When the semiconductor diode reaches the tail end of the conveyor track and leaves the conveyor track, it just falls into the opening of a certain limit seat being transported by the conveyor belt. As the conveyor belt is transported, the pins at both ends of the semiconductor diode are driven by the limit fan blades to enter the placement groove, and the pins pass through the pin limit groove; A placement groove 205 for accommodating a diode is provided on the top of the limiting seat 201, and an opening 208 is provided on the left and right side walls of the placement groove 205, and a pin limiting groove 207 is provided on the side wall of the opening 208 close to the conveying track 4, and a slot 206 with a stopper 203 slidably connected inside is provided at the bottom of the placement groove 205, and an arc-shaped contact block 204 is fixedly installed at the bottom of the stopper 203, and a pressing block 202 cooperating with the arc-shaped contact block 204 is fixedly installed on both sides of the conveyor belt 8 and on the outer wall of the supporting shell 7, respectively.

The servo motor drives the bidirectional screw to rotate, further clamping the two limit blocks inward and contacting the two sides of the PN junction, so that it moves to the middle position in the opening and aligns with the placement slot. When the two limit blocks return to their positions and the limit seat continues to move, the pin contacts the limit fan blade. In the process of pushing the limit fan blade to rotate, it can smoothly enter the placement slot under the reaction of the driving force.

[0021] The above-mentioned bending mechanism includes: a first connecting frame 108, a bottom pressure plate 107, a driving bin 101 and a pressing knife 113 located inside the driving bin 101. The first connecting frame 108 installed on the outer wall of the above-mentioned supporting shell 7 is located below the above-mentioned driving bin 101, and the above-mentioned bottom pressure plate 107 is fixedly installed on the top of the above-mentioned first connecting frame 108. This bottom pressure plate 107 is located below the diode pin. The above-mentioned driving bin 101 is used to drive the pressing knife 113 to press down and bend the diode pin along the side wall of the bottom pressure plate 107.

[0022] A first slide groove 102 is provided on one side of the driving bin 101 relative to the first connecting frame 108, a second slide groove 114 is provided inside the first slide groove 102 and on the outer wall of the pressing knife 113, a first support plate 103 is fixedly installed above the second slide groove 114, a third support plate 111 is movably engaged in the second slide groove 114, a hydraulic rod 110 is provided between the first support plate 103 and the third support plate 111, a movable end of the hydraulic rod 110 is fixedly connected to the third support plate 111, a pressing plate 109 cooperating with the bottom pressing plate 107 is provided below the third support plate 111, and a plurality of pressing rods 112 are provided between the pressing plate 109 and the third support plate 111; While the diode is initially limited by the groove of the conveyor belt, the diode is driven to move. When it moves to the bottom of the pressure plate, the pins of several diodes are simultaneously located between the pressure plate and the bottom pressure plate. The pressure cutter is driven downward by the driving bin and the pressure plate is driven downward by the hydraulic rod. During the downward movement, the pressure plate fixes the diode pins in advance, and then the diode pins are bent along the side wall of the bottom pressure plate by the pressure cutter.

[0024] When the pressing knife and the bottom pressure plate are used to clamp and bend the pins, during the downward movement of the pressing knife, the pressing rod is driven by the first support plate to press the pressure plate located on the outer wall of the driving bin, and the spring is stretched until the pressure plate is pressed on the pin located on the bottom pressure plate to press and fix it. At this time, the pressing knife does not touch the pin position. After the pressure plate is pressed into place, the hydraulic rod simultaneously releases pressure, and the pressing knife continues to press down to bend, thereby achieving correction before bending and pressing during bending, ensuring bending accuracy and bending effect.

[0025] A second slide 310 is sleeved on the outer wall of the support shaft 312 , and one end of the second slide 310 away from the support shaft 312 is fixedly connected to the first slide 303 .

[0029] The conveyor track 4 is located above the conveyor belt 8 .

[0030] Embodiment 2: A semiconductor diode forming device comprises: a base 5, a conveying track 4 for conveying diodes is arranged on one side of the base 5, a supporting shell 7 is fixedly installed on the top of the base 5, and a conveying belt 8 with a plurality of limit seats 201 is arranged on the outer wall of the supporting shell 7, the limit seats 201 are arranged at equal intervals along the length direction of the conveying belt 8, and a bending mechanism is arranged on both sides of the conveying belt 8; A placement groove 205 for accommodating a diode is provided on the top of the limiting seat 201, and an opening 208 is provided on the left and right side walls of the placement groove 205, and a pin limiting groove 207 is provided on the side wall of the opening 208 close to the conveying track 4, and a slot 206 with a stopper 203 slidably connected inside is provided at the bottom of the placement groove 205, and an arc-shaped contact block 204 is fixedly installed at the bottom of the stopper 203, and a pressing block 202 cooperating with the arc-shaped contact block 204 is fixedly installed on both sides of the conveyor belt 8 and on the outer wall of the supporting shell 7, respectively. When the limiting seat 201 is located above the pressing block 202, the pressing block 202 can lift the stopper 203, so that the stopper 203 closes the opening of the pin limiting groove 207; During the transmission process of the conveyor belt, the semiconductor diode located in the placement groove of the limit seat will push the limit fan blade, and the limit fan blade has a reaction force on the semiconductor diode, thereby pushing the semiconductor diode into the pin limit groove to achieve the position limitation of the semiconductor diode. As the limit seat continues to move, the arc contact block moves along the pressing block, thereby lifting the stop block and closing the pin limit groove, thereby avoiding the situation where the diode rolls out of the pin limit groove, greatly improving the position accuracy of the diode, and avoiding the situation where the position of the diode is offset during the transmission process, resulting in different bending degrees of the pins at both ends, thereby improving the processing quality; A bearing seat 301 is symmetrically arranged at the bottom of one end of the conveying track 4 close to the conveyor belt 8, and a sliding rod 302 and a bidirectional screw rod 304 are arranged between the two bearing seats 301, the bidirectional screw rod 304 located below the sliding rod 302 is rotatably connected to the bearing seat 301, and two nuts 306 are arranged on the outer wall of the bidirectional screw rod 304 and symmetrically with respect to the conveyor belt 8, and the nut 306 is fixedly connected with a first sliding rack 303 sleeved on the sliding rod 302, and a limiting folding block 309 corresponding to the placement groove 205 is installed at one end of the first sliding rack 303 away from the bidirectional screw rod 304, and a support shaft 312 on which a limiting fan blade 307 is rotatably installed is located between the pressure block 202 and the limiting folding block 309 and fixedly installed on the outer wall of the supporting shell 7, and the two limiting fan blades 307 symmetrically arranged with respect to the conveyor belt 8 are in contact with the diode pin push-up, thereby pushing the diode pin from the opening 208 into the pin limiting groove 207; Driving the bidirectional lead screw to rotate forward drives the two first slides to move synchronously toward each other, so that the two limiting folding blocks moving synchronously push the semiconductor diode to the middle position of the placement slot. Under this structure, the semiconductor diode can be effectively prevented from being dislocated. Then, the arc contact block contacts the pressure block. When it contacts the top of the pressure block, the stop block is lifted up as a resistance to prevent the semiconductor diode from shifting. Multiple semiconductor diodes can be limited at the same time through the longer pressure block, so that the bending mechanism can be used to simultaneously bend multiple semiconductor diodes. Under this structure, multiple semiconductor diodes are limited at the same time and their stability is guaranteed, thereby realizing the synchronous forming processing of multiple semiconductor diodes, reducing the reciprocating frequency of the bending mechanism, and playing a role in energy saving and extending the service life of the machinery.

[0033] A second slide 310 is sleeved on the outer wall of the support shaft 312 , and one end of the second slide 310 away from the support shaft 312 is fixedly connected to the first slide 303 .

[0034] A guide groove 6 for receiving the diode is provided at the rear end of the conveyor belt 8 in the transmission direction and on one side of the base 5 .

[0035] The pressing block 202 is in a trapezoidal shape, and a guiding inclined surface 9 is formed at both ends of the upper portion of the pressing block 202 to match the arc-shaped contact block 204 .

[0036] The driving compartment 101 and the base 5 are fixedly connected via a supporting frame 10 .

[0037] A driving mechanism for driving the conveyor belt 8 is disposed inside the supporting shell 7 .

[0038] The working principle is: During the processing, the semiconductor diode is transported along the conveyor track to the conveyor belt position. When the semiconductor diode reaches the tail end of the conveyor track and leaves the conveyor track, it just falls into the opening of a certain limit seat being transported by the conveyor belt. As the conveyor belt is transported, the pins at both ends of the semiconductor diode are driven by the limit fan blades to enter the placement groove, and the pins pass through the pin limit groove; Among them, when the semiconductor diode falls into the opening, there may be a certain displacement, resulting in failure to smoothly enter the placement groove. The servo motor drives the bidirectional screw to rotate, further clamping the two limit folding blocks inward, contacting the two sides of the PN junction, so that it moves to the middle position in the opening and aligns with the placement groove. When the two limit folding blocks return to their positions and the limit seat continues to move, the pin contacts the limit fan blade. In the process of pushing the limit fan blade to rotate, under the reaction of the driving force, it can smoothly enter the placement groove. Under this structure, the semiconductor diode can be effectively prevented from being dislocated. Then, the arc contact block contacts the pressing block. When it contacts the top of the pressing block, the stopper is lifted as a stopper to prevent the semiconductor diode from shifting. Multiple semiconductor diodes can be simultaneously limited by a longer pressing block, so that the bending mechanism can be used to simultaneously bend multiple semiconductor diodes. Under this structure, the simultaneous limiting of multiple semiconductor diodes is achieved, and their stability is guaranteed, the synchronous forming processing of multiple semiconductor diodes is achieved, the reciprocating frequency of the bending mechanism is reduced, and the effect of energy saving and extending the service life of the machine is achieved. When the pressing knife and the bottom pressure plate are used to clamp and bend the pins, during the downward movement of the pressing knife, the pressing rod is driven by the first support plate to press the pressure plate located on the outer wall of the driving bin, and the spring is stretched until the pressure plate is pressed on the pin located on the bottom pressure plate to press and fix it. At this time, the pressing knife does not touch the pin position. After the pressure plate is pressed into place, the hydraulic rod simultaneously releases pressure, and the pressing knife continues to press down to bend, thereby achieving correction before bending and pressing during bending, ensuring bending accuracy and bending effect.

[0039] When the semiconductor diode forming device is used, the diode is transmitted on the conveying track, and the diode is transferred from the conveying track to the conveyor belt, and the diode falls into the placement groove of the limit seat, and the pin of the diode can be exposed from the opening, and the two first slides are driven to move synchronously toward each other by driving the bidirectional lead screw to rotate forward, so that the two synchronously moving limit folding blocks push the semiconductor diode to the middle position of the placement groove, and during the transmission process of the conveyor belt, the semiconductor diode located in the placement groove of the limit seat will push the limit fan blade, and the limit fan blade has a reaction force on the semiconductor diode, thereby pushing the semiconductor diode into the pin limit groove to achieve the position limitation of the semiconductor diode, and the limit seat continues to move, so that the arc contact block moves along the pressure block, thereby lifting the block and closing the pin limit groove, thereby avoiding the situation that the diode rolls out of the pin limit groove, greatly improving the position accuracy of the diode, and avoiding the situation that the position offset of the diode during the transmission process causes the pins at both ends to be bent to different degrees, thereby improving the processing quality; In addition, while the diode is initially limited by the groove of the conveyor belt, it drives the diode to move. When it moves to the bottom of the pressure plate, the pins of several diodes are simultaneously located between the pressure plate and the bottom pressure plate. The pressure cutter is driven downward by the driving bin and the pressure plate is driven downward by the hydraulic rod. During the downward movement, the pressure plate fixes the diode pins in advance, and then the diode pins are bent along the side wall of the bottom pressure plate by the pressure cutter. This not only improves the position accuracy of the pins and improves the processing effect, but also allows multiple diodes to be bent at the same time, greatly improving the overall processing efficiency.
