[0002] The existing pole group wrapping mode in large lead-acid battery production plants all adopts manual wrapping, which is labor-intensive, low-efficiency, unstable quality, and easily causes lead powder to fly in the workplace, polluting the environment and endangering the physical and mental health of workers. When assembling battery pole groups, in addition to manual wrapping, there are many existing wrapping mechanisms, the most common of which is a swing suction mechanism powered by a cylinder. The swing suction mechanism is equipped with a vacuum suction cup, which reciprocates to suck and release the plates.

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figures 1 to 5 As shown, this application provides:

[0039] A battery pole group packaging machine for a large power battery, comprising a negative electrode plate feeding mechanism, a positive electrode plate feeding mechanism, a separator coil unloading mechanism, the positive electrode plate and the separator are packaged at the packaging mechanism, the positive electrode plate and the negative electrode plate after packaging are respectively transported through a conveying channel 1, the output end of the conveying channel 1 is provided with a feeding channel 2, the feeding channel 2 is inclined and the feeding end of the feeding channel 2 is higher than the discharging end, the conveying channel 1 and the feeding channel 2 for conveying the positive electrode plate are parallel to the conveying channel 1 and the feeding channel 2 for conveying the negative electrode plate. The receiving mechanism 3 is configured to stack the positive electrode plates and the negative electrode plates, and the receiving mechanism 3 includes a gantry 3a, on which a second adjusting arm 3b is fixedly mounted, a hinge seat 3b1 at the bottom of the second adjusting arm 3b is hingedly connected to a hinge head 3c1 at the top of the first adjusting arm 3c, and a receiving plate 3d is slidably mounted at the bottom of the first adjusting arm 3c, the receiving plate 3d is "L"-shaped, and an opening of the receiving plate 3d is arranged toward the discharge end of the material discharge channel 2, and the receiving plate 3d is used for sequentially receiving the positive electrode plates and the negative electrode plates that slide down from the material discharge channel 2.

[0040] Based on the above embodiments, the technical problem that the present application wants to solve is how to realize the stacking of positive and negative electrode plates so that they can quickly form the required electrode groups. To this end, the present application sets two conveying channels 1 arranged vertically to convey the positive electrode plates and the negative electrode plates respectively. The negative electrode plates are directly moved to the conveying channel 1 by the negative electrode plate feeding mechanism, and the positive electrode plates are fed by the positive electrode plate feeding mechanism, and the partitions cut from the folded partition coil material discharge mechanism are used to achieve the encapsulation movement during the movement. The plate wrapping mechanism is a common prior art and is relatively mature, so it will not be elaborated on here. After the plate is wrapped, the positive electrode plate moves to the conveying channel 1 on the upper side of the negative electrode plate and moves to the lower feeding channel 2. The conveying channel 1 can be a conveyor belt, and the unloading channel 2 is located at the output end of the conveying channel 1 and moves to the lower feeding channel 2 on the other side. The positive electrode plates and the negative electrode plates enter the material discharge channel 2 and slide down to the discharge end of the material discharge channel 2 under the action of gravity. When stacking, the first adjusting arm 3c and the second adjusting arm 3b of the receiving mechanism 3 rotate relative to each other, and the first adjusting arm 3c drives the receiving plate 3d to rotate around the axis of the hinge head 3c1, so that the bottom plate of the "L"-shaped receiving plate 3d rotates to a state parallel to the working surface of the material discharge channel 2, and the positive and negative electrode plates dropped on the conveying channel 1 are received. The receiving plate 3d can slide on the first adjusting arm 3c so as to move back and forth to the output ends of the material discharge channels 2 on the upper and lower sides, ensuring that it slides down on the material discharge channel 2. The electrode plates can stably enter the receiving plate 3d for stacking. The electrode plates can be intermittently transported by the conveying channel 1 and the time for the receiving plate 3d to move between the two discharge ends of the unloading channel 2 can be coordinated, so that the positive and negative electrode plates are staggered and moved to the unloading channel 2 to be received by the receiving plate 3d. Since the bottom plate of the receiving plate 3d is in an inclined state, the electrode plates are attached to one side of the receiving plate 3d under the action of gravity, thereby ensuring that the electrode groups formed by the stacking are stacked neatly. Since the conveying channel 1 and the unloading channel 2 for conveying the electrode plates are arranged up and down, the receiving plate 3d moves back and forth up and down when receiving the electrode plates, which has little effect on the stacked electrode plates, ensuring the neatness of the stacking. 1 and the unloading channel 2 are arranged horizontally. The left and right movement of the receiving plate 3d may cause the electrode plate on the receiving plate 3d to deviate under the action of inertia. At the same time, after the receiving plate 3d receives the electrode plate, its bottom plate position should be gradually lowered to ensure effective reception of subsequent electrode plates. The conveying channel 1 and the unloading channel 2 are arranged up and down to directly solve the technical problem. It is only necessary to set the stroke of each movement of the receiving plate 3d. After the electrode plates are stacked to form a pole group, the first adjusting arm 3c rotates to rotate the first adjusting arm 3c to a vertical state, and the bottom plate of the receiving plate 3d returns to a horizontal state, thereby driving the pole group to a horizontal state, which is convenient for moving the pole group to perform other steps such as film.

[0041] Further, such as Figure 4 As shown:

[0042] The material discharge channel 2 is composed of a plurality of rollers 2b installed on a mounting bracket 2a. The rotating axes of the rollers 2b are arranged horizontally. The rollers 2b are evenly spaced along the length direction of the mounting bracket 2a. Side baffles 2c with adjustable spacing are installed on both sides of the mounting bracket 2a.

[0043] Based on the above embodiments, the technical problem that this application wants to solve is how to ensure the smooth sliding of the electrode plate in the unloading channel 2. To this end, the unloading channel 2 adopted by this application is composed of a plurality of rollers 2b installed on the mounting bracket 2a. The rollers 2b convert the sliding friction generated when the electrode plate slides into rolling friction, avoiding the wear of the electrode plate and ensuring the smooth sliding of the electrode plate. The side baffles 2c set on both sides of the mounting bracket 2a can be adjusted accordingly according to the width of the electrode plate, ensuring that the electrode plates on the receiving plate 3d entering the receiving mechanism 3 are in the same position, further improving the neatness of the stacking of the pole group.

[0044] Further, such as Figure 6 and 7 As shown:

[0045] A first linear drive device 3c2 is fixedly installed on the side of the first adjusting arm 3c away from the discharge channel 2, and the working end of the first linear drive device 3c2 moves along the length direction of the first adjusting arm 3c. The working end of the first linear drive device 3c2 is fixedly installed on a connecting plate 3d1 arranged on the side of the receiving plate 3d away from the discharge channel 2, and a first guide rod 3d2 extending vertically upward is arranged on the upper side of the connecting plate 3d1, and the first guide rod 3d2 is inserted into the first guide sleeve 3c3 at the bottom of the first adjusting arm 3c.

[0046] Based on the above embodiments, the technical problem that the present application intends to solve is how the receiving plate 3d moves between the discharge ends of the two unloading channels 2 to receive the electrode plates. To this end, a first linear drive device 3c2 is fixedly installed on the first adjusting arm 3c of the present embodiment. The first linear drive device 3c2 can be a linear cylinder or an electric push rod, etc. The first linear drive device 3c2 pushes the receiving plate 3d installed at the bottom of the first adjusting arm 3c to move along the length direction of the first adjusting arm 3c. The first guide rod 3d2 on the connecting plate 3d1 on the receiving plate 3d is inserted into the first guide sleeve 3c3 at the bottom of the first adjusting arm 3c to achieve stability when the receiving plate 3d moves, thereby preventing the receiving plate 3d from shaking when receiving the electrode plate, which affects the neatness of the electrode group stacking.

[0047] Further, such as Figure 6 and 7 As shown:

[0048] On both sides of the second adjusting arm 3b below the gantry 3a, there are first slide rails 3b2 vertically arranged. First sliders 3b3 are slidably installed in the first slide rails 3b2. On the first sliders 3b3, there are first mounting posts 3b4 protruding outward. The first adjusting arm 3c and the second adjusting arm 3b are provided with fixed second mounting posts 3c4 on the same side of the first slide rails 3b2. The two ends of the connecting arm 3e are respectively inserted and connected to the first mounting post 3b4 and the second mounting post 3c4.

[0049] A connecting piece 3a1 is inserted into the gantry 3a. The connecting piece 3a1 moves vertically through a guiding hole 3a2 provided at the top of the gantry 3a. The connecting piece 3a1 is in a "C" shape with the opening facing downwards. The two ends of the connecting piece 3a1 are hinged to the first mounting posts 3b4 on the first sliders 3b3 on both sides of the second adjusting arm 3b. At the top of the gantry 3a, a second linear driving device 3a3 is fixedly installed. The working end of the second linear driving device 3a3 moves in the vertical direction. The working end of the second linear driving device 3a3 is fixedly installed with the connecting piece 3a1. The second linear driving device 3a3 is used to drive the first sliders 3b3 on both sides of the second adjusting arm 3b to slide along the first slide rails 3b2.

[0050] Based on the above embodiments, the technical problem that this application wants to solve is how to drive the first adjusting arm 3c to rotate so that the bottom plate of the material receiving plate 3d is inclined to a state parallel to the working surface of the blanking channel 2. For this purpose, the second adjusting arm 3b and the first adjusting arm 3c of this application are hingedly connected through the connecting arm 3e. One end of the connecting arm 3e is inserted into the first slider 3b3 that slides in the first slide rail 3b2, and the other end of the connecting arm 3e is inserted into the second mounting post 3c4 with a fixed position on the first adjusting arm 3c. When the first slider 3b3 moves vertically upward in the first slide rail 3b2, the first slider 3b3 drives one end of the connecting arm 3e to move upward, and the other end of the connecting arm 3e drives the first adjusting arm 3c to rotate around the axis of the hinge joint 3c1, so that the bottom plate of the material receiving plate 3d rotates to an angle parallel to the plane of the blanking channel 2. The first sliders 3b3 on both sides of the second adjusting arm 3b are connected to both ends of the connecting piece 3a1 installed on the gantry 3a. On the contrary, the downward movement of the first slider 3b3 drives the first adjusting arm 3c to rotate to the vertical state. The connecting piece 3a1 is inserted into the guiding hole 3a2 at the top of the gantry 3a to ensure a stable moving path in the vertical direction. The working end of the second linear driving device 3a3 at the top of the gantry 3a is fixedly connected to the connecting piece 3a1 to drive the connecting piece 3a1 to move up or down. The second linear driving device 3a3 can be a linear cylinder.

[0051] Further, as Figure 3 and 6 shown:

[0052] The two sides of the bottom of the gantry 3a are connected by a baffle 3a4, and the baffle 3a4 is arranged on the side of the receiving plate 3d away from the unloading channel 2. An elastic head 3f is installed on the baffle 3a4, and the elastic head 3f is arranged on the side of the baffle 3a4 facing the receiving plate 3d. The elastic head 3f is inserted into the insertion seat 3a5 set on the baffle 3a4 through the insertion rod 3f1. A limiting block 3f2 is set at the end of the insertion rod 3f1, and the limiting block 3f2 is set outside the insertion seat 3a5. A first spring 3f3 is mounted on the insertion rod 3f1, and the first spring 3f3 elastically connects the elastic head 3f and the insertion seat 3a5.

[0053] Based on the above embodiments, the technical problem that the present application aims to solve is that when the first adjusting arm 3c is in a vertical state, the connecting arm 3e is also in a vertical state. How to ensure that the upward movement of the first slider 3b3 can drive the first adjusting arm 3c to rotate toward the side of the unloading channel 2. To this end, the present application sets a baffle 3a4 at the bottom of the gantry 3a, and the baffle 3a4 is located on the side of the receiving plate 3d away from the unloading channel 2 to block the rotation angle of the receiving plate 3d. An elastic head 3f is installed on the receiving plate 3d. When the first adjusting arm 3c drives the receiving plate 3d to rotate to a vertical state, one side of the receiving plate 3d contacts the elastic head 3f and moves the elastic head 3f to the side of the baffle 3a4, compressing the first spring 3f3, so that the connecting arm 3e drives the first adjusting arm 3c to rotate to, and the first spring 3f3 provides the elastic force for the first adjusting arm 3c to rotate toward the side of the unloading channel 2, thereby ensuring the rotation direction of the receiving plate 3d. At the same time, the existence of the elastic head 3f also provides a deceleration when the receiving plate 3d rotates to a vertical state, and the pole group stacked on the receiving plate 3d vibrates, affecting the neatness.

[0054] Further, such as Figure 6 and 7 As shown:

[0055] The length of the bottom plate of the receiving plate 3d is greater than or equal to the length of the positive plate and the negative plate, the width of the receiving plate 3d is consistent with the positive plate and the negative plate, and side limit plates 3d3 are provided on both sides of the bottom plate of the receiving plate 3d. The side limit plates 3d3 are used to limit the positive and negative plates entering the receiving plate 3d.

[0056] Based on the above embodiments, the technical problem that this application wants to solve is how to ensure the stacking effect of the material receiving plate 3d on the electrode plate. To this end, this application sets the material receiving plate 3d to a width that matches the electrode plate, and provides side limit plates 3d3 on both sides of the material receiving plate 3d to limit the left and right sides of the electrode plate to prevent the electrode plate from falling.

[0057] Further, such as Figure 8 As shown:

[0058] A material moving mechanism 4 for moving the stacked pole groups of the material receiving mechanism 3 is arranged below the material discharge channel 2, and the material moving mechanism 4 includes a third linear drive device 4a arranged horizontally, and a first rotary drive device 4b is fixedly installed on the working end of the third linear drive device 4a, and a finger cylinder 4c is fixedly installed on the working end of the first rotary drive device 4b, and the working end of the finger cylinder 4c is arranged toward the opening side of the material receiving plate 3d of the material receiving mechanism 3, and a splint 4d is fixedly installed on the working end of the finger cylinder 4c, and the finger cylinder 4c drives the splint 4d to make relative movement in the vertical direction.

[0059] Based on the above embodiments, the technical problem that the present application wants to solve is how to unload the pole groups stacked on the receiving plate 3d. To this end, the present application sets a material moving mechanism 4 below the unloading channel 2, and the material moving mechanism 4 is composed of a third linear drive device 4a, a first rotary drive device 4b and a finger cylinder 4c. The working end of the finger cylinder 4c is set up and down to drive the clamping plate 4d to expand, and the third linear drive device 4a drives the clamping plate 4d to move to the opening side of the receiving plate 3d that has been rotated to a horizontal state, and the finger cylinder 4c drives the clamping plate 4d to grab the pole group, and the third linear drive device 4a drives the pole group to move to the other side to empty the receiving plate 3d, so as to facilitate the assembly of the next pole group on the receiving plate 3d, and the first rotary drive device 4b on the third linear drive device 4a drives the working end of the finger cylinder 4c to rotate 180 degrees, and cooperates with the finger cylinder 4c to place the pole group on the pole group conveying device for the next packaging process.

[0060] Further, such as Figures 6 to 8 As shown:

[0062] Based on the above embodiments, the technical problem that the present application intends to solve is how to ensure the clamping area of ​​the clamping plate 4d on the electrode group on the connecting plate 3d. To this end, the present application facilitates the clamping of the electrode group by the clamping plate 4d by providing a first slot 3d4 that matches the shape of the clamping plate 4d on the opening side of the connecting plate 3d. In the present embodiment, the first slot 3d4 is provided between the positive and negative pole ears of the electrode group, and the clamping plate 4d clamps the middle part of the electrode group. In other embodiments, the first slot 3d4 can also be provided on both sides of the pole ear, so as to facilitate the clamping plate 4d to avoid the pole ear part when clamping.

[0063] Further, such as Fig. 9 and 10 As shown:

[0064] A parallel second slide rail 4d1 is provided on the opposite side of the two splints 4d installed at the working end of the finger cylinder 4c, and a second slider 4d2 is slidably installed in the second slide rail 4d1.

The second spring 4d6 is sleeved on the second guide sleeve 4d4, and the second spring 4d6 elastically connects the splint 4d and the second slider 4d2.

[0065] Based on the above embodiments, the technical problem that this application wants to solve is how to ensure the neatness of the pole group when the clamp 4d clamps the pole group while avoiding damage to the electrode plate. To this end, this application sets a sliding second slider 4d2 on the opposite side of the two clamps 4d at the working end of the finger cylinder 4c, and the elastic cloth 4d3 is connected between the second sliders 4d2. When the third linear drive device 4a drives the clamp 4d to move toward the pole group, the elastic cloth 4d3 contacts one side of the pole group and presses the pole group on one side of the receiving plate 3d to keep the pole group neat. The elastic cloth 4d3 has a certain elasticity, and the second slider 4d2 on which the elastic cloth 4d3 is installed provides a certain buffer through the elastic connection of the second spring 4d6, so that the clamp 4d grabs the electrode plate to provide a certain buffer to protect the pole group.

Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
