Description

Technical Field

[0001] The present invention is a belt-type quantitative weighing feeder, belonging to the technical field of transportation. Background Art

[0002] Electrolytic capacitors usually have a metal foil (aluminum / tantalum) as the positive electrode, and an insulating oxide layer of the metal foil (aluminum oxide / tantalum pentoxide) as the dielectric. Electrolytic capacitors are divided into aluminum electrolytic capacitors and tantalum electrolytic capacitors according to their positive electrodes. The negative electrode of an aluminum electrolytic capacitor is composed of thin paper / thin film or electrolyte polymer impregnated with an electrolyte solution (liquid electrolyte); the negative electrode of a tantalum electrolytic capacitor usually uses manganese dioxide.

[0003] Before inserting an electrolytic capacitor into the corresponding circuit board, it is necessary to count the number of electrolytic capacitors, and also to sort and weigh them to prevent the internal electrolyte solution from not being filled. At the same time, for convenient insertion, it is also necessary to cut the pins. The existing operation mode is generally to weigh the weight of one electrolytic capacitor manually, and then weigh the whole package to obtain the total weight of a package. Divide the total weight of a package by each weight to obtain the number of electrolytic capacitors in a package. This method sometimes has a large error. When cutting the pins of electrolytic capacitors, it is also manually cut, which affects the production efficiency and wastes a lot of manpower. Therefore, those skilled in the art have proposed a belt-type quantitative weighing feeder to solve the problems raised in the above background art. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] As Figure 1 and Figure 2 shown, a belt type quantitative weighing feeder includes a feeding structure, a weighing and sorting structure, a transportation structure and a cutting structure; The feeding structure is used to sequentially transport electrolytic capacitors from the storage location to the weighing and sorting structure; The weighing and sorting structure is used to weigh and sort electrolytic capacitors one by one, and transport normal electrolytic capacitors into the transportation structure; The transportation structure is used to automatically transport normal electrolytic capacitors to the finished product storage location; The cutting structure is used to cut the pins of the electrolytic capacitors conveyed in the transportation structure; The feeding structure includes a capacitor bin 1 with upper and lower openings. The electrolytic capacitors to be processed are placed flat in the capacitor bin 1. At the lower material discharging opening of the capacitor bin 1, there is a driving column 2 with grooves evenly distributed on its surface. One end surface of the driving column 2 is fixedly connected with a first gear 4. Diagonally below the driving column 2, there is also an intermediate column 3. The driving column 2 and the intermediate column 3 have the same diameter, and grooves are evenly distributed on the surface of the intermediate column 3. One end surface of the intermediate column 3 is fixedly connected with a second gear 5, and a stepping motor 6 is also fixedly connected to the center of the second gear 5. A chain 7 is connected between the first gear 4 and the second gear 5. Diagonally above the intermediate column 3, there is also an arc cover 12, and one end of the arc cover 12 is fixedly connected to the outer surface of the bin wall of the capacitor bin 1.

[0021] The operator places the electrolytic capacitors to be processed into the capacitor bin 1 in a certain form. The stepping motor 6 is started, driving the second gear 5 and the intermediate column 3 to rotate. Through the action of the chain 7 between the first gear 4 and the second gear 5, the second gear 5 and the driving column 2 rotate, and every once in a while, they rotate by the radian of the adjacent groove of the driving column 2. The electrolytic capacitors at the lower material discharging opening of the capacitor bin 1 fall into the grooves in the driving column 2, then rotate and fall into the grooves in the intermediate column 3.

[0022] The weighing and sorting structure includes a transfer groove 8 with a semi-circular groove opened on its upper surface. The transfer groove 8 is located directly below the intermediate column 3, and weighing columns 9 are fixedly connected to the lower surfaces at both ends of the transfer groove 8, with the lower ends of the weighing columns 9 being hollow.

[0023] Below the transfer groove 8, there are a vertical column 13, a qualified electromagnetic column 11, and a waste electromagnetic column 15. Below the vertical column 13, the qualified electromagnetic column 11, and the waste electromagnetic column 15, there are also weighing sensors 16. After the qualified electromagnetic column 11 and the waste electromagnetic column 15 are electrified, they are filled with magnetism. The vertical column 13 is located directly below the center of the transfer groove 8. There is a weighing rotating shaft 14 between the surface of the center of the vertical column 13 and the transfer groove 8. The upper ends of the qualified electromagnetic column 11 and the waste electromagnetic column 15 are hollow. The qualified electromagnetic column 11 and the waste electromagnetic column 15 are located directly below the weighing column 9. A qualified spring 10 is provided between the qualified electromagnetic column 11 and the weighing column 9, and the qualified spring 10 is located inside the upper end of the qualified electromagnetic column 11 and the hollow lower end of the weighing column 9. A waste spring 32 is provided between the waste electromagnetic column 15 and the weighing column 9, and the waste spring 32 is located inside the upper end of the waste electromagnetic column 15 and the hollow lower end of the weighing column 9.

[0024] The electrolytic capacitor in the groove of the middle column 3 rotates to directly above the transfer groove 8, loses the peripheral restriction of the arc cover 12, and drops into the transfer groove 8. The weighing sensor 16 weighs the electrolytic capacitor. If it is a qualified product, the qualified electromagnetic column 11 is electrified, and the qualified electromagnetic column 11 attracts the weighing column 9 above, causing the transfer groove 8 to tilt around the weighing rotation axis 14 towards the end of the qualified electromagnetic column 11. If it is a defective product, the waste electromagnetic column 15 is electrified, and the waste electromagnetic column 15 attracts the weighing column 9 above, causing the transfer groove 8 to tilt around the weighing rotation axis 14 towards the end of the waste electromagnetic column 15.

[0025] As Figure 1 and Figure 3 shown, the transportation structure includes a belt conveyor 17. Carriers 21 are uniformly fixed on the surface of the belt conveyor 17. Clamping rotation shafts 22 are erected on both sides of the surface of the carriers 21. Clamping arms 24 are fixed on the surface of the clamping rotation shafts 22. The clamping arms 24 are in a corner shape. A torsion spring 23 is provided inside the clamping rotation shafts 22. In the natural state, the torsion spring 23 can make the clamping arms 24 tilt towards the outside of the belt conveyor 17.

[0026] On both sides above the belt conveyor 17, there are also converging plates 18. The converging plates 18 have extension parts extending downward to the front end of the belt conveyor 17. The front end of the extension part is in the shape of an open flared opening. Grooves are provided inside the converging plates 18. Pressing plates 20 are provided in the grooves. An attaching spring 19 is provided between the converging plates 18 and the pressing plates 20. The attaching spring 19 is located in the inner groove of the converging plates 18. Usually, one carrier 21 on the surface of the belt conveyor 17 is located at the front end position of the extension part of the converging plates 18.

[0027] When the electrolytic capacitor in the transfer groove 8 in the weighing structure is a qualified product, the weighing structure records that the number of qualified electrolytic capacitors increases by one. Then the qualified electromagnetic column 11 is electrified, and the transfer groove 8 tilts towards the end of the qualified electromagnetic column 11. The qualified electrolytic capacitor slides into one carrier 21 at the front end of the belt conveyor 17. Among them, the electrolytic capacitor leads are located between the clamping arms 24, and the shell is located outside the clamping arms 24. Then the belt conveyor 17 starts the distance between two adjacent carriers 21. During the start of the belt conveyor 17, the clamping arms 24 move from the front end of the flared opening of the converging plates 18 to between the pressing plates 20. Under the action of the pressing plates 20, the clamping arms 24 gather together and clamp the electrolytic capacitor leads between the clamping arms 24. Then, the qualified electromagnetic column 11 is powered off, and the transfer groove 8 resets and continues to receive the electrolytic capacitors to be processed. The attaching spring 19 keeps a certain clamping force between the clamping arms 24 to prevent the electrolytic capacitor between them from falling due to vibration during the movement.

[0028] As Figure 1 and Figure 4As shown, the cutting structure includes a receiving plate 25, which is located above the end of the belt conveyor 17. There are two parallel receiving plates 25. Above the center between the receiving plates 25, there is a limiting plate 26. A triangular shape is formed between the receiving plate 25 and the limiting plate 26. The front end of the limiting plate 26 bends upward. Below the end of the receiving plate 25, there is also a cutting assembly 27 and a finished product box 33. At the end of the limiting plate 26, there is also a proximity switch 34.

[0029] The cutting assembly 27 includes a cutting cylinder 28 and a docking cylinder 29, which are arranged opposite to each other. The end of the cutting cylinder 28 is connected to a blade 31, and the end of the docking cylinder 29 is connected to a docking block 30. When the clamping arm 24 carries the electrolytic capacitor and moves to the end of the belt conveyor 17, the housing of the electrolytic capacitor extends between the receiving plate 25 and the limiting plate 26. When the clamping arm 24 continues to move along with the belt conveyor 17, it will lose the pressing force of the pressing plate 20 on it. Under the action of the torsion spring 23, they separate from each other and disengage from the electrolytic capacitor. The electrolytic capacitor located between the receiving plate 25 and the limiting plate 26 is driven by the next arriving electrolytic capacitor and is conveyed to the ends of the receiving plate 25 and the limiting plate 26. When the proximity switch 34 detects that there is an electrolytic capacitor at the ends of the receiving plate 25 and the limiting plate 26, the cutting cylinder 28 and the docking cylinder 29 extend, and the blade 31 cuts off the leads of the electrolytic capacitor. The cut electrolytic capacitor falls into the finished product box 33 below the receiving plate 25 for storage. When the set amount of electrolytic capacitor processing is reached, the stepping motor 6 and the belt conveyor 17 stop working.

[0030] The description of the present invention is given for purposes of illustration and description, and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for specific purposes.
