DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] Reference Figures 1-10 ​The embodiment provides a technical scheme: a diode quality detection equipment, the diode includes a body 500, one end of the upper surface of the body 500 has a gap 510, the other end has a pin 520, the detection equipment includes a machine body 400, the machine body 400 includes a workbench 410, the workbench 410 is rotationally connected with a rotating disc 430, the rotating disc 430 is provided with a polarity correction mechanism 100, the polarity correction mechanism 100 includes a placing table 110, the placing table 110 is rotationally connected with a cylinder 120, a rectangular hole is formed in the middle part of the cylinder 120, the body 500 is inserted into the rectangular hole, one end of the placing table 110 towards the center of the rotating disc 430 is slidingly connected with a rectangular piston cylinder 142, the rectangular piston cylinder 142 is slidingly connected with a rectangular piston rod 143, the placing table 110 is fixedly connected with a circular piston cylinder 150 in communication with the rectangular piston cylinder 142, the circular piston cylinder 150 is slidingly connected with a circular piston rod 152, the output end of the circular piston rod 152 is slidingly connected with a bevel gear ring 130, and the bevel gear ring 130 is slidingly connected to the cylinder 120; the workbench 410 is connected with a detection table 420, and the bottom of the detection table 420 is connected with an arc-shaped rack 190, when the polarity of the body 500 is reversed, the rectangular piston cylinder 142 slides towards the body 500, the rectangular piston rod 143 abuts against the body 500, so that the circular piston rod 152 is elongated and pushes the bevel gear ring 130 to slide in the cylinder 120, so that when the rotating disc 430 rotates, the bevel gear ring 130 can roll on the arc-shaped rack 190, and the body 500 is turned by one hundred and eighty degrees.

[0033] The rotating disc 430 is driven by a servo motor, according to the number of the placing tables 110 on the rotating disc 430, the servo motor drives the rotating disc 430 to rotate by an angle of the included angle between adjacent two placing tables 110 and the center line of the rotating disc 430 and then pause, so that the diodes on the placing tables 110 can be detected;

[0034] After the rotating disc 430 stops rotating, the diode is placed on the placing table 110, so that the body 500 of the diode is inserted into the cylinder 120, the rotating disc 430 continues to rotate, and in the subsequent rotating process of the rotating disc 430, the rectangular piston cylinder 142 slides towards the cylinder 120, for example Figure 3 and Figure 8As shown, if the polarity of the diode is not reversed, the notch 510 is in the upward state, at this time the rectangular piston barrel 142 drives the rectangular piston rod 143 to move towards the diode, at this time the end of the rectangular piston rod 143 moves to the position of the notch 510 without contacting the body 500, so that the subsequent flip action will not be triggered, if the polarity of the diode is reversed, the notch 510 is downward, at this time the rectangular piston barrel 142 moves to drive the rectangular piston rod 143 to move, the rectangular piston rod 143 abuts on the body 500, at this time the rectangular piston barrel 142 continues to move, then the rectangular piston rod 143 slides into the inside of the rectangular piston barrel 142, the air in the rectangular piston barrel 142 is transmitted to the inside of the circular piston barrel 150 through the air pipe 151, so that the circular piston rod 152 is elongated and can push the bevel gear ring 130 to slide in the cylinder 120, at this time the bevel gear ring 130 shortens the distance from the center of the turntable 430, and then the turntable 430 drives the placement table 110 to continue to move, at this time the bevel gear ring 130 can mesh with the arc-shaped rack 190, so that after the bevel gear ring 130 rolls over the arc-shaped rack 190, the bevel gear ring 130 drives the cylinder 120 to flip one hundred and eighty degrees, so that the polarity of the diode is corrected, ensuring the accuracy of the later electrical detection of the diode.

[0035] When the bevel gear ring 130 does not slide towards the direction of the turntable 430, the turntable 430 drives the bevel gear ring 130 to move to the position of the arc-shaped rack 190, at this time there is a gap between the bevel gear ring 130 and the arc-shaped rack 190 and they will not mesh, so that at this time the cylinder 120 will not be flipped.

[0036] The polarity correction mechanism 100 further comprises a sliding seat 140 radially sliding on the turntable 430, the rectangular piston barrel 142 is fixedly connected to the top of the sliding seat 140, the side of the sliding seat 140 is fixedly connected with a protruding block 141, the sliding seat 140 is connected with the spring 160 between the sliding seat 140 and the placement table 110, the lower surface of the detection table 420 is fixedly connected with an arc-shaped baffle 170 and a wedge block 180, when the protruding block 141 contacts the wedge block 180, one end of the body 500 close to the pin 520 contacts the inner surface of the arc-shaped baffle 170, so that the body 500 cannot slide relative to the cylinder 120.

[0037] When the turntable 430 drives the placement table 110 to revolve, the inner surface of the arc-shaped baffle 170 abuts on one end of the body 500 towards the pin 520, at this time the arc-shaped baffle 170 blocks the diode, so that the diode will not slide out of the cylinder 120, at the same time when the turntable 430 rotates, the protruding block 141 can contact the wedge block 180, so that when the protruding block 141 slides along the inclined surface of the wedge block 180, it can drive the sliding seat 140 to move the rectangular piston barrel 142 towards the cylinder 120, so that if the rectangular piston rod 143 abuts on the body 500, it will not push the body 500 out of the cylinder 120.

[0038] The first electric push rod 131 is fixedly connected to the workbench 410, and after the placement table 110 is driven by the rotating disc 430 to move past the arc-shaped rack 190, the cylinder 120 is opposite to the first electric push rod 131, so that the first electric push rod 131 can push the bevel gear ring 130 to reset when being elongated.

[0039] The rotating disc 430 continues to rotate to make the placement table 110 move past the arc-shaped rack 190 and then move to a position opposite to the first electric push rod 131, and then the rotating disc 430 pauses, at this time, the first electric push rod 131 is elongated and pushes the bevel gear ring 130 to slide to the original position, so that the circular piston rod 152 is pressed back into the circular piston cylinder 150, at this time, the air in the circular piston cylinder 150 is transferred to the rectangular piston cylinder 142, so that the rectangular piston rod 143 resets, facilitating subsequent correction of the polarity of the diode.

[0040] The arc-shaped rack 190 is provided with arc-shaped strip protrusions with the same arc as the arc-shaped rack 190 on both sides in the extension direction, and the bevel gear ring 130 is between the two arc-shaped strip protrusions when the bevel gear ring 130 is engaged with the arc-shaped rack 190, so as to ensure stable engagement of the bevel gear ring 130 with the arc-shaped rack 190.

[0041] The circular piston rod 152 is provided with two ends, and the two circular piston rods 152 are symmetrically arranged on the placement table 110, and the ends of the two circular piston rods 152 are fixedly connected with sliding blocks 153, and the bevel gear ring 130 is provided with an annular sliding groove matched with the two sliding blocks 153.

[0042] The two circular piston cylinders 150 and the two corresponding circular piston rods 152 are arranged, so that the bevel gear ring 130 can be subjected to balanced pushing force, and the sliding blocks 153 are arranged, so that the bevel gear ring 130 can rotate relative to the circular piston rod 152, and the circular piston rod 152 is not separated from the bevel gear ring 130.

[0043] Two spherical protrusions 121 are symmetrically arranged on one end face of the cylinder 120, and a spherical groove matched with the two spherical protrusions 121 is arranged on the placement table 110.

[0044] The spherical protrusions 121 can be elastically deformed, so that the cylinder 120 can rotate, and after rotating one hundred and eighty degrees, the other spherical protrusion 121 is clamped in the spherical groove on the placement table 110, completing the positioning of the cylinder 120.

[0045] In addition, the cylinder 120 is drilled by a ball head drill, the spherical protrusion 121 is replaced by a ball, the ball, a return spring and a plug are inserted into the drilled hole, when the cylinder 120 rotates, the ball is retracted to the end face of the cylinder 120, and after the cylinder 120 rotates one hundred and eighty degrees, the other ball is clamped in the spherical groove on the placement table 110, completing the positioning of the cylinder 120.

[0046] The shape detection mechanism 200 is used for detecting whether the pin 520 is bent, and comprises a swing rod 240, and a detection rake 241 fixedly connected to an end of the swing rod 240. When the turntable 430 drives the placement table 110 to face the shape detection mechanism 200, the swing rod 240 swings to a horizontal state relative to the pin 520 of the body 500 on the placement table 110, and then the swing rod 240 slides away from the placement table 110. When the pin 520 is deformed, the detection rake 241 can contact the pin 520 when sliding and pull the body 500 out of the placement table 110. When the pin 520 is not deformed, the detection rake 241 does not contact the pin 520 when sliding.

[0047] After the swing rod 240 swings to the horizontal state, the detection rake 241 at the end of the swing rod 240 can fall to the pin 520, and the teeth of the detection rake 241 can be located on both sides of the pin 520. Then, the swing rod 240 slides in the horizontal state, so that the teeth of the detection rake 241 move linearly on both sides of the pin 520. If the pin 520 is not deformed, the detection rake 241 does not contact the pin 520, so that the detection rake 241 does not pull the diode out of the placement table 110. If the pin 520 is deformed in the horizontal plane, the detection rake 241 can contact the deformed pin 520 when moving, so that the detection rake 241 can pull the deformed diode out of the placement table 110 when moving, thereby avoiding that the probe cannot contact the pin 520 in subsequent detection.

[0048] The workbench 410 is fixedly connected with a rotating seat 220, the rotating seat 220 is rotatably connected with a rotating rod 230, and the rotating rod 230 is connected with the rotating seat 220 through a first torsional spring 231. The swing rod 240 is inserted into the middle part of the rotating rod 230, and the swing rod 240 can swing when the rotating rod 230 rotates.

[0049] The first torsional spring 231 applies a torsional force to the rotating rod 230, so that the rotating rod 230 can drive the swing rod 240 to lift up to a position not contacting the placement table 110 and the diode in a state without external force, thereby avoiding interference of the rotation of the turntable 430.

[0050] The side wall of the rotating rod 230 is fixedly connected with a connecting seat 250, the connecting seat 250 is rotationally connected with a first receiving rod 260, the first receiving rod 260 is coaxially fixedly connected with a second receiving rod 270, the first receiving rod 260 is connected with the connecting seat 250 through a second torsion spring 262, and the torsion of the second torsion spring 262 is greater than that of the first torsion spring 231; the end of the swing rod 240 away from the detection rake 241 is connected with the rotating rod 230 through an elastic rope 242, the first receiving rod 260 is wound with a first pull rope 261, and the end of the first pull rope 261 is connected to the end of the swing rod 240 close to the detection rake 241; a small motor 280 is fixedly connected to the workbench 410, the output end of the small motor 280 is fixedly connected with a third receiving rod 281, and the third receiving rod 281 is connected with the second receiving rod 270 through a second pull rope 271.

[0051] The small motor 280 can rotate in a forward direction and a reverse direction, when the pin 520 of the diode is detected, the small motor 280 rotates in the forward direction, so that the third receiving rod 281 winds the second pull rope 271, and since the torsion of the second torsion spring 262 is higher than that of the first torsion spring 231, the pulling force of the second pull rope 271 on the second receiving rod 270 can make the rotating rod 230 swing, and a cross rod is arranged on the rotating seat 220, when the swing rod 240 swings to the horizontal state, the swing rod 240 contacts the cross rod, at this time, the rotating rod 230 no longer rotates, and then the third receiving rod 281 continues to wind the second pull rope 271, at this time, the second receiving rod 270 and the first receiving rod 260 rotate against the torsion of the second torsion spring 262, so that the first receiving rod 260 receives the first pull rope 261, and the first pull rope 261 pulls the swing rod 240 to slide on the rotating rod 230, so that the elastic rope 242 is lengthened.

[0052] When the small motor 280 reverses, the third receiving rod 281 releases the second pull rope 271, and since the torsion of the second torsion spring 262 is higher than that of the first torsion spring 231, at this time, the first receiving rod 260 releases the first pull rope 261 first, at this time, the elastic rope 242 is deformed back to the original state, and pushes the swing rod 240 to reset, after the swing rod 240 resets, the detection rake 241 pushes the body 500 to further assist the body 500 to be placed on the correct position of the placement table 110, and then the first torsion spring 231 drives the rotating rod 230 to rotate to reset, so that the swing rod 240 is lifted upward, at this time, the rotating disc 430 rotates to drive the diode with the undeformed pin 520 on the placement table 110 to move to the next station.

[0053] A discharging hole 210 is arranged on the workbench 410 between the rotating seat 220 and the rotating disc 430.

[0054] The discharging hole 210 is arranged between the rotating seat 220 and the rotating disc 430, so that after the pin 520 of the deformed diode is pulled out by the detecting rake 241, the pin 520 of the deformed diode can drop out through the discharging hole 210, and a container is placed at the bottom end of the discharging hole 210 to receive the deformed diode, and then the pin 520 of the received diode can be corrected.

[0055] The feeding mechanism 300 is further arranged, and the feeding mechanism 300 comprises a housing 310 connected to the workbench 410, a transmission track 320 is connected to the housing 310, the transmission track 320 is connected to an external vibrating disc, and a second electric push rod 330 is connected to the end of the transmission track 320, and the second electric push rod 330 can push the diode on the transmission track 320 into the cylinder 120 on the placing table 110 when the second electric push rod 330 is elongated.

[0056] The external vibrating disc applies vibration to the diode, so that the diode is arranged in a required position after being vibrated and then enters the transmission track 320, and the diode moving to the lowest end of the transmission track 320 is pushed by the second electric push rod 330 to move to the placing table 110 and is inserted into the cylinder 120.

[0057] After the diode is moved to the position opposite to the first electric push rod 131 after being corrected by the polarity correction mechanism 100 and detected by the shape detection mechanism 200, the first electric push rod 131 pushes the bevel gear ring 130 to reset, then the first electric push rod 131 is shortened, and then the probe on the detecting table 420 is lowered to contact the pin 520 of the diode on the placing table 110 to detect;

[0058] The first discharging track 440 and the second discharging track 450 are further arranged on the workbench 410, and the first discharging track 440 and the second discharging track 450 are respectively used for conveying qualified diodes and unqualified diodes, and small mechanical hands (not shown in the figure) are arranged in the first discharging track 440 and the second discharging track 450 to grasp the detected diodes;

[0059] The control system compares the collected values with the set values by acquiring the values such as voltage and resistance after power is applied to the diode, if the values deviate from the set values, the corresponding small mechanical hand is controlled to operate to take out the diode when the rotating disc 430 is opposite to the first discharging track 440 or the second discharging track 450, if the diode is qualified, the corresponding small mechanical hand is controlled to operate to take out the diode when the rotating disc 430 is opposite to the first discharging track 440 or the second discharging track 450.

The bevel gear ring (130) is slidably connected to the cylinder (120). A testing platform (420) is connected to the workbench (410). An arc-shaped rack (190) is connected to the bottom of the testing platform (420). When the polarity of the body (500) is reversed, the rectangular piston cylinder (142) slides toward the body (500), and the rectangular piston rod (143) abuts against the body (500), which allows the circular piston rod (152) to extend and push the bevel ring (130) to slide on the cylinder (120). Thus, when the turntable (430) rotates, the bevel ring (130) can roll on the arc-shaped rack (190), thereby causing the body (500) to rotate 180 degrees.

2. The diode quality testing equipment according to claim 1, characterized in that: The polarity correction mechanism (100) further includes a slide (140) that slides radially on the turntable (430). The rectangular piston cylinder (142) is fixedly connected to the top of the slide (140). A protrusion (141) is fixedly connected to the side of the slide (140). A spring (160) is connected between the slide (140) and the placement platform (110). An arc-shaped baffle (170) and a wedge (180) are fixedly connected to the lower surface of the detection platform (420). When the protrusion (141) contacts the wedge (180), one end of the body (500) near the pin (520) contacts the inner surface of the arc-shaped baffle (170), so that the body (500) cannot slide relative to the cylinder (120).

3. The diode quality testing equipment according to claim 2, characterized in that: A first electric push rod (131) is fixedly connected to the worktable (410). After the turntable (430) drives the placement platform (110) to move past the arc-shaped rack (190), the cylinder (120) is directly opposite the first electric push rod (131), so that when the first electric push rod (131) extends, it can push the bevel ring (130) to reset.

4. The diode quality testing equipment according to claim 3, characterized in that: Two circular piston rods (152) are provided, and the two circular piston rods (152) are symmetrically arranged on the placement platform (110).

5. The diode quality testing equipment according to claim 4, characterized in that: Two spherical protrusions (121) are symmetrically arranged on one end face of the cylinder (120), and a spherical groove that mates with the two spherical protrusions (121) is provided on the placement platform (110).

6. The diode quality testing equipment according to claim 1, characterized in that: It also includes a shape detection mechanism (200) for detecting whether the pin (520) is bent. The shape detection mechanism (200) includes a swing arm (240) with a detection rake (241) fixedly connected to the end of the swing arm (240). When the turntable (430) drives the placement platform (110) to face the shape detection mechanism (200), the swing arm (240) swings to the pin (520) of the body (500) on the placement platform (110) to a horizontal state. Then the swing arm (240) slides away from the placement platform (110). When the pin (520) is deformed, the detection rake (241) can contact the pin (520) and pull the body (500) out of the placement platform (110) when it slides. When the pin (520) is not deformed, the detection rake (241) does not contact the pin (520) when it slides.

7. The diode quality testing equipment according to claim 6, characterized in that: A rotating base (220) is fixedly connected to the workbench (410), and a rotating rod (230) is rotatably connected to the rotating base (220).
