Technical Field

[0001] The utility model relates to the technical field of glass tube laser cutting equipment, in particular to a large-volume glass tube positioning and breaking mechanism. Background Art

[0002] Traditional wheel cutters produce a large amount of glass dust when cutting glass tubes, which requires water to rinse and cool, causing environmental pollution. The material utilization rate is only about 70%, and the waste cannot be directly recycled and reproduced because the wheel cutter will wear out during the cutting process, and the worn-out material will contaminate the glass tube, thereby changing the properties of the glass.

[0003] To this end, in existing technology, when cutting large quantities of glass tubes, a positioning mechanism is typically used to position the tubes. A laser head then reciprocates to perform a non-contact initial modification and cutting of the tubes. A glass cutter is then used to manually cut the laser-cut areas. However, this manual cutting method is inefficient and has a low degree of automation. Utility Model Content

It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the scope of protection of the present invention.

[0020] See also Figure 1 、 Figure 2 and Figure 3 A large-volume glass tube positioning and breaking mechanism is installed on the platform 10 of the glass tube pushing platform and can advance and retreat and rise and fall relative to the output end 111 of the conveying surface 11 of the platform 10. It includes two sets of advance and retreat drive units 21, two sets of rise and fall drive units 22, and a two-way stop plate 23. The two sets of advance and retreat drive units 21 are arranged opposite to each other on the platform 10. Each advance and retreat drive unit 21 is correspondingly installed on an outer wall of the platform 10 near the output end 111. It includes an advance and retreat drive cylinder 211 and a displacement seat 212. The advance and retreat drive cylinder 211 is installed on the outer wall of the platform 10. , the setting direction of the driving end of the forward and backward driving cylinder 211 is consistent with the conveying direction of the conveying surface 11; the front end of the displacement seat 212 is connected to the driving end of the forward and backward driving cylinder 211, and the rear end of the displacement seat 212 passes through the outside of the table body 10, so that the driving end of the forward and backward driving cylinder 211 can be extended and retracted, driving the displacement seat 212 to advance and retreat relative to the table body 10. Specifically, the driving end of the forward and backward driving cylinder 211 is extended, and the middle and rear end of the displacement seat 212 pass through the outside of the table body 10, and when the driving end of the forward and backward driving cylinder 211 is retracted, only the rear end of the displacement seat 212 passes through the outside of the table body 10;

[0021] Two sets of lifting drive units 22 are arranged opposite to each other outside the platform 10, and each lifting drive unit 22 is correspondingly installed on the rear end outer wall of a displacement seat 212, and the driving end of the lifting drive unit 22 is arranged upward;

[0022] The two-way abutment plate 23 is arranged outside the platform 10, and the two-way abutment plate 23 is connected to the driving ends of the two sets of lifting drive units 22, so that the driving ends of the lifting drive units 22 can be extended and retracted to drive the two-way abutment plate 23 to rise and fall. When the driving ends of the lifting drive units 22 are retracted, the bottom surface of the two-way abutment plate 23 is flush with the conveying surface 11 of the platform 10.

[0023] Further, see Figure 4 In this embodiment, a first guide rail assembly 24 is provided between the displacement seat 212 and the outer wall of the table body 10. The first guide rail assembly 24 includes a displacement guide rail 241 installed on the outer wall of the table body 10 and a first slider 242 slidably provided on the displacement guide rail 241. The setting direction of the displacement guide rail 241 is consistent with the conveying direction of the conveying surface 11. The first slider 242 is connected to the displacement seat 212 to improve the extension and retraction of the driving end of the forward and backward driving cylinder 211, thereby driving the stability of the displacement seat 212 when it moves forward and backward relative to the table body 10.

[0024] Further, see Figure 5 In this embodiment, the inner wall of the displacement seat 212 is recessed with a notch groove 201 in the area corresponding to the first guide rail assembly 24, and is connected to the first slider 242 and accommodates the displacement guide rail 241 through the notch groove 201.

[0025] Furthermore, in this embodiment, a second guide rail assembly 25 is provided on the inner wall of the rear end of the displacement seat 212. The second guide rail assembly 25 includes a guide plate 251 connected to the bottom surface of the two-way abutment plate 23, a longitudinal guide rail 252 arranged on the outer wall of the guide plate 251, and a second slider 253 slidably arranged on the longitudinal guide rail 252. The second slider 253 is connected to the inner wall of the displacement seat 212 to improve the extension and retraction of the driving end of the lifting drive unit 22, thereby driving the stability of the two-way abutment plate 23 when it is lifted or lowered.

[0026] Furthermore, in this embodiment, the table 10 is provided with a glass tube positioning and rotating mechanism 30 on the output end 111 of its conveying surface 11, which is used to press and position the glass tube and drive the glass tube to rotate when the laser head reciprocates to cut the glass tube, so as to increase the range of laser cutting.

[0027] Furthermore, in this embodiment, a pushing mechanism 40 is installed on the platform 10 to push the glass tube along the conveying surface 11 toward the output end 111, thereby realizing automatic pushing of the glass tube.

[0028] Furthermore, in this embodiment, the platform 10 is provided with a laser cutting mechanism 50 outside the output end 111 of the conveying surface 11 thereof, so that the laser cutting mechanism 50 cuts the glass tube along the edge of the output end 111 .

[0029] Furthermore, in this embodiment, the platform 10 is provided with a plurality of feed sensors 12 on both sides of the output end 111 of its conveying surface 11. When the feed sensor 12 senses that the glass tube is pushed to a preset position, it transmits a signal to the pushing mechanism 40, the glass tube positioning and rotating mechanism 30, the large-batch glass tube positioning and breaking mechanism, and the laser cutting mechanism 50, so that they operate according to the preset program.

[0030] As can be understood, the method for using the large-volume glass tube positioning and breaking mechanism of the present invention includes the following steps: first, manually laying a large number of glass tubes flat on the conveying surface 11 of the glass tube pushing table; second, starting the glass tube pushing table, and the pushing mechanism 40 automatically pushes the glass tubes to the processing position. At the same time, the driving end of the forward and backward driving cylinder 211 extends, and the middle and rear ends of the displacement seat 212 pass out of the table body 10, while the driving end of the lifting drive unit 22 remains retracted. When the glass tubes reach the processing position, the ends of the glass tubes pass through the edge of the output end 111 and abut against the front end of the two-way abutment plate 23, thereby positioning the glass tubes; third, The glass tube positioning and rotating mechanism 30 presses and positions the glass tube, allowing the laser head of the laser cutting mechanism 50 to reciprocate along the edge of the output end 111 to cut the glass tube. During this reciprocating process, the glass tube positioning and rotating mechanism 30 drives the glass tube to rotate, thereby increasing the range of laser cutting. Fourthly, after laser cutting is completed, the driving end of the lifting drive unit 22 extends, and then the driving end of the forward and backward drive cylinder 211 retracts, driving the two-way support plate 23 to move above the glass tube. Finally, the driving end of the lifting drive unit 22 retracts, pressing the bottom surface of the two-way support plate 23 against the end of the cut glass tube, causing it to break under force. Fifthly, the broken finished product is transported to the outside. In this way, the pushing mechanism 40 continues to push the glass tube to the processing position to the set length, and the above steps 2 to 5 are repeated until the entire batch of glass tubes is processed.

[0031] In summary, the present invention provides a large-volume glass tube positioning and breaking mechanism, which can position the glass tube before laser cutting and automatically break the glass tube after laser cutting through the cooperation between the two sets of advance and retreat drive units 21, the two sets of lifting drive units 22 and the two-way abutment plate 23, thereby effectively improving the cutting efficiency of the glass tube.
