Description

Technical Field

[0001] The invention relates to the technical field of surface processing of steel belt clamps for electric vehicles, and in particular to a method for processing a steel belt surface connected with an insulating soft film. Background Art

[0002] The battery clamp of an electric vehicle plays the role of fastening the battery. Since the battery has a heat dissipation effect during use, the battery clamp made by sticking Teflon insulating film on the clamp has high temperature resistance. The Chinese patent with the authorization announcement number CN216335741U discloses an automatic tape sticking machine for a battery clamp. Although it can realize the automatic sticking and cutting of the tape on the steel belt clamp, the tape can only cover a small area on the surface of the steel belt because the lead-out direction of the tape is perpendicular to the direction of the steel belt, resulting in the limited high temperature resistance of the Teflon tape on the steel belt. If it is necessary to wrap the tape (Teflon insulating film) in the same direction as the steel belt, the tape can cover a larger area on the surface of the steel belt. However, this wrapping method does not have a processing positioning tooling or auxiliary device adapted to it in the prior art, and it needs to rely solely on manual wrapping operations, which is difficult to operate and has low processing accuracy. Therefore, there is an urgent need to provide a positioning method for connecting the insulating film on the surface of a steel strip, which can efficiently cover the Teflon insulating film on the surface of the steel strip in the same direction, improve processing accuracy, and improve processing efficiency.

[0012] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0013] Please refer to Figures 1 to 8 The specific embodiment of the present invention relates to a method for processing a steel strip surface connected with an insulating film, based on a processing device, the processing device comprising: Rack 1; A support base 2, the support base 2 is connected to the frame 1, the upper surface 21 of the support base 2 is a horizontal plane, and the two sides of the support base 2 along the Y direction are respectively provided with mutually symmetrical guide parts 22, and the guide parts 22 include a first inclined surface 221, a vertical surface 222 and a second inclined surface 223 arranged in sequence from top to bottom, and the distance between the vertical surfaces 222 of the two guide parts 22 is greater than the width of the upper surface 21 of the support base 2; The pressing assembly 3, two groups of pressing assemblies 3 are symmetrically arranged on both sides of the support seat 2 along the Y direction; the pressing assembly 3 includes a lifting seat 31, a lifting drive member 32, a pressure roller assembly and an elastic member 35; the lifting seat 31 is liftably connected to the frame 1 through the lifting drive member 32, and a limiting groove is provided on the upper part of the lifting seat 31 facing the side of the support seat 2, and the limiting groove is a straight inner angle groove 36 formed by a positioning plane 361 and a positioning side surface 362, and the inner angle spacing of the straight inner angle grooves 36 of the two pressing assemblies 3 is equal to the width of the insulating film; the pressure roller assembly is located below the limiting groove, and the pressure roller assembly includes a pressure roller frame 34 and a pressure roller body 33 rotatably connected to the pressure roller frame 34, the axial direction of the pressure roller body 33 is the X direction, and the pressure roller frame 34 is connected to the lifting seat 31 through an elastic member 35, and the elastic direction of the elastic member 35 is the Y direction; The processing method comprises the following steps: S1: Control the lifting drive member 32 to drive the lifting seat 31 to move to the first state, so that the positioning plane 361 of the lifting seat 31 is flush with the upper surface 21 of the support seat 2. At this time, the pressure roller body 33 is pressed against the second inclined surface 223 under the action of the elastic member 35; In this step, the elastic member 35, ie, the spring, is in a compressed state.

[0014] S2: Cut the Teflon tape after it is drawn out to a fixed length to form a Teflon insulating film 4, and place the Teflon insulating film 4 on the upper surface 21 of the support seat 2 so that the side edge of the insulating film is limited by the positioning side surface 362; S3: placing the steel strip body 5 on the surface of the middle part of the Teflon insulating film 4, and positioning the two ends of the steel strip body 5 so that the side edge of the steel strip body 5 and the vertical surface 222 of the guide portion 22 are located in the same vertical plane; In this step, both ends of the steel strip need to be positioned manually or with the aid of other positioning means to avoid displacement of the steel strip during subsequent processing.

[0015] S4: Control the lifting drive member 32 to drive the lifting seat 31 to move upward, so that the pressing roller body 33 rolls to press against the upper part of the Teflon insulating film 4 and the steel belt body 5, and lasts for 20-40 seconds, so that the Teflon insulating film 4 is attached to the surface of the steel belt body 5; In this step, it should be noted that Figure 6 The radius of the pressure roller body 33 is greater than the distance between the vertical surface 222 and the side of the steel strip, so that the pressure roller body 33 will not be stuck on the vertical surface 222 and the side of the steel strip body 5 during the process of rising with the lifting seat 31. The pressure roller body 33 will roll along the second inclined surface 223 to the vertical surface 222 and the side of the steel strip body 5 during the process of rising with the lifting seat 31. Since the side of the steel strip body 5 and the vertical surface 222 are located in the same plane, the pressure roller body 33 will guide the side of the Teflon insulating film 4 upward and press it against the upper surface 21 of the steel strip body 5. Figure 7 Since the spring itself also has radial elasticity, under its elastic action, the pressure roller body 33 also has downward pressure, so that during the movement and the stay period of 20-40 seconds, the edge of the Teflon insulating film 4 is pressed downward against the upper part of the steel belt body 5.

[0016] S5: The steel strip body 5 is pulled out from one end to complete the processing. At this time, the pressing roller body 33 is pressed against the position between the first inclined surface 221 and the upper surface 21 of the support seat 2; In this step, when the steel strip body 5 is pulled out from one end, the pressure and friction of the pressure roller body 33 can be used to make the Teflon insulating film 4 more closely adhere to the surface of the steel strip. Figure 8 , the pressing roller body 33 directly returns to the position between the first inclined surface 221 and the upper surface 21 of the support seat 2 under the action of the spring; S6: Control the lifting drive member 32 to drive the lifting seat 31 to move downward to the first state. During this process, the pressure roller body 33 rolls along the first inclined surface 221 and the vertical surface 222 under the action of the elastic member 35 until it is pressed against the second inclined surface 223; In this step, when the lifting seat 31 descends, the pressing roller body 33 will return to the first state under the guidance of the first inclined surface 221 and the vertical surface 222 under the action of the spring, so as to facilitate the continuous processing of the next steel strip body 5; Repeat the above steps S1 to S6.

[0017] In the above implementation manner, by designing a processing device with a specific structure and combining it with a specific processing method, it is only necessary to manually position and place the Teflon insulating film 4 and the steel belt in sequence, and the processing device can be used to complete the stable and efficient attachment of the Teflon insulating film 4 to the surface of the steel belt. Since the Teflon insulating film 4 and the steel belt are attached in the same direction, the Teflon insulating film 4 can quickly cover a larger area of ​​the surface of the steel belt. The above processing device has low cost and only needs to control a group of lifting drive parts 32 to lift according to a specific stroke. It does not require a complex control program and a complex drive structure. The above processing method is simple to operate, efficient, and has high processing accuracy.

[0018] As a preferred embodiment, the lifting drive member 32 is a cylinder, a hydraulic cylinder, an electric cylinder or a screw guide assembly, preferably a cylinder.

[0019] As a preferred embodiment, the pressing roller body 33 is an electromagnetic heating roller, and the surface temperature of the pressing roller body 33 is controlled at 50-55°C.

[0020] In the above embodiment, the electromagnetic heating roller is a prior art, and its principle will not be elaborated here. Through electromagnetic heating, the surface temperature of the pressure roller body 33 is controlled at 50-55°C, so that when it contacts the edge of the Teflon insulating film 4 and when it is pressed against the upper surface 21 of the steel belt body 5, it can properly heat the Teflon insulating film 4, so that the edge of the Teflon insulating film 4 is heated and properly softened, and better adhered to the surface of the steel belt body 5.

[0021] As a preferred embodiment, a heating plate is provided on the upper surface 21 of the support base 2, and the heating temperature of the heating plate is 40-45°C.

[0022] In the above embodiment, a heating plate is arranged on the upper surface 21 of the support seat 2 to heat the middle part of the Teflon insulating film 4, so that the middle part of the Teflon insulating film 4 is heated and appropriately softened, and better adhered to the lower surface of the steel belt body 5. Since the contact time between the heating plate and the Teflon insulating film 4 is longer, the temperature should not be too high and lower than the temperature of the surface of the pressure roller body 33.

[0023] As a preferred embodiment, the positioning side surface 362 is an inclined surface, which facilitates the positioning and insertion of the Teflon insulating film 4.

[0024] As a preferred embodiment, the elastic member 35 includes a plurality of springs arranged between the pressure roller frame 34 and the lifting seat 31 , and the axial direction of the springs is the Y direction.

[0025] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
