[0002] The positioning correction structure of the digital spray machine is mainly used to ensure that the product to be sprayed is in the accurate position during the spraying process to achieve high-quality spraying effects.

[0003] In the existing technology, the common digital spray machine positioning and correction structure cannot adapt to the positioning and correction of different models of products to be processed, which means that companies need to invest more money to purchase equipment of various specifications. For example, for a company that produces multiple models of mobile phone cases, if the positioning and correction structure of the digital spray machine can only adapt to a mobile phone case of a specific width, then when mobile phone cases of other widths need to be produced, new positioning and correction equipment must be purchased. Each device has a certain purchase cost, including the price of the equipment itself, transportation costs, installation and debugging costs, etc. As the variety of products increases and the size diversifies, the cost of purchasing equipment will increase exponentially. In order to address this problem, a positioning and correction structure for a digital spray machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-6 A positioning correction structure of a digital sprayer includes a base 1, a mounting frame 2 is installed on the base 1, a spraying assembly is installed on the mounting frame 2, and a moving assembly for moving the spraying assembly is also provided on the mounting frame 2. The above-mentioned components are all existing technology components, which are disclosed in sufficient detail in the prior art. This proposal does not raise any questions about them, so they are not drawn or described in detail.

[0028] A platform 4 is provided on the base 1, a transmission chamber 17 is provided inside the platform 4, two rotating channels 12 are provided on the platform 4, a vertical screw 15 extending into the transmission chamber 17 is rotatably provided on the base 1, and a horizontal screw 13 extending into the transmission chamber 17 is provided in each of the two rotating channels 12. The horizontal screw 13 is connected to the vertical screw 15 through a transmission mechanism, and a power mechanism connected to the vertical screw 15 is provided in the transmission chamber 17. A movable frame 7 is threadedly sleeved on the horizontal screw 13, a connecting rod 10 is provided on the movable frame 7 through a connecting groove, a corner frame 9 is provided on the connecting rod 10, an extrusion groove 21 is provided on the connecting rod 10, a positioning block 22 is provided in the extrusion groove 21 through an extrusion mechanism, a plurality of positioning holes 8 are provided on the movable frame 7, a lifting frame 5 is threadedly sleeved on the vertical screw 15, and a top plate 6 is installed on the lifting frame 5.

[0029] The transmission mechanism includes a driving gear 19 mounted on the vertical screw 15 and a transmission gear 20 mounted on the horizontal screw 13, with the driving gear 19 meshing with the transmission gear 20. As shown in the figure, the driving gear 19 and the transmission gear 20 are both bevel gears, meshing vertically. In this embodiment, the thread orientations of the two horizontal screws 13 need to be set according to their rotation directions to ensure that when the two horizontal screws 13 rotate synchronously, the movable frame 7 moves closer or farther away synchronously.

[0030] The power mechanism includes a drive motor 18 disposed on the inner wall of the transmission chamber 17, and the output shaft of the drive motor 18 is fixedly connected to the end of the vertical screw 15. The drive motor 18 is a common power device.

[0031] The extrusion mechanism includes a spring 23 disposed in the extrusion groove 21, with both ends of the spring 23 elastically connected to the outer wall of the positioning block 22 and the inner wall of the extrusion groove 21. The elastic potential energy provided by the spring 23 realizes the extrusion of the positioning block 22, which can be squeezed into any positioning hole 8.

[0032] A horizontal rod 14 is provided within rotation channel 12. It is parallel to horizontal screw 13 and slides through movable frame 7. A vertical rod 16 is provided on base 1. It is parallel to vertical screw 15 and slides through lifting frame 5. Both horizontal rod 14 and vertical rod 16 act as position limiters, respectively, limiting the position of movable frame 7 and lifting frame 5, preventing them from rotating with horizontal screw 13 and vertical screw 15.

[0033] The corner frame 9 is L-shaped, and the platform 4 is provided with a receiving slot 11 that cooperates with the top plate 6. As shown in the figure, there is a product 3 to be processed above the platform 4, and the product 3 to be processed is a mobile phone case. The corner frame 9 can be located at the corner of the mobile phone case for positioning and correction operations.

[0034] The plurality of positioning holes 8 are evenly spaced, and the spacing between adjacent positioning holes 8 is 1 mm. The adjustment distance of each corner frame 9 relative to the movable frame 7 is 1 mm.

[0035] When the present invention is used, in the initial state, the distance between the movable frame 7 and the corner frame 9 is moderate, and the top plate 6 is not in the receiving groove 11. Then, the product 3 (mobile phone case) to be processed is placed with the mouth facing downward on the movable frame 7 and the corner frame 9, and then the drive motor 18 is started. The drive motor 18 can drive the horizontal screw 13 and the vertical screw 15 to rotate with the help of the driving gear 19 and the transmission gear 20. When the horizontal screw 13 rotates, the movable frame 7 and the corner frame 9 move away and finally contact the inner wall of the product 3 to achieve positioning correction, so that it is stably placed below the spray assembly on the mounting frame 2, waiting for spraying. It should be noted that in this state, the top plate 6 is stored in the receiving groove 11.

[0036] After the spraying process is completed, the drive motor 18 is reversed, so that the movable frame 7 and the corner frame 9 are moved and no longer perform positioning correction operations, and are still gradually approaching. Therefore, at this moment, when the vertical screw 15 rotates, the lifting frame 5 can drive the top plate 6 to rise, lift the product 3 to be processed, and thus separate it from the movable frame 7 and the corner frame 9, making it easier to take out.

[0037] In this solution, the positioning holes 8 corresponding to the positioning blocks 22 can be changed, so that the angle brackets 9 can adjust the distance from the movable bracket 7 to accommodate positioning correction of products 3 to be processed of different widths.

[0038] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
