Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0040] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0041] The present application will be further described below in conjunction with the drawings and specific embodiments, but not as a limitation of the present application.

[0042] Specific implementation method one: the following will be described in conjunction with Figs. 1 to 3 In this embodiment, the 3D LED preparation system comprises a flow line transmission unit, a tool jig 207, a glue spraying device 203, a pre-curing device 204, a curing device 213, a positioning peg 209, an image acquisition unit, and a flip bonding mechanism 211.

[0043] The glue spraying device 203, the pre-curing device 204, the image acquisition unit, and the curing device 213 are sequentially and suspendedly arranged along the line on the flow line transmission unit according to the process steps, and the positioning peg 209 is arranged on the inner side of the flow line transmission unit below the image acquisition unit; the flip bonding mechanism 211 is arranged on the outer side of the flow line transmission unit;

[0044] The flow line transmission unit is used to transmit the tool jig 207 along the process steps in sequence; the tool jig 207 is provided with a jig positioning soft pad 208, and a plurality of parallel and equidistant workpiece areas are enclosed by the jig positioning soft pad 208, and a plurality of LED modules 300 are respectively embedded into each workpiece area;

[0045] The glue spraying device 203 is used to spray glue on the LED modules 300 on the tool jig 207 transmitted to this process position;

[0046] The pre-curing device 204 is used to pre-cure the LED modules 300 after spraying glue;

[0047] The positioning peg 209 is used to fix the tool jig 207 at this process position, and the tool jig 207 is released after bonding the polarized 3D film 100, and the tool jig 207 continues to be transmitted to the next process position;

[0048] The flip bonding mechanism 211 is used to attract the polarized 3D film 100 and flip to bond the polarized 3D film 100 to the plurality of LED modules 300 on the tool jig 207, and the flip bonding mechanism 211 releases the polarized 3D film 100 and flips back after alignment;

[0049] The image acquisition unit is used to acquire the image of the LED modules 300 fixed at the process position by the positioning peg 209, and is also used to acquire the image of the polarized 3D film 100 bonded on the LED modules 300 through the flip bonding mechanism 211, and to realize the alignment operation of the LED modules 300 and the polarized 3D film 100 accordingly, and to construct the 3D LED module 210 after alignment;

[0050] The curing device 213 is used for curing the 3D LED module 210.

[0051] The embodiment gives a pipeline processing system of the 3D LED module.

[0052] In the pipeline of the embodiment, the pipeline transmission unit includes the speed chain support 201 and the speed chain transmission chain 202, two speed chain transmission chains 202 are arranged side by side on the speed chain support 201, and the two speed chain transmission chains 202 are used for transmitting the tooling fixture 207. The speed chain transmission chain transmits the tooling fixture 207, but does not adopt a fixed mode, and the two are in sliding friction. When flowing to the positioning peg 209 for the bonding process, the tooling fixture 207 can be easily stopped at the process position and kept in sliding friction with the speed chain transmission chain 202, and can continue to flow after the bonding is completed.

[0053] The positioning peg 209 includes a frame, a hydraulic lifting unit, a gear unit, and a positioning detection unit. The frame is arranged below the speed chain support 201, and the hydraulic lifting unit, the gear unit, and the positioning detection unit are arranged on the frame. The positioning detection unit is used for detecting whether the tooling fixture 207 is transmitted to the current process position. When detection is detected, the hydraulic lifting unit drives the gear unit to rise and block the tooling fixture 207, so that the tooling fixture 207 is fixed at the current process position. After the alignment is completed, the hydraulic lifting unit drives the gear unit to descend, and releases the tooling fixture 207 to continue transmission on the chain. The positioning detection unit can be realized by using a conventional infrared detection. When the tooling fixture 207 is detected to pass above, the gear unit blocks the tooling fixture 207 to make it stay at the process position and wait for bonding. The gear unit can adopt a roller, which can limit the position of the tooling fixture 207 and will not produce discordant jamming, and is convenient for releasing the tooling fixture 207 to continue to flow. The gear unit is lifted and descended by the hydraulic lifting unit according to the instruction. The tooling fixture 207 is detected to rise, and the bonding process is ended to descend. The bonding process time can be predicted, and the tooling fixture 207 can be released in a timing manner. In the embodiment, the lifting and descending of the gear unit can also be driven by using a pneumatic lifting mode.

[0054] Further, the positioning peg 209 further includes a first light supplement unit 212 arranged on the frame and used for image acquisition compensation. When image acquisition is performed, the positioning peg 209 frame below the tooling fixture 207 is supplemented with light, and the effect is better.

[0055] The image acquisition unit comprises a CCD mobile support 205 and a CCD unit group 206. The CCD mobile support 205 is fixed above the speed chain support 201, and the CCD unit group 206 is arranged on the CCD mobile support 205. The CCD unit group 206 is used to acquire images of the LED module 300 and the polarized 3D film 100. The CCD mobile support 205 is a shelf arranged above the speed chain support 201. The shelf is suspended above the flow line. The purpose is to acquire images of the multiple LED modules 300 on the tooling fixture 207 blocked at the process position and to provide a basis for alignment with the polarized 3D film 100. The second acquisition target is to acquire images of the polarized 3D film 100 after lamination. According to the two images, the alignment preparation can be completed.

[0056] The flip lamination mechanism 211 comprises a low-density transparent net box adsorption platform 101, a lamination roller 103, a vacuum cavity 104, and a circular polarization layer 105. The low-density transparent net box adsorption platform 101, the lamination roller 103, the vacuum cavity 104, and the circular polarization layer 105 are fixed as an integral structure.

[0057] The lamination roller 103 is arranged inside the vacuum cavity 104. The lamination roller 103 is fixed on the left and right side walls through two sliding blocks 102. The sliding blocks 102 are embedded with sliding rails. The lamination roller 103 moves up and down along the sliding rails to change positions. The lamination roller 103 has two transparent sections 107. The size of the transparent sections 107 is greater than the pitch width of a single row or single column of the polarized 3D film 100.

[0058] The bottom plate of the vacuum cavity 104 is a soft low-density transparent net box adsorption platform 101. The polarized 3D film 100 is adsorbed on the low-density transparent net box adsorption platform 101 through vacuumization inside the vacuum cavity 104.

[0059] The circular polarization layer 105 is arranged above the top plate of the vacuum cavity 104.

[0060] The flip lamination mechanism 211 further comprises a flip mechanism and a torsion mechanism. The flip mechanism is used to flip and buckle on the tooling fixture 207 along the speed chain support 201. The torsion mechanism is used for plane torsion to adjust the angle of the polarized 3D film 100 to align with the LED module 300.

[0061] In this embodiment, the turnover bonding mechanism 211 is arranged outside the speed chain support 201, and in the daily state, one polarized 3D film 100 is adsorbed, the film faces upward, after the tooling fixture 207 flows over and is blocked by the positioning pin 209, the turnover bonding mechanism 211 is turned over to the inside of the speed chain support 201 on the tooling fixture 207, so that the polarized 3D film 100 is buckled on the plurality of LED modules 300 arranged on the tooling fixture 207, at this time, the image acquisition unit is used to acquire the image of the polarized 3D film 100, and whether the polarized 3D film 100 is aligned with the image of the LED module 300 is judged, if there is deviation, the polarized 3D film 100 is translated or twisted in the plane by using the twisting mechanism of the turnover bonding mechanism 211, so as to achieve the purpose of alignment of the two, and the twisting mechanism of the turnover bonding mechanism 211 can make the low-density transparent net box adsorption platform 101, the bonding roller 103, the vacuum cavity 104 and the circularly polarized layer 105 move as a whole, instead of twisting the polarized 3D film 100 alone.

[0062] The vacuum cavity 104 has only one side as a soft side wall, which is a low-density transparent net box adsorption platform 101, such as a mesh plate with a mesh size greater than 400, and the process of adsorbing the polarized 3D film 100 is as follows: the low-density transparent net box adsorption platform 101 of the vacuum cavity 104 is attached to the polarized 3D film 100, and then the vacuum cavity 104 is vacuumized, so that the polarized 3D film 100 is adsorbed by the low-density transparent net box adsorption platform 101 of the vacuum cavity 104. When the turnover bonding mechanism 211 is turned over to the tooling fixture 207, the polarized 3D film 100 is buckled on the LED module 300, at this time, the image acquisition unit is used to acquire two single-row or single-column polarized 3D film 100 images through the transparent section 107, and then the twisting unit is used for alignment, and then the roller 103 inside the vacuum cavity 104 is started to move along the slide to the polarized 3D film 100, as shown in Fig. 3 , the roller 103 moves down to the polarized 3D film 100 and then rolls horizontally to press the polarized 3D film 100 on the LED module 300, in the process of pressing, the vacuum state of the vacuum cavity 104 is destroyed, the adsorption force of the low-density transparent net box adsorption platform 101 to the polarized 3D film 100 disappears, so that the polarized 3D film 100 is pressed and stays on the LED module 300, and the 3D LED module 210 is constructed.

[0063] The process of the image acquisition unit acquiring two single row or single column polarized 3D film 100 images through the transparent section 107: the laminating roller 103 has two transparent sections 107, the size of the transparent section 107 is greater than the pitch width of the single row or single column of the polarized 3D film 100; and the transparent section 107 is made of acrylic or PC material, which is a material without phase difference, and the phase image of the polarized 3D film 100 can be presented through the circularly polarized layer 105. The image of the polarized 3D film 100 cannot be completely acquired, but the pitch image of the two single rows or single columns can be acquired through the two transparent sections 107, which is sufficient to match the image of the LED module 300. The flip lamination mechanism 211 also includes a second light supplement unit 106, which is arranged above the circularly polarized layer 105 and is used for image acquisition compensation.

[0064] After lamination is completed, secondary curing is performed; after the above steps are completed, the 3D LED module is taken out, and the above steps are completed synchronously.

[0065] Specific implementation method two: the following will be described in combination with Figs. 1 to 3 The present embodiment describes a 3D LED preparation method, which is realized based on the 3D LED preparation system described in embodiment one. The method includes the following steps:
