Description

Technical Field

[0001] The utility model relates to the technical field of electrical component discharge, and particularly to a discharge device. Background Art

[0002] The electrical box is the core component of an air conditioner. During the production of the electrical box, relevant electrical components need to be inserted onto the main board. To avoid the static charge stored in the electrical components from breaking down and damaging the main board during the insertion process of the electrical components, the electrical components are often discharged before insertion to release the static charge in the electrical components.

[0003] In the related art, the static charge in the electrical component is released by contacting the pins of the electrical component with the probes on the discharge board. To ensure the static discharge effect, the electrical component needs to be attached to the probes. However, it is difficult to control the static discharge. When the electrical component is pressed down too tightly, the pressing force will cause the probes to deform and be damaged. When the electrical component is not pressed down, it is easy to cause poor contact between some probes and the electrical component, thus affecting the static discharge effect. Summary of the Utility Model

[0004] The utility model provides a discharge device for improving the static discharge effect.

[0005] The utility model provides a discharge device, including: a discharger, which includes a housing and a discharge assembly, and the discharge assembly is installed in the housing; a positioning member, which is installed in the housing and passes through the discharge assembly, the top height of the positioning member is higher than the top height of the discharge assembly, and the positioning member can move downward under pressure; and a detector, which is connected to the positioning member to detect the downward displacement of the positioning member.

[0006] In one embodiment, the discharge device further includes an alarm, which can emit a sound alarm signal and / or a photoelectric alarm signal, and the alarm is electrically connected to the detector.

[0007] In one embodiment, at least two positioning members are installed in the housing, the positioning members are spaced from each other, and each positioning member is connected to a corresponding detector, and each detector is electrically connected to the alarm.

[0013] In one embodiment, the transfer assembly includes a chain transfer mechanism and a lifting mechanism. The inlet is located at one end of the chain transfer mechanism, and the lifting mechanism is arranged at the other end of the chain transfer mechanism.

[0014] In one embodiment, a reflux assembly is further included, and the reflux assembly is arranged on one side of the discharger.

[0015] Compared with the prior art, the advantages of the present utility model are as follows: when it is necessary to release static electricity from an electrical component, the electrical component can be placed on the positioning member.

[0036] The present utility model will be further described below in conjunction with the accompanying drawings.

[0037] See Figure 1 and Figure 2 As shown, a discharging device provided by the present utility model includes a discharger 100, a positioning member 200, and a detector 300.

[0038] The discharger 100 includes a housing 110 and a discharge assembly 120. The positioning member 200 and the discharge assembly 120 are disposed within the housing 110. The positioning member 200 passes through the discharge assembly 120, and the top height of the positioning member 200 is greater than the top height of the discharge assembly 120. When the electrical component 700 to be discharged is placed on the top of the positioning member 200, if the positioning member 200 is not pressed down, the bottom surface height of the electrical component 700 will be higher than the top height of the discharge assembly 120 under the support of the positioning member 200, avoiding contact between the electrical component 700 and the discharge assembly 120 and damaging the discharge assembly 120. When pressing down on the electrical component 700, the positioning member 200 moves downward until the top surface height of the positioning member 200 is equal to the top height of the discharge assembly 120, enabling the positioning member 200 and the discharge assembly 120 to jointly support the electrical component 700, avoiding the compression force being concentrated on the probe of the discharge assembly 120 and reducing the bending deformation of the probe.

[0039] See Figures 2 to 4 As shown, in some implementation manners, a detector 300 connected to the positioning member 200 can detect the downward displacement of the positioning member 200. Based on the downward displacement of the positioning member 200, it can be determined whether the top of the positioning member 200 has moved downward to be equal to the top height of the discharge assembly 120. If the downward displacement of the positioning member 200 is less than the height difference between the top of the positioning member 200 and the top of the discharge assembly 120 in the initial state, it indicates that the bottom of the current electrical component 700 does not contact the discharge assembly 120, and the discharge assembly 120 cannot be electrically connected to the electrical component 700 above the positioning member 200, and thus the static charge stored in the electrical component 700 cannot be released.

[0040] In some implementation manners, the detector 300 is electrically connected to an alarm 400, which can remind the staff whether the electrical component 700 has moved into place in the current state through the alarm 400. When the downward displacement of the positioning member 200 is insufficient, the alarm 400 electrically connected to the detector 300 gives a reminder, informing the operator that the current compression force is insufficient and further compression is required to achieve the static charge release of the electrical component 700.

[0041] In some implementation manners, the alarm 400 includes a voice alarm module. When the detector 300 measures that the downward displacement of the positioning member 200 is less than the calibrated displacement (the height difference between the top of the positioning member 200 and the top of the discharge assembly 120 in the initial state), the voice alarm module emits a sound signal to remind the operator that the static charge release of the current electrical component 700 fails and the static charge release operation needs to be performed again.

[0042] In some other implementations, the alarm 400 further includes a photoelectric alarm module. When the detector 300 measures that the downward displacement of the positioning member 200 is less than the standard displacement, the photoelectric alarm module emits photoelectric information, such as lighting a danger indicator light, to remind the operator that the electrostatic discharge of the current electrical component 700 fails and the electrostatic discharge operation needs to be performed again.

[0043] It can be understood that, in some implementations, the detector 300 can select a detection device with a measured displacement indication number. By displaying the downward displacement of the positioning member 200 in real time, it helps the staff to judge whether the electrical component 700 is pressed in place, so as to better release the static electricity stored in the electrical component 700 through the discharge assembly 120.

[0044] That is to say, in this application, not only can the positioning member 200 with a top height higher than the discharge assembly 120 be used to support the electrical component 700, reduce the pressure borne by the discharge assembly 120 during the electrostatic discharge process, and avoid damage to the discharge assembly 120. Moreover, by measuring whether the displacement of the positioning member 200 reaches the standard displacement, it is judged whether the electrostatic discharge work is completed. When the pressing force is insufficient, the alarm 400 can be used to give an alarm to remind the operator to adjust in time, and avoid the un-discharged electrical component 700 flowing into the insertion process and discharging the static electricity into the main board to break through the main board.

[0045] See Figure 8 and Figure 9 As shown, the electrical component 700 can be a capacitor. The electrical component 700 includes a component body 710, and a first pin 720 and a second pin 730 are arranged on the top surface of the component body 710. Among them, in some implementations, the first pin 720 is the cathode of the electrical component 700, and the second pin 730 is the anode of the electrical component 700. When discharging static electricity for the electrical component 700, by contacting the first pin 720 and the second pin 730 with the discharge assembly 120, the charge stored in the electrical component 700 is guided into the discharge assembly 120 and is guided to the ground through the discharge assembly 120.

[0046] It can be understood that the electrical component 700 is not limited to the capacitor mentioned above, and the discharge device provided in this application can also release static electricity charges for other products.

[0047] See Figure 1 and Figure 4As shown, the housing 110 is formed with a receiving cavity 111 having an opening. The discharge assembly 120 is installed in the receiving cavity 111, and the top height of the discharge assembly 120 is lower than the height of the opening. The aperture of the opening of the receiving cavity 111 can be set to be the same as the outer diameter of the electrical component 700, so that when the electrical component 700 is inserted into the opening of the receiving cavity 111 to release static electricity, the electrical component 700 can be prevented from tilting through the side wall of the receiving cavity 111.

[0048] See Figure 4 and Figure 5 As shown, in some implementation manners, at least two positioning members 200 are installed in the housing 110. The positioning members 200 are spaced from each other, and each positioning member 200 is connected to a corresponding detector 300. Each detector 300 is electrically connected to the alarm 400.

[0049] By increasing the number of the positioning members 200, it is possible to detect whether multiple regions of the electrical component 700 move downward to fit with the discharge assembly 120, so as to measure the bottom surface angle of the electrical component 700. See Figure 1 and Figure 5 As shown, two positioning members 200 are provided inside the housing 110. When the downward displacement of the top end of one of the positioning members 200 reaches the standard displacement, while the downward displacement of the top end of the other positioning member 200 is less than the standard displacement, it indicates that the displacements of the regions of the electrical component 700 in contact with the two positioning members 200 are different, that is, some regions of the electrical component 700 above the positioning member 200 do not move downward to contact the discharge assembly 120, and the static electricity release effect is lower than the expected static electricity release effect.

[0050] When the downward displacements detected by each detector 300 for the corresponding positioning member 200 all reach the standard displacement, it indicates that all regions of the bottom of the electrical component 700 are in contact with the discharge assembly 120, and the electrical component 700 can achieve a better static electricity release effect through the discharge assembly 120. At this time, the alarm 400 electrically connected to each detector 300 does not emit an alarm signal.

[0051] When there is one detector 300 detecting that the downward displacement of the corresponding positioning member 200 is less than the standard displacement, or the corresponding positioning member 200 does not move downward, the alarm 400 emits an alarm signal to remind the operator that the current angle of the electrical component 700 is inappropriate and does not meet the requirements of static electricity release, and the position of the electrical component 700 needs to be adjusted before performing the static electricity release work.

[0052] See Figure 5 and Figure 6 As shown, it can be understood that the number of the positioning members 200 provided in the housing 110 can be more than two, so as to achieve more accurate angle positioning of the electrical component 700.

[0053] See Figure 1 and Figure 4 As shown, the positioning member 200 includes a spherical head and a connecting rod, and the spherical head is provided at the top end of the connecting rod. In some implementation manners, the top end height of the spherical head is greater than the top end height of the discharge probe 122, and the spherical head adopts a structure with a certain softness such as rubber or cork to prevent the spherical head from damaging the electrical component 700 when the spherical head contacts the electrical component 700.

[0054] See Figure 3 and Figure 5 As shown, the bottom of the connecting rod is also provided with a spherical surface structure, and a roller is connected at the detector 300 and is connected to the bottom of the connecting rod through the roller structure to reduce the friction between the positioning member and the detector 300.

[0055] See Figure 3 and Figure 5 As shown, the detector 300 includes a microswitch, the microswitch is connected to the positioning member 200, and the microswitch is electrically connected to the alarm 400. Among them, in some implementation manners, the trigger end of the microswitch is connected to the bottom of the positioning member 200. When the positioning member 200 moves downward, the trigger end of the microswitch will move downward synchronously with the downward movement of the positioning member 200. When the downward displacement of the positioning member 200 reaches the calibrated displacement, the microswitch sends a switch signal to the alarm 400, and the alarm 400 determines whether to send an alarm signal based on the switch signals of each microswitch. Specifically, when the number of switch signals received by the alarm 400 from the microswitch is less than the number of microswitches, the alarm 400 sends an alarm signal to remind that the downward displacement of some positioning members 200 is less than the calibrated displacement, and the electrostatic discharge effect of the electrical component 700 does not meet the electrostatic discharge standard. When the number of switch signals received by the alarm 400 from the microswitch is equal to the number of microswitches, the controller does not send an alarm signal.

[0056] Among them, the microswitch has an automatic reset function. When there is no pressure on the top of the positioning member 200, the reset of the microswitch will push up the positioning member 200 to synchronously realize the reset of the positioning member 200.

[0057] It can be understood that in other implementation manners, the detector 300 can also be a displacement sensor, which directly measures the moving displacement of the positioning member 200 and transmits the moving displacement to the alarm 400.

[0058] See Figure 3 and Figure 6As shown, in some implementations, the discharger 100 further includes an elastic member 130. The discharge assembly 120 can move vertically inside the housing 110. The top end of the elastic member 130 is connected to the discharge assembly 120, and the bottom end of the elastic member 130 is connected to the housing 110. When the downward pressure received by the electrical component 700 placed on the positioning member 200 is relatively large, the discharge assembly 120 can move downward to avoid deformation and damage of the probe in the discharge assembly 120. After the electrostatic discharge is completed, the elastic member 130 can drive the discharge assembly 120 to move upward to reset the discharge assembly 120.

[0059] Participate Figure 3 And Figure 6 As shown, in some implementations, two elastic members 130 are provided inside the housing 110, and the elastic members 130 are springs. By providing two elastic members 130, the risk of the discharge assembly 120 deflecting inside the housing 110 can be reduced.

[0060] It can be understood that, in some implementations, a first guiding structure extending vertically can be provided on the housing 110, and a corresponding second guiding structure can be provided on the discharge assembly 120. Through the cooperation of the first guiding structure and the second guiding structure, the moving direction of the discharge assembly 120 is restricted to vertical movement. Among them, the first guiding structure can be set as a vertically extending groove structure, and correspondingly, the second guiding structure can be set as a convex block structure. By inserting the second guiding structure into the first guiding structure, the moving direction of the discharge assembly 120 is restricted. Of course, the first guiding structure can also be set as a vertically extending convex block structure, and correspondingly, the second guiding structure can be set as a groove structure. By inserting the first guiding structure into the second guiding structure, the moving direction of the discharge assembly 120 is restricted.

[0061] See Figure 3 And Figure 6 As shown, a vertically extending buffer support column is provided inside the housing 110, and the elastic member 130 is sleeved outside the buffer support column. By providing the buffer support column, it can be avoided that the spring elastic member 130 bends when compressed, ensuring that the elastic deformation direction of the elastic member 130 is always along the vertical direction.

[0062] Participate Figure 4 As shown, the discharge assembly 120 includes a discharge plate 121 and a discharge probe 122. The discharge probe 122 is located above the discharge plate 121 and the discharge probe 122 is electrically connected to the discharge plate 121. The discharge probe 122 located above the discharge plate 121 is electrically connected to the electrical component 700 to direct the static charge of the electrical component 700 into the discharge plate 121 to release the charge. Since the top of the discharge probe 122 is relatively sharp, compared with a plate-like structure, it can better draw out the charge in the electrical component 700 to complete the work of electrostatic discharge.

[0063] In some implementations, the discharge plate 121 is electrically connected to a ground wire. After the discharge probe 122 introduces the charges in the electrical component 700 into the discharge plate 121, the ground wire electrically connected to the discharge plate 121 can direct the charges in the discharge plate 121 to the ground, preventing the charges from accumulating in the discharge plate 121.

[0064] See Figure 2 and Figure 7 as shown. In some implementations, the discharge device further includes a transfer assembly 500. The transfer assembly 500 is configured to transport the workpiece from the loading port to the temporary storage station, and the discharger 100 is disposed on one side of the temporary storage station.

[0065] Integrating the transfer assembly 500 in the discharge device can avoid fetching the workpiece from a distance and then performing the discharge operation during the discharge process, reducing the labor intensity of the discharge work.

[0066] The loading port of the transfer assembly 500 can be docked with the production line or assembly line of the electrical component 700, so that the electrically produced component 700 or the assembled electrical component 700 can be directly transported to the temporary storage station through the transfer assembly 500. The discharge operator can then take out the electrical component 700 from the temporary storage station and place the electrical component 700 in the discharger 100 to release the static charges in the electrical component 700.

[0067] See Figure 2 and Figure 7 as shown. A feeding detection sensor 540 is provided at the loading port. The feeding detection sensor 540 is electrically connected to the transfer assembly 500. By means of the feeding detection sensor 540 provided at the loading port, it can be detected whether there is a workpiece to be transported at the loading port of the transfer assembly 500. After the feeding detection sensor 540 detects that there is a workpiece at the loading port, the feeding detection sensor 540 sends a feeding signal to the transfer assembly 500, and the transfer assembly 500 then starts according to the feeding signal to transport the workpiece at the loading port to the temporary storage station for the operator to pick up. After transporting the electrical component 700 to the temporary storage station, if the feeding detection sensor 540 does not detect the electrical component 700 at the loading port, the transfer assembly 500 can be stopped to reduce energy consumption.

[0068] In some implementations, the feeding detection sensor 540 includes a photoelectric sensor disposed facing the loading port, and measures whether there is an electrical component 700 at the loading port through the photoelectric detection principle. In other implementations, the feeding detection sensor 540 may further include an electromagnetic sensor or an infrared sensor, as long as it can detect whether there is an electrical component 700 at the loading port, and the specific structure of the feeding detection sensor 540 is not limited.

[0069] See Figure 2 andFigure 7 As shown, in some implementations, the conveying component 500 includes a chain conveying mechanism 520 and a lifting mechanism 530. The feeding port is located at one end of the chain conveying mechanism 520, and the lifting mechanism 530 is arranged at the other end of the chain conveying mechanism 520. The chain conveying mechanism 520 can achieve long-distance transportation of materials, and the lifting mechanism 530 can lift the electrical components 700 at a low position, facilitating the operator to grasp the electrical components 700, avoiding the operator bending down to grasp the electrical components 700, and reducing the operation difficulty of the staff.

[0070] Among them, in some implementations, the lifting mechanism 530 includes a first cylinder 531 and a support plate 532 arranged at the end of the first cylinder 531. By the telescopic movement of the first cylinder 531 in the vertical direction, the vertical height of the support plate 532 can be adjusted, thereby lifting the electrical components 700 on the support plate 532.

[0071] It can be understood that the lifting mechanism 530 can also select a vertically extending rack and pinion mechanism as the driving component. Through the rotation of the gear mechanism, the up and down movement of the vertically arranged rack is driven, so as to move the support plate 532 fixedly connected to the rack up and down, and complete the lifting of the electrical components 700. Of course, a manipulator can also be directly used to grasp and lift the electrical components 700 placed on the chain conveying mechanism 520.

[0072] See Figure 2 and Figure 7 As shown, the chain conveying mechanism 520 includes two groups of chains arranged at intervals, and the interval distance between the two groups of chains is less than the width of the storage box, so that the chain conveying mechanism 520 can realize the transportation of the storage box containing multiple electrical components 700. The support plate 532 of the lifting mechanism 530 is arranged at the end of the chain conveying mechanism 520 far from the feeding port, and the support plate 532 is located between the two chain assemblies 521. When the lifting mechanism 530 is not lifting, the top surface height of the support plate 532 is lower than or equal to the top surface height of the two chain assemblies 521, so that the chain conveying mechanism 520 can directly transport the storage box above the support plate 532, and then through the vertical elongation of the first cylinder 531, drive the support plate 532 and the storage box above the support plate 532 to move upward, realizing the lifting of the electrical components 700.

[0073] See 2 and Figure 7 As shown, in some implementations, in order to better support the storage box, flow strips 522 are also arranged at both ends of the chain assembly 521, and the storage box can be supported by the flow strips 522.

[0074] To achieve the automation of the lifting action, when the incoming material detection sensor 540 provided at the incoming material port detects the presence of a storage box at the incoming material port, the first cylinder 531 is first vertically contracted to drive the support plate 532 to move downward, so that the top surface height of the support plate 532 is lower than the top surface height of the two chain assemblies 521. Then, the chain transmission mechanism 520 is started, and the storage box is transported above the support plate 532 through the chain transmission mechanism 520.

[0075] A lifting detection sensor 550 is also provided at the support plate 532, and the lifting detection sensor 550 is electrically connected to the first cylinder 531. When the lifting detection sensor 550 detects the presence of a storage box on the support plate 532, the lifting detection sensor 550 sends an electrical signal to the first cylinder 531, and the first cylinder 531 is used to extend and jack up the storage box. The storage box is lifted near the discharger 100 to facilitate the staff to release the static electricity of the electrical components 700 in the storage box.

[0076] See Figure 2 and Figure 7 As shown in

[0077] See Figure 2 and Figure 7 As shown, a transfer frame body 510 is provided at one end of the chain transmission mechanism 520 away from the incoming material port. The transfer frame body 510 is provided with a buffer plate facing the chain transmission mechanism 520. When the storage box is transported to the frame body by the chain transmission mechanism 520, the storage box contacts the buffer plate, and the vibration of the storage box is absorbed through the buffering function of the buffer plate to prevent the storage box from being deformed due to excessive impact. Among them, the buffer plate can be supported by sponge, and the impact is absorbed through the deformation of the buffer plate. A spring structure can also be provided between the buffer plate and the frame body to further absorb the collision impact through the deformation of the spring.

[0078] See Figure 2 and Figure 7 As shown, a blocking cylinder 560 is provided at the connection between the chain transmission mechanism 520 and the lifting mechanism 530. When the lifting detection sensor 550 detects the presence of a storage box above the support plate 532, the blocking cylinder 560 extends upward to prevent subsequent storage boxes from being transported to the first cylinder 531.

[0079] See Figure 2 and Figure 7As shown, a temporary storage position detection sensor 580 is further provided on the transfer frame 510. The temporary storage position detection sensor 580 is arranged facing the temporary storage station of the transfer device to detect whether there is a storage box at the temporary storage station. When the temporary storage position detection sensor 580 detects that there is a storage box at the temporary storage station, the first cylinder 531, the second flagpole, and the blocking cylinder 560 are controlled to lock, so that the support plate 532 and the support member 534 are maintained at the lifting height to prevent the storage box from moving downwards.

[0080] See Figure 2 and Figure 7 As shown, in some implementation manners, the discharge device further includes a return flow assembly 600. The return flow assembly 600 is arranged on one side of the discharger 100. After the discharger 100 releases static electricity to the electrical component 700, the electrical component 700 after releasing static electricity can be directly placed on the return flow assembly 600, and the electrical component 700 after releasing static electricity flows to the next station (such as the insertion station) through the return flow assembly 600, saving the work of the staff to carry the electrical component 700.

[0081] See Figure 2 and Figure 7 As shown, the return flow assembly 600 includes a return flow frame 610, and a plurality of rollers 620 are rotatably connected to the return flow frame 610. By placing the electrical component 700 on the rollers 620, the transportation of the electrical component 700 is realized through the rolling of the rollers 620. Among them, the return flow frame can be set as a ramp structure, so that the height of the side of the return flow assembly 600 close to the discharger 100 is lower than that of the side of the return flow assembly 600 far from the discharger 100, so that the electrical component 700 rolls along the rollers 620 under the action of gravity.

[0082] See Figure 2 and Figure 7 As shown, in some implementation manners, an operation indicator light 570 is provided on the frame. The operation indicator light 570 is electrically connected to the incoming material detection sensor 540.
