Description

Technical Field

[0001] This utility model relates to the field of glass engraving machine positioning technology, and more specifically, to an adjustable engraving machine positioning device. Background Technology

[0002] Glass engraving machines are a type of CNC machine tool, also known as glass carving machines, glass drilling machines, glass edging machines, irregular glass cutting machines, glass grooving machines, and precision glass forming machines, etc. They are mainly used for the fine processing and irregular cutting of various ultra-thin glasses.

[0003] Currently, before using a CNC engraving machine to engrave glass, the glass needs to be manually placed stably onto several pre-set vacuum adsorption components (the vacuum adsorption components will not come into contact with the engraving tools). The glass's placement is then manually adjusted. Once the glass's placement is corrected, the vacuum adsorption components are activated, which then firmly adsorb the glass onto the vacuum adsorption components for subsequent engraving operations. However, the manual adjustment of the glass's position is prone to errors that are not easily detected, so the glass positioning process before engraving needs to be optimized. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose an adjustable positioning device for a precision engraving machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An adjustable positioning device for a CNC engraving machine includes a processing table and several vacuum adsorption components, as well as positive and negative lead screws, connecting rods, a rectangular frame, and elongated holes.

[0007] The machining table has an installation cavity inside, and the installation cavity is equipped with positive and negative lead screws;

[0008] The two connecting rods are respectively fixedly connected to the two horizontal moving blocks of the positive and negative lead screws;

[0009] A rectangular frame, open on one side and continuous on both the top and bottom, is connected to a connecting rod;

[0010] Elongated holes are symmetrically opened on the machining table, and connecting rods are fitted inside the elongated holes.

[0011] Furthermore, the bottom of the processing table is provided with several drainage holes, and a collection box located below the drainage holes and open at the top is provided on the processing table.

[0012] In the above solution, some of the cooling water sprayed during the glass engraving process will flow down from the elongated hole and then flow through the drain hole at the bottom of the processing table into the collection box for storage, thereby avoiding the problem of water accumulation inside the processing table.

[0013] Furthermore, a rubber layer is fixed on the inner wall of the rectangular frame.

[0014] In the process of placing the glass into the placement area formed by the docking of the two rectangular frames, the glass surface will come into contact with the rubber layer and thus will not be worn.

[0015] Furthermore, a distance sensor is embedded in the end face of the open side of one of the rectangular frames.

[0016] The above solution uses a distance sensor to detect the distance between two rectangular frames in real time. When the distance between the two frames approaches zero, a signal is sent to the controller. The controller then stops the lead screws to prevent the two frames from colliding and being damaged. When the distance between the two frames is about to reach the preset upper limit, a signal is sent to the controller again. The controller then stops the lead screws to accurately limit the position of the frames during the engraving process, thus making the movement position control of the frames more accurate.

[0017] Furthermore, a suction pump is fixed on the processing table, located on one side of the collection box and connected to the inside of the collection box.

[0018] The above solution allows the wastewater to be transferred to other areas for discharge or purification treatment immediately after the cooling water falls into the collection tank, without the need for manual transfer.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Compared to existing technologies, this device uses a vacuum adsorption component to adsorb the glass to be engraved. Before adsorbing the glass, a rectangular frame and positive and negative lead screws can be used to accurately adjust and position the glass placement area. After placement, there is no need for repeated correction and no error, resulting in better subsequent engraving effects. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0027] like Figures 1 to 3 As shown, an adjustable positioning device for a CNC engraving machine includes a processing table 1 and several vacuum adsorption components 2, as well as positive and negative lead screws 3, connecting rods 4, a rectangular frame 5, and elongated holes 6.

[0028] The processing table 1 has an installation cavity inside, and the positive and negative lead screws 3 are installed in the installation cavity;

[0029] The two connecting rods 4 are respectively fixedly connected to the two horizontal moving blocks of the positive and negative lead screws 3;

[0030] A rectangular frame 5, open on one side and continuous on both the top and bottom, is connected to a connecting rod 4;

[0031] Elongated holes 6 are symmetrically opened on the processing table 1, and connecting rods 4 are fitted inside the elongated holes 6.

[0032] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 3 As shown, the bottom of the processing table 1 is provided with several drainage holes 7, and a collection box 8 is provided on the processing table 1 below the drainage holes 7 and open at the top.

[0033] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, a rubber layer 9 is fixed on the inner wall of the rectangular frame 5.

[0034] It should be noted that the positive and negative lead screws 3 are electrically connected to the controller, which is not labeled in the figure.

[0035] The working process of this utility model:

[0036] First, all the glass pieces to be engraved are of the same size and specifications. Before placing the glass to be engraved, the controller moves the positive and negative lead screws 3, which in turn drives the two rectangular frames 5 to move inward synchronously. When the rectangular frames 5 have moved a preset distance, the positive and negative lead screws 3 stop moving. At this time, the two rectangular frames 5 are aligned, and the rectangular placement area formed is exactly in contact with multiple edges of the glass to be engraved (as shown in the instruction manual). Figure 1As shown in the diagram, the glass is then placed from top to bottom within the rectangular placement area, allowing for convenient and accurate positioning of the glass. This facilitates rapid adjustment of the glass's position. Once adjusted, the vacuum adsorption component 2 securely holds the glass in place. After adsorption, the controller controls the two rectangular frames 5 to move outwards synchronously, thus moving them away from the glass. Once the rectangular frames 5 return to their initial positions, the subsequent glass engraving process can begin (as shown in the instruction manual). Figure 2 As shown in the figure, at this time the rectangular frame 5 will not interfere with the fine carving process, and the partial outer glass cut off during the fine carving process will not fall into the long hole, but will fall onto the surface of the processing table for subsequent cleaning.

[0037] During the fine carving process, water needs to be sprayed to cool the glass. At this time, some water will flow down from the elongated hole 6 and then flow through the drain hole 7 at the bottom of the processing table 1 into the collection box 8 for storage, thereby avoiding the problem of water accumulation inside the processing table 1. In addition, during the process of placing the glass into the rectangular placement area, the glass surface will come into contact with the rubber layer 9 and thus will not be worn.

[0038] Compared to existing technologies, this device uses a rectangular frame 5 and positive and negative lead screws 3 to accurately adjust and position the glass before it is adsorbed by the vacuum adsorption component 2. This eliminates the need for repeated adjustments after placement, resulting in better subsequent engraving effects.

[0039] In some embodiments, a distance sensor is embedded in the open end face of one of the rectangular frames 5, which is not shown in the figure. In this embodiment, the distance sensor can detect the distance between the two rectangular frames 5 in real time. When the distance between the two approaches 0, the distance sensor feeds a signal to the controller. Then, the controller controls the lead screw 3 to stop, thereby avoiding collision and damage to the two rectangular frames 5. When the distance between the two is about to reach the preset upper limit distance, it feeds a signal to the controller again. Then, the controller controls the lead screw 3 to stop, thereby accurately limiting the position of the rectangular frame 5 in the fine carving process, and the movement position control of the rectangular frame 5 is more accurate.

[0040] In other embodiments, a suction pump is fixed on the processing table 1, located on one side of the collection box 8 and connected to the inside of the collection box 8. The suction pump is not shown in the figure. In this embodiment, the suction pump is started immediately after the cooling water falls into the collection box 8, so that the wastewater can be transferred to other areas for discharge or purification treatment without manual transfer.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
