[0045] Example 1

[0046] See also Figures 1 to 6 As shown, the tungsten electrode replacement device provided by the present application is used for welding equipment, and the tungsten electrode replacement device includes a loosening and clamping mechanism 101 and a replacement mechanism 102. Before the old tungsten electrode 104 is replaced, the loosening and clamping mechanism 101 needs to disconnect the connection between the tungsten electrode clamp 105 and the old tungsten electrode 104. The replacement mechanism 102 removes the old tungsten electrode 104 and replaces it with a new tungsten electrode 104. Subsequently, the loosening and clamping mechanism 101 is released to connect the tungsten electrode clamp 105 to the new tungsten electrode 104. The tungsten electrode clamp 105 is used to clamp the tungsten electrode 104 and conduct the welding current.

[0047] Specifically, the loosening and clamping mechanism 101 is installed at the welding head 103 of the welding equipment. The loosening and clamping mechanism 101 includes a fixing member 107 and a tungsten electrode clamp driving assembly 106. The fixing member 107 is used to position the tungsten electrode 104 of the welding head 103. The tungsten electrode clamp driving assembly 106 is used to drive the tungsten electrode clamp 105 of the welding head 103 toward or away from the tungsten electrode 104 to connect the tungsten electrode clamp 105 to a new tungsten electrode 104 or to disconnect the tungsten electrode clamp 105 from the old tungsten electrode 104. When the tungsten electrode clamp driving assembly 106 drives the tungsten electrode clamp 105 to connect or disconnect with the tungsten electrode 104, the fixing member 107 is used to fix the tungsten electrode 104 to ensure that the position of the tungsten electrode 104 remains unchanged, so that the tungsten electrode clamp 105 and the tungsten electrode 104 can be reliably connected and disconnected.

[0048] The replacement mechanism 102 is positioned opposite the loosening and clamping mechanism 101 and includes a loading assembly 108 and a unloading assembly 109 to replace the tungsten electrode 104 mounted on the fixture 107. The replacement process is as follows: When the tungsten electrode clamp 105 is disengaged from the old tungsten electrode 104, the unloading assembly 109 is used to remove the old tungsten electrode 104 from the fixture 107 to recycle it. The loading assembly 108 then delivers the new tungsten electrode 104 to the fixture 107. At this point, the tungsten electrode clamp drive assembly 106 connects the tungsten electrode clamp 105 to the new tungsten electrode 104 on the fixture 107. These two steps complete the replacement of the tungsten electrode 104.

[0049] The tungsten electrode replacement device provided in the present application, by setting a loosening clamping mechanism 101 and a replacement mechanism 102, first disconnects the tungsten electrode clamp 105 and the old tungsten electrode 104, then replaces the old tungsten electrode 104, and then connects the new tungsten electrode 104 and the tungsten electrode clamp 105, completing all the actions of replacing the tungsten electrode 104. There is no need to use manual operation to replace the tungsten electrode 104, so that the welding process can be fully automated and unmanned.

[0050] Furthermore, when the tungsten electrode 104 of the welding head 103 needs to be replaced, the welding process can be paused, and the walking mechanism (not shown) can be used to drive the replacement mechanism 102 to move to the welding head 103 to replace the tungsten electrode 104.

[0051] The following describes the functions of each part in the order of the welding equipment's workflow:

[0052] 1. Loosening the Clamping Mechanism 101

[0053] See also Figure 2 and Figure 3 As shown ( Figure 3Part of the structure is hidden to show the internal tungsten electrode clamp 105). In an optional solution of this embodiment, the loosening and clamping mechanism 101 further includes a support frame 110 for fixing the tungsten electrode clamp drive assembly 106. The support frame 110 is connected to the welding head 103. Specifically, the housing of the welding head 103 is connected to the main body 111 of the welding device via a bracket. The support frame 110 is connected to the housing of the welding head 103. The support frame 110 is formed with a protrusion for connecting to the bracket. The above structure enables a compact connection between the welding head 103, the support frame 110, and the bracket.

[0054] The tungsten electrode clamp drive assembly 106 includes a driving device 112 and a pusher 113. The driving device 112 can be specifically a cylinder and is mounted on the support frame 110. The driving end of the driving device 112 is connected to one end of the pusher 113. The other end of the pusher 113 extends from the rear end of the housing of the welding head 103 into the housing and is connected to the rear end of the tungsten electrode clamp 105. The head end of the tungsten electrode clamp 105 faces the tungsten electrode 104. The tungsten electrode clamp 105 is cylindrical and has multiple notches circumferentially formed at the head end of the tungsten electrode clamp 105. When the head end of the tungsten electrode clamp 105 is connected to the tungsten electrode 104, the provision of the notches can appropriately increase the diameter of the head end of the tungsten electrode clamp 105, so that the tungsten electrode clamp 105 can be placed around the tungsten electrode 104. When the tungsten electrode 104 extends into the middle and rear section of the tungsten electrode clamp 105 , the diameter of the tungsten electrode clamp 105 remains unchanged, thereby ensuring reliable connection with the tungsten electrode 104 .

[0055] A fixing member 107 for fixing the tungsten electrode 104 is installed at the head end of the housing. The fixing member 107 is formed with a positioning hole, which is concentric with the sleeve hole of the tungsten electrode clamp 105 and the porcelain nozzle of the welding head 103 ( Figure 2 and Figure 3 When the replacement mechanism 102 inserts the tungsten electrode 104 into the positioning hole, the positioning hole ensures accurate positioning of the tungsten electrode 104, facilitating the tungsten electrode clamp 105 to be placed around the tungsten electrode 104. The replaced tungsten electrode 104 remains in the same position as before, ensuring accurate welding position.

[0056] In an optional solution of this embodiment, the pushing member 113 includes a push rod 114 and a connecting plate 115; one end of the connecting plate 115 is connected to the pushing drive device 112, and the other end of the connecting plate 115 is connected to one end of the push rod 114, and the other end of the push rod 114 is connected to the tungsten electrode clamp 105; the support frame 110 is formed with a guide hole 116, and the connecting plate 115 passes through the guide hole 116 to guide the movement of the push rod 114.

[0057] In this embodiment, due to the large size of the tungsten electrode clamp drive assembly 106, it cannot be directly installed at the rear end of the welding head 103 housing. In the solution of the present application, a support frame 110 is used to space the cylinder and the bracket. The driving end of the cylinder is connected to the push rod 114 via a vertical connecting plate 115. The push rod 114 extends from the rear end of the welding head 103 housing into the housing to realize the driving of the tungsten electrode clamp 105.

[0058] Furthermore, in order to ensure the accuracy of the movement direction of the push rod 114, a guide hole 116 is opened on the support frame 110, which is consistent with the length direction and the movement direction of the push rod 114. The cylinder drives the connecting plate 115 to move in the guide hole 116 to guide the movement of the push rod 114 and ensure that the tungsten electrode clamp 105 and the tungsten electrode 104 are accurately aligned.

[0059] Example 2

[0060] The tungsten electrode replacement device in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0061] 2. Position adjustment component 117

[0062] Before replacing the tungsten electrode 104 on the fixture 107, the position of the loading assembly 109 and the unloading assembly 108 relative to the fixture 107 must be adjusted using the position adjustment assembly 117. In an optional solution of this embodiment, the replacement mechanism 102 further includes the position adjustment assembly 117; the loading assembly 108 includes a conveying portion for conveying the tungsten electrode 104 toward the fixture 107; and the unloading assembly 109 includes a clamping portion for removing the tungsten electrode 104 from the fixture 107. The position adjustment assembly 117 is connected to the loading assembly 108 and the unloading assembly 109 and is used to adjust the positions of the loading assembly 108 and the unloading assembly 109 so that the conveying portion and the clamping portion respectively move to the fixture 107. When the position adjustment component 117 drives the loading component 108 to be opposite to the fixing part 107, the loading component 108 can transport the tungsten electrode 104 to the fixing part 107. When the position adjustment component 117 drives the unloading component 109 to be opposite to the fixing part 107, the unloading component 109 can remove the tungsten electrode 104 on the fixing part 107.

[0063] Specifically, position adjustment assembly 117 includes a base 118, a mounting frame 119, and a lifting member. Both loading assembly 108 and unloading assembly 109 are mounted on mounting frame 119, with the conveying portion and the clamping portion spaced apart in height. Base 118 is located at the bottom of mounting frame 119, with one side of base 118 hinged to one side of mounting frame 119. A lifting member is disposed between base 118 and mounting frame 119, driving the other side of mounting frame 119 to raise or lower, thereby adjusting the position of the conveying portion and the clamping portion relative to fixed member 107.

[0064] In this embodiment, the mounting frame 119 on which the loading assembly 108 and the unloading assembly 109 are mounted is hingedly connected to the base 118, thereby adjusting the position of the conveying portion of the loading assembly 108 and the clamping portion of the unloading assembly 109 relative to the fixed member 107. Specifically, a lifting component is installed at the bottom of the base plate, and the lifting component includes a servo motor, a synchronous pulley group 120, a screw module 121, and a lifting pusher 122. The servo motor drives the screw of the screw module 121 to rotate through the synchronous pulley group 120. The nut of the screw module 121 is connected to the lifting pusher 122, so that the lifting component moves in the height direction to push the mounting frame 119 to be hinged relative to the base 118, thereby adjusting the position of the conveying portion of the loading assembly 108 and the clamping portion of the unloading assembly 109.

[0065] 3. Replacement mechanism 102

[0066] See also Figure 4 and Figure 5 As shown, in an optional solution of this embodiment, the loading assembly 108 includes an inflation device 123 and a conveying pipe 124; the tungsten electrode 104 is placed in the conveying pipe 124, and the inflation device 123 is arranged at one end of the conveying pipe 124 away from the loosening and clamping mechanism 101, and the inflation device 123 is used to blow air into the conveying pipe 124 to blow the tungsten electrode 104 in the conveying pipe 124 toward the fixing member 107.

[0067] In this embodiment, due to the relatively thin size of the tungsten electrode 104, when loading the tungsten electrode 104, to facilitate insertion of the insertion end of the tungsten electrode 104 into the positioning hole of the fixing member 107, the tungsten electrode 104 is placed in the delivery tube 124 and the airflow drives the tungsten electrode 104 to move. This allows precise loading positioning by simply aligning the mouth of the delivery tube 124 with the positioning hole. Furthermore, the airflow-driven movement of the tungsten electrode 104 is less likely to damage it. Specifically, an airflow channel is formed within the delivery tube 124, adapted to the size of the tungsten electrode 104. The outlet of the airflow channel is aligned with the positioning hole of the fixing member 107, and the thrust generated by the airflow can push the tungsten electrode 104 into the positioning hole of the fixing member 107.

[0068] In an optional solution of this embodiment, the loading assembly 108 further includes a switching component; the switching component includes a switching drum 125 and a switching drive assembly, the number of the delivery tubes 124 is multiple, and the multiple delivery tubes 124 are arranged at intervals on the side wall of the switching drum 125, and end plates 126 are provided at both ends of the switching drum 125, and the pipe openings at both ends of the delivery tube 124 are respectively installed on the two end plates 126; the switching drive assembly is used to drive the switching drum 125 to rotate, so that the pipe opening on the air intake side of any delivery tube 124 moves to the inflation device 123, and the pipe opening on the loading side moves to the fixing member 107. Specifically, the switching drive assembly includes a servo motor, a reducer, a driving gear and a driven gear 127. The servo motor and the reducer are connected, and the reducer drives the driving gear to rotate. The driven gear 127 is installed on the switching drum 125, and the driving gear and the driven gear 127 are engaged to drive the switching drum 125 to rotate.

[0069] After the tungsten electrode 104 in the delivery tube 124 is blown toward the fixing member 107, if the tungsten electrode 104 needs to be replaced again, a new tungsten electrode 104 needs to be added to the delivery tube 124. Since the tungsten electrode 104 needs to be replaced multiple times during the welding process, in order to reduce the frequency of adding tungsten electrodes 104 to the delivery tube 124, in this embodiment, multiple delivery tubes 124 are provided, and the multiple delivery tubes 124 are arranged on the switching drum 125. Specifically, see Figure 4 and Figure 5 As shown, Figure 5 The outer shell surrounding the switching drum 125 is hidden in the figure. One end plate 126 of the switching drum 125 faces the clamping and releasing mechanism. The "12 o'clock" position of this end plate 126 serves as a conveying portion, which is used to face the fixing member 107 to deliver the tungsten electrode 104 to the positioning hole. The inflator 123 is located at the "12 o'clock" position of the other end plate 126 of the switching drum 125. This "12 o'clock" position of this end plate 126 serves as an air inlet. Each delivery tube 124 rotates between the delivery portion and the air inlet to load the tungsten electrode 104 within the tube, eliminating the need for multiple inflators 123 to achieve the conveying function of the tungsten electrode 104.

[0070] In an optional solution of this embodiment, a through hole 128 is formed in the middle of the switching drum 125, the length direction of the through hole 128 is the axial direction of the switching drum 125, and the unloading component 109 is installed in the through hole 128; the loading component 108 and the unloading component 109 are integrated and installed in the switching drum 125 to make the entire device more compact.

[0071] See also Figure 6As shown, the blanking assembly 109 includes an advance and retreat drive member 129, a clamp 130, a conveyor belt 131, and a material receiving box 132. The advance and retreat drive member 129 is used to drive the clamp 130 to extend from the through-hole 128 or retract into the through-hole 128 to clamp the tungsten electrode 104 and release the tungsten electrode 104 onto the conveyor belt 131. In other words, during the blanking process, the clamp 130 extends through the through-hole 128 to hold the tungsten electrode 105 for blanking, and releases the tungsten electrode 104 so that the tungsten electrode 104 falls onto the conveyor belt 131. At other times, the advance and retreat drive member 129 is always hidden in the through-hole 128 to avoid collision with other mechanisms. The material receiving box 132 is located at the end of the conveyor belt 131 away from the clamp 130. The conveyor belt 131 is used to transport the tungsten electrode 104 to the material receiving box 132 to achieve the recovery of the discarded tungsten electrode 104. Preferably, baffles are provided on both sides of the conveyor belt 131 to prevent the tungsten electrode 104 from falling off the conveyor belt 131 during transportation.

[0072] Specifically, the forward and backward driving member 129 is a cylinder, and the clamping jaw 130 is a pneumatic chuck.

[0073] In an optional solution of this embodiment, the blanking assembly 109 further includes a guide member 133; the guide member 133 comprises a slide rail mounted within the through hole 128 and a slider sliding along the rail. The driving end of the forward and backward drive member 129 is connected to the slider, which is in turn connected to the clamping jaw 130. The provision of the guide member 133 ensures the accurate movement path of the clamping jaw 130, thereby achieving reliable gripping of the tungsten electrode 104. A shock absorber 134, specifically a shock absorbing spring, is also provided between the slider and the clamping jaw 130 to prevent the tungsten electrode 104 from falling due to vibration generated by the cylinder driving the clamping jaw 130.
