[0002] With the continuous development of society and the continuous progress of the medical industry, intravenous infusion has become the most common treatment method in daily treatment. When performing intravenous infusion, drugs need to be input into the human body through an infusion set. Therefore, the infusion set has become the most important tool for intravenous infusion.

[0003] An infusion set usually includes a spike, a precision filter, a tube, a drip chamber, a flow regulator, an intravenous infusion needle, etc. Currently, in the drip chamber, the impact generated when the dripping liquid medicine contacts the liquid surface will produce bubbles. These bubbles are very likely to enter the human body along with the liquid medicine, posing a certain safety hazard. Therefore, there is an urgent need for a production line to assemble and produce an anti-foam drip chamber. The anti-foam drip chamber includes a drip chamber body, a two-way tube, a drip chamber cap, and a flow diverter umbrella, which can effectively eliminate the bubbles generated in the drip chamber and prevent hazards such as air embolism.

[0004] In the production line of the anti-foam drip chamber, it is necessary to design a mechanism for assembling a two-way tube and a drip chamber body after gluing, so as to assemble the two-way tube and the drip chamber body together for the subsequent assembly and production of the anti-foam drip chamber.

Detailed implementation manners

[0034] The following further describes the specific embodiments of the present application with reference to the accompanying drawings.

[0035] In the description of the present application, it should be understood that terms such as "first", "second", etc. are used to distinguish similar objects, rather than to describe or indicate a specific order or sequence. Terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0036] As Figures 1 to 13 shown, the mechanism for assembling the two-way pipe and the glue-coated drip hopper body involved in the present application includes a feeding unit 1, a receiving and blocking unit 3, a picking, flipping and assembling unit 4, and a positioning and guiding unit 5. Among them, the feeding unit 1 is used to feed the two-way pipe A02 into the receiving and blocking unit 3. The receiving and blocking unit 3 is used to receive the current group (for example, N, N is a positive integer) of two-way pipes A02 from the feeding unit 1 and can stop the next group of two-way pipes A02 in the feeding unit 1. At this time, the two-way pipes A02 are in an upright state. The picking, flipping and assembling unit 4 is used to obtain the two-way pipes A02 on the receiving and blocking unit 3, and can flip the two-way pipes A02 by 90°, making them in a horizontal state, and can assemble the flipped two-way pipes A02 with the glue-coated drip hopper body A01. During the process of the picking, flipping and assembling unit 4 assembling the flipped two-way pipes A02 with the glue-coated drip hopper body A01, the two-way pipes A02 are positionally guided by the positioning and guiding unit 5 so that they can be smoothly assembled with the glue-coated drip hopper body A01. Specifically, the glue-coated drip hopper body A01 is clamped and fixed by a relevant clamping mechanism, which is not the focus of protection of the present application and will not be described in detail in terms of structure. For example, the glue-coated drip hopper body A01 can be clamped and fixed in the storage tool 9, and the storage tool 9 is arranged on the turntable 8. The turntable 8 is driven to rotate by a driving mechanism (such as a cam box 7) arranged on the workbench 6. When it rotates to a preset position, it stops rotating, and the assembly of the two-way pipe A02 and the glue-coated drip hopper body A01 is realized through the mechanism for assembling the two-way pipe and the glue-coated drip hopper body involved in the present application.

[0037] In this embodiment, the structure of the feeding unit 1 is as follows: It includes a lower bottom plate 101, on which a linear vibration bottom plate 102 is provided. On the linear vibration bottom plate 102, a linear vibrator 103 is provided. On the linear vibrator 103, a channel fixing plate 104 is provided. Along the left-right direction, N linear channels 105 are provided at intervals on the channel fixing plate 104. The value of N is the same as the number of drip chamber bodies to be assembled. Each linear channel 105 is arranged along the front-back direction. The shape of the linear channel 105 is set according to requirements. In this embodiment, the cross-section of the linear channel 105 is U-shaped, so that the two-way pipe A02 can be transported upright from back to front. On the linear channel 105, a channel pressing plate 106 is provided to prevent the two-way pipe A02 from deviating from the linear channel 105. Specifically, two channel pressing plates 106 are provided on each linear channel 105 for cooperation. At the rear end of the channel pressing plate 106, a material shortage detection mechanism 107 is further provided for detecting whether there is a shortage of materials in the corresponding linear channel 105. Specifically, the material shortage detection mechanism 107 includes a detection bracket provided on the channel pressing plate 106 and a detection optical fiber provided on the detection bracket. The detection optical fiber is connected to the control unit.

[0038] The mechanism for assembling the two-way pipe and the drip chamber body after gluing further includes a support frame 2. The support frame 2 includes a support bottom plate 201, two support vertical plates 202 oppositely arranged on the support bottom plate 201, and a support top plate 203 connected to the upper ends of the two support vertical plates 202. The support top plate 203 is in a shape of a Chinese character 'hui', that is, the middle part of the support top plate 203 is hollow. The material receiving and blocking unit 3, the material taking, flipping and assembling unit 4, and the centering and guiding unit 5 are all arranged on the support frame 1. Of course, the feeding unit 1 can also be arranged on the support bottom plate 201.

[0039] The structure of the material receiving and blocking unit 3 is as follows: It includes a first bottom plate 301 arranged on the support bottom plate 201. On the first bottom plate 301, two first vertical plates 302 are arranged opposite to each other left and right. A first mounting plate 303 is connected between the two first vertical plates 302. On the upper surface of the first mounting plate 303, a first cylinder 304 is provided. The first cylinder 304 is connected to a connecting plate 306 through a first floating joint 305. The connecting plate 306 is fixedly connected to a first sliding plate 307. On the lower surface of the first sliding plate 307, a first slider 308 is provided. A first slide rail 309 used in cooperation with the first slider 308 is fixed on the upper surface of the first mounting plate 303. On the upper surface of the first mounting plate 303, a limiting mechanism is also provided to limit the moving stroke of the connecting plate 306 in the left - right direction. In this embodiment, the limiting mechanism includes a limiting set - screw seat plate 3010 fixed on the upper surface of the first mounting plate 303 and a limiting set - screw 3011 arranged on the limiting set - screw seat plate 3010; On the upper surface of the first sliding plate 307, a material receiving and blocking seat plate 3012 is also fixedly connected. Along the left - right direction, N material receiving and blocking tires 3013 are arranged at intervals on the material receiving and blocking seat plate 3012. Each material receiving and blocking tire 3013 is provided with a material receiving groove 3014. On the material receiving and blocking tires 3013 on both the left and right sides of the material receiving groove 3014, optical fiber installation holes 3015 are respectively provided. The optical fiber installation holes 3015 are communicated with the material receiving groove 3014. At each optical fiber installation hole 3015, a transmissive detection optical fiber is installed to detect whether the two - way pipe A02 reaches the material receiving groove 3014. On the rear end surfaces of the material receiving and blocking tires 3013 on both the left and right sides of the material receiving groove 3014, a material blocking plane 3016 is formed. When the two - way pipe A02 reaches the material receiving groove 3014, under the action of the first cylinder 304, the material receiving and blocking tire 3013 moves to the right, making the material receiving groove 3014 misaligned with the linear material path 105. At this time, the two - way pipe A02 at the material receiving groove 3014 corresponds to the gaps between the two linear material paths 105, so as to facilitate the material taking and flipping and assembling unit 4 to take the material. The next group of two - way pipes A02 is stopped in the feeding unit 1 through the material blocking plane 3016.

[0040] To prevent the two - way pipe A02 at the material receiving groove 3014 from tilting forward and affecting the material taking of the material taking and flipping and assembling unit 4, in the feeding unit 1, it includes N material blocking plates 108. Each material blocking plate 108 is connected to the front end of the corresponding material path pressing plate 106, and each material blocking plate 108 is located at the left end of the corresponding linear material path 105. The material blocking plate 108 is in an L - shape, that is, it includes a long side part and a short side part that are perpendicular to each other. The long side part is connected to the material path pressing plate 106, and the short side part is connected to the right side of the long side part, and the short side part is located near the material receiving groove 3014 (for example, above the front of the material receiving groove 3014) to prevent the two - way pipe A02 fed to the material receiving groove 3014 from tilting forward.

[0041] The structure of the material taking, flipping and assembling unit 4 is as follows: It includes two second slide rails 401 arranged oppositely left and right on the support top plate 203.

The second air cylinder 405 is assembled on a first air cylinder mounting plate 406, and the first air cylinder mounting plate 406 is fixed on the support top plate 203. When the second air cylinder 405 is driven to act, the second slide plate 403 can move along the front-back direction. In order to limit the stroke of the front-back movement of the second slide plate 403, a limiting mechanism is provided on the support top plate 203. For example, a first limiting mechanism 407 and a second limiting mechanism 408 are provided on the support top plate 203. The first limiting mechanism 407 is used to limit the forward movement stroke of the second slide plate 403, and the second limiting mechanism 408 is used to limit the backward movement stroke of the second slide plate 403. Specifically, both the first limiting mechanism 407 and the second limiting mechanism 408 include an assembly plate and a buffer provided on the assembly plate.

[0045] The structure of the positive positioning guiding unit 5 is as follows: It includes an upper positive positioning guiding part and a lower positive positioning guiding part that cooperate with each other. When the two are butted together, they can clamp the drip hopper body after gluing and can play a positive positioning guiding role for the two-way pipe. The upper positive positioning guiding part includes two second vertical plates 501 that are relatively arranged on the front end of the lower surface of the support top plate 203. A third mounting plate 502 is connected between the two second vertical plates 501. A fifth cylinder 503 is assembled on the third mounting plate 502. The fifth cylinder 503 is connected to an upper seat plate 505 via a fourth floating joint 504. Under the action of the fifth cylinder 503, the upper seat plate 505 can perform a lifting motion. An upper positive positioning guiding plate 506 is provided on the lower surface of the upper seat plate 505. At the lower end surface of the upper positive positioning guiding plate 506, N upper positive positioning semi-holes 507 are provided at intervals. A positioning hole is provided on the upper positive positioning guiding plate 506 between two adjacent upper positive positioning semi-holes 507. Second guiding shafts 508 (such as two) are connected to the upper surface of the upper seat plate 505. The second guiding shafts 508 cooperate with second linear bearings 509 provided on the third mounting plate 502.

[0046] The lower positive positioning guide part includes a second base plate 5011 fixed on the support base plate 201. A lower positive positioning guide base plate 5012 is provided on the second base plate 5011. Two third vertical plates 5013 are provided on the lower positive positioning guide base plate 5012 in a left-right opposite manner. A fourth mounting plate 5014 is connected between the two third vertical plates 5013. A sixth air cylinder 5015 is assembled on the fourth mounting plate 5014. The sixth air cylinder 5015 is connected to a lifting connecting plate 5017 through a fifth floating joint 5016. Under the action of the sixth air cylinder 5015, the lifting connecting plate 5017 can perform lifting motion. A lifting slide plate 5018 is connected to the front end face of the lifting connecting plate 5017. A third sliding block 5019 is provided on the lifting slide plate 5018. A third slide rail 5020 used in cooperation with the third sliding block 5019 is arranged on a slide rail seat plate 5021 in the up-down direction. The slide rail seat plate 5021 is fixed between the two third vertical plates 5013. A lower positive positioning guide plate 5022 is further connected to the upper surface of the lifting connecting plate 5017. N lower positive positioning semi-holes 5023 are provided on the lower positive positioning guide plate 5022 at intervals in the left-right direction. Each of the lower positive positioning semi-holes 5023 is used in cooperation with each of the upper positive positioning semi-holes 507 for positive positioning of the two-way pipe A02 and can clamp the drip chamber body. A positioning pin 5024 is provided on the lower positive positioning guide plate 5022 between two adjacent lower positive positioning semi-holes 5023. The positioning pin 5024 is used in cooperation with a positioning hole so that the upper positive positioning part and the lower positive positioning part can be accurately positioned and butted together, and further each of the lower positive positioning semi-holes 5023 is used in cooperation with each of the upper positive positioning semi-holes 507. Specifically, the aperture of the complete positive positioning hole formed after the cooperation of the lower positive positioning semi-hole 5023 and the upper positive positioning semi-hole 507 is determined according to specific requirements. For example, along the direction from the rear to the front, the aperture gradually becomes smaller first to achieve the positive positioning effect on the two-way pipe, and then the aperture stepwise changes to the outer diameter size at the place where the drip chamber body needs to be clamped to clamp the drip chamber body.

[0047] In the specific use process, the two-way pipe A02 is fed into the material receiving and blocking unit 3 through the feeding unit 1. When it is detected that the two-way pipe A02 reaches the material receiving groove 3014, under the action of the first cylinder 304, the material receiving and blocking tire 3013 moves to the right, so that the material receiving groove 3014 is misaligned with the linear material path 105. At this time, the two-way pipe A02 at the material receiving groove 3014 corresponds to the gaps between the two linear material paths 105, so as to facilitate the material taking of the material taking, flipping and assembling unit 4. The next group of two-way pipes A02 is stopped in the feeding unit 1 through the blocking plane 3016. Then, the material taking, flipping and assembling unit 4 clamps the two-way pipe A02 at the material receiving groove 3014, and then controls the material taking claw 4031 to rise and flip 90°, so that the two-way pipe A02 is in a horizontal state. Then, control the material taking claw 4031 to move forward. During this process, the telescopic rod of the third cylinder 4010 is in the extended state, and the upper and lower positioning guiding parts are in the butt joint state to clamp the drip bucket body. As the material taking claw 4031 moves forward, the top cylinder head acts on the second sliding plate 403, which can apply resistance to the forward movement of the second sliding plate 403. During this period, the material taking claw 4031 moves forward slowly. The front end of the two-way pipe A02 is inserted into the glue-applied part of the drip bucket body by the cooperation of each lower positioning guiding half hole 5023 and each upper positioning guiding half hole 507 for the positive positioning guidance of each two-way pipe A02 (because the two-way pipe A02 clamped by the material taking claw 4031 may be a little crooked). Then, the upper and lower positioning guiding parts are separated, and the telescopic rod of the third cylinder 4010 retracts. Continue to control the material taking claw 4031 to move forward to complete the assembly of the two-way pipe A02 and the drip bucket body.

[0048] The mechanism for assembling the two-way pipe and the glue-applied drip bucket body involved in this application can quickly and efficiently assemble the two-way pipe and the drip bucket body, and the assembled product has a stable structure and high durability.

Any person skilled in the art within the technical scope disclosed in this application, according to the technical solution and its concept of this application, makes equivalent substitutions or changes, and should be covered by the protection scope of this application.
