Description

Technical Field

[0001] This invention relates to the field of inductor manufacturing, and more specifically, to an inductor manufacturing apparatus. Background Technology

[0002] In the process of inductor production, the conductive contacts need to be soldered. Current automatic soldering equipment mainly uses a transfer device to move the workpiece between the loading station, flux application station, soldering station, and unloading station to achieve automatic soldering. However, the current transfer device mainly uses linear motion, which means that after the workpiece is processed and unloaded, the transfer device needs to move from the unloading station to the loading station to reset and pick up and transfer the next batch of workpieces. Although it can achieve a high degree of automation, there is still room for optimization and improvement in the structure and layout of the operation. Summary of the Invention

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 4As shown in the figure, a specific embodiment of the present invention discloses an inductor production equipment, including a discharge device 110, a flux supply device 120, a solder melt supply device 200, a collection box 130, a switching device 300, a pushing structure 140, and a scraping structure 150 mounted on a frame; the discharge device 110, flux supply device 120, solder melt supply device 200, and collection box 130 are sequentially distributed around the center of the switching device 300; the pushing structure 140 is located above the solder melt supply device 200; and the scraping structure 150... The structure 150 is located above the collection box 130; the switching device 300 is equipped with four material-carrying mechanisms 310, which can be adjusted to drive multiple material-carrying mechanisms 310 to rotate between the discharge device 110, the flux supply device 120, the solder liquid supply device 200, and the collection box 130; the workpiece is loaded at the discharge device; the workpiece is coated with flux at the flux supply device; the pushing structure pushes the material-carrying mechanism towards the solder liquid supply device to complete the soldering of the workpiece; the scraping structure is used to scrape the workpiece from the material-carrying mechanism to the collection box.

[0041] The aforementioned inductor production equipment uses a switching device to drive the workpiece to rotate between multiple processing stations, making the overall structure more compact and the operation more continuous, thereby improving production efficiency.

[0042] Furthermore, such as Figures 5 to 8 As shown, the switching device 300 includes a material loading mechanism 310, a support frame 320, a turntable 330, and a first motor 340. The support frame 320 is rotatably mounted on the support plate of the frame via the turntable 330 and is driven to rotate by the first motor 340. The four walls of the support frame 320 are provided with sliding grooves 321, and the material loading mechanism 310 is slidably disposed in the sliding grooves 321 and supported by multiple first springs 350. The material loading mechanism is maintained at a preset height by the multiple first springs when not subjected to external force. This structural design allows the material loading mechanism to have the basic conditions for vertical movement. When it moves to the position of the solder supply device, the pushing structure presses down on the material loading mechanism to make the solder joint of the workpiece contact the solder, thereby completing the required soldering process. On the other hand, it can perform corresponding processing at four workstations simultaneously, realizing the overall continuous operation and improving the overall efficiency.

[0043] Furthermore, such as Figure 8 , Figure 10As shown, the frame 311 of the material loading mechanism 310 is provided with multiple first guide rods 312; the support frame 320 includes a circular cover 322, a square cover 323 is fixedly provided on the top surface of the circular cover 322, and upwardly extending support rods 324 are fixedly provided at the four corners of the square cover 323. The slide groove 321 is formed between two support rods 324 on the same wall surface, and the material loading mechanism 310 is slidably engaged in the slide groove 321; the top surface of the square cover 323 is provided with multiple first guide holes 325 corresponding to the first guide rods of the multiple material loading mechanisms, and the first guide rods 312 pass through the first guide holes 325, and the bottom of the first guide rods... The end is equipped with a first retaining ring for preventing detachment; each first guide rod 312 is fitted with a first spring 350 for supporting the material loading mechanism; this design can further limit the connection and cooperation between the material loading mechanism and the support frame. Through the cooperation of multiple first guide rods and first guide holes and the cooperation of the frame and the slide, the material loading mechanism can only move in the vertical direction, so that the subsequent material loading mechanism can accurately rotate and swing to the corresponding processing position; and by using the first guide rod as the installation position of the first spring, it can not only meet the elastic support of the frame, but also effectively prevent the first spring from deviating and maintain an effective support effect.

[0044] Furthermore, such as Figure 5 , Figure 10 and Figure 12 As shown, the switching device 300 includes a support frame 360; the support frame 360 ​​includes a support rod 361, a bracket 362 is fixedly provided at the bottom end of the support rod 361, and a support plate 363 is fixedly installed at the top end. The bracket 362 is fixedly installed on the support plate by bolts. The top end of the support rod extends through the top surface of the square cover. The support plate 363 is located above the top surface of the square cover 323. The support plate 363 has a notch 364 on the side near the solder supply device. The frame 311 has a protruding plate 313 fixedly provided at the top of the side near the center of the square cover. The size of the protruding plate is smaller than the size of the notch. When the material loading mechanism rotates to the soldering station, the position of the protruding plate corresponds to the position of the notch. The protruding plate moves down with the material loading mechanism and passes through the notch. A bullseye bearing 370 is installed on the bottom surface of the protruding plate 313. The bottom end of the ball of the bullseye bearing 370 is flush with the top surface of the support plate 363. The edge of the notch is chamfered to reduce the thickness of the edge of the notch.

[0045] Except for the soldering station where the material carrier mechanism needs to move the solder downwards, the other processing steps do not require the material carrier mechanism to move downwards. However, due to the repeated expansion and contraction of the first spring during operation, deformation fatigue or deviation may occur, thus affecting the processing actions of other stations. Therefore, by adding a support plate, the frame of the material carrier mechanism at other processing stations is supported, so that these material carrier mechanisms are maintained in the required position and height, ensuring the accuracy of workpiece transfer or processing. In addition, bullseye bearings are installed on the convex plate, which can reduce the contact area with the support plate and maintain effective rotational sliding fit.

[0046] If the elastic support weakens, it means that the material-carrying mechanism will drop a certain distance. The notch edge is chamfered to form a thinner section so that the balls of the bullseye bearing can slide smoothly, thereby moving the entire material-carrying mechanism to the required height.

[0047] Furthermore, a first circular hole is provided in the center of the top surface of the square cover, and the inner wall of the first circular hole is provided with teeth distributed in a circle; the first motor is fixedly mounted on the support rod by bolts, and the output shaft of the first motor is fixedly mounted with a first gear, which meshes with the teeth at the first circular hole to drive the support frame to rotate; a conductive slip ring is installed on the support rod to provide power to the material loading mechanism.

[0048] Furthermore, such as Figures 9 to 11 As shown, the material loading mechanism 310 includes a frame 311, a second motor 314, and rollers 315. A protruding frame plate 316 is fixedly provided on the top side of the frame 311 near the center of the switching device, and a protruding plate 313 is provided on the middle part of the side of the frame plate 316 away from the frame. A first guide rod 312 is fixedly provided on the bottom surface of the frame plate 316. The rollers 315 are cut to form a flat loading surface 317, and a magnetic strip is fixedly embedded inside the rollers. The magnetic strip is set close to the loading surface for magnetically attracting the workpiece. Arms 318 are installed on the outer sides of both ends of the frame 311. The arms are inclined downwards away from the protruding plate. The rollers 315 are rotated between the bottom ends of the two arms 318 through bearings and are driven to rotate by the second motor 314 to adjust the orientation of the loading surface. The above structural design allows the first motor to drive the rollers to rotate, thereby adjusting the orientation of the loading surface. For example, at the loading station, the loading surface needs to face upwards; at the flux application station and soldering station, the loading surface needs to face downwards; at the unloading station, the loading surface needs to face away from the switching device to facilitate the collection of the subsequent collection box and the operation of the scraping structure. More specifically, it also includes a drive shaft, with a groove on the outer wall of the connection end between the boom and the frame for bearings; the drive shaft passes through both ends of the frame, with the outer end installed at the bearing; a third gear is located in the middle of the drive shaft; the output shaft of the second motor is fixedly equipped with a second gear, and the second gear meshes with the third gear for transmission; the end of the drive shaft is connected to the end of the roller on the same side via a synchronous belt pulley assembly.

[0049] The material discharge device includes a second linear slide, a pushing structure, and a conveying structure. The second linear slide has a platform mounted on its slider, and the platform has multiple spaced slots. The pushing structure has a fourth cylinder and a material channel for closely arranging workpieces. One end of the material channel is connected to an external vibrating feeder, which enables continuous feeding. The fourth cylinder pushes the workpieces at the end of the material channel to the slots on the platform. The conveying structure includes a fifth cylinder, a sixth cylinder, and a suction cup. The fifth cylinder is mounted on a support plate via a bracket and is vertically oriented. A support frame is connected to the piston rod end of the fifth cylinder. The sixth cylinder is mounted on the top surface of the support frame, with the piston rod end of the sixth cylinder facing the reversing device. The suction cup is mounted on the piston rod end of the sixth cylinder and is connected to an external negative pressure device via a hose. The fifth and sixth cylinders drive the suction cup to move, transferring the workpieces on the platform to the corresponding rollers, thus achieving material discharge and feeding.

[0050] The flux supply device includes a seventh cylinder, a first water tank, and a second water tank. The first water tank is mounted on a support plate via a bracket, and the seventh cylinder is mounted on the support plate via a bracket. The second water tank is located inside the first water tank and is filled with a sponge block. The bottom of the second water tank has a through hole. The second water tank is connected to the piston rod end of the seventh cylinder via a pusher. The seventh cylinder drives the second water tank to move up and down. When it moves down, it can be immersed in the flux in the first water tank. When it moves up, it can bring the sponge block with flux adsorbed into contact with the workpiece to achieve flux application.

[0051] Furthermore, such as Figure 3 , Figure 4 As shown, the pushing structure 140 includes a first cylinder and a first push plate installed at the end of the piston rod of the first cylinder; the position of the first push plate corresponds to the connection between the protrusion plate and the frame. Its structure is simple. The first cylinder drives the first push plate to move down, which can realize the downward pressing and pushing of the frame, so that it moves to the required height position and realizes the soldering action.

[0052] Furthermore, such as Figure 3 , Figure 4 As shown, the scraping structure 150 includes a second cylinder and a second push plate installed at the end of the piston rod of the second cylinder. A scraper is vertically fixed on the bottom surface of the second push plate. When the roller rotates to the vertically placed position of the workpiece surface, the workpiece surface is flush with the wall of the scraper. The second cylinder drives the scraper to move down to a preset position, so that the workpiece is removed from the roller and falls into the collection box. Its structure is simple. The scraper pushes the workpiece by the second cylinder, so that the workpiece is removed from the magnetic attraction part and falls into the collection box, thus completing the overall soldering operation.

[0053] Furthermore, such as Figure 7 , Figure 8As shown, the device includes a limiting structure 380, which is located below the material-carrying mechanism corresponding to the molten solder supply device. The limiting structure 380 includes a third cylinder 381 and a third push plate 382 installed at the end of the piston rod of the third cylinder. A vertically extending limiting plate 383 is fixedly provided on the top surface of the third push plate 382. A first through hole is provided on a support plate located inside the dome. The third cylinder is located below the first through hole and is mounted on the support plate via a bracket. The third push plate is located above the first through hole and inside the dome. The top surface of the dome 322 has multiple second through holes 326 corresponding to multiple material-carrying mechanisms. The positions of the second through holes 326 are related to the limiting plate 383. With corresponding positions and suitable shapes, the third cylinder drives the limiting plate to extend out of the outer part of the circular cover through the second perforation, which is used to limit and support the bottom of the upper frame. As mentioned above, the first spring may experience fatigue or deviation during its back-and-forth expansion and contraction, resulting in changes in its elastic support force, which may affect the operation of the push structure that works with it to a certain extent. The added limiting structure limits the extreme position of the frame's downward movement through the limiting plate, which can support the frame. On the one hand, it can disperse and reduce the concentrated force during the compression process of the first spring to a certain extent. On the other hand, it can further limit the downward movement distance, so that the workpiece can accurately pick up the required amount of molten solder and improve product quality.

[0054] Furthermore, such as Figures 13 to 15 As shown, the molten tin supply device 200 includes a slag-removing mechanism 400 mounted on a support plate, a guide structure 220, a material trough 230, and a tin bath 210 with heating function; the tin bath 210 is located below the roller 315, and the material trough 230 is located on the side of the tin bath 210 away from the switching device 300, with the top of the material trough lower than the top of the tin bath; the guide structures 220 are arranged in pairs on the outer sides of both ends of the tin bath 210; the slag-removing mechanism 400 includes a first linear slide 410 and a slag-removing structure 420, the slag-removing structure consisting of a first linear slide 410 and a slag-removing structure 420. A linear slide moves along a guide structure, scraping the slag on the surface of the molten solder into the slurry tank. Slag removal is an essential molten solder treatment process in immersion soldering, preventing surface slag from affecting solder quality. Multiple laser rangefinders are installed above the molten solder tank to monitor the molten solder level at multiple points. A solder replenishment machine is also installed on one side of the molten solder tank to replenish the molten solder by feeding solder bars into the tank. The laser rangefinders and solder replenishment machine are existing equipment and instruments that can be purchased and used on the market; their specific structures will not be described in detail.

[0055] Furthermore, the slag removal structure 420 includes a first plate 421 and a second plate 422. One side of the first plate and one side of the second plate are rotatably connected by a rotating shaft. The other side of the first plate 421 is bolted to the slider of the first linear slide 410. The other side of the second plate extends to both ends, with a length greater than the length of the roller and less than the length of the tin bath. The guide structure 220 includes a vertical plate 221. A flange is fixedly provided on the bottom of the side wall of the vertical plate, and the flange is fixed to the support plate by bolts. A guide groove 222 is provided on the wall of the vertical plate 221 near the tin bath, and a limiting device is fixedly provided inside the guide groove 222. Block 223 has a gap between its sidewall and the guide groove wall. The limiting block has a triangular structure, with its top surface being a slope that tilts upwards towards the switching device. The limiting block 223 divides the interior of the guide groove 222 into a first slide 224, a second slide 225, a third slide 226, and a fourth slide 227. The first slide is located below the limiting block, and the second slide is located above the limiting block. The top of the second slide is connected to the end of the first slide via the third slide, and the bottom of the second slide is connected to the other end of the first slide via the fourth slide. The fourth slide 227 is located close to the limiting block. The end of the plate is equipped with a spring piece 228, which is bent to form a supporting inclined surface that pushes towards the second slide. A scraper 423 is fixedly provided on the bottom surface of the second plate 422 away from the first plate, and a support rod 424 extending to both ends is fixedly provided on this side. The ends of the support rod 424 are slidably mounted in the guide groove 222. When the first linear slide moves the slag removal structure away from the switching device, the support rod moves along the first slide, and the scraper extends into the tin bath to scrape and push the surface slag. When the support rod moves to the position of the spring piece, under the guidance of the spring piece, the support rod moves to the second slide, and the first linear slide moves back simultaneously. The frame moves upward along the second slide, and the scraper detaches from the molten solder. When the frame moves to the position of the third slide, the first linear slide stops moving, and the second plate swings downward along the third slide via the frame, while the scraper moves back to the slag removal depth. The slag removal action requires coordination with lateral and lifting movements. Traditional drive structures use two drive components to achieve the required actions. However, the above structure guides and limits the movement of the second plate, allowing it to complete the slag removal action under the drive of the first linear slide. The structure is simple, reduces equipment costs and subsequent maintenance or replacement costs, and is convenient for practical applications.
