[0023] The structure and working principle of the battery shell insertion machine will be described below.

[0024] Please refer toFigure 2 As shown in Figure 2 , the present invention provides a battery casing inserting machine a1, which is mainly used for automatically inserting batteries into casings. Specifically, it automatically feeds the battery cells and the round tube casings, then inserts the battery cells into the round tube casings and discharges them, with high production efficiency and few defective phenomena. During the processing of the battery casing inserting machine of the present invention, the negative electrode of the battery cell faces upward during processing, and the negative electrode tab is in an upright state.

[0025] Specifically, the battery casing inserting machine a1 includes: a casing feeding mechanism a100, a casing gasket mechanism a200, a casing tab folding mechanism a300, a casing tab pressing mechanism a400, a casing round tube mechanism a500, a casing discharging mechanism a600, and a casing turntable processing mechanism a700. Of course, the battery casing inserting machine also includes a frame for installation, and the above-mentioned mechanisms are all installed on the frame. Among them, the casing feeding mechanism a100 is mainly used for feeding the battery cells, the casing gasket mechanism a200 is mainly used for cutting the wound insulating gaskets and attaching the cut insulating gaskets to the negative electrode end of the battery cells, the casing tab folding mechanism a300 is mainly used for folding the tabs of the battery cells, the casing tab pressing mechanism a400 is mainly used for flattening the folded tabs, the casing round tube mechanism a500 is mainly used for feeding the round tube casings, and at the same time, in cooperation with the casing turntable processing mechanism a700, it realizes inserting the battery cells into the casings. The casing round tube mechanism a500 is also used for transporting the batteries that have been inserted into the casings to the discharging area, that is, discharging them onto the battery rolling groove machine b1. The casing discharging mechanism a600 is mainly used for discharging the batteries that have been inserted into the casings from the discharging area, and the casing turntable processing mechanism a700 is mainly used for sequentially transporting the battery cells to the positions corresponding to the casing gasket mechanism a200, the casing tab folding mechanism a300, the casing tab pressing mechanism a400, and the casing round tube mechanism a500 for processing.

[0026] When the battery casing machine of the present invention is working, the casing feeding mechanism a100 feeds the battery cells and transports them to the casing turntable processing mechanism a700. Then, the casing turntable processing mechanism a700 transports the battery cells to the corresponding position of the casing gasket mechanism a200. The casing gasket mechanism a200 punches and cuts the insulating gasket and attaches it to the top of the battery cell. Then, the casing turntable processing mechanism a700 transports the battery cells to the corresponding position of the casing ear folding mechanism a300. The casing ear folding mechanism a300 bends the battery cell ears. Then, the casing turntable processing mechanism a700 transports the battery cells to the corresponding position of the casing ear pressing mechanism a400. The casing ear pressing mechanism a400 flattens the battery cell ears. Then, the casing turntable processing mechanism a700 transports the battery cells to the corresponding position of the casing round tube mechanism a500. The casing round tube mechanism a500 feeds the round tube casing and cooperates with the casing turntable processing mechanism a700 to assemble the completed battery cell into the round tube casing. Then, the casing round tube mechanism a500 transports the battery that has completed casing to the discharging area, and the casing discharging mechanism a600 discharges the battery to the specified position. Through the above process, the battery cells are successively subjected to the processes of feeding, attaching gaskets, folding ears, pressing ears, casing, and discharging, with high production efficiency, improved production quality. At the same time, the casing turntable processing mechanism transports the battery cells in the circumferential direction during the processing process, greatly reducing the equipment size, reducing the equipment occupation space, with a fast production beat and high production efficiency.

[0027] In one embodiment, please also refer to Figure 3 as shown. The casing feeding mechanism a100 includes a first feeding device a110, a feeding transport line a120, and a feeding turntable a130. Among them, the first feeding device a110 is used to grab the battery cells in the feeding area onto the feeding transport line a120. The feeding transport line a120 is used to transport the battery cells to the corresponding position of the feeding turntable a130. The feeding turntable a130 is used to feed the battery cells to the casing turntable processing mechanism a700. The automatic feeding of the battery cells is realized through the first feeding device a110, the feeding transport line a120, and the feeding turntable a130.

[0028] Among them, the first feeding device a110 includes a first feeding driving element a111, a second feeding driving element a112, and a first feeding clamp a113. The second feeding driving element a112 is connected to the first feeding driving element a111, and the first feeding clamp a113 is connected to the second feeding driving element a112. When the first feeding device a110 works, the first feeding driving element 11 drives the second feeding driving element a112 to move back and forth towards the feeding conveyor line a120, thereby driving the first feeding clamp a113 to move. The second feeding driving element a112 drives the first feeding clamp a113 to lift vertically. By driving the first feeding clamp a113 to move through the first feeding driving element a111 and the second feeding driving element a112, and cooperating with the first feeding clamp a113 to clamp the battery cell, automatic feeding of the battery cell is realized.

[0029] Specifically, the feeding turntable a130 includes a first rotating turntable a131 and a first turntable driving element a132. Among them, the first rotating turntable a131 is arranged between the feeding conveyor line a120 and the case-inserting turntable processing mechanism a700. A plurality of second feeding clamps a133 are distributed in a circular pattern on the first rotating turntable a131. When the feeding turntable a130 works, the first turntable driving element a132 drives the first rotating turntable a131 to rotate around its center, so that a plurality of second feeding clamps a133 on the first rotating turntable a131 rotate alternately between the feeding conveyor line a120 and the case-inserting turntable processing mechanism a700. Cooperating with the clamping of the battery cell by the second feeding clamp a133, the battery cell is transported from the feeding conveyor line a120 to the case-inserting turntable processing mechanism a700 for processing.

[0030] It should be noted that the case-inserting feeding mechanism a110 further includes a feeding distance separating device a140 arranged on the feeding conveyor line a120 and corresponding to the feeding turntable a130. Among them, the feeding distance separating device a140 is used to separate the battery cells on the feeding conveyor line a120, so that the distance between the battery cells to be fed matches the distance between the second feeding clamps a133 on the first rotating turntable a131.

[0031] Specifically, the feeding distance separating device a140 includes a distance separating screw a141 and a first distance separating driving element a142. Among them, the distance separating screw a141 is arranged along the transportation direction of the feeding conveyor line a120 and corresponds to the first rotating turntable a131 of the feeding. The first distance separating driving element a142 drives the distance separating screw a141 to rotate. When the battery cell is transported to the position of the feeding distance separating device a140 on the feeding conveyor line a120, driven by the rotation of the distance separating screw a141, the battery cells continue to move and are automatically separated from each other until the battery cells are transported to the position corresponding to the first rotating turntable a131, and the distance separating screw a141 stops rotating, waiting for the feeding turntable a130 to clamp and feed the battery cells.

[0032] In one embodiment, please refer to Figure 4 as shown. The gasket feeding mechanism a200 includes a gasket blanking device a210 and a gasket transporting device a220.

[0033] Specifically, the gasket blanking device a210 includes a loading wheel a211, a collecting wheel a212, a blanking track a213 arranged between the loading wheel a211 and the collecting wheel a212, and a blanking cutter (not shown in the figure) arranged below the blanking track a213. The wound insulating film sequentially passes through the loading wheel a211, the blanking track a213, and the collecting wheel a212. By driving the collecting wheel a212 to rotate through a driving element, automatic loading of the wound insulating film is realized under the drive of the wound insulating film. The blanking cutter punches out insulating gaskets with shapes matching the battery cells from the wound gaskets on the blanking track a213 from bottom to top.

[0034] Specifically, the gasket transporting device a220 includes a second rotating turntable a221 and a second turntable driving element a222.

The ear folding piece a330 and the ear folding rod a340 are located on the same straight line and intersect. The ear folding piece a330 is used to limit and guide the battery cell pole ear during bending to ensure the unified and stable bending effect of the pole ear. During operation, the first ear folding driving element a310 drives the ear folding piece a330 to move to one side of the battery cell pole ear, and the second ear folding driving element a320 drives the ear folding rod a340 to move from the other side of the pole ear towards the ear folding piece a330. Finally, the battery cell pole ear is bent through the cooperation of the ear folding piece a330 and the ear folding rod a340. The ear folding piece a330 has a bending inclined surface a331, and the bending point during the bending process of the battery cell pole ear is controlled through the bending inclined surface a331 to ensure the unified and stable bending effect of the battery cell pole ear.

[0036] Specifically, the in-shell ear folding mechanism a300 further includes an ear folding lifting driving element a350. The first ear folding driving element a310 and the second ear folding driving element a320 are arranged in parallel above the ear folding lifting driving element a350. The ear folding lifting driving element a350 simultaneously drives the first ear folding driving element a310 and the second ear folding driving element a320 to perform lifting motion. When the in-shell ear folding mechanism a300 finishes bending the pole ear of a battery cell, the ear folding lifting driving element a350 simultaneously drives the first ear folding driving element a310 and the second ear folding driving element a320 to rise to avoid affecting the transmission process of the battery cell by the in-shell turntable processing mechanism a700. When the battery cell whose pole ear needs to be bent is transported to the position corresponding to the in-shell ear folding mechanism a300, the ear folding lifting driving element a350 simultaneously drives the first ear folding driving element a310 and the second ear folding driving element a320 to descend, and then the in-shell ear folding mechanism a300 bends the battery cell pole ear.

[0037] In an embodiment, please continue to refer to Figure 5 As shown in the figure, the in-shell pole ear pressing mechanism a400 includes a pressing ear driving element a410 and a pressing ear rod a420.

During operation, the battery cell with the pole ear bent is transported to the lower part of the in-shell pole ear pressing mechanism a400 under the transportation action of the in-shell turntable processing mechanism. At this time, the pressing ear driving element a410 drives the pressing ear rod a420 to descend towards the in-shell turntable processing mechanism a400, and then the pressing ear rod a420 is used to flatten the battery cell pole ear. In order to reduce the damage to the pole ear during the pressing ear process, the bottom of the pressing ear rod a420 is made of soft material, such as silica gel, so as to reduce the damage to the pole ear during the pressing ear process and ensure the production quality.

After welding, a gasket is placed to complete the battery operation before grooving. Then, the battery case is grooved to clamp the battery core and prevent the battery core from detaching from the battery case, facilitating subsequent operations.

It should be noted that the pressure sensors arranged in the grooving device b910 and the welding device b400 of the present invention are used to ensure the uniformity of the battery welding quality and the grooving quality. Specifically, since the battery will always have a certain deviation due to external factors during movement and transfer, such as deviation caused by the gap of the battery slot or wear after long-term use of the equipment, when the battery core is welded or the battery case is grooved, through the action of the pressure sensor, the solder injection amount and welding force of the welding torch and the rolling pressure of the hob b911 of the grooving device can be determined according to the pressure received by the welding torch and the hob b911 of the grooving device. Thus, welding or grooving can be performed according to the real-time pressure of the welding torch or the tool, rather than by a preset fixed value, so as to improve the uniformity of the battery welding and grooving processes and effectively improve the welding and grooving quality.

[0068] Please refer to Figure 22, specifically, the point-cover battery feeding mechanism c200 includes a chuck c210, a chuck control device c220, and a battery transfer storage tank c230. The chuck control device c220 can be a combination of a cylinder and a motor. The motor drives the contraction of the chuck c210, and the cylinder controls the lifting and movement of the chuck c310. The battery transfer storage tank c230 is located between the point-cover conveyor belt c100 and the point-cover incoming material storage belt c10, and the point-cover incoming material storage belt c10 is the incoming material storage point of the previous process. There are multiple chucks c210 arranged in two columns. One column of chucks c210 picks up the batteries on the point-cover incoming material storage belt c10 and places them on the battery transfer storage tank c230, and the other column of chucks c210 picks up the batteries on the battery transfer storage tank c230 and places them on the point-cover conveyor belt c100. The above method can effectively shorten the moving distance of the battery, thereby effectively improving the conveying efficiency of the battery. In addition, at the starting position of the point-cover conveyor belt c100, there is also a vacancy sensing device c120 for detecting whether there is a battery in the point-cover battery slot c110, so as to avoid the phenomenon that the chuck c210 fails to pick up the battery, thereby ensuring that each point-cover battery slot c110 has a battery, improving the utilization rate of the point-cover battery slot c110, and thus improving the production efficiency of the battery.

[0069] Please refer to Figure 24 , the point-cover ear adjustment mechanism c400 includes a sensor c410, a runner c420, and a runner control system c430. The sensor c410 is located above the point-cover conveyor belt c100, and the runner c420 is located on one side of the point-cover conveyor belt c100. The runner c420 control system is used to drive the runner c420 to adjust the position of the ear. The sensor c410 can use a fiber optic sensor, which can be used to detect the position information of the ear and transmit the position information of the ear to the runner control system c430. Then, the runner control system c430 controls the movement and rotation of the runner c420 to make the runner c420 contact the battery, and uses the friction between the two to drive the rotation of the battery, so as to achieve the purpose of adjusting the direction of the battery ear. The runner control system c430 can use a combination of a motor and a cylinder to control the rotation and movement of the runner c420.

[0070] Please refer to Figure 26, the tab bending mechanism c600 includes a gripper c610 and a gripper control system c620.

The motor controls the opening and closing of the gripper c610. That is, during operation, the two bent arms are used to clamp the battery tab. Since the contact surface c601 of the two bent arms is inclined, the tab will be bent when they come into contact. On the one hand, the bent tab does not affect the subsequent welding of the battery tab and the battery cover. On the other hand, it can also prevent the battery cover from hitting the electrode plate during alignment, resulting in lateral displacement or damage of the electrode plate.

[0071] Please refer to Figure 27 , Figure 31 and Figure 32 , the cover feeding device c800 includes a vibrating bowl c810, a rotary fixture c820, a fixture control system c930, and an adsorption turntable c840.

The fixture control system c930 is used to control the lifting and rotation of the rotary fixture c820. Among them, the vibrating bowl c810 is an existing conventional technology, and its working principle is as follows: A pulse electromagnet is provided under the hopper, which can make the hopper vibrate in the vertical direction. Due to the inclination of the spring c930 plate, the hopper makes a torsional vibration around its vertical axis. The parts in the hopper move along the spiral track until they reach the discharge port due to this vibration. The rotary fixture c820 picks up the battery cover horizontally placed at the discharge port of the vibrating bowl c810, places it on the adsorption turntable c840, and makes it in a vertical state. The suction blocks c841 on the adsorption table fix the battery cover by means of vacuum pumping to prevent it from falling off. Then, the adsorption turntable c840 starts to rotate driven by the motor, conveys the battery cover to the point cover conveyor belt c100 for alignment with the tab on the battery, and finally, the welding is completed by the welding torch on the welding device c700.

[0072] Please refer to Figure 28, the quality inspection mechanism c900 includes a tension clamp c910 and a tension clamp driving device c920, both of which are located above the point cover conveyor belt c100. The tension clamp driving device c920 can be a cylinder or a motor, and is connected to the tension clamp c910 through a spring c930, so that the tension clamp c910 has a certain degree of buffering when clamping the battery cover, in order to better protect the integrity of the battery structure. In this embodiment, the tension clamp c910 is composed of two relatively arranged L-shaped blocks, and the opening and closing of the two L-shaped blocks are driven by a motor. In another embodiment, the two L-shaped blocks can be connected through an elastic structural member, such as a spring, and the two L-shaped blocks are locked by the tension generated by the spring. The structure at the connection between the L-shaped blocks adopts an arc transition. When the L-shaped blocks are driven down by a cylinder, the battery cover is clamped by squeezing the battery cover. When the L-shaped blocks rise, since the battery is stuck on the point cover battery slot c110, the L-shaped blocks will also disengage from the battery cover. Of course, at this time, the elastic force of the spring locking the L-shaped blocks should be just right, so that it can meet the detection quality while not taking the battery away from the point cover battery slot c110.

[0073] Please refer to Figure 23 , a pre-pressing mechanism c300 is also provided between the point cover battery feeding mechanism c200 and the point cover tab adjusting mechanism c400. The pre-pressing mechanism c300 includes a pre-pressing cylinder c310, a pressure rod c320 and a pressure block c330. The pre-pressing cylinder c310 and the pressure rod c320 are fixedly connected through a connecting plate c301, and the pressure block c330 is movably connected to the pressure rod c320 through an elastic member c302. When the chuck on the point cover battery feeding mechanism c200 clamps the battery onto the point cover battery slot c110, it may be affected by the debugging of the machine equipment or other environmental factors, resulting in the battery not being properly clamped or offset, or not being tightly clamped. Therefore, by adding the pre-pressing mechanism c300, the battery is further firmly and precisely clamped into the point cover battery slot c110 by pre-pressing, so as to facilitate subsequent further operations, thereby improving the yield rate of the product.

[0074] Please refer to Figure 25 , a short-circuit detection mechanism c500 is also provided between the point cover tab adjusting mechanism c400 and the tab bending mechanism c600. The short-circuit detection mechanism c500 includes a positive terminal c510 and a negative terminal c520. The above two terminals are respectively in contact with the negative and positive electrodes of the battery to measure whether the battery is short-circuited. If a short circuit occurs, the information is stored and sent to the subsequent process. The subsequent process determines whether to operate on the battery based on this information, so as to further improve the yield rate of the battery, reduce the battery rework rate, and also reduce the workload of the equipment.

[0075] Please refer to Figure 29, there is also a dust removal mechanism c1000 between the quality inspection mechanism c900 and the defective point cover discharging mechanism c1100. The dust removal mechanism c1000 includes a dust removal chamber c1010 and a dust removal cylinder c1020 for driving the lifting of the dust removal chamber c1010. During the welding or conveying process of the battery, it is easy to be contaminated with dust. If the amount of dust contamination is too large, there is a great possibility of causing a short circuit of the battery or other defective conditions. For example, it affects the quality of subsequent liquid injection or cover folding, resulting in impure quality during liquid injection, thus affecting the quality of the entire battery. In this embodiment, the dust removal chamber c1010 is in the form of a cavity and is a telescopic structure. When it presses down, it generates air pressure to suck away the dust. This method can, on the one hand, reduce the design cost of the equipment, and on the other hand, also play a role in correcting the battery cover. Of course, the dust removal chamber c1010 can also perform active dust removal by adding an air pump and an air pipe.

[0076] Please refer to Figure 30 , the defective point cover discharging mechanism c1100 includes a material receiving box c1110 and a material receiving clamp c1120. The material receiving clamp c1120 is also controlled by a cylinder and a motor to clamp the fixture, and clamps the defective products detected in its previous process to the material receiving box c1110 for recycling and reprocessing.

[0077] Please refer to Figure 21 and Figure 22 , there are vacancy induction devices c120 for detecting whether there is a battery in the point cover battery slot c110 at both the point cover battery feeding mechanism c200 and the point cover incoming material storage belt c20 of the point cover line transfer mechanism. Among them, the structure principle of the point cover incoming material storage belt c20 of the point cover line transfer mechanism is the same as that of the point cover battery feeding mechanism c200, that is, the qualified batteries welded on the point cover conveyor belt c100 are transferred to the next production line through the chuck. At the same time, there are also multiple vacancy induction devices c120 on the next production line to prevent there being empty battery positions. If an empty position is detected, the chuck will clamp a battery to fill the vacancy, thereby effectively improving the utilization rate of the battery positions.

[0078] The working process of the battery capping machine in this embodiment is as follows: First, the capping battery feeding mechanism c200 picks up and transfers the battery to be capped from the capping incoming material storage belt c10 to the capping battery slot c110 on the capping conveyor belt c100 of the capping machine, completing the feeding of the first step; Next, the pre-pressing mechanism c300 presses the battery to be capped, so that the battery is accurately and firmly clamped into the capping battery slot c110; Next, the capping tab adjusting mechanism c400 adjusts the directions of the battery tabs on the capping conveyor belt c100 to the same direction, facilitating the subsequent capping operation; Next, the short-circuit detection mechanism c500 detects whether the incoming battery is short-circuited, avoiding useless welding in the subsequent process; Next, the tab bending mechanism c600 bends the battery tabs. On the one hand, it facilitates the welding of the battery cover and the tabs, and on the other hand, it also avoids the tabs being knocked crooked due to position deviation when the battery cover comes in; Next, the capping operation is carried out. Among them, the source of the battery cover comes from the cover feeding device c800. After the cover feeding device c800 transfers the battery cover to the capping conveyor belt c100, it aligns with the battery tabs. After the alignment is completed, the welding device c700 is used for welding; Next, the quality detection mechanism c900 detects the welding quality; Next, the dust removal device removes dust. Finally, the products that are unqualified in the previous process are removed, and the qualified products are transferred to the next line. Thus, the entire operation process of the battery capping machine is completed.

[0079] The structure and working principle of the battery filling machine will be described below.

[0080] As Figures 33 - 35 shown, a battery filling machine includes a filling conveyor belt and a filling feeding device d100, a filling device d200, a vacuum pumping device d300, and a filling completion transfer device d400 arranged in sequence along the filling conveyor belt. The filling device d200 and the vacuum pumping device d300 are multiple corresponding ones, and the multiple filling devices d200 and vacuum pumping devices d300 are arranged alternately along the filling conveyor belt; The filling device d200 includes an injection machine d220 and a sealing cover d210. The sealing cover d210 is fixed on the filling conveyor belt, and the injection machine d220 is arranged inside the sealing cover d210. The injection machine d220 is provided with a positioning ring d222 and multiple filling heads d221. Both the positioning ring d222 and the filling heads d221 are driven by a filling cylinder d230, and the positioning ring d222 is located directly below the filling heads d221. In this embodiment, both the filling device d200 and the vacuum pumping device d300 are three corresponding ones, that is, it is divided into three times of filling and three times of vacuum pumping.

[0081] In the present invention, the battery is transferred to the liquid injection conveyor belt by the liquid injection and feeding device d100, and then the battery is injected with liquid by the liquid injection device d200. Immediately after injection, a vacuuming operation is performed, and the injection and vacuuming are repeated three times. After the injection and vacuuming are completed, the battery is transferred to the production line of the next production process, realizing the full automation of the battery injection operation. It should be noted that the number of times of injection and vacuuming can be determined according to the capacity of the battery, that is, the number of times of injection and vacuuming is determined according to the actual production effect and experience.

[0082] In this embodiment, since the electrolyte is flammable and prone to causing fires, the injection process is always completed in a closed space, reducing the pollution caused by the volatilization of the electrolyte in the air. By reducing the contact between the electrolyte and the outside world, the safety of the injection process is improved. The injection process of the battery is realized within the sealing cover d210. Therefore, a temperature controller can be set within the sealing cover d210 according to actual needs to achieve the purpose of real-time controlling the temperature within the sealing cover d210, and always maintaining the temperature within the sealing cover d210 at a fixed value, which can effectively improve the injection efficiency and installation performance. In addition, there are multiple injection heads d221 on the injection machine d220, and a positioning ring d222 is also provided below the injection head d221. The purpose is to, on the one hand, inject multiple batteries at one time to improve efficiency, and on the other hand, when injecting, the positioning ring d222 descends together with the injection head. The positioning ring d222 can first search and locate the position of the battery, and then perform injection after the positioning is completed, thereby improving the injection accuracy of the battery. The positioning ring d222 in this embodiment is provided with a position sensor and is elastically connected to the injection machine d220. Therefore, when it fails or is damaged, it can also have a certain buffering effect when accidentally touching the battery, avoiding damaging the battery.

[0083] As Figure 35 shown, the injection device in this embodiment further includes a first injection cylinder and a second injection cylinder. The first injection cylinder is connected to the injection machine d220 and is used to drive the lifting of the injection machine d220. The second injection cylinder is connected to the first injection cylinder, and the second injection cylinder is used to drive the horizontal movement of the second injection cylinder, thereby driving the horizontal movement of the injection machine d220.

[0084] As Figure 39 shown, the vacuuming device d300 in this embodiment is a conventional device, including a vacuum suction cup d310, a control cylinder d320, and a vacuum pump. During operation, the control cylinder d320 drives the vacuum suction cup d310 to press down. A vacuum sleeve is provided on the vacuum suction cup d310. After the vacuum sleeve is aligned with the battery, it is sleeved on the battery, and then the vacuum pump performs a vacuuming treatment on it.

[0085] As Figure 36 and Figure 37As shown, in this embodiment, the liquid injection feeding device d100 includes a liquid injection battery incoming material storage belt d110, a liquid injection feeding jig d120, and a liquid injection battery storage tray d130. The liquid injection battery storage tray d130 is slidably connected to the liquid injection conveyor belt 1. The liquid injection feeding jig d120 is used to clamp the batteries on the liquid injection battery incoming material storage belt d110 onto the liquid injection battery storage tray d130. The incoming material battery storage belt is used to store the semi-finished batteries from the previous process, and a battery vacancy sensor for sensing whether there is a battery is also provided on the incoming material battery storage belt. The liquid injection feeding jig d120 includes a liquid injection feeding gripper d121, a liquid injection feeding cylinder d123, and a liquid injection feeding slide rail d122. There are multiple liquid injection feeding grippers d121, and the number thereof corresponds to the number of battery vacancy sensors. The liquid injection feeding gripper d121 is driven by the liquid injection feeding cylinder d123 to move up and down. The opening and closing action of the liquid injection feeding gripper d121 can be driven by a cylinder or a motor. The liquid injection feeding cylinder d123 can slide along the liquid injection feeding slide rail d122. In this embodiment, multiple battery slots are provided on the liquid injection battery storage tray d130, and the multiple battery slots are arranged at uniform intervals in the horizontal and vertical directions on the surface of the liquid injection battery storage tray d130. The liquid injection feeding jig d120 clamps the batteries on the incoming material storage belt onto the battery slots, and stops when the battery slots of a liquid injection battery storage tray d130 are full.

[0086] As Figure 36 shown, in this embodiment, the liquid injection conveyor belt includes a transfer belt d11, a return belt d12, and a pusher device d13. The transfer belt d11 and the return belt d12 are arranged in parallel and have opposite conveying directions. There are two pusher devices d13, which are respectively located at the head and the tail of the transfer belt d11, and are used to push the liquid injection battery storage tray d130 to transfer between the transfer belt d11 and the return belt d12. In this embodiment, the liquid injection battery storage tray d130 is located at the head of the moving belt at the initial stage. At this time, the battery slots are filled with batteries. During movement, it passes through the liquid injection device d200 and the vacuum pumping device d300 in sequence, arrives at the end of the transfer belt d11, and then all the batteries are taken away by the liquid injection and transfer device d400. At this time, the liquid injection battery storage tray d130 is an empty tray. The empty tray is pushed by the pusher device d13 onto the return belt d12, and then conveyed back to the head of the transfer belt d11 by the return belt d12 to complete a round trip and prepare to load and unload the next batch of batteries to be injected with liquid.

[0087] As Figure 41As shown, in this embodiment, the transfer belt d11 and the return belt d12 have the same structure, both including a tape frame d610, on which there are driving rollers d620 and storage grooves d630. There are multiple driving rollers d620 which are connected in sequence. The driving rollers d620 are driven by a transmission device d640. The liquid-injected battery storage tray d130 is placed on the storage groove d630. When the liquid-injected battery storage tray d130 is placed on the storage groove d630, its bottom will contact the driving rollers d620. At this time, the driving rollers d620 are driven by the transmission device d640 to move, thereby driving the movement of the liquid-injected battery storage tray d130.

[0088] As Figure 42 shown, in this embodiment, the push plate device d13 includes a push plate cylinder d131 and a guide rail d132. The liquid-injected battery storage tray d130 can slide along the guide rail d132, and the push plate cylinder d131 is used to push the liquid-injected battery storage tray d130. The guide rail d132 is perpendicular to the transfer belt d11 and the return belt d12. When the liquid-injected battery storage tray d130 moves to the end of the transfer belt d11 or the end of the return belt d12, it can be limited by a clamping block to prevent it from detaching from the transfer belt d11 or the return belt d12. At this time, the push plate cylinder d131 pushes the liquid-injected battery storage tray d130 to move along the guide rail d132, so that the liquid-injected battery storage tray d130 is transferred from the transfer belt d11 to the return belt d12, or from the return belt d12 to the transfer belt d11.

[0089] As Figure 38 shown, in this embodiment, the liquid-injected and transferred material device d400 includes a liquid-injected and transferred material clamp d410 and a liquid-injected and transferred material belt d420. The liquid-injected and transferred material clamp d410 and the liquid-injected and transferred material belt d420 are both located at the end of the conveying direction of the liquid-injected conveyor belt. There are limiting clamp blocks d430 on the liquid-injected and transferred material belt d420. The limiting clamp blocks d430 are located above the liquid-injected and transferred material belt d420 and are used to correct the position of the battery. The liquid-injected and transferred material clamp d410 includes a liquid-injected and transferred material gripper d411. The liquid-injected and transferred material gripper d411 is driven by a liquid-injected and transferred material drive system d412 to rotate and lift. The drive system includes a rotary cylinder and a rotary motor. The lifting cylinder is used to drive the lifting of the liquid-injected and transferred material gripper d411, and the rotary motor is used to drive the rotation of the liquid-injected and transferred material gripper d411. It should be noted that the opening and closing of the liquid-injected and transferred material gripper d411 itself can also be realized by a motor or a cylinder. In addition, there are multiple grippers which are connected by a connecting block. At this time, the rotary motor drives the rotation of the entire connecting block, thereby driving the overall rotation of the multiple liquid-injected and transferred material grippers d411.

[0090] It should be noted that the limit clamping block d430 on the liquid injection completed transfer belt d420 is located directly above the liquid injection completed transfer belt d420. It is composed of two spaced limit plates, and a limit channel is formed between the two limit plates. The limit channel gradually decreases along the conveying direction of the liquid injection completed transfer belt d420, and the height position of the limit channel corresponds to the battery cover on the battery. That is, it is actually used to adjust the position of the battery cover so that the direction of each battery cover can be kept unified when the battery is finally discharged, facilitating further processing in subsequent processes.

[0091] This embodiment further includes a weighing device before liquid injection and a weighing device after liquid injection, which are respectively located at both ends of the liquid injection conveyor belt. The main purpose of this weighing system is to ensure that the mass of each battery during liquid injection is uniform. By recording the weight of each battery with the weighing device before liquid injection, and then recording the weight of the battery after liquid injection with the weighing device after liquid injection, a difference is set, and this difference is used to determine whether the liquid injection of the battery meets the standard, and the unqualified batteries are screened out as defective products and reprocessed, thus ensuring the liquid injection quality of the final battery.

[0092] As Figure 40 shown, therefore, this embodiment further includes a defective product discharging device d500 after liquid injection completion. The defective product discharging device d500 is located on the liquid injection completed transfer belt d420, and is used to discharge the unqualified batteries detected by the weighing device after liquid injection. The defective product discharging device d500 after liquid injection completion includes a discharging clamping head d510 after liquid injection completion, a discharging cylinder d520 after liquid injection completion, and a storage box d530. The discharging cylinder d520 after liquid injection completion is fixedly connected to the discharging clamping head d510 after liquid injection completion, and the storage box d530 is located on one side of the liquid injection completed transfer belt d420. Among them, there are two discharging cylinders d520 after liquid injection completion, one for driving the lifting of the discharging gripper, and the other for driving the translation of the discharging gripper.

[0093] The structure and working principle of the battery cover folding machine will be described below.

[0094] Please refer to Figure 43, A battery folding cover machine, including a folding cover conveyor belt e10, on which a folding cover battery slot e11 is fixedly provided. In the conveying direction of the folding cover conveyor belt e10, there are successively arranged a folding cover feeding mechanism e100, a battery cover alignment mechanism e200, a battery cover pressing mechanism, a detection mechanism, and a discharging mechanism e700. The battery cover alignment mechanism e200 includes a position sensor e210 and a battery rotation driving member e220. The position sensor e210 is located above the folding cover conveyor belt e10, and the battery rotation driving member e220 is located on the side of the folding cover conveyor belt e10. The battery cover pressing mechanism includes a battery cover bending device e300 and a battery cover stamping device e400 arranged successively along the conveying direction of the folding cover conveyor belt e10. In the present invention, the folding cover feeding mechanism e100 is used for feeding, clamping the battery to be folded onto the folding cover conveyor belt e10. Inevitably, during the clamping process, the battery may rotate, resulting in the deviation of the battery cover. The battery cover alignment mechanism e200 is used to adjust the direction of the battery cover to make the orientations of all battery covers consistent. The battery cover pressing mechanism is additionally provided with a battery cover bending device e300, which bends the battery cover to a state inclined at a certain angle with respect to the battery core, thus facilitating pressing and better protecting the battery. The detection mechanism excludes all batteries with the battery cover not pressed in place to ensure that the batteries transmitted to the product line of the next process are qualified products, reducing the defective rate of the final product.

[0095] Please refer to Figure 44 , In this embodiment, the battery folding cover feeding mechanism e100 includes a folding cover feeding gripper e110. The folding cover feeding gripper e110 controls the lifting movement and opening / closing of the gripper through a folding cover feeding motor e130 and a folding cover feeding air cylinder e120 respectively. Its specific structure and implementation method are all conventional applications of the prior art and will not be described in detail here. The specific manifestation of the feeding process is that the battery enters from the folding cover incoming material belt e2 of the previous process, and there is a vacancy sensor at the end of the folding cover incoming material belt e2. When a battery is sensed, the folding cover feeding gripper e110 clamps the incoming battery onto the battery slot of the folding cover conveyor belt e10 to complete the feeding. Moreover, there is also a vacancy sensor at the starting end of the folding cover conveyor belt e10 to prevent missing the clamping of the battery and affecting the efficiency. After the feeding is completed, the folding cover conveyor belt e10 conveys the incoming battery to the next process, that is, to the battery cover alignment mechanism e200 for processing.

[0096] Please refer to Figure 45, in this embodiment, the battery cover correction mechanism e200 includes a position sensor e210 and a battery rotation driving member e220. Among them, the battery rotation driving member e220 includes a positioning wheel e221, an adjustment wheel e222, and an adjustment wheel control system e223. The positioning wheel e221 is driven to translate by a positioning cylinder e2212. The adjustment wheel control system e223 is used to control the movement and rotation of the adjustment wheel e222. The positioning wheel e221 and the adjustment wheel e222 are respectively arranged on opposite sides of the folding cover conveyor belt e10. Specifically, in this embodiment, there are two positioning wheels e221. The two positioning wheels e221 are fixed on a positioning plate e2211. The positioning plate e2211 is slidably connected to a fixed platform e2213 arranged on one side of the folding cover conveyor belt e10. The positioning cylinder e2212 and the positioning plate e2211 are both arranged on the fixed platform e2213. The positioning cylinder e2212 can drive the movement of the positioning plate e2211 so that the positioning wheel e221 contacts the battery. The two positioning wheels e221 respectively contact both sides of the battery, which can prevent the offset of the battery. The adjustment wheel e222 is arranged on the other side of the folding cover conveyor belt e10 opposite to the positioning plate e2211. The adjustment wheel e222 can contact the battery through the drive of a cylinder, and then drive the rotation of the battery by driving its rotation with a motor, and perform corresponding adjustments according to the information transmitted by the position sensor e210, so as to achieve the purpose of adjusting the direction of the battery cover. The sensor can be a fiber optic sensor or other sensors for sensing the position of an object.

[0097] The advantage of the above-mentioned battery cover correction mechanism e200 is that it makes the quality of the battery cover more uniform during the subsequent pressing process and after pressing. Since the subsequent pressing mechanism generally repeats the same action continuously, the pressure direction and pressure point of the pressing mechanism are consistent. When the directions of the battery covers are not unified, it is easy to cause inconsistent stress points of the battery covers during pressing. And the battery cover and the battery core ear are already welded in the previous steps. If there is a certain deviation in the stress point of the battery cover, there is a high possibility of causing the deformation of the ear. Therefore, by correcting the direction of the battery cover through the battery cover correction mechanism e200, the above problems can be effectively avoided and the quality of the capping can be improved.

[0098] Please refer to Figure 46, in this embodiment, the battery cover pressing mechanism includes a battery cover bending device e300 and a battery cover stamping device e400. Among them, the battery cover bending mechanism includes a locking fixture e310, a bending gripper e320, and a bending gripper control system e330. The locking fixture e310 is located on the side of the cover folding conveyor belt e10, the bending gripper e320 is located above the cover folding conveyor belt e10, and the bending gripper control system e330 is used to control the lifting and opening / closing of the bending gripper e320, which can be achieved through the cooperation of a cylinder and a motor. Specifically, the locking fixture e310 includes a locking plate e311 and a locking cylinder e312. The locking plate e311 is fixedly connected to the driving rod of the locking cylinder e312. A groove e3111 is provided on the side of the locking plate e311 facing the cover folding conveyor belt e10. The groove e3111 matches the battery, and both the locking plate e311 and the locking cylinder e312 are two and are symmetrically arranged on both sides of the cover folding conveyor belt e10. When the battery is transported to the battery cover bending device e300 and the battery cover needs to be bent, the battery is first locked by the locking device to prevent its offset during bending. Then, the bending gripper clamps the battery cover and bends it to an inclined state at a certain angle with the battery cell. The advantage is that when the battery cover is stamped subsequently, it can be accurately pressed on the top surface of the battery cover rather than the side surface, thereby improving the success rate of battery cover pressing while ensuring the pressing quality and reducing the damage to the battery.

[0099] Please refer to Figure 47 , after the bending operation of the battery cover, the battery cover needs to be pressed. The battery cover stamping device e400 of this embodiment includes a stamping cylinder e410, a pressure rod e420, and a pressing die cavity e430. The pressure rod e420 is fixedly connected to the driving rod of the stamping cylinder e410. A through hole e431 is provided on the pressing die cavity e430, and the through hole e431 matches the pressure rod e420 and the battery. Specifically, the pressing die cavity e430 is controlled by a cylinder to achieve its translation and lifting. During pressing, the pressing die cavity e430 is located above the battery on the cover folding conveyor belt e10, and the battery cover passes through the through hole e431 of the pressing die cavity e430, so that the pressure rod e420, the battery, and the through hole e431 are on the same vertical line, which is convenient for pressing. Among them, multiple through holes e431 can be provided on the pressing die cavity e430, and the number of pressure rods e420 should also be the same as that of the through holes e431, so as to improve the pressing efficiency. Through the setting of the pressing die cavity e430, the success rate of pressing can be further ensured. The battery cover during pressing is always located within the through hole e431. Therefore, even if the position of the battery cover has a certain deviation during pressing, it can be corrected through the through hole e431, which not only avoids the detachment of the battery cover but also improves the pressing quality, making the alignment of the battery cover and the battery housing more accurate.

[0100] Please refer to Figure 48, after the lamination is completed, it is necessary to detect the lamination quality. The detection mechanism in this embodiment includes a battery cover induction device e500 and a defective cover discharging device e600. The battery cover induction device e500 and the defective cover discharging device e600 are arranged in sequence along the conveying direction of the cover folding conveyor belt e10. Among them, the battery cover induction device e500 includes an induction block e510 and an induction block driving cylinder e520. The induction block e510 and the induction block driving cylinder e520 are movably connected through a connecting piece e530. The connecting piece e530 is provided with an elastic member, such as a spring e540. The induction block is used to detect the lamination state of the battery cover. Specifically, when the cover folding conveyor belt e10 conveys the laminated battery to below the induction block, the induction block driving cylinder e520 drives the induction block to move down. When the induction block e510 touches the battery cover, the current state of the battery cover can be obtained by acquiring information such as the position of the battery cover and the contact area with the battery cover, so as to confirm whether it has shifted or is not laminated properly. Of course, it can also be determined by infrared scanning to obtain the surface shape of the battery cover. The detection results are recorded and the corresponding unqualified products are excluded by the defective cover discharging device e600.

[0101] Please refer to Figure 49 , the defective cover discharging device e600 in this embodiment includes a material removing gripper e610 and a defective material tank e620. The material removing gripper e610 controls the lifting, moving and opening / closing of the material removing gripper e610 through a cylinder and a motor respectively. The defective material tank e620 is arranged on one side of the cover folding conveyor belt e10 and is used to store the products with unqualified quality sensed by the induction device. The qualified products will continue to be conveyed to the discharging mechanism e700. The structure of the discharging mechanism e700 is the same as that of the feeding mechanism. A battery vacancy induction device e3 for sensing whether there is a battery in the battery slot is also provided at the discharging mechanism e700.

[0102] Please refer to Figure 50 and Figure 51 , in this embodiment, the cover folding machine further includes a sealing device e800. The sealing device e800 is connected to the discharging mechanism e700. The sealing device e800 includes a sealing press block e810 and a fixed clamp block e820. The fixed clamp block e820 is used to fix the battery. The sealing press block e810 is located above the fixed clamp block e820. An elastic buffer e830 is also provided on the sealing press block e810, which is used as a buffer during lamination and can also play a role in resetting to a certain extent. The purpose of sealing is to further combine the battery cover and the battery case to make their combination tighter.

[0103] The working process of the folding cover machine of the present invention is as follows: The folding cover loading mechanism e100 clamps the battery to be folded from the folding cover incoming material belt e2 onto the battery card slot of the folding cover conveyor belt e10. At the same time, before and after clamping, the empty position sensing device e3 is used to detect whether it is a valid clamping. The battery clamped onto the folding cover conveyor belt e10 is adjusted by the battery cover adjustment mechanism so that the orientation of each battery cover is kept consistent. The adjusted battery is bent by the battery cover bending mechanism to make it inclined at a certain angle with the battery core, and then is pressed by the battery cover stamping device e400. After the pressing is completed, the pressing quality is detected by the sensing device, and the detected unqualified products are excluded by the folding cover defective product discharging device e600. Finally, the qualified products are transferred to the sealing device e800 by the discharging mechanism e700 for further sealing operation, thus completing the folding cover process of the battery case and the battery cover.

[0104] The structure and working principle of the battery cleaning machine will be described below.

[0105] Please refer to Figures 52 - 53 As shown in the figure, the present invention provides a battery cleaning machine, which is mainly used for cleaning the battery after injection and sealing to avoid the electrolyte adhered to the surface of the battery from polluting the battery during subsequent processing.

[0106] Specifically, the battery cleaning machine mainly includes a cleaning mechanism f100, an oiling mechanism f200, and a cleaning conveyor belt f300. Among them, the cleaning mechanism f100 is mainly used for cleaning the battery, the oiling mechanism f200 is mainly used for oiling the battery after cleaning, and the cleaning conveyor belt f300 sequentially passes through the cleaning mechanism f100 and the oiling mechanism f200. The cleaning conveyor belt f300 is mainly used for transporting the battery, especially for transporting the battery to the positions corresponding to the cleaning mechanism f100 and the oiling mechanism f200 in sequence for cleaning and oiling processing procedures.

[0107] Among them, the cleaning mechanism f100 mainly includes a primary cleaning tank f110, a secondary cleaning tank f120, and a tertiary cleaning tank f130 sequentially arranged on the cleaning conveyor belt f300. The three cleaning tanks of the present invention clean the battery with different solutions. The primary cleaning tank f110 is used for the first cleaning of the battery with hot water, the secondary cleaning tank f120 is used for the second cleaning of the battery with clean water, and the tertiary cleaning tank f130 is used for the third cleaning of the battery with pure water.

[0108] In the present invention, the battery is cleaned sequentially with hot water, fresh water, and pure water. The battery in its initial state is cleaned with hot water. At this time, the degree of surface contamination of the battery is the highest, and the stains are easily soluble in hot water. The battery is cleaned to the greatest extent by the first cleaning tank f120. Then, the second cleaning tank f120 cleans the battery with normal-temperature fresh water. The fresh water can be at normal temperature, and at the same time, the fresh water is used to cool down the battery. Finally, the third cleaning tank f130 cleans the battery with pure water. Since the chemical purity of the pure water is extremely high, the battery is further cleaned with pure water after being cleaned twice, greatly improving the cleanliness of the battery. At the same time, because the battery has been cleaned twice before, the contamination has been greatly reduced. Therefore, the pure water in the third-stage cleaning tank f130 can support a longer service time, thereby reducing the loss of production raw materials and the production cost.

[0109] For specific applications, please refer to Figure 55 As shown, the first cleaning tank f110, the second cleaning tank f120, and the third cleaning tank f130 have the same structure. All three include a tank body f111, a water suction pipe f112 arranged at the bottom of the tank body f111, a water spray pipe f113 arranged at the top of the tank body f111, and a cleaning pump f1f14. The water spray pipe f113 is located above the cleaning conveyor belt f300, that is, the battery is transported under the water spray pipe f113. The water spray openings of the water spray pipe f113 face downward. The cleaning pump f1f14 is respectively connected to the water suction pipe f112 and the water spray pipe f113. The cleaning pump f1f14 extracts the cleaning solution at the bottom of the tank body f111 through the water suction pipe f112 and then sprays it onto the battery located on the cleaning conveyor belt f300 through the water spray pipe f113 to achieve the cleaning effect. Among them, a heating device for heating the cleaning solution, such as a heating wire, is arranged in the first cleaning tank f110. The cleaning solution is heated through this heating device, for example, heating fresh water to obtain hot water.

[0110] To enhance the cleaning effect, the first cleaning tank, the second cleaning tank, and the third cleaning tank also include cleaning brushes f1f15 rotatably arranged in the tank body f111 and corresponding to the cleaning conveyor belt f300. The number of the cleaning brushes f1f15 is multiple, and the multiple cleaning brushes f1f15 are arranged along the extending direction of the cleaning conveyor belt f300. The battery is brushed by the cleaning brushes f1f15 to make the cleaning of the battery more thorough.

[0111] Please continue to refer to Figure 54 and Figure 55As shown, the cleaning mechanism f100 further includes a circulation component f140 that is simultaneously connected to the primary cleaning tank f110, the secondary cleaning tank f120, and the tertiary cleaning tank f130. The circulation component f140 is used for the water circulation of the primary cleaning tank f110, the secondary cleaning tank f120, and the tertiary cleaning tank f130. For example, the circulation component f140 transports the used pure water in the tertiary cleaning tank f130 to the primary cleaning tank f110 or the secondary cleaning tank f120. Another example is that the circulation component f140 transports the used clear water in the secondary cleaning tank f120 to the primary cleaning tank f110. Since the cleaning precisions corresponding to the primary cleaning tank f110, the secondary cleaning tank f120, and the tertiary cleaning tank f130 are different, the used pure water in the tertiary cleaning tank f130 is transported to the primary cleaning tank f110 or the secondary cleaning tank f120 for secondary use through the circulation component f140, and the used clear water in the secondary cleaning tank f120 is transported to the primary cleaning tank f110 for secondary use, and then discharged through the primary cleaning tank f110. In this way, the maximum recycling of the cleaning solution is achieved, the material utilization rate is improved, and the production cost is reduced.

[0112] In specific applications, the circulation component f140 includes connecting pipes for respectively connecting the primary cleaning tank f110, the secondary cleaning tank f120, and the tertiary cleaning tank f130. Switch valves corresponding to the primary cleaning tank f110, the secondary cleaning tank f120, and the tertiary cleaning tank f130 are provided on the connecting pipes to control the circulation flow direction of the cleaning solution between the three cleaning tanks through the corresponding switch valves. It should be specifically noted that the connecting pipes are also directly connected to the pure water source, and the feeding and recycling of pure water are directly realized through the connecting pipes.

[0113] In one embodiment, please continue to refer Figure 52 to Figure 53 As shown, the cleaning mechanism f100 further includes a cleaning feeding device f150 arranged on one side of the primary cleaning tank f110. The cleaning feeding device f150 is used for feeding the battery onto the cleaning conveyor belt f300.

[0114] In specific applications, the cleaning feeding device f150 includes a feeding linear module f151, a feeding lifting driving element f152, and a feeding clamp f153. The feeding linear module f151 drives the feeding lifting driving element f152 to move linearly above the cleaning conveyor belt f300. The feeding clamp f153 is used for clamping the battery. The feeding clamp f153 is arranged on the feeding lifting driving element f152, and the feeding lifting driving element f152 drives the feeding clamp f153 to move vertically to clamp the battery with the feeding clamp f153, thereby realizing the feeding of the battery onto the cleaning conveyor belt f300.

[0115] Please continue to refer Figure 52 toFigure 53 As shown, the battery is generally transported in a horizontal placement manner, while when the incoming materials arrive, the battery is generally placed vertically. Therefore, in order to use the above-mentioned incoming production materials method, the cleaning mechanism f100 of the present invention further includes a feeding rotation device f160 disposed between the cleaning feeding device f150 and the cleaning conveyor belt f300. The feeding rotation device f160 is used to rotate the battery and place it on the cleaning conveyor belt f300. Specifically, the feeding rotation device f160 includes a rotation bracket f161, a rotation carrier f162 rotatably disposed on the rotation bracket f161, a rotation driving element f163 for driving the rotation carrier f162 to rotate, and a rotation push plate for pushing the battery out of the rotation carrier f162. When the cleaning feeding device f150 feeds the battery, the cleaning feeding device f150 clamps the battery onto the rotation carrier f162, and then the rotation driving element f163 drives the rotation carrier f162 to rotate, rotating the battery to a horizontal placement state and corresponding to the position of the cleaning conveyor belt f300. Then the rotation push plate pushes the battery out of the rotation carrier f162 onto the cleaning conveyor belt f300, realizing the conversion of the vertically placed battery into a horizontal placement state.

[0116] Among them, the cleaning mechanism f100 further includes a cleaning and drying furnace f170 disposed on one side of the three-stage cleaning tank f130. The cleaning and drying furnace f170 is used to dry the battery that has completed three-stage cleaning. Additionally, it is worth noting that the cleaning mechanism f100 further includes a laser engraving machine 180 disposed on the side of the cleaning and drying furnace f170 away from the three-stage cleaning tank f130. The laser engraving machine 180 performs laser engraving on the dried battery, enriching the functions of the battery cleaning machine of the present invention.

[0117] Please refer to Figure 52 and Figure 56 As shown, the oiling mechanism f200 of the present invention includes an oil spraying furnace f210, an oiling drying furnace f220, and a cleaning and discharging device f230 arranged in sequence. The oil spraying furnace f210 is mainly used to spray anti-rust oil on the battery, the oiling drying furnace f220 is mainly used to dry the battery that has completed spraying anti-rust oil, and the cleaning and discharging device f230 is located at the end of the cleaning conveyor belt f300 and is used to discharge the battery that has completed oiling and drying to a preset position. By sequentially oiling and drying the battery through the oil spraying furnace f210 and the oiling drying furnace f220, spraying anti-rust oil enables the battery to have excellent resistance performance during subsequent use.

[0118] Please refer to together Figure 54As shown, in the present invention, in order to make the battery have better effects during the cleaning process and the oiling process, a plurality of rotating roller shafts 310 that are sequentially meshed and rotatably arranged in the same direction are provided in the middle of the cleaning conveyor belt f300. One of the rotating roller shafts 310 is driven to rotate through gears, so as to drive all the rotating roller shafts 310 to rotate simultaneously. When the cleaning conveyor belt f300 transports the battery, the battery is placed on the plurality of rotating roller shafts 310, so that the battery rotates with the rotation of the rotating roller shafts 310 during the transportation process. In this way, the battery rotates along its central axis while being transported on the cleaning conveyor belt f300, so that the battery continuously rotates when being cleaned and oiled in the cleaning mechanism f100 and the oiling mechanism f200 respectively, greatly enhancing the cleaning effect and the uniformity of oiling, and further effectively improving the processing effect of the battery cleaning machine of the present invention on the battery and improving the product quality.

[0119] For specific applications, please refer to Figure 56 and Figure 57 As shown, the cleaning and blanking device f230 includes a rotating turntable f231, a rotating driving element f232, a blanking push rod f233 and a blanking driving element f234. The rotating turntable f231 is vertically arranged at the end of the cleaning conveyor belt f300. A plurality of material conveying grooves f2311 are formed on the edge of the rotating turntable f231. The blanking push rod f233 is arranged on one side of the rotating turntable f231. The rotating driving element f232 drives the rotating turntable f231 to rotate, so that the plurality of material conveying grooves f2311 alternately move to correspond to the blanking push rod f233, so that the battery on the cleaning conveyor belt f300 is transported to the corresponding position of the blanking push rod f233 through the material conveying grooves f2311. Then the blanking driving element f234 drives the blanking push rod f233 to pass through the material conveying grooves f2311, and then pushes the battery out of the material conveying grooves f2311 to a preset position, realizing automatic blanking of the battery. Additionally, it is worth noting that the cleaning and blanking device f230 further includes a limiting plate f235 arranged on the rotating turntable f231. The shape of the limiting plate f235 corresponds to that of the rotating turntable f231. The limiting plate f235 is located between the cleaning conveyor belt f300 and the blanking push rod f233. The limiting plate f235 is fixed relative to the rotating turntable f231. When the rotating turntable f231 rotates through the part of the limiting plate f235, the two sides of the rotating turntable f231 are blocked by the limiting plate f235, so as to prevent the battery from falling off the material conveying grooves f2311, effectively ensuring the stability of the blanking process of the cleaning and blanking device f230 for the battery.

[0120] The working principle of the cleaning machine of the present invention is as follows: The cleaning and loading device f150 clamps the battery and transports it to the loading and rotating device f160. Then, the battery is rotated by the loading and rotating device f160 and placed on the cleaning conveyor belt f300. Then, the cleaning conveyor belt f300 transports the battery to the first-stage cleaning tank f110, the second-stage cleaning tank f120, and the third-stage cleaning tank f130 in sequence for hot water cleaning, clean water cleaning, and pure water cleaning respectively. Then, the battery is dried through the cleaning and drying furnace f170. Next, the cleaning conveyor belt f300 transports the battery to the oil spraying furnace f210 and the oil coating and drying furnace f220 of the oil coating mechanism f200 in sequence for spraying anti-rust oil and drying respectively. Finally, it is transported to the cleaning and unloading device f230 to unload the battery to a preset position.

[0121] In summary, the battery cleaning machine of the present invention is provided with a first-stage cleaning tank, a second-stage cleaning tank, and a third-stage cleaning tank to achieve three-stage cleaning of the battery, greatly improving the cleaning effect of the battery; the battery cleaning machine is also provided with a circulation component respectively communicating with the first-stage cleaning tank, the second-stage cleaning tank, and the third-stage cleaning tank to realize water circulation utilization, which is more energy-saving and environmentally friendly and reduces production costs; the battery cleaning machine is also provided with an oil coating mechanism for coating the battery to realize timely spraying of anti-rust oil on the battery after cleaning, greatly improving the anti-rust performance of the battery during subsequent use.

[0122] The structure and working principle of the battery sealing machine will be described below.

[0123] Please refer to Figure 58 As shown in the figure, a battery sealing machine includes a conveyor belt g100 for transporting the battery to be processed, a sealing device g200, a sealing detection device g400, a blue shell paper laminating device g300, a vacancy detector g500, a lamination detection device g600, and a cleaning wheel g700, which are sequentially connected by the conveyor belt g100.

[0124] Please also refer to Figures 58 - 60 、 Figures 64 - 66As shown in the figure, the pier sealing device g200 includes two pier sealing clamps g201, one pier sealing pressing block g202, and one pier sealing cylinder g203. The two pier sealing clamps g201 are respectively connected to the conveying belt g100, and the pier sealing actions of two batches of batteries to be processed can be carried out simultaneously. There is only one pier sealing pressing block g202 and it is arranged above the pier sealing clamp g201. There is also only one pier sealing cylinder g203, which drives the pier sealing pressing block g202 to move upward to achieve the pier sealing action on the batteries to be processed. The two pier sealing clamps g201 have the same composition structure. One pier sealing cylinder g203 is connected to the conveying belt g100 through the feeding channel g204 and the discharging channel g206. The feeding cylinder g205 drives the batteries to be processed to reach the pier sealing clamp g201 from the conveying belt g100 via the feeding channel g204, and the discharging cylinder g207 drives the batteries to be processed to reach the conveying belt g100 from the pier sealing clamp g201 via the discharging channel g206.

[0125] The pier sealing clamp g201 is formed by enclosing the left clamp block g208 and the right clamp block g209. The opening and closing of the pier sealing clamp g201 are driven by the clamp cylinder g210. The left clamp block g208 has a semi-circular left groove g211 facing the right clamp block g209, and the right clamp block g209 has a semi-circular right groove g212 facing the left clamp block g208. The clamp cylinder g210 pushes the right clamp block g209 to move. When the right clamp block g209 and the left clamp block g208 are closed together, the semi-circular left groove g211 and the semi-circular right groove g212 form a cylindrical cavity, which confines the battery to be processed in this cylindrical cavity. There is a gentle slope g213 on the left clamp block g208. When the battery to be processed enters the semi-circular left groove g211 from the feeding channel g204, the battery to be processed will contact the gentle slope g213 and smoothly reach the semi-circular left groove g211 along the slope of the gentle slope g213.

[0126] Please refer to Figure 58 、 Figure 59 、 Figure 64 and Figure 70 As shown in the figure, the pier sealing detection device g400 is located on the conveying belt g100 between the pier sealing device g200 and the blue shell paper laminating device g300. The pier sealing detection device g400 includes a cylindrical cavity g401 connected to the conveying belt g100, a circular chuck g402 located inside the cylindrical cavity g401, a motor g403 that drives the circular chuck g402 to rotate, and a sensor g404 located beside the circular chuck g402. The sensor is a GT-H10 displacement sensor produced by Keyence Corporation. There is a semi-circular groove g405 on the circular chuck g402 for cooperating with the side wall of the cylindrical cavity g401 to clamp the battery to be processed. The battery to be processed is stuck in the space surrounded by the semi-circular groove g405 and the side wall of the cylindrical cavity g401, and rotates with the rotation of the circular chuck g402. Figure 13Only a partial cavity wall of the cylindrical cavity g401 is drawn. When the battery to be processed is rotated to the bottom of the GT-H10 displacement sensor, the GT-H10 displacement sensor detects the battery to be processed and determines the sealing effect. A defective product channel g406 is set next to the sealing detection device g400, and a defective product grabbing cylinder g407 is set on the defective product channel g406. When it is detected that the battery has a poor sealing effect, the battery is grabbed by the defective product grabbing cylinder g407 and put into the defective product channel g406.

[0127] Please refer to Figure 58 , Figures 61 - 63 as well as Figure 69 As shown, when it is detected that the sealing effect of the battery is good, it enters the next station for green shell paper lamination. The green shell paper laminating device g300 includes a turntable g301 connected to the conveyor belt g100, a punching laminating machine g302 located above the turntable g301, a discharge roller g303 that provides green shell paper raw materials to the punching laminating machine g302, and two reeling rollers g304 that collect green shell paper waste for the punching laminating machine g302. One side of the green shell paper is sticky and affixed with release paper. A roll of unused green shell paper is placed in the discharge roller. The end of the green shell paper is pulled to extend the green shell paper and pass through the punching laminating machine g302. After the green shell paper passes through the punching laminating machine g302, the release paper is separated from the green shell paper and collected in the two reeling rollers respectively.

[0128] Please refer to Figure 67 and Figure 68As shown in the figure, after the battery is pasted with the black shell paper, it is necessary to perform inspection and cleaning. The inspection is carried out by the empty position detector g500 and the bonding detection device g600, and the cleaning is achieved by the cleaning wheel g700. The empty position detector g500, the bonding detection device g600, and the cleaning wheel g700 are all arranged above the turntable g301. The turntable g301 has four workstations arranged in sequence, which are the empty position detector g500, the black shell paper bonding device g300, the bonding detection device g600, and the cleaning wheel g700 arranged in sequence. The empty position detector g500 and the bonding detection device g600 are both realized by using existing sensors that can be purchased on the market. Among them, the empty position detector g500 can ensure that the turntable g301 holds a battery instead of an empty position, and the bonding detection device g600 can determine whether the black shell paper is adhered to the positive electrode of the battery. After the detection is completed, the cleaning wheel rotates to sweep the dust on the black shell paper to keep the product clean. The conveying tape g100 includes a vertical tape and a horizontal tape. One part of the turntable g301 is connected to the vertical tape, and the other part is connected to the horizontal tape through the flipping channel g800. The flipping channel g800 is dug with a spiral groove g801. The conveying tape after the cleaning wheel workstation adopts a horizontal tape, and the conveying tape in the remaining areas adopts a vertical tape. After the battery is cleaned, it enters the flipping channel g800 in a vertical state, and the battery gradually lies flat along the spiral groove g801 in the flipping channel g800. Finally, the battery becomes in a horizontal state and is output along the horizontal tape.

[0129] The structure and working principle of the battery discharger will be described below.

[0130] Please refer to Figures 71 - 74 As shown in the figure, the present invention provides a battery discharger, which is mainly used for automatically discharging the battery. Specifically, the battery discharger mainly includes a discharging annular transportation line h100, a discharging loading mechanism h200, a discharging unloading mechanism h300, and a discharging mechanism h400. Among them, the discharging annular transportation line h100 is mainly used for transporting and recycling the molds for loading the batteries, and the batteries are loaded in the molds and transported on the discharging annular transportation line h100. The discharging loading mechanism h200 and the discharging unloading mechanism h300 are arranged on the two outer sides of the discharging annular transportation line h100. In particular, the discharging loading mechanism h200 and the discharging unloading mechanism h300 are respectively arranged at both ends of the discharging annular transportation line h100, which can reduce the mutual interference between the two. Among them, the discharging loading mechanism h200 is mainly used for automatically loading the batteries onto the discharging annular transportation line h100, especially loading the batteries into the molds located on the discharging annular transportation line h100. The discharging unloading mechanism h300 is used for automatically unloading the batteries that have completed the discharging process to the corresponding positions, and the discharging mechanism h400 is arranged between the discharging loading mechanism h200 and the discharging unloading mechanism h300. The discharging mechanism h400 is mainly used for discharging the batteries.

[0131] In specific applications, the discharging and loading mechanism h200 mainly includes a loading device h201, a loading turntable h202, a height measuring device h203, a defective screening device h204, and a loading transfer device h205. Among them, the loading device h201, the height measuring device h203, the defective screening device h204, and the loading transfer device h205 are arranged around the loading turntable h202. A plurality of loading jigs h2021 for loading batteries are provided on the loading turntable h202. The loading turntable h202 rotates to switch the plurality of loading jigs h2021 in the circumferential track direction. The loading device h201 loads the batteries into the loading jigs h2021 of the loading turntable h202. Then, the loading turntable h202 rotates to transport the batteries to the positions corresponding to the height measuring device h203, the defective screening device h204, and the loading transfer device h205 in sequence. The height measuring device h203 measures the height of the batteries. The defective screening device h204 takes out the batteries with defective height measurement and places them at a preset recycling point for recycling. The loading transfer device h205 transfers the qualified batteries into the discharging annular transportation line h100. In this way, the height of the loaded batteries is tested, and the batteries with defective height are screened, ensuring that the height of the batteries transported to the discharging mechanism h400 for discharging treatment meets the standard, thereby reducing the inflow of defective discharged products into the post-processing process and improving the production quality.

[0132] When the battery discharging machine of the present invention is working, the loading device h201 loads the batteries into the loading jigs h2021 of the loading turntable h202. Then, the loading turntable h202 rotates to transport the batteries to the positions corresponding to the height measuring device h203, the defective screening device h204, and the loading transfer device h205 in sequence. The height measuring device h203 measures the height of the batteries. The defective screening device h204 takes out the batteries with defective height measurement and places them at a preset recycling point for recycling. The loading transfer device h205 transfers the qualified batteries into the mold of the discharging annular transportation line h100 for transportation. When the batteries are transported to the position corresponding to the discharging mechanism h400, the discharging mechanism h400 performs discharging treatment on the batteries. Then, the batteries that have completed the discharging treatment are transported to the discharging and unloading mechanism h300 for unloading through the discharging annular transportation line h100.

[0133] In the present application, the discharge ring-shaped transport line h100 is composed of two linear transport lines h101 that are parallel to each other and two processing transport lines h102 that connect the two linear transport lines h101 end to end. The linear transport line h101 is used for linearly transporting batteries. The two processing transport lines h102 correspond to the discharge loading mechanism h200 and the discharge unloading mechanism h300 respectively. Specifically, two transport push plates h103 are also arranged between the linear transport line h101 and the processing transport line h102. One transport push plate h103 is used to push the mold from the linear transport line h101 into the processing transport line h102, and the other transport push plate h103 is used to push the mold from the processing transport line h102 out to the linear transport line h101. At the same time, through the cooperation of the two transport push plates h103, the transport of the mold on the processing transport line h102 is realized.

[0134] In one embodiment, please continue to refer to Figure 72 As shown, the loading device h201 includes a loading movement driving element h2011, a loading lifting driving element h2012, and a loading clamping assembly h2013. The loading movement driving element h2011 is arranged above the loading turntable h202. The loading lifting driving element h2012 is arranged on the loading movement driving element h2011. The loading clamping assembly h2013 is arranged at the bottom of the loading lifting driving element h2012. The loading movement driving element h2011 drives the loading lifting driving element h2012 to linearly move above the loading turntable h202. The loading lifting driving element h2012 drives the loading clamping assembly h2013 to vertically lift and move. The loading clamping assembly h2013 is used to clamp the battery, so as to realize the transportation of the battery from the preset position to the loading turntable h202. In the present application, the battery discharger of the present invention may further include a loading transport line arranged on one side of the loading turntable h202. This loading transport line is used to transport the batteries to be subjected to discharge treatment. The loading movement driving element h2011 is arranged above the loading turntable h202 and the above-mentioned loading transport line.

[0135] In one embodiment, please continue to refer to Figure 73As shown, the height measuring device h203 includes a height measuring bracket h2031, a height measuring driving element h2032, and a height measuring sensor h2033. The height measuring bracket h2031 is directly disposed on one side of the loading turntable h202. The height measuring driving element h2032 is disposed on the height measuring bracket h2031. When the battery is transported on the loading turntable h202 to the position corresponding to the height measuring device h203, the height measuring driving element h2032 drives the height measuring sensor h2033 to move vertically towards the loading turntable h202, and the battery is height-measured by the height measuring sensor h2033. For example, the height measuring sensor h2033 can adopt a pressure sensor. When using the pressure sensor for height measurement, the pressure sensor moves a preset distance. When the height of the battery meets the requirement, the pressure value obtained by the pressure sensor is within the preset range. When the height of the battery does not meet the requirement, the pressure value obtained by the pressure sensor is less than the preset range. Of course, the height measuring sensor h2033 can also adopt other sensors that can be used to measure distance, such as an infrared distance measuring sensor. Additionally, it should be noted that the height measuring device further includes a support driving element h2034 and a support plate h2035. The support driving element h2034 is disposed on the height measuring bracket h2031, and the support plate h2035 is disposed on the top of the support driving element h2034 and is located below the loading turntable h202. When the height measuring sensor h2033 adopts a pressure sensor, to avoid tilting caused by the pressure of the height measuring sensor h2033 on the loading turntable h202 during height measurement, the support driving element h2034 drives the support plate h2035 to move vertically towards the loading turntable h202, and the bottom of the loading turntable h202 is supported by the support plate h2035 to prevent the loading turntable h202 from tilting, thereby avoiding affecting the processing of other workstations and ensuring the stability of the equipment operation.

[0136] In one embodiment, please continue to refer to Figure 72 and Figure 74As shown, the defective screening device h204 includes a defective discharging conveyor line h2041, a screening moving drive element h2042, a screening lifting drive element h2043, and a screening plate h2044. The defective discharging conveyor line h2041 is arranged on one side of the loading turntable h202 and is used to transport the height-measurement defective products to the corresponding discharging positions.
