[0002] During the production process of photovoltaic cells (such as Topcon cells), various processing steps such as laser processing are required. Among them, the laser processing step usually uses a laser to drill holes or grooves on the surface of the cell (such as a silicon wafer) to penetrate part of the thin film layer (such as the Al2O3 layer, the SiNx layer) and expose the silicon substrate, so that the back electric field can contact the silicon substrate through the holes or grooves on the thin film layer.

[0003] The battery cell processing process involves loading cells into the processing station and unloading cells from the processing station. Currently, this loading and unloading process is usually done manually, which is inefficient and makes it difficult to achieve mass production of battery cells. Utility Model Content

[0033] The battery cell processing process involves loading cells into the processing station and unloading cells from the processing station. Currently, this loading and unloading process is usually done manually, which is inefficient and makes it difficult to achieve mass production of battery cells.

[0034] In order to solve the above problems, the present invention proposes a battery cell transport mechanism that can eliminate manual transfer operations and can accurately transfer at least two battery cells one by one to the corresponding areas in the processing station and the loading and unloading station at the same time, thereby improving the battery cell transport efficiency and overall production efficiency.

[0035] See also Figures 1 to 3 In one embodiment of the present invention, the battery cell transport mechanism includes a rotating arm 1 and a swing arm 3; one end of the rotating arm 1 rotates around a first axis 100 under the drive of a first driving assembly 2; the swing arm 3 is rotatably connected to the other end of the rotating arm 1 around a second axis 200, and the second axis 200 is parallel to the first axis 100; the swing arm 3 is provided with at least two picking parts 301 at intervals, and the picking parts 301 are used to drive the battery cells 5 to transfer between the processing station (not shown in the figure) and the loading and unloading station (not shown in the figure) as the rotating arm 1 rotates.

[0036] In this embodiment, the rotating arm 1 can be used as follows Figure 1 The long arm shown; Figure 2Taking the illustrated orientation as an example, the first axis 100 is positioned at the left end of the pivot arm 1, and the second axis 200 is positioned at the right end of the pivot arm 1. The first drive assembly 2 may include a drive device such as a motor or a pneumatic cylinder, as well as a corresponding reduction mechanism and transmission mechanism. The swing arm 3 is rotatably connected to the pivot arm 1 via a seated bearing. The swing arm 3's rotation angle relative to the pivot arm 1 can be manually adjusted, and once the swing arm 3 is fully rotated, it can be secured at its current angular position using fasteners such as screws, clips, or spring plungers. Alternatively, the swing arm 3 can be driven to rotate by a drive device such as a motor or a pneumatic cylinder, and the self-locking nature of the drive device can secure the fully rotated swing arm 3 at its current angular position. The retrieving portion 301 on the swing arm 3 can secure and transfer the battery cells 5 using methods such as grabbing, clamping, suction, and lifting. These retrieving methods can be accomplished using grippers, pneumatic fingers, clips, suction cups, magnets, hooks, and other devices, without limitation.

[0037] By rotating the swing arm 3 relative to the rotating arm 1, the position adjustment of the material picking part 301 relative to the rotating arm 1 is realized, and the adjustable freedom of the material picking part 301 is increased, so that at least two material picking parts 301 can better adapt to the arrangement position of the storage area for placing battery cells 5 in the processing station and the loading and unloading station through position adjustment, so that the at least two battery cells 5 carried by the at least two material picking parts 301 can be more accurately placed one by one in the storage area in the processing station and the loading and unloading station with the rotation of the rotating arm 1 and the rotation of the swing arm 3.

[0038] It can be seen that the battery cell transport mechanism provided in this embodiment can carry the battery cells 5 between the processing station and the loading and unloading station in an orderly manner through the rotation of the rotating arm 1, thereby eliminating the need for manual transfer operations; at the same time, the material taking parts 301 are provided with at least two, so that more battery cells 5 can be transferred through the material taking parts 301 during each transport operation of the rotating arm 1, and because the material taking parts 301 are provided on the swing arm 3, and the swing arm 3 can rotate relative to the rotating arm 1, the relative rotation of the material taking parts 301 is realized. The position adjustment of the arm 1 increases the adjustable freedom of the material-picking section 301, so that at least two material-picking sections 301 can better adapt to the arrangement position of the accommodation area for placing battery cells 5 in the processing station and the loading and unloading station through position adjustment, so that the at least two battery cells 5 carried by the at least two material-picking sections 301 can be placed more accurately one-to-one in the accommodation area in the processing station and the loading and unloading station as the rotating arm 1 rotates and the swing arm 3 rotates; based on the above settings, the handling efficiency of the battery cells and the overall production efficiency can be jointly improved.

[0039] In the above embodiment, since at least two material-retrieving parts 301 are provided on the rotating arm 1, during the rotation of the rotating arm 1 around the first axis 100, if the positions of the at least two material-retrieving parts 301 relative to the rotating arm 1 remain unchanged, that is, the angle of the swing arm 3 relative to the rotating arm 1 remains unchanged, then the absolute angle of the at least two material-retrieving parts 301 in the entire processing system will continue to change with the rotation of the rotating arm 1. Specifically, Figures 1 to 3 As shown, taking the example of a material taking portion 301 provided at each end of the swing arm 3, when the extension direction of the swing arm 1 is Figure 3 When it is set along the left and right directions in the top-down perspective shown, the extension direction of the swing arm 3 is also set along the left and right directions, and the two material-picking parts 301 are arranged at intervals along the left and right directions; when the rotating arm 1 rotates a certain angle, the extension direction of the rotating arm 1 becomes obliquely upward or obliquely downward. If the angle of the swing arm 3 relative to the rotating arm 1 remains unchanged, the extension direction of the swing arm 3 will also become obliquely upward or obliquely downward as the rotating arm 1 rotates. At this time, the two material-picking parts 301 will become arranged at intervals along the obliquely upward or obliquely downward direction; if the two accommodating areas for accommodating battery cells 5 in each workstation are arranged along the left and right directions, then the two battery cells 5 arranged at intervals along the obliquely upward or obliquely downward direction on the two material-picking parts 301 obviously cannot be placed one-to-one in the two accommodating areas of the corresponding workstation.

[0040] In order to solve the above problems, the following embodiments are proposed:

[0041] Reference Figures 1 to 3 The battery cell transport mechanism also includes a second drive component 4, which is connected to the swing arm 3; when the first drive component 2 drives the rotating arm 1 to rotate, the second drive component 4 synchronously drives the swing arm 3 to rotate relative to the rotating arm 1.

[0042] Illustratively, the first axis 100 and the second axis 200 can be set perpendicular to the ground, and the processing stations and loading and unloading stations can be arranged at intervals around the rotating arm 1 on the horizontal plane, so that the rotating arm 1 can make the material picking part 301 reach each station along the circumferential direction through a simple rotation action, thereby simplifying the structure.

[0043] In this embodiment, by providing a second drive assembly 4, the swing arm 3 can be driven to rotate around the second axis 200 in real time while the arm 1 rotates around the first axis 100, thereby achieving real-time adjustment of the angle of the swing arm 3 relative to the arm 1, so that the absolute angle of at least two material-picking portions 301 in the laser processing system is not affected by the rotation of the arm 1. Therefore, when the arm 1 rotates to the corresponding workstation, it can be ensured that at least two material-picking portions 301 can rotate with the swing arm 3 to positions corresponding to at least two accommodating areas in the corresponding workstation, so that at least two battery cells 5 on the swing arm 3 can be accurately placed in the corresponding accommodating areas; moreover, the arrangement direction of each accommodating area in each workstation can be uniformly set, for example, it can be set to be arranged in the left-right direction, without the need for differentiated adjustment according to the different rotation angles of the arm 1. Based on the above arrangement, the accuracy of the battery cell transfer operation and the applicability of the processing system are improved.

[0044] Among them, the second drive assembly 4 may include a drive device such as a motor, a cylinder, and a matching reduction mechanism and a transmission mechanism. The first drive assembly 2 and the second drive assembly 4 can be electrically connected to the same main control module to uniformly control the rotation angle, rotation node, speed and other parameters of the first drive assembly 2 and the second drive assembly 4 through a preset program in the main control module, so that the rotation action of the first drive assembly 2 can be coordinated with the rotation action of the second drive assembly 4. Preferably, the action of the second drive assembly 4 driving the swing arm 3 to rotate should be completed before or at the same time as the action of the first drive assembly 2 driving the rotating arm 1 to rotate is completed, so as to avoid wasting time waiting for the swing arm 3 to rotate into place after the rotating arm 1 rotates into place, thereby further improving the processing and production efficiency of the battery cell.

[0045] Optionally, refer to Figures 1 to 3 The first driving assembly 2 includes a first motor 201 and a first reduction gear 202; the driving end of the first motor 201 is connected to the input end of the first reduction gear 202, and the output end of the first reduction gear 202 is connected to one end of the rotating arm 1.

[0046] Optionally, refer to Figures 1 to 3 The second driving assembly 4 includes a second motor 401 and a second reduction gear 402 ; the driving end of the second motor 401 is connected to the input end of the second reduction gear 402 , and the output end of the second reduction gear 402 is connected to the swing arm 3 .

[0047] Specifically, by providing the first deceleration device 202 and the second deceleration device 402, the rotation speed of the first motor 201 and the second motor 401 can be reduced and the torque can be increased, so that the rotating arm 1 and the swing arm 3 can rotate stably in a preset manner under load. Figure 1As shown, one end of the swing arm 3 is directly installed on the rotating arm 1, and there is no need to install the second motor 401 at the rotation center of the rotating arm 1 and transmit the power through a transmission member such as a belt, thereby improving the driving accuracy and stability in a direct drive manner.

[0048] Optionally, refer to Figures 1 to 3 The second reduction gear 402 includes a planetary reducer; the planetary reducer has the advantages of light weight, small size, wide transmission ratio range, and smooth transmission. It can avoid that the end of the rotating arm 1 used to set the swing arm 3 occupies too much space and interferes with other devices during rotation, and can also avoid the problem of difficulty in rotating the rotating arm 1 due to its excessive weight.

[0049] Optionally, refer to Figures 1 to 3 The picking portion 301 is configured as a picking suction cup; the picking suction cup can realize the picking operation of the battery cell 5 by negative pressure suction. The negative pressure suction method can minimize the rigid collision and scratches caused to the battery cell 5 during the picking process, thereby avoiding damage to the battery cell 5 and affecting its performance to the greatest extent.

[0050] Optionally, refer to Figures 1 to 3 The material removal suction cup adopts a Bernoulli suction cup; the Bernoulli suction cup can transfer the battery cell 5 without directly contacting the surface of the battery cell 5, thereby reducing the physical damage and pollution caused to the surface of the battery cell 5; in addition, the Bernoulli suction cup can accurately control the position of the battery cell 5, and does not require the surface of the battery cell 5 to be completely flat. Even if the surface of the battery cell 5 has a certain degree of roughness or irregularity, the Bernoulli suction cup can also effectively complete the material removal and transfer operations.

[0051] Optionally, refer to Figures 1 to 3 The material taking suction cup is movably connected to the swing arm 3 along a first path, and the first path is parallel to the first axis 100.

[0052] Specifically, the first path can be set to the direction in which the material suction cup sucks the battery cell 5, such as Figure 2 As shown, taking the first axis 100, the second axis 200, and the direction in which the material picking suction cup sucks the battery cell 5 are all perpendicular to the horizontal plane as an example, the material picking suction cup can be slidably fitted on the swing arm 3 in a direction perpendicular to the horizontal plane by means of an axis hole fitting. For example, a guide rod 8 can be provided on the material picking suction cup, and a connecting hole fitting with the guide rod 8 can be provided on the swing arm 3. In this way, the height of the material picking suction cup can be adjusted according to the height of the battery cell in the processing station and the loading and unloading station, so that the suction distance between the material picking suction cup and the battery cell 5 is optimized to improve the accuracy and stability of material picking; when the height of the material picking suction cup is adjusted, a clamp structure 9 can be fixed at the corresponding position on the guide rod 8 of the material picking suction cup, and the clamp structure 9 can be mounted on the swing arm 3, so that the relative height of the material picking suction cup and the swing arm 3 can be kept stable under the action of gravity.

[0053] Optionally, refer to Figures 1 to 3 , also includes an elastic buffer 7, which is arranged between the material picking suction cup and the swing arm 3. The elastic buffer 7 is used to prevent the material picking suction cup from moving toward the swing arm 3 under the elastic force.

[0054] Specifically, based on Figure 1 and Figure 2 In the illustrated arrangement between the retrieving suction cup and the swing arm 3, the elastic buffer 7 can be sleeved on the guide rod 8 of the retrieving suction cup or spaced apart from the guide rod 8. The upper end of the elastic buffer 7 abuts the swing arm 3, and the lower end of the elastic buffer 7 abuts the retrieving suction cup. This prevents the retrieving suction cup from significantly moving upwards due to the elastic force of the elastic buffer 7, and also provides a certain buffering and protective effect for the retrieving suction cup due to the elastic force of the elastic buffer 7. The elastic buffer 7 can be a spring, an elastic colloid, or the like, which is not limited herein.

[0055] Optionally, refer to Figures 1 to 3 , also includes a fixed base 6 and a sensing device 10; one end of the rotating arm 1 is rotatably connected to the fixed base 6 around a first axis 100, and the sensing device 10 is arranged in a preset area of ​​the fixed base 6. The sensing device 10 is used to output a trigger signal to the outside when it detects that the rotating arm 1 rotates to the preset area.

[0056] Specifically, the sensing device 10 includes, but is not limited to, a distance sensor, a proximity switch, a through-beam photoelectric sensor, an image sensor, and the like. Taking a proximity switch as an example, the proximity switch can detect whether a corresponding object exists within a preset range centered on its installation location. Specifically in this embodiment, the proximity switch can output a trigger signal upon detecting that the rotating arm 1 enters a preset area. Taking a through-beam photoelectric sensor as an example, the transmitting end of the through-beam photoelectric sensor is used to emit a target beam to the receiving end. When the target beam is detected to be blocked, it can be determined that there is an obstruction between the transmitting end and the receiving end. Specifically in this embodiment, a detection piece can be provided at a corresponding position on the rotating arm 1. When the rotating arm 1 rotates to the preset area, the detection piece blocks the transmitting end and the receiving end of the through-beam photoelectric sensor, at which point the through-beam photoelectric sensor outputs a trigger signal.

[0057] It is understandable that the trigger signal output by the sensor device 10 may include a prompt signal for interacting with an operator, a high-level or low-level signal for interacting with other devices, etc. Among them, taking the output of a prompt signal by the sensor device 10 as an example, the sensor device 10 may be electrically connected to the prompt device. When the sensor device 10 outputs a trigger signal to the prompt device, the prompt device may send a prompt or alarm signal to the operator in the form of sound, light, image, text, etc., to help the operator determine whether the rotating arm 1 is rotated to the preset area in a preset manner, whether there is a fault in the rotation process, etc., so that the operator can intervene and handle the problem in time when the battery cell transport mechanism operates abnormally; and taking the output of a high-level or low-level signal by the sensor device 10 as an example, the sensor device 10 may communicate with other devices such as the first drive component 2 and the second drive component 4 through the main control module. The electrical connection is set. When the sensor device 10 outputs a trigger signal to the main control module, the on-off action of the relevant branch in the main control module can be triggered based on the on-off characteristics of electronic components such as field effect transistors, thereby triggering the main control module to output a corresponding drive signal to the corresponding device to directly control the device to perform a corresponding operation. For example, when the rotation of the rotating arm 1 is abnormal, the first drive component 2 can be directly controlled to stop driving the rotating arm 1 to rotate, and so on. In actual application, the type of trigger signal output by the sensor device 10, the interaction relationship between the sensor device 10 and the operator and other devices can be flexibly set according to needs, and are not limited here.

[0058] Through the autonomous detection of the sensor device 10, the real-time operating status of the rotating arm 1 can be better controlled, so that when an abnormal situation occurs, timely intervention and processing can be carried out manually or automatically, thereby improving the operating stability and reliability of the battery cell handling mechanism.

[0059] See also Figures 1 to 3 The present invention also proposes a cell processing system, including the cell transport mechanism of any of the above embodiments; the cell processing system may also be provided with processing equipment such as a laser and loading and unloading devices such as a conveying platform, wherein the loading device can continuously supply the cell 5 to be processed into the loading station, so that the cell transport mechanism can transfer the cell 5 in the loading station to the processing station by rotating the rotating arm 1, and the processing equipment can perform corresponding processing operations on the cell 5 entering the processing station; after the cell 5 is processed, the cell transport mechanism can transfer the cell 5 in the processing station to the unloading station by rotating the rotating arm 1, and the unloading device then transports the cell 5 in the unloading station to the collection area or the next process.
