[0002] In gas appliances such as gas stoves, gas water heaters, and some industrial combustion equipment, the ignition needle plays a vital role. It not only enables initial ignition, but also re-ignites the fuel when needed to ensure the normal operation of the equipment.

[0003] The main working parts of an ignition needle generally consist of a conductive core rod, an insulating sleeve, and an end electrode. During production, the conductive core rod must first be welded to a connecting piece (a stamped part) that connects the ignition needle to the gas equipment.

Before welding, the core rod must be inserted into the corresponding through-hole in the connector, and then the welding process can begin. Operator proficiency, concentration, and fatigue all affect welding quality, and prolonged welding work can also reduce welding efficiency. Utility Model Content

The beneficial effect of this step is that the limiting block can realize the function of quickly positioning the first slider, thereby improving welding efficiency.

[0016] In one embodiment of the present application, the vertical motion mechanism includes a base; a second guide rail vertically connected to the base, a second slider slidably disposed on the second guide rail; and a driver connected to the second slider for driving the second slider.

The vertical movement mechanism 3 has a second slider 301 that moves vertically, and the mounting bracket 4 is connected to the second slider 301. The mounting bracket 4 is used to connect the welding gun 5.

[0035] Specifically, such as Figure 1 、 2 As shown, the ignition needle welding tool also includes: a base plate, and the horizontal movement mechanism 1 and the vertical movement mechanism 3 are both installed on the base plate.

[0036] Specifically, such as Figure 3 As shown, the transverse motion mechanism 1 further includes a first guide rail 102 and a stopper 103. The first guide rail 102 is arranged transversely, and the first slider 2 is slidably arranged on the upper end of the first guide rail 102. The stopper 103 is located at the end of the first guide rail 102 and is used to position the first slider 2 in the welding position. The stopper 103 can realize the function of quickly positioning the first slider 2, thereby improving welding efficiency.

[0037] Specifically, such as Figure 3 As shown, the first guide rail 102 and the limit block 103 are connected to the base plate by bolts. The first guide rail 102 is set in a direction parallel to the horizontal plane. The limit block 103 is located at the end of the first guide rail 102 facing the vertical motion mechanism 3. The limit block 103 is used to block the position of the first slider 2, thereby positioning the first slider 2 in the welding position.

[0038] Specifically, such as Figure 2 、 4As shown, the vertical motion mechanism 3 includes a base 302, a second guide rail 303, and a driving member 304. The second guide rail 303 is vertically connected to the base 302, the second slider 301 is slidably disposed on the second guide rail 303, and the driving member 304 is connected to the second slider 301 to drive the second slider 301. The driving member 304 realizes the function of mechanically driving the movement of the welding gun 5, thereby reducing the intensity of manual work.

[0039] Specifically, the base 302 includes a horizontal plate and a vertical plate. The vertical plate is vertically arranged in the middle position of the upper end surface of the horizontal plate. The driving member 304 adopts a double-rod cylinder. The driving member 304 is connected to one side of the vertical plate by bolts. The block at the end of the guide rod of the driving member 304 is installed with an L-shaped connecting rod. The horizontal edge of the connecting rod is bolted to the block, and the vertical edge of the connecting rod is bolted to the side of the second slider 301.

[0040] Specifically, such as Figure 2 As shown, the vertical motion mechanism 3 further includes an XY-axis displacement platform 305 mounted on the upper end of the base plate. The base 302 is mounted on the upper end of the XY-axis displacement platform 305 and is used to adjust the horizontal position of the base 302. The XY-axis displacement platform 305 allows for fine adjustment of the position of the base 302, thereby improving the accuracy of the welding position of the welding gun 5.

[0041] Specifically, such as Figure 4 As shown, the vertical motion mechanism 3 further includes an X-axis displacement platform 306, which is connected to the end surface of the second slider 301 facing the horizontal motion mechanism 1. The mounting bracket 4 is mounted on the X-axis displacement platform 306 and is used to adjust the height position of the mounting bracket 4. The X-axis displacement platform 306 allows for fine adjustment of the height position of the welding gun 5, thereby improving the accuracy of the welding position of the welding gun 5.

[0042] Specifically, the XY-axis displacement platform 305 and the X-axis displacement platform 306 are both purchased parts.

[0043] Specifically, such as Figure 4 As shown, the lower end of the mounting bracket 4 is connected to the X-axis moving platform by bolts, and the upper end of the mounting bracket 4 is a clamping block, which includes a front block 307 and a rear block 308. The rear block 308 is bolted to the vertical structure of the mounting bracket 4, and the front block 307 is connected to the front end of the rear block 308 by bolts. The rear end of the front block 307 and the front end of the rear block 308 are both provided with semi-arc grooves corresponding to the welding gun 5. When the front block 307 is bolted to the rear block 308, the two grooves are combined to form a clamping groove for clamping the welding gun 5. The lower end of the gun body of the welding gun 5 is inserted into the clamping groove, and the gun body is clamped by the clamping groove to position the welding gun 5.

[0044] When this type of ignition needle welding tool is in operation, the operator inserts the conductive core rod into the positioning hole 202, then places the connecting piece on the positioning surface 201 and inserts the welding end of the conductive core rod into the corresponding through hole of the connecting piece, pushes the first slider 2 until it is positioned and contacted with the limit block 103, starts the driving member 304, and the driving member 304 pushes the second slider 301 downward, the welding gun 5 is driven to move to the welding position and then stops moving, starts the welding gun 5, and the welding gun 5 welds the end of the conductive core rod to the connecting piece, then starts the driving member 304, and the driving member 304 drives the welding gun 5 upward, so that the welding gun 5 is out of the welding position, pulls the first slider 2, so that the welded product moves out from under the welding gun 5, and then removes the welded product, thereby completing a welding job.

[0045] Example 2

[0046] Based on the first embodiment, the ignition needle welding tool further includes a position sensor connected to the base 302. The position sensor is used to sense the height of the second slider 301, thereby controlling the movement of the driving member 304. The position sensor can accurately position the welding gun 5 at the welding height, thereby improving welding quality.

[0047] Specifically, the position sensor uses a micro switch, which is installed on the side of the horizontal plate of the base 302. The micro switch is located directly below the horizontal edge of the connecting rod. The micro switch is electrically connected to the control device of the double-rod cylinder. When the horizontal edge contacts the micro switch, the micro switch sends a control signal, and the control device controls the cylinder to stop moving, thereby positioning the welding gun 5 in the welding position.

[0048] Example 3

[0049] On the basis of the first or second embodiment, the ignition needle welding tool further includes: a controller connected to the welding gun 5 , and the controller is used to control the welding time of the welding gun 5 .

[0050] Specifically, the controller is provided with a counter and a time relay, and the time relay is connected to the electrical signal of the control device of the welding gun 5. The time relay is preset with the working time of the welding gun 5 for one welding. When the welding gun 5 starts welding, the time relay starts working until the welding time is completed. The time relay disconnects the working circuit of the welding gun 5, causing the welding gun 5 to stop welding. By configuring the time relay, the single working time of the welding gun 5 can be automatically controlled, thereby ensuring the consistency of the welding quality.
