[0062] Specifically, the middle part of the boat jig 41 is uniformly provided with a plurality of bearing positions along its own length direction, and a plurality of connecting holes 411 are equidistantly distributed on the front and back sides of the boat jig 41. The lead pin product 42 includes a lead pin (421), which passes through the bearing position and is located on the lower side of the boat jig 41. The front and back sides of the boat jig 41 are extended downward and bent to form guide portions. The inner rollers 25 of the movable track assembly 2 and the outer rollers 39 of the fixed track assembly 3 slide into the two guide portions to lift the bottom of the boat jig 41.

[0063] In this embodiment, when the product assembly 4 is sent into the conveying track of the die bonder from the feeding end, the bottom of the boat jig 41 is lifted by the inner rollers 25 of the movable track assembly 2 and the outer rollers 39 of the fixed track assembly 3. The boat jig 41 is in rolling contact with the side walls of the rollers, and the rolling contact reduces friction.

[0064] After the product assembly 4 is sensed by the infeed sensing assembly 32 and the edge searching assembly 34, the product assembly 4 continues to move in the X positive direction, and when the product assembly 4 stops moving, the left first edge clamping assembly 33 clamps the side of the product assembly 4 to position it in the Y direction;

[0065] Then the left first conveying assembly 23 moves in the X negative direction to approach the product assembly 4, the connecting pin 234 of the left first conveying assembly 23 is inserted into the connecting hole 411 of the product assembly 4, and the product assembly 4 is slowly pulled back to the dispensing station;

[0066] Then when the edge searching assembly 34 detects the side of the product assembly 4, the boat-shaped jig 41 is formally searched by the edge searching assembly 34 to achieve X-direction positioning of the product assembly 4;

[0067] Then the product assembly 4 is pulled by the left first conveying assembly 23 to the dispensing station, and the product assembly 4 is conveyed above the lifting assembly 35 of the dispensing station, and then the left second edge clamping assembly 33 clamps the side of the product assembly 4 to achieve Y-direction positioning;

[0068] Then the lifting assembly 35 of the dispensing station works, the suction support block 357 of the lifting assembly 35 separates the boat-shaped jig 41 from the leaded product 42, and the leaded product 42 is sucked by the vacuum of the suction support block 357, and the dispensing equipment starts dispensing the leaded product 42;

[0069] During dispensing, the left first conveying assembly 23 and the left second conveying assembly 23 interact, the left first conveying assembly 23 is reset, the product assembly 4 is pulled by the left second conveying assembly 23, and when the dispensing area is completed, the product assembly 4 is pulled by the left second conveying assembly 23 to above the lifting assembly 35 of the die bonding station, and the left third edge clamping assembly 33 clamps the side of the product assembly 4 to achieve Y-direction positioning;

[0070] Then the lifting assembly 35 of the die bonding station works, the suction support block 357 of the lifting assembly 35 separates the boat-shaped jig 41 from the leaded product 42, and the leaded product 42 is sucked by the vacuum of the suction support block 357, and the die bonding equipment starts die bonding the leaded product 42;

[0071] During die bonding, the left second conveying assembly 23 and the left third conveying assembly 23 interact, the product assembly 4 is pulled by the left third conveying assembly 23, and when the die bonding is completed, the product assembly 4 is moved by the left third conveying assembly 23 in the X positive direction;

[0072] After the fourth left side edge assembly 33 hits the side edge of the product assembly 4, the third left side conveying assembly 23 and the fourth left side conveying assembly 23 interact, the fourth left side conveying assembly 23 drags the product assembly 4 to move along the positive direction of X, the fourth left side conveying assembly 23 moves along the negative direction of X, the pushing assembly 24 of the fourth left side conveying assembly 23 contacts the left side edge of the product, the fourth left side conveying assembly 23 drags the product assembly 4 to move along the positive direction of X and pushes the product assembly 4 out of the track until the outfeed sensing assembly 36 senses the left side of the boat jig 41, indicating that the product assembly 4 is pushed out of the track.

[0073] During the production process, according to the different widths of the boat jig 41, different widths of the dispensing support 37 and the die bonding support 38 can be replaced to cope with different widths of the boat jig 41, and the track width adjusting assembly 1 is adjusted to ensure that the product assembly 4 is normally conveyed in the conveying track of the die bonder. According to the different sizes of the product with pins 42, the suction nozzle support block 357 is replaced to ensure the positioning of the product.

[0074] It should be noted that the above technical features continue to combine to form various embodiments not listed above, which are considered to be within the scope of the present application. And for those skilled in the art, according to the above description, improvements or changes can be made, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
