Description

Technical Field

[0001] This invention belongs to the field of positioning mechanism technology, and specifically relates to a precise positioning mechanism for insulating film. Background Technology

[0002] An insulating film is a thin film that ensures good electrical insulation. This film should have a high resistivity (above 10¹⁰ Ω·cm) and a high breakdown field strength, while its electronic structure is characterized by a large bandgap. For high-frequency insulation, the material also needs to have low dielectric loss.

[0003] Insulating film is used in the outer packaging of many products to provide protection. When using insulating film, since it is mostly wound on a roller, the operator pulls the film to unwind the roller and obtain a certain length of insulating film. However, if the operator uses too much force, the roller may rotate too many times, causing the insulating film to be unwound to an excessive length, resulting in redundant accumulation and hindering normal production. Summary of the Invention

[0004] In view of the problems raised in the background art above, the purpose of the present invention is to provide a mechanism for precise positioning of insulating film.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] An insulating film positioning precision mechanism includes a programmable logic controller, a material roller for winding the insulating film, a first rotating roller and a second rotating roller for limiting the movement trajectory of the insulating film, a positioning cylinder for positioning the position of the insulating film, and an abutment plate that cooperates with the positioning cylinder.

[0007] The material roller has rotational freedom for winding and unwinding;

[0008] An encoder is connected to the rotating end of the first rotating roller;

[0009] The first rotating roller is located between the material roller and the second rotating roller. The axial height of the first rotating roller is lower than the axial height of the first rotating roller and the second rotating roller. The first rotating roller shapes the trajectory of the insulating film flowing through it into a V shape.

[0010] The output end of the positioning cylinder comes into contact with the contact plate, clamping the insulating film.

[0011] Furthermore, the output end of the positioning cylinder is connected to the first pressure plate, and the lower surface of the first pressure plate is provided with several rubber contacts. This structural design allows the flexible characteristics of the rubber contacts to prevent damage to the insulating film when pressed down.

[0012] Furthermore, the shaft of the material roller is connected to the motor. With this structural design, the motor can both wind up the insulating film and prevent the insulating film on the material roller from continuously unwinding due to inertia by applying a torque in the opposite direction to the unwinding.

[0013] Furthermore, it also includes a cutting cylinder for cutting the insulating film, the output end of which is connected to a second pressure plate, and the lower surface of the second pressure plate is connected to a cutting blade. With this structural design, the cutting cylinder causes the cutting blade to move downward, thereby cutting the insulating film.

[0014] Furthermore, the upper surface of the contact plate is provided with a cutting groove adapted to the shape of the cutting blade at the position corresponding to the cutting blade. With this structural design, the cutting blade penetrates deep into the cutting groove, thereby causing the insulating film to sink and deform at the position of the cutting groove, resulting in breakage and making the cutting more reliable.

[0015] Furthermore, the cutter has a triangular cross-sectional shape and rounded edges. This structural design, with rounded edges, makes it safer to use.

[0016] Furthermore, the upper surface of the contact plate is provided with a hemispherical cylindrical film-taking groove, which is located between the pressing point of the positioning cylinder and the cutting point of the cutting cylinder. With this structural design, after the cutting is completed, the film-taking groove makes it convenient for the operator to re-hold the insulating film and pull the material roller to unwind. The operator puts his palm into the film-taking groove and moves the insulating film out along the inner wall of the film-taking groove, exposing the end of the insulating film to the outside. The operator pulls the insulating film by pinching the end of the insulating film.

[0017] Further, it includes an emergency stop button for controlling the positioning cylinder and cutting off the cylinder in an emergency. This structural design allows the operator to stop the operation of each component by pressing the emergency stop button in case of an accident, in order to prevent the situation from escalating.

[0018] Furthermore, an obstruction sensor is arranged along the downward spatial path of the cut-off cylinder. When the obstruction sensor is triggered, the downward air intake of the cut-off cylinder is cut off. With this structural design, when the worker's hand crosses the space below the cut-off cylinder to grasp the insulating film, the obstruction sensor is triggered, and the cut-off cylinder will not descend, thus ensuring the safety of the worker.

[0019] Further defined, it includes a bracket for supporting the contact plate, the bracket having a base, a guide rod located on the upper surface of the base, and casters located on the lower surface of the base, the lower surface of the contact plate having a sleeve that inserts into the guide rod, a spring placed inside the sleeve, the lower end of the spring abutting against the upper end face of the guide rod, and the upper end of the spring abutting against the lower surface of the contact plate;

[0020] The upper surface of the base is connected to an electric telescopic rod, and the output end of the electric telescopic rod is fixedly connected to the lower surface of the contact plate. With this structural design, the guide rod and the sleeve cooperate to guide the base, the spring is used for auxiliary support, the electric telescopic rod is used to adjust the height of the base, and the casters are used to realize transfer.

[0021] The beneficial effects of this invention are as follows: The V-shaped trajectory of the insulating film J and the first rotating roller have a larger wrapping angle, which enables the first rotating roller and the insulating film J to move synchronously, avoiding slippage that could lead to measurement errors. The rotation angle of the first rotating roller is measured by an encoder. After knowing the rotation angle of the first rotating roller, the moving length of the insulating film J can be obtained through the radius of the first rotating roller. When the set moving length of the insulating film J is detected, the output end of the positioning cylinder quickly descends and engages with the contact plate to stop the insulating film J, preventing the operator from continuously pulling it, which could cause the insulating film J to be unwound too long and form redundant accumulation.

[0041] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] like Figure 1-6 As shown, an insulating film positioning precision mechanism of the present invention includes a programmable logic controller, a material roller 1 for winding the insulating film J, a first rotating roller 3 and a second rotating roller 5 for limiting the movement trajectory of the insulating film J, a positioning cylinder 7 for positioning the position of the insulating film J, and an abutment plate 6 that cooperates with the positioning cylinder 7.

[0043] The material roller 1 has rotational freedom for winding and unwinding;

[0044] The rotating end of the first rotating roller 3 is connected to the encoder 4;

[0045] The first rotating roller 3 is located between the material roller 1 and the second rotating roller 5. The axial height of the first rotating roller 3 is lower than the axial height of the first rotating roller 3 and the second rotating roller 5. The first rotating roller 3 shapes the trajectory of the insulating film J flowing through it into a V shape.

[0046] The output end of the positioning cylinder 7 comes into contact with the contact plate 6, clamping and stopping the insulating film J.

[0047] In this embodiment:

[0048] The V-shaped trajectory insulating film J has a larger coverage angle with the first rotating roller 3, which enables the first rotating roller 3 and the insulating film J to move synchronously, avoiding slippage that could lead to measurement errors. The rotation angle of the first rotating roller 3 is measured by the encoder 4. After knowing the rotation angle of the first rotating roller 3, the moving length of the insulating film J can be obtained through the radius of the first rotating roller 3.

[0049] Once the insulation film J has been moved to the set length, the output end of the positioning cylinder 7 quickly moves downward and comes into contact with the contact plate 6 to stop the insulation film J, thus preventing the staff from pulling it continuously and causing the insulation film J to be unwound too long and form redundant accumulation.

[0050] The programmable logic controller is used to control the positioning cylinder 7.

[0051] Preferably, the output end of the positioning cylinder 7 is connected to the first pressure plate 71, and the lower surface of the first pressure plate 71 is provided with several rubber contacts 72. This structural design ensures that the flexibility of the rubber contacts 72 prevents damage to the insulating film J during pressing. In practice, other clamping structures can also be considered depending on the specific circumstances.

[0052] Preferably, the shaft of the material roller 1 is connected to the motor 2. With this structural design, the motor 2 can both wind up the insulating film J and prevent the insulating film J on the material roller 1 from continuously unwinding due to inertia by applying a torque in the opposite direction to the unwinding. In practice, other winding structures can also be considered depending on the specific circumstances.

[0053] Preferably, the device also includes a cutting cylinder 8 for cutting the insulating film J. The output end of the cutting cylinder 8 is connected to a second pressure plate 81, and the lower surface of the second pressure plate 81 is connected to a cutting blade 82. With this structural design, the cutting cylinder 8 causes the cutting blade 82 to move downward, thereby cutting the insulating film J. In practice, other structural shapes for cutting the insulating film J can also be considered depending on the specific circumstances.

[0054] Preferably, the upper surface of the contact plate 6 has a cutting groove 62 adapted to the shape of the cutting blade 82 at the position corresponding to the cutting blade 82. With this structural design, the cutting blade 82 penetrates into the cutting groove 62, causing the insulating film J to sink and deform at the position of the cutting groove 62, resulting in breakage and making the cutting more reliable. In fact, other structural shapes for cutting the insulating film J can also be considered according to specific circumstances.

[0055] Preferably, the cross-sectional shape of the cutting blade 82 is triangular, and the edges of the cutting blade 82 are rounded. This structural design makes it safer to use. In fact, other structural shapes of the cutting blade 82 can also be considered depending on the specific situation.

[0056] Preferably, the upper surface of the contact plate 6 is provided with a hemispherical cylindrical film-taking groove 61. The film-taking groove 61 is located between the pressing point of the positioning cylinder 7 and the cutting point of the cutting cylinder 8. With this structural design, after cutting, the film-taking groove 61 makes it convenient for the operator to re-grip the insulating film J and pull the material roller 1 to unwind. The operator puts his palm into the film-taking groove 61 and moves the insulating film J along the inner wall of the film-taking groove 61, exposing the end of the insulating film J to the outside. The operator pulls the insulating film J by pinching the end of the insulating film J. In fact, other structural shapes for holding the insulating film J can also be considered according to specific circumstances.

[0057] Preferably, the design includes an emergency stop button 10 for controlling the positioning cylinder 7 and the cutoff cylinder 8 to stop in an emergency. This structural design allows operators to stop all components by pressing the emergency stop button 10 in case of an accident, preventing the situation from escalating. However, other emergency stop structures can also be considered depending on the specific circumstances.

[0058] Preferably, a blocking sensor 13 is arranged along the downward spatial path of the cutting-off cylinder 8. When the blocking sensor 13 is triggered, the downward air intake of the cutting-off cylinder 8 is cut off. With this structural design, if a worker's hand crosses the space below the cutting-off cylinder 8 to grasp the insulating film J, the blocking sensor 13 will be triggered, and the cutting-off cylinder 8 will not descend, ensuring the worker's safety. In practice, other structural shapes can also be considered to prevent accidents caused by the downward movement of the cutting-off cylinder 8, depending on the specific circumstances.

[0059] Preferably, the support includes a bracket 11 for supporting the contact plate 6. The bracket 11 has a base 111, a guide rod 112 located on the upper surface of the base 111, and a caster 113 located on the lower surface of the base 111. The lower surface of the contact plate 6 has a sleeve 63 that is inserted into the guide rod 112. A spring 12 is placed inside the sleeve 63. The lower end of the spring 12 abuts against the upper end face of the guide rod 112, and the upper end of the spring 12 abuts against the lower surface of the contact plate 6.

[0060] The upper surface of the base 111 is connected to the electric telescopic rod 14, and the output end of the electric telescopic rod 14 is fixedly connected to the lower surface of the contact plate 6. With this structural design, the guide rod 112 cooperates with the sleeve 63 to guide the base 111, the spring 12 provides auxiliary support, the electric telescopic rod 14 adjusts the height of the base 111, and the casters 113 facilitate movement. In practice, other support and movement structures for the base 111 can also be considered depending on the specific circumstances.
