Description

Technical Field

[0001] The present invention relates to the technical field of aluminum electrolytic capacitor production, and specifically to an automatic feeding and conveying method and device for aluminum electrolytic capacitors. Background Art

[0002] Aluminum electrolytic capacitor is a common electronic component with large capacitance and wide application fields, such as power supply filtering and circuit decoupling. It is composed of an aluminum cylinder, a liquid electrolyte and a bent aluminum strip, and has positive and negative polarity. Although the leakage is large and the stability is average, it is widely used in consumer electronics, industrial control and other fields due to its low cost and moderate performance. In the production process of aluminum electrolytic capacitors, in order to improve production efficiency, an automatic feeding and conveying device is usually used to convey the aluminum electrolytic capacitors. For example, the application number: CN201010175145.7 discloses an automatic feeding and conveying method and device for aluminum electrolytic capacitors, which feeds and conveys aluminum electrolytic capacitors through an automatic feeding and conveying device.

[0003] In the production process of aluminum electrolytic capacitors, in order to prevent external short circuit or leakage of the capacitor and ensure its safety, it is necessary to cover the surface of the capacitor with an insulating film. Therefore, the capacitor needs to be fed into the coating mechanism through an automatic feeding and conveying device; However, existing automatic feeding and conveying devices usually use conveyor belts to transport capacitors, and direct contact between materials and mechanical parts such as conveyor belts will increase the risk of wear and damage to materials. Therefore, they are gradually transformed into pneumatic conveying. Pneumatic conveying uses a fan or compressor to generate airflow through a pipe or conveying pipe to push materials (such as capacitors) to the destination. However, due to the large number of capacitors transported at one time, the capacitor closest to the pneumatic power source will block part of the airflow, so that the capacitor farthest from the pneumatic power source can only receive less wind force, and as the moving distance increases, the wind force felt by the capacitor is gradually reduced, resulting in the capacitor farthest from the pneumatic power source moving slower. At the same time, the capacitor closest to the pneumatic power source may collide with the capacitor in front due to its faster speed, causing damage to the terminals of the capacitor in front. Summary of the invention

[0013] The automatic feeding and conveying method of aluminum electrolytic capacitors includes the following steps: S1. First, push the containing block onto the pushing plate through the loading mechanism, push the capacitor onto the containing block, and then push the containing block and the capacitor into the conveying pipe; S2.

[0015] 2. Through the power auxiliary component, the auxiliary wind force blowing forward at an angle to the containing block can be automatically adjusted according to the speed at which the containing block passes through the speed meter.

[0016] 3. Through the set lubrication component, when each holding block is just moved forward stably at the same speed by the auxiliary wind force, the speed of the holding block is further detected by the second speed meter. When it is detected that the moving speed of the holding block is not within a preset speed range, it indicates that the friction between the bottom end of the holding block and the feed pipe is large, thereby reducing the initial moving speed of the holding block. Therefore, the first electric telescopic rod is controlled by the PLC controller to start to squeeze the lubricating liquid to the bottom end of the holding block, reducing the friction between the holding block and the inner wall of the feed pipe, which helps to maintain a stable conveying speed and prevent the speed from slowing down due to excessive friction.

[0028] Among them, the top of the support plate 22 is fixedly connected to two supporting vertical plates 28, the top of one of the supporting vertical plates 28 is fixedly connected to a horizontal plate 29, the top of the horizontal plate 29 is fixedly connected to a conveying block 215 with the same cross section as the containing block 13, a cavity is provided inside the conveying block 215, a conveying structure is arranged in the cavity, and the conveying structure includes a conveyor belt and a driving source for driving the conveyor belt, the top of the conveyor belt is fixedly connected to a partition 216 for pushing the capacitor and controlling the position of the capacitor, the top of the conveying block 215 is provided with a conveying groove 210 connected to the cavity, and the conveying groove 210 is in sliding contact with the partition 216, and each operation time of the motor is to step-by-step convey the containing block 13 to push the capacitor to the containing block 13 at a fixed distance, and the distance between the two capacitors is controlled by the partition 216 to prevent the collision between the two capacitors and cause damage to the capacitor; Furthermore, a conveying plate 211 for conveying the holding block 13 is fixedly connected to the top of another supporting vertical plate 28, a placement groove 212 for accommodating the gear 145 is provided at the top of the conveying plate 211, a baffle 213 is fixedly connected to the side of the conveying plate 211 away from the conveying block 215, and a second electric telescopic rod 214 for pushing the holding block 13 is fixedly connected to the outer wall of the baffle 213 on the side close to the conveying block 215, the PLC controller is connected to the second electric telescopic rod 214, the third electric telescopic rod 23, and the motor electrical signal to form a feeding circuit, and the second electric telescopic rod 214 is pre-set, and the moving distance each time is consistent, which is just enough to push the holding block 13 onto the pushing plate 24.

[0029] It should be noted that every four containing blocks 13 are divided into a group during transportation, and the rear end face of the containing block 13 at the rearmost in a group is fixedly connected with a wind-bearing plate 3, which can provide a faster moving speed for the containing blocks.

[0030] The working principle of the present invention is as follows: First, the second electric telescopic rod 214 is controlled to start through the PLC controller to push the multiple holding blocks 13 to move forward, and then the front holding block 13 is sent to the top of the push plate 24, and then the conveying structure is driven by the starting motor to drive the partition 216 to move forward, pushing the capacitor so that the capacitor is pushed onto the holding block 13, and then the intelligent vacuum pump 164 is controlled to exhaust air, and then the air in the negative pressure groove 161 is extracted, and the capacitor is further fixed on the upper surface of the holding block 13 by negative pressure adsorption through the negative pressure hole 162, and then the third electric telescopic rod 23 is controlled to start through the PLC controller, and then the push plate 24 is pushed to move upward until the push plate 24 enters the feed port 27, so that the holding block 13 and the capacitor enter the conveying pipe 11; After the containing blocks 13 and the capacitors enter the conveying pipe 11, the power fan 12 is controlled to start to provide power wind for the containing blocks 13, so as to blow the containing blocks 13 to drive the capacitors forward, and then repeat the above steps to allow more containing blocks 13 and capacitors to enter the conveying pipe 11 and convey them forward, by dividing every four containing blocks 13 into a group, and the rearmost containing block 13 in a group has a wind-bearing plate 3.

[0031] In the process of the capacitors being transported by the holding block 13, since a large number of capacitors are transported at one time, the capacitor at the rear will block part of the airflow, so that the capacitor in front can only receive less wind force, resulting in a slower moving speed of the capacitor in front, which may hit the capacitor in front and cause damage to the terminal of the capacitor in front. Therefore, in the process of the capacitors being transported by the holding block 13, since the rearmost holding block 13 has the wind-bearing plate 3, the rearmost holding block 13 receives more wind force, so the moving speed is faster. When the holding block 13 moves, the gear 145 moves on the second tooth plate 26 to rotate the gear 145, so that the rotating rod and the transmission rod 148 rotate, and the rotating shaft 1410 rotates through the transmission rod 148 and the bevel gear pair, and the other two rotating shafts 1410 rotate synchronously through the two belt drive assemblies, so that the three exhaust fans 1411 rotate synchronously, and the wind blown out by the power motor is drawn into the special-shaped slot 163, and then the wind is blown to the holding block 13 in front through the air outlet 147. At the same time, the infrared rays emitted by the infrared transmitter in front of the rearmost holding block 13 are received by the infrared receiver 142 behind the front holding block 13, and the distance between the two holding blocks 13 is calculated by the calculation module in the PLC controller. When it is detected that the distance between the two holding blocks 13 is closer, the current controlled by the PLC controller to pass through the electromagnetic plate 1414 is greater, and the repulsive force of the electromagnetic plate 1414 on the magnetic plate embedded in the L-shaped wind shield 1412 is greater, and then the air outlet 147 is blocked by the two L-shaped wind shields 1412, making the air outlet 147 smaller. Since the air volume is consistent, according to According to the principles of fluid mechanics, when a fluid passes through a smaller opening, its flow velocity will increase, resulting in an increase in wind force. Therefore, the wind force blowing to the front containing block 13 will increase, thereby increasing the moving speed of the front containing block 13. With the above process, the containing block 13 will gradually blow out wind force forward, so that the moving speed of the capacitor driven by the front containing block 13 will increase. Since the wind is blown to the front containing block 13 by the rear containing block 13, a reaction force will be generated on the rear containing block 13. Since the blown wind force will be absorbed by the front containing block 13, the reaction force will be greatly reduced and will not be enough to affect the movement of the rear containing block 13.

[0032] And at regular intervals, a first speed meter 152 will measure the moving distance of each holding block 13 and convert the detected speed signal into an electrical signal and transmit it to the PLC controller, and blow lateral auxiliary wind to the holding block 13 through the n-shaped air outlet duct 1512 and the air outlet hood 1513. This control mechanism ensures that the holding block 13 has sufficient wind power and a stable speed. When the measured speed is close to the set speed, the PLC controller controls the n-shaped fan 1511 to operate at a lower power, and the thrust provided to the holding block 13 becomes smaller to maintain the preset speed. Conversely, if the measured speed is significantly different from the set speed, the PLC controller will increase the power of the fan, so that the n-shaped air outlet duct 1512 and the air outlet hood 1513 provide a stronger airflow, providing additional power for the holding block 13 to ensure that all the holding blocks 13 move stably at the same speed.

[0033] When the multiple holding blocks 13 are just affected by the auxiliary wind force, they should move forward stably at the same speed. When the holding block 13 is further tested by the second speed meter 171, when it is detected that the moving speed of the holding block 13 is not within the range of the preset moving speed, it indicates that the static friction coefficient between the bottom end of the holding block 13 and the feed pipe 11 is large, resulting in a reduction in the moving speed of the holding block 13. Therefore, the PLC controller is combined with the measured speed of the holding block 13, and the required amount of lubricant is calculated by the calculation module, and then the PLC controller is used to calculate the amount of lubricant required. The first electric telescopic rod 175 is controlled to start and extend to a certain length (the extension length is calculated by the calculation module according to the amount of lubricant required to be replenished and then the required extension length of the first electric telescopic rod 175 is calculated), the normally closed solenoid valve is opened, and the lubricant is discharged into the inner bottom wall of the feed pipe 11 through the liquid outlet pipe 173 and the liquid outlet cross plate 29 by squeezing the squeezing plate 176, and then the bottom of the containing block 13 is contaminated with the lubricant by moving the containing block 13, thereby reducing the friction resistance between the containing block 13 and the inner bottom wall of the feed pipe 11 to ensure the moving speed of the containing block 13.

[0034] The automatic feeding and conveying method of aluminum electrolytic capacitors includes the following steps: S1. First, the loading mechanism 2 pushes the containing block 13 onto the pushing plate 24, pushes the capacitor onto the containing block 13, and then pushes the containing block 13 and the capacitor into the conveying pipe 11; S2, the holding block 13 and the capacitor are transported by the power fan 12. During this process, the holding block 13 at the rear continuously blows the wind at the rear side to the holding block 13 at the front through the wind power conversion power assembly 14 to provide power; S3, the power auxiliary component 15 adaptively provides auxiliary power for the containing block 13 according to the moving speed of the containing block 13; S4, the lubricating component 17 provides lubricating liquid to the bottom end of the containing block 13 according to the moving speed of the containing block 13 after receiving the auxiliary power.
