Description

Technical Field

[0001] The invention relates to the field of automobile parts processing, specifically to the field of automobile sound insulation pad processing, and particularly to a high temperature resistant automobile sound insulation pad processing and cutting device. Background Art

[0002] Car sound insulation pads are one of the car interior decoration parts, which play the role of heat insulation and sound insulation. When producing car sound insulation pads, the sound insulation pad raw materials need to be cut to obtain the sound insulation pad products of the desired shape. In the existing technology, the sound insulation pad raw materials are generally cut by knife cutting.

[0003] In the existing tool cutting technology, in order to avoid damage to the tool and scratches on the work surface caused by contact between the tool and the work surface, a cutting pad is generally laid on the work surface to protect the tool and the work surface. The material of the cutting pad is an anisotropic rubber, which is relatively hard in the vertical direction but relatively soft in the horizontal direction. After cutting, because it is very soft in the horizontal direction, the stress distribution of the cut section does not change much. Under the action of van der Waals force, many molecules on the section establish connections, so the sections are adhered together macroscopically. However, this does not mean that frequent cutting can be performed at the same position of the cutting pad. Frequent cutting will still cause damage to the cutting pad. Therefore, when mass-producing the same product, either the cutting trajectory is changed to avoid frequent cutting at the same position of the cutting pad. This method has high requirements on the control of the production line, or the cutting pad must be replaced in time after being damaged, which is more costly.

[0004] In addition, when cutting, the tool feed will not only cut the product raw materials, but also cut the cutting pad. Therefore, the cutting ability of the tool cannot be fully applied to the product and needs to be improved.

[0005] In addition, the tool is generally a blade, which is limited by the cutting pad and can basically only move along a straight line. It is unable to cut the product raw materials into arc or irregular shapes. The cutting has limitations and needs to be improved.

DETAILED DESCRIPTION

[0041] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0042] In the attached drawings of this scheme, a refers to the sound insulation pad material to be cut.

[0043] Reference Figure 1-Figure 8 A high temperature resistant automobile sound insulation pad processing and cutting device comprises a cutting frame 100, on which a conveyor belt group 101, a clamping member 200 and a cutting member 300 are arranged, wherein the conveyor belt group 101 is used to support the sound insulation pad material to be cut, the clamping member 200 is used to clamp the two ends of the sound insulation pad material to be cut, and make the sound insulation pad material straight without wrinkles, and the cutting member 300 is used to cut the sound insulation pad material. During the cutting process, the cutting member 300 cooperates with the conveyor belt group 101 to play the following roles: 1. The conveyor belt group 101 is equivalent to the cutting pad in the prior art. The conveyor belt group 101 can not only play the role of the cutting pad, but also the conveyor belt group 101 will not be damaged during the cutting process, that is, there is no need to frequently replace the cutting pad; 2. The cutting capacity generated by the cutting action of the cutting member 300 is fully applied to the sound insulation pad material, and the cutting effect and efficiency are better; 3. The cutting action trajectory of the cutting member 300 is not restricted, and it can move in any trajectory.

[0044] Reference Figure 3 The conveying direction of the conveyor belt group 101 is horizontally arranged. The conveyor belt group 101 can be realized by existing conveyor belt technology and will not be described in detail.

[0045] The clamp member 200 includes two clamp assemblies respectively located at two ends of the conveyor belt assembly 101 . The clamp assemblies include a driving roller 202 and a driven roller 205 , and the axis directions of both are parallel to the width direction of the conveyor belt of the conveyor belt assembly 101 .

[0046] A roller bracket 203 is slidably disposed on the cutting frame 100 in the vertical direction. A first spring 204 is disposed between the roller bracket 203 and the cutting frame 100 . The elastic force of the first spring 204 is used to drive the roller bracket 203 to move downward.

[0047] The active roller 202 is installed on the cutting frame 100 , and the highest point of the outer circumferential surface of the active roller 202 is flush with the upper surface of the conveyor belt of the conveyor belt group 101 . The cutting frame 100 is provided with a first motor 201 for driving the active roller 202 to rotate.

[0048] The driven roller 205 is mounted on the roller bracket 203 and is located directly above the driving roller 202 .

[0049] One end of the sound insulation pad material is passed through the area between the active roller 202 and the driven roller 205 of the two clamp assemblies in sequence, and the sound insulation pad material is clamped by the cooperation of the two clamp assemblies. In addition, the sound insulation pad material is supported by the conveyor belt group 101. In addition, when the first motors 201 of the two clamp assemblies operate in different directions, they can apply forces in opposite directions to the two ends of the sound insulation pad material to flatten the sound insulation pad material. When operating in the same direction, they can pull the sound insulation pad material to move. When not operating, the sound insulation pad material is clamped.

[0050] Reference Figure 3-Figure 5 The cutting component 300 includes a column bracket 302 that is slidably connected to the cutting frame 100 along the conveying direction of the conveyor belt group 101, and a first linear module 301 for driving the column bracket 302 to move. The first linear module 301 and the second linear module 303 mentioned later can adopt the existing electric telescopic rod technology or the existing screw linear motion technology, etc., which will not be elaborated.

[0051] The column bracket 302 is provided with an upper cross bracket 304 and a lower cross bracket 305, and the extension direction of both is parallel to the width direction of the conveyor belt of the conveyor belt group 101, wherein the upper cross bracket 304 is located above the conveyor belt group 101, and the upper cross bracket 304 and the column bracket 302 form a sliding connection along the vertical direction, and the column bracket 302 is provided with a second linear module 303 for driving the upper cross bracket 304 to move, and the lower cross bracket 305 is located above and below the conveyor belt of the conveyor belt group 101. In the area between the surfaces, the lower cross bracket 305 is fixedly connected to the column bracket 302. Furthermore, a notch is provided on the upper surface of the conveyor belt, and the length direction of the notch is parallel to the width direction of the conveyor belt. A rectangular convex tube 3051 is provided at the upper end of the lower cross bracket 305. The rectangular convex tube 3051 is fixedly set in the notch. Therefore, when the column bracket 302 moves with the lower cross bracket 305, the lower cross bracket 305 can pull the conveyor belt to move together, that is, the lower cross bracket 305 moves synchronously with the conveyor belt.

[0052] Reference Figure 6-Figure 8 , both the upper horizontal bracket 304 and the lower horizontal bracket 305 are provided with connecting units, and a blade 316 is provided between the two connecting units.

[0053] The connecting unit includes a sliding bracket 309 which is slidably connected to the upper horizontal bracket 304 or the lower horizontal bracket 305. The sliding direction of the sliding bracket 309 is parallel to the width direction of the conveyor belt. A rotating shaft 310 is installed on the sliding bracket 309. The axis of the rotating shaft 310 is arranged vertically. A fixing ring 311 is provided on the outer circular surface of the rotating shaft 310. The outer sleeve of the rotating shaft 310 is provided with two second springs 312 which are respectively located on the upper and lower sides of the fixing ring 311. Therefore, the rotating shaft 310 can move along the axis direction and rotate around the axis.

[0054] In addition, the connection unit further includes a vibrator 313 for driving the rotating shaft 310 to vibrate in the vertical direction. The vibrator 313 of the connection unit on the lower horizontal bracket 305 is not shown in the figure.

[0055] In addition, the connecting unit also includes a third motor 314 for driving the rotating shaft 310 to rotate. Specifically, a power transmission member is arranged between the third motor 314 and the rotating shaft 310. The driven member of the power transmission member is arranged on the rotating shaft 310 through the first connecting member, and when the rotating shaft 310 moves along the axial direction, the driven member continuously outputs power to the rotating shaft 310. Preferably, the first connecting member includes an external spline arranged on the rotating shaft 310 and an internal spline arranged on the driven member.

[0056] A handle 315 is provided at the lower end of the rotating shaft 310 in the connecting unit on the upper horizontal bracket 304 , and the handle 315 is fixed to the blade 316 .

[0057] The upper end of the rotating shaft 310 in the connecting unit on the lower horizontal bracket 305 is provided with a knife groove, and the blade 316 can be inserted into the knife groove, and the notch of the knife groove is flush with the upper surface of the conveyor belt.

[0058] Reference Figure 6 The column bracket 302 is also provided with a driving member for driving the sliding brackets 309 in the two connecting units to move.

[0059] The driving member includes a driving shaft 307 and a second motor 306 which are arranged on the column bracket 302. The axis of the driving shaft 307 is arranged vertically, and the second motor 306 is used to drive the driving shaft 307 to rotate.

[0060] A synchronous belt group 308 is provided on both the upper horizontal bracket 304 and the lower horizontal bracket 305. The synchronous belt of the synchronous belt group 308 is connected to the corresponding sliding bracket 309. The traction direction of the synchronous belt group 308 is parallel to the sliding direction of the sliding bracket 309. Therefore, the operation of the synchronous belt group 308 can pull the sliding bracket 309 to move.

[0061] Since the lower cross bracket 305 is fixedly connected to the column bracket 302 , the driving pulley in the synchronous belt set 308 on the lower cross bracket 305 can be directly set on the driving shaft 307 .

[0062] Since the upper cross bracket 304 is slidably connected to the column bracket 302, the driving pulley in the synchronous belt group 308 on the upper cross bracket 304 is set on the driving shaft 307 through the second connecting member. When the upper cross bracket 304 moves in the vertical direction, the driving shaft 307 continuously outputs power to the driving pulley through the second connecting member. Preferably, the second connecting member includes an external spline arranged on the driving shaft 307 and an internal spline arranged on the driving pulley.

[0063] Therefore, the second motor 306 can drive the sliding bracket 309 to move on the upper cross bracket 304 or the lower cross bracket 305 .

[0064] Working principle of the present invention:

[0065] First, one end of the sound insulation pad material is passed through the area between the active roller 202 and the driven roller 205 of the two clamp assemblies in sequence, and the sound insulation pad material is clamped by the cooperation of the two clamp assemblies;

[0066] Then, the second linear module 303 drives the upper horizontal support 304 to move downward, and the upper horizontal support 304 moves downward with the blade 316, and the lower end of the blade 316 passes through the sound insulation pad material and is inserted into the blade groove;

[0067] Then, the first linear module 301 can drive the column bracket 302 to move along the conveying direction of the conveyor belt group 101, and the column bracket 302 moves with the upper cross bracket 304, the lower cross bracket 305 and the blade 316, and the lower cross bracket 305 moves with the conveyor belt. Therefore, the blade 316 can cut the sound insulation pad material along the conveying direction of the conveyor belt;

[0068] Then, the upper horizontal support 304 is driven upward by the second linear module 303, and the blade 316 is separated from the sound insulation pad material. Then, the blade 316 is driven to rotate ninety degrees by the third motor 314, and then the blade 316 is moved downward and inserted into the blade groove.

[0069] Then, the synchronous belt set 308 is driven to move by the second motor 306, and the synchronous belt set 308 moves with the connection unit and the blade 316, so that the sound insulation pad material can be cut along the width direction of the conveyor belt by the blade 316;

[0070] In addition, through the cooperation of the first linear module 301, the second motor 306 and the third motor 314, the blade of the blade 316 can be moved arbitrarily on the plane coordinate system, so that the sound insulation pad material can be cut by the blade 316 at any cutting trajectory;

[0071] In addition, when cutting, the vibrator 313 is activated to drive the blade 316 to move up and down, which plays a sawing role and has a better cutting effect;

[0072] In addition, the advantage of the connecting unit arranged on the lower horizontal bracket 305 is that, on the one hand, it plays a role of supporting the knife, strengthening the strength of the blade 316 and preventing the knife from breaking easily; on the other hand, the upper end of the rotating shaft 310 supports the cutting position of the sound insulation pad, thereby improving the flatness of the cutting section.

[0073] From the above, we can know that:

[0074] In the present solution, the conveyor belt plays the role of the cutting pad in the prior art, and during the cutting process, due to the setting of the notch, the blade will not cut the conveyor belt, so the conveyor belt will not be damaged, which solves the problem of frequent replacement of the cutting pad mentioned in the background technology. The cutting ability of the blade is fully applied to the sound insulation pad raw material, so the cutting effect and cutting efficiency are better. In addition, the cutting action trajectory of the blade is not restricted, and the blade edge can cut the sound insulation pad raw material with any cutting trajectory, so it can cut out sound insulation pads of any shape, which is more applicable.

[0075] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
