[0002] Traditional automatic high-temperature glue machines for gold finger application use mechanical blind application and are unable to detect whether the tape is correctly applied. If the staff cannot detect whether the tape is aligned in place after changing the tape, once the tape is misaligned, due to the repetitive nature of the mechanical action, the high-temperature tape will continue to be applied off-center, not properly applied (not tightly), and other defects will occur. Regardless of whether the tape is applied too high or too low, it will cause the gold finger to wear or even fail, seriously affecting product quality. Therefore, the defects of existing glue machines include: the inability to manually detect and judge the accuracy of glue application, and the need to manually adjust the reference position of glue application for tapes of different widths, resulting in low work efficiency, poor accuracy, and the instability of the glue application effect, which directly affects the quality of the product.

[0038] Typical embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the description and drawings are intended to be illustrative in nature and not to limit the present invention.

[0039] In the following description of different exemplary embodiments of the present invention, reference is made to the accompanying drawings, which form a part of the present invention and in which are shown by way of example different exemplary structures, systems and steps that can implement aspects of the present invention. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps can be used, and structural and functional modifications can be made without departing from the scope of the present invention. Moreover, although the terms "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present invention, these terms are used herein for convenience only, for example, according to the directions of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present invention.

[0040] See Figure 1 , which represents a partial perspective view of the adhesive application device proposed in the present invention. In this exemplary embodiment, the adhesive application device proposed in the present invention is described using the example of applying high-temperature adhesive tape 201 to a gold finger. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of the present invention to adhesive application devices of other types or uses. Such changes remain within the scope of the principles of the adhesive application device proposed in the present invention.

[0041] like Figure 1 As shown in this embodiment, the adhesive laminating device proposed by the present invention at least includes a machine 100, an adhesive disc 200, a guide mechanism 300, a light source 400, an image acquisition unit 500 and a control unit. Figure 2 , Figure 2 7 is a partial perspective view of another angle of the adhesive application device that can embody the principle of the present invention; Figure 32 represents a front view of a portion of the structure of a glue-applying device that embodies the principles of the present invention, specifically illustrating the coordination between light source 400 and a portion of adhesive tape 201. The following, in conjunction with the aforementioned figures, details the structure, connection method, and functional relationship of the main components of the glue-applying device of the present invention.

[0042] like Figures 1 to 3 As shown, in this embodiment, the adhesive reel 200 is mounted on the machine 100 and can be used to wind an adhesive tape 201, such as a roll of adhesive tape 201. The center of the adhesive tape 201 is marked with a centerline L2. The guide mechanism 300 is mounted on the machine 100 and spaced apart from the adhesive reel 200. The guide mechanism includes a liftable guide wheel 310. The guide wheel 310 is configured to allow the extended end of the adhesive tape 201 to pass through, allowing the extended end of the adhesive tape 201 to be guided by the guide wheel 310 to the gluing position of the gluing mechanism. The light source 400 and the image acquisition unit 500 are respectively mounted on the machine 100, and are located on either side of the line connecting the adhesive reel 200 and the guide mechanism 300. The light source 400 is capable of emitting light toward the adhesive tape 201 (the portion between the adhesive disc 200 and the guide roller 310). Because the adhesive tape 201 is made of a transparent or translucent material, the light emitted by the light source 400 can pass through the adhesive tape 201 and reach the image capture unit 500. Furthermore, a reference line L1 is provided at the light output of the light source 400, which can be reflected as a shadow in the light emitted by the light source 400. The image capture unit 500 can capture image information of the center line L2 of the adhesive tape 201 and the reference line L1. The control unit is connected to the image acquisition unit 500 and the guide mechanism 300, respectively. The control unit can determine the relative position of the center line L2 and the reference line L1 based on the image information collected by the image acquisition unit 500, such as whether the center line L2 deviates from the reference line L1, whether the center line L2 deviates upward or downward from the reference line L1, and the distance by which the center line L2 deviates upward or downward from the reference line L1. Based on this information, the control unit controls the height of the guide wheel 310. As the guide wheel 310 rises or falls, the position of the adhesive tape 201 wrapped around the guide wheel 310 can also rise or fall accordingly, thereby adjusting the height of the adhesive tape 201. Through the above design, the present invention can achieve real-time detection and automatic adjustment of the position accuracy of the adhesive tape 201, avoiding the situation where the adhesive tape 201 is repeatedly deviated or not properly applied, ensuring high product quality, and eliminating the need for manual adjustment, thereby improving production efficiency and reducing labor intensity.

[0043] Optionally, in this embodiment, the reference line L1 of the light source 400 can be set by taking a center line and detecting the centers of the two holes, taking the average position of the two centers, and marking a straight line at the average position, which is the reference line L1.

[0044] Alternatively, as Figure 1 and Figure 2 As shown, in this embodiment, the guide mechanism 300 may include a wheel frame 320 and a drive unit. Specifically, the wheel frame 320 has a fixed portion 321 and a lifting portion 322. The fixed portion 321 is disposed on the machine 100, and the lifting portion 322 is liftably disposed on the fixed portion 321. The lifting portion 322 can be used to set the guide wheel 310. The drive unit is transmission-connected to the wheel frame 320. The drive unit can drive the lifting portion 322 to rise and fall relative to the fixed portion 321, thereby driving the guide wheel 310 to rise and fall relative to the machine 100. On this basis, a control unit is connected to the drive unit, and the control unit can control and adjust the height of the guide wheel 310 by controlling the drive unit.

[0045] Furthermore, in this embodiment, the driving unit may be a motor.

[0046] Alternatively, as Figure 1 and Figure 2 As shown, in this embodiment, the gluing device proposed by the present invention may further include a first bracket 410. Specifically, the first bracket 410 is disposed on the machine 100. On this basis, the light source 400 can be disposed on the first bracket 410 in a height-adjustable manner. Through the above design, the present invention can utilize the first bracket 410 to achieve the arrangement of the light source 400 on the machine 100, and at the same time can achieve the height adjustment of the light source 400 relative to the machine 100, so that the light source 400 can adapt to the arrangement requirements of the reference line L1 at different heights, thereby expanding the application range of the gluing device for tapes 201 of various specifications.

[0047] Furthermore, if Figure 1 and Figure 2 As shown, based on the design that the light source 400 is adjustable in height on the first bracket 410, in this embodiment, a first guide groove can be provided on the first bracket 410, and the extension direction of the first guide groove is perpendicular to the machine 100. On this basis, the light source 400 can be detachably provided on the first bracket 410 through a first connecting member, and the first connecting member is passed through the first guide groove, so that the light source 400 can be selectively positioned relative to the first bracket 410 along the first guide groove. In addition, the first connecting member can be, but is not limited to, a bolt with a guide rod, which can be passed through the guide rod and slidably fitted in the first guide groove. Through the above design, the present invention can achieve the positioning of the light source 400 and the first bracket 410 when it is at different height positions.

[0048] Furthermore, if Figure 1 and Figure 2 As shown, based on the design that the light source 400 is height-adjustably mounted on the first bracket 410, in this embodiment, a first limiting plate 412 can be provided on the top of the first bracket 410. The first limiting plate 412 can limit the highest mounting position of the light source 400 on the first bracket 410. Through the above design, the present invention can prevent the light source 400 from moving out of the first bracket 410 during upward adjustment.

[0049] Alternatively, as Figure 1 and Figure 2 As shown, in this embodiment, the adhesive laminating device proposed by the present invention may further include a second bracket 510. Specifically, the second bracket 510 is disposed on the machine platform 100. On this basis, the image acquisition unit 500 can be disposed on the second bracket 510 in a height-adjustable manner. Through the above design, the present invention can utilize the second bracket 510 to realize the placement of the image acquisition unit 500 on the machine platform 100, and can also realize the height adjustment of the image acquisition unit 500 relative to the machine platform 100, thereby enabling the image acquisition unit 500 to adapt to the acquisition needs of the reference line L1 at different heights, thereby expanding the application range of the adhesive laminating device for various specifications of adhesive tape 201.

[0050] Furthermore, if Figure 1 and Figure 2 As shown, based on the design in which the image acquisition unit 500 is height-adjustably mounted on the second bracket 510, in this embodiment, a second guide slot 511 may be provided on the second bracket 510, extending perpendicularly to the machine platform 100. Based on this, the image acquisition unit 500 can be removably mounted on the second bracket 510 via a second connecting member, which extends through the second guide slot 511, allowing the image acquisition unit 500 to be selectively positioned relative to the second bracket 510 along the second guide slot 511. Furthermore, the second connecting member may be, but is not limited to, a bolt having a guide rod, which can be passed through the guide rod and slidably engaged with the second guide slot 511. Through the above-described design, the present invention enables the image acquisition unit 500 to be positioned relative to the second bracket 510 at different heights.

[0051] Furthermore, if Figure 1 and Figure 2 As shown, based on the design that the image acquisition unit 500 is height-adjustably mounted on the second bracket 510, in this embodiment, a second limit plate 512 can be installed on the top of the second bracket 510. This second limit plate 512 can limit the highest mounting position of the image acquisition unit 500 on the second bracket 510. Through this design, the present invention can prevent the image acquisition unit 500 from moving out of the second bracket 510 during upward adjustment.

[0052] Optionally, in this embodiment, the image acquisition unit 500 may be a camera.

[0053] Optionally, in this embodiment, the detection, calculation and comparison functions of the control unit can be implemented based on a single chip microcomputer.

[0054] Optionally, in this embodiment, the control unit may include a visual system that can display information such as the image information captured by the image acquisition unit 500, the position deviation direction and value of the center line L2 relative to the reference line L1 calculated by the control unit, and the height adjustment control status of the guide wheel 310, thereby enabling the user to promptly extract relevant information and working status.

[0055] It should be noted that the adhesive application devices shown in the drawings and described in this specification are merely a few examples of the many types of adhesive application devices that can employ the principles of the present invention. It should be clearly understood that the principles of the present invention are in no way limited to any detail or component of the adhesive application devices shown in the drawings or described in this specification.

[0056] Based on the above detailed description of an exemplary embodiment of the gluing device proposed in the present invention, an exemplary embodiment of a method for adjusting and controlling the height of an adhesive tape of the gluing device proposed in the present invention will be described below.

[0057] See Figure 4 , which representatively illustrates a flow chart of the method for controlling the height adjustment of the adhesive tape of a gluing device according to the present invention. In this exemplary embodiment, the method for controlling the height adjustment of the adhesive tape is described using the adhesive tape device according to the present invention as an example. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of the present invention to gluing devices of other types or uses. These modifications will still fall within the scope of the principles of the method for controlling the height adjustment of the adhesive tape of a gluing device according to the present invention.

[0058] like Figure 4 As shown, in this embodiment, the tape height adjustment control method of the gluing device proposed by the present invention can control the height of the guide wheel of the gluing device proposed by the present invention and described in detail in the above embodiments. The control method includes:

[0059] Step S1: Turn on the machine, and the control unit determines whether there is a tape extending and whether the light source is turned on through the image acquisition unit;

[0060] Step S2: When the tape is extended and the light source is turned on, the image acquisition unit acquires image information of the center line and the reference line, and the control unit determines whether the center line is offset upward or downward relative to the reference line based on the image information;

[0061] Step S3: When the control unit determines that an offset occurs, it controls the guide mechanism to adjust the guide wheel to descend or ascend, so as to correct the relative position of the center line and the reference line.

[0062] Optionally, in this embodiment, for step S1, after the machine is started, based on the image information collected by the image acquisition unit, when the control unit detects at least one of the situations of no tape and the light source not being turned on, an alarm prompt is issued through the alarm unit.

[0063] Optionally, in this embodiment, the image acquisition unit may periodically monitor image information of the centerline and the baseline. When the control unit determines that deviation has occurred, the image acquisition unit acquires image information of the centerline and the baseline in real time until correction is complete, at which point periodic monitoring is resumed. In other embodiments, the image acquisition unit may also maintain real-time monitoring of image information after the adhesive laminating device is activated, and this is not a limitation to this embodiment.

[0064] Furthermore, based on the process design of the image acquisition unit employing periodic detection at the beginning of detection and after correction, in this embodiment, the detection period of the periodic detection of the image acquisition unit can be 1 minute to 5 minutes, for example, 1 minute, 2 minutes, 4 minutes, 5 minutes, etc. In other embodiments, the detection period of the periodic detection of the image acquisition unit can also be less than 1 minute, or can be greater than 5 minutes, for example, 50 seconds, 6 minutes, etc., and is not limited to this embodiment.

[0065] Furthermore, in this embodiment, the detection period of the periodic detection of the image acquisition unit may preferably be 3 minutes.

[0066] Optionally, in this embodiment, in step S2, the control unit may compare the upward or downward offset of the centerline relative to the baseline with a first preset value. When the offset is greater than or equal to the first preset value, the control unit determines that a deviation has occurred. In other words, if the offset of the centerline relative to the baseline calculated by the control unit is less than the first preset value, the control unit will not temporarily determine that the tape has deviated, i.e., will not adjust the height of the guide wheel. In other embodiments, the control unit may also immediately determine that the tape has deviated when the comparison and calculation result shows that the centerline is offset from the baseline, and this is not limited to this embodiment.

[0067] Furthermore, based on the process design in which the control unit determines whether offset occurs based on a comparison between the offset amount and a first preset value, in this embodiment, the first preset value can be 1 mm to 5 mm, such as 1 mm, 2 mm, 4 mm, 5 mm, etc. In other embodiments, the first preset value can also be less than mm, or greater than 5 mm, such as 0.9 mm, 5.5 mm, etc., and is not limited to this embodiment.

[0068] Furthermore, in this embodiment, the first preset value may preferably be 3 mm. In addition, taking the first preset value of 3 mm as an example, it actually includes the situation where the center line is 3 mm higher than the reference line, and the center line is 3 mm lower than the reference line, that is, the first preset value is actually ±3 mm.

[0069] Furthermore, based on a process design in which the control unit determines whether offset has occurred based on a comparison between the offset and a first preset value, in this embodiment, in step S3, during the guide wheel height adjustment process, the control unit controls the guide mechanism to stop raising and lowering the guide wheel when the offset (measured in real time) is less than or equal to a second preset value, where the second preset value is less than the first preset value. In other embodiments, the control unit may also control the guide mechanism to stop raising and lowering the guide wheel when the offset is zero, and the present invention is not limited to this embodiment.

[0070] Furthermore, based on the process design of the control unit stopping the adjustment control of the guide wheel when the value is less than or equal to the second preset value, in this embodiment, the second preset value can be 0.5 mm to 1 mm, such as 0.5 mm, 0.6 mm, 0.8 mm, 1 mm, etc. In other embodiments, the second preset value can also be less than 0.5 mm, or greater than 1 mm, such as 0.4 mm, 1.1 mm, etc., but the second preset value must be less than the first preset value, and this is not limited to this embodiment.

[0071] Further, in this embodiment, the second preset value may preferably be 0.7 mm.

[0072] Based on the above detailed description of the gluing device and the tape height adjustment control method thereof proposed by the present invention, the working principle of controlling the gluing device using the control method will be described below:

[0073] When the machine starts to operate, the image acquisition unit first detects the image information, and the control unit determines whether there is tape (that is, whether the tape is wrapped around the guide wheel) and whether the light source is turned on. When the control unit determines that there is tape and the light source is turned on, the control unit controls the image acquisition unit to detect whether the position of the tape is offset upward or downward every 3 minutes, that is, specifically detects whether the center line is offset upward or downward relative to the baseline. According to the image information periodically collected by the image acquisition unit, when the control unit calculates that the position deviation between the center line and the baseline reaches ±3mm, the control unit controls the drive unit to work and adjust the guide wheel to adjust the height, thereby adjusting the height of the tape, thereby achieving a correction effect. During the adjustment process of the drive unit, the image acquisition unit detects the position deviation between the center line and the baseline in real time. When the position deviation is reduced to within ±0.7mm, the control unit controls the drive unit to stop working. At this time, after the image acquisition unit detects that the tape position adjustment is completed, it turns off the real-time detection mode and restores the periodic detection mode of detecting every 3 minutes.

[0074] It should be noted that the methods for controlling the height adjustment of the adhesive tape of a gluing device illustrated in the accompanying drawings and described in this specification are merely examples of many control methods that can employ the principles of the present invention. It should be clearly understood that the principles of the present invention are in no way limited to any details or steps of the methods for controlling the height adjustment of the adhesive tape of a gluing device illustrated in the accompanying drawings or described in this specification.

[0075] In summary, the adhesive laminating device proposed by the present invention comprises a light source and an image acquisition unit disposed on either side of the line connecting the adhesive disc and the guide mechanism, and the guide mechanism includes a liftable guide wheel. The present invention utilizes the image acquisition unit to capture image information of the centerline of the adhesive tape and the reference line of the light source, allowing the control unit to determine the relative position of the centerline and the reference line based on the image information and to adjust the height of the guide wheel accordingly. Through the above-described design, the present invention is able to achieve real-time detection and automatic adjustment of the adhesive tape's position accuracy, preventing the adhesive tape from being repeatedly applied off-center or incompletely, ensuring high product quality while eliminating the need for manual adjustment, improving production efficiency, and reducing labor intensity.
