Description

Technical Field

[0001] The utility model belongs to the technical field of automobile gluing, and specifically refers to an intelligent automatic gluing machine for the inner decoration cover plate of the B-pillar of an automobile door. Background Art

[0002] In the production process of the inner decoration cover plate of the automobile B-pillar, in the past, manufacturers used manual methods to apply liquid glue to the required parts on the inner decoration plate with a brush. Manual operation has problems such as uneven application, missed application, and overflowing of the boundary, resulting in low production efficiency, and thus affecting the firmness of product bonding.

[0003] Therefore, an intelligent gluing machine that can replace manual labor is needed, which can not only improve product quality and production efficiency but also save labor costs. Content of the Utility Model

[0004] In view of the above situation and to solve the above problems, the utility model proposes an intelligent automatic gluing machine for the inner decoration cover plate of the B-pillar of an automobile door. Through the cooperation of the servo transfer module and the gluing mechanism, the utility model realizes positioning and quantitative gluing, improving product quality and production efficiency.

[0005] The technical solution adopted by the utility model is as follows: An intelligent automatic gluing machine for the inner decoration cover plate of the B-pillar of an automobile door includes a lower working frame, an upper working frame, a servo transfer module, a gluing mechanism, a suction cup fixture detection mechanism, and a glue feeding and pumping mechanism. The upper working frame is arranged on the lower working frame, the servo transfer module is arranged on the upper working frame, and the servo transfer module is driven by a motor and can accurately move and position in the horizontal and height directions. The gluing mechanism is arranged on the servo transfer module and moves and positions following the servo transfer module. The suction cup fixture detection mechanism is arranged at the bottom of the upper working frame and is used to fix the inner decoration cover plate of the B-pillar. The glue feeding and pumping mechanism is arranged at the bottom of the lower working frame, and the glue feeding and pumping mechanism is communicated with the gluing mechanism. A touch screen is arranged on the side wall of the lower working frame to control the servo transfer module, the gluing mechanism, the suction cup fixture detection mechanism, and the glue feeding and pumping mechanism. Safety light curtains are symmetrically arranged on the open loading side of the upper working frame, and the signal end of the safety light curtain is connected with an alarm lamp. When a person invades the operating equipment, the safety light curtain and the alarm lamp can protect the safety of the person and make the equipment stop immediately.

[0006] Furthermore, the glue application mechanism includes a mounting block, a lower valve body, an upper valve body, an upper valve core, a flow rate adjustment handle, an upper spring, an overflow pipe, a glue application head cylinder body, a lower valve core, a lower spring, and a glue application pen tip. The mounting block is arranged on the servo transfer module. The lower valve body is arranged on the side wall of the mounting block. The upper valve body is arranged on the lower valve body. A glue hole is formed in the center of the lower valve body. The upper valve core is arranged through the center of the upper valve body. The flow rate adjustment handle is rotatably arranged at the upper end of the upper valve body. The top end of the upper valve core is threadedly connected to the center of the flow rate adjustment handle. The upper spring is connected between the upper valve core and the inner side wall of the top end of the upper valve body. When the flow rate adjustment handle rotates, the upper valve core can move up and down under the action of the thread, so as to adjust the size of the glue hole in the center of the lower valve body and realize the fine adjustment of the glue flow rate. The overflow pipe is arranged through the side wall of the lower valve body and is communicated with the center of the lower valve body. A glue inlet pipe is arranged on one side of the side wall of the lower valve body close to the overflow pipe. Glue enters the center of the lower valve body from the glue inlet pipe. The glue inlet pipe is communicated with the glue feeding pump mechanism. When the glue enters the lower valve body from the glue inlet pipe, if the glue flow rate is large, the glue will automatically flow out from the overflow pipe and flow back to the glue feeding pump mechanism again. The glue application head cylinder body is arranged at the lower end of the lower valve body. The inside of the glue application head cylinder body is hollow and both the upper and lower ends are open. The lower valve core is arranged at the bottom end of the inner cavity of the glue application head cylinder body. The lower spring is connected between the lower valve core and the glue application head cylinder body. The lower spring can press the lower valve core tightly to prevent the glue from flowing out quickly from the bottom opening of the glue application head cylinder body. Only when the pressure of the glue in the glue application head cylinder body is large, the glue can push open the lower valve core and flow out. The glue application pen tip is arranged through the bottom end of the glue application head cylinder body. The preferred material of the glue application pen tip is water-permeable coating sponge.

[0007] Furthermore, the suction cup fixture detection mechanism includes a positioning plate, a profiling vacuum suction cup, and a photoelectric detector. The positioning plate is arranged at the bottom of the upper working frame. Multiple groups of the profiling vacuum suction cups are arranged in an array on the positioning plate. The profiling vacuum suction cups are adapted to the outer shape of the B-pillar interior trim cover plate. The middle of each profiling vacuum suction cup is partitioned, so that the profiling vacuum suction cup is divided into multiple parts. The photoelectric detector is arranged in the partition of the profiling vacuum suction cup. The photoelectric detector can detect whether the B-pillar interior trim cover plate is installed on the current profiling vacuum suction cup. A negative pressure hole is arranged on the profiling vacuum suction cup, and the negative pressure hole can detect whether the B-pillar interior trim cover plate is fixed firmly.

[0008] Further, the glue feeding and pumping mechanism includes a servo motor, a metering pump, a solenoid valve, a liquid level gauge, a liquid return port, and a glue bucket. The servo motor is arranged at the bottom of the lower operation rack, the metering pump is connected to the servo motor, and the servo motor controls the flow rate of the metering pump. The solenoid valve is connected to the metering pump through a pipeline. There are two solenoid valves connected to the output end of the metering pump. One solenoid valve is used to control the flow rate of the glue delivered to the glue application mechanism to achieve large-flow adjustment of the glue, and the other solenoid valve is used to control the flow rate of the overflow glue in the overflow pipe. The glue bucket is communicated with the suction end of the metering pump through a pipeline. The liquid level gauge is arranged through the glue bucket, and the liquid return port is arranged near the liquid level gauge through the top of the glue bucket. The liquid return port is communicated with the solenoid valve that controls the flow rate of the overflow pipe.

[0009] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0010] 1. The servo transfer module can control the position of the glue application pen tip on the B-pillar interior trim cover according to the set program, and cooperate with the glue application mechanism to apply the glue to the B-pillar along the set path, making the glue application amount stable and uniform.

[0011] 2.

[0023] As shown Figure 3 in the figure, the glue application mechanism 4 includes a mounting block 9, a lower valve body 10, an upper valve body 11, an upper valve core 12, a flow rate adjustment handle 13, an upper spring 14, an overflow pipe 15, a glue application head cylinder body 16, a lower valve core 17, a lower spring 18, and a glue application pen tip 19. The mounting block 9 is arranged on the servo transfer module 3, the lower valve body 10 is arranged on the side wall of the mounting block 9, the upper valve body 11 is arranged on the lower valve body 10.

The flow rate adjustment handle 13 is rotatably arranged at the upper end of the upper valve body 11. The top end of the upper valve core 12 is threadedly connected to the center of the flow rate adjustment handle 13. The upper spring 14 is connected between the upper valve core 12 and the inner side wall of the top end of the upper valve body 11. When the flow rate adjustment handle 13 rotates, the upper valve core 12 can move up and down under the action of the thread, so as to adjust the size of the glue hole at the center of the lower valve body 10 and realize the fine adjustment of the glue flow rate. The overflow pipe 15 is arranged through the side wall of the lower valve body 10, and the overflow pipe 15 is communicated with the center of the lower valve body 10. A glue inlet pipe (not shown in the attached drawings) is provided on one side of the side wall of the lower valve body 10 close to the overflow pipe 15. Glue enters the center of the lower valve body 10 from the glue inlet pipe, and the glue inlet pipe is communicated with the glue feeding and pumping mechanism 6.

The inside of the glue application head cylinder body 16 is hollow and both the upper and lower ends are open. The lower valve core 17 is arranged at the bottom end of the inner cavity of the glue application head cylinder body 16. The lower spring 18 is connected between the lower valve core 17 and the glue application head cylinder body 16. The lower spring 18 can press the lower valve core 17 tightly to prevent the glue from flowing out quickly from the bottom opening of the glue application head cylinder body 16. Only when the pressure of the glue in the glue application head cylinder body 16 is large can the glue push open the lower valve core 17 and flow out. The glue application pen tip 19 is arranged through the bottom end of the glue application head cylinder body 16. The preferred material of the glue application pen tip 19 is water-permeable coating sponge.

[0024] As shown Figure 4 in the figure, the suction cup fixture detection mechanism 5 includes a positioning plate 20, a profiling vacuum suction cup 21, and a photoelectric detector 22. The positioning plate 20 is arranged at the bottom of the upper operation frame 2. Multiple groups of the profiling vacuum suction cups 21 are arranged in an array on the positioning plate 20. The profiling vacuum suction cups 21 are adapted to the outer shape of the B-pillar interior trim cover plate a. The middle of each profiling vacuum suction cup 21 is partitioned, so that the profiling vacuum suction cup 21 is divided into multiple parts. The photoelectric detector 22 is arranged in the partition of the profiling vacuum suction cup 21. The photoelectric detector 22 can detect whether the B-pillar interior trim cover plate a is installed on the current profiling vacuum suction cup 21. A negative pressure hole 23 is provided on the profiling vacuum suction cup 21. The negative pressure hole 23 can detect whether the B-pillar interior trim cover plate a is fixed firmly.

[0025] As shown Figure 5As shown in the figure, the glue feeding and pumping mechanism 6 includes a servo motor 24, a metering pump 25, a solenoid valve 26, a liquid level gauge 27, a liquid return port 28, and a glue bucket 29. The servo motor 24 is arranged at the bottom of the lower working frame 1. The metering pump 25 is connected to the servo motor 24. The servo motor 24 controls the flow rate of the metering pump 25. The solenoid valve 26 is connected to the metering pump 25 through a pipeline. Two solenoid valves 26 are connected to the output end of the metering pump 25. One solenoid valve 26 is used to control the flow rate of the glue transported to the glue applying mechanism 4 to achieve large-flow adjustment of the glue. The other solenoid valve 26 is used to control the flow rate of the glue overflowing in the overflow pipe 15. The glue bucket 29 is communicated with the suction end of the metering pump 25 through a pipeline. The liquid level gauge 27 is arranged through the glue bucket 29. The liquid return port 28 is arranged through the top of the glue bucket 29 near the liquid level gauge 27. The liquid return port 28 is communicated with the solenoid valve 26 that controls the flow rate of the overflow pipe 15.

[0026] During specific use, first select the glue applying program for the corresponding product through the touch screen, and then successively clamp the B-pillar interior trim cover a onto the profiling vacuum suction cup 21, and adsorb and fix the B-pillar interior trim cover a through the negative pressure hole 23. At this time, the photoelectric detector 22 detects the B-pillar interior trim cover a, and the glue applying mechanism 4 is on standby; at the same time, during the loading operation, when the safety light curtain 7 detects that a person invades the operation, the alarm lamp 8 emits a beeping sound, and all power equipment is forcibly interrupted simultaneously to prevent harm to the operating personnel.

[0027] When the operator exits the upper working frame 2 and the safety light curtain 7 does not detect personnel intrusion, all power equipment resumes the operation standby state. The operator presses the switch, and the servo transfer module 3, the glue applying mechanism 4, and the glue feeding and pumping mechanism 6 start to operate.

[0028] First, the glue feeding and pumping mechanism 6 sucks a certain amount of glue from the glue bucket 29, and then is transported to the upper glue applying mechanism 4 through the control of the solenoid valve 26. The glue flows into the center of the lower valve body 10 from the glue inlet pipe on the side wall of the lower valve body 10, and then the glue flows into the glue applying head cylinder 16. When the glue pressure in the glue applying head cylinder 16 is relatively high, the lower valve core 17 is squeezed and will move upward against the lower spring 18, causing a gap to appear between the lower valve core 17 and the bottom hole of the glue applying head cylinder 16. The glue flows out from this gap and wets the glue applying pen tip 19. The glue is applied to the B-pillar interior trim cover a through the glue applying pen tip 19. The amount of glue applied is mainly determined by the metering pump 25 controlled by the servo motor 24. The metering pump 25 can achieve large-span flow adjustment and is mainly used for rough adjustment of the glue flow rate; if the glue flow rate is relatively large, the glue will flow back from the overflow pipe 15 to the liquid return port 28 above the glue bucket 29 to achieve self-adaptive adjustment of the internal glue pressure.

[0029] When fine adjustment is needed after the rough adjustment of the glue flow rate, rotate the flow rate adjustment handle 13. Under the action of the internal thread, the upper valve core 12 will move up and down relative to the lower valve body 10. When the upper valve core 12 moves upward, the gap between the central hole of the lower valve body 10 and the upper valve core 12 increases, and the glue flow rate will continue to increase, resulting in a slight upward adjustment of the glue flow rate. When the upper valve core 12 moves downward, the gap between the central hole of the lower valve body 10 and the upper valve core 12 decreases, and the glue flow rate will decrease, resulting in a slight downward adjustment of the glue flow rate.

[0030] After the fine adjustment of the glue flow rate, observe the glue applied by the glue application pen tip 19 on the B-pillar interior trim cover a again. If there are still problems with the glue application amount, simply repeat the fine adjustment by rotating the flow rate adjustment handle 13 until the glue application amount is qualified.

[0031] Then, the servo transfer module 3 drives the glue application mechanism 4 to move along the set path and apply glue to the surface of the B-pillar interior trim cover a. After all the B-pillar interior trim covers a are coated, remove the B-pillar interior trim cover a, reload the material, and repeat the above steps.

[0032] It should be noted that although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

[0033] The above describes the present invention and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present invention. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present invention.
