Description

Technical Field

[0001] This utility model belongs to the field of loading and unloading equipment, and in particular relates to a pre-processing mechanism for loading materials for a precision engraving machine. Background Technology

[0002] A CNC engraving machine is a type of CNC machine tool used for grinding, cutting, and other processing of glass products. It is a key piece of equipment in tempered glass film processing. The raw material for tempered glass film is glass, which is cut into small pieces and stacked together for loading. During the loading process, multiple pieces of glass may adhere but not separate. Current technology uses vibration and air blowing to avoid this. However, for small processing units that lack cleanrooms or whose cleanrooms are only used in the later stages of processing, using vibration and air blowing can introduce dust between or onto the glass, damaging the glass surface. Utility Model Content

[0003] The purpose of this utility model is to provide a pre-treatment mechanism for feeding materials into a CNC engraving machine, so as to solve the problems of multiple pieces of materials adhering to each other and being difficult to separate, and easily causing damage to the surface of glass materials in existing CNC engraving machines.

[0004] To solve the above problems, this utility model discloses a pre-processing mechanism for feeding materials into a precision engraving machine, comprising: Material storage rack, used to hold several stacked materials; Conveyor lines are used to transport materials; The first suction mechanism is used to transfer materials from the material placement rack to the conveyor line; The second suction mechanism is located on one side of the conveyor line, with the working end of the first suction mechanism facing downwards and the working end of the second suction mechanism facing upwards.

[0005] As a further improvement to the above technical solution: The material placement rack includes a limiting frame, a slide mounted on the limiting frame, and a lifting mechanism. The slide is slidably mounted on the limiting frame, and the lifting mechanism is connected to the slide to drive the slide to rise and fall.

[0006] The conveyor line includes a movable platform, a slide rail, and a moving drive component. The movable platform is slidably engaged with the slide rail, and the moving drive component is connected to the movable platform to drive the movable platform to move. A feeding fixture is provided on the movable platform.

[0007] The first suction mechanism includes a telescopic mechanism, a first suction nozzle, a horizontal frame, and a horizontal drive mechanism disposed on the horizontal frame. The horizontal drive mechanism is connected to the telescopic mechanism, and the first suction nozzle is disposed at the output end of the telescopic mechanism.

[0008] The second suction mechanism includes a second suction nozzle, the suction force of which is less than that of the first suction nozzle.

[0009] The second suction mechanism also includes a third suction nozzle, the height of which is greater than the height of the second suction nozzle. This arrangement is designed to accommodate materials with different numbers of adherent layers.

[0010] The conveyor line also includes a fixture loading mechanism and a fixture unloading mechanism.

[0011] The movable platform includes a cutout frame, a clamping frame, and a clamping driver. The clamping frame is disposed on both sides of the cutout frame, and the clamping driver is connected to the clamping frame.

[0012] Both the fixture loading mechanism and the fixture unloading mechanism include a lifting drive mechanism, a slide rail frame, and a positioning tray. The lifting drive mechanism is connected to the slide rail frame, and the positioning tray is slidably engaged with the slide rail frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a mechanical separation structure. Through the rotation and lifting action of the first suction mechanism, combined with the auxiliary suction of the second suction mechanism, the physical separation of adhering materials is achieved. It integrates automatic material lifting, suction, separation, conveying, and automatic loading and unloading functions of fixtures, forming a complete automated pre-processing solution for material feeding. The lifting mechanism of the material placement rack automatically compensates for the material height, ensuring accurate suction positioning; the conveyor line and suction mechanism work together to achieve continuous and stable material supply, significantly improving feeding efficiency and the overall automation level of the line.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown, the pre-processing mechanism for loading materials into the engraving machine in this embodiment includes: Material placement rack 1 is used to place several stacked materials; such as Figure 2As shown, the material placement rack 1 includes a limiting frame 11, a slide 13 disposed on the limiting frame 11, and a lifting mechanism 12. The slide 13 is slidably disposed on the limiting frame 11, and the lifting mechanism 12 is connected to the slide 13 to drive the slide 13 to rise and fall.

[0021] Conveyor line 2 is used for conveying materials; such as Figure 3 As shown, conveyor line 2 includes a movable platform 21, a slide rail 22, and a moving drive component 23. The movable platform 21 is slidably engaged with the slide rail 22, and the moving drive component 23 is connected to the movable platform 21 and is used to drive the movable platform 21 to move. A feeding fixture 20 is provided on the movable platform 21. The moving drive component 23 is used to drive the movable platform 21 to move, and its structure can adopt a screw and slider structure, or a linear mechanism such as a cylinder and slider. Figure 4 As shown, the movable table 21 includes a cutout frame 211, a clamping frame 212, and a clamping driver 213. The clamping frame 212 is disposed on both sides of the cutout frame 211, and the clamping driver 213 is connected to the clamping frame 212. Since the cutout frame 211 is located in the middle of the movable table 21, the moving drive component 23 should be disposed on the side of the movable table 21 to avoid affecting the loading and unloading of the cutout frame 211.

[0022] The first suction mechanism 3 is used to transport materials from the material placement rack 1 to the conveyor line 2; for example... Figure 5 As shown, the first suction mechanism 3 includes a telescopic mechanism 31, a first suction nozzle 32, a transverse frame 33, and a transverse drive mechanism 34 mounted on the transverse frame 33. The transverse drive mechanism 34 is connected to the telescopic mechanism 31, and the first suction nozzle 32 is located at the output end of the telescopic mechanism 31. A rotation mechanism can also be provided between the telescopic mechanism 31 and the first suction nozzle 32, which can assist in the separation of the attached material by rotating the angle. The rotation mechanism can be a servo motor, a rotary cylinder, or other angle rotation mechanism. There are no requirements for the rotation angle and rotation speed here; as long as there is a rotational tendency to assist in material separation, it is sufficient.

[0023] The second suction mechanism 4 is located on one side of the conveyor line 2, with the working end of the first suction mechanism 3 facing downwards and the working end of the second suction mechanism 4 facing upwards. The second suction mechanism 4 includes a second suction nozzle 41, the suction force of which is less than that of the first suction nozzle 32.

[0024] like Figure 6As shown, conveyor line 2 also includes a fixture loading mechanism and a fixture unloading mechanism. Both mechanisms include a lifting drive mechanism 51, a slide rail frame 52, and a positioning tray 53. The lifting drive mechanism 51 is connected to the slide rail frame 52, and the positioning tray 53 is slidably engaged with the slide rail frame 52. The fixture loading mechanism loads fixtures into the hollow frame 211 of the movable table 21, and the fixture unloading mechanism unloads the fixtures filled with materials for further processing. The lifting drive mechanism 51 drives the slide rail frame 52 to move up or down. Its structure can employ a lead screw drive structure, hydraulic cylinder, pneumatic cylinder, or other linear motion mechanism. The positioning tray 53 and the slide rail frame 52 are slidably engaged, similar to a drawer structure. Pulling out the positioning tray 53 completes the fixture loading or unloading. A positioning switch is installed on the slide rail frame 52; the lifting step can only be performed after the positioning tray 53 has reached its designated position.

[0025] like Figure 7 As shown, the second suction mechanism 4 also includes a third suction nozzle 42, the height of which is greater than the height of the second suction nozzle 41.

[0026] In use, the sheet material is stacked and placed in the limiting frame 11 and supported on the slide 13. The lifting mechanism 12 drives the slide 13 to move upward, so that the material moves upward. A position detection switch should be set at the top of the limiting frame 11. When the lifted material reaches the position detection switch, the lifting mechanism 12 stops working. The lifting mechanism 12 adopts a screw lifting mechanism, cylinder lifting mechanism or other lifting mechanism and should have a precise lifting function.

[0027] If the material is defined as 4mm, it will be lifted 4mm, with the upper end of the material protruding beyond the limit frame, allowing for material suction. At this point, the lifting mechanism 12 will lift 4mm upwards. When the material reaches the position detection switch, the lifting mechanism 12 will stop operating, completing the lifting process. After lifting, the first suction nozzle 32 of the first suction mechanism 3 will suck up the first piece of material. To help the material detach, the lifting mechanism 12 will descend 4mm to its initial position. Due to gravity, the unstable material will detach on its own. The lifting mechanism 12 continues to move upward. The upward stroke is used to determine the material adsorption status (if it moves upward 4mm to the position detection switch sensing position, the material is in a normal state; if it moves upward 8mm to the position, it is considered that two pieces of material are adhered together; if it moves upward 12mm to the position, it is considered that three pieces of material are adhered together. Due to weight limitations, after multiple tests, it was found that the maximum number of pieces of material adhering together is 3). If the lifting mechanism 12 stroke is 4mm, the second suction nozzle 41 and the second suction nozzle 42 do not need to work, and the material is directly sent to the fixture 20 of the conveyor line 2; if the lifting mechanism 12 stroke is 8mm, the third suction nozzle 42 works. Here, the height difference between the second suction nozzle 41 and the third suction nozzle 42 is 4mm. The height of the third suction nozzle 42 is 4mm lower than the suction position, and the second suction nozzle 41 is 24mm below the third suction nozzle 42. The third suction nozzle 42 picks up the next piece of material from the two adhered pieces. To facilitate detachment, after the third suction nozzle 42 picks it up, the rotating mechanism above the first suction nozzle 32 drives the upper piece of material to rotate, while the telescopic mechanism 31 moves upward by 2mm. The upper and lower pieces of material detach, and the upper piece of material returns to its initial angle and height, delivering the material to the fixture 20. It should be noted that the above-mentioned dimensional limitations are only one embodiment, and more dimensions can be used. If the lifting mechanism 12 has a stroke of 12mm, both the second and third suction nozzles 41 and 42 will operate. The material will first be transported above the second suction nozzle 41, and the rotating mechanism will rotate first, detaching the bottom piece of material by twisting. At this time, it is possible that both bottom pieces of material will detach. In this case, the third suction nozzle 42 will not work, and a warning instruction is given here. If only the bottom piece of material is detached, the middle piece of material will detach from the third suction nozzle 42, and the top piece of material will be delivered to the fixture 20. If there are multiple pieces of material, the material from the second suction nozzle 41 and the material from the third suction nozzle 42 are transported to the fixture according to the instructions (there is no specific order here, but the second suction nozzle 41 is generally prioritized). When both pieces of material are on the second suction nozzle 41, the first suction nozzle 32 picks them up, twists them, and then separates them upwards before sending the material to the fixture. This invention can intelligently determine whether the material is a single sheet, two sheets, or three sheets stuck together by changing the stroke of the lifting mechanism. For different situations, the system will call the first, second, and third suction nozzles to perform corresponding separation actions (such as rotation, lifting, and auxiliary suction), effectively preventing multiple pieces of material from being stacked and entering the engraving machine, thereby ensuring processing accuracy and product yield.

[0028] The working process of the fixture loading and unloading mechanisms is as follows: the clamping driver 213 drives the clamping frame 212 to move to both sides, so that the cutout frame 211 has a through hole. The lifting drive mechanism 51 drives the fixture 20 to move upward and pass through the cutout frame 211. The clamping driver 213 drives the clamping frame 212 to clamp the fixture 20. After loading is completed, the moving drive component 23 drives the moving platform 21 to the unloading area. The lifting drive mechanism 51 drives the positioning tray 53 to move upward and press against the fixture 20. The clamping driver 213 drives the clamping frame 212 to release the restriction on the fixture 20. The lifting drive mechanism 51 drives the positioning tray 53 to move downward. The fixture 20 can be unloaded by pulling out the positioning tray 53 (when used in the workshop, a box is installed, not shown here. The positioning tray 53 is pulled out by opening a fixture loading hole and a fixture unloading hole on the box).

[0029] The entire process requires no vibration or air blowing, eliminating the risk of dust contamination and surface scratches at the source, making it especially suitable for small processing units with limited cleanroom conditions.

[0030] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
