Description

Technical Field

[0001] The invention relates to the technical field of bead-planted reflective film detection, and in particular to a reflective film defect quality inspection device. Background Art

[0002] Reflective film is a kind of retro-reflective material that can be directly used after being made into a thin film. It is made through glass bead technology, microprism technology, synthetic resin technology, thin film technology, coating technology and micro-replication technology. It is widely used as a sign in various aspects of life, such as road signs, truck body identification, clothing with warning functions, etc.

[0003] Among them, glass microbeads are planted on the polymer original film through a bead planting process to form a bead-planted reflective film. However, during the bead planting process, the glass microbeads are prone to tumbling, colliding, and rubbing, causing the glass microbeads to wear and break. The glass microbeads after friction are prone to generate static electricity, resulting in beads, overlapping beads, and floating beads in the bead planting process, which reduces the anti-static performance and wear resistance of the reflective film, resulting in accelerated wear and dust adhesion when the reflective film is used outdoors later, reducing the service life and reflective ability of the reflective film.

[0004] Therefore, a reflective film defect inspection device is now proposed. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

By setting up a quality inspection drive mechanism and a quality inspection mechanism to cooperate with each other, the anti-static performance and wear resistance strength can be tested at the same time, and the static voltage on the surface of the reflective film before and after friction electrification and the wear amount of the friction disk are used as the test standards for the anti-static performance and wear resistance of the reflective film, so as to quickly detect whether the reflective film has a reduced performance due to defects in implanting beads after the reflective film is implanted with glass beads, thereby achieving the effect of improving the detection of reflective film characteristics.

[0021] 2. By equipping the material uniformity detection component with a force-sensitive detection touch block, the reflective film after tearing sampling can be subjected to a tearing test by means of friction tearing. Based on the principle of air negative pressure, the increase in air pressure in the sealed tube is used as the condition for the descent of the sealing cover in the intermittent negative pressure tube, so as to conveniently determine whether the reflective film is torn uniformly under the same friction force. In this way, the material uniformity of the reflective film can be used to detect whether the material is uneven due to implantation defects during the implantation of glass microbeads.

[0022] 3. By using an electrostatic release bracket equipped with a telescopic elastic component, the weight of the friction disc can be applied to the supporting column during the friction electrification process, and the weight of the friction disc can be applied to the supporting sheet during the anti-static performance test. In this way, the weight of the friction disc can be selectively tested by the different supporting parts of the friction disc, thereby achieving the effect of selectively testing the wear resistance of the reflective film.

[0023] 4. Through the cooperation between the tear strength sampling table and the sampling notch, the reflective film can be torn and sampled, and it can be raised to the tear strength detection height, that is, the material uniformity detection height, and rubbed against the bottom of the friction disk, so as to achieve the effect of convenient sampling.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Reference Figure 1-Figure 8 A reflective film defect quality inspection device includes a quality inspection platform 1 for detecting the weight of a beaded reflective film. A reflective film ring cutting mechanism is arranged on the top of the quality inspection platform 1. The reflective film ring cutting mechanism is used to perform ring-shaped lamination and shearing on the beaded reflective film involved in the quality inspection. A quality inspection unit is arranged on the quality inspection platform 1. The quality inspection unit consists of a quality inspection driving mechanism and a quality inspection mechanism. The quality inspection driving mechanism is used to drive the quality inspection mechanism during the quality inspection of the beaded reflective film. The quality inspection mechanism is used to detect the antistatic performance, wear resistance and material uniformity of the beaded reflective film.

[0036] Through the above technical scheme, the antistatic performance of the bead-embedded reflective film in the present invention is detected by taking the static voltage of the reflective film after friction as the detection standard, its wear resistance is detected by taking the wear amount of the friction disk 6 before and after friction electrification as the detection standard, and its material uniformity is detected by taking the tear strength of the reflective film after sampling as the detection standard.

[0037] like Figure 1 and Figure 3 As shown, the reflective film annular cutting mechanism includes a cutting drive motor 2 arranged inside the quality inspection table 1, the cutting drive motor 2 is connected to a cutting annular cutter 22 through a driving gear 21, and a bonding negative pressure cylinder 3 is arranged below the cutting drive motor 2, and the bonding negative pressure cylinder 3 adsorbs the bottom of the bead-planted reflective film through a bonding negative pressure tube 31;

[0038] Through the above technical solution, such as Figure 4-Figure 6 As shown, the inner wall of the quality inspection table 1 is rotatably connected to a stabilizing gear 11 which is transmission-connected to the cutting ring tool 22, and the top of the cutting ring tool 22 is set to be serrated, so that when the cutting drive motor 2 is started to drive the cutting ring tool 22 to rise, the serrated tip contacts the reflective film first, and when it continues to rise, the edge area of ​​the reflective film is cut in a ring so that it conforms to the friction range of the bottom of the quality inspection drive disk 41, and the fitting negative pressure tube 31 is composed of an edge negative pressure tube 311 and a center negative pressure tube 312, and the edge negative pressure tubes 311 are distributed on the inner and outer sides of the cutting ring tool 22.

[0039] like Figure 4 and Figure 6As shown, the quality inspection drive mechanism includes a servo motor 4 arranged on the top of the quality inspection platform 1 and a lifting negative pressure pipe network 5 connected to the top of the fitting negative pressure cylinder 3. The servo motor 4 is fixed with a quality inspection drive disk 41 through an output shaft, and the lifting negative pressure pipe network 5 is composed of a telescopic negative pressure pipe 51 and an intermittent negative pressure pipe 52.

[0040] Through the above technical scheme, the quality inspection drive disk 41 is driven to rotate by the servo motor 4 to provide rotational drive for the friction disk 6, and one end of the reflective film after tear strength sampling can be stabilized by the top of the telescopic negative pressure tube 51, and the intermittent negative pressure tube 52 stabilizes the other end of the reflective film after sampling, and the reflective film after sampling is continuously adsorbed by the bonding negative pressure cylinder 3 in the telescopic negative pressure tube 51, and the negative pressure is first provided by the bonding negative pressure cylinder 3 in the intermittent negative pressure tube 52, and then the negative pressure is increased again by extending the intermittent negative pressure tube 52, but the air pressure in the extended intermittent negative pressure tube 52 is greater than that in the telescopic negative pressure tube 51, that is, the suction force of the intermittent negative pressure tube 52 on the reflective film after tearing sampling is less than the suction force of the telescopic negative pressure tube 51 on the reflective film.

[0041] like Figure 2 and Figure 4 As shown, the quality inspection mechanism consists of an anti-static detection component, a wear resistance detection component and a material uniformity detection component. The anti-static detection component includes a friction disk 6 arranged at the bottom of the quality inspection drive disk 41. The inner wall of the friction disk 6 is slidably connected with an electrostatic release bracket 61. The top of the electrostatic release bracket 61 is provided with an electrostatic release metal ring 62, and the top of the electrostatic release metal ring 62 is touch-connected with an electrostatic voltage detector 63. The electrostatic voltage detector 63 consists of a multimeter and a touch conductive sheet 631.

[0042] Through the above technical solution, the electrostatic release bracket 61 is clamped with the friction disc 6 through the supporting column 611. When the friction disc 6 is lowered by the lifting drive bracket 74 driven by the lifting drive cylinder 75, the friction disc 6 is held by the supporting column 611. At this time, the weight of the friction disc 6 is supported by the supporting column 611, and a telescopic elastic component 64 is provided on the top of the electrostatic release bracket 61, so as to pull the friction disc 6 upward under normal conditions.

[0043] Based on the above, after the friction disk 6 rubs the reflective film for a period of time, the electrostatic release metal ring 62 is driven to drop synchronously by pressing down the conductive sheet 631, so that the supporting column 611 is in direct contact with the reflective film. At this time, the static voltage carried by the top of the reflective film is transmitted to the multimeter through the electrostatic release bracket 61, and the maximum static voltage of its initial release is measured.

[0044] like Figure 1 and Figure 2As shown, the wear resistance strength detection component includes a wear resistance detection sleeve 7 arranged inside the quality inspection drive disk 41, a wear resistance detection column 71 is arranged inside the wear resistance detection sleeve 7, a wear resistance detector is arranged on the top of the wear resistance detection column 71, and the wear resistance detector is composed of a spring tension detector 72 and a tension spring 73. The outer side of the quality inspection drive disk 41 is rotatably connected to a lifting drive bracket 74, and the lifting and lowering of the lifting drive bracket 74 is controlled by a lifting drive cylinder 75.

[0045] Through the above technical scheme, a supporting plate 711 is provided at the bottom of the wear-resistant detection column 71, and the top of the supporting plate 711 is in contact with the bottom of the friction disk 6, so that after the friction disk 6 frictionally charges the reflective film, the friction disk 6 is synchronously lowered by the descending of the supporting column 611, and after descending to the top of the supporting plate 711, the entire weight of the friction disk 6 is supported by the supporting plate 711, so that the tension measured by the spring tension detector 72 arranged on the top can be compared with the tension before friction, so as to obtain the wear amount of the friction disk 6 before and after the friction charging.

[0046] Based on the above, the supporting plate 711 and the wear-resistant detection column 71 and the supporting column 611 and the electrostatic release bracket 61 are installed by threaded connection, so that the friction disc 6 can be easily replaced after a period of quality inspection of the friction disc 6, and the outer surface of the supporting column 611 is set as a conical surface. During the friction electrification process of the friction disc 6, the supporting column 611 is located inside the friction disc 6 and does not directly contact the reflective film, thereby avoiding the direct release of static electricity on the surface of the reflective film before testing.

[0047] like Figure 3 , Figure 7 and Figure 8 As shown, the material uniformity detection component includes a negative pressure contact detector arranged at the bottom of the intermittent negative pressure tube 52, the negative pressure contact detector is composed of a force-sensitive detection touch block 8 and a threshold trigger light 81, and the bottom of the intermittent negative pressure tube 52 is fixed inside the quality inspection table 1, and the top of the intermittent negative pressure tube 52 is in contact with the bead-planted reflective film.

[0048] Through the above technical scheme, a tear strength sampling platform 9 is arranged on the top of the telescopic negative pressure tube 51 and the intermittent negative pressure tube 52, and a sealing tube 91 is fixed on the inner wall of the tear strength sampling platform 9 and is sealingly and slidably connected to the intermittent negative pressure tube 52. A sampling slot 12 is opened on the top of the quality inspection platform 1, and a lifting drive hydraulic cylinder 92 is arranged inside the quality inspection platform 1. The lifting drive hydraulic cylinder 92 drives the telescopic negative pressure tube 51 to be extended and retracted through a hydraulic connecting rod 921.

[0049] Based on the above, a connecting passage is opened between the intermittent negative pressure tube 52 and the telescopic negative pressure tube 51, and the connecting passage is closed after the telescopic negative pressure tube 51 rises to a certain height. At this time, the negative pressure inside the intermittent negative pressure tube 52 is maintained at the negative pressure when the connecting passage is closed, and a sealing cover that slides in a sealed manner with the sealing tube 91 is provided on the top of the intermittent negative pressure tube 52. Then, the sliding part on the top of the intermittent negative pressure tube 52 continues to move upward along with the sliding part on the top of the telescopic negative pressure tube 51, so that the sealing tube 91 is under negative pressure, and the reflective film on the top is adsorbed. When the friction disk 6 rubs and tears the reflective film after sampling, the sealing tube 91 is turned on, so that the sealing cover drops, presses down on the top of the force-sensitive detection touch block 8, and turns on the threshold trigger light 81, thereby reversely indicating that the reflective film is torn after sampling here.

[0050] Working principle:

[0051] When the present invention conducts defect quality inspection on the bead-planted reflective film made by the glass microbead process, it will sequentially go through the processes of bead-planted reflective film lamination and cutting, anti-static performance test after friction electrification, wear resistance test after friction and tear strength test after tear sampling, wherein the reflective film lamination and cutting process is specifically as follows: the lamination negative pressure cylinder 3 makes the internal negative pressure of the lamination negative pressure tube 31 negative, so that the bottom of the bead-planted reflective film is adsorbed on the top of the quality inspection table 1, and then the cutting drive motor 2 drives the cutting ring tool 22 to rise, and performs circular shearing on the edge of the reflective film after adsorption and lamination by the edge negative pressure tube 311, to ensure that the reflective film after shearing is compatible with the projection of the friction disk 6, to avoid excessive shearing area, resulting in insufficient friction on the surface of the reflective film, and affecting the anti-static performance and wear resistance test process.

[0052] Based on the above, the anti-static performance detection process of the beaded reflective film after friction electrification is specifically as follows: after the reflective film is pasted and sheared, the lifting drive cylinder 75 is started to drive the lifting drive bracket 74 to descend, and the servo motor 4 is started to drive the quality inspection drive disk 41 to rotate, thereby driving the friction disk 6 to rotate synchronously, and rubbing the upper surface of the reflective film after the ring cutting, and after its rotation reaches the specified time, the lifting drive cylinder 75 is started to drive the lifting drive bracket 74 to rise, and the electrostatic release bracket 61 is driven to descend by pressing down the conductive sheet 631 to fit with the surface of the reflective film, so that the static voltage of the reflective film during the electrostatic release process is measured by the multimeter, and the static voltage intensity of the reflective film detected by the electrostatic release bracket 61 when the electrostatic release bracket 61 first contacts the reflective film, and the anti-static performance of the reflective film is judged, and the anti-static performance detection process of the beaded reflective film after friction electrification is completed;

[0053] Based on the above, the wear resistance test process of the implanted reflective film after friction is specifically as follows: after the anti-static performance test process after the implanted reflective film is frictionally electrified is completed, the friction disc 6 is suspended on the top of the quality inspection table 1, and at the same time, when the electrostatic release bracket 61 descends, the overall weight of the friction disc 6 is completely borne by the supporting plate 711, so that the weight of the friction disc 6 at this time is detected by the spring tension detector 72 on the top of the supporting plate 711, and combined with the weight of the friction disc 6 before the anti-static performance test, the amount of friction electrification wear between the friction disc 6 and the reflective film per unit time can be obtained, and then the wear resistance of the reflective film before and after the friction electrification process can be reflected through the material impairment between the two.

[0054] Based on the above, the tear strength detection process of the bead-planted reflective film after tearing and sampling is specifically as follows: after the anti-static performance and wear resistance strength detection of the bead-planted reflective film is completed, the lifting and driving hydraulic cylinder 92 is started to drive the tear strength sampling platform 9 to descend first, so that the reflective film contacts the sampling notch 12, and shear sampling is performed on it, and then the lifting and driving hydraulic cylinder 92 drives the tear strength sampling platform 9 to rise, so that the reflective film fits the lower bottom surface of the friction disk 6 after the rise, and then the servo motor 4 is started to drive the friction disk 6 to continue to rotate, and the reflective film after tearing and sampling is tested. After it is torn, the adsorption of the intermittent negative pressure tube 52 is cancelled, so that the intermittent negative pressure tube 52 slides down to the top of the force-sensitive detection touch block 8, and the threshold trigger light 81 is turned on, so that according to the number and position of the threshold trigger light 81, it can be known whether the tear strength of the reflective film after tearing and sampling is consistent under the same friction force at the bottom of the friction disk 6, that is, whether the reflective film is torn at the same time and consistently, and this is used as a criterion for judging the uniformity of the bead-planted reflective film material.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
