Description

Technical Field

[0001] The utility model relates to the field of automatic glue - sticking devices, in particular to an automatic glue - sticking device for automobile roofs. Background Art

[0002] With the development of economy and technology, automobiles have become more and more common in life. During the production process of automobiles, it is necessary to perform glue - sticking treatment on the gaps of the automobile roof, which can play roles such as decoration, filling gaps, covering welds, and waterproofing.

[0003] At present, common glue - sticking devices generally use manual labor or a driving device to drive a glue - sticking gun to move, and the glue strip wound on the glue - sticking gun automatically sticks to the automobile roof. Compared with manual glue - sticking, since its movement path has been set in advance, it can be stuck more neatly and with higher efficiency.

[0004] However, automatic glue - sticking also has drawbacks. During the glue - sticking process, due to factors such as the quality of the glue strip itself or the processing error of the automobile roof, the glue strip often breaks. After the glue strip breaks, the driving device will still continue to drive the glue - sticking gun to move, and the glue - sticking gun cannot stick normally. The driving device only does useless work and wastes energy. Therefore, generally, manual supervision is still required during automatic glue - sticking. Once it is found that the glue breaks, the machine needs to be stopped in time and the glue strip needs to be adjusted. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model aims to provide an automatic glue - sticking device for automobile roofs to solve the problem that the breakage of the glue strip in the glue - sticking gun cannot be detected in time in the prior art. The specific technical solutions are as follows:

[0006] An automatic glue - sticking device for automobile roofs includes a mounting frame. A pressing roller and a driven roller are mounted on the mounting frame. The pressing roller and the driven roller are connected by a glue strip. A supporting plate is arranged at the pressing roller to support the glue strip. The supporting plate is arranged with a gap from the pressing roller for the glue strip to pass through. A side plate is provided on one side of the mounting frame. An induction and recognition device is mounted on the side plate. The induction and recognition device is arranged facing the side of the driven roller. The induction and recognition device is electrically connected to a control device, and the control device is electrically connected to an alarm device to control the start and stop of the alarm device;

[0007] A marking part is arranged on one side of the driven roller close to the side plate. The marking part rotates with the driven roller. The induction and recognition device can recognize the marking part and transmit a signal to the control device.

[0008] As a preferred embodiment: The induction and recognition device is a laser sensor or an infrared sensor.

[0009] As a preferred embodiment: The length direction of the marking portion is arranged along the radial direction of the driven roller.

[0010] As a preferred embodiment: The driven roller includes a positioning shaft fixedly installed on the side plate and a bearing sleeved outside the positioning shaft, and a rubber strip is wound around the outside of the bearing;

[0011] The marking portion is arranged on the side surface of the outer ring of the bearing, and the induction and identification device is arranged towards the outer ring of the bearing.

[0012] As a preferred embodiment: The number of the marking portions is multiple, and the multiple marking portions are evenly arranged along the circumferential direction of the outer ring of the bearing.

[0013] As a preferred embodiment: The marking portion is a strip-shaped member with a color different from other positions of the driven roller.

[0014] As a preferred embodiment: A photoelectric sensing device is further installed on the side plate, and the photoelectric sensing device is arranged towards the side surface of the inner layer of the rubber strip wound outside the driven roller and is electrically connected to the control device.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the automatic glue pasting device for an automobile ceiling disclosed by the utility model, by arranging a side plate on the mounting frame, the induction and identification device installed on the side plate can identify the marking portion on the side surface of the driven roller. Under normal circumstances, since the pressing roller drives the driven roller to rotate through the rubber strip, the induction and identification device should detect the marking portion once every certain period of time and feed back to the control device. If the induction and identification device does not detect the marking portion for a long time, or continuously detects the marking portion, it indicates that the rubber strip may be broken or the rubber strip has been used up, resulting in the pressing roller being unable to drive the driven roller to rotate. After the induction and identification device transmits the signal to the control device, the control device determines an abnormality and activates the alarm device to warn the staff. After receiving the warning, the staff can timely repair, replace or adjust the rubber strip, avoiding the subsequent useless work of the glue pasting device, effectively saving costs and improving the efficiency of automatic glue pasting.

Specific embodiments

[0021] The following describes the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0022] The following illustrates the embodiments of the present disclosure through specific examples. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0023] Embodiment 1

[0024] Combined with Figures 1 to 3 As shown, an automatic glue pasting device for a car roof includes a mounting frame 1. The mounting frame 1 includes a side plate 10 and a handle part 11. This device can be separately removed and operated by manually holding the handle part 11, or a power system can be set to control a manipulator to drive the handle part 11 for automatic glue pasting. A pressing roller 2 and a driven roller 3 are installed on the side plate 10. A support plate 5 is integrally connected to the handle part 11. A small gap is formed between the end of the support plate 5 and the pressing roller 2 for the rubber strip 4 to pass through, so as to position the rubber strip 4 to a certain extent. The function of the pressing roller 2 is to press the rubber strip 4 after pasting the rubber strip 4 on the car roof. The rubber strip 4 is wound around the outside of the driven roller 3. The pressing roller 2 is connected to the driven roller 3 through the rubber strip 4. Therefore, when the pressing roller 2 presses the rubber strip 4, it drives the driven roller 3 to rotate, thereby realizing automatic glue pasting.

[0025] As Figure 2 shown, the driven roller 3 includes a positioning shaft 31 fixedly arranged on the side plate 10 and a bearing 32 outside the positioning shaft 31. The rubber strip 4 is wound around the outside of the bearing 32.

[0026] In order to deal with the situation where the rubber strip 4 breaks and the power system does useless work, in this embodiment, an induction recognition device 6 is provided on the side plate 10. The induction recognition device 6 can adopt an infrared sensor or a laser sensor. One or more marking parts 30 are arranged on the outer side surface of the outer ring of the bearing 32. In the case of multiple marking parts 30, the multiple marking parts 30 are evenly arranged along the circumferential direction of the outer ring of the bearing 32, which can avoid the situation of missed detection.

[0027] The marking part 30 is preferably a strip-shaped part arranged radially along the driven roller 3, which is easier to be recognized. Its material or color is different from the surrounding parts, so that it can be recognized by the induction recognition device 6. Under normal circumstances, the pressing roller 2 drives the driven roller 3 to rotate. The induction recognition device 6 can recognize the marking part 30 at regular intervals. The induction recognition device 6 feeds back the signal to a control device such as a plc. If the marking part 30 is not recognized for a long time or is continuously recognized, it means that the rubber strip 4 may break or the rubber strip 4 has been used up. As a result, the pressing roller 2 cannot drive the driven roller 3 to rotate, and the induction recognition device 6 controls the alarm device to give an alarm, reminding the staff to replace and adjust the rubber strip 4 in time.

[0028] Although the induction recognition device 6 can judge whether the rubber strip 4 has been used up by recognizing whether the driven roller 3 rotates, this method cannot predict in advance and cannot accurately distinguish whether the rubber strip 4 breaks or the rubber strip 4 has been used up. Therefore, in this embodiment, a photoelectric sensing device 7 is also provided on the side plate 10. The photoelectric sensing device 7 is a reflection-type sensor. If it is blocked within a certain distance, the light reflection is received by the receiver and the signal is fed back to the control device, such as Figure 2 and Figure 3 As shown, the photoelectric sensing device 7 is arranged facing the side surface of the rubber strip 4 wound outside the driven roller 3, and its photoelectric induction position 70 is located at the inner layer of the rubber strip 4. When the rubber strip 4 is almost used up, the overall thickness of the rubber strip 4 becomes thinner until the light emitted by the photoelectric sensing device 7 cannot be reflected. At this time, the control device turns on the alarm device to give an alarm. The control device can distinguish and process the abnormal signals fed back by the photoelectric sensing device 7 and the induction recognition device 6, and drive different alarm devices or alarm methods to give an alarm, such as different alarm ringtones and different flash degrees. Therefore, setting the photoelectric sensing device 7 can not only give an alarm in time when the rubber strip 4 is almost used up, but also set different alarm methods so that the staff can judge at the first time that the rubber strip has been used up and can replace it in time.

[0029] The utility model recognizes the usage situation of the rubber strip 4 by setting the induction recognition device 6 and the photoelectric sensing device 7, gives an alarm in time when an abnormality occurs, avoids the power system from doing useless work, reminds the staff to replace and adjust the rubber strip in time, reduces the processing cost, improves the rubber pasting efficiency, and is suitable for popularization and use.
