[0045] Reference below Figure 1-Figure 8 The stacking table unloading mechanism 100 according to the embodiment of the present utility model is described.

[0046] like Figure 1 and Figure 2 As shown, the stacking platform unloading mechanism 100 according to the embodiment of the utility model includes a base 1, a stacking platform assembly 2, a transfer platform assembly 3 and a handling assembly 4.

[0047] Specifically, Figure 1 and Figure 2 As shown, combined Figure 2 and Figure 3, the stacking table assembly 2 is arranged on the base 1, and is used to place the stacking sheets, ensuring the operation of the stacking table unloading mechanism 100 and the function of receiving the unloading. The robot can place the stacking sheets on the stacking table assembly 2 for stacking, such as placing the pole pieces on the stacking table assembly 2 and continuously stacking them to form a pole group. The transfer table assembly 3 is arranged on the base 1 and is movable along the first direction on the base 1, and is used to transfer the received stacking sheets to the next section, ensuring the operation and transfer function of the stacking table unloading mechanism 100 and improving the flexibility. After receiving the pole group formed by the stacking of pole pieces, the transfer table assembly 3 can move along the first direction, and transport the transported pole group to the next section for hot pressing. Among them, the transfer table assembly 3 can be connected to the base 1 by means of a gear rack. For example, the base 1 can be provided with a guide rail 110 and a rack extending along a first direction, the transfer platform assembly 3 can be connected to a transfer drive motor 11, the output shaft of the transfer drive motor 11 is connected to a transfer gear 111, and the transfer gear 111 cooperates with the rack of the base 1. When the transfer drive motor 11 is energized, the output shaft can be driven to drive the transfer gear 111 to rotate clockwise or counterclockwise, thereby realizing the movement of the transfer platform assembly 3 on the base 1 along the first direction.

[0048] Preferably, if Figure 1 and Figure 2 As shown, the base 1 may be provided with a lifting platform 120 to facilitate the passage of the transfer platform assembly 3. The stacking platform assembly 2 is arranged on the lifting platform 120 of the base 1, and the transfer platform assembly 3 can pass through the lifting platform 120 and pass under the stacking platform assembly 2 when moving along the first direction, so as to avoid collision between the components and ensure the normal operation of the stacking platform unloading mechanism 100.

[0049] Furthermore, if Figure 1 and Figure 2 As shown, the transport assembly 4 is arranged on the base 1 and can move along the first direction and the up-down direction on the base 1, and the first direction is perpendicular to the up-down direction. The transport assembly 4 is used to transport the stack on the stack assembly 2 to the transfer platform assembly 3 to complete the transport function of the stack unloading mechanism 100, so as to facilitate the subsequent transfer platform assembly 3 to transport the stack, ensure the smooth operation of the stack unloading mechanism 100, realize the unloading operation, and improve the stability. For example, after the robot places the stack on the stack assembly 2 to complete the stacking, the transport assembly 4 can move along the first direction on the base 1 toward the direction close to the stack assembly 2 and adjust to a suitable position in the up-down direction. After the stacked stack on the stack assembly 2 is clamped, the transport assembly 4 will move along the first direction toward the direction away from the stack assembly 2 and move downward to the transfer platform assembly 3, and then put the clamped stack on the transfer platform assembly 3, thereby completing the transport of the stack.

[0050] Among them, the stacking platform unloading mechanism 100 can be provided with a first drive assembly and a second drive assembly 6, the first drive assembly is used to drive the second drive assembly 6 to move along the first direction on the base 1, the conveying assembly 4 can be connected to the second drive assembly 6, and the second drive assembly 6 is used to drive the conveying assembly 4 to move in the up and down direction.

When the first drive assembly is powered on, the first drive motor transmits power and torque through the first coupling to drive the first screw to rotate, and the first nut will rotate accordingly, thereby driving the second drive assembly 6 and the conveying assembly 4 to move along the first direction together. For another example, the second drive assembly 6 includes a second drive motor, which may be a ball screw motor, and the second drive assembly 6 also includes a second coupling, a second screw rod and a second nut, wherein the second screw rod is connected to the second drive motor through the second coupling, and the second screw rod extends in the up-down direction and is rotatably connected to the second nut.

Further, the clamping member 42 includes a first clamping member 421 and a second clamping member 422, and the first clamping member 421 and the second clamping member 422 are movably arranged on the fixing member 41 along the first direction, and the fixing member 41 extends along the first direction. The first clamping member 421 and the second clamping member 422 are connected to the fixing member 41 through the transport cylinder 15, and the transport cylinder 15 is preferably a finger cylinder, and the first clamping member 421 and the second clamping member 422 are respectively connected to the two claws of the finger cylinder, and the two claws of the finger cylinder can drive the first clamping member 421 and the second clamping member 422 to move closer or farther from each other by controlling the change of air pressure, so as to realize the function of the transport assembly 4 to pick up or put down the stacking sheet. The lower ends of the first clamping jaw 421 and the second clamping jaw 422 have hook claws 424 extending toward each other, which makes it easier for the clamping jaw assembly 42 to pick up the stack.
