Description

Technical Field

[0001] The present invention relates to a laser cutting device, in particular to a laser cutting device for optical glass processing applied in the field of laser cutting technology. Background Art

[0002] Optical lens glass is a special kind of glass used to manufacture optical lenses and lenses, such as optical instruments, telescopes, microscopes, photographic lenses and other equipment. Optical glass is often cut into circles and is mainly cut and formed using laser cutting equipment.

[0003] The specification of Chinese patent CN117964227A discloses "An optical lens glass laser cutting device", which automatically receives, limits and automatically takes out the cut lens glass through a receiving and picking mechanism. The cut lens glass does not fall directly, causing certain damage to the lens glass, affecting the quality of the lens glass and the subsequent use effect. The specification of Chinese patent CN116789356A discloses "An optical glass cutting and processing machine", which uses a fixing part to fix the glass sheet and support the bottom to ensure that the glass sheet is in a stable state during the laser cutting process, thereby achieving high-quality cutting and forming.

[0004] In order to ensure the complete cutting of the optical glass, the optical glass is in an overhead state so that the cutting laser can completely pass through the optical glass. In this state, the cut optical glass slices are at risk of falling and bumping. The bottom of the optical glass slices needs to be supported by a supporting structure, but the supporting structure is easily affected by the cutting laser, causing damage to the supporting structure and affecting the normal use of the laser cutting device. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the receiving structure is easily affected by the cutting laser, causing damage to the receiving structure and affecting the normal use of the laser cutting device.

[0006] To solve the above problems, the present invention provides a laser cutting device for optical glass processing, comprising a processing table, wherein both ends of the top of the processing table are fixedly connected to longitudinal track mechanisms, a transverse track mechanism is fixedly connected between the movable ends of the two longitudinal track mechanisms, a glass plate to be processed is placed in the middle of the processing table, a cutting body module is fixedly connected to the movable end of the transverse track mechanism, one end of the cutting body module is fixedly connected to a dual-output shaft motor, and a laser cutting unit is fixedly connected to the output end of the dual-output shaft motor near the glass plate to be processed;

[0007] The bottom of the glass plate to be processed is movably connected to a bottom supporting bracket, the two ends of the bottom supporting bracket are fixedly connected to the bottom of the transverse track mechanism, and the top of the bottom supporting bracket is slidably connected to a lifting platform, the lifting platform is slidably supported by the lower surface of the glass plate to be processed, and the top of the lifting platform is slidably connected to a telescopic plate, the telescopic plate is vertically crossed with the bottom supporting bracket, and the end of the telescopic plate close to the laser cutting unit is fixedly connected to a C-shaped piece, both ends of the C-shaped piece are fixedly connected to top contact terminals, and the two top contact terminals are vertically corresponding to the laser cutting unit;

[0008] The cutting body module is parallel to the bottom bracket, and the cutting body module is slidingly connected to the upper magnetic module at one end away from the dual-output shaft motor. A linkage push-pull arm is hinged between the upper magnetic module and the other output end of the dual-output shaft motor. The telescopic plate is fixedly connected to the lower magnetic module at one end away from the C-shaped piece, and the upper magnetic module is magnetically corresponding to the lower magnetic module.

[0009] In the above-mentioned laser cutting device for optical glass processing, the telescopic plate slides telescopically so that the top contact end automatically avoids the laser beam of the laser cutting unit, effectively reducing the damage to the top contact end caused by the laser.

[0010] As a further improvement of the present application, the four top corners of the processing table are fixedly connected with placement piles, and the four placement piles correspond to the four corners of the glass plate to be processed, so that the glass plate to be processed on the processing table is fixedly placed in the air, effectively improving the placement stability of the glass plate to be processed.

[0011] As a further improvement of the present application, a guide groove is fixedly connected to the outside of one end of the lifting platform close to the C-shaped piece. The bottom of the guide groove is arranged in an inclined surface, and the bottom end of the guide groove is slidably connected to the processing table. The optical glass slices cut by laser slide onto the processing table through the guide groove, effectively reducing the damage to the optical glass slices caused by direct falling.

[0012] As a further improvement of the present application, an extension rib is fixedly connected to one end of the top contact end close to the guide groove, and the extension rib extends into the guide groove. The extension rib provides support for the optical glass slice, thereby facilitating the transfer of the optical glass slice into the guide groove.

[0013] As another improvement of the present application, a recessed groove is provided on the inclined end surface of the guide chute, a receiving plate is hinged on the top of the recessed groove, and the extending ribs correspond horizontally to the receiving plate. The guide chute utilizes the receiving plate to transfer and receive the optical glass slices in a horizontal state, and the optical glass slices are not easily dropped directly onto the inclined surface of the guide chute, thereby effectively reducing the occurrence of bumps and damage to the optical glass slices.

[0014] As another improved supplement to the present application, an elastic sheet is fixedly connected to the hinged end of the receiving plate and the recessed groove. The elastic sheet and the receiving plate are fixed in a V-shaped state, and the elastic sheet is fixedly connected to the inside of the recessed groove. The elastic sheet is made of an elastic plastic sheet. The elastic force of the elastic sheet is utilized to realize automatic upward flipping of the receiving plate, and when the optical glass slice is transferred to the receiving plate, the receiving plate is pressed to flip downward, so that the optical glass slice can slide naturally along the guide groove.

[0015] As another improved supplement to the present application, a magnetic end piece is fixedly connected to one end of the bottom of the receiving plate near the extension rib, and the magnetic end piece corresponds magnetically to the extension rib. The magnetic end piece is made of a permanent magnet material, and the extension rib is made of a stainless steel material. The magnetic connection between the magnetic end piece and the extension rib is utilized to effectively improve the connection effect between the receiving plate and the extension rib, thereby facilitating the smooth passage of the optical glass slice through the connection portion between the receiving plate and the extension rib, and facilitating the complete transfer of the optical glass slice to the surface of the receiving plate.

[0016] To sum up, the present invention moves the bottom bracket following the horizontal track mechanism, and then the upper magnetic module corresponds to the lower magnetic module through magnetic attraction, so that the lifting platform moves accurately to the cutting position of the glass plate to be processed, and the top contact terminals at both ends of the C-shaped piece provide support for the optical glass slices cut by the laser, so that the optical glass slices are not easy to fall directly. In the process of the dual-output shaft motor driving the laser cutting unit to perform laser cutting, the dual-output shaft motor synchronously drives the upper magnetic module to slide, and similarly, the upper magnetic module corresponds to the lower magnetic module through magnetic attraction, so that the telescopic plate can slide on the lifting platform, and then the top contact terminals at both ends of the C-shaped piece can automatically avoid the laser beam performing circular motion, effectively reducing the damage caused by the laser beam to the top contact terminals, and effectively improving the normal use effect of the laser cutting device.

[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figures 1 to 3 The figure shows a laser cutting device for optical glass processing, comprising a processing table 1, both ends of the top of the processing table 1 are fixedly connected to longitudinal track mechanisms 101, a transverse track mechanism 102 is fixedly connected between the movable ends of the two longitudinal track mechanisms 101, a glass plate 103 to be processed is placed in the middle of the processing table 1, the movable end of the transverse track mechanism 102 is fixedly connected to a cutting body module 104, one end of the cutting body module 104 is fixedly connected to a dual-output shaft motor 105, the dual-output shaft motor 105 refers to a motor with two output shafts, which is a mature technical means in this field, the dual-output shaft motor 105 is fixedly connected to a laser cutting unit 106 near the output end of the glass plate 103 to be processed, and the four corners of the top of the processing table 1 are fixedly connected to placement piles 107, and the four placement piles 107 correspond to the four corners of the glass plate 103 to be processed, so that the glass plate 103 to be processed on the processing table 1 is fixedly placed overhead, thereby effectively improving the placement stability of the glass plate 103 to be processed;

[0031] When performing laser cutting processing on the glass plate 103 to be processed, the glass plate 103 to be processed is fixed overhead on the top of the processing table 1 by four mounting piles 107, and the cutting body module 104 locates the cutting position on the glass plate 103 to be processed through the longitudinal track mechanism 101 and the transverse track mechanism 102. The dual-output shaft motor 105 drives the laser cutting unit 106 to cut the glass plate 103 to be processed to obtain a circular optical glass slice.

[0032] Figures 3 to 7 As shown, the bottom of the glass plate 103 to be processed is movably connected to the bottom support 2, the two ends of the bottom support 2 are fixedly connected to the bottom of the transverse track mechanism 102, and the top of the bottom support 2 is slidably connected to the lifting platform 201, the lifting platform 201 is slidably supported by the lower surface of the glass plate 103 to be processed, and the top of the lifting platform 201 is slidably connected to the telescopic plate 202, the telescopic plate 202 is arranged perpendicularly to the bottom support 2, and the end of the telescopic plate 202 close to the laser cutting unit 106 is fixedly connected to the C-shaped piece 203, and both ends of the C-shaped piece 203 are fixed. A top contact terminal 204 is fixedly connected, and the two top contact terminals 204 are vertically corresponding to the laser cutting unit 106. The cutting body module 104 is parallel to the bottom bracket 2, and the end of the cutting body module 104 away from the dual-output shaft motor 105 is slidably connected to the upper magnetic module 205. A linkage push-pull arm 206 is hinged between the upper magnetic module 205 and the other output end of the dual-output shaft motor 105. The end of the telescopic plate 202 away from the C-shaped piece 203 is fixedly connected to the lower magnetic module 207, and the upper magnetic module 205 and the lower magnetic module 207 are magnetically corresponding;

[0033] When adjusting the position of the transverse track mechanism 102, the bottom bracket 2 moves along with the transverse track mechanism 102 to achieve transverse alignment between the bottom bracket 2 and the position to be cut. When the cutting body module 104 is adjusted on the transverse track mechanism 102, the upper magnetic module 205 and the lower magnetic module 207 are magnetically attracted to each other, attracting the lifting platform 201 to slide on the bottom bracket 2, so that the lifting platform 201 is accurately moved to the position to be cut of the glass plate 103 to be processed. The top contact terminals 204 at both ends of the C-shaped piece 203 provide support for the optical glass slice cut by the laser, and the optical glass slice is not easily dropped directly.

[0034] In the process of the dual-output shaft motor 105 driving the laser cutting unit 106 to perform laser cutting, the shaft rotation motion of the dual-output shaft motor 105 is converted into a push-pull motion that drives the upper magnetic module 205 to slide through the linked push-pull arm 206. The upper magnetic module 205 slides on the cutting body module 104. Similarly, through the magnetic correspondence between the upper magnetic module 205 and the lower magnetic module 207, the telescopic plate 202 is enabled to slide on the lifting platform 201, and then the top contact ends 204 at both ends of the C-shaped piece 203 automatically avoid the laser beam emitted by the circular motion laser cutting unit 106, effectively reducing the damage caused by the laser beam to the top contact end 204.

[0035] Second implementation method:

[0036] Compared with the first embodiment, a guide groove 3 for guiding the optical glass slice to slide is mainly added. The specific new structure is as follows, and the remaining structures are consistent with the first embodiment.

[0037] Figure 4 and Figure 8 As shown, the lifting platform 201 is fixedly connected to the outside of one end near the C-shaped piece 203 with a guide chute 3. The bottom of the guide chute 3 is set in an inclined surface, and the bottom end of the guide chute 3 is slidably connected to the processing table 1. The optical glass slice cut by the laser slides onto the processing table 1 through the guide chute 3, effectively reducing the damage to the optical glass slice caused by direct falling. The end of the top contact end 204 near the guide chute 3 is fixedly connected to an extension rib 301. The extension rib 301 extends into the guide chute 3, providing support for the optical glass slice through the extension rib 301, facilitating the transfer of the optical glass slice into the guide chute 3.

[0038] After completing the laser cutting of an optical glass slice, the cutting body module 104 moves to the next cutting position. At this time, the cut optical glass slice has not yet been separated from the glass plate 103 to be processed. The guide chute 3 replaces the lifting platform 201 and moves to the bottom of the optical glass slice. During this handover process, the extension rib 301 on the top contact end 204 continues to provide support for the optical glass slice, enabling the optical glass slice to enter the guide chute 3, and the optical glass slice slides along the guide chute 3 onto the processing table 1, effectively reducing the damage to the optical glass slice caused by direct falling.

[0039] Figure 8 and Figure 9The top of the recessed groove 302 is hinged with a receiving plate 303, and the extension rib 301 corresponds to the receiving plate 303 in a horizontal manner. The guide groove 3 uses the receiving plate 303 to transfer and receive the optical glass slice in a horizontal state, so that the optical glass slice is not easily dropped directly onto the inclined surface of the guide groove 3, thereby effectively reducing the damage to the optical glass slice caused by collision. The receiving plate 303 and the hinged end of the recessed groove 302 are fixedly connected with an elastic sheet 304. The elastic sheet 304 is fixed to the receiving plate 303 in a V-shaped state, and the elastic sheet 304 is fixedly connected to the inside of the recessed groove 302. The elastic sheet 304 is made of an elastic plastic sheet. Those skilled in the art may preferably use polyurethane plastic. 4 realizes the automatic upward flipping of the receiving plate 303, and when the optical glass slice is transferred to the receiving plate 303, the receiving plate 303 is pressed to flip downward, so that the optical glass slice slides naturally along the guide groove 3. The bottom of the receiving plate 303 is fixedly connected to one end of the extension rib 301, which is close to the extension rib 301. The magnetic end grain 305 corresponds to the extension rib 301 by magnetic attraction. The magnetic end grain 305 is made of permanent magnet material, and the extension rib 301 is made of stainless steel. The magnetic connection between the magnetic end grain 305 and the extension rib 301 effectively improves the connection effect between the receiving plate 303 and the extension rib, so that the optical glass slice can pass smoothly through the connection part between the receiving plate 303 and the extension rib, and the optical glass slice can be completely transferred to the surface of the receiving plate 303.

[0040] The support plate 303 is connected to the support plate 301 by the magnetic attraction end 305, so that the optical glass slice can be easily moved along the guide groove 303.

[0041] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
