[0006] Furthermore, the material guiding channel is higher at the front and lower at the back, and is inclined at a preset angle.

[0007] Furthermore, a front material sensor is correspondingly provided at the front end of the feeding channel.

[0008] Furthermore, a rear material sensor is provided at the material taking port.

[0009] Furthermore, the cross-sections of the material guiding channel and the material feeding channel are in an inverted T shape.

[0010] Furthermore, there are multiple groups of material guiding channels, material feeding channels and conveyor belts.

DETAILED DESCRIPTION

[0022] It should be noted that, unless there is a conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention is further described in detail below with reference to the drawings and specific embodiments.

[0023] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship and movement status of the various components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0025] Please refer to Figures 1 to 8 The feeding device for patch components of an embodiment of the present invention includes a material guide channel, a feeding channel, a conveyor belt and a driving mechanism.

[0026] The drive mechanism drives the conveyor belt. The front end of the feed channel connects to the rear end of the guide channel. The conveyor belt is located at the bottom of the feed channel and transports surface mount components into the channel. The upper layer of the conveyor belt is located at the bottom of the feed channel.

[0027] A material reclaiming port is located at the end of the feeding channel to facilitate the robot to grab the material. A material stop is located at the end of the reclaiming port. The stop stops the material being fed to the reclaiming port, making it easier for the robot to grab the material.

[0028] As an embodiment, the material guide channel is higher in front and lower in the back and is tilted at a preset angle. The tilted design facilitates the material entering the material guide channel to move more smoothly into the feeding channel.

[0029] In one embodiment, a front material sensor is provided at the front end of the feed channel. This sensor detects the presence of material at the front end of the feed channel. A rear material sensor is provided at the feed inlet. This sensor detects the presence of material at the feed inlet to prevent the robot from grabbing empty material. Both the front and rear material sensors can be through-beam sensors.

[0030] As an embodiment, the cross-section of the material guide and feeding channels is an inverted T-shape, that is, the material guide and feeding channels are slot-shaped, with openings at the top and both the front and back ends. The open tops of the material guide and feeding channels facilitate user observation of the material inside the channels and also facilitate the production, processing, and assembly of the components (the channels can be constructed using only two to three parts).

[0031] As an embodiment, the guide channel, feeding channel, and conveyor belts are provided in multiple groups to improve the conveying efficiency. The multiple groups of conveyor belts can be synchronously driven by a group of driving mechanisms.

[0032] As an embodiment, the driving mechanism includes a driving wheel, a driven wheel and a motor transmission assembly for driving the driving wheel to move. The driven wheel and the driving wheel are respectively arranged at the front and rear ends of the feeding channel.

[0033] The working principle of the present invention is as follows: when in use, the present invention is arranged between a feeding table and a robot; the feeding table blows the patch components into the material guide channel from the front end, and the patch components in the material guide channel enter the feeding channel under the influence of inertia, blowing, and gravity (the inclination of the material guide channel); the patch components in the feeding channel are driven by the conveyor belt to the material removal port at the end and are taken away by the material removal robot.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
