Description

Technical Field

[0001] This application relates to the field of semiconductor testing technology, and in particular to a docking device and testing equipment. Background Technology

[0002] During chip testing, the docking device supports and elevates the probes, allowing them to contact the conductive parts of the circuit board, thereby connecting the circuit and signal channels for testing. Because the probes' contact ends are equipped with spring structures, and to improve efficiency, the support plate typically needs to support multiple probes simultaneously. Therefore, significant elastic forces must be overcome during the contact phase between the probes and the PCB connectors.

[0003] In related technologies, a cylinder is used to directly push the support plate of the probe vertically upwards, causing the probe to move upwards and make contact with the PCB connector. This vertical cylinder configuration not only occupies a large amount of space in the vertical direction, but also provides no mechanical gain in the cylinder's output thrust. To improve the stability of the electrical connection between the probe and the PCB connector, the cylinder power or the number of cylinders needs to be increased, which will significantly increase the space occupied by the docking device and is detrimental to the miniaturization design of the testing equipment.

The movement trajectory of the second guide portion relative to the rotating component is a second trajectory segment perpendicular to the first direction. The extension of the second trajectory segment intersects the first axis. The driving assembly drives the rotating component to rotate, thereby causing the second guide portion to move along the first trajectory segment.

One end of the linkage rod is provided with a first slide groove extending along the axial direction of the linkage rod, and the other end of the linkage rod is provided with a second slide groove extending along the axial direction of the linkage rod. The second guide portion is slidably disposed in the first slide groove, and the fourth guide portion is slidably disposed in the second slide groove.

[0013] In one or more of the above optional embodiments, the mounting plate is provided with a third strip-shaped hole extending along the second direction, and the fourth guide portion passes through the third strip-shaped hole and is slidably disposed in the second groove.

[0014] In one or more of the above optional embodiments, the number of driving mechanisms, the number of second guide portions, the number of fourth guide portions, the number of first strip holes, and the number of third strip holes are all two.

[0016] In one or more of the above optional embodiments, a guide rod extending along a first direction is included.

[0019] According to a second aspect of this application, a testing device is provided, including the docking device described above.

[0020] The beneficial effects of the embodiments of this application are as follows: Compared with the method in related technologies that uses a vertically arranged drive cylinder to directly push the support plate, the docking device provided in this application uses a rotating member as a lever to drive the second guide part and the first pusher part to move. The first pusher part then pushes the first guide part, causing the support plate to move along the first direction. The rotating member, acting as a lever, provides mechanical gain. Furthermore, when the support plate moves along the first direction, the second guide part moves closer to the first axis along the second trajectory segment, thereby reducing the resistance arm and further enhancing the mechanical gain effect. While ensuring the stability of the probe's contact with the circuit board, it allows for the use of smaller, lower-power drive components, which helps reduce the overall size of the docking device. By changing the direction of the driving force of the drive component through the rotating member, the drive component can be arranged in a direction perpendicular to the first direction, which helps reduce the space occupied by the docking device in the first direction.

[0033] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0034] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0035] Please see Figures 1-3 In some embodiments, the docking device 100 includes a mounting base 1, a support plate 2, a first pushing member 3, a first guide portion 51, a second guide portion 52, and a driving mechanism 4. The support plate 2 is movably disposed on the mounting base 1 along a first direction X, and the first pushing member 3 is movably disposed on the mounting base 1 along a second direction Y. The first guide portion 51 is disposed on the support plate 2 and is slidably connected to the first pushing member 3. The first pushing member 3 is used to push the first guide portion 51, thereby driving the support plate 2 to move along the first direction X. The second guide portion 52 is disposed on the first pushing member 3. The drive mechanism 4 includes a rotating member 41 and a drive assembly 42 connected to each other. The rotating member 41 is rotatably mounted on the mounting base 1 about a first axis Z1, which is parallel to the first direction X. The second guide part 52 moves relative to the mounting base 1 with the first push member 3 along a first trajectory segment G1, along a third direction Z. The first axis Z1 is located on one side of the first trajectory segment G1. The second guide part 52 is movably mounted on the rotating member 41. The second guide part 52 moves relative to the rotating member 41 along a second trajectory segment G2, which is perpendicular to the first direction X. The extension of the second trajectory segment G2 intersects the first axis Z1. The drive assembly 42 drives the rotating member 41 to rotate, thereby causing the second guide part 52 to move along the first trajectory segment G1. During the movement of the support plate 2 along the first direction X, the second guide part 52 moves closer to the first axis Z1 along the second trajectory segment G2. The first direction X, the second direction Y, and the third direction Z are all mutually perpendicular.

[0036] When the drive assembly 42 drives the rotating member 41 to rotate, the rotating member 41 drives the first pushing member 3 to move in a direction parallel to the second direction Y through the second guide part 52. Then, the sliding cooperation between the first guide part 51 and the first pushing member 3 on the support plate 2 converts the movement of the first pushing member 3 in the second direction Y into a change in the height of the support plate 2 in the first direction X. When the first pushing member 3 moves, the second guide part 52 moves relative to the mounting base 1 on the first trajectory line segment G1, and the second guide part 52 moves relative to the rotating member 41 along the second trajectory line segment G2, causing a change in the distance between the second guide part 52 and the first axis Z1. When the second guide part 52 is close to the first axis Z1, the resistance arm corresponding to the driving force of the drive assembly 42 acting on the rotating member 41 is smaller, and the same driving force can balance a larger resistance; when the second guide part 52 is away from the first axis Z1, the resistance arm corresponding to the driving force of the drive assembly 42 acting on the rotating member 41 is larger, and the same driving force can balance a smaller resistance.

[0037] Please see Figures 1-6 When the docking device 100 is applied to the docking probe 200 and the circuit board 300, taking the second guide portion 52 moving along the second direction Y and the corresponding support plate 2 moving along the first direction X as an example, the support plate 2 is used to support the probe 200, and the pin of the probe 200 is set facing the first direction X. The support plate 2 moves along the first direction X to drive the pin of the probe 200 to approach and insert into the circuit board 300. In the initial stage, the probe 200 is not in contact with the circuit board 300, and the second guide portion 52 is located at the tail end G22 of the second trajectory line segment G2 away from the first axis Z1, such as... Figure 5 As shown, at this time, the resistance arm corresponding to the driving force of the drive component 42 acting on the rotating component 41 is the first resistance arm L3, and L3 has a relatively large length. As the support plate 2 continues to move along the first direction X, the probe 200 gradually approaches the circuit board 300 and begins to make contact. The spring of the probe 200 is compressed, and the circuit board 300 generates a reaction force on the probe 200, increasing the required driving force. The second guide part 52 has moved along the second trajectory line segment G2 towards the direction close to the first axis Z1. After the second guide part 52 is located near the first end G21 of the second trajectory line segment G2, as shown... Figure 6 As shown, at this time, the driving force of the drive component 42 acting on the rotating component 41 corresponds to the second resistance arm L4, L4 < L3. According to the lever principle, when the resistance torque remains unchanged, the resistance arm decreases, the resistance that can be balanced increases, which helps to overcome the large elastic force when the probe 200 and the circuit board 300 come into contact.

[0038] Compared to the method in related technologies where a vertically arranged drive cylinder directly pushes the support plate 2, the docking device 100 provided in this application uses a rotating member 41 as a lever to drive the second guide portion 52 and the first pusher 3 to move. The first pusher 3 then pushes the first guide portion 51, causing the support plate 2 to move along the first direction X. The rotating member 41, acting as a lever, provides mechanical gain. When the support plate 2 moves along the first direction X, the second guide portion 52 moves closer to the first axis Z1 along the second trajectory segment G2, thereby reducing the resistance arm and further enhancing the mechanical gain effect. While ensuring the stability of the probe 200's contact with the circuit board 300, a smaller and lower-power drive component 42 can be used, which helps reduce the overall size of the docking device 100. By changing the direction of the driving force of the drive component 42 through the rotating member 41, the drive component 42 can be arranged in a direction perpendicular to the first direction X, which helps reduce the space occupied by the docking device 100 in the first direction X.

[0039] In some embodiments, the axis Z5 of the second guide portion 52 is parallel to the first axis Z1, and the axis Z5 of the second guide portion 52 intersects with the first trajectory segment G1 and the second trajectory segment G2.

[0040] In some embodiments, the drive assembly 42 includes a telescopic rod 421 and a drive portion 422. The telescopic rod 421 is telescopically disposed at one end of the drive portion 422. The end of the telescopic rod 421 away from the drive portion 422 is rotatably connected to the rotating member 41. The drive portion 422 is rotatably connected to the mounting base 1. Figure 6 As shown, when the second guide portion 52 is located at the beginning G21 of the second trajectory segment G2 near the first axis Z1, the power arm of the driving force acting on the rotating member 41 is L1. When the second guide portion 52 is located at the end G22 of the second trajectory segment G2 away from the first axis Z1, as... Figure 5 As shown, the power arm of the driving force acting on the rotating component 41 is L2, and L1 > L2. By setting the docking device 100 to L1 > L2, when the required driving force increases during the stage when the probe 200 abuts against the circuit board 300, the length of the power arm L1 is larger. According to the torque balance "power × power arm = resistance × resistance arm", the larger power arm can provide a larger driving torque while keeping the power of the driving component 42 constant. Furthermore, since the corresponding second resistance arm L4 is smaller at this time, the resistance that can be balanced is significantly increased through their cooperation. This can overcome the larger reaction force when the probe 200 abuts against the circuit board 300, thus facilitating the stable abutment of the probe 200 against the circuit board 300.

[0041] In some embodiments, the end of the telescopic rod 421 away from the drive unit 422 is rotatably mounted on the rotating member 41 about the second axis Z2, and the end of the drive unit 422 away from the telescopic rod 421 is rotatably connected to the mounting base 1 about the third axis Z3. Both the second axis Z2 and the third axis Z3 are parallel to the first axis Z1, the axis of the telescopic rod 421 is perpendicular to the second axis Z2, and the axis Z6 of the telescopic rod 421 intersects the second axis Z2. The distance between the first axis Z1 and the axis Z6 of the telescopic rod 421 is the length of the power arm.

[0042] Please see Figures 1-3 and Figure 7 In some embodiments, the mounting base 1 includes a mounting plate 11, which is disposed opposite to the support plate 2 along a first direction X. A first pushing member 3 is disposed on one side of the support plate 2 along a third direction Z. A driving mechanism 4 is disposed on the side of the mounting plate 11 facing away from the support plate 2. The mounting plate 11 is provided with a first strip hole 111. A second guide portion 52 passes through the first strip hole 111. When the rotating member 41 rotates, the second guide portion 52 slides along the first trajectory line segment G1 in the first strip hole 111.

[0043] In some embodiments, the rotating member 41 is provided with a second strip hole 4131, and the second guide portion 52 passes through the first strip hole 111 and is inserted into the second strip hole 4131. The second guide portion 52 moves relative to the rotating member 41 within the second strip hole 4131 along the second trajectory line segment G2.

[0044] In some embodiments, the second guide portion 52 includes a first bushing 512 and a connecting shaft 511. One end of the connecting shaft 511 is connected to the first pusher 3. The first bushing 512 is sleeved on the connecting shaft 511 and can rotate relative to the connecting shaft 511. The first bushing 512 is at least partially disposed in the first strip hole 111.

[0045] In some embodiments, the second guide portion 52 includes a second bushing 513, which is sleeved on the connecting shaft 511. The first bushing 512 and the second bushing 513 are arranged sequentially along the support plate 2 toward the mounting plate 11. The second bushing 513 is rotatable relative to the connecting shaft 511. The second bushing 513 is at least partially disposed in the second strip hole 4131. The second bushing 513 allows the rotating member 41 to rotate relative to the second guide portion 52.

[0046] In some embodiments, the rotating member 41 includes a first arm 411, a rotating part 412, and a second arm 413. The rotating part 412 is rotatably mounted on the mounting plate 11 about a first axis Z1. One end of the first arm 411 is connected to the rotating part 412, and the other end of the first arm 411 is rotatably connected to the end of the telescopic rod 421 away from the drive part 422 about a second axis Z2. One end of the second arm 413 is connected to the rotating part 412. The second arm 413 extends in a direction parallel to the second trajectory line segment G2, and a second strip hole 4131 is provided in the second arm 413.

[0047] In some embodiments, the drive assembly 42 is a cylinder. It is understood that the drive assembly 42 is not limited to a cylinder; for example, in some other embodiments, the drive assembly 42 may also be an electric actuator.

[0048] Please see Figure 1 and Figure 4 In some embodiments, the docking device 100 includes a guide rod 6 extending along a first direction X. The guide rod 6 is disposed on the mounting plate 11 and passes through the support plate 2 along the first direction X. The support plate 2 is capable of reciprocating relative to the guide rod 6 in a direction parallel to the first direction X.

[0049] In some embodiments, there are two guide rods 6, which are arranged opposite each other along the second direction Y, and the two guide rods 6 are respectively inserted through the two opposite ends of the support plate 2 along the second direction Y.

[0050] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8In some embodiments, the docking device 100 includes a second pushing member 8 connected to the driving mechanism 4. The second pushing member 8 is movably disposed on the mounting plate 11 along the second direction Y and on the side of the support plate 2 opposite to the first pushing member 3 along the third direction Z. The docking device 100 includes a third guide portion 53 disposed on the support plate 2 and slidably connected to the second pushing member 8. The third guide portion 53 can slide relative to the second pushing member 8 to drive the support plate 2 to move relative to the mounting plate 11 along the first direction X. By providing the first pushing member 3 and the second pushing member 8 on both sides of the support plate 2, it is beneficial to improve the stability of the support plate 2 during movement in the first direction X.

[0051] In some embodiments, the drive mechanism 4 includes a linkage rod 7, which is rotatably disposed on the side of the mounting plate 11 facing away from the support plate 2 about a fourth axis Z4. The docking device 100 includes a fourth guide portion 54, which is disposed on the second pusher 8. The movement trajectory of the fourth guide portion 54 relative to the mounting base 1 when it moves with the second pusher 8 is a third trajectory line segment (not shown in the figure), along the third direction Z. The fourth axis Z4 is located between the first trajectory line segment G1 and the third trajectory line segment. One end of the linkage rod 7 is provided with a first groove 71 extending along the axial direction of the linkage rod 7, and the other end of the linkage rod 7 is provided with a second groove 72 extending along the axial direction of the linkage rod 7. The second guide portion 52 is slidably disposed in the first groove 71 along the extension direction of the first groove 71, and the fourth guide portion 54 is slidably disposed in the second groove 72 along the extension direction of the second groove 72. The linkage rod 7 is used to make the first pusher 3 and the second pusher 8 move synchronously in opposite directions. The rotation of the rotating member 41 drives the second guide part 52 to move along the second direction Y. The second guide part 52 pushes the linkage rod 7 to rotate by abutting against the inner wall of the first slide groove 71. The linkage rod 7 rotates around the fourth axis Z4, and then pushes the fourth guide part 54 to move in the opposite direction to the second direction Y through the inner wall of the second slide groove 72. This causes the first pusher 3 and the second pusher 8 to apply a pushing force to the support plate 2 through the first guide part 51 and the third guide part 53, respectively, and push the support plate 2 to move along the first direction X.

[0052] In some embodiments, the first slide groove 71 passes through the linkage rod 7 along the first direction X. Along the first direction X, the first slide groove 71 is located between the first strip hole 111 and the second strip hole 4131, and the second guide portion 52 passes through the first slide groove 71.

[0053] In some embodiments, along the first direction X, the two opposite ends of the first bushing 512 are respectively disposed in the first strip hole 111 and the first groove 71.

[0054] In some embodiments, the mounting plate 11 is provided with a third strip-shaped hole 112 extending along the second direction Y, and the fourth guide portion 54 passes through the third strip-shaped hole 112 and is inserted into the second slide groove 72. The fourth guide portion 54 slides within the third strip-shaped hole 112 along a third trajectory line segment.

[0055] Please see Figure 8 and Figure 9 In some embodiments, the number of driving mechanisms 4, the number of second guide portions 52, the number of fourth guide portions 54, the number of first strip holes 111, and the number of third strip holes 112 are all two. The first pushing member 3 includes a first end 3a and a second end 3b arranged sequentially along the second direction Y. The second pushing member 8 includes a third end 8a and a fourth end 8b arranged sequentially along the second direction Y. One second guide portion 52 is disposed at the second end 3b, another second guide portion 52 is disposed at the third end 8a, one fourth guide portion 54 is disposed at the first end 3a, and another fourth guide portion 54 is disposed at the fourth end 8b. Along the second direction Y, the two driving mechanisms 4 are arranged opposite to each other. One second guide portion 52 is movably disposed on a rotating member 41 along a second trajectory segment G2, and the rotating member 41 is rotatably connected to the second guide portion 52. One second guide portion 52 is slidably disposed on a first strip hole 111, and one fourth guide portion 54 is slidably disposed on a third strip hole 112. When one drive mechanism 4 drives the second guide portion 52 located at the second end 3b to move along the second direction Y, another drive mechanism 4 drives the second guide portion 52 located at the third end 8a to move in the opposite direction to the second direction Y. By having the two drive mechanisms 4 work together to push the first pusher 3 and the second pusher 8 to move, it is beneficial to increase the driving force acting on the support plate 2 and improve the load capacity of the docking device 100.

[0056] It is worth noting that the linkage 7 can be configured to correspond to either of the two drive mechanisms 4. For example... Figure 9 As shown, the second guide portion 52, located at the second end 3b, is slidably disposed in the first slide groove 71, and the fourth guide portion 54, located at the fourth end 8b, is slidably disposed in the second slide groove 72. By providing the linkage rod 7, it is beneficial to improve the synchronization of the movements of the first pushing member 3 and the second pushing member 8 during movement.

[0057] It is also worth noting that the first pusher 3 is slidably disposed in a first strip hole 111 via a second guide portion 52 disposed at the second end 3b, and slidably disposed in a third strip hole 112 via a fourth guide portion 54 disposed at the first end 3a, so that the first pusher 3 can move relative to the mounting plate 11 in the second direction Y; the second pusher 8 is slidably disposed in another first strip hole 111 via a second guide portion 52 disposed at the third end 8a, and slidably disposed in another third strip hole 112 via a fourth guide portion 54 disposed at the fourth end 8b, so that the second pusher 8 can move relative to the mounting plate 11 in the second direction Y.

[0058] It is understood that the first pusher 3 and the second pusher 8 are not limited to being movably connected to the mounting base 1 through the guide portion and the strip hole. The first pusher 3 and the second pusher 8 can also be movably connected to the mounting base 1 through the cooperation of the slider and the slide rail.

[0059] Please see Figure 1 , Figure 2 , Figure 8 and Figure 10 In some embodiments, the first pushing member 3 is provided with a first guide groove 31, and the first guide groove 31 is provided with a first inclined surface 311 facing the first direction X. The first inclined surface 311 includes a first starting end 3111 and a first ending end 3112 arranged sequentially in a direction opposite to the second direction Y. The first ending end 3112 is inclined towards the first direction X relative to the first starting end 3111. By providing the first inclined surface 311, when the first pushing member 3 moves along the second direction Y, the first inclined surface 311 supports and guides the first guiding part 51 to slide relative to the first inclined surface 311 from the first starting end 3111 to the first ending end 3112, thereby converting the movement of the first pushing member 3 along the second direction Y into the movement of the support plate 2 along the first direction X.

[0060] In some embodiments, the first guide groove 31 is provided with a second inclined surface 312 facing the first direction X. The second inclined surface 312 includes a second starting end 3121 and a second ending end 3122 arranged sequentially in the direction opposite to the second direction Y. The second ending end 3122 is inclined towards the first direction X relative to the second starting end 3121. The second inclined surface 312 and the first inclined surface 311 are arranged sequentially in the second direction Y. The inclination angle of the first inclined surface 311 is greater than the inclination angle of the second inclined surface 312. When the first guide portion 51 slides along the first inclined surface 311, corresponding to the stage before the probe 200 contacts the circuit board 300, the first inclined surface 311 has a large inclination angle, and the support plate 2 moves faster along the first direction X, so as to quickly approach the circuit board 300; when the first guide portion 51 slides to the second inclined surface 312, the inclination angle of the second inclined surface 312 is small, the moving speed of the support plate 2 along the first direction X slows down, and at this time the force required for the first pusher 3 to push the first guide portion 51 to slide along the second inclined surface 312 is smaller, so that the drive mechanism 4 can overcome the larger elastic force when the probe 200 abuts against the circuit board 300, and improve the reliability of the abutment between the probe 200 and the circuit board 300.

[0061] In some embodiments, the number of first guide grooves 31 is at least two, and the at least two first guide grooves 31 are arranged sequentially along the second direction Y. The number of first guide portions 51 is the same as the number of first guide grooves 31 and corresponds one-to-one. A first guide portion 51 is slidably disposed on a first guide groove 31.

[0062] In some embodiments, the first guide portion 51 is a follower cam rotatably disposed on the support plate 2. The outer peripheral surface of the follower cam makes rolling contact with the first inclined surface 311 and the second inclined surface 312, thereby converting sliding friction into rolling friction, which helps to reduce the frictional resistance between the first guide portion 51 and the first guide groove 31.

[0063] In some embodiments, the second pusher 8 is provided with a second guide groove 81, and a third guide portion 53 is slidably disposed in the second guide groove 81. The second guide groove 81 can coincide with the first guide groove 31 after rotating 180 degrees around a reference axis. The reference axis is parallel to the first direction X and along the third direction Z, and is located between the first pusher 3 and the second pusher 8. When the first pusher 3 moves along the second direction Y, the corresponding second pusher 8 moves synchronously in the opposite direction to the second direction Y. Since the first guide groove 31 and the second guide groove 81 have the same structure and are arranged in opposite directions, the third guide portion 53 in the second guide groove 81 can move synchronously with the first guide portion 51 in the first guide groove 31 along the first direction X, thereby jointly pushing the support plate 2 to move along the first direction X.

[0064] In some embodiments, the third guide portion 53 is a follower cam rotatably disposed on the support plate 2. The outer peripheral surface of the follower cam makes rolling contact with the second guide groove 81, converting sliding friction into rolling friction, which helps to reduce the frictional resistance between the third guide portion 53 and the second guide groove 81.
