[0025] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0026] Embodiment 1

[0027] Referring to Figures 1 - 4 As shown, the present utility model discloses a transport vehicle applicable to circuit boards of multiple sizes for transporting circuit boards, including:

[0028] A loading box 1, and a plurality of limiting holes 11 are opened at the bottom of the loading box 1;

[0029] A limiting component 2, the limiting component 2 includes a limiting block 22 and a plurality of fixed sliders 21, the plurality of fixed sliders 21 are circumferentially arranged on the side wall of the loading box 1, and the axial direction of the fixed slider 21 is consistent with the height direction of the side wall of the loading box 1; a taper is provided on the surface of the fixed slider 21, and the thickness of the fixed slider 21 at one end close to the port of the loading box 1 is less than the thickness of the fixed slider 21 at one end close to the bottom of the loading box 1; the limiting block 22 is detachably connected to the limiting hole 11; the limiting block 22 and the fixed slider 21 are used for fixing the circuit board.

[0030] It can be seen that in the present utility model, the fixation of circuit boards with different sizes is achieved through the cooperation between the limit block 22 and the limit holes 11 at the bottom of the loading box 1. During the assembly process, according to the size of the circuit board to be transported, the corresponding position is selected, the limit block 22 is matched with the limit holes 11 at the bottom according to the size of the circuit board, and then the circuit boards are stacked between the limit block 22 and the side wall of the loading box 1. Secondly, in the present utility model, fixed sliders 21 are installed on the side wall of the loading box 1, and during the loading process, the side wall of the circuit board is abutted against the fixed sliders 21 on the side wall, which can prevent the circuit board from directly contacting the side wall of the loading box 1 (the deformation of the loading box 1 during transportation will crush the internal circuit board). More importantly, the fixed slider 21 in the present utility model is provided with a taper, and the thickness of the fixed hole near the bottom end is greater than that near the port end. In this way, during the grasping process of the circuit board, as the circuit board is lifted, the distance between the circuit board and the fixed slider 21 becomes larger and larger, which can avoid the rubbing between the circuit board and the side wall of the loading box 1 and ensure the production quality of the circuit board.

[0031] Through the detachable connection between multiple limit holes 11 and the limit block 22, the present utility model realizes the loading and transportation of circuit boards with different sizes, improving the compatibility and transportation efficiency of the transport vehicle; secondly, through multiple fixed sliders 21 with a taper, the rubbing of the circuit board during the access process is avoided, improving the product quality.

[0032] Furthermore, four positioning blocks 12 are provided on the end face of one side of the port of the loading box 1, and the positioning blocks 12 are arranged at the four top corners of the loading box 1.

[0033] Specifically, during the actual transportation process, the transport vehicles are stacked on top of each other. To improve the stability of the stacked placement, positioning blocks 12 are provided at the four top corners of the top end face of the loading box 1. While restricting the position of the transport vehicle, it ensures the rapid stacking between multiple transport vehicles. Furthermore, positioning grooves 18 that cooperate with the positioning blocks 12 are provided at the bottom of the four top corners of the loading box 1. For clamping the positioning blocks 12 and incidentally hiding the positioning blocks 12 in the positioning grooves 18.

[0034] Furthermore, the shape of one of the positioning blocks 12 is different from the shapes of the other three positioning blocks 12.

[0035] Specifically, the reason why the shape of one of the positioning blocks 12 is different from the others is to make the directions of multiple stacked loading boxes 1 consistent and the positions of the internal circuit boards the same, facilitating the grasping by subsequent automated equipment.

[0036] Furthermore, a reinforcing plate 13 is provided on the outer side wall of the loading box 1, and a loading and unloading card slot 131 is formed between the reinforcing plate 13 and the loading box 1; a reinforcing rib 14 is provided at the bottom of the loading box 1.

[0037] Specifically, the rigidity and strength of the entire loading box 1 are improved by the reinforcing plate and the reinforcing rib 14. An unloading and loading slot 131 is formed between the reinforcing plate 13 and the loading box 1, which facilitates the handling and loading / unloading of the entire loading box 1.

[0038] Furthermore, the reinforcing plate 13 and the reinforcing rib 14 are integrally formed with the loading box 1.

[0039] Specifically, as a preferred embodiment of the present utility model, the transportation carrier for the entire circuit board is made by injection molding. The reinforcing plate 13 and the reinforcing rib 14 are integrally formed with the loading box 1 through an injection mold. Secondly, the material used for injection molding is polypropylene material. The formed transportation carrier has relatively high rigidity and strength, and the formed polypropylene material is relatively soft, which can reduce the abrasion with the circuit board during handling.

[0040] Furthermore, a bar code 15 is provided on the outer side wall of the loading box 1, and a two-dimensional code 16 is provided at the bottom of the loading box 1.

[0041] Specifically, the transportation carrier in the present utility model is adapted to an automatic handling device. In the actual operation process, the product models, quantities, and types in each loading box 1 are different. To complete product traceability, the work order numbers of the carrier and the product must be bound, and the carrier needs to be numbered. After the numbering is completed, the carrier is placed on the temporary storage rack. The transportation device travels to the bottom of the temporary storage rack according to the set route. The bar code 15 and the two-dimensional code 16 of the carrier are read by the barcode reader on the transportation device. After confirmation, the transportation device grabs the carrier and moves it. When the carrier is transported to the temporary storage rack and the automatic device, to meet the traceability requirements of the product and the carrier, the carrier needs to be scanned and confirmed. The bar code 15 on the side of the carrier and the two-dimensional code 16 at the bottom are verified when going up and down the temporary storage rack and the automatic device.

[0042] Furthermore, a sliding groove 19 that cooperates with the fixed slider 21 is formed on the inner side wall of the loading box 1. Specifically, in the present utility model, the fixed slider 21 and the loading box 1 are detachably connected through the sliding groove 19.

[0043] Furthermore, the subsequent transfer of the entire loading box 1 needs to be assisted by an automatic device. To facilitate the positioning of the loading box 1, a limiting groove 17 is provided on the outer side wall of the loading box 1, and the position is limited by the cooperation of the limiting groove 17 and the automatic device.
