[0002] Photovoltaic glass has the characteristics of high strength, high light transmittance and high weather resistance, and is an important packaging material for solar panels. Photovoltaic glass uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. This conversion process does not require a thermal process, but directly converts light energy into electrical energy. Photovoltaic power generation systems have two modes: independent operation and grid-connected operation. They can be applied to large-scale centralized ground photovoltaic power generation systems as well as distributed industrial and commercial enterprise factory rooftops and residential rooftop photovoltaic power generation systems.

[0003] The photovoltaic glass covered with the photovoltaic module after tempering can make the photovoltaic module withstand greater wind pressure, sandstorm, hail, large temperature difference between day and night and harsh environment, and protect the solar cells. At the same time, the photovoltaic glass after coating has the characteristics of high light transmittance, which can meet the needs of solar cells to generate more electricity.

[0004] In the production process of photovoltaic glass, the raw materials go through a series of process flows to become glass ribbons, which are then cut and broken into sheet glass plates. The glass plates are then further processed and cut into suitable sizes before they can be used in photovoltaic modules. Sheet glass plates are generally cut with a cutter wheel, which wears out when cutting glass. After long-term use, the cutter wheel is severely worn and needs to be replaced with a new one. To ensure the cutting quality, the cutter wheel needs to be replaced regularly. When replacing a traditional cutter wheel, the cutter wheel needs to be removed and then reinstalled after replacement. The whole process is cumbersome, time-consuming and labor-intensive. The overall size of the cutter wheel and props is small, which tests the technical level of employees when replacing them. The technical level of employees is high, which affects the overall replacement efficiency. Summary of the invention

[0024] Please also read Figures 1 to 6, the photovoltaic glass cutting tool quick tool changing device provided in this specification is now described. The photovoltaic glass cutting tool quick tool changing device includes a tool holder 1, a tool head assembly 2 and a lifting assembly 3. A fixing groove 11 is provided at the bottom of the tool holder 1, a receiving hole 12 is provided on the side wall of the fixing groove 11, and a pusher 13 is provided in the receiving hole 12, and the pusher 13 can move in a direction perpendicular to the axis of the fixing groove 11; the tool head assembly 2 has a tool holder 21 and a tool wheel 22 rotatably provided at the bottom of the tool holder 21, and the rotation axis of the tool wheel 22 is perpendicular to the up and down direction; the tool holder 21 is inserted into the fixing groove 11, and a snap-in groove 211 is provided on the outer periphery of the tool holder 21, and the pusher 13 is snap-fitted with the snap-in groove 211 to limit the displacement of the tool holder 21 in the up and down direction; the lifting assembly 3 includes a lifting drive 31, and a lifting end that can be extended and retracted up and down is provided at the bottom of the lifting drive 31, and the bottom of the lifting end is connected to the tool holder 1, and the top of the lifting drive 31 is connected to the cutting equipment.

[0025] It should be noted that this device is installed on the moving axis of the cutting equipment, and the cutting equipment is a cutting machine, which drives the device to move in the horizontal direction. The lifting drive 31 drives the knife seat 1 to move up and down. The lifting drive 31 and the cutting machine cooperate to drive the knife wheel 22 to move to any position, ensuring free cutting on the photovoltaic glass.

[0026] It should be noted that the lifting drive member 31 is a telescopic cylinder, a piston rod is arranged at the bottom of the telescopic cylinder, the bottom end of the piston rod forms a lifting end, a connecting groove is opened at the top of the tool holder 1 corresponding to the piston rod, a connecting hole is arranged on the side wall of the connecting groove, the bottom of the piston rod is inserted into the connecting groove, and a locking screw is arranged in the connecting hole to firmly fix the piston rod and the tool holder 1 together.

[0027] It should be noted that a groove is provided at the bottom of the tool holder 21, and the cutter wheel 22 is arranged in the groove by rotating the cutter shaft, and the bottom of the cutter wheel 22 protrudes from the groove, and the two ends of the cutter shaft are respectively rotated to connect the side walls of the groove.

[0028] It should be noted that, in the present application, "inward" refers to the direction from the outer periphery of the tool holder 1 to the central axis of the tool holder 1 , and "outward" refers to the direction from the central axis of the tool holder 1 .

[0029] In specific implementation, the present application replaces the cutter wheel 22 by plugging and unplugging the cutter holder 21. The cutter holder 21 is larger than the cutter wheel 22 and is easy to replace. The cutter wheel 22 can be removed from the cutter holder 21 in an offline process. In the photovoltaic glass cutting process, only the cutter holder 21 needs to be quickly replaced without affecting the working cycle. After the cutter holder 21 is disassembled, a new cutter wheel 22 is installed to improve the utilization rate of the cutter holder 21 and reduce the manufacturing cost.

[0030] Compared with the prior art, the photovoltaic glass cutting tool quick tool changing device provided in this embodiment is provided with a pluggable tool holder 1 and a tool head assembly 2. The pusher 13 in the tool holder 1 moves inward and engages with the engaging groove 211 on the tool holder 21 of the tool head assembly 2, so that the tool holder 21 is firmly fixed on the tool holder 1. The bottom of the tool holder 21 rotates and connects to the cutter wheel 22, and the tool holder 1 is driven up and down by the lifting end to drive the cutter wheel 22 up and down, thereby adjusting the position of the cutter wheel 22. When the cutter wheel 22 needs to be replaced, the tool holder 21 is pulled out of the tool holder 1, a new tool holder 21 is inserted, and the pusher 13 is engaged with the new engaging groove 211, so that a quick and effective replacement is achieved. The difficulty of replacing the tool holder 21 is lower than that of replacing the cutter wheel 22, and the whole operation process is simple, which greatly reduces the requirements for the technical level of employees; the worn cutter wheel 22 can be replaced offline, and only the tool holder 21 needs to be replaced online, so that employees can quickly replace the tool holder 21, which improves the replacement efficiency.

[0031] In some embodiments, see Figure 3 , the accommodating hole 12 passes through the knife holder 1, and the knife holder 1 also includes an adjusting member 14 and an elastic member 15. The adjusting member 14 is arranged at one end of the accommodating hole 12 away from the fixing groove 11; the two ends of the elastic member 15 are respectively connected to the pushing member 13 and the adjusting member 14, and the elastic member 15 is configured with a preload force to push the pushing member 13 to move inward. The adjusting member 14 is adjustably fixed in the accommodating hole 12, and is used to limit the installation position of one end of the elastic member 15. After the knife holder 21 is inserted into the fixing groove 11, the elastic member 15 can push the pushing member 13 to move toward the knife holder 21 until the pushing member 13 abuts against the clamping groove 211. Under the action of the adjusting member 14 and the elastic member 15, the pushing member 13 is clamped and fixed to the knife holder 21, so as to ensure the stability of the knife wheel during use, and the knife holder 21 will not fall out of the fixing groove 11 easily.

[0032] Specifically, the adjusting member 14 is an adjusting screw, which is threaded into the accommodating hole 12 and can move spirally along the accommodating hole 12. When the tool holder 21 is inserted into the fixing groove 11, the pushing member 13 is engaged with the engaging groove 211, and the two ends of the elastic member 15 are respectively positioned by the pushing member 13 and the adjusting member 14. At this time, the position of the adjusting member 14 in the accommodating hole 12 can be changed by screwing the adjusting member 14. When the adjusting member 14 is moved inward, the elastic member 15 is compressed, so that the elastic member 15 further applies pressure inward to the pushing member 13 to tighten the tool holder 21. When the adjusting member 14 is moved outward, the accommodating space of the elastic member 15 becomes longer, the pre-tightening force configured for the elastic member 15 becomes smaller, and the abutting force of the pushing member 13 on the snap-in groove 211 becomes smaller, which makes it convenient for the staff to remove the tool holder 21. After replacing the new tool holder 21, the adjusting member 14 is rotated inward to compress the elastic member 15. The elastic member 15 pushes the pushing member 13 to snap into the snap-in groove 211, and the tool holder 21 is firmly fixed.

[0033] Optionally, the elastic member 15 is a spring, which has good deformation continuity, high strength, and can be used for a long time, meeting the requirements of the elastic member 15. Of course, the elastic member 15 can also be other components with good elasticity, such as high temperature resistant rubber, as long as it can push the pushing member 13 to press against the clamping groove 211, and they will not be listed one by one here.

[0034] In specific implementation, the knife holder 1 is a cylindrical component, which is convenient for opening a hole and holding, and increases the convenience of replacement.

[0035] In some embodiments, see Figure 3 and Figure 4 There are multiple accommodating holes 12, and the multiple accommodating holes 12 are arranged around the central axis of the fixing groove 11, and there are correspondingly multiple pushing members 13. In this embodiment, multiple accommodating holes 12 are arranged to abut and fix the tool holder 21 from all sides of the tool holder 21, increase the force uniformity of the tool holder 21, and improve the fixing effect of the tool holder 21.

[0036] Specifically, two accommodating holes 12 are provided, the tool holder 1 is a cylindrical component, the axis of the fixing groove 11 overlaps with the central axis of the tool holder 1, the accommodating holes 12 extend radially of the tool holder 1, and the two accommodating holes 12 are symmetrically arranged along the central axis of the tool holder 1 to improve the force uniformity of the tool holder 21.

[0037] The accommodating holes 12 may also be arranged in three or four, as long as the plurality of accommodating holes 12 are ensured to evenly surround the central axis of the knife seat 1 .

[0038] In some embodiments, the pusher 13 is a ball, and the clamping groove 211 is in conformal contact with the push surface of the pusher 13. The outer circumference of the ball is uniform, and the tool holder 21 can easily cooperate with the ball whether it is rising or falling. The ball and the clamping groove 211 will not get stuck during the up and down misaligned movement, ensuring that the tool holder 21 can be replaced normally.

[0039] In a specific implementation, the pushing surface of the pushing member 13 refers to the side surface of the pushing member 13 abutting against the engaging groove 211 .

[0040] In some embodiments, see Figure 2 The horizontal cross-sectional area of ​​the tool holder 21 gradually decreases from top to bottom. The bottom of the tool holder 21 is connected to the cutter wheel 22. Reducing the bottom area of ​​the tool holder 21 can reduce the weight of the tool holder 21 and reduce the cost. On the other hand, it can avoid the collision between the tool holder 21 and the photovoltaic glass, ensuring that only the cutter wheel 22 contacts the photovoltaic glass during movement, avoiding scratching the photovoltaic glass and ensuring the cutting quality.

[0041] For specific implementation, see Figure 2 The vertical section of the tool holder is a right-angled trapezoid, the small end of the right-angled trapezoid faces downward, and the cutter wheel 22 is installed on the small end.

[0042] In some embodiments, referring to the figure, the cutter wheel 22 is a toothed diamond cutter wheel 22. The toothed diamond cutter wheel 22 has high strength and hardness and can easily cut photovoltaic glass.

[0043] It should be noted that the glass cutter wheel with teeth made of diamond material has high precision, high penetration, high compressive strength, narrow cutting slit, smooth cutting line and flat cross section. These characteristics make the diamond cutter wheel with teeth perform well in the cutting process and is suitable for cutting a variety of brittle materials.

[0044] The toothed diamond wheel has fewer teeth, a tooth depth of 1.0-1.8μm, and a sharp edge, which can meet the dual requirements of high penetration and high compressive strength. During cutting, the cutting pressure is stable, the cutting line is smooth, and the cross section is flat, ensuring the cutting quality. When cutting glass, the toothed diamond wheel has a narrower cutting seam and minimal damage on both sides of the cutting line, which is suitable for cutting ultra-thin glass. The cut glass has a higher Bending value and yield rate, ensuring the cutting quality of the glass.

[0045] In some embodiments, see Figure 1 The lifting drive 31 is a cylinder, and the lifting assembly 3 further includes a proportional valve 32, which is connected to the cylinder to control the change of gas in the cylinder. The proportional valve 32 can adjust the pressure in the cylinder to adjust the moving line distance of the lifting end of the lifting drive 31, so that the cutter wheel 22 can be lifted up and down on the surface of the photovoltaic glass to achieve the effect of cutting the photovoltaic glass.

[0046] During specific implementation, the cylinder is divided into a first chamber and a second chamber from top to bottom, and a piston plate is arranged between the first chamber and the second chamber. The outer periphery of the piston plate is slidably fitted with the inner chamber of the cylinder, and the lower end surface of the piston plate is connected to the piston rod. The proportional valve 32 is connected to the first chamber through an air pipe. The air pressure entering the first chamber is adjusted by the proportional valve 32, thereby changing the volume of the first chamber. The volume of the first chamber increases, causing the piston plate to move downward, and then the piston rod drives the tool holder 21 to move downward.

[0047] In some embodiments, see Figure 3 and Figure 5 The cutter head assembly 2 also includes a connecting rod 23 and a bearing 24. The top of the connecting rod 23 extends into the fixed groove 11, and a snap-in groove 211 is provided on the outer periphery of the connecting rod 23; the upper and lower ends of the bearing 24 are rotatably connected to the bottom of the connecting rod 23 and the top of the tool holder 21 respectively, and the rotation axis of the bearing 24 is parallel to the up and down direction. The two ends of the connecting rod 23 are respectively connected to the tool holder 21 and the tool seat 1, which reduces the difficulty of disassembly and installation. The connecting rod 23 is small in size and can be made into a cylindrical shape, which can be adapted to the fixed groove 11, reducing the difficulty of installation. The provision of the bearing 24 allows the tool holder 21 to rotate along the circumference of the connecting rod 23, which facilitates the tool holder 21 to drive the cutter wheel 22 to turn during use.

[0048] In some embodiments, see Figure 3 The connecting rod 23 is a magnetic rod; a magnet 16 is provided at the top of the fixing groove 11, and the magnet 16 attracts the connecting rod 23 to limit the circumferential rotation of the connecting rod 23. The connecting rod 23 is configured as a magnetic rod, which can be attracted and fixed to the magnet 16. The magnet 16 is fixed in the fixing groove 11, so that the connecting rod 23 does not rotate along its own circumferential direction, thereby ensuring the connection stability of the connecting rod 23 during the cutting process.

[0049] In some embodiments, see Figure 4 and Figure 5 The top of the connecting rod 23 is formed with a first guide surface 231 which gradually tilts outward from top to bottom, and the opening of the fixing groove 11 forms a second guide surface 111 corresponding to the first guide surface 231. The second guide surface 111 enlarges the opening area of ​​the fixing groove 11, making it easier for employees to insert the connecting rod 23. The top of the connecting rod 23 is provided with the first guide surface 231 to guide the connecting rod 23 to be inserted upward into the fixing groove 11, thereby reducing the collision between the connecting rod 23 and the fixing groove 11 and protecting the connecting rod 23 and the fixing groove 11.

[0050] The following is an embodiment of the present application: For cutting photovoltaic glass, a precise lifting drive 31 is set. During normal production, the lifting drive 31 is installed on the cutting equipment, and the cutter head assembly 2 is installed on the cutter holder 1 and can be quickly replaced. The cutter holder 1 is installed on the lifting end of the lifting drive 31. The cutter wheel 22 can be raised and lowered by adjusting the pressure regulating proportional valve 32, and the pressure of the cutter wheel 22 when cutting photovoltaic glass can be accurately controlled. When the cutter wheel 22 is worn and needs to be replaced, the cutter head assembly 1 can be manually pulled out, and a new cutter head assembly 1 can be quickly inserted to work. The worn cutter wheel 2 can be replaced offline, which is convenient and quick, and improves production efficiency.

[0051] The lifting drive 31 of the device is a precision cylinder, which is installed on the moving shaft of the cutting machine. The pressure regulating proportional valve 32 is connected to the precision cylinder through an air pipe and can precisely control the pressure of the precision cylinder. The knife seat 1 is installed on the cylinder rod of the precision cylinder and is fastened by a set screw; the lower part of the knife seat 1 is a fixed groove 11 for installing the cutter head assembly 2, and a strong magnet 16 is installed at the top of the fixed groove 11. There are balls or pushers 13 on both sides of the fixed groove 11. The balls are pushed tightly by the elastic member 15, and the elastic member 15 is equipped with an adjustment member 14 on the outside to adjust the thrust. The adjustment member 14 is an adjustment screw. The tool holder 21 of the cutter head assembly 2 is installed in the fixed groove 11 through the connecting rod 23. The connecting rod 23 is made of magnetic material. The outer periphery of the connecting rod 23 is provided with a clamping groove 211. After being inserted into the fixed groove 11 of the cutter holder 1, the ball bearing can clamp the clamping groove 211 to prevent the tool holder 21 from falling off, and the strong magnet 16 on the top can suck the connecting rod 23 tightly to prevent the connecting rod 23 from shaking up and down in the cutter holder 1. The lower part of the connecting rod 23 is connected to the tool holder 21 through the bearing 24, so that the tool holder 21 can rotate universally around the bearing 24, which is convenient for cutting and reversing. A knife shaft is installed at the bottom of the tool holder 21, and a knife wheel 22 is installed on the knife shaft. The glass is cut by the knife wheel 22.

[0052] During normal production, the lifting drive 31 performs cutting action through the cutting machine motion axis, and the cylinder rod of the lifting drive 31 is raised and lowered by adjusting the pressure regulating proportional valve 32, thereby driving the cutter head assembly 2 and the cutter seat 1 to rise and fall on the glass surface, and the pressure of the cutter wheel 22 when cutting the glass can be accurately controlled. When the cutter wheel 22 is worn and needs to be replaced, the cutter head assembly 2 is manually pulled out of the cutter seat 1, and a new cutter head assembly 2 is quickly inserted to work. The strong magnet 16 of the cutter seat 1 absorbs the connecting rod 23, and the ball is clamped in the clamping groove 211 of the connecting rod 23, so that the cutter head assembly 2 is securely installed and can be quickly plugged in and replaced. The replaced worn cutter wheel 22 can be replaced offline, which is convenient and quick, and improves production efficiency.
