The number of the welding fixtures 4 is multiple, preferably two. The welding device for the left and right baffles of the lower housing in a gas filter unit of the present invention significantly improves the production efficiency, reduces the labor cost, while ensuring the consistency and stability of the welding quality through automated and intelligent welding technology, effectively solving the problems existing in traditional manual welding. The popularization and application of this device will provide strong support for the manufacture of filter absorber products in the civil air defense industry, promoting industrial upgrading and technological progress.

[0043] Specifically, as Figures 2 to 5 shown, as a specific setting mode of the automatic discharging component 1, the automatic discharging component 1 includes a vibrating disk hopper 11. An outlet guide rail 12 is arranged at the outlet of the vibrating disk hopper 11. A material arranging device 13 is arranged in the middle of the outlet guide rail 12. A stop plate 14, a discharging device 15, and the receiving block device 16 are arranged at the discharging end of the outlet guide rail 12. The material arranging device 13 includes an upper female die 131 and a lower male die 132 respectively arranged at the top and bottom of the outlet guide rail 12. The shapes of the upper female die 131 and the lower male die 132 match the shape of the baffle 6. The upper female die 131 is fixed, and the lower male die 132 reciprocates in the vertical direction relative to the upper female die 131.

[0044] The front view projection of the baffle 6 has a "door" - shaped structure with a closed top and an open bottom. The lower housing 7 has a rectangular box - shaped structure. Three sides of the lower housing 7 are closed, and the bottom has an opening. The baffle 6 is welded and fixed inside the bottom opening of the lower housing 7. The inside of the upper female die 131 has a rectangular structure, and the inside of the lower male die 132 has a shape similar to an "M", and the two bottom sides of the shape similar to an "M" have a wedge - shaped structure with the tip facing downwards. A first cylinder 133 is arranged at the top of the upper female die 131, and the piston rod of the first cylinder 133 can extend into the inside of the upper female die 131. A second cylinder 134 is arranged at the bottom of the lower male die 132, and the piston rod of the second cylinder 134 can extend into the inside of the lower male die 132.

[0045] The discharging device 15 includes a position sensor 151, a horizontal cylinder 152, and a vertical cylinder 153; the position sensor 151 is electrically connected to the horizontal cylinder 152 and the vertical cylinder 153. The piston rod of the vertical cylinder 153 is fixedly connected to the piston rod of the horizontal cylinder 152 through a fixing block 154. The piston rod of the vertical cylinder 153 is connected with a first vacuum suction cup 155 for adsorbing the baffle 6 on the discharging guide rail 12 through a "Z"-shaped connecting plate. The first vacuum suction cup 155 is communicated with the air source through a connecting pipe interface. The material receiving block device 16 includes a first linear module 161 arranged in parallel on one side of the discharging guide rail 12. A material receiving block 162 fixedly connected to its own slider is arranged on the first linear module 161. At least one notch 163 for fixing the baffle 6 is arranged on the material receiving block 162.

[0046] The working principle of the automatic discharging assembly 1 is as follows: Workers pour the baffle 6 workpieces into the vibrating bowl hopper 11. The vibrating bowl hopper 11 sequentially sends out the left and right baffle 6 workpieces with conforming postures to the discharging guide rail 12. The baffle 6 moves forward on the discharging guide rail 12. After the baffle 6 reaches the shaping device 13, the lower punch 132 is driven by the second cylinder 134 to move upward, so that the baffle 6 contacts the upper die 131 fixed above, thereby achieving the function of shaping the workpiece. After the shaping is completed, the workpiece can be completely separated from the upper die 131 under the action of the first cylinder 133 above. The workpiece after shaping continues to move forward. After reaching the position of the discharging device 15, the position sensor 151 is triggered. After receiving and sending out a signal, the position sensor 151 controls the vertical cylinder 153 to extend downward by the PLC. The first vacuum suction cup 155 is turned on to suck the baffle 6 under negative pressure. The vertical cylinder 153 retracts, the horizontal cylinder 152 extends, and the material receiving block 162 above the first linear module 161 moves to the designated position through the linear module. The linear module is powered by a servo motor. The vertical cylinder 153 extends downward, the first vacuum suction cup 155 closes the air intake, and the baffle 6 is placed at the notch 163 of the material receiving block 162. The vertical cylinder 153 retracts, and then the horizontal cylinder 152 retracts, thereby completing the discharging of one baffle 6 workpiece. After the discharging is completed, the linear module moves forward to align the next notch 163 of the material receiving block 162 with the receiving position. Repeat the above steps to complete the discharging of the workpieces in multiple notches 163 on the material receiving block 162, so as to realize the discharging of the baffle 6 placed at equal intervals and wait for the gripping and loading assembly 3 to grip.

[0047] Specifically, as Figure 6As shown, as a specific way of the grasping and feeding component 3, the grasping and feeding component 3 includes a three-axis moving platform arranged on the support platform 2. The three-axis moving platform includes a portal-shaped bracket 31. On both sides of the portal-shaped bracket 31 in the length direction, a vertical linear module 32 is respectively arranged. A horizontal fixing plate 33 is fixed on the sliders of the two vertical linear modules 32. A horizontal linear module 34 is arranged on the horizontal fixing plate 33. A connecting bracket 35 in a "7" - shaped structure is connected to the slider of the horizontal linear module 34. The inner side of the vertical end of the connecting bracket 35 is fixedly connected to the slider of the horizontal linear module 34. On the top surface of the horizontal end of the connecting bracket 35, a first Y - direction cylinder 36 is arranged. A vertical plate 37 is connected to the piston rod of the first Y - direction cylinder 36. At least one second vacuum suction cup 38 is fixed at the bottom of the vertical plate 37. Each second vacuum suction cup 38 is communicated with the air source through a connecting pipe interface. The second vacuum suction cup 38 is located at the top of the receiving block 162.

[0048] The working principle of the grasping and feeding component 3 is as follows: The vertical linear module 32 moves downward to drive the three second vacuum suction cups 38 to move downward. The second vacuum suction cups 38 work and suck three baffle plates 6 at the same time. The vertical linear module 32 moves upward, and then moves to the specified position to the right by the horizontal linear module 34. The first Y - direction cylinder 36 extends, and moves the three baffle plates 6 to the fixed position 42 of the welding fixture 4. The second vacuum suction cups 38 release the three baffle plates 6 onto the three fixed positions 42 of the support frame 41. The vertical linear module 32 drives the three second vacuum suction cups 38 to reset, and then the feeding process of the baffle plate 6 can be completed, waiting for the welding of the welding component 5.

[0049] Specifically, as Figure 7 and Figure 8 shown, as a specific setting way of the welding fixture 4, the welding fixture 4 includes a support frame 41 located at the top of the support platform 2. A plurality of uniformly spaced fixed positions 42 are arranged in the length direction of the support frame 41. Each fixed position 42 is used to fix a baffle plate 6. On both sides of each fixed position 42, a guiding bracket 43 is arranged. The top of each guiding bracket 43 is in a triangular structure with the tip facing upward. The width of each guiding bracket 43 matches the internal dimension of the bottom opening of the lower shell 7. The guiding bracket 43 is used for guiding and fixing the lower shell 7.

[0050] The welding fixture 4 further includes a clamping device. The clamping device includes two clamping cylinders 44 respectively located on both sides of the support frame 41 in the width direction. A clamping plate 45 is connected to the piston rod of each clamping cylinder 44. The two clamping plates 45 are respectively located outside the front and back of the lower shell 7.

[0051] A rotating tray 46 is provided at the bottom of the support frame 41. The servo motor drives the rotating tray 46 to rotate about its own axis. The bottom of the rotating tray 46 is fixedly connected to the support platform 2, and the top of the rotating tray 46 is fixedly connected to the bottom of the support frame 41. A rotating limit device is provided on the bottom surface of the top of the support platform 2 on one side of the rotating tray 46. The rotating limit device includes a vertically arranged third cylinder 47. A limit hole matching the piston rod of the third cylinder 47 is provided at the bottom of the support frame 41. The welding assembly 5 is located on one side of the support frame 41.

[0052] Specifically, as Figure 9 shown, the welding assembly 5 includes a second linear module 51, a laser welding gun 52 and a second Y-direction cylinder 53. The second linear module 51 is arranged on the support platform 2 and on one side of the support frame 41. The length direction of the second linear module 51 is the same as the width direction of the lower housing 7. A carrier plate 54 is fixedly connected to the slider of the second linear module 51. The second Y-direction cylinder 53 is fixed on the carrier plate 54. A track 55 is arranged in the extending direction of the piston rod of the second Y-direction cylinder 53. A welding gun mounting block 56 is slidably arranged on the track 55. The piston rod of the second Y-direction cylinder 53 is connected to the welding gun mounting block 56.

[0053] A deep groove ball bearing 57 is arranged on both sides of the laser welding gun 52. Both of the two deep groove ball bearings 57 are used for pressing and movement guiding of the lower housing 7. A guide rod 58 is arranged on one side of the welding gun mounting block 56. One end of the guide rod 58 passes through the welding gun mounting block 56 and is movably connected thereto. The other end is located outside the welding gun mounting block 56 and is provided with a spring mounting block 59. A rectangular spring 510 is fixedly connected between the spring mounting block 59 and the outer wall of the welding gun mounting block 56. The rectangular spring 510 is sleeved on the outer wall of the guide rod 58. The piston rod of the second Y-direction cylinder 53 is fixedly connected to the spring mounting block 59.

[0054] The working principle of the welding tooling 4 is as follows: After the baffle 6 is loaded, the lower housing 7 workpiece is placed manually. After the placement is completed, the clamping cylinder 44 extends to drive the clamping plates 45 on both sides of the lower housing 7 workpiece to move inward, realizing the clamping of the lower housing 7 workpiece. The third cylinder 47 below the support frame 41 extends upward to cooperate with the limit hole on the support frame 41, realizing the rotational limit of the rotating tray 46, ensuring that the support frame 41 and the lower housing 7 and baffle 6 on the support frame 41 do not deflect during the welding process. After the lower housing 7 is clamped, the second linear module 51 drives the laser welding gun 52 to move to the specified position to the right, and then the second Y-direction cylinder 53 extends, making the laser welding gun 52 approach the lower housing 7 workpiece. The laser welding gun 52 is turned on and starts working. At the same time, the second linear module 51 moves to the right, thus realizing the welding of the lower housing 7 workpiece. The deep groove ball bearing 57 at the laser welding gun 52 realizes the pressing and movement guiding of the lower housing 7 workpiece during the welding process, while the rectangular spring 510 at the welding gun mounting plate is used to eliminate the dynamic adaptation in the case of uneven appearance of the lower housing 7 workpiece. After the welding of the lower housing 7 is completed, the second Y-direction cylinder 53 retracts, the second linear module 51 drives the laser welding gun 52 back to the origin, the third cylinder 47 retracts and returns to its original position, and the rotating tray 46 driven by the servo motor drives the lower housing 7 to rotate clockwise by 180°. After the rotation is in place, the third cylinder 47 extends, and the second linear module 51 drives the welding gun to complete the above welding process. After the welding is completed, the third cylinder 47 retracts and returns to its original position, the workpiece clamping plate is loosened, the laser welding gun 52 returns to the origin, the rotating tray 46 driven by the servo motor drives the lower housing 7 to rotate counterclockwise by 180°, and finally the welded lower housing 7 workpiece is removed manually.

[0055] In summary, the present invention proposes a welding device for the left and right baffles of the lower housing in a gas-filtering unit, aiming to solve the problems of time-consuming, laborious, and uncontrollable quality existing in traditional manual welding through automated and precise welding technology, improve production efficiency, and ensure the consistency and stability of product quality.
