Description

Technical Field

[0001] This utility model relates to the field of dispensing structure technology, and in particular to a dispensing device for applying adhesive. Background Technology

[0002] A dispensing machine is a device that applies adhesives to the surface or interior of a product. Before dispensing and after a certain period of operation, the dispensing head needs to be cleaned, currently using a wiping device. Existing wiping devices use two drive components to move wiping paper, clamping the dispensing head between the wiping paper for cleaning. However, these devices are often bulky and have multiple structures. After cleaning, the dispensing machine needs to perform a dotting test using a dotting device. This involves the dispensing head applying a small amount of adhesive to dotting paper; if the adhesive meets the requirements, normal dispensing can then proceed. Because the wiping device is large, the dotting and wiping devices cannot be installed in the same location, requiring the dispensing head to be moved a considerable distance after cleaning for the dotting test, resulting in low overall dispensing efficiency. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a glue application device that can reduce the distance between the cleaning position and the application position, thereby improving the glue application efficiency.

The protrusion can abut against the bottom of the groove, and the first elastic member is located in the groove.

[0006] In one embodiment of the present invention, the first conveying mechanism includes a first feeding wheel, a receiving wheel, and a second driving member. The first feeding wheel and the receiving wheel are both rotatably connected to the first support plate. An adhesive tape is wound around the first feeding wheel, and one end of the adhesive tape away from the first feeding wheel is connected to the receiving wheel.

[0008] In one embodiment of the present invention, the adhesive application assembly further includes a receiving member and a connecting frame. The connecting frame is connected to the first support plate, the receiving member is engaged with the connecting frame, and the connecting frame and the second driving member are located on the same side of the first support plate.

[0009] In one embodiment of the present invention, the adhesive application assembly further includes at least two first driven rollers, the adhesive application strip is attached to the first driven rollers, and the top block and the pressure plate are located between two adjacent first driven rollers.

[0010] In one embodiment of this utility model, a pressing assembly is further included. The second conveying mechanism includes a third driving member, a second feeding wheel, a synchronous belt, and at least two second driven rollers. The dotted belt is wound around the second feeding wheel. The second feeding wheel and the second driven roller are both rotatably connected to the second support plate. The third driving member is connected to the second support plate. The output end of the third driving member is connected to a drive wheel. The synchronous belt is fitted onto the second driven roller and the drive wheel. The dotted belt is in contact with the second driven roller and is clamped between the pressing end of the pressing assembly and the second driven roller.

[0014] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0015] The adhesive application device of this invention uses a pressure plate and a top block to clamp the adhesive tape, so that the adhesive tape, which is in contact with the top block, forms a flat surface when subjected to force, thus preventing wrinkles in the adhesive tape. The top block is designed to deform elastically, allowing it to indent when the end of the dispensing head comes into contact with the adhesive tape, resulting in a larger contact area between the adhesive tape and the dispensing head. This ensures that the adhesive at the end of the dispensing head is cleaned effectively. Compared to a structure where two driving components move the adhesive paper to clean the dispensing head, the adhesive application device of this invention has fewer components and a smaller size. This allows the adhesive application component to be placed on one side of the dispensing component, reducing the distance between the cleaning position and the dispensing position and improving dispensing efficiency.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1 to 6As shown, this utility model discloses a glue-applying device, comprising: a glue-applying assembly 1, including a first conveying mechanism, a first support plate 11, a top block 191, a mounting base 19, and a glue-applying tape 121; the glue-applying tape 121 is wound around the working position of the first conveying mechanism, which is capable of conveying the glue-applying tape 121; the mounting base 19 is connected to the first support plate 11; the top block 191 is slidably connected to the mounting base 19, and the top block 191 is elastically deformable; the top block 191 abuts against the glue-applying tape 121; a base plate 192 is connected to the side of the mounting base 19 away from the glue-applying tape 121; a first elastic element 193 is provided between the top block 191 and the base plate 192; and a pressure band. Component 2 includes a first driving member 21 and a pressure plate 22. The first driving member 21 is connected to the first support plate 11, and the pressure plate 22 is connected to the output end of the first driving member 21. The pressure plate 22 includes an opening 23, which corresponds to the position of the top block 191. The wiping tape 121 is located between the top block 191 and the pressure plate 22. Dotting component 3 includes a second support plate 31, a second conveying mechanism, a tray 35, and a dotting tape 321. The dotting tape 321 is wound around the working position of the second conveying mechanism, which can convey the dotting tape 321. The tray 35 is connected to the second support plate 31, and the tray 35 abuts against the dotting tape 321.

[0028] In this embodiment, a glue-applying device is provided. A first conveying mechanism conveys a glue-applying tape 121. When the glue-applying head needs cleaning, it moves to the cleaning position, so that the glue-applying head comes into contact with the glue-applying tape 121 on the top block 191. At this time, the pressure plate 22 squeezes the glue-applying tape 121, the first elastic element 193 is compressed, and the glue-applying head moves so that the end of the glue-applying head rubs against the glue-applying tape 121, thereby cleaning the glue-applying head. After the glue-applying head is cleaned, it moves to the application position. After the glue-applying head applies glue to the application tape 321 on the support plate 35, the glue on the application tape 321 is detected by an external detection device. After the detection is passed, the glue-applying head starts the glue-applying operation. The clamping of the wiping tape 121 by the pressure plate 22 and the top block 191 causes the wiping tape 121, which is in contact with the top block 191, to form a flat surface when subjected to force, thus preventing wrinkles from forming on the wiping tape 121. The elastic deformation setting of the top block 191 allows the top block 191 to be recessed after the end of the dispensing head comes into contact with the wiping tape 121, resulting in a larger contact area between the wiping tape 121 and the dispensing head. This allows the adhesive at the end of the dispensing head to be cleaned effectively. Compared to a structure where two driving components drive the wiping paper to clean the dispensing head, the wiping and dotting device of this utility model has fewer components and a smaller size. This allows the wiping component 1 to be placed on one side of the dotting component 3, thereby reducing the distance between the cleaning position and the dotting position and improving the dispensing efficiency.

[0029] Reference Figure 2As shown, the adhesive application assembly 1 includes a first conveying mechanism, a first support plate 11, a top block 191, a mounting base 19, and an adhesive application belt 121. The adhesive application belt 121 is wound around the working position of the first conveying mechanism, which is capable of conveying the adhesive application belt 121. Specifically, the first conveying mechanism includes a first feeding wheel 12, a receiving wheel 13, and a second driving member 14. The second driving member 14 can be considered as a motor, and the adhesive application belt 121 can be considered as an adhesive application cloth. Both the first feeding wheel 12 and the receiving wheel 13 are rotatably connected to the first support plate 11. The adhesive application belt 121 is wound around the first feeding wheel 12, and one end of the adhesive application belt 121 away from the first feeding wheel 12 is connected to the receiving wheel 13. The second driving member 14 is connected to the first support plate 11, and the output end of the second driving member 14 is connected to the receiving wheel 13. After the dispensing head completes one cleaning cycle via the wiping tape 121, the second drive unit 14 can drive the take-up wheel 13 to rotate, causing the wiping tape 121 to wrap around the take-up wheel 13. At the same time, the first feed wheel 12 is rotated by the pulling of the wiping tape 121, which in turn drives the wiping tape 121 to move, so that the wiping tape 121 corresponding to the wiping position no longer has adhesive.

[0030] Reference Figures 3 to 5 As shown, the mounting base 19 is connected to the first support plate 11, and the mounting base 19, the first feeding wheel 12, and the receiving wheel 13 are all located on the same side of the first support plate 11. The bottom end of the first support plate 11 is fixed to the outside. The top block 191 is slidably connected to the mounting base 19, and the top block 191 can elastically deform. The top block 191 abuts against the wiping tape 121. The side of the mounting base 19 away from the wiping tape 121 is connected to the base plate 192. A first elastic element 193 is provided between the top block 191 and the base plate 192. Specifically, the first elastic element 193 can be regarded as a spring, and the top block 191 can be regarded as foam. The top block 191 can move in the vertical direction. The side of the mounting base 19 near the base plate 192 is provided with a groove 195. The top block 191 passes through the bottom of the groove 195 and is slidably connected to the mounting base 19. The first elastic member 193 abuts against the bottom of the top block 191. The top block 191 has a protrusion 194 at one end near the first elastic member 193, that is, the bottom end of the top block 191 has a protrusion 194. The protrusion 194 protrudes from the edge of the bottom end of the top block 191, so that the protrusion 194 can abut against the bottom of the groove 195, thereby limiting the extreme movement position of the top block 191 and preventing the top block 191 from detaching from the mounting base 19. The first elastic member 193 is located in the groove 195 and between the top block 191 and the bottom plate 192. The two ends of the first elastic member 193 abut against the bottom end of the top block 191 and the bottom plate 192, respectively. In another embodiment, the top block 191 no longer has the protrusion 194, and the bottom end of the top block 191 is glued to a mounting plate. The size of the mounting plate is larger than the size of the top block 191, and the mounting plate abuts against the first elastic member 193. The mounting plate can abut against the bottom of the groove 195, thereby avoiding the pressure applied by the first elastic member 193 to the top block 191, which would cause the top block 191 to deform.

[0031] The pressure tape assembly 2 includes a first driving member 21 and a pressure plate 22. The first driving member 21 can be considered as a linear driving member. The first driving member 21 is connected to the first support plate 11 through a first connecting plate 24. The pressure plate 22 is connected to the output end of the first driving member 21. The pressure plate 22 includes an opening 23, which corresponds to the position of the top block 191 in the vertical direction. The moving path of the wiping tape 121 is located between the top block 191 and the pressure plate 22, so that the wiping tape 121 can be clamped between the top block 191 and the pressure plate 22. The position on the wiping tape 121 corresponding to the opening 23 on the pressure plate 22 is the dispensing head cleaning position. The clamping of the wiping tape 121 by the pressure plate 22 and the top block 191, and the setting of the opening 23 on the pressure plate 22, make the wiping tape 121, which is in contact with the top block 191, form a flat surface after being subjected to force, thus avoiding wrinkles in the wiping tape 121. The elastic deformation setting of the top block 191 allows the top block 191 to be recessed after the end of the dispensing head abuts against the wiping tape 121, resulting in a larger contact area between the wiping tape 121 and the dispensing head, and the adhesive at the end of the dispensing head can be cleaned up.

[0032] The adhesive application assembly 1 also includes at least two first driven rollers 15. In this embodiment, there are two first driven rollers 15, which correspond to the feeding position of the first feeding wheel 12 and the receiving position of the receiving wheel 13, respectively. The adhesive application belt 121 is in contact with the first driven rollers 15, and the two first driven rollers 15 form the movement path of the adhesive application belt 121. The top block 191 and the pressure plate 22 are located between two adjacent first driven rollers 15, so that the adhesive application belt 121 can be located between the pressure plate 22 and the top block 191. Through the arrangement of the first driven rollers 15, the adhesive application belt 121 can be parallel to the top side of the pressure plate 22 and the top block 191, thereby improving the cleaning effect of the adhesive application head. Preferably, a grooved photoelectric sensor is also connected to the first support plate 11. The grooved photoelectric sensor is connected to the controller. The end of the first driven roller 15 is connected to a sensing element that cooperates with the grooved photoelectric sensor. The grooved photoelectric sensor can detect the number of rotations of the sensing element, thereby detecting the distance the wiping tape 121 has moved, and thus prompting the replacement of the first feeding roller 12 and the receiving roller 13 after the wiping tape 121 is used up. Preferably, a photoelectric sensor connected to the controller is also provided between the two first driven rollers 15. The photoelectric sensor is connected to the first support plate 11, and the detection end of the photoelectric sensor faces the movement path of the wiping tape 121, thereby detecting whether there is wiping tape 121 between the first driven rollers 15. The wiping assembly 1 also includes a tensioning roller 16 rotatably connected to the first support plate 11. The tensioning roller 16 is located close to the receiving roller 13. The wiping tape 121 is in contact with the tensioning roller 16, and the tensioning roller 16 can tension the wiping tape 121, thereby enabling the wiping tape 121 to move smoothly.

[0033] The first feeding roller 12, the receiving roller 13, the mounting base 19, and the first driving member 21 are all located on the side of the first support plate 11 away from the dotting assembly 3. The second driving member 14 is located on the opposite side of the receiving roller 13 on the first support plate 11, that is, the second driving member 14 is located on the side of the first support plate 11 closer to the dotting assembly 3. The output end of the second driving member 14 passes through the first support plate 11 and is connected to the receiving roller 13. The rotation axes of the first feeding roller 12 and the receiving roller 13 are parallel, and the rotation axis of the receiving roller 13 is perpendicular to the plane of the first support plate 11. That is, the first feeding roller 12 and the receiving roller 13 are both arranged parallel to the first support plate 11, thereby reducing the space occupied by the first support plate 11, the first feeding roller 12, and the receiving roller 13. The mounting base 19 and the first driving member 21 correspond vertically to the positions between the first feeding roller 12 and the receiving roller 13, thereby making full use of the mounting position of the first support plate 11 and reducing the overall volume of the adhesive application assembly 1 and the pressure belt assembly 2.

[0034] The adhesive application assembly 1 also includes a receiving member 18 and a connecting frame 17. The connecting frame 17 is connected to the first support plate 11, and the receiving member 18 is snapped into the connecting frame 17, thereby fixing the receiving member 18 and the connecting frame 17 relatively. The receiving member 18 is used to receive the test adhesive from the dispensing head and the adhesive dripping when the dispensing head is not in operation, thereby preventing adhesive contamination of the outside. The connecting frame 17 and the second driving member 14 are both located on the side of the first support plate 11 near the dotting assembly 3, so that the entire adhesive application assembly 1 is supported only by the first support plate 11, making full use of the installation area of ​​the first support plate 11 and making the overall volume of the adhesive application assembly 1 small.

[0035] Reference Figure 6 and Figure 7As shown, the dotting assembly 3 includes a second support plate 31, a second conveying mechanism, a tray 35, and a dotting belt 321. The dotting belt 321 is wound around the working position of the second conveying mechanism, which can convey the dotting belt 321. Specifically, the dotting belt 321 can be considered as thermal paper. The second conveying mechanism includes a third drive member 33, a second feed roller 32, a synchronous belt 39, and at least two second driven rollers 37. The dotting belt 321 is wound around the second feed roller 32, and both the second feed roller 32 and the second driven roller 37 are rotatably connected to the second support plate 31. The third drive member 33 can be considered as a motor. The third drive member 33 is connected to the second support plate 31, and the output end of the third drive member 33 is connected to a drive wheel 38. The synchronous belt 39 is fitted onto the second driven roller 37 and the drive wheel 38, so that the third drive member 33 can simultaneously drive the two second driven rollers 37 to rotate. The dotting belt 321 is in contact with the second driven roller 37, and the two driven rollers 37 form the movement path of the dotting belt 321. That is, after being output by the second feed wheel 32, the dotting belt 321 passes through the two driven rollers 37 in sequence. The support plate 35 is connected to the second support plate 31, and the support plate 35 is located between the two driven rollers 37. The top side of the support plate 35 can abut against the dotting belt 321, that is, the movement path of the dotting belt 321 passes through the top side of the support plate 35, and the position on the dotting belt 321 corresponding to the support plate 35 is the dotting position.

[0036] Reference Figures 6 to 8As shown, the adhesive application device also includes a pressure assembly 4, and the application strip 321 can be clamped between the pressure end of the pressure assembly 4 and the second driven roller 37. Specifically, the pressure assembly 4 includes a second elastic element 42, a connecting block 46, a movable block 43, a connecting rod 44, and a pressure roller 45. Two second support plates 31 are provided, and the two second support plates 31 and the first support plate 11 are parallel to each other. A support plate 35 is connected between the two second support plates 31. The two connecting blocks 46 are respectively connected to the top ends of the two second support plates 31. The movable block 43 is hinged between the two connecting blocks 46. The movable block 43 has receiving grooves on both sides near the connecting blocks 46, so that the top side of the movable block 43 is T-shaped. The pressure roller 45 is rotatably connected to the movable block 43 and is located in the receiving groove. The connecting rod 44 is connected to the end of the movable block 43 away from the support plate 35. The two connecting rods 44 extend towards the two connecting blocks 46 respectively. The two ends of the second elastic element 42 are respectively fixed to the connecting rod 44 and the second support plate 31. Specifically, the second elastic element 42 can be regarded as a tension spring. A second connecting plate 41 is connected to each of the two second support plates 31. A mounting block can be connected to the second connecting plate 41, and the mounting block has a through hole. Both ends of the second elastic element 42 are provided with collars. One collar of each second elastic element 42 is respectively fitted onto the two connecting rods 44, and the other collar of each second elastic element 42 is respectively fitted onto the two mounting blocks through the through holes, thereby fixing both ends of the second elastic element 42 to the connecting rod 44 and the second support plate 31. A limiting block is also provided at the end of the connecting rod 44 away from the movable block 43, thereby preventing the end of the second elastic element 42 from detaching from the connecting rod 44. The pressure roller 45 is the pressing end of the pressing assembly 4. The second elastic element 42 can apply pressure to the movable block 43, thereby causing the pressure roller 45 to apply pressure to the second driven roller 37. The dotting belt 321 is clamped between the pressure roller 45 and the second driven roller 37. The third drive element 33 drives the two second driven rollers 37 to rotate through the transmission of the synchronous belt 39. Since the dotting belt 321 is clamped between the pressure roller 45 and the second driven roller 37, the friction between the dotting belt 321 and the second driven roller 37 is increased, allowing the second driven roller 37 to drive the dotting belt 321 to move, while the pressure roller 45 rotates. By clamping the dotting belt 321 between the pressure roller 45 and the second driven roller 37, the dotting belt 321 between the second driven rollers 37 can remain parallel to the support plate 35, while avoiding wrinkles in the dotting belt 321 between the second driven rollers 37 and maintaining tension. After the dispensing head dispenses adhesive onto the dotting tape 321 and performs a test, the third drive component 33 drives the second driven roller 37 to rotate, thereby moving the dotting tape 321. Because the adhesive has a certain thickness, the second elastic element 42 allows the dotting tape 321 containing the adhesive to pass between the pressure roller 45 and the second driven roller 37. As the dotting tape 321 passes between the pressure roller 45 and the second driven roller 37, the second elastic element 42 extends. The dotting tape 321 containing the adhesive can be stored in an external waste container.By setting the pressing component 4, the dotting component 3 only needs the second feeding wheel 32 to complete the conveying of the dotting belt 321. There is no need to install a take-up wheel or other take-up structure on the second support plate 31, thereby reducing the overall volume of the dotting component 3.

[0037] The second feeding wheel 32 and the third driving component 33 are both located between the two second support plates 31. Two second driven rollers 37 pass through the two second support plates 31 and are rotatably connected to them, thus fully utilizing the space between the two second support plates 31. One of the second support plates 31 is located between the second feeding wheel 32 and the synchronous belt 39. Specifically, the synchronous belt 39 is located on the second support plate 31 furthest from the first support plate 11, and it is located on the side of the second support plate 31 furthest from the first support plate 11. This fully utilizes the installable area of ​​the second support plate 31, resulting in a smaller overall volume of the dotting assembly 3. The parallel arrangement of the first support plate 11 and the second support plate 31 ensures that the mechanisms and parts on the adhesive application assembly 1 and the dotting assembly 3 are arranged in the same direction, thereby improving the rationality of the installation of the mechanisms and parts on the adhesive application assembly 1 and the dotting assembly 3 and reducing the overall volume of the adhesive application and dotting device.

[0038] The tray 35 is also provided with two stops 36 arranged along the moving path of the dotting tape 321. The moving path of the dotting tape 321 is located between the two stops 36, that is, the two stops 36 form a moving channel for the dotting tape 321 to move, thereby preventing the dotting tape 321 from being misaligned with the tray 35. Specifically, the stops 36 are connected to the top ends of the two second support plates 31. The tray 35 is also provided with multiple adsorption holes 351, which are connected to an external vacuum source. The adsorption holes 351 allow the dotting tape 321 to adhere to the tray 35, thereby keeping the dotting tape 321 in a flat state. When the dispensing head dispenses adhesive onto the dotting tape 321, the external vacuum source is activated, causing the adsorption holes 351 to adsorb the dotting tape 321, thereby improving the accuracy of the detection of the adhesive on the dotting tape 321. The dotting assembly 3 also includes a guide roller 34 rotatably connected to the second support plate 31, the dotting tape 321 is attached to the guide roller 34, and the guide roller 34 is used to guide the dotting tape 321 containing the adhesive.

[0039] In use, the first conveying mechanism conveys the wiping tape 121. When the dispensing head needs cleaning, it moves to the cleaning position, so that the dispensing head abuts against the wiping tape 121 on the top block 191. At this time, the pressure plate 22 squeezes the wiping tape 121, the first elastic element 193 is compressed, and the dispensing head moves so that the end of the dispensing head rubs against the wiping tape 121, thereby cleaning the dispensing head. After the dispensing head is cleaned, it moves to the dotting position. After the dispensing head dispenses glue to the dotting tape 321 on the tray 35, the glue on the dotting tape 321 is detected by an external detection component. The external detection component can be regarded as a vision inspection system. After the detection is passed, the dispensing head starts dispensing.

[0040] This invention discloses a glue-applying device. The pressure plate 22 and the top block 191 clamp the glue-applying tape 121, causing the tape 121, which is in contact with the top block 191, to form a flat surface under force, preventing wrinkles. The top block 191 is elastically deformable, allowing it to indent when the end of the dispensing head comes into contact with the tape 121, resulting in a larger contact area and more thorough cleaning of the glue at the end of the dispensing head. Compared to a structure where two driving components move the glue-applying paper to clean the dispensing head, this invention has fewer components and a smaller size. This allows the glue-applying component 1 to be positioned on one side of the dispensing component 3, reducing the distance between the cleaning position and the dispensing position and improving dispensing efficiency.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
