Referring to Fig. 2, Fig. 2 is the structural representation of bonding wire wire-sending device 1 in the present embodiment.Bonding wire wire-sending device 1 includes material Disk 11, Wire Wheel group, detection wheel 15, guide wheel 16, one-way wheel 20, drive mechanism 30, scaling powder adding trough 40, cutting knife 50 and machine Tool hand 60.Bonding wire 10, charging tray 11 and a controlled motor are wound with charging tray 11（It is invisible in figure）Connection, controlled motor can be controlled The rotation of charging tray processed 11 is so as to realizing the line sending of bonding wire 10.Wire Wheel group includes roller 12,13 and 14, and roller 12,13 and 14 are equal Can rotate freely around central shaft.

Referring to Fig. 3, Fig. 3 is the structure chart of Wire Wheel group in the present embodiment.Roller 12 and roller 13 are fixedly mounted on upper end On support 172, roller 14 is arranged on slide block 141, and slide block 141 is set on pillar 146 and 147, and slide block 141 can be along pillar 146 and 147 freely up and down slide.The back side of slide block 141 is installed with L-type baffle plate 142, and the side wall of L-type baffle plate 142 can be from Pass through in the groove of sensor 143,144 and 145.Sensor 143,144 and 145 is arranged on support 17, sensor 143,144 Can move up and down along the mounting groove 171 of support 17 with 145, and as needed installed in the differing heights position of support 17.

Referring to Fig. 4, it is originally the structure chart that wheel is detected in embodiment that Fig. 4 is.Detection wheel 15 includes U-bracket 152, support 152 are fixed on stage body 5 by bottom through-hole 155.Code-disc 151 is fixedly mounted on one end of rotating shaft 154, and sensor 153 is installed In one end of support 152, the peripheral edge of code-disc 151 is along in the groove of sensor 153.

Describe the operation principle of the bonding wire wire agency of the present embodiment in detail with reference to Fig. 2, Fig. 3 and Fig. 4.

As shown by the arrows in Figure 2, pile warp roller 12 is descending after bonding wire 10 is drawn from charging tray 11, bypasses on after roller 14 OK, then pass around it is descending after roller 13, it is up after detection wheel 15 further around crossing, after guide wheel 16 level to the right, through unidirectional Pass through from scaling powder adding trough 40 after wheel 20, stretch out a segment distance to the right after the opening 51 of cutting knife 50.

The front end of manipulator 60 is provided with fixture 61, and fixture 61 is clamped behind one end of bonding wire 10, and move right a segment distance, with This simultaneously, drive mechanism 30 drives one-way wheel 20 and scaling powder adding trough 40 to be moved to the left a segment distance simultaneously, when the quilt of bonding wire 10 After pulling out default length, cutting knife 50 cuts off bonding wire 10, and manipulator 60 counterclockwise overturns, and will be clipped in the weldering on fixture 61 Line is transferred on the photovoltaic battery panel on the position of welder 2, and multiple photovoltaic battery panels link together after welding, is formed such as Product shown in Fig. 6.Meanwhile, drive mechanism 30 drive one-way wheel 20 and scaling powder adding trough 40 move right jointly one section away from From so that bonding wire 10 stretches out to the right a segment distance from the opening 51 of cutting knife 50.Therefore, fixture 61 can directly clamp what is stretched Bonding wire 10, without extending in opening 51, it is very big that opening 51 need not be opened.

One-way wheel 20 is pressed in bonding wire 10 on the end upper surface of scaling powder adding trough 40, plane of the one-way wheel 20 in diagram On can only counterclockwise rotates, when being rotated clockwise one-way wheel 20, one-way wheel 20 is automatically stuck, and fixture 61 draws to the right weldering During line 10, bonding wire 10 drives the rotate counterclockwise of one-way wheel 20；After cutting knife 50 cuts off bonding wire 10, in the pulling force effect of roller 14 Under, bonding wire 10 has the trend of retraction, but one-way wheel 20 can only rotate counterclockwise, bonding wire 10 must drive unidirectional when retraction Wheel 20 turns clockwise, and one-way wheel 20 is automatically locked when turning clockwise, therefore, after cut-out bonding wire 10, bonding wire 10 will not bounce back.

When bonding wire 10 is pulled to the right by fixture 61, referring to Fig. 2 and Fig. 3, when sensor 143 is not detected by L-type baffle plate 142 When, the controlled motor control charging tray 11 coupled with charging tray 11 is not rotated.As bonding wire 10 is pulled, because charging tray 11 is fixed not Dynamic, roller 14 is driven and is moved up by bonding wire 10, while slide block 141 and L-type baffle plate 142 are moved up；When L-type baffle plate is moved to During the groove location of sensor 143, sensor 143 detects the presence of L-type baffle plate 142, and sensor 143 with charging tray 11 to coupling Controlled motor sending signal, controlled motor control charging tray 11 start rotate, discharge bonding wire 10, roller 14, slide block 141 and L-type Baffle plate 142 is moved down under self gravitation effect, when L-type baffle plate 142 is moved down into the groove location of sensor 145, Sensor 145 detects the presence of L-type baffle plate, the controlled motor sending signal that sensor couples for 145 casees with charging tray 11, control electricity Machine control charging tray 11 stops operating.When fixture 61 pulls bonding wire 10 to the right again, Wire Wheel group repeats aforesaid operations.

Referring to Fig. 2 and Fig. 4, bonding wire 10 drives the code-disc 151 on detection wheel 15 to rotate, and sensor 153 is by detecting code-disc 151 rotation can accurately measure the distance that bonding wire 10 is pulled, and sensor 153 transfers data to the control system of bonding machine In system, so that the opportunity that control system can cut off bonding wire 10 with precise control cutting knife 50 so that each section of cut-off weldering The length of line is controlled in qualified scope.Because roller 14 can freely up and down slide with slide block 141, therefore the pile warp of bonding wire 10 After roller 14, it is tauted under the Action of Gravity Field of roller 14 and slide block 141, the bonding wire 10 being tauted increased the accurate of measurement Degree.
