Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an automatic assembly method for assembling an automobile shock absorber connecting rod component. Background Art

[0002] The connecting rod assembly of the shock absorber includes multiple parts assemblies nested in a certain order on the connecting rod cylinder. Most of these parts assemblies are small and of various shapes. For example, the valve body assembly is composed of eight parts that are interlocked with each other. These eight parts are of different shapes, especially five of them are flat and very small (such as the size of a penny), very light, small in size, with a hole in the middle and various positions around them. They need to be interlocked in a specific direction in sequence, and the valve seat assembly formed after interlocking must also be assembled on the connecting rod cylinder of the shock absorber and interlocked with the connecting rod cylinder. Therefore, the assembly accuracy requirements of these components are relatively high, and the assembly accuracy requirements of the entire shock absorber connecting rod assembly are relatively high.

[0003] At present, the assembly of connecting rod components is generally done manually, and then the required parts and components are assembled on the connecting rod cylinder as required, and finally the qualified test is carried out. In addition to the very low assembly efficiency, the assembly accuracy of this manual assembly is also reduced with the fatigue of the assembler. The assembly quality cannot be well guaranteed, and the consistency and stability of each assembly by a large number of assemblers are also low. Therefore, the assembly efficiency and quality of such small parts in auto parts have become the production bottleneck of auto parts, which has always restricted the development of the auto parts industry. Summary of the invention

When the laser sensor on each workstation senses the parts carrier, the camera on the workstation captures the scattered state of the parts in the tray or the stable state of the parts, and controls the robot to pick up the single part that is independently scattered or the single part that is stably placed in the tray, and puts it into the groove of the parts carrier for assembly. After that, the robot returns to the tray to continue to pick up the next part for assembly. After the last workstation is assembled, the assembly with multiple parts moves to the rear end along with the parts carrier on the upper conveyor belt, and the empty parts carrier after taking out the assembly continues to circulate on the reflow conveyor line. The multiple assembly units of the reflow conveyor line on the working platform automatically assemble the components repeatedly in this way. A certain station of the turntable is set as the first station, and the connecting rod cylinder to be assembled is clamped on the upper and lower clamps of the station. The camera on the turntable captures that the assembly work of all stations has been completed, and the turntable is rotated to move from the first station to the second station. The camera of the station shows that parts are scattered or placed stably in the tray. The robot of the station is controlled to pick up a single part that is independently scattered or a single part that is placed stably in the tray to assemble the connecting rod cylinder. The robot of the station returns to the tray to continue picking up the next part for assembly. When the robot at the second station is assembling, a new connecting rod assembly is assembled at the first station and then removed, and then a new connecting rod cylinder to be assembled is installed. In this way, the turntable multi-station continues to rotate, and the assembly unit continues to assemble parts.

The robots at multiple stations automatically pick up parts and assemble them at multiple stations in sequence.

[0016] 2. The assembly unit of the shock absorber connecting rod assembly assembly method vibrates the stacked parts through the oscillator at the bottom of the discharge hopper and the tray.

DETAILED DESCRIPTION

[0020] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings: The shock absorber connecting rod assembly assembly method comprises assembling the connecting rod assembly by using a connecting rod assembly assembly line.

[0021] Connecting rod assembly line Figures 1 to 3 As shown, it includes a return conveyor line for conveying part carriers 11 on a work platform 100 and three assembly units arranged in sequence along the return conveyor line. A horizontally rotating turntable 50 is provided at the end of the return conveyor line, and two assembly units are arranged in sequence along the turntable 50.

It can accurately capture the distribution status of all parts on the robot and the discharge hopper and tray below it. The entire action process of the robot includes the angle direction of picking up parts and the position and direction of the assembly parts on the part carrier extending to the return conveyor line. An oscillator 33 is provided at the bottom of the discharge hopper 31 and the tray 32. The oscillator 33 is used to vibrate and disperse the stacked parts on the discharge hopper 31 and the tray 32. The inclined discharge surface of the discharge hopper can make the parts stacked on the discharge hopper fall into the tray with the help of their own gravity and the vibration force of the oscillator, and under the combined action of the two forces, the stacked parts are further dispersed while falling and vibrating.

[0023] The turntable 50 is installed on the turntable mounting seat 51 of the lower low-level platform 90 beside the working platform 100 through the vertically arranged main shaft. The assembly units along the turntable 50 are arranged on the high working platform 95 beside the turntable that is higher than the working platform. The main shaft is connected to a motor and a reducer. A plurality of upper clamps 53 driven by clamp cylinders 52 for clamping the upper part of the connecting rod cylinder are evenly arranged around the turntable 50. A lower clamp 54 driven by a clamp cylinder for clamping the lower part of the connecting rod cylinder is arranged below the turntable 50 at the corresponding lower part of each upper clamp. A push-up cylinder 55 is arranged on one side below the lower clamp 54 for pushing the connecting rod cylinder upward during assembly. The lower clamp beside the turntable and the clamp cylinder driving its movement are arranged on the low-level platform 90 through a support 57. A push plate 56 is provided at the top of the push cylinder 55 next to the turntable 50 for pushing it up from the bottom of the connecting rod cylinder barrel, and the push cylinder 55 is arranged on the low-level platform 90; a camera 23 is provided above the turntable 50, and the camera is arranged on the cross bar 22 on the upper part of the column 21 vertically arranged on the low-level platform 90.

[0024] The reflux conveyor line includes an upper conveyor belt 4 and a lower conveyor belt 5 which are vertically arranged. Both the upper conveyor belt and the lower conveyor belt are driven by a motor 3. The conveying directions of the upper conveyor belt and the lower conveyor belt are opposite, so that after the part carrier is conveyed along the work flow direction of the work station on the upper conveyor belt, it can flow back to the front of the work flow direction of the work station in the opposite direction on the lower conveyor belt. The upper conveyor belt 4 and the lower conveyor belt 5 are installed on the working platform 100 through a plurality of support seats 10. Each support seat 10 includes a pair of support plates with L-shaped cross sections on both sides of the upper conveyor belt and the lower conveyor belt. The support plate is provided with a vertical portion for installing the upper conveyor belt and the lower conveyor belt and a horizontal portion connected to the working platform.

[0025] The upper conveyor belt 4 is provided with a limit plug 8 for inserting or pulling out the part carrier on both sides of each workstation, and the limit plug is connected to a transverse cylinder 7 for driving it in and out; the transverse cylinder 7 is arranged on a transversely arranged mounting seat plate 6, one end of the mounting seat plate 6 is bent and installed on the side of the upper conveyor belt 4, the limit plug 8 is provided with a bent end bent downward, and the bent end is connected to the power output end of the transverse cylinder 7, the middle of the part carrier 11 is provided with a groove for positioning and placing parts, and slots for inserting the limit plug 8 are provided on both sides of the part carrier, and a laser sensor 9 for detecting whether the part carrier is in place is provided next to each limit plug 8. After the part carrier is in place on the upper conveyor belt, the power transmission end of the transverse cylinder on both sides of the upper conveyor belt drives the limit plug to be inserted into the slots on both sides of the part carrier, so that the part carrier no longer moves. After the robot completes the assembly of the parts, the transverse cylinder drives the limit plug to be pulled out from the slot of the part carrier, and the part carrier continues on the upper conveyor belt.

[0026] Both ends of the upper conveyor belt 4 and the lower conveyor belt 5 are provided with a lifting plate 2 for lifting the part carrier 11, a lifting cylinder 1 is provided at the bottom of the lifting plate 2, and a pushing cylinder 12 for pushing the part carrier 11 into the upper conveyor belt and the lower conveyor belt is provided next to the lifting plate 2. After the part carrier 11 is transported along the work flow direction of the workstation on the upper conveyor belt, the staff can take the assembled part components on the part carrier on the upper conveyor belt, and the empty part carrier is squeezed out by the conveying force of the upper conveyor belt 4 onto the lifting plate 2 at the rear end of the conveyor belt. The lifting cylinder under the lifting plate descends until the lifting plate 2 is level with the conveying surface of the lower conveyor belt 5, and the empty part carrier is pushed into the lower conveyor belt by the pushing cylinder 12, or the staff can manually push the part carrier into The lower conveyor belt is used to better adjust and control the assembly progress. The lifting cylinder drives the lifting pallet to rise to the level of the upper conveyor belt. The empty part carrier on the lower conveyor belt flows back to the front of the work flow direction of the workstation in the opposite direction, that is, the front end of the lower conveyor belt. The empty part carrier is squeezed out by the conveying force of the lower conveyor belt onto the lifting pallet at the front end of the conveyor belt. At this time, the lifting pallet is level with the conveying surface of the lower conveyor belt. After that, the lifting cylinder at the front end drives the lifting pallet together with the empty part carrier to rise to the level of the conveying surface of the upper conveyor belt. The pushing cylinder pushes the empty part carrier into the upper conveyor belt. The empty part carrier circulates on the three workstations on the upper conveyor belt, and the lifting cylinder at the front end drives the lifting pallet to descend and return to its position. In this way, the part carrier rotates back and forth on the upper and lower conveyor belts.

[0027] The robot 40, the camera 23, the oscillator 33, the driving motor 2 of the upper conveyor belt 4 and the lower conveyor belt 5, the lifting cylinder 1, the laser sensor 9, the push cylinder 55, the clamp cylinder 52, and the motor driving the horizontal rotation of the turntable 50 are all connected to a control unit, and the control unit is connected to a data analysis unit. The data analysis unit collects and analyzes the data captured by the camera, accurately determines the state of the parts distribution, the state of the position, the state and position of the robot picker, so as to accurately assemble. The control unit is connected to the control screen.

[0028] The reflow conveyor line has three stations, and each robot can be equipped with one material picker or multiple material pickers. The multiple material pickers can all be clamps 41 with different shapes and specifications, or magnetic suckers 42 with different shapes and diameters. One robot can also be equipped with clamps 41 and magnetic suckers 42 at the same time. For example, the robot at the first station has five material pickers with different shapes and specifications of magnetic suckers 42 to pick up parts with different diameters; the robot at the second station has a material picker with a magnetic sucker 42. The robot at the third station has multiple material pickers, including magnetic suckers 42 and clamps 41; the clamps 41 can clamp parts from the outside or open from the inside of the part to clamp parts. There is a material tray with multiple slots 34-1 on the first and third stations of the reflux conveyor line. It is a multi-slot material tray 34, and a part is placed in each slot. There is no discharge hopper next to the multi-slot material tray 34. An oscillator 33 can also be provided at the bottom of the multi-slot material tray 34 to vibrate the parts that are not manually placed flat in the slot into place.

[0029] The turntable 50 has four workstations, and two assembly units are arranged next to the four workstations. Two multi-slot trays 34 are arranged next to the robot of each assembly unit. A part is placed on each multi-slot tray 34. Each robot can be equipped with one material picker or multiple material pickers. The multiple material pickers can all be clamps 41 of different shapes and specifications, or magnetic suction cups 42 of different shapes and diameters. A robot can also be equipped with clamps 41 and magnetic suction cups 42 at the same time to pick up multi-slot trays 34 of different shapes and sizes or parts in trays 32; the clamp 41 can clamp the parts from the outside, or it can open and clamp the parts from the inside of the part. Upper and lower clamps driven by clamp cylinders are set on each workstation of the turntable to clamp the upper and lower parts of the connecting rod cylinder. The turntable rotates horizontally to enable each workstation to flow between the two assembly units. The two robots nearby automatically clamp the parts and assemble them on the connecting rod cylinder of the corresponding workstation in sequence according to the process requirements, and the assembly process is automatically completed. Finally, when the assembled connecting rod assembly is driven by the turntable back to the first workstation of the set turntable, it can be taken out by the staff and another connecting rod cylinder to be assembled can be placed on it. The staff can also assemble the first part on the connecting rod cylinder at the same time.

[0030] The assembly method includes: when in use, the staff only needs to place a certain number of parts in the discharge hoppers of all workstations in turn according to the assembly process, make corresponding settings on the control screen, and the control program in the control unit will control it according to various parameters.

[0031] The reflux conveyor line is started, and the part carrier flows on the three stations of the upper conveyor belt and the lower conveyor belt. When the laser sensor on the first station senses the part carrier, the camera on the first station captures the scattered state of parts in the tray or the stable state of parts placement, and controls the clamp of the robot at the first station to pick up a single independent and scattered part in the tray of the first station, rotate horizontally to a certain direction and put it into the groove of the empty part carrier. The clamp is released and rises, and the robot at the first station returns to the tray to continue picking up another part and continue to assemble it on the part carrier of the first station with two parts. The part carrier with two parts flows to the second station, and at the same time, another empty part carrier is transported to the first station by the upper conveyor belt; when the laser sensor on the second station senses the part carrier, the camera on the second station captures the scattered state of parts in the tray or the stable state of parts placement, and controls the magnetic suction head of the robot at the second station to suck the single independent and scattered part in the tray of the second station. The independent and scattered single parts or the stable and placed single parts are assembled into the parts carrier, the magnetic suction head is disconnected and the electromagnetic release rises, the robot at the second station returns to the tray to continue to pick up another part for assembly, and the parts carrier continues to flow to the third station. While assembling at the second station, the empty parts carrier at the first station continues to load parts; similarly, when the laser sensor at the third station senses the parts carrier, the camera at the third station shoots the scattered state of the parts in the tray or the stable state of the parts, and controls the robot at the third station to pick up the independent and scattered single parts or the stable and placed single parts in the tray for assembly, and then the rotary picker uses the magnetic suction head to absorb another part for assembly, and the assembly with the above multiple parts moves to the rear end with the parts carrier on the upper conveyor belt, the staff takes out the assembly, and the empty parts carrier is lowered to the lower conveyor belt through the lifting plate and the lifting cylinder, and is transported back to the front end of the conveyor belt by the lower conveyor belt. The reflux conveyor line and assembly unit on the working platform repeatedly and automatically assemble components. The assembly units of multiple stations can be assembled at the same time for rolling production.

[0032] The four stations of the turntable can be set up with the station on the side of the low-level platform close to the edge of the whole machine as the first station. The staff clamps the connecting rod cylinder to be assembled on the upper and lower clamps of this station, and can also assemble the first part on the connecting rod cylinder, which can be the components assembled on the return conveyor line. After the camera on the turntable captures that the assembly work of the four stations has been completed, the turntable is rotated to the second station. The camera of this station captures the scattered state of parts in the tray or the stable state of parts placement, and controls the robot of this station to pick up independent parts in the tray. The connecting rod cylinder is assembled with scattered single parts or single parts placed steadily. When assembling the parts that need to be pressed, the upward cylinder pushes the connecting rod cylinder from the bottom so that the parts that need to be pressed can be pressed together. The robot returns to the tray to continue to pick up another part for assembly. When the robot at the second station is assembling, the first station has assembled a new connecting rod assembly for the staff to take down and then install a new connecting rod cylinder to be assembled. In this way, the four stations of the turntable continue to rotate, and the assembly unit continues to assemble parts to realize the automatic assembly of the connecting rod assembly. The assembly units at multiple stations can be assembled at the same time for rolling production.

[0033] The return conveyor line and turntable can be assembled at the same time, rolling production to speed up assembly efficiency.

[0034] This shock absorber connecting rod assembly assembly method takes intelligence as its core and integrates advanced video monitoring technology, sensor technology, automatic control technology and data analysis technology. The production line can sense various parameters in the production process, such as pressure, speed, position, angle, etc. in real time, and automatically adjust according to the preset program to ensure the stability and high quality of production. At the same time, through big data analysis, the production line can continuously optimize the production process, improve production efficiency and reduce production costs. It can not only improve the core competitiveness of enterprises, increase market share and achieve sustainable development.
