A sliding device is provided on the upper end of the cover plate 3.

[0029] The sliding device includes a moving groove 31 on the upper end of the cover plate 3, a slider 32 slidably connected to the inner wall of the moving groove 31, a plurality of mounting grooves 33 on the upper end of the slider 32, the plurality of mounting grooves 33 being symmetrically arranged, a placement groove 261 on the upper end of the sliding plate 26, a suction block 262 being provided inside the placement groove 261, the suction block 262 being a strong permanent magnet, the slider 32 being made of ferrous metal material, the suction block 262 and the slider 32 being attracted to each other, the sliding plate 26 abutting against the bottom of the cover plate 3, the sliding device being provided so that when the lead screw 23 rotates, the sliding plate 26 can move, thereby driving the slider 32 to move, thus completing the horizontal movement of the slider 32.

[0030] The adsorption device includes an adsorption tank 4 formed on the inner wall of the sliding groove 11. A movable block 41 is slidably connected to the inner wall of the adsorption tank 4. One end of the movable block 41 is welded to a return spring 42, and the other end of the return spring 42 is welded to the side wall of the adsorption tank 4. A storage cavity is formed on the side wall of the movable block 41, and an electromagnet 43 is placed inside the storage cavity. A rectangular groove 5 is formed on the side wall of the cover plate 3, and an attraction block 51 is welded inside the rectangular groove 5. The attraction block 51 is made of ferrous metal. The rectangular groove 5 corresponds to the adsorption tank 4. A through groove 44 is formed on the side wall of the storage cavity, and a first wire outlet groove 45 is formed on the side wall of the adsorption tank 4. The first wire outlet groove 45 is "L" shaped and communicates with the outside. The conduction line of the electromagnet 43 communicates with the outside through the through groove 44 and the first wire outlet groove 45. The adsorption device is set so that when the cover plate 3 and the rectangular block 1 are against each other, the attraction block 51 and the movable block 41 can be attracted, thereby ensuring the stability of the cover plate 3.

[0031] The positioning device includes a positioning groove 6 formed in the inner wall of the sliding groove 11. A locking block 61 is slidably connected to the inner wall of the positioning groove 6. The side wall of the locking block 61 is welded to one end of a horizontal spring 62, and the other end of the horizontal spring 62 is welded to the inner side wall of the positioning groove 6. A vertical groove 63 is formed through the top of the positioning groove 6, and a push plate 64 is slidably connected to the inner wall of the vertical groove 63. The push plate 64 is welded to the upper end of the locking block 61. A locking groove 65 is formed in the side wall of the cover plate 3, which corresponds to the positioning groove 6 and is slidably connected to the locking block 61. The inner side wall of the slot 6 is welded with a sensing block 7, which is located inside the horizontal spring 62. The locking block 61 and the sensing block 7 are connected to the opening and closing circuit of the electromagnet 43 through the wire. The inner top of the slot 6 is provided with a second wire outlet groove 71. The connecting wire between the locking block 61 and the sensing block 7 is connected to the outside through the second wire outlet groove 71. The locking device makes the cover plate 3 easy to install and remove. When the module needs to be repaired, it can facilitate disassembly and reduce the time consumed by installation and disassembly.

[0032] Multiple first guide rods 8 are welded to the inner wall of the moving groove 31. The multiple first guide rods 8 are symmetrically arranged and are slidably connected to the slider 32. Two symmetrically arranged second guide rods 81 are welded to the inner wall of the sliding groove 11. The second guide rods 81 are slidably connected to the sliding plate 26. The arrangement of the first guide rods 8 and the second guide rods 81 can make the movement of the sliding plate 26 and the slider 32 more stable, so that the stepper motor can make the module move stably.

[0033] In this invention, during installation, the positions of the slot 65 and the block 61 are first aligned. Then, the push plates 64 at both ends are pushed simultaneously to allow the block 61 to move along the slot 6 until it is fully inside. At this point, the block 61 will contact the sensing block 7, causing the electromagnet 43 inside the moving block 41 to be de-energized. Then, the cover plate 3 is pressed down along the sliding groove 11 until it completely blocks the upper end of the sliding groove 11. At this point, the block 61 will move towards the slot 65 under the action of the horizontal spring 62 until it reaches the slot 65, thus enabling the rectangular block 1 and the cover plate 3 to be locked together. When the block 61 is separated from the sensing block 7, the electromagnet 43 inside the moving block 41 will be energized, attracting the attraction block 51 inside the rectangular groove 5, causing the moving block 41 to contact the attraction block 51. This ensures the stability of the cover plate 3, preventing it from shifting and ensuring the secure installation.

[0034] When the module is needed, the object to be moved needs to be placed on the upper end of the slider 32 and connected to the slider 32 through the mounting groove 33. Then, the drive motor 21, which is a stepper motor, is started so that the lead screw 23 can rotate. The sliding plate 26 abuts against the inner wall of the sliding groove 11, so that the lead screw 23 will drive the sliding plate 26 to slide along the second guide rod 82 during the rotation. The second guide rod 82 is set to ensure the stability of the sliding plate 26.

[0035] The sliding plate 26 has a strong magnetic block 262 inside, which will drive the slider 32 made of metal material at the upper end of the cover plate 3 to move. The slider 32 will slide along the first guide rod 8, thus realizing reciprocating motion. The cover plate 3 can keep the module in a closed state when it is working, so that dust and other debris will not enter the module and affect the movement accuracy of the module.

[0036] When it is necessary to replace or repair the internal parts of the module, simply push the push plates 64 at both ends to allow the locking block 61 to enter the locking slot 6 along the locking groove 65, thereby releasing the locking relationship between the locking block 61 and the locking groove 65. When the locking block 61 contacts the sensing block 7, the electromagnet inside the moving block 41 is de-energized, causing the moving block 41 to return to its original position under the action of the return spring 42. This releases the attraction relationship between the attraction block 51 and the electromagnet 43, making it easier to remove the cover plate 3. This effectively reduces the time required for installation and disassembly, thus improving work efficiency.

[0037] 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 within the protection scope of the present invention.
