Description

Technical Field

[0001] This utility model relates to the technical field of bonding fixtures, specifically to a bonding fixture applied to SCF. Background Technology

[0002] SCF (Surface Mount Cell) is a component in the mobile phone LCD screen assembly. It is generally made of a composite of copper foil and foam. The copper foil provides electromagnetic shielding, while the foam dissipates heat. Before the SCF is attached to the screen, a protective film is usually applied to the copper foil surface to protect it, and a release film is applied to the foam adhesive side of the SCF.

[0003] However, the traditional SCF lamination method simply involves placing the SCF on a table and then manually aligning the corresponding protective film or release film by eye before laminating it. Because the relative position of the SCF and the protective film or release film cannot be precisely controlled, this easily leads to poor lamination accuracy and low efficiency.

[0004] Therefore, there is an urgent need for a bonding fixture for SCF to solve the problem of inconvenient SCF lamination. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a bonding fixture for SCF (Self-Contracted Frost) to solve the problem of inconvenient SCF lamination.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bonding fixture for SCF (Superficial Carbon Fiber) is characterized by comprising four rectangular block-shaped supports and a positioning structure. Each support has a rectangular SCF sub-mounting groove. The four supports can be assembled to form a rectangular base. The upper end face of the rectangular base has an SCF mounting groove formed by the four interconnected SCF sub-mounting grooves. The positioning structure includes a support block and an adjusting block. The support block is vertically positioned in the middle of the adjusting block and is used to be inserted parallel between any two supports. The adjusting block abuts against the side of the support away from the SCF mounting groove. The upper end face of the adjusting block has several positioning pins. The adjusting block also has an adjusting structure for adjusting the distance between the supports located on both sides of the support block.

[0008] To optimize the above technical solution, the specific measures also include:

[0009] Furthermore, the adjustment structure includes a bidirectional lead screw and two positioning plates. An adjustment cavity is formed axially in the adjustment block, and a bidirectional lead screw is rotatably arranged axially in the adjustment cavity. One end of the bidirectional lead screw extends out of the adjustment block. The adjustment block is located near the support block and on the left and right sides of the support block. A sliding groove is symmetrically formed about the support block along the axial direction of the adjustment block. The two positioning plates extend out of the sliding adjustment block and are arranged in one of the sliding grooves, and are threadedly connected to the bidirectional lead screw. The bidirectional lead screw is used to rotate and drive the two positioning plates to move close to or away from each other along the sliding groove.

[0010] Furthermore, the support block has storage slots on both sides of the end near the adjustment block that are connected to the slide groove on the same side, and the positioning plate can slide along the slide groove and be stored in the storage slot.

[0011] Furthermore, along the axial direction of the adjusting block, the width of the positioning plate is consistent with the depth of the receiving groove.

[0012] Furthermore, a rotating handle is installed at the end of the bidirectional lead screw extending from the adjusting block, and the rotating handle is used to drive the bidirectional lead screw to rotate.

[0013] Furthermore, the bidirectional lead screw is rotatably mounted in the adjusting block via a bearing.

[0014] Furthermore, several of the positioning pins are arranged along the axial direction of the adjusting block.

[0015] Furthermore, at least two positioning pins are provided.

[0016] Furthermore, the horizontal height of the support block is not higher than the horizontal height of the SCF sub-mounting groove surface.

[0017] Furthermore, the horizontal height of the support block is consistent with the horizontal height of the SCF sub-mounting groove surface.

[0018] The beneficial effects of this utility model are:

[0019] This invention utilizes four rectangular block supports to conveniently adjust the spacing between the supports according to different sizes of SCF components. Each support has a rectangular SCF mounting slot that engages with the four corners of the SCF component, thus enabling adjustable positioning of SCF components of varying sizes. A positioning structure composed of support blocks and adjusting blocks allows for stable assembly by parallel insertion of the support blocks between any two supports. This ensures that the spacing between the positioning pins on the adjusting blocks and the SCF mounting slots remains constant. This allows for convenient matching of SCF components of different sizes while easily positioning the protective film or release film relative to the SCF component in the mounting slot, facilitating lamination operations and ensuring lamination accuracy. Furthermore, the adjusting structure on the adjusting blocks allows for adjusting the spacing between the supports on both sides of the support block, enabling on-demand adjustment of the spacing between the supports.

[0020] This invention, through the arrangement of a bidirectional lead screw and two positioning plates, can both utilize the rotation of the bidirectional lead screw to drive the two positioning plates to move close together or apart along the slide groove, so as to achieve precise adjustment of the distance between the supports on both sides, and utilize the bidirectional lead screw to drive the two positioning plates to move synchronously, so as to keep the support block always in the middle position of the supports on both sides, ensuring the stability and accuracy of positioning.

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, an embodiment of this utility model provides a bonding fixture for SCF, comprising four rectangular block-shaped supports 1 and a positioning structure 3. Each support 1 is provided with a rectangular SCF sub-mounting groove 2. The four supports 1 can be assembled together to form a rectangular base. The upper end face of the rectangular base is a SCF mounting groove formed by the four SCF sub-mounting grooves 2. The positioning structure 3 includes a support block 31 and an adjusting block 32. The support block 31 is vertically disposed in the middle of the adjusting block 32. The support block 31 and the adjusting block 32 are distributed in a "T" shape. The support block 31 is used to be inserted parallel between any two supports 1. The adjusting block 32 abuts against the side of the support 1 away from the SCF mounting groove. The upper end face of the adjusting block 32 is provided with several positioning pins 4. The adjusting block 32 is also provided with an adjusting structure for adjusting the distance between the supports 1 located on both sides of the support block 31.

[0031] This invention utilizes four rectangular block-shaped supports 1 to conveniently adjust the spacing between the four supports 1 according to SCF components 5 of different sizes. Each support 1 has a rectangular SCF sub-mounting groove 2 that engages with the four corners of the SCF component 5, thus achieving adjustable positioning for SCF components 5 of different sizes. The positioning structure 3, composed of support blocks 31 and adjusting blocks 32, forms a stable combination structure by having support blocks 31 inserted parallel between any two supports 1. This ensures that the spacing between the positioning pins 4 on the adjusting blocks 32 and the SCF mounting groove remains constant. Therefore, it can conveniently match SCF components 5 of different sizes while easily positioning the protective film or release film relative to the SCF component 5 in the SCF mounting groove, facilitating lamination operations and ensuring lamination accuracy. The adjusting structure on the adjusting blocks 32, used to adjust the spacing between the supports 1 located on both sides of the support blocks 31, allows for on-demand adjustment of the spacing between the supports 1 on both sides.

[0032] As attached Figure 4 and attached Figure 5As shown, in another specific embodiment based on the above, the adjustment structure includes a bidirectional lead screw 322 and two positioning plates 324. An adjustment cavity 321 is provided in the adjustment block 32 along the axial direction. The bidirectional lead screw 322 is rotatably arranged in the adjustment cavity 321 along the axial direction. One end of the bidirectional lead screw 322 extends out of the adjustment block 32. The adjustment block 32 is located on the side close to the support block 31 and on the left and right sides of the support block 31. A sliding groove 323 is symmetrically provided about the support block 31 along the axial direction of the adjustment block 32. The two positioning plates 324 extend out of the sliding adjustment block 32 and are arranged in a sliding groove 323. They are both threadedly connected to the bidirectional lead screw 322. The bidirectional lead screw 322 is used to rotate and drive the two positioning plates 324 to move close to or away from each other along the sliding groove 323.

[0033] Thus, by using the bidirectional lead screw 322 and the two positioning plates 324, the bidirectional lead screw 322 can be rotated to drive the two positioning plates 324 to move close to or away from each other along the slide groove 323, so as to achieve precise adjustment of the distance between the supports 1 on both sides. At the same time, the bidirectional lead screw 322 can be used to drive the two positioning plates 324 to move synchronously, so as to keep the support block 31 in the middle position of the supports 1 on both sides at all times, ensuring the stability and accuracy of positioning.

[0034] In a further specific embodiment based on the above, the support block 31 has storage slots 311 on both sides of its end near the adjusting block 32, which communicate with the sliding groove 323 on the same side. The positioning plate 324 can slide along the sliding groove 323 and be stored in the storage slots 311. In this way, by setting the storage slots 311, the positioning plates 324 on both sides can be prevented from affecting the shrinkage of the supports 1 on both sides to the minimum form that fits against the side wall of the support block 31.

[0035] As attached Figure 6 As shown, during use, the supports 1 on both sides can be retracted to fit against the side wall of the support block 31. At this time, the positioning plate 324 is stored in the storage groove 311. The operator can hold the outer side of the supports 1 on both sides with their hands, or use other structures to assist in holding them, to increase the tightness of the fit between the supports 1 and the positioning structure 3. At the same time, the SCF component 5 can also be conveniently held through the side wall of the SCF sub-mounting groove 2 for subsequent film coating.

[0036] As attached Figure 7 As shown, when adjustment is needed, the supports 1 on both sides are pushed by the positioning plate 324 to begin to expand. The operator can hold the outer side of the supports 1 on both sides with their hands, or use other structures to assist in holding them, so that the supports 1 on both sides abut against the positioning plate 324 until the SCF sub-mounting slots 2 on both sides can be used to place the SCF component 5. At this time, the bidirectional screw 322 can be rotated in the opposite direction until the side wall of the SCF sub-mounting slot 2 slightly tightens the SCF component 5 to facilitate subsequent film coating.

[0037] In this design, the two supports 1 that are far from the adjusting block 32 can both provide auxiliary limiting for the SCF component 5 and provide effective support for the bottom of the SCF component 5 when it is being coated.

[0038] In a further specific embodiment based on the above, the width of the positioning plate 324 is consistent with the depth of the storage groove 311 along the axial direction of the adjusting block 32. This ensures complete storage.

[0039] In a further specific embodiment based on the above, a rotating handle 325 is installed at the end of the bidirectional lead screw 322 extending out of the adjusting block 32. The rotating handle 325 is used to conveniently drive the bidirectional lead screw 322 to rotate.

[0040] In a further specific embodiment based on the above, the bidirectional lead screw 322 is rotatably mounted in the adjusting block 32 via bearings. This ensures the stability of the rotation of the bidirectional lead screw 322.

[0041] In a further specific embodiment based on the above, several positioning pins 4 are arranged axially along the adjusting block 32. Thus, during use, the protective film or release film can be aligned and positioned using the positioning pins 4, or precisely positioned using the positioning holes on the protective film or release film. At least two positioning pins 4 are provided to ensure the accuracy of alignment or positioning hole positioning.

[0042] In a further specific embodiment based on the above, the horizontal height of the support block 31 is not higher than the horizontal height of the SCF sub-mounting groove 2, so that the support block 31 does not affect the installation of the SCF component 5. Alternatively, the horizontal height of the support block 31 is the same as the horizontal height of the SCF sub-mounting groove 2, so that the support block 31 can be used to provide auxiliary support for the SCF component 5.
