[0015] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects: 1. The cutting device and cutting process of the lead frame of the present invention are provided with a tearing member. When the tearing cylinder moves to a position where it contacts the lead frame, multiple groups of tearing cylinders are turned on to clamp the connection end of the lead frame. Then, by turning on the switch of the first driving motor, the connecting plate can be driven to move forward or backward. When the connecting plate moves forward or backward, the rightmost moving plate can be driven to move, so as to drive the scissors frame to move. After the scissors frame moves, multiple groups of tearing cylinders can be driven to move synchronously, so as to quickly tear the connection end of the lead frame. Since multiple groups of tearing cylinders can be quickly separated or combined, the tearing member as a whole can quickly tear the connection ends of the lead frame with different spacings. 2. Through the arranged cutting components, the staff can drive the cutter as a whole to perform a pre-downward operation by turning on the switch of the second driving motor. After the cutter moves to the top of the lead frame, the switch of the fourth electric cylinder can be turned on to drive the cutter as a whole to perform a second downward operation, so that the lead frame after the tearing can be quickly cut. The pre-downward movement and the second downward movement can ensure the stability of the cutter when aiming at the lead frame; 3. Through the arranged cutting member, when the cutter moves downward, the tooth plate can be driven to move downward synchronously. When the second tail rod penetrates into the airbag box and squeezes the airbag in the airbag box, the arranged airbag can effectively prevent the cutter from falling too fast and causing excessive pressure to damage the edge of the lead frame. On the other hand, the water-absorbing particles in the airbag can be released into the positioning member to complete the absorption of the waste cutting liquid. 4. Through the arranged rotary adsorption component, when the tooth plate moves down, when the serrated end of the tooth plate meshes with the second driven wheel, the second driven wheel can be driven to move, and at the same time, the first driven wheel and the guide wheel can be driven to rotate. After the guide wheel rotates, the cylindrical cam can be driven to rotate. At this time, the extension section moves along the top groove of the cylindrical cam. When the fitting wheel moves to the transition groove, the through shaft can be driven to move down and the lower adsorption cotton plate can be driven to move up as a whole. When the fitting wheel moves to the low groove and the external gear comes to the half tooth, the lower adsorption cotton plate can be driven to rotate upward, and the upper adsorption cotton plate can be rotated to the bottom. At this time, after the lower adsorption cotton plate has absorbed the waste liquid of the cutting liquid, it can be quickly replaced by the upper adsorption cotton plate. The hanging spring can be stretched during the downward movement of the through-shaft. On the one hand, the lower adsorption cotton plate can overcome the gravity of the waste liquid and swing quickly after absorbing the waste liquid. On the other hand, the lower adsorption cotton plate can provide a stable supporting force so that the lower adsorption cotton plate can stay stably in the positioning component. In addition, the lower adsorption cotton plate and the upper adsorption cotton plate can further promote the water absorption effect of the water-absorbing particles. When the tooth plate moves up, the upper adsorption cotton plate and the lower adsorption cotton plate can quickly change positions again, which is equivalent to cleverly promoting the replacement of the upper adsorption cotton plate and the lower adsorption cotton plate to absorb liquid each time the cutting operation is performed to promote interval absorption and improve the absorption effect. 5. Through the intermittent cleaning components, the staff turns on the third driving motor to rotate the toggle wheel and the toggle column. When the toggle column moves to the second toggle groove of the second conversion plate, it can drive the driving column to rotate. After the driving column rotates, it can drive the moving wheel to move along the wave groove, so that the rubber wheel can reciprocate and vibrate the positioning component to loosen the waste residue on the lead frame. When the toggle column moves to the first toggle groove of the first conversion plate, it can drive the fan blade to rotate and blow off the waste residue on the lead frame. Through the intermittent movement of the two, it can be realized. Now, loosening and blowing off impurities at the same time can further improve the waste residue removal effect. In addition, when blowing through the fan blades, on the one hand, it can also blow the waste liquid in the positioning component toward one side of the rotary adsorption component to further improve the overall rotary liquid absorption effect of the rotary adsorption component. On the other hand, when the fan blades are blowing, the water-absorbing particles can also be blown apart to further improve the liquid absorption effect of the water-absorbing particles. On the other hand, when the fan blades are blowing, the lower adsorption cotton board that absorbs the waste liquid can be dried, and the absorption effect is improved when the lower adsorption cotton board continues to participate in absorbing the liquid.

[0021] In the embodiment, Figure 1-10 A lead frame cutting device is provided, wherein the device comprises: an operating case 1 having an installation chamber therein; a positioning member 2 for positioning the lead frame, which is detachably installed in the installation chamber of the operating case 1; a three-axis adjustment member 3, which is detachably installed in the installation chamber of the operating case 1, and the three-axis adjustment member 3 is located on one side of the positioning member 2; a tearing member 4 for tearing the lead frame, which is detachably installed on the three-axis adjustment member 3, and the tearing member 4 can be adjusted by the three-axis adjustment member 3 along six directions: front, back, left, right, up, and down; a cutting member 5 for cutting the lead frame, which is detachably installed On the other side of the three-axis adjustment component 3, a tooth plate 59 is included in the cutting component 5, and the tooth plate 59 can be continuously switched between the upward state and the downward state; a rotary adsorption component 6 for adsorbing waste liquid in the positioning component 2 can be detachably installed in the installation chamber of the operating chassis 1, wherein when the tooth plate 59 is switched from the upward state to the downward state, the rotary adsorption component 6 can be triggered to operate in conjunction, and when the tooth plate 59 is switched from the downward state to the upward state, the rotary adsorption component 6 can be driven back to the initial position; an intermittent cleaning component 7 can be detachably installed in the installation chamber of the operating chassis 1, and is located on one side of the rotary adsorption component 6.

[0022] The present invention is based on an overall idea that, by arranging a tearing member 4, when the tearing cylinder 491 moves to a position in contact with the lead frame, by opening multiple groups of tearing cylinders 491, the connection end in the lead frame can be clamped, and then by opening the switch of the first drive motor 43, the connecting plate 46 can be driven to move forward or backward, and when the connecting plate 46 moves forward or backward, it can drive the rightmost moving plate 49 to move, so as to drive the scissors frame 492 to move, and after the scissors frame 492 is moved, it can synchronously drive multiple groups of tearing cylinders 491 to move, so as to quickly tear the connection end of the lead frame, and because the multiple groups of tearing cylinders 491 can be quickly separated or combined, the tearing member 4 as a whole can quickly tear the connection ends of the lead frame with different spacings; by arranging a cutting member 5, the staff can open the second drive motor 43 to start the tearing operation. The switch of the motor 54 can drive the cutter 57 to perform a pre-downward movement as a whole. After the cutter 57 moves to the top of the lead frame, the switch of the fourth electric cylinder 56 is turned on to drive the cutter 57 to perform a second downward movement as a whole, so that the lead frame after the tearing can be quickly cut. The stability of the cutter 57 when aiming at the lead frame can be ensured by the pre-downward movement and the second downward movement. The arranged cutting member 5 can drive the tooth plate 59 to move downward synchronously during the downward movement of the cutter 57. When the second tail rod 592 penetrates into the airbag box 26 and squeezes the airbag in the airbag box 26, the arranged airbag can effectively prevent the cutter 57 from damaging the edge of the lead frame due to excessive speed and pressure when falling, and can release the water-absorbing particles in the airbag into the positioning member 2 to complete the absorption of the waste cutting liquid.By deploying the rotary adsorption component 6, when the tooth plate 59 moves down, when the serrated end of the tooth plate 59 meshes with the second driven wheel 691, it can drive the second driven wheel 691 to move, and at the same time drive the first driven wheel 69 to rotate and drive the guide wheel 67 to rotate. After the guide wheel 67 rotates, it can drive the cylindrical cam 65 to rotate. At this time, the extension section 692 moves along the top groove of the cylindrical cam 65. When the fitting wheel 697 moves to the transition groove, it can drive the through shaft 695 to move down and drive the lower adsorption cotton plate 698 to move up as a whole. When the fitting wheel 697 moves to the low groove and the external gear 696 comes to the half tooth 64, it can drive the lower adsorption cotton plate 698 to rotate upward, and the upper adsorption cotton plate 699 to rotate downward. At this time, when After the lower adsorption cotton plate 698 has absorbed the waste liquid of the cutting liquid, it can be quickly replaced with the upper adsorption cotton plate 699. The hanging spring 662 can be stretched during the downward movement of the through-shaft 695. On the one hand, the lower adsorption cotton plate 698 can overcome the gravity of the waste liquid and swing quickly after absorbing the waste liquid. On the other hand, it can provide a stable supporting force for the lower adsorption cotton plate 698 to stably stay in the positioning component 2. In addition, the lower adsorption cotton plate 698 and the upper adsorption cotton plate 699 can further promote the water absorption effect of the water-absorbing particles. After the tooth plate 59 moves up, the upper adsorption cotton plate 699 and the lower adsorption cotton plate 698 can quickly switch positions again, which is equivalent to each time When performing the cutting operation, the replacement of the upper adsorption cotton plate 699 and the lower adsorption cotton plate 698 can be cleverly promoted to absorb liquid to promote interval absorption and improve the absorption effect; through the intermittent cleaning component 7, the staff turns on the third drive motor 72 to rotate the toggle wheel 73 and the toggle column 74. When the toggle column 74 moves to the second toggle groove of the second conversion plate 76, it can drive the drive column 78 to rotate. After the drive column 78 rotates, it can drive the moving wheel 795 to move along the wave groove 79, so that the rubber wheel 793 can reciprocate and vibrate the positioning component 2, so that the waste residue on the lead frame is loosened from the lead frame. When the toggle column 74 moves to the first toggle groove of the first conversion plate 75, it can drive the fan blade 77 Rotate to blow off the waste residue on the lead frame. Through the intermittent movement of the two, impurities can be blown off while loosening, which can further improve the removal effect of the waste residue. In addition, when the fan blades 77 are used for blowing, on the one hand, the waste liquid in the positioning member 2 can be blown toward one side of the rotary adsorption member 6 to further improve the overall rotary liquid absorption effect of the rotary adsorption member 6. On the other hand, when the fan blades 77 are blowing, the water-absorbing particles can be blown apart to further improve the liquid absorption effect of the water-absorbing particles. On the other hand, when the fan blades 77 are blowing, the lower adsorption cotton plate 698 that absorbs the waste liquid can be dried, and the absorption effect of the lower adsorption cotton plate 698 when it continues to absorb the liquid is improved. ;
