Description

Technical Field

[0001] This utility model relates to the field of bridge rectifier frame four-chip pin borrowing bow-shaped cutting technology, specifically a bridge rectifier frame chip pin borrowing bow-shaped cutting forming equipment. Background Technology

[0002] In the field of modern electronic equipment manufacturing, bridge rectifiers, as important electronic components, are widely used in various circuits that need to convert alternating current to direct current, such as power adapters, chargers, and power modules for electronic devices. As the core component of a bridge rectifier, the quality of its pin fabrication directly affects the performance of the bridge rectifier and the stability and reliability of the electronic equipment.

[0003] Currently, traditional manufacturing processes for four-chip pins face significant technical bottlenecks, particularly in the cutting stage. Traditional processes commonly employ a "one-cut" method, where the pins are horizontally and flush with the cutter using a fixed tool. While simple to operate, this method is limited by the linear nature of the cut trajectory, resulting in a narrow, horizontally flush plane for the pins to bond to, with a small bonding area. This deficiency directly leads to insufficient solder-pin contact area in subsequent soldering processes, easily causing problems such as cold solder joints and detachment. This not only reduces the electrical connection stability of the four-chip but can also cause circuit failures due to poor soldering, even affecting the lifespan of the entire electronic device. Utility Model Content

[0004] The purpose of this invention is to provide a bridge rectifier frame chip pin borrowing bow-shaped cutting and forming device. By setting several cutting blades at the bottom of the upper cutting mold, and setting bow-shaped cutting edges at the bottom of the cutting blades, four chips can be cut, solving the problem of small pin soldering surface area and short pins caused by traditional cutting methods.

[0005] To address the problems in the existing technology, this utility model provides a bridge rectifier frame chip pin borrowing bow-shaped cutting and forming device for cutting off four chip bodies from the bridge rectifier frame body. The device includes: a cutting device body, which comprises a worktable and a stamping plate capable of vertical movement; a lower cutting die, which can fix the top of the worktable to support the bridge rectifier frame body; and an upper cutting die, which can be installed on the bottom of the stamping plate for cutting the bridge rectifier frame body. The bottom of the upper cutting die is also provided with several cutting blades capable of cutting off the four chip bodies from the bridge rectifier frame body, and each cutting blade is provided with a bow-shaped cutting edge for cutting off the pins at the connection between the bridge rectifier frame body and the four chip bodies.

[0006] Preferably, the bottom of the upper cutting mold is also uniformly provided with movable plates that can press on the four chip bodies, and the movable plates can move up and down in the upper cutting mold.

[0007] Preferably, the upper cutting mold further includes a reset spring for resetting the movable plate, with the bottom end of the reset spring connected to the top of the movable plate and the top end of the reset spring connected to the upper cutting mold.

[0008] Preferably, the top of the lower cutting mold is further provided with positioning posts on both sides for positioning the bridge trolley frame body.

[0009] Preferably, the bottom of the upper cutting mold is also provided with a positioning hole that cooperates with the positioning post, so that when the lower cutting mold and the upper cutting mold are closed, the positioning post can be inserted into the positioning hole.

[0010] Preferably, the cutting device body includes support rods vertically arranged at the four corners of the top of the workbench, and a top plate is fixed to the top of the support rods. The stamping plate is connected to the support rods, and a first telescopic drive member is vertically arranged at the center of the top of the top plate. The output end of the first telescopic drive member is connected to the stamping plate.

[0011] Preferably, the back of the cutting device body is also provided with a storage tray for storing four chip bodies, and the cutting device body is also provided with a material picking component that can transfer the four chip bodies to the storage tray.

[0012] Preferably, the material handling assembly includes a distributor capable of reciprocating from the back to the front of the workbench, and suction cups are evenly arranged on the distributor. The material handling assembly also includes slide rails installed on both sides of the workbench, a movable frame slidably arranged on the slide rails, and a second telescopic drive member vertically arranged on the movable frame. The output end of the second telescopic drive member is connected to the distributor. The material handling assembly also includes a third telescopic drive member arranged on both sides of the back of the workbench for driving the distributor to move back and forth.

[0013] The advantages of this application compared to the prior art are as follows: This application uses a lower cutting mold and an upper cutting mold to form the core cutting mechanism. The lower cutting mold supports and positions the bridge rectifier frame body, ensuring no displacement deviation during cutting. The bottom of the upper cutting mold integrates a cutting blade with several arc-shaped cutting edges. When the lower and upper cutting molds perform a mold closing action, the cutting blade moves downwards synchronously with the upper cutting mold. The arc-shaped cutting edges act on the connection between the four-chip body and the bridge rectifier frame body, cutting off the connection through shearing force, thus completing the separation process of the leads and the frame. During the cutting process, the special structure of the arc-shaped cutting edges gives it a dual function: on the one hand, the arc-shaped cutting edges can reliably cut off the connection between the four-chip body and the bridge rectifier frame body, achieving physical separation of the leads and the frame; on the other hand, by utilizing the extension characteristics of the arc-shaped trajectory, the arc-shaped cutting edges can remove part of the structure on the bridge rectifier frame body. This design allows for more effective contact area at the base of the four chip body pins, thereby significantly increasing the pin length and the actual area of ​​the soldering surface. This provides more space for solder bonding in subsequent soldering processes, solving the technical problem of insufficient soldering surface in traditional cutting processes.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] The present invention aims to provide a cutting and forming device for cutting four chip bodies 1001 from a bridge rectifier frame body 100. The cutting position on the bridge rectifier frame body 100 extends to the frame of the bridge rectifier frame body 100, so that the pins of the cut four chip bodies 1001 are longer than those of existing chip pins, which facilitates subsequent processing.

[0027] Reference Figures 1-10 As shown, this utility model provides a bridge rectifier frame chip pin borrowing bow-shaped cutting forming device for cutting off four chip bodies 1001 on the bridge rectifier frame body 100. It includes: a cutting device body 1, which includes a worktable 11 and a stamping plate 13 that can move up and down; a lower cutting mold 2, which can fix the top of the worktable 11 to support the bridge rectifier frame body 100; an upper cutting mold 3, which can be installed on the bottom of the stamping plate 13 to cut the bridge rectifier frame body 100; the bottom of the upper cutting mold 3 is also provided with a plurality of cutting blades 32 that can cut off the four chip bodies 1001 from the bridge rectifier frame body 100, and the cutting blades 32 are also provided with bow-shaped cutting edges 321 for cutting off the pins at the connection between the bridge rectifier frame body 100 and the four chip bodies 1001.

[0028] During operation, the bridge rectifier frame body 100 is first placed on the lower cutting mold 2, which provides stable support for the bridge rectifier frame body 100. Then, the equipment is started, and the stamping plate 13 in the cutting device body 1 begins to move downward, driving the upper cutting mold 3 installed at its bottom to move downward as well. As the upper cutting mold 3 descends, the cutting blade 32 at its bottom gradually approaches the bridge rectifier frame body 100. When the cutting blade 32 contacts the bridge rectifier frame body 100 and applies sufficient pressure, the arc-shaped cutting edge 321 on the cutting blade 32 cuts the pins at the connection between the bridge rectifier frame body 100 and the quad chip body 1001. The arc-shaped cutting edge 321 can remove part of the structure on the bridge rectifier frame body 100 to complete the entire cutting and forming process, so that more effective contact area is retained at the root of the pins of the quad chip body 1001, thereby significantly increasing the pin length and the actual area of ​​the solder surface. After the cutting is completed, the stamping plate 13 moves upward, driving the upper cutting mold 3 back to the initial position. At this time, the cut four-chip body 1001 can be taken out of the equipment for subsequent operations and processing.

[0029] The bottom of the upper cutting mold 3 is also evenly provided with movable plates 33 that can press against the four-chip body 1001, and the movable plates 33 can move up and down in the upper cutting mold 3. The upper cutting mold 3 also includes a reset spring for resetting the movable plates 33, and the bottom end of the reset spring is connected to the top of the movable plates 33, and the top end of the reset spring is connected to the upper cutting mold 3.

[0030] During the descent of the upper cutting mold 3, its bottom movable plate 33 first contacts the four-chip body 1001. As the upper cutting mold 3 continues to descend, the movable plate 33 moves upward within the upper cutting mold 3 and compresses the return spring. After the upper cutting mold 3 continues to descend a certain distance, the cutting blade 32 contacts the bridge rectifier frame body 100. Under the continuous pressure applied by the stamping plate 13, the four-chip body 1001 is tightly pressed down. The arc-shaped cutting edge 321 on the cutting blade 32 cuts the pins at the connection between the bridge rectifier frame body 100 and the four-chip body 1001. After the cutting is completed, the stamping plate 13 moves upward, driving the upper cutting mold 3 to rise. At this time, the return spring pushes the movable plate 33 back to its initial position under the action of elasticity.

[0031] The lower cutting mold 2 has positioning posts 21 on both sides of its top for positioning the bridge trolley frame body 100. The bottom of the upper cutting mold 3 has positioning holes 31 that cooperate with the positioning posts 21. When the lower cutting mold 2 and the upper cutting mold 3 are closed, the positioning posts 21 can be inserted into the positioning holes 31. During the descent of the upper cutting mold 3, the positioning posts 21 on the lower cutting mold 2 gradually approach the positioning holes 31 at the bottom of the upper cutting mold 3. When they approach the mold closing position, the positioning posts 21 are accurately inserted into the positioning holes 31, achieving precise alignment between the upper cutting mold 3 and the lower cutting mold 2.

[0032] The cutting device body 1 includes support rods 12 vertically arranged at the four corners of the top of the workbench 11, and a top plate 14 is fixed to the top of the support rods 12. A stamping plate 13 is connected to the support rods 12. A first telescopic drive member 15 is vertically arranged at the center of the top of the top plate 14. The output end of the first telescopic drive member 15 is connected to the stamping plate 13.

[0033] The first telescopic drive component 15 starts working, with its output end extending downwards to push the stamping plate 13 downwards along the support rod 12. Since the upper cutting die 3 is installed at the bottom of the stamping plate 13, the upper cutting die 3 also descends along with the stamping plate 13.

[0034] The back of the cutting device body 1 is also provided with a storage tray 5 for storing four chip bodies 1001. The cutting device body 1 is also provided with a material picking component 4 that can transfer the four chip bodies 1001 to the storage tray 5. The material picking component 4 includes a diverter 41 that can reciprocate from the back to the front of the worktable 11. The diverter 41 is also evenly provided with suction cups 411. The material picking component 4 also includes slide rails 44 installed on both sides of the worktable 11. A moving frame 42 is slidably arranged on the slide rails 44. A second telescopic drive member 43 is vertically arranged on the moving frame 42. The output end of the second telescopic drive member 43 is connected to the diverter 41. The material picking component 4 also includes a third telescopic drive member 45 arranged on both sides of the back of the worktable 11 for driving the diverter 41 to move back and forth.

[0035] After cutting, the third telescopic drive 45 starts working, pushing the distributor 41 forward from the back of the worktable 11, so that the suction cup 411 on the distributor 41 reaches above the cut four-chip body 1001. Next, the output end of the second telescopic drive 43 extends downward, driving the distributor 41 downward, so that the suction cup 411 approaches the four-chip body 1001 and generates negative pressure, adsorbing the four-chip body 1001. Then, the output end of the second telescopic drive 43 retracts upward, lifting the distributor 41 and the adsorbed four-chip body 1001. Simultaneously, the third telescopic drive 45 works in the opposite direction, pulling the distributor 41 from the front of the worktable 11 backward, transferring the four-chip body 1001 above the storage tray 5. Finally, the output end of the second telescopic drive 43 extends downward again, so that the suction cup 411 approaches the storage tray 5 and releases the negative pressure, placing the four-chip body 1001 in the storage tray 5.

[0036] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
