Description

Technical Field

[0001] This utility model relates to the field of stove explosion-proof film cutting technology, and in particular to a stove explosion-proof film cutting device. Background Technology

[0002] In some industrial manufacturing applications, cutting along certain contours is necessary. These contours may have geometric deviations or be irregular. Therefore, a method is needed to ensure the cutting position remains correct. A common solution is manual cutting, while a more advanced solution uses visual inspection technology to determine the contour trajectory and then drives a cutting device to perform interpolation based on the contour trajectory data to complete the cut. Currently, cutting holes for explosion-proof films is done manually using a utility knife along the edge of the glass hole. When cutting these holes, the operator can see the glass hole position, requiring two people to operate the cutting device, cutting along the inner wall of the glass hole. Holes on the glass panel are drilled manually, with the operator controlling the position of the glass panel. Since the position of the glass hole is different on each glass panel, the cutting position for the explosion-proof film needs to be accurately located. Existing technology uses visual imaging to record the position of the holes on the glass panel, converting the video data into specific information and transmitting it to a central processor. The central processor then controls the cutting head to automatically cut to the glass hole position. However, different lighting conditions and reflections can cause problems in the visual imaging processing, posing a significant challenge to programming, requiring advanced programming skills and incurring high labor costs. Utility Model Content

[0003] In view of this, the present invention provides a stove explosion-proof film cutting device, which has a simple structure, low cost, high working efficiency, and can realize the cutting action of irregular contours.

[0004] A stove explosion-proof film cutting device includes a chassis. A first device and a second device are sequentially distributed on the chassis from one side to the other. The first device includes a glass panel positioning and clamping mechanism, within which a glass panel conveying mechanism is provided. Stove explosion-proof film cutting mechanisms are respectively provided on both sides of the glass panel positioning and clamping mechanism. The stove explosion-proof film cutting mechanisms are used to cut holes for the stove holes and button holes corresponding to the explosion-proof film on the glass panel. The second device is a glass panel output mechanism, which is connected to the glass panel conveying mechanism and is used to receive and output the glass panel with the completed explosion-proof film cutting from the glass panel conveying mechanism. In this embodiment, a first device and a second device are sequentially arranged on the chassis. A glass panel positioning and clamping mechanism is provided at the first device, and a glass panel conveying mechanism is provided inside the glass panel positioning and clamping mechanism. The glass panel positioning and clamping mechanism is used to clamp the glass panel to position it. After positioning, the glass panel is cut by a stove explosion-proof film cutting mechanism. After cutting, the glass panel is conveyed forward by the glass panel conveying mechanism to the glass panel output mechanism on the second device for output. This utility model has a reasonable overall structure, simple composition, small space occupation, and realizes automatic cutting of explosion-proof film on glass panels. It is not only low in cost, but also highly efficient and of good quality.

[0005] Furthermore, the glass panel positioning and clamping mechanism includes two positioning and clamping units distributed opposite to each other. The two positioning and clamping units are located on both sides of the glass panel conveying mechanism. Each positioning and clamping unit includes a clamping and positioning frame. The top surface of the clamping and positioning frame has two parallel clamping slide rail assemblies. The clamping slide rail assembly is equipped with a clamping plate, and the clamping plate is equipped with several clamping pulleys. A clamping cylinder is fixed to the outer side of the clamping and positioning frame, and the pushing end of the clamping cylinder is connected to the clamping plate.

[0006] In this embodiment, two positioning and clamping units are arranged opposite to each other on the outside of the glass panel conveying mechanism. After the clamping cylinder is driven, the positioning and clamping units on both sides clamp the glass panel from both sides, so that the clamping of the glass panel is stable, which prepares for the hole cutting operation and helps to improve the hole cutting efficiency and quality.

[0007] The glass panel conveying mechanism is located between two positioning and clamping units. This mechanism is a conveyor belt type, including a conveying cylinder mounted on a conveying positioning frame. Two parallel-distributed pulley-type conveying assemblies are connected to the conveying positioning frame via a linkage rod. The glass panels to be conveyed are placed on the conveyor belts on both sides of the pulley-type conveying assemblies. In this embodiment, the glass panel conveying mechanism uses parallel-distributed pulley-type conveying assemblies for conveying, resulting in a reasonable structural distribution and stable conveying.

[0008] The stove explosion-proof film cutting mechanism includes a positioning component and a movable component. The movable component includes a movable plate that moves along the positioning component and a cutting blade unit. The cutting blade unit includes a cutting blade and a guide wheel that are fixedly distributed.

[0012] The lead screw assembly includes a rotatable lead screw body, a lead screw seat that moves along the lead screw, and a drive plate connected to a first movable plate fitted on the lead screw seat. The lead screw seat moves along the lead screw under the drive of a lead screw drive motor, thereby causing the drive plate and the first movable plate to move radially away from or compress the buffer spring. An opening is provided at the connection hole between the drive plate and the lead screw seat. The size of the opening is between the diameter of the lead screw body and the diameter of the movable seat, so that the drive plate can be removed from the lead screw after it moves out of the movable seat along the lead screw direction.

[0013] The cutting unit also includes a cutting motor and a cutting fixture. The cutting motor is mounted on a motor mounting bracket. The output of the cutting motor is connected to the cutting fixture via an eccentric wheel. The cutting motor drives the cutting blade to reciprocate up and down through the eccentric wheel and the cutting fixture.

[0015] In this embodiment, the stove explosion-proof film cutting mechanism comprises a first cutting mechanism and a second cutting mechanism. The first cutting mechanism is used to cut stove holes on the explosion-proof film. The first cutting mechanism includes a first positioning component, which is connected to a first movable component and a first driving mechanism. The first positioning component includes a horizontally distributed first fixing plate and a second fixing plate fixed to the bottom of the first fixing plate and perpendicular to the first fixing plate. The first fixing plate is connected to the first driving mechanism, and the second fixing plate is connected to the first movable component.

[0016] The first movable component includes a first radial movable unit, a first vertical movable unit, and a first cutting unit.

[0017] The first radial movable unit includes a first movable plate, a radial drive unit, and a lead screw assembly. The first movable plate is driven by the first radial drive unit and the lead screw assembly to move radially along the first positioning assembly.

[0018] The first movable plate is radially movably connected to the second fixed plate via a first slide rail assembly. The first slide rail assembly consists of a first slide rail and a first slider. The first movable plate slides radially along the first slide rail via the first slider.

[0019] The radial drive unit includes a fixed frame mounted on a second positioning plate. A radial drive motor is mounted on the fixed frame. The radial drive motor is connected to a lead screw assembly via a belt assembly. The lead screw assembly is connected to a first movable plate. The radial drive unit drives the first movable plate to move radially along a first slide rail via the lead screw assembly. Specifically, the lead screw assembly is connected to the first movable plate via a drive plate. The first movable plate has a T-shaped embedded movable groove. The drive plate is sleeved on the lead screw seat in the lead screw assembly. One end of the drive plate is installed in a vertical groove embedded in the movable groove. The width of the vertical groove is greater than the width of the drive plate, allowing the drive plate to move in the width direction within the vertical groove. The end of the drive plate away from the vertical groove has an opening. The opening distance of the opening is between the outer diameter of the lead screw body and the outer diameter of the lead screw seat in the lead screw assembly, so that the drive plate can be quickly removed from the lead screw body after moving along the lead screw seat and disengaging from the lead screw seat. The embedded movable slot also includes a transverse slot, and a compression component is provided in the transverse slot. The compression component includes a radial positioning shaft, and a buffer spring is sleeved on the radial positioning shaft.

[0020] The first vertical movable unit includes a first slide rail cylinder and a first connecting frame. The first slide rail cylinder is mounted on the first movable plate, and the first connecting frame is connected to the first slide rail cylinder vertically via a slider.

[0021] The first cutting unit includes a first hole-cutting cutter and a first guide wheel, both fixedly positioned, as well as a first cutting motor and a first cutting fixture. The first cutting motor is mounted on a first connecting frame, and its output end is connected to the first cutting fixture via a first eccentric wheel. The first cutting motor drives the first hole-cutting cutter to reciprocate up and down through the eccentric wheel and the fixture. The first guide wheel is connected to a first slide rail cylinder via the connecting frame. Driven by a radial drive unit through a first movable plate, the first guide wheel moves radially along the first slide rail towards the inner wall of the glass hole, ensuring that the first hole-cutting cutter maintains a suitable position with the inner wall of the glass during its reciprocating motion and preventing contact with the inner wall. The first hole-cutting cutter and the first guide wheel are driven by the first movable plate to move towards the inner wall of the glass hole corresponding to the stove hole on the glass panel, causing the first guide wheel to abut against the inner wall of the glass hole.

[0022] The first driving mechanism includes an XYZ three-axis driving mechanism and a rotary driving mechanism. The XYZ three-axis driving mechanism drives the first movable component to translate along the X, Y, and Z axes to the cutting position through the first positioning component. The rotary driving mechanism drives the first movable component to rotate through the first positioning component.

[0023] In this embodiment, the principle of cutting the stove hole on the explosion-proof film is as follows:

[0024] The XYZ three-axis drive mechanism drives the first movable component and its first cutting blade to translate along the X-axis, Y-axis and Z-axis to the corresponding positions of the stove holes to be cut on the explosion-proof film through the first positioning component;

[0025] The first slide rail cylinder starts and drives the first cutting blade to move upward to lift the blade, so that the first cutting blade is removed from the explosion-proof membrane, preventing the first cutting blade from puncturing the explosion-proof membrane during the position adjustment process.

[0026] The radial drive unit drives the first movable plate and the first support wheel mounted on it to move to the inner wall of the glass stove hole on the glass panel corresponding to the stove hole position through the lead screw assembly. During this process, the compression component in the first radial movable unit plays a role in buffering and compressing the radial movement of the first support wheel. The setting of the compression component ensures that the first support wheel can rest against the inner wall of the glass stove hole.

[0027] The first slide rail cylinder starts and drives the first cutting blade to move downward to pierce the explosion-proof film. The first cutting blade motor drives the first cutting blade to move up and down reciprocatingly. The rotary drive mechanism drives the first cutting blade to rotate through the first positioning component, so that the first cutting blade can perform up and down reciprocating cutting to ensure the cutting quality.

[0028] The second cutting mechanism is used to cut button holes on the explosion-proof film. The second cutting mechanism includes a second positioning component, which is connected to the second movable component and the second drive mechanism. The second positioning component includes a horizontally distributed third fixing plate and a fourth fixing plate fixed to the bottom of the third fixing plate and perpendicular to the third fixing plate.

The third slide rail cylinder is mounted on the second movable plate, and the third movable plate is radially slidably connected to the third slide rail cylinder via a slider. The second cutting unit includes a second hole-cutting cutter and a second guide wheel distributed in a fixed position. The second hole-cutting cutter and the second guide wheel are driven by the third movable plate to move towards the inner wall of the glass hole corresponding to the button hole on the glass panel, so that the second guide wheel abuts against the inner wall of the glass hole. The second drive mechanism also includes an XYZ three-axis drive mechanism and a rotary drive mechanism. The XYZ three-axis drive mechanism drives the second movable component to translate along the X, Y, and Z axes to the hole-cutting position via a second positioning component. The rotary drive mechanism drives the second movable component to rotate via the second positioning component to perform the hole-cutting operation.

[0030] The second cutting unit also includes a second cutting blade mounting bracket, a second cutting blade motor, and a second motor mounting bracket. The second motor mounting bracket is connected to the bottom of the second movable plate. Both the second motor mounting bracket and the third movable plate are driven by the second movable plate to move up and down along the second slide rail cylinder on the fourth fixed plate. The second cutting blade motor is mounted on the second motor mounting bracket, and its output end is connected to the second cutting blade mounting bracket via a second eccentric wheel. The second cutting blade motor drives the second hole-cutting blade to reciprocate up and down through the second eccentric wheel and the second cutting blade mounting bracket. The fourth movable plate is connected to a second guide wheel via a second connecting bracket. The second guide wheel is driven by the fourth movable plate to move radially to the inner wall of the glass hole corresponding to the button hole, ensuring that the second hole-cutting blade maintains a suitable position with the inner wall of the glass during its up and down reciprocating motion and preventing it from contacting the inner wall of the glass hole.

[0031] Compared with existing technologies, this utility model has the following advantages: This utility model employs a method of adding a guide wheel at a certain distance from the cutter to form a cutter with the guide wheel fixed in position. This fixes the cutter relative to the guide wheel at a specific position that meets the cutting requirements. Regardless of how the cutter moves, it will move along the contour with the guide wheel, ensuring that the cutter will not contact the inner wall of the hole on the glass panel. This ensures that the cutter always moves in a relatively fixed position relative to the contour, achieving the required cutting action and ensuring cutting quality. This technical solution uses the addition of a guide wheel to achieve cutting of irregular contours. Its structure is simple, its working efficiency is high, and its cost is significantly reduced compared to existing solutions using visual inspection methods. Attached Figure Description

A glass panel positioning and clamping mechanism 210 is provided at the first device 200, and a glass panel conveying mechanism 220 is provided inside the glass panel positioning and clamping mechanism 210. The glass panel positioning and clamping mechanism 210 is used to clamp the glass panel to position it. After positioning, the glass panel is cut by the stove explosion-proof film cutting mechanism. After the glass panel is cut, it is conveyed forward by the glass panel conveying mechanism 220 to the glass panel output mechanism on the second device 300 for output. This utility model has a reasonable overall structure, simple composition, small space occupation, and realizes automatic cutting of the explosion-proof film on the glass panel. It is not only low in cost, but also highly efficient and of good quality.

[0046] Reference Figures 1 to 3This embodiment is a non-limiting embodiment. The glass panel positioning and clamping mechanism 210 includes two positioning and clamping units 211 that are distributed opposite to each other. The two positioning and clamping units 211 are distributed on both sides of the glass panel conveying mechanism 220. The positioning and clamping unit 211 includes a clamping and positioning frame 2111. The top surface of the clamping and positioning frame 2111 has two parallel clamping slide rail assemblies 2112. The clamping slide rail assembly 2112 is equipped with a clamping plate 2113. The clamping plate 2113 is equipped with a plurality of clamping pulleys 2114. A clamping cylinder 2115 is fixed on the outer side of the clamping and positioning frame 2111. The pushing end of the clamping cylinder 2115 is connected to the clamping plate 2113. In this embodiment, two positioning and clamping units 211 are arranged opposite to each other on the outside of the glass panel conveying mechanism 220. After the clamping cylinder 2115 is driven, the positioning and clamping units 211 on both sides clamp the glass panel from both sides, so that the clamping of the glass panel is stable, which prepares for the hole cutting operation and helps to improve the hole cutting efficiency and quality.

[0047] Reference Figure 1 , Figure 2 This embodiment is a non-limiting embodiment. The glass panel conveying mechanism 220 is located between two positioning and clamping units 211. The glass panel conveying mechanism 220 is a conveyor belt type conveying mechanism. Specifically, the glass panel conveying mechanism 220 includes a conveying cylinder 222 mounted on a conveying positioning frame 221. Two parallel-distributed pulley type conveying assemblies 224 are connected to the conveying positioning frame 221 via a linkage rod 223. The glass panel to be conveyed is placed on the conveyor belts on both sides of the pulley type conveying assembly 224. In this embodiment, the glass panel conveying mechanism 220 uses parallel-distributed pulley type conveying assemblies 224 for conveying. Its structure is reasonably distributed and the conveying is stable. The pulley type conveying assembly 224 is a conventional pulley type conveying structure composed of a drive wheel, a transmission wheel, and a conveyor belt, which will not be described in detail here.

[0048] Reference Figure 1 , Figure 2 , Figures 4 to 6This embodiment is a non-limiting embodiment. The stove explosion-proof film cutting mechanism includes a positioning component and a movable component. The movable component includes a movable plate that moves laterally along the positioning component and a cutting unit mounted on the movable plate. The cutting unit includes a cutting blade and a guide wheel that are fixedly distributed. The cutting blade and the guide wheel are driven by the movable plate to move towards the inner wall of the corresponding glass hole on the glass panel, so that the guide wheel abuts against the inner wall of the glass hole. The positioning component in the cutting mechanism is connected to a driving mechanism. The driving mechanism is an XYZ three-axis driving mechanism and a rotary driving mechanism. The XYZ three-axis driving mechanism drives the cutting mechanism to translate along the X, Y, and Z axes to the cutting position through the positioning component. The rotary driving mechanism drives the cutting mechanism to rotate through the positioning component to cut the hole. For irregular hole cutting, the distance between the cutting blade and the inner wall of the glass hole is required to be less than 0.5mm, but it cannot touch or contact the inner wall of the glass hole. In this embodiment, the irregular holes are the button holes and stove holes on the glass explosion-proof film on the stove, i.e., glass holes. For each piece of glass, the position of the circular hole varies slightly depending on the type of glass, resulting in different cutting positions for different applications. However, the machine cuts from the same fixed position. We know that the inner wall of the circular hole is curved. In this embodiment, a guide roller is used to first press against the inner wall of the glass circular hole, creating a certain gap between the cutting blade and the guide roller. This ensures that the position of the blade and the guide roller remains constant, thus maintaining a suitable position between the blade and the inner wall of the glass without contacting it. Specifically, in this embodiment, the stove explosion-proof film cutting mechanism consists of a first cutting mechanism 230 and a second cutting mechanism 240, wherein, referring to… Figures 4 to 6 The first cutting mechanism 230 is used to cut the stove hole 11 on the explosion-proof film.

The rotary drive mechanism drives the first movable component 232 to rotate through the first positioning component 231.

[0056] Reference Figures 1 to 6 In this embodiment, the principle of the first cutting mechanism 230 cutting the stove hole on the explosion-proof film is as follows:

[0057] The XYZ three-axis drive mechanism drives the first movable component 232 and its first cutting blade 23231 to translate along the X-axis, Y-axis and Z-axis to the corresponding positions of the stove holes to be cut on the explosion-proof film through the first positioning component 231;

[0058] The first slide rail cylinder 23221 is activated, which drives the first cutting blade 23231 to move upward to lift the blade, so that the first cutting blade 23231 is removed from the explosion-proof membrane, preventing the first cutting blade 23231 from puncturing the explosion-proof membrane during the position adjustment process.

[0059] The radial drive unit 23212 drives the first movable plate 23211 and the first support wheel 23232 mounted thereon to move to the inner wall of the glass stove hole on the glass panel corresponding to the stove hole position through the lead screw assembly 23213. During this process, the compression component 23214 in the first radial movable unit 2321 plays a role in buffering and compressing the radial movement of the first support wheel 23232. The setting of the compression component 23214 ensures that the first support wheel 23232 can rest against the inner wall of the glass stove hole.

[0060] The first slide rail cylinder 23221 starts and drives the first hole-cutting cutter 23231 to move downward to pierce the explosion-proof film. The first cutter motor 23233 drives the first hole-cutting cutter 23231 to perform up-and-down reciprocating motion. The rotary drive mechanism drives the first hole-cutting cutter 23231 to rotate through the first positioning component 231, so that the first hole-cutting cutter 23231 performs up-and-down reciprocating hole cutting to ensure the hole cutting quality.

[0061] Reference Figure 1 , Figure 2 , Figures 7 to 10 In a non-limiting embodiment of this utility model, the second cutting mechanism 240 is used to cut out the button hole 12 on the explosion-proof film. The second cutting mechanism 240 includes a second positioning component 241, which is connected to the second movable component 242 and the second driving mechanism 243 respectively. The second positioning component 241 includes a horizontally distributed third fixing plate 2411 and a fourth fixing plate 2412 fixed to the bottom of the third fixing plate 2411 and perpendicular to the third fixing plate 2411. The third fixing plate 2411 is connected to the second driving mechanism 243, and the fourth fixing plate 2412 is connected to the second movable component 242.

[0062] Reference Figure 1 , Figure 2 , Figures 7 to 10In a non-limiting embodiment of this utility model, the second movable component 242 includes a second radial movable unit 2421, a second vertical movable unit 2422, and a second cutting unit 2423. The second vertical movable unit 2422 includes a second slide rail cylinder 24221 and a second movable plate 24222. The second slide rail cylinder 24221 is mounted on the fourth fixed plate 2412, and the second movable plate 24222 is slidably connected to the second slide rail cylinder 24221 via a slider. The second radial movable unit 2421 includes a third movable plate 24211 and a third sliding plate 24222. The third slide rail cylinder 24212 is mounted on the second movable plate 24222. The third movable plate 24211 is radially slidably connected to the third slide rail cylinder 24212 via a slider. The second cutting unit 2423 includes a second hole-cutting cutter 24231 and a second guide wheel 24232, which are fixedly distributed. The second hole-cutting cutter 24231 and the second guide wheel 24232 are driven by the third movable plate 24211 to move towards the inner wall of the glass hole corresponding to the button hole 12 on the glass panel, so that the second guide wheel 24222 abuts against the inner wall of the glass hole. The second drive mechanism 243 also includes an XYZ three-axis drive mechanism and a rotary drive mechanism. The XYZ three-axis drive mechanism drives the second movable component 242 to translate along the X, Y, and Z axes to the hole-cutting position through the second positioning component 241. The rotary drive mechanism drives the second movable component 242 to rotate through the second positioning component 241 to perform the hole-cutting operation.

[0063] Reference Figure 1 , Figure 2 , Figures 7 to 10In a non-limiting embodiment of this utility model, the second cutting unit 2423 further includes a second cutting bracket 24235, a second cutting motor 24233, and a second motor bracket 24234. The second motor bracket 24234 is connected to the bottom of the second movable plate 24222. Both the second motor bracket 24234 and the third movable plate 24211 are driven by the second movable plate 24222 to move up and down along the second slide rail cylinder 24221 on the fourth fixed plate 2412. The second cutting motor 24233 is mounted on the second motor bracket 24234. The output end of the second cutting motor 24233 is connected to the second cutting bracket 24235 through the second eccentric wheel 24237. The second cutting motor 24233 drives the second hole cutting blade 24231 to reciprocate up and down through the second eccentric wheel 24237 and the second cutting bracket 24235. The fourth movable plate 24211 is connected to the second guide wheel 24232 via the second connecting frame 24236. The second guide wheel 24232 is driven by the fourth movable plate 24211 to move radially to the inner wall of the glass hole corresponding to the button hole 12, so as to ensure that the second cutting blade 24231 always maintains a suitable position with the inner wall of the glass during the up and down reciprocating motion, and to ensure that the second cutting blade 24231 will not contact the inner wall of the glass hole.

[0064] Reference Figures 1 to 10 In this embodiment, the cutting principle of the second cutting mechanism 240 in cutting the button hole 12 on the explosion-proof film is the same as that of the first cutting mechanism 230 in cutting the stove hole 11 on the explosion-proof film. The difference lies in the different positions of the radial and vertical movements, but this does not affect the cutting operation and will not be elaborated further here. In this embodiment, the first cutting mechanism 230 and the second cutting mechanism 240, while the cutter moves horizontally along the inner wall of the circular hole, also perform a downward cutting action in the vertical direction. The advantage of this arrangement in this embodiment is that if the cutter itself does not move up and down and only cuts horizontally, the cutting resistance will be very large, making it difficult to cut. Therefore, it is necessary to move horizontally in the circumferential direction while simultaneously moving vertically up and down to reduce the cutting resistance, make cutting easier, and improve work efficiency.
