[0037] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a drying machine grain box plate welding platform exchange mechanism, which includes a frame 100, a sliding frame 200, a lifting drive mechanism 300, a lifting platform 400 and a horizontal platform 500.

[0038] The sliding frame 200 is slidably mounted on the frame 100, the frame 100 is provided with a slide rail, and the sliding frame 200 is provided with a slider adapted to the slide rail, so as to achieve sliding guidance. The sliding frame 200 is connected to a first sliding drive mechanism 210 for driving it to slide; the sliding direction of the sliding frame 200 is the front-back direction.

[0039] The lifting drive mechanism 300 is installed on the sliding frame 200, and the lifting drive mechanism 300 is provided with a telescopic push rod 310 capable of lifting and lowering. The lifting drive mechanism 300 can be specifically a cylinder or a hydraulic cylinder.

[0040] The lifting platform 400 has a low position and a high position. The lifting platform 400 is connected to the telescopic push rod 310 to realize lifting activities and thus realize the switching between the low position and the high position. The lifting drive mechanism 300 drives the telescopic push rod 310 to lift and lower the lifting platform 400 to realize the switching between the low position and the high position. The sliding frame 200 can slide to drive the lifting platform 400 to move, thereby realizing the lifting and lowering and horizontal movement of the lifting platform 400.

[0041] The horizontal platform 500 can be movably mounted on the frame 100 and can shuttle under the lifting platform 400 in a high position. The sliding direction of the horizontal platform 500 is the same as that of the sliding frame 200. The lifting platform 400 and the horizontal platform 500 are both used to position and fix metal structural parts to facilitate subsequent robot precision welding. From this perspective, the lifting platform 400 and the horizontal platform 500 can be understood as structures with the same function.

[0042] A dryer grain box plate welding platform exchange mechanism in a preferred embodiment provided by the present invention realizes the automation and continuity of welding operations by adopting the dryer grain box plate welding platform exchange mechanism, reduces the manual transfer link, significantly improves production efficiency, and adapts to the needs of mass production. Compared with the traditional circular rotary conveying method, the dryer grain box plate welding platform exchange mechanism of the present patent is compact in design, effectively reduces the floor space of the production line, makes the factory space utilization more reasonable, and reduces production costs. By using the lifting drive mechanism 300 to drive the lifting platform 400 to rise, the horizontal platform 500 and the lifting platform 400 can be staggered in the height direction, so that the movement of the two does not interfere, so that the lifting platform 400 and the horizontal platform 500 can shuttle and exchange positions, so that there is no need for a circular conveying line to transport the lifting platform 400 and the horizontal platform 500, and the lifting platform 400 and the horizontal platform 500 can also be circulated through linear activities, reducing the floor space of the equipment.

[0043] Usually, the whole dryer grain box plate welding platform exchange mechanism has three or more stations. In order to facilitate understanding of the working principle of the embodiment of the present invention, one of the working processes of the dryer grain box plate welding platform exchange mechanism with three stations is described below. In the initial state, the horizontal platform 500 is in the middle station, the previous station of the middle station is the machine loading station, and the next station is the automatic welding station. The machine loading station and the automatic welding station are both stations operated by machines and equipment, and manual entry is not allowed. The middle station is a manual loading station, where small parts are manually placed on large parts loaded by the machine loading station. When the horizontal platform 500 is in the middle position, if the lifting platform 400 is in the automatic welding position and the welding has been completed, and the welded workpiece has been taken away, the lifting platform 400 needs to move to the machine loading position for the next loading. However, the horizontal platform 500 is blocked in the middle position at this time, and it is not convenient to return directly to the machine loading position. At this time, manual work needs to be temporarily suspended, and the lifting drive mechanism 300 drives the lifting platform 400 to rise, so that the horizontal platform 500 and the lifting platform 400 can be staggered in the height direction, so that the movement of the two does not interfere with each other, and the lifting platform 400 can move from the horizontal platform 500 back to the machine loading position without being affected by the interference of the horizontal platform 500, thereby realizing the circular transportation of the lifting platform 400.

[0044] Reference Figure 4 and Figure 6 In some embodiments of the present invention, the sliding frame 200 is installed on the left side of the frame 100, and the auxiliary lifting mechanism 600 is provided on the right side of the lifting platform 400. The auxiliary lifting mechanism 600 is used to drive the corresponding side of the lifting platform 400 to lift and lower, thereby realizing lifting and lowering on both sides, making the lifting and lowering more stable. The sliding frame 200 and the auxiliary lifting mechanism 600 are arranged on the left and right to facilitate the horizontal platform 500 to pass through the middle.

[0045] Reference Figure 5 and Figure 7In a further embodiment of the present invention, the auxiliary lifting mechanism 600 includes a swing rod 610 and a telescopic driving mechanism 620; the middle part of the swing rod 610 is hinged to the right side of the lifting platform 400. Specifically, a hinge block 430 is provided on the right side of the lifting platform 400 for the middle part of the swing rod 610 to be hinged. A first roller 611 is installed at one end of the swing rod 610, and the other end is hinged to one end of the telescopic driving mechanism 620. The other end of the telescopic driving mechanism 620 is hinged to the right side of the lifting platform 400. The telescopic driving mechanism 620 is a telescopic cylinder or a telescopic oil cylinder. One end of the telescopic driving mechanism 620 is hinged to the swing rod 610 through a hinge shaft, and the other end is hinged to the lifting platform 400 through a hinge shaft. The frame 100 is provided with a first guide rail 110 extending along the sliding direction of the sliding frame 200. The first roller 611 in the low position state and the high position state cooperates with the first guide rail 110 to achieve active guidance. When the lifting platform 400 needs to rise, the telescopic driving mechanism 620 extends outward, driving the end of the swing rod 610 away from the first roller 611 and the middle of the swing rod 610 to rise, thereby driving the lifting platform 400 to rise. Figure 6 and Figure 7 The first roller 611 is used to roll on the first guide rail 110 to achieve support and movement of the right side of the lifting platform 400.

[0046] Reference Figure 5 and Figure 6 In a further embodiment of the present invention, a second roller 510 is provided on the right side of the horizontal platform 500, and the frame 100 is provided with a second guide rail 120 that cooperates with the second roller 510. The first guide rail 110 and the second guide rail 120 are staggered in the left-right direction, and the second guide rail 120 is located inside the first guide rail 110, so as to avoid structural interference when the horizontal platform 500 passes through the bottom of the lifting platform 400. The first guide rail 110 and the second guide rail 120 both extend in the front-back direction.

[0048] Reference Figure 7In a further embodiment of the present invention, the auxiliary lifting mechanism 600 is provided with multiple groups along the sliding direction (front-rear direction) of the sliding frame 200, so as to achieve multi-position support. It is understandable that the second roller 510, the third roller 520 and the fourth roller 410 are all provided with multiple intervals along the front-rear direction to achieve multi-position stable support.

The first sliding drive mechanism 210 is a motor, and the output shaft of the motor is directly connected to the first driving gear or is connected to the first driving gear through a reduction mechanism. The first sliding drive mechanism 210 drives the first driving gear to rotate, and under the cooperation of the first driving gear and the first spur rack 140, the sliding frame 200 is driven to move along the first spur rack 140, thereby realizing the movable drive of the sliding frame 200.

[0050] Reference Figure 2 In a further embodiment of the present invention, a slide 530 is installed at the middle bottom of the horizontal platform 500 in the left-right direction to avoid the structure on the left and right sides of the lifting platform 400. A second sliding drive mechanism 540 is installed on the slide 530. The second sliding drive mechanism 540 is connected to a second driving gear. A second spur rack 150 meshing with the second driving gear is installed on the frame 100. The second spur rack 150 extends in the front-to-back direction. The second sliding drive mechanism 540 is a motor. The motor drives the second driving gear to rotate, and then the cooperation between the second driving gear and the second spur rack 150 is used to drive the horizontal platform 500 to move forward and backward. A slider is provided on the slide 530, and the frame 100 is provided with a slide rail adapted to the slider, so as to realize the guidance of the slide 530 sliding forward and backward and improve the sliding stability.
