Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing equipment, in particular to an electric blocker for a double-speed chain. Background Art

[0002] The production line composed of double-speed chain assembly lines is usually called a gravity conveying system. Double-speed chain conveyors are mainly used for material transportation in assembly and processing production lines. The conveying principle is to use the speed-increasing function of the double-speed chain to make the tooling plates supporting the goods on it run quickly, stop at the corresponding operating position through the blocker, or complete the accumulation and release actions and the functions of movement, transfer, and line change through corresponding instructions.

[0003] At present, pneumatic single hook structure is commonly used in logistics of automobile factories. The stability is difficult to reach 100%, and the long-term air supply consumes a lot of energy. The use of cylinder has a lower life span than the motor for long-term operation, which increases maintenance costs and reduces reliability.

[0004] Patent publication number CN211495941U discloses a workpiece blocker, which is used to reduce or avoid noise or damage to the blocker caused by the collision between the workpiece and the blocker, and realizes intermittent blocking and release of the workpiece through the linkage between the front and rear blocking heads. However, the workpiece blocker uses a telescopic cylinder to alternately switch the blocking head between two states, thereby realizing intermittent blocking and release of the workpiece, and has relatively low stability and reliability, and low maintenance costs. Utility Model Content

[0005] The purpose of the utility model is to provide a double-speed chain electric blocker in order to overcome the defects of the above-mentioned prior art and improve the stability and reliability of the equipment.

[0019] Furthermore, the movable frame is rectangular, and the swing arm is connected to a side of the movable frame that is perpendicular to the guide rail and moves along the side.

[0020] Furthermore, two adjacent sides of the moving frame are obliquely connected with a connecting frame that enables the swing arm to move from one side of the moving frame to an adjacent side.

[0021] Furthermore, a slide rail is provided on the movable frame, and a slider is connected between the swing rod and the slide rail.

[0022] Further, the first blocking head is L-shaped, including a first long side and a first short side;

[0036] (1) The electric blocker provided by the utility model is specially designed for the double-speed chain storage area of ​​automobile manufacturing plants, aiming to efficiently and stably handle the accumulation and release process of materials, especially in an environment with a fast production rhythm (high beat). Double-speed chain technology itself is a continuous conveying system widely used in automated production lines.

[0037] (2) The electric blocker provided by the utility model has an intelligent material release control system, which can monitor the release signal issued by the production line in real time, indicating that the material has reached the specified position or completed a specific step. After receiving the release signal, the motor inside the electric blocker starts immediately, and drives the first blocker head at the front end to perform the opening action through the transmission mechanism. This design ensures that the material can be accurately separated from the first blocker head and enter the next step of the process.

[0038] (3) When the first blocking head of the electric blocker provided by the utility model opens, the second blocking head simultaneously descends and is positioned, forming a continuous blocking structure, which effectively prevents the materials following behind from moving prematurely due to inertia or other reasons, thereby ensuring the orderly spacing between materials and the stability of the production line.

[0039] (4) When the front-end material completely leaves the control area of ​​the first blocking head, the system automatically triggers the switching between the first blocking head and the second blocking head, that is, the second blocking head rises to block the subsequent material, while the first blocking head is ready to receive the material in the next cycle. This design ensures the continuous and smooth flow of materials on the double-speed chain.

[0040] (5) The design of the electric blocker provided by the utility model emphasizes simple structure and reduces unnecessary complex components, which not only reduces manufacturing costs but also facilitates maintenance and operation.

[0041] (6) The electric blocker provided by the utility model is connected to the swing rod through a motor to perform circular motion, and the mobile frame is driven to move back and forth along the guide rail by the connection between the mobile frame and the guide rail, and then the swing rod is made to slide on the slide rail on the mobile frame through the slider, thereby eliminating the force of the swing rod being perpendicular to the guide rail. The reliability and stability of the electric blocker are improved through the optimized motor drive scheme and linkage mechanism, and the energy consumption is effectively controlled, which meets the requirements of modern industry for energy conservation and emission reduction.

[0042] (7) The electric blocker provided by the utility model successfully solves the problem of operational stability of the speed chain warehouse area under the high-speed production rhythm of automobile factories through intelligent control logic, efficient material handling methods, and optimization of the overall system performance, thereby improving production efficiency and automation level, and is an important technological innovation in the automated assembly line.

[0068] And a second blocking head 64 connected to the second connecting rod 62 and the second fixing plate 68 .

[0069] In this embodiment, the moving frame 5 is rectangular, and the swing rod 3 is connected to a side of the moving frame 5 that is perpendicular to the guide rail 4 and moves along the side.

[0070] In this embodiment, two adjacent sides of the moving frame 5 are obliquely connected with a connecting frame 51 for enabling the swing rod 3 to move from one side of the moving frame 5 to an adjacent side.

[0071] In this embodiment, a slide rail 52 is provided on the movable frame 5 , and a slider 53 is connected between the swing rod 3 and the slide rail 52 .

[0072] In this embodiment, the first blocking head 63 is L-shaped, including a first long side 631 and a first short side 632;

[0073] The second blocking head 64 is L-shaped and includes a second long side 641 and a second short side 642;

[0074] One end of the first long side 631 away from the first short side 632 is rotatably connected to the bottom of the first fixing plate 67, and the middle portion of the first long side 631 is rotatably connected to the first connecting rod 61;

[0075] One end of the second long side 641 away from the second short side 642 is rotatably connected to the bottom of the second fixing plate 68 , and the middle portion of the second long side 641 is rotatably connected to the second connecting rod 62 .

[0076] In this embodiment, when the moving frame 5 moves forward to the front end of the guide rail 4, the first connecting rod 61 is perpendicular to the first long side 631, the first short side 632 blocks the material, and the first blocking head 63 is in a blocking state;

[0077] The second connecting rod 62 intersects with the second long side 641 but is not perpendicular to it, the second short side 642 rises to make the material detach, and the second blocking head 64 is in a release state;

[0078] In this embodiment, when the mobile frame 5 moves forward to the rearmost end of the guide rail 4, the first connecting rod 61 intersects with the first long side 631 but is not perpendicular to it, the first short side 632 rises to separate the material, and the first blocking head 63 is in a release state;

[0079] The second connecting rod 62 is perpendicular to the second long side 641 , the second short side 642 blocks materials, and the second blocking head 64 is in a blocking state.

[0080] In this embodiment, the mounting bracket 1 includes a plurality of mounting columns 11 distributed in a rectangular shape, and a mounting plate 12 connected to the bottom ends of the mounting columns 11 , and the mounting plate 12 is perpendicular to the guide rail 4 .

[0081] The working principle and process of the electric blocker of this embodiment are as follows:

[0082] When the mobile frame 5 is located at the front end of the guide rail 4, the first blocking head 63 is in a blocking state, and the second blocking head 64 is in a releasing state. The material is blocked by the first blocking head 63 and is in a waiting state. When receiving a release signal, the motor 2 starts, driving the swing rod 3 to make a circular motion along the slide rail 52 on the mobile frame 5 and the connecting frame 51. Since the connecting frame 51 is connected to the guide rail 4, under the limiting effect of the guide rail 4, the mobile frame 5 moves back and forth along the guide rail 4. When the mobile frame 5 moves backward, it drives the first connecting rod 61 to move backward. The first blocking head 63 is L-shaped, and its first long side 631 is connected to the first connecting rod 61 and the first fixed plate 67. Therefore, the first long side 631 moves up and intersects with the first connecting rod 61 but is not perpendicular. When the first blocking head 63 is opened, the second blocking head 64 is synchronously lowered and positioned to form a continuous blocking structure, which effectively prevents the materials following behind from moving in advance due to inertia or other reasons, and ensures the orderly spacing between materials and the stability of the production line. When the front-end material completely leaves the control area of ​​the first blocking head 63, the system automatically triggers the switching of the front and rear hooks again, that is, the second blocking head 64 rises to block the subsequent material, and the first blocking head 63 is ready to receive the material in the next cycle. This design ensures the continuous and smooth flow of materials on the double-speed chain. The first buffer block 65 and the second buffer block 66 on the first blocking head 63 and the second blocking head 64 play a buffering role when blocking the material, preventing the material from being damaged by the force of the first blocking head 63 and the second blocking head 64. The design of the electric blocker emphasizes simple structure and reduces unnecessary complex components, which not only reduces manufacturing costs, but also facilitates maintenance and operation. At the same time, through the optimized motor drive scheme and linkage mechanism, energy consumption is effectively controlled, which meets the requirements of modern industry for energy conservation and emission reduction.

[0141] The working principle and process of the electric blocker of this embodiment are as follows:

[0142] Through the first sensor, the second sensor and the controller, the electric blocker can monitor the release signal issued on the production line in real time, indicating that the material has reached the specified position or completed a specific step. When the mobile frame 5 is located at the front end of the guide rail 4, the first blocking head 73 is in a blocking state, the second blocking head 74 is in a releasing state, and the material is blocked by the first blocking head 73 and is in a waiting state. After receiving the release signal, the motor 2 is started, driving the swing rod 3 to make a circular motion along the slide rail 52 on the mobile frame 5 and the connecting frame 51. Since the connecting frame 51 is connected to the guide rail 4, under the limiting effect of the guide rail 4, the mobile frame 5 moves back and forth along the guide rail 4.

Therefore, the first long side 731 moves up and intersects with the first connecting rod 71 but is not perpendicular. When the first blocking head 73 is opened, the second blocking head 74 is synchronously lowered and positioned to form a continuous blocking structure, which effectively prevents the materials following behind from moving ahead due to inertia or other reasons, and ensures the orderly spacing between materials and the stability of the production line. When the front material is completely out of the control area of ​​the first blocking head 73, the system automatically triggers the switching of the front and rear hooks again, that is, the second blocking head 74 rises to block the subsequent materials, and the first blocking head 73 is ready to meet the materials in the next cycle. Such a design ensures the continuous and smooth flow of materials on the double-speed chain. The first buffer block 75 and the second buffer block 76 on the first blocking head 73 and the second blocking head 74 play a buffering role when blocking the materials, preventing the materials from being damaged by the force of the first blocking head 73 and the second blocking head 74. The design of the electric blocker emphasizes simple structure and reduces unnecessary complex components, which not only reduces manufacturing costs, but also facilitates maintenance and operation. At the same time, through the optimized motor drive scheme and linkage mechanism, energy consumption is effectively controlled, which meets the requirements of modern industry for energy conservation and emission reduction.
