[0036] In the use process, the temperature in the tinning groove of the existing copper wire tinning equipment is always maintained between 280-300 degrees during use, and a warning can be given when the temperature exceeds the corresponding tinning temperature, and the tin slag generated during tinning can be conveniently cleaned.In this embodiment, the personnel first place the slag collecting piece 8 in the tinning groove 3, and due to the limiting of the contraction assembly 7, the slag collecting piece 8 is not at the same horizontal plane as the table surface of the tinning furnace 2.At this time, the personnel press the two sides of the slag collecting piece 8 to make the contraction assembly 7 move downward and be positioned, so that the slag collecting piece 8 is completely embedded in the tinning groove 3, so that the tin slag generated during the subsequent tinning of the copper wire can fall into the slag collecting piece 8 for collection for subsequent processing.

[0037] In this embodiment, the tinning water can be continuously heated and temperature-controlled under the action of the heating piece 4 and the constant temperature controller 9.If the temperature of the tinning water is higher than 300 degrees, the temperature sensed by the deformation support 5 reaches the phase transition point, so the deformation support 5 is stretched, the slag collecting piece 8 originally embedded in the tinning groove 3 is pushed up, and the personnel are warned that the temperature has exceeded the normal temperature during tinning and is likely to cause insulation blistering.The personnel can disconnect the power supply in time and check the equipment without performing the copper wire tinning operation.

[0038] In this embodiment, the deformation support 5 is made of shape memory alloy material, and its phase transition point is 300 degrees.When the temperature is higher than 300 degrees, the deformation support 5 is stretched to push up the slag collecting piece 8.When the temperature is lower than the critical point of 300 degrees, the deformation support 5 returns to the initial shape.

[0041] In use, the constant temperature controller 9 adopts a WJB liquid expansion type adjustable knob temperature controller, which can promote temperature sensing and control of the heating rod 44 through the temperature sensor 45 when the heating rod 44 is electrically heated, so as to ensure that the electric heating temperature is maintained between 280-300 degrees, wherein the heating rod 44 actively heats, and the heat of the heat-conducting silica gel pad 46 is transmitted to promote the surface of the heat-conducting plate 47 to be continuously heated, thereby heating the tinning water in the tinning tank 3.

[0042] Please refer to Figures 1-2 and Figures 4-5 The contraction assembly 7 comprises a setting base plate 71 embedded and mounted in the tinning furnace 2, a movable plate 72 is slidingly connected between the inner walls of the setting base plate 71, a contraction rod 73 is fixedly connected to one side of the movable plate 72, the contraction rod 73 is located between the inner walls of the through hole 6, a stand 74 is fixedly connected to the top end of the movable plate 72 and the side wall of the setting base plate 71, a spring 75 is sleeved between the inner walls of the two stands 74, a limiting block one 76, a limiting block two 77 and a limiting block three 78 are sequentially mounted on the side wall of the movable plate 72 from top to bottom, a limiting rod 79 is rotationally connected to the inner bottom end of the setting base plate 71, and the other end of the limiting rod 79 is located between the inner walls of the movable plate 72.

[0043] More specifically, the limiting block one 76 is located at the top center end of the movable plate 72, the limiting block two 77 is located at the center of the movable plate 72 and is provided with a notch corresponding to the limiting block one 76 at the upper end and an inclined surface at the bottom, and the limiting block three 78 is located at the bottom side of the movable plate 72 and is in close contact with the inner walls of the setting base plate 71.

[0044] In the use process of the scheme, when the personnel install the slag collecting piece 8, the slag collecting piece 8 can be directly pressed to drive the contraction rod 73 to move the movable plate 72 downward, and as the movable plate 72 continuously moves downward, the slide on the side wall of the movable plate 72 is divided into two sides, one side is provided with a slope, and the other side is provided with a straight line, and the height is lower than the highest point of the opposite slope, so that when the movable plate 72 moves downward, the limiting rod 79 can only slide along the inclined surface of the limiting block three 78 and the limiting block two 77, and finally fall into the gap of the limiting block two 77 in the straight slide to be limited, at this time, the contraction rod 73 is in the same horizontal plane with the top surface of the through hole 6, and the slag collecting piece 8 can be completely embedded in the tinning tank 3, so as to carry out the tinning operation of the copper wire.

[0047] In the use process of the scheme, under the action of the liquid permeable holes one 83 and the liquid permeable holes two 84, when the personnel take the slag collecting frame 81 to clean the tin slag inside, the tinning water can be released from the slag collecting piece 8 more quickly, so as to speed up the processing efficiency of the tin slag.

[0048] The above-described embodiments only express certain implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the present application; it should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, the protection scope of the present application patent should be subject to the appended claims.
