[0027] See also Figures 1 to 4 An embodiment of the present application provides a hooking structure 100 and a sintering device having the same. The hooking structure 100 is used to move a material tray 200 on a material bin 202, or to move the material tray 200 to the material bin 202. The material tray 200 is provided with semiconductor devices to be sintered, or semiconductor devices that have been sintered.

[0028] See also Figures 1 to 3 The hooking structure 100 is used to hook the material tray 200 from a predetermined position, and a clamping portion 201 is provided at one end of the material tray 200, or to move the material tray 200 with the sintered semiconductor devices placed thereon to a predetermined position. In this embodiment, the predetermined position is a material bin 202 for receiving the material tray 200.

[0029] The hook structure 100 includes: a hook plate 10 slidingly arranged relative to a predetermined position, a loading rack 11 located on the sliding path of the hook plate 10, and a driving component 20 for driving the hook plate 10 to reciprocate along a predetermined direction; in this embodiment, the predetermined direction is a horizontal direction, and the hook plate 10 can perform linear reciprocating movement under the action of external force.

[0030] See also Figures 1 to 3The hook plate 10 has a first position 101 and a second position 102. When the drive assembly 20 drives the hook plate 10 toward a predetermined position and places the hook plate 10 in the first position 101, the hook plate 10 is detachably connected to the clamping portion 201; that is, one end of the hook plate 10 is engaged with the clamping portion 201. The drive assembly 20 drives the hook plate 10 to move away from the predetermined position and into the second position 102. The material tray 200 is synchronously moved and slides to the material carrier 11, and the hook plate 10 is disengaged from the material tray 200, thereby completing the movement of the material tray 200 and achieving the loading of the material tray 200. It is understood that the reverse process of the above process can achieve the movement of the material tray 200 from the material carrier 11 to the predetermined position, that is, the material tray 200 moves from the material carrier 11 to the material bin 202, thereby achieving the unloading of the material tray 200.

[0031] See also Figures 1 to 3 The hook structure 100 provided in the present application can precisely control the movement and connection of the hook plate 10 by providing a driving assembly 20, so that the material tray 200 can be smoothly moved from a predetermined position to the material carrier 11 under the pull of the hook plate 10, and ensure stability and safety during the movement. At the same time, through the detachable connection between the hook plate 10 and the clamping portion 201, after the material tray 200 is located on the material carrier 11, the material tray 200 can be disconnected from the hook plate 10, which facilitates the subsequent operation of the material tray 200 by the robot, thereby realizing automatic loading of the material tray 200 and improving the flexibility and convenience of the overall operation. It also improves the degree of automation, reduces manual operation, improves work efficiency, and improves the continuity and stability of the production process.

[0032] Optionally, a clamping portion 201 is provided at both opposite ends of the material tray 200 .

[0033] In some embodiments, the drive assembly 20 includes a bracket 22 that slides along a predetermined direction and a movable actuator 21 that drives the bracket 22 to slide back and forth. The hook plate 10 is connected to the bracket 22. The movable actuator 21 can be a pneumatic cylinder or a rodless cylinder, which is not limited here and can be selected according to actual circumstances.

[0034] See also Figures 1 to 3 Optionally, the combination of bracket 22 and movable actuator 21 allows the hook plate 10 to slide smoothly in a predetermined direction, ensuring smooth and precise handling of the tray 200 during hooking and release. The presence of bracket 22 makes the entire structure more stable and robust, capable of withstanding heavy loads, and enhancing the reliability and durability of the equipment. Furthermore, the use of movable actuator 21 provides a high degree of automation throughout the entire operation, significantly reducing human intervention and improving production efficiency and operational safety.

[0035] See also Figures 1 to 3In some embodiments, the hook plate 10 is rotated to connect the bracket 22, and the driving assembly 20 further includes a rotation driver 25 connected to the bracket 22 and used to drive the hook plate 10 to rotate. When the hook plate 10 is located at the first position 101, the rotation driver 25 drives the hook plate 10 to rotate so that the hook plate 10 is buckled into the clamping portion 201; when the hook plate 10 is located at the second position 102, the rotation driver 25 drives the hook plate 10 to rotate in the opposite direction so that the hook plate 10 is disengaged from the clamping portion 201.

[0036] See also Figures 1 to 3 The rotation driver 25 can be a cylinder, which drives the hook plate 10 to rotate clockwise and upward by a predetermined angle, such as 5 degrees or 15 degrees, so that the hook plate 10 is hooked to the clamping part 201, thereby realizing the connection between the hook plate 10 and the material tray 200; or the rotation driver drives the hook plate 10 to rotate counterclockwise and downward by a predetermined angle, so that the hook plate 10 is disengaged from the clamping part 201, thereby releasing the connection with the material tray 200.

[0037] Optionally, by adding a rotary actuator 25, the hook plate 10 can be flexibly rotated between different positions, achieving automatic engagement and disengagement between the hook plate 10 and the engaging portion 201. This not only improves operational precision and efficiency, but also reduces mechanical wear and extends the life of the device. Furthermore, the use of the rotary actuator 25 allows the hook plate 10 to rotate smoothly between the first position 101 and the second position 102, improving stability and safety during the process of hooking and releasing the material tray 200.

[0038] See also Figures 1 to 3 In some embodiments, the hook plate 10 includes a plate body 12 rotatably connected to a bracket 22 and a buckle plate 13 provided at one end of the plate body 12. The other end of the plate body 12 is rotatably connected to a rotation driver 25. The clamping portion 201 is a clamping hole opened on the material tray 200, and the buckle plate 13 is adapted to the shape of the clamping hole.

[0039] Optionally, by adapting the buckle plate 13 to the clamping portion 201, a secure buckling effect can be achieved between the hook plate 10 and the material tray 200. The adaptive design of the buckle plate 13 and the shape of the clamping hole ensures the stability and reliability of the material tray 200 during the hooking and releasing process, and avoids the risk of the material tray 200 falling off or slipping.

[0040] See also Figures 1 to 3 In some embodiments, a transfer hole 14 is opened at one end of the plate body 12 , a rotating shaft 251 is provided in the transfer hole 14 , and the output shaft of the rotation driver 25 is connected to the rotating shaft 251 .

[0041] Optionally, by providing an adapter hole 14 in the plate body 12 and disposing a rotation shaft 251 within the adapter hole 14, the hook plate 10 can rotate more stably and smoothly, reducing mechanical friction and wear and improving the durability of the device. The connection between the output shaft of the rotary driver 25 and the rotation shaft 251 ensures effective transmission of driving force, allowing the hook plate 10 to rotate flexibly and achieve precise engagement and disengagement operations.

[0042] See also Figures 1 to 3 In some embodiments, the shape of the adapter hole 14 is elliptical, circular, polygonal or racetrack.

[0043] Alternatively, by designing the adapter hole 14 into an elliptical, circular, polygonal, or racetrack shape, the rotation shaft 251 can achieve greater flexibility and adaptability during rotation, further improving the smoothness and precision of the rotation of the hook plate 10. Adapter holes 14 of different shapes can adapt to different rotation requirements, increasing the diversity and flexibility of rotation.

[0044] Optionally, in this embodiment, the shape of the adapter hole 14 is a runway shape. In other embodiments, the shape of the adapter hole 14 may also be an ellipse. There is no limitation here and the shape can be selected according to actual conditions.

[0045] See also Figures 1 to 3 In some embodiments, the drive assembly 20 further includes a guide rail 23 arranged along a predetermined direction and a slider 24 slidably connected to the guide rail 23, and the bracket 22 is connected to the slider 24. The predetermined direction is a horizontal direction, and the length direction of the guide rail 23 is consistent with the predetermined direction.

[0046] Optionally, by adding a guide rail 23 and a slider 24, the bracket 22 can slide smoothly in a predetermined direction, improving the stability and precision of the hook plate 10 during movement. The provision of the guide rail 23 makes the entire structure more stable, capable of withstanding heavy loads, and enhancing the reliability and durability of the device. The sliding connection between the slider 24 and the guide rail 23 ensures smooth movement of the bracket 22, reduces mechanical friction and wear, and extends the service life of the device.

[0047] See also Figures 1 to 3 In some embodiments, the loading rack 11 includes two oppositely arranged loading vertical plates 111, the hook plate 10 is located between the two loading vertical plates 111, and a loading groove 112 is opened on any loading vertical plate 111, and the two ends of the material tray 200 are respectively slidably set in the two loading grooves 112.

[0048] Optionally, the carrier 11 includes two opposing loading plates 111, allowing the tray 200 to slide and support more stably, preventing the risk of tilting or falling. The loading trough 112 on the loading plates 111 allows the tray 200 to slide smoothly onto the carrier 11. The loading trough 112 also holds the tray 200 in place, improving operational stability and reliability. The hook plate 10, located between the two loading plates 111, ensures the stability and safety of the tray 200 during movement, reducing mechanical wear and operational errors.

[0049] See also Figures 1 to 3 In some embodiments, the loading trough 112 is provided with a guide surface 113 for guiding the material tray 200 to slide in.

[0050] Optionally, by providing a guide surface 113 on the loading trough 112, one end of the tray 200 can slide smoothly into the loading trough 112, thereby improving the convenience and efficiency of operation. The guide surface 113 can effectively reduce the friction and resistance during the sliding process of the tray 200, thereby preventing the tray 200 from getting stuck or slipping.

[0051] The present invention also proposes a sintering device, which includes a hooking structure 100. The specific structure of the hooking structure 100 refers to the above embodiment. Since the present sintering device adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

The sintering apparatus further includes a lifting structure 203 for vertically elevating the silo 202. Thus, after the previous material tray 200 is removed, the lifting structure 203 drives the silo 202 to rise a certain distance, allowing the next material tray 200 to be ready for removal, thereby achieving continuous material loading.

[0053] By integrating the material hooking structure 100 into the sintering equipment, the equipment can achieve automated and continuous material tray 200 hooking and release operations, improving production efficiency and operational convenience.
