Description

Technical Field

[0001] The present invention relates to the technical field of colloid curing detection, and specifically to a multi-point glue sample curing experiment detection system for UV glue. Background Technique

[0002] The photosensitive curing characteristics of UV glue can be applied to various products for practical use. UV glue can be used for insulation sealing and filling gaps. It can also be combined with ink to endow the ink with the characteristic of rapid curing. When UV glue is applied to continuous automated processing production, with a certain amount and volume of UV glue used for the same product, the following parameters mainly need to be considered: 1. The distance between the curing light source and the glue dot; 2. The length of the curing chamber; 3. The movement speed of the conveyor belt. The inspection standards for UV glue are: 1. Curing hardness; 2. Color fixation condition (for ink); 3. Surface curing state.

[0003] Under the condition that the inspection standards are fixed, if the control parameters under the qualified curing standards of this UV glue or UV ink can be obtained, it is beneficial to adjust the production line and provide multiple qualified reference standards for the control of the production line. For example, applying the qualified standards of increasing curing power, reducing the distance, and increasing the movement speed to rush jobs can ensure efficient and rapid processing. Applying the qualified standards of reducing curing power, keeping the distance unchanged, and reducing the movement speed to normal jobs can reduce energy cost losses and increase product profits.

[0004] Currently, the detection of UV glue is mainly hardness detection. Although hardness is one of the curing indicators of UV glue, the surface viscosity and decolorization of UV glue and UV ink cannot be detected. And these two parameters have a greater impact on the appearance. Summary of the Invention

DETAILED DESCRIPTION

[0027] See also Figures 1-6 In this embodiment, a conveyor belt 1 and an automatic glue dispensing machine 2 are included. The automatic glue dispensing machine 2 is arranged at the front end of the conveyor belt 1. A dynamic UV curing chamber 3, a glue point pressure adhesion monitoring module 4, and a glue point surface viscosity monitoring module 5 are sequentially arranged on the conveyor belt 1.

[0028] In this embodiment, the belt body of the conveyor belt 1 is a composite belt of a silicone belt and a toothed belt, the toothed belt cooperates with the gear and is driven by a servo motor to make the composite belt rotate. The automatic glue dispenser 2 drips UV glue or a mixture of UV glue and ink on the surface of the silicone belt in a quantitative manner, and moves with the silicone belt.

[0029] In this embodiment, the glue point first moves to the inside of the dynamic ultraviolet curing chamber 3. The dynamic ultraviolet curing chamber 3 includes a light-shielding chamber 31, a light-emitting plate 32, and a height adjuster 33. The light-emitting plate 32 is vertically slidably connected to the top of the light-shielding chamber 31 through the height adjuster 33 to adjust the irradiation height of the curing light source. The light-shielding chamber 31 surrounds the conveyor belt 1 to prevent other light from affecting the curing parameters. There are multiple matrix-distributed ultraviolet lamps on the light-emitting plate 32, and the power of the ultraviolet lamps can be adjusted. At the same time, different horizontal or vertical ultraviolet lamps can be independently controlled to open and close. The height adjuster 33 can control the up and down movement of the light-emitting plate 32 by electric push rods and screw transmission, in order to adjust the irradiation spacing. The purpose of the dynamic ultraviolet curing chamber 3 using the above components is to obtain multiple spacing parameters, power parameters, and quantity parameters on the basis of the qualified back end, and obtain a data group in combination with the speed parameter of the conveyor belt 1. Multiple data groups provide selection parameters for the regulation of the production line, which is more in line with actual production applications.

[0030] In this embodiment, the glue point pressure adhesion monitoring module 4 includes a first bracket 41, an image collector 42, a wiping roller 43, a contact wheel 44, and a reversing transmission 45. The contact wheel 44 is in contact with the conveyor belt 1, and the wiping roller 43 and the contact wheel 44 are connected by the reversing transmission 45. The wiping roller 43 and the contact wheel 44 rotate in opposite directions and are in contact with each other. The image collector 42 is vertically irradiated on the annular surface of the contact wheel 44.

[0031] In this embodiment, in order to detect the decolorization problem of the UV glue and ink mixture. When the conveyor belt 1 moves, the contact wheel 44 is always in contact with the conveyor belt 1. Therefore, the contact wheel 44 rotates relatively, and the direction-changing transmission 45 uses the gear cooperation to make the wiping roller 43 rotate in the opposite direction to the contact wheel 44, and the rotational linear velocity of the wiping roller 43 is less than that of the contact wheel 44. Thus, relative sliding always occurs between the contact wheel 44 and the wiping roller 43, and the contact surface between the wiping roller 43 and the contact wheel 44 gradually changes. This avoids the problem that the contact surface between the wiping roller 43 and the contact wheel 44 is in contact with the decolorized material for a long time, resulting in unmonitorable problems. After the glue dots pass through the wiping roller 43, the decolorized substances adhered to the surface of the wiping roller 43, and when the wiping roller 43 rotates to below the image collector 42, the stain image of the image collector 42 is collected by the computer and then the wiping roller 43 wipes and cleans it. When the dynamic ultraviolet curing chamber 3 and the conveyor belt 1 are adjusted to qualified parameters, the image collector 42 cannot collect color information. At this time, the control parameters of the conveyor belt 1 and the dynamic ultraviolet curing chamber 3 are recorded.

[0032] In this embodiment, in order to detect the surface viscosity problem of the UV glue and ink mixture. A problem that easily occurs after the UV glue and ink mixture is cured is that the whole does not decolorize, the internal curing degree is good, but the surface is relatively soft. At this time, when pressed by a finger, embossing is likely to occur, aiming at the problem that the ink printing is likely to cause the surface to become gelatinized and unclear.

[0033] In this embodiment, the surface viscosity monitoring module 5 of the glue dots includes a second bracket 51, an adhesion monitoring mechanism 52, an annular wheel 53, and a film-sealed hollow plate 54. The film-sealed hollow plates 54 are distributed at equal angles on the circumference of the annular wheel 53. The annular wheel 53 is rotatably connected to the second bracket 51. The adhesion monitoring mechanism 52 is used to monitor the change of the surface film when the film-sealed hollow plate 54 is separated from the sample. The arc surface of the annular wheel 53 is closed by a film, and the four sides of the film are surrounded by rigid frames. A communicating L-tube 55 is arranged at the bottom of the annular wheel 53. A balance piston 551 is slidably connected to one end of the communicating L-tube 55 close to the adhesion monitoring mechanism 52. A rangefinder 521 is fixedly connected to the adhesion monitoring mechanism 52.

[0034] In this embodiment, the annular wheel 53 contacts the conveyor belt 1 through the film-sealed hollow plate 54. The annular wheel 53 rotates as the conveyor belt 1 moves. The frame of the film-sealed hollow plate 54 contacts the conveyor belt 1, so the film will not be deformed, and the cavity inside the film-sealed hollow plate 54 will not be deformed. After the film-sealed hollow plate 54 contacts the colloid, if the colloid has viscosity, it will adhere to the film-sealed hollow plate 54 at this time. Please refer to Figure 6, when the film-sealed hollow plate 54 rotates, the film gradually separates from the colloid. At this time, the viscosity of the colloid will drive the film to stretch outward. The film is elastic. At this time, the volume of the internal cavity of the film-sealed hollow plate 54 increases. The connecting L-tube 55 is a pipeline, and the connecting L-tube 55 is connected to the film-sealed hollow plate 54. The film deforms, causing the balance piston 551 to move towards the side away from the adhesion monitoring mechanism 52. The distance measuring device 521 obtains the distance parameter from the balance piston 551, so as to judge the surface viscosity of the colloid based on the distance parameter. This method can detect the mixture of uv glue and ink, and can also detect uv glue alone due to the sealing and beautifying effect on uv glue. The balance piston 551 can be provided with a balancer to ensure balance. The balancer can be a combination of a spring and a tension spring, so that the balance piston 551 remains stable when the cavity of the film-sealed hollow plate 54 does not change.

[0035] In this embodiment, a shovel plate 7 is provided at one end of the conveyor belt 1 away from the dynamic ultraviolet curing chamber 3. The shovel plate 7 is tangent to and in contact with the arc surface of the conveyor belt 1.

[0036] In this embodiment, the whole process is repeated multiple times. The conveyor belt 1 is made of a silica gel belt. The hydrophobicity of silica gel makes it difficult for uv glue to adhere to the surface. Therefore, the shovel plate 7 can be located at the bend of the conveyor belt 1, causing the uv glue and the silica gel to form a cracking angle, and then the shovel plate 7 can remove the colloid.

[0037] In this embodiment, a lubricating medium spraying module 6 that cooperates with the shovel plate 7 is provided at one end of the conveyor belt 1 away from the dynamic ultraviolet curing chamber 3. A spraying pipe 61 is provided at the front end of the lubricating medium spraying module 6.

[0038] In this embodiment, in order to avoid excessive friction between the shovel plate 7 and the silica gel, the spraying pipe 61 can spray a lubricating medium to reduce the friction between the shovel plate 7 and the silica gel. A Teflon film can also be provided at the front end of the shovel plate 7 to ensure the minimum sliding resistance.

[0039] In this embodiment, the glue point pressure adhesion monitoring module 4, the glue point surface viscosity monitoring module 5, and the lubricating medium spraying module 6 are all installed at the support block 11 through the telescopic support module 8. The support block 11 is located between the belt bodies of the conveyor belt 1 to support the belt body.

[0040] In this embodiment, the glue point pressure adhesion monitoring module 4 and the glue point surface viscosity monitoring module 5 will exert forces on the conveyor belt 1. Therefore, the support block 11 can support the glue point pressure adhesion monitoring module 4 and the glue point surface viscosity monitoring module 5 to ensure stability, and can also provide a fixed fulcrum for the lubricating medium spraying module 6.

[0041] In this embodiment, the telescopic support module 8 is composed of a sleeve and a sliding rod. A tension spring is provided between the sleeve and the sliding rod, and a distance sensor is provided between the sleeve and the sliding rod.

[0042] In this embodiment, the telescopic support module 8 is arranged at the glue point pressure adhesion monitoring module 4 and the glue point surface viscosity monitoring module 5, which can ensure the contact between the wheel body and the conveyor belt 1, so as to complete the acquisition. When the telescopic support module 8 is arranged at the glue point pressure adhesion monitoring module 4, the tensile force of the tension spring can also be used to detect the telescopic change of the telescopic support module 8 after the colloid is pressed. The telescopic change of the telescopic support module 8 can reflect the deformation of the colloid and can also be used as the detection and judgment standard for the uv glue block.

[0043] In this embodiment, the acquisition information of the glue point pressure adhesion monitoring module 4 and the glue point surface viscosity monitoring module 5 is transmitted to the computer. The rotation speed of the conveyor belt 1, the lifting height of the height adjuster 33, and the number and power of the lights turned on by the light-emitting plate 32 are all controlled by the computer uniformly.

[0044] In this embodiment, during automatic control, when the parameters of the glue point pressure adhesion monitoring module 4 and the glue point surface viscosity monitoring module 5 are qualified, the control parameters of the conveyor belt 1 and the dynamic ultraviolet curing chamber 3 are recorded by the computer, and the parameters of the conveyor belt 1 and the dynamic ultraviolet curing chamber 3 are continuously adjusted until the adjustment reaches the highest value that meets the actual use and then stops, so as to obtain multiple qualified data sets.

[0045] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
