If the bare cell is unqualified, the NG robot will clamp the unqualified bare cell to the NG unloading place for unloading, and the conveyor line will output an empty tray.

[0003] With the improvement of battery cell production efficiency, the detection efficiency of single bare battery cell can no longer match the existing battery cell production efficiency, affecting the subsequent processing efficiency. Summary of the invention

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, unless otherwise specified, "multiple" means 2 or more, and "several" means 1 or more. In addition, unless otherwise specified, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the description of the present invention, the description with reference to the terms "one embodiment", "some optional implementations" or "some optional embodiments" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0042] In order to improve the inspection and processing efficiency of bare cells, the existing inspection device adopts a tray to support two cells, and the inspection mechanism inspects the two cells at the same time. However, when a qualified cell and an unqualified cell are detected in a tray, if the existing unloading method is used, the NG robot clamps the unqualified bare cell to the NG unloading place for unloading and puts the qualified bare cell directly back into the tray. Then, there will be a situation where the tray output by the conveyor line supports only one qualified bare cell, which does not help to improve the efficiency of subsequent processing steps and still affects the subsequent processing efficiency.

[0043] The present invention can achieve the output of only fully loaded carrying trays and empty carrying trays, but not fully loaded carrying trays. Subsequent processing steps are all performed on the bare battery cells of the fully loaded carrying trays, which can improve the subsequent processing efficiency, while the empty carrying trays can be discarded, so it will not affect the processing efficiency, thereby effectively improving the production efficiency of the battery cells and reducing the production cost.

[0044] See also Figures 1 to 3One embodiment of the present invention provides a bare cell detection and unloading device, comprising:

[0045] Pallet conveying mechanism 10;

[0046] A plurality of carrying trays 20 are moved along the conveying direction of the tray conveying mechanism 10 under the conveyance of the tray conveying mechanism 10, and a plurality of carrying parts 21 for correspondingly carrying bare cells are arranged on the carrying trays 20;

[0047] The testing mechanism 30 has multiple testing stations, and is used to test bare cells on multiple testing stations at the same time;

[0048] OK pairing module 40, including a positioning component 41, a positioning power component 42 and a plurality of pairing platforms 43, the pairing platform 43 is preset with positioning areas, the number of the pairing platforms 43 and the number of the bearing parts 21 are the same, the positioning component 41 can be driven by the positioning power component 42 to move relative to the pairing platform 43 to drive the bare battery cells on the pairing platform 43 to move to the corresponding positioning areas;

[0049] The transport mechanism 50 is used to clamp the bare battery cell and move the bare battery cell between the inspection station, the pairing platform 43 and the carrying portion 21;

[0050] After the multiple bare cells on each carrying tray 20 are inspected by the inspection mechanism 30, three inspection situations will occur. The first inspection situation is: the number of qualified bare cells is equal to the number of carrying parts 21 of the carrying tray 20; the second inspection situation is: the number of qualified bare cells is less than the number of carrying parts 21 of the carrying tray 20 and is greater than 0; the third inspection situation is: the number of qualified bare cells is 0.

[0051] If the first detection situation occurs, that is, if the detection mechanism 30 detects that the number of qualified bare cells is equal to the number of carrying parts 21 of the carrying tray 20, the conveying mechanism 50 will place the qualified bare cells on the carrying parts 21 of the carrying tray 20, and the tray conveying mechanism 10 will convey the fully loaded carrying tray 20 away, and the fully loaded carrying tray 20 will be conveyed to the next production process for subsequent processing.

[0052] If the second detection situation occurs, if the number of qualified bare cells detected by the detection mechanism 30 is less than the number of the carrying parts 21 of the carrying tray 20 and is greater than 0, the handling mechanism 50 will place the qualified bare cells on the matching platform 43, and the tray conveying mechanism 10 will convey the empty carrying tray 20 away. The empty carrying tray 20 can be recycled before the tray conveying mechanism 10 is conveyed to the next production process. The empty carrying tray 20 can be recycled manually, or by using a sensor to detect whether there are cells on the carrying tray 20, and then using a cylinder to drive a push plate to push the empty carrying tray 20 out of the tray conveying mechanism 10, but this example is not limited.

[0053] When the second detection situation occurs multiple times, so that bare cells are placed in the positioning areas of all the pairing platforms 43, the transport mechanism 50 clamps the bare cells on all the pairing platforms 43 to the carrying part 21 of the carrying tray 20, and the tray conveying mechanism 10 transports the fully loaded carrying tray 20 away.

[0054] When the third detection situation occurs, there is no qualified bare battery cell, and the tray conveying mechanism 10 also conveys the empty carrying tray 20 away. The empty carrying tray 20 can be recycled before being conveyed to the next production process by the tray conveying mechanism 10.

[0055] In summary, the tray conveying mechanism 10 will only convey empty carrying trays 20 or fully loaded carrying trays 20 to the next production process, and will not convey carrying trays 20 with only a partial carrying portion 21 carrying bare batteries to the next production process. Therefore, subsequent production processes are all carried out on fully loaded carrying trays 20, which can effectively improve production and processing efficiency.

[0056] It should be noted that a fully loaded carrying tray 20 means that all the carrying parts 21 on the same carrying tray 20 carry bare cells, while an empty carrying tray 20 means that all the carrying parts 21 on the same carrying tray 20 do not carry bare cells.

[0057] In this embodiment, the bare cell detection and unloading device further includes a frame 60 , and the tray conveying mechanism 10 , the carrying tray 20 , the detection mechanism 30 and the OK pairing module 40 are all arranged on the frame 60 .

[0058] In this embodiment, the bare cell detection and unloading device also includes a controller, and the controller is signal-connected with the tray conveying mechanism 10, the detection mechanism 30 and the positioning power component 42, so as to facilitate the staff to operate each mechanism and component.

[0059] The specific structure of the pallet conveying mechanism 10 can be appropriately designed according to actual needs. For example, the pallet conveying mechanism 10 can adopt a mesh belt and chain conveying mechanism, a roller conveying mechanism, a chain plate conveying mechanism or a belt conveying mechanism, etc., but is not limited to this example.

[0060] In some optional embodiments, the number of the carrying parts 21 and the number of the matching platforms 43 are both 2. Of course, the number of the carrying parts 21 and the number of the matching platforms 43 can also be increased, and is not limited to 2.

[0061] The items that the detection mechanism 30 can detect on the bare cell can be selected according to actual needs. For example, the detection mechanism 30 can perform front and back appearance detection, bottom appearance detection, and tab detection on the bare cell, etc., and the detection items are not limited here. The structure and principle of the detection mechanism 30 are well known to those skilled in the art and will not be described in detail here.

[0062] In some optional embodiments, the number of detection stations, the carrying part 21 and the pairing platform 43 is the same. Of course, in other embodiments, the number of detection stations can be N times the carrying part 21, and N is greater than 1. The purpose of the number N being greater than 1 is that when the detection speed of the detection mechanism 30 is slow, multiple detection stations can be added so that the bare cells of multiple carrying trays 20 can be detected at the same time. For example, in one embodiment, the number of the carrying part 21 and the pairing platform 43 are both 2, N is 2, that is, the number of detection stations is 4, then after the bare cells of the two carrying trays 20 are placed in the detection station, one of the carrying trays 20 can leave first, and the other carrying tray 20 is on standby, in which the two bare cells are allowed to leave the standby carrying tray 20 or leave after being fully loaded with bare cells according to the detection situation after the detection is completed, and then the bare cells of the next carrying tray 20 are placed in the vacant detection station for detection, and the carrying tray 20 with the bare cells removed is on standby.

[0063] In some optional embodiments, the OK pairing module 40 also includes an alignment moving component 44, which is connected to the pairing platform 43 and is used to drive different pairing platforms 43 to move to the OK material picking station in sequence, and the conveying mechanism 50 is used to clamp the bare battery cells on the pairing platform 43 located at the OK material picking station to the bearing portion 21 of the carrying tray 20. The conveying mechanism 50 only needs to move to the OK material picking station each time, and the alignment moving component 44 moves the pairing platform 43 to the OK material picking station so that the conveying mechanism 50 can take away the bare battery cells, which is conducive to reducing the movement amount of the moving mechanism and reducing the demand for the freedom of movement of the moving mechanism. The specific structure of the alignment moving component 44 can select a suitable design according to actual needs. For example, the alignment moving component 44 can adopt a screw drive component, a rotary motor translation drive component, a belt translation drive component, a cylinder translation drive component or a linear motor translation drive component.

[0064] In some optional embodiments, the positioning assembly 41 includes a plurality of fixed positioning members 411, a plurality of first movable positioning members 412 and a plurality of second movable positioning members 413, wherein the two sides of the positioning area are respectively provided with a fixed positioning member 411 and a first movable positioning member 412, and the other two sides of the positioning area are respectively provided with a second movable positioning member 413 and a second movable positioning member 413, and the positioning power assembly 42 is drivingly connected to the first movable positioning member 412 and the second movable positioning member 413, and the first movable member and the second movable positioning member 413 are driven to approach or move away from the positioning area by the positioning power assembly 42. Each positioning area has a fixed positioning member 411, a first movable positioning member 412 and two second movable positioning members 413 for positioning, so that the four sides of the bare battery cell are accurately positioned with high positioning accuracy. Of course, the positioning assembly 41 can also adopt other suitable positioning structures, not limited to this example.

[0065] The bare cell can be positioned immediately after being placed on the pairing platform 43, or it can be positioned uniformly after all the pairing platforms 43 are placed with bare cells. In some optional embodiments, the positioning power assembly 42 includes a first translation drive assembly 421 and a plurality of second translation drive assemblies 422. The first translation drive assembly 421 is driven and connected to a plurality of first movable positioning members 412, and the second translation drive assembly 422 is correspondingly driven and connected to the second movable positioning member 413. The first translation drive assembly 421 can drive a plurality of first movable positioning members 412 to move synchronously, thereby simplifying the structure for positioning the bare cell. In this embodiment, after all the pairing platforms 43 are placed with bare cells, the first translation drive assembly 421 drives a plurality of first movable positioning members 412 to synchronously approach the positioning area to push the bare cell toward the fixed positioning member 411, and each second translation drive assembly 422 drives the second movable positioning member 413 to move, so that the second movable positioning members 413 on both sides of the same positioning area approach each other until the bare cell is clamped, so that the bare cell is stably and accurately positioned in the positioning area. The specific structure of the first translation drive assembly 421 and the second translation drive assembly 422 can be appropriately designed according to actual needs. For example, the first translation drive assembly 421 and the second translation drive assembly 422 can adopt a screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly or a linear motor translation drive assembly.

[0066] In some optional embodiments, the bare cell detection and unloading device also includes an NG unloading mechanism 60, and the transport mechanism 50 can move the bare cells between the detection station, the pairing platform 43, the load-bearing portion 21, and the NG unloading mechanism 60. When the second detection situation or the third detection situation occurs, that is, when the detection mechanism 30 detects unqualified bare cells, the transport mechanism 50 clamps the unqualified bare cells located at the detection station to the NG unloading mechanism 60, and the NG unloading mechanism 60 transports the unqualified bare cells away. Of course, in other embodiments, unqualified bare cells can also be unloaded and processed in other ways, not limited to this example.

[0067] See also Figure 4 In some optional embodiments, the NG unloading mechanism 60 includes an NG lifting component 61, a first NG transport component 62 and multiple second NG transport components 63. The NG lifting component 61 is driven and connected to the first NG transport component 62. The multiple second NG transport components 63 are arranged on one side of the first NG transport component 62 and are arranged in sequence from top to bottom. After the first NG transport component 62 is lifted and lowered to one side of any second NG transport component 63 under the drive of the NG lifting component 61, the transport end point of the first NG transport component 62 is connected to the transport starting point of the second NG transport component 63.

[0068] Since there are multiple unqualified conditions of the bare cells detected by the detection mechanism 30, each second NG transport component 63 can cache bare cells with different unqualified conditions, and the NG lifting component 61 transports the corresponding bare cells to one side of the corresponding second NG transport component 63 according to the unqualified conditions of the bare cells, and then the first NG transport component 62 transports the bare cells to the second NG transport component 63.

[0069] The transport destination of the first NG transport component 62 refers to the end position to which the first NG transport component 62 can transport the bare battery cell, and the transport starting point of the second NG transport component 63 refers to the starting position to which the second NG transport component 63 can transport the bare battery cell. The connection between the transport destination of the first NG transport component 62 and the transport starting point of the second NG transport component 63 does not necessarily mean that the first NG transport component 62 and the second NG transport component 63 are in physical contact, but only requires that the bare battery cell arriving at the transport destination of the first NG transport component 62 can be transported by the second NG transport component 63 from the transport starting point of the second NG transport component 63.

[0070] The specific structure of the NG lifting component 61 can be appropriately designed according to actual needs. For example, the NG lifting component 61 can adopt a screw lifting drive component, a rotary motor translation lifting drive component, a belt translation lifting drive component, a cylinder translation lifting drive component or a linear motor translation lifting drive component.

[0071] In some optional embodiments, a cache limit belt 631 is also provided on the second NG transport component 63, and the cache limit belt 631 can limit or release the bare battery cells located on the second NG transport component 63. A cache transport space is formed between the cache limit belt 631 and the transport starting point of the second NG transport component 63. After the bare battery cells are transported to the second NG transport component 63 by the first NG transport component 62, the second NG transport component 63 transports the bare battery cells until they are blocked by the cache limit belt 631, and then the next bare battery cell hits the bare battery cell blocked by the cache limit belt 631, so that multiple bare batteries are cached on the second NG transport component, which is convenient for observing the number of bare batteries on each second NG transport component 63, and then intuitively comparing the number of bare batteries in different unqualified situations.

[0072] In some optional embodiments, the tray conveyor mechanism 10 can transport the carrier tray 20 to the inspection loading station 11 and the standby station 12 in sequence, and the inspection loading station 11, the inspection mechanism 30, the standby station 12, the NG unloading mechanism 60 and the OK pairing module 40 are arranged in sequence along the conveying direction of the tray conveyor mechanism 10, so as to reasonably arrange the positions of each station and mechanism. The tray conveyor mechanism 10 transports the carrier tray 20 to the inspection loading station 11, the handling mechanism 50 moves the bare battery cells on the carrier tray 20 to the inspection station, and the tray conveyor mechanism 10 transports the carrier tray 20 to the standby station 12. According to the inspection situation of the inspection mechanism 30, the handling mechanism 50 moves the bare battery cells, and the tray conveyor mechanism 10 moves the empty carrier tray 20 or the fully loaded carrier tray 20 away from the standby station 12.

[0073] In this embodiment, the NG unloading mechanism 60 further includes an NG unloading conveying assembly 64, and the NG lifting assembly 61 can drive the first NG transport assembly 62 to rise and fall so that the transport starting point of the first NG transport assembly 62 is connected to the transport end point of the NG unloading conveying assembly 64, and the transport mechanism 50 places the unqualified bare cells on the NG unloading conveying assembly 64, and then the NG unloading conveying assembly 64 transports the bare cells to the first NG transport assembly 62. Of course, in other embodiments, the transport mechanism 50 can also directly place the unqualified bare cells on the first NG transport assembly 62.

[0074] In this embodiment, the bare cell detection and unloading device includes a plurality of tray conveying mechanisms 10, a plurality of detection mechanisms 30, a plurality of OK pairing modules 40 and a plurality of conveying mechanisms 50. The tray conveying mechanisms 10, the detection mechanisms 30, the OK pairing modules 40 and the conveying mechanisms 50 are arranged one by one, and the plurality of tray conveying mechanisms 10 are arranged side by side. Each tray conveying mechanism 10 can convey a carrying tray 20. The detection mechanism 30 corresponds to the bare cells of the carrying tray 20 on the tray conveying mechanism 10 for detection, the OK pairing module 40 corresponds to the bare cells of the carrying tray 20 on the pre-stored tray conveying mechanism 10, and the conveying mechanism 50 corresponds to the bare cells of the carrying tray 20 on the same tray conveying mechanism 10 for transfer. In addition, in order to simplify the structure, the NG unloading conveying assembly 64 extends through a plurality of tray conveying mechanisms 10, and the unqualified bare cells detected by each detection mechanism 30 are placed on the NG unloading conveying assembly 64, and are uniformly conveyed to the first NG transport assembly 62 by the NG unloading conveying assembly 64, so that only one NG unloading mechanism 60 needs to be arranged.

[0075] The transport mechanism 50 includes a multi-axis translation drive assembly and a plurality of clamping assemblies. The multi-axis translation drive assembly drives the clamping assembly to move in multiple directions, and the clamping assembly is used to clamp the bare battery cell. In this embodiment, the transport mechanism 50 includes a first clamping assembly, a second clamping assembly, and a third clamping assembly. The multi-axis translation drive assembly can drive the first clamping assembly to move between the detection station and the detection loading station 11, and the multi-axis translation drive assembly can drive the second clamping assembly to move between the detection station, the standby station 12, and the NG unloading conveying assembly 64. The multi-axis translation drive assembly can drive the third clamping assembly to move between the standby station 12, the NG unloading conveying assembly 64, and the positioning area. The specific structure of the multi-axis translation drive component can be appropriately designed according to actual needs. For example, in this embodiment, since the OK pairing module 40 has a positioning movement component 44, the multi-axis translation drive component can move in one less direction. The multi-axis translation drive component includes a first translation module and three second translation modules. The first translation module can drive each second translation module to move along the conveying direction of the pallet conveying mechanism 10, and the three second translation modules are correspondingly connected to the first clamping component, the second clamping component and the third clamping component to drive the first clamping component, the second clamping component and the third clamping component to rise and fall. The positioning movement component 44 drives the pairing platform 43 to move in a direction perpendicular to the conveying direction of the pallet conveying mechanism 10.

[0076] The specific structure of the first translation module and the three second translation modules can be appropriately designed according to actual needs. For example, the first translation module and the second translation module can adopt a screw translation module, a rotary motor translation module, a belt translation module, a cylinder translation module or a linear motor translation module.

[0077] The specific structures of the first NG transport component 62, the second NG transport component 63 and the NG unloading conveying component 64 can be appropriately designed according to actual needs. For example, the first NG transport component 62, the second NG transport component 63 and the NG unloading conveying component 64 can adopt mesh belt and chain transport components, roller transport components, chain plate transport components or belt transport components, etc., but are not limited to this example.

[0078] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
