Description

Thick film tensile tester

The present invention relates to a tensile testing device, and more particularly to a thick film tensile testing device.

The "tension testing machine" disclosed in Japanese Patent Laid-Open No. M329769 is composed of a base, a power unit, a cylinder, a joint plate, an upper clamp assembly, a lower clamp assembly, a signal processor and a microcomputer computer. It is used to test the tensile force of materials. However, the above-mentioned tensile testing machine is not only complicated in structure, but also structurally unable to perform tensile testing on thick film materials.

The main object of the present invention is to provide a thick film tensile testing device, which comprises a device body, a control unit disposed in the device body, and a test unit disposed on the device body, the test unit being electrically Connecting the control unit, and the test unit includes at least a bearing fixed to the upper portion of the device body, a tension detecting device fixed to the upper bearing seat, and a film fixing seat mounted on the tensile force detecting device. a lifting base disposed opposite to the film fixing seat, the film fixing seat is disposed between the tension detecting device and the lifting base, and the invention can be used for testing the tensile strength of the dielectric film of the laminated ceramic capacitor, and It has the advantages of low cost, simple operation and high accuracy.

1 and 2 are a preferred embodiment of the present invention. A thick film tensile testing device includes a device body 10, a control unit 20 disposed in the device body 10, and a device disposed on the device. In the present embodiment, the test unit 30 is electrically connected to the control unit 20, and the control unit 20 controls the action of the test unit 30, and the test unit 30 includes at least There is a bearing 31 fixed to the upper portion of the device body 10, a tension detecting device 32 fixed to the upper bearing seat 31, a film fixing seat 33 mounted on the tensile force detecting device 32, and a film fixing seat. In the embodiment, the tension detector 32 has a hook 32a, and the film holder 33 can be hung on the hook 32a of the tension detector 32. The membrane holder 33 is replaced by a different size, and the membrane holder 33 is disposed between the tension detector 32 and the lifting base 34, and the membrane holder 33 has a first bonding surface. 33a, the first bonding surface 33a is for one end of a thick film to be tested (Fig. Drawings 1 and 3, the lifting base 34 has a second bonding surface 34a, and the second bonding surface 34a is suitable for the other end of the thick film to be tested. In this embodiment, the first bonding surface 33a of the film holder 33 is flush with the second bonding surface 34a of the lifting base 34 such that the direction of the force application is on the same plane. Improve test accuracy.

Referring to FIGS. 1 and 2 again, in the embodiment, the test unit 30 further includes a pair of guiding rods 35 and a constant temperature heating mechanism 36. Each of the guiding rods 35 extends through the lifting base 34 to guide the lifting and lowering. The base 34 is vertically lifted. In addition, each of the guide rods 35 has a stop portion 35a. In the embodiment, each of the stop portions 35a can limit the lift base 34 to prevent the lift base 34 from colliding with the lift base 34. The thermostat heating mechanism 36 has a cavity 361 and a thermostat heater 362. The cavity 361 is fixed to the device body 10. The thermostat heater 362 is disposed in the cavity 361. In the present embodiment, the film holder 33 and the lifting base 34 are located in the cavity 361 of the constant temperature heating mechanism 36 to maintain the temperature in the cavity 361 at a specific test temperature. The thick film to be tested can be subjected to a tensile test under a specific temperature environment. The thick film tensile testing device of the invention can be used for testing the tensile strength of a dielectric film of a laminated ceramic capacitor, and has the advantages of low cost, simple operation and high accuracy.

The scope of the present invention is defined by the scope of the appended claims, and any changes and modifications made by those skilled in the art without departing from the spirit and scope of the invention are within the scope of the present invention. .
