Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a capacitor discharge testing device. Background Technology

[0002] In the production and performance testing of capacitors, repeated charge-discharge tests are a key method for evaluating core performance characteristics such as capacitance, charge-discharge life, and leakage current. In existing technologies, capacitor charge-discharge testing equipment typically requires electrical connection between the test terminals and the capacitor's electrodes to establish the continuity of the charging and discharging circuits.

[0003] Currently, most capacitor discharge testing equipment on the market is of the manual plug-and-play type. The operation of this type of equipment relies entirely on manual intervention. During testing, operators must manually press the test plate to complete the charging or discharging process. This not only easily leads to poor contact due to hand tremors during the connection process, causing unstable resistance in the charging and discharging circuit and resulting in fluctuating current, but also makes the test data prone to deviation. Furthermore, prolonged and repetitive pressing operations can easily cause hand fatigue, further exacerbating the deviation in contact position. This results in extremely poor repeatability of test results for the same batch of capacitors, making it difficult to form a reliable basis for performance evaluation.

[0004] In addition, after a single test is completed, the operator must first manually loosen the test board to disconnect from the test terminal, then pull out the connection between the capacitor electrode and the test terminal, and then remove and place the capacitor. After replacing the new test sample, the electrode and test terminal must be re-aligned and the test board pressed to complete the docking. The steps are cumbersome and time-consuming, resulting in low overall testing efficiency. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A capacitor discharge testing device, comprising:

[0008] Test socket;

[0009] The testing mechanism includes a first test board, a second test board, test terminals, and a first driving component. The first test board and the second test board are movably connected to the test base. The first test board and the second test board are spaced apart in a first direction to form a test interval. The test terminals are installed in the test interval.

[0010] The first test board is provided with a first terminal, and the second test board is provided with a second terminal. Both the first terminal and the second terminal are used to be electrically connected to the test terminal.

[0011] The first driving member is used to drive the first test board and the second test board to move closer to or away from the test terminal.

[0012] Furthermore, the first driving member includes a driving cylinder and a piston rod, the piston rod extending along the first direction, and the driving cylinder is used to drive the piston rod to reciprocate along the first direction to move closer to or further away from the test terminal.

[0013] The piston rod is connected to one end of the first test plate, and the other end of the first test plate is connected to the second test plate via a connecting rod.

[0014] Furthermore, the test seat is provided with a limiting block, and the connecting rod is movably inserted through the limiting block; both the first test plate and the second test plate are used to abut against the limiting block.

[0015] Furthermore, the test seat is provided with two limiting blocks, which are spaced apart in the second direction. There are two connecting rods, and the two ends of the two connecting rods are respectively connected to the first test plate and the second test plate. The two connecting rods are respectively inserted into the two limiting blocks.

[0016] Furthermore, the first terminal is movably connected to the first test board via a first elastic element, and the first terminal is disposed opposite to the test terminal.

[0017] Furthermore, the second terminal is movably connected to the second test board via a second elastic element, and the second terminal is disposed opposite to the test terminal.

[0018] Furthermore, the test socket has a first side and a second side that are opposite to each other, and two test terminals are provided, which are spaced apart in a second direction; the test terminals are installed on the first side, and the test terminals are provided with electrical connection terminals, which pass through the test socket and are located on the second side;

[0019] The first test board is provided with two first terminals, and the two first terminals are correspondingly arranged with the two test terminals; the second test board is provided with two second terminals, and the two second terminals are correspondingly arranged with the two test terminals.

[0021] Furthermore, the test stand is provided with a fixed base, and the first driving member is connected to the fixed base.

[0022] Furthermore, the capacitor discharge testing device includes a controller, which is electrically connected to the first driving element.

Then, the charging or discharging operation of the test terminals is completed through the first terminal on the first test plate and the second terminal on the second test plate, so as to perform performance testing on the capacitor connected to the test terminals.

[0024] Compared to manually pressing the test boards, the drive mechanism moves both test boards, reducing contact problems caused by hand tremors. This stabilizes the resistance of the charging or discharging circuit, reduces current fluctuations, effectively lowers the error rate of test data, and improves the reliability of the test equipment's output results. Furthermore, after testing, the drive mechanism automatically moves the test boards away from the test terminals, eliminating the need for manual disconnection. This simplifies the process of removing and placing capacitors and connecting them after replacement, solving the problem of cumbersome and time-consuming manual plugging and unplugging procedures, and effectively improving the overall efficiency of capacitor testing.

[0036] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0037] See Figures 1 to 3 This utility model discloses a capacitor discharge testing device, including a test base 10 and a testing mechanism. The testing mechanism includes a first test plate 20, a second test plate 30, a test terminal 11, and a first driving member 40. The first test plate 20 and the second test plate 30 are movably connected to the test base 10 and are spaced apart in a first direction to form a test interval. The test terminal 11 is installed in the test interval. The first test plate 20 is provided with a first terminal 21, and the second test plate 30 is provided with a second terminal 31. Both the first terminal and the second terminal are used to electrically connect to the test terminal 11. The first driving member 40 is used to drive the first test plate 20 and the second test plate 30 to move closer to or away from the test terminal 11.

[0038] Based on the above structure, taking the first direction as the vertical direction as an example, during assembly, the test terminal 11 is fixed at the test interval, and the test terminal 11 is respectively set with the first terminal 21 and the second terminal 31, and the test terminal 11 is connected to the terminal of the capacitor; at the same time, the first terminal 21 is electrically connected to the external power supply through the wire to provide energy input for the charging process; the second terminal 31 on the second test board 30 is connected to the short circuit 80 or the discharge resistor to form a discharge circuit.

[0039] During testing, the operator first aligns the capacitor electrodes with the test terminal 11 and completes the docking (a positioning structure can be used to achieve rapid positioning). After starting the drive mechanism, the first test plate 20 moves towards the test terminal 11 along the first direction until the first terminal 21 and the test terminal 11 are stably in contact. At this time, the current from the external power supply is quickly transferred to the capacitor through the first terminal 21 and the test terminal 11, achieving directional charging. Because the vertical driving force provided by the drive mechanism is stable and controllable, the contact state is not affected by external forces during the charging process, ensuring that the charging circuit remains unobstructed.

[0040] After charging is complete, the drive mechanism drives the first test board 20 vertically away from the test terminal 11, while simultaneously driving the second test board 30 vertically towards the test terminal 11, until the second terminal 31 is stably in contact with the test terminal 11. The electrical energy stored in the capacitor is then rapidly released through the second terminal 31 and the short circuit 80 (or discharge resistor), completing the discharge test. After a single test, the drive mechanism resets the second test board 30. The operator can then remove the old capacitor, replace it with a new sample, and repeat the above test procedure.

[0041] Compared to the problem of poor contact caused by hand tremors when manually pressing the test board, this embodiment uses a drive mechanism to move the first test board 20 or the second test board 30 along a preset trajectory (first direction) close to the test terminal 11. The drive mechanism provides a stable and controllable driving force to keep the contact state between the first terminal 21, the second terminal 31 and the test terminal 11 consistent, reducing the risk of resistance fluctuations in the charging and discharging circuit caused by changes in the contact gap, reducing the problem of fluctuating current, and making the test data more stable.

[0042] Furthermore, the drive mechanism automatically moves the test board closer to and further away, eliminating the need for manual control of contact and disconnection. This effectively shortens the auxiliary operation time for a single test and improves overall testing efficiency. Moreover, the entire charging and discharging process is automatically controlled by the drive mechanism, reducing contact deviations caused by human operator fatigue and further enhancing the stability and reliability of the test.

[0043] It should be noted that the driving mechanism in this embodiment can be an existing dual-output shaft cylinder. This driving mechanism includes a cylinder body, a first output shaft (piston), and a second delivery shaft (piston). During assembly, the first and second output shafts are respectively arranged along a first direction. The top end of the first output shaft is fixedly connected to the bottom of the first test plate 20 by bolts, and the top end of the second output shaft is fixedly connected to the bottom of the second test plate 30 by bolts. Simultaneously, vertical guide rails (such as linear guides) are provided on both sides of the test plate, and the sides of the test plate slide in cooperation with the rails via sliders. Furthermore, the cylinder body has two independent air chambers. By controlling the air path switching through a solenoid valve, the two output shafts can be driven to extend or retract respectively, thereby causing the first test plate 20 and the second test plate 30 to move closer to or further away from the test terminal 11.

[0044] Of course, a single-axis cylinder can also be used as the drive mechanism. The output shaft (piston) of the single-axis cylinder extends vertically, and the first test plate 20 and the second test plate 30 are fixed in series along the axis of the output shaft. For example, the first test plate 20 is directly fixed to the middle position of the output shaft with bolts, and the second test plate 30 is fixed to the top (or bottom) of the output shaft with bolts. A preset distance is maintained between the two test plates (the distance must be greater than the height of the test terminal 11 so that the two test plates will not contact the test terminal 11 at the same time, and will not cause motion interference due to too small a distance). The test terminal 11 is fixed on the vertical axis between the two test plates. Taking the first test plate 20 located in the middle of the output shaft and the second test plate 30 located at the top of the output shaft as an example:

[0045] When the output shaft extends towards the middle test terminal 11 in the first direction (e.g., downward), it drives the second test plate 30 at the top and the first test plate 20 in the middle to move downward synchronously. Since the initial position of the second test plate 30 is above the test terminal 11, when it extends downward to its limit position with the output shaft, it will pass over the test terminal 11 and continue downward, eventually ending below the test terminal 11 (the second terminal 31 is away from the test terminal 11); while the first test plate 20 in the middle moves to a position aligned with the test terminal 11. At this time, the first terminal 21 and the middle test terminal 11 are stably abutted, and the charging circuit is connected.

[0046] When discharging the capacitor, the output shaft retracts upwards along the first direction, simultaneously driving the two test plates upwards. At this time, the first test plate 20 in the middle moves upwards with the output shaft, so that the first terminal block disengages from the test terminal 11; the second test plate 30 at the top moves from below the test terminal 11 to a position aligned with the test terminal 11. When the output shaft retracts to the preset stroke, the second terminal block 31 and the middle test terminal 11 are stably abutted, and the discharge circuit is connected.

[0047] Of course, the first test plate 20 and the second test plate 30 can also be connected in series by a connecting rod to achieve the same effect, which will not be elaborated on here.

[0048] Specifically, in this embodiment, the first terminal 21 and the second terminal 31 can be made of copper with conductive properties, such as spring-type terminals, pin-type terminals (such as copper pins), or copper rods.

[0049] Alternatively, the test terminal 11 can adopt a clip-on structure, consisting of two symmetrical phosphor bronze metal clips. The elastic properties of phosphor bronze allow the clip spacing to match the thickness of the capacitor electrodes. The bottom of the clips is fixed to a preset position on the equipment by an insulating bracket. During docking, the operator directly inserts the capacitor electrodes between the clips, which then clamp the electrodes using their own elasticity, achieving positioning without additional fasteners. Alternatively, the test terminal 11 can also adopt a conductive metal block (such as a copper block) structure. Slots matching the capacitor electrodes (slot depth and width corresponding to electrode dimensions) are provided on the surface of the metal block. During docking, the capacitor electrodes are inserted into the slots, and the mechanical restraint of the slots achieves fixation.

[0050] Furthermore, the first driving member 40 includes a driving cylinder 41 and a piston rod 42. The piston rod 42 extends along a first direction. The driving cylinder 41 is used to drive the piston rod 42 to reciprocate along the first direction to move closer to or further away from the test terminal 11. The piston rod 42 is connected to one end of the first test plate 20, and the other end of the first test plate 20 is connected to the second test plate 30 through a connecting rod 50.

[0051] Based on this structure, during assembly, the piston rod 42 of the drive cylinder extends along the first direction (such as the vertical direction), and the end of the piston rod 42 is fixedly connected to the first test plate 20; the first test plate 20 and the second test plate 30 are distributed vertically at intervals in the first direction, and the two are rigidly fixed by the connecting rod 50 (the two ends of the connecting rod 50 are respectively connected to the same side edge of the two test plates), so that the two test plates form a "vertically linked" whole. When the piston rod 42 moves along the first direction, it can synchronously drive the two to move in the same direction.

[0052] When the capacitor is being charged, the drive cylinder 41 is activated, and the piston rod 42 extends downward in the first direction, driving the first test plate 20 to approach the test terminal 11 until the first terminal 21 and the test terminal 11 are stably in contact. At this time, the second test plate 30 located below moves downward synchronously with the connecting rod 50. Because there is a gap between its initial position and the test terminal 11, it eventually moves away from the test terminal 11, and the charging circuit is connected and charging is completed.

[0053] When discharging the capacitor, the drive cylinder 41 drives the piston rod 42 to retract upward in the first direction. The first test plate 20 retracts synchronously with the piston rod 42, and the first terminal 21 is disconnected from the test terminal 11 (the charging circuit is disconnected). At the same time, the second test plate 30 moves upward with the piston rod 42 and gradually approaches the test terminal 11 until the second terminal 31 is stably in contact with the test terminal 11, the discharge circuit is turned on and the discharge is completed.

[0054] Furthermore, the test seat 10 is provided with a limiting block 12, and the connecting rod 50 is movably inserted through the limiting block 12; the first test plate 20 and the second test plate 30 are both used to abut against the limiting block 12.

[0055] Specifically, when the piston rod 42 extends to the position where the first terminal 21 abuts against the test terminal 11, the edge of the first test plate 20 abuts against one side of the limiting block 12. At this time, the driving force is supported by the limiting block 12, reducing the risk of a "hard collision" between the first terminal 21 and the test terminal 11 due to excessive extension of the piston rod 42. Similarly, when the piston rod 42 retracts to the position where the second terminal 31 abuts against the test terminal 11, the edge of the second test plate 30 abuts against the other side of the limiting block 12. The retraction stroke is also limited by mechanical blocking, so that the abutting force between the second terminal 31 and the test terminal 11 is always consistent (the contact pressure will not fluctuate due to excessive thrust of the piston rod 42).

[0056] In addition, during assembly, a guide hole can be provided on the limiting block 12. After the connecting rod 50 is passed through the guide hole of the limiting block 12, the limiting block 12 can constrain the movement trajectory of the connecting rod 50. When the piston rod 42 drives the connecting rod 50 to move along the first direction, the guide hole can limit the horizontal sway of the connecting rod 50, so that the first test plate 20 and the second test plate 30 always move smoothly along the first direction, reducing the horizontal deviation when the two terminals are connected to the test terminal 11.

[0057] More specifically, in this embodiment, the test base 10 is provided with two limiting blocks 12, which are spaced apart in the second direction (such as the horizontal direction of the test base 10). Simultaneously, two connecting rods 50 are also provided, with their ends connected to the first test plate 20 and the second test plate 30 respectively. The two connecting rods 50 pass through the two limiting blocks 12. By distributing the two connecting rods 50 at intervals along the second direction, and cooperating with the guide holes of the corresponding limiting blocks 12, a "two-point positioning" constraint structure is formed. Compared to a single connecting rod 50, two connecting rods 50 can more comprehensively restrict the rotation or offset of the first test plate 20 and the second test plate 30 in the horizontal direction (such as the tilting tendency of the first test plate 20 due to uneven force), reducing the fluctuation in the contact area between the two terminals and the test terminal 11 caused by unilateral shaking, and further improving docking stability.

[0058] Furthermore, the first terminal 21 is movably connected to the first test plate 20 via the first elastic member 22, and the first terminal 21 is arranged opposite to the test terminal 11.

[0059] Specifically, during assembly, the first terminal 21 is movably connected to the first test plate 20 via the first elastic element 22 (such as a compression spring or elastic copper sheet), and the first terminal 21 and the test terminal 11 are kept in relative positions. When the first test plate 20 approaches the test terminal 11 under the drive of the piston rod 42, if the docking speed is too fast due to stroke control error, the first elastic element 22 will absorb part of the impact force through compression (instead of rigidly transmitting it to the test plate or test terminal 11), thereby reducing the wear rate of the first terminal 21 and the test terminal 11.

[0060] In addition, the buffering effect of the first elastic element 22 can reduce the vibration when the test plate and the limiting block 12 come into contact, and reduce the problem of the connected terminals temporarily disengaging due to instantaneous vibration.

[0061] Similarly, the second terminal 31 is movably connected to the second test plate 30 via the second elastic element 32, and the second terminal 31 is positioned opposite to the test terminal 11. When the second test plate 30 approaches the test terminal 11 under the drive of the piston rod 42, if the docking speed is too fast due to stroke control error, the second elastic element 32 (such as a compression spring or elastic copper sheet) will absorb part of the impact force through compression (rather than rigidly transmitting it to the test plate or test terminal 11), reducing the wear rate of the second terminal 31 and the test terminal 11. Moreover, at the moment when the second test plate 30 abuts against the limit block 12, the second elastic element 32 can play a shock-absorbing role, reducing the problem of the second terminal 31 and the test terminal 11 temporarily disengaging due to vibration.

[0062] Furthermore, the test socket 10 has a first side 13 and a second side 14 that are opposite to each other, and two test terminals 11 are provided, which are spaced apart in a second direction; the test terminals 11 are installed on the first side 13, and the test terminals 11 are provided with electrical connection terminals 111, which pass through the test socket 10 and are located on the second side 14; the first test plate 20 is provided with two first wiring terminals 21, which are correspondingly provided with the two test terminals 11; the second test plate 30 is provided with two second wiring terminals 31, which are correspondingly provided with the two test terminals 11.

[0063] Based on this structure, during assembly, the test base 10 has a first side 13 (such as the front) and a second side 14 (such as the back) that are opposite to each other. Two test terminals 11 are spaced apart in the second direction (horizontal direction) and are both fixed to the first side 13 of the test base 10. Each test terminal 11 is provided with an electrical connection terminal 111. The two electrical connection terminals 111 are located on the second side 14 and are used to connect the terminals of an external capacitor so that the connection position of the capacitor is completely separated from the movement area of ​​the test plate on the first side 13, avoiding movement interference between the capacitor and the test plate and the connecting rod 50, and further reducing the risk of poor contact caused by collision with external components.

[0064] In addition, two test terminals 11, two first terminals 21, and two second terminals 31 are provided, so that the two electrodes of a single capacitor can be connected to the two test terminals 11 respectively. During charging, the two first terminals 21 are simultaneously brought into contact with the test terminals 11, and during discharging, the two second terminals 31 are simultaneously connected. Compared with the single-terminal design, it is not necessary to test the positive and negative terminals of the capacitor twice. The complete test of the two terminals of the capacitor can be completed in a single charge and discharge, which greatly shortens the test cycle of a single capacitor.

[0065] Furthermore, the capacitor discharge testing device includes a clamping mechanism 60, which is mounted on the second side 14. The clamping mechanism 60 includes a clamping member 61 and a second driving member 62. The clamping member 61 is spaced apart from the two test terminals 11 and can move closer to or away from the test terminals 11. The second driving member 62 is used to drive the clamping member 61 to move closer to or away from the electrical connection terminal 111 test terminal 11.

[0066] Specifically, when the operator connects the capacitor electrode to the electrical connection terminal 111 of the test terminal 11, the second driving member 62 drives the clamping member 61 to approach the test terminal 11 until the clamping member 61 abuts against the capacitor housing or non-electrode part to lock the capacitor and reduce the displacement of the capacitor due to vibration or equipment operation impact during charging and discharging (such as the electrode coming loose from the electrical connection terminal 111).

[0067] More specifically, the second drive unit 62 automatically clamps or releases the capacitor, reducing the auxiliary time for manual fixing and improving the overall testing efficiency.

[0068] It should be noted that the second driving component 62 can be a readily available cylinder. The cylinder's output shaft (piston) is fixedly connected to the clamping component 61 (such as a flat clamping plate or an arc-shaped clamping block adapted to the shape of the housing), and a stable driving force is provided by the cylinder. When the output shaft extends, the clamping component 61 moves closer to the capacitor and applies a continuous clamping force; after the test, the output shaft retracts, the clamping component 61 disengages from the capacitor, and the operator can easily remove the sample.

[0069] Furthermore, the test stand 10 is provided with a fixed base 15, and the first driving member 40 is connected to the fixed base 15.

[0070] Specifically, when the first driving component 40 drives the test plate to reciprocate, it will generate a periodic reaction force (especially at the moment when the test plate abuts against the limit block 12). Since the first driving component 40 is fixedly connected to the fixed base 15, the fixed base 15 can provide a rigid support foundation for the first driving component 40, and the reaction force can be directly transmitted to the test base 10 (instead of being borne only by its own fixed point), reducing the loosening or displacement of the first driving component 40 due to long-term stress.

[0071] More specifically, the capacitor discharge testing device includes a controller 70, which is electrically connected to the first drive member 40. The controller 70 controls the extension or retraction of the piston rod 42 of the first drive member 40 to achieve automated control without manual intervention, thus effectively improving testing efficiency.

[0072] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
