Description

Technical Field

[0001] This utility model relates to the technical field of solar photovoltaic module processing equipment, specifically to a novel solar photovoltaic frame drilling device. Background Technology

[0002] As the core structural component of photovoltaic modules, the solar photovoltaic frame is used to fix and seal the solar cell modules. In order to provide better wind resistance and support strength, crossbeams need to be added to the frame. This involves drilling holes in the photovoltaic frame and assembling it with crossbeams. The drilling accuracy is particularly critical.

[0003] In existing technologies, drilling holes in photovoltaic frames is typically done using a standard bench drill or vertical drill press with simple fixtures. During operation, the worker first places the photovoltaic frame on the workbench, initially fixes it using manual or pneumatic fixtures, and then drills holes from top to bottom or horizontally using a drill bit.

[0004] However, the above-mentioned existing technologies still have the following drawbacks: First, the photovoltaic frame is prone to displacement or vibration during the drilling process, which affects the accuracy of the hole position and the quality of the hole. Second, the aluminum shavings generated when drilling from top to bottom or in a horizontal direction will scratch the surface of the photovoltaic frame profile, and the aluminum shavings are difficult to clean.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0006] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a new type of solar photovoltaic frame drilling equipment. Through bottom-up drilling method, clamping and limiting mechanism and waste collection design, it solves the problems of low drilling accuracy, easy scratching of profile surface and difficulty in cleaning aluminum shavings.

[0007] Technical Solution: This utility model provides a novel solar photovoltaic frame drilling device, including a frame, a worktable on the top of the frame, a rectangular through hole in the middle of the upper side of the worktable, the photovoltaic frame being placed on the worktable and above the through hole; a set of pressing cylinders, the pressing cylinders being arranged on the upper side of the worktable along one long side of the rectangular through hole, for pressing and limiting the photovoltaic frame before drilling; and a drilling assembly, the drilling assembly being installed on the lower side of the worktable, for drilling the photovoltaic frame placed on the worktable from bottom to top through the through hole. The frame-supported workbench can stably place the photovoltaic frame, and the rectangular perforation in the middle of the upper part of the workbench can accurately provide an "upward" operating channel for the drilling component, ensuring that the drilling position of the frame is precisely aligned with the perforation. A set of downward pressing cylinders arranged along one long side of the rectangular perforation can evenly press the long side of the photovoltaic frame before drilling, preventing the frame from shifting due to vibration and force during the drilling process, and achieving stable positioning of the frame. The drilling component installed on the lower side of the workbench can perform drilling operations from the bottom to the top of the frame through the perforation, changing the traditional "upward" drilling direction. Waste chips automatically fall off under the action of gravity, which facilitates chip removal.

[0008] Furthermore, this application discloses a novel solar photovoltaic frame drilling device. The drilling assembly includes a support plate, which is suspended below the workbench via a connecting plate. The support plate has a slide rail, which is parallel to the workbench. A set of sliders is mounted on the slide rail, and a cylinder is mounted on each slider. An electric drill is mounted on the output end of the cylinder, and a stepped drill bit is provided at the front end of the drill. During operation, the cylinder drives the electric drill to move vertically upwards, and the stepped drill bit passes through a perforation to drill a hole in the photovoltaic frame that is pressed and limited on the workbench. The support plate, suspended below the workbench via the connecting plate, provides a stable mounting foundation for the slide rail, sliders, cylinder, and electric drill. Simultaneously, the suspension structure ensures that the entire drilling assembly remains parallel to the workbench, preventing drilling direction deviation due to component tilt, thus laying a structural foundation for subsequent precise drilling. The slide rail on the support plate is parallel to the workbench, and the slider can slide along the slide rail, driving the cylinder and electric drill to move horizontally synchronously. This design can flexibly adjust the horizontal coordinate of the electric drill according to the different drilling positions required by the photovoltaic frame, and can adapt to various hole layouts without frequent disassembly or adjustment of the frame position.

[0009] Furthermore, in this application, a novel solar photovoltaic frame drilling device includes a limiting slot block on the worktable. The limiting slot block is located on the outer edge of the worktable and along the extension direction of the rectangular perforation. The limiting slot block has a groove that matches the photovoltaic frame. Before drilling, one end of the photovoltaic frame is inserted into the groove, which limits the circumferential position of the photovoltaic frame. The limiting slot block is positioned along the extension direction of the rectangular perforation, with the center of its groove precisely corresponding to the center of the perforation. After one end of the frame is inserted into the groove, no repeated manual adjustment is required; the positioning guide of the groove automatically aligns the area of ​​the frame to be drilled with the perforation.

[0010] Furthermore, in this application, a novel solar photovoltaic frame drilling device is provided with a suction cup at the output end of the pressing cylinder. The suction cup is made of rubber. When the pressing cylinder performs a pressing operation, the suction cup presses the photovoltaic frame tightly onto the worktable. When the drilling is finished, the suction cup lifts the drilled photovoltaic frame together with the resetting of the pressing cylinder. The suction cup is made of rubber, which has good elasticity and a high coefficient of friction. When the pressing cylinder drives the suction cup to press down, the rubber will slightly deform according to the contour of the frame surface, achieving a tight fit with the photovoltaic frame. Compared with the rigid contact of the metal pressure block, the rubber material can buffer the instantaneous impact force when the cylinder presses down. When the pressing cylinder quickly drives the suction cup to contact the frame, the rubber will absorb part of the impact force through deformation, preventing the frame from developing indentations, dents, or deformations due to excessive local pressure.

[0011] Furthermore, this application discloses a novel solar photovoltaic frame drilling device where the spacing between the sliders is adjustable, and several limiting blocks are also mounted on the slide rail. These limiting blocks restrict the movement of the sliders along the slide rail after the spacing between them is adjusted. The sliders can slide freely along the slide rail, allowing adjustment of the spacing between adjacent sliders (and the cylinders and electric drills on the sliders). It can directly adjust the relative distance between electric drills by sliding the sliders according to different multi-hole processing requirements of the photovoltaic frame (such as 2 holes, 3 holes, and different hole spacing specifications), without disassembling or replacing the electric drill mounting components. It adapts to various hole spacing layouts. The limiting blocks on the slide rail can be locked onto both sides of the sliders after the slider spacing is adjusted, physically restricting the movement of the sliders along the slide rail. This function can fix the adjusted slider position, preventing slider displacement due to vibration or force during electric drill operation, and ensuring that multiple electric drills always maintain the preset hole spacing accuracy.

[0012] Furthermore, in this application, a novel solar photovoltaic frame drilling device includes a shelf at the bottom of the frame, and a waste bin on the shelf. The opening of the waste bin is located directly below the perforation. Aluminum shavings generated during drilling will naturally fall from the perforation into the waste bin below under the influence of gravity.

[0013] Furthermore, in this application, a novel solar photovoltaic frame drilling device is provided with rollers and an adjustment seat at the lower end of the frame.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The novel solar photovoltaic frame drilling equipment described in this utility model adopts a bottom-up drilling method, which allows the aluminum shavings generated during drilling to fall naturally downwards under the action of gravity, effectively avoiding the problem of aluminum shavings accumulating and scratching the surface of the photovoltaic frame profile. At the same time, combined with the waste shavings box set directly below the perforation, the automatic collection and cleaning of aluminum shavings is realized, which greatly improves the working environment and increases production efficiency.

[0015] 2. The novel solar photovoltaic frame drilling device of this utility model achieves rapid and accurate positioning and flexible and gentle clamping of the photovoltaic frame before drilling by setting a rubber suction cup clamping mechanism driven by a downward pressure cylinder and a limiting slot block. After drilling, the frame can be picked up for easy handling. This design effectively prevents the frame from displacement and vibration during the drilling process, significantly improves the processing accuracy and hole quality, and protects the frame surface from pressure damage.

[0016] 3. The novel solar photovoltaic frame drilling equipment described in this utility model designs the drilling components as a structure that can move on a slide rail and has adjustable spacing, and fixes them with limiting blocks. This allows a single device to flexibly and quickly adapt to the drilling needs of various hole spacings on photovoltaic frames of different specifications, greatly enhancing the versatility and processing flexibility of the equipment, and reducing the frequency and time of changing tooling fixtures.

Detailed Implementation

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 like Figures 1 to 6 This embodiment illustrates a novel solar photovoltaic frame drilling device. Taking the processing of a certain type of rectangular solar photovoltaic frame (which requires processing three equally spaced mounting holes on the long side) as an example, this embodiment details the assembly and operation process of the novel solar photovoltaic frame drilling device.

[0021] I. Equipment Assembly and Debugging Frame and foundation construction Place the frame 1 on a flat workshop floor, and push the equipment to the designated processing station using the rollers 11 at the bottom of the frame 1. Then, screw the adjusting seat 12 so that the bottom of the adjusting seat 12 is in close contact with the ground, fully supporting the frame 1 and preventing the equipment from shaking during operation. Place the waste shavings box 6 on the shelf 5 below the frame 1, and adjust the position of the waste shavings box 6 to ensure that its opening is precisely aligned with the bottom of the rectangular perforation 21 on the workbench 2, so as to collect the aluminum shavings generated during drilling.

[0022] Workbench and positioning mechanism layout The workbench 2 is fixedly installed above the frame 1. A rectangular through hole 21 matching the area to be drilled on the photovoltaic frame is machined in the middle of the upper side of the workbench 2. A limiting slot block 22 is fixed on the outer edge of the workbench 2 along the extension direction of the rectangular through hole 21 to ensure that the contour of the slot 221 of the limiting slot block 22 is completely matched with the end shape of the photovoltaic frame to be processed, and the center line of the slot 221 is on the same straight line as the center line of the through hole 21, so as to realize the pre-positioning guidance of the frame.

[0023] Downward cylinder installation Along one long side of the rectangular perforation 21, two pressing cylinders 3 are installed on the upper side of the workbench 2. The spacing between the two pressing cylinders 3 is set according to the length of the long side of the photovoltaic frame (to ensure that the middle and near-end positions of the frame can be pressed evenly). Rubber suction cups 31 are installed at the output end of each pressing cylinder 3. The flatness of the surface of the suction cups 31 is checked to ensure that they can form a stable fit when in contact with the surface of the photovoltaic frame.

[0024] Drilling component debugging The support plate 41 is hoisted onto the underside of the workbench 2 via the connecting plate 42, ensuring that the support plate 41 is parallel to the workbench 2. A slide rail 43 is fixed on the support plate 41, with the length direction of the slide rail 43 aligned with the long side direction of the through hole 21 on the workbench 2. Three sliders 44 are installed on the slide rail 43. The spacing of the three sliders 44 is adjusted by sliding them according to the design spacing of the three mounting holes of the photovoltaic frame. After the spacing is adjusted to the correct position, limit blocks 48 are respectively installed on the slide rail 43 on both sides of each slider 44. The locking structure between the limiting block 48 and the slide rail 43 restricts the movement of the slider 44 along the slide rail 43, ensuring that the positions of the three sliders 44 are fixed. A cylinder 45 is installed on each slider 44, with the output end of the cylinder 45 pointing vertically upward. An electric drill 46 is fixed at the end of the output end, and the axis of the electric drill 46 is perpendicular to the worktable 2. Finally, a suitable stepped drill bit 47 is installed at the front end of each electric drill 46, and the sharpness of the cutting edge of the stepped drill bit 47 is checked to ensure that the aluminum profile can be cut smoothly when drilling.

[0025] II. Photovoltaic frame drilling operation procedure Workpiece positioning and clamping The operator holds the photovoltaic frame to be processed and places it on the workbench 2 with its long side facing up. At the same time, one end of the photovoltaic frame is slowly pushed into the groove 221 of the limiting slot block 22 until the end of the frame is completely in contact with the bottom of the groove 221. At this time, the area of ​​the photovoltaic frame to be drilled just covers the rectangular perforation 21. The control switch of the two pressing cylinders 3 is activated. The piston rod of the pressing cylinder 3 extends downward, driving the suction cup 31 to move down synchronously until the suction cup 31 is in close contact with the upper surface of the photovoltaic frame. As the pressing cylinder 3 continues to output pressure, the suction cup 31 undergoes slight elastic deformation, firmly pressing the photovoltaic frame onto the workbench 2, realizing the stable positioning of the frame.

[0026] Drilling operation from bottom to top When the control power of the drilling assembly 4 is turned on, the three electric drills 46 start simultaneously, driving the stepped drill bit 47 to rotate at high speed. Then, the piston rods of the three cylinders 45 extend upward in sync, driving the electric drills 46 to move upward in the vertical direction. Under the thrust of the cylinders 45, the stepped drill bit 47 gradually approaches and passes through the perforation 21 of the worktable 2, and begins cutting after contacting the lower surface of the photovoltaic frame. Due to the special structure of the stepped drill bit 47, a small-diameter guide hole is first formed during the drilling process, and then expanded to the target hole diameter, effectively avoiding drilling deviation. The aluminum chips generated during drilling fall from the perforation 21 into the waste chip box 6 below under the action of gravity, and will not accumulate on the surface of the photovoltaic frame or on the worktable 2.

[0027] Workpiece resetting and material handling Once the stepped drill bit 47 has completely penetrated the photovoltaic frame and reached the preset drilling depth, the piston rod of the cylinder 45 retracts in the opposite direction, causing the electric drill 46 and the stepped drill bit 47 to synchronously return to their downward position until the stepped drill bit 47 completely exits the perforation 21. After the electric drill 46 stops rotating, the piston rods of the two downward cylinders 3 return to their upward position. At this time, the suction cup 31 remains attached to the surface of the photovoltaic frame due to the adsorption force of the rubber material. Synchronously with the return of the downward cylinders 3, the photovoltaic frame is lifted upward, causing the lower surface of the photovoltaic frame to detach from the upper surface of the worktable 2. The operator can then directly hold the un-drilled end of the photovoltaic frame and gently pull it outward to remove the processed photovoltaic frame from the equipment, completing a single drilling operation.

[0028] In this embodiment, two downward pressing cylinders 3 achieve uniform clamping of the photovoltaic frame, and three electric drills 46, together with adjustable spacing sliders 44 and side-mounted limiting blocks 48, accurately complete multi-hole processing. At the same time, through the bottom-up drilling direction and the cooperation of the waste shavings box 6, the problem of aluminum shavings scratching the frame and cleaning difficulties in traditional equipment is completely solved. Moreover, the positioning accuracy is high and the degree of automation is high throughout the process, which meets the needs of batch processing of photovoltaic frames.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
