Description

Technical Field

[0001] The utility model relates to the technical field of diode processing, in particular to a diode shaping machine. Background Art

[0002] TVS diode, also known as transient voltage suppression diode, is a high-efficiency protection device. Its appearance is mainly composed of a cylindrical shell and pins at both ends. For example, patent number CN218730902U discloses a heat dissipation TVS diode, which is mainly used to protect precision components in electronic circuits from damage by various surge pulses. It is usually connected in parallel with the protected device. Under normal working conditions, it presents a high impedance state. However, when the instantaneous voltage exceeds its breakdown voltage, the TVS diode will quickly change to a low impedance state, providing a channel for the instantaneous current, thereby shunting the current and limiting the voltage at both ends of the protected component.

[0003] At present, the diode pins need to be bent in some cases. When the distance between the installation holes is small, in order to better adapt to the hole distance on the circuit board, the diode may need to be installed vertically. At this time, the pins need to be bent and shaped. For example, patent No. CN216858051U discloses a diode shaping machine. The electric telescopic rod is started to push the U-shaped pressing block downward, so that the two bottoms of the U-shaped pressing block simultaneously press the welding columns of multiple diodes into the inner sides of the two rectangular holes, thereby completing the batch shaping of the diodes without bending the welding columns of the diodes one by one.

[0004] However, the above solution has certain shortcomings. The diode is placed directly on the support pad, and there is no good positioning and limiting mechanism to fix the position. During shaping, the position of the diode may not be correct, or it may shake during the bending process, resulting in the production accuracy cannot be guaranteed.

[0005] Therefore, in view of this, the applicant has studied and improved the existing structural deficiencies and proposed a diode shaping machine to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a diode shaping machine to solve the problem that the diodes in the existing comparative literature proposed in the above background technology do not have good positioning and limiting, and the position of the diodes may be incorrect during shaping, or shaking may occur during the bending process, thereby resulting in the production accuracy cannot be guaranteed.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a diode shaping machine, comprising a machine base, an inner groove is provided in the middle position of the machine base, U-shaped frames are connected on both sides of the machine base, a lifting plate is installed on the U-shaped frame through a hydraulic rod, two bending plates are fixed at the bottom of the lifting plate, and a limited feeding mechanism is installed in the inner groove of the machine base, the limited feeding mechanism includes two transverse plates fixed in the inner wall of the machine base, a feeding platform is slidably connected to the outside of the transverse plate, six limiting grooves are provided on the feeding platform, diodes are placed in the limiting grooves, a tooth path is provided at the bottom of the feeding platform, a gear is meshed with the tooth path, one end of the gear is rotatably connected to the inner wall of the machine base, and the gear is connected to the motor shaft, and the motor is installed in the inner cavity of the machine base.

[0008] Preferably, two electromagnetic latches are installed on one side of the loading platform, and the surface of the horizontal plate is provided with six locking holes for inserting the electromagnetic latches, and the spacing between adjacent locking holes is the same as the spacing between the limiting grooves.

[0009] Preferably, the machine base is provided with two bending openings in the inner groove, and the bending openings are located below the bending plate.

[0010] Preferably, four buffer springs are connected between the top surface of the lifting plate and the U-shaped frame, and the buffer springs are stretched and deformed when the lifting plate descends.

[0011] Preferably, two guide slide rods pass through the lifting plate, and the top end of the guide slide rod is connected to the lifting plate with a limiting spring, and an arc-surface clamping plate is fixed to the bottom of the guide slide rod. When the arc-surface clamping plate is in contact with the diode housing, the bending plate contacts the welded pins at both ends of the diode.

[0012] Preferably, a layer of soft pad is bonded to the bottom of the curved splint, and the soft pad is made of rubber.

[0013] Preferably, the U-shaped frame is provided with an opening for the guide slide bar to pass through, and the bottom surface of the lifting plate is provided with a notch, and the notch corresponds to the position of the curved clamping plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model designs a limited feeding mechanism, so that when bending is performed, multiple diodes are placed in six limited grooves on the feeding table, and then the motor is started to drive the gear to rotate a certain angle to automatically close, so that the feeding table slides through the cross plate, and then the hydraulic rod is started to lower the lifting plate, and the bending plate can bend the pins at two places, and then the operation is cyclically performed until all the processing is completed and the feeding table is reset. In this way, not only batch shaping processing can be realized, but multiple diodes are respectively located in their respective limited grooves and will not rotate or deviate during processing, thereby effectively improving the processing stability and improving the processing accuracy.

[0016] When the utility model is bending, the arc-surface clamping plate contacts the diode together with the bending plate. As the bending plate continues to descend, the guide slide bar slides on the lifting plate and stretches the limit spring. The limit spring uses elastic force to make the arc-surface clamping plate press and fix the diode shell. The soft pad can reduce the extrusion force of the contact between the two, thereby further improving the stability of the diode and preventing it from rotating, thereby improving the processing accuracy.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 8 As shown, a diode shaping machine includes a machine base 1, an inner groove 12 is provided in the middle position of the machine base 1, U-shaped frames 2 are connected to the two sides of the machine base 1, a lifting plate 22 is installed on the U-shaped frame 2 through a hydraulic rod 21, two bending plates 23 are fixed at the bottom of the lifting plate 22, a limited feeding mechanism 3 is installed in the inner groove 12 of the machine base 1, the limited feeding mechanism 3 includes two transverse plates 31 fixed in the inner wall of the machine base 1, a feeding platform 32 is slidably connected to the outside of the transverse plate 31, six limiting grooves are provided on the feeding platform 32, diodes 4 are placed in the limiting grooves, a tooth path 33 is provided at the bottom of the feeding platform 32, the tooth path 33 is meshed with a gear 34, one end of the gear 34 is rotatably connected to the inner wall of the machine base 1, and the gear 34 is connected to the shaft of a motor 35, and the motor 35 is installed in the inner cavity of the machine base 1.

[0028] By designing a limited feeding mechanism 3, multiple diodes 4 are placed in the six limited grooves on the feeding table 32 during bending. As can be seen from the figure, the pins on both sides of the diode 4 fit into the limited grooves, and then the motor 35 is started to drive the gear 34 to rotate a certain angle and automatically close. The gear 34 meshes with the tooth path 33, so that the feeding table 32 slides through the cross plate 31, and through the intelligent controller, the diode 4 can be transported to the bottom of the U-shaped frame 2 each time, and then the hydraulic rod 21 is started to lower the lifting plate 22, and the bending plate 23 can bend the pins at two places, and then the operation is cyclically performed until all the processing is completed and the feeding table 32 is reset. In this way, not only batch shaping processing can be realized, but also multiple diodes 4 are respectively located in their respective limited grooves and will not rotate or deviate during processing, thereby effectively improving the processing stability and processing accuracy.

[0029] Two electromagnetic latches 36 are installed on one side of the loading platform 32, and six locking holes 37 for the electromagnetic latches 36 to be inserted are provided on the surface of the horizontal plate 31, and the spacing between adjacent locking holes 37 is the same as the spacing between the limiting grooves.

[0030] In this way, each time the diode 4 is transported to the processing position, do not start the hydraulic rod 21 first. You can start the electromagnetic latch 36 first to insert its locking block into the locking hole 37 to position the loading platform 32, thereby further improving the stability of the bending and avoiding loosening due to a small gap between the gear 34 tooth track 33. Note that through the spacing design, each time the diode 4 is transported to the processing position, the electromagnetic latch 36 will correspond to the position of a locking hole 37.

[0031] The base 1 is provided with two bending openings 11 in the inner groove 12 , and the bending openings are located below the bending plate 23 .

[0032] The design of the bending opening 11 can facilitate the rotation of the pins at both ends of the diode 4 for shaping operations, which is very practical. It should be noted that after the pins are bent, they move in the space between the inner groove 12 and the loading platform 32 .

[0033] Four buffer springs 24 are connected between the top surface of the lifting plate 22 and the U-shaped frame 2 , and the buffer springs 24 are stretched and deformed when the lifting plate 22 descends.

[0034] The buffer spring 24 can provide buffering when the lifting plate 22 is lowered and bent, so as to avoid the pins from having a large collision with the bending plate 23 due to the lowering speed being too fast, resulting in cracks or scratches, thereby playing a good protective role.

[0035] Two guide slide bars 25 pass through the lifting plate 22, and the top ends of the guide slide bars 25 are connected to the lifting plate 22 by limit springs 26. An arc-surface clamp 27 is fixed to the bottom of the guide slide bar 25. When the arc-surface clamp 27 is in contact with the outer shell of the diode 4, the bending plate 23 contacts the welded pins at both ends of the diode 4. A layer of soft pad 28 is bonded to the bottom of the arc-surface clamp 27, and the soft pad 28 is made of rubber. An opening for the guide slide bar 25 to pass through is provided on the U-shaped frame 2, and a recess is provided on the bottom surface of the lifting plate 22, and the recess corresponds to the position of the arc-surface clamp 27.

[0036] Through the above structural design, when bending, the arc-surface clamping plate 27 contacts the diode 4 together with the bending plate 23. As the bending plate 23 continues to descend, the guide slide bar 25 slides on the lifting plate 22 and stretches the limit spring 26. The limit spring 26 uses elastic force to make the arc-surface clamping plate 27 press and fix the diode 4 tube shell. The soft pad 28 can reduce the extrusion force of the contact between the two, and then further improve the stability of the diode 4 to prevent it from rotating, thereby improving the processing accuracy. Finally, when the clamping plate 27 descends to the lowest end to complete the bending, the arc-surface clamping plate 27 will enter the recess on the bottom surface of the lifting plate 22, and the guide slide bar 25 passes through the opening of the U-shaped frame 2.

[0037] Working principle: When bending, multiple diodes 4 are placed in the six limit grooves on the loading platform 32. As can be seen from the figure, the diodes 4 and the pins on both sides fit into the limit grooves. Then the motor 35 is started to drive the gear 34 to rotate a certain angle and automatically close. The gear 34 meshes with the tooth path 33, so that the loading platform 32 slides through the cross plate 31. Through the intelligent controller, the diodes 4 can be transported to the bottom of the U-shaped frame 2 every time. Then the electromagnetic latch 36 is started to insert its lock block into the locking hole 37 to position the loading platform 32. Then the hydraulic rod 21 is started to make the lifting plate 22 move down. The bending plate 23 bends the pins at two places, and in the bending process, the arc-surface clamping plate 27 contacts the diode 4 together with the bending plate 23. As the bending plate 23 continues to descend, the guide slide bar 25 slides on the lifting plate 22 and stretches the limit spring 26. The limit spring 26 uses the elastic force to make the arc-surface clamping plate 27 press and fix the diode 4 shell. The cushion 28 can reduce the extrusion force of the contact between the two, and then further improve the stability of the diode 4. The operation is then circulated until all the processing is completed, the loading table 32 is reset, and the diode 4 is taken out to proceed with the next batch of processing.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
