Description

Technical Field

[0001] The invention belongs to the field of machinery, and relates to a posture adjustment mechanism that uses a mechanical structure and a sensor element to achieve automatic docking and intelligent posture adjustment, and is specifically an automatic horizontal alignment posture adjustment mechanism. Background Art

[0002] As an important equipment for heat treatment of parts, heat treatment furnaces are mainly divided into vertical heat treatment furnaces and horizontal heat treatment furnaces. Vertical heat treatment furnaces are equipped with a material frame lifting device that can move vertically. Workers only need to place the material frame on the material platform to easily operate the material in and out of the furnace through buttons. However, horizontal heat treatment furnaces do not have this automatic loading and unloading function, and the material placement platform of horizontal heat treatment furnaces is located near the center of the furnace cavity, making it difficult for workers to manually place the material frame.

[0003] At present, workers on site use semi-automatic material carts, and the insertion and placement of the material frame and the movement and steering of the cart are all manually controlled by workers. The position of each loading and unloading and the placement of the material frame should be within the allowable range, but the movement path and operation method of the material cart each time the material is loaded and unloaded vary from person to person, resulting in workers needing to fine-tune the position of the material cart multiple times each time they load and unload materials to ensure that the materials are placed in the specified position with the specified posture. The cumbersome loading and unloading operations of materials affect the production efficiency of the products and increase the labor intensity of workers. Summary of the invention

[0004] Purpose of the Invention

[0005] In order to solve the above problems, the present invention proposes an automatic alignment horizontal posture adjustment mechanism. The mechanism has the ability of automatic posture adjustment to ensure that the placement position and posture of the material frame meet the requirements, assist workers to quickly complete loading and unloading, and improve production efficiency.

[0006] Technical Solution

[0007] The present invention proposes an automatic alignment horizontal posture adjustment mechanism, which is used to solve the problem of difficult posture adjustment of a material frame during loading and unloading of a horizontal heat treatment furnace. The mechanism mainly comprises an automatic recognition system and a mechanical adjustment system.

[0008] The automatic identification system mainly includes two modules, one is a visual identification module, which uses a two-dimensional code positioning navigation sensor and is installed on a mobile chassis 4. The two-dimensional code is installed at a fixed relative position to the heat treatment furnace, and the two-dimensional code positioning navigation sensor can sense the relative position of the heat treatment furnace and the automatic alignment horizontal posture adjustment mechanism by scanning and identifying the position of the two-dimensional code; the second is a control module, which uses a programmable logic controller and is installed on a mobile chassis 4. Based on the relative position information identified in the visual identification module, the programmable logic controller will process and generate a control signal to control the first servo motor 5 and the second servo motor 6 in the mechanical adjustment system to provide the required power, so that the rotating platform 15 has a certain deflection angle, and the material platform 1 has a certain displacement distance.

[0009] The mechanical adjustment system comprises a main material platform 1, a mobile chassis 4 and a rotating platform 15. A circular guide rail 3 is arranged on the mobile chassis 4, and the circular guide rail 3 is connected to the rotating platform 15.

[0010] The mobile chassis 4 is also provided with a second servo motor 6 and a second screw rod 8. The first nut 13 is installed on the second screw rod 8. The first nut 13 is connected to the nut connecting block 9. The nut connecting block 9 is connected to the rotating shaft 10. The rotating shaft 10 is connected to the connecting block 11. The connecting block 11 is connected to the second linear guide 12. The second servo motor 6 provides power to drive the second screw rod 8 to rotate, thereby driving the first nut 13 to move left and right, and 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 will also move left and right accordingly. At this time, the rotating platform 15 is subjected to force and begins to rotate around the rotation center of the circular guide 3 under the action of the circular guide 3. At the same time, when the connecting block 11 moves left and right, the second linear guide 12 adjusts the distance between the connecting block 11 and the rotation center of the circular guide 3 to ensure that the rotating platform 15 can rotate around the rotation center of the circular guide 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 provided with a first servo motor 5 and a first screw rod 7. A second nut 14 is mounted on the first screw rod 7, and the second nut 14 is connected to the material platform 1. The first servo motor 5 provides power to drive the first screw rod 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. Under the action of the first linear guide rail 2, the material platform 1 will move left and right.

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

[0014] Furthermore, the material platform 1, the mobile chassis 4 and the rotating platform 15 are made of cast iron material, which not only meets the requirements of structural strength but also has good economy.

[0015] The beneficial effects of this application are:

[0016] The present invention proposes an automatic alignment horizontal posture adjustment mechanism, which has a safe and reliable structure, a reasonable design and high feasibility. The mechanism mainly includes an automatic recognition system and a mechanical adjustment system. The visual recognition module in the automatic recognition system uses a two-dimensional code positioning technology to identify and determine the relative position between the automatic alignment horizontal posture adjustment mechanism and the heat treatment furnace. According to the acquired relative position between the automatic alignment horizontal posture adjustment mechanism and the heat treatment furnace, the control module calculates and analyzes the angle and distance that the material frame needs to be adjusted, and generates a posture adjustment instruction to send to the mechanical adjustment system. The mechanical adjustment system mainly includes a servo motor and a mechanical mechanism, which are used to adjust the position and angle of the material frame to ensure that the posture and position of the material frame meet the production requirements.

[0017] The automatic alignment horizontal posture adjustment mechanism has the ability of logic processing and posture adjustment, including functions such as information acquisition, information processing, information transmission, and command execution. It can independently complete the posture adjustment operation during the loading and unloading process of the horizontal heat treatment furnace. It has a high degree of automation, can effectively liberate labor, improve parts production efficiency, meet the actual use needs on site, and provide useful help for shortening product production cycle and reducing workers' labor intensity.

[0021] In order to make the purpose, technical scheme and advantages of the implementation of the present invention clearer, the technical scheme in the embodiment of the present invention will be described in more detail in combination with the embodiment of the present invention. In the example, the same or similar reference numerals throughout represent the same or similar originals or elements with the same or similar functions. The described embodiments are part of the embodiments of the present invention, not all of them. The embodiments described below by reference are exemplary and intended to be used to explain the present invention, and should not be construed as limitations on the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present invention. The following is a detailed description in combination with the embodiments of the present invention.

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

[0023] The present invention mainly comprises an automatic recognition system and a mechanical adjustment system. The automatic recognition system is mainly used to obtain and process information. Through the two-dimensional code positioning technology, a visual sensor is used to scan the two-dimensional code installed at a fixed position to identify and calculate the relative position of the heat treatment furnace and the automatic alignment horizontal posture adjustment mechanism. According to the acquired relative position data, the angle and translation distance that the material frame needs to be adjusted 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 recognition system and adjust the position and angle of the material frame on the material platform 1. Figure 1 , 2 As shown in Figure 3, the mechanical adjustment system mainly includes a material platform 1, a mobile chassis 4, and a rotating platform 15. The mobile chassis 4 is provided with a Mecanum wheel, so that the movement mode of the automatic alignment horizontal posture adjustment mechanism is flexible and changeable. 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 screw rod 7, a second screw rod 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 attitude adjustment mechanism is working, the visual recognition module of the automatic recognition system scans the QR code installed at a fixed position through a visual camera to determine and identify the relative position information of the horizontal heat treatment furnace and the automatic alignment and horizontal attitude adjustment mechanism. The control module of the automatic recognition system will calculate the relative position of the horizontal heat treatment furnace and the automatic alignment and horizontal attitude adjustment mechanism based on the relative position information obtained by the visual recognition module, and generate a control instruction to send to the mechanical adjustment system.

[0026] After receiving the instruction, the second servo motor 6 of the mechanical adjustment system starts to work, driving the second screw 8 to rotate, and driving the first nut 13 to move linearly to the left on the second screw 8. The first nut 13 is connected to the nut connecting block 9, driving the nut connecting block 9 to move linearly to the left at the same time. The nut connecting block 9 is connected to the connecting block 11 through the rotating shaft 10. The connecting block 11 is installed on the slider of the second linear guide 12, and the second linear guide 12 is installed on the rotating platform 15. The linear movement of the nut connecting block 9 to the left will cause the slider of the second linear guide 12 to move to the left under the force. Under the action of the circular guide 3, the second linear guide 12 deflects to the left, that is, the rotating platform 15 deflects clockwise. In this process, the distance between the first nut 13 and the rotation center axis of the rotating platform 15 increases, so that the slider of the second linear guide 12 moves along the second linear guide 12.

[0027] After receiving the instruction, the mechanical adjustment system will start working the first servo motor 5, driving the first screw rod 7 to start rotating, driving the second nut 14 to move linearly to the left, the second nut 14 is connected to the material platform 1, and the material platform 1 is connected to the rotating platform 15 through the first linear guide rail 2. The second nut 14 moving linearly to the left will drive the material platform 1 to move to the left along the first linear guide rail 2, thereby driving the material frame to move to the left.

[0028] When the material frame is placed on the material platform inside the horizontal heat treatment furnace through other mechanisms, the automatic alignment horizontal posture adjustment mechanism will be reset in a movement mode opposite to the above mode.

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