[0001] The utility model relates to the technical field of press needles, in particular to a positioning structure for spherical injection molded press needles. Background Art

[0002] The head end of a spherical press needle needs to be injection molded and dispensed with glue. In the existing injection molding method, a single needle body is first placed in the positioning hole of the mold, and after positioning the needle body, the head end of the needle body is injected and dispensed with glue. This method is cumbersome in processing, extremely labor-consuming, and not conducive to continuous production; for this reason, we propose a positioning structure for spherical injection molded press needles. Summary of the Utility Model

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to the attached Figures 1-5 , a positioning structure of a spherical injection press needle, including a carrier 1, at least one separable release paper 2 is pasted on the carrier 1, and a layer of medical adhesive tape 3 is also pasted at the center of each separable release paper 2, and a bottom film 4 is pasted at the bottom of the carrier 1;

[0030] The separable release paper 2 is divided into an independent left separation tab 2.1 and a right separation tab 2.2. The bottom of the left separation tab 2.1 is coated with an adhesive layer for pasting on the carrier 1, and the right separation tab 2.2 is joined with the left separation tab 2.1 through the medical adhesive tape 3. Specifically, a part of the medical adhesive tape 3 is pasted with the right separation tab 2.2, and the remaining part is pasted on the left separation tab 2.1;

[0031] Positioning grooves are provided at the positions corresponding to the needle body on both the left separation tab 2.1 and the right separation tab 2.2, and the positioning grooves of the two tabs can be joined to form a positioning hole 5 for facilitating the positioning of the needle body;

[0032] The carrier 1 is in a thin sheet shape, and the surfaces available for other structures to be pasted only include two surfaces (i.e., the bottom and the top). The material of the carrier 1 is PET;

[0033] For a single separable release paper 2, limiting holes are provided on the carrier 1 on both sides of the separable release paper 2. Preferably, the number of limiting holes on each side is two, and they are respectively arranged at the head and tail ends of the separable release paper 2.

[0034] In some embodiments, a plurality of separable release papers 2 are pasted on the carrier 1. As Figure 1 shown in one of the styles of the carrier 1, the carrier 1 is in a long strip shape, and the longitudinal cross-sectional shape is rectangular. A plurality of separable release papers 2 are arranged at intervals in a row along the length direction of the carrier 1;

[0035] For the separable release paper 2 arranged in a column at intervals, what remains unchanged is that a number of limiting holes are provided on both sides of the carrier 1 in a column. What is different is that the virtual line B formed between the limiting holes at the same horizontal position is located between the intervals of the adjacent separable release papers 2;

[0036] In some other embodiments, a column of separable release papers 2 is evenly divided into several parts, and each part includes at least two separable release papers 2. The virtual line B formed between the limiting holes at the same horizontal position is located between the intervals of the adjacent two parts of separable release papers 2 to reduce the number of punching operations. Preferably, the number of limiting holes on one side of each part of the separable release paper 2 is two.

[0037] An adhesive layer is coated on the bottom film 4. The needle body sequentially penetrates through the medical adhesive tape 3, the separable release paper 2 (positioning hole 5), the carrier 1, and the bottom film 4. The tip part at the tail end of the needle body penetrates through the bottom film 4 and extends out. The head end of the needle body is exposed outside the medical adhesive tape 3, facilitating subsequent injection and dispensing operations on the head end of the needle body.
