Further, referring to fig. 3, in order to prevent the feeding mechanism active belt 4107 from being loosened during use and affecting the effect of the feeding mechanism 41 on the feeding of the adhesive tape 5, in the present embodiment, a feeding mechanism tension pulley 4108 configured to tension the feeding mechanism active belt 4107 is further provided at an intermediate position of the bottom of the feeding mechanism active belt 4107.
Since the rubber strip 5 is made of a rubber material and tends to be twisted during conveyance, guide mechanisms are provided upstream and downstream of the feeding mechanism 41 in the conveying direction of the rubber strip 5 in this embodiment. As shown in fig. 3, the guide mechanism in this embodiment includes a feed mechanism guide block 4102 fixed to the buffer device base 42, the feed mechanism guide block 4102 having a guide hole formed in the cross section of the adhesive tape 5, and the adhesive tape 5 can be guided through the guide hole of the feed mechanism guide block 4102 and then fed backward. Here, the feeding mechanism guide block 4102 has a simple structure, can correct the twisted rubber strip 5, is easy to install, and has a remarkable guiding effect.
The guide mechanism in this embodiment further includes limit guide blocks 4101 respectively located upstream and downstream of the feeding mechanism guide block 4102, and the two limit guide blocks 4101 are configured as shown in fig. 3 and 4, and are substantially "n" shaped, and the adhesive tape 5 can be guided and conveyed through the notch thereof to ensure the accuracy of the conveyance state of the adhesive tape 5 before and after the feeding mechanism 41. Meanwhile, two sets of feed mechanism guide rollers 4109 arranged at intervals up and down are rotatably provided upstream and downstream of the feed mechanism 41, respectively, and the adhesive tape 5 is movable between the two feed mechanism guide rollers 4109 of each set. Further, the glue stripe 5 output by the feeding mechanism guide roller 4109 enters the aforementioned buffer mechanism 43 via two feeding mechanism conveying rollers 4106 arranged up and down.
In this embodiment, in order to control the stretching ratio of the rubber strip 5 during the conveying process to achieve a good conveying effect, a detection mechanism capable of detecting the tension of the conveyed rubber strip 5 is provided downstream of at least one of the feeding mechanism 41 and the feeding mechanism 44 in the conveying direction of the rubber strip 5.
Based on the design concept of the detection mechanism, as shown in fig. 3, the detection mechanism described above is provided downstream of the feed mechanism 41 in the present embodiment, and the detection mechanism includes a guide wheel 4105 that is provided near the feed mechanism feed roller 4106 and rotatably on the buffer device base 42, and a pressure detection unit that is provided on the wheel peripheral surface of the guide wheel 4105 and can abut against the adhesive tape 5. The pressure detecting unit here is a tension sensor in the prior art, and the tension sensor is advantageous for adjusting the rotation speed of the feeding mechanism driving belt driving motor 4110 by detecting the pressure of the adhesive tape 5 on the guide wheel 4105, so as to adjust the stretching ratio of the adhesive tape 5 entering the buffer mechanism 43 from the feeding mechanism 41.
Specifically, when the tension sensor detects a large pressure indicating that the tension of the adhesive tape 5 is large, the rotational speed of the rotary motor of the feeding mechanism active belt 4107 is increased to increase the speed of the adhesive tape 5 to be fed to the buffer mechanism 43, thereby reducing the tension of the adhesive tape 5. If the pressure detected by the tension sensor is small or the pressure cannot be detected, it indicates that the tension of the rubber strip 5 is small, and at this time, the rotation speed of the driving belt driving motor 4110 of the feeding mechanism needs to be reduced, so that the speed of the rubber strip 5 conveyed to the buffer mechanism 43 is reduced, and the tension of the rubber strip 5 is increased.
The buffer mechanism 43 can buffer the adhesive tape 5 being fed in, and output the buffered adhesive tape 5 when the feeding mechanism 41 cannot convey the adhesive tape 5, so as to avoid the problem of line stop caused by material shortage, thereby being beneficial to improving the continuity of the production process. In order to reduce the stretching of the adhesive tape 5 in the buffer mechanism 43 during use, the buffer wheel set adopted in the embodiment can be close to the driven wheel set to convey the buffered adhesive tape 5.
Based on the overall design concept of the buffer mechanism 43, in this embodiment, the guide rail 4303 is installed in the height direction of the buffer device base 42, and the buffer mechanism 43 further includes a sliding seat 4301 provided on the guide rail 4303 and configured to slide in a guiding manner, and a sliding actuating device provided on the buffer device base 42 and configured to actuate the sliding seat 4301 to slide. The buffer wheel set is arranged on the sliding seat 4301, and the follower wheel set is arranged on an extension line of a sliding track of the sliding seat 4301.
In a specific configuration, as shown in fig. 5, in order to increase the amount of buffering of the rubber strip 5 and reduce the space occupation of the buffering mechanism 43, the aforementioned following wheel group includes two following wheels arranged side by side at the bottom of the guide rail 4303, wherein, for convenience of description, the following wheel arranged close to the feeding mechanism 41 is referred to as a first following wheel 4306, and the other following wheel is a second following wheel 4305. The buffer wheel group comprises a first buffer wheel 4309 positioned above the first follower wheel 4306 and a second buffer wheel 4308 positioned on top of the second follower wheel 4305. In this embodiment, the adhesive tape 5 may be spirally wound between the first buffer wheel 4309 and the first follower wheel 4306 from inside to outside, and then spirally wound between the second buffer wheel 4308 and the second follower wheel 4305 from outside to inside, so as to improve the input and output effects of the adhesive tape 5, and implement buffering and conveying of the adhesive tape 5.
It should be noted that, in the present embodiment, the number of the corresponding buffer wheels and the number of the corresponding follow-up wheels included in the buffer wheel set and the follow-up wheel set can be set according to the specific buffer requirement, but in order to ensure that the adhesive tape 5 is conveyed to the adhesive tape bonding device 3 in the best state, the number of the corresponding wheels in the buffer wheel set and the follow-up wheel set is an even number with the same amount. In addition, a plurality of guide grooves for guiding the rubber strips 5 are respectively constructed on the buffer wheel set and the follow-up wheel set, the bottoms of the rubber strips 5 are abutted against the bottoms of the guide grooves, and the two sides of each rubber strip 5 are attached to the side surfaces of the guide grooves so as to guide the rubber strips 5 in the conveying process and prevent the phenomenon of partial twisting.
In this embodiment, the number of the guide grooves on the first buffer wheel 4309 and the second buffer wheel 4308 is the same, and the number of the guide grooves is one more than that of the guide grooves on the first follower wheel 4306 and the second follower wheel 4305, so that the adhesive tape 5 is buffered in a spiral manner. The number of guide slots on the first and second buffer wheels 4309 and 4308 is nine, and the number of guide slots on the first and second follower wheels 4306 and 4305 is eight. Of course, the specific number of guide grooves on the buffer wheel and the follower wheel can be adaptively adjusted according to the specific use requirement of the equipment.
For convenience of description, the guide grooves are numbered gradually larger from inside to outside. When the adhesive tape 5 is wound, the adhesive tape 5 output from the feed mechanism conveying roller 4106 is wound around the first guide groove of the first buffer wheel 4309 and then wound around the first guide groove of the first follower wheel 4306; then, the adhesive tape 5 winds through the second guide slot of the first buffer wheel 4309 and the second guide slot of the first follower wheel 4306, and so on until the adhesive tape 5 winds through the eighth guide slot of the first follower wheel 4306 and then winds through the ninth guide slot of the first buffer wheel 4309, thereby completing the buffer storage of the adhesive tape 5 on the first buffer wheel 4309 and the first follower wheel 4306. The adhesive tape 5 output by the first buffer wheel 4309 sequentially winds through the ninth guide groove of the second buffer wheel 4308 and the eighth guide groove of the second follower wheel 4305, then winds inwards in sequence, and finally is sent out through the first guide groove of the second buffer wheel 4308.

And the sliding seat 4301 is fixedly connected to the synchronous belt 4307. When the driving motor rotates, the synchronous belt 4307 can drive the sliding seat 4301 to slide on the guide rail 4303.
In addition, limit detection units are respectively arranged at two ends of the sliding track of the sliding seat 4301 to detect the sliding seat 4301 which is moved in place, so that the sliding seat 4301 stops moving after being moved in place, and the adhesive tape 5 can be prevented from being excessively stretched due to excessive movement of the sliding seat 4301. The limit detection unit in this embodiment specifically includes an upper photoelectric switch 4302 located on the top of the guide rail 4303, and two lower photoelectric switches 4304 located on the follower wheel set. When the upper photoelectric switch 4302 detects the sliding seat 4301, it can determine that the buffer wheel group moves up to the position. When the lower photoelectric switch 4304 arranged on the upper side detects the sliding seat 4301, the sliding seat 4301 moving downwards moves in place, and when the lower photoelectric switch 4304 located at the bottommost part detects the sliding seat 4301, the output of the maximum buffer amount of the buffer mechanism 43 is reached, at this time, the adhesive tape buffer device 43 will give an alarm, so as to promote the staff to transport the prepared adhesive tape 5 as soon as possible.
Based on the above overall structure, in this embodiment, when there is no adhesive tape 5 input outside the substrate 42 of the buffer device, the feeding mechanism 41 clamps the adhesive tape 5 and stops conveying the adhesive tape 5, and at the same time, the adhesive tape 5 on the buffer mechanism 43 starts to be used, that is, the driving motor drives the synchronous belt 4307 to rotate, and the buffer wheel set slowly moves downwards and outputs the buffered adhesive tape 5 due to the action of the synchronous belt 4307, where the rotation speed of the driving motor is controlled by the adhesive tape detection switch described below.
After the material roll feeding device finishes preparing the material, the glue head of the new glue strip 5 is adhered to the tail part of the glue strip 5 clamped on the new glue strip 5, so that the glue head and the glue strip are connected, and when the feeding mechanism 41 is restarted, the new glue strip 5 is conveyed. Under the effect of driving motor, hold-in range 4307 drives the buffer memory wheelset and rises gradually, and when rising to the last photoelectric switch 4302 at top, driving motor stops rotating with sending into mechanism initiative area driving motor 4110 simultaneously, and adhesive tape 5 accomplishes buffering once more this moment, and adhesive tape 5 that bonds on the door is all provided by the new material book that the outside was deposited.
In this embodiment, the adhesive tape 5 can be cached by about 65 meters by adopting the caching mechanism 43, the requirement for the adhesive amount of the adhesive tapes 5 of fourteen vehicle doors can be met, and the adhesive tape can be cached for fourteen minutes according to one caching beat in one minute, and the time is enough to finish the stock preparation, so that the purpose that the production line is not stopped when the adhesive tapes 5 are switched to be rolled up is achieved.
The aforementioned feeding mechanism 44 includes a feeding wheel rotatably disposed on the buffer device base 42, a rotary power device for driving the feeding wheel to rotate, a linear power device disposed on the buffer device base 42, and a pressing wheel 4410 disposed on the power output end of the linear power device, and the pressing wheel 4410 can be moved closer to or farther from the feeding wheel by the driving of the linear power device.
Based on the design concept of the dispensing mechanism 44 and with reference to fig. 6 and 7, in order to guide the adhesive tape 5 to be fed onto the dispensing wheel, a transition wheel 4401 rotatably disposed on the buffer device base body 42 is disposed upstream of the dispensing mechanism 44 along the adhesive tape 5 feeding direction, and the adhesive tape 5 output from the buffer mechanism 43 enters the dispensing mechanism 44 after passing around the transition wheel 4401.

In this embodiment, to improve the feeding effect of the rubber strip 5, the rubber strip 5 is spirally wound on the upper feeding wheel 4409 and the lower feeding wheel 4407, three guide grooves for guiding the rubber strip 5 during conveying are configured in the circumferential direction of the upper feeding wheel 4409, two guide grooves are formed on the lower feeding wheel 4407, and the rubber strip 5 is specifically spirally wound in the corresponding guide grooves of the upper feeding wheel 4409 and the lower feeding wheel 4407. In addition, in order to improve the use effect of the pressing wheel 4410, an annular protrusion is convexly formed on the annular pressing wheel 4410 in the circumferential direction, and the annular protrusion can press the adhesive tape 5 in the guide groove, so that the effect of the adhesive tape 5 in conveying is improved.
Further, since the adhesive tape 5 is spirally wound in the buffer mechanism 43 a plurality of times, the adhesive tape 5 being fed out is liable to be twisted, and the adhesive effect of the adhesive tape 5 is affected, and therefore, in this embodiment, the feed-out mechanism guide block 4408 having the guide hole 44081 following the cross section of the adhesive tape 5 is provided downstream of the feed-out mechanism 44. As shown in fig. 6 and 8, the feeding mechanism guide block 4408 has two guide holes 44081 arranged up and down, the feeding mechanism guide block 4408 is fixed on the buffer device base body 42, and the adhesive tape 5 input by the buffer mechanism 43 can respectively pass through the two guide holes 44081 so as to guide the twisted adhesive tape 5 to feed back in the right direction.
The buffer mechanism 43 in this embodiment needs to manually wind the adhesive tape 5 when it is used for the first time. Specifically, the adhesive tape 5 passing through the transition wheel 4401 is wound around the innermost guide groove of the upper feed-out wheel 4409, then passes through the guide hole 44081 positioned on the inner side of the feed-out mechanism guide block 4408, then sequentially passes through the innermost guide groove of the lower feed-out wheel 4407 and the guide groove at the middle position of the upper feed-out wheel 4409, then passes through the guide hole 44081 positioned on the outer side of the feed-out mechanism guide block 4408, and finally passes through the outer guide groove of the lower feed-out wheel 4407 and the outermost guide groove of the upper feed-out wheel 4409, thereby completing the winding of the adhesive tape 5. When the adhesive tape 5 needs to be conveyed, the pressing wheel 4410 is close to the upper feeding-out wheel 4409, and the two annular protrusions on the pressing wheel 44respectively press the adhesive tape 5 in the middle guide groove and the outermost guide groove of the upper feeding-out wheel 4409.

And the pressing force of the pressing wheel 4410 on the rubber strip 5 is adjustable, so that the requirement on the tension of the rubber strip 5 is reduced, and the problem of stretching is reduced. In addition, the pinch roller 4410 and the feed-out mechanism guide block 4408 can also effectively prevent the adhesive tape 5 from deviating in a free state.
In addition, for further controlling the stretching state of the adhesive tape 5 in the conveying process, the stretching of the adhesive tape 5 in the conveying process is effectively prevented, and meanwhile, the next bonding process can be ensured to run at a stable speed and is not influenced by the previous process. In this embodiment, the detection mechanism is also disposed downstream of the feeding mechanism 44, and the detection mechanism includes two sets of adhesive tape detection switches disposed on the buffer device substrate 42 and spaced apart from each other.

And when the rubber strip 5 is positioned in the middle of the channel, the tensile rate of the rubber strip 5 is good.

Of course, the strip detection switch may be a proximity switch in the prior art, in addition to a photoelectric switch. The distance between the photoelectric switches can be adjusted according to the use condition, so as to achieve better use effect.
Under the condition that the tensioning force of adhesive tape 5 diminishes, adhesive tape 5 can produce the downward removal, after third photoelectric switch 4405 detected adhesive tape 5, then need reduce the rotational speed of seeing off wheel drive motor 4411 to accelerate the conveying speed of next bonding process, with the seeing off that slows down adhesive tape 5, thereby make adhesive tape 5 fall to between second photoelectric switch 4403 and the third photoelectric switch 4405. When the adhesive tape 5 moves down rapidly to the fourth photoelectric switch 4406 for detection, the sending-out wheel driving motor 4411 needs to be turned off, and the redundant adhesive tape 5 is output through the next bonding process, so that the tension of the adhesive tape 5 is improved, the adhesive tape 5 moves up to a position between the second photoelectric switch 4403 and the third photoelectric switch 4405, and the sending-out wheel driving motor 4411 is turned on to work at the moment.
