Technical Field

[0001] This invention relates to the field of metal structural component welding equipment technology, and in particular to a high-speed positioning, cutting and welding integrated machine. Background Technology

[0002] Figure 1 A metal welded assembly structure is shown, comprising a first metal part 100 and a second metal part 200 welded together. Since both the first and second metal parts are relatively small structural components, they are stored and transported separately using strips. In the prior art, the production of this metal welded assembly structure requires unloading the first metal part from a first strip and transferring it to a welding platform using a first robotic arm. Then, the second metal part is unloaded from a second strip and transferred to the first metal part on the welding platform using a second robotic arm. Finally, the first and second metal parts are welded together. This entire process is cumbersome, requires bulky equipment, and, more importantly, results in low production efficiency.

[0040] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0041] Please refer to Figures 1 to 10 High-speed positioning, cutting, and welding integrated machine, including:

[0042] The frame 1 is provided with a first feed channel for conveying a first material strip and a second feed channel for conveying a second material strip. The second feed channel is located above the first feed channel. When viewed from above, the second feed channel intersects with the first feed channel. The first material strip is used to carry a first metal part 100, and the second material strip is used to carry a second metal part 200.

[0043] A drive assembly, comprising a drive motor 21 and a rotating shaft 22, wherein the rotating shaft 22 is rotatably mounted on the frame 1, and the drive motor 21 is connected to the rotating shaft 22 to drive the rotating shaft 22 to rotate.

[0044] The first conjugate cam 31 is fixed on the rotating shaft 22;

[0045] A floating support assembly 32 includes a first transmission mechanism 321 and a receiving member 322. The first transmission mechanism 321 connects the first conjugate cam 31 and the receiving member 322 to drive the receiving member 322 to rise and fall. The receiving member 322 is used to support the second metal part 200.

[0046] The second conjugate cam 41 is fixed on the rotating shaft 22;

[0047] The cutting assembly 42 includes a second transmission mechanism 421 and a cutting seat 422. The second transmission mechanism 421 connects the second conjugate cam 41 and the cutting seat 422 to drive the cutting seat 422 to rise and fall. The cutting seat 422 is provided with a cutting element 4223, which is located above the receiving member 322. The cutting element 4223 is used to cut the second metal part 200 on the second strip from top to bottom.

[0048] The third conjugate cam 51 is fixed on the rotating shaft 22;

[0049] The pressing assembly 52 includes a third transmission mechanism 521 and a pressing seat 522. The third transmission mechanism 521 connects the third conjugate cam 51 and the pressing seat 522 to drive the pressing seat 522 to rise and fall. The pressing seat 522 is provided with a pressing member 5221, which is used to press down the second metal part 200 and the first metal part 100 after they have been lowered.

[0050] Positioning cam 61, which is fixed on the rotating shaft 22;

[0051] The first positioning component 62 includes a fourth transmission mechanism 621 and a positioning seat 622. The fourth transmission mechanism 621 connects the positioning cam 61 and the positioning seat 622 to drive the positioning seat 622 to rise and fall. The positioning seat 622 is provided with a first positioning pin group. The first positioning pin group includes a plurality of first positioning posts 6221. The first positioning posts 6221 are used to position the first material strip.

[0052] A first feed assembly is used to feed the first material strip;

[0053] The second feeding assembly is used to feed the second strip;

[0054] A welding device for welding the second metal part 200 and the first metal part 100 pressed against by the lower pressure member 5221;

[0055] The drive motor 21 drives the rotating shaft 22 to rotate once, and the high-speed positioning cutting and welding integrated machine completes one cycle. In a single cycle, the welding time of the welding device is greater than or equal to the time required for the rotating shaft 22 to rotate 1 / 3 of a revolution.

[0056] As can be seen from the above description, the beneficial effects of this invention are as follows: This high-speed positioning cutting and welding integrated machine has a novel structure, which ingeniously integrates multiple workstations together and creatively utilizes cams to drive each mechanism to complete all processes. This not only simplifies the equipment structure and reduces the overall size of the equipment, but also requires only a single power source, effectively saving energy consumption. More importantly, this high-speed positioning cutting and welding integrated machine can significantly improve production efficiency and reduce production costs. Moreover, the reasonable design of the working step sequence of the high-speed positioning cutting and welding integrated machine ensures that the welding time is greater than or equal to the time required for the rotating shaft to rotate 1 / 3 revolution, thereby increasing the rotational speed of the rotating shaft and shortening the completion time of a single cycle, which is conducive to further improving the working efficiency of the high-speed positioning cutting and welding integrated machine.

[0057] Furthermore, the positioning seat 622 is also provided with a second positioning pin group, which includes a plurality of second positioning pins 6222, and the top surface of the receiving member 322 is provided with a through hole for the second positioning pins 6222 to pass through.

[0058] As described above, the second positioning pin group can accurately position the second metal part 200 received by the receiving part 322, which helps to improve the cutting accuracy and the alignment accuracy between the first metal part 100 and the second metal part 200, thereby improving the cutting quality and welding quality, and thus reducing the production defect rate.

[0059] Furthermore, the cutting element 4223 is provided with a clearance hole 4224 for avoiding the second positioning post 6222.

[0060] As can be seen from the above description, the setting of the clearance hole 4224 can avoid interference between the second positioning post 6222 and the cutting part 4223, which helps to ensure the stability of the equipment operation.

[0061] Furthermore, the cutting seat 422 is provided with a third positioning post 4221.

[0062] As described above, the third positioning post 4221 is used to position the second strip to prevent other areas of the second strip from moving unexpectedly when the cutting part 4223 cuts the second metal part 200 on the second strip, which helps to further ensure the stability of the equipment operation.

[0063] Furthermore, the third positioning post 4221 is vertically adjustable relative to the cutting seat 422, and the cutting seat 422 is provided with a cutting reset member 4222, which is used to drive the third positioning post 4221 to descend.

[0064] As can be seen from the above description, the third positioning post 4221 is floating, which can effectively improve the problem of the third positioning post 4221 damaging the second strip, and also ensure that the cut piece 4223 has sufficient descent space.

[0065] Furthermore, the pressing member 5221 is vertically and vertically arranged relative to the pressing base 522, and the pressing base 522 is provided with a pressing reset member 5222, which is used to drive the pressing member 5221 to descend.

[0066] As described above, the pressing component 5221 can press down on the area near the welding point of the second metal component 200 from top to bottom, thereby avoiding the phenomenon of incomplete welding between the first metal component 100 and the second metal component 200, which is conducive to further improving the welding quality and reducing the production defect rate.

[0067] Furthermore, the welding time of the welding device in a single cycle is the time required for the rotating shaft 22 to rotate half a turn.

[0068] As described above, the welding time required for the welding device to weld the first metal part and the second metal part is fixed. The larger the rotation angle of the rotating shaft corresponding to the welding time of the welding device, the faster the rotation speed of the rotating shaft can be. When the welding time of the welding device in a single cycle is the time required for the rotating shaft 22 to rotate half a turn, the time required for a single cycle can be minimized while ensuring that the components do not interfere with each other. In other words, the working efficiency of the high-speed positioning cutting and welding integrated machine reaches its peak.

[0069] Furthermore, in a single cycle, the working time of the first feed component and the working time of the second feed component at least partially overlap, and both are staggered from the working time of the welding device.

[0070] Furthermore, when the cutting component 4223 is reset upwards but has not yet completed the reset, the first feeding component feeds the first material strip.

[0071] Furthermore, as the cutting component 4223 descends, the pressing component 5221 also descends. In the cyclic operation, the starting time of the descent of the cutting component 4223 is earlier than the starting time of the descent of the pressing component 5221.

[0072] By setting it up as described above, the time required for a single cycle of work can be further reduced.

[0073] Example 1

[0074] Please refer to Figures 1 to 10 The first embodiment of the present invention is as follows: Please refer to... Figures 2 to 4 The high-speed positioning, cutting, and welding integrated machine includes a frame 1, a drive assembly, a first conjugate cam 31, a floating load-bearing assembly 32, a second conjugate cam 41, a cutting assembly 42, a third conjugate cam 51, a pressing assembly 52, a positioning cam 61, a first positioning assembly 62, and a welding device (not shown in the figure). The welding device is preferably a laser welding device.

[0075] The frame 1 is provided with a first feed channel for conveying a first material strip and a second feed channel for conveying a second material strip. The second feed channel is located above the first feed channel. When viewed from above, the high-speed positioning cutting and welding integrated machine intersects with the first feed channel. Figure 1 As shown, the first material strip is used to carry the first metal part 100, and the second material strip is used to carry the second metal part 200. In this embodiment, the feeding direction of the first material strip is set along the X-axis direction, and the feeding direction of the second material strip is set along the Y-axis direction. That is to say, when looking down at the high-speed positioning cutting and welding integrated machine, the first feeding channel is perpendicular to the second feeding channel.

[0076] like Figure 2 and Figure 3 As shown, optionally, the frame 1 is further provided with a first feeding assembly for feeding the first material strip and a second feeding assembly (not shown) for feeding the second material strip. Specifically, the first feeding assembly includes a feeding motor 71 and a feeding gear 72. The feeding motor 71 is fixed on the frame 1, and the output end of the feeding motor 71 is connected to the feeding gear 72. The first material strip has a feeding groove that cooperates with the feeding gear 72. The feeding motor 71 drives the feeding gear 72 to rotate, thereby driving the first material strip to move forward.

[0077] To facilitate the adjustment of the position of the frame 1 to better adapt to the installation environment, the high-speed positioning cutting and welding integrated machine may optionally include a base 8. The frame 1 is slidably mounted on the base 8. Specifically, the bottom of the frame 1 is connected to the base 8 through an X-axis sliding joint, a Y-axis sliding joint, or an XY two-axis sliding joint.

[0078] Please combine Figures 2 to 4 The drive assembly includes a drive motor 21 and a rotating shaft 22. The rotating shaft 22 is rotatably mounted on the frame 1. The drive motor 21 is connected to the rotating shaft 22 to drive the rotating shaft 22 to rotate. In a preferred embodiment, the drive motor 21 is fixed on the frame 1, and the drive motor 21 and the rotating shaft 22 are connected by a belt or gear transmission.

[0079] Please combine Figures 2 to 5 The first conjugate cam 31 is fixed on the rotating shaft 22. The floating bearing assembly 32 includes a first transmission mechanism 321 and a receiving member 322. The first transmission mechanism 321 connects the first conjugate cam 31 and the receiving member 322 to drive the receiving member 322 to rise and fall. Specifically, the first transmission mechanism 321 includes a first Y-shaped arm 3211, a first lifting arm 3212, a first swing arm 3213, and a receiving seat 3214. The first Y-shaped arm 3211 is rotatably connected to the frame 1, and the first Y-shaped arm 3211 is in transmission cooperation with the first conjugate cam 31. The end of the first Y-shaped arm 3211 away from the first conjugate cam 31 is rotatably connected to the first lifting arm 3212. The end of the first lifting arm 3212 away from the first Y-shaped arm 3211 is rotatably connected to one end of the first swing arm 3213. The middle part of the first swing arm 3213 is rotatably connected to the frame 1. The end of the first swing arm 3213 away from the first lifting arm 3212 is rotatably connected to the receiving seat 3214. The receiving seat 3214 is vertically movable relative to the frame 1. The receiving member 322 is fixedly connected to the receiving seat 3214.

[0080] Please combine Figures 2 to 4 and Figure 7The second conjugate cam 41 is fixed on the rotating shaft 22. The cutting assembly 42 includes a second transmission mechanism 421 and a cutting seat 422. The second transmission mechanism 421 connects the second conjugate cam 41 and the cutting seat 422 to drive the cutting seat 422 to rise and fall. The cutting seat 422 is provided with a cutting element 4223, which is located above the receiving element 322. Specifically, the second transmission mechanism 421 includes a second Y-shaped arm 4211, a second lifting arm 4212, and a second swing arm 4213. The second Y-shaped arm 4211 is rotatably connected to the frame 1. The second Y-shaped arm 4211 is driven by the second conjugate cam 41. The end of the second Y-shaped arm 4211 away from the second conjugate cam 41 is rotatably connected to the second lifting arm 4212. The end of the second lifting arm 4212 away from the second Y-shaped arm 4211 is rotatably connected to one end of the second swing arm 4213. The middle part of the second swing arm 4213 is rotatably connected to the frame 1. The end of the second swing arm 4213 away from the second lifting arm 4212 is rotatably connected to the cutting seat 422. The cutting seat 422 is vertically adjustable relative to the frame 1.

[0081] To prevent unexpected movement of the second strip, a third positioning post 4221 is provided on the cutting seat 422. The third positioning post 4221 is vertically adjustable relative to the cutting seat 422. Preferably, the cutting seat 422 is provided with a cutting reset member 4222, which drives the third positioning post 4221 to descend, meaning the third positioning post 4221 is floating relative to the cutting seat 422. When the third positioning post 4221 descends to a certain extent (touching the frame 1), and the cutting seat 4222 drives the cutting piece 4223 to continue descending, the third positioning post 4221 will not follow the cutting seat 422's descent. The third positioning post 4221 is used to position the second strip, preventing unexpected movement. The cutting reset member 4222 can be a spring, a spring sheet, an elastic colloid, etc.

[0082] Please combine Figures 2 to 4 and Figure 8The third conjugate cam 51 is fixed on the rotating shaft 22. The pressing assembly 52 includes a third transmission mechanism 521 and a pressing seat 522. The third transmission mechanism 521 connects the third conjugate cam 51 and the pressing seat 522 to drive the pressing seat 522 to rise and fall. The pressing seat 522 is provided with a pressing member 5221. Specifically, the third transmission mechanism 521 includes a third Y-shaped arm 5211 and a third lifting arm 5212. The third Y-shaped arm 5211 is rotatably connected to the frame 1. The third Y-shaped arm 5211 is in transmission cooperation with the third conjugate cam 51. The end of the third Y-shaped arm 5211 away from the third conjugate cam 51 is rotatably connected to the third lifting arm 5212. The end of the third lifting arm 5212 away from the third Y-shaped arm 5211 is connected to the pressing seat 522.

[0083] Preferably, the pressing member 5221 is vertically movable relative to the pressing base 522. The pressing base 522 is provided with a pressing reset member 5222, which is used to drive the pressing member 5221 to descend. The floating design of the pressing member 5221 can avoid hard contact between the pressing member 5221 and the second metal part 200, which could cause deformation or damage to the second metal part 200. At the same time, it can reduce the processing accuracy requirements and assembly accuracy requirements of the pressing assembly 52. ​​The pressing reset member 5222 can be a spring, a spring sheet, an elastic colloid, etc. Specifically, the contact portion of the pressing member 5221 is provided with a clearance opening 5223 (the contact portion is used to contact and press against the second metal member 200). The clearance opening 5223 is used to avoid the welding area between the first metal member 100 and the second metal member 200. This allows the contact portion and the second metal member 200 to have a larger contact area, thereby ensuring the welding quality of the first metal member 100 and the second metal member 200 to a greater extent. In this embodiment, the clearance opening 5223 is notched, that is, the contact portion of the pressing member 5221 and the second metal member 200 can form a contact area that semi-encloses the welding area, and the weld point produced by the welding device is located within the welding area.

[0084] The welding device is used to weld the second metal part 200 and the first metal part 100 pressed by the pressing member 5221. Preferably, the high-speed positioning cutting and welding integrated machine completes one cycle of work for each rotation of the rotating shaft 22 driven by the drive motor 21. In a single cycle, the welding time of the welding device is greater than or equal to the time required for the rotating shaft 22 to rotate 1 / 3 of a revolution. More preferably, the welding time of the welding device in a single cycle is the time required for the rotating shaft 22 to rotate half a revolution.

[0085] Please combine Figures 2 to 6The positioning cam 61 is fixed on the rotating shaft 22. The first positioning assembly 62 includes a fourth transmission mechanism 621 and a positioning seat 622. The fourth transmission mechanism 621 connects the positioning cam 61 and the positioning seat 622 to drive the positioning seat 622 to rise and fall. The positioning seat 622 is provided with a first positioning pin group, which includes a plurality of first positioning pins 6221. The first material strip has a first positioning hole that mates with the first positioning pins 6221. Specifically, the positioning cam 61 is a grooved cam. The fourth transmission mechanism 621 includes a fourth lifting arm 6211 and a third swing arm 6212. One end of the fourth lifting arm 6211 is drivenly connected to the positioning cam 61, and the other end of the fourth lifting arm 6211 is rotatably connected to one end of the third swing arm 6212. The middle part of the third swing arm 6212 is rotatably connected to the frame 1, and the other end of the third swing arm 6212 is rotatably connected to the positioning seat 622. In other embodiments, the positioning cam 61 may also be a conjugate cam, but compared to that, a grooved cam is more conducive to simplifying the structure and reducing the size.

[0086] like Figure 5 and Figure 6 As shown, to ensure precise positioning of the second metal part 200 on the receiving part 322, the positioning seat 622 is further provided with a second positioning pin group, which includes a plurality of second positioning pins 6222. The second metal part 200 has a second positioning hole that mates with the second positioning pins 6222, and the top surface of the receiving part 322 is provided with a through hole for the second positioning pins 6222 to pass through. To ensure sufficient contact area between the cutting part 4223 and the second metal part 200, the cutting part 4223 is provided with a clearance hole 4224 for avoiding the second positioning pins 6222.

[0087] Please combine Figures 2 to 5 Optionally, the frame 1 is provided with a welding seat 11, which is located in the first feed channel and below the pressing member 5221 and the cutting member 4223, and above the positioning seat 622 and the receiving seat 3214; the welding seat 11 is provided with a first through hole for the first positioning post 6221 to pass through and a second through hole for the receiving member 322 to pass through.

[0088] like Figure 4 and Figure 5 As shown, in order to improve the smoothness of the lifting and lowering of the positioning seat 622 and the receiving seat 3214, in this embodiment, the welding seat 11 is provided with a guide post 12, and the receiving seat 3214 and the positioning seat 622 are respectively provided with guide sleeves that cooperate with the guide post 12.

[0089] The working process of this high-speed positioning, cutting, and welding integrated machine is briefly described below:

[0090] The first conveyor belt is fed into position, and the second conveyor belt is fed into position.

[0091] The first conjugate cam 31 drives the first transmission mechanism 321 to raise the receiving part 322, so that the receiving part 322 receives the second metal part 200;

[0092] The positioning cam 61 drives the fourth transmission mechanism 621 to raise the positioning seat 622. The first positioning pin 6221 is inserted into the first positioning hole in the first material strip area on the welding seat 11, and the second positioning pin 6222 is inserted into the second positioning hole.

[0093] The second conjugate cam 41 drives the second transmission mechanism 421 to lower the cutting seat 422. The third positioning pin 4221 is inserted into the second strip. The cutting piece 4223 cuts the second metal piece 200 located at the head of the second strip from top to bottom. During the cutting process of the cutting piece 4223 cutting the second metal piece 200, when the cutting piece 4223 contacts the second metal piece 200, the first conjugate cam 31 drives the receiving piece 322 to achieve the same speed as the cutting piece 4223, so that the second metal piece 200 is separated from the second strip.

[0094] After the second metal part 200 contacts the first metal part 100, the third conjugate cam 51 drives the third transmission mechanism 521 to lower the pressure seat 522. The pressure seat 5221 contacts the second metal part 200, and the first metal part 100 and the second metal part 200 are clamped by the pressure seat 5221 and the welding seat 11. After that, the welding device can weld the first metal part 100 and the second metal part 200.

[0095] In a single cycle, the working time of the first feed component and the working time of the second feed component at least partially overlap, and both are staggered from the working time of the welding device.

[0096] When the cutting component 4223 is resetting upwards but has not yet completed resetting, the first feeding component feeds the first material strip.

[0097] As the cutting component 4223 descends, the pressing component 5221 also descends. In the cyclic operation, the starting time of the descent of the cutting component 4223 is earlier than the starting time of the descent of the pressing component 5221.

[0098] As a preferred embodiment, the working sequence of this high-speed positioning, cutting, and welding integrated machine is briefly described as follows:

[0099] When the welding time of the welding device in a single cycle is the time required for the rotating shaft 22 to rotate 1 / 3 revolution, such as Figure 9 As shown.

[0102] The welding device performs welding as the rotating shaft rotates from 180° to 300°.

[0104] During the rotation of the rotating shaft from 90° to 125°, the receiving component rises to its highest point. During the rotation of the rotating shaft from 125° to 145°, the receiving component remains stationary. During the rotation of the rotating shaft from 145° to 175°, the receiving component descends to a certain height (i.e., the second metal component it supports descends to the welding position). During the rotation of the rotating shaft from 175° to 315°, the receiving component remains stationary. During the rotation of the rotating shaft from 315° to 330°, the receiving component descends and resets.

[0105] During the rotation of the rotating shaft from 135° to 170°, the cutting piece descends; during the rotation of the rotating shaft from 170° to 315°, the cutting piece remains stationary; during the rotation of the rotating shaft from 315° to 345°, the cutting piece rises and returns to its original position.

[0106] During the process of the rotating shaft rotating from 330° to 360° and from 0° to 90°, the first feeding component feeds the first material belt.

[0107] When the welding time of the welding device in a single cycle is the time required for the rotating shaft 22 to rotate half a turn, such as Figure 10 As shown.

[0108] During the process of the rotating shaft rotating from 0° to 70° and from 345° to 360°, the second feeding assembly feeds the second material strip;

[0109] During the rotation of the rotating shaft from 35° to 70°, the positioning seat drives the first positioning column and the second positioning column to rise. During the rotation of the rotating shaft from 70° to 300°, the positioning seat remains stationary at the high point. During the rotation of the rotating shaft from 300° to 330°, the positioning seat drives the first positioning column and the second positioning column to descend and reset.

[0110] The welding device performs welding as the rotating shaft rotates from 120° to 300°.

[0111] During the rotation of the rotating shaft from 80° to 115°, the lower pressure component descends; during the rotation of the rotating shaft from 115° to 300°, the lower pressure component remains stationary; during the rotation of the rotating shaft from 300° to 330°, the lower pressure component rises and resets.

[0112] During the rotation of the rotating shaft from 35° to 70°, the receiving component rises to its highest point. During the rotation of the rotating shaft from 70° to 85°, the receiving component remains stationary. During the rotation of the rotating shaft from 85° to 115°, the receiving component descends to a certain height (i.e., the second metal component it supports descends to the welding position). During the rotation of the rotating shaft from 115° to 325°, the receiving component remains stationary. During the rotation of the rotating shaft from 325° to 340°, the receiving component descends and resets.

[0113] During the rotation of the rotating shaft from 75° to 110°, the cutting piece descends; during the rotation of the rotating shaft from 110° to 315°, the cutting piece remains stationary; during the rotation of the rotating shaft from 315° to 345°, the cutting piece rises and returns to its original position.

[0114] During the process of the rotating shaft rotating from 340° to 360° and from 0° to 35°, the first feeding assembly feeds the first material belt.

[0115] In summary, the high-speed positioning cutting and welding integrated machine provided by this invention has a novel structure. It ingeniously integrates multiple workstations and creatively utilizes cams to drive various mechanisms to complete all processes. This not only simplifies the equipment structure and reduces its overall size, but also requires only a single power source, effectively saving energy consumption. More importantly, this high-speed positioning cutting and welding integrated machine can significantly improve production efficiency and reduce production costs. Furthermore, the rational design of the work step sequence ensures that the welding time is greater than or equal to the time required for the rotating shaft to rotate 1 / 3 of a revolution, allowing for an increase in the rotational speed of the rotating shaft. This results in a shorter completion time for a single cycle, further improving the working efficiency of the high-speed positioning cutting and welding integrated machine. In particular, the working efficiency of the high-speed positioning cutting and welding integrated machine reaches its peak when the welding time is the time required for the rotating shaft to rotate half a revolution.
