Description

Technical Field

[0001] This invention relates to the field of automatic feeding production line technology, and specifically to an automatic feeding production line for automotive seat foam parts. Background Technology

[0002] In the prior art, in order to improve the comfort of driving, car seats are usually filled with foam material to make them soft and comfortable. Therefore, in the production process, the corresponding parts need to be placed at the predetermined positions in the mold of the car seat first, then the foam material is filled into the mold, and finally the mold is heated to make the foam material in the mold expand and form, and can be fixed with the parts to achieve the integral molding of the seat and the parts.

[0003] Traditional car seat manufacturing processes require manual placement of components into molds. These molds need to be preheated, increasing the risk of burns to workers during component placement. Furthermore, the foaming material releases harmful gases during heating, posing a hazard to workers in the production environment.

[0004] To address the aforementioned problems, Chinese invention patent application (patent number: CN202111004743.2) discloses an automatic assembly device for automotive seat foam components and its manufacturing process. The device includes a conveyor belt for transporting seat foam molds, a vibratory feeder on one side of the conveyor belt for outputting butterfly buckles, and a robotic arm next to the vibratory feeder for gripping the output butterfly buckles. The mold has grooves for embedding butterfly buckles. A vision camera on the conveyor belt, located in front of the vibratory feeder and the robotic arm, is used to identify the type of seat foam mold. This invention utilizes the vision camera to collect mold data and feed it back to the robotic arm for gripping butterfly buckles, thereby achieving automatic feeding of pre-set butterfly buckles for automotive seat foam components, significantly improving work efficiency.

[0005] However, the equipment still has the following defects: the robot arm of the equipment is a fixed structure, and the conveyor belt used to transport the mold needs to stop at the position of the robot arm and wait for the robot arm to finish placing the mold before starting the conveyor belt to transport the mold and replace the next mold at the unloading station of the robot arm. This working method requires continuous control of the start or stop of the conveyor belt, and its working process is not continuous and its work efficiency is low. Summary of the Invention

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0023] like Figure 1-15An automated feeding production line for automotive seat foam components is shown, comprising: a base 1, a first slide rail 11, a second slide rail 12, a rack 13, and several feeding robots 2; the first slide rail 11, the second slide rail 12, and the rack 13 are all fixedly connected to the base 1; each of the feeding robots 2 has a first guide wheel assembly 21 on its side, and each of the first guide wheel assemblies 21 is slidably connected to the first slide rail 11; each of the feeding robots 2 has a second guide wheel assembly 519 slidably connected to the second slide rail 12 on its bottom surface; each of the feeding robots 2 also has a drive assembly inside, the drive end of which extends to the bottom surface of the feeding robot 2; and a gear 24 is fixedly mounted on the drive end of the drive assembly, the gear 24 meshing with the rack 13.

[0024] In this application, a gear 24 is provided on the bottom surface of the unloading robot 2, and a rack 13 that meshes with the gear 24 is provided on the base 1. Under the driving action of the drive component, the gear 24 moves along the rack 13, which can drive the robot to move. The bottom of the unloading robot 2 is also provided with universal wheels 29 for supporting the movement of the unloading robot 2. The first guide wheel assembly 21 cooperates with the first slide rail 11 to restrict the movement trajectory of the unloading robot 2, so that the unloading robot 2 can move along the preset circular track, and also ensure that the gear 24 and the rack 13 mesh with each other. The second slide rail 12 cooperates with the second guide wheel 519 assembly to make the movement of the robot more stable during the actual processing and prevent the unloading robot 2 from deviating.

[0025] In summary, this application proposes an automatic feeding production line for automotive seat foam parts, which enables the feeding robot 2 to move cyclically along a preset slide rail. When it moves to the position of the second slide rail 12, the feeding robot 2 can move together with the mold on the conveyor belt, so that the mold conveyor belt can continue to move forward while completing the purpose of feeding the part into the mold. Compared with existing feeding production line equipment, this can effectively improve the efficiency of placing foam parts in the mold.

[0026] Furthermore, such as Figure 6 , 7As shown in Figure 8; the material feeding robot 2 includes: a fixed base 25; two vibratory feeders 26 are fixedly mounted on the fixed base 25; each of the two vibratory feeders 26 is equipped with two parallel linear feeders; a robotic arm 28 is also mounted on the fixed base 25; the robotic arm 28 includes: a first robotic arm 281, a second robotic arm 282, a third robotic arm 283, a fourth robotic arm 284, a fifth robotic arm 285, and a sixth robotic arm 286; the bottom end of the first robotic arm 281 is fixedly connected to the fixed base 25; the first robotic arm 281... The top end is rotatably connected to one end of the second robotic arm 282; the other end of the second robotic arm 282 is rotatably connected to one end of the third robotic arm 283; the other end of the third robotic arm 283 is rotatably connected to one end of the fourth robotic arm 284; the other end of the fourth robotic arm 284 is rotatably connected to the fifth robotic arm 285; the other end of the fifth robotic arm 285 is rotatably connected to one end of the sixth robotic arm 286; two first cylinders 287 are fixedly installed on the sixth robotic arm 286; a vacuum suction cup 288 is respectively installed on the driving end of the two first cylinders 287.

[0027] Specifically, in this application, there are 7 material feeding robots 2, such as... Figure 1 As shown, the material feeding robot 2 on the right-hand straight track is in working condition. Up to four robots can work simultaneously. The robots in this position move synchronously and side-by-side with the conveyor belt used to transfer the foaming mold. The robots in other positions are in a completed work state. These robots circle back from the left side of the circular track to the starting position of the right-hand workstation. Because the non-working track is relatively long, the robots need to accelerate after completing their work to reach the starting position of the workstation in a timely manner, and then reduce their speed to match the speed of the other material feeding robots 2. Each material feeding robot 2 has an identical structure. The robotic arm 28 on the material feeding robot 2 picks up the material from the vibratory feeder 26 and places it into the mold. Vacuum suction cups 288 can adsorb the material being fed; two vacuum suction cups 288 can adsorb two material feeding parts simultaneously, further improving feeding efficiency.

[0028] Furthermore, such as Figure 2 As shown; the first slide rail 11 is oval in shape; the first guide wheel 213 assembly includes: a lifting control unit 211, a fixing plate 212, a first guide wheel 213, and two second guide wheels 214; the lifting control unit 211 is fixedly connected to the side wall of the fixing seat 25; the fixing plate 212 is fixedly connected to the driving end of the lifting control unit 211; the first guide wheel 213 and the two second guide wheels 214 are all rotatably connected to the fixing plate 212; the first guide wheel 213 is slidably connected to the inner ring side wall of the first slide rail 11, and the two second guide wheels 214 are all slidably connected to the outer ring side wall of the first slide rail 11.

[0029] Specifically, the first guide wheel 213 and the two second guide wheels 214 clamp the first slide rail 11 from both the inner and outer sides, enabling the unloading robot 2 to move along the first slide rail 11. In this application, the lifting control unit 211 includes circular lifting slide rails on both sides and a lead screw located in the middle. Two guide rail sliders 34 that can be adapted to the circular lifting slide rails are fixedly installed on the fixing plate 212, and a lead screw slider 34 that can be adapted to the lead screw is also provided on the fixing plate 212. By rotating the lead screw, the height of the fixing plate 212 can be adjusted so that the first guide wheel 213 and the second guide wheel 214 can be adapted to the first slide rail 11.

[0030] Furthermore, such as Figure 2 As shown, the second slide rail 12 is in a straight line; the second guide wheel 519 assembly includes: two third guide wheels 221; both third guide wheels 221 are rotatably disposed on one side of the fixed base 25; both third guide wheels 221 are provided with a first limiting groove 224 that can engage with the second slide rail 12.

[0031] The second slide rail 12 is a circular slide rail, and the third guide wheel 221 has a first limiting groove 224. When the unloading robot 2 moves to the straight part, the first limiting groove 224 and the second slide rail 12 are engaged with each other, so that the unloading robot 2 can continue to move forward along the slide rail.

[0032] Furthermore, such as Figure 2 As shown, it also includes a third slide rail 14, and two fourth guide wheels 222 are rotatably mounted on the other side of the fixed base 25. The third slide rail 14 is parallel to the second slide rail 12. When the third guide wheel 221 is on the second slide rail 12, the fourth guide wheel 222 is correspondingly on the third slide rail 14, and the fourth guide wheel 222 has a limiting strip 223 that can abut against the inner side of the third slide rail 14, which can prevent the unloading robot 2 from swinging left and right. In order to enable the unloading robot 2 to move accurately onto the track, both ends of the second slide rail 12 and the third slide rail 14 have inclined portions 121. When the third guide wheel 221 contacts the second slide rail 12, the inclined portion 121 can make the second slide rail 12 engage with the first limiting groove 224.

[0033] Furthermore, such as Figure 8 As shown, the bottom of the fixed base 25 is also fixedly equipped with multiple casters 29. When the unloading robot 2 is not in working state, the movement speed of the unloading robot 2 can be increased by relying on the casters 29 to move forward. In this application, the height of the casters 29 is less than the height of the track. When the third guide wheel 221 is on the second slide rail 12 and the fourth guide wheel 222 is on the third slide rail 14, the bottom casters 29 are in a suspended state. In this way, by restricting the unloading robot 2 through the guide wheels and slide rails, the unloading robot 2 can move more stably during operation, ensuring the working accuracy of the robot arm 28.

[0034] Furthermore, such as Figure 6 , Figure 7 As shown, a second cylinder 251 is also fixedly installed on the fixed base 25; an abutment block 252 for abutting against the foaming mold is fixedly installed on the drive end of the second cylinder 251.

[0035] When the unloading robot 2 moves to the working position, the second cylinder 251 controls the abutment block 252 to extend and abut against the mold, so that the unloading robot 2 and the mold move synchronously.

[0036] Furthermore, such as Figure 9 , Figure 10 As shown, one end of the material feeding robot 2 is also provided with a collision sensing component 3 for contacting with an adjacent material feeding robot 2; the other end of the material feeding robot 2 is provided with a collision plate 4.

[0037] In this application, the collision sensing component 3 includes: a limiting seat 31 for connection with the fixed seat 25, a circular collision plate 32, a fixing block 33, a slider 34, a connecting rod 35 that can abut against the contact switch 37, a third compression spring 36, and a contact switch 37 for electrical connection with a control device; the limiting seat 31 has a second limiting groove 311 inside; the fixing block 33 is fixedly disposed inside the second limiting groove 311; the slider 34 is slidably disposed inside the second limiting groove 311; the circular collision plate 32 is fixedly connected to the slider 34; one end of the connecting rod 35 is fixedly connected to the slider 34; the fixing block 33 has a through hole; the other end of the connecting rod 35 is accommodated inside the through hole; the third compression spring 36 is sleeved on the connecting rod 35, one end of the third compression spring 36 abuts against the slider 34; the other end of the third compression spring 36 abuts against the fixing block 33; and the contact switch 37 is fixedly connected to the limiting seat 31. The limiting seat 31 also has two third limiting grooves 312 inside, which are respectively formed on two opposite inner sidewalls of the limiting seat 31. Two first limiting blocks 341 are respectively provided on both sides of the slider 34; the two first limiting blocks 341 are respectively accommodated inside the two third limiting grooves 312. Two second limiting blocks 331 are respectively provided on both sides of the fixing block 33, which are respectively accommodated inside the two third limiting grooves 312. One end of the contact switch 37 passes through the limiting seat 31 and extends into the second limiting groove 311. The top surface of the slider 34 is fixedly connected to the bottom surface of the circular collision plate 32, and the slider 34 is fixedly connected to the center of the circular collision plate 32. Three limiting blocks 313 for fixed connection with the robot are respectively provided on both sides of the limiting seat 31; each of the two third limiting blocks 313 has a screw hole 314.

[0038] The collision sensing component 3 is positioned at a corner of the robot and faces the inner ring around which the robot travels. This means that when the robot is running around the track, the distance between two robots at the inner ring corner is the shortest. If no collision occurs at this location, the robots will not collide. The collision detection device is positioned at a 45° angle at the corner of the robot, and a circular collision plate 32 extends to the outer edge of the robot. The circular collision plate 32 disperses the force of collisions with the preceding robot, forming a component force along the connecting rod 35. This allows the connecting rod 35 to slide backward against the third compression spring 36, thereby contacting the contact switch 37 at the rear. The contact switch 37 connects to the robot's control device, which then reduces the robot's running speed.

[0039] Furthermore, such as Figure 3 , Figure 7 , Figure 13 , Figure 14 As shown, a power supply slide rail 18 for supplying power to the material feeding robot 2 is also fixedly installed on the base 1; a conductive slider 6 that can be slidably connected to the power supply slide rail 18 is fixedly installed on the fixed seat 25; an air supply plate 15 is also rotatably installed on the base 1; a plurality of air supply ports are opened on the air supply plate 15; the plurality of air supply ports are connected to a plurality of material feeding robots 2 in a corresponding manner.

[0041] Specifically, the conductive slider and the conductive rail work together to enable the unloading robot to continuously obtain power through the conductive rail during rotation. This structure eliminates the need for additional wires to connect to the unloading robot, preventing wires from falling onto the rail and affecting its normal operation. It also prevents redundant wires from getting tangled with the air supply pipes, which could affect the normal operation of the cylinders on the unloading robot.

[0042] The air supply plate 15 is equipped with a rotary motor that can control the rotation of the air supply plate 15. The fixed base 25 is also fixedly equipped with a winding assembly 618 for winding up the air supply pipe, which can wind up the excess air supply pipe and prevent redundant air supply pipe from affecting the normal operation of the equipment.

[0043] Furthermore, such as Figure 2 , Figure 4 As shown, a plurality of friction plates 16 are fixedly disposed on the base 1; as Figure 8 , Figure 11 , Figure 12 As shown, several of the material feeding robots 2 are fixedly provided with a deceleration component 5 at their bottoms, which can rub against the friction plate 16 to reduce the moving speed of the material feeding robot 2.

[0044] The deceleration assembly 5 includes: an upper mounting base 501, a lower mounting base 502, a first rubber sheet 503, a second rubber sheet 504, a first adjusting assembly for adjusting the position of the first rubber sheet 503, and a second adjusting assembly for adjusting the position of the second rubber sheet 504; the top surface of the upper mounting base 501 is fixedly connected to the bottom surface of the fixed base 25; the top surface of the lower mounting base 502 is fixedly connected to the bottom surface of the upper mounting base 501; the first rubber sheet 503 and the second rubber sheet 504 are both housed inside the lower mounting base 502, and the first rubber sheet 503 and the second rubber sheet 504 are arranged opposite to each other; one end of the first adjusting assembly is fixedly connected to one side of the lower mounting base 502; the other end of the first adjusting assembly is rotatably connected to the first rubber sheet 503; one end of the second adjusting assembly is fixedly connected to the other side of the lower mounting base 502; the other end of the second adjusting assembly is rotatably connected to the second rubber sheet 504. The first adjustment assembly includes: a first nut 505, a second nut 506, a first bolt 507, a second bolt 508, a third bolt 509, a first compression spring 510, and a first baffle 511; the first nut 505 and the second nut 506 are both fixedly connected to one side of the lower mounting base 502; the first bolt 507 is threadedly connected to the first nut 505; the second bolt 508 is threadedly connected to the second nut 506; one end of the first bolt 507 and one end of the second bolt 508 both pass through the lower mounting base 502 and are rotatably connected to the first rubber sheet 503; one end of the first compression spring 510 is fixedly connected to the first rubber sheet 503; the other end of the first compression spring 510 is fixedly connected to the first baffle 511; the third bolt 509 is rotatably connected to one side of the lower mounting base 502, and one end of the third bolt 509 also passes through the lower mounting base 502 and is threadedly connected to the first baffle 511. The second adjustment assembly includes: a third nut 512, a fourth nut 513, a fourth bolt 514, a fifth bolt 515, a sixth bolt 516, a second compression spring 517, and a second baffle 518; the third nut 512 and the fourth nut 513 are both fixedly connected to the other side of the lower mounting base 502; the fourth bolt 514 is threadedly connected to the third nut 512; the fifth bolt 515 is threadedly connected to the fourth nut 513; one end of the fourth bolt 514 and one end of the fifth bolt 515 pass through the lower mounting base 502 and are rotatably connected to the second rubber sheet 504; one end of the second compression spring 517 is fixedly connected to the second rubber sheet 504; the other end of the second compression spring 517 is fixedly connected to the second baffle 518; the sixth bolt 516 is rotatably connected to one side of the lower mounting base 502, and one end of the sixth bolt 516 also passes through the lower mounting base 502 and is threadedly connected to the second baffle 518.Specifically, the first and second bolts are used to adjust the position of the first rubber sheet, while the compression spring in the middle compensates for wear on the rubber sheet. In actual use, the position of the rubber sheet is first adjusted using the bolts at both ends to ensure that the rubber sheet can rub against the friction plate with moderate friction. After a period of use, when the rubber sheet shows some wear, the third bolt is adjusted, and the compression spring is used to push the rubber sheet towards the center, further increasing the friction between the rubber sheet and the friction plate and preventing a decrease in friction due to wear.

[0045] In this application, to reduce the robot's moving speed and prevent the robot from derailing due to inertia, friction plates 16 are installed at curves. In this application, the friction plates 16 are all located at the connection between the curved track and the straight track. The friction between the rubber sheet and the friction plate 16 converts kinetic energy into heat energy, ensuring the stability of the robot's operation.

[0046] Furthermore, such as Figure 15 As shown; the side of the unloading robot 2 is also equipped with a limit switch 23; as Figure 4 , Figure 5 As shown; a positioning piece 17 that can contact the limit switch 23 is fixedly installed on the base 1.

[0047] There are two positioning plates 17, which are respectively set at both ends of the second slide rail 12 to form a switch to cooperate with the positioning plates 17 so that the robot knows whether it has entered the work station area or has left the work station area.

[0048] Furthermore, the base is also equipped with two visual recognition components 7, which are respectively located at both ends of the second slide rail to monitor the material feeding robot on the second slide rail, ensuring that the material feeding robot can work normally and avoiding errors in the operation of the material feeding robot.

[0049] In summary, this invention provides an automatic feeding production line for automotive seat foam parts, enabling the feeding robot 2 to move cyclically along a preset slide rail. When it reaches the position of the second slide rail 12, the feeding robot 2 can move together with the mold on the conveyor belt, so that the mold conveyor belt can continue to move forward while completing the purpose of feeding the foam parts into the mold. Compared with existing feeding production line equipment, this invention can effectively improve the efficiency of placing foam parts in the mold.
