Specific embodiments

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0034] Embodiment: Refer to Figures 1-9 , a detection device for improving the consistency of capacitor grouping, including a base 1 with a mounting plate 11 fixedly installed at the top. A conveyor for transmitting capacitors is provided on the mounting plate 11, and a support plate 12 for supporting the conveyor is fixedly installed inside the mounting plate 11; a detection part 4 for detecting capacitors is arranged on the mounting plate 11 in a lifting manner; a rectangular circulating guide rail 31 connected end to end is arranged on the mounting plate 11, and a clamping part 7 is arranged on the conveyor in a lifting manner. The bottom of the clamping part 7 first drags the pins of the capacitor along the slope of the rectangular circulating guide rail 31 and then jacks up the pins of the capacitor; a guide plate 75 is fixedly installed on the mounting plate 11. When the clamping part 7 moves along with the conveyor, the guide plate 75 adjusts the frictional resistance between the clamping part 7 and the capacitor pins.

[0035] In this component, the worker or the loading device can insert the rectangular capacitor onto the conveyor at the loading end of the conveyor. During the process of the conveyor transporting the rectangular capacitor, the clamping part 7 and the guide plate 75 cooperate to clamp the pins of the rectangular capacitor, and then intermittently move to the bottom of the detection part 4. While using the detection part 4 to detect the surface and performance of the capacitor, the clamping part 7 descends under the action of the rectangular circular guide rail 31. During this process, the clamping part 7 drags the pins of the rectangular capacitor to detect the connection stability of the pins of the rectangular capacitor. After the detection is completed, under the action of the rectangular circular guide rail 31 and the guide plate 75, the clamping part 7 drives the pins to rise and then release. When the rectangular capacitor is transported to the lower part of the conveyor, under the action of gravity, the capacitor drops into the discharge hopper on the base 1.

[0036] Refer to Figure 1 、 Figure 7 and Figure 9 As shown in FIGS.

[0037] When in use, the motor 2 drives the driving gear 22 to rotate through the rotating shaft 21. The driving gear 22 drives the flexible transmission strip 23 to rotate circularly on the support plate 12. The flexible transmission strip 23 drives the limiting plate 13 to move, and further drives the rectangular capacitor inserted on the limiting plate 13 to move.

[0038] Refer to Figure 6 As shown in FIG.

[0039] The detection part 4 includes an electric telescopic cylinder 41 fixedly installed on the outer wall of the mounting plate 11. The output end of the electric telescopic cylinder 41 is fixedly installed with a mounting frame 42. The mounting frame 42 is fixedly installed with a vision detector 43 and a detection probe 44.

[0040] Refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 8, an installation wheel 3 is fixedly installed on the installation plate 11, a rectangular circulating guide rail 31 is fixedly installed on the installation wheel 3, a sunken guide rail 32 lower than both ends is arranged at the top of the rectangular circulating guide rail 31, and both ends of the sunken guide rail 32 are connected to both ends of the rectangular circulating guide rail 31 through symmetrical inclined guide rails 33. Among them, the convex surface of the guide plate 75 in contact with the clamping part 7 is longer than the sunken guide rail 32. The clamping part 7 includes a sliding rod 76 slidably installed on the limiting plate 13. An installation box 71 is fixedly installed at the bottom of the sliding rod 76. Installation pipes 73 are slidably installed at both ends of the installation box 71. The installation pipes 73 extend into the installation box 71 and are fixedly installed with clamping plates 72. A tension spring 77 with both ends fixedly connected to the installation box 71 and the clamping plate 72 respectively is arranged in the installation box 71. One end of the installation pipe 73 extending outside the installation box 71 is fixedly installed with a universal ball seat 74, and the universal ball seat 74 abuts against the guide plate 75.

[0041] When in use, the universal ball seat 74 first contacts the inclined surface of the guide plate 75. During the mobile process, through the inclined surface of the guide plate 75, the two installation pipes 73 drive the clamping plate 72 to move towards the inside of the installation box 71 and stretch the tension spring 77. The clamping plate 72 and the installation box 71 cooperate to clamp the pins of the rectangular capacitor.

[0042] When the universal ball seat 74 passes through the inclined surface at the other end, under the guidance of the inclined surface and the rebound of the tension spring 77, the installation pipe 73 moves towards the outside of the installation box 71, thereby loosening the pins.

[0043] Refer to Figure 2 、 Figure 5 and Figure 6 , a limiting pipe 83 is slidably installed in the installation pipe 73. A measuring plate 81 is fixedly installed at the end of the limiting pipe 83. A second spring 82 is sleeved on the limiting pipe 83. Both ends of the second spring 82 are in contact connection with the limiting pipe 83 and the measuring plate 81 respectively. A detection contact 8 is fixedly installed on the limiting plate 13. The detection contact 8 is connected to the measuring plate 81 through a wire 84.

[0044] When the clamping part 7 clamps the pins, the measuring plate 81 abuts against the pins under the action of the second spring 82, and then the detection probe 44 of the detection part 4 contacts the detection contact 8, realizing the detection connection between the detection probe 44 and the detection contact 8.

[0045] Refer to Figure 3 and Figure 5, further comprising a mounting base 5, the mounting base 5 includes a first mounting cylinder 51, a limiting wheel 52 that rotates on the side wall of the first mounting cylinder 51 and moves along the rectangular circulating guide rail 31 is rotatably mounted, a first piston plate 53 is slidably mounted in the first mounting cylinder 51, a mounting column 54 is fixedly mounted on the top of the first piston plate 53, a first spring 55 with two ends respectively abutted against the first mounting cylinder 51 and the first piston plate 53 is sleeved on the mounting column 54, the mounting column 54 is connected to the mounting box 71 through a connecting part 6, the connecting part 6 includes an air box 61 fixedly mounted on the top of the mounting column 54, a second mounting cylinder 62 is fixedly mounted on the top of the air box 61, the top of the second mounting cylinder 62 is fixedly connected to the mounting box 71, a second piston plate 95 is slidably mounted in the second mounting cylinder 62, a push rod 94 is fixedly mounted on the second piston plate 95, a third spring 9 with two ends respectively abutted against the mounting box 71 and the second piston plate 95 is sleeved on the push rod 94, an air hole 91 communicating with the internal air cavity of the first mounting cylinder 51 is arranged in the mounting column 54, one-way valves are arranged at the air inlet end of the first mounting cylinder 51 and the exhaust end of the air hole 91, an exhaust control valve 93 is arranged on the air box 61, the exhaust end of the exhaust control valve 93 is communicated with the air box 61 through an air pipe 92, when the limiting plate 13 faces downwards, the exhaust control valve 93 is opened.

[0046] When the conveyor drives the limiting plate 13 to move, the limiting wheel 52 moves along the rectangular circulating guide rail 31. When the limiting wheel 52 moves along the upper part of the rectangular circulating guide rail 31, it first descends along the inclined guide rail 33, then translates on the sunken guide rail 32, and then moves up along the inclined guide rail 33 at the other end after detection. Among them, the clamping part 7 moves along the moving track of the limiting wheel 52.

[0047] When the limit wheel 52 passes through the inclined guide rail 33 for the first time within a cycle, if the connection between the pin and the rectangular capacitor is stable at this time, then the first spring 55 contracts, the first piston plate 53 rises, and under the action of the one-way valve, external gas is inhaled into the first installation cylinder 51. When the universal ball seat 74 passes through the second inclined plane of the guide plate 75 within a cycle, under the elastic return action of the tension spring 77, the clamping plate 72 disengages from the pin of the measuring plate 81. Then, when the limit wheel 52 passes through the inclined guide rail 33 and rises for the second time, driven by the elastic return of the first spring 55, the first piston plate 53 descends within the first installation cylinder 51, and the gas in the first installation cylinder 51 is transmitted through the air hole 91 and the trachea 92 to the air box 61 for partial flow, and then drives the second piston plate 95 to rise and makes the third spring 9 contract. The second piston plate 95 drives the ejector rod 94 to rise, and the ejector rod 94 drives the pin to rise to prevent the pin from being adsorbed by the installation box 71. When the rectangular capacitor faces downward, the rectangular capacitor disengages from the installation box 71 and the limit plate 13 under the action of gravity. At the same time, the spherical valve core inside the exhaust control valve 93 disengages from the exhaust port under the action of gravity, making the air box 61 communicate with the outside. At this time, the third spring 9 rebounds to reset the second piston plate 95 and the ejector rod 94. When the limit plate 13 faces upward again, the spherical valve core blocks the exhaust port of the air box 61 again under the action of gravity.

[0048] When the connection between the pin and the capacitor is unstable, when the clamping part 7 descends, it will pull out the pin from the rectangular capacitor.

[0049] As Figure 10 shown, there is a groove provided on the concave guide rail 32. When the limit wheel 52 passes through the groove, it causes the first installation cylinder 51 to vibrate up and down, thereby simulating the stability of the capacitor after being installed on the circuit board when passing through a bumpy environment.

[0050] In summary, the device has the following advantages:

[0051] When the clamping part 7 of the device descends along the inclined guide rail 33, the clamping plate 72 exerts a horizontal dragging force on the pin, simulating the lateral friction stress when the capacitor is inserted into the PCB. When the limit wheel 52 passes through the groove on the concave guide rail 32, it triggers the first installation cylinder 51 to vibrate up and down, simulating the bumpy environment of the circuit board, and further verifying the stability of the pin under dynamic working conditions.

[0052] The device uses the flexible transmission strip 23 to drive the limit plate 13 to move linearly in a cycle. The detection part 4 (vision detector 43 + multiple groups of detection probes 44) completes the appearance test, electrical performance test (capacitance / resistance / voltage withstand, and in addition, probes for other electrical performance tests such as short-circuit test probes can be installed according to needs) and pin strength test at one time. In addition, while the clamping part 7 drags the pin under the control of the guide rail, the detection probe 44 obtains real-time electrical data through the detection contact 8, avoiding multiple positioning errors.

[0053] In this device, the motor 2 drives the entire transmission system through the flexible transmission strip 23. The electric telescopic cylinder 41 controls the lifting of the detection unit 4. There is no redundant power unit. The clamping part 7 realizes clamping / releasing through the guide rail slope (tilted guide rail 33), the tension spring 77 and the inclined plane of the guide plate 75. The jacking action is completed by the springs (the first spring 55, the third spring 9) and the exhaust control valve 93 that relies on gravity to adjust the connection or disconnection, reducing the energy consumption during the capacitance detection process.

[0054] The above are only the preferred embodiments of the present invention, and there is no limitation to the present invention in any form. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the technical content prompted above within the scope of the technical solution of the present invention.
