[0035] Example

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the present embodiment provides a mold for diaphragm bonding, including a bottom plate 10 and a top plate 20, the top surface of the bottom plate 10 is provided with a diaphragm sheet material groove 101, the diaphragm sheet material groove 101 is provided with a plurality of processing stations 102, the top surface of the processing station 102 is provided with a diaphragm contour groove 1021, a front cover contour groove 1022 and a ball top hole 1023 from the outside to the inside, and the ball top hole 1023 is provided through the bottom plate 10; a top pressure groove 201 is provided in the middle of the plate surface of the top plate 20, and a transparent support plate 30 which fits with the top pressure groove 201, a plurality of protrusions 301 which are arranged relative to the plurality of processing stations 102 are provided on the support plate 30, and a plurality of top abutment holes 2011 which are aligned with the plurality of protrusions 301 are provided on the top pressure groove 201.

[0037] In this embodiment, the mold used for bonding the diaphragm needs to bond the front cover and the dome to the diaphragm. The front cover is bonded at the edge of the diaphragm, while the dome is bonded to the middle of the diaphragm. The adhesive is cured by ultraviolet light to complete the bonding.

[0038] Specifically, a front cover is placed on each front cover contour groove 1022 of the bottom plate 10, and the diaphragm adopts a sheet structure on a whole sheet, so it can be placed on the top abutment hole 2011 of the top plate 20 as a whole (because the diaphragm presents a super-convex structure on the sheet, it can be placed in alignment with multiple top abutment holes 2011), so that glue can be applied to the inner side of the diaphragm on the sheet, that is, glue is applied to the positions of the front cover and the ball top hole 1023 corresponding to the diaphragm. Then, when the bottom plate 10 and the top plate 20 are covered, multiple front covers are aligned and covered with multiple diaphragms on the sheet, and preliminary bonding is achieved through the top pressure of the support plate 30. At this time, a ball top can be placed on each diaphragm on the sheet through the ball top hole 1023 on the bottom plate 10, so that the ball top is bonded to the diaphragm. Then, ultraviolet light is passed through the transparent support plate 30 for light curing to complete the bonding of the membrane; and after bonding, the membrane on the sheet is cut off by laser to obtain the desired product after the membrane is bonded, achieving an efficient and precisely aligned bonding effect.

[0039] The support plate 30 may be made of an acrylic plate or glass to achieve light transmittance of the support plate 30 .

[0040] like Figure 2 , Figure 3 and Figure 7As shown, in this embodiment, the bottom plate 10 is provided with a plurality of positioning holes 103 and / or positioning columns 104 on one side of the diaphragm sheet slot 101, and the top plate 20 is provided with a limiting column that is in contact with the positioning hole 103 or a limiting hole 202 that is in contact with the positioning column 104. In order to quickly align and splice, the bottom plate 10 and the top plate 20 are butted together through the positioning holes 103 and the limiting columns, or the positioning columns 104 are butted together with the limiting holes 202, that is, the axial hole method is used for alignment and stacking, which is simple and convenient in operation, and can ensure accurate alignment and improve production efficiency.

[0041] Furthermore, if Figure 7 As shown, in this embodiment, the bottom plate 10 is embedded with a first permanent magnet 105, and the top plate 20 is embedded with a second permanent magnet 203 that is attracted to the first permanent magnet 105. By setting the permanent magnets, a preliminary calibration can be formed, that is, without human eye observation, by using the effect of magnetic attraction, when the top plate 20 is covered on the bottom plate 10, the purpose of automatic alignment is formed, so as to quickly align the insertion and matching between the positioning hole 103 and the limiting column, thereby improving practicality.

[0042] In this embodiment, the top plate 20 and the support plate 30 are integrally formed, or the top plate 20 and the support plate 30 are nested or separately arranged. The top plate 20 and the support plate 30 are integrally made, and the top pressure of the membrane sheet can be performed by the cooperation of the top plate 20 and the bottom plate 10. Alternatively, the top plate 20 and the support plate 30 adopt a separable structure, which is convenient for making the top plate 20 and the support plate 30 with different materials, reducing the difficulty of the manufacturing process, and being more flexible in designing the structure.

[0043] like Figure 2 and Figure 8 As shown, in this embodiment, multiple pairs of alignment structures 302 for alignment and fitting are arranged on the edge along the edge contour between the support plate 30 and the top pressure groove 201. The alignment structure 302 can be a matching structure of an axis hole, or a matching structure of a barb and a slot, or a matching structure of a groove and a protrusion 301, etc. It has a foolproof effect and can improve the accuracy of alignment.

[0044] Furthermore, if Figure 1 , Figure 2 and Figure 8 As shown, in this embodiment, a plurality of threaded holes 303 are further provided on the edge along the edge contour between the support plate 30 and the top pressure groove 201. Through the provision of the threaded holes 303, the support plate 30 can be locked on the top pressure groove 201 by screws, so that the support plate 30 will not fall out of the top pressure groove 201, thereby improving the convenience of the flipping operation of the top plate 20.

[0045] like Figure 8As shown, in this embodiment, a plurality of air holes 304 penetrating the support plate 30 are provided on the protrusion 301. The provision of the air holes 304 ensures that when the top plate 20 is covered with the top plate 20, no air pressure is generated between the processing station 102 and the protrusion 301 (because the diaphragm is thin and a higher atmospheric pressure is generated when the diaphragm is assembled at a faster speed), thereby avoiding damage to the diaphragm. The provision of the air holes 304 can realize a fast assembly operation, reduce the difficulty of the operation, and improve practicality.

[0046] like Figure 4 and Figure 5 As shown, in this embodiment, a plurality of magnetic blocks 1024 and ejection holes 1025 are provided at the relative positions of the front cover contour groove 1022 and the front cover. The magnetic blocks 1024 can be permanent magnets, which can adsorb the front cover so that the front cover will not be offset during bonding, thereby improving the production quality. The design of the ejection hole 1025 allows the diaphragm that has been bonded and cut to be ejected from the processing station 102 by passing the shaft through the ejection hole 1025, making it easy to take; and the position of the ejection is the front cover, which will not cause damage to the diaphragm, reducing the difficulty of the ejection operation and improving practicality.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
