Description

Technical Field

[0001] The utility model relates to the technical field of plate positioning, in particular to a positioning device for spraying pine boards. Background Art

[0002] In order to prevent wood from being oxidized by air, protect wood from moisture volatilization and the effects of thermal expansion and contraction, and improve the aesthetics and durability of wood, before making furniture, etc. from pine boards, varnish is usually sprayed on the surface. When spraying, it is usually necessary to position the plate to avoid shaking during spraying, so as to ensure that the paint can evenly cover the surface of the wood board, improve the spraying quality, and reduce the occurrence of phenomena such as sagging or orange peel.

[0003] Currently, when positioning a plate, a fixture is usually used to clamp the plate. However, the fixture blocks the path of the paint spraying, which may cause uneven spraying in some areas or failure to cover, resulting in incomplete spraying at the part where the fixture contacts the pine board and requiring subsequent rework.

[0004] Based on the above situation, we propose a positioning device for spraying pine boards to solve the above problems. Summary of the Utility Model

[0005] The utility model provides a positioning device for spraying pine boards to solve the problem of incomplete spraying at the clamped part of the plate caused by clamping the plate with a fixture in the prior art.

The positioning unit is arranged inside the side frames and the bottom frame, and the positioning unit includes a moving seat slidably connected to the inside of the positioning frame and a telescopic connecting member arranged on the moving seat. The movable end of the telescopic connecting member is rotatably connected with a contact sphere, and the plate is clamped by the point contact between the contact sphere and the side wall of the plate. The driving member is arranged inside the positioning frame and is used to drive the moving seat to drive the contact sphere to change the contact position on the side wall of the plate.

[0008] Preferably, the movable end of the telescopic connecting member is provided with a connecting shaft passing through the contact sphere and rotatably connected with the contact sphere, and the axial direction of the connecting shaft is parallel to the thickness direction of the plate to be positioned.

Detailed implementation mode

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific illustrations.

[0023] Refer to Figures 1 - 6 As shown in the figure, a positioning device for spraying pine boards includes a positioning frame 1 and a positioning unit. The positioning unit is arranged inside the side frame 11 and the bottom frame 12. The positioning frame 1 includes at least two side frames 11 and a bottom frame 12. The two side frames 11 are connected to both ends of the bottom frame 12. The positioning unit inside the bottom frame 12 can be used to support the bottom of the board, and the positioning units inside the two side frames 11 can be used to clamp both sides of the board to keep the board standing. When in use, the device can be placed in a paint spraying room or other places for use, which is convenient for full - range spraying treatment;

[0024] Specifically, refer to Figure 4 As shown in the figure, the positioning unit includes a moving seat 2 slidably connected inside the positioning frame 1 and a telescopic connecting piece 21 arranged on the moving seat 2. The movable end of the telescopic connecting piece 21 is rotatably connected with a contact sphere 22. The telescopic connecting piece 21 can adopt structures such as an electric telescopic rod. After placing the board to be sprayed in the positioning frame 1, the telescopic connecting piece 21 is used to drive the contact sphere 22 to move towards the side wall of the board. The contact sphere 22 inside the side frame 11 contacts the side wall of the board to clamp the board, and the contact sphere 22 inside the bottom frame 12 contacts the bottom side wall of the board, which can be used to support the board and lift the board to a certain height, facilitating spraying the bottom side wall of the board and improving the stability during board positioning. By contacting the side wall of the board with the contact sphere 22, point - contact with the board is realized, minimizing the shielding of the spraying by the clamping part.

[0025] Furthermore, in order to spray the position of the contact part between the contact sphere 22 and the clamping part of the board body, a driving piece 3 is also arranged inside the positioning frame 1, which is used to drive the moving seat 2 to drive the contact sphere 22 to change the contact position on the side wall of the board. After the position of the contact sphere 22 changes, the original contact part between the contact sphere 22 and the board is sprayed again to improve the spraying uniformity.

[0026] Among them, in order to improve the clamping and positioning effect, the number of moving seats 2 in the side frame 11 and the bottom frame 12 is at least two groups, and the driving member 3 adopts a bidirectional telescopic mechanism, such as a bidirectional electric telescopic rod or two electric telescopic rods with opposite moving ends, etc., to drive the two groups of moving seats 2 to move in the opposite direction, so as to realize multi-point clamping of the side of the plate, and it is also applicable to positioning plates with different lengths or widths.

[0027] Furthermore, a connecting shaft 4 that penetrates through the contact sphere 22 and is rotatably connected to the contact sphere 22 is provided at the movable end of the telescopic connecting member 21, and the axial direction of the connecting shaft 4 is parallel to the thickness direction of the plate to be positioned, so that the contact sphere 22 can only rotate along the direction of the connecting shaft 4. For example, Figure 3 as shown, when the plate is in a standing state, the movement of the plate in the up and down direction will drive the contact sphere 22 in the side frame 11 to rotate around the connecting shaft 4, and when the moving seat 2 in the side frame 11 and the bottom frame 12 drives the contact sphere 22 to move, it will also rotate around the connecting shaft 4. When the clamped plate moves forward or backward, the contact sphere 22 will not be driven to rotate at this time. If there is movement, it indicates that the external force received by the plate is greater than the friction force between the contact sphere 22 and the plate. When normally spraying the plate, no force needs to be applied to the plate. In the normal clamping state, the plate can be positioned by the contact between the contact sphere 22 and the plate.

[0028] Furthermore, referring to Figure 6 as shown, an elastic friction layer 5 is provided on the outer surface of the contact sphere 22. The elastic friction layer 5 can be made of elastic materials such as rubber or silica gel, etc., to increase the friction force between the contact sphere 22 and the side wall of the plate, making its clamping stability better, and can also protect the side wall of the plate to avoid abrasion of the side wall of the plate during clamping.

[0029] Among them, a reserved groove 6 is provided on the bottom frame 12. The reserved groove 6 can be located in the middle of the positioning frame 1, and is used for preliminary positioning of the plate placed in the positioning frame 1, that is, on the same longitudinal section as the contact sphere 22. When positioning the plate, the plate can be first placed in the reserved groove 6, and then after starting the movable telescopic members in the two side frames 11 to drive the contact sphere 22 to contact and clamp the side wall of the plate, the telescopic connecting member 21 in the bottom frame 12 is used to drive the contact sphere 22 to support the plate to a certain height. In the initial state, the telescopic connecting member 21 in the bottom frame 12 drives the contact sphere 22 to be located inside the bottom frame 12, so that the plate can be stably placed in the reserved groove 6.

[0030] Furthermore, the bottom of the positioning frame 1 is rotatably connected to a base 7, and a motor 71 is provided on the base 7. The output end of the motor 71 is connected to the positioning frame 1 for driving the positioning frame 1 to rotate. The motor 71 drives the positioning frame 1 to drive the clamped plate to rotate slowly and at a uniform speed, so as to perform all-round spraying treatment on the plate, while also avoiding throwing off the clamped plate.
