Description

Technical Field

[0001] This application belongs to the field of capacitance testing technology, specifically relating to a calibration mechanism and calibration device. Background Technology

[0002] Before testing a horn capacitor, a camera is needed to capture the pin position information. Then, the capacitor is clamped and rotated using a motor to calibrate its pins to the preset positions. Finally, the capacitor pins are inserted into the clamping gaps on the capacitor test socket. Because the pin position information captured by the camera has some error, and the motor's rotation angle also has some error, some horn capacitor pins may not be calibrated to the required preset positions. This can lead to the capacitor pins not being accurately inserted into the clamping gaps on the capacitor test socket, causing collisions between the capacitor pins and the test socket, potentially damaging both the capacitor and the test socket. Summary of the Invention

[0043] The calibration mechanism and calibration device provided in this application are used to calibrate capacitors. This application uses the calibration of a horn capacitor as an example for illustration. It can be understood that the calibration mechanism and calibration device can also calibrate other capacitors.

[0044] Firstly, embodiments of this application provide a calibration mechanism, please refer to... Figures 2 to 5 The calibration mechanism 100 includes a drive assembly 20 and at least two clamping assemblies 10. Each clamping assembly 10 includes a first clamping member 11 and a second clamping member 12 disposed opposite each other along a first direction Y. A clamping space 13 is provided between the first clamping member 11 and the second clamping member 12, and the clamping space 13 is used to accommodate the first pin 401 and / or the second pin 402 of the capacitor 400. At least two clamping assemblies 10 are distributed along a second direction X, such that the first pin 401 and the second pin 402 are arranged along the second direction X, which is perpendicular to the first direction Y. The drive assembly 20 is used to drive the first clamping member 11 and the second clamping member 12 to move closer to or further away from each other.

[0045] The capacitor 400 includes a body 403 and pins protruding from the body 403. Optionally, the capacitor 400 is a horn capacitor, with the first pin 401 and the second pin 402 being the positive and negative terminals of the capacitor 400, respectively. The capacitor 400 can also be other types of capacitors 400 with pins, and the first pin 401 and the second pin 402 can also be other pins besides electrodes, such as pins that have a supporting or connecting function.

[0046] Each clamping assembly 10 includes a first clamping member 11 and a second clamping member 12, which are spaced apart along a first direction Y. The first clamping members 11 and 12 are primarily used to clamp the first pin 401 and the second pin 402 of the capacitor 400. The two first clamping members 11 can be an integral structure or independently arranged; similarly, the two second clamping members 12 can be an integral structure or independently arranged. Optionally, the first clamping members 11 and 12 can be rod-shaped, block-shaped, or plate-shaped structures. The first clamping members 11 and 12 can be made of insulating material or conductive material such as metal. When the two first clamping members 11 are an integral structure, they are made of insulating material to prevent the two first clamping members 11 from conducting the first pin 401 and the second pin 402, thus preventing a short circuit in the capacitor 400. Similarly, when the two second clamping members 12 are an integral structure, they are made of insulating material. The first clamping member 11 and the second clamping member 12 can be used to support the main body 403 of the capacitor 400.

[0047] A clamping space 13 is formed between the first clamping member 11 and the second clamping member 12 in the same clamping assembly 10. Each clamping space 13 can accommodate either the first pin 401 or the second pin 402. The two clamping spaces 13 can be used to accommodate the first pin 401 and the second pin 402 respectively, meaning the two clamping assemblies 10 are used to clamp the first pin 401 and the second pin 402 respectively. For capacitors 400 where the distance between the first pin 401 and the second pin 402 is small, one clamping space 13 can also be used to accommodate both pins, meaning one clamping assembly 10 can be used to clamp both pins. Optionally, the clamping space 13 can also accommodate other pins on the capacitor 400 that are on the same straight line as the first pin 401 and the second pin 402. Optionally, the first direction Y is perpendicular to the height direction of the clamping assembly 10.

[0048] Optionally, two clamping components 10 are provided. The two clamping components 10 are distributed along the second direction X, that is, the two first clamping members 11 of the two clamping components 10 are distributed along the second direction X, and the two second clamping members 12 are distributed along the second direction X. Optionally, the second direction X is perpendicular to the height direction of the clamping components 10.

[0049] Optionally, the clamping components 10 may be configured in two or more to clamp other pins besides the first pin 401 and the second pin 402.

[0050] The drive assembly 20 can directly drive the first clamping member 11 and the second clamping member 12, or indirectly drive the first clamping member 11 and the second clamping member 12 through elastic members or the like. When the drive assembly 20 directly drives the first clamping member 11 and the second clamping member 12, the force applied by the drive assembly 20 to the first clamping member 11 and the second clamping member 12 can only push the first pin 401 and the second pin 402 through the first clamping member 11 and the second clamping member 12, and cannot cause the first clamping member 11 and the second clamping member 12 to squeeze the first pin 401 and the second pin 402, thus causing deformation of the first pin 401 and the second pin 402.

[0051] The drive assembly 20 can be configured with one drive unit to drive the first clamping member 11 and the second clamping member 12, or it can be configured with multiple drive units to drive the two first clamping members 11 and the two second clamping members 12 respectively. Optionally, the drive assembly 20 may include a gripper cylinder, a lead screw, or four cylinders. For example, when the drive assembly 20 includes a gripper cylinder, one gripper of the gripper cylinder is connected to the two first clamping members 11, and the other gripper is connected to the two second clamping members 12. For example, when the drive assembly 20 includes four cylinders, two cylinders drive the two first clamping members 11 respectively, and the other two cylinders drive the two second clamping members 12 respectively.

[0052] Optionally, in this embodiment of the application, the process of calibrating capacitor 400 is as follows: one end of the capacitor 400 body 403 with pins is placed on two clamping components 10, and the center line (axis) of capacitor 400 is aligned with the center position of the whole formed by the two clamping components 10. If the first pin 401 and the second pin 402 are respectively placed in the two clamping spaces 13, the capacitor 400 body 403 can remain stable on the clamping components 10.

[0053] After capacitor 400 is placed, the driving component 20 drives the first clamping member 11 and the second clamping member 12 to move closer to each other. The two sets of first clamping members 11 and second clamping members 12 push the first pin 401 and the second pin 402 to move. For capacitor 400 whose first pin 401 and the second pin 402 are symmetrical about the center line (axis) of capacitor 400, if the center line of capacitor 400 is aligned with the center position of the whole composed of the two clamping components 10, then the first pin 401 and the second pin 402 are symmetrical about the center position of the whole composed of the two clamping components 10. The first pin 401 and the second pin 402 are located on both sides of the center position along the first direction Y. The two clamping components 10 push the first pin 401 and the second pin 402 to move in opposite directions, so that the first pin 401 and the second pin 402 can drive capacitor 400 to rotate around the center line. When the first pin 401 and the second pin 402 move to the middle position of the clamping space 13, the first pin 401 and the second pin 402 are located on the same straight line along the second direction X.

[0054] The beneficial effects of this application embodiment are as follows: The first clamping member 11 and the second clamping member 12 are disposed on both sides of the clamping space 13, which can place the first pin 401 and the second pin 402, which have a large deviation from the preset position, on the clamping assembly 10, so that the capacitor 400 falls off the clamping assembly 10. This can avoid placing the capacitor 400, whose first pin 401 and the second pin 402 have a large positional deviation, into the test socket, thereby reducing the risk of the first pin 401 and the second pin 402 of the capacitor 400 damaging the test socket. The driving assembly 20 can drive the first clamping member 11 and the second clamping member 12 to push the first pin 401 and the second pin 402 in the clamping space 13, so that the first pin 401 and the second pin 402 can be arranged along the second direction X, so that the first pin 401 and the second pin 402 can be placed in the clamping gap 501 opened on the capacitor test socket 500, thereby reducing the risk of the first pin 401 and the second pin 402 of the capacitor 400 damaging the test socket. In summary, the embodiments of this application can solve the technical problem that collisions between the pins of the horn capacitor and the capacitor test socket 500 can easily lead to damage to both the capacitor test socket 500 and the horn capacitor.

[0055] In some embodiments, please refer to Figures 2 to 3The correction mechanism 100 further includes an elastic component 30, which abuts against the drive component 20 and the first clamping member 11 respectively, so that the drive component 20 drives the first clamping member 11 to move through the elastic component 30; and / or, the elastic component 30 abuts against the drive component 20 and the second clamping member 12 respectively, so that the drive component 20 drives the second clamping member 12 to move through the elastic component 30.

[0056] The elastic component 30 is disposed between the driving component 20 and the clamping component 10. The driving component 20 pushes the elastic component 30 closer to the first pin 401 and the second pin 402, causing the elastic component 30 to push the clamping component 10 closer to the first pin 401 and the second pin 402. The force applied by the elastic component 30 to the first clamping member 11 and the second clamping member 12 is only enough to push the first pin 401 and the second pin 402, causing the first pin 401 and the second pin 402 to move the capacitor 400, but it cannot cause deformation of the first pin 401 and the second pin 402. By designing a smaller elastic coefficient, a smaller elastic force can be controlled by the elastic component 30 applying to the clamping component 10.

[0057] The elastic component 30 includes an elastic element, which can be disposed between the driving component 20 and the first clamping member 11, or between the driving component 20 and the second clamping member 12. Alternatively, some of the elastic elements in the elastic component 30 can be disposed between the driving component 20 and the first clamping member 11, and other elastic elements can be disposed between the driving component 20 and the second clamping member 12.

[0058] Optionally, the elastic component 30 is fixedly connected to the driving component 20 and the clamping component 10 respectively. The driving component 20 can drive the clamping component 10 away from the first pin 401 and the second pin 402 through the elastic component 30.

[0059] When the elastic component 30 contacts or abuts against the drive component 20 and the clamping component 10, but is not connected to the drive component 20 and the clamping component 10, the drive component 20 cannot drive the first clamping member 11 and the second clamping member 12 away from the first pin 401 and the second pin 402 through the elastic component 30. At this time, the drive component 20 can also be connected to the clamping component 10 through other structures such as soft ropes, so as to drive the clamping component 10 away from the first pin 401 and the second pin 402.

[0060] Optionally, the elastic component 30 may include a spring, a pneumatic telescopic rod, etc.

[0061] In this embodiment, the process of clamping the first pin 401 and the second pin 402 is as follows: the two clamping components 10 respectively push the first pin 401 and the second pin 402 to move in opposite directions, thereby causing the capacitor 400 to rotate; after the clamping components 10 clamp the first pin 401 and the second pin 402, the clamping components 10 are both in contact with the first pin 401 and the second pin 402. If the driving component 20 continues to move, the elastic component 30 will be compressed and deformed, and the elastic force applied by the elastic component 30 to the clamping component 10 will increase. The force applied by the clamping component 10 to the first pin 401 and the second pin 402 will increase. Since the elastic force applied by the elastic component 30 to the clamping component 10 is small, the force applied by the clamping component 10 to the first pin 401 and the second pin 402 is small, and it is not easy to deform the first pin 401 and the second pin 402.

[0062] The beneficial effects of this application embodiment are as follows: the driving component 20 drives the clamping component 10 to move through the elastic component 30. The force of the driving component 20 cannot be directly applied to the first pin 401 and the second pin 402. The driving component 20 controls the elastic force of the elastic component 30 by controlling the deformation amount of the elastic component 30, thereby controlling the clamping force. The elastic force of the elastic component 30 can be easily controlled within a small range. By controlling the elastic force of the elastic component 30, it is convenient to control the clamping force of the clamping component 10, thereby making it convenient to control the first clamping member 11 and the second clamping member 12 to only push the first pin 401 and the second pin 402, without causing the pins to deform.

[0063] In some embodiments, please refer to Figures 2 to 3 The elastic component 30 includes a first elastic element 31 and a second elastic element 32. The first elastic element 31 abuts against the drive component 20 and the first clamping member 11, respectively, and the second elastic element 32 abuts against the drive component 20 and the second clamping member 12, respectively.

[0064] The first and second elastic elements can be arranged in various ways.

[0065] For example, the elastic component 30 includes a first elastic member 31 and a second elastic member 32. The first elastic member 31 abuts against two first clamping members 11 to push the two first clamping members 11 to move synchronously. The second elastic member 32 abuts against two second clamping members 12 to push the two second clamping members 12 to move synchronously.

[0066] For example, the elastic component 30 includes two first elastic elements 31 and two second elastic elements 32. The two first elastic elements 31 abut against two first clamping elements 11 respectively, and one first elastic element 31 pushes one first clamping element 11 to move independently. The two second elastic elements 32 abut against two second clamping elements 12 respectively, and one second elastic element 32 pushes one second clamping element 12 to move independently.

[0067] The first pin 401 and the second pin 402 of different capacitors 400 have different configurations. Please refer to [reference needed]. Figure 6 The first pin 401 and the second pin 402 are perpendicular to each other. When the first pin 401 and the second pin 402 are pushed to the middle position of the clamping space 13, the dimensions of the first pin 401 and the second pin 402 are different in the first direction Y. If the two first clamping members 11 move synchronously and the two second clamping members 12 move synchronously, there will be a situation where only one of the first pin 401 and the second pin 402 is clamped, and the clamping of the first pin 401 and the second pin 402 is not stable enough.

[0068] Two first elastic members 31 respectively push the two first clamping members 11 of the two clamping assemblies 10 to move independently, and two second elastic members 32 respectively push the two second clamping members 12 of the two clamping assemblies 10 to move independently. Before the two clamping assemblies 10 clamp the first pin 401 and the second pin 402, the two first elastic members 31 push the two first clamping members 11 to move synchronously, and the two second elastic members 32 push the two second clamping members 12 to move synchronously. When the first clamping assembly 10 clamps the larger first pin 401 in the first direction Y, the first clamping members 11 and the second clamping members 12 in the first clamping assembly 10 stop moving. At this time, the first clamping members 11 and the second clamping members 12 in the second clamping assembly 10 can still be pushed by the first elastic members 31 and the second elastic members 32 until the first clamping members 11 and the second clamping members 12 in the second clamping assembly 10 abut against the smaller second pin 402 in the first direction Y, and the first clamping members 11 and the second clamping members 12 in the second clamping assembly 10 stop moving.

[0069] The beneficial effects of this application embodiment are as follows: The first elastic element 31 and the second elastic element 32 facilitate control of the elastic force on the first clamping member 11 and the second clamping member 12, thus facilitating control of the clamping force of the clamping assembly 10. Since the two first elastic elements 31 and the two second elastic elements 32 can respectively push the first clamping member 11 and the second clamping member 12 to move independently, in the first direction Y, the two first clamping members 11 can move to different positions according to the pin size and abut against the first pin 401 or the second pin 402, and the two second clamping members 12 can move to different positions according to the pin size and abut against the first pin 401 or the second pin 402, enabling the first clamping member 11 and the second clamping member 12 to stably abut against both sides of the first pin 401 or the second pin 402, thus stably clamping the first pin 401 and the second pin 402.

[0070] In some embodiments, please refer to Figures 2 to 3 The correction mechanism 100 also includes a guide structure 60 connected to the clamping assembly 10, the guide structure 60 being used to guide the clamping assembly 10 to move along the deformation direction of the elastic assembly 30.

[0071] The guide structure 60 is slidably connected to the first clamping member 11 and the second clamping member 12 to guide the first clamping member 11 and the second clamping member 12 to slide along their length direction. The length direction of the guide structure 60 is set at an angle to the second direction X. Optionally, the length direction of the guide structure 60 is the first direction Y.

[0072] The guide structure 60 can also guide the elastic component 30 to deform along the length direction of the guide structure 60.

[0073] Optionally, the guide structure 60 includes a plurality of guide rods extending along a first direction Y. The guide rods are slidably connected to the drive assembly 20 and fixedly connected to the first clamping member 11 or the second clamping member 12. The guide structure 60 may also be a structure such as a guide groove. Optionally, the elastic component 30 includes a spring sleeved on the guide rod, allowing the spring to deform along the length direction of the guide rod.

[0074] The beneficial effects of this application embodiment are as follows: the guide structure 60 can guide the clamping component 10 to move along its length direction, so that the clamping component 10 moves stably. The guide structure 60 can also guide the elastic component 30 to deform along the length direction of the guide structure 60, so that the elastic force of the elastic component 30 is consistent with the moving direction of the clamping component 10, so that the elastic component 30 stably pushes the clamping component 10 to move.

[0075] In some embodiments, please refer to Figures 2 to 3 The first clamping member 11 and the second clamping member 12 are both made of metal. The correction mechanism 100 also includes an insulating member 70 disposed between each clamping component 10 to separate each clamping component 10.

[0076] Optionally, the first clamping member 11 and the second clamping member 12 may be made of stainless steel, brass or aluminum alloy, etc.

[0077] Optionally, the insulating element 70 may comprise an insulating material such as polyoxymethylene or ceramic to insulate the two clamping assemblies 10 from each other. The insulating element 70 is capable of supporting the body 403 of the capacitor 400.

[0078] The beneficial effects of this application embodiment are as follows: the first clamping member 11 and the second clamping member 12 are made of metal materials with high strength and hardness and long service life. The insulating member 70 is set to separate the two clamping components 10, which can reduce the risk of the two clamping components 10 conducting the first pin 401 and the second pin 402, so that the capacitor 400 remains stable.

[0079] In some embodiments, please refer to Figure 2 and Figure 3The correction mechanism 100 also includes a base 50 and a rotating assembly 40; the driving assembly 20 and the clamping assembly 10 are both disposed on the base 50; the rotating assembly 40 is connected to the base 50 and is used to drive the base 50 to rotate along the first axis 90, the first axis 90 being perpendicular to the first direction Y and the second direction X.

[0080] The base 50 is used to support the drive assembly 20 and the clamping assembly 10.

[0081] The rotating assembly 40 can drive the base 50 to rotate, thereby driving the drive assembly 20 and the clamping assembly 10 on the base 50 to rotate. Optionally, the rotating assembly 40 may include an angle adjuster, a bolt, or a stepper motor, etc.

[0082] For ease of description, a third direction V is defined perpendicular to the first axis 90. This third direction V forms an angle with the second direction X, and is fixed. Initially, with the third direction V as a reference, the first direction Y is parallel to the third direction V, and the clamping space 13 has its smallest size on the third direction V. As the rotating component 40 drives the clamping component 10 to rotate, the first direction Y changes, forming an angle with the third direction V. At this point, the size of the clamping space 13 on the third direction V increases to accommodate the larger first pin 401 and second pin 402 on the third direction V. When the rotating component 40 drives the clamping component 10 to rotate, the size of the clamping space 13 on the third direction V changes.

[0083] The beneficial effects of this application embodiment are as follows: For the first pin 401 and the second pin 402, which have a larger size in the third direction V, the rotation component 40 can drive the clamping component 10 to rotate, which can increase the size of the clamping space 13 in the third direction V, making it easier for the first pin 401 and the second pin 402 to be placed into the clamping space 13; by using the rotation component 40 to drive the clamping component 10 to rotate at different angles, the size of the clamping space 13 in the third direction V can be changed, which can be applied to the first pin 401 and the second pin 402 of different sizes.

[0084] In some embodiments, please refer to Figures 2 to 3 The calibration mechanism 100 also includes a support component 80, which supports the body 403 of the capacitor 400.

[0085] The support component 80 can be set at the same height as the clamping component 10, and together with the clamping component 10, it can support the body 403 of the capacitor 400; or, the support component 80 can be at least partially higher than the clamping component 10, with a height difference of h, and the support component 80 can support the body 403 of the capacitor 400 independently, separating the body 403 of the capacitor 400 from the clamping component 10 in the height direction.

[0086] When the calibration mechanism 100 includes an insulating member 70, the insulating member 70 cooperates with the support assembly 80 to support the main body 403 of the capacitor 400, and the insulating member 70 can be used as part of the support assembly 80.

[0087] The beneficial effects of this embodiment are as follows: The support component 80 supports the main body 403 of the capacitor 400. The support component 80 and the clamping component 10 jointly support the main body 403 of the capacitor 400, increasing the contact area between the calibration mechanism 100 and the main body 403 of the capacitor 400, thus making the capacitor 400 more stable on the calibration mechanism 100. The support component 80 separates the main body 403 of the capacitor 400 from the clamping component 10, reducing the impact of the movement of the clamping component 10 on the capacitor 400, further stabilizing the capacitor 400 on the calibration mechanism 100.

[0088] In some embodiments, please refer to Figure 2 The support assembly 80 includes at least two support members 81, each of which is disposed on both sides of the clamping assembly 10 along the second direction X. The support member 81 is an insulating structural member.

[0089] Two support members 81 are respectively disposed on both sides of the integral assembly formed by each clamping component 10 along the second direction X. The two support members 81 can be disposed separately or disposed as an integral structure.

[0090] The support member 81 comprises an insulating material such as polyoxymethylene or ceramic. Optionally, a connecting plate is connected to the bottom end of the support member 81 and the insulator 70. The support member 81, the insulator 70, and the connecting plate are integrally formed, and the top ends of the support member 81 and the insulator 70 are at the same height, jointly supporting the main body 403 of the capacitor 400. Optionally, each support member 81, the insulator 70, and the connecting plate form a groove, and the clamping assembly 10 is slidably disposed within the groove.

[0091] The beneficial effects of this application embodiment are as follows: the two support members 81 can support the main body 403 of the capacitor 400 at two positions along the edge of the capacitor 400 in the second direction X, making the capacitor 400 more stable; the support members 81 are made of insulating material, which can reduce the risk that the support members 81 will conduct the first pin 401 and the second pin 402 through the clamping assembly 10.

[0092] In some embodiments, please refer to Figures 2 to 3 The first clamping member 11 and / or the second clamping member 12 are provided with a receiving space 14 on the side away from the clamping space 13 along the first direction Y. The receiving space 14 is used to receive one or more of the other pins of the capacitor 400, excluding the first pin 401 and the second pin 402.

[0093] The first clamping member 11 has a receiving space 14 on the side away from the clamping space 13 along the first direction Y; or, the second clamping member 12 has a receiving space 14 on the side away from the clamping space 13 along the first direction Y; or, both the first clamping member 11 and the second clamping member 12 have a receiving space 14 on the side away from the clamping space 13 along the first direction Y. The receiving space 14 can be a groove or a notch, etc.

[0094] Please refer to Figure 7 Other pins refer to the pins on capacitor 400 that do not require calibration and are not located in the arrangement direction of the first pin 401 and the second pin 402. Optionally, other pins are pins used to support and fix capacitor 400 and are not connected to the positive or negative terminal. Optionally, the dimensions of the first clamping member 11 and the second clamping member 12 in the second direction X are both smaller than the distance between the first pin 401 and the adjacent other pins and smaller than the distance between the second pin 402 and the adjacent other pins, so that when the first pin 401 and the second pin 402 are located in the clamping space 13, the other pins are located on the side of the first clamping member 11 or the second clamping member 12 away from the clamping space 13 and are located in the receiving space 14. Optionally, the dimensions of the first clamping member 11 and the second clamping member 12 in the second direction X are less than 10 mm.

[0095] Optionally, when the capacitor 400 has more than two pins, the clamping space 13 can only accommodate the first pin 401 and the second pin 402, and cannot accommodate other pins that are not in the same arrangement direction as the first pin 401 and the second pin 402.

[0096] The beneficial effects of this application embodiment are: the accommodating space 14 is able to accommodate other pins besides the first pin 401 and the second pin 402, reducing the risk of other pins being placed on the clamping assembly 10 and reducing the possibility of the capacitor 400 falling off the clamping assembly 10.

[0097] In some embodiments, please refer to Figures 2 to 5 The correction mechanism 100 includes a drive assembly 20, two clamping assemblies 10, an elastic assembly 30, a guide structure 60, a support assembly 80, and a rotation assembly 40.

[0098] The clamping assembly 10 includes a first clamping member 11 and a second clamping member 12 disposed opposite to each other along a first direction Y. A clamping space 13 is provided between the first clamping member 11 and the second clamping member 12, which is used to accommodate the first pin 401 and the second pin 402 of the capacitor 400. Accommodating spaces 14 are provided on the side of the first clamping member 11 and the second clamping member 12 away from the clamping space 13 along the first direction Y. The two clamping assemblies 10 are respectively used to clamp the first pin 401 and the second pin 402. The two clamping assemblies 10 are distributed along a second direction X, so that the first pin 401 and the second pin 402 are arranged along the second direction X, which is perpendicular to the first direction Y. A driving assembly 20 is used to drive the first clamping member 11 and the second clamping member 12 to move closer or further apart via an elastic component 30. The driving assembly 20 is a gripper cylinder.

[0099] The guide structure 60 is used to guide the clamping assembly 10 to move along the first direction Y. The guide structure 60 includes a plurality of guide rods extending along the first direction Y. The guide rods are slidably connected to the drive assembly 20 and fixedly connected to the first clamping member 11 or the second clamping member 12.

[0100] The elastic component 30 abuts against both the drive component 20 and the clamping component 10, so that the drive component 20 drives the clamping component 10 to move via the elastic component 30. The elastic component 30 includes two first elastic elements 31 and two second elastic elements 32. The first elastic elements 31 are fixedly connected to one jaw of the gripper cylinder and the first clamping member 11, respectively. The second elastic elements 32 are fixedly connected to the other jaw of the gripper cylinder and the second clamping member 12, respectively. Both the first elastic elements 31 and the two second elastic elements 32 are springs sleeved on the guide rod, allowing the springs to deform along the length of the guide rod.

[0101] An insulating member 70 is disposed between two clamping assemblies 10 to separate the two clamping assemblies 10. A support assembly 80 is used to support the body 403 of the capacitor 400. The top of the support assembly 80 is higher than the clamping assembly 10, and the height difference between the two is h. The support assembly 80 can support the body 403 of the capacitor 400 independently, separating the body 403 of the capacitor 400 from the clamping assembly 10 in the height direction. The support assembly 80 includes at least two support members 81, which are respectively disposed on both sides of the clamping assembly 10 along the second direction X. A connecting plate is connected to the bottom end of the support member 81 and the insulating member 70. The support member 81, the insulating member 70 and the connecting plate are integrally formed. The tops of the support member 81 and the insulating member 70 are at the same height and jointly support the body 403 of the capacitor 400.

[0102] The correction mechanism 100 also includes a base 50 and a rotating assembly 40; the driving assembly 20, the clamping assembly 10, the insulating component 70 and the supporting assembly 80 are all disposed on the base 50; the rotating assembly 40 is connected to the base 50 and is used to drive the base 50 to rotate along the first axis 90, the first axis 90 being perpendicular to the first direction Y and the second direction X.

[0103] Secondly, embodiments of this application also provide a calibration device, please refer to... Figure 1 , Figure 2 and Figure 4 The calibration device 1000 includes a first calibration mechanism 200, a second calibration mechanism, and a conveying mechanism 300. The first calibration mechanism 200 includes a fixture and a rotator. The fixture is used to fix the capacitor 400, and the rotator is connected to the fixture and is used to drive the fixture and the capacitor 400 to rotate, thereby calibrating the position of the capacitor 400. The conveying mechanism 300 is used to convey the capacitor 400 from the first calibration mechanism 200 to the second calibration mechanism. The second calibration mechanism is used to calibrate the capacitor 400 after calibration by the first calibration mechanism 200. Any calibration mechanism 100 in any of the first aspect embodiments can serve as the second calibration mechanism.

[0104] Optionally, the first calibration mechanism 200 also includes an identification camera for identifying the positions of the first pin 401 and the second pin 402.

[0105] Optionally, the retainer may include a gripper cylinder, etc.

[0106] The rotator can drive capacitor 400 to rotate around a center line, correcting the position of the first pin 401 and the second pin 402 relative to the center line of capacitor 400. Optionally, the rotator can drive capacitor 400 to rotate at different angles based on the recognition result from the recognition camera. Optionally, the rotator may include a stepper motor or a screw, etc.

[0107] The conveying mechanism 300 can convey the capacitor 400 to a specific position on the clamping assembly 10. Optionally, the conveying mechanism 300 includes a clamping cylinder and a tilting cylinder. The clamping cylinder includes two opposing V-shaped grippers that can guide the capacitor 400 to a specific position. The tilting cylinder is connected to the clamping cylinder and is used to rotate the clamping cylinder and the capacitor 400 by 180°, which can align the axis of the capacitor 400 with the center line of the whole formed by the two clamping assemblies 10 (the center line is perpendicular to the first direction Y and the second direction X) to place the capacitor 400.

[0108] Optionally, in this embodiment of the application, the process of correcting the capacitor 400 is as follows: the camera identifies the position of the first pin 401 and the second pin 402, then the fixer fixes the capacitor 400, and the rotator drives the fixer and the capacitor 400 to rotate around the center line, so that the first pin 401 and the second pin 402 rotate to the preset position.

[0109] The clamping cylinder then clamps the capacitor 400 and guides it to a specific position. The flipping cylinder rotates the clamping cylinder and the capacitor 180° so that the leads of the capacitor 400 face down. The capacitor 400 is then placed on the second calibration mechanism, and its center line is aligned with the center of the whole composed of the two clamping components 10.

[0110] When the capacitor 400 is placed on the second calibration mechanism, the positions of the first pin 401 and the second pin 402 relative to the center line of the capacitor 400 are uncertain. If the first pin 401 or the second pin 402 is placed on the first clamping member 11 or the second clamping member 12, the body 403 of the capacitor 400 cannot be stably placed on the second calibration mechanism, and the capacitor 400 will fall off the second calibration mechanism. If the first pin 401 and the second pin 402 are placed in the clamping space 13, the body 403 of the capacitor 400 can be kept stable on the clamping assembly 10, and the second calibration mechanism can push the first pin 401 and the second pin 402 to calibrate the capacitor 400.

[0111] The beneficial effects of this application embodiment are as follows: the second calibration mechanism in the calibration device 1000 uses the calibration mechanism 100 of the first aspect embodiment, which can place the first pin 401 and the second pin 402 with a large deviation from the preset position on the clamping component 10, so that the capacitor 400 falls off the clamping component 10. This can avoid placing the capacitor 400 with a large positional deviation of the first pin 401 and the second pin 402 into the test socket, and can reduce the risk of the first pin 401 and the second pin 402 of the capacitor 400 colliding with the capacitor test socket 500. The second calibration mechanism can also push the first pin 401 and the second pin 402 in the clamping space 13 so that the first pin 401 and the second pin 402 can be arranged along the second direction X, so that the first pin 401 and the second pin 402 can be placed in the corresponding clamping gap 501 on the capacitor test holder 500, reducing the risk of the first pin 401 and the second pin 402 of the capacitor 400 damaging the capacitor test holder 500. It can solve the technical problem that the pins of the horn capacitor collide with the capacitor test holder 500, which can easily lead to damage to the capacitor test holder 500 and the horn capacitor.

[0112] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
