[0038] Further, an antiskid layer is arranged on the clamping surface 8 of the clamping block 7.

[0039] The working principle of the above technical scheme is as follows: the two surfaces of the ceramic substrate require a certain parallelism, the surface of the ceramic substrate with high parallelism is more flat, which is beneficial to surface treatment (such as cleaning, polishing, etc.) and coating (such as electroplating, spraying, etc.), thereby improving the appearance and durability of the product. The ceramic substrate is often used in high-density and high-precision packaging structures. The requirement of parallelism can ensure the accurate butt joint of the substrate with other elements in the packaging process, thereby improving the reliability and performance of packaging. The parallelism of the two surfaces of the ceramic substrate is high, so when the ceramic substrate is clamped, the parallelism of the clamping surface in contact with the ceramic substrate is ensured, so that the clamping surface is uniformly in contact with the surface of the ceramic substrate.

[0040] The power box 2, the moving plate 4 and the fixed plate 3 are sequentially arranged on the top surface of the workbench 1, the power box 2 and the fixed plate 3 are fixedly arranged at two ends of the length direction of the top surface of the workbench 1, the moving plate 4 and the fixed plate 3 are both arranged perpendicularly to the length direction of the workbench 1, a sliding groove 9 is formed on the top surface of the workbench 1 along the length direction of the workbench, a sliding block is fixedly arranged on the bottom surface of the moving plate 4 at a position corresponding to the sliding groove 9, the sliding block is slidingly arranged in the sliding groove 9, so that the moving plate 4 can move along the length direction of the workbench 1, and two sliding grooves 9 can be parallelly arranged, which can increase the stability of the moving plate 4 during movement.

[0041] The clamp head 5 is fixedly arranged on the opposite side surface of the fixed plate 3 and the moving plate 4, a wedge-shaped groove 6 is formed on the opposite side surface of the two clamp heads 5, a wedge-shaped slot 10 is formed on the inclined surface of the wedge-shaped groove 6 along the length direction of the inclined surface, and a wedge-shaped sliding rail 11 is slidingly arranged in the wedge-shaped slot 10 on the clamping block 7, so that the clamping block 7 can move along the inclined surface of the wedge-shaped groove 6, the clamping block 7 is a wedge-shaped block, the inclined surface and the inclination angle of the wedge-shaped block of the clamping block 7 are the same as the inclination angle of the inclined surface of the wedge-shaped groove 6, so that the clamping surface 8 is always parallel to the length direction of the workbench 1 during the movement of the clamping block 7, the moving plate 4 also moves along the length direction of the workbench 1 during movement, and the ceramic substrate can only bear the tension along the length direction of the workbench 1 during tension, thereby ensuring the accuracy of the tensile detection.

[0042] In the process of the tensile test of the ceramic substrate, one end of the ceramic substrate is first rotated to the middle of the two clamping blocks 7 of the clamping head 5 on the fixed plate 3, the hand wheel 17 outside the fixed plate 3 is rotated to drive the screw rod 14 to rotate, the screw rod 14 is threadedly connected with the threaded hole 15 of the bottom plate of the clamping head 5, the screw rod 14 drives the connecting plate 13 to move to the opening end of the wedge-shaped groove 6 when rotating, the connecting plate 13 drives the two clamping blocks 7 to move to the opening end of the wedge-shaped groove 6, and the opening end of the wedge-shaped groove 6 is small in size, so that the two clamping blocks 7 are close to each other during the movement, and the ceramic substrate located in the middle of the two clamping blocks 7 is clamped. During the process that the connecting plate 13 drives the clamping blocks 7, the connecting groove 12 of the clamping block 7 slides with the connecting plate 13, then the motor 19 is started, the moving plate 4 is driven to move to the appropriate position by the lead screw 20, the motor 19 is turned off, then the hand wheel 17 outside the moving plate 4 is rotated, and the two clamping blocks 7 of the clamping head 5 on the moving plate 4 clamp the other end of the ceramic substrate by the same principle, then the motor 19 is started, the moving plate 4 moves away from the fixed plate 3, and the ceramic substrate is pulled off until the tensile test is completed. After the test is completed, the hand wheel 17 is reversely rotated, and the ceramic substrate clamped in the middle of the clamping blocks 7 can be taken out. During the tensile test of the ceramic substrate, a batch of ceramic substrates can be sampled and tested, and the specific sampling method can be determined according to the needs.

[0044] The end of the connecting groove 12 close to the side wall of the bottom surface of the wedge-shaped groove 6 is provided with a semicircular groove 18, which is located away from the screw rod 14, so as to prevent the screw rod 14 from being stuck in the clamping blocks 7 during the process that the clamping blocks 7 are close to each other, and the radius of the semicircular groove 18 is greater than the radius of the screw rod 14.
