Description

Technical Field

[0001] This invention belongs to the field of die-cutting technology, and in particular relates to a die-cutting device and method for multiple narrow rubber products. Background Technology

[0002] In the electronics industry, as the industry develops, many parts are becoming smaller and smaller, and the corresponding die-cut products are also becoming smaller and more diversified. In order to save assembly costs, customers often combine multiple die-cut parts together for production.

[0003] In response to this phenomenon, the industry has adopted a skip-production method. Although this production method has a simple process, the product defect rate is very high due to the excessively small gaps between products and the waste discharge.

[0004] Existing technologies for processing multi-narrow adhesive products include: Figure 1 As shown, the product's shape is first processed using a skip cutter to remove waste material between product gaps and the product surface membrane. Then, the product's handle membrane shape is processed, and finally, the product is glued together. However, when removing waste between multiple narrow adhesive strips, pulling can easily occur, causing the connecting material between the multiple narrow adhesive strips to break, resulting in product defects. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art by providing a die-cutting device and method for multiple narrow rubber products.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] The present invention provides a die-cutting device for multiple narrow rubber products, comprising a first feeding mechanism, a first die-cutting mechanism, a first waste removal mechanism, a second feeding mechanism, a second die-cutting mechanism, a second waste removal mechanism, a third feeding mechanism, a third die-cutting mechanism, a third waste removal mechanism, and a finished product winding mechanism arranged sequentially along the material strip traveling direction;

[0008] The first die-cutting mechanism is used to punch out multiple narrow plastic product outlines, the second die-cutting mechanism is used to punch out multiple narrow plastic joint product outlines, and the third die-cutting mechanism is used to punch out the handle touch product outline.

[0009] Furthermore, the first feeding mechanism includes a first feeding roller and a first feeding roller drive motor that is connected to the first feeding roller in a transmission manner. The first feeding mechanism feeds out the main material adhesive and the first cover film and forms a "main material adhesive-first cover film" composite layer structure from top to bottom.

[0010] Furthermore, the first die-cutting mechanism includes a first die that is matched with the plurality of narrow rubber products, and a first die drive motor that is connected to the first die in a transmission manner;

[0011] The first waste removal mechanism includes a first waste removal roller and a first waste removal roller drive motor that is connected to the first waste removal roller in a transmission manner. The first waste removal mechanism removes the contour waste generated after the first die-cutting mechanism has finished die-cutting.

[0012] Furthermore, the second feeding mechanism includes a second feeding roller and a second feeding roller drive motor that is connected to the second feeding roller in a transmission manner. The second feeding mechanism feeds out the connecting material adhesive and the second cover film, and forms a composite layer structure of "second cover film-connecting material adhesive-main material adhesive-first cover film" from top to bottom.

[0013] Furthermore, the second die-cutting mechanism includes a second die that is matched to the products at the multiple narrow glue joints, and a first die drive motor that is driven by the second die.

[0014] The second waste removal mechanism includes a second waste removal roller and a second waste removal roller drive motor that is connected to the second waste removal roller. The second waste removal mechanism removes the contour waste generated after the second die-cutting mechanism and makes the connecting material adhesive and the main material adhesive connected and kept flush. The second cover film and the first cover film are connected and kept flush.

[0015] Furthermore, the third feeding mechanism includes a third feeding roller and a third feeding roller drive motor that is connected to the third feeding roller. The third feeding mechanism feeds out the handle film and forms a composite layer structure of "handle film - connecting material adhesive and main material adhesive - second cover film and first cover film" from top to bottom.

[0016] Furthermore, the third die-cutting mechanism includes a third die for punching out the shape of the handle and a third die drive motor that is connected to the third die in a transmission manner.

[0017] Furthermore, the third waste removal mechanism includes a third waste removal roller and a third waste removal roller drive motor that is connected to the third waste removal roller in a transmission manner. The third waste removal mechanism removes the contour waste generated after the third die-cutting mechanism has finished die-cutting.

[0018] Furthermore, the finished product winding mechanism includes a finished product winding roller and a finished product winding drive motor that is drivenly connected to the finished product winding roller.

[0019] The present invention also provides a die-cutting method for a multi-narrow adhesive product die-cutting device, comprising the following steps:

[0020] S1, Primary material tape bonding: The main material adhesive and the first cover film are bonded together from top to bottom to form a primary material tape;

[0021] S2, One-time die cutting and waste removal: The primary strip is punched to cut out multiple narrow plastic product outlines, and the outline waste generated after punching is removed.

[0022] S3, Primary strip bonding: The connecting material adhesive, the second cover film and the primary strip punched in S2 are bonded together from top to bottom to form the secondary strip;

[0023] S4, two-stage die cutting and waste removal: the secondary strip is punched, and after punching, the connecting material adhesive and the main material adhesive are connected and kept flush, the second cover film and the first cover film are connected and kept flush, and then the contour waste generated after punching is removed.

[0024] S5, three-level material strip bonding: The handle film and the punched second-level material strip in S4 are bonded together from top to bottom to form a three-level material strip;

[0025] S6, Three-stage die-cutting waste removal: The three-stage strip is punched to cut out the outline of the handle film product, then the outline waste generated after punching is removed, and finally the product is wound up.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. This invention involves die-cutting multiple narrow rubber products into their shapes twice, and then removing waste material after each die-cutting. Compared with the traditional skip-cut processing mode, this effectively reduces the pulling of products caused by waste removal, reduces product defects caused by waste removal, and improves the productivity of multiple narrow rubber products.

[0028] 2. The multiple die-cutting method of this invention makes debugging more convenient. When using jump cutter die-cutting, product defects may require overall structural re-adjustment and replacement of all products. This invention only requires debugging of a single die-cutting mechanism or replacement of a single strip, which improves production efficiency and reduces production costs.

[0066] Example 2

[0067] This embodiment provides a die-cutting method for a multi-narrow adhesive product die-cutting device as described in Embodiment 1. (See also...) Figure 2 As shown, it includes the following steps:

[0068] S1, Primary material tape bonding: The main material adhesive 101 and the first cover film 102 are bonded together from top to bottom to form a primary material tape. Specifically, the first feeding mechanism 1 feeds out the main material adhesive 101 and the first cover film 102 and forms a composite layer structure of "main material adhesive 101-first cover film 102" from top to bottom. That is, the first feeding roller drive motor drives the first feeding roller to feed out the main material adhesive 101 and the first cover film 102, and the main material adhesive 101 and the first cover film 102 are bonded together to form a primary material tape under the rotation of the first feeding roller.

[0069] S2, First punch die cutting and waste removal: The primary strip is punched to cut out multiple narrow rubber product outlines, and the outline waste generated after punching is removed. Specifically, the first die cutting mechanism 2 punches out multiple narrow rubber product outlines, that is, the first die drive motor drives the first die to punch the primary strip of "main material rubber 101-first cover film 102". Then the first waste removal mechanism 3 removes the outline waste generated after the first die cutting mechanism 2, that is, the first waste roller drive motor drives the first waste roller to remove the waste between the two narrow rubber product outlines generated by punching the main material rubber 101.

[0070] S3, Primary strip bonding: The connecting material adhesive 401, the second cover film 402, and the primary strip cut in S2 are bonded together from top to bottom to form a secondary strip. Specifically, the second feeding mechanism 4 feeds out the connecting material adhesive 401 and the second cover film 402, and forms a secondary strip from top to bottom in the order of "second cover film 402-connecting material adhesive 401-main material adhesive 101-first cover film 102". That is, the second feeding roller drive motor drives the second feeding roller to feed out the connecting material adhesive 401 and the second cover film 402, and under the rotation of the second feeding roller, the second cover film 402 and the connecting material adhesive 401 are bonded together, and a secondary strip from top to bottom in the order of "second cover film 402-connecting material adhesive 401-main material adhesive 101-first cover film 102" is formed.

[0071] S4, Two-stage die-cutting and waste removal: The secondary strip is punched, and after punching, the connecting material 401 and the main material 101 are connected and kept flush, and the second cover film 402 and the first cover film 102 are connected and kept flush. Then, the contour waste generated after punching is removed. Specifically, after the second die-cutting mechanism 5 punches, the connecting material 401 and the main material 101 are connected and kept flush, and the second cover film 402 and the first cover film 102 are connected and kept flush, that is, the second die-cutting motor drives the second die-cutting to punch "the second cover film 402-connecting material". The composite layer structure of "connecting material adhesive 401-main material adhesive 101-first cover film 102" is formed by punching, so that the connecting material adhesive 401 is located between the two narrow adhesives of the main material adhesive 101 after punching. Then, the second waste removal mechanism 3 removes the contour waste generated after the second die-cutting mechanism 5. That is, the second waste roller drive motor drives the second waste roller to remove the contour waste generated after the second die-cutting mechanism 5, so that the connecting material adhesive 401 and the main material adhesive 101 are connected and kept flush, and the second cover film 402 and the first cover film 102 are connected and kept flush.

[0072] S5, Three-level material strip bonding: The handle film 401 and the punched secondary material strip in S4 are bonded together from top to bottom to form a three-level material strip. Specifically, the third feeding mechanism 7 feeds out the handle film 401 and forms a three-level material strip from top to bottom: "handle film 401 - connecting material adhesive 401 and main material adhesive 101 - second cover film 402 and first cover film 102". That is, the third feeding roller drive motor drives the third feeding roller to feed out the handle film 401, and the rotation of the third feeding roller causes the handle film 401 to bond with the punched secondary material strip to form a three-level material strip.

[0073] S6, Three-stage die-cutting and waste removal: The three-stage strip is punched to cut out the outline of the handle film product. Then, the waste material generated after punching is removed. Finally, the product is wound up. Specifically, the third die-cutting mechanism 8 punches out the outline of the handle film product, that is, the third die drive motor drives the third die to punch out the shape of the handle. The third waste removal mechanism 9 removes the waste material generated after the third die-cutting mechanism 8, that is, the third waste roller drive motor drives the third waste roller to remove the waste material of the handle outline. Finally, the finished product winding mechanism 10 winds up the die-cut composite layer structure, that is, the finished product winding roller drive motor drives the finished product winding roller to rotate so that the final product is wound up for later use.

[0074] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort.
