The first lower clamping block 3212 is embedded in the horizontal support platform 12, with its top surface flush with the top surface of the horizontal support platform 12, capable of contacting the lower surface of the dashboard diaphragm. The first upper clamping block 3211 is rotatably connected to the first lower clamping block 3212. The first clamping actuator 3213 can drive the first upper clamping block 3211 to rotate vertically, causing the first upper clamping block 3211 to press the dashboard diaphragm against the first lower clamping block 3212.

[0050] The second clamping assembly 322 includes a second upper clamping block 3221 and a second clamping drive 3223. The second clamping drive 3223 can drive the second upper clamping block 3221 to rotate horizontally to above the diaphragm for the automobile dashboard, and then descend vertically to press the diaphragm for the automobile dashboard tightly against the horizontal support platform 12.

[0051] In this embodiment, there are three first clamping assemblies 321, arranged side by side on one side of the horizontal support platform 12; there are two second clamping assemblies 322, one on each side of the three first clamping assemblies 321.

[0054] like Figure 1 、 9 As shown, the first horizontal movement unit 41 includes a first horizontal drive motor 411, at least one first horizontal guide rail 412, and at least one first slider 413 adapted to the first horizontal guide rail 412. The first horizontal guide rail 412 is disposed on the bracket 11 along a first horizontal direction, and the first slider 413 is movably disposed on the first horizontal guide rail 412. The first horizontal drive motor 411 is connected to the first slider 413 and is capable of driving the first slider 413 to slide along the first horizontal guide rail 412.

[0055] In this embodiment, in order to improve stability during movement, the number of the first horizontal guide rails 412 and the first slider 413 are both set to two, the two first horizontal guide rails 412 are parallel to each other, and the two first sliders 413 are respectively set on the two first horizontal guide rails 412.

[0056] The first horizontal moving unit 41 also includes a transmission gear and a rack 414 that cooperates with the transmission gear. The rack 414 is disposed on one side of one of the first horizontal guide rails 412 and is parallel to the first horizontal guide rail 412. The first horizontal drive motor 411 is mounted on the first slider 413 corresponding to the first horizontal guide rail 412. The gear is disposed at the output end of the first horizontal drive motor 411 and meshes with the rack 414. During operation, the gear rotates under the drive of the first horizontal drive motor 411, meshing with the rack 414 while moving along the extension direction of the rack, thereby driving the first slider 413 to slide along the corresponding first horizontal guide rail 412.

[0057] The second horizontal movement unit 42 includes a second horizontal drive motor 421, a second horizontal guide rail 422, and a second slider 423 adapted for the second horizontal guide rail 422. The two ends of the second horizontal guide rail 422 are connected to the two first sliders 413, respectively, so that the two first sliders 413 can move synchronously under the drive of the first horizontal drive motor 411. The second horizontal drive motor 421 can drive the second slider 423 to move along the second horizontal guide rail 422.

[0058] The lifting unit 43 includes a lifting drive cylinder connected to the cutting portion 50. The lifting drive cylinder 431 is disposed on the second slider 423.

The upper portion of the connecting plate 53 is connected to the output end of the lift drive cylinder 431, and the blade 51 is disposed at the lower portion of the connecting plate 53. The blade guard 52 is a baffle that semi-encloses the blade 51 and is mounted on the second slider 423. It can protect the blade 51 and prevent it from accidentally injuring personnel or other mechanical structures. The blade guard 52 is parallel to the movement direction of the blade 51. The blade 51 can move vertically under the drive of the lift drive cylinder 431, thereby extending or retracting into the blade guard 52.

[0061] The upper portion of the horizontal support platform 12 is also provided with a plurality of cutting limit grooves 121 extending along a second horizontal direction. The lengths and positions of the plurality of cutting limit grooves 121 correspond to the cutting positions of four different types of diaphragms. The width of the cutting limit grooves 121 is adapted to the thickness of the blade 51, thereby limiting the cutting position of the blade 51. During cutting, the end of the blade 51 engages with the corresponding cutting limit groove 121 and moves along the cutting limit groove 121, making the cutting position more precise and improving the precision and quality of the finished product.

[0075] Step S3-1: The controller 60 controls the first horizontal moving unit 41 to drive the cutting portion 50 to move along the first horizontal direction and align with the position to be cut;

[0076] In step S3-2, the controller 60 controls the lifting unit 43 to drive the blade 51 to extend from the blade protection cover 52 and descend to a height corresponding to the diaphragm for the car dashboard;

2. The film cutting device for automobile instrument panel according to claim 1, characterized in that: in, The clamping unit further comprises a plurality of second clamping assemblies, The second clamping assembly includes a second upper clamping block and a second clamping drive member, The second clamping drive member is used to drive the second upper clamping block to rotate horizontally or to lift vertically, so that the second upper clamping block presses the automobile instrument panel diaphragm tightly against the support portion.

3. The film cutting device for automobile instrument panel according to claim 1, characterized in that: in, The moving part includes a first horizontal moving unit, a second horizontal moving unit and a lifting unit. The first horizontal moving unit and the second horizontal moving unit are used to drive the cutting part to move along the first horizontal direction and the second horizontal direction respectively. The lifting unit is used to drive the cutting part to move up and down. During cutting, the control unit first controls the first horizontal moving unit to drive the cutting unit to move along the first horizontal direction and align with the position to be cut, then controls the lifting unit to drive the cutting unit down to a height corresponding to the film for the car dashboard, and finally controls the second horizontal moving unit to drive the cutting unit to move along the second horizontal direction to cut the film for the car dashboard.

4. The film cutting device for automobile instrument panel according to claim 3, characterized in that: in, The first horizontal moving unit includes a first horizontal driving motor, at least one first horizontal guide rail, and at least one first sliding block adapted to the first horizontal guide rail. The first horizontal driving motor is used to drive the first slider to move along the first horizontal guide rail. The second horizontal moving unit includes a second horizontal driving motor, a second horizontal guide rail, and a second sliding block adapted to the second horizontal guide rail. The second horizontal guide rail is arranged on the first sliding block, The second horizontal driving motor is used to drive the second slider to move along the second horizontal guide rail. The lifting unit includes a lifting drive cylinder connected to the cutting part, The lifting drive cylinder is arranged on the second sliding block.

5. The film cutting device for automobile instrument panel according to claim 4, characterized in that: in, The first horizontal moving unit further includes a transmission gear and a rack matched with the transmission gear.
