Description

Technical Field

[0001] The utility model relates to the technical field of a TPU hot melt adhesive film detection device, in particular to a TPU hot melt adhesive film detection device. Background Art

[0002] Hot melt adhesive film is widely used in the packaging industry for operations such as sealing boxes, bags and boxes. It can quickly and efficiently bond materials such as cardboard, paper, plastic film, etc., providing a strong closure and sealing effect.

[0003] Flatness testing is often important for hot melt adhesive film applications. Flatness refers to the flatness or surface flatness of the hot melt adhesive film when it is applied to the target surface. Flatness directly affects the contact area and quality between the hot melt adhesive film and the target surface. If the hot melt adhesive film is not attached to the target surface evenly, the contact area will be reduced, which will affect the firmness and durability of the bond.

[0004] In some application scenarios, the flatness of the hot melt adhesive film may be directly related to the functional performance of the product. For example, in the screen protector of electronic devices, if the hot melt adhesive film is not flat, it may cause the sensitivity of the touch screen to decrease or the optical display to be distorted.

[0005] Therefore, it is particularly important to detect the flatness of TPU hot melt adhesive film after production. The current detection method is profile measurement, which will have the following problems:

[0006] 1. TPU hot melt adhesive film usually has a certain degree of transparency, which may cause the penetration and scattering of light during the measurement process, affecting the accuracy of the measurement. Transparency will cause the measurement results to be interfered by the background or underlying materials.

[0007] 2. TPU hot melt adhesive film is usually soft and has a certain degree of deformation ability, which may cause the shape of the film to change during the measurement process, making the measurement results unstable or inaccurate. The softness of the film may cause it to deform or fluctuate on the surface during the measurement, resulting in errors in the measurement results.

[0008] Therefore, a TPU hot melt adhesive film detection device is urgently needed to detect the flatness of the TPU hot melt adhesive film. Utility Model Content

[0052] Please refer to Figure 1-Figure 4 An embodiment of the utility model provides a TPU hot melt adhesive film detection device. A TPU hot melt adhesive film detection device in this embodiment includes

[0053] According to one aspect of the utility model, a TPU hot melt adhesive film detection device is provided, and the TPU hot melt adhesive film detection device comprises:

[0054] A testing table 100, wherein the testing table 100 has a placement surface 100a, and the placement surface 100a is used to place the TPU hot melt adhesive film to be tested;

[0066] In at least one embodiment of the present application, the moving component 110 includes

[0076] In this embodiment, the first motor 112 rotates to drive the first screw rod 113 to move the movable assembly 114 in a direction parallel to the placement surface 100 a .

[0077] The movement of the movable component 114 drives the detection component 120 to rotate.

[0078] A plurality of detection balls 124 are arranged on the rolling element 121 of the detection assembly 120 , and the flatness of the TPU hot melt adhesive film to be detected placed on the placement surface 100 a is detected by rotating.

[0079] The detection ball 124 on the detection seat 123 is in contact with the pressure sensor 125 , and the pressure applied thereon by the detection ball 124 is monitored by the pressure sensor 125 .

[0081] Wherein, the accommodating groove is a semicircular groove.

[0082] In at least one embodiment of the present application, the placement surface 100a is provided with adsorption holes 100b;

[0083] The TPU hot melt adhesive film detection device also includes:

[0084] The suction member 130 is disposed on the detection platform 100 , and the suction member 130 is communicated with the adsorption hole 100 b .

[0094] In this embodiment, the suction member 130 and the suction holes 100b are used to absorb the hot melt adhesive film to ensure that it is firmly fixed on the placement surface 100a.

[0095] The fixing assembly 140 fixes the hot melt adhesive film through the abutment member 141 and the abutment rod 142 to provide stable support and positioning.

[0096] The elastic member 143 provides appropriate pressure to make the hot melt adhesive film contact with the detection component 120 and maintain a certain degree of close contact.

[0098] The presence of the elastic member 143 allows the device to adapt to hot melt adhesive films of different thicknesses and unevenness, and provides a certain elastic pressure to ensure good contact between the hot melt adhesive film and the detection component 120 .

[0099] Through the combined action of the abutting surface 100c, the fixing assembly 140 and the elastic member 143, the TPU hot melt adhesive film on the placement surface 100a can be stably fixed, and appropriate contact and pressure can be maintained to ensure accurate and reliable detection results.

[0100] principle:

[0101] The hot melt adhesive film is placed on the placement surface 100a, and then the two ends of the hot melt adhesive film are fixed on the placement surface 100a using the fixing assembly 140. At this time, the elastic member 143 provides appropriate pressure to make the hot melt adhesive film contact with the detection assembly 120 and maintain a certain degree of close contact.

[0102] The suction member 130 absorbs the hot melt adhesive film onto the placement surface 100a through the suction holes 100b to prevent wrinkles or gaps from being generated in the middle of the hot melt adhesive film.

[0103] Then the second motor 116 moves to drive the detection component 120 to fit the surface of the hot melt adhesive film, and the first motor 112 rotates to drive the detection component 120 to move, so as to drive the detection component 120 to detect the flatness of the TPU hot melt adhesive film to be detected placed on the placement surface 100a, and the contact state between the detection head 122 and the hot melt adhesive film will remain stable, thereby obtaining accurate detection results. The device can help to detect the flatness of the hot melt adhesive film in real time during the production process, ensure the firmness and durability of the adhesion, and improve the quality of the product.

[0104] The elastic member 143 is a spring; the air suction member 130 is an air pump.

[0110] In this embodiment, the TPU hot melt adhesive film to be tested is placed on the placement surface 100 a of the testing table 100 .

[0111] The moving component 110 is located on the testing platform 100 and can move in a direction parallel to the placement surface 100a. The moving component 110 moves in the direction of the placement surface 100a, driving the testing component 120 to test the TPU hot melt adhesive film placed on the placement surface 100a.

[0112] The flatness of the hot melt adhesive film is determined by measuring the state of the contact point. The movement of the moving component 110 enables the detection component 120 to detect the entire surface of the hot melt adhesive film to obtain flatness information.

[0113] The TPU hot melt adhesive film detection device can detect the flatness of the hot melt adhesive film to be detected.
