Description

Technical Field

[0001] This invention relates to the field of battery assembly technology, and more specifically, to a lithium battery module assembly machine. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. They are currently the primary power source for modern digital products such as mobile phones and laptops. In the automotive sector, lithium-ion batteries are gradually replacing traditional gasoline and diesel engines as one of the power sources for automobiles. Electric vehicles have thus become an important product in China's new energy vehicle market. Electric vehicles are currently the only motor vehicles in the world that can achieve zero emissions, meeting the increasingly important environmental protection requirements both domestically and internationally. With the continuous depletion of fossil fuels, the future automotive market will inevitably be dominated by electric vehicles.

[0003] Among them, the patent with announcement number CN205882088U discloses a lithium battery module assembly machine. The assembly machine body includes a frame with an assembly station inside. The assembly station is equipped with a tooling plate. The lithium battery is modularly assembled on the tooling plate. A material conveyor and a battery conveyor are provided outside the frame.

[0004] When in use, this structure uses a battery gripper to pick up lithium batteries from the battery conveyor and place them onto a plastic part for assembly, and a material gripper to pick up plastic parts from the material conveyor and place them onto a tooling plate. The material is picked up and placed into the plastic part for assembly. However, the gripping method cannot ensure that battery materials such as lithium iron phosphate and ternary materials are accurately put into the battery casing, and it is not easy to automatically eject the assembled material for retrieval, which is not convenient to use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lithium battery module assembly machine, which aims to solve the problems mentioned in the background art.

[0006] The present invention provides the following technical solution: a lithium battery module assembly machine, including a base, wherein a material guiding and processing component is provided on the base;

[0007] The material guiding and processing assembly includes a slide plate disposed on the top of the base, a material support rod disposed at one end of the slide plate, a connecting frame covering the end of the slide plate away from the material support rod, a limit sleeve disposed at the top of the connecting frame, and a misalignment opening provided at the bottom of the connecting frame;

[0008] A positioning cylinder is embedded in the middle of the base, located directly below the material support rod. A spring is embedded inside the positioning cylinder, and a top plate is provided at the top of the spring. The material support rod is slidably connected to the slide plate, and the bottom end of the material support rod extends to the top of the top plate.

A gathering hopper is provided at the top of both the baffle and the discharge frame, and the gathering hopper is connected to the guide groove. A diversion hopper is provided on one side of the base, and one end of the diversion hopper is inclined downward.

[0009] Optionally, in a possible implementation, one end of the base is provided with a first electric push rod for driving the slide plate to move; a connecting frame is slidably connected to the outer side of the slide plate; a second electric push rod for driving the limiting sleeve to move is provided on the connecting frame; two discharge ports are opened on one side of the guide hopper, and the discharge ports are located on the top side of the gathering hopper; a baffle block is slidably connected in each of the two discharge ports; a third electric push rod for driving the baffle block to move up and down is provided on one side of the guide hopper; a reinforcing frame is provided on one side of the base; a fourth electric push rod is provided on the top of the reinforcing frame; the fourth electric push rod... The output end of the push rod is equipped with a pressure head. The top of the inner cavity of the reinforcing frame is equipped with a fifth electric push rod. The output end of the fifth electric push rod is equipped with a horizontal plate. An extension plate is slidably connected to the horizontal plate. A pusher plate is provided at one end of the extension plate. A side plate is provided on one side of the horizontal plate. The side plate is bolted to one side of the inner wall of the reinforcing frame. A long waist hole is opened through the side plate. The top of the inner cavity of the long waist hole is vertically downward. A pulley installed on one side of the extension plate is slidably connected in the long waist hole. A guide plate is provided on one side of the top of the side plate. The guide plate extends to the bottom of the pressure head.

[0010] The technical effects and advantages of this invention are as follows:

[0011] 1. This invention utilizes the coordinated design of a guide hopper, a gathering hopper, and a guide trough. The material discharged from the guide hopper is gathered by the gathering hopper and then precisely guided to the battery cells on the support rod via the guide trough of the discharge frame, ensuring the accuracy of material delivery. Simultaneously, the baffle block on one side of the guide hopper can adjust the opening of the discharge port under the drive of a third electric push rod, achieving precise control of material flow, further improving the guiding accuracy, ensuring the assembly accuracy of battery materials, and avoiding instability in battery voltage caused by differences.

[0012] 2. This invention features a positioning cylinder in the center of the base, with the top of a spring connected to the top plate and the bottom of the material support rod in contact with the top plate. After the pressure head presses down to complete the assembly, the elastic force of the spring pushes the top plate upward, thereby causing the material support rod to return to its original position and automatically ejecting the assembled battery. This eliminates the need for manual demolding and significantly improves the convenience of material handling.

[0013] 3. The invention features a first electric push rod that drives the sliding plate to move and connect the battery cell to the guide plate; a second electric push rod that adjusts the position of the connecting frame and the limiting sleeve to ensure that the battery casing and the battery cell are coaxially aligned; a fourth electric push rod that drives the pressure head to complete the pressure assembly; and a fifth electric push rod that works with the extension plate and the push plate to automatically push the finished product. The entire process is automated, reducing manual intervention and significantly improving assembly efficiency.

[0014] In summary, through the coordinated use of various structures, the material guide trough of the feeding frame precisely guides the battery cells onto the support rod, ensuring accurate material conveying. The adjustable opening of the discharge port enables precise control of material flow, further improving guiding accuracy and ensuring battery material assembly precision. This prevents instability in battery voltage caused by differences. The elastic force of the spring pushes the top plate upward, thereby resetting the support rod and automatically ejecting the assembled battery, eliminating the need for manual demolding and significantly improving material handling convenience. The pressure head completes the pressure assembly. The fifth electric push rod, in conjunction with the extension plate and pusher plate, enables automatic pushing of finished products. The fully automated operation reduces manual intervention, greatly improving assembly efficiency and offering both ease of use and excellent practicality. Attached Figure Description

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] As attached Figure 1 - Figure 8 The lithium battery module assembly machine shown uses a material guiding processing component on the base 1 to precisely guide the battery cells on the support rod 3 through the material guide groove 11 of the unloading frame 10, ensuring the accuracy of material conveying. At the same time, the baffle block 18 on one side of the guide hopper 9 can adjust the opening of the discharge port 17 under the drive of the third electric push rod 19, realizing precise control of material flow, further improving the guiding accuracy, ensuring the assembly accuracy of battery materials, and avoiding differences that may cause unstable battery voltage. The specific structural settings of the components are as follows.

[0027] The material guiding and processing assembly includes a slide plate 2 mounted on top of the base 1. A material support rod 3 is mounted at one end of the slide plate 2. A connecting frame 4 is mounted on the end of the slide plate 2 furthest from the material support rod 3. A limit sleeve 5 is mounted at the top of the connecting frame 4, and a misalignment opening 27 is provided at the bottom of the connecting frame 4. (See attached diagram.) Figure 7As shown, the support rod 3 facilitates the placement of battery cells, while the limiting sleeve 5 facilitates the placement of battery casings by workers. This allows the battery casing and cells to be assembled together when the connecting frame 4 and the limiting sleeve 5 move the battery casing to the top of the support rod 3. A positioning cylinder 6 is embedded in the middle of the base 1, located directly below the support rod 3. A spring 7 is embedded inside the positioning cylinder 6, and a top plate 8 is located at the top of the spring 7. The support rod 3 is slidably connected to the sliding plate 2, and the bottom end of the support rod 3 extends to the top of the top plate 8. (See attached diagram.) Figure 7 As shown, when the material support rod 3 moves downward, its bottom end abuts against the top plate 8 and compresses the spring 7. The spring 7 itself drives the material support rod 3 to reset, so as to lift the battery and make it easier to demold the assembled battery.

[0028] A guide hopper 9 is provided at one end of the base 1, a discharge frame 10 is provided on one side of the bottom of the guide hopper 9, a baffle 12 is provided on one side of the discharge frame 10, and a guide groove 11 is provided on the discharge frame 10, as shown in the attached figure. Figure 8 As shown, the guide hopper 9 facilitates the delivery of the raw materials required for the battery into the discharge frame 10, and the guide trough 11 guides the battery raw materials; both the baffle 12 and the top of the discharge frame 10 are equipped with a gathering hopper 13, and the gathering hopper 13 is connected to the guide trough 11, as shown in the attached figure. Figure 8 As shown, the gathering hopper 13 facilitates the gathering of battery raw materials discharged from the guide hopper 9, ensuring the accuracy of battery raw material discharge.

[0029] One end of the base 1 is provided with a first electric push rod 14 for driving the displacement of the slide plate 2. A connecting frame 15 is slidably connected to the outside of the slide plate 2. A second electric push rod 16 for driving the displacement of the limiting sleeve 5 is provided on the connecting frame 15, as shown in the attached figure. Figure 4 As shown, the slide plate 2 is driven to move by the first electric push rod 14 so that the slide plate 2 can move to the bottom of the feeding frame 10, so that the material in the guide groove 11 can fall into the battery cell placed on the support rod 3. The connecting frame 4 and the limiting sleeve 5 are driven to move by the second electric push rod 16 so that the position of the connecting frame 4 and the limiting sleeve 5 can be adjusted so that the battery casing can be placed in the limiting sleeve 5 and the position of the connecting frame 4 and the support rod 3 can be adjusted so that the battery cell and the battery casing can be perpendicular.

[0030] Two discharge ports 17 are provided on one side of the guide hopper 9, and the discharge ports 17 are located on the top side of the gathering hopper 13. A baffle block 18 is slidably connected inside each discharge port 17. A third electric push rod 19 is provided on one side of the guide hopper 9 for driving the baffle block 18 to move up and down, as shown in the attached figure. Figure 8 As shown, the material in the guide hopper 9 is discharged through the discharge port 17. The material blocking block 18 is moved by the third electric push rod 19 to adjust the opening size of the discharge port 17, thereby adjusting the flow rate of the discharged material.

[0031] A reinforcing frame 20 is provided on one side of the base 1, and a fourth electric push rod 21 is provided on the top of the reinforcing frame 20. A pressure head 22 is provided at the output end of the fourth electric push rod 21, as shown in the attached figure. Figure 1 , 2 As shown in Figure 6, the pressure head 22 is driven downward by the fourth electric push rod 21, so that when the pressure head 22 abuts against the battery casing, the battery casing and the battery cell are fitted together; a fifth electric push rod 23 is provided at the top of the inner cavity of the reinforcing frame 20, and a horizontal plate 24 is provided at the output end of the fifth electric push rod 23. An extension plate 25 is slidably connected to the horizontal plate 24, and a pusher plate 26 is provided at one end of the extension plate 25, as shown in the attached figure. Figure 6 As shown, the fifth electric push rod 23 drives the horizontal plate 24, which in turn moves the extension plate 25 and the pusher plate 26, so that the pusher plate 26 can abut against the outside of the assembled battery case, facilitating the ejection of the assembled battery. A side plate 28 is provided on one side of the horizontal plate 24. The side plate 28 is bolted to one side of the inner wall of the reinforcing frame 20, and a long, narrow hole 29 is provided through the side plate 28. The top of the inner cavity of the long, narrow hole 29 points vertically downwards, and a pulley mounted on one side of the extension plate 25 is slidably connected inside the long, narrow hole 29. (See attached diagram.) Figure 6 As shown, when the horizontal plate 24 moves up and down, the pulley rubs against the elongated hole 29. When the pulley is in the vertical elongated hole 29, the pulley is pushed by the force to move the extension plate 25 and the pusher plate 26 along the guide of the horizontal plate 24, so that the pusher plate 26 can abut against the assembled battery. When the horizontal plate 24 moves upward, the pulley moves into the inclined elongated hole 29, so that the extension plate 25 and the pusher plate 26 can be reset. A guide plate 30 is provided on one side of the top of the side plate 28. The guide plate 30 extends to the bottom of the pressure head 22, as shown in the attached figure. Figure 6 As shown, the guide plate 30 is used to guide the displacement stroke of the pressure head 22, ensuring the stability of the pressure head 22 during displacement; a guide hopper 31 is provided on one side of the base 1, with one end of the guide hopper 31 inclined downwards, as shown in the attached figure. Figure 1 As shown, the guide bucket 31 is used to guide the assembled batteries.

[0032] The specific working principle is as follows: battery raw materials, such as positive electrode materials and separators, are fed into the feed hopper 9, as shown in the attached diagram. Figure 5 , 8 As shown. The third electric push rod 19 drives the baffle block 18 to move up and down within the discharge port 17, adjusting the opening of the discharge port 17 to control the amount of raw material discharged; the raw material falls into the gathering hopper 13 through the discharge port 17, and after being gathered by the gathering hopper 13, it enters the guide trough 11 of the feeding frame 10, and is guided to the bottom of the feeding frame 10 through the guide trough 11, thus completing the precise delivery of the raw material.

[0033] Place the battery cell at the top of the material support rod 3, as shown in the attached diagram. Figure 7As shown. The first electric push rod 14 is activated, driving the slide plate 2 to slide along the top of the base 1 until the material support rod 3 is moved to the bottom of the unloading frame 10; at this time, the raw material in the guide groove 11 falls into the battery cell on the material support rod 3 along the groove, completing the raw material loading of the battery cell.

[0034] Place the battery casing inside the limiting sleeve 5, as shown in the attached document. Figure 7 As shown in the attached diagram. The second electric actuator 16 drives the connecting frame 4 to displacement. Figure 2 and 4 As shown, the misalignment opening 27 at the bottom of the connecting frame 4 corresponds to the position of the material support rod 3, so that the battery casing inside the limiting sleeve 5 and the battery cell on the material support rod 3 are kept coaxially aligned, in preparation for subsequent assembly.

[0035] The first electric push rod 14 drives the slide plate 2 to move again, moving the aligned battery cell and housing directly below the pressure head 22, as shown in the attached figure. Figure 1 , 6 As shown. The fourth electric push rod 21 is activated, driving the pressure head 22 to move vertically downward along the guide plate 30, as shown in the attached figure. Figure 6 As shown, the pressure head 22 abuts against the top of the battery casing and applies pressure, causing the casing to fit tightly against the battery cell; during this process, the material support rod 3 slides downward along the slide plate 2 under pressure, and its bottom end presses against the top plate 8, causing the spring 7 inside the positioning cylinder 6 to compress, as shown in the attached diagram. Figure 7 As shown. After assembly, the fourth electric push rod 21 drives the pressure head 22 to move upward and reset, the spring 7 elastically resets and pushes the top plate 8 upward, which in turn drives the material support rod 3 upward, pushing the assembled battery out to the initial height, completing the automatic demolding.

[0036] The fifth electric push rod 23 is activated, driving the horizontal plate 24 to move downwards, as shown in the attached diagram. Figure 3 , 6 As shown. The horizontal plate 24 drives the extension plate 25 to move downwards synchronously. The pulley on one side of the extension plate 25 slides along the elongated hole 29 of the side plate 28. The vertical section of the elongated hole 29 guides the pulley to move horizontally, causing the extension plate 25 to slide along the horizontal plate 24 towards the battery, thereby pushing the pusher plate 26 to contact the assembled battery. The pusher plate 26 pushes the battery to the guide hopper 31 on one side of the base 1. The battery slides out along the inclined guide hopper 31, completing the automatic output of the finished product. Subsequently, the fifth electric push rod 23 drives the horizontal plate 24 to move upwards and reset. The pulley slides along the inclined section of the elongated hole 29, driving the extension plate 25 and the pusher plate 26 to reset, waiting for the next assembly cycle.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
