DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0034] like Figure 1 , Figure 3 , Figure 7 , Fig. 9 and Fig.10 As shown, in one embodiment, a lead shearing device for diode production and processing is proposed, the device includes four stations: a loading station a, a clamping station b, a shearing station c, and a unloading station d, which are arranged obliquely, and also includes:

[0035] The main frame 1 includes a mounting platform 101 disposed on the main frame 1, a fixed plate 102 is fixedly mounted on the surface of the mounting platform 101, a waste plate 103 is fixedly mounted on the surface of the mounting platform 101, a receiving plate 104 is also fixedly mounted on the surface of the mounting platform 101, and a connecting frame 105 is fixedly mounted on the surface of the fixed plate 102;

[0036] Positioning mechanism 2: includes a positioning support block 201 mounted on the mounting platform 101, a feed hole 203 is opened on the positioning support block 201, and also includes a plurality of groups of clamping blocks 202 mounted on the mounting platform 101, each group of clamping blocks 202 includes two;

[0037] Thrust mechanism 3: drives a group of clamping blocks 202 to clamp the diode by cooperating with the cam mechanism 4;

[0038] Tension mechanism 5: cooperates with the slide mechanism 6 to drive a group of clamping blocks 202 to position the diode;

[0039] Cutting mechanism 8: performs cutting operation on the pins of the diode.

[0040] In practical application of the embodiment of the present invention, when cutting the diode pins, as shown in FIG. Figure 1 and Figure 3 As shown, the diode is placed from the feed hole 203 to the positioning support block 201 at the loading station a by an external conveying device, as shown in FIG. Figure 1 As shown, from Figure 1 When the diode is moved from the loading station a to the clamping station b, the diode is clamped by a set of clamping blocks 202 under the action of the thrust mechanism 3 and the cam mechanism 4. Fig. 9 As shown, when moving from the clamping station b to the shearing station c, under the action of the pulling mechanism 5 and the sliding groove mechanism 6, the diode is driven to limit the position through the clamping block 202. At this time, at the shearing station c, the diode is cut by the shearing mechanism 8, thereby achieving the purpose of automatic positioning and precise cutting. After the cutting is completed, due to the inclined settings of the loading station a, the clamping station b, the shearing station c, and the unloading station d, the cut pins fall into the waste tray 103 under the action of gravity, thereby achieving the purpose of automatically collecting the pin waste. At the same time, when moving from the shearing station c to the clamping station b, as shown Fig.10 As shown, in the first half of the journey, the diode is limited and reset by the action of the pulling mechanism 5 and the sliding groove mechanism 6, as shown in FIG. Figure 7 As shown, in the second half of the journey, the diode is clamped and reset through the clamping block 202 through the action of the thrust mechanism 3 and the cam mechanism 4. It should be noted here that the clamping block 202 has not yet reached the unloading station d when driving the diode to be clamped and reset. At this time, under the action of gravity, the diode slides from the feed hole 203 to the receiving tray 104, thereby completing the unloading operation of the diode, and the cycle of the four stations of loading station a, clamping station b, shearing station c, and unloading station d is completed to complete the diode shearing cycle.

[0041] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, as a preferred embodiment of the present invention, the thrust mechanism 3 includes a plurality of thrust rods 301 installed on the mounting table 101, the surface of each thrust rod 301 is coaxially slidably connected with a fixed slide 302, and the surface of each thrust rod 301 is fixedly installed with a compression spring 303, the surface of each thrust rod 301 is rotatably connected with two swing rods 304, and one end of each swing rod 304 away from the compression spring 303 is rotatably connected to the surface of a sliding rack 305, the sliding rack 305 is meshed with a rotating gear 306, the rotating gear 306 is meshed with a linkage rack 307, the surface of the linkage rack 307 is fixedly connected to the clamping block 202, and the surface of the thrust rod 301 is in contact with the cam mechanism 4.

[0042] In practical application of the embodiment of the present invention, when the material is moved from the loading station a to the clamping station b, as shown in FIG. Figure 7 and Figure 8 As shown, from Figure 7 and Figure 8 From the front view direction, at this time, the thrust rod 301 is driven to move downward under the action of the cam mechanism 4, and the downward movement of the thrust rod 301 drives the swing rod 304 to swing, and the swing of the swing rod 304 drives the sliding rack 305 to move away from the central axis of the thrust rod 301, as shown in FIG. Figure 6 As shown, from Figure 6 Looking from the front direction, at this time, the meshing action of the gears drives the linkage rack 307 to move to the left, and the independent linkage rack 307 moves to the right, thereby driving the clamping block 202 to clamp the diode. In the process from the clamping station b to the shearing station c, under the action of the cam mechanism 4, the clamping block 202 always keeps the diode clamped. In the first half of the journey from the shearing station c to the unloading station d, under the action of the cam mechanism 4, the clamping block 202 also keeps the diode clamped. In the second half of the journey from the shearing station c to the unloading station d, the cam mechanism 4 resets it through the thrust mechanism 3, so that the diode is released before reaching the unloading station d.

[0043] like Figure 7 As shown, as another preferred embodiment of the present invention, the cam mechanism 4 includes a convex disc 401 fixedly mounted on the connecting frame 105, and the inner wall of the convex disc 401 is provided with a proximal slide 402, an inner circular slide 403, a distal slide 404 and an outer circular slide 405 connected end to end, and the convex disc 401 is in contact with the thrust rod 301.

[0044] When the embodiment of the present invention is actually used, when moving from the loading station a to the clamping station b, the thrust rod 301 slides on the proximal slide 402, and the clamping block 202 is driven by the thrust mechanism 3 to clamp the diode under the action of the proximal slide 402. When moving from the clamping station b to the shearing station c, the clamping block 202 is kept clamped on the diode under the action of the inner circular slide 403. When moving from the shearing station c to the unloading station d in the first half of the journey, the clamping block 202 is kept clamped on the diode under the action of the inner circular slide 403. In the second half from the shearing station c to the unloading station d, the thrust mechanism 3 is reset under the action of the telecentric slide 404, and the clamping block 202 releases its clamping effect on the diode.

[0045] like Figure 3 , Fig. 9 and Fig.10 As shown, as another preferred embodiment of the present invention, the pulling mechanism 5 includes a plurality of pulling slides 501 installed on the mounting table 101, the end of the compression spring 303 away from the thrust rod 301 is connected to the surface of the pulling slide 501, the surface of the pulling slide 501 is fixedly installed with a fixed slide 302, the surface of the pulling slide 501 is slidably connected with a sliding rack 305, the surface of the pulling slide 501 is rotatably connected with a rotating gear 306, the surface of the pulling slide 501 is slidably connected with a linkage rack 307, the surface of the pulling slide 501 is fixedly installed with a pulling ball rod 502, the pulling slide 501 is slidably connected to the driving mechanism 7, the pulling ball rod 502 is slidably connected to the slide mechanism 6, and the driving mechanism 7 is provided with a plurality of positioning grooves 503 and pin grooves 504.

[0046] In practical application, the embodiment of the present invention is as follows: Fig. 9 As shown, when moving from the clamping station b to the shearing station c, the pull ball rod 502 is driven downward by the action of the slide mechanism 6, and then the pull slide plate 501 is driven downward, as shown in FIG. Figure 3 As shown, from Figure 3 From the front view, at this time, the tension slide plate 501 drives the clamping block 202 to move to the left through the thrust mechanism 3, thereby driving the diode to fit on the positioning groove 503, and the pin of the diode fits on the pin groove 504, thereby completing the precise positioning of the diode. At this time, after the diode is cut at the cutting station c, at this time, in the first half of the journey from the cutting station c to the unloading station d, as shown in FIG. Fig.10 As shown, the pulling mechanism 5 is reset by the action of the sliding groove mechanism 6, and at this time, the clamping block 202 drives the diode to be separated from the positioning groove 503, so as to facilitate the subsequent unloading operation of the diode.

[0047] like Fig. 9 and Fig.10 As shown, as another preferred embodiment of the present invention, the slide mechanism 6 includes a tension slide 601, a reset slide 602 and a concentric slide 603 which are connected end to end and are opened on the fixed plate 102, and the tension ball rod 502 moves along the trajectories of the tension slide 601, the reset slide 602 and the concentric slide 603.

[0048] In practical application of the embodiment of the present invention, when moving from the clamping station b to the shearing station c, as shown in FIG. Fig. 9 As shown, from Fig. 9 From the front view direction, at this time, the tension mechanism 5 is driven to move under the action of the track of the tension slide 601, thereby driving the clamping block 202 to position the diode, and completing the shearing at the shearing station c. When moving from the shearing station c to the first half of the unloading station d, as shown in FIG. Fig.10 As shown, at this time, under the action of the reset slide 602, the clamping block 202 is driven by the tension mechanism 5 to reset the diode, thereby facilitating the unloading of the diode. In other workstations during the cycle, the tension mechanism 5 is kept from moving under the action of the tension slide 601 to avoid motion interference.

[0049] like Figure 2 As shown, as another preferred embodiment of the present invention, the device also includes a driving mechanism 7, the driving mechanism 7 includes a driving motor 701 fixedly mounted on the fixed disk 102, the output end of the driving motor 701 passes through the fixed disk 102 and is rotatably connected to the fixed disk 102, the output end of the driving motor 701 is fixedly mounted with a rotating table 702, the inner wall of the rotating table 702 is slidably connected with a tension sliding disk 501, the inner wall of the rotating table 702 is fixedly mounted with a positioning support block 201, the inner wall of the rotating table 702 is slidably connected with the tension ball rod 502, a plurality of feeding holes 203 are opened on the surface of the rotating table 702, and the inner wall of the rotating table 702 is slidably connected with a thrust rod 301.

[0050] In actual application of the embodiment of the present invention, when the shearing operation of the diode is performed, the driving motor 701 starts to run, and the operation of the driving motor 701 drives the rotating table 702 to rotate. During the rotation process, through the cooperation of the thrust mechanism 3, the cam mechanism 4, the pulling mechanism 5, and the slide mechanism 6 at each workstation, the clamping block 202 drives the diode to perform positioning shearing and complete the unloading at the same time, thereby completing the circulation operation of the diode and increasing the shearing efficiency.

[0051] like Figure 1 As shown, as another preferred embodiment of the present invention, the device further includes a shearing mechanism 8, which includes a shearing knife 801 installed on the mounting table 101, and also includes a plurality of shearing grooves 802 arranged on the rotating table 702.

[0052] In actual application, when the embodiment of the present invention moves to the shearing station c, the driving mechanism 7 stops running and the shearing knife 801 starts running, and enters the feed hole 203 through the shearing groove 802 on the rotating table 702, thereby shearing the pins of the diode. After the shearing is completed, the shearing knife 801 runs out of the feed hole 203, and the driving mechanism 7 continues to run, thereby completing the cyclic shearing operation.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
