Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weighing sensor processing, in particular to a welding device for a weighing sensor. Background Art
[0002] As an important component of modern industrial measurement and control, weighing sensors are widely used in various weighing, force measurement, counting and other occasions. The sophistication of their manufacturing process directly determines the performance and measurement accuracy of the sensor. In the processing of weighing sensors, the welding of electrode leads is also extremely important.
[0003] When welding the electrode leads of existing weighing sensors, special welding equipment is usually not used. Instead, the electrode leads are manually held and connected to the wires before welding. However, since the handheld electrode leads are prone to shaking during welding, it is difficult to keep the leads stable during welding, resulting in the leads being easily dislocated and broken during welding. In addition, when welding the electrode leads of the weighing sensor, since the welding temperature range is unknown, the welding point of the leads is more likely to be overheated, resulting in a larger heat affected zone during welding. Utility Model Content
[0004] The purpose of the utility model is to provide a welding device for a weighing sensor to solve the problems raised in the above background technology.

[0011] Preferably, the electric clamp is movably connected to one end of the wire through a wire tube.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The welding device of the weighing sensor can clamp one end of the electrode lead on the sensor on the device through the electric clamp, the wire tube, the cross plate and the bayonet. At the same time, the end of the wire that needs to be welded with the electrode lead can also be clamped on the device, and one end of the electrode lead and one end of the wire can be tightly attached and kept in a static state, thereby reducing the probability of misalignment and breakage of the motor lead during welding.
[0014] 2.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figures 1 to 4 As shown, the welding device of the weighing sensor of this embodiment includes a sleeve 1, a sensor body 13 is placed inside the sleeve 1, one end of the sensor body 13 is electrically connected to the electrode lead 14, a horizontal plate 7 is fixedly connected to the middle of the inner wall of the sleeve 1, a partition 3 is provided on one side of the sleeve 1, a thermal test paper 2 is clamped on the top of the front side of the partition 3, a bayonet 5 is opened on the front side of the partition 3, a bracket 11 is fixedly connected to the bottom of one side of the sleeve 1, one end of the bracket 11 is fixedly connected to the wire tube 12, the inner side of the wire tube 12 is slidably connected to the wire 15, and an electric clamp 9 is provided on the top of the bracket 11.
[0024] Specifically, the top and both sides of the sleeve 1 are not closed, so that the weighing sensor can be quickly placed in the sleeve 1 for limit fixing, and at the same time, the electrode lead 14 of the weighing sensor can be placed on the notch 8 of the horizontal plate 7 to wait for clamping. The function of the horizontal plate 7 is to support the electrode lead 14, so that the electrode lead 14 can be at the same horizontal height as the wire 15 in the traction tube after being clamped by the device, thereby facilitating the close contact between the electrode lead 14 and the wire 15, which is beneficial to subsequent welding. The partition 3 is made of a material with good thermal insulation performance, so that the heat radiation generated during welding is not easy to cause adverse effects on the weighing sensor body 13. The thermal test paper 2 generates a chemical reaction on the test paper through thermal energy control, thereby producing different color changes, which can reflect the test paper. The heat or temperature level to which the paper is exposed, so that the user can know the temperature during welding in time, the function of the bayonet 5 is to cooperate with the notch 8 to clamp the electrode lead 14 on the notch 8, so as to facilitate the welding of the electrode lead 14 and the wire 15, the function of the bracket 11 is to support the wire drawing tube 12, so that the wire drawing tube 12 can be at the same horizontal height as the cross plate 7, the top of the wire drawing tube 12 is cut and opened, so that the wire 15 can be quickly placed in the wire drawing tube 12, which is convenient for the user to operate, and the function of the electric clamp 9 is to be able to pull the end of the wire 15 out of the wire drawing tube 12, so that the end of the wire 15 can be moved to a position that fits the electrode lead 14, so as to facilitate the subsequent welding of the electrode lead 14 and the wire 15.
[0025] Furthermore, a first guide rail 6 is installed on one side wall of the sleeve 1, and the partition 3 is engaged with the slider on the first guide rail 6. The partition 3 is movably connected to the sleeve 1 through the first guide rail 6. The first guide rail 6 is a linear guide rail, which is composed of a slider and a guide rail. It is controlled by an editable program so that the partition 3 can slide up and down along one side of the sleeve 1 driven by the first guide rail 6, thereby realizing the clamping of the electrode lead 14 by the bayonet 5 and the notch 8.
[0026] Furthermore, a rubber strip 4 is engaged with the inner wall of the bayonet 5, a notch 8 is opened in the middle of the cross plate 7, and the bayonet 5 is movably connected to the notch 8 through the partition 3. The function of the rubber strip 4 is to reduce the friction between the bayonet 5 and the electrode lead 14, thereby reducing the wear of the electrode lead 14.
[0027] Furthermore, the electrode lead 14 is movably connected with the notch 8 and the bayonet 5 , and the electrode lead 14 can be clamped by the notch 8 and the bayonet 5 at the same time, thereby maintaining a static state, so that it can be smoothly and tightly docked with one end of the wire 15 clamped by the electric clamp 9 .
[0028] Furthermore, the bottom end of the electric clamp 9 is fixedly connected to a vertical rod 16, and the top of the bracket 11 is installed with a second guide rail 10, which is also a linear guide rail, and can drive the vertical rod 16 to slide left and right at the top of the bracket 11, thereby realizing the traction of the electric clamp 9 on the wire 15.
[0029] Furthermore, the slider on the second guide rail 10 is engaged with the bottom end of the vertical rod 16, and the electric clamp 9 is movably connected to the bracket 11 through the second guide rail 10. The electric clamp 9 moves left and right on the top of the bracket 11 through the vertical rod 16, so that the end of the wire 15 can be quickly docked with the end of the electrode lead 14, thereby facilitating subsequent welding.
[0030] Furthermore, the electric clamp 9 is movably connected to one end of the wire 15 through the wire tube 12. The electric clamp 9 can clamp the wire 15 led out from the end of the wire tube 12, thereby fixing the end of the wire 15 and increasing the stability of the wire 15 during welding.
[0031] The method of using the present embodiment is as follows: when using the welding device of the weighing sensor, the device needs to be connected to an external power supply first, and then the weighing sensor can be placed in the sleeve 1, and then the electrode lead 14 at one end of the sensor is placed on the notch 8 of the horizontal plate 7, and then the first guide rail 6 is controlled to drive the partition 3 to slide down, so that the bayonet 5 on the partition 3 moves toward the electrode lead 14 on the notch 8, until the rubber strip 4 on the bayonet 5 contacts the electrode lead 14, and the electrode lead 14 will be clamped by the notch 8 and the bayonet 5. At this time, the partition 3 separates the weighing sensor and the electrode lead 14, and then the wire 15 is passed through the wire tube 12, and the end of the wire 15 is passed through the electric clamp 9, and then the electric clamp 9 is started. Clamp the end of the wire 15, then control the second guide rail 10 to drive the vertical rod 16 and the electric clamp 9 to move toward one end of the clamped electrode lead 14 until the end of the electrode lead 14 coincides with the end of the wire 15. Then, an electric welding pen can be used to weld the electrode lead 14 and the wire 15. The heat generated during the welding process will be absorbed by the thermal test paper 2. The user can check the color changes on the thermal test paper 2 at any time. When the temperature range reflected by the color change on the thermal test paper 2 exceeds the set temperature range, the temperature of the electric welding pen needs to be adjusted. At the same time, the heat generated during welding will be mostly blocked by the partition 3, so that the weighing sensor in the kit 1 is not easily affected by the heat during welding.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
