Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a full-automatic terminal block grinding device based on visual guidance. Background Art

[0002] The terminal block is a connector produced to facilitate the connection of wires. It is essentially a piece of metal with wires inserted at both ends. It can be tightened or loosened with screws. It is suitable for interconnecting a large number of wires and is very convenient and fast. In the actual production process, it is necessary to perform drilling, tapping and other processes on its surface. At present, the traditional processing method of terminal blocks is to process them one by one using a fixture positioning method. After each processing is completed, the finished parts need to be removed manually and the workpiece needs to be re-clamped before the next processing can be carried out. This is inefficient and time-consuming and labor-intensive.

[0003] A Chinese patent discloses a continuous processing line and processing technology for terminal blocks (authorization announcement number CN111817109B). This patented technology can process workpieces through automatic clamping, feeding, clamping and other processes, saving manpower and material resources and improving processing efficiency. However, it cannot adapt to the processing of terminal blocks of different sizes and has a low degree of automation. Therefore, the utility model provides a fully automatic terminal block grinding device based on visual guidance to solve the problems raised in the above background technology.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a fully automatic terminal block grinding device based on vision guidance includes a table. On the left side of the table is a loading line body 1. Above the middle of the loading line body 1 is a 3D vision component A 2. At the center of the table is a processing station. In the middle of the processing station is a lower grinding table 4. Outside the processing station is a clamping and rotating component 6. On the right side of the table is an unloading line body 7. Above the table is a truss module 3. The front and rear sides of the truss module 3 are slidably connected to the guide rails. A grinding tool is installed on the truss module 3. Below the middle of the truss module 3 is an up and down cylinder. Below the up and down cylinder is a jaw. Directly above the processing station is a 3D vision component B 5. The clamping and rotating component 6 is composed of cylinders on the front and rear sides and clamps on the left and right sides. The front and rear clamps are connected to the cylinders through two parallel movable rods. The middle of the clamp is rotatably connected to a clamping plate to drive the clamping plate to rotate. The grinding tool is equipped with a heating system that can raise the temperature to soften the epoxy resin and ceramic powder polymer to be ground.

[0024] On the right side of the loading line body is a blocking and positioning system composed of symmetric plate edges on the front and rear to block the workpiece from moving forward. On the front and rear sides of the loading line body 1 are gratings that are on the same plane as the 3D vision component A 2 to position the workpiece. Below the lower grinding table 4 is a lifting device to control the height of the grinding table for receiving materials. The grinding tool is installed on an up and down moving component to control the height of the grinding tool. On the front side of the truss module 3 is a display screen, and on the right side of the truss module 3 is a controller. Detailed implementation mode:

[0026] 1. Manually place the workpiece on the loading line body 1. After pressing the start button, the loading line body 1 sends the workpiece under the 3D vision component A 2, and the grating installed on both sides of the loading line body 1 issues a in-place command.

[0027] 2. The 3D vision component A 2 is activated to scan the workpiece below to determine parameters such as the outer diameter, height, and number of parts to be ground of the workpiece.

[0028] 3. After determining the parameters, the loading line 1 continues to start and brings the workpiece to the end of the belt line, where there is a blocking positioning system to position the workpiece.

[0029] 4. Based on the outer diameter information provided by the 3D vision component A2, the truss module 3 moves horizontally to different positions to ensure that it is directly above the center of the workpiece.

[0030] 5. The upper and lower cylinders on the truss module 3 drive the clamp to descend, clamp the workpiece and then rise.

[0031] 6. The truss module 3 drives the workpiece to the top of the lower grinding table 4.

[0032] 7. The height above the lower grinding table 4 is adjusted to a suitable height for receiving the material according to the height information provided by the 3D vision component A2.

[0033] 8. After receiving the material, the clamping and rotating assembly 6 clamps the workpiece to position it.

[0034] 9.3D vision component B5 scans the workpiece to determine the amount and location information required for grinding.

[0035] 10. According to the information sent by the 3D vision component B5, the truss module 3 drives the grinding tool to each calibrated position.

[0036] 11. After it is in place, the upper and lower axes of the truss module 3 first drive the grinding tool to move down to the position, and then the cylinder pushes the clamp to clamp the grinding area.

[0037] 12. After clamping, the motor drives the grinding tool to rotate and cut off the overflow.

[0038] 13. The grinding tool is equipped with a heating system that can increase the temperature and soften the epoxy resin and ceramic powder polymer that need to be ground.

[0039] 14. After grinding is completed, release the clamping jaws and the truss module 3 drives the grinding tool to move upward.

[0040] 15. The clamping and rotating assembly 6 drives the workpiece to flip 180 degrees.

[0041] 16.3D vision component B5 scans the workpiece to determine the amount and position information of the second surface that needs to be polished.

[0042] 17. Then repeat the same process to complete the polishing of the second side.

[0043] 18. After completion, the workpiece is clamped by the truss module 3 and sent to the unloading line 7.

[0044] 19. The unloading line 7 starts to bring the workpiece out of the equipment.

[0045] After loading workpieces of different types, the present utility model determines the product model by using a 3D camera and calls different processing recipes, and uses 3D vision to determine the grinding position and gives the coordinates of each point. Calibrating the moving coordinate system of the truss and the 3D vision coordinate system enables the 3D vision to directly guide the movement of the truss, which can all be achieved by the existing technology.

[0046] The present utility model uses a movable jaw controlled by a cylinder to clamp the grinding area of the workpiece and then grinds it, and can be compatible with grinding areas of different sizes of different products. Heating the grinding tool softens the epoxy resin and ceramic polymer attached to the copper column, making grinding easier.

[0047] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
