A steering mechanism for an assembly line

Abstract

This utility model discloses a steering mechanism for an assembly line, comprising two horizontal conveyor belts and a placement plate. A steering mechanism is provided on one side of the horizontal conveyor belts, and the placement plate can move on the horizontal conveyor belts and the steering mechanism. The steering mechanism includes a worktable, a support frame, a mounting block, and ball bearings. This solves the problem that existing production assembly lines generally use two horizontal conveyor belts and one vertical transmission belt for steering, with placement plates for placing parts installed on the conveyor belts. The placement plates are sequentially passed to the workers via the conveyor belts. However, in this method, when one end of the placement plate enters the vertical transmission belt from the horizontal conveyor belt, it will simultaneously receive the movement forces from both transmission belts, which may cause the placement plate to jam, resulting in a lack of continuity in the assembly line.

Description

Technical Field

[0001] This utility model relates to the field of assembly line technology, and in particular to a steering mechanism for an assembly line. Background Technology

[0002] An assembly line is a production line in a factory used to assemble products. If a single person were to assemble a complex product, it would take a lot of time. However, if the product is broken down into several parts and assembled by a corresponding number of people, the assembly time can be greatly shortened and the factory's production efficiency can be increased.

[0003] Existing production assembly lines typically use two horizontal conveyor belts and one vertical drive belt for steering. Placement plates for holding parts are installed on the conveyor belts, and the plates are passed to workers one by one. However, when the plate enters the vertical drive belt from the horizontal conveyor belt, it will receive the motion force from both drive belts at the same time. This may cause the plate to jam, resulting in a lack of continuity in the assembly line. Utility Model Content

[0004] This application provides a steering mechanism for an assembly line, which can solve the problem that existing production assembly lines use two horizontal conveyor belts and one vertical conveyor belt for steering. This causes the placement plate moving on the conveyor belt to be subjected to two forces simultaneously when it is transported out of the horizontal conveyor belt and into the vertical conveyor belt, resulting in the placement plate getting stuck.

[0005] This application provides a steering mechanism for an assembly line, including two horizontal conveyor belts and a placement plate. A steering mechanism is provided on one side of the horizontal conveyor belts. The placement plate can move on the horizontal conveyor belts and the steering mechanism. The steering mechanism includes a worktable, a support frame, mounting blocks, and ball bearings. The support frame is placed on the ground, and the worktable is mounted on the support frame. A slot is provided on the worktable, and several mounting blocks are installed in the slot. Ball bearings are installed on the mounting blocks.

[0006] Furthermore, several of the mounting blocks are simultaneously arranged along both the length and width directions of the slot.

[0007] Furthermore, the mounting block has a cavity, a movable mechanism is provided in the cavity, the ball is mounted on the movable mechanism, and a detachable end cap is installed on the mounting block, with one end of the ball extending out of the end cap.

[0008] Furthermore, the movable mechanism includes a movable rod, a support block, a locking block, a spring, and a limiting mechanism. A spring is installed between the support block and the mounting block. The ball bearings are placed on the support block. The limiting mechanism is located around the support block and cooperates with the support block. One end of the movable rod is rotatably connected to the support block, and the other end of the movable rod is located below the worktable. The locking block is fixedly connected to the movable rod. The mounting block and the worktable have the same movable groove.

[0009] Furthermore, the support block and the end cap are provided with the same limiting groove, and the limiting groove fits with the ball bearing.

[0010] Furthermore, the limiting mechanism includes a fixed plate, a movable plate, and a second spring. The fixed plate is fixedly connected to the mounting block. One end of the movable plate moves within the fixed plate. The second spring is installed between the movable plate and the fixed plate. The other end of the movable plate has a slot that cooperates with the support block.

[0011] Furthermore, the support block and the slot have the same chamfer.

[0012] Furthermore, the mounting block has a mounting groove, and the mounting groove has several protrusions. The end cover has a receiving groove that mates with the protrusions. A limiting block one is fixedly connected to the end cover, and a limiting block two is fixedly connected to the movable plate. The limiting block one has a slot two, and the limiting block two mates with the slot two.

[0013] In summary, the beneficial effects of the steering mechanism for an assembly production line in this application are as follows: by setting a mounting block with ball bearings in the empty slot of the worktable of the steering mechanism, the rolling characteristics of the ball bearings are used to greatly reduce the frictional resistance during the transfer of the placement plate. At the same time, the mounting block is evenly distributed along the length and width of the empty slot, so that the ball bearings form a comprehensive and stable support and guiding structure. This ensures that when the placement plate is transferred from the horizontal conveyor belt to the steering mechanism, it will only receive a force in one direction from the vertical transmission belt. After the placement plate has been completely moved to the worktable, it can be smoothly moved to another vertical conveyor belt by pushing it with the worker. By simply setting the last station of the first horizontal conveyor belt and the first station of the second vertical conveyor belt next to the steering mechanism, the jamming phenomenon can be completely avoided, significantly improving the continuity of the assembly production line and ensuring uninterrupted production.

[0016] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0017] like Figures 1 to 7 As shown, a steering mechanism for an assembly line includes two vertical conveyor belts, a steering mechanism 3 is provided on one side of the two horizontal conveyor belts 1, one end of the two horizontal conveyor belts 1 is attached to the steering mechanism 3, and a placement plate 2 can move on the horizontal conveyor belts 1 and the steering mechanism 3.

[0018] The steering mechanism 3 includes a worktable 301, a support frame 302, mounting blocks 303, and ball bearings 304. A slot 4 for mounting the mounting blocks 303 is provided on the worktable 301. Several mounting blocks 303 are fixedly connected to the slot 4, and are simultaneously arranged along the length and width of the slot 4. The ball bearings 304 are rotatably connected to the mounting blocks 303. The placement plate 2 is transported into the steering mechanism 3 by the horizontal conveyor belt 1. The lower surface of the placement plate 2 is in contact with the ball bearings 304. The steering mechanism 3 does not have a drive source. After the placement plate 2 is fully fed into the steering mechanism 3 by the horizontal conveyor belt 1, it only needs to be pushed by the worker at that station. Under the action of force, the placement plate 2 moves on the ball bearings 304. The ball bearings 304 can minimize the friction between themselves and the placement plate 2, allowing the placement plate 2 to easily reach the position of another horizontal conveyor belt 1. It is then assembled by the worker and fed into the second horizontal conveyor belt 1.

[0019] Furthermore, a cavity 5 is provided inside the mounting block 303, and a movable mechanism 6 is installed in the cavity 5. The ball 304 is rotatably connected to the movable mechanism 6. An end cap 7 is detachably connected to the top of the mounting block 303. The end cap 7 cooperates with the movable mechanism 6 to limit the range of motion of the ball 304. One end of the ball 304 extends out from the end cap 7.

[0020] Furthermore, the movable mechanism 6 includes a movable rod 601, a support block 602, a locking block 603, a spring 604, and a limiting mechanism 605. The upper surface of the support block 602 and the lower surface of the end cap 7 are provided with identical limiting grooves 9. When the ball 304 is placed on the support block 602, the limiting groove 9 on the support block 602 fits against the ball 304. When the end cap 7 is installed on the mounting block 303, the limiting groove 9 on the mounting block 303 fits against the ball 304. One end of the movable rod 601 is connected to the lower surface of the support block 602, and the other end of the movable rod 601 extends out of the cavity 5 and passes through the worktable 301. A locking block 603 is fixedly connected to the movable rod 601. The same movable groove 8 is provided on the mounting block 303 and the worktable 301, and the locking block 603 can extend out from the movable groove 8. A spring is installed between the lower surface of the support block 602 and the bottom wall of the cavity 5, and one end of the spring is fixedly connected to the lower surface of the support block 602. The other end of the spring is fixedly connected to the bottom wall of cavity 5, and the diameter of the spring is greater than the length of the locking block 603. When the support block 602 and the end cover 7 limit the ball 304, the movable rod 601 presses the ball 304 against the end cover 7 under the action of the spring, so that the ball 304 is always in the limiting groove 9 on the end cover 7. At this time, there is a 90° angle between the locking block 603 and the movable groove 8, and the locking block 603 is located in cavity 5. A limiting mechanism 605 is provided around the support block 602, and the limiting mechanism 605 is fixedly connected to the inner wall of the cavity.

[0021] Furthermore, a limiting mechanism 605 is provided around the support block 602. The limiting mechanism 605 includes a fixed plate 6051, a movable plate 6052, and a second spring 6053. The fixed plate 6051 is fixedly connected to the inner wall of the cavity 5. One end of the movable plate 6052 slides inside the fixed plate 6051. The second spring 6053 is installed between the end of the movable plate 6052 that extends into the fixed plate 6051 and the fixed plate 6051. One end of the second spring 6053 is fixedly connected to the movable plate 6052, and the other end of the second spring 6053 is fixedly connected to the fixed plate 6051. A slot 10 that fits against the outer side of the support block 602 is provided on the other end of the movable plate 6052. Chamfers are provided on the lower surface of the slot 10 and the upper surface of the support block 602.

[0022] Furthermore, an installation groove 11 is provided on the upper surface of the mounting block 303, and a plurality of protrusions 12 are provided in the installation groove 11. An accommodating groove 13 that mates with the protrusions 12 is provided on the end cover 7. A limiting block 14 is fixedly connected to the end cover 7, and a limiting block 25 is fixedly connected to the movable plate 6052. A slot 2 16 is provided on the limiting block 14, and the limiting block 2 15 mates with the slot 2 16.

[0023] If the ball bearing 304 becomes stuck or wears out and needs to be replaced, simply rotate the movable rod 601 to align the locking block 603 on the movable rod 601 with the movable groove 8. Then pull the movable rod 601 to move the locking block 603 from the movable groove 8 to below the worktable 301. After rotating 90°, the locking block 603 will press against the lower surface of the worktable 301 under the action of the spring 604. When the movable rod 601 is pulled, the support block 602 will move with the movable rod 601. When the top of the support block 602 is lower than the lower surface of the movable plate 6052, the spring 6053 will quickly rebound, causing the movable plate 6052 to support the ball bearing 304. At this time, the position of the ball bearing 304 is restricted. At the same time, the limiting block 15 on the movable plate 6052 will also move horizontally, causing the limiting block 15 to disengage from the locking groove 16. At this time, the end cover 7 can be removed. After the end cover 7 is removed, the ball bearing 304 can be removed for replacement or maintenance.
