[0032] Example: Refer to Figure 1 A laser-electrodeposition composite surface coating system is shown, which includes a lifting device 2, a clamp 3 and a translation device 4 arranged in a first space above the base ground 1, and two sets of laser irradiation devices 5 and an electrodeposition device 6 arranged in a second space below the base ground 1.

[0033] The basic ground 1 has a width extending along the x-axis direction and the y-axis direction, and divides the space into a first space and a second space along the z-axis direction. The basic ground 1 can be an actual ground, in which case the first space is the above-ground space and the second space is the underground space. In this embodiment, the basic ground 1 is a floor slab that divides the factory space into upper and lower spaces. The first space and the second space are partially connected through a skylight.

[0034] The lifting device 2 is installed on the base ground 1 , and it can be any one in the prior art, for example, including a frame, a lifting rope 21 and a control cylinder 22 .

[0035] The clamp 3 includes a connecting rod 31 arranged along the x-axis direction, a pair of pull rods 32 formed by vertical bending and extending from the two ends of the connecting rod 31, a clamp plate 33 screwed on the free end of the pull rod 32, a lifting ear 34 welded on the top of the connecting rod 31, and a first connecting block 35 welded on the middle of the connecting rod 31.

The first connecting block 35 is a rectangular block connected to the connecting rod 31 in a "cross" shape.

[0036] The translation device 4 includes a pair of translation seats 41 arranged on both sides of the skylight, a driving unit 42 installed through the translation seats 41, and a second docking block 43 driven by the driving unit 42 so as to be movable along the x-axis direction.

[0038] The two sets of laser irradiation devices 5 are both prior art, for example, they can be the devices described in the invention patent application with publication number CN112176383A. The two sets of laser irradiation devices 5 are arranged at intervals. The laser irradiation devices 5 can form an irradiation working area, which are marked as laser irradiation device No. 1 51 and laser irradiation device No. 2 52 respectively.

[0039] The electrodeposition device 6 is improved based on the electrodeposition device of the prior art, and includes a deposition tank 61 loaded with a deposition liquid, a DC pulse power supply, and a tool anode 62 and a cathode socket 63 respectively connected to the positive and negative electrodes of the DC pulse power supply are provided in the deposition tank 61. The deposition tank 61 is open toward the translation device 4, and the tank wall thereof which is arranged parallel to the tool anode 62 and facing the laser irradiation device 5 is a glass wall. The tool anode 62 has the same width as the stainless steel plate 7, and it is installed through the anode socket 64. The setting position of the tool anode 62 on the x-axis is located between the two sets of laser irradiation devices 5. The tool anode 62 can form an electrodeposition working area.

[0040] The working principle of a laser-electrodeposition composite surface coating system of this embodiment is as follows:

[0041] First, the two stainless steel plates 7 are clamped by the clamping plate 33 and lifted by the lifting device 2. The lifting device 2 transfers the two stainless steel plates 7 (respectively marked as stainless steel plate No. 1 ① and stainless steel plate No. 2 ②) to the top of the translation device 4, and at the same time moves the second connecting block 43 to the starting position, which is set to be directly below the first connecting block 35;

[0042] Subsequently, the lifting device 2 lowers the two stainless steel plates 7, passes through the gap between the screw rod 421 and the limit rod 423, and enters the deposition tank 61 loaded with the deposition liquid through the skylight; at the same time, the No. 1 laser irradiation device 51 is preheated;

[0043] Then, the stainless steel plate 7 is lowered into place. At this time, (1) the stainless steel plate ① of No. 1 is located in the irradiation working area corresponding to the laser irradiation device ① of No. 1, (2) the stainless steel plate ② of No. 2 is located in the electrodeposition working area, and the bottom of the stainless steel plate ② of No. 2 is inserted into the cathode socket 63, (3) the first docking block 35 is connected to the second docking block 43; at this time, the cathode socket 63 and the anode socket 64 are not powered; at the same time, the laser irradiation device ② of No. 2 is preheated;

[0044] After holding for a period of time, the translation device 4 drives the clamp 3 to move along the x-axis direction. At this time, (1) the No. 2 stainless steel plate ② is translated to the irradiation working area corresponding to the No. 2 laser irradiation device ②. (2) After the No. 1 stainless steel plate ① obtains a high temperature of a part or the whole width under the irradiation treatment of the No. 1 laser irradiation device ①, it is translated to the electrodeposition working area, and the bottom of the No. 1 stainless steel plate ① is inserted into the cathode socket 63. At this time, the cathode socket 63 and the anode socket 64 are energized and kept energized, and the No. 1 stainless steel plate ① starts the electrodeposition treatment. (3) The No. 1 laser irradiation device ① is turned off;

[0045] After holding for a period of time, the translation device 4 drives the clamp 3 to move in the opposite direction along the x-axis. At this time, (1) the stainless steel plate No. 1 ① returns to the irradiation working area corresponding to the laser irradiation device No. 1 ① after the first electroplating treatment, and starts the second laser irradiation heating of the local or whole width. (2) The stainless steel plate No. 2 ② returns to the electroplating working area, and the bottom of the stainless steel plate No. 2 ② is inserted into the cathode socket 63. The cathode socket 63 and the anode socket 64 remain energized. After obtaining a high temperature of the local or whole width under the irradiation treatment of the laser irradiation device No. 2 ②, the stainless steel plate No. 2 ② starts the electroplating treatment. (3) The laser irradiation device No. 2 ② is turned off.

[0046] This process is repeated until the process benchmark is completed. Finally, the lifting device 2 lifts the two stainless steel plates 7 and transfers them to the hot air drying process. Generally speaking, each stainless steel plate 7 can be treated with laser-electrodeposition composite coating after 2-3 times of electroplating.

[0047] As a preferred embodiment, a pair of limit rings 422 are arranged at intervals on at least the screw rod 421 of the driving unit 42 to limit the displacement of the second docking block 43 between the pair of limit rings 422. The limit ring 422 is fixed to the screw rod 421 by welding. In this embodiment, a limit ring 522 is arranged on both the screw rod 421 and the limit rod 423. The setting position of the limit ring 422 should satisfy: when the second docking block 43 moves to the limit position of the limit ring 422 on the first side, the stainless steel plate 7 on the first side is located in the irradiation working area of ​​the first side; when the second docking block 43 moves to the limit position of the limit ring 422 on the second side, the stainless steel plate 7 on the second side is located in the irradiation working area of ​​the second side.

[0048] At the same time, the translation device 4 also includes a pair of protective covers 44. The protective covers 44 are screwed or clamped to cover the areas on both sides of the limiting ring 422, and are provided with through grooves 45 suitable for the connecting rod 31 to pass through.

[0049] As a preferred embodiment, the translation seat 1 is arranged on the base ground 1 through a longitudinal moving device 8. Specifically, the longitudinal moving device 8 includes a pair of rails 81 arranged along the y-axis direction, and an electric slider 82 matched with the rails 81, and the translation seat 1 is fixedly mounted on the mounting platform of the electric slider 82 in a screw connection manner.

[0050] Compared with the aforementioned working principle, the above preferred embodiment also requires that before the coating process starts, the electric slider 82 is moved along the y-axis direction by the control system so that the distance between the stainless steel plate 7 and the laser irradiation device 5 meets the value set by the process.
