Description

Technical Field

[0001] This invention relates to the field of photovoltaic frame processing technology, specifically to a multi-station integrated processing equipment for photovoltaic frames and its usage method. Background Technology

[0002] A photovoltaic frame is a photovoltaic module used to fix photovoltaic panels and connect them to photovoltaic brackets. It is usually made of aluminum square tubes. The typical features of photovoltaic aluminum frames are that they have 45-degree tilt angles at both ends, corner code stamping for frame-to-frame connection, and through holes for drainage, installation and grounding. The process generally involves first cutting the aluminum material and cutting the bevel, then processing the holes, and finally stamping the corner code. In the current production line process, in order to ensure the precise coordination of multiple stations, robotic arms are often used for clamping and displacement.

[0003] However, since the entire production process of photovoltaic frames involves many steps, if each step is connected by a robot or conveyor, it will result in a large equipment footprint and high equipment costs. Summary of the Invention

The positions of the electric clamp, the feeding rack, and the baffle correspond to each other.

[0007] Preferably, the feeding mechanism further includes a cross-section cutting device, which includes a cross-section cutting machine. The middle part of the cross-section cutting machine is rotatably connected to a fixed seat on the upper wall of the support. The output end of the cross-section cutting machine is located above the electric clamp and the feeding frame. The other end of the cross-section cutting machine is rotatably connected to one end of a support rod. The other end of the support rod is rotatably connected to a crossbar. The two ends of the crossbar are slidably connected inside the two supports, and a spring is provided between the crossbar and the support.

[0008] Preferably, the punching mechanism includes a double-acting cylinder, a pressure frame is fixedly connected to the output end of the double-acting cylinder, an upper pressure plate is fixedly connected to the lower end of the pressure frame, a punching head is provided on the lower wall of the upper pressure plate, a lower partition is provided below the upper pressure plate, the two ends of the upper pressure plate and the lower partition are slidably connected to the limiting frame, the lower wall of the lower partition is fixedly connected to the output end of a single-acting cylinder, and the seat end of the single-acting cylinder is fixedly connected to the inside of the base.

[0009] Preferably, the conveying mechanism includes a fixed frame, the lower part of which is slidably connected to a groove in the upper wall of the base. A lead screw is rotatably connected in the groove in the middle of the base. The threaded end of the lead screw passes through and is threadedly connected to the middle of the fixed frame. The end of the lead screw away from the gantry is fixedly connected to the output end of a stepper motor. A drive plate is fixedly connected to the upper end of the fixed frame. The drive plate is located between the crossbar and the electric clamp. The side of the fixed frame near the gantry is connected to the fixed plate through an electric push rod. The fixed plate is assisted in stamping through stamping holes on its surface and is used for unloading.

[0010] Preferably, the corner code embossing mechanism includes a stamping cylinder and a crossbar. The seat end of the stamping cylinder is fixedly connected to the side walls of both ends of the fixed frame. An embossing male head is fixedly connected to the output end of the stamping cylinder. Both ends of the crossbar are fixedly connected to the lower part of the gantry frame. An embossing female head corresponding to the embossing male head is provided on the side of the crossbar opposite to the stamping cylinder.

[0011] Preferably, a conveyor is provided below the limit frame and the crossbar, and the conveyor is used for material output.

[0012] Preferably, the method of using the multi-station integrated processing equipment for photovoltaic frames includes the following steps:

[0013] Step 1: Use the tube feeding machine to insert the square tube into the feeding rack, and let it pass through the electric clamp in sequence under its limit, and be stopped by the baffle at a fixed length;

[0014] Step 2: When the stepper motor drives the lead screw to reverse, it causes the fixed frame to move away from the gantry frame, which in turn causes the drive plate to push the crossbar to move, which in turn causes the support rod to move. This causes the end of the cross-section cutter connected to the support rod to rotate upward, which in turn causes the output end of the cross-section cutter to move downward to cut the square tube, thus completing the fixed-length feeding of the square tube.

[0015] Step 3: When the stepper motor drives the lead screw to rotate forward, it will move the fixed frame toward the gantry. At the same time, the electric clamp will release the clamp on the square tube, and the drive plate will push the square tube toward the gantry until it is blocked by the limit frame. At this time, the square tube is above the lower partition, and then the square tube will move to the punching position.

[0016] Step 4: The output end of the double-acting cylinder pushes the pressure frame to press down the upper pressure plate, which in turn drives the square tube and the lower partition to move vertically down along the limit frame. When it passes the bevel cutting machine, the two ends of the square tube are beveled by the bevel cutting machine.

[0017] Step 5: The double-acting cylinder continues to push the square tube down until it reaches the predetermined position. At this time, the square tube and the lower partition are both separated from the limiting frame. Then, the electric push rod on the fixed frame pushes the fixed plate to insert into the square tube. The double-acting cylinder pushes the upper pressure plate again, and with the assistance of the punching hole on the fixed plate, the punching head of the upper pressure plate punches a hole in the upper side wall of the square tube. After the punching is completed, the double-acting cylinder drives the upper pressure plate to move up, and then the unloading is completed under the restriction of the fixed plate.

[0018] Step Six: The electric push rod on the fixed frame pushes the fixed plate again until the square tube is blocked by the crossbar. At this time, the output end of the stamping cylinder moves towards the square tube, so that its stamping male head cooperates with the stamping female head of the crossbar to complete the corner code stamping at both ends of the square tube. At this time, the stamping cylinder extends and the electric push rod retracts synchronously, so that the fixed frame is separated from the square tube. Then, the stepper motor drives the lead screw to reverse, which drives the fixed frame to move away from the gantry frame, so that the stamping male head is separated from the square tube. The square tube then falls to the conveyor, thus completing the discharge.

[0019] This invention provides a multi-station integrated processing equipment and method for photovoltaic frames. It has the following beneficial effects:

[0020] This invention utilizes the cooperation between the feeding mechanism, conveying mechanism, punching mechanism, and corner mark imprinting mechanism to enable the conveying mechanism to simultaneously perform pipe length cutting, feeding, conveying, auxiliary punching, and unloading, and the corner mark imprinting mechanism to simultaneously perform corner mark imprinting and unloading. This strengthens the connection between multiple workstations and reduces the use of high-cost devices such as robotic arms, thus achieving the goal of low cost and low footprint of the equipment.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figure 1-9As shown, this embodiment of the invention provides a multi-station integrated processing equipment for photovoltaic frames, including a base 1. A gantry frame 2 and a support 3 are fixedly connected to the upper wall of the base 1. A limit frame 10 is fixedly connected to the lower inner side wall of the gantry frame 2 through side beams 9. An angled cutting machine 17 is fixedly connected to the middle of both side beams 9. The support 3 is perpendicular to the lower opening direction of the gantry frame 2 and one end is fixedly connected to the side wall of the limit frame 10. A punching mechanism is fixedly connected to the upper part of the gantry frame 2. A feeding mechanism is provided on the upper wall of the support 3. A conveying mechanism is also provided on the upper wall of the base 1. The conveying mechanism is located between the two supports 3. The conveying mechanism is used to control the section cutting machine 16 to cut the tube and push the tube to the punching mechanism, and is used for unloading the tube from the punching mechanism. An angle code stamping mechanism is provided on both sides of the conveying mechanism. The angle code stamping mechanism is used to stamp angle codes on both ends of the tube and is used for unloading the tube from the conveying mechanism.

[0034] By coordinating the feeding mechanism, conveying mechanism, punching mechanism, and corner mark stamping mechanism, the conveying mechanism is used simultaneously for feeding, conveying, assisting punching, and unloading of pipes for fixed-length cutting, while the corner mark stamping mechanism is used simultaneously for corner mark stamping and unloading. This strengthens the connection between multiple workstations and reduces the use of high-cost devices such as robotic arms, thus achieving the goal of low cost and low footprint of the equipment.

[0035] The feeding mechanism includes an electric clamp 20, a feeding rack 21, and a baffle 22. The electric clamp 20 is fixedly connected to the upper wall of the support 3, the feeding rack 21 is fixedly connected to the outer wall of one support 3, and the baffle 22 is fixedly connected to the outer wall of another support 3. The positions of the electric clamp 20, the feeding rack 21, and the baffle 22 correspond to each other.

[0036] The square tube is inserted into the feed rack 21 by the tube feeder, and then passes through the electric clamp 20 in sequence under its limit. It is blocked by the baffle 22 at a fixed length, and then the electric clamp 20 clamps and fixes the square tube.

[0037] The feeding mechanism also includes a cross-section cutting device, which includes a cross-section cutter 16. The middle part of the cross-section cutter 16 is rotatably connected to the fixed seat 27 on the upper wall of the support 3. The output end of the cross-section cutter 16 is located above the electric clamp 20 and the feeding rack 21. The other end of the cross-section cutter 16 is rotatably connected to one end of the support rod 19. The other end of the support rod 19 is rotatably connected to a crossbar 18. The two ends of the crossbar 18 are slidably connected inside the two supports 3 respectively, and a spring 26 is provided between the crossbar 18 and the support 3.

[0038] When the stepper motor 25 drives the lead screw 24 to reverse, it causes the fixed frame 6 to move away from the gantry frame 2, which in turn causes the drive plate 7 to push the crossbar 18 to move, thereby driving the support rod 19 to move. This causes the end of the cross-section cutter 16 connected to the support rod 19 to rotate upward, thereby causing the output end of the cross-section cutter 16 to move downward to cut the square tube, thus completing the fixed-length feeding of the square tube.

[0039] At the same time, when the drive plate 7 is moved away, the crossbar 18 is reset under the action of the spring 26, and the output end of the section cutting machine 16 moves up to restore its original position, which facilitates the subsequent feeding of square tubes.

[0040] The punching mechanism includes a double-acting cylinder 4, with a pressure frame 5 fixedly connected to the output end of the double-acting cylinder 4. An upper pressure plate 11 is fixedly connected to the lower end of the pressure frame 5. A punching head is provided on the lower wall of the upper pressure plate 11. A lower partition plate 12 is provided below the upper pressure plate 11. The two ends of the upper pressure plate 11 and the lower partition plate 12 are slidably connected to the limit frame 10, respectively. The lower wall of the lower partition plate 12 is fixedly connected to the output end of a single-acting cylinder 13. The seat end of the single-acting cylinder 13 is fixedly connected inside the base 1.

[0041] The output end of the double-acting cylinder 4 pushes the pressure frame 5 to press down the upper pressure plate 11, thereby driving the square tube and the lower partition 12 to move vertically downward along the limiting frame 10. The single-acting cylinder 13 is used to restore the position of the lower partition 12.

[0042] The conveying mechanism includes a fixed frame 6. The lower part of the fixed frame 6 is slidably connected to the inside of the slide groove 23 on the upper wall of the base 1. A lead screw 24 is rotatably connected in the middle of the slide groove 23 of the base 1. The threaded end of the lead screw 24 passes through and is threadedly connected to the middle of the fixed frame 6. The end of the lead screw 24 away from the gantry 2 is fixedly connected to the output end of the stepper motor 25. A drive plate 7 is fixedly connected to the upper end of the fixed frame 6. The drive plate 7 is located between the crossbar 18 and the electric clamp 20. The side of the fixed frame 6 closest to the gantry 2 is connected to the fixed plate 8 through an electric push rod. The fixed plate 8 is used to assist in stamping and unloading.

[0043] When the stepper motor 25 drives the lead screw 24 to rotate forward, the fixed frame 6 moves toward the gantry 2. At the same time, the electric clamp 20 releases the clamp on the square tube, and the drive plate 7 pushes the square tube toward the gantry 2 until it is blocked by the limit frame 10. At this time, the square tube is located above the lower partition 12, which moves the square tube to the punching position.

[0044] Meanwhile, the fixed frame 6 in the conveying mechanism can also be moved by linear motors, electric push rods, cylinders and other equipment to achieve the same effect.

[0045] The corner code embossing mechanism includes a stamping cylinder 28 and a crossbar 14. The base of the stamping cylinder 28 is fixedly connected to the side walls of both ends of the fixed frame 6. The output end of the stamping cylinder 28 is fixedly connected to an embossing male head 29. The two ends of the crossbar 14 are fixedly connected to the lower part of the gantry frame 2. An embossing female head 30 corresponding to the embossing male head 29 is provided on the side of the crossbar 14 opposite to the stamping cylinder 28.

[0046] The output end of the stamping cylinder 28 moves toward the square tube, so that its stamping male head 29 engages with the stamping female head 30 of the crossbar 14 to complete the corner code stamping at both ends of the square tube. At the same time, the stamping cylinder 28 extends and the electric push rod retracts synchronously, so that the fixed frame 6 is separated from the square tube. Then, the stepper motor 25 drives the lead screw 24 to reverse, which drives the fixed frame 6 to move away from the gantry 2, so that the stamping male head 29 is separated from the square tube.

[0047] A conveyor 15 is installed below the limit frame 10 and the crossbar 14. The conveyor 15 is used for material output.

[0048] The square tube falls onto conveyor 15, thus completing the discharge process.

[0049] Example 2:

[0050] Based on the above embodiments, this embodiment provides a method for using a multi-station integrated processing equipment for photovoltaic frames, including the following steps:

[0051] Step 1: Use the tube feeder to insert the square tube into the feed rack 21, and under its limit, it will pass through the electric clamp 20 in sequence, and be blocked by the baffle 22 at a fixed length.

[0052] Step 2: Stepper motor 25 drives lead screw 24 to reverse, which drives fixed frame 6 to move away from gantry frame 2, causing drive plate 7 to push crossbar 18 to move, which in turn drives support rod 19 to move, causing the end of cross section cutter 16 connected to support rod 19 to rotate upward, which in turn causes the output end of cross section cutter 16 to move downward to cut square tube, thus completing the fixed length feeding of square tube.

[0053] Step 3: Stepper motor 25 drives lead screw 24 to rotate forward, which drives fixed frame 6 to move toward gantry frame 2. At the same time, electric clamp 20 releases clamp on square tube, and drive plate 7 pushes square tube toward gantry frame 2 until it is blocked by limit frame 10. At this time, square tube is above lower partition plate 12, which moves square tube to the punching position.

[0054] Step 4: The output end of the double-acting cylinder 4 pushes the pressure frame 5 to press down the upper pressure plate 11, thereby driving the square tube and the lower partition 12 to move vertically down along the limit frame 10. When passing the bevel cutting machine 17, the two ends of the square tube are beveled by the bevel cutting machine 17.

[0055] Step 5: The double-acting cylinder 4 continues to push the square tube downward until it reaches the predetermined position. At this time, the square tube and the lower partition 12 are both separated from the limiting frame 10. Then, the electric push rod on the fixed frame 6 pushes the fixed plate 8 to insert into the square tube. The double-acting cylinder 4 pushes the upper pressure plate 11 again, and with the assistance of the punching hole on the fixed plate 8, the punching head of the upper pressure plate 11 punches the upper side wall of the square tube. After the punching is completed, the double-acting cylinder 4 drives the upper pressure plate 11 to move upward, and then the unloading is completed under the restriction of the fixed plate 8.

[0056] Step 6: The electric push rod on the fixed frame 6 pushes the fixed plate 8 again until the square tube is blocked by the crossbar 14. At this time, the output end of the stamping cylinder 28 moves towards the square tube, so that its stamping male head 29 cooperates with the stamping female head 30 of the crossbar 14 to complete the corner code stamping at both ends of the square tube. At this time, the stamping cylinder 28 extends and the electric push rod retracts synchronously, so that the fixed frame 6 is separated from the square tube. Then, the stepper motor 25 drives the lead screw 24 to reverse, which drives the fixed frame 6 to move away from the gantry 2, so that the stamping male head 29 is separated from the square tube. The square tube then falls to the conveyor 15, thus completing the discharge.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

At the same time, the electric clamp (20) releases the clamp on the square tube, and the drive plate (7) pushes the square tube toward the gantry (2) until it is blocked by the limit frame (10). At this time, the square tube is above the lower partition (12), which moves the square tube to the punching position.
