Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module drilling, and particularly relates to an automatic drilling structure for metal components of photovoltaic panels. Background Technology

[0002] Photovoltaic tube support columns are one of the core components of the metal support assembly for photovoltaic panels. They are usually installed on the ground or roof and their main function is to support the photovoltaic panel assembly on the entire support structure.

[0003] In photovoltaic column construction, the traditional drilling process requires manual operation to complete positioning and drilling operations step by step. During construction, the operator first attaches the U-shaped hook provided with the equipment to the circular tube of the photovoltaic foundation pile. The anti-slip texture on the hook surface enhances the friction between the hook and the tube, thus achieving initial fixation of the equipment. Then, by holding the handle on the mounting plate, the angle of the pistol drill is adjusted so that the drill bit is accurately aligned with the preset drilling position. Finally, the gear handle is turned, and the meshing transmission between the gear and the stepper gear drives the slider and the pistol drill fixed on the slider to move back and forth in a straight line, providing stable propulsion force for the pistol drill, and finally completing the drilling process of the circular tube column.

[0004] However, traditional drilling tools have significant technical shortcomings in practical applications, making it difficult to meet the demands of high-precision construction. On one hand, to ensure the drill bit can completely penetrate the diameter of the cylindrical column, the drill bit and drill rod are designed to be long and thin, making them prone to vibration when in contact with the smooth surface of the cylindrical column. Simultaneously, when operators hold the equipment, hand vibrations are further transmitted to the drilling machine, resulting in a double vibration that causes drilling position deviation and irregular hole diameter, severely affecting drilling quality. On the other hand, the equipment's control of the vertical hole spacing on the cylindrical column relies entirely on manual experience, lacking a precise automatic positioning mechanism. When construction requires strict control of the hole spacing to ensure accurate installation of subsequent components, external measuring tools such as tape measures and levels, as well as auxiliary support equipment, must be used in conjunction with the operation. This not only increases the complexity of the construction process but also introduces human measurement errors, significantly limiting its usability. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automated drilling structure for metal components of photovoltaic panels, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides an automatic drilling structure for photovoltaic panel metal components, including a rectangular mounting frame. Each of the two short sides of the mounting frame is equipped with a clamping locking mechanism and a drilling mechanism, and a positioning support mechanism is jointly provided between the clamping locking mechanism and the two long sides of the mounting frame. The drilling mechanism includes a sliding component disposed on the upper side of the short side of the mounting frame, and an electric drill is mounted on the sliding component. The positioning support mechanism includes a bracket disposed on the clamping locking mechanism, the bracket being connected to the two long sides of the mounting frame, and a spring telescopic pin is provided on the bracket via a height adjustment component. The clamping locking mechanism on the two short sides cooperates with the mounting frame to simultaneously clamp both sides of the photovoltaic cylinder; simultaneously, two electric drills jointly push the photovoltaic cylinder forward through their respective sliding components. The drill bits of the two electric drills form two additional force-balanced support points on the surface of the column. The spring telescopic pin cooperates with the clamping locking mechanism, and is inserted into the pre-drilled hole on the surface of the photovoltaic cylinder to position the electric drill.

[0007] According to an advantageous embodiment, the mounting frame is provided with an opening, a long side of the mounting frame is rotatably disposed in the opening via a pivot, and a connecting bolt is threaded on a short side of the mounting frame, with the end of the rotatable long side of the mounting frame away from the pivot being threadedly connected to the connecting bolt.

[0008] According to an advantageous embodiment, the clamp locking mechanism includes a locking screw threaded through an ear seat on the lower side of the short frame of the mounting frame. The ends of the two locking screws that are close to each other are rotatably connected to an arc-shaped locking guard plate. The sides of the two locking guard plates that are opposite to each other are fixedly provided with two guide rods. The lower side of the short frame of the mounting frame is movably connected to the corresponding guide rods through an ear seat.

[0009] According to an advantageous embodiment, two symmetrical strip holes are provided on the inner sidewalls of the two long sidewalls of the mounting frame that are close to each other. The bracket includes two horizontal plates that are slidably connected to the corresponding strip holes. An L-shaped plate with equal side length is provided on the side of the two horizontal plates that are close to each other. The bending part of the L-shaped plate is rotatably connected to the smooth section of the locking screw through a bearing.

[0010] According to an advantageous embodiment, the sliding assembly includes a sliding plate slidably disposed on the upper side of the short frame of the mounting frame, an electric drill fixedly disposed on the sliding plate, an electric push rod fixedly disposed on the outer side of the short frame of the mounting frame, and an ear seat three fixedly disposed on the lower side of the sliding plate and at a position away from the fixed end of the electric push rod, the telescopic end of the electric push rod movably passing through the short frame of the mounting frame and fixedly connected to the corresponding ear seat three.

[0011] According to an advantageous embodiment, trapezoidal plates extending outward and symmetrically arranged on the outer sides of both short frames of the mounting frame are fixedly provided. T-shaped slides are opened on the upper side of the trapezoidal plates and the upper side of the corresponding short frames of the mounting frame. Two T-shaped guide plates symmetrically arranged on the lower side of the slide plate are fixedly provided. The guide plates are slidably arranged in the corresponding slides.

[0012] According to an advantageous embodiment, the height adjustment assembly includes a column fixedly connected to the upper side of the bend of the L-shaped plate, an adjustment screw rotatably disposed on the column, an adjustment block threaded on the adjustment screw, the adjustment block being slidably connected to the column, and a spring telescopic pin disposed on the adjustment block.

[0013] According to an advantageous embodiment, the spring telescopic pin includes a fixed sleeve fixedly connected to the adjusting block, a spring fixedly disposed inside the fixed sleeve, a positioning pin fixedly connected to the movable end of the spring, and the positioning pin slidably connected to the fixed sleeve.

[0014] Compared with existing technologies, the automatic drilling structure for photovoltaic panel metal modules provided in this invention has the following advantages: 1. In this invention, an openable and rectangular mounting frame is used, which, when closed, forms a rigid whole surrounding the column. The arc-shaped guard plate is synchronously driven by locking screws on both sides, achieving balanced and secure clamping of the photovoltaic column, completely eliminating the reliance on friction in traditional methods and fundamentally preventing equipment slippage and shaking. During the jacking operation, the drill bit of the double-sided electric drill forms two additional and mutually balanced action points with the column contact point, further enhancing the overall rigidity and stability.

[0015] 2. In this invention, the dual-electric drill simultaneously drills holes from both sides of the photovoltaic cylinder to form through holes, eliminating the need for the drill rod to completely penetrate the cylinder. The short drill rod shortens the driving force transmission distance and has greater rigidity, thus avoiding the vibration problem caused by a long and thin drill rod from the source.

[0016] 3. In this invention, the spring telescopic pin in the positioning support mechanism can be pre-adjusted in height according to the preset hole spacing. After drilling the first set of holes, simply insert the spring telescopic pin into the drilled holes to automatically position the second set of holes. This eliminates the need for external tools such as tape measures and levels, completely eliminating manual measurement errors and ensuring that the distance between the upper and lower holes of the photovoltaic cylinder remains consistent with the preset distance.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0025] Please refer to the following: Figure 1 An automatic drilling structure for photovoltaic panel metal components includes a rectangular mounting frame 1. The mounting frame 1 consists of two long side frames and two short side frames. The two short side frames and one long side frame are fixedly connected end to end to form a U-shaped frame. The other long side frame is rotatably set in the opening of the U-shaped frame via a pivot. A connecting bolt 5 is threaded on one of the short side frames of the mounting frame 1. The end of the rotatable long side frame of the mounting frame 1 away from the pivot is threadedly connected to the connecting bolt 5. A clamping locking mechanism 2 and a drilling mechanism 3 are provided on both short side frames of the mounting frame 1. A positioning support mechanism 4 is provided between the clamping locking mechanism 2 and the two long side frames of the mounting frame 1.

[0026] In practice, the workers move the mounting frame 1 to the vicinity of the photovoltaic cylinder to be drilled, then open the rotatable long frame of the mounting frame 1, place the opened mounting frame 1 onto the photovoltaic cylinder, close the long frame, and lock it with the connecting bolts 5. Afterward, the mounting frame 1 is raised to the predetermined height, and the entire assembly is fixed to the photovoltaic cylinder by the clamping locking mechanism 2. Then, the drilling mechanism 3 automatically drills holes in the photovoltaic cylinder.

[0027] See Figures 1-5The clamping locking mechanism 2 includes a locking screw 21 that is threaded through an ear seat and installed on the lower side of the short frame of the mounting frame 1. The ends of the two locking screws 21 that are close to each other are rotatably connected to an arc-shaped locking guard plate 22. The sides of the two locking guard plates 22 that are opposite to each other are fixedly provided with two guide rods 23. The lower side of the short frame of the mounting frame 1 is movably inserted into the corresponding guide rod 23 through an ear seat.

[0028] In practice, a rectangular mounting frame 1 is fitted onto the surface of the photovoltaic cylinder. Then, the operator manually rotates the locking screw 21 on the left side to extend the locking guard plate 22 by a certain length, so that the locking guard plate 22 abuts against the surface of the photovoltaic cylinder. In this state, the operator then rotates the locking screw 21 on the right side until the locking guard plate 22 on the locking screw 21 abuts against the surface of the photovoltaic cylinder. Then, the operator adjusts the abutment force of the two locking guard plates 22 on the left and right sides against the photovoltaic cylinder to be the same, so that the whole thing can be fixed on the photovoltaic cylinder and will not slide down automatically.

[0029] It should be noted that a scale line (each division corresponds to a displacement of 0.5mm) is set on the body of the locking screw 21, and a pointer is fixed on the ear seat. The movement distance of the screws on both sides is intuitively controlled by aligning the pointer with the scale. The distance that the locking screw 21 moves relative to its respective ear seat ensures that the two locking guard plates 22 have the same contact force with the photovoltaic cylinder.

[0030] See Figures 1-5 The drilling mechanism 3 includes a sliding component 31 disposed on the upper side of the short frame of the mounting frame 1, and an electric drill 32 disposed on the sliding component 31. The sliding component 31 includes a slide plate 311 slidably disposed on the upper side of the short frame of the mounting frame 1, and the electric drill 32 is fixedly disposed on the slide plate 311. An electric push rod 312 is also fixedly disposed on the outer side of the short frame of the mounting frame 1. A lug three is fixedly disposed on the lower side of the slide plate 311 and at a position away from the fixed end of the electric push rod 312. The telescopic end of the electric push rod 312 movably passes through the short frame of the mounting frame 1 and is fixedly connected to the corresponding lug three.

[0031] In actual operation, the electric actuator 312 drives the sliding plate 311 to move, which in turn drives the electric drill 32 to approach the surface of the photovoltaic cylinder to drill a hole. The two electric drills 32 advance simultaneously. Since the electric drill 32 only needs to drill a hole on one side of the photovoltaic cylinder, the electric drill 32 can use a short drill rod to shorten the driving force transmission distance in the electric drill 32. This makes the tip of the short drill rod more stable when drilling the surface of the photovoltaic cylinder. The two electric drills 32 advance together from different directions, and the jacking force they generate is balanced inside the photovoltaic cylinder, which further enhances the overall rigidity and stability of the equipment at the moment of drilling.

[0032] It should be noted that although this solution adds an electric drill 32 and a set of sliding components 31 compared to the traditional photovoltaic cylindrical drilling machine, which increases the overall weight, it can be moved with the assistance of an external mobile cart or other mobile tools. Although the addition of an electric drill 32 and sliding components 31 will increase the equipment cost, in batch construction scenarios, the improved drilling accuracy and efficiency can significantly reduce the rework rate, resulting in better overall economic performance.

[0033] See Figure 2 and Figure 4 The mounting frame 1 has two outwardly extending and symmetrical trapezoidal plates 313 fixedly installed on the outer sides of its two short frames. The upper side of each trapezoidal plate 313, together with the upper side of the corresponding short frame of the mounting frame 1, has a T-shaped slide rail. The lower side of the sliding plate 311 has two symmetrical and T-shaped guide plates 314 fixedly installed, which slide within their respective slide rails. The sliding plate 311 moves the electric drill 32 by sliding along the lower guide plates 314 on the underside of the mounting frame 1.

[0034] See Figure 1 and Figure 3 To ensure accurate spacing between the upper and lower openings of the photovoltaic cylinder, the positioning support mechanism 4 includes a bracket 41 mounted on the locking screw 21. The bracket 41 is slidably connected to one long side of the mounting frame 1, and is movably connected to the other long side of the mounting frame. A spring telescopic pin 43 is provided on the bracket 41 via a height adjustment component 42.

[0035] See Figure 1 , Figure 3 and Figure 6 On the inner sidewalls of the two long sidewalls of the mounting frame 1, which are close to each other, there are two symmetrical strip holes 6. The bracket 41 includes two horizontal plates 411, which are slidably connected to the corresponding strip holes 6. On the side of the two horizontal plates 411 that are close to each other, there is a common L-shaped plate 412 with equal side length. It should be noted that the L-shaped plate 412 is integrally formed with the horizontal plate 411. The bend of the L-shaped plate 412 is rotatably connected to the smooth section of the locking screw 21 through a bearing. The locking screw 21 is slidably connected to the two long sidewalls of the mounting frame 1 through the bracket 41. The bracket 41 provides vertical support for the locking screw 21 to prevent it from bending and deforming due to force, while the axial force of clamping the photovoltaic cylinder is still transmitted by the locking screw 21 itself.

[0036] In practice, the distance between the spring telescopic pin 43 and the drill bit 32 of the electric drill is pre-adjusted according to the distance between the upper and lower holes of the photovoltaic column. This pre-adjustment determines the spacing between the upper and lower holes of the photovoltaic column. After pre-adjustment, once a set of through holes are drilled on the photovoltaic column, rotating the locking screw 21 in the reverse direction releases the locking plate 22. Then, the entire column is raised so that the telescopic end of the spring telescopic pin 43 aligns with the previously drilled holes. At this point, rotating the locking screw 21 in the forward direction locks the entire column again, allowing the spring telescopic pin 43 to be inserted into the previously drilled holes. Furthermore, when positioning the second set of holes, the spring telescopic pin 43 also prevents the entire column from moving downwards due to drilling vibrations, achieving precise positioning and ensuring that the spacing between the upper and lower holes of the photovoltaic column matches the preset spacing, thus ensuring the smooth installation of other photovoltaic components.

[0037] See Figure 1 , Figure 3 and Figure 6 To meet the varying spacing requirements of the vertical through holes in the photovoltaic cylinder, the height adjustment assembly 42 includes a column 421 fixedly connected to the upper side of the bent portion of the L-shaped plate 412. An adjusting screw 422 is rotatably mounted on the column 421, and an adjusting block 423 is threaded onto the adjusting screw 422. The adjusting block 423 is slidably connected to the column 421, and a spring telescopic pin 43 is mounted on the adjusting block 423. Operators can adjust the position of the spring telescopic pin 43 by simply rotating the adjusting screw 422 to move the adjusting block 423 up and down.

[0038] See Figure 3 and Figure 6 The spring telescopic pin 43 includes a fixed sleeve fixedly connected to the adjusting block 423. A spring (not shown in the figure) is fixedly installed inside the fixed sleeve. A positioning pin is fixedly connected to the movable end of the spring, and the positioning pin is slidably connected to the fixed sleeve. The spring telescopic pin 43 can move closer to the photovoltaic cylinder along with the locking guard plate 22. When there are no holes on the surface of the photovoltaic cylinder at the beginning, the positioning pin moves closer to the photovoltaic cylinder along with the locking guard plate 22 and slides relative to the fixed sleeve after contacting the photovoltaic cylinder, compressing the spring and preventing the positioning pin from interfering with the movement of the photovoltaic cylinder.

[0039] In this design, an openable rectangular mounting frame 1 is used. When closed, it forms a rigid structure surrounding the photovoltaic cylinder, providing a stable base platform for the entire drilling operation and fundamentally avoiding the instability of handheld equipment. The photovoltaic cylinder is simultaneously clamped from both sides by the clamping locking mechanism 2 (locking screw 21 and locking guard plate 22) on the two short frames, providing uniform and strong friction to ensure that the equipment will not shift or slip during drilling. Compared with traditional single-point hooks relying on anti-slip textures, the fixing effect is significantly improved. Two electric drills 32 advance from different directions, and their drill bits form two additional force-bearing support points when they contact the surface of the column 421, further enhancing the overall stability of the equipment during drilling.

[0040] The dual-electric drill rig 32 drills holes simultaneously from both sides of the photovoltaic cylinder to form through holes, eliminating the need for the drill rod to completely penetrate the column 421. The short drill rod shortens the driving force transmission distance and has greater rigidity, thus avoiding vibration problems caused by long and thin drill rods from the outset.

[0041] The spring telescopic pin 43 in the positioning support mechanism 4 can be pre-adjusted in height according to the preset hole spacing. After drilling the first set of holes, simply insert the spring telescopic pin 43 into the drilled holes to automatically position the second set of holes, without relying on external tools such as tape measures or levels, thus completely eliminating manual measurement errors.

[0042] Furthermore, by rotating the adjusting screw 422, the adjusting block 423 can be moved up and down, thereby adjusting the height of the spring telescopic pin 43. This design can quickly meet the different requirements of various photovoltaic cylinders for the spacing of the upper and lower through holes without changing equipment or additional accessories, greatly reducing equipment limitations.
