Description
The utility model relates to the thermocompression bonder of hot pressing welding between a kind of LCDs and the printed circuit board (PCB).
Existing thermocompression bonder has delivery board to move forward and backward, and its station has only one, and loading and unloading reach LCDs and the printed circuit board (PCB) of line being adjusted required welding in front earlier, move behind the delivery board then, carries out the hot pressing welding in the back.Also there is delivery board to swing, then can reach two stations, two stations are positioned at the two ends of delivery board, load and unload and to the line adjustment at a station, then can carry out the hot pressing welding simultaneously at another station, when loading and unloading and to the line adjustment, after the hot pressing welding is all finished, the delivery board swing, LCDs that thermocompression bonding connects and printed circuit board (PCB) are put loading and unloading and line are adjusted station from welding post, LCDs and printed circuit board (PCB) that line is adjusted are put welding post from loading and unloading and to line adjustment station, carry out the loading and unloading of next round, line adjustment and hot pressing welding, improved efficient, but in actual the use, two stations still show not enough; In addition, owing to the welding template directly is anchored on the delivery board that moves forward and backward or swing.During welding, welding pressure is all born by delivery board, causes rail plate or rolling bearing between delivery board and the base to bear whole hot pressing welding pressures, rail plate or turning cylinder are worn and torn easily, be out of shape, make the lost of life of thermocompression bonder, precision reduces.
The purpose of this utility model proposes a kind of multistation thermocompression bonder that can reach more than two stations exactly.
Another purpose of the present utility model, the welding pressure that overcomes existing thermocompression bonder exactly acts directly on the defective on the delivery board, a kind of thermocompression bonder is proposed, during the hot pressing welding, can act directly on welding pressure on the base, can reach simultaneously the accurate location of hot pressing welding again, realize accurate welding.
For achieving the above object, the technical solution of the utility model is as follows:
The utility model multistation thermocompression bonder, comprise frame, delivery board, to the line guiding mechanism, welding mechanism, drive the driving mechanism that delivery board moves, delivery board detent mechanism and electric control system, described delivery board places on the frame, can move relative to frame, be installed in display and camera gun and the drive camera gun front and back of line being adjusted the frame top of station the described line guiding mechanism is comprised, the cylinder of move left and right, described welding mechanism comprises the plumb joint and the weld cylinder of the support top that is installed in welding post, this weld cylinder drives plumb joint by solenoid control and moves up and down, a fastening base above the described frame, described delivery board is a rotating disk, this rotating disk is positioned at the top of base, a plurality of stations along the circumferential direction are set on the rotating disk equably, the base center is vertically passed in a central fastening rotating shaft vertical with this rotating disk of rotating disk, rotating shaft and by this base support, the driving mechanism that described driving delivery board moves is a motor, be installed in the frame, described motor is controlled by electric control system, drives rotating shaft and intermittently rotates, and intermittently rotates thereby drive rotating disk.
A plurality of stations on the described rotating disk, each station has a slotted eye on rotating disk, the floating installation that slotted eye relatively moves up and down is installed on each slotted eye, described floating installation has a float plate, this float plate can be floated up or down and is loaded in the slotted eye suitable with this float plate size on the rotating disk, and it is spacing by the institute of the briquetting on the position, next door at the slotted eye two ends that are separately fixed at described rotating disk, the flying height of restriction float plate, at the two ends of each piece briquetting, between described float plate and the rotating disk elastic connecting device is housed; Have on the described float plate into the gas passage, the other placement in passway hollow, protrude the sealing ring on float plate surface, the location also is housed on float plate, compress the fixture that plate is touched in welding; The center at float plate two ends is provided with the positioning seat that protrudes the float plate surface, has locating hole on the positioning seat, cooperates with the location clamping sleeve of center, welded plate two ends on the weld cylinder that is installed in thermocompression bonder, constitutes the accurate location that hot pressing is welded.
Described rotating disk along the circumferential direction is provided with a plurality of stations equably and is meant 2 or 3 or 4 or more station along the circumferential direction are set equably.
Because what delivery board adopted is the rotating disk that is rotated by motor-driven, so, as required, on rotating disk, along the circumferential direction can settle 2 or 3 or 4 or more station equably, intermittently rotate by electric control system control motor, thereby the driven by motor rotating disk intermittently rotates, and makes the station on the rotating disk forward next station to from a station, forward next station again to, realize the continuous productive process between multistation; Again because a plurality of stations of employing on rotating disk, each station has a slotted eye on rotating disk, the structure of the floating installation that slotted eye relatively moves up and down is installed on each slotted eye, when when welding, welding pressure acts on the float plate of floating installation of welding post, by the slotted eye of rotating disk, float plate is pressed onto on the base, bear whole welding pressures by base, and rotating disk only bears the elastic deformation force of a little, make the rotating shaft of corresponding rotating disk not fragile; Because the location is housed on float plate, compress the fixture that plate is touched in welding, so the welding template can be fastened on the float plate, owing to adopted on the center at float plate two ends and be provided with positioning seat, have locating hole on the positioning seat, the structure that cooperates with the location clamping sleeve of center, welded plate two ends on the weld cylinder that is installed in thermocompression bonder, so, when welding, can overcome owing to the position deviation that adopts floating installation to produce, the welding template that is fastened with float plate and plumb joint are not produced all around move, reach the accurate location of hot pressing welding, realize accurate welding.
