Description

Technical Field

[0001] This utility model relates to the technical field of thyristor production equipment, specifically a thyristor forming and unloading structure. Background Technology

[0002] In the field of thyristor manufacturing, there are two main molding processes based on product structure differences: one is the lead-cutting type thyristor, which only requires a lead-cutting process after molding; the other is the screw-locking type thyristor, which requires an additional screw-locking process for assembly and fixation. Existing thyristor production equipment was initially designed to accommodate screw-locking type thyristors. These products, after screw-locking assembly, form a regular combined structure with high shape consistency and stable gripping points. Whether manually gripped or automatically gripped, they can be easily operated, smoothly connecting to subsequent production processes and meeting the continuous operation requirements of the production line.

[0003] As market demand for sheared-lead thyristors increases, companies need to utilize existing screw-fastening machine production lines to process this type of product. However, sheared-lead thyristors present significant challenges in gripping: after the leads are cut, the lack of a regular shape and stable support provided by the screw-fastening structure, coupled with the thin leads that are prone to slight deformation due to the cutting process, makes it difficult for traditional gripping mechanisms to accurately position them. Furthermore, the compact overall structure of sheared-lead thyristors lacks stable clamping points, making manual gripping inefficient, labor-intensive, and prone to damage to leads or product defects due to improper operation. The thyristors fall off, and the existing equipment is not designed with a suitable conveying and transfer structure for this type of product. This directly leads to the inability of the sheared-lead thyristors to be smoothly transferred after shearing on the screw fastening machine production line, resulting in production interruptions, a decrease in product qualification rate, and other problems. This seriously restricts the compatibility of the production line and the overall production efficiency. Therefore, it is necessary to provide a method that can add a dedicated pushing mechanism to the existing screw fastening machine to make up for the lack of function of the original equipment in grabbing and transferring sheared-lead thyristors, thereby improving the compatibility of the screw fastening machine production line with the two types of thyristor products and ensuring production continuity and efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a thyristor forming and unloading structure to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a thyristor forming and unloading structure, comprising: Cutting plate; The unloading assembly includes a connecting plate, a rotating hole, a rotating disk, and a first connecting column. The connecting plate is fixed to one side of the upper end of the unloading plate, the rotating hole is opened in the center of the connecting plate, the rotating disk is rotatably installed inside the rotating hole, and the first connecting column is fixed to one side of the upper surface of the rotating disk.

[0005] Furthermore, a fixing frame is fixed to the lower surface of the connecting plate, a motor is fixed inside the fixing frame, and the output end of the motor is fixedly connected to the rotating disk. A material frame is installed at the lower end of the feeding plate.

[0006] Furthermore, a movable rod is sleeved on the outer surface of the first connecting post, and a second connecting post is fixed on the upper surface of the other end of the movable rod.

[0007] Furthermore, a connecting ring is fitted onto the outer surface of the second connecting post, a connecting rod is fixed to one side of the connecting ring, a pusher plate is fixed to one end of the connecting rod, and the pusher plate is located on the upper surface of the feed plate.

[0008] Furthermore, a fixing plate is fixed in the middle of the upper surface of the feeding plate, and a movable hole is opened in the center of the fixing plate, and the connecting rod is sleeved inside the movable hole.

[0009] Furthermore, it also includes an installation component, which includes a slot, a mounting hole, and a spring.

[0010] Furthermore, one end of the spring is fixed with a locking pin, the end of which extends into the slot.

[0011] This utility model has the following beneficial effects: This invention utilizes a feeding plate, a material frame, a fixing frame, a motor, and an unloading assembly. After the thyristor is formed and sheared, it falls onto the feeding plate.

The pushing mechanism uses the rotation of the rotating disk to drive a series of linkage mechanisms. The structure is relatively compact, occupies little space, and is suitable for installation on various thyristor production lines. Moreover, the connection and transmission methods between the components are relatively simple and reliable, and are not prone to failure during long-term operation, ensuring the continuity of production.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a thyristor forming and unloading structure, comprising: A fixing frame 13 is fixed on the lower surface of the feeding plate 11 and the connecting plate 21. A motor 14 is fixed inside the fixing frame 13, and the output end of the motor 14 is fixedly connected to the rotating disk 22. A material frame 12 is installed at the lower end of the feeding plate 11. The feeding plate 11 serves as a temporary receiving platform for the sheared thyristors and is the initial supporting component of the entire pushing process. The material frame 12 is the final collection component for the thyristors. When the pusher plate 28 pushes the thyristors on the feeding plate 11 to the edge, the thyristors will naturally fall into the material frame 12. The fixing frame 13 provides stable mounting support for the motor 14, which is the power output source of the entire pushing mechanism. After startup, the output end of the motor 14 will drive the rotating disk 22 to rotate at a constant speed, converting electrical energy into mechanical rotational kinetic energy, providing continuous and stable power for the subsequent movement of the linkage assembly.

[0018] The unloading assembly includes a connecting plate 21, a rotating hole 211, a rotating disk 22 and a first connecting post 23. The connecting plate 21 is fixed to one side of the upper end of the unloading plate 11. The rotating hole 211 is opened in the center of the connecting plate 21. The rotating disk 22 is rotatably installed inside the rotating hole 211. The first connecting post 23 is fixed to one side of the upper surface of the rotating disk 22. The connecting plate 21 provides a rotating mounting base for the rotating disk 22 through the rotating hole 211 in the center. The diameter of the rotating hole 211 is precisely matched with the outer diameter of the rotating disk 22, which not only ensures that the rotating disk 22 can rotate flexibly in the hole, but also restricts the radial offset of the rotating disk 22, so as to avoid the shaking of the rotating disk 22 during operation. When the motor 14 drives it to rotate, the rotating disk 22 will synchronously transmit the rotational motion of the motor to the first connecting post 23 on the upper surface. Through its own disc structure, the single rotational power of the motor is converted into the circular motion of the first connecting post 23.

[0019] A movable rod 24 is sleeved on the outer surface of the first connecting post 23. A second connecting post 25 is fixed on the upper surface of the other end of the movable rod 24. A connecting ring 26 is sleeved on the outer surface of the second connecting post 25. A connecting rod 27 is fixed on one side of the connecting ring 26. A pusher plate 28 is fixed on one end of the connecting rod 27. The pusher plate 28 is located on the upper surface of the feed plate 11. A fixing plate 29 is fixed in the middle of the upper surface of the feed plate 11. A movable hole 291 is opened in the center of the fixing plate 29. The connecting rod 27 is sleeved inside the movable hole 291. When the first connecting post 23 performs a circular motion, one end of the movable rod 24 swings accordingly, simultaneously transmitting the motion to the second connecting post 25 at the other end through its rod-like structure. As the movable rod 24 swings, the second connecting post 25 follows suit in an arc-shaped motion, while the connecting ring 26 can rotate freely on its outer surface. This prevents the swing of the movable rod 24 from generating lateral torque on the connecting rod 27, ensuring that the connecting rod 27 can move stably in a horizontal position. The connecting ring 26 can rotate freely around the second connecting post 25, thus enabling the second connecting post 25 to... The arc motion is converted into the horizontal linear motion of the connecting rod 27. Driven by the connecting ring 26 and limited by the movable hole 291, the connecting rod 27 can only make horizontal reciprocating motion inside the movable hole 291. When the connecting rod 27 makes horizontal reciprocating motion, the pusher plate 28 will move back and forth on the upper surface of the feed plate 11. When moving forward, it can push the thyristor on the feed plate 11 toward the material frame 12. The diameter of the movable hole 291 is precisely matched with the outer diameter of the connecting rod 27, allowing the connecting rod 27 to make horizontal reciprocating motion only.

[0020] Working principle: After the thyristor is formed and cut, it falls onto the feeding plate 11. The motor 14 is started, and the motor 14 drives the rotating disk 22 to rotate. The rotation of the rotating disk 22 drives the first connecting column 23 to rotate. The first connecting column 23 drives one end of the movable rod 24 to rotate circumferentially. The other end of the movable rod 24 drives the connecting ring 26 to rotate. Under the limit of the movable hole 291, the connecting rod 27 moves horizontally back and forth inside the movable hole 291, so that the connecting rod 27 drives the pusher plate 28 to move horizontally back and forth, pushing the thyristor on the feeding plate 11 into the lower material frame 12. In this step, the pushing mechanism uses the rotation of the rotary disk 22 to drive a series of linkage mechanisms. The structure is compact and occupies little space, making it suitable for installation on various thyristor production lines. Moreover, the connection and transmission methods between the components are relatively simple and reliable, and it is not prone to failure during long-term operation, thus ensuring the continuity of production.

[0021] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The mounting assembly includes a slot 31, a mounting hole 32, and a spring 33. The slot 31 is located on both sides of the lower end of the feed plate 11, and the mounting hole 32 is located on both sides inside the material frame 12. There are two springs 33, which are fixed inside the corresponding mounting holes 32. One end of the spring 33 is fixed with a locking post 34, and the end of the locking post 34 extends into the slot 31. The slot size of the slot 31 matches the end of the pin 34, providing a precise embedding space for the pin 34. It is the positioning slot for the material frame 12 to connect with the feed plate 11. The mounting hole 32 provides a mounting cavity for the spring 33 and the pin 34, and restricts the deformation direction of the spring 33 to only allow horizontal extension and contraction, ensuring that the elastic force can be accurately applied to the pin 34. As an elastic power source, the spring 33 is in a naturally extended state before the material frame 12 is installed, pushing the pin 34 to extend outward from the mounting hole 32. When the material frame 12 continues to move upward until the pin 34 is completely aligned with the slot 31, the elastic potential energy stored in the spring 33 is released, pushing the end of the pin 34 to quickly embed into the slot 31. At this time, the pin 34 and the slot 31 form a rigid engagement, and the material frame 12 is firmly fixed to the lower end of the feed plate 11, completing the installation and fixing.

[0022] Working principle: When the material frame 12 needs to be filled with thyristors or the material frame needs to be replaced, simply press the two retaining posts 34 on both sides of the material frame 12 inside. The pressing action will cause the retaining posts 34 to retract into the mounting hole 32 against the elastic force of the spring 33 until the end of the retaining post 34 is completely disengaged from the slot 31. At this time, the locking constraint between the material frame 12 and the feed plate 11 is released. Simply pull the material frame 12 down to achieve quick separation between the two. After the operation is completed, the spring 33 will push the retaining posts 34 to reset, preparing for the next installation. This step utilizes the elastic engagement mechanism of spring 33 and locking post 34 to achieve easy installation and disassembly of material frame 12 and material plate 11 with a simple push and a simple press. No screwdrivers, wrenches or other tools are required throughout the process, and a single person can complete the assembly or disassembly in a few seconds.
