Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to a belt feeder. Background Art

[0002] The tape feeder is the most commonly used feeder in the placement machine. The traditional structures include wheel type, claw type, pneumatic type and multi-pitch electric type. Now it has developed into a high-precision electric type. Compared with the traditional structure, the high-precision electric type has higher transmission accuracy, faster feeding speed, more compact structure, more stable performance, and greatly improves production efficiency.

[0003] For example, a belt material feeder is disclosed in the Chinese utility model patent publication number (CN205305345U), which includes a feeder body and a material tray. The feeder also includes a cantilever and a locking component for supporting the material tray on the feeder body. A support hole is opened at one end of the cantilever away from the feeder body. The locking component fixes the material tray at the support hole of the cantilever, and the position of the material tray can be adjusted along the support hole. This utility model solves the problem that the feeder of the prior art is heavy when being transported and moved, and the operator needs two hands to carry the feeder. The feeder body also needs to carry the tray-packed materials, which is inconvenient to operate. In addition, during the transportation process, the materials may be damaged by contact, resulting in the scrapping of the materials. At the same time, large tray-packed materials are heavy. If the bottom contacts the SMT machine platform, friction will be generated between them. The feeder will be affected when pulling the materials, causing the SMT machine to alarm and unable to produce normally, thereby affecting the production efficiency. However, this patent cannot screen the materials, and the materials are not convenient to automatically adjust to the same angle as the feeder, resulting in low feeding efficiency and affecting practicality.

It solves the problem in the patent that materials cannot be screened and the materials are not convenient to automatically adjust to the same angle as the feeder, resulting in low feeding efficiency and affecting practicality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a belt feeder, comprising a frame, a mounting plate is fixed to the lower surface of the frame, a feeding mechanism for cyclically feeding materials is arranged on the frame, and a conveying mechanism for conveying materials is arranged on the mounting plate;

[0007] Furthermore, the frame is in the shape of a rectangular parallelepiped with a hollow interior and a missing upper surface and a missing lower surface.

[0008] Furthermore, the first inclined plate is located in front of the second inclined plate, and the sum of the widths of the first inclined plate and the second inclined plate matches the distance between the inner walls on the front and rear sides of the frame.

[0009] Furthermore, the screening component includes a feeding rack, which is fixed to the rear inner wall of the frame, a baffle is fixed to the upper surface of the feeding rack, and a material taking port is opened on the front side of the feeding rack.

[0010] Furthermore, there are two material taking ports, which are symmetrically distributed front to back about the central axis of the material feeding rack.

[0011] Furthermore, the conveying mechanism includes a motor, which is fixed to the back side of the mounting plate, and the output shaft of the motor passes through and extends to the front side of the mounting plate, and is fixed with a first transmission roller, the outer side of the first transmission roller is transmission-connected to the conveyor belt, the front side of the mounting plate is rotationally connected to the second transmission roller via a bearing, the inner side of the other end of the conveyor belt is transmission-connected to the outer side of the second transmission roller, the front side of the mounting plate is rotationally connected to the first bending roller via a bearing, the first bending roller is transmission-connected to the lower surface of the conveyor belt, the front inner wall of the frame is rotationally connected to the second bending roller via a bearing, and the second bending roller is transmission-connected to the inner top wall of the conveyor belt.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The belt feeder, through the cooperation of the first inclined plate, allows the material to slide onto the conveyor belt under the action of its own gravity, so as to lift the material. Through the cooperation of the first guide plate, the moving direction of the lifted material can be guided, so that the material can be introduced into the feeding rack. The material with the same direction as the feeding rack enters the feeding rack, and the material with a different direction slides along the second inclined plate to the second guide plate, and the material is guided to the first inclined plate again, so as to work in a cycle and improve the feeding efficiency.

[0015] 2. The belt feeder can drive the first transmission roller to rotate through the cooperation of the motor, thereby driving the conveyor belt to drive.
