Description

Technical Field

[0001] This invention relates to the field of laser processing equipment technology, and specifically to a laser processing device for glass doors. Background Technology

[0002] Glass doors are a special type of door, and their characteristics are determined by the properties of the glass itself. For example, tempered transparent glass provides complete transparency, while frosted glass provides semi-transparency. Glass doors are categorized into decorative glass doors, safety glass doors, energy-saving glass doors, coated glass doors, and sensor-operated glass doors, among others.

[0003] The core structure of a glass door consists of four main modules: glass panel, frame support, hardware accessories, and drive control system (automatic door). During the glass door manufacturing process, laser processing equipment is required. Laser processing of glass doors is a high-precision processing technology for the three core components: glass panel, metal frame, and hardware accessories. It has the advantages of non-contact processing, small heat-affected zone, and high processing accuracy, and can solve the pain points of traditional mechanical processing (cutting edge chipping, welding deformation, low engraving accuracy). Laser processing of glass doors mainly includes laser cutting, laser welding, laser drilling, and laser etching.

[0004] Chinese patent document CN205085542U discloses a laser cutting device for manufacturing glass door panels, including a frame, a laser emitter, and a cutting wheel. Several horizontally and evenly arranged conveyor rollers are arranged on one side of the frame. The cutting wheel is mounted on the frame and is positioned higher than the conveyor rollers. A gap is left between the cutting wheel and the conveyor rollers to accommodate the glass panel. The laser irradiation point of the laser emitter is located behind the cutting wheel, and the irradiation direction is on the same plane as the cutting wheel. A laser emitting mirror is also mounted on the frame.

[0005] During operation, the glass plate is placed on the conveyor roller for transport. The cutter wheel above the glass plate rotates and scratches the areas of the glass plate that need to be cut. The laser emitter emits a horizontal laser beam, which is reflected by a mirror and falls on the scratched area of ​​the glass plate. The laser energy rapidly heats up the glass at the irradiation point, and the thermal stress causes the glass edge to break. The unwanted edge material on the glass plate falls off, allowing the glass to reach the required size.

[0006] In the aforementioned technology, when laser processing is required on a glass door frame, the laser emitter moves to the position to be cut on the glass door frame and is located directly above a certain conveyor roller. When the laser emitter emits laser light to process the glass door frame, the molten part of the glass door frame will directly contact the surface of the conveyor roller below. In addition, the high-temperature waste generated during the processing of the glass door frame will also directly contact the conveyor roller, thereby causing damage to the surface of the conveyor roller or leaving metal residue. This will negatively affect the subsequent load-bearing and conveying of the glass door frame, and may even require frequent replacement and maintenance of the conveyor roller. Summary of the Invention

[0007] This invention provides a laser processing device for glass doors, aiming to solve the technical problem in the prior art where, when laser processing of a glass door frame is required, the laser emitter moves to the position to be cut on the glass door frame and is directly above a certain conveyor roller. When the laser emitter emits laser light to process the glass door frame, the molten part of the glass door frame directly contacts the surface of the conveyor roller below, and the high-temperature waste generated during the processing of the glass door frame also directly contacts the conveyor roller. This causes damage to the surface of the conveyor roller or leaves metal residue, which will negatively affect the subsequent load-bearing and conveying of the glass door frame, and may even require frequent replacement and maintenance of the conveyor roller.

[0008] A laser processing apparatus for glass doors according to the present invention includes a frame, on which a laser emitting head and a moving mechanism are mounted. The moving mechanism includes a main moving frame and a secondary moving frame, which are slidably connected to the frame and to the main moving frame. The laser emitting head is fixedly mounted on the secondary moving frame. Multiple conveying rollers are rotatably mounted on the frame, and these rollers are arranged horizontally. The glass door simultaneously contacts the upper sides of the multiple conveying rollers. Multiple adjusting mounting frames are slidably mounted on the frame in a vertical direction. Each conveying roller is rotatably connected to an adjusting mounting frame. An adjusting mechanism is also provided on the frame. When the laser emitting head is above a single conveying roller, the adjusting mechanism controls the adjusting mounting frame located on that conveying roller to move downwards, creating a gap between the conveying roller and the glass door.

[0009] The effect is as follows: When the glass door is placed on the conveyor rollers, all the conveyor rollers are originally at the same height, and the glass door is placed stably. When the moving mechanism moves the laser emitting head to be close to or above a certain conveyor roller, the adjusting mounting bracket on which this conveyor roller is located is lowered under the control of the adjusting mechanism, thereby separating it from the glass door and forming a gap. Due to the existence of this gap, when the part of the glass door directly below the laser emitting head is laser-cut, the high-temperature molten material generated will not directly contact the conveyor roller, which can effectively reduce the high-temperature damage to the conveyor roller. In addition, since the height of other conveyor rollers that are relatively far away from the laser emitting head remains unchanged during this process, the position of the glass door placed on multiple conveyor rollers can remain stable, and the laser processing can continue to proceed normally.

[0010] Preferably, the moving direction of the main moving frame is parallel to the arrangement direction of the multiple conveying rollers. The adjusting mechanism includes a support spring, a force-bearing block, and a pressure roller. One end of the support spring is connected to the frame, and the other end is connected to the adjusting mounting frame. The force-bearing block is fixedly connected to the adjusting mounting frame. The pressure roller is rotatably mounted on the main moving frame. The axis of the pressure roller is horizontal and perpendicular to the arrangement direction of the multiple conveying rollers. When the wheel surface of the pressure roller abuts against the force-bearing block, the force direction of the force-bearing block is inclined downward.

[0011] Its effect is as follows: during the movement of the main moving frame, when the laser emitting head approaches the top of a certain conveying roller, the wheel surface of the pressure roller can roll over the pressure block on the adjusting mounting frame where the conveying roller is located; the side of the pressure block contacts the pressure roller first, and the pressure roller has a vertically downward component in its contact force with the pressure block, thereby causing the pressure block and the adjusting mounting frame connected to the pressure block to move downward.

[0012] Preferably, a locking pin is slidably mounted on the frame, the sliding direction of the locking pin is perpendicular to the sliding direction of the adjusting mounting bracket, a locking slot is provided on the adjusting mounting bracket, a self-locking spring is connected between the locking pin and the frame, and in the natural state, one end of the locking pin is inserted into the locking slot, the locking pin is made of magnetic metal, and an unlocking magnet is fixedly connected to the main moving frame near the pressure roller, the unlocking magnet is located on the side of the locking pin away from the adjusting mounting bracket.

[0013] Its effect is as follows: when the locking pin is inserted into the locking slot, the adjusting mounting bracket cannot move up and down easily, and the conveying roller has a high stability. Before the pressure roller and the pressure block come into contact, the unlocking magnet can apply a magnetic attraction force to the locking pin it is close to, so that the locking pin is completely removed from the locking slot, thereby releasing the frame's restriction on the movement of the adjusting mounting bracket.

[0014] Preferably, the upper and lower side walls of the locking slot are provided with allowance rollers, the rotation axis of the allowance rollers is perpendicular to the movement direction of the locking pin, the wheel surface of the allowance rollers rolls against the upper side wall of the locking pin, and the end of the locking pin facing the bottom of the locking slot is coaxially formed with a mating cone tip.

[0015] Its effect is that during the process of the locking pin moving in and out of the locking slot, the wheel surface of the allowance roller and the locking pin are in rolling contact, thereby reducing the moving resistance of the locking pin.

[0016] Preferably, a protective cover is rotatably mounted on the adjusting mounting bracket. The protective cover is coaxially sleeved outside the conveyor roller. The cross-section of the protective cover is a large arc. A clearance opening is provided on one side of the protective cover. When the conveyor roller contacts the glass door, the clearance opening is located above the conveyor roller. When the laser emitting head is located above the conveyor roller, the rotation angle of the drive gear is 180°.

[0017] Its effect is that when the conveyor roller comes into contact with the glass door, the protective cover will not obstruct the rolling contact between the conveyor roller and the glass door. At this time, the protective cover forms a barrier to protect the side of the conveyor roller, preventing damage from the small fragments generated by the laser cutting action on the nearby glass door.

[0018] Preferably, a drive gear is coaxially fixed to the end of the protective cover, the conveying roller passes coaxially through the drive gear, a drive rack is fixedly connected to the frame, the length direction of the drive rack is parallel to the moving direction of the adjusting mounting frame, and the drive rack transmits torque to the drive gear.

[0019] Its effect is that during the adjustment of the mounting frame moving relative to the frame, the drive gear and drive rack also mesh and drive, and the drive gear drives the protective cover to rotate, so that the protective cover can protect the upper side of the conveyor roller at this time.

[0020] Preferably, the protective cover and the drive gear are detachably connected, and a fixed-axis frustum is fixedly connected to the side of the drive gear facing the protective cover. A fixed-hole protrusion is fixedly connected to one side of the fixed-axis frustum. The inner wall of the protective cover contacts the side wall of the fixed-axis frustum, and the fixed-hole protrusion contacts the side edge of the protective cover facing the opening.

[0021] Its effect is that the fixed-axis frustum is used to position the axial position of the protective cover, and the fixed-hole protrusion is used to determine the position of the clearance opening to position the circumferential position of the protective cover. Together, they position the protective cover and the drive gear to each other.

[0022] Preferably, the protective cover includes two molecular shells that are hinged to each other, the length direction of the hinge axis is parallel to the axis of the protective cover, the hinge axis of the two molecular shells is located on the side of the axis of the protective cover away from the fixed hole protrusion, and the drive gear is provided with a fixing member for keeping the molecular shells fixed.

[0023] Its effect is that when the two molecular shells rotate relative to their own hinge axis, the opening degree of the clearance opening is adjusted and changed, so that the fixed-axis frustum can cross the clearance opening and enter the protective cover, which facilitates the installation or removal of the protective cover and the drive gear.

[0024] Preferably, the fixing member is a backstop block, the backstop block is movably connected to the drive gear, there are two backstop blocks, each backstop block corresponds to a molecular shell, and the backstop block and the molecular shell are in contact on the side away from the fixed axis frustum.

[0025] Preferably, the drive gear has an installation groove on the side facing the protective cover, the anti-reverse block is located in the installation groove, an automatic spring is connected between the anti-reverse block and the bottom of the installation groove, the anti-reverse block has an installation wedge surface, the installation wedge surface is located on the side of the anti-reverse block away from the molecular shell, and in the natural state, the installation wedge surface is located at the opening of the installation groove.

[0026] Its effect is as follows: During the installation of the protective cover, the molecular shell is brought closer to the fixed-axis frustum, and the inner wall of the end of the molecular shell abuts against the installation wedge surface, generating a resisting force on the installation wedge surface. Under the decomposition of the wedge surface, the anti-reverse block is pushed towards the bottom of the installation groove, the automatic spring retracts, and after the anti-reverse block is fully inserted into the installation groove, the molecular shell crosses the installation groove and contacts the fixed-axis frustum. Then the anti-reverse block pops out from the installation groove and contacts the outer wall of the molecular shell, thus completing the installation of the molecular shell. When disassembling the protective cover, the anti-reverse block must be manually pressed first to make it fully retract into the installation groove before the molecular shell can be separated from the fixed-axis frustum, thus completing the disassembly.

[0027] By adopting the above technical solution, the beneficial effects of the present invention are as follows: This invention adjusts the mounting bracket, protective cover, and adjustment mechanism so that the conveyor roller approaching the laser emitter descends to maintain a distance from the glass door, while the protective cover rotates to the top of the conveyor roller to protect it. After the laser emitter leaves, both the conveyor roller and the protective cover return to their original positions, and the conveyor roller continues to support the glass door.

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figures 1-9The present invention discloses a glass door laser processing device, comprising a frame 1, on which a laser emitting head 11 and a moving mechanism 2 are mounted. The frame 1 is also equipped with a glass processing conveying mechanism, a positioning mechanism, and an electrical control box (the operating table and dust collection box are separate and independent), as well as a 1064 wavelength red laser and a diamond grinding wheel for notch and edge trimming. The device mainly functions to perform three types of laser drilling, notch cutting, and notch and edge trimming, and is specifically used for glass door processing, such as installing door hinges, handles, and locks on glass doors.

[0040] like Figure 1 As shown, the glass conveying mechanism includes multiple conveying rollers 12 rotatably mounted on the frame 1. These rollers 12 are arranged horizontally, with all axes parallel to each other, and are used to place a glass door 5. The glass door 5 includes a glass door panel and a glass door frame mounted on the glass door panel. When the glass door 5 to be processed is placed on the frame 1, the lower side panel of the glass door 5 simultaneously contacts the upper sidewalls of the multiple conveying rollers 12, applying a certain pushing force to the glass door 5 placed on the conveying rollers 12. The glass door 5 can then slide along the arrangement direction of the conveying rollers 12. A laser emitting head 11 is located above the glass door 5, and a moving mechanism 2 controls the two-dimensional horizontal movement of the laser emitting head 11.

[0041] like Figure 1 As shown, the moving mechanism 2 includes a main moving frame 21 and a secondary moving frame 22. The main moving frame 21 is slidably connected to the frame 1, and the secondary moving frame 22 is slidably connected to the main moving frame 21. The moving direction of the main moving frame 21 is parallel to the arrangement direction of the multiple conveying rollers 12, while the moving direction of the secondary moving frame 22 is parallel to the length direction of the conveying rollers 12. An electric slide table for driving the main moving frame 21 is provided inside the frame 1, and a motor screw for driving the secondary moving frame 22 is provided inside the main moving frame 21. The laser emitting head 11 is fixedly mounted on the secondary moving frame 22 and emits a laser beam downwards. Under the combined action of the main moving frame 21 and the secondary moving frame 22, the movement range of the laser emitting head 11 can cover the entire glass door 5.

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, multiple adjustable mounting brackets 13 are slidably mounted on the frame 1. The sliding direction of the adjustable mounting brackets 13 is vertical. The number of adjustable mounting brackets 13 is the same as the number of conveyor rollers 12. Each conveyor roller 12 is rotatably connected to an adjustable mounting bracket 13, so that each conveyor roller 12 can rotate on its own and move vertically through the adjustable mounting bracket 13. An adjustment mechanism 3 is also provided on the frame 1. The adjustment mechanism 3 is used to control the downward movement of the adjustable mounting bracket 13 where the conveyor roller 12 is located below the laser emitter head 11, so that a gap is formed between the roller surface of this conveyor roller 12 and the glass door 5. The adjustment mechanism 3 includes a support spring 31, a force-bearing block 32, and a pressure roller 33. One end of the support spring 31 is connected to the frame 1, and the other end is connected to the adjustable mounting bracket 13. The extension and contraction direction of the support spring 31 is vertical. The support spring 31 always applies an upward supporting force to the adjustable mounting bracket 13, that is, all conveyor rollers 12 that are not approached by the laser emitter head 11 are at the upper end of their vertical stroke.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, the pressure block 32 and the adjusting mounting frame 13 are fixedly connected. In the axial projection along the conveying roller 12, the shape of the pressure block 32 is approximately an isosceles trapezoid. The pressure roller 33 is rotatably mounted on the main moving frame 21. The axis of the pressure roller 33 is horizontal and perpendicular to the arrangement direction of the multiple conveying rollers 12. During the movement of the main moving frame 21, the wheel surface of the pressure roller 33 can roll over the pressure block 32. The side of the pressure block 32 contacts the pressure roller 33 first. The contact force of the pressure roller 33 on the pressure block 32 has a vertically downward component, thereby causing the pressure block 32 and the adjusting mounting frame 13 connected to the pressure block 32 to move downward. In this embodiment, the number of pressure blocks 32 connected to a single adjusting mounting frame 13 is two, and the number of pressure rollers 33 is two. The two pressure blocks 32 and the two pressure rollers 33 are located at opposite ends of the conveying roller 12, respectively.

[0044] like Figure 3 and Figure 4As shown, a locking pin 14 is slidably mounted on the frame 1. The sliding direction of the locking pin 14 is horizontal and perpendicular to the sliding direction of the adjusting mounting bracket 13. Each adjusting mounting bracket 13 corresponds to two locking pins 14. Each adjusting mounting bracket 13 has two locking slots 131 for the locking pins 14 to be inserted. A self-locking spring 141 is connected between one end of the locking pin 14 and the frame 1. The self-locking spring 141 has a small elastic modulus. In its natural state, the end of the locking pin 14 away from the self-locking spring 141 is inserted into the locking slot 131. At this time, even if downward pressure is applied to the adjusting mounting bracket 13, the adjusting mounting bracket 13 cannot move downward, thereby improving the stability of the conveying roller 12 that is not near the laser emitter 11. The locking pin 14 is made of magnetic metal; in this embodiment, iron is used. An unlocking magnet 331 is fixedly connected to the main moving frame 21 near the pressure roller 33. In this embodiment, the mounting shaft of the pressure roller 33 on the main moving frame 21 is a fixed shaft, and the unlocking magnet 331 is fixedly embedded at the center of the end of its fixed shaft. Before the pressure roller 33 and the pressure block 32 come into contact, the unlocking magnet 331 can apply a magnetic attraction force to the locking pin 14 it is close to, so that the locking pin 14 is completely removed from the locking slot 131, thereby releasing the movement restriction of the frame 1 on the adjusting mounting frame 13. In order to improve the smoothness of the locking pin 14 when it is removed from the locking slot 131, the upper and lower side walls of the locking slot 131 are provided with allowance rollers 132. The rotation axis of the allowance rollers 132 is perpendicular to the movement direction of the locking pin 14, and the wheel surface edge of the allowance rollers 132 rolls against the upper and lower side walls of the locking pin 14. When the pressure roller 33 leaves the pressure block 32, the adjusting mounting bracket 13 moves upward and resets. At the same time, the locking pin 14, which has almost lost its magnetic attraction, re-enters the locking slot 131. In order to improve the smoothness of the locking pin 14 re-entering the locking slot 131, the end of the locking pin 14 facing the bottom of the slot 131 is coaxially formed with a mating cone tip 142.

[0045] like Figure 2 , Figure 4 and Figure 5As shown, a protective cover 4 is also rotatably mounted on the adjusting mounting bracket 13. The protective cover 4 is coaxially sleeved outside the conveyor roller 12. The cross-section of the protective cover 4 is an arc with an arc angle of 257°. That is, one side of the protective cover 4 has a clearance opening 40 along its own length, and the inner wall of the protective cover 4 does not contact the surface of the conveyor roller 12. When the conveyor roller 12 and the glass door 5 come into contact, the clearance opening 40 is located above the conveyor roller 12, so the protective cover 4 will not obstruct the rolling contact between the conveyor roller 12 and the glass door 5. At this time, the protective cover 4 forms a protective barrier on the side of the conveyor roller 12 to prevent damage to the nearby glass door 5 from small fragments generated by laser cutting. There is a gap of 5mm to 8mm between the inner wall of the protective cover 4 and the side wall of the conveying roller 12; the rotation axis of the protective cover 4 coincides with the axis of the conveying roller 12; both ends of the protective cover 4 are coaxially fixed with drive gears 42; the drive gears 42 are installed in the adjusting mounting bracket 13; a through hole for the conveying roller 12 to pass through is coaxially opened in the middle of the drive gears 42; and a bearing (not shown in the figure) is provided between the drive gears 42 and the conveying roller 12.

[0046] like Figure 4 , Figure 5 and Figure 6 As shown, a relay gear 43 is rotatably mounted inside the adjusting mounting frame 13. The axis of the relay gear 43 is parallel to the axis of the drive gear 42, and the relay gear 43 meshes with the drive gear 42. The pitch circle diameter of the relay gear 43 is twice that of the drive gear 42. A drive rack 44 is fixedly connected to the frame 1. The length direction of the drive rack 44 is parallel to the moving direction of the adjusting mounting frame 13, and the drive rack 44 meshes with the relay gear 43. During the upward or downward movement of the adjusting mounting frame 13, the drive rack 44 transmits torque to the drive gear 42 through the relay gear 43, causing the drive gear 42 and the protective cover 4 to rotate. When the adjusting mounting frame 13 moves to the lower end of its stroke, the protective cover 4 rotates 180°, at which point the opening 40 is positioned below the conveyor roller 12. The protective cover 4 provides protection for the conveyor roller 12 on both sides and above, thereby reducing damage caused by cutting operations from above.

[0047] like Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the protective cover 4 suffers considerable damage during the laser cutting process. To facilitate replacement of the protective cover 4, the protective cover 4 and the drive gear 42 are detachably connected. The protective cover 4 includes two mutually hinged molecular shells 41, with the length direction of their hinge axis parallel to the axis of the protective cover 4. A fixed-axis frustum 45 is fixedly connected to the side of the drive gear 42 facing the protective cover 4. A fixed-hole protrusion 451 is fixedly connected to one side of the fixed-axis frustum 45. The inner wall of the protective cover 4 and the side wall of the fixed-axis frustum 45 are in close contact. The fixed-hole protrusion 451 and the side edge of the protective cover 4 facing the relief opening 40 are in contact. Thus, the fixed-axis frustum 45 and the fixed-hole protrusion 451 jointly position the protective cover 4 axially and circumferentially. The two molecular shells 41 are angled by a hinge shaft, which facilitates the installation and removal of the protective cover 4 relative to the fixed-axis frustum 45. When the protective cover 4 is installed on the fixed-axis frustum 45, the hinge shaft between the two molecular shells 41 is located on the side of the axis of the protective cover 4 away from the fixed-hole protrusion 451.

[0048] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the drive gear 42 is provided with a fixing member for keeping the two molecular shells 41 fixed. The fixing member is a backstop block 46. There are two backstop blocks 46 and the backstop blocks 46 are movably connected to the drive gear 42. Each backstop block 46 corresponds to one molecular shell 41. When the inner side of the molecular shell 41 contacts the fixed-axis frustum 45, the backstop block 46 contacts the side of the molecular shell 41 away from the fixed-axis frustum 45. At this time, the backstop block 46 forms a limiting abutment on the molecular shell 41, and the molecular shell 41 cannot move away from the fixed-axis frustum 45. Two mounting grooves 421 are provided on the side of the drive gear 42 facing the protective cover 4. A single anti-reverse block 46 is located in one mounting groove 421 and can slide along the depth direction of the mounting groove 421. An automatic spring 461 is connected between the anti-reverse block 46 and the bottom of the mounting groove 421. The anti-reverse block 46 is provided with a mounting wedge surface 462, which is located on the side of the anti-reverse block 46 away from the molecular shell 41. In the natural state, the mounting wedge surface 462 is located at the opening of the mounting groove 421. During the installation of the protective cover 4, the molecular shell 4 is pushed... As the molecular shell 41 approaches the fixed-axis frustum 45, the inner wall of its end abuts against the mounting wedge surface 462, generating a resisting force on the mounting wedge surface 462. Under the decomposition of the wedge surface, the anti-reverse block 46 is pushed towards the bottom of the mounting groove 421, the automatic spring 461 contracts, and after the anti-reverse block 46 is fully inserted into the mounting groove 421, the molecular shell 41 crosses the mounting groove 421 and contacts the fixed-axis frustum 45. Subsequently, the anti-reverse block 46 pops out from the mounting groove 421 and contacts the outer wall of the molecular shell 41, thus completing the installation of the molecular shell 41. When disassembling the protective cover 4, the anti-reverse block 46 must first be manually pressed until it is fully retracted into the mounting groove 421 before the molecular shell 41 can be separated from the fixed-axis frustum 45, completing the disassembly.

[0049] The implementation principle of the laser processing device for glass doors of the present invention is as follows: During laser cutting, the glass door 5 is placed on the conveying roller 12, and the main moving frame 21 moves along the arrangement direction of multiple conveying rollers 12, so that the laser emitting head 11 reaches above different conveying rollers 12. When the pressure roller 33 rolls over the pressure block 32, its corresponding adjusting mounting frame 13 descends, and the conveying roller 12 below the laser emitting head 11 separates from the glass door 5. At the same time, the protective cover 4 on its outer side rotates and forms protection for the conveying roller 12 above it. Thus, the high-temperature molten material generated by laser cutting will hardly affect the conveying roller 12 below it, thereby protecting the conveying roller 12.
