, and the strip can be a battery separator.
[0041] In the transmission device 100 provided by the present application, the clamping mechanism 1 includes two clamping components 11 arranged at intervals, and the conveying component 22 of the conveying mechanism 2 is located between the two clamping components 11. The starting end or the broken end of the strip can be placed on the conveying mechanism 2. The lifting component 21 can drive the conveying component 22 to move along the second direction Y to lift the strip. When the strip touches the clamping component 11, both ends in the width direction of the strip are respectively bent, so that the strip can avoid the clamping component 11. When the strip moves to the clamping opening of the clamping component 11, both ends in the width direction of the strip return to be flat, thereby realizing that the strip enters the clamping openings of the two clamping components 11.
[0042] The width of the strip should be slightly larger than the linear distance between the two clamping components 11, so that both ends of the strip in the width direction can enter the clamping openings of the clamping components 11 under the lifting action of the conveying component 22 along the second direction Y, and automatic film threading can be achieved. Therefore, the transmission device 100 provided in this application can automatically thread the strip, thereby reducing the cost of manual film threading. Moreover, by automatically threading the strip through the transmission device 100, the film surface quality and film threading efficiency of the strip can be improved.
[0043] The strip can also be transported to between the two clamping components 11 by other transfer devices. At this time, the strip itself will have a certain moving speed, and a relative displacement will be generated between the conveying mechanism 2 and the strip due to different moving speeds, and friction will be generated between the conveying mechanism 2 and the strip. In order to reduce the friction generated between the conveying mechanism 2 and the strip due to relative displacement, the conveying mechanism 2 can include a driving member to drive the conveying component 22 to move along the first direction X. It can be controlled that the moving directions and moving speeds of the conveying component 22 and the strip are the same, so that a relatively static state is formed between the conveying component 22 and the strip. In this way, when the conveying component 22 lifts the strip, it will have the same motion state as the strip, which can reduce the friction force generated between the conveying component 22 and the strip, and further reduce the influence of the conveying component 22 on the strip.
[0044] Optionally, the clamping component 11 can include a first clamping piece and a second clamping piece that are hinged to each other. A clamping opening is formed between the first clamping piece and the second clamping piece. The first clamping piece and the second clamping piece can approach or move away from each other to reduce or increase the opening angle of the clamping opening. The opening angle of the clamping opening can be reasonably set according to the thickness of the strip clamped by the clamping component 11. When the thickness of the strip is relatively thick, the opening angle between the first clamping piece and the second clamping piece can be appropriately increased. On the contrary, when the thickness of the strip is relatively thin, the opening angle between the first clamping piece and the second clamping piece can be appropriately reduced.
[0045] Optionally, the clamping component 11 can further include a sensor. The sensor can be arranged on the first clamping piece or the second clamping piece. The sensor can sense whether the strip enters the clamping opening. After the strip enters the clamping opening, the sensor can control the first clamping piece and the second clamping piece to approach each other to reduce the opening angle, so as to clamp the strip. After the strip threading is completed, the sensor can control the first clamping piece and the second clamping piece to move away from each other to increase the opening angle, so that the strip can be transferred to the stretching roller path for stretching.
[0046] Optionally, the lifting component 21 can be a screw jack. The screw jack is connected to the conveying component 22 and drives the conveying component 22 to move along the second direction Y.
[0047] It can be understood that in order for the clamping openings of the two spaced clamping assemblies 11 to respectively clamp both sides in the width direction of the strip, the width of the strip needs to be slightly greater than the straight-line distance between the two clamping assemblies 11. In this application, no specific regulations are made for the straight-line distance between the two spaced clamping assemblies 11, and the straight-line distance between the two clamping assemblies 11 can be appropriately adjusted according to the width of the strip clamped by the clamping assemblies 11.
[0048] It can be understood that after the strip is threaded through with the clamping assembly 11, the clamping assembly 11 can drive the strip to move to the strip stretching station. After the strip is threaded through, the conveying assembly 22 can also manually or automatically stop moving in the first direction X, and the lifting assembly 21 can continue to drive the conveying assembly 22 to move in the second direction Y away from the plane where the clamping opening is located, so as to reset the conveying assembly 22.
[0049] In some alternative embodiments, the clamping assembly 11 further includes a chain 111 and at least two sprockets 112. The chain 111 is sleeved on the sprockets 112 and is movably arranged around the sprockets 112. The clamping opening is connected to the side of the chain 111 away from the sprockets 112.
[0050] In these alternative embodiments, the clamping opening is connected to the side of the chain 111 away from the sprockets 112. The chain 111 is sleeved on the sprockets 112 and moves around the sprockets 112. The clamping opening will move with the movement of the chain 111, and the strip clamped on the clamping opening will also move with the clamping opening, so that the strip moves to the next processing station. The sprockets 112 can be two or more, and two or more sprockets 112 can improve the stability of the movement of the chain 111.
[0051] In some alternative embodiments, the conveying assembly 22 includes a conveyor belt 221 and at least two support rollers 222. The conveyor belt 221 is movably arranged around the support rollers 222.
[0052] In these alternative embodiments, the conveying assembly 22 further includes a driving member for driving the support rollers 222 to rotate, so as to drive the conveyor belt 221 to move around the support rollers 222. Optionally, the conveying assembly 22 further includes a housing 224 connected to both ends of the conveyor belt 221 in the width direction. The housing 224 can protect both ends of the conveyor belt 221 in the width direction. Optionally, the housing 224 can be made of a metal material after mirror polishing, such as stainless steel. The surface of the housing 224 after mirror polishing is smooth and burr-free, which can reduce the friction generated when the conveyor belt 221 contacts the strip, and thus can further reduce the influence of the conveying assembly 22 on the movement state of the strip.
[0053] In some alternative embodiments, the conveying assembly 22 further includes a plurality of suction holes 223 provided in the conveyor belt 221 and an air chamber communicating with the plurality of suction holes 223. The conveying mechanism 2 further includes an air duct 24 and a vacuum pump 25 that are connected in communication. The air duct 24 communicates with the air chamber, and the vacuum pump 25 is configured to drive external gas to enter the air chamber through the suction holes 223 so that the conveyor belt 221 adsorbs the strip material.
[0054] In these alternative embodiments, the conveying assembly 22 further includes a plurality of side walls 225. The plurality of side walls 225 enclose to form an air chamber between the conveyor belt 221 and the support roller 222. The air chamber communicates with the suction holes 223 and the air duct 24 respectively, and the air duct 24 communicates with the air chamber. Therefore, the vacuum pump 25 can sequentially absorb external gas through the air duct 24, the air chamber, and the suction holes 223, so as to generate an adsorption force in the suction holes 223 to adsorb the strip material.
[0055] Optionally, the suction holes 223 can be regularly arrayed on the conveyor belt 221, so that the adsorption force generated by the suction holes 223 on the conveyor belt 221 will be more balanced, and the strip material can fit more flatly on the conveyor belt 221. In this way, the film surface quality of the strip material can be improved. Optionally, the shape of the suction holes 223 can be circular, elliptical, polygonal or other shapes. The present application does not specifically limit this.
[0056] Preferably, the suction holes 223 are elliptical, and the ratio of the major axis to the minor axis of the elliptical suction holes 223 can be 3:2. In one embodiment, the major axis and the minor axis of the elliptical suction holes 223 can be 15 mm and 10 mm respectively. In this way, the adsorption force generated by the vacuum pump 25 through the suction holes 223 can be more uniform.
[0057] Optionally, the adsorption air pressure of the vacuum pump 25 can be from -70 mbar to -200 mbar.
[0058] In some alternative embodiments, the air duct 24 is a flexible air duct.
[0059] In these alternative embodiments, the flexible air duct 24 has good bending performance, is not easily broken, and is convenient for installation and disassembly. Optionally, the air duct 24 can be a polyurethane hose. The polyurethane hose has excellent properties such as anti-tensile and strong tension, and the thickness of the polyurethane hose is relatively thin and is easy to bend. Therefore, the air duct 24 made of polyurethane hose material can increase the service life of the air duct 24.
[0060] In some alternative embodiments, the conveying mechanism 2 further includes a measurement and control component 26. The measurement and control component 26 is electrically connected to the lifting component 21. The measurement and control component 26 is configured to control the lifting component 21 to move along the second direction Y and measure the distance that the conveying component 22 moves along the second direction Y.
[0061] In these alternative embodiments, the measurement and control component 26 is electrically connected to the lifting component 21. The measurement and control component 26 can control the lifting component 21 to move along the second direction Y. The lifting component 21 drives the conveying component 22 to move along the second direction Y and can sense whether the heights of the conveying component 22 and the clamping component 11 are flush. When the heights of the conveying component 22 and the clamping component 11 are not flush, the measurement and control component 26 can control the lifting component 21 to drive the conveying component 22 to move along the second direction Y so that the heights of the conveying component 22 and the clamping component 11 are flush.
[0062] Optionally, the measurement and control component 26 can include a grating scale, and the lifting component 21 can include a driving motor. The grating scale can measure the distance that the conveying component 22 moves along the second direction Y, and the driving motor can control the lifting component 21 to move along the second direction Y. The detection accuracy of the grating scale is relatively high and the response speed is fast. The measurement and control component 26 can obtain the distance that the conveying component 22 moves along the second direction Y in a timely and rapid manner.
[0063] Optionally, the grating scale can be driven by a DC (direct current) power supply, and the working voltage of the grating scale can be selected as DC5 - 24V.
[0064] In some alternative embodiments, the conveying mechanism 2 further includes a roller assembly 23. The roller assembly 23 and the conveying component 22 are arranged between the two clamping components 11 along the third direction Z. The third direction Z, the first direction X, and the second direction Y intersect pairwise.
[0065] In these alternative embodiments, since the width of the commonly used conveyor belt 221 is generally about 0.5 m at present, when the width of the strip is relatively wide, for example, the strip width is 3 m - 4 m, it is difficult for the 0.5 m conveyor belt 221 to lift the strip smoothly. In the case where the width difference between the conveyor belt 221 and the strip is large, and in order to reduce the cost of the transmission device 100 and improve the multi-scenario usage performance of the transmission device 100, the conveying mechanism 2 may further include a roller assembly 23. The roller assembly 23 and the conveying assembly 22 are arranged along the third direction Z between the two clamping assemblies 11, and the height of the roller assembly 23 may be flush with the height of the clamping assemblies 11. In this way, the roller assembly 23 and the conveying assembly 22 can jointly lift the strip so that the strip enters the clamping opening and the strip is membrane-passed. The process of jointly membrane-passing the two sides of the strip width by the roller assembly 23 and the conveying assembly 22 may include: the conveying assembly 22 is lifted by the lifting assembly 21 along the second direction Y, the vacuum pump 25 is turned on to generate an adsorption force in the adsorption holes 223, and the conveyor belt 221 adsorbs the strip. At this time, one side of the strip width direction close to the conveying assembly 22 will bend so that the strip can avoid the clamping assembly 11. When the strip moves to the clamping opening of the clamping assembly 11, the bent side of the strip along the width direction will return to flat, so that one side of the strip enters the clamping opening of one clamping assembly 11. After one side of the strip is membrane-passed, it will move with the clamping assembly 11. Under the combined action of the inertia of the membrane-passed side of the strip and the roller assembly 23, the other side of the strip width direction will also enter the clamping opening of the clamping assembly 11, and automatic membrane-passing is achieved. After the membrane-passing is completed, the vacuum pump 25 can be turned off, and the lifting assembly 21 can continue to drive the conveying assembly 22 to move along the second direction Y to reset the conveying assembly 22.
[0066] Optionally, the third direction Z may be the direction between the two clamping assemblies 11, the first direction X may be the length direction of the conveyor belt 221, the second direction Y may be the vertical direction, and the first direction X, the second direction Y, and the third direction Z may be perpendicular to each other pairwise.
[0067] In some alternative embodiments, the roller assembly 23 includes a plurality of rollers 231, and the plurality of rollers 231 are arranged at intervals along the first direction X.
[0068] In these alternative embodiments, the plurality of rollers 231 may be arranged at equal intervals along the first direction X, and the distance between two adjacent rollers 231 may be 300 mm.
[0069] Optionally, the roller assembly 23 may further include brackets extending along the first direction X. There may be two brackets, which are spaced apart along the third direction Z. The two brackets connect the two ends of a plurality of rollers 231 and connect and support the plurality of rollers 231. The roller 231 may be made of hollow aluminum material, so that the weight of the roller 231 can be reduced. Optionally, the diameter of the roller 231 may be φ80.
[0070] Please refer to Figure 3 , Figure 3 which is a schematic diagram of a strip processing device provided in the second aspect embodiment of the present application. The second aspect embodiment of the present application provides a strip processing device 200, including: a stretcher 201 and the transmission device 100 provided in any embodiment of the first aspect of the present application. The stretcher 201 includes a strip inlet, and the transmission device 100 is used to transmit the strip to the strip inlet.
[0071] In these alternative embodiments, after the strip passes through the transmission device 100 for film threading, it continues to move with the transmission device 100. The transmission device 100 moves the strip to the strip inlet, and the strip can be threaded and stretched inside the stretcher 201.
[0072] In some alternative embodiments, the strip processing device 200 further includes a film break detection member 202. The film break detection member 202 is connected to the stretcher 201. The film break detection member 202 is used to send a detection signal to the strip and receive the reflected signal reflected by the strip.
[0073] In these alternative embodiments, the film break detection member 202 may be disposed at the strip inlet. The film break detection member 202 is used to send a detection signal to the strip. The strip reflects the detection signal to form a reflected signal. The film break detection member 202 is further used to receive the reflected signal reflected by the strip, so that it can detect whether the strip has an abnormality such as film breakage inside the stretcher 201 according to the reflected signal. When a film break abnormality occurs in the stretcher oven 201, the two film break detection members 202 act simultaneously, and the strip processing device 200 can automatically detect it. The strip processing device 200 can control the conveyor belt 221 and the vacuum pump 25 system to start through a logical AND signal. The strip enters the stretcher oven 201 again by relying on the adsorption holes 223, the conveyor belt 221 and the guide roller 231, thereby improving the stable operation efficiency of the equipment and achieving the purpose of automatic film threading of the stretcher system.
[0074] Optionally, the film break detection member 202 may be connected to the function key module of the stretcher 201, so that an operator can operate the function key module to control the working state of the film break detection member 202.
[0075] Optionally, in order to reduce the cost of the strip processing device 200, there may be two film breaking detection members 202. Alternatively, the number of the film breaking detection members 202 may be multiple, and the multiple film breaking detection members 202 may be arranged at intervals along the strip inlet to improve the detection accuracy.
[0076] Optionally, the film breaking detection member 202 may be a fiber optic sensor. The bending radius of the fiber optic sensor may be 70 mm, and a bending radius of 70 mm can reduce the detection error of the fiber optic sensor.
[0077] Optionally, the stretcher 201 may further include an oven, and the strip may be stretched and baked in the oven. Since the film breaking detection member 202 is connected to the stretcher 201, in order to improve the service life of the film breaking detection member 202, a film breaking detection member 202 that can withstand at least a temperature of 200 °C should be selected.
[0078] The embodiments of the second aspect of the present application have the beneficial effects of the embodiments of the first aspect of the present application, which will not be elaborated herein.
