Description

Technical Field

[0001] This utility model relates to the field of diamond wire saw technology, and in particular to a handheld tension meter calibration device. Background Technology

[0002] Diamond wire saws are widely used in silicon wafer cutting. They are a crucial component in the process, and wire breakage during cutting severely impacts the quality of the cut. Insufficient rewinding tension after the diamond wire is removed from the wire can lead to wire sparseness and compression, significantly increasing the breakage rate during silicon wafer cutting. After a breakage, repeated rewinding is required, increasing labor intensity, reducing cutting efficiency, and further affecting the cut quality.

[0003] Therefore, the tension during diamond wire saw rewinding needs to be controlled within a certain safe range, and the tension needs to be calibrated regularly. In this field, a handheld tension meter is commonly used as the instrument for tension calibration, and its own error is particularly important.

[0004] However, handheld tension gauges are usually not equipped with relevant calibration devices to calibrate themselves. Therefore, there is an urgent need in the field for a device that can calibrate the accuracy of the handheld tension gauge to meet the production requirements of diamond wire saws. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides a handheld tension meter calibration device, including a bracket, a placement plate, a locking component, a boom, a suspension line, and weights;

[0007] The placement plate and the locking member are both provided on the bracket. The placement plate and the locking member are arranged opposite to each other. The placement plate is used to place the handheld tension meter, and the locking member is used to fix and lock the handheld tension meter to the placement plate.

[0008] One end of the boom is connected to the bracket, the other end of the boom is connected to one end of the suspension line, and the end of the suspension line away from the boom is connected to the weight.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown in the figure, the present invention provides a handheld tension meter calibration device, including a bracket 1, a placement plate 2, a locking component 3, a lifting arm 4, a suspension line 5, and a weight 6.

[0022] The placement plate 2 and the locking member 3 are both fixedly mounted on the bracket 1. The placement plate 2 and the locking member 3 are arranged opposite to each other. The placement plate 2 is used to place the handheld tension meter, and the locking member 3 is used to fix and lock the handheld tension meter to the placement plate 2. The placement plate 2 and the locking member 3 together limit the handheld tension meter to prevent it from moving.

[0023] One end of the boom 4 is connected to the bracket 1, and the other end of the boom 4 is connected to one end of the suspension line 5. The end of the suspension line 5 away from the boom 4 is connected to the weight 6.

[0024] Based on the above scheme, by placing the handheld tension meter on the placement plate 2 and fixing it with the locking member 3, the suspension wire 5 passes around the pressure wheel of the handheld tension meter. The tension detected by the handheld tension meter is the tension of the suspension wire 5, which is the weight generated by the weight 6 itself. Then, the displayed value of the handheld tension meter is compared with the weight value of the weight 6. If there is an error, the handheld tension meter is calibrated and adjusted. Therefore, the above-mentioned handheld tension meter calibration device can quickly, efficiently, conveniently and accurately achieve the accuracy calibration of the tension meter itself, meeting the usage requirements of electroplated diamond wire production.

[0025] Specifically, the weight 6, for example, is 200g, which generates a tension of 1.96N on the suspension line 5. If the tension value of the suspension line 5 displayed by the handheld tension meter is inaccurate, the value of the handheld tension meter can be adjusted to 1.96N. By using the weight of the standard weight 6 itself to calibrate the handheld tension meter, the structure is intuitive and clear, and the principle is simple and straightforward.

[0026] In some embodiments, the placement plate 2 is provided with a limiting groove 21 for placing a handheld tension meter, and the locking member 3 is a quick clamp, which is located above the placement plate 2. Specifically, the limiting groove 21 on the upper side of the placement plate 2 facilitates the limiting of the handheld tension meter. By pulling the quick clamp downward to press the handheld tension meter, the handheld tension meter can be quickly clamped and fixed.

[0027] In some embodiments, the boom 4 is horizontally arranged, and a gasket 7 is provided at the upper end of the suspension line 5, with the suspension line 5 vertically passing through the boom 4. Specifically, the gasket 7 is fixedly provided at the upper end of the suspension line 5 and located on the upper side of the boom 4. In this way, the gasket 7 can limit the suspension line 5 and prevent the upper end of the suspension line 5 from moving downward.

[0028] In some embodiments, such as Figure 1 As shown, the bracket 1 includes a base 11, an upright plate 12, and an L-plate 13. The upright plate 12 is vertically mounted on the base 11, and the L-plate 13 is connected to both the base 11 and the upright plate 12. The L-plate 13 is used to fix the upright plate 12 on the base 11 to prevent it from moving. The L-plate 13 can be fixedly connected to both the base 11 and the upright plate 12 by means of hexagon socket head cap screws.

[0029] In some embodiments, L-plates 13 are provided on opposite sides of the upright plate 12. The upright plate 12 can be better limited by the two opposite L-plates 13, ensuring the firmness of the connection between the lower end of the upright plate 12 and the base 11.

[0030] In some embodiments, the placement plate 2, the locking member 3, and the boom 4 are all located on the upright plate 12. Specifically, the placement plate 2, the locking member 3, and the boom 4 can all be fixedly connected to the upright plate 12 by means of hexagon socket head cap screws.

[0031] In some embodiments, such as Figure 1 As shown, the handheld tension meter calibration device also includes a pad 8 disposed on the upright plate 12, and a locking member 3 disposed on the pad 8. The locking member 3 is fixed on the pad 8, and the pad 8 is then connected to the upright plate 12 by an internal hex bolt, thereby the locking member 3 is connected to the upright plate 12 through the pad 8.

[0032] In some embodiments, the base 11 is made of carbon steel, while the upright plate 12, L-plate 13, placement plate 2, boom 4 and pad 8 are all made of aluminum alloy. The density of carbon steel is three times that of aluminum alloy, which can greatly reduce the overall center of gravity of the device, reduce the risk of tipping over during use, and make it easy to move and operate flexibly.

[0033] In some embodiments, the suspension line 5 is a fishing line with a diameter of 0.1 mm, which has a low elongation rate and can reduce measurement errors, thereby improving the accuracy of handheld tension meter calibration.

[0034] In summary, this utility model embodiment provides a handheld tension meter calibration device, which can efficiently, conveniently, and accurately achieve rapid calibration of the handheld tension meter. The handheld tension meter is placed on the placement plate 2, and the quick-clamp is operated to tighten and fix it. The suspension wire 5 passes around the tension meter's pressure wheel. At this moment, the tension meter measures the tension of the suspension wire 5, which is the gravity generated by the weight 6. The reading on the tension meter is compared; if there is an error, it can be adjusted to match the gravity of the weight 6 to complete the calibration. This device achieves self-precision calibration of the handheld tension meter, meeting the accuracy requirements in the diamond wire saw production field, reducing the production anomaly rate. Furthermore, this device features small size, low manufacturing cost, maintenance-free operation, high versatility, and ease of use.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
