Description

Technical Field

[0001] This utility model relates to the field of automotive seat heating, and in particular to an automotive heating pad cutting mechanism. Background Technology

[0002] Vehicle seat heating typically utilizes electric heating wires within the seat to heat the interior, transferring heat to the occupant and alleviating discomfort caused by cold seats after prolonged parking in winter. In the manufacturing process of heated seats, copper wire can be used as the heating element. The production of seat heating components often requires cutting a large piece of fabric with copper wires sewn on it into smaller, more easily processed pieces. These smaller pieces are then sewn together in later processes, and the copper wires are welded together. Therefore, equipment capable of cutting both copper wires and fabric is needed to pre-cut the fabric containing the copper wires for easier processing.

[0003] However, when cutting fabric on the production line, the cutting direction often needs to be changed as needed, and the cutting trajectory needs to be long. Existing cutting mechanisms often produce vibrations due to the unstable direction of the blade during cutting, resulting in poor cutting quality. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] like Figures 1 to 3 As shown, a car heating pad cutting mechanism in this embodiment includes: a planar module 1, a rotating device 2, a connector 3, a telescopic cylinder 4, a cutting assembly 5, a locking assembly 6, a camera positioning assembly 7, and a pneumatic assembly 8.

[0034] The planar module 1 includes two mutually perpendicular X-axis 101 and Y-axis 102 mounted on a first sliding plate 103. A second sliding plate 104 for mounting related components is also mounted on the X-axis 101. In this embodiment, the Y-axis 102 is bolted to an external bracket (not shown) to ensure the stability of the motion mechanism. Further, an X-axis drive motor 105 is mounted at one end of the X-axis 101, and a Y-axis drive motor 106 is mounted at one end of the Y-axis 102. When the Y-axis drive motor 106 drives the first sliding plate 103, the X-axis 101 and the components mounted on the second sliding plate 104 are driven to move along the Y-axis direction; similarly, when the second sliding plate 104 on the X-axis 101 is driven by the X-axis drive motor 105, the components mounted on the second sliding plate 104 are driven to move along the X-axis direction. The upper and lower end faces of the first sliding plate 103 and the second sliding plate 104 have several threaded holes for fixing other components.

[0035] like Figures 4 to 6As shown, the rotating device 2 is fixed to the bottom surface of the second slide plate 104 of the planar module 1. The rotating part 300 of the connector 3 is fixedly connected to the rotating device 3. The movable end cap of the telescopic cylinder 4 is fixed downward on the connecting part 320 of the connector 3. The cutting assembly 5 is fixed to the telescopic cylinder 4. In this embodiment, the rotating device 2 is a rotary cylinder, and the cylinder body of the rotary cylinder is fixed to the bottom surface of the second slide plate 104 by screws. Optionally, the rotating device 2 can also be an electric rotating device with a reduction speed system.

[0036] Further reference Figure 4 The connector 3 includes a rotating part 300 and a locking groove 310 disposed on the rotating part 300. The rotating part 300 has several first screw holes 301, through which screws and other fasteners are used to fix the connector 3 to the rotating device 2. The locking groove 310 includes a first groove 311 and a second groove 312, with a first locking groove 313 and a second locking groove 314 respectively provided for locking direction. Furthermore, the connector 3 also includes a connecting part 320, with a second screw hole 321 at the end of the connecting part 320 away from the rotating part 300, to which the telescopic cylinder 4 is fixed by screws. Optionally, the rotating part 300 and the connecting part 320 of the connector 3 can also be two independent structures, which can be connected by screws.

[0037] Further reference Figure 5 and Figure 6 The cutting component 5 is fixed to the movable end cap of the telescopic cylinder 4 by screws, and the locking component 6 is fixed to the bottom surface of the second slide plate 104 in the planar module 1. The locking component 6 includes a driving device 61 and a locking pin 62. In this embodiment, the driving device 61 is a cylinder. Optionally, the driving device 61 can also be an electric driving device with a reduction system. The locking pin 62 is perpendicularly arranged to the rotating part 300 of the connecting member 3, and one end is fixedly connected to the driving device 61 by threads or other means. When the rotating device 2 drives the connecting member 3 to a designated position, the other end of the locking pin 62 engages with the locking groove 310 under the drive of the driving device 61.

[0038] like Figure 5As shown, the cutting assembly 5 includes a cutting blade 51 and a blade fixing assembly 52. ​​The blade fixing assembly 52 is fixedly connected to the telescopic cylinder 4, and the cutting blade 51 is fixed on the blade fixing assembly 52. ​​Further, the blade fixing assembly 52 includes a blade fastener 520, a blade shaft 521, bearings 522, and a first fixing member 523. One end of the blade shaft 521 is threaded, and the cutting blade 51 is sleeved on one end of the blade shaft 521 and locked by the blade fastener 520. In this embodiment, the blade fastener 520 is a pair of flange nuts that abut against the two ends of the cutting blade 51. The other end of the blade shaft 521 passes through a pair of bearings 522. The first fixing member 523 is a hollow cubic bracket, which is fixedly connected to the movable end cap of the telescopic cylinder 4 by screws. Each of the two opposite sides of the first fixing member 523 has a bearing hole 524, and the two bearings 522 pass through the bearing hole 524, fixing the blade shaft 521 at two points to ensure the stability of the blade shaft 521 during rotation.

[0039] like Figure 6 As shown, the automotive heating pad cutting mechanism also includes a camera positioning assembly 7. The camera positioning assembly 7 includes a camera 71, a light source 72, and a second fixing member 73. In this embodiment, the second fixing member 73 is a specially structured bracket, including a connecting plate 731 with connecting holes and a fixing plate 732. The camera 71 is fixed to the connecting plate 731 by bolts and nuts. The fixing plate 732 is a steel plate with multiple bends. One end of the fixing plate 732 is fixed to the connecting plate 731 by bolts and nuts, and the other end is fixed to the bottom surface of the second sliding plate 104 in the planar module 1 by screws. A threaded post is welded to the middle of the connecting plate 731, and the light source 72 is connected to the threaded post by threads. In this embodiment, a nut is provided on both the upper and lower sides of the connection between the light source 72 and the threaded post for fastening.

[0040] like Figure 7 As shown, the automotive heating pad cutting mechanism also includes a pneumatic assembly 8. The pneumatic assembly 8 includes a manifold 81 and a solenoid valve assembly 82. The solenoid valve assembly 82 is fixedly mounted on the manifold 81 using hollow bolts with air holes and communicates with the air passage inside the manifold 81. The manifold 81 is fixedly mounted on the upper end face of the first sliding plate 103 on the planar module 1 using screws. The solenoid valve assembly 82 includes a first solenoid valve 821 controlling the rotation device 2, a second solenoid valve 822 controlling the drive device 61, and a third solenoid valve 823 and a fourth solenoid valve 824 controlling the telescopic cylinder 4. The fourth solenoid valve 824 controls the downward pressure of the telescopic cylinder 4 to prevent excessive downward pressure on the cutting blade 51, which could damage the blade's lifespan. All the above solenoid valves are connected to their respective cylinders via air pipes (not shown in the figure). Furthermore, the manifold 81 is provided with an air inlet. High-pressure gas supplied from a single external air source enters the manifold 81 through the air inlet, and after being diverted through the internal air passage of the manifold 81, it is uniformly distributed to the aforementioned solenoid valve.

[0041] like Figure 8 As shown, the automotive heating pad cutting mechanism also includes a host computer 91 and a controller 90 located in an electrical control box (not shown in the figure). The controller 90 is electrically connected to the host computer 91, the light source 72, the solenoid valve group 82, and the planar module 1 via cables. The host computer 91 is also electrically connected to the camera 71 and the controller. In this embodiment of the automotive heating pad cutting mechanism, the controller can be a PLC. Further, the host computer 91 receives and processes the image signals uploaded by the camera 71, and then transmits the processed positioning information to the controller 90 for calculating the distance that the planar module 1 needs to move.

[0042] When this automotive heating pad cutting mechanism is in operation, the fabric with copper wires on the production line workbench moves to the shooting position under the action of the workbench, triggering the controller 90 to start working. The controller 90 controls the light source 72 to emit light via a signal, and simultaneously controls the camera 71 to take a picture. The fabric to be cut has positioning points printed on it for positioning. After processing the image signal transmitted from the host computer 91 and calculating the displacement distance, the controller 90 controls the motor on the planar module 1 via a signal, so that the planar module 1 drives the rotating device 2, the connecting piece 3, the telescopic cylinder 4, the cutting component 5, and the locking component 6 to move from the standby origin to the target position.

[0043] When the fabric needs to be cut along the X-axis 101, the controller sends a signal to the first solenoid valve 821, causing the rotating device 2 to rotate at a set angle, thus rotating the cutting assembly 5 to the same direction as the X-axis 101. Then, the controller sends a signal to the second solenoid valve 822, causing the locking pin 62 of the locking assembly 6 to extend and insert into the first locking groove 313 on the connector 3 to lock the cutting direction, ensuring the cutting blade 51 remains directionally stable during cutting. Next, the controller sends signals to the third solenoid valve 823 and the fourth solenoid valve 824, causing the end cap of the telescopic cylinder 4 to extend, thus pressing the cutting blade 51 onto the fabric. Finally, the controller controls the X-axis drive motor 105 to drive the second slide plate 104, causing the cutting assembly 5 to move along the X-axis 101. The blade shaft 521 rotates due to the pushing force of the second slide plate 104 and the friction between the fabric and the surface of the cutting blade 51, causing the cutting blade 51 to roll along with it. In this embodiment, the cutting blade 51 is made of high-speed steel with high hardness, high wear resistance, and high heat resistance, thus enabling it to cut the fabric along with the copper wires within it at the cutting point. Furthermore, the worktable is made of stainless steel sheet metal with a rubber or plastic coating as a buffer layer, ensuring that the cutting blade 51 can smoothly cut the fabric without causing wrinkles, while also extending the lifespan of the cutting blade 51 itself. After cutting, the controller controls the third solenoid valve 823 and the fourth solenoid valve 824 to retract the end cap of the telescopic cylinder 4, causing the cutting blade 51 to leave the fabric surface.

[0044] When the fabric needs to be cut along the Y-axis 102, after repeating the above-described image positioning process, the controller controls the planar module 1 to move the cutting component 5 to the designated cutting point. Then, the controller sends a signal to the second solenoid valve 822, causing the locking pin 62 of the locking component 6 to retract, releasing the directional lock of the cutting component 5. Subsequently, the controller controls the rotating device 2 to rotate the cutting component 5 to the Y-axis 102 direction, and then controls the locking pin 62 to extend in the locking direction again. Since the connecting piece 3 has already rotated a certain angle under the drive of the rotating device 2, the part on the connecting piece 3 corresponding to the locking pin 62 has switched from the first locking groove 313 to the second locking groove 314. Then, the above process is repeated to control the telescopic cylinder 4 to extend, causing the cutting blade 51 to press against the fabric. Finally, the controller controls the Y-axis drive motor 106 to drive the first slide plate 103, causing the cutting component 5 to move along the Y-axis 102 direction, allowing the lower cutting blade 51 to smoothly cut the fabric.

[0045] After the cutting is completed, the controller controls the end cap of the telescopic cylinder 4 to retract, and finally controls the planar module 1 to drive the cutting component 5 back to the original position to wait for the next cutting command.
