[0002] In semiconductor manufacturing, reels are commonly used to wind tape. These reels consist of a central shaft and two end reels, one attached to each end of the shaft. The tape is wound around the shaft. After winding, multiple clips secure the outer edges of the two end reels, securing the tape in place and preventing deformation. Figure 1 Schematic diagram of the fastener 300 is shown. Figure 1 As shown, the latch 300 includes a latch body 31 and two latch arms 32. The two latch arms 32 are connected to opposite sides of the latch body 31, and a slot 33 is formed between each latch arm 32 and the latch body 31. The inner side surfaces of the two latch arms 32 facing the slot 33 are provided with latch protrusions 34 that protrude into the slot 33. The two latch arms 32 are mirror images of each other. When the latch 300 is attached to the reel, the two end discs of the reel extend into the two slots 33 of the latch, and the latch protrusions 34 of each latch abut against the outer side surfaces of the corresponding end discs, thereby clamping the reel.

[0003] In the prior art, the outer side surface of the end plate against which the snap protrusion 34 abuts is planar, causing the snap member to easily slide along the end plate, thereby affecting the positioning effect of the snap member. Summary of the Invention

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Figures 2 to 5 The structure of the reel according to the embodiment of the present invention is shown. Figures 2 to 5 According to an embodiment of the present invention, a reel 100 includes an intermediate shaft 1 and two end discs 2 , and the two end discs 2 are respectively connected to the two ends of the intermediate shaft 1 .

[0017] The outer surface of each end plate 2 is provided with a plurality of snap-on protrusions 21 and a plurality of ribs 22 in the circumferential direction. The plurality of snap-on protrusions 21 and the plurality of ribs 22 are all adjacent to the outer edge of the end plate 2, and the plurality of snap-on protrusions 21 and the plurality of ribs 22 are arranged in an interlaced manner. Each snap-on protrusion 21 is flanked by ribs 22, and each rib 22 is flanked by snap-on protrusions 21. Preferably, the plurality of snap-on protrusions 21 are evenly distributed in the circumferential direction. Each rib 22 can be a whole continuously extending rib, such as Figure 2 As shown, it can also be composed of multiple rib segments arranged at intervals.

[0018] The snap-fit protrusions 21 on the two end discs 2 are mirror-symmetrical to each other, and the ribs 22 on the two end discs 2 are mirror-symmetrical to each other.

[0019] In this embodiment, each end plate 2 has a circular shape, and each rib 22 is arc-shaped. Each end plate 2 comprises an intermediate shaft connecting plate 2a, a middle ring 2b, an outer ring 2c, multiple first connecting portions 2d, and multiple second connecting portions 2e. The intermediate shaft connecting plate 2a is connected to the intermediate shaft 1, while the middle ring 2b surrounds the intermediate shaft connecting plate 2a. Multiple first connecting portions 2d are disposed between the middle ring 2b and the intermediate shaft connecting plate 2a, spaced circumferentially. Each first connecting portion 2d has its ends connected to the middle ring 2b and the intermediate shaft connecting plate 2a, respectively. The outer ring 2c surrounds the middle ring 2b, while multiple second connecting portions 2e are disposed between the outer ring 2c and the middle ring 2b, spaced circumferentially. Each second connecting portion 2e has its ends connected to the outer ring 2c and the middle ring 2b, respectively. Multiple snap-fit protrusions 21 and multiple ribs 22 are provided on the outer ring 2c.

[0020] Furthermore, an annular reinforcing rib 23 is provided on the outer side surface of the outer ring 2 c near the inner edge, and radial reinforcing ribs 24 are connected between the annular reinforcing rib 23 and each convex rib 22 .

[0021] Figure 6 and Figure 7 The following diagrams illustrate a partially enlarged view of a reel assembly according to an embodiment of the present invention from different perspectives. The reel assembly according to an embodiment of the present invention includes the aforementioned reel 100 and a plurality of latches 300. The number of latches 300 is the same as the number of latching protrusions 21 on each end disc 2 of the reel 100.

[0022] Each latch 300 includes a latch body 31 and two latch arms 32. The two latch arms 32 are respectively connected to two opposite sides of the latch body 31. A slot 33 is formed between each latch arm 32 and the latch body 31. The inner side surfaces of the two latch arms 32 facing the slot 33 are provided with a latch protrusion 34 protruding into the slot.

[0023] The two end discs 2 of the reel 100 extend into the two slots 33 of each latch 300, and the latch protrusions 34 of each latch 300 latch onto the lower surface 211 of the corresponding latch protrusion 21. By making the latch protrusions 34 of the latch engage with the lower surface 211 of the latch protrusion 21, the end discs 2 of the reel 100 and the latch 300 are securely positioned, preventing the latch 300 from sliding relative to the end disc 2 after being latched and connected.

[0024] In this embodiment, the latching arm 32 of each latching member 300 is located between two corresponding ribs 22. Figure 7 shown.

[0025] In order to facilitate the removal of the fastener 300, preferably, the lower surface 211 of each fastening protrusion 21 has an inclined portion 211a, and the inclined direction of the inclined portion 211a is gradually inclined toward the inner side of the fastening protrusion 21 from the bottom of the fastening protrusion 21 to the top of the fastening protrusion 21. Figure 6 As shown, the longitudinal cross-section of each buckle protrusion 21 is trapezoidal, and the width of the trapezoid gradually widens from the top toward the bottom of the buckle protrusion 21.

[0026] In this embodiment, the end surface 221 of each rib 22 gradually slopes inward from the bottom to the top to facilitate demolding after injection molding. The top of each rib 22 has an arc chamfer 222 to prevent scratching the outer packaging of the reel.

[0027] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
