In the currently commonly used plate packing machine, after the positive polar plates and the negative polar plates are placed on the conveying line, the push plate is pushed forward to form a polar plate group, and after the push plate is returned to the initial position after pushing a polar plate, another polar plate can be placed, otherwise, the placed polar plate will be pushed out of the conveying line during the backward movement of the push plate. Therefore, it takes a long time and the efficiency is low. SUMMARY

[0004] The utility model discloses a technical means that is adopted for solving the above problem: a feeding mechanism capable of continuously feeding polar plates, which comprises a placing table for placing polar plates, a feeding device for transferring the polar plates to the placing table, a push plate device for pushing the polar plates forward, and a telescopic device for avoiding the interference between the push plate device and the polar plates on the placing table during the resetting process of the push plate device, wherein the telescopic device and the push plate device are both arranged below the placing table, and the telescopic device is located at the side of the push plate device; wherein the push plate device comprises a push rod capable of rotating at one end and used for pushing the polar plates, and a resetting device used for resetting the rotated push rod, and the telescopic device comprises a telescopic block used for tilting the one end of the push rod to rotate forward when the push rod is returned. After the push rod rotates at one end, the overall height is lowered, and the polar plates to be pushed forward on the placing table are not interfered.

[0005] Further, the push plate device further comprises a push rod moving in a straight line under the power, the push rod is rotationally connected with the push rod at one end, and the push rod can only tilt and rotate forward or return to the upright state, one end of the resetting device is fixed to the push rod, and the other end is fixed to the push rod.

[0006] Further, the resetting device comprises a push-pull spring connected with the push rod and the push rod at both ends.

[0007] Further, the resetting device further comprises two fixed pins arranged on the push rod and the push rod respectively, and the two ends of the push-pull spring are connected with the two fixed pins respectively.

[0008] Furthermore, the telescopic device includes a fixed block and a telescopic block rotatably connected at one end, and a telescopic spring is provided between the other ends of the fixed block and the telescopic block. The two ends of the telescopic spring are respectively connected to the fixed block and the telescopic block, and the telescopic block is located on the side closer to the push plate device. The telescopic spring neither hinders the telescopic block from retracting nor prevents the telescopic block from returning to its original position.

[0009] Furthermore, the connection between the fixed block and the telescopic block is located near the initial end of the push plate device, while the telescopic spring is located near the end of the push plate device in the forward direction.

[0010] Furthermore, the end face of the telescopic block at the initial end of the push plate device is an inclined plane that slopes in the forward direction, while the end face of the telescopic block at one end of the push plate device in the forward direction is a straight plane that is perpendicular to the forward direction of the push plate device; the side of the lever near the telescopic device is provided with a stop block that contacts the inclined plane or the straight plane.

[0011] Furthermore, a gap is provided in the middle of the placement platform, and the two ends of the electrode plate overlap at the two ends of the gap, and the pusher device reciprocates along the gap.

[0012] Furthermore, the feeding mechanism also includes a guide plate located below the placement platform.

[0014] Furthermore, the end of the lever away from its connection with the push rod is provided with a Y-shaped fork with an opening facing the forward direction. The electrode plate is pushed forward by the fork.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model designs the lever of the push plate device to be rotatable at one end, and sets a telescopic device to guide and limit the state of the lever, so that the lever rotates during the return process of the push plate device, thereby preventing the lever from pushing the electrode plate out of the placement platform.

[0017] 2. This utility model sets fixing pins on the push rod and the lever respectively, and connects the two fixing pins with a spring, so that the lever can rotate along the connection when subjected to external force, and can return to its original position under the pull of the spring after the external force is removed.

[0018] 3. This utility model uses telescopic blocks with inclined surfaces and straight surfaces at both ends. When the pusher moves forward, the stop block pushes the inclined surface of the telescopic block, causing the telescopic block to retract without affecting the movement of the pusher. When the pusher moves backward, the stop block pushes the straight surface of the telescopic block, preventing the telescopic block from retracting and forcing the free end of the lever to rotate downward, reducing the height of the pusher and preventing the basic structure of the placement platform from being pushed out.

[0019] 4. This utility model completes the rotation and limit of the push plate device when it returns by cooperating with the guide plate and guide wheel, and cooperating with the telescopic device and the stop block. This can reduce the length of the telescopic device and make the entire mechanism more stable. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only, representing schematic diagrams only, not actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0030] A feeding mechanism for continuously feeding electrode plates, such as Figure 1 As shown, the device includes a feeding device 1, a placement platform 2, a guide plate 3, a telescopic device 4, and a pusher device 5. In this embodiment, there are two sets of each of the feeding device 1, placement platform 2, telescopic device 4, and pusher device 5, all sharing a single guide plate 3. The two placement platforms 2 are arranged parallel to each other above the guide plate 3, with the guide plate 3 located in the middle below the two placement platforms 2. One feeding device 1 is positioned above one placement platform 2, one pusher device 5 is positioned in the middle below one placement platform 2, and one telescopic device 4 is positioned on the side below one placement platform 2 away from the guide plate 3. Two sets of structures for placing the electrode plates 6 and pushing the electrode plates 6 forward are provided on both sides of the guide plate 3, making the entire feeding mechanism more compact and saving space. The feeding device 1 can adopt a currently common structure, such as a suction cup at the bottom, which, driven by a cylinder, adsorbs the electrode plates 6 onto the placement platform 2; details will not be elaborated here. The placement platform 2 has a structure with a gap in the middle, with the electrode plates 6 overlapping on both sides of the gap. The pusher device 5 moves back and forth along the gap to push the electrode plates 6 forward.

[0031] like Figure 3 As shown, the telescopic device 4 and the guide plate 3 are located on both sides of the push plate device 5, and the length of the telescopic device 4 and the guide plate 3 along the movement direction of the push plate device 5 is less than the distance the electrode plate 6 moves forward. This ensures that when the push plate device 5 pushes the electrode plate 6 into place, neither the telescopic device 4 nor the guide plate 3 will exert any force on the push plate device 5, thus not affecting the state of the push plate device 5.

[0032] like Figure 9As shown, the pusher device 5 includes a push rod 51 that is driven to move linearly by a power source, a lever 52 that is driven to move linearly by the push rod 51, and a reset device for resetting the lever 52. The push rod 51 and the lever 52 are rotatably connected at one end. In the initial state, the push rod 51 and the lever 52 are approximately perpendicular. Under external force, the lever 52 can rotate along one end of the push rod 51. When the lever 52 rotates, it can only rotate forward or return while in an upright position. Therefore, when the push rod 51 drives the lever 52 to push the electrode plate 6 forward, it can maintain an upright position to ensure the electrode plate 6 moves forward; when the push rod 51 drives the lever 52 back, the lever 52 can move downward, reducing its height. The reset device includes two fixing pins 56 and a push-pull spring 55. The two fixing pins 56 are respectively mounted on the push rod 51 and the lever 52. The two ends of the push-pull spring 55 are respectively connected to the push rod 51 and the lever 52. The fixing pins 56 can be screwed onto the push rod 51 or the lever 52, while the two ends of the push-pull spring 55 are hooked onto the push rod 51 and the lever 52, so that the fixing pins 56 and the push-pull spring 55 can be replaced at any time. At the connection between the push rod 51 and the lever 52, the push rod 51 provides a limit to the lever 52, so that the free end of the lever 52 can only tilt forward and rotate when force is applied. When the external force is removed, the push-pull spring 55 pulls the lever 52 back to a vertical state.

[0033] like Figure 6 and Figure 7 As shown, the telescopic device 4 includes a fixed block 41 fixed relative to the placement platform 2, and a telescopic block 43 rotatably connected to the fixed block 41 at one end. The fixed block 41 and the telescopic block 43 are connected at the other end by a fixing spring 42. Under the action of external force, the telescopic block 43 compresses the fixing spring 42 and rotates relative to the fixed block 41 (e.g., ...). Figure 7 As shown), when the external force disappears, the fixed spring 42 pushes the telescopic block 43 back, causing it to rotate in the opposite direction relative to the fixed block 41 and then return to its original position. Correspondingly, as... Figure 6As shown, the lever 52 has an outwardly protruding stop 54 on its side near the telescopic device 4, while the telescopic block 43 has an inclined surface 431 oriented towards the forward direction of the push plate device 5 on its side near the initial end of the push plate device 5, and a straight surface 432 perpendicular to the forward direction of the push plate device 5 on its side near the forward end of the push plate device 5. The connection end of the telescopic block 43 and the fixed block 41 is close to the initial position of the push plate device 5, and the fixed spring 42 is located at one end of the push plate device 5 in the forward direction. Thus, when the push rod 51 drives the lever 52 to push the electrode plate 6 forward, the stop 54 touches the inclined surface 431 of the telescopic block 43, causing the telescopic block 43 to rotate without interfering with the forward movement of the lever 52. When the push rod 51 pulls the lever 52 back, the stop 54 touches the straight surface 432 of the telescopic block 43, and the telescopic block 43 cannot retract but instead holds the stop 54, forcing the lever 52 to tilt forward and rotate around the push rod 51, thus lowering the height of the lever 52. Meanwhile, in order to better drive the electrode plate 6, the free end of the lever 52 is set as a Y-shaped fork so that its shape can better match the electrode plate 6.

[0034] like Figure 5 and Figure 6 As shown, the lever 52 is provided with a guide wheel 53 on the side near the guide plate 3, that is, away from the stop block 54. The guide wheel 53 moves against the guide plate 3. When the push plate device 5 moves forward, the guide wheel 53 is above the guide plate 3, and when the push plate device 5 moves backward, the guide wheel 53 is below the guide plate 3. The guide plate 3 provides guidance and limit for the guide wheel 53.

[0035] During the work process, such as Figure 2 As shown, when the feeding device 1 delivers the electrode plate 6 to the placement table 2, the power pushes the push rod 51 forward, causing the lever 52 to push the electrode plate 6 forward along the placement table 2. At this time, the lever 52 and the push rod 51 are roughly perpendicular, and the guide wheel 53 moves forward along the upper surface of the guide plate 3. During the forward movement, as... Figure 6 As shown, the stop block 54 pushes against the inclined surface 431 of the telescopic block 43, as... Figure 7 As shown, it is retracted to avoid blocking the forward movement of lever 52.

[0036] like Figure 3 As shown, when the lever 52 pushes the electrode plate 6 forward to a certain distance, the feeding device 1 continues to send the electrode plate 6 to the placement platform 2, while the push rod 51 pulls the lever 52 to start returning.

[0037] like Figure 4 and Figure 8As shown, when the lever 52 returns to a certain distance, the stop block 54 contacts the straight surface 432 of the telescopic block 43. The telescopic block 43 pushes the stop block 54, thereby forcing the lever 52 to tilt forward and rotate, reducing the height of the lever 52. As the lever 52 continues to retract, the guide wheel 53 enters the area below the guide plate 3 and rolls along the lower surface of the guide plate 3, keeping the lever 52 in a forward tilted state so that it will not touch the electrode plate 6 on the placement platform 2.

[0038] like Figure 5 As shown, when the guide wheel 3 rolls to the edge of the guide plate 3, the lever 52 continues to move backward, the guide wheel 3 disengages from the guide plate 3 and no longer bears the downward pressure, the push-pull spring 55 pulls the lever 52 to reset it, the power changes direction, pushes the push rod 51 forward, and then makes the lever 52 push the next electrode plate 6 forward.

[0039] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the protection scope of the present invention, which should be defined by the claims.
