[0015] Working principle of the present application:

[0016] The auxiliary feeding device for the plate edge sealing machine is matched with the plate edge sealing machine, the feeding mechanism feeds the plate edge sealing machine, the turnover mechanism is used for rotating the plate, and the conveying belt is used for conveying the plate.

[0017] The first horizontal and vertical moving assembly of the feeding mechanism drives the first supporting seat to move horizontally and vertically, the first rotating table and the first clamping assembly move horizontally and vertically with the first supporting seat, the first clamping assembly approaches or moves away from the edge sealing machine along the vertical direction and adjusts the relative position with the edge sealing machine along the horizontal direction; the camera of the feeding mechanism is used for identifying the positional relationship among the first clamping assembly, the edge sealing machine and the plate; after the first clamping assembly clamps the unsealed blank plate, the first clamping assembly approaches the edge sealing machine for feeding, according to the position of the working edge of the plate identified by the camera, the controller receives and sends signals to adjust the horizontal relative position with the edge sealing machine, so that the working edge of the plate faces the edge sealing working port of the edge sealing machine, after the limit sensor on the conveying belt detects the plate and the edge sealing machine holds the plate, the controller receives and sends signals to control the first clamping assembly to release the mechanical clamps in turn from near to far, so as to feed the edge sealing machine; the first rotating table can drive the first clamping assembly to rotate, adjust the clamping angle of the first clamping assembly, and adapt to plates of different shapes.

[0018] The second transverse and longitudinal moving assembly of the turnover mechanism drives the second support base to move transversely and longitudinally, and the second rotating table moves transversely and longitudinally together with the second clamping assembly, so that the second clamping assembly is adjusted to be close to or away from the edge banding machine in the longitudinal direction and is adjusted to be transversely relative to the edge banding machine; after the edge banding machine completes the edge banding of one edge of the plate, the camera of the turnover mechanism identifies the positional relationship among the second clamping assembly, the edge banding machine and the plate; the controller controls the second clamping assembly to adjust the position through the second transverse and longitudinal moving assembly, so as to catch and clamp the plate from the discharge end of the edge banding machine; for a long strip-shaped plate with a longitudinal length much greater than a transverse width, in order to save the rotating space, the controller controls the lifting mechanism to lift up one end of the second rotating table, and after the second rotating table is rotated to an inclined angle around the fixed rotating shaft through the rotating shaft support base, the controller controls the second rotating table to rotate the second clamping assembly by a certain angle, for example, 90° or 180° for a regular rectangular plate, so that one edge of the plate which has not been edge banded corresponds to the edge banding machine, and then the controller controls the second transverse and longitudinal moving assembly to drive the second support base to approach the edge banding machine, but the plate is kept a certain distance from the edge banding operation area of the edge banding machine, and the plate is sent to the transmission belt, and after the limiting sensor on the transmission belt detects the plate, the controller controls the second clamping assembly to gradually loosen the mechanical clamping jaw from near to far, and the plate is conveyed back to the feeding mechanism through the transmission belt, the feeding mechanism identifies the position of the plate through the camera and adjusts the position of the first clamping assembly through the controller to catch and clamp the plate, and after the position between the plate and the edge banding machine is adjusted, the above steps are repeated to feed the plate again.

[0019] The first X-axis sliding assembly of the first transverse and longitudinal moving assembly drives the first Y-axis sliding assembly to slide along the X-axis (transversely), and the first Y-axis sliding assembly drives the first support base to slide along the Y-axis (longitudinally).

[0020] Similarly, the second X-axis sliding assembly of the second transverse and longitudinal moving assembly drives the second Y-axis sliding assembly to slide along the X-axis (transversely), and the second Y-axis sliding assembly drives the second support base to slide along the Y-axis (longitudinally).

[0021] The first rotating table support of the first rotating table plays a role of a supporting and connecting platform, the first stepper motor drives the outer ring of the first rotating disc bearing to rotate around the inner ring through the first driving gear output torque, so as to drive the first clamping assembly to rotate, thereby facilitating the first clamping assembly to adjust the clamping angle.

[0022] Similarly, the second rotating table support of the second rotating table plays a role of a supporting and connecting platform, the second stepper motor drives the outer ring of the second rotating disc bearing to rotate around the inner ring through the second driving gear output torque, so as to drive the second clamping assembly to rotate, thereby facilitating the second clamping assembly to adjust the clamping angle.

[0023] The support seat shell of the second support seat plays a supporting and connecting role, a part of the upper table surface of the support seat shell is a plane, providing support force for the second clamping assembly, and another part is an inclined surface, providing inclined space for the rotation of the plate of the second clamping assembly; the rotating shaft support seat installation groove at the joint of the plane and the inclined surface of the upper table surface of the support seat shell provides space for the rotating shaft support seat, so that the rotating shaft support seat can be flush with the plane of the upper table surface of the support seat shell and flush with the inclined surface of the upper table surface of the support seat shell.

[0024] The lifting cylinder of the lifting mechanism rotates the second rotating table around the fixed rotating shaft of the rotating shaft support seat through the jacking force and through the rotating table connecting head.

[0025] The X-axis ball screw module of the first clamping assembly drives the two Y-axis ball screw modules to move in the same direction or in the opposite direction through the bidirectional ball screws; the Y-axis ball screw module drives the two jaw sliding seats on it to move in the same direction or in the opposite direction through the bidirectional ball screws; the four jaw sliding seats can be simultaneously opened outward or contracted inward, thereby adjusting the clamping range; the movement mode of the second clamping assembly is the same as that of the first clamping assembly.

[0026] The beneficial effects of the present application are as follows:

[0027] The auxiliary feeding device for the plate edge banding machine provided by the present application can greatly improve the degree of automation, save a large amount of manpower for large-scale plate processing plants, and improve the plate edge banding work efficiency. In addition, when processing a long plate, the innovative inclined rotation method can realize the rotation of the plate without a large space, thereby solving the problem of limited space of the plate processing plant.
