[0019] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The present invention provides a fixing device for transporting a negative electrode of a carbon dioxide laser through improvement. The technical solution of the present invention is: like Figures 1 to 8 As shown, an embodiment of the present invention provides a fixing device for transporting a negative electrode of a carbon dioxide laser, comprising a tray 1, a surface of the tray 1 being provided with a plurality of receiving slots 3, each of which being provided with a clamping structure; The clamping structure includes two empty shells 15 and a base 21. The base 21 is fixed in the corresponding receiving groove 3. The outer side of the base 21 is provided with a centering mechanism for bringing the two empty shells 15 closer together. The inner side of the hollow shell 15 is filled and fixed with a soft body 1 24 , and the top of the base 21 is embedded and fixed with a soft body 2 25 ; Both the soft body 1 24 and the soft body 2 25 are composed of a sealed flexible bag and a fluid with a higher viscosity. The fluid with a higher viscosity is filled into the sealed flexible bag, and then the air in the sealed flexible bag is extracted. From the above connection relationship, it can be seen that the clamping structure adopts a soft wrapping design, that is, the negative electrode is placed in a soft material, and then the soft material wraps the entire negative electrode. The soft material can be deformed according to the outer contour of the negative electrode, so as to better achieve fixation. It can wrap and clamp negative electrodes of various specifications without the need for customized fixtures. At the same time, the sealed fixation form can prevent external damage.

[0021] Specifically, in conjunction with Figure 1 and attached Figure 2 As shown, vertically arranged pins 2 are fixed at the four corners of the tray 1, and sockets 4 adapted to the pins 2 are provided at the four corners of the bottom of the tray 1; It can be seen from the above connection relationship that the arrangement of the pins 2 and the sockets 4 is to facilitate the positioning and stacking of the pallet 1 and to facilitate palletizing.

[0022] Specifically, in conjunction with Figure 1 As shown, the top edge of the plug post 2 is chamfered; From the above connection relationship, it can be seen that the chamfering process is to facilitate the insertion of the column 2 into the socket 4.

[0023] Specifically, in conjunction with Figure 5 -Attached Figure 8 As shown, the centering mechanism includes a guide structure, which includes a double-section telescopic rod 14. One end of the two sets of double-section telescopic rods 14 are fixed to the inner wall of the accommodating groove 3, and the other ends of the two sets of double-section telescopic rods 14 are respectively fixed to the outside of the empty shell 15; It can be seen from the above connection relationship that the guide structure is provided for convenience, and the empty shell 15 can only move linearly in the receiving groove 3.

[0024] Specifically, in conjunction with Figure 7 and attached Figure 8 As shown, the centering mechanism also includes two extension plates 16, two guide columns 17 and a rotating ring 18, one end of the extension plate 16 is fixed to the outside of the empty shell 15, one end of the two guide columns 17 is respectively fixed to the other end of the two extension plates 16, the base 21 is disc-shaped as a whole and is rotatably installed in the ring of the rotating ring 18, the annular surface of the rotating ring 18 is provided with two arc grooves 22, the two arc grooves 22 are centrally symmetrical with the central axis of the rotating ring 18 as the center, the two guide columns 17 are respectively slidably set in the two arc grooves 22, the outer side of the rotating ring 18 is provided with a notch with an inverted T-shaped cross section, and a positioning strip 19 adapted thereto is slidably provided inside the notch, one end of the positioning strip 19 and the notch are jointly fixed with a first spring 20, and a positioning hole adapted to the positioning strip 19 is provided on the inner wall of one side of the accommodating groove 3; From the above connection relationship, it can be seen that: the negative electrode is placed on the soft body on the base 21, and the rotating ring 18 is twisted. The rotating ring 18 rotates relative to the base 21. The arc groove 22 on the rotating ring 18 causes the two empty shells 15 to move synchronously toward the base 21 through the moving column and the extension plate 16, so that the empty shells 15 overlap at the base 21. At this time, the soft body in the two empty shells 15 wraps the negative electrode, thereby completing the wrapping and fixing. The soft body is deformed according to the contour of the negative electrode. When the two empty shells 15 are completely attached, the positioning bar 19 on the rotating ring 18 is aligned with the positioning hole. At this time, the first spring 20 inserts the positioning bar 19 into the positioning hole, so that the rotating ring 18 cannot rotate.

[0025] Specifically, in conjunction with Figure 7 As shown, the fluid is composed of crystal mud, space sand, porous substrate and non-Newtonian liquid. The specific production process of the fluid is as follows: In the first step, the porous substrate is immersed in a non-Newtonian liquid so that the non-Newtonian liquid is immersed in the porous substrate; In the second step, the soaked porous substrate is cut into granules; The third step is to mix the crystal mud, space sand and the porous substrate particles obtained in the second step together, and knead them continuously to make the space sand and the porous substrate particles evenly distributed in the crystal mud; To supplement the above: a sponge can be used as the porous substrate, and a mixture of crystal mud and space sand can obtain a soft and moderate fluid with strong plasticity, so that it can fit well with the negative electrode, while a mixture of starch and water can be used as the non-Newtonian liquid.

[0026] From the above connection relationship, it can be seen that: when a violent impact or drop occurs during transportation (high speed or high stress), the non-Newtonian liquid wrapping the object will instantly thicken or even solidify. This liquid-solid transition process itself consumes a large amount of impact energy, which is used to destroy the microstructure or particle network inside the liquid. After transforming into a quasi-solid state, the material can more effectively disperse the impact force to the entire wrapping layer and the surface of the object, avoiding stress concentration and thus protecting the internal object.

[0027] Specifically, in conjunction with Figure 3 and attached Figure 4As shown, first grooves 7 are provided on both sides of the disk surface of the tray 1, second grooves 8 are provided on both sides of the bottom of the tray 1, two positioning shafts 10 are rotated inside the first groove 7, a rotating plate 11 is fixed to the outside of the positioning shaft 10, the top of the rotating plate 11 is hook-shaped, a flat head plate 9 is fixed upside down inside the second groove 8, and a second spring 12 is fixed to the bottom end of the rotating plate 11, a hole groove is provided on both sides of the tray 1, and a cone 13 is slidably inserted in the hole groove, the cone 13 is located between the two rotating plates 11, a limit ring 23 is fixed at the edge of the hole groove, a third spring 5 is provided on the top of the inner top of the socket 4, one end of the third spring 5 is fixed to the top inner wall of the socket 4, and the other end of the third spring 5 is fixed to the contact plate 6; Supplementary explanation of the above: the top of the rotating plate 11 is hook-shaped, and the hook head rotates in a wedge-shaped manner, the flat head plate 9 is T-shaped as a whole, and the two ends of the flat head plate 9 are wedge-shaped; From the above connection relationship, it can be seen that: when the pallets 1 are stacked, the rotating plate 11 in the first groove 7 of the lower pallet 1 is inserted into the second groove 8 of the upper pallet 1, and the flat head plate 9 in the second groove 8 pushes the rotating plates 11 apart from each other. During this process, the second spring 12 between the two rotating plates 11 is compressed. When the hook head of the rotating plate 11 is stuck in the flat head of the flat head plate 9, the second spring 12 is reset, thereby completing the fixation; in the above process, the column 2 is inserted into the socket 4, pushing the contact plate 6 into the socket 4, and the third spring 5 is compressed; when disassembling, the cone 13 is pushed into the first groove 7, and the cone head of the cone 13 pushes the two rotating plates 11 apart from each other, the third spring 5 is reset, and the contact plate 6 lifts up the upper pallet 1.

[0028] Working principle: During the fixing work, the negative electrode is placed on the soft body on the base 21, and the rotating ring 18 is twisted. The rotating ring 18 rotates relative to the base 21. The arc groove 22 on the rotating ring 18 moves the two empty shells 15 synchronously toward the base 21 through the moving column and the extension plate 16, so that the empty shells 15 overlap at the base 21. At this time, the soft body in the two empty shells 15 wraps the negative electrode, thereby completing the wrapping and fixing. The soft body is deformed according to the contour of the negative electrode, and the positioning bar 19 on the rotating ring 18 is aligned with the positioning hole. At this time, the first spring 20 inserts the positioning bar 19 into the positioning hole, so that the rotating ring 18 cannot rotate; since the fluid in the soft body is composed of crystal mud, space sand, porous substrate and non-Newtonian liquid, the mixture of crystal mud and space sand can obtain a soft and moderate fluid with strong plasticity. This allows for a good fit with the negative electrode. If a violent impact or drop (high speed or high stress) occurs during transportation, the non-Newtonian liquid wrapping the object will instantly thicken or even solidify. This liquid-to-solid transition process itself consumes a large amount of impact energy, which is used to destroy the microstructure or particle network inside the liquid. After transforming into a quasi-solid state, the material can more effectively disperse the impact force to the entire wrapping layer and the surface of the object, avoiding stress concentration and thus protecting the internal object. When the pallets 1 are stacked, the rotating plate 11 in the first groove 7 of the lower pallet 1 is inserted into the second groove 8 of the upper pallet 1, and the flat head plate 9 in the second groove 8 pushes the rotating plates 11 apart from each other. During this process, the second spring 12 between the two rotating plates 11 is compressed. When the hook head of the rotating plate 11 is stuck in the flat head of the flat head plate 9, the second spring 12 is reset, thereby completing the fixation; in the above process, the plug 2 is inserted into the socket 4, pushing the contact plate 6 into the socket 4, and the third spring 5 is compressed; when disassembling, the cone 13 is pushed into the first groove 7, and the cone head of the cone 13 pushes the two rotating plates 11 apart from each other, the third spring 5 is reset, and the contact plate 6 lifts up the upper pallet 1.

[0029] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
