Description

Technical Field

[0001] This invention belongs to the field of mechanics and relates to an attitude adjustment mechanism that uses mechanical structures and sensing elements to achieve automatic docking and intelligent attitude adjustment. Specifically, it is an automatic alignment horizontal attitude adjustment mechanism. Background Technology

[0002] Heat treatment furnaces, as crucial equipment for heat treatment of parts, are mainly divided into vertical and horizontal types. Vertical heat treatment furnaces are equipped with a vertically movable material frame lifting device, allowing workers to easily operate the loading and unloading of materials by simply placing the material frame on the material platform and pressing buttons. However, horizontal heat treatment furnaces lack this automatic loading and unloading function, and the material placement platform in horizontal furnaces is located near the center of the furnace cavity, making manual placement of the material frame difficult for workers.

[0003] Currently, the on-site workers are using semi-automated material handling carts. The insertion and placement of material frames, as well as the movement and steering of the carts, are all manually controlled by the workers. While the loading and unloading positions and the placement posture of the material frames should be within acceptable limits each time, the movement path and operation method of the material handling cart vary from person to person. This forces workers to make multiple fine adjustments to the position of the material handling cart each time to ensure that the materials are placed in the designated positions with the specified posture. This cumbersome material handling operation affects production efficiency and increases the labor intensity of the workers. Summary of the Invention

[0004] Purpose of the invention

[0005] To address the aforementioned problems, this invention proposes an automatic alignment and horizontal adjustment mechanism. This mechanism has the ability to automatically adjust its orientation, ensuring that the placement and posture of the material frame meet the requirements, assisting workers in quickly completing loading and unloading operations, and improving production efficiency.

[0006] Technical solution

[0007] This invention proposes an automatic alignment and horizontal adjustment mechanism to solve the problem of difficult material frame adjustment during the loading and unloading process of a horizontal heat treatment furnace. The mechanism mainly includes an automatic identification system and a mechanical adjustment system.

[0008] The automatic identification system mainly comprises two modules: a visual identification module, which uses a QR code positioning and navigation sensor mounted on the mobile chassis 4. The QR code is installed at a fixed relative position to the heat treatment furnace. The QR code positioning and navigation sensor can sense the relative position between the heat treatment furnace and the automatic alignment and horizontal adjustment mechanism by scanning and identifying the QR code's position. The second module is a control module, which uses a programmable logic controller (PLC) mounted on the mobile chassis 4. Based on the relative position information identified in the visual identification module, the PLC processes and generates control signals to control the first servo motor 5 and the second servo motor 6 in the mechanical adjustment system to provide the necessary power, causing the rotating platform 15 to yaw at a certain angle and the material platform 1 to generate a certain displacement distance.

[0009] The mechanical adjustment system includes a main material platform 1, a movable chassis 4, and a rotating platform 15. The movable chassis 4 is equipped with a circular guide rail 3, which is connected to the rotating platform 15.

[0010] The mobile chassis 4 is also equipped with a second servo motor 6 and a second lead screw 8. A first nut 13 is installed on the second lead screw 8. The first nut 13 is connected to a nut connecting block 9. The nut connecting block 9 is connected to a rotating shaft 10. The rotating shaft 10 is connected to a connecting block 11. The connecting block 11 is connected to the second linear guide rail 12. The second servo motor 6 provides power to drive the second lead screw 8 to rotate, thereby driving the first nut 13 to move left and right. The nut connecting block 9 moves left and right accordingly. The nut connecting block 9 is connected to the connecting block 11 through the rotating shaft 10, and the connecting block 11 also moves left and right accordingly. At this time, the rotating platform 15 is under force and begins to rotate around the rotation center of the circular guide rail 3 under the action of the circular guide rail 3. At the same time, when the connecting block 11 moves left and right, the distance between the connecting block 11 and the rotation center of the circular guide rail 3 is adjusted by the second linear guide rail 12 to ensure that the rotating platform 15 can rotate around the rotation center of the circular guide rail 3 at any angle.

[0011] The rotating platform 15 is also provided with a first linear guide rail 2, which is connected to the material platform 1.

[0012] The rotating platform 15 is also equipped with a first servo motor 5 and a first lead screw 7. A second nut 14 is installed on the first lead screw 7, and the second nut 14 is connected to the material platform 1. The first servo motor 5 provides power to drive the first lead screw 7 to rotate, thereby driving the second nut 14 to move left and right. The second nut 14 is connected to the material platform 1, and under the action of the first linear guide rail 2, the material platform 1 will undergo left and right displacement.

[0013] The mobile chassis 4 is also equipped with Mecanum wheels.

[0014] Furthermore, the material platform 1, the mobile chassis 4, and the rotating platform 15 are made of cast iron, which satisfies the structural strength requirements while also being economical.

[0015] The beneficial effects of this application are as follows:

[0016] This invention proposes an automatic alignment and horizontal adjustment mechanism, which is structurally safe and reliable, rationally designed, and highly feasible. The mechanism mainly includes an automatic identification system and a mechanical adjustment system. The visual recognition module in the automatic identification system uses QR code positioning technology to identify and determine the relative position between the automatic alignment and horizontal adjustment mechanism and the heat treatment furnace. Based on the obtained relative position, the control module calculates and analyzes the angle and distance that the material frame needs to be adjusted, and generates an adjustment command which is sent to the mechanical adjustment system. The mechanical adjustment system mainly includes a servo motor and a mechanical mechanism, used to adjust the position and angle of the material frame to ensure that the posture and position of the material frame meet production requirements.

[0017] The automatic alignment and horizontal adjustment mechanism possesses logic processing and posture adjustment capabilities, including functions such as information acquisition, information processing, information transmission, and command execution. It can autonomously complete the posture adjustment operation during the loading and unloading process of a horizontal heat treatment furnace, exhibiting a high degree of automation. This effectively frees up labor, improves parts production efficiency, meets actual on-site usage needs, and provides beneficial assistance in shortening product production cycles and reducing worker labor intensity.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be described in more detail below. In the examples, the same or similar reference numerals denote the same or similar components or elements having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this invention. The embodiments described below with reference to reference are exemplary and intended to explain this invention, and should not be construed as limiting the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. The embodiments of this invention will be described in detail below.

[0022] This invention proposes an automatic alignment and horizontal adjustment mechanism. Through reasonable structural design and precise stroke control, it effectively solves the problems of difficult loading and unloading operations and low loading and unloading efficiency of semi-automatic material carts on site. It meets the actual needs of on-site use, can improve product production efficiency, and reduce the labor intensity of workers.

[0023] This invention mainly comprises an automatic identification system and a mechanical adjustment system. The automatic identification system is primarily used to acquire and process information. Utilizing QR code positioning technology, a visual sensor scans a QR code installed at a fixed location to identify and calculate the relative position of the heat treatment furnace and the automatic alignment and horizontal adjustment mechanism. Based on the acquired relative position data, the required adjustment angle and translation distance of the material frame are calculated, and corresponding instructions are generated and sent to the mechanical adjustment system.

[0024] The mechanical adjustment system is mainly used to execute the instructions of the automatic identification system and adjust the position and angle of the material frame on the material platform 1. For example... Figure 1 , 2 As shown in Figure 3, the mechanical adjustment system mainly includes a material platform 1, a movable chassis 4, and a rotating platform 15. The movable chassis 4 is equipped with Mecanum wheels, allowing for flexible and varied movement of the automatic alignment and horizontal adjustment mechanism. The mechanical adjustment system also includes a first linear guide rail 2, a circular guide rail 3, a first servo motor 5, a second servo motor 6, a first lead screw 7, a second lead screw 8, a nut connecting block 9, a rotating shaft 10, a connecting block 11, a second linear guide rail 12, a first nut 13, and a second nut 14.

[0025] When the automatic alignment and horizontal adjustment mechanism is working, the vision recognition module of the automatic recognition system scans the QR code installed at a fixed position through a vision camera to determine the relative position information of the horizontal heat treatment furnace and the automatic alignment and horizontal adjustment mechanism. Based on the relative position information obtained by the vision recognition module, the control module of the automatic recognition system calculates the relative position of the horizontal heat treatment furnace and the automatic alignment and horizontal adjustment mechanism, generates control commands, and sends them to the mechanical adjustment system.

[0026] Upon receiving a command, the mechanical adjustment system activates the second servo motor 6, driving the second lead screw 8 to rotate. This causes the first nut 13 to move linearly to the left along the second lead screw 8. The first nut 13 is connected to the nut connecting block 9, simultaneously causing the nut connecting block 9 to move linearly to the left. The nut connecting block 9 is connected to the connecting block 11 via the rotating shaft 10. The connecting block 11 is mounted on the slider of the second linear guide rail 12, which is mounted on the rotating platform 15. The linear movement of the nut connecting block 9 to the left causes the slider of the second linear guide rail 12 to move to the left under the force of the circular guide rail 3. Under the action of the circular guide rail 3, the second linear guide rail 12 wobbles to the left, causing the rotating platform 15 to wobble clockwise. During this process, the distance between the first nut 13 and the rotation center axis of the rotating platform 15 increases, causing the slider of the second linear guide rail 12 to move along the second linear guide rail 12.

[0027] Upon receiving the command, the mechanical adjustment system will also start working, driving the first servo motor 5 to rotate. This will cause the second nut 14 to move linearly to the left. The second nut 14 is connected to the material platform 1, which is connected to the rotating platform 15 via the first linear guide rail 2. The linear movement of the second nut 14 to the left will cause the material platform 1 to move to the left along the first linear guide rail 2, thereby causing the material frame to shift to the left.

[0028] When the material waiting frame is placed on the material platform inside the horizontal heat treatment furnace by other mechanisms, the automatic alignment and horizontal adjustment mechanism will reset in the opposite manner to the above.

[0029] Other posture adjustment methods of the automatic alignment horizontal posture adjustment mechanism are similar to the above-mentioned movement methods.
