Description

Technical Field

[0001] This utility model relates to the field of electronic component assembly technology, and in particular to a plug-in component, a laser, and an automated installation device. Background Technology

[0002] Semiconductor lasers (UV light sources) are the core components in laser direct imaging (LDI) equipment. The product quality of semiconductor lasers and the consistency of mass production directly affect the product quality of laser direct imaging equipment.

[0003] Semiconductor lasers typically include a circuit board, a water-cooled plate, and multiple laser head components. The circuit board needs to accommodate other components, so the water-cooled plate is provided with heat-conducting ribs. The water-cooled plate is stacked on the circuit board, and the heat-conducting ribs abut against the upper surface of the circuit board. There is space between the lower surface of the water-cooled plate and the upper surface of the circuit board to accommodate the components. The water-cooled plate is also provided with multiple mounting ports, and the laser head components are inserted one by one into the mounting ports. The electrical connection pins of the laser head components are inserted one by one into the pin holes of the circuit board to achieve connection.

[0004] Traditionally, semiconductor lasers were assembled manually. While the electrical pins of the laser head components could be inserted relatively accurately into the pin holes by human operators, manual assembly was inefficient. Manufacturers attempted to use automated equipment to automate the assembly process. Image acquisition devices were used to capture the positions of the mounting ports and their corresponding pin holes. A robotic arm was then used to lift the laser head components and move them to the corresponding positions for installation. However, because there is space between the lower surface of the water-cooled plate and the upper surface of the circuit board to accommodate the components, shadows appeared in the images of the pin hole positions captured by the image acquisition devices. This resulted in low analysis accuracy and low assembly precision, leading to a decrease in product yield. Utility Model Content

[0025] like Figures 1 to 7 As shown, a plug-in component 100 according to a first aspect embodiment of the present invention includes a base 110 and at least one conductive pin 120. The base 110 is provided with at least one through hole 130 penetrating the upper and lower end faces. The pin 120 is correspondingly disposed in the through hole 130. The tail end of the pin 120 protrudes from the lower end face of the base 110 for plugging into the pin hole of the circuit board 200. The head end of the pin 120 is located in the through hole 130 and is used for conductive contact with the electrical connection pin of the component.

[0026] Among them, such as Figure 1 , 2 As shown, the base 110 can be made of insulating and heat-resistant resin material, and can be in the shape of a frustum or a truncated cone, with a certain height so that the lower end of the base 110 can be supported on the circuit board 200, while the upper end of the base 110 can be close to the water-cooled plate 300.

[0027] The present invention relates to a plug-in component 100, wherein the base 110 is plugged into the pin hole of the circuit board 200 through the pin core 120. The base 110 has a certain height to be close to the water-cooled plate 300, which can reduce the shadow in the mounting port 310 and improve the accuracy of image analysis of the water-cooled plate 300 acquired from the top by the image acquisition module. It is suitable for automated assembly. The electrical connection pins of the component can be more accurately inserted into the through hole 130 to make conductive contact with the first end of the pin core 120, thereby realizing the electrical connection of the component to the conductive layer on the circuit board 200 through the pin core 120.

The chamfer 140 can be a bevel or an arc. When the automated installation device extracts the component and drives the component's electrical connection pin to be inserted into the through hole 130, the chamfer 140 can allow for error tolerance. When there is a small positional deviation between the electrical connection pin and the through hole 130, it can also guide the electrical connection pin to be inserted into the through hole 130 more accurately.

[0029] The laser according to the second aspect embodiment of the present invention, such as Figures 4 to 7 As shown, the device includes a circuit board 200, a water-cooled plate 300, multiple laser head elements 400, and a connector 100 disclosed in any of the above embodiments. The bottom surface of the water-cooled plate 300 is provided with heat-conducting ribs 320. The water-cooled plate 300 is disposed on the circuit board 200, and the heat-conducting ribs 320 thermally abut against the upper surface of the circuit board 200. The circuit board 200 is provided with multiple pin holes. The base 110 is disposed on the upper surface of the circuit board 200, and the... The needle core pins 120 are inserted into the pin holes one by one. The water-cooled plate 300 is provided with a plurality of mounting ports 310 corresponding to the plug-in components 100. The upper end face of the base 110 is close to the lower end of the mounting port 310. The laser head components 400 are inserted into the mounting ports 310 one by one. The electrical connection pins of the laser head components 400 are inserted into the through holes 130 one by one, and the electrical connection pins are in conductive contact with the first end of the needle core pins 120.

[0030] The laser head element 400 can be a conventional laser diode emitter. Two electrical connection pins can extend from the bottom of the laser head element 400. Specifically, the electrical connection pins are set according to the actual model of the laser head element 400, which is not specifically limited here. A water-cooling channel can be provided in the water-cooling plate 300. The water-cooling channel is arranged in a meandering manner at various positions of the water-cooling plate 300. The water-cooling plate 300 has a water-cooling outlet 330 and a water-cooling inlet 340 that are connected to the water-cooling channel. When water flows through the water-cooling channel, it can achieve heat exchange through the wall of the water-cooling plate 300. The heat of the circuit board 200 can be conducted to the water through the heat-conducting ribs 320. The heat of the laser head element 400 can also be conducted to the water through the wall of the water-cooling plate 300. The heat-conducting ribs 320 can be integrated with the water-cooling plate 300.

[0031] In this utility model laser, the upper end face of the base 110 is close to the lower end of the mounting port 310, which reduces the shadow in the mounting port 310 when the image acquisition module acquires the image of the water-cooled plate 300 from the top, improving the accuracy of image analysis. It is suitable for automated assembly. The electrical connection pins of the laser head element 400 can be more accurately inserted into the through hole 130 to make conductive contact with the first end of the pin core 120, thereby realizing the electrical connection pins of the element to the conductive layer on the circuit board 200 through the pin core 120. This design can realize automated assembly, improve production efficiency and assembly yield.

[0032] When the laser head component 400 is installed in the mounting port 310, it will exert a certain force on the water-cooled plate 300. In order to prevent the water-cooled plate 300 from pressing against the circuit board 200 and causing wear to the circuit board 200, in some embodiments of this utility model, a thermally conductive pad is provided between the thermally conductive rib 320 and the upper surface of the circuit board 200. The thermally conductive pad abuts against the thermally conductive rib 320 and the upper surface of the circuit board 200 respectively. The thermally conductive pad can be made of rubber material with good thermal conductivity.

[0033] Typically, the laser head element 400 can have multiple electrical connection pins. In some embodiments of this utility model, one of the mounting ports 310 is directly opposite the end of multiple through holes 130. After the insertion component 100 is provided, the image acquisition module can more accurately obtain the position information of multiple through holes 130 in the same mounting port 310, thereby facilitating that the electrical connection pins on the laser head element 400 can be inserted into the through holes 130 one by one.

[0034] In some embodiments of this utility model, the heat-conducting rib 320 is elongated, and a plurality of mounting openings 310 are arranged along the length of the heat-conducting rib 320.

[0035] The heat-conducting ribs 320 are supported on the upper surface of the circuit board 200. The long strip-shaped heat-conducting ribs 320 can ensure the stability of the water-cooled plate 300 at various positions. The multiple mounting ports 310 are arranged along the length of the heat-conducting ribs 320, which can ensure that the multiple mounting ports 310 are basically located on the same horizontal plane, thereby improving the accuracy of the acquired images.

The control module is connected to the image acquisition module and the extraction and assembly module respectively to install the laser disclosed in any of the above embodiments at the installation station.

[0037] The base can be made of sheet metal, and the installation station can be a flat surface or groove on the base. The image acquisition module can be a conventional CCD camera, and the control module can include a processor such as an MCU or CPU and its associated circuitry. The extraction and assembly module is equipped with a robotic arm that can extract the circuit board 200, the connector 100, the water-cooled plate 300, and the laser head element 400. First, the circuit board 200 is placed on the installation station, and then each connector 100 is installed one by one. The pin core 120 of the plug-in component 100 is placed in the corresponding position on the circuit board 200, and the pin core 120 is inserted into the pin hole on the circuit board 200.

Finally, the laser head components 400 are installed one by one in the mounting port 310, and the connecting pins are inserted one by one into the through hole 130.

[0038] This utility model relates to an automated installation device for automating the assembly of lasers, thereby improving production efficiency and assembly yield.

[0039] In some embodiments of this utility model, the image acquisition module is located above the installation station and faces the installation station, thereby reducing the probability of image distortion.

The X-axis and Y-axis are parallel to the horizontal plane and perpendicular to each other. The lifting mechanism can be a conventional cylinder transmission mechanism, motor belt transmission mechanism, gear and rack transmission mechanism, etc., used to drive the robot arm to move up and down, so that the connecting pin can be vertically inserted into the through hole 130 and the needle core pin 120 can be vertically inserted into the pin hole.
