Description

Technical Field

[0001] This invention relates to the field of battery formation and capacity testing equipment, and more particularly to a chain-type capacity testing cabinet. Background Technology

[0002] With the rapid development of electric vehicles and renewable energy, the demand for cylindrical batteries is increasing, leading to higher requirements for battery manufacturing technology and equipment. Currently, most cylindrical battery formation and capacity testing equipment in the market still uses open, single-machine, manual equipment. While this has certain advantages, it also has some drawbacks. First, this equipment consists of independent machines or areas, requiring workers to place batteries one by one into battery trays, and then place the trays layer by layer into the testing positions of the equipment. This operation method results in low production efficiency and requires a large amount of manual labor. Each worker needs to operate a different machine or testing position and constantly monitor the equipment's operating status and battery quality, making the operation very cumbersome. This manual operation mode limits the improvement of production capacity and efficiency.

[0003] However, with continuous technological development and innovation, the development of cylindrical battery formation and capacity testing equipment is making some significant breakthroughs. Some manufacturers have begun to offer a degree of automated production line capacity testing operations by introducing technologies such as robots and automated conveyor belts. Its design goal is to improve production efficiency, reduce manual operation, and ensure the accuracy and quality of battery formation. However, existing automated production line capacity testing equipment still has some problems. Firstly, the formation and capacity testing cabinets involve numerous intricate details and complex components. In particular, some equipment designs require a large number of sensing elements to work with complex mechanical parts to achieve the desired action. These sensors and actuators are susceptible to environmental changes and mechanical failures, leading to increased equipment failure rates and frequent additional repair and maintenance work.

[0004] Therefore, existing fractionation capacity cabinets require further optimization and improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a chain-type capacity cabinet that is reasonably designed, has simple and efficient mechanical coordination, and does not require a large number of sensors and actuators to work together.

[0006] To achieve the above objectives, the present invention adopts the following solution: a chain-type capacity-dividing cabinet, comprising...

[0007] A rack having at least one layer of compartments within it;

[0008] A conveyor line is installed inside the compartment, and both ends of the conveyor line extend to the outside of the frame, with a drive motor installed at one end of the conveyor line.

[0009] A plurality of battery trays are arranged in sequence along the conveying line surface, each of the battery trays is provided with battery slots arranged in sequence along the length direction of the battery tray, and is used for accommodating batteries;

[0010] A power module is arranged inside the separate container compartment and located above the conveying line, a plurality of needle row assemblies are arranged in sequence and spaced apart at the bottom of the power module, and are used for clamping the positive and negative poles of the batteries carried on the corresponding battery tray below;

[0011] A jacking mechanism is arranged on the rack where each separate container compartment is located, and the jacking mechanism can move the corresponding power module up and down relative to the conveying line below.

[0012] A clamping assembly is arranged on the power module, and the clamping assembly can drive the needle row assembly to clamp or separate after the power module is moved downward by the jacking mechanism.

[0013] Through the above scheme, the automatic formation operation can be realized without a large number of inductive elements cooperating with complex mechanical parts, and the equipment failure rate and additional maintenance and maintenance work are reduced.

[0014] As a further aspect of the present application, the power module comprises a rectangular carrying frame accommodated in the separate container compartment, the needle row assembly is arranged on the bottom surface of the carrying frame, the power module is arranged on the carrying frame, and the power module is arranged on the carrying frame. The power supply board electrically connected with the corresponding needle row assembly is arranged on the top of the carrying frame, the clamping assembly is arranged on the carrying frame, and the supporting shafts are respectively and symmetrically extended outward on the left and right sides of the carrying frame. The jacking mechanism is connected with the supporting shafts through the connecting assembly.

[0015] As a further aspect of the present application, the needle row assembly comprises a fixed beam transversely fixed on the bottom of the carrying frame, a movable beam capable of moving forward and backward is arranged on one side of each fixed beam on the bottom of the carrying frame, the movable beam is relatively moved with the corresponding fixed beam through the clamping assembly, a plurality of negative pole pins corresponding to the number of battery slots below are arranged in sequence and spaced apart along the length direction of the fixed beam, a positive pole pin corresponding to the negative pole pin is arranged on the movable beam, and the positive pole pin and the negative pole pin are respectively electrically connected with the corresponding power supply board through a cable.

[0016] By relatively folding or separating the movable beam and the fixed beam corresponding to each battery tray, batch clamping formation of the battery can be realized.

[0017] As a further aspect of the present application, the clamping assembly comprises a linkage pull rod arranged on the left and right sides of the carrying frame and capable of moving forward and backward along the carrying frame, a clamping cylinder capable of being connected with the linkage pull rod is arranged on the carrying frame, and the linkage pull rod is connected with the two ends of the movable beam.

[0018] As a preferred embodiment of the present application, the clamping cylinders are respectively hinged on the side frames on the left and right sides of the bearing frame, and a clamping connecting rod is hinged on the end of the piston rod of each clamping cylinder, and a drive gear is arranged on the end of the clamping connecting rod away from the piston rod of the clamping cylinder, and the drive gear is hinged on the side frame of the bearing frame, and a rack capable of meshing with the drive gear is fixed on the connecting rod. Through simple gear and rack meshing, the clamping and separation of a large number of batteries can be effectively realized, and the complexity of equipment parts is reduced. The clamping cylinder connected through the connecting rod can convert the force generated by the piston rod into more uniform pushing force, so that more stable pushing is realized. Compared with direct connection, the pushing force is more stable, the sudden change and impact of the force are reduced, and the impact of the positive and negative pins on the battery is prevented.

[0019] As a preferred embodiment of the present application, a coaxial clamping synchronization rod is connected between the drive gears on the side frames on the left and right sides of the bearing frame, so as to ensure the balance of the clamping force of the battery.

[0020] As a further embodiment of the present application, guide rails are vertically arranged at four corners of the frame where the jacking mechanism is located, and a floating support block is arranged on each guide rail and can slide up and down, and an insertion hole capable of accommodating the support shaft is arranged on the floating support block, and the insertion hole is a horizontal or vertical strip-shaped hole, and the jacking mechanism comprises jacking cylinders arranged on the corresponding frame at four corners of the storage compartment, and the piston rod of the jacking cylinder is connected with the floating support block at the corresponding position. The cooperation of the guide rail and the floating support block reduces the shaking during the up and down movement of the power module and is more stable. The strip-shaped hole design of the insertion hole can ensure that the power module has a certain fault tolerance space when the bearing frame is unbalanced during the up and down movement, so that the power module is not stuck and the equipment is not damaged and stopped.

[0021] As a preferred embodiment of the present application, the jacking cylinder is hinged on the frame, a jacking connecting rod is hinged on the floating support block, the jacking connecting rod is hinged with the piston rod of the jacking cylinder, and a limiting connecting rod is hinged on the hinge shaft where the jacking connecting rod is hinged with the piston rod of the jacking cylinder, and the other end of the limiting connecting rod is hinged downward on the frame. The combined hinge of the jacking connecting rod and the limiting connecting rod can separate the vibration and impact of the jacking cylinder and transfer the force generated thereby to other components, thereby reducing the wear of the cylinder and the piston rod. This helps to improve the service life and working efficiency of the cylinder and piston rod and reduce the failure rate of the equipment.

[0022] As a preferred embodiment of the present application, a jacking synchronization connecting rod capable of synchronous rotation is connected between the limiting connecting rod on one side and another limiting connecting rod on the opposite side, and each jacking synchronization connecting rod is hinged with the limiting connecting rod at the position and the frame through a hinge shaft concentric with the frame.

[0023] As a preferred embodiment of the present application, height limiting seats are arranged on the frame under each floating support block, and adjusting bolts are arranged vertically on the height limiting seats through threaded connection, the top of the adjusting bolt can abut against the bottom of the corresponding floating support block, a reset spring is connected to the top of each floating support block, and the top end of the reset spring is anchored on the frame at the top of the corresponding sub-tank.

[0024] In summary, the present application has the following advantages over the prior art: The present application proposes a scheme of loading and unloading through multiple rows of battery trays arranged on the chain, realizing pipeline type full-automatic loading and unloading operation of cylindrical batteries. Compared with the traditional vertical loading and unloading mode of batteries, this scheme is more suitable for large-batch automatic battery formation process, and can significantly improve production efficiency. In addition, the present application provides a strip-shaped hole on the floating support block connected to the lifting mechanism of the power module carrier frame, to increase the fault tolerance space during lifting. This can effectively avoid the situation that the front and rear of the power module are not balanced due to the failure of multiple lifting cylinders to fully and accurately cooperate with each other during the operation of the battery separation equipment, thereby preventing the equipment from being stuck. In addition, a clamping synchronization rod is arranged on the clamping assembly that drives the positive and negative thimble to clamp each other, to keep the balance of the battery clamping force. This design can effectively reduce the failure of battery formation caused by the failure of the positive and negative thimble to fully adhere to the two poles of the battery during battery formation. Finally, a reset spring is arranged on each floating support block connected to the power module. In this way, when the air supply of the battery separation cabinet is accidentally disconnected, the reset spring can lift the power module to take out the battery in the battery separation tank, thereby effectively preventing the battery from being damaged. In view of the above, the scheme proposed by the present application realizes pipeline type full-automatic formation operation of cylindrical batteries through the design of multiple rows of battery trays and chain conveying, the strip-shaped hole of the floating support block, the clamping synchronization rod and the reset spring, and solves the problems of imbalance, formation failure and damage that may occur during operation. This scheme does not require a large number of sensing elements to cooperate with complex mechanical components to realize automatic formation operation, reduces the increase of formation equipment failure rate, and further reduces additional repair and maintenance work.

Thus, a feature specified as "first" can be interpreted as a "second" feature, and vice versa.

[0042] The application will be further described with reference to the drawings and specific examples in which: Figures 1 to 14The chain type battery distribution cabinet comprises a frame type rack 1, three layers of battery distribution bins 11 are arranged in the rack 1, conveying lines 2 are arranged in the three layers of battery distribution bins 11 respectively, the conveying lines 2 are chain type conveying lines, and the front and rear ends of the conveying lines 2 extend to the outside of the rack 1 respectively. Specifically, the conveying line 2 comprises a horizontal rectangular frame 24, chains 25 arranged on the left and right sides of the rectangular frame 24 respectively and a driving motor 23 arranged at one end of the rectangular frame 24.

The first row of battery trays 21 on one side of the conveying line 2 close to the driving motor 23 is arranged as a discharging position, and the last row (that is, the 18th row) is arranged as a feeding position. A battery groove 22 for accommodating a battery 10 is arranged on each battery tray 21 in sequence along the length direction of the battery tray 21. When working, the battery 10 is loaded into the battery groove 22 from the feeding position of one end of the conveying line 2 extending to the outside of the rack 1 by an external mechanical arm. The battery groove 22 is concave and arc-shaped, and a plurality of magnets are arranged on the inner wall of the battery groove 22 to adsorb the outer wall of the battery 10 loaded therein. After each row of battery grooves 22 is loaded, the driving motor 23 drives the chain wheel 26 to drive the chain 25 and the battery tray 21 to move forward by a distance L to the first row (the discharging position), and the same operation is repeated gradually until 16 rows (except the first row and the last row) of battery trays 21 in the battery distribution bin 11 are loaded with the batteries 10. A power module 3 is arranged above the conveying line 2 in each battery distribution bin 11, a jacking mechanism 6 is arranged on the rack 1 of each battery distribution bin 11 and can lift the power module 3 up and down relative to the conveying line 2 below the power module 3. A plurality of needle row assemblies 4 are arranged on the bottom of the power module 3 in sequence and at intervals. After the batteries 10 on one side of the conveying line 2 in each layer of battery distribution bin 11 are loaded, the jacking mechanism 6 lowers the power module 3 to the conveying line 2 below, stops when the needle row assembly 4 is aligned with the battery 10, and each needle row assembly 4 clamps the positive and negative electrodes of the battery 10 carried in the corresponding battery groove 22 below through the clamping assembly 5 arranged on the power module 3 to perform formation and distribution operation.When the sorting operation is completed, each needle row assembly 4 is released from clamping the positive and negative electrodes of the battery 10 by the clamping assembly 5 provided on the power module 3, the lifting mechanism 6 with the power module 3 starts to rise, then the driving motor 23 drives the chain wheel 26 to make the chain 25 take the battery tray 21 to move the battery tray 21 in the sorting bin 11 row by row out of the rack 1 (discharging position), and then the robot takes away the battery 10 on the battery tray 21 moved out of the rack 1.

In addition, height limiting seats 8 are arranged on the rack 1 below the floating support blocks 71, adjusting bolts 81 are vertically arranged on the height limiting seats 8 through threaded connection, the top of the adjusting bolt 81 can abut against the bottom of the corresponding floating support block 71, and the descending height of the power module 3 is controlled by rotating the adjusting bolt 81.

[0045] As shown in Figure 14 In order to prevent the left and right clamping air cylinders 52 from being out of sync and ensure that the left and right ends of the movable beams 42 move synchronously, a clamping synchronous rod 56 with the same axis is connected between the driving gears 54 in the square tubes on the left and right sides of the bearing frame 31 to keep the balance of the clamping force on the battery 10.
