[0002] Automatic assembly machines for needle products are key equipment in modern medical machinery. Although there are many designs for automatic assembly machines for needle products, there is still much room for improvement.
[0003] The quality of the needle is crucial to the entire needle product, especially the needle length and needle tip. For the control of needle length, subsequent inspection and rejection are important, but more important is the control of needle length accuracy, so as to better improve the product yield.
[0004] Regarding the length of the needle body, the length of the needle body exposed outside the needle seat is the effective length. Existing needle equipment has almost no precise control over the effective length of the needle body, and only performs post-detection to remove unqualified products. Utility Model Content
[0005] The purpose of the utility model is to provide a medical needle carrier and a needle length adjustment device to alleviate the technical problem that the existing needle equipment in the prior art has almost no precise control over the effective length of the needle body and only detects and removes unqualified products in the later stage.
[0006] The medical needle carrier provided by the utility model comprises a main body and a needle-containing hole, wherein the main body is provided with a containing groove, and the containing groove is used to contain the needle seat; the bottom of the containing groove is provided with the needle-containing hole; the top of the needle-containing hole is connected to the containing groove; a supporting surface is also provided in the main body, and the supporting surface is located below the needle-containing hole and is used to support the needle tip.
[0007] When using the main body to place the needle, the needle body is placed in reverse so that the needle tip is facing downward and abutting the supporting surface. The distance between the bottom of the receiving groove and the supporting surface is adjusted to the standard length of the finished needle, so that the effective length of the needle body can be accurately controlled, thereby improving the qualified rate of produced needle bodies.
[0008] Furthermore, the needle receiving hole includes a guide portion; the top end of the guide portion is connected to the bottom of the containing groove, and the guide portion is a structure that gradually widens from bottom to top.
[0009] The diameter of the top opening of the guide part is larger than the diameter of the bottom opening and the aperture of other parts of the needle hole except the guide part. The larger opening can facilitate the needle body to enter the needle hole.
[0010] Furthermore, the needle-containing hole also includes a limiting portion; the top end of the limiting portion is connected to the bottom end of the guide portion, and the limiting portion is a straight hole extending in the vertical direction, and the aperture of the straight hole is less than or equal to the aperture of the bottom end of the guide portion.
[0011] The limiting portion of the straight hole structure can limit the verticality of the needle body so that the verticality of the needle body meets expectations, and can prevent the needle body with burrs from falling into the limiting portion, thereby screening out the needle body with burrs.
[0012] Furthermore, a needle storage portion is also provided in the main body; the needle storage portion is located between the supporting surface and the needle receiving hole, and the bottom end of the needle receiving hole is connected to the needle storage portion.
[0013] The needle storage portion has a larger moving space in the horizontal direction, and the tip of the needle body is not easily damaged or deformed due to contact with the side wall when moving downward.
[0014] Furthermore, the main body includes a containing member and a bottom plate; the containing groove is arranged at the top of the containing member; the bottom plate is arranged at the bottom of the containing member and is detachably connected to the containing member, and the top surface of the bottom plate is the supporting surface.
[0015] During production of the main body of the combined structure, the containing part and the bottom plate can be produced separately and then assembled. In addition, when produced separately, it is easier to control the flatness of the top surface of the bottom plate, which facilitates processing and production.
[0016] Furthermore, observation ports are provided on both sides of the main body; the observation ports are communicated with the needle storage portion.
[0017] When the needle holder is placed in the holding slot, the needle body in the needle holder falls along the needle receiving hole, and the needle tip reaches the needle storage part and abuts against the supporting surface. The staff can check through the observation port whether the needle tip falls into the needle storage part smoothly, thereby understanding whether the position of the needle body has reached the preset position.
[0018] Furthermore, there are a plurality of the needle-accommodating holes; the plurality of the needle-accommodating holes are evenly and spaced apart in the containing groove.
[0019] Furthermore, the needle storage portion is connected to the plurality of needle receiving holes respectively.
[0020] Furthermore, there are a plurality of the containing grooves; the plurality of the containing grooves are arranged at intervals on the main body.
[0021] The utility model also aims to provide a needle length adjustment device, including a medical needle carrier.
[0022] Beneficial effects:
[0023] The medical needle carrier provided by the utility model comprises a main body, which is provided with a containing groove, in which a needle seat is contained; a needle hole is provided at the bottom of the containing groove; the top of the needle hole is connected to the containing groove; a supporting surface is also provided in the main body, which is located below the needle hole and is used to support the needle tip.
[0024] Specifically, unlike the prior art method of placing the needle tip upward, when the needle body in the utility model is installed in the needle seat, the needle tip of the needle body faces downward, and after glue is dispensed between the needle body and the needle seat, the needle seat is placed in the receiving groove, and the needle body enters the needle hole. Under the action of gravity, the needle body slides downward along the needle hole, and the verticality of the needle body can be controlled under the restriction of the top and bottom openings of the needle hole, so that the verticality of the needle body is maintained within a preset range. In addition, since the needle seat is fixed in the receiving groove, the bottom surface of the needle seat is aligned with the needle hole. The bottoms of the containing grooves are in contact with each other, and the needle body extends downward from the bottom of the needle seat. The distance between the bottom of the needle seat and the supporting surface is a fixed distance. The needle body slides until the needle tip abuts against the supporting surface and then stops moving. That is, the effective needle length of the needle body is the distance between the bottom of the containing groove and the supporting surface. The utility model holds the needle body by placing the needle body in reverse, and adjusts the distance between the bottom of the containing groove and the supporting surface to the standard length of the finished needle, thereby achieving accurate control of the effective length of the needle body, thereby improving the qualified rate of produced needle bodies.

[0042] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0043] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The medical needle body 300 carrier provided in this embodiment includes a main body 100 and a needle hole 111. The main body 100 is provided with a receiving groove 110, and the receiving groove 110 is used to receive the needle seat 200. The bottom of the receiving groove 110 is provided with a needle hole 111. The top of the needle hole 111 is connected to the receiving groove 110. A supporting surface is also provided in the main body 100, and the supporting surface is located below the needle hole 111 and is used to support the needle tip.
[0044] When the needle body 300 is installed in the needle seat 200, the needle tip of the needle body 300 faces downward. After the glue is dispensed between the needle body 300 and the needle seat 200, the needle seat 200 is placed in the receiving groove 110, and the needle body 300 enters the needle hole 111. The needle body 300 slides downward along the needle hole 111 under the action of gravity. Under the restriction of the top and bottom holes of the needle hole 111, the verticality of the needle body 300 can be controlled, so that the verticality of the needle body 300 is kept within a preset range. Furthermore, since the needle seat 200 is fixed in the receiving groove 110, the bottom surface of the needle seat 200 abuts against the bottom of the receiving groove 110, the needle body 300 extends downward from the bottom of the needle seat 200, and the distance between the bottom of the needle seat 200 and the supporting surface is a fixed distance, and the needle body 300 slides until the needle tip abuts against the supporting surface and then stops moving, that is, the effective needle length of the needle body 300 is the distance between the bottom of the receiving groove 110 and the supporting surface.
[0045] The needle body 300 in this embodiment is placed in reverse so that the needle tip faces downward, and the distance between the bottom of the containing groove 110 and the supporting surface is adjusted to the standard length of the finished needle, so that the effective length of the needle body 300 can be accurately controlled, thereby improving the qualified rate of the produced needle body 300.
[0046] The bottom of the containing tank 110 in this embodiment is circumferentially provided with a tank wall, and the plurality of tank walls and the tank bottom are combined to form a tank body with an opening at the top.
[0047] In addition, an extension portion 210 is provided at the bottom of the needle seat 200 in this embodiment, and the needle body 300 extends out of the needle seat 200 from the extension portion 210. When the needle seat 200 is loaded, the extension portion 210 is opposite to the position of the needle hole 111 in the receiving groove 110, and the needle body 300 extends out of the extension portion 210 and then is inserted into the needle hole 111.
[0048] As an implementable method, the containing groove 110 can be replaced by a limiting space enclosed by multiple columns and plates. Under this structure, after the needle seat 200 is placed in the limiting space, the bottom surface of the needle seat 200 abuts against the top surface of the limiting space, and multiple columns or multiple plates enclose the needle seat 200 in the middle limiting space.
[0049] In this embodiment, the needle receiving hole 111 includes a guide portion 112. The top of the guide portion 112 is connected to the bottom of the receiving groove 110, and the guide portion 112 is a structure that gradually widens from bottom to top.
[0050] The guide portion 112 gradually widens from bottom to top, and the diameter of the top opening of the guide portion 112 is larger than the diameter of the bottom opening and the aperture of the other parts of the needle hole 111 except the guide portion 112. The larger opening can facilitate the needle body 300 to enter the needle hole 111. When the needle holder 200 is placed in the receiving groove 110, the needle tip of the needle body 300 is located at the bottom, and the needle tip is easy to align with the top opening of the guide portion 112, so as to avoid the needle tip colliding with the bottom of the receiving groove 110 when the needle holder 200 is placed in the receiving groove 110, resulting in deformation and burrs on the needle tip.
[0051] In this embodiment, the needle hole 111 further includes a limiting portion, the top of which is connected to the bottom of the guide portion 112 , and the limiting portion is a straight hole extending in the vertical direction, and the diameter of the straight hole is less than or equal to the diameter of the bottom of the guide portion 112 .
[0052] See also Figure 5 , Figure 6 The guide portion 112 is gradually widened from bottom to top, and the limiting portion is a straight hole extending in the vertical direction, the aperture of the straight hole is less than or equal to the aperture of the bottom end of the guide portion 112, and the guide portion 112 is connected to the limiting portion.
[0053] Among them, the limiting part of the straight hole structure can limit the verticality of the needle body 300 so that the verticality of the needle body 300 meets expectations.
[0054] Furthermore, in order to prevent the diameter of the straight hole from being too small, which makes it difficult for the needle body 300 to slide downward under the action of gravity, the diameter of the hole should be at least 0.02 mm larger than the diameter of the needle body 300, so that the needle body 300 can fall normally in the straight hole. Specifically, the diameter of the straight hole in this embodiment is 0.02 mm larger than the diameter of the needle body 300. Under this structure, the verticality of the needle body 300 can be ensured to be better, and the needle body 300 can slide down in the straight hole due to gravity.
[0055] In addition, the limiting portion of the straight hole structure has a smaller diameter, and the gap between the hole wall and the needle body 300 is smaller. If there are burrs on the needle body 300, the limiting portion can limit the burrs so that the needle body 300 with the burrs cannot fall into the limiting portion, thereby further screening the needle body 300 and screening out the needle body 300 with the burrs.
[0056] In this embodiment, a needle storage portion 120 is further provided in the main body 100. The needle storage portion 120 is located between the supporting surface and the needle receiving hole 111, and the bottom end of the needle receiving hole 111 is connected to the needle storage portion 120.
[0057] Specifically, when the needle body 300 is connected to the needle seat 200 by glue injection, the needle body 300 will move downward under the influence of the colloid tension during the solidification process of the colloid, and the horizontal movement space of the needle storage part 120 is large, and the tip of the needle body 300 is not easily damaged or deformed due to contact with the side wall when moving downward. In this embodiment, the bottom end of the supporting surface and the needle hole 111 are spaced apart, and the space between the two is the needle storage part 120.
[0058] See also Figure 3 , Figure 4 As an implementable method, the limiting portion can adopt a structure that tapers from top to bottom, the top of the limiting portion is connected to the bottom of the guide portion 112 and the diameter of the top hole of the limiting portion is the same as the diameter of the bottom hole of the guide portion 112, the guide portion 112 is connected to the limiting portion and has a conical cross-section. Under this structure, it is very convenient for the needle body 300 to slide down.
[0059] In this embodiment, the main body 100 includes a receiving member 130 and a bottom plate 140. The receiving groove 110 is disposed at the top of the receiving member 130. The bottom plate 140 is disposed at the bottom of the receiving member 130 and is detachably connected to the receiving member 130, and the top surface of the bottom plate 140 is a supporting surface.
[0060] Specifically, the top surface of the bottom plate 140 in this embodiment is a planar structure, the needle receiving hole 111 in the receiving groove 110 extends downward, the lower end opening of the needle receiving hole 111 is opposite to the supporting surface, and the interval gap between the lower end opening of the needle receiving hole 111 and the supporting surface is the needle storage portion 120. After the needle body 300 completely falls into the needle receiving hole 111, the needle tip is located in the needle storage portion 120 and abuts against the top surface of the bottom plate 140.
[0061] The receiving member 130 and the bottom plate 140 are connected by snap-fitting. During production, the receiving member 130 and the bottom plate 140 can be produced separately and then assembled. When produced separately, it is easier to control the flatness of the top surface of the bottom plate 140, which facilitates processing and production.
[0062] In this embodiment, observation ports 150 are provided on both sides of the main body 100 , and the observation ports 150 are communicated with the needle storage portion 120 .
[0063] Among them, both sides of the main body 100 in this embodiment are provided with observation ports 150, which are opened in a direction perpendicular to the side wall of the main body 100 and communicated with the needle storage part 120. Specifically, when the observation port 150 in this embodiment is set, an observation groove is first opened on the side wall of the receiving part 130 and is located at the edge. When the receiving part 130 and the bottom plate 140 are combined, the receiving part 130 is buckled on the top surface of the floor, and the top surface of the bottom plate 140 and the observation groove are enclosed to form the observation port 150. When the needle holder 200 is placed in the receiving groove 110, after the needle body 300 in the needle holder 200 falls along the needle receiving hole 111, the needle tip reaches the needle storage part 120 and abuts against the supporting surface. The staff can check whether the needle tip falls into the needle storage part 120 smoothly through the observation port 150, so as to understand whether the position of the needle body 300 reaches the preset position.
[0064] As an implementable method, the main body 100 can also adopt an integrated structure, the bottom of the needle hole 111 is the needle storage part 120, and the bottom surface of the needle hole 111 is the supporting surface. Under this structure, the main body 100 is more stable and durable. Under this structure, the observation port 150 can be directly opened on the side wall of the main body 100, and the observation port 150 is connected to the bottom of the needle hole 111.
[0065] In this embodiment, there are a plurality of needle receiving holes 111. The plurality of needle receiving holes 111 are evenly and spaced apart in the receiving groove 110.
[0066] Each containing groove 110 has a plurality of needle holes 111 , which can store and accommodate a plurality of needle bodies 300 at the same time. Specifically, in this embodiment, each containing groove 110 has nine needle holes 111 evenly arranged therein, thereby supporting nine needle seats 200 and accommodating nine needle bodies 300 .
[0067] In this embodiment, the needle storage portion 120 is connected to the plurality of needle receiving holes 111 respectively.
[0068] In the present embodiment, all needle receiving holes 111 in each receiving groove 110 are connected to the same needle storage portion 120. Accordingly, the needle tips of all needle bodies 300 in each receiving groove 110 are located in the same needle storage portion 120 and abut against the same supporting surface. Under this structure, it can be ensured that the needle lengths of all needle bodies 300 in a single receiving groove 110 are the same.
[0069] Furthermore, in this embodiment, there are a plurality of receiving grooves 110 , and the plurality of receiving grooves 110 are arranged on the main body 100 at intervals.
[0070] The receiving member 130 is provided with a plurality of receiving grooves 110, and each receiving groove 110 is provided with nine needle holes 111, which can increase the number of needle holders 200 that can be carried by a single carrier, and accordingly, can further increase the number of needle bodies 300 that can be contained and accommodated by a single carrier. Specifically, in this embodiment, each receiving member 130 is provided with three receiving grooves 110, and the needle storage portions 120 at the bottom of the three receiving grooves 110 are all connected to the same bottom plate 140, so that the needle lengths of all the needle bodies 300 in the three receiving grooves 110 are the same.
[0071] The needle length adjustment device provided in this embodiment includes a medical needle body 300 carrier.
[0072] When storing needle bodies 300, the medical needle body 300 carrier can store multiple needle bodies 300 at the same time, and all needle bodies 300 are placed inverted so that the needle tips face downward. The distance between the bottom of the containing groove 110 and the supporting surface is adjusted to the standard length of the finished needle, so that the effective length of all the needle bodies 300 contained can be accurately controlled, thereby improving the qualified rate of the produced needle bodies 300.
[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
