Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding machines, in particular to a welding machine for contacts and silver points. Background Technique
[0002] A circuit breaker is a combined switch that can cut off the circuit to protect it when a circuit failure occurs. In the electromagnetic system of the circuit breaker, there are movable and static contacts for circuit connection or disconnection. During the processing of the movable and static contacts, silver points with good electrical conductivity need to be welded onto them. In order to improve the welding and assembly efficiency, through continuous research and development by technicians in this field, processing equipment for automatically welding contacts and silver points has emerged on the market.
[0003] In the existing patent, the Chinese patent document with the application number 202120027720.2 discloses an automatic welding device for contact silver points, including a contact displacement device, a contact feeding device, a flux dropping device, a silver point feeding device, and a welding execution device. The contact displacement device has several stations for placing contacts, and the contact displacement device moves the contact at the previous station to the next station at intervals. The stations include a contact feeding station, a flux dropping station, a silver point feeding station, and a welding execution station. The contact feeding device, the flux dropping device, the silver point feeding device, and the welding execution device are sequentially arranged at the contact feeding station, the flux dropping station, the silver point feeding station, and the welding execution station of the contact displacement device respectively; the contact feeding device is located at the feeding end of the contact displacement device and feeds contacts to the contact feeding station, the flux dropping device drops flux onto the corresponding position of the contact at the flux dropping station, the silver point feeding device places silver points on the position of the contact at the silver point feeding station where flux is dropped, the welding execution device is located at the discharging end of the contact displacement device and performs a welding action on the contact at the welding execution station; the contact displacement device includes a contact sliding channel, several jaw cylinders, and a translation moving module. The feeding port of the contact sliding channel communicates with the discharging position of the contact feeding device, and each station is located on the contact sliding channel. The jaw cylinders are fixed on the output shaft of the translation moving module and the jaw cylinders clamp the contact at the station and move it to the next station; the welding execution device includes a discharging mechanism, a lower welding head, and an upper welding head that can move up and down. The lower welding head is located at the welding execution station and receives the incoming material clamped by the jaw cylinders, and the upper welding head descends to perform a welding action on the incoming material with the lower welding head.
[0004] This patent document realizes the welding of the contact and the silver point by pressing the contact and the silver point tightly with the upper welding head and the lower welding head. The upper welding head acts directly on the silver point, which is likely to cause the silver point to turn black during the welding process, resulting in poor welding quality.

[0028] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present utility model.
[0029] As Figures 1 to 7As shown in the figure, a contact and silver point welding machine provided by the present utility model includes a machine table 1, a welding fixture 2 installed on the machine table 1, two resistance welding mechanisms 3 installed on the machine table 1 and relatively movably arranged on both sides of the welding fixture 2, a contact supply device 4 and a silver point supply device 5 respectively installed on the machine table 1, a contact transfer mechanism 6 movably arranged between the discharge end of the contact supply device 4 and the welding fixture 2, a soldering tin coating mechanism 7 installed on the machine table 1 and erected above the contact transfer mechanism 6, a silver point transfer mechanism 8 movably arranged between the discharge end of the silver point supply device 5 and the welding fixture 2, a contact and silver point positioning device 9 movably arranged above the welding fixture 2, and a blanking device 10 installed on the machine table 1. The two resistance welding mechanisms 3 are used to apply pressure and conduct electricity to both sides of the contact carried by the welding fixture 2. Specifically, both the contact transfer mechanism 6 and the blanking device 10 can adopt clamping manipulators, and the silver point transfer mechanism 8 can adopt a suction cup manipulator. The silver point transfer mechanism 8 is located between the contact supply device 4 and the welding fixture 2. The feeding direction of the contact supply device 4 is perpendicular to the feeding direction of the silver point supply device 5. The silver point supply device 5 is located on one side of one of the resistance welding mechanisms 3 away from the welding fixture 2.
[0030] In practical applications, the contact supply device 4 supplies contacts. The soldering tin coating mechanism 7 coats soldering tin on the welding part of the contacts supplied by the contact supply device 4. Then the contact transfer mechanism 6 picks up the contacts coated with soldering tin and places them on the welding fixture 2. At the same time, the silver point supply device 5 supplies silver points. The silver point transfer mechanism 8 picks up the silver points supplied by the silver point supply device 5 and places the silver points on the soldering tin of the welding part of the contacts carried by the welding fixture 2. Then the contact and silver point positioning device 9 positions the contacts on the welding fixture 2 and the silver points on the contacts. Then the two resistance welding mechanisms 3 approach each other until the electrodes of the two resistance welding mechanisms 3 apply pressure and conduct electricity to both sides of the contact respectively, so as to weld the silver points on the welding part of the contact. Finally, the blanking device 10 takes away the contacts welded with silver points from the welding fixture 2 and conducts blanking for them. The present utility model automatically completes the welding of contacts and silver points, and the electrodes of the two resistance welding mechanisms 3 apply pressure and conduct electricity to both sides of the contact to complete the welding, avoiding the phenomenon that the resistance welding mechanism 3 directly acts on the silver points, which easily causes the silver points to turn black, and ensuring the welding quality of contacts and silver points.
[0031] In this embodiment, the machine table 1 is provided with a blanking channel 11. The blanking channel 11 is located below the blanking device 10. The blanking device 10 is movably arranged between the blanking channel 11 and the welding fixture 2. In practical applications, the blanking device 10 takes away the contacts welded with silver points carried by the welding fixture 2 and places them at the blanking channel 11. The blanking channel 11 conveys the contacts welded with silver points to the required position to realize automatic blanking.
[0032] In this embodiment, the contact silver point positioning device 9 includes a support frame 12 installed on the machine table 1, a lifting drive mechanism 13 provided at the top of the support frame 12, a lifting block 14 installed at the lifting end of the lifting drive mechanism 13, a contact pressing rod 15 installed on the lifting block 14, a lifting driver 16 installed on the lifting block 14, and a silver point pressing rod 17 installed at the lifting end of the lifting driver 16. The contact pressing rod 15 is used to press the contact tightly on the welding jig 2, and the silver point pressing rod 17 is used to press the silver point tightly on the contact. Specifically, both the lifting drive mechanism 13 and the lifting driver 16 can adopt air cylinders, and both the contact pressing rod 15 and the silver point pressing rod 17 are insulating and heat-insulating rods.
[0033] In practical applications, after the silver point is placed on the welding part of the contact carried by the welding jig 2, the lifting drive mechanism 13 drives the lifting block 14 to move downward, so that the contact pressing rod 15 presses the contact on the welding jig 2. Then, the lifting driver 16 drives the silver point pressing rod 17 to move downward, so that the silver point pressing rod 17 presses the silver point on the welding part of the contact, so as to realize the pressing and positioning of the contact and the silver point.
[0034] In this embodiment, the contact silver point positioning device 9 further includes a silver point positioning mechanism 18 installed on the lifting block 14. The silver point positioning mechanism 18 includes a positioning lifter 19 installed on the lifting block 14, a finger cylinder 20 installed at the lifting end of the positioning lifter 19, and two positioning blocks 21 respectively installed at the two output ends of the finger cylinder 20. The finger cylinder 20 is used to drive the two positioning blocks 21 to approach or move away from each other, and the two positioning blocks 21 are used to position the silver point on the contact. Specifically, the positioning lifter 19 can adopt an air cylinder. In practical applications, before the silver point pressing rod 17 presses the silver point on the welding part of the contact, the positioning lifter 19 drives the finger cylinder 20 and the two positioning blocks 21 to descend, so that the silver point is located between the two positioning blocks 21. Then, the finger cylinder 20 drives the two positioning blocks 21 to approach each other until the two positioning blocks 21 clamp and position the silver point. Finally, the silver point pressing rod 17 moves downward and presses the positioned silver point on the welding part of the contact, so as to improve the position accuracy and stability of the silver point on the contact.
[0035] In this embodiment, the contact silver point positioning device 9 further includes a moving seat 22 slidably connected to the top of the support frame 12, a translation drive mechanism 23 installed on the support frame 12 and used to drive the moving seat 22 to translate, and a first visual positioning mechanism 24 installed on the moving seat 22. The lifting drive mechanism 13 is installed on the moving seat 22, and the first visual positioning mechanism 24 is electrically connected to the silver point transfer mechanism 8. Specifically, the translation drive mechanism 23 can adopt an air cylinder.
[0036] In practical applications, the translation drive mechanism 23 drives the moving seat 22 to drive the lifting drive mechanism 13 and the first vision positioning mechanism 24 to reciprocate translationally. During the reciprocating translation process, not only can the working of the contact silver point positioning device 9 be avoided from interfering with the silver point transfer mechanism 8, the contact transfer mechanism 6, and the blanking device 10, but also after the first vision positioning mechanism 24 performs vision positioning on the contacts on the welding jig 2, the silver point transfer mechanism 8 can be controlled to accurately place the silver points on the welding parts of the contacts.
[0037] In this embodiment, a temperature detector 25 is installed on the support frame 12. The temperature detector 25 is used to monitor the temperature of the contacts carried by the welding jig 2. Specifically, the temperature detector 25 can be an infrared temperature detector. In practical applications, the temperature detector 25 monitors the welding temperature of the contacts to ensure that the welding temperature is within the preset temperature range, thereby ensuring the welding quality.
[0038] In this embodiment, the contact supply device 4 includes a contact vibrating disk 26 installed on the machine table 1, a contact material rail 27 connected to the discharge port of the contact vibrating disk 26, a contact linear vibrating feeder 28 installed on the machine table 1 and arranged below the contact material rail 27, and a contact discharge positioning mechanism 29 arranged at the discharge end of the contact material rail 27. In practical applications, the contact vibrating disk 26 conveys the contacts onto the contact material rail 27. Under the action of the contact linear vibrating feeder 28, the contacts move along the contact material rail 27 and move to the contact discharge positioning mechanism 29. The contact discharge positioning mechanism 29 positions the contacts to ensure the accuracy of the solder coating mechanism 7 for coating solder on the contacts and the accuracy of the contact transfer mechanism 6 for picking up the contacts.
[0039] In this embodiment, the contact discharge positioning mechanism 29 includes a contact positioning seat 30 for connecting with the discharge port of the contact material rail 27, a discharge lifter 31 installed on the machine table 1 and used to drive the contact positioning seat 30 to lift, and a side pusher 32 installed on the contact positioning seat 30. The contact positioning seat 30 is provided with a contact loading cavity 33. The side pusher 32 is located on one side of the contact loading cavity 33. The solder coating mechanism 7 is arranged opposite to the contact loading cavity 33. The contact transfer mechanism 6 is movably arranged between the solder coating mechanism 7 and the contact positioning seat 30. Specifically, the side pusher 32 can be a horizontally arranged cylinder, and the discharge lifter 31 can be a vertically upward arranged cylinder.
[0040] In practical applications, the contacts on the contact rail 27 move into the contact carrier cavity 33 of the contact positioning seat 30. The side pusher 32 laterally pushes the contacts so that the contacts are positioned within the contact carrier cavity 33. Then, the discharging elevator 31 drives the contact positioning seat 30 to rise together with the contacts to achieve the discharging of the contacts, facilitating the soldering tin application mechanism 7 to apply soldering tin to the contacts and the contact transfer mechanism 6 to transfer the contacts; during the rising process of the contact positioning seat 30, the contact positioning seat 30 blocks the discharging port of the contact rail 27 to ensure the stability of the contact supply.
[0041] In this embodiment, the silver dot device 5 includes a silver dot vibrating bowl 34 installed on the machine table 1, a silver dot rail 35 connected to the discharging port of the silver dot vibrating bowl 34, a silver dot linear vibrating feeder 36 installed on the machine table 1 and disposed below the silver dot rail 35, a silver dot discharging positioning mechanism 37 disposed at the discharging end of the silver dot rail 35, and a second vision positioning mechanism 38 installed on the machine table 1 and erected above the silver dot discharging positioning mechanism 37. The second vision positioning mechanism 38 is electrically connected to the silver dot transfer mechanism 8.
[0042] In practical applications, the silver dot vibrating bowl 34 supplies silver dots to the silver dot rail 35. Under the action of the silver dot linear vibrating feeder 36, the silver dots move along the silver dot rail 35 and move to the silver dot discharging positioning mechanism 37. The silver dot discharging positioning mechanism 37 positions the silver dots, and the second vision positioning mechanism 38 performs vision positioning on the silver dots at the silver dot discharging positioning mechanism 37 and controls the action of the silver dot transfer mechanism 8 so that the silver dot transfer mechanism 8 can accurately pick up the silver dots.
[0043] In this embodiment, the silver dot discharging positioning mechanism 37 includes a silver dot receiving seat 39 connected to the discharging port of the silver dot rail 35, a push block 40 slidably connected to the silver dot receiving seat 39, and a moving driver 41 installed on the silver dot receiving seat 39 and used to drive the push block 40 to reciprocate. The silver dot receiving seat 39 is recessed with a receiving channel 42 communicating with the discharging port of the silver dot rail 35 and a discharging channel 43 vertically communicating with the receiving channel 42. The push block 40 is used to push the silver dots in the receiving channel 42 into the discharging channel 43; specifically, the moving driver 41 can adopt a cylinder.
[0044] In practical applications, the silver dot rail 35 transports the silver dots into the receiving channel 42. When the silver dots in the receiving channel 42 are aligned with the push block 40 and the discharging channel 43, the moving driver 41 drives the push block 40 to move, so that the push block 40 pushes the silver dots in the receiving channel 42 into the discharging channel 43 to achieve the stable discharging of the silver dots.
[0045] All the technical features in this embodiment can be freely combined according to actual needs.
[0046] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
