[0046] Reference is made below Figures 1-5 The copper mold pressing structure 100 according to the embodiment of the present application is described.

[0047] As Figures 1-3 shown, the copper mold pressing structure 100 according to the embodiment of the present application comprises a guide block assembly 1, a copper mold assembly 2 and an adjusting limiting piece 3.

[0048] Specifically, as Figures 1-3 shown, the guide block assembly 1 has a cavity 11 extending in the first direction, and the cavity 11 is open at one end in the first direction to form an opening. The copper mold assembly 2 is movably arranged in the cavity 11 in the first direction, and one end of the copper mold assembly 2 is adapted to extend out of the opening and abut against the workpiece 8 to be processed. The adjusting limiting piece 3 is arranged at the end of the guide block assembly 1 away from the opening, and the adjusting limiting piece 3 is used to adjust the position of the copper mold assembly 2 in the first direction.

[0049] It can be understood that, as Figure 5 shown in the example, the copper die pressing structure 100 can be applied to the laser welding device 200, and used to press the workpiece 8 to be processed to ensure that the workpiece 8 to be processed remains stable during the welding process. One end of the copper die assembly 2 along the first direction is arranged in the cavity 11, and the other end extends out of the opening. At the same time, the copper die assembly 2 is movable in the cavity 11 along the first direction. Therefore, when the workpiece 8 to be processed is arranged at the end of the copper die assembly 2 away from the cavity 11, the copper die assembly 2 can be moved along the first direction, so that the end of the copper die assembly 2 located outside the cavity 11 can be in natural abutment with the workpiece 8 to be processed, thereby adapting to workpieces 8 to be processed of different thicknesses, and improving the flexibility and adaptability of the copper die pressing structure 100, thereby reducing the difficulty of the operator in placing, adjusting or replacing the workpiece 8 to be processed, and further shortening the preparation time and improving the production efficiency.

[0050] At the same time, the end of the guide block assembly 1 away from the opening is provided with an adjusting and limiting piece 3, which has a positioning and limiting function. For example, the adjusting and limiting piece 3 can limit the movement range of the copper die assembly 2 along the first direction, so as to adjust the position of the copper die assembly 2 along the first direction. Therefore, when the end of the copper die assembly 2 located outside the cavity 11 is in natural abutment with the workpiece 8 to be processed, the operator can limit the position of the copper die assembly 2 along the first direction by adjusting the adjusting and limiting piece 3, so as to prevent the copper die assembly 2 from moving in the first direction, thereby enabling the copper die assembly 2 to firmly press the workpiece 8 to be processed, preventing the workpiece 8 to be processed from vibrating or moving during the welding process to cause welding defects such as false welding, and ensuring the precision of the overlapping or splicing of the workpiece 8 to be processed, so as to ensure that the penetration and width of the welding position of the workpiece 8 to be processed meet the welding requirements, thereby improving the welding efficiency and quality. At the same time, the copper die pressing structure 100 can ensure that the workpiece 8 to be processed remains stable during the welding process, and is also beneficial to realize automatic welding, thereby further improving the welding efficiency and reducing the labor cost.

[0051] In addition, when the pressing force of the copper die assembly 2 applied to the workpiece 8 to be processed is insufficient or excessive, the operator only needs to adjust the adjusting and limiting piece 3 to adjust the pressing force of the copper die assembly 2 on the workpiece 8 to be processed, which is simple and convenient to operate, and can avoid long-term shutdown adjustment, thereby improving the production efficiency.

[0052] According to the copper mold pressing structure 100, the cavity 11 is arranged in the guide block assembly 1, the copper mold assembly 2 is movable in the cavity 11 along the first direction, and the end of the copper mold assembly 2 extending from the opening abuts against the workpiece 8, and the adjusting limiting piece 3 is arranged at the end of the guide block assembly 1 away from the opening and used for adjusting the position of the copper mold assembly 2 along the first direction, so that the flexibility and adaptability of the copper mold pressing structure 100 are improved, the operator can conveniently place, adjust or replace different workpieces 8, and the operator can also conveniently adjust the pressing force of the copper mold assembly 2 on the workpiece 8, so that the preparation and adjustment time can be shortened and the production efficiency is improved.

[0053] In some embodiments of the utility model, as shown in Figures 1-3 The adjusting limiting piece 3 is movable along the first direction and partially extends into the cavity 11 and is adapted to abut against the copper mold assembly 2. By moving the adjusting limiting piece 3 along the first direction, the length of the adjusting limiting piece 3 extending into the cavity 11 can be adjusted, that is, the position of the end of the adjusting limiting piece 3 abutting against the copper mold assembly 2 along the first direction is adjusted, so that the position of the copper mold assembly 2 along the first direction is limited, and thus the flexibility and adaptability of the copper mold pressing structure 100 are improved, the copper mold assembly 2 can adapt to and press different thicknesses of workpieces 8, so that the accuracy of the overlapping or splicing of the workpieces 8 to be welded can be ensured, the penetration and width of the welding position of the workpiece 8 are ensured to meet the welding requirements, and thus the welding efficiency and quality are improved.

[0054] In some embodiments of the utility model, as shown in Figures 1-3 The copper mold pressing structure 100 further comprises an elastic piece 4, the elastic piece 4 is arranged in the cavity 11, and the elastic piece 4 is located between the copper mold assembly 2 and the adjusting limiting piece 3 along the first direction. The elastic piece 4 can be a heavy load spring and can maintain a certain tension or pressure. When the workpiece 8 is placed at the end of the copper mold assembly 2 away from the cavity 11, the copper mold assembly 2 moves towards the end close to the elastic piece 4, at this time, the elastic piece 4 is in a compressed state between the copper mold assembly 2 and the adjusting limiting piece 3 and can continuously apply pressure to the copper mold assembly 2 and the adjusting limiting piece 3, so that the continuous pressing force of the copper mold assembly 2 on the workpiece 8 can be realized, the pressing effect of the copper mold pressing structure 100 is improved, and thus the welding efficiency and quality of the workpiece 8 are improved.

[0055] In addition, when the copper mold clamping structure 100 moves to different positions of the workpiece 8 to be processed or the copper mold clamping structure 100 abuts against different workpieces 8 to be processed, the elastic force of the elastic member 4 can automatically move and adjust the copper mold assembly 2 along the first direction to adapt to the unevenness of different positions of the workpiece 8 to be processed and the different thicknesses of the workpiece 8 to be processed. This can avoid the copper mold assembly 2 from applying insufficient clamping pressure to the workpiece 8 to be processed, thereby affecting the welding effect, and avoid the copper mold assembly 2 from applying excessive clamping pressure to the workpiece 8 to be processed, thereby damaging the copper mold assembly 2 and the workpiece 8 to be processed.

[0056] At the same time, it can also effectively improve the flexibility and adaptability of the copper mold pressing structure 100, eliminating the need for operators to manually adjust and operate after shutdown, thereby reducing shutdown adjustment time and improving production efficiency.

[0057] In some embodiments of the present invention, Figures 1-3 As shown, the copper mold pressing structure 100 further includes a slider 5, which is disposed in the cavity 11 and is movable along a first direction. The slider 5 is located between the elastic member 4 and the adjustment limit member 3. One end of the slider 5 abuts against the adjustment limit member 3, and the other end is connected to the elastic member 4. The slider 5 can play the role of receiving and transmitting the force between the elastic member 4 and the adjustment limit member 3, thereby ensuring the stability of the transmission between the elastic member 4 and the adjustment limit member 3, thereby ensuring the stability of the elastic member 4 in continuously applying pressure to the copper mold assembly 2 and the adjustment limit member 3, and further ensuring that the copper mold assembly 2 continuously presses the workpiece 8 to ensure the welding effect of the workpiece 8.

[0058] In some embodiments of the present invention, Figures 1-3 As shown, the slider 5 has a protrusion 51, and the side wall of the cavity 11 has a slide groove 111 extending along the first direction. The protrusion 51 is movably arranged in the slide groove 111 along the first direction. The protrusion 51 is provided on the side wall of the slider 5 along the third direction, and the slide groove 111 is provided on the side wall of the cavity 11 along the third direction, so that the protrusion 51 can be inserted into the slide groove 111. At the same time, the slide groove 111 extends along the first direction, so that the protrusion 51 can slide in the slide groove 111 along the first direction, thereby realizing a sliding connection between the slider 5 and the side wall of the cavity 11, facilitating the movement of the slider 5 along the first direction. The structure is simple and easy to implement, wherein the third direction is perpendicular to the first direction.

[0059] Furthermore, there are multiple protrusions 51 and multiple chute 111 corresponding to the protrusions 51. The multiple protrusions 51 and the multiple chute 111 cooperate with each other one by one, which can improve the stability of the sliding connection between the slider 5 and the guide block assembly 1, and improve the uniformity of the force applied to the slider 5, thereby improving the sliding stability of the slider 5. Specifically, as Figure 3In the shown example, the sliding grooves 111 are two, and the protrusions 51 matched with the sliding grooves 111 are also two, of course, the number of the sliding grooves 111 and the protrusions 51 can also be one-to-one three, four, etc.

[0060] In some embodiments of the utility model, as shown in Figures 1-3 As shown, the guide block assembly 1 is provided with a first threaded hole 133, the adjusting limiting piece 3 comprises: an adjusting bolt 31 and a fastening nut 32, the adjusting bolt 31 is arranged in the first threaded hole 133, and the fastening nut 32 is arranged on the adjusting bolt 31 and located on the side of the first threaded hole 133 away from the copper die assembly 2.

[0061] It can be understood that the adjusting bolt 31 is arranged in the fastening nut 32 and the first threaded hole 133, the inner periphery wall of the fastening nut 32 and the first threaded hole 133 is provided with an internal thread, and the external thread on the outer periphery wall of the adjusting bolt 31 is matched with the internal thread on the fastening nut 32 and the first threaded hole 133. Thus, by rotating the adjusting bolt 31, the length of the adjusting bolt 31 extending into the cavity 11 along the first direction can be adjusted, and then the position of the sliding block 5 and the copper die assembly 2 along the first direction can be adjusted, and the compression degree of the elastic member 4 between the sliding block 5 and the copper die assembly 2 can be adjusted, and then the elastic force of the elastic member 4 and the pressing force of the copper die assembly 2 on the workpiece 8 to be processed can be adjusted, which can further enhance the flexibility and adaptability of the copper die pressing structure 100, can ensure the pressing effect of the workpiece 8 to be processed with different thicknesses, and then improve the welding effect and quality. At the same time, the adjustment method is simple and convenient, which can avoid long-time shutdown adjustment, so as to improve the production efficiency.

[0062] In some embodiments of the utility model, as shown in Figures 1-3 As shown, the end face of the copper die assembly 2 facing the adjusting limiting piece 3 is provided with a containing groove 211, and one end of the elastic member 4 is arranged in the containing groove 211. Thus, one end of the elastic member 4 can extend into the containing groove 211 and abut against the bottom wall of the containing groove 211, and the inner periphery wall of the containing groove 211 can position and limit the elastic member 4, avoiding that the elastic member 4 and the copper die assembly 2 cannot be stably connected and transmit the acting force due to the deformation of the elastic member 4, which can effectively improve the stability and reliability of the connection between the elastic member 4 and the copper die assembly 2.

[0063] In some embodiments of the utility model, as shown in Figures 1-3 As shown, the guide block assembly 1 is provided with a notch 122 at one end along the second direction, the notch 122 extends along the first direction and communicates with the cavity 11, the notch 122 is spaced apart from the opening and does not communicate, and the first direction and the second direction are perpendicular, along the second direction, the side of the copper die assembly 2 facing the notch 122 is provided with a limiting protrusion 212, and along the first direction, the limiting protrusion 212 is used for abutting against the inner wall of the notch 122 close to the opening.

[0064] It can be understood that the gap 122 is arranged at one end of the guide block assembly 1 along the second direction, one end of the copper die assembly 2 extends into the cavity 11, the gap 122 is in communication with the cavity 11 and extends along the first direction, so that when the copper die assembly 2 moves along the first direction in the cavity 11, the limiting protrusion 212 can move along the first direction at the gap 122, thereby the adjustability of the position of the copper die assembly 2 can be ensured. At the same time, the gap 122 is spaced apart from the opening and is not in communication, so that when the copper die assembly 2 moves away from the adjusting limiting piece 3, the limiting protrusion 212 can abut against the side wall of the opening along the first direction from the gap 122, thereby the limiting effect can be achieved to prevent the copper die assembly 2 from separating from the cavity 11 at the opening, and the structural integrity and the connection stability of the copper die pressing structure 100 are ensured.

[0065] In some embodiments of the utility model, as shown in Figures 1-3 The copper die assembly 2 comprises a sliding piece 21 and a copper die body 22, the sliding piece 21 extends along the first direction and is arranged in the cavity 11, and the copper die body 22 is connected to one end of the sliding piece 21 extending out of the opening and is used for abutting against the workpiece 8 to be processed. The end of the copper die body 22, which is away from the sliding piece 21, directly abuts against the workpiece 8 to be processed, so the copper die body 22 is more likely to fail due to abrasion, the copper die assembly 2 is divided into the sliding piece 21 and the copper die body 22, the service life of the copper die body 22 is less than that of the sliding piece 21, and after the copper die body 22 is worn out and fails, the original sliding piece 21 can be continuously used by only replacing the copper die body 22, thereby the maintenance cost of the copper die assembly 2 can be reduced.

[0066] In addition, the sliding piece 21 and the copper die body 22 can be made of different materials, the copper die body 22 directly abuts against the workpiece 8 to be processed, and materials with excellent wear resistance and heat resistance such as manganese copper or tin bronze can be used, and the sliding piece 21 can be made of materials such as heat-treated carbon steel or alloy steel, thereby the material and production costs can be reduced.

[0067] In some embodiments of the utility model, the sliding piece 21 and the copper die body 22 are connected through fasteners. The connection stability between the sliding piece 21 and the copper die body 22 can be ensured, and the detachable connection between the sliding piece 21 and the copper die body 22 is realized, so that the copper die body 22 can be easily disassembled in the later period, thereby the maintenance difficulty and the maintenance and replacement costs can be reduced.

[0068] In some embodiments of the utility model, as shown in Figures 1-3 and Figure 5As shown, the copper die pressing structure 100 further comprises a sliding rail 6 extending along a third direction, and the guide block assembly 1 is movably arranged on the sliding rail 6 along the third direction, and the third direction is perpendicular to the first direction. Thus, the movement of the copper die pressing structure 100 in the third direction can be realized, so that the position of the copper die pressing structure 100 abutting and pressing can be changed in the third direction, which facilitates the adjustment of the pre-pressing position of the copper die pressing structure 100, further improves the flexibility and adaptability of the copper die pressing structure 100, so that the pressing range of the copper die pressing structure 100 on the workpiece 8 to be processed can be expanded, and the welding effect of the workpiece 8 to be processed can be better improved.

[0069] In some embodiments of the utility model, as shown in Figures 1-3 and Figure 5 As shown, the guide block assembly 1 has a sliding cavity 14 extending through the guide block assembly 1 along the third direction, and the sliding rail 6 is arranged in the sliding cavity 14. By sliding the sliding rail 6 in the sliding cavity 14, the movement of the guide block assembly 1 along the third direction on the sliding rail 6 can be facilitated, which is simple in structure and convenient to operate, can reduce the operation difficulty of the operator in adjusting the pre-pressing position, and further shorten the preparation time and improve the production efficiency.

[0070] In some embodiments of the utility model, as shown in Figures 1-3 and Figure 5 As shown, the copper die pressing structure 100 further comprises a clamping and limiting piece 7, which is arranged on the guide block assembly 1 and has one end extending into the sliding cavity 14 and abutting against the sliding rail 6. After the operator moves the guide block assembly 1 to the pre-pressing position, the clamping and limiting piece 7 can be adjusted so that the clamping and limiting piece 7 extends into the sliding cavity 14 and abuts against and presses the sliding rail 6, thereby the friction between the clamping and limiting piece 7 and the sliding rail 6 can be enhanced, the guide block assembly 1 can be tightly locked on the sliding rail 6, the movement of the guide block assembly 1 on the sliding rail 6 during welding can be avoided, and the pressing effect can be affected, thereby the welding defects such as virtual welding and miswelding of the workpiece 8 to be processed can be avoided, the penetration and width of the welding position of the workpiece 8 to be processed can be ensured to meet the welding requirements, and the welding efficiency and quality can be improved.

[0071] In some embodiments of the utility model, as shown in Figures 1-3 and Figure 5 As shown, the guide block assembly 1 is provided with a second threaded hole 134, and the clamping and limiting piece 7 comprises a clamping bolt 71 and a clamping nut 72, the clamping bolt 71 is arranged in the second threaded hole 134, and the clamping nut 72 is arranged on the clamping bolt 71 and located on the side of the second threaded hole 134 away from the sliding cavity 14.
