Description

Technical Field

[0001] This utility model relates to the field of logistics racks, specifically to a tire logistics rack for automobile assembly. Background Technology

[0002] Tire assembly is a crucial process in automobile manufacturing. Currently, tire assembly typically involves a robotic arm gripping a tire from a conveyor belt or roller bed, moving it to the target location on the vehicle to be assembled, and then tightening it. For ease of transport, the tires on the conveyor belt or roller bed are initially laid flat. Therefore, the robotic arm needs to adjust its position first, gripping the flat tire, rotating it to an upright position, and then moving it to the target location. Furthermore, the height of the roller bed or conveyor belt is usually different from the height of the target tire location; therefore, the robotic arm also needs to adjust its height after gripping the tire during assembly. These frequent adjustments to the robotic arm's position and height not only extend the process time and waste energy but also reduce the robotic arm's lifespan to some extent. Summary of the Invention

[0003] To address the aforementioned problems, this utility model proposes a tire logistics rack for automobile assembly, specifically comprising:

[0004] A tire logistics rack for automobile assembly includes a base, which is installed at the bottom of a support. A guide, a side frame, and a support plate are arranged sequentially from top to bottom on one side of the support. The support is characterized in that the top of the support is a roller bed, an arc-shaped guide is installed at the end of the roller bed, side frames are installed on both sides below the guide, and a support component is installed at the end of the side frame.

[0005] Preferably, a guide rod is installed on the guide section, and a cylindrical guide roller is rotatably installed on the top of the guide rod.

[0006] Preferably, guard plates are provided on both sides of the roller bed, and the opening formed between the guard plates on both sides gradually closes into the guide assembly.

[0007] Preferably, the support assembly includes an opening and closing motor, which is installed on the top of the side frame. The output end of the opening and closing motor is connected to a rotating shaft, which passes through the side frame and is rotatably connected to the side frame. A support rod is provided laterally on the rotating shaft to support the tire.

[0008] Preferably, a laser sensor is installed on one side of the side frame, and a reflector is installed at the corresponding position on the opposite side frame. The laser sensor is electrically connected to the roller bed.

[0009] Preferably, the height of the support plate is adjustable.

[0010] Preferably, the support plate has a groove on its edge, and a switch assembly is provided in the groove. The switch assembly includes a toggle mechanism and a rotating shaft. The toggle mechanism is triangular, with one inclined side facing the tire direction. The bottom of the toggle mechanism is rotatably connected to the support plate through the rotating shaft.

[0011] Preferably, torsion springs are installed at corresponding positions of the actuating mechanism, the rotating shaft, and the support plate. The torsion springs keep the actuating mechanism in the closed state, in which the top of the actuating mechanism protrudes from the support plate by a certain distance.

[0012] Preferably, an electric switch is installed on the side of the actuating mechanism facing away from the tire. The electric switch is electrically connected to the opening and closing motor and can control the start and stop of the opening and closing motor.

[0013] Preferably, the support plate has a plurality of rollers arranged closely on its surface.

[0014] The beneficial effects are as follows: This tire logistics rack, through the structure of guide section, side frame and support plate, changes the tire from a flat state to a vertical state, and keeps its height consistent with the height of the position to be assembled. During assembly, the robotic arm only needs to directly grab the tire and move it to the target position for assembly, which eliminates the steps of posture adjustment before grabbing and height adjustment during the grabbing process, saves process time, improves production efficiency and reduces the burden on the robotic arm.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0022] like Figure 1-5 As shown, this utility model provides a tire logistics rack for automobile assembly, specifically including a base 1, which is mounted on a support 2 for fixing the entire logistics rack to the ground using anchor bolts. The support 2 is approximately "U"-shaped, with a guide section 3, a side frame 10, and a support plate 8 arranged sequentially from top to bottom on one vertical section. The top of the support 2 is a roller bed 5 for tire conveying. Guard plates 4 are provided on both sides of the roller bed 5, and the opening formed between the guard plates 4 gradually narrows towards the guide assembly 6. The guard plates 4 serve two purposes: first, to prevent the tire from slipping during transport on the roller bed 5; and second, to guide the tire to the guide assembly 6, thereby ensuring that it falls between the guide assemblies 6.

[0023] At the end of the roller bed 5 in the forward direction, an arc-shaped guide section 3 is installed. A certain number of guide rods 61 are installed on the guide section 3 at certain intervals. A cylindrical guide roller 62 is rotatably mounted on the top of each guide rod 61. When the tire reaches the end of the roller bed, it will slide off the arc-shaped guide section 3. At this time, the top of the tire contacts the guide roller 62. Under the guidance of the guide roller 62, the tire slides vertically downward and finally falls onto the support plate 8.

[0024] To prevent the tire from tipping over or rolling after falling onto the support plate 8, side frames 10 are installed on both sides of the tire below the guide section 3 to limit lateral rolling. A support assembly 7 is installed at the end of the side frame 10 to prevent tire tipping. Specifically, the support assembly 7 includes an opening / closing motor 71, mounted on the top of the side frame 10. The output end of the opening / closing motor 71 is connected to a rotating shaft 72, which passes through the side frame 10 and is rotatably connected to it. A support rod 73 is laterally mounted on the rotating shaft 72 to support the tire. In use, the opening / closing motor 71 drives the rotating shaft 72 to rotate, causing the support rod 73 to swing laterally, thus supporting the tire, or opening it to allow the robotic arm to remove the tire. To facilitate robotic arm operation, the length of the support rod 73 should be adjusted according to the tire size, supporting the tire on both sides while leaving space in the middle of the tire for the gripping mechanism on the robotic arm to enter.

[0025] To detect whether there is a tire at the support assembly 7 and thus control the start and stop of the roller bed, a laser sensor 11 is installed on one side frame 10, and a reflector 12 is installed at the corresponding position on the opposite side frame 10. The laser sensor 11 is electrically connected to the roller bed 5 through a corresponding control device (PLC, etc.).

[0026] To facilitate the opening and closing of the support rod 73, a switch assembly 9 is installed on the edge of the support plate 8. Specifically, a slot is cut into the support plate 8, and the switch assembly 9 is installed in the slot. The switch assembly 9 includes an actuating mechanism 91 and a rotating shaft 92. The actuating mechanism 91 is triangular, with one inclined side facing the tire. The bottom of the actuating mechanism 91 is rotatably connected to the support plate 8 via the rotating shaft 92. Torsion springs (not shown in the figure) are installed at corresponding positions on the actuating mechanism 91, the rotating shaft 92, and the support plate 8. The torsion springs keep the actuating mechanism 91 in the closed state, in which the top of the actuating mechanism 91 protrudes a certain distance from the support plate 8. An electric switch 93 is installed on the side of the actuating mechanism 91 facing away from the tire. The electric switch 93 is electrically connected to the opening and closing motor 71 and can control the start and stop of the opening and closing motor 71. In addition, to prevent the tire from pressing on the switch assembly 9 when it falls, the switch assembly 9 should be located at the edge of the support plate 8.

[0027] Furthermore, to reduce the burden on the robotic arm, the height of the support plate 8 on the bracket 2 should be designed in advance according to the working conditions of the car assembly site, so that the center height of the tire on the support plate 8 is consistent with the target position of the tire on the car to be assembled, thereby eliminating the need for the height adjustment step of the robotic arm. Alternatively, the support plate 8 can be designed as a height-adjustable structure.

[0028] The specific operating principle of this tire logistics rack is explained as follows: During operation, the roller bed 5 is started, and the tire moves with the roller bed. Upon reaching the end of the roller bed, the tire falls vertically onto the support plate 8 under the action of the guide assembly 6. At this time, the laser sensor 11 detects the presence of the tire and controls the roller bed 5 to stop running, preventing further tire falls. The support assembly 7 remains normally closed, and the support rod 73 is closed to prevent the tire from tipping over. When the robotic arm needs to pick up the tire, the gripping assembly on the robotic arm extends into the tire's central hole, grips the tire, and removes it horizontally. During removal, the tire moves horizontally, and its bottom touches the actuating mechanism 91. The actuating mechanism 91 tilts and presses the electric switch 93, which controls the opening and closing motor 71 to start, driving the rotating mechanism 72 to rotate, thereby opening the support rod 73. The robotic arm can then pick up the tire for assembly. After the tire is picked up, the actuating mechanism 91 resets under the action of the torsion spring, the state of the electric switch 93 changes, and the opening and closing motor 71 restarts, closing the support rod 73. Simultaneously, as the tire is clamped away, the state of laser sensor 11 also changes, controlling the roller bed 5 to run again, thereby moving the next tire to guide assembly 6. This process is repeated to complete tire assembly.

[0029] The specific control principles of each switch, sensor, motor, etc. in this device are well-known technologies and can be achieved through common automatic control components such as frequency converters and PLCs, so they will not be described in detail here.

[0030] Since the robotic arm moves horizontally when removing the tire, to reduce friction between the bottom of the tire and the support plate 8, such as... Figure 5 As shown, multiple roller rows 13 can be densely arranged on the surface of the support plate 8. When friction occurs, the roller rows rotate to reduce damage to the bottom of the tire.

[0031] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
