Description

Technical Field

[0001] The invention belongs to the field of Raman detection equipment, in particular to a Raman detection equipment for LED chips. Background Art

[0002] LED chips may have certain defects in large-scale production, such as lattice distortion and impurity introduction. These defects may have adverse effects on the performance of the chip. In order to confirm the quality of the chip, the LED chips after large-scale production will be sampled and tested. The method used is non-destructive and non-contact Raman detection equipment. Its main principle is based on the Raman scattering phenomenon. When a certain frequency of laser is irradiated to the surface of the LED chip, the molecules in the substance will absorb or release part of the energy, vibrate in different ways and degrees, and then scatter light of different frequencies. The spectrum test is performed by detecting the light emitted by the LED chip structure, thereby completing the detection process of the LED chip.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] Embodiment 1 like Figure 1-Figure 4 As shown, a Raman detection device for LED chips according to an embodiment of the present invention comprises a power supply box 1 and an extension workbench 2 fixedly installed on one side of the power supply box 1, a Raman detection component 3 is movably installed on the extension workbench 2, a detection table 4 is movably installed inside the Raman detection component 3, a conveying table 5 is installed on the side of the detection table 4, a component to be detected 6 is transported on the conveying table 5, the component to be detected 6 comprises a plurality of transport frames 1 61 and a transport frame 2 62 movably installed on the side of the transport frame 1 61, a plurality of transport frames 2 62 are provided, transparent sheets 63 are movably installed on the plurality of transport frames 1 61 and the transport frame 2 62, a transparent frame 631 is installed above the transparent sheet 63, and the transparent frame 631 is used to place the LED chip.

[0025] Specifically, when a large number of LED chips need to be accurately detected, an extended workbench 2 and a Raman detection component 3 are required. The power supply box 1 is used to power the Raman detection component 3. The Raman detection component 3 is an existing traditional technology. First, the laser source is irradiated onto the LED chip, and then the optical elements in the optical microscope system are used to guide and focus the laser and collect the scattered light of the sample. These elements are also involved in the process of magnification and focusing to ensure that the laser is accurately irradiated onto the sample. When a certain frequency of laser is irradiated onto the surface of the LED chip, the molecules in the substance will absorb or release part of the energy, vibrate in different ways and degrees, and then scatter light of different frequencies. The spectrum test is performed by detecting the light emitted by the LED chip structure, thereby completing the detection process of the LED chip. In order to ensure the detection effect, the chip position needs to be debugged, and the magnification and focal length of the optical element also need to be adjusted. Adjustment, so the traditional Raman detection equipment detects one by one, which is inefficient. In order to detect the qualified rate of the same chip, it is only necessary to adjust the Raman detection equipment once and then maintain the position of each subsequent chip. In the present device, the transparent sheet 63 is placed on the transport frame 1 61 or the transport frame 2 62. First, the position of the transparent sheet 63 is determined, and then the LED chip is placed inside the transparent frame 631 to determine the position of the chip. Then, the transport frame 1 61 and the transport frame 2 62 are detachably connected. After the multiple transport frames 1 61 and the transport frames 2 62 are detachably connected, they are placed on the conveying table 5. Through a certain displacement, the component 6 to be detected is moved to the position of the detection table 4 to ensure that the LED chip placed on each transparent sheet 63 is consistent with the chip position detected by the Raman detection component 3 for the first time. Then, through continuous transportation, the chip can be quickly detected through the Raman detection component 3.

[0026] like Figure 2 As shown, the Raman detection component 3 includes a Raman observation component 31 movably installed above the extension workbench 2, and a plurality of observation lenses 32 are fixedly installed on the side of the Raman observation component 31. The Raman detection component 3 includes a multi-angle adjustment platform 33 rotatably installed below the extension workbench 2, and a plurality of Raman detection probes 34 are fixedly installed below the multi-angle adjustment platform 33. The plurality of Raman detection probes 34 are used to adjust the observation magnification and focal length of the chip.

[0027] Specifically, the traditional technical solution requires multiple observation lenses 32 and Raman observation components 31 to cooperate in detection, while in the present device, the positions of multiple Raman detection probes 34 can be adjusted through a multi-angle adjustment platform 33 to make them correspond to the chip, and multiple Raman detection probes 34 are provided. The observation magnification and focal length of each Raman detection probe 34 vary greatly. By replacing different Raman detection probes 34, the observation magnification and focal length can be quickly adjusted. Optical elements are arranged inside the Raman detection probe 34, which can accurately adjust the magnification and focal length, thereby more accurately detecting the LED chip.

[0028] like Figure 3 As shown, the testing platform 4 includes a fixed seat 44 fixedly installed above the bottom of the extended workbench 2, a displacement bar 43 is slidably installed above the fixed seat 44, a lifting platform 41 is lifted and lowered above the displacement bar 43, a screw rod 42 is spirally connected between the lifting platform 41 and the displacement bar 43, a through groove 411 is opened inside the lifting platform 41, and a component groove 412 is also opened inside the lifting platform 41, the through groove 411 and the component groove 412 are connected, a movable gear 413 is movably installed inside one side of the component groove 412, and a gear driving mechanism 45 is movably installed inside the other side, and a plurality of positioning components 7 are installed above the lifting platform 41, and the positioning component 7 is used to position the LED chip.

[0029] Specifically, the distance between the lifting platform 41 and the displacement bar 43 can be adjusted by rotating the screw rod 42. A through groove 411 is opened inside the lifting platform 41. When the LED chip is detected, the LED chip will be directly above the through groove 411, which is conducive to the laser irradiation of the LED chip. The drive of the tooth drive mechanism 45 can move the component 6 to be detected in the component groove 412 by tooth meshing, and cooperate with the conveying platform 5 to transport the component 6 to be detected. Each transportation moves the component 6 to be detected a certain distance. First, the LED chip on a transport frame 1 61 is detected by the Raman detection component 3. After the component 6 to be detected moves, the LED chip on the next adjacent transport frame 2 62 is detected by the Raman detection component 3, which can improve the detection efficiency of the same LED chip.

[0030] like Figure 4-Figure 5As shown, racks 1 611 are fixedly installed on both sides of the transport frame 1 61, racks 2 621 are fixedly installed on both sides of the transport frame 2 62, and the transport frame 1 61 and the transport frame 2 62 are gear-engaged in the component groove 412 through the racks 1 611 and the racks 2 621. Two handles 612 are fixedly installed on the top of the transport frame 1 61, and a pneumatic component 614 is also installed below the handles 612. The pneumatic component 614 and the positioning component 7 are at the same horizontal height, grooves 613 are provided on both sides of the transport frame 1 61, and convex strips 622 are fixedly installed on both sides of the transport frame 2 62. The convex strips 622 are magnetically installed in the grooves 613, and two installation grooves 632 are provided inside the transparent sheet 63, and the transparent sheet 63 is placed on the top of the transport frame 1 61 through the cooperation of the installation grooves 632 and the handles 612.

[0031] Specifically, the transport frame 1 61 and the transport frame 2 62 are components made of the same structure, and the two are connected by magnetic attraction inside the groove 613 through the convex strip 622. The transport frame 1 61 and the transport frame 2 62 can also achieve a shell detachable connection similar to magnetic attraction through spiral connections at the four corners. The length of the installation groove 632 is consistent with the length of the handle 612, but the width of the installation groove 632 is greater than the width of the handle 612. In this case, it can be ensured that the transparent sheet 63 is quickly placed on the transport frame 1 61, but at this time the transparent frame 631 is not necessarily in the center position of the transport frame 1 61, and the position of the transparent sheet 63 can be adjusted by the positioning component 7 to ensure that the transparent sheet 63 is placed on the transport frame 1 61. The bright frame 631 and the LED chip are at the center position on the transport frame 1 61. At this time, the position of this group of LED chips is the same as that of the LED chips detected for the first time, that is, there is no need to debug the test element of the Raman detection component 3. After the LED chips on this group of transport frame 1 61 are detected, the component to be detected 6 is displaced to a certain extent through the engagement of the component to be detected 6 with the movable gear 413 and the conveying action of the conveying platform 5. At this time, the transport frame 2 62 adjacent to the transport frame 1 61 is moved to the center of the component groove 412, and the transparent sheet 63 and the LED chip on the transport frame 2 62 are debugged again through the positioning component 7 to facilitate the detection of the LED chips.

[0032] like Figure 6 As shown, the pneumatic component 614 includes a fixing strip 6142 fixedly installed below the corresponding handle 612, a semicircular rubber airbag strip 6141 is fixedly installed on the side of the fixing strip 6142 facing the outer side of the transport frame 61, a plurality of air grooves 6143 are provided inside the fixing strip 6142, the plurality of air grooves 6143 are used to connect the semicircular rubber airbag strip 6141 and the fixing strip 6142, and an air injection port 6144 is fixedly installed on one side of the fixing strip 6142 facing the positioning component 7.

[0033] Specifically, when a transport frame 1 61 or a transport frame 2 62 moves to the center of the component groove 412, the pneumatic component 614 corresponds to the position of the positioning component 7, and the positioning component 7 can inject gas into the interior of the fixing strip 6142 through the gas injection port 6144. After the gas inside the fixing strip 6142 is full, it is transmitted to the semicircular rubber airbag strip 6141 through multiple gas grooves 6143, so that the semicircular rubber airbag strip 6141 is inflated and expanded, and changes from a contracted state to a semicircular expanded state. When the semicircular rubber airbag strip 6141 is inflated, it will squeeze the inner wall of the installation groove 632, thereby causing the transparent sheet 63 to move, and the transport frame 1 61 When the upper two pneumatic components 614 are both inflated, the transparent sheet 63 is equivalent to bearing the thrust at both ends, thereby ensuring that the chip on the transparent sheet 63 can be located at the center of the transport frame 61. The chip position is adjusted, and the center horizontal height of the semicircular rubber airbag strip 6141 is higher than the highest point of the transparent sheet 63. When the semicircular rubber airbag strip 6141 is inflated, it will push the transparent sheet 63, but the semicircular axis point of the semicircle of the semicircular rubber airbag strip 6141 always plays a downward pressure role, avoiding the transparent sheet 63 from being driven to move and causing horizontal height fluctuations, thereby affecting the subsequent Raman detection of the Raman detection component 3.

[0034] Embodiment 2 like Figure 7-Figure 8 As shown, compared with Example 1, another implementation of the present invention is: the positioning component 7 includes a component bar 71 fixedly installed above the lifting platform 41 and a movable component 73 movably installed inside the component bar 71, and the component bar 71 is provided with a revealing strip groove 72 on the side facing the gear drive mechanism 45, and the gear drive mechanism 45 includes a fixed motor 451 fixedly installed inside the lifting platform 41 and a half gear 452 connected to the top of the fixed motor 451 through an axis, the half gear 452 is located inside the component groove 412, and a half gear 2 453 is connected to the top of the half gear 452 through an axis, and the half gear 2 453 and the revealing strip groove 72 are at the same horizontal height.

[0035] The movable member 73 is set as a strip-shaped object, and a movable rack 731 is fixedly installed on the side of the movable member 73 facing the half gear 2 453, a fixed air pipe 732 is fixedly installed inside the movable member 73, an air injection head 733 is fixedly installed at one end of the fixed air pipe 732, a telescopic air pipe 734 is installed at one end of the fixed air pipe 732, a compression spring 735 is installed on the outside of the telescopic air pipe 734, and the telescopic air pipe 734 and the compression spring 735 are both installed inside the member strip 71.

[0036] Specifically, in the present device, when a transport frame 1 61 is at the center of the component slot 412, the half gear 1 452 is in meshing state with the rack 1 611, but when the half gear 1 452 rotates clockwise again, the position without teeth of the half gear 1 452 will appear on the side of the rack 1 611, and at this time, the half gear 2 453 is in meshing state with the moving rack 731, but when the half gear 2 453 rotates clockwise again, the position without teeth of the half gear 2 453 will appear on the side of the moving rack 731. On one side of the strip 731, the telescopic air tube 734 and the compression spring 735 are stretched, and one end of the gas injection head 733 is located inside the gas injection port 6144. The telescopic air tube 734 can be supplied with gas through an external air pump, so that the gas passes through the telescopic air tube 734, the fixed air tube 732, and the gas injection head 733 into the fixed strip 6142, so that the semicircular rubber airbag strip 6141 is inflated. After the chips on this group of transport frame 61 are detected, the semi-gear 452 is driven by the fixed motor 451. The toothless outer side of the half gear 1 452 will not drive the movement of the transport frame 1 61, and the toothless outer side of the half gear 2 453 will no longer mesh with the moving rack 731. Under the restoring force of the telescopic air pipe 734 and the compression spring 735, the moving member 73 moves away from the pneumatic member 614 inside the member bar 71. When the half gear 1 452 and the half gear 2 453 continue to rotate, the half gear 1 452 will mesh with the outer side of the transport frame 1 61, and the half gear 2 453 will not mesh with the moving rack 731. The outer side of the wheel 2 453 is meshed with the movable rack 731. At this time, the rotation of the half gear 1 452 drives the transport frame 1 61 to move until the next group of adjacent transport frames 2 62 moves to the center of the component groove 412. The previous meshing rotation of the half gear 2 453 allows the gas injection head 733 to be inside the gas injection port 6144 set in the transport frame 2 62. This reciprocating cycle can be used to debug and locate the position of the chip, and the gas injection structure can also play the role of gas injection synchronously, which simplifies the detection process of a large number of chips.

[0037] Working principle: When a large number of LED chips need to be accurately detected, the extended workbench 2 and the Raman detection component 3 are required. The power supply box 1 is used to power the Raman detection component 3. The Raman detection component 3 first allows the laser source to irradiate the LED chip, and then uses the optical elements in the optical microscope system to guide and focus the laser and collect the scattered light of the sample. These elements are also involved in the process of amplification and focusing to ensure that the laser is accurately irradiated on the sample. When a certain frequency of laser is irradiated on the surface of the LED chip, the molecules in the substance will absorb or release part of the energy, vibrate in different ways and degrees, and then scatter light of different frequencies. The spectrum test is performed by detecting the light emitted by the LED chip structure, and then the LED chip is completed. During the detection process, in order to ensure the detection effect, the position of the chip needs to be debugged, and the magnification and focal length of the optical element also need to be adjusted. Therefore, the traditional Raman detection equipment detects one by one, which is inefficient. In order to detect the qualified rate of the same type of chips, it is only necessary to adjust the Raman detection equipment once and then maintain the position of each subsequent chip. In this device, the transparent sheet 63 is placed on the transport frame 1 61 or the transport frame 2 62. First, the position of the transparent sheet 63 is determined, and then the LED chip is placed inside the transparent frame 631 to determine the position of the chip. Then, the transport frame 1 61 and the transport frame 2 62 are detachably connected, and multiple transport frames 1 61 and 2 62 are detachably connected and placed on the conveyor table. 5, through a certain displacement, the component to be detected 6 is moved to the position of the detection platform 4 to ensure that the LED chip placed on each transparent sheet 63 is consistent with the chip position detected by the Raman detection component 3 for the first time, and then the chip can be quickly detected by the Raman detection component 3 through continuous transportation. The transport frame 1 61 and the transport frame 2 62 are components made of the same structure. The two are connected by magnetic attraction inside the groove 613 through the convex strip 622. The transport frame 1 61 and the transport frame 2 62 can also be connected by spiral connection at the four corners to achieve a shell detachable connection similar to magnetic attraction. The length of the installation groove 632 is consistent with the length of the handle 612, but the width of the installation groove 632 is greater than the width of the handle 612. In this case, it can be ensured that the transparent sheet 63 The transparent sheet 63 is quickly placed on the transport frame 1 61, but the transparent frame 631 is not necessarily in the center position of the transport frame 1 61 at this time. The position of the transparent sheet 63 can be adjusted by the positioning component 7 to ensure that the transparent frame 631 and the LED chip are in the center position of the transport frame 1 61. At this time, the position of this group of LED chips is the same as the LED chips detected for the first time, that is, there is no need to debug the test element of the Raman detection component 3. After the LED chips on this group of transport frame 1 61 are detected, the component to be detected 6 is moved to a certain extent through the meshing of the component to be detected 6 and the movable gear 413 and the conveying action of the conveying platform 5. At this time, the transport frame 2 62 adjacent to the transport frame 1 61 is moved to the center of the component slot 412.The transparent sheet 63 and the LED chip on the second transport frame 62 are debugged again by the positioning component 7 to facilitate the detection of the LED chip.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
