Description

Technical Field

[0001] This invention relates to the field of label technology, and in particular to a method for producing readable adhesive labels for automotive parts. Background Technology

[0002] Labels are common information identification stickers on the market. They have product information printed on their surface, such as manufacturer, production time, barcode, anti-counterfeiting barcode, etc. When making a purchase, this information will allow the buyer to understand the product directly, shortening the time to learn about the product. At the same time, labels are easy to use and can be applied by equipment or manually, and have a wide range of applications.

[0003] Chinese invention patent CN112844964B discloses a self-adhesive label manufacturing process, including the following steps: Step 1, cutting the fabric: cutting the fabric paper to prepare strips of fabric paper with uniform width; Step 2, applying adhesive: applying adhesive to the back of the strips of fabric paper prepared in Step 1; Step 3, pasting the fabric: cutting the strips of fabric with adhesive on the back to obtain circular fabric paper, pasting the cut circular fabric paper onto the base paper, and finally rolling up the base paper with the pasted circular fabric paper; wherein, Step 3 is completed using a self-adhesive label manufacturing device; and the process solves the technical problem of how to avoid wrinkles in the circular fabric sheet.

[0004] Chinese invention patent CN110316607A discloses a label production device and process. The label includes a release liner and a face sheet that can be peeled off and pasted onto the release liner. A non-adhesive strip that can be peeled off and pasted onto the face sheet is provided between the release liner and the face sheet. The production device includes a separating rod and an guiding rod arranged on the same side of the label conveying direction. The separating rod and the guiding rod are arranged sequentially back and forth in the label conveying direction. The working end of the separating rod is inserted between the release liner and the face sheet of the label to separate the sides of the release liner and the face sheet. The end of the guiding rod corresponding to the working end of the separating rod is inserted between the release liner and the face sheet of the label. A non-adhesive strip of a set width crosses the end of the guiding rod and enters between the release liner and the face sheet. This invention solves the technical problem of how to reduce edge wrinkles and difficulty in peeling during the peeling process.

[0005] The two patent documents disclosed above can solve the technical problem of label wrinkling, but their labeling methods are relatively traditional. During the labeling process, the air between the label and the component cannot be squeezed out, which can easily cause the label to bulge and affect the label information recognition effect. At the same time, the two labels disclosed above have weak adhesion and are easily scratched or peeled off by foreign objects, making them inconvenient to use. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems by providing a method for producing a readable adhesive label for automotive parts that can produce a label with strong adhesion and strong protection, and that can ensure flatness during application, avoiding label bulging and wrinkling, and satisfying the requirement of information readability on the label.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a method for producing readable adhesive labels for automotive parts, comprising the following steps: S1: label information is created and laid out; S2: label is printed and then laminated; S3: a deformable sheet is made below the label; S4: the bottom layer of the label is coated with adhesive and then bonded to the surface of the deformable sheet in S4 by a stamping mechanism; S5: adhesive is applied to the bottom of the deformable sheet; S6: the label in S5 is bonded to coated paper.

[0008] Preferably, step S2 includes the following steps: S201: After the label is printed, apply an adhesive layer to its upper and lower surfaces; S202: Cover both sides of the label with a film layer so that the film on both sides forms an integral part with the label; S203: Trim off the excess film layer around the label to obtain a label with a film layer size that matches the label for later use.

[0009] Preferably, in step S3, the deformable sheet includes a cover layer, a metal mesh, and a support layer. The metal mesh is disposed between the cover layer and the support layer. The surface of the support layer has a recess, and the metal mesh is disposed in the recess of the support layer. The cover layer and the support layer are fixed to the metal mesh inside by an adhesive bonding method. The cover layer and the support layer are elastic rubber layers. The cover layer and the support layer can be bent by the metal mesh. A label body is provided on the top of the deformable sheet.

[0010] Preferably, in step S4, the label bottom layer is applied with adhesive, i.e., the adhesive layer is applied to the outer side of the film layer. The stamping device includes an extrusion rod, a stamping plate, and a carrier box. The extrusion rod is driven by a robotic arm. The bottom surface of the stamping plate is provided with an arc-shaped pressure plate. The stamping plate and the arc-shaped pressure plate are provided with through holes. The top of the through holes is connected to an air suction pipe. The air suction pipe draws air and adsorbs the label body onto the surface of the arc-shaped pressure plate. The surface of the carrier box is provided with a groove. The bottom surface of the groove is an arc-shaped concave surface. The carrier box is a hollow structure and contains adhesive. The surface of the carrier box is provided with two opposing support rods. The two support rods contain a constantly rotating roller. One side of the roller is provided with an adhesive outlet pipe. The adhesive outlet pipe injects adhesive into the circumference of the roller.

[0011] Preferably, step S4 includes the following steps: S401: First, the deformable sheet is placed into the groove by a robotic arm; S402: The label body is moved to the roller by another robotic arm and a pressing rod, and the bottom surface of the label is coated with adhesive by rotating the roller; S403: After the bottom surface of the label is coated with adhesive, it is placed into the groove and pressed and bonded with the deformable sheet; S404: After the label and the deformable sheet are bonded together, adhesive is applied to the bottom surface of the deformable sheet; S405: After the bottom surface of the deformable sheet is coated with adhesive, the whole piece is picked up again by suction pipe and through hole.

[0012] Preferably, the arc-shaped concave surface is provided with multiple slots, and the carrier box sprays the internal colloid onto the bottom surface of the deformable sheet at the slots.

[0013] Preferably, the carrier boxes are multiple and evenly arranged on the conveyor belt, which is driven by a stepper motor.

[0015] Preferably, the metal wire used in the metal mesh is iron wire with a diameter of 0.2-0.5 mm.

[0016] Preferably, the label is further provided with a protective layer, the bottom surface of which has an assembly notch, and the perimeter of which has chamfers.

[0017] Compared with existing technologies, this production method for readable adhesive labels for automotive parts has the following advantages: 1. The label as a whole can be deformed through the internal covering layer, metal mesh, and carrier layer, ensuring flatness during adhesion and avoiding bulges or wrinkles between the automotive parts and the label, thus improving the label's readability; 2. The film coating around the label prevents wear and tear, protects the displayed information, and also provides moisture and water resistance, improving overall performance; 3. The label production process is simple and highly automated, ensuring label production quality while saving labor. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0023] Please refer to Figure 1-3 A method for producing readable adhesive labels for automotive parts, characterized by the following steps: S1: Label information creation and layout; S2: Label printing followed by lamination; Specific steps are as follows: S201: After printing the label, apply an adhesive layer to its top and bottom surfaces; S202: Cover both sides of the label body with the film layer, making the film on both sides integrated with the label, wherein the film layer is a transparent plastic film; S203: Trim the excess film layer around the label to obtain a label with a film layer size matching the label for later use; S3: Create a deformable sheet at the bottom of the label; S4: Apply adhesive to the bottom of the label and bond it to the surface of the deformable sheet in S4 using a stamping mechanism; S5: Apply adhesive to the bottom of the deformable sheet; S6: Bond the label from S5 to coated paper; wherein the surface of the coated paper has a silicone oil layer to prevent the bottom adhesive from remaining on the coated paper.

[0024] In step S3, the deformable sheet includes a cover layer 102, a metal mesh 103, and a support layer 104. The metal mesh 103 is disposed between the cover layer 102 and the support layer 104. The surface of the support layer 104 has a recess 105, and the metal mesh 103 is disposed in the recess of the support layer 104. The cover layer 102 and the support layer 104 are fixed to the metal mesh 103 by adhesive bonding. The cover layer 102 and the support layer 104 are elastic rubber layers with a thickness of 0.4-0.6 mm. The cover layer 102 and the support layer 104 can be bent by the metal mesh 103. A label body 101 is provided on the top of the deformable sheet.

[0025] In this invention, the length of the recess 105 is greater than the length of the metal mesh 103, which can provide a certain deformation space for the metal mesh when it is bent and deformed. The metal wire used in the metal mesh 103 is iron wire with a diameter of 0.2-0.5 mm, preferably 0.4 mm.

[0026] That is to say, after the label body 101 is bonded to the deformable piece, a complete label is formed. When the label is used on automotive parts, the pasting method includes the following steps: (1) Before pasting, bend the label downward to form an arc shape; (2) When pasting, first paste one end of the label onto the part; (3) Scrape the label in the direction of its upward movement by an object.

[0027] In step (3) above, the object is first placed on the adhesive end of the label. Since the label is arc-shaped, the other end will be raised. When scraping, scrape from one end to the other. During this process, the air between the parts and the label will be squeezed out to prevent the label from bulging and affecting information recognition. At the same time, when scraping, the label can be flattened and fully adhered, increasing the adhesive force.

[0028] In this invention, step S4 involves applying adhesive to the label's bottom layer, i.e., applying the adhesive layer to the outer side of the film layer. The stamping device includes an extrusion rod 9, a stamping plate 10, and a support box 2. The extrusion rod 9 is driven by a robotic arm. The bottom surface of the stamping plate 10 is provided with an arc-shaped pressure plate 12. The stamping plate 10 and the arc-shaped pressure plate 12 have through holes 11. The top of the through hole 11 is connected to an air suction pipe. Figure 2 Only the through hole is shown (the suction pipe connected to the through hole is not shown). The suction pipe draws air to adsorb the label body 101 onto the surface of the arc-shaped pressure plate 12. The surface of the carrier box 2 is provided with a groove 9, and the bottom surface of the groove 9 is an arc-shaped concave surface 7. The carrier box 2 is a hollow structure, and the inside is filled with colloid. The surface of the carrier box 2 is provided with two opposing support rods 3. The two support rods 3 are provided with a constantly rotating roller 4. One side of the roller 4 is provided with a glue outlet pipe 5. The glue outlet pipe 5 injects the colloid into the circumference of the roller 4. The carrier box 2 is also provided with a pump. The pump drives the colloid to spray from the glue outlet pipe 5 onto the roller 4.

[0029] Specifically, step S4 includes the following steps: S401: First, the deformable sheet is placed into the groove by a robotic arm; S402: The label body is moved to the roller by another robotic arm and a pressing rod, and the bottom surface of the label is coated with adhesive by rotating the roller; S403: After the bottom surface of the label body is coated with adhesive, it is placed into the groove and pressed and bonded with the deformable sheet; S404: After the label and the deformable sheet are bonded together, adhesive is applied to the bottom surface of the deformable sheet; S405: After the bottom surface of the deformable sheet is coated with adhesive, the whole piece is picked up again by the suction tube and the through hole; S406: After being picked up, it is pasted onto the coated paper.

[0030] The method for manufacturing the deformable piece in step S401 includes the following steps: S4011: First, the arc-shaped concave surface is placed in the groove using a robotic arm; S4012: The metal wire mesh is attracted by an electromagnet so that the metal wire mesh corresponds to the concave area on the support layer; S4013: After the magnetic force of the electromagnet disappears, the metal wire mesh falls into the concave area; S4104: The cover layer is covered onto the support layer again using a robotic arm, and the metal mesh is fixed inside by the cover layer and the cover layer.

[0031] Furthermore, to facilitate the spraying of adhesive onto the bottom surface of the deformable sheet, multiple slots 8 are provided on the arc-shaped concave surface 7. The carrier box 2 sprays the internal adhesive onto the bottom surface of the deformable sheet through the slots 8, which facilitates its adhesion to coated paper or automotive parts. Multiple carrier boxes 2 are evenly arranged on the conveyor belt 1, which is driven by a stepper motor. The rotation distance of the conveyor belt 1 is constant to meet the requirements of continuous label production.

[0032] Based on the above embodiments, the label is also provided with a transparent protective layer 106. The bottom surface of the protective layer 106 is provided with an assembly notch 107. After the label is pasted on the component, it is protected by the outer protective layer 106. During protection, the label (and the deformable piece) is inside the assembly notch. The protective layer 106 is provided with chamfers around its perimeter, which can prevent the label from being torn or scraped off, increase the adhesion, and at the same time prevent the label from being scratched.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
