Description

Technical Field

[0001] This utility model relates to the technical field of medical device manufacturing equipment, and in particular to a UV curing device. Background Technology

[0002] The Luer lock is a standardized micro-drainage connector, a convenient connection device used in the medical industry. It is primarily used to connect to the outlet end of a syringe, allowing the syringe to be connected to the needle via the Luer lock.

[0003] During the production process, the Luer lock head is glued to the outlet end of the syringe, and the glue is cured by UV light to make the connection between the Luer lock head and the syringe more secure.

[0004] However, during the transfer of the injection syringe, the Luer lock head is often not aligned with the injection syringe before the adhesive is irradiated by the UV lamp. This misalignment of the Luer lock head after the adhesive has cured results in a low yield of finished products. Utility Model Content

[0005] The purpose of this invention is to provide a UV curing device to alleviate the technical problem in the prior art where the misalignment of the Luer lock head relative to the injection syringe results in a low yield rate of syringes after adhesive curing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a UV curing device, including a straightening mechanism, a curing mechanism and a conveying mechanism, wherein the conveying mechanism is used to fix the injection syringe in the vertical direction; The straightening mechanism includes a clamping component and a driving component. The clamping component is located above the conveying mechanism and is disposed opposite to the conveying mechanism. The curing mechanism is located on both sides of the straightening mechanism, and the curing mechanism is used to cure the glue between the injection syringe and the Luer lock head by light. The driving component is connected to the clamping component in a transmission manner, and the driving component is used to drive the clamping component to open or close. When the clamping component is closed, it straightens the material to be cured. When the clamping assembly is opened, it has a channel through which the material to be cured can pass.

[0007] Furthermore, the clamping assembly includes two sets of clamping units, and each set of clamping units is connected to the driving assembly; Each set of clamping units has a semi-circular clamping groove, and the clamping grooves of the two sets of clamping units are distributed opposite to each other. The drive assembly is used to drive the two sets of clamping units closer together until the corresponding clamping grooves are enclosed to form a circular limiting part, which is used to limit the Luer lock head.

[0008] Furthermore, each of the clamping units includes a sliding block, a connector, and a clamping member. One end of the connector is connected to the driving assembly via the sliding block, and the other end of the connector is provided with the clamping member. The clamping member has a clamping groove on one side of the clamping unit facing the other side.

[0009] Furthermore, the clamping member is provided with a plurality of clamping slots spaced apart along its extension direction, and the plurality of clamping slots are used to simultaneously clamp a plurality of Luer lock heads.

[0010] Furthermore, the driving assembly includes a driving member and a slide rail, and the sliding block is slidably connected to the slide rail; The driving element is connected to the sliding block, and the driving element is used to drive the corresponding sliding block to move along the slide rail.

[0011] Furthermore, the straightening mechanism also includes a connecting frame, on which the drive assembly is mounted.

[0012] Furthermore, the UV curing device also includes a frame structure, which includes an outer cover, a support plate, and support legs. The support plate is supported by multiple support legs, and the outer cover is provided on the outside of the support legs. The support plate is connected to the straightening mechanism and the curing mechanism respectively.

[0013] Furthermore, the curing mechanism includes a UV lamp and a connecting plate, wherein the UV lamp is connected to the support plate via the connecting plate; The UV lamps are distributed toward the clamping part of the clamping assembly to irradiate and cure the adhesive at the connection between the Luer lock head and the injection syringe.

[0014] Furthermore, the curing mechanism is provided in multiple sets, and the multiple sets of curing mechanisms are distributed at intervals along the extension direction of the support plate, so that the multiple sets of curing mechanisms are used to continuously irradiate the material.

[0015] Furthermore, the delivery mechanism includes a fixing clamp and a support, the fixing clamp being connected to the support, and the fixing clamp being used to clamp the injection syringe in a vertical direction.

[0016] This invention can achieve the following beneficial effects: In a first aspect, this utility model provides a UV curing device, including a straightening mechanism, a curing mechanism, and a conveying mechanism. The conveying mechanism is used to fix the injection syringe in a vertical direction. The straightening mechanism includes a clamping component and a driving component. The clamping component is located above the conveying mechanism and is arranged opposite to the conveying mechanism. The curing mechanism is located on both sides of the straightening mechanism and is used to cure the glue between the injection syringe and the Luer lock head by light irradiation. The driving component is connected to the clamping component in a transmission manner, and the driving component is used to drive the clamping component to open or close. When the clamping component is closed, it straightens the material to be cured. When the clamping component is open, it has a channel through which the material to be cured can pass.

[0017] In this invention, the Luer lock head and the syringe are bonded together with adhesive, which requires UV curing. However, the Luer lock head is prone to misalignment relative to the syringe during transport. In use, the syringe with the Luer lock head bonded is sequentially passed through a curing mechanism via a conveying mechanism to achieve UV curing of the adhesive. To prevent misalignment between the Luer lock head and the syringe before curing, a straightening mechanism is used to straighten the Luer lock head. It should be noted that the clamping assembly includes two sets of clamping units. The straightening method of the clamping assembly is as follows: when the clamping assembly is closed, the two clamping units close together clamp the Luer lock head to straighten it relative to the syringe; when the clamping assembly is open, a gap is created between the two separated clamping units, which serves as a channel for the material to be cured.

[0018] Compared with the prior art, the UV curing device provided by this utility model provides a clamping structure at one end of the delivery mechanism to straighten the Luer lock head that is misaligned when connected to the injection syringe. This prevents the Luer lock head from being fixed in a misaligned state relative to the injection syringe after the glue is cured by irradiation through the curing mechanism, thereby effectively ensuring the yield rate of the syringe.

[0019] In summary, this utility model at least alleviates the technical problem in the prior art where the misalignment of the Luer lock head relative to the injection syringe results in a low yield rate of syringes after the glue curing process. Attached Figure Description

The curing mechanism 2 is located on both sides of the straightening mechanism 1 and is used to cure the glue between the injection syringe and the Luer lock head by light. The driving assembly 12 is connected to the clamping assembly 11 and is used to drive the clamping assembly 11 to open or close. When the clamping assembly 11 is closed, it straightens the material to be cured. When the clamping assembly 11 is open, it has a channel through which the material to be cured can pass.

[0031] This invention at least alleviates the technical problem in the prior art where the misalignment of the Luer lock head relative to the syringe barrel results in a low yield rate of syringes after the glue curing process.

[0032] In this embodiment of the invention, the Luer lock head and the syringe are bonded together with adhesive, which needs to be cured by UV light.
