[0031] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0032] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0034] In automated warehousing and assembly lines, the precise positioning of material boxes as the basic unit for material storage and transportation is crucial to improving production efficiency and ensuring the accuracy of material management. Traditional methods of positioning material boxes often rely on simple mechanical structures, such as positioning pins and positioning holes, but these methods are easily affected by external interference such as vibration and impact, resulting in the displacement of the material box position, which in turn affects the normal operation of automated equipment. Based on this, an embodiment of the present invention discloses a material box positioning device that can solve the technical problems of insufficient accuracy and poor positioning in the prior art, thereby simplifying the positioning process and improving the operating efficiency and accuracy of automated warehousing and assembly lines.

[0035] The technical solution of the present application is described in detail below through specific embodiments:

[0036] See also Figure 1 , Figure 2 and Figure 3 The present application provides a material box positioning device for positioning a material box 400, which includes a support frame 100, a first positioning structure 200 and a second positioning structure 300. The first positioning structure 200 is installed on the top of the support frame 100. The second positioning structure 300 is installed on the bottom of the material box 400. A conical positioning groove 310 is provided on one of the first positioning structure 200 and the second positioning structure 300, and a conical protrusion 210 is provided at the end of the other, and the conical angle of the conical protrusion 210 is less than or equal to the conical angle of the conical positioning groove 310.

[0037] The conical surface of the conical protrusion 210 and the groove wall of the conical positioning groove 310 are both heat-treated to improve durability and positioning accuracy. Specifically, the conical surface of the conical protrusion 210 and the groove wall of the conical positioning groove 310 can be treated by a quenching process. In addition, the conical positioning structure can also have a certain elasticity, can absorb vibration and impact, and improve the stability of positioning.

[0038] See also Figure 4 , Figure 5 Figure 6 and Figure 7In one embodiment, a first positioning surface 220 is provided at the top of the conical protrusion 210, and a second positioning surface 320 for cooperating with the first positioning surface 220 is provided at the bottom of the conical positioning groove 310, and the shape of the second positioning surface 320 is adapted to the shape of the first positioning surface 220.

[0039] The conical positioning structure and its matching first positioning surface 220 and second positioning surface 320 realize automatic calibration and precise positioning of the material box 400, thereby improving the positioning accuracy. The close matching of the first positioning surface 220 and the second positioning surface 320 also enhances the stability of positioning, so that the material box 400 can still maintain a stable position under external interference such as vibration and impact.

[0040] In one embodiment, the first positioning surface 220 is arc-shaped, and the first positioning surface 220 protrudes outwardly toward the conical protrusion 210 , and the second positioning surface 320 protrudes toward the bottom of the conical positioning groove 310 .

[0041] This arc-shaped design not only increases the contact area and improves the stability of positioning, but also better adapts to slight deviations of the material box 400 during the placement process, thereby achieving more precise positioning.

[0042] Of course, designing the first positioning surface 220 and the second positioning surface 320 as an arc is only one implementation method in this embodiment. In other implementation methods, it is also possible to set the first positioning surface 220 and the second positioning surface 320 as planes. However, when designing the first positioning surface 220 and the second positioning surface 320 as an arc, it is necessary to make the areas of the first positioning surface 220 and the second positioning surface 320 equal for better results.

[0043] In one embodiment, in order to ensure better matching effect and positioning stability, the area of ​​the second positioning surface 320 is greater than or equal to the area of ​​the first positioning surface 220 .

[0044] In this way, when the initial position of the material box 400 is offset, the material box 400 can move to the designated position faster during the process of moving to the designated position through the inclined surface, and the contact of the arc surface can reduce the impact force between the first positioning structure 200 and the second positioning structure 300 when the material box 400 moves to the designated position, thereby extending the service life of the first positioning structure 200 and the second positioning structure 300.

[0045] See also Figure 2 and Figure 3 In one embodiment, the top of the first positioning structure 200 is provided with a conical protrusion 210, and the bottom of the second positioning structure 300 is provided with a conical positioning groove 310. At this time, the conical protrusion 210 is at the bottom, and the conical positioning groove 310 is at the top, which is more convenient for positioning.

[0046] Of course, in other embodiments, it is also possible to dispose the conical protrusion 210 on the second positioning structure 300 and dispose the conical positioning groove 310 on the first positioning structure 200 .

[0047] See also Figure 6 In one embodiment, the diameter of the tapered positioning groove 310 is larger than the diameter of the first positioning structure 200. The design of the tapered positioning groove 310 with a larger diameter enables the tapered protrusion 210 on the first positioning structure 200 to be inserted into the tapered positioning groove 310 more easily and smoothly. This reduces the difficulty of installation and reduces the positioning error caused by improper installation.

[0048] During the insertion process, the gap between the conical protrusion 210 and the conical positioning groove 310 is gradually reduced until a tight fit is achieved. This process helps to automatically calibrate the position of the material box 400 to ensure precise positioning.

[0049] When the conical protrusion 210 is fully inserted into the conical positioning groove 310, due to the self-locking characteristics of the cone, a stable matching relationship will be formed between the two, and it is not easy to loosen due to external vibration or impact. The close matching of the arc-shaped first positioning surface 220 and the second positioning surface 320 further enhances the stability of the positioning and ensures the stable position of the material box 400 in a complex working environment.

[0050] In one embodiment, the height of the first positioning structure 200 is greater than the height of the tapered positioning groove 310. This ensures that the first positioning surface 220 on the tapered protrusion 210 and the second positioning surface 320 on the tapered positioning groove 310 form a stable fit.

[0051] When the height of the first positioning structure 200 (conical protrusion 210) is greater than the height of the conical positioning groove 310, the top of the conical protrusion 210 will protrude outside the groove after being fully inserted into the conical positioning groove 310. This design increases the contact area and friction between the positioning structures, thereby enhancing the stability of the magazine 400 during the positioning process.

[0052] See also Figure 1 and Figure 2 In one embodiment, a plurality of first positioning structures 200 are disposed on the support frame 100, and the plurality of positioning structures are arranged in two rows on the support frame 100, and each row includes at least two first positioning structures 200. A plurality of second positioning structures 300 are disposed at the bottom of the material box 400, and the number of the second positioning structures 300 is consistent with the number of the first positioning structures 200, and the second positioning structures 300 are disposed in a one-to-one correspondence with the first positioning structures 200.

[0053] The one-to-one correspondence between the multiple first positioning structures 200 and the second positioning structures 300 enables the material box 400 to be supported and positioned at multiple points when placed, thereby greatly improving the accuracy and stability of positioning. The arrangement of the two rows of positioning structures enables the material box 400 to be well constrained in the horizontal direction, preventing the material box 400 from shaking or shifting during placement.

[0054] Even if some of the first positioning structures 200 or the second positioning structures 300 cannot be fully matched due to wear, damage or position deviation, the other positioning structures can still play a role to ensure the stable positioning of the material box 400. This design also enables the positioning device to adapt to material boxes 400 of different sizes, shapes and weights, thereby improving the versatility and flexibility of the device.

[0055] In one embodiment, as the basis of the entire positioning device, the support frame 100 has sufficient rigidity and stability to support the material box 400 and the material contained therein. The shape and size of the support frame 100 can be customized according to actual application requirements. For example, two support plates 110 located in the same plane can be set on the support frame 100, and the two support plates 110 are arranged at intervals, and the two rows of first positioning structures 200 are respectively located on the two support plates 110.

[0056] The two support plates 110 are spaced apart, and each support plate 110 is provided with a first positioning structure 200, and such a layout enhances the structural stability of the entire support frame 100. The spacing between the support plates 110 can provide additional support force to prevent structural deformation or damage caused by excessive force on a single point.

[0057] Of course, making the two support plates 110 located in the same plane is only one implementation in this embodiment, which is only for making the tops of the first positioning structures 200 located in the same plane. In other implementations, the two support plates 110 are of different heights, but it is also possible to ensure that the tops of the first positioning structures 200 are located in the same plane.

[0058] In one embodiment, two first positioning structures 200 are respectively disposed on each support plate 110 , and the first positioning structures 200 on the two support plates 110 are disposed opposite to each other.

[0059] Since two first positioning structures 200 are disposed on each support plate 110 and these positioning structures are disposed opposite to each other on the support plate 110, they together provide four supporting points for the material box 400. This multi-point support design greatly enhances the stability of the material box 400 when placed, and prevents the material box 400 from shaking or tilting.

[0060] The four first positioning structures 200 are matched with the four second positioning structures 300 at the bottom of the material box 400 in a one-to-one correspondence, so that the material box 400 can be more accurately positioned at a predetermined position when placed. This high-precision positioning helps to reduce assembly errors and improve production efficiency and product quality.

[0061] Of course, setting the number of the first positioning structure 200 and the second positioning structure 300 as four is only one implementation in the present embodiment. In other implementations, setting the number of the first positioning structure 200 and the second positioning structure 300 as more may also be possible.

[0062] The first positioning structures 200 arranged opposite to each other make more efficient use of the space between the support plates 110. The material boxes 400 can be closely arranged on the support plates 110, thereby improving storage density and space utilization. This is more suitable for occasions such as automated warehousing and assembly lines that require efficient use of space.

[0063] In other embodiments, when the number of the first positioning structures 200 is large, the first positioning structures 200 on the two support plates 110 may be staggered, which can further improve the stability of the material box 400 .

[0064] Through the above embodiments, the present application has the following beneficial effects or advantages: the technical solution of the present application includes a first positioning structure 200 and a second positioning structure 300, wherein the first positioning structure 200 is installed on the support frame 100, and is used to support and position the material box 400; the second positioning structure 300 is installed at the bottom of the material box 400, and cooperates with the first positioning structure 200 to achieve accurate positioning of the material box 400. The first positioning structure 200 and the second positioning structure 300 are both designed as conical structures. This design enables the material box 400 to achieve self-calibration by its own weight when placed, thereby compensating for the technical problem of the positioning accuracy error of the existing trolley. In addition, the contact surface of the first positioning structure 200 and the second positioning structure 300 is heat-treated to improve durability and positioning accuracy. By arranging the support plate 110 and the first positioning structure 200, the overall structure can be made more compact, so as to fit the occasions such as automated warehousing and assembly lines that require efficient use of space.
