Description

Technical Field

[0001] The utility model relates to the technical field of shot peening treatment, and particularly relates to an automatic shot peening loading and unloading unit. Background Art

[0002] Shot peening treatment is a process method that impacts the surface of a workpiece by high-speed spraying of iron shots or sand shots to improve its mechanical properties and change the surface state. During the production process of castings, since there are often burrs, scale and uneven roughness on the surface of castings, these defects not only affect the appearance quality, but also reduce the mechanical properties and corrosion resistance of parts. Therefore, shot peening treatment is an indispensable link.

[0003] In large-scale casting production, an automated shot peening machine is often used to complete the shot peening treatment process of castings, which significantly improves production efficiency and quality stability. However, the loading and unloading process of workpieces still relies on manual operation. Due to the speed limit and fatigue factors of manual operation, it is difficult to achieve continuous and efficient loading and unloading operations, resulting in limited production capacity of the entire production line. This not only increases labor costs, but also reduces overall production efficiency. In addition, during the shot peening treatment process, the uncontrollability of manual operation increases safety risks.

[0004] Therefore, it is necessary to develop a shot peening treatment unit that can automatically complete the loading and unloading operations to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to provide an automatic shot peening loading and unloading unit for the problems existing in the prior art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An automatic shot peening loading and unloading unit includes a shot peening machine, a loading and unloading robot and a feeding and discharging unit. The feeding and discharging unit includes a loading frame, a discharging frame, an identification camera and a transfer table. The shot peening machine, the loading frame and the discharging frame are arranged around the loading and unloading robot. The loading port of the shot peening machine faces the loading and unloading robot. The loading frame and the discharging frame are arranged in parallel. The identification camera is located above the loading frame. The transfer table is located on one side of the loading frame, and the height of the transfer table is between the identification camera and the loading frame.

[0008] The loading and unloading robot completes the automated loading and unloading process of the shot peening machine, significantly reducing the time and labor requirements of manual operation, achieving continuous and efficient loading and unloading operations, thereby improving the production capacity and efficiency of the entire shot peening treatment production line. Automated loading and unloading reduces the uncertainty caused by human factors and reduces safety risks caused by improper manual operation or fatigue.

[0009] The transfer table is used to temporarily store a single casting taken out from the loading frame, facilitating the identification camera to identify the specific shape, size, and placement posture of the casting to be processed.

[0010] Preferably, the loading and unloading robot, the shot blasting machine, and the identification camera are internally provided with wireless transmission modules, and the loading and unloading robot is wirelessly connected to the identification camera and the shot blasting machine respectively.

[0011] On the one hand, the identification camera is used to determine whether there is a casting in the loading frame, and on the other hand, it is used to determine the placement posture of the casting to be processed on the transfer table. The identification camera sends the identification result to the loading and unloading robot, and the loading and unloading robot transports the casting to the shot blasting machine according to the identification result of the identification camera.

[0012] Preferably, the loading and unloading unit further includes a camera support, which includes a support frame and an extension frame. The support frame and the extension frame are perpendicularly connected. The support frame is located on one side of the loading frame, and the extension frame is located above the loading frame. The identification camera is arranged on the extension frame.

[0013] The design of the camera support enables the identification camera to clearly capture the castings in the loading frame and on the transfer table, improving the accuracy and efficiency of identification.

[0014] Preferably, the loading and unloading robot includes a base, a robot body, and a robot execution end. The robot body is rotatably connected to the base, and the robot execution end is arranged on the robot body.

[0015] Preferably, the robot execution end includes a base, a connecting arm, and a gripper. A first motor is provided at one end of the base, and a second motor is provided at one end of the connecting arm. The base is rotatably connected to the connecting arm through the first motor, and the connecting arm is rotatably connected to the gripper through the second motor.

[0016] The robot body drives the robot execution end to rotate between the shot blasting machine, the loading frame, and the unloading frame to complete loading and unloading, and the robot execution end grabs the casting through the gripper.

[0017] Preferably, the transfer table is located between the loading and unloading robot and the loading frame, and the loading frame is located between the camera support and the unloading frame.

[0018] Preferably, both the transfer table and the loading frame are within the shooting range of the identification camera.

[0019] By reasonably arranging the transfer table and the camera support, the transfer table is prevented from blocking the loading frame, ensuring that the identification camera can capture the casting conditions in the transfer table and the loading frame in real time and accurately, providing reliable identification information for the loading and unloading robot.

[0020] Preferably, a safety fence is provided on one side of the shot blasting machine close to the maintenance passage, and the safety fence surrounds the shot blasting machine partially.

[0021] The setting of the safety fence effectively isolates the working area of the shot blasting machine, preventing safety accidents caused by non-staff entering.

[0022] Compared with the prior art, the beneficial effects of the present utility model are:

[0023] The present utility model uses a loading and unloading robot to complete the automated loading and unloading process of the shot blasting machine, significantly reducing the time and labor requirements of manual operations, achieving continuous and efficient loading and unloading operations, thereby improving the production capacity and efficiency of the entire shot blasting production line. The automated loading and unloading reduces the uncertainties caused by human factors and lowers the safety risks caused by improper human operations or fatigue.

[0024] In the present utility model, the identification camera is used on the one hand to determine whether there is a casting in the loading frame, and on the other hand to determine the placement posture of the casting to be processed on the transfer table. The loading and unloading robot takes the casting according to the identification result of the identification camera, enabling the loading and unloading robot to adapt to castings of different sizes and shapes.

The loading port of the shot peening machine 1 faces the loading and unloading robot 2.

[0034] The feeding and discharging unit includes a loading frame 3, a discharging frame 4, an identification camera 5, a camera support 6, and a transfer table 7. The loading frame 3 and the discharging frame 4 are arranged in parallel. The loading frame 3 is used to load the casting 8 to be processed, and the discharging frame 4 is used to place the casting 8 after shot peening treatment.

[0035] The loading frame 3 is located between the camera support 6 and the discharging frame 4. The camera support 6 includes a support frame and an extension frame. The support frame and the extension frame are vertically connected. The support frame is located on one side of the loading frame 3, and the extension frame is located above the loading frame 3.

[0036] The identification camera 5 uses a 3D industrial camera. The identification camera 5 is arranged on the extension frame. The identification camera 5 is located directly above the center position of the loading frame 3. The shooting range of the identification camera 5 is a rectangular range of 1.7m × 1.4m, and the preset working distance of the identification camera 5 is 1.5 - 2.0m.

[0037] The transfer table 7 is located between the loading and unloading robot 2 and the loading frame 3. The height of the transfer table 7 is between the identification camera 5 and the loading frame 3. Both the transfer table 7 and the loading frame 3 are within the shooting range of the identification camera 5.

[0038] The loading frame 3 is used to place the castings 8 to be processed, and the unloading frame 4 is used to place the castings 8 that have completed the shot peening treatment. The castings 8 are stacked layer by layer in the loading frame 3, and the castings 8 on the same layer are arranged in a matrix, which is convenient for the loading and unloading robot 2 to grab according to the preset program.

[0039] The loading and unloading robot 2 includes a base, a robot body and a robot execution end 201 . The robot body is rotatably connected to the base, and the robot execution end 201 is arranged on the robot body.

[0040] The robot execution end 201 includes a base 202, a connecting arm 203 and a clamp 204. One end of the base 202 is provided with a motor 1, and one end of the connecting arm 203 is provided with a motor 2. The base 202 is rotatably connected to the connecting arm 203 through the motor 1, and the connecting arm 203 is rotatably connected to the clamp 204 through the motor 2.

[0041] The robot body drives the robot execution end 201 to rotate between the shot peening machine 1 , the loading frame 3 and the unloading frame 4 , and the robot execution end 201 drives the clamping claw 204 to move to the casting 8 to be grasped, and the clamping claw 204 grasps the casting 8 .

[0042] The shot peening machine 1 is provided with a safety fence 9 on one side close to the maintenance passage, and the safety fence 9 is partially arranged around the shot peening machine 1 .

[0043] The loading and unloading robot 2 , the shot blasting machine 1 and the recognition camera 5 are equipped with built-in wireless transmission modules, and the loading and unloading robot 2 is wirelessly connected to the recognition camera 5 and the shot blasting machine 1 respectively.

[0044] The working process of this embodiment is as follows: the recognition camera 5 captures the loading frame 3 loaded with the casting 8 to be processed, and sends the recognition result to the loading and unloading robot 2, which takes out a casting 8 from the loading frame 3 and places it on the transfer table 7.

[0045] After the loading and unloading robot 2 completes the grabbing, it notifies the recognition camera 5 , and the recognition camera 5 will take pictures again to identify the position and posture of the casting 8 on the transfer table 7 .

[0046] The loading and unloading robot 2 grabs the casting 8 on the turntable 7 according to the recognition result, adjusts the posture of the casting 8, and finally puts it on the turntable tooling of the waiting shot blasting machine 1.

[0047] After the loading and unloading robot 2 completes the loading, it notifies the waiting shot peening machine 1, and the shot peening machine 1 starts the shot peening equipment to process the casting 8. After the shot peening machine 1 completes the processing cycle, the turntable rotates to turn out the processed casting 8 and notifies the loading and unloading robot 2.

[0048] The loading and unloading robot 2 will grasp the castings 8 that have been processed and place the castings 8 into the unloading frame. The loading and unloading robot 2 will send the castings 8 into each shot blasting machine 1 respectively according to the above steps, and send the processed castings 8 into the unloading frame.

[0049] When the recognition camera 5 detects that there are no castings 8 in the loading frame 3, it will notify the loading and unloading robot 2 to stop loading.
