[0002] With the development of new energy vehicles and drone technology, large-scale lithium battery module assembly has replaced manual work with automated assembly. Automated assembly can improve production efficiency and quality control. However, the existing loading mechanism for cylindrical lithium battery modules is difficult to ensure the distance between lithium battery modules. It is difficult to ensure consistency in subsequent assembly and changes in the center spacing between modules. There will be deviations. Only by slowing down the loading and subsequent assembly speeds can the consistency and yield of the products be guaranteed. The automation efficiency is not high. Summary of the invention

[0061] The rack electric control box 6 has the above-mentioned mechanism integrated on the upper surface and an electric control system integrated inside.

[0062] like Figure 2 The figure shows a three-dimensional structure diagram of the inclined track feeding mechanism 1, which includes a battery box 1.1, a battery removal assembly 1.2, a photoelectric sensor 1.3, an inclined track 1.4, a clamping assembly 1.5, a front and rear proximity sensor assembly 1.6, a yield assembly 1.7, an anti-stacking assembly 1.8 and a lifting assembly 1.9. As shown in the figure, the front end of the inclined track 1.4 is an inclined upper end, the battery box 1.1 and the battery removal assembly 1.2 are arranged on the left and right sides of the front end of the inclined track 1.4, followed by the photoelectric sensor 1.3, the front and rear proximity sensors 1.6 and the anti-stacking assembly 1.8 are arranged on the left and right sides of the rear end of the inclined track 1.4, the clamping assembly 1.5 is arranged at the front end of the front proximity sensor 1.6, the lifting assembly 1.9 is arranged at the lower part of the rear end of the inclined track 1.4, and the yield assembly 1.7 is arranged at the tail end of the inclined track 1.4.

[0063] The battery box 1.1 is used to load the scattered batteries required by the system. The front end of the battery taking assembly 1.2 is provided with a number of strong magnets, which are driven by a cylinder to move forward and backward, extend forward to absorb the batteries in the battery box 1.1, and retract backward to carry the absorbed batteries to the inclined track 1.4 for self-rolling transmission; the front and rear proximity sensors 1.6 are used to detect whether there are batteries transmitted from the inclined track 1.4; the make way assembly 1.7 is driven by a cylinder to extend and retract, and retract to make room for the subsequent material taking mechanism 2 to take materials; the front end of the anti-stacking assembly 1.8 is provided with a baffle, which is driven by a cylinder to move forward and backward, and extends forward to block the inclined track A plurality of battery stacks conveyed from the inclined track 1.4 are placed above the rear end of 1.4, and are retracted backwards and away from the top of the inclined track 1.4 to make room for the subsequent material-grabbing mechanism 2 to graze the materials; the lifting component 1.9 is used to lift the aforementioned plurality of batteries conveyed from the inclined state in the inclined track, convert them into a horizontal placement state, and wait for the material-grabbing mechanism 2 to come and graze the materials. An equidistant battery slot support plate is provided on the upper end of the lifting component 1.9, which is driven up and down by a cylinder. The battery slot support plate is extended upwards to automatically place the batteries in the slots at the rear end of the inclined track 1.4 into the corresponding battery slots in the support plate, and is retracted downwards and hidden in the lower part of the rear end of the inclined track 1.4.

[0064] The working process of the inclined track feeding mechanism 1 is as follows: the strong magnet at the front end of the battery assembly 1.2 is temporarily set to 10, the distance between the front and rear proximity sensors 1.6 is the distance of 10 batteries, the battery assembly 1.2 sucks 10 batteries from the battery box 1.1 into the inclined track 1.4 at one time, and the 10 batteries roll freely from high to low and are transferred to the rear end (lower end) of the inclined track 1.4. When the rear sensor 1.6 detects the presence of batteries, the clamping assembly 1.5 clamps the batteries subsequently transferred from the inclined track 1.4, and at the same time the giving way assembly 1.7 and the anti-stacking assembly 1.8 retract to make room, and the lifting assembly 1.4 is lifted. Component 1.9 moves upward to lift up the 10 batteries at the rear end of the inclined track 1.4 between the front and rear proximity sensors 1.6, waiting for the material picking mechanism 2 to come and pick up the materials. The battery picking component 1.2 continues to pick up the batteries into the inclined track 1.4. When the photoelectric sensor 1.3 at the rear end of the battery picking component 1.2 detects that the batteries in the inclined track 1.4 have accumulated to the position of the photoelectric sensor 1.3, the system instructs the battery picking component 1.2 to stop picking up the materials. When the batteries at the rear end of the inclined track 1.4 are taken away and there are no batteries accumulated on the inclined track sent by the photoelectric sensor 1.3, the battery picking component 1.2 continues to pick up the materials.

[0065] like Figure 3 As shown, it is a side view of the inclined track material taking mechanism 1, and the angle formed between the inclined track 1.4 and the horizontal plane is α, 5°≤α≤20°, and the specific angle is adjusted according to demand.

[0066] like Figure 4As shown, it is a three-dimensional structural diagram of the material picking mechanism 2, including a material picking servo module 2.1 and a material picking chuck 2.2. The material picking servo module 2.1 drives the material picking chuck 2.2 to move forward, backward, left and right. The material picking chuck 2.2 absorbs the 10 batteries lifted by the lifting component 1.9, and then moves to the deformation mechanism 3 through the material picking servo module 2.1. The material picking chuck 2.2 is driven by an independent cylinder to absorb each battery with an independent suction cup. At the same time, a limit sensor is set on the material picking servo module 2.1 to limit the movement range of the material picking chuck 2.2, so as to achieve accurate positioning of the material picking chuck 2.2, and accurately absorb and transport the 10 horizontal battery groups on the lifting component 1.9 to the variable distance mechanism 3.

[0067] like Figure 5 As shown, it is a three-dimensional structural diagram of the deformation mechanism 3, including a deformation cylinder 3.1, a left gripper 3.2 and a right gripper 3.3. The left gripper 3.2 and the right gripper 3.3 are symmetrical, and the left gripper 3.2 and the right gripper 3.3 are horizontally symmetrically arranged on the left and right sides of the deformation cylinder 3.1. A plurality of battery slots (tentatively 10) are arranged on the left and right grippers for placing corresponding batteries. Small magnets 3.4 are arranged in the battery slots. The material picking mechanism 2 takes out the battery pack lifted by the lifting component 1.9 at the lower end of the inclined track 1.4, and transports it to the battery slot on the left gripper 3.2 in a horizontal state. The small magnet in the battery slot attracts the battery, and the deformation cylinder 3.1 drives the left gripper 3.2 and the right gripper 3.3 to clamp in the vertical direction, thereby converting the battery from a horizontal placement state to a vertical state, waiting for the robot transport mechanism 4 to come over for transport.

[0068] like Figure 6 As shown, it is a three-dimensional structural diagram of the manipulator transport mechanism 4, including a manipulator 4.1 and a variable-pitch chuck 4.2. The manipulator 4.1 is provided with a CCD optical detection mechanism for recording the positions of the deformation mechanism 3 and the conveying mechanism 5, and guiding the manipulator 4.1 to drive the variable-pitch chuck 4.2 to move the battery pack in a vertical state in the deformation mechanism 3 to the conveying mechanism 5. During the transport process, the variable-pitch chuck 4.2 changes the center distance between adjacent batteries in the battery pack.

[0069] like Figure 7 As shown, it is a three-dimensional structural diagram of the variable-distance clamp 4.2, including multiple clamping blocks 4.21 (tentatively 10) and a variable-distance assembly 4.24. The 10 clamping blocks 4.21 clamp 10 batteries in a vertical state in the deformation mechanism 3, and the variable-distance assembly 4.24 drives the 10 clamping blocks 4.21 to move back and forth, thereby changing the center distance between adjacent batteries in the 10 batteries clamped by the 10 clamping blocks 4.21 to achieve the variable-distance process. An independent suction cup 4.22 is provided on the upper end of a single clamping block 4.21 and a separate clamping cylinder 4.23 is provided on the front side. The suction cup 4.21 adsorbs the battery, and the clamping cylinder 4.23 further clamps the adsorbed battery.

[0070] like Figure 8 and Fig. 9 As shown, it is a structural diagram of the pitch-changing assembly 4.24, including a telescopic cylinder 4.241, a step telescopic rod 4.242, a plurality of sliders 4.242 (tentatively 10) and a deformation limit plate 4.244, as shown in FIG. Fig.10 As shown, a step slider groove 4.245 is opened in the middle of the deformation limiting plate 4.244, and a plurality of slide bars 4.246 are arranged in the step slider groove 4.245. Ten slide bars 4.242 correspond to the step slider groove 4.245 to form a step slider, which is connected in the corresponding step slider groove 4.245 by sliding the slide bars 4.246 forward and backward. Each step of the step telescopic rod 4.242 is fixedly connected to the corresponding slide bar 4.243 in the step slider groove 4.245, and each slide bar 4.234 is fixedly connected to the clamping block 4.23 on the front side. The telescopic cylinder 4.241 drives the step telescopic rod 4.242 to move forward and backward, thereby driving the clamping block 4.21 to move forward and backward in the step slider groove 4.245 of the deformation limiting plate 4.244 through the slide bar 4.243, thereby changing the center distance of the battery clamped by each clamping block 4.21.

[0071] For example, the center distance of 10 batteries is changed from 18.5mm to 19.6mm, and the sliding distance of the 10 step sliders in the 10 steps of the step slider slot 4.245 is 1.1mm, thereby changing the original center distance of adjacent batteries from 18.5mm to 19.6mm. According to actual needs, different deformation limit plates 4.244 can be customized to achieve different distance changes. This distance change structure is simple, easy to maintain, and has high distance change accuracy.

[0072] like Fig.11 As shown, it is a three-dimensional structural diagram of the conveying mechanism 5, including a conveying streamline 5.1 and a carrier 5.2. After the manipulator conveying mechanism 4 conveys the 10 batteries after the distance change to the carrier 5.2 to form a battery module, the conveying streamline 5.1 will transfer the assembled carrier 5.2 to the next process.

[0073] The workflow of the entire variable-distance battery module assembly system is as follows:

[0074] A: Start the system, the inclined track feeding mechanism 1 starts to roll and transfer a number of batteries from high to low, and then the lifting component 1.9 lifts the inclined batteries in the inclined track 1.4 to a horizontal state (the number of lifted batteries is tentatively set at 10), waiting for the material taking mechanism 2 to come and take the materials;

[0075] B: The material taking mechanism 2 takes away the 10 horizontal batteries on the lifting assembly 1.9 through the material taking chuck, and moves them to the left gripper 3.2 in the horizontal state on the deformation mechanism 3;

[0076] C: The deformation cylinder 3.1 in the deformation mechanism 3 drives the left gripper 3.2 and the right gripper 3.3 to clamp in the vertical direction, thereby converting the 10 batteries in the horizontal state on the left gripper 3.2 into a vertical state;

[0077] D: The manipulator transport mechanism 4 is driven by the manipulator 4.1 to drive the variable-pitch chuck 4.2 to take away the 10 batteries in a vertical state on the deformation mechanism 3, and after the 10 batteries are transported to the carrier 5.2 on the conveying mechanism 5 to form a battery module, the conveying process of the conveying mechanism 5 is transmitted to the next process.

[0078] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
