Description

Technical Field

[0001] The invention belongs to the technical field of soldering, in particular to a DC head soldering device. Background Art

[0002] The DC line and the copper head are usually connected by soldering. The traditional soldering method is: the worker first removes the insulating rubber on the DC line head, then holds the DC line in one hand and the copper head in the other hand to connect the DC line and the copper head, and moves the DC line and the copper head to the soldering iron of the soldering machine. The tip of the soldering iron melts the tin wire and solders the DC line and the copper head together. This soldering method is inefficient, and because the size of the copper head is very small, when the worker is operating, his hands are very close to the soldering iron, which is easy to get burned and has poor safety.

[0006] The copper head feeding mechanism includes a second slider, the second slider is connected to a second driving mechanism that drives the second slider to move toward the soldering mechanism; a horizontal butt joint and a vertical positioning plate are provided on the second slider, one end of the butt joint is fixedly connected to the positioning plate, a plurality of axially extending notches are provided on the butt joint facing the positioning plate, the length of the notch is less than the length of the butt joint, a plurality of radially extending slide grooves are provided on the positioning plate, one end of each notch is connected to the outer end of the slide groove, a clamping claw is provided in each notch, the clamping claw passes through the slide groove and is connected to a clamping driving mechanism that drives the clamping claw to move radially; a hopper is provided above the second slider, the hopper is installed on the first lifting mechanism, and an arc-shaped conveying pipe is fixedly provided at the bottom of the hopper, the tangent of the outer wall of the lower end of the conveying pipe is horizontal, and the lower port of the conveying pipe can be connected to the butt joint;

[0008] Furthermore, the wire locking mechanism includes a feed roller, a support block and a wire end detection element which are arranged in sequence, the upper surface of the support block is provided with a lower positioning groove with a semicircular cross-section, a pressure roller is provided above the lower positioning groove, and the surface of the pressure roller is provided with an annular upper positioning groove, the upper positioning groove and the lower positioning groove form a positioning cavity, and both ends of the pressure roller are installed on the third slider through bearings, and the third slider is connected to a third driving mechanism for driving the third slider to move linearly.

[0009] Furthermore, a vertical turntable is arranged below the soldering mechanism, the turntable is connected to a rotating drive mechanism for driving the turntable to rotate, there are multiple supporting grooves which are evenly distributed on the circumferential surface of the turntable, and the supporting grooves penetrate the turntable along the axial direction of the turntable; a residual tin cleaning mechanism is arranged below the turntable.

The positioning plate plays a role in positioning the copper head, ensuring that each copper head has the same length outside the butt joint pipe after reaching the butt joint pipe.

At the same time, the worker feeds the wire into the wire locking mechanism, the wire locking mechanism locks the wire, and then uses the first slider to drive the wire to move to the bottom of the soldering mechanism. At this time, the end of the wire contacts the end of the copper head, and the end of the wire and the end of the copper head are both supported by the support groove. The second lifting mechanism drives the soldering mechanism to move downward to weld the end of the wire to the end of the copper head.

[0016] The present invention can realize semi-automatic operation. Workers only need to put the copper head into the hopper and put the wire into the wire locking mechanism. Both hands do not need to be close to the soldering iron, thereby avoiding burns, improving the safety of operation, and reducing labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] The DC head soldering device of the present invention is as follows Figures 1 to 5 As shown, the workbench 100 includes a wire feeding mechanism, a soldering mechanism and a copper head feeding mechanism which are sequentially arranged on the workbench 100. The workbench 100 is arranged horizontally, and a set of supporting legs are arranged at the bottom so that the workbench 100 is at a suitable height. The workbench 100 can be made of a metal plate of a certain thickness.

[0025] The wire feeding mechanism is used to convey the wire to the bottom of the soldering mechanism. Specifically, the wire feeding mechanism includes a first slider 1, which is slidably matched with the workbench 100. The first slider 1 is connected to a first driving mechanism 2 that drives the first slider 1 to move toward the soldering mechanism. The first slider 1 is provided with a wire locking mechanism, which is used to lock the wire so that the wire remains stable so as to facilitate stable docking with the copper head.

[0026] The copper head feeding mechanism is used to transport the copper head to the bottom of the soldering mechanism. Specifically, the copper head feeding mechanism includes a second slider 3, the second slider 3 is slidably matched with the workbench 100, and the second slider 3 is connected to a second driving mechanism 4 that drives the second slider 3 to move toward the soldering mechanism. The first driving mechanism 2 and the second driving mechanism 4 can adopt common reciprocating linear driving devices such as cylinders, hydraulic cylinders, and linear motors.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, a horizontal butt joint pipe 5 and a vertical positioning plate 6 are provided on the second slider 3. The butt joint pipe 5 is a circular pipe, and its inner diameter is larger than the diameter of the copper head, and its length is smaller than the length of the copper head. Both the butt joint pipe 5 and the positioning plate 6 are fixed on the second slider 3. The axial direction of the butt joint pipe 5 is consistent with the sliding direction of the second slider 3, and one end of the butt joint pipe 5 facing the soldering mechanism extends beyond the edge of the second slider 3. The positioning plate 6 is a circular plate, one end of the butt joint pipe 5 is fixedly connected to the positioning plate 6, and the positioning plate 6 is coaxial with the butt joint pipe 5.

[0028] A plurality of axially extending notches 7 are provided at one end of the butt joint pipe 5 facing the positioning plate 6. The length of the notches 7 is less than the length of the butt joint pipe 5, that is, the notches 7 do not penetrate the butt joint pipe 5 axially. A plurality of radially extending slide grooves 8 are provided on the positioning plate 6. One end of each notch 7 is connected to the outer end of the slide groove 8. The outer end of the slide groove 8 refers to the end of the slide groove 8 away from the center of the positioning plate 6. A clamping jaw 9 is provided in each notch 7. The clamping jaw 9 penetrates the slide groove 8 and is connected to a clamping drive mechanism 10 for driving the clamping jaw 9 to move radially. The clamping drive mechanism 10 can drive each clamping jaw 9 to move radially toward the center of the butt joint pipe 5 to center the copper head. The clamping drive mechanism 10 can adopt existing technology, such as a hydraulic chuck, and can specifically be a commonly used three-jaw chuck, four-jaw chuck, etc.

[0029] A hopper 11 is arranged above the second slider 3. The hopper 11 is truncated cone-shaped, with an inner diameter at the upper end larger than that at the lower end, and the upper end is open, so that workers can quickly and accurately put the copper head into the hopper 11. The hopper 11 is installed on the first lifting mechanism 12. An arc-shaped conveying pipe 13 is fixedly arranged at the bottom of the hopper 11. The upper end of the conveying pipe 13 is connected to the hopper 11. The tangent of the outer wall of the lower end of the conveying pipe 13 is horizontal. The inner diameter of the conveying pipe 13 is the same as that of the butt joint 5, and the lower end of the conveying pipe 13 can be connected to the butt joint 5. When the copper head is fed, the second slider 3 drives the butt joint 5 to be in a suitable position, and the butt joint 5 is connected to the lower end of the conveying pipe 13.

[0030] The soldering mechanism is used to solder the wire end and the copper head end. A support groove 14 is provided below the soldering mechanism, and the soldering mechanism is installed on the second lifting mechanism 15. Since the soldering iron 33 needs to apply a certain pressure to the wire end and the copper head end during welding to ensure the stability of the welding connection, the support groove 14 is used to support the wire end and the copper head end. The soldering mechanism specifically includes a soldering iron 33 and a tinning mechanism 34 provided on both sides of the soldering iron 33. The soldering iron 33 and the tinning mechanism 34 are respectively installed on different second lifting mechanisms 15. A fixed sleeve 35 is provided above the support groove 14. The soldering iron 33 is located inside the sleeve 35, and an insulation layer 36 is provided on the outer wall of the sleeve 34. The tinning mechanism 34 is used to tin the wire end and the copper head end. The soldering iron 33 can be heated to 390±30 degrees Celsius to melt the tin at the wire end and the copper head end. The molten tin connects the wire end and the copper head end into one. The tinning mechanism 34, the soldering iron 33, etc. can all be made of existing technology. In the welding gap, the soldering iron 33 is located inside the sleeve 35, and the soldering iron 33 is insulated by the heat insulation layer 36 to reduce the heat loss of the soldering iron 33, thereby reducing energy consumption. When soldering, the second lifting mechanism 15 is used to drive the soldering iron 33 to move downward to the welding position. The second lifting mechanism 15 can be a hydraulic cylinder or other equipment.

[0031] Since the diameter and length of the copper head are relatively small, a hopper 11 is used as the copper head feeding part. The top of the hopper 11 has a large opening, so that workers can quickly and accurately put the copper head into the hopper 11. After the copper head enters the hopper 11, it enters the conveying pipe 13 under the action of its own gravity, and slides down along the conveying pipe 13 into the docking pipe 5. Since the length of the docking pipe 5 is smaller than the length of the copper head, one end of the copper head stops moving after reaching the positioning plate 6. The positioning plate 6 plays a role in positioning the copper head, ensuring that after each copper head reaches the docking pipe 5 and stops moving, the length of the copper head outside the docking pipe 5 is the same. After the copper head enters the docking pipe 5, the clamping drive mechanism 10 drives the clamping claw 9 to center the copper head, and then the second slide block 3 moves a distance in the direction away from the conveying pipe 13, so that the copper head is completely separated from the conveying pipe 13, and then the first lifting mechanism 12 drives the hopper 11 and the conveying pipe 13 to move upward for a distance as a whole, and the second slide block 3 drives the copper head to move to the bottom of the soldering mechanism. At the same time, the worker feeds the wire into the wire locking mechanism, which locks the wire, and then uses the first slider 1 to drive the wire to move to the bottom of the soldering mechanism. At this time, the end of the wire contacts the end of the copper head, and the end of the wire and the end of the copper head are supported by the support groove 14. The second lifting mechanism 15 drives the soldering mechanism to move downward to weld the end of the wire to the end of the copper head. After welding is completed, the clamping drive mechanism 10 drives the clamping jaws 9 to release the copper head, and the wire can be removed from the wire locking mechanism.

[0032] In the present invention, Figure 1 and Figure 2 As shown, the wire locking mechanism includes a feed roller 16, a support block 17 and a wire end detection element 22 arranged in sequence, and the upper surface of the support block 17 is provided with a lower positioning groove 18 with a semicircular cross section. There are two feed rollers 16, and there is a certain gap between the two feed rollers 16, which is adapted to the outer diameter of the wire. When the worker inserts one end of the wire into the gap between the two feed rollers 16, the feed roller 16 rotates, which can drive the wire to move to the lower positioning groove 18 on the support block 17. When the wire passes through the lower positioning groove 18 and reaches the detection position of the wire end detection element 22, the wire stops moving. The wire end detection element 22 is used to check whether the end of the wire reaches the set position. Specifically, a commonly used item detection element such as a photoelectric sensor can be used. The wire end detection element 22 can be connected to a controller, and the operation of the feed roller 16 is controlled by the controller. When the wire end detection element 22 detects that the end of the wire reaches the set position, it transmits a signal to the controller, and the controller controls the feed roller 16 to stop running. Accurately controlling the position of the wire end can ensure that the wire end is accurately connected with the copper head end, ensure the accuracy of the welding position, and improve the welding quality.

[0033] Since the wire has a certain flexibility and is usually curved, the end of the wire is easy to deviate from the welding position. Therefore, in the present invention, a pressure roller 19 is arranged above the lower positioning groove 18, and a ring-shaped upper positioning groove 20 is arranged on the surface of the pressure roller 19. The upper positioning groove 20 and the lower positioning groove 18 form a positioning cavity, which is a circular cavity, and its inner diameter is adapted to the outer diameter of the wire. The two ends of the pressure roller 19 are installed on the third slider 21 through bearings. The third slider 21 is slidably matched with the support block 17, and the third slider 21 is connected to a third driving mechanism 23 that drives the third slider 21 to move linearly. The initial position of the pressure roller 19 is the end of the lower positioning groove 18 close to the feed roller 16. When the wire enters the lower positioning groove 18, the third driving mechanism 23 drives the third slider 21 and the pressure roller 19 to move back and forth linearly for many times. The moving direction of the pressure roller 19 is consistent with the length direction of the wire. During the movement of the pressure roller 19, the wire can be straightened to ensure that the end of the wire can accurately reach the welding position. The third driving mechanism 23 can be a cylinder, a hydraulic cylinder and other equipment.

[0034] During the soldering process, the soldering iron 33 heats the tin to a molten state, and the tin easily adheres to the support groove 14. Therefore, after each soldering for a certain number of times, the residual tin on the support groove 14 needs to be cleaned. Manual cleaning can be done, but the cleaning efficiency is low, which affects the normal soldering operation. In order to avoid affecting the soldering operation when cleaning the residual tin in the support groove 14, such as Figure 1As shown, the present invention is provided with a vertical turntable 24 below the soldering mechanism. The turntable 24 is a circular disk. The turntable 24 is connected to a rotation drive mechanism 25 for driving the turntable 24 to rotate. The rotation drive mechanism 25 can be a servo motor or other equipment. There are multiple support grooves 14 that are evenly distributed on the circumference of the turntable 24, and the support grooves 14 penetrate the turntable 24 along the axial direction of the turntable 24; a residual tin cleaning mechanism is provided below the turntable 24. Specifically, there can be two support grooves 14, one of which is located at the top of the turntable 24 to support the wire end and the copper head end, and the other support groove 14 is located at the bottom of the turntable 24, waiting for standby. When it is necessary to clean the support groove 14 on the top of the turntable 24, the rotating driving mechanism 25 drives the turntable 24 to rotate 180°, so that the support groove 14 on the top of the turntable 24 moves to the bottom of the turntable, and the residual tin can be cleaned by the residual tin cleaning mechanism, and the support groove 14 originally located at the bottom of the turntable 24 moves to the top of the turntable 24, which can support the end of the wire and the end of the copper head without affecting the normal soldering operation.

[0035] The residual tin cleaning mechanism can adopt a scraper mechanism, which can scrape off the tin on the inner wall of the support groove 14, but it is not convenient to recover the scraped tin. Figure 1 and Figure 5 As shown, the residual tin cleaning mechanism includes a third lifting mechanism 26, which can be a hydraulic cylinder or other equipment. A support 27 is provided on the top of the third lifting mechanism 26, and a conveying block 28 is provided on the upper surface of the support 27. A conveying trough with a semicircular cross-section is provided on the upper surface of the conveying block 28. The cross-section of the support trough 14 is also semicircular. The inner diameter of the conveying trough is the same as the inner diameter of the support trough 14. The conveying trough can form a circular cavity with the support trough 14. A horizontal rotating shaft 29 is provided in the conveying trough. The rotating shaft 29 is coaxial with the conveying trough. A spiral conveying piece 30 is provided on the rotating shaft 29. One side edge of the spiral conveying piece 30 is fixed on the rotating shaft 29, and the other side edge contacts the inner wall of the conveying trough. A scraper motor 31 is connected to one end of the rotating shaft 29. The scraper motor 31 is used to drive the rotating shaft 29 and the spiral conveying piece 30 to rotate. A collecting box 32 is connected to the end of the conveying trough. The collecting box 32 can be fixed on the support 27 to collect the scraped tin.

[0036] When the support groove 14 needs to be cleaned, the rotating drive mechanism 25 drives the turntable 24 to rotate 180°, so that the support groove 14 to be cleaned reaches the top of the conveying block 28, and then the third lifting mechanism 26 is used to push the conveying block 28 upward, so that the conveying block 28 contacts the turntable 24, and at the same time, the conveying groove and the support groove 14 form a circular cavity, and the edge of the spiral conveying sheet 30 contacts the inner wall of the support groove 14, and then the scraper motor 31 is started, and the scraper motor 31 drives the spiral conveying sheet 30 to rotate, so that the residual tin on the inner wall of the support groove 14 can be scraped off. At the same time, the spiral conveying sheet 30 has a conveying function, which can push the residual tin into the collection box 32 to realize the recovery of the residual tin. After the soldering is completed, the support groove 14 to be cleaned is immediately transferred to the top of the conveying block 28. At this time, the tin still has a higher temperature and is relatively soft, so it can be scraped off by the spiral conveying sheet 30.

[0037] A horizontal guide rail is provided on the workbench 100 , and the first slider 1 and the second slider 3 are both slidably matched with the guide rail. The guide rail has guiding and positioning functions, and can improve the stability of the movement of the first slider 1 and the second slider 3 .

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
