Description

Technical Field

[0001] This invention belongs to the field of capacitor manufacturing technology, specifically a feeding line for the production of aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitors are made by inserting a bent aluminum strip as the positive electrode into an aluminum cylinder containing liquid electrolyte as the negative electrode. They also require DC voltage treatment to form an oxide film on the positive electrode as the dielectric. Their characteristics include large capacitance, but also high leakage current, poor stability, and polarity. They are suitable for power supply filtering or low-frequency circuits. Feeding devices are often required during the assembly and production of aluminum electrolytic capacitors.

[0003] The existing feeding device is unable to process a pile of capacitors of the same specifications in a disorderly manner, thus having certain limitations.

[0004] Therefore, our R&D personnel have proposed a patent with publication number CN210635240U, entitled "A Feeding Device for the Production of Aluminum Electrolytic Capacitors," to address the above-mentioned problems. The device uses a rotary motor to drive a rotating wheel, which, in conjunction with a connecting rod, a T-shaped transmission rod, and a spring, causes a vibrating feeding cylinder to vibrate back and forth in the horizontal direction. This allows the capacitors to fall sequentially into the limiting feeding tube, ensuring that the capacitors in the limiting feeding tube fall accurately into the placement slot, thus providing a neat and orderly feeding process and solving the aforementioned problems.

[0005] However, during subsequent use, we found that after the capacitors were introduced into the placement chamber using the feeding tube, the position of the capacitors could not be adjusted, and the orientation of the capacitors could not be guaranteed to be uniform. When assembling the capacitors, it was still necessary to adjust the position of the capacitors before assembly could proceed. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention designs a feeding line for the production of aluminum electrolytic capacitors, including a feeding bin for placing capacitors to be assembled; the capacitor includes a capacitor core and leads; and a support is installed at the bottom of the feeding bin.

[0007] The inside of the feeding hopper has two inclined platforms fixed on the left side, with a distance between the two inclined platforms; the inside of the feeding hopper has an upwardly sloping arc surface on the right side.

[0008] A drive mechanism is provided between the two inclined platforms; adjustment mechanisms are installed on both sides of the drive mechanism on the inclined platforms; the drive mechanism includes two drive shafts;

[0009] One of the drive shafts passes through the tops of the two ramps and is driven by a motor; the other drive shaft passes through the two supports; a roller is fixedly connected to both drive shafts; a conveyor belt is rotatably connected to both rollers.

[0010] The conveyor belt is located between two inclined platforms and extends partially below the feeding hopper and passes through the feeding hopper; the conveyor belt has evenly arranged semi-circular grooves, which are used to transport capacitors.

[0011] The adjustment mechanism includes a first limiting plate and a second limiting plate, and the first limiting plate and the second limiting plate are respectively installed on two inclined platforms and located on both sides of the conveyor belt.

[0012] The first limiting plate and the second limiting plate bend towards opposite sides on the side near the bottom of the inclined platform; the first limiting plate and the second limiting plate are in contact with the inclined platform that is close to them; the height of the first limiting plate and the second limiting plate is lower than the lowest point of the upper lead of the capacitor.

[0013] An upwardly extending arc-shaped guide plate is fixedly connected to the upper surface of the second limiting plate at the middle position of the second limiting plate; a material blocking plate is provided on the upper left side of the arc-shaped guide plate between two inclined platforms; mounting plates are fixedly connected to the two end faces of the material blocking plate; connecting rods are installed on the two mounting plates, and the other side of the connecting rods is fixedly connected to the inclined platform; a pusher plate is installed on the side of the material blocking plate facing the arc-shaped guide plate.

[0014] Preferably, an auxiliary component is provided between each pair of adjacent semicircular grooves; the auxiliary component includes a sliding groove; the sliding groove is formed between two adjacent semicircular grooves;

[0015] Each of the aforementioned chutes has a sliding support plate, and the top and bottom sections of the support plate are semi-circular; the top and bottom of the support plate partially extend out of the conveyor belt; the elongated chute formed by the conveyor belt is provided with a guide block, and the top of the guide block protrudes upward; the guide block is fixedly connected to the inclined platform.

[0016] Two mounting blocks are fixedly connected to the side of the support plate facing the guide block, and springs are fixedly connected to the mounting blocks. The other end of the springs is fixedly connected to the conveyor belt. Annular grooves are formed on the two rollers, and the width of the annular grooves is the same as the width of the support plate.

[0017] Each of the support plates has an arc-shaped groove on one side near the two semi-circular grooves; an arc-shaped plate is rotatably connected to each arc-shaped groove by a torsion spring;

[0018] In the initial state, part of the arc-shaped groove is located inside the slide groove, and the arc-shaped groove on the support plate located at the top protrusion of the guide block is located above the slide groove.

[0019] The top of the support plate is a smooth surface.

[0020] Preferably, the maximum distance between the first limiting plate and the second limiting plate bending to opposite sides is less than the sum of the lengths of the two capacitor cores;

[0021] The first limiting plate and the second limiting plate are rotatably connected on opposite end faces with evenly arranged rollers.

[0022] Preferably, threaded rods are rotatably connected to the opposite sides of the first limiting plate and the second limiting plate; a rectangular block is fixedly connected to the opposite sides of the two threaded rods on the inclined platform, and a threaded groove is opened in the rectangular block, and the threaded rods mesh with the threaded grooves;

[0023] The mounting plate is slidably connected to the connecting rod; the connecting rod is threaded; a nut is threadedly engaged with the connecting rod below the mounting plate.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The feeding line for producing aluminum electrolytic capacitors according to the present invention, by setting a first limiting plate and a second limiting plate, can push the capacitor into the semi-circular groove and make it fit against the semi-circular groove, thereby ensuring that the capacitor is completely located in the semi-circular groove. By setting an arc-shaped guide plate, the capacitor with the lead wire facing the second limiting plate can be lifted out of the semi-circular groove and then slid into the feeding bin. By setting a pusher plate, the capacitor pressed against the semi-circular groove can be pushed away, thereby ensuring that only the capacitor with the lead wire facing the first limiting plate can move upward. This ensures that the capacitor moves in a uniform direction, and there is no need to readjust the position of the capacitor during subsequent assembly, thereby saving operation steps and improving assembly efficiency.

[0026] 2. The feeding line for producing aluminum electrolytic capacitors according to the present invention allows capacitors to slide down along the top of the capacitors in the semi-circular groove and the top of the support plate when they slide off the conveyor belt. Due to the presence of the support plate, which is located between capacitors in two adjacent semi-circular grooves, the sliding capacitors are prevented from hitting the capacitors in the adjacent semi-circular grooves, thus avoiding affecting the sliding process. At the same time, the capacitors in the semi-circular grooves are clamped and fixed by the arc plate, preventing them from hitting the capacitors in the semi-circular grooves when they slide off, thus preventing the capacitors in the semi-circular grooves from popping out of the semi-circular grooves.

[0027] 3. In the aluminum electrolytic capacitor production feeding line of the present invention, since the maximum distance between the first limiting plate and the second limiting plate bending to opposite sides is less than the sum of the lengths of the two capacitor cores, when the two capacitors fall into the same semicircular groove and move with the semicircular groove to the position of the first limiting plate and the second limiting plate, one or two capacitors in the semicircular groove will contact the first limiting plate or the second limiting plate, thereby pushing one or two capacitors in the semicircular groove down from the semicircular groove. This avoids the two capacitors in the first semicircular groove from getting stuck between the first limiting plate and the second limiting plate when they move upwards, thus affecting the feeding process of the conveyor belt.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] like Figures 1 to 9 As shown, the present invention provides a feeding line for the production of aluminum electrolytic capacitors; it includes a feeding bin 1, which is used to place capacitors 11 to be assembled; the capacitor 11 includes a capacitor core and leads 12; a support 13 is installed at the bottom of the feeding bin 1.

[0042] The inside of the feeding bin 1 has two inclined platforms 14 fixedly connected to the left side, with a distance between the two inclined platforms 14; the inside of the feeding bin 1 has an upwardly sloping arc surface on the right side.

[0043] A drive mechanism is provided between the two inclined platforms 14; adjustment mechanisms are installed on both sides of the drive mechanism on the inclined platforms 14; the drive mechanism includes two drive shafts 2.

[0044] One of the drive shafts 2 passes through the top of the two inclined planes 14 and is driven by a motor 21; the other drive shaft 2 passes through the two supports 13; a roller 22 is fixedly connected to both drive shafts 2; a conveyor belt 3 is rotatably connected to both rollers 22.

[0045] The conveyor belt 3 is located between two inclined platforms 14 and extends partially below the feeding bin 1 and passes through the feeding bin 1; the conveyor belt 3 is provided with evenly arranged semi-circular grooves 31, and the semi-circular grooves 31 are used to transport capacitors 11.

[0046] The adjustment mechanism includes a first limiting plate 4 and a second limiting plate 41, and the first limiting plate 4 and the second limiting plate 41 are respectively installed on two inclined platforms 14 and located on both sides of the conveyor belt 3.

[0047] The first limiting plate 4 and the second limiting plate 41 are bent to opposite sides on the side near the bottom of the inclined platform 14; the first limiting plate 4 and the second limiting plate 41 are in contact with the inclined platform 14 that are close to each other; the height of the first limiting plate 4 and the second limiting plate 41 is lower than the lowest point of the upper lead 12 of the capacitor 11.

[0048] An upwardly extending arc-shaped guide plate 42 is fixedly connected to the upper surface of the second limiting plate 41 at the middle position of the second limiting plate 41; a material blocking plate 5 is provided on the upper left of the arc-shaped guide plate 42 between the two inclined platforms 14; mounting plates 51 are fixedly connected to the two end faces of the material blocking plate 5; connecting rods 52 are installed on the two mounting plates 51, and the other side of the connecting rods 52 is fixedly connected to the inclined platform 14; a pusher plate 53 is installed on the side of the material blocking plate 5 facing the arc-shaped guide plate 42;

[0049] During operation, the capacitor 11 to be assembled is first transferred to the feeding bin 1, and the motor 21 is controlled to rotate. The motor 21 drives the drive shaft 2 to rotate, and the drive shaft 2 drives the conveyor belt 3 to rotate cyclically towards the top of the inclined platform 14 through the rotating roller 22. When the conveyor belt 3 rotates, the capacitor 11 in the feeding bin 1 will contact the rotating conveyor belt 3, and some of the capacitors 11 will fall into the semi-circular groove 31. The position and orientation of the capacitors 11 that fall into the semi-circular groove 31 are uncertain. The capacitors 11 in the semi-circular groove 31 may have their leads 12 facing the first limiting plate 4 or the second limiting plate 41, or the capacitors 11 in the semi-circular groove 31 may be pressed against the semi-circular groove 31 and perpendicular to the semi-circular groove 31. The capacitors 11 that are attached to the semi-circular groove 31 may also have their positions shifted. When the capacitor 11 falls into the semi-circular groove 31 and becomes stable, the semi-circular groove 31 will drive the stable capacitor 11 to move upward.

[0050] During the movement of capacitor 11 driven by semicircular groove 31, the moving capacitor 11 will gradually approach the first limiting plate 4 and the second limiting plate 41. When the offset capacitor 11 in semicircular groove 31 comes into contact with the first limiting plate 4 or the second limiting plate 41, under the guidance of the first limiting plate 4 and the second limiting plate 41, it will push the capacitor 11 to slide into semicircular groove 31. When semicircular groove 31 moves capacitor 11 to the straight position of the first limiting plate 4 and the second limiting plate 41, the offset capacitor 11 in semicircular groove 31 will be completely attached to semicircular groove 31 and located in semicircular groove 31. Since the height of the first limiting plate 4 and the second limiting plate 41 is lower than the lowest point of the lead 12 on capacitor 11, the lead 12 on capacitor 11 moving with semicircular groove 31 will not come into contact with the first limiting plate 4 and the second limiting plate 41.

[0051] As the capacitor 11, which is fully in contact with the semicircular groove 31, continues to move upward, the lead wire 12 on the capacitor 11, which is facing the second limiting plate 41, will gradually come into contact with the arc-shaped guide plate 42 because the top of the second limiting plate 41 is fixedly connected to the arc-shaped guide plate 42. As the semicircular groove 31 continues to drive the lead wire 12 to move towards the capacitor 11 towards the second limiting plate 41, the lead wire 12 will be gradually lifted under the guidance of the arc-shaped guide plate 42, thereby lifting the capacitor 11 itself. The lifted capacitor 11 will slide down the conveyor belt 3 into the feeding bin 1. At the same time, the capacitor 11 with the lead wire 12 facing the first limiting plate 4 will continue to move upward with the semicircular groove 31. When the capacitor 11 with the lead wire 12 facing the first limiting plate 4 moves to the top position of the conveyor belt 3, the capacitor 11 will roll into the material channel and then enter the assembly machine of the capacitor 11 for assembly.

[0052] When the capacitor 11, which is pressed against the semi-circular groove 31 and perpendicular to the semi-circular groove 31, moves upward with the semi-circular groove 31, it will gradually come into contact with the pusher plate 53. When the capacitor 11 pressed against the semi-circular groove 31 comes into contact with the pusher plate 53, the pusher plate 53 will push the capacitor 11 to roll downward, so that only the capacitor 11 with the lead wire 12 moving upward toward the first limiting plate 4 can be moved upward, thereby achieving the screening of the capacitor 11.

[0053] In summary, by setting the first limiting plate 4 and the second limiting plate 41, the capacitor 11 can be pushed into the semi-circular groove 31 and fit against it, thus ensuring that the capacitor 11 is completely located within the semi-circular groove 31. By setting the arc-shaped guide plate 42, the capacitor 11 with the lead wire 12 facing the second limiting plate 41 can be lifted out of the semi-circular groove 31, and then the capacitor 11 can slide into the feeding bin 1. By setting the pusher plate 53, the capacitor 11 that is pressed against the semi-circular groove 31 can be pushed away, thus ensuring that only the capacitor 11 with the lead wire 12 facing the first limiting plate 4 can move upward. This ensures that the capacitor 11 moves in a uniform direction, and there is no need to readjust the position of the capacitor 11 during subsequent assembly, thereby saving operation steps and improving assembly efficiency.

[0054] In one embodiment of the present invention, an auxiliary component is provided between two adjacent semicircular grooves 31; the auxiliary component includes a sliding groove 32; the sliding groove 32 is formed between two adjacent semicircular grooves 31.

[0055] Each of the grooves 32 has a support plate 33 that slides within it, and the top and bottom sections of the support plate 33 are both semi-circular; the top and bottom of the support plate 33 partially extend out of the conveyor belt 3; the elongated groove formed by the conveyor belt 3 is provided with a guide block 34, and the top of the guide block 34 protrudes upward; the guide block 34 is fixedly connected to the inclined platform 14.

[0056] Two mounting blocks 35 are fixedly connected to the side of the support plate 33 facing the guide block 34, and a spring is fixedly connected to the mounting block 35. The other end of the spring is fixedly connected to the conveyor belt 3. Annular grooves 23 are opened on the two rotating rollers 22, and the width of the annular grooves 23 is the same as the width of the support plate 33.

[0057] Each of the support plates 33 has an arc-shaped groove 36 on one side near the two semi-circular grooves 31; an arc plate 37 is rotatably connected to each arc-shaped groove 36 by a torsion spring.

[0058] In the initial state, part of the arc-shaped groove 36 is located inside the slide groove 32, and the arc-shaped groove 36 on the support plate 33 located at the top protrusion of the guide block 34 is located above the slide groove 32.

[0059] The top of the support plate 33 is a smooth surface;

[0060] During operation, as the conveyor belt 3 rotates in a cycle, it will drive the support plate 33 in the chute 32 to rotate in a cycle. The support plate 33 will rotate around the annular groove 23 on the roller 22 and the contour surface of the guide block 34. When the chute 32 drives the support plate 33 to rotate to the position of the top protrusion of the guide block 34, the protrusion on the guide block 34 will push the support plate 33 to extend out of the conveyor belt 3, and make the arc groove 36 protrude from the chute 32. After the arc groove 36 is exposed from the chute 32, the arc plate 37 rotates under the action of the torsion spring. After the rotation, the arc plate 37 will fit against the surface of the adjacent capacitor 11, and the capacitor 11 can be clamped and fixed at this time.

[0061] When a capacitor 11 slides off the conveyor belt 3, the capacitor 11 can slide down along the top of the capacitor 11 in the semi-circular groove 31 and the top of the support plate 33. Due to the presence of the support plate 33, and the fact that the support plate 33 is located between the capacitors 11 in two adjacent semi-circular grooves 31, the sliding capacitor 11 can be prevented from hitting the capacitors 11 in the two adjacent semi-circular grooves 31, thus affecting the sliding process of the capacitor 11. At the same time, since the capacitor 11 in the semi-circular groove 31 is clamped and fixed by the arc plate 37, it is prevented from hitting the capacitors 11 in the semi-circular groove 31 when sliding down, thus preventing the capacitors 11 in the semi-circular groove 31 from popping out of the semi-circular groove 31.

[0062] After the support plate 33 slides down from the top of the guide block 34, the spring on the mounting block 35 will push the support plate 33 back to its initial state, and at the same time drive the arc groove 36 part to slide into the slide groove 32. Meanwhile, the arc plate 37 will rotate back into the arc groove 36 under the limit of the slide groove 32.

[0063] As one embodiment of the present invention, the maximum distance between the first limiting plate 4 and the second limiting plate 41 bending to opposite sides is less than the sum of the lengths of the two capacitor cores 11.

[0064] The first limiting plate 4 and the second limiting plate 41 are rotatably connected to the opposite end faces of the rollers that are evenly arranged.

[0065] During operation, since the maximum distance between the first limiting plate 4 and the second limiting plate 41 bending to opposite sides is less than the sum of the lengths of the two capacitor cores 11, when the two capacitors 11 fall into the same semicircular groove 31 and move with the semicircular groove 31 to the positions of the first limiting plate 4 and the second limiting plate 41, one or two capacitors 11 in the semicircular groove 31 will contact the first limiting plate 4 or the second limiting plate 41. This will push one or two capacitors 11 out of the semicircular groove 31, thus preventing the two capacitors 11 from getting stuck between the first limiting plate 4 and the second limiting plate 41 when they move upwards in the first semicircular groove 31, thereby affecting the feeding process of the conveyor belt 3.

[0066] Since the first limiting plate 4 and the second limiting plate 41 are rotatably connected to the opposite end faces of the rollers, when the capacitor 11 moves along the first limiting plate 4 or the second limiting plate 41, the presence of the rollers can reduce the friction between the capacitor 11 and the first limiting plate 4 or the second limiting plate 41.

[0067] In one embodiment of the present invention, threaded rods 43 are rotatably connected to the opposite sides of the first limiting plate 4 and the second limiting plate 41; a rectangular block 44 is fixedly connected to the opposite sides of the two threaded rods 43 on the inclined platform 14, and a threaded groove is opened in the rectangular block 44, and the threaded rods 43 mesh with the threaded groove.

[0068] The mounting plate 51 is slidably connected to the connecting rod 52; the connecting rod 52 is threaded; a nut 54 is threadedly engaged with the connecting rod 52 below the mounting plate 51.

[0069] During operation, when feeding different types of capacitors 11, the conveyor belt 3 can be replaced according to the type of capacitor 11, so that the diameter of the semi-circular groove 31 on the replaced conveyor belt 3 is the same as the diameter of the capacitor 11. Then, the threaded rod 43 is rotated so that the threaded rod 43 drives the first limiting plate 4 and the second limiting plate 41 to move closer or further apart. Finally, the distance between the direct positions of the first limiting plate 4 and the second limiting plate 41 is adjusted to be the same as the length of the capacitor 11. Then, the mounting plate 51 is pushed up or down on the connecting rod 52. After the position of the mounting plate 51 is adjusted, the nut 54 is rotated to support the mounting plate 51 from below.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
