Description

Technical Field

[0001] This utility model relates to the field of adhesive dispensing equipment technology, and in particular to an adhesive dispensing mechanism and an adhesive applicator. Background Technology

[0002] In existing industrial applications such as dispensing and coating, the performance of the glue supply mechanism directly affects the accuracy and efficiency of the operation. Traditional pneumatic glue supply devices suffer from insufficient accuracy due to their structural limitations, making them unsuitable for applications requiring high dispensing and coating volumes. Furthermore, these devices may experience unstable glue supply during prolonged continuous operation, impacting product quality and production efficiency. On the other hand, while servo screw-type glue supply mechanisms offer improved accuracy, their larger size and heavier weight limit their use in space-constrained or weight-sensitive applications, and increase energy consumption and maintenance costs. Therefore, currently available glue supply mechanisms on the market do not provide precise dispensing position control, resulting in lower dispensing accuracy and affecting the quality of the dispensed products.

[0039] This utility model proposes a glue-pushing mechanism.

[0040] Please see Figure 1 and Figure 2In one embodiment of this utility model, the glue-pushing mechanism includes a fixed frame 10, a drive assembly 20, a transmission assembly, and a glue-dispensing assembly 40. The drive assembly 20 includes a drive member 21 and a reducer. Both the drive member 21 and the reducer are fixed to the fixed frame 10, and the reducer is connected to the drive member 21 in a transmission manner. The transmission assembly is connected to the reducer in a transmission manner and is spaced apart from the drive member 21 so that the transmission assembly can move up and down relative to the reducer. The glue-dispensing assembly 40 is fixed to the fixed frame 10 and is connected to the transmission assembly in a transmission manner so that the transmission assembly drives the glue-dispensing assembly 40 to dispense glue.

[0041] In this embodiment, the drive component 21 is a motor. The drive component 21 is fixed to the top side of the reducer with bolts. The reducer is located on one side of the fixing frame 10 and is tightly connected to the fixing frame 10 with screws. The drive component 21 and the reducer are connected by gears. The transmission assembly is connected to the reducer by gears, located above the reducer, and spaced apart from the drive component 21. When the drive component 21 is started, the reducer begins to rotate. The rotation of the reducer drives the transmission assembly to rise and fall. The transmission assembly drives the glue dispensing assembly 40 through a transmission connection, so that the glue is evenly pushed out from the glue outlet, realizing automatic and precise glue dispensing.

[0042] Since the drive component 21 and the transmission assembly are respectively connected to the upper and lower sides of the reducer, the transmission assembly can move up and down directly through the reducer, making the entire dispensing mechanism compact and reducing its size. Simultaneously, the height of the transmission assembly can be adjusted as needed to accommodate different dispensing volumes. The operator can control the lifting height of the transmission assembly by controlling the rotation speed of the drive component 21, thereby controlling the dispensing volume of the dispensing assembly 40. Through the above design, the dispensing mechanism of this embodiment not only occupies less installation space but also improves dispensing accuracy, thereby enhancing the quality of the dispensing products.

[0043] In other embodiments, the drive unit 21 may be a rotary cylinder, which is connected to the reducer via a transmission.

[0044] In one implementation, please refer to Figure 1 and Figure 2 The reducer is a hollow rotating platform 22, which has a central mounting hole; the transmission assembly includes a transmission nut and a lead screw 30, with the transmission nut installed in the central mounting hole; the lead screw 30 is rotatably connected to the center position of the transmission nut and movably passes through the central mounting hole; the lead screw 30 is connected to the glue dispensing assembly 40; the hollow rotating platform 22 drives the transmission nut to rotate, so that the lead screw 30 drives the glue dispensing assembly 40 to dispense glue.

[0045] By setting a central mounting hole in the hollow rotating platform 22, the transmission nut is installed in the central mounting hole, thus connecting the hollow rotating platform 22 and the transmission nut. When the hollow rotating platform 22 drives the transmission nut to rotate, the lead screw 30 rotates accordingly to drive the glue dispensing component 40 to automatically dispense glue, improving the motion stability of the glue pushing mechanism and ensuring the rotation accuracy of the rotating platform, thereby improving the overall working efficiency and product quality of the glue pushing mechanism.

[0046] The lead screw 30 is rotatably connected to the center of the transmission nut and movably passes through the center mounting hole. This design allows the lead screw 30 to drive the glue dispensing assembly 40 more smoothly during rotation, effectively eliminating the problem of uneven glue dispensing caused by poor transmission, thereby improving glue dispensing efficiency and product quality.

[0047] Optionally, the fit between the transmission nut and the center mounting hole is an interference fit or a threaded connection to ensure transmission efficiency. The connection between the lead screw 30 and the transmission nut is a rotary connection, such as a key connection or a pin connection, to facilitate the rotational movement of the lead screw 30.

[0048] Optionally, the surface of the lead screw 30 may be treated with a special coating, such as a ceramic coating or a wear-resistant coating, to improve its wear resistance and extend its service life. The diameter, pitch, and other parameters of the lead screw 30 can be adjusted according to actual needs to achieve different lifting speeds and strokes.

[0049] In other embodiments, the speed reducer may also be a planetary gear reducer, a harmonic reducer, a gear reducer, or a worm gear reducer, etc.

[0050] In one implementation, please refer to Figure 1 and Figure 2 The adhesive pushing mechanism also includes a guide assembly 50, which is located on the fixed frame 10 and connected to the lead screw 30. The guide assembly 50 is used to guide the lead screw 30 to move axially along the hollow rotating platform 22.

[0051] Specifically, the fixed frame 10 is a stable support structure that can be installed on the worktable of a dispensing machine. The lead screw 30 can move axially on the hollow rotating platform 22 through its connection with the guide assembly 50. The guide assembly 50 can effectively reduce the vibration of the lead screw 30 during the dispensing process. This design enables the lead screw 30 to maintain a stable motion trajectory during the dispensing process, thereby improving the dispensing accuracy of the dispensing mechanism.

[0052] Optionally, the guide assembly 50 can be a sliding bearing or guide rail that cooperates with the guide shaft, or it can be a guide belt, guide rail and guide block that cooperate.

[0053] In one implementation, please refer to Figure 1 and Figure 2The guide assembly 50 includes a connecting plate 51, a linear bearing 52, and a guide rod 53. The connecting plate 51 is connected to the end of the lead screw 30 away from the dispensing assembly 40. The linear bearing 52 is fixed to the fixing frame 10 and is spaced apart from the connecting plate 51. One end of the guide rod 53 is connected to the end of the connecting plate 51 away from the lead screw 30, and the other end of the guide rod 53 is movably inserted through the linear bearing 52.

[0054] The linear bearing 52 is fixed on the fixed frame 10 and spaced apart from the connecting plate 51, so that the guide rod 53 can move through the linear bearing 52, effectively reducing the guide deviation caused by vibration during equipment operation and improving the motion accuracy and stability of the entire dispensing assembly 40.

[0055] In one implementation, please refer to Figure 1 and Figure 2 The adhesive pushing mechanism also includes a crash pad 60, which is fixed to the fixing frame 10 and spaced apart from the lead screw 30.

[0056] In this embodiment, the glue-pushing mechanism uses an anti-collision pad 60 between the lead screw 30 and the drive member 21. This design prevents damage to the glue-pushing mechanism due to impact during operation. Optionally, the anti-collision pad 60 is made of rubber or other elastic and impact-resistant materials, and is fixed by screws or clips to ensure its stability. The lead screw 30 and the anti-collision pad 60 are spaced apart, so that the anti-collision pad 60 can effectively absorb the impact force that may be generated by the glue-pushing action during the operation of the glue-pushing mechanism, thereby protecting the glue-pushing mechanism from damage.

[0057] When the glue-pushing mechanism needs to move forward, the drive unit 21 is activated, driving the lead screw 30 to rotate via the hollow rotating platform 22, thereby causing the glue-pushing head 43 of the glue-dispensing assembly 40 fixed on the lead screw 30 to move downward. Since the anti-collision pad 60 is spaced apart from the lead screw 30, even if the glue-pushing head 43 encounters resistance, the anti-collision pad 60 can still act as a buffer, preventing damage to the lead screw 30 and the glue-pushing head 43.

[0058] To accommodate the needs of different models, the design of the mounting bracket 10 has been adjusted. The shape of the mounting bracket 10 has been changed to L-shape to adapt to installation in narrow spaces. The anti-collision pad 60 is also fixed to the mounting bracket 10, but uses a lighter material, such as foam plastic, to reduce the overall weight.

[0059] In one implementation, please refer to Figure 1 and Figure 2The adhesive pushing mechanism also includes an origin sensor 70, which includes an origin sensor and an origin sensing plate. The origin sensor is located on the fixed frame 10 and is spaced apart from the lead screw 30. The origin sensing plate is located on the hollow rotating platform 22. The origin sensor and the origin sensing plate are connected to each other for detecting the angle of the hollow rotating platform 22.

[0060] By introducing the origin sensor 70, which includes an origin sensor and an origin sensing element, the angle detection accuracy and efficiency of the equipment are greatly improved. The origin sensor is mounted on the fixed frame 10 and spaced apart from the lead screw 30, enabling it to output a stable signal. The origin sensing element is mounted on the hollow rotating platform 22 and connected to the origin sensor signal, allowing it to accurately detect the angle of the hollow rotating platform 22. This technical feature directly improves the production line control accuracy, thereby eliminating output deviations caused by inaccurate angle control and improving product quality.

[0061] When the hollow rotating platform 22 rotates relative to the fixed frame 10, the origin sensor can sense the origin sensing plate to obtain the electrical signal of the angle of the hollow rotating platform 22. The origin sensing plate is set at a preset angle of the hollow rotating platform 22. After the origin sensor and the origin sensing plate exchange electrical signals, the control drive 21 stops moving so that the hollow rotating platform 22 will not rotate excessively, thereby avoiding the excessive downward movement of the glue dispensing assembly 40's glue pushing head 43.

[0062] In one implementation, please refer to Figure 1 and Figure 2 The glue-pushing mechanism also includes a limit sensor 80, which includes a limit sensor and a limit sensor plate. The limit sensor is located at the end of the lead screw 30 away from the glue dispensing assembly 40, and the limit sensor plate is located on the fixed frame 10 and spaced apart from the lead screw 30. The limit sensor and the limit sensor plate are connected to each other for signal detection of the lifting distance of the lead screw 30.

[0063] On the one hand, the limit sensor 80 can detect the lifting distance of the lead screw 30 in real time, avoiding problems such as unstable glue dispensing and uneven glue pushing caused by the uncontrollable lifting distance of the lead screw 30 in the existing technology. By precisely controlling the position of the lead screw 30, the glue pushing accuracy is significantly improved, thereby enhancing the overall quality of the product.

[0064] On the other hand, the limit sensor is located at the end of the lead screw 30 away from the dispensing assembly 40 and is connected to the limit sensor plate. It can accurately capture the movement limit of the lead screw 30, effectively prevent equipment damage caused by excessive lifting and lowering of the lead screw 30, extend the service life of the equipment, and reduce maintenance costs.

[0065] In one implementation, please refer to Figure 1 and Figure 2The dispensing assembly 40 includes an installation cylinder 41, a glue tube 42, and a dispensing head 43. The installation cylinder 41 is fixed to the fixing frame 10. The glue tube 42 is fixed inside the installation cylinder 41, and the end of the glue tube 42 facing away from the transmission assembly has a glue outlet. The dispensing head 43 is movably connected inside the glue tube 42, and the dispensing head 43 is connected to one end of the transmission assembly. The transmission assembly drives the dispensing head 43 to rise and fall in the glue tube 42, so that the dispensing head 43 pushes glue inside the glue tube 42.

[0066] The mounting cylinder 41 is fixed to the fixing frame 10 by a fixing component, and is used to support and fix the glue tube 42. The lead screw 30 of the transmission assembly drives the glue-pushing head 43 to rise and fall inside the glue tube 42, so as to push the glue with the glue-pushing head 43 inside the glue tube 42. When the drive unit 21 is turned on, the transmission assembly starts to work, and the lead screw 30 of the transmission assembly drives the glue-pushing head 43 to descend inside the glue tube 42, pushing the glue out from the glue outlet. When the glue-pushing head 43 descends to a certain position, the motor is turned off, and the glue-pushing head 43 stops descending. Then the control lead screw 30 drives the glue-pushing head 43 to rise, and the glue in the glue tube 42 is re-drawn in, preparing for the next glue dispensing.

[0067] Optionally, the mounting cylinder 41 is connected to the fixing bracket 10 via a threaded structure to ensure stable and reliable installation. The adhesive tube 42 is made of transparent material to allow observation of the remaining adhesive level. A sealing ring is provided between the adhesive tube 42 and the mounting cylinder 41 to prevent adhesive leakage. The adhesive pushing head 43 is made of elastic material, allowing it to adapt to changes in the inner diameter of the adhesive tube 42 during adhesive pushing, ensuring uniform adhesive dispensing.

[0068] Optionally, the drive assembly 20 also includes a planetary reducer, which is connected to the drive component 21. The output shaft of the planetary reducer is connected to the lead screw 30, and the lead screw 30 is connected to the glue-pushing head 43 through the planetary reducer, enabling precise lifting and lowering of the glue-pushing head 43 within the glue tube 42. By controlling the pulse count of the drive component 21, the glue-pushing head 43 can be positioned at any location within the glue tube 42, improving glue dispensing accuracy.

[0069] In one implementation, please refer to Figure 1 and Figure 2 The mounting cylinder 41 includes two cylindrical shells 411, a hinge 412, and a quick-release component 413. The hinge 412 connects the two cylindrical shells 411 so that one of the cylindrical shells 411 is hinged to the other cylindrical shell 411. The quick-release component 413 is fixed to one of the cylindrical shells 411 and is detachably connected to the other cylindrical shell 411. The two cylindrical shells 411 enclose an inner cavity, and the rubber tube 42 is fixed in the inner cavity.

[0070] The two cylindrical shells 411 are made of suitable materials such as metal or plastic, possessing a certain strength and corrosion resistance. A hinge 412 connects the two cylindrical shells 411, allowing one shell 411 to rotate relative to the other. The hinge 412 is located on the side of the two cylindrical shells 411. The connection via the hinge 412 allows the two cylindrical shells 411 to be easily unfolded and folded, facilitating installation and disassembly.

[0071] A quick-release element 413 is fixed to one cylindrical shell 411 and detachably connected to another cylindrical shell 411. The quick-release element 413 can be a snap-fit, bolt, or other quick-connect device. The quick-release element 413 is located at the end of one cylindrical shell 411 and mates with a corresponding part of the other cylindrical shell 411. The quick-release element 413 allows for quick connection and separation of the two cylindrical shells 411, improving installation efficiency. A hose 42 is fixed within the inner cavity for fluid transport. The hose 42 can be fixed using adhesive, clamps, or bolts to ensure its stability within the inner cavity.

[0072] Optionally, the two cylindrical shells 411 can be designed in the shape of a circle, square, or ellipse to suit the needs of different occasions. The elliptical shape of the two cylindrical shells 411 helps to reduce the volume of the mounting cylinder 41 and improve space utilization.

[0073] This utility model also proposes a dispensing machine, which includes a base and a dispensing mechanism. The dispensing mechanism is disposed on the base and is used to dispense adhesive.
