Description

TECHNICAL FIELD

[0001] The application relates to the technical field of shelves, in particular to a shelf for AGV with power transmission. BACKGROUND

[0002] In recent years, the printed circuit board industry has been undergoing digital transformation and automation upgrade, and the automatic production mode of "mechanical hand + AGV" has gradually prevailed. This mode not only can prevent the problem of human error in product transfer, but also can solve the problem of substandard production efficiency caused by the fluctuation of human state.

[0003] However, after using AGV for transportation, the temporary storage carrier of the printed circuit board is changed from the traditional L-shaped vehicle to "pallet + shelf", the pallet is placed on the AGV, and the shelf is placed on the ground. The AGV places the pallet and the printed circuit board on the pallet on the shelf for temporary storage. The size of the pallet and the space at the bottom of the shelf are slightly larger than the size of the AGV, so that the AGV body can enter the bottom of the shelf and place the pallet in the middle to place the product. This mode leads to a larger floor space of the shelf than the traditional L-shaped vehicle, and the space in the existing automatic or semi-automatic factory is very compact, so it is difficult to place the shelf with a large floor space.

[0004] Therefore, it is necessary to provide a shelf for AGV with power transmission to reduce the floor space of the shelf, which is an important technical problem to be solved. CONTENT OF THE INVENTION

[0023] Reference Figure 1As shown, the application provides a power transmission AGV shelf, comprising: a shelf 1; two pairs of branch support plates, two pairs of branch support plates are arranged on the transverse sides of the shelf 1, one pair of branch support plates comprises a first branch support plate 2 and a second branch support plate 3, the first branch support plate 2 and the second branch support plate 3 are installed on the shelf 1; a conveyor belt 4, the conveyor belt 4 is rotatably arranged between the first branch support plate 2 and the second branch support plate 3; a driving assembly, the driving assembly is used to drive the conveyor belt 4 to make rotary motion.

[0024] Among them, the shelf 1 is the structural basis of the power transmission AGV shelf, and other structures on the power transmission AGV shelf are directly or indirectly connected with the shelf 1, and the shelf 1 also has a supporting function, which can effectively support goods. The first branch support plate 2 and the second branch support plate 3 constitute a branch support plate, the branch support plate is fixed to the shelf 1, and the branch support plate is the structural basis of the conveyor belt 4, the driving assembly and other components. The conveyor belt 4 and the driving assembly are core components of the power transmission AGV shelf, and the conveyor belt 4 and the driving assembly are arranged in the two pairs of branch support plates. The driving assembly drives the conveyor belt 4 to make rotary motion, and the tray is placed on the conveyor belt 4, so that the tray with printed circuit boards is moved to the shelf 1.

[0025] Specifically, in the temporary storage process of the printed circuit board, the printed circuit board is loaded by the tray, and then the tray is transported to the shelf 1 by the AGV. The AGV lifts the tray, so that the bottom end of the tray is flush with the upper end surface of the conveyor belt 4. At this time, the AGV moves, drives the bottom end of the tray to contact the conveyor belt 4, and the driving assembly starts to drive the conveyor belt 4 to make rotary motion, so that the tray is completely moved to the shelf 1. By arranging the conveyor belt 4 and the transmission assembly, the AGV can be completely moved to the shelf 1, so that the shelf 1 can be designed to be smaller and more compact, which is beneficial to the compact layout of the automatic or semi-automatic workshop. And the AGV does not enter the shelf 1, which is also beneficial to reduce the probability of production accidents such as AGV colliding with the shelf 1.

[0026] In detail, in this embodiment, the AGV holds the pallet in the center. During the process of moving the pallet to shelf 1, the AGV can partially enter shelf 1 to transfer the pallet's center of gravity to the conveyor belt 4. Then, the AGV can directly release its grip on the pallet, and the pallet can be completely moved onto shelf 1 via the conveyor belt 4. Alternatively, the AGV can also provide support for the pallet while the conveyor belt 4 is moving it. That is, after the AGV brings the pallet into contact with the conveyor belt 4, the AGV does not leave but releases its grip on the pallet, only providing support. In this case, the distance between the structure supporting the pallet and the conveyor belt 4 must be less than 1 / 4 of the pallet's length to ensure that the pallet does not fall during the movement. In this state, the AGV can complete the pallet transfer without entering shelf 1 at all or with only a very small portion entering shelf 1. Of course, in both of the above cases, it is not necessary for the AGV to completely enter shelf 1. Since the length of the AGV is greater than the length of the pallet, not having the AGV completely enter shelf 1 is beneficial to the structural design of shelf 1, reduces the space ratio of shelf 1, and is conducive to the compact layout of automated or semi-automated workshops.

[0027] The shelving unit 1 is constructed from cold-rolled steel plates and bars, welded together. Furthermore, the surface of shelving unit 1 undergoes powder coating treatment, giving it strong stability and corrosion resistance. It also possesses excellent mechanical properties, enabling the shelving unit for powered AGVs to adapt to diverse and harsh environmental conditions.

[0028] See Figure 1 and Figure 2 As shown, in some embodiments, the drive assembly includes: a drive roller 15, rotatably disposed between the first sub-support plate 2 and the second sub-support plate 3, the drive roller 15 partially contacting the conveyor belt 4, and the drive roller 15 driving the conveyor belt 4 to rotate; a driven roller 13, rotatably disposed between the first sub-support plate 2 and the second sub-support plate 3, the driven roller 13 partially contacting the conveyor belt 4, the driven roller 13 and the drive roller 15 forming a support structure for maintaining the shape of the conveyor belt 4; and a rotary power source 7, connected to the drive roller 15. The rotary power source 7 is a power source capable of outputting rotational force, and can be any type of motor or electric motor. The rotary power source 7 is connected to the shelf 1 via a connecting plate 8, and the output shaft of the rotary power source 7 is connected to the drive roller 15 to drive the drive roller 15 to rotate, thereby driving the conveyor belt 4 to rotate.

[0029] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes a support member 14, which connects the first sub-support plate 2 and the second sub-support plate 3, and the support member 14 partially contacts the conveyor belt 4. The support member 14 is used to support the conveyor belt 4 so that the conveyor belt 4 will not deform under the weight of the pallet.

[0030] In the embodiment, the support 14 is substantially u-shaped, two ends of the support 14 are connected with the first and second sub-support plates 2 and 3 respectively, the support 14 connects the first and second sub-support plates 2 and 3 through the first fastener 12, the first fastener 12 is preferably a screw, and the top end of the support 14 contacts the conveying belt 4 and is smooth to reduce the resistance to the conveying belt 4.

[0031] Referring to Figure 1 In some embodiments, the buffer 5 is installed on the shelf 1 and located at the ends of the first and second sub-support plates 2 and 3. The buffer 5 can be a sponge, rubber or other energy-absorbing material. After the conveying belt 4 with the tray moves completely onto the shelf 1, the tray has inertia and directly hits the shelf 1 without the buffer 5, which affects the service life of the tray and can cause the printed circuit board on the tray to fall off. The buffer 5 is installed on the shelf 1 through the second fastener 6, and the second fastener 6 is preferably a screw.

[0032] Referring to Figure 4 In some embodiments, the plurality of protrusions 9 are arranged at intervals on the outer circumferential surface of the conveying belt 4. The protrusions 9 are used to increase the friction between the conveying belt 4 and the tray, thereby improving the efficiency of the conveying belt 4 in moving the tray, and preliminarily reducing the speed of the tray when the tray completely enters the shelf 1 and is about to hit the buffer 5, so that the printed circuit board on the tray is less likely to fall off when the tray hits the buffer 5.

[0033] Referring to Figure 3 and Figure 4 In some embodiments, the plurality of mounting feet 11 are arranged on the shelf 1, and the mounting feet 11 are used to increase the contact area between the shelf 1 and the ground, so that the shelf 1 can be stably placed on the ground. The electric control box 10 is arranged on the shelf 1. The electric control box 10 is used to control the rotary power source 7, and can receive external instruction signals to start the rotary power source 7 to realize automatic temporary storage. The electric control box 10 is also provided with a control switch to facilitate manual control of the temporary storage process.

[0034] The above description is only some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
