[0028] Specifically, when the loading motor 1 is started, it drives the front lead screw 11 to rotate. Through the cooperation of the sliding sleeve, the connecting block, the robotic arm mounting plate 17, the front lateral guide rail 9 and the front guide rail slider 7, it drives the material suction mounting plate 14 to move back and forth left and right, that is, drives the material suction module to move back and forth left and right. Similarly, when the pulling motor 2 is started, it can drive the pulling side plate 30 to move back and forth left and right, that is, drives the robotic arm base 29 together with the pulling module on its top to move back and forth left and right.
[0029] The material suction module includes a material suction cylinder. The material suction cylinder includes an upper cylinder 12 and a lower cylinder 16. The output end of the upper cylinder 12 and the output end of the lower cylinder 16 are connected through a cylinder connecting plate 21.

A workpiece protection plate 27 is sleeved on the outer side surface of the bracket connecting device 25. A suction cup assembly is provided at the bottom of the bracket connecting device 25.
[0030] Specifically, when the material suction module works: the material suction cylinder works, and with the connection and cooperation of the vertical guide rail 18, the vertical guide rail slider 19 and the lower cylinder mounting plate 15, the suction cup assembly at the bottom of the bracket connection device 25 moves vertically to pick and place workpieces.
[0031] The suction cup assembly includes a suction nozzle bracket 23. The suction nozzle bracket 23 is in an "X" shape.

When air is introduced, under the action of air pressure, the adjusting rod 44 can drive the suction nozzle 46 to move up and down relative to the suction nozzle bracket 23 for fine adjustment, ensuring that the four suction nozzles 46 are in smooth contact with the wafer and preventing the wafer from being damaged due to excessive air introduction force. The suction cup assembly is a flexible clamping manipulator.
[0032] The material pulling module includes a stepping motor 31 installed on the top surface of the lower guard plate 28 of the robot arm. The output shaft of the stepping motor 31 is connected with a main pulley. One end of the top of the robot arm base 29 is provided with a secondary pulley through a pulley mounting plate. The secondary pulley and the main pulley are connected by a synchronous belt 35 in transmission. A plurality of convex strips are evenly arranged on the inner surface of the synchronous belt 35. The moving direction of the synchronous belt 35 is parallel to the length direction of the front lead screw 11. In front of the synchronous belt 35, there is a material pulling guide rail 36 parallel to it. A material pulling guide rail slider is slidably clamped on the material pulling guide rail 36. A jaw mounting plate 34 is provided on the top of the material pulling guide rail slider. A jaw is provided on the jaw mounting plate 34. The jaw includes a jaw upper plate 38 and a jaw lower plate 39. A synchronous belt pressing plate 32 is provided on one side surface of the jaw mounting plate 34. The synchronous belt 35 passes through the synchronous belt pressing plate 32. A plurality of grooves engaging with the convex strips are provided in the synchronous belt pressing plate 32. The left end of the jaw mounting plate 34 is provided with the jaw upper plate 38. A material clamping cylinder is provided at the bottom of the jaw upper plate 38. The output end of the material clamping cylinder is vertically upward and connected with the jaw lower plate 39. The material clamping cylinder is not in contact with the top surface of the robot arm base 29. Robot arm support plates 37 are symmetrically provided on the front and rear sides of the top surface of the robot arm base 29. A guide plate 33 is provided on the top of the robot arm support plate 37.
[0033] Specifically, when the material pulling module is working: start the stepping motor 31, the stepping motor 31 drives the main pulley to rotate, and drives the secondary pulley to rotate through the synchronous belt 35. Since the synchronous belt 35 passes through the synchronous belt pressing plate 32, and there are multiple grooves in the synchronous belt pressing plate 32 that engage with the convex strips, when the synchronous belt 35 moves, the jaw mounting plate 34 can be driven to move through the synchronous belt pressing plate 32, and then drive the jaws to move. Therefore, the jaws can be controlled to move to the workpiece, and the workpiece can be clamped and pulled to the robotic arm support plate 37 and then released. Specifically, the clamping and releasing are realized by the clamping cylinder controlling the up and down movement of the jaw lower plate 39.
[0034] The bottom surface of the robotic arm support plate 37 is movably connected to the top surface of the robotic arm base 29 through a steel ball slide rail structure. There are multiple groups of mounting holes with different spacings on the top of the robotic arm support plate 37. The guide plate 33 is fixedly connected to the robotic arm support plate 37 through the mounting holes. Different groups of mounting holes correspond to fixing steel rings 24 of different sizes, improving the applicability of the device. There are two clamping cylinders on the top of the robotic arm base 29. The two clamping cylinders are distributed below the corresponding robotic arm support plates 37. The output ends of the two clamping cylinders are away from each other and are connected with a cylinder push plate 40. The top of the cylinder push plate 40 is fixedly connected to the bottom of the corresponding robotic arm support plate 37. The bottom of the cylinder push plate 40 does not contact the top of the robotic arm base 29.
[0035] Specifically, during use, according to the size of the workpiece, that is, the size of the steel ring 24, select a suitable mounting hole, install the guide plate 33. When the workpiece moves to the specified position, start the two clamping cylinders. The two clamping cylinders drive the cylinder push plate 40 to move, making the two cylinder push plates 40 approach each other, so that the two robotic arm support plates 37 can approach each other, and then drive the two guide plates 33 to approach each other to clamp the workpiece and ensure the centering of the workpiece.
[0036] Workflow: Start the material pulling motor 2. Drive the material pulling module to move leftward to the stock preparation module through the material pulling side plate 30 and the robotic arm base 29. (The stock preparation module is an area for storing workpieces, which is common knowledge in the art and belongs to the prior art.) Then, through the operation of the material pulling module, make the gripper clamp the workpiece, and drive the gripper to move through the synchronous belt 35, so that the workpiece moves to the designated position, release the gripper, and the gripper returns to the initial position. At this time, start the two clamping cylinders, and the two clamping cylinders drive the cylinder push plate 40 to move, so that the two cylinder push plates 40 approach each other, which can make the two robotic arm support plates 37 approach each other, and then drive the two guide plates 33 to approach each other to clamp the workpiece and ensure the centering of the workpiece. Next, start the loading motor 1, drive the material suction module to move to the position of the workpiece, and through the operation of the material suction module, adjust the position of the suction cup assembly with the upper cylinder 12 until the suction cup assembly sucks the workpiece. Subsequently, control the overall material pulling module to move back to the initial position to the right. The material suction module then transports the workpiece to the processing area, and uses the lower cylinder 16 to put down the workpiece and wait for the processing to end. The workpiece is sucked by the suction cup assembly at the bottom of the material pulling module and moves to the cleaning area, and the workpiece is put down for cleaning. Finally, the material suction module sucks the workpiece up again, blows off the excess moisture through the air curtain tube, and then places it on the material pulling module. The gripper is enabled again to push the workpiece back to the stock preparation module.
[0037] A loading module support 4 is fixedly installed at the right end of the back of the loading guide rail mounting plate 6, and a support connecting plate 5 is provided at the top of the loading module support 4; the overall volume of this device is small, the floor area is small, the cost is low, and through the settings of the loading module support 4 and the support connecting plate 5, the external hanging of the material suction module and the material pulling module can be realized on the basis of the original model, the installation is simple and convenient, the use is convenient, and the limitation of the use site is small, which is worthy of popularization.
[0038] The material suction cylinder adopts the design of a double cylinder with an upper cylinder 12 and a lower cylinder 16, which increases the stroke of the material suction module, can achieve more movements, and can complete more tasks.
[0039] This device realizes the common movement of workpiece loading and unloading through the loading motor 1 and the material pulling motor 2. By adjusting the relative positions between the two, the repeatability of the loading position during the wafer cutting process is ensured, the stability of the cutting quality is guaranteed, the degree of automation is high, and the influence of situations such as low proficiency and weak professional ability of operators on the processing is avoided. It solves the problems of long stock preparation time, low position repeatability, and poor wafer cutting accuracy during the cutting process of the dicing machine.
