[0031] After the light source placed in the moving seat 103 is subjected to glue dispensing operation on the glue dispensing table, the light source is moved along the track to the detection table for detection of the fluorescent glue 501 after glue dispensing. The detection table is provided with a detection station 101, a glue supplementing station 102 and a glue reducing station 104, which are sequentially and spacedly arranged along the extension direction of the track.

[0032] A camera 200 is arranged above the detection station 101, the camera 200 shoots image information of the light source in the moving seat 103 and transmits the image information to a control for image recognition to determine whether the fluorescent glue 501 on the light source meets the set requirements; a glue supplementing head 300 is arranged above the glue supplementing station 102 and moves up and down to supplement the fluorescent glue 501 on the light source; and a glue reducing head 400 is arranged above the glue reducing station 104 and moves up and down to reduce the fluorescent glue 501 by picking up the fluorescent glue 501 on the light source.

[0033] The light source automatic glue supplementing and reducing equipment provided above, after glue dispensing on the glue dispensing table, the moving seat 103 with the light source enters the detection table, the image information is shot by the camera 200 for detection of the fluorescent glue 501 on the light source, according to actual needs, the moving seat 103 moves to the glue supplementing station 102, the glue supplementing head 300 is used for glue supplementing, the moving seat 103 moves to the glue reducing station 104, the glue reducing head 400 is used for glue reducing, so that the fluorescent glue 501 of the manufactured light source is detected and meets the set requirements, and the quality of the light source is ensured.

[0034] The inner side wall of the positioning groove 1032 is provided with an elastic layer 1031, the light source comprises a substrate 500 and a dam 502 formed on the substrate 500, the dam 502 encloses a light emitting area on the substrate 500, the light emitting area is provided with a light emitting chip, and a fluorescent glue 501 is formed in the light emitting area by dispensing, the fluorescent glue 501 covers the light emitting chip, and the outer periphery of the substrate 500 abuts on the elastic layer 1031.

[0035] In this way, the substrate 500 of the light source abuts on the elastic layer 1031, facilitating the placement and taking of the light source, and avoiding damage to the substrate 500 during the placement or taking of the light source, and the moving seat 103 ensures that the light source is in an elastic buffering state during movement, avoiding damage to the light source.

[0036] A plurality of glue strips 1033 are protruded on the elastic layer 1031, the glue strips 1033 are arranged along the circumference of the positioning groove 1032, the plurality of glue strips 1033 are arranged in an up-down interval, and the adjacent glue strips 1033 have an embedded interval; the outer periphery of the substrate 500 is embedded in the embedded interval, and the glue strips 1033 abut on the substrate 500 from top to bottom.

[0037] By arranging the plurality of glue strips 1033, the outer periphery of the substrate 500 is embedded in the embedded interval formed by the adjacent glue strips 1033, which can better elastically hold the substrate 500, so that the light source is always in an elastic buffering state during movement.

[0038] In this embodiment, the fluorescent glue 501 on the light source is in the enclosed area of the glue strips 1033 and has an interval with the glue strips 1033. In this way, the arrangement of the glue strips 1033 will not block the fluorescent glue 501.

[0039] In this embodiment, the bottom of the glue supplement head 300 is recessed upward to form a glue supplement cavity 302 with an open bottom, the top of the glue supplement cavity 302 is provided with a glue supplement outlet 304, the glue supplement outlet 304 is communicated with a glue supplement device through a glue supplement flow channel; when supplementing the fluorescent glue 501 on the light source, the glue supplement head 300 moves downward to cover the fluorescent glue 501 on the light source, the fluorescent glue 501 is placed in the glue supplement cavity 302, and the glue supplement device extrudes the glue into the glue supplement cavity 302 through the glue supplement outlet 304 and supplements the fluorescent glue 501.

[0040] In this way, when the surface of the fluorescent glue 501 of the light source after dispensing is in a concave state, the extrusion through the glue supplement outlet 304 is alternately supplemented, and the uniform flow of the glue after supplementing can be ensured by using the automatic fluid flow state of the glue.

[0041] The bottom of the glue supplementing head 300 is provided with an upwardly recessed mounting groove 303, and when the glue supplementing head 300 is covered on the fluorescent glue 501 on the light source, the top of the dam 502 is embedded in the mounting groove 303. In this way, the glue supplementing cavity 302 can be in a vertically aligned state with the fluorescent glue 501, thereby ensuring the accuracy of the glue supplementing.

[0042] When the glue supplementing head 300 is covered on the fluorescent glue 501 on the light source, the top of the glue supplementing cavity 302 has a glue supplementing gap with the fluorescent glue 501 on the light source. In this way, the glue extruded out of the glue supplementing outlet 304 can have sufficient space, so that the extruded glue can be uniformly coated on the fluorescent glue 501.

[0043] In the embodiment, the top of the glue supplementing cavity 302 is provided with a plurality of glue supplementing outlets 304, and the glue supplementing head 300 is provided with a horizontally flat buffer cavity 301 located above the glue supplementing cavity 302 and communicating with the glue supplementing cavity 302 through the glue supplementing outlets 304, and the buffer cavity 301 communicates with the glue supplementing device through the glue supplementing flow channel.

[0044] When the glue supplementing head 300 is covered on the fluorescent glue 501 on the light source, the glue supplementing device injects glue into the buffer cavity 301 through the glue supplementing flow channel, and when the buffer cavity 301 is filled with glue, the glue in the buffer cavity 301 is injected into the glue supplementing cavity 302 through the glue supplementing outlets 304.

[0045] In this way, glue supplementing can be realized at multiple positions, and the glue supplementing efficiency is improved. Furthermore, by providing the buffer cavity 301, when the buffer cavity 301 is filled with glue, the glue in the buffer cavity 301 is extruded out of the multiple glue supplementing outlets 304 into the glue supplementing cavity 302, which ensures that the glue extruded out of the multiple glue supplementing outlets 304 can be synchronously coated on the fluorescent glue 501, thereby ensuring that the surface of the fluorescent glue 501 after glue supplementing is smoother.

[0046] In the embodiment, the glue reducing head 400 is made of metal, and the bottom of the glue reducing head 400 has a glue adhering surface 401 in a spherical shape. When the glue adhering surface 401 abuts against the fluorescent glue 501, since the fluorescent glue 501 has not yet solidified and is in a fluid state, the fluorescent glue 501 will be partially adhered to the glue adhering surface 401 and be carried upward by the glue adhering surface 401, thereby realizing the glue reducing operation. The glue reducing head 400 is made of metal, and subsequent surface cleaning and the like can be realized.

[0047] In the embodiment, the middle part of the glue absorbing surface 401 has a pointed spike 402 extending downward, and a plurality of recessed slots 403 are arranged on the glue absorbing surface 401, which are arranged around the outer periphery of the pointed spike 402 and spread throughout the glue absorbing surface 401; when the glue reducing head 400 moves downward to the fluorescent glue 501 on the light source, the pointed spike 402 is inserted into the fluorescent glue 501, the recessed slots 403 of the glue absorbing surface 401 abut on the fluorescent glue 501 downward, and part of the fluorescent glue 501 is absorbed.

[0048] Since the surface of the fluorescent glue 501 has surface tension, when the glue absorbing surface 401 abuts on the surface of the fluorescent glue 501, in order to better bond with the fluorescent glue 501, the surface of the fluorescent glue 501 is pierced by the pointed spike 402 to destroy the surface tension, and then the plurality of recessed slots 403 are arranged to better bond the fluorescent glue 501 with the glue absorbing surface 401, facilitating the glue reducing operation.

[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
