Description

Technical Field

[0001] This application relates to the field of flame retardant testing equipment technology, and in particular to a glow wire testing device that is easy to adjust. Background Technology

[0002] Components in electronic and electrical equipment may be exposed to thermal stress due to electrical effects, and their deterioration may reduce the safety performance of the equipment. Therefore, components are usually subjected to glow wire testing before being put into use. This test simulates the burning of the outer casing by a heat source or ignition source under fault or overload conditions to assess the fire hazard of the product. However, existing glow wire testing machines are designed with fixtures that cannot flexibly change the relative position of the workpiece and the glow wire during use. This results in the need for frequent disassembly and adjustment of the installation position of the workpiece and the glow wire, which seriously affects the testing efficiency of the workpiece. Utility Model Content

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0018] Example

[0019] To address the aforementioned technical problems, this embodiment provides an easily adjustable glow wire testing device, such as... Figure 1 As shown, the device includes a chassis 10, on which a glow wire assembly 20 is mounted. An adjustable clamping assembly 30 is also mounted on the other side of the chassis 10 opposite the glow wire assembly 20. A buffer assembly 40 is also mounted on the side of the glow wire assembly 20 facing the adjustable clamping assembly 30. By mounting the glow wire assembly 20 and the adjustable clamping assembly 30 on the chassis 10, the installation position of the workpiece relative to the glow wire can be adjusted via the adjustable clamping assembly 30, thereby adjusting the contact point between the glow wire and the workpiece to adapt to the testing requirements of different workpieces. Furthermore, the buffer assembly 40 on the side of the glow wire assembly 20 facing the adjustable clamping assembly 30 reduces the contact pressure between the glow wire and the workpiece, preventing damage to the glow wire during operation. This allows for flexible adjustment of the contact point between the glow wire and the workpiece to adapt to the testing requirements of different workpieces, effectively improving the efficiency of the glow wire burning test.

[0020] Specifically, such as Figure 2As shown, the glow wire assembly 20 includes a first mounting base 21 disposed on the chassis 10. The first mounting base 21 is provided with a copper pillar assembly 22 for mounting the glow wire. The first mounting base 21 is also provided with a first driving assembly 23 whose driving end is connected to the copper pillar assembly 22. By providing the copper pillar assembly 22 on the first mounting base, the glow wire can be positioned and limited by the copper pillar assembly 22. Furthermore, by providing the first driving assembly 23 on the first mounting base 21 whose driving end is connected to the copper pillar assembly 22, the installation height of the glow wire can be adjusted by the first driving assembly 23.

[0021] In the above scheme, the glow wire assembly 20 also includes several sets of insertion holes 24 opened in the copper pillar assembly 22. The glow wire is detachably installed in the copper pillar assembly 22 through the insertion holes 24. By opening several sets of insertion holes 24 in the copper pillar assembly 22 along the lifting direction, the glow wire can be installed in the corresponding insertion hole 24 according to the test requirements, thereby further precisely adjusting the installation height of the glow wire.

[0022] Furthermore, the adjustable clamping assembly 30 includes a second mounting base 31 slidably disposed on the chassis 10. A slide rail 32 is provided on the second mounting base 31 along a direction perpendicular to the hot wire mounting direction. A clamping assembly 33 is slidably disposed on the slide rail 32. A second drive assembly 34 is also connected to the side of the second mounting base 31 away from the hot wire assembly 20. By slidably disposing of the second mounting base 31 on the chassis 10, and providing a slide rail 32 along the second mounting base 31 perpendicular to the hot wire mounting direction, and slidably disposing of the clamping assembly 33 on the slide rail 32, the clamping assembly 33 can be used to clamp the workpiece. The workpiece is clamped and fixed, and then the second mounting base 31, on which the clamping component 33 is placed, is driven by the second driving component 34 to slide along the slide rail 32, thereby adjusting the relative position of the workpiece with respect to the contact point of the hot wire. Furthermore, since the second mounting base 31 is also connected to the side away from the hot wire component 20, the second driving component 34 can drive the second mounting base 31 to move closer to or away from the hot wire component 20, thereby driving the workpiece to approach and contact the hot wire, completing the hot wire burning detection, and realizing the adjustment of the installation position of the workpiece by driving the second mounting base 31 along the slide rail 32.

[0023] To limit and fix workpieces of different sizes, in a preferred embodiment, the clamping assembly 33 includes a clamping base 331 slidably disposed on the second mounting base 31. The clamping base 331 has a guide groove 332 for accommodating the workpiece. A clamping plate 333 is slidably disposed in the clamping base 331 within the guide groove 332. A first push rod 334 threadedly connected to the clamping plate 333 is also provided on the side of the clamping base 331. By providing a guide groove 332 for accommodating the workpiece in the clamping base 331, a clamping plate 333 slidably disposed in the clamping base 331 within the guide groove 332, and a first push rod 334 threadedly connected to the clamping plate 333 on the side of the clamping base 331, the clamping plate 333 can be driven to slide along the guide groove 332 by the first push rod 334, thereby clamping and fixing the workpiece placed in the guide groove 332, thus achieving the adaptation and limitation of fixing workpieces of different sizes.

[0024] Specifically, the buffer assembly 40 includes a second push rod 41 disposed on the side of the first mounting base 21 facing the adjustable clamping assembly 30. A top plate 42 is fixedly disposed on the end face of the second push rod 41. An elastic element 43 is also sleeved on the outer periphery of the second push rod 41. The two ends of the elastic element 43 abut against the top plate 42 and the side wall of the first mounting base 21, respectively. By disposing of the second push rod 41 on the side of the first mounting base 21 facing the adjustable clamping assembly 30, fixing the top plate 42 on the end face of the second push rod 41, and sleeved on the outer periphery of the second push rod 41, in this solution, when the second mounting base 31 moves the workpiece close to the hot wire, the second mounting base 31 contacts the top plate 42 before the workpiece, thereby effectively reducing the contact pressure between the hot wire and the workpiece and preventing the hot wire from being damaged due to excessive impact force under high temperature conditions during operation.

[0025] In the above scheme, a chip suction head 11 is suspended at the top of the chassis 10, and an adsorption channel 12 extending to the chip suction head 11 is provided in the chassis 10. An air extraction device is connected to the adsorption channel 12. When the hot wire performs a burning test on the surface of the workpiece, the flue gas generated by the combustion can be extracted by the air extraction device connected to the chip suction head 11, so as to avoid the flue gas polluting the working environment inside the chassis and affecting the observation results of the burning experiment. This achieves the discharge of the flue gas generated by the combustion and avoids the flue gas affecting the experimental observation results.

[0026] Furthermore, a scale 335 is fixedly installed on one side of the clamping base 331. By fixing the scale 335 on one side of the clamping base 331, when the workpiece is burned by the hot wire, the height of the flame generated can be quantified by observing the scale 335, thereby judging the safety of the workpiece application.

[0027] In summary, in one or more embodiments of this application, this application provides an easily adjustable glow wire testing device, including a glow wire assembly mounted on a chassis, an adjustable clamping assembly mounted on the other side of the chassis opposite the glow wire assembly, and a buffer assembly mounted on the side of the glow wire assembly facing the adjustable clamping assembly. By mounting the glow wire assembly and the adjustable clamping assembly on the chassis, the installation position of the workpiece relative to the glow wire can be adjusted via the adjustable clamping assembly, thereby adjusting the contact point between the glow wire and the workpiece to adapt to the testing requirements of different workpieces. Furthermore, by mounting the buffer assembly on the side of the glow wire assembly facing the adjustable clamping assembly, the contact pressure between the glow wire and the workpiece can be reduced, preventing damage to the glow wire during operation. This allows for flexible adjustment of the contact point between the glow wire and the workpiece to adapt to the testing requirements of different workpieces, effectively improving the efficiency of glow wire testing.
