Description

Technical Field

[0001] The utility model relates to the technical field of chip detection equipment, in particular to an electronic chip detection equipment. Background Art

[0002] An electronic chip, also known as an integrated circuit, is a microcircuit processed on the surface of a wafer. The function of the chip is to enable the transmission of circuit signals. It is an important electronic component that is indispensable to modern industry. Chips are usually quality inspected before leaving the factory.

[0003] The patent specification with the announcement number CN220019803U discloses an electronic chip detection device. The chip is aligned and placed in the chip slot, and the pressure plate is pressed downward. The rubber spring and the hydraulic telescopic buffer rod connected between the pressure plate and the top plate generate tension. When the fixing pin contacts the fixed base, the fixing pin moves inward along the arc surface structure at the top of the fixed base, compressing the reset spring. When the fixing pin moves to the fixed slot, the fixing pin will be reset under the rebound force of the reset spring and stuck in the fixed slot. At the same time, the pressure plate is pressed inward, and the suction plate fixes the chip. The suction plate receives The reaction force of the chip moves upward to compress the spring telescopic rod. When the chip detection is completed, the small air pump is started. The small air pump drives the cylinder to generate suction from the suction port to adsorb the chip to the bottom wall of the suction plate, and the slide buckle is pushed inward. The slide buckle drives the fixing pin to move inward and withdraw from the fixing groove. The pressure plate loses its fixing force and moves upward under the action of the rubber spring and the hydraulic telescopic buffer rod, bringing the chip upward to prevent the pins from being damaged when the chip is manually removed, reducing the probability of the chip being damaged. When the small air pump fails, the chip can also be taken out through the spare removal groove.

[0004] However, in the implementation of relevant technologies, it was found that an electronic chip detection device of the above design has the following problems: in the prior art, the chip is taken out by the cooperation of components such as rubber springs, but in actual use, the placement and removal of the chip includes processes such as pressing the pressure plate, which requires manual participation and assistance and cannot achieve an automated effect, resulting in a waste of human resources. In view of this, an electronic chip detection device is provided to overcome the above defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an electronic chip detection device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electronic chip detection device, comprising an operating table, a mounting groove is opened at the top of the operating table, a fixing block is fixed at the middle position inside the mounting groove, and a taking mechanism is arranged below the fixing block;

[0007] The taking mechanism includes a coil, which is embedded in the interior of a fixed block, and an iron core is arranged inside the coil, a permanent magnet is passed through the position of the fixed block corresponding to the iron core, and a connecting rod is fixed to one end of the permanent magnet passing through the fixed block, a carrying plate is fixed to the outer wall of the connecting rod, and a spring is sleeved under the carrying plate of the outer wall of the connecting rod, an air suction device is slidably connected above the carrying plate, and a micro push rod is arranged between the air suction device and the carrying plate, when the coil is energized, the iron core generates magnetic force and repels the permanent magnet, so that the connecting rod drives the carrying plate to move toward the chip position, and after being sucked by the air suction device, it is pushed out by the micro push rod, thereby avoiding manual auxiliary pressing operations and improving automation.

[0008] As a further description of the above technical solution: the structure of the supporting plate is a U-shaped structure, and the supporting plate forms a sliding structure through the connecting rod and the mounting groove. The U-shaped structure of the supporting plate makes it easy for the micro push rod to push the suction device and slide stably along the supporting plate to avoid shaking. The suction device is composed of conventional components such as a pump and an air nozzle.

[0009] As a further description of the above technical solution: a first limiting ring is fixed to the outer wall of the permanent magnet, and a second limiting ring is connected to the outer wall of the connecting rod. The first limiting ring allows the permanent magnet to be inside the fixed block to avoid detachment, and the second limiting ring allows the connecting rod to be located inside the operating table to avoid detachment, thereby preventing loosening and detachment, affecting the sliding of the carrier plate and thus affecting the picking and placement of the chip.

[0010] As a further description of the above technical solution: a feeding mechanism is provided on one side of the fixed block inside the installation groove, and the feeding mechanism includes a first conveying device, the first conveying device is fixed at one end of the operating table, and a second conveying device is passed through the other end of the operating table. The chip to be tested is transported into the detection range by the first conveying device, and the chip after testing is transported to the next process by the second conveying device, thereby avoiding manual picking and transportation, reducing human resources and improving detection efficiency.

[0011] As a further description of the above technical solution: the feeding mechanism also includes a loading frame, which is fixed at one end of the first conveying device inside the installation groove, and the loading frame is rotatably connected to a conveying roller inside. A limiting groove is provided at the bottom end of the installation groove corresponding to the position of the suction device, and a detection module is embedded in the limiting groove. The loading frame with an inclined structure and multiple groups of conveying rollers are convenient for receiving the chips conveyed by the first conveying device and conveying them to the limiting groove. The detection module is used for detection, thereby avoiding manual assisted placement, improving automation and thus improving detection efficiency.

[0012] As a further description of the above technical solution: The conveying rollers are evenly distributed at equal intervals with respect to the inner wall of the loading rack, and the loading rack is detachably connected to the operating table by bolts. The detachable connection of the loading rack facilitates the maintenance or replacement of internal components.

[0013] As a further description of the above technical solution: A pressure sensor is embedded at the top of the loading rack, and a PLC control terminal is installed on one side of the mounting groove at the top of the operating table. When the chip is conveyed to the loading rack and activates the pressure sensor, the first conveying device stops under the control of the PLC control terminal, thereby avoiding the situation of accumulation. Programs for the working sequence and connection of each mechanism and component are pre-compiled, so that the PLC control terminal controls the opening and closing of the coil and the opening and closing of the suction device, maintaining the automation of the detection device.

[0014] The utility model has the following beneficial effects:

[0015] In an electronic chip detection device designed by the utility model, when the chip is to be picked up after being detected, the coil is energized and the iron core has magnetic force. The magnetic poles of the contact surface between the iron core and the permanent magnet are the same, so they repel each other, pushing the connecting rod and driving the bearing plate to slide down, enabling the air nozzle of the suction device to suck the chip. Subsequently, after the coil is disconnected, under the elastic push of the spring, the bearing plate resets, and the suction device drives the chip to the next process through the telescopic movement of the micro-push rod, avoiding manual auxiliary pressing and picking, etc., and avoiding the waste of human resources, achieving automation and improving the detection efficiency.

[0016] In an electronic chip detection device designed by the utility model, when the first conveying device conveys the chip to be detected to the loading rack, the pressure sensor is triggered, and the first conveying device is closed through the PLC control terminal to avoid the continuous stacking of chips. The chip enters the limit slot through the cooperation of the loading rack and the conveying rollers, and is detected by the detection module embedded in the operating table. After the detection is completed, the picking mechanism picks up the chip and moves it above the second conveying device. Subsequently, the suction device is closed and the chip falls on the second conveying device and is conveyed to the next process, avoiding manual loading and unloading or auxiliary transfer, etc., reducing the labor intensity and the waste of human resources, and achieving automated detection to improve the detection efficiency.

[0024] Referring to Figures 1-5 , an electronic chip detection device provided by the present utility model: including an operating table 1, an installation groove 2 is opened at the top of the operating table 1, a fixed block 3 is fixed at the middle position inside the installation groove 2, and a retrieving mechanism 4 is arranged below the fixed block 3; the retrieving mechanism 4 includes a coil 401, the coil 401 is embedded inside the fixed block 3, an iron core 402 is arranged inside the coil 401, a permanent magnet 403 penetrates out at the position corresponding to the iron core 402 inside the fixed block 3, one end of the permanent magnet 403 penetrating out of the fixed block 3 is fixed with a connecting rod 404, a bearing plate 405 is fixed on the outer wall of the connecting rod 404, a spring 406 is sleeved below the bearing plate 405 on the outer wall of the connecting rod 404, a suction device 408 is slidably connected above the bearing plate 405, and a micro-push rod 407 is arranged between the suction device 408 and the bearing plate 405. After the coil 401 is energized, the iron core 402 generates magnetic force and repels the permanent magnet 403, so that the connecting rod 404 drives the bearing plate 405 to move towards the chip position, and after being sucked by the suction device 408, it is pushed out by the micro-push rod 407, avoiding manual auxiliary pressing operations and improving automation.

[0025] As a further implementation of the above technical solution: the structure of the bearing plate 405 is a U-shaped structure, the bearing plate 405 forms a sliding structure with the installation groove 2 through the connecting rod 404. The U-shaped structure of the bearing plate 405 facilitates the micro-push rod 407 to push the suction device 408 to slide stably along the bearing plate 405, avoiding shaking. The suction device 408 is composed of conventional components such as a pump and a nozzle.

[0026] As a further implementation of the above technical solution: A first limiting ring 5 is fixed to the outer wall of the permanent magnet 403, and a second limiting ring 6 is connected to the outer wall of the connecting rod 404. The permanent magnet 403 is kept inside the fixed block 3 by the first limiting ring 5 to prevent it from detaching. The connecting rod 404 is located inside the operating table 1 by the second limiting ring 6 to prevent it from detaching, thus preventing loosening and detachment, which may affect the sliding of the bearing plate 405 and thus affect the picking and placing of the chip.

[0027] During specific implementation, when the chip needs to be picked up after detection, the coil 401 is energized to make the iron core 402 generate magnetic force, thereby repelling the permanent magnet 403 and causing the connecting rod 404 to drive the bearing plate 405 to move downward. The nozzle of the suction device 408 sucks the chip. Subsequently, the coil 401 is de-energized, and the connecting rod 404 drives the bearing plate 405 to reset by the elastic push of the spring 406, so that the suction device 408 resets. Then, driven by the micro-push rod 407, the suction device 408 drives the chip out of the range of the fixed block 3 and transports it to the next process.

[0028] As a further implementation of the above technical solution: A feeding mechanism 7 is provided on one side of the fixed block 3 inside the installation groove 2. The feeding mechanism 7 includes a first conveying device 701, which is fixed at one end of the operating table 1. The other end of the operating table 1 is provided with a second conveying device 702 passing through. The chips to be detected are conveyed into the detection range by the first conveying device 701, and the detected chips are conveyed to the next process by the second conveying device 702, avoiding manual picking and transfer, reducing human resources and improving the detection efficiency at the same time.

[0029] As a further implementation of the above technical solution: The feeding mechanism 7 further includes a loading rack 703, which is fixed at one end of the first conveying device 701 inside the installation groove 2. A conveying roller 704 is rotatably connected inside the loading rack 703. A limiting groove 705 is opened at the bottom end inside the installation groove 2 corresponding to the position of the suction device 408, and a detection module 706 is embedded in the limiting groove 705. The inclined loading rack 703 and multiple groups of conveying rollers 704 facilitate receiving the chips conveyed by the first conveying device 701 and conveying them into the limiting groove 705 for detection by the detection module 706, avoiding manual assisted placement, improving automation and thus improving the detection efficiency.

[0030] As a further implementation of the above technical solution: The conveying rollers 704 are evenly distributed at equal intervals on the inner wall of the loading rack 703. The loading rack 703 is detachably connected to the operating table 1 by bolts. The detachable connection of the loading rack 703 facilitates the maintenance or replacement of the internal components.

[0031] As a further implementation of the above technical solution: a pressure sensor 8 is embedded at the top of the loading rack 703, and a PLC control terminal 9 is installed on one side of the installation groove 2 at the top of the operating table 1. When the chip is transported to the loading rack 703 and activates the pressure sensor 8, the first conveying device 701 stops under the control of the PLC control terminal 9, thus avoiding the situation of accumulation. Programs for the working sequence and connection of each mechanism and component are pre-compiled, so that the PLC control terminal 9 controls the opening and closing of the coil 401 and the opening and closing of the suction device 408, maintaining the automation of the detection device.

[0032] During specific implementation, the chip is transported to the loading rack 703 by the first conveying device 701. After the signal is sensed by the pressure sensor 8, it is transported to the PLC control terminal 9 for control, and the first conveying device 701 stops. The conveying roller 704 and the adapted micro motor assembled on the loading rack 703 then push the chip into the limit slot 705 for detection by the detection module 706. After the detection is completed, the chip is sucked by the suction device 408. Under the push of the micro push rod 407, when it reaches above the second conveying device 702, the suction device 408 closes and the chip drops. The chip is transported by the second conveying device 702 to the next process. If it is in an unqualified state, the buzzer equipped with the PLC control terminal 9 will remind the staff to pay attention. After the chip drops, all mechanisms and components are shut down to facilitate the staff to pick up the unqualified chips.
