Description

Technical Field

[0001] The utility model relates to the technical field of composite machines, in particular to a paint missing detection and reminder device for a TPO composite machine. Background Art

[0002] After the TPO surface and sponge are bonded together on the TPO laminating machine, some products require a layer of adhesive to be applied to the sponge. This adhesive is then transferred to the adhesive printing wheel, supported by a rubber wheel. During normal production, if the printing wheel loses contact with the material due to product adjustments or abnormal opening of the rubber wheel, products that have not been coated with adhesive will undergo surface damage and marking. This defect is easily identified during winding and subsequent processes.

[0003] In addition to the fact that the rubber wheel fails to brush the back glue, there are also abnormalities such as changes in the gap between the printing wheel and the rubber wheel, and uneven glue brushing caused by insufficient glue in the glue tank, which makes it impossible to identify and form a mark.

[0004] Therefore, there is still a need for a TPO composite machine paint missing detection and reminder device to solve the above problems. Utility Model Content

[0005] The utility model provides a paint missing detection and reminder device for a TPO composite machine to solve the above problem.

[0006] The purpose of this utility model is achieved by the following technical solutions:

[0007] A TPO composite machine paint missing detection and reminder device, comprising:

[0008] A sponge discharge assembly is provided on the feeding rack and is used to supply the sponge layer in strips and finally convey it to the receiving roller;

[0009] A gluing assembly, comprising a gluing wheel and a receiving tank, both of which are connected to a feeding rack. The gluing wheel dips into the adhesive in the receiving tank while rolling and applies it to one side of the sponge layer before it is fed to a receiving roller.

[0010] The optical fiber sensor is arranged on the feeding rack and is used to identify the portion of the sponge layer that is not coated with adhesive.

[0011] In one embodiment, a warning light is further included, and the output end of the optical fiber sensor is electrically connected to the warning light.

[0012] In one embodiment, a marking device is further included. The marking device is arranged on the feeding rack and is electrically connected to the output end of the optical fiber sensor for marking the sponge layer.

[0013] In one embodiment, a dryer is further included, which is arranged between the sponge discharge assembly and the receiving roller and is used to dry the adhesive on one side of the sponge layer.

[0014] In one embodiment, a rubber wheel is further included, and the rubber wheel is used to cooperate with the upper rubber wheel to drive the sponge layer.

[0015] Compared with the prior art, the beneficial effects of the present invention include at least:

[0016] A fiber optic sensor with light sensing function is connected to the frame. The fiber optic sensor can be electrically connected to a warning light or identification device, or other reminder device. When the glue roller is short of glue, resulting in one side of the sponge layer not being coated with the corresponding adhesive, the fiber optic sensor determines whether the sponge layer passing by is coated with glue by irradiating the numerical range of light reflected on the sponge layer. The lightweight design is highly targeted, which improves the accuracy of judging the glue coating on the sponge layer, thereby improving the glue coating quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0020] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0021] Reference Figure 1 The utility model provides a TPO composite machine paint missing detection and reminder device, comprising:

[0022] The sponge discharge assembly is arranged on the feeding rack 9, and is used to supply the sponge layer in strips and finally convey it to the receiving roller; the sponge discharge assembly may include a material roller, wherein the rolled sponge layer is wound on the material roller.

[0023] The gluing assembly 1 includes a gluing wheel 2 and a receiving tank 3. Both the gluing wheel 2 and the receiving tank 3 are connected to a feeding rack 9. As the gluing wheel 2 rolls, it picks up the adhesive in the receiving tank 3 and applies it to one side of the sponge layer before it is fed to the receiving roller. Part of the outer contour of the gluing wheel 2 is located within the receiving tank 3, allowing the glue in the receiving tank 3 to be immersed and picked up. The receiving tank 3 can be formed, for example, in a glue box.

[0024] Fiber optic sensor 4, mounted on feed rack 9, is used to identify uncoated portions of the sponge layer. Fiber optic sensor 4 uses light to distinguish between glued and uncoated sponge surfaces, accurately identifying uncoated portions and prompting the operator to directly identify and mark the uncoated portions, facilitating subsequent direct location and removal of these portions.

[0025] In one embodiment, a warning light 5 is further included, and the output end of the optical fiber sensor 4 is electrically connected to the warning light 5. The warning light 5 can be electrically connected to the output end of the optical fiber sensor 4. When in operation, the output end of the optical fiber sensor 4 can output an electrical signal to control the warning light 5 to promptly alert the operator and make a mark in time to facilitate subsequent direct positioning and removal.

[0026] In one embodiment, a marking device 6 is further included. The marking device 6 is disposed on the feed rack 9 and electrically connected to the output end of the optical fiber sensor 4 for marking the sponge layer. The marking device 6 may include a cylinder and a pressure head assembly. When receiving an electrical signal from the optical fiber sensor 4, the cylinder drives the pressure head to create an indentation or perforation mark on the surface of the sponge, thereby completing automated marking.

[0027] In one embodiment, the apparatus further comprises a drying machine 7, which is arranged between the sponge discharge assembly and the receiving roller and is used to dry the adhesive on one side of the sponge layer. The drying machine 7 can dry the adhesive on the sponge, thereby facilitating storage.

[0028] In one embodiment, a rubber wheel 8 is further included, and the rubber wheel 8 is used to cooperate with the upper rubber wheel 2 to drive the sponge layer.
