Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and in particular to a new energy battery sheet feeding mechanism. Background Art

[0002] New energy batteries refer to batteries that use renewable, non-polluting and other non-traditional energy as energy. With the continuous growth of scientific research assets, various emerging new energy batteries have gradually come into the eyes of consumers and are widely used in various fields, bringing huge economic and environmental value.

[0003] As a source of power energy, new energy batteries have stable voltage, stable current, long-term stable power supply, and are little affected by the outside world. In addition, the battery structure is simple, easy to carry, and the charging and discharging operations are simple and easy.

[0004] In the field of new energy, new energy battery cells are key components, and their production and processing procedures are crucial. At present, some new energy battery cells are made of semiconductor crystal sheets, which are expensive. In the battery cell loading process, the traditional clamping loading method is gradually replaced by suction cup loading. With higher flexibility, suction cup loading can more conveniently handle battery cells of different sizes and shapes, and effectively reduce the risk of damage to the battery cells (scratched or damaged by traditional clamps, etc.), effectively ensuring the quality of the battery cells.

[0005] However, there are serious defects in the suction cup feeding. Usually, the suction cup is attached to the upper surface of the battery cell. When there is a sudden power outage or gas outage, the suction cup will lose its adsorption force, causing the battery cell in the feeding process to fall off the suction cup. This will damage the battery cell itself, increase production costs, interrupt the production process, and reduce production efficiency. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides a new energy battery cell feeding mechanism to solve the problems generated when feeding new energy battery cells.

[0008] (II) Technical solution

[0009] To achieve the above object, the present invention provides the following technical solutions: a new energy battery sheet feeding mechanism, comprising a lifting device and a connected mounting frame, the lifting device is used to drive the mounting frame to lift, a suction cup is installed on the mounting frame to absorb the battery sheet, a supporting frame is slidably installed on the mounting frame, and a supporting member is installed at the bottom of the supporting frame;

[0010] A connecting rod is hinged on the support frame, and a support rod is hinged on the other end of the connecting rod, and the support rod is fixed in position;

[0011] When the lifting device drives the mounting frame to descend, the suction cup and the supporting frame on the mounting frame descend together, and the distance between the supporting frame and the support rod increases, so that the inclination angle of the connecting rod changes, driving the supporting frame to slide, so that the supporting member moves away from the battery cell, and the suction cup descends to contact the surface of the battery cell and adsorbs the battery cell;

[0012] When the lifting device drives the mounting frame to rise, the battery cell adsorbed by the suction cup and the supporting bracket rise together, the distance between the supporting bracket and the support rod is reduced, and the supporting bracket is driven to slide through the reverse linkage of the connecting rod, so that the supporting member moves in the direction close to the battery cell and is located below the battery cell to prevent the battery cell from falling.

[0013] Furthermore, the upper surface of the supporting member is arranged in a plane, and the upper surface of the supporting member is parallel to the lower surface of the battery cell.

[0014] Furthermore, the position of the supporting member is adjustable to adjust the horizontal distance between the end of the supporting member facing the battery cell and the battery cell.

[0015] Furthermore, the support member is position-adjusted by rotating a lead screw installed at the bottom of the support frame.

[0016] Furthermore, a mounting piece is provided at the bottom of the mounting frame, and a slot is provided in the mounting piece. The interior of the slot is used to install a supporting piece, and an opening for the supporting piece to pass through is provided on the side of the slot facing the battery cell. The lead screw is rotatably connected to the mounting piece, and a screwing piece for rotating the lead screw is provided at the end of the lead screw.

[0017] Furthermore, a slide rail arranged along the movement direction of the supporting member is installed on the inner wall of the slot, and a slider is arranged on the supporting member, and the slider is slidably connected to the slide rail.

[0018] Furthermore, a scale is provided on the side wall of the mounting member, and an opening for observing the position of the supporting member is provided on the side of the slot.

[0019] Furthermore, a shell is installed on the side of the battery cell, and an air inlet cavity and a connecting cavity are arranged inside the shell. The air inlet cavity and the connecting cavity are connected through a through hole. An exhaust port connected to the air inlet cavity is opened on the shell, and an air inlet passing through the connecting cavity is opened on the shell. The exhaust port is located higher than the air inlet, and an air inlet pipe connected to the air inlet cavity is connected to the shell.

[0020] Furthermore, the height of the exhaust port is higher than the upper surface of the uppermost battery cell, and the gas discharged from the exhaust port is used to clean the surface of the battery cell. The position of the air inlet is aligned with the edge of the second upper battery cell to reduce the air pressure at the edge of the battery cell.

[0021] Furthermore, it also includes a support frame for stacking the battery cells, a base is provided at the bottom of the support frame, a feeding device for pushing the battery cells is provided on the base, and a sensor for detecting the top battery cell is provided on the support frame.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a new energy battery sheet feeding mechanism, which has the following features:

[0024] Beneficial effects:

[0025] The new energy battery cell feeding mechanism is provided with a support frame, a connecting rod, a support rod and a supporting member, a support frame sliding on the mounting frame, and uses the hinge relationship between the connecting rod and the fixed support rod. When the lifting device starts and drives the mounting frame to descend, during the process of adsorbing the battery cell, the support frame and the supporting member move away from the battery cell, ensuring that the suction cup will not be hindered during the adsorption operation, avoiding the battery cell, and can normally complete the adsorption work of the battery cell.

[0026] When the lifting device drives the mounting frame to rise and enters the battery cell loading process, as the mounting frame rises, the supporting frame moves the supporting parts at the bottom of the supporting frame to the bottom of the battery cell under the reverse linkage of the connecting rod and the support rod, and a stable protective structure is built under the battery cell. When the suction cup loses its adsorption force instantly during the loading process, the supporting parts under the battery cell will firmly hold the battery cell to prevent it from falling. The risk of battery cell damage due to falling is greatly reduced, which provides a guarantee for the continuity of production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0041] See also Figure 3-4And 7-8, a new energy battery cell feeding mechanism of the present invention is composed of a lifting device 2 and a mounting frame 1, which are connected to each other. The lifting device 2 is a lifting drive device that can accurately and smoothly drive the mounting frame 1 to perform lifting and lowering movements. A suction cup 8 is installed on the mounting frame 1. In the process of taking out the battery cell 10, the lifting device 2 drives the mounting frame 1 to descend, and the suction cup 8 approaches the battery cell 10 together. The suction cup 8 uses its adsorption capacity to steadily adsorb the battery cell 10, and then the lifting device 2 drives the mounting frame 1 to rise again to complete the operation of taking out the battery cell 10.

[0042] The lifting device 2 can be a variety of devices that can drive the installation frame 1 to rise and fall, such as a cylinder, an electric telescopic rod, a linear motor, etc.

[0043] Cylinder: The cost is relatively low and the budget can be effectively controlled. It has a very fast response speed and can complete the lifting action in a short time. It is suitable for scenes with high requirements for reaction time. In addition, the structure is relatively simple, and the subsequent maintenance is easy and convenient, which reduces the maintenance cost and time.

[0044] Electric telescopic pole: It is very easy to operate, and can achieve precise lifting and lowering through simple circuit control. The positioning accuracy is extremely high, which can meet the work with strict requirements on position accuracy. In addition, the operation process is stable and quiet, and will not generate too much noise interference.

[0045] Linear motor: With ultra-high speed and acceleration, it can quickly complete large-scale lifting and lowering, greatly improving work efficiency.

[0046] The suction cup 8 on the mounting frame 1 is a key component for realizing the material adsorption and handling function, and the suction cup 8 is connected to the air pipe 9. Through the suction operation of the suction cup 8 on the battery cell 10, the staff can select a vacuum suction cup or a Bernoulli disc according to the actual use situation.

[0047] The working principle of the vacuum suction cup is that when the adsorption process is started, the external gas source equipment (such as a vacuum pump) suctions the inside of the suction cup 8 through the gas pipe 9. As the gas is continuously extracted, the air pressure inside the suction cup 8 drops rapidly, forming a negative pressure environment. Under the action of the external atmospheric pressure, the battery cell 10 is pressed tightly against the suction cup 8, thereby achieving firm adsorption. This adsorption method based on negative pressure difference allows the vacuum suction cup 8 to work stably on the flat and smooth surface of the battery cell 10, ensuring that the battery cell 10 will not fall off easily during transportation.

[0048] Applicable scenarios: Suitable for cells with relatively flat surfaces and no air permeability, such as common semiconductors and crystalline silicon cells. In the production line of the cell 10, the vacuum suction cup 8 can play an efficient role in the material transfer process from the loading process to the installation process.

[0049] The working principle of the Bernoulli suction cup is that the gas pipe 9 is responsible for inputting the gas into the Bernoulli suction cup. When the gas enters, it will be accelerated in the specially designed cavity structure, and then ejected from the specific nozzle of the suction cup at high speed. According to the Bernoulli principle, the greater the fluid flow rate, the smaller its static pressure. When high-speed gas is ejected from the Bernoulli suction cup 8, a low-pressure area relative to the surrounding environment is formed in the area near the nozzle of the suction cup 8. At this time, the other side of the adsorbed object is under normal atmospheric pressure. Under the action of the pressure difference caused by the high-speed airflow, the external atmospheric pressure will press the object tightly against the Bernoulli suction cup 8, thereby achieving stable adsorption of the object. This process can complete the adsorption operation without direct contact with the surface of the object, and is particularly suitable for the transportation of objects that are sensitive to surface damage, fragile in texture or uneven in surface.

[0050] Applicable scenarios: For some battery cells 10 with textures or fragile coatings, the Bernoulli suction cup 8 can achieve adsorption without contacting the surface of the battery cell 10, avoiding scratches or other damages to the battery cell 10.

[0051] When multiple suction cups 8 are installed on the mounting frame 1, in order to ensure that each suction cup 8 can work stably, a branch joint 20 is used to connect the gas pipe 9 and the suction cup 8. The branch joint 20 can evenly distribute the air flow of the gas pipe 9 to each branch, ensuring that each suction cup 8 obtains sufficient and stable gas supply or air extraction effect.

[0052] The support bracket 3 is slidably mounted on the mounting frame 1. A linear guide 31 is mounted on the side of the support bracket 3. A connecting block 32 matching the linear guide 31 is mounted on the mounting frame 1. The connecting block 32 has a built-in high-precision ball bearing, so that the support bracket 3 can slide smoothly horizontally on the mounting frame 1. The sliding connection between the support bracket 3 and the mounting frame 1 can also be achieved in other ways. A supporting member 7 is installed at the bottom of the support bracket 3. The supporting member 7 can be block-shaped, columnar, sheet-shaped, etc. The supporting member 7 of any shape and structure can be used in the supporting member 7 of the present invention. However, the supporting member 7 preferably uses a supporting member 7 with a flat upper surface, and the upper surface of the supporting member 7 is parallel to the lower surface of the battery cell 10, so that the support member 7 and the battery cell 10 are more stable. The outside of the supporting member 7 is wrapped with an elastic rubber material, which can provide stable support force and good friction, and avoid scratching the surface of the battery cell 10.

[0053] The movement of the support frame 3 is driven by the linkage of the connecting rod 6. One end of the connecting rod 6 is hinged to the support frame 3 through the connecting shaft 18. The specific implementation scheme of this hinge method is to open a pin hole adapted to the connecting shaft 18 on the support frame 3. After the connecting shaft 18 is inserted into the pin hole, an elastic retaining ring or a split pin is used for axial positioning to ensure that the connecting shaft 18 will not fall out, so as to achieve a relatively rotatable connection between the two. In addition to the connection with the connecting shaft 18, the hinge method commonly used in industry can also be used for hinge connection, such as using a hinge for connection, fixing one side of the hinge to the support frame 3 by bolts, and connecting the other side to the connecting rod 6, which can also achieve a hinge effect, and the hinge can withstand a certain lateral force to make the connection more stable.

[0054] The other end of the connecting rod 6 is hinged to the support rod 5 through the connecting shaft 2 19, and its installation method is the same as the hinge of the connecting rod 6 and the support bracket 3. In order to ensure that the position of the support rod 5 remains unchanged, a fixing member 4 is provided on the support rod 5. The fixing member 4 can be fixedly connected with different devices according to the actual application scenario. For example, in a stable support structure, the fixing member 4 can be designed as a block or a hoop form, and the fixing member 4 is tightly fixed to the crossbeam or column of the support by bolts or welding, so that the support rod 5 is stable. When using a cylinder (the same applies to the telescopic rod), the fixing member 4 is installed on the outer wall of the cylinder, such as by welding or using bolts to fix the fixing member 4 to the outer wall of the cylinder, so that the support rod 5 remains stationary during the operation of the cylinder. The mounting frame 1 is installed at the telescopic end of the cylinder. When the cylinder performs a telescopic action, the mounting frame 1 moves accordingly, and through the linkage action of the connecting rod 6, the support bracket 3 is driven to slide according to a predetermined trajectory.

[0055] like Figure 7 As shown, the descending adsorption process: when the lifting device 2 is started and the mounting frame 1 is driven to descend, the suction cup 8 on the mounting frame 1 and the support bracket 3 descend synchronously. As the support bracket 3 descends, the distance between the support bracket 3 and the fixed support rod 5 gradually increases, which causes the inclination angle of the connecting rod 6 to change. According to the motion characteristics of the connecting rod 6 mechanism, the change in the angle of the connecting rod 6 will drive the support bracket 3 to slide along the linear guide rail 31, and then move the supporting member 7 away from the battery cell 10, avoiding the battery cell 10, so as to avoid interference with the adsorption action during the descent of the suction cup 8. When the suction cup 8 descends to contact the surface of the battery cell 10, the suction cup 8 adsorbs the battery cell 10.

[0056] like Figure 8As shown, the ascending and transporting process: when the lifting device 2 drives the mounting frame 1 to ascend, the suction cup 8 that has adsorbed the battery cell 10 rises together with the support frame 3. During the ascending process, the distance between the support frame 3 and the support rod 5 gradually decreases, and the connecting rod 6 moves in the opposite direction. This reverse movement will link the support frame 3 to slide in the opposite direction along the linear guide rail 31 again, so that the support member 7 moves in the direction close to the battery cell 10 until the support member 7 moves to the bottom of the battery cell 10. At this time, the support member 7 is placed under the battery cell 10 to build a stable protective structure for the battery cell 10. When the suction cup 8 loses its adsorption force instantly during the loading process, the support member 7 located under the battery cell 10 will firmly hold the battery cell 10. It effectively prevents the battery cell 10 from falling due to unexpected circumstances during the transportation process, ensures the safety of the battery cell 10, and effectively prevents economic losses caused by damage to the battery cell 10.

[0057] There is a certain distance between the supporting member 7 and the battery cell 10 adsorbed by the suction cup 8. The suction cup 8 can independently complete the adsorption and transportation movement of the battery cell 10. During the entire normal adsorption and movement process, the supporting member 7 does not need to contact the battery cell 10, which effectively avoids the wear of the battery cell 10 caused by the friction between the supporting member 7 and the lower surface of the battery cell 10 during movement, thereby ensuring the integrity of the surface of the battery cell 10. The supporting member 7 will only play its important role when there is a risk of accidental falling of the battery cell 10. At this time, the supporting member 7 supports the battery cell 10 to prevent the battery cell 10 from continuing to fall, providing protection for the transportation process of the battery cell 10.

[0058] The supporting member 7 plays an important protective role in the process of loading the battery cell 10, and its position can be fixedly installed at the bottom of the supporting frame 3 or can be adjustably installed at the bottom of the supporting frame 3. The fixed installation method has a simple structure and low cost; the adjustable installation method can adapt to various operation requirements.

[0059] The position of the supporting member 7 can be adjusted to adjust the horizontal distance between the end of the supporting member 7 facing the battery cell 10 and the battery cell. The following connection methods can be used:

[0060] 1. The supporting member 7 is slidably connected to the supporting frame 3 , and there is a certain damping force between the two. By manually sliding the supporting member 7 , the distance between the supporting member 7 and the battery cell 10 can be easily adjusted.

[0061] 2. Bolt connection can also be adopted, a row of evenly spaced mounting holes are opened on the support frame 3, and the support member 7 is fastened by bolts through the support frame 3. When the bolts are loosened, the support member 7 can be disassembled, and after adjusting to the mounting holes at appropriate positions, the bolts are tightened to fix the support member 7.

[0062] 3. If Figure 5-9As shown, a mounting member 11 can also be installed at the bottom of the mounting frame 1. A slot 14 is provided inside the mounting member 11. The slot 14 is used to accommodate the supporting member 7. An opening is provided on the side of the slot 14 facing the battery cell 10 for the supporting member 7 to pass through. The lead screw 12 is connected to the mounting member 11 by a bearing (or a shaft hole). The end of the lead screw 12 is equipped with a screw 17. The operator can easily rotate the lead screw 12 by rotating the screw 17. The screw 17 is provided with a notch, which can be screwed with a tool. On the inner wall of the slot 14, a slide rail 15 arranged along the movement direction of the supporting member 7 is installed. A slider 13 is provided on the supporting member 7. The slider 13 is slidably connected to the slide rail 15, which ensures the stability and accuracy of the movement of the supporting member 7. In addition, an opening is also provided on the side of the slot 14, which is convenient for the operator to directly observe the position of the supporting member 7, so as to better grasp the adjustment position of the supporting member 7. By rotating the lead screw 12, the position of the supporting member 7 can be accurately adjusted. This adjustment method is relatively simple to operate and has significant stability.

[0063] The side wall of the mounting member 11 is provided with a scale 16, and the operator can directly refer to the scale 16 on the side wall of the mounting member 11 when adjusting the position of the supporting member 7. By observing the relative position of the supporting member 7 and the scale 16, the supporting member 7 can be accurately adjusted.

[0064] The purpose of the adjustable position of the supporting member 7 is to directly adjust the response speed of the supporting member 7, that is, the relationship between the movement of the supporting member 7 to the bottom of the battery cell 10 and the lifting height of the supporting frame 3. When the supporting member 7 is far away from the battery cell 10, the mounting frame 1 needs to rise a higher distance so that the supporting member 7 can move to the bottom of the battery cell 10 for protection. When the supporting member 7 is brought close to the battery cell 10, the lifting device 2 drives the mounting frame 1 to rise a shorter distance, and the supporting member 7 can quickly reach the bottom of the battery cell 10 to play a protective role. In actual use, the operator can flexibly adjust the distance between the supporting member 7 and the battery cell 10 according to the actual operating conditions of the battery cell 10, so as to achieve precise adjustment of the response speed of the supporting member 7. For example: during the loading process of the battery cell 10, the suction cup 8 absorbs the battery cell 10 and causes it to rise. When there is a safe distance between the battery cell 10 and the placement device or the battery cell 10 below, even if the battery cell 10 accidentally falls, it will fall on the placement device or the battery cell 10 below. At this time, there is no need for the support member 7 to intervene in protection too early, and the operator can adjust the support member 7 to a position farther away from the battery cell 10. On the contrary, if the support member 7 is expected to protect the battery cell 10 more quickly, the support member 7 can be adjusted to a position close to the battery cell 10 according to actual needs, so as to flexibly adapt to different usage scenarios.

[0065] In addition, by setting the position adjustment of the supporting member 7, in certain specific operating scenarios, if it is determined that the supporting member 7 is not needed, the operator can adjust the supporting member 7 to a position farther away from the battery cell 10, so that the supporting member 7 is completely not involved in the process of removing the battery cell 10.

[0066] like Figure 3 As shown, a support frame 28 for stacking battery cells 10 is installed below the suction cup 8. The support frame 28 has good load-bearing capacity and can safely and stably stack multiple battery cells 10. A base 29 is provided at the bottom of the support frame 28, which is tightly fixed to the support frame 28 by anchor bolts, anti-slip pads, corner pieces, etc., providing a solid and reliable support foundation for the stacking of the battery cells 10.

[0067] A feeding device 33 is provided on the base 29 to push the battery cell 10. The feeding device 33 can be a device with a feeding function such as a cylinder and an electric telescopic rod. Taking the cylinder feeding device 33 as an example, when the device is started, compressed air enters the cylinder, pushing the piston to make reciprocating linear motion, thereby generating thrust to accurately push the battery cell 10 to the predetermined position. If an electric telescopic rod is used, the motor is powered on and runs, driving the screw nut mechanism to work, converting the rotational motion of the motor into linear motion, and pushing the battery cell 10 to move.

[0068] A sensor 30 for detecting the topmost battery cell 10 is installed above the support frame 28. The sensor 30 is electrically connected to the feeding device 33 through a signal line to form an automated control closed loop. When the topmost battery cell 10 rises to the position that triggers the sensor 30, the sensor 30 will immediately transmit a signal to the feeding device 33. After receiving the signal, the feeding device 33 responds quickly and automatically stops feeding. In this way, the topmost battery cell 10 among the stacked battery cells 10 is always maintained at a fixed height. This creates favorable conditions for the subsequent lifting device 2 to drive the suction cup 8 on the mounting frame 1 to descend and retrieve materials, provides a fixed and stable loading environment, effectively improves the accuracy and efficiency of the suction cup 8 retrieving materials, ensures the smooth progress of the entire battery cell 10 handling process, and greatly improves the automation level and production efficiency of the equipment.

[0069] like Figure 1-2 As shown, the new energy battery cell 10 is usually installed on a carrier 36 for carrying batteries, such as a battery module, a battery pack or a carrier frame. The carrier 36 also has an installation groove 37 for installing the battery cell 10. The size of the installation groove 37 is precisely matched with the battery cell 10, and the battery cell 10 can be firmly fixed when installed inside it.

[0070] In order to meet the needs of automated production, a conveying device 35 for conveying the carrier 36 is installed near the lifting device 2. The conveying device 35 can use a conveyor belt or a conveyor table commonly used in daily industrial production. The conveyor belt drives the rollers through a motor, and relies on friction to drive the carrier 36 to move smoothly; the conveyor table uses a motor in conjunction with a screw nut, a gear rack and other transmission structures to realize the conveying of the carrier 36, ensuring that the carrier 36 can be accurately and efficiently transported to the designated position to wait for the installation of the battery cell 10. Support legs 40 are set at the bottom of the conveying device 35. The support legs 40 are designed with adjustable height, and the height can be flexibly adjusted through common threaded lifting structures to meet the needs of carriers 36 of different heights.

[0071] In order to drive the cell 10 that has been successfully taken to move, a displacement drive device 34 is connected to the lifting device 2. The displacement drive device 34 has various types, and can be a mechanical arm, a linear motor, or a slide, such as a ball screw slide, or a cylinder slide, to move the cell 10 to a specified position.

[0072] When the displacement drive device 34 uses a linear motor or a slide, a fixing frame 39 is installed at the bottom of the displacement drive device 34 to ensure its stable operation. It can provide stable support for the linear motor or the slide. In order to accurately determine the movement position of the displacement drive device 34, a travel switch 38 is set at both ends. The travel switch 38 is connected to the control system through a precise mechanical structure and an electrical circuit. When the displacement drive device 34 runs to the end point of the stroke, the corresponding travel switch 38 will be triggered. The travel switch 38 immediately sends a signal to the control system. After receiving the signal, the control system accurately controls the displacement drive device 34 according to the preset program, such as adjusting the speed, stopping the operation or changing the running direction.

[0073] When the suction cup 8 successfully absorbs the battery cell 10 and rises to the position with the lifting device 2, the displacement drive device 34 is immediately started to accurately drive the battery cell 10 to move above the carrier 36 where the battery cell 10 is placed. At this time, the lifting device 2 begins to descend and slowly places the battery cell 10 in the installation groove 37 of the carrier 36. In this process, when the lifting device 2 is started and the mounting frame 1 is driven to descend, the supporting member 7 is moved away from the battery cell 10 through the linkage method described in detail above, avoiding the battery cell 10, ensuring that there is no obstacle to the battery cell 10 descending and being installed on the carrier 36, thereby successfully completing a series of actions of the battery cell 10 from adsorption to installation on the carrier 36.

[0074] like Figure 3 As shown, a shell 21 is installed on the side of the battery cell 10. The shell 21 can be fixedly connected to the support frame 28, or a supporting device such as a rod, a supporting plate, etc. can be provided to support the shell 21. Figure 10-12As shown, the interior of the housing 21 is divided into an air inlet chamber 22 and a connecting chamber 24, and the connecting chamber 24 is connected to the through hole 26 of the air inlet chamber 22. The housing 21 is provided with an exhaust port 23 and an air inlet 25, the exhaust port 23 is connected to the air inlet chamber 22, and the air inlet 25 is connected to the connecting chamber 24, and the exhaust port 23 is located higher than the air inlet 25. The air inlet pipe 27 installed on the housing 21 is connected to the air inlet chamber 22, and is used to transport gas into the air inlet chamber 22.

[0075] When installing the housing 21, the height of the exhaust port 23 is higher than the upper surface of the uppermost battery cell 10, and the air inlet pipe 27 starts to deliver gas into the air inlet cavity 22. At this time, a large amount of gas is discharged from the exhaust port 23 connected to the air inlet cavity 22, and the surface of the battery cell 10 is cleaned by blowing, effectively removing dust, debris and other tiny impurities that may exist on the surface of the battery cell 10, and ensuring the cleanliness of the battery cell 10 in the subsequent processing process.

[0076] like Fig.12 As shown, at the same time, since the connecting cavity 24 is connected to the air inlet cavity 22 through the through hole 26, according to the Bernoulli principle, when the gas in the air inlet cavity 22 flows rapidly, the pressure in the connecting cavity 24 will decrease accordingly. The existence of the pressure difference allows the external gas to quickly enter the connecting cavity 24 from the air inlet 25, thereby causing the pressure near the air inlet 25 to decrease. The position of the air inlet 25 is precisely aligned with the edge of the second upper battery cell 10, which reduces the air pressure at the edge of the second upper battery cell 10 and forms a horizontal force at the edge of the battery cell 10.

[0077] In the traditional process of taking out the battery cell 10, due to the air tension between the top battery cell 10 and the lower battery cell 10, when the top battery cell 10 is taken out, the battery cell 10 below it can be easily lifted to a certain height. Once the lower battery cell 10 falls after being lifted, it is very easy to cause damage. The invention adopts a unique gas control method, and there is no need to use traditional contact methods such as clamping. By reducing the air pressure near the air inlet 25, the edge of the second upper battery cell 10 is subjected to a horizontal force, which can effectively balance the upward force generated by the air tension, so that when the top battery cell 10 is adsorbed, the lower battery cell 10 will not be lifted. In addition, this non-contact processing method avoids direct contact with the battery cell 10, eliminates possible scratches on the battery cell 10 due to contact, greatly improves the safety and stability of the battery cell 10 taking process, and effectively improves product quality.

[0078] In addition, the shell 21 can be installed on multiple sides of the battery cell 10. The multi-sided arrangement can achieve all-round surface cleaning of the battery cell 10, ensuring that dust and impurities in all directions can be effectively blown away, greatly improving the comprehensiveness and thoroughness of cleaning, and providing a cleaner surface environment for subsequent processing of the battery cell 10. The air inlets 25 on multiple sides can form pressure differences at more edges of the battery cell 10, more stably balance the air tension between the battery cells 10, and effectively prevent the lower battery cell 10 from being lifted up when taking materials, significantly improving the safety and stability of taking materials, effectively reducing the damage rate of the battery cell 10 during transportation, and improving the overall product quality of the battery cell 10 and the cleanliness of installation.

[0079] The exhaust work at the exhaust port 23 of the shell 21 does not work continuously and uninterruptedly. It can cooperate with the lifting device 2 to achieve precise air supply control with the help of sensors, solenoid valves and other components, so as to improve energy utilization efficiency and optimize the overall work process.

[0080] Specifically, when the lifting device 2 moves to the top of the battery cell 10 to prepare for material collection, its descending action will trigger a series of automated control processes. At this time, the sensor installed on the lifting device 2 will capture this change in action and transmit the signal to the control system associated with it. The control system then sends a command to the solenoid valve to control the solenoid valve to open, so that the air intake pipe 27 starts to supply air to the air intake cavity 22 in the shell 21. A large amount of gas is discharged through the exhaust port 23 connected to the air intake cavity 22, cleaning the surface of the battery cell 10 and providing a clean working environment for subsequent material collection operations.

[0081] When the lifting device 2 finishes taking materials and starts to rise and moves to a certain position, the sensor comes into play again. The sensor detects the position change of the lifting device 2 and feeds back the signal to the control system. The control system sends a command to the solenoid valve according to the preset program, controls the solenoid valve to close, thereby stopping the air supply to the air inlet pipe 27, and the exhaust port 23 also stops exhausting.

[0082] This air supply control method based on the action of the lifting device 2, in conjunction with the sensor and the solenoid valve, avoids meaningless continuous exhaust of the exhaust port 23, and only performs effective cleaning work at the critical stage of taking materials from the battery cell 10, which not only saves energy consumption but also extends the service life of related equipment. The exhaust port 23 will only work again when the lifting device 2 moves to the top of the battery cell 10 again to prepare for taking materials and repeats the above action process.

[0083] In summary, when the new energy battery cell feeding mechanism is used:

[0084] 1. Material collection stage

[0085] The lifting device 2 begins to descend. During the descending process, the supporting member 7 moves away from the battery cell 10 through the mutual force between the support rod 5, the connecting rod 6 and the supporting bracket 3, thereby avoiding collision and interference between the supporting member 7 and the battery cell 10.

[0086] When the suction cup 8 is lowered to the position of the battery cell 10 along with the lifting device 2 , the suction cup 8 is activated to absorb the battery cell 10 .

[0087] After the suction cup 8 absorbs the battery cell 10, the lifting device 2 drives in the reverse direction, driving the mounting frame 1 to rise and lift the battery cell 10. At this time, the supporting member 7 is moved to the bottom of the battery cell 10 by the force, playing a protective role to prevent the battery cell 10 from accidentally falling and causing damage. In the process of taking out the battery cell 10, the shell 21 located on the side of the battery cell 10 starts to work, and the exhaust port 23 discharges gas to clean the surface of the battery cell 10 to remove dust, impurities, etc.; the air inlet 25 forms a negative pressure, and according to the Bernoulli principle, the air pressure at the edge of the second upper battery cell 10 is reduced to prevent the second upper battery cell 10 from rising together with the upper battery cell 10 due to air tension, thereby avoiding the second upper battery cell 10 from breaking.

[0088] 2. Transportation and installation stage

[0089] When the battery cell 10 is raised to a certain height along with the lifting device 2 , the displacement driving device 34 is started to accurately drive the suction cup 8 adsorbing the battery cell 10 to above the carrier 36 for placing the battery cell 10 .

[0090] After reaching the top of the carrier 36, the lifting device 2 descends again to install the battery cell 10 on the carrier 36. During the descent process, the supporting member 7 is away from the battery cell 10 to prevent obstruction to the installation of the battery cell 10 and ensure that the battery cell 10 can be smoothly installed in the installation groove 37 of the carrier 36.

[0091] 3. Feeding and replenishment stage

[0092] When the topmost cell 10 is taken away, the sensor 30 is not triggered, and the control feeding device 33 starts working. The feeding device 33 (such as a cylinder, an electric telescopic rod, etc.) pushes the cell 10 upward, so that the cell 10 above the next cell rises to the top, until it reaches the detection position of the sensor 30 at the top of the support frame 28. After the sensor 30 detects that the cell 10 is in place, it will automatically control the feeding device 33 to stop feeding, and prepare for the next cell 10 to be taken, and the continuous transportation and installation of the cell 10 is completed in this cycle.
