[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 As shown, a laser welding device for electronic communication products includes a base 1, a welding device 3 is fixedly connected to the middle of the upper end of the base 1, a conveying structure 2 arranged on the left and right sides of the welding device 3 is fixedly connected to the upper end of the base 1, a feeding structure 4 overlapped with the upper end of the conveying structure 2 is fixedly connected to the left side of the upper end of the base 1, a support frame 6 is fixedly connected to the upper end of the welding device 3, and a control cabinet 5 is fixedly connected to the rear of the upper end of the welding device 3.

[0034] It should be particularly noted that the above-mentioned control cabinet 5 is a conventional control terminal, which is used to control the actions of the conveying structure 2 and the welding equipment 3 in the control device, so as to coordinate the feeding frequency of the conveying structure 2 and the processing frequency of the welding equipment 3 to achieve continuous production. It is a commonly used control method in modern production equipment, and its internal structure and operating principle are not additionally displayed and explained in the present invention.

[0035] Further, in order to realize the feeding and discharging of the metal shell of the electronic product, refer to Figure 2 The conveying structure 2 includes a driving motor 22 fixedly connected to the front end of the welding equipment 3 and a feed conveyor belt 21 and a discharge conveyor belt 23 installed on the upper end of the base 1 through a bracket fixed on the upper end. The feed conveyor belt 21 and the discharge conveyor belt 23 are both transmission-connected to the driving motor 22 and their moving directions are opposite. The feed conveyor belt 21 is located on a side close to the feeding structure 4 and the conveying direction is backward conveying. The discharge conveyor belt 23 is located on a side away from the feeding structure 4 and the conveying direction is forward conveying.

[0036] The driving motor 22 is a conventional motor used to drive the feed conveyor belt 21 and the discharge conveyor belt 23 on both sides. The output directions on both sides are opposite through the action of the coupling, thereby driving the feed conveyor belt 21 and the discharge conveyor belt 23 to transport the metal shell in different directions.

[0037] Further, in order to realize feeding into the welding device 3, refer to Figure 2 The feeding structure 4 includes a mounting frame 41 fixedly connected to the right upper end of the base 1, a telescopic rod 42 is fixedly connected to the upper end of the mounting frame 41 close to the feeding conveyor belt 21, a piston rod at the output end of the telescopic rod 42 is fixedly connected to a Z-shaped rod 43, a middle part of the vertical part of the Z-shaped rod 43 is fixedly connected to the piston rod at the output end of the telescopic rod 42, a horizontal part of the Z-shaped rod 43 is unidirectionally connected to the end away from the telescopic rod 42 with a one-way flap 44, the one-way flap 44 only rotates to the side away from the telescopic rod 42, and a rectangular frame formed by the one-way flap 44 and the Z-shaped rod 43 is located on the upper side of the feeding conveyor belt 21.

[0038] In the initial state, half of the telescopic rod 42 is above the feed conveyor belt 21, and the other half is suspended in the air. The one-way flap 44 rotatably connected to the left part and the right half together form a rectangular frame. The size of this rectangular frame is determined by the size of the electronic communication product to be processed in the actual production process. When the feed conveyor belt 21 feeds inward, the unwelded shell enters the range of the Z-shaped rod 43 and the one-way flap 44, and the shell is sent to the inside of the welding equipment 3 by extending the telescopic rod 42. The welding equipment 3 is provided with a magnetic part that can absorb the metal shell. When the telescopic rod 42 retracts, the shell is sucked, the one-way flap 44 opens, retreats to the upper side of the feed conveyor belt 21 and returns to the initial state. At this time, the feed conveyor belt 21 continues to feed and can send the new shell into the range of the one-way flap 44 and the Z-shaped rod 43.

[0039] Further, to achieve the positioning, fixing and welding of materials, refer to Figure 3 and Figure 4 The welding equipment 3 includes a welding table 31 fixedly connected to the upper end of the base 1, the upper end of the welding table 31 is fixedly connected to the lower end of the support frame 6, an electric telescopic rod 34 is fixedly installed on the upper end of the horizontal part of the support frame 6, and a top pressure structure 33 is arranged at the output end of the electric telescopic rod 34. A bottom support structure 36 is arranged in the middle of the upper end of the welding table 31, and a welding structure 35 is arranged on the outer surface of any vertical part of the support frame 6. Four groups of positioning structures 32 are arranged in a circular distribution around the bottom support structure 36 at the upper end of the welding table 31, a central groove 311 is opened in the middle of the upper end of the welding table 31, and sliding grooves 312 are opened symmetrically around the cable 2 331 on the welding table 31.

[0040] During the operation of this embodiment, after the metal shell enters the range of the welding equipment 3, it will be adsorbed by the bottom support structure 36, and the electric telescopic rod 34 drives the top pressure structure 33 to move downward under the action of the control cabinet 5. At this time, the bottom support structure 36 is driven to rise under the cooperation of the top pressure structure 33 and the bottom support structure 36, and the metal shell is positioned by the cooperation of the bottom support structure 36 and the positioning structure 32. After the positioning is completed, the positioning structure 32 is reset by the action of the bottom support structure 36, and the top pressure structure 33 and the bottom support structure 36 are used to clamp and fix it. The metal shell is synchronously driven to tilt by the action of the welding structure 35 and the bottom support structure 36, so that its bending surface is within the range of the welding structure 35, and the cooperation of the welding structure 35 and the bottom support structure 36 is used to realize rotation after welding one side. After the welding is completed and the bending is completed on all sides, the shell is ejected by the feeding action of the feeding structure 4 to realize continuous processing.

[0041] Embodiment 2. Based on embodiment 1, in the process of the electric telescopic rod 34 driving the top pressure structure 33 to descend, the support rod 363 is further pulled by the second cable 331 to push the magnetic seat 361 to rise, and the metal shell adsorbed on the magnetic seat 361 is lifted. In this process, the positioning structure 32 is driven to move synchronously by the cooperation of the second cable 331 and the linkage component 366, so that the slider 1 324 drives the contact block 326 to slide in the limit groove 321 in the direction close to the magnetic seat 361 and contact with the edge of the metal shell. The metal shell is straightened by the synchronous push of the surroundings to achieve automatic positioning. The positioning structure 32 is reset by the action of the linkage component 366 after the rubber disk 335 contacts the metal shell to avoid interference with the rotation of the shell during welding.

[0042] Specifically, in order to achieve the clamping and fixing of the metal shell, and drive the bottom support structure 36 and the positioning structure 32 to move synchronously, position and clamp it, refer to Figure 5 The top pressure structure 33 includes a limit plate 332 fixedly connected to the piston rod at the output end of the electric telescopic rod 34. The limit plate 332 is nail-shaped and the lower part of the outer surface of its vertical part is slidably connected to a sliding rod 334. The lower end of the sliding rod 334 is rotatably connected to a rubber plate 335. The upper end of the rubber plate 335 is rotatably connected to a compression spring 333 fixedly connected to the lower end of the horizontal part of the limit plate 332. The upper end of the limit plate 332 is symmetrically fixedly connected to a cable 331 that bypasses the support frame 6 and extends to the inner cavity of the welding table 31 and is connected to the bottom support structure 36.

[0043] The limit plate 332 will move gradually downward as the piston rod of the electric telescopic rod 34 extends. During this process, the bottom support structure 36 will be pulled by the cable 2 331 to move synchronously with its movement. After the rubber plate 335 contacts the upper side of the metal shell, the compression spring 1 333 will be compressed. At this time, the distance between the rubber plate 335 and the limit plate 332 is shortened, so that the metal shell is tightly squeezed between the bottom support structure 36 and the rubber plate 335. At the same time, the rubber plate 335 is rotating, so it will not affect the rotation of the metal shell.

[0044] Further, in order to lift the metal shell so that it enters the action range of the welding structure 35, refer to Figure 6The bottom supporting structure 36 includes a supporting rod 363 which is slidably connected to the inner surface of the central groove 311, the upper end of the supporting rod 363 is rotatably connected to a magnetic seat 361, the lower end of the magnetic seat 361 is fixedly connected to a driving rod 364, the lower end of the driving rod 364 passes through the upper end of the supporting rod 363 and extends to the lower end of the supporting rod 363 and is rotatably connected to the inner surface of the supporting rod 363 through a slip ring, the outer surface of the supporting rod 363 is fixedly connected to a compression spring 2 362 which is fixedly connected to the middle part of the inner surface of the central groove 311, the lower part of the outer surface of the driving rod 364 is provided with a driving assembly 365 which is fixedly connected to the sliding seat 351, the lower part of the outer surface of the driving rod 364 is fixedly connected to the two adjacent cables 2 331, and the outer surface of the cable 2 331 which is located in the sliding groove 312 is provided with a linkage component 366 together with the positioning structure 32.

[0045] When the limit plate 332 is descending, the support rod 363 will slide upward in the central groove 311 through the cable 2 331. At this time, the driving rod 364 and the magnetic seat 361 will rise along with the rise of the support rod 363, and the synchronous compression spring 2 362 will be stretched. After the cable 2 331 is reset, the magnetic seat 361 and the support rod 363 are reset through the compression spring 2 362.

[0046] Further, in order to achieve the positioning of the metal shell by pushing the four edges of the metal shell inward from all sides to make it straight, refer to Figure 7 The positioning structure 32 includes a limiting groove 321 symmetrically opened along the axis of the magnetic seat 361 at the upper end of the welding table 31, and L-shaped guide grooves 322 are symmetrically opened along the center of the limiting groove 321 on the inner surfaces of the two limiting grooves 321, and the inner surfaces of the two L-shaped guide grooves 322 on the same side are slidably connected with a contact block 326, and the lower ends of the two contact blocks 326 are respectively fixedly connected with spring limiting rods 325, and the lower ends of the spring limiting rods 325 are fixedly connected with a slider 1 324 slidably connected to the lower part of the inner surface of the limiting groove 321, and the end of the slider 1 324 away from the magnetic seat 361 is fixedly connected with a compression spring 323 fixedly connected to the inner wall of the limiting groove 321, and the end of the slider 1 324 close to the magnetic seat 361 is fixedly connected with a cable 327 fixedly connected to the bottom supporting structure 36 on the same side.

[0047] Further, in order to achieve the inward movement of the L-shaped guide groove 322 during the positioning stage and to facilitate its reset after the positioning is completed, so as to avoid affecting the rotation of the metal shell during the welding stage, refer to Figure 8The linkage component 366 includes a slider 2 3661 and a slider 3663 which are slidably connected to the inner surface of the sliding groove 312. The slider 2 3661 is located on the upper side of the slider 3 3663 and is fixedly connected to the cable 3 327. The slider 3 3663 is fixedly connected to the outer surface of the cable 2 331. The lower end of the slider 2 3661 is symmetrically fixedly connected with a buckling rod 3662. The upper end of the slider 3 3663 is provided with a through hole which is compatible with the buckling rod 3662. The bottom wall of the inner surface of the sliding groove 312 is also provided with a release groove 3664 which is compatible with the buckling rod 3662.

[0048] In summary, when the second cable 331 is pulled, its part located in the sliding groove 312 moves downward. In the initial state, the second slider 3661 is located at the uppermost side, and the buckle rod 3662 on the lower side of the second slider 3661 is buckled with the third slider 3663. At this time, the first slider 324 is located in the limiting groove 321 on the side away from the magnetic seat 361 under the action of the compression spring 323. At this time, the contact block 326 is lower than the upper edge of the limiting groove 321 under the action of the L-shaped guide groove 322. When the second cable 331 is pulled, it will be connected to the third slider 3663 through the buckle rod 3662. The buckling of the slider 2 3661 drives the slider 2 3661 to slide downward in the sliding groove 312 synchronously. At this time, the slider 2 3661 pulls the cable 3 327 to move downward, and pulls the slider 1 324 to slide in the limit groove 321 toward the magnetic seat 361 through the cable 327. In this process, under the guidance of the L-shaped guide groove 322, the contact block 326 rises and contacts the edge of the metal shell to push it. Since the contact blocks 326 are distributed around the magnetic seat 361, the metal shell can be straightened with the central axis of the magnetic seat 361 as a reference, so as to fix the position of the metal shell.

[0049] Furthermore, in the process that the rubber disc 335 is in contact with the upper side of the metal shell and compresses the compression spring 1 333, the buckle rod 3662 contacts the lower unlocking groove 3664 and is squeezed and separated from the support rod 363. At this time, under the action of the compression spring 323, the slider 1 324 is reset and drives the contact block 326 to reset together. At this time, the contact block 326 is retracted to the inner side of the limit groove 321 under the guidance of the L-shaped guide groove 322, and will not affect the rotation of the metal shell.

[0050] At the same time, after the top pressing structure 33 is reset, the buckling rod 3662 and the sliding block 3663 will buckle together again on the upper side of the sliding groove 312 under the pressure provided by the compression spring 2 362 .

[0051] Embodiment 3: Based on embodiment 2, this embodiment further drives the threaded rod 352 to rotate through the stepper motor 354, thereby driving the sliding seat 351 to slide up and down on the vertical surface of the support frame 6, and the laser emitter 353 is driven up and down by the sliding seat 351 to perform laser welding on the gaps at the two bends, and synchronously drives the magnetic seat 361 to rotate through the driving rod 364 through the cooperation of the cable 1 355 and the driving assembly 365, thereby driving the metal shell to rotate, thereby realizing the sequential welding of the four corners, reducing the process of repeated placement, and thus improving production efficiency.

[0052] Specifically, to achieve welding of the gap at the bend of the metal shell, refer to Fig. 9 The welding structure 35 includes a sliding seat 351 slidably connected to the vertical part of the support frame 6. The end of the sliding seat 351 close to the electric telescopic rod 34 is fixedly connected to a laser transmitter 353 connected to the control cabinet 5 through a cable. The inner surface of the sliding seat 351 is threadedly connected to a threaded rod 352 rotatably connected to the upper end of the welding table 31. The lower end of the threaded rod 352 is fixedly connected to a stepping motor 354 fixedly connected to the upper end of the welding table 31. The lower end of the sliding seat 351 is fixedly connected to a cable 355 connected to the bottom support structure 36.

[0053] Further, in order to realize the turning of the shell after welding a gap, refer to Fig.10 The driving assembly 365 includes a rack 3652 which is slidably connected to the inner surface of the second cable 331, one end of the rack 3652 is fixedly connected to the cable 1 355, the end of the rack 3652 away from the cable 1 355 is fixedly connected to the compression spring 4 3651 which is fixedly connected to the inner cavity of the welding table 31, the end of the rack 3652 close to the driving rod 364 is meshed with a gear 3653 which is rotatably connected to the bottom wall of the inner cavity of the welding table 31, the inner surface of the gear 3653 is fixedly connected to a one-way bearing 3654, and the driven side of the one-way bearing 3654 is slidably connected to the outer surface of the driving rod 364.

[0054] In summary, the threaded rod 352 is driven to rotate by the action of the stepper motor 354, thereby driving the sliding seat 351 to slide on the vertical plane of the support frame 6, thereby driving the laser emitter 353 to move in the up and down directions. Two position sensors are also arranged on the column of the support frame 6. In the initial state, the sliding seat 351 is located between the two sensors, and the top pressure structure 33 presses down to fix the metal shell. After the positioning structure 32 returns to the initial position, the stepper motor 354 drives the laser emitter 353 to rise to the upper sensor position. At this time, the cable 1 355 is relatively tight, and the rack 3652 reaches the front side under the traction of the compression spring 4 3651, thereby driving the gear 3653 to rotate. The gear 3653 drives the driving rod 364 and the magnetic seat 361 on its upper side to rotate through the one-way bearing 3654. Since the magnetic seat 361 and the rubber disk 335 clamp the metal shell, the shell will be synchronously driven to rotate 45 degrees while rotating, so that the corners and the laser emitter 353 are on the same vertical line;

[0055] Furthermore, the stepper motor 354 drives the threaded rod 352 to rotate, thereby driving the sliding seat 351 to move downward along the support frame 6, the laser emitter 353 welds the gap of the metal shell, the cable 1 355 is relaxed relative to the rack 3652, and the rack 3652 moves backward under the action of the compression spring 4 3651. Since the one-way bearing 3654 is a one-way transmission, the resistance formed by the pressure of the upper side pressure structure 33 on the driving rod 364 at this time will not generate transmission;

[0056] After reaching the lower sensor position, the stepper motor 354 reverses to drive the sliding seat 351 to rise. At this time, the laser emitter 353 will not perform welding. The sliding seat 351 moves forward by pulling the rack 3652 through the cable 1 355. At this time, the rotation of the gear 3653 will drive the one-way bearing 3654 to rotate synchronously, thereby driving the driving rod 364 and the magnetic seat 361 on its upper side to rotate, thereby driving the magnetic seat 361 to rotate 90 degrees, and rotating the next welding point into the range of the laser emitter 353 until the sliding seat 351 reaches the upper sensor position;

[0057] It should be noted that the laser emitter 353 is only a launch device of the laser welder, and its main equipment is located inside the control cabinet 5. Its application and operation methods are mature technical means in the prior art. The present invention does not involve its detailed structure, and its internal structure and operation principle will not be displayed and explained.

[0058] In addition, the two sensors installed on the support frame 6 can transmit signals to the control cabinet 5 after being blocked, and control the start and stop, forward and reverse operation of the stepper motor 354 through the control cabinet 5. They are conventional sensors, and their specific information will not be repeated in the present invention;

[0059] The one-way bearing 3654 can drive the inner ring, that is, the output shaft, to rotate synchronously when the outer ring rotates forward, and the inner ring is not affected when the outer ring rotates reversely. This type of bearing part has been widely used in modern transmission methods, and its implementation method and specific structure are mature means in the prior art, and its detailed structure will not be displayed and explained in the present invention.
