Description

Technical Field

[0001] This utility model relates to the field of glue applicator technology, specifically to an alarm device for a solventless glue applicator in a composite workshop. Background Technology

[0002] A glue applicator is an automated device that controls and applies adhesives and other coatings to the surface of a product. Its main working principle is to use compressed air to feed the coating into the glue supply pipe, and then, through program control, apply the coating to the corresponding glue rollers along a pre-set path to meet the needs of subsequent processing.

[0003] However, when using a single-component glue applicator in combination with a glue roller mechanism, there is a lack of technical means to sense the amount of glue between the glue rollers. Therefore, once the glue is used up, it is necessary to manually stop the glue applicator on the single-component glue applicator to avoid the glue rollers running out of glue or bursting. This increases the number of steps for machine operators and also increases the defect rate caused by operators forgetting to operate the machine. Utility Model Content

[0004] This invention provides an alarm device for a solventless glue applicator in a composite workshop, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an alarm device for a solventless glue applicator in a composite workshop, comprising a frame, two glue rollers aligned vertically are internally mounted on one side of the frame, an alarm and a composite support are respectively mounted on the top and inner wall of the frame, and an industrial camera is mounted in the middle of one side of the composite support. Pressure testing mechanisms are provided at the top and bottom of the composite support, and the inner side of the middle of the pressure testing mechanism can be fitted with the end of the corresponding glue roller and arranged along the central axis, and the detection end inside the pressure testing mechanism can be in contact with the end surface of the corresponding glue roller.

[0006] Preferably, the industrial camera is electrically connected to an image recognition device, and the image recognition device includes a processor, a model inference module, and a data transmission module. The processor is electrically connected to an alarm via a wire, so that after the industrial camera detects and outputs that there is no glue on the surface of the corresponding rubber roller, the alarm is triggered.

[0007] Preferably, the industrial camera is located between two rubber rollers, and the shooting range of the industrial camera can cover the end surface of the rubber rollers. The housing surface of the industrial camera is fixedly sleeved with the middle structure on one side of the composite support.

The surface of the second semicircular ring plate has a second arc-shaped groove, and a limiting block fixedly fitted inside the first arc-shaped groove is engaged at one end of the second arc-shaped groove.

[0009] Preferably, the interior of the second semicircular ring plate has a plurality of I-shaped holes arranged circumferentially along its own structure. A pressure detection component is fitted inside the I-shaped holes. The pressure detection component includes a pressure sensor, a cross-shaped detection rod, and a spring. One end of the pressure sensor and one end of the cross-shaped detection rod are respectively fixedly sleeved inside one end of the I-shaped hole and snapped into one end of the I-shaped hole. The other end of the cross-shaped detection rod serves as the detection end of the pressure detection mechanism, which can penetrate through the other end of the I-shaped hole and extend into the interior of the second semicircular ring plate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6An alarm device for a solventless glue applicator in a composite workshop includes a frame 1. Two glue rollers 2 aligned vertically are installed on one side of the frame 1. An alarm 6 and a composite support 3 are installed on the top and inner wall of the frame 1, respectively. An industrial camera 4 is installed in the middle of one side of the composite support 3. Pressure detection mechanisms 5 are provided at the top and bottom of the composite support 3. The inner side of the middle of the pressure detection mechanism 5 can be fitted with the end of the corresponding glue roller 2 and set with the central axis. The detection end inside the pressure detection mechanism 5 can be in contact with the end surface of the corresponding glue roller 2.

[0026] The industrial camera 4 is electrically connected to an image recognition device, which includes a processor, a model inference module, and a data transmission module. The processor is electrically connected to the alarm 6 via a wire. After the industrial camera 4 detects and outputs that there is no glue on the surface of the corresponding rubber roller 2, the alarm 6 will sound an alarm, thereby reminding the user that the glue on the rubber roller has run out, and promptly eliminating potential hazards in subsequent operations. The industrial camera 4 is located between two rubber rollers 2, and the shooting range of the industrial camera 4 can cover the end surface of the rubber roller 2, expanding its own working range. The housing surface of the industrial camera 4 is fixedly sleeved with the middle structure on one side of the composite support 3 to ensure its stability during continuous use.

[0027] The pressure testing mechanism 5 includes a first semicircular ring plate 51 and a second semicircular ring plate 52. The first semicircular ring plate 51 has a first arc-shaped groove 53 inside, and the second semicircular ring plate 52 can be housed or rotated out of the first semicircular ring plate 51 through the first arc-shaped groove 53. The surface of the second semicircular ring plate 52 has a second arc-shaped groove 54, and a limiting block 55, fixedly fitted into one end of the second arc-shaped groove 54, is engaged with it. A plurality of I-shaped holes 56 are arranged circumferentially along the interior of the second semicircular ring plate 52. Pressure testing components are fitted inside the I-shaped holes 56. The pressure testing components include a pressure sensor 57, a cross-shaped detection rod 59, and a spring 58. One end of the pressure sensor 57 is separated from one end of the cross-shaped detection rod 59. The spring 58 is fixedly sleeved inside one end of the I-shaped hole 56 and snapped into one end of the I-shaped hole 56. The other end of the cross-shaped detection rod 59 serves as the detection end of the pressure detection mechanism 5, which can penetrate through the other end of the I-shaped hole 56 and extend into the interior of the second semi-circular ring plate 52. The two ends of the spring 58 are respectively fixed to the inner wall of the other end of the I-shaped hole 56 and the surface of one end of the cross-shaped detection rod 59. In this way, multiple pressure detection components are used to detect the rotation trajectory of the corresponding rubber roller 2 in real time, promptly detect the deflection problem of the rubber roller 2, and reduce the subsequent defective product processing rate. The pressure sensor 57 is electrically connected to the pressure processor through a wire, and the pressure processor is electrically connected to the alarm 6 through a wire. When the pressure sensor 57 outputs a pressure data exceeding the preset pressure, the alarm 6 will sound an alarm.

[0028] During use, the following procedures are followed to detect whether there is glue coverage on the surface of the rubber roller 2 and to check its rotational deflection during the operation:

[0029] To detect whether there is glue coverage on the surface of the rubber roller 2, the industrial camera 4 will capture images of the surface of the rubber roller 2 in real time and transmit them to the image recognition device. The processor in the image recognition device will use the model reasoning module to determine whether there is glue coverage on the surface of the rubber roller 2 based on the appearance of the rubber roller 2 in the image, such as reflectivity, texture and color. When there is no glue coverage, the processor will alert the operator through the alarm 6 to replenish glue or stop the equipment in time to avoid the production of defective products.

[0030] For the rotational deviation of the rubber roller 2, multiple cross-shaped detection rods 59 inside the pressure detection mechanism 5 will press against the end of the rotating rubber roller 2. During the subsequent continuous rotation of the rubber roller 2, the cross-shaped detection rods 59 will be pressed synchronously and transmit the pressure to the pressure sensor 57, so that multiple pressure sensors 57 will send the corresponding pressure data to the pressure processor. When the output of a certain pressure sensor 57 exceeds the preset pressure data, it indicates that the rotation of the rubber roller 2 is abnormal. The pressure processor will warn the user through the alarm 6 and repair the equipment in time.

[0031] Please see Figures 3-6 A first mounting plate and a second mounting plate are respectively fixed to one end of the first semicircular ring plate 51 and one end of the second semicircular ring plate 52. The first mounting plate has a screw hole, and the second mounting plate has a countersunk hole aligned with the screw hole. The first mounting plate and the second mounting plate can be detachably installed by fitting screws into the countersunk hole and then threading them into the screw hole. There is clearance space between the composite support 3 and one end of the two rubber rollers 2, and the other side of the composite support 3 is detachably installed and fixed to the inner wall of the frame 1 by fasteners.

[0032] When in use, considering that both the industrial camera 4 and the pressure testing mechanism 5 contain electronic components that are prone to failure, when convenient maintenance is required, simply unscrew the screws between the first semicircular ring plate 51 and the second semicircular ring plate 52, and then flip the second semicircular ring plate 52 so that the second semicircular ring plate 52 rotates along the first arc groove 53 and is stored in the first semicircular ring plate 51 to make room. Similarly, the other pressure testing mechanism 5 can be operated in the same way. Then, unscrew the screws between the composite support 3 and the frame 1, and the composite support 3, the industrial camera 4 and the pressure testing mechanism 5 can be replaced and maintained in a modular manner.
