Detailed ways

The specific implementation of the uncovering and closing device of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to accompanying drawings 1 and 2, the cover-opening and closing device is used for closing and uncovering the lid of the chip box, including the cylinder 1 and the briquetting groove 2 fixedly arranged at the lower end of the cylinder 1, and the upper bottom plate of the briquetting groove 2 3 is fixedly connected with the cylinder 1 through fasteners, and the tank body 4 of the press block groove 2 is also fixedly connected with the upper bottom plate 3 through fasteners, and a sealing ring 5 is provided on the lower surface of the upper bottom plate 3 (see Figure 3). Two J-shaped hook claws 6 are respectively arranged on both sides of the groove body 4 of the briquetting groove 2, and the upper ends of the two hook claws 6 are provided with long grooves, which are fixed on both sides of the groove body 4 by fastening screws. The design can adjust the up and down position of the claw 6. The hook heads of the two claws 6 are arranged oppositely to the inboard of the groove body 4 . A briquetting block 7 is set in the briquetting block groove 2, and the briquetting block 7 can slide in the groove body 4. A compression spring 8 is installed between the upper base plate 3 and the briquetting block 7, and a suction cup 9 is set at the lower end of the briquetting block 7. Vacuum air circuit control realizes the vacuum degree in the platen. When the briquetting block 7 is pressed tightly on the sealing ring 5 on the upper base plate 3, the suction cup, the briquetting block, the lower surface of the upper base plate and the sealing ring form a closed space.

Referring to accompanying drawings 4 and 5, the chip box 10 includes a base 11, a chip accommodating cavity 12 provided on the base 11, and buckles 13 provided on both sides of the base 11. The inside of the buckle 13 is provided with a buckle head, and the buckle 13 The outer side is provided with an arc-shaped concave surface; the cover 14 cooperates with the chip box 10, and is used to close the chip in the accommodating cavity 12 on the chip box 10, and the cover 14 includes a slot 15 provided on both sides, and the slot 15 is connected with the buckle When the buckle 13 is turned inward, the buckle head cooperates with the slot 15 to close the cover 14 and the chip box 10. When the buckle 13 is turned outward, the buckle head is separated from the slot 14, and the lid 14 is unclamped with chip box 10, and cover 14 can be taken out. Positioning pins are arranged on the lower surface of the cover 14, and positioning holes are provided on the chip box 10. When the cover 14 is closed on the chip box 10, the positioning pins fit into the positioning holes to realize accurate closing. The lower surface of the cover 14 is provided with a plurality of blowing holes, the blowing holes are controlled by a blowing air path, and the blowing holes are drawn from the side hole 16 of the cover 14 to the blowing air path. A pressure head 17 corresponding to the chip accommodating cavity 12 is provided on the cover 14 to realize sealing and pressing of the chip in the chip accommodating cavity 12 .

The distance between the two claws 6 matches the distance between the two buckles 13. When the claws 6 move downward from the top of the buckles 13, the J-shaped head of the claws 6 squeezes the buckles 13 The arc-shaped concave surface of the chip box 10 is turned outward so that the buckle 13 is turned outward, and the cover 14 on the chip box 10 is released. When the claw 6 moves upward from the bottom of the buckle 13, the J-shaped hook head of the claw 6 pulls the arc-shaped concave surface of the buckle 13, so that the buckle 13 is turned inward, and the buckle 13 is buckled in the slot 15. The closing of the cover 14 on the chip box 10 is realized.

The working process of uncovering the cover of this device is, firstly, after moving the chip box covered with the cover to the predetermined working position of the device, the cylinder is driven to press down, and after the suction cup touches and presses the cover, the cylinder continues to press down, and at this time the compression spring is pressed Compressed by the pressure of the block, the two claws cooperate with the card and start to open the buckle, and the pressure block continues to compress the spring until the pressure block cooperates with the sealing ring on the upper bottom plate of the pressure block groove, compressing the sealing ring to elastic deformation to achieve Sealing, at this time, the upper surface of the cover, the suction cup, the pressing block, the lower surface of the upper bottom plate and the sealing ring form a closed space. At this time, the claws will fully open the buckle. At this time, the vacuum air circuit is opened, and a vacuum negative pressure is formed in the closed space, and the suction cup tightly sucks the cover, and the sealing ring is elastically deformed due to the vacuum pressure, so that the cover is no longer pressed against the cavity in the accommodating space of the chip box. There is a slight gap between the chip and the base. The vacuum pressure switch set on the base detects this signal and starts the air blowing circuit to blow off some chips that may be stuck on the cover pressure head to ensure that the chips are not damaged. will be brought out and shifted. Then the cylinder is lifted, and when the cylinder is lifted, the claw will reset the buckle, and remove the chip box to the next process.

The working process of closing the cover of this device is to move the chip to the predetermined position under the device after loading the chip box, and the cylinder absorbs the cover by vacuum pressure. The cylinder presses down with the cover, the claw first touches the buckle to open the buckle, and then continues to descend so that the pressure head of the cover touches the chip, and after further descending under the action of the cylinder, the cover and the base are completely fitted in place. Close the vacuum air circuit, and the pressure block exerts pressure on the cover under the action of the spring because there is no negative pressure support. Drive the cylinder to lift up. Due to the elastic deformation of the spring, when the hook leaves the buckle, the cover and the base are always completely attached. When the hook leaves completely, the buckle is pulled to the locked position by the hook to lock the cover. The cylinder is further lifted away, the whole device is separated from the chip and the lid is closed, and then the chip box is moved to the next process such as the test position for testing.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications should also be considered Be the protection scope of the present invention.
