[0002] In the production process of inductors, pin surface treatment is a key link to ensure the quality of subsequent welding and the reliability of electrical connection. As the only bridge connecting inductors and circuit boards, the solderability of the pin surface and the quality of the plating layer directly determine the long-term stability of the mechanical strength and electrical performance of the entire electronic assembly. If the pin has oxidation, contamination or paint residue, it is easy to cause problems such as false welding, cold welding or insufficient welding strength, thereby causing increased circuit impedance and increased signal transmission loss, and even causing early failure of the equipment. In particular in the fields of high reliability such as automotive electronics and aerospace, the uniformity, adhesion and corrosion resistance of the pin plating layer are extremely strict.

When working, the vibrating disc adjusts the direction of the inductor coil and sends it to the conveying mechanism, the conveying mechanism sends the inductor coil through the paint stripper spraying device for paint stripping agent treatment, then the conveying mechanism sends the inductor coil through the hot air treatment device for blowing and heating treatment, then the inductor coil is sent to the brush paint removal device for paint stripping treatment, the inductor coil after paint stripping is sent to the flux spraying device by the conveying mechanism for flux spraying treatment, and finally the inductor coil is sent to the wave soldering machine for soldering treatment.

[0074] Further, the paint stripping clamping mechanism 32 comprises a clamping fixed frame 321 fixed on one side of the sliding seat, a clamping lifting seat 322 liftable on the clamping fixed frame 321, a clamping clamping jaw 323 rotatable on the clamping lifting seat 322, a first clamping cylinder 324 for driving the clamping lifting seat 322 to vertically lift relative to the clamping fixed frame 321, a rotating motor 325 for driving the clamping clamping jaw 323 to rotate relative to the clamping lifting seat 322, and a second clamping cylinder 326 for driving the clamping clamping jaw 323 to open and close to clamp or release the inductor coil 200.

[0075] When the first positioning cylinder 313 drives the positioning seat 311 to move, driving the positioning column 3121 on the positioning rod 312 to move to the paint stripping station 302, the first clamping cylinder 324 drives the clamping lifting seat 322 to descend, and then the second clamping cylinder 326 drives the clamping clamping jaw 323 to close to grab the inductor coil 200, and then the first clamping cylinder 324 drives the clamping lifting seat 322 to rise to a predetermined height, so that the laser paint stripping mechanism 33 can strip the pins 220 of the inductor coil 200 clamped by the clamping clamping jaw 323. When stripping, the clamping clamping jaw 323 is driven to rotate by the rotating motor 325, so that the laser paint stripping mechanism 33 can comprehensively strip the part of the pin 220 that needs to be stripped, ensuring the stripping quality.

[0076] Further, referring to Figure 6 , Figure 7 and Figure 8 , the laser paint stripping mechanism 33 comprises a laser paint stripping fixed frame 331, a laser 332 fixed on the laser paint stripping fixed frame 331 and located above the paint stripping clamping mechanism 32, a mounting frame 333 provided on one side of the laser paint stripping fixed frame 331, a protective box 334 slidably provided on the mounting frame 333, and a paint stripping cylinder 335 provided on the mounting frame 333 for driving the protective box 334 to move towards or away from the paint stripping clamping mechanism 32. The side wall of the protective box 334 is provided with a side opening 3341 for the clamping end of the paint stripping clamping mechanism 32 to enter, and the top of the protective box 334 is provided with a top opening 3342 for the laser emitted by the laser 332 to pass through.

[0077] When the clamping jaw 323 clamps the inductor coil 200 to be stripped and rises to a preset height under the drive of the first clamping cylinder 324, the stripping cylinder 335 drives the protective box 334 to move towards the stripping clamping mechanism 32, so that the clamping end of the stripping clamping mechanism 32 (i.e. the clamping jaw 323 and the inductor coil 200 clamped thereby) enters the protective box 334 through the side opening 3341, and then the laser 332 works, the laser emitted by the laser 332 enters the protective box 334 through the top opening 3342 of the protective box 334 and irradiates on the pin 220 of the inductor coil 200 clamped by the clamping jaw 323, so as to realize stripping of the pin 220. Stripping in the protective box 334 can effectively prevent the laser from leaking to cause harm to the operator, and can avoid interference of external environmental factors on the stripping process, so as to ensure stability and safety of the stripping environment.

[0078] Further, referring to Figure 4 、 Figure 9 and Figure 10 , the tinning module 40 comprises a tinning mechanism 41, the tinning mechanism 41 comprises a tinning tank 411, a tinning seat 412 fixedly arranged above the tinning tank 411, and a lifting assembly 413 for driving the tinning tank 411 and / or the tinning seat 412 to move up and down, the tinning tank 411 contains tin liquid, the tinning seat 412 is provided with a tinning opening 4121 for positioning the inductor coil 200, the inductor coil 200 is accommodated in the tinning opening 4121 and the pin 220 of the inductor coil 200 extends from the bottom of the tinning opening 4121, and the lifting assembly 413 is used for driving at least one of the tinning tank 411 and the tinning seat 412 to move up and down, so that the stripped part of the pin 220 is immersed in the tin liquid.

[0079] When the transfer mechanism 50 transfers the inductor coil 200 after stripping to the tinning opening 4121 on the tinning seat 412, the pin 220 of the inductor coil 200 after stripping extends from the bottom of the tinning opening 4121, at this time, at least one of the tinning tank 411 and the tinning seat 412 is driven by the lifting assembly 413 to move up and down, so that the stripped part of the pin 220 can be immersed in the tin liquid in the tinning tank 411, so that the surface of the pin 220 after stripping is plated with a layer of metal tin.

[0080] It should be noted that the tinning process adopted by the present application is a "hot dipping process", the tinning tank 411 is provided with an electric heating assembly and a temperature sensor, the electric heating assembly is used for heating the tin liquid in the tinning tank 411 to keep it within the required temperature range, and the temperature sensor monitors the temperature of the tin liquid in real time and feeds back the temperature information to the control mechanism 70. The control mechanism 70 accurately controls the working state of the electric heating assembly according to the information fed back by the temperature sensor, so as to ensure that the temperature of the tin liquid is always stable in the appropriate range, thereby ensuring the consistency and stability of the tinning quality.

[0081] Further, the tinning mechanism 41 further comprises a tinning pool 414 and a tinning fixing frame 415, the tinning tank 411 is vertically arranged in the tinning pool 414, the tinning fixing frame 415 is arranged on the side of the tinning pool 414 close to the paint stripping module 30, and the tinning seat 412 is fixed on the tinning fixing frame 415. The lifting assembly 413 is used to drive the tinning tank 411 to move relative to the tinning pool 414 towards or away from the tinning seat 412, so that the part of the pin 220 of the inductor coil 200 which has completed paint stripping enters the tin liquid in the tinning tank 411.

[0082] It should be noted that the tin liquid pool contains tin liquid, and when the tinning tank 411 is in the initial position, the top of the tinning tank 411 is below the tin liquid level of the tin liquid pool, so that the inside of the tinning tank 411 is filled with tin liquid. When the lifting assembly 413 drives the tinning tank 411 to rise, the tinning tank 411 rises with the tin liquid in its inside and contacts the pin 220 of the inductor coil 200 on the tinning seat 412, so that the part of the pin 220 which has completed paint stripping is plated with a layer of tin.

[0083] In other embodiments, the lifting assembly 413 can also be arranged to drive the tinning seat 412 to vertically lift relative to the tinning tank 411, and the tinning pool 414 can be selected to be deleted according to actual conditions, which is not limited here.

[0084] Further, the lifting assembly 413 comprises a tinning lifting cylinder 4131 vertically arranged on one side of the tinning pool 414 and a connecting plate 4132 arranged on the piston rod of the tinning lifting cylinder 4131, the tinning lifting cylinder 4131 is arranged on the same side of the tinning fixing frame 415, and the tinning connecting plate 4132 is used to connect the piston rod of the tinning lifting cylinder 4131 and the tinning tank 411, so that the tinning lifting cylinder 4131 can drive the tinning tank 411 to move relative to the tinning pool 414 towards or away from the tinning seat 412.

[0085] When the transfer mechanism 50 transfers the inductor coil 200 which has completed paint stripping to the tinning port 4121 on the tinning seat 412, the part of the pin 220 of the inductor coil 200 which has completed paint stripping extends from the bottom of the tinning port 4121. At this time, the connecting plate 4132 is driven to rise by the lifting cylinder, and the tinning tank 411 is driven to move relative to the tinning pool 414 towards the tinning seat 412, so that the part of the pin 220 which has completed paint stripping can be immersed in the tin liquid in the tinning tank 411, and tinning is completed.

[0086] In addition, the tinning mechanism 41 further comprises a first inductor 416 arranged on the tinning seat 412 for sensing the inductor coil 200, which can accurately detect whether the inductor coil 200 is placed in the tinning opening 4121. When the first inductor 416 detects that the inductor coil 200 has been correctly placed in the tinning opening 4121, a signal will be sent to the control mechanism 70, and the control mechanism 70 will only control the lifting cylinder to start driving the tinning tank 411 to rise for tinning operation after receiving the signal. This effectively avoids tinning failure or equipment failure caused by the inductor coil 200 not being placed in place, and improves the reliability and stability of the tinning process.

[0087] Further, referring to Figure 9 and Figure 11 , the tinning module 40 further comprises a tinning mechanism 42 for removing the oxide film or solidified material on the surface of the tinning pool 414.

[0088] It should be noted that the surface of the tin liquid is prone to form an oxide film or solidified material after a long time of standing or contact with air. If this layer of material is not removed in time, it will affect the tinning quality of the inductor coil 200 pin 220, resulting in uneven plating, poor adhesion and other problems. The tinning mechanism 42 is designed to solve this problem. In actual work process, when the tinning module 40 performs tinning operation, the tinning mechanism 42 will start automatically according to the set time interval or according to the surface state of the tin liquid, for example, before the lifting cylinder drives the tinning tank 411 to rise, the tinning mechanism 42 starts and cleans the surface of the tin liquid, so that the pin 220 of the inductor coil 200 can contact clean and uniform tin liquid every time tinning, thereby greatly improving the quality and efficiency of tinning.

[0089] Further, the tinning mechanism 42 comprises a tinning seat 421 slidingly arranged on one side of the tinning pool 414, a scraper 422 liftably arranged on the tinning seat 421, a waste collection groove 423 arranged at one end of the tinning pool 414 in the length direction, a first tinning cylinder 424 for driving the tinning seat 421 to move along the length direction of the tinning pool 414, and a second tinning cylinder 425 for driving the scraper 422 to vertically lift relative to the tinning seat 421 so that the bottom end of the scraper 422 contacts the surface of the tin liquid in the tinning pool 414.

[0090] When tin scraping is needed, the tin scraping seat 421 is driven to vertically descend by the second tin scraping cylinder 425, so that the bottom end of the scraping plate 422 is in contact with the surface of the tin liquid and at least partially immersed in the tin liquid, and then the tin scraping seat 421 is driven to move along the length direction of the tinning pool 414 by the first tin scraping cylinder 424, so that the scraping plate 422 is moved, thereby enabling the scraping plate 422 to scrape and push the oxidation film or solidified substance on the surface of the tin liquid into the waste residue collection groove 423. Specifically, during the movement of the scraping plate 422, the bottom of the scraping plate 422 is in contact with the oxidation film or solidified substance on the surface of the tin liquid, and as the scraping plate 422 moves, the impurities are peeled off from the surface of the tin liquid and finally pushed into the waste residue collection groove 423 at one end of the tinning pool 414.

[0091] Further, referring to Figure 9 and Figure 10 , the desmearing module 30 and the tinning module 40 are further provided with a fluxing buffer station 80, the fluxing buffer station 80 comprising a buffer assembly 81 and a flux supply assembly 82, the buffer assembly 81 being used for temporarily storing the inductor coil 200 after desmearing, and the flux supply assembly 82 being used for coating the pins 220 of the inductor coil 200 temporarily stored in the buffer assembly 81 with flux.

[0092] Through the provision of the fluxing buffer station 80, a buffer area can be constructed between the desmearing and tinning processes, so as to avoid production stagnation caused by inconsistent rhythm of the processes. Through the provision of the buffer assembly 81, the inductor coil 200 after desmearing can be ensured to orderly wait for entering the tinning link. The flux supply assembly 82 is used for coating the pins 220 of the inductor coil 200 after desmearing with a layer of flux, which helps to improve the tinning quality, better combine the tin layer with the pins 220, and enhance the reliability and stability of tinning.

[0093] Further, the buffer assembly 81 comprises a buffer rack 811 fixed on the machine body 10 and a buffer seat 812 provided on the buffer rack 811, the buffer rack 811 being located on the side of the tinning module 40 facing the desmearing module 30, and the buffer seat 812 being provided with a through buffer groove 8121, when the moving mechanism 50 moves the inductor coil 200 to the buffer groove 8121 on the buffer seat 812, the pins 220 of the inductor coil 200 extend from the bottom of the buffer groove 8121.

[0094] The flux supply assembly 82 comprises a flux pool 821, a flux tank 822 which is vertically movable in the flux pool 821, and a flux lifting cylinder 823 for driving the flux tank 822 to vertically move relative to the flux pool 821 so as to immerse the desoldered pins 220 of the inductor coil 200 on the storage seat 812 into the flux tank 822. The flux pool 821 is located at the side of the storage rack 811 which faces the tinning module 40, and contains flux therein. The flux tank 822 is located directly below the storage seat 812, and is initially located below the liquid level of the flux in the flux pool 821 so as to fill the flux tank 822 with flux. Then, the flux tank 822 is driven by the flux lifting cylinder 823 to move relative to the flux pool 821 towards the storage seat 812, so as to immerse the desoldered pins 220 of the inductor coil 200 on the storage seat 812 into the flux and coat the desoldered pins 220 with flux.

[0095] In addition, the flux supply assembly 82 further comprises a second inductor 824 which is fixed on the storage seat 812 and is used for inducting the inductor coil 200. The second inductor 824 is electrically connected to the control mechanism 70. When the second inductor 824 inducts the inductor coil 200 placed in the storage seat 812, the second inductor 824 sends a signal to the control mechanism 70. After receiving the signal, the control mechanism 70 controls the flux lifting cylinder 823 to drive the flux tank 822 to move relative to the flux pool 821 towards the storage seat 812, so as to immerse the desoldered pins 220 of the inductor coil 200 on the storage seat 812 into the flux.

[0096] Further, referring to Figure 4 , Figure 9 and Figure 12 , the transfer mechanism 50 comprises a transfer fixing rack 51, and a first transfer assembly 52, a second transfer assembly 53 and a third transfer assembly 54 which are arranged on the transfer fixing rack 51. The first transfer assembly 52 is used for transferring the inductor coil 200 from the desoldering module 30 to the flux storage work station 80. The second transfer assembly 53 is used for transferring the inductor coil 200 from the flux storage work station 80 to the tinning mechanism 41. The third transfer assembly 54 is used for transferring the inductor coil 200 from the tinning mechanism 41 to the material collecting mechanism 60.

[0097] In operation, firstly, the first transfer assembly 52 picks up the inductor coil 200 from the paint stripping module 30 and transfers it to the buffer seat 812 of the fluxing buffer station 80, at this time, the pins 220 of the inductor coil 200 extend from the bottom of the buffer groove 8121. Then, the fluxing lifting cylinder 823 drives the fluxing groove 822 to ascend relative to the fluxing pool 821, so that the pins 220 of the inductor coil 200 are immersed in the fluxing groove 822, and the pins 220 are coated with flux. Subsequently, the second transfer assembly 53 picks up the inductor coil 200 coated with flux from the fluxing buffer station 80 and transfers it to the tinning mechanism 41. In the tinning mechanism 41, the inductor coil 200 is tinned. Finally, the third transfer assembly 54 transfers the tinned inductor coil 200 from the tinning mechanism 41 to the material collecting mechanism 60, and the entire paint stripping and tinning process of the inductor coil 200 is completed.

[0098] In addition, in order to synchronize the movement of the first transfer assembly 52, the second transfer assembly 53 and the third transfer assembly 54, the transfer mechanism 50 further comprises a transfer sliding plate 55 slidingly arranged on the transfer fixed frame 51, and a transfer linear motor 56 for driving the transfer sliding plate 55 to move, and the first transfer assembly 52, the second transfer assembly 53 and the third transfer assembly 54 are arranged on the transfer sliding plate 55. In operation, the transfer linear motor 56 drives the transfer sliding plate 55 to move along the length direction of the transfer fixed frame 51, so that the first transfer assembly 52 transfers the inductor coil 200 after paint stripping to the buffer seat 812, the second transfer assembly 53 transfers the inductor coil 200 after flux coating to the tinning seat, and the third transfer assembly 54 transfers the inductor coil 200 after tinning to the material collecting mechanism, so that the three processes are synchronized. This greatly improves the production efficiency and reduces the waiting time between different processes.

[0099] Specifically, the first transfer assembly 52 comprises a first transfer fixed frame 521 fixedly arranged on the transfer sliding plate 55, a first transfer lifting plate 522 vertically arranged on the bottom side of the first transfer fixed frame 521, a first transfer fixed plate 523 fixedly arranged on the first transfer lifting plate 522, a first transfer clamping jaw 524 arranged on the first transfer fixed plate 523, a first transfer motor 525 for driving the first transfer lifting plate 522 to vertically lift, a second transfer motor 526 for driving the first transfer fixed plate 523 to rotate, and a first clamping jaw cylinder 527 for driving the first transfer clamping jaw 524 to open and close. In this embodiment, a screw nut seat or the like is arranged between the first transfer motor 525 and the first transfer lifting plate 522, so that the first transfer motor 525 can drive the first transfer lifting plate 522 to vertically lift when the first transfer motor 525 works. This is a conventional technology in the field, and will not be described in detail here.

[0100] In operation, the first transfer motor 525 drives the first transfer lifting plate 522 to move up and down in the vertical direction, so that the first transfer fixed plate 523 and the first transfer clamping jaw 524 thereon reach the appropriate height. Then, the second transfer motor 526 drives the first transfer fixed plate 523 to rotate, so as to adjust the angle of the first transfer clamping jaw 524, so that the inductor coil 200 that has completed the paint removal at the transfer station 303 can be accurately grabbed. At this time, the first clamping jaw cylinder 527 drives the first transfer clamping jaw 524 to open and close, so as to stably clamp the inductor coil 200 that has completed the paint removal. When the transfer linear motor 56 drives the transfer sliding plate 55 to move, the inductor coil 200 is transferred to the buffer seat 812. Before the inductor coil 200 is transferred to the buffer seat 812, the second transfer motor 526 rotates again to adjust the posture of the inductor coil 200 on the first transfer clamping jaw 524, so as to prepare for the subsequent process (soldering flux coating).

[0101] The second transfer assembly 53 includes a second transfer fixed frame 531 fixedly arranged on the transfer sliding plate 55, a second transfer cylinder 532 vertically arranged on the second transfer fixed frame 531, a second transfer fixed plate 533 arranged on the piston rod of the second transfer cylinder 532, a second transfer clamping jaw 534 arranged on the second transfer fixed plate 533, and a second clamping jaw cylinder 535 for driving the second transfer clamping jaw 534 to open and close. The second transfer cylinder 532 is used to drive the second transfer fixed plate 533 to vertically descend, so as to drive the second transfer clamping jaw 534 to descend, so that the second transfer clamping jaw 534 can grab and transfer the inductor coil 200 on the buffer seat 812 to the tinning seat 412.

[0102] The third transfer assembly 54 has the same structure as the second transfer assembly 53, and will not be described in detail here.

[0103] In addition, the transfer mechanism 50 further includes a protective cover 57, and the second transfer assembly 53 and the third transfer assembly 54 are located in the protective cover 57. The sidewall of the protective cover 57 is provided with an access opening 571 for the first transfer assembly 52 to enter and exit. Through the arrangement of the protective cover 57, it can effectively prevent foreign matter, dust and the like from falling on the inductor coil 200 during the transfer process, so as to avoid pollution to the inductor coil 200, ensure the cleanliness of the inductor coil 200 during the paint removal and tinning process, and further improve the quality and yield of the inductor tinning.

[0104] Further, the material collecting assembly includes a material collecting fixed plate 61 and a material collecting rod 62 arranged on the material collecting fixed plate 61. The material collecting fixed plate 61 is located on the side of the tinning module 40 away from the paint removal module 30. The machine body 10 is provided with a discharging opening corresponding to the position of the material collecting rod 62. The material collecting rod 62 is arranged in a substantially Z-shaped manner, one end of which is fixedly connected to the material collecting fixed plate 61, and the other end extends towards the paint removal module 30.

[0105] In other embodiments, the material receiving rod 62 can also be provided in other shapes, which are not limited herein.

[0106] When collecting the material, the third transfer assembly 54 transfers the tinned inductor coil 200 to the material receiving rod 62, and the material receiving rod 62 stores and collects the inductor coil 200, thereby achieving the collection of the inductor coil 200.

[0107] The second aspect of the embodiment provides an inductor coil tinning method, which refers to Figure 13 based on the inductor coil tinning machine as described above, comprising the following steps:

[0109] 102. The paint removal positioning and conveying mechanism 31 of the paint removal module 30 positions the inductor coil 200 and conveys the inductor coil 200 to the paint removal clamping mechanism 32;

[0110] 103. The paint removal clamping mechanism 32 clamps the inductor coil 200, and then the laser paint removal mechanism 33 performs laser paint removal on the pin 220 of the inductor coil 200 clamped by the paint removal clamping mechanism 32;

[0111] 104. The paint removal clamping mechanism 32 drives the inductor coil 200 to rotate, so that the laser paint removal mechanism 33 can comprehensively remove the paint from the part of the pin 220 of the inductor coil 200 that needs to be removed;

[0112] 105. The paint removal positioning and conveying mechanism 31 conveys the inductor coil 200 whose pin 220 has been removed to the transfer mechanism 50;

[0113] 106. The transfer mechanism 50 transfers the inductor coil 200 to the soldering flux buffer station 80, which buffers the inductor coil 200 and applies soldering flux to the part of the pin 220 that has been removed;

[0114] 107. The transfer mechanism 50 transfers the inductor coil 200 whose pin 220 has been applied with soldering flux to the tinning module 40, which tins the part of the pin 220 of the inductor coil 200 that has been applied with soldering flux;

[0115] 108. The transfer mechanism 50 transfers the tinned inductor coil 200 to the material receiving mechanism 60, thereby completing the material collection.

[0116] Working principle: When working, the feeding mechanism 20 orderly supplies the inductor coil 200 to be processed to the paint removal positioning and conveying mechanism 31 of the paint removal module 30, the paint removal positioning and conveying mechanism 31 of the paint removal module 30 precisely positions the inductor coil 200 and stably conveys it to the paint removal clamping mechanism 32. The paint removal clamping mechanism 32 clamps the inductor coil 200, and then the laser paint removal mechanism 33 performs laser paint removal on the pin 220 of the clamped inductor coil 200. During the paint removal process, the inductor coil 200 is driven to rotate by the paint removal clamping mechanism 32, so that the laser can fully cover the part of the pin 220 that needs to be removed, ensuring that the paint removal is complete. After the paint removal of the pin 220 is completed, the paint removal positioning and conveying mechanism 31 conveys the inductor coil 200 to the transfer mechanism 50. The transfer mechanism 50 transfers the inductor coil 200 to the fluxing buffer station 80. In the fluxing buffer station 80, the inductor coil 200 is temporarily stored, and at the same time, the flux supply assembly 82 applies flux to the part of the pin 220 that has completed paint removal, preparing for subsequent tin plating. Then, the transfer mechanism 50 transfers the inductor coil 200 that has completed flux application to the tin plating module 40. The tin plating module 40 tin plates the part of the pin 220 of the inductor coil 200 that has been coated with flux, forming a uniform and dense tin layer. Finally, the transfer mechanism 50 transfers the inductor coil 200 after tin plating to the material receiving mechanism 60, completing the entire feeding process.
