Description

Technical Field

[0001] The utility model relates to the field of blanking machines, in particular to an automatic tin dipping and blanking mechanism. Background Art

[0002] Capacitors are mainly used for energy storage, filtering, coupling, and voltage regulation in circuits. These functions make capacitors play a crucial role in electronic devices. Capacitor sleeves are widely used in electronic devices and circuit designs. Some of their applications include: 1. Power supply voltage filter: used to eliminate noise in the power supply; 2. Choke filter: used in conjunction with inductors to filter high-frequency waveforms and noise; 3. Signal coupling capacitor: used to increase the gain of an amplifier; 4. Signal conditioner: provides stable capacitor performance for signal processing circuits. The capacitors in capacitor sleeves are one of the essential basic components in electronic devices and circuit designs. They can help the circuit maintain stability, improve circuit performance, and thus achieve different circuit functions.

[0003] After the capacitor is sleeved, it is necessary to dip the pins of the capacitor in tin. Traditionally, the capacitor pins are manually held and placed into the tin furnace for tin dipping processing. The manual method of dipping the capacitor pins in tin easily causes the pins to have uneven tin dipping lengths, resulting in unqualified tin dipping of the capacitor pins. Therefore, the manual operation method of dipping the capacitor pins in tin not only has the disadvantages of low tin dipping efficiency, poor tin dipping effect, low tin dipping accuracy, and low product yield rate, but also leads to high labor intensity of workers and high labor costs for enterprises, which is not conducive to the requirements of large-scale batch production and high-quality production of enterprises. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic tin dipping and blanking mechanism.

A first mounting plate is arranged on the lifting plate. One side surface of the first mounting plate is connected and installed with the lifting plate. The other three side surfaces of the first mounting plate are respectively provided with a second mounting plate, a third mounting plate, and a fourth mounting plate. A first cylinder is arranged on the second mounting plate. A second cylinder is arranged on the third mounting plate. A third cylinder is arranged on the fourth mounting plate. A pulley assembly is arranged on the first mounting plate. A rotating frame is arranged below the first mounting plate. Clamping devices are respectively arranged on the four side surfaces of the rotating frame. A positioning fixture, a capacitor top plate, a tin supply assembly, and a material tank are respectively arranged below the rotating frame. A Geneva wheel assembly is arranged on the other side of the vertical plate. A spline sleeve spline shaft assembly is arranged on the Geneva wheel assembly. The Geneva wheel assembly is drivingly connected with the pulley assembly through the spline sleeve spline shaft assembly.

[0006] By adopting the above technical solution, the Geneva wheel assembly drives the clamping device on the rotating frame to rotate through the spline sleeve spline shaft assembly and the pulley assembly for station transformation. The tin dipping lifting drive assembly drives the pulley assembly, the rotating frame and the clamping device thereon to lower. The lowered clamping device can pick up the inductor on the positioning fixture. Then, the finger device conveys the capacitor pins to the capacitor top plate and conveys them to a predetermined height to ensure that the tin dipping length of the capacitor pins is consistent. The clamping device clamps the capacitor to dip the capacitor pins on the tin supply assembly. After the capacitor pins are dipped in tin, the clamping device releases the dipped capacitor on the chute for finished product blanking and recycling. Then, the tin dipping lifting drive assembly drives the pulley assembly, the rotating frame and the clamping device on the rotating frame to rise and reset together. The Geneva wheel assembly drives the rotating frame to rotate the clamping device thereon by 90 degrees and then prepares to dip the next capacitor.

[0007] Preferably, the pulley assembly includes a fifth mounting plate installed on the first mounting plate. A spline shaft and a rotating frame rotating shaft are respectively arranged at both ends of the fifth mounting plate. A driving pulley is arranged at the upper end of the spline shaft, and a driven pulley is arranged at the upper end of the rotating frame rotating shaft. The lower end of the rotating frame rotating shaft is fixedly connected to the rotating frame. The driving pulley is drivingly connected to the driven pulley through a belt. A tension pulley is arranged on the fifth mounting plate, and the tension pulley is installed on the fifth mounting plate through a tension pulley positioning plate.

[0008] By adopting the above technical solution, the Geneva wheel assembly drives the driving pulley in the pulley assembly to rotate through the spline sleeve spline shaft assembly. The driving pulley drives the driven pulley to rotate synchronously through the belt. The rotation of the driven pulley can drive the rotation of the rotating frame rotating shaft. The rotation of the rotating frame rotating shaft can drive the rotation of the rotating frame. The rotation of the rotating frame can drive the respective clamping devices installed thereon to rotate and rotate into different stations in turn.

[0009] Preferably, the clamping device includes a clamping slide seat installed on the rotating frame. A clamping slide plate is arranged inside the clamping slide seat. A first guide wheel assembly and a second guide wheel assembly are respectively arranged at both ends of the clamping slide plate.

[0010] By adopting the above technical solutions, since the first cylinder, the second cylinder and the third cylinder are respectively connected and installed with the clamping device located below them, when the first cylinder, the second cylinder and the third cylinder respectively extend downward, they can push the clamping slide plate located below them to approach the direction of the first finger assembly. When the first guide wheel slides obliquely outward from the upper end to the lower end of the first finger and the second guide wheel slides obliquely outward from the upper end to the lower end of the second finger, they can drive the first finger and the second finger to open, preparing for subsequent clamping of the capacitor. Conversely, when the first cylinder, the second cylinder and the third cylinder respectively retract upward to reset, they can pull the clamping slide plate located below them to move away from the first finger assembly, driving the separation of the first guide wheel from the first finger and the second guide wheel from the second finger. The first finger and the second finger are pulled by the tension spring to make a closing movement to automatically clamp or hold the capacitor tightly.

[0011] Preferably, the spline sleeve and spline shaft assembly includes a spline sleeve bearing seat installed on one side of the upper end of the vertical plate. A spline sleeve is provided inside the spline sleeve bearing seat, a spline shaft is provided inside the spline sleeve, and a spline bevel gear is provided at one end of the spline sleeve away from the spline shaft.

[0012] By adopting the above technical solutions, the Geneva wheel assembly drives the spline bevel gear to rotate. The rotating spline bevel gear drives the spline shaft and the spline sleeve to rotate synchronously inside the spline sleeve bearing seat. The spline shaft drives the fifth mounting plate to lift and make telescopic sliding inside the spline sleeve along with the tin dipping lifting drive assembly. While the spline sleeve drives the spline shaft to rotate, the spline shaft makes telescopic sliding inside the spline sleeve. When the tin dipping lifting drive assembly drives the rotating frame to lift, the Geneva wheel assembly drives the rotating frame to rotate to realize the steering switch of the clamping device on the rotating frame between different workstations.

[0014] By adopting the above technical solutions, rotating the dial sprocket in the Geneva wheel assembly can drive the dial to rotate. The dial drives the Geneva wheel to rotate, and then drives the Geneva wheel bevel gear to rotate through the Geneva wheel shaft. The rotating Geneva wheel bevel gear drives the rotating frame and the clamping device thereon to rotate synchronously through the spline sleeve and spline shaft assembly and the pulley assembly for steering switch between different workstations, enabling each clamping device on the rotating frame to rotate to different workstations for processing different processes.

[0015] Preferably, the solder dipping lifting drive assembly includes a linear sliding module installed on the vertical plate. The linear sliding module is connected and installed with the lifting plate. A solder dipping ejector rod is connected below the lifting plate.

[0016] By adopting the above technical solution, when the second solder dipping connecting rod moves upward under the drive of a power source (the power source can be a cylinder connected thereto or other connecting parts that can push it to move), it can drive the rotating frame and the clamping device thereon to reset and rise synchronously through the solder dipping lever, the first solder dipping connecting rod, the solder dipping ejector rod, the lifting plate and the first mounting plate in sequence; conversely, when the second solder dipping connecting rod moves downward under the drive of a power source (the power source can be a cylinder connected thereto or other connecting parts that can push it to move), it can drive the rotating frame and the clamping device thereon to lower synchronously through the solder dipping lever, the first solder dipping connecting rod, the solder dipping ejector rod, the lifting plate and the first mounting plate in sequence.

That is, the solder slag scraper can perform reciprocating movement in the X direction or Y direction and reciprocating movement in the Z direction jointly under the drive of the fourth cylinder and the fifth cylinder, so that the solder slag scraper can automatically scrape the solder slag on the surface of the solder furnace under the joint drive of the fourth cylinder and the fifth cylinder. The scraped solder slag will automatically fall into the solder box for recycling under the influence of its own gravity, realizing automatic removal of the solder slag.

[0019] Preferably, a material groove is provided on one side of the solder furnace. A solder gun support is provided on the material groove. A solder gun for replenishing solder wire to the solder furnace is provided on the solder gun support.

[0020] By adopting the above technical solution, the clamping device moves the capacitor with the pins dipped in solder to the material groove along with the rotation of the rotating frame as it rotates, so that the capacitor slides out along the obliquely arranged material groove to realize automatic recycling of the finished product.

[0021] Preferably, a fixture mounting plate is provided below the positioning fixture.

[0022] It should be noted that the capacitive top plate, spline shaft, tension pulley positioning plate, clamping slide, clamping slide plate, spline sleeve bearing seat, sheave frame, dial sprocket, solder dipping ejector rod, solder dross scraper, solder dipping lever, and fixture mounting plate are respectively functional descriptions of the top plate, connecting shaft, positioning plate, slide, slide plate, bearing seat, frame, sprocket, ejector rod, scraper, lever, and mounting plate.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows: By respectively designing the structures of the sheave assembly, spline sleeve spline shaft assembly, clamping device, and solder dipping lifting drive assembly, and using them in cooperation with the pulley assembly and the rotating frame, the sheave assembly can drive the clamping device on the rotating frame to rotate through the spline sleeve spline shaft assembly and the pulley assembly for station transformation, and the solder dipping lifting drive assembly can drive the pulley assembly, the rotating frame, and the clamping device on the rotating frame to lift. When the clamping device on the rotating frame is lowered under the drive of the solder dipping lifting drive assembly, it can clamp the inductor from the positioning fixture. The finger clamping device conveys the capacitor pins to the capacitive top plate and moves them to a predetermined height through the solder dipping lifting drive assembly to ensure that the solder dipping lengths of the capacitor pins are consistent; when the clamping device clamps the capacitor and completes solder dipping on the solder supply assembly, the clamping device releases the soldered capacitor on the material trough for finished product blanking and recycling. Then, the solder dipping lifting drive assembly drives the pulley assembly, the rotating frame, and the clamping device on the rotating frame to reset and rise, and the sheave assembly drives the rotating frame to rotate, so that another adjacent clamping device on the rotating frame can rotate 90 degrees and rotate to the positioning fixture to clamp the next capacitor to start a new round of solder dipping operation for the next capacitor; by providing clamping devices on multiple sides of the rotating frame, multiple clamping devices can work continuously, which can automatically solder the capacitor pins while ensuring that the lengths of the solder on each capacitor pin are consistent. It has the advantages of high solder dipping efficiency, good tin sticking effect, and high yield rate of finished products for the capacitor pins, and also realizes the reduction of the labor intensity of workers and the labor cost of enterprises.

[0041] In one embodiment, a fixture mounting plate 141 is provided below the positioning fixture 14.

[0042] In one embodiment, the working principle of the automatic solder dipping and blanking mechanism is as follows: When the dial sprocket 185 in the Geneva wheel assembly 18 rotates, it can drive the dial 186 to rotate. Since the dial 186 is drivingly connected to the Geneva wheel 184, the rotation of the dial 186 can drive the Geneva wheel 184 to rotate, and then drive the Geneva wheel shaft 182 to rotate. The rotation of the Geneva wheel shaft 182 can drive the Geneva wheel helical gear 183 mounted on one end thereof to rotate synchronously.

[0043] A spline sleeve spline shaft assembly 19 is provided on the Geneva wheel assembly 18. The spline sleeve spline shaft assembly 19 is meshingly driven with the Geneva wheel helical gear 183 in the Geneva wheel assembly 18 through a spline helical gear 193. When the Geneva wheel helical gear 183 in the Geneva wheel assembly 18 rotates, it can drive the spline helical gear 193 to rotate.

The spline shaft 112 rotates and makes telescopic sliding in the spline sleeve 192 as the solder dipping lifting drive assembly 2 drives the lifting of the fifth mounting plate 111.

[0044] Since the Geneva wheel assembly 18 is drivingly connected to the pulley assembly 11 through the spline sleeve spline shaft assembly 19, when the spline shaft 112 rotates, it can drive the driving pulley 114 in the pulley assembly 11 to rotate. The driving pulley 114 drives the driven pulley 115 to rotate through the belt 116. The driven pulley 115 can drive the rotating frame 12 to rotate through the rotating frame rotating shaft 113, so that each clamping device 13 on the rotating frame 12 can rotate accordingly to realize the steering switch between different workstations.

[0045] When the grooved pulley assembly 18 drives the clamping device 13 on the rotating frame 12 to rotate above the positioning fixture 14 through the spline sleeve spline shaft assembly 19 and the pulley assembly 11, when the second soldering link 26 in the soldering lifting drive assembly 2 is pushed downward, the second soldering link 26 can drive the rotating frame 12 and each clamping device 13 thereon to synchronously lower onto the capacitor placed on the positioning fixture 14 through the soldering lever 24, the first soldering link 23, the soldering ejector rod 22, the lifting plate 3 and the first mounting plate 4 in sequence; when the clamping slide plate 131 in each clamping device 13 approaches the direction of the first finger assembly 134 under the push of the cylinder located above it, when the first guide wheel 1321 slides obliquely outward from the upper end to the lower end of the first finger 1341 and the second guide wheel 1322 slides obliquely outward from the upper end to the lower end of the second finger 1342, it can drive the first finger 1341 and the second finger 1342 to open, preparing for the first finger assembly 134 to clamp the capacitor. Conversely, when the cylinder above the clamping slide plate 131 in each clamping device 13 resets and rises in the direction away from the first finger assembly 134, the first guide wheel 1321 and the second guide wheel 1322 can reset and leave the first finger 1341 and the second finger 1342, and the first finger 1341 and the second finger 1342 are reset and closed under the influence of the tension of the tension spring to automatically clamp or hold the capacitor. Then, the grooved pulley assembly 18 drives the rotating frame 12 and the clamping device 13 with the capacitor clamped thereon to rotate to the capacitor top plate 15 through the spline sleeve spline shaft assembly 19 and the pulley assembly 11, and the rotating frame 12 and the clamping device 13 with the capacitor clamped thereon move with the soldering lifting drive assembly 2 to transfer the capacitor pins to the capacitor top plate 15 and to a predetermined height to ensure that the later soldering length of the capacitor pins is consistent, so that the capacitor pins extend into the tin furnace 161 in the solder supply assembly 16 based on the capacitor top plate 15 for soldering and transfer the capacitor with the capacitor pins soldered to the material chute 17, and the first finger 1341 and the second finger 1342 open according to the aforementioned method to release the clamping of the capacitor, so that the capacitor with the pins soldered slides out through the material chute 17 to complete the finished product blanking and recycling; at this time, pulling up the second soldering link 26 in the soldering lifting drive assembly 2, the second soldering link 26 can drive the rotating frame 12 and the clamping device 13 thereon to synchronously reset and rise through the soldering lever 24, the first soldering link 23, the soldering ejector rod 22, the lifting plate 3 and the first mounting plate 4 in sequence, and the grooved pulley assembly 18 drives the rotating frame 12 and the clamping device 13 on the rotating frame 12 to rotate 90 degrees through the spline sleeve spline shaft assembly 19 and the pulley assembly 11, so that the next adjacent clamping device 13 starts to perform soldering processing on the next capacitor pin.

[0046] Its overall structural design enables the Geneva wheel assembly 18 to drive the clamping device 13 on the rotating frame 12 to rotate for station transformation through the spline sleeve spline shaft assembly 19 and the pulley assembly 11, while the tin dipping lifting drive assembly 2 can drive the pulley assembly 11, the rotating frame 12 and the clamping device 13 on the rotating frame 12 to lift. It can automatically dip the capacitor pins with tin and ensure that the length of each capacitor pin dipped with tin is consistent. It not only has the advantages of high tin dipping efficiency, good tin sticking effect and high yield rate of finished products for capacitor pins, but also reduces the labor intensity of workers and the labor cost of enterprises, effectively solving the problems of low tin dipping efficiency, poor tin dipping effect, low tin dipping accuracy, low yield rate of products, high labor intensity of workers and high labor cost of enterprises caused by the traditional method of manually holding the capacitor and putting the capacitor pins into the tin furnace for tin dipping.
