Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to an automatic continuous multi-point welding system. Background Art

[0002] With the continuous development of society and economy and the increasing level of science and technology, my country's automobile industry is also booming. As a component used to connect circuits within the car, automotive connectors can build a bridge between blocked or isolated circuits within the circuit, thereby allowing current to flow and enabling the circuit to achieve its intended function. In the process of producing automotive connectors, it is usually necessary to use welding equipment to solder the end of the automotive connector.

[0003] In the prior art, there is an automatic continuous multi-point welding system, which includes a machine body, a processing table of the machine body is provided with a jig for welding, and the jig is provided with a number of automobile connectors to be welded. The machine body is also provided with a movable frame, a movable mechanism, a lifting cylinder and an electric soldering iron, and the movable mechanism is used to drive the movable frame to move along the distribution direction of the automobile connectors on the jig. The lifting cylinder is provided on the movable frame and is used to drive the electric soldering iron to move up and down, so that the soldering iron tip at the bottom of the electric soldering iron contacts the part to be welded on the automobile connector. When in use, the movable mechanism drives the movable frame to move above the automobile connector to be welded, and then the lifting cylinder drives the electric soldering iron downward, so that the soldering iron tip on the electric soldering iron contacts the part to be welded on the automobile connector, so that the electric soldering iron performs welding.

[0004] Regarding the above-mentioned related technologies, since the soldering iron tip on the electric soldering iron needs to be against the automotive connector during each welding process of the automotive connector, as the processing time accumulates, the end of the soldering iron tip is prone to wear during the collision and extrusion with the surface of the automotive connector. Since the stroke of the lifting cylinder is fixed, the worn soldering iron tip is prone to gaps in the contact area with the automotive connector, resulting in difficulty in the worn soldering iron tip to fully contact the automotive connector, thereby reducing the welding effect, so it needs to be improved. Summary of the Invention

The adjusting member is used to drive the electric soldering iron to move, and the moving direction of the electric soldering iron is the same as the lifting direction of the lifting frame, so that the soldering iron tip on the electric soldering iron abuts against the part to be soldered on the automotive connector.

[0007] By adopting the above technical solution, compared with the prior art, the electric soldering iron is completely driven by the lifting cylinder, which makes it easy for a gap to appear in the contact part of the worn soldering iron tip and the automobile connector, resulting in difficulty in the worn soldering iron tip to fully contact the automobile connector, thereby reducing the welding effect; the present application arranges the lifting frame and the adjusting member, so that after the lifting mechanism drives the lifting frame to move, the adjusting member can drive the electric soldering iron to move a certain amount, so that the soldering iron tip on the electric soldering iron can continuously abut against the part to be welded on the automobile connector, and the adjusting member can provide stable pressure to ensure the abutment force of the soldering iron tip on the electric soldering iron, thereby effectively ensuring the abutment effect of the soldering iron tip and the part to be welded on the automobile connector, thereby ensuring the welding effect.

[0010] Preferably, the smoke extraction mechanism further comprises a plurality of additional tubes, one end of each of the additional tubes is connected to the air inlet end of the smoke extractor, and the other end thereof extends downward and toward the automobile connector on the machine body.

[0011] By adopting the above-mentioned technical solution, the additional pipe is set up so that the additional pipe can be close to the automobile connector to be welded or being welded on the machine body, so that the harmful smoke generated during welding can immediately enter the additional pipe and be extracted by the smoke extractor through the additional pipe, effectively reducing the diffusion of the smoke generated during welding and further improving the safety of the welding system of the present application.

[0013] By adopting the above technical solution, the avoidance mechanism is set up so that when the moving mechanism drives the moving frame to move, thereby causing the soldering iron to move, the avoidance component can drive the corresponding avoidance frame to rotate, so that the avoidance frame gives way to the soldering iron, effectively reducing the probability of collision between the additional pipe and the soldering iron, and at the same time effectively allowing the end of the avoidance hose to be as close to the welding point as possible, further improving the safety of the welding system of the present application.

[0014] Preferably, the avoidance assembly includes a drive frame and a transmission frame, the drive frame is slidingly connected to the body, one end of the transmission frame is rotationally connected to the corresponding drive frame, and the other end is slidingly connected to the corresponding avoidance frame, and a drive member is also provided on the body, and the drive member is used to drive the corresponding drive frame to slide.

[0015] By adopting the above technical solution, the avoidance component is set up so that the driving member can drive the driving frame to slide, thereby causing the driving frame to drive the corresponding transmission frame to displace, and then causing the transmission frame to drive the corresponding avoidance frame to rotate, thereby realizing the driving of the avoidance frame, so that the driving member does not need to be set on the additional pipe, which effectively facilitates the installation of the driving member.

[0016] Preferably, a rotating frame and a rotating assembly are further provided on the avoidance frame. The top of the rotating frame is rotatably connected to the corresponding avoidance frame. The end of the avoidance hose away from the smoke extractor is connected to the rotating frame. The rotating assembly is used to drive the rotating frame to rotate when the avoidance frame rotates.

[0017] By adopting the above technical solution, the arrangement of the rotating frame and the rotating assembly enables the rotating assembly to drive the rotating frame to rotate when the avoidance frame rotates, so that when the avoidance frame rotates, the rotating frame can rotate synchronously, and the end of the avoidance hose on the rotating frame can continue to face the vehicle connector on the body.

[0018] Preferably, the rotating assembly includes a linkage, a sliding frame and a driven frame, the sliding frame is slidingly connected to the corresponding avoidance frame, one end of the driven frame is rotationally connected to the corresponding sliding frame, and the other end is rotationally connected to the bottom of the corresponding rotating frame, and the driving frame drives the corresponding sliding frame to slide through the linkage.

[0019] By adopting the above technical solution and arranging the rotating assembly, when the driving frame slides, the driving frame can drive the corresponding sliding frame to slide through the linkage member, so that the sliding frame drives the driven frame to move, and then the rotating frame rotates, thereby driving the rotating frame to rotate.

[0022] Preferably, the driving member includes an abutment frame, which is arranged on the movable frame. Each of the driving frames is located on the displacement path of the abutment frame when the movable frame moves. Each of the driving frames is provided with a guide surface at one end close to the abutment frame. The abutment frame drives the corresponding driving frame to slide by abutting against the guide surface on the driving frame.

[0023] By adopting the above technical solution, the abutment frame is set so that when the abutment frame moves with the mobile frame, the abutment frame can gradually abut against the guide surface on the corresponding drive frame, thereby pushing the corresponding drive frame to slide, thereby realizing the driving of the drive frame to slide, and then effectively realizing the linkage between the mobile frame and the multiple drive frames, effectively facilitating the operation of relevant personnel, and at the same time reducing the active devices that drive the multiple drive frames to slide.

The arrangement of the lifting frame and the adjusting member ensures that after the lifting mechanism drives the lifting frame to move, the adjusting member can drive the electric soldering iron to move a certain distance, so that the soldering iron tip on the electric soldering iron can continuously contact the part to be welded on the automotive connector.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] Example 1: Example 1 of the present application discloses an automatic continuous multi-point welding system. Figure 1 and Figure 2 The automatic continuous multi-point welding system includes a body 1, a mobile frame 2, and a moving mechanism 3. The mobile frame 2 is also equipped with a lifting mechanism 4 and a soldering iron 5. The mobile frame 2 is also equipped with a lifting frame 6. The lifting mechanism 4 is used to drive the lifting frame 6 to move up and down. The lifting frame 6 is also equipped with an adjustment member 7. The adjustment member 7 is used to drive the soldering iron 5 to move in the same direction as the lifting direction of the lifting frame 6, so that the soldering iron tip of the soldering iron 5 contacts the part to be soldered on the vehicle connector.

[0035] Reference Figure 1 The machine body 1 is provided with a processing table 11. A jig 12 is fixedly mounted on the top of the processing table 11. The top of the jig 12 is provided with a plurality of grooves, which are evenly spaced along the moving direction of the movable frame 2. An automotive connector to be processed is placed in each groove to limit and position the automotive connector, facilitating soldering with the soldering iron 5. In other embodiments, the number of jigs 12 on the processing table 11 can be set to two or more.

[0036] Reference Figure 1 The movable frame 2 is slidably connected to the machine body 1 via a slide rail, and the sliding direction is the longitudinal direction of the machine body 1. In the embodiment of the present application, the movable mechanism 3 is configured as a combination of a servo motor and a screw rod. The servo motor is fixedly mounted on the side wall of the top end of the machine body 1, and the output shaft is fixedly connected to one end of the screw rod via a coupling. Both ends of the screw rod are rotatably connected to the machine body 1 via bearings, and one end of the screw rod passes through the movable frame 2 and is threadedly connected to the movable frame 2 to achieve driving of the movable frame 2.

[0037] Reference Figure 1 and Figure 2 In the embodiment of the present application, the lifting mechanism 4 is configured as a cylinder, which is fixedly installed in the mobile frame 2, and the piston rod is vertically arranged and extends downwardly out of the mobile frame 2. The bottom end of the piston rod of the cylinder is fixedly connected to the lifting frame 6 to realize the lifting of the lifting frame 6.

[0038] Reference Figure 2 In the embodiment of the present application, the adjusting member 7 is configured as a cylinder, which is fixedly mounted on the bottom of the lifting frame 6, and the piston rod is arranged vertically downward and is fixedly connected to the soldering iron 5 through the frame body, and the above-mentioned frame body is slidably connected to the lifting frame 6, and the sliding direction is the vertical direction (that is, the lifting direction of the lifting frame 6).

[0039] Reference Figure 2 The air cylinder is sealed and filled with a high-pressure gas such as nitrogen. This allows the air cylinder to exert an elastic force on the soldering iron 5, acting as a gas spring. This allows the soldering iron 5 to slide relative to the lifting frame 6. This elastic force allows the tip of the soldering iron 5 to continuously contact the automotive connector to be soldered, ensuring a strong and effective contact. The use of an air cylinder as a gas spring is well known in the art and will not be further described here.

[0040] Reference Figure 1 and Figure 2 A spot soldering mechanism 8 is also provided on the lifting frame 6. The spot soldering mechanism 8 includes a conveying component 81 and a spot welding head 82. In the embodiment of the present application, the conveying component 81 is configured as a combination structure of a storage box, a conveying pump and a conveying pipe. The storage box is fixedly installed in the mobile frame 2 and stores solder inside.

[0041] Reference Figure 1 and Figure 2 The delivery pipe is a flexible tube, one end of which is connected to the storage tank and the other end to the spot welding head 82. A delivery pump is mounted on the delivery pipe to extract and deliver the solder. The spot welding head 82 is bolted to the lifting frame 6, with the discharge end directed toward the soldering point at the bottom of the soldering iron 5.

[0042] Reference Figure 1 The body 1 is also provided with a smoke extraction mechanism 9, which includes a smoke extractor 91. The smoke extractor 91 is pivotally connected to the top of the body 1 via a pin, and the air intake of the smoke extractor 91 is directed toward the welding point of the soldering iron tip at the bottom of the electric soldering iron 5 to extract the fumes generated during welding. In this embodiment of the present application, the smoke extractor 91 is also provided with fixing bolts, so that personnel can tighten the bolts to secure the smoke extractor 91 to the frame on the body 1, so that the smoke extractor 91 maintains its current orientation.

[0043] The operating principle of an automatic continuous multi-point welding system according to Example 1 of the present application is as follows: When welding an automotive connector, the movable mechanism 3 drives the movable frame 2 to move above the corresponding automotive connector. Then, the lifting mechanism 4 drives the lifting frame 6 downward, so that the tip of the soldering iron 5 below the lifting frame 6 approaches the area to be welded on the automotive connector. Thereafter, the adjusting member 7 (i.e., the cylinder serving as the gas spring) applies a downward elastic force to the soldering iron 5, causing it to move downward a certain distance, thereby ensuring that the tip of the soldering iron continuously contacts the area to be welded on the automotive connector, ensuring both the strength and effectiveness of the contact.

[0044] After that, the spot welding head 82 applies solder to the area to be welded, and the electric soldering iron 5 welds the area where the solder has been applied. After welding is completed, the lifting mechanism 4 drives the lifting frame 6 to move upward, and the moving mechanism 3 drives the moving frame 2 to move to the top of the next car connector, and the welding is repeated continuously.

[0045] Example 2: The difference between Example 2 of the present application and Example 1 is that: Figure 3 and Figure 4 The smoke extractor 91 is fixedly mounted on the housing 1 via a frame. The smoke extraction mechanism 9 further includes a connecting cover 92 and a plurality of additional pipes 93. The connecting cover 92 is sleeved on the housing of the smoke extractor 91. The additional pipes 93 are located on the side of the connecting cover 92 away from the smoke extractor 91 and are distributed along the length of the connecting cover 92.

[0046] Reference Figure 3 One end of each additional tube 93 is connected to the interior of the connecting cover 92 and is fixedly connected to the connecting cover 92, and the other end extends downward. In other embodiments, each additional tube 93 is directed toward the automotive connector to be welded on the processing table 11 of the machine body 1 and is close to the part to be welded.

[0047] Reference Figure 3 and Figure 4 Each expansion tube 93 has a bypass mechanism 10 installed on its downwardly extending end. Each bypass mechanism 10 comprises a bypass hose 101, a bypass frame 102, and a bypass assembly 103. An annular frame is fixedly mounted on the outer side of the bottom end of each expansion tube 93. Each bypass frame 102 is pivotally connected to the corresponding annular frame at the bottom of the expansion tube 93 via a pin. Each bypass assembly 103 comprises a drive frame 1031 and a transmission frame 1032. The drive frame 1031 is slidably connected to the machine body 1 via a slide rail, and the sliding direction is the width direction of the machine body 1.

[0048] Reference Figure 3 and Figure 4Each drive frame 1031 has an arc-shaped guide surface on its end close to the mobile frame 2. Each drive frame 1031 has a return spring 104 on its end away from the mobile frame 2. One end of each return spring 104 abuts against the side wall of the drive frame 1031 and the other end abuts against the body 1, thereby restoring the drive frame 1031 through its own elastic force.

[0049] Reference Figure 3 and Figure 4 In the embodiment of the present application, each avoidance assembly 103 includes two transmission frames 1032, located on opposite sides of the corresponding drive frame 1031. One end of each transmission frame 1032 is pivotally connected to the corresponding drive frame 1031 via a pin, and the other end extends downward, passes through the corresponding avoidance frame 102, and is slidably connected to the corresponding avoidance frame 102, sliding along its own length.

[0050] Reference Figure 3 and Figure 4 The movable frame 2 is also provided with a driving member 21, which includes an abutting frame 211. The abutting frame 211 is fixedly connected to the bottom end of the movable frame 2, and the bottom of the abutting frame 211 is bent and extended in the direction close to the driving frame 1031 to form an abutting portion 2111. Each driving frame 1031 is located on the displacement path of the abutting portion 2111, so that the abutting frame 211 can abut against the guide surface on the corresponding driving frame 1031 during the movement of the movable frame 2, thereby pushing the driving frame 1031 to slide and realize driving the driving frame 1031. In other embodiments, the driving member 21 can also be configured as a plurality of active devices such as electric push rods and cylinders corresponding to the driving frames 1031 to realize active control of the driving frames 1031.

[0051] Reference Figure 3 and Figure 4 In the initial state, the driving frame 1031 is located at the end of its sliding path close to the moving frame 2 under the elastic force of the return spring 104. At this time, the avoidance frame 102 is away from the end of the corresponding additional tube 93 and close to the welding point. As the abutting frame 211 slides with the moving frame 2 and gradually approaches the corresponding driving frame 1031, when the abutting portion 2111 contacts the guide surface of the corresponding driving frame 1031, the abutting portion 2111 pushes the corresponding driving frame 1031 to slide.

[0052] Reference Figure 3 and Figure 4During this process, the drive frame 1031 causes the corresponding transmission frame 1032, to which the drive frame 1031 is rotatably connected, to displace, thereby changing the tilt direction of the transmission frame 1032. This in turn causes the transmission frame 1032 to rotate the corresponding avoidance frame 102, causing the avoidance frame 102 to move away from the end corresponding to the additional tube 93 and away from the electric soldering iron 5 and the spot welding head 82. During this process, the transmission frame 1032 slips relative to the avoidance frame 102.

[0053] Reference Figure 4 and Figure 5 Each avoidance frame 102 is equipped with a rotating frame 105 and a rotating assembly 106. The top of each rotating frame 105 is rotatably connected to the end of the corresponding avoidance frame 102 away from the corresponding expansion tube 93 via a pin. One end of each avoidance hose 101 is fixedly sleeved on the bottom of the corresponding expansion tube 93, and the other end is fixedly sleeved on the corresponding rotating frame 105 or fixedly connected to the inner wall of the annular opening of the corresponding rotating frame 105.

[0054] Reference Figure 4 and Figure 5 Each avoidance frame 102 is provided with two rotating assemblies 106, and is located on opposite sides of the corresponding avoidance frame 102. Each rotating assembly 106 includes a linkage member 1061, a sliding frame 1062, and a driven frame 1063. Each linkage member 1061 includes a linkage frame 10611. One end of each linkage frame 10611 is rotatably connected to the middle part of the corresponding transmission frame 1032 via a pin, and the other end is rotatably connected to the corresponding sliding frame 1062 via a pin.

[0055] Reference Figure 4 and Figure 5 Each sliding frame 1062 is sleeved on the corresponding avoidance frame 102 and is slidably connected to the corresponding avoidance frame 102, and the sliding direction is the extension direction of the avoidance frame 102. One end of each driven frame 1063 is rotatably connected to the corresponding sliding frame 1062 via a pin, and the other end is rotatably connected to the bottom of the corresponding rotating frame 105 via a pin.

[0056] Reference Figure 3 、 Figure 4 and Figure 5 In the initial state, that is, when the contact frame 211 does not abut against the driving frame 1031 and thus does not cause the avoidance frame 102 to rotate, the sliding frame 1062 is located at the end of its sliding path close to the rotating frame 105. When the contact frame 211 abuts against the driving frame 1031, causing the driving frame 1031 to drive the transmission frame 1032 to slide obliquely upward relative to the avoidance frame 102, the transmission frame 1032 drives the corresponding linkage frame 10611 to move, thereby causing the linkage frame 10611 to drive the corresponding sliding frame 1062 away from the rotating frame 105.

[0057] Reference Figure 3 、 Figure 4 and Figure 5 During this process, the sliding frame 1062 drives the corresponding rotating frame 105 to rotate through the corresponding driven frame 1063, and makes the end of the avoidance hose 101 on the rotating frame 105 gradually face downward, so that it continues to face the welding area below, and then continues to extract the smoke generated during welding.

[0058] The implementation principle of the automatic continuous multi-point welding system of Example 2 of the present application is as follows: when the movable frame 2 is displaced under the drive of the moving mechanism 3, the movable frame 2 gradually approaches the corresponding driving frame 1031. When the abutting portion 2111 abuts against the guide surface on the corresponding driving frame 1031, the abutting portion 2111 pushes the corresponding driving frame 1031 to slide. During this process, the driving frame 1031 drives the corresponding transmission frame 1032 and the end thereof connected to the same for rotation to displace together, thereby changing the tilt direction of the transmission frame 1032, and then causing the transmission frame 1032 to drive the corresponding avoidance frame 102 to rotate, so that the avoidance frame 102 is away from the end of the corresponding additional tube 93 and away from the electric soldering iron 5 and the spot welding head 82.

[0059] During this process, the transmission frame 1032 slides relative to the avoidance frame 102, causing the transmission frame 1032 to drive the corresponding linkage frame 10611 to move, and then the linkage frame 10611 drives the corresponding sliding frame 1062 away from the rotating frame 105. At this time, the sliding frame 1062 drives the corresponding rotating frame 105 to rotate through the corresponding driven frame 1063, causing the end of the avoidance hose 101 on the rotating frame 105 to gradually point downward, continuing to face the welding area below, and thus continuing to extract the fumes generated during welding.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
