Figure 8 As shown, the guide hopper 9 is provided to facilitate the delivery of raw materials required for the battery to the material feeding frame 10, and the battery raw materials are guided through the guide trough 11; the baffle 12 and the top of the material feeding frame 10 are both provided 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 setting of the gathering bucket 13 facilitates the gathering of battery raw materials from the material guide hopper 9, ensuring the accuracy of battery raw materials when they are discharged; One end of the base 1 is provided with a first electric push rod 14 for driving the displacement of the slide 2, and the outer side of the slide 2 is slidably connected to a connecting frame 15, and the connecting frame 15 is provided with a second electric push rod 16 for driving the displacement of the limit sleeve 5. Figure 4 As shown, the first electric push rod 14 drives the slide plate 2 to move so that the slide plate 2 moves to the bottom of the unloading frame 10, so that the material in the guide trough 11 can fall into the battery cell placed on the supporting rod 3, and the second electric push rod 16 drives the connection frame 4 and the limiting sleeve 5 to move so as to adjust the position of the connection frame 4 and the limiting sleeve 5.

The two discharge ports 17 are slidably connected with a blocking block 18. A third electric push rod 19 is provided on one side of the guide hopper 9 for driving the blocking block 18 to move up and down. Figure 8 As shown, the material in the guide hopper 9 is discharged through the discharge port 17, and the stop block 18 is driven to move by the third electric push rod 19 to adjust the opening size of the discharge port 17, and then adjust the flow rate of the material discharge; A reinforcement frame 20 is provided on one side of the base 1, a fourth electric push rod 21 is provided on the top of the reinforcement frame 20, and a pressure head 22 is provided at the output end of the fourth electric push rod 21. Figure 1 、 2 As shown in Figure 6, the fourth electric push rod 21 drives the pressure head 22 to move downward, so that when the pressure head 22 contacts the battery shell, the battery shell and the battery cell are connected together; a fifth electric push rod 23 is provided on the top of the inner cavity of the reinforcement 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 push 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 to drive the extension plate 25 and the push plate 26 to move, so that the push plate 26 can resist the outside of the assembled battery shell, making it convenient to push out the assembled battery; a side plate 28 is provided on one side of the horizontal plate 24, and the side plate 28 is mounted on one side of the inner wall of the reinforcement frame 20 by bolts, and a long waist hole 29 is opened through the side plate 28, the top of the inner cavity of the long waist hole 29 is vertically downward, and a pulley installed on one side of the extension plate 25 is slidably connected in the long waist hole 29, as shown in the attached figure. Figure 6 As shown, when the horizontal plate 24 moves up and down, the pulley rubs against the long waist hole 29. When the pulley is located in the vertical long waist hole 29, the pulley is forced to push the extension plate 25 and the push plate 26 to move laterally along the guide of the horizontal plate 24, so that the push plate 26 can be easily pressed against the assembled batteries. When the horizontal plate 24 moves upward, the pulley moves into the inclined long waist hole 29 to facilitate the reset of the extension plate 25 and the push plate 26. A guide plate 30 is provided on one side of the top of the side plate 28, and the guide plate 30 extends to the bottom of the pressure head 22. Figure 6 As shown, the guide plate 30 is used to guide the displacement of the pressure head 22 to ensure the stability of the pressure head 22 during displacement; a guide bucket 31 is provided on one side of the base 1, and one end of the guide bucket 31 is tilted downward, as shown in the attached Figure 1 As shown, the channeling bucket 31 is provided to channel the assembled batteries.

[0019] The specific working principle is as follows: battery raw materials, such as positive electrode materials, diaphragms, etc. are put into the guide hopper 9, as shown in the attached Figure 5 、 8 As shown in the figure, the third electric push rod 19 drives the blocking 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 bucket 13 through the discharge port 17, is gathered by the gathering bucket 13, and then enters the guide chute 11 of the discharge frame 10. The guide chute 11 guides the raw material to the bottom of the discharge frame 10, completing the precise delivery of the raw material.

[0020] Place the battery cell on the top of the supporting rod 3, as shown in the attached Figure 7The first electric push rod 14 is activated, driving the slide plate 2 to slide along the top of the base 1 until the support rod 3 moves to the position directly below the unloading frame 10. At this time, the raw materials in the guide trough 11 fall along the trough body into the battery cells on the support rod 3, completing the raw material loading of the battery cells.

[0021] Place the battery shell in the limiting sleeve 5, as shown in the attached Figure 7 The second electric push rod 16 drives the connecting frame 4 to move, as shown in the attached Figure 2 and 4 As shown, until the offset opening 27 at the bottom of the connecting frame 4 corresponds to the position of the supporting rod 3, the battery shell in the limiting sleeve 5 and the battery cell on the supporting rod 3 remain coaxially aligned, preparing for subsequent assembly.

[0022] The first electric push rod 14 drives the slide plate 2 to move again, and moves the aligned battery cell and housing to the bottom of the pressure head 22, as shown in the attached figure. Figure 1 、 6 The fourth electric push rod 21 is started, driving the pressure head 22 to move vertically downward along the guide plate 30, as shown in the attached Figure 6 As shown, the pressure head 22 contacts the top of the battery shell and applies pressure to make the shell and the battery core fit tightly together; in this process, the supporting rod 3 slides downward along the slide plate 2 under pressure, and its bottom end presses the top plate 8, compressing the spring 7 in the positioning cylinder 6, as shown in the attached figure. Figure 7 After assembly is completed, 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, thereby driving the supporting rod 3 to move upward, ejecting the assembled battery to the initial height, completing automatic demoulding.

[0023] The fifth electric push rod 23 is started to drive the horizontal plate 24 to move downward. Figure 3 、 6 As shown. The horizontal plate 24 drives the extension plate 25 to move downward synchronously. The pulley on one side of the extension plate 25 slides along the long waist hole 29 of the side vertical plate 28. The vertical section of the long waist hole 29 guides the pulley to move horizontally, causing the extension plate 25 to slide along the horizontal plate 24 toward the battery, thereby pushing the push plate 26 to contact the assembled battery; the push plate 26 pushes the battery to the guide bucket 31 on the side of the base 1. The battery slides out along the inclined guide bucket 31, completing the automatic output of the finished product. Subsequently, the fifth electric push rod 23 drives the horizontal plate 24 to move upward and reset. The pulley slides along the inclined section of the long waist hole 29, driving the extension plate 25 and push plate 26 to reset, waiting for the next assembly cycle.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
