Description

Technical Field

[0001] This invention relates to the field of sheet metal processing equipment technology, and in particular to a multi-angle sheet metal processing equipment and processing method. Background Technology

[0002] With the rapid development of the whole-house customized furniture industry, the demand for automated and large-scale production of prefabricated panels is becoming increasingly prominent. In automated processing, panels typically undergo multiple processes such as cutting, edge banding, drilling, and grooving. The current industry practice is to immediately affix identification labels (such as QR code labels with simple diagrams) to the surface of the panels after cutting to enable information tracking and management during the production process.

[0003] For example, Chinese patent CN207841616U discloses a six-sided machining center that cuts and edges the sheet material before it enters the machine for processing. At this time, the operator needs to remove the label according to the processing position of the hole and groove and re-attach it to the unprocessed position.

[0004] However, this operation has significant technical drawbacks:

[0005] 1. Low efficiency and poor accuracy of secondary label application: Due to the high degree of uncertainty in the subsequent hole and groove machining positions (dynamically changing according to the design drawings of each board), in order to avoid damage to the labels by the drilling and milling tools during machining, operators must manually check the machining drawings displayed on the computer screen before machining, rely on experience to find the "safe area" (i.e., non-machined surface) on the board, manually tear off the original label and re-attach it. This process is not only cumbersome and time-consuming, but the accuracy of the labeling position judged manually is also difficult to guarantee, and the label is easily damaged due to positioning deviation, which may cause the label to remain on the machining path.

[0006] 2. Labels easily detach, leading to traceability failure: Existing labels mostly use ordinary adhesive methods, which are extremely prone to detachment or damage during board transfer, handling, and subsequent processes (such as high-temperature edge banding). Once a label is lost, the board loses its unique identifier, causing the production traceability chain to be interrupted. In the final assembly stage, workers need to spend a lot of time checking the drawings and actual dimensions, manually locating the installation position of missing boards, which seriously slows down assembly efficiency and may even cause quality problems such as incorrect assembly or omissions. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a multi-angle sheet material processing equipment and method. Through projection avoidance guidance, adaptive labeling mechanism, and liquid traceability code transfer technology, it achieves accurate label application and permanent traceability in a single application.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-angle sheet metal processing equipment, comprising an industrial control computer, a barcode scanner, a clamping mechanism, and a conveyor table that clamps the sheet metal through the clamping mechanism;

[0009] The barcode scanner is used to scan the QR code on the label to send the processing graphics and information of the sheet metal to the industrial control computer, which then programs the processing equipment.

[0010] A projection unit is provided on one side of the conveyor table. The barcode scanner is coupled to the projection unit through an industrial control computer. The projection unit projects the processing graphics received by the industrial control computer onto the surface of the board in a proportional manner, so that the operator can intuitively see the area where the label can be applied.

[0011] In the above scheme, preferably, the clamping mechanism is provided with a moving component for placing labels. The moving component includes a first slide rail and a first slider that cooperates with it. A second slide rail is rotatably arranged on the first slider. A second slider is provided on the second slide rail. A positioning component for placing labels is provided on the second slider.

[0012] In the above scheme, preferably, the positioning component includes a placement platform adapted to the shape of the label and a placement frame that cooperates with it. The second slider of the placement frame is fixedly provided with the positioning frame, and the placement frame is rotatably mounted on the positioning frame.

[0013] The positioning frame is equipped with an adsorption plate for adsorbing labels, and the adsorption plate is connected to a drive push rod.

[0014] In the above scheme, preferably, the positioning frame is provided with a first drive motor connected to the placement frame.

[0015] In the above scheme, preferably, the placement platform includes a liquid storage tank and a plurality of lifting rods that are lifted and lowered within the liquid storage tank;

[0016] The placement platform is fixed with a sleeve that slides with the lifting rod, and the sleeve contains an expansion fluid that can be heated and expanded.

[0017] The placement rack is equipped with a laser unit coupled to an industrial control computer. The laser unit can project the traceability code emitted by the industrial control computer into a graphic form onto the bottom of the placement platform and heat the corresponding sleeve, so that the corresponding number of lifting rods are lifted above the liquid surface of the storage tank and form the corresponding graphic.

[0018] In the above scheme, preferably, the expanding liquid is mercury or mercury.

[0019] In the above scheme, preferably, the lower end of the lifting rod is slidably disposed inside the sleeve and in contact with the expansion fluid, and the upper end, after being heated by the sleeve and expanded by the expansion fluid, slides upward and contacts the bottom of the label placed on the placement platform.

[0020] In the above scheme, preferably, the clamping mechanism is provided with a second drive motor for driving the second slide rail to rotate.

[0021] In the above scheme, preferably, the storage tank contains a colorimetric solution.

[0022] In the above scheme, a preferred method for processing sheet metal using a multi-angle sheet metal processing equipment is as follows:

[0023] S1: Move the board to the conveyor table via the clamping mechanism, and then tear off the label and place it face up on the placement table;

[0024] S2: The operator holds the barcode scanner to scan the QR code on the label, and then sends the graphic and number information of the QR code to the industrial control computer.

[0025] S3: The industrial control computer feeds back the graphic information of the QR code to the projection unit, so that the projection unit projects the board drawing onto the board surface in proportion, making it easier for operators to see the area where the label can be applied intuitively.

[0026] S4: Simultaneously with step S3, the industrial control computer uses the laser unit to irradiate the QR code number onto the sleeve at the lower end of the placement platform. The irradiated sleeve heats up under the laser irradiation, causing the corresponding expansion fluid to expand and lift the corresponding lifting rod upward.

[0027] S5: The upper end of the corresponding lifting rod passes through the liquid storage tank and coats the lower surface of the label with liquid to form a number information composed of liquid;

[0028] S6: After the first drive motor drives the placement stage to rotate, the label is positioned below the adsorption plate. At the same time, the adsorption plate is moved to the area that can be covered by the moving component, and then the adsorption plate adsorbs the label.

[0029] S7: The first drive motor drives the placement platform to reset, and then the drive push rod moves the label downward to cover the adhesive area on the board surface. The liquid number information on the bottom of the label is simultaneously combined with the board surface.

[0030] S8: When the label is lost or damaged, the liquid serial number information on the surface of the board remains on the board surface for easy traceability.

[0031] The beneficial effects of this invention are: by integrating a projection avoidance guidance system, a multi-degree-of-freedom labeling mechanism, and liquid traceability code transfer technology, this invention significantly improves the efficiency and traceability of sheet material processing.

[0032] 1. Precise labeling with zero error: The processing drawings are projected onto the board surface in proportion using a projection unit, which intuitively displays the safe labeling area, replacing the manual method of reading the drawings for positioning. This greatly improves the label avoidance accuracy and eliminates label processing damage caused by positioning deviation.

[0033] 2. Permanent traceability and anti-detachment: The laser unit triggers the thermal expansion of the expansion liquid, which pushes the lifting rod to carry the color developing liquid in the storage tank to form a coded pattern on the back of the label. After being transferred to the board, it combines with the board surface to form an invisible mark. Even if the label falls off, the source can still be traced by reading the code on the board surface with the help of a color developing instrument or solution, thus solving the problem of production chain interruption.

[0034] 3. Full-process automation: Through the coordinated control of the barcode scanner, moving components and positioning components by the industrial control computer, the entire process from information input, safe zone positioning, code generation to accurate labeling is fully automated, which greatly improves production efficiency and reduces manual labor.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-8 .

[0044] A multi-angle sheet metal processing device includes an industrial control computer 1, a barcode scanner 2, a clamping mechanism 3, and a conveyor table 4 that clamps the sheet metal via the clamping mechanism 3. The sheet metal with a label is clamped onto the conveyor table 4 via the clamping mechanism 3. Then, the operator scans the QR code on the label using the barcode scanner 2, and feeds back the sheet metal processing graphic and information on the QR code to the industrial control computer 1. Subsequently, the industrial control computer 1 programs the sheet metal processing device based on the feedback information.

[0045] A projection unit 5 is provided on one side of the conveyor platform 4, such as... Figure 1 As shown, the projection unit 5 is located on the side away from the clamping mechanism 3. The projection unit 5 can be a visualization projection device such as a laser projector, and the device is connected to the industrial control computer 1. The industrial control computer 1 projects the processing graphic of the board to be processed onto the board surface in a proportional form through the QR code graphic information fed back by the barcode scanner 2. Even if the processing graphic is projected onto the board surface in a 1:1 or near-1:1 form, it matches the processing program programmed by the industrial control computer 1, so that the operator can intuitively see the parts of the board that do not need to be processed, i.e., the area where the label can be affixed.

[0046] The clamping mechanism 3 is provided with a moving component 6 for placing labels. The moving component 6 includes a first slide rail 601 and a first slider 602 that cooperates with it. The first slider 602 is slidably disposed on the first guide rail 601. The first guide rail 601 is fixed on the clamping mechanism 3. The axis of the first guide rail 601 is spatially parallel to the material conveying direction.

[0047] The first slider 602 is rotatably provided with a second slide rail 603. Specifically, one end of the second slide rail 603 is connected to the second drive motor 13 through a rotating shaft. The second drive motor 13 can drive the second slide rail 603 to rotate relative to the first slide rail 601, thereby realizing the angle adjustment between the slide rails.

[0048] The second slide rail 603 is provided with a second slider 604, which is slidably disposed on the second slide rail 603. The second slider 604 is provided with a positioning component 7 for placing a label. After the label is placed on the positioning component 7, the positioning component 7 can be moved and positioned in any XY axis direction on the plate plane by the displacement of the first slider 602 and the second slider 604 relative to the first guide rail 601 and the second guide rail 603.

[0049] The positioning component 7 includes a placement platform 701 adapted to the shape of the label and a placement frame 702 that cooperates with it. The lower end of the placement platform 701 is fixedly connected to the plane of the placement frame 702 through support feet. The upper end of the placement platform 701 is recessed inward by 0.5-1mm to form a placement area for the label. After the operator tears off the QR code label on the circulating board, he places it in the placement area with the QR code side facing up. Then, the barcode scanner 2 is used to scan and read the data of the QR code in the placement area.

[0050] The second slider 604 is provided with a positioning frame 703, and the placement frame 702 is rotatably mounted on the positioning frame 703. Specifically, the positioning frame 703 is fixedly provided with a first drive motor 706. The drive shaft end of the first drive motor 706 is fixedly connected to the end of the placement frame 702 away from the placement platform 701. The placement frame 702 is driven to rotate by the first drive motor 706, thereby realizing the rotation of the placement platform 701 relative to the positioning frame 703.

[0051] like Figure 3 As shown, initially, the placement platform 701 is in this position. The positioning frame 703 is equipped with an adsorption plate 704 for adsorbing labels. The adsorption plate 704 is connected to a negative pressure air source and has multiple adsorption holes, so that the lower end of the adsorption plate 704 has a certain adsorption force. The adsorption plate 704 is connected to a drive push rod 705, which is fixed on the positioning frame 703. Its push rod end is fixedly connected downward to the adsorption plate 704, thereby realizing the vertical sliding of the adsorption plate 704 relative to the surface of the plate, placing the label on... Figure 3 After being placed in the placement area on the placement platform 701 shown, it is rotated to the desired position by the first drive motor 706. Figure 4 As shown in the diagram, the adsorption plate 704 can then adsorb the upper surface of the label through negative pressure, making it an integral part of the adsorption plate 704.

[0052] The placement platform 701 includes a liquid storage tank 8 and several lifting rods 9 that are raised and lowered within the liquid storage tank 8. The liquid storage tank 8 stores a color developing solution, which is transparent after drying and develops color when exposed to water. The liquid level in the liquid storage tank 8 is higher than the upper surface of the lifting rods 9 in the initial state, but lower than the end face of the placement area on the placement platform 701. That is, when the label is placed in the placement area, its lower end face will not come into contact with the liquid in the liquid storage tank 8. Specifically, the placement platform 701 faces the placement rack 7. Several sleeves 10 are fixedly installed at the bottom of the 02. The lower end of each sleeve 10 is closed, and the upper end is fixed to the placement frame 702. The lower end of the lifting rod 9 is slidably disposed at the upper end of the sleeve 10, and the sleeve 10 contains expansion fluid 11. In addition, a sliding seal such as a sealing gasket or sealing ring is provided at the mating point between the lifting rod 9 and the upper end hole of the sleeve 10, so that the expansion fluid 11 will not overflow when the lifting rod 9 slides or when the expansion fluid 11 expands. The sleeves 10 and the lifting rod 9 can form a single component, such as... Figures 6-8 As shown, the components form a rectangular array in a planar state, and the spacing between adjacent lifting rods 9 is preferably 0.3-1.5mm.

[0053] The sleeve 10 is made of glass or metal, and the expansion liquid 11 is made of mercury or mercury. After the bottom of the sleeve 10 is heated, the expansion liquid 11 expands and lifts the lifting rod 9. When multiple lifting rods 9 are lifted upwards at the same time, the protruding lifting rods can form a graphic, number or number.

[0054] The placement rack 702 is equipped with a laser unit 12 coupled to the industrial control computer 1. The laser unit 12 can be a galvanometer scanning laser or an array laser, selected according to the shape of the traceability code to be displayed. The laser unit 12 can project the traceability code emitted by the industrial control computer 1 into a graphic form onto the bottom of the placement platform 701 and heat the corresponding sleeve 10. The laser unit 12 is a laser emitter, and the laser graphic it emits has a certain amount of heat. When the graphic covers the sleeve 10, it heats the bottom of the covered sleeve 10, thereby raising the number of lifting rods 9 corresponding to the sleeve 10 to above the liquid surface of the storage tank 8 and forming the corresponding graphic. The lower end of the lifting rod 9 is slidably disposed inside the sleeve 10 and in contact with the expansion liquid 11. After the sleeve 10 is heated, the upper end expands through the expansion liquid 11 and slides upward to contact the bottom of the label placed on the placement platform 701, thereby bringing the lifting rod 9 end, which is contaminated with the color developing liquid, into contact with the bottom surface of the label. Then the placement platform 701 rotates to... Figure 3 In the indicated state, the drive push rod 705 is activated to press the label onto the applicable area on the board. At this time, the color developing liquid on the bottom of the label combines with the board and forms an invisible traceability code on the board. When the label falls off, the traceability code can be displayed by wiping it with water, which is convenient for traceability.

[0055] To prevent the liquid in the storage tank 8 from shaking or splashing onto the label when the placement platform 701 moves, a suction cylinder 101 that communicates with the inner cavity of the storage tank 8 is provided on the side of the placement platform 701 near the rotating side of the placement rack 702. A temperature control push rod 102 is provided inside the suction cylinder 101, and a piston 103 that cooperates with the suction cylinder 101 is provided at the push rod end of the temperature control push rod 102. The temperature control push rod 102 controls the movement of the piston 103 by temperature, thereby realizing the piston 103 to suction and inject the liquid in the storage tank 8.

[0056] The temperature control push rod 102 is connected to a temperature guide rod 104. A baffle plate 105 is rotatably mounted on the positioning frame 703. The baffle plate 105 has a heat-conducting strip 106 that contacts the rotated temperature guide rod 104. Figure 6 As shown, when the placement stage 701 rotates clockwise, the baffle plate 105 cooperates with the laser head of the laser unit 12 to block it. At this time, the heat of the laser head is conducted to the heat conduction strip 106. At the same time, the temperature conduction rod 104 contacts the upper surface of the heat conduction strip 106 after the placement stage 701 rotates, so that the heat conduction strip 106 conducts the temperature to the temperature conduction rod 104, and then triggers the action of the temperature control push rod 102.

[0057] Initially, such as Figure 3 In the indicated state, after placing the label on the placement platform 701 in this state, the laser unit 12 is activated. The laser unit 12 irradiates the shielding plate 105, causing the heat-conducting strip 106 to heat up. At this time, because the temperature-conducting rod 104 is in contact with the heat-conducting strip 106, the temperature control push rod 102 is activated, and the color-developing liquid in the suction cylinder 101 is gradually pushed into the storage tank 8 through the piston 103, so that the color-developing liquid wets the upper end face of the lifting rod 9. Preferably, the upper end face of the lifting rod 9 can be provided with an arc-shaped notch to facilitate the storage of the color-developing liquid, or it can be replaced by a soft cotton material with water absorption. At the same time, the first drive motor 706 drives the placement rack 702 along the... Figure 3 Rotate counterclockwise as shown, gradually until... Figure 4 In the state shown, the heat-conducting rod 104 is separated from the heat-conducting strip 106, and the laser unit 12 illuminates the sleeve 10 at the bottom of the placement platform 701. The pattern formed by the laser unit 12 gradually heats the bottom of the sleeve 10, causing the lifting rod 9 to gradually rise. After the corresponding lifting rod 9 rises, the color developing liquid at its end contacts the bottom of the label, and the upper surface of the label contacts the adsorption plate 704. The adsorption plate 704 adsorbs the label.

[0058] Subsequently, the laser unit 12 is powered off, and the liquid in the storage tank 8 is repositioned due to the separation of the heat-conducting strip 106 from the temperature-conducting rod 104, causing the temperature control push rod 102 to reset, thereby drawing the liquid back into the suction cylinder 101 for storage. After the adsorption plate 704 has adsorbed the label, the first drive motor 706 drives the placement platform 701 to rotate to... Figure 3The initial position is shown. Then, the drive push rod 705 drives the adsorption plate 704 to slide downward, and the label is applied to the applicable area on the plate to complete the secondary application.

[0059] A method for processing sheet metal using a multi-angle sheet metal processing device, the method is as follows:

[0060] S1: Move the board to the conveyor table 4 through the clamping mechanism 3, and then tear off the label and place it face up on the placement table 701;

[0061] S2: The operator holds the barcode scanner 2 to scan the QR code on the label, and then sends the graphic and number information of the QR code to the industrial control computer 1.

[0062] S3: The industrial computer 1 feeds back the graphic information of the QR code to the projection unit 5, so that the projection unit 5 projects the board drawing onto the board surface in proportion, so that the operator can see the label application area intuitively.

[0063] S4: Simultaneously with step S3, the industrial control computer 1 transmits the QR code number information to the sleeve 10 at the lower end of the placement platform 701 via the laser unit 12. The sleeve 10, which is irradiated by the laser, heats up, causing the corresponding expansion liquid 11 to expand and lift the corresponding lifting rod 9 upward.

[0064] S5: The upper end face of the corresponding lifting rod 9 passes through the liquid storage tank 8 and coats the lower surface of the label with liquid to form a number information composed of liquid;

[0065] S6: After the first drive motor 706 drives the placement stage 701 to rotate, the label is positioned below the adsorption plate 704. At the same time, the adsorption plate 704 is moved to the adhesive area by the moving component 6, and then the adsorption plate 704 adsorbs the label.

[0066] S7: The first drive motor 706 drives the placement platform 701 to reset, and then drives the push rod 705 to move the label downward and attach it to the adhesive area on the surface of the board. The liquid number information on the bottom of the label is simultaneously combined with the surface of the board.

[0067] S8: When the label is lost or damaged, the liquid serial number information on the surface of the board remains on the board surface for easy traceability.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
