[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-4This utility model provides an embodiment of a painting device for PCB board shells, including a housing 1, a door 5 on the upper right side of the housing 1, a slide rod 17 between the left and right side walls of the housing 1, a slide cylinder 9 slidably connected to the outer wall of the slide rod 17, multiple crossbars 23 on the front and rear sides of the slide cylinder 9, an electric track 11 fixedly connected to the inner bottom wall of the housing 1, a ring rail 15 fixedly connected to the output end of the electric track 11, the slide rod 17 being located at the center of the ring rail 15, a toothed ring 12 being provided on the inner wall of the ring rail 15, a gear 24 being meshed with the toothed end of the toothed ring 12, a first motor 7 being fixedly connected to one side of the gear 24, a sliding mechanism 6 being fixedly connected to the outer wall of the first motor 7, the outer wall of the ring rail 15 and the sliding mechanism 6 being slidably connected, the gear 24 being located inside the sliding mechanism 6, an adjustment device 8 being provided on the lower side of the sliding mechanism 6, spray cylinders 10 being provided on both sides of the lower side of the adjustment device 8, and a spray pipe 18 being fixedly provided on the upper side of the adjustment device 8.

[0024] In this embodiment, Figure 1 The directions are front, back, left, and right. The adjusting device 8 is used to control the flow and on / off of the paint, as well as to stabilize the pressure of the paint, which is existing technology; the nozzles of the two spray guns 10 are offset at a certain angle towards the center of the ring rail 15, so that paint can be sprayed on the left or right side of the PCB board shell.

[0025] When using this device, open the door 5 and place the PCB board casing on the crossbar 23; move the slide cylinder 9 to directly above the electric track 11 through the sliding connection between the slide cylinder 9 and the slide bar 17; and then move the PCB board casing directly above the electric track 11 through the connection between the crossbar 23 and the slide cylinder 9.

[0026] Paint enters the spray gun 10 through the spray nozzle 18 and the adjusting device 8, initiating the painting operation. The left and right movement of the output end of the electric track 11 drives the ring rail 15 to move left and right inside the housing 1, which in turn drives the sliding mechanism 6, allowing the spray gun 10 to move left and right.

[0027] The connection between the first motor 7 and the sliding mechanism 6 allows the first motor 7 to drive the gear 24 to rotate when driven by its output. Through the meshing of the gear 24 and the gear ring 12, the sliding mechanism 6 moves on the ring rail 15, thereby causing the spray nozzle 10 to move in a circular motion around the center of the ring rail 15. This allows the spray nozzle 10 to spray paint on all sides of the PCB board casing. This improves the situation where manual painting is time-consuming and there are large differences in coating between casings due to different operator skill levels, which can easily lead to uneven coating.

[0028] Reference Figures 1-2A filter box 2 is installed on the upper side of the housing 1, and an exhaust fan 3 is installed on the right side of the filter box 2. An exhaust pipe 4 is installed on the lower side of the exhaust fan 3, and the outer wall of the exhaust pipe 4 passes through the upper side of the housing 1.

[0029] Specifically, after the device is used to paint the PCB board casing, the exhaust fan 3 is started, and the harmful gases and residual particles inside the box 1 are extracted through the exhaust pipe 4 and filtered through the filter box 2, thereby improving the safety and environmental protection of the operation.

[0030] Reference Figure 2 A hanging rod 19 is fixedly connected to the inner left side of the housing 1. The outer wall of the nozzle 18 passes through the left side of the housing 1. Multiple hooks are provided on the upper outer wall of the left end of the nozzle 18. The upper part of the hook of the nozzle 18 is set on the hanging rod 19, and the hook of the nozzle 18 is slidably connected to the outer wall of the hanging rod 19. A first spring is provided on the left end of the hanging rod 19, and the right end of the first spring of the hanging rod 19 is fixedly connected to the rightmost hook of the nozzle 18.

[0031] Specifically, when the spray nozzle 10 moves to the right, it causes the nozzle 18 to stretch. Through the sliding connection between the hook and the hanging rod 19, the hook moves to the right, thereby stretching the nozzle 18. When the spray nozzle 10 moves to the left, the first spring contracts, causing the hook to move to the left, which in turn causes the nozzle 18 to move to the left, thereby retracting the nozzle 18.

[0032] Reference Figure 2 A connecting block 13 is fixedly installed at the output end of the electric track 11, and the upper side of the connecting block 13 is fixedly connected to the lower side of the ring track 15.

[0033] Specifically, the movement of the output end of the electric track 11 drives the movement of the connecting block 13, which in turn drives the movement of the ring track 15, and the stability of the ring track 15 is improved by the connecting block 13.

[0034] Reference Figures 2-3 An electric track 22 is provided between the left and right side walls of the housing 1. The electric track 22 includes a belt, a driven roller and a driving roller wrapped by the belt, and a motor connected to the driving roller. One end of the belt on one side of the electric track 22 is fixedly connected to the slide cylinder 9. One end of the driven roller and belt of the electric track 22 is located on the right side of the housing 1, and the other end of the driving roller, motor and belt of the electric track 22 is located on the right side of the housing 1.

[0035] Specifically, when the PCB board casing is placed on the crossbar 23, the slide cylinder 9 is driven to move left and right by the electric track 22, thereby realizing the left and right movement of the PCB board casing inside the box 1.

[0036] Reference Figure 3The outer wall of the slide rod 17 is fixedly connected to the slide bar 21, and the inner wall of the slide cylinder 9 is provided with a groove. The inner wall of the groove of the slide cylinder 9 and the outer wall of the slide bar 21 are slidably connected.

[0037] Specifically, through the sliding connection between the slider 21 and the groove, the slider 9 can only move left and right on the slider 17, thereby preventing the slider 9 from rotating or shifting with the slider 17 due to the shift of the center of gravity of the PCB board casing, which helps to fix the PCB board casing.

[0038] Reference Figures 2-4 The outer wall of the ring rail 15 is provided with a ring groove 14, and a roller 16 is rotatably connected between the upper left and right side walls of the sliding mechanism 6. The inner wall of the ring groove 14 is fixedly set on the outer wall of the roller 16.

[0039] Specifically, the fixed arrangement of the annular groove 14 and the roller 16 improves the stability of the sliding mechanism 6 moving on the annular rail 15, which helps to improve the efficiency of uniform paint coating.

[0040] Reference Figure 3 Multiple retractable rods 20 are provided on the upper side of the crossbar 23. The outer wall of the retractable rod 20 passes through the upper side of the crossbar 23, and the retractable rod 20 and the crossbar 23 are slidably connected. A second spring is fixedly connected to the lower side of the retractable rod 20, and the lower side of the second spring on the lower side of the retractable rod 20 is fixedly connected to the inside of the crossbar 23.

[0041] Specifically, when the PCB board casing is placed on the crossbar 23, the PCB board casing causes the multiple retractable rods 20 to be subjected to different forces, and at the same time, the retractable rods 20 compress the second spring. Through the sliding connection between the retractable rods 20 and the crossbar 23, the multiple retractable rods 20 retract into the crossbar 23 to different degrees, forming an effect of wrapping the PCB board casing; thus, the PCB board casing is fixed.

[0042] Working principle: When using this device, open the door 5 and place the PCB board shell on the crossbar 23; due to the weight of the PCB board shell itself and its irregular shape, the multiple retractable rods 20 retract into the crossbar 23 to varying degrees, forming an effect of wrapping the PCB board shell; thus, the PCB board shell is fixed.

[0043] Driven by the electric track 22, the slide cylinder 9 moves on the slide rod 17; and through the sliding connection between the slide bar 21 and the groove on the slide cylinder 9, the PCB board shell can move stably left and right inside the box 1 and move to directly above the electric track 11.

[0044] During spraying, paint enters the spray nozzle 10 through the spray pipe 18 and the adjusting device 8. The left and right movement of the output end of the electric track 11 drives the connecting block 13 to move, which in turn drives the ring rail 15 to move, thereby driving the sliding mechanism 6 to move, so that the spray nozzle 10 moves left and right; thus realizing the spraying of paint on the PCB board shell in the left and right direction.

[0045] With the fixed arrangement of the annular groove 14 and the roller 16, the gear 24 is driven to rotate by the output of the first motor 7. Through the meshing of the gear 24 and the gear ring 12, the sliding mechanism 6 is driven to move on the ring rail 15, thereby driving the spray nozzle 10 to make a circular motion around the PCB board shell, so that the spray nozzle 10 can spray paint on the side and bottom of the PCB board shell.

[0046] When using this device to perform PCB board casing work, the exhaust fan 3 is started, and harmful gases and residual particles inside the casing 1 are extracted through the exhaust pipe 4 and filtered through the filter box 2. This improves the situation where manual painting is time-consuming and there are large differences in coating between casings due to different operator skill levels, which can easily lead to uneven coating.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
