[0035] In the related art, after processing, circuit boards and other boards are usually placed on a transport vehicle in an upright manner, and then moved and transported by the transport vehicle. However, existing transport vehicles often only limit the front and rear directions of the boards, but lack effective limits on both sides of the boards. Since the center of gravity of the upright boards is high, the boards are prone to tipping over, which not only affects the transportation efficiency of the boards, but also easily causes damage to the boards.

[0036] To this end, some embodiments of the present invention provide a plate transport vehicle 10, which is used for transporting plates such as circuit boards. Figures 1 to 5 The sheet metal transport vehicle 10 is shown for illustration.

[0037] Reference Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the plate transport vehicle 10 comprises: a frame 100, a limit baffle 200 and two locking devices 300, wherein the frame 100 can be composed of a skeleton, and a platform 110 for placing plates is provided at the top thereof, and the platform 110 is arranged horizontally to place plates or plate racks more stably. When in use, the plate transport vehicle 10 can be moved to one side of the automatic plate collecting and releasing machine, and the automatic plate collecting machine can place the plates on the platform 110 in an upright manner. In order to keep the plates in the platform 110, the limit baffle 200 is arranged along the edge of the platform 110, and the limit baffle 200 and the platform 110 can be integrally formed. The limit baffle 200 is arranged to form a receiving cavity suitable for placing plates, and the plates in the receiving cavity will be blocked by the inner wall of the limit baffle 200, so that the plates are kept in the platform 110, reducing the possibility of dislocation of the plates, thereby reducing the risk of plate rollover.

[0038] Reference Figure 1 and Figure 2As shown, in the embodiment of the utility model, two locking devices 300 are relatively arranged on both sides of the platform 110 along the width direction of the platform 110. When the plate is placed on the platform 110, the two locking devices 300 are respectively located on both sides of the plate. The locking device 300 is connected to the top of the limit baffle 200. Specifically, the locking device 300 can be welded to the limit baffle 200, or can be fastened to the limit baffle 200 by fasteners. Those skilled in the art can choose to set it according to actual conditions, and this embodiment does not limit this. The two locking devices 300 respectively include a limit portion 310 for abutting against the plate. The two limit portions 310 are relatively arranged. Based on this, when the plate is placed on the platform 110, the two limit portions 310 can respectively abut against the two opposite side walls of the plate, thereby clamping the plate and reducing the possibility of the plate tipping over during transportation.

[0039] In the embodiment of the utility model, the limiting part 310 can move along the width direction of the platform 110, so the spacing between the two limiting parts 310 can be dynamically adjusted according to the size of the plate, so that the locking device 300 can be adapted to fix plates of different sizes. Specifically, in the present embodiment, the limiting part 310 can be connected to a driving device, and the driving device can drive the limiting part 310 to move; the limiting part 310 can also be connected to an elastic member, and when the plate is placed in the platform 110, the limiting part 310 can be squeezed to compress the elastic member, and when the plate is withdrawn from the platform 110, the elastic member can drive the limiting part 310 to reset, and this embodiment does not limit this.

[0040] The embodiment of the utility model realizes the placement of the plate by setting a platform 110 at the top of the frame 100; the edge of the platform 110 is provided with a limit baffle 200 that can play a limiting role, so that the plate can be kept in the platform 110; locking devices 300 are respectively provided on both sides of the platform 110, and the two locking devices 300 respectively include a limiting portion 310 for abutting against the plate, and the two relatively set limiting portions 310 can cooperate to clamp the plate or the plate frame, thereby reducing the possibility of the plate tipping over during transportation, thereby improving the stability of plate transportation, not only improving the transportation efficiency of the plate, but also reducing the risk of damage to the plate; in addition, the limiting portion 310 can move along the width direction of the platform 110, so that the locking device 300 can adapt to the fixation of plates of different sizes, thereby improving the flexibility and universality of the plate transport vehicle 10.

[0041] Reference Figure 3 , Figure 4 and Figure 5As shown, in the embodiment of the utility model, the two locking devices 300 further include a housing 320, a connecting shaft 330 and a spring 340, wherein the housing 320 is fixedly connected to the limit baffle 200. Specifically, the housing 320 can be welded to the limit baffle 200, or can be fastened to the limit baffle 200 by fasteners. Those skilled in the art can choose to set it according to actual conditions, and this embodiment does not limit this. The connecting shaft 330 is arranged in the housing 320 and connected to the limit portion 310. Specifically, the connecting shaft 330 is slidably connected to the housing 320. When the limit portion 310 is squeezed by the plate, the connecting shaft 330 moves along the width direction of the platform 110 in a direction away from the plate.

[0042] Reference Figure 4 and Figure 5 As shown, in the embodiment of the utility model, the spring 340 is sleeved on the connecting shaft 330 and is respectively connected to the housing 320 and the limiting portion 310, and the spring 340 can drive the limiting portion 310 to move in a direction away from the housing 320. In this embodiment, when the limiting portion 310 is squeezed by the plate, the connecting shaft 330 moves in a direction away from the plate along the width direction of the platform 110, and the spring 340 is in a compressed state at this time; when the plate is evacuated from the platform 110, the spring 340 pushes the limiting portion 310 to return to its original position.

[0043] Reference Figure 4 and Figure 5 As shown, in the embodiment of the utility model, the end surface of the limiting portion 310 facing away from the shell 320 is a curved surface 311. It can be understood that the design of the curved surface 311 can better adapt to the slight undulations or irregular shapes on the surface of the plate. It should be noted that in actual applications, the surface of the plate may not be completely flat, and there may be some slight bumps or bends. The curved surface 311 enables the limiting portion 310 to better fit these surfaces, thereby ensuring stable contact between the locking mechanism and the plate, and thus making the locking effect more stable. In addition, the design of the curved surface 311 can reduce the friction between the limiting portion 310 and the plate, and the curved surface 311 can reduce the contact area between the two, thereby reducing friction, reducing wear, and extending the service life of the locking mechanism.

[0044] Reference Figure 3 , Figure 4 and Figure 5As shown, in the embodiment of the utility model, the side wall of the housing 320 is provided with a mounting portion 321. In this embodiment, two mounting portions 321 may be provided, and the two mounting portions 321 are respectively connected to the two opposite side walls of the housing 320. Among them, the mounting portion 321 is provided with a mounting hole 322, and the mounting hole 322 is fixedly connected to the limit baffle 200 through a fastener. In one example, the fastener is a screw, and the limit baffle 200 is provided with a screw hole connected to the mounting hole 322. Based on this, the fastener can be inserted into the mounting hole 322 and cooperate with the screw hole of the limit baffle 200 to achieve a fastening connection in a threaded connection. In another example, the fastener is a rivet, and the limit baffle 200 is provided with a rivet hole connected to the mounting hole 322. Based on this, the fastener can be inserted into the mounting hole 322 and connected to the rivet hole of the limit baffle 200 to achieve a fastening connection in a riveting manner. It should be noted that the fastener and the mounting hole 322 can be selected and set according to actual conditions, and this embodiment does not limit this.

[0045] Reference Figure 1 and Figure 2 As shown, in the embodiment of the utility model, two locking devices 300 form a locking assembly 400, wherein the locking assembly 400 is provided with two groups, and the two groups of locking assemblies 400 are arranged at intervals along the front-to-back direction, that is, four locking devices 300 are evenly arranged at the top of the limit baffle 200, wherein two groups cooperate to lock the plate. It can be understood that by increasing the number and distribution of the locking devices 300, the plate can be fixed and stabilized more effectively. The arrangement of the two groups of locking assemblies 400 can ensure that the plate is firmly fixed in multiple directions, further reducing the risk of the plate tipping over and improving the stability of the plate transportation.

[0046] It is understood that in order to facilitate placing the plate or plate rack 20 into the platform 110, refer to Figure 1 and Figure 2 As shown, in the embodiment of the utility model, a notch 210 is formed at the front end of the limit baffle 200 for the plate to pass through, and a roller 220 is provided between the inner walls of the limit baffle 200 opposite to each other along the width direction of the platform 110. It can be understood that the provision of the roller 220 allows the plate to be fed into the platform 110 more smoothly and smoothly, greatly reducing the jamming or stagnation phenomenon that may occur during the movement of the plate. This not only saves operation time, but also reduces the difficulty of operation, thereby improving the overall work efficiency.

[0047] Reference Figure 1 and Figure 2As shown, in the embodiment of the utility model, a plurality of pulleys 500 are provided at the bottom of the frame 100, and the plurality of pulleys 500 are arranged at intervals. It can be understood that the pulleys 500 can make the plate transport vehicle 10 easily move between different locations. Through the pulleys 500, the plate transport vehicle 10 can be more easily pulled or pushed to a designated location, thereby improving the transportation efficiency of the plates. In this embodiment, three, four, six or more pulleys 500 can be provided, and this embodiment is not limited thereto.

[0048] Reference Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the plurality of pulleys 500 include at least two fixed wheels 510 and two universal wheels 520, the two fixed wheels 510 are relatively arranged at the front end of the frame 100, and the two universal wheels 520 are relatively arranged at the rear end of the frame 100. It can be understood that the two fixed wheels 510 arranged at the front end of the frame 100 can make the plate transport vehicle 10 have better stability and straight-line driving ability, and the cooperation of the two fixed wheels 510 can help the plate transport vehicle 10 to maintain a straight line during driving, reducing the possibility of deviating from the predetermined path. The two universal wheels 520 arranged at the rear end of the frame 100 can rotate in any direction, which makes the plate transport vehicle 10 more comfortable when it needs to turn, adjust the direction or move in a small space.

[0049] Reference Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the rear end of the frame 100 is protruded to form a handrail 600. It can be understood that the design of the handrail 600 enables the operator to apply force more conveniently when pushing or pulling the plate transport vehicle 10.
