Description

Technical Field

[0002] Smart factories represent a new phase in the development of modern factory informatization. Building on the foundation of digital factories, they leverage IoT and equipment monitoring technologies to enhance information management and services. Currently, the manufacturing industry is rapidly transitioning from mechanization to automation. Simultaneously, with the development of intelligent technologies, smart manufacturing is also showing a trend of replacing automated manufacturing. However, in smart manufacturing workshops, transfer vehicles are still needed to transport items that cannot be transported by automated equipment.

[0003] In the prior art, for example, Chinese patent publication number CN217575296U proposes a multifunctional transfer vehicle for use in intelligent manufacturing workshops. A motor cooperates with a threaded rod to drive a threaded sleeve and a push rod. The push rod cooperates with a push block to squeeze a push rod against a positioning shell. Simultaneously, the left side of the storage shell moves upward, tilting the storage shell. The contents are then discharged through an outlet on the right side, thereby improving the efficiency of the transfer vehicle. However, in this technical solution, because the outlet of the storage shell is at a certain height from the ground, the contents may be damaged when being dumped. Summary of the Invention

The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with examples.

[0019] like Figure 1 As shown, the present invention proposes an intelligent transfer vehicle for intelligent manufacturing workshops, including a chassis 1, an outer frame 4 and a carrier plate 5. The chassis 1 includes a front mounting plate 13, a rear frame 12 and two connecting beams 11 for connecting the mounting plate 13 and the rear frame 12; wherein the two connecting beams 11 are arranged parallel to each other and fixedly connected between the mounting plate 13 and the rear frame 12. The left and right sides of the bottom of the mounting plate 13 are respectively provided with front wheels 2, and the left and right sides of the bottom of the rear frame 12 are respectively provided with rear wheels 3. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, two outer frames 4 extending parallel to each other in a direction away from the upper surface of the mounting plate 13 are provided on the upper surface of the mounting plate 13, and a carrier plate 5 is provided between the two outer frames 4; the left and right sides of the front end of the carrier plate 5 are respectively connected to the front sides of the left and right side walls of the outer frames 4 by rotating shafts; the outer frames 4 are located between the two connecting beams 11; the left and right sides of the front end of the carrier plate 5 are respectively connected to the left and right connecting beams 11 in a sliding manner along the front-to-back direction. Figures 1-4 As shown, the mounting plate 13 is provided with a lifting mechanism capable of driving the outer frame 4 to move up and down. Figures 1-4 As shown, the lifting mechanism includes a motor 6, a driving gear 61, a driven gear 100, a driving gear 9, and two lifting racks 140; wherein the two lifting racks 140 are fixed on the left and right sides of the outer side surface of the front side wall of the outer frame 4; the motor 6 is fixedly mounted on the mounting plate 13 through a mounting bracket 14, and the power output shaft of the motor 6 is provided with a driving gear 61. A rotating shaft 8 is rotated on the mounting bracket 14, and a driven gear 100 is provided in the middle of the rotating shaft 8; the driven gear 100 is meshed with the driving gear 61. wherein, driving gears 9 are provided at both ends of the rotating shaft 8, and the two driving gears 9 are respectively meshed with the lifting racks 140 on the left and right sides of the outer side surface of the front side wall of the outer frame 4. Figures 1-4As shown, horizontal sliding grooves 111 are respectively provided on the opposite surfaces of the two connecting beams 11 .

[0020] like Figure 1 As shown, the left and right sides of the bottom of the mounting plate 13 are respectively provided with front wheels 2; the two front wheels 2 are connected by a wheel axle 110, and a second runner 120 is provided on the axle. Figure 2 As shown, a motor 2 7 is fixed on the mounting plate 13 , and a wheel 1 71 is provided at the power output end of the motor 2 7 ; the wheel 1 71 is connected to the wheel 2 120 on the axle 110 through a belt 130 to drive the front wheel 2 through the motor 2 7 .

[0021] like Figure 3 As shown, each connecting beam 11 is provided with a slide rail 15 extending in a direction away from the connecting beam 11 .

[0022] like Figure 4 As shown, the outer frame 4 includes three side walls in the shape of a letter "U", and also includes a carrier plate 5 at the bottom. The carrier plate 5 is rotatably fixed to the side walls of the outer frame 4 via a rotating shaft. The two side walls of the outer frame 4 include a rotating shaft 42, and the bottom of the side wall is provided with a recessed slot 41. The rotating shaft on the side wall of the outer frame 4 is inserted into the slide rail 15 of the connecting beam 11. Under the drive of the motor 6, the outer frame 4 can slide up and down relative to the slide rail 15. Figure 4 As shown, two slide bars 52 are provided on both sides of the carrier plate 5. The slide bars 52 are engaged in the slide grooves 111 of the connecting beam 11, so that when the outer frame 4 is raised, the carrier plate 5, which is connected to the bottom of the outer frame 4 via the rotating shaft, slides along the slide grooves 111. In this way, when the free end of the carrier plate is lowered, since the free end of the carrier plate is closer to the ground, the impact force on the objects when they slide to the ground is relatively small, thereby reducing the damage rate of the objects; the slide rails cooperate with the slide bar 1 to connect the outer frame to the chassis, and at the same time, cooperate with the two drive gears and the two lifting racks to increase the stability of the outer frame when it is raised; when the outer frame is not raised, the slide bar 2 is engaged in the slot, so that the carrier plate remains level, and the slide bar 2 also provides support for the outer frame.

[0023] When the free end of the carrier plate 5 is lowered, a gap will appear between the left and right sides of the carrier plate 5 and the two side walls of the outer frame 4. Objects may fall out from both sides of the carrier plate 5 through the gap, causing the landing points of the objects to be non-centralized, increasing the workload of the staff in picking up the objects. Therefore, the baffle 51 can be set to prevent the objects from falling from the gaps on both sides of the carrier plate 5, reducing the workload of the staff.

[0024] According to the present invention, an article is placed on the carrier plate 5, and the motor 2 7 is started. The motor 2 7 drives the rotating wheel 1 71 to rotate, and the rotating wheel 1 71 drives the rotating wheel 2 120 to rotate through the belt 130. The rotating wheel 2 120 drives the wheel axle 110 to rotate, and the wheel axle 110 drives the two front wheels 2 to rotate. The front wheels 2 drive the chassis 1 to move forward, and the two rear wheels 3 rotate accordingly. When arriving at the designated unloading point, the motor 6 is started, and the motor 6 drives the driving gear 61 to rotate, and the driving gear 61 drives the driven gear 100 to rotate, and the driven gear 100 drives the rotating shaft 8 to rotate, and the two driving gears 9 rotate accordingly, and the driving gear 9 drives the lifting rack 140 to move upward, and the lifting rack 140 drives the outer frame 4 to move upward, and the outer frame 4 drives the slide bar 1 42 to move upward relative to the slide rail 15. During the upward movement of the outer frame 4, the carrier plate 5 rotates and tilts, and the slide bar 2 52 leaves the slot 41, and the slide bar 2 52 slides in the slide groove 111 at the same time, so that the items can slide from the carrier plate 5 to the ground. Since the free end of the carrier plate 5 is close to the ground, the impact force received when the items slide to the ground is small, thereby reducing the damage rate of the items.

[0025] like Figure 4 As shown, baffles 51 are respectively provided on the left and right sides of the upper surface of the carrier plate 5 .
