[0031] For ease of understanding of the present application, the present application will be described more comprehensively below with reference to the relevant attached drawings. Embodiments of the present application are shown in the attached drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present application is thorough and comprehensive.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

It should be understood that in addition to the orientation shown in the drawings, spatial relationship terms also include different orientations of the device during use and operation. For example, if the device in the attached drawings is flipped, an element or feature described as "under" or "beneath" or "below" another element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "under" and "below" can include both the upper and lower orientations.

[0034] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediate element. In the following embodiments, "connection", if there is an electrical signal or data transmission between the connected circuits, modules, units, etc., should be understood as "electrical connection", "communication connection", etc.

[0035] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprising", "including" or "having", etc., specify the presence of the stated features, integers, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts or combinations thereof.

[0036] As Figures 1 - 6 shown, a coaxial package laser diode module manufacturing process appearance detection device includes a base 1, on which an X-axis slide rail, a Y-axis slide rail and a Z-axis slide rail are provided. Among them: the Y-axis slide rail is arranged on the base 1, the X-axis slide rail is erected above the base 1 in the form of a gantry, and the Z-axis slide rail is slidably connected to the X-axis slide rail.

[0037] As Figure 7 shown, since the laser diode module product can observe the packaged chip from two angles, namely, top view and side view, the product needs to be detected from the top view and the side view to confirm the integrity of the packaged chip. A first CCD lens 5 and a second CCD lens 6 are respectively arranged on the Z-axis slide rail. The first CCD lens 5 is arranged downward, and the second CCD lens 6 is arranged obliquely downward. The first CCD lens 5 and the second CCD lens 6 form an angle to take appearance photos of the module from different angles. The module to be detected is fixed on a fixture assembly, and the fixture assembly is slidably mounted on the Y-axis slide rail. The XYZ-axis slide rails together constitute the alignment and shooting of the CCD lens for different modules.

[0038] Specifically, a fixing plate 7 is slidably arranged on the Z-axis slide rail. An installation plate 8 is arranged on the fixing plate 7. The first CCD lens 5 and the second CCD lens 6 are arranged on the installation plate 8, and the second CCD lens 6 is located at the lower side of the first CCD lens 5.

[0039] In this solution, adjusting components are respectively connected between the first CCD lens 5, the second CCD lens 6 and the installation plate 8. The adjusting components include a first fine-tuning member 9 and a second fine-tuning member 10. The first fine-tuning member 9 adjusts the position of the first CCD lens 5 or the second CCD lens 6 in the X-axis and Z-axis directions, and the second fine-tuning member 10 adjusts the angle between the first CCD lens 5 or the second CCD lens 6 and the vertical direction.

[0040] The internal structures of the first fine-tuning member 9 and the second fine-tuning member 10 are prior arts. For details, refer to a visible light lens optical axis fine-tuning platform of a fusion detection system disclosed in the patent number CN106405777B, in which the horizontal direct fine-tuning device and the horizontal fine-tuning rotation device respectively correspond to the first fine-tuning member 9 and the second fine-tuning member 10.

[0041] Specifically, a positioning plate 11 is slidably connected to the Y-axis slide rail. A fixture plate 12 is provided on the positioning plate 11, and a fixture module 13 is provided on the fixture plate 12. The positioning plate 11 is provided with positioning holes arranged in a horizontal and vertical array. A positioning block 14 is screwed and fixed on the positioning plate 11. The fixture plate 12 can also be threadedly connected to the positioning plate 11 and can also be snap-fitted and fixed within the frame formed by the positioning blocks 14. The positioning block 14 is provided with an adjustment groove, and a screw screwed into the positioning hole is inserted into the adjustment groove.

[0042] In one embodiment, the fixture module 13 uses a fishbone fixture, and fishbone-shaped grooves 15 are provided on both sides of the fishbone fixture.

[0043] When the fishbone fixture is used to place the COC product for detection:

[0044] 1. Place the fishbone fixture with the COC product on the fixture plate and fix it through the positioning block. Up to 6 fishbone fixtures can be placed at one time.

[0045] 2. The system selects the corresponding array of the fishbone fixture. Start the device, and the device moves through the X, Y, and Z-axis slide rails to align the COC product directly below the downward-view CCD lens (only the front of the COC product needs to be detected).

[0046] 3. By adjusting the direction knobs of the first fine-tuning component and the second fine-tuning component, the CCD lens clearly captures an image of the front of the COC product.

[0047] 4. Then, the system confirms and judges the image to distinguish between good products and defective products.

[0048] 5. The system automatically moves to the next COC product through the X, Y, and Z-axis slide rails.

[0049] 6. Repeat steps 4-5. Complete the detection of all COC products on the fishbone fixture.

[0050] Feeder ( Figure 1 the fixture module in it) when placing the laser diode module product for detection:

[0051] 1. Place the feeder with the laser diode module product on the fixture plate fixed at the bottom of the device and fix the feeder through the positioning block.

[0052] 2. The system selects the corresponding array of the feeder. Start the device, and the device moves through the X, Y, and Z-axis slide rails to align the laser diode module product directly below the downward-view CCD lens and the side CCD lens. (The laser diode module product needs to detect images of the downward view and the side view)

[0053] 3. By adjusting the direction knobs of the first fine-tuning component and the second fine-tuning component, the downward-view CCD lens and the side CCD lens clearly capture the downward view and the side view that need to be detected for the laser diode module product.

[0054] 4. Then the system makes a confirmation and judgment on the image to distinguish between good products and defective products.

[0055] 5. The system automatically moves to the next laser diode module product through the X, Y, and Z-axis slides.

[0056] 6. Repeat steps 4 to 5. Complete the detection of the laser diode module products held by the fishbone fixture.

[0057] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
