Description

Technical Field

[0001] This application relates to the technical field of testing equipment, and particularly to a crosshatch test fixture. Background Art

[0002] For common metal products (such as mobile phone casings), decorative or protective film layers are usually formed on the outer surface of the metal substrate. For example, an anodic oxidation film formed by anodic oxidation treatment, or a metal or oxide film layer formed by physical vapor deposition, etc. During the manufacturing process, in order to detect the bonding strength between the film layer of the finished product and the metal substrate, the crosshatch test method is usually adopted. In the crosshatch test, the surface of the product needs to be treated first, that is, a single tool is used to draw grids on the surface of the product, so as to divide the surface film layer into multiple independent grids; after the surface treatment is completed, tape is used to stick each grid, so as to detect the bonding strength between the film layer and the metal substrate. At present, for the surface treatment of the crosshatch test, a limiting structure is usually set on the surface of the product, and the blade is manually held against the surface by hand to scratch out the lines. Since the surface hardness of metal products is high, the scratching process is time-consuming and laborious, the operation efficiency is low, and the blade is also easily damaged, resulting in high production costs.

[0097] The following specific embodiments will further illustrate the present application in conjunction with the above drawings. Specific embodiments

[0098] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments.

[0099] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0100] To further elaborate on the technical means and effects adopted by this application to achieve the predetermined purpose, the following provides a detailed description of this application in combination with the accompanying drawings and preferred embodiments.

[0101] Please refer to Figure 1 and Figure 2 , the crosshatch test fixture 100 of the embodiment of this application is used for surface treatment in the crosshatch test of products. The crosshatch test fixture 100 includes a scribing mechanism 10, a stroke limiting mechanism 30, and a positioning mechanism 50. Among them, the positioning mechanism 50 is used to carry and position the products that need surface treatment. The stroke limiting mechanism 30 is disposed on the positioning mechanism 50 and is located between the positioning mechanism 50 and the scribing mechanism 10. The stroke limiting mechanism 30 carries the scribing mechanism 10 to limit the movement of the scribing mechanism 10 relative to the positioning mechanism 50 in the first direction X and the second direction Y. The scribing mechanism 10 is disposed on the side of the stroke limiting mechanism 30 away from the positioning mechanism 30. The scribing mechanism 10 is used to perform surface treatment on the surface of the product to form the scratches for the crosshatch test.

[0102] Please refer to Figure 3 , the scribing mechanism 10 includes a blade module 11 and a transmission module 13. The transmission module 13 is in transmission connection with the blade module 11. Among them, the blade module 11 includes a housing component 113 and a plurality of blades 111 stacked in parallel and received at one end of the housing component 113. The cutting edge of each blade 111 is arranged facing the positioning mechanism 50. The transmission module 13 is used to drive the blade 111 to move in a direction close to or away from the positioning mechanism 50.

[0103] Please refer to Figure 4 , the blade module 11 further includes a plurality of spacers 112, a limit slider 115, and a fastener 117. Among them, each spacer 112 is disposed between two adjacent blades 111, so that the plurality of blades 111 are spaced from each other. The housing component 113 is provided with a receiving groove 1136. The plurality of blades 111 are stacked in the receiving groove 1136. The limit slider 115 is at least partially disposed in the receiving groove 1136 and is located on one side of the plurality of blades 111 to press the plurality of blades 111. The fastener 117 is disposed at the end of the limit slider 115 away from the receiving groove 1136 to abut against the limit slider 115, so that the limit slider 115 is pressed in the receiving groove 1136.

[0104] In this embodiment, the number of blades 111 of the blade module 11 is three. In other embodiments, the number of blades 111 can also be correspondingly set according to the number of scratches to be engraved on the product surface, and the present application does not limit this.

[0105] Among them, the accommodating component 113 includes a first accommodating member 1131 and a second accommodating member 1133. An accommodating groove 1136 is formed on one side surface of the first accommodating member 1131. The second accommodating member 1133 is disposed on one side of the first accommodating member 1131 and covers the accommodating groove 1136. A plurality of blades 111 are placed in the accommodating groove 1136 and thus covered by the second accommodating member 1133.

[0106] Please refer to Figure 5 , the first accommodating member 1131 includes a first groove wall 1132 arranged parallel to the blade 111 and a second groove wall 1134 arranged obliquely with respect to the blade 111. The limiting slider 115 includes a first side wall 1151 arranged parallel to the first groove wall 1132 and a second side wall 1153 arranged parallel to the second groove wall 1134. The first side wall 1151 abuts against one blade 111 to press a plurality of first blades 111 against the first groove wall 1132. The second side wall 1153 abuts against the second groove wall 1134 and is movable along the extending direction of the second groove wall 1134. When the limiting slider 115 moves towards the direction close to the accommodating groove 1136, the limiting slider 115 abuts against a plurality of blades 111, thereby achieving the effect of tightly limiting the plurality of blades 111. When the limiting slider 115 moves towards the direction away from the accommodating groove 1136, the force exerted by the limiting slider 115 on the blades 111 gradually decreases and finally no longer contacts the blades 111. At this time, the blades 111 can be taken out from the accommodating groove 1136 or placed into the accommodating groove 1136, thereby completing the replacement of the blades 111.

[0107] The limiting slider 115 further includes a reset portion 1155. The reset portion 1155 is located at one end of the limiting slider 115 away from the accommodating groove 1136 and penetrates through the second accommodating member 1133. The reset portion 1155 is used to drive the limiting slider 115 away from the accommodating groove 1136, thereby reducing the force exerted on the blades 111, and further facilitating taking out the blades 111 from the accommodating groove 1136 for replacement.

[0108] The fastener 117 is specifically a bolt. The fastener 117 is disposed on the side of the second accommodating member 1133 away from the first accommodating member 1131. The stud 1171 of the fastener 117 passes through the second accommodating member 1133 to abut against the limiting slider 115. By adjusting the fastener 117, the limiting slider 115 can be pressed towards the accommodating groove 1136, thereby achieving the fastening of the blades 111.

[0109] In this embodiment, the distance between two adjacent blades 111 is 1 ± 0.05 mm. Specifically, the distance between the blades 111 is the distance between the scratches made on the product surface. The distance between two adjacent blades 111 can be adjusted by the thickness of the blades 111 themselves and the thickness of the spacers 112. In other embodiments, the distance between the blades 111 can also be set according to specific usage requirements, and the present application does not limit this.

[0110] Please refer to Figure 6 , the blade module 11 further includes a positioning member 119 for positioning the blades 111. Specifically, after replacing the blades 111, it is necessary to align the positions of multiple blades 111 so that the depths of the scratches made by the multiple blades 111 are the same. The positioning member 119 is an independently provided part. When it is necessary to align the blades 111, the positioning member 119 can be placed at the end of the blades 111, and after the alignment is completed, the positioning member 119 needs to be removed.

[0111] Please refer to Figure 7 , the transmission module 13 includes a base 131, a support portion 132, a transmission component 133, and a grip component 135. Among them, the base 131 bears the support portion 132, the transmission component 133, and the grip component 135. The blade module 11 is rotatably arranged on the support portion 132, and one end of the transmission component 133 is rotatably connected to the end of the blade module 11 away from the multiple blades 111. The grip component 135 is connected to the other end of the transmission component 133. The grip component 135 drives the blade module 11 to rotate by pulling the transmission component 133, so that the blades 111 move in a direction approaching or away from the positioning mechanism 50.

[0112] Specifically, the support portion 132 is a support shaft structure fixed on the base 131, and the support portion 132 is rotatably connected to the blade module 11, so that the blade module 11 can rotate relative to the support portion 132. The transmission component 133 includes a first transmission rod 1331 and a second transmission rod 1333, and the first transmission rod 1331 is rotatably connected to the second transmission rod 1333. The first transmission rod 1331 is arranged on the base 131 and can move on the base 131. The second transmission rod 1333 is connected to one end of the first transmission rod 1331 and the end of the blade module 11 without the blades 111, and is rotatably connected to the blade module 11. When the first transmission rod 1331 moves, it will drive one end of the second transmission rod 1333 to move, thereby driving the end of the blade module 11 to move, and further causing the blade module 11 to rotate relative to the support portion 132, so that the blades 111 can move in a direction approaching or away from the positioning mechanism 50, and further contact the surface P1 of the product P.

[0113] The holding assembly 135 includes a first grip 1351 and a second grip 1353. The first grip 1351 is connected to the first transmission rod 1331 and is movable on the base 131. The second grip 1353 is fixed on the base 131. The first grip 1351 and the second grip 1353 are paired, and through the holding operation, the first grip 1351 can be moved towards the second grip 1353, thereby driving the first transmission rod 1331 to move towards the second grip 1353 and driving the second transmission rod 1333 to move, so as to drive the blade module 11 to rotate.

[0114] Please refer to Figure 8 , when the holding assembly 135 is held, the first transmission rod 1331 and the second transmission rod 1333 are in an approximately perpendicular state. At this time, the second transmission rod 1333 jacks up the other end of the blade module 11 where the blade 111 is not provided, so that the blade 111 is pressed onto the surface P1 of the product P through a lever structure. Therefore, by setting the transmission assembly 133 and the holding assembly 15, the force directly pressing the blade 111 against the product P can be converted into the force of holding the first grip 1351 and the second grip 1353, which is more convenient for operation. In other embodiments, the structure of the transmission assembly 133 can also be adjusted according to actual needs. For example, it can be set that when the holding assembly 135 is held tightly, the blade 111 is away from the surface P1 of the product P, and when the holding assembly 135 is released, the blade 111 moves towards the product P. The present application does not limit this.

[0115] In this embodiment, when the holding assembly 135 is not held, the distance a between the blade 111 and the surface P1 of the product P is less than 1.7 mm. When the holding assembly 135 is held, the distance b that the blade 111 is embedded into the surface P1 of the product P is less than 0.5 mm. By setting the specific dimensions of the transmission assembly 133 and the holding assembly 135, the moving range of the blade 111 can be adjusted accordingly, so as to facilitate the surface treatment of the surface P1 of the product P.

[0116] Please refer to Figure 9 , the stroke limiting mechanism 30 includes a limiting plate 31, a first limiting frame 33 and a second limiting frame 35. The limiting plate 31 is used to carry the scribing mechanism 10. The first limiting frame 33 is sleeved on the limiting plate 31 and is used to limit the movement of the limiting plate 31 in the first direction X. The second limiting frame 35 is sleeved outside the first limiting frame 33 and is used to limit the position of the first limiting frame 33 in the second direction Y. The second limiting frame 35 is fixed on the positioning mechanism 50.

[0117] The limiting plate 31 is provided with a first limiting post 311 and a second limiting post 313. The first limiting post 311 and the second limiting post 313 are used to connect with the scribing mechanism 10 and fix the position of the scribing mechanism 10.

[0118] The first limit frame 33 includes a limit guide rail 331 and a limit frame 333. The limit guide rail 331 extends along the first direction X. The limit plate 31 is movably arranged on the limit guide rail 331, so that it can move along the limit guide rail 331, thereby driving the scribing mechanism 10 to move in the first direction X.

[0119] Please refer to Figure 9 and Figure 10 , the limit frames 333 are located at opposite ends of the first limit frame 33 in the first direction X and are connected to the second limit frame 35. A limit protrusion 335 is provided on the limit frame 333. A plurality of limit slot holes 352 arranged along the second direction Y are formed on the second limit frame 35. The limit protrusion 335 can be received in any one of the limit slot holes 352, so that the first limit frame 33 can be set at different positions in the second direction Y, and further the scribing mechanism 10 can be set at different positions in the second direction Y.

[0120] In this embodiment, the distance between two adjacent limit slot holes 352 is 3mm ± 0.05mm. Specifically, since the number of blades 111 is 3 and the distance between two adjacent blades 111 is 1 ± 0.05mm, therefore, by setting the distance between two adjacent limit slot holes 352 to be 3mm ± 0.05mm, when the first limit frame 33 is transferred from one limit slot hole 352 to another adjacent limit slot hole 352, the distance between the scribed marks on the surface P1 of the product P by the scribing mechanism 10 and the previous scribed marks is exactly 1 ± 0.5mm. Thus, the equal spacing is maintained between the multiple parallel scribed marks.

[0121] Please refer to Figure 11 , by setting the stroke limit mechanism 30, the blade 111 can be moved along the first direction X, so as to scribe a scratch B on the surface P1. By moving the relative positions of the first limit frame 33 and the second limit frame 35 in the second direction Y, multiple parallel scratches B can be scribed on the surface P1. By rotating the product P by 90°, multiple scratches A perpendicular to the scratches B can be scribed, thereby forming the scratches for the crosshatch test on the surface P1 of the product P.

[0122] Please refer to Figure 12 and Figure 13, a first limiting hole 1312 is further formed in the base 131. The first limiting post 311 passes through the first limiting hole 1312. The stroke limiting mechanism 30 further includes a positioning block 37 which is arranged in the first limiting hole 1312 to abut against the first limiting post 311. Specifically, the first limiting post 311 is used to cooperate with the positioning block 37 to fix the base 131. A limiting portion is arranged at one end of the first limiting post 311 away from the limiting plate 31, and the limiting portion can engage with the base 131 on the side of the base 131 away from the limiting plate 31, so as to fix the base 131. When the positioning block 37 is placed in the first limiting hole 1312, the position of the base 131 in the first direction X is fixed, so as to realize the fixation relative to the limiting plate 31. After the positioning block 37 is taken out from the first limiting hole 1312, the base 131 is movable in the first direction X, so that the limiting portion can be aligned with the first limiting hole 1312 only by moving in the first direction X, and the base 131 can be taken out from the limiting plate 31.

[0123] Please refer to Figure 14 , a second limiting hole 1314 is further formed in the base 131. The second limiting post 313 is partially located in the second limiting hole 1314 along the first direction X, so as to engage with the base 131. Specifically, when the base 131 is placed on the limiting plate 31, the first limiting post 311 passes through the first limiting hole 1312, and the second limiting post 313 does not contact the second limiting hole 1314 but is aligned with the second limiting hole 1314. Then the base 131 moves along the first direction X, so that the limiting portion of the first limiting post 311 engages with the base 131, and the second limiting post 313 is partially inserted into the second limiting hole 1314, so as to engage with the base 131.

[0124] The grid test fixture 100 provided by the embodiment of the present application can realize the quick disassembly of the base 131 by arranging the first limiting post 311 and the second limiting post 313 and cooperating with the positioning block 37, so as to facilitate the quick replacement of the scribing mechanism 10 and is beneficial to improving the production efficiency.

[0125] Please refer to Figure 15 , the positioning mechanism 50 includes a base 51, a positioning component 53 and a supporting component 55. The base 51 bears the positioning component 53 and the supporting component 55. The positioning component 53 includes a positioning fixture 531 and a positioning pin 533. The supporting component 55 bears the stroke limiting mechanism 30.

[0126] Among them, the positioning fixture 531 includes a first positioning member 5311 and a second positioning member 5313. The first positioning member 5311 is arranged on the base 51, and the second positioning member 5313 is arranged on the side of the first positioning member 5311 away from the base 51 for fixing the product P.

[0127] Please refer to Figure 16, in this embodiment, the product P is a cuboid frame, and a coating is plated on the surface P1 of the product P. Therefore, a cross-hatch test needs to be performed to detect the adhesion of the film layer. The product P is fixed on the second positioning member 5313 by a positioning screw 5315. In other embodiments, the product P may also have other structures, and the product P may also be fixed on the second positioning member 5313 by a snap or other means, which is not limited in this application.

[0128] Please refer to Figure 17 , a first slide rail 511 and a first positioning hole 513 are formed on the base 51. The first slide rail 511 is parallel to the second direction Y. The first positioning member 5311 is placed on the base 51 along the first slide rail 511. The positioning pin 533 passes through the first positioning member 5311 and at least partially passes through the first positioning hole 513, so as to position the first positioning member 5311 on the base 51 and make the product P arranged in the orientation extending along the second direction Y.

[0129] Please refer to Figure 18 and Figure 19 , a second slide rail 515 and a second positioning hole 517 are further formed on the base 51. The second slide rail 515 is parallel to the first direction X and is used to guide the first positioning member 5311 to be placed along the second slide rail 515, so that the product P is arranged in the orientation extending along the first direction X. The positioning pin 533 passes through the first positioning member 5311 and at least partially passes through the second positioning hole 517, so as to fix the first positioning member 5311.

[0130] The positioning mechanism 50 provided by the embodiment of the present application can position the product P in two mutually perpendicular directions, so that the direction of the scratch formed by the scribing mechanism 10 on the surface P1 can be changed by changing the orientation of the product P, without adjusting the direction of the scribing mechanism 10, which is beneficial to improving production efficiency.

[0131] The working principle of the positioning mechanism 50 provided by the embodiment of the present application will be further described below.

[0132] First, the product P is fixed on the second positioning member 5313, and then the second positioning member 5313 is fixed on the first positioning member 5311. Then, the positioning jig 531 is placed along one of the first slide rail 511 or the second slide rail 515, and the positioning pin 533 passes through the first positioning member 5311 and passes through one of the first positioning hole 513 or the second positioning hole 517, so as to fix the positioning jig 531 on the base 51.

[0133] After that, the stroke limiting mechanism 30 is placed on the support assembly 55, and the relative positions of the first limiting frame 33 and the second limiting frame 35 in the second direction Y are adjusted. Then, the scribing mechanism 10 is fixed on the limiting plate 31. At this time, the positional relationship between the blade 111 and the product P is asFigure 7 as shown

[0134] After that, pull the first grip 1351 so that the first grip 1351 moves towards the second grip 1353, thereby driving the first transmission rod 1331 to move in the direction of the second grip 1353. When the first transmission rod 1331 moves towards the second grip 1353, the state where the second transmission rod 1333 is inclined relative to the base 131 is converted into a state perpendicular to the base 131. That is, the end of the second transmission rod 1333 away from the first transmission rod 1331 will move away from the base 131 as the first transmission rod 1331 moves towards the second grip 1353, and will jack up the end of the blade module 11 in the direction away from the base 131. Since the blade module 11 rotates relative to the support portion 132, the end of the blade module 11 provided with the blade 111 moves towards the direction close to the product P, thereby pressing onto the surface P1 of the product P. As Figure 8 shown

[0135] After that, while holding the first grip 1351 and the second grip 1353, drag the scribing mechanism 10 along the first direction X, so that the blade 111 moves along the first direction X, and then form a scratch on the surface P1 of the product P.

[0136] After that, by adjusting the relative positions of the first limit frame 33 and the second limit frame 35 in the second direction Y, and adjusting the orientation of the positioning fixture 531 on the base 51, then repeat the operation of holding the first grip 1351 and the second grip 1353 and dragging the scribing mechanism 10, and finally form a grid-like scratch on the surface P1 of the product P.

[0137] The positioning mechanism 50 provided by the embodiment of the present application, by setting the scribing mechanism 10, can save the force required for scribing on the surface of the product P, and can change the direction of the applied force, which is beneficial to reducing the operation difficulty and reducing the labor cost. By setting the stroke limiting mechanism 30, it is beneficial to limit the movement of the scribing mechanism 10, so as to facilitate scribing multiple parallel and equally spaced scratches, which is beneficial to reducing the operation difficulty. By setting the positioning mechanism 50, the orientation of the product P can be adjusted through the positioning component 53, so as to facilitate scribing crossed scratches on the surface P1, which is beneficial to improving the operation efficiency.

[0138] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as within the scope of the substantial spirit of the present application, appropriate changes and variations made to the above embodiments fall within the scope of protection required by the present application.
