Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0028] Please refer to the attached Figures 1 to 5 As shown, an automatic powder spraying and painting unit for lamp beads in an embodiment of the present utility model includes a chassis 1. A linear module 8 is fixedly installed inside the chassis 1. An adjusting seat 9 is fixedly connected above the slide table of the linear module 8. A support plate 10 is arranged on the upper end surface of the adjusting seat 9. The support plate 10 is used to place the substrate. By setting the linear module 8 to drive the support plate 10 to enter and exit the spraying area, it is convenient for loading and unloading. At the same time, the linear module 8 is also used to provide freedom in the Y-axis direction. The support plate 10 can reciprocate. Therefore, uniform spraying can be achieved during spraying.

[0029] Above the pallet 10 inside the chassis 1, a bidirectional movement mechanism 6 is fixedly installed. In this embodiment, the bidirectional movement mechanism 6 is used to drive two spraying heads 7 to move towards each other. Specifically, the bidirectional movement mechanism 6 includes a housing 61. Inside the housing 61, a bidirectional lead screw 66 is rotatably connected. On both outer ends of the bidirectional lead screw 66, a moving seat 67 is sleeved. The upper end of the moving seat 67 extends out of the housing 61 and is fixedly connected to a connecting plate 63. On the front faces of the two connecting plates 63, a spraying head 7 is fixedly connected. The moving seats 67 are respectively sleeved on both sides of the bidirectional lead screw 66. When the bidirectional lead screw 66 rotates, the two moving seats 67 can move towards each other, thereby driving the two spraying heads 7 to move away from and close to each other. Among them, the upper end of the moving seat 67 extends out of the housing 61 and is connected to the connecting plate 63, making the lower end face of the housing 61 in a closed state, and it is not easy for powder to enter and affect the operation of the bidirectional lead screw 66.

[0030] The adjusting seat 9 includes a seat body 91. The lower end face of the pallet 10 is slidably connected to the seat body 91. Inside one side of the seat body 91, a second motor 94 is fixedly installed. The output end of the second motor 94 is fixedly connected to a gear 93. The gear 93 is meshed with a rack 92. The rack 92 is fixedly connected to the pallet 10. The adjusting seat 9 in this embodiment is used to drive the pallet 10 to be offset, which is convenient for using a single spraying head 7 to spray powder on the middle position of the substrate. Specifically, the second motor 94 is driven to rotate the gear 93, thereby driving the pallet 10 to move through the rack 92, so that the pallet 10 is adjusted to an offset position, and the middle position of the substrate is adjusted to the sprayable area of a spraying head 7. After that, only this spraying head 7 is used to spray the middle area.

[0031] As an implementation manner of the present utility model, please refer to the attached drawings Figure 3 , 4 As shown, one end of the housing 61 is fixedly connected to a first motor 62. The output end of the first motor 62 is fixedly connected to the bidirectional lead screw 66. Inside the housing 61, guide rods 68 are fixedly connected on both the upper and lower sides of the bidirectional lead screw 66. The moving seat 67 is slidably sleeved on the guide rod 68. The bidirectional lead screw 66 is driven to rotate by the first motor 62, thereby driving the moving seat 67 to move. In order to prevent the moving seat 67 from rotating together with the bidirectional lead screw 66, two guide rods 68 sleeved on the moving seat 67 are provided to restrict the moving seat 67.

[0032] At the same time, in order to ensure the stable movement of the connecting plate 63, in this embodiment, guide rails 65 are fixedly connected to both the upper and lower sides of the front end face of the housing 61. Two sliders 64 are fixedly connected to the rear end of the connecting plate 63. The sliders 64 are slidably connected to the guide rails 65. The connecting plate 63 is restricted by the guide rails 65 and the sliders 64, thereby ensuring the stable movement of the connecting plate 63.

[0033] As an implementation manner of the present utility model, please refer to the attached drawings Figure 5As shown in the figure, two sensors 96 are fixedly connected inside the seat body 91. One end of the rack 92 away from the second motor 94 is fixedly connected with a contact plate 97. The detection ends of the two sensors 96 both face the contact plate 97. The two sensors 96 are both contact sensors. By setting the two sensors 96, the position of the pallet 10 is detected. The two sensors 96 are respectively arranged inside and on the inner wall of the seat body 91. After the pallet 10 is offset in place, the contact plate 97 will trigger the sensor 96 inside the seat body 91, the second motor 94 stops, and the pallet 10 stops. After the pallet 10 is reset, the sensor 96 on the other side is triggered, the second motor 94 stops, and the pallet 10 stops.

[0034] At the same time, to prevent the rack 92 from interfering with the movement of the pallet 10, a through hole 95 is provided at a position corresponding to the rack 92 on the side of the seat body 91 close to the second motor 94. The setting of the through hole 95 leaves space for the rack 92 to enter and exit.

[0035] As an implementation manner of the present utility model, please refer to the attached drawings Figure 2 As shown in the figure, an installation plate 11 is fixedly connected below the linear module 8 inside the chassis 1. A plurality of through holes 12 are provided inside the installation plate 11. A collection tank 2 is slidably arranged below the installation plate 11. A handle 3 is fixedly connected to the outer end of the collection tank 2. The installation plate 11 is provided with through holes 12, and the excess powder will fall into the collection tank 2, which is convenient for recycling and cleaning of the chassis 1.

[0036] As an implementation manner of the present utility model, please refer to the attached drawings Figure 1 As shown in the figure, the upper side of the front end face of the chassis 1 is rotatably connected with a box door 4 through a hinge. An observation window 5 is fixed in the middle of the box door 4. The box door 4 can close the chassis 1 to prevent the powder from spreading. The observation window 5 is made of transparent glass, which is convenient for the staff to timely understand the internal working conditions of the chassis 1

[0037] Working principle: The substrate equipped with LED lamp beads is placed on the pallet 10. The linear module 8 drives the pallet 10 to enter and exit the spraying area; through the setting of the bidirectional moving mechanism 6, the two spraying heads 7 can spray the two sides of the substrate from the outside to the inside at the same time. Compared with the traditional single-side powder spraying method, the powder spraying speed is effectively increased, and the production efficiency is improved; after spraying to the middle area of the substrate, through the setting of the adjusting seat 9, the pallet 10 is offset, and the middle position of the substrate is adjusted to the sprayable area of one spraying head 7, and then only this spraying head 7 is used to spray the remaining area in the middle, so as to complete the powder spraying operation.

[0038] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
