Description

Technical Field

[0001] The utility model relates to capacitor assembly equipment, in particular to a sequencing mechanism for a capacitor assembly process. Background Art

[0002] The assembly process in the capacitor production process is an important part of the capacitor manufacturing process. This step mainly involves assembling the aluminum shell, capacitor core package and rubber plug on the outside of the capacitor. Specifically, the capacitor core package is inserted into the aluminum shell, and then the rubber plug is inserted into the aluminum shell to block the capacitor core package. There are generally two small holes on the rubber plug, corresponding to the two pins on the capacitor core package. Therefore, when assembling the rubber plug, it is necessary to ensure that the two pins pass through the two small holes, and then lock the aluminum shell. After completing these operations, the capacitor is basically formed.

[0003] In the assembly process, precise operation and strict quality control are crucial. Since the pins of the capacitor core package need to match the small holes on the rubber plug, the pins and the rubber plug need to be corrected during the feeding process to ensure that the directions of both are fixed during output. In this way, in the subsequent automated assembly process, reliable installation and controllable yield can be ensured. The currently commonly used automatic discharge and feeding equipment is a vibration plate feeding mechanism. For granular materials such as capacitor core packages, the vibration plate feeding mechanism can efficiently sort and output, and ensure that the pins are all facing one side, but it cannot control the circumferential angle of the capacitor core package, that is, the distribution angle of the two pins cannot be controlled, so the circumferential angle of the capacitor core package also needs to be sorted. For this reason, the automated equipment used in the assembly process in the capacitor production industry needs to be equipped with a capacitor core package sorting mechanism. The current sorting mechanism structure is relatively complex, the production cost is relatively high, and the more complex the mechanism, the more likely it is to have mechanical failures. Summary of the invention

[0004] The utility model provides a sequencing mechanism for a capacitor assembly process, which solves the problem in the prior art that the sequencing mechanism for the assembly process is relatively complex in structure and prone to mechanical failure.

[0005] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a sorting mechanism for a capacitor assembly process, used for sorting capacitor core packages, characterized in that it includes a linear vibration table, a transport track arranged on the upper side of the linear vibration table, a conveying trough arranged on the transport track, and a guide assembly relatively fixed to the upper side of the conveying trough, the rear end of the transport track is provided with a push-out groove vertically penetrating the conveying trough, a push block is slidably arranged in the push-out groove, and a push-out mechanism for driving the push block to reciprocate is arranged on the transport track; the guide assembly includes a first guide plate and a second guide plate, a pin guide groove is formed between the two guide plates, the pin guide groove is parallel to the length direction of the conveying trough and is located at the center position of the conveying trough, the front end of the first guide plate is provided with a first guide slope, the front end of the second guide plate is provided with a second guide slope, and the two guide slopes are staggered front and back; the outer diameter of the capacitor core package is adapted to the width of the conveying trough.

[0006] The utility model needs to be used in conjunction with a vibration plate automatic feeding device, the output end of the vibration plate automatic feeding device is connected to the front end of the conveying trough on the utility model, so that the capacitor core package output from the vibration plate automatic feeding device can be smoothly vibrated into the conveying trough, and then under the vibration of the linear vibration table, the capacitor core package in the conveying trough can continue to move slowly to one side of the ejection trough, and the capacitor core packages in the conveying trough all move with the pins facing upward, and the pin rotation angles of these capacitor core packages are different. As they continue to move backward, the pins that deviate from the center line of the conveying trough will gradually approach the first guide bevel located on the front side. Under the guidance of the first guide bevel, the capacitor core package with the wrong posture will gradually rotate the angle until the two pins are close to the center line, and then under the guidance of the second guide bevel, the two pins slide into the pin guide groove. At this time, the rotation posture of the capacitor core package is fixed, and it moves into the ejection trough with this posture, and is finally pushed out by the push block to enter the next workstation.

[0007] Furthermore, the push-out mechanism includes a cylinder seat fixed to the rear end of the transport track and a cylinder arranged on the cylinder seat, the cylinder rod of the cylinder is connected to the push block, and a cover plate extending toward one side of the cylinder is arranged on the push block and close to the conveying trough. The first function of the cover plate is that during the push-out process of the push block, the cover plate can block the conveying trough to prevent the capacitor core package in the conveying trough from invading the push-out trough; the second function of the cover plate is that during the reset process of the push block, the rear end of the cover plate will abut against the cylinder seat, thereby playing a limiting role.

[0008] Furthermore, the front end of the push block is provided with an ejection portion and a pin stopper for preventing the capacitor core package from rotating. The ejection portion is used to abut against the capacitor core package to push it to move axially along the ejection slot, while the pin stopper does not directly contact the pins, and a small gap is generally left between the two. The main function of the pin stopper is to limit the relative position of the two pins, thereby preventing the capacitor core package from rotating significantly as a whole during the process of being pushed by the ejection portion.

[0009] Furthermore, an arc-shaped portion adapted to the outer contour of the capacitor core package is provided on the ejection portion away from the conveying groove. The arc-shaped portion serves to increase the contact area of ​​the capacitor core package and avoid large deformation of the capacitor core package caused by excessive local pressure.

[0010] Therefore, compared with the prior art, the utility model has the following characteristics: 1. Under the guidance of the first guide bevel, the capacitor core package with an incorrect posture will gradually rotate until the two pins are close to the center line, and then under the guidance of the second guide bevel, the two pins slide into the pin guide groove. At this time, the rotation posture of the capacitor core package is fixed and output in this posture, so that the utility model has the advantages of simple structure and reliable operation.
