[0026] The chip adsorption block 34 is coaxially fixed to the rotating shaft 33, and the rotating shaft 33 is connected to the rotating motor 31. The rotating motor 31 controls the rotation of the rotating shaft 33 to drive the chip adsorption block 34, so that the chip adsorption block 34 can perform chip adsorption and chip loading operations at different angles. The rotating motor 31 is fixed to the motor mounting plate 32, and the motor mounting plate 32 is fixed to one end of the lifting and pushing plate 24. The other end of the lifting and pushing plate 24 is provided with a rotating motor sensor 38 for sensing the rotation angle of the rotating shaft 33; at the same time, both ends of the rotating shaft 33 are fixed with bearings 36, and the bearings 36 are installed on the column 35, and the column 35 is fixed to the side of the lifting and pushing plate 24 close to the rotating shaft 33;

[0028] See also Figure 4 In order to enable the above-mentioned rotating module 3 to complete the chip suction and chip loading operations at different heights, in this embodiment, it includes a lifting module 2 composed of a chip inserting plate 21, a lifting electric cylinder 23, a lifting slide 22, an upper limit block 252, a limit block 253 and a lower limit block 251;

[0029] A lifting push plate 24 is fixed to one end of the lifting slide 23 close to the rotating module 2. The lifting slide 23 is connected to one side of the lifting electric cylinder 22. The other side of the lifting electric cylinder 22 is fixed to the inserting plate 21. The lifting slide 23 is driven by the lifting electric cylinder 22 to drive the lifting movement of the rotating module 3, so as to complete the chip absorption at a certain height, and rotate the chip into the fixture at another height to complete the chip loading operation.

[0030] At the same time, an upper limit block 252 is installed on the side parallel to the sliding direction of the lifting cylinder 22 and the lifting slide 23, and a limit block 253 is installed on the side of the lifting slide 23 on the same side as the upper limit block 252.

The first linear slider 191 is connected to the first guide rail 151, and the second linear slider 192 is connected to the second guide rail 152. The first guide rail 151 and the second guide rail 152 are both fixed on the work surface 7.

[0034] An origin sensing sheet 101 is also installed on the side of the insert base plate 18 parallel to its sliding direction. The origin sensing sheet 101 moves along with the movement of the insert base plate 18. The origin sensor 102 is installed on the work table 7. The origin sensing sheet 101 stops sliding when it moves to the origin sensor 102. An upper limit block 10 is installed on the side of the insert base plate 18 close to the screw fixing seat 12. When the screw nut 16 drives the insert base plate 18 to slide toward the screw fixing seat 12, the upper limit block 10 contacts the screw fixing seat 12, thereby limiting the sliding of the insert base plate 18 in this direction.

[0035] See also Figure 6 In order to complete the chip loading operation of the rotating module 3, in this embodiment, it also includes a fixture module 4 composed of a driving electric cylinder 41, a slide 42, a chip inserting fixture 43, an upper limit block 44, a limit block 45 and a lower limit block 46;

[0036] The fixture modules 4 are installed in pairs at mirror-symmetrical positions, and are divided into a left fixture module and a right fixture module. One side of the driving electric cylinder 41 is fixed to the top plate 8 of the working machine, and the other side is connected to the slide 42. The slide 421 of the left fixture module is close to the end of the slide 422 of the right fixture module. The insert fixture 431 is installed. Similarly, the slide 422 of the right fixture module is also installed with an insert fixture 432.

[0037] An upper limit block 44 is installed on the side of the driving electric cylinder 41 parallel to the sliding direction of the slide 42, and a limit block 45 is installed on the side of the slide 42 on the same side as the upper limit block 44.

A lower limit block 46 is installed on the side of the driving electric cylinder 41 perpendicular to the sliding direction of the slide 42. The slide 42 slides and touches the lower limit block 46, thereby limiting the slide 42 from sliding in this direction.

[0039] See also Figure 7 and Figure 8 In order to enable the chip to be smoothly transferred to the position to be absorbed by the chip adsorption block 34, in this embodiment, it also includes a feeding mechanism 5 consisting of a direct vibration block 54, a vibration plate connecting plate 55, a vibration plate conveying track 56, a direct vibration controller 51, a direct vibration damping bottom plate 52, a direct vibration connecting piece 53, a chip stop bar 562 and a direct vibration rear stop bar 561;

[0040] The vibration plate conveying track 56 includes a chip baffle 562 and a straight vibration rear baffle 561. The chip baffle 562 is installed in the middle of the vibration plate conveying track 56, dividing the vibration plate conveying track 56 into a conveying end and a loading end. The straight vibration rear baffle 561 is installed at the end of the conveying end away from the chip baffle 562 to prevent chips from falling. At the same time, a groove track of the size of the chip is set on the surface of the conveying end, and a groove track of the same size connected to the conveying end is also set at the loading end.

[0041] The direct vibration controller 51 and the direct vibration damping base plate 52 are both fixed to the work surface 7, and direct vibration connecting plates 53 are installed at both ends of the direct vibration damping base plate 52, and the direct vibration connecting plates 53 connect the two ends of the direct vibration block 54;

[0042] When the chip is transmitted, the chip is placed on the conveying end of the vibration plate conveying track 56. Under the vibration of the straight vibration block 54, the chip falls into the groove track at the conveying end. The chip that does not fall into the groove track is blocked by the chip blocking bar 562 until it falls into the groove track after vibration. The chip that falls into the groove track is transmitted to the loading end, and the chip at the loading end is adsorbed by the chip suction nozzle 34, thereby completing the chip transmission work.

[0043] When in use, two pieces of inserts that have been formed by the forming machine are respectively placed in the insert clamps 431 and 432 of the left clamp module and the right clamp module, and the chip is placed in the vibration plate conveying track 56. Then, the device start button is pressed, and the linear sliding module 1 drives the chip adsorption block 34 of the rotating module 3 to move to the feeding end of the vibration plate conveying track 56 of the feeding mechanism 5. Then, the chip adsorption block 34 of the rotating module 3 uses vacuum negative pressure to adsorb the chip. After the chip is absorbed, the linear sliding module 1 drives the rotating module 3 to move to the position where the clamp module 4 is placed for chip loading, and the rotating motor 3 is rotated. 1 Rotate the rotating shaft 33 to drive the chip adsorption block 34 to rotate, rotate the chip to the position to be loaded, and then the lifting module 2 drives the rotating module 3 to move upward to lift the chip on the chip adsorption block 34 to the middle of the insert clamp, and then the left clamp module and the right clamp module perform a clamping movement to clamp the chip between the two wires to complete the mold closing. The chip adsorption block 34 is equipped with 32 suction nozzles, which can complete 32 sets of wire clamps at a time. After the loading is completed, all modules return to the initial position, and the loading action is completed. Then take out the fixture that has completed the loading, and then proceed to the next step of tinning.

[0044] The advantages of the utility model are:

[0045] 1) The chip adsorption block is equipped with 32 chip adsorption ports, which can use vacuum negative pressure to adsorb chips and can adsorb 32 groups of chips at the same time, thus improving the chip absorption efficiency.
