[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0032] See also Figure 1 - Fig. 9As shown, a silver contact welding device comprises a device body 1, on which a fixed seat 20 and a movable seat 21 are fixedly connected, and a clamping rod 61 is fixedly connected to both the fixed seat 20 and the movable seat 21, and the top of the clamping rod 61 is located directly above the silver contact body 22, and the silver contact body 22 is close to the induction coil 23, and the rear end of the induction coil 23 is connected to a power supply, and a pushing mechanism is arranged at the rear end of the silver contact body 22, and the pushing mechanism is used for the pusher plate 41 to push the silver contact body 22 forward when the movable seat 21 is lifted upward so as to remove the silver contact body 22, and a lifting mechanism is arranged below the silver contact body 22, and the lifting mechanism is used for lifting the silver contact body 22 to prevent the silver contact body 22 from being located inside the induction coil 23 so that the silver contact body 22 cannot be normally pushed by the pusher plate 41, and a collecting mechanism is arranged at the front end of the fixed seat 20, and the collecting mechanism is used for collecting the pushed silver contact body 22;

[0033] Further, the pushing mechanism includes a connecting rod 24, the top of which is fixedly connected to the left side of the moving seat 21, the bottom of which is rotatably connected to a pushing rod 25, the bottom of which is rotatably connected to a disc 26, the right side of which is fixedly connected to a transmission shaft 35, the transmission shaft 35 is rotatably connected to a support rod 33, the bottom end of which is fixedly connected to the device body 1, the right side of which is fixedly connected to a driving wheel 36, the driving wheel 36 is rotatably connected to the inside of the fixed seat 20, and a belt 37 is sleeved on the driving wheel 36. The side of the belt 37 away from the driving wheel 36 is sleeved on the driven wheel 38, and the driven wheel 38 is fixedly connected to the driving gear 39. The driven wheel 38 and the driving gear 39 are both rotatably connected to the rear end of the fixed seat 20. The driving gear 39 is meshed with the fixed gear 40. The fixed gear 40 is fixedly connected to the bottom end of the push plate 41. The left and right sides of the push plate 41 are fixedly connected with sliders 43. The sliders 43 are slidably connected to the side plates 42. The side plates 42 are fixedly connected to the device body 1. The side plates 42 are provided with movable grooves corresponding to the sliders 43, and the push plate 41 is provided with through holes;

[0034] Through the structural design of the pushing mechanism, after welding is completed, the movable seat 21 will be lifted upward, and at this time, the pushing plate 41 will rotate a certain angle and push the silver contact body 22 forward, so that the silver contact body 22 can be quickly removed after welding is completed, making the material removal process more convenient. When working, the silver contact body 22 is first placed on the two sets of clamping rods 61 on the fixed seat 20, and the connecting rod 24 will move downward under the drive of the cylinder, so that the silver contact body 22 is clamped by the clamping rods 61 on the fixed seat 20 and the movable seat 21 during welding. The induction coil 23 then heats the silver contact body 22 to complete the welding. At this time, the cylinder drives the moving seat 21 to move upward again. In this process, the connecting rod 24 connected to one side of the moving seat 21 pulls the push rod 25. The push rod 25 is rotatably connected to the disc 26. Therefore, the push rod 25 pulls the disc 26 to rotate. During the rotation of the disc 26, the rotation is transmitted to the driving wheel 36 through the transmission shaft 35. The driving wheel 36 and the driven wheel 38 are provided with a belt 37. Therefore, the driven wheel 38 can rotate synchronously with the driving wheel 36. The driven wheel 38 is connected to the driving gear 39, and the driving gear 39 drives the fixed gear 40 to rotate by meshing with the fixed gear 40. Due to the design of the driving gear 39, the driving gear 39 can only drive the fixed gear 40 to rotate a certain angle to avoid the fixed gear 40 rotating too much, which will cause the push plate 41 to abut against the rear end of the fixed seat 20. The fixed gear 40 is fixed to the bottom end of the push plate 41, and the sliders 43 fixed on the left and right sides of the push plate 41 will slide on the side plate 42. The side plate 42 is provided with a movable groove corresponding to the slider 43. 43 can provide support for the rotation of the push plate 41. The top of the push plate 41 is designed in an L shape to facilitate pushing the silver contact body 22. At this time, the top of the push plate 41 will move to a position close to the silver contact body 22, and finally push the silver contact body 22 down. Similarly, when the moving seat 21 starts to move downward from the top position, the driving gear 39 will be disengaged from the fixed gear 40, and the push plate 41 can be rotated to the original position at this time to avoid interference with the silver contact body 22 during welding. A through hole is opened near the top of the push plate 41. So that when the push plate 41 rotates, it will not abut against the induction coil 23, and the rear end of the induction coil 23 can smoothly pass through the push plate 41 and connect to the power supply.

[0035] Further, the lifting mechanism includes a lifting rod 59, the top of which is T-shaped, the top of which contacts the bottom of the silver contact body 22, the bottom of which is fixedly connected with a connecting block 58, the connecting block 58 is L-shaped, the bottom of which is fixedly connected with an abutting rod 57, the bottom of which is provided with a rounded corner, the bottom of which abuts against a cam 55, the cam 55 being located on the right side of the connecting plate 50, the cam 55 being fixedly connected with the driving wheel 36, and the cam 55 being rotatably connected to the inside of the fixing seat 20;

[0036] Through the structural design of the lifting mechanism, when the movable seat 21 is lifted upward, the lifting rod 59 will move upward to drive the silver contact body 22 to move upward synchronously, so that the bottom end height of the silver contact body 22 can be higher than the top end height of the induction coil 23, and the silver contact body 22 can extend from the inside of the induction coil 23. At this time, when the push plate 41 rotates, it can smoothly abut against the silver contact body 22 and smoothly push the silver contact body 22 off the lifting rod 59. During operation, when the driving wheel 36 rotates inside the fixed seat 20, the cam 55 connected to the driving wheel 36 will rotate synchronously. During the rotation process, the cam 55 will gradually push the abutment rod 57 upward, and the top end of the abutment rod 57 is connected to the lifting rod 59 through the connecting block 58. , so the lifting rod 59 can move upward, and at this time the lifting rod 59 will drive the silver contact body 22 to move upward, so as to extend the silver contact body 22 from the inside of the induction coil 23, wherein the bottom end of the abutting rod 57 is provided with a rounded corner to facilitate smoother abutment with the cam 55, and the connecting block 58 is designed in an L shape to connect the bottom end of the lifting rod 59 and the abutting rod 57, and the connecting block 58 slides inside the fixed seat 20. Through the design of the connecting block 58, the lifting rod 59 can be located in the middle position of the fixed seat 20, so as to better drive the silver contact body 22 to move, and the top end of the lifting rod 59 is designed in a T shape, which can increase the contact area with the bottom end of the silver contact body 22, so that the silver contact body 22 can be stably placed on the lifting rod 59.

[0037] Further, the collecting mechanism includes a baffle 51, the baffle 51 is located at the bottom end of the blanking box 52, the blanking box 52 is fixedly connected to the front end of the fixed seat 20, the rear end of the baffle 51 is fixedly connected to the connecting plate 50, the rear end of the connecting plate 50 is fixedly connected to the rack 48, the rack 48 is meshed with the fixed gear 40, the rack 48 is slidably connected to the mounting plate 54, the mounting plate 54 is fixedly connected to the fixing plate 53, the fixing plate 53 is fixedly connected to the two sets of side plates 42, and the rear end of the rack 48 is provided with a reset mechanism;

[0038] Through the structural design of the collecting mechanism, the silver contact body 22 is pushed forward by the pushing plate 41, and a blanking box 52 is fixed at the front end of the fixed seat 20, and the blanking box 52 can collect the silver contact body 22, and when the pushing plate 41 pushes the silver contact body 22 forward, the baffle 51 will slide at the bottom of the blanking box 52, so that the bottom end of the blanking box 52 is connected with the outside world. At this time, the silver contact body 22 dropped into the blanking box 52 can be uniformly dropped out from the bottom end of the blanking box 52, so as to facilitate the collection of the silver contact body 22. When working, the fixed gear 40 is meshed with the rack 48. Therefore, when the fixed gear 40 rotates, the rack 48 will 54, the front end of the rack 48 is connected to the baffle 51 through the connecting plate 50, the rack 48 and the connecting plate 50 both slide inside the fixed seat 20, and the baffle 51 moves with the connecting plate 50, and the baffle 51 will be away from the bottom end of the drop box 52, and the bottom end of the drop box 52 was originally blocked by the baffle 51. At this time, the bottom end of the drop box 52 will be connected to the outside world. At this time, the silver contact body 22 that falls into the drop box 52 can fall out from just below the drop box 52, so that the dropped device body 1 can be uniformly collected through the drop box 52 to avoid the silver contact body 22 being scattered to various positions of the device body 1, which will cause trouble for subsequent collection.

[0039] Further, the reset mechanism includes a push rod 46, which is fixedly connected to the rear end of the rack 48, and a reset spring 47 is sleeved on the push rod 46. The front and rear sides of the reset spring 47 are respectively fixedly connected to the rack 48 and the inner wall of the mounting plate 54.

The bottom end of the sleeve 45 is fixedly connected to the fixing plate 53. The sleeve 45 is provided with an exhaust hole 44 near the rear end, and the exhaust hole 44 is connected to the inside of the sleeve 45.

[0040] During operation, when the fixed gear 40 rotates to drive the rack 48 to slide on the mounting plate 54, the return spring 47 fixed on the rear end of the rack 48 will be compressed. When the driving gear 39 is not engaged with the fixed gear 40, the return spring 47 can push the rack 48 to move in the reverse direction, thereby driving the fixed gear 40 to rotate in the reverse direction to reset the push plate 41. In order to prevent the return spring 47 from driving the rack 48 to move back and forth, the rear end of the push rod 46 is inserted into the sleeve 45. When the rack 48 moves, the push rod 46 will also slide inside the sleeve 45. The movement of the push rod 46 will squeeze the air inside the sleeve 45, thereby achieving a damping effect. An exhaust hole 44 is provided on the sleeve 45 to ensure that the interior of the sleeve 45 can be normally connected to the outside world.

[0041] Furthermore, a groove 49 is formed on the connecting plate 50, and the groove 49 is U-shaped;

[0042] During operation, the groove 49 is U-shaped, and the connecting plate 50 is located between the driving wheel 36 and the cam 55. The design of the groove 49 can ensure that when the connecting plate 50 slides inside the fixing seat 20, it will not affect the normal rotation of the shaft connecting the driving wheel 36 and the cam 55.

[0043] Furthermore, an extension column 60 is fixedly connected to the middle of the top of the fixing seat 20, and the extension column 60 is sleeved on the outer side of the lifting rod 59;

[0044] During operation, the extension column 60 is sleeved on the lifting rod 59, and can guide the bottom end of the lifting rod 59 when the lifting rod 59 moves, so as to ensure that the lifting rod 59 can move stably in the vertical direction and reduce the shaking of the lifting rod 59 when moving.

[0045] Furthermore, the disc 26 abuts against four groups of rollers 29, and the rollers 29 are rotatably connected to the inner wall of the support plate 32, and the bottom end of the support plate 32 is fixedly connected to the device body 1;

[0046] During operation, the four groups of rollers 29 rotate on the support plate 32 , and can provide support to the disc 26 when the disc 26 rotates, so as to facilitate the stable rotation of the disc 26 . Example

However, when the disc 26 rotates in the opposite direction, the top block 30 will abut against the inner wall of the rectangular groove 27, thereby ensuring that the disc 26 can only rotate in the same direction.

[0049] The rear end of the push rod 46 is T-shaped, and a washer 56 is sleeved on the rear end of the push rod 46. The washer 56 is made of rubber and fits the inner wall of the sleeve 45.
