[0032] See also Figure 1-9 As shown, the present invention relates to a high-voltage discharge tube pin welding machine, comprising a welding machine frame 1, on which a clamping arm mechanism 2, a clamping nozzle mechanism, and a welding pad 4 are provided. A plurality of workstation slots 41 are provided on the periphery of the welding pad 4. The workstation slots 41 are used to place a workpiece 9 to be processed, wherein the workpiece 9 to be processed comprises a tube body 92 and electrode sheets 91 arranged on both sides of the tube body 92. The tube body 92 is placed in the workstation slots 41, and the electrode sheets 91 on both sides protrude from both sides of the workstation slots 41. The clamping arm mechanism 2 comprises a clamping arm bracket 21, a first clamping arm 23, and a second clamping arm 24. The first clamping arm 23 and the second clamping arm 24 are respectively provided on the clamping arm bracket 21. The first clamping arm 23 and the second clamping arm 24 are respectively located on both sides of the welding pad 4. The first clamping arm 23 and the second clamping arm 24 respectively clamp the electrode sheets 91 at both ends of the workpiece 9 to be processed.

[0033] The clamping mechanism includes a first clamping assembly 31 and a second clamping assembly 32, which are arranged on both sides of the welding pad 4. The first clamping assembly 31 and the second clamping assembly 32 are respectively located on both sides of the workpiece 9. The first clamping assembly 31 and the second clamping assembly 32 are respectively clamped on the lead 10, and the first clamping assembly 31 and the second clamping assembly 32 respectively drive the lead 10 to abut against the electrode sheets 91 at both ends of the workpiece 9, and the lead 10 and the electrode sheets 91 at both ends of the workpiece 9 are electrically welded.

[0034] In this embodiment, the first clamping arm 23 and the second clamping arm 24 are symmetrical structures. The first clamping arm 23 and the second clamping arm 24 are horizontally distributed. The distance between the first clamping arm 23 and the second clamping arm 24 is the length of the tube body 92 .

[0035] Furthermore, the end of the first clamping arm 23 is provided with a first clamping opening 25, and the end of the second clamping arm 24 is provided with a second clamping opening 26. The outer sizes of the first clamping opening 25 and the second clamping opening 26 match the outer shapes of the electrode sheet 91. In the present invention, the free ends of the first clamping arm 23 and the second clamping arm 24 are provided with a first clamping opening 25 and a second clamping opening 26, respectively. The first clamping opening 25 and the second clamping opening 26 are bent to form a first hook groove 251 and a second hook groove 261. The electrode sheets 91 at both ends of the workpiece 9 are clamped in the hook grooves of the first clamping opening 25 and the second clamping opening 26, so that the electrode sheets 91 can rotate around the side walls of the hook grooves. The restriction of the hook grooves prevents the workpiece from falling off, so that the workpiece can be firmly positioned in the workstation slot 41 and rotate with the welding pad 4. This prevents the workpiece 9 from moving during the welding step, which may cause positional deviation and affect the welding efficiency. In order to facilitate the insertion of the electrode sheet 91, the first hook groove 251 and the second hook groove 261 are set to be trumpet-shaped, and the groove diameters of the first hook groove 251 and the second hook groove 261 gradually increase from one end close to the electrode sheet 91 to the outside to better clamp the electrode sheet 91.

[0036] Furthermore, in order to avoid the shaking problem caused by the excessive length of the first clamping arm 23 and the second clamping arm 24, a fixing plate 22 is provided on the clamping arm bracket 21, and the first clamping arm 23 and the second clamping arm 24 are fixedly installed on the fixing plate 22, thereby improving the stability of the first clamping arm 23 and the second clamping arm 24.

[0037] In this embodiment, the first and second nozzle assemblies 31 and 32 are electrically connected to a discharge box 8, which provides current to the first and second nozzle assemblies 31 and 32. Each of the first and second nozzle assemblies 31 and 32 includes a nozzle support 331, a first nozzle 332, and a second nozzle 333. The first and second nozzles 332 and 333 are respectively mounted on the nozzle support 331. A first nozzle holder 3321 is mounted on the first nozzle 332, and a second nozzle holder 3331 is mounted on the second nozzle 333. When the lead wire 10 enters the first or second nozzle assembly 31 or 32, the first and second nozzle holders 3321 and 3331 clamp the lead wire 10.

[0038] In the present invention, the welding machine frame 1 is provided with a pressure electrode mechanism 5, and the pressure electrode mechanism 5 is used to press the tube body 92 of the workpiece 9 to prevent the workpiece 9 from moving and deviating during welding.

[0039] When the present invention is in operation, the workpiece 9 to be processed is a high-voltage discharge tube. The workpiece 9 to be processed is first installed in the work station slot 41, and the electrode sheets 91 at both ends of the workpiece 9 are clamped and fixed by the clamping arm mechanism 2 and the tube body 92 is pressed by the electrode pressing mechanism 5. Then, the lead wire 10 is clamped by the clamping nozzle mechanism and the lead wire 10 is driven to be electrically welded to the electrode sheets 91 at both ends, so that the lead wire 10 is welded to the electrode sheets 91.

[0040] Furthermore, the welding machine frame 1 is further provided with a wire feeding mechanism 6 and a pressurizing mechanism 7. The wire feeding mechanism 6, pressurizing mechanism 7 and the clamping mechanism are arranged in sequence. The wire feeding mechanism 6 provides the lead wire 10 and feeds the lead wire 10 into the pressurizing mechanism 7. The pressurizing mechanism 7 controls the length of the lead wire 10 and feeds the lead wire 10 into the clamping mechanism.

[0041] The utility model relates to a high-voltage discharge tube pin welding machine. In the utility model, a clamping arm mechanism 2 is provided. The electrode sheets 91 at both ends of a workpiece 9 are clamped by a first clamping arm 23 and a second clamping arm 24, so that the position of the workpiece 9 is further fixed, and the problem of poor contact between the workpiece 9 and the lead 10 caused by displacement during welding is avoided, thereby ensuring welding quality and improving production efficiency.

[0042] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
