Description

Technical Field

[0001] The present invention relates to an automatic production line for laser welding of a pot handle fixing seat, belonging to the technical field of pot manufacturing. Background Art

[0002] In the existing pot manufacturing process, there is a process of welding a pot handle fixing seat on the side of the pot body for subsequent installation and fixation of the pot handle. The pot handle fixing seat may be a nut seat or a bolt seat, and the welding surface of the pot handle fixing seat usually has an inclination angle of 0 to 25 degrees.

[0003] Due to the defects of manual argon arc welding operation such as high labor intensity, unstable quality, high scrap rate, and low efficiency, there have been technical reports on automatic welding of pot handle fixing seats in the prior art. For example, a Chinese utility model patent ZL 201921280212.4 discloses an automatic pot handle bolt welding device. Although this patented technology can effectively improve the welding efficiency compared with the manual welding method and basically ensure the welding consistency, this patent uses the resistance spot welding process. As is known to those skilled in the art, spot welding will have obvious weld seams and large welding slag splashes, resulting in an unaesthetic defect. Usually, it requires secondary grinding and post-treatment, which is cumbersome and affects the production efficiency and the qualified rate of finished products (currently, the highest welding efficiency can only reach 600 - 800 pieces per hour, and the highest qualified rate of finished products reaches 90%); the key is that the spot welding firmness is relatively low, and most can only achieve a torque of 12 - 13 N·m, which limits the service life of the pot and hinders the product competitiveness.

[0004] In addition, although it is known from the existing common knowledge that the laser welding technology has the advantages of high welding precision, beautiful weld seams, and high welding efficiency, there has been no report on an automatic laser welding technology that can realize the pot handle fixing seat, especially the special-shaped pot handle fixing seat with a certain inclination angle at the end face.

[0111] Embodiment

[0112] Please refer to Figures 1 to 5 As shown: An automatic production line for realizing laser welding of a pot handle fixing seat provided in this embodiment includes a laser welding mechanism 1, a pot handle fixing seat feeding mechanism 2, a multi-station cookware conversion table 3 and a frame 4. The laser welding mechanism 1 includes a welding laser 1-1, a laser welding head 1-2 and a two-axis interpolation motion mechanism 1-3 for realizing an inclined cylindrical weld track. The two-axis interpolation motion mechanism 1-3 includes a longitudinal circumferential rotary motion mechanism 1-31, a transverse horizontal linear motion mechanism 1-32 and a linkage seat 1-33.

[0113] Please refer to again Figure 5 and Figure 6 As shown: The longitudinal circumferential rotary motion mechanism 1-31 in this embodiment includes a rotary motor 1-311, a rotary bearing 1-312, a rotary bearing seat 1-313 and a welding head rotary plate 1-314. The laser welding head 1-2 is fixedly arranged on the welding head rotary plate 1-314 through a fixing seat 1-21 of the laser welding head. The welding head rotary plate 1-314 is fixedly connected to the rotary bearing 1-312, and the rotary bearing 1-312 is fixedly connected to the output shaft of the rotary motor 1-311. The linkage seat 1-33 is L-shaped. The rotary bearing seat 1-313 is fixedly connected to the longitudinal support 1-331 constituting the L-shaped linkage seat, and the transverse support 1-332 constituting the L-shaped linkage seat is slidably connected to the transverse horizontal linear motion mechanism 1-32.

[0114] The rotary motor 1-311 drives the rotary bearing 1-312 to perform a rotary circular motion, and then the welding head rotary plate 1-314 can be driven to perform a synchronous rotary circular motion, so that the rotary circular motion of the laser welding head 1-2 can be realized.

[0115] It should be noted here that the rotary bearing 1-312 and the rotary bearing seat 1-313 described in the present application can be directly replaced by a reducer adapted to the rotary motor 1-311.

[0116] Please refer to again Figure 5As shown: In this embodiment, the horizontal linear motion mechanism 1-32 includes a lead screw I 1-321, an adjusting nut I 1-322, a linear slide rail I 1-323, a slider I 1-324, and a welding substrate 1-325. The lead screw I 1-321 and the linear slide rail I 1-323 are both fixed on the welding substrate 1-325. The adjusting nut I 1-322 sleeved on the lead screw I 1-321 and the slider I 1-324 slid on the linear slide rail I 1-323 are both fixedly connected to the bottom surface of the horizontal support 1-332 that constitutes the L-shaped linkage seat. A welding substrate horizontal displacement adjusting mechanism 1-326 is provided at the bottom of the welding substrate 1-325.

[0117] By driving the linear motion between the lead screw I 1-321 (which can adopt driving methods such as electric, pneumatic, and manual. The electric drive is shown in the figure, but this design is not limited thereto) and the adjusting nut I 1-322, the slider I 1-324 fixed to the bottom surface of the horizontal support 1-332 that constitutes the L-shaped linkage seat can move horizontally along the linear slide rail I 1-323. Thus, the longitudinal circular rotary motion mechanism 1-31 installed on the longitudinal support 1-331 of the L-shaped linkage seat can move synchronously in a horizontal linear motion as a whole, realizing the two-axis interpolation motion combining the longitudinal circular rotary motion and the horizontal linear motion. Furthermore, the laser welding of the inclined cylindrical weld seam trajectory can be realized.

[0118] Please refer to Figure 5 and Figure 7 As shown: In this embodiment, the welding substrate horizontal displacement adjusting mechanism 1-326 includes a lead screw II 1-3261, an adjusting nut II 1-3262, a linear slide rail II 1-3263, a slider II 1-3264, and an adjusting base 1-3265. The lead screw II 1-3261 and the linear slide rail II 1-3263 are both fixed on the adjusting base 1-3265. The adjusting nut II 1-3262 sleeved on the lead screw II 1-3261 and the slider II 1-3264 slid on the linear slide rail II 1-3263 are both fixedly connected to the bottom of the welding substrate 1-325.

[0119] By driving the linear motion between the lead screw II 1-3261 (which can adopt driving methods such as electric, pneumatic, and manual. The manual crank drive is shown in the figure, but this design is not limited thereto) and the adjusting nut II 1-3262, the slider II 1-3264 fixed to the bottom of the welding substrate 1-325 can move horizontally along the linear slide rail II 1-3263. Thus, it drives the welding substrate 1-325 to move horizontally back and forth. By driving the welding substrate 1-325 to move horizontally back and forth, the horizontal welding position of the two-axis interpolation motion mechanism 1-3 located on the welding substrate 1-325 can be appropriately adjusted.

[0120] Please refer to Figure 7As shown: In this embodiment, the horizontal displacement adjusting mechanism 1-326 of the welding substrate may further include an electronic displacement ruler 1-3266. One end of the electronic displacement ruler 1-3266 is fixedly connected to the welding substrate 1-325, and the other end of the electronic displacement ruler 1-3266 is fixedly connected to the adjusting base 1-3265. At the bottom of the adjusting base 1-3265, there is a height jacking and adjusting mechanism I 1-3267, and a height-adjusting electronic digital display 1-3268 is fixedly installed on the adjusting base 1-3265.

[0121] The electronic displacement ruler 1-3266 can measure and display the specific value of the horizontal displacement of the welding substrate 1-325 before and after, and the height-adjusting electronic digital display 1-3268 can measure and display the specific value of the height change of the welding substrate 1-325. By enabling the welding substrate 1-325 to achieve horizontal displacement before and after and height adjustment up and down, it can ensure that the laser welding mechanism 1 is applicable to the adjustment of the welding positions required for various sizes and specifications of cookware.

[0122] Please refer to Figure 3 、 Figure 4 and Figure 8 As shown: In this embodiment, the laser welding mechanism 1 may further include a welding cable winding and unwinding mechanism 1-5.

One end of each short spoke 1-53 is fixedly connected to the welding head rotary plate 1-314, and the other end of each short spoke 1-53 is fixedly connected to the inner wall of the inner ring 1-51. One end of each middle spoke 1-54 is fixedly connected to the corresponding short spoke 1-53 through a support foot 1-56. Each long spoke 1-55 is fixedly connected to the back of the outer ring 1-52, and the welding cable 1-4 is wound and unwound around the outer peripheral surface of the inner ring 1-51.

[0124] Through the above design, the welding cable 1-4 and the welding head rotary plate 1-314 can perform synchronous high-speed circular rotary motion, so as to ensure that when the laser welding head 1-2 performs high-speed circular rotary welding, the welding cable 1-4 can move smoothly without being damaged or hindered, affecting the high-speed circular rotary motion of the laser welding head 1-2.

[0146] Please also combine with Figure 2 and Figures 22 to 24 as shown: The automatic production line described in this embodiment may further include an automatic cleaning mechanism 10 for the welding surface of the pot. The automatic cleaning mechanism 10 includes a laser marking machine 10-1 and a position adjustment mechanism 10-2. The position adjustment mechanism 10-2 includes a pitching angle adjustment mechanism 10-21, an up and down position adjustment mechanism 10-22, and a front and back horizontal position adjustment mechanism 10-23. The laser marking machine 10-1 is connected to the pitching angle adjustment mechanism 10-21, the pitching angle adjustment mechanism 10-21 is connected to the up and down position adjustment mechanism 10-22, and the up and down position adjustment mechanism 10-22 is connected to the front and back horizontal position adjustment mechanism 10-23.

[0147] In use, generally, first, the horizontal position adjustment mechanism 10-23 moves the laser marking machine 10-1, the pitching angle adjustment mechanism 10-21, and the vertical position adjustment mechanism 10-22 synchronously to a horizontal position suitable for the cookware to be cleaned. Then, the vertical position adjustment mechanism 10-22 moves the laser marking machine 10-1 and the pitching angle adjustment mechanism 10-21 synchronously to a height position suitable for the cookware to be cleaned. Next, the pitching angle adjustment mechanism 10-21 adjusts the pitching angle of the laser marking machine 10-1 to a cleaning angle suitable for the cookware to be cleaned.

[0148] Specifically, in this embodiment:

[0149] The pitching angle adjustment mechanism 10-21 includes a rotating plate 10-211 and a Z-direction fixing plate 10-212. The rotating plate 10-211 is rotatably connected to the Z-direction fixing plate 10-212 (in this embodiment, it is connected by a pin shaft 10-213); arc-shaped grooves 10-2111 are provided at the front and rear parts of the rotating plate 10-211, and locking bolts 10-2112 are provided in the arc-shaped grooves 10-2111. The laser marking machine 10-1 is fixedly connected to the rotating plate 10-211 through a connecting seat 10-11.

[0150] When the pitching angle of the laser marking machine 10-1 needs to be adjusted, first manually loosen the locking bolt 10-2112, then manually rotate the rotating plate 10-211. When the pitching angle of the laser marking machine 10-1 is appropriate, then manually tighten the locking bolt 10-2112 to fix the rotating plate 10-211 to the Z-direction fixing plate 10-212.

[0151] The vertical position adjustment mechanism 10-22 includes a Z-direction mounting plate 10-221. A Z-direction screw-nut pair 10-222, a Z-direction linear slide rail 10-223, and a Z-direction slider 10-224 slidably arranged on the Z-direction linear slide rail 10-223 are provided on the Z-direction mounting plate 10-221. The nut 10-2221 in the Z-direction screw-nut pair and the Z-direction slider 10-224 are both fixedly connected to the Z-direction fixing plate 10-212.

[0152] When the Z-axis screw-nut pair 10-222 is driven (which can be driven manually, electrically, pneumatically, hydraulically, etc.) to move linearly, it can drive the Z-axis fixed plate 10-212 fixedly connected to the nut 10-2221 in the Z-axis screw-nut pair and the Z-axis slider 10-224 to move up and down. Since the laser marking machine 10-1 is fixedly connected to the rotating plate 10-211 through the connecting seat 10-11, and the rotating plate 10-211 is fixed to the Z-axis fixed plate 10-212 when adjusting the up and down position, adjusting the up and down position of the Z-axis fixed plate 10-212 can indirectly adjust the up and down position of the laser marking machine 10-1.

The nut fixing seat 10-2321 in the Y-axis screw-nut pair is vertically fixed to the bottom of the Z-axis mounting plate 10-221.

[0154] When the Y-axis screw-nut pair 10-232 is driven (which can be driven manually, electrically, pneumatically, hydraulically, etc.) to move horizontally in the front and rear direction, it can drive the Z-axis mounting plate 10-221 fixedly connected to the nut fixing seat 10-2321 in the Y-axis screw-nut pair to move horizontally in a straight line. Since the Z-axis fixed plate 10-212 is fixedly connected to both the nut 10-2221 in the Z-axis screw-nut pair and the Z-axis slider 10-224, and the Z-axis screw-nut pair 10-222 and the Z-axis linear slide rail 10-223 are both fixedly connected to the Z-axis mounting plate 10-221, when the Z-axis mounting plate 10-221 moves horizontally in a straight line, it can indirectly drive the Z-axis fixed plate 10-212 to move horizontally in a straight line, and thus indirectly adjust the front and rear horizontal position of the laser marking machine 10-1.

[0155] In a further implementation, a reinforcing rib plate 10-24 is provided between the Z-axis mounting plate 10-221 and the nut fixing seat 10-2321 in the Y-axis screw-nut pair.

[0156] In a further implementation, the Y-axis mounting plate 10-231 is fixedly connected to the X-axis frame support 4-1.

[0176] Please refer to again Figure 1 and Figure 2 As shown, the process of automatically welding the pot handle fixing seat using the automatic production line described in the above embodiment of the present invention is as follows:

[0177] 1) When the pan feeding mechanism 7 transports the pan 6 to the discharge port (which can be sensed by the opposed fiber optic sensors 7-1 arranged at the discharge port), the CCD camera 8-1 in the pan placement position detection mechanism 8 captures visual images of the pan;

[0178] 2) The automatic controller 14 compares the captured image with the standard image pre-stored in the system (usually using the trademark position information at the bottom of the pan as the judgment benchmark), and outputs position adjustment information to the pan loading and position adjustment mechanism 9;

[0179] 3) The vacuum chuck I 9-1 in the pan loading and position adjustment mechanism 9 sucks the pan, adjusts the position of the sucked pan 6 through the rotation of the rotation mechanism 9-2, and then transports it to the multi-station pan conversion table 3 through the horizontal displacement mechanism I 9-4;

[0180] 4) The multi-station pan conversion table 3 rotates to the automatic cleaning station, and the pressing and positioning mechanism 12 located above this station descends to press the pan, and then the automatic cleaning mechanism 10 is used to remove the coating and clean the welding surface (it should be noted here that: if the pan to be welded is a smooth pan, that is, there is no coating on the welding surface that needs to be removed, this station can also be omitted);

[0181] 5) The multi-station pan conversion table 3 rotates to the laser welding station, and the pressing and positioning mechanism 12 located above this station descends to press the pan, and then the pan handle fixing seat feeding mechanism 2 blows the pan handle fixing seat to the discharge head 2-14 through the air blowing and pushing mechanism 2-1, and the pan handle fixing seat 5 located at the mouth of the discharge head 2-14 is pushed and pressed on the welding surface of the pan 6 through the pushing and flipping mechanism 2-17, and then the laser welding of the inclined cylindrical weld track is realized by using the biaxial interpolation motion mechanism 1-3;

[0182] 6) After welding, the multi-station pan conversion table 3 rotates to the torque detection station, and the pressing and positioning mechanism 12 located above this station descends to press the pan, and then the torque detection mechanism 11 is used to detect the welded pan handle fixing seat 5 with the qualified standard torque;

[0183] 7) If the torque detection result is a qualified product (that is: under the torsion with the qualified standard torque, the pan handle fixing seat 5 does not rotate), it is sucked and transported to the qualified product conveyor belt 13-7 by the vacuum chuck in the finished product unloading mechanism 13; if the torque detection result is a non-qualified product (that is: under the torsion with the qualified standard torque, the pan handle fixing seat 5 rotates), it is sucked and transported to the non-conforming product conveyor belt 13-8 by the vacuum chuck in the finished product unloading mechanism 13.

[0184] As can be seen from the above: The present invention can not only achieve the automatic laser welding of the pot handle fixing seat, with the advantages of beautiful appearance and high welding efficiency. The key is that the present invention can make the torque of the pot handle fixing seat reach 15 - 25 N.m, which can be 20% - 70% higher than the prior art (most of the existing automatic welding technologies can only achieve a torque of 12 - 13 N.m), significantly extending the service life of the cookware, and the qualified rate of the finished products can be as high as over 99%, which has important value and significance for enhancing the competitiveness of cookware manufacturing enterprises; in addition, the automatic production line of the present invention can not only be applicable to cookware of different size specifications, but also be applicable to the welding of the pot handle fixing seat with an inclination angle, with strong versatility and a wide range of applications.

[0185] Finally, it is necessary to point out here that: The above description is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
