Description

Technical Field

[0001] The present invention relates to the technical field of pressure sensor production, and in particular to a welding device for pressure sensor production and processing. Background Art

[0002] In the production process of pressure sensors, welding is a crucial process, which mainly connects the metal shell electrically and mechanically for packaging, ensuring airtightness or strengthening the structure to ensure the quality of the pressure sensor.

[0003] When welding the pressure sensor, the welding head is generally moved by a cylinder to make the welding head contact with the pressure sensor and weld the pressure sensor. During welding, a triangular chuck is needed to clamp the pressure sensor, and then the staff needs to manually unload the material after each welding is completed. This process not only consumes manpower and increases labor costs, but also generates high temperature during the welding process of the pressure sensor, causing the temperature of the pressure sensor to rise. Immediate manual unloading may cause burns to the staff. If forced air cooling, water cooling or natural cooling is used for rapid cooling after welding, it will cause a waste of resources, and the cooling process will take a certain amount of time, affecting the continuity of the operation and thus affecting work efficiency.

[0034] like Figure 6 , Fig. 9 and Fig.10 As shown, the pressing mechanism includes a guide plate 24, a sliding frame 25, a return spring 26, a pressure rod 27, a roller 28 and a push plate 29. The guide plate 24 is connected to the middle of the top of the box body 2 by bolts, and the sliding frame 25 is slidably connected to the bottom of the guide plate 24. The left and right parts of the sliding frame 25 are both sleeved with return springs 26, and the two ends of the return spring 26 are respectively connected to the guide plate 24 and the sliding frame 25.

[0035] like Figure 6 As shown, the rotating mechanism includes a spur gear 30 and a spur rack 31. The upper part of the rotating shaft 19 and the middle part of the pressure rod 27 are connected to the spur gear 30 through a key, and the upper and lower sides of the front side of the movable frame 16 are connected to the spur rack 31 through bolts. The spur rack 31 and the spur gear 30 have the same number of teeth. The spur rack 31 will mesh with the spur gear 30 during the process of moving to the left.

[0036] like Fig.11 As shown, it also includes a square block 32 and a positioning plate 33. The square block 32 is connected to the middle of the rotating shaft 19, and the left and right sides of the bottom of the spur gear 30 below are connected to the positioning plates 33 by bolts, and the front side of the left positioning plate 33 is in contact with the square block 32.

[0037] like Fig.12 As shown, it also includes a conveyor 34 and a baffle 35. The conveyors 34 are installed on both sides of the lower part of the box body 2 by bolts, and the top of the conveyor 34 is connected to the baffle 35.

[0038] like Fig.13 and Fig.14As shown, it also includes balls 37. An annular groove 36 is opened on the top of the mounting platform 18. The bottom of the circular box 20 is rotatably connected with balls 37 at uniform intervals in the circumferential direction. The balls 37 are located in the annular groove 36 and can roll along the annular groove 36.

[0039] like Figure 1 As shown, a box door 38 is also included. The left and right sides of the front side of the box body 2 are slidably connected with the box door 38. The box door 38 is made of transparent material to facilitate observation of the welding condition of the pressure sensor.

[0040] Initially, the pull plate 17 on the left is in contact with the left side of the contact block 10, the telescopic rod 7 on the left is in an extended state, the telescopic spring 9 on the left is in a stretched state, the telescopic rod 7 on the right is in a shortened state, and the telescopic spring 9 on the right is in a compressed state; the staff opens the box door 38, and then controls the screw motor 15 to drive the movable frame 16 and the pull plate 17 to move to the left, and the pull plate 17 on the left no longer pulls the contact block 10. Under the action of the telescopic spring 9, the sliding frame 8 moves to the left, and the sliding frame 8 drives the clamping plate 13 to move to the left, and moves the clamping plate 13 to the top of the circular box 20, and then turns off the screw motor 15. At this time, the telescopic rod 7 on the left is shortened and reset, and the telescopic rod 7 on the right is extended and reset. The staff then puts the pressure sensor on the cushion block 201. At this time, the pressure sensor position The box door 38 is then closed, and the output shaft of the servo motor 23 is controlled to rotate. The output shaft of the servo motor 23 drives the screw 21 on the left to rotate. The screw 21 on the left drives the other three screws 21 to rotate through the bevel gear. The screw 21 drives the four clamping blocks 22 to move in the direction of approaching each other to clamp the pressure sensor. The screw motor 15 is continued to control to drive the moving frame 16 to move to the left. The moving frame 16 drives the pull plate 17, the push plate 29 and the spur rack 31 to move to the left. The pull plate 17 on the left will be out of contact with the contact block 10, and the spur rack 31 will drive the positioning plate 33 to move to the left. The inclined part on the left side of the push plate 29 can push the roller 28 to move downward, and the roller 28 drives the sliding frame 25 to move downward. The reset spring 26 is stretched, and the sliding frame 25 moves downward. The movable frame 25 drives the pressure rod 27 to move downward, and the pressure rod 27 presses the pressure sensor on the cushion block 201 to improve the stability of the pressure sensor. The cushion block 201 can cushion the pressure sensor to prevent the pressure sensor from being damaged. The push plate 29, the spur rack 31 and the positioning plate 33 continue to move to the left, and the positioning plate 33 on the left will be out of contact with the square block 32, so that the square block 32 and the rotating shaft 19 can rotate. The spur rack 31 will mesh with the spur gear 30 during the process of moving to the left, and drive the spur gear 30 to rotate. The spur gear 30 drives the rotating shaft 19 and the pressure rod 27 to rotate, and the rotating shaft 19 drives the circular box 20 to rotate, thereby driving the pressure sensor on the cushion block 201 to rotate. The circular box 20 can also drive the ball 37 to rotate, and the ball 37 rolls in the annular groove 36 , the ball 37 can support the circular box 20 to prevent the circular box 20 from tilting. At the same time, the movable end of the electric push rod 4 is controlled to extend, driving the welding head 5 to move to the lower right, so that the welding head 5 is close to the welding position of the pressure sensor, and the welding head 5 welds the pressure sensor. Since the pressure sensor is rotating, the welding head 5 can fully weld the welding position of the pressure sensor. The spur rack 31 and the spur gear 30 have the same number of teeth, so the spur rack 31 just drives the spur gear 30 to rotate one circle, and the pressure sensor also just rotates one circle. After the spur rack 31 and the spur gear 30 are disengaged, the spur gear 30 stops rotating, and the pressure sensor also stops rotating. At this time, the pressure sensor has been welded, and the movable end of the electric push rod 4 can be controlled to shorten.The welding head 5 is driven to move to the upper left, so that the welding head 5 is away from the pressure sensor, and then the output shaft of the servo motor 23 is controlled to rotate in the opposite direction. The output shaft of the servo motor 23 drives the screw rod 21 on the left to rotate in the opposite direction. The screw rod 21 on the left drives the other three screw rods 21 to rotate in the opposite direction through the bevel gear. The screw rod 21 drives the four clamping blocks 22 to move away from each other, and the welded pressure sensor is released. The pulling plate 17, the pushing plate 29 and the positioning plate 33 continue to move to the left, and the inclined part on the right side of the pushing plate 29 gradually contacts with the roller 28. Under the action of the reset spring 26, the sliding frame 25 and the pressing rod 27 move upward, and the pressing rod 27 no longer presses the welded pressure sensor. Then the positioning plate 33 on the right contacts with the square block 32, and the positioning plate on the right 33 is used to position the square block 32, thereby positioning the clamping block 22, ensuring that the trajectories of the clamping block 22 and the pressure sensor moving left and right are staggered to avoid collision between the pressure sensor and the clamping block 22. At this time, the output shaft of the stepping motor 12 is controlled to rotate, driving the bidirectional screw rod 11 to rotate, and the bidirectional screw rod 11 drives the two clamping plates 13 to move in the direction of approaching each other, and the clamping plate 13 clamps the welded pressure sensor, and then the pull plate 17 on the right side will contact the contact block 10, and the pull plate 17 on the right side pulls the contact block 10 to the left, so that the contact block 10 moves to the left, and the contact block 10 drives the sliding frame 8 to move to the left, and the sliding frame 8 drives the clamping plate 13 to move to the left, thereby driving the welded pressure sensor to move to the left, automatically unloading, and improving work efficiency. When the welding is completed, the telescopic rod 7 on the left side will be shortened, the telescopic spring 9 on the left side will be compressed, the telescopic rod 7 on the right side will be extended, the telescopic spring 9 on the right side will be stretched, and the clamping plate 13 can clamp the welded pressure sensor to the top of the left conveyor 34, and control the output shaft of the stepping motor 12 to rotate in the opposite direction, driving the bidirectional screw rod 11 to rotate in the opposite direction, and the bidirectional screw rod 11 drives the two clamping plates 13 to move away from each other, so as to release the welded pressure sensor, and the welded pressure sensor will fall onto the conveyor 34 on the left side. The conveyor 34 on the left side transports the welded pressure sensor to the left, which is convenient for the staff to collect the welded pressure sensor, and can also transport the welded pressure sensor to the next process, thereby improving the continuity of the production process. The baffle plate 35 on the left can block the welded pressure sensor to prevent the welded pressure sensor from falling from the conveyor 34 on the left. At this time, the control screw motor 15 drives the moving frame 16 and the pull plate 17 to move to the right. The pull plate 17 on the right no longer pulls the contact block 10. Under the action of the telescopic spring 9, the sliding frame 8 moves to the right, and the sliding frame 8 drives the clamping plate 13 to move to the right. Move the clamping plate 13 to the top of the circular box 20, repeat the above operation, and continue to weld the pressure sensor. After the pressure sensor is welded, the clamping plate 13 can clamp the subsequent welded pressure sensor to the top of the conveyor 34 on the right side for unloading. The two conveyors 34 unload alternately, and the operation is more coherent, which can further improve work efficiency.
