Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and in particular relates to a welding device. Background Art

[0002] In the use of handheld electric welding pens, the welding pen tip is a key component for transferring heat energy and performing welding. The welding pen tip in the prior art is usually fixed to the welding pen body by a threaded connection. When the user needs to replace a different type or a damaged welding pen tip, he must manually rotate it to unscrew the old welding pen tip and install a new welding pen tip. Although this traditional threaded connection method is simple, it is cumbersome to operate and wastes time, especially in a working environment where the welding pen tip is frequently replaced. In addition, during the replacement process, the temperature of the welding pen tip is extremely high, which can easily cause burns to the user, and the welding pen tip is fragile at high temperatures and may be damaged if not handled with care, increasing maintenance costs. Existing tools often lack containers specifically for placing high-temperature welding pen tips, which increases the difficulty of operation and safety risks. Utility Model Content

[0003] The purpose of the utility model is to at least solve the problem of how to quickly replace the soldering pen tip. This purpose is achieved through the following technical solutions:

[0004] The utility model provides a welding device, comprising:

[0005] A soldering pen body, the soldering pen body comprising a soldering pen body and at least two soldering pen tips, the soldering pen body being selectively connectable to any of the soldering pen tips in a detachable manner, and a locking block being provided on the outer circumference of each of the soldering pen tips;

[0007] According to the welding device of the utility model, the welding pen tip can be quickly and safely replaced by cooperating with the locking block on the welding pen tip and the locking member in the base receiving groove. The user inserts the welding pen tip axially into the corresponding receiving groove through a simple insertion action, and the locking block can then enter the locking groove and closely contact with its inner wall, thereby achieving a stable locking, and then pulls out the welding pen body in a direction away from the receiving groove to separate the welding pen tip from the welding pen body. When the next welding pen tip needs to be replaced, it is only necessary to align the welding pen body with another welding pen tip and squeeze it so that the welding pen body and the welding pen tip are engaged and matched to complete the replacement step. In addition, the design of the opening allows the locking block to easily pass into the locking groove, thereby greatly simplifying the docking process. The welding device provided by the utility model solves the problems of cumbersome operation, long time consumption, high safety risk and easy damage of the welding pen tip in the replacement of traditional welding pen tips through a locking mechanism. The welding device allows the welding pen tip to be quickly locked in the receiving groove of the base through a simple insertion action without the need for complex manual operation or auxiliary tools. This design not only significantly improves the efficiency of replacing the soldering pen tip and reduces the operation time, but also greatly reduces the risk of burns because the soldering pen tip does not need to be directly held by hand for replacement. At the same time, the precise mechanical fit also reduces the damage to the soldering pen tip caused by improper operation and prolongs its service life. In addition, the receiving groove of the base provides a safe storage location for the soldering pen tip, protects the soldering pen tip from collision, maintains the cleanliness of the working environment, and further reduces the risk of damage.

Therefore, the example term "below..." can include both above and below orientations.

[0041] like Figures 1 to 14As shown, according to the embodiment of the utility model, a welding device 100 is proposed, which includes a welding pen body 10 and a base 20. The welding pen body 10 includes a welding pen body 12 and at least two welding pen heads 11. The welding pen body 12 can be selectively connected to any welding pen head 11 in a detachable manner. A locking block 111 is provided on the outer circumferential surface of each welding pen head 11. The base 20 is provided with at least two accommodating grooves 201. At least two welding pen heads 11 can be accommodated in the at least two accommodating grooves 201 in a one-to-one correspondence. A locking member 21 protruding from the inner circumferential surface is provided on the inner circumferential surface of the accommodating groove 201. A locking groove is provided on the locking member 21, and the locking groove can accommodate the locking block 111. Along the axial direction of the welding pen head 11, the locking block 111 can abut against the inner wall of the locking groove. An opening is also provided on the locking member 21, and the opening is connected to the locking groove, and the size of the opening is larger than the size of the locking block 111.

[0042] According to the welding device 100 of the utility model, the welding tip 11 can be quickly and safely replaced by cooperating the locking block 111 on the welding tip 11 with the locking member 21 in the receiving groove 201 of the base 20. The user inserts the welding tip 11 axially into the corresponding receiving groove 201 through a simple insertion action, and the locking block 111 can then enter the locking groove and closely contact its inner wall, thereby achieving a stable lock, and then pull out the welding body 12 in a direction away from the receiving groove 201, so that the welding tip 11 is separated from the welding body 12. When the next welding tip 11 needs to be replaced, it is only necessary to align the welding body 12 with another welding tip 11 and squeeze it so that the welding body 12 and the welding tip 11 are engaged and matched, and the replacement step is completed. In addition, the design of the opening allows the locking block 111 to easily pass into the locking groove, thereby greatly simplifying the docking process. The welding device 100 provided by the utility model solves the problems of cumbersome operation, long time consumption, high safety risk and easy damage of the welding pen tip 11 in the replacement of the traditional welding pen tip 11 through a locking mechanism. The welding device 100 allows the welding pen tip 11 to be quickly locked in the receiving groove 201 of the base 20 through a simple insertion action, without complicated manual operation or auxiliary tools. This design not only significantly improves the efficiency of replacing the welding pen tip 11 and reduces the operation time, but also greatly reduces the risk of burns because the welding pen tip 11 does not need to be directly hand-held for replacement. At the same time, the precise mechanical matching also reduces the damage to the welding pen tip 11 caused by improper operation and prolongs its service life. In addition, the receiving groove 201 of the base 20 provides a safe storage position for the welding pen tip 11, protects the welding pen tip 11 from collision, maintains the cleanliness of the working environment, and further reduces the risk of damage. In general, the utility model provides an efficient, safe and convenient solution for the rapid replacement of the welding pen tip 11, which greatly optimizes the operational convenience and safety of the welding operation.

[0043] like Fig.11As shown, it can be understood that the locking member 21 includes a first locking portion 211 and a second locking portion 212, and the first locking portion 211 and the second locking portion 212 are arranged at intervals along the axial direction of the soldering pen tip 11, and the first locking portion 211 and the second locking portion 212 are surrounded to form a locking groove. The first locking portion 211 and the second locking portion 212 arranged at intervals along the axial direction of the soldering pen tip 11 can provide support or clamping force in both the upper and lower directions to the locking block 111 inserted into the locking groove, which not only increases the contact area, but also improves the overall locking stability. At the same time, the locking groove formed by the first locking portion 211 and the second locking portion 212 reduces the wear caused by vibration or frequent operation. This locking groove can distribute the pressure more evenly, thereby reducing the wear of a single point and extending the service life of the soldering pen tip 11.

[0044] Specifically, the side of the first locking portion 211 facing the second locking portion 212 is an inclined structure 2111. Along the direction away from the opening, the inclined structure 2111 gradually reduces the storage space of the locking groove. In order to cooperate with the inclined structure 2111 of the first locking portion 211, the side of the second locking portion 212 facing the first locking portion 211 is a planar structure. The inclined structure 2111 plays a guiding role during the insertion process of the soldering pen tip 11, helping the locking block 111 to slide smoothly into the locking groove. As the locking block 111 goes deeper, the inclined structure 2111 can accurately guide the locking block 111 to the final locking position, thereby achieving accurate and fast automatic positioning. Because the inclined structure 2111 gradually reduces the width of the locking groove along the insertion direction, this provides an increasing clamping force for the locking block 111. When the locking block 111 is fully inserted, the inclined surface structure 2111 ensures that the locking block 111 is tightly clamped in the locking groove. Such an inclined surface structure 2111 greatly improves the stability of the lock and avoids loosening due to vibration or other external forces during use. This design allows the user to more easily complete the insertion and removal actions when replacing the soldering pen tip 11 without applying additional force or performing complicated operating steps. The installation and removal of the soldering pen tip 11 becomes more intuitive and quick. The inclined surface structure 2111 reduces physical impact and friction while guiding the locking block 111, reduces the wear of the locking components, thereby extending the service life of the soldering pen tip 11 and the locking device, and reducing maintenance costs.

[0045] Specifically, the inclination angle of the inclined surface structure 2111 is within the range of 5°-10°. By setting the inclination angle of the inclined surface between 5° and 10°, it can be ensured that the locking block 111 is appropriately guided and pressed during the insertion process. This angle is neither too large to cause excessive insertion resistance, nor too small to cause an insignificant locking effect, thereby achieving smooth entry and firm fixation of the locking block 111. This angle range can effectively improve the reliability of the locking structure without sacrificing ease of operation. When the locking block 111 fully enters the locking groove, the inclined surface structure 2111 ensures that it forms a close contact with the inner wall of the locking groove, enhances the anti-vibration ability after locking, and ensures that the soldering tip 11 will not loosen or fall off during use. Setting the inclination angle of the inclined surface within this range helps to reduce the friction between the locking block 111 and the locking groove, thereby reducing the wear of the components. This optimized contact angle reduces the physical impact on the soldering tip 11 and the locking device, effectively extending the maintenance cycle and service life of the equipment. The appropriate bevel angle enables the operator to push the soldering pen tip 11 into the locking groove with less force, and also to easily pull it out of the locking groove, which not only improves the efficiency of replacing the soldering pen tip 11, but also reduces the physical burden during operation.

[0046] like Figure 13 to Figure 14 As shown, in some embodiments, at least two locking members 21 are provided on the inner circumferential surface of the receiving groove 201, and all the locking members 21 are arranged at intervals along the circumference of the welding pen tip 11, and the locking block 111 can be received in the locking groove of one of the locking members 21, and the sides of at least two locking members 21 facing the welding pen tip 11 are in contact with the welding pen tip 11. By arranging multiple locking members 21 in the receiving groove 201, the welding pen tip 11 can be firmly fixed from multiple directions. This multi-point locking mechanism greatly enhances the stability and reliability of the welding pen tip 11 during use, ensuring that the welding pen tip 11 will not loosen or fall off. The use of multiple locking members 21 disperses the pressure on the welding pen tip 11 and reduces the local wear or damage that may be caused by a single locking point. This distributed locking method helps to protect the welding pen tip 11 and extend its service life. Since the receiving groove 201 is provided with multiple locking members 21, the operator can select any locking groove aligned with the locking block 111 for fixing when installing the welding pen tip 11. This increases the flexibility of the device, allowing the operator to more flexibly adjust the position of the welding pen head 11 as needed. In addition, the design of multiple locking members 21 also improves the robustness and durability of the entire welding device 100.

[0047] Specifically, the side of the locking piece 21 facing the soldering pen tip 11 is an arc surface, and the arc surface fits the outer peripheral surface of the soldering pen tip 11. The arc surface design makes the contact area between the locking piece 21 and the soldering pen tip 11 larger, and this large area of ​​contact helps to evenly distribute the pressure, thereby reducing the wear or damage caused by excessive local pressure. This not only prolongs the service life of the soldering pen tip 11 and the locking piece 21, but also protects the soldering pen tip 11 from deformation or damage that may be caused by excessive pressure. The arc surface structure can fit more closely with the outer peripheral surface of the soldering pen tip 11, and this fitting method provides a more stable support for the soldering pen tip 11. The tight fit can effectively prevent the soldering pen tip 11 from moving or loosening in the locking groove, thereby enhancing the overall stability and reliability. Because the arc surface design fits the outer peripheral shape of the soldering pen tip 11, the installation and removal process of the soldering pen tip 11 is smoother. When the soldering pen tip 11 is inserted into the locking groove, the arc-shaped locking member 21 can naturally guide the soldering pen tip 11 into place, reducing possible friction and resistance during installation, while also simplifying the disassembly process and improving operating efficiency.

[0048] Specifically, the locking block 111 can be spherical. Due to the complete symmetry of its shape, the spherical locking block 111 can automatically find and locate the center point in the locking groove. This automatic centering feature greatly simplifies the insertion and installation process of the soldering pen tip 11, ensuring that the soldering pen tip 11 can be correctly and quickly installed in the appropriate position. Since the sphere can be freely adjusted in the locking groove, this reduces poor contact or welding errors caused by improper installation angles. When installing or replacing the soldering pen tip 11, the operator does not need to accurately adjust the angle of the soldering pen tip 11 to match the locking device. The design of the spherical locking block 111 allows for quick and intuitive insertion and removal, significantly improving operational efficiency and convenience. In addition, the spherical locking block 111 rolls in the locking groove, and compared with locking blocks 111 of other shapes, its contact surface will be evenly stressed during use, thereby reducing local wear. This evenly distributed force extends the service life of the locking block 111 and the locking groove.

[0049] like Figures 7 and 8 As shown, specifically, the locking block 111 can be a diamond-shaped structure. The diamond-shaped locking block 111 has good self-guiding properties due to its unique geometric shape. When inserted into the locking groove, the sharp corners of the diamond-shaped locking block 111 can help the soldering pen tip 11 automatically align with the entrance of the locking groove, reducing the precise operation required for alignment, making the insertion process smoother and faster. After the diamond structure is fully inserted into the locking groove, its wide side can effectively contact the inner wall of the locking groove, providing a larger contact area and increasing friction, thereby achieving a more stable locking.

[0050] Specifically, the number of locking blocks 111 is the same as the number of locking members 21, and the locking blocks 111 are received in the locking grooves of the multiple locking members 21 one by one. Each locking block 111 specifically corresponds to a locking groove of a locking member 21, and such a design ensures that the soldering pen tip 11 can be accurately positioned at its intended position.

[0051] In some embodiments, an annular locking member 21 is provided on the inner circumference of the receiving groove 201, an annular locking groove is provided in the middle of the annular locking member 21, and an opening is provided above the annular locking member 21. The locking block 111 of the soldering pen tip 11 can enter the annular locking groove from the opening, and the soldering pen tip 11 can be completely accommodated in the locking groove by rotating along the axial direction of the soldering pen tip 11. The soldering pen tip 11 can be replaced by plugging and unplugging the soldering pen body 12 up and down. When the locking block 111 of the soldering pen tip 11 is accommodated in the locking groove, the inner circumference of the annular locking member 21 can fit tightly against the outer circumference of the soldering pen tip 11. The annular locking groove allows the locking block 111 of the soldering pen tip 11 to enter directly from the upper opening, and then the soldering pen tip 11 is locked by a simple rotation action, which greatly simplifies the loading and unloading process of the soldering pen tip 11, making the replacement of the soldering pen tip 11 both quick and easy, and improving work efficiency. In addition, the annular locking member 21 forms a complete annular contact around the periphery of the welding pen tip 11, which not only increases the contact area but also improves the stability of the locking. The annular locking groove ensures that the locking block 111 will not loosen or fall off under any operating conditions, especially in high vibration or heavy load welding operations.

[0052] In some embodiments, a locking member 21 is provided on the receiving groove 201, and a locking groove with a certain depth is provided in the locking member 21, and the locking block 111 on the soldering pen tip 11 can be fully inserted into the locking groove, and the locking groove fully clamps the locking block 111. The depth of the locking groove allows the locking block 111 to be fully inserted, which ensures that the locking block 111 can be firmly clamped during the welding process. This fully enclosed clamping method significantly increases the stability of the soldering pen tip 11 and reduces displacement or falling off due to vibration or accidental collision. The design of the locking groove makes it very direct and simple to insert and remove the soldering pen tip 11. The operator only needs to align the locking block 111 of the soldering pen tip 11 with the locking groove and easily push it in, without the need for additional rotation or adjustment, which greatly simplifies the operating steps of replacing the soldering pen tip 11 and improves work efficiency.

[0053] It is understandable that the soldering pen body 12 is provided with a mounting hole, and one end of the soldering pen tip 11 is inserted into the mounting hole and engaged with the mounting hole, specifically, an interference fit. Since the soldering pen tip 11 can be directly inserted into the mounting hole on the soldering pen body 12 and fixed by interference fit, this simplifies the installation and replacement process of the soldering pen tip 11. The operator can quickly insert or remove the soldering pen tip 11, thereby improving work efficiency, which is particularly suitable for occasions where the soldering pen tip 11 needs to be frequently replaced.

[0054] like Figure 6 As shown, it can be understood that the soldering pen body 10 also includes a soldering pen tail 13, and the soldering pen tail 13 includes a shell 131, a display screen 132 and a button 133, and the soldering pen tail 13 is connected to the power cord 14. The display screen 132 and the button 133 are arranged on the shell 131, and the shell 131 of the soldering pen tail 13 can be made of high temperature resistant and electrically insulating materials, such as engineering plastics or metal materials with appropriate insulation treatment. The display screen 132 is installed on the front side or upper side of the shell 131 of the soldering pen tail 13, so that the user can easily view it during use. The display screen 132 generally adopts LCD or OLED technology, because these technologies provide clear display effects and a wide viewing angle, ensuring that information can be clearly read under different ambient light. In addition, the surface of the display screen 132 is usually equipped with anti-scratch and anti-reflective coatings to protect the screen from being scratched and can also display clearly under strong light. The operation button 133 is arranged around or below the display screen 132, so that the user can easily operate while observing the display screen 132. These buttons 133 are usually physical buttons 133, because the physical buttons 133 give obvious tactile feedback when operated, which is suitable for use in industrial environments, especially when operated with gloves. The design of the buttons 133 should take into account the needs of dust and water resistance to adapt to various working environments. There is usually a corresponding function mark next to each operation button 133, which clearly indicates the function of the button 133 (such as temperature increase, decrease, power switch, etc.). These marks help users quickly identify the function of the button 133 and improve the intuitiveness and efficiency of the operation.

[0055] Specifically, the soldering pen tail 13 is connected to the power cord 14, and a heating element is provided in the soldering pen head 11, and the resistance of the heating element will cause the electrical energy to be converted into heat energy. The power cord 14 is connected to the interface of the soldering pen tail 13, and transmits the current to the soldering pen head 11 through the wire inside the soldering pen body 10. In order to accurately control the temperature of the soldering pen head 11, the soldering pen body 10 is usually equipped with a temperature sensor and a control circuit. These control circuits can automatically adjust the current according to the preset temperature setting, thereby controlling the heat output of the heating element. The temperature control system ensures that the soldering pen head 11 works within a suitable temperature range to prevent damage to the solder or electronic components due to excessive temperature. In addition, the power cord 14 also supplies power to the display screen 132 and the button 133 at the same time.

[0056] like Fig. 9 and Fig.13As shown, it can be understood that the receiving slots 201 are evenly detected and opened on the same side of the base 20. All the receiving slots 201 are evenly distributed on the same side of the base 20, so that the user can more easily access these slots when using or replacing the soldering pen tip 11. This layout optimizes the convenience of operation, especially in a working environment with limited space, which can reduce the user's movement between different positions and improve work efficiency. All the receiving slots 201 are arranged on the same side, so that maintenance personnel can easily check and maintain all soldering pen tips 11. This helps to quickly identify and solve problems and improve the maintenance efficiency of the equipment.

[0057] like Fig.12 As shown, it can be understood that the locking groove is in the shape of a ring with a notch structure, and the notch structure is connected to the opening. The notch structure design of the locking groove allows the locking block 111 on the soldering pen tip 11 to be more easily inserted into or removed from the locking groove. The presence of the notch reduces the alignment accuracy and force required for insertion and removal, making the entire operation more convenient and faster. This is especially beneficial for users who need to frequently replace the soldering pen tip 11, and can significantly improve work efficiency. The ring-shaped locking groove design provides a stable locking function.

[0058] It is understood that the method of using the welding device 100 in this embodiment is that the user first inserts the welding pen tip 11 to be replaced into the receiving groove 201 of the base 20. At this time, the position of the welding pen tip 11 should be correctly aligned so as to enter the next step of operation. Then, the user rotates the welding pen body 10 clockwise. This action causes the locking block 111 on the welding pen tip 11 to enter the locking groove set on the receiving groove 201. The upper surface of the locking groove is an inclined surface, so as the welding pen tip 11 continues to rotate, the locking block 111 will be guided by the inclined surface and gradually clamped in the locking groove. Once the locking block 111 is clamped, the welding pen tip 11 is firmly fixed in the receiving groove 201. At this time, the user can easily pull out the old welding pen tip 11 from the welding pen body 12. Then, the user inserts the new welding pen tip 11 into the welding pen body 12. The installation of the new welding pen tip 11 should ensure that it is correctly aligned and fixed. After the installation of the new soldering pen head 11 is completed, the user needs to rotate the handheld soldering pen counterclockwise so that the locking block 111 will be loosened from the locking groove. Finally, the user takes the soldering pen body 10 out of the base 20 to complete the replacement process of the entire soldering pen head 11.
