Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, specifically to an automatic conveyor belt correction device and a stacking system. Background Technology

[0002] Conveyor belt systems are widely used for material transport. They mainly consist of a drive roller, a driven roller, and a conveyor belt. Driven by the drive roller, the conveyor belt circulates around both the drive and driven rollers. During actual operation, uneven material distribution on the conveyor belt and the influence of belt tension often cause the driven roller to tilt, resulting in belt skew. However, in existing conveyor belt systems, belt skew requires manual detection, and once skew occurs, the machine typically needs to be stopped for manual correction. Automatic correction is not possible, leading to low efficiency.

[0003] In the electrode conveying process, a conveyor belt is arranged around the outside of a vacuum chamber. The vacuum chamber has through holes for negative pressure airflow, and the conveyor belt has vacuum adsorption holes. The negative pressure airflow passes through the through holes and forms a negative pressure at the vacuum adsorption holes on the conveyor belt, adsorbing the electrodes. If the conveyor belt shifts, the vacuum adsorption holes on the conveyor belt will deviate from the through holes on the vacuum chamber, reducing the adsorption effect on the electrodes. Furthermore, if the conveyor belt shifts, the electrodes on the conveyor belt will also shift, meaning the electrodes will be in a shifted state when entering the next process. If this shift is not corrected, it will affect the normal stacking of subsequent electrodes. Utility Model Content

[0004] In view of this, the present invention provides an automatic belt correction device and a stacking system to solve the problem that the conveyor belt device cannot automatically correct its deviation.

[0005] In a first aspect, this utility model provides an automatic conveyor belt correction device, comprising: a conveying unit, including a frame, a drive roller, a driven roller, and a conveyor belt, wherein the drive roller is fixedly connected to one end of the frame, the driven roller is disposed on the frame at an end away from the drive roller, a first end of the driven roller is rotatably connected to the frame and a second end is movably connected to the frame, and the conveyor belt is wound between the drive roller and the driven roller; a driving unit connected to the second end of the driven roller, the driving unit being adapted to drive the second end of the driven roller to deflect relative to the first end of the driven roller; a detection unit disposed along the width direction of the conveyor belt on at least one side of the conveyor belt to detect the offset of the conveyor belt; and a control module electrically connected to both the driving unit and the detection unit, the control module being adapted to control the operation of the driving unit according to the detection signal of the detection unit.

[0006] Beneficial effects: By setting the first end of the driven roller to be rotatably connected to the frame and the second end to be movablely connected to the frame, and connecting the second end of the driven roller to a drive unit, the drive unit can drive the second end of the driven roller to rotate around the connection point between the first end of the driven roller and the frame. By setting a detection unit on at least one side of the conveyor belt along the width direction, the detection of whether the conveyor belt is off-track and the direction of deviation can be realized. At the same time, by setting a control module, and both the detection unit and the drive unit are electrically connected to the control module, the control module can control the action of the drive unit according to the conveyor belt deviation information fed back by the detection unit. Thus, the drive unit drives the second end of the driven roller to deflect relative to its first end, thereby controlling the deflection angle of the driven roller and controlling the amount of conveyor belt deviation. This achieves automatic correction of the conveyor belt, prevents skewing during material transportation, improves the stability of material transmission, ensures the assembly accuracy of materials in subsequent assembly processes, improves the product qualification rate, and saves costs.

[0007] Secondly, this utility model also provides a lamination system, including the aforementioned automatic conveyor belt correction device. Since the lamination system includes the automatic conveyor belt correction device and has the same effect as the automatic conveyor belt correction device, it will not be described in detail here.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0021] According to an embodiment of the present invention, an automatic belt correction device is provided, comprising: a conveying unit 1, a driving unit 2, a detection unit 3, and a control module. The conveying unit 1 includes a frame 101, a drive roller 102, a driven roller 103, and a conveyor belt 104. The drive roller 102 is fixedly connected to one end of the frame 101, and the driven roller 103 is disposed on the frame 101 at the end away from the drive roller 102. The first end of the driven roller 103 is rotatably connected to the frame 101, and the second end is movably connected to the frame 101. The conveyor belt 104 is wound between the drive roller 102 and the driven roller 103. The drive unit 2 is connected to the second end of the driven roller 103 and is adapted to drive the second end of the driven roller 103 to deflect relative to the first end of the driven roller 103. The detection unit 3 is disposed along the width direction of the conveyor belt 104 on at least one side of the conveyor belt 104 to detect the offset of the conveyor belt 104. The control module is electrically connected to both the drive unit 2 and the detection unit 3 and is adapted to control the operation of the drive unit 2 according to the detection signal of the detection unit 3. The first end and the second end of the driven roller 103 are two mutually distant ends on the driven roller 103 located along the extension direction of its axis. Specifically, the first end of the driven roller 103 refers to the end along the axis of its axis. Figure 1 The end indicated by the middle arrow in the "width direction" refers to the second end of the driven roller 103, which is along the width direction. Figure 1 The other end indicated by the middle arrow in the "width direction"; the width direction of conveyor belt 104 refers to... Figure 1 The middle arrow points to the "width direction".

[0022] The automatic conveyor belt correction device of this embodiment is configured such that the first end of the driven roller 103 is rotatably connected to the frame 101 and the second end is movably connected to the frame 101, and a drive unit 2 is connected to the second end of the driven roller 103. The drive unit 2 can drive the second end of the driven roller 103 to rotate around the connection point between the first end of the driven roller 103 and the frame 101. By setting a detection unit 3 along the width direction on at least one side of the conveyor belt 104, the device can detect whether the conveyor belt 104 is misaligned and the direction of deviation. Simultaneously, by setting a control module and the detection unit 3... All drive units 2 are electrically connected to the control module. The control module can control the action of drive units 2 based on the offset information of conveyor belt 104 fed back by detection unit 3. Thus, drive units 2 drive the second end of driven roller 103 to deflect relative to its first end, thereby controlling the deflection angle of driven roller 103 and controlling the offset of conveyor belt 104. This enables automatic correction of conveyor belt 104, prevents skewing during material conveying, improves material transmission stability, ensures assembly accuracy in subsequent assembly processes, increases product qualification rate, and saves costs.

[0023] It should be noted that further integration Figure 1 and Figure 6As shown, frame 101 along Figure 1 and Figure 6 Extending in the "first direction" indicated by the middle arrow, the driving roller 102 and the driven roller 103 are located at both ends of the first direction. The conveyor belt 104 is wound between the driving roller 102 and the driven roller 103. The driving roller 102 is connected to a drive structure such as a motor. The drive structure drives the driving roller 102 to rotate. The driving roller 102 drives the conveyor belt 104 to move cyclically along the first direction. The first direction is the conveying direction of the conveyor belt 104. The driven roller 103 plays a supporting and guiding role.

[0024] In one embodiment, the detection unit 3 is a position detection sensor, which has a simple structure and low cost. Preferably, the detection unit 3 is a photoelectric sensor, which has advantages such as high sensitivity, high accuracy, fast response speed, and ease of use.

[0025] In one embodiment, further combination Figures 3 to 4 and Figures 7 to 8 As shown, the photoelectric sensor is fixedly connected to the frame 101. The photoelectric sensor is used to detect the offset information of the conveyor belt 104 located on the lower side. The photoelectric sensor corresponds precisely to the side of the conveyor belt 104. Therefore, based on the presence or absence of the conveyor belt 104 detected by the photoelectric sensor, the direction of deviation of the conveyor belt 104 can be determined. Here, "lower side" refers to... Figure 3 and Figure 7 The side indicated by the middle arrow pointing "down". It can be understood that, as an alternative implementation, the photoelectric sensor can also be fixed to the support body (not shown in the figure) used to fix the frame 101, which can also realize the detection of the position information of the lower conveyor belt 104.

[0026] In one embodiment, there are two detection units 3, one on each side of the conveyor belt 104 along its width direction. By setting two detection units 3 and one on each side of the conveyor belt 104, the conveyor belt 104 can be detected simultaneously on both sides along its width direction. By combining the detection results of the two detection units 3, the direction of deviation of the conveyor belt 104 can be accurately determined, thereby further improving the accuracy of the detection results and the reliability of the correction results.

[0027] In one embodiment, further combination Figure 3As shown, the frame 101 includes a vacuum chamber 1011. An adsorption area is constructed on the upper side of the vacuum chamber 1011, and a through hole communicating with the inside and outside of the vacuum chamber 1011 is formed in the adsorption area. An adsorption hole is formed on the conveyor belt 104. The material conveyed on the conveyor belt 104 is an electrode sheet. By automatically correcting the conveyor belt 104, it is ensured that the conveyor belt 104 is in close contact with the adsorption area of ​​the vacuum chamber 1011, and the adsorption hole on the conveyor belt 104 coincides with the through hole in the adsorption area. This ensures that vacuum adsorption is maintained during the electrode sheet transmission process, preventing electrode sheet skewing during transmission and thus improving the stability of electrode sheet transmission. The automatic conveyor belt correction device of this embodiment can be used in belt vacuum adsorption electrode sheet transmission mechanisms such as slicing machines and slicing-stacking integrated machines.

[0028] In one embodiment, the conveyor belt 104 is a belt, which has advantages such as flexible layout, long service life, smooth conveying, and low cost.

[0029] In one embodiment, further combination Figures 7 to 8 As shown, a fixed shaft 4 is provided on the first side of the frame 101 along its width direction. The axis of the fixed shaft 4 extends vertically and is perpendicular to the axis of the driven roller 103. The fixed shaft 4 is fixed relative to the frame 101 and passes through the driven roller 103. The first end of the driven roller 103 is rotatably sleeved on the fixed shaft 4. The width direction of the frame 101 is the same as the width direction of the conveyor belt 104, i.e. Figures 7 to 8 The middle arrow points to the "width direction"; the vertical direction refers to... Figures 7 to 8 The direction indicated by the middle arrow is "up and down". By setting a fixed shaft 4 along the width direction of the frame 101 on the first side of the frame 101 and passing through the driven roller 103, the driven roller 103 is connected to the frame 101 through the fixed shaft 4. By setting the driven roller 103 to be rotatably sleeved on the fixed shaft 4 and the axis of the fixed shaft 4 being perpendicular to the axis of the driven roller 103, the driven roller 103 can be deflected by rotating around the axis of the fixed shaft 4. Since the fixed shaft 4 is relatively fixed to the frame 101, the first end of the driven roller 103 is rotatably connected to the frame 101, so that when the conveyor belt 104 deviates, the second end of the driven roller 103 is driven by the drive unit 2 to deflect around the first end to correct the deviation of the conveyor belt 104.

[0030] It should be noted that during the deflection of the driven roller 103, the plane swept by the axis of the driven roller 103 is perpendicular to the axis of the fixed shaft 4.

[0031] In one embodiment, further combination Figure 7As shown, the automatic belt correction device further includes: a first fixed block 5, which is disposed on the first side of the frame 101 and fixedly connected to the frame 101. A first clearance groove 501 is provided on the first fixed block 5. A fixed shaft 4 is connected to the first fixed block 5 and passes through the first clearance groove 501 in the vertical direction. The first end of the driven roller 103 is located in the first clearance groove 501. In the conveying direction along the conveyor belt 104, the size of the first clearance groove 501 is larger than the range of motion of the first end of the driven roller 103. By fixing a first fixing block 5 to the first side of the frame 101 along its width direction and connecting a fixing shaft 4 to the first fixing block 5, the fixing shaft 4 is connected to the frame 101 through the first fixing block 5, thereby achieving relative fixation of the position of the fixing shaft 4 and the frame 101. At the same time, by opening a first clearance groove 501 on the first fixing block 5 and passing the fixing shaft 4 through the first clearance groove 501 in the vertical direction, the first end of the driven roller 103 sleeved on the fixing shaft 4 is located in the first clearance groove 501. Furthermore, by setting the dimension of the first clearance groove 501 along the conveying direction to be larger than the range of motion of the first end of the driven roller 103 along the conveying direction, the first end of the driven roller 103 is movably located in the first clearance groove 501 along the conveying direction. On the one hand, the first clearance groove 501 provides rotation space for the rotation of the driven roller 103, facilitating the rotation of the driven roller 103 relative to the frame 101. On the other hand, the first fixing block 5 has a structural strengthening function, which can strengthen the support of the driven roller 103 and improve the structural stability and reliability.

[0032] The opening of the first clearance groove 501 has an elongated oval shape and extends along the conveying direction of the conveyor belt 104. The dimension of the first clearance groove 501 along its extension direction is larger than the radial dimension of the driven roller 103, so that the first clearance groove 501 can provide rotation space for the first end of the driven roller 103 during the movement of the second end of the driven roller 103 along the conveying direction of the conveyor belt 104. The dimension of the first clearance groove 501 in the vertical direction is slightly larger than the radial dimension of the driven roller 103. On the one hand, this ensures that the driven roller 103 can be movably located in the first clearance groove 501 to facilitate the rotation of the driven roller 103. On the other hand, it limits the driven roller 103 in the vertical direction and improves the stability of the driven roller 103 during the deflection process.

[0033] Preferably, the fixed shaft 4 is fixedly connected to the first fixed block 5, which can further ensure the stability of the overall structure.

[0034] In one embodiment, the frame 101 includes a vacuum chamber 1011 and side plates 1012 fixedly connected to the vacuum chamber 1011. There are four side plates 1012. Two side plates 1012 are provided at each end of the vacuum chamber 1011 along the conveying direction of the conveyor belt 104, and one side plate 1012 is provided on each side of the width direction at each end of the vacuum chamber 1011. The first fixing block 5 is fixedly connected to one side plate 1012, thereby realizing the fixed connection between the first fixing block 5 and the frame 101, and the structure has good stability.

[0035] It should be noted that the vacuum chamber 1011 extends along the conveying direction of the conveyor belt 104. At each end of the vacuum chamber 1011 in its extending direction, there is a roller 105. The axis of the roller 105 is parallel to the axis of the drive roller 102. The drive roller 102 and the driven roller 103 are both located below the vacuum chamber 1011. The conveyor belt 104 passes around the drive roller 102, the two rollers 105 at both ends of the vacuum chamber 1011, and the driven roller 103 in sequence before reaching the drive roller 102, thereby realizing the cyclic movement of the conveyor belt 104 around the rollers. Preferably, the conveying unit 1 further includes a tensioning roller 106 and a support roller 107 disposed below the vacuum chamber 1011 and between the driving roller 102 and the driven roller 103. There is one tensioning roller 106 and two support rollers 107. The tensioning roller 106 is used to tension the conveyor belt 104 to improve the stability of the conveying process. A support roller 107 is disposed on each side of the tensioning roller 106 and is located between the tensioning roller 106 and the vacuum chamber 1011. The support rollers 107 are used to redirect and support the conveyor belt 104.

[0036] In other embodiments, the first fixing block 5 may not be provided. Instead, a first clearance groove may be opened directly on a side plate 1012 located on the first side of the frame 101. This can also achieve the supporting function of the frame 101 on the first end of the driven roller 103 and the clearance function of providing rotation space for the driven roller 103. The structure is also simple.

[0037] In one embodiment, further combination Figures 3 to 4As shown, the frame 101 has side plates 1012 on both sides along its width direction. A first through groove 1014 is provided on one of the side plates 1012 on the second side of the frame 101 in the width direction. The first through groove 1014 passes through the side plate 1012 along the width direction of the frame 101 and extends along the conveying direction of the conveyor belt 104. The second end of the driven roller 103 passes through the first through groove 1014. It should be noted that the driven roller 103 is connected to two side plates 1012 located on both sides of the frame 101 in the width direction. By opening a first through groove 1014 through the side plate 1012 located on the second side of the frame 101, the second end of the driven roller 103 can be assembled with the frame 101 through the first through groove 1014. At the same time, by setting the first through groove 1014 to extend along the conveying direction of the conveyor belt 104, the driven roller 103 can move relative to the frame 101 along the conveying direction of the conveyor belt 104, thereby ensuring that the second end of the driven roller 103 can be deflected relative to its first end, and thus the conveyor belt 104 can be corrected, ensuring the smooth progress of the automatic correction process.

[0038] Specifically, the first through groove 1014 is an elongated strip extending along the conveying direction of the conveyor belt 104. On the one hand, it provides movement space for the second end of the driven roller 103 to move relative to the frame 101 along the conveying direction, and at the same time limits the maximum displacement of the driven roller 103 along the conveying direction. On the other hand, the first through groove 1014 limits the driven roller 103 in the up and down direction, thereby ensuring that the driven roller 103 can only move relative to the frame 101 along the conveying direction of the conveyor belt 104, and improving the smoothness of the deflection process of the driven roller 103.

[0039] In one embodiment, further combination Figures 3 to 4 As shown, a first through hole 1013 is provided on the side plate 1012 on the first side of the frame 101 in the width direction. A first fixing block 5 is fixedly connected to the first side of the side plate 1012. A relief groove 501 on the first fixing block 5 corresponds to the first through hole 1013. The diameter of the first through hole 1013 is larger than the radial dimension of the driven roller 103, so as to ensure that the first through hole 1013 can also provide space to avoid the deflection of the driven roller 103. The first relief groove 501 is a through groove that passes through the first fixing block 5 in the width direction of the frame 101. The first end of the driven roller 103 passes through the first through hole 1013 and then through the first relief groove 501.

[0040] In one embodiment, further combination Figure 3As shown, the automatic belt correction device further includes a second fixing block 6, which is disposed on the second side of the frame 101 along its width direction and is fixedly connected to the frame 101. The second fixing block 6 has a second clearance groove 601 corresponding to the first through groove 1014. The second end of the driven roller 103 passes through the first through groove 1014 and the second clearance groove 601 and is connected to the drive unit 2. In the conveying direction along the conveyor belt 104, the dimensions of the first through groove 1014 and the second clearance groove 601 are both larger than the range of motion of the second end of the driven roller 103. By fixing a second fixing block 6 to the second side of the frame 101 along its width direction, and opening a second clearance groove 601 on the second fixing block 6 corresponding to the first through groove 1014, the driven roller 103 can pass through the first through groove 1014 and the second clearance groove 601. Furthermore, by setting the dimensions of the first through groove 1014 and the second clearance groove 601 along the conveying direction to be larger than the range of motion of the second end of the driven roller 103 along the conveying direction, the second end of the driven roller 103 can be movably located in the first through groove 1014 and the second clearance groove 601 along the conveying direction. The first through groove 1014 and the second clearance groove 601 provide clearance space for the movement of the second end of the driven roller 103, facilitating the movement of the second end of the driven roller 103 relative to the frame 101. At the same time, the second fixing block 6 has a structural strengthening function, which can strengthen the support of the driven roller 103 and improve the structural stability and reliability.

[0041] It should be noted that the second clearance groove 601 is a through groove. The second clearance groove 601 passes through the second fixed block 6 along the width direction of the frame 101. The second clearance groove 601 is a long strip extending along the conveying direction of the conveyor belt 104, allowing the driven roller 103 to move along the conveying direction of the conveyor belt 104.

[0042] In one embodiment, the drive unit 2 includes a connecting portion 201 and a telescopic portion 202. The connecting portion 201 is hinged to the frame 101, and the telescopic portion 202 is telescopic relative to the connecting portion 201. One end of the telescopic portion 202 away from the connecting portion 201 is rotatably connected to the second end of the driven roller 103. By providing the drive unit 2 with the connecting portion 201 and the telescopic portion 202 that is telescopic relative to the connecting portion 201, and by providing the connecting portion 201 to the frame 101, the angle between the axis of the driven roller 103 and the axis of the telescopic portion 202 remains unchanged during the telescopic portion 202's extension and retraction. The telescopic portion 202 then drives the driven roller 103 to move and drives the connecting portion 201 to rotate relative to the frame 101. This allows the angle between the axis of the telescopic portion 202 and the conveying direction to be adaptively adjusted as the telescopic portion 202 extends and retracts, thereby enabling the telescopic portion 202 to drive the second end of the driven roller 103 to move relative to the frame 101 during the extension and retraction process.

[0043] Specifically, further integration Figure 4As shown, a bushing 203 is provided at one end of the connecting rod away from the telescopic part 202. A ball 1031 that wraps around the roller shaft is fixedly connected to the roller shaft of the driven roller 103. The bushing 203 is rotatably sleeved on the outside of the ball 1031. The driven roller 103 is rotatably sleeved inside the bushing 203, realizing the rotational connection between the driven roller 103 and the telescopic part 202.

[0044] In addition, in other embodiments, further combined Figures 3 to 4 As shown, the drive unit 2 includes a connecting part 201, a telescopic part 202 and a connecting rod. The connecting part 201 is fixed relative to the frame 101. The telescopic part 202 can extend and retract relative to the connecting part 201. The first end of the connecting rod is hinged to the end of the telescopic part 202 away from the connecting part 201, and the second end of the connecting rod is hinged to the second end of the driven roller 103. By setting the drive unit 2 to include a connecting part 201 fixed relative to the frame 101 and a telescopic part 202 that can extend and retract relative to the connecting part 201, the telescopic part 202 can extend and retract relative to the frame 101. At the same time, by hinged a connecting rod to the telescopic part 202, with one end of the connecting rod away from the telescopic part 202 hinged to the second end of the driven roller 103, the angle between the axis of the driven roller 103 and the extension and retraction direction of the telescopic part 202 can be adaptively adjusted as the telescopic part 202 extends and retracts. Thus, the telescopic part 202 drives the second end of the driven roller 103 to move relative to the frame 101 during the extension and retraction process, and the deflection of the driven roller 103 is achieved while the extension and retraction direction of the telescopic part 202 remains unchanged. The structure is simple and has high stability.

[0045] The telescopic part 202 extends and retracts relative to the connecting part 201 along the conveying direction of the conveyor belt 104, thereby driving the second end of the driven roller 103 to move relative to the frame 101 along the conveying direction of the conveyor belt 104. Optionally, the connecting part 201 is directly fixedly connected to the frame 101, or the connecting part 201 is fixedly connected to the support body used to fix the frame 101, both of which can achieve relative fixation between the connecting part 201 and the frame 101.

[0046] In one embodiment, the drive unit 2 is a telescopic cylinder. Telescopic cylinders have high strength, good stability, mature technology, wide application, and high reliability.

[0047] Optionally, the telescopic cylinder is a pneumatic cylinder. The cylinder pressure is adjusted via a pressure regulating valve or an electro-proportional valve, thereby regulating the extension and retraction of the telescopic part 202 relative to the connecting part 201. This drives the movement of the second end of the driven roller 103, thus controlling the deflection angle of the driven roller 103. It should be noted that, ideally, the axis of the driven roller 103 is parallel to the axis of the driving roller 102.
