Description

Technical Field

[0001] The present invention relates to the field of production of red copper sheet metal parts, and in particular to a rotary automatic riveting machine for red copper sheet metal parts. Background Art

[0002] Figure 1 There is a red copper sheet metal part 20, which includes a sheet metal part body 1 and PIN pins 2 located on both sides of the sheet metal part body 1. The PIN pins 2 are fixed on the sheet metal part body 1 by riveting. Among them, a bending part 11 is provided at the position where the sheet metal part body 1 contacts the PIN pins 2. A rivet 13 is arranged on the bending part 11 to provide positioning for the PIN pins 2. The included angle between the bending part 11 and the central area 12 of the sheet metal part body 1 is at least 5°. When assembling the PIN pins 2, it is necessary to adjust the angle of the sheet metal part body 1 so that the bending part 11 faces the riveting head and the bending part 11 is parallel to the horizontal ground, and then the riveting head presses the rivet 13 to deform its end to press the PIN pins 2, thereby riveting the PIN pins 2 to the sheet metal part body 1.

[0003] As Figure 2 shown, there are two bending parts 11 on the sheet metal part body 1, and the bending directions of the two bending parts 11 are opposite. Therefore, it is necessary to provide two sets of corresponding positioning fixtures to clamp the sheet metal part body 1, and the PIN pins 2 can be assembled only by transporting it between the two sets of fixtures by a manipulator.

[0004] In the above PIN pin 2 assembly process, it is necessary to provide two sets of clamping fixtures and a special handling manipulator. Only one side of the PIN pins 2 can be assembled at a single station. That is, at least 2 riveting stations are required to complete the PIN pin assembly task. The manipulator is actually doing useless work when returning to the previous fixture to transport the semi-finished product, and this leads to a longer riveting process, which is not conducive to mass production.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Please refer to Figure 3 , the present invention provides a rotary automatic riveting machine 10 for copper sheet metal parts, which includes: a riveting assembly 100, a PIN needle feeding assembly 200, a sheet metal part body feeding assembly 300, a blanking manipulator 400, a central turntable 500 and a plurality of loading fixtures 600 located on the central turntable 500.

[0037] The central turntable 500 is used to drive the material-carrying fixture 600 to sequentially pass through the sheet metal body loading component 300, the PIN needle loading component 200, the riveting component 100, and the unloading manipulator 400; multiple material-carrying fixtures 600 are arranged in a circular array centered on the central turntable 500. Therefore, each material-carrying fixture 600 can sequentially enter the above positions under the drive of the central turntable 500 to receive the sheet metal body 1, the PIN needle 2, and perform riveting and unloading.

[0038] The sheet metal body loading component 300 is responsible for performing the loading task of the sheet metal body 1 and is used to clamp the sheet metal body 1 on the material-carrying fixture 600; the PIN needle loading component 200 is responsible for performing the loading task of the PIN needle 2 and is used to place the PIN needle 2 on the bent portion 11 of the sheet metal body 1; the unloading manipulator 400 is responsible for performing the unloading task and is used to take away the sheet metal body 1 on the material-carrying fixture 600.

[0039] Please refer to Figure 4 , the riveting component 100 is provided with two riveting heads 110. The riveting heads 110 are used to press the position where the PIN needle 2 is connected to the sheet metal body 1 (i.e., the rivet 13) so that the PIN needle 2 is riveted to the sheet metal body 1. The two riveting heads 110 configured on the riveting component 100 are respectively aligned with the two bent portions 11 on the sheet metal body 1, and the two riveting heads 110 are independent of each other and can complete the riveting action independently. A single riveting component 100 can complete the riveting operations on the two bent portions 11, reducing the volume of the equipment and improving the riveting efficiency.

[0040] The above turntable type automatic riveting machine 10 for copper sheet metal has the following beneficial effects:

[0041] 1. Using the cooperation of the central turntable 500 and the material-carrying fixture 600 to sequentially transfer the sheet metal body and the PIN needle to each working station is beneficial to reducing the volume of the equipment and improving the space utilization rate;

[0042] 2. Two riveting heads 110 are configured in the riveting component 100 to complete the riveting operations of 2 PIN needles in one working station, reducing the riveting process and improving the riveting efficiency.

[0043] Please refer to Figure 1 and Figure 2, It should be noted that in the copper sheet metal part 20 that needs to perform riveting operations in this application, the PIN pins 2 are fixed to the two bent parts 11 by rivets 13. The bending directions of the two bent parts 11 on the sheet metal part body 1 are opposite, which also causes the axis lines of the rivets 13 located on the bent parts 11 to be unable to align with the riveting head 110. When the riveting head 110 presses down, the rivets 13 are unevenly stressed, and are easily directly broken or the extruded parts extend in the inclined direction of the bent part 11. The deformed parts of the rivets 13 cannot completely cover the hole positions on the PIN pins 2, resulting in insecure riveting; therefore, to ensure the riveting accuracy, the axis line of the rivet 13 should be aligned with the axis of the riveting head 110. Therefore, it is necessary to adjust the placement angle of the sheet metal part body 1 when performing the riveting action. For example, two corresponding loading fixtures 600 are set. When riveting, the rivets 13 on one of the bent parts 11 are aligned with the riveting head 110. After the riveting action is completed, the sheet metal part body 1 is transferred to another set of loading fixtures 600 by a manipulator, and then another riveting action is performed; although this riveting method can ensure the riveting accuracy, it requires two sets of loading fixtures 600 and a dedicated handling manipulator, which will make the equipment bulky; on the other hand, during the riveting process, it is necessary to use a handling manipulator to move the sheet metal part body 1 to change the orientation of the bent part 11, which also results in a longer riveting process.

[0044] Please refer to Figure 4 and Figure 5 , To solve the above problems, an angle adjustment mechanism 700 is provided between the central turntable 500 and the riveting assembly 100 to adjust the angle of the sheet metal part body 1 during the riveting process so that the rivets 13 on the bent part 11 are aligned with the riveting head 110.

[0045] Specifically, the angle adjustment mechanism 700 includes: a T-shaped carrier 710, a rotating shaft 720, a bottom plate 730, two sliders 740, two cylinders 750 and two return elastic pieces 760. An avoidance groove 510 is opened on the central turntable 500. The rotating shaft 720 is arranged on the central turntable 500. The T-shaped carrier 710 is rotatably arranged on the rotating shaft 720. The loading fixture 600 is arranged on the T-shaped carrier 710. The return elastic pieces 760 are arranged on the central turntable 500. The two return elastic pieces 760 are located on both sides of the rotating shaft 720. Both of the two return elastic pieces 760 are in contact with the surface of the T-shaped carrier 710 to keep the T-shaped carrier 710 balanced; optionally, the length of the T-shaped carrier 710 is greater than the length of the loading fixture 600, and the return elastic pieces 760 are in contact with the parts of the T-shaped carrier 710 that are not covered by the loading fixture 600.

[0046] The two reset elastic pieces 760 are located on both sides of the T-shaped carrier 710. When the T-shaped carrier 710 rotates around the rotating shaft 720, one side of the T-shaped carrier 710 will sink and the other side will rise. The sinking side will separate from the reset elastic piece 760, while the rising side will push against the reset elastic piece 760, causing the reset elastic piece 760 to bend. After removing the external force that drives the T-shaped carrier 710 to rotate, the bent reset elastic piece 760 will provide an elastic force to make the T-shaped carrier 710 swing in the opposite direction and restore it to a state parallel to the horizontal ground. The two reset elastic pieces 760 cooperate to provide an elastic force to enable the T-shaped carrier 710 to restore balance after yawing.

[0047] The bottom plate 730 is arranged on the riveting assembly 100. The bottom plate 730 extends below the central turntable 500. Two sliders 740 are arranged on the bottom plate 730 at intervals. Two air cylinders 750 cooperate to push the two sliders 740 to alternately displace below the T-shaped carrier 710. Part of the bottom plate 730 is exposed outside the central turntable 500, and part of it is covered by the central turntable 500. The air cylinders 750 are located at the position exposed outside the central turntable 500. When the air cylinders 750 are not activated, the sliders 740 are also restricted to the area of the bottom plate 730 that is not covered by the central turntable 500. Only when performing the riveting action, the air cylinders 750 push the sliders 740 into the area below the central turntable 500, making the sliders 740 contact the T-shaped carrier 710, thereby driving the T-shaped carrier 710 to yaw. The air cylinders 750 control the two sliders 740 to alternately enter below the T-shaped carrier 710, change the yaw direction of the T-shaped carrier 710, and then adjust the placement angle of the sheet metal part body 1 so that the rivets 13 to be riveted on it are aligned with the riveting head 110.

[0048] Please refer to Figure 6 and Figure 8 As shown in, the surface of the slider 740 is provided with an inclined surface 741. The inclination angle of the inclined surface 741 is the same as the bending angle of the bent part 11 on the sheet metal part body 1. The inclined surface 741 is used to guide the T-shaped carrier 710 to deflect around the rotating shaft 720 so that the bent part 11 on the sheet metal part body 1 is parallel to the horizontal ground.

[0049] The function of the angle adjustment mechanism 700 during the riveting process is as follows:

[0050] When the air cylinders 750 are not activated, neither of the two sliders 740 contacts the T-shaped carrier 710. The T-shaped carrier 710 is parallel to the horizontal ground under the block of the two reset elastic pieces 760. The loading fixture 600 is arranged on the T-shaped carrier 710. Therefore, the loading fixture 600 is also in a balanced state. At this time, the state of the reset elastic piece 760 and the T-shaped carrier 710 is as Figure 7 shown;

[0051] The central turntable 500 drives the material-carrying fixture 600 to sequentially pass through the sheet metal body feeding component 300 and the PIN needle feeding component 200. The sheet metal body feeding component 300 clamps the sheet metal body 1 on the material-carrying fixture 600, and the PIN needle feeding component 200 places the PIN needles 2 on the sheet metal body 1. At this time, the PIN needles 2 are temporarily fixed by the rivets 13 on the bending part 11 of the sheet metal body 1.

[0052] When the above-mentioned material-carrying fixture 600 moves to the position where the riveting component 100 is located, the angle adjustment mechanism 700 is activated. One of the sliders 740 is pushed out. This slider 740 contacts the bottom of the T-shaped carrier 710 and causes the T-shaped carrier 710 to yaw under the guidance of the inclined surface 741, so that one side of the T-shaped carrier 710 is lifted, as Figure 8 shown; at this time, one of the bending parts 11 on the sheet metal body 1 is lifted, and the rivet 13 on it is aligned with one of the riveting heads 110. This riveting head 110 presses down to deform the rivet 13. After completing the riveting task on one side, the riveting head 110 resets, and the slider 740 returns to its original position. The T-shaped carrier 710 returns to the Figure 7 balanced state shown.

[0053] Then, the other slider 740 is pushed out to drive the T-shaped carrier 710 to yaw in the same way, so that the other side of the T-shaped carrier 710 is lifted, as Figure 9 shown. At this time, the bending part 11 on the sheet metal body 1 that has not been riveted is lifted, and the rivet 13 on it is aligned with the other riveting head 110. The riveting head 110 performs the riveting operation. After the riveting is completed, the slider 740 and the riveting head 110 reset, and the T-shaped carrier 710 returns to the Figure 7 balanced state shown. At this time, the riveting of both PIN needles 2 on the sheet metal body 1 is completed, and the central turntable 500 removes the material-carrying fixture 600 carrying the sheet metal body 1.

[0054] The angle adjustment mechanism 700 has the following beneficial effects during the process of assisting the riveting component 100 in riveting:

[0055] 1. During the riveting process, the slider 740 drives the T-shaped carrier 710 to yaw, so that the rivet 13 on the bending part 11 is aligned with the riveting head 110, which can ensure the riveting accuracy; at the same time, the slider 740 is always padded at the bottom of the T-shaped carrier 710 during the riveting process to provide a limit to maintain the yaw angle of the T-shaped carrier 710 and prevent the pressure generated when the riveting head 110 presses down from causing the T-shaped carrier 710 to shift.

[0056] 2. The T-shaped stage 710 is a rotatable structure. By alternately extending two sliders 740, the T-shaped stage 710 is driven to yaw in different directions, realizing the adjustment of the angle of the sheet metal part body 1. There is no need to re-clamp the sheet metal part body 1, which is beneficial to simplifying the riveting process and improving the riveting efficiency of the PIN pins 2.

[0057] 3. Two reset elastic pieces 760 cooperate with the rotating shaft 720 to make the T-shaped stage 710 parallel to the horizontal ground, making the T-shaped stage 710 in a floating state, avoiding the pressure when the riveting head 110 presses down from directly acting on the central turntable 500, which is beneficial to improving the service life of the central turntable 500.

[0058] In one embodiment, a quenched layer is provided at the part of the T-shaped stage 710 in contact with the inclined surface 741 to improve the wear resistance of the part of the T-shaped stage 710 in contact with the slider 740.

[0059] Please refer to Figure 4 In one embodiment, a track 731 is opened on the bottom plate 730, and the slider 740 slides along the track 731. The track 731 guides the moving direction of the slider 740 and provides a limit to prevent the slider 740 from deflecting laterally.

[0060] Please refer to Figure 6 In one embodiment, a U-shaped buckle 742 is opened on the slider 740, and a fastening nut cooperating with the U-shaped buckle 742 is provided on the output end of the air cylinder 750. Loosening the fastening nut can release the locking of the U-shaped buckle 742, so as to facilitate the replacement of the slider 740.

[0061] Please refer to Figure 3 In one embodiment, the turntable type automatic riveting machine 10 for copper sheet metal parts further includes a control box 800, and a plurality of buttons 810 are provided on the control box 800.

[0062] Please refer to Figure 3 In one embodiment, the sheet metal part feeding assembly 300 includes a rotating loading table 310, a lifting lead screw 320 and a first feeding robot 330. Two storage areas 311 are provided on the rotating loading table 310, and a plurality of sheet metal part bodies 1 are stacked in each storage area 311. The lifting lead screw 320 is located on one side close to the central turntable 500. The lifting lead screw 320 is used to push the sheet metal part body in the storage area 311 to rise. The first feeding robot 330 reciprocates above the lifting lead screw 320 and above the central turntable 500. When the first feeding robot 330 moves above the lifting lead screw 320, it can pick up the uppermost sheet metal part body 1 on the storage area 311 and transfer the sheet metal part body 1 from the storage area 311 to the loading fixture 600 of the central turntable 500.

[0063] Please refer to Figure 3, In one embodiment, the PIN pin feeding assembly 200 includes a vibrating bowl 210, a linear motor 220 and a second feeding manipulator 230. An outlet track 211 is provided on the vibrating bowl 210, and the outlet track 211 extends towards the central turntable 500. The linear motor 220 is used to drive the second feeding manipulator 230 to translate between the outlet track 211 and the central turntable 500. Preferably, there are 2 vacuum suction cups 231 on the second feeding manipulator 230, and the vacuum suction cups 231 are used to adsorb the PIN pins 2 on the outlet track 211.

[0064] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
