Description

Technical Field

[0001] The utility model relates to the field of gluing machinery, in particular to a flanging detection structure and a gluing machine. Background Art

[0002] When existing gluing machines transport products (such as folded edge parts) on a transfer cart, there is a risk of material flipping when the material falls at the gluing position. If the material flips, gluing will begin without detection, which will cause product waste and the risk of machine collision, thereby increasing costs. Ordinary detection sensors currently available on the market cannot accurately detect and can only detect whether there is material, but cannot detect whether the material has flipped. There is currently no relevant detection technology for detecting whether the folded edge parts are flipped, and it can only rely on manual inspection to check whether the material has flipped, which is unreliable. Summary of the Invention

[0003] In order to solve the technical problem in the prior art that the gluing machine cannot accurately identify whether the folding position of the gluing position is flipped, the present application proposes a flanging detection structure and a gluing machine to solve the above technical problem.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The utility model provides a flanging detection structure, comprising: an optical fiber sensor, which is arranged on the side of the folding piece on the gluing station, and the light emitted by the optical fiber sensor's own light source is emitted to the folding piece and reflected back, and the optical fiber sensor receives the reflected light and converts the optical signal into an electrical signal and feeds it back to an amplifier; an amplifier, which is electrically connected to the optical fiber sensor, and after receiving the electrical signal fed back by the optical fiber sensor, the amplifier converts it into an instantaneous light receiving amount and uploads it to a host computer for comparison with a standard light receiving amount to determine whether the folding piece is flipped.

[0006] Furthermore, it also includes: a connecting sheet metal, which is screwed to the frame on the side of the folding piece on the gluing station, and a vertical mounting surface is formed on the connecting sheet metal near the side of the folding piece; a sensor angle adjustment plate, which includes a connecting piece and a mounting piece that are perpendicular to each other, the connecting piece is vertically configured and detachably connected to the mounting surface of the connecting sheet metal, and the downward bottom surface of the mounting piece is used to install the optical fiber sensor.

[0007] Furthermore, a circular connecting hole and a waist-shaped hole with the center of the connecting hole as the rotation point are formed on the connecting plate of the sensor angle adjustment plate. Bolts are arranged in the connecting hole and the waist-shaped hole to connect to the mounting surface of the connecting sheet metal. The angle of the mounting plate is adjusted by adjusting the position of the bolt in the waist-shaped hole.

[0008] Furthermore, the angle between the mounting plate and the horizontal direction is twenty-five degrees.

[0009] Another aspect of the present invention provides a gluing machine, comprising two gluing stations, wherein two of the above-mentioned flanging detection structures are disposed between the two gluing stations, and the optical fiber sensors of the two flanging detection structures are symmetrically arranged.

[0010] Based on the above technical solution, the technical effects that can be achieved by the present invention are:

[0011] The flanging detection structure of the present invention is configured with a fiber optic sensor on the side of the folding piece on the gluing station. The light emitted by the fiber optic sensor's own light source is emitted to the folding piece and reflected back. The fiber optic sensor receives the reflected light and converts the light signal into an electrical signal and feeds it back to the amplifier. After the amplifier receives the electrical signal fed back by the fiber optic sensor, it converts it into an instantaneous amount of light received and uploads it to the host computer for comparison with the standard amount of light received. The difference in the amount of light received can be used to determine whether the folding piece is flipped, thereby solving the technical problem in the prior art that the gluing machine cannot accurately identify whether the folding piece on the gluing position is flipped.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1-3As shown, the present invention provides a flanging detection structure, including an optical fiber sensor 1 and an amplifier 2. The optical fiber sensor 1 is arranged on the side of the folding piece 100 on the gluing station. The light source of the optical fiber sensor 1 emits light to the folding piece 100 and reflects back. The optical fiber sensor 1 receives the reflected light and converts the light signal into an electrical signal and feeds it back to the amplifier 2. The amplifier 2 is electrically connected to the optical fiber sensor 1. After receiving the electrical signal fed back by the optical fiber sensor 1, the amplifier 2 converts it into an instantaneous light receiving amount and uploads it to the host computer for comparison with the standard light receiving amount to determine whether the folding piece 100 is flipped. For example, Figure 1 The standard light receiving value of the folding member 100 in the normal state is 90. Figure 2 The light receiving value of the folding member 100 in the flipped state is 210. Figure 3 The light receiving value of the folding edge piece 100 shown in the figure is 35 when it is in an inverted state with the triangular opening facing downward.

[0018] In a specific embodiment of the present invention, the flanging detection structure also includes a connecting sheet metal 3 and a sensor angle adjustment plate 4. The connecting sheet metal 3 is screwed to the frame on the side of the folding piece 100 on the gluing station. The connecting sheet metal 3 is formed with a vertical mounting surface 31 near the side of the folding piece 100. The sensor angle adjustment plate 4 includes a connecting piece 42 and a mounting piece 41 that are perpendicular to each other. The connecting piece 42 is vertically configured and detachably connected to the mounting surface 31 of the connecting sheet metal 3. The mounting piece 41 is used to install the optical fiber sensor 1 on the bottom surface facing downward. The significance of installing the optical fiber sensor 1 on the bottom surface facing downward of the mounting piece 41 is that glue will fall on the gluing station, and the mounting piece 41 can be used to block the glue.

[0019] In a specific embodiment of the present invention, a circular connecting hole 421 and a waist-shaped hole 422 with the center of the connecting hole 421 as the rotation point are formed on the connecting plate 42 of the sensor angle adjustment plate 4. Bolts are arranged in the connecting hole 421 and the waist-shaped hole 422 to connect to the mounting surface 31 of the connecting sheet metal 3. The angle of the mounting plate 41 is adjusted by adjusting the position of the bolt in the waist-shaped hole 422.

[0020] In a specific embodiment of the present invention, the angle between the mounting piece 41 and the horizontal direction is 25 degrees to obtain better detection accuracy.

[0021] like Figure 1-3 As shown, another aspect of the present invention further provides a gluing machine, comprising two gluing stations, with two of the above-mentioned flanging detection structures arranged between the two gluing stations, the optical fiber sensors 1 of the two flanging detection structures being arranged symmetrically, and the amplifier 2 being able to be clipped onto the card strip of the gluing machine.

[0022] It should be understood that the specific embodiments described above are only used to explain the present invention and are not intended to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
