[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] In related technologies, medical infusion sets are all for single use, and the market demand for them is huge. In the manufacturing of medical infusion sets, a conveyor line is used to transport the sets, ensuring a high degree of automation in production. To guarantee the product yield of medical infusion sets, defective sets are inspected on the conveyor line. Defective sets are unloaded from the line, and the line is replenished to ensure it is fully loaded. Currently, when replenishing empty spaces on the conveyor line, the position and orientation of the infusion sets are sometimes skewed or offset, making it difficult to place them directly into the empty spaces, resulting in low replenishment efficiency.

[0026] To solve the above problems, please refer to... Figure 1 As shown, an embodiment of this application provides a feeding device 100, which includes a transfer line 110, a material transfer line 120, and a material transfer mechanism 130.

[0027] refer to Figure 1 and Figure 2As shown, the feeding device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X is the length direction of the feeding device 100, the second direction Y is the width direction of the feeding device 100, and the third direction Z is the height direction of the feeding device 100. The conveying direction of the material conveying line 120 is the first direction X. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the feeding device 100 and should not be construed as limitations on this application.

[0028] Specifically, in combination Figure 1 and Figure 2 As shown, multiple first material stations 111 are sequentially arranged along the transfer line 110 in the first direction X, and multiple second material stations 121 are sequentially arranged along the material transfer line 120 in the first direction X. The first direction X is the transmission direction of the material transfer line 120. The first material stations 111 and the second material stations 121 are arranged parallel to each other. The material transfer mechanism 130 includes a moving platform 131 and a suction component 132. The suction component 132 is movably connected to the moving platform 131. The moving platform 131 is used to drive the suction component 132 to move along the second direction Y, so that the suction component 132 reciprocates between the transfer line 110 and the material transfer line 120. The material transfer line 120 is used to transfer materials in the production process for subsequent manufacturing and processing. The first material stations 111 arranged on the transfer line 110 are used to temporarily store materials waiting to be replenished.

[0029] In this embodiment, the material suction assembly 132 is provided with at least two suction elements 1321 along the first direction X. After the defective materials at multiple second material stations 121 of the material conveying line 120 are unloaded, the corresponding second material station 121 is in an empty state. The transfer conveying line 110 can then transport materials to facilitate material suction by the material suction assembly 132. At least two suction elements 1321 can simultaneously pick up multiple materials to be replenished at the first material station 111. Each suction element 1321 corresponds to one first material station 111 and is arranged along the second direction X. The Y-axis moves to the material conveyor line 120 to sequentially replenish the second material station 121 that is in a vacant state. The first material station 111 and the second material station 121 are set in parallel to ensure that the position and orientation of the material to be replenished are convenient for placement in the second material station 121. At least two suction components 1321 can selectively correspond to the vacant second material station 121, thereby improving the replenishment efficiency, keeping the material conveyor line 120 at full load, ensuring the material product yield of the material conveyor line 120, and thus improving production efficiency.

[0030] Of course, the number of suction components 1321 in the suction assembly 132 can be greater than two. For example, the number of suction components 1321 can be three, four, six or eight, and no specific limitation is made here.

[0031] For example, such as Figure 1 As shown, each first material station 111 is a material positioning slot. The size of the first material station 111 is the same as that of the second material station 121. Correspondingly, each second material station 121 is also a material positioning slot. Multiple material positioning slots are arranged along the first direction X. The distance between two adjacent material positioning slots is adapted to the distance between two suction components 1321, so that at least two suction components 1321 of the suction assembly 132 can simultaneously draw infusion set 200 material from the first material station 111.

[0032] In one embodiment, alternatively, referencing Figure 2 and Figure 3 As shown, the mobile platform 131 includes a first moving component 1312 and a second moving component 1313. A first slide rail 1312a is provided on one side of the first moving component 1312. The suction component 1321 is slidably connected to the first slide rail 1312a so that the suction component 1321 can move up and down along the third direction Z. The suction component 1321 can move relative to the first slide rail 1312a through the driving component 1322. The first slide rail 1312a can drive the suction component 1321 to move up and down, so as to lift the material of the infusion set 200 and move it, reducing the situation of motion interference during the movement.

[0033] Furthermore, there are multiple suction components 1321, which are arranged along the first direction X. There are also multiple first slide rails 1312a, which are arranged side by side. The driving end of any suction component 1321 is slidably connected to a first slide rail 1312a. Each driving cylinder corresponds to a first slide rail 1312a. Any suction component 1321 can slide independently on the first slide rail 1312a. Since the second material station 121 on the material transmission line 120 may have only one or more vacant states, any suction component 1321 can place the material on a vacant second material station 121. Any suction component 1321 can selectively release the infusion set 200 and place it on the corresponding vacant second material station 121, thereby improving the feeding effect on the material transmission line 120.

[0034] Optionally, refer to Figure 2As shown, a second slide rail 1313a is provided on the second moving member 1313 along the second direction Y. The first moving member 1312 is slidably connected to the second slide rail 1313a. A drive cylinder is mounted on the second moving member 1313 and is used to drive the first moving member 1312 to move along the second slide rail 1313a. The second slide rail 1313a is used to guide the displacement of the first moving member 1312, so that the first moving member 1312 and the suction assembly 132 can move relative to each other along the width direction of the feeding device 100, so as to facilitate the suction assembly. After the suction component 1321 of component 132 completes the suction of the infusion set 200 material at the first material station 111, it can move the infusion set 200 material along the second direction Y to the corresponding empty position of the first material station 111. The second slide rail 1313a can ensure the accuracy of the movement of the first moving component 1312, reduce the error caused by the relative movement of the first moving component 1312 between the first material station 111 and the second material station 121, avoid material jamming, improve the flexibility of the suction component 1321 in replenishing material, and thus improve the replenishment efficiency.

[0035] Optionally, refer to Figure 1 and Figure 2 As shown, the mobile platform 131 also includes a mounting platform 1314. A third slide rail 1314a is provided on the mounting platform 1314 along the first direction X. The second moving part 1313 is slidably connected to the third slide rail 1314a. That is, the driving cylinder can drive the second moving part 1313 to move along the length direction of the feeding device 100 on the third slide rail 1314a. The third slide rail 1314a ensures the accuracy of the movement of the second moving part 1313, so that the second moving part 1313 can move along the length direction of the transfer transmission line 110 or the length direction of the material transmission line 120, and can more conveniently adsorb or place the suction part 1321. The transfer and feeding of the suction part 1321 can be completed without the need for the transfer transmission line 110 or the material transmission line 120 to perform transmission cooperation.

[0036] In one embodiment, alternatively, such as Figure 1 As shown, the transmission direction of the transfer line 110 is parallel to the transmission direction of the material transfer line 120. Accordingly, the first material station 111 of the transfer line 110 is arranged along the transmission direction of the transfer line 110, and the second material station 121 of the material transfer line 120 is arranged along the transmission direction of the material transfer line 120. The transfer line 110 is used to store the infusion set 200 to be replenished on the material transfer line 120, so that the suction element 1321 can cooperate with the transfer line 110 to replenish the material transfer line 120, ensuring that the material transfer line 120 can always be in a full-load state. The full-load state means that any second material station 121 on the material transfer line 120 is equipped with an infusion set 200.

[0037] In one embodiment, optionally, combining Figure 3 and Figure 4 As shown, the suction component 1321 also includes a fixed component 1321a, an elastic component 1321c, and a movable component 1321b. The movable component 1321b is used to suction or place the infusion set 200. The movable component 1321b is movably connected to the fixed component 1321a. The elastic component 1321c abuts between the movable component 1321b and the fixed component 1321a, and the elastic component 1321c plays a buffering role to ensure that the movable component 1321b returns to its original position after relative movement. The movable component 1321b has a certain amount of movement relative to the fixed component 1321a, realizing a flexible connection between the movable component 1321b and the fixed component 1321a. When the movable component 1321b contacts the infusion set 200, it avoids the movable component 1321b squeezing the infusion set 200, which could cause damage or deformation to the infusion set 200, thereby improving the feeding effect.

[0038] For example, the elastic element 1321c is a constant pressure spring, the fixed element 1321a and the movable element 1321b are arranged perpendicularly, and the output end of the movable element 1321b forms a vacuum negative pressure state to facilitate the suction of the infusion set 200 or to release the vacuum negative pressure state to separate the infusion set 200 from the output end of the movable element 1321b.

[0039] Optionally, refer to Figure 5 As shown, the movable member 1321b is provided with a first connecting part 1321d and a second connecting part 1321e, and the fixed member 1321a is provided with a first through hole 1321f and a second through hole 1321g. The first connecting part 1321d passes through the first through hole 1321f, and an elastic member 1321c abuts between the first connecting part 1321d and the fixed member 1321a. The second connecting part 1321e passes through the second through hole 1321g, and another elastic member 1321c abuts between the second connecting part 1321e and the fixed member 1321a. The first connecting part 1321d is flexibly connected to the first through hole 1321f of the movable member 1321b, and the second connecting part 1321e is flexibly connected to the second through hole 1321g of the movable member 1321b, so that the first connecting part 1321d and / or the second connecting part 1321e can move, ensuring that the movable member 1321b has a large adjustment space and adjustment range.

[0040] For example, the movable part 1321b is provided with two limiting grooves 1321i. One limiting groove 1321i corresponds to the first connecting part 1321d, and the other limiting groove 1321i corresponds to the second connecting part 1321e. The two limiting grooves 1321i are used to engage the infusion set 200, so that when the suction part 1321 suctions the infusion set 200, it can limit the infusion set 200 to a certain extent and prevent the infusion set 200 from deviating.

[0041] Furthermore, such as Figure 5 As shown, the suction assembly 132 also includes a vacuum component 1323. The suction component 1321 is provided with a hollow suction tube 1321h. Each suction tube 1321h is connected to a vacuum component 1323 to form a negative pressure channel. The end of the suction tube 1321h away from the vacuum component 1323 is provided with a suction port. The suction port of the suction tube 1321h is close to the infusion set 200 to draw in the infusion set 200. The suction tube 1321h is located between the first connecting part 1321d and the second connecting part 1321e. The relative movement and fine adjustment of the first connecting part 1321d and the second connecting part 1321e will not affect or hinder the suction stability of the suction port. In addition, the vacuum component 1323 and the driving component 1322 are respectively provided on opposite sides of the first moving component 1312.

[0042] For example, the suction pipe 1321h can be fixedly connected to the fixing member 1321a, and the suction pipe 1321h passes through the movable member 1321b to ensure the suction stability of the suction port of the suction pipe 1321h.

[0043] It is easy to understand that the vacuum component 1323 can be a vacuum generator, which is a device that generates negative pressure. By actively pumping air or passively applying pressure difference, air is discharged from the suction pipe 1321h of the suction component 1321 to form a vacuum environment.

[0044] In one embodiment, alternatively, referencing Figure 1 As shown, the feeding device 100 also includes a feeding mechanism 140. The feeding mechanism 140 and the transferring mechanism 130 are located at opposite ends of the transfer line 110, respectively. The feeding mechanism 140 and the transferring mechanism 130 are designed to avoid motion interference. The feeding mechanism 140 is used to feed the transfer line 110 so that there is always enough infusion set 200 material at the first material station 111 of the transfer line 110. The feeding mechanism 140 can be a six-axis collaborative robot. The robot has better mobility and ensures high feeding efficiency when feeding the first material station 111 of the transfer line 110.

[0045] In summary, the material conveying line 120 of the replenishment device 100 is used to transport materials in the production process. The first material station 111 on the transfer conveying line 110 is used to temporarily store materials to be replenished. After the defective materials at the multiple second material stations 121 of the material conveying line 120 are unloaded, the corresponding second material station 121 is vacant, and the transfer conveying line 110 can transport materials so that the suction component 132 can suck them up. At least two suction components 1321 can simultaneously suck up multiple materials to be replenished at the first material station 111. Each suction component 1321 can suck up multiple materials to be replenished at the first material station 111. A first material station 111 is provided, and the material station 121 is moved along the second direction Y to the material conveyor line 120 to replenish the material station 121 which is in an empty state. The first material station 111 and the second material station 121 are set in parallel to ensure that the position and orientation of the material to be replenished are convenient for placement in the second material station 121. At least two suction components 1321 can be sequentially positioned to correspond to the empty second material station 121, thereby improving the replenishment efficiency, keeping the material conveyor line 120 at full load, ensuring the yield of material products on the material conveyor line 120, and thus improving production efficiency.

[0046] The present invention also provides a material production line, including the feeding device 100 described in any of the above embodiments. The material production line can be used for the processing, transmission, manufacturing and packaging of the infusion set 200. The material production line including the feeding device 100 has all the beneficial effects of the feeding device 100, which will not be described in detail here.

[0047] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0048] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
