Description

Technical Field

[0001] This utility model relates to the field of profile cutting, specifically to a tailless CNC strip saw that automatically reads the cutting dimensions. Background Technology

[0002] Like window and door frame profiles, aluminum door and window trim strips require pre-cutting to specific dimensions based on the original profiles. However, unlike window and door frames which can be pre-programmed for optimized cutting and automated production, trim strips, which must match the frame and door frame dimensions, cannot be pre-cut automatically. They must be cut to specific dimensions after frame and door assembly, based on actual measurements. This presents two problems: first, the cutting dimensions cannot be systematically optimized, resulting in significant waste of excess material; second, before cutting, the corresponding window frame side lengths must be manually measured, marked, and then cut, leading to low efficiency and a high error rate. To address these issues, a CNC trim strip saw with no tail material and automatic cutting dimension reading has been invented. This CNC trim strip saw connects to a Bluetooth dimension measuring instrument for window and door frames, automatically reading the corresponding side lengths for real-time data transmission and automatic optimized material arrangement. The equipment employs a high-precision servo control system to ensure cutting accuracy. Meanwhile, the machine is equipped with automatic feeding and automatic cutting functions, which effectively improves production efficiency and reduces reliance on manual labor. The optimized structure of the strip saw belt can consume as much scrap material as possible, thus solving the problems of low efficiency, large error and material waste in traditional manual measurement.

[0003] Therefore, in order to solve the above-mentioned problems, a tailless CNC strip saw that automatically reads the cutting dimensions is proposed. Utility Model Content

[0004] This invention addresses the aforementioned problems by designing a tailless CNC strip saw that automatically reads the cutting dimensions. This device can synchronously identify and read dimensional data from a Bluetooth measuring instrument and automatically cut the material to the correct length, reducing the inefficiency and poor accuracy caused by manual measurement. Through tail material optimization, the feeding robot and the discharging robot interact with the tail material profile, maximizing the use of the tail material and reducing waste.

[0005] To achieve the above objectives, this utility model provides a tailless CNC strip saw that automatically reads the blanking dimensions, comprising: a machine frame, a feeding robot assembly, a sawing machine assembly, and a discharge assembly. The front and rear ends of the machine frame are respectively provided with a loading area and a unloading area. The robot assembly is slidably connected to the loading area of ​​the machine frame. The sawing machine assembly is mounted on the machine frame and located between the loading area and the unloading area. The discharge assembly is mounted on the side of the sawing machine assembly closer to the unloading area. A controller that receives signals from a Bluetooth measuring instrument is mounted on the machine frame, and the controller is connected to the signals of each component.

[0006] In the above manner, the Bluetooth measuring instrument measures the internal dimensions of the window frame to be installed, transmits the measured data to the controller, and the controller controls the feeding robot assembly to push the profile to the appropriate size. The sawing assembly cuts the profile, and the discharge assembly transports the cut profile to the unloading area. When the last piece of material is cut, the discharge assembly can clamp the last piece of material and transport it in the opposite direction to continue cutting.

[0007] Furthermore, the feeding robot assembly includes: a feeding servo drive assembly, a drive plate, a slide, a slide plate, a robot arm assembly, and a lead screw assembly. The drive plate is slidably connected to the machine tool frame and fixedly connected to the feeding servo drive assembly. A guide rail is mounted on the back of the machine tool frame, and the feeding servo drive assembly is connected to the guide rail.

The drive unit is installed on the lower part of the sawing table. A slot is opened on the sawing table. The drive unit is connected to the saw blade, and the saw blade is placed in the slot. The positioning and clamping device is installed on the sawing table. The discharge assembly is installed on the sawing table.

[0009] Furthermore, the discharge assembly includes: a discharge robot frame, a discharge robot slide, a discharge servo drive assembly, a clamping cylinder, a rear upright plate, and a front upright plate. The discharge robot frame is fixedly connected to the sawing table. The discharge robot slide is slidably connected to the discharge robot frame through the discharge servo drive assembly. The clamping cylinder is fixedly connected to the discharge robot slide. The front upright plate is connected to the movable end of the clamping cylinder. The rear upright plate is fixedly connected to the side of the discharge robot slide.

[0010] Furthermore, the driving device includes: a feed cylinder, a balance cylinder, a sawing slide, and an electric spindle.

[0011] Furthermore, the positioning and clamping device includes: a clamping cylinder, a clamping cylinder seat, a rear positioning plate, a rear positioning slide, a clearance structure, and a dust cover. The clamping cylinder is mounted on the sawing table via the clamping cylinder seat. The dust cover is mounted on the slot. The rear positioning plate is fixedly connected to the rear positioning slide. The positioning slide is slidably connected to the side of the dust cover via the clearance structure.

[0012] Furthermore, the avoidance structure includes a linear guide rail and an avoidance cylinder.

The mounting block is fixedly connected to the lower part of both the slide block and the slide plate. The eccentric shaft is connected to the mounting block via the handle, and the eccentric shaft is in contact with the slide rail surface of the lead screw assembly.

[0015] By rotating the handle as described above, the handle drives the eccentric shaft to rotate. The eccentric shaft abuts against the surface of the slide rail, forming a fixing effect. The fixing of the mounting block also fixes the slide seat and slide plate connected to it. Therefore, the various degrees of freedom of the feeding robot assembly are fixed, which can maintain the stability of the structure when transporting profiles.
