DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, the new type of grinding machine includes a bed 1 and a grinding wheel 2 arranged in the bed 1, a chuck 3 for clamping a workpiece 18 and a working box 4 for installing the chuck 3, an automatic loading device is arranged outside the bed 1, and the automatic loading device includes a base plate 5 and manipulator robots arranged on both sides of the base plate 5, and a positioning mechanism is arranged on the base plate 5 between the two manipulator robots.

[0020] Preferably, the two manipulator robots are a loading robot 6 and a feeding robot 7 respectively.

[0021] To elaborate further, a driving device for controlling the cross movement of the working box 4 is provided in the bed 1. The working box 4 has a bottom plate at the bottom, and a transmission screw is installed at the bottom of the bottom plate. A driving device is installed at the bottom of the bed 1 to control the transmission of the transmission screw and drive the bottom plate and the working box 4 on the bottom plate to move linearly. In addition, a driving device is also installed at the rear end of the working box 4, that is, the top of the bottom plate, and the linear movement of the working box 4 is also controlled by the transmission screw. The direction of the linear movement is in a cross direction with the direction of the above-mentioned linear movement.

[0022] To further elaborate, the positioning mechanism includes a bottom box and a positioning seat 8 installed on the top of the bottom box. The workpiece 18 is placed in the positioning seat 8 by the loading robot 6. Two clamping assemblies are symmetrically arranged on the positioning seat 8. The positioning seat 8 has a mounting tube 9 for mounting the clamping assembly; the clamping assembly includes a long rod 10, a small rotary cylinder 11 and a clamping portion 12 installed at the front end of the long rod 10, and a small cylinder 13 installed at the rear end of the long rod 10. The small rotary cylinder 11 and the clamping portion 12 are an integral structure or connected by a flange. The flange connection can be disassembled and can be switched according to different specifications of the shaft rod. The long rod 10 is slidably installed in the mounting tube 9, and a supporting slip ring is provided between the long rod 10 and the mounting tube 9 to prevent Wear occurs between the stop rod 10 and the mounting tube 9; the clamping part 12 is an arc-shaped structure, which is connected to the shaft rod, and the clamping parts 12 on both sides can stably clamp the shaft rod; monitoring holes are opened on the two clamping parts 12, and sensors 14 are installed in the monitoring holes. After the workpiece 18 is clamped by the clamping part 12, the two sensors 14 sense the straight-line distance between the two opposite sides of the workpiece 18. The value of the straight-line distance is identified by the PLC programming system before the grinding machine processing. If it is lower than the value and the range of the value, it is judged to be the other end of the workpiece 18, indicating that the direction in which the loading robot 6 clamps the workpiece 18 into the positioning seat 8 is opposite, then the small rotary cylinder 11 works to drive the clamping part 12 to rotate, so that the workpiece 18 turns over.

[0023] Preferably, a linear guide rail 15 is provided on the base plate 5 , and a line plate 16 for driving the two manipulator robots to move is installed on the top of the linear guide rail 15 , and driving mechanisms 17 for controlling the movement of the two manipulator robots are provided at both ends of the base plate 5 .

[0024] Preferably, a loading tray is disposed outside the substrate 5 and is docked with the loading robot 6 .

[0025] The loading robot 6 will grab the workpiece 18 from the loading tray and place it on the positioning seat 8 and clamp it by the two clamping parts 12 (under the action of the small cylinder 13). If the workpiece 18 is placed correctly, there is no need to flip it. Otherwise, it will be flipped and then sent to the chuck 3 in the grinder by the feeding robot 7.

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
