Description

Technical Field

[0001] The utility model relates to the technical field of photoresist transportation, in particular to a photoresist refrigerated transportation packaging box. Background Art

[0002] Photoresist is a key material for fine-pattern processing in microelectronics. The technology behind photoresist is complex, and there are numerous varieties. Based on their chemical reaction mechanisms and development principles, they can be categorized as negative-working and positive-working. Negative-working resists become insoluble upon exposure to light, while positive-working resists are insoluble in certain solvents but become soluble upon exposure. Leveraging this property, photoresist can be applied as a coating to etch desired circuit patterns onto silicon wafer surfaces.

[0003] For example, the authorization announcement number "CN215624068U" is named as an insulated packaging box for transporting photoresist products. A buffer mechanism is provided at the connection between the insulated box and the annular docking plate. When the insulated box is bumpy, the insulated box can be effectively buffered to achieve the purpose of protecting the photoresist products inside. However, the insulated packaging box for transporting photoresist products has relatively high requirements for various conditions when packing and transporting photoresist, especially the factors of lighting and temperature. When the temperature of the storage environment is relatively high, the performance and quality of the photoresist will decline. The current insulated packaging boxes for transporting photoresist products lack a structure to maintain stable temperature. Transporting in high temperature weather can easily destroy the properties of the photoresist, resulting in poor transportation effect of the insulated packaging boxes for transporting photoresist products.

[0004] At the same time, the existing thermal insulation packaging boxes for transporting photoresist products are locked and fixed by multiple structures inside the box, and springs are also provided inside the box for the purpose of buffering and vibration reduction. However, the spring is a relatively unstable structure and will deform during compression and ejection. Therefore, it reserves space for the buffered photoresist product to move, causing the photoresist to shake unstably, thereby reducing the transportation protection function of the thermal insulation packaging boxes for transporting photoresist products. Utility Model Content

[0005] The utility model aims to solve the problems of poor transportation effect and weak transportation protection function of heat-insulating packaging boxes used for transporting photoresist products, and proposes a refrigerated transportation packaging box for photoresist.

[0007] A photoresist refrigerated transport packaging box is designed, which includes a base, a packaging box body and a bottom block. Multiple bottom blocks are fixedly connected to the lower end of the base, and the packaging box body is fixedly connected to the top of the base. A transportation stable protection structure is provided on the inner side of the packaging box body, a packaging box firm covering structure is provided above the outer wall of the packaging box body, and a packaging box easy-to-lift structure is provided on both sides of the outer wall of the packaging box body.

[0013] Preferably, a plurality of splicing holes are fixedly opened on the top end of the top cover, and the inner sides of the plurality of splicing holes are movably connected to the bottom block below the other base.

[0014] The utility model proposes a photoresist refrigerated transport packaging box, which has the following beneficial effects: a sealing plate is made of rubber material, and the sealing plate is placed above the inner liner before the top cover is buckled and fixed. The sealing plate improves the sealing inside the photoresist storage tank, ensuring that the photoresist will not deteriorate in a short time. The support seat can fix the temperature sensor by screws. The refrigeration tank is made of metal copper, which has good thermal conductivity.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Example 1:

[0025] See also Figure 1-6 : In this embodiment, a photoresist refrigerated transport packaging box includes a base 1, a packaging box body 2 and a bottom block 3. Multiple bottom blocks 3 are fixedly connected to the lower end of the base 1, and the packaging box body 2 is fixedly connected to the top of the base 1. The packaging box body 2 is made of stainless steel metal material, which is corrosion-resistant, pressure-resistant and stronger. The packaging box body 2 is welded on the top of the base 1, and a photoresist tank 5 filled with photoresist liquid is placed inside the packaging box body 2. In this way, the packaging box bodies 2 can be stacked and placed on a vehicle for transportation and handling. A transportation stable protection structure 4 is provided on the inner side of the packaging box body 2, a packaging box firm covering structure 6 is provided above the outer wall of the packaging box body 2, and a packaging box easy-to-lift structure 8 is provided on both sides of the outer wall of the packaging box body 2.

[0026] The transport stability protection structure 4 includes an inner liner 41 and a positioning plate 42. The inner liner 41 is fixedly installed on the inner wall of the packaging box body 2. The inner liner 41 is made of nickel steel alloy and has strong sealing and hardness. The inner liner 41 is installed in the inner wall of the packaging box body 2, which can mainly enhance the ability of the packaging box body 2 to resist collision and external impact. The inner side of the inner liner 41 is fixedly connected with a positioning plate 42. The positioning plate 42 is embedded in the inner liner 41 and welded and fixed. Four circular holes of the same size and diameter are drilled inside the positioning plate 42. The circular holes are used to place photoresist tanks 5 filled with photoresist.

[0027] A plurality of vertical blocks 43 are fixedly connected to the lower end of the inner wall of the liner 41, and a plurality of support frames 45 are fixedly installed on the side walls of the plurality of vertical blocks 43. The support frames 45 are welded to the outside of the vertical blocks 43. Inflatable bubbles 46 that are lifted and inflated are manually placed in the support frames 45. The interiors of the plurality of support frames 45 are fixedly connected with inflatable bubbles 46.

[0028] The inflatable bubbles 46 are made of plastic film. When inflated, the volume of the inflatable bubbles 46 will expand and clamp the photoresist tank 5 set inside. At the same time, the flexible inflatable bubbles 46 can play a role in buffering and reducing vibration. The bottom end of the inner wall of the inner liner 41 is fixedly connected to an anti-knock layer 44. The anti-knock layer 44 is made of rubber material. When the photoresist tank 5 is placed in the inner liner 41, the anti-knock layer 44 will preferentially contact the bottom surface of the photoresist tank 5, thereby improving the protection effect of the photoresist tank 5.

[0029] The inner liner 41 is made of nickel steel alloy and has strong sealing and hardness. The inner liner 41 is installed in the inner wall of the packaging box body 2, which can mainly enhance the ability of the packaging box body 2 to resist collision and external impact. The positioning plate 42 is embedded in the inner liner 41 and welded and fixed. Four circular holes of the same size and diameter are drilled inside the positioning plate 42. The circular holes are used to place the photoresist tank 5 filled with photoresist. The support frame 45 is welded to the outside of the vertical block 43. The inflatable bubble 46 that is lifted and inflated can be manually placed in the support frame 45. The inflatable bubble 46 is made of plastic. The air bubble 46 is made of a film, and the volume of the air-filled bubble 46 will become larger and expand to clamp the photoresist tank 5 set on the inside. At the same time, the flexible air-filled bubble 46 can play a role in buffering and vibration reduction. The anti-knock layer 44 is made of rubber material. When the photoresist tank 5 is placed in the inner liner 41, the anti-knock layer 44 will preferentially contact the bottom surface of the photoresist tank 5. The air bag is used for flexible buffering, and the contact area is large, which makes it difficult to reserve space for movement. In addition, the multi-layer protection structure on the outside further improves the protection ability of the photoresist during transportation, thereby improving the protection effect of the photoresist refrigerated transport packaging box.

[0030] The inner side of the positioning plate 42 is movably connected to a plurality of photoresist tanks 5 , the lower ends of the plurality of photoresist tanks 5 are movably connected to the top of the anti-smash layer 44 , and the side walls of the plurality of photoresist tanks 5 are tightly pressed against the outer sides of the inflatable bubbles 46 .

[0031] The packaging box's firm covering structure 6 includes a top cover 61 and a connecting plate 65. The top cover 61 is movably connected to the top of the packaging box body 2. The top cover 61 is slightly larger than the packaging box body 2 below. Multiple bending hooks 62 are fixedly connected on both sides of the outer wall of the top cover 61. The bending hooks 62 are welded on both sides of the top cover 61. Multiple connecting plates 65 are fixedly connected to the top of the outer wall of the packaging box body 2. When the top cover 61 is fixed normally, the top cover 61 is first covered on the top of the packaging box body 2.

[0032] In this way, the positions of the bending hooks 62 on both sides will be opposite to the positions of the connecting plates 65 on the side walls of the packaging box body 2, and the outer sides of multiple bending hooks 62 are movably connected with tightening rings 63, and the lower parts of the outer walls of multiple tightening rings 63 are fixedly connected with fitting blocks 64. Then, the inner through holes of the tightening rings 63 processed by the external device are inserted into the bending hooks 62, and the fitting blocks 64 under the tightening rings 63 can fit with the connecting plates 65. Finally, the connection plates 65 and the fitting blocks 64 are fixedly tightened by tightening the bolts 66. In this way, the tightening rings 63 will cover the outer sides of the bending hooks 62, and the top cover 61 cannot be opened upwards. The inner sides of multiple fitting blocks 64 are threadedly connected with bolts 66, and the ends of multiple bolts 66 are connected to the inner threads of the connecting plates 65.

[0033] A refrigerated transport structure 7 is provided above the inner liner 41. The refrigerated transport structure 7 includes a temperature display screen 71 and a sealing plate 72. The sealing plate 72 is movably connected to the top of the inner liner 41. The sealing plate 72 is made of rubber material. The sealing plate 72 is placed above the inner liner 41 before the top cover 41 is fastened and fixed. The sealing plate 72 improves the sealing performance of the interior of the photoresist storage tank 5 to ensure that the photoresist will not deteriorate in a short time. The top end of the sealing plate 72 is movably connected to the inner side of the top cover 61, and the temperature display screen 71 is fixedly connected to the front of the outer wall of the top cover 61.

[0034] The temperature display screen 71 is electrically connected to the temperature sensor 74. The temperature sensor 74 is a relatively mature technical means. It detects and identifies the external temperature through a non-contact thermal resistor. The identified temperature will be displayed above the temperature display screen 71, which is convenient for the staff to refer to the storage temperature of the photoresist. A support base 73 is fixedly connected to the bottom of the sealing plate 72. The support base 73 can fix the temperature sensor 74 by screws. The temperature sensor 74 is fixedly installed below the support base 73. A plurality of cold storage slots 75 are fixedly connected to the top of the positioning plate 42. The cold storage slots 75 are made of metal copper. Metal copper has good thermal conductivity. The metal copper is made into a groove shape. A frozen ice bag is placed inside. During the transportation of the photoresist, the ice bag will continue to melt and absorb heat, thereby maintaining the stability of the temperature inside the storage box.

[0035] The sealing plate 72 is made of rubber material and is placed above the inner liner 41 before the top cover 41 is fastened and fixed. The sealing plate 72 improves the sealing inside the photoresist storage tank 5 to ensure that the photoresist will not deteriorate in a short time. The support seat 73 can fix the temperature sensor 74 by screws. The refrigeration tank 75 is made of metal copper. Metal copper has good thermal conductivity. The metal copper is made into a groove shape, and a frozen ice bag is placed inside. During the transportation of the photoresist, the ice bag will continue to melt and absorb heat, thereby maintaining the stability of the temperature inside the storage box and improving the transportation effect of the photoresist refrigerated transportation box.

[0036] Working principle:

[0037] Photoresist, also known as photoresist, refers to an etching-resistant film material whose solubility changes due to irradiation or radiation of ultraviolet light, electron beam, ion beam, X-ray, etc. It is a light-sensitive mixed liquid composed of three main components: photosensitive resin, sensitizer and solvent. Photoresist refrigerated transport packaging boxes are used to stack the photoresist processed and filled at the production site on a transport vehicle and transported to the location where the photoresist is worked. Photoresist must be transported in sealed packaging to prevent impurities and moisture in the air from affecting its quality; photoresist should avoid severe vibration during transportation to avoid affecting its performance and quality; photoresist containers should not be subjected to excessive pressure to avoid damage to the container and cause photoresist leakage; photoresist should be transported at an appropriate temperature to avoid excessively high or low temperatures that may cause its performance and quality to deteriorate;

[0038] The main external structure of the photoresist refrigerated transport box:

[0039] The packaging box body is made of stainless steel metal material, which is corrosion-resistant, pressure-resistant and more solid. The packaging box body is welded on the top of the base 1, and a photoresist tank 5 filled with photoresist liquid is placed inside the packaging box body 2. In this way, the packaging box body 2 can be stacked and placed on a vehicle for transportation and handling;

[0040] Cushioning protection structure of photoresist refrigerated transport packaging box:

[0041] The inner liner 41 is made of nickel steel alloy and has strong sealing and hardness. The inner liner 41 is installed in the inner wall of the packaging box body 2, which can mainly enhance the ability of the packaging box body 2 to resist collision and external impact. The positioning plate 42 is embedded in the inner liner 41 and welded and fixed. Four circular holes of the same size and diameter are drilled inside the positioning plate 42. The circular holes are used to place the photoresist tank 5 filled with photoresist. The support frame 45 is welded to the outside of the vertical block 43. The support frame 45 is manually placed with an inflatable bubble 46 that is lifted and inflated. The inflatable bubble 46 is made of plastic film. The inflatable bubble 46 will expand and clamp the photoresist tank 5 set inside. At the same time, the flexible inflatable bubble 46 can play a role in buffering and vibration reduction. The anti-knock layer 44 is made of rubber material. When the photoresist tank 5 is placed in the inner liner 41, the anti-knock layer 44 will preferentially contact the bottom surface of the photoresist tank 5, thereby improving the protection effect of the photoresist tank 5.

[0042] Top cover fixing structure of photoresist refrigerated transport packaging box:

[0043] The top cover 61 is slightly larger than the packaging box body 2 below. When the top cover 61 is fixed normally, the top cover 61 is first covered on the top of the packaging box body 2, so that the positions of the bent hooks 62 on both sides are opposite to the positions of the connecting plates 65 on the side walls of the packaging box body 2. Then, the inner through holes of the externally processed clamping ring 63 are inserted into the bent hooks 62, and the fitting blocks 64 under the clamping ring 63 can fit with the connecting plates 65. Finally, the connection plates 65 and the fitting blocks 64 are strengthened by tightening the bolts 66. In this way, the clamping ring 63 will cover the outer sides of the bent hooks 62, and the top cover 61 cannot be opened upwards.

[0044] Refrigerated transport structure of photoresist refrigerated transport packaging box:

[0045] The sealing plate 72 is made of rubber material and is placed above the inner liner 41 before the top cover 41 is fastened and fixed. The sealing plate 72 improves the sealing inside the photoresist storage tank 5 to ensure that the photoresist will not deteriorate in a short time. The support seat 73 can fix the temperature sensor 74 by screws. The cold storage tank 75 is made of metal copper, which has good thermal conductivity. The metal copper is made into a groove shape, and a frozen ice bag is placed inside. During the transportation of the photoresist, the ice bag will continue to melt and absorb heat, thereby maintaining the stability of the temperature inside the storage packaging box.

[0046] Example 2:

[0047] See also Figure 1-6 : In this embodiment, a photoresist refrigerated transport packaging box includes a packaging box that is easy to lift structure 8, including side panels 81 and handles 83. Multiple side panels 81 are fixedly connected to both sides of the outer wall of the packaging box body 2. The inner sides of the two side panels 81 are rotatably connected to the horizontal axis 82. The handles 83 can be flipped a certain distance along the side panels 81 under the support of the horizontal axis 82. The handles 83 make it convenient for staff to lift the packaging box body 2 and transport it to the vehicle. The outer sides of the two horizontal axes 82 are fixedly sleeved with handles 83.

[0048] A plurality of splicing holes 9 are fixedly opened on the top of the top cover 61. The splicing holes 9 are opened on the top cover 61 above each packaging box body 2, and the bottom block 3 on the base 1 below the upper packaging box body 2 can be inserted into the splicing hole 9 in the top cover 61 above the lower packaging box body 2. In this way, two or more packaging box bodies 2 can be stacked in sequence to save more transportation space. The inner sides of the multiple splicing holes 9 are movably connected to the bottom block 3 below another base 1.

[0049] Working principle:

[0050] The handle 83 can be turned along the side plate 81 to a certain extent under the support of the crossbar 82, so that the staff can easily lift the packaging box body 2 to transport it to the vehicle;

[0051] The splicing holes 9 are opened on the top cover 61 above each packaging box body 2, and the bottom block 3 on the bottom base 1 of the upper packaging box body 2 can be inserted into the splicing hole 9 in the top cover 61 above the lower packaging box body 2, so that two or more packaging box bodies 2 can be stacked in sequence to save more transportation space.
