Description

Production line for battery piece

Technical Field

The invention relates to the technical field of photovoltaic cells, in particular to a production line for cell pieces.

Background

In the prior art, there is a laser grooving process in the production process of solar cells (such as Topcon cells).

In the description of the present embodiment, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be broadly construed, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present embodiment in combination with the specific contents of the technical solutions.

Among the known techniques, there is a production line for a cell sheet such as a rotating disk type for laser doping a cell sheet. The various stations of the production line are arranged on a turntable. Specifically, for example, the turntable is provided with a loading station, a blanking station, a processing station and the like. The charging station and the discharging station are respectively butted with a flower basket for loading the battery pieces. However, since the stations of the production line for the carousel-type cell are arranged in a ring, the floor space of the production line becomes large. In the case of increasing the production line due to the need of increasing the production capacity of the battery pieces, the floor area of the parallel production lines is increased.

With reference to fig. 1 to 8, the cell production line 100a (hereinafter, simply referred to as "production line 100a" for convenience of description) is rearranged.

Referring to fig. 1 and 2, a production line 100a according to the present embodiment includes: a plurality of processing stations 104, a plurality of lasers 106, an upper wire body 102, a lower wire body 103, a first transfer section 107, and a second transfer section 400. The processing station 104 is used to hold the battery pieces. The plurality of lasers 106 correspond one-to-one to the plurality of processing stations 104, respectively. The plurality of lasers 106 are configured to alternately process the cell pieces held at their corresponding processing stations 104. The upper wire body 102 is disposed at one side (right side in the drawing) of the processing station 104. The upper wire body 102 is used for carrying battery pieces to be processed. The lower wire body 103 and the upper wire body 102 are parallel and disposed at the other side (left side in the drawing) of the processing station 104. The lower wire body 103 is used for conveying the battery piece processed by the laser 106. The first transfer portion 107 transfers the battery piece to be processed from the upper wire body 102 to the processing station 104, and transfers the battery piece processed by the laser 106 from the processing station 104 to the lower wire body 103. The second transfer part 400 transfers the battery pieces to be loaded from the first basket 10a butted with the upper wire body 102 to the upper wire body 102, and transfers the battery pieces processed by the laser 106 from the lower wire body 103 to the second basket 10b butted with the lower wire body 103.

According to the production line 100a of the present embodiment, the floor space can be reduced without affecting the productivity of the battery cells. Specifically, by providing a plurality of processing stations 104 and a plurality of lasers 106 and arranging the lower wire bodies 103 and the upper wire bodies 102 in parallel on both sides (both sides in the left-right direction in the drawing) of the processing stations 104, the dimension in the width direction (the left-right direction in the drawing) of the production line 100a can be reduced, and the floor space of the production line 100a can be reduced. In addition, since the lasers 106 are configured to process the battery pieces held in the processing stations 104 corresponding to the lasers 106 in a staggered manner, that is, when one part of the lasers 106 is in a processing state, the other part of the lasers 106 is in a state to be processed and can perform loading and unloading of the battery pieces, the processing of the battery pieces in one part of the processing stations 104 and the loading and unloading of the battery pieces in the other part of the processing stations 104 can be performed simultaneously, so that it can be ensured that the processing of the battery pieces does not affect the loading and unloading of the battery pieces, and thus, the productivity of the battery pieces is not affected.

In addition, the "staggering" described in the present embodiment refers to the time staggering, that is, the laser 106 does not simultaneously process the cell pieces held at the processing stations 104 corresponding to the laser. The staggered state includes a state in which the processing of one laser 106 is completed and the processing of the other laser 106 is started, and a state in which the processing of the other laser 106 is started after a period of time after the processing of one laser 106 is started.

The production line 100a of the present embodiment includes, for example, a substantially rectangular frame 108, and the length of the frame 108 in the front-rear direction is longer than the length in the left-right direction. The upper wire body 102 and the lower wire body 103 of the production line 100a are conveyed in the front-rear direction. The processing stations 104 are arranged along the running direction of the upper wire body 102, and the lasers 106 are respectively arranged above the processing stations 104 corresponding to the processing stations. Specifically, the processing stations 104 are arranged in a row in the conveying direction (front-rear direction) of the upper wire body 102 and the lower wire body 103, and are arranged in the middle of the rack 108 in the left-right direction. The processing stations 104 may include, for example, four (only two are included in fig. 1 and 2 for ease of illustration). The laser 106 is disposed above the processing station 104 by a mount (not shown) or the like, and processes the battery piece held in the processing station 104. A laser 106 is opposed to a processing station 104. The upper wire body 102 and the lower wire body 103 are symmetrically arranged on both sides of the processing station 104 in the left-right direction. Since the processing stations 104, the on-line bodies 102, and the off-line bodies 103 are mainly arranged in the left-right direction of the production line 100a, the width of the frame 108 in the left-right direction, and thus the width of the production line 100a, can be greatly reduced as compared with the conventional disk-type production line. When a plurality of production lines 100a need to be arranged, the occupied area required for the entire production line 100a can be greatly reduced.

With continuing reference to FIG. 2 and with additional reference to FIG. 1, in some embodiments, the manufacturing line 100a may also include a plurality of work stations 109 to be loaded. The to-be-loaded stations 109 are respectively butted with the on-line body 102, and one to-be-loaded station 109 is butted with one processing station 104. Specifically, for example, the processing stations 104 include four, and the stations to be loaded 109 also include four, and the stations to be loaded 109 are provided at the rear end of the upper thread body 102, for example, and are arranged at intervals in the front-rear direction of the frame 108. By arranging the station 109 for loading, the consistency of each process of the production line 100a can be improved by matching with the staggered processing mode of the laser 106.

For example, the four processing stations 104 are divided into two groups, each group having two processing stations 104 (for convenience of description, referred to as "first group processing station 104a" and "second group processing station 104b", respectively). Further, the four to-be-loaded stations 109 are also divided into two groups, each group having two to-be-loaded stations 109 (for convenience of description, referred to as "first group to-be-loaded stations 109a" and "second group to-be-loaded stations 109b", respectively). Wherein, the first group of processing stations 104a is butted with the first group of stations to be loaded 109a, and the second group of processing stations 104b is butted with the second group of stations to be loaded 109 b.

When the first group of processing stations 104a is in the processing state, the second group of processing stations 104b is in the idle state, and further, the first group of to-be-loaded stations 109a is in the idle state, and the second group of to-be-loaded stations 109b hold the battery pieces. In this case, the first group of stations to be loaded 109a is butted against the wire body 102 and receives the battery pieces from the wire body 102, and at the same time, the second group of processing stations 104b is butted against the second group of stations to be loaded 109b and receives the battery pieces from the second group of stations to be loaded 109 b. Therefore, the station to be loaded 109 is alternately butted with the processing station 104 or alternately butted with the upper wire body 102 according to the alternate processing state of the processing station 104. This can achieve consistency in the tact time of the production line 100a and ensure the productivity of the production line 100 a.

Referring to fig. 3, with additional reference to fig. 2, as described above, the material loading station 109 is docked with the wire loading body 102. In order to transfer the battery pieces from the upper wire body 102 to the station to be loaded 109, the first transfer part 107 may further include a first docking robot 118. The first docking robot 118 is disposed at one side of the upper wire body 102, and transfers the battery pieces held on the upper wire body 102 to the station to be loaded 109 (for example, to a first process line 110 described later). Thereby, the station to be loaded 109 can be docked with the upper wire body 102 by the first docking robot 118. Specifically, the first docking robot 118 may include, for example, a single-axis robot (not numbered) extending in the front-rear direction, and a driving stroke of the single-axis robot of the first docking robot 118 covers the rear end of the upper wire body 102 and all the stations to be loaded 109 in the front-rear direction. The first docking robot 118 has a bernoulli chuck 120 attached to its end for holding a battery piece. Therefore, the first docking manipulator 118 can transfer the battery piece from the rear end of the upper wire body 102 to the station 109 according to the idle condition of each station 109 to be loaded, so as to realize docking between the station 109 to be loaded and the upper wire body 102.

Referring to fig. 4 and 5, and with additional reference to fig. 1 and 2, in addition, in order to transfer the battery piece from the station to be loaded 109 to the processing station 104, the first transfer portion 107 may further include: a first pipeline 110 and a second pipeline 111 which are mutually butted. Wherein, the first assembly line 110 is configured at the material loading station 109. A second line 111 is disposed at the processing station 104 and interfaces with the first line 110. The first line 110 and the second line 111 may be belt lines running in the left-right direction, respectively, so that the battery pieces can be transferred to the processing station 104 in the left-right direction through the first line 110 and the second line 111 while being held at the station to be loaded 109.

With continued reference to fig. 5, the processing station 104 is also configured with a lifting fixture 112. The lifting jig 112 may include, for example, a vacuum suction plate 113 for holding the battery piece and a lifting cylinder 114 for driving the vacuum suction plate 113 to lift. In the initial state, the vacuum suction plate 113 is lower than the support surface of the second flow line 111 in the up-down direction. After the battery pieces are transferred to the processing station 104 through the first line 110 and the second line 111, the vacuum suction plate 113 is driven by the elevation cylinder 114 to be elevated above the support surface of the second line 111, whereby the battery pieces are held on the vacuum suction plate 113.

With continued reference to fig. 5 and 2, the production line 100a according to the present embodiment may further include a processing detection unit 115, and the processing detection unit 115 detects the position of the battery piece held at the processing station 104. The machining detection unit 115 may include: a detection light source 117 and a detection camera 116. The detection light source 117 is disposed at one side of the processing station 104, for example, is installed below the vacuum suction plate 113, and is used to supplement light to the edge area of the battery piece. The detection camera 116 is disposed on one side of the laser 106, for example, mounted on a mounting base for mounting the laser 106, and is used to detect the edge position of the cell. Thus, the specific position where the cell is held on the vacuum suction plate 113 can be detected by the processing detection portion 115, and the position of the laser 106 can be adjusted accordingly, thereby improving the accuracy of laser processing. In addition, because extra positioning and the like of the battery pieces are not needed, the carrying difficulty of the first production line 110 and the second production line 111 can be reduced, and the risk of the broken battery pieces and the like can be reduced.

With continued reference to fig. 2, likewise, the production line 100a may further include a plurality of stations 121 to be blanked, the stations 121 to be blanked are respectively butted with the lower wire body 103, and one station 121 to be blanked is butted with one processing station 104. The station 121 to be blanked may be set with reference to the station 109 to be loaded.

Likewise, in order to transfer the battery piece from the processing station 104 to the station 121 to be blanked, the first transfer part 107 may further include a third flow line 122. The third flow line 122 may be disposed at the station 121 to be blanked and interface with the second flow line 111. The third pipeline 122 may be set with reference to the first pipeline 110.

With continuing reference to figure 2 and with additional reference to figure 3, as well, the to-be-blanked station 121, in addition to interfacing with the machining station 104, interfaces with the lower wire body 103, as described above. The first transfer section 107 may further include a second docking robot 123. The second docking manipulator 123 is disposed at one side of the lower wire body 103 and transfers the battery pieces held at the to-be-blanked station 121 to the lower wire body 103. The second docking robot 123 may also be set with reference to the first docking robot 118. Therefore, the second docking manipulator 123 can transfer the battery piece from the station 121 to be blanked to the lower wire body 103, so as to realize docking between the station 121 to be blanked and the lower wire body 103. Thus, by providing the station 121 to be blanked and the second docking robot 123 for docking the station 121 to be blanked and the lower wire body 103, continuity of takt time of the production line 100a can be achieved, and productivity of the production line 100a can be ensured.

Referring to fig. 6, with additional reference to fig. 1, in some embodiments, the second transfer portion 400 may include: an upper sheet transfer section 400a and a lower sheet transfer section 400b. The loading transfer unit 400a is disposed at the loading station 102a of the loading line body 102. The upper piece transfer part 400a has a first piece-carrying component 404a, and the first piece-carrying component 404a can be driven to cantilever from the upper thread body 102 and can extend into the piece-carrying area of the first flower basket 10 a. The lower sheet transfer unit 400b is disposed at the lower sheet station 103a of the lower wire body 103. The lower plate transfer part 400b has a second slide assembly 404b, and the second slide assembly 404b can be driven to cantilever from the lower wire body 103 and can extend into the slide area of the second basket 10b.

The first and

second baskets

10a and 10b may be baskets known in the art. Since the upper sheet transfer unit 400a and the lower sheet transfer unit 400b have substantially the same configuration, the upper sheet transfer unit 400a will be mainly described here, and the lower sheet transfer unit 400b will be referred to as necessary.

By providing the upper sheet transfer unit 400a for performing the upper sheet and the lower sheet transfer unit 400b for performing the lower sheet, the continuity of the production line 100a can be improved, and the productivity of the production line 100a can be ensured.

Specifically, the loading transfer unit 400a is mounted on the loading station 102a of the loading line body 102. The first slide assembly 404a is cantilevered from the end of the upper wire body 102 and is extendable into the slide area of the first basket 10a, driven by, for example, a motor or an air cylinder. The first slide assembly 404a can include a slide line, such as a belt line, that runs in the direction of travel of the upper line body 102.

An elevator 402 is provided at an end of the upper wire body 102. The lifter 402 drives the first basket 10a to ascend and descend. The lift range of the elevator 402 is set such that the slide region is above the first slide assembly 404a when the first basket 10a is driven to the lowermost position and the slide region is below the first slide assembly 404a when the first basket 10a is driven to the uppermost position.

Under the condition that the first slide assembly 404a extends into the first flower basket 10a, the slide assembly line of the first slide assembly 404a extends into the first flower basket 10a together, and the battery pieces falling from the first flower basket 10a into the slide assembly line are continuously and quickly transferred into the online line body 102 of the production line 100a along with the descending of the first flower basket 10 a. This can improve the transfer efficiency of the battery piece.

Likewise, the end of the lower wire body 103 may be provided with a lifter 402. The second slide assembly 404b may also extend into the second basket 10b and transfer the battery piece of the offline body 103 to the second basket 10b.

Referring to fig. 1, 6, and 7, in some embodiments, the production line 100a may further include two cache portions 500. One of the buffer parts 500 is disposed at one side of the upper wire body 102 to buffer the battery pieces to be transferred from the upper wire body 102 to the processing station 104. Another buffer portion 500 is provided at the lower wire body 103 to buffer the battery pieces to be transferred from the lower wire body 103 to the second basket 10b.

The buffer unit 500 provided on one side of the upper thread unit 102 will be described. Specifically, the cache portion 500 may include a cache component 501. Wherein the buffer memory assembly 501 is lifted by a lifting robot (not numbered). The cache module 501 includes: a first cache piece 503 and a second cache piece 504. The first buffer member 503 is disposed on one side of the upper wire body 102 in the width direction (left-right direction in the drawing). The first buffer member 503 has a plurality of first slots 505 spaced apart in the vertical direction. The second buffer member 504 is provided on the other side in the width direction of the upper line body 102. The second buffer 504 has a plurality of second grooves 506 spaced apart in the vertical direction. The first groove 505 and the second groove 506 are opposed to each other in the width direction of the upper wire body 102, and can collectively receive the battery pieces held by the upper wire body 102. The driving stroke of the elevating robot of the buffer unit 500 in the vertical direction is set so that the first buffer member 503 and the second buffer member 504 are higher than the support surface 101a of the upper wire body 102, and the first groove 505 among the plurality of first groove portions 505 located at the uppermost position and the second groove 506 among the plurality of second groove portions 506 are lower than the support surface 101a.

By providing the buffer part 500, the continuity of the production in the production line 100a can be improved, and the collision of the battery pieces can be prevented.

Referring to fig. 1, 6, and 8, in some embodiments, the production line 100a may further include two deviation rectifying portions 511. One of the deviation rectifying portions 511 is disposed on one side of the upper wire body 102 and on one side of the upper piece transferring portion 400a facing the processing station 104. Another deviation rectifying part 511 is provided at one side of the lower wire body 103 and at one side of the lower sheet transfer part 400b facing the processing station.

Specifically, for example, one of the deviation rectifying portions 511 may be provided behind the upper sheet transfer portion 400a, for example. Another deviation rectifying portion 511 may be provided, for example, behind the lower sheet transfer portion 400b.

The deviation rectifying portion 511 provided on one side of the upper wire body 102 will be described. The deviation rectifying part 511 may include: a deskew drive assembly 512, a first limit assembly 513, and a second limit assembly 514. The first limiting device 513 and the second limiting device 514 are respectively disposed on two sides of the upper thread body 102 in the width direction, and are driven by the deviation rectifying driving device 512 to approach or separate from each other in the width direction of the upper thread body 102.

The deskew drive assembly 512 may include: a deviation rectifying motor 515 and a belt driving device 516. The belt drive 516 is driven to run by a skew correction motor 515. The belt drive device 516 has a drive wheel 517 connected to a deviation correcting motor 515 and a belt 518 driven by the drive wheel 517. The first restricting member 513 is connected to a portion (front side portion) of the transmission belt 518 on one side in the radial direction of the drive wheel 517, and the second restricting member 514 is connected to a portion (rear side portion) of the transmission belt 518 on the other side in the radial direction of the drive wheel 517. Thus, when the deviation correcting motor 515 is operated, the first and second restricting
