Description

Technical Field

[0001] The utility model relates to the technical field of diode processing, in particular to a pin cutting device used for diode processing. Background Art

[0002] A diode processing and cutting device is a device used to cut the pins of a diode. There are two pins at both ends of the diode. The length of the pins produced is generally longer than the length required for actual use. Therefore, people need to cut off the excess pins when using them, so a diode processing and cutting device is needed.

[0003] According to the announcement number (CN212598565U), a diode processing and cutting device is proposed, which includes a base, a gantry is fixedly installed on the upper part of the base, a cutter is slidably connected to the inner side of the gantry, and a cylinder is fixedly installed at the center position of the top of the gantry. The upper part of the base is located on the inner side of the gantry and is provided with a diode clamping mechanism. By holding the handle again and pulling the pin to one side until one end of the pin can be inserted into the inside of the socket, after releasing the handle, the elasticity of the spring tightens the pin to fix the fixing cover, completing the positioning of the diode, making it convenient to clamp and fix the diode, and also protecting the diode. On the one hand, it avoids the phenomenon that the diode is damaged by the cutter when cutting the pin, and on the other hand, it also avoids the phenomenon that the diode is displaced or skewed when cutting the pin.

[0004] However, the above solution has certain problems when cutting the diode pins. If the pins are too long, the extended pins will have no support during the cutting process, which will put a huge force on the connection between the diode and the pins. Under the action of this strong external force, the pins are likely to bend or even break in severe cases. Once this happens, it will inevitably have a negative impact on the normal use of the subsequent diode in the circuit, leading to a series of potential failure risks. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-4A diode cutting device includes a base plate 1, a movable cutting assembly is provided above the base plate 1, a fixed mold 8 is fixedly installed on the top side of the base plate 1, a plurality of slots 9 are provided on the top side of the fixed mold 8, a pressing assembly is provided above the fixed mold 8, and the fixed mold 8 is provided with a through opening, a second motor 14 is fixedly installed on the bottom side of the base plate 1, the output end of the second motor 14 rotates through the base plate 1 and the fixed mold 8 and is rotatably connected to the inner wall of the top side of the through opening, a gear 15 is fixedly sleeved on the outer side of the output end of the second motor 14, and a first tooth plate 16 and a second tooth plate 17 are respectively provided on the outer side of the gear 15, and the first tooth plate 16 and the second tooth plate 17 are both meshed with the gear 15, and the first tooth plate 16 and the second tooth plate 17 are fixedly connected to the first extension plate 18 and the second extension plate 19 on the side away from each other, respectively. The top sides of the extension plate 18 and the second extension plate 19 are both on the same horizontal line with the top side of the fixed mold 8, and a guide assembly is provided in the through opening. By providing the first extension plate 18 and the second extension plate 19, when cutting a diode with a longer pin, the gear 15 can be driven to rotate counterclockwise by starting the second motor 14. Because the gear 15 is engaged with the first tooth plate 16 and the second tooth plate 17, when the gear 15 rotates counterclockwise, the first tooth plate 16 and the second tooth plate 17 will move away from each other, thereby causing the first extension plate 18 and the second extension plate 19 to move away synchronously. After moving away, the first extension plate 18 and the second extension plate 19 can support the longer pin, avoiding the situation where the cutting force will cause the connection between the diode and the pin to be subjected to excessive force when the longer pin is not supported, thereby causing bending or breaking.

[0022] Specifically, the mobile cutting assembly includes two cylinders 2 fixedly installed on the bottom side of the base plate 1, the output ends of the two cylinders 2 pass through the base plate 1 and are fixedly connected to the same connecting block 3, the connecting block 3 is provided with a long slot, and a first motor 4 is fixedly installed on one side of the connecting block 3, the output end of the first motor 4 rotates to pass through the connecting block 3 and is rotatably connected to the inner wall of one side of the long slot, a slider 5 is slidably sleeved on the outer side of the output end of the first motor 4, a connecting plate 6 is fixedly installed on the bottom side of the slider 5, and a cutter 7 is fixedly installed on the bottom side of the connecting plate 6, and the cutter 7 faces the base plate 1. After the diode is fixed, the slider 5 can be driven to move horizontally by the operation of the first motor 4, and when the slider 5 moves horizontally, it can synchronously drive the cutter 7 to move. When the cutter 7 moves to the position where the pin needs to be cut, the connection block 3 is driven downward by the operation of the two cylinders 2. When the connection block 3 moves downward, the cutter 7 can cut to the position where the pin needs to be cut, thereby completing the diode cutting process.

[0023] Specifically, the clamping assembly includes two electric push rods 13 fixedly installed on the bottom side of the base plate 1, and the output ends of the two electric push rods 13 both penetrate the base plate 1 and are fixedly connected to the side plate 12. The two side plates 12 are fixedly connected to the same movable mold 10 on the side close to each other. The movable mold 10 is provided with multiple card holes 11, and the multiple card holes 11 are on the same vertical horizontal line as the multiple card slots 9. The multiple card holes 11 are provided through the movable mold 10. When the diode is placed and needs to be fixed, the two electric push rods 13 are started to run. The operation of the two electric push rods 13 will drive the movable mold 10 to move downward. In the process of downward movement, the multiple card holes 11 provided on the movable mold 10 will be aligned with the multiple card slots 9, thereby fixing the diode in the card slot 9 and avoiding displacement of the diode during the cutting process.

[0024] Specifically, the guide assembly includes two rails 21 fixedly installed on the bottom inner wall through the opening, and both rails 21 are provided with guide grooves, and guide blocks 20 are slidably installed in both guide grooves. The sides of the two guide blocks 20 that are close to each other are fixedly connected to the sides of the first tooth plate 16 and the second tooth plate 17 that are away from each other. By providing two guide blocks 20, the two guide blocks 20 can provide stable guiding and limiting effects when the first tooth plate 16 and the second tooth plate 17 move, so that they will not deviate when they move relative to each other and away from each other.

[0025] Specifically, the base plate 1 is provided with two square holes, and two collection boxes 22 are provided on the bottom side of the base plate 1. The two collection boxes 22 are respectively located below the two square holes. By providing two collection boxes 22, the two collection boxes 22 can collect the cut pins, which is convenient for subsequent unified processing.

[0026] The pin cutting device for diode processing is connected to 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0027] During use: by placing the diode for cutting pins into the card slot 9, and then starting the two electric push rods 13 to operate, the movable mold 10 can be driven to move downward. During the downward movement of the movable mold 10, the diode can be fixed by cooperating with the card slot 9 through the card hole 11 provided, thereby realizing the positioning and fixation of the diode. After fixation, the pin of the diode will be located outside the movable mold 10, and because there are multiple card slots 9, multiple diodes of the same size can be cut at the same time. When cutting is required, the slider 5 can be driven to move horizontally by the operation of the first motor 4, and when the slider 5 moves horizontally, it can synchronously drive the cutter 7 to move. When the cutter 7 moves to the position where the pin needs to be cut, the connection block 3 is driven downward by the operation of the two cylinders 2. When the connection block 3 moves downward, the cutter 7 can cut to the position where the pin needs to be cut, thereby completing the diode cutting process. When cutting a diode with a longer pin, the second motor 14 is started to drive the gear 15 to rotate counterclockwise. Because the gear 15 is engaged with the first tooth plate 16 and the second tooth plate 17, when the gear 15 rotates counterclockwise, the first tooth plate 16 and the second tooth plate 17 will move away from each other, thereby causing the first extension plate 18 and the second extension plate 19 to move away from each other synchronously. After moving away, the first extension plate 18 and the second extension plate 19 can support the longer pin, avoiding the situation where the cutting force causes the connection between the diode and the pin to be subjected to excessive force when the longer pin is not supported, thereby causing bending or breaking. This situation can be avoided by adjusting the position of the first extension plate 18 and the second extension plate 19. By providing a square hole, when the pin is cut, it will fall through the square hole into the collection box 22 for storage, which is convenient for subsequent unified processing.
