Description

Technical Field

[0001] The utility model relates to the technical field of ignition electrodes, and particularly relates to a welding device for electrode needles and wires. Background Art

[0002] The ignition electrode of a gas stove is a device used to ignite fuel. When a high voltage is applied to the ignition electrode, a high voltage arc will be generated in the electrode gap, breaking down the surrounding air to produce a spark, which can spread to the fuel and air to achieve fuel combustion.

[0003] The traditional processing method for electrode needles and wires in ignition electrodes is pure manual eye-protecting welding. The specific method is to first insert the needle into the sand tray. The welder holds the wire vertically with the left hand and aligns it with the end face of the needle, and holds the flame gun with the right hand and aligns it for welding. The disadvantages of this manual welding method include:

[0004] (1) Low efficiency. It is difficult for manual labor to perform welding work for a long time and with high efficiency;

[0005] (2) Poor quality. Welding mainly relies on the senses and experience of the welder. Sometimes under-welding or over-welding may occur, resulting in poor welding, which may lead to problems such as low welding strength, detachment, and oxidation of the solder joints.

[0032] In the present application, unless otherwise clearly specified and limited, the terms in the present application should be understood in a broad sense. For example, connection can be a fixed connection, a detachable connection or an integral connection, can be directly connected, or can be indirectly connected through an intermediate medium; if it involves the electrical field, it can also be an electrical connection or a communication signal connection, etc. For those of ordinary skill in the art, the specific meanings of different terms in the present invention can be understood according to specific circumstances, and the scope of the specific meanings should be limited to realizing the functions of the present application.

[0033] Such as Figure 1 、2 As shown in the figure, a welding device for an electrode needle and a wire includes a frame and a welding unit 1, a clamping unit 2, and a material transfer unit 3 mounted on the frame. The clamping unit 2 includes: a first lifting mechanism 101, and the first lifting mechanism 101 has a connection end for connecting a welding torch 4. The welding unit 1 includes: a first clamping mechanism A201, a first clamping mechanism B202, a shielding member 203, a first displacement mechanism A204, and a first displacement mechanism B205. The first clamping mechanism A201 has a first clamping end A for clamping the needle 5 to be welded, and the first clamping mechanism B202 has a first clamping end B for clamping the wire 6 to be welded. The shielding member 203 is disposed between the first clamping end A and the first clamping end B, and the shielding member 203 is used to determine the distance between the needle 5 and the wire 6. The first displacement mechanism A204 is connected to the shielding member 203 and is used to move the shielding member 203 into or away from between the first clamping end A and the first clamping end B. The first displacement mechanism B205 is connected to the first clamping mechanism A201 or the first clamping mechanism B202 and is used to change the distance between the first clamping mechanism A201 and the first clamping mechanism B202. The material transfer unit 3 has a material transfer end for removing the welded finished product from the clamping unit 2.

[0034] In some embodiments of the present application, as Figure 1 shown (partial schematic diagram of the frame structure), the frame is a frame structure and has a workbench. A bracket 7 is installed above the workbench, and the first lifting mechanism 101 is installed on the bracket 7. The first lifting mechanism 101 includes: a driving member, a sliding plate, a first clamping block, and a second clamping block. The driving member uses a hydraulic cylinder or a pneumatic cylinder and is installed on the bracket 7. The piston rod of the driving member is connected to the sliding plate, and the sliding plate is slidably connected to the bracket 7 in the vertical direction through a guide rail-slider structure. The first clamping block is installed on the front surface of the sliding plate, and the second clamping block is installed on the front side of the first clamping block. The first clamping block and the second clamping block are provided with grooves with matching outer shapes corresponding to the welding torch 4. The welding torch 4 is connected to the sliding plate by clamping the first clamping block and the second clamping block, so that the driving member drives the welding torch 4 to move up and down. When the lower gun head part of the welding torch 4 moves to the welding position of the needle 5 and the wire 6, the welding torch 4 works, and then moves to the upper position after welding to prevent the welding torch 4 from interfering with the movement path of the finished product.

[0035] In some embodiments of the present application, as Figure 3 、 4As shown, the first clamping end A includes a first left jaw A206 and a first right jaw A207 that can perform clamping actions. Both the first left jaw A206 and the first right jaw A207 are provided with V-shaped grooves that face each other and are used for clamping the needle 5. The first clamping end B includes a first left jaw B208 and a first right jaw B209 that can perform clamping actions. Both the first left jaw B208 and the first right jaw B209 are provided with V-shaped grooves that face each other and are used for clamping the thread 6. The self-centering effect of the V-shaped groove is good, which is convenient for centering the needle 5 and the thread 6, and is also convenient for clamping needles 5 and threads 6 with different diameters. By changing the distance between the first left jaw A206 and the first right jaw A207, the clamping or releasing action of the first clamping mechanism A201 is realized. By changing the distance between the first left jaw B208 and the first right jaw B209, the clamping or releasing action of the first clamping mechanism B202 is realized.

[0036] In some embodiments of the present application, as Figure 3 shown, both the first clamping mechanism A201 and the first clamping mechanism B202 adopt finger cylinders. The first left jaw A206, the first right jaw A207, the first left jaw B208, and the first right jaw B209 are all provided with waist-shaped holes, and bolts are inserted into the waist-shaped holes and are threadedly connected to the two movable fingers of the finger cylinder to form a position-adjustable connection structure, so that the relative positions of the first left jaw A206 and the first right jaw A207 can be adjusted and installed on the same finger cylinder, and the relative positions of the first left jaw B208 and the first right jaw B209 can be adjusted and installed on the same finger cylinder, which is convenient for adjusting the clamped needle 5 and thread 6 to the concentric position.

[0037] In some embodiments of the present application, as Figure 3 shown, the shielding member 203 is a baffle. The first displacement mechanism A204 adopts a cylinder. The cylinder is installed under the workbench, and the piston rod of the cylinder is connected to one side of the shielding member 203. The shielding member 203 is driven to move by the cylinder. The shielding member 203 has a first position and a second position. The first position is located between the first clamping end A and the first clamping end B, and the second position is located outside the area between the first clamping end A and the first clamping end B. When the baffle is in the first position, the needle 5 and the thread 6 are manually placed so that the needle 5 and the thread 6 are respectively in contact with the two side surfaces of the shielding member 203. The end portions of the needle 5 and the thread 6 to be welded are respectively positioned by the shielding member 203, and then the shielding member 203 is moved away, and the needle 5 and the thread 6 are driven to contact and form a mutually pushing state. Therefore, setting the baffle is convenient for ensuring that the needle 5 and the thread 6 have the same spacing during feeding, thereby ensuring the consistency and reliability of the welding quality.

[0038] In some embodiments of the present application, two guiding blocks are configured at the lower end of the workbench. A guiding gap is formed between the guiding blocks, and a partial structure of the shielding member 203 is slidably inserted into the guiding gap, thereby improving the movement stability and positioning stability of the shielding member 203 through the guiding gap.

[0039] In some embodiments of the present application, such as Figure 1 shown, taking the first clamping mechanism B202 being installed on the first displacement mechanism B205 as an example (the first clamping mechanism A201 being installed on the first displacement mechanism B205 can be implemented with the same structure), the first displacement mechanism B205 includes: a cylinder, a guide rail, a slider, and a slide plate. The finger cylinder of the first clamping mechanism B202 is installed on the slide plate. A slider is installed at the lower end of the slide plate, and the slider is slidably disposed on the guide rail connected to the frame. The cylinder is installed on the frame, and the cylinder is connected to the slide plate. The cylinder is used to drive the slide plate to move, thereby changing the distance between the first clamping mechanism B202 and the first clamping mechanism A201. When the first clamping mechanism B202 and the first clamping mechanism A201 approach, the needle 5 and the thread 6 are in a squeezing state, increasing the welding reliability and avoiding the phenomenon of virtual connection forming a virtual weld.

[0040] In some embodiments of the present application, such as Figure 1 shown, the material transfer unit 3 includes: a second displacement mechanism A301, a second displacement mechanism B302, and a second clamping mechanism 303. Both the second displacement mechanism A301 and the second displacement mechanism B302 use cylinders, such as double-axis cylinders, and the second clamping mechanism 303 uses a pneumatic gripper. The second displacement mechanism A301 is installed horizontally on the bracket 7. A connecting plate is installed at the end of the piston rod of the second displacement mechanism A301, and the second displacement mechanism B302 arranged vertically is installed on the connecting plate. The piston rod of the second displacement mechanism B302 is installed with the second clamping mechanism 303 arranged vertically. The second clamping mechanism 303 is located obliquely above the side of the first clamping mechanism B202 facing away from the first clamping mechanism A201. The second displacement mechanism A301 is used to control the front and back positions of the second clamping mechanism 303. When the material transfer unit 3 is in the initial state, the clamping unit 2 is located obliquely in front of the material transfer unit 3. The second displacement mechanism B302 is used to control the height position of the second clamping mechanism 303. When the second displacement mechanism B302 does not act, the second clamping mechanism 303 is located obliquely above the clamping unit 2, and the second clamping mechanism 303 is used to clamp the finished product after welding. Through the cooperation of the second displacement mechanism A301 and the second displacement mechanism B302, the second clamping mechanism 303 can be displaced in two degrees of freedom, so as to remove the finished product from the clamping unit 2.

[0041] In some embodiments of the present application, such as Figure 1As shown in the figure, the welding device further includes: an aggregate member 8, which is placed on the workbench and is arranged behind the clamping unit 2. The aggregate member 8 is used to collect the finished products after welding. The aggregate member 8 is in the form of a tray structure or a frame structure, which facilitates the collection of the finished products through the aggregate member 8.

[0042] When the welding device for the electrode needle and wire works, an operator holds the needle 5 in one hand and the wire 6 in the other hand, and places them in the corresponding first clamping mechanisms A201 and B202 respectively. The first left clamping jaw A206 and the first right clamping jaw A207 clamp the needle 5, and the first left clamping jaw B208 and the first right clamping jaw B209 clamp the wire 6. The shielding member 203 displaces and moves away from between the needle 5 and the wire 6. The first clamping mechanism B202 moves towards the first clamping mechanism A201, so that the needle 5 and the wire 6 are in a mutually extruded state. The welding torch 4 moves down to the set position and welds the extruded part of the needle 5 and the wire 6. After welding, the welding torch 4 moves up. The second clamping mechanism 303 moves forward and then moves down. The second clamping mechanism 303 clamps the finished product after welding. The second clamping mechanism 303 moves up and then moves backward. After the second displacement mechanism A301 resets, the second displacement mechanism B302 moves down. The second clamping mechanism 303 releases the finished product, and the finished product falls into the aggregate member 8 below. The second displacement mechanism B302 moves up and resets, thus completing a welding operation of the electrode needle 5 and the wire 6.

[0043] The above are only the embodiments of the present invention. Common knowledge such as the specific structures and characteristics in the solutions is not described in detail here. Those of ordinary skill in the art know all the common technical knowledge in the technical field to which the utility model belongs before the application date or the priority date, can know all the existing technologies in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application and combined with their own abilities, improve and implement this solution. Some typical well-known structures or well-known methods should not become obstacles for those of ordinary skill in the art to implement this application. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
