Abstract
Description
Technical Field
[0001] This invention relates to the field of production equipment technology, and in particular to an automatic soldering machine. Background Technology
[0002] Existing coil products, such as transformer coils and contactor coils, typically require soldering of their leads. During soldering, the leads of these coil products need to be immersed in molten solder. At this time, the coil body is close to the surface of the molten solder, making it susceptible to solder splashes, contact contamination, and fumes. To address this issue, some coil products are coated with a protective film before soldering to prevent contamination from the molten solder. While this method effectively isolates the coil from the solder, the process relies on manual labor, including coating before soldering and removing the film afterward. This process is not only cumbersome, but more importantly, the film removal step usually needs to be performed off-line, disrupting the flow of coil products on the production line and severely damaging production continuity, making it difficult to meet the requirements of large-scale, high-efficiency production. Summary of the Invention
[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an automatic soldering machine that can protect the body of coil-type products using a fixture, reducing the possibility of them being contaminated by molten solder. Furthermore, it can mechanically remove and transport coil-type products with soldered leads from the fixture, facilitating connection to subsequent production equipment for processing, ensuring production continuity, and adapting to the requirements of large-scale, high-efficiency production.
[0004] The automatic soldering machine according to an embodiment of the present invention includes a fixture, a frame, and a first conveying mechanism, a transporting mechanism, a fluxing mechanism, a soldering mechanism, and a second conveying mechanism disposed on the frame. The fixture includes a box and a cover. The box has a receiving cavity for placing coil-type products. The cover is detachably disposed on the box and can cover the receiving cavity. The box and / or the cover has clearance notches to allow the leads of the coil-type products to extend from the receiving cavity. The frame is provided with a worktable. The first conveying mechanism can load and convey the fixture containing the coil-type products to the worktable. The fluxing mechanism can hold flux. The soldering mechanism is capable of holding and heating molten solder. The conveying mechanism is capable of acquiring the fixture on the workbench and moving the fixture between the workbench, the fluxing mechanism, and the soldering mechanism, so that the pins can be immersed in flux and molten solder. The conveying mechanism and the first conveying mechanism can cooperate to separate the cover and the box. The conveying mechanism can transport the box separated from the cover to the second conveying mechanism. The second conveying mechanism can remove coil products from the box and convey them for unloading. The first conveying mechanism can convey the separated cover and box for unloading.
[0005] The automatic soldering machine according to the embodiments of the present invention has at least the following beneficial effects: In use, a coil-type product is placed into the receiving cavity of a housing, with its leads extending from the receiving cavity through clearance notches. A cover is placed on the housing to conceal the body of the coil-type product in the receiving cavity. A fixture containing the coil-type product is loaded onto a first conveying mechanism, which then conveys the fixture to a worktable. A transport mechanism picks up the fixture from the worktable and transports it to a fluxing mechanism, immersing the leads extending from the fixture in the flux of the fluxing mechanism for a preset time. Subsequently, the transport mechanism transports the fixture to a soldering mechanism. The process involves immersing the leads in the molten solder of the soldering mechanism for a preset time to perform soldering. After soldering, a transport mechanism moves the fixture to the worktable. The transport mechanism, in conjunction with a first conveying mechanism, separates the fixture's cover and housing, opening the receiving cavity. The separated cover is then conveyed by the first conveying mechanism. The transport mechanism then transports the housing, separated from the cover, to a second conveying mechanism, which removes the coil-like product from the housing and conveys it. Finally, the transport mechanism transports the housing, now containing the coil-like product, to the worktable and conveys it again via the first conveying mechanism. This invention, by using a fixture to hold the coil-like product to be soldered, protects the product body, reducing the possibility of contamination by molten solder during lead soldering. Furthermore, after soldering, the coil-like product can be mechanically removed from the fixture and conveyed, eliminating the need for manual unpacking and unloading. This facilitates integration with subsequent production equipment, ensuring production continuity and adapting to the requirements of large-scale, high-efficiency production.

[0023] Reference Figures 1 to 8An automatic soldering machine includes a fixture 100, a frame 200, and a first conveying mechanism 300, a handling mechanism 400, a soldering assistance mechanism 500, a soldering mechanism 600, and a second conveying mechanism 700 disposed on the frame 200. The fixture 100 includes a box body 110 and a cover 120. The box body 110 has a receiving cavity 101 for placing coil-type products 10. The cover 120 is detachably disposed on the box body 110 and can cover the receiving cavity 101. The box body 110 and / or the cover 120 are provided with clearance notches 102 to allow the leads 11 of the coil-type products 10 to extend from the receiving cavity 101. The frame 200 is provided with a worktable 210. The first conveying mechanism 300 can load and convey the fixture 100 containing the coil-type products 10 to the worktable 210. The soldering mechanism 500 can hold flux, the soldering mechanism 600 can hold molten solder and heat the molten solder, the conveying mechanism 400 can pick up the jig 100 on the workbench 210 and move the jig 100 between the workbench 210, the fluxing mechanism 500 and the soldering mechanism 600 so that the pin 11 can be immersed in flux and molten solder. The conveying mechanism 400 and the first conveying mechanism 300 can cooperate to separate the cover 120 and the box 110. The conveying mechanism 400 can move the box 110 separated from the cover 120 to the second conveying mechanism 700. The second conveying mechanism 700 can take out the coil product 10 from the box 110 and convey it for unloading. The first conveying mechanism 300 can convey the separated cover 120 and box 110 for unloading.
[0024] Understandably, such as Figures 1 to 8As shown, in use, the coil product 10 is inserted into the receiving cavity 101 of the box 110, with its pins 11 protruding from the receiving cavity 101 through the clearance notch 102. The cover 120 is placed on the box 110 to cover the body of the coil product 10 in the receiving cavity 101. The fixture 100 containing the coil product 10 is loaded onto the first conveying mechanism 300, which conveys the fixture 100 to the worktable 210. The transport mechanism 400 picks up the fixture 100 from the worktable 210 and transports it to the fluxing mechanism 500, immersing the pins 11 protruding from the fixture 100 in the flux of the fluxing mechanism 500 for a preset time. Subsequently, the transport mechanism 400 transports the fixture 100 to the soldering mechanism 600, immersing the pins 11 in the soldering mechanism 600. The fixture 100 is immersed in molten solder for a preset time to perform soldering on pin 11. After soldering is completed, the transport mechanism 400 transports the fixture 100 to the worktable 210. The transport mechanism 400 works in conjunction with the first transport mechanism 300 to separate the cover 120 and the box 110 of the fixture 100, opening the receiving cavity 101. The separated cover 120 is transported and unloaded by the first transport mechanism 300. The transport mechanism 400 transports and unloads the box 110 after it is separated from the cover 120 to the second transport mechanism 700. The second transport mechanism 700 takes out the coil product 10 from the box 110 and unloads it. Then the transport mechanism 400 transports and unloads the box 110 after taking out the coil product 10 to the worktable 210 and unloads it through the first transport mechanism 300. This invention, by setting up a fixture 100 and placing the coil product 10 to be soldered inside it, can protect the body of the coil product 10, reduce the possibility of it being contaminated by molten solder when the pins 11 are soldered, and after soldering, the coil product 10 can be mechanically removed from the fixture 100 and transported for unloading, eliminating the need for manual unpacking and unloading operations. This facilitates connection with subsequent production equipment for processing, ensures production continuity, and is conducive to adapting to the requirements of large-scale and high-efficiency production.
[0025] In practical applications, the coil product 10 can be placed into the receiving cavity 101 of the box 110 and the cover 120 can be closed manually, or a mechanical device can be used to grab the coil product 10 and place it into the receiving cavity 101 of the box 110, and then the cover 120 can be placed on the box 110. The mechanical device can be a multi-axis robot, and the specific settings can be made according to the actual needs of use.
[0026] In some embodiments, the first conveying mechanism 300 includes a first conveyor belt 310, a second conveyor belt 320, a first pusher 330, a first driver 340, a second pusher 350, and a second driver 360. A first positioning part 211 is provided on the worktable 210, and a limiting block 111 capable of abutting or engaging with the coil-type product 10 is provided in the receiving cavity 101. The first conveyor belt 310 is used to convey and load the fixture 100 containing the coil-type product 10. The first driver 340 is drivenly connected to the first pusher 330 and can drive the first pusher 330 to move, thereby moving the coil-type product 10 on the first conveyor belt 310. The fixture 100 is pushed to the workbench 210 and abuts against the first positioning part 211. The box body 110 has a clamping part 115. The conveying mechanism 400 can clamp the clamping part 115 and drive the fixture 100 to flip. The first pusher 330 can cooperate with the first positioning part 211 to clamp the cover 120. The second driver 360 is driven to connect with the second pusher 350 and can drive the second pusher 350 to move so as to push the cover 120 and the box body 110 on the workbench 210 to the second conveyor belt 320. The second conveyor belt 320 is used to transport the cover 120 and the box body 110 for unloading.
[0027] Understandably, such as Figure 1 , Figure 2 and Figure 3As shown, the first conveyor belt 310 and the second conveyor belt 320 are both arranged parallel to the left and right directions. The workbench 210 is connected to the rear right end of the first conveyor belt 310 and the right end of the second conveyor belt 320. The first driver 340 is driven to the first pusher 330 to drive it to move back and forth. The second driver 360 is driven to the second pusher 350 to drive it to move left and right. The first positioning part 211 is located on the rear side of the workbench 210. The left and right sides of the box 110 are provided with clamping parts 115. The front and rear sides of the box 110 are provided with clearance notches 102. The accommodating cavity 101 is provided with a limiting block 111.In use, the coil product 10 is inserted into the receiving cavity 101 of the box 110, with its pins 11 extending from the clearance notch 102. The limiting block 111 is inserted into the coil of the coil product 10 and abuts against its inner side wall. Then, the cover 120 is placed on the box 110 to cover the receiving cavity 101 and the body of the coil product 10 inside. The fixture 100 containing the coil product 10 is placed on the first conveyor belt 310. The first conveyor belt 310 transports the fixture 100 to the right. After it is transported to the correct position, the first driver 340 drives the first pusher 330 to move backward to push the fixture 100 on the first conveyor belt 310 onto the worktable 210 and make the fixture 100... The first positioning part 211 abuts against the 00, achieving front and rear positioning; then the conveying mechanism 400 operates, using the clamping part 115 of the clamping box 110 to obtain the fixture 100, thereby conveying the transfer fixture 100. By driving the fixture 100 to flip, the pins 11 face downwards, facilitating subsequent immersion in flux and solder; after soldering is completed, the conveying mechanism 400 transports the fixture 100 to the worktable 210 and drives the fixture 100 to flip, placing the fixture 100 on the worktable 210 with the cover 120 facing downwards. At this time, the first driver 340 drives the first pusher 330 to move, causing the first pusher 330 to cooperate with the first positioning part 211 to clamp the cover. 120. The conveying mechanism 400 lifts the box 110 upwards, thereby separating the cover 120 from the box 110. The cover 120 remains on the worktable 210. The first driver 340 drives the first pusher 330 forward to release the clamping of the cover 120. The second driver 360 drives the second pusher 350 to move to the left, pushing the cover 120 on the worktable 210 to the second conveyor belt 320. The second conveyor belt 320 transports the cover 120 out of the box. Since the limiting block 111 abuts against and fixes the body of the coil product 10 in an internal support manner, during the separation of the box 110 and the cover 120, the coil product 10 in the receiving cavity 101... It will not fall out and will remain well within the receiving cavity 101. After the box body 110 separates from the cover 120, the conveying mechanism 400 can drive the box body 110 to flip so that the opening faces upward or to the side. The conveying mechanism 400 transports the box body 110 to the second conveying mechanism 700, where the second conveying mechanism 700 removes the coil-type product 10 from the box body 110 and conveys it for unloading. Subsequently, the conveying mechanism 400 transports the box body 110 to the worktable 210. The second driver 360 drives the second pusher 350 to move to the left, pushing the box body 110 on the worktable 210 to the second conveyor belt 320, which then conveys the box body 110 for unloading. The above structure is simple, reasonable, and easy to use.
[0028] In practical applications, in addition to the above structure, the first conveying mechanism 300 can also use a multi-axis robot to grip the fixture 100 to transfer the fixture 100 from the first conveyor belt 310 to the worktable 210 or to transfer the cover 120 and the box 110 on the worktable 210 to the second conveyor belt 320. Alternatively, the multi-axis robot can cooperate with the handling mechanism 400, with one of them gripping the cover 120 and the other gripping the box 110 to separate the cover 120 and the box 110. The specific settings can be configured according to actual usage requirements.
[0029] In some embodiments, the workbench 210 is further provided with a second positioning part 212, which is arranged at a preset angle with the first positioning part 211. The workbench 210 and / or the first positioning part 211 are provided with a first magnetic element 213, and the box 110 is provided with a second magnetic element 112. The first magnetic element 213 and the second magnetic element 112 can be magnetically attracted and misaligned, so that the box 110 has a tendency to move and abut against the second positioning part 212.
[0030] Understandably, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the second positioning part 212 is located on the right side of the workbench 210 and extends towards the first conveyor belt 310, preventing the fixture 100 at the right end of the first conveyor belt 310 from continuing to be conveyed to the right. The first magnetic element 213 is located on the front side of the first positioning part 211, and the second magnetic element 112 is located on the rear side of the box 110. When the fixture 100 is pushed to abut against the first positioning part 211, the magnetic attraction between the first magnetic element 213 and the second magnetic element 112 keeps the box 110 in contact with the first positioning part 211. At the same time, the first magnetic element 213 and the second magnetic element 112 are misaligned, such as... Figure 5 As shown, due to the misalignment of the two magnetic components, the magnetic attraction between them will generate a pulling force to the right or to the lower right, which will cause the box 110 to tend to move to the right. Under this tendency, the box 110 can be kept in contact with the second positioning part 212, achieving a better front-to-back and left-to-right bidirectional positioning effect.
[0031] In practical applications, the first magnetic component 213 can also be disposed on the worktable 210. When the first magnetic component 213 and the second magnetic component 112 are magnetically attracted together, the misalignment requires the generation of a traction force to the right and rear, so that the box 110 has a tendency to move to the right and rear, so as to abut against the first positioning part 211 and the second positioning part 212 respectively. The first positioning part 211 and the second positioning part 212 can be an integral structure, or two independent components relative to the worktable 210. The specific configuration can be set according to the actual use needs.
[0032] In some embodiments, the conveying mechanism 400 includes a first drive module 410, a first motion seat 420, a third driver 430, and a first clamping assembly 440. The first drive module 410 is driven to the first motion seat 420 and can drive the first motion seat 420 to move laterally and longitudinally. The third driver 430 is disposed on the first motion seat 420 and driven to the first clamping assembly 440 and can drive the first clamping assembly 440 to rotate. The first clamping assembly 440 is used to clamp the gripping part 115.
[0033] Understandably, such as Figure 1 and Figure 6 As shown, the first drive module 410 consists of three drive units, namely a forward and backward movement unit, a left and right movement unit, and a up and down movement unit. The drive units can use linear motors, cylinders, or motors and lead screws to achieve the corresponding motion drive. The first drive module 410 is driven to the first motion seat 420 to drive the first motion seat 420 to move in the forward, left and right and up and down directions. The third driver 430 is disposed on the first motion seat 420 and driven to the first clamping assembly 440 to drive it to rotate. The left and right sides of the box 110 are provided with clamping parts 115. Correspondingly, the first clamping assembly 440 is provided with two clamping parts 115 and is distributed at intervals in the left and right directions to clamp the clamping parts 115 on the left and right sides respectively. In use, the transport mechanism 400 clamps the gripping part 115 through the first clamping component 440 to obtain the fixture 100. The third driver 430 drives the first clamping component 440 to rotate, so that the fixture 100 is flipped so that the pin 11 faces down or the cover 120 faces down, etc. The first drive module 410 drives the first motion seat 420 to move in multiple axes to realize the transport and turnover of the fixture 100. When the pin 11 is immersed in the molten solder, the first drive module 410 can also make the pin 11 move in a curve or circle in the molten solder to ensure that the molten solder effectively covers the pin 11.
[0034] In practical applications, in addition to the above structure, the handling mechanism 400 can also move and rotate the first clamping component 440 through a multi-axis manipulator. Its specific structure can be set according to actual usage needs.
[0035] Furthermore, such as Figure 6 As shown, a sixth driver 421 is provided on the first motion seat 420. The sixth driver 421 is connected to a liquid level detector 422 and can drive the liquid level detector 422 to move up and down. The liquid level detector 422 is used to detect the liquid level of the soldering mechanism 600, so that the amount of solder used for each soldering and the amount of solder remaining can be determined according to the liquid level, which is convenient for use.
[0036] In some embodiments, the box body 110 is provided with a third magnetic element 113 and a third positioning part 114, and the cover body 120 is provided with a fourth magnetic element. When the cover body 120 is placed on the box body 110, the third magnetic element 113 and the fourth magnetic element are magnetically attracted and misaligned, so that the cover body 120 has a tendency to move and abut against the third positioning part 114.
[0037] Understandably, such as Figure 3 and Figure 4 As shown, the upper side of the box body 110 is provided with a third positioning part 114. Multiple third positioning parts 114 can be provided and distributed on the left and rear sides of the box body 110, or they can be in an "L" shape, so that both the left and rear sides of the box body 110 have third positioning parts 114. The upper side of the box body 110 is provided with a third magnetic element 113, and the cover 120 is correspondingly provided with a fourth magnetic element (not shown in the figure). When the cover 120 is placed on the box body 110, the third magnetic element 113 and the fourth magnetic element magnetically engage, thereby allowing the cover 120 to remain relatively stable. The cover 120 remains on the box 110 to prevent it from detaching from the box 110 when the fixture 100 is flipped. At the same time, referring to the cooperation between the first magnetic component 213 and the second magnetic component 112, the third magnetic component 113 and the fourth magnetic component are also misaligned when they are magnetically attracted. Through the misalignment of the two magnetic components, a traction force is generated to the left and rear when they are magnetically attracted, so that the cover 120 has a tendency to move to the left and rear. Under this tendency, the cover 120 can be kept in contact with the third positioning part 114, achieving a better front-to-back and left-to-right bidirectional positioning effect.
[0038] In practical applications, the third positioning part 114 can also be distributed on the right side or front side of the box body 110. In addition to magnetic attraction, the cover 120 and the box body 110 can also be fixed by a snap-fit structure. The specific configuration can be changed according to the actual needs of use.
[0039] In some embodiments, the fluxing mechanism 500 includes a main container 510, a first flux cup 520, and a fourth actuator 530. The main container 510 is used to hold flux, and the fourth actuator 530 is driven to connect with the first flux cup 520, enabling the first flux cup 520 to move up and down, so that the first flux cup 520 can be immersed in the flux of the main container 510 or raised to a preset height relative to the main container 510.
[0040] Understandably, such as Figure 1 and Figure 7As shown, the main container 510 has an open structure and is used to hold flux. The fourth actuator 530 is driven by the first cup 520 to move the first cup 520 up and down. In use, the fourth actuator 530 drives the first cup 520 down into the flux immersed in the main container 510, so that the flux fills the first cup 520. When the lead 11 needs to be immersed in flux, the fourth actuator 530 drives the first cup 520 up to a preset height, and then the conveying mechanism 400 immerses the lead 11 into the flux in the first cup 520. This design ensures that the lead 11 is immersed in flux at a consistent height each time, which helps to ensure the quality of soldering.
[0041] In practical applications, in addition to the above structure, the fluxing mechanism 500 can also adopt an inner and outer double-groove structure design, with the inner groove located in the outer groove. Both the inner and outer grooves are filled with flux, and the flux in the outer groove is pumped to the inner groove through the pumping component, so that the inner groove is filled with flux. Excess flux flows back to the outer groove, and the pin 11 is immersed in the flux in the inner groove so that the height of the pin 11 immersed in the flux is consistent each time. The specific settings can be adjusted according to the actual use requirements.
[0042] In some embodiments, the soldering mechanism 600 includes a solder furnace 610, a second molten solder cup 620, a fifth driver 630, a scraper 640, and a second drive module 650. The solder furnace 610 is used to hold molten solder and can heat the molten solder. The second drive module 650 is drivenly connected to the scraper 640 and can drive the scraper 640 to move laterally and longitudinally so that the scraper 640 can scrape off the oxide layer on the surface of the molten solder in the solder furnace 610. The fifth driver 630 is drivenly connected to the second molten solder cup 620 and can drive the second molten solder cup 620 to move up and down so that the second molten solder cup 620 can be immersed in the molten solder in the solder furnace 610 or raised to a preset height relative to the solder furnace 610.
[0043] Understandably, such as Figure 1 and Figure 7As shown, the second drive module 650 consists of two drive units: a forward and backward movement unit and a vertical movement unit. The drive units can be driven by linear motors, cylinders, or electric push rods, etc. The second drive module 650 is connected to the scraper 640, and the fifth driver 630 is connected to the second solder cup 620. In use, the fifth driver 630 drives the second solder cup 620 downwards into the molten solder in the solder bath 610, filling the second solder cup 620 completely. When soldering the pin 11, the second drive module 650 drives the scraper 640 downwards to the surface of the molten solder in the solder bath 610 and drives it to move back and forth to scrape off the oxide layer on the surface of the molten solder. Subsequently, the fifth driver 630 drives the second solder cup 620 upwards to a preset height, and the conveying mechanism 400 immerses the pin 11 into the molten solder in the second solder cup 620. This design ensures that the pin 11 is immersed in the molten solder at a consistent height each time, while also allowing the base of the pin 11 to be as close as possible to the surface of the molten solder, increasing the immersion depth and improving the quality of the soldering process. In practical applications, the specific structure of the soldering mechanism 600 can be modified according to the actual usage requirements.
[0044] In some embodiments, the second conveying mechanism 700 includes a third drive module 710, a second motion seat 720, and a second clamping assembly 730. The third drive module 710 is drivenly connected to the second motion seat 720 and is capable of driving the second motion seat 720 to move and / or rotate. The second clamping assembly 730 is disposed on the second motion seat 720 and is used to clamp the coil product 10 in the accommodating cavity 101.
[0045] Understandably, such as Figure 1 , Figure 3 and Figure 8 As shown, the third drive module 710 consists of two drive units, namely a left and right moving unit and a rotating unit. The drive unit can use a rotary cylinder, a motor and a synchronous belt drive, etc., to achieve the corresponding motion drive. The third drive module 710 is driven to the second motion seat 720. Multiple limit blocks 111 are provided in the accommodating cavity 101 at intervals along the left and right direction to accommodate multiple coil products 10. The pins 11 of multiple coil products 10 can be soldered at one time. Multiple second clamping components 730 are correspondingly provided and are all provided on the second motion seat 720. In use, the conveying mechanism 400 positions the box 110 on its side so that the opening of the receiving cavity 101 faces the second conveying mechanism 700. The second clamping assembly 730 clamps the coil-type product 10 in the receiving cavity 101. The conveying mechanism 400 moves the clamped box 110, causing the coil-type product 10 to separate and be removed from the box 110. Subsequently, the third drive module 710 drives the second motion seat 720 to move and rotate, thereby conveying the coil-type product 10 for unloading. In practical applications, the specific structure of the second conveying mechanism 700 can be changed according to actual usage requirements.
[0046] In some embodiments, a blower assembly 220 is provided on the frame 200, and the conveying mechanism 400 can convey the fixture 100 to the blower assembly 220. The blower assembly 220 is used to blow cool the soldered pins 11.
[0047] Understandably, such as Figure 1 and Figure 7 As shown, the blower assembly 220 is located between the fluxing mechanism 500 and the soldering mechanism 600. During use, the conveying mechanism 400 can move the fixture 100 above the blower assembly 220 and hold it there for a preset time. The blower assembly 220 then cools the soldered pins 11 by blowing air, facilitating the cooling and fixing of the molten solder on the pins 11 for easy use. In practical applications, the specific structure of the blower assembly 220 can be customized according to actual usage requirements.
[0048] In some embodiments, a suction assembly 230 is provided on the frame 200. The suction assembly 230 is located on one side of the soldering mechanism 600 and is connected to an exhaust pipe 240. The suction assembly 230 has a suction port 201 facing the soldering mechanism 600.
[0049] Understandably, such as Figure 1 and Figure 7 As shown, the suction assembly 230 is located at the rear of the soldering mechanism 600 and connected to the exhaust pipe 240. The suction port 201 of the suction assembly 230 faces the soldering mechanism 600 to promptly suck up and discharge the fumes generated at the solder pot 610, reducing the possibility of fumes spreading and causing contamination to other mechanisms, and facilitating use. In practical applications, the specific structure of the suction assembly 230 can be set according to actual usage needs.
