Description

Technical Field

[0001] The utility model belongs to the technical field of LEDs, and in particular relates to a liquid cooling and heat dissipation device for an LED light source of an artificial intelligence sorting machine. Background Art

[0002] The AI sorting machine is an advanced device that uses artificial intelligence (AI) and machine vision principles, combined with deep learning algorithms and image processing technology, to automatically sort and classify items. It uses a camera to capture image information of items, then processes it through a complex algorithm to identify their characteristics, such as shape, color, and texture, and automatically sorts them to designated locations.

[0003] The LED light source used in the AI sorting machine is an advanced lighting technology designed specifically for high-precision identification and classification tasks. It combines the outstanding characteristics of LEDs, such as high brightness, low energy consumption, and precisely controllable luminous properties, to provide ideal lighting conditions for the sorting process.

[0004] After long-term use, the temperature of LED light sources will become high. When the temperature rises, it cannot be dissipated in time, resulting in light decay and reduced service life. In order to extend the service life of LED light sources, liquid cooling is adopted for LED light sources.

[0005] Patent CN110566847A discloses a centralized liquid-cooled LED stage lighting matrix system. Although this system achieves the purpose of cooling the LED light source, since the serpentine tube is directly connected to the cold water supply pipe and the hot water return pipe, when the LED light source is damaged and needs to be removed and replaced, the cold water supply pipe and the hot water return pipe need to be removed from the serpentine tube. Since the cold water supply pipe and the hot water return pipe are not sealed and there is cooling water in the cold water supply pipe and the hot water return pipe, the cooling water will flow out after the cold water supply pipe and the hot water return pipe are removed, resulting in a waste of cooling water. In addition, the flowing cooling water needs to be cleaned, causing unnecessary trouble and reducing the efficiency of removing and replacing the LED light source. Utility Model Content

[0006] In order to solve the technical problem of low efficiency in removing and replacing LED light sources, the utility model provides a liquid cooling and heat dissipation device for LED light sources of an artificial intelligence sorting machine.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] An artificial intelligence sorting machine LED light source liquid cooling heat dissipation device, including multiple shells,

[0009] The cooling layer is arranged at the rear end of the shell.

[0010] PCB board, connected to the side of the cooling layer close to the front end of the shell,

[0011] The main body of the LED light source is connected to the side of the PCB board close to the front end of the housing.

[0012] The serpentine tube is set in the cooling layer.

[0013] The two ends of the serpentine tube pass through the cooling layer respectively, and the two ends of the serpentine tube are respectively inserted into the blocking tube. The upper end of one blocking tube is connected to the supply pipe, and the upper end of the other blocking tube is connected to the return pipe.

[0014] A trapezoidal groove ring is connected to the upper part of the sealing tube, a pressure ring is arranged in the middle of the sealing tube, a first spring is connected between the trapezoidal groove ring and the pressure ring, a connecting rod is connected to the side of the pressure ring close to the trapezoidal groove ring, a sealing block is connected to the end of the connecting rod away from the pressure ring, and a sealing ring is connected to the side of the sealing block close to the connecting rod.

[0015] Preferably, the sealing block is in a trapezoidal shape, corresponding to the middle portion of the trapezoidal groove ring.

[0016] Preferably, positioning rings are connected to the outside of both ends of the serpentine tube, symmetrically arranged through holes are opened in the middle of the positioning rings, and symmetrically arranged plugs are connected to the positions corresponding to the through holes on the outside of the blocking tube, and the plugs are inserted into the through holes.

[0017] Preferably, the end of the insert close to the positioning ring is triangular, and one side of the triangle is in contact with the side of the fixing ring away from the blocking tube.

[0018] Preferably, the upper end of the supply pipe is connected to a liquid outlet pipe, one end of the liquid outlet pipe is connected to a water pump, the water pump is connected to the radiator through a pumping pipe, a connecting pipe is connected above the radiator, and the return pipe is connected to the connecting pipe.

[0019] Preferably, symmetrically arranged filter plates are provided on the outer side of the shell at positions corresponding to the cooling layers.

[0020] Preferably, a magnetic sticker is connected to one side of the filter plate close to the shell, and symmetrically arranged slots are provided at positions of the shell corresponding to the magnetic stickers, and the magnetic stickers are adsorbed in the slots.

[0021] Preferably, a splint is provided at a position corresponding to the filter plate of the outer shell, one end of the splint is in contact with the filter plate, a rotating rod is connected to the middle of the splint, and symmetrically arranged positioning seats are connected to the position corresponding to the rotating rod on the outer side of the outer shell. The rotating rod is rotatably connected between the positioning seats, and a second spring is connected between the lower part of the splint away from the end of the filter plate and the outer shell.

[0022] Beneficial effects of the utility model:

[0023] When the LED light source is damaged and is removed and replaced, the supply pipe and the return pipe need to be removed from the two ends of the serpentine pipe respectively. During removal, the two plugs are pinched at the same time so that the front ends of the two plugs are close to the outer wall of the blocking pipe. When the front ends of the plugs correspond to the through holes, the blocking pipe loses its obstruction. At this time, the blocking pipe is taken out from the end of the serpentine pipe. When taken out, the end of the serpentine pipe slides out in the blocking pipe. In this process, under the action of the first spring restoring force, until the sealing block and the sealing ring are in contact with the middle of the trapezoidal groove ring, the pressure ring will always be in contact with the end of the serpentine pipe, and after the sealing block and the sealing ring are in contact with the middle of the trapezoidal groove ring, one end of the serpentine pipe end is still in the blocking pipe, so that before the sealing block and the sealing ring seal the blocking pipe, the end of the serpentine pipe will first seal the blocking pipe to prevent coolant from flowing out of the blocking pipe, without causing waste of cooling water, thereby avoiding unnecessary trouble and improving the efficiency of removing and replacing the LED light source.

[0024] After the filter plate has been used for a long time, the filter holes of the filter plate will be blocked by dust and impurities. In order not to affect the normal heat dissipation of the LED light source, the filter plate needs to be removed for cleaning. When removing the filter plate, press the end of the splint away from the filter plate. After pressing, the splint rotates with the cooperation of the rotating rod and the positioning seat, so that the end of the splint close to the filter plate is tilted and no longer presses the filter plate, so that the magnetic sticker can be taken out of the card slot, and the filter plate can be removed to clean the filter plate. Removing the filter plate for cleaning can clean the filter plate more thoroughly, and dust, impurities and water will not enter the outer shell during cleaning, which will not affect the subsequent use of the LED light source.

[0041] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0042] See also Figure 1 - Figure 8As shown, an artificial intelligence sorting machine LED light source liquid cooling heat dissipation device includes multiple shells 1, and a cooling layer 2 is provided at the rear end of the shell 1 for cooling the LED light source body 202 to improve the service life of the LED light source body 202.

[0043] A side of the cooling layer 2 close to the front end of the housing 1 is connected to a PCB board 201 , and a side of the PCB board 201 close to the front end of the housing 1 is connected to an LED light source body 202 .

[0044] A serpentine tube 21 is provided in the cooling layer 2 for cooling the LED light source body 202 through a cooling liquid.

[0045] Both ends of the serpentine tube 21 pass through the cooling layer 2 respectively, and the two ends of the serpentine tube 21 are respectively inserted into the sealing tube 22. The sealing tube 22 is used to seal the supply pipe 23 and the return pipe 24 to prevent the coolant from flowing out of the supply pipe 23 and the return pipe 24 when the outer shell 1 is removed.

[0046] The upper end of one of the blocking tubes 22 is connected to a supply pipe 23 for adding coolant into the serpentine tube 21 .

[0047] The upper end of the other blocking pipe 22 is connected to a return pipe 24 for bringing the coolant into the water extraction pipe 27 .

[0048] A trapezoidal groove ring 3 is connected to the upper part of the blocking tube 22 to assist in blocking the supply tube 23 or the return tube 24 .

[0049] A pressure ring 32 is provided in the middle of the sealing tube 22 , and a first spring 31 is connected between the trapezoidal groove ring 3 and the pressure ring 32 for resetting the sealing block 34 .

[0050] A connecting rod 33 is connected to the side of the pressure ring 32 close to the trapezoidal groove ring 3, and a sealing block 34 is connected to the end of the connecting rod 33 away from the pressure ring 32. The sealing block 34 cooperates with the trapezoidal groove ring 3 to seal the sealing tube 22, thereby sealing the supply tube 23 or the return tube 24.

[0051] The sealing block 34 is in a trapezoidal shape and corresponds to the middle of the trapezoidal groove ring 3 . Through this arrangement, after the sealing block 34 and the trapezoidal groove ring 3 are fitted together, the sealing performance can be ensured.

[0052] A sealing ring 35 is connected to one side of the sealing block 34 close to the connecting rod 33 to enhance the sealing between the sealing block 34 and the trapezoidal groove ring 3 .

[0053] Positioning rings 4 are connected to the outside of both ends of the serpentine tube 21, and symmetrically arranged through holes are opened in the middle of the positioning ring 4. Symmetrically arranged plug blocks 42 are connected to the positions corresponding to the through holes on the outside of the blocking tube 22. The plug blocks 42 are inserted into the through holes. The plug blocks 42 cooperate with the positioning rings 4 to connect the serpentine tube 21 and the blocking tube 22 to fix the position of the blocking tube 22.

[0054] The end of the insert 42 close to the positioning ring 4 is triangular, and one side of the triangle is in contact with the side of the fixing ring away from the blocking tube 22. Through this arrangement, the blocking tube 22 can be fixed on the outside of the supply pipe 23 or the return pipe 24.

[0055] The insert 42 is made of plastic material and can be reset.

[0056] When the worm tube 21 is in use, the two ends of the worm tube 21 are connected to the supply tube 23 and the return tube 24 respectively. The two ends of the worm tube 21 are respectively corresponding to the sealing tube 22 at the lower end of the supply tube 23 and the return tube 24, and the two ends of the worm tube 21 are inserted into the sealing tube 22. During the insertion process, the end of the worm tube 21 contacts the pressure ring 32 and squeezes the pressure ring 32. After being squeezed, the pressure ring 32 moves toward the position of the trapezoidal groove ring 3. The movement of the pressure ring 32 squeezes the first spring 31. The first spring 31 contracts under the pressure and stores the restoring force. When the pressure ring 32 moves, the sealing block 34 and the sealing ring 35 are driven to move away from the trapezoidal groove ring 3 under the cooperation of the connecting rod 33, so that the sealing tube 22 loses its seal, thereby allowing the coolant to enter the worm tube 21.

[0057] During the process of inserting the end of the serpentine tube 21 into the blocking tube 22, the positioning ring 4 will contact the insert block 42. Since the end of the insert block 42 is triangular, the insert block 42 will be inserted into the middle of the positioning ring 4 through the through hole. With the help of the triangular shape of the end of the insert block 42, it will fit with the positioning ring 4, thereby connecting the serpentine tube 21 and the blocking tube 22, preventing the serpentine tube 21 from falling out of the blocking tube 22.

[0058] When the LED light source is damaged and needs to be removed and replaced, the supply pipe 23 and the return pipe 24 need to be removed from both ends of the serpentine pipe 21 respectively. When removing, the two plug blocks 42 are pinched at the same time so that the front ends of the two plug blocks 42 are close to the outer wall of the blocking pipe 22. When the front ends of the plug blocks 42 correspond to the through holes, the blocking pipe 22 loses its obstruction. At this time, the blocking pipe 22 is taken out from the end of the serpentine pipe 21. When taken out, the end of the serpentine pipe 21 slides out in the blocking pipe 22. In this process, under the action of the restoring force of the first spring 31, until the sealing block 34 is in contact with the sealing block 34, the sealing block 34 is in contact with the sealing block 34. The pressure ring 32 will continue to fit with the end of the serpentine tube 21 until the sealing ring 35 is in contact with the middle of the trapezoidal groove ring 3, and after the sealing block 34 and the sealing ring 35 are in contact with the middle of the trapezoidal groove ring 3, one end of the serpentine tube 21 is still in the blocking tube 22, so that before the sealing block 34 and the sealing ring 35 seal the blocking tube 22, the end of the serpentine tube 21 will first seal the blocking tube 22 to prevent the coolant from flowing out of the blocking tube 22, thereby avoiding waste of cooling water and unnecessary trouble, thereby improving the efficiency of dismantling and replacing the LED light source.

[0059] The upper end of the supply pipe 23 is connected to a liquid outlet pipe 25 , and one end of the liquid outlet pipe 25 is connected to a water pump 26 for extracting coolant.

[0060] The water pump 26 is connected to the radiator 28 through a water extraction pipe 27. The water pump 26 cooperates with the water extraction pipe 27 to extract the coolant in the radiator 28. The radiator 28 is used to cool the coolant.

[0061] A connecting pipe 29 is connected above the radiator 28, and the return pipe 24 is connected to the connecting pipe 29. The return pipe 24 and the connecting pipe 29 cooperate with each other, and with the cooperation of the water pump 26, the coolant in the serpentine tube 21 can be pumped into the radiator 28 to cool the coolant.

[0062] During specific use, by starting the water pump 26 and the radiator 28, the water pump 26 extracts the coolant in the radiator 28 through the pumping pipe 27, and with the cooperation of the liquid outlet pipe 25, the supply pipe 23 and the blocking pipe 22, the coolant is added to the serpentine tube 21, so that the LED light source can be cooled. While the water pump 26 extracts the coolant in the radiator 28, it can extract the coolant in the serpentine tube 21 through the cooperation of the connecting pipe 29, the return pipe 24 and the blocking pipe 22, and add it to the radiator 28 for cooling, so that the coolant can circulate, thereby continuously cooling the LED light source, preventing the temperature of the LED light source from rising, and improving the service life of the LED light source.

[0063] Symmetrically arranged filter plates 5 are provided on the outside of the shell 1 at positions corresponding to the cooling layer 2 , for isolating the gas generated by cooling and dust impurities, thereby preventing dust impurities from entering the shell 1 and affecting the operation of the shell 1 .

[0064] A magnetic sticker 51 is connected to one side of the filter plate 5 close to the shell 1 , and a symmetrically arranged slot 52 is provided in the shell 1 corresponding to the position of the magnetic sticker 51 . The magnetic sticker 51 is adsorbed in the slot 52 to preliminarily fix the position of the filter plate 5 .

[0065] A clamping plate 6 is provided at the position of the outer shell 1 corresponding to the filter plate 5. One end of the clamping plate 6 is in contact with the filter plate 5. The clamping plate 6 is used to press the filter plate 5 against the outside of the outer shell 1 to fix the position of the filter plate 5 and prevent the filter plate 5 from falling off or shifting.

[0066] A rotating rod 61 is connected to the middle of the splint 6, and a symmetrically arranged positioning seat 62 is connected to the position corresponding to the rotating rod 61 on the outside of the shell 1. The rotating rod 61 is rotatably connected between the positioning seats 62, and the rotating rod 61 cooperates with the positioning seats 62 to fix the position of the splint 6.

[0067] A second spring 63 is connected between the lower portion of the clamping plate 6 away from the filter plate 5 and the housing 1 for resetting the clamping plate 6 .

[0068] In specific use, after the filter plate 5 has been used for a long time, the filter holes of the filter plate 5 will be blocked by dust and impurities. In order not to affect the normal heat dissipation of the LED light source, the filter plate 5 needs to be removed for cleaning. When removing the filter plate 5, the clamping plate 6 is pressed away from one end of the filter plate 5. After pressing, the clamping plate 6 rotates under the cooperation of the rotating rod 61 and the positioning seat 62, so that the end of the clamping plate 6 close to the filter plate 5 is tilted and no longer presses the filter plate 5, so that the magnetic sticker 51 can be taken out of the card slot 52, and the filter plate 5 can be removed to clean the filter plate 5. Removing the filter plate 5 for cleaning can clean the filter plate 5 more cleanly, and dust, impurities and water will not enter the housing 1 during cleaning, and will not affect the subsequent use of the LED light source.

[0069] When the filter plate 5 needs to be installed after cleaning, press the clamping plate 6 again away from one end of the filter plate 5. After the clamping plate 6 is pressed, it will approach the shell 1 and squeeze the second spring 63. The second spring 63 will shrink under the squeezing and store the restoring force. The clamping plate 6 rotates with the cooperation of the rotating rod 61 and the positioning seat 62, so that the end of the clamping plate 6 close to the card slot 52 is tilted. At this time, the magnetic sticker 51 is placed in the position corresponding to the card slot 52, which can preliminarily fix the filter plate 5. By slowly loosening the clamping plate 6, the end of the clamping plate 6 close to the filter plate 5 is reset under the action of the second spring 63, thereby pressing the filter plate 5 again and fixing the filter plate 5. It is relatively simple to install and remove the filter plate 5, which improves efficiency.
