DETAILED DESCRIPTION

[0025] The utility model is further explained in detail below in combination with the drawings and embodiments. Same parts are indicated by same reference signs.

[0026] Figures 1-4 For the first embodiment of the utility model, a kind of laser equipment for bipolar ear synchronous cutting, including two symmetrical transmission devices 1, two transmission devices 1 are used to transmit lug, in an embodiment, the transmission direction of two transmission devices 1 is opposite, in this embodiment, two transmission devices 1 are transmitted in the same direction, first processing position 2 and second processing position 3 are formed on two transmission devices 1, and first processing position 2 and second processing position 3 are sequentially arranged along the transmission direction.

[0027] Preferably, it further includes two cutting units, two cutting units are used to cut the lug of first processing position 2 and second processing position 3 respectively, i.e. single cutting unit simultaneously cuts the lug of two first processing position 2 / second processing position 3, and cutting unit includes laser 4, optical adjustment unit 5 and beam splitter 6, the optical adjustment unit 5 is used to adjust laser reflection path, simultaneously reflects and teaches laser, to obtain more stable and suitable divergence angle laser beam, laser emitted by laser 4 enters beam splitter 6 after passing through optical adjustment unit 5, and beam splitter 6 output end is equipped with galvanometer unit 7, and galvanometer unit 7 is used to receive the laser of beam splitter 6 and reflect to first processing position 2 / second processing position 3.

[0028] Specifically, beam splitter 6 is used to split laser into two laser beams, so the number of beam splitter 6 output end is 2, therefore, the number of galvanometer unit 7 is 2 and is set to correspond to two beam splitter 6 output ends.

[0029] In use, the two transmission devices 1 respectively transmit two tabs, so that the two tabs pass through the first processing position 2 and the second processing position 3 in turn, and further, when the two tabs correspond to the first processing position 2 respectively, the laser emitted by the single laser 4 enters the beam splitter 6 after passing through the optical adjustment unit 5, and is split into two laser beams by the beam splitter 6, and the two laser beams respectively enter the two galvanometer units 7, and are reflected to the two first processing positions 2 / second processing positions 3 by the galvanometer units 7.

After the primary cutting is completed, the transmission device 1 transmits the tab to the second processing position 3, and the laser passing through the second processing position 3 performs secondary cutting on the tab.

[0030] Due to the adoption of the secondary cutting forming mode, the area of single cutting is greatly reduced, thereby greatly reducing the vibration of the tab generated in the single cutting process, thereby improving the cutting quality.

[0031] At the same time, the splitting of the laser beam by the beam splitter 6 can realize the adjustment of the energy of the two split laser beams, so as to realize the simultaneous processing and cutting of tabs of different materials on the two transmission devices 1, thereby greatly improving the production efficiency.

[0032] Specifically, the optical platform 8 is further included, the optical adjustment unit 5 includes a beam expander 9, the beam expander 9 is arranged on the optical platform 8 through a mirror holder, the laser emitted by the laser 4 enters the beam splitter 6 through the beam expander 9, and the beam expander 9 is used to expand the diameter of the laser beam and effectively reduce the divergence angle of the laser beam, so as to improve the quality of the laser beam.

[0033] Preferably, an angle is formed on the optical platform 8, and a first mounting surface 10 and a second mounting surface 11 are formed by the angle and are inclined to each other, the laser 4 is arranged corresponding to the first mounting surface 10, the beam splitter 6 is arranged corresponding to the second mounting surface 11, and the optical adjustment unit 5 further includes a plurality of reflecting mirrors 12, the reflecting mirrors 12 are also arranged on the optical platform 8 through mirror holders, and the reflecting mirrors 12 are used to reflect the laser emitted by the laser 4 to the beam splitter 6.

[0035] Preferably, the galvanometer unit 7 includes a galvanometer adapter plate 13, a galvanometer body 14 and a scanning lens 15, and the split laser of the beam splitter 6 sequentially passes through the galvanometer adapter plate 13, the galvanometer body 14 and the scanning lens 15 and is output to the first processing position 2 / second processing position 3.

[0036] Preferably, the transmission device 1 comprises a roller 16 for driving the tab transmission, and the transmission device 1 is provided with a dust removal unit 17 corresponding to the first processing position 2 and the second processing position 3.

[0037] Through the arrangement of the dust removal unit 17, the debris generated by the tab cutting can be sucked, thereby improving the processing quality of the tab.

[0038] Preferably, the dust removal unit 17 comprises a dust removal box, a passage 18 for the tab to pass through is arranged on the dust removal box, a window 19 for the laser to pass through is arranged on one side of the dust removal box corresponding to the passage 18, and a wind blade 20 is arranged on the dust removal box corresponding to the first processing position 2.

[0039] Preferably, the transmission device 1 comprises a negative suction plate 21, and the dust removal box and the negative suction plate 21 are arranged along the tab transmission direction.

[0040] Through the arrangement of the negative suction plate 21, the stability of the tab during the tab cutting process can be further improved, and the vibration of the tab caused by the suction of the dust removal box can be reduced.

[0041] Preferably, a supporting roller 22 is further arranged, the upper end of the passage 18 is an entry end of the tab, and the supporting roller 22 is arranged corresponding to the entry end. Through the arrangement of the supporting roller 22, the stability of the tab when entering the entry end can be improved, so as to reduce the winding and bending that may occur at the entry end.

In this embodiment, the number of beam splitters 6 is set to be multiple, and a transmission structure is arranged to drive the multiple beam splitters 6 to move, so that the beam splitter 6 with a suitable splitting ratio is used according to the required laser energy of different materials. The transmission structure is any two-dimensional or three-dimensional movement mode in the prior art, which is not limited here.

[0044] In another way, the beam splitter 6 is a laser beam splitting polarizer.

Specifically, a terminal connected with the laser beam splitting polarizer can be arranged, and the terminal is used to control the laser beam splitting polarizer in real time to adjust the splitting ratio.

[0045] Specifically, the operator sets the initial light splitting ratio and laser power according to the material to be cut before cutting, and continuously monitors the cutting depth, consistency and cutting effect during the cutting process through the tab cutting sensor, which is a prior art and will not be described in detail here. When the tab cutting sensor detects that the current light splitting ratio cannot meet the cutting requirements, the terminal receives the signal and adjusts the rotation angle of the half-wave plate in the laser beam splitter polarizing mirror, thereby adjusting the light splitting ratio of the laser beam splitter polarizing mirror, so as to optimize the light splitting ratio under the condition that the total laser power remains unchanged, so as to achieve the predetermined cutting effect.

[0046] Preferably, when the above adjustment still cannot meet the cutting effect, the terminal controls the laser 4 to increase the output power and correspondingly adjusts the light splitting ratio, thereby achieving the purpose of secondary adjustment, so that the sensor can feedback the cutting effect in real time during the whole cutting process, so as to optimize the light splitting ratio and the laser power, thereby realizing the demand for efficient and accurate machining.

Any technical solution falling within the scope of the present application is within the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, some improvements and decorations without departing from the principles of the present application are also considered to be within the protection scope of the present application.
