Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an automated assembly equipment for assembling automotive shock absorber linkage assemblies. Background Technology

[0002] The connecting rod assembly of a shock absorber consists of multiple nested parts on the connecting rod cylinder in a specific order. These parts are mostly composed of small, irregularly shaped components. For example, the valve body assembly is made up of eight interlocking parts. These eight parts have different shapes, especially five of them which are flat and very small (about the size of a penny). They are lightweight, small in size, have holes in the center, and various locking positions around the perimeter. They need to be interlocked sequentially in a specific direction. The valve seat assembly formed after interlocking must then be assembled onto the connecting rod cylinder of the shock absorber and interlock with it. Therefore, the assembly precision requirements for these components are relatively high, and the assembly precision requirements for the entire shock absorber connecting rod assembly are also relatively high.

[0003] Currently, connecting rod assembly is generally done manually. The components are first assembled, then the required parts and components are assembled onto the connecting rod cylinder according to specifications, and finally, a pass / fail test is performed. This manual assembly method is not only extremely inefficient, but the assembly precision also decreases with the fatigue level of the assemblers, resulting in poorly guaranteed assembly quality. Furthermore, the consistency and stability of assembly work per person per batch is low due to the large number of assemblers. Therefore, the assembly efficiency and quality of these small automotive parts have become a bottleneck in automotive parts production, consistently hindering the development of the automotive parts industry.

[0004] The problem to be solved by this utility model is to provide an assembly line for shock absorber connecting rod assemblies, so as to solve the problems of low assembly efficiency and unstable assembly quality of existing small automotive parts such as shock absorber connecting rod assemblies.

[0005] To solve the above problems, the technical solution of this utility model is: the shock absorber connecting rod assembly line includes a return conveyor line on the work platform for conveying parts carriers and multiple assembly units arranged sequentially along the return conveyor line. At the end of the return conveyor line, there is a horizontally rotating turntable, and multiple assembly units are arranged sequentially around the turntable.

[0006] The assembly unit includes a robot with a picker and a camera above the robot, with a material tray placed next to the robot; the picker is a clamp or a magnetic chuck.

[0007] 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.

[0008] The turntable is evenly provided with multiple upper clamps driven by clamping cylinders for clamping the upper part of the connecting rod cylinder. Below the turntable, below each of the upper clamps, there is a lower clamp driven by a clamping cylinder for clamping the lower part of the connecting rod cylinder. On one side below the lower clamps, there is an upward push cylinder for pushing the connecting rod cylinder upward during assembly. A camera is provided above the turntable.

[0009] The robot, the camera, the vibrator, the upper and lower conveyor belts, the lifting cylinder, the lateral cylinder, the upward pushing cylinder, the clamping cylinder, and the motor that drives the turntable to rotate horizontally are all connected to a control unit.

[0010] A more specific solution to the above technical solution could be that the robot is a six-degree-of-freedom robot and is mounted on the work platform via a mounting base.

[0011] Furthermore: the assembly unit is provided with a discharge hopper with an inclined discharge surface next to the material tray, and the bottom of both the discharge hopper and the material tray is provided with the vibrator.

[0012] Furthermore, both the upper conveyor belt and the lower conveyor belt are belt conveyor belts.

[0013] 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; the two sides of the part carrier have slots for inserting the limiting block; each limiting block is equipped with a laser sensor; and the lifting plate is equipped with a pushing cylinder for pushing the part carrier into the upper and lower conveyor belts. Both the laser sensor and the pushing cylinder are connected to the control unit.

[0014] Furthermore, the upper conveyor belt and the lower conveyor belt are mounted on the working platform via multiple support seats.

[0015] Furthermore: the turntable is mounted on a turntable mounting base on a lower, low-level platform next to the working platform via a vertically erected spindle, and the assembly unit around the turntable is located on a higher working platform next to the turntable, which is higher than the working platform.

[0016] Furthermore, the lower clamp next to the turntable and the clamp cylinder that drives its movement are mounted on the low-level platform via a support.

[0017] Furthermore: the top of the upward-pushing cylinder next to the turntable is provided with an upward-pushing plate for pushing it upward from the bottom of the connecting rod cylinder. The upward-pushing cylinder is located on the low horizontal platform. The camera above the turntable is located on the horizontal bar of the upper part of the vertically installed column on the low horizontal platform.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0019] 1. This shock absorber linkage assembly line uses a return conveyor line and a horizontally rotating turntable on the work platform as conveying mechanisms. Multiple assembly units equipped with robots are arranged sequentially along the return conveyor line and turntable to automatically transport and move the completed parts to multiple stations on the return conveyor line and turntable. The robots at multiple stations automatically pick up the parts and assemble them sequentially at multiple stations.

[0020] 2. The assembly unit of this shock absorber linkage assembly line uses vibrators at the bottom of the discharge hopper and the material tray to disperse the stacked parts. The inclined discharge surface of the vibrator and the discharge hopper simultaneously disperses the parts and transports them to the material tray. The camera above captures the state of the dispersed parts and the position and direction of the robot picking up the parts. The return conveyor line controls whether the upper and lower conveyor belts continue to rotate by checking whether the robots assembling the parts on the part carriers at multiple workstations have completed their assembly. The lifting cylinders are activated and deactivated according to the position of the part carriers on the upper and lower conveyor belts to control the return state of the part carriers.

[0021] 3. Each station of the turntable in this shock absorber connecting rod assembly line is equipped with upper and lower clamps driven by clamp cylinders to hold the upper and lower parts of the connecting rod cylinder. The turntable rotates horizontally, allowing each station to move between multiple assembly units. The adjacent robot automatically picks up the parts and assembles them sequentially on the connecting rod cylinder at the corresponding station according to the process requirements, automatically completing the assembly process. When the finally assembled connecting rod assembly is driven back to the first station of the turntable, it can be taken out by the operator and another connecting rod cylinder to be assembled can be placed on it.

[0022] The entire process of material handling, assembly, and transfer of the connecting rod assembly in this shock absorber assembly line is fully automated. The intelligent and automated assembly process significantly reduces manual intervention, improving assembly consistency and stability. Precise control and monitoring ensure the assembly accuracy and quality of shock absorber components. Furthermore, the high degree of automation in the production line increases capacity, enabling continuous and efficient production, greatly shortening the assembly cycle, and improving production efficiency and capacity.

Detailed Implementation

[0027] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0028] like Figures 1 to 3 The shock absorber linkage assembly line shown includes a return conveyor line on a work platform 100 for transporting parts carriers 11, and three assembly units arranged sequentially along the return conveyor line. At the end of the return conveyor line is a horizontally rotating turntable 50, with two assembly units arranged sequentially around the turntable 50. Using the return conveyor line and the horizontally rotating turntable on the work platform as the conveying mechanism, and with multiple assembly units equipped with robots arranged sequentially along the return conveyor line and turntable, the completed parts are automatically transported and moved between multiple stations on the return conveyor line and turntable. Robots at multiple stations automatically pick up parts and assemble them sequentially at these stations.

[0029] The assembly unit includes a robot 40 with a picker and a camera 23 above the robot. The robot 40 is a six-degree-of-freedom robot and is mounted on the work platform 100 via a mounting base 43. The camera 23 is a hyperspectral camera and is mounted on a crossbar 22 on the upper part of the column 21 on one side of the robot. A discharge hopper 31 with an inclined discharge surface is provided next to the robot 40, and a material tray 32 is provided on one side of the bottom of the discharge hopper. The camera 23 is located above the robot and is mounted on the crossbar 22 on the upper part of the column on one side of the robot. It can accurately capture the gathering and dispersing status of the robot and all parts on the discharge hopper and material tray below it. The entire robot movement process includes the angle and direction of picking up parts and the position and direction of the assembled parts on the part carrier extending to the return conveyor line. Both the bottom of the discharge hopper 31 and the material tray 32 are equipped with oscillators 33; the oscillators 33 vibrate and disperse the parts stacked on the discharge hopper 31 and the material tray 32. The inclined discharge surface of the discharge hopper allows the parts stacked on the discharge hopper to fall into the material tray by their own weight and the vibration force of the oscillator. Under the combined action of the two forces, the parts are further dispersed by falling and vibrating.

[0030] The turntable 50 is mounted on a turntable mounting base 51 on a lower horizontal platform 90 next to the work platform 100 via a vertically set spindle. The assembly unit around the turntable 50 is located on a higher work platform 95 next to the turntable, which is higher than the work platform. The spindle is connected to a motor and a reducer. Multiple upper clamps 53 driven by clamp cylinders 52 are evenly arranged around the turntable 50 for clamping the upper part of the connecting rod cylinder. Below the turntable 50, below each upper clamp, there is a lower clamp 54 driven by a clamp cylinder for clamping the lower part of the connecting rod cylinder. On one side below the lower clamp 54, there is an upper push cylinder 55 for pushing the connecting rod cylinder upward during assembly. The lower clamps next to the turntable and the clamp cylinders that drive their movement are mounted on the lower horizontal platform 90 via supports 57. The top of the push cylinder 55 next to the turntable 50 is provided with a push plate 56 for pushing it up from the bottom of the connecting rod cylinder. The push cylinder 55 is located on the low horizontal platform 90. A camera 23 is provided above the turntable 50. The camera is located on the horizontal bar 22 of the vertical column 21 on the low horizontal platform 90.

[0031] The return conveyor line includes 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 convey in opposite directions, so that after the parts carrier is transported along the workflow direction of the station on the upper conveyor belt, it can return to the front of the workstation in the opposite direction on the lower conveyor belt. The upper conveyor belt 4 and the lower conveyor belt 5 are mounted on the work platform 100 by 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 part for mounting the upper and lower conveyor belts and a horizontal part for connecting to the work platform.

[0032] 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 assembles 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.

[0033] 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.

[0034] The robot 40, camera 23, vibrator 33, and drive motors 2 for the upper conveyor belt 4 and lower conveyor belt 5, as well as the lifting cylinder 1, laser sensor 9, upward pushing cylinder 55, clamping cylinder 52, and the motor for the horizontal rotation of the drive turntable 50, are all connected to a control unit. This 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, for precise assembly. The control unit is connected to a control panel.

[0035] The return conveyor line has three stations. Each robot can have one or more grippers. These grippers can be clamps 41 of different shapes and specifications, or magnetic chucks 42 of different shapes and diameters. Alternatively, a single robot can have both clamps 41 and magnetic chucks 42. For example, the robot at the first station has five magnetic chucks 42 of different shapes and specifications to pick up parts of different diameters. The robot at the second station has magnetic chucks 42 as its grippers. The robot at the third station has multiple grippers, including magnetic chucks 42 and clamps 41. The clamps 41 can hold parts externally or open from the inside to hold them. The first and third stations of the return conveyor line have a material tray with multiple slots 34-1, which is a multi-slot material tray 34. Each slot holds a part. There is no discharge hopper next to the multi-slot material tray 34. The bottom of the multi-slot material tray 34 can also be equipped with a vibrator 33 to vibrate the parts that are not placed flat by hand into place.

[0036] The turntable 50 has four workstations, and two assembly units are set up next to the four workstations. Each assembly unit has two multi-slot trays 34 next to the robot. Each multi-slot tray 34 holds a type of part. Each robot can carry one picker or multiple pickers. Multiple pickers can be clamps 41 of different shapes and specifications, or they can be magnetic chucks 42 of different shapes and diameters. Alternatively, a robot can carry both clamps 41 and magnetic chucks 42 at the same time to pick up multi-slot trays 34 of different shapes and sizes or parts in trays 34. The clamps 41 can hold parts externally or open from the inside of the parts to hold them. Each station on the turntable is equipped with upper and lower clamps driven by clamp cylinders to hold the upper and lower parts of the connecting rod cylinder. The turntable rotates horizontally, allowing each station to move between two assembly units. Two robots next to it automatically pick up parts and assemble them sequentially on the connecting rod cylinder at the corresponding station according to the process requirements, automatically completing the assembly process. When the finally assembled connecting rod assembly is driven back to the first station of the turntable by the turntable, it can be taken out by the operator and another connecting rod cylinder to be assembled can be placed on it. The operator can also assemble the first part on the connecting rod cylinder at the same time.

[0037] When in use, the staff only needs to place a certain number of parts in the discharge hoppers of all workstations in sequence according to the assembly process, make the corresponding settings on the control panel, and the control program in the control unit will control the parts according to the parameters.

[0038] The return conveyor line starts, and the part carriers move between three stations on the upper conveyor belt and the lower conveyor belt. When the laser sensor at the first station detects a part carrier, the camera at the first station captures the state of the parts piled up or the parts placed stably in the tray. The robot at the first station then uses its gripper to pick up a single, isolated part from the tray, rotates it horizontally to a certain direction, and places it into the groove of an empty part carrier. The gripper releases and rises, and the robot at the first station returns to the tray to pick up another part and assemble it onto the part carrier at the first station. The part carrier with two parts moves to the second station, while another empty part carrier is transported to the first station by the upper conveyor belt. When the laser sensor at the second station detects a part carrier, the camera at the second station captures the state of the parts piled up or the parts placed stably in the tray. The robot at the second station uses its magnetic suction head to pick up a single, isolated part from the tray. Individual, scattered or stably placed parts are assembled into a parts carrier. The magnetic pick-up head disengages, the electromagnetic release mechanism lifts the robot at the second station, and the robot returns to the tray to pick up another part for assembly. The parts carrier continues to flow to the third station. While assembly is underway at the second station, empty parts carriers at the first station continue to be loaded with parts. Similarly, when the laser sensor at the third station detects a parts carrier, the camera at the third station captures the state of the parts in the tray—whether they are scattered or stably placed—and controls the robot at the third station to pick up any individual, scattered or stably placed parts from the tray for assembly. Then, the rotating pick-up device uses the magnetic pick-up head to extract another part for assembly. The assembly, containing multiple parts, moves towards the rear end of the upper conveyor belt along with the parts carrier. The operator removes the assembly, and the empty parts carrier descends to the lower conveyor belt via a lifting pallet and lifting cylinder, where it is transported back to the front end of the lower conveyor belt. This process of automatic assembly, repeated continuously by the return conveyor line and assembly units on the work platform, allows for simultaneous assembly at multiple stations, enabling rolling production.

[0039] The turntable has four stations. The station closest to the edge of the machine on the low-level platform can be designated as the first station. At this station, the operator clamps the connecting rod cylinder to be assembled using the upper and lower clamps. The first part can also be assembled on the connecting rod cylinder simultaneously. This could be a component assembled on the return conveyor line. Once the camera on the turntable has captured the completion of assembly work at all four stations, the turntable rotates to the second station. The camera at this station captures the state of the parts in the tray—whether they are scattered or placed stably—and controls the robot at this station to pick up any independent parts appearing in the tray. The connecting rod cylinder is assembled from discrete, single parts or stably placed single parts. When a part requiring pressing is reached, an upward-pushing cylinder pushes the connecting rod cylinder from the bottom, pressing the part together. The robot then returns to the tray to pick up another part for assembly. While the robot is assembling at the second station, a new connecting rod assembly is assembled at the first station, which is then removed by the operator before a new connecting rod cylinder is installed. This process continues as the turntable rotates, and the assembly units continue assembling parts, achieving automated assembly of the connecting rod assembly. Multiple assembly units can perform assembly simultaneously, enabling rolling production.

[0040] Both the return conveyor line and the turntable can be used for simultaneous assembly and rolling production to speed up assembly efficiency.

[0041] This shock absorber linkage assembly line is centered on intelligent technology, integrating advanced video monitoring, sensor technology, automated control technology, and data analysis technology. The production line can sense various parameters during the production process in real time, such as pressure, speed, position, and angle, and automatically adjust according to preset programs to ensure production stability and high quality. Simultaneously, through big data analysis, the production line can continuously optimize production processes, improve production efficiency, and reduce production costs. This not only enhances the core competitiveness of enterprises, increases market share, and achieves sustainable development, but also deeply integrates with emerging technologies such as artificial intelligence and the Internet of Things, bringing more innovation and transformation to the industrial sector.

[0042] This shock absorber linkage assembly line is highly flexible and adaptable, meeting the assembly needs of different types of shock absorber components. The equipment adopts a modular design, allowing for rapid assembly and adjustment according to production requirements, thus improving production efficiency and equipment utilization.

[0043] 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.
