Description

Technical Field

[0001] This utility model relates to a positioning mechanism, and more particularly to a four-way synchronous retraction positioning mechanism. Background Technology

[0002] In the field of material handling and positioning technology, material drop-off during the conveying process is a common problem that restricts the efficiency and accuracy of automated production. Its influencing factors are diverse, including cumulative errors in the mechanical transmission system, vibrations during equipment operation, inconsistencies in material shape and weight, and conveyor belt slippage. Traditional solutions to this problem typically rely on mechanical limit devices or photoelectric sensors for preliminary correction. While these can achieve a certain degree of correction, their adjustment range is limited, their adaptability is poor, and they struggle to meet the flexible production needs of multiple varieties and small batches, especially lacking rapid response capabilities in scenarios with frequent changes in material specifications.

[0003] Furthermore, although CCD vision-based positioning methods have improved in terms of accuracy, they still have significant limitations: they are sensitive to ambient lighting conditions and the reflective properties of material surfaces, and their recognition stability is easily affected by interference; the system response speed is constrained by the image processing flow, and usually requires the use of external actuators such as robotic arms to complete position adjustments, which not only increases equipment costs but also increases system complexity and debugging difficulty, resulting in a cumbersome overall workflow and significant response delays, making it difficult to meet the requirements of high-speed and highly flexible modern intelligent manufacturing. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a four-way synchronous contraction positioning mechanism that enables the alignment and positioning of multiple materials in a single action, saving workspace, and offering high efficiency and low cost.

[0005] The technical solution of this utility model is as follows: A four-way synchronous retraction positioning mechanism includes a lifting mechanism, a lifting bracket, and a product placement platform. The lifting mechanism is connected to the lifting bracket, which is connected to an X-axis telescopic mechanism and a Y-axis telescopic mechanism. The X-axis telescopic mechanism includes an X-axis telescopic clamping electric cylinder, a first X-axis telescopic bracket, and a second X-axis telescopic bracket. The two ends of the X-axis telescopic clamping electric cylinder are respectively connected to the first X-axis telescopic bracket and the second X-axis telescopic bracket, which are staggered. The first X-axis telescopic bracket is connected to at least two first X-axis positioning grippers, and the second X-axis telescopic bracket is connected to at least two second X-axis positioning grippers. The first and second X-axis positioning grippers are arranged opposite each other and are the same number. When the X-axis telescopic clamping electric cylinder is activated, it causes the first and second X-axis positioning grippers to move closer to or further away from each other. The Y-axis telescopic mechanism includes a Y-axis telescopic clamping electric cylinder, a first Y-axis telescopic bracket, and a second Y-axis telescopic bracket. The two ends of the Y-axis telescopic clamping electric cylinder are respectively connected to the first Y-axis telescopic bracket and the second Y-axis telescopic bracket, which are staggered. The first Y-axis telescopic bracket is connected to at least two second Y-axis positioning jaws. The first Y-axis positioning jaws and the second Y-axis positioning jaws are arranged opposite each other and are the same number. When the Y-axis telescopic clamping electric cylinder is activated, it causes the first Y-axis positioning jaws and the second Y-axis positioning jaws to move closer or further apart. The product placement platform has several product placement positions. The first Y-axis positioning gripper and the second Y-axis positioning gripper are located between the first X-axis positioning gripper and the second X-axis positioning gripper. Adjacent first Y-axis positioning grippers, second Y-axis positioning grippers, first X-axis positioning grippers, and second X-axis positioning grippers are located on the four sides of a product placement position for positioning by contacting the four sides of the product to be positioned.

[0006] In this embodiment, two lifting cylinders are responsible for the overall lifting and lowering of the mechanism, ensuring precise alignment between the positioning mechanism and the material conveying plane to avoid interference. Once the product is gripped and placed on the product placement position, the lifting cylinders drive the lifting brackets upwards, which in turn raise the X-axis and Y-axis telescopic mechanisms, causing the first Y-axis positioning gripper, second Y-axis positioning gripper, first X-axis positioning gripper, and second X-axis positioning gripper to rise to the perimeter of the product. The X-axis and Y-axis telescopic clamping cylinders then actuate, causing the cylinder grippers to move the first and second X-axis telescopic brackets towards the center, thus moving the adjacent first Y-axis positioning grippers, second Y-axis positioning grippers, first X-axis positioning grippers, and second X-axis positioning grippers toward the product on the placement position, positioning the product at the center.

[0007] As a further improvement of this utility model, the first X-axis telescopic bracket is connected to a plurality of first X-axis positioning jaws through a first X-axis positioning bracket, and the second X-axis telescopic bracket is connected to a plurality of second X-axis positioning jaws through a second X-axis positioning bracket. The first Y-axis telescopic bracket is connected to a plurality of first Y-axis positioning jaws via a first Y-axis positioning bracket, and the second Y-axis telescopic bracket is connected to a plurality of second Y-axis positioning jaws via a second Y-axis positioning bracket.

[0008] As a further improvement of this utility model, the first X-axis positioning gripper includes an X-axis positioning base and at least two vertically arranged X-axis positioning rods, wherein the X-axis positioning base and the at least two X-axis positioning rods are connected. The second X-axis positioning gripper has the same structure as the first X-axis positioning gripper. The first Y-axis positioning gripper includes a Y-axis positioning base and at least two vertically arranged Y-axis positioning rods, wherein the Y-axis positioning base and the at least two Y-axis positioning rods are connected. The second Y-axis positioning gripper has the same structure as the first Y-axis positioning gripper. The shapes of the X-axis positioning rods and Y-axis positioning rods can be replaced as needed, making them more convenient to use.

[0009] As a further improvement of this utility model, the X-axis positioning base is U-shaped, and the Y-axis positioning base is inverted L-shaped. Furthermore, the Y-axis positioning rod is located in the middle of the Y-axis positioning base. This technical solution avoids gaps, making the entire mechanism more compact.

[0010] As a further improvement of this utility model, the X-axis telescopic clamping electric cylinder is connected to the first X-axis telescopic bracket and the second X-axis telescopic bracket through two cylinder jaws, and the Y-axis telescopic clamping electric cylinder is connected to the first Y-axis telescopic bracket and the second Y-axis telescopic bracket through two cylinder jaws.

[0011] As a further improvement of this utility model, the X-axis telescopic mechanism includes an X-axis telescopic fixing frame, the X-axis telescopic clamping electric cylinder is connected to the X-axis telescopic fixing frame, and the X-axis telescopic fixing frame is connected to the lifting bracket; the first X-axis positioning bracket and the second X-axis positioning bracket are slidably connected to the X-axis telescopic fixing frame via linear rails. The Y-axis telescopic mechanism includes a Y-axis telescopic fixing frame, a Y-axis telescopic clamping electric cylinder connected to the Y-axis telescopic fixing frame, and a Y-axis telescopic fixing frame connected to a lifting bracket; the first Y-axis positioning bracket and the second Y-axis positioning bracket are slidably connected to the Y-axis telescopic fixing frame via linear rails.

[0013] As a further improvement of this utility model, the four-way synchronous shrinkage positioning mechanism includes a frame, and the product placement platform and lifting mechanism are connected to the frame.

[0014] As a further improvement of this utility model, the product placement platform includes several X-axis horizontal support rods and several Y-axis horizontal support rods, which are staggered to form several product placement positions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs a two-way telescopic mechanism combined with a lifting module to effectively achieve high-precision centering and positioning of materials. Dual electric cylinder coordinated control ensures centering accuracy while reducing system costs. The multi-station layout design allows for the simultaneous centering of multiple materials in a single operation, significantly improving work efficiency and saving equipment space. The overall structure adopts a symmetrical design, ensuring consistency and stability of movement in all directions.

The frame is equipped with a lifting cylinder 1, a lifting bracket, and a product placement platform. The lifting mechanism is connected to the lifting bracket, which is connected to an X-axis telescopic mechanism 2 and a Y-axis telescopic mechanism 3. The X-axis telescopic mechanism 2 includes an X-axis telescopic clamping electric cylinder 21, a first X-axis telescopic bracket 22, and a second X-axis telescopic bracket 23. The two ends of the X-axis telescopic clamping electric cylinder 21 are respectively connected to the first X-axis telescopic bracket 22 and the second X-axis telescopic bracket 23, which are staggered, through two cylinder grippers 24. The first X-axis telescopic bracket 22 is connected to at least two first X-axis positioning grippers 25, and the second X-axis telescopic bracket 23 is connected to at least two second X-axis positioning grippers 26. The first X-axis positioning grippers 25 and the second X-axis positioning grippers 26 are arranged opposite each other and are the same in number. When the X-axis telescopic clamping electric cylinder 21 is activated, it drives the first X-axis positioning grippers 25 and the second X-axis positioning grippers 26 to move closer or further apart.

[0025] Similarly, the Y-axis telescopic mechanism 3 includes a Y-axis telescopic clamping electric cylinder 31, a first Y-axis telescopic bracket, and a second Y-axis telescopic bracket.

The first Y-axis telescopic bracket is connected to at least two second Y-axis positioning grippers 33. In this embodiment, each of the first Y-axis telescopic bracket and the second Y-axis telescopic bracket is connected to five Y-axis positioning grippers. The first Y-axis positioning grippers 32 and the second Y-axis positioning grippers 33 are arranged opposite each other and are the same number. When the Y-axis telescopic clamping electric cylinder 31 is activated, it drives the first Y-axis positioning grippers 32 and the second Y-axis positioning grippers 33 to move closer or further apart.

[0026] The product placement platform has several product placement positions 4. The first Y-axis positioning gripper 32 and the second Y-axis positioning gripper 33 are located between the first X-axis positioning gripper 25 and the second X-axis positioning gripper 26. The adjacent first Y-axis positioning gripper 32, second Y-axis positioning gripper 33, first X-axis positioning gripper 25, and second X-axis positioning gripper 26 are located on the four sides of a product placement position 4, and are used to contact the four sides of the product 4 to be positioned for positioning.

[0027] Specifically, the first X-axis telescopic bracket 22 is connected to a plurality of first X-axis positioning jaws 25 via a first X-axis positioning bracket 221, and the second X-axis telescopic bracket 23 is connected to a plurality of second X-axis positioning jaws 26 via a second X-axis positioning bracket 222. Similarly, the first Y-axis telescopic bracket is connected to a plurality of first Y-axis positioning jaws 32 via a first Y-axis positioning bracket, and the second Y-axis telescopic bracket is connected to a plurality of second Y-axis positioning jaws 33 via a second Y-axis positioning bracket.

[0028] The first X-axis positioning gripper 25 includes an X-axis positioning base 251 and at least two vertically arranged X-axis positioning rods 252, which are connected. The second X-axis positioning gripper 26 has the same structure as the first X-axis positioning gripper 25. The first Y-axis positioning gripper 32 includes a Y-axis positioning base 321 and at least two vertically arranged Y-axis positioning rods 322, which are connected. The second Y-axis positioning gripper 33 has the same structure as the first Y-axis positioning gripper 32. The X-axis positioning base 251 is U-shaped, and the Y-axis positioning base 321 is inverted L-shaped. Each Y-axis positioning base 321 has a Y-axis positioning rod 322 located in the middle of the Y-axis positioning base 321.

[0029] The X-axis telescopic mechanism 2 includes an X-axis telescopic fixing frame, with the X-axis telescopic clamping electric cylinder 21 connected to the X-axis telescopic fixing frame, and the X-axis telescopic fixing frame connected to the lifting bracket; the first X-axis positioning bracket 221 and the second X-axis positioning bracket 222 are slidably connected to the X-axis telescopic fixing frame via linear rails 5. Similarly, the Y-axis telescopic mechanism 3 includes a Y-axis telescopic fixing frame, with the Y-axis telescopic clamping electric cylinder 31 connected to the Y-axis telescopic fixing frame, and the Y-axis telescopic fixing frame connected to the lifting bracket; the first Y-axis positioning bracket and the second Y-axis positioning bracket are slidably connected to the Y-axis telescopic fixing frame via linear rails 5.

[0030] There are two lifting cylinders 1, which are symmetrically located on both sides of the lifting bracket.

[0031] The product placement platform includes several X-axis horizontal support rods 6 and several Y-axis horizontal support rods 7, which are staggered to form several product placement positions 4.

[0032] In this embodiment, two lifting cylinders 1 are responsible for the overall lifting and lowering of the mechanism, ensuring precise alignment between the positioning mechanism and the material conveying plane to avoid interference. When product 4 is gripped and placed in its designated position, the lifting cylinders 1 drive the lifting bracket upwards, which in turn raises the X-axis telescopic mechanism 2 and the Y-axis telescopic mechanism 3, causing the first Y-axis positioning gripper 32, the second Y-axis positioning gripper 33, the first X-axis positioning gripper 25, and the second X-axis positioning gripper 26 to rise to the periphery of product 4. The X-axis telescopic clamping electric cylinder 21 and the Y-axis telescopic clamping electric cylinder 31 then actuate, causing the cylinder gripper 24 to move the first X-axis telescopic bracket 22 and the second X-axis telescopic bracket 23 towards the center. This causes the adjacent first Y-axis positioning gripper 32, second Y-axis positioning gripper 33, first X-axis positioning gripper 25, and second X-axis positioning gripper 26 towards product 4 in its designated position, thus positioning product 4 at the center. The entire positioning mechanism is simple in structure, compact in size, and provides precise positioning.
