Description

Technical Field

[0001] This invention relates to the field of dispensing device technology, and more particularly to a small-gap adhesive layer control structure. Background Technology

[0002] In the assembly of certain small components or parts, it is necessary to bond the parts within a small gap, with a thin adhesive layer, and a certain pre-pressure is required during bonding. Existing dispensing devices or structures are mostly used to drip adhesive into the corresponding structure without considering pre-pressure or other requirements. They are often used for positioning and fixing structural components, with no strict control requirements on adhesive layer thickness or the relative position after bonding.

[0003] Encapsulating or sealing adhesives are mostly fluid or semi-fluid. Traditional bonding methods include two approaches: one is to directly apply the adhesive to the mating surfaces of the components to be joined and then directly bond the adhered surfaces; the other is to pot the required adhesive between the components. Both methods achieve the connection after the adhesive has cured, but are mostly used with semi-fluid or non-fluid adhesives. To ensure a good bonding effect, a certain pre-pressure is generally required. Traditional dispensing devices or structures do not consider the control of adhesive layer thickness and the implementation of adhesive pre-pressure. Due to limitations in the dispensing structure or component structure, they cannot control the adhesive thickness, especially when the adhesive layer is thin.

[0004] Therefore, it is necessary to develop a small-gap adhesive layer control structure to solve the above problems. Summary of the Invention

[0046] like Figure 1-16 As shown, a small-gap adhesive layer control structure includes:

[0047] Fixed column 5; Fixed column 5 includes upper connector 51, two connecting plates 52, and lower connector 53. The upper connector 51 and lower connector 53 are arranged in parallel. The side of the upper connector 51 and the side of the lower connector 53 are connected by two oppositely arranged connecting plates 52. The upper connector 51 and lower connector 53 are arranged on the same axis.

[0052] At least one gasket; the gasket is placed between the upper fixed transition member 7 and the upper connecting member 51, or between the lower fixed transition member 9 and the lower connecting member 53.

[0053] In some embodiments, the small-gap adhesive layer control structure further includes an upper fixed left member 1, an upper fixed right member 2, a lower fixed left member 3, and a lower fixed right member 4 of the same structural size. The upper fixed left member 1 and the upper fixed right member 2 each have a V-groove in the middle and connecting ears protruding from both sides. Each connecting ear has a connecting hole. Bolts pass through the connecting holes for radial connection between the upper fixed left member 1 and the upper fixed right member 2. The upper fixed left member 1 and the upper fixed right member 2 are fitted onto the upper fixed transition member 7 and the first sub-member 8 via the V-groove. On the side wall, the outer diameter of the upper fixed transition piece 7 and the first sub-piece 8 is the same; the middle of the lower fixed left piece 3 and the lower fixed right piece 4 are both provided with V-shaped grooves, and the two sides are both provided with connecting ears. The connecting ears are provided with connecting holes. After the bolt passes through the connecting holes, it is used for the radial connection of the lower fixed left piece 3 and the lower fixed right piece 4. The lower fixed left piece 3 and the lower fixed right piece 4 are fitted onto the side wall of the lower fixed transition piece 9 and the second sub-piece 10 through the V-shaped grooves. The outer diameter of the lower fixed transition piece 9 and the second sub-piece 10 is the same.

[0054] In some embodiments, a connecting groove is formed at the upper end of the second component 10, and a protrusion is formed at the lower end of the first component 8, with the protrusion disposed within the connecting groove.

[0055] In some embodiments, the upper end of the upper connector 51 is provided with a first groove, the bottom center of the first groove is provided with a first through hole, and the bottom of the first groove is provided with a plurality of first screw holes around the first through hole. The upper diameter of the upper fixing transition member 7 is larger than the lower diameter. The upper end of the upper fixing transition member 7 is placed in the first groove, and the lower end of the upper fixing transition member 7 passes through the first through hole. The upper end of the upper fixing transition member 7 is provided with a plurality of first through holes vertically. A plurality of fastening screws 6 pass through the plurality of first through holes and are screwed into the plurality of first screw holes for connecting the upper end of the upper fixing transition member 7 with the upper connector 51.

[0056] In some embodiments, a second groove is vertically provided at the center of the upper fixed transition member 7, a second through hole is provided at the bottom of the second groove, and a second screw hole is provided at the upper end of the first sub-part 8. A connecting bolt passes through the second through hole and is screwed into the second screw hole for connecting the upper fixed transition member 7 and the first sub-part 8.

[0057] In some embodiments, a third through hole is provided in the middle of the lower connector 53, and a plurality of third screw holes are also provided around the third through hole on the lower connector 53. The upper diameter of the lower fixing transition member 9 is smaller than the lower diameter, and the upper end of the lower fixing transition member 9 passes through the third through hole upward. A plurality of fourth through holes are provided at the lower end of the lower fixing transition member 9, and a plurality of fastening screws 6 pass through the plurality of fourth through holes and are screwed into the plurality of third screw holes for connecting the lower end of the lower fixing transition member 9 with the lower connector 53.

[0058] In some embodiments, a fifth through hole is axially provided at the center of the lower fixed transition member 9, and a fourth screw hole is axially provided at the center of the second sub-part 10. The connecting bolt passes through the fifth through hole and is screwed into the fourth screw hole for connecting the upper end of the lower fixed transition member 9 with the lower end of the second sub-part 10.

[0059] When the bottom of the second component 10 is fixed to the lower fixed transition component 9, it needs to be assisted by the lower fixed left component 3 and the lower fixed right component 4: the lower fixed left component 3 and the lower fixed right component 4 are respectively designed with V-shaped structures, and the outer surfaces of the second component 10 and the lower fixed block transition component are designed with cylindrical surfaces. The lower fixed transition block and the second component 10 are placed between the lower fixed left component 3 and the lower fixed right component 4. The V-shaped structure surfaces on the lower fixed left component 3 and the lower fixed right component 4 cooperate with the cylindrical surfaces on the second component 10 and the lower fixed transition block for positioning, so as to achieve coaxial positioning of the lower fixed transition block and the second component 10.

[0060] When the bottom of the first component 8 is fixed to the upper fixed transition component 7, it needs to be assisted by the upper fixed left component 1 and the upper fixed right component 2: the upper fixed left component and the upper fixed right component are respectively designed with V-shaped structures, and the outer surfaces of the first component 8 and the upper fixed transition component are designed with cylindrical surfaces. The upper fixed transition block and the first component 8 are placed between the upper fixed left component 1 and the upper fixed right component 2. The V-shaped structure surfaces on the upper fixed left component and the upper fixed right component cooperate with the cylindrical surfaces on the first component 8 and the upper fixed transition block for positioning, so as to achieve coaxial positioning of the upper fixed transition block and the first component 8.

[0061] The connection between the upper fixed transition piece 7 and the upper connecting piece 51, the connection between the upper fixed transition piece 7 and the first sub-piece 8, the connection between the lower fixed transition piece 9 and the lower connecting piece 53, and the connection between the lower fixed transition piece 9 and the second sub-piece 10, achieve a certain pre-pressure on the adhesive layer, providing the necessary pre-pressure for sealing. As needed, a corresponding load can be superimposed on the center position of the upper fixed transition piece 7 and the lower fixed transition piece 9 to achieve the required pre-pressure.

[0062] The lower surface of the first component 8 and the upper surface of the second component 10 are designed with corresponding concave and convex structures. These structures cooperate, and adhesive is filled into the gaps between them to achieve bonding between the first component 8 and the second component 10. The concave and convex structures are used to store the adhesive. By controlling the distance between the first component 8 and the second component 10, the adhesive thickness can be controlled. When a larger distance and a thicker adhesive layer are required, shims can be added between the connection between the upper fixed transition piece 7 and the upper connecting piece 51, or between the connection between the lower fixed transition piece 9 and the lower connecting piece 53, to adjust the distance and achieve the corresponding adhesive layer thickness.

[0063] Because the gap between the first component 8 and the second component 10 is relatively small, especially when it is less than mm, in order to ensure the existence and confirmation of the gap, one of the upper fixed transition component 7 and the lower fixed transition component 9 is designed to be metal and the other is designed to be non-metallic. After the connection and sealing are fixed, the electrical characteristics between the upper fixed transition component 7 and the lower fixed transition component 9 are tested to further determine the existence of the gap between the first component 8 and the second component 10, thereby achieving the effectiveness of thinner adhesive layer control.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
