Description

Technical Field

[0001] The present invention relates to the technical field of battery production and processing, and in particular to a battery cell shunting and stacking system. Background Art

[0002] With the continuous development of society, lithium batteries are widely used in various electronic devices, new energy vehicles, and other industries. Due to their high energy density, safety, pollution-free, and environmentally friendly advantages, lithium batteries are increasingly popular, and demand for them is also increasing. The battery cell is the main component of a lithium battery. After processing, the battery cell requires shunting, information identification and recording, quality inspection, and grouping and stacking. Different specifications of battery cells are sorted and transported, and defective products are detected and separately output. Most existing production lines that implement this process are semi-automated, with relatively independent and dispersed equipment structures and low levels of automation integration. This requires larger workshops to accommodate various production lines, requiring significant infrastructure investment. Furthermore, the dispersed processes require manual transfer operations, which consumes a lot of labor and reduces production efficiency. Summary of the Invention

[0003] The main purpose of the present invention is to provide a battery cell shunting and stacking system to improve the integration and automation of the shunting, detection and stacking processes, replacing the existing production method that occupies a large area, requires manual operation for connection and transportation, is labor-intensive and has low efficiency.

[0004] In order to achieve the above object, the present invention adopts such technical solution:

[0005] A battery cell diversion and stacking system includes a feed module for conveying battery cells into the diversion and stacking system. The feed module uses a linear conveyor belt with the function of guiding and blocking workpieces. A sorting module is connected to the rear end of the feed module. The sorting module includes a sorting mechanism and a double-actuator discharging mechanism for screening and diverting workpieces. The sorting module has two output ends for outputting qualified workpieces and unqualified workpieces, respectively. The unqualified workpiece output end is connected to the unqualified discharging module. The qualified workpiece output end is connected to a positioning module. The positioning module is used to arrange and position multiple qualified workpieces.

[0006] The feeding module, positioning module and NG discharging module form a T-shaped feeding path with the sorting module as the intersection point;

[0007] A transfer robot is provided at the rear end of the positioning module, and a clamping module is connected to the end of the transfer robot. The clamping module includes a transfer clamping mechanism for clamping the workpiece and a bottom supporting mechanism for preventing the workpiece from falling off during the transfer process;

[0008] The outer side of the transfer robot is provided with a plurality of stacking modules and lifting and shifting modules. After being transferred by the transfer robot, the workpieces are stacked in the stacking modules and stacked with the help of the lifting and shifting modules.

[0009] Compared with the prior art, the present invention has at least the following advantages:

[0010] The present invention forms a T-shaped feeding path with the sorting module as the intersection point by combining the feeding module, the positioning module, and the NG discharging module, so that the feeding mechanisms in multiple processes are integrated in a highly tight joint form, and the workpieces that have been sorted, arranged, and positioned in the positioning module are transferred by the transfer robot, replacing the operation mode in which manual transfer of workpieces between different processes in the traditional structure is required. It greatly improves the degree of automation, improves production efficiency and the stability of process operation, and can also reduce the labor intensity of operators. Since the relationship between the stacking module and the lifting and shifting module and the transfer robot adopts an enclosed assembly relationship, the integration between the modules is further improved, the transfer efficiency and space utilization are improved, and the equipment footprint is reduced.

[0011] On the basis of the above technical solution, in order to improve the workpiece detection accuracy and sorting rate, the diversion stacking system includes at least two parallel and spaced positioning modules, each positioning module is connected to a sorting module at the front end, and a transition zone is provided between adjacent sorting modules for connection.

[0012] On the basis of the above technical solution, in order to ensure the continuity and timely connection accuracy of the workpiece transportation between the positioning module and the sorting module, a buffer transportation mechanism is provided between the positioning module and the sorting module.

[0013] On the basis of the above technical solution, in order to improve the efficiency of workpiece feeding and detection, the feeding module includes a feeding conveyor belt, on which are provided a plurality of feeding guides, forming a plurality of feeding paths for feeding and transmitting a plurality of workpieces. At the end of the feeding path, there is provided a feeding vision module for detecting the workpiece, and a feeding blocking member that can be controlled to open and close. The feeding blocking member is used to control the timing of the workpiece entering the sorting module.

[0014] On the basis of the above technical solution, the sorting module includes a front-to-back connected sorting mechanism and a double-motor discharging mechanism, and the sorting mechanism includes a feed end, a qualified workpiece output end and an NG workpiece output end; its feed end is connected to the output end of the feed module or the NG workpiece output end of another sorting module located at the front end, and the sorting mechanism has linear movement and rotation functions, and the output direction of the qualified workpiece is perpendicular to the direction of the feed end after its rotation.

[0015] The dual-motor discharging mechanism includes a feed end and a discharge end, wherein the feed end is connected to the qualified workpiece output end of the sorting mechanism, and the discharge end is connected to the feed end of the positioning module; the dual-motor discharging mechanism has at least two groups of feeding mechanisms with different numbers and directions of feeding paths, which are used to divert and output the workpieces at the feed end.

[0016] On the basis of the above technical solution, in order to ensure the clamping accuracy of the clamping mechanism and enable the workpiece to be converted into a state to be transferred according to a pre-set working mode, the positioning module includes a feeding mechanism connected to the qualified workpiece output end of the sorting module, and a positioning mechanism, and the positioning mechanism has a distance adjustment positioning structure parallel and / or perpendicular to the feeding direction of its feeding mechanism.

[0017] Based on the above technical solution, the positioning module also includes a lifting and positioning structure. This allows the workpiece to be adjusted and positioned three-dimensionally after being processed by the positioning module. After lifting, the top of the workpiece is exposed to a larger area, making it easier to operate the clamping module.

[0018] On the basis of the above technical solution, in order to further ensure the accuracy of clamping the workpiece, the transfer clamping mechanism is provided with a transfer clamping claw that can move longitudinally, and the transfer clamping claw is also connected to a lifting and positioning detection structure.

[0019] On the basis of the above technical solution, in order to ensure the safety of the workpiece during the transportation process of the clamping module and prevent the workpiece from falling and being damaged, the bottom support mechanism includes a flip frame that can be flipped along the horizontal axis. When the workpiece is clamped and transported by the transfer clamping mechanism, the flip frame can be flipped to the bottom of the workpiece to form a bottom support protection structure.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1, as Figure 1 As shown, this embodiment discloses a battery cell P diversion and stacking system, which includes a feeding module 100, a sorting module 200, an NG discharging module, a positioning module 400, a transfer robot 500, a clamping module 600, a stacking module 700 and a lifting and shifting module 800.

[0034] Among them, the feed is used to transport the battery cells P into the diversion stacking system, and to test the battery cells P to determine whether they are qualified. Figure 2 As shown, the feeding module 100 includes a feeding frame 11 that serves as a load-bearing support. A linear feeding conveyor belt 12 is provided on the top of the feeding frame 11. The feeding conveyor belt 12 is driven by a motor and can horizontally transport the battery cells P located on the top thereof.

[0035] A feed guide 13 is provided above the feed conveyor belt 12. The feed guide 13 consists of a horizontal rod and several guide wheels on the rod, forming four horizontal feeding paths with guiding effects. The feed guide 13 is connected and fixed to the feed rack 11 through a distance adjustment rack 131. The feed guide 13 is connected to the strip holes on the distance adjustment rack 131 through bolts. According to needs, the width of the feeding path can be adjusted to meet the conveying and guiding requirements of battery cells P of different specifications.

[0036] The end of the feed conveyor belt 12 is provided with a feed block 14 and a feed vision module 15. The feed vision module 15 is a prior art technology, and its structure and working principle will not be described in detail here. It is mainly used to take pictures of the battery cells P that have entered its target area, obtain image information, and then cooperate with the controller system to detect and determine whether the battery cells P are qualified, and record the product information of the battery cells P. It should be noted that the vision module is connected to the feed frame 11 via a universal adjustment bracket 151, which can flexibly adjust the shooting angle.

[0037] Combine Figure 3 The feed blocking member 14 includes a feed blocking fixing frame 141 fixedly connected to the feed frame 11, and a feed blocking cylinder 142 is installed on the side wall of the feed blocking fixing frame 141. The telescopic rod of the cylinder is vertically downward, and the bottom end of the telescopic rod is connected to a feed blocking lifting plate 143. The feed blocking lifting plate 143 horizontally spans the ends of the four feeding paths. Four blocks 144 are installed at the bottom of the feed blocking lifting plate 143, and each block 144 corresponds to a feeding path for blocking the battery cells P. To ensure stable lifting of the feed blocking lift plate 143, a feed blocking guide rail 145 and a feed blocking slider 146 are provided between the feed blocking lift plate 143 and the feed blocking fixed frame 141. The feed blocking guide rail 145 is a linear structure fixed to one side of the feed blocking fixed frame 141. The feed blocking slider 146 is fixed to the side of the feed blocking lift plate 143 near the feed blocking fixed frame 141 and is slidably engaged with the feed blocking guide rail 145. To improve lifting accuracy, the feed blocking fixed frame 141 is also provided with a feed blocking in-position sensor 147. Specifically, it comprises a U-shaped photoelectric sensor fixed to the feed blocking fixed frame 141 and a signal rod fixed to the feed blocking lift plate 143. The two cooperate to achieve the effect of in-position signal detection.

[0038] During actual use, the battery cell P enters from the feed end through an external grabbing and loading mechanism, is guided by the feed guide 13, and moves along the feeding path to the feed blocking member 14. After being blocked, the feed vision module 15 takes a photo of the battery cell P for inspection, and then the block 144 rises, and the battery cell P is output from the discharge end of the feed module 100.

[0039] like Figure 1 As shown, the sorting module 200 in this embodiment includes a sorting frame 21, on which a first sorting mechanism 200a, a second sorting mechanism 200b, a double-moving element discharging mechanism 200c, and a transition zone 200d are provided.

[0040] The first sorting mechanism 200a and the second sorting mechanism 200b have the same structure, are spaced apart from each other, and are connected by a transition zone 200d.

[0041] Specific, combined Figure 5 and Figure 6 The first sorting mechanism 200a includes a rotating material dividing base 21a installed on the sorting frame 21, and a rotating material dividing transverse movement seat 22a is provided on the rotating material dividing base 21a, which is independently connected to the drive motor, and its moving direction is consistent with the direction of the feed conveyor belt 12. Its main function is to move its top structure closer to or away from the output end of the feed module 100 to avoid subsequent rotational action interfering with the feed frame 11.

[0042] Atop the rotary distributing and transverse shifting seat 22a is a rotating seat 23a, independently connected to a drive motor, with its rotating shaft positioned vertically. Atop this seat 23a is a horizontal rotary distributing conveyor belt 24a, which connects to the output of the feed module 100. This belt has a guide structure and forms four feeding paths. At the end of each feeding path is a rotary distributing block 25a, which shares the same structure and principle as the feed block 14. With the help of the rotation of the rotating seat 23a, the rotating material distribution conveyor belt 24a can output the battery cells P in at least two directions, which is specifically reflected in: State 1, the rotating material distribution conveyor belt 24a is parallel to the rear end of the feeding module 100. When the NG battery cell P is detected, the rotating seat 23a remains stationary, and the rotating material distribution blocking member 25a is lifted, so that the NG battery cell P continues to move in the original direction and enters the second sorting mechanism 200b after passing through the transition belt 200d for sorting again. A visual inspection module can be set on the transition belt 200d to inspect the battery cell P again. In state 2, the rotating material distribution conveyor belt 24a is connected in parallel to the rear end of the feeding module 100. When the test result is a qualified battery cell P, the rotating material distribution transverse seat 22a first moves a certain distance to the rear end, and then the rotating seat 23a rotates 90°, so that the discharge end direction of the rotating material distribution conveyor belt 24a changes by 90° from the discharge direction of state 1. At this time, the qualified battery cell P can be transported to the double-acting sub-discharging mechanism 200c.

[0043] The dual-motor discharging mechanism 200c includes a dual-motor first base 21c and a dual-motor second base 22c fixed on the sorting frame 21, and a dual-motor first conveyor belt 23c and a dual-motor second conveyor belt 24c are respectively provided on the top of both. The two conveyor belts are horizontally and vertically directed. The top of the dual-motor first conveyor belt 23c is provided with 4 feeding paths connecting the output ends of the qualified battery cells P of the sorting mechanism, and each feeding path is provided with an independently controlled dual-motor first blocking member 25c, which can divert and output the 4 battery cells P here. A third dual-actuator conveyor belt 26c is provided on the second dual-actuator conveyor belt 24c, which moves transversely thereto. The direction of the third dual-actuator conveyor belt 26c is parallel to that of the first dual-actuator conveyor belt 23c, and both convey the battery cells P. However, the third dual-actuator conveyor belt 26c only has two feeding paths, each of which is terminated by a second dual-actuator blocking member 27c, which controls the flow of the battery cells P and coordinates feeding speed and timing. The output battery cells P pass through the buffer conveyor module and then enter the positioning module 400. The second dual-actuator conveyor belt 24c is used to control the relative position between the third dual-actuator conveyor belt 26c and the first dual-actuator conveyor belt 23c, as well as the output position of the battery cells P, ensuring that the battery cells P on the first dual-actuator conveyor belt 23c are staggered and transported backward in batches, achieving a diversion effect.

[0044] The buffer conveying module adopts a transmission structure of a multi-section differential conveyor belt, which can play a feeding buffer effect between the sorting module 200 and the positioning module 400.

[0045] like Figure 7 、 8 As shown, the positioning module 400 includes a positioning base 41, which is provided with a horizontal conveying roller 42. The conveying roller 42 is connected to a conveying motor 421 and a transmission member 422. The transmission member 422 specifically adopts a combination of a belt and a pulley structure, which can drive the conveying roller 42 to rotate and convey the qualified battery cells P output from the output end of the sorting module 200 to the end of the positioning module 400. A positioning stopper 43 is provided at the end for synchronously positioning multiple battery cells P located therein in the front and rear directions. The positioning stopper 43 is also connected to a positioning stopper cylinder 431 for adjusting the position of the positioning stopper 43 or pushing the battery cells P in the opposite direction of the conveying direction to improve positioning accuracy.

[0046] The positioning base 41 is also provided with multiple groups (10 groups in the figure) of positioning clamps 44, the bottom of which is connected to a positioning clamping cylinder 441. The positioning clamping cylinder 441 specifically adopts pneumatic fingers. The two work together to form a positioning clamping module 600, which clamps the battery cells P located on the top thereof respectively to complete the pre-positioning in the left and right directions.

[0047] The positioning base 41 is also provided with a positioning distance-changing mechanism 46 , which is a prior art and whose structure and working principle are not described in detail here. The positioning mechanism 46 is mainly used for synchronously adjusting the left and right spacing of multiple groups of battery cells P.

[0048] The bottom of the positioning clamping module 600 is connected to a positioning lifting mechanism 45, which specifically uses a cylinder as a lifting drive component, and is used to lift all the battery cells P clamped and fixed at the top of the rack, so that the top of the battery cell P extends above the rack, forming a state to be transported.

[0049] The transfer robot 500 in this embodiment is based on existing technology, and specifically has a six-axis rotation system, with a clamping module 600 connected to its free end.

[0050] like Figure 9 As shown, the clamping module 600 includes a transfer clamping base 61 connected to the transfer robot 500 , and a plurality of transfer clamping mechanisms 62 are provided on both sides of the transfer clamping base 61 , and a bottom supporting mechanism 63 is provided on the outer side of the transfer clamping mechanism 62 .

[0051] Further, such as Figure 10As shown, the transfer clamping mechanism 62 includes a clamping fixed frame 621 connected to the transfer clamping base 61, and the bottom of the clamping fixed frame 621 is provided with a clamping lifting guide rail 622 and a clamping lifting slider 623 that work in conjunction with each other. The clamping lifting guide rail 622 is fixed on the side wall of the clamping fixed frame 621, and the clamping lifting slider 623 can be longitudinally slid and clamped on the clamping lifting guide rail 622, and the bottom of the clamping lifting slider 623 is fixedly connected with a clamping lifting plate 629, which can follow the slider to rise and fall, and the bottom of the clamping lifting plate 629 is provided with a clamping opening and closing cylinder 626 and a transfer clamping claw 627, which work together to clamp the battery cell P located in the positioning module 400, and transport it to the stacking module 700 at the target position with the help of the transfer robot 500.

[0052] Further, such as Figure 11 As shown, the bottom supporting mechanism 63 includes a bottom supporting fixing frame 631, which is used to connect with the clamping and transporting base. The outer side of the bottom supporting fixing frame 631 is hinged with an inclined bottom supporting cylinder 632, and the end of the telescopic rod at the bottom of the bottom supporting cylinder 632 is hinged with a flipping frame 633. The flipping frame 633 is a horizontal U-shaped frame structure. The bottom supporting cylinder 632 can drive the flipping frame 633 to flip. Before flipping, the flipping frame 633 is located on the outer side of the transport clamping mechanism 62. When the transport clamping mechanism 62 clamps the battery cell P, in order to prevent the battery cell P from falling off during transportation, the flipping frame 633 will flip downward to the bottom of the battery cell P, and can be stuck on the bottom surface or the bottom corner of the battery cell P to form a protective bottom supporting structure for the battery cell P.

[0053] The stacking module 700 includes a stacking station on which a storage tray is placed. This tray is used to neatly store the battery cells P transferred by the transfer robot 500. The lifting and displacement module 800 includes a lifting and displacement mechanism for transporting, lifting, and shifting a tray filled with battery cells P, thereby achieving the effect of stacking multiple trays together. The stacking module 700 and the lifting and displacement module are prior art, and their structure and operating principles are not further described here.

[0054] In the actual arrangement of this embodiment, the rear end of the feeding module 100 is connected to the sorting module 200. The sorting module 200 includes a sorting mechanism and a double-acting sub-discharging mechanism 200c for screening and diverting the workpieces. The sorting module 200 has two output ends for outputting qualified workpieces and NG workpieces respectively. The NG workpiece output end is connected to a first NG discharging module 300a, and the qualified workpiece output end is connected to a positioning module 400. The positioning module 400 is used to arrange and position multiple qualified workpieces; the feeding module 100, the positioning module 400, and the NG discharging module constitute A T-shaped feeding path with the sorting module 200 as the intersection point; a transfer robot 500 is provided at the rear end of the positioning module 400, and a clamping module 600 is connected to the end of the transfer robot 500.

After being transferred by the transfer robot 500, the workpiece is stacked in the stacking module 700 and stacked with the help of the lifting and shifting module 800.

[0055] Example 2, based on Example 1, combined Figure 4 The feed blocking member 14 on the feed conveyor belt 12 can adopt a split structure to perform independent blocking control for each feeding path, which helps to further accurately control the transportation of the shunt battery cells P.

[0056] Example 3, based on Example 1, combined Figure 8 Each positioning and clamping module 600 is independently connected to a micro-adjustment device on its rear side. This device uses a micro-motor and a scissor-type linkage to independently control the left and right position of each positioning and clamping module 600, helping to further improve the accuracy of adjusting the spacing between the battery cells P. In other embodiments, the micro-adjustment device can also use other drive methods to achieve this effect.

The bottom of the clamping fixing frame 621 is provided with a clamping lifting position signal rod 625 at the corresponding position. The two work together to accurately detect and control the lifting and lowering of the transfer clamping claw 627, which helps to improve the clamping accuracy.

[0058] Furthermore, the transport clamping mechanism 62 is also provided with a transport vision module 65 for image recognition and detection of the clamped items. The transport clamping mechanism 62 is also provided with a suction cup mechanism 64, specifically a vacuum suction cup, for adsorbing the storage tray, for transporting the storage tray or ensuring that the storage tray and the battery cells P are transported more stably and reliably.

[0059] Furthermore, an abutment frame 628 is movably provided at the bottom of the clamping lifting plate 629, the top of the abutment frame 628 is connected to the clamping lifting slider 623, and the bottom of the abutment frame 628 is used to abut against the top of the battery cell P. When the transfer clamping claw 627 descends to the target position, the abutment frame 628 can lift the clamping lifting position signal rod 625 to the clamping lifting position sensor 624 to trigger the signal.
