Description
Technical Field
[0001] This utility model relates to the field of dispensing technology, and more specifically, to a dispensing cleaning and testing device. Background Technology
[0002] In the dispensing and mounting processes, dispensing machines are usually used for dispensing. However, after each dispensing, some glue remains in the needle (dispensing head), which affects the weight of subsequent dispensing. At the same time, dripping and leakage of glue can easily contaminate the product and affect the dispensing performance.
[0003] Currently, after cleaning the dispensing head, a needle tool is needed to clean the dispensing hole. However, due to the small diameter of the dispensing hole, it is difficult to monitor whether the dispensing head is clean. Utility Model Content
[0004] The purpose of this invention is to provide a dispensing cleaning and testing device that can effectively detect the cleanliness of the dispensing head and avoid adverse effects caused by glue residue on the dispensing head.
[0005] The embodiments of this utility model are implemented as follows: This utility model embodiment provides a dispensing cleaning and detection device, including: Base; A hose mounting base is fixedly mounted on the side wall of the base, and a mounting hole is provided through the bottom side of the hose mounting base. The bottom side of the mounting hole is used to install the dispensing head, and the top side of the mounting hole is used to install the hose. An active light source is slidably disposed on the side wall of the base and can selectively extend into or out of the mounting hole. When extended into the mounting hole, the light source emits light toward the dispensing aperture on the dispensing head to detect the cleanliness of the dispensing aperture.
[0006] In an optional embodiment, there are two hose mounting seats, which are spaced apart on the side wall of the base. The movable light source is located between the two hose mounting seats and one of them extends into the two mounting holes.
[0007] In an optional embodiment, the sidewall of the base is provided with a groove, the groove being located between the two hose mounting seats and extending from one hose mounting seat to the other hose mounting seat, the movable light source being slidably disposed in the groove and capable of moving along the groove.
[0008] In an optional embodiment, the active light source includes a sliding block, a light-emitting plate, and LED beads. One end of the sliding block is connected to the light-emitting plate, and the other end is slidably fitted in the slide groove to drive the light-emitting plate to move along the slide groove. The LED beads are disposed on the bottom side of the light-emitting plate and are used to extend into the mounting hole and emit light towards the dispensing through hole under the drive of the light-emitting plate.
[0009] In an optional embodiment, there are two LED beads, the sliding block is connected to the middle of the light-emitting plate, and the two LED beads are disposed at both ends of the light-emitting plate for extending into the two mounting holes respectively.
[0010] In an optional implementation, the lamp beads include LED lamp beads.
[0011] In an optional embodiment, the two hose mounting bases are provided with a first clearance hole on their opposite sidewalls, which communicates with the mounting hole. The shape of the first clearance hole is adapted to the shape of the light-emitting plate and the lamp bead, and is used to avoid the light-emitting plate and the lamp bead, so that the light-emitting plate and the lamp bead can extend into the mounting hole through the first clearance hole.
[0012] In an optional embodiment, each of the hose mounting bases is further provided with a second clearance hole on the side away from the first clearance hole, which communicates with the mounting hole. The shape of the second clearance hole is adapted to the shape of the light-emitting plate to allow the end of the light-emitting plate to pass through the hose mounting base.
[0013] In an optional embodiment, the groove is provided with a sliding shaft extending in the same direction, and the sliding block is slidably sleeved on the sliding shaft.
[0014] In an optional embodiment, a locking boss is further provided in the mounting hole, which is used to fix the dispensing head.
[0015] The beneficial effects of this utility model embodiment include: The dispensing cleaning and testing device provided in this embodiment of the invention has a dispensing tube mounting base fixedly installed on the side wall of the base. The mounting base has a mounting hole; the bottom side of the mounting hole is used to mount the dispensing head, and the top side is used to mount the dispensing tube, thus enabling the placement and fixing of the dispensing tube and the dispensing head. A movable light source is slidably mounted on the side wall of the base and can selectively extend into or out of the mounting hole. When the movable light source is extended into the mounting hole, it emits light towards the dispensing aperture on the dispensing head, thereby detecting the cleanliness of the dispensing aperture. In actual testing, the dispensing tube and the dispensing head can be cleaned first, and the cleaned dispensing head can be placed on the dispensing tube mounting base. Then, the movable light source is extended into the mounting hole and emits light, at which point the light transmittance of the dispensing head can be observed. If the dispensing orifice is clean, its light transmittance is good, allowing light to pass through. Conversely, if the orifice is poorly clean, its light transmittance is poor, significantly reducing the ability of light to pass through. The cleanliness of the dispensing head can be determined by observing the light transmittance of the orifice. After the test, the adhesive tube can be installed, completing the assembly of the tube and the dispensing head, and enabling the dispensing action. Compared to existing technologies, this embodiment of the invention can detect the cleanliness of the dispensing head by measuring the light transmittance of the orifice, effectively preventing adhesive residue from causing adverse effects.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] As disclosed in the background section, existing dispensing mechanisms typically require cleaning after dispensing. After rinsing the dispensing head, a cleaning needle is used to unclog and clean the dispensing orifices. However, it is currently difficult to detect whether the dispensing head is thoroughly cleaned, resulting in incomplete cleaning and potential glue residue that can cause adverse effects.
[0026] To address the aforementioned problems, this utility model provides a novel dispensing cleaning and testing device. The structure and working principle of this dispensing cleaning and testing device will be described in detail below.
[0027] See Figures 1 to 6 This utility model provides a dispensing cleaning and detection device 100, which can effectively detect the cleanliness of the dispensing head 200 and avoid adverse effects caused by glue residue on the dispensing head 200.
[0028] The dispensing cleaning and testing device 100 provided in this embodiment of the present invention includes a base 110, a tube mounting base 130, and a movable light source 150. The tube mounting base 130 is fixedly disposed on the side wall of the base 110, and a mounting hole 131 is provided through the bottom side of the tube mounting base 130. The bottom side of the mounting hole 131 is used to install the dispensing head 200, and the top side of the mounting hole 131 is used to install the tube 300. The movable light source 150 is slidably disposed on the side wall of the base 110 and can selectively extend into or out of the mounting hole 131. When extended into the mounting hole 131, it emits light toward the dispensing through hole on the dispensing head 200 to detect the cleanliness of the dispensing through hole.
[0029] In this embodiment, the sidewall of the base 110 is arranged vertically, the tube mounting base 130 is fixed to the sidewall of the base 110, and the mounting hole 131 is open vertically, allowing the tube 300 to be installed on the top side of the mounting hole 131 and the dispensing head 200 to be installed on the bottom side of the mounting hole 131, with the tube 300 clamping the dispensing head 200. During cleanliness testing, the dispensing head 200 is first installed, and then the movable light source 150 is inserted into the mounting hole 131 and emits light towards the dispensing aperture of the dispensing head 200 to achieve the test. After the test is completed, the movable light source 150 can extend out of the mounting hole 131, and the tube 300 can be installed. Pressing down causes the tube 300 to clamp with the dispensing head 200, completing the assembly of the dispensing head 200 and the tube 300, enabling subsequent dispensing.
[0030] It should be noted that the cleanliness of the dispensing head 200 is detected here by the light-emitting characteristics of the active light source 150 and the light-transmitting characteristics of the dispensing aperture. Preferably, a detection plate can be set below the dispensing head 200, or the table surface of the machine can be used as the observation table. When the active light source 150 moves into the mounting hole 131 and emits light, if a clear light spot appears on the detection plate or observation table, it indicates that the dispensing aperture of the dispensing head 200 is clean. Conversely, if a blurry light spot, a low light spot brightness, or even no light spot appears on the detection plate or observation table, it indicates that the cleanliness of the dispensing aperture is poor and needs to be cleaned again.
[0031] In some embodiments, there are two hose mounting seats 130, which are spaced apart on the side wall of the base 110. A movable light source 150 is disposed between the two hose mounting seats 130 and extends into one of the two mounting holes 131. Specifically, the two hose mounting seats 130 can realize the cleanliness detection of the two dispensing heads 200, which is more efficient. At the same time, the movable light source 150 is disposed between the two hose mounting seats 130, which can quickly switch between the two mounting holes 131.
[0032] In some embodiments, the sidewall of the base 110 is provided with a groove 111, which is located between two hose mounting seats 130 and extends from one hose mounting seat 130 to the other. The movable light source 150 is slidably disposed in the groove 111 and can move along the groove 111. Specifically, the groove 111 extends horizontally, and the movable light source 150 can move along the groove 111, thereby moving from the mounting hole 131 of one hose mounting seat 130 to the mounting hole 131 of the other hose mounting seat 130. The groove 111 ensures smoother and more precise movement.
[0033] In some embodiments, the active light source 150 includes a sliding block 151, a light-emitting plate 153, and LED beads 155. One end of the sliding block 151 is connected to the light-emitting plate 153, and the other end is slidably fitted in a groove 111 to drive the light-emitting plate 153 to move along the groove 111. The LED beads 155 are disposed on the bottom side of the light-emitting plate 153 and are used to extend into the mounting hole 131 and emit light towards the dispensing through hole under the action of the light-emitting plate 153. Specifically, a PCB board can be disposed on the light-emitting plate 153, and the LED beads 155 are disposed on the bottom surface of the light-emitting plate 153 and powered by the PCB board. The power supply can be achieved by connecting to an external power source through wires, or by adding a battery to the light-emitting plate 153 or the sliding block 151. The power supply method can refer to the existing LED bead 155 power supply method.
[0034] Furthermore, there are two LED beads 155. The sliding block 151 is connected to the middle of the light-emitting plate 153, and the two LED beads 155 are located at both ends of the light-emitting plate 153, respectively extending into the two mounting holes 131. Specifically, the two LED beads 155 are distributed at both ends of the light-emitting plate 153, so that they can respectively extend into the two mounting holes 131 to illuminate two different dispensing heads 200. During the sliding process of the sliding plate, the LED beads 155 on the left and right sides do not need to switch positions, which can achieve the change of position of the LED beads 155 more quickly and accurately.
[0035] Preferably, the lamp bead 155 includes an LED lamp bead 155. Here, the lamp bead 155 can be an LED lamp bead 155, which has high luminous efficiency and high brightness. Of course, in other preferred embodiments of this utility model, the lamp bead 155 can also be other types such as fluorescent lamps, and no specific limitation is made here.
[0036] In some embodiments, the two tube mounting bases 130 have a first clearance hole 133 on their opposite sidewalls, which communicates with the mounting hole 131. The shape of the first clearance hole 133 is adapted to the shape of the light-emitting plate 153 and the lamp bead 155, and is used to avoid the light-emitting plate 153 and the lamp bead 155 so that the light-emitting plate 153 and the lamp bead 155 can extend into the mounting hole 131 through the first clearance hole 133. Specifically, the first clearance hole 133 is rectangular, and its size is slightly larger than the shape of the light-emitting plate 153 and the lamp bead 155, so that the end of the light-emitting plate 153 and the lamp bead 155 can just pass through the first clearance hole 133 and enter the mounting hole 131. At the same time, the size of the first clearance hole 133 should not be too large. An excessively large first clearance hole 133 will cause more serious light leakage and affect the judgment of the light transmittance of the dispensing through hole. By setting the first clearance hole 133, the light-emitting plate 153 and the lamp bead 155 can be accurately inserted into the predetermined position of the mounting hole 131, and excessive light leakage can be avoided.
[0037] Furthermore, each hose mounting base 130 is provided with a second clearance hole 135 on the side away from the first clearance hole 133, which connects to the mounting hole 131. The shape of the second clearance hole 135 is adapted to the shape of the light-emitting plate 153, and is used to allow the end of the light-emitting plate 153 to pass through the hose mounting base 130. Specifically, the shape of the second clearance hole 135 is slightly larger than the end shape of the light-emitting plate 153, so that the end of the light-emitting plate 153 can be inserted into the second clearance hole 135, ensuring that the lamp bead 155 is installed in place in the mounting hole 131. The first clearance hole 133 and the second clearance hole 135 are on the same horizontal plane, which ensures that the light-emitting plate 153 is always in a horizontal position.
[0038] In some embodiments, a sliding shaft 137 extending in the same direction is provided in the groove 111, and a sliding block 151 is slidably sleeved on the sliding shaft 137. Specifically, the sliding shaft 137 is fixedly disposed in the groove 111, and both ends of the sliding shaft 137 are respectively connected to the two end walls of the groove 111. The sliding block 151 can be slidably sleeved on the sliding shaft 137 to ensure the sliding effect.
[0039] In some embodiments, a locking boss 139 is further provided in the mounting hole 131, which is used to fix the dispensing head 200. Specifically, the locking boss 139 is annular, and the position of the locking boss is lower than the position of the first clearance hole 133 and the second clearance hole 135. The locking boss 139 can be fixedly locked on the dispensing head 200, so that the dispensing head 200 can be fixed during testing. After testing, the glue tube 300 can be pressed on the dispensing head 200 to achieve assembly.
[0040] It should be noted that during actual dispensing, the base 110 can be driven to perform the dispensing action at the same time. That is, the glue tube 300 and the dispensing head 200 are directly assembled on the glue tube mounting base 130 and the subsequent dispensing action is performed.
[0041] In summary, the dispensing cleaning and testing device 100 provided in this embodiment of the present invention has a tube mounting base 130 fixedly installed on the side wall of the base 110. The tube mounting base 130 has a mounting hole 131. The bottom side of the mounting hole 131 is used to install the dispensing head 200, and the top side is used to install the tube 300, thus enabling the tube 300 and the dispensing head 200 to be placed and fixed. A movable light source 150 is slidably disposed on the side wall of the base 110 and can selectively extend into or out of the mounting hole 131. When the movable light source 150 is extended into the mounting hole 131, it emits light towards the dispensing aperture on the dispensing head 200, thereby detecting the cleanliness of the dispensing aperture. In actual testing, the tube 300 and the dispensing head 200 can be cleaned first. After cleaning, the dispensing head 200 is installed on the tube 300 mounting base, and the movable light source 150 is extended into the mounting hole 131 and emits light. At this time, the light transmittance of the dispensing head 200 can be observed. If the dispensing orifice is clean, its light transmittance is good, and light can pass through it; if the dispensing orifice is poorly clean, its light transmittance is poor, and the ability of light to pass through it is greatly reduced. The cleanliness level can be detected by observing the light transmittance of the dispensing orifice, thus completing the detection of the cleanliness level of the dispensing head 200. Compared with the prior art, this embodiment of the invention can detect the cleanliness level by detecting the light transmittance of the dispensing orifice, effectively detecting the cleanliness level of the dispensing head 200 and avoiding adverse effects caused by glue residue on the dispensing head 200.
[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
