[0050] Internal through grooves 9 that slidably cooperate with the bracket 66 are provided on both sides of the center of the work station 2, the outer cover 3 and the inner cover 4, which play a role of sliding limit for the bracket 66 and the sliding member 68, thereby improving the displacement stability of the bracket 66 and the sliding member 68, and external through grooves 10 are provided diagonally on both sides of the work station 2, the outer cover 3 and the inner cover 4. A single track 11 is fixedly connected to one side of the work station 2 close to the internal through groove 9 and the external through groove 10, and a guide block 12 that is fixedly cooperated with the support 67 is slidably connected to the single track 11, which plays a role of sliding support for the support 67 and also prevents the support 67 from shaking and tilting during displacement. A grating sensor 17 is fixedly connected to one side of the support 67 close to the guide block 12 to monitor the displacement stroke of the support 67 in real time.

[0051] The joint assembly 7 includes a joint frame 71 fixed on the support 67, and an anti-detachment cover plate 72 is fixed on the top of the joint frame 71 by screws. The anti-detachment cover plates 72 on the two sets of joint frames 71 play an anti-detachment role on the chip frame. One side of the back of the joint frame 71 is fixedly connected to a drive motor 73, and the two sides of the joint frame 71 facing each other are rotatably connected to synchronous rollers 74, one of which is fixedly connected to the output shaft of the drive motor 73.

The electrostatic dust removal rollers 225 are sleeved with sticky dust rolls 226. The sticky dust rolls 226 sleeved on the several electrostatic dust removal rollers 225 are used to perform rolling electrostatic dust removal operations on the bottom of the chip frame transported on the two synchronous belts 78, thereby improving the cleanliness of the chip frame during transportation to prevent tiny floating dust particles from affecting the subsequent processing of the chip frame.

[0053] 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 a wind pressure assembly 8 used in conjunction with the joint assembly 7, and the wind 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 slidably cooperates with the cylinder barrel 5. The two sets of sliding members 68 that reciprocate inside and outside drive the piston seats 83 on the two piston rods 82 through the two sets of angle plates 81 to perform reciprocating work in the two diagonally distributed cylinder barrels 5, and provide a supply of pressurized air source;

[0054] The exhaust pipe 13 is connected with a telescopic pipe 84, and the other end of the telescopic pipe 84 is connected with a pressurizing pipe 85 that is slidably matched with the outer through groove 10, and the bottom end of the pressurizing pipe 85 is connected with a wind pressure cover 86 that is fixedly matched with the anti-detachment cover plate 72, and the bottom array of the wind pressure cover 86 is provided with a wind pressure grid slot 87, and the bottom of the wind pressure grid slot 87 is fixedly connected with a flow equalizing plate 88, and the anti-detachment cover plate 72 is provided with a wind pressure opening area that is connected and matched with the wind pressure grid slot 87 and the flow equalizing plate 88. The boosted air source generated in the two groups of cylinder barrels 5 passes through two rows. The telescopic tube 84 and the pressurizing tube 85 on the air pipe 13 are supplied to two groups of wind pressure covers 86, and then divided into zones and equalized flows by two groups of wind pressure grid slots 87 and flow equalizing plates 88, and then pass through the wind pressure opening area on the anti-detachment cover plate 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 to prevent the synchronous belts 78 from idling on the chip frames, causing the chip frame conveying delays, and at the same time, the fine floating dust particles attached to the chip frames are also blown away and cleaned.

[0055] The exhaust port of the cylinder barrel 5 is connected to an exhaust pipe 13, and an exhaust valve is provided on the exhaust pipe 13. The air intake port of the cylinder barrel 5 is connected to an air intake pipe 14, and an air intake valve is provided on the air intake pipe 14 to meet the exhaust and supply work requirements of the piston rod 82 in the cylinder barrel 5. An air intake cavity is opened in the air intake port of the air intake pipe 14, and an annular groove is opened in the air intake cavity, and a filter plate 15 used in conjunction with the cylinder barrel 5 is clamped in the annular groove to filter the air sucked into the cylinder barrel 5. Intake channel openings 16 used in conjunction with the intake pipe 14 are diagonally opened on both sides of the outer cover 3, and a filter hole plate is embedded in the air intake channel opening 16 to pre-filter the air passing through the outer cover 3 and entering the cylinder barrel 5, thereby improving the cleanliness of the air sucked into the cylinder barrel 5 to avoid contaminating the chip frame.

[0056] A chip frame conveying device has a working principle: 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 groups of screw sleeves 65 to reciprocate inside and outside, and the two groups of screw sleeves 65 drive two groups of brackets 66 and sliding members 68 to slide and displace in the two groups of inner through grooves 9 accordingly, and the two groups of single rails 11 and guide rail blocks 12 provide sliding support for the two groups of supports 67, and then the two groups of brackets 66 drive the two groups of supports 67 to move synchronously inwards, and the two groups of grating sensors 17 monitor the travel of the two groups of supports 67 that move synchronously inwards in real time, so as to prepare for the joint work of the chip frame;

[0057] When the two groups of supports 67 drive the two groups of joint frames 71 to synchronously reach the joint position inward, the two groups of anti-detachment cover plates 72 first perform anti-detachment treatment on the chip frames before and after the two groups of joint frames 71, and synchronously control the two groups of drive motors 73 to start, 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, and then the two groups of forward and reverse rotating drive motors 73 drive the two groups of synchronous rollers 74 to rotate, and the two groups of limiting wheels 75, guide wheels 76 and tensioning wheels 77 guide and tension the synchronous belts 78 in turn. Under the cooperation of transmission, the two groups of synchronous rollers 74 drive the two synchronous belts 78 to transmit in opposite directions, and the position The synchronous belt 78 in the joint frame 71 at the loading position drives the chip frame forward to the synchronous belt 78 in another set of joint frames 71, and the synchronous belt 78 in the other set of joint frames 71 transports the chip frame with the completed joint backward to the predetermined position. At this time, 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 frame 71 at the loading position is reset to the initial loading position. The chip frame in the joint frame 71 with the completed joint is transported backward to the next station, and then the grabbing arm 20 moves the transported chip frame to the stamping mechanism 21 for stamping and demoulding operation. By analogy, the chip frame can be continuously transported in both directions.

[0058] At the same time, two groups of diagonally distributed micro electrostatic generators 224 are controlled to be turned on. Since two groups 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 groups of connector frames 71 and the overall frame 1, the two groups of micro electrostatic generators 224 and two groups of conductive blocks 223 on the two groups of mounting frames 222 provide static electricity supply to the plurality of electrostatic dust removal rollers 225, so that the plurality of electrostatic dust removal rollers 225 carry static adsorption force and pass through the sticky roll paper 226 sleeved on the plurality of electrostatic dust removal rollers 225 to perform rolling electrostatic dust removal operation on the lower surface of the chip frame transported on the two synchronous belts 78, and with the help of the plurality of electrostatic dust removal rollers 225, the chip frame is also played with the role of auxiliary rolling transportation;

[0059] 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 negative pressure suction of the two sets of piston seats 83, the external air is filtered in advance by the filter holes in the two sets of diagonally distributed intake channel openings 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 sucked into the two groups of cylinder barrels 5 is pressurized and discharged from the two exhaust pipes 13 to the two telescopic tubes 84 following the reciprocating telescopic action 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 gas source is supplied to the two groups of wind pressure covers 86 through the two pressurized pipes 85 in the two diagonally distributed external through grooves 10, and after being zoned and equalized by the two groups of wind pressure grid grooves 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-like 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.
