Description

Technical Field

[0001] This invention relates to the field of sheet metal manufacturing technology, and in particular to a sheet metal patch cutting device. Background Technology

[0002] The raw material for engineered wood products is wood. Wood itself often has defects such as knots or wormholes, which will appear on the surface of the engineered wood products after they are made into products, affecting their appearance and sales, and ultimately making them substandard products.

[0003] The existing technology involves punching and filling holes. First, the location of the knot or wormhole is punched out, and then a piece of board of the same size without knots or wormholes is used to fill it, so that the board is defect-free. This process is called cut-and-fill.

[0004] During the patching process, workers move the boards to the platform, identify how many galls and wormholes need to be patched, and then place the areas to be patched under the machine for patching.

[0005] Because there are many areas that need to be excavated and repaired during the patching process, the following defects and shortcomings exist:

[0006] ① Manual identification is difficult, and there are always missed locations, leading to rework. ② During the patching process, the operator's hands are close to the patching machine head, increasing the risk of injury. ③ During the patching process, the area to be patched is often not aligned with the patching machine head, resulting in inaccurate patching. ④ Patching work is labor-intensive, and the accuracy and pass rate of manual patching cannot be guaranteed. ⑤ The patching process involves repeatedly finding defects, patching, and inspecting. This repeated process results in slow patching speed and extremely low work efficiency. ⑥ During the patching process, wood chips need to be handled, placed on the machine one by one for patching, and then placed back one by one. This process can cause bumps and knocks, and because the wood chips are thin, handling individual chips can cause tearing at the edges, greatly reducing the product pass rate. Summary of the Invention

[0007] To address the aforementioned problems, the present invention aims to provide a sheet metal cutting and patching device for sheet metal, which can improve production efficiency.

[0071] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0072] like Figure 1 and Figure 2 As shown, the present invention provides a patching device for sheet metal, including a frame 1, a sheet metal conveying unit 2, a sheet metal defect detection unit 3, a patching and feeding unit 4, a head unit, and a control unit. The sheet metal conveying unit 2, the sheet metal defect detection unit 3, the patching and feeding unit 4, and the head unit are respectively connected to the control unit to achieve automatic identification, automatic removal, and automatic filling of defects during the conveying of sheet metal 7. The control unit can be a PLC controller.

[0073] like Figure 3 As shown, the frame 1 includes a cubic frame body 1-1, a support frame 1-2 installed inside the frame body 1-1 for mounting the sheet material conveying unit 2, and a lifting bracket 1-3 for mounting the machine head unit. The front and rear ends of the frame body 1-1 are through-holes for the sheet material 7 to pass through. Door panels 1-4 are provided on the lower left and right sides of the frame body 1-1, and observation windows 1-5 are installed on the upper part. Multiple adjustable feet 1-6 are provided at the bottom of the frame body 1-1, which is prior art. The height of the frame body 1-1 can be adjusted by adjusting the feet 1-6.

[0074] like Figure 4 As shown, the sheet material conveying unit 2 includes a belt conveyor mechanism and multiple sheet material positioning components disposed on both sides of the belt conveyor mechanism. The belt conveyor mechanism includes a conveyor bracket 2-1 fixed on a support frame, a drive roller 2-2 rotatably disposed at one end of the conveyor bracket 2-1, a driven roller 2-3 rotatably disposed at the other end of the conveyor bracket 2-1, a drive motor 2-4 mounted on the conveyor bracket 2-1 and driven by the drive roller 2-2, and a conveyor belt 2-5 supported on the drive roller 2-2 and the driven roller 2-3. The drive motor 2-4 is mounted on a motor mounting plate on the side of the conveyor bracket 2-1. The drive motor 2-4 is driven by the drive roller 2-2 via a chain and gears. The drive motor 2-4 is a servo motor and is signal-connected to the control unit, which can precisely control the moving distance of the sheet material, moving it from the feeding position where the sheet material identification unit 3 is located to the head unit position.

[0075] To facilitate adjustment of the tension of the conveyor belt 2-5, the driven roller 2-3 is adjustable. Figure 5As shown, an adjusting support 2-1a is provided at one end of the conveyor bracket 2-1. The roller shaft of the driven roller 2-3 is installed on the adjusting support 2-1a via the adjusting bolt 2-1b. The position of the driven roller 2-3 can be adjusted by rotating the adjusting bolt 2-1b, thereby adjusting the tension of the conveyor belt 2-4.

[0076] The plate positioning assembly includes a support base 2-6 fixed on the support frame 2-1, a plate positioning drive component 2-7 mounted on the support base 2-6, a plate clamping plate 2-8 connected to the plate positioning drive component 2-7, and a buffer strip 2-9 fixed on the side of the plate clamping plate 2-8 near the belt conveyor mechanism. The plate positioning drive component 2-7 is a cylinder. The plate clamping plate 2-8 is moved to both sides of the plate to clamp the plate and fix it, thereby facilitating the machine head unit to perform patching operations on the plate.

[0077] like Figure 2 As shown, the sheet metal defect detection unit 3 is mounted on the frame 1 and located at the feed end of the sheet metal conveying unit 2. It is used to detect defects on the sheet metal 7 and includes a camera recognition mechanism mounted on top of the frame 1 and a light source mechanism 3-2 located below the camera recognition mechanism. The camera recognition mechanism includes two camera recognition components 3-1 arranged at intervals, such as... Figure 6 As shown, each camera identification component 3-1 includes a camera protective cover 3-1a, a camera mounting plate 3-1b fixed inside the camera protective cover 3-1a, a line scan camera 3-1c mounted on the camera mounting plate 3-1b, and a protective cover cover 3-1d that cooperates with the camera protective cover 3-1a. The line scan camera 3-1c is signal-connected to the control unit. The line scan camera 3-1c transmits the image information of the monitored plate 7 to the control unit. The control unit can calculate the defect location on the plate 7 and issue a command to the head unit 6 so that the head unit 6 moves to the location that needs to be repaired. The method by which the control unit calculates the defect location on the plate 7 is existing technology and will not be described in detail in this invention.

[0078] like Figure 7 As shown, the light source mechanism 3-2 includes two boom assemblies detachably mounted on the frame 1 and a light source 3-2e mounted between the two boom assemblies. The boom assembly includes a height adjustment plate 3-2a, a boom 3-2c fixedly connected to the height adjustment plate 3-2a, a light source connector 3-2c with an adjustable angle mounted on the boom 3-2b, and a light source connecting plate 3-2d fixedly connected to the light source connector 3-2c. The light source connecting plate 3-2d is fixedly connected to the light source 3-2e. The light source connector 3-2c is mounted on the boom 3-2c via a support shaft, which is locked by a nut. The height adjustment plate 3-2a has two oblong holes arranged vertically for bolts to pass through. The height of the light source 3-2e is adjusted by adjusting the position of the bolts in the oblong holes.

[0079] The chip loading unit 4, mounted on the frame 1 and located on the side of the board conveying unit 2, is used for loading chips, such as... Figures 8 to 10 As shown, the system includes a feeding mechanism 4-1, a material separating mechanism 4-2 located at the discharge end of the feeding mechanism 4-1, a feeding mechanism 4-3 located opposite to the material separating mechanism 4-2, a punching mechanism 4-4 located at the discharge end of the feeding mechanism 4-3, a patch gripping station 4-5 located at the discharge end of the punching mechanism 4-4, and a patch gripping mechanism 4-6 located corresponding to the patch gripping station 4-5. The material separating mechanism 4-2 separates the patch material 4-1i from the feeding mechanism 4-1 and transfers it to the punching mechanism 4-4 via the feeding mechanism 4-3. The patch gripping mechanism 4-6 transfers the patch obtained by the punching mechanism 4-4 to the patch gripping station 4-5. The material separating mechanism 4-2, the feeding mechanism 4-3, the punching mechanism 4-4, the patch gripping mechanism 4-6, and the patch gripping station 4-5 are mounted on the frame 1 via a feeding mounting plate 4-7.

[0080] like Figure 11 As shown, the feeding mechanism 4-1 includes a feeding support plate 4-1a fixed to the lower part of the frame 1, a feeding drive component 4-1b installed at the lower end of the feeding support plate 4-1a, two sets of feeding guide columns 4-1c vertically fixed to the upper end of the feeding support plate 4-1a, and a raw material bin that slides with the feeding guide columns 4-1c. The raw material bin is connected to the feeding drive component 4-1b and moves up and down under the drive of the feeding drive component 4-1b. Two sets of feeding guide columns 4-1c are respectively arranged at the inlet and outlet positions of the hopper. Each set of feeding guide columns 4-1c includes two feeding guide columns 4-1c arranged opposite each other, a connecting plate 4-1d connecting the upper ends of the two feeding guide columns 4-1c, and a feeding detection component 4-1e installed on the connecting plate 4-1d. The feeding detection component 4-1e adopts a photoelectric sensor. The feeding detection component 4-1e and the feeding drive component 4-1b are respectively connected to the control unit. When the feeding detection component 4-1e detects that there is raw material in the hopper, the control unit controls the feeding drive component 4-1b to lift the raw material hopper upward to feed the material.

[0081] To improve the strength of the structure, a reinforcing plate 4-1h is connected between the feeding support plate 4-1a and the frame 1.

[0082] The raw material silo includes a silo bottom plate 4-1f and two silo side plates 4-1g that are fixed to the silo bottom plate 4-1f. A space is formed between the two silo side plates 4-1g for the patch material 4-1i to pass through. The patch material 4-1i passes through the two feeding guide column assemblies and the raw material silo in a long strip shape.

The material dispensing drive component 4-2b is a cylinder, and the material dispensing detection component 4-2e is a photoelectric sensor. The material dispensing drive component 4-2b and the material dispensing detection component 4-2e are respectively connected to the control unit. The material dispensing suction cup assembly includes a suction cup mounting plate 4-2c and two material dispensing suction cups 4-2d mounted on the suction cup mounting plate 4-2c.

[0084] like Figure 13 As shown, the feeding mechanism 4-3 includes a feeding linear module 4-3a mounted on the loading mounting plate 4-7 and a feeding assembly connected to the feeding linear module 4-3a. The feeding assembly is driven by the linear movement of the feeding linear module 4-3a to transfer the patch material 4-1i to the punching mechanism 4-4. The feeding linear module 4-3a adopts the ball screw type linear movement module in the prior art, model XEH6-Lx-C-S250-BC-P10-D3. The specific structure will not be described in detail in this invention.

[0085] The feeding assembly includes a rotary cylinder 4-3b connected to the slide of the linear feeding module 4-3a, a gripper cylinder 4-3c connected to the rotary cylinder 4-3b, and a feeding detection component 4-3d mounted on the gripper cylinder 4-3c. A waste discharge channel 4-8 corresponding to the gripper cylinder 4-3c is also fixed on the loading mounting plate 4-7. The feeding detection component 4-3d is a photoelectric sensor. The rotary cylinder 4-3b, the gripper cylinder 4-3c, and the feeding detection component 4-3d are respectively connected to the control unit for signal transmission. When the material 4-1i gripped by the gripper cylinder 4-3c is not long enough (the gripper cylinder 4-3c grips the material 4-1i to the punching mechanism 4-4 and then retracts a certain distance; when the feeding detection component 4-3d cannot detect the material 4-1i, it indicates that the material 4-1i is not long enough), the rotary cylinder 4-3b drives the gripper cylinder 4-3c to rotate and releases the material 4-1i to the waste discharge channel 4-8.

[0086] like Figure 14 As shown, the blanking mechanism 4-4 includes a blanking mounting plate 4-4a fixed on the feeding mounting plate 4-7, a blanking lower die 4-4b mounted on the blanking mounting plate 4-4a, a raw material positioning component mounted on the blanking mounting plate 4-4a and located at the feeding end of the blanking lower die 4-4b, a blanking upper die assembly that slides with the blanking mounting plate 4-4a, and a blanking drive component 4-4c mounted between the blanking mounting plate 4-4a and the blanking upper die assembly.

[0087] The upper die assembly for blanking includes two blanking guide posts 4-4d that slide in conjunction with the blanking mounting plate 4-4a, a first connecting plate 4-4e connecting the upper ends of the two blanking guide posts 4-4d, a second connecting plate 4-4f connecting the lower ends of the two blanking guide posts 4-4d, and a punch 4-4g fixed to the lower end of the first connecting plate 4-4e and engaging with the lower die 4-4b. The blanking drive component 4-4c is installed between the blanking mounting plate 4-4a and the second connecting plate 4-4f. The blanking drive component 4-4c uses an AirTAC multiplier cylinder, model SDAT80x100x20SB.

[0088] like Figure 15 As shown, the lower die 4-4b has a through slot 4-4b1 extending through the feeding direction and a punch slot 4-4b2 with an opening at the top. The punch 4-4g matches the punch slot 4-4b2 and can extend into the punch slot 4-4b2 to punch the patch material 4-1i. In this example, the patch needs to be punched into a waist-hole type, therefore, as Figure 16 As shown, the punch 4-4g has two symmetrically arranged semi-circular grooves 4-4g1, and correspondingly, the punch groove on the lower die 4-4b cooperates with the punch 4-4g. The patch gripping station 4-5 has a limiting groove for placing the patch 4-9, which corresponds to the outlet of the through slot 4-4b1 on the lower die 4-4b. Figure 17 As shown, the punch first punches out a semi-circular structure at the head end of the patch material 4-1i. The feeding linear module 4-3a moves the patch material 4-1i forward a certain distance. The punch punches out another semi-circular structure and the semi-circular structure of the next patch on the patch material 4-1i.

[0089] The raw material positioning assembly includes a positioning base 4-4h with a positioning slot, a positioning block 4-4i disposed within the positioning slot, a positioning drive component 4-4j mounted on the positioning base 4-4h and connected to the positioning block 4-4i for transmission, and a blanking detection component 4-4k mounted on the positioning base 4-4h and located at the feed end of the positioning slot. The positioning drive component 4-4j is a cylinder, and the blanking detection component 4-4k is a photoelectric sensor. The positioning drive component 4-4j, the blanking detection component 4-4k, and the blanking drive component 4-4c are respectively connected to the control unit for signal transmission. When the blanking detection component 4-4k detects the positioning base... When there is a patch material 4-1i within 4-4h, the punching drive component 4-4c is controlled to perform a punching action. At the same time, the length of patch 4-9 is controlled by the stroke of the feeding linear module 4-3a. For example, if the length of patch 4-9 is 50mm, the stroke of the feeding linear module 4-3a is 50+15mm. When the gripper cylinder 4-3c moves the patch material 4-1i to the position of the material positioning component, the positioning drive component drives the positioning block 4-4i to move down to fix the patch material 4-1i. The feeding linear module 4-3a moves back 50+15mm. After the patch at the front end is punched, the patch material 4-1i continues to be moved.

[0090] like Figure 18 As shown, the patch gripping mechanism 4-6 includes a gripping base 4-6a fixed on the loading mounting plate 4-7, a first gripping drive component 4-6b mounted on the gripping base 4-6a, a second gripping drive component 4-6c driven by the first gripping drive component 4-6b, and a gripping suction cup assembly driven by the second gripping drive component 4-6c. The second gripping drive component 4-6c moves horizontally under the drive of the first gripping drive component 4-6b, and the gripping suction cup assembly moves vertically under the drive of the second gripping drive component 4-6c. The suction cup gripping assembly includes a suction cup connecting plate 4-6d and a gripping suction cup 4-6e mounted on the suction cup connecting plate 4-6d. The first gripping drive component 4-6b and the second gripping drive component 4-6c are pneumatic cylinders.

[0091] The machine head unit includes a machine head moving mechanism and a machine head mechanism mounted on the machine head moving mechanism. The machine head moving mechanism drives the machine head mechanism to move to the position on the plate that needs to be patched.

[0092] like Figure 19 As shown, the machine head moving mechanism 5 includes two first linear modules 5-1 for driving the machine head mechanism to move along the X-axis direction, a second linear module 5-2 for driving the machine head mechanism 6 to move along the Y-axis direction, and a lifting module 5-3 for driving the machine head mechanism 6 to move along the Z-axis direction.

[0093] The first linear module 5-1 adopts the ball screw type linear motion module in the prior art, model TPGB10-L224-S1400+300-R-H1.5KW-D3-N20-B2. The two first linear modules 5-1 are connected to the same module drive motor via a connecting shaft.

[0094] The second linear module 5-2 adopts the existing ball screw type linear motion module, model TPHB22-L250-S2600-L-H75-T3-N15-Y(3M25_X2_9f7f_X0_).

[0095] The lifting module 5-3 adopts the existing ball screw type linear movement module, model TPSK15-L2510-C-S200-BC-H75B-D3_200.

[0096] To facilitate the limiting of the head mechanism 6, buffers 5-4 are provided at both ends of the second linear module 5-2. The buffer 5-4 includes a buffer support and a spring set on the buffer support.

[0097] like Figure 20 and Figure 21 As shown, the head mechanism 6 includes a milling fixed plate 6-1 that is connected to the lifting module 5-3, a milling spindle 6-2 mounted on the milling fixed plate 6-1, a patch picking assembly and a patch clamping assembly mounted on one side of the milling spindle 6-2, and a staple gun assembly mounted on the other side of the milling spindle 6-2.

[0098] The chip pick-up assembly is used to pick up the chip 4-9 from the chip pick-up station and place it at the defect location on the board 7. It includes a chip pick-up suction cup 6-3 and a pick-up drive component 6-4 that is connected to the chip pick-up suction cup 6-3. The pick-up drive component 6-4 is a cylinder that drives the chip pick-up suction cup 6-3 to move vertically. Specifically, the pick-up drive component 6-4 is connected to a vacuum connector 6-6 via a suction cup connector 6-5. The vacuum connector 6-6 is connected to the chip pick-up suction cup 6-3.

[0099] The patch clamping assembly includes a pressure plate 6-7 and a pressure plate driving component 6-8 that is connected to the pressure plate 6-7. The pressure plate driving component 6-8 is a cylinder that drives the pressure plate 6-7 to move up and down, thereby clamping the patch 4-9.

[0100] The staple gun assembly includes a staple gun mounting plate 6-9 fixedly connected to a milling fixing plate 6-1, a staple gun drive component 6-10 fixed on the staple gun mounting plate 6-9, a staple gun 6-11 driven by the staple gun drive component 6-10, a hopper base 6-12 connected to the staple gun hopper, a staple hopper 6-13 set on the hopper base 6-12, a pusher drive component 6-14 installed on the side of the hopper base 6-12, and a pusher component 6-15 passing through the hopper base 6-12 and driven by the pusher drive component 6-14. The pusher component 6-15 pushes the resin staples 6-13a falling from the staple hopper 6-13 into the staple gun hopper under the drive of the pusher drive component 6-14. A staple detection component is provided on the bottom side of the staple hopper 6-13. The staple detection component uses a photoelectric sensor to detect whether there are resin staples in the staple hopper 6-13 and transmit the signal to the control unit. When there are no resin staples in the staple hopper, the staff is reminded to add resin staples.

[0101] like Figure 22 and Figure 23 As shown, the handle of the staple gun 6-11 is mounted on the support plate of the power output end of the staple gun drive component 6-10 via the upper pressure block 6-17 and the lower pressure block 6-18. The upper pressure block 6-17 and the lower pressure block 6-18 are set separately and have corresponding handle limiting grooves. The handle of the staple gun 6-11 is placed between the upper pressure block 6-17 and the lower pressure block 6-18 and locked with bolts. The staple hopper 6-13 is limited in the mounting groove on the hopper base 6-12 and fixed with the staple gun pressure plate 6-19.

[0102] The staple gun drive component 6-10 and the pusher drive component 6-14 are pneumatic cylinders connected to the control unit. The pusher drive component 6-14 is connected to the pusher component 6-15 via the pusher connecting plate 6-16. When the pusher drive component 6-14 retracts, the resin staples 6-13a in the staple hopper 6-13 fall onto the hopper base 6-12. The pusher drive component 6-14 drives the pusher component 6-15 to move towards the staple gun hopper 6-13, pushing the resin staples 6-13a into the staple gun hopper 6-13. Then, the staple gun drive component 6-10 drives the staple gun 6-11 to descend above the board 7 to fix the patch 4-9.

[0103] The working principle of this invention is as follows:

[0104] The board defect detection process is as follows: The board 7 is placed manually at the feed port of the board conveying unit 2. The board defect detection unit 3 detects the defect position on the upper surface of the board 7 and transmits the signal to the control unit. The board 7 continues to move within the stroke range of the head moving mechanism 5. The board positioning component positions the board 7. The control unit calculates the specific position of the defect on the board 7.

[0105] The surface mount material loading process: The loading drive unit 4-1b drives the raw material hopper to rise until the loading detection unit 4-1e detects the surface mount material 4-1i and stops. The dispensing drive unit 4-2b drives the dispensing suction cup assembly to descend and pick up a section of the surface mount material 4-1i, and then rises a certain distance. The feeding linear module 4-3a drives the gripper cylinder 4-3c to move to one end of the picked-up surface mount material 4-1i. The gripper cylinder 4-3c clamps the surface mount material 4-1i, and the feeding linear module 4-2b... -3a transfers the chip material 4-1i to the punching mechanism 4-4 for punching, and then the chip gripping mechanism 4-6 transfers the punched chip 4-9 to the chip gripping station 4-5, waiting for the head mechanism 6 to grip it. When the feeding linear module 4-3a drives the gripper cylinder 4-3c to retreat, the chip material 4-1i is not detected, indicating that the length of the chip material 4-1i is insufficient. The rotary cylinder 4-3b then releases the chip material 4-1i into the waste discharge channel 4-8.

[0106] The board patching process: The machine head mechanism 6 first moves to the patch gripping station 4-5 to grip the patch 4-9, and then moves to the defect position of the board 7. The milling spindle 6-2 mills the defect position on the board 7 to a depth (e.g., 3mm) that matches the patch. Then, the suction drive component 6-4 drives the patch suction cup 6-3 to descend and release the patch 4-9 at the milled position on the board 7. The pressure plate 6-7 then presses the patch 4-9 firmly. After that, the staple gun drive component 6-10 drives the staple gun 6-11 to descend and fix the patch 4-9, thus completing the patching operation on the board 7. After all defects are patched, the board 7 continues to move to the discharge port, where it can be manually removed.

[0107] In summary, this patching and repair equipment can automatically patch defects on sheet metal, improving production efficiency and safety.
