Description

Technical Field

[0001] This invention relates to the field of industrial testing, and specifically to a probe protection structure with quick-change function. Background Technology

[0002] In various industrial testing, measurement, and experimental equipment, probes are crucial components, and they often need to be frequently replaced to meet different testing requirements. However, traditional probe protection devices are typically simple in design but complex in operation, and lack the ability to quickly replace probes, resulting in low work efficiency. Furthermore, frequent replacement operations can easily damage probes and shorten their lifespan.

[0003] Chinese patent CN216247814U discloses a probe protection device, which includes an ultrasonic probe body, a protective shell, and a top cover. Two sets of fixing plates are fixedly connected to the outer wall of the protective shell. Movable grooves are formed inside the fixing plates, and springs are fixedly connected to the inner walls of the movable grooves, with springs in a stretched state. A movable block is fixedly connected to one end of spring b11, and a clamping plate is fixedly connected to the bottom of the movable block. By clamping the clamping plate onto the probe base, the entire protection device is clamped and fixed to the probe. In use, the top cover is unscrewed to expose the probe. The main problems are: 1. The overall device is inconvenient to use, requiring manual pulling of the handle to clamp the protection device onto the probe base to protect the probe, and the top cover must be manually unscrewed before using the probe; 2. It lacks an automatic probe replacement function; when replacing with another probe, the protection device must be removed and re-clamped onto the probe to be replaced. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a probe protection structure with quick-change function, which can not only protect the probe from damage, but also has the ability to replace the probe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention discloses a probe protection structure with quick-change function, including a frame, a mounting base, a slide rail, a slider, a probe assembly, a drive motor, a flipping assembly, a clamping hand, and a protective assembly. The frame houses the mounting base, slide rail, slider, probe assembly, and drive motor inside it. The slide rail is mounted on the mounting base. The drive motor is configured to drive the slider to slide on the slide rail. The probe assembly is mounted on the slider. As the probe assembly moves with the slider towards the end of its sliding stroke, it gradually extends completely from inside the frame. The flipping assembly is located on the outside of the frame directly above the slide rail in the vertical direction and near the end of the slider's sliding stroke. The clamping hand is mounted on the flipping assembly. The flipping assembly is configured to drive the clamping hand to flip, thereby clamping the fully extended probe assembly and removing it from the slider. The protective assembly is configured to block one end of the frame near the end of the slider's sliding stroke and gradually removes the blockage as the slider moves towards the end of its sliding stroke.

[0007] Preferably, the protective assembly includes a protective cover, a first connecting rod, a swing fork, and a toggle member. The protective cover is rotatably connected to one end of the mounting base near the end of the slider's stroke. The protective cover has a groove, and a sliding rod is slidably connected within the groove. The sliding rod is located at one end of the first connecting rod, and a rocker arm is located at the other end of the first connecting rod. The rocker arm and the swing fork are located at one end of the mounting base near the beginning of the slider's stroke. The rocker arm is connected to the swing fork via a synchronous shaft, and the toggle member abuts against the swing fork. The toggle member is located on the slider.

[0008] Preferably, the flipping assembly includes a flipping motor, a drive shaft, a first gear, a driven shaft, a second gear, an adapter flange, a fixed plate, and a slide. The flipping motor is configured to drive the drive shaft to rotate. The rotation directions of the drive shaft and the driven shaft are parallel to the sliding direction of the slider. The first gear is disposed on the drive shaft, and the second gear is disposed on the driven shaft. The first gear meshes with the second gear. The two ends of the driven shaft are respectively fixedly connected to the adapter flange, and the adapter flange is connected to the fixed plate. The two sides of the gripper are disposed between the fixed plates via the slide.

[0009] Preferably, a machine vision module is provided at one end of the frame near the end of the slider's stroke.

[0010] Preferably, the probe assembly includes a probe body and a probe mounting base. The probe mounting base is disposed on the slider and has a central hole along the axial direction. A keyway is formed on the inner wall of the probe mounting base. The probe body is inserted into the central hole and is provided with a raised key that cooperates with the keyway.

[0011] Preferably, a second connecting rod and a third connecting rod with their ends flush are arranged overlapping along the axial direction within the probe body. A connecting rod mounting shaft is arranged radially within the probe body, passing through the overlapping part of the second connecting rod and the third connecting rod. A first mounting member is provided at the end of the second connecting rod and the third connecting rod away from the probe mounting seat, and a second mounting member is provided at the end of the second connecting rod and the third connecting rod close to the probe mounting seat. The probe body is provided with a first mounting hole and a second mounting hole communicating with the inside and outside. The first mounting member and the second mounting member are slidably connected in the first mounting hole and the second mounting hole, respectively, and are partially exposed outside the probe body. A spring is provided between the first mounting members. After the probe body is inserted, the probe mounting seat is provided with a third mounting hole corresponding to the position of the second mounting hole. The exposed part of the second mounting member is slidably connected in the third mounting hole.

[0012] When the clamping hand clamps the probe assembly, it clamps the exposed portion of the first mounting member to bring the second and third connecting rods closer together, thereby causing the second mounting member to slide out of the third mounting hole.

[0013] Preferably, the frame is made of insulating material.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are: the present invention has a simple structure and is easy to operate, not only has good protection capabilities for the probe, but also has the function of quickly replacing the probe. Using the present invention can greatly improve work efficiency and extend the service life of the probe. Attached Figure Description

[0027] Example 1

[0028] like Figure 1-9As shown, this invention discloses a probe protection structure with quick-change function, including a frame 1, a mounting base 2, a slide rail 6, a slider 7, a probe assembly 8, a drive motor 3, a flipping assembly 4, a clamping hand 5, and a protective assembly 9. The frame 1 is a non-deformable square frame structure that houses the mounting base 2, slide rail 6, slider 7, probe assembly 8, and drive motor 3 inside the frame 1. The slide rail 6 is mounted on the mounting base 2. The drive motor 3 is configured to drive the slider 7 to slide on the slide rail 6. The probe assembly 8 is mounted on the slider 7. As the probe assembly 8 moves towards the end of its sliding stroke, it gradually extends completely from inside the frame 1. The flipping assembly 4 is located on the outside of the frame 1, directly above the slide rail 6 in the vertical direction, and close to the end of the sliding stroke of the slider 7. The clamping hand 5 is mounted on the flipping assembly 4. The flipping assembly 4 is configured to drive the clamping hand 5 to flip, thereby clamping the fully extended probe assembly 8 and removing it from the slider 7. The protective assembly 9 is configured to block one end of the frame 1 near the end of the sliding stroke of the slider 7, and the blockage gradually dissipates as the slider 7 moves towards the end of its sliding stroke.

[0029] The working principle and usage process of this embodiment are as follows:

[0030] Before use, the probe assembly 8 is installed on the slider 7, which is located at the starting point of its sliding path on the slide rail 6. At this time, the entire probe assembly 8 is inside the frame 1. The protective component 9 blocks the end of the frame 1 near the end of the slider 7's sliding path. The frame 1 and the protective component 9 form a protective barrier for the probe assembly 8, isolating it from the outside world. During use, the drive motor 3 is started, driving the slider 7 to slide on the slide rail 6. The slider 7 moves towards the end of its sliding path, at which point the probe assembly 8 gradually extends out of the frame 1. The protective component 9 gradually removes its obstruction of the end of the frame 1 near the end of the slider 7's sliding path, allowing the probe assembly 8 to extend out of the frame 1. When the slider 7 reaches the end of its sliding path, the probe assembly 8 is fully extended from the frame 1 to perform the detection work. After the detection work is completed, the slider 7 moves from the end of its sliding path back to the starting point, at which point the probe assembly 8 re-enters the frame 1. The protective component 9 then blocks the end of the frame 1 near the end of the slider 7's sliding path, thus protecting the probe assembly 8 from the outside when not in use. When the probe assembly 8 needs to be replaced, the probe assembly 8 extends out of the frame 1. At this time, the flipping component 4 controls the clamping hand 5 to flip from the standby position to the clamping position. After the clamping hand 5 reaches the clamping position, it clamps the probe assembly 8. The flipping component 4 then controls the clamping hand 5 to reset from the clamping position to the standby position. The clamping hand 5 removes the probe assembly 8 from the slider 7. At this time, other probe assemblies 8 that need to be used can be replaced.

[0031] Example 2

[0032] like Figure 1-9As shown, this embodiment is developed based on the above embodiment to solve the problem of probe protection. Specifically, this embodiment discloses a probe protection structure with quick-change function. The protection component 9 includes a protective cover 901, a first connecting rod 902, a swing fork 904, and a toggle member 905. The protective cover 901 is rotatably connected to one end of the mounting base 2 near the end of the travel of the slider 7. The protective cover 901 can cover the end of the frame 1 near the end of the travel of the slider 7, thereby protecting the probe component 8 when it is not working. A sliding groove 906 is provided on the protective cover 901. A sliding rod 907 is slidably connected in the sliding groove 906. The sliding rod 907 is located at one end of the first connecting rod 902. A rocker arm 903 is provided at the other end of the first connecting rod 902. The rocker arm 903 and the swing fork 904 are located at one end of the mounting base 2 near the start of the travel of the slider 7. The rocker arm 903 is connected to the swing fork 904 through a synchronous shaft 908. The toggle member 905 abuts against the swing fork 904 and is located on the slider 7.

[0033] When the probe assembly 8 is not working and the slider 7 is at the beginning of its sliding stroke, the actuating element 905 on the slider 7 abuts against the swing fork 904. At this time, the protective cover 901 completely covers the side of the frame 1 near the probe assembly 8. When the drive motor 3 starts working and drives the slider 7 to move towards the end of the slider 7's stroke, the actuating element 905 moves with the slider 7. The actuating element 905 causes the swing fork 904 to rotate around the synchronous shaft 908. Since the swing fork 904 and the rocker arm 903 are connected through the synchronous shaft 908, the rocker arm 903 rotates together. The rotation of the rocker arm 903 drives the first connecting rod 902 to move in the opposite direction of the slider 7's movement. The first connecting rod 902 drives the slide rod 907 to slide in the slide groove 906, thereby causing the protective cover 901 to rotate and protrude from the side of the frame 1 near the probe assembly 8. The probe assembly 8 extends from this side. When the probe assembly 8 completes its working reset, the slider 7 moves to the starting point of its stroke, causing the actuating element 905 to re-abut against the swing fork 904. The actuating element 905 causes the swing fork 904 to rotate in the opposite direction around the synchronous shaft 908, and the rocker arm 903 rotates in the opposite direction as well. The rotation of the rocker arm 903 causes the first connecting rod 902 to move in the opposite direction of the slider 7. The first connecting rod 902 causes the slide rod 907 to slide in the slide groove 906, thereby causing the protective cover 901 to rotate and cover the side of the frame 1 closest to the probe assembly 8 again.

[0034] Example 3

[0035] like Figure 1-9As shown, this embodiment is developed based on the above embodiment to solve the problem of how the flipping component 4 flips. Specifically, the flipping component 4 includes a flipping motor 401, a drive shaft 402, a first gear 403, a driven shaft 404, a second gear 405, a connecting flange 406, a fixed plate 407, and a slide table 408. The flipping motor 401 is configured to drive the drive shaft 402 to rotate. The rotation directions of the drive shaft 402 and the driven shaft 404 are parallel to the sliding direction of the slider 7. The first gear 403 is disposed on the drive shaft 402, and the second gear 405 is disposed on the driven shaft 404. The first gear 403 meshes with the second gear 405. The two ends of the driven shaft 404 are respectively fixedly connected to the connecting flange 406. The connecting flange 406 is connected to the fixed plate 407. The two sides of the gripper 5 are disposed between the fixed plate 407 via the slide table 408.

[0036] When the flipping assembly 4 is not working, the gripper 5 is in the standby position. At this time, the fixing plate 407 is set parallel to the long side of the frame 1 and the end away from the adapter flange 406 faces the starting point of the sliding stroke of the slider 7. When the slider 7 moves to the end of the sliding stroke, the probe assembly 8 is fully exposed. When the probe assembly 8 needs to be replaced, the flipping motor 401 is started. The flipping motor 401 drives the drive shaft 402 to rotate. The rotation is transmitted to the driven shaft 404 through the meshing first gear 403 and second gear 405. The rotation of the driven shaft 404 drives the fixing plate 407 to rotate, thereby driving the gripper 5 to rotate. When the fixing plate When 407 rotates to the end of its sliding stroke parallel to the long side of the frame 1 and away from the adapter flange 406, facing the slider 7, the gripper 5 reaches the gripping position. Then, the flip motor 401 stops working, and the slide table 408 slides parallel to the long side of the frame 1 to adjust the position of the gripper 5 so that it clamps the probe assembly 8. The gripper 5 removes the probe assembly 8 from the slider 7. At this time, the flip motor 401 rotates in the reverse direction, driving the drive shaft 402 to rotate in the reverse direction, thereby causing the gripper 5 to rotate in the reverse direction back to the standby position. The user can then replace the probe assembly 8. It should be noted that the slide table 408 and gripper 5 in this embodiment are any of the prior art. Since this part is not the focus of this invention, this embodiment does not further limit it.

[0037] Example 4

[0038] like Figure 1-9As shown, this embodiment is based on the above embodiment. Specifically, a machine vision module 10 is provided at one end of the frame 1 near the end of the slider 7's stroke. Under normal use, the machine vision module 10 mainly detects the wear of the probe assembly 8. When the probe assembly 8 needs to be replaced, it can assist in positioning the relative position of the gripper 5 and the probe assembly 8, facilitating the gripper 5 to hold the probe assembly 8. It should be understood that the method by which the machine vision module 10 in this embodiment achieves the above functions can be any of the machine vision recognition technologies in the prior art. Since this part is not the focus of this invention, this embodiment does not further limit it.

[0039] Example 5

[0040] like Figure 1-9 As shown, this embodiment is based on the above embodiment. Specifically, the probe assembly 8 includes a probe body 801 and a probe mounting base 802. The probe mounting base 802 is disposed on the slider 7 and has a central hole along the axial direction. A keyway 8012 is formed on the inner wall of the probe mounting base 802. The probe body 801 is inserted into the central hole and is provided with a raised key 8011 that cooperates with the keyway 8012. Through the cooperation of the raised key 8011 and the keyway 8012, the probe body 801 will not rotate after being inserted into the central hole of the probe mounting base 802, making the installation more secure.

[0041] Furthermore, a second connecting rod 803 and a third connecting rod 804, with their ends flush, are axially overlapped within the probe body 801. A connecting rod mounting shaft 805, passing through the overlap of the second connecting rod 803 and the third connecting rod 804, is radially disposed within the probe body 801. A first mounting member 806 is respectively provided at the end of the second connecting rod 803 and the third connecting rod 804 away from the probe mounting base 802, and a second mounting member 808 is respectively provided at the end of the second connecting rod 803 and the third connecting rod 804 near the probe mounting base 802. 01 is provided with a first mounting hole 807 and a second mounting hole 809 that connect the inside and outside. The first mounting member 806 and the second mounting member 808 are slidably connected in the first mounting hole 807 and the second mounting hole 809 respectively and are partially exposed outside the probe body 801. A spring 8010 is provided between the first mounting members 806. The probe mounting base 802 after being inserted into the probe body 801 is provided with a third mounting hole 8013 at the position corresponding to the second mounting hole 809. The exposed part of the second mounting member 808 is slidably connected in the third mounting hole 8013.

[0042] When the clamping hand 5 clamps the probe assembly 8, it clamps the exposed part of the first mounting member 806 to bring the second connecting rod 803 and the third connecting rod 804 closer to each other, thereby causing the second mounting member 808 to slide out of the third mounting hole 8013.

[0043] During probe body 801 installation, after aligning the raised key 8011 with the keyway 8012, the probe body 801 can be inserted into the center hole of the probe mounting base 802. The exposed portion of the second mounting member 808 abuts against the inner wall of the probe mounting base 802, causing the second connecting rod 803 and the third connecting rod 804 to move closer together. The spring 8010 between the first mounting members 806 is compressed. When the probe body 801 is fully inserted into the center hole of the probe mounting base 802, the second mounting hole 809 and the third mounting hole 801... When the mounting holes 8013 are aligned, the exposed portion of the second mounting member 808 loses contact with the inner wall of the probe mounting base 802. Due to the tension of the spring 8010, the second connecting rod 803 and the third connecting rod 804 move away from each other, causing the exposed portion of the second mounting member 808 to slide into the third mounting hole 8013. At this time, the axial movement of the probe body 801 is restricted by the second mounting member 808, and the rotation is restricted by the protruding key 8011, so that the probe body 801 is securely mounted on the probe mounting base 802. When changing the probe, the clamping hand 5 clamps the exposed portion of the first mounting member 806, compressing the spring 8010 and causing the second mounting members 808 to move closer together and slide out of the third mounting hole 8013, so that the probe body 801 can be removed from the probe mounting base 802.

[0044] Example 6

[0045] like Figure 1-9 As shown, this embodiment is based on the above embodiment. Specifically, the frame 1 is made of insulating material, which ensures the safety of the operator during use. It should be noted that the insulating material can be any type of insulating material in the prior art. Since this part is not the focus of this invention, this embodiment does not further limit it.

[0046] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
