This equipment usually has a precise metering system that can accurately control the amount of heat dissipation mud according to different application scenarios and needs.

[0058] The double-layer alternating feeding device 100 proposed in the present application is mainly used for feeding the heat dissipation mud sheet.

[0059] The heat dissipation mud is a kind of heat dissipation material used in electronic equipment and industrial machinery, usually in paste or sheet form. It has good thermal conductivity and can effectively conduct heat from the heating components to the heat sink or other cooling devices, thereby reducing the operating temperature of the equipment. Heat dissipation mud has a wide application in the fields of electronic manufacturing, communication equipment production, automotive electronics, etc., and plays an important role in ensuring the heat dissipation performance and reliability of the equipment. In the production process, the feeding equipment of the heat dissipation mud tray can transport the heat dissipation mud sheet to the designated position in a stable and uniform manner, ensuring that the supply amount and quality of the heat dissipation mud meet the production requirements.

[0060] The heat dissipation mud feeding equipment is a device specially used for providing heat dissipation materials for electronic equipment, industrial machinery, etc. It can transport the heat dissipation mud sheet to the designated position in a stable and uniform manner, ensuring that the supply amount and quality of the heat dissipation mud meet the production requirements. This equipment usually has a precise metering system, which can accurately control the amount of heat dissipation mud according to different application scenarios and requirements. At the same time, it is also equipped with an efficient conveying mechanism, which can ensure that the heat dissipation mud does not leak, block, etc. during transportation, thereby improving production efficiency and reducing production cost. The heat dissipation mud feeding equipment has a wide application in the fields of electronic manufacturing, communication equipment production, automotive electronics, etc., and plays an important role in ensuring the heat dissipation performance and reliability of the equipment. In related technology, the heat dissipation mud feeding equipment usually has only one feeding station, and the feeding speed is slow, which cannot realize fast and stable feeding, and is not suitable for large-scale production demand.

[0061] To solve the above problems, the present application proposes a double-layer alternating feeding device 100, which aims to provide a multi-station alternating feeding device to improve the feeding rate of the heat dissipation mud sheet,Figures 1 to 12 Structure diagram of an embodiment of the double-layer alternating feeding device 100.

[0062] Referring to Figures 1 to 12 The double-layer alternating feeding device 100 comprises a rack 1, a first feeding assembly 2 and a second feeding assembly 3. The rack 1 is provided with a feeding channel 11 in a first direction, and is sequentially provided with an inlet area 1a, a first feeding area 1b and a second feeding area 1c along the extension direction of the feeding channel 11. The first feeding assembly 2 comprises a first tray 21, a first moving base 22 and a first driving mechanism 23. The first driving mechanism 23 is used to drive the first moving base 22 to reciprocate along the feeding channel 11, and the first tray 21 is carried on the first moving base 22. The first feeding assembly 2 further comprises a second tray 24, a second moving base 25 and a second driving mechanism 26. The second driving mechanism 26 is used to drive the second moving base 25 to reciprocate along the feeding channel 11, and the first tray 21 and the second tray 24 are alternately operated. The second feeding assembly 3 comprises a third tray 31, a fourth tray 33, a third moving base 32, a fourth moving base 34 and a third driving mechanism 35. The third driving mechanism 35 is drivingly connected with the third moving base 32 and the fourth moving base 34, and is used to drive the third moving base 32 and the fourth moving base 34 to move in opposite directions along the feeding channel 11. The third moving base 32 and the fourth moving base 34 are arranged in a staggered manner. The third tray 31 is carried on the third moving base 32, and the fourth tray 33 is carried on the fourth moving base 34. The first tray 21, the third tray 31 and the fourth tray 33 are arranged in a stacked manner in a second direction. The first direction and the second direction are arranged perpendicularly.

[0063] The technical scheme of the double-layer alternating feeding device 100 mainly comprises a rack 1, a first feeding assembly 2 and a second feeding assembly 3. The first feeding assembly 2 and the second feeding assembly 3 are arranged on the rack 1 and their feeding operations are independent of each other and do not interfere with each other, so as to realize double-station simultaneous feeding and improve the production rate. Specifically, the feeding channel 11 formed in the rack 1 is divided into an inlet area 1a, a first feeding area 1b and a second feeding area 1c. The inlet area 1a is the area where the staff places the tray full of the heat dissipation mud pieces in the device. The first feeding area 1b and the second feeding area 1c are the stations for the mechanical arm to take the materials.

[0064] The first feeding assembly 2 comprises a first tray 21, a first moving seat 22 and a first driving mechanism 23. The first driving mechanism 23 can drive the first moving seat 22 to move between the first feeding area 1b and the feeding area 1a. The first moving seat 22 is provided with the first tray 21. When the staff places the first tray 21 full of heat dissipation mud pieces on the first moving seat 22, the first driving mechanism 23 drives the first moving seat 22 to move along the feeding channel 11 to the first feeding area 1b. The robot arm takes all the heat dissipation mud in the first tray 21. Then, the first driving mechanism is controlled to move reversely, thereby driving the first moving seat 22 to drive the empty first tray 21 to return to the feeding area 1a. In this way, the feeding is realized. The first tray 21 and the second tray 24 are alternately fed. When the first tray 21 is in the first feeding area 1b, the second tray 24 is waiting for loading in the feeding area 1a. When the second tray 24 is in the first feeding area 1b, the first tray 21 is waiting for loading in the feeding area 1a. In this way, the feeding is realized.

[0065] The second feeding assembly 3 comprises a third tray 31, a third moving seat 32, a fourth tray 33, a fourth moving seat 34 and a third driving mechanism 35. The third driving mechanism 35 can drive the third moving seat 32 and the fourth moving seat 34 to move between the second feeding area 1c and the feeding area 1a at the same time. The third moving seat 32 and the fourth moving seat 34 are in staggered positions when feeding. When the third tray 31 is feeding in the second feeding area 1c, the fourth tray 33 is loading in the feeding area 1a. When the third tray 31 returns to the feeding area 1a after feeding, the fourth tray 33 is feeding in the second feeding area 1c. In this way, the feeding is realized.

[0066] The first feeding assembly 2 and the second feeding assembly 3 can independently complete the feeding. For example, when the third tray 31 or the fourth tray 33 is feeding in the second feeding area 1c, the first tray 21 can load in the feeding area 1a or feed in the first feeding area 1b. Moreover, the first feeding area 1b and the second feeding area 1c can feed two different kinds of heat dissipation mud pieces, so as to meet the needs of different heat dissipation mud in different positions of the downstream equipment. The production efficiency is improved, and the adaptability of the equipment is further improved.

[0067] It can be understood that the double-layer alternating feeding device 100 proposed in the present application can perform double-station feeding of the heat dissipation paste, that is, the device has two feeding positions, namely a first feeding area 1b and a second feeding area 1c. The first feeding area 1b and the second feeding area 1c are arranged vertically along the second direction, that is, they are stacked vertically. In this way, the trays of the two feeding areas do not interfere with each other, and the first feeding area 1b and the second feeding area 1c share the same loading area and are loaded with heat dissipation paste in the feeding area 1a. The first feeding area 1b and the second feeding area 1c can be equipped with two mechanical arms to pick up the heat dissipation paste pieces to supply the next process. The two mechanical arms work independently of each other. Compared with the traditional single-station single-mechanical-arm feeding, the double-station double-mechanical-arm feeding proposed in the present application can improve the feeding efficiency by one time.

[0068] In actual production applications, there are many types of heat dissipation paste, mainly due to differences in composition, performance and application scenarios. Heat dissipation paste with different compositions has different thermal conductivity, viscosity, temperature resistance range and chemical stability, etc. For example, some heat dissipation paste may contain metal powder to improve thermal conductivity, while others may add special polymers to enhance their adhesion and flexibility. In addition, different application scenarios also have different requirements for heat dissipation paste. For example, electronic devices may require low-viscosity, high-thermal-conductivity heat dissipation paste to ensure good heat dissipation effect, while automotive electronics may require heat dissipation paste that is resistant to high temperature and corrosion to adapt to harsh working environments. Therefore, there are many types of heat dissipation paste to meet various industrial needs.

[0069] Therefore, the feeding device with double stations proposed in the present application can cope with the feeding scenarios of two different types of heat dissipation paste. By setting the first feeding area 1b and the second feeding area 1c, the feeding and management are divided into two areas, and the first feeding area 1b and the second feeding area 1c do not interfere with each other. Since the first feeding area 1b uses the first tray 21 for feeding, and the second feeding area 1c uses the third tray 31 and the fourth tray 33 for feeding, the first tray 21 can be specially marked, such as using different colors or labeling on the first tray 21 to distinguish the first tray 21 from the third tray 31 and the fourth tray 33. In this way, the staff can distinguish between the two different types of heat dissipation paste pieces when loading.

[0070] This design of partitioned feeding can significantly improve production efficiency, as it allows simultaneous feeding of two different types of heat dissipation paste, reducing idle time and changing time of the device. At the same time, this design also improves the adaptability of the device, enabling it to flexibly respond to different production needs, ensuring the continuity and stability of the production process, thereby achieving higher economic benefits and production flexibility in large-scale production.

[0071] In the technical solution of the present application, the double-layer alternating feeding device 100 has two feeding states, namely a first feeding state and a second feeding state. When the double-layer alternating feeding device 100 is in the first feeding state, the third tray 31 and the third moving seat 32 in the second feeding assembly 3 are in the second feeding area 1c for feeding; the fourth tray 33 and the fourth moving seat 34 in the second feeding assembly 3 are in the feeding area 1a for manual loading; the first tray 21 and the first moving seat 22 of the first feeding assembly 2 can be in the feeding area 1a for loading, or in the first feeding area 1b for feeding, or moving between the feeding area 1a and the first feeding area 1b. Since the first feeding assembly 2 and the second feeding assembly 3 are independent of each other, the position of the first tray 21 is not limited here.

[0072] When the double-layer alternating feeding device 100 is in the second feeding state, the fourth tray 33 and the fourth moving seat 34 in the second feeding assembly 3 are in the second feeding area 1c for feeding; the third tray 31 and the third moving seat 32 in the second feeding assembly 3 are in the feeding area 1a for manual loading; the position of the first tray 21 and the first moving seat 22 in the first feeding assembly 2 is not limited as described above, and will not be repeated here.

[0073] In an embodiment of the present application, whether the device is in the first feeding state or the second feeding state, the first tray 21 and the first moving seat 22 are in the first feeding area 1b for feeding. Since the distance between the first feeding area 1b and the feeding area 1a is exactly half the distance between the second feeding area 1c and the feeding area 1a, if the running rates of the first driving mechanism 23 and the third driving mechanism 35 remain consistent, the time for the third tray 31 or the fourth tray 33 to move from the feeding area 1a to the second feeding area 1c is equal to the time for the first tray 21 to move back and forth from the feeding area 1a to the first feeding area 1b. Therefore, the first feeding area 1b and the second feeding area 1c can simultaneously and synchronously feed.

[0074] The heat dissipation mud pieces are fixed on the tray by vacuum suction, and are tightly sucked on the surface of the tray through the suction port on the tray. Specifically, when the vacuum generator works, it will suck out the air in the suction port to form a negative pressure environment lower than the atmospheric pressure. Due to the action of atmospheric pressure, the heat dissipation mud pieces are firmly pressed on the tray, thereby achieving fixation. This suction method is not only firm, but also can quickly release the heat dissipation mud pieces according to needs, facilitating quick picking and placing operations in automatic production.

[0075] Since the first tray 21, the third tray 31 and the fourth tray 33 all need to move between the feeding area and the feeding area 1a, the air pipe providing vacuum needs to be installed by a drag chain, further causing the structure of the equipment to be complex, and the consumables of the air pipe are further improved. In view of this, the present application adopts a fixed-point adsorption method to fix the heat dissipation mud pieces. Specifically, the adsorption device 4 includes a first vacuum generator 41 and a second vacuum generator 42, please further refer to Figure 2 , the first vacuum generator 41 is located in the first feeding area 1b, and the output end of the first vacuum generator 41 is driven by the pressing mechanism 5 to realize communication or disconnection with the first tray 21. When the first tray 21 moves to the first feeding area 1b, the pressing mechanism 5 drives the pressing plate 54 to descend and in the process drives the first tray 21 to press down until it is at the reference surface of the robot picking, until the first vacuum generator 41 is connected with the internal air path of the first tray 21, thereby generating a vacuum at the adsorption port, and adsorbing the heat dissipation mud pieces. When the robot picking is completed, the pressing mechanism 5 rises and is separated from the first tray 21, and the first tray 21 can return to the feeding area 1a for loading.

[0076] The second vacuum generator 42 is located in the second feeding area 1c, and the second vacuum generator 42 is always in a fixed position. When the third tray 31 or the fourth tray 33 moves to the second feeding area 1c, the jacking mechanism 6 jacks up the third tray 31 or the fourth tray 33 until the upper top surface of the third tray 31 or the fourth tray 33 is connected with the second vacuum generator 42, thereby generating a vacuum at the adsorption port of the third tray 31 or the fourth tray 33, and adsorbing the heat dissipation mud pieces.

[0077] The fixed-point adsorption method fixes the heat dissipation mud pieces, which on the one hand saves the use of air pipes and drag chains, simplifies the structure of the equipment, and reduces the complexity and maintenance cost of the equipment. On the other hand, since the vacuum generator is only turned on when the tray is located in the feeding area, the use of air source is saved, and the energy utilization efficiency is improved. This design not only reduces the consumables and energy consumption of the equipment, but also improves the reliability and operation stability of the equipment, and facilitates the rapid picking and placing operation in automatic production, further improving the production efficiency and economic benefits.

[0078] To realize the driving of the first tray 21 to descend, the present application drives through the pressing mechanism 5, specifically, please further refer to Figure 7The down-pressing mechanism 5 comprises a fixed seat 51, a third cylinder 53 and a down-pressing plate 54. The fixed seat 51 is arranged on both sides of the rack 1 and is provided with a fifth guide rail 52 along the second direction. The down-pressing plate 54 is slidingly limited on the fifth guide rail 52 and is drivingly connected with the third cylinder 53. When the third cylinder 53 is jacked up, the down-pressing plate 54 will rise, and vice versa. The output end of the first vacuum generator 41 is communicated with the down-pressing plate 54. The down-pressing plate 54 is hollow designed and forms a plurality of air paths, which are respectively connected with a plurality of air inlets of the first tray 21 to realize the generation of vacuum adsorption force. The first tray 21 and the second tray 24 share the first vacuum generator 41 to realize the adsorption and fixation of the heat dissipation mud in the tray.

[0079] In an embodiment of the present application, please further refer to Figure 3 One side of the rack 1 is provided with a first guide rail 12. The first moving seat 22 is slidingly arranged on the first guide rail 12. The first driving mechanism 23 is used to drive the first moving seat 22 to move along the first guide rail 12. The first driving mechanism 23 comprises a first motor 231, a first driven wheel 232 and a first transmission belt 233. The two ends of the first transmission belt 233 are respectively sleeved on the output end of the first motor 231 and the first driven wheel 232. The first moving seat 22 is connected with the first transmission belt 233. The driving principle of the first moving seat 22 is based on the transmission belt driving system. Specifically, the first motor 231 serves as a power source. Its output end is connected with the first driven wheel 232 through the first transmission belt 233. When the first motor 231 is started, it drives the first driven wheel 232 to rotate through the first transmission belt 233. Since the first moving seat 22 is connected with the first transmission belt 233, the movement of the first transmission belt 233 will be directly transmitted to the first moving seat 22, so that the first moving seat 22 reciprocates along the first guide rail 12. The first tray 21 is fixed on the first moving seat 22. Therefore, the movement of the first moving seat 22 will drive the first tray 21 to move in the feeding channel 11 from the feeding area 1a to the first feeding area 1b and then return to the feeding area 1a. This driving mode ensures the stable and accurate movement of the first tray 21 and meets the automation requirement of the feeding equipment. The side of the rack 1 opposite to the first guide rail 12 is provided with a second guide rail 13. Specifically, please further refer to Figure 5 The second moving seat 25 is slidingly arranged on the second guide rail 13. The second driving mechanism 26 comprises a second motor 261, a second driven wheel 262 and a second transmission belt 263. The two ends of the second transmission belt 263 are respectively sleeved on the output end of the second motor 261 and the second driven wheel 262. The second moving seat 25 is fixed on the second transmission belt 263 and can be driven by the second transmission belt 263 to move along the second guide rail 13. The movements of the first tray 21 and the second tray 24 are independent of each other and are realized by two sets of driving mechanisms.

[0080] To simplify the manufacturing and assembly costs of the device, the driving forms of the third tray 31 and the fourth tray 33 are consistent with the first tray 21. Specifically, please further refer to Figure 6 The side of the rack 1 facing away from the first guide rail 12 is provided with a third guide rail 14 and a fourth guide rail 15 stacked in the second direction, the third moving seat 32 is slidingly arranged on the third guide rail 14, and the fourth moving seat 34 is slidingly arranged on the fourth guide rail 15; the third driving mechanism 35 includes a third motor 351, a third driven wheel 352, and a third transmission belt 353, the two ends of the third transmission belt 353 are respectively sleeved on the output end of the third motor 351 and the third driven wheel 352, and the third moving seat 32 and the fourth moving seat 34 are respectively connected to the upper and lower sides of the third transmission belt 353 to realize reverse motion.

[0081] The driving principle of the third moving seat 32 and the fourth moving seat 34 is based on a double transmission belt driving system. Specifically, the third motor 351 serves as a power source, and its output end is connected to the third driven wheel 352 through the third transmission belt 353. When the third motor 351 starts, it drives the third driven wheel 352 to rotate through the third transmission belt 353. Since the third moving seat 32 and the fourth moving seat 34 are respectively connected to the upper and lower sides of the third transmission belt 353, the movement of the third transmission belt 353 will be transmitted to these two moving seats, causing them to move in opposite directions along the third guide rail 14 and the fourth guide rail 15. The third tray 31 and the fourth tray 33 are respectively fixed on the third moving seat 32 and the fourth moving seat 34, so the movement of these two moving seats will drive the third tray 31 and the fourth tray 33 to move within the feeding channel 11 from the feeding area 1a to the second feeding area 1c and then return to the feeding area 1a. This design ensures the smooth and precise movement of the third tray 31 and the fourth tray 33, while achieving reverse motion, improving feeding efficiency and the adaptability of the device.

[0082] To ensure that the feeding positions of the first feeding area 1b and the second feeding area 1c are consistent, and to facilitate the two robotic arms to use the same reference surface as the working reference for picking up the material pieces, the third tray 31 or the fourth tray 33 in the second feeding area 1c will be lifted by the lifting mechanism 6 to a position parallel to the first tray 21, so that the trays in the first feeding area 1b and the second feeding area 1c are in parallel positions, facilitating the robotic arms to pick up. In addition, the pressing mechanism 5 will lower the first tray 21 until it is parallel to the third tray 31 or the fourth tray 33. The lifting mechanism 6 includes a mounting seat 61, a first air cylinder 63, and a lifting plate 64. Specifically, please further refer to Figure 8The mounting seat 61 is mounted in the feeding channel 11, the first cylinder 63 is arranged on the mounting seat 61 and can move in the second direction, the mounting seat 61 movably has four guide rods 62, the four guide rods 62 are arranged at four corners of the mounting seat 61 respectively and are connected with the bottom surface of the jacking plate 64, when the first cylinder 63 extends, the jacking plate 64 is driven to move upward along the second direction until abuts against the third tray 31 or the fourth tray 33, the first cylinder 63 continuously moves to lift the third tray 31 or the fourth tray 33 away from the moving seat until moving to a preset position, at this time, the upper top surface of the third tray 31 or the fourth tray 33, that is, the surface for placing the heat dissipation mud piece, is coplanar with the upper top surface of the first tray 21.

[0083] In this way, the two mechanical arms can pick up the heat dissipation mud with the same reference surface, reducing the adjustment time and errors caused by inconsistent tray positions. Secondly, this design enhances the stability and reliability of the equipment, reducing mechanical failures or operation errors that may be caused by tray position deviation. In addition, it also improves the adaptability and flexibility of the equipment, better meeting the feeding needs of different types and sizes of heat dissipation mud pieces, thereby achieving more efficient and stable production processes in complex production environments.

[0084] To avoid sudden power failure or air failure of the first cylinder 63 of the jacking mechanism 6, causing the third tray 31 or the fourth tray 33 to fall down, causing damage to the equipment, the jacking mechanism 6 further includes a fall prevention mechanism 65, specifically, please further refer to Figure 8 The fall prevention mechanism 65 includes a second cylinder 651, the movable end of the second cylinder 651 is arranged towards one of the guide rods 62, and the movable end of the second cylinder 651 is movably arranged on the movement path of the guide rod 62. The fall prevention mechanism 65 prevents the jacking plate 64 from accidentally falling due to sudden power failure or air failure of the first cylinder 63, thereby protecting the equipment from damage. Specifically, the movable end of the second cylinder 651 is arranged towards one of the guide rods 62, and the movable end is located on the movement path of the guide rod 62. When the first cylinder 63 is working normally, the second cylinder 651 is in a retracted state and does not interfere with the normal movement of the jacking plate 64. When the third tray 31 or the fourth tray 33 rises to a preset position, the movable end of the second cylinder 651 will extend and insert into the movement path of the guide rod 62. Once the first cylinder 63 loses power due to power failure or air failure, the jacking plate 64 begins to fall, and the second cylinder 651 prevents the jacking plate 64 from continuing to fall. This design ensures that the third tray 31 or the fourth tray 33 will not fall down even in the event of a sudden failure, thereby effectively protecting the safety and stability of the equipment.

[0085] In this embodiment, the third tray 31 or the fourth tray 33 is driven to move to a preset position by the jacking mechanism 6 to realize feeding, however, there may be a certain error in the movement stroke of the first cylinder 63, thereby causing overtravel, so that the third tray 31 or the fourth tray 33 is in two horizontal planes with a height difference from the first tray 21, which affects the material taking of the mechanical arm. In view of this, the limiting plate 9 is arranged on both sides of the rack 1, and please further refer to Figure 1 The limiting plate 9 arranged on both sides of the rack 1 can effectively limit the movement stroke of the first cylinder 63 to prevent overtravel caused by stroke error. In this way, the limiting plate 9 ensures that the third tray 31 or the fourth tray 33 can be accurately in the same horizontal plane as the first tray 21 when jacked to the preset position, avoiding the influence of the height difference on the material taking operation of the mechanical arm. This design not only improves the operation accuracy and reliability of the equipment, but also enhances the stability of the production process, reduces the production interruption caused by mechanical failure or operation error, and improves the overall production efficiency and service life of the equipment.

[0086] When the first tray 21, the third tray 31 and the fourth tray 33 are located in the feeding area 1a, they also have two position states, when the tray is in the first position state, the tray is in the state of waiting for loading; when the tray is in the second position state, the tray is in the state of waiting for taking out the loading, and the worker can take out the tray for loading. In the technical solution of the present application, only one tray is in the second position state for loading each time, and the other trays are located in the loading area or in the first position state. In order to avoid mistaken taking out by the worker, the locking mechanism 7 is further arranged in the feeding area 1a, and please further refer to Figure 10 The locking mechanism 7 is arranged on the rack 1 and includes a plurality of locking cylinders 71, which are arranged in a stack along the second direction and are installed by the mounting vertical plate 72; the side of the first tray 21, the third tray 31 and the fourth tray 33 close to the locking mechanism 7 is provided with a matching hole, and the locking cylinder 71 is inserted or separated from the matching hole. The locking mechanism 7 is inserted or separated from the matching hole on the side of the first tray 21, the third tray 31 and the fourth tray 33 by the plurality of locking cylinders 71 to control the movement state of the tray. When the tray is in the first position state (waiting for loading state), the piston of the locking cylinder 71 is extended to insert into the matching hole on the tray to fix the tray in the feeding area 1a, preventing it from being mistakenly taken out. When it is necessary to move the tray to the second position state (waiting for taking out the loading state), the piston of the locking cylinder 71 is retracted to separate from the matching hole, thereby releasing the tray to allow the worker to take it out for loading. This design ensures that only one tray is in the state of being taken out each time, avoids the mistaken operation of the worker, and improves the operation efficiency and safety of the equipment.

[0087] The locking mechanism 7 can effectively prevent the operator from mistakenly taking out the tray in the waiting loading state, ensuring that only one tray is in a removable state at a time. This design improves the safety of the equipment operation, avoids production interruptions or equipment damage caused by misoperation. At the same time, it also optimizes the production process, improves production efficiency, and ensures the stable operation of the feeding equipment.

[0088] It should be noted that in addition to the locking mechanism of the locking cylinder 71 and the matching hole used in this embodiment, other locking mechanisms can also be used to achieve similar functions. For example, an electromagnetic lock can be used to fix the tray in the feeding area 1a through electromagnetic force; or a mechanical locking device such as a latch or a buckle can be used to lock the tray in a specific position through physical means. In addition, sensors and control systems can also be used to automatically trigger locking or unlocking actions when detecting that the tray is in a specific state. These different locking methods can be selected and designed according to specific application scenarios and equipment requirements to achieve the best locking effect and operational convenience.

[0089] When the operator takes away the tray for loading, to avoid the tray being loaded in reverse, causing subsequent loading process defects, the double-layer alternating feeding equipment 100 also includes a position detection device 8. For details, please refer to Figure 10 , the position detection device 8 includes a laser sensor 81 and a displacement sensor, the displacement sensor can detect the position of the four-layer tray, the laser sensor 81 is arranged on the rack 1; the first moving seat 22, the second moving seat 25, the third moving seat 32 and the fourth moving seat 34 are respectively provided with first avoidance holes 221, the first tray 21, the second tray 24, the third tray 31 and the fourth tray 33 are respectively provided with second avoidance holes 211, and the laser 8a emitted by the laser sensor 81 is emitted through the first avoidance hole 221 and the second avoidance hole 211. The working principle of the displacement sensor is to detect whether the tray is placed in reverse by measuring the distance of the bottom of each tray. Specifically, the displacement sensor stores the position of each layer of tray, if the tray is placed in reverse on the moving seat, due to the foolproof structure, the tray will be placed inclined on the moving seat, and when the displacement sensor detects the position of the tray again, the stored position information is inconsistent, then the tray is placed in reverse; otherwise, the tray is placed correctly. The displacement sensor can detect whether the first tray 21, the second tray 24, the third tray 31 and the fourth tray 33 are placed correctly.

[0090] The working principle of the in-place detection device 8 is to use the laser 8a emitted by the laser sensor 81 to detect whether the tray is correctly installed in place through the first avoidance hole 221 on the moving seat and the second avoidance hole 211 on the tray. When the tray is correctly installed, the laser 8a can smoothly pass through the first avoidance hole 221 and the second avoidance hole 211, and the sensor receives a complete infrared signal, indicating that the sheet has not been placed. If the sheet has been correctly placed, the laser 8a will be blocked and the sensor will not be able to receive a complete signal. This detection method can quickly and accurately determine the installation state of the tray and ensure the normal operation of the feeding equipment. By using the laser sensor 81, the problem of incorrect installation or incorrect installation of the tray can be effectively avoided. This detection method can quickly and accurately determine the installation state of the tray and ensure the correct placement of the tray in the feeding equipment. Once an installation error is detected, the system can immediately issue an alarm or stop operation, thereby preventing subsequent feeding processes from being affected due to improper installation of the tray, reducing production errors and equipment failures, and improving production efficiency and equipment reliability.

[0091] In addition to the laser sensor 81, other sensors or detection methods can also be used to detect the installation state of the tray. For example, a photoelectric sensor can be used to detect whether the tray is correctly installed by detecting the reflection or transmission of light; a magnetic sensor can be used to detect the position and direction of the tray by detecting the magnetic mark on the tray; in addition, a mechanical limit switch can be used to detect whether the tray has reached the predetermined position by physical contact. These alternative methods can be selected according to specific application requirements and equipment design to achieve the best detection effect and operational convenience.

[0092] According to the double-layer alternating feeding device 100 described above, the application also proposes an alternating feeding method, which specifically includes the following steps: S1: First, the staff places the tray full of heat dissipation mud pieces in the first position state of the feeding area 1a and fixes it through the locking cylinder 71 of the locking mechanism 7 to prevent mistaken removal. S2: When feeding is needed, the locking cylinder 71 retracts to release the tray, and then the first driving mechanism 23 starts to drive the first moving seat 22 to move along the first guide rail 12, moving the first tray 21 from the feeding area 1a to the first feeding area 1b. S3: After reaching the first feeding area 1b, the suction device 4 is lowered to communicate with the first tray 21 through the lowering mechanism 5, generating vacuum adsorption of the heat dissipation mud pieces, and then the mechanical arm picks up the heat dissipation mud pieces from the first feeding area 1b for subsequent operation. S4: After the mechanical arm completes the material taking, the lowering mechanism 5 rises to disengage from the first tray 21, and the first driving mechanism 23 reverses to move the first moving seat 22 and the first tray 21 back to the feeding area 1a, preparing for the next feeding. S5: At the same time, the second feeding assembly 3 starts to work, the third driving mechanism 35 starts to drive the third moving seat 32 and the fourth moving seat 34 to move reversely along the third guide rail 14 and the fourth guide rail 15, and when the third tray 31 or the fourth tray 33 moves to the second feeding area 1c, the jacking mechanism 6 jacks up to a position parallel to the first tray 21, the suction device 4 of the second feeding area 1c communicates with the jacked tray to generate vacuum adsorption of the heat dissipation mud pieces, and the mechanical arm picks up the heat dissipation mud pieces from the second feeding area 1c for subsequent operation. S6: After the mechanical arm completes the material taking, the jacking mechanism 6 lowers, the third tray 31 or the fourth tray 33 disengages from the jacking plate 64, and the third driving mechanism 35 reverses to move the third moving seat 32 and the fourth moving seat 34 back to the feeding area 1a, preparing for the next feeding. S7: By repeating the above steps, the alternating feeding of the first feeding assembly 2 and the second feeding assembly 3 is realized, ensuring the continuity and efficiency of the production process.

[0093] The first feeding assembly 2 and the second feeding assembly 3 mentioned in the above method are independent of each other and do not interfere with each other, significantly improving the running efficiency and flexibility of the feeding device. This design allows both feeding assemblies to operate simultaneously, one assembly feeding in the feeding area while the other assembly loading in the feeding area 1a, thereby realizing double-station simultaneous feeding, reducing idle time and reloading time of the device. In addition, this independence also enhances the reliability of the device, even if one of the assemblies fails, the other assembly can still continue to work, ensuring the continuity of the production process. At the same time, it also improves the adaptability of the device, which can flexibly respond to the feeding needs of different types of heat dissipation mud, meet the production requirements of different positions of downstream equipment, and thus achieve higher economic benefits and production efficiency in large-scale production.

[0094] The above merely illustrates the embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, within the technical concept of the present application, and based on the content of the present application and the accompanying drawings, are included in the patent protection scope of the present application.
