Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery pieces, and particularly relates to a film removing mechanism for removing a PVD film layer of a carrier and a film removing device. BACKGROUND

[0002] In the production process of a solar heterojunction battery piece, a PVD (Physical Vapor Deposition) process is generally used to plate a film on the battery piece. Since the battery piece is placed in a carrier, the carrier is plated with a PVD film layer when the battery piece is plated with a film by the process. The thickness and width of the PVD film layer increase with the number of times of plating the battery piece with a film by the process. The PVD film layer formed compresses the placement space of the battery piece in the carrier, causing the battery piece to be inaccurately positioned and to fall during transmission. Therefore, the PVD film layer on the carrier needs to be peeled off in time.

[0003] However, the carrier is currently cleaned offline. After being cleaned, the carrier is used online again only after passing the inspection. This way of cleaning the carrier offline frequently reduces the production capacity of the production line to some extent, and the cost of cleaning and maintaining the carrier is high. Usually, the cleaning and maintenance of the carrier need to be completed with the help of manual work, which increases the working intensity of the workers and causes unnecessary waste of manual working hours.

[0016] The clamping member comprises a clamping plate arranged on the side edge of the positioning plate and a clamping cylinder used to drive the clamping plate to clamp and position the carrier.

[0017] As a further improvement of the present application, the laser emission module comprises an emission end used to emit the laser signal, and the positioning plate is provided with a first three-axis driving member used to drive the emission end to move above the carrier to strip the PVD film layer.

[0018] As a further improvement of the present application, the laser emission module further comprises a detection member used to detect the carrier before and after the PVD film layer is stripped.

[0019] The positioning plate is provided with a second three-axis driving member used to drive the detection member to move above the carrier for detection.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clearly understood, the embodiments of the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and not intended to limit the embodiments of the present application.

[0041] In the description of the embodiments of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly and specifically limited. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0042] In order to make the description of the present disclosure more detailed and complete, the following describes the embodiments of the embodiments of the present application; but this is not the only form of implementation or use of the specific embodiments of the present application. The embodiments include the features of the specific embodiments and the method steps and their order used to construct and operate these specific embodiments. However, other specific embodiments can also be used to achieve the same or equivalent functions and step sequences.

[0043] Please refer to Figures 1-7 The embodiments of the present application provide a film removal mechanism and a film removal device for removing a PVD film layer of a carrier, which can strip the PVD film layer on the carrier and effectively improve the production capacity of the production line. Please refer to Figure 1 The film removal mechanism for removing a PVD film layer of a carrier provided by the embodiments of the present application has a structure diagram, which specifically includes a transmission module 5, a jacking module 10, a positioning module 20, and a laser emission module 30.

[0044] As an optional embodiment, the transmission module 5 is used to transmit the carrier, so that the carrier moves along the transmission direction of the production line. The jacking module 10 includes a first blocking piece 11, a jacking piece, and a first transmission piece 14. The jacking module 10 is installed in the transmission direction of the transmission module 5. The first blocking piece 11 blocks the carrier 100 moving along the transmission direction. The jacking piece is used to jack the stationary carrier 100 in the height direction after being blocked. The first transmission piece 14 is used to transmit the jacked carrier 100, so that the carrier 100 is transmitted along the first direction and enters the positioning module 20.

[0045] Further, the positioning module 20 comprises a positioning plate 22 corresponding to the first conveying member 14, and a second blocking member 21 arranged on the positioning plate 22, the second blocking member 21 is used for blocking the carrier 100 conveyed to the positioning plate 22 by the first conveying member 14, and the laser emitting assembly is arranged above the positioning plate 22 and used for emitting laser to strip the PVD film layer 102 on the carrier 100.

[0046] It should be noted that in the production process of the existing solar heterojunction cell, the PVD production process is generally involved, and the cell is usually placed in the carrier 100, and the cell is plated with a film by the PVD process cavity. Since the cell is placed in the carrier 100, the carrier 100 will also be plated with a PVD film layer 102 while the cell is plated with a film by the process.

[0047] In actual operation, the average thickness of the cell plated with a film by a single process is about 100-110 nm, that is, the surface of the carrier 100 will inevitably be plated with a PVD film layer 102 with a thickness of about 100-110 nm by a single film plating process. Please refer to Figure 4 The structure diagram of the PVD film layer 102 in the film removal mechanism for removing the PVD film layer of the carrier provided by the embodiment of the present application can be observed. The periphery of the single carrier 101 is plated with a PVD film layer 102. The thickness and width of the PVD film layer 102 will increase with the number of cell process plating films. The PVD film layer 102 formed will compress the placement space of the cell in the carrier 100, causing the cell to be placed and positioned inaccurately, and to fall during the transmission process. Therefore, the PVD film layer 102 on the carrier 100 needs to be stripped in time.

[0048] Please refer to Figure 3 The structure diagram of the carrier 100 in the film removal mechanism for removing the PVD film layer of the carrier provided by the embodiment of the present application. The carrier 100 used in the transmission process usually comprises a plurality of arranged single carriers 101. Each single carrier 101 has a corresponding cell placed therein, so as to plate a plurality of cells at a time to improve the plating efficiency of the cell. Therefore, the carrier 100 mentioned in the subsequent film removal mechanism and film removal equipment for removing the PVD film layer of the carrier refers to the carrier 100 as shown in Figure 2 It should be noted that only one single carrier 101 is arranged for transmission and plating of the cell, which is also feasible, and those skilled in the art should know.

[0049] In the embodiment of the present application, the film removing mechanism for removing the PVD film layer of the carrier can be used for film removing treatment of the carrier 100 after the unloading is completed, that is, when the battery piece placed in the carrier 100 completes the unloading operation, the film removing mechanism for removing the PVD film layer of the carrier provided in the embodiment of the present application can be used for film removing treatment of the carrier 100, so as to avoid that after the carrier 100 and the battery piece are directly transmitted to the positioning module 20, the laser beam 311 emitted by the laser emission module 30 will cause damage to the battery piece. Therefore, the present application first performs the unloading operation on the carrier 100, and then moves the unloaded carrier 100 to the position corresponding to the jacking module 10.

[0050] Specifically, the carrier 100 which completes the unloading and moves along the transmission direction is blocked by the first blocking piece 11, so as to stop the movement of the carrier 100 and make the carrier 100 stationary on the jacking piece. The carrier 100 is jacked by the jacking piece, so that the current height of the carrier 100 is consistent with the height of the positioning plate 22 in the positioning module 20. Then, the carrier 100 is controlled by the first transmission piece 14 to move along the first direction, so as to move the carrier 100 to the positioning plate 22. In this way, the carrier 100 is moved to the position of the positioning module 20, and then the PVD film layer 102 plated on the carrier 100 is stripped by the laser emission module 30.

[0051] Further, the second blocking piece 21 is arranged on the positioning plate 22, and when the carrier 100 is transmitted to the positioning plate 22, the carrier 100 is blocked by the second blocking piece 21. Preferably, the second blocking piece 21 is arranged on the side of the positioning plate 22 away from the jacking piece, so as to avoid that the carrier 100 moves to other positions or moves out of the positioning plate 22 and falls.

[0052] In the embodiment of the present application, when the carrier 100 is transmitted to the positioning plate 22 by the transmission module and is blocked by the second blocking piece 21, the carrier 100 stops moving and is stationary on the positioning plate 22. At this time, the PVD film layer 102 on the carrier 100 is stripped by the laser emission module 30 arranged above the positioning plate 22. Since the carrier 100 has completed the transmission operation of the battery piece, after the stripping treatment of the PVD film layer 102 is completed, the carrier 100 can be continuously placed on the positioning plate 22 to wait for the worker to recycle, or the carrier 100 can be recycled to cooperate with the production line to plate the next round of battery pieces. The above treatment modes of the unloaded carrier 100 after the PVD film layer 102 is stripped are feasible, and the present application does not make further limitation on this.

[0053] As an optional implementation, please continue to refer to Figure 1The jacking member provided by the present application comprises jacking cylinders 12 and jacking plates 13 arranged at the ends of the jacking cylinders 12, and the number of the jacking cylinders 12 is preferably four, so as to support four corners of the jacking plates 13 and ensure the stability of the jacking plates 13 and the carrier 100 during jacking.

[0054] Further, the first blocking member 11 is arranged close to the jacking plates 13, when the carrier 100 is transported to the jacking plates 13 and close to the first blocking member 11, the carrier 100 is blocked by the first blocking member 11 and stops moving and is stationary on the jacking plates 13, and then the jacking plates 13 on which the carrier 100 is placed are jacked up to a height position corresponding to the positioning plate 22 by the jacking cylinders 12.

[0055] Optionally, the first transporting member 14 is arranged on the jacking plates 13, and the transporting direction of the first transporting member 14 is the first direction, so that the carrier 100 can be moved from the jacking plates 13 to the positioning plate 22 along the first direction by the first transporting member 14, so as to perform the corresponding PVD film layer 102 peeling operation on the positioning plate 22.

[0056] As an optional embodiment, it may be difficult to move the carrier 100 from the jacking plates 13 to the positioning plate 22 along the first direction only by the first transporting member, because the carrier 100 may not have enough power when being transported to the positioning plate 22, therefore, the second transporting member 23 is also arranged on the positioning plate 22 along the first direction, and the transporting direction of the second transporting member 23 is the first direction, so as to cooperate with the first transporting member 14 to transport the carrier 100 from the jacking plates 13 to the positioning plate 22, and of course, the carrier 100 after completing the PVD film layer 102 peeling operation can be transported to the original transporting direction by the first transporting member 14 and the second transporting member 23, so as to cooperate with the production line to recycle the carrier 100.

[0057] That is to say, by arranging the first transporting member 14 on the jacking plates 13 along the first direction and arranging the second transporting member 23 on the positioning plate 22 along the first direction, the carrier 100 can be transported from the jacking plates 13 to the positioning plate 22 along the first direction, and the carrier 100 after completing the PVD film layer 102 peeling operation can be transported from the positioning plate 22 to the jacking plates 13 along the first direction, so as to realize the movement of the carrier 100 between the jacking plates 13 and the positioning plate 22.

[0058] As an optional embodiment, the first blocking member 11 comprises a first blocking cylinder and a first blocking block connected to the end of the first blocking cylinder, which are arranged close to the lifting plate 13, preferably in the transmission path of the carrier 100 to block the carrier 100 being transmitted, and the first blocking block is driven by the first blocking cylinder to ascend or descend in the height direction, so as to block the carrier 100 transmitted to the lifting plate 13 and stop the movement of the carrier 100 being transmitted.

[0059] Similarly, in an optional embodiment, the second blocking member 21 comprises a second blocking cylinder arranged on the side of the positioning plate 22 away from the lifting plate 13, and a second blocking block connected to the end of the second blocking cylinder, which is driven by the second blocking cylinder to ascend or descend in the height direction, so as to block the carrier 100 transmitted to the positioning plate 22 and stop the movement of the carrier 100 being transmitted in the first direction, so as to cooperate with the laser emission module 30 to perform subsequent PVD film layer 102 peeling operation on the carrier 100.

[0060] Preferably, the number of the first blocking cylinder and the first blocking block can be set to at least two, and the number of the second blocking block and the second blocking cylinder can also be set to at least two, and of course, a third blocking member 25 can also be arranged at the side of the positioning plate 22, which also comprises a third blocking block and a third blocking cylinder, and can cooperate with the second blocking block and the second blocking cylinder to complete the blocking and positioning of the carrier 100. The above arrangement of the first blocking member 11, the second blocking member 21 and the third blocking member 25 is feasible, and the present application does not make further limitation.

[0061] Of course, a clamping member 24 for clamping the carrier 100 can also be arranged at the side of the positioning plate 22, so as to avoid the movement of the carrier 100 during the PVD film layer 102 peeling process, and affect the peeling precision and efficiency of the PVD film layer 102.

[0062] Specifically, the clamping member 24 comprises a clamping plate arranged at the side of the positioning plate 22, and a clamping cylinder for driving the clamping plate to clamp and position the carrier 100, which is driven by the clamping cylinder to move away from or close to the carrier 100, so as to clamp and fix the carrier 100.

[0063] It can be understood that the above-mentioned first blocking cylinder, second blocking cylinder and third blocking cylinder are used to drive the corresponding first blocking block, second blocking block and third blocking block to move in the height direction, so as to block the carrier 100 being transported, and the clamping cylinder is used to drive the clamping plate to move in the direction of approaching or moving away from the carrier 100, so as to clamp the carrier 100 which has been stationary, avoiding the position deviation of the carrier 100 in the subsequent process of laser stripping the PVD film layer 102.

[0064] In the embodiment of the application, the number of the clamping cylinder is preferably two, which can be arranged on one side of the positioning plate 22 corresponding to the third blocking piece 25, and of course other structures capable of clamping and fixing the carrier 100 are also feasible, which can be adaptively adjusted according to actual conditions.

[0065] As an optional implementation, the laser emission module 30 includes an emission end 31 for emitting a laser signal, and a detection piece 32 for detecting the carrier 100 before and after the PVD film layer 102 is stripped.

[0066] Please refer to Figure 2 The structure diagram of the emission end 31 in the film removing mechanism for removing the PVD film layer of the carrier provided in the embodiment of the application is shown. The emission end 31 in the laser emission module 30 is used to heat the PVD film layer 102 on the carrier 100 by high-temperature laser beam. The area a in the figure is before laser stripping, and the area b is after laser stripping. It can be observed that the laser beams 311 emitted by the emission end 31 can effectively strip the PVD film layer 102 on the carrier 100, and the way of stripping the PVD film layer 102 by the laser beams 311 is already relatively mature, which can realize high-precision, rapid point-to-point stripping, avoid damage to other positions of the carrier 100, reduce the cleaning time compared with the traditional way of cleaning the carrier 100, save the labor hours, and effectively improve the service life of the carrier 100.

[0067] Optionally, a first three-axis driving piece is arranged on the positioning plate 22, which is used to drive the emission end 31 to move above the carrier 100, move the emission end 31 to the position where the laser signal needs to be emitted, and adjust the focal length between the carrier 100 and the emission end 31 at the same time of emitting the laser signal, so as to ensure the optimal laser stripping effect.

[0068] In an alternative embodiment, the application also provides a detection member 32 for detecting the carrier 100 before and after the PVD film layer 102 is stripped, which can be specifically provided in the form of a distance measuring sensor, and the distance between the carrier 100 and the detection member 32 is detected to determine whether the PVD film layer 102 is stripped.

[0069] For example, the distance between a certain carrier 100 and the detection member 32 before stripping is X, and the distance between the carrier 100 and the detection member 32 after stripping is Y, and the difference between X and Y is the thickness of the PVD film layer 102 stripped by the laser beam 311, so that the difference before and after stripping can be used to determine whether the position is stripped.

[0070] Of course, it can be understood that the emission end 31 may have a certain deviation in actual stripping, and the PVD film layer 102 cannot be completely stripped, which may cause a certain amount of residual PVD film layer 102 on the carrier 100, so that the difference between X and Y before and after stripping can be ensured within a predetermined thickness range, and when the stripping thickness meets the predetermined thickness range, it is considered that the position of the carrier 100 has been stripped, and the application will not be described in detail here.

[0071] Since the PVD film layer 102 is usually plated around the single carrier 101, the application detects the four sides of each single carrier 101 by the detection member 32 before the laser beam 311 is emitted by the emission end 31, and then the PVD film layer 102 is stripped by the emission end 31, and then the detection member 32 is controlled to move above the carrier 100, and the detection member 32 is moved by the second three-axis driving member, and the four sides of each single carrier 101 after the PVD film layer 102 is stripped are detected again, and the difference before and after stripping is used to determine whether the carrier 100 has been stripped, and the effective stripping of each position of the carrier 100 that needs to be stripped is ensured.

[0072] It should be noted that the first three-axis driving member is used to drive the emission end 31 to move in the X-axis, Y-axis and Z-axis directions above the carrier 100, and the second three-axis driving member is also used to drive the detection member 32 to move in the X-axis, Y-axis and Z-axis directions above the carrier 100, and the first three-axis driving member and the second three-axis driving member can be realized by a common three-axis servo driver, or other driving motors and servo screws that can realize the movement of the emission end 31 and the detection member 32 in three directions, and the application does not limit the specific setting of the first three-axis driving member and the second three-axis driving member.

[0073] As an optional implementation, since the laser beam 311 peels off the PVD film layer 102, which belongs to the light-emitting and heat-emitting high-temperature etching phenomenon, a certain amount of smoke and dust particles may be generated during the peeling process. In order to avoid the accumulation and diffusion of these smoke and dust particles and cause pollution, the application also provides a dust prevention module for extracting and filtering the dust smoke.

[0074] Specifically, the dust prevention module includes a dust cover arranged above the positioning module and the laser emission module 30. The dust cover is preferably made of transparent material to facilitate monitoring of the film removal operation inside by relevant personnel. The dust prevention module is provided with a dust prevention host outside the dust cover. The dust prevention host and the dust cover are connected through a dust prevention pipe.

[0075] Optionally, the dust prevention module is provided with a dust prevention hole. The dust prevention pipe is arranged through the corresponding dust prevention hole. The dust prevention host is connected with the dust prevention pipe. The dust prevention host extracts and filters the dust smoke generated during the peeling process of the PVD film layer 102, avoids the diffusion of dust smoke to harm the health of workers, and is also provided with a waste pipe (not shown in the figure) connected with the dust prevention host. After the dust prevention host completes the extraction and filtration action, the filtered gas is discharged through the waste pipe.

[0076] As an optional implementation, the film removal mechanism for removing the PVD film layer of the carrier provided by the application also includes an information recognition module 50 arranged on the transmission path of the carrier 100. In actual application, each carrier 100 is usually provided with a corresponding number, and according to the past production experience, the PVD film layer 102 on a carrier 100 needs to be removed after 600-700 times of coating operation on the production line. Therefore, the application also provides a host controller for recording the coating times of each carrier 100.

[0077] Further, the application identifies the number of the carrier 100 through the information recognition module 50. The identification can be through the scanning code or through the FRID radio frequency identification. The application does not make further limitation on the specific setting mode of the information recognition module 50. As long as the number of the carrier 100 can be identified and the identified number can be transmitted to the host controller, it is feasible.

[0078] In an alternative embodiment, the monitoring of the carriers 100 is not only by the above-mentioned master controller recording the number of times of coating of each carrier 100, but also by the master controller recording the carriers 100 that are monitored to be abnormal and controlling the first blocking member 11 to block the carriers 100 that are monitored to be abnormal; the monitoring of the carriers 100 can also be by human observation of the thickness and width of the PVD film layer 102, or by human observation of whether the battery pieces are placed to be offset or whether there is an abnormal falling situation, so the application also provides an input module in communication connection with the master controller, when the staff observes that the carrier 100 has the above-mentioned abnormal phenomenon, the corresponding number of the carrier 100 is input through the input module, and then the master controller controls the first blocking member 11 to block the carrier 100 that needs to be stripped, and then performs the corresponding stripping operation.

[0079] Of course, other ways of judging whether the carrier 100 needs to be stripped are also feasible, and are not limited to the above-mentioned three cases, and those skilled in the art should know.

[0080] In the embodiment of the application, the information equipment module is arranged in the transmission path of the carrier 100 and close to the jacking module 10, so that the carrier 100 first reaches the position corresponding to the information identification module 50 for identification, and the corresponding number of the carrier 100 is transmitted to the master controller, at the same time the carrier 100 continues to be transmitted to the jacking plate 13 of the jacking module 10, when the master controller judges that the carrier 100 needs to be stripped or the master controller receives the number output through the input module, the master controller controls the first blocking member 11 to block the carrier 100 corresponding to the number that needs to be stripped, and does not block the carrier 100 that does not need to be stripped through the first blocking member 11, so that the carrier 100 continues to perform subsequent production work along the transmission direction.

[0081] That is, the master controller only controls the first blocking member 11 to block the carrier 100 that needs to be stripped, and does not block the carrier 100 that does not need to be stripped, and those skilled in the art should know.

[0082] As an alternative embodiment, when the carrier 100 completes the stripping operation in the positioning module 20, the master controller controls the second blocking member 21 and the clamping member 24 to stop clamping and positioning the carrier 100, and then the second transmission member 23 arranged on the positioning plate 22 is used to transmit the carrier 100 to the jacking plate 13, and then the jacking member drives the jacking plate 13 and the carrier 100 arranged on the jacking plate 13 to drop to the initial transmission height.

[0083] The transmission module 5 is arranged on both sides of the jacking plate 13 along the transmission direction of the carrier 100, and the carrier 100 is driven by the transmission module 5, so that the carrier 100 after the film removal continues to move along the transmission direction of the carrier 100 to perform other production actions of the production line.

[0084] In the embodiment of the present application, please refer to Figure 5 The function module diagram of the film removal mechanism for removing the PVD film layer of the carrier provided in the embodiment of the present application can set the above-mentioned main controller in the form of a common controller such as MCU (Microcontroller Unit), PFGA (Field Programmable Gate Array), PLC (Programmable Logic Controller), etc. The main controller is connected with the transmission module 5, the jacking module 10, the positioning module 20, the laser emission module 30, the dust removal module 40 and the information identification module 50 through wired or wireless mode. The specific wiring mode between each module and the main controller and how to control the working state of the devices in each module through the main controller are existing technologies widely used in the processor field, and the specific setting form of the above-mentioned main controller is not limited in the present application.

[0085] For example, the first transmission member 14, the second transmission member 23 and the transmission module 5 can be set in the form of a conveyor belt or a conveyor roller, and other setting modes selected for transmission of the carrier 100 are also feasible.

[0086] It can be understood that the transmission module 5 is arranged to transmit the carrier along the transmission direction of the production line, the first transmission member 14 is arranged on the jacking plate 13, the second transmission member 23 is arranged on the positioning plate 22, and the carrier moves in the first direction through the first transmission member 14 and the second transmission member 23 to cooperate with the laser emission module 30 to perform laser stripping on the PVD film layer attached to the carrier. Therefore, the transmission module 5, the first transmission member 14 and the second transmission member 24 can be set in the form of a conveyor belt or a conveyor roller, and the specific setting form is not limited in the present application.

[0087] Based on the film removal mechanism for removing the PVD film layer of the carrier, the present application further provides a film removal equipment, which comprises the above-mentioned film removal mechanism for removing the PVD film layer of the carrier, and a feeding module 1, a production module 2, a discharging module 3 and a return module 4 arranged along the transmission direction of the carrier 100.

[0088] Specifically, the jacking module 10 of the film removing mechanism for removing the PVD film layer of the carrier is arranged between the unloading module 3 and the returning module 4, and the positioning module 20 is arranged close to the jacking module 10 along the first direction.

[0089] Please refer to Figure 6 As can be seen from the structural diagram of the film removing equipment for removing the PVD film layer of the carrier provided in the related art, in the related art, the film removing equipment is only provided with the feeding module 1, the production module 2, the unloading module 3 and the returning module 4 along the transmission direction of the carrier 100.

[0090] The feeding module 1, the production module 2, the unloading module 3 and the returning module 4 are all provided with corresponding transmission modules 5, and the carrier is sequentially transmitted from the feeding module 1 to the returning module 4 and then from the returning module 4 to the feeding module 1 by the transmission modules 5 to perform the feeding action, which will not be described in detail herein.

[0091] In the prior art, when the PVD film layer 102 on the carrier 100 is removed, the carrier 100 can only be taken off line for cleaning, and after cleaning and inspection, the carrier 100 can be put on line for use again. This frequent off-line cleaning of the carrier 100 will reduce the production capacity of the production line to some extent, and the cleaning and maintenance cost of the carrier 100 is high, which usually needs to be completed by manual work, so that the working intensity of the workers is increased, and unnecessary labor time is wasted.

[0092] In the embodiment of the present application, please refer to Figure 7 As can be seen from the structural diagram of the film removing equipment for removing the PVD film layer of the carrier provided in the embodiment of the present application, the jacking module 10 is arranged between the unloading module 3 and the returning module 4. In actual production, the empty carrier 100 is transmitted to the feeding module 1 by the transmission module 5 to perform automatic feeding of the battery piece, and after feeding is completed, the carrier 100 is transmitted along the transmission direction to pass through the production module 2 to perform film plating operation, and after film plating is completed, the carrier 100 is transmitted along the transmission direction into the unloading module 3 to automatically unload the battery piece. It can be understood that the transmission of the carrier is completed by the transmission modules 5 arranged on the feeding module 1, the production module 2 and the unloading module 3.

[0093] Further, the empty carrier 100 after unloading continues to move along the transmission direction, and in the process of moving from the unloading module 3 to the jacking module 10, the carrier 100 first passes through the information recognition module 50 arranged close to the jacking module 10. The information recognition module 50 recognizes the number of the carrier 100 being transmitted, and the main controller judges whether the carrier 100 needs to be removed according to the number.

[0094] When the master controller determines that the current carrier 100 needs to be demasked according to the judgment basis provided in the above embodiment, the first blocking piece 11 is controlled to block the carrier 100 that needs to be demasked, and then the jacking piece lifts the stopped carrier 100 to a height position corresponding to the positioning plate 22, and then the first transmission piece 14 moves the carrier 100 to the positioning plate 22 in the first direction.

[0095] After the carrier 100 is moved to the positioning plate 22, the second blocking piece 21 and the clamping piece 24 are used to clamp and position the carrier 100, the detection piece 32 is driven to move above the carrier 100 to detect the carrier 100 that has not been demasked, and then the emission end 31 is driven to move above the carrier 100 to demask the position where the carrier 100 is covered with the PVD film layer 102, and then the detection piece 32 is driven to move above the carrier 100 to detect the carrier 100 after demasking. The detection piece 32 transmits the data detected before and after demasking to the master controller, and the master controller determines whether the carrier 100 is demasked according to the detected data.

[0096] In the demasking process, the dust removal host 42 is used to extract and filter the smoke and dust generated in the stripping process of the PVD film layer 102, so as to avoid the smoke and dust from directly diffusing into the air and causing harm to the workers. When the master controller determines that the demasking is completed, the second blocking piece 21 and the clamping piece 24 are controlled to release the clamping and positioning of the carrier 100, and then the second transmission piece 23 is used to move the carrier 100 from the positioning plate 22 to the jacking plate 13. The jacking plate 13 is provided with corresponding transmission modules 5 on the upper and lower sides, which make the carrier 100 after demasking continue to move in the transmission direction and enter the return module 4. The return module 4 is used to move the carrier 100 after demasking to the feeding module 1 for automatic feeding. In this way, the above steps are repeated, so that the battery piece production film is coated, and the carrier 100 that needs to be demasked is stripped by the laser beam 311. In this way, the production capacity of the production line is improved, and the service life of the carrier 100 is also improved, thereby effectively reducing the demasking cost.

[0097] For other details of the above technical solutions, please refer to the description of the demasking mechanism for removing the PVD film layer of the carrier provided in the above application embodiments, which will not be repeated here.

[0098] It can be understood that the technical features of the above embodiments can be combined in any way. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0099] The above embodiments are only exemplary embodiments adopted for illustrating the principles of the embodiments of the present application, and the embodiments of the present application are not limited thereto. Various modifications and improvements can be made by those of ordinary skill in the art without departing from the spirit and principle of the embodiments of the present application, and these modifications and improvements are also considered to be within the scope of protection of the embodiments of the present application.
