Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to an automatic processing center for plastic sheets. Background Technology

[0002] In the field of plastic sheet processing, with its increasingly widespread application in industries such as construction, furniture, and electronics, the market has placed higher demands on the processing efficiency, precision, and automation of plastic sheets. However, current plastic sheet processing equipment still has many shortcomings, making it difficult to meet the needs of large-scale, high-precision production: traditional processing equipment relies heavily on manual labor for loading, unloading, and transferring sheets, which not only significantly increases the labor intensity of operators but also leads to long waiting times during process transitions, resulting in low overall processing efficiency; after being placed, the sheets are prone to displacement during cutting and other processing, leading to increased processing errors and making it difficult to guarantee product dimensional accuracy. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides an automatic processing center for plastic sheets, specifically achieved through the following technical solution: An automatic processing center for plastic sheets includes a bed, on which a gantry frame capable of reciprocating is mounted. A second slider capable of reciprocating is mounted on one side of the crossbeam of the gantry frame. A first slider capable of lifting and lowering is mounted on the second slider. A machine head is mounted at the bottom of the first slider. Two material handling mechanisms are mounted on the side of the crossbeam away from the second slider. The bed is sequentially provided with a storage area, a working area, and a unloading area. The working area is equipped with several positioning components. Several air holes are arranged in a rectangular array on the bed in the working area. The air holes are connected to a fan through pipes. The positioning components are arranged around the array of air holes.

[0004] The positioning component is a positioning cylinder, which is installed on a cylinder seat inside the bed body. The bed body has a through hole that matches the positioning cylinder.

[0005] The positioning component is a positioning cylinder. A workbench is fixedly installed in the work area. A positioning groove is provided at the edge of the workbench. A positioning column is installed at the output end of the positioning cylinder. The positioning column is located in the positioning groove.

[0006] The bed on the side of the working area facing the storage area is also equipped with a third cylinder. An electromagnet is installed at the output end of the third cylinder, and the push rod of the electromagnet slides in conjunction with an elongated hole on the bed.

[0007] The material handling mechanism includes a fixed frame fixedly installed on a crossbeam, four vertical second cylinders fixedly installed on the fixed frame, the output end of the second cylinders passing through the fixed frame and fixedly connected to the top of the lifting frame; and several suction cups fixedly installed at the bottom of the lifting frame.

[0008] Each of the air vents has a threaded sleeve fixedly installed at its bottom. A suction head is installed on the threaded sleeve. A solenoid valve is fixedly installed at the end of the suction head away from the threaded sleeve. The solenoid valve is connected to the air duct through a flexible hose. The air duct is connected to the fan through a flange.

[0009] The technical solution of this utility model has the following advantages: The automatic processing center for plastic sheets provided by this utility model integrates a bed, a movable gantry, a multi-directional adjustable slider and machine head, a dedicated material handling mechanism, and a bed partition design. It constructs a complete automated operation process for plastic sheets, from automatic feeding, precise positioning, continuous processing to automatic unloading. It effectively solves the problems of excessive manual intervention, low processing efficiency, insufficient sheet positioning accuracy, and long tool change interruption time in the processing of plastic sheets in the prior art. It significantly improves the stability, continuity and production efficiency of the processing process, while taking into account energy consumption optimization and equipment maintenance convenience. It has outstanding practicality and industrialization value.

[0010] From the perspective of the synergistic effect of specific technical features, the gantry can move along the length of the bed. In conjunction with the horizontal sliding of the second slider along the gantry beam and the lifting movement of the first slider, it can drive the machine head to achieve three-dimensional adjustment of the processing position. It can fully cover the entire working area, meet the processing needs of plastic sheets of different sizes and different processing paths, greatly expand the applicability of the equipment, and avoid the limitation of sheet size on traditional fixed processing position equipment. The two material picking mechanisms installed on the beam support four vertical second cylinders through the fixed frame, drive the lifting frame and the bottom suction cup to pick up the sheet. The guide column at the top of the lifting frame ensures the stability of the lifting process and effectively prevents the sheet from shifting or falling during transfer. Moreover, the dual material picking mechanisms can complete the loading action from the storage area to the working area and the unloading action from the working area to the unloading area in parallel or alternately, reduce the waiting time of the equipment in the process connection, and further improve the overall processing efficiency.

[0011] The structural design of the work area is crucial for ensuring processing accuracy and stability: Air holes arranged in an array on the machine bed or worktable are connected to air ducts and fans via threaded sleeves, suction heads, and solenoid valves. On one hand, the negative pressure of the fan allows for the secure fixation of the sheet metal to the work surface, fundamentally preventing processing errors caused by sheet metal displacement during processing. On the other hand, based on the actual size of the sheet metal and the processing area, the controller can selectively open the solenoid valves at corresponding locations, adsorbing only the air holes in the area covered by the sheet metal, rather than ventilating the entire area, effectively reducing fan energy consumption. Simultaneously, the fan's back-blowing function can periodically clean the air holes. Residual dust or waste inside prevents pore blockage from affecting the adsorption effect, extends equipment maintenance cycle, and reduces maintenance costs. The positioning components set around the pore array can form precise limits from the side of the plate. Together with the pushing mechanism on the side of the working area facing the storage area, the plate can be smoothly pushed from the initial placement position to the processing reference position defined by the positioning components. The design of the push rod extending when the electromagnet is energized and retracting when the power is cut off avoids the push rod being exposed for a long time and interfering with the plate transfer process. This further improves the positioning accuracy and the smoothness of equipment operation, ensures that the processing reference of each plate is consistent, and reduces batch processing errors.

[0012] In addition, the tool magazine mechanism at the top of the crossbeam drives the slide plate through the first cylinder to move the straight tool magazine, which can quickly cooperate with the machine head to complete the automatic tool changing action. Compared with traditional manual tool changing or fixed tool magazine, it significantly shortens the tool changing interruption time, ensures the continuity of the machining process, and reduces the efficiency loss caused by tool changing interruption. At the same time, all moving parts are uniformly coordinated and controlled by the controller, further reducing the intensity of manual operation and avoiding the impact of human operation errors on machining quality.

[0019] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] As attached Figure 1 and attached Figure 2 As shown, this utility model provides an automatic processing center for plastic sheets, including a bed 1, on which a gantry 3 capable of moving back and forth along its length is installed.

[0021] A second slider 6 that can slide back and forth along the crossbeam is slidably installed on one side of the gantry frame 3. A first slider 4 that can be raised and lowered is installed on the second slider 6. A machine head is installed at the bottom of the first slider 4.

[0022] The methods for driving the second slider 6 and the first slider 4 to move are existing technologies and will not be described in detail here.

[0023] Two material handling mechanisms 2 are installed on the side of the crossbeam away from the second slider 6.

[0024] The bed 1 is provided with a material storage area, a work area and a material unloading area in sequence.

[0025] The material handling mechanism 2 can move the sheet material from the storage area to the working area and the unloading area.

[0026] The top of the crossbeam is equipped with a tool magazine mechanism 7 that works with the head.

[0027] The structure of the tool magazine mechanism 7 is shown in the attached figure. Figure 3 It includes a plate base 9, which is bolted to the bottom of the crossbeam.

[0028] A first cylinder 8 is bolted to one end of the plate base 9; a slide plate 11 is slidably installed on the bottom of the plate base 9, that is, on the side away from the crossbeam, and the output end of the first cylinder 8 is fixedly connected to the slide plate 11.

[0029] A straight-line tool magazine 10 is fixedly installed at one end of the slide plate 11 near the first slider 4.

[0031] Four vertical guide columns 14 are fixedly installed on the top of the lifting frame 15, and the guide columns 14 slide in conjunction with the fixed frame 12.

[0032] In this embodiment, the bed 1 in the working area has several air holes 5 arranged in a rectangular array. The air holes 5 are connected to the fan through pipes. When the board is placed in the working area, the fan is started and the board is adsorbed onto the bed 1.

[0033] When the fan blows back, the air vent 5 can be cleaned.

[0034] As attached Figure 2 and attached Figure 5 As shown, the work area is also equipped with several positioning components, which are distributed in a U-shape, meaning that positioning components are installed on all sides of the work area except the side facing the storage area.

[0035] In this embodiment, the positioning component is a positioning cylinder 18. The bed 1 has a through hole that matches the positioning cylinder 18. When the plate needs to be positioned, the output end of the positioning cylinder 18 extends out from the through hole.

[0036] When the positioning cylinder 18 is not in use, the top of its output end is flush with the top of the bed 1.

[0037] In this embodiment, the air holes 5 are divided into two groups, and each group of air holes 5 corresponds to a material handling mechanism 2. A positioning cylinder 18 is installed on the bed 1 between the two groups of air holes 5.

[0038] The positioning cylinder 18 is fixedly installed on the cylinder seat 19 inside the bed 1.

[0043] When the plate needs to be positioned, the output end of the positioning cylinder 18 rises, the electromagnet 25 is energized, the push rod 24 extends out from the elongated hole 26, and then the third cylinder 22 is activated, driving the push rod 24 to push the plate into place. Then the electromagnet 25 is de-energized, and the third cylinder 22 drives the electromagnet 25 back to its original position.

[0044] In this embodiment, each set of air holes 5 corresponds to two pusher mechanisms 17.

[0045] This utility model also provides another embodiment of the automatic processing center for plastic sheets. The difference between this embodiment and the previous embodiment is that a worktable 30 is fixedly installed in the work area, and a positioning groove 31 is opened at the edge of the worktable 30. A positioning column 32 is installed in the positioning groove 31, and the positioning column 32 is installed at the output end of the positioning cylinder 18.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
