Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1-6 The present invention includes a body 1, with support feet 5 fixedly installed at the four corners of the bottom of the body 1. A connecting shaft 8 is fixedly installed in the inner cavity of the body 1, and an organic cover 7 is rotatably connected to the outer side of the connecting shaft 8. A worktable 4 is fixedly installed on the right side of the organic cover 7, and a sample stage 10 is fixedly installed on the top of the worktable 4. Slide grooves 9 are provided on both sides of the worktable 4. A gel clamping mechanism 3 is installed at the bottom of the worktable 4. An organic cover connecting mechanism 2 is installed in the inner cavity of the body 1 and is connected to the organic cover 7. An organic cover fixing mechanism 6 is installed on the left side of the organic cover 7 and is connected to the body 1.

[0030] In Embodiment Two, based on Embodiment One, the cover connecting mechanism 2 includes two crossbars 201 fixed to the inner cavity of the body 1. A sliding plate 203 is movably mounted on the outer side of the two crossbars 201. Rotating plates 204 are rotatably connected to both sides of the front of the sliding plate 203. A fixed plate 202 is rotatably connected to one side of each rotating plate 204. The left side of the fixed plate 202 is fixedly connected to the right side of the cover 7. An mounting plate 205 is fixedly installed in the inner cavity of the body 1. A crossbar 206 is fixedly installed on the back. One end of the crossbar 206 is fixedly connected to the back of the inner cavity of the machine body 1. A slider 208 is movably installed on the outside of the crossbar 206. A rotating plate 209 is rotatably connected to the left side of the slider 208. The left side of the rotating plate 209 is rotatably connected to the right side of the slide plate 203. A spring 207 is connected to the back of the slider 208. One side of the spring 207 is connected to the back of the inner cavity of the machine body 1. The spring 207 is movably sleeved with the crossbar 206.

[0031] When the control of the cover 7 is released, the originally stretched spring 207 resets, causing the slider 208 to move backward along the crossbar 206. The rotating plate 209 causes the slide plate 203 to move to the left along the two crossbars 201. At this time, the two rotating plates 204 drive the fixed plate 202 to move, and cause the cover 7 to rotate clockwise around the connecting shaft 8. This causes the sample stage 10 to move, so that the sample stage 10 is located outside the body 1. The cutting process can be completed on the sample stage 10, avoiding the exposure of the ultraviolet rays on the body 1.

[0032] In Embodiment 3, based on Embodiment 1, the hood fixing mechanism 6 includes a mounting rod 601 fixed to the left side of the hood 7. A limit block 605 is fixedly connected to the left end of the mounting rod 601. A rotating cylinder 602 is rotatably connected to the outer side of the mounting rod 601. A movable rod 6010 is movably mounted on the inner side of the rotating cylinder 602. A mounting block 604 is fixedly connected to one end of the movable rod 6010. A positioning rod 609 is fixedly connected to one side of the mounting block 604. A spring is connected between the rotating cylinder 602 and the mounting block 604. Spring 3 6011 is movably connected to movable rod 6010. Support plate 606 is fixedly connected to the left side of machine cover 7. The top of support plate 606 is attached to the bottom of rotating cylinder 602. Limit plate 603 is fixedly installed on the front of machine body 1. Rubber pad 608 is fixedly installed on the right side of limit plate 603. The right side of rubber pad 608 is attached to the left side of machine cover 7. Positioning hole 607 is opened on the front of limit plate 603. One end of positioning rod 609 extends to the inside of positioning hole 607.

[0033] When the cover 7 is opened, the left side of the cover 7 is in contact with the right side of the rubber pad 608. First, the mounting block 604 is moved, which drives the positioning rod 609 to move, so that the mounting block 604 is close to the rotating cylinder 602. At this time, the spring 6011 is compressed. Then, the rotating cylinder 602 is rotated through the mounting block 604, so that the mounting block 604 is located in front of the limiting plate 603. Then, the control of the mounting block 604 is released. At this time, the spring 6011 is reset, which drives the mounting block 604 to move away from the rotating cylinder 602, and drives the positioning rod 609 to move until one end of the positioning rod 609 is located inside the positioning hole 607. At this time, the cover 7 is fixed to the limiting plate 603, and the position of the cover 7 is fixed, thereby fixing the position of the sample stage 10 and preventing the cover 7 from shaking when cutting the glue.

[0034] In Example 4, based on Example 1, the gel clamping mechanism 3 includes a bottom rod 301 fixed to the bottom of the worktable 4. A bottom block 308 is fixedly connected to the bottom end of the bottom rod 301. A movable block 3011 is movably installed on the outer side of the bottom block 308. A spring 2 302 is connected between the movable block 3011 and the worktable 4. The spring 2 302 is movably sleeved with the bottom rod 301. Fixed rods 3012 are fixedly connected to the inner sides of the two sliding grooves 9. Movable blocks 1 303 are movably installed on the outer sides of the two fixed rods 3012. Rotating rods 1 304 are rotatably connected to the bottom of the two movable blocks 1 303. The bottom ends of the two rotating rods 1 304 are respectively connected to the movable blocks 3011, ... The two sides of 3011 are rotatably connected. The top of the two movable blocks 303 is fixedly installed with clamping plates 3013. The side of the two clamping plates 3013 that are close to each other is located on the top of the sample stage 10. The two sides of the bottom block 308 are fixedly connected with side rods 307. The two side rods 307 that are far apart from each other are fixedly connected with side blocks 3010. The outer sides of the two side rods 307 are movably installed with movable blocks 306. The bottom of the two movable blocks 306 is fixedly installed with bending rods 309. The top of the two movable blocks 306 is rotatably connected with rotating rods 305. The top of the two rotating rods 305 is rotatably connected to the two sides of the movable block 3011 respectively.

[0035] When cutting the gel, first hold the two bending rods 309 and move them closer together, which in turn moves the two movable blocks 306 closer together. At this time, the two rotating rods 305 move the movable block 3011 upward, while the spring 302 is compressed. Then, the two rotating rods 304 move the two movable blocks 303 away from each other, and the two clamping plates 3013 move away from each other. Then, place the gel on the top of the sample stage 10, so that it is between the two clamping plates 3013. Then release the control of the two bending rods 309. At this time, the spring 302 resets and moves the movable block 3011 downward, which in turn moves the two movable blocks 303 closer together. At the same time, the two clamping plates 3013 move closer together and clamp the gel, thus completing the fixation of the gel, which is convenient for subsequent cutting.
