Description

Technical Field

[0001] This utility model relates to the field of assembling waterproof membranes for car doors, and more specifically, to a tool for assembling waterproof membranes for car doors. Background Technology

[0002] For commercial vehicle doors, the need to integrate components such as window regulators and speakers necessitates wiring, requiring pre-drilled holes for various products and processes on the inner door panel. To prevent rainwater from entering the cab through the gap between the window glass and the outer window seals, the inner door panel needs to be waterproofed. Waterproof membranes are a relatively common and widely used waterproofing structure.

[0003] Car door waterproofing membranes are typically composed of a PE film and butyl sealant or foam double-sided adhesive. The workability of butyl sealant or foam adhesive is closely related to the assembly environment temperature; the lower the temperature, the higher the viscosity and the worse the adhesion. Therefore, in workshops without a constant temperature environment, the proportion of water seepage into the waterproofing membrane is often relatively high in winter. Maintaining a constant temperature environment requires a high initial investment and daily energy consumption, necessitating research into relevant assembly tools to achieve high-quality adhesion and sealing. Utility Model Content

[0039] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Example 1

[0041] A car door waterproof membrane is a thin film or adhesive material installed on the inside of the car door. It is mainly used to prevent moisture, dust and other external environmental factors from penetrating the internal structure of the car door (such as wiring and metal parts). It also has functions such as sound insulation and heat insulation. Its core function is to protect the internal components of the car door from moisture and corrosion and extend its service life.

[0042] Reference Figure 1 and Figure 2 This embodiment provides a door waterproof membrane assembly tool, including:

[0043] Handle 8;

[0044] The housing 10 has one end connected to the handle 8 and the other end having a receiving groove 1011.

[0045] Roller 1, the roller 1 is mounted in the receiving groove 1011 via roller 1 shaft, and a portion of the roller 1 is located outside the receiving groove 1011;

[0046] Heating unit 2 is disposed in the receiving groove 1011 and is used to heat the roller 1;

[0047] A temperature control unit is electrically connected to the heating unit 2 and is used to control the heating temperature.

[0048] The handle 8 can be made of plastic, metal or wood.

[0049] In this embodiment, in order to improve the heating effect on the roller 1, a heat insulation material 4 is provided on the inner side of the heat radiation structure 3 (i.e., between the shell 10 and the heat radiation structure 3). The heat insulation material 4 can be glass wool.

[0050] Specifically, heating units 2 are respectively provided on both sides of the roller 1. The heating units 2 can be heating plates, which can be made of high-resistivity alloy wire and insulating material. The heat radiation structure 3 is provided on the inner side of the heating unit 2. The heat radiation structure 3 is made of stainless steel plate, and its size covers 2 / 3 of the area of ​​the roller 1. The heat radiation structure 3 is provided on the inner side of the heat insulation material 4, which is made of glass wool.

[0051] Specifically, the temperature control unit includes a temperature control circuit board and a temperature control knob 6. The temperature control unit is also connected to a power cord 9. The temperature control unit and the indicator light are respectively located on the handle 8. The heating unit 2 and the temperature control unit form a temperature control circuit. The temperature control circuit also includes a switch 7 to control the opening and closing of the entire circuit and an indicator light to display the power-on status. The heating temperature is adjusted by turning the temperature control knob 6, controlling the temperature range of the heating unit 2 between 60℃ and 150℃.

[0052] In this embodiment, the outer wall of the roller 1 has multiple annular grooves 103 sequentially formed along its width to create a corrugated structure. The corrugated structure on the outer wall of the roller 1 (i.e., the roller surface) and its built-in heating function overcome the problem of poor low-temperature workability of the door waterproof membrane, and also increases the viscosity of the door waterproof membrane, allowing the butyl rubber or foam double-sided adhesive of the door waterproof membrane to effectively wet and bond to the sheet metal surface, achieving efficient and high-quality production and assembly of the door waterproof membrane at low cost.

[0053] In this embodiment, the diameter of the roller 1 ranges from 50mm to 70mm, and the width ranges from 8mm to 12mm;

[0054] The roller 1 has three annular grooves 103, and the rolling surface of the roller 1 forms four peaks and three troughs. The groove depth of the annular grooves 103 is 1 mm, that is, the depth of the troughs is 1 mm. A rounded corner is provided on both sides of the peak, and the radius of the rounded corner is 0.5 mm.

[0055] The roller 1 adopts a lightweight design. The roller 1 has a shaft hole 101 along its axial direction. The roller 1 has a plurality of weight-reducing holes 102 evenly distributed around its axial direction. There are 8 weight-reducing holes 102 evenly distributed. The diameter of the weight-reducing holes 102 can be designed to be 10mm.

[0056] A heat insulation plate 5 is also provided between the housing 10 and the handle 8 to prevent the heat from the heating unit 2 from being transferred to the handle 8 and burning the hand when the handle 8 is held.

[0057] Preferably, the heat insulation board 5 is a round plate with a thickness ranging from 2mm to 4mm and a diameter ranging from 80mm to 120mm. The material of the heat insulation board 5 can be phenolic foam board or fiberglass board.

[0058] Roller 1 can be made of stainless steel.

[0059] The length of the entire door waterproof membrane assembly tool is designed to be between 150mm and 200mm, and its total weight is designed to be less than 0.35kg.

[0060] In actual use, this door waterproof membrane assembly tool:

[0061] The operator holds handle 8 and applies slight pressure along the adhesive line of the waterproof membrane on the car door, rolling it through roller 1. While rolling, heating unit 2 heats roller 1 to increase its temperature. When roller 1 contacts the waterproof membrane, it also heats the membrane to increase its viscosity. Rolling can be repeated multiple times within a certain length as needed. Rolling roller 1 around the adhesive line of the waterproof membrane creates an indentation in the width of the membrane. This bonding method, which heats the membrane while rolling, increases the viscosity of the waterproof membrane, achieving high-quality bonding and assembly, and improving the sealing performance after assembly.

[0062] Example 2

[0063] This embodiment provides a specific implementation method for assembling a waterproof membrane for a car door:

[0064] See Figure 1First, connect the power cord 9, turn on the switch 7, and set the heating temperature of the heating unit 2 to 80℃ using the temperature control knob 6. Hold the wooden handle 8 and roll it along the adhesive line of the waterproof membrane on the car door with slight force. Roll back and forth at least twice within a 200mm length as needed. The roller 1 has a corrugated surface and is 10mm wide. Roll the roller 1 around the adhesive line of the waterproof membrane on the car door, and finally form a wavy indentation in the width direction of the butyl rubber (waterproof membrane on the car door).

[0065] The beneficial effects of the technical solution of this utility model are:

[0066] 1. This application provides a tool for assembling a car door waterproof membrane. In actual use, the operator holds the handle 8 and applies slight force along the adhesive line of the car door waterproof membrane to roll it through the roller 1. While rolling, the heating unit 2 heats the roller 1 to increase its temperature. When the roller 1 contacts the car door waterproof membrane, it can also heat the membrane to increase its viscosity. The roller 1 can be rolled back and forth multiple times within a certain length as needed. The roller 1 is used to roll around the adhesive line of the car door waterproof membrane, eventually forming an indentation in the width direction of the waterproof membrane. This bonding method, which heats the waterproof membrane while rolling, increases the viscosity of the car door waterproof membrane, achieves high-quality bonding and assembly of the car door waterproof membrane, and improves the sealing performance after assembly.

[0067] 2. The roller has a corrugated surface design and a built-in heating function, which overcomes the problem of poor low-temperature construction of the door waterproof membrane. This allows the butyl rubber or foam double-sided adhesive of the door waterproof membrane to effectively wet and bond to the sheet metal surface, achieving efficient and high-quality production and assembly of the door waterproof membrane at low cost.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
