Description

Transport devices and stacking equipment

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on July 21, 2023, with application number 202321949982.X and application name “Transportation Device and Lamination Equipment,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the technical field of battery production equipment, and in particular to a transportation device and a stacking device. Background Art

[0003] In related technologies, the lamination process involves cutting electrode strips into sheet-like electrodes, which are then laminated with a separator to form a battery cell. This process results in a battery cell with low internal resistance, improved charge and discharge power, high lamination utilization, a larger electrode area, and a higher energy density.

[0004] In existing technology, stacking equipment uses an inverted belt to remove defective or non-compliant electrode sheets during transport, achieving waste removal. However, this method of waste removal using an inverted belt is unstable and prone to blockage, which in turn affects the stacking efficiency of the stacking equipment.

[0036] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] The technical solution of the present disclosure will be further described below with reference to specific embodiments and drawings.

[0038] Referring to FIG1 , the embodiment of the present disclosure discloses a transport device 1, comprising a first conveying mechanism 11 and a second conveying mechanism 12. The first conveying mechanism 11 has a first conveying surface 111, a first end 112, and a second end 113. The first conveying surface 111 is used to convey the electrode from the first end 112 toward the second end 113. Referring to FIG2 to FIG5 , the second conveying mechanism 12 is disposed on a side of the second end 113 away from the first end 112 and can reciprocate between a first position 121 and a second position 122. The second conveying mechanism 12 has a second conveying surface 123, a receiving end 124, and a conveying end 125. The second conveying surface 123 is used to convey the electrode from the receiving end 124 toward the conveying end 125. When the second conveying mechanism 12 is located in the first position 121, the plane where the second conveying surface 123 is located is coplanar with the plane where the first conveying surface 111 is located, and the pole piece is conveyed from the second end 113 to the conveying end 125 via the receiving end 124 and output from the conveying end 125; when the second conveying mechanism 12 is located in the second position 122, the plane where the second conveying surface 123 is located is parallel to or intersects with the plane where the first conveying surface 111 is located, and the pole piece is output from the second end 113 or the second conveying mechanism 12.

[0039] The transport device 1 has two modes: conveying and waste discharge. When the electrode being transported by the transport device 1 is qualified, the transport device 1 is in the conveying mode, i.e., the transport device 1 plays a conveying role and transports the qualified electrode to the subsequent process for subsequent processing; when the electrode being transported by the transport device 1 is waste electrode, the transport device 1 is in the waste discharge mode, i.e., the transport device 1 plays a waste discharge role and outputs the waste electrode for recycling.

[0040] Exemplarily, when the electrode located at the first conveying mechanism 11 is detected as a qualified electrode, the second conveying mechanism 12 moves to the first position 121. At this time, the first conveying mechanism 11 and the second conveying mechanism 12 are in conveying mode, that is, the first conveying mechanism 11 and the second conveying mechanism 12 convey the qualified electrode to the subsequent process for subsequent process processing; when the electrode located at the first conveying mechanism 11 is detected as a waste electrode, the second conveying mechanism 12 moves to the second position 122, and the first conveying mechanism 11 and the second conveying mechanism 12 switch to the waste discharge mode, that is, the first conveying mechanism 11 conveys the waste electrode for recycling, or the first conveying mechanism 11 and the second conveying mechanism 12 convey the waste electrode for recycling.

[0041] It should be noted that when the second conveying mechanism 12 is in the first position 121, the first conveying surface 111 of the first conveying mechanism 11 and the second conveying surface 123 of the second conveying mechanism 12 are oriented in the same direction and are coplanar with each other. In other words, the second conveying mechanism 12 is not in an upside-down manner, but is arranged in the same manner as the first conveying mechanism 11. When the first conveying surface 111 and the second conveying surface 123 are oriented in the same direction and are coplanar with each other, when the electrode is conveyed from the second end 113 of the first conveying mechanism 11 to the receiving end 124 of the second conveying mechanism 12, that is, when it is conveyed from the first conveying surface 111 to the second conveying surface 123, since the contact surface between the electrode and the first conveying mechanism 11 and the second conveying mechanism 12 is the same, the electrode will not be blocked between the first conveying mechanism 11 and the second conveying mechanism 12 due to factors such as uneven force on both sides, that is, no material blockage will occur, thereby improving the conveying efficiency of the transport device 1 and the stacking efficiency of the stacking equipment. It should be supplemented that, when the second conveying mechanism 12 moves to the second position 122 , the second conveying mechanism 12 is not in an upside-down manner.

[0042] Furthermore, when the second conveying mechanism 12 moves to the second position 122, the plane on which the second conveying surface 123 lies may be parallel to the plane on which the first conveying surface 111 lies, i.e., a gap is formed between the plane on which the second conveying surface 123 lies and the plane on which the first conveying surface 111 lies. The plane on which the second conveying surface 123 lies and the plane on which the first conveying surface 111 lies may also intersect, i.e., an angle is formed between the plane on which the second conveying surface 123 lies and the plane on which the first conveying surface 111 lies, i.e., the plane on which the second conveying surface 123 lies is inclined relative to the plane on which the first conveying surface 111 lies.

[0043] It is understandable that the qualified electrodes or waste electrodes mentioned above can be automatically detected by intelligent devices or manually detected, which is not limited here.

[0044] Referring again to Figure 1 , in the disclosed embodiment, both the first conveying mechanism 11 and the second conveying mechanism 12 include a vacuum belt 114 for sucking and conveying the electrode sheets. The first conveying surface 111 is located on the vacuum belt 114 of the first conveying mechanism 11, and the second conveying surface 123 is located on the vacuum belt 114 of the second conveying mechanism 12. Referring also to Figures 2-5 , the transport device 1 also includes a waste bin 13. When the second conveying mechanism 12 is in the second position 122, the electrode sheets are delivered to the waste bin 13 from the second end 113 or the second conveying mechanism 12.

[0045] Both the first conveying mechanism 11 and the second conveying mechanism 12 use a vacuum belt 114 to transport the electrode. Specifically, in addition to the vacuum belt 114, the first conveying mechanism 11 and the second conveying mechanism 12 also include a vacuum cavity, and the vacuum belt 114 is wrapped around the vacuum cavity. The vacuum belt 114 is provided with a through hole, which is connected to the vacuum cavity. The vacuum cavity forms a negative pressure. When the electrode is located on the vacuum belt 114, when the surface of the electrode that contacts the vacuum belt 114 fits the through hole, the electrode is adsorbed to the vacuum belt 114 by the negative pressure, so that the electrode is adsorbed to the vacuum belt 114 and transported by the vacuum belt 114. The use of the vacuum belt 114 for transportation makes the electrode transportation relatively stable through adsorption, thereby increasing the transportation rate and improving the transportation efficiency.

[0046] When the transport device 1 transports the scrap electrode pieces for recycling, the scrap electrode pieces can be collected in the waste bin 13 for centralized processing. For example, when the electrode piece located at the first conveying mechanism 11 is detected as a scrap electrode piece, the second conveying mechanism 12 moves to the second position 122. At this time, the first conveying mechanism 11 and the second conveying mechanism 12 switch to the waste discharge mode, that is, the first conveying mechanism 11 transports the scrap electrode piece to the waste bin 13, or the first conveying mechanism 11 and the second conveying mechanism 12 transport the scrap electrode piece to the waste bin 13 for recycling.

[0047] It is understandable that in the previous process of manufacturing the electrode, the electrode may not meet the specifications or performance standards due to various reasons, thereby turning the electrode into a scrap electrode and requiring recycling. And the scrap electrode can be divided into at least two categories. The first category of scrap electrode may be a defect on the electrode surface, and the second category of scrap electrode may be a defect in the electrode size. Of course, scrap electrode may also be divided into other categories, which are not limited here. In order to improve the efficiency of the corresponding treatment of the scrap electrode after recycling, the waste box 13 can also be distinguished according to the different classifications of the scrap electrode. For example, the waste box 13 can include a first waste box 131 and a second waste box 132. The first waste box 131 is used to recycle scrap electrode with defects on the electrode surface, and the second waste box 132 is used to recycle scrap electrode with defects in the electrode size. The above-mentioned method of collecting different types of waste electrodes through different waste boxes 13 prevents the mixing of different types of waste electrodes, avoids the need to classify the waste electrodes in the process of subsequent processing of the waste electrodes, and thus avoids the reduction in the efficiency of subsequent processing of the waste electrodes.

[0048] Of course, in some other embodiments, the first conveying mechanism 11 and the second conveying mechanism 12 may also adopt other ways of transporting the electrode such as chain transmission, which is not limited here.

[0049] Please refer to Figure 1. In some embodiments, when the second conveying mechanism 12 moves to the first position 121, the second end 113 conveys the electrode to the receiving end 124. Please also refer to Figures 2-5. When the second conveying mechanism 12 moves to the second position 122, the receiving end 124 moves away from the second end 113 and forms a gap with the second end 113.

[0050] It can be understood that the second end 113 of the first conveying mechanism 11 and the receiving end 124 of the second conveying mechanism 12 can be set to a separated state, that is, when the second conveying mechanism 12 is in the first position 121, the receiving end 124 is adjacent to and connected to the second end 113, that is, the pole piece can be conveyed from the second end 113 to the receiving end 124, and when the second conveying mechanism 12 moves from the first position 121 to the second position 122, the receiving end 124 forms a gap with the second end 113 as the second conveying mechanism 12 moves, so that the second end 113 and the receiving end 124 are separated, that is, the pole piece cannot be conveyed from the second end 113 to the receiving end 124.

[0051] In some other embodiments, the receiving end 124 of the second conveying mechanism 12 may be continuously connected to the second end 113 of the first conveying mechanism 11 , that is, the receiving end 124 is not separated from the second end 113 as the second conveying mechanism 12 moves.

[0052] 2 , 3 and 4 , in some embodiments, the second conveying mechanism 12 can move between a first position 121 and a second position 122 along a first direction 2 , where the first direction 2 is perpendicular to the direction from the first end 112 to the second end 113 .

[0053] It can be understood that when the second conveying mechanism 12 is in the first position 121, the direction of conveying the electrode sheets by the first conveying mechanism 11 and the second conveying mechanism 12 can be regarded as the conveying direction of the transport device 1. Other devices can be set at the position of the transport device 1 along the conveying direction to perform subsequent process processing on qualified electrode sheets. In other words, other devices can be set on the side of the second conveying mechanism 12 away from the first conveying mechanism 11 to perform subsequent process processing on qualified electrode sheets conveyed by the second conveying mechanism 12. Of course, other conveying mechanisms can be set on the side of the second conveying mechanism 12 away from the first conveying mechanism 11, which is not limited here.

[0054] Therefore, the second position 122 is set in the first direction 2 of the first position 121, so that the second conveying mechanism 12 moves between the first position 121 and the second position 122 along the first direction 2, that is, the second conveying mechanism 12 is set to move in the first direction 2 perpendicular to the first end 112 toward the second end 113, which not only forms a gap and separation between the receiving end 124 and the second end 113, but also avoids the movement path of the second conveying mechanism 12 from affecting the first conveying mechanism 11 and the device arranged on the side of the second conveying mechanism 12 away from the first conveying mechanism 11.

[0055] In some other embodiments, the second conveying mechanism 12 may also move along the conveying direction, that is, move from the first end 112 toward the second end 113. Of course, the second conveying mechanism 12 may also move along other conveying directions, which are not limited here.

[0056] Please refer to FIG. 2 again. In the first embodiment, when the second conveying mechanism 12 is located at the second position 122 , the electrode is output from the second end 113 through the gap to the waste box 13 .

[0057] Exemplarily, the second position 122 can be set to be in the positive direction 21 of the first direction 2 at the first position 121. When the second conveying mechanism 12 is located at the second position 122, a gap for the electrode to pass through is formed between the second end 113 and the receiving end 124. At this time, the waste box 13 can be set to be in the opposite direction 22 of the first direction 2 at the first position 121.

[0058] It can be understood that in order to ensure the stability of the electrode during transportation, that is, to prevent the electrode from being offset or even detached from the vacuum belt 114 during transportation by the vacuum belt 114, the direction of the first end 112 toward the second end 113 can be horizontal, and the first direction 2 is a vertical direction. At this time, the second position 122 is located above the first position 121, and the waste box 13 is arranged on the second conveying mechanism 12 below the first position 121.

[0059] At this time, in the process of transporting the scrap electrode through the gap to the scrap box 13 at the second end 113, the scrap electrode can be allowed to fall freely into the scrap box 13 under the action of gravity. In other words, when the second end 113 transports the scrap electrode through the gap, the scrap electrode can be separated from the second end 113 and fall freely under the action of gravity. At the same time, the scrap box 13 is set on the falling path of the scrap electrode, so that the scrap electrode falls into the scrap box 13 after passing through the gap.

[0060] It is understood that in order to enable the waste bin 13 to collect waste electrodes according to different categories, the waste bin 13 can include a first waste bin 131 and a second waste bin 132. The first waste bin 131 is used to recycle waste electrodes with surface defects, and the second waste bin 132 is used to recycle waste electrodes with size defects. The second waste bin 132 is set on the falling path of the waste electrodes, and the first waste bin 131 is movably set above the second waste bin 132, and the falling path of the waste electrodes intersects with the movement path of the first waste bin 131. When the scrap electrode is detected as a scrap electrode with surface defects, the first scrap box 131 moves to the falling path of the scrap electrode, so that the scrap electrode with surface defects falls into the first scrap box 131; when the scrap electrode is detected as a scrap electrode with size defects, the first scrap box 131 moves to other positions of the movement path, so that the scrap electrode with size defects falls into the second scrap box 132.

[0061] Of course, an intermediate conveying mechanism may also be used for transportation, that is, the second end 113 transports the waste electrode to the intermediate conveying mechanism, and the intermediate conveying mechanism transports the waste electrode to the waste box 13, which is not limited here.

[0062] Please refer to FIG. 3 again. In the second embodiment, when the second conveying mechanism 12 is located at the second position 122 , the electrode is conveyed from the second end 113 to the second conveying surface 123 and output to the waste bin 13 from the conveying end 125 .

[0063] Exemplarily, the second position 122 can be set in the opposite direction 22 of the first direction 2 at the first position 121, and the waste box 13 can be set on the side of the second conveying mechanism 12 at the second position 122 away from the first conveying mechanism 11.

[0064] When the electrode piece located at the first conveying mechanism 11 is detected as a scrap electrode piece, the second conveying mechanism 12 moves from the first position 121 to the second position 122 along the opposite direction 22 of the first direction 2, so that a gap is formed between the receiving end 124 and the second end 113. At this time, although a gap is formed between the second end 113 and the receiving end 124, the scrap electrode piece does not pass through the gap when it is output from the second end 113. Instead, it is output from the second end 113 to the second conveying surface 123, and the second conveying surface 123 outputs the scrap electrode piece from the conveying end 125 to the waste bin 13 along its own conveying direction. It should be noted that the detection result of the electrode piece located at the first conveying mechanism 11 may show that there are both scrap electrode pieces and qualified electrode pieces. When the qualified electrode moves to the conveying end 125, the second conveying mechanism 12 is located at the first position 121, and the qualified electrode continues to be conveyed from the conveying end 125 to the subsequent process for subsequent processing; when the waste electrode moves to the conveying end 125, the first conveying mechanism 11 and the second conveying mechanism 12 both suspend conveying. After the second conveying mechanism 12 moves from the first position 121 to the second position 122, the second conveying mechanism 12 continues to convey the waste electrode, so that the waste electrode is output from the conveying end 125 to the waste box 13.

[0065] Similarly, the second end 113 outputs the scrap electrode to the second conveying surface 123, and the conveying end 125 outputs the scrap electrode to the waste box 13 by free fall or by using an intermediate conveying mechanism, which will not be described in detail here.

[0066] Please refer to FIG. 4 . In the third embodiment, when the second conveying mechanism 12 is located at the second position 122 , the electrode is conveyed from the second end 113 to the second conveying surface 123 and output to the waste bin 13 from the receiving end 124 .

[0067] Exemplarily, when the second position 122 is set to be in the opposite direction 22 of the first direction 2 along the first direction 2 at the first position 121, the waste box 13 can be set on the side of the second conveying mechanism 12 close to the first conveying mechanism 11. In other words, the waste box 13 can be set on the side of the receiving end 124 away from the conveying end 125.

[0068] After the scrap electrode pieces are output from the second end 113 to the second conveying surface 123, the motor can be reversed to change the conveying direction of the second conveying surface 123. That is, in the conveying mode, the conveying direction of the second conveying surface 123 is from the receiving end 124 to the conveying end 125. In the waste discharge mode, after the motor is reversed, the conveying direction of the second conveying surface 123 is from the conveying end 125 to the receiving end 124. At this time, the second conveying surface 123 outputs the scrap electrode pieces from the receiving end 124 to the waste bin 13 along the changed conveying direction.

[0069] Similarly, the second end 113 outputs the scrap electrode to the second conveying surface 123, and the receiving end 124 outputs the scrap electrode to the waste box 13 by free fall or by using an intermediate conveying mechanism, which will not be elaborated here.

[0070] Please refer to Figure 5. In some more specific embodiments, the second conveying mechanism 12 is rotatably arranged downstream of the first conveying mechanism 11. When the second conveying mechanism 12 rotates to the second position 122, the electrode located at the first conveying mechanism 11 is conveyed from the second end 113 through the gap to the waste box 13, and the electrode located at the second conveying mechanism 12 is output from the conveying end 125 to the waste box 13.

[0071] In this embodiment, to create a gap between the second end 113 and the receiving end 124 when the second conveying mechanism 12 rotates from the first position 121 to the second position 122, the rotation axis of the second conveying mechanism 12 can be positioned on a side of the receiving end 124 away from the second end 113. Furthermore, the waste bin 13 can be positioned on one side of the second end 113 and the conveying end 125.

[0072] The rotation axis of the second conveying mechanism 12 is set at a position of the receiving end 124 away from the second end 113, which ensures that a gap is formed between the receiving end 124 and the second end 113 when the second conveying mechanism 12 rotates to the second position 122. It should be noted that if other devices are set on the side of the conveying end 125 away from the receiving end 124, then when the second conveying mechanism 12 rotates to the second position 122, a gap may also be formed between the conveying end 125 and the other devices. When the second conveying mechanism 12 rotates to the second position 122, the scrap electrode pieces located at the first conveying mechanism 11 are output from the second end 113 through the gap to the waste bin 13, and the scrap electrode pieces located at the second conveying mechanism 12 are output from the conveying end 125 through the gap to the waste bin 13.

[0073] Configuring the second conveyor mechanism 12 to rotate can reduce the space occupied by the second conveyor mechanism 12 during movement and reduce the complexity of the structural design. Furthermore, both the first conveyor mechanism 11 and the second conveyor mechanism 12 can convey the scrap electrode pieces through corresponding gaps or intervals to the scrap bin 13, further improving the accuracy and comprehensiveness of waste removal and preventing the scrap electrode pieces from being transported to subsequent processes by the second conveyor mechanism 12.

[0074] In other more specific embodiments, after the waste electrode located on the first conveying mechanism 11 is conveyed to the second conveying mechanism 12, the second conveying mechanism 12 rotates to the second position 122. At this time, the second conveying mechanism 12 uses motor reversal to change the conveying direction of the second conveying surface 123, so that the waste electrode located on the first conveying surface 111 is output from the second end 113 to the second conveying surface 123, and output from the receiving end 124 to the waste box 13. At the same time, the waste electrode located on the second conveying surface 123 is directly output from the receiving end 124 to the waste box 13.

[0075] Please refer to Figure 6. In other embodiments, the second conveying mechanism 12 is rotatably disposed on the side of the second end 113 away from the first end 112; the waste box 13 is disposed on the side of the conveying end 125 away from the receiving end 124. When the second conveying mechanism 12 rotates to the second position 122 (not shown in the figure), the waste electrode is conveyed from the second end 113 to the receiving end 124, and then conveyed to the waste box 13 through the conveying end 125.

[0076] Exemplarily, the receiving end 124 is connected to the second end 113. In other words, after the second conveying mechanism 12 rotates to the second position 122, the electrode piece can also be transported to the receiving end 124 via the second end 113. For example, the receiving end 124 and the second end 113 can be connected by a rotating shaft, and the rotation axis of the second conveying mechanism 12 is set at the receiving end 124, so that when the second conveying mechanism 12 rotates from the first position 121 to the second position 122, the receiving end 124 and the second end 113 are continuously connected. In other words, there is no gap or partition between the receiving end 124 and the second end 113. When the second conveying mechanism 12 moves to the second position 122, the waste electrode piece is transported by the first conveying mechanism 11 to the conveying end 125 of the second conveying mechanism 12, and then transported by the conveying end 125 to the waste bin 13. It is understood that when other devices are installed on the side of the second conveying mechanism 12 away from the first conveying mechanism 11, when the second conveying mechanism 12 rotates to the second position 122, a gap may be created between the conveying end 125 and the other devices. At this time, the conveying end 125 conveys the waste electrode pieces through the gap into the waste bin 13. Similarly, the waste electrode pieces at the conveying end 125 can fall into the waste bin 13 by free fall, or an intermediate conveying mechanism can be installed in the gap to convey the waste electrode pieces into the waste bin 13 through the intermediate conveying mechanism, which will not be described in detail here. Of course, the receiving end 124 can also not overlap with the second end 113, which is not limited here.

[0077] In some other embodiments, the second conveying mechanism 12 has other movement modes to form a gap between the second end 113 and the receiving end 124, which is not limited here.

[0078] 6 , in some more specific embodiments, the first conveying mechanism 11 and the second conveying mechanism 12 share a vacuum belt 114 .

[0079] The first conveying mechanism 11 and the second conveying mechanism 12 use the same vacuum belt 114 to convey the electrode pieces, which can ensure that the electrode pieces can be conveyed from the first conveying mechanism 11 to the second conveying mechanism 12 after the second conveying mechanism 12 rotates to the second position 122 .

[0080] In some other more specific embodiments, the vacuum belts 114 of the first conveying mechanism 11 and the vacuum belts 114 of the second conveying mechanism 12 may each be a single vacuum belt 114 .

[0081] Please continue to refer to FIG. 6 . In some more specific embodiments, a tension adjustment component 14 is further included. The tension adjustment component 14 is connected to the vacuum belt 114 to adjust the tension of the vacuum belt 114 .

[0082] The tension adjustment assembly 14 is used to adjust the tension of the vacuum belt 114 to prevent the vacuum belt 114 from slipping and affecting the conveying efficiency of the transport device 1 .

[0083] In some other more specific embodiments, the distance between the rotating shafts around which the vacuum belt 114 is wound may also be adjusted to adjust the tension of the vacuum belt 114 .

[0084] Please continue to refer to Figure 6. In some embodiments, the tension adjustment component 14 includes a bracket 141 and a moving component 142; the moving component 142 is movably disposed on the bracket 141, and the vacuum belt 114 is connected to the moving component 142. When the moving component 142 moves, it adjusts the tension of the vacuum belt 114.

[0085] The bracket 141 may be provided on the second conveying mechanism 12 or independently provided.

[0086] The moving assembly 142 is mounted on the bracket 141, and the vacuum belt 114 is connected to the moving assembly 142. When the moving assembly 142 moves, it can drive the vacuum belt 114 to move, thereby adjusting the tension of the vacuum belt 114. For example, the moving direction of the moving assembly 142 is perpendicular to the surface of the vacuum belt 114. In other words, the moving direction of the moving assembly 142 is perpendicular to the transport direction of the vacuum belt 114, thereby adjusting the tension of the vacuum belt 114 in the transport direction.

[0087] In other embodiments, the tension adjustment assembly 14 may be a rotating shaft around which the vacuum belt 114 is wound, and the tension of the vacuum belt 114 is adjusted by adjusting the distance between the rotating shafts.

[0088] Please continue to refer to Figure 6. In some more specific embodiments, the moving component 142 includes a mounting block 1421 and a control roller 1422. The mounting block 1421 is movably disposed on the bracket 141; the control roller 1422 is connected to the mounting block 1421, and the vacuum belt 114 is connected to the control roller 1422. The mounting block 1421 drives the control roller 1422 to move to adjust the tension of the vacuum belt 114.

[0089] The control roller 1422 is connected to the mounting block 1421 , and the mounting block 1421 is moved to be set on the bracket 141 . The mounting block 1421 moves on the bracket 141 to drive the control roller 1422 to move, thereby driving the vacuum belt 114 to move, so as to adjust the tension of the vacuum belt 114 .

[0090] In some other more specific embodiments, a slide groove may be provided on the bracket 141 , the control roller 1422 may be slidably provided in the slide groove, and the control roller 1422 may move along the slide groove.

[0091] Please continue to refer to FIG. 6 . In some more specific embodiments, the moving assembly 142 further includes an elastic member 1423 . The elastic member 1423 is connected between the mounting block 1421 and the bracket 141 to drive the mounting block 1421 to move.

[0092] The elastic member 1423 is used to apply a force to the mounting block 1421 to drive the mounting block 1421 to move, thereby driving the control roller 1422 to move, and thus driving the vacuum belt 114 to move, thereby adjusting the tension of the vacuum belt 114. Alternatively, the elastic member 1423 can be configured as a spring, one end of which is connected to the bracket 141 and the other end is connected to the mounting block 1421. The spring is continuously compressed, thereby applying an elastic force to the mounting block 1421. The mounting block 1421 moves under the action of the elastic force to adjust the tension of the vacuum belt 114.

[0093] In other more specific embodiments, the position of the mounting block 1421 may be manually adjusted to drive the control roller 1422 to move, thereby achieving the purpose of adjusting the tension of the vacuum belt 114 .

[0094] Please refer to Figure 1 again. In the embodiment of the present disclosure, a third conveying mechanism 15 is further included. The third conveying mechanism 15 is arranged on a side of the second conveying mechanism 12 in the first position 121 away from the first conveying mechanism 11, and when the second conveying mechanism 12 moves to the first position 121, the conveying end 125 conveys the electrode to the third conveying mechanism 15.

[0095] The second conveying mechanism 12 conveys the qualified electrode pieces to the third conveying mechanism 15, and the third conveying mechanism 15 conveys the qualified electrode pieces to the subsequent process for subsequent processing. The third conveying mechanism 15 is provided to convey the qualified electrode pieces, which can avoid the inaccurate transmission accuracy caused by the position deviation after the second conveying mechanism 12 moves from the second position 122 to the first position 121, thereby affecting the subsequent process processing effect.

[0096] The present disclosure also provides a lamination device (not shown in the figure), including the above-mentioned transport device 1. While providing the functions of transporting qualified electrodes and removing waste electrodes, the above-mentioned transport device 1 eliminates the problem of material blockage in the transport device 1, thereby improving the efficiency of removing waste electrodes and improving the efficiency of transporting qualified electrodes, thereby improving the efficiency of the lamination device in processing the electrodes. In addition, eliminating the problem of material blockage in the transport device 1 can extend the service life of the transport device 1 and the lamination device.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
