Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt welding, in particular to a fusion welding machine. Background Art

[0002] PFA plastic pipes are often used to protect the surface of wafer electroplating lines. PFA plastic has excellent chemical corrosion resistance and good electrical properties. Its electrical insulation is not affected by temperature. Pipes need to be welded during the production process of wafer electroplating lines.

[0003] In a traditional hot melt welding machine, the milling cutter disk is manually operated to complete the milling of the pipe end face, and then the heating plate is replaced to complete the heating of the pipe end face, and then the two pipes are butt-jointed to achieve the final welding. When the above process is manually operated, the heating time of the pipe end face is not easy to control, and the efficiency of manually withdrawing the heating plate is too low. Utility Model Content

[0004] The problem solved by the utility model is that the heating time of the pipe end surface is inconvenient to control and the efficiency of manually withdrawing the heating plate is too low.

[0005] To solve the above problems, the utility model provides a fusion welding machine, which includes: a clamping assembly, the clamping assembly includes a first clamping piece and a second clamping piece, and a fusion area is provided between the first clamping piece and the second clamping piece; a rotating assembly, the rotating assembly is arranged on one side of the clamping assembly, and the rotating assembly includes: a rotating shaft and a locking assembly; the locking assembly is arranged on either side of the rotating shaft, the locking assembly includes a locking piece and a signal switch, the locking piece is connected to the rotating shaft, the signal switch is located on one side of the rotating shaft, and the signal switch can receive a signal to achieve its cooperation and disconnection with the locking piece; a heating assembly, the heating assembly is arranged on the rotating shaft, and the heating assembly can be rotated to the fusion area through the rotating shaft; and when the locking piece and the signal switch cooperate, the heating assembly is located in the fusion area.

[0006] The technical effect achieved after adopting this technical solution is as follows: the first clamping member and the second clamping member are used to clamp two pipes to be welded respectively. After the two pipes are fixed and extended into the welding area, they can be hot-melted and butt-jointed; the rotating assembly is used to control the rotation of the heating assembly, so that the heating assembly enters the welding area for welding or quickly exits the welding area after welding is completed; when the locking piece and the signal switch cooperate, it indicates that the rotating shaft is rotated into place at this time, and the heating assembly can accurately perform welding. When the welding reaches the preset time or other conditions indicating that the welding is completed, the signal switch receives a signal and automatically disconnects it from the locking piece, so that the heating assembly is separated from the welding area, thereby facilitating the control of the heating time and improving efficiency.

[0007] Furthermore, the first clamping member is provided with a first clamping hole, the second clamping member is provided with a second clamping hole, and the first clamping hole corresponds to the second clamping hole; the fusion welding machine also includes: a baffle, the baffle is located on one side of the clamping assembly, and the baffle can be moved to the fusion area, and the baffle can be blocked between the first clamping hole and the second clamping hole.

[0008] The technical effect achieved after adopting this technical solution is as follows: the first clamping hole can be used to clamp one of the pipes, the second clamping hole can be used to clamp the other pipe, and the baffle is used to position the two pipes, so that the positions of the two pipes extending into the welding area and the distance between the two meet the preset requirements, making it convenient for the heating component to heat and weld the two pipes.

[0009] Furthermore, the fusion welding machine further comprises: a side bracket, the side bracket being arranged on one side of the first clamping member or on one side of the second clamping member; and the baffle being rotatably connected to the side bracket.

[0010] The technical effect achieved after adopting this technical solution is as follows: the side bracket is used to install the baffle, and the side bracket is connected to the first clamping member or the second clamping member, so as to ensure that the relative position accuracy of the baffle and the first clamping hole and the second clamping hole meets the tolerance requirements, so that the position of the baffle is more accurate when it is rotated between the first clamping hole and the second clamping hole.

[0011] Furthermore, the fusion welding machine also includes: a reset detector, which is arranged on one side of the clamping assembly; the baffle has an initial state, in which the baffle is located outside the fusion area and the reset detector faces the baffle.

[0012] The technical effect achieved after adopting this technical solution is as follows: the reset detector is used to detect whether the baffle returns to the initial state. For example, when the initial state is a vertical state, the reset detector rotates toward the baffle to the position when it is in the vertical state, thereby ensuring that the baffle is successfully reset.

[0013] Furthermore, the heating assembly includes: a mounting piece and a heating plate, wherein the mounting piece is fixed to the rotating shaft, and one end of the mounting piece away from the rotating shaft is connected to the heating plate; when the locking piece and the signal switch are matched, the heating plate is located in the welding area; when the locking piece and the signal switch are disconnected, the heating plate swings downward and disengages from the welding area.

[0014] The technical effect achieved after adopting this technical solution is as follows: the heating plate can rotate with the rotating shaft through the mounting part, and the signal switch locks the position of the locking plate to ensure that the heating plate can move into place when welding is required; after the locking plate and the signal switch are unlocked, the heating plate can swing downward around the rotating shaft with the help of the pre-tightening force of the rotating shaft or the gravity of the heating assembly, thereby automatically resetting.

[0015] Furthermore, the heating plate includes at least one bending portion, and the bending portion is provided with a notch.

[0016] The technical effect achieved after adopting this technical solution is: the heating plate can improve the uniformity of heating after being bent; the notch avoids tip discharge at the bent part and also avoids stress caused by high temperature, which causes the right-angle mouth to be easily broken or deformed.

[0017] Furthermore, the clamping assembly also includes: a driving device and a guiding device, the driving device is arranged on the side of the second clamping member away from the first clamping member, and the guiding device is arranged on both sides of the second clamping member; the driving device is used to control the second clamping member to approach or move away from the first clamping member, and the guiding device is used to guide the second clamping member to approach or move away from the first clamping member.

[0018] The technical effect achieved after adopting this technical solution is as follows: the driving device is used to push or pull the second clamping member so that the pipeline clamped by the second clamping member can be docked with the pipeline clamped by the first clamping member; the guiding device is used to guide the second guide member to slide to avoid the second guide member from being offset, thereby ensuring that the central axes of the first clamping hole and the second clamping hole can coincide, and the corresponding two pipelines can be accurately welded.

[0019] Furthermore, a locking groove is provided on the circumferential side of the rotating shaft; the rotating assembly also includes: a locking block, which is overlapped on the rotating shaft, and when the locking groove rotates with the rotating shaft to a position corresponding to the locking block, the locking block cooperates with the locking groove due to gravity.

[0020] The technical effect achieved after adopting this technical solution is that the locking block can automatically fall down and lock with the locking groove, further preventing the shaft from rotating in the opposite direction, so that the heating component can heat stably.

[0021] Furthermore, the fusion welding machine includes: a cam and an abutment portion, the abutment portion is fixed to one side of the rotating shaft; the cam is arranged on the rotating shaft and rotates with the rotating shaft; the cam has at least one protrusion, and the distance between the protrusion and the axis of the rotating shaft is greater than or equal to the distance between the abutment portion and the axis of the rotating shaft.

[0022] The technical effect achieved by adopting this technical solution is that the protrusion of the cam can generate damping when it contacts the abutment, thereby avoiding excessive movement at necessary positions. For example, when the locking plate and the signal switch are matched, there is a protrusion in contact with the abutment, which prevents the locking plate from moving too fast relative to the signal switch and causing it to pass over the signal switch; or, after the heating component automatically leaves the welding area, there is another protrusion in contact with the abutment, which prevents the heating plate from moving too fast and causing it to collide with the outer shell of the rotating component.

[0023] Furthermore, the fusion welding machine further includes: an operating rod, the operating rod is connected to one side of the rotating shaft, and the operating rod is perpendicular to the axis of the rotating shaft.

[0024] The technical effect achieved after adopting this technical solution is: the operating lever is convenient for manually controlling the rotation of the shaft, so as to rotate the heating component to the welding area and make the locking piece and the signal switch cooperate.

[0025] In summary, the above-mentioned technical solutions of the present application may have one or more of the following advantages or beneficial effects: i) when the locking plate and the signal switch cooperate, it indicates that the rotating shaft is rotated into place at this time, and the heating component can be accurately welded. When the welding reaches the preset time or other conditions indicating that the welding is completed, the signal switch obtains a signal and automatically disconnects it from the locking plate, so that the heating component is separated from the welding area, thereby facilitating the control of the heating time and improving the efficiency; ii) the heating plate can be bent to improve the uniformity of heating; the notch avoids tip discharge at the bent portion and also avoids stress caused by high temperature, which makes the right-angle mouth easy to break or deform; iii) the protrusion of the cam can generate damping when it contacts the abutment portion, thereby avoiding excessive movement at the necessary position.
