Description

[Technical Field]

[0001] The present disclosure relates to a component holder unit, a holding member, and a manufacturing method using the component holder unit. More specifically, the present disclosure relates to a component holder unit having a holding member holding a plurality of components, the holding member, and a manufacturing method using the component holder unit. [Background technology]

[0002] As a conventional example, a sheet-type magnetic medium (component) described in Patent Document 1 is exemplified.

[0003] The conventional example described in Patent Document 1 (hereinafter referred to as the conventional example) has a substrate made of a polyethylene terephthalate (PET) film, a magnetic layer formed on the surface of the substrate, and an adhesive layer formed on the back surface of the substrate. The conventional example is attached to the surface of a release sheet (holding member) and held by the adhesive layer. A regular position detection signal (magnetic signal) is written onto the magnetic layer by a magnetic recording device.

[0004] Conventional examples are peeled off from a release sheet and used in rotary encoders incorporated into laser printers, digital cameras, etc., and linear encoders incorporated into measuring instruments, etc.

[0005] However, conventional components (sheet-type magnetic media) are attached to a holding member (release sheet) that is approximately the same size as the component. Therefore, when manufacturing products (such as rotary encoders and linear encoders) using conventional components, a process is required to peel the holding members off the conventional components one by one. Furthermore, as components become smaller, the holding members also become smaller, making it difficult to peel the holding members off the components. [Prior art documents] [Patent documents]

[0012] A component holder unit, a holder member, and a manufacturing method using the component holder unit according to embodiments of the present disclosure will be described in detail with reference to the drawings. However, each diagram described in the following embodiments is a schematic diagram, and the ratios of the sizes and thicknesses of the components do not necessarily reflect the actual dimensional ratios. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0013] (1) Overview of the component holder unit and holder member of the present disclosure 1, a component holding unit 1 according to an embodiment of the present disclosure (hereinafter abbreviated as component holding unit 1) includes a plurality of components 3 and a holding member 2 according to an embodiment of the present disclosure (hereinafter abbreviated as holding member 2). The holding member 2 is configured to hold the plurality of components 3.

[0014] The multiple components 3 are all of the same type. The components 3 in this embodiment are so-called magnetic scales used in a device 4 (linear encoder) described below. However, the components 3 are not limited to magnetic scales and may be, for example, heat dissipation sheets (graphite sheets) placed between an electronic component and a heat sink.

[0015] The holding member 2 has a base material 20 having a flat holding surface 200, and a plurality of adhesive portions 21 respectively interposed between the holding surface 200 of the base material 20 and the held surfaces 30 of the plurality of components 3 (see Figures 1 and 2).

[0016] The multiple adhesive portions 21 have a film-like main body 22, a first adhesive layer 23 provided on a first surface 221 of the main body 22, and a second adhesive layer 24 provided on a second surface 222 of the main body 22 (see FIG. 2 ). The adhesive strength between the first adhesive layer 23 and the held surface 30 of the component 3 is greater than the adhesive strength between the second adhesive layer 24 and the holding surface 200 of the base material 20. Each of the multiple adhesive portions 21 adheres the first adhesive layer 23 to the held surface 30 of one component 3 that corresponds to it one-to-one among the multiple components 3. Each of the multiple adhesive portions 21 adheres the second adhesive layer 24 to the holding surface 200 of the base material 20.

[0017] Thus, when a tensile force is applied to the component 3 held by the holding member 2, the adhesive force between the second adhesive layer 24 and the holding surface 200 of the base material 20 is relatively small, and therefore the second adhesive layer 24 is peeled off from the holding surface 200 of the base material 20. In other words, the component holding unit 1 is movable (transportable) while holding multiple components 3 on the holding member 2, and the components 3 can be easily peeled off from the base material 20 together with the adhesive portion 21. Therefore, the component holding unit 1 and the holding member 2 can reduce the number of manufacturing steps when manufacturing the device 4, compared to conventional examples in which release sheets had to be peeled off one by one from each component.

[0018] (2) Details of the component holder unit Next, the detailed configuration of the component holding unit 1 will be described.

[0019] (2-1) Parts details Component 3 is a magnetic scale used in a linear encoder. Component 3 is formed in a rectangular shape with a thickness that is sufficiently small compared to its length and width (see Figure 1). The magnetic scale has a synthetic resin base and a magnetic layer formed on the surface of the base. The magnetic layer is magnetized so that north and south poles are arranged alternately (see Figure 4). The back surface of the base, opposite the front surface on which the magnetic layer is formed, becomes the held surface 30 of component 3 (see Figures 2 and 4).

[0020] (2-2) Details of the holding member The holding member 2 has a base material 20 and a plurality of adhesive portions 21 (see FIG. 1).

[0021] The substrate 20 is formed in the shape of a rectangular flat plate from a synthetic resin material such as polyethylene terephthalate (see FIGS. 1 and 2). A layer (not shown) of a release agent (also called a mold release agent) is provided on the holding surface 200 of the substrate 20. Suitable examples of the release agent applied to the holding surface 200 include polymers with long-chain alkyl groups, compounds or polymers containing fluorine atoms, and silicone-based polymers.

[0022] A positioning portion 25 is provided at each of the four corners of the substrate 20. In this embodiment, these four positioning portions 25 are circular holes that penetrate the substrate 20 in the thickness direction of the substrate 20. However, the positioning portions 25 are not limited to holes, and may be, for example, protrusions that protrude in the thickness direction of the substrate 20, or notches provided at the edge of the substrate 20.

[0023] Each of the adhesive portions 21 has a main body 22, a first adhesive layer 23, and a second adhesive layer 24 (see FIG. 2). The thickness of the adhesive portion 21 is preferably 0.01 to 0.1 mm (preferably, approximately 0.01 to 0.03 mm). The size (length and width) of the adhesive portion 21 is preferably equal to or smaller than the size (length and width) of the component 3.

[0024] The main body 22 is formed in the shape of a rectangular film from a synthetic resin material such as polyester. The main body 22 is preferably colored a different color from the base material 20. For example, when the base material 20 is transparent or white, the main body 22 is preferably colored gray or black. However, the main body 22 may be colored a color other than gray or black (e.g., red, blue) as long as it is a color different from the base material 20.

[0025] The first adhesive layer 23 and the second adhesive layer 24 are each formed of the same material (acrylic adhesive). However, because a release agent layer is provided on the holding surface 200 of the substrate 20, the adhesive strength of the first adhesive layer 23 (peel adhesive strength from the held surface 30 of the component 3; the same applies below) is greater than the adhesive strength of the second adhesive layer 24 (peel adhesive strength from the holding surface 200 of the substrate 20; the same applies below). The unit of peel adhesive strength is Newtons per 10 millimeters (N / 10 mm) (see JIS Z0237 "Test methods for adhesive tapes and adhesive sheets").

[0026] For example, the adhesive strength of the first adhesive layer 23 is preferably about 20 to 30 times that of the second adhesive layer 24. Specifically, the adhesive strength of the first adhesive layer 23 is about 7.8 to 11.4, and the adhesive strength of the second adhesive layer 24 is about 0.36. The first adhesive layer 23 and the second adhesive layer 24 do not need to be made of the same material (adhesive). For example, the first adhesive layer 23 may be made of an acrylic adhesive, and the second adhesive layer 24 may be made of an adhesive having a lower adhesive strength than the acrylic adhesive, such as a urethane adhesive. When the second adhesive layer is made of an adhesive having a lower adhesive strength than the adhesive of the first adhesive layer, a release agent layer may not be provided on the holding surface 200 of the substrate 20.

[0027] Here, the adhesive portions 21 may be formed from a commercially available double-sided adhesive tape. For example, the adhesive portions 21 may be formed by cutting the double-sided adhesive tape to an appropriate size.

[0028] (2-3) Assembling the parts holder unit Next, we will explain the procedure for assembling the component holder unit 1. However, the assembly procedure described below is an example, and the order of some of the steps may be changed. Note that the assembly work described below is automated by an assembly machine (assembly device), but some of the assembly work may also be performed manually.

[0029] First, the substrate 20 is placed on the work table. At this time, the substrate 20 is positioned on the work table by the four positioning parts 25. For example, the substrate 20 is positioned on the work table by inserting four protrusions provided on the work table into the positioning parts 25.

[0030] Then, a plurality of adhesive portions 21 are arranged at equal intervals vertically and horizontally on the surface (holding surface 200) of the base material 20 (see FIG. 1). In the illustrated example, 20 adhesive portions 21 are arranged in five rows vertically and four rows horizontally. At this time, each adhesive portion 21 is placed on the holding surface 200 of the base material 20 with the second adhesive layer 24 oriented so as to contact the holding surface 200 of the base material 20.

[0031] Next, components 3 are placed one by one on the first adhesive layer 23 of each adhesive portion 21 (see FIGS. 1 and 3). Then, a constant pressure is applied by a roller to each of the components 3 placed on the adhesive portions 21. The pressure applied by the roller is, for example, 10 to 50 N / cm. 2 Preferably, the pressure is about (0.1 to 0.5 MPa). By applying the pressure by the roller, the component 3 is firmly attached to the first adhesive layer 23, and the second adhesive layer 24 is firmly attached to the holding surface 200 of the base material 20.

[0032] In this manner, the assembly of the component holder unit 1 is completed.

[0033] (3) Details of manufacturing method using component holder units Next, a manufacturing method using a component holder unit according to an embodiment of the present disclosure (hereinafter simply referred to as manufacturing method) will be described with reference to FIGS.

[0034] The manufacturing method of this embodiment is a method for manufacturing a device 4 shown in Fig. 5. The device 4 is, for example, a linear encoder mounted on a digital camera or the like. The linear encoder has a magnetic scale (component 3) and a magnetic detection unit 42, and is used to detect the position of a lens 40 in the optical axis direction or the distance traveled.

[0035] The lens 40 is held by a lens holder 41. The lens holder 41 is configured to be moved linearly in the optical axis direction of the lens 40 (the direction of the arrow in FIG. 5) by a motor (not shown).

[0036] Component 3 (magnetic scale) is attached to lens holder 41 and moves linearly together with lens holder 41. However, component 3 is attached to lens holder 41 so that the north and south poles of the magnetic layer are parallel to the direction of movement of lens holder 41 (see FIG. 5).

[0037] The magnetic detection unit 42 is configured to detect the relative position of the component 3 by utilizing the magnetoresistance effect. The magnetic detection unit 42 has a magnetic detection element that detects the magnetism of the component 3, an amplifier that amplifies the output signal of the magnetic detection element, and a processing circuit that processes the output signal amplified by the amplifier. Note that the magnetic detection element is preferably an MR (magnetoresistance effect) element, a GMR (giant magnetoresistance effect) element, a TMR (tunnel magnetoresistance effect) element, or the like.

[0038] Next, a manufacturing method of this embodiment will be described. However, the manufacturing method described below is an example, and the order of some of the steps may be changed. Note that the manufacturing method described below is automated using a manufacturing device, but some of the steps may also be performed manually.

[0039] First, the component holder unit 1 is placed on a table (not shown). At this time, the holder 2 is positioned on the table by the four positioning parts 25. For example, the holder 2 is positioned on the table by inserting four protrusions provided on the table into the positioning parts 25.

[0040] Next, one of the multiple components 3 held by the holding member 2 is sucked onto the tip of a robot arm (not shown). Then, the robot arm peels the component 3 from the holding surface 200 of the substrate 20 (see FIG. 6). At this time, because the adhesive strength of the first adhesive layer 23 is greater than the adhesive strength of the second adhesive layer 24, the adhesive portion 21 attached to the held surface 30 of the component 3 is peeled off from the holding surface 200 of the substrate 20 together with the component 3.

[0041] Next, the robot arm transports the component 3 and the adhesive portion 21 to the lens holder 41. Furthermore, the robot arm presses the second adhesive layer 24 of the adhesive portion 21 against the attachment position of the component 3 on the lens holder 41, thereby attaching the component 3 to the lens holder 41.

[0042] Then, when the work of attaching one component 3 to the lens holder 41 is completed, another component 3 of the component holding unit 1 is subsequently peeled off from the base material 20 by the robot arm and attached to the lens holder 41.

[0043] In this manner, the manufacture of device 4 using component holder unit 1 is completed.

[0044] Thus, the manufacturing method of this embodiment includes the steps of positioning the component holding unit 1 using the positioning portion 25 as described above, and peeling each of the components 3 together with the adhesive portions 21 from the base material 20 of the component holding unit 1. The manufacturing method of this embodiment further includes the step of attaching each of the components 3 peeled from the base material 20 to a lens holder 41.

[0045] According to the manufacturing method of this embodiment, components 3 with adhesive portions 21 attached thereto can be removed from the component holding unit 1, eliminating the need to remove release sheets one by one from each component as in the conventional method. As a result, the manufacturing method of this embodiment can reduce the number of manufacturing steps when manufacturing the device 4 compared to the conventional method.

[0046] (4) Other advantages of the component holder unit according to the embodiment In the component holding unit 1 described above, each of the adhesive portions 21 is formed to have dimensions that are no larger than the component 3. Therefore, in the component holding unit 1, each adhesive portion 21 is less likely to protrude outside the component 3, and therefore, foreign matter such as dust can be prevented from adhering to the adhesive portions 21.

[0047] In the component holding unit 1, the multiple adhesive portions 21 are aligned in one or more rows at intervals to adhere the second adhesive layer 24 to the holding surface 200 of the substrate 20. By aligning the multiple adhesive portions 21 on the holding surface 200 of the substrate 20, the component holding unit 1 can easily automate the task of attaching the multiple adhesive portions 21 to the holding surface 200 of the substrate 20.

[0048] Furthermore, in the component holding unit 1, the holding member 2 has one or more positioning portions 25 for determining the position of each of the plurality of components 3 with respect to the base material 20. Therefore, the component holding unit 1 can improve the workability when aligning and attaching the plurality of adhesive portions 21 to the holding surface 200 of the base material 20.

[0049] Furthermore, in the component holding unit 1, the positioning portions 25 are holes that penetrate the base material 20 in the thickness direction of the base material 20, so that the positioning portions 25 can be easily provided on the base material 20.

[0050] Furthermore, in the component holding unit 1, the main body 22 is colored a different color from the base material 20, which improves the distinguishability between the base material 20 and the main body 22. As a result, the component holding unit 1 improves the operability of each of the operations of attaching the adhesive portion 21 to the base material 20 and attaching the component 3 to the adhesive portion 21.

[0051] In the component holding unit 1, each of the multiple components 3 has a flat held surface 30 that is adhered to the first adhesive layer 23. In the component holding unit 1, since the held surfaces 30 of the components 3 are flat, the adhesive strength between the components 3 and the first adhesive layer 23 can be improved.
