Description

Technical Field

[0001] The invention relates to the technical field of glass tube cutting equipment, and in particular to an automated laser cutting line for mass production of glass tubes. Background Art

[0002] In social production and life, glass tubes are widely used. They can be used in various fields such as electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electricity, environmental protection, etc. In the existing glass tube processing process, it is usually necessary to cut the longer glass tube into a certain length according to the specified requirements. In the prior art, people usually use glass cutters to manually cut glass tubes. When cutting glass tubes, the glass tubes are usually broken due to excessive cutting pressure of the glass cutter, which not only wastes materials, but also may cause hand injuries to operators. The manual cutting method is not only inefficient, but also the glass tubes need to be manually broken after manual cutting. The process is complicated and the degree of automation is low, resulting in low work efficiency. Summary of the invention

[0032] Combined with reference Figure 4 The pushing mechanism 12 is installed on the top surface of the top plate of the platform 11, and includes a fixing frame 121 set up at the output end 102, two belt wheel seats 122 arranged opposite to each other at the pushing end 101, a belt transmission component 123 arranged between the fixing frame 121 and the two belt wheel seats 122, and a pushing plate 124 arranged at the pushing end 101 and capable of sliding along the pushing surface 111. The belt transmission component 123 is used to drive the pushing plate 124 to slide along the pushing surface 111, so that a plurality of glass tubes are laid flat on the pushing surface 111. The pushing plate 124, driven by the belt transmission component 123, pushes the front end of the glass tube and pushes the rear end of the glass tube out of the edge of the output end 102.

The driving end of the linear driving module 131 is connected to the lateral displacement seat 132, and the driving end of the lifting driving module 133 is connected to the pressing plate 134, so that the lifting driving module 133 drives the pressing plate 134 to extend relative to the pushing surface 111, and the pressing plate 134 presses the glass tube to position, the linear driving module 131 drives the lateral displacement seat 132 to move laterally, and the lifting driving module 133 and the pressing plate 134 move synchronously with the lateral displacement seat 132 to drive the glass tube to rotate;

[0034] Combined with reference Figure 5The positioning and breaking mechanism 14 is installed on the side plates at both sides of the platform 11, and includes an advance and retreat driving unit 141 and an advance and retreat displacement seat 142, which are arranged one after the other at the surface of one side plate adjacent to the output end 102, a lifting driving unit 143 arranged on each advance and retreat displacement seat 142, and a two-way abutment plate 144 arranged outside the platform 11 and capable of advancing and retreating and lifting relative to the edge of the output end 102. The driving end of the advance and retreat driving unit 141 is connected to the advance and retreat displacement seat 142, and the driving end of the lifting driving unit 143 is connected to the two-way abutment plate 144. After the front end of the glass tube is pushed out of the body of the seat with a preset length, before laser cutting is performed, the front end of the two-way abutment plate 144 is used to abut the rear end of the glass tube under the cooperation of the advance and retreat driving unit 141 and the lifting driving unit 143, and after laser cutting, the rear end of the glass tube is pressed by the bottom surface of the two-way abutment plate 144 to break the glass tube;

[0035] Combined with reference Figure 8 The lane dividing mechanism 15 is installed on the bottom surface of the top plate of the platform body 11, and includes a slope adjustment module 151 and a lane dividing ramp 152 arranged one after the other at the bottom surface of the top plate adjacent to the output end 102. The front end of the lane dividing ramp 152 is hinged to the bottom surface of the top plate through a hinge plate 153, and the rear end of the lane dividing ramp 152 passes out of the platform body 11 and is in a slope shape relative to the top plate; the driving end of the slope adjustment module 151 can abut against the bottom surface of the lane dividing ramp 152, so that the driving end of the slope adjustment module 151 can be extended and retracted to adjust the abutting position of the lane dividing ramp 152, thereby adjusting the swing angle of the lane dividing ramp 152 relative to the top plate;

[0036] Combined with reference Fig. 9 The laser cutting mechanism 20 is mounted outside the output end 102 of the platform 11, and includes a frame 21, a lateral reciprocating drive mechanism 22 disposed at the front end of the frame 21, and a laser cutting module 23 disposed on the lateral reciprocating drive mechanism 22 and the frame 21, so that the lateral reciprocating drive mechanism 22 drives the laser cutting head of the laser cutting module 23 to move back and forth laterally along the edge of the output end 102 above the platform 11, thereby laser cutting the glass tube;

[0037] The material receiving assembly 30 is arranged outside the output end 102 of the table body 11, and includes a waste collection box 31 placed under the dividing ramp 152, a feeding channel 32 installed behind the waste collection box 31, and a material receiving box 33 placed behind the feeding channel 32. During the initial cutting, the driving end of the slope adjustment module 151 retracts to drive the dividing ramp 152 to swing down, and a waste discharge space is formed between the dividing ramp 152 and the feeding channel 32. The waste generated by the initial cutting falls from the waste discharge space into the waste collection box 31. During the subsequent cutting, the driving end of the slope adjustment module 151 extends out to drive the dividing ramp 152 to connect with the feeding channel 32, and the cut glass tubes fall into the material receiving box 33 along the dividing ramp 152 and the feeding channel 32 in sequence.

[0038] It can be understood that the method for using a large-volume automated laser cutting line for glass tubes of the present invention comprises the following steps: the first step is to manually lay a large number of glass tubes flat on the pushing surface 111 of the platform 11; the second step is to start the positioning and pushing platform 10, and the pushing mechanism 12 automatically pushes the glass tubes to the processing position of the output end 102. At the same time, under the cooperation of the advance and retreat drive unit 141 and the lifting drive unit 143, when the glass tube arrives at the processing position, the rear end of the two-way abutment plate 144 abuts the front end of the glass tube to position the glass tube; the third step is to use the positioning and rotating mechanism 13 to press and position the glass tube, and the laser cutting head of the laser cutting module 23 cuts the glass tube along the edge of the output end 102. After cutting, the positioning and rotating mechanism 13 drives the glass tube to move forward and backward. Rotate, the laser cutting head of the laser cutting module 23 reciprocates to cut again, so that three rotations and cutting are preferably completed; the fourth step, after the laser cutting is completed, under the cooperation of the advance and retreat drive unit 141 and the lifting drive unit 143, the bottom surface of the two-way plate 144 is pressed against the cut glass tube to break it under force; the fifth step, if it is the first cutting, the waste generated by it is retracted through the driving end of the slope adjustment module 151, driving the lane ramp 152 to swing down, and falling from the waste discharge space into the waste collection box 31, if it is a finished product cut later, it is extended through the driving end of the slope adjustment module 151, driving the lane ramp 152 to connect with the feeding channel 32, and falling into the receiving box 33 along the lane ramp 152 and the feeding channel 32 in turn. In this way, the pushing mechanism 12 continues to push the glass tube to the processing position to the set length, repeating the above second to fifth steps until the whole batch of glass tubes are processed, the operation can be ended, and the next round of manual feeding can be started. Among them, the glass tube cut by the present invention is preferably a capillary hollow glass tube. By rotating the glass tube 360°, it is ensured that the product is cut with cracks by the laser beam, and then the positioning and breaking mechanism 14 is used to break the cracks. The product will be broken along the cracks. The broken product is the finished material, which slides into the material receiving box 33 along the feeding channel 32.

[0039] In addition, the lengths of the glass tubes manually fed are roughly the same. When the pushing mechanism 12 first pushes the glass tubes to the processing position at the output end 102, the lengths of the glass tubes passing through the edge of the output end 102 may be uneven. Therefore, the initial cutting is mainly to adjust the lengths of the glass tubes to be consistent. The waste from the initial cutting is collected in the waste collection box 31.

[0040] Furthermore, in this embodiment, the fixing frame 121 is provided with two supporting plates 1211 arranged opposite to each other on the two platform edges 112 and a mounting plate 1212 connected to the tops of the two supporting plates 1211 and parallel to the pushing surface 111; a transmission shaft 1213 is rotatably provided between the two supporting plates 1211, and a motor 1214 for driving the transmission shaft 1213 to rotate is installed outside one of the supporting plates 1211; a tube passing space for the glass tube to pass through is reserved between the transmission shaft 1213 and the pushing surface 111, and the transmission shaft 1213 is provided to the glass tube to pass through. The belt transmission assembly 123 is arranged between the driving shaft 1213 and the two pulley seats 122; a slide rail 1121 parallel to the belt transmission assembly 123 is installed on each platform side 112, and a connecting slider 1122 is slidably provided on each slide rail 1121. The connecting slider 1122 connects the belt transmission assembly 123 on the same side with the side of the pushing plate 124. The power supply machine 1214 drives the transmission shaft 1213 to rotate, and the belt transmission assembly 123 drives the pushing plate 124 to move along the pushing surface 111.

[0041] Furthermore, in the present embodiment, the linear drive module 131 is arranged on the top surface of the mounting plate 1212; the lateral displacement seat 132 is provided with a connecting plate 1321 connected to the driving end of the linear drive module 131 and a seat plate 1322 connected to the rear end of the connecting plate 1321 and perpendicular to the pushing surface 111; the lifting drive module 133 is arranged on the rear end surface of the seat plate 1322, and the driving end of the lifting drive module 133 is perpendicular to the pushing surface 111; the pressing plate 134 is parallel to and has the same width or is wider than the pushing surface 111, and a flexible pad layer 1341 is provided at the bottom of the pressing plate 134, and a first lifting guide assembly 135 is provided between the top of the pressing plate 134 and the rear end surface of the seat plate 1322 to improve the extension and retraction of the driving end of the lifting drive module 133 and drive the stability of the pressing plate 134 when it is lifted or lowered.

[0042] Furthermore, in the present embodiment, when the driving end of the advance and retreat drive unit 141 is retracted, the rear end of the advance and retreat displacement seat 142 extends out of the platform 11; when the driving end of the advance and retreat drive unit 141 is extended, the middle and rear ends of the advance and retreat displacement seat 142 extend out of the platform 11; each lifting drive unit 143 is correspondingly mounted on the rear end outer wall of an advance and retreat displacement seat 142, and when the driving end of the lifting drive unit 143 is retracted, the bottom surface of the two-way abutment plate 144 is flush with the conveying surface of the platform 11, so that the driving end of the advance and retreat drive unit 141 can be driven by the lifting drive unit 143. The moving end extends out, and the driving end of the lifting drive unit 143 retracts. When the glass tube arrives at the position to be processed, the rear end of the glass tube passes through the edge of the output end 102 and presses against the front end of the two-way abutment plate 144. After laser cutting, the driving end of the lifting drive unit 143 extends out, and then the driving end of the advance and retreat drive unit 141 retracts, driving the two-way abutment plate 144 to move to the top of the glass tube. Finally, the driving end of the lifting drive unit 143 retracts, and the bottom surface of the two-way abutment plate 144 presses against the rear end of the cut glass tube, causing it to break under force.

[0043] Further, in this embodiment, in combination with reference to Figure 6 , Figure 7 A retractable guide assembly 145 is provided between the retractable displacement seat 142 and the side plate surface, and a second lifting guide assembly 146 is provided between the rear end inner wall of the retractable displacement seat 142 and the two-way abutment plate 144 to improve the stability of the two-way abutment plate 144 during advancement and retraction and lifting.

[0044] Furthermore, in this embodiment, the driving end of the slope adjustment module 151 is provided with supporting shafts 1511 on both sides, so as to support the bottom surface of the lane dividing ramp 152 .

[0045] Furthermore, in this embodiment, the material receiving assembly 30 includes an output conveyor belt mechanism 34 disposed behind the feed channel 32, and the material receiving box 33 is placed on the output conveyor belt mechanism 34.

[0046] Further, in this embodiment, in combination with reference to Fig.10 , Fig.11 A large-volume automated laser cutting line for glass tubes includes a mainframe 40 and a casing 50 sealed on the mainframe 40.

The pushing end 101 of the positioning and pushing platform 10 and the discharging end of the output conveyor mechanism 34 pass through both ends of the casing 50.

[0047] In summary, the present invention is an automated laser cutting line for glass tubes in large quantities. Through the coordination among the positioning push table 10, the laser cutting mechanism 20 and the material receiving assembly 30, after manually laying the glass tubes in large quantities on the push surface 111 of the table body 11, it can automatically perform laser cutting on the glass tubes in large quantities, thereby effectively improving the glass tube cutting efficiency.
