[0020] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0022] Welding machine mainframes typically feature a card-swiping function. The card-swiping function primarily serves for equipment access management and personnel qualification verification. For example, by binding the welding machine to an IC card or ID card, the card-swiping system can verify whether the operator possesses the necessary qualifications. For instance, scanning the welding machine's QR code requires a valid special operation certificate; otherwise, the equipment cannot start, preventing unlicensed operation and reducing the risk of illegal operation. The card-swiping system can restrict unauthorized personnel from operating the equipment, allowing only certified and qualified personnel to use specific welding machines. This hierarchical control mechanism reduces the probability of misoperation and ensures safe equipment operation. Card-swiping records are linked to welding machine usage data, forming a complete "person-machine-time-location" operation trajectory. When quality issues arise, information such as the operator, parameter settings, and time can be quickly traced.

[0023] A welding machine main unit typically includes a housing and electrical components and an operation panel assembly housed within the housing. The operation panel assembly contains a main circuit board that is electrically connected to the electrical components. The card swiping area is usually located on the main circuit board. However, some customers do not require card swiping functionality. For these customers, the addition of card swiping functionality to the welding machine main unit increases the purchase cost.

[0024] This application separates the card reader circuit board from the main circuit board, and the two are detachably connected, so that the card reader circuit board can be used as an optional accessory, which can reduce the purchase cost for customers who do not need card reading.

[0025] To facilitate the reader's understanding of the concept of this utility model, the specific structure of the welding machine host is described below: Please see Figure 1-3 The welding machine host 100 includes a housing 1, electrical components 2, and an operation panel assembly 3. The electrical components 2, housed within the housing 1, are the main power conversion mechanism and may include the welding machine's overall control board, power board, etc. The operation panel assembly 3 includes an operation panel 31, a main circuit board 32, and a card reader circuit board 33. The operation panel 31, located within the housing 1, includes a display device and buttons for user observation and operation of the welding machine host 100. The main circuit board 32 is located on the operation panel 31 and is electrically connected to the electrical components 2. Signal exchange occurs between the main circuit board 32 and the electrical components 2 to control the welding process. The card reader circuit board 33 is detachably connected to the main circuit board 32 and provides card-swiping functionality. Wireless communication technologies such as RFID, NFC, Bluetooth, 5G, infrared, and ultrasonic technologies are used to meet the needs of card-swiping scenarios. When card swiping is required, the card swiping circuit board 33 can be installed and connected to the main circuit board 32. When card swiping is not required, the card swiping circuit board 33 can be removed from the main circuit board 32, making the card swiping circuit board 33 an optional accessory. Customers who do not require card swiping can purchase a welding machine host 100 without the card swiping circuit board 33, thereby reducing the purchase cost for customers who do not require card swiping. This application makes the card swiping circuit board 33 independent of the main circuit board 32, with the two detachably connected, so that the card swiping circuit board 33 can be used as an optional accessory, reducing the purchase cost for customers who do not require card swiping. The card swiping circuit board 33 can also be purchased separately, with a lower purchase cost and convenient customer customization.

[0026] In some embodiments, the card reader circuit board 33 is located between the operation panel 31 and the main circuit board 32, which facilitates the connection between the card reader circuit board 33 and the main circuit board 32, and also makes it easier for the user to swipe the card near the operation panel 31.

[0027] In some embodiments, the operation panel 31 is provided with a display screen and buttons to facilitate user observation and operation of the welding machine host 100.

[0028] In some embodiments, the welding machine host 100 further includes a sixth screw connector 41 and a seventh screw connector 42. The sixth screw connector 41 is fixed to the operation panel 31, and a portion of the seventh screw connector 42 passes through the main circuit board 32 and is screwed to the sixth screw connector 41, so that the main circuit board 32 is detachably fixed to the operation panel 31. The sixth screw connector 41 can be a nut, and the seventh screw connector 42 can be a screw. The sixth screw connector 41 is welded to the operation panel 31.

[0029] In some embodiments, please refer to the following: Figure 4 The operation panel assembly 3 also includes a connector 34, which includes a first sub-connector 341 and a second sub-connector 342. The first sub-connector 341 is connected to the main circuit board 32, and the second sub-connector 342 is connected to the card reader circuit board 33. The first sub-connector 341 is detachably connected to the second sub-connector 342. The card reader circuit board 33 and the main circuit board 32 can transmit electrical signals through the connector 34. In some embodiments, the main circuit board 32 supplies power to the card reader circuit board 33 and performs signal interaction through the connector 34.

[0030] In some embodiments, the first sub-connector 341 is inserted into the second sub-connector 342, and the connector 34 is a pin.

[0031] In some embodiments, please refer to the following: Figure 5 The operation panel assembly 3 also includes a first screw connector 35 and a second screw connector 36. The first screw connector 35 is fixed to the card reader circuit board 33. The main circuit board 32 is provided with a first hole 321. One end of the second screw connector 36 passes through the first hole 321 and is screwed to the first screw connector 35. The other end of the second screw connector 36 abuts against the main circuit board 32 to fix the card reader circuit board 33 to the main circuit board 32.

[0032] In some embodiments, the first screw connector 35 is provided with a threaded hole, and the sidewall of the second screw connector 36 is provided with threads. The second screw connector 36 is screwed into the threaded hole of the first screw connector 35.

[0033] In some embodiments, the main circuit board 32 is provided with a first support post 322, which abuts against a first screw connector 35. The first support post 322 is provided with a second hole 3221, which communicates with the first hole 321. One end of the second screw connector 36 passes through the first hole 321 and the second hole 3221 in sequence and is screwed to the first screw connector 35. The first support post 322 can reduce the possibility of the main circuit board 32 being damaged by the first screw connector 35.

[0034] In some embodiments, the second sub-connector 342 and the first screw connector 35 are respectively disposed at both ends of the card reader circuit board 33. The connector 34 can also assist in fixing the card reader circuit board 33 and the main circuit board 32. Through the cooperation of the connector 34, the first screw connector 35 and the second screw connector 36, the stability of the connection between the card reader circuit board 33 and the main circuit board 32 can be improved, and the card reader circuit board 33 can be better fixed.

[0035] In some embodiments, please refer to Figure 3 and Figure 6 The surface of the operation panel 31 facing the main circuit board 32 includes a connected coating area 311 and an empty foil area 312. The coating area 311 is provided with an adhesive layer 3111, and the card reader circuit board 33 is disposed in the empty foil area 312. The adhesive layer 3111 of the coating area 311 facilitates the adhesion of other components except the card reader circuit board 33 to the operation panel 31. The card reader circuit board 33 is disposed in the empty foil area 312 without the adhesive layer 3111, which reduces the possibility of the card reader circuit board 33 sticking to the operation panel 31 and facilitates the removal of the card reader circuit board 33. In some embodiments, the empty foil area 312 may also be an opening on the operation panel 31.

[0036] In some embodiments, please refer to Figure 6-8 The welding machine main unit 100 also includes a third screw connector 37. The operation panel 31 is provided with a third hole 313. One end of the third screw connector 37 passes through the third hole 313 and is screwed to the housing 1. The other end of the third screw connector 37 abuts against the operation panel 31, so that the operation panel 31 is detachably fixed to the housing 1, facilitating the installation and removal of the operation panel 31. The housing 1 is provided with a threaded hole, and the side wall of the third screw connector 37 is provided with threads. The third screw connector 37 is screwed into the threaded hole of the housing 1. The third screw connector 37 can be a screw.

[0037] In some embodiments, there are four third holes 313 and four third screw connectors 37. The four third holes 313 are located at the four corners of the operation panel 31, and the four third holes 313 and four third screw connectors 37 correspond one-to-one, which can improve the stability of the operation panel 31. Here, the corner refers to the area near the angle formed by two adjacent edges of the operation panel 31. The shape of the operation panel 31 can be rectangular.

[0038] In some embodiments, please refer to Figure 9-11The welding machine host 100 also includes a fourth screw connector 38, a fifth screw connector 39, and a support member 40. The fourth screw connector 38 is fixed to the operation panel 31, and the fifth screw connector 39 is screwed onto the fourth screw connector 38.

A portion of the fifth screw connector 39 can pass through the support member 40 and be screwed onto the fourth screw connector 38. The fourth screw connector 38 and the fifth screw connector 39 can fix the support member 40. The support member 40 can replace the card swiping circuit board 33 to form a support between the main circuit board 32 and the operation panel 31. When the welding machine host 100 requires card swiping, the operation panel assembly 3 can be removed from the housing 1, the support member 40 can be removed, and the card swiping circuit board 33 can be installed between the operation panel 31 and the main circuit board 32.

[0039] In some embodiments, the fourth screw connector 38 is a press-fit nut, and the fifth screw connector 39 is a screw. The support member 40 can be a plastic part.
