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. Under the condition that the production line is increased due to the need of increasing the production capacity of the battery pieces, the occupied area of the parallel production lines is increased.

Further, in a production system configured with a plurality of production lines, generally, one production line has one loading station and one unloading station. The loading station interfaces with an article vehicle, such as one being carried by an AGV vehicle. Similarly, the blanking station is also docked with the material cart being carried by the AGV cart. For each production line, if all need with the material trolley butt joint of AGV transport, can cause the whole grow of production line, and then lead to area grow.

In contrast, a production system for a battery having a plurality of production lines 100a for battery pieces (hereinafter, simply referred to as "production lines 100a" in some cases for convenience of description) is rearranged.

Referring to fig. 1 to 10, and mainly to fig. 1, the production system for battery pieces of the present embodiment includes: a plurality of production lines 100a, a plurality of first basket transfer units 300, and a plurality of second basket transfer units 200. Each production line 100a is used for processing a battery piece. The first basket turning unit 300 is provided at one end (front end in the drawing) of the production line 100a. The first basket transferring part 300 is used to transfer a basket (including a first basket 10a and a second basket 10b in the drawing) between the loading station 102a and the unloading station 103a of the production line 100a so that a cell sheet can be transferred between the production line 100a and the basket. A first basket of flowers is docked with a transfer section 300 to a production line 100a. The second basket transfer unit 200 is provided on the opposite side (front side) of the first basket transfer unit 300 from the production line 100a. The second basket transfer unit 200 is configured to transfer a basket to each first basket transfer unit 300 or transfer a basket from each first basket transfer unit 300 by extending over and abutting all of the first basket transfer units 300.

According to the production system for the battery piece of this embodiment, the floor space can be reduced. Specifically, in the present embodiment, all the production lines 100a share the second basket transfer unit 200, and the baskets are transferred to the respective production lines 100a via the second basket transfer unit 200, so that it is not necessary to provide a space for docking with an AGV vehicle or a space for docking with an upper stream line or a lower stream line at the loading station 102a or the unloading station 103a of each production line 100a, and the occupied area required for the entire production system can be greatly reduced. In addition, since the number of steps of the loading station 102a and the unloading station 103a is generally shorter than that of the other stations in each station of the production line 100a, even if a plurality of production lines 100a share one second basket transfer unit 200, the operation efficiency of the whole production line 100a is not affected.

In some embodiments, in order to further reduce the floor space required for the production system, a plurality of production lines 100a may be arranged side by side in the width direction thereof (left-right direction in the drawing). Each first basket of flowers 300 is butted against the production line 100a on the same side. For example, a plurality of production lines 100a may be arranged side by side in the left-right direction, and the number of the production lines 100a is determined according to the demand of capacity, and may have two, three or more, for example. This makes it possible to perform cell loading and unloading on all the front sides of the production line 100a, thereby further reducing the space required for the production system and optimizing the layout of the production system.

Referring to fig. 2 and 3 with the assistance of fig. 1, as an example, the production line 100a according to the present embodiment may be a production line 100a for laser doping a cell. The production line 100a may include: a processing station 104, an upper wire body 102 and a lower wire body 103. Wherein the battery pieces are processed at the processing station 104. The upper wire body 102 is disposed at one side of the processing station 104. The upper wire body 102 is used for carrying a battery piece to be processed. The lower wire body 103 and the upper wire body 102 are parallel. The lower wire body 103 is disposed at the other side of the processing station 104. The wire inserting body 103 is used for conveying the processed battery piece. The upper thread body 102 and the lower thread body 103 are butted against the first basket with the transfer part 300 on the same side. By arranging the lower wire body 103 and the upper wire body 102 in parallel on both sides of the processing station 104, the dimension in the width direction (left-right direction in the drawing) of the production line 100a can be reduced, thereby further reducing the floor space occupied by the production system. Specifically, since the production line 100a mainly includes only the upper line body 102, the lower line body 103, and the processing station 104 in the left-right direction, the layout of the stations of the production line 100a in the left-right direction can be optimized, and the size of the production line 100a in the left-right direction can be greatly reduced as compared with, for example, a carousel-type production line.

More specifically, the production line 100a may include: 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 are in one-to-one correspondence with 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 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 unit 400 transfers the battery pieces to be loaded from the basket in abutment with the upper wire body 102 (for convenience of description, the basket in abutment with the upper wire body 102 will be hereinafter sometimes referred to as "first basket 10 a") to the upper wire body 102, and transfers the battery pieces processed by the laser 106 from the lower wire body 103 to the basket in abutment with the lower wire body 103 (for convenience of description, the basket in abutment with the lower wire body 103 will be hereinafter sometimes referred to as "second basket 10 b").

By the production line 100a, the occupied area of the field can be reduced, and the productivity of the battery piece can be ensured. Specifically, by providing a plurality of processing stations 104 and a plurality of lasers 106 and arranging the lasers 106 so that the cells held in the corresponding processing stations 104 are processed in a staggered manner, that is, when one part of the lasers 106 are in a processing state, the other part of the lasers 106 are in a state to be processed and can load and unload the cells, the processing of the cells in one part of the processing stations 104 and the loading and unloading of the cells in the other part of the processing stations 104 can be simultaneously performed, so that the processing of the cells can be ensured not to affect the loading and unloading of the cells, and thus, the productivity of the cells can not be affected.

In addition, the "staggering" in this embodiment refers to the time staggering, that is, the laser 106 does not simultaneously process the battery 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 from the start of the processing of one laser 106.

The production line 100a is described in further detail below.

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. 2 and 3 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 disposed 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. 3 and with additional reference to FIG. 2, 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 of processing stations 104a" and "second group of processing stations 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 100a.

Referring to fig. 4, with additional reference to fig. 3, as described above, the material loading station 109 is docked with the upper wire 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 cell, for example. Therefore, the first docking manipulator 118 can transfer the battery piece from the rear end of the upper wire body 102 to the to-be-loaded station 109 according to the idle condition of each to-be-loaded station 109, so as to realize docking between the to-be-loaded station 109 and the upper wire body 102.

Referring to fig. 5 and 6, with supplementary reference to fig. 2 and 3, 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, and thus, in a state where the battery pieces are held at the station to be loaded 109, may be transferred to the processing station 104 in the left-right direction by the first line 110 and the second line 111.

With continued reference to fig. 6, 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. 6 and 3, 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. 3, likewise, the production line 100a may further include a plurality of stations to be blanked 121, the stations to be blanked 121 being respectively interfaced with the lower wire body 103, and one station to be blanked 121 being interfaced 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 3 and with additional reference to figure 4, 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. 7, with additional reference to fig. 2, in some embodiments, the second transfer portion 400 may include: an upper sheet transfer section 400a and a lower sheet transfer section 400b. The upper transfer unit 400a is disposed at the upper station 102a of the upper thread body 102. The upper plate transfer part 400a has a first slide assembly 404a, and the first slide assembly 404a can be driven to cantilever-extend from the upper wire body 102 and can extend into the slide area of the first 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 10 b.

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 may include a slide line, such as a belt line, that runs along the direction of travel of the on-line body 102.

The first basket transferring unit 300 includes two lifters (a first lifter 302a and a second lifter 302b described later) for driving the basket to ascend and descend. The first lifter 302a is butted with the upper thread body 102 and drives the first flower basket 10a to lift. The second lifter 302b is butted with the lower wire body 103 and drives the second basket 10b to lift. The lift range of the first lift 302a (and likewise the first lift 302 b) is set such that the slide region is above the first slide assembly 404a when the first basket 10a is driven lowermost and below the first slide assembly 404a when the first basket 10a is driven uppermost.

With the first slide assembly 404a inserted into the first basket 10a, the slide assembly line of the first slide assembly 404a is inserted into the first basket 10a, and the battery pieces falling from the first basket 10a into the slide assembly line are continuously and rapidly transferred to the online line 102 of the production line 100a as the first basket 10a descends. This can improve the transfer efficiency of the battery piece.

Referring to fig. 2, 7, and 8, 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 10 b.

The buffer unit 500 provided on one side of the upper thread unit 102 will be described. Specifically, cache portion 500 may include cache components 501. Wherein the buffer memory assembly 501 is lifted by a lifting robot (not numbered). The cache component 501 has: 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 503 has a plurality of first grooves 505 spaced apart from each other in the vertical direction. The second buffer member 504 is disposed on the other side in the width direction of the upper wire 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 supporting surface 101a of the upper thread body 102, and the second groove 506 located at the uppermost position among the plurality of first grooves 505 and the plurality of second grooves 506 is lower than the supporting surface 101a.

With reference to fig. 10 and with additional reference to fig. 1, the first basket transfer unit 300 will be described in detail below.

As described above, the first basket transferring part 300 is provided at one end of the manufacturing line 100a for transferring the battery pieces between the manufacturing line 100a and the baskets, and one first basket transferring part 300 is butted against one manufacturing line 100a. Further, the first baskets are butted against the production line 100a on the same side by the transfer unit 300.

Specifically, the first basket for flower 300 includes: the first transfer module 301 includes two elevators (hereinafter, the elevator to be docked with the upper wire body 102 may be referred to as a "first elevator 302a" and the elevator to be docked with the lower wire body 103 may be referred to as a "second elevator 302b" for convenience of description). The first transfer module 301 is linearly drivable in a direction (left-right direction in the drawing) in which the upper thread body 102 and the lower thread body 103 are juxtaposed, thereby transferring the basket (the first basket 10a when the basket is in a state of being butted against the upper thread body 102, and the second basket 10b when the basket is in a state of being butted against the lower thread body 103) between the upper thread body 102 and the lower thread body 103. The first lifter 302a is disposed at the right end of the driving direction of the first relay module 301, and the first lifter 302a may be butted against the first relay module 301 or the upper wire body 102. The first lifter 302a may drive the first basket 10a in the up-down direction so that the first basket 10a is docked with the loading station 102a or the first transfer module 301. The second lifter 302b is provided at the left end in the driving direction of the first relay module 301, and the second lifter 30b may be butted against the first relay module 301 or the down-wire body 103. The second lifter 302b may drive the second basket 10b in the up-down direction so that the second basket 10b is docked with the feeding station 103a or the first transfer module 301. Thus, the first basket transfer unit 300 can interface the basket with the production line 100a in which the loading station 102a and the unloading station 103a are arranged in parallel.

Specifically, the operation flow of the first basket transfer unit 300 is as follows:

after the first lifter 302a provided at one end of the first relay module 301 in the right direction is butted against the butting line 204 carried by the second basket transfer unit 200 via the relay line (not numbered) carried by the first relay module, and the first basket 10a is obtained, the first lifter 302a drives the first basket 10a to descend stepwise in the downward direction, so that the first basket 10a is butted against the loading station 102a. The first slide assembly 404a of the upper slide transfer part 400a of the upper wire body 102 of the production line 100a is driven to be cantilevered from the upper wire body 102 and can extend into the slide area of the first basket 10a, so as to transfer the battery plates in the first basket 10a to the loading station 102a of the upper wire body 102. Thereby completing the loading work of the battery piece.

When the first lifter 302a drives the first basket 10a to the position of docking with the first relay module 301, the first basket 10a held at the first lifter 302a is driven by the first relay module 301, and is linearly transferred from the right direction to the left direction, and is transferred to the second lifter 302b in the docked state with the first relay module 301.

Next, the second lifter 302b drives the second flower basket 10b to dock with the blanking station 103a of the down-line body 103. The second slide glass assembly 404b arranged at the lower glass transferring part 400b of the lower wire body 103 of the production line 100a transfers the battery glass at the blanking station 103a to the second basket 10b, thereby completing the blanking of the battery glass.

After the battery piece blanking operation is completed, the second lifter 302b is butted against the butting line 204 mounted on the second basket transfer unit 200 via a transfer line (not denoted by a reference numeral) mounted thereon, and the second basket 10b is transferred to the second basket transfer unit 200.

With continued reference to fig. 1, the second basket transfer unit 200 will be described in detail below.

The second basket transferring unit 200 includes a second transferring module 205, and the second transferring module 205 is linearly driven in a direction parallel to the production line 100a, spans all the lifts, and is respectively butted against the lifts. The docking line 204 is mounted on the second relay module 205 of the second basket relay unit 200. The docking line 204 is used to carry baskets of flowers. The stroke of the second transfer module 205 covers all the first basket transferring units 300, so that the docking line 204 can be docked with the elevator of each first basket transferring unit 300.

In order to simplify the layout of the second basket transfer unit 200 and improve the carrying efficiency of the second basket transfer unit 200, the second transfer module 205 may linearly drive the docking line 204. For example, the second transfer module 205 may be selected from a single-axis robot driven by a motor, and the docking line 204 may be mounted on the single-axis robot. As the docking pipeline 204, a belt line, a chain line, or the like may be selected. The docking line 204 is driven in a forward and reverse direction (forward and backward direction in the drawing) orthogonal to the driving direction of the single-axis robot of the second relay module 205.

With continued reference to fig. 1, the production system of the present embodiment may further include: covering all the loading sections 201 and the unloading sections 202 of the production line 100a, respectively. The loading section 201 is used for carrying baskets to be transferred to the respective production lines 100a. The blanking unit 202 is used for conveying baskets discharged from the respective production lines 100a. The feeding section 201 and the discharging section 202 are arranged side by side and are butted against the second basket middle rotating section 200. The form of the loading section 201 and the unloading section 202 is not particularly limited as long as the basket can be carried, and for example, a belt line, a chain line, or the like can be selected.

By providing the loading unit 201 and the unloading unit 202 that can cover all the production lines 100a, the operating rate of the loading unit 201 and the unloading unit 202 can be improved and the floor space occupied by the production lines 100a can be reduced when there are a plurality of production lines 100a. Specifically, in the present embodiment, all the production lines 100a share one loading section 201 and one unloading section 202, and baskets from the same loading section 201 are transported to different production lines 100a via the second basket transfer section 200, and baskets from different production lines 100a are transported to the same unloading section 202 via the second basket transfer section 200. Therefore, the operation rates of the feeding unit 201 and the discharging unit 202 can be greatly improved.

In addition, since the number of steps of loading and unloading the flower basket is relatively short in each station of the production line 100a compared with the number of steps in other stations, even if one loading section 201 and one unloading section 202 correspond to a plurality of production lines 100a at the same time, the operation efficiency of the whole production line 100a is not affected.

Although the production system has been described above as having the material loading unit 201 and the material unloading unit 202, the present invention is not limited to this. For example, the second basket relay 200 may be directly abutted against an AGV.

While examples of the present embodiments have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the embodiments, the scope of which is defined by the claims and their equivalents.
