Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a conveyor line for the vertical return of parts carriers on an assembly line for small automotive parts. Background Technology

[0002] With the continuous development of industrial technology, intelligent automation is being applied more and more widely in manufacturing. In practical applications, this intelligent automated production line has demonstrated significant advantages. It greatly reduces manual intervention, lowers labor intensity, and improves production safety. Workers no longer need to perform heavy and dangerous tasks, but can instead focus on monitoring and managing the operation of the production line.

[0003] Many automotive parts, such as tiny components the size of a coin, especially valve bodies for shock absorbers, require high assembly precision. Intelligent automated production lines necessitate the use of parts carriers to load, position, and orient parts for assembly, ensuring precise automated assembly at each station. Therefore, a conveyor system is needed that allows the parts carriers to automatically circulate back after passing through all stations, working in conjunction with intelligent automation to complete the intelligent automated assembly of various small components. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an assembly line with a circulating conveyor to solve the problem of circulating conveyor of small auto parts assembly carriers, so as to cooperate with intelligent automated equipment to complete the automatic assembly work.

[0005] To solve the above problems, the technical solution of this utility model is: the assembly line includes a return conveyor line on the work platform for conveying parts carriers;

[0006] The return conveyor line includes an upper conveyor belt and a lower conveyor belt arranged vertically. The upper conveyor belt and the lower conveyor belt have opposite conveying directions. Both ends of the upper conveyor belt and the lower conveyor belt are provided with lifting pallets for lifting the part carrier. The bottom of the lifting pallet is provided with a lifting cylinder. The upper conveyor belt is provided with limiting blocks on both sides of each station for inserting or pulling out the part carrier. The limiting blocks are connected to a transverse cylinder that drives them in and out.

[0007] The upper conveyor belt, the lower conveyor belt, the lifting cylinder, and the transverse cylinder are all connected to a control unit.

[0008] A more specific embodiment of the above technical solution is that both the upper conveyor belt and the lower conveyor belt are belt conveyor belts.

[0009] Furthermore: the transverse cylinder on the side of the upper conveyor belt is mounted on a transversely arranged mounting plate; the limiting block has a downwardly bent end, which is connected to the power output end of the transverse cylinder; the part carrier has a groove in the middle for positioning and placing parts; and the two sides of the part carrier have slots for the limiting block to be inserted.

[0010] Furthermore: a pushing cylinder is provided next to the lifting pallet for pushing the part carrier into the upper conveyor belt and the lower conveyor belt, and a laser sensor is provided next to each of the limiting blocks. The laser sensor and the pushing cylinder are both connected to the control unit.

[0011] Furthermore, the upper conveyor belt and the lower conveyor belt are mounted on the working platform via multiple support seats.

[0012] Furthermore, each of the support bases includes a pair of L-shaped support plates on both sides of the upper conveyor belt and the lower conveyor belt. The support plates are provided with a vertical portion for mounting the upper conveyor belt and the lower conveyor belt and a horizontal portion for connecting to the working platform.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0014] This assembly line uses vertically arranged conveyor belts, with the upper and lower belts moving in opposite directions. This allows the part carrier to be transported along the workflow direction of the workstation on the upper conveyor belt and then flow back in the opposite direction on the lower conveyor belt. Lifting cylinders, lifting pallets, and pushing cylinders at both ends of the conveyor belts facilitate the movement of the part carrier between the upper and lower belts. Limiting blocks and transverse cylinders that drive the limiting blocks in and out insert into the slots of the part carrier when it reaches its designated position, stopping it. After assembly, the limiting blocks extend from the part carrier, allowing it to continue moving between workstations. A laser sensor next to the limiting blocks detects when the part carrier is in position and controls the block's movement via a control unit. The use of the vertically arranged conveyor belts, lifting cylinders and pallets, limiting blocks, and laser sensors enables automatic start / stop and automatic return of the part carrier.

[0015] The upper and lower return conveyor lines of this assembly line start and stop the lifting cylinders to raise and lower the parts carriers according to their positions on the upper and lower conveyor belts, thereby controlling the return state of the parts carriers. In conjunction with other intelligent automatic assembly equipment such as robots on the work platform, the entire assembly process is made intelligent and automated, which greatly reduces manual intervention and improves the consistency and stability of the assembly. Through precise control and monitoring, the assembly accuracy and quality of the shock absorber components are ensured. Attached Figure Description

[0020] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0021] like Figures 1 to 3 The assembly line shown includes a return conveyor system on the work platform 100 for transporting part carriers 11. The return conveyor system comprises an upper conveyor belt 4 and a lower conveyor belt 5 arranged vertically. Both the upper and lower conveyor belts are driven by a motor 3. The upper and lower conveyor belts transport parts in opposite directions, allowing the part carriers to return to the work station's forward direction on the lower conveyor belt after being transported along the work process direction on the upper conveyor belt. The upper conveyor belt 4 and lower conveyor belt 5 are mounted on the work platform 100 via multiple support seats 10. Each support seat 10 includes a pair of L-shaped support plates on both sides of the upper and lower conveyor belts. The support plates have a vertical portion for mounting the upper and lower conveyor belts and a horizontal portion connected to the work platform.

[0022] Each station on the upper conveyor belt 4 has a limiting block 8 on both sides for inserting or removing part carriers. The limiting block is connected to a transverse cylinder 7 that drives it in and out. The transverse cylinder 7 is mounted on a transversely positioned mounting plate 6, one end of which is bent and mounted on the side of the upper conveyor belt 4. The limiting block 8 has a downward-bent end connected to the power output end of the transverse cylinder 7. The part carrier 11 has a groove in the middle for positioning and placing parts, and slots on both sides for the limiting blocks 8 to be inserted. Each limiting block 8 is accompanied by a laser sensor 9 for detecting whether the part carrier is in position. After the part carrier is positioned on the upper conveyor belt, the power output ends of the transverse cylinders on both sides of the upper conveyor belt drive the limiting blocks to insert into the slots on both sides of the part carrier, preventing the part carrier from moving. After the robot at that station has finished assembling the part, the transverse cylinders drive the limiting blocks to be pulled out of the slots of the part carrier, and the part carrier continues to move on the upper conveyor belt.

[0023] Both ends of the upper conveyor belt 4 and the lower conveyor belt 5 are equipped with lifting pallets 2 for lifting the part carrier 11. A lifting cylinder 1 is located at the bottom of the lifting pallet 2, and a pushing cylinder 12 is located beside the lifting pallet 2 to push the part carrier 11 onto the upper and lower conveyor belts. After the part carrier 11 is transported along the work process direction on the upper conveyor belt, the operator can remove the assembled part components from the part carrier on the upper conveyor belt. The empty part carrier is squeezed onto the lifting pallet 2 at the rear end of the conveyor belt by the conveying force of the upper conveyor belt 4. The lifting cylinder under the lifting pallet 2 lowers until the lifting pallet 2 is level with the conveying surface of the lower conveyor belt 5. The empty part carrier is then pushed into the lower conveyor belt by the pushing cylinder 12. Alternatively, the operator can manually push the part carrier into the lower conveyor belt as needed. The lower conveyor belt allows for better adjustment and control of the assembly progress. A lifting cylinder raises the lifting pallet to the level of the upper conveyor belt. Empty parts carriers on the lower conveyor belt flow back in the opposite direction to the front of the workstation's workflow direction, i.e., the front end of the lower conveyor belt. The empty parts carriers are squeezed by the conveying force of the lower conveyor belt onto the lifting pallet at the front end of the conveyor belt. At this point, the lifting pallet is level with the conveying surface of the lower conveyor belt. Then, the front lifting cylinder raises the lifting pallet along with the empty parts carriers to the level of the conveying surface of the upper conveyor belt. A pushing cylinder pushes the empty parts carriers into the upper conveyor belt. The empty parts carriers circulate between three workstations on the upper conveyor belt. The front lifting cylinder lowers the lifting pallet back to its original position. In this way, the parts carriers rotate back and forth on the upper and lower conveyor belts.

[0024] The drive motors 2 of the upper conveyor belt 4 and the lower conveyor belt 5, the lifting cylinder 1, and the laser sensor 9 are all connected to a control unit. The control unit is connected to a data analysis unit, which collects and analyzes data captured by the camera to accurately determine the distribution and location of parts, as well as the status and position of the robot's material handler, in order to perform precise assembly. The control unit is connected to a control panel.

[0025] This assembly line uses vertically arranged conveyor belts, with the upper and lower belts moving in opposite directions. This allows the part carrier to be transported along the workflow direction of the workstation on the upper conveyor belt and then flow back in the opposite direction on the lower conveyor belt. Lifting cylinders and lifting pallets at both ends of the conveyor belts facilitate the movement of the part carrier between the upper and lower belts. Limiting blocks and lateral cylinders that drive the limiting blocks insert into the slots of the part carrier when it reaches its position, stopping it. After assembly, the limiting blocks extend out of the part carrier, allowing it to continue moving between workstations. A laser sensor next to the limiting blocks detects when the part carrier is in position and controls the block's movement via a control unit. The use of the vertically arranged conveyor belts, lifting cylinders and lifting pallets, limiting blocks, and laser sensors enables automatic start / stop and automatic return of the part carrier.

[0026] The upper and lower return conveyor lines of this assembly line start and stop the lifting cylinders according to the position of the parts carriers on the upper and lower conveyor belts to control the return state of the parts carriers. In conjunction with other intelligent automatic assembly equipment such as robots on the work platform, the entire assembly process is made intelligent and automated, which greatly reduces human intervention and improves the consistency and stability of assembly. Through precise control and monitoring, the assembly accuracy and quality of shock absorber components are ensured.

[0027] Adopting intelligent automated assembly technology can improve a company's production efficiency and product quality, reduce production costs, and enhance its competitiveness. In today's increasingly competitive market, possessing advanced production technology is crucial for a company's survival.
