Description

Technical Field

[0001] The utility model mainly relates to the technical field of capacitors, in particular to a testing mechanism of a seat plate machine. Background Art

[0002] With the development of electronic technology, the market demand for capacitors is increasing, and the requirements for the efficiency and stability of capacitor production equipment are also increasing. Capacitor seat plate detection and packaging is a process in the capacitor production process. The existing capacitor seat plate detection and packaging is generally achieved by a fully automatic capacitor seat plate machine. The capacitor seat plate machine on the market now generally adopts a single capacitor assembly line processing method, and its processes include bare product loading, polarity detection, first foot cutting, lead flattening, seat plate, second foot cutting, printing, detection, packaging, etc.

[0003] For example, Chinese patent publication number CN209282058U discloses a capacitor seat plate capacitor bare product pin shaping mechanism, including an action component, a connecting rod driving module and a shaping head, the action component includes a power module and a shaping module, the power module includes a power block and a driving seat, the driving seat is connected to the front end of the power block through an elastic member, and a limited stop block is arranged in front of the driving seat; the shaping module includes a shaping block and a shaping neutron, the shaping neutron is fixed on the driving seat, the two shaping blocks are both rotatably connected to the driving seat, a force arm is connected between the shaping block and the power block, the force arm is rotatably connected to the power block and the shaping block respectively, and the connection point of the force arm and the shaping block is located outside the connection point of the shaping block and the driving seat; the shaping head is arranged in front of the shaping module, and the connecting rod driving module drives the power module to reciprocate.

[0004] The above application adopts a purely mechanical shaping method, which can realize the separation of the cross pins and the shaping of the bent pins, with high work efficiency, good stability, compact structure and low cost. However, the capacitor base plate machines in the prior art cannot test the capacitor directly on the base plate machine, and need to be transferred to the test equipment for testing. If the storage environment is not appropriate, it is easy to cause the pins of the capacitor to oxidize, and the oxide layer will form an insulating layer on the surface of the pins, increasing the resistance of the pins. This will cause the resistance of the current passing through the pins to increase during the test, thereby affecting the charge and discharge characteristics of the capacitor and the accuracy of the test results. The oxide layer may cause poor contact between the pins and the test instrument or circuit. The resistance change and poor contact caused by oxidation may cause an increase in the measurement error of the test instrument. This may cause the test results to deviate from the true value, misleading circuit design and performance analysis. Utility Model Content

[0038] Working principle:

[0039] Feeding mechanism 3 transfers the capacitor (at this time, Figure 7 The capacitor is first placed on the bending block 55, and then pressed down. Under the action of the bending block 55 and the first forming groove 56, the capacitor is bent into the following shape: Figure 7 In the middle b state, after the bending is completed, the return spring 57 drives the bending block 55 to return to its original position. During the rising and falling process, the first slider 53 and the second slider 58 move in the first slide groove 52 and the second slide groove 59 respectively, and at the same time serve as a guide mechanism to ensure the stability of operation.

[0040] The lifting turntable 2 transfers the capacitor to the second forming block 62, the main body of the capacitor is placed in the avoidance groove 63, and the pins of the capacitor are respectively placed in the second forming groove 64. The lifting turntable 2 drives the capacitor to be pressed down and bent into the following shape: Figure 7 Medium c status.

[0041] The lifting turntable 2 continues to drive the capacitor to the shearing table 75 of the shearing mechanism 7. The first lifting cylinder 72 drives the two shearing knives 74 to move downward through the lifting block 73 to shear the pins. Figure 7In the lifting process of the lifting block 73, the first guide rail 76 and the third slide block 77 serve as a guide mechanism to ensure the stability of the operation.

[0042] After the shearing is completed, the lifting turntable 2 transfers the capacitor to the placement table 805, and the piston rod of the second lifting cylinder 808 drives the lifting cone 809 to descend. The two horizontal slides 802 are relatively close to each other under the action of the tension spring 811, thereby driving the test pen 806 to contact the end of the capacitor pin. Figure 7 The capacitor is in the middle e state and is tested by the test mechanism 9, such as the nominal capacitance value test, leakage current test or withstand voltage test. After the test, the piston rod of the second lifting cylinder 808 drives the lifting cone 809 to rise, pushes open the two rollers 807, and makes the test pen 806 leave the pin of the capacitor. The lifting turntable 2 then transfers the capacitor to other stations of the base plate machine.

[0043] The utility model can bend the pins of the capacitor by setting the first bending mechanism 5 and the second bending mechanism 6, and then immediately test the capacitor on the test bench 8 after the pins are sheared by the shearing mechanism 7, so as to ensure that the capacitor is tested before the pins are oxidized, which helps to avoid test errors caused by oxidation of the pins and more accurately detect the quality and performance of the capacitor.
