[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-Figure 11 The present invention provides a technical solution: a disinfection device for irradiation sterilization, comprising a frame 1, and also comprising:

[0044] The upper guide rail 2 is mounted on the top corner of the frame 1 through a bracket, and an annular groove 21 is provided inside;

[0045] The lower guide rail 3 is installed at the top corner of the frame 1 through a bracket, and a strip groove 31 is provided inside; the lower guide rail 3 is arranged diagonally with the upper guide rail 2, and there is a partial overlap between the lower guide rail 3 and the upper guide rail 2;

[0046] The upper bracket 22 and the lower bracket 32 ​​are respectively slidably disposed in the upper guide rail 2 and the lower guide rail 3 for placing items, and the ends of the upper bracket 2 and the lower bracket 3 are fixed with a rotating shaft 73;

[0047] The flipping structures are in pairs and are respectively located in the grooves below the strip groove 31 and the annular groove 21, and are used for flipping the upper bracket 22 and the lower bracket 32, and can be used for resetting the lower bracket 32. Through the flipping structure, one corner of the box can be turned upward, so that multiple surfaces of the box are exposed to the irradiation area at the same time, so as to achieve simultaneous irradiation sterilization of multiple surfaces of the surface of the object;

[0048] The transfer structure 5 is installed in the groove below the annular groove 21 and is located in the overlapping area of ​​the lower guide rail 3 and the upper guide rail 2, and is used to transfer the items on the upper guide rail 2 to the lower guide rail 3, so that the unirradiated surface of the items is exposed to the second irradiation area. Two irradiations can achieve full-face irradiation sterilization of the box;

[0049] The buffer portion 11 is disposed in the strip groove 31 and is located in the overlapping area of ​​the lower guide rail 3 and the upper guide rail 2;

[0050] The reciprocating structures 6 are in pairs and are used to drive the upper bracket 22 and the lower bracket 32 ​​to reciprocate;

[0051] The one-way gate 12 is rotatably arranged at the end of the annular groove 21 through a torsion spring, and is used to guide the return of the upper bracket 22 from the lower groove in the annular groove 21 to the upper groove;

[0052] The one-way docking rack 8 is obliquely arranged in the strip groove 31, and is used for the one-way flipping of the lower bracket 32, so that the lower bracket 32 ​​can cover the articles with the upper bracket 22;

[0053] The resetting structures are installed in the groove above the annular groove 21, in pairs, and are used to reset the upper bracket 22 to the disinfection angle and the feeding angle respectively;

[0054] Specifically, the box of items to be sterilized is conveyed to the upper bracket 22 by a conveyor belt;

[0055] See also Figure 7 , the starting position of the upper bracket 22 is located at Figure 7 In the upper right center, the lower bracket 32 ​​starts at Figure 7 In the lower left middle portion, during the movement of the upper bracket 22, the reciprocating structure 6 drives the upper bracket 22 to move along the groove below the annular groove 21, and the upper bracket 22 moves toward the lower bracket 32. When the upper bracket 22 passes through the first flipping structure, the upper bracket 22 flips 45° counterclockwise around the rotating shaft 73 fixed thereto ( Figure 7 ), with one corner of the box facing upward (see Figure 7 In the stereoscopic view), the upper bracket 22 continues to move and

[0056] After the box passes through the irradiation area, the three sides of the box are irradiated and sterilized at the same time. After the box passes through the irradiation area, the upper bracket 22 is in the second flip structure, and the upper bracket 22 rotates 45° counterclockwise around the rotating shaft 73 fixed thereto, so that the side of the bottom (bottom plate 71) of the upper bracket 22 carrying the items faces the lower bracket 32, and the upper bracket 22 continues to move;

[0057] At the same time, the lower bracket 32 ​​moves along the strip groove 31 toward the upper bracket 22. When the lower bracket 32 ​​passes through the first flipping structure, the lower bracket 32 ​​flips 45° clockwise around the rotating shaft 73 fixed thereto, so that the surface of the lower bracket 32 ​​used to carry articles faces upward at the same time. The lower bracket 32 ​​continues to move and passes through the irradiation area, and the surface of the lower bracket 32 ​​used to carry articles is irradiated and sterilized to avoid bacteria on the lower bracket 32 ​​and contamination of the articles. After the lower bracket 32 ​​passes through the irradiation area, the lower bracket 32 ​​rotates 45° clockwise around the rotating shaft 73 fixed thereto again under the action of the second flipping structure. The lower bracket 32 ​​passes through the one-way docking rack 8, and the lower bracket 32 ​​rotates 90° clockwise, so that the side of the bottom (bottom plate 71) of the lower bracket 32 ​​carrying articles faces the upper bracket 22.

[0058] The upper bracket 22 and the lower bracket 32 ​​are close to each other and contact each other, covering the articles therein. The transfer structure 5 drives the upper bracket 22 and the lower bracket 32 ​​to rotate 90° counterclockwise, so that the center of gravity of the articles is pressed on the lower bracket 32, completing the transfer of the articles. The lower bracket 32 ​​moves in the opposite direction, passes over the one-way docking rack 8, and passes through two flipping structures in sequence. When passing through the first flipping structure, the three sides of the articles that have not been irradiated and sterilized face the irradiation area, and are subjected to the second irradiation and sterilization. When passing through the second flipping structure, the lower bracket 32 ​​faces two sides of the articles exposed to the outside of the equipment to facilitate the removal of the articles. Under the action of the one-way gate 12, the upper bracket 22 enters the upper part of the annular groove 21, so that a height difference is generated between the upper bracket 22 and the articles, avoiding reverse dragging of the articles and causing the articles to fall. The upper bracket 22 passes through two reset structures in sequence, and the upper bracket (22) is reset to the disinfection angle and the feeding angle in sequence. The upper bracket 22 returns to the initial position after irradiation and sterilization.

[0059] To summarize, when the upper bracket 22 moves toward the lower bracket 32 ​​or the lower bracket 32 ​​moves toward the upper bracket 22, one of the corners of the box can be turned upward through the flipping structure, so that multiple surfaces of the box are exposed to the irradiation area at the same time, and irradiation sterilization of multiple surfaces of the object can be achieved at the same time. During the return journey, the surface of the lower bracket 32 ​​or the upper bracket 22 carrying the object can be exposed to the irradiation area at the same time, avoiding the bacteria remaining on the surface of the lower bracket 32 ​​or the upper bracket 22 from adhering to the surface of the object and reducing the effect of irradiation sterilization; the lower bracket 32 ​​and the upper bracket 22 can cover the object in all directions, and can transfer the object from the upper bracket 22 to the lower bracket 32 ​​by rotation, so that the unirradiated surface of the object is exposed to the second irradiation area, and two irradiations can achieve full-face irradiation sterilization of the box, shortening the irradiation time of the object, improving work efficiency, and reducing the risk of bacteria adhering again after irradiation.

[0060] As a further solution of the present invention, the transmission structure 5 includes:

[0061] The transmission rack 51 is slidably disposed in the groove below the annular groove 21;

[0062] The slide bar 52 is fixedly mounted at the bottom of the upper guide rail 2, and an exchange spring 53 is fixedly mounted between the slide bar 52 and the transmission rack 51;

[0063] The trigger bar 54 is fixed to the end of the transmission rack 51 and is arranged obliquely so as to be deformed by being squeezed by the rotating shaft 73;

[0064] Specifically, the initial position of the transfer rack 51 is located below the one-way gate 12. When the rotating shaft 73 fixed to the upper bracket 22 moves toward the lower bracket 32, the trigger bar 54 first contacts the rotating shaft 73. The rotating shaft 73 causes the trigger bar 54 to gradually deform and drive the transfer rack 51 to move and stretch the exchange spring 53 through the trigger bar 54. When the upper bracket 22 collides with the lower bracket 32, the top of the trigger bar 54 is lower than the rotating shaft 73, the exchange spring 53 releases the elastic force, and the transfer rack 51 drives the rotating shaft 73 to rotate 90° to complete the transfer of the item, and the transfer rack 51 will not hinder the return of the upper bracket 22.

[0065] As a further solution of the present invention, the reciprocating structure 6 includes: a driving motor 61, mounted on the frame 1;

[0066] The reciprocating screw rod 62 is rotatably disposed on the frame 1 and is coaxially fixed with the output shaft of the driving motor 61; the reciprocating block 63 is slidably disposed in the reciprocating screw rod 62;

[0067] A driving block 64 is mounted on the rotating shaft 73 and is used to drive the rotating shaft 73 to move back and forth;

[0068] Specifically, the driving motor 61 drives the reciprocating screw 62 to rotate through the output shaft, the reciprocating screw 62 drives the driving block 64 to reciprocate through the reciprocating block 63, and the driving block 64 drives the rotating shaft 73 to reciprocate, thereby realizing the reciprocating movement of the upper bracket 22 and the lower bracket 32;

[0069] The two drive motors 61 are asynchronous, and can adapt to the movement of the upper bracket 22 and the lower bracket 32 ​​by starting and stopping the drive motors 61 or controlling the rotation speed.

[0070] As a further solution of the present invention, the upper bracket 22 and the lower bracket 32 ​​both include a bottom plate 71 and a side plate 72, the side plate 72 is an L-shaped structure, the side plate 72 is vertically arranged with the bottom plate 71, and a rotating shaft 73 is fixed on one side of the side plate 72;

[0071] Specifically, the L-shaped side plate 72 can make one side of the article box face the direction of movement, and the rotating shaft 73 can make three sides of the article face upward at the same time, thereby achieving single-time multi-side radiation sterilization.

[0072] As a further solution of the present invention, each pair of the flip structures includes two pairs of flip racks 41 and one flip gear 42, and the two pairs of flip racks 41 are respectively arranged on both sides of the radiation area, the flip gear 42 is coaxially fixed with the rotating shaft 73, and the flip gear 42 is fixed with a limiter 43, and the limiter 43 applies flipping resistance to the flip gear 42;

[0073] Specifically, the flip gear 42 can move with the rotating shaft 73. When the flip gear 42 contacts the flip rack 41, the rotating shaft 73 is driven to rotate. The flip rack 41 is arranged on both sides of the irradiation area and can adjust the direction before or after the irradiation of the object. The limiter 43 can increase the flipping resistance of the flip gear 42 to prevent the flip gear 42 from rotating when it does not contact the flip rack 41, which makes it impossible to fully irradiate and sterilize the object.

[0074] As a further solution of the present invention, the reset structure includes a reset rack 13 installed in the annular groove 21 and capable of meshing with the flip gear 42;

[0075] Specifically, when the flip gear 42 contacts the reset rack 13, the flip gear 42 can drive the rotating shaft 73 to rotate, thereby realizing the flipping of the upper bracket 22. When the upper bracket 22 encounters the first reset rack 13 during the return journey, the upper bracket 22 rotates 135° clockwise (by Figure 7 When the upper bracket 22 encounters the second reset rack 13 on its return journey, the upper bracket 22 rotates 45° clockwise to reset the upper bracket 22 to its initial angle, facilitating the placement of items.

[0076] As a further solution of the present invention, spring plates 14 are arranged above the buffer portion 11 , the flip rack 41 and the reset rack 13 , and the spring plates 14 are elastically arranged on the upper guide rail 2 and the lower guide rail 3 respectively; the spring plates 14 can make way for the limiter 43 .

[0077] As a further solution of the present invention, the two ends of the one-way docking rack 8 are fixed with a yielding shaft 81, and the upper and lower sides of the inner wall of the strip groove 31 are provided with a yielding groove 82 of L-shaped structure, and the yielding groove 82 can be alternately slidably arranged with the yielding shaft 81, wherein the yielding groove 82 at the bottom is provided with an incomplete tooth ring 83 through the rotation of a torsion spring, and the yielding shaft 81 is provided with a positioning groove 84;

[0078] For details, see Figure 6 and Fig.10 When the lower bracket 32 ​​approaches the upper bracket 22, the flip gear 42 contacts and drives the one-way docking rack 8 to move to the left. Figure 6 , the lower yielding shaft 81 moves into the incomplete gear ring 83, and the incomplete gear ring 83 positions the bottom yielding shaft 81 through the positioning groove 84. Subsequently, the upper yielding shaft 81 rotates and disengages from the top yielding groove 82. When the one-way docking rack 8 rotates to a horizontal position, the ruler teeth of the one-way docking rack 8 engage with the ruler teeth of the flip gear 42, and the lower bracket 32 ​​is driven to rotate 90° through the flip gear 42, so that the lower bracket 32 ​​can cover the article with the upper bracket 22; after the flip gear 42 disengages from the one-way docking rack 8, the torsion spring presses the top yielding shaft 81 into the positioned yielding groove 82 through the incomplete gear ring 83;

[0079] When the lower bracket 32 ​​returns, the difference from the above process is that the one-way docking rack 8 moves in the opposite direction, and the flip gear 42 contacts the back of the one-way docking rack 8 without rotating, thereby preventing items from falling.
