Description

Technical Field

[0001] This utility model relates to the field of lithium battery surface cleaning technology, specifically to a surface cleaning device for square-shell lithium batteries. Background Technology

[0002] Square-shell lithium batteries, also known as rectangular lithium batteries, are one type of lithium battery and a common shape. They typically have an aluminum casing and contain multiple battery modules inside.

[0003] The accumulation of dirt and dust on the surface of lithium batteries can reduce their heat dissipation performance and affect their charging and discharging efficiency. If not cleaned for a long time, the chemical substances inside the lithium battery may leak out, posing a potential health hazard.

[0004] Existing reference CN202221839919.6 describes a lithium battery surface cleaning device that can perform five sets of surface cleaning: sides, large surfaces, and bottom surfaces. However, it still has the following problems: 1) After cleaning, the upright lithium batteries are easily tipped over during transport. Minor falls are usually not a problem, but severe falls may cause internal short circuits, leakage, or bulging, posing a safety hazard. Immediate shutdown and professional inspection are required, but continuous inspection is difficult to achieve in continuous production. Therefore, it is necessary to change the lithium battery placement from upright to horizontal.

[0005] 2) When the robotic arm grips the lithium battery, the descent height is basically the set distance. Existing robotic arms lack limit protection measures during descent to ensure that the compression does not damage the surface structure of the lithium battery.

[0006] To address these issues, we provide a surface cleaning device for prismatic lithium batteries. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a surface cleaning device for prismatic lithium batteries.

[0018] A guide post is installed inside the guide cylinder, with one end of the guide post being constrained to slide within the guide cylinder; the other end of the guide post is connected to the connecting plate.

[0019] A compression spring is installed between the connecting plate and the fixing plate, and the compression spring is sleeved on the outside of the guide post.

[0020] In a further technical solution, an anti-collision sensor is also installed between the connecting plate and the fixing plate, and the anti-collision sensor is used to detect the vertical distance between the connecting plate and the fixing plate;

[0021] The pneumatic gripper is detachably equipped with a product detection sensor for sensing lithium batteries.

[0022] In a further technical solution, the bottom cleaning mechanism includes an upward-opening housing and a bottom frame, with a brush cylinder installed inside the housing; the housing is fixedly installed on the bottom frame.

[0023] A speed-regulating motor is installed on one side of the bottom frame, and the output end of the speed-regulating motor is coaxially connected to the brush cylinder. The speed-regulating motor drives the brush cylinder to rotate. An ion air knife is installed on one side of the bottom frame, and the lithium battery moves from the top of the ion air knife to the top of the brush cylinder. A dust collection trough is installed at the bottom of the bottom frame, and the top of the dust collection trough is connected to the casing.

[0024] In a further technical solution, the side cleaning mechanism includes a cleaning frame and two sets of symmetrically distributed brush cylinders, with the lithium battery passing between the two sets of brush cylinders.

[0025] Two sets of opposing side openings are installed on the cleaning rack; two sets of brush cylinders are installed in the side openings respectively, and the two sets of brush cylinders are set vertically.

[0026] A speed-regulating motor is coaxially connected to the bottom of the brush cylinder, and an ion air knife is provided on the side of the cleaning frame facing the bottom frame; dust collection troughs are installed on both sides of the cleaning frame.

[0027] In a further technical solution, the large-area cleaning mechanism includes a support frame, on which two sets of support plates are fixed, and on which a speed-regulating motor is installed;

[0028] A fixed opening shell is installed inside the support frame, a brush cylinder three is installed inside the fixed opening shell, and a dust collection trough three is installed at the opposite end; two sets of fixed opening shells are provided, with openings facing each other and used to pass through lithium batteries.

[0030] In a further technical solution, the rotating component includes a servo motor and a bending plate, with the output end of the servo motor coaxially connected to the reducer; a synchronous positioning frame is installed on the outside of the lifting component two, and a position plate one and a positioning plate are detachably installed on the bottom of the synchronous positioning frame.

[0031] The output end of the reducer passes through the position plate and the bending plate and is connected to the positioning plate;

[0032] The bending plate and the output end of the reducer are fixedly connected, and a gap is provided between the position plate and the bending plate; a pneumatic gripper is installed at the bottom of the bending plate, and a product detection sensor is installed on the gripper body at the bottom of the pneumatic gripper.

[0033] This invention meets the requirements of integrating the mechanisms of the prior art into a single machine. It also meets the automation requirements for cleaning the surface of prismatic lithium batteries. A side-mounted robotic arm on the side transfer mechanism grasps the battery and moves it sequentially from the bottom cleaning mechanism to the side cleaning mechanism. The rotating brush cylinders on the bottom and side cleaning mechanisms contact the lithium battery surface to clean surface contaminants. A large-area transfer mechanism grasps the lithium battery and moves it from the large-area cleaning mechanism, where the rotating brush cylinders on the side cleaning mechanism contact the battery surface to clean surface contaminants. A posture-conversion transfer mechanism changes the lithium battery from a vertical to a horizontal position. In this application, the prismatic lithium battery is cuboid in shape and has a connector at the top, thus eliminating the need for cleaning. The cuboid shape of the lithium battery results in one bottom surface, two large surfaces, and two sets of side surfaces, where the large surfaces are larger than the side surfaces. The two sets of side surfaces are symmetrically distributed, and the two sets of large surfaces are symmetrically distributed.

[0034] Compared with existing technologies, it has the following advantages:

[0035] In this application, on the one hand, the bottom cleaning mechanism, the side cleaning mechanism, and the large surface cleaning mechanism are used to thoroughly clean the prismatic lithium battery except for the top, so as to achieve a comprehensive cleaning effect; the lithium battery moving method can achieve the effect of quickly cleaning the battery surface; on the other hand, the posture conversion and transfer mechanism can be set up to move the prismatic lithium battery from a vertical position to a horizontal position by the large surface robot arm, so as to ensure the continuous transportation of the lithium battery.

[0036] Secondly, this application employs a dual-line production process, which allows for the surface cleaning of two sets of lithium batteries in a single operation, achieving a more efficient technical effect.

[0037] This invention utilizes a compression spring to ensure that the fixed plate presses down on the lithium battery as the lifting assembly descends. With continued downward pressure, the compression spring contracts, reducing the distance between the connecting plate and the fixed plate, thus providing a buffering effect. At this point, the detection end of the anti-collision sensor is blocked, generating a signal change that is transmitted to the pneumatic circuit controller for feedback control, preventing the lifting assembly from continuing to descend.

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] Example 1

[0057] like Figure 1-5 As shown, this is one embodiment of the present invention, specifically a surface cleaning device for a square-shell lithium battery. A set of side transfer mechanisms 1 and a set of posture conversion transfer mechanisms 6 are installed on the workbench of the device. Two sets of large-area transfer mechanisms 4 are installed at the bottom of the side transfer mechanisms.

[0058] The transfer mechanisms are all used for transporting and turning prismatic lithium batteries;

[0059] Initially, two sets of prismatic lithium batteries are transported and placed in the middle of the side transfer mechanism.

[0060] like Figure 2 As shown, the side transfer mechanism 1 includes a frame 12, on which a side robot arm 11 is mounted for clamping lithium batteries 100; two sets of side robots arm are provided, and the side robots arm 11 drive the two sets of lithium batteries 100 from the middle to both sides in sequence through the bottom cleaning mechanism 2 and the side cleaning mechanism 3, and place them on the large surface transfer mechanism 4; the side transfer mechanism 1 includes a top guide rail 13, on which a lifting assembly 14 is mounted, and the side robot arm 11 is mounted at the bottom of the lifting assembly 14;

[0061] like Figure 3 As shown, the side-mounted robotic arm 11 includes a gripper 111, with a fixed plate 112 and a connecting plate 113 mounted on its top. The bottom of the fixed plate 112 is fixedly connected to the gripper 111, and guide cylinders 114 are mounted on both ends of the bottom. The connecting plate 113 is connected to the lifting assembly 14. The guide cylinder and the guide post are in a telescopic relationship. The guide cylinder is fixed to the connecting plate, and the guide post passes through the connecting plate and is constrained within the guide cylinder. The constraint can be achieved by an inner groove inside the guide cylinder, and the end of the guide post can be a ball head that is installed in the inner groove through thermal expansion and contraction and is constrained so as not to detach. By setting a compression spring, the fixed plate presses down on the lithium battery when the lifting assembly 1 descends. With continuous downward pressure, the compression spring contracts, and the distance between the connecting plate and the fixed plate decreases, providing a buffering effect. At this time, the detection end of the anti-collision sensor is blocked, thereby generating a signal change, which is transmitted to the pneumatic circuit controller for feedback control to prevent the lifting assembly 1 from descending continuously.

[0062] A guide post is installed inside the guide cylinder 114. One end of the guide post is constrained and slides within the guide cylinder 114; the other end of the guide post is connected to the connecting plate 113.

[0063] A compression spring 115 is installed between the connecting plate 113 and the fixing plate 112, and the compression spring 115 is sleeved on the outside of the guide post.

[0064] like Figure 3 As shown, an anti-collision sensor 116 is also installed between the connecting plate 113 and the fixing plate 112. The anti-collision sensor 116 is used to detect the vertical distance between the connecting plate 113 and the fixing plate 112. The anti-collision sensor can be a non-contact sensor, such as... Figure 3 As shown, the lower post is inserted into the upper position to generate a signal transmission by changing the infrared or magnetic induction.

[0065] The pneumatic gripper 111 is detachably equipped with a product detection sensor 117 for sensing the lithium battery 100. An air tube is connected to the upper part of the gripper, which is then driven... Figure 3 The grippers at the bottom move inward or outward to achieve clamping and releasing effects. A slot is cut into one set of grippers and a product detection sensor is installed to detect whether an object is located inside the gripper.

[0066] Bottom cleaning mechanism 2 cleans the bottom surface of lithium battery 100 from the bottom; side cleaning mechanism 3 cleans the sides of lithium battery 100 from both sides; in this embodiment, the bottom cleaning mechanism and side cleaning mechanism can be cleaning components such as brushes and felts for surface contact cleaning. If appropriate, cleaning fluid can be added.

[0067] like Figure 4 As shown, the large-area transfer mechanism 4 includes a frame 41 and a large-area track 42. A large-area robot 43 is laterally slidably connected to the frame 41. The large-area robot 43 drives the lithium battery 100 to move along the direction of the large-area track and pass through the large-area cleaning mechanism 5. The bottom of the frame 41 is fixed to the workbench, and the large-area track is installed laterally for the large-area robot to slide. The large-area robot is clamped upward on the cleaned side of the lithium battery. A bearing platform is provided on the large-area robot for placing the lithium battery.

[0068] like Figure 5 As shown, the large-area cleaning mechanism 5 includes symmetrically distributed brush cylinders 51. The lithium battery 100 passes between two sets of brush cylinders 51, and the brush cylinders 51 clean the large surface of the lithium battery 100.

[0069] The large-area cleaning mechanism 5 includes a support frame 52, the bottom of which is detachably mounted on a workbench. Two sets of support plates 53 are fixed on the support frame 52, and a speed-regulating motor 55 is mounted on the support plate 53.

[0070] A fixed opening shell is installed inside the support frame 52, and a brush cylinder 3 51 is installed inside the fixed opening shell. A dust collection trough 3 54 is installed opposite to it. Two sets of fixed opening shells are provided, with openings facing each other for the passage of lithium battery 100. An ion air knife 3 56 is fixedly installed on the outside of the support frame.

[0071] The attitude conversion and transfer mechanism 6 is used to grasp the lithium battery 100 and change the large surface of the lithium battery 100 from vertical to horizontal.

[0072] In this application, on the one hand, the bottom cleaning mechanism, the side cleaning mechanism, and the large surface cleaning mechanism are used to thoroughly clean the prismatic lithium battery except for the top, so as to achieve a comprehensive cleaning effect; the lithium battery moving method can achieve the effect of quickly cleaning the battery surface; on the other hand, the posture conversion and transfer mechanism can be set up to move the prismatic lithium battery from a vertical position to a horizontal position by the large surface robot arm, so as to ensure the continuous transportation of the lithium battery.

[0073] Secondly, this application employs a dual-line production process, which allows for the surface cleaning of two sets of lithium batteries in a single operation, achieving a more efficient technical effect.

[0074] Example 2

[0075] like Figure 6-9 As shown, this is another embodiment of the present invention, based on embodiment 1, as follows: Figure 6 As shown, the bottom cleaning mechanism 2 includes an upward-opening housing 21 and a bottom frame 23. A brush cylinder 22 is installed inside the housing 21; the housing 21 is fixedly installed on the bottom frame 23.

[0076] A speed-regulating motor 24 is installed on one side of the bottom frame 23, and the output end of the speed-regulating motor 24 is coaxially connected to the brush cylinder 22; the speed-regulating motor 24 drives the brush cylinder 22 to rotate; an ion air knife 25 is installed on one side of the bottom frame 23, and the lithium battery 100 moves from the top of the ion air knife 25 to the top of the brush cylinder 22; a dust collection trough 26 is installed at the bottom of the bottom frame 23, and the top of the dust collection trough 26 is connected to the housing 21. A lateral sub-frame is installed between the speed-regulating motor and the bottom frame, and the lateral sub-frame is used to fix the speed-regulating motor. The output end of the speed-regulating motor passes through the lateral sub-frame and is connected through a coupling, and is coaxially connected to the brush cylinder. The top height of the brush cylinder should be higher than the height of the bottom frame to facilitate bottom cleaning.

[0077] like Figure 7 As shown, the side cleaning mechanism 3 includes a cleaning frame 32 and two sets of symmetrically distributed brush cylinders 31, with the lithium battery 100 passing between the two sets of brush cylinders 31.

[0078] Two sets of opposing side openings are installed on the cleaning rack 32; two sets of brush cylinders 31 are respectively installed in the side openings, and the two sets of brush cylinders 31 are set vertically.

[0079] A speed-regulating motor 33 is coaxially connected to the bottom of the brush cylinder 31, and an ion air knife 34 is provided on the side of the cleaning frame 32 facing the bottom frame 23; dust collection troughs 35 are respectively installed on both sides of the cleaning frame 32.

[0080] Ion air knives are installed on the bottom cleaning mechanism, the side cleaning structure, and the large surface cleaning mechanism. Ion air knives are specialized equipment that uses a high-voltage ion generator to produce positive and negative ions and uses compressed air to form a high-speed airflow to blow the ions onto the surface of the object to neutralize static electricity and remove dust. This equipment is existing.

[0081] like Figure 8 As shown, the attitude conversion and transfer mechanism 6 includes an attitude frame 61, and a movable slide rail 62 is provided on the side of the attitude frame 61 facing the frame 12; a lifting component 63 is installed on the movable slide rail 62, a rotating component is installed at the bottom of the lifting component 63, and an attitude manipulator is installed at the bottom of the rotating component.

[0082] In this embodiment and in Embodiment 1, both lifting components one and two are used to achieve the lifting effect of the robotic arm. Lifting component one includes a top block and a lifting cylinder. The top block and the corresponding track provide lateral movement and upward constraint, which can be referenced from the connection structure of an I-beam and a C-shaped slider. The output end of the lifting cylinder is fixed upward to the top block, so that when pneumatic input is applied, the cylinder body of the lifting cylinder moves downward, thereby lowering the side robotic arm. Similarly, reversing the direction of rotation achieves the raising of the side robotic arm. See [reference needed]. Figure 2 .

[0083] Lifting component two, then as follows Figure 8 As shown, it includes a top cylinder and a side guide rail. A sliding plate is installed at the output end of the top cylinder. A slider is positioned inward on the sliding plate and slides on the side guide rail, constraining it so that it cannot detach. A synchronous positioning frame is installed on the outer side of the sliding plate. The synchronous positioning frame is a combination of two sets of trapezoidal plates and a bottom plate.

[0084] like Figure 9 As shown, the rotating component includes a servo motor 64 and a bending plate 65. The output end of the servo motor 64 is coaxially connected to the reducer 66. A synchronous positioning frame 69 is installed on the outside of the lifting component 63. A position plate 67 and a positioning plate 68 are detachably installed on the bottom of the synchronous positioning frame 69.

[0085] The output end of the reducer 66 passes through the position plate 67 and the bending plate 65 and is connected to the positioning plate 68;

[0086] The output ends of the bending plate 65 and the reducer 66 are fixedly connected. A gap is provided between the position plate 67 and the bending plate 65. This gap means that the bending plate will not interfere with the servo motor and the reducer, so that the bending plate can rotate and thus the outer pneumatic gripper 2 can rotate. A pneumatic gripper 2 610 is installed at the bottom of the bending plate 65, and a product detection sensor 2 611 is installed on the gripper body at the bottom of the pneumatic gripper 2 610.

[0087] The lithium batteries are first transported in groups of one or two to the middle of two bottom cleaning mechanisms. A side robotic arm moves downwards to clamp the batteries, moving them from the center to both sides. The bottom surface is cleaned by the bottom cleaning mechanism, and the sides are cleaned by the side cleaning mechanisms. They are then placed on a support platform and clamped by a large-area robotic arm for large-area cleaning. The lithium batteries then move to the rear of the large-area transfer mechanism, where a second pneumatic gripper clamps their sides from the side, flipping them from vertical to horizontal during movement. The lithium batteries can then be transported or stacked.

[0088] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
