DETAILED DESCRIPTION

[0029] 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. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] See Figure 1 , Figure 2 and Figure 3The display screen laser cutting device provided by the embodiment of the present application comprises a work platform, a laser cutting mechanism 2, a to-be-processed position for temporarily placing a display screen to be processed, a processing position for processing the display screen, a position conversion mechanism 50 for position conversion of the display screen in the to-be-processed position and the processing position, and a turnover mechanism 51 for turning over the display screen in the to-be-processed position. The to-be-processed position and the processing position are both arranged on the work platform. In the embodiment, the to-be-processed position and the processing position are arranged, and the position conversion mechanism 50 and the turnover mechanism are matched. After cutting one side of the display screen, the position conversion mechanism 50 is used to convert the position of another display screen and the display screen with one side cut. Then, the laser cutting mechanism 2 can continue to cut the display screen, and the display screen with one side cut can be turned over by the turnover mechanism 51 during the working time of the laser cutting mechanism 2. In this way, the waiting time of the turnover mechanism and the laser cutting mechanism 2 is saved, the utilization rate of the equipment is improved, and the processing efficiency is improved. Specifically, the work platform can comprise a marble platform 10, a cross slide linear motor mechanism 11, and a marble beam 12. The marble platform 10 can provide a stable and reliable cutting table. The cross slide linear motor mechanism 11 can move the cutting platform 30 according to the requirements of laser cutting. The cutting platform 30 can be arranged in the processing position and driven by the cross slide linear motor mechanism 11. The cross slide linear motor mechanism 11 is a common driving mechanism in the cutting field, and its specific structure and working principle are not described in detail. Preferably, the to-be-processed position is provided with a positioning platform mechanism 40 for limiting the display screen. The positioning platform mechanism 40 can position the display screen by adsorption, positioning, clamping, locking, or other methods. The display screen to be processed is positioned and limited to move to ensure the accuracy of cutting. The positioning power is adsorption. The adsorption positioning platform mechanism 40 comprises an adsorption disc for placing the display screen. The adsorption disc has air holes. Negative pressure is generated by a vacuum adsorption mechanism to act on the display screen through the air holes to complete adsorption. Of course, the adsorption method can be other existing adsorption methods. The positioning method can also be other existing positioning methods such as clamping and locking.The purpose of the position conversion mechanism 50 is to convert the display screen in the to-be-processed position and the processed position. The conversion form can be that a mechanical arm is used to grab the display screen in the to-be-processed position to the processed position, and grab the display screen in the processed position to the to-be-processed position. The conversion form can also be a rotating form, that is, a rotating disc is arranged on the working platform, and the to-be-processed position and the processed position are located on opposite sides of the rotating disc. When the positions need to be converted, the positions of the to-be-processed position and the processed position can be converted by rotating the rotating disc. Of course, the rotating form is not limited to the horizontal rotating form, and can also be a rotating transfer form in the height space, which is similar to the form of a barrel drawing water. Here, the horizontal rod is improved, a rotating support shaft is arranged in the middle of the horizontal rod, and the to-be-processed position and the processed position are located at two ends of the horizontal rod. Thus, the positions of the to-be-processed position and the processed position can be converted by rotating one circle. Further, the number of the to-be-processed position and the processed position is not limited to one, and a plurality of working positions can be arranged. For example, in the rotating form of the rotating disc, the working positions can be arranged at certain angles on the rotating disc. The working positions which are the to-be-processed positions and the processed positions are planned, and then the rotating angle is selected according to the planning to obtain the processed position. The turnover mechanism 51 is a mechanism for turning over the display screen. The turnover form can be any existing turnover form, which will not be described in detail. Preferably, the turnover mechanism 51 can be provided with a displacement mechanism, that is, the turnover mechanism 51 can move along a predetermined track, so as to cooperate with the plurality of working positions to ensure that the display screen in each to-be-processed position can be turned over. In addition, the display screen in the embodiment is not necessarily a mobile phone display screen, and any display screen which needs to be cut by laser can be applied.

[0031] As an optimization scheme of the embodiment of the application, please refer to Figure 1 、 Figure 2 and Figure 3 The device further comprises a feeding mechanism 6 for feeding the display screen to be processed to the to-be-processed position. The feeding mechanism 6 comprises a conveying channel 60 for moving a tray for holding the display screen. One end of the conveying channel 60 extends to the to-be-processed position. In the embodiment, the feeding mechanism 6 can realize automatic feeding. In the prior art, manual feeding is usually used. The specific form of feeding is to move the tray through the conveying channel 60, and the tray holds the display screen to be processed. The conveying channel 60 can be a conveying belt, and the tray can be placed on the conveying belt, and then the conveying belt moves with the tray. The driving of the feeding mechanism 6 is realized by using a driving motor. The conveying belt part surrounds the driving shaft of the driving motor to realize the rotation of the conveying belt. Of course, in addition to the feeding form, other existing feeding forms are also feasible, and the embodiment does not limit the feeding form.

[0032] Further optimization of the above scheme, please refer to Figure 1 ,Figure 2 and Figure 3 The device also comprises a pick-and-place arm mechanism 52 for grabbing the display screen to be moved. The display screen to be processed on the conveying channel 60 is moved to the processing position by the pick-and-place arm mechanism 52. In this embodiment, the pick-and-place arm mechanism 52 is used to grab the display screen on the conveying channel 60 of the feeding mechanism 6 and move it to the processing position. The pick-and-place arm mechanism 52 is a conventional mechanical arm, and its function is to grab, move along a predetermined track, and then drop the display screen at a predetermined position.

[0033] As an optimization of the embodiment of the present application, please refer to Figure 1 , Figure 2 and Figure 3 The conveying channel 60 has two conveying channels, one of which is used to move the tray carrying the display screen to be processed, and the other is used to move the empty tray receiving the processed display screen. In this embodiment, since the conveying channel 60 is used to convey the tray, two conveying channels 60 can be provided, one conveying channel 60 conveying the tray carrying the display screen to be processed, and the other conveying channel 60 conveying the empty tray. In this way, when the display screen to be processed is processed, it can be moved to the empty tray, and the processed display screen can be received by the tray. The worker can take the display screen from the tray, avoiding the display screen from being dirty or damaged. In this embodiment, the processed display screen can be moved to the empty tray by the pick-and-place arm mechanism 52 described above, or by another mechanism, which is also easy to implement, and will not be described in detail here.

[0034] Further optimization of the above scheme, please refer to Figure 1 , Figure 2 and Figure 3 The device also comprises a tray collecting mechanism for collecting the tray from which the display screen to be processed is removed and collecting the tray receiving the processed display screen. In this embodiment, in order to further realize a more automated processing process, the tray collecting mechanism can also be used to collect the tray. The collected trays are divided into two categories: one is the tray that initially carries the display screen to be processed and finally becomes an empty tray, and the other is the tray that initially is an empty tray and finally receives the processed display screen. After the collection is completed, the worker can collect them in batches.

[0035] Further optimization of the above scheme, please refer to Figure 1 , Figure 2 and Figure 3The tray collecting mechanism includes a lifting platform 70 on which the tray is placed and lifted. In this embodiment, the tray collecting mechanism is in the form of a lifting platform 70 on which the tray is placed and then lifted to change the height so that the tray is stacked, and then the worker can take away the whole stack of trays, which is convenient and avoids repeated work of collecting one by one. Preferably, two sets of tray collecting mechanisms or two sets of lifting platforms 70 are provided to correspond to the two conveying channels 60, as shown in Figure 3 The two conveying channels 60 are preferably arranged side by side so that they can move synchronously and accurately. The specific form of the tray collecting mechanism is that after the display screen on the tray carrying the display screen to be processed is moved to the processing position, the empty tray can fall onto the lifting platform 70, and the lifting platform 70 receives the empty tray. When the empty tray at the other conveying channel 60 receives the processed display screen, it can also fall onto the lifting platform 70, and the lifting platform 70 receives the empty tray. Preferably, a protective fence is further provided to prevent the tray from falling off the lifting platform 70.

[0036] As an optimization scheme of this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The device further includes a discharging mechanism 8 for moving the tray on the tray collecting mechanism out. In this embodiment, when the empty trays collected in the above embodiment reach a certain number, the discharging mechanism 8 is used to move the stacked empty trays out, and the worker takes away the whole stack of trays. When the trays receiving the processed display screens in the above embodiment reach a certain number, the discharging mechanism 8 is used to move the stacked trays out. Preferably, the discharging mechanism 8 can have two sets to correspond to the discharging work at two positions. The form of discharging can be various, and the existing forms of discharging can be used, and the specific structure and working principle are not described in detail here.

[0037] As an optimization scheme of this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The device further includes a tray separating mechanism 9 for separating the stacked trays into single trays and feeding them into the conveying channel 60 one by one. In this embodiment, the tray separating mechanism 9 is used to separate the plurality of trays into single trays and feed them into the conveying channel 60 one by one, which further optimizes the automatic processing flow by saving the manual tray separating work. Specifically, the tray separating mechanism 9 includes a tray separating cylinder and a tray separating screw. The tray separating cylinder extends to hold the bottom of the tray, the tray separating screw lifts the tray, the tray separating cylinder retracts, then the tray separating screw lowers the tray, the tray separating cylinder holds the second tray below, and the tray separating action is completed. Of course, in addition to this separation method, other existing tray separating forms are also feasible, and this embodiment does not limit the tray separating form.

[0038] So far, some of the above mechanisms have been refined, and it can be seen that some places need to use lifting, so the device preferably adopts a frame with a height for assembling various components, such as the turnover mechanism 51, the material taking and placing arm mechanism 52, and the tray collecting mechanism, which are all arranged on the frame, and the feeding mechanism 6 and the discharging mechanism are also arranged on the frame, which can reasonably utilize the height space. Generally, feeding and discharging are in the same plane to facilitate feeding and discharging. In the embodiment, due to the adoption of the lifting form, the feeding mechanism 6 can be arranged on the upper layer, and the discharging mechanism 8 can be arranged on the lower layer. Thus, the entire action trajectory from feeding to discharging is a U-shaped trajectory. Compared with the existing arrangement form, on the one hand, the height space is reasonably utilized, and on the other hand, the occupied space of the equipment is saved.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3The embodiment of the present application provides a display screen laser cutting method, which comprises the following steps: S1, conveying the display screen to be processed to a processing position; S2, conveying the display screen in the processing position to a processing position for laser cutting processing, and conveying the display screen to be processed to the processing position again; S3, after one side of the display screen in the processing position is processed, using a position conversion mechanism 50 to convert the position of the display screen in the processing position and the display screen in the processing position; and S4, continuing to process the display screen in the processing position by laser cutting, and using a turnover mechanism 51 to turn over the display screen in the processing position, and waiting for processing the other side of the display screen after the position conversion. In the embodiment, the processing position and the processing position are arranged, and the position conversion mechanism 50 and the turnover mechanism are arranged, so that after one side of the display screen is cut, the position conversion mechanism 50 is used to convert the position of the display screen and the display screen with one side cut, then the laser cutting mechanism 2 can continue to cut the display screen, and the display screen with one side cut can be turned over by the turnover mechanism 51 during the working time of the laser cutting mechanism 2, so that the waiting time of the turnover mechanism and the laser cutting mechanism 2 is saved, the utilization rate of the equipment is improved, and the processing efficiency is improved. Specifically, the working platform can comprise a marble platform 10, a cross slide linear motor mechanism 11 and a marble beam 12, wherein the marble platform 10 can provide a stable and reliable cutting table, the cross slide linear motor mechanism 11 can move the cutting platform 30 according to the requirements of laser cutting, and the cutting platform 30 can be arranged in the processing position and driven by the cross slide linear motor mechanism 11 to cooperate with the laser cutting mechanism 2. The cross slide linear motor mechanism 11 is a common driving mechanism in the cutting field, and the specific structure and working principle will not be described here. Preferably, the positioning platform mechanism 40 for limiting the display screen is arranged in the processing position, for example, the display screen can be positioned by adsorption, and the display screen can be positioned and limited to move to ensure the cutting accuracy, and the adsorption positioning platform mechanism 40 comprises an adsorption disc for positioning the display screen, the adsorption disc is provided with air holes, and negative pressure is generated by a vacuum adsorption mechanism to act on the display screen to complete adsorption. Of course, the adsorption mode can also adopt other existing adsorption modes, and the positioning mode can also adopt existing clamping, locking and other positioning modes, and the embodiment is not limited.The purpose of the position conversion mechanism 50 is to convert the display screen in the to-be-processed position and the processed position. The conversion can be achieved by using a mechanical arm to grab the display screen in the to-be-processed position to the processed position, and grab the display screen in the processed position to the to-be-processed position. The conversion can also be achieved by rotating, i.e. setting a rotating disc on the working platform, and the to-be-processed position and the processed position are located on opposite sides of the rotating disc. When the position needs to be converted, the position of the two can be converted by rotating the rotating disc. Of course, the rotating form is not limited to this horizontal rotating form, but can also be a rotating transfer form in the height space, which is similar to the form of a barrel drawing water. Here, the horizontal rod is improved, the rotating support shaft is arranged in the middle of the horizontal rod, and the to-be-processed position and the processed position are located at two ends of the horizontal rod. Thus, rotating one circle can realize the position conversion of the two. Further, the number of the to-be-processed position and the processed position is not limited to one, but can also be multiple. Regardless of which rotating form is used, multiple working positions can be set, for example, the rotating disc can set working positions at certain angles, plan which working positions are to-be-processed positions and which are processed positions, and then select the rotating angle according to the settings to obtain which processed position. The turnover mechanism 51 is a mechanism for turning over the display screen. There are many forms of turnover, and existing turnover forms can be used in the embodiment. Here, the turnover mechanism 51 can be provided with a displacement mechanism, i.e. the turnover mechanism 51 can move along a predetermined trajectory to cooperate with the multiple working positions to ensure that the display screen in each to-be-processed position can be turned over. In addition, the display screen described in the embodiment is not necessarily a mobile phone display screen. Any display screen that needs to be laser cut can be applied.

[0040] As an optimization scheme of the embodiment of the application, please refer to Figure 1 、 Figure 2 and Figure 3 After the laser cutting processing of both sides of the display screen is completed, S5, the position conversion mechanism 50 is used to exchange the display screen in the processed position to the to-be-processed position, and collect the processed display screen; S6, after the collection is completed, the to-be-processed display screen is transported to the to-be-processed position again to wait for the laser cutting processing to be completed; repeat the S1 step to the S6 step until all the display screens are processed or the processing is stopped according to the demand. In the embodiment, the continuous processing of the display screen can be realized by the above-mentioned cutting method. Compared with the existing processing, a lot of unnecessary time is saved, the work efficiency is improved, and compared with the semi-automatic processing, the fully automatic processing can not only improve the efficiency but also avoid the defects caused by the semi-automatic processing.
