The vacuum suction cups 2 are connected to a vacuum device (such as a vacuum generator, etc., not shown in the figure) through a pipe, and an L-shaped support plate 3 is slidably provided on the side of the support table 1.

[0031] Two bearing seats 10 are fixedly installed on the side of the support platform 1, and a screw 11 is rotatably connected between the two bearing seats 10. An internal threaded hole threadedly connected to the screw 11 is provided on the L-shaped support plate 3. A forward and reverse motor 12 for driving the screw 11 to rotate is fixedly installed on the end of one of the bearing seats 10. A limit block is fixedly installed on the L-shaped support plate 3, and a limit groove for the limit block to slide is provided on the support platform 1.

[0032] When it is necessary to move the L-shaped support plate 3 to spray the fixed shell, the forward and reverse motors 12 are started, and the forward and reverse motors 12 drive the screw 11 to rotate. Since the screw 11 is threadedly connected to the L-shaped support plate 3, and the rotation of the L-shaped support plate 3 is restricted by the limit block and the limit groove, the L-shaped support plate 3 can move on the surface of the screw 11, thereby driving the paint spray tube 4 to spray the surface of the shell.

[0033] The lower surface of the L-shaped support plate 3 is fixedly connected to the paint spray pipe 4 through a connecting rod, and a delivery pipe 5 is fixedly installed inside the paint spray pipe 4. The two ends of the delivery pipe 5 are fixedly connected to the two sides of the inner wall of the paint spray pipe 4.

[0035] Starting the first electric push rod 32 and the second electric push rod 34 can push the blocking block 31 and the blocking ring 33 to move, which is convenient for changing the painting and cleaning length of the paint spray tube 4 and the delivery tube 5, and is convenient for adapting to shells of different widths. In the process of movement, the blocking ring can also scrape and clean the paint adhered to the inner wall of the paint spray tube 4, avoiding clogging of the first connecting tube 6 and the micro nozzle.

[0036] A paint supply assembly for supplying paint to the paint spraying pipe 4 is provided on the top of the L-shaped support plate 3 .

[0037] The paint supply assembly includes a paint storage box 13 fixedly mounted on the L-shaped support plate 3, a pump body 14 fixedly mounted on the paint storage box 13, and an output end of the pump body 14 is connected to the paint spray pipe 4 through a connecting pipe 15.

[0038] When the fixed shell needs to be sprayed, the pump body 14 is started, and the pump body 14 extracts the paint in the paint storage box 13 and transports it to the paint spraying pipe 4 through the connecting pipe 15, and then sprays it out through the first connecting pipe 6 and the micro nozzle.

[0039] A cleaning blowing assembly for providing water or hot air to the delivery pipe 5 is also provided on the top of the L-shaped support plate 3 .

[0040] The cleaning and blowing assembly includes a water tank 16 fixedly mounted on the L-shaped support plate 3, a pump body 17 fixedly mounted on the water tank 16, the output end of the pump body 17 is connected to the delivery pipe 5 through a connecting pipe 18, and a control valve 19 is provided on the connecting pipe 18.

[0041] By arranging the delivery pipe 5 inside the paint spray pipe 4, the delivery pipe 5 plays the role of water supply and air supply, reducing the space occupied by the external arrangement, and facilitating the water supply and cleaning of the surface of the electronic product shell before spraying, that is, opening the control valve 19, closing the control valve 2 23, and starting the pump body 2 17, the pump body 2 17 draws water from the water tank 16, and delivers it to the second connecting pipe 7 through the connecting pipe 2 18, and then sprays it through the micro-sprinkler to clean the surface of the shell, and then close the control valve 19, open the control valve 2 23, and turn on the fan 20 and the heater 21, the external air heated by the heater 21 enters the delivery pipe 5 through the connecting pipe 2 18, and then sprays it through the second connecting pipe 7 and the micro-sprinkler to blow hot air to the cleaned shell surface for drying, thereby ensuring the cleanliness of the shell surface and making the paint surface after spraying more flat and smooth.

[0042] By arranging the delivery pipe 5 inside the paint spraying pipe 4, and staggering the first connecting pipe 6 and the second connecting pipe 7, during the process of spraying the shell, the first connecting pipe 6 and the micro-spray nozzle spray paint on the shell, and opening the control valve 23, with the cooperation of the second connecting pipe 7 and the micro-spray nozzle, the paint surface after spraying can be dried with hot air, thereby accelerating the forming efficiency of the paint surface. In the process of hot air passing through the delivery pipe 5, the surface temperature of the delivery pipe 5 increases, which heats the paint between the paint spraying pipe 4 and the delivery pipe 5, avoiding partial solidification of the paint, and making the paint spraying smoother.

[0043] Two collecting slots 8 are provided in the placement tank, and the two collecting slots 8 are connected with a paint collecting pipe 9. A cavity is provided inside the support platform 1, and a wastewater collecting component that can extend into the collecting slot 8 is slidably provided in the cavity.

A threaded hole is provided on the side of the support platform 1, and a threaded column 25 is threadedly connected to the threaded hole. The end of the threaded column 25 is rotatably connected to the collection frame 24. A water outlet is provided on the collection frame 24, and a sealing assembly for sealing the water outlet is provided on the collection frame 24.

[0045] Before the shell needs to be cleaned, rotate the threaded column 25. Since the threaded column 25 is threadedly connected to the threaded hole, the threaded column 25 can move while rotating. Moreover, since the threaded column 25 is rotatably connected to the collection frame 24, rotating the threaded column 25 can push the collection frame 24 to move, so that the collection frame 24 can be inserted into the collection slot 8, which is convenient for collecting the wastewater generated during the cleaning process. The sealing component seals the water outlet, preventing the wastewater from leaking out during the movement of the collection frame 24.

[0046] The bottom of the inner wall of the collecting frame 24 is tilted, and the tilted bottom of the collecting frame 24 facilitates the wastewater to flow to the water outlet.

[0047] The blocking assembly includes a support rod fixedly mounted on the inner wall of the collection frame 24, a telescopic rod 26 fixedly mounted on the support rod, a sealing plug 27 fixedly connected to the bottom end of the telescopic rod 26, and a spring 28 for pushing the sealing plug 27 downward is sleeved on the telescopic rod 26.

[0048] Under the action of the elastic force of the spring 28, the sealing plug 27 can be pushed downward, so that the sealing plug 27 blocks the water outlet, thereby preventing waste water from flowing out during the movement of the collection frame.

[0049] A wastewater storage frame 29 is fixedly mounted on the support platform 1 . A screw hole is provided at the bottom of the wastewater storage frame 29 , and a bolt 30 is threadedly connected to the screw hole.

[0050] When the wastewater in the collection frame 24 needs to be stored in the wastewater storage frame 29, the bolt 30 is rotated, and the bolt 30 rotates upward, overcoming the elastic force of the spring 28 to push the sealing plug 27 upward, and the sealing plug 27 is separated from the water outlet, so that the wastewater can flow into the wastewater storage frame 29.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
