Description

Technical Field

[0001] The utility model relates to the technical field of medical device production equipment, in particular to a device for assembling a precision filter and a short catheter. Background Art

[0002] Infusion sets are commonly used auxiliary devices in medical treatment, mainly used for intravenous infusion. They are important disposable medical consumables that have been sterilized to establish a channel between the vein and the liquid medicine. When producing and assembling infusion sets, it is necessary to assemble the precision filter and the catheter.

[0003] At present, there are some devices for assembling precision filters with conduits. For example, Chinese patent ZL202223319585.2 discloses an automatic assembly device for precision filters, including a feeding mechanism, a material positioning mechanism, an assembly mechanism, and a transfer mechanism, etc. However, the precision filters targeted by the automatic assembly device usually do not have exhaust holes, and the liquid inlet and outlet pipes of the precision filter in the assembled finished product are in a horizontal state, and the circular main body is in an upright state for subsequent transfer and transmission. However, for precision filters with exhaust holes in the circular main body, the assembled product needs to be tested for air tightness later. Therefore, it is best to make the liquid inlet and outlet pipes of the precision filter in the assembled product in a horizontal state, and the circular main body is also in a horizontal state for transfer and transmission, so as to facilitate the subsequent air tightness test. Therefore, it is necessary to design a device that meets the requirements for assembling precision filters with short conduits. Utility Model Content

[0025] The transfer mechanism 7 is used to transfer the assembled precision filter 1 and the short conduit; it is located below the material taking assembly mechanism 5 and adjacent to the conduit clamping mechanism 6.

[0026] Among them, the specific structures of the assembly mechanism and the transfer mechanism 7 can adopt known structures in the prior art, such as the assembly mechanism and transfer mechanism involved in an automatic assembly device for a precision filter disclosed in Chinese patent ZL202223319585.2, which are not the focus of protection of this patent application.

[0027] The specific structure of the feeding mechanism 2 is similar to the feeding mechanism in the prior art, except that it includes N material channels 201, N is a positive integer, the liquid inlet pipe and the liquid outlet pipe of each precision filter 1 in each material channel 201 are in a horizontal state, and the circular main body is also in a horizontal state, and a pressure plate 202 is provided between two adjacent material channels 201 to prevent the precision filter 1 from detaching from the material channel 201.

[0028] The structure of the material receiving mechanism 3 is as follows: it includes a base plate 301, and the base plate 301 is fixed at a first preset position. In this embodiment, the base plate 301 is fixed on the supporting base plate of the supporting frame 9, and the assembling mechanism and the transfer mechanism 7 are also assembled on the supporting frame 9. A first slide rail 302 is provided on the bottom plate 301 along the front-to-back direction, and a first slider 303 used in conjunction with the first slide rail 302 is fixed on the lower surface of the sliding bottom plate 304. The sliding bottom plate 304 can slide forward and backward along the first slide rail 302 under the action of a first cylinder 305. The first cylinder 305 is assembled on a cylinder seat plate 306, and the cylinder seat plate 306 is fixed on the bottom plate 301. A limiting mechanism 307 for limiting the moving stroke of the sliding bottom plate 304 is also provided on the bottom plate 301. The limiting mechanism 307 may include a limiting plate and a limiting top screw arranged on the limiting plate; two first vertical plates 308 are provided opposite to each other on the upper surface of the sliding bottom plate 304, and a first mounting plate 309 is connected to the top ends of the two first vertical plates 308. A second slide rail 3014 is provided on the first mounting plate 309 along the left-right direction, and a first slider 303 used in conjunction with the second slide rail 3014 is provided on the first mounting plate 309. The two sliders 3013 are fixed on the lower surface of the first adapter plate 3012, and the first adapter plate 3012 is fixedly connected to the adapter block 3011, and the adapter block 3011 is connected to the second cylinder 3010 arranged on the upper surface of the first mounting plate 309. When the second cylinder 3010 is driven to operate, the first adapter plate 3012 slides along the left and right directions. A limiting mechanism 3015 is also provided on the upper surface of the first mounting plate 309 for limiting the moving stroke of the first adapter plate 3012. A receiving plate 3017 is connected to the upper surface of the first adapter plate 3012 via a support plate 3016. The receiving plate 3017 is arranged along the left and right directions, and 2N receiving grooves 3018 are arranged at intervals on the receiving plate 3017. A baffle 3019 is provided on the end of the receiving plate 3017 away from the feeding mechanism 2 for preventing the precision filter 1 transported to the receiving groove 3018 from falling. The material receiving mechanism 3 can receive two groups of precision filters 1 from the feeding mechanism 2 .

[0029] In this embodiment, the device for assembling the precision filter with the short duct further includes a material blocking mechanism 4, which is used to block the precision filter 1 in the feeding mechanism 2 when necessary. Specifically, after a group (N) of precision filters 1 in the feeding mechanism 2 are correspondingly conveyed to the N receiving grooves 3018 on the receiving plate 3017, the precision filter 1 in the feeding mechanism 2 is blocked by the material blocking mechanism 4, so that the receiving plate 3017 in the receiving mechanism 3 slides along the left and right directions, so that the other N receiving grooves 3018 on the receiving plate 3017 are aligned with the feeding mechanism 2. In addition, the process of the material picking assembly mechanism 5 grabbing the precision filter 1 on the receiving mechanism 3 also requires the precision filter 1 in the feeding mechanism 2 to be blocked by the material blocking mechanism 4.

[0030] The structure of the material blocking mechanism 4 is as follows: it includes a top plate 401, and the top plate 401 is fixed at a second preset position. In the present embodiment, the top plate 401 is fixed at the lower surface of the supporting top plate of the supporting frame 9, and two second vertical plates 402 are relatively arranged on the lower surface of the top plate 401, and a second mounting plate 403 is connected between the two second vertical plates 402, and a third cylinder 404 is mounted on the second mounting plate 403, and the third cylinder 404 can drive the lifting plate 405 to perform lifting movement, and two lifting guide shafts 406 are spaced apart on the lifting plate 405, and the two lifting guide shafts 406 are disposed on the left and right sides of the third cylinder 404, and two linear bearings 407 used in conjunction with the two lifting guide shafts 406 are mounted on the second mounting plate 403; a limiting mechanism can also be provided on the second mounting plate 403 to limit the moving stroke of the lifting plate 405, and specifically, the limiting mechanism can adopt a limiting top screw. The lifting plate 405 is connected with a material separator plate 409 via a second adapter plate 408. When the lifting plate 405 is lowered, the material separator plate 409 blocks the end of the feeding mechanism 2 to block the precision filter 1 in the feeding mechanism 2. In order to allow the precision filter 1 to be neatly transported forward and smoothly enter the receiving slot 3018 on the receiving plate 3017, N material separator holes 4010 are arranged at intervals on the material separator plate 409, and a receiving hole 4011 is arranged at the material separator plate 409 between two adjacent material separator holes 4010. When the lifting plate 405 is lowered, each material separator hole 4010 corresponds to each material channel 201 one by one, and the front end of the precision filter 1 passes through the corresponding material separator hole 4010, but the circular main body of the precision filter 1 is blocked by the material separator hole 4010, and the receiving hole 4011 cooperates with the pressing plate 202 between two adjacent material channels 201.

[0031] The device for assembling the precision filter and the short duct involved in the present application also includes a static visual inspection mechanism 8, which is used to detect whether the assembled product transported on the transfer mechanism 7 is assembled properly, so as to facilitate the removal of waste products in subsequent processes. In this embodiment, the static visual inspection mechanism 8 is assembled at a preset position, such as on the support frame 9, and the static visual inspection mechanism 8 includes a first assembly seat 801, the first assembly seat 801 is assembled at a third preset position, a light source 802 is provided on the first assembly seat 801, and a camera used in conjunction with the light source 802 is arranged on a second assembly seat 803, the second assembly seat 803 is arranged at a fourth preset position, and a lens 804 is provided on the camera.

[0032] In the specific use process, the precision filter 1 is transported by the feeding mechanism 2, and the liquid inlet pipe and the liquid outlet pipe of the precision filter 1 are in a horizontal state, and the circular main body is also in a horizontal state for transportation; when a group of precision filters 1 in the feeding mechanism 2 are correspondingly transported to the N receiving grooves 3018 on the receiving plate 3017, the precision filters 1 in the feeding mechanism 2 are blocked by the blocking mechanism 4, so that the receiving plate 3017 in the receiving mechanism 3 slides along the left and right directions, so that the other N receiving grooves on the receiving plate 3017 The material trough 3018 is aligned with the feeding mechanism 2, and then the lifting plate 405 is driven to rise, so that another group of precision filters 1 in the feeding mechanism 2 are correspondingly transported to the other N material receiving troughs 3018 on the receiving plate 3017, and then the first cylinder 305 is driven to operate, so that the sliding bottom plate 304 moves forward, and the precision filter 1 on the receiving mechanism 3 is grabbed by the material picking assembly mechanism 5, and then assembled with the short tube on the tube clamping mechanism 6; the assembled precision filter 1 and the short tube are transferred by the transfer mechanism 7.

[0033] The device for assembling a precision filter with a short tube involved in the present application has a compact structure and a reasonable design. In the assembled product, the liquid inlet pipe and the liquid outlet pipe of the precision filter are in a horizontal state, and the circular main body is also in a horizontal state for transfer and transmission. For the precision filter with an exhaust hole in the circular main body, the subsequent air tightness test can be facilitated. The device can also be adapted to the assembly of the precision filter with no exhaust hole in the circular main body.

[0034] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
