Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED chip technology, and in particular to an LED feeding relay mechanism and an LED feeding device. Background Technology
[0002] The number of robotic arms in existing SMT (Surface Mount Technology) placement equipment is increasing, and current SMT placement equipment can now place multiple LED chips simultaneously. Therefore, the requirements for LED chip feeding speed and efficiency in existing SMT placement equipment are also increasing.
[0003] Patent application number CN202411267478.0, entitled "LED Feeding Device, System and Control Method Thereof," discloses an LED feeding device, such as... Figure 1 As shown, the combination of the feeding platform and the conveying station enables the delivery of multiple LEDs at a time, with a fast feeding speed that greatly improves feeding efficiency.
[0004] However, the feeding platform of this device moves back and forth at high speed, and the feeding pipe on the platform vibrates at high frequency. Therefore, when the LED beads in the feeding platform are directly fed into the high-frequency vibrating feeding pipe by air blowing, there will be situations where the LED beads cannot be fed through. When the LED beads cannot be fed through or the feeding is not smooth, they will get stuck between the feeding platform and the feeding pipe. Once the feeding platform moves, it will knock and damage the LED beads stuck between the feeding platform and the feeding pipe. Utility Model Content
[0005] The technical problem to be solved by this utility model embodiment is to provide an LED feeding relay mechanism and an LED feeding device to solve the problem of LED beads being damaged by impact.
[0006] To solve the above-mentioned technical problems, this utility model embodiment proposes an LED feeding relay mechanism, including a relay platform with several front-to-back connecting receiving pipes arranged side by side on the relay platform.
[0007] Furthermore, the repeater station consists of a base and an upper cover.
[0008] Furthermore, the front end of the upper cover extends beyond the base plate.
[0009] Furthermore, one or more through holes are provided at the center of the front end of the top cover to facilitate the placement of LED beads.
[0010] Furthermore, it also includes a first laser beam sensor for detecting whether material is stuck on the feed side of the receiving pipe.
[0011] Furthermore, it also includes a second laser beam sensor for detecting whether material is stuck on the discharge side of the receiving pipe.
[0012] Furthermore, it also includes a material blowing module for blowing material into the receiving pipeline.
[0013] Furthermore, the receiving pipe has an opening at the top, and the blowing module consists of a blowing pipe and a fixing block. One end of the blowing pipe is located at the top of the receiving pipe, and the other end is connected to the fixing block.
[0014] Furthermore, a fixing block is installed on the relay platform, and an air passage is provided inside the relay platform. A connector for connecting to an external air source is provided on the relay platform, and the air passage is connected to the connector. The other end of the blowing pipe is connected to the air passage through the fixing block.
[0015] Accordingly, this utility model embodiment also provides an LED feeding device, including a feeding platform, a feeding station, and the aforementioned LED feeding relay mechanism, wherein the LED feeding relay mechanism is disposed between the feeding platform and the feeding station.
[0016] The beneficial effects of this invention are as follows: This invention adds a stationary receiving pipe between the high-speed moving feeding platform and the high-frequency vibrating feeding platform (the feeding pipe of the feeding platform). This allows the receiving pipe to be very close to the feeding platform, with a gap of only tens of micrometers. This ensures that the feeding platform smoothly blows the LED beads into the receiving pipe, which then blows them into the high-frequency vibrating feeding pipe. This invention has a simple structure and completely solves the problem of LED beads being damaged by impact in LED feeding devices. Attached Figure Description

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.
[0030] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0031] Please refer to Figures 2-7 The LED feeding relay mechanism of this utility model includes a relay platform. Several through-type receiving pipes are arranged side-by-side at equal intervals on the relay platform. This utility model adds a stationary relay platform between the feeding pipes of a high-speed moving feeding platform and a high-frequency vibrating feeding platform. The receiving pipes of the relay platform can be very close to the feeding platform, with a gap of tens of micrometers, thus ensuring that the feeding platform smoothly blows LED beads into the receiving pipes, which are then blown into the high-frequency vibrating feeding pipes by air. In specific implementations, the number of receiving pipes is the same as the number of feeding pipes on the feeding platform, and the spacing between the receiving pipes is the same as the spacing between the feeding pipes on the feeding platform. Because the number of receiving pipes is the same as the number of feeding pipes, even if the distance between the receiving pipes and the feeding pipes is about 0.4mm, the LED beads can be easily fed into the feeding pipes by air.
[0032] In one implementation, the relay station consists of a base and an upper cover, which facilitates manufacturing. In a specific implementation, grooves are cut into the base and upper cover, and these grooves form a material receiving pipeline.
[0033] In one implementation, the front end of the upper cover plate extends beyond the base. The front end of the upper cover plate is used to cover the upper part of the feeding trough of the feeding platform, preventing the LED beads in the feeding trough from being blown over, and also to limit the LEDs in the feeding trough; at the same time, sealing the upper part of the feeding trough allows the airflow blown out from the air hole A to act better on the LED beads, so that the LED beads can enter the receiving pipe more quickly and smoothly.
[0034] In one implementation, the upper cover plate has one or more through holes at the center of its front end to facilitate the placement of LED beads by a robotic arm. Preferably, there are two. The robotic arm grasps the LED beads, passes them through the through holes, and places them into the feeding slot of the feeding platform. In a specific implementation, the center of the front end of the upper cover plate can also be left open, using an open design as the through hole.
[0035] In one implementation, the LED feeding relay mechanism also includes a first laser beam sensor for detecting whether material is stuck on the feeding side of the receiving pipe (i.e., the side that connects to the feeding platform). When the first laser beam sensor detects that material is stuck between the feeding platform and the receiving pipe, it controls the feeding platform to stop moving and increases the blowing time; if the stuck LED is still not blown away, an alarm is triggered, and the issue is handled manually by engineers.
[0036] In one implementation, the LED feeding relay mechanism also includes a second laser beam sensor for detecting whether material is stuck on the discharge side of the receiving pipe (i.e., the side corresponding to the feeding platform). When the first laser beam sensor detects that material is stuck between the receiving pipe and the feeding pipe of the feeding platform, it controls the feeding platform to stop moving and increases the blowing time; if the stuck LED is still not blown away, an alarm is triggered, and the issue is handled manually by engineers.
[0037] In one implementation, the LED feeding relay mechanism also includes several blowing modules for blowing air into the receiving pipe. The receiving pipe has an opening at the top, meaning its cross-section is inverted T-shaped. Each blowing module consists of a blowing pipe and a fixing block. One end of the blowing pipe is located at the opening at the top of the receiving pipe, blowing air obliquely into the pipe (obliquely towards the discharge side). The other end of the blowing pipe is connected to the fixing block.
[0038] In one implementation, a fixing block is placed on a relay platform, and an air passage is provided inside the relay platform. A connector for connecting to an external air source is provided on the relay platform, and the air passage is connected to the connector. The other end of the blowing pipe is connected to the air passage through the fixing block.
[0039] Please refer to Figures 8-9The LED feeding device of this utility model includes a feeding platform, a feeding station, and an LED feeding relay mechanism. The structures of the feeding platform and feeding station can refer to existing technologies. The LED feeding relay mechanism is stationary between the feeding platform and the feeding station. The feeding platform moves back and forth at high speed, while the feeding station vibrates at high frequency; the distance between the two parts cannot be too close. This utility model uses the LED feeding relay mechanism as a conveying bridge between the feeding platform and the feeding station. Because the receiving pipe is stationary, the LED beads on the feeding platform can be smoothly fed into the receiving pipe and then from the receiving pipe to the feeding station, completely solving the problem of LED beads being damaged by impact.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
