[0005] As a further improvement of the present invention, in order to solve the problem that traditional transfer devices can only move in a straight line and cannot accurately position different loading positions, and to improve the flexibility and positioning accuracy of chip transfer, the chip transfer device includes a mounting block, a slider, a connecting component, a drive motor assembly, and a suction cup; the mounting block is fixedly mounted on the equipment housing, the slider is located at the upper end of the mounting block, and the connecting component is mounted on the slider; the drive motor assembly is located on the connecting component and is connected to the slider; the suction cup is located at the lower end of the connecting component, and the slider slides horizontally on the mounting block, driving the suction cup to accurately move above the chip loading device to pick up the chip and transfer the chip to the chip placement slot of the detection rotating platform.

Each of the third and fourth connecting blocks is provided with a first slide rail and a third slide rail, which are parallel to each other. A tray gripping mechanism is provided on both the first and third slide rails, and the tray gripping mechanism can move horizontally on the first and third slide rails.

[0008] As a further improvement of the present invention, in order to enable the material tray to be adjusted in height and angle during the handling process, ensuring adaptation to different workstation angles and improving the accuracy of material tray placement, the material tray gripping mechanism includes a stabilizing mounting block. One end of the stabilizing mounting block is connected to a first connecting side plate. Both the stabilizing mounting block and the first connecting side plate are provided with mounting sliders, which are connected to a first slide rail and a third slide rail. The other end of the stabilizing mounting block is provided with multiple vertical guide rails, on which a second connecting side plate is clamped. The stabilizing mounting block is also provided with a servo motor, which drives the second connecting side plate to move up and down on the vertical guide rails.

Multiple connecting vertical rods are provided between the second connecting side plate and the vacuum suction cup assembly. The second connecting side plate is driven by the servo motor to move the vacuum suction cup assembly up and down to different heights. The vacuum suction cup assembly can be rotated by the rotary cylinder assembly, causing the material tray to rotate synchronously, facilitating accurate placement of the material tray at the designated position.

[0009] As a further improvement of the present invention, in order to realize automatic replenishment and quantity management of empty trays and ensure the continuity of the sorting process, the tray supply device includes a base plate, on which a vertical mounting connecting plate is provided; multiple tray support guide rails are arranged in parallel on the vertical mounting connecting plate, and tray supports are clamped on the tray support guide rails; a driving component is also provided on the base plate, and the tray supports can move up and down on the tray support guide rails through the driving component; a lower limit block is provided at the bottom end of the tray support guide rails to limit the lowest position of the tray supports; multiple sensors are also provided on the side end of the vertical mounting connecting plate, and the number of trays is detected by the sensors.

[0010] One beneficial effect of this invention is that: by using a dual-sided synchronous detection system, combined with corresponding detection devices on the upper and lower surfaces and a dual-camera structure that slides in opposite directions, comprehensive defect identification of the upper and lower surfaces of the chip is achieved, completely eliminating the risk of missed detection; the automated tray supply and transfer system monitors the number of trays in real time through sensors, and, in conjunction with a servo motor-driven precision positioning mechanism, achieves unmanned operation of automatic supply of empty trays and classification and transfer of full trays, significantly reducing manual intervention; the high-precision tray transfer device utilizes multi-layer slide rails and a tray gripping mechanism with a rotating function, and achieves precise transfer and attitude adjustment of trays between multiple workstations through a servo motor and a rotary cylinder assembly; the gripping robot automatically sorts chips to corresponding trays according to the detection results, and the entire process is integrated and scheduled by the control system, realizing unmanned operation from chip loading to sorting completion, significantly improving production efficiency, detection accuracy and equipment compatibility, effectively reducing labor costs and ensuring product quality.

[0011] As a further improvement of the present invention, in order to achieve efficient and accurate operation of chip detection and sorting, the present invention also provides a process for a chip detection and sorting device for an oven intelligent timer. The process is designed with full automation and includes the following steps: Step 1: Chip loading. The internal lifting mechanism of the chip loading device is activated, and the electric push rod assembly on its base plate pushes the connecting plate upward to lift the chip. The limiting block at the end of the connecting rod restricts the movement distance, so that the chips are exposed in sequence at the loading position, waiting for transplanting. Step 2: Chip transfer. The chip transfer device uses the slider on the mounting block and the connecting component to drive the slider to slide horizontally through the drive motor component, which moves the suction cup to the top of the chip loading device to pick up the chip and then transfer it to the chip placement slot of the detection rotating platform. Step 3: Chip Inspection. The rotating inspection platform rotates, causing the chip to pass sequentially through the upper chip surface defect inspection device and the lower chip surface defect inspection device. The first and second drive motors of the upper chip surface defect inspection device drive the first and second vertical plates to slide opposite each other on the horizontal guide rail connecting the vertical plates, causing the first and second inspection cameras to move synchronously and perform multi-angle inspection of the upper chip surface. The lower chip surface defect inspection device performs synchronous inspection of the lower chip surface through the inspection holes, completing omnidirectional defect identification. Step 4: Empty tray supply and transfer. The drive component of the tray supply device drives the tray support to move up and down on the tray support guide rail on the vertical mounting plate of the base plate. The sensor detects the number of trays and supplies empty trays to the sorting rotary platform. The tray gripping mechanism of the tray transfer device moves horizontally on the first, second, and third slide rails through the mounting slider. The servo motor drives the second connecting side plate to move up and down on the vertical guide rail of the stable mounting block, so that the vacuum suction cup assembly reaches the target tray position and transfers the empty trays to the tray placement slot of the sorting rotary platform in sequence. Step 5: Chip sorting and transfer. Based on the test results, the gripping robot picks up qualified chips and places them onto the empty trays in the corresponding tray placement slots of the qualified chip tray placement station on the sorting rotating platform. Unqualified chips are picked up onto the empty trays in the corresponding tray placement slots of the unqualified chip tray placement station. Then, the rotating cylinder assembly drives the vacuum suction cup assembly to rotate and transfer the trays filled with chips from the sorting rotating platform to the corresponding unqualified chip tray placement station or qualified chip tray placement station, completing the entire process of testing and sorting chips for the oven's intelligent timer.

[0012] Another beneficial effect of this invention is that: in the chip loading stage, the coordinated action of the electric push rod assembly and the limiting block of the upper mechanism achieves the sequential and stable exposure of chips, avoiding the lag and error of manual replenishment, and laying the foundation for subsequent transfer; in the chip transfer stage, a combined motion mechanism of slider drive and rotary assembly is adopted to ensure accurate transfer of chips to the inspection station, improving transfer efficiency and positioning accuracy; in the chip inspection step, a double-sided synchronous inspection system is used to take multi-angle pictures of the upper and lower surfaces of the chip using opposing sliding dual inspection cameras, combined with the inspection hole design to achieve all-round defect identification, improving inspection efficiency; in the empty tray supply and transfer step, a tray gripping mechanism driven by sensors and servo motors is used to achieve automatic supply of empty trays and accurate classification and storage of full trays; finally, in the chip sorting step, relying on the coordination of the gripping robot and the rotary cylinder assembly, qualified and unqualified products are placed into the corresponding trays according to the inspection results, and automated unloading is completed by the tray transfer device. The entire process forms a closed-loop control, which significantly reduces the need for manual intervention and the risk of product omission while improving production efficiency.

[0013] In operation, the present invention firstly involves the upper lifting mechanism inside the chip loading device pushing the connecting plate upwards to lift the chip via an electric push rod assembly. A limiting block at the end of the connecting rod restricts the movement distance, exposing the chips sequentially to the loading position. Subsequently, the chip transfer device utilizes a slider on the mounting block in cooperation with the connecting assembly. A drive motor assembly drives the slider to slide horizontally, while the connecting assembly moves a suction cup above the loading device to pick up the chip, which is then transferred to the chip placement slot on the rotating inspection platform. Next, the rotating inspection platform rotates, causing the chip to pass sequentially through the upper chip surface defect detection device and the lower chip surface defect detection device. The first and second drive motors of the upper chip surface defect detection device drive the first and second vertical plates to slide opposite each other on the transverse guide rail connecting the vertical plates, causing the first and second inspection cameras to move synchronously, performing multi-angle inspection of the chip surface. The lower chip surface defect detection device performs synchronous inspection of the chip surface through inspection holes, completing omnidirectional defect identification. Then, the material tray is supplied... The device's drive assembly moves the tray support up and down on the tray support guide rail on the vertical mounting plate of the base plate. Sensors detect the number of trays and supply empty trays to the sorting rotary platform. The tray gripping mechanism of the tray transfer device moves horizontally on the first, second, and third slide rails via a mounting slider. A servo motor drives the second connecting side plate up and down on the vertical guide rail of the stable mounting block, allowing the vacuum suction cup assembly to reach the target tray position and sequentially transfer the empty trays to the tray placement slots of the sorting rotary platform. Finally, based on the detection results, the gripping robot grabs qualified chips onto the empty trays in the tray placement slots corresponding to the qualified chip tray placement positions on the sorting rotary platform, and grabs unqualified chips onto the empty trays in the tray placement slots corresponding to the unqualified chip tray placement positions. The rotary cylinder assembly drives the vacuum suction cup assembly to rotate and transfer the chip-filled trays from the sorting rotary platform to the corresponding unqualified chip tray placement positions or qualified chip tray placement positions, completing the entire process of detecting and sorting chips for the oven's intelligent timer.
