Description

Technical Field

[0001] The utility model relates to the field of Mylar sheets, and more specifically to an insulating Mylar sheet for electronic component assembly. Background Art

[0002] Mylar film is a film made by heating dimethyl terephthalate and ethylene glycol with the assistance of relevant catalysts, undergoing ester exchange and vacuum polycondensation, and biaxial stretching. It has dimensional stability, flatness, excellent tear strength, heat resistance, cold resistance, moisture resistance, water resistance, chemical corrosion resistance, and super insulation performance, excellent electrical, mechanical, heat resistance, and chemical resistance. It is now widely used in the electrical insulation industry and is suitable for gaskets, baffles, screens and protection for electronics, household appliances, instruments, displays, motor slots, computers and peripheral equipment.

[0003] When Mylar sheets are used as gaskets when combining two electronic components, glue is often applied to the end faces of the Mylar sheets and then bonded to the surface of the electronic components. Once the bonding position of the Mylar sheets is inaccurate due to negligence during the bonding process, a large force is required to separate the bonded Mylar sheets from the electronic components and reinstall them. Traditional Mylar sheets require workers to bond them in place at one time, which is prone to mistakes and the bonding process is more laborious and stressful.

[0004] Therefore, a new solution needs to be proposed to solve the problem that the Mylar sheet can only be bonded into place once and is difficult to modify during the bonding process. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide an insulating Mylar sheet for electronic component assembly, which has the advantage of conveniently correcting the bonding angle of the Mylar sheet during the bonding process.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an insulating Mylar sheet for electronic component assembly, comprising a Mylar sheet body, a bonding assembly slidably connected to the center of the lower end surface of the Mylar sheet body, the bonding assembly comprising a plurality of bonding parts slidably connected to each other, the bonding parts are arranged in a direction away from the Mylar sheet body, a positioning pin is slidably connected to the center of the bonding part farthest from the Mylar sheet body, and the bonding parts divide a large bonding surface of the entire Mylar sheet body and the electronic component into a plurality of small bonding surfaces.

[0007] The utility model is further configured as follows: a first sliding groove is provided on the lower end surface of the Mylar sheet body and on the end surfaces of each adhesive component away from the Mylar sheet body.

[0008] The utility model is further configured as follows: the groove depth of the first sliding groove is equal to the thickness of the adjacent adhesive member.

[0009] The utility model is further configured as follows: the adhesive component includes an extrusion plate, and an end of the extrusion plate away from the Mylar sheet body is fixedly connected to an annular wall, and the annular wall is used to enclose a first sliding groove. A plurality of glue outlet holes are provided on the extrusion plate located outside the annular wall and on the annular wall away from the extrusion plate, and the shape of the extrusion plate is consistent with the groove surface shape of the first sliding groove.

[0010] The utility model is further configured as follows: the end surface of the extrusion disk facing the Mylar sheet body and the bottom of the first sliding groove are both bonded with a rubber film.

[0011] The utility model is further configured as follows: the diaphragm is made of polytetrafluoroethylene polymer material.

[0012] The utility model is further configured as follows: the cross section of the positioning pin is circular.

[0013] The utility model is further configured as follows: glue injection holes are provided at the centers of the Mylar sheet body and the bonding component.

[0014] In summary, the utility model has the following beneficial effects: the utility model divides a large bonding surface of the entire Mylar sheet body and the electronic component into a plurality of small bonding surfaces by providing an adhesive part at the bottom end of the Mylar sheet body, so that in the process of bonding the Mylar sheet, the bonding area increases from small to large, and the bonding angle can be modified in real time during the bonding process, avoiding the difficulty of secondary correction due to deviation found after one-time complete bonding, and reducing the energy consumption of workers compared with the method of bonding the complete Mylar sheet in one go.

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment: Insulating Mylar sheet for electronic component assembly, such as Figure 1 , Figure 2As shown, it includes a Mylar sheet body 1, and an adhesive component 2 is slidably connected at the center of the lower end of the Mylar sheet body 1. The adhesive component 2 includes a plurality of adhesive members 22 slidably connected to each other. The adhesive members 22 are arranged in a direction away from the Mylar sheet body 1. A positioning pin 3 is slidably connected at the center of the adhesive member 22 farthest from the Mylar sheet body 1. The cross-section of the positioning pin 3 is circular. The circular positioning pin 3 is convenient for allowing the Mylar sheet body 1 to rotate relative to the positioning pin 3 to adjust the bonding position after displacement. The lower end surface of the Mylar sheet body 1 and the end surface of each adhesive member 22 away from the Mylar sheet body 1 are provided with a first sliding groove 23. The sliding connection between the adhesive member 22 and the Mylar sheet body 1 and the sliding connection between the adhesive members 22 and the adhesive members 22 are realized by the provision of the first sliding groove 23. A glue injection hole 11 is provided at the center of the Mylar sheet body 1 and the adhesive component 2. The glue injection hole 11 passes through All the first sliding grooves 23, the groove depth of the first sliding grooves 23 is equal to the thickness of the adhesive 22 located in the adjacent first sliding grooves 23. The purpose of this structure is to make all the adhesives 22 flush with the end faces of the Mylar sheet body 1 after the utility model is completely bonded to the electronic component, thereby increasing the bonding flatness of the Mylar sheet. The farther away the adhesive 22 from the Mylar sheet body 1 is, the smaller the friction between the first sliding groove 23 is. The design of this structure is that when using the utility model, glue is first injected into the first sliding groove 23 through the glue injection hole 11, and then the positioning pin 3 is used for preliminary positioning. After positioning, the Mylar sheet body 1 located at the uppermost end is squeezed to drive the adhesive 22 closest to the positioning pin 3 to fit with the electronic component one by one, thereby increasing the bonding area of ​​the utility model and the electronic component in turn, reducing the force required for separation after the Mylar sheet body 1 is found to be offset, and facilitating adjustment.

[0020] like Figure 1 , Figure 2As shown, the adhesive 22 includes an extrusion disc 221 with a circular cross section, and an annular wall 222 is fixedly connected to one end of the extrusion disc 221 away from the mylar sheet body 1, and the annular wall 222 surrounds the first sliding groove 23. A plurality of glue outlet holes 21 are provided on the extrusion disc 221 located outside the annular wall 222 and on the annular wall 222 away from the extrusion disc 221. The shape of the extrusion disc 221 is consistent with the groove surface shape of the first sliding groove 23. When the adhesive 22 slides in the first sliding groove 23, the glue injected into the first sliding groove 23 can be squeezed through the extrusion disc 221, and the glue is squeezed from the glue outlet holes 21 to the adhesive 2 2, to avoid the glue being applied to the end surface of the Mylar sheet body 1, which will affect the viscosity of the glue due to the touch of human hands. This structure facilitates the bonding of the pressed glue piece to the electronic component while avoiding the influence on the viscosity of the glue. The end surface of the extrusion disk 221 facing the Mylar sheet body 1 and the bottom of the first sliding groove 23 are both bonded with a diaphragm. The diaphragm is made of polytetrafluoroethylene polymer material. The surface of polytetrafluoroethylene is extremely smooth, and its surface tension is smaller than that of water. It is difficult for glue to adhere to its surface. The diaphragm of this material prevents the glue from solidifying in the first sliding groove 23, causing waste of glue and affecting the use of the Mylar sheet.

[0021] Working principle: Glue is injected into the first sliding groove 23 along the glue injection part, and initially positioned by the positioning pin 3 placed at the lowest end, and then force is applied to the Mylar sheet in the bonding direction. Since the friction between the lowest adhesive part 22 and the first sliding groove 23 is the smallest, the lowest adhesive part 22 first adheres to the surface of the electronic component, and then the upper adhesive parts 22 adhere to the surface of the electronic component in turn. In this process, the extrusion disk 221 squeezes the glue in the first sliding groove 23 and squeezes it out of the glue outlet 21, so that the glue is located on the lower end surface of the Mylar sheet body 1 and the adhesive part 22. At the same time, a polytetrafluoroethylene diaphragm is used to prevent the glue from being bonded in the first sliding groove 23 and not overflowing from the glue outlet 21. By gradually increasing the bonding area between the utility model and the electronic component, the problem of inconvenience in secondary adjustment after one-time bonding is avoided, the concentration and mental strength required by the workers in the bonding process are reduced, and the work efficiency of the workers is improved.

[0022] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
