Description

Technical Field

[0001] The present invention relates to the technical field of micro pressure sensor bougie packaging, and more specifically, to an assembly and dispensing integrated device. Background Art

[0002] As a kind of precision sensor technology, micro pressure sensors are increasingly widely used in the field of medical devices. However, they are small in size and precise in structure. They are easily damaged in a series of processing processes such as assembly and packaging. The lack of automated production equipment has brought difficulties to industrialization. The present invention takes the micro sensor probe for measuring intracranial pressure as an example. The micro sensor probe for measuring intracranial pressure includes two parts: a probe and a catheter. Since it is used in delicate intracranial tissues, the probe has very small dimensions, usually only φ1mm, and cannot be produced automatically. It completely relies on skilled workers to manually assemble and dispense glue under a microscope, so the requirements for the packaging process are very strict.

[0003] The probe of the micro pressure sensor bougie has a sensor fixed inside, and the sensor is connected to a wire, which is set in a catheter, and the catheter is connected to the rear end of the probe. In this way, the preparation of the micro pressure sensor bougie requires the probe and the catheter to be assembled and fixed with glue. Since the probe of the intracranial pressure measurement bougie product has a sensing window opening design, after the probe and the catheter are assembled, the sensing window must be sealed with glue, and the connection between the rear end of the probe and the catheter must be fixed with glue. Moreover, the two glue dispensing locations are different, the glue used is different, and the glue dispensing methods adopted are different. The encapsulation of the probe sensing window is glue dispensing on the horizontal plane, and the connection between the rear end of the probe and the catheter requires rotating ring coating. At present, the glue dispensing at the two locations needs to be completed in two steps. At present, the manual ring coating of the sensing window and the connection between the probe and the catheter is prone to the risk of insufficient or excessive glue on the glue surface, uneven glue, and easy introduction of bubbles that affect the firmness of the connection after curing. In addition, when the workpiece is subjected to rotary ring coating, it is difficult to achieve uniform coating at the joint manually, and the probe and the catheter are in two separate parts. During the spin coating and fixation process, any situation that causes the probe and the catheter to move relative to each other may damage the structure and function of the probe. For example, the asynchronous rotation of the two relative to the dispensing head will cause irreversible performance damage to the probe. Summary of the invention

[0004] The purpose of the present invention is to overcome the difficulties in assembling and dispensing glue on the micro pressure sensor probe in the prior art, the shortcomings of manual dispensing that easily lead to risks such as lack of glue or excess glue on the glue surface, uneven glue, and easy introduction of bubbles that affect the firmness of the connection after curing, and to provide an integrated assembly and dispensing device that can meet the requirements of dispensing glue on the probe sensing window and automatic dispensing glue on the rotating ring coating at the joint between the probe and the catheter.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The present invention provides an integrated assembly and dispensing device, comprising a frame and a dispensing component installed on the frame, wherein a first chuck and a second chuck are provided below the dispensing component, and the first chuck is used to clamp a probe, and the second chuck is used to clamp a catheter, and the dispensing component can be aligned with a probe sensing window and a joint between the probe and the catheter for dispensing.

[0007] In the integrated assembly and dispensing device of the present invention, the first chuck is used to clamp the probe, and the second chuck is used to clamp the catheter. The first chuck and the second chuck are arranged to realize the assembly of the probe and the catheter, and the dispensing assembly is arranged to align the probe sensing window and the probe and the catheter joint to dispense glue. The present invention integrates the centering assembly and dispensing packaging of the micro pressure sensor bougie into one, and can realize automatic dispensing of the sensing window position and automatic spin coating of the probe and the catheter connection position, thereby meeting the precision requirements of the micro pressure sensor bougie packaging.

[0008] Furthermore, the first chuck is rotatably mounted on the first mounting frame, the second chuck is rotatably mounted on the second mounting frame, and the first chuck and the second chuck rotate synchronously. The first chuck and the second chuck rotate synchronously to achieve automatic spin coating at the joint between the probe and the catheter.

[0009] Furthermore, the first chuck is connected to a first motor, the second chuck is connected to a second motor, both the first motor and the second motor are servo motors, and the first motor and the second motor rotate synchronously. The dual-motor synchronous control method can not only retain the movement flexibility of the probe and the catheter, but also ensure that the assembled probe and the catheter can be highly consistent in parameters such as speed, position and torque, and achieve synchronous rotation, thereby achieving automatic spin coating at the junction of the probe and the catheter.

[0010] Further, the tail of the first chuck is used as a rotating shaft, the output shaft of the first motor passes through the first mounting frame and is connected to the rotating shaft, and a coupling is connected between the rotating shaft and the output shaft of the first motor; and / or, the second mounting frame is a bearing seat, and the second chuck includes a clamping rod supporting the catheter, the clamping rod passes through the bearing seat, and a transmission structure is connected between the clamping rod and the second motor. The setting of the rotating shaft and the coupling facilitates the synchronous rotation connection between the first chuck and the first motor, the setting of the bearing seat facilitates the rotation installation of the second chuck and the second mounting frame, and the setting of the transmission structure facilitates the synchronous rotation connection between the second chuck and the second motor, thereby ensuring the synchronous rotation of the first chuck and the second chuck.

[0011] Furthermore, the dispensing assembly is a double-head dispensing assembly, which includes a mounting plate, a first glue head and a second glue head mounted on the front of the mounting plate, and a rotary cylinder mounted on the back of the mounting plate. By controlling the rotary cylinder to rotate and change the positions of the first glue head and the second glue head, interference and collision between the double-head dispensing assembly and other components can be effectively avoided during the dispensing process.

[0012] Furthermore, one of the first glue head and the second glue head is aligned with the sensing window of the probe to dispense glue; after rotation switching, the other glue head is aligned with the joint between the probe and the catheter to dispense glue. For example, the first glue head is first controlled to align with the sensing window of the probe to dispense glue, and after the rotary cylinder rotates, the second glue head is aligned with the joint between the probe and the catheter to dispense glue.

[0013] Furthermore, the axis of the first glue head is perpendicular to the axis of the second glue head. The axes of the first glue head and the second glue head are arranged perpendicularly, which can reduce the volume occupied by the double-head glue dispensing assembly while satisfying the rotation switching.

[0014] Furthermore, a first motion platform is included, one of the first chuck and the second chuck is installed on the first motion platform, and the motion direction of the first motion platform is the axial direction of the probe and the catheter. The first motion platform is set so that the catheter and the probe are moved closer to or farther from each other in the axial direction, thereby realizing the centering assembly of the catheter and the probe.

[0015] Furthermore, a third motion platform is installed on the first motion platform, and the motion direction of the third motion platform is a height direction perpendicular to the axial direction of the probe and the catheter. The third motion platform is provided so that the catheter and the probe are aligned with each other in the height direction, further ensuring the centering assembly of the catheter and the probe.

[0016] Furthermore, it also includes a second motion platform installed on the frame, the first motion platform is installed on the second motion platform together with another chuck not installed on the first motion platform, and the movement direction of the second motion platform is the width direction perpendicular to the axial direction of the probe and the conduit. The third motion platform is set to enable the conduit and the probe to move together in the width direction, thereby achieving alignment of the dispensing head that is about to dispense glue and the dispensing position in the double-head dispensing assembly in the width direction.

[0017] Furthermore, it also includes a lifting assembly installed on the frame, and the dispensing assembly is installed at the output end of the lifting assembly. The lifting assembly can control the lifting and lowering of the double-head dispensing assembly, thereby controlling the dispensing head of the double-head dispensing assembly that is about to dispense glue to approach or move away from the dispensing position in height, thereby achieving precise dispensing.

[0018] Furthermore, it also includes a fourth motion platform installed on the frame, the lifting assembly is installed at the output end of the fourth motion platform, and the movement direction of the fourth motion platform is the axial direction of the probe and the catheter. The fourth motion platform changes the position of the dispensing assembly in the axial direction, so that after rotating the dispensing head, the fourth motion platform is adjusted to ensure that the dispensing head is aligned with the dispensing position.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The assembly and dispensing integrated device of the present invention integrates the centering assembly and dispensing packaging of the micro pressure sensor bougie into one, and can realize automatic dispensing at the sensing window position and automatic spin coating at the connection position between the probe and the catheter, thereby meeting the precision requirements of the micro pressure sensor bougie packaging, effectively integrating and simplifying the multi-step process of assembly and dispensing, solving the problem of assembly and dispensing integration in the production process of the probe, and effectively improving the production efficiency;

[0021] The integrated assembly and dispensing device of the present invention adopts a dual-motor synchronous control method, which can not only maintain the movement flexibility of the probe and the catheter, but also ensure that the probe and the catheter after assembly can be highly consistent in parameters such as speed, position and torque, and realize synchronous rotation, thereby realizing automatic spin coating and dispensing at the joint between the probe and the catheter;

[0022] The integrated assembly and dispensing device of the present invention controls the rotation of the rotary cylinder to change the positions of the first and second glue heads by setting up the double-head dispensing assembly, which can effectively avoid interference and collision between the double-head dispensing assembly and other components during the dispensing process.

[0023] The integrated assembly and dispensing device of the present invention realizes the centering assembly of the probe and the catheter by setting the first motion platform, and realizes the alignment of the glue head and the dispensing position by the fourth motion platform, thereby ensuring accurate dispensing of the probe sensing window and the joint between the probe and the catheter;

[0037] Embodiment 1

[0038] This embodiment is the first embodiment of the integrated dispensing device for assembly, including a frame 100, a dispensing assembly 200 mounted on the frame 100, a first chuck 300 and a second chuck 400 are provided below the dispensing assembly 200, and the first chuck 300 is used to clamp the probe 310, and the second chuck 400 is used to clamp the conduit 410, and the dispensing assembly 200 can be aligned with the sensing window 320 of the probe 310 and the joint between the probe 310 and the conduit 410 for dispensing, such as Figures 1 to 3 shown.

[0039] To prevent the probe 310 and the catheter 410 from being damaged or deformed during the clamping process, in the present embodiment, the first chuck 300 and the second chuck 400 are both flexible chucks. The flexible chuck described in the present invention refers to a clamp that can be deformed when subjected to force and return to its original shape after the external force is removed. After the force is applied, the first chuck 300 fits against the outer peripheral surface of the probe 310, and the second chuck 400 fits against the outer peripheral surface of the catheter 410. Both the first chuck 300 and the second chuck 400 fit against the outer peripheral surface of the workpiece to be clamped to provide a stable clamping force. After the external force is removed, the chuck returns to its original shape to release the workpiece. The chuck has the characteristics of strong adaptability, easy operation, and no damage to the workpiece.

[0040] The encapsulation of the sensing window 320 of the probe 310 is performed by glue dispensing on a horizontal plane, and the joint between the rear end of the probe 310 and the catheter 410 needs to be subjected to rotary ring coating. The glue used in the two places is different, and the glue dispensing methods adopted are different. In this embodiment, the glue dispensing assembly 200 can be provided with two groups, one of which is used for the glue coating encapsulation of the sensing window 320 of the probe 310, and the other group is used for the rotary ring coating at the joint between the probe 310 and the catheter 410. It can also be provided as a double-headed glue dispensing assembly containing two glue heads, and the two glue heads are respectively filled with glue for the sensing window 320 of the probe 310 and glue for encapsulation at the joint between the probe 310 and the catheter 410. The positions of the two glue heads are switched by rotating or moving so as to realize that the two glue heads are respectively aligned with the sensing window 320 of the probe 310 and the joint between the probe 310 and the catheter 410.

[0041] In order to realize the rotating ring coating at the joint of the probe 310 and the catheter 410, the present embodiment can synchronously rotate the first chuck 300 and the second chuck 400 while keeping the position of the glue dispensing component 200 unchanged, or keep the position of the first chuck 300 and the second chuck 400 unchanged and rotate the glue dispensing component 200 that has been aligned with the joint of the probe 310 and the catheter 410. When the present embodiment adopts two groups of glue dispensing components 200, if the two groups of glue dispensing components 200 are independent of each other, the glue dispensing at the sensing window 320 of the probe 310 and the joint of the probe 310 and the catheter 410 can be carried out synchronously. Specifically, the glue dispensing component 200 corresponding to the sensing window 320 of the control probe 310 remains stationary, and the glue dispensing component 200 corresponding to the joint of the control probe 310 and the catheter 410 is rotated.

[0042] In order to avoid the problems of high equipment cost, large equipment size and mutual interference between moving parts caused by rotating the dispensing component 200, in this embodiment, when dispensing glue at the connection between the probe 310 and the catheter 410, the probe 310 and the catheter 410 rotate synchronously, while the position of the dispensing component 200 remains unchanged.

[0043] Specifically, the first chuck 300 is rotatably mounted on the first mounting frame 500, and the second chuck 400 is rotatably mounted on the second mounting frame 600. The first chuck 300 and the second chuck 400 rotate synchronously. Figure 4 There are many ways to control the synchronous rotation of the first chuck 300 and the second chuck 400, such as dual motor control, such as a single motor connected to a transmission mechanism with two output ends to achieve synchronization; such as through the linear reciprocating motion of the cylinder or the oil cylinder, the linear reciprocating motion is converted into rotation through a transmission mechanism that converts linear motion into rotation, and the transmission mechanism can be a transmission mechanism with two output ends, and the two output ends are respectively connected to the first chuck 300 and the second chuck 400.

[0044] The specific implementation steps of this embodiment are as follows:

[0045] The first clamp 300 is used to clamp the probe 310, and the second clamp 400 is used to clamp the catheter 410. The first clamp 300 and the second clamp 400 are arranged to realize the assembly of the probe 310 and the catheter 410. The dispensing assembly 200 is arranged to dispense glue at the sensing window 320 of the probe 310 and the joint between the probe 310 and the catheter 410. When dispensing glue at the joint between the probe 310 and the catheter 410, the first clamp 300 and the second clamp 400 rotate synchronously, and the automatic spin coating at the joint between the probe 310 and the catheter 410 can be realized, thereby meeting the precision requirements of the micro pressure sensor bougie packaging.

[0046] Embodiment 2

[0047] This embodiment is a second embodiment of an integrated dispensing assembly device. This embodiment is similar to the first embodiment, except that the first chuck 300 is connected to a first motor 510, the second chuck 400 is connected to a second motor 620, the first motor 510 and the second motor 620 are both servo motors, and the first motor 510 and the second motor 620 rotate synchronously. Figure 4 The dual-motor synchronous control method can not only retain the movement flexibility of the probe 310 and the catheter 410, but also ensure that during the spin coating process after the assembly, the probe 310 and the catheter 410 can be highly consistent in parameters such as speed, position and torque, and achieve synchronous rotation, thereby achieving automatic spin coating at the joint between the probe 310 and the catheter 410.

[0048] The synchronously rotating object probe 310 and catheter 410 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.

[0049] Specifically, in this embodiment, the tail of the first chuck 300 is a rotating shaft 330, the first motor 510 is mounted on the first mounting frame 500, and the output shaft of the first motor 510 passes through the first mounting frame 500 and is connected to the rotating shaft 330. In order to ensure the coaxial and stable connection between the rotating shaft 330 and the output shaft of the first motor 510, a coupling 511 is connected between the rotating shaft 330 and the output shaft of the first motor 510 in this embodiment, such as Figure 4As shown. The tail of the second chuck 400 is a clamping rod 420. Since the conduit 410 passing through the clamping rod 420 is easy to deform and bend, the length of the clamping rod 420 needs to be set long enough to avoid the deflection of the conduit 410 during the centering process. Otherwise, the second motor 620 cannot be directly installed on the second mounting frame 600. Therefore, in this embodiment, the second mounting frame 600 is a bearing seat, and the clamping rod 420 passes through the bearing seat, and a transmission structure is connected between the clamping rod 420 and the second motor 620. Specifically, the transmission structure of this embodiment is a belt transmission structure, and a driven pulley 610 is connected to the outer periphery of the clamping rod 420. The second motor 620 is installed on the first motion platform 700. The output shaft of the second motor 620 is connected to a driving pulley 630. The driving pulley 630 and the driven pulley 610 are transmitted by a belt 640, as shown in FIG. Figure 5 In addition to the belt 640 transmission, other transmission structures such as chain transmission, gear transmission, etc. can also be applied to the present invention.

[0050] In order to avoid the deflection of the catheter 410 caused by the pulling effect of the driven pulley 610 and the belt 640, the driven pulley 610 of this embodiment can be rotatably mounted on the second mounting frame 600. In order to facilitate the installation and connection operation, the first mounting frame 500 and the second mounting frame 600 in this embodiment are both L-shaped structures. The first motor 510 and the second motor 620 are both servo motors, and the high-precision and high-stability coordinated movement between the two is achieved through the master-slave synchronous control function mode; this dual-motor synchronous control method can not only retain the movement flexibility of the components, but also ensure that the probe 310 and the catheter 410 after assembly can be highly consistent in parameters such as speed, position and torque, thereby achieving synchronous rotation.

[0051] The specific implementation steps of this embodiment are similar to those of the first embodiment, except that:

[0052] The probe 310 is driven to rotate by the first motor 510, and the catheter 410 is driven to rotate by the second motor 620. Both the first motor 510 and the second motor 620 are servo motors. The master-slave synchronous control function mode is used to achieve high-precision and high-stability coordinated movement between the two. This dual-motor synchronous control method can not only retain the movement flexibility of the components, but also ensure that the probe 310 and the catheter 410 after assembly can be highly consistent in parameters such as speed, position and torque, and achieve synchronous rotation, so that the probe 310 and the catheter 410 can be automatically spin-coated at the joint while the probe 310 and the catheter 410 remain relatively still, thereby improving the accuracy of packaging and the precision of the product.

[0053] Embodiment 3

[0054] This embodiment is the third embodiment of the integrated glue dispensing assembly device. This embodiment is similar to the first embodiment or the second embodiment, except that the glue dispensing assembly 200 is a rotary double-head glue dispensing assembly.

[0055] like Figure 6 As shown, the dispensing assembly 200 includes a mounting plate 210, a first glue head 220 and a second glue head 230 mounted on the front of the mounting plate 210, and a rotary cylinder 240 mounted on the back of the mounting plate 210, and the rotary cylinder 240 is mounted on the output end of the lifting assembly 900. By controlling the rotary cylinder 240 to rotate and change the positions of the first glue head 220 and the second glue head 230, the dispensing assembly 200 can be effectively prevented from interfering with and colliding with other components during the dispensing process, and the design of this rotary double-head dispensing mechanism can reduce the volume of the tooling.

[0056] The first glue head 220 is mounted on the first fixing block 250, and the second glue head 230 is mounted on the second fixing block 260. The first fixing block 250 and the second fixing block 260 are both arranged vertically with respect to the mounting plate 210. The first glue head 220 includes a first syringe and a first needle which are connected to each other, and the second glue head 230 includes a second syringe and a second needle which are connected to each other. The first syringe can be fixedly mounted on the first fixing block 250 by screws, and the second syringe can also be fixedly mounted on the second fixing block 260 by screws. Figure 6 shown.

[0057] In this embodiment, the axis of the first glue head 220 is perpendicular to the axis of the second glue head 230. The axes of the first glue head 220 and the second glue head 230 are arranged vertically, which reduces the volume occupied by the glue dispensing component 200 while satisfying the rotation switching. In order to avoid the mounting plate 210 from colliding with other components during the rotation process, the mounting plate 210 in this embodiment is similar to a parallelogram structure, and the edges on both sides are processed with arc surfaces. In this embodiment, the positions of the first glue head 220 and the second glue head 230 before and after the rotation switching can be located at the same position. At this time, the glue dispensing position before and after the rotation switching can also be changed by setting the fourth motion platform 140; after the rotation switching of this embodiment, the first glue head 220 and the second glue head 230 can also just correspond to the position of the sensing window 320 and the joint between the catheter 410 and the probe 310.

[0058] The specific implementation steps of this embodiment are similar to those of Embodiment 1 or Embodiment 2, except that:

[0059] The first syringe contains the packaging material of the sensing window 320, and the second syringe contains the packaging material at the joint between the catheter 410 and the probe 310; when the sensing window 320 needs to be packaged first, the position of the first syringe and the first needle is adjusted by the lifting assembly 900 and the fourth motion platform 140 so that the first needle is aligned with the sensing window 320, and the packaging material in the first syringe is pushed out to complete the packaging of the sensing window 320. Figure 2 As shown; after packaging the butt joint of the catheter 410 and the probe 310, the positions of the second syringe and the second needle are adjusted by the lifting assembly 900 and the fourth motion platform 140, so that the second needle is aligned with the butt joint position of the catheter 410 and the probe 310, and the packaging material in the second syringe is pushed out. At the same time, the probe 310 and the catheter 410 are controlled to rotate synchronously by the first motor 510 and the second motor 620 to complete the spin coating at the butt joint of the catheter 410 and the probe 310, as shown. Figure 3 shown.

[0060] Embodiment 4

[0061] The present embodiment is the fourth embodiment of the integrated assembly and dispensing device, and the present embodiment is similar to the first to third embodiments, except that, in order to realize the centering assembly of the probe 310 and the catheter 410, the first chuck 300 and / or the second chuck 400 in the present embodiment can be displaced and adjusted in at least one of the three directions of XYZ, wherein the axial direction of the probe 310 and the catheter 410 is the X direction.

[0062] In order to realize the centering of the probe 310 and the catheter 410, at least one of the first chuck 300 and the second chuck 400 needs to move, so at least one of the first mounting frame 500 and the second mounting frame 600 is installed on the first motion platform 700. When one of the first mounting frame 500 and the second mounting frame 600 is installed on the first motion platform 700, and the other of the first mounting frame 500 and the second mounting frame 600 is fixedly installed on the bottom plate 150, the positions of the probe 310 and the catheter 410 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 respectively installed on different first motion platforms 700, the positions of the probe 310 and the catheter 410 can both move, which can improve the centering accuracy.

[0063] In this embodiment, the assembly and dispensing integrated device further includes a first motion platform 700, one of the first mounting frame 500 and the second mounting frame 600 is mounted on the first motion platform 700, the first motion platform 700 is mounted on the bottom plate 150, and the other of the first mounting frame 500 and the second mounting frame 600 is mounted on the first motion platform 700 or the bottom plate 150. Figure 4The bottom plate 150 may be a square plate, which mainly serves to integrate and arrange the first clamp 300, the second clamp 400, the first mounting frame 500, the second mounting frame 600 and the first motion platform 700.

[0064] This embodiment is described by taking the second chuck 400 mounted on the second mounting frame 600, the second mounting frame 600 mounted on the first motion platform 700, and the first chuck 300 fixedly mounted on the bottom plate 150 as an example. For ease of description, this embodiment places the assembly dispensing integrated device in an XYZ three-dimensional coordinate system, and the axial direction of the probe 310 and the catheter 410 is the X direction.

[0065] In this embodiment, the first motion platform 700 can be a single-degree-of-freedom adjustment platform, one of the first mounting frame 500 and the second mounting frame 600 is installed on the first motion platform 700, and the motion direction of the first motion platform 700 is the axial direction of the probe 310 and the catheter 410. In this way, the catheter 410 and the probe 310 can be close to each other; the centering of the probe 310 and the catheter 410 can be achieved by assembling the first chuck 300 and the second chuck 400. During the assembly process, there is no need to adjust the centering of the catheter 410 and the probe 310 in directions other than the axial direction, which is easy to operate. The single-degree-of-freedom platform of this embodiment can be specifically a linear module or a single-degree-of-freedom motion structure similar to a linear module. The first motion platform 700 can also be an XY dual-degree-of-freedom motion platform, which can realize the centering assembly of the probe 310 and the catheter 410 in the three directions of XYZ in conjunction with the height adjustment setting of the third motion platform 800; the XY dual-degree-of-freedom motion platform can be specifically a motion structure composed of two linear modules.

[0066] The alignment of the probe 310 and the catheter 410 in the Z direction is achieved through the third motion platform 800, so as to avoid the misalignment in the height direction when the first chuck 300 and the second chuck 400 clamp probes 310 and catheters 410 of different sizes. In this embodiment, the third motion platform 800 is installed on the first motion platform 700, and the movement direction of the third motion platform 800 is the height direction perpendicular to the axial direction of the probe 310 and the catheter 410, that is, the Z direction. The third motion platform 800 realizes the height adjustment of the catheter 410, thereby realizing the alignment of the two devices, the catheter 410 and the probe 310, in the height position.

[0067] In this embodiment, the third motion platform 800 includes a fixed block 810 and an inclined groove 820 fixedly mounted on the first motion platform 700, an adjusting member 830 rotatably mounted on the fixed block 810, and an inclined slider 840 provided on the second mounting frame 600. One end of the adjusting member 830 abuts against the inclined slider 840, and the inclined slider 840 is slidably connected with the inclined groove 820. The slidable connection between the inclined slider 840 and the inclined groove 820 is actually to smoothly, efficiently and accurately convert the horizontal movement of the adjusting member 830 into the movement in the height direction of the second chuck 400 through the cooperation of an inclined surface provided on the inclined slider 840 and an inclined surface located in the inclined groove 820. Figure 5 As shown. In this embodiment, the horizontal movement of the adjusting member 830 is converted into movement in the height direction by the inclined surface cooperation between the inclined sliding block 840 and the inclined groove 820. 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 sliding block 840 and the inclined groove 820, in this embodiment, limit blocks are arranged on both sides of the inclined sliding block 840, and limit grooves slidably connected to the limit blocks are arranged on both sides of the inclined groove 820. The arrangement of the limit grooves and the limit blocks can effectively prevent the inclined sliding block 840 from sliding off the inclined groove 820.

[0068] The specific implementation steps of this embodiment are similar to those of Embodiments 1 to 3, except that:

[0069] The first motion platform 700 is installed on the base plate 150, and is used to drive the third motion platform 800 and all the components thereon to move along the X direction; the third motion platform 800 is installed on the first motion platform 700, and is used to drive the second chuck 400 and the catheter 410 clamped thereon to move along the Z direction; after the catheter 410 and the probe 310 are clamped, the height of the second chuck 400 and the catheter 410 clamped thereon are adjusted by the third motion platform 800 so that the catheter 410 and the probe 310 are centered; after the centering is completed, the third motion platform 800 and all the components thereon are driven to move along the X direction by controlling the first motion platform 700 until the catheter 410 is extended into a specific position in the probe 310.

When this embodiment is implemented, the lifting and lowering of the dispensing component 200 can be achieved by the forward and reverse rotation of the lifting motor 910. In addition, it should be noted that in this embodiment, other transmission mechanisms such as linear modules, gear racks, worm gears, etc. that can convert motor rotation into up and down linear motion of the dispensing component 200 can be applied to the present invention.

[0076] Specifically, the second motion platform 130 includes a linear slide rail 131 installed on the horizontal mounting platform 110, a slider 132 installed at the bottom of the base plate 150, and a driving device 133 for driving the slider 132 to slide linearly along the linear slide rail 131. The driving device 133 is specifically a transmission belt structure, and the slider 132 is connected to the transmission belt. Figure 7 As shown. In order to ensure the overall beauty and simplicity of the device, the linear guide rail 131, the driving device 133, and the slider 132 are partially hidden in the box in this embodiment. Of course, it should be noted that in addition to the above structure, the second motion platform 130 can also use other drive transmission mechanisms that can realize the linear motion of the bottom plate 150 along the Y direction. The structure of the fourth motion platform 140 can be consistent with that of the second motion platform 130, and other drive transmission mechanisms that can realize the linear motion of the lifting component 900 along the X direction can also be used.

[0077] The specific implementation steps of this embodiment are similar to those of the fourth embodiment, except that:

[0078] The base plate 150 is installed at the output end of the second motion platform 130.

[0079] Embodiment 6

[0080] This embodiment is the sixth embodiment of the integrated assembly and dispensing device. This embodiment is similar to the first to fifth embodiments, except that, in this embodiment: the first clamp 300 and the first tension adjustment member 340 cooperate to achieve flexible clamping of the probe 310.

The first clamping portion 360 and the second clamping portion 370 are both connected to the first connecting portion 350 and are located on the same side of the first connecting portion 350. A first deformation groove 380 that is interconnected and a first positioning portion 390 for accommodating the probe 310 are provided between the first clamping portion 360 and the second clamping portion 370. The first deformation groove 380 is tightened by the first tension adjusting member 340 to achieve flexible clamping of the probe 310. Figure 8As shown. In this embodiment, the first deformation groove 380 is a small gap, located below the first positioning portion 390 or below the first positioning portion 390 and close to the side of the first connecting portion 350, 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 390 are merged together, which can prevent the clamping force from continuing to act on the probe 310, further protecting the probe 310 from damage, and better achieving flexible clamping of the probe. The first deformation groove 380 separates the first clamping portion 360 and the second clamping portion 370, which can reduce the use of other components, effectively reduce the overall volume space, and greatly reduce the complexity of the tooling.
