[0002] Integrated circuit, abbreviated as IC; also known as microcircuit, microchip, wafer / chip in electronics is a way to miniaturize circuits (mainly including semiconductor devices, but also passive components, etc.), and is often manufactured on the surface of semiconductor wafers. During chip processing, a chip frame is required as a carrier of the chip. When the chip die is installed, the chip frame needs to be transported to the workbench for a series of processing procedures.

[0003] In the prior art (patent application with publication number CN213752656U, entitled "A Chip Frame Conveying Structure"), the chip frame is conveyed by a conveying block, and then a cylinder is activated to position a limiting rod within a limiting hole, thereby positioning a negative pressure suction cup in the middle of the chip frame. This further increases the precision of the negative pressure suction cup and the chip frame. The servo motor and cylinder are then activated to convey the chip frame to the workbench. The limiting rod effectively prevents the chip frame from colliding with the workbench and causing damage to the chip frame.

[0031] like Figure 14-16 As shown, during the bidirectional docking and transportation of the chip frame, since the chip frame is in a light-weight thin sheet state, transportation delay is prone to occur, resulting in the chip frame not being properly docked, affecting its transportation work. The cylinder barrel 5 is provided with an air pressure assembly 8 used in conjunction with the joint assembly 7, and the air pressure assembly 8 includes an angle plate 81 diagonally fixed to the bottom of the sliding member 68, the inner side of the angle plate 81 is fixedly connected to a piston rod 82, and the other end of the piston rod 82 is fixedly connected to a piston seat 83 that slides with the cylinder barrel 5.

[0033] The working principle of a chip frame conveying device is as follows: first, the chip frame is loaded to the predetermined position on the two synchronous belts 78 in the joint frame 71 located at the loading position through the loading mechanism 18, and then the glue gun on the glue dispensing mechanism 19 performs glue dispensing operation on the tiny components of the chip frame. After completing the preparation work before the chip frame is conveyed, the servo motor 61 is controlled to start and drive the main bevel gear 62 to rotate, and the main bevel gear 62 drives the forward and reverse reciprocating screw 64 on the slave bevel gear 63 to rotate accordingly, and the forward and reverse reciprocating screw 64 drives two sets of screw sleeves 65 to reciprocate inside and outside, and the two sets of screw sleeves 65 drive two sets of brackets 66 and sliding members 68 to slide in the two sets of inner grooves 9. Under the sliding support cooperation of the two sets of single rails 11 and the guide rail blocks 12 for the two sets of supports 67, the two sets of brackets 66 drive the two sets of supports 67 to move synchronously inwards. During this period, the two sets of grating sensors 17 monitor the travel of the two sets of supports 67 that move synchronously inwards in real time, preparing for the joint work of the chip frame; When the two sets of supports 67 drive the two sets of joint frames 71 to arrive at the joint position synchronously inwardly, the two sets of anti-slip cover plates 72 are used to prevent the chip frames on the two sets of joint frames 71 from slipping off, and the two sets of drive motors 73 are turned on synchronously, and the drive motor 73 on the joint frame 71 at the loading position rotates forward, and the drive motor 73 on the joint frame 71 on the other side rotates reversely. Then, the two sets of forward and reverse rotating drive motors 73 drive the two sets of synchronous rollers 74 to rotate, and the two sets of limiting wheels 75, guide wheels 76 and tensioning wheels 77 guide and tension the synchronous belts 78 in turn. Under the cooperation of the transmission, the two sets of synchronous rollers 74 drive the two synchronous belts 78 to transmit in opposite directions, and the position At the loading position, the synchronous belt 78 in the joint rack 71 drives the chip frame forward to be transported to the synchronous belt 78 in another set of joint racks 71. After the synchronous belt 78 in the other set of joint racks 71 transports the chip frame with the completed joint backward to the predetermined position, the forward and reverse reciprocating screw rods 64 drive the two sets of screw rod sleeves 65 to move outward synchronously, and the empty joint rack 71 at the loading position is reset to the initial loading position. The chip frame in the joint rack 71 with the completed joint is transported backward to the next station, and then the grabbing arm 20 moves the chip frame after being transported to the stamping mechanism 21 for stamping and demoulding operation. By analogy, the chip frame can be continuously transported in both directions. At the same time, the two diagonally distributed micro electrostatic generators 224 are controlled to be turned on. Since the two sets of insulating seats 221 insulate and fix the mounting frame 222 and the connector frame 71 to prevent static electricity from being transmitted to the two sets of connector frames 71 and the entire frame 1, the two sets of micro electrostatic generators 224 and the two sets of conductive blocks 223 on the two sets of mounting frames 222 provide static electricity to the multiple electrostatic dust removal rollers 225. After the multiple electrostatic dust removal rollers 225 carry electrostatic adsorption force, they pass through the sticky dust rolls 226 sleeved on the multiple electrostatic dust removal rollers 225 to perform rolling electrostatic dust removal on the lower surface of the chip frame conveyed on the two synchronous belts 78. With the help of the multiple electrostatic dust removal rollers 225, the chip frame is also assisted in rolling conveying. During this period, the two sets of sliding members 68 that move back and forth inside and outside drive the piston seats 83 on the two piston rods 82 to perform reciprocating work in the two sets of cylinder barrels 5 through the two sets of angle plates 81. When the two sets of piston seats 83 are in the return suction state in the two sets of cylinder barrels 5, the exhaust valves on the two exhaust pipes 13 are controlled to be closed, and the suction valves on the two suction pipes 14 are opened. Under the action of the negative pressure suction of the two sets of piston seats 83, the outside air is pre-filtered by the filter plates in the two sets of diagonally distributed intake channel ports 16 before reaching the outer cover 3, and then filtered for the second time by the filter plate 15 in the suction cavity before reaching the two sets of cylinder barrels 5, completing the return suction work. When the two sets of piston seats 83 are in the process exhaust state in the two sets of cylinder barrels 5, on the contrary, the exhaust valves on the two exhaust pipes 13 are controlled to be closed. When the valve is opened and the intake valves on the two intake pipes 14 are closed, the pure gas inhaled in the two groups of cylinder barrels 5 is pressurized and discharged from the two exhaust pipes 13 to the two telescopic pipes 84 following the reciprocating telescopic movement of the two groups of anti-detachment cover plates 72 under the extrusion pressure of the two groups of piston seats 83, and then the pressurized air source is supplied to the two groups of wind pressure covers 86 through the two pressurized pipes 85 in the two diagonally distributed external grooves 10, and after being partitioned and equalized by the two groups of wind pressure grid slots 87 and the flow equalizing plates 88, it passes through the wind pressure opening areas on the two groups of anti-detachment cover plates 72 to reach the chip frames in the conveying state in the two groups of joint frames 71, so that the thin-sheet chip frames are always attached to the two transmission state synchronous belts 78, and at the same time, the fine floating dust particles attached to the upper surface of the chip frames are also blown clean.
