Technical Field

[0001] The utility model relates to the technical field of polycarbonate plate processing equipment, in particular to a fixing component for trimming a polycarbonate plate. Background Art

[0002] Polycarbonate sheets are widely used in the fields of construction, electronics, medical treatment, optics and packaging due to their excellent light transmittance, impact resistance, heat insulation and flame resistance. After being formed, polycarbonate sheets need to be fixed and trimmed so that they can be processed into specified sizes, improve their installation accuracy and, according to needs, be trimmed to make their appearance more beautiful. Some existing polycarbonate sheet trimming fixing components are fixed by suction cups arranged in a matrix. The polycarbonate sheet is fixed by adsorption of multiple suction cups. Since the trimming size of polycarbonate sheets is not fixed, the arrayed suction cups will hinder the cutting of some sizes, reducing the applicable range of trimming size.

[0003] Existing patent application No. 202323527474.5 discloses a polycarbonate windshield trimming device. This device utilizes a mounting bracket and a rubber support frame to facilitate positional fixation of a polycarbonate sheet placed on the surface of a fixing assembly 4 by utilizing the friction and adsorption properties of the rubber. However, this prior art device still suffers from the aforementioned technical problems when fixing polycarbonate sheets. Utility Model Content

An adsorption cavity is provided on the top of the support cylinder. The support cylinder is used to support and adsorb and fix the polycarbonate plate.

[0015] Furthermore, the pressing plate comprises:

[0016] A supporting outer sleeve is vertically fixed on the upper bracket.

[0017] A second telescopic cylinder is fixed in the supporting outer sleeve.

[0018] The downward pressing suction cup provided at the output end of the second telescopic cylinder is rotated.

[0035] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0036] like Figures 1 to 3As shown, a fixing assembly for trimming a polycarbonate sheet comprises a trimming base 1 and a plate placement slot 2 provided on the top of the trimming base 1; a first screw is rotatably provided on the trimming base 1; a sliding frame is provided on a threaded sleeve of the screw, and a servo motor is used to drive the screw to rotate; a second screw is provided in the sliding frame, and a driving motor is used to drive the second screw to rotate; a movable seat is provided on a threaded sleeve of the second screw; a laser cutting machine for trimming a polycarbonate sheet is provided at the bottom of the movable seat; the second screw is perpendicular to the first screw in the horizontal direction, the axial direction of the first screw is the X coordinate direction, and the axial direction of the second screw is the Y direction, so as to facilitate adjustment of the position of the laser cutting machine in the X and Y directions to achieve precise trimming operation; the fixing assembly for trimming a polycarbonate sheet further comprises:

[0037] A bottom support portion 4 is provided in the plate placement groove 2 for supporting and fixing the polycarbonate plate.

[0038] The upper bracket 5 is fixed on the top of the trimming base 1. The upper bracket 5 includes a column fixed at the top boundary of the trimming base 1 and a beam fixed laterally to the top of the column. The design is such that one end of the beam is suspended above the center of the plate placement groove 2.

[0039] A pressing plate 6 is provided on the upper bracket 5 for pressing the polycarbonate sheet material onto the bottom supporting portion 4 .

[0040] The bottom support portion 4 includes:

[0041] A supporting outer frame 41 is vertically fixed in the plate placement groove 2 .

[0042] The inner support frame 43 is slidably mounted inside the outer support frame 41 .

[0043] A first telescopic cylinder 42 is vertically fixed in the support outer frame 41 . The first telescopic cylinder 42 is used to push the support inner frame 43 to slide up and down in the support outer frame 41 .

[0044] The support cylinder 44 is rotatably arranged on the top of the support inner frame 43. The outside of the support cylinder 44 is a toothed surface. The support cylinder 44 is sleeved on the outside of the support outer frame 41. The top of the support cylinder 44 is provided with an adsorption chamber 45. The support cylinder 44 is used to support and adsorb and fix the polycarbonate plate.

[0045] In this embodiment, the pressing plate 6 includes:

[0046] A supporting outer sleeve 61 is vertically fixed on the upper bracket 5 .

[0047] The second telescopic cylinder 62 is fixed in the supporting outer sleeve 61 .

[0048] The downward pressing suction cup 63 provided at the output end of the second telescopic cylinder 62 is rotated. The second telescopic cylinder 62 is used to push down the downward pressing suction cup 63 so that the downward pressing suction cup 63 presses the polycarbonate sheet tightly against the top of the supporting cylinder 44 .

[0049] The second telescopic cylinder 62 is located between the upper bracket 5 and the downward pressing suction cup 63 , and the output end of the second telescopic cylinder 62 is vertically downward.

[0050] This design makes it easy to control the second telescopic cylinder 62 to push the downward suction cup 63 downward, so that the downward suction cup 63 presses the polycarbonate sheet against the top of the supporting cylinder 44, thereby achieving efficient fixing operation of the polycarbonate sheet and reducing the difficulty of fixing the polycarbonate sheet.

[0051] In this embodiment, the bottom supporting portion 4 further includes:

[0052] The limiting block 47 is fixed to the outside of the supporting inner frame 43 , and the limiting block 47 is slidably sleeved with the guide vertical groove 46 provided on the supporting outer frame 41 .

[0053] A driving member 48 is provided in the plate placement groove 2 for driving the supporting cylinder 44 to rotate.

[0054] With such a design, after the polycarbonate sheet is fixed, the first telescopic cylinder 42 and the second telescopic cylinder 62 can be controlled to operate synchronously, so that the output end of the first telescopic cylinder 42 extends and the output end of the second telescopic cylinder 62 retracts at the same speed. While keeping the polycarbonate sheet fixed, the polycarbonate sheet is lifted up to a certain height, and then the driving member 48 is started to drive the supporting cylinder 44 to rotate, thereby horizontally adjusting the direction of the boundary to be trimmed of the polycarbonate sheet. Then, the output end of the first telescopic cylinder 42 is controlled to retract and the output end of the second telescopic cylinder 62 is controlled to extend synchronously, thereby realizing the vertical resetting of the polycarbonate sheet so that the boundary to be trimmed on it faces the laser cutting machine, which facilitates the trimming operation on all boundaries of the polycarbonate sheet.

[0055] In this embodiment, the support inner frame 43 is sleeved on the outside of the first telescopic cylinder 42, and the top of the inner wall of the support inner frame 43 is fixed on the output end of the first telescopic cylinder 42. Such a design can limit the lifting and lowering of the guide support cylinder 44 and improve its lifting stability.

[0056] In this embodiment, the fixing assembly for trimming the polycarbonate plate further includes a plate support 3 disposed in the plate placement groove 2 , and the plate support 3 is used to stably support the polycarbonate plate.

[0057] The plate support 3 includes:

[0058] Several supporting vertical plates 31 fixed in the plate slot 2:

[0059] The connecting plate 32 is fixed between two adjacent supporting vertical plates 31. The connecting plate 32 and the supporting vertical plates 31 together form a three-dimensional plate supporting area. This design is to facilitate the flat support of the upper boundary of the polycarbonate plate, to prevent the parts other than the fixed parts of the polycarbonate plate from bending slightly downward under the action of gravity due to the large suspended area, thereby affecting the accuracy of the trimming. It can also make the edge of the polycarbonate plate to be trimmed suspended between the supporting cylinder 44 and the laser cutting machine, which can not only avoid the obstruction of the trimming operation by parts, but also expand the applicable range of the trimming size.

[0060] The driving member 48 includes an intermittent motor fixed in the plate slot 2 and a double-headed gear rod rotatably arranged on the connecting plate 32. A flat gear is provided at the output end of the intermittent motor. The tooth surface of the flat gear is meshed with the tooth surface of one end of the double-headed gear rod, and the tooth surface of the remaining end of the double-headed gear rod is meshed with the tooth surface of the supporting cylinder 44, so that the intermittent motor drives the supporting cylinder 44 to rotate, so as to adjust the boundary to be trimmed on the polycarbonate sheet toward the laser cutting machine, thereby facilitating the subsequent trimming operation on any boundary of the polycarbonate sheet.

[0061] Working principle: Place the polycarbonate sheet on the top of the support cylinder 44, and make the edge of the polycarbonate sheet to be trimmed hang on the outside of the support cylinder 44 away from the side of the sheet support 3, and make the remaining part of the polycarbonate sheet flat on the top of the sheet support 3, then control the output end of the second telescopic cylinder 62 to extend, so that it pushes the downward suction cup 63 downward and squeezes it on the top of the polycarbonate sheet, so that the polycarbonate sheet is pressed between the downward suction cup 63 and the support cylinder 44, and the fixing operation of the polycarbonate sheet is completed. When the edge of the polycarbonate sheet to be trimmed needs to be replaced, it can be replaced by controlling the output end of the first telescopic cylinder 42. The extension and contraction of the output end of the second telescopic cylinder 62 are synchronized to lift the polycarbonate sheet to a certain height, so that the polycarbonate sheet is separated from the top of the sheet support 3, and then the driving member 48 is controlled to drive the support sleeve 44 to rotate. While keeping the polycarbonate sheet pressed and fixed, the direction of the edge to be cut of the polycarbonate sheet is adjusted horizontally and circumferentially, so that one of the edges to be cut faces the laser cutting machine, and the edge to be cut is located between the support cylinder 44 and the laser cutting machine, so that the debris generated by the cutting is concentrated in a fixed area in the plate placing groove 2, which is convenient for subsequent centralized processing of the debris and improves the efficiency of subsequent cleaning work.
