[0002] In the cable production process, the cable surface needs to be treated with tin.

In order to replenish the tin consumption in the tin tank, it is necessary to arrange special personnel to regularly put tin bars into the tin tank, which leads to the following problems:

[0003] (1) The operator did not put in the tin bar in time, resulting in insufficient tin in the tin tank, and there was no tin amount detection in the tin tank, which would lead to poor tin immersion or burnout of the tin tank;

[0004] (2) In order to quickly fill up the consumed tin material, the operator will put in an excessive amount of tin bars at one time, which will cause the temperature in the tin bath to drop rapidly and fail to meet the process requirements; at the same time, even if the operator puts in tin bars one by one as required, this operation is time-consuming and laborious, and it is difficult to control the amount and speed of tin addition;

[0005] (3) Manual tinning by operators results in a waste of labor, and manual tinning cannot control the actual number of tin bars put in. Manual tinning also poses a risk of burns. Utility Model Content

[0026] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0027] See also Figure 1-Figure 9 The automatic tin-feeding device for high-temperature cable tinning process of the utility model comprises a tin-feeding machine 2 and a tin-dipping machine 1; the tin-feeding machine 2 comprises a frame 4, a tin bar automatic feeding device 5 arranged on the frame 4, a tin bar conveying device 3 for conveying the tin bars in the tin bar automatic feeding device 5 to the tin-dipping machine 1, and a control system, wherein:

[0028] The tin bar automatic feeding device 5 includes a tin bar storage mechanism disposed in the frame 4, a Z-axis driving mechanism 503 for driving the tin bar storage mechanism to move along the Z-axis, and an X-axis driving mechanism 501 for driving the Z-axis driving mechanism 503 to move along the X-axis direction;

[0029] The frame 4 is provided with an opening 402 at a position corresponding to the tin bar handling device 3 ; the tinning machine 1 is provided with a tin bar delivery port 101 , and the tin bar handling device 3 is used to take out the tin bar from the opening 402 and deliver it to the tin bar delivery port 101 .

[0030] See also Figure 1-Figure 9 The tin bar storage mechanism includes a base plate 504 and a plurality of limit rods 505 arranged on the base plate 504, wherein the plurality of limit rods 505 are arranged equidistantly along the width direction of the base plate 504, and the gaps between two adjacent limit rods 505 constitute storage slots for storing tin bars; each limit rod 505 includes a plurality of limit rods 505, and the plurality of limit rods 505 are arranged along the length direction of the base plate 504; under normal circumstances, in order to ensure that the amount of tin does not exceed the minimum range, the operator needs to check the amount of tin in the tin furnace at least once every 10 minutes. According to the consumption of the amount of tin, an average of 60 bars need to be put in each shift, and about 0.3 people / shift are responsible for tinning each production line. The automatic tinning device of the utility model can save about 1 person for every three production lines; in addition, the maximum storage capacity of tin bars in the tin bar storage mechanism of the utility model is 60 bars, a total of 50 kg; this can meet the supply of tin materials for the normal continuous production of the tinning machine 1 for 12 hours, thereby greatly saving labor costs.

[0031] See also Figure 1-Figure 9 , the Z-axis driving mechanism 503 is used to drive the substrate 504 to do lifting movement, and the Z-axis driving mechanism 503 is composed of a Z-axis cylinder / electric cylinder; the X-axis driving mechanism 501 includes an X-axis cylinder / electric cylinder and a movable plate 502, wherein the Z-axis cylinder / electric cylinder is installed on the movable plate 502, the X-axis cylinder / electric cylinder is installed on the frame 4, and the piston rod of the X-axis cylinder / electric cylinder is connected to the movable plate 502; each time the tin bar handling device 3 takes out a tin bar, the Z-axis driving mechanism 503 will drive the tin bar storage mechanism to rise to a certain height (until the sensor located at the opening 402 senses that the tin bar has reached the handling position and stops moving), until all the tin bars in this row (that is, all the vertically arranged tin bars in a group of storage slots) are taken out; then the X-axis driving mechanism 501 drives the Z-axis driving mechanism 503 to translate to the position corresponding to the next row of tin bars, and the Z-axis driving mechanism 503 repeats the action of the previous cycle. During this process, if a power outage occurs, the program in the control system will automatically memorize the current position of the tin bar storage mechanism, and when power is restored, it will continue to maintain the current position.

[0032] In this embodiment, in order to ensure the accuracy of the Z-axis drive mechanism 503, a lifting guide mechanism is arranged between the movable plate 502 and the base plate 504, and the lifting guide mechanism is composed of multiple groups, each group of lifting guide mechanisms includes a guide rod arranged on the movable plate 502 and a guide seat arranged on the base plate 504 and cooperating with the guide rod; similarly, in order to ensure the accuracy of the X-axis drive mechanism 501, a movable guide mechanism may also be arranged between the movable plate 502 and the frame 4, and the movable guide mechanism may adopt a combination of a slide rail and a slider.

[0033] See also Figure 1-Figure 9 The tin bar handling device 3 includes a handling robot 303, a handling lifting mechanism 302 for driving the handling robot 303 to perform lifting motion, and a Y-axis driving mechanism 301 for driving the handling lifting mechanism 302 to move along the Y-axis direction, wherein the handling robot includes a clamping component and a clamping driving mechanism for driving the clamping component to clamp or release, wherein a contact probe 304 is provided on the clamping component, and the clamping driving mechanism can adopt a clamping cylinder / electric cylinder; the handling lifting mechanism 302 and the Y-axis driving mechanism 301 are both composed of electric cylinders.

[0034] The speed of the downward movement of the transport and lifting mechanism 302 is the tinning speed, which needs to be set according to the process requirements to reduce the temperature fluctuation; in order to ensure that the solid tin material melts and reaches the process conditions, the normal working temperature of the tin cylinder is 280℃-300℃. Once the solid tin bar at room temperature is put in too fast, the temperature of the tin material in the tin cylinder will drop rapidly, directly affecting the effect of tinning. Therefore, according to the size (cross-sectional area) of the actual tin material put in, combined with the heating power of the tin cylinder in the tinning machine 1, through multiple groups of experimental tests, the maximum tinning speed of the current tin material is obtained. Under the condition of meeting the stability of the tin surface, the slower the putting speed, the more stable the temperature.

[0035] The clamping assembly is provided with a conductive contact probe 304 (ie, a contact sensor). Once the tin bar slips and causes a clamping error, the contact probe 304 will be conductive, and the equipment will alarm and shut down, reminding the operator to confirm the handling of the equipment.

[0036] See also Figure 1-Figure 9 After the cable passes through the tin furnace heated and melted by the tinning machine 1, a tin layer will adhere to the surface, which will also cause the amount of tin in the tin furnace to decrease, and the tin needs to be replenished manually or with equipment; when replenishing the tin material manually, it is necessary to open the door of the tinning machine 1 and add tin manually, which poses a great risk of scalding; now that the tin bar delivery port 101 is installed, the door of the tinning machine 1 no longer needs to be opened, thereby eliminating the risk of scalding when adding tin.

[0037] See also Figure 1-Figure 9The tinning machine 1 is provided with a tin surface sensing sensor. When the tin surface sensing sensor senses that the tin surface reaches a set height, the tin addition is stopped; when the tin surface sensing sensor senses that the tin surface is lower than the set low level, a signal is sent to the control system, and the control system controls the tin bar handling device 3 to transport and put in the tin bar.

[0038] See also Figure 1-Figure 9 This embodiment realizes the automatic control of the tin-throwing machine 2 and the signal interaction between the tin-throwing machine 2 and the tin-immersing machine 1. When the tin amount in the tin tank is insufficient, the tin-throwing machine 2 automatically adds tin through the signal feedback of the tin amount sensing sensor or the tin surface sensing sensor. During this process, if the tin-throwing machine 2 fails or there is a shortage of material in the tin-throwing machine 2, resulting in the inability to replenish the tin amount in the tin tank of the tin-immersing machine 1 in time, the tin amount sensor signal can be delayed (such as the tin amount sensor signal continues to have no feedback for a certain period of time), output an abnormal signal and alarm, and remind the operator to replenish the tin material or check the equipment status.

[0039] In this embodiment, the tin amount sensing sensor or tin surface sensing sensor can be implemented with reference to the following structure, that is, a pair of metal probes of equal height are installed on the surface of the tin cylinder of the tinning machine 1. Since tin has good conductivity, when the tin surface is submerged by the two metal probes, the two metal probes immersed under the tin surface will generate a short-circuit signal, indicating that the tin surface / tin amount has reached the set requirements, thereby stopping the addition of tin. As the amount of tin is consumed, the tin surface gradually decreases, and the metal probe that was originally turned on is disconnected. The control system will control the tinning machine 1 to start adding tin, and this cycle repeats to achieve automatic tinning to maintain the stability of the tin surface. According to the tolerance range of the tin surface height, the delay control after the metal probe is turned on and off can be increased and adjusted to ensure that the tin surface is controlled within the specified tolerance range.

[0040] See also Figure 1-Figure 9 The working process of the automatic tinning device for high-temperature cable tinning process of the utility model is as follows:

[0041] First, open the chassis door 401 above the soldering machine 2, and place the solder bars in the solder bar storage mechanism according to the specified direction and quantity, and fill it as full as possible while ensuring that the number of solder bars does not exceed the upper limit. Subsequently, close the chassis door 401 above the tin-throwing machine 2, confirm that the electrical system of the tin-throwing machine 2 is normal, and confirm that there are no abnormalities in the settings of various parameters; then press the start button, and the tin-throwing machine 2 starts working; during this process, the tin bar automatic feeding device 5 starts working to transport the tin bar to the designated handling position; when the tin surface detection sensor of the tin cylinder displays the state of the tin surface on the touch screen, when the tin surface reaches the lower limit, the tin bar conveying device 3 reaches the conveying position to clamp the tin bar and slowly rises. At this time, the horizontally placed tin bar will automatically rotate to a vertical state; the tin bar conveying device 3 continues to translate the clamped vertical tin bar to the tin bar delivery port 101, descends at the set speed, and the tin bar gradually melts in the tin cylinder; when the conveying robot 303 reaches the set lowest point, the conveying robot 303 is released, and the remaining part of the tin bar falls into the tin cylinder, and the conveying lifting mechanism 302 and the Y-axis drive mechanism 301 drive the conveying robot 303 to reset to the initial state. When the tin surface sensing sensor senses that the tin surface reaches the set height, the tin addition stops, otherwise the above actions will be repeated to add tin bars.

[0042] The above is a preferred implementation mode of the present invention, but the implementation mode of the present invention is not limited by the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
