Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a central positioning mechanism. Background Art

[0002] Variable-track belt conveyors can achieve centering of different materials. Positioning is divided into X-axis positioning and Y-axis positioning. The X-axis is the direction of material conveyance, and the Y-axis is the horizontal direction perpendicular to the X-axis. Positioning in the Y-axis direction can be achieved by adjusting the distance between the belts. Positioning in the X-axis direction generally relies on manual adjustment of the positioning position or the use of adjustable motion mechanisms such as modules or electric cylinders. Manual adjustment of the positioning position requires manual operation for each positioning operation, which is labor-intensive and has high labor costs. Relying on adjustable motion mechanisms such as modules or electric cylinders for positioning requires the addition of new modules or electric cylinders, increasing production costs. In addition, the X-axis and Y-axis directions must be adjusted separately, resulting in low positioning efficiency. Utility Model Content

[0029] See Figures 1 to 5This embodiment provides a center positioning mechanism 2, comprising a bracket 21, a guide block 22, a connecting block 23, and a positioning assembly 24. The guide block 22 is movably mounted on the bracket 21 in the second direction. The connecting block 23 is mounted on the guide block 22 and is connected to the track 1 on one side in the first direction. Specifically, the connecting block 23 is connected to the track 1 on the inner side in the first direction and is movable along the track 1 in the second direction. There are two tracks 1, each extending in the first direction. Each track 1 is provided with a conveyor belt for conveying products in the first direction, so that the conveying direction is backward from the first direction. The two tracks 1 are connected by a transmission structure, which can be a screw drive with threads at both ends of the screw in opposite directions. Driven by a motor, the two tracks 1 can simultaneously move toward and away from each other to position the product in the second direction. The positioning assembly 24 comprises a fixed plate and a blocking unit 242 mounted on the fixed plate. The blocking unit 242 is used to position the product in the first direction. The first direction is perpendicular to the second direction. The first direction is also the length direction of the product, and the second direction is also the width direction of the product. The fixed plate is movably arranged on the bracket 21 along the first direction, and the guide block 22 is connected to the fixed plate in a transmission connection. When the guide block 22 drives one side track 1 to move away from the other side track 1, it can drive the fixed plate to move along the conveying direction of the product to position the product along the conveying direction. That is, when the guide block 22 moves in the second direction, it can drive the fixed plate to move in the first direction. When the guide block 22 drives one side track 1 to move toward the other side track 1, it can drive the fixed plate to move in the conveying direction away from the product to reset it.

[0030] In this embodiment, the guide block 22 can be movably provided on the bracket 21 along the second direction, and the connecting block 23 can be connected to one of the two tracks 1. When the track 1 moves along the second direction, it can drive the connecting block 23 and the guide block 22 to move along the second direction. A blocking unit 242 for positioning the product along the first direction is provided on the fixed plate. The guide block 22 is in transmission connection with the fixed plate. When the guide block 22 moves along the second direction, it can drive the fixed plate to move along the first direction, thereby driving the blocking unit 242 on the fixed plate to move backward along the first direction to position the product along the first direction. In this solution, when the track 1 moves along the second direction to position the product along the second direction, it can simultaneously drive the blocking unit 242 to move along the first direction and position the product along the first direction, resulting in high positioning efficiency. It replaces manual positioning and reduces labor costs. This solution has a simple structure and reduces production costs.

[0031] In one embodiment, Figure 3 and Figure 4As shown, the fixed plate is arranged at the bottom of the guide block 22, and a guide rail 221 is arranged on the bottom surface of the guide block 22. The guide rail 221 is arranged tilted in the horizontal direction, and the front end of the guide rail 221 along the conveying direction is close to the connecting block 23, and the rear end of the guide rail 221 along the conveying direction is away from the connecting block 23. A guide shaft 241a is provided on the fixed plate, and the guide shaft 241a is movably arranged in the guide rail 221 along the extension direction of the guide rail 221. The extension direction of the guide rail 221 does not coincide with the first direction and the second direction. The above structure can achieve that when the guide block 22 drives one side track 1 to move in the direction away from the other side track 1, it can drive the fixed plate to move along the conveying direction of the product. In addition, the above structure is simple and has high transmission efficiency. While positioning the product along the second direction, the product can also be positioned along the first direction, and the positioning efficiency is high.

[0032] In one embodiment, Figure 5 As shown, the tangent of the angle θ between the extension direction of the guide rail 221 and the first direction is equal to the ratio of the product's width to its length: tanθ = Y / X, where Y is the product's width and X is its length. This means that the extension direction of the guide rail 221 coincides with the extension direction of one of the product's diagonals. The angle θ can be calculated by calculating the tangent of the angle θ between the extension direction of the guide rail 221 and the first direction. For products with a constant aspect ratio, this arrangement allows the guide block 22 to move a distance Y1 in the second direction while the fixed block 241 moves a distance X1 in the first direction according to the product's aspect ratio, thereby achieving precise positioning of the product along the first direction.

[0033] In one embodiment, Figure 5 As shown, the tangent of the angle θ between the extension direction of the guide rail 221 and the first direction is equal to the ratio of the average width to the average length of the multiple products. When multiple products have different aspect ratios, the tangent of the angle θ between the extension direction of the guide rail 221 and the first direction is calculated by calculating the average length and average width of the multiple products, and then using the ratio of the average width to the average length to determine the tangent of the angle θ. This structure allows for coarse positioning of products with varying aspect ratios within a certain tolerance, improving positioning efficiency.

[0034] In one embodiment, Figures 3 to 5As shown, the guide rail 221 is an elongated hole, and the guide shaft 241a can pass through the guide rail 221 and out of the guide block 22. The guide rail 221 is an elongated hole that can penetrate the thickness direction of the guide block 22. The top end of the guide shaft 241a passes through the guide rail 221 in the vertical direction, so that the guide shaft 241a and the guide rail 221 are not easily separated, thereby improving the stability of the fit between the guide shaft 241a and the guide rail 221.

[0035] In one embodiment, the diameter of the guide shaft 241 a is smaller than or equal to the diameter of the guide rail 221 , which facilitates the sliding of the guide shaft 241 a within the guide rail 221 , thereby improving the efficiency of positioning the product along the first direction.

[0036] In one embodiment, Figure 3 and Figure 4 As shown, the blocking unit 242 includes a blocking driver 241b and a blocking member 241a. The blocking member 241a is disposed on a driving member of the blocking driver 241b, and the blocking driver 241b is used to drive the blocking member 241a to move in the vertical direction. The blocking driver 241b is a cylinder, and its output end is disposed in the vertical direction and can drive the blocking member 241a to move in the vertical direction.

[0037] When the product needs to be positioned along the first direction, or when the product is thick, the blocking driving member 241b drives the blocking member 241a to rise along the first direction to abut the product. This can avoid interference with other parts when the blocking unit 242 is idle, and can also be applied to products of different thicknesses.

[0038] In one embodiment, Figure 3 and Figure 4 As shown, a first slide rail 212a and a first slide groove extending along the second direction are respectively provided on opposite sides of the bracket 21 and the guide block 22, and the guide block 22 is movably provided on the bracket 21 along the second direction through the cooperation between the first slide groove and the first slide rail 212a.

[0039] The bracket 21 includes two opposing support blocks 211 and a support rod 212 connecting the two support blocks 211. A first slide rail 212a extending in the second direction is disposed on the top of the support rod 212. A first slide groove extending in the second direction is disposed on the bottom of the guide block 22. The first slide rail 212a and the first slide groove cooperate with each other. Both the first slide rail 212a and the first slide groove can be provided in multiple equal sections. This structure ensures more stable sliding of the guide block 22 on the bracket 21, thereby improving positioning accuracy and efficiency.

[0040] In one embodiment, Figure 3 and Figure 4As shown, a second slide rail 212b and a second slide groove extending along the first direction are respectively provided on opposite sides of the bracket 21 and the fixed block 241, and the fixed block 241 is movably provided on the bracket 21 along the first direction through the cooperation between the second slide groove and the second slide rail 212b.

[0041] A second slide rail 212 b is provided on the top of the support rod 212 along the first direction, and a second slide groove is provided on the bottom of the fixing block 241 along the first direction. The second slide rail 212 b matches the second slide groove.

[0042] In one embodiment, Figure 3 and Figure 4 As shown, the bracket 21 includes two support blocks 211 and a support rod 212 connected between the two support blocks 211. The support rod 212 is arranged along the second direction, and the two support blocks 211 are arranged opposite each other along the second direction. This structure has good support stability and occupies a small space, which can reduce the overall volume of this embodiment and avoid interference with other structures.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
