Description

Technical Field

[0001] The utility model relates to the technical field of chip processing, in particular to a chip grabbing structure. Background Art

[0002] With the continuous development of science and technology, the application of chips in electronic devices is becoming more and more extensive. In the production, testing, maintenance and other links, an efficient and accurate chip grasping structure is needed to realize fast and stable grasping and placement of chips. Among them, the "a chip grasping structure and chip processing equipment" disclosed by the announcement number "CN213976048U" has solved the various disadvantages that the grasping methods of the current devices are all single and do not have the ability to change the clamping method according to the situation, which is not convenient for chip production. After further searching, it was found that the "an automatic grasping structure for chip production" disclosed by the announcement number "CN210073805U" has effectively solved the traditional The grasping structure clamps the chip placed inside the chip box by moving the clamping claws, which makes it difficult to place the chip box and has technical disadvantages such as low efficiency. However, in actual use, chip grasping structures with similar structures still have many defects, such as: there is no better protective structure. During the grasping process, it is easy for the chip to fall due to loose grasping, which makes it inconvenient to protect the chip from falling, reducing the safety effect. At the same time, it is generally grasped by suction through a suction cup. Since the suction cup is made of rubber, it is easily affected by the external environment and aged after use, which will cause warping at the edges, resulting in gaps when fitting with the chip, and loose adsorption is easy to occur. Therefore, it is necessary to design a chip grasping structure. Utility Model Content

[0003] The purpose of the utility model is to provide a chip grabbing structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chip grabbing structure, comprising a mounting plate, a fixing plate and a fixing frame, the bottom of the mounting plate is fixedly mounted with a fixing plate, the bottom of the fixing plate is fixedly connected with a fixing frame, a movable frame is slidably mounted at the front and rear ends of the fixing frame, a tray is fixedly mounted at the bottom of the movable frame, a movable frame is slidably mounted on one side of the fixed frame, a mounting plate is fixedly mounted at the bottom of the movable frame, a suction cup is fixedly mounted at the bottom of the mounting plate, and a pressure ring is movably mounted at the bottom of the mounting plate outside the suction cup.

[0005] When the movable frame moves downward, the movable frame can be used to drive the tray to flip upward, which will not affect the adsorption and grabbing operation of the suction cup and the chip. The edge of the suction cup is pressed by pushing the pressure ring to prevent the edge of the suction cup from warping, thereby avoiding the situation where a gap between the suction cup and the chip leads to loose adsorption. The movable frame is driven to move upward, and the movable frame can be used to drive the tray to flip downward, so that the tray is at the bottom of the suction cup, which can facilitate the protection of the chip. Even if the chip falls, it will fall onto the tray, which can effectively protect the chip from falling to the ground and causing damage.

[0006] Preferably, the surface of the mounting plate is provided with mounting holes, and the mounting plate and the fixing plate are fixedly mounted via a connecting seat. The mounting holes can be conveniently used to fix the mounting plate to a suitable position on the mechanical arm using bolts, and the connecting seat can be conveniently connected and fixed to the fixing plate.

[0007] Preferably, the fixed frame and the movable frame are slidably mounted via a slider, and a slide groove cooperating with the slider is provided on one side of the movable frame, so that the slider slides along the slide groove, thereby ensuring the stability of the movable frame when it moves.

[0008] Preferably, the movable frame and the fixed frame are slidably mounted via sliding piles, and the front and rear ends of the fixed frame are provided with movable grooves that cooperate with the sliding piles. When the movable frame is flipped, the sliding piles can be used to rotate and slide in the movable grooves, thereby overcoming the motion interference caused by the flipping of the movable frame.

[0009] Preferably, the movable frame and the moving frame are movably mounted via a movable shaft, and a protective pad is attached to the top of the tray. When the movable frame can be moved up and down by the movable shaft, the movable frame can be driven to flip, and the protective pad can buffer and protect the dropped chips, thereby preventing the chips from being damaged by hard contact with the tray when they fall.

[0010] Preferably, a limit seat is fixedly installed on one side of the mobile frame, and an electric push rod is fixedly connected between the limit seat and the fixed plate. The mobile frame can be pushed to move up and down by the telescopic activity of the electric push rod.

[0011] Preferably, the mounting plate and the pressure ring are movably mounted via a telescopic frame, and a thrust spring is sleeved on the outer side of the telescopic frame. When the suction cup contacts the chip, the pressure ring can be moved up and down by the telescopic frame, and the thrust of the thrust spring can push the pressure ring to press the edge of the suction cup.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up the cooperation between the moving frame, the active frame and the tray, when the moving frame moves downward, the active frame can be used to drive the tray to flip upward, which can not affect the adsorption and grabbing operation of the suction cup and the chip. After grabbing the chip, the moving frame moves upward, and the active frame can be used to drive the tray to flip downward, so that the tray is at the bottom of the suction cup, which can facilitate the protection of the chip. Even if the chip falls, it will fall onto the tray, which can effectively protect the chip from falling to the ground and causing damage.

[0014] 2. By providing the cooperation between the pressure ring and the telescopic frame, when the suction cup adsorbs the chip, the edge of the suction cup can be pressed conveniently through the pressure ring, which can prevent the edge of the suction cup from warping, avoid the gap between the suction cup and the chip resulting in loose adsorption, and improve the efficiency of chip grabbing.
