[0043] Further, the Y-axis sliding seat 20 is installed on the X-axis sliding seat 11 through a linear guide rail and a sliding block;

[0044] The Y-axis sliding seat driving device 21 comprises a second servo motor 210 fixed on the Y-axis sliding seat 20, a second gear 211 connected with the second servo motor 210, and a second rack 212 fixed on the X-axis sliding seat 11, the second gear 211 is engaged with the second rack 212, preferably, the second gear is connected with the second servo motor through a speed reducer, in the embodiment, the Y-axis sliding seat 20 is a box structure, the bottom of the box is fixed on the X-axis sliding seat through a sliding block and a guide rail, the second rack is fixed in the middle of the X-axis sliding seat, the second rack is arranged laterally, the second servo motor is vertically installed in the inner bottom of the box, the second servo motor is connected with the second gear, and the second gear is engaged with the second rack. Since the Y-axis unit adopts high-precision gear and rack, and is driven through a servo motor and a speed reducer, high-precision control of the Y-axis unit is realized through cooperation of an absolute value encoder and a grating ruler, the absolute encoder is determined by mechanical position coding, does not need to be remembered, does not need to find a reference point, and does not need to be counted all the time, and the position can be read at any time, etc. advantages, and the grating ruler, also called a grating ruler displacement sensor, is a measurement feedback device working by using the optical principle of a grating.

The positioning accuracy of the C3 precision ball screw within the Z axis stroke range can be within ± 24 μm. Therefore, the repeat positioning accuracy of the Z axis system can be within ± 0.03 mm.

[0047] Further, the fixed platform 10, the X axis sliding seat 11 and the Y axis sliding seat 20 are provided with limit switches 4 at both ends, which can effectively reduce the risk of impact of the forklift system in unexpected situations.

[0048] In the embodiment, the fork 31 comprises a fork connecting part 310 and a fork jaw part 311.

[0049] The nut 322 for connecting with the ball screw 321 and the sliding block for connecting with the guide rail are fixed on the fork connecting part 310. The fork jaw part 311 is fixed with a positioning support block 312. The fork structure can be conveniently inserted into the zero point positioning sub-plate tool below and drive the zero point positioning sub-plate tool to move, so as to realize installation with the zero point positioning mother plate tool on the machine tool, reduce adjustment time and improve processing efficiency.

[0050] Further, the fixed platform 10 is also provided with a limit sensor group corresponding to each parking position, which includes three limit sensors fixed in sequence along the X-axis direction on the fixed platform; when the X-axis unit moves from a position away from the parking position to the parking position, when the X-axis sliding seat driving device drives the X-axis sliding seat to move through the two side limit sensors to the middle limit sensor, the X-axis sliding seat driving device drives the X-axis sliding seat to decelerate and stop at the middle limit sensor; when the X-axis unit moves from the parking position to a position away from the parking position, the X-axis sliding seat driving device drives the X-axis sliding seat to accelerate. Specifically, the controller obtains the real-time motion speed and real-time position of the motion mechanism (X-axis sliding seat) according to the encoder of the servo motor and other sensor units, and judges whether the current X-axis unit is moving towards the parking position or away from the parking position according to the real-time position; when the X-axis unit moves from a position away from the parking position to the parking position, when the X-axis sliding seat driving device drives the X-axis sliding seat to move through the two side limit sensors to the middle limit sensor, the X-axis sliding seat driving device drives the X-axis sliding seat to decelerate and stop at the middle limit sensor; when the X-axis unit moves from the parking position to a position away from the parking position, the X-axis sliding seat driving device drives the X-axis sliding seat to accelerate until its motion speed reaches a defined speed, and then maintains its uniform motion. Due to the arrangement of the limit sensor group, the present application can realize acceleration and deceleration during movement, the running speed gradually slows down in the linear deceleration section, the impact on the motion mechanism caused by sudden speed reduction is reduced, the running is more stable, not only avoids the need for the motion mechanism to perform a long distance low-speed running, ensures the running efficiency of the forklift, but also through step-by-step speed reduction, the motion mechanism can be limited to a micro-speed state before reaching the preset stopping point, which can avoid impact on the forklift even if it stops immediately, and precise parking is achieved at the limit point. That is, in order to improve the efficiency of zero-point positioning sub-plate tooling, the X-axis unit is provided with an acceleration stage, a deceleration stage and a precise control stage during movement, a plurality of limit sensors are arranged on the X-axis track, and the three stages of acceleration, deceleration and precise control are passed before running to the specified position. The overall weight of the forklift is about 5t, and the running load is 2.5t. Due to the heavy weight, a large inertia is generated during high-speed movement. In order to better control the accuracy of the forklift, the movement process is divided into three stages, the inertia affecting the accuracy is reduced through acceleration and deceleration, and finally the final positioning of the forklift is realized through precise control.

[0051] Further, the controller can also electrically soft limit the X-axis unit: the soft limit is the movement range limit value set in the software. According to the kinematics principle of the forklift, the forklift can accurately reach a position in space, which relies on the movement of each axis from zero to a specific position, thereby synthesizing the final position. The soft limit (corresponding to the hard limit) can set the active range in the positive and negative directions, so that when the forklift moves and detects that it has exceeded the range, the controller stops the forklift and pops up the corresponding error information to prompt the over-limit. The soft limit should be smaller than the mechanical limit, so that when the soft limit fails, the hard limit can continue to function.

[0052] The Y-axis and the Z-axis are both used with absolute value encoders and grating rulers. Due to the short running stroke, high-precision control can be achieved through running acceleration and deceleration.

[0053] Further, the fork jaw part 311 is also fixed with an RFID read-write head mounting interface 313 for identifying workpiece tray information. At the same time, the fork with tray has a detection function, which avoids the risk of equipment impact caused by the loss of PLC information memory due to power failure and re-powering.

[0054] Further, two guide rails are arranged on the table surface of the fixed platform 10, and one guide rail is arranged on the side of the fixed platform opposite to the first rack, so as to ensure the stability of operation.

[0055] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto.
