The design of the glue gun is often optimized according to the characteristics of the glue and the structure of the rotor to achieve the best glue dispensing effect, and the control system: the control system is the "brain" of the entire equipment, it controls the work of the glue gun according to the preset program and parameters, the control system can adjust the glue dispensing parameters according to the different models and specifications of the generator rotor to meet different production needs, and can monitor the production situation in real time through online software, etc.

[0003] After the automatic online glue dispensing equipment of the AC generator rotor is used to dispense glue to the AC generator rotor, as the use time of the rotor increases, the glue dispensed on its outer surface will gradually become brittle and fall off, which will eventually affect the service life of the equipment. The automatic online glue dispensing equipment of the AC generator rotor completes the glue dispensing operation through the glue dispensing tube on the glue dispensing gun. After a single glue dispensing is completed, the glue applied to the glue dispensing point may still be connected to the glue inside the glue dispensing tube. Later, when the AC generator rotor is rotated and the glue dispensing position is changed, the glue between the glue dispensing tube and the glue dispensing point will be pulled to form filaments and wrap them around the outer surface of the AC generator rotor, thereby affecting the final quality of the product. Therefore, it does not meet the existing needs. We propose an automatic online glue dispensing equipment for AC generator rotors. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1 to 6 An embodiment of the present invention is as follows: an automatic online glue dispensing device for an AC generator rotor, comprising a motor rotor glue dispensing machine 1, a moving platform 3 is fixedly installed on both sides of the upper end surface of the motor rotor glue dispensing machine 1, a rotor holder 4 is installed on the outer surface of the moving platform 3, an AC generator rotor 5 is fixed on the outer surface of the rotor holder 4, a primer pre-coating mechanism 2 is provided on one side of the AC generator rotor 5, the primer pre-coating mechanism 2 comprises a square storage box 201, a cotton roller 208, a primer 214, two L-shaped sealing plates 218, a rotor surface adaptive connection mechanism and a synchronization mechanism, the primer 214 is located inside the square storage box 201, the cotton roller 208 is located inside the primer 214, and the cotton roller 208 is connected to the synchronization mechanism through the rotor surface adaptive connection mechanism, and the two L-shaped sealing plates 218 can be synchronously moved outward in the process of moving the cotton roller 208 and the rotor surface adaptive connection mechanism upward through the synchronization mechanism.

[0031] The synchronization mechanism includes a stepper motor 202, the output shaft of the stepper motor 202 is connected to a square rotating shaft 203 through a coupling, the outer side of the square rotating shaft 203 is provided with an internal threaded through hole 206 located in the middle of the lower end surface of the square storage box 201, the interior of the internal threaded through hole 206 is provided with a threaded rod 204, and the external thread of the threaded rod 204 matches the internal thread of the internal threaded through hole 206; when it is necessary to pre-coat the primer 214 on the outer surface of the rotor holder 4, the position where glue is required on the AC generator rotor 5 is moved to the top of the primer pre-coating mechanism 2 through the rotor holder 4, and then the stepper motor 202 is started, and the square rotating shaft 203 connected thereto can be driven to rotate by the stepper motor 202.

[0032] A square slot 205 is provided in the middle position of the lower end surface of the threaded rod 204, and the square shaft 203 is inserted into the inside of the square slot 205. The cross-sectional shape of the inner wall of the square slot 205 is a square. The outer surface of the square shaft 203 fits with the inner wall of the square slot 205, and the square shaft 203 and the square slot 205 are slidingly connected; since the outer surface of the square shaft 203 fits with the inner wall of the square slot 205 located at the lower end surface of the threaded rod 204, when the square shaft 203 rotates, the threaded rod 204 will rotate synchronously therewith, and when the threaded rod 204 rotates, the rotating threaded rod 204 will move up and down accordingly through the internal thread transmission of the internal thread through hole 206, and the threaded rod 204 is moved upward at this time.

[0033] The rotor surface adaptive connection mechanism includes a connecting rod A213, and the lower end face of the connecting rod A213 is fixed to the middle position of the upper end face of the threaded rod 204, a cylindrical metal block 209 is provided on the outer side of the top end of the connecting rod A213, a cylindrical groove 210 is provided inside the cylindrical metal block 209, an adaptive spring 211 is provided inside the cylindrical groove 210, and the lower end face of the adaptive spring 211 is connected to a circular plate 212 fixedly sleeved on the upper side of the outer surface of the connecting rod A213, and the outer surface of the circular plate 212 is in contact with the inner wall of the cylindrical groove 210; the synchronization mechanism also includes a concave mounting frame 207 fixed to the upper end face of the cylindrical metal block 209, and a cotton roller 208 is installed inside the concave mounting frame 207; since the cotton roller 208 is located inside the primer 214, the primer 214 can be absorbed into the inside of the cotton roller 208 through its own material properties;

[0034] As the threaded rod 204 rises, the cotton roller 208 connected to it by the connecting rod A213, the cylindrical metal block 209 and the concave mounting frame 207 will move upward together. When the cotton roller 208 contacts the AC generator rotor 5, do not turn off the stepper motor 202, and continue to move the threaded rod 204 upward. Since the cotton roller 208 has already contacted the AC generator rotor 5 at this time, the cotton roller 208 will not continue to move upward at this time, and the circular plate 212 connected to the threaded rod 204 by the connecting rod A213 will move upward inside the cylindrical groove 210 and squeeze the adaptive spring 211. When the circular plate 212 moves to the middle position inside the cylindrical groove 210, turn off the stepper motor 202, and then drive the AC generator rotor 5 to rotate through the rotor holder 4. When the AC generator rotor 5 in contact with the cotton roller 208 rotates, a layer of primer 2 will be applied to the outer surface of the AC generator rotor 5 at the position where glue needs to be dispensed. 14. After the primer 214 is applied, the cotton roller 208 is moved downward by the stepper motor 202 to re-enter the interior of the primer 214 to absorb the primer 214, and then the AC generator rotor 5 is glued. After the glue dispensing of the AC generator rotor 5 is completed, a layer of primer 214 is applied to the outer surface of the AC generator rotor 5 through the above scheme. The primer 214 applied before the glue dispensing can enhance the adhesion between the glue and the surface of the AC generator rotor 5. The layer of primer 214 applied after the glue dispensing can connect the glue applied to the outer surface of the AC generator rotor 5 into a whole, thereby further increasing the adhesion of the glue and isolating it from the outside world to prevent it from becoming brittle due to the loss of internal moisture. The above technical scheme can ensure that the glue can be firmly attached to the AC generator rotor 5 and is not easy to become brittle or fall off due to the passage of time.

[0035] If the location on the outer surface of the alternator rotor 5 where glue is to be dispensed is uneven, when the cotton roller 208 moves to the concave part, the reaction force of the squeezed adaptive spring 211 can push the cotton roller 208 upward to enter the inside of the concave part, and complete the coating operation on the concave part. If it moves to the convex part, the cotton roller 208 will be pushed downward and squeeze the adaptive spring 211. Through this rotor surface adaptive connection mechanism, the cotton roller 208 can adapt to the shape of the outer surface of the alternator rotor 5.

[0036] A guide rod 215 is fixedly provided on both sides of the lower end surface of the concave mounting frame 207. The guide rod 215 vertically penetrates the square storage box 201 and extends to the outside of the bottom of the square storage box 201. A connecting rod B216 is fixedly connected to one side of the outer surface of the guide rod 215. An inclined rod 217 is fixedly connected to one end of the connecting rod B216. Two L-shaped sealing plates 218 are respectively located above the two inclined rods 217. The surface of the L-shaped sealing plate 218 facing the inclined rod 217 and the surface of the inclined rod 217 facing the L-shaped sealing plate 218 are both inclined surfaces, and the L-shaped sealing plate 218 A sealing spring 219 is connected to one side of the outer surface; when the concave mounting frame 207 is pushed upward, the connecting rod B216 connected thereto through the guide rod 215 will move upward together, and when the connecting rod B216 moves upward, the inclined rod 217 fixed thereto will move upward synchronously, and the L-shaped sealing plate 218 can be pushed outward by the inclined rod 217 moving upward, so as to open the square storage box 201 sealed by the two L-shaped sealing plates 218, and the staff can add the primer 214 inside the square storage box 201 while it is opened;

[0037] The L-shaped sealing plate 218 will squeeze the sealing spring 219 during the outward movement. When the pre-coating treatment of the AC generator rotor 5 is completed and the cotton roller 208 is moved downward, as the cotton roller 208 descends, the reaction force of the squeezed sealing spring 219 will gradually push the L-shaped sealing plate 218 inward until the two L-shaped sealing plates 218 contact each other again, thereby sealing the square storage box 201. By sealing the square storage box 201, foreign matter can be prevented from entering the interior of the square storage box 201 when dispensing or not using the device, thereby contaminating the primer 214 located inside the square storage box 201. The above technical solution can prevent the primer 214 from being contaminated.

[0038] An anti-drawing glue dispensing head is provided above the middle position of the two AC generator rotors 5, and the anti-drawing glue dispensing head includes a glue storage cup 7, a metal circular plate 10, a glue dispensing tube 11, a glue through hole 12, a rotating mechanism, four glue storage grooves 13, four extraction holes 17, four piston plates 14 and four extraction and pushing mechanisms. The lower end surface of the glue storage cup 7 is arc-shaped, and the arc surface at the lower end surface of the glue storage cup 7 is completely fitted with the upper end surface of the metal circular plate 10;

[0039] The glue through hole 12 is located in the middle of the lower end surface of the glue storage cup 7 and communicates with the interior of the glue storage cup 7;

[0040] The four extraction holes 17 are respectively located at the four end corners of the outer surface of the metal circular plate 10, the four glue receiving grooves 13 are respectively located at the four end corners inside the metal circular plate 10, and the four extraction holes 17 are respectively communicated with the inside of the four metal circular plates 10, the four piston plates 14 are respectively located inside the four glue receiving grooves 13, the glue receiving groove 13 located at the uppermost side of the metal circular plate 10 is communicated with the inside of the glue through hole 12 through the corresponding extraction holes 17, and the glue receiving groove 13 located at the lowermost side of the metal circular plate 10 is communicated with the inside of the glue dispensing tube 11 through the corresponding extraction holes 17;

[0041] The metal circular plate 10 can be rotated at the center position of the metal circular plate 10 by the rotating mechanism, and the corresponding piston plates 14 can be moved inside the four glue receiving grooves 13 respectively by four extraction and pushing mechanisms; the extraction and pushing mechanisms include a cylinder 16, and the piston rod of the cylinder 16 is connected to a small circular plate 19, and the outer side of the small circular plate 19 is provided with a circular groove 18 located on the outer surface of the piston plate 14;

[0042] A return spring 15 is connected to both sides of the piston plate 14 facing the cylinder 16; the inner wall diameters of the glue through hole 12, the extraction hole 17, the glue dispensing tube 11 and the circular groove 18 are the same, and the outer surface of the small circular plate 19 fits the inner wall of the circular groove 18; when the glue dispensing operation is required, the cylinder 16 closest to the glue storage cup 7 is started, and the small circular plate 19 inside the glue storage groove 13 that is connected to the inside of the glue through hole 12 can be moved downward by this cylinder 16. The outer surface of 9 fits with the inner wall of the circular groove 18 located on the outer surface of the piston plate 14. As the piston plate 14 descends, a suction force will be generated, thereby sucking the glue inside the glue storage cup 7 into the extraction hole 17 and the glue storage groove 13. When the glue content inside the glue storage groove 13 and the extraction hole 17 is just enough to complete a single dispensing operation, the cylinder 16 is closed to stop the movement of the piston plate 14, and when the piston plate 14 is pulled downward, it will squeeze the return spring 15 connected to it.

[0043] The rotating mechanism includes a metal shell 6 of the dispensing head, and a replacement motor 8 is fixedly installed on one side of the outer surface of the metal shell 6 of the dispensing head. The output shaft of the replacement motor 8 is connected to a replacement shaft 9 through a coupling, and the replacement shaft 9 horizontally passes through the center point of the metal circular plate 10; when the glue extraction is completed, the replacement motor 8 is started to drive the metal circular plate 10 to rotate. As the metal circular plate 10 rotates, the positions of the extraction holes 17 on its outer surface and the glue receiving groove 13 inside it will change accordingly. At this time, the extraction hole 17 containing glue inside is moved to the position of the dispensing tube 11, and then the cylinder 16 is started again. At this time, the small circular plate 19 is pushed outward by the cylinder 16. When the small circular plate 19 moves outward, the reaction force of the squeezed return spring 15 can synchronously push the piston plate 14 outward, thereby generating a repulsive force to push the glue receiving groove 13 and the extraction hole 17 to the glue receiving groove 13. The glue in the extraction hole 17 is pushed into the dispensing tube 11 and flows out from the dispensing tube 11. Before the glue is squeezed out, the dispensing tube 11 is moved to the corresponding dispensing position on the AC generator rotor 5 by the motor rotor dispensing machine 1. After the glue is squeezed out, the dispensing tube 11 is moved by the motor rotor dispensing machine 1 to complete the dispensing operation. When the outer surface of the piston plate 14 contacts the inner wall of the glue receiving groove 13 and cannot continue to move outward, the small circular plate 19 will leave from the inside of the circular groove 18, thereby entering the extraction hole 17, and passing through the extraction hole 17 into the dispensing tube 11, so as to squeeze out the glue remaining in the dispensing tube 11. Through the above technical solution, the glue on the outer surface of the AC generator rotor 5 can be disconnected from the connection with other mechanisms, so as to prevent the occurrence of wire drawing due to pulling the glue during the dispensing process.

[0044] When the extraction hole 17 containing glue inside is moved to the position of the glue dispensing tube 11, the extraction hole 17 without glue inside and the glue receiving groove 13 are also moved to the position corresponding to the glue through hole 12, so that the glue receiving groove 13 is connected with the inside of the glue receiving cup 7. During the glue dispensing process, the cylinder 16 corresponding to the glue receiving groove 13 is started to extract the glue inside the glue receiving cup 7.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
