DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0026] refer to Figure 1-5 An embodiment of the present application shows an elliptical printing machine with precise visual positioning of a screen, including an elliptical track 1, a print head 2 and a screen (not shown), and also includes a beam 4 slidably arranged on the elliptical track 1, a table 3 arranged on the beam 4, and at least two visual components 5 arranged at the bottom of the table 3; a light-through hole 31 corresponding to the position of the visual component 5 is provided on the table 3, at least one visual component 5 is slidably arranged at the bottom of the table 3, and the light-through hole 31 corresponding to the sliding visual component 5 is a strip hole, and the length direction of the strip hole is arranged corresponding to the sliding direction of the visual component 5.

[0027] Specifically, the visual components 5 are configured as at least two. When the platen 3 moves to the bottom of the screen, the visual component 5 shoots the screen. The marking points are pre-set on the screen. The marking points correspond to the visual components 5 one by one. By shooting the identification points for identification and comparison, it is determined whether the position of the screen deviates from the pre-set position, and then calibration is performed. When the size of the screen is small, some of the visual components 5 are located outside the projection range of the screen, and the identification points on the screen cannot correspond to the positions of the visual components 5; at this time, the position of the visual components 5 at the bottom of the platen 3 can be adjusted so that all the visual components 5 are located within the projection range of the screen, and the positions of the visual components 5 and the identification points on the screen correspond to each other, so as to realize the identification detection of the identification points.

[0028] It is understandable that the number of the visual components 5 can be two, three or more. Figure 3 As shown, in this embodiment, two visual components 5 are provided, wherein one visual component 5 is fixed at the bottom of the table 3, and the other visual component 5 is slidably provided at the bottom of the table 3; of course, both visual components 5 may also be slidably provided at the bottom of the table 3.

[0029] Specifically, the visual component 5 includes a first mounting frame 51, on which a light source 52, a lens 53 and an industrial camera 54 are arranged. The light source 52 is a rotating coaxial light source 52; when the visual component 5 is fixed to the bottom of the table 3, the first mounting frame 51 is connected to the table 3 to achieve fixation.

[0030] In some embodiments, to achieve stable sliding of the visual component 5, refer to Figure 3-5 A movable guide mechanism 32 is provided at the bottom of the table 3, and the movable guide mechanism 32 includes a slide rail 321 arranged at the bottom of the table 3, a slider 324 slidably connected to the slide rail 321, and a second mounting frame 325 connected to the slider 324; the first mounting frame 51 slidably arranged on the visual component 5 at the bottom of the table 3 is connected to the second mounting frame 325.

[0031] Among them, through the guidance of the slide rail 321, the slider 324 can slide stably along the slide rail 321, thereby driving the second mounting frame 325 and the visual component 5 to move along the slide rail 321; after the visual component 5 adjusts its position, since the light hole 31 is a bar, the visual component 5 can always perform shooting and recognition.

[0032] Preferably, reference Figure 4 Two connecting blocks 322 are provided at the bottom of the table 3, a support plate 323 is provided between the two connecting blocks 322, a slide rail 321 is provided above the support plate 323, and a slider 324 is slidably provided above the slide rail 321. In this way, the support plate 323 and the slide rail 321 can support the slider 324, the second mounting frame 325 and the visual component 5 from bottom to top, and the force is more stable, so that the visual component 5 can slide more reliably.

[0033] In some embodiments, Figure 2 and Figure 5 As shown, a positioning block 326 is provided on the second mounting frame 325, and the positioning block 326 is located on the side of the support plate 323. A positioning hole 3261 is provided on the positioning block 326, and a locking member is threadedly connected to the positioning hole 3261. The locking member (not shown) abuts against the side of the support plate 323 to fix the second mounting frame 325 on the slide rail 321.

[0034] Specifically, after the position adjustment of the visual component 5 is completed, the locking member can be rotated, and the locking member moves along the axial direction of the positioning hole 3261 until the locking member abuts against the side of the support plate 323, and the locking member squeezes the support plate 323 to achieve the position fixation of the visual component 5 on the slide rail 321; similarly, when the visual component 5 needs to be moved, the locking member can be rotated first to separate the locking member from the support plate 323, and the movement of the visual component 5 can be achieved. In addition, for ease of manufacturing, the locking member can be a bolt.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
