For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0020] Please refer to Figures 1-10 , the present invention provides a technical solution: a carrier for accommodating photosensitive resin, including a resin tank 1, a carrier film 2, several groups of upper fixing mechanisms 3 and four groups of lower fixing mechanisms 4.

[0021] The outer side of the top edge of the resin tank 1 is fixedly connected with an upper outer edge 5, and four groups of vertical grooves 51 are regularly and matrix-penetratedly opened inside the upper outer edge 5.

[0022] The carrier film 2 is connected to the resin tank 1.

[0023] The carrier film 2 includes a lower bagging part 21 and four groups of edge clamping parts 22, where: The lower film bagging part 21 is connected to the inner wall of the resin tank 1; Four groups of edge clamping parts 22 are integrally connected to the top edges of the lower film bagging part 21, and the four groups of edge clamping parts 22 are respectively connected to the four vertical grooves 51.

[0024] Specifically, by setting the lower film bagging part 21 and the edge clamping parts 22 of the carrier film 2, the resin tank 1 can be isolated from the resin, preventing the resin from directly contacting the inner wall of the resin tank 1, thereby reducing the pollution and wear of the resin tank 1 and extending the service life of the resin tank 1.

[0025] The upper fixing mechanism 3 is arranged inside the upper outer edge 5, and the upper fixing mechanism 3 is suitable for fixing the upper part of the carrier film 2.

[0026] The upper fixing mechanism 3 includes an inner groove 31, a dial 32, a spring 33, several groups of pressing pads 34, a hanging sleeve 35 and a positioning rod 36, where: The inner groove 31 is opened at the bottom inside the upper outer edge 5, and the inner groove 31 is communicated with the vertical groove 51; The dial 32 is movably connected inside the inner groove 31, and the bottom of the dial 32 extends below the bottom of the upper outer edge 5; The spring 33 is fixedly connected between the inner wall of the inner groove 31 and the surface of the dial 32; Several groups of pressing pads 34 are fixedly connected to the side of the dial 32 far from the spring 33 in a regular matrix; The hanging sleeve 35 is fixedly connected to the inner top of the inner groove 31; One end of the positioning rod 36 is fixedly connected to the dial 32, and the positioning rod 36 is inserted into the inner side of the hanging sleeve 35 with a clearance fit.

[0027] Specifically, the pressing pad 34 is made of rubber material. By setting the inner groove 31, the dial 32, the spring 33, the pressing pad 34, the hanging sleeve 35 and the positioning rod 36 of the upper fixing mechanism 3, the edge clamping part 22 can be firmly fixed inside the upper outer edge 5 of the resin tank 1 by the spring force and the pressing pad 34, ensuring the stability and flatness during the printing process.

[0028] The length of the dial 32 is adapted to the width of the lower end of the inner groove 31. Specifically, the lower end of the inner groove 31 positions the dial 32. The dial 32 is of a cuboid structure, which allows the dial 32 to slide freely inside the inner groove 31. The user can control the movement of the dial 32 by operating outside the upper outer edge 5, thereby controlling the separation of the pressing pad 34 from the edge clamping part 22, facilitating the adjustment of the tension of the carrier film 2, preventing the carrier film 2 from being slack or too tight, and also facilitating the installation and disassembly of the carrier film 2.

[0029] Specifically, after the paddle 32 is pulled outward, the spring 33 is in a compressed state, and the edge clamping portion 22 can be disassembled at this time, and then the spring 33 can drive the paddle 32 and the pressure pad 34 to return to their original position without manual adjustment.

[0030] Four groups of lower fixing mechanisms 4 are respectively arranged at the lower corners of the resin tank 1 , and the lower fixing mechanisms 4 are suitable for fixing the lower part of the supporting film 2 .

[0031] The lower fixing mechanism 4 includes an inner groove 41, a first outer inclined groove 42, an inner magnetic bead 43, a second outer inclined groove 44, an outer patch 45, an insert block 46, an outer magnetic bead 47 and a connecting rod 48, wherein: The inner groove 41 is formed at the inner bottom corner of the resin tank 1; The first outer inclined groove 42 and the second outer inclined groove 44 are provided at the outer bottom corners of the resin tank 1; The inner magnetic bead 43 is connected to the inner groove 41; The external patch 45 is connected to the outer bottom surface of the resin tank 1; The plug block 46 is fixedly connected to the upper end of the outer patch 45 , and the plug block 46 is plugged into the first outer inclined groove 42 ; The outer magnetic bead 47 is movably connected in the second outer inclined groove 44; The connecting rod 48 is fixedly connected between the insert block 46 and the outer magnetic bead 47 .

[0032] Specifically, by setting the inner groove 41, the first outer inclined groove 42, the inner magnetic bead 43, the second outer inclined groove 44, the outer patch 45, the plug 46, the outer magnetic bead 47 and the connecting rod 48 of the lower fixing mechanism 4, through the magnetic force between the inner magnetic bead 43 and the outer magnetic bead 47, on the one hand, the inner magnetic bead 43 and the outer magnetic bead 47 can be respectively fixed in the inner groove 41 and the second outer inclined groove 44, and on the other hand, the magnetic force can be used to firmly fix the lower part of the supporting film 2 at the lower corners of the resin tank 1, and it is also convenient for disassembly and replacement.

[0033] The inner magnetic beads 43 and the outer magnetic beads 47 are magnetically connected, and the lower pocket portion 21 is disposed between the inner magnetic beads 43 and the inner wall surface of the inner groove 41. Specifically, by arranging the inner magnetic beads 43 and the outer magnetic beads 47 to be magnetically connected, the fixing force of the lower portion of the carrier film 2 can be enhanced to prevent the lower portion of the carrier film 2 from moving or deforming during the printing process.

[0034] The first outer inclined groove 42 and the insert block 46 are both inclined, and the insert block 46 is adapted to the shape of the first outer inclined groove 42. Specifically, the insert block 46 can slide freely in the first outer inclined groove 42, which is convenient for adjusting the tension of the supporting film 2 and preventing the supporting film 2 from being loosened or too tight. At the same time, the inclined insert block 46 is not easy to be separated from the first outer inclined groove 42, thereby improving stability.

[0035] The second outer inclined groove 44 is inclined at the same angle as the first outer inclined groove 42. The width of the upper end of the second outer inclined groove 44 is adapted to the diameter length of the outer magnetic bead 47, and the inscribed length of the lower end of the second outer inclined groove 44 is adapted to the diameter length of the outer magnetic bead 47. Specifically, the upper end of the second outer inclined groove 44 is a cylindrical structure, the lower end of the second outer inclined groove 44 is a hemispherical structure, and the second outer inclined groove 44 has a positioning effect on the outer magnetic bead 47. Under the action of the self-gravity of the outer magnetic bead 47 and the magnetic force of the inner magnetic bead 43, the outer magnetic bead 47 can be stably connected to the inner bottom of the second outer inclined groove 44.

[0036] Specifically, when installing the carrier film 2, first, the lower bagging part 21 of the carrier film 2 is sleeved into the resin tank 1 so that it fits closely with the inner wall of the resin tank 1. Then, the four groups of inner magnetic beads 43 are respectively connected to the four groups of inner grooves 41. The edge clamping parts 22 of the carrier film 2 are respectively inserted into the four groups of vertical grooves 51 in the upper outer edge 5, and the edge clamping parts 22 are tightly attached to the inner walls of the vertical grooves 51 through the upper fixing mechanism 3. Then, the lower fixing mechanism 4 is installed. During the process that the insertion block 46 is obliquely inserted downward into the first outer inclined groove 42, the outer magnetic bead 47 enters the inner bottom of the second outer inclined groove 44, so that the outer magnetic bead 47 and the inner magnetic bead 43 are magnetically attracted to each other. At the same time, the lower bagging part 21 of the carrier film 2 is tightly pressed into the inner groove 41. Then, check whether the carrier film 2 is evenly fixed to the upper and lower ends of the resin tank 1 and whether there is any slack or excessive tightness. If so, the tension of the carrier film 2 can be adjusted by adjusting the positions of the adjusting piece 32 and the outer magnetic bead 47. Finally, the photosensitive resin is poured into the lower bagging part 21. Through the filling of the photosensitive resin, the lower bagging part 21 is tightly pressed against the inner wall surface of the resin tank 1.

[0037] Specifically, when disassembling the carrier film 2, first, the outer patch 45, the insertion block 46, and the outer magnetic bead 47 of the lower fixing mechanism 4 are synchronously pulled obliquely upward to separate them from the resin tank 1. Then, the adjusting piece 32 of the upper fixing mechanism 3 is pulled outward so that the pressing pad 34 is separated from the edge clamping part 22. The edge clamping parts 22 of the carrier film 2 are withdrawn from the four groups of vertical grooves 51. Then, the inner magnetic beads 43 are separated from the inner grooves 41. At the same time, the lower bagging part 21 of the carrier film 2 is separated from the resin tank 1, and the lower bagging part 21 of the carrier film 2 is taken out of the resin tank 1 to complete the disassembly.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
