DETAILED DESCRIPTION

[0034] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment.

[0035] As shown in the figure, Figures 1-6 In one embodiment, a split inductive electrode cutting mechanism includes a support assembly 1 for mounting and fixing a driving assembly 4 and a cutting lower knife assembly 2.

[0036] The cutting lower knife assembly 2 is arranged in the support assembly 1, and the cutting lower knife assembly 2 includes a lower knife body 22, and detachable cutting lower knives 23 are symmetrically arranged on both sides of the lower knife body 22. The cutting lower knife assembly 2 is used for cutting the lead frame of a continuous inductor 24 electrode and limiting a single inductor 25 as a track orientation.

[0037] The cutting upper knife assembly 3 is arranged above the cutting lower knife assembly 2, and the cutting upper knife assembly 3 is used for cutting the lead frame of the continuous inductor 24 electrode and limiting the single inductor 25 to press on the cutting lower knife assembly 2.

[0038] The driving assembly 4 is connected with the cutting upper knife assembly 3, and the driving assembly 4 is used for driving the cutting upper knife assembly 3 to move downward, so that the cutting upper knife assembly 3 cooperates with the cutting lower knife assembly 2 to complete the electrode cutting.

[0039] As shown in the figure, Figures 1-2 Optionally, the support assembly 1 includes a fixed plate 11, a support column 12 and a support plate 13, wherein the support column 12 is arranged above the fixed plate 11 and below the support plate 13. The fixed plate 11 is used for fixing the cutting lower knife assembly 2, and the support plate 13 is used for fixing the driving assembly 4.

[0040] As shown in the figure, Figures 2-3 Optionally, the cutting lower knife assembly 2 includes a lower knife seat 21, a lower knife body 22 and a cutting lower knife 23. The lower knife body 22 is arranged on the lower knife seat 21 through a positioning hole; the cutting lower knife 23 is symmetrically arranged in the groove of the lower knife body 22 through a counterbore, the end face of the cutting lower knife 23 holds the inductor electrode, the inner side forms a groove for positioning and guiding the inductor body, and the two straight edges are used as the cutting edge. The cutting lower knife 23 is made of SKD11 material, and the hardness after heat treatment is HRC59±1. The hardness is high and wear-resistant. A bevel is designed on the knife body to facilitate the guided falling of the waste lead frame. The split rear edge can be directly detached for end face reduction and sharpening. After repair, the cutting lower knife assembly 2 can be directly installed and debugged without tool setting. The structure is simple, easy to process and greatly reduces the cost.

[0041] As shown in the figure, Figure 2With Figure 4 As shown in FIG. 3, the cutting upper knife assembly 3 comprises an upper knife connecting block 31, a cutting upper knife 32 and a cutting pressure block 35. The bottom of the upper knife connecting block 31 is connected to the cutting pressure block 35 by a set screw 34. The set screw 34 has a connecting and guiding effect.

[0042] The cutting pressure block 35 always presses the inductor electrode on the end face of the cutting lower knife 23 to prevent it from falling off the track during the cutting process or the lifting process. The 0.3mm*1mm clearance on both sides of the cutting pressure block 35 can prevent the single inductor 25 from being stuck in the cutting upper knife 32, because the clearance provides space for the upward bending of the electrode during the material removal process. The maximum length of the two sides of the bent electrode is less than the gap of the cutting upper knife 32. A mold spring 36 is arranged between the upper knife connecting block 31 and the cutting pressure block 35. The elastic force of the compressed mold spring 36 generates a continuous downward pressure on the cutting pressure block 35, ensuring that the single inductor 25 cannot move during the cutting process. The cutting upper knife 32 is symmetrically arranged on both sides of the upper knife connecting block 31 and can be detachably connected. The cutting lower knife 23 is used to cut the electrode by using the cutting edge and the cutting upper knife 32. The cutting upper knife 32 is made of SKD11 material and has a hardness of HRC59±1 after heat treatment. It has high hardness and wear resistance. The cutting edge can be directly detached for side face reduction and sharpening. Both the front and back sides can be used as cutting surfaces. The cutting upper knife 32 is designed with a boss at both ends. The boss has a chamfer of 0.3mm*2mm for guiding and positioning during cutting adjustment to prevent damage to the upper and lower knife molds during cutting. A guide plate 33 is arranged on the left and right outer sides of the cutting upper knife 32. The guide plate 33 is used for directional falling of the waste lead frame during cutting. After optimizing the cutting upper knife assembly 3, the cutting upper knife 32 is more durable and easier to maintain and adjust. The modification of the cutting pressure block 35 completely solves the problem of the single inductor 25 being stuck in the cutting upper knife 32. The directional effect of the newly added guide plate 33 completely solves the problem of waste lead frame remaining on the machine.

[0043] As Figures 1-2As shown, the driving assembly 4 comprises an adjustable stroke driving cylinder 41, a guide rod and a linear bearing 44. The screw rod of the adjustable stroke driving cylinder 41 is provided with a floating joint 42, which ensures that the driving force is always consistent with the guiding direction when there are other guiding assemblies. The floating joint 42 is provided with a connecting plate 43, and the connecting plate 43 is fixed to the cutting upper knife assembly 3. The top surface of the cutting upper knife assembly 3 is provided with two guide rods 45, which pass through the linear bearing 44 provided on the support plate 13 and serve as the vertical upward and downward guide of the driving assembly 4. After the adjustable stroke driving cylinder 41 is adopted, the cutting upper knife assembly 3 can be directly adjusted by the position of the tail nut during debugging, without the need to stretch the hand into the mechanism to adjust the floating joint 42, which is safer and more convenient. After the optimization of the linear bearing 44 and the guide rod 45, the maintenance space inside the split inductive electrode cutting mechanism is larger, and the debugging of each component can be visualized, which is simpler and more convenient.

[0044] Working principle: After the pre-assembly is smoothly pushed into position by the track guiding and positioning of the cutting lower knife 23 in the cutting lower knife assembly 2, the adjustable stroke driving cylinder 41 in the driving assembly 4 generates a vertical downward driving force on the connecting plate 43 through the guidance of the floating joint 42 and the guide rod 45. The cutting upper knife assembly 3 starts to move vertically downward. During this process, the cutting pressure block 35 first contacts the continuous inductor 24, and the mold spring 36 is compressed to continuously provide downward pressure. The continuous inductor 24 is firmly pressed by the cutting pressure block 35 after being pressed by the mold spring 36 and cannot move.

[0045] Further, the cutting upper knife 32 and the cutting lower knife 23 start to cut the blade, and the scrap lead frame starts to fall. At this time, it falls vertically under the guidance of the guide plate 33 and the inclined surface of the cutting lower knife 23.

[0046] Further, the adjustable stroke driving cylinder 41 resets upward, and the cutting upper knife assembly 3 starts to separate from the cutting position under the guidance of the guide. At this time, the cutting upper knife 32 separates upward during the process, and the cut electrode bends upward through the avoidance of the cutting pressure block 35 on both sides until a gap is generated between the cutting upper knife 32 and the cutting upper knife 32. During this process, the blade of the cutting upper knife 32 is lower than the blade of the cutting lower knife 23, the cutting pressure block 35 is stationary relative to the cutting lower knife 23, and the mold spring 36 slowly resets and elongates.

[0047] Further, the blade of the cutting upper knife 32 is higher than the blade of the cutting lower knife 23, the cutting pressure block 35 is still stationary relative to the cutting lower knife 23, and the mold spring 36 slowly resets and elongates until it returns to its original length. At this time, the cutting upper knife assembly 3 returns to the initial appearance of cutting, rises with the cutting pressure block 35, and the single inductor 25 is separated from the cutting pressure block 35 and remains in the cutting lower knife assembly 2. Finally, the adjustable stroke driving cylinder 41 resets to the cutting end position, and the cutting is completed. Figure 3The shown continuous inductor 24 becomes a single inductor 25 after cutting.

[0048] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
