[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0026] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0027] In related technologies, the spool used to protect the chip usually includes a spool body and two baffles located at both ends of the axial direction of the spool body. Since the ratio of the radial dimension to the thickness dimension of the baffles is relatively large, the baffles are easily bent and deformed by gravity.

[0028] To address the aforementioned problems, this application provides a chip protection device, including a reel and a support member. The reel includes a shaft and a first baffle and a second baffle respectively disposed at both ends of the shaft along its axial direction. The shaft can accommodate a film material encapsulated with a chip, and the first and second baffles can provide limiting protection for the film material and the chip on it. Furthermore, by designing the connection structure between the first baffle, the second baffle, and the support member, the support member can provide support between the first and second baffles when needed, and can be stably stored on either the first or second baffle when not needed, thereby preventing the support member from being lost and solving the problem of needing to manage the support member separately.

[0029] See Figures 1-3 In some embodiments, the chip protection device 1 includes a spool 10 and a support member 20. The spool 10 includes a shaft 11, a first baffle 12, and a second baffle 13. The shaft 11 is used for winding a film containing a chip. The first baffle 12 and the second baffle 13 are respectively disposed at both ends of the shaft 11 along the axial direction. The spool 10 is, for example, an injection-molded product. The first baffle 12 and the second baffle 13 may have the same or different shapes and dimensions. The first baffle 12 is, for example, a circular plate structure with a diameter of, for example, 530 mm and a thickness of, for example, 5 mm. The second baffle 13 is, for example, a circular plate structure with a diameter of, for example, 530 mm and a thickness of, for example, 5 mm. The cross-sectional shape of the support member 20 is, for example, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof.

[0030] The support member 20 has a first state and a second state. (See attached image) Figure 2 and Figure 3 In the first state, both ends of the support member 20 are connected to the first baffle 12 and the second baffle 13, respectively, and the support member 20 is connected to the first baffle 12 and the second baffle 13, for example, by a snap-fit ​​connection. Furthermore, in the first state, the support member 20 provides supporting force to the first baffle 12 and the second baffle 13, thus preventing the first baffle 12 and the second baffle 13 from bending and deforming. (See reference...) Figures 4-8 In the second state, the support member 20 is connected to one of the first baffle 12 and the second baffle 13. Thus, when the support member 20 is not needed to support between the first baffle 12 and the second baffle 13, the support member 20 can be stably stored on the first baffle 12 or the second baffle 13, which can prevent the support member 20 from being lost and solve the problem of needing to manage the support member 20 separately.

[0031] See Figure 2 and Figure 3In some embodiments, the support member 20 is provided with a first slot 21 and a second slot 22. The first slot 21 and the second slot 22 may have the same or different shapes and sizes. The shape of the first slot 21 may be, for example, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof. The shape of the second slot 22 may be, for example, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof.

[0032] The first baffle 12 is provided with a first buckle 121 that engages with the first slot 21, and the second baffle 13 is provided with a second buckle 131 that engages with the second slot 22. In the first state, the first buckle 121 engages with the first slot 21, and the second buckle 131 engages with the second slot 22. In this way, the support member 20 can stably provide support between the first baffle 12 and the second baffle 13.

[0033] Optionally, the first buckle 121 and the first baffle 12 are integrally formed. For example, the first buckle 121 and the first baffle 12 are injection molded. This simplifies the process and reduces costs.

[0034] Optionally, the size of the end of the first buckle 121 away from the first baffle 12 is smaller than the size of the end closer to the first baffle 12, so that the first buckle 121 can be more easily snapped into the first slot 21.

[0035] Optionally, the end of the first latch 121 away from the first baffle 12 is provided with a rounded corner to avoid scratching the operator.

[0036] Optionally, the second snap fastener 131 and the second baffle 13 are integrally formed. For example, the second snap fastener 131 and the second baffle 13 are injection molded. This simplifies the process and reduces costs.

[0037] Optionally, the size of the end of the second buckle 131 away from the second baffle 13 is smaller than the size of the end closer to the second baffle 13, so that the second buckle 131 can be more easily snapped into the second slot 22.

[0038] Optionally, the end of the second latch 131 away from the first baffle 12 is provided with a rounded corner to avoid scratching the operator.

[0039] See Figures 4-8In some embodiments, the first baffle 12 is provided with a third buckle 123, and the support member 20 is provided with a third slot 23 that engages with the third buckle 123. The shape of the third slot 23 is, for example, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof. In the second state, the third buckle 123 engages with the third slot 23. Thus, when the support member 20 is not needed to support the first baffle 12 and the second baffle 13, the support member 20 can be conveniently and quickly stored on the first baffle 12, which not only prevents the support member 20 from being lost but also improves the ease of operation.

[0040] In other embodiments, the second baffle 13 is provided with a third buckle 123, and the support member 20 is provided with a third slot 23 that engages with the third buckle 123. The shape of the third slot 23 is, for example, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof. In the second state, the third buckle 123 engages with the third slot 23. Thus, when the support member 20 is not needed to support the first baffle 12 and the second baffle 13, the support member 20 can be conveniently and quickly stored on the second baffle 13, which not only prevents the support member 20 from being lost but also improves the ease of operation.

[0041] Optionally, both the first baffle 12 and the second baffle 13 are provided with a third latch 123, and the support member 20 is provided with a third slot 23 that engages with the third latch 123. The shape of the third slot 23 is, for example, circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, or a combination thereof. In the second state, the third latch 123 engages with the third slot 23. In the second state, the support member 20 can be connected to the first baffle 12 or the second baffle 13 depending on the actual situation. This improves operational flexibility.

[0042] In some embodiments, the first slot 21 is reused as the third slot 23. In other words, in the first state, the first slot 21 engages with the first latch 121 to fix the support member 20 between the first baffle 12 and the second baffle 13, thereby preventing the first baffle 12 and the second baffle 13 from bending or deforming. In the second state, the first slot 21 engages with the third latch 123 to fix the support member 20 onto the first baffle 12, thereby preventing the support member 20 from being lost. Thus, the same slot serves different functions in two different states, simplifying the overall structure and reducing costs.

[0043] In other embodiments, the second slot 22 is reused as the third slot 23. In other words, in the first state, the second slot 22 engages with the second latch 131 to fix the support member 20 between the first baffle 12 and the second baffle 13, thereby preventing the first baffle 12 and the second baffle 13 from bending or deforming. In the second state, the second slot 22 engages with the third latch 123 to fix the support member 20 onto the second baffle 13, thereby preventing the support member 20 from being lost. Thus, the same slot serves different functions in two different states, simplifying the overall structure and reducing costs.

[0044] See Figure 4 and Figure 7 In some embodiments, the first baffle 12 is provided with a receiving groove 122, and the third buckle 123 is disposed in the receiving groove 122. In the second state, the support member 20 is located in the receiving groove 122. Thus, when the support member 20 is stored on the first baffle 12, the support member 20 is hidden in the receiving groove 122, thereby preventing the support member 20 from being accidentally touched and falling off.

[0045] In other embodiments, the second baffle 13 is provided with a receiving groove 122, and the third buckle 123 is disposed within the receiving groove 122. In the second state, the support member 20 is located within the receiving groove 122. Thus, when the support member 20 is housed in the second baffle 13, the support member 20 is hidden within the receiving groove 122, thereby preventing the support member 20 from being accidentally touched and falling off.

[0046] Optionally, both the first baffle 12 and the second baffle 13 are provided with receiving grooves 122, and both the first baffle 12 and the second baffle 13 are provided with third buckles 123, which are disposed within the receiving grooves 122. Thus, in the second state, the support member 20 can be selectively stored in either the first baffle 12 or the second baffle 13 according to the actual situation, improving operational flexibility.

[0047] Continue reading Figure 4 and Figure 7 In some embodiments, the opening of the receiving groove 122 is provided with a blocking member 124. In the second state, the orthographic projection of the blocking member 124 onto the bottom of the receiving groove 122 overlaps with the orthographic projection of the support member 20 onto the bottom of the receiving groove 122. Thus, when the support member 20 is housed in the receiving groove 122, the third latch 123 and the blocking member 124 can prevent the support member 20 from moving in two mutually perpendicular directions, thereby further improving the stability of the support member 20. It is understood that when it is necessary to remove the support member 20 from the receiving groove 122 to switch to the first state, the elasticity of the support member 20, such as that of an injection-molded product, can be used to pull the support member 20 out from under the obstruction of the blocking member 124.

[0048] Optionally, blocking members 124 are provided on both sides of the receiving slot 122 to further improve the stability of the blocking members 124 during storage.

[0049] Optionally, the two blocking members 124 are arranged symmetrically, so that when the support member 20 is pulled out, the force is more evenly distributed, thereby improving the convenience of operation.

[0050] Optionally, the shape of the blocking element 124 can be triangular, semi-circular, quadrilateral, or a combination thereof, which can be selected according to design requirements.

[0051] Optionally, the blocking member 124 is quadrilateral in shape, and the free end of the blocking member 124 is rounded to avoid scratching the operator and also to avoid scratching the support member 20.

[0052] In some embodiments, the support member 20 is provided with a connecting shaft 24, the axis of which is perpendicular to the extending direction of the receiving groove 122, and the connecting shaft 24 slides in conjunction with the receiving groove 122 along the extending direction of the receiving groove 122. In this way, the support member 20 can switch states more smoothly.

[0053] Optionally, the first baffle 12 is provided with a receiving groove 122 and a first limiting groove communicating with the receiving groove 122, and the second baffle 13 is provided with a second limiting groove. The first baffle 12 is circular, the receiving groove 122 extends radially along the first baffle 12, and the limiting groove extends axially along the first baffle 12. In the second state, the support member 20 is located in the receiving groove 122, and the support member 20 slides sequentially along the extending direction of the receiving groove 122 and the extending direction of the first limiting groove to switch to the first state. In this way, the support member 20 can achieve smoother state switching.

[0054] In some embodiments, the chip protection device 1 includes a plurality of support members 20, which are arranged at intervals along the circumference of the shaft 11. The number of support members 20 is, for example, 2, 3, 4, 5, 6 or more. Optionally, the plurality of support members 20 are arranged at uniform intervals along the circumference of the shaft 11. This improves the uniformity of force distribution on the first baffle 12 and the second baffle 13.

[0055] See Figure 1 and Figure 4 In some embodiments, the first baffle 12 is provided with a hollow portion 12a. The shape of the hollow portion 12a is, for example, a regular shape such as a circle, ellipse, triangle, fan shape, quadrilateral, pentagon, or hexagon, or an irregular shape formed by a combination of multiple shapes. In this way, the weight of the first baffle 12 can be reduced, thereby reducing the risk of the first baffle 12 bending and deforming.

[0056] In other embodiments, the second baffle 13 is provided with a cutout portion 12a. The cutout portion 12a may be a regular shape, such as a circle, ellipse, triangle, fan shape, quadrilateral, pentagon, or hexagon, or an irregular shape formed by a combination of multiple shapes. In this way, the weight of the second baffle 13 can be reduced, thereby reducing the risk of the second baffle 13 bending and deforming.

[0057] Optionally, both the first baffle 12 and the second baffle 13 are provided with a hollow portion 12a, thereby reducing the weight of the first baffle 12 and the second baffle 13 and reducing the risk of deformation of the first baffle 12 and the second baffle 13.

[0058] In some embodiments, the first baffle 12 includes a plurality of hollow portions 12a and a plurality of blocking portions 12b, which are arranged alternately along the circumference of the shaft 11. In this way, the structural strength of the first baffle 12 is ensured while the weight of the first baffle 12 is reduced.

[0059] In other embodiments, the second baffle 13 includes a plurality of hollow portions 12a and a plurality of blocking portions 12b, which are arranged alternately along the circumference of the shaft 11. In this way, the structural strength of the second baffle 13 is ensured while the weight of the second baffle 13 is reduced.

[0060] Optionally, the first baffle 12 includes multiple hollow portions 12a and multiple blocking portions 12b, which are arranged alternately along the circumference of the shaft 11. Similarly, the second baffle 13 includes multiple hollow portions 12a and multiple blocking portions 12b, which are also arranged alternately along the circumference of the shaft 11. Thus, both the first baffle 12 and the second baffle 13 possess strong structural strength and light weight.
