Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrolytic copper foil detection devices, in particular to an electrolytic copper foil sampling detection device. Background Art
[0002] Electrolytic copper foil is a type of copper foil made through an electrolytic process and is commonly used in the electronics industry as a conductive substrate for circuit boards. Usually, before leaving the factory, it is necessary to conduct tests such as thickness and width, surface roughness, tensile strength, ductility, conductivity, chemical composition, flatness, and corrosion resistance. The tensile test of electrolytic copper foil uses a tensile tester to clamp the two ends of the electrolytic copper foil through a clamping device. One set of clamping devices is connected to a sensor. When a tensile force is applied, the force sensor detects the change in tension and converts it into an electrical signal. The electrical signal is processed and displayed on the display screen of the control panel. Based on the readings on the display screen, the user can judge the physical properties of the copper foil such as tensile strength and ductility.
[0003] In the existing tensile tester, the clamping device of the copper foil has different thickness, texture and surface treatment conditions of the copper foil. On the other hand, the clamping device wears out after long-term use, which may lead to loose clamping. Before the test is completed, the copper foil falls off the clamping device prematurely, seriously affecting the test results. Therefore, it is necessary to provide an electrolytic copper foil sampling and testing device to solve the above problems. Utility Model Content

[0010] Furthermore, after the first clamping plate and the second clamping plate are clamped, the clamping surfaces are on the same plane.
[0011] Furthermore, the tensile test force includes an equipment base, a column, a sensor and a support plate. The equipment base is placed on the work surface, the column is fixed at one end of the upper surface of the equipment base, and a linear track is installed inside the column. The sensor is fixed on the slider of the linear track, and the support plate is fixed at one end of the upper surface of the equipment base and is located below the sensor.

By turning the adjusting knob, the first clamping plate is driven to move and clamp the copper foil. At this time, the second clamping plate is restricted by the side of the U-shaped support frame. As the first clamping plate moves, it rotates around the connecting axis on the fixed plate until the copper foil is clamped.

[0027] See also Figure 1-3 As shown, this embodiment is a sampling and detection device for electrolytic copper foil, comprising:
[0028] The tensile tester includes a U-shaped support frame 14, an adjusting knob 15 and a first clamping plate 16. The adjusting knob 15 passes through and is screwed to the side of the U-shaped support frame 14, and one end of the adjusting knob 15 located inside the U-shaped support frame 14 is rotatably connected to the side of the first clamping plate 16. The lower end of the first clamping plate 16 is slidably connected to the U-shaped support frame 14 through a limiter.
[0029] The tensile test force includes an equipment base 10, a column 11, a sensor 12 and a support plate 13. The equipment base 10 is placed on the work surface, the column 11 is fixed at one end of the upper surface of the equipment base 10, and a linear track is installed inside the column 11.

[0032] The first reinforcement assembly includes a fixing plate 20, a connecting shaft 21, a torsion spring 22, a second clamping plate 23 and a square through hole 24. The fixing plates 20 are two in total, fixed to the two ends of the top of the first clamping plate 16 respectively, the connecting shaft 21 is fixed between the fixing plates 20, the torsion spring 22 is sleeved on the connecting shaft 21, and the second clamping plate 23 is sleeved on the connecting shaft 21.

[0034] After the first clamping plate 16 and the second clamping plate 23 are clamped, the clamping surfaces are on the same plane;
[0035] The fixed plate 20 plays a supporting role, the connecting shaft 21 facilitates the rotation of the second clamping plate 23, and the torsion spring 22 has a reset function, so that the initial position of the second clamping plate 23 remains tilted, which is convenient for inserting the copper foil.

[0036] Working principle:
[0037] Before starting the test, the second clamping plate 23 is acted upon by the torsion spring 22 and remains in an inclined state. One end of the copper foil is inserted between the two semicircular rubber blocks 25 in the square through hole 24 so that one end of the copper foil extends between the U-shaped support frame 14 and the first clamping plate 16. The adjusting knob 15 is turned to drive the first clamping plate 16 to move and clamp the copper foil. At this time, the second clamping plate 23 is restricted by the side of the U-shaped support frame 14 and rotates around the connecting shaft 21 on the fixed plate 20 as the first clamping plate 16 moves until the copper foil is clamped.
