For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood in combination with the specific circumstances.

[0047] The utility model will be explained in detail below with reference to the drawings and in combination with the embodiments.

[0048] Embodiment one

[0049] The embodiment relates to a gluing device, to solve the problems of complex structure, poor use stability and low qualified rate of adhesive tape 1101 in the prior art.

[0050] Overall, the gluing device comprises a driving part, a glue gun 2 arranged on the driving part, a blocking piece 4 connected to the driving end of the driving part, and a glue pipe 3 arranged on the glue gun 2. The glue gun 2 has a glue outlet channel 100 and a glue nozzle 203 arranged at the end of the glue outlet channel 100. The blocking piece 4 is inserted into the glue outlet channel 100 and can act under the driving of the driving part to block the glue nozzle 203. One end of the glue pipe 3 is communicated with the glue outlet channel 100, and the other end is used to connect with an external glue supply device.

[0051] The gluing device has the advantages of simple structure and high use stability compared with the prior art, thereby improving the qualified rate of the adhesive tape 1101.

[0052] Based on the overall introduction above, an exemplary structure of the gluing device in the embodiment is shown in Figures 1 to 3 As a preferred embodiment, the driving part comprises a cylinder 1, and the blocking piece 4 is connected to the piston 103 of the cylinder 1. The cylinder 1 is a mature power supply element and can provide stable and reliable linear motion power, thereby driving the blocking piece 4 to act and open and close the glue nozzle 203.

[0053] Specifically, as shown in Figure 3 and Figure 5 The cylinder 1 comprises a cylinder body 102 with a cavity formed therein, the top of the cavity is open, and a cylinder cover 101 is arranged at the top of the cylinder body 102 to block the opening. The bottom of the cylinder body 102 is provided with two extension parts 104 arranged oppositely and extending downward, and a bottom cover 105 is connected between the two extension parts 104. The piston 103 is slidingly arranged in the cavity, the blocking piece 4 is columnar, and the blocking piece 4 passes through the bottom of the cylinder body 102 and the bottom cover 105.

[0054] In a specific implementation, by adjusting the parameters such as the air intake amount, air exhaust amount, and air pressure of the air cylinder 1, the movement speed and stroke of the piston 103 can be flexibly controlled, and the action of the blocking member 4 in the glue outlet channel 100 can be accurately adjusted. For example, when it is required to quickly block the glue nozzle 203, the air intake amount can be increased to make the piston 103 quickly extend to drive the blocking member 4 to block; when it is required to slowly open the glue nozzle 203, the air exhaust amount can be controlled to make the piston 103 slowly retract, so that the blocking member 4 slowly leaves the glue nozzle 203.

[0055] In addition, the air cylinder 1 itself has a relatively compact structure, and occupies a small space in the entire glue application device. Using the air cylinder 1 as the driving part helps to maintain the compactness of the overall structure of the glue application device. It can be understood that, in addition to the air cylinder 1, other products capable of outputting linear driving force can also be used as the driving part of the embodiment, as long as the use requirements are met.

[0056] As a preferred embodiment, the glue pipe 3 is provided with a flow detection part 6 for detecting the amount of glue in the glue pipe 3. Here, by detecting the amount of glue in the glue pipe 3 through the flow detection part 6, the consumption of glue during the current glue application process can be known, thereby effectively preventing waste of glue due to excessive supply of glue, and also preventing problems such as incomplete glue application or interruption of work due to insufficient amount of glue, thereby improving the efficiency and quality of the glue application work.

[0057] The flow detection part 6 of the embodiment relies on the flow of glue in the glue pipe 3 to realize the detection function. In a specific implementation, the flow detection part 6 in the embodiment can use a flow sensor in the prior art, which can detect the flow of glue in the glue pipe 3 and whether there are air bubbles. If the flow detection part 6 detects that there are air bubbles in the glue or the flow of glue is not within a reasonable range, an alarm is prompted.

[0058] As a preferred embodiment, as shown in Figure 3 and Figure 5 The glue gun 2 includes a gun body 201 having a glue outlet channel 100. By rotating the joint 202 provided outside the gun body 201 through the rotating part, the annular channel 200 is formed between the joint 202 and the gun body 201, which is in communication with the glue outlet channel 100. The glue pipe 3 is provided on the joint 202 and is in communication with the glue outlet channel 100 through the annular channel 200. Here, the joint 202 is arranged outside the gun body 201, and the annular channel 200 is formed between the joint 202 and the gun body 201, which can communicate the glue pipe 3 with the glue outlet channel 100, thereby facilitating to ensure the glue outlet effect of the glue nozzle 203.

[0059] Specifically, the gun body 201 has a main body portion 2011 extending along the sliding direction of the blocking member 4, and an end portion portion arranged at the top end of the main body portion 2011 and protruding radially outward. The glue outlet channel 100 extends through the main body portion 2011 and the end portion portion along the axial direction of the gun body 201. The glue nozzle 203 is arranged at the bottom of the main body portion 2011, and the blocking member 4 is arranged in the main body portion 2011 and located above the top end of the glue nozzle 203. When the blocking member 4 is driven to slide up and down by the driving portion, the top end of the glue nozzle 203 can be blocked or unblocked.

[0060] As shown in Figure 4 , the gun body 201 is fixed on the driving portion by the top portion 2012 and arranged fixedly relative to the driving portion. A sealing structure is arranged between the top of the glue outlet channel 100 of the top portion 2012 and the blocking member 4. As an example of the structure, as shown in Figure 3 , the top end of the glue outlet channel 100 is provided with an embedding groove, and the sealing structure includes a first lock nut 10 embedded in the embedding groove, and the blocking member 4 passes through the first lock nut 10. The first lock nut 10 in the installed state is limited by the embedding groove and cannot move downward. The sealing structure further includes a first sealing ring 1002 arranged between the bottom of the embedding groove and the blocking member 4, and a second sealing ring 1001 arranged between the outer peripheral wall of the first lock nut 10 and the inner peripheral wall of the embedding groove. The sealing structure is simple in structure, easy to arrange and implement, and has good sealing effect.

[0061] The glue pipe 3 in the embodiment is arranged on the connector 202 and communicates with the glue outlet channel 100 through the annular channel 200 formed by the connector 202 and the gun body 201. In this way, a complete and orderly glue conveying path is formed between the glue pipe 3, the connector 202, the gun body 201 and the glue outlet channel 100. The rotatability of the connector 202 facilitates changing the direction and position of the glue pipe 3, which is beneficial to optimizing the layout of the entire glue coating device on site and improving the utilization rate of the working space. Specifically, the presence of the rotating portion allows the connector 202 to rotate flexibly relative to the gun body 201, which adjusts the relative positional relationship between the glue pipe 3 and the gun body 201 to a certain extent without affecting the normal transmission of glue in actual operation.

[0062] As shown in Figure 2 and Figure 3As shown in the drawings, as a preferred embodiment, the inner peripheral wall of the joint 202 is circular in cross section, and the outer peripheral wall is square in cross section. Of course, the shape of the cross section of the outer peripheral wall of the joint 202 can also be adjusted as needed. The joint 202 in this embodiment is sleeved on the main body portion 2011 of the gun body 201 and is located below the top portion 2012. The joint 202 is provided with a first bearing seat 2041 at each end, and a first bearing 204 is arranged in each first bearing seat 2041. The inner ring of the first bearing 204 is sleeved on the main body portion 2011. The joint 202 is rotatably arranged on the gun body 201 through the first bearing seat 2041 arranged above and below and the first bearing 204 thereon. The first bearing seat 2041 arranged above abuts against the top surface of the top portion 2012, and the second bearing 5 arranged below is blocked by the snap spring 205 arranged on the gun body 201, so that the joint 202 is located in the space defined between the top portion 2012 and the snap spring 205. The joint 202 cannot move along its own axis and can only rotate around its own axis.

[0063] To form the annular channel 200, two annular protrusions are arranged along the axial direction of the joint 202. The annular channel 200 is formed between the two annular protrusions, the inner peripheral wall of the joint 202, and the outer peripheral wall of the main body portion 2011. To ensure the sealing effect between the joint 202 and the gun body 201, a sealing assembly is arranged on each of the upper and lower sides of the annular channel 200 to seal between the joint 202 and the main body portion 2011.

[0064] As an example of the structure, as shown in the drawings, Figure 3 As shown in the drawings, a mounting groove is arranged on each of the upper and lower sides of the annular channel 200. The sealing assembly includes a first ring body 2021 and a second ring body 2022 arranged above and below in the mounting groove. An outer sealing ring 2023 is arranged between the outer peripheral wall of the first ring body 2021 and the outer peripheral wall of the joint 202. The first ring body 2021 is further provided with a flood plug 2024 located between the first ring body 2021 and the main body portion 2011. An inner sealing ring 2025 is arranged between the inner peripheral wall of the second ring body 2022 and the outer peripheral wall of the main body portion 2011.

[0065] In the embodiment, the outer sealing ring 2023 and the inner and outer cooperation of the pan seal 2024 are beneficial to improve the sealing between the first ring body 2021, the joint 202 and the main body 2011, and the inner sealing ring 2025 is also beneficial to improve the sealing between the joint 202 and the main body 2011. Further, the two sealing assemblies in the two installation grooves are symmetrically arranged, that is, the two second ring bodies 2022 are arranged on the upper and lower sides of the annular channel 200, and each first ring body 2021 is located outside the same side second ring body 2022. In order to further improve the use performance of the sealing assembly, the first ring body 2021 and the second ring body 2022 in the embodiment are made of metal material to improve the strength and durability of the ring body.

[0066] The rubber tube 3 in the embodiment is arranged on the joint 202 through the mounting seat 7, the mounting seat 7 is provided with a mounting hole for mounting the rubber tube 3 and an avoidance space 705 for avoiding the flow detection part 6. Here, the rubber tube 3 is connected with the mounting seat 7 through the mounting hole of the mounting seat 7, which is easy to arrange and implement, and through close cooperation, the rubber tube 3 can maintain a relatively stable position on the mounting seat 7, which is beneficial to avoid the shaking and displacement of the rubber tube 3 during the gluing process, thereby ensuring that the glue can be smoothly transmitted through the rubber tube 3. In addition, by arranging the avoidance space 705, the flow detection part 6 can be arranged in the mounting seat 7, and the flow detection part 6 can accurately detect the amount of glue in the rubber tube 3.

[0067] Specifically, as shown in Figure 1 and Figure 3 , the rubber tube 3 extends along the direction perpendicular to the axial direction of the gun body 201. In order to facilitate the installation of the rubber tube 3, the mounting seat 7 has a fixed plate 701 connected with one side wall of the joint 202, an installation block 702 arranged at the other end of the mounting seat 7 relative to the fixed plate 701, and two connecting plates 703 arranged between the fixed plate 701 and the installation block 702 and arranged opposite to each other.

[0068] The mounting hole is arranged through the mounting block 702 and the fixing plate 701 along the length direction of the mounting seat 7, and the rubber tube 3 is arranged on the mounting seat 7 by penetrating the first mounting hole 706 on the mounting block 702 and the second mounting hole 708 on the fixing plate 701 from outside to inside. In addition, a limiting surface is arranged on the mounting block 702 to abut against one end of the rubber tube 3, so as to limit the movement of the rubber tube 3 away from the gun body 201. A limiting groove is arranged on the side wall of the joint 202 to abut against the liquid outlet end of the rubber tube 3. Through the cooperation of the limiting surface and the limiting groove, the rubber tube 3 in the mounted state cannot move along the axial direction of the rubber tube 3, thereby improving the installation stability of the rubber tube 3. Corresponding to the liquid outlet of the rubber tube 3, a communication port is arranged on the joint 202 to communicate the rubber tube 3 and the annular channel 200, and the glue in the rubber tube 3 flows into the annular channel 200 through the communication port.

[0069] The avoiding space 705 is arranged between the fixing plate 701, the mounting block 702 and the two connecting plates 703. In this embodiment, the mounting seat 7 has a simple structure, is convenient to arrange and implement, is beneficial to the arrangement and installation of the flow detection part 6 and the rubber tube 3, and is beneficial to the lightweight design of the whole glue applying device. In this embodiment, the rubber tube 3 is fixed on the joint 202 through the mounting hole of the mounting seat 7, which greatly improves the installation stability of the rubber tube 3 compared with the connection mode of simply relying on the rubber tube 3 itself and the joint 202. During the long-time operation of the glue applying device, the rubber tube 3 can always keep in the correct position and stably transmit the glue, thereby reducing the probability of the occurrence of problems such as unstable glue supply or leakage caused by the displacement or loosening of the rubber tube 3. In addition, the arrangement of the flow detection part 6 in the avoiding space 705 of the mounting seat 7 is also beneficial to the compactness of the structure of the glue applying device.

[0070] Further, the mounting seat 7 is provided with a communication channel 704 communicating with the mounting hole, and the communication channel 704 is used to communicate with the external glue supply device. Through the arrangement of the communication channel 704 on the mounting seat 7, the glue in the external glue supply device can flow into the mounting hole through the communication channel 704, thereby facilitating the glue supply of the external glue supply device.

[0071] In some embodiments, as Figure 3 and Figure 7As shown in FIG. 7, the communication passage 704 is arranged on the mounting block 702. The bottom end of the communication passage 704 is arranged in communication with the first mounting hole 706, and the top end of the communication passage 704 extends upward and penetrates through the mounting block 702. An external glue supply device can be connected to the communication passage 704 through a pipeline, and glue can be delivered into the glue pipe 3 through the communication passage 704. The communication passage 704 is located outside the liquid inlet end of the glue pipe 3, and the glue in the external glue supply device flows into the first mounting hole 706 through the communication passage 704, and then flows into the glue pipe 3 through the first mounting hole 706. Considering that the first mounting hole 706 on the mounting block 702 is arranged in penetration, in order to prevent the glue from flowing out of the first mounting hole 706, a plug 707 is arranged at the end of the first mounting hole 706 away from the glue pipe 3.

[0072] The mounting seat 7 in the embodiment now integrates the functions of fixing the glue pipe 3, avoiding the flow detection part 6, and supplying glue, and becomes a highly integrated component. Such functional integration not only simplifies the overall structure of the glue applying device and reduces the number of components, but also facilitates installation, maintenance and management. During installation, only the correct connection of the mounting seat 7 with related components is needed to complete the setting of multiple functions.

[0073] As a preferred embodiment, in the embodiment, as shown in Figure 3 and Figure 6 As shown in FIG. 2 and FIG. 3, the gun body 201 is provided with a plurality of communication holes 2013 arranged at intervals along the circumferential direction of the gun body 201, and the communication holes 2013 communicate the glue outlet passage 100 and the annular passage 200. By communicating the glue outlet passage 100 and the annular passage 200 through the plurality of communication holes 2013, the efficiency of glue flowing into the glue outlet passage 100 is improved, and the glue can be supplied from multiple angles when entering the glue outlet passage 100. Compared with the communication mode of a single inlet, the glue can be more evenly distributed in the glue outlet passage 100, avoiding the situation that the glue is too much or too little in a local area due to a single glue supply point.

[0074] In specific implementation, the plurality of communication holes 2013 are arranged at equal angles, which is beneficial to further improve the uniformity of glue flowing into the communication holes 2013. Of course, the number of communication holes 2013 can be adjusted according to the use requirements. Further, the diameter of the communication holes 2013 gradually increases along the direction of the axis of the glue outlet passage 100, which is beneficial to improve the flowing effect of the glue. In addition, through the cooperation of the plurality of communication holes 2013, the uniformity of the glue is also improved, so that the uniform glue can flow out more smoothly from the glue nozzle 203, and the thickness of the glue applied is more uniform and consistent, reducing the glue application defects caused by uneven distribution of the glue, such as local over-thickness or under-thickness.

[0075] Furthermore, during the glue transmission process, when the glue passes through the communication holes 2013 from the annular channel 200 to the glue outlet channel 100, the pressure is dispersed at multiple communication holes 2013 instead of being concentrated at a single connection point. In this way, the pressure that the connection part of the gun body 201 and the annular channel 200 can bear is reduced, and the stability of the entire structure during the glue transmission process is enhanced.

[0076] In this embodiment, the driving part is rotatably provided with a mounting frame 8, and the mounting frame 8 is provided with a plurality of visual detection parts 9 arranged around the glue gun 2, which are used to detect the glue strip 1101 sprayed by the glue nozzle 203. By rotatably arranging the mounting frame 8 on the driving part, the mounting frame 8 can rotate relative to the driving part, thereby facilitating the angle adjustment of the plurality of visual detection parts 9. The plurality of visual detection parts 9 are cooperatively arranged to facilitate observation of the glue strip 1101 from different angles, thereby obtaining information of the glue strip 1101, and further facilitating detection of the quality of the glue strip 1101.

[0077] In this embodiment, the plurality of visual detection parts 9 are arranged around the glue gun 2, which can detect the glue strip 1101 sprayed by the glue nozzle 203 from multiple different angles. Compared with the single-angle detection method, this multi-angle observation can more comprehensively capture various characteristics of the glue strip 1101, reduce detection errors caused by limited viewing angles, and greatly improve the accuracy of the detection results.

[0078] In addition, each visual detection part 9 can detect different details of the glue strip 1101, such as accurately measuring the width and thickness of the glue strip 1101, and timely discovering whether the glue strip 1101 has local thinning or thickening, or has discontinuous problems such as breakpoints. Through such fine detection, the glue application quality can be better guaranteed, and the uniformity and integrity of the glue application can be ensured.

[0079] Further, in this embodiment, the visual detection part 9 can monitor the glue strip 1101 sprayed by the glue nozzle 203 in real time. During the glue application process, once any abnormality (such as irregular shape, sudden change in width, etc.) of the glue strip 1101 occurs, these information can be immediately fed back to the operator or the relevant control system. According to the information fed back by the visual detection part 9, the operator can timely adjust the glue application operation of the glue gun 2, such as adjusting the glue outlet speed, the action of the blocking member 4, etc. to change the glue application state of the glue nozzle 203.

[0080] In this embodiment, the visual detection part 9 can be flexibly adjusted according to different gluing scenes by rotating the mounting frame 8 on the driving part. For example, when gluing a complex-shaped object, it may be necessary to detect the adhesive tape 1101 from a specific angle. At this time, the visual detection part 9 can be rotated by rotating the mounting frame 8 to meet the detection needs in different scenes. In this way, the gluing device has good applicability in different gluing tasks and working environments.

[0081] As shown in Figures 1 to 3 The end of the glue gun 2 connected to the driving part is sleeved with a bearing, and the mounting frame 8 includes a base 801 and a bearing seat connected to the base 801 through a connecting column 802. The visual detection part 9 is arranged on the base 801, and the connecting column 802 extends along the length direction of the glue gun 2. The bearing seat is connected to the outer ring of the bearing. Among them, the end of the glue gun 2 connected to the driving part is sleeved with a bearing, and the bearing plays a connecting and supporting role, so that the glue gun 2 can be relatively flexibly rotated or other relative motion while being connected to the driving part. It also makes the visual detection part 9 and the glue gun 2 move relatively independently, which is beneficial to the visual detection part 9 to detect the entire adhesive tape 1101, thereby further improving the detection accuracy.

[0082] Specifically, for the convenience of description, the bearing between the glue gun 2 and the driving part is called the second bearing 5, and the bearing seat in the mounting frame 8 is called the second bearing seat 803. Among them, the second bearing 5 is installed on the second bearing seat 803, and the second bearing 5 is sleeved outside the top part 2012. The bottom cover 105 is located at the top of the top part 2012, and the bearing cover 501 located at the top of the second bearing 5 is sleeved outside the bottom cover 105. The bearing cover 501 is connected with the second bearing 5, which is used to limit the upward displacement of the top part 2012.

[0083] The connecting column 802 in this embodiment is a plurality of columns arranged along the circumference of the second bearing seat 803. Corresponding to each connecting column 802, a through hole is arranged on the edge of the second bearing seat 803 corresponding to each connecting column 802. The bottom end of the connecting column 802 is connected to the base 801, and the top end penetrates through the corresponding through hole and is screwed with the nut. With the tightening of the nut, the glue gun 2 and the mounting frame 8 can be fixed.

[0084] Among them, in this embodiment, the connecting column 802 extends along the length direction of the glue gun 2, which is beneficial to the connection of the base 801 and the bearing seat, so that the mounting frame 8 can establish an indirect connection relationship with the glue gun 2 through the bearing. The visual detection part 9 is arranged on the base 801, and is closely connected with the glue gun 2, the driving part and other components through the connecting column 802 and the bearing seat. Therefore, when the entire gluing device is gluing and detecting, each component can work cooperatively without interfering with each other, thereby improving the reliability and working efficiency of the entire device.

[0085] Due to the flexible rotation of the mounting frame 8, the visual detection part 9 can obtain the best observation angle to detect the rubber strip 1101. In different rubber coating scenarios, by adjusting the rotation angle of the mounting frame 8, the visual detection part 9 can be detected from the most favorable angle for observing the rubber strip 1101, so as to more accurately capture various features of the rubber strip 1101, such as shape, width, thickness, etc., thereby improving the accuracy and fineness of detection.

[0086] As a feasible implementation, the visual detection part 9 in the embodiment can adopt a 3D vision collector in the prior art, which includes two line lasers 901 arranged at the bottom end of the base 801, the two line lasers 901 are oppositely arranged at the two opposite sides of the nozzle and are arranged towards the outlet of the nozzle. The working principle is that when the line laser 901 irradiates on the rubber strip 1101 to form a contour, the 3D vision collector observes these laser-illuminated rubber strip 1101 contours from different angles. By known information such as the position, angle and parallax of the rubber strip 1101 contour in the image under two different viewing angles, the three-dimensional coordinates of each point on the surface of the rubber strip 1101 are calculated by using the mathematical model of triangulation, so as to completely obtain the three-dimensional data of the shape of the rubber strip 1101. As another feasible implementation, the visual detection part 9 can also adopt an industrial camera, which is also conducive to realizing the visual collection of the rubber strip 1101 by cooperating with the light source.

[0087] In addition, in order to further improve the opening and closing effect of the sealing piece 4 on the glue nozzle 203, as shown in Figure 8 The glue nozzle 203 includes a body part 2031 and a seat part 2032 arranged at the top end of the body part 2031, and the seat part 2032 is inserted at the bottom end of the glue outlet channel 100. The seat part 2032 has a matching channel 300 arranged through the circumference thereof, and the glue outlet channel 100 is in communication with the body part 2031 through the matching channel 300. The bottom end of the sealing piece 4 is arc-shaped and is specifically inserted into the top end of the matching channel 300. By sealing the top end of the matching channel 300, the opening or sealing of the glue nozzle 203 is realized.

[0088] Wherein, in order to facilitate the replacement and maintenance of the seat part 2032 and the body part 2031, the two are detachably installed at the bottom of the channel. Specifically, the bottom end of the seat part 2032 is provided with a radially outwardly protruding lower flange 2033, and the top end of the body part 2031 is provided with a radially outwardly protruding upper flange 2034. The lower flange 2033 is located between the upper flange 2034 and the bottom end of the main body part 2011. Further, a second lock nut 2035 is sleeved on the body part 2031, and the second lock nut 2035 is connected with the outer peripheral wall at the bottom end of the body part 2031 by screwing, so that the body part 2031 and the seat part 2032 of the glue nozzle 203 are fixed at the bottom end of the main body part 2011, thereby limiting the displacement of the glue nozzle 203 in the axial direction thereof. Further, two third sealing rings 2036 are arranged in an upper and lower spaced manner between the seat part 2032 and the inner peripheral wall of the glue outlet channel 100, so as to improve the sealing effect between the seat part and the glue outlet channel 100.

[0089] The glue coating device of the embodiment is used to start coating glue. The glue enters the annular channel 200 through the glue pipe 3. The flow monitoring part monitors the flow and bubbles of the glue. If there are bubbles in the glue, an alarm is given. The glue flows into the glue outlet channel 100 and the glue nozzle 203 through the communication hole 2013, and is coated on the workpiece through the glue nozzle 203. The 3D vision collects the outer dimensions of the glue strip 1101 through two line lasers 901, and checks the dimensions. If the dimensions are unqualified, an alarm is given.

[0090] As shown in FIG. 11B, Figure 9 When coated on the workpiece 11, the cross section of the glue strip 1101 is triangular. The laser lines (dashed lines in the figure) emitted by the two line lasers 901 correspond to the two sides of the glue strip 1101, so as to realize the detection of the quality of the glue strip 1101.

[0091] The glue coating device of the embodiment optimizes the structure for opening and closing the glue nozzle 203, especially through the cooperation of the driving part and the plugging member 4, so that the plugging member 4 plugs the glue nozzle 203 under the driving of the driving part, and the precise control of glue outlet can be realized. When it is necessary to stop coating glue, the plugging member 4 can quickly plug the glue nozzle 203, so as to avoid unnecessary outflow of glue and reduce waste.

[0092] Further, the glue pipe 3 is connected with the external glue supply device, so as to ensure the stable supply of glue. The external glue supply device can provide different types and viscosities of glue according to actual needs, so as to meet different glue coating needs. The connection mode of the glue pipe 3 makes the glue coating device more flexible, and the glue coating device can be arranged and adjusted according to the actual working environment. Furthermore, the structure design of the whole glue coating device is compact, and the driving part, the glue gun 2, the plugging member 4 and the glue pipe 3 cooperate with each other, so as to be compact in structure and small in space occupation.

[0093] In addition, the glue coating device of the embodiment also integrates the visual detection part 9 and the flow detection part 6, so that the quality problem caused by the unqualified glue size of the glue coating can be avoided, and the qualified rate of the glue is improved.
