Description

Technical Field

[0001] The present invention relates to the technical field of stamping manufacturing equipment, in particular to a fully automatic production line for automobile seat pipes. Background Art

[0002] Automobile seat tubes are an important component of the automobile seat frame and constitute the basic support structure of the seat. Their processing usually requires core processes such as reducing the diameter of both ends, shaping, stamping, boring the inner hole, and turning the outer diameter. Some automated processing systems are also equipped with auxiliary links such as loading and conveying, guiding, lifting and transferring by loading robots to achieve efficient and precise production.

[0003] A stamping die robot with the publication number "CN201710727207.2" in the prior art has a structure including a flexible grasping device, a connecting head, a support rod, a wrist, a forearm, an elbow, a fixed plate, an upper arm, a fixed bolt, a shoulder, a base, and a bottom plate; the flexible grasping device is composed of a non-slip grasping plate, fingers, a transmission rod, a turntable, a rotating shaft, and a fixed palm. The non-slip grasping plate is installed on the inner side of the fingers, and the fingers are connected to the rotating shaft through the transmission rod. The bottom of the rotating shaft is vertically connected to the front side of the fixed palm, the top of the fixed palm is movably connected to the bottom of the rotating shaft, and the top of the rotating shaft is fixed to the bottom of the connecting head. The device adds a flexible grasping device, which is flexible enough when grasping, and can also be rotated to pick up items, is not easy to fall, and has better fastening.

[0004] However, the above-mentioned device still has obvious defects during use: the robot arm of the above-mentioned device adopts a clamping picking form, but this picking structure is difficult to achieve normal clamping of the seat tube fittings after stamping, because the seat tube fittings usually have a smooth surface after stamping and it is difficult to find a suitable clamping position. Due to the irregular structure of the seat tube fittings after stamping, the common clamping, adsorption and other measures in the existing technology are difficult to achieve stable effects. Although there are still robot arms that use magnetic adsorption, their adsorption part is single, and it is difficult to ensure that no damage is caused to the workpiece during the adsorption process, and the transportation stability after adsorption is also difficult to ensure. In addition, the stamping picking robot arm in the existing technology is usually designed according to the structure of the formed workpiece. A set of robots is often only used for clamping one workpiece, but since the structure of automobile seat tube fittings is scattered and complex, the above-mentioned matching robot arm form requires a lot of financial and material resources. In summary, the existing robots are difficult to adapt to the diverse seat tube picking needs, and the stability of the picking process is also difficult to ensure. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-6 , the present invention provides a technical solution:

[0035] Example 1:

[0036] A fully automatic production line for automobile seat pipe fittings, comprising:

[0037] Workbench 1, a conveyor is provided at the front end of the workbench 1, and the workpiece to be processed is conveyed to the rear end of the workbench 1 through the conveyor;

[0038] The loading platform 2 is arranged on both sides of the front end of the workbench 1, and is used for stacking, clamping and positioning the workpieces to be processed;

[0039] The first truss manipulator 3 is used to absorb and transfer the workpieces to be processed stacked in the loading tables 2 on both sides and place them on the conveying table;

[0040] The stamping device includes an upper die 4 and a lower die 5. The lower die 5 is fixedly mounted on the workbench 1 at the rear end of the conveyor. The upper die 4 is lifted above the lower die 5. The workpiece is punched and formed by the lifting movement of the upper die 4.

[0041] The second truss manipulator 6 is used to absorb and transfer the workpiece to be processed on the transfer table and place it on the lower mold 5 of the stamping device; and

[0042] The forming and taking-up manipulator 7 is arranged on the workbench 1 at the rear end of the punching device in a fixed-axis rotating manner. The forming and taking-up manipulator 7 includes a telescopic arm 8 and a manipulator part. The telescopic movement of the telescopic arm 8 drives the manipulator part to move synchronously.

[0043] The manipulator includes a lifting frame 9, a lifting block 10, a translation slide 11, a sliding sleeve frame 12 and an adsorption and fixing component. The lifting frame 9 is fixedly installed on the telescopic arm 8, the lifting block 10 is installed on the lifting frame 9 in a lifting manner, the translation slide 11 is fixedly installed on the side of the lifting block 10 away from the telescopic arm 8, the sliding sleeve frame 12 is translationally slidably sleeved on the translation slide 11, and the adsorption and fixing component is fixedly rotatably installed at the bottom of the sliding sleeve frame 12, wherein the adsorption and fixing component includes a number of equidistant linearly arranged electromagnetic adsorption rods 13, which are used to adsorb the stamped workpiece and suspend the mold resin after power is turned on. A hollow liquid spray channel 14 is provided inside the electromagnetic adsorption rod 13, and the cooling liquid is released outward through the hollow liquid spray channel 14.

[0044] In this embodiment, the workbench 1 is used to carry various parts, and a conveying platform is provided at the front end thereof for automatic conveying of workpieces to be processed. The workpieces to be processed are stacked on the loading platform 2, and the first truss manipulator 3 completes the transfer operation of the workpieces to be processed from the loading platform 2 to the conveying platform. The workpieces to be processed are transported to the side close to the stamping device through the conveying platform. At this time, the workpieces to be processed are clamped from one side of the conveying platform by the second truss manipulator 6 and placed on the lower mold 5 of the stamping device. The mold closing and stamping operation is performed by the lifting movement of the upper mold 4, and the workpiece formed on the lower mold 5 is taken out by the forming removal manipulator 7 after the stamping is completed. The main difference from the prior art is that the forming removal manipulator 7 in this application has The special mechanical structure is mainly reflected in the position of the manipulator, wherein the manipulator includes a lifting frame 9, a lifting block 10, a translation slide rod 11, a sliding sleeve frame 12 and an adsorption and fixing component. The adsorption and fixing component includes a number of electromagnetic adsorption rods 13 arranged equidistantly and linearly. The electromagnetic adsorption rods 13 generate magnetic adsorption force during the power-on process. Since the forming and picking robot 7 is mainly used for stamping operations of steel parts, the magnetic force generated by the electromagnetic adsorption rods 13 can adsorb the workpiece after stamping. However, in order to ensure stability during adsorption and transportation, the manipulator in this embodiment is not only composed of the electromagnetic adsorption rods 13, but also includes a bonding body formed by curing and molding of the reverse mold resin. The specific production process of the bonding body is as follows, refer to the attached manual. Figure 3When the upper mold 5 moves downward to stamp the workpiece, the lower mold 5 is usually set to a concave surface, so a downward groove will be formed on the workpiece at this time. At this time, the molten resin is introduced into the workpiece, and the bottom ends of several electromagnetic adsorption rods 13 are inserted into the molten resin, and the bottom ends are against the surface of the workpiece. After the resin is solidified, the solidified resin and the inverted workpiece are removed, and the workpiece is further removed from the inverted resin to form a fitting body. The significance of this design is that the fitting body is made by inverting the mold, so it can fit tightly with the surface of the stamped workpiece, and combined with the magnetic force generated by the electromagnetic adsorption rod 13, the formed workpiece can be smoothly adsorbed, and the damage to the workpiece can be reduced during the adsorption process, and it can also It can ensure stability during the transportation process. In addition, the mold resin can be repeatedly melted and molded, so that it can be made into a fitting body that meets the needs of different molded workpieces, and then a set of molding and picking robots 7 can be used to meet the clamping and transportation needs of multiple groups of automobile seat pipes. Since the melting point of the hot-melt resin used in this application is about 200 degrees Celsius, and the surface temperature of the stamping device will be close to the melting point of the mold resin when performing repeated cold stamping molding, in order to prevent the resin material from softening, it is necessary to cool it before clamping the molded workpiece. For this purpose, a hollow liquid spray channel 14 is provided inside the electromagnetic adsorption rod 13, and the cooling liquid is released outward through the hollow liquid spray channel 14, thereby ensuring that the molded workpiece will not cause the mold resin to soften during the clamping process.

[0045] Example 2:

[0046] The adsorption and fixing assembly also includes a connecting frame 15, which is movably installed at the bottom of the sliding frame 12. Several electromagnetic adsorption rods 13 are installed in a lifting groove opened in the connecting frame 15. A traction spring 16 is provided between the electromagnetic adsorption rod 13 and the connecting frame 15. The traction spring 16 is used to push the electromagnetic adsorption rod 13 downward when there is no external force. Several electromagnetic adsorption rods 13 are connected to the magnetic control circuit through wires.

[0047] In this embodiment, the structure of the adsorption fixing component is further disclosed. A plurality of electromagnetic adsorption rods 13 are installed through a connecting frame 15. A traction spring 16 is provided between the electromagnetic adsorption rod 13 and the connecting frame 15. The traction spring 16 can ensure that the electromagnetic adsorption rod 13 is at the lowest limit position without external force. The significance of such a setting is that, since the heights of various positions of the workpiece are not consistent, it is necessary to drive the connecting frame 15 downward during the solidification molding process of the molten resin so that the bottom ends of the plurality of electromagnetic adsorption rods 13 are immersed in the molten resin liquid. Therefore, the traction spring is provided. The arrangement can ensure that the bottom ends of several electromagnetic adsorption rods 13 are all against the surface of the workpiece. After the mold resin is solidified, the solidified mold resin makes the electromagnetic adsorption rod 13 maintain this abutment state. It should be noted that since the bottom of the electromagnetic adsorption rod 13 serves as the outlet of the cooling liquid, after the mold is completed, if the solidified resin enters the hollow liquid spray channel 14 and solidifies to block the channel, it is necessary to clear the inside of the hollow liquid spray channel 14 through the heated rod body to ensure the smooth flow of the hollow liquid spray channel 14. When repeated molding is required, the solidified mold resin needs to be melted and molded for the next time.

[0048] Example 3:

[0049] A blanking workbench 31 is also provided on the side of the workbench 1 close to the molding and picking robot 7. A resin melting tank 17 and a molding workpiece placement tank 18 are provided on the blanking workbench 31. The resin melting tank 17 is surrounded by melting heating wires, and the mold resin suspended on the electromagnetic adsorption rod 13 is melted by the melting heating wires. The melted resin is manually transferred to the workpiece stamped by the lower mold 5, and the electromagnetic adsorption rod 13 is inserted before the resin solidifies, so that a mold resin matching the shape of the stamping mold is formed after the resin solidifies.

[0050] In this embodiment, a resin melting tank 17 is provided on the unloading workbench 31. When re-molding is required, the molding resin suspended from the bottom of the electromagnetic adsorption rod 13 is inserted into the resin melting tank 17. At this time, the molding resin is melted by the internally arranged melting heating wire. At this time, the staff can perform re-molding by pouring the melted resin into the molding workpiece groove on the lower mold 5. It should be noted that the relevant structure of the robot arm needs to ensure that it can work normally when heated to 300°C. Since a hose is connected to the top of the electromagnetic adsorption rod 13, it cannot withstand the high temperature required for the molten resin. Therefore, during the molding process, the hose needs to be unplugged from the upper end of the electromagnetic adsorption rod 13 and reconnected after the molding is completed, so as to smoothly perform the cooling and spraying operation.

[0051] Example 4:

[0052] The liquid outlet end of the hollow liquid spray channel 14 is arranged at the bottom end of the electromagnetic adsorption rod 13. The upper end of the electromagnetic adsorption rod 13 is provided with a liquid inlet hole 19. The liquid inlet hole 19 is connected to the water pump through a hose. The cooling water is sprayed through the hollow liquid spray channel 14 to the surface of the workpiece and the lower mold 5 by the water pump, thereby cooling the formed workpiece and the stamping device.

[0053] In this embodiment, a pumping device for the cooling liquid in the hollow spray channel 14 is further disclosed. The cooling liquid is pumped into the hollow spray channel 14 through a hose by a water pump and pumped out downward. The water pump can be set on a rotating seat or on a workbench 1. It is necessary to ensure that the reserved hose length does not interfere with the normal operation of the forming and picking robot 7. Since the water pump mechanism adopts a mature technical solution in the existing technology, it will not be described here.

[0054] Embodiment 5:

[0055] The forming and picking robot 7 also includes a rotating seat 20, a telescopic arm slide 21 and a telescopic drive cylinder 22. The telescopic arm slide 21 is fixedly mounted on the rotating seat 20, and the telescopic arm 8 is telescopically and slidably mounted in the clamping groove opened on the telescopic arm slide 21. The telescopic drive cylinder 22 is fixedly mounted on the telescopic arm slide 21, and its driving arm is fixedly connected to the telescopic arm 8, so that the telescopic arm 8 is driven to slide horizontally through the telescopic movement of the telescopic drive cylinder 22. The robot part is fixedly mounted on one end of the telescopic arm 8, and the rotating seat 20 performs a fixed-axis rotation motion driven by a rotary reduction motor arranged inside the workbench 1.

[0056] The mechanism that drives the lifting block 10 to translate and slide in the lifting frame 9 is the lifting screw 23. A screw hole that cooperates with the lifting screw 23 is provided on the lifting block 10. A micro reduction motor that drives the fixed-axis rotation of the lifting screw 23 is fixedly installed on the lifting frame 9. The rotational motion of the micro reduction motor drives the lifting screw 23 to perform reciprocating rotational motion, thereby driving the lifting block 10 to perform lifting motion.

[0057] In this embodiment, the specific structure and assembly method of the forming and picking robot 7 are further disclosed, wherein the mechanism for the translational motion of the telescopic arm 8 and the lifting block 10 is further disclosed. Since this structure is widely used in the prior art, it is unnecessary to elaborate on it here. Of course, other translational motion mechanisms summarized in the prior art can also be used as a substitute, which also does not exceed the scope of protection of the present invention.

[0058] Example 6:

[0059] A stop-limit knob 24 is threadedly installed on one side of the sliding sleeve frame 12 and the connecting frame 15. The stop-limit knob 24 on the sliding sleeve frame 12 can be movably pressed against the translation slide rod 11, and the stop-limit knob 24 on the connecting frame 15 can be movably pressed against the sliding sleeve frame 12, so that the positions of the sliding sleeve frame 12 and the connecting frame 15 can be adjusted by loosening or tightening the stop-limit knob 24.

[0060] In this embodiment, the position of the sliding frame 12 and the deflection angle of the connecting frame 15 need to be adjusted manually. Therefore, when the mold adjustment is required, the abutment limit knob 24 needs to be rotated to make the sliding frame 12 or the connecting frame 15 active, and the abutment limit knob 24 can be tightened after the adjustment is completed.

[0061] Embodiment seven:

The workpiece grease cleaning platform 27 is used to degrease the surface of the workpiece to be processed, thereby ensuring the stability of the workpiece to be processed during the stamping process. At the same time, the first truss manipulator 3 and the second truss manipulator 6 both use negative pressure suction cups to clamp the workpiece. Since the workpiece before stamping is mostly a flat structure, this adsorption method can effectively transfer it. The first truss manipulator 3 and the second truss manipulator 6 adopt mature technical solutions in the existing technology, and the truss-type moving parts have been fully disclosed in the existing technology and will not be repeated here.
