Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1, as Figures 1 to 9 As shown, a fully automatic glue dispensing machine for mobile phone screen production includes an automatic mobile device 1 for automatic glue dispensing and an automatic glue dispensing device 2.

A loading and unloading mechanism 6 for automatically loading and unloading the mobile phone is fixedly installed on the automatic mobile device 1, and the loading and unloading mechanisms 6 are distributed on opposite sides of the rotating mechanism 5. The automatic moving device 1 comprises a motor 501 fixedly mounted on the bottom of the automatic moving device 1, the output shaft of the motor 501 passes through the automatic moving device 1 and is fixedly connected to a rotating seat 502, four connecting rods 503 are fixedly connected to the arc profile of the rotating seat 502, and the four connecting rods 503 are distributed in a ring array, one end of the connecting rod 503 is provided with a groove, and a magnetic connecting shaft 504 is inserted in the groove, one end of the magnetic connecting shaft 504 is fixedly connected to a positioning mold 505, and a magnetic block 506 is fixedly connected to the groove of the connecting rod 503, and the magnetic pole of the magnetic block 506 is opposite to that of the magnetic connecting shaft 504.

[0041] The loading and unloading mechanism 6 includes two electric push rods 601 fixedly installed on the automatic moving device 1, and the two electric push rods 601 are respectively located on the opposite sides of the rotating seat 502, and the tops of the output shafts of the two electric push rods 601 are respectively fixedly connected with a unloading platform 602 for automatic unloading and a loading platform 603 for automatic loading. A through groove is provided on the top of the unloading platform 602 close to the positioning mold 505, and a rotating block 604 is rotatably connected to the inner wall of the through groove through a torsion spring. The unloading platform 602 and the loading platform 603 are respectively provided with corresponding external transportation equipment on the side away from the positioning mold 505.

[0042] The positioning mechanism 4 includes a positioning seat 401 fixedly connected to the top of the moving platform 3, an air storage chamber 406 is provided at the bottom of the positioning seat 401, and a piston in the air storage chamber 406 is connected to a piston plate 402, a magnetic disk 403 is embedded in the center of the piston plate 402, an electromagnet 404 is embedded in the center of the positioning mold 505, and the magnetic pole of the electromagnet 404 is opposite to the magnetic pole of the magnetic disk 403, a first trigger switch 405 is installed at one end of the electromagnet 404 located in the groove of the connecting rod 503, and the first trigger switch 405 is electrically connected to the electromagnet 404, a connecting block 409 is symmetrically installed on the outer wall of the positioning seat 401, an air guide chamber 408 connected to the air storage chamber 406 is provided in the connecting block 409, and the top of the connecting block 409 is movable The plug is connected with a positioning block 410 for positioning and clamping. The initial state of the electromagnet 404 is the closed state. The motor 501 in the rotating mechanism 5 drives the rotating seat 502 to rotate, so that the four positioning molds 505 located outside the rotating seat 502 are placed on the positioning mechanism 4 in sequence for positioning. The output shaft of the motor 501 rotates, thereby driving the rotating seat 502 and the four positioning molds 505 connected to the rotating seat 502 to move, thereby achieving the effect of continuously transporting the mobile phone to the specified position. The setting of the connecting rod 503 and the magnetic connecting shaft 504 can achieve the effect of quick disassembly and assembly, and convenient loading and unloading, and on the other hand, the magnetic attraction generated by the setting of the opposite magnetic poles can ensure that the rotating seat 5 02 During rotation, the positioning mold 505 always maintains a stable connection. When the external conveying device conveys the positioning mold 505 loaded with the mobile phone to slide onto the loading platform 603, the corresponding electric push rod 601 will control the loading platform 603 to connect the positioning mold 505 with the connecting rod 503 through the magnetic connection shaft 504, so that the positioning mold 505 is stably connected to the vacant position of the rotating seat 502. After the positioning mold 505 enters the specified position after the dispensing is completed, the unloading platform 602 will move to the bottom of the positioning mold 505 through the control of the corresponding electric push rod 601. At this time, the rotating block 604 will be pressed down and rotated into the through groove. Then, when the rotating block 604 is separated from the lower surface of the positioning mold 505, the torsion spring will push the rotating block 604 is reset, and under the movement of the output shaft of the electric push rod 601, the positioning mold 505 is pulled out of the rotating seat 502 and enters the external transportation equipment to leave, finally achieving the effect of automatic loading and unloading. By setting the initial state of the electromagnet 404 to the closed state, the transportation of the positioning mold 505 can be facilitated. In the process of the loading platform 603 plugging the positioning mold 505 into the rotating seat 502, the first trigger switch 405 will be triggered for the first time when the magnetic connection shaft 504 enters and abuts against the magnetic block 506. At this time, the electromagnet 404 is started to generate magnetic force. When the positioning mold 505 moves to the positioning seat 401, the magnetic disk 403 embedded in the piston plate 402 is set with the opposite magnetic pole of the electromagnet 404 on the positioning mold 505.When the rotating seat 502 rotates the positioning mold 505 loaded with the mobile phone to the specified position on the positioning seat 401, the magnetic attraction generated between the disk 403 and the electromagnet 404 will drive the piston plate 402 to rise, thereby squeezing the air in the air storage chamber 406 through the air guide chamber 408 to push the positioning block 410 to rise in the connecting block 409. Finally, multiple positioning blocks 410 will gradually calibrate and position the outer wall of the positioning mold 505 in a clamping manner to ensure the stability of the positioning mold 505 on the positioning seat 401. Then, after the dispensing is completed, , the moving platform 3 pushes the positioning seat 401 to reset, so that the magnetic connection shaft 504 is re-inserted into the connecting rod 503. At this time, the first trigger switch 405 is triggered again and the electromagnet 404 is turned off. Finally, under the rotation of the rotating seat 502, the positioning mold 505 enters the working position of the unloading platform 602 and is removed from the rotating seat 502 by the unloading platform 602 and transported away. In the above process, the positioning mold 505 is in a non-magnetic state at the unloading platform 602 and the loading platform 603, which is convenient for the transportation of the positioning mold 505. ,

[0043] A method for dispensing glue using a fully automatic dispensing machine for producing mobile phone screens, comprising the following steps:

[0044] S1. The mobile phone to be glued is placed in the positioning mold 505 and transported to the loading platform 603 by an external transportation device;

[0045] S2, the output shaft of the corresponding electric push rod 601 drives the loading platform 603 to transport the positioning mold 505 through the plugging of the connecting rod 503 and the magnetic connecting shaft 504, so that the positioning mold 505 is connected to the rotating seat 502;

[0046] S3, the output shaft of the motor 501 drives the rotating seat 502 and the positioning mold 505 to rotate in a circle, so that the positioning mold 505 is placed on the top of the positioning seat 401;

[0047] S4, the positioning mechanism 4 automatically positions and calibrates the positioning mold 505, and starts the automatic moving device 1;

[0048] S5, the automatic mobile device 1 drives the positioning mold 505 to move to the designated dispensing position, and cooperates with the automatic dispensing device 2 to automatically dispense glue on the mobile phone on the positioning mold 505;

[0049] S6, after the dispensing is completed, the automatic moving device 1 is reset, and the positioning mold 505 after the dispensing is completed is connected to the rotating seat 502 again by plugging the magnetic connecting shaft 504 and the connecting rod 503;

[0050] S7, the motor 501 controls the rotating seat 502 and the positioning mold 505 to rotate to the unloading platform 602 again;

[0051] S8. The output shaft of the corresponding electric push rod 601 controls the unloading platform 602 to move to the bottom of the positioning mold 505 after the dispensing is completed, and pushes the positioning mold 505 into the corresponding external transportation equipment for transportation.

[0052] Embodiment 2

[0053] As a supplement to Example 1, Figure 8 and Fig. 9 As shown, a plurality of first springs 407 are fixedly connected between the top of the inner wall of the air storage chamber 406 and the adjacent surface of the piston plate 402, and the plurality of first springs 407 are evenly arranged, a plurality of second springs 411 are fixedly connected between the bottom of the positioning block 410 and the bottom of the inner wall of the air guide chamber 408, and a second trigger switch 412 for transmitting a start signal is fixedly installed on the top of the inner wall of the air storage chamber 406. By evenly arranging the plurality of first springs 407, the reset action of the auxiliary piston plate 402 after compression can be achieved, and the stability of the piston plate 402 when the piston moves in the air storage chamber 406 can be improved. By arranging the plurality of second springs 411, the positioning block 410 can be limited to prevent the compressed air from directly pushing the positioning block 410 out of the air guide chamber 408, causing the problem of being unable to position. At the same time, the retraction of the second spring 411 will also pull the positioning block 410 to reset. By installing the second trigger switch 412 on the top of the inner wall of the air storage chamber 406, it can be achieved that after the piston plate 402 is attracted by the magnetic force of the electromagnet 404 on the magnetic disk 403 and rises to the specified position, it will abut and trigger the second trigger switch 412, thereby starting the power mechanism on the automatic moving device 1 and driving the moving platform 3 to move. This setting can improve the automation effect between devices. After the specified action is completed in the previous step, the operation of the next step can be carried out stably, thereby improving the full-automatic effect of the dispensing machine. At the same time, the piston plate 402 cannot smoothly abut and trigger the second trigger switch 412, which can also be used to detect whether there is a jamming problem between the positioning block 410 and the connecting block 409, resulting in excessive air compression resistance.

[0054] Embodiment 3

[0055] Further improvements are made on the basis of the first embodiment, such as Figure 1 and Figure 4As shown, the tops of the multiple positioning blocks 410 are arranged on one side close to the positioning mold 505 as an inclined plane, the inner upper surface of the unloading platform 602 is arranged on an inclined plane, and the highest point of the inclined plane is close to the rotating block 604. By setting the tops of the positioning blocks 410 close to the positioning mold 505 as an inclined plane, it is convenient for the electromagnet 404 to calibrate and position the positioning mold 505 that fails to fully match the positioning seat 401 by gathering and clamping during the rising process, so as to prevent the electromagnet 404 from lifting one side of the positioning mold 505. By setting the inner upper surface of the unloading platform 602 as an inclined plane, and the highest point of the inclined plane is close to the rotating block 604, it can be achieved that when the unloading platform 602 peels the positioning mold 505 from the rotating seat 502, the inclined plane cooperates with the extension action of the electric push rod 601 to accelerate the positioning mold 505 to slide down into the external conveying equipment and leave.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
