Description

Technical Field

[0001] This invention belongs to the field of brazing machine technology, and specifically relates to a brazing machine for workpiece processing with an automatic flux application structure. Background Technology

[0002] Based on the usage scenarios and principles of brazing machines, various situations may arise when using brazing machines for welding, but not limited to the one mentioned below. Existing brazing machines use induced current to heat the workpiece to a certain temperature to melt the solder, thereby wetting and bonding two metals of the same or different materials together.

[0003] CN110722235B discloses a cutting tooth brazing machine, which includes a power control unit and a brazing operation unit. The power control unit includes a power control cabinet, a power supply, and a programmable logic controller (PLC). The power control cabinet has a cavity, and the power supply and the PLC are respectively housed in the power control cabinet. The brazing operation unit includes a base, a worktable, a brazing assembly, and a controller chassis. The worktable is connected to the base, the brazing assembly is disposed on the worktable, and the controller chassis is disposed on the worktable and electrically connected to the brazing assembly and the PLC respectively. The controller chassis is used to control the start and stop of the cutting tooth brazing machine.

[0004] Existing brazing machines for workpiece processing with automatic flux application structures still require manual application of flux during workpiece welding to assist in the welding process. Flux is a chemical substance that helps and promotes the welding process, while also providing protection and preventing oxidation. Manual application is not only inefficient and costly, but it is also prone to uneven application and dead spots, which may lead to inconsistent welding quality. This is especially true for brazing copper workpieces using paste-like neutral flux. Compared to spreading, dipping can make the flux application more even, but dipping can also cause more flux to adhere to areas that do not need to be welded, resulting in waste.

[0005] Based on the problems mentioned above, we found that existing brazing machines have difficulty avoiding these problems at the same time. Even if they can solve them, they still need to immerse the entire welding position, resulting in a waste of flux. Therefore, we propose a brazing machine that can automatically apply flux evenly and avoid waste. Summary of the Invention

[0006] The purpose of this invention is to address the existing brazing machine for workpiece processing with an automatic flux application structure, which has the advantages of automatically applying flux evenly and minimizing waste.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a brazing machine for workpiece processing with an automatic flux coating structure, comprising a main structure of the brazing machine and a base, wherein the main structure of the brazing machine is installed on the front side of the base, a column is bolted to the top of the base, a chuck clamp is bolted to the top of the column, an electric slide rail is bolted to the top of the base, a bracket is drivenly connected to the front side of the electric slide rail, a limit component is bolted to the top of the bracket, and a feeding component is bolted to the right side of the limit component;

[0008] The limiting component includes an outer ring, and two spacer rings are provided on the inner side of the outer ring. The spacer rings are integrally formed with the outer ring. An airbag is installed on the top of the top spacer ring and the bottom of the bottom spacer ring. An air valve is attached to the side of the airbag near the outer ring.

[0009] The feeding assembly includes a side shell, a side frame is bolted to the right side of the side shell, a crankshaft is rotatably connected to the inner side of the side frame, the top of the crankshaft is externally connected to the output end of a control motor, a push cylinder is rotatably connected to the left side of the crankshaft, the outer side of the push cylinder is movably connected to the inner side of the side shell, and a transition shell is bolted to the top of the side shell.

[0010] By adopting the above technical solution, and by setting up a brazing machine main structure with a base, it can be used as a normal brazing equipment. The column and chuck fixture facilitate the installation of the workpiece to be welded, enabling welding operations. The electric slide rail with a bracket facilitates the vertical adjustment of the limiting component. The feeding component with the limiting component facilitates the supply of flux and the limitation of the flux application position. In use, the workpiece is first installed on the chuck fixture, then the electric slide rail, through the bracket, moves the annular limiting component to outside the welding position, and then an external gas supply is connected. The pump inflates the air bladders through the air valves, causing the air bladders to expand and press against the outside of the workpiece. The top and bottom air bladders isolate the flux application areas required for welding inside. Then, the control motor connected to the feeding assembly starts, driving the crankshaft to rotate. The pusher connected to it moves back and forth along the side shell in a linear motion. The flux material injected from the transition shell moves between the two spacers due to the pusher and is injected into the two air bladders to make uniform contact with the flux application areas required for welding, thus achieving the effect of applying flux. This avoids waste caused by applying flux to useless areas and eliminates the need for manual operation, thereby increasing work efficiency.

[0011] The present invention is further configured such that: an external air pump is connected to the air valve, a retaining ring is bolted between the two opposing sides of the spacers, and an overflow pipe is bolted to the inner side of the retaining ring.

[0012] By adopting the above technical solution, and by setting a retaining ring in conjunction with an overflow pipe, a certain resistance can be provided to avoid excess flux from flowing and dripping due to lack of restraint after application, which would cause waste and make it difficult to clean.

[0013] The invention is further configured such that: a hopper is installed on the top of the transition shell, and a sealing plug is bolted to the left side of the pusher cylinder.

[0014] By adopting the above technical solution, the addition of flux to the top of the transition shell can be facilitated by setting a hopper, and the sealing plug can improve the sealing between the structures and prevent the flux from leaking out through the gaps in the structure when the flux is pushed.

[0015] The present invention is further configured such that: an arc segment is bolted to the left side of the side shell, and the left side of the arc segment is bolted to the outer ring.

[0016] By adopting the above technical solution and setting the arc segment, the injection of flux can be guided, so as to reasonably introduce the flux between the two spacer rings.

[0017] The invention is further configured such that a pressure sensor is bolted to the left side of the transition shell.

[0018] Using the above technical solution, by setting a pressure sensor, after the flux is injected between the two airbags, if the pusher continues to push inside the side shell, the pressure inside the cavity will increase because the flux between the airbags has been filled. The flux will then contact the pressure sensor to trigger the external control motor to stop operation and prevent flux from overflowing.

[0019] The present invention is further configured such that: an elastic sheet is bolted to the inner side of the transition shell, and the left side of the elastic sheet is used in conjunction with a pressure sensor.

[0020] By adopting the above technical solution and setting an elastic sheet, the flux can be prevented from directly contacting the pressure sensor, which would cause difficulties in cleaning and accidental contact. The deformation of the elastic sheet can replace the flux to indirectly contact the pressure sensor.

[0021] The present invention is further configured such that: an externally threaded pipe is bolted to the top of the transition shell, and the outer side of the externally threaded pipe is threadedly connected to the hopper.

[0022] By adopting the above technical solution and setting an external threaded pipe, it is easy to continue connecting the transition shell and the hopper, so as to facilitate the installation of the structure and the continued addition of flux.

[0023] The present invention is further configured such that: a check valve is bolted to the inner side of the external threaded pipe, and the top of the check valve is used in conjunction with the hopper.

[0024] By adopting the above technical solution and setting a check valve, the flux can be prevented from flowing back into the hopper under pressure.

[0025] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a flux application auxiliary system; the flux application auxiliary system includes a central control module, the input terminal of the central control module is unidirectionally electrically connected to a data analysis module, the input terminal of the data analysis module is unidirectionally electrically connected to an input module, the input terminal of the data analysis module is unidirectionally electrically connected to an interrupt module, the input terminal of the interrupt module is unidirectionally electrically connected to the central control module, the output terminal of the central control module is unidirectionally electrically connected to a range limiting module, the output terminal of the central control module is unidirectionally electrically connected to a displacement module, the output terminal of the central control module is unidirectionally electrically connected to a feeding module, and the input terminal of the feeding module is unidirectionally electrically connected to the interrupt module.

[0026] Using the above technical solution, the welding position of batch workpieces can be set by setting the input module to determine the position of the displacement module and the range limiting module. The interrupt module is used to pause the supply of flux after the flux is completely applied. The feeding module is used to continuously supply flux material. The vertical position of the welding application is adjusted by the displacement module.

[0027] The present invention is further configured such that: the interrupt module is a pressure sensor, the range limiting module is an external air pump, the displacement module is an electric slide rail, and the feeding module is an external drive motor.

[0028] By adopting the above technical solution, by setting an external air pump as a range limiting module, the amount of gas filled into the airbag can be easily controlled; by setting an electric slide rail as a displacement module, the vertical height of the structure can be easily adjusted; and by setting an external drive motor as a feeding module, the supply of flux can be easily controlled.

[0029] In summary, the present invention has the following beneficial effects:

[0030] By setting up the main structure of the brazing machine in conjunction with the base, it can be used as a normal brazing device. The column and chuck fixture facilitate the installation of the workpiece to be welded, enabling welding operations. The electric slide rail, in conjunction with the bracket, allows for easy vertical adjustment of the limiting component. The feeding component, in conjunction with the limiting component, facilitates the supply of flux and the limitation of the flux application area. In use, the workpiece is first mounted on the chuck fixture. Then, the electric slide rail, via the bracket, moves the annular limiting component to the outside of the welding position. Finally, an external air pump delivers air... The valve inflates the air bladder, causing it to expand and press against the outside of the workpiece. The top and bottom air bladders isolate the flux application area required for welding. Then, the control motor connected to the feeding assembly starts, driving the crankshaft to rotate. The pusher connected to it moves back and forth along the side shell. The flux material injected from the transition shell moves between the two spacers due to the pusher and is injected into the two air bladders to make uniform contact with the flux application area required for welding, thus achieving the effect of applying flux. This avoids waste caused by applying flux to useless areas and eliminates the need for manual operation, thereby increasing work efficiency. Attached Figure Description

[0043] The present invention will be further described in detail below with reference to the accompanying drawings.

[0044] Example 1:

[0045] refer to Figure 1-9 A brazing machine for workpiece processing with an automatic flux application structure includes a main structure 1 and a base 2. The main structure 1 is installed on the front side of the base 2. A column 4 is bolted to the top of the base 2. A chuck clamp 5 is bolted to the top of the column 4. An electric slide rail 6 is bolted to the top of the base 2. A bracket 7 is driven to the front side of the electric slide rail 6. A limit component 8 is bolted to the top of the bracket 7. A feeding component 9 is bolted to the right side of the limit component 8.

[0046] The limiting component 8 includes an outer ring 801, with two spacer rings 802 integrally formed on the inner side of the outer ring 801. Airbags 803 are installed at the top of the top spacer ring 802 and the bottom of the bottom spacer ring 802. An air valve 804 is attached to the side of the airbag 803 closest to the outer ring 801. By using the main structure 1 of the brazing machine in conjunction with the base 2, it can be used as a normal brazing machine. The column 4 and chuck clamp 5 facilitate the installation of the workpiece to be welded, enabling welding operations. The electric slide rail 6, in conjunction with the bracket 7, facilitates the movement of the limiting component 8 along the vertical direction. To adjust the position, the workpiece is first installed on the chuck fixture 5. Then, the electric slide rail 6 moves the annular limiting component 8 to the outside of the welding position via the bracket 7. Then, the external air pump inflates the air bag 803 through the air valve 804. At this time, the air bag 803 expands and presses against the outside of the workpiece. The top air bag 803 and the bottom air bag 803 separate the flux application position required for welding inside. Then, the feeding component 9 injects the flux material between the two spacer rings 802, so that the displacement between the two air bags 803 makes even contact with the flux application position required for welding, so as to achieve the effect of applying flux.

[0047] like Figure 2 and Figure 8 As shown, the air valve 804 is connected to an external air pump. A retaining ring 10 is bolted between the two opposing sides of the spacers 802. An overflow pipe 11 is bolted to the inner side of the retaining ring 10. By setting the retaining ring 10 in conjunction with the overflow pipe 11, a certain resistance can be provided to avoid excess flux from flowing and dripping due to lack of restraint after the coating is completed, which would cause waste and make it difficult to clean.

[0048] Brief description of the usage process: First, the welding material is loaded into the main structure 1 of the brazing machine, and the main structure 1 is preheated. The workpiece to be welded can be easily installed through the column 4 and the chuck clamp 5. At this time, the chuck clamp 5 should be located slightly lower outside the column 4. The electric slide rail 6, which acts as the displacement module 306, drives the limiting component 8 to adjust its position in the vertical direction and position it outside the application position. Then, the external air pump, which acts as the range limiting module 305, inflates the air bag 803 through the air valve 804. At this time, the air bag 803 expands and presses against the outside of the workpiece. The top air bag 803 and the bottom air bag 803 isolate the flux application position required for welding from the outside. Then, the feeding module of the feeding component 9... The 307 drive injects flux material between the two spacer rings 802, causing them to shift between the two airbags 803 and make uniform contact with the flux application position required for welding. After filling, the flux will press against the pressure sensor 15, which is the interrupt module 304, to stop the feeding of the feeding module 307. Then the airbags 803 depress, so that the limiting component 8 no longer contacts the workpiece. The electric slide rail 6 drives the mating bracket 7 to descend vertically, so that its horizontal height is below the chuck clamp 5, so as to move the limiting component 8 down. Then the main structure 1 of the brazing machine uses high-frequency current to generate heat energy through the electrodes to heat the workpiece to the melting point. Then, the weld point is formed by controlling the current density.

[0049] Example 2:

[0050] refer to Figure 1-9 A brazing machine for workpiece processing with an automatic flux application structure includes a main structure 1 and a base 2. The main structure 1 is installed on the front side of the base 2. A column 4 is bolted to the top of the base 2. A chuck clamp 5 is bolted to the top of the column 4. An electric slide rail 6 is bolted to the top of the base 2. A bracket 7 is driven to the front side of the electric slide rail 6. A limit component 8 is bolted to the top of the bracket 7. A feeding component 9 is bolted to the right side of the limit component 8.

[0051] The feeding assembly 9 includes a side shell 901, a side frame 902 is bolted to the right side of the side shell 901, a crankshaft 903 is rotatably connected to the inner side of the side frame 902, the top of the crankshaft 903 is externally connected to the output end of the control motor, a push cylinder 904 is rotatably connected to the left side of the crankshaft 903, the outer side of the push cylinder 904 is movably connected to the inner side of the side shell 901, and a transition shell 905 is bolted to the top of the side shell 901.

[0052] The control motor connected to the feeding assembly 9 starts and drives the crankshaft 903 to rotate. The pusher 904 connected to it moves back and forth along the side shell 901. The flux material injected from the transition shell 905 moves between the two spacer rings 802 due to the pusher 904 and is injected into the limiting assembly 8 to facilitate the application of flux to the workpiece.

[0053] like Figure 3 As shown, a hopper 12 is installed on the top of the transition shell 905, and a sealing plug 13 is bolted to the left side of the pusher 904. By setting the hopper 12, it is convenient to add flux to the top of the transition shell 905. The sealing plug 13 can improve the sealing between the structures and prevent flux from leaking out through the gaps in the structures when the flux is pushed.

[0054] like Figure 9 As shown, an arc segment 14 is bolted to the left side of the side shell 901. The left side of the arc segment 14 is bolted to the outer ring 801. By setting the arc segment 14, the injection of flux can be guided so that the flux can be reasonably introduced between the two spacer rings 802.

[0055] like Figure 9 As shown, a pressure sensor 15 is bolted to the left side of the transition shell 905. By setting the pressure sensor 15, after flux is injected between the two airbags 803, if the pusher 904 continues to push inside the side shell 901, the pressure inside the cavity will increase because the flux between the airbags 803 has been filled. The flux will contact the pressure sensor 15 to trigger the external control motor to stop the operation and prevent flux from overflowing.

[0056] like Figure 9 As shown, an elastic sheet 16 is bolted to the inner side of the transition shell 905. The left side of the elastic sheet 16 is used in conjunction with the pressure sensor 15. By setting the elastic sheet 16, the flux can be prevented from directly contacting the pressure sensor 15, which would make it difficult to clean and cause accidental contact. The deformation of the elastic sheet 16 can replace the flux to indirectly contact the pressure sensor 15.

[0057] like Figure 6 As shown, the top of the transition shell 905 is bolted with an external threaded pipe 17, and the outer side of the external threaded pipe 17 is threadedly connected to the hopper 12. By setting the external threaded pipe 17, it is easy to continue to connect the transition shell 905 and the hopper 12, so as to facilitate the installation of the structure and the continued addition of flux.

[0058] like Figure 6 As shown, a check valve 18 is bolted to the inside of the external threaded pipe 17. The top of the check valve 18 is used in conjunction with the hopper 12. By setting the check valve 18, the flux can be prevented from flowing back into the hopper 12 under pressure.

[0059] Brief description of the operation process: During normal use, the external control motor starts, driving the crankshaft 903 to drive the pusher 904 to reciprocate linearly along the side shell 901. The flux in the hopper 12 enters the transition shell 905 through the check valve 18. The flux material injected from the transition shell 905 moves between the two spacer rings 802 due to the push of the pusher 904 and is injected into the limiting component 8 to facilitate the application of flux to the workpiece. If the flux between the airbags 803 is already full, the pressure inside the cavity will increase. The flux will fill the elastic sheet 16, deform it, and contact the pressure sensor 15 to trigger the external control motor to stop the operation and prevent flux from overflowing.

[0060] Example 3:

[0061] Please refer to Figure 10 A flux application auxiliary system includes a central control module 301. The input terminal of the central control module 301 is unidirectionally electrically connected to a data analysis module 302. The input terminal of the data analysis module 302 is unidirectionally electrically connected to an input module 303. The input terminal of the data analysis module 302 is unidirectionally electrically connected to an interrupt module 304. The input terminal of the interrupt module 304 is unidirectionally electrically connected to the central control module 301. The output terminal of the central control module 301 is unidirectionally electrically connected to a range limiting module 305. The output terminal of the central control module 301 is unidirectionally electrically connected to a displacement module 306. The output terminal of the central control module 301 is unidirectionally electrically connected to a feeding module 307. The input terminal of the feeding module 307 is unidirectionally electrically connected to the interrupt module 304. The interrupt module 304 is a pressure sensor 15. The range limiting module 305 is an external air pump. The displacement module 306 is an electric slide rail 6. The feeding module 307 is an external drive motor.

[0062] In this embodiment, the welding position of the batch of workpieces is first set by the input module 303. During normal use, the displacement module 306 adjusts the position of the range limiting module 305 according to the set position. The feeding module 307 is started to continuously supply flux material. The vertical position of the welding coating is adjusted by the displacement module 306. By setting an external air pump as the range limiting module 305, the amount of gas filled into the airbag 803 can be easily controlled. The interrupt module 304 is used to pause the flux supply after the flux is completely applied. The electric slide rail 6 as the displacement module 306 can facilitate the adjustment of the vertical height of the structure. The external drive motor as the feeding module 307 can facilitate the drive control of the flux supply.

[0063] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
