Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to a centering and alignment mechanism. Background Technology

[0002] In the field of automation, the traditional alignment mechanisms currently on the market mainly include several types such as dual-cylinder side-alignment mechanisms, synchronous belt side-alignment mechanisms, and single-cylinder clamping alignment mechanisms. Among them, the product center point position of dual-cylinder side-alignment mechanisms and synchronous belt side-alignment mechanisms will change with different product sizes. Dual-cylinder side-alignment mechanisms also have low compatibility, high changeover costs, and are cumbersome to change. Synchronous belt side-alignment mechanisms require correction of the material picking position every time they are changed in automation mode, resulting in relatively high structural costs and large space occupation. Nitrogen cylinder clamping alignment mechanisms have a short alignment cylinder stroke, are only suitable for small product types, have low product compatibility, require frequent replacement of grippers, and are cumbersome to change.

[0003] Moreover, with the development of technology, there are more and more round, square, and spherical products on the market. In the field of automation, the single alignment method cannot quickly change the alignment of the rapidly increasing round, square, and spherical products on the market, and cannot speed up the automated production of these products. This has seriously affected the efficiency and development of the machines and has great limitations. Utility Model Content

[0004] To address the shortcomings of existing alignment mechanisms, such as the product center point position changing with product size, limited compatibility, and cumbersome redesign, this invention provides a centering alignment mechanism that keeps the product center point fixed and offers better compatibility.

[0005] This utility model provides a centering alignment mechanism, including a support platform, a linear guide rail, an alignment slider, alignment grippers, a support fixture, and a driving mechanism. The linear guide rail is disposed on the upper end of the support platform, and the support fixture is installed at the center point of the linear guide rail. The alignment slider includes a first slider and a second slider mounted on the linear guide rail and located on both sides of the support fixture. The alignment grippers include a first gripper mounted on the first slider and a second gripper mounted on the second slider.

The synchronous belt is disposed at the lower end of the support platform, and the lower ends of the first slider and the second slider are respectively fixedly connected to the two sides of the synchronous belt.

[0006] As a further improvement of this utility model, the upper end of the bearing fixture is provided with a liftable cylindrical bearing seat.

[0007] As a further improvement of this utility model, the upper end of the cylindrical support is provided with a circular groove.

[0008] As a further improvement of this utility model, both the right-angled groove of the first gripper and the right-angled groove of the second gripper are provided with clearance grooves.

The micro-head is fixed on the support platform, and the adjusting top block is fixedly connected to the first slider.

[0010] As a further improvement of this utility model, the support platform includes an upper support plate, a lower support plate, and a plurality of support blocks disposed between the upper support plate and the lower support plate.

Detailed Implementation

[0019] In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationship, the orientation description may be based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0020] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] like Figures 1 to 3As shown, this utility model discloses a centering alignment mechanism, including a support platform, a linear guide rail 4, an alignment slider, alignment grippers, a support fixture 9, and a driving mechanism.

The alignment slider includes a first slider 5 and a second slider 6 installed on the linear guide rail 4 and located on both sides of the support fixture 9.

The synchronous belt 14 is disposed at the lower end of the support platform, and the lower ends of the first slider 5 and the second slider 6 are respectively fixedly connected to the two sides of the synchronous belt 14.

[0023] During alignment, the product is first placed on the upper end of the support fixture 9, and then the first slider 5 is moved by the drive cylinder 11. Since the lower ends of the first slider 5 and the second slider 6 are fixedly connected to the two sides of the synchronous belt 14 respectively, the second slider 6 will also move synchronously when the first slider 5 moves. At this time, the first gripper 7 on the first slider 5 and the second gripper 8 on the second slider 6 will clamp the product on the upper end of the support fixture 9, so that it is centered and aligned. Both the first gripper 7 and the second gripper 8 are provided with right-angled clamping grooves, so that round, square and spherical products can be centered and aligned, which is more versatile.

[0024] In this invention, the upper end of the support fixture 9 is provided with a liftable cylindrical support seat 10, which can be adjusted according to the thickness or shape of the product to ensure better support effect.

[0025] In this utility model, the cylindrical support 10 has a circular groove at its upper end, which facilitates the support of spherical products.

[0026] In this invention, the right-angled grooves of the first gripper 7 and the right-angled grooves of the second gripper 8 are provided with clearance grooves, which can avoid the corners of square products and ensure clamping stability.

[0027] In this invention, the centering and alignment mechanism further includes a fine-tuning mechanism. The fine-tuning mechanism includes a micro-head 12 and an adjusting top block 13 connected to the movable end of the micro-head 12. The micro-head 12 is fixed to the support platform, and the adjusting top block 13 is fixedly connected to the first slider 5. The position can be finely adjusted using the micro-head 12 to ensure effective centering and alignment.

[0028] In this utility model, the support platform includes an upper support plate 1, a lower support plate 3, and a plurality of support blocks 2 disposed between the upper support plate 1 and the lower support plate 3.

[0029] In this invention, the first gripper 7 is connected to the first slider 5 via a first pad, and the second gripper 8 is connected to the second slider 6 via a second pad.

[0032] The centering and alignment mechanism of this utility model not only satisfies the alignment of circular products, but also realizes the alignment of square and spherical products. It lays a good foundation for the fully automated production of circular, square, and spherical products, improves the compatibility of aligned product types, and makes the automated production of these products feasible. This enables the reduction of personnel, lower production costs, and improved work efficiency and product yield.
