Description

Technical Field

[0001] The utility model relates to a purge device and a purge system, in particular to a purge device and a purge system in a battery cell production process. Background Art

[0002] Solar photovoltaic cells, such as TOPCon cells, are produced on an assembly line using a cell loading telescopic platform to remove the cells (also known as silicon wafers) from a basket.

[0003] During this process, silicon wafer fragments may be generated. If the fragments are not removed in time, the device's sensors may be blocked by small fragments, making it impossible to determine whether the silicon wafers being transferred from the basket are intact. In this case, the device will misdetect and the machine will continue to descend. The silicon wafer fragments on the loading telescopic platform will block the silicon wafers coming out later, causing severe compression, which will trigger the alarm.

[0004] Currently, there's no automated way to clean incoming material debris from the telescopic loading platform. Instead, workers manually control the program to retract the platform and then manually remove the debris. This lack of automation requires manual intervention, which doesn't reduce manpower. Furthermore, workers frequently enter the machine, making it more susceptible to mechanical damage within the confined space. Furthermore, the machine's complex internal structure also poses a risk of damage to components.

[0005] Based on this, it is desired to provide a solution that can automatically clean silicon wafer fragments on the loading telescopic platform. Utility Model Content

[0006] One of the purposes of the present utility model is to provide a blowing device for battery cell loading, which can automatically blow away the debris on the loading telescopic platform, greatly saving the time of manual processing of debris, saving manpower and improving production efficiency.

[0007] In order to achieve the above-mentioned purpose, the present invention proposes a purging device for battery cell loading, which comprises:

[0008] An action element is provided above the battery cell loading telescopic platform, and the action element has a hollow cavity;

[0009] a driving element connected to the actuating element to drive the actuating element to actuate;

[0010] A brush connected to the tail end of the actuating element is driven by the actuating element to clean the surface of the telescopic platform for loading battery cells. The brush has an arm extending along the width of the telescopic platform, and the surface of the arm has a plurality of air outlet holes arranged along its length.

[0011] The pipe is arranged in the hollow cavity of the action element, one end of which is used to be connected to the air source, and the other end of which is communicated with the air outlet.

[0012] Furthermore, in the purging device for battery cell loading described in the present invention, the arm includes a first arm and a second arm extending toward two edges in the width direction of the battery cell loading telescopic platform.

[0013] Furthermore, in the purging device for battery cell loading described in the present invention, at least one group of air outlet holes includes a plurality of air outlet holes arranged in the circumferential direction of the arm.

[0014] Furthermore, in the purging device for battery cell loading described in the present invention, the action element includes a robotic arm.

[0015] Furthermore, the purging device for battery cell loading described in the present invention also includes a fixed gantry, which is arranged across the battery cell loading telescopic platform, and the action element is arranged on the gantry.

[0016] Furthermore, in the purging device for battery cell loading described in the present invention, the driving element includes a motor.

[0017] Furthermore, the purging device for battery cell loading described in the present invention also includes a control element, which is data-connected to the driving element.

[0018] Furthermore, in the purging device for battery cell loading described in the present invention, the control element includes a PLC.

[0019] Correspondingly, another object of the present invention is to provide a system including the above-mentioned purging device for battery cell loading, which can automatically sense whether there are debris on the telescopic platform for battery cell loading. When there are debris, the purging device will be automatically started to blow away the debris on the telescopic platform for loading, saving manpower.

[0020] In order to achieve the above-mentioned purpose, the present invention proposes a purging system for battery cell loading, which includes a battery cell loading telescopic platform and the above-mentioned purging device for battery cell loading.

[0021] Furthermore, in the purging system for battery cell loading described in the present invention, when the purging device includes a control element, the surface of the battery cell loading telescopic platform has a sensing element that is data-connected to the control element, which senses battery fragments dropped from the surface of the battery cell loading telescopic platform and their positions.

[0022] Furthermore, in the purge system for cell loading described in the present invention, the sensing element includes a photoelectric sensor.

[0023] Furthermore, in the purging system for cell loading described in the utility model, the surface of the cell loading telescopic platform has a hollow portion.

[0024] In this manner, in the present invention, when the sensing element detects debris on the surface of the retractable cell loading platform, it transmits the debris's location data to the control element. The retractable cell loading platform then moves toward the purge device used for cell loading. The control element simultaneously activates the actuator, which drives the brush to clean the located debris. Simultaneously, air is blown through the air outlet, sweeping debris of varying sizes off the platform through the hollowed-out portion of the retractable cell loading platform. When the sensor detects that the platform is clear of debris, the purge device stops, and the platform automatically returns to the wafer exit position of the basket, resuming wafer transfer.

[0025] The purge device and purge system for battery cell loading described in the present invention have the following advantages and beneficial effects:

[0026] The system can automatically sense whether there is debris on the telescopic platform for loading battery cells. When there is debris, the purge device will be automatically activated to blow away the debris on the telescopic platform, greatly saving the time of manual handling of debris, saving manpower and improving production efficiency.

[0027] This utility model effectively solves the problem that the current loading telescopic platform can only be retracted manually and then the debris can be removed manually, which is not possible to achieve automation. It also reduces the frequency of workers entering the machine, avoids mechanical injuries caused by workers operating in a confined space, and also avoids damage to components caused by people entering the machine.

[0028] The purge device and system for battery cell loading described in the utility model have simple structure, are easy to disassemble and maintain, and have low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a schematic diagram of the overall structure of a purge system for battery cell loading according to the present invention in one embodiment.

[0030] Figure 2 This is a schematic structural diagram of the brush of the blowing system for battery cell loading described in the present invention. DETAILED DESCRIPTION

[0031] The following will further explain and illustrate the purging device for battery cell loading described in the present invention in combination with the drawings and specific embodiments of the specification. However, such explanation and illustration do not constitute an undue limitation on the technical solution of the present invention.

[0032] Solar photovoltaic cells, such as TOPCon cells, are produced on an assembly line using a cell loading telescopic platform to remove the cells (also known as silicon wafers) from a basket.

[0033] During this process, silicon wafer fragments may be generated. If the fragments are not removed in time, the device's sensors may be blocked by small fragments, making it impossible to determine whether the silicon wafers being transferred from the basket are intact. In this case, the device will misdetect and the machine will continue to descend. The silicon wafer fragments on the loading telescopic platform will block the silicon wafers coming out later, causing severe compression, which will trigger the alarm.

[0034] Currently, there's no automated way to clean incoming material debris from the telescopic loading platform. Instead, workers manually control the program to retract the platform and then manually remove the debris. This lack of automation requires manual intervention, which doesn't reduce manpower. Furthermore, workers frequently enter the machine, making it more susceptible to mechanical damage within the confined space. Furthermore, the machine's complex internal structure also poses a risk of damage to components.

[0035] Based on this, the present invention provides a purge system for loading battery cells in one embodiment.

[0036] Figure 1 This is a schematic diagram of the overall structure of a purge system for battery cell loading according to the present invention in one embodiment.

[0037] like Figure 1 As shown, in this embodiment, the purging system may include: a purging device 100 for cell loading and a cell loading telescopic platform 200, wherein the cell loading telescopic platform 200 can be telescopically moved in its length direction.

[0038] Figure 2 This is a schematic structural diagram of the brush of the blowing system for battery cell loading described in the present invention.

[0039] like Figure 1 and Figure 2 As shown, in some specific embodiments, the purging device 100 for battery cell loading may include:

[0040] The action element 101 is located above the battery cell feeding telescopic platform. The action element 101 has a hollow cavity inside. The cavity is used to set the pipeline (due to Figure 1This is a schematic diagram of the external structure, so the pipeline inside the action element is not visible), one end of the pipeline is connected to the gas source providing the purge gas, and the other end is connected to the air outlet 105 on the brush 103.

[0041] The operating element 101 is connected to the driving element 102 so as to operate under the driving of the driving element 102 .

[0042] like Figure 2 As shown, the brush 103 is connected to the tail end of the operating element 101. The brush 103 has arms 1031 and / or 1032 extending along the width direction of the battery cell loading telescopic platform. The surface of the arms has a plurality of groups of air outlets 105 arranged along the length direction. In this way, the brush 103 can clean the surface of the battery cell loading telescopic platform under the drive of the operating element 101. For example, it can clean back and forth along the length direction of the loading telescopic platform 200. In addition, because the brush is provided with arms extending along the width direction of the battery cell loading telescopic platform, and the arms have air outlets arranged along the length direction of the arms, the brush can clean back and forth along the length direction of the loading telescopic platform 200 while also blowing air evenly in the width direction, thereby covering a larger cleaning range and better cleaning small debris.

[0043] In some more specific embodiments, Figure 2 As shown, the arms of the brush 103 may include a first arm 1031 and a second arm 1032 extending toward two sides of the width direction of the telescopic loading platform, thereby completely covering the width range of the telescopic loading platform 200. Of course, in other optional embodiments, it is also feasible to provide the first arm or the second arm only on one side.

[0044] In some more specific embodiments, at least one of the several groups of air outlet holes 105 provided on the arm may include several air outlet holes arranged in the circumferential direction of the arm, so as to achieve a better purging effect.

[0045] In some preferred embodiments, the actuator 101 may include a robotic arm. The robotic arm may swing at any angle, thereby driving the brush 103 to sweep away debris at any location. Since the robotic arm is a commonly used device in the art, the present invention does not improve the structure of the robotic arm and will not be further described here.

[0046] Accordingly, in some more specific embodiments, the drive element 102 may include a controlled electric motor.

[0047] Of course, in some other optional implementations, the action element 101 may also include a connecting rod type driving element composed of a connecting rod assembly and a joint element.

[0048] In addition, in some other optional embodiments, the actuating element 101 may also include a pneumatic cylinder or a hydraulic cylinder.

[0049] Continue reading Figure 1 In some more specific embodiments, the cell loading purge device 100 may further include a fixed gantry 104, which is arranged across the cell loading telescopic platform 200, with the actuating element 101 disposed on the gantry 104. Using the gantry 104 to position the actuating element 101 can reduce the floor space occupied by the device, decrease the spacing between devices, and increase space utilization. Of course, if sufficient space is available, a support can be provided on one side of the cell loading telescopic platform 200 to mount the actuating element 101, or other methods can be used to position the actuating element 101.

[0050] In some specific embodiments, the purging device 100 for loading battery cells may further include a control element (not shown in the figure), which is data-connected to the driving element 102 .

[0051] In some more specific embodiments, the control element may include a PLC.

[0052] Continue reading Figure 1 In some specific embodiments, a sensing element may be provided on the surface of the battery cell loading telescopic platform 200 , and the sensing element may sense the debris dropped from the surface of the battery cell loading telescopic platform 200 and its location.

[0053] In some more specific embodiments, the surface of the cell loading telescopic platform 200 is directly set as a sensing element, which can sense the debris falling on it. The sensing element is connected to the control element in the purge device 100 for cell loading.

[0054] In this manner, when the sensing element detects debris on the surface of the cell loading and retracting platform 200, it transmits a signal of the debris detection to a control element, such as a PLC. At this point, the cell loading and retracting platform 200 retracts in its longitudinal direction. Simultaneously, the control element, via the drive element 102, drives the actuating element 101, and thus the brush 103, downward. This action, combined with the longitudinal retraction of the cell loading and retracting platform 200, cleans the debris. Simultaneously, purge gas from the air outlet 105 also removes the debris.

[0055] Of course, in some embodiments, the robotic arm can also be controlled to drive the brush 103 to perform multi-angle cleaning, rather than just front and back cleaning.

[0056] When the sensing element senses that there are no more debris on the platform, the purging device 100 stops purging, and the cell loading telescopic platform 200 automatically returns to the cell outgoing position of the basket and continues to start transferring cells (i.e., silicon wafers).

[0057] In some more specific embodiments, the sensing element can be a photosensor.

[0058] In some more specific embodiments, Figure 1 As shown, the surface of the battery cell loading telescopic platform 200 has a hollow portion to facilitate the cleaning of debris falling from the battery cell loading telescopic platform 200.

[0059] This shows that the present invention effectively solves the problem that the current loading telescopic platform can only be retracted manually and then the debris can be removed manually, which is not possible to achieve automation. It also reduces the frequency of workers entering the machine, avoiding the possibility of mechanical injuries caused by workers operating in a confined space, and also avoids the possibility of damage to components caused by people entering the machine.

[0060] In addition, the purge system has a simple structure, is easy to disassemble and maintain, has low cost, and has wide adaptability.
