Description

Technical Field

[0001] This utility model relates to the technical field of automated production feeding equipment for chip mounters, specifically a precision feeder with a HOME function. Background Technology

[0002] The chip mounter feeder is an important device in the chip mounter used for automatic transport and positioning of electronic components. It is mainly responsible for accurately transporting components packaged in reels, tubes, or trays to the pick-up position for the mounting head to pick up. The feeder uses a stepper motor, cylinder, or electronic control mechanism to precisely advance the components at a set pitch, ensuring that the chip mounter process is high-speed, stable, and continuous. Its precise structure and rapid response make it one of the key components for achieving automated, efficient, and high-precision chip mounter operation.

[0003] However, current chip mounter feeders mainly consist of belt drives, air cylinder linkage drives, and gear reducer drives, which have a certain impact on accuracy and feeding speed. They are no longer suitable for the increasingly smaller chip mount components on the market, and neither the feeding speed nor the feeding accuracy can meet market demands. In view of this, we propose a precision feeder with a HOME function. Utility Model Content

[0004] The purpose of this invention is to provide a precision feeder with a HOME function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision feeder with a HOME function, comprising a base plate, wherein a feeding assembly is provided on the side wall of the base plate, and the feeding assembly includes:

[0006] A stepper motor, wherein a gear set is fixedly connected to the output end of the stepper motor;

[0007] Paper tape with steel teeth, wherein the side wall of the paper tape with steel teeth is fixedly connected to a HOME point;

[0008] A HOME sensor is fixedly connected to the side wall of the base plate, and an electronic board is fixedly connected to the side wall of the base plate.

[0009] Preferably, a tearing wheel assembly is fixedly connected to the side wall of the base plate, and the tearing wheel assembly is located on the upper side of the base plate.

[0010] Preferably, the stepper motor is fixedly connected to the side wall of the base plate, and the stepper motor is electrically connected to the electronic board.

[0011] Preferably, the gear set has several stages of gears that mesh with each other. The first stage of gear is fixedly connected to the output end of the stepper motor, and the shaft of the last stage of gear is fixedly connected to the shaft of the paper tape steel toothed plate.

[0012] Preferably, the HOME sensor is located next to the paper tape toothed plate, and the HOME sensor is set on the side of the paper tape toothed plate away from the stepper motor, with the HOME point set as the origin.

[0013] Preferably, the HOME sensor is electrically connected to the electronic board, and the HOME sensor is fixedly connected to the electronic board. The number of teeth that need to be compensated is compared with the standard value and stored in the register of the electronic board, so that the steel toothed plate that drives the paper tape travels a precise distance for each tooth.

[0014] Preferably, the waste bin is fixedly connected to the side wall of the base plate, and the waste bin is located on the side of the tearing wheel assembly away from the stepper motor.

[0015] Compared with the prior art, this utility model provides a precision feeder with a HOME function, which has the following advantages:

[0016] 1. This precision feeder with HOME function uses a stepper motor to drive a gear set through a feeding component. Compared with traditional belt drive, it has the characteristics of faster response and more accurate rotation angle. At the same time, the HOME sensor detects the rotation of the paper tape steel tooth plate and calculates compensation values ​​through software to further improve feeding accuracy, meet the normal picking up of small components and eliminate or reduce gear errors.

[0017] 2. This precision feeder with HOME function calculates the compensation data for each tooth by comparing it with the standard value and storing it in the register of the electronic board. This ensures that the travel distance of each tooth of the steel toothed plate that drives the paper tape is accurate. The compensation value is stored locally, eliminating the need for recalculation each time. This avoids recalibration every time the device is started, improves the startup response speed, and maintains data consistency during operation. Attached Figure Description
