[0041] Please refer to Figures 1 to 5The tape carrier reel easy to demould provided by the utility model can be arranged in a processing production line applied by SMT, for example.
[0042] Specifically, the tape carrier reel easy to demould comprises a main body 100, a first pressing plate 210 and a second pressing plate 220. The main body 100 is provided with an axle hole 110 for penetrating an axle. The first pressing plate 210 protrudes from the radial outer side of the main body 100. The second pressing plate 220 protrudes from the radial outer side of the main body 100. The second pressing plate 220 is axially spaced from the first pressing plate 210 to define a limiting groove 230 at the spacing. The limiting groove 230 surrounds the circumference of the main body 100 and is used for winding a tape.
[0043] The first pressing plate 210 and the second pressing plate 220 are respectively arranged at least two along the circumference of the main body 100. The axial projection of the first pressing plate 210 is arranged in a staggered manner with the axial projection of the second pressing plate 220.
[0044] In the technical scheme provided by the utility model, the radial outer side walls of the first pressing plate 210, the second pressing plate 220 and the main body 100 jointly define the limiting groove 230. Since the first pressing plate 210 and the second pressing plate 220 are respectively arranged in an intermittent manner along the circumference and the axial projections of the two are staggered, the mold part for forming the first pressing plate 210 and the mold part for forming the second pressing plate 220 can not interfere with each other in the axial direction. That is, the mold for forming the first pressing plate 210 and the mold for forming the second pressing plate 220 can be selectively demoulded on the two sides of the axial direction. Thus, according to actual needs, any suitable number of reels can be simultaneously formed in the axial direction and smoothly demoulded, which helps to simplify the demoulding operation and improve the demoulding efficiency.
[0045] The main body 100 is generally disc-shaped and has a central axis. The central axis of the axle hole 110 and the central axis of the main body 100 are generally collinear.
[0046] The shape and size of the axle hole 110 correspond to and adapt to the shape and size of the axle to be used. The axle hole 110 is generally provided as a circular hole. In order to realize the rotation-stopping cooperation between the axle hole 110 and the axle, rotation-stopping protrusions can be provided on one of the hole wall of the axle hole 110 and the radial outer side wall of the axle, and rotation-stopping grooves are provided on the other. The rotation-stopping protrusions and the rotation-stopping grooves are adapted to each other. For example Figures 1 to 5 In the structure shown, the hole wall of the axle hole 110 is provided with three rotation-stopping grooves. The three rotation-stopping grooves are arranged at equal intervals along the circumference of the axle hole 110.
[0047] The first pressing plate 210 and the second pressing plate 220 are respectively arranged protruding from the radial outer wall of the main body 100. It can be understood that all the first pressing plates 210 and the main body 100, all the second pressing plates 220 and the main body 100 can be integrally formed. Or, at least one first pressing plate 210 and the main body 100, at least one second pressing plate 220 and the main body 100 can be separately connected after being separately formed.
[0048] When detachable connection is performed, taking the first pressing plate 210 and the main body 100 as an example: the connection between the first pressing plate 210 and the main body 100 can be a fixed connection with relatively unchanged position. Or the connection between the first pressing plate 210 and the main body 100 can also be a movable connection with flexible position adjustment.
[0049] When the first pressing plate 210 and / or the second pressing plate 220 is / are movably connected to the main body 100 with flexible position adjustment, it / they can be axially movably connected. In this way, the slot width of the limiting slot 230 can be flexibly increased or decreased. In turn, the same easy-to-unmold carrier tape reel can be adapted to wind a carrier tape of multiple widths. It can be understood that by appropriately adjusting the relative positions of the first pressing plate 210 and the second pressing plate 220, the easy-to-unmold carrier tape reel can also be more suitable for the axial limiting of the carrier tape, which helps the stable winding of the carrier tape.
[0050] When the first pressing plate 210 and / or the second pressing plate 220 is / are movably connected to the main body 100 with flexible position adjustment, it / they can also be radially movably connected. In this way, the radial dimension of the first pressing plate 210 and / or the second pressing plate 220 can be increased or decreased. In turn, the same easy-to-unmold carrier tape reel can be adapted to wind a carrier tape of multiple thicknesses or lengths.
[0051] Next, if the main body 100 is defined to have a first axial end 101 and a second axial end 102 arranged opposite along the axial direction thereof, the first pressing plate 210 can be arranged closer to the first axial end 101. Or the plate surface of the first pressing plate 210 is substantially flush with the first axial end 101. The second pressing plate 220 is arranged closer to the second axial end 102. Or the plate surface of the second pressing plate 220 is substantially flush with the second axial end 102.
[0052] There is no limit to the number of first pressure plates 210 and second plates arranged at intervals along the circumference of the main body 100. They can be set to two or more as needed. Specifically, taking the first pressure plate 210 as an example: when two first pressure plates 210 are arranged at intervals along the circumference of the main body 100, these two first pressure plates 210 are arranged as symmetrically as possible about the central axis of the main body 100. When three first pressure plates 210 are arranged at intervals along the circumference of the main body 100, these three first pressure plates 210 are arranged at approximately equal intervals. For example… Figures 1 to 5 As shown in the structure, the first pressure plate 210 and / or the second pressure plate 220 can be specifically arranged in three equal intervals along the circumference of the main body 100. While ensuring that the wound carrier tape can be axially pressed, it also helps to simplify the processing and forming of the carrier tape reel, which is easier to demold.
[0053] The specific shape and size of the first pressure plate 210 and the second pressure plate 220 are not limited. For example, in Figures 1 to 5 In the structure shown, the first pressure plate 210 and / or the second pressure plate 220 are fan-shaped with gradually increasing width in the direction radially away from the main body 100. Specifically, the corners of the outer periphery of the fan shape of the first pressure plate 210 and / or the second pressure plate 220 are rounded to avoid forming relatively sharp corner structures. The fan-shaped arrangement of the first pressure plate 210 and / or the second pressure plate 220 creates a gradually increasing pressing surface, which is more conducive to axially limiting the wound carrier tape.
[0054] The first pressure plate 210 and / or the second pressure plate 220 can specifically be plate-shaped with uniform wall thickness. To save material, the first pressure plate 210 and / or the second pressure plate 220 are partially perforated along the axial direction. Perforations are formed at these perforations. The shape of the perforations can be adapted to the shape of the first pressure plate 210 or the second pressure plate 220 at that location, so that the structural strength of the first pressure plate 210 and / or the second pressure plate 220 is more uniform.
[0055] And / or, the first pressing plate 210 and the second pressing plate 220 are provided with a rib 240 on the side surface away from each other, and the rib 240 extends along the outer periphery of the first pressing plate 210 or the second pressing plate 220 at the location. The rib 240 can structurally reinforce the outer periphery of the first pressing plate 210 and / or the second pressing plate 220. Among them, the rib 240 on the radial inner periphery of the first pressing plate 210 and / or the second pressing plate 220 can be directly abutted and fixed with the radial outer side wall of the main body 100. The above does not constitute a limitation on the forming method of the rib 240. For example, the rib 240 can be integrally injection molded with the first pressing plate 210 and / or the second pressing plate 220 at the location. Or after the first pressing plate 210 and / or the second pressing plate 220 are injection molded, the rib 240 can be defined by stamping, cutting or other methods on the local plate surface of the first pressing plate 210 and / or the second pressing plate 220.
[0056] It should be noted that the above does not constitute a limitation on the specific structural parameters of each first pressing plate 210 and each second pressing plate 220 in the same easy-to-unload carrier tape reel. According to actual needs, each first pressing plate 210 and each second pressing plate 220 in the same easy-to-unload carrier tape reel can be set to have the same structural parameters, or at least part of the structural parameters can be different according to actual needs.
[0057] Based on one or more of the above embodiments, the first pressing plate 210 forms a first axial projection. The second pressing plate 220 forms a second axial projection. Any first axial projection and any second axial projection are arranged in a circumferential staggered manner. Among them, the first axial projection and the second axial projection adjacent to each other form a staggered gap 250. When the first pressing plate 210 and the second pressing plate 220 are respectively provided with a plurality of them, the staggered gap 250 also corresponds to a plurality of them.
[0058] Therefore, the radial outer side wall of the main body 100 can be recessed with a socket 140 at at least one staggered gap 250. The socket 140 is used to insert and fix the end of the carrier tape. Since the socket 140 is used to insert and fix the end of the carrier tape wound into a reel. If the carrier tape inserted into the socket 140 is defined as a proximal end tape segment. Then by opening the socket 140 at the staggered gap 250, it is convenient to directly use the staggered gap 250 to bend the proximal end tape segment of the carrier tape out of the limiting slot 230, and insert it into the socket 140. In this way, the extension length and bending degree of the proximal end tape segment of the carrier tape can be minimized to avoid the operation of inserting the carrier tape into the socket 140 being complicated and difficult to implement due to excessive bending degree, or causing the carrier tape to break.
[0059] The insertion hole 140 extends along a radial direction of the main body 100. When the main body 100 has the first axial end 101 near the first pressing plate 210 and the second axial end 102 near the second pressing plate 220, the insertion hole 140 can include a first hole section 141, a second hole section 142, and a third hole section 143 arranged along the radial direction.
[0060] The first hole section 141 extends through the first axial end 101 but not the second axial end 102. Thus, the first hole section 141 can be open at the first axial end 101 and define a second stop 145 at the second axial end 102. The second stop 145 can limit the proximal tape section of the carrier tape in a direction of the second axial end 102. Thus, the proximal tape section of the carrier tape can be effectively prevented from escaping from the first hole section 141 in the direction of the second axial end 102.
[0061] Similarly, the second hole section 142 extends through the second axial end 102 but not the first axial end 101. Thus, the second hole section 142 can be open at the second axial end 102 and define a first stop 144 at the first axial end 101. The first stop 144 can limit the proximal tape section of the carrier tape in a direction of the first axial end 101. Thus, the proximal tape section of the carrier tape can be effectively prevented from escaping from the second hole section 142 in the direction of the first axial end 101.
[0062] The third hole section 143 extends through both axial ends of the main body 100 and is open at the first axial end 101 and the second axial end 102, respectively.
[0063] It can be understood that the openings described above can provide a certain deflection space for the proximal tape section of the carrier tape. The cooperation of the first stop 144 and the second stop 145 can limit the proximal tape section of the carrier tape on both axial sides at different radial positions, thereby preventing the proximal tape section of the carrier tape from escaping axially from the insertion hole 140.
[0064] Specifically, the first hole section 141 is arranged radially inward of the third hole section 143, and the second hole section 142 is arranged radially outward of the third hole section 143. Thus, the proximal tape section of the carrier tape can be axially limited on opposite sections. Even if a certain deflection occurs in the middle section of the proximal tape section of the carrier tape, the proximal tape section of the carrier tape will not escape.
[0065] Further, the second stop 145 extends towards the first axial end 101 to close the opening of the insertion hole 140 at the location. That is, the second stop 145 is in the form of a shell covering the proximal tape section of the carrier tape on the side of the second axial end 102, on both circumferential sides, and radially inward. The proximal tape section of the carrier tape can be limited in the above four directions and prevented from being lifted up.
[0066] The forming mode of the insertion hole 140 is not limited, for example Figures 1 to 5 As shown, the main body 100 includes an end plate 120 and a side plate 130. The end plate 120 is provided with an axial hole 110. The plate segment of the end plate 120 close to the axial hole 110 is sunken from the first axial end 101 to form a first hole segment 141. And the plate segment of the end plate 120 at the second axial end 102 is locally raised to form a second stop portion 145. The plate segment of the end plate 120 away from the axial hole 110 is provided with a third hole segment 143 along the axial direction. In this way, the second stop portion 145 can be formed more simply.
[0067] The side plate 130 is arranged at the radial outer side of the end plate 120 and extends along the circumferential direction of the end plate 120. The side plate 130 protrudes from the axial two ends of the end plate 120 respectively. The side plate 130 is concave from the second axial end 102 to form a second hole segment 142 and a first stop portion 144 respectively.
[0068] The raised height of the end plate 120 is not greater than the protruding height of the side plate 130 relative to the end plate 120. In this way, the side plate 130 can reserve sufficient protruding height, and when subjected to axial pressure, the side plate 130 can bear the axial pressure in advance, avoiding the raised structure of the end plate 120 from being damaged due to excessive axial pressure.
[0069] In addition, when the misalignment gap 250 is arranged at least two along the circumferential direction of the main body 100 as described above, the main body 100 is provided with an insertion hole 140 at the at least two misalignment gaps 250. It can be understood that the number of the insertion holes 140 can be the same as the number of the misalignment gaps 250, and they are arranged one by one. Alternatively, the number of the insertion holes 140 can be less than the number of the misalignment gaps 250. At this time, the insertion hole 140 can be selectively arranged at any misalignment gap 250. For example Figure 5 As shown, when six misalignment gaps 250 are arranged equidistantly along the circumferential direction of the main body 100, three of them can be provided with an insertion hole 140.
[0070] Further, the hole diameters of the insertion holes 140 can be completely the same. So that the proximal end of the carrier tape can get the same limiting and fixing effect no matter which insertion hole 140 it is inserted into.
[0071] Or further, the hole diameters of the insertion holes 140 can be partially different or completely different. For example Figure 5 As shown, when the hole diameters of the three insertion holes 140 are D1, D2 and D3 respectively, D1, D2 and D3 can be completely different. And D1 < D2 < D3.
[0072] The above merely describes preferred embodiments of the present application, and is not intended to limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the inventive concept of the present application, as described in the present application specification and drawings, is included in the patent protection scope of the present application.
