Because it is made using electronic printing technology, it is called a "printed" circuit board and is one of the important components of the electronics industry. PCB boards are processed in different processing workshops, so PCB boards must be transported between different workshops. Since PCB boards are high-precision parts, they must be handled and transported with extreme care during the transfer process.
[0003] There are many transfer vehicles dedicated to transporting PCB boards in the prior art. However, some transfer vehicles have poor fixing measures for PCB boards when transporting PCB boards. On the other hand, there are bumps during long-distance transportation. These situations will cause the PCB boards to easily collide with the boxes storing the PCB boards during transportation, or collide with adjacent PCB boards, which will increase the damage rate of the PCB boards.
[0004] Therefore, a PCB board transfer vehicle with shock absorption is proposed. Utility Model Content

DETAILED DESCRIPTION
[0019] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 and Figure 2 , the utility model provides a technical solution:
[0021] A shock-absorbing PCB board transfer vehicle comprises a bottom plate 101, on which walking wheels 201 are arranged, and a shock-absorbing mechanism is arranged on the bottom plate 101. The shock-absorbing mechanism is connected to a storage box 301, and the storage box 301 is provided with a plurality of storage chambers 401 of different volumes, and a limiting mechanism is arranged in any storage chamber 401.
[0022] Specifically, the limiting mechanism is an elastic inflatable airbag 501 connected to a corresponding air pump. The elastic inflatable airbag 501 can fill the storage chamber 401 after being inflated. When the PCB board does not need to be transported, each elastic inflatable airbag 501 is in a deflated state, and an object can be placed in each storage chamber 401. When a batch of PCB boards need to be transported from one place to another, the PCB boards can be placed one by one in each storage chamber 401, and then the air pump is started to inflate the corresponding elastic inflatable airbag 501. After the elastic inflatable airbag 501 is inflated, the volume becomes larger, so that the PCB board is fixed in the storage chamber 401 through the squeezing force and elastic force. After being transported to the destination, the air pump is operated to deflate the elastic inflatable airbag 501, so that the PCB boards can be taken out one by one.
[0023] When the elastic inflatable airbag 501 is inflated to fix the PCB board in the storage chamber 401, the PCB board is wrapped by the inflated elastic inflatable airbag 501, and a number of protruding limit blocks 601 are arranged at intervals on the elastic inflatable airbag 501. These limit blocks 601 can further limit the displacement of the PCB board in the storage chamber 401, reduce the probability of its collision with the storage box 301, and thus reduce the breakage rate of the PCB board during transportation.
[0024] If a bumpy road is encountered during transportation, the PCB board placed in the storage chamber 401 is easily displaced when it is bumpy, thereby increasing the probability of it colliding with the storage box 301. In order to solve this problem, a shock absorbing mechanism is specially designed. The shock absorbing mechanism can absorb part of the vibration in this case, thereby reducing the displacement of the PCB board when it is vibrated, thereby reducing the probability of the PCB board colliding with other rigid objects, and finally reducing the breakage rate of the PCB board during transportation. Specifically, the shock absorbing mechanism includes a support rebound mechanism 703 and at least two shock absorbers 701 located at the bottom of the storage box 301, and the storage box 301 and the bottom plate 101 are connected through the support rebound mechanism 703; the two ends of any shock absorber 701 are respectively hinged to the storage box 301 and the bottom plate 101, and the support rebound mechanism 703 is located between the two shock absorbers 701. The shock absorber 701 is a prior art and will not be described in detail here.
[0025] Specifically, the support rebound mechanism 703 includes a support tube 702, a rebound mechanism 703, a pressure plate 704, a rotating shaft 705 and a support plate 706. The support tube 702 is vertically arranged on the base plate 101, and its bottom end is connected to the base plate 101, and its top end is rotatably connected to the rotating shaft 705; the pressure plate 704 is passed through the support tube 702 and can slide in the vertical direction, and the pressure plate 704 is located below the rotating shaft 705; the rebound mechanism 703 is arranged in the support tube 702 and is connected to the pressure plate 704; the support plate 706 is fixedly connected to the rotating shaft 705, and is located above the rotating shaft 705, and the support plate 706 is connected to the storage box 301; two cantilevers are symmetrically arranged on the rotating shaft 705, and the free ends of the two cantilevers are rotatably provided with rollers 707, and any roller 707 is located between the support plate 706 and the pressure plate 704. The cantilever on which the roller 707 is mounted can be either fixedly connected to the rotating shaft 705 or hinged to the rotating shaft 705 .
[0026] like Figure 1 and Figure 2As shown, when encountering a bumpy road, the storage box 301 will rotate relative to the central axis of the rotating shaft 705, resulting in inclination. During this process, if the shock absorber 701 on the left is compressed, the shock absorber 701 on the right is in a stretched state; or if the shock absorber 701 on the right is compressed, the shock absorber 701 on the left is in a stretched state. In either case, the support plate 706 will change from a horizontal state to an inclined state during this process. During the tilting process of the support plate 706, the corresponding roller 707 will be pressed downward, and the roller 707 will then press the pressure plate 704 downward, and the pressure plate 704 will move downward, and the downward pressure of the pressure plate 704 will act on the rebound mechanism 703, and the rebound mechanism 703 will be in a compressed state. When the transport vehicle passes through the bumpy road, due to the absence of bumps, the rebound mechanism 703 returns to its original position and pushes the pressure plate 704 upward, causing the pressure plate 704 to move upward. The upward thrust of the pressure plate 704 acts on the corresponding roller 707, and the roller 707 pushes the support plate 706 upward, eventually making the shock absorber 701 and the support rebound mechanism 703 in a balanced state. In this design, the two shock absorbers 701 mainly play the role of shock absorption and energy absorption, and the support rebound mechanism 703 plays the role of support and rebound.
[0027] In this embodiment, the rebound mechanism 703 is a spring, one end of which is connected to the pressure plate 704, and the other end of which is connected to the bottom of the support tube 702. In other implementations of this embodiment, the rebound mechanism 703 may also be other elastic members with the same function, such as an air bag.
[0028] In some implementations of this embodiment, a sponge 801 is provided on the inner wall of any storage chamber 401. The sponge 801 can make the contact between the PCB board and the storage box 301 flexible, thereby reducing the breakage rate of the PCB board caused by rigid collision. The sponge 801 can also be replaced by elastic rubber or the like.
[0029] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
