Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a pressure fusion welding joint motion fitting base device. Background Art

[0002] Pressure fusion welding is to press the materials to be welded between the upper and lower electrodes under a certain welding pressure, and use the current flowing through the contact surface and adjacent areas of the materials to generate resistance heat, heating the metal to be welded to a local molten state to achieve atomic bonding. This includes ultrasonic welding, which uses high-frequency vibration to generate friction to fuse molecules at high temperature.

[0003] However, in ultrasonic welding, long-term vibration will be accompanied by tiny dust, which can easily cause dust to fall on the surface of the battery cell and cause explosion points in the subsequent welding. When welding the workpiece, sparks will fly and explosion points will occur. If no protection is taken, it is easy for the flying sparks to cause personal injury to the workers, and there is a risk of splashing on the workers' faces.

[0004] Chinese patent document CN118559309A discloses a robot automatic welding device with a safety protection device, including a welding head 1 and a welding head 2 for relative welding, wherein the welding head 1 is connected to a plurality of movable claws driven by an electric telescopic rod, and a transparent cover is opened around the welding head 1 by the movable claws. During the welding process, splashing welding slag is blocked inside the transparent cover to prevent splashing.

[0005] However, in the above solution, the transparent cover needs to be opened by driving the movable claws through the electric telescopic rod. Such a setting not only requires the transparent cover to be opened in advance, but also requires the electric telescopic rod to be controlled, which increases the electrical control cost. Summary of the invention

[0010] Optionally, the first protective plate has a slide groove, a slider is arranged in the slide groove, and the first end of the telescopic column is hingedly connected to the slider.

[0013] Optionally, the free end of the supporting leg has a protective pad, and the provision of the protective pad can prevent slipping and protect the parts to be welded.

[0014] Optionally, the first protective plate has a plurality of ventilation holes for ventilation and heat dissipation during pressure welding.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] In the related art, during welding, a protective cover is usually deployed around the welding head through electric drive to prevent sparks from flying. However, the protective cover deployed by electric control drive cannot move synchronously with the welding head; that is, when the welding head contacts the workpiece to be welded, it cannot be guaranteed that the opening angle of the protective cover driven by electric control is just enough to contact the workpiece to be welded at the same time. Therefore, a certain distance is usually required between the protective cover driven by electric control and the workpiece to be welded to prevent the protective cover from affecting the operation of the welding head, which leads to the problem of lax protection. In addition, when welding the workpiece to be welded, the workpiece to be welded is prone to deformation during welding.

[0023] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0024] like Figure 1 As shown, a specific implementation of the pressure-fusion welding joint motion fitting base device provided in this embodiment includes: a first welding head 1 and a second welding head 2, the first welding head 1 and the second welding head 2 are arranged opposite to each other, the part to be welded 17 is stacked between the first welding head 1 and the second welding head 2, and the part to be welded 17 is welded by the first welding head 1 and the second welding head 2.

[0025] like Figure 2As shown, a first protective device is provided on the first welding head 1, and the first protective device includes: a top plate 3 and a plurality of first protective plates 4 arranged around the top plate 3, and the top plate 3 is suitable for passing through the first welding head 1.

[0026] like Figure 2 As shown, a plurality of first protective plates 4 form a first protective cavity, the first protective plate 4 is rotatably connected to the top plate 3, the end of the first protective plate 4 away from the top plate 3 is inclined toward a direction away from the first protective cavity, and a first elastic member is connected to the first protective plate 4, the first elastic member has a damping force for damping the deflection of the first protective plate 4 toward a direction away from the first protective cavity.

[0027] The pressure fusion welding joint motion fitting base device provided in this embodiment protects spark splashing and explosion points during workpiece welding through the first protective device on the first welding head 1, thereby preventing flying sparks from causing personal injury to workers.

[0028] like Figure 3 As shown, during operation, when the bottom end of the first protective plate 4 abuts against the workpiece 17 to be welded, multiple first protective plates 4 can be automatically deployed for protection without the need for electric control drive, thus saving electric control costs; during the welding process, the first protective plate 4 can automatically maintain close contact with the workpiece 17 to be welded under the action of the first elastic member, and in the process of the first protective plate 4 pressing against the workpiece 17 to be welded, the problem of deformation of the workpiece 17 to be welded during welding can be prevented.

[0029] like Figure 2 As shown, in one embodiment, the first elastic member includes: a telescopic column 5 and a spring connected to the telescopic column 5, the first end of the telescopic column 5 is hingedly connected to the first protective plate 4, and the spring has an elastic force driving the telescopic column 5 to move in a direction close to the first protective plate 4. Specifically, the lower end of the telescopic column 5 is hingedly connected to the first protective plate 4, so that when the first protective plate 4 is flipped, the telescopic movement of the telescopic column 5 is not affected. This embodiment can ensure the stability of the force used to damp the first protective plate 4 through the cooperation of the spring and the telescopic column 5. Of course, the above description is not restrictive, and in some alternative embodiments, the first elastic member can also adopt other structures.

[0030] like Figure 4As shown, in one embodiment, the first protective plate 4 has a slide groove 6, a slider 7 is arranged in the slide groove 6, and the first end of the telescopic column 5 is hingedly connected to the slider 7. Through the above arrangement, when the first protective plate 4 is flipped, the slider 7 slides in the slide groove 6, and the telescopic column 5 always remains in a vertical state, thereby ensuring that the telescopic column 5 provides a stable damping force to the first protective plate 4. Of course, the above description is not restrictive, and in some alternative embodiments, the structures of the slide groove 6 and the slider 7 can be omitted. For example, the telescopic column 5 can be hinged at both ends.

[0031] like Figure 2 As shown, in one embodiment, the top plate 3 is provided with a connecting ear 8, and the telescopic column 5 is slidably inserted into the connecting ear 8. Specifically, a spring is sleeved on the portion of the telescopic column 5 that passes upward through the connecting ear 8, the connecting ear 8 is connected to one end of the spring, and the top end of the telescopic column 5 is connected to the other end of the spring, which can be specifically connected by welding or hooking. With such an arrangement, when the telescopic column 5 slides upward, a stable damping force can be provided by the tensile force of the spring. Of course, the above description is not restrictive, and in some alternative embodiments, the connecting ear 8 can be omitted, and the telescopic column 5 can also be connected to the top plate 3 using other structures.

[0032] like Figure 2 , Figure 3 As shown, in one embodiment, legs 9 are provided at the four corners of the top plate 3, and the legs 9 are located between two adjacent first protective plates 4, and the legs 9 have elastic telescopic sections. The gap between two adjacent first protective plates 4 can be made up by four legs 9, and when the welded part 17 is abutted, the elastic telescopic section is extended to ensure the abutting force of the legs 9 on the welded part 17, and such a setting can avoid the risk of deformation of the workpiece when the welded part is subjected to downward pressure welding.

[0033] like Figure 2 As shown, in one embodiment, the free end of the leg 9 has a protective pad 10, and the protective pad 10 may be provided with anti-skid patterns. The provision of the protective pad 10 can prevent skidding and protect the welded part 17. Of course, the above description is not restrictive, and in some alternative embodiments, the protective pad 10 may be omitted.

[0034] like Figure 4 As shown, in one embodiment, the first protective plate 4 has a plurality of vent holes 11. By providing the vent holes 11, it is possible to better facilitate ventilation and heat dissipation during welding of the workpiece 17 to be welded, thereby preventing heat accumulation from being unable to be discharged and affecting the welding effect. Of course, the above description is not restrictive, and in some alternative embodiments, the vent holes 11 can be omitted.

[0035] like Figure 4 As shown, in one embodiment, a plurality of the vent holes 11 are arranged in an array on the first protective plate 4. With this arrangement, the vent holes 11 can be arranged smaller, that is, ventilation and heat dissipation can be performed, and welding sparks can be avoided. Of course, the above description is not restrictive, and in some alternative embodiments, the vent holes 11 can also be arranged in other forms.

[0036] like Figure 5 As shown, in one embodiment, a second protective device is provided on the second welding head 2, and the second protective device includes: a bottom plate 12 and a plurality of second protective plates 13 arranged around the bottom plate 12, the bottom plate 12 is suitable for passing through the second welding head 2, the second protective plates 13 are obliquely connected to the bottom plate 12, and the plurality of second protective plates 13 form a second protective cavity; specifically, the second protective plate 13 and the bottom plate 12 can be fixedly connected by welding. Of course, the above description is not restrictive, and in some alternative embodiments, the second protective device can be omitted.

[0037] like Figure 5 As shown, a second elastic member 14 is connected to the base plate 12, and the second elastic member 14 has a damping force to damp the second welding head 2 from penetrating into the second protective cavity. Specifically, a mounting plate 18 is connected to the second welding head 2, and the second elastic member 14 is connected between the mounting plate 18 and the base plate 12. The mounting plate 18 can be fixedly connected to the second welding head 2 by welding, or can be connected to the second welding head 2 by other means such as a snap connection and a threaded connection. The second welding head 2 is slidably connected to the base plate 12, so that the second welding head 2 can be inserted into the second protective cavity. Of course, the above description is not restrictive, and in some alternative embodiments, the second elastic member 14 can be omitted.

[0038] In this embodiment, the second protective plate 13 is provided to protect the surroundings of the second welding head 2. When the second welding head 2 moves toward the workpiece 17 to be welded, the damping force provided by the second elastic member 14 is used to transfer the force of the second welding head 2 to the second protective plate 13, and the workpiece 17 to be welded is abutted by the second protective plate 13, thereby avoiding the risk of deformation of the workpiece during downward pressure welding.

[0039] like Figure 5As shown, in one embodiment, one end of the second protective plate 13 that is used to abut against the workpiece 17 to be welded is connected to a tilted bar 15 through a third elastic member 16, and the third elastic member 16 has an elastic force that drives the tilted bar 15 to move toward the direction close to the workpiece 17 to be welded. The tilted bar 15 is used to directly abut against the workpiece 17 to be welded, which can facilitate the protection of the edge, greatly improve the protection against sparks generated during the welding process, avoid splashing and avoid deformation of the workpiece. The third elastic member 16 is used to provide an elastic abutment force to the tilted bar 15, thereby ensuring stable abutment against the workpiece 17 to be welded. Of course, the above description is not restrictive, and in some alternative embodiments, the tilted bar 15 can be omitted.

[0040] like Figure 6 As shown, the tilting bar 15 is installed on the second protective plate 13 in a floating manner through a fastener 19, and the fastener 19 passes through the second protective plate 13 from the bottom and is connected to the tilting bar 15 through a threaded structure. A third elastic member 16 is sleeved on the fastener 19, and the bottom end of the third elastic member 16 is fixedly connected to the fastener 19, and the top end of the third elastic member 16 is fixedly connected to the second protective plate 13. Through this arrangement, in a free state, under the action of the fastener 19, the tilting bar 15 floats on the second protective plate 13. When the tilting bar 15 abuts against the part to be welded 17, the tilting bar 15 moves downward to stretch the third elastic member 16, and the tensile force of the third elastic member 16 keeps the tilting bar 15 in continuous abutment against the part to be welded 17. Of course, the above description is not restrictive, and in some alternative embodiments, the third elastic member 16 can be omitted. For example, the tilting bar 15 can be fixedly installed on the second protective plate 13.

[0041] like Figure 1 As shown, in this embodiment, the second welding head 2 is mounted on a fixing plate 20 , and a plurality of mounting holes 21 are provided on the fixing plate 20 . The fixing plate 20 is mounted through the mounting holes 21 , thereby ensuring the stability of the second welding head 2 .

[0042] Working principle: like Figure 1 As shown, the pressure fusion welding joint motion fitting base device provided in this embodiment, when in use, the welding parts of the two parts to be welded 17 are stacked, and the first welding head 1 and the second welding head 2 are relatively arranged at the upper and lower ends of the welding parts.

[0043] like Figure 3As shown, in the process of the first welding head 1 approaching downward toward the workpiece 17 to be welded, the bottom ends of the four legs 9 and the second protective plate 13 respectively abut against the workpiece 17 to be welded. As the first welding head 1 continues to approach the workpiece 17 to be welded, the four legs 9 retract upward and the second protective plate 13 tilts and expands outward, thereby protecting the surroundings of the first welding head 1 while abutting against the workpiece 17 to be welded.

[0044] like Figure 6 As shown, during the process of the second welding head 2 approaching the workpiece 17 to be welded, the top end of the inclined bar 15 abuts against the workpiece 17 to be welded, and as the second welding head 2 continues to approach the workpiece 17 to be welded, the third elastic member 16 is stretched and the second elastic member 14 is compressed, so that the inclined bar 15 maintains continuous abutment against the workpiece 17 to be welded. Thus, during the welding process of the workpieces, the problem of deformation of the workpiece 17 to be welded during welding can be prevented.

[0045] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
