Description

Technical Field

[0001] The invention relates to the technical field of battery processing, and in particular to a current collecting plate loading device. Background Art

[0002] The cell is the most important component of the battery. The cell can only be assembled into a battery after it has been processed in sequence through mechanical / ultrasonic flattening, encapsulation, shelling, collector plate welding and sealing welding. Therefore, the performance of the cell has a direct impact on the performance of the battery, and the cell preparation process before battery assembly is very important.

[0003] In the prior art, when welding the collector plate, manual loading is usually used. First, the collector plates are picked up one by one; then, the selected collector plates are placed between the ends of the battery cells and the welding tooling; finally, the corresponding collector plates are spot welded one by one manually using a laser spot welding machine. This manual loading method is inefficient and has high labor costs, which seriously affects the welding efficiency of the collector plate, making it difficult to meet production needs.

[0004] At present, in order to improve the loading efficiency of the current collecting plate, the current collecting plate is first placed in the contoured groove of the positioning mechanism, and then the clamp on the flipping mechanism takes the material from the positioning mechanism. By flipping it 90 degrees, the current collecting plate is transformed from a horizontal placement state to a vertical placement state, and is placed between the end of the battery cell to be welded and the welding tooling, so that the welding of the current collecting plate can be conveniently realized.

[0005] However, the design of the above-mentioned current collecting plate feeding method is not reasonable. Since the current collecting plate is picked up and fed by a clamp, the requirements for the clamp are high, but the clamping of the current collecting plate is not reliable, and it is easy to cause the problem of clamping damage due to improper clamping operation. At the same time, in actual operation, only a single-station loading operation can be performed at a time, resulting in only a single-station current collecting plate welding. Since multiple laser spot welding machines can generally be arranged on a battery cell conveyor line, the existing feeding method cannot meet the welding requirements of the battery cells, and it is difficult to effectively improve the welding efficiency of the current collecting plate. Summary of the invention

[0006] The embodiment of the present invention provides a current collecting plate feeding device, which is used to solve the problem that the current collecting plate feeding method based on the clamp is unreliable, can only perform a single-station feeding operation at a time, and cannot meet the efficient welding requirements of the battery cell.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Figure 1 It is a schematic structural diagram of a collecting plate feeding device shown in this embodiment.

[0032] like Figure 1 As shown, the present embodiment provides a collecting plate loading device 1, comprising a loading robot 11, a loading positioning mechanism 12, a multi-station material dividing mechanism 13, a temporary material positioning mechanism 14 and a flipping mechanism 15 which are arranged in sequence, wherein the loading robot 11 is used to pick up materials from the collecting plate loading vehicle through a negative pressure adsorption component, and place the sucked collecting plate 2 in the contoured groove 121 on the loading positioning mechanism 12, the multi-station material dividing mechanism 13 includes a plurality of transfer units, and the plurality of transfer units can be used to move along a preset walking path, so as to transfer the collecting plate to different welding stations; the transfer unit has a negative pressure adsorption component for adsorbing the collecting plate; the temporary material positioning mechanism 14 is used to be arranged at the welding station, so as to connect the transfer unit and the flipping mechanism 15 one-to-one. Therefore, after the multi-station material distribution mechanism 13 shown in this embodiment distributes the current collecting plate 2 to the temporary material positioning mechanism 14 set at each welding station, the flipping mechanism 15 corresponding to the temporary material positioning mechanism 14 can flip the current collecting plate 2, so as to convert the current collecting plate 2 from a horizontal placement state to a vertical placement state, and at the welding station, the vertically placed current collecting plate 2 is placed between the end of the battery cell to be welded and the welding tooling, so that the current collecting plate 2 can be conveniently welded.

[0033] It should be noted here that, since each welding station is sequentially arranged along the cell feeding line, each transfer unit on the multi-station material distribution mechanism 13 shown in this embodiment is specifically used to move along the same straight walking path to meet the material feeding requirements of each welding station. Of course, the walking paths of each transfer unit shown in this embodiment include but are not limited to the same straight walking path, and can be specifically arranged accordingly according to the location of each welding station.

[0034] The feeding robot 11, the multi-station material dividing mechanism 13, the temporary material positioning mechanism 14 and the turning mechanism 15 shown in the present embodiment are all provided with negative pressure adsorption components. For the convenience of distinction, it is set that: the negative pressure adsorption component provided on the transfer unit of the multi-station material dividing mechanism 13 is the first negative pressure adsorption component 1302, the negative pressure adsorption component provided on the feeding robot 11 is the second negative pressure adsorption component 112, the negative pressure adsorption component provided on the temporary material positioning mechanism 14 is the third negative pressure adsorption component 143, and the negative pressure adsorption component provided on the turning mechanism 15 is the fourth negative pressure adsorption component 154.

[0035] Figure 2 This embodiment shows Figure 1 Schematic diagram of the structure of the loading robot 11.

[0036] like Figure 2 As shown, the loading robot 11 shown in this embodiment includes a multi-degree-of-freedom robotic arm 111 and a second negative pressure adsorption component 112. The head end of the multi-degree-of-freedom robotic arm 111 is installed on a fixed base 110, and the execution end of the multi-degree-of-freedom robotic arm 111 is installed with the second negative pressure adsorption component 112.

[0037] like Figure 3 As shown, the multi-degree-of-freedom robotic arm 111 shown in this embodiment includes a first arm section 1110 and a second arm section 1111, one end of the first arm section 1110 is installed on the fixed base 110 through a first rotation drive mechanism 1112, the other end of the first arm section 1110 is hinged to one end of the second arm section 1111 through a second rotation drive mechanism 1113, and the other end of the second arm section 1111 is installed with a vertically arranged single-rod cylinder 1114, the telescopic end of the single-rod cylinder 1114 is arranged downward, and a second negative pressure adsorption assembly 112 is installed, wherein the second negative pressure adsorption assembly 112 shown in this embodiment includes a fixed frame, and a plurality of pneumatic suction nozzles arranged in an array are installed on the fixed frame. Since the collecting plates are arranged in an array on the collecting plate loading cart, when the pneumatic suction nozzles on the second negative pressure adsorption assembly 112 shown in this embodiment are consistent with the arrangement of the collecting plates, multiple collecting plates can be adsorbed at one time by the second negative pressure adsorption assembly 112, and each collecting plate can be placed in the corresponding contoured groove of the loading positioning mechanism through the movement of the multi-degree-of-freedom robotic arm 111.

[0038] Figure 4As shown in this embodiment Figure 1 Schematic diagram of the structure of the middle loading positioning mechanism 12.

[0039] like Figure 4 As shown, the loading positioning mechanism 12 shown in this embodiment includes a first base 120, and a plurality of profiling grooves 121 are formed on the first base 120. The groove shape of the profiling groove 121 is adapted to the collecting plate and is used to place the collecting plate. Among them, the profiling grooves 121 shown in this embodiment are specifically arranged in four, and the four profiling grooves 121 are arranged at equal intervals along a straight line.

[0040] When the loading robot 11 loads materials into the corresponding contoured groove 121 of the loading positioning mechanism 12, in order to ensure the accuracy of the position of each collecting plate in the contoured groove 121, the loading positioning mechanism 12 shown in this embodiment is also configured with a first incoming material detection sensor 122 and a collecting plate positioning mechanism 123.

[0041] like Figure 4 As shown, the first incoming material detection sensor 122 shown in this embodiment is arranged opposite to the profiling groove 121, and the first incoming material detection sensor 122 can be a proximity switch or a photoelectric switch known in the art. The bottom of the profiling groove 121 shown in this embodiment is provided with a hollow through hole, and the first incoming material detection sensor 122 is installed on the lower side of the corresponding profiling groove 121, and the detection end of the first incoming material detection sensor 122 corresponds to the profiling groove 121.

[0042] At the same time, the collector plate positioning mechanism 123 shown in this embodiment has a positioning pressure head 1232 corresponding to the profiling groove 121. Specifically, the collector plate positioning mechanism 123 includes a telescopic rotary cylinder 1230, a deflection arm 1231 and a positioning pressure head 1232. The output end of the telescopic rotary cylinder 1230 is connected to one end of the deflection arm 1231, and the other end of the deflection arm 1231 is connected to the positioning pressure head 1232. Among them, the deflection arm 1231 shown in this embodiment is a "T"-shaped structure, so that two positioning pressure heads 1232 can be installed at the other end of the deflection arm 1231 at the same time, and the distance between the two positioning pressure heads 1232 is equal to the distance between the two profiling grooves 121.

[0043] In addition, the first incoming material detection sensor 122 shown in the present embodiment is communicatively connected to the collecting plate positioning mechanism 123. When the first incoming material detection sensor 122 detects that a collecting plate is placed in the profiling groove 121, the first incoming material detection sensor 122 can output a trigger signal, and the output end of the telescopic rotating cylinder 1230 instantly performs a yaw action according to the trigger signal to drive the yaw arm 1231 to deflect 90°, so that the positioning pressure head 1232 installed at the other end of the yaw arm 1231 is located exactly on the upper side of the profiling groove 121, and then, the output end of the telescopic rotating cylinder 1230 performs a retraction action to drive the yaw arm 1231 to descend a preset stroke, so that the positioning pressure head 1232 extends into the profiling groove 121, thereby realizing the correction and positioning of the posture of the collecting plate. After the calibration is completed, the output end of the telescopic rotating cylinder 1230 extends and swings in the opposite manner to the above, so that the positioning pressure head 1232 is away from the profiling groove 121, so that the first negative pressure adsorption component on the multi-station material distribution mechanism can absorb the collecting plate from the profiling groove 121 to perform multi-station partition feeding on the collecting plate.

[0044] Figure 5 As shown in this embodiment Figure 1 A schematic structural diagram of the multi-station material distribution mechanism 13.

[0045] like Figure 5 As shown, the multi-station material dispensing mechanism 13 shown in this embodiment includes two transfer units that can move along the same straight line walking path, and the two transfer units are respectively a first transfer unit 130 and a second transfer unit 131. The first transfer unit 130 and the second transfer unit 131 have the same structure, wherein the first transfer unit 130 includes a linear module 1300, a lifting and adjusting mechanism 1301 and a first negative pressure adsorption component 1302, the lifting and adjusting mechanism 1301 is installed on the slide of the linear module 1300, and the lifting and adjusting mechanism 1301 is connected to the first negative pressure adsorption component 1302. In this way, when the transfer unit absorbs the collecting plate from the loading positioning mechanism 12, the position of the transfer unit can be controlled first so that the first negative pressure adsorption component 1302 is located exactly on the upper side of the profiling groove 121, and then, the first negative pressure adsorption component 1302 is controlled to descend to a preset height through the lifting and adjusting mechanism 1301, so as to absorb the collecting plate from the profiling groove 121. Finally, when the collecting plate is absorbed, the lifting and adjusting mechanism 1301 controls the first negative pressure adsorption component 1302 to rise to a preset height, and the slide of the linear module 1300 can be moved to the pre-dividing station.

[0046] like Figure 5As shown, the lifting and adjusting mechanism 1301 shown in this embodiment includes a first vertical slide and a second vertical slide, the second vertical slide includes a plurality of slides, and is installed side by side on the first vertical slide in the horizontal direction, the first negative pressure adsorption component 1302 corresponds to the second vertical slide one by one, the first negative pressure adsorption component 1302 includes a cantilever and a pneumatic suction nozzle, one end of the cantilever is connected to the second vertical slide, and the other end of the cantilever is installed with the pneumatic suction nozzle. In this way, the height of each second vertical slide can be uniformly adjusted through the first vertical slide, and each second vertical slide can also fine-tune the height of the corresponding first negative pressure adsorption component 1302.

[0047] In one specific embodiment, two second vertical slides are installed side by side on the first vertical slide, each second vertical slide is connected to one end of a horizontally arranged cantilever, and two vertically arranged pneumatic suction nozzles are installed at the other end of the cantilever to achieve reliable adsorption of the collecting plate.

[0048] In a further preferred embodiment, the second transfer unit 131 shown in this embodiment is installed on the slide of the corresponding linear module of the first transfer unit 130. In this way, when the current collecting plate is divided and distributed, the second transfer unit 131 can move with the slide on the first transfer unit 130. When the first transfer unit 130 moves to the material distribution station, the slide of the corresponding linear module of the second transfer unit 131 can be started in time until the second transfer unit 131 also moves to the corresponding material distribution station. In this way, not only the material distribution efficiency is high, but also the current collecting plate can be distributed to two different material distribution stations at the same time.

[0049] Figure 6 As shown in this embodiment Figure 1 A schematic structural diagram of the temporary storage material positioning mechanism 14 from a first perspective; Figure 7 As shown in this embodiment Figure 1 A schematic structural diagram of the temporary storage material positioning mechanism 14 from a second viewing angle; Figure 8 As shown in this embodiment Figure 6 Schematic diagram of the local enlarged structure at K in the middle.

[0050] like Figure 6 and Figure 7 As shown, the temporary material positioning mechanism 14 shown in this embodiment includes a second base 140, on which a loading platform 141 and a positioning clamp 142 are provided. The positioning clamp 142 is horizontally installed on the upper side of the loading platform 141, and a contoured groove corresponding to the collecting plate is formed at the clamping end of the positioning clamp 142, and the clamping end of the positioning clamp 142 corresponds to the loading platform 141.

[0051] Therefore, when the multi-station material distribution mechanism 13 shown in the above embodiment places the collecting plate on the loading table 141 of the temporary material positioning mechanism 14 corresponding to the transfer unit, in order to prevent the collecting plate from being placed inaccurately and affecting the subsequent material picking operation of the flipping mechanism, this embodiment corrects the position of the collecting plate on the loading table 141 through the contoured slot on the positioning clamp 142.

[0052] like Figure 6 As shown, the positioning clamp 142 shown in this embodiment includes a first clamp 1420 and a second clamp 1421, and the clamping arm on the first clamp 1420 and the clamping arm on the second clamp 1421 correspond to form the clamping end shown in this embodiment, and the clamping arm on the first clamp 1420 is provided with a contoured slot, and the notch of the contoured slot faces the clamping arm on the second clamp 1421. It should be pointed out here that in order to simultaneously realize the positioning of the current collecting plates on the two loading platforms 141, the first clamp 1420 shown in this embodiment has two clamping arms, and correspondingly, the second clamp 1421 shown in this embodiment also has two clamping arms, so that two clamping ends can be formed on the positioning clamp 142 to simultaneously position the current collecting plates on the two loading platforms 141.

[0053] like Figure 8 As shown, a first through hole is formed on the stage 141 shown in this embodiment, and a third negative pressure adsorption component 143 is installed in the first through hole. The third negative pressure adsorption component 143 can be a pneumatic suction nozzle known in the art, and the pneumatic suction nozzle extends into the first through hole, and the suction end of the pneumatic suction nozzle faces the table surface of the stage 141. In this way, when the collecting tray is distributed on the stage 141, the third negative pressure adsorption component 143 can be started in this embodiment, and the collecting tray can be stabilized on the stage 141 based on the negative pressure adsorption force provided by the third negative pressure adsorption component 143.

[0054] Based on the improvement of the above embodiment, a second through hole is further formed on the stage 141 shown in this embodiment, and a second incoming material detection sensor 144 corresponding to the second through hole is provided on the temporary storage material positioning mechanism 14. The second incoming material detection sensor 144 can be a proximity switch or a photoelectric switch known in the art, and the second incoming material detection sensor 144 is respectively connected to the positioning clamp 142 and the third negative pressure adsorption component 143 for communication. In this way, when the current collecting plate is distributed to the stage 141, the second incoming material detection sensor 144 is immediately triggered, and while controlling the third negative pressure adsorption component 143 to start the negative pressure adsorption function, it can also control the positioning clamp 142 to move, so as to correct the position of the current collecting plate placed on the stage 141.

[0055] like Figure 7As shown, the positioning jaw 142 shown in this embodiment is also configured with a first driving cylinder 1422 and a second driving cylinder 1423. The first driving cylinder 1422 and the second driving cylinder 1423 are arranged back to back in the horizontal direction. The telescopic end of the first driving cylinder 1422 is connected to the first clamping body 1420, and the telescopic end of the second driving cylinder 1423 is connected to the second clamping body 1421. Therefore, by controlling the telescopic action of the first driving cylinder 1422 and the second driving cylinder 1423, the opening action and clamping action of the positioning jaw 142 can be controlled.

[0056] Fig. 9 As shown in this embodiment Figure 1 Schematic diagram of the structure of the turning mechanism 15.

[0057] like Fig. 9 As shown, the flipping mechanism 15 shown in this embodiment includes a third base 150, on which a flipping drive unit 151 is rotatably installed. The flipping drive unit 151 includes a reduction motor and a drive shaft. The output end of the reduction motor is connected to one end of the drive shaft through a coupling. A flipping table 152 is installed on the drive shaft, and a fourth negative pressure adsorption component 154 is installed at one end of the flipping table 152.

[0058] At the same time, the flip table 152 shown in this embodiment is equipped with a telescopic drive mechanism 153, the telescopic direction of the telescopic drive mechanism 153 is perpendicular to the axial direction of the flip drive unit 151, and the telescopic end of the telescopic drive mechanism 153 is connected to the fourth negative pressure adsorption component 154. The fourth negative pressure adsorption component 154 includes a fixed bracket and a plurality of pneumatic suction nozzles installed on the fixed bracket, wherein four pneumatic suction nozzles can be installed side by side on the fixed bracket, and every two pneumatic suction nozzles adsorb one collecting plate.

[0059] In the actual working process, when taking materials, the flip table 152 is arranged horizontally, and the adsorption end of the fourth negative pressure adsorption component 154 is in the same plane as the loading table 141 of the temporary material positioning mechanism 14. When the material is on the loading table 141 of the temporary material positioning mechanism 14 and the posture of the material is corrected, the flip driving unit 151 and the fourth negative pressure adsorption component 154 on the flipping mechanism 15 can be immediately started. While the fourth negative pressure adsorption component 154 adsorbs the current collecting plate, the flip driving unit 151 also drives the flip table 152 to flip 90°, so that the current collecting plate can be converted from a horizontal placement state to a vertical placement state, and at the welding station, the vertically placed current collecting plate is placed between the end of the battery cell to be welded and the welding tooling, so that the current collecting plate can be conveniently welded.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
