DETAILED DESCRIPTION

[0030] The present invention is further described in detail below with reference to the embodiments:

[0031] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] like Figures 1 to 5As shown, a modular silk screen fixture can support a workpiece 100, and the workpiece 100 is hollow inside and includes: a base 1; a support seat 2, the support seat 2 is arranged on the upper side of the base 1, and the support seat 2 is connected to a bottom plate 3; a first support member 4, arranged on the front side of the bottom plate 3, and the top surface of the first support member 4 is provided with a first positioning portion 41 that can position the front side of the lower frame 101 of the workpiece 100; a second support member 5, arranged on the rear side of the bottom plate 3 and corresponding to the first support member, and the top surface of the second support member is provided with a lower frame 101 that can position the workpiece 100 01, the second positioning part 51 on the rear side, the height of the first support part 4 is higher than the second support part 5, so that the workpiece 100 is in an inclined state when positioned on the first support part 4 and the second support part 5; the third support part 6 is arranged on the left side of the base plate 3, and the third support part 6 is provided with a first supporting surface 61 that can be pressed against the inner side surface of the workpiece 100; the fourth support part 7 is arranged on the right side of the base plate 3, and the fourth support part 7 is provided with a second supporting surface 71 that can be pressed against the inner side surface of the workpiece 100, and the fourth support part 7 is arranged corresponding to the third support part 6.

[0033] When the present invention is in use, the lower frame 101 of the workpiece 100 is directed toward the base plate 3, and then the front side of the lower frame 101 is aligned with the first positioning portion 41, and the rear side of the lower frame 101 is aligned with the second positioning portion 51, and then ensure that the first top support surface 61 and the second top support surface 71 are located inside the workpiece 100, and then move the workpiece 100 downward so that the front and rear sides of the lower frame 101 of the workpiece 100 are positioned on the first positioning portion 41 and the second positioning portion 51, and the third support component 6 and the fourth support component 7 are extended into the workpiece 100 so that the first top support surface 61 and the second top support surface 71 are against the left side of the inner wall of the workpiece 100 and the right side of the inner wall of the workpiece 100, thereby clamping the workpiece 100 in position to prevent the workpiece 100 from shaking.

[0034] The third supporting member 6 and the fourth supporting member 7 are detachably connected to the base plate 3 , and the third supporting member 6 and the fourth supporting member 7 of different sizes can be replaced to adapt to workpieces of different widths, thus having a wider range of uses.

[0035] The first and second positioning portions 41, 51 are first and second positioning grooves that adapt to the outer shape of the lower frame 101 of the workpiece 100. The provision of the first and second positioning grooves allows the lower frame 101 of the workpiece 100 to be securely positioned and clamped between the first and second support members 4, 5, preventing any looseness. Of course, the second support member 5 can be mounted to the base plate 3 via screws and can be replaced as needed. The second positioning portion 51 can accommodate various contours, such as arcs or squares.

[0036] The first support member 4 includes a first support plate 42 connected to the front side of the base plate 3. A second, laterally arranged, second support plate 43 is connected to the first support plate 42. The first positioning portion 41 is disposed on the second support plate 43. This arrangement allows the upper portion of the workpiece 100 to be tilted, facilitating that the area to be processed 102 faces upward. The first support plate 42 is detachably mounted to the second support plate 43 via screws, achieving modular changes.

[0037] The bottom plate 3 is also provided with a second support column 8 capable of supporting the second support plate 43. Since the first support component 4 is the main force-bearing area during screen printing, the second support column 8 is provided to facilitate supporting the second support plate 43, prevent the second support plate 43 from shaking, and provide a better support effect.

[0038] The first supporting surface 61 and the second supporting surface 71 are arc surfaces provided on the third supporting component 6 and the fourth supporting component 7 and capable of supporting the inner side of the workpiece 100, so that the inner side of the workpiece 100 can be more stable when supporting the first supporting surface 61 and the second supporting surface 71, thereby preventing the workpiece 100 from shaking and reducing defective products.

[0039] The bottom plate 3 is provided with a vertically arranged connecting plate 91, to which a rotating member 92 is connected that can rotate relative thereto. The rotating member is hollow, and when the workpiece 100 is supported on the first support member 4, the second support member 5, the third support member 6, and the fourth support member 7, the side edges of the lower frame 101 of the workpiece 100 can be supported by the rotating member 92. The provision of the rotating member 92 can support the side edges of the lower frame 101 of the workpiece 100, thereby achieving a better support effect and preventing the lower end of the workpiece 100 from shaking.

[0040] The third supporting member 6 is arranged in the accommodating space 921 of the rotating member. Such an arrangement can make the structure more compact and also facilitate positioning and installation.

[0041] A plurality of connecting posts 93 are provided on one side of the base plate 3. A connecting frame 94 is provided on the connecting posts 93. A screen printing frame 95 is rotatably connected to the connecting frame 94. A flexible screen printing unit 96 is provided within the screen printing frame 95. The flexible screen printing unit 96 is made of a film with a pattern, and the pattern is screen-printed on the workpiece 100 using a screen printing roller brush.

[0042] The other side of the bottom plate 3 is provided with a support column 97 that can support the free end of the screen printing frame 95. The support column 97 can prevent the screen printing frame 95 from shaking during screen printing, and the support is more stable.

[0043] A positioning post 98 is further provided in the middle of the base plate, to which a positioning protrusion 99 is detachably connected. The positioning protrusion 99 can be snapped into a positioning groove 102 on the workpiece 100. The setting of the protrusion 99 can locate the hollow part of the workpiece 100, making the workpiece 100 more firmly positioned.

[0044] The connecting column 93 and the supporting column 97 are detachably connected to the bottom plate 3 for easy installation and removal.

[0045] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
