Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery production, in particular to a new energy battery cell feeding and discharging mechanism. BACKGROUND

[0002] The production process of new energy battery cells is extremely complex, covering winding / stacking, welding, liquid injection, formation, capacity distribution, and a series of strict performance and safety tests. Moreover, the process does not flow linearly at a fixed pace. There is often a discontinuous buffer period between the completion of the previous process and the start of the next process. The battery cells need to be temporarily stored and circulated. Therefore, the battery cell feeding and discharging device becomes the core hub connecting discrete processes and ensuring smooth operation of the entire line.

[0003] A patent application CN119330063A discloses a battery cell feeding and discharging workstation. The technical solution is as follows: a frame, a first tray, a second tray, and a battery cell gripper. The first tray is used to store test battery cells. The second tray is used to store qualified battery cells and unqualified battery cells. The battery cell gripper is movably arranged on the frame to move the unqualified test battery cells on the first tray to the second tray or move the qualified battery cells on the second tray to the first tray. The battery cell gripper includes a first driving member, a rotating mechanism, and a clamping mechanism. The first driving member is arranged on the frame. The driving end of the first driving member is connected with the rotating mechanism to drive the rotating mechanism and the clamping mechanism to move in the first direction. The rotating end of the rotating mechanism is connected with the clamping mechanism to drive the clamping mechanism to rotate. The clamping mechanism is suitable for clamping battery cells.

[0004] However, the above-mentioned technology often has the following defects: the mechanical hand or clamp operation mode used by the existing battery cell feeding and discharging mechanism has obvious limitations. Its main disadvantage is that it cannot realize continuous operation. The mechanical hand or clamp can only carry a single or limited batch of battery cells each time. There is a lot of idle waiting time in the operation process, which leads to low overall efficiency and makes it difficult to match the production pace of high-speed production lines. This intermittent feeding and discharging mode not only limits the capacity improvement but also increases the frequency of equipment start and stop, aggravating the wear and tear of the mechanism and energy consumption. In addition, due to the need for repeated positioning and grabbing, the positioning accuracy and repeatability are extremely high. Any deviation may affect the placement accuracy of the battery cells.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0034] As Figures 1 to 7 shown, the new energy electric core feeding and discharging mechanism provided by the application comprises a conveying device 1, a storage device 2 and a transfer device 3.

[0035] The storage device 2 comprises a support seat 21; the upper side of the support seat 21 is provided with a table plate 22; the surface of the table plate 22 is placed with a storage box 23.

[0036] The transfer device 3 is arranged between the conveying device 1 and the storage device 2; the transfer device 3 comprises a support frame 31; the lower side of the support frame 31 is rotationally connected with a pair of chain wheels 32, and the chain wheels 32 are driven by a motor 33; the surface of the chain wheels 32 is sleeved with a chain 34; the surface of the chain 34 is uniformly provided with a group of pick-and-place assemblies 4; the pick-and-place assemblies 4 are used for grabbing electric cores 7 and moving between the conveying device 1 and the storage device 2.

[0037] The mechanical hand or clamp operation mode adopted by the existing battery cell 7 feeding and discharging mechanism has obvious limitations, and its main defect is that it cannot realize continuous operation, and the mechanical hand or clamp can only carry single or limited batch of battery cells 7 each time, and there is a lot of idle waiting time in the operation process, which leads to low overall efficiency and is difficult to match the production rhythm of high-speed production line. This intermittent feeding and discharging mode not only limits the capacity improvement, but also increases the frequency of equipment start and stop, aggravates the wear and tear of the mechanism and energy consumption, in addition, due to the need for repeated positioning and grabbing, the positioning accuracy and repeatability are extremely high, and any deviation may affect the placement accuracy of the battery cell 7.

[0038] The present application sets up a transfer device 3 for battery cell 7 feeding and discharging between the conveying device 1 and the storage device 2, and drives the chain wheel 32 and the chain 34 by the motor 33, then the pick-and-place assembly 4 intermittently sweeps above the conveying device 1 and the storage device 2, so as to clamp or release the battery cell 7 by the pick-and-place assembly 4, which can transfer the battery cell 7 between the production line and the storage box 23, realize feeding and discharging operation, and the pick-and-place assembly 4 can clamp, transport and release single battery cell 7 without affecting other pick-and-place assemblies 4, no matter what state the device is in, there is always a pick-and-place assembly 4 that can participate in the feeding and discharging work, thereby realizing continuous operation, reducing idle waiting time and improving the overall production efficiency of the battery cell 7.

[0039] As one of the preferred embodiments of the present application, the support frame 31 is provided with a working position 35 on both sides of the conveying device 1 and the storage device 2 above the position; the working position 35 is fixedly connected with a gas cylinder 36; the output end of the gas cylinder 36 is fixedly connected with an electromagnet 37;

[0040] The pick-and-place assembly 4 comprises a sleeve 41 fixedly connected to the surface of the chain 34; the sleeve 41 is slidably connected with a lifting seat 42 inside; the lifting seat 42 is fixedly connected with a spring 43 between the upper side of the sleeve 41; the lifting seat 42 is fixedly connected with a connecting disc 44 through a connecting rod on the lower side; a group of control claws 45 are hinged on the side of the connecting disc 44; the connecting disc 44 is fixedly connected with a center column 46 on the lower side; the control claw 45 and the center column 46 are fixedly connected with a spring 47; a sliding cavity 48 is formed in the lifting seat 42; a magnetic block 49 is arranged in the sliding cavity 48; the control claw 45 and the magnetic block 49 are fixedly connected with a steel wire rope 50.

[0041] The movement speed of the sprocket 32 and the chain 34 is controlled by the motor 33, so that the speed of the pick-and-place assembly 4 and the conveying device 1 remains the same, and the two working positions 35 correspond to the conveying device 1 and the storage device 2 respectively and are used for feeding and discharging, the arrangement interval of the battery cells 7 on the surface of the conveying device 1 is equal to the interval of the adjacent pick-and-place assemblies 4, and when one of the battery cells 7 on the surface of the conveying assembly moves to the position directly below the working position 35, exactly one pick-and-place assembly 4 also moves to the working position 35, forming alignment of the working position 35, the pick-and-place assembly 4 and the battery cell 7.

[0042] When the discharging operation is implemented, the pick-and-place assembly 4 moves to the working position 35 above the conveying device 1, at this time the motor 33 and the conveying device 1 are temporarily stopped, the cylinder 36 of the working position 35 drives the electromagnet 37 to move downward into the sleeve 41 of the pick-and-place assembly 4 and press the lifting seat 42, the electromagnet 37 is controlled to be powered on and attract the magnetic block 49 in the lifting seat 42, which drives the magnetic block 49 to move upward in the sliding cavity 48, the magnetic block 49 pulls the control claws 45 upward through the steel wire rope 50, so that the control claws 45 are in an open state, then the cylinder 36 continues to elongate and drives the lifting seat 42, the connecting disc 44 and the control claws 45 to move downward, when the control claws 45 move downward to the outer periphery of the battery cell 7, the electromagnet 37 is powered off, then the spring 47 pulls the control claws 45 to the center to clamp the battery cell 7, then the cylinder 36 retracts to drive the electromagnet 37 to reset, and the spring 43 pulls the lifting seat 42, the connecting disc 44, the control claws 45 and the battery cell 7 to reset upward as a whole, so as to realize the grabbing of the battery cell 7 by the pick-and-place assembly 4, then the pick-and-place assembly 4 and the battery cell 7 move to the working position 35 above the storage device 2 along with the chain 34, at this time the motor 33 and the conveying device 1 are also temporarily stopped, the cylinder 36 of the working position 35 drives the magnetic block 49 to move downward and drives the lifting seat 42 to move downward, until the battery cell 7 enters the storage box 23, the electromagnet 37 is controlled to be powered on to attract the magnetic block 49, so as to open the control claws 45 and release the battery cell 7, then the cylinder 36 resets and the electromagnet 37 is powered off, so as to release the battery cell 7 by the pick-and-place assembly 4, thereby discharging and transferring the battery cell 7 on the production line to the storage box 23.

[0043] When the feeding operation is implemented, in order to transfer the battery cell 7 in the storage box 23 to the production line, the above operation is repeated in reverse, the pick-and-place assembly 4 grabs the battery cell 7 at the working position 35 of the storage device 2, and then moves to the working position 35 of the conveying device 1 to release the battery cell 7 to the surface of the conveying device 1.

[0044] The device can be flexibly configured according to the actual layout and beat demand of the production line, can adapt to the use demand of the feeding station or the discharging station alone, or can complete the feeding and discharging operation according to different demands at the same station. Through the program setting of the device in advance, the two completely different operations of grabbing and feeding and placing and discharging of the battery cell 7 are completed seamlessly. The device has high functional integration and scene adaptability in design, greatly expands the boundary of the application scene, and can easily cope with various complex demands such as production line transformation, process combination and flexible production.

[0045] As one of the preferred embodiments of the present application, the storage box 23 is uniformly distributed with a group of squares 24 for storing battery cells 7.

[0046] A double-shaft driving assembly is arranged between the table plate 22 and the support seat 21, and is used to control the horizontal and vertical axis translation movement of the table plate 22.

[0047] When the pick-and-place assembly 4 puts the battery cell 7 into the storage box 23 or clamps the battery cell 7 from the storage box 23, the double-shaft driving assembly controls the movement of the table plate 22 and the storage box 23 along the horizontal two-dimensional coordinate system through program setting, so as to sequentially align different squares 24 with the working position 35, cooperate with the working position 35 to release or clamp the battery cell 7, and thus realize the sequential storage or taking out of the battery cell 7 in each square 24 of the storage box 23. Each battery cell 7 is isolated from each other through the square 24, which reduces the possibility of collision and prevents the battery cell 7 from being damaged.

[0048] As one of the preferred embodiments of the present application, the center column 46 is fixedly connected with a suction cup 51 on the lower side. When the pick-and-place assembly 4 clamps the battery cell 7, the suction cup 51 can be synchronously adsorbed on the top surface of the battery cell 7, cooperate with the control claw 45 to grasp the battery cell 7, and further improve the clamping and conveying stability of the pick-and-place assembly 4 to the battery cell 7, and reduce the possibility of the battery cell 7 falling.

[0049] The magnetic block 49 is in sliding sealing fit with the sliding cavity 48, and the top of the sliding cavity 48 is in communication with the suction disc 51 through the conduit 52. During the process that the control claw 45 clamps the battery cell 7, the magnetic block 49 moves downward in the sliding cavity 48, at this time, the top of the sliding cavity 48 generates negative pressure, and the air between the suction disc 51 and the battery cell 7 is sucked through the conduit 52, so as to increase the vacuum degree in the suction disc 51 and improve the adsorption effect of the suction disc 51 on the battery cell 7. During the process that the control claw 45 releases the battery cell 7, the magnetic block 49 moves upward in the sliding cavity 48, then the magnetic block 49 squeezes the air at the top of the sliding cavity 48 and pushes the air into the suction disc 51 and the battery cell 7 through the conduit 52, so as to release the negative pressure environment in the suction disc 51 and realize the smooth separation between the suction disc 51 and the battery cell 7, which prevents the battery cell 7 from being brought up again after being released due to the excessive suction force of the suction disc 51. In addition, the suction disc 51 is easy to adhere to dust and other foreign matters on the inner side after long-term use, which will affect the adsorption effect. The air entering the suction disc 51 from the conduit 52 can blow and take away the foreign matters in the suction disc 51, so as to reduce the residual foreign matters.

[0050] The suction disc 51 is fixedly connected with a circular rubber sheet 53, and a gap is formed between the edge of the rubber sheet 53 and the inner side of the top of the suction disc 51. When the air enters the suction disc 51 from the conduit 52, the air can be blocked and guided by the rubber sheet 53, so as to guide the airflow to the inner side surface of the suction disc 51, thereby blowing and brushing the foreign matters attached to the inner side and making them fall off, so as to sufficiently enhance the blowing force of the airflow on the foreign matters and improve the cleaning effect of the suction disc 51.

[0051] As one of the preferred embodiments of the present application, the lower side of the support frame 31 is fixedly connected with a pair of groove boxes 6 through connecting plates; the groove boxes 6 are located below the pick-and-place assembly 4; recesses 61 are formed in the side surfaces of the groove boxes 6 at the positions of the movement paths of the pick-and-place assembly 4, and the recesses 61 are used for the battery cell 7 clamped by the pick-and-place assembly 4 to pass through. Except the pick-and-place assemblies 4 at the two working positions 35, the remaining pick-and-place assemblies 4 are located above the groove boxes 6, so that the groove boxes 6 can form falling protection for the battery cell 7 during the process that the pick-and-place assembly 4 transports the battery cell 7. If the battery cell 7 falls from the control claw 45 due to control disorder, structure damage, external intervention or other problems, the battery cell 7 can fall into the groove box 6, so as to prevent the battery cell 7 from falling to the ground and being damaged.

[0052] The groove box 6 is fixedly connected with an elastic pad 62; the elastic pad 62 is designed as a hollow structure and filled with air in the inside. The elastic pad 62 and the air in the inside can buffer the battery cell 7 falling into the groove box 6, so as to reduce the impact force and further protect the battery cell 7.

[0053] The elastic pad 62 is internally provided with an air pressure sensor 63; the air pressure sensor 63 is connected with an alarm 64 through a signal circuit. When the electric core 7 falls to the surface of the elastic pad 62, the air inside the elastic pad 62 is extruded, and then the air pressure sensor 63 detects the change of the pressure inside the elastic pad 62, controls the alarm 64 to send an alarm signal through the signal circuit, informs and reminds the relevant personnel to close the device in time and overhaul, so as to prevent the fault from further expanding.

[0054] The above front, back, left, right, up and down are based on the drawings in the specification Figure 1 As a standard, the side of the device facing the observer is defined as front, the left side of the observer is defined as left, and the like.
