[0003] The electrophoretic process in the paint shop requires that the fulcrum of the electrophoretic sled be electrically conductive to the car body. The electrophoretic paint will be attached to the electrophoretic sled when passing through the electrophoretic tank. The attached electrophoretic sled will affect the conductivity between the sled and the car body, thereby affecting the electrophoretic quality of the car body.

[0038] Example

[0039] Reference Figure 1-Figure 6, is a laser workpiece cleaning equipment disclosed in the utility model, the utility model includes: a processing component, a laser cleaning component, a dust collection component, an electric control cabinet 600 and an operating station 700, the processing component includes a bracket 200 and a roller bed 500, the roller bed 500 is located below the bracket 200; the processing component includes a three-dimensional moving component 220, the laser cleaning component includes a laser cleaning head 130, the laser cleaning head 130 is fixedly connected to the moving component, the three-dimensional moving component 220 drives the laser cleaning head 130 to move arbitrarily in a three-dimensional direction, the three-dimensional moving component 220 can automatically move along three directions, and can be electric or pneumatic; the dust collection component includes an air vent 320, at least one air vent 320 is fixedly connected to the top of the bracket 200, the air vent 320, the laser cleaning head 130, etc. are reasonably arranged, and the sled body can be transported away from the cleaning station by the roller bed 500 after cleaning without interfering with the air vent 320, the laser cleaning head 130, etc. The roller bed 500, the positioner 210, the laser cleaning head 130, the dust collection assembly, and the three-dimensional moving assembly 220 are controlled by PLC interlocking to complete the cleaning work.

[0040] The utility model also includes a control system, which is composed of an electric control cabinet 600, an operation station 700, a PLC, a cleaning control card, an industrial computer, cables, a bridge, and a servo driver.

[0041] The sled is transported to the cleaning station by the roller bed 500, the positioner 210 positions the sled, the three-dimensional moving component 220 drives the laser cleaning head 130 to move to the sled fulcrum, and starts to clean the sled fulcrum. The dust suction component is turned on to absorb the cleaning dust. After the cleaning of this fulcrum is completed, it can be moved to the next space for cleaning by the three-dimensional moving component 220. After the cleaning is completed, the three-dimensional moving component 220 returns to its position and the dust collector 300 is turned off. After that, the positioner 210 is released, and the roller bed 500 drives the sled to leave the cleaning station.

[0042] The sled is transported on a roller bed 500 or other conveying equipment, and the position of the sled can be located by a positioner 210. The laser 100 is connected to the laser cleaning head 130 through an optical fiber, and the laser cleaning head 130 is composed of a galvanometer 133, a field lens 131, and a protective lens. The laser cleaning head 130 is connected to a moving component, and the moving component can move in three directions: X, Y, and Z. An air vent 320 is provided at the fulcrum where the sled needs to be cleaned, and the air vent 320 is connected to the vacuum cleaner 300 through an air duct 310. Outside the cleaning area, a protective plate 800 is provided to protect the cleaning area.

[0043] like Figure 7 In an optional embodiment, the laser cleaning component includes a laser 100 , on which a laser generator 110 and an optical fiber outlet 120 are disposed.

[0044] Specifically, laser cleaning can provide an efficient cleaning process that can quickly and thoroughly remove dirt, grease, coatings or other contaminants from the surface. Compared with traditional cleaning methods, laser cleaning is a non-contact cleaning technology that avoids damage or wear caused by physical contact. The laser cleaning system can achieve a high degree of precision and can focus on cleaning specific areas without unnecessary impact on surrounding areas. Laser cleaning may require fewer chemical cleaning agents, thereby reducing the impact on the environment, and due to efficient cleaning, it can also reduce energy consumption. The laser cleaning system can be integrated into an automated production line to realize an automatic cleaning process and improve production efficiency. Laser cleaning is generally applicable to a variety of materials, including metals, plastics, ceramics, etc., so it can be widely used in different industries and fields. Usually no residue is left after cleaning, which improves the quality of cleaning.

[0045] In an optional embodiment, the dust collection component also includes a dust collector 300 and an air duct 310. The air duct 310 connects the dust collector 300 and the air outlet 320. The dust collector 300 can be started and stopped by PLC. The air outlet 320 is arranged obliquely downward at a certain angle to ensure good adsorption capacity.

[0046] Specifically, the air duct 310 connects the vacuum cleaner 300 and the air outlet 320. This design can effectively transfer the negative pressure generated by the vacuum cleaner 300 to the cleaning area, thereby improving the vacuuming effect. At the same time, through the connection of the air duct 310, the vacuum cleaner 300 and the air outlet 320 can be arranged more flexibly to meet the needs of different working scenes. The air outlet 320 is arranged obliquely downward and at a certain angle. This design helps to ensure the vacuuming effect. The angle setting enables the vacuuming air outlet 320 to be better aligned with the cleaning area, thereby improving the accuracy and efficiency of vacuuming.

[0047] In an optional embodiment, a positioner 210 is fixedly connected to the roller bed 500 , and the positioner 210 is used to fix the skid body 400 .

[0048] Specifically, the design and installation of the positioner 210 can provide precise position control to ensure that the fixed position of the skid 400 on the roller bed 500 is accurate. This is very important for processing tasks that require high precision, and can avoid processing errors caused by position deviations. The use of the positioner 210 can increase the stability of the system. Through the fixed connection, the skid 400 is not easy to move or shake during the operation of the roller bed 500, thereby ensuring the stability and consistency of the processing. The presence of the positioner 210 makes the replacement and adjustment of the skid 400 faster and easier. This helps to reduce production line downtime and improve production efficiency, especially when frequent tool changes or adjustments to processing parameters are required. The use of the positioner 210 can reduce the risk of human operating errors. The operator only needs to operate according to the designed positioner 210, reducing the possibility of equipment damage or production errors caused by improper operation.

[0049] In an optional embodiment, a protective plate 800 is further provided around the processing assembly, and the protective plate 800 is provided with openings at both ends of the roller bed 500 .

[0050] Specifically, the provision of the protective plates 800 can improve the safety of the operator. They can prevent accidental contact with the moving roller bed 500 or the processing component, reducing the risk of injury due to careless operation. The protective plates 800 can protect the surrounding materials of the processing component from the influence of the external environment, such as chips, coolant, etc. This helps to extend the service life of the processing component and reduce damage caused by external factors. The provision of the protective plates 800 can effectively prevent debris such as chips and coolant from splashing into the surrounding area, keeping the working environment clean. This is beneficial to improving the comfort of the operator and maintaining the cleanliness of the workplace.

[0051] like Figure 8 The laser cleaning head 130 includes a field lens 131, goggles 132, a vibrating mirror 133 and an optical fiber inlet 134. The optical fiber inlet 134 is connected to the vibrating mirror 133. The bottom of the vibrating mirror 133 is fixedly connected to the field lens 131. The bottom of the field lens 131 is fixedly connected to the goggles 132. The optical fiber outlet 120 is connected to the optical fiber inlet 134 through an optical fiber. The cleaning surface can be adjusted to conform to the shape.

[0052] Specifically, the laser cleaning head 130 allows for contour adjustment of the cleaning surface, which means that it can be flexibly adjusted according to different cleaning requirements and workpiece shapes to improve the cleaning effect. The laser cleaning head 130 can achieve precise control of the cleaning beam through the synergy of the galvanometer 133 and the field lens 131, making the cleaning process more delicate and accurately positioned. Through optical fiber connection, the laser cleaning head 130 can achieve more flexible layout and use, and the use of optical fiber improves the applicability and flexibility of the system. The optical elements (field lens 131, galvanometer 133, etc.) in the laser cleaning head 130 can maintain a relatively stable relative position through a fixed connection, which helps to maintain the accuracy and stability of the cleaning system. The design of the laser cleaning head 130 makes the cleaning process more efficient. Through accurate control and shape adjustment of the light beam, it can better adapt to workpieces of different shapes and materials and improve cleaning efficiency.

[0053] In addition, the field lens 131 is mainly used to control the diffusion angle and shape of the laser beam. It can adjust the focusing degree and cleaning area of ​​the laser beam to make it more suitable for workpieces of different shapes and sizes. The adjustment of the field lens 131 can affect the range and depth of cleaning, and improve the accuracy and applicability of cleaning. The goggles 132 are used to protect the eyes of the operator from the hazards of laser radiation. The laser radiation generated during the laser cleaning process may cause damage to the human eye, so the design of the goggles 132 is to prevent the laser from directly shining into the eyes of the operator to ensure the safety of the operation. The galvanometer 133 is used to control the direction and position of the laser beam. By vibrating or rotating the galvanometer 133, the laser beam can be moved on the cleaning surface to achieve comprehensive cleaning of the workpiece. The movement of the galvanometer 133 can be precisely adjusted by the control system to achieve highly accurate control of the cleaning process. The role of the galvanometer 133 is to ensure that the laser can cover the entire cleaning area and improve the efficiency and uniformity of cleaning.

[0054] Reference Figure 9-11 The three-dimensional moving assembly 220 includes a Y-axis rod and two Z-axis rods, the two ends of the Y-axis rod move on the two Z-axis rods, the Y-axis rod includes a forward lead screw 221 and a reverse lead screw 222, the forward lead screw 221 is docked with the reverse lead screw 222, and the forward lead screw 221 is docked with the reverse lead screw 222, so that only one Y-axis driving motor 225 is needed to complete the symmetrical movement. The Y-axis driving motor 225 can be arranged on one side of the lead screw, or in the middle of the forward lead screw 221 and the reverse lead screw 222.

[0055] In an optional embodiment, two Z-axis moving assemblies 224 are slidably connected to the Y-axis rod, and the two Z-axis moving assemblies 224 move on the forward lead screw 221 and the reverse lead screw 222 respectively. The laser cleaning head 130 is fixedly connected to the Z-axis moving assembly 224, and the laser cleaning head 130 can successively clean one or more fulcrums of the sled under the action of the three-dimensional moving assembly 220. The end of the Y-axis rod is fixedly connected to the Y-axis moving assembly 223, and the Y-axis moving assembly 223 moves on the Z-axis rod. The Y-axis driving motor 225 is fixedly connected to the Y-axis rod.

[0056] Reference Figure 12-13 , there can be only one Z-axis moving assembly 224. When one Z-axis moving assembly 224 is used, there is only one corresponding laser cleaning head 130. At the same time, the Z-axis moving assembly 224 only moves on the forward lead screw 221, and the reverse lead screw 222 is not provided. Although there is only one Z-axis moving assembly 224, the laser cleaning head 130 can still clean the skid body, and the same effect as the double Z-axis moving assembly 224 can be achieved. However, the single Z-axis moving assembly 224 is not as efficient as the double Z-axis moving assembly 224, and the cleaning speed will be slightly slower.

[0057] The working principle and beneficial effects of the utility model are as follows: the roller bed 500 transports the skid body 400 into the processing assembly, the processing assembly cleans the skid body 400, and the cleaned skid body 400 is then transported to the next point by the roller bed 500. This arrangement allows the skid body 400 to be cleaned without going offline, ensuring the flexibility of cleaning the skid body 400 and improving the cleaning efficiency. The laser cleaning head 130 is driven to move freely by the three-dimensional moving assembly 220, so that the laser cleaning head 130 can reach any position on the skid body 400, making the cleaning more comprehensive. Using laser for cleaning reduces noise, and the laser cleaning method will not damage the substrate, ensuring the integrity of the workpiece. Use a vacuum assembly to vacuum the processing assembly to keep the processing position clean.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
