Description

Technical Field

[0001] This utility model relates to the field of battery cell conveying technology, and in particular to a battery cell moving device. Background Technology

[0002] A whole solar cell is the initial raw material form, usually a large, complete substrate; a split wafer is an intermediate form formed after the whole cell has been initially cut, such as photovoltaic silicon wafer split wafers, glass substrate split wafers, semiconductor chip split wafers, etc. In the production and processing of these, special equipment is needed to realize the material transportation and position adjustment in order to connect upstream and downstream processes such as cutting, testing, and packaging.

[0003] Existing sheet-moving devices are incompatible with both sheet-breaking and whole-sheet states. While sheet-breaking retains the outline of a whole sheet, its structural strength is lower than that of a whole sheet due to the presence of internal cutting seams. Furthermore, it is crucial to prevent premature separation or damage to the sheet-breaking unit caused by stress on the cutting seams during transport. Existing equipment uses a wide single conveyor belt adapted to whole sheets, which is prone to cracking at the cutting seams due to uneven local pressure when transporting sheet-breaking. Alternatively, using a narrow conveyor belt adapted to sheet-breaking can lead to sagging in the middle due to insufficient support points when the sheet-breaking is laid across, causing misalignment of the cutting seams. Moreover, the lack of alternating conveying functionality results in low continuous production efficiency, with a single conveyor system transporting the sheet back and forth between upstream and downstream, leading to long waiting times for both upstream and downstream components. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problems of existing battery cell conveying devices being unable to simultaneously adapt to whole and half battery cells, lacking alternating conveying function, resulting in low continuous production efficiency, and having to transport the cells back and forth between upstream and downstream by a set of conveying mechanisms, leading to long waiting times and reduced production capacity. Thus, a battery cell moving device is provided.

[0005] To solve the above-mentioned technical problems, this utility model provides a battery cell moving device, comprising: A conveying mechanism includes: a first driving member, a conveying frame, and a conveyor belt, wherein the conveyor belt is rotatably mounted on the conveying frame, the output end of the first driving member is connected to the conveyor belt, and there are at least two conveyor belts arranged at intervals. A moving mechanism includes: a moving frame, a drive assembly, and a support member. The moving frame is disposed at the output end of the conveyor belt, and the support member is connected to the output end of the drive assembly. The drive assembly is used to drive the support member to move along the height direction and / or length direction of the moving frame. There are at least two sets of drive assemblies and support members, which are respectively located on both sides of the width direction of the moving frame. The support member is provided with a protrusion, and the width of the protrusion is not greater than the spacing between adjacent conveyor belts.

[0006] In one embodiment of the present invention, the conveyor belt and the moving frame have alternating spaces along the height direction, and the height of the alternating spaces is at least twice the thickness of the support member.

[0007] In one embodiment of this utility model, the first driving member is a rotary driving member and the output shaft is fixedly connected to a first synchronous pulley. One end of the conveyor frame is rotatably connected to a driving shaft. The other ends of the driving shaft and the conveyor belt are respectively fixedly connected to at least two driving pulleys and a corresponding number of driven pulleys. The driving shaft is fixedly sleeved with a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are sleeved with a first synchronous belt.

[0008] In one embodiment of the present invention, the number of driving wheels and driven wheels is configured to be at least two sets, each set having two driving wheels and driven wheels spaced apart, and each corresponding driving wheel and driven wheel is fitted with a conveyor belt.

[0009] In one embodiment of this utility model, the support member is a support plate, the protrusion is disposed on the side of the support plate near the conveyor belt, the length direction of the protrusion is parallel to that of the first synchronous belt, the width of the protrusion is less than the spacing of each set of conveyor belts, the size of each set of conveyor belts is adapted to the diced piece to be conveyed, and the size of two adjacent sets of conveyor belts is adapted to the whole piece to be conveyed.

[0010] In one embodiment of the present invention, the conveying mechanism is provided with a correction component on both sides along its width direction. The correction component includes a second driving member, a bracket, and a guide wheel. The bracket is connected to the output end of the second driving member, and the guide wheel is rotatably connected to the bracket. The second driving member is used to drive the bracket and the guide wheel to move along the width direction of the conveying mechanism.

[0011] In one embodiment of the present invention, the driving component includes a third driving member and a fourth driving member. The third driving member is capable of driving along the length direction of the moving frame, the fourth driving member is connected to the output end of the third driving member and is capable of moving along the height direction of the moving frame, and the support member is connected to the output end of the fourth driving member.

[0012] In one embodiment of this utility model, the conveyor frame is further provided with a receiving bin, the top surface of which is not higher than the bottom surface of the conveyor belt relative to the ground.

[0013] In one embodiment of the present invention, the second driving component includes: a drive motor, and a third synchronous pulley and a fourth synchronous pulley respectively rotatably connected to both sides of the conveyor frame along the width direction. A second synchronous belt is sleeved between the third synchronous pulley and the fourth synchronous pulley, and the bracket is connected to one side of the second synchronous belt.

[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects: The battery cell moving device described in this utility model utilizes a structure with at least two conveyor belts spaced apart. For whole sheets of material, their wide width allows for stable load-bearing by straddling adjacent conveyor belts. Multiple conveyor belts share the weight of the entire sheet, avoiding localized stress concentration that can easily occur when a single conveyor belt supports wide materials, and preventing deformation or damage to the entire sheet due to uneven stress. For cleaved materials, the width of a single conveyor belt can be precisely matched to the size of the cleaved material. The cleaved material is placed independently on a single conveyor belt, eliminating concerns about positional shifts caused by excessively wide conveyor belts. The drive assembly and support components consist of at least two sets, located on opposite sides of the moving frame's width. Together with the support components, they enable alternating conveying, better connecting upstream and downstream components and reducing waiting time. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example

[0020] Reference Figures 1-8 As shown, this utility model discloses a battery cell moving device. include: The conveying mechanism 5 includes: a first driving member 58, a conveying frame 1 and a conveyor belt 55. The conveyor belt 55 is rotatably disposed on the conveying frame 1. The output end of the first driving member 58 is connected to the conveyor belt 55. There are at least two conveyor belts 55 and they are spaced apart. The moving mechanism includes a moving frame, a drive assembly 2, and a support member 3. The moving frame is disposed at the output end of the conveyor belt 55, and the support member 3 is connected to the output end of the drive assembly 2. The drive assembly 2 is used to drive the support member 3 to move along the height direction and / or length direction of the moving frame. There are at least two sets of drive assemblies 2 and support members 3, which are respectively located on both sides of the width direction of the moving frame. The support member 3 is provided with a protrusion 32, and the width of the protrusion 32 is not greater than the spacing between adjacent conveyor belts 55.

[0021] The present invention discloses a cell 7 moving device. When the cell cleaving moving platform is started, the first driving component 58 drives the conveyor belt 55 to rotate cyclically along the length of the conveyor frame 1. The operator or automated feeding equipment places the work to be processed, i.e., cleaved or whole cells, on the conveyor belt 55. During the rotation, the conveyor belt 55 carries the work to be processed from the feed end to the output end of the conveyor frame 1. When the work to be processed moves to the output end of the conveyor belt 55, the driving component 2 drives the support component 3 to rise along the height direction of the moving frame, so that the protrusion 32 of the support component 3 extends into the gap between adjacent conveyor belts 55 until the protrusion 32 contacts the bottom surface of the work to be processed and stably lifts it. After the work to be processed is lifted, the driving component 2 continues to drive the support component 3 to move along the length direction of the moving frame, transferring the work to be processed to a subsequent designated station, such as a cell cleaving processing station or an inspection station.

[0022] The conveyor belt 55 and the movable frame have alternating spaces along the height direction, and the height of the alternating spaces is at least twice the thickness of the support member. During the rising process, a sufficient gap is maintained between the top surface of the support member and the bottom surface of the conveyor belt 55 to avoid collision. When the support member rises to a preset height, i.e., when the protrusion 32 contacts the material, the main body of the support member remains within the alternating space; only the protrusion 32 of the support member 3 passes through the gap in the conveyor belt 55 and acts on the material, ensuring safety during the rising process. The height of the protrusion 32 itself is also greater than the structural height of the conveyor belt 55 and its frame. Figure 2 The four support members 3 are a schematic diagram of the reachable position, but in reality only two support members 3 are needed.

[0023] Reference Figure 3 As shown, the first driving member 58 is a rotary driving member and the output shaft is fixedly connected to the first synchronous pulley 57. One end of the conveyor frame 1 is rotatably connected to the driving shaft 53. The other end of the driving shaft 53 and the conveyor belt 55 are respectively fixedly connected to at least two driving pulleys 56 and a corresponding number of driven pulleys 51. The driving shaft 53 is fixedly sleeved with the second synchronous pulley 52. ​​The first synchronous pulley 57 and the second synchronous pulley 52 are sleeved with the first synchronous belt 59.

[0024] The first driving member 58, i.e., the rotary driving member, drives the first synchronous pulley 57, which is fixedly connected to it, to rotate synchronously. Since the first synchronous belt 59 and the first synchronous pulley 57 mesh with each other through tooth grooves, the rotational power of the first synchronous pulley 57 is transmitted to the first synchronous belt 59 through tooth surface contact, causing the first synchronous belt 59 to make a circular motion along the direction of the synchronous pulley groove; at the same time, the first synchronous belt 59 meshes with the second synchronous pulley 52 through the tooth groove on the other side, thereby driving the second synchronous pulley 52 to rotate synchronously around the axis of the drive shaft 53.

[0025] Because the second synchronous pulley 52 is fixedly connected to the drive shaft 53, the rotation of the second synchronous pulley 52 directly drives the drive shaft 53 to rotate around its own axis. The rotation of the drive shaft 53 synchronously drives all the drive pulleys 56 fixed on it to rotate. The drive pulleys 56 transmit driving force along the conveying direction to the conveyor belt 55 through friction or tooth meshing with the inner side of the conveyor belt 55, so that the conveyor belt 55 moves along the circular path of the drive pulleys 56 and the driven pulleys 51.

[0026] The number of driving wheels 56 and driven wheels 51 is configured to be at least two sets, with two driving wheels 56 and driven wheels 51 in each set, spaced apart. Each corresponding driving wheel 56 and driven wheel 51 is fitted with a conveyor belt 55. When conveying flake-like materials, the flakes are placed individually on a single conveyor belt 55, which provides stable support and conveying for the flakes. When conveying larger whole pieces of material, the whole piece is placed across two or more adjacent conveyor belts 55, with multiple conveyor belts 55 providing support for the whole piece and preventing it from sagging or deforming due to its large size. The material is smoothly conveyed from one end of the conveyor frame 1 to the output end with the synchronous movement of the conveyor belts 55. The spacing of the conveyor belts 55 throughout the process also provides space for the protrusions 32 of the subsequent moving mechanism support member 3 to move. The conveyor belt frame 55 is also equipped with guide wheels 54, which are at the same height as the driven wheels 51, keeping the conveyor belt 55 horizontal.

[0027] Reference Figure 5 As shown, the support member 3 is a support plate 31, and the protrusion 32 is disposed on the side of the support plate 31 near the conveyor belt 55. The protrusion 32 is parallel to the length direction of the first synchronous belt 59. The width of the protrusion 32 is smaller than the spacing between each set of conveyor belts 55. The size of each set of conveyor belts 55 is adapted to the fragments to be conveyed, and the size of two adjacent sets of conveyor belts 55 is adapted to the whole pieces to be conveyed. Since the width of the protrusion 32 is smaller than the spacing between adjacent conveyor belts 55, the protrusion 32 on the support plate 31 can smoothly extend into the gap between adjacent conveyor belts 55. The drive assembly 2 drives the support plate 31 to rise in the height direction, and the protrusion 32 contacts the bottom surface of the fragment and lifts the whole piece or fragment battery cell 7 away from the surface of the conveyor belt 55.

[0028] Reference Figure 4As shown, the conveying mechanism 5 has a alignment component 6 on each side along its width direction. The alignment component 6 includes a second drive member, a bracket 65, and guide wheels 66. The bracket 65 is connected to the output end of the second drive member, and the guide wheels 66 are rotatably connected to the bracket 65. The second drive member drives the bracket 65 and guide wheels 66 to move along the width direction of the conveying mechanism 5. Before material conveying, the initial position of the alignment component 6 is preset according to the material width: the second drive member drives the bracket 65 and guide wheels 66 to move towards the conveying center axis, making the distance between the two guide wheels 66 slightly greater than the material width, reserving space for material placement. When the material starts to be conveyed with the conveyor belt 55, if the material shifts to one side due to placement deviation or vibration of the conveyor belt 55, it will contact the guide wheel 66 on that side. Since the guide wheel 66 can rotate flexibly, the sliding friction between the material and the guide wheel 66 is converted into rolling friction of the guide wheel 66, preventing scratches on the material surface. Simultaneously, the position sensor detects a material offset signal and transmits it to the control system. The control system then instructs the second drive component to operate: if the material offsets to the left, the left second drive component drives the left support 65 to adjust slightly away from the conveying center, or the right second drive component drives the right support 65 to move closer to the conveying center. Through the coordinated action of the guide wheels 66 on both sides, the material is pushed back to the conveying center axis position. Once the material is aligned, the position sensor detects that the material is in the center position, and the control system instructs the second drive component to drive the support 65 and guide wheels 66 to reset to their initial positions, awaiting the alignment of the next offset material. For continuously conveyed materials, the alignment component 6 can monitor and correct the position of each material in real time, ensuring that all materials accurately reach the output end of the conveyor belt 55. The specific detection principle uses existing technology, which is not within the scope of protection of this application, and therefore will not be elaborated upon.

[0029] Reference Figures 5-6 As shown, the drive assembly 2 includes a third drive member 21 and a fourth drive member 22. The third drive member 21 can be driven along the length direction of the moving frame, and the fourth drive member 22 is connected to the output end of the third drive member 21 and can move along the height direction of the moving frame. The support member 3 is connected to the output end of the fourth drive member 22.

[0030] The third drive component 21 first drives the connected fourth drive component 22 and support component 3 to move synchronously along the length direction until the protrusion 32 on the support component 3 moves to a position directly below the material. The fourth drive component 22 then drives its output end to move upward along the height direction, causing the support component 3 to rise synchronously and extend into the space between adjacent conveyor belts 55, contacting the bottom surface of the material. The support component 3 lifts the material off the surface of the conveyor belt 55. The third drive component 21 then drives the fourth drive component 22, support component 3, and material to move along the length direction to the target position, at which point the third drive component 21 stops. The output end of the fourth drive component 22 moves downward along the height direction, causing the support component 3 and material to descend, placing the material at the target position, such as a workbench or subsequent conveying mechanism 5. The fourth drive component 22 then stops, completing one material movement process.

[0031] The conveyor frame 1 is also equipped with a receiving bin 4, the top surface of which is no higher than the bottom surface of the conveyor belt 55 relative to the ground. During material conveying, due to material quality issues such as defective products, placement deviations, or vibrations of the conveyor belt 55, some material may fall through the gaps in the conveyor belt 55 or slide off its edge. This fallen material falls directly downwards under gravity and enters the receiving bin 4, preventing it from landing on the ground or other components of the conveyor frame 1.

[0032] Reference Figure 8 As shown, the second driving component includes: a drive motor 62, and a third synchronous pulley and a fourth synchronous pulley that are rotatably connected to both sides of the conveyor frame 1 along the width direction. A second synchronous belt 63 is sleeved between the third synchronous pulley and the fourth synchronous pulley, and the bracket 65 is connected to one side of the second synchronous belt 63.

[0033] The drive motor 62 drives the third synchronous pulley connected to it to rotate around its own axis. The third synchronous pulley, through meshing with the second synchronous belt 63, drives the second synchronous belt 63 to move along a circular path. The second synchronous belt 63 further drives the fourth synchronous pulley to rotate around its own axis. Since the bracket 65 is fixedly connected to one side of the second synchronous belt 63, the movement of the second synchronous belt 63 causes the bracket 65 to move synchronously along the width direction of the moving frame: if the material shifts to the left, the drive motor 62 drives the third synchronous pulley to rotate clockwise, the left side of the second synchronous belt 63 moves upward, driving the left bracket 65 to move towards the conveying center, and the left guide wheel 66 contacts the left side of the material and pushes the material to the right until the material is aligned; if the material shifts to the right, the drive motor 62 reverses, drives the third synchronous pulley to rotate counterclockwise, the right side of the second synchronous belt 63 moves upward, the right bracket 65 moves towards the conveying center, and the right guide wheel 66 pushes the material to the left to the aligned position. Once the material is aligned, the position sensor detects that the material is in the center position. The control system then instructs the drive motor 62 to stop rotating, or, according to a preset program, instructs the drive motor 62 to reverse, causing the bracket 65 and guide wheel 66 to move in the opposite direction along the second synchronous belt 63, resetting to the initial position and awaiting the next alignment action. For continuously conveyed materials, the drive motor 62 can adjust its rotation direction and angle based on the real-time signal from the position sensor to achieve alignment for each material.

[0034] The second synchronous belt 63 is positioned between the ground and the conveyor belt 55. The conveyor frame 1 has a clearance hole 61. A centering arm 64 is fixedly connected to one side of the second synchronous belt 63. The centering arm 64 extends through the clearance hole 61 and is connected to the bracket 65. The bracket 65 is movably connected to the conveyor frame 1 via a sliding pair. The sliding pair includes a slide rail and a slider. Driven by the centering arm 64, the bracket 65 moves closer to or further away from the material along the width direction of the moving frame. The slider moves synchronously with the bracket 65, moving linearly along the guide rail fixed on the moving frame. The guide rail provides strict guidance and constraint on the movement direction of the slider, ensuring that the bracket 65 always moves along the preset linear trajectory without lateral deviation or swaying. At the same time, the low friction characteristics of the sliding pair make the movement of the bracket 65 smoother, avoiding fluctuations in the movement speed of the bracket 65 due to excessive frictional resistance. This ensures that the force exerted when the guide wheel 66 contacts the material is uniform, preventing the material from tilting or being damaged due to uneven force. In this embodiment, the alignment arms 64 on both sides of the conveyor belt 55 are respectively connected to both sides of the second synchronous belt 63 so that the guide wheels 66 on both sides move in opposite directions, that is, synchronously approaching each other or synchronously moving away from each other.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
