Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, specifically to a multi-directional tensile testing device for silver layer bonding strength. Background Technology

[0002] "Silver layer" usually refers to a thin film or coating of metallic silver formed on the surface of a substrate material. Due to the unique physical and chemical properties of silver, it has a wide range of applications in many fields. It usually requires the densification of silver particles through sintering equipment to enhance the bonding strength. To ensure the bonding strength of the silver layer, it is usually necessary to test it through a tensile testing device.

[0003] Currently, tensile testing devices lack multi-directional adjustment mechanisms, typically only capable of testing tensile forces in a single direction. However, the direction of force may vary depending on the working environment, resulting in limited flexibility and accuracy in practical use. Therefore, this paper proposes a multi-directional tensile testing device for silver layer bonding strength to incorporate a multi-directional adjustment mechanism. By utilizing rotation and guidance, it enables multi-directional tensile testing, improving not only the device's performance but also the accuracy of test data. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To facilitate multi-directional tensile testing using rotation and guidance methods, thereby improving usability, such as... Figure 1-3 As shown, the multi-directional tensile testing device for silver layer bonding strength of this utility model includes a frame 1, a guide assembly 2, and a protective assembly 7. The guide assembly 2 is provided on the surface of the frame 1, and a first clamp assembly 4 is slidably connected to the surface of the guide assembly 2. An electric slide rail 5 is bolted to the bottom of the frame 1, and a second clamp assembly 6 is slidably connected to the top of the electric slide rail 5. The protective assembly 7 is provided on the top of the first clamp assembly 4.

[0025] The guide assembly 2 includes a rotating frame 201, and the rotating frame 201 is mounted on the frame 1 via bearings. A stepper motor 101 is bolted to the back of the frame 1, and the stepper motor 101 is connected to the rotating frame 201 via a drive shaft.

[0026] In use, the frame 1, electric slide rail 5, rotating frame 201, and stepper motor 101 can be used to add a multi-directional adjustment mechanism. By using rotation, sliding, and guiding methods, the tensile testing direction and angle of the workpiece can be adjusted to achieve the function of multi-directional tensile testing.

[0027] The electric slide rail 5 includes a slide base.

[0028] Both the first clamp 402 and the second clamp 602 are pneumatic grippers.

[0029] To improve operational safety, for example, such as Figure 2 , Figure 4 As shown, the present invention also includes the following: the protective component 7 includes a fixing frame 701, a tension sensor 403 is provided on the top of the fixing frame 701, an installation groove 702 is provided in the fixing frame 701, a rotating roller 703 is rotatably connected in the installation groove 702, a transparent PET protective film 704 is wound around the outer periphery of the rotating roller 703, and protective plates 3 are bolted to both sides of the surface of the rotating frame 201 located on the first clamping component 4, and a slide rail 301 is provided on the inner side of the protective plate 3.

[0030] When in use, the auxiliary protective mechanism can be added through the fixing frame 701, mounting groove 702, rotating roller 703, transparent PET protective film 704 and protective plate 3. While the tensile test is being conducted, the protective structure is deployed around the silver layer, thereby improving the safety during the test. One end of the transparent PET protective film 704 is provided with a locking strip.

[0031] For example, such as Figure 2 As shown, the present invention also includes a lead screw 202 installed in the rotating frame 201 via a bearing, a corresponding ball block 203 sleeved around the lead screw 202, a reduction motor 204 connected to the top of the rotating frame 201 via bolts, and the reduction motor 204 connected to the lead screw 202 via a drive shaft.

[0032] In use, the ball screw 202, ball slider 203 and geared motor 204 can be used to control and adjust the displacement of the first clamp assembly 4 to perform tensile testing. The ball slider 203 is connected to the mounting bracket 401 by bolts.

[0033] For example, such as Figure 4 As shown, the present invention also includes a rotating shaft 705 at both ends of the rotating roller 703 by bolts, and the rotating roller 703 is rotatably connected to the mounting groove 702 through the rotating shaft 705. A coil spring 706 is sleeved around the rotating shaft 705, and one end of the coil spring 706 is welded to the rotating shaft 705, and the other end of the coil spring 706 is connected to the mounting groove 702 through a slot.

[0034] In use, the rotating shaft 705 and the coil spring 706 facilitate the use of elastic force to drive the rotating roller 703 to reset and rotate after the tensile test is completed, thus performing the recycling action.

[0035] For example, such as Figure 3 As shown, the present invention also includes the first clamp assembly 4, which includes a mounting frame 401. The top of the mounting frame 401 is connected to a fixing frame 701 by bolts, and the mounting frame 401 is slidably connected to a slide rail 301 by sliders on both sides. The bottom of the mounting frame 401 is connected to a first clamp 402 by bolts.

[0036] In use, the mounting bracket 401 and the first clamp 402 facilitate the movement of the workpiece for tensile testing.

[0037] For example, such as Figure 5 As shown, the present invention also includes the second clamp assembly 6, which includes a base 601. The top of the base 601 is connected to the second clamp 602 by bolts. A limiting slot 603 is formed on the surface of the top of the base 601 on the outside of the second clamp 602, and one end of the transparent PET protective film 704 is connected to the limiting slot 603 by a slot.

[0038] In use, the base 601 and the second clamp 602 facilitate the clamping and tensile testing of the first clamp 402. The limiting slot 603 facilitates the fixing of one end of the transparent PET protective film 704. The base 601 is connected to the slide of the electric slide rail 5 by bolts.

[0039] In use, the operator first manually starts the stepper motor 101 to drive the rotating frame 201 to rotate according to the actual tensile test direction, adjusts the use angle of the first clamp 402, and then drives the base 601 to slide through the slide of the electric slide rail 5 to adjust the use position of the second clamp 602. Next, the workpiece is placed between the first clamp 402 and the second clamp 602 to clamp and fix both ends. Then, the clip of one end of the transparent PET protective film 704 is pulled out from the fixing frame 701 and inserted into the limiting slot 603 for fixation. Then, the operator manually starts the reduction motor 204 to drive the lead screw 202 to rotate, and uses the ball slider 203 to drive the mounting frame 401 to slide. The tensile sensor 403 is used to perform tensile test on the workpiece.

[0040] Moreover, while the first clamp 402 moves to perform the tensile test, the transparent PET protective film 704 can gradually form a protective covering structure around the clamp. Together with the protective plate 3, it can form an auxiliary protective structure, which can avoid the safety hazards caused by brittle fracture during the tensile test, thereby improving the safety and stability of the device and making it more flexible and reliable to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
