[0028] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings.

[0029] Refer to Figure 1 and Figure 2, the present invention provides a thyristor experiment monitoring device, including a conveying workbench 1 for conveying the thyristor main component 10. The conveying workbench 1 is provided with a plurality of monitoring stations. An equidistant discharging mechanism 2 is fixedly installed on the top of the conveying workbench 1.

The output ends of the plurality of ejecting mechanisms 6 respectively point to the gaps between the corresponding self-determination monitoring mechanisms 4 and the wiring mechanisms 5. A first laser sensor 7 is fixedly installed on the top of the conveying workbench 1. The first laser sensor 7 is arranged between the first workpiece positioning mechanism 3 and the second workpiece positioning mechanism 3 from far to near in the output direction of the conveying workbench 1. Second laser sensors 8 are fixedly installed at the plurality of monitoring stations of the conveying workbench 1. The first laser sensor 7 and the plurality of second laser sensors 8 are electrically connected to a PLC controller 9. The equidistant discharging mechanism 2, the workpiece positioning mechanism 3, the self-determination monitoring mechanism 4, the wiring mechanism 5, and the ejecting mechanism 6 are all connected to the PLC controller 9.

[0030] Referring to Figure 2 , 3 , the conveying workbench 1 includes a horizontal table 11, and a vertical plate 12 is arranged on the back of the horizontal table 11. The bottom of the horizontal table 11 and the vertical plate 12 are fixedly connected by a plurality of U-shaped connecting blocks 13. A gap for placing the thyristor main component 10 is arranged between the horizontal table 11 and the vertical plate 12. A secondary support table 15 is fixedly connected to the back of the horizontal table 11. A micro conveyor belt 14 is fixedly installed on the front and back of the vertical plate 12. The thyristor main component 10 is placed on the top of the micro conveyor belt 14 and the secondary support table 15. A gap for placing the pins of the thyristor main component 10 is arranged between the micro conveyor belt 14 and the secondary support table 15. The control motor of the micro conveyor belt 14 is electrically connected to the PLC controller 9 through a relay and a contactor. A plurality of notches are opened on the front of the vertical plate 12, and the plurality of second laser sensors 8 are respectively embedded in the plurality of notches. The wiring mechanism 5 is installed on the back of the vertical plate 12. The workpiece positioning mechanism 3 is fixedly installed on the top of the horizontal table 11. The ejecting mechanism 6 is fixedly installed on the bottom of the horizontal table 11. During use, the thyristor main component 10 is placed in the gap between the horizontal table 11 and the vertical plate 12, and the thyristor main component 10 is supported by the micro conveyor belt 14 and the secondary support table 15. The pins of the thyristor main component 10 pass through the gap between the micro conveyor belt 14 and the secondary support table 15. By running the micro conveyor belt 14, the effect of conveying the thyristor main component 10 can be achieved.

[0031] Referring to Figure 4, the wiring mechanism 5 includes a support connection platform 51. A first electric cylinder 52 is fixedly installed on the top of the support connection platform 51. The first electric cylinder 52 is electrically connected to the PLC controller 9 through a relay and a contactor. A first slider 53 is fixedly installed on the output shaft of the first electric cylinder 52. A chute penetrating through to the bottom is opened on the top of the support connection platform 51. The first slider 53 is slidably connected in the chute. A longitudinal push rod 54 is fixedly connected to the front of the first slider 53 at the bottom of the support connection platform 51. A wiring pressure head 56 is fixedly connected to the positive end of the longitudinal push rod 54. The wiring pressure head 56 is the output end of the wiring mechanism 5. A positioning sliding sleeve 55 is slidably sleeved on the side wall of the longitudinal push rod 54. The positioning sliding sleeve 55 is fixedly connected to the bottom of the support connection platform 51. During operation, the first electric cylinder 52 outputs to push the first slider 53 to slide, so that the longitudinal push rod 54 drives the wiring pressure head 56 to displace and push the pins of the thyristor main component 10 until the pins of the thyristor main component 10 are pressed tightly against the wiring end of the self-determination monitoring mechanism 4, thereby completing the wiring process.

[0032] Refer to Figure 5 , the wiring pressure head 56 is made of rubber material, and three V-shaped grooves 57 are opened on the front of the wiring pressure head 56. The rubber material has softness, which can avoid damaging the pins of the thyristor main component 10 and thus play a protective effect. By setting three V-shaped grooves 57, the three pins of the thyristor main component 10 can be respectively positioned and corrected to avoid position errors during wiring.

[0033] Refer to Figure 6 , the workpiece positioning mechanism 3 includes an L-shaped vertical plate 31. A second electric cylinder 32 is fixedly installed on the back of the L-shaped vertical plate 31. The second electric cylinder 32 is electrically connected to the PLC controller 9 through a relay and a contactor. The output end of the second electric cylinder 32 is fixedly connected with a cut-off material blocking piece 34 through a special-shaped connecting plate 33. The thickness of the cut-off material blocking piece 34 is less than the gap distance between the horizontal table 11 and the vertical plate 12. When the thyristor main component 10 is conveyed in the gap between the horizontal table 11 and the vertical plate 12, the special-shaped connecting plate 33 outputs to drive the cut-off material blocking piece 34 to move down and insert into the gap between the horizontal table 11 and the vertical plate 12. At this time, the thyristor main component 10 being conveyed can be intercepted by the cut-off material blocking piece 34, thereby achieving the positioning effect of the position of the thyristor main component 10.

[0034] Refer to Figure 7, the ejection mechanism 6 includes an L-shaped connecting plate 61. A first servo motor 62 is fixedly installed at the bottom of the L-shaped connecting plate 61. The first servo motor 62 is electrically connected to the PLC controller 9 through a relay and a contactor. A positioning rod 63 is fixedly connected to the top of the L-shaped connecting plate 61. A first reciprocating lead screw 64 is movably sleeved on the top of the L-shaped connecting plate 61. The output end of the first servo motor 62 is connected to the first reciprocating lead screw 64. A moving connecting plate 65 is threadedly sleeved on the side wall of the first reciprocating lead screw 64. The moving connecting plate 65 is slidably sleeved on the side wall of the positioning rod 63. The top of the moving connecting plate 65 is fixedly connected to a material supporting head 67 through a plurality of ejector pins 66. The material supporting head 67 is located at the output end of the ejection mechanism 6. A triangular block 68 is provided at the top end of the material supporting head 67. The triangular block 68 is fixedly connected to the front surface of the vertical plate 12. A notch is provided at the top of the auxiliary support table 15. The material supporting head 67 is embedded in the notch at the top of the auxiliary support table 15. During operation, the output of the first servo motor 62 drives the first reciprocating lead screw 64 to rotate. Under the influence of the thread structure, the moving connecting plate 65 can reciprocate. Under the connection effect of the ejector pins 66, the material supporting head 67 moves upward to lift the thyristor main component 10 until the thyristor main component 10 moves out of the gap between the horizontal table 11 and the vertical plate 12. Then, the thyristor main component 10 contacts the slope of the triangular block 68, causing the thyristor main component 10 to tilt forward and flip to the top of the horizontal table 11, thus completing the discharging process. When the moving connecting plate 65 moves to the topmost position, it moves back and forth under the action of the first reciprocating lead screw 64 until it resets.

[0035] Refer to Figure 2 , 7 , a slope groove is provided at the longitudinally aligned position of the top of the horizontal table 11 and the triangular block 68. A collection bucket is provided at the bottom of the horizontal table 11 below the slope groove. The thyristor main component 10 discharged to the top of the horizontal table 11 will fall into the slope groove and slide under the influence of the slope until it falls into the collection bucket. Thus, the unqualified thyristor main components 10 can be collected uniformly.

[0036] Refer to Figure 8, the self-determination monitoring mechanism 4 includes a housing 41. A through groove penetrating to the interior is formed in the back of the housing 41. A protective block 42 is fixedly connected inside the through groove. A gate connection terminal 43, an anode connection terminal 44, and a cathode connection terminal 45 are fixedly connected inside the protective block 42. Both ends of the gate connection terminal 43, the anode connection terminal 44, and the cathode connection terminal 45 penetrate through the front and back surfaces of the protective block 42 respectively. An indicator light 46, a manual switch 47, and a relay element 48 are fixedly installed inside the housing 41. The light-emitting end of the indicator light 46 penetrates through the bottom of the housing 41, and the control end of the manual switch 47 penetrates through the bottom of the housing 41. A main power battery 410 and a secondary power battery 411 are fixedly installed on the front of the housing 41. A cover 412 is fixedly installed at the bottom of the housing 41. The light-emitting end of the indicator light 46 is located inside the cover 412. The main power battery 410 is electrically connected to the manual switch 47 through an electric wire. The manual switch 47 is electrically connected to the back end of the anode connection terminal 44 through an electric wire. The back end of the cathode connection terminal 45 is electrically connected to the indicator light 46 through an electric wire. The indicator light 46 is electrically connected to the main power battery 410 through an electric wire. The secondary power battery 411 is electrically connected to the relay element 48 through an electric wire. The relay element 48 is electrically connected to the back end of the gate connection terminal 43 through an electric wire. The back end of the anode connection terminal 44 is electrically connected to a resistance element 49 through an electric wire. The resistance element 49 is electrically connected to the secondary power battery 411 through an electric wire. The relay element 48 and the photosensor 413 are electrically connected to the PLC controller 9. Before the self-determination monitoring mechanism 4 works, it is necessary to ensure that the manual switch 47 is in the open state. The three pins of the thyristor main component 10 are pressed against the back ends of the gate connection terminal 43, the anode connection terminal 44, and the cathode connection terminal 45 to form a closed circuit. After the relay element 48 is controlled by the PLC controller 9 to open and then close, the thyristor main component 10 is turned on. At this time, if the indicator light 46 is in the lit state, the thyristor main component 10 is qualified for monitoring. If the indicator light 46 is not lit, the thyristor main component 10 is unqualified. The photosensor 413 can sense the state of the indicator light 46 for determination and send a signal to the PLC controller 9. When the PLC controller 9 controls the ejection mechanism 6 to operate, it can accurately control the ejection mechanism 6 at a certain monitoring station to operate and screen out unqualified products.

[0037] Refer to Figure 9, the equidistant discharging mechanism 2 includes a slide rail 21, inside which a moving block 22 is slidably sleeved. At the top of the slide rail 21, two end plates 24 are fixedly connected. Inside the two end plates 24, a second reciprocating lead screw 25 is movably sleeved. The moving block 22 is threadedly sleeved on the side wall of the second reciprocating lead screw 25. On the front of one of the end plates 24, a second servo motor 26 is fixedly installed. The output end of the second servo motor 26 penetrates through this end plate 24 and is connected to the second reciprocating lead screw 25. The back of the moving block 22 is connected to a material blocking press head 23 through a connecting rod. A rubber soft pad is arranged on the back of the material blocking press head 23. The back end of the material blocking press head 23 is closely attached to a thyristor main component 10. The second servo motor 26 is electrically connected to the PLC controller 9 through a relay and a contactor. By closely attaching a thyristor main component 10 with the material blocking press head 23, the interception effect on a number of conveyed thyristor main components 10 can be achieved. By controlling the single output of the second servo motor 26 through the PLC controller 9, the moving block 22 can move back and forth, that is, the pressing effect of the material blocking press head 23 on a thyristor main component 10 can be removed. At this time, the thyristor main component 10 is output through the conveying workbench 1. After the moving block 22 moves back and forth and resets, it can drive the material blocking press head 23 to press and intercept the second thyristor main component 10. By controlling the interval time period of each output of the second servo motor 26 through the PLC controller 9, the equidistant feeding effect of the thyristor main components 10 can be achieved. By monitoring the number of work positions of the conveying workbench 1, the output times of the second servo motor 26 in each operation cycle of the equidistant discharging mechanism 2 can be set.

[0038] The working principle of the present invention: By placing a number of thyristor main components 10 at the conveying end of the conveying workbench 1, the conveying workbench 1 moves a number of thyristor main components 10 towards the monitored work positions of the conveying workbench 1. During this process, it is necessary to pass through the equidistant discharging mechanism 2. The equidistant discharging mechanism 2 intercepts the moving thyristor main components 10 and discharges them at equal intervals. At the same time, it is necessary to control the discharging quantity to match the number of monitored work positions. The distance between multiple equidistantly discharged thyristor main components 10 is approximately matched with the distance between multiple monitored work positions. When the first discharged thyristor main component 10 approaches the last work position, the first laser sensor 7 senses the presence of material and transmits a signal to the PLC controller 9. The PLC controller 9 controls the simultaneous operation and output of multiple workpiece positioning mechanisms 3. Through the multiple workpiece positioning mechanisms 3, the intercepted effect of multiple discharged thyristor main components 10 can be achieved. Since the thyristor main components 10 are in contact with the output ends of the workpiece positioning mechanisms 3, multiple thyristor main components 10 can be positioned at the monitored work positions.

[0039] At this time, multiple thyristor main components 10 to be monitored respectively block multiple second laser sensors 8, so that multiple second laser sensors 8 all sense the presence of materials, and transmit the material presence signals to the PLC controller 9. At this time, the PLC controller 9 controls the conveying workbench 1 to stop conveying, the wiring mechanism 5 to operate to output the wiring of the pins of the thyristor main component 10, and the self-determination monitoring mechanism 4 to operate to monitor and determine the product in sequence;

[0040] On this basis, according to the monitoring and determination time of the self-determination monitoring mechanism 4, after the PLC controller 9 controls the self-determination monitoring mechanism 4 to operate for a certain period of time, it then controls the wiring mechanism 5 to operate to retract and remove the wiring of the thyristor main component 10 in sequence. Then, it controls the ejecting mechanism 6 to operate to output according to the determination result corresponding to the self-determination monitoring mechanism 4 (when the self-determination monitoring mechanism 4 determines that the product is unqualified, the ejecting mechanism 6 outputs; when the self-determination monitoring mechanism 4 determines that the product is qualified, the ejecting mechanism 6 does not operate). The unqualified products are ejected to the top of the conveying workbench 1 through the ejecting mechanism 6. Then, it controls the workpiece positioning mechanism 3 to operate to retract and remove the interception of the thyristor main component 10. Then, it controls the conveying workbench 1 to start conveying. When the monitored qualified thyristor main components 10 are conveyed and discharged by the conveying workbench 1, the product classification is automatically completed. At this time, the product monitoring for one cycle is completed, and at the same time, the product monitoring for the next cycle is connected and circulated.
