Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a terminal bending and welding apparatus. Background Technology

[0002] Terminals are accessories used to achieve electrical connections and are a type of connector. They are widely used in industrial automation, electronic engineering, lighting, elevator control, instrumentation, power supply, chemical and automotive power fields. With the increasing level of industrial automation and the increasing requirements for industrial control, the usage of terminals is gradually rising.

[0003] Currently, terminals are mostly produced using a continuous die stamping method. When the tail end of the terminal is rolled, a gap exists between the bent tail end and the middle of the terminal. This gap needs to be welded. Existing welding technology mostly uses laser guns for welding. However, the terminals are small, and in order to ensure welding accuracy, workers need to first position the terminals and then use a laser gun to weld them. Positioning, welding, and collecting the finished products one by one is very time-consuming and reduces the efficiency of terminal welding.

[0004] In response to the aforementioned technologies, there is an urgent need to design and develop a terminal bending and welding device to facilitate automatic positioning, welding, and collection of finished terminals, thereby improving the welding efficiency of terminals. Summary of the Invention

[0005] To facilitate automatic positioning, welding, and collection of finished terminals and improve welding efficiency, this application provides a terminal bending and welding device.

[0006] The terminal bending and welding device provided in this application adopts the following technical solution:

[0007] A terminal bending and welding device includes a laser gun for welding the gaps of the bent portion of a terminal. The laser gun is mounted on a machine base, and the machine base is equipped with a control mechanism. The control mechanism includes a vibratory feeder for organizing the terminals, a conveying pipe for conveying the terminals from the vibratory feeder to below the laser gun, a positioning seat for fixing the terminals, a push block for pushing the terminals, a first collection frame for collecting finished terminals, a push rod for pushing the terminals toward the collection frame, and a baffle slidably disposed within the positioning seat. The vibratory feeder is mounted on the machine base, the conveying pipe is disposed beside the vibratory feeder, the positioning seat is disposed below the laser gun, and a snap-fit ​​groove is formed on the top surface of the positioning seat. The bent portion of the terminal can be snapped into the snap-fit ​​groove. The baffle is close to the snap-fit ​​groove. The push block is slidably disposed on the machine base and close to the output end of the conveying pipe. The push rod is slidably disposed on one side of the positioning seat, and the first collection frame is disposed on the other side of the positioning seat.

[0008] By adopting the above technical solution, the laser gun is set on the machine base, the vibratory feeder is set on the machine base, the conveying pipe is set next to the vibratory feeder, and the positioning seat is set below the laser gun. A snap-fit ​​groove is opened on the top surface of the positioning seat. The push block is slidably set on the machine base, close to the output end of the conveying pipe. The push rod is slidably set on one side of the positioning seat, and the baffle is slidably set inside the positioning seat, close to the snap-fit ​​groove. The first collection frame is set on the other side of the positioning seat. During the welding process, the vibratory feeder organizes the terminals and conveys them to the push block through the transmission pipe. The push block drives the terminals to slide to the push rod, and the push rod pushes the terminals onto the positioning seat, so that the bent part of the terminal slides into the snap-fit ​​groove and the terminal abuts against the baffle. At this time, the terminal is located below the laser gun. The laser gun welds the terminals. After welding, the sliding baffle is disengaged from the positioning seat, releasing the baffle from limiting the terminal. The push rod is driven again to push the terminal, so that the terminal is pushed into the first collection frame, which facilitates automatic positioning, welding and collection of finished terminals, and improves the welding efficiency of terminals.

[0009] Preferably, the gap at the terminal bend is located on the front side of the terminal bend, and a groove is formed on the back side of the terminal bend. A conveying and identification mechanism is provided on the machine base. The conveying and identification mechanism includes a first conveying bend connected to the outlet end of the vibratory feeder, a second conveying bend disposed beside the first conveying bend, an adapter pipe for conveying the terminal, a first mounting post disposed on the machine base, a first placement plate disposed on the first mounting post, and a photoelectric sensor for detecting the groove on the back side of the terminal bend. The second conveying bend is connected to the outlet end of the vibratory feeder, and the terminal is disposed on the... Between conveyor bend one and conveyor bend two, the adapter pipe is disposed on the machine base. The adapter pipe is close to conveyor bend one and conveyor bend two, and is connected to the conveying pipe. An observation groove is provided on the top surface of the adapter pipe. The terminal is slidably disposed in the adapter pipe, and the bent part of the terminal is disposed in the observation groove. Mounting post one is disposed next to the adapter pipe. The photoelectric sensor is disposed on the placement plate one, and the photoelectric sensor is located directly above the observation groove. The machine base is provided with a recycling mechanism for recycling terminals with the reverse side of the bent part facing up.

[0010] By adopting the above technical solution, the gap at the terminal bending part is located on the front side of the terminal bending part, and a groove is provided on the back side of the terminal bending part. Conveyor bending plate one is connected to the outlet end of the vibratory feeder, and conveyor bending plate two is also connected to the outlet end of the vibratory feeder. Conveyor bending plate two is positioned beside conveyor bending plate one, and the terminal is positioned between conveyor bending plate one and conveyor bending plate two.

An observation groove is provided on the top surface of the transfer pipe, and the terminal is slidably positioned within the transfer pipe, with the bending part of the terminal positioned within the observation groove. Mounting post one is positioned on the machine base, and mounting post one is positioned... Next to the transfer tube, a placement plate is set on the mounting column, and a photoelectric sensor is set on the placement plate. The photoelectric sensor is located directly above the observation slot. During the process of the vibratory feeder conveying the terminals, terminals in the appropriate position will be inserted between the first and second conveying plates and continue to be conveyed. Unsuitable terminals will fall back to the bottom of the vibratory feeder and return to the vibratory feeder for re-conveying. When the terminals are conveyed into the transfer tube, the photoelectric sensor detects whether there is a groove in the bent part of the terminal. If there is a groove, it means that this is the reverse side of the bent part of the terminal that does not need to be welded. The terminal with the reverse side of the bent part on the top can be retrieved by the recycling mechanism, which is convenient for subsequent welding of the terminal.

[0011] Preferably, the adapter tube has a through hole one on its side, which is connected to the top surface of the adapter tube, and a through hole two on its side, which is connected to the through hole one.

A second collection frame is set on the machine base, and a recovery pipe is set next to the adapter tube, close to the second collection frame, and connected to the through hole 1. An air gun is set on the machine base, and the output end of the air gun is set in the through hole 2. A protective block is vertically slidably set in the through hole 1. When the photoelectric sensor detects a groove in the terminal inside the adapter tube, the control mechanism controls the protective block to disengage from the through hole 1, releasing the protection of the terminal by the protective plate. The air gun blows the terminal, and the terminal slides from the adapter tube through the through hole 1 to the recovery pipe, and then slides into the second collection frame through the recovery pipe, which facilitates the recovery of the terminal with the bent part facing up.

When it is necessary to drive the protective block to slide vertically, the drive motor one drives the mounting column two to rotate in the forward direction. Through the connection relationship of mounting column two, swing rod, and contact rod, the connecting rod is driven to slide towards the inclined surface of the inclined block. Under the elastic force of the spring, the sliding plate drives the protective block to move upward and disengage from the through hole one. The drive motor one drives the mounting column two to rotate in the reverse direction, so that the connecting rod slides away from the inclined surface of the inclined block and slides towards the top surface of the sliding plate.

The push rod is then driven again to push the terminals, causing them to be pushed into the first collection frame. This facilitates automatic positioning, welding, and collection of finished terminals without manual operation, making it convenient, fast, and improving the welding efficiency of the terminals.

Unsuitable terminals will fall back to the bottom of the vibratory feeder and return to the vibratory feeder for re-conveying. When the terminals are conveyed into the transfer tube, the photoelectric sensor detects whether there is a groove in the bent part of the terminal. If there is a groove, it means that this is the reverse side of the bent part of the terminal that does not need to be welded.

[0041] The present application will be further described in detail below with reference to the accompanying drawings.

[0042] This application discloses a terminal bending and welding apparatus. (Refer to...)

The vibratory plate 31 is mounted on the machine base 1, and the conveying pipe 32 is mounted next to the vibratory plate 31. The length direction of the conveying pipe 32 is parallel to the ground.

[0045] Reference Figure 1 and Figure 2 As shown, the positioning seat 33 is located below the laser gun 2. A snap-fit ​​groove 331 is provided on the top surface of the positioning seat 33. The push block 34 is slidably mounted on the machine base 1. The push block 34 is close to the output end of the conveying pipe 32. The push rod 36 is slidably mounted on one side of the positioning seat 33. The baffle 37 is slidably mounted inside the positioning seat 33. The baffle 37 is close to the snap-fit ​​groove 331. The first collection frame 35 is located on the other side of the positioning seat 33.

[0046] Reference Figure 1 , Figure 2 and Figure 3 As shown, during the welding process of terminal 12, the vibratory plate 31 organizes terminal 12 and transmits terminal 12 to push block 34 via transmission pipe. Push block 34 drives terminal 12 to slide to push rod 36. Push rod 36 pushes terminal 12 to positioning seat 33, so that the bent part of terminal 12 slides into the snap-fit ​​groove 331 and terminal 12 abuts against baffle 37. At this time, terminal 12 is located below laser gun 2. Laser gun 2 welds terminal 12. After welding is completed, sliding baffle 37 disengages from positioning seat 33, releasing the baffle 37 from limiting terminal 12. Push rod 36 is driven again to push terminal 12, so that terminal 12 is pushed into first collection frame 35, which facilitates automatic positioning, welding and collection of finished terminal 12, and improves the welding efficiency of terminal 12.

[0047] Reference Figure 1 , Figure 3 and Figure 4 As shown, the gap at the bend of terminal 12 is located on the front side of the bend of terminal 12, and a groove 121 is provided on the back side of the bend of terminal 12. The conveying and identification mechanism 4 includes a first conveying bend 41, a second conveying bend 42, a transfer tube 43, a first mounting post 44, a first placement plate 45, and a photoelectric sensor 46.

The unsuitable terminal 12 will fall back to the bottom of the vibratory feeder 31 and return to the vibratory feeder 31 for re-conveying. When the terminal 12 is conveyed into the transfer tube 43, the photoelectric sensor 46 detects whether there is a groove 121 in the bent part of the terminal 12. If there is a groove 121, it means that this is the reverse side of the bent part of the terminal 12 that does not need to be welded.

The bottom end of spring 67 abuts against the top surface of adapter pipe 43, and the top end of spring 67 abuts against the bottom surface of sliding plate 61. When it is necessary to drive the protective block 54 to slide vertically, drive motor 63 drives mounting post 64 to rotate in the forward direction. Through the connection relationship of mounting post 64, swing rod 65, and abutment rod 66, the connecting rod is driven to slide towards the inclined surface of inclined block 62. Under the elastic force of the spring, sliding plate 61 drives the protective block 54 to move upward and disengage from through hole 432.

[0064] Reference Figure 1 , Figure 2 and Figure 8 As shown, the sensing mechanism 9 includes a mounting block 91, a sliding plate 92, a touch switch 93, an abutment block 94, and a spring 95.

A sliding groove 911 is provided on the side of the mounting block 91, and a sliding groove 912 is provided on the top wall of the sliding groove 911.

[0066] Reference Figure 1 , Figure 2 and Figure 8 As shown, during the process of the transmission pipe 32 transmitting the terminal 12 to the push block 34, the terminal 12 presses against the slide plate 92. When the slide plate 92 drives the abutment block 94 to abut against the touch switch 93, it indicates that the terminal 12 has been completely pushed onto the push block 34. Then, the control vibratory plate 31 stops transmitting the terminal 12, and the drive cylinder 82 drives the push block 34 to transmit the terminal 12 to the end of the push rod 36. At this time, the push plate 39 abuts against the slide plate 92.

[0067] Reference Figure 1 , Figure 2 and Figure 8 As shown, when the welding of terminal 12 is completed, the push rod 36 pushes terminal 12 into the first collection frame 35. The drive cylinder 82 drives the push block 34 and push plate 39 away from the slide plate 92. When the push plate 39 is no longer in contact with the slide plate 92, the contact block 94 releases its contact with the touch switch 93. Then the vibratory plate 31 continues to convey terminal 12, which facilitates the welding of terminal 12 in sequence and ensures that the welding work is carried out in an orderly manner.

[0068] Reference Figure 1 and Figure 2 As shown, a screw 10 is provided on the conveying pipe 32, and a clamping wire 101 is wound on the screw 10 to abut against the straight plate on the front side of the terminal 12, thereby improving the stability of the terminal 12 being conveyed from the conveying pipe 32 to the push block 34.

[0069] The implementation principle of the terminal 12 bending and welding device in this application embodiment is as follows:

[0070] During the welding process of terminal 12, the vibratory feeder 31 organizes terminal 12 and transmits terminal 12 to push block 34 through transmission pipe. Push block 34 drives terminal 12 to slide to push rod 36. Push rod 36 pushes terminal 12 to positioning seat 33, so that the bent part of terminal 12 slides into the snap-fit ​​groove 331 and terminal 12 abuts against baffle 37. At this time, terminal 12 is located below laser gun 2. Laser gun 2 welds terminal 12. After welding is completed, sliding baffle 37 disengages from positioning seat 33, releasing the baffle 37 from limiting terminal 12. Push rod 36 is driven again to push terminal 12, so that terminal 12 is pushed into first collection frame 35. This facilitates automatic positioning, welding and collection of finished terminal 12 without manual operation, which is convenient and fast and improves the welding efficiency of terminal 12.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
