Description

Technical Field

[0001] This application relates to the technical field of capacitance detection, and particularly to a capacitance detection discharge device. Background Art

[0002] The circuit board of an air conditioner controller needs to use electronic components such as electrolytic capacitors with a voltage greater than 450V. Since there is often a residual voltage (ranging from 0.5V to 30V) in the electrolytic capacitors when they are received, if the residual voltage of the electrolytic capacitor is too high, there is a hidden danger of overvoltage damage to the precision electronic devices on the circuit board during the insertion process. Therefore, the electrolytic capacitor needs to be discharged before insertion so that its residual voltage reaches the safe insertion standard before insertion can be carried out. Currently, manual discharge is usually used for discharging, and there are the following problems with the manual discharge method: due to the differences in operator operations, the pins of the electrolytic capacitor do not contact the discharge plate simultaneously, resulting in the failure of detection and discharge; the discharge effect cannot be judged; the detection and discharge efficiency is low, and the labor cost is high.

[0003] Even though there are currently a small number of automatic detection and discharge devices for detection and discharge, in the current detection and discharge devices, the probes or electric pens do not accurately contact the positive and negative poles of the electrolytic capacitor, and it is still necessary to manually place the electrolytic capacitor or manually rotate the polarity of the electrolytic capacitor, resulting in a low degree of automation of the device.

[0004] Therefore, there is an urgent need to develop a capacitance detection discharge device that can automatically rotate the polarity of the capacitor to be measured when the probes or electric pens do not accurately contact the positive and negative poles of the capacitor to be measured, improving the degree of automation of the detection and discharge device.

The pushing component is arranged above the discharge port, and the pushing component pushes the capacitance to be measured out of the stacked lifting frame.

[0020] In one embodiment, the pushing component includes a pushing plate, a pushing cylinder, a pushing piston rod, and a rotating motor.

[0041] Embodiment 1

[0042] The circuit board of the air conditioner controller needs to use electronic components such as electrolytic capacitors with a voltage greater than 450V. Since there is often a residual voltage (ranging from 0.5V to 30V) when the electrolytic capacitors are received, if the residual voltage of the electrolytic capacitor is too high, there is a hidden danger of overvoltage damage to the precision electronic devices on the circuit board during the insertion process. Therefore, the electrolytic capacitor needs to be discharged before insertion, and its residual voltage needs to reach the safe insertion standard before insertion can be carried out. Currently, manual discharge is usually used for discharging, and there are the following problems with the manual discharge method: the operation of the operator is different, resulting in the pins of the electrolytic capacitor not contacting the discharge plate at the same time, resulting in the failure of detection and discharge; the discharge effect cannot be judged; the detection and discharge efficiency is low, and the labor cost is high.

[0043] Even though there are currently a small number of automatic detection and discharge devices for detection and discharge, in the current detection and discharge devices, the probes or electric pens do not accurately contact the positive and negative poles of the electrolytic capacitor, and the electrolytic capacitor still needs to be manually placed or the polarity of the electrolytic capacitor needs to be rotated manually, resulting in a low degree of automation of the device.

[0044] Therefore, there is an urgent need to develop a capacitor detection and discharge device that can automatically rotate the polarity of the capacitor to be measured when the probes or electric pens do not accurately contact the positive and negative poles of the capacitor to be measured, improving the degree of automation of the detection and discharge device.

[0045] The technical solutions of the embodiments of this application will be described in detail below with reference to the drawings.

[0046] Figure 1 is a schematic structural diagram of the capacitor detection and discharge device shown in the embodiments of this application.

[0047] See Figure 1 ,

[0048] The capacitor detection and discharge device of the embodiments of this application includes: a detection and discharge component 101, a transmission device 301, a probe member, and a polarity rotation seat 102;

[0049] The detection and discharge component 101 includes a voltage comparator;

[0050] A voltage comparator is a circuit that discriminates and compares input voltage signals and is a basic unit circuit for composing a non-sinusoidal wave generating circuit. Commonly used voltage comparators include single-threshold comparators, hysteresis comparators, window comparators, tri-state voltage comparators, etc.

[0051] The voltage comparator can be used as an interface between analog circuits and digital circuits, and can also be used as a waveform generation and conversion circuit, etc. Using a voltage comparator, a sine wave can be converted into a square wave or a rectangular wave of the same frequency.

[0052] Function of the voltage comparator: Compare the magnitudes of two voltages (using the high or low level of the output voltage to represent the magnitude relationship between the two input voltages):

[0053] When the voltage at the “+” input terminal is higher than that at the “−” input terminal, the output of the voltage comparator is at a high level.

[0054] When the voltage at the “+” input terminal is lower than that at the “−” input terminal, the output of the voltage comparator is at a low level.

[0055] The polarity rotation base 102 is arranged at the detection station A; the polarity rotation base 102 includes a receiving groove and a rotation motor, and the receiving groove is used to receive the capacitor to be measured.

[0056] When the transmission device 301 transports the capacitor to be measured to the detection station A, the probe parts are respectively connected to the voltage comparator and the capacitor to be measured.

[0057] The probe parts are not shown in the figure and include a probe board and at least two probes. The probes are fixed on the probe board. In the embodiments of the present application, the placement position of the probe board is not limited, and the placement position aims to enable the probes on the probe board to contact the positive and negative electrode inserts of the capacitor to be measured placed at the detection station A.

[0058] When the voltage comparator detects that the inserts of the capacitor to be measured are placed incorrectly, it instructs the polarity rotation base 102 to rotate the capacitor to be measured.

[0059] After the probe parts are connected to the capacitor to be measured, the voltage comparator detects the residual potential (electric potential) amount inside the capacitor to be measured to determine whether the probe parts have been correctly connected to the positive and negative electrode inserts of the capacitor to be measured. If the connection is reversed, it instructs the rotation motor to drive the polarity rotation base 102 to rotate, so that the positive and negative poles of the capacitor to be measured rotate, and then the probe parts are correctly contacted with the capacitor to be measured, and then the voltage is detected.

[0060] Advantages of the embodiment of the present application: When the transmission device transports the capacitance under test to the detection station A, the probe member is respectively connected to the voltage comparator and the capacitance under test. Since the direction of the capacitance under test transported by the transmission device is random, there is a situation where the connection between the probe member and the insertion piece of the capacitance under test is inaccurate. At this time, the polarity rotation seat can rotate the capacitance under test so that the insertion piece of the capacitance under test is exactly and accurately connected to the probe member.

[0061] In the above process, there is no need to manually rotate the polarity of the capacitance under test. Only need to transport the capacitance under test to the detection station A through the transport device. When the capacitance under test is not accurately connected to the probe member, the capacitance under test can be rotated through the polarity rotation seat to be accurately connected to the probe, and then the detection of the voltage of the capacitance under test can be implemented. This process has a high degree of automation and improves the detection efficiency of the capacitance under test.

[0062] Embodiment Two

[0063] In practical applications, after the comparator detects that the capacitance under test has a residual voltage exceeding the voltage threshold, it needs to be discharged through a discharge device. Therefore, the capacitance detection and discharge device of the embodiment of the present application further includes a discharge device.

[0064] Figure 2 It is the main structural view of the capacitance detection and discharge device shown in the embodiment of the present application including a loading mechanism;

[0065] Figure 3 It is another schematic diagram of the structure of the capacitance detection and discharge device shown in the embodiment of the present application. Refer to Figure 2 and Figure 3 .

[0066] In addition to the structure of the above Embodiment One, the capacitance detection and discharge device of the embodiment of the present application further includes a detection controller 201. The detection and discharge assembly 101 includes a discharge device and a relay.

[0067] The discharge device is a device for discharging the capacitance under test. If the residual voltage of the capacitance under test exceeds the voltage threshold, there is a hidden danger of overvoltage damage to the precision electronic devices on the circuit board during the insertion process. If the capacitance under test is not discharged as required, when the capacitance under test is powered on, it may be damaged due to the overvoltage caused by the residual charge. Therefore, it is necessary to use a discharge device for discharging. Generally, a discharge resistor discharge device is used for low-voltage capacitors, and a discharge coil discharge device is generally used for high-voltage capacitors. The specific type of the discharge device is not limited in the embodiment of the present application, and the corresponding discharge device can be adopted according to the specific situation.

[0068] A relay is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) reaches the specified requirement. It has an interaction relationship between the control system (also called the input circuit) and the controlled system (also called the output circuit).

[0069] The function of the relay in the embodiment of the present application is that the probe is connected to the relay, and the relay is connected to the voltage comparator or the discharge device according to specific circumstances.

[0070] When the voltage comparator outputs a high level or a low level, i.e., a control signal, the detection controller 201 collects the control signal and adjusts the discharge parameters to control the discharge of the discharge device. Specifically, when the voltage comparator detects that the voltage value of the capacitor under test exceeds the voltage threshold, it feeds back the detection result to the detection controller 201. The detection controller 201 sends a control signal to the relay according to the detection result that "the voltage value of the capacitor under test exceeds the voltage threshold". The relay disconnects the connection with the voltage comparator and connects the discharge device to the probe. The discharge device discharges according to the discharge parameters of the detection controller 201. After the discharge is completed, the detection controller 201 controls the relay to connect the voltage comparator terminal to the probe and disconnect the discharge device from the probe.

[0071] Furthermore, in order to ensure the discharge effect, the detection station A can be repeatedly set in the embodiment of the present application, and multiple voltage comparators and discharge devices are used, that is, detection and discharge are performed multiple times to ensure that the residual voltage of the capacitor under test meets the standard requirements. The specific number of voltage comparators and discharge devices is not limited in the embodiment of the present application and is set according to specific application situations.

[0072] The beneficial effects of the embodiment of the present application:

[0073] The voltage comparator outputs a high level or a low level, i.e., a control signal, corresponding to the detected voltage of the capacitor under test. The detection controller collects the control signal, adjusts the discharge parameters, and outputs a control signal to the discharge device to perform the discharge.

[0074] The relay is used to control the connection relationship between the probe and the voltage comparator and the discharge device by receiving the control signal of the detection controller. When the voltage comparator detects that the capacitor under test needs to perform discharge, after the detection controller outputs a discharge signal, the relay disconnects the voltage comparator connected to the probe and connects the discharge device to the probe. After the discharge is completed, the voltage comparator is connected to the probe again, and the discharge device is disconnected from the probe. This process does not require manual connection of the discharge device, and the detection controller can automatically adjust the discharge parameters, with a high degree of automation. Moreover, the voltage to be measured can be detected again after the discharge to ensure the discharge effect.

[0075] Embodiment III

[0076] The above embodiments introduce a capacitance detection and discharge device. This device can rotate the polarity rotating seat through a rotating motor to accurately connect the insertion piece of the capacitance to be measured with the probe, and then implement voltage detection and discharge. The above embodiments do not limit the placement groove of the polarity rotating seat. Embodiments of the present application will further introduce the capacitance detection and discharge device.

[0077] Referring to Figure 1 , the polarity rotating seat 102 of the capacitance detection and discharge device in the embodiments of the present application further includes a limiting piece 103. The limiting piece 103 is arranged at the top of the accommodating groove. When the capacitance to be measured is placed in the accommodating groove, the limiting piece 103 is pressed down by the detection controller 201 to press the capacitance to be measured. The setting of the limiting piece 103 can prevent the capacitance to be measured in the accommodating groove from bouncing upwards or even popping out of the accommodating groove when the polarity rotating seat 102 rotates. In addition to this function, the limiting piece 103 can also limit the capacitance to be measured so that the capacitance to be measured can be placed in the accommodating groove, facilitating the contact between the insertion piece of the capacitance to be measured and the probe.

[0078] The polarity rotating seat 102 can also be provided with a first sensor. After the first sensor senses that a capacitance to be measured is placed in the accommodating groove, it sends a signal to the detection controller 201, and the detection controller 201 then controls the limiting piece 103 to press the capacitance to be measured.

[0079] In the embodiments of the present application, an exemplary transmission device 301 is used to transport the capacitance to be measured to the accommodating groove. The transmission device 301 communicates with both sides of the side wall of the accommodating groove, that is, the transmission device 301 can transport the capacitance to be measured to the accommodating groove, and can transport the capacitance to be measured away from the accommodating groove after the capacitance detection and discharge are completed.

[0080] At the same time, the transmission device 301 adopted in the embodiments of the present application is also for facilitating the insertion process after the capacitance detection and discharge of the capacitance to be measured. The insertion of the capacitance to be measured is that the insertion piece of the capacitance to be measured is inserted into the insertion hole of the circuit board, which is in the state where the insertion piece is downward. Therefore, the transmission device 301 of the embodiments of the present application includes two transmission belts and relatively arranged transmission protection plates. The transmission protection plates are arranged on both sides of the transmission belts along the transmission direction. The function of the transmission protection plates is to prevent the capacitance to be measured from falling over during transmission. The two transmission belts are arranged side by side on the transmission plane, and the arrangement direction is perpendicular to the transmission direction. The distance between the two transmission belts is smaller than the diameter of the capacitance to be measured. The transmission device 301 formed by the two transmission belts enables the insertion piece of the capacitance to be measured to fall into the gap between the two transmission belts and run to the accommodating groove along with the transmission belts.

[0081] The transmission device 301 of the embodiments of the present application includes a first transmission section and a second transmission section. The first transmission section is the incoming material transmission section of the detection station A, that is, the capacitance to be measured on the first transmission section has not been subjected to detection and discharge yet, and the second transmission section is the transmission section where the capacitance to be measured leaves the detection station A.

[0082] The distance between the two conveyor belts in the first transmission section is set to be gradually narrowed from wide to narrow, that is, the spacing between the two conveyor belts gradually narrows. The gradually narrowing structure can limit the insertion direction of the capacitor under test, so that the insertion distribution direction of the capacitor under test during transmission is consistent with the transmission direction, which is convenient for accurate contact with the probe member.

[0083] The probe member of the embodiment of the present application is correspondingly arranged below the accommodation groove. When the capacitor under test runs to the accommodation groove, the insertion piece can contact the probe member below the accommodation groove. Since the insertion arrangement direction of the capacitor under test is consistent with the transmission direction, there are two situations for the insertion pieces of the capacitor under test at this time. One is that the positive and negative insertion pieces accurately contact the probe member, and then the voltage can be directly detected and discharged. The other situation is that the positive and negative insertion pieces are in reverse contact with the probe member. Then, the capacitor under test is rotated 180 degrees by the polarity rotation seat 102 so that the insertion pieces of the capacitor under test accurately contact the probe member, and the next step of voltage detection and discharge is carried out.

[0084] The beneficial effects of the embodiment of the present application: The setting of the limiting piece enables the polarity rotation seat to prevent the capacitor under test in the accommodation groove from bouncing upward or even popping out of the accommodation groove when rotating. In addition to this function, the limiting piece can also limit the capacitor under test so that the capacitor under test can be accommodated in the accommodation groove, which is beneficial to the contact between the insertion pieces of the capacitor under test and the probe member. The setting that the spacing between the two conveyor belts of the transmission device gradually narrows can make the insertion arrangement direction of the capacitor under test during transmission consistent with the transmission direction, which is convenient for accurate contact with the probe member in the accommodation groove.

[0085] Embodiment Four

[0086] The above embodiment introduced that the capacitance detection and discharge device includes a transmission device. The capacitance detection and discharge device of the embodiment of the present application further includes a hollow spiral tube. Because when the capacitor under test is stored, it is usually stored in a way that the insertion piece is upward, while when the capacitor under test is inserted into the circuit board, it is inserted in a way that the insertion piece is inserted into the circuit board. Therefore, in order to make the insertion piece of the capacitor under test downward in this insertion step without the operation of turning the insertion piece from upward to downward and then inserting it, the embodiment of the present application further includes a hollow spiral tube.

[0087] Figure 4 It is the left view of the structure of the capacitance detection and discharge device including the feeding mechanism shown in the embodiment of the present application;

[0088] Figure 5 It is the top view of the structure of the capacitance detection and discharge device including the feeding mechanism shown in the embodiment of the present application. See Figure 4 and Figure 5 .

[0089] The capacitance detection and discharge device according to the embodiment of the present application further includes a hollow spiral tube 401. A spiral track is arranged inside the spiral tube. The hollow spiral tube 401 is arranged at one end of the first transmission section and is communicated with the first transmission section. When the capacitance under test with the insert upward passes through the hollow spiral tube 401, the capacitance under test slides down by its own gravity, slides down inside the hollow spiral tube 401, and slides down in the spiral track inside the hollow spiral tube 401. The spiral track causes the capacitance under test to change direction, and the capacitance under test naturally spirally flips 180 degrees. After the capacitance under test flips 180 degrees, it slides down to the first transmission section, and then the capacitance under test runs through the first transmission section to the receiving slot.

[0090] Advantageous effects of the embodiment of the present application: The setting of the hollow spiral tube enables the capacitance under test to naturally spirally flip 180 degrees. After the capacitance under test flips 180 degrees, it slides down to the first transmission section, and the insert of the capacitance under test after flipping is downward, which is convenient for the capacitance under test to be inserted into the circuit board.

[0091] Embodiment Five

[0092] The feeding structure of the capacitance detection and discharge device is not mentioned in the previous embodiments. The capacitance detection and discharge device according to the embodiment of the present application further includes a feeding mechanism.

[0093] Figure 6 It is a schematic structural diagram of the feeding mechanism of the capacitance detection and discharge device shown in the embodiment of the present application;

[0094] Figure 7 It is another schematic structural diagram of the feeding mechanism of the capacitance detection and discharge device shown in the embodiment of the present application. Refer to Figure 6 and Figure 7 .

[0095] In addition to the structures mentioned in the above embodiments, the capacitance detection and discharge device according to the embodiment of the present application further includes a feeding mechanism 501. The feeding mechanism 501 includes a stacked lifting frame 510, a material plate 520, and a pushing component 530. The material plate 520 is used to place the capacitance under test, and the stacked lifting frame 510 is used to place the material plate 520. The size structure of the material plate 520 is set according to the material plate 520 that can be accommodated by the stacked lifting frame 510, and the embodiment of the present application does not make any restrictions. The stacked lifting frame 510 includes a switch control key, a lifting frame body 511, a servo motor 512, a lead screw 513, and a guide rod 514. The material plate 520 is placed on the lifting frame body 511. The lead screw 513 and the guide rod 514 are arranged on the lifting frame body 511. The servo motor 512 operates to drive the lead screw 513 to rotate, and the material plate 520 rises along the guide rod 514 to the discharge port position of the stacked lifting frame 510. The discharge port position is the position where the capacitance under test leaves the stacked lifting frame 510.

[0096] The discharge port of the stacked lifting frame is communicated with the hollow spiral tube 401, and the pushing component 530 is arranged above the discharge port. The pushing component 530 pushes the capacitor to be measured into the hollow spiral tube 401.

[0097] The pushing component 530 includes a pushing plate 531, a pushing cylinder 532, a pushing piston rod 533 and a rotating motor 534. The two ends of the pushing piston rod 533 are respectively connected to the pushing plate 531 and the pushing cylinder 532. The pushing cylinder 532 controls the pushing plate 531 to push the material, and the rotating motor 534 controls the rotation of the pushing plate 531.

[0098] When the pushing plate 531 of the embodiment of the present application is not working, it is in a parallel state with the partition plate of the stacked lifting frame to prevent interference with the capacitor to be measured in the material plate 520. When the pushing plate 531 needs to push out the capacitor to be measured, the rotating motor 534 controls the pushing plate 531 to rotate. The rotation angle of the pushing plate 531 is not limited in the embodiment of the present application. After rotation, the pushing plate 531 contacts the capacitor to be measured, and the pushing cylinder 532 drives the pushing plate 531 to push out the capacitor to be measured. After the capacitor to be measured is pushed out, the material plate 520 returns to be parallel to the material plate 520 of the stacked lifting frame again.

[0099] In addition to the pushing component 530, the embodiment of the present application also sets a pushing plate component 540 for pushing the material plate 520. The pushing plate component 540 is arranged above the discharge port. When all the capacitors to be measured on the material plate 520 are pushed out, the pushing plate component 540 can push the empty material plate 520 out of the stacked lifting frame 510, and the material plate 520 falls into the turnover box 901 arranged on one side of the stacked lifting frame 510.

[0100] The beneficial effects of the embodiment of the present application: Through the setting of the stacked lifting frame, the material plate and the pushing component, the stacked lifting frame can transport the material plate with the capacitor to be measured to the position of the discharge port, and the pushing component pushes the capacitor to be measured into the hollow spiral tube, completing the automatic feeding action of the capacitor to be measured, improving the automation degree of the capacitor detection and discharge device, and improving the production efficiency of the production line.

[0101] Embodiment Six

[0102] In addition to the structure introduced in the above embodiments, the feeding mechanism of the capacitor detection and discharge device in the embodiment of the present application further includes a guiding component.

[0104] Figure 7 It is another schematic structural diagram of the feeding mechanism of the capacitor detection and discharge device shown in the embodiment of the present application. See Figure 6 and Figure 7 .

[0105] The guiding assembly 601 includes a buffer bottom plate 610, two oppositely arranged guiding plates 620 and a guiding cylinder 630. The guiding plates 620 are arranged on the buffer bottom plate 610. Both ends of the buffer bottom plate 610 are respectively connected to the discharge port and the opening of the hollow spiral tube 401. The guiding cylinder 630 controls the distance between the guiding ends of the guiding plates 620. The guiding ends are the ends of the guiding plates 620 close to the opening end of the hollow spiral tube 401. The buffer bottom plate 610 plays a buffering role in temporarily accommodating the capacitors to be tested.

[0106] The guiding assembly 601 may also be provided with a second sensor. The second sensor detects the quantity and position of the capacitors to be tested on the buffer bottom plate 610, and sends the signals of the quantity and position to the detection controller 201. The detection controller 201 activates the guiding cylinder 630. The guiding cylinder 630 controls the distance of the guiding ends, and controls the speed and quantity of the capacitors to be tested entering the hollow spiral tube 401 through the opening size of the guiding ends. Thus, the feeding of the capacitors to be tested can be carried out orderly, avoiding too many capacitors to be tested entering the hollow spiral tube 401 at the same time or no capacitors to be tested entering the hollow spiral tube 401 for a long time, which affects the normal detection and discharge efficiency.

[0107] The beneficial effects of the embodiments of the present application: The setting of the guiding assembly can block, release the capacitors to be tested and prevent the capacitors to be tested from jamming and not falling, and at the same time, cooperate with the second sensor to carry out the feeding of the capacitors to be tested orderly.

[0108] Embodiment Seven

[0109] The capacitors to be tested after detection and discharge are divided into two situations. One is qualified and can be inserted onto the circuit board, and the other is unqualified and needs to be discarded. The embodiments of the present application have made inventive settings for the above two situations. The embodiments of the present application also include a plug-in mechanism and a waste material mechanism.

[0110] Figure 8 is a schematic structural diagram of the plug-in mechanism of the capacitor detection and discharge device shown in the embodiments of the present application;

[0111] Figure 9 is a schematic structural diagram of the waste material mechanism of the capacitor detection and discharge device shown in the embodiments of the present application. Refer to Figure 8 and Figure 9 .

[0112] The plug-in mechanism 701 and the waste material removal mechanism 702 are arranged on the second transmission section of the transmission device 301. The measured capacitor after detecting discharge travels along the transmission direction and first passes through the waste material removal mechanism 702 before reaching the plug-in mechanism 701. The plug-in mechanism 701 includes a third sensor 711, a plug-in electric cylinder 712, and a vacuum suction cup 714. The plug-in electric cylinder 712 includes an electric cylinder shaft 713, and the vacuum suction cup 714 is arranged on the electric cylinder shaft 713. The plug-in electric cylinder 712 controls the vacuum suction cup 714 to adsorb the measured capacitor and place it at the plug-in position.

[0113] The plug-in mechanism 701 further includes a laser rangefinder 715, and the laser rangefinder 715 detects whether the measured capacitor is inserted in place.

[0114] Exemplarily, the measured capacitor after detecting discharge leaves the detection station A through the second transmission section. The detection controller 201 of the detection and discharge device in the embodiment of the present application automatically judges whether the discharge effect of the measured capacitor meets the plug-in standard by storing the detection and discharge results. When the detection and discharge results do not meet the plug-in standard, when the measured capacitor after detecting discharge is transported to the waste material removal mechanism 702, the waste material removal mechanism 702 includes a waste material cylinder 721 and a concave push rod 722. The waste material cylinder 721 drives the concave push rod 722 to extend and push the unqualified measured capacitor after detecting discharge to the unqualified buffer line on one side of the second transmission section for further manual confirmation and verification.

[0115] When the detection and discharge results meet the plug-in standard, the second transmission section directly transports the measured capacitor to the position where the measured capacitor is to be inserted. The third sensor 711 detects and judges whether the measured capacitor after detecting discharge is transported to the position where it is to be inserted. If the third sensor 711 detects that the measured capacitor after detecting discharge has reached the position where it is to be inserted, the first stopper 716 is used to block the measured capacitor. The capacitor detection and discharge device in the embodiment of the present application further sets a circuit board transmission line 801. The circuit board transmission line 801 is provided with a second stopper 810. When there is a circuit board with a measured capacitor to be inserted, the second stopper 810 is used to block and position the circuit board. After the blocking and positioning are completed, the detection controller 201 controls the plug-in electric cylinder 712 to operate, and the vacuum suction cup 714 is lowered to the measured capacitor through the electric cylinder shaft 713 and the measured capacitor is sucked by the vacuum suction cup 714. After the measured capacitor is sucked by the vacuum suction cup 714, the plug-in electric cylinder 712 drives the electric cylinder shaft 713 to extend and transports the measured capacitor sucked on the vacuum suction cup 714 above the circuit board with the capacitor to be inserted. The plug-in electric cylinder 712 moves the measured capacitor sucked on the vacuum suction cup 714 to the position where the capacitor is to be inserted on the circuit board. The vacuum suction cup 714 exhausts air to vertically insert the measured capacitor into the corresponding hole on the circuit board. The laser rangefinder 715 detects whether the measured capacitor is inserted in place (by detecting the height of the capacitor). When it detects unqualified, a control signal is output to jointly control the circuit board transmission line 801 to stop and alarm to prompt the staff to handle. After the measured capacitor is inserted, the plug-in electric cylinder 712 reciprocates in a cycle.

[0116] Advantages of the embodiments of the present application: By providing a plug-in mechanism and a waste material mechanism, the plug-in mechanism can automatically insert the measured capacitors that pass the detection of discharge into the circuit board, while the waste material mechanism can push the unqualified measured capacitors away from the transmission device, avoiding inserting the unqualified measured capacitors into the circuit board and causing the circuit board to be unqualified. The embodiments of the present application can not only automatically detect and discharge the measured capacitors, but also perform qualified insertion of the measured capacitors, thereby improving the detection, discharge and assembly efficiency of the measured capacitors as a whole.
