Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and more particularly to a clamping device for a micro pressure sensor probe and an assembling device for a bougie. Background Art
[0002] As a precision sensor technology, micro pressure sensors are increasingly widely used in the field of medical devices. They are small in size, highly sensitive, and fast in response. They can monitor the pressure changes inside and outside the human body in real time, providing accurate data support for the formulation of medical plans, but at the same time, they have high requirements for the lossless packaging technology of micro pressure sensors. Taking the encapsulated micro pressure sensor for intracranial pressure measurement as an example, the encapsulated micro pressure sensor probe includes two parts: a probe and a catheter. The probe has a sensing window opening, and a sensor is fixed under the opening. The sensor is connected to a wire, which is set in the catheter, and the catheter is connected to the rear end of the probe.
[0003] Because it is used in delicate intracranial tissues, the size of the micro pressure sensor probe is very small, usually only φ1mm, and it is a thin-walled shell with a smooth appearance and a sensing window. The catheter connected to the probe is usually made of plastic, and is slender, hollow, and easily damaged. During the assembly process of the probe and the catheter, the probe and the catheter need to be clamped separately. Due to the small size of the probe, its shell is a thin-walled structure with a sensing window opening. During the assembly process, the size of the shell available for clamping is smaller, and the probe is easily deformed due to force during the clamping process if it is clamped too tightly. If it is clamped too loosely, it is easy to slip and dislocate during subsequent operations such as rotating glue dispensing. Due to the slender, hollow, and easily damaged characteristics of the catheter, it is also easy to deform, bend, deflect, etc. during the clamping process. The current simple clamping tools are easy to cause damage to the probe and the catheter. In addition, when the probe and the catheter are assembled in the center, the wire is pre-placed in the catheter to connect the sensor, and it is inserted into the specific position corresponding to the sensing window in the probe for glue dispensing and fixing. It is necessary to be able to fine-tune the positions of the two to achieve precise docking. Currently, there are no corresponding probe clamping tools and probe docking assembly tools for miniature pressure sensors to realize an automated production process. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that the probe and catheter of the micro pressure sensor probe are easily deformed and damaged during assembly and clamping, and to provide a clamping device for the micro pressure sensor probe to effectively prevent the probe from being damaged and deformed during clamping. A micro pressure sensor probe assembly device is also provided to achieve flexible clamping of the catheter and precise alignment of the probe and the catheter, thereby completing the automated assembly of the probe.
[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0006] A clamping device for a micro pressure sensor probe is provided, comprising a first clamp and a first tension adjustment member, wherein the first clamp comprises a first connecting portion, a first clamping portion and a second clamping portion, wherein the first clamping portion and the second clamping portion are both connected to the first connecting portion and are located on the same side of the first connecting portion, and a first deformation groove and a first positioning portion for accommodating the probe that are interconnected are provided between the first clamping portion and the second clamping portion, and flexible clamping of the probe is achieved by tightening the first deformation groove through the first tension adjustment member.
[0007] The clamping device of the micro pressure sensor probe of the present invention can change the width of the first deformation groove between the first clamping part and the second clamping part by operating the first tension adjustment piece, and the width of the first positioning part changes accordingly until the first positioning part is in contact with the outer peripheral surface of the probe, thereby realizing flexible clamping of the probe, having strong adaptability, simple operation, and no damage to the probe, and can avoid the probe from being deformed by force due to excessive clamping, and can also avoid the probe from being slipped and dislocated due to excessive loose clamping during the subsequent rotation and dispensing process.
[0008] Furthermore, the first deformation groove is located below the first positioning portion or below the first positioning portion and on one side close to the first connecting portion. Preferably, the first positioning portion below and on one side close to the first connecting portion are both connected to the first deformation groove, which can facilitate the probe's placement and take-and-place operation and better achieve flexible clamping of the probe. Preferably, the width of the first deformation groove is smaller than the width of the first positioning portion. By designing the first deformation groove and the first positioning portion with different widths, the probe can be prevented from falling into the first deformation groove when initially placed.
[0009] Further, a deformation hole connected to the first deformation groove is provided on one side of the first deformation groove close to the first connecting part. The setting of the deformation hole can improve the deformation capacity of the first clamping part and the second clamping part, and better realize the flexible clamping of the probe; and / or, the stiffness of the second clamping part is greater than the stiffness of the first clamping part, and the first clamping part and the second clamping part have different stiffnesses. One of the first clamping part and the second clamping part retains the stiffness and the other improves the deformation capacity, so that the probe has a reference to rely on during the clamping process, thereby effectively improving the positioning accuracy and facilitating the flexible clamping of the probe; and / or, the first connecting part is provided with a counterweight hole, and objects with relatively high density such as counterweight blocks and lead mud can be added to the counterweight hole to balance the mass of the first chuck. When the first chuck is asymmetric, the position of the counterweight hole can be changed to keep the center of gravity of the first chuck as a whole on the axis of the probe and the first connecting part after clamping the probe, thereby ensuring the subsequent stable operation of the first chuck, such as the balanced stability of rotation.
[0010] Furthermore, the first tension adjusting member includes an operating portion and a connecting portion that are connected, the connecting portion is arranged through the first clamping portion, the first deformation groove and the second clamping portion, and the operating portion is used to rotate and operate to adjust the width of the first deformation groove. The first tension adjusting member and the first deformation groove cooperate to change the size of the clamping space between the first clamping portion and the second clamping portion, thereby achieving clamping and loosening of the probe, and the setting of the operating portion facilitates the operation of adjusting the tension of the first deformation groove.
[0011] Furthermore, the first clamping part and the second clamping part have flush surfaces, and a retreat groove communicating with the first positioning part is provided in the middle of the surfaces. The retreat groove is provided to provide space for clamping the probe, and can avoid the position of the sensing window of the probe, thereby providing space for dispensing operation.
[0012] Further, the first positioning portion is an arc concave surface that fits the outer wall of the probe, and the first positioning portion is sequentially connected by the first arc positioning portion, the second arc positioning portion and the third arc positioning portion, and the height of the second arc positioning portion is flush with the height of the retreat groove and is lower than the first arc positioning portion and the third arc positioning portion. The first arc positioning portion, the second arc positioning portion and the third arc positioning portion are shaped like a partial arc surface of the outer circumference of the probe to facilitate stable clamping.
[0013] The present invention also provides an assembly device for a micro pressure sensor probe, comprising a second chuck, a second tension adjustment member and the probe clamping device as described above, wherein the second chuck comprises a clamping rod, a second connecting portion and a plurality of clamping jaws connected in sequence, the clamping rod and the second connecting portion are provided with a through hole for allowing a catheter to pass through, the clamping jaws are closed to form a positioning hole that fits the outer wall of the catheter, and the through hole is coaxially connected to the positioning hole; second deformation grooves are provided between adjacent clamping jaws, and flexible clamping of the catheter is achieved by tightening the second deformation grooves through the second tension adjustment member.
[0014] The assembly device of the micro pressure sensor probe of the present invention operates the second tension adjustment piece to change the width of the second deformation groove between each clamping jaw, and the diameter of the positioning hole changes accordingly until the inner wall surface of the clamping jaw is in circumferential contact with the outer peripheral surface of the catheter, thereby realizing flexible clamping of the catheter. It has the advantages of uniform force, strong adaptability, simple operation, and no damage to the catheter, and can effectively avoid deformation, bending, and deflection during the catheter clamping process.
[0015] Furthermore, the second deformation groove is partially located between adjacent clamping jaws, and partially opened at the end of the second connecting portion; the outer periphery of the second connecting portion is provided with an external thread, and the second tension adjustment member is a cap provided with an internal thread, and the cap is threadedly connected to the second connecting portion. The cap and the second connecting portion are tightened or loosened to achieve clamping and loosening of the catheter, and the operation is simple and convenient.
[0016] Furthermore, it also includes a first mounting frame, a second mounting frame and a displacement adjustment platform, wherein the first chuck is mounted on the first mounting frame, the second chuck is mounted on the second mounting frame, and one of the first mounting frame and the second mounting frame is mounted on the displacement adjustment platform. The displacement adjustment of the probe and the catheter in different directions is achieved by setting the displacement adjustment platform, thereby achieving the centering assembly of the catheter and the probe.
[0017] Furthermore, the displacement adjustment platform includes a first motion platform and a second motion platform, wherein the motion direction of the first motion platform is the axial direction of the probe and the catheter; the second motion platform is mounted on the first motion platform, and the motion direction of the second motion platform is the height direction perpendicular to the axial direction of the probe and the catheter. The axial distance between the catheter and the probe is achieved through the first motion platform; the height adjustment of the probe or catheter is achieved through the second motion platform, thereby achieving the alignment of the catheter and the probe in height.
[0018] Furthermore, the second mounting bracket is mounted on the displacement adjustment platform, and the second motion platform includes a fixed block and an inclined slot fixedly mounted on the first motion platform, an adjusting member rotatably mounted on the fixed block, and an inclined sliding block provided on the second mounting bracket, one end of the adjusting member abuts against the inclined sliding block, and the inclined sliding block is slidably connected to the inclined slot. During the centering assembly, the position of the probe remains unchanged, the catheter is moved closer to the probe through the first motion platform, the height of the catheter is adjusted to the same height as the probe through the second motion platform, and finally the catheter is extended into a specific position of the probe through the first motion platform.
[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0041] Embodiment 1
[0042] The present embodiment is the first embodiment of the clamping device for the micro pressure sensor probe, including a first clamp 100 and a first tension adjustment member 200. The first clamp 100 includes a first connecting portion 120, a first clamping portion 130 and a second clamping portion 140. The first clamping portion 130 and the second clamping portion 140 are both connected to the first connecting portion 120 and are located on the same side of the first connecting portion 120. A first deformation groove 150 that is interconnected and a first positioning portion 110 for accommodating the probe 910 are provided between the first clamping portion 130 and the second clamping portion 140. The flexible clamping of the probe 910 is achieved by tightening the first deformation groove 150 through the first tension adjustment member 200. In this embodiment, the first deformation groove 150 is a small gap, located below the first positioning portion 110 or below the first positioning portion 110 and on one side close to the first connecting portion, which not only provides space for the deformation clamping of the chuck, but also when the clamping force is too large during the locking process, the gaps around the first positioning portion 110 are merged together, which can prevent the clamping force from continuing to act on the probe 910, further protecting the probe 910 from damage, and better achieving flexible clamping of the probe. The first deformation groove 150 separates the first clamping portion 130 and the second clamping portion 140, which can reduce the use of other components, effectively reduce the overall volume space, and greatly reduce the complexity of the tooling.
[0043] When this embodiment is implemented, the first tension adjusting member 200 cooperates with the first deformation groove 150 to change the size of the clamping space between the first clamping portion 130 and the second clamping portion 140. The first clamping portion 130 and / or the second clamping portion 140 deforms when subjected to force and returns to its original state after the external force is removed, thereby achieving flexible clamping and release of the probe 910. Figure 1 , Figure 2 shown.
[0044] In this embodiment, the width of the first deformation groove 150 is smaller than that of the first positioning portion 110 , especially the width of the connection between the first deformation groove 150 and the first positioning portion 110 is smaller, which can prevent the probe from falling into the first deformation groove 150 when initially placed.
[0045] In this embodiment, the first connecting portion 120 is a cylindrical structure, the first clamping portion 130 and the second clamping portion 140 are fan-shaped structures, and the two are surrounded by a semi-cylindrical structure; the first clamping portion 130 and the second clamping portion 140 can be made of metal materials with good deformation ability. When the first chuck 100 is processed and formed, this embodiment can be obtained by cutting on a cylindrical structure and then processing the slot. The first chuck 100 designed in this way is not a centrally symmetrical structure, and its center of gravity will be offset. In this embodiment, in order to balance the mass of the first chuck 100 to ensure the balance of the operation of the first chuck 100, a counterweight hole 160 is provided in the first connecting portion 120, and a counterweight block, lead mud and other objects with relatively high density are added in the counterweight hole 160. The first clamping portion 130 and the second clamping portion 140 have a flush surface, and the middle of the surface is provided with a retreat groove 170 connected to the first positioning portion 110. The setting of the retreat groove 170 provides space for clamping the probe 910, improving the operation efficiency; at the same time, it can avoid the position of the sensing window 911 of the probe 910, providing space for subsequent dispensing operations. The retreat groove of the present invention can be set according to the space required for the installation operation of the probe 910.
[0046] In this embodiment, the first positioning portion 110 is a first positioning groove, and the surfaces of the first clamping portion 130 and the second clamping portion 140 are both provided with a retreat groove 170 connected to the middle of the first positioning groove. The first deformation groove 150, the first positioning groove and the retreat groove 170 are connected, and the retreat groove 170 is located in the middle of the surface flush with the first clamping portion 130 and the second clamping portion 140. The first deformation groove 150 is located in the radial direction of the first clamping head 100, and the first positioning groove is located in the axial direction of the first clamping head 100, which is obtained by profiling processing; the axis of the retreat groove 170 is perpendicular to the axis of the first positioning groove, and the retreat groove 170 is in two groups, and the two groups of retreat grooves 170 are symmetrical on both sides of the first positioning groove. The first positioning groove includes a first arc positioning portion 111, a second arc positioning portion 112 and a third arc positioning portion 113 which are arranged in sequence. The first arc positioning portion 111, the second arc positioning portion 112 and the third arc positioning portion 113 are shaped like a partial arc surface of the outer circumferential surface of the probe 910. When the probe 910 is clamped and positioned, the end face of the probe 910 abuts against the end face of the first positioning groove to achieve axial positioning of the probe 910.
[0047] Specifically, the height of the second arc positioning portion 112 is flush with the height of the retreat groove 170 and is lower than the first arc positioning portion 111 and the third arc positioning portion 113. Figure 1As shown, the top edges of the first arc positioning portion 111 and the third arc positioning portion 113 are higher than half the height of the outer circumference of the probe 910 to facilitate stable clamping; the top edge of the second arc positioning portion 112 is lower than half the height of the outer circumference of the probe 910 to provide space for clamping the probe 910, while avoiding the position of the sensing window 911 of the probe 910 to provide space for subsequent dispensing operations.
[0048] The specific implementation steps of this embodiment are as follows:
[0049] The first tension adjusting member 200 is loosened to restore the first deformation groove 150 to its initial state, and the probe 910 is clamped in the first positioning groove. During the clamping process, the clamping personnel's fingers or clamping tools extend into the retreat groove 170, and the end face of the probe 910 is positioned against the end face of the first positioning groove; then the first tension adjusting member 200 is locked to deform the first deformation groove 150, and the first positioning groove is tightened, thereby clamping the probe 910. The first chuck 100 of this embodiment is convenient to clamp, and the position of the sensing window 911 of the probe 910 can be avoided when clamping the probe 910. The probe 910 is clamped in the form of a cover by contouring, and the probe 910 is evenly stressed and will not be deformed or damaged when clamped. It can adapt to the clamping of workpieces with small probe volume and small clamping surface such as micro pressure sensors.
[0050] Embodiment 2
[0051] This embodiment is the second embodiment of the clamping device for the micro pressure sensor probe. This embodiment is similar to the first embodiment, except that, in this embodiment, the difference in the deformation capacity of the first clamping part 130 and the second clamping part 140 is further improved by the difference in the stiffness of the first clamping part 130 or the second clamping part 140. The stiffness of the first clamping part 130 is greater than the stiffness of the second clamping part 140, or the stiffness of the second clamping part 140 is greater than the stiffness of the first clamping part 130. The first clamping part 130 and the second clamping part 140 have different stiffnesses, and one of the first clamping part 130 and the second clamping part 140 retains stiffness and the other clamping part improves deformation capacity, so that the probe 910 has a reference to rely on during the clamping process, thereby effectively improving the positioning accuracy. This embodiment is described by taking the case where the stiffness of the second clamping part 140 is less than the stiffness of the first clamping part 130 as an example.
[0052] In this embodiment, the deformation capabilities of the first clamping part 130 and the second clamping part 140 can be differentiated by the material settings of the first clamping part 130 and the second clamping part 140. For example, the first clamping part 130 is formed of a rigid material and the second clamping part 140 is prepared from an easily deformable material. Under the action of the first tension adjustment member 200, the second clamping part 140 is deformed and approaches the first clamping part 130. For the convenience of processing, the first clamping part 130 and the second clamping part 140 are often formed of the same material. In this embodiment, the first clamping part 130 and the second clamping part 140 are both formed of metal materials. At this time, the rigidity of the second clamping part 140 can be reduced by removing material.
[0053] In the present invention, the portion of the second clamping portion 140 where material is removed may be a portion of the second clamping portion 140, or the entire cross-sectional area of the second clamping portion 140 (equivalent to thinning the entire thickness of the second clamping portion 140). In order to facilitate the processing and forming of the first clamping head 100, the thinned area in this embodiment is the entire cross-sectional area of the second clamping portion 140, and the cutting and forming can be performed along the axial direction of the first clamping head 100 during the forming process. Figure 3 , 4 shown.
[0054] Due to the material removal design of the second clamping part 140, the center of gravity of the first clamp 100 of this embodiment will be offset, which will destroy the symmetry of the first clamp 100 and affect the rotation balance of the first clamp 100 in subsequent operations. In this embodiment, the operating part 210 of the first tension adjustment member 200 is set on one side of the second clamping part 140, which can avoid the problem of the center of gravity offset of the first clamp 100 caused by the thinning design of the second clamping part 140 to a certain extent. At the same time, this embodiment can change the position of the counterweight hole 160 to keep the center of gravity of the first clamp 100 as a whole located on the axis of the probe 910 and the first connecting part 120 after clamping the probe 910, so as to ensure the balance of the operation of the first clamp 100.
[0055] The specific implementation steps of this embodiment are similar to those of the first embodiment, except that:
[0056] Due to the material removal design of the second clamping portion 140, when locking the first tension adjustment member 200, the second clamping portion 140 is more likely to deform relative to the first clamping portion 130, which can facilitate the clamping operation of the probe 910 and effectively prevent the probe 910 from being damaged or deformed during the clamping process.
[0057] Since the operating portion 210 of the first tension adjusting member 200 is disposed on one side of the second clamping portion 140, the problem of the center of gravity of the first clamp 100 being offset due to the thinning design of the second clamping portion 140 can be avoided to a certain extent. In addition, by changing the position of the counterweight hole 160, the center of gravity of the first clamp 100 as a whole is kept on the axis of the probe 910 and the first connecting portion 120 after clamping the probe 910, so as to ensure the balance of the operation of the first clamp 100.
[0058] Embodiment 3
[0059] This embodiment is the third embodiment of the clamping device for the micro pressure sensor probe. This embodiment is similar to the first embodiment or the second embodiment, except that, in this embodiment, the first deformation groove 150 is connected with a deformation hole 180, and the deformation hole 180 can be specifically arranged on the side of the first deformation groove 150 close to the first connecting portion, and can be arranged between the first clamping portion 130 and the second clamping portion 140. Through the design of the deformation hole 180, the deformation capacity of the first clamping portion 130 and the second clamping portion 140 can be improved.
[0060] Specifically, the deformation hole 180 is partially set through the first clamping portion 130 and partially set through the second clamping portion 140. The deformation hole 180 may preferably be a cylindrical hole, the axis of the cylindrical hole is perpendicular to the axis of the first locking hole 131 and the second locking hole 141, the axis of the cylindrical hole is vertically arranged, and the cylindrical hole is symmetrical about the central plane of the first deformation groove 150, such as Figure 3 , 4 shown.
[0061] The specific implementation steps of this embodiment are similar to those of Embodiment 1 or Embodiment 2, except that:
[0062] Since the deformation hole 180 and the first deformation groove 150 are connected, when the first tension adjustment member 200 is locked, the first clamping portion 130 and the second clamping portion 140 are more likely to deform, which can facilitate the clamping operation of the probe 910 and also avoid damage and deformation of the probe 910 during the clamping process to a certain extent.
[0063] Embodiment 4
[0064] This embodiment is the fourth embodiment of the clamping device for the micro pressure sensor probe. This embodiment is similar to any one of the first to third embodiments, except that, in this embodiment, the first tension adjustment member 200 is specifically designed and the retreat groove 170 is through-designed.
[0065] In this embodiment, the first tension adjusting member 200 includes an operating portion 210 and a connecting portion 220 connected to each other. Figure 5The connecting portion 220 is arranged through the first clamping portion 130, the first deformation groove 150 and the second clamping portion 140, and the operating portion 210 is used for rotating and adjusting the width of the first deformation groove 150. The first clamping portion 130 is provided with a first locking hole 131, and the second clamping portion 140 is provided with a second locking hole 141.
[0066] Specifically, one of the first locking hole 131 and the second locking hole 141 can be set as a threaded hole and the other hole can be set as a light hole. The threaded hole is generally set at a clamping part away from the operating part 210. The first tension adjusting member 200 is a bolt, and the threaded part of the bolt serves as the connecting part 220, and the nut part of the bolt serves as the operating part 210. The threaded part of the bolt passes through the light hole and is threadedly connected with the threaded hole. Figure 4 As shown. At this time, the rotating operating part 210 will drive a clamping part threadedly connected to the connecting part 220 to move linearly, so that the first deformation groove 150 is deformed and the first positioning groove is tightened, thereby clamping the probe 910. In addition, the first locking hole 131 and the second locking hole 141 can also be set as light holes. The diameter of the operating part 210 of the first tension adjustment member 200 is larger than the diameter of the connecting part 220. The end of the connecting part 220 away from the operating part 210 is provided with an external thread. The connecting part 220 passes through the first clamping part 130 and the second clamping part 140 and is threadedly connected to the nut. During implementation, the nut is tightened, the first deformation groove 150 is deformed, and the first positioning groove is tightened, thereby clamping the probe 910.
[0067] The first clamping portion 130 and the second clamping portion 140 have flush surfaces, and a retreat groove 170 communicating with the first deformation groove 150 is opened in the middle of the surface. The retreat groove 170 in this embodiment runs through the first clamping portion 130 and the second clamping portion 140. Figure 6 As shown. The retreat groove 170 divides the first positioning portion 110 of the first deformation groove 150 into a first arc positioning portion 111, a second arc positioning portion 112 and a third arc positioning portion 113 which are arranged in sequence, wherein the first arc positioning portion 111 and the third arc positioning portion 113 are shaped like partial arc surfaces of the outer peripheral surface of the probe 910, and the middle portion of the probe 910 is suspended in the retreat groove 170. When the probe 910 is clamped and positioned, the end face of the probe 910 is abutted against the end face of the third arc positioning portion 113 by clamping the middle portion of the probe 910 radially with tweezers, so as to achieve the axial positioning of the probe 910. This design allows a larger operating space for the probe 910 and facilitates the clamping and positioning operation of the probe 910.
[0068] The specific implementation steps of this embodiment are similar to those of any one of Embodiments 1 to 3, except that:
[0069] Since the first tension adjustment member 200 includes an operating part 210 and a connecting part 220 which are connected to each other, the connecting part 220 passes through the first clamping part 130, the first deformation groove 150 and the second clamping part 140 to form a first locking hole 131 and a second locking hole 141, and one of the holes is set as a threaded hole, the tightening and loosening of the first deformation groove 150 can be adjusted by rotating the operating part 210.
[0070] Since the middle of the probe 910 is suspended in the retreat groove 170 , the operator can use tweezers to clamp the middle of the probe 910 along the direction of the retreat groove 170 , that is, from the radial direction of the probe 910 , which makes it easier to clamp and adjust the position and angle of the probe 910 .

[0072] This embodiment is the first embodiment of the assembly device of the micro pressure sensor bougie 900, comprising a second clamp 300, a second tension adjusting member 400, and a probe 910 clamping device as described in any one of Embodiments 1 to 4. This embodiment is used to align the probe 910 and the catheter 920 to obtain the micro pressure sensor bougie 900.
[0073] In this embodiment, the second clamp 300 includes a clamp rod 320, a second connecting portion 330 and a plurality of clamping jaws 350 connected in sequence, the clamp rod 320 and the second connecting portion 330 are provided with a through hole for allowing the catheter 920 to pass through, the second positioning portion 310 is a positioning hole 310 formed between the plurality of clamping jaws 350, and the through hole is coaxially connected to the positioning hole 310; a second deformation groove 340 is provided between adjacent clamping jaws 350, and a plurality of the clamping jaws 350 are detachably connected with a second tension adjusting member 400, and the flexible clamping of the catheter 920 is achieved by tightening the second deformation groove 340 through the second tension adjusting member 400, such as Figure 7 , 8 The second tension adjusting member 400 cooperates with the second deformation groove 340 to change the size of the positioning hole 310 between the clamping jaws 350, thereby clamping and releasing the catheter 920; the through hole and the positioning hole 310 are connected, and the catheter 920 sequentially passes through the through hole in the clamp rod 320, the through hole in the second connecting part 330, and the positioning hole 310, and partially extends out of the positioning hole 310.
[0074] Among them, Figure 8As shown, the second deformation groove 340 is partially located between adjacent clamping jaws 350, and partially opened at the end of the second connecting portion 330; the outer periphery of the second connecting portion 330 is provided with an external thread, and the second tension adjusting member 400 is a cap provided with an internal thread, and the cap is threadedly connected to the second connecting portion 330; the end of the cap is also provided with a through hole for allowing the catheter 920 to pass through. Specifically, the second deformation groove 340 is partially opened at the end of the second connecting portion 330, and multiple parts of the end of the second connecting portion 330 simultaneously serve as the root of the clamping jaw 350. The thread diameter of the root of the clamping jaw 350 is slightly larger than the thread diameter of the external thread of the second connecting portion 330. When this embodiment is implemented, the cap and the second connecting portion 330 are tightened or loosened to achieve clamping and loosening of the catheter 920, which is easy to operate.
[0075] In addition, in this embodiment, there are four groups of clamping jaws 350, and the four groups of clamping jaws 350 are surrounded to form a truncated cone structure, and the inner wall surface of each group of clamping jaws 350 is a circular arc surface that fits the outer circumference of the catheter 920. The four groups of circular arc surfaces surround a positioning hole 310, and when there is no external force, the diameter of the positioning hole 310 is slightly larger than the diameter of the catheter 920, so as to facilitate the installation of the catheter 920; after the catheter 920 is installed, the cap is connected to the second connecting part 330, and the second deformation groove 340 is tightened under the action of external force, thereby achieving stable clamping of the catheter 920.
[0076] The specific implementation steps of this embodiment are similar to those of any one of Embodiments 1 to 4, except that:
[0077] The catheter 920 is sequentially passed through the inner hole of the clamp rod 320, the inner hole of the second connecting part 330 and the positioning hole 310, and partially extends out of the positioning hole 310. The hollow four claws on the outer periphery of the positioning hole 310 ensure the centering of the catheter 920; the cap is screwed tightly with the second connecting part 330, and the clamping claws 350 are evenly clamped on the outer periphery of the catheter 920 to avoid deflection caused by deformation, bending, etc. during the clamping process, thereby effectively ensuring the accuracy of assembly of the catheter 920 and the probe 910.
[0078] Embodiment 6
[0079] This embodiment is a second embodiment of an assembly device for a micro pressure sensor bougie 900. This embodiment is similar to the fifth embodiment, except that it further includes a first mounting frame 500, a second mounting frame 600, and a displacement adjustment platform 700, and the first chuck 100 is mounted on the first mounting frame 500, the second chuck 300 is mounted on the second mounting frame 600, and one of the first mounting frame 500 and the second mounting frame 600 is mounted on the displacement adjustment platform 700. Fig. 9 shown.
[0080] In this embodiment, a bottom plate 800 is also included. Specifically, in this embodiment, the bottom plate 800 can be set as a square plate, which mainly plays the role of integrating the first chuck 100, the second chuck 300, the first mounting frame 500, the second mounting frame 600 and the displacement adjustment platform 700. Fig. 9 As shown. In order to realize the centering of the probe 910 and the catheter 920, at least one of the first chuck 100 and the second chuck 300 needs to move. Therefore, in this embodiment, at least one mounting frame 720 of the first mounting frame 500 and the second mounting frame 600 is installed on the displacement adjustment platform 700. When one of the first mounting frame 500 and the second mounting frame 600 is installed on the displacement adjustment platform 700, and the other of the first mounting frame 500 and the second mounting frame 600 is fixedly installed on the bottom plate 800, the positions of the probe 910 and the catheter 920 are one moving and one static, which can reduce the difficulty of centering; when the first mounting frame 500 and the second mounting frame 600 are both installed on the displacement adjustment platform 700, the positions of the probe 910 and the catheter 920 can both move, which can improve the centering accuracy.
[0081] For ease of description, in this embodiment, the micro pressure sensor probe clamping device is placed in an XYZ three-dimensional coordinate system, and the axial direction of the probe 910 and the catheter 920 is the X direction. In this embodiment, the displacement adjustment platform 700 can be a single-degree-of-freedom adjustment platform, a double-degree-of-freedom adjustment platform, or a three-degree-of-freedom adjustment platform. Specifically:
[0082] When the displacement adjustment platform 700 is a single-degree-of-freedom platform, the movement direction of the displacement adjustment platform 700 should specifically be the X direction, so that the catheter 920 and the probe 910 can be brought close to each other; the Y-direction and Z-direction alignment of the probe 910 and the catheter 920 is achieved by the centering installation of the first chuck 100 and the second chuck 300, and there is no need to perform the Y-direction and Z-direction alignment of the catheter 920 and the probe 910 during the assembly process, which is easy to operate. The single-degree-of-freedom platform of this embodiment can specifically be a linear module or a single-degree-of-freedom motion structure similar to a linear module.
[0083] When the displacement adjustment platform 700 is a dual-degree-of-freedom platform, one of the degrees of freedom should be the movement in the X direction, and the other degree of freedom can be the movement in the Z direction or the movement in the Y direction. If the other degree of freedom is the movement in the Z direction, the alignment of the catheter 920 and the probe 910 in the Z direction can be achieved; if the other degree of freedom is the movement in the Y direction, the alignment of the catheter 920 and the probe 910 in the Y direction can be achieved. In this embodiment, the alignment of the probe 910 and the catheter 920 in the Y direction can be performed when the first mounting frame 500 and the second mounting frame 600 are installed, and there is no need to align the Y direction during assembly; the alignment of the probe 910 and the catheter 920 in the Z direction is achieved by the displacement adjustment platform 700, so as to avoid the situation that the first chuck 100 and the second chuck 300 are not aligned in the height direction when clamping probes 910 and catheters 920 of different sizes. The dual-degree-of-freedom platform of this embodiment can be specifically a linear module or a dual-degree-of-freedom motion structure similar to a linear module.
[0084] When the displacement adjustment platform 700 is a three-degree-of-freedom platform, the three degrees of freedom are movement in the X direction, movement in the Y direction, and movement in the Z direction. The arrangement of the displacement adjustment platform 700 can not only realize the alignment of the probe 910 and the catheter 920 in the three directions of X, Y, and Z, but also realize the assembly of the probe 910 and the catheter 920 close to each other. The three-degree-of-freedom platform in this embodiment can specifically select a high-precision three-axis positioning platform to ensure the stability of the assembly process.
[0085] The specific implementation steps of this embodiment are similar to those of the fifth embodiment, except that:
[0086] The probe 910 is clamped by the first chuck 100, and the catheter 920 is clamped by the second chuck 300. The first positioning portion 110 of the first chuck 100 contacts the outer peripheral surface of the probe 910, and the second positioning portion 310 of the second chuck 300 contacts the outer peripheral surface of the catheter 920. The first chuck 100 and the second chuck 300 are highly adaptable, easy to operate, and non-destructive to the workpiece, and can effectively prevent the probe 910 and the catheter 920 from being easily deformed and damaged during assembly and clamping; at least one of the first chuck 100 and the second chuck 300 can move relative to the base plate 800, thereby realizing the coaxial alignment assembly of the probe 910 and the catheter 920.
[0087] Embodiment 7
[0088] This embodiment is the third embodiment of the assembly device of the micro pressure sensor bougie 900. This embodiment is similar to the sixth embodiment, except that in this embodiment, the first mounting frame 500 is mounted on the bottom plate 800, and the second mounting frame 600 is mounted on the displacement adjustment platform 700. When this embodiment is implemented, the probe 910 remains stationary, and the catheter 920 moves to align with the probe 910 and is assembled.
[0089] In this embodiment, the displacement adjustment platform 700 includes a first motion platform 710, and the motion direction of the first motion platform 710 is the axial direction of the probe 910 and the catheter 920, that is, the X direction. During the centering assembly of this embodiment, the position of the probe 910 remains unchanged, and the catheter 920 is moved closer to the probe 910 through the first motion platform 710 until the catheter 920 is inserted into a specific position inside the probe 910.
[0090] When assembling micro pressure sensor bougies 900 of different models and sizes, the axes of the probe 910 and the catheter 920 may be misaligned in the height direction. Therefore, the height of the catheter 920 needs to be adjusted in this embodiment. In this embodiment, the displacement adjustment platform 700 also includes a second motion platform 720 installed on the first motion platform 710. The motion direction of the second motion platform 720 is the height direction perpendicular to the axial direction of the probe 910 and the catheter 920, that is, the Z direction. The second motion platform 720 realizes the height adjustment of the catheter 920, thereby realizing the alignment of the two devices, the catheter 920 and the probe 910, in the height position.
[0091] In addition, in this embodiment, the second motion platform 720 includes a fixed block 721 and an inclined groove 722 fixedly mounted on the first motion platform 710, an adjusting member 723 rotatably mounted on the fixed block 721, and an inclined slider 724 provided on the second mounting frame 600, one end of the adjusting member 723 abuts against the inclined slider 724, and the inclined slider 724 is slidably connected to the inclined groove 722. The slidable connection between the inclined slider 724 and the inclined groove 722 is actually to smoothly and efficiently convert the horizontal movement of the adjusting member 723 into the movement in the height direction of the second chuck 300 through the cooperation of an inclined surface provided on the inclined slider 724 and an inclined surface located in the inclined groove 722, as shown in FIG. Fig.10 As shown. In this embodiment, the horizontal movement of the adjusting member 723 is converted into movement in the height direction by the inclined surface cooperation between the inclined slider 724 and the inclined groove 722. The height adjustment process is stable and high-precision fine adjustment can be achieved. In order to ensure the stability of the sliding between the inclined slider 724 and the inclined groove 722, in this embodiment, limit blocks are arranged on both sides of the inclined slider 724, and limit grooves slidably connected to the limit blocks are arranged on both sides of the inclined groove 722. The arrangement of the limit grooves and the limit blocks can effectively prevent the inclined slider 724 from sliding off the inclined groove 722.
[0092] The specific implementation steps of this embodiment are similar to those of the sixth embodiment, except that:
[0093] The first motion platform 710 is installed on the base plate 800, and is used to drive the second motion platform 720 and all the components thereon to move along the X direction; the second motion platform 720 is installed on the first motion platform 710, and is used to drive the second chuck 300 and the catheter 920 clamped thereon to move along the Z direction; after the catheter 920 and the probe 910 are clamped, the height of the second chuck 300 and the catheter 920 clamped thereon are adjusted by the second motion platform 720 so that the catheter 920 and the probe 910 are aligned; after the alignment is completed, the second motion platform 720 and all the components thereon are driven to move along the X direction by controlling the first motion platform 710 until the catheter 920 is extended into the probe 910 by a set distance.
[0094] Embodiment 8
[0095] This embodiment is a fourth embodiment of an assembly device for a micro pressure sensor bougie 900. This embodiment is similar to the seventh embodiment, except that the first chuck 100 is connected to a first motor 190, the second chuck 300 is connected to a second motor 360, the first motor 190 and the second motor 360 are both servo motors, and the first motor 190 and the second motor 360 rotate synchronously. Fig. 9 The dual-motor synchronous control method can not only retain the movement flexibility of the probe 910 and the catheter 920, but also ensure that during the spin coating process after assembly, the probe 910 and the catheter 920 can be highly consistent in parameters such as speed, position and torque, and achieve synchronous rotation, thereby achieving automatic spin coating at the connection between the probe 910 and the catheter 920.
[0096] The synchronously rotating object probe 910 and catheter 920 of the present invention have small size and limited space, and are required to be able to be flexibly separated and combined during assembly. Whether it is a traditional single motor drive or a cylinder drive, a single power source requires the introduction of a complex mechanism for transmission. The introduction of a complex transmission mechanism will lead to problems such as large tooling volume, poor reliability, and high cost. The above problems can be avoided by adopting a dual-motor synchronous control method. The dual-motor design makes the overall tooling volume small, saves production operation space, and is also conducive to transfer during the production process.
[0097] Specifically, in this embodiment, the tail of the first chuck 100 is the rotating shaft 121, the first motor 190 is mounted on the first mounting frame 500, and the output shaft of the first motor 190 passes through the first mounting frame 500 and is connected to the rotating shaft 121. In order to ensure the coaxial and stable connection between the rotating shaft 121 and the output shaft of the first motor 190, a coupling is connected between the rotating shaft 121 and the output shaft of the first motor 190 in this embodiment. The tail of the second chuck 300 is the clamping rod 320. Since the conduit 920 passing through the clamping rod 320 is easy to deform and bend, the length of the clamping rod 320 needs to be set long enough to avoid the deflection of the conduit 920 during the centering process, and the second motor 360 cannot be directly mounted on the second mounting frame 600. Therefore, in this embodiment, the second mounting frame 600 is a bearing seat, the clamping rod 320 passes through the bearing seat, and a transmission structure is connected between the clamping rod 320 and the second motor 360. Specifically, the transmission structure of this embodiment is a belt transmission structure, a driven pulley is connected to the outer periphery of the clamping rod 320, the second motor 360 is installed on the first motion platform 710, the output shaft of the second motor 360 is connected to the driving pulley, and the driving pulley and the driven pulley are driven by a belt. In addition to the belt transmission, other transmission structures such as chain transmission and gear transmission can also be applied.
[0098] The specific implementation steps of this embodiment are similar to those of the seventh embodiment, except that:
[0099] The probe 910 is driven to rotate by the first motor 190, and the catheter 920 is driven to rotate by the second motor 360. Both the first motor 190 and the second motor 360 are servo motors. The master-slave synchronous control function mode is used to achieve high-precision and high-stability coordinated movement between the two.
[0100] Embodiment 9
[0101] This embodiment is a ninth embodiment of an assembly device for a micro pressure sensor bougie 900. This embodiment is similar to the eighth embodiment, except that it includes a frame 810 and a dispensing assembly 820 mounted on the frame 810. Fig.12 The dispensing assembly 820 is disposed above the first chuck 100 and the second chuck 300 , and the dispensing assembly 820 is aligned with the sensing window 911 of the probe 910 and the joint between the probe 910 and the conduit 920 to dispense glue.
[0102] The sensing window 911 of the probe 910 is encapsulated as glue dispensing on a horizontal plane, and the connection between the rear end of the probe 910 and the conduit 920 needs to be rotated and coated in a ring. The glue used in the two places is different and the glue dispensing methods are different. In this embodiment, the glue dispensing component 820 is a rotary double-headed glue dispensing component 820, and the mounting frame 810 is provided with a lifting component 830, and the glue dispensing component 820 is arranged at the output end of the lifting component 830.
[0103] Specifically, the dispensing assembly 820 includes a mounting plate 821, a first glue head 822 and a second glue head 823 mounted on the front of the mounting plate 821, wherein the axis of the first glue head 822 is perpendicular to the axis of the second glue head 823; and further includes a rotating cylinder 824 mounted on the back of the mounting plate 821, wherein the rotating cylinder 824 is mounted at the output end of the lifting assembly 830, such as Fig.11 By controlling the rotary cylinder 824 to rotate and change the positions of the first glue head 822 and the second glue head 823, the glue dispensing assembly 820 can be effectively prevented from interfering with and colliding with other components during the glue dispensing process, and the design of this rotary double-head glue dispensing mechanism can reduce the volume of the tooling.
[0104] In this embodiment, the positions of the first glue head 822 and the second glue head 823 before and after the rotation switching can be located at the same position. In this case, the dispensing position before and after the rotation switching can also be changed by setting the third motion platform 840, so that the first glue head 822 and the second glue head 823 before and after the rotation switching correspond to the position of the sensing window 911 and the position of the connection between the catheter 920 and the probe 910, respectively. Fig.12 shown.
[0105] The specific implementation steps of this embodiment are similar to those of the eighth embodiment, except that:
[0106] The first glue head 822 contains the packaging material of the sensing window 911, and the second glue head 823 contains the packaging material of the connection between the catheter 920 and the probe 910; when the sensing window 911 needs to be packaged first, the position of the first glue head 822 is adjusted by the lifting component 830 and the third motion platform 840, so that the discharge port of the first glue head 822 is aligned with the sensing window 911, and the packaging material in the first glue head 822 is pushed out to complete the packaging of the sensing window 911; then the position of the connection between the catheter 920 and the probe 910 is packaged, and the position of the second glue head 823 is adjusted by the lifting component 830 and the third motion platform 840, so that the discharge port of the second glue head 823 is aligned with the connection position between the catheter 920 and the probe 910, and the packaging material in the second glue head 823 is pushed out, and at the same time, the probe 910 and the catheter 920 are controlled to rotate synchronously by the dual motors to complete the spin coating at the connection position between the catheter 920 and the probe 910.
[0107] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0108] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
