Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically to a glass production and cutting equipment and its cutting method. Background Technology

[0002] In the field of glass processing technology, glass cutting is a key process that determines the dimensional accuracy and appearance quality of products such as building curtain walls, furniture panels, and electronic displays. Glass needs to be cut to match the size requirements of different application scenarios. The stable fixing of glass during the cutting process and the non-destructive handling after cutting directly affect the subsequent processing efficiency and the yield of finished products.

[0003] Most mainstream glass cutting equipment currently uses an electric vacuum pump-driven negative pressure adsorption structure to ensure that the glass does not shift during cutting. The suction cups adhere to the glass surface to form a stable negative pressure, thus achieving stable positioning of the glass. At the same time, it is equipped with corresponding adjustment components to control the cutting trajectory, which can basically meet the batch cutting needs in a conventional workshop.

[0004] However, in actual production and installation scenarios, existing equipment still has certain limitations: for example, in environments without a stable power supply, such as temporary processing sites and outdoor glass installation sites, negative pressure adsorption equipment that relies on electric vacuum pumps cannot work properly. If traditional mechanical clamps are used to fix the glass, the glass edges are easily damaged due to uneven distribution of clamping force.

[0005] Even under power supply conditions, after the traditional negative pressure adsorption equipment releases the adsorption, the glass often remains attached to the surface of the suction cup due to atmospheric pressure. It requires manual assistance with tools such as pry bars to remove it. If the operating force is not properly controlled during this process, it is very easy to cause the glass edges to crack and the surface to be scratched, increasing the defect rate. Therefore, it is urgent to develop a glass production cutting equipment and its cutting method to solve these practical problems. Summary of the Invention

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0043] The first embodiment is as follows:

[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A glass production cutting device includes a workbench 1, the top of the workbench 1 is provided with a support adjusting assembly, the output end of the support adjusting assembly is rotationally connected with an adjusting rod, and the output end of the adjusting rod is provided with a quick-release tool bit 3.

[0045] The device further includes a traceless negative pressure suction mechanism 2, the mechanism 2 includes a mounting frame 201 fixed to the bottom of the workbench 1, a mounting disc 202 penetrating through the workbench 1 is fixed to the inner side of the mounting frame 201 through a support rod, and a plurality of suction assemblies 203 are equidistantly arranged in the mounting disc 202.

[0046] The suction assembly 203 includes a plurality of cylinders 2031 fixed to the mounting disc 202, a suction disc 2032 penetrating through the top of the cylinder 2031, an inner opening through groove 2033 penetrating through the suction disc 2032, a micro spring 2034 fixed in the through groove 2033, a conical sealing block 2035 fixed to the bottom of the micro spring 2034 and sealing the through groove 2033, a connecting piece 2036 penetrating through the cylinder 2031 and fixed to the bottom of the conical sealing block 2035, and a cable 2037 fixed to one end of the connecting piece 2036.

[0047] A through hole is formed in the limiting plate 2038 in the installation disc 202, and one end of the cable 2037 is fixedly connected with a handle 20381 on the limiting plate 2038, and a discharging assembly 204 is further arranged in the installation disc 202;

[0048] The support adjusting assembly comprises a support 101 fixedly connected to the top of the workbench 1, a first telescopic rod 102 fixedly connected in the support 101 and extending in the vertical direction, and a second telescopic rod 103 as an adjusting rod, which is rotatably arranged outside the output end of the first telescopic rod 102 through a bearing;

[0049] The bottom end of the first telescopic rod 102 is further fixedly connected with a rubber disc 104 for abutting against the center of the glass;

[0050] A strip-shaped moving groove is formed in the limiting plate 2038 along the length direction thereof, one end of the cable 2037 extending away from the connecting piece 2036 extends into the moving groove, and the bottom of a handle 20381 in the moving groove is fixedly connected with the cable 2037, and the length of the moving groove is greater than the transverse stroke of the cable 2037 moving with the limiting plate 2038;

[0051] The discharging assembly 204 comprises a wedge-shaped abutting block 2041 fixedly connected to the top of the limiting plate 2038, and the wedge-shaped abutting block 2041 is located at the top of the end of the limiting plate 2038 extending into the installation disc 202, and a reset spring 2042 for driving the limiting plate 2038 to reset is fixedly connected between the inner side wall of the installation disc 202 and the end of the limiting plate 2038;

[0052] The abutting rod 2043 is movably arranged in the vertical direction on the top of the installation disc 202, the top end of the abutting rod 2043 is fixedly connected with an abutting disc 2044 at the same horizontal plane as the top of the installation disc 202, and the bottom end of the abutting rod 2043 is matched with the wedge-shaped surface of the abutting block 2041;

[0053] In the adsorbing assembly 203, the outer wall of the conical sealing block 2035 is tightly fitted with the inner wall of the through groove 2033, and the suction disc 2032 is made of butyronitrile rubber.

[0054] Working principle: the glass to be cut is stably placed on the suction disc 2032 on the top of the installation disc 202, the suction disc 2032 is made of butyronitrile rubber, which can adapt to the slight unevenness of the bottom surface of the glass, avoid scratching the surface of the glass by hard contact, and form an initial seal by itself by tightly fitting the glass;

[0055] The operator manually pulls the handle 20381 to drive the cable 2037 to move transversely along the strip-shaped moving groove of the limiting plate 2038, and the length of the moving groove is reserved with sufficient redundancy to ensure that the cable 2037 will not be tightly deformed when the limiting plate 2038 is subsequently pushed transversely, and the movement interference between the adsorbing assembly 203 and the discharging assembly 204 is completely avoided;

[0056] The cable 2037 pulls the conical sealing block 2035 down synchronously through the connector 2036, the conical surface of the conical sealing block 2035 is separated from the conical surface of the through groove 2033, the through groove 2033 is in communication with the suction cup 2032, and the air in the suction cup 2032 is quickly discharged along the passage;

[0057] After the handle 20381 is loosened, the micro spring 2034 returns to the natural contraction state, which can ensure the quick resetting of the conical sealing block 2035 and will not cause the operator to pull the handle with great force due to excessive elastic force;

[0058] After the conical sealing block 2035 moves up, the outer wall thereof is tightly fitted with the inner wall of the through groove 2033 to achieve reliable sealing. At this time, a stable negative pressure is formed in the suction cup 2032, and the negative pressure is uniformly distributed in the contact area of the suction cup 2032 and the glass, which avoids the glass edge collapse caused by the edge negative pressure concentration of the traditional integral suction cup and also eliminates the need for an external vacuum pump, thereby adapting to temporary processing sheds without power supply or outdoor operation scenes;

[0059] Pulling the first telescopic rod 102 in the vertical direction can drive the rubber disc 104 to precisely abut against the central area of the glass. The rubber disc 104 limits the radial deviation of the glass during cutting through flexible contact, thereby ensuring that the cutting track is consistent with the preset path.

[0060] The second telescopic rod 103 is rotated through the bearing, the included angle between the second telescopic rod 103 and the first telescopic rod 102 can be flexibly adjusted, the length of the second telescopic rod 103 is adjusted, the cutting edge of the quick-release tool head 3 is fitted with the position to be cut of the glass, the second telescopic rod 103 is pushed to move in an arc shape with the first telescopic rod 102 as the axis, and the arc-shaped cutting of the glass is completed.

[0061] When the cut glass needs to be transferred, the handle 20381 is pulled again to move the conical sealing block 2035 downward to release the negative pressure in the suction cup 2032.

[0062] The limiting plate 2038 is pushed horizontally, the wedge-shaped abutting block 2041 at the top of the limiting plate 2038 can efficiently convert the horizontal pushing force of the limiting plate 2038 into the vertical top force of the abutting rod 2043, the abutting rod 2043 moves upward along the vertical hole of the mounting disc 202 to drive the abutting disc 2044 at the top end to lift the glass, the abutting disc 2044 is flush with the top of the mounting disc 202, and does not interfere with the glass when the glass is placed, and the abutting disc 2044 prevents local deformation of the glass by increasing the contact area when the glass is lifted.

[0063] The operator can easily take down the glass, and the elastic force of the reset spring 2042 pulls the limiting plate 2038 to return to the initial position after the limiting plate 2038 is loosened, thereby ensuring that the limiting plate 2038 is reset in place.

[0064] In summary, the linkage design of the traceless negative pressure suction mechanism 2 and the blanking assembly 204 realizes the integrated operation of precise glass suction and lossless blanking, solves the core problem of glass fixation in a non-electric power scene, avoids edge damage and low efficiency caused by manual prying, and greatly improves the yield and operation continuity of glass cutting.

[0065] Second embodiment:

[0066] In the continuous operation scene of glass batch cutting, the cable 2037 needs to be moved frequently. Although the first embodiment has realized the core functions of negative pressure suction and blanking, under long-term high-frequency operation, the cable 2037 is prone to sliding friction between the surface of the cable and the edge of the mounting rack 201 due to friction with the mounting rack 201, which not only wears the surface of the cable, but also causes the operator to pull with great effort due to increased friction resistance, affecting operation efficiency. Therefore, the device also designs a limiting assembly, and the specific structure and working principle thereof are as follows.

[0067] Reference Figure 5 In the second embodiment of the present application, the mounting rack 201 is provided at the bottom with a limiting assembly 2039 for reducing wear of the cable 2037. The assembly includes a plurality of limiting rings 20391 fixed to the bottom of the mounting rack 201 at equal intervals along the extension direction of the cable 2037. The bottom of the mounting rack 201 is also provided with two sets of limiting wheels 20392 rotatably mounted through a rotating shaft, and the two sets of limiting wheels 20392 are located outside the plurality of limiting rings 20391.

[0068] The outer wall of the limiting wheel 20392 is provided with an annular limiting groove matched with the outer diameter of the cable 2037, and the material of the limiting wheel 20392 is polytetrafluoroethylene.

[0069] Working principle: On the installation path of the cable 2037, the cable passes through the plurality of limiting rings 20391 in sequence. The limiting rings 20391 can constrain the cable 2037 transversely, ensuring that the cable always moves along the preset path and avoiding entanglement and scratching with other components of the mounting rack 201.

[0070] Meanwhile, the cable 2037 is placed in the annular limiting groove of the limiting wheel 20392. When the operator pulls the handle 20381 to move the cable, the cable will drive the limiting wheel 20392 to rotate around the rotating shaft, converting the traditional sliding friction into rolling friction between the cable 2037 and the limiting wheel 20392. Combined with the polytetrafluoroethylene material of the limiting wheel 20392, the wear rate of the cable 2037 is greatly reduced.

[0071] The design of the limiting assembly 2039 realizes long-term stable work of the cable 2037, avoids equipment downtime maintenance caused by cable wear and breakage, reduces the pulling resistance of the operator, improves the comfort of continuous operation, and further enhances the practicality of the device in batch production scenarios.

[0072] Third embodiment:

[0073] In the multi-specification glass cutting scene, different hardness glass cutting tool bits 304 need to be frequently replaced. Traditional tool bits are usually fixed by screws, and tools such as wrenches are needed during disassembly. The single tool replacement is time-consuming and laborious, which not only affects the production efficiency, but also easily causes screw slipping and tool installation deviation due to improper tool operation, resulting in a decrease in glass cutting yield. Therefore, the device is also designed with a quick-release tool bit, and the specific structure and working principle are as follows:

[0074] Reference Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 In the third embodiment of the present application, the quick-release tool bit 3 includes a housing 301 fixed to the output end of the adjusting rod, a locking frame 302 movably mounted inside the housing 301 in the horizontal direction, and a contact spring 303 fixed to the side of the housing 301 away from the output end of the adjusting rod, and the end of the contact spring 303 is fixedly connected to the side of the locking frame 302 facing the housing 301. The locking frame 302 can slide in the housing 301 to compress the contact spring 303.

[0075] An adapted glass cutting tool bit 304 is inserted into the housing 301 in the vertical direction, the outer wall of the glass cutting tool bit 304 is in sliding fit with the inner wall of the housing 301, and a locking groove 305 adapted to the locking frame 302 is formed in the top of one side of the glass cutting tool bit 304. The end of the locking frame 302 close to the glass cutting tool bit 304 can be embedded in the locking groove 305 to axially limit the glass cutting tool bit 304.

[0076] Working principle: when installing the glass cutting tool bit 304, push the locking frame 302 to compress the contact spring 303 to store elastic potential energy, and insert the glass cutting tool bit 304 along the vertical slot of the housing 301. When the locking groove 305 of the glass cutting tool bit 304 is aligned with the locking frame 302, release the locking frame 302, the contact spring 303 releases the elastic potential energy, pushes the locking frame 302 to embed in the locking groove 305, and realizes the axial limitation of the tool bit.

[0077] When replacing the tool bit, only need to push the locking frame 302 away from the locking groove 305 again, and then directly pull out the old tool bit and insert the new tool bit, so that the time-consuming of single tool replacement is shortened.

[0078] At the same time, the continuous elastic force of the abutting spring 303 can keep the stable abutment of the locking frame 302 and the locking groove 305, avoid the loosening of the cutter head caused by vibration during cutting, solve the problems of low efficiency and poor yield caused by the dependence on tools and positioning deviation in traditional tool changing, and meet the cutting demand of multiple specifications of glass.

[0079] The application further provides a cutting method of the glass production cutting equipment.

[0080] S1, the glass to be cut is stably placed on the suction cup 2032 on the top of the mounting disc 202, the handle 20381 is manually pulled to drive the cable 2037 to pull the conical sealing block 2035 to move downward along the through groove 2033, so that the inside of the suction cup 2032 is communicated with the outside, and the air in the suction cup 2032 is discharged;

[0081] After the air is discharged, the handle 20381 is released, the micro spring 2034 is reset under the elastic action of itself, drives the conical sealing block 2035 to move upward and abut against the inner wall of the through groove 2033 to seal, at this time, a negative pressure environment is formed in the suction cup 2032, and the stable adsorption and fixation of the glass are realized;

[0082] S2, the support adjusting assembly is operated to control the first telescopic rod 102 to stretch and retract along the vertical direction, so that the rubber disc 104 at the bottom end thereof abuts against the center position on the top of the glass to form the positioning constraint of the glass;

[0083] Then, the second telescopic rod 103 is rotated through the bearing, and the length of the second telescopic rod 103 is adjusted, so that the glass cutting cutter head 304 on the quick-release cutter head 3 is in contact with the surface to be cut of the glass, the second telescopic rod 103 is pushed to move around the first telescopic rod 102 as the axis, and the cutting operation of the glass is completed;

[0084] S3, after the cutting of the glass is completed, the handle 20381 is pulled again, the conical sealing block 2035 is moved downward to break the sealing state of the through groove 2033, the air outside enters the suction cup 2032, and the negative pressure adsorption is released;

[0085] Then, the limiting plate 2038 is moved transversely, the wedge-shaped abutting block 2041 at the top of the limiting plate 2038 moves with the limiting plate 2038 and is in contact with the bottom end of the abutting rod 2043, converts the transverse force into a vertical thrust, pushes the abutting rod 2043 to move upward along the vertical hole of the mounting disc 202, drives the abutting disc 2044 at the top end of the abutting rod 2043 to lift the glass, and the operator can take the glass off the mounting disc 202;

[0086] S4, when the glass cutting cutter head 304 adapted to different specifications of glass needs to be replaced, the locking frame 302 is pushed away from the glass cutting cutter head 304, the locking frame 302 compresses the abutting spring 303 and moves toward the inside of the housing 301;

[0087] The old glass cutting blade 304 is pulled out of the vertical slot of the housing 301, and the new glass cutting blade 304 is inserted into the slot, the force pushing the locking frame 302 is released, the spring 303 returns to the natural state and pushes the locking frame 302 into the locking slot 305 of the new blade, completing the replacement and locking of the glass cutting blade 304.
