Description

Technical Field

[0001] This utility model relates to the field of integrated circuits, and in particular to a Tray Scan detection device. Background Technology

[0002] In the chip testing and sorting process, the current loading and unloading handling mechanisms generally lack a real-time detection mechanism for chip status. Because it is impossible to determine the chip's orientation in the tray, preheating tray, or trolley before picking it up, chip tilting can easily lead to pick-up failure or chip damage. Similarly, after placing the chip, it is also impossible to effectively detect whether the chip is placed correctly, affecting the stability of subsequent processes. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a Tray Scan detection device.

[0004] A Tray Scan inspection device includes a laser reflection component, a camera laser component, and a loading / unloading suction head component; the laser reflection component and the camera laser component are respectively connected to the loading / unloading suction head component, the camera laser component captures an image of the laser emitted by the laser reflection component on the object being photographed, the irradiation direction of the camera laser component is movable, and the angle between the laser emitted by the laser reflection component and the camera laser component is variable.

[0005] In this solution, the object being photographed by the laser emitted by the laser reflection component refers to the carrier used to hold chips, such as the tray and / or the tray scan mechanism and / or the feeding device and / or the discharging device of the tray scan mechanism. The chips held by the tray and / or the tray scan mechanism and / or the feeding device and / or the discharging device of the tray scan mechanism may be misaligned or not at all.

[0006] This invention allows for the capture of chip placement postures, enabling the entire feeding process to be monitored and preventing the omission of critical steps. It is highly adaptable, with movable camera laser assembly and adjustable laser reflection assembly to accommodate inspection needs at different locations. The detection is precise and efficient, quickly identifying incorrect chip placement or missing components, reducing subsequent process failures. Camera-based image capture at high speeds does not affect machine efficiency. For chips requiring code reading, the camera saves space. Depending on the application scenario, the camera laser assembly and laser reflection assembly can be installed in different orientations.

[0007] Preferably, the laser reflection component is installed below the loading / unloading suction head assembly, and the camera laser component is installed above the loading / unloading suction head assembly. This design is compact and efficient, as the components are integrated around the loading / unloading suction head assembly, eliminating the need for a large additional installation space. Furthermore, detection and loading / unloading can be synchronized; during the loading / unloading process, the lower laser reflection component and the upper camera laser component can simultaneously complete the detection, reducing the time required for separate detection steps.

[0008] Preferably, the laser reflecting assembly includes a fixing plate R, a fixing plate L, a reflector, a pressure plate, and a reflector mounting plate. The fixing plate R and the fixing plate L are respectively installed at both ends of the reflector mounting plate, and the reflector is mounted on the reflector mounting plate via the pressure plate. This structure is simple and the installation is secure.

[0009] Preferably, the camera laser assembly includes a second mounting connection plate, a camera mounting plate, a camera, a camera lens, a laser source tensioning component, a laser lamp, a laser source fixing plate, a laser source mounting plate, and a first mounting connection plate. The camera lens is mounted on the camera, the laser source mounting plate is mounted on the camera mounting plate, the laser source tensioning component, the laser source fixing plate, and the laser source mounting plate fix the laser lamp, and the first mounting connection plate is mounted on the camera laser assembly mounting plate. This structure can firmly lock the laser lamp, preventing the laser irradiation accuracy from being affected by loose components during the detection process. Furthermore, it has a high degree of modular integration; each component is assembled in layers via dedicated mounting plates, facilitating later maintenance and replacement of individual components.

[0010] Preferably, the loading / unloading suction head assembly includes a main beam frame of the loading arm, a camera laser component mounting plate, a suction head assembly, and a suction head. The camera laser component mounting plate is mounted on the suction head assembly, and the suction head is mounted below the suction head assembly. The suction head assembly is mounted on the main beam frame of the loading arm and can move in a translational manner. This design allows for efficient and coordinated chip loading / unloading and detection. During the translational movement of the suction head assembly, chip loading / unloading and attitude / material shortage detection can be completed simultaneously without the need to move the detection component separately, thus shortening the cycle time for each operation.

[0011] Preferably, both the laser reflection component and the camera laser component can move translationally on the main beam of the feed arm.

[0012] Preferably, the camera laser assembly includes a laser light clamp, a laser light mounting plate, a left camera mounting plate, a camera lens, a camera, a laser light, a right camera mounting plate, and a camera support. The laser light clamp and the laser light mounting plate fix the laser light. The laser light mounting plate is mounted on the left camera mounting plate. The camera lens is mounted on the camera and the right camera mounting plate. The camera support is mounted on both the right and left camera mounting plates. This structure makes the structure stable and reliable. Each functional component (laser light, camera) has its own dedicated mounting plate, allowing for individual fine-tuning of the laser angle or camera position without the need for overall disassembly.

[0013] Preferably, the laser reflecting assembly includes a left reflector bracket, a pressure plate, a reflector mounting plate, a reflector, and a right reflector bracket. The left and right reflector brackets are mounted on the reflector mounting plate, and the reflector is fixed to the reflector mounting plate by the pressure plate. The laser reflecting assembly is mounted on the suction head assembly.

[0014] Preferably, the suction head is installed below the suction head assembly, the suction head assembly is installed on the main beam of the feed arm, and the camera laser assembly mounting plate is installed on the suction head assembly.

[0015] Preferably, the camera laser assembly includes a laser lamp, and the angle between the laser lamp and the reflector is adjustable. Throughout the entire loading and unloading process, the laser lamp can illuminate the object being photographed by adjusting the reflector, thereby monitoring the chip's position status throughout the entire process.

The laser reflection component 100 and the camera laser component 200 are respectively connected to the loading / unloading suction head component 300. The camera laser component 200 captures an image of the laser emitted by the laser reflection component 100 on the object being scanned. The irradiation direction of the camera laser component 200 is movable, the direction of the laser reflected by the laser reflection component 100 is variable, and the angle between the laser emitted by the laser reflection component 100 and the camera laser component 200 is variable.

[0029] The object illuminated by the laser emitted by the laser reflection component 100 refers to the tray and / or tray scanning mechanism and / or the feeding device and / or the discharging device of the tray scanning mechanism used to hold chips. The chips held in the tray and / or the feeding device and / or the discharging device of the tray scanning mechanism may be misaligned or not at all.

[0030] The solution of this utility model can capture images of the chip's placement posture, enabling detection of the entire feeding process and avoiding omission of critical steps. It is also highly adaptable, with the camera's laser component irradiation direction movable and the laser reflection component's reflection direction changeable, meeting the detection needs of the object being photographed in different positions. The detection is accurate and efficient, quickly identifying problems such as incorrect chip placement posture or missing materials, reducing subsequent process failures.

[0031] The laser reflection component 100 is installed below the loading / unloading suction head assembly 300, and the camera laser component 200 is installed above the loading / unloading suction head assembly 300. This design is compact and efficient, with the components integrated around the loading / unloading suction head assembly, eliminating the need for a large additional installation space.

For example, when a chip is located in the preheating tray 2006, the loading area camera 003 can capture images of the chip illuminated by the loading area laser light 005 to determine its position. The loading area camera 003 captures images of the chip placement positions on the Tray tray, preheating tray 2005, preheating tray 1006, and the feeding trolley B008. The unloading area camera 016 captures images of the chip placement positions captured by the unloading trolley A011 or B012. Algorithms are used to calculate and determine the chip's position, tilt, and presence at each location.
