Technical Field
[0001] The present invention relates to the technical field of copper foil detection, and in particular to a copper foil testing machine and a testing method. Background Art
[0002] At present, copper foil needs to be subjected to a tensile test after processing. During the test, a long strip of copper foil is cut out and clamped on a testing machine at both ends in the length direction. The testing machine stretches the copper foil outward along its length direction and judges its ductility based on its elongation. Since the internal contraction force of the copper foil gradually increases during the stretching process, the clamping points at both ends of the copper foil are prone to slipping, which is a disadvantage. Summary of the invention
[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a copper foil testing machine and a testing method, in which both ends of the copper foil are clamped reliably and are not easy to slip off.
[0004] The invention discloses a copper foil testing machine, comprising a guide block, a spring, and two brackets. The two brackets are arranged opposite to each other up and down, and the brackets can move up and down. The brackets are installed with a driving member 2, and the output end of the driving member 2 is connected with a pressing plate, and the pressing plate can move left and right. The bracket comprises a platform, and the platform is slidably connected with a slider 2, and the slider 2 can move left and right. The slider 2 and the pressing plate are arranged opposite to each other left and right. A detection sheet can be placed between the slider 2 and the pressing plate, and the pressing plate is close to the slider 2 so that the slider 2 and the pressing plate press the detection sheet tightly. The platform is also slidably connected with a slider 1, and the slider 1 can move left and right. The two brackets move in a direction away from each other, and the inclined surface 1 gradually inclines toward the side close to the slider one. When the two brackets move in the direction away from each other, the inclined surface 1 pushes the slider one to make the slider one close to the slider two, and the spring one is compressed, thereby increasing the pressing force of the slider two and the pressure plate on the detection piece.
[0005] Furthermore, a plug plate is installed on the side of slider one close to slider two, and the plug plate includes a plug rod, which is inserted into slider two, and a push rod assembly is installed on slider two, and the push rod assembly includes a guide sleeve, which is inserted into slider two and fixed, and a push rod body is installed on the guide sleeve, and the push rod body is inserted into the guide sleeve, and the plug rod abuts against the push rod body, and the push rod body includes end two located on the side away from the plug rod, and the end two can abut against the detection piece, and the push rod body can move toward the side close to the detection piece under the push of the plug rod to press the end two into the detection piece.
[0006] Furthermore, the push rod body includes a slide located on the side away from the pressure plate, the guide sleeve is provided with hole two, the slide is inserted into hole two and can slide left and right along the hole wall of hole two, the guide sleeve is also provided with a step surface, the step surface is located between the slide and the pressure plate, and the outer wall of the push rod body is sleeved with spring two, the left end of the spring two abuts the step surface, and the right end of the spring two abuts the slide.
[0007] Furthermore, the second end is pressed into one side of the detection sheet to form a pointed end.
[0008] Furthermore, the guide sleeve is provided with a hole 1, the outer wall of the push rod body is provided with a spiral groove, and the hole wall of the hole 1 is provided with a protrusion corresponding to the spiral groove, so that the push rod body rotates when it moves left and right along the hole 1.
[0009] Furthermore, the insertion rod is provided with an end portion 1, which is hemispherical, and the spherical outer wall of the end portion 1 abuts against the center of the slide table.
[0010] Furthermore, it also includes a frame, and extension platforms are provided on the upper and lower sides of the frame. A driving component 1 is installed on the extension platform, and the output end of the driving component 1 is connected to the bracket.
[0011] The platform body is provided with a first slide rail and a second slide rail. The first slide rail is slidably connected to the first slider, and the second slide rail is slidably connected to the second slider.
[0012] The present invention also discloses a test method of a copper foil test machine, using the copper foil test machine, comprising the following test steps:
[0013] ① The two brackets are in the position closest to each other, and the upper and lower ends of the detection piece are pressed tightly by the pressing plate and the second slider;
[0014] ② Move the two brackets upward and downward away from each other, the detection sheet is stretched up and down, and the slider 1 gradually moves toward the slider 2 while following the movement of the bracket, so that the pressing force of the slider 2 and the pressure plate on the detection sheet increases;
[0015] When the slider 1 moves toward the side close to the slider 2, the insertion rod pushes the main body of the push rod to move to the left, so that the end 2 is pressed into the detection piece;
[0016] ③The two brackets move away from each other, the pressure plate retracts, and the test piece that has completed the test is taken out.
[0017] Furthermore, the main body of the push rod is a screw rod, and when the main body of the push rod moves, it rotates along its own axis, so that the second end portion is pressed into the detection piece in a spiral manner.
[0018] Beneficial effects of the present invention:
[0019] 1. When the two brackets move away from each other, the inclined surface 1 pushes the slider 1 to make the slider 1 close to the slider 2, and the spring 1 is compressed, so that the pressing force of the slider 2 and the pressure plate on the detection piece increases to prevent the pressing parts at both ends of the detection piece from slipping as the detection piece is stretched up and down.
[0020] 2. When the main body of the push rod moves left and right along the hole 1, it rotates along its own axis, so that the end 2 is pressed into the detection piece in a spiral manner, which makes it easier for the left end of the end 2 to press into the detection piece. When the end 2 is pressed into the detection piece, since the detection piece is made of copper foil and is relatively soft, a pit is formed on the surface of the detection piece due to the pressing of the end 2, thereby further preventing the end of the detection piece from slipping when pulling.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments in 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.
[0028] like Figure 1 -like Figure 2 As shown, a copper foil testing machine is used to test the tensile properties of a test piece 5 (i.e., a copper foil piece in the shape of a long thin strip). The tensile properties of the test piece 5 are determined by clamping the upper and lower ends of the test piece 5 and pulling them up and down, and calculating the tensile rate after the test. The test piece 5 remains intact during the test.
[0029] The copper foil testing machine includes a frame 1, and an extension platform 11 is provided at both ends of the frame 1, and the two extension platforms 11 are arranged opposite to each other, and a tensile test area is provided between the upper and lower extension platforms 11. The extension platform 11 is equipped with a driving member 111, and the driving member 111 is a cylinder, and the driving member 111 is fixedly connected with a bracket 3, and the two brackets 3 are arranged opposite to each other. Under the drive of the driving member 111, the brackets 3 can move up and down to make the two brackets 3 approach or move away from each other.
[0030] like Figure 3 , Figure 4 As shown, the bracket 3 is installed with a driving member 2 4 , which is a cylinder. The right output end of the driving member 2 4 is connected with a pressing plate 41 , and the pressing plate 41 can move left and right under the drive of the driving member 2 4 .
[0031] Combination Figure 2 The bracket 3 includes a platform 31, the platform 31 is equipped with a slide rail 1 311 and a slide rail 2 312, the slide rail 1 311 is equipped with a slider 1 6, and the slide rail 2 312 is equipped with a slider 2 9. Figure 3 The orientation shown is the main orientation, and both slider 1 6 and slider 2 9 can slide left and right, wherein slider 1 6 is located on the right side of slider 2 9, and pressure plate 41 is located on the left side of slider 2 9, slider 2 9 and pressure plate 41 are arranged opposite to each other left and right, and detection sheet 5 can be placed between slider 2 9 and pressure plate 41, and pressure plate 41 is close to slider 2 9 so that slider 2 9 and pressure plate 41 press detection sheet 5, and after both upper and lower ends of detection sheet 5 are pressed by slider 2 9 and pressure plate 41, they are driven up and down by driving member 111 to perform tensile test.
[0032] like Figure 3 , Figure 4 As shown, a countersunk hole 62 is provided on the left side of the slider 1 6 , and a spring 1 621 is placed in the countersunk hole 62 . The right end of the spring 1 621 abuts against the inner wall of the countersunk hole 62 , and the left end of the spring 1 621 abuts against the slider 2 9 .
[0033] like Figure 3 , Figure 4 As shown, the extension platform 11 is equipped with a guide block 2, which is located on the right side of the slider 1 6. The guide block 2 is provided with an inclined surface 1 21, and the slider 1 6 is provided with an inclined surface 2 61. The inclined surface 1 21 abuts against the inclined surface 2 61, and along the direction in which the two brackets 3 move away from each other, the inclined surface 1 21 gradually tilts toward the side close to the slider 1 6. When the two brackets 3 move in the direction in which they move away from each other, the inclined surface 1 21 pushes the slider 1 6 to make the slider 1 6 close to the slider 2 9, and the spring 1 621 is compressed, thereby increasing the pressing force of the slider 2 9 and the pressure plate 41 on the detection sheet 5, so as to prevent the pressing parts at both ends of the detection sheet 5 from slipping off as the upward and downward stretching amplitude of the detection sheet 5 increases.
[0034] like Figure 2 As shown, a plug plate 7 is installed on the side of the slider 1 6 close to the slider 2 9, and the plug plate 7 includes a plurality of plug rods 71, combined with Figure 4 , Figure 5 , the insertion rod 71 is inserted into the right end of the slider 2 9. The slider 2 9 is equipped with a push rod assembly 8, and the push rod assembly 8 includes a guide sleeve 81, which is a cylindrical structure. The guide sleeve 81 is inserted into the slider 2 9 and fixed. The guide sleeve 81 is equipped with a push rod body 82, and the push rod body 82 is inserted into the guide sleeve 81. The left end of the insertion rod 71 abuts against the push rod body 82. Specifically, the push rod body 82 includes a slide 822 located on the right side. The left end of the insertion rod 71 is provided with an end 711, and the end 711 is hemispherical. The spherical outer wall of the end 711 abuts against the center of the left end surface of the slide 822.
[0035] The push rod body 82 includes an end portion 821 located on the side away from the insertion rod 71. The left end of the end portion 821 is a pointed tip. The end portion 821 can abut the detection piece 5. The push rod body 82 can move toward the side close to the detection piece 5 under the push of the insertion rod 71, so that the left end of the end portion 821 is pressed into the detection piece 5, thereby increasing the clamping force on the end of the detection piece 5.
[0036] The guide sleeve 81 is provided with a hole 1 811 and a hole 2 812 located on the right side of the hole 1 811. The hole 2 812 has a larger diameter than the hole 1 811. The slide 822 is inserted into the hole 2 812 and can slide left and right along the hole wall of the hole 2 812. The guide sleeve 81 is also provided with a step surface 813. The step surface 813 is located between the slide 822 and the pressure plate 41. The outer wall of the push rod body 82 is sleeved with a spring 2 83. The left end of the spring 2 83 abuts against the step surface 813, and the right end of the spring 2 83 abuts against the slide 822. When the insertion rod 71 is retracted to the right, the push rod body 82 is retracted to the right under the action of the spring 2 83.
[0037] The main body 82 of the push rod is in the shape of a screw rod. The outer wall of the main body 82 of the push rod is provided with a spiral groove. The wall of the hole 811 is provided with a protrusion corresponding to the spiral groove ( Figure 5 In the figure, the protrusion is located near the second end 821), the protrusion is spiral and the number of spiral turns is one-fifth of a turn, and the protrusion is equivalent to a small section of the guide track, so that when the push rod body 82 moves left and right along the hole 1 811, it rotates along its own axis, so that when the second end 821 is pressed into the detection piece 5, it is pressed into a spiral manner, thereby facilitating the left end of the second end 821 to be pressed into the detection piece 5 more easily, and when the second end 821 is pressed into the detection piece 5, since the detection piece 5 is made of copper foil and is relatively soft, a pit is formed on the surface of the detection piece 5 due to the pressing of the second end 821, thereby further preventing the end of the detection piece 5 from slipping when pulling.
[0038] A test method of a copper foil testing machine, comprising the above copper foil testing machine, the specific test method is:
[0039] ① Such as Figure 4 As shown, the two brackets 3 are in the closest position to each other under the drive of the driving member 111, and the upper and lower ends of the detection sheet 5 are pressed tightly by the pressing plate 41 and the sliding block 2 9.
[0040] ② The two brackets 3 are driven away from each other by the driving member 111, and the detection sheet 5 is stretched up and down. When the slider 6 follows the movement of the bracket 3, due to the action of the inclined surface 21, the slider 6 gradually moves toward the side of the slider 2 9, so that the pressing force of the slider 2 9 and the pressure plate 41 on the detection sheet 5 is increased, preventing the two ends of the detection sheet 5 from slipping during the stretching process.
[0041] like Figure 5 As shown, when the slider 1 6 moves toward the side close to the slider 2 9, the insert rod 71 pushes the push rod body 82 to move to the left, so that the end 2 821 is pressed into the detection piece 5. At the same time, since the push rod body 82 is a screw, it rotates when moving to the left, making it easier for the end 2 821 to be pressed into the detection piece 5, thereby better preventing the detection piece 5 from falling off.
[0042] ③ The two brackets 3 are driven away from each other by the driving member 111, and the pressing plate 41 is driven to retract to the left by the driving member 2 4, and the test piece 5 after the test is taken out.
[0043] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
