[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0043] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0044] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0045] During the welding process, it is often necessary to cut the welded product to remove the waste material left near the weld location, thereby forming the product's desired shape and improving the overall appearance. During welding and cutting, waste slag is generated, much of which falls onto the product and contaminates it.

[0046] To solve the above technical problems, the present invention provides a welding and cutting system for welding and cutting products. To facilitate the description of the technical solution of the present invention, the product is a battery as an example for explanation.

[0047] That is, the welding and cutting system in the present invention is used to perform full welding on the semi-finished products after electric welding of the battery body and the top cover in battery production, thereby realizing fully enclosed welding of the battery body and the top cover, and to perform cutting between the full weld seam and the spot weld after full welding to remove waste materials such as skirts.

[0048] Please combine Figures 1 to 3 、 Figure 5 and Figure 7The welding and cutting system provided by the present invention will now be described. The welding and cutting system includes a base 1, a carrying portion 11, a first driving device 20, a cover 2, a fixing member 3, a welding device 30, and a cutting device 40. The carrying portion 11 is provided on the base 1 and is used to carry the product. The first driving device 20 is provided on the base 1. The first driving device 20 can place the cover 2 and the fixing member 3 on the product. The cover 2 covers the product and exposes the waste material on the product. The fixing member 3 is spaced apart from the cover 2 to form a gap 100. The fixing member 3 can fix the waste material. The welding device 30 is provided on the base 1. The welding device 30 can weld the product through the gap 100. The cutting device 40 is provided on the base 1. The cutting device 40 can separate the waste material from the product through the gap 100.

[0049] In summary, the implementation of the embodiments of the present invention has the following beneficial effects: The welding and cutting system of the above-described scheme, in addition to providing excellent welding and cutting performance, can also prevent or mitigate contamination of the product by waste slag generated during welding and cutting. Specifically, the welding and cutting system comprises a base 1, a support portion 11 disposed on the base 1, a first drive device 20, a welding device 30, and a cutting device 40. The support portion 11 is used to support the product to prevent it from moving during subsequent welding and cutting processes. Furthermore, the first drive device 20 is capable of placing the cover 2 and the fixing member 3 on the product. The cover 2 covers the product and exposes the waste material on the product. This allows the cover 2 to cover a large portion of the product, reducing the area of the product exposed to waste slag. The fixing member 3 is spaced apart from the cover 2 to form a gap 100. This allows the product to be exposed only at the position to be processed, i.e., at the gap 100. This facilitates subsequent processing positioning while preventing excessive exposure of the product, thereby reducing the area of the product exposed to waste slag. Furthermore, the fixing member 3 can fix the waste material. Thus, the position accuracy of the product can be further improved by the fixing member 3, thereby ensuring the accuracy of subsequent processing.

[0050] In one embodiment, please combine Figures 5 to 7, the welding and cutting system also includes a first jig 10 and a first clamping mechanism 12. The carrying portion 11 is provided on the first jig 10. In this embodiment, the carrying portion 11 has a carrying groove, and the product can be partially accommodated in the carrying groove and the waste material can be fitted with the first jig 10. The first clamping mechanism 12 is provided on the first jig 10, and can drive the fixing member 3 to fix the waste material to the first jig 10. In this way, by driving the fixing member 3, the connection stability between the product and the first jig 10 can be further improved, and the product position accuracy during subsequent welding and cutting processes can be ensured. In addition, in some embodiments, the welding and cutting system may not be provided with a fixing member 3, and the waste material can be directly fixed to the first jig 10 through the first clamping mechanism 12. In this embodiment, in addition to being used to reduce the contact area between the product and the waste residue, the fixing member 3 can also reduce the risk of the waste residue falling into the first jig 10, thereby avoiding the first jig 10 being contaminated by a large amount of waste residue, which is inconvenient to clean and affects the subsequent carrying of the product. In this embodiment, as Figure 13 As shown, since the top cover 5 provided on the battery body 4 is relatively flat, the cover 2 and the fixing member 3 are both plate-shaped structures to better fit the top cover 5. It is understood that in other embodiments, the cover 2 and the fixing member 3 can also have other structures to match the position of the product to be placed.

[0051] In one embodiment, please combine Figure 7 and Figure 13 The side of the cover 2 facing the product is aligned with the product. This ensures that the cover 2 is fully adhered to the product and prevents waste from contaminating the product through the gap between the cover 2 and the product. During the welding and cutting processes, the cover 2 can be secured by a fixing structure, which can be a downward pressure structure, to prevent the cover 2 from moving relative to the product during these processes. In some embodiments, when the vibration generated during the welding and cutting processes is minimal and there is an interlocking structure between the cover 2 and the product, the fixing structure can be omitted to reduce the overall cost of the welding and cutting system.

[0052] In one embodiment, Figure 7, the first clamping mechanism 12 includes a first driving component 121 and a first clamping member 122. The first driving component 121 can drive the first clamping member 122 to move toward the fixed member 3 along the first direction, and can drive the first clamping member 122 to move in a direction deviating from the first direction, so that the first clamping member 122 is projected onto the fixed member 3 along the first direction and is located outside the fixed member 3. That is, the first driving component 121 can drive the first clamping member 122 to rotate and move linearly. The first driving component 121 includes a linear motor and a rotary motor connected to each other. In this way, the first driving component 121 drives the first clamping member 122 to rotate to avoid the cover 2, making it convenient for the first driving device 20 to place the cover 2 and the fixed member 3 on the product. Thereafter, the first driving component 121 drives the first clamping member 122 to rotate and reset, and then drives the first clamping member 122 to move linearly along the first direction to drive the fixed member 3 to fix the waste on the first fixture 10. In this embodiment, the first direction is parallel to Figure 7 The direction indicated by the arrow X.

[0053] In one embodiment, please refer to Figure 7 The first jig 10 is provided with a second drive assembly 13 to separate the product from the waste. In this embodiment, the second drive assembly 13 is located on the first jig 10 and below the product to enable lifting and driving of the product. The second drive assembly 13 is provided with a first detection unit (not shown) for detecting the driving force exerted by the second drive assembly 13 on the product. The cooperation between the first detection unit and the second drive assembly 13 allows detection of whether the product and waste are completely separated. Specifically, when the product and waste are completely separated, the driving force is within a preset range. However, when the product and waste are not completely separated, i.e., a connection exists between the product and waste, and the product cannot move due to the fixing member 3, the driving force exceeds the preset range. The first detection unit then issues a signal indicating that the product and waste are not completely separated, allowing the cutting process to be repeated accordingly. Furthermore, when multiple first detection units are used, the driving force values at different locations can be used to locate the connection between the product and waste, saving time during re-cutting and improving overall processing efficiency. In this embodiment, the first detection unit is a pressure sensor.

[0054] In one embodiment, please refer to Figure 7, a first dust extraction mechanism 14 is provided on the first fixture 10. The first dust extraction mechanism 14 has a dust extraction chamber. The dust extraction chamber is located below the gap 100, and the dust extraction chamber is connected to the first vacuum device (not shown). In this way, the waste residue can fall into the dust extraction chamber. At the same time, after the first vacuum device is turned on, the absorption capacity of the waste residue is further improved, and the waste residue is further prevented from contaminating the product. In this embodiment, the first dust extraction mechanism 14 includes two relatively arranged box body structures, and the dust extraction chamber is formed in the box body structure. The box body structure is slidably connected to the first fixture 10 so that it can be separated from the first fixture 10 after accommodating a certain amount of waste residue to dump the waste residue.

[0055] In one embodiment, Figure 5 As shown, the welding and cutting system also includes a conveyor device 50. The first jig 10 is mounted on the conveyor device 50 and is driven to move by the conveyor device 50. The movement path of the first jig 10 includes at least a welding and cutting station. That is, the welding and cutting processes are completed at the same station, reducing the size of the waste slag generation area. The welding device 30 and the cutting device 40 are each mounted on a first mounting frame 31 via multiple drive units. The first mounting frame 31 is mounted across the conveyor device 50 to suspend the welding device 30 and the cutting device 40. These multiple drive units include at least a linear motor and a rotary motor to achieve linear and rotary motion of the welding device 30 and the cutting device 40 to accommodate different processing paths. The first vacuum device can be connected to the dust extraction chamber when the first jig 10 moves to the welding and cutting station. This prevents the dust extraction chamber and the first vacuum device from being permanently connected via a flexible pipeline, preventing the flexible pipeline from interfering with the movement of the first jig 10 and saving the cost of flexible pipeline loss.

[0056] In one embodiment, Figure 6 As shown, the first dust extraction mechanism 14 is provided with a socket 15. Socket 15 is connected to the dust extraction chamber. The first vacuum device is provided with an interface that can be plugged into and connected to the socket 15 when the first jig 10 is moved to the welding and cutting station. This allows the dust extraction chamber and the first vacuum device to be plugged into and connected to each other through the socket 15 and the interface when the welding and cutting station is in operation.

[0057] In one embodiment, Figure 6 As shown, the first vacuum device includes a third drive assembly, with an interface located therein. The third drive assembly is used to drive the interface to connect and connect with socket 15. Specifically, at the welding and cutting stations, the interface is extended to connect and connect with socket 15, thus preventing interference with the movement of the first jig 10. Furthermore, in some embodiments, the interface can be located in the movement path of the first jig 10, enabling connection and connection between the interface and socket 15 when the first jig 10 reaches the welding and cutting stations.

[0058] In one embodiment, Figure 6As shown, the socket 15 is provided with a sealing ring to clamp the interface and socket 15 when the interface and socket 15 are plugged in and connected, thereby enhancing the sealing between the interface and socket 15. Furthermore, the interface and socket 15 can be connected magnetically. This further improves the connection stability between the socket 15 and the interface through the magnetic connection when the interface and socket 15 are plugged in and connected.

[0059] In one embodiment, please combine Figure 1 、 Figure 2 and Figure 4 , the welding and cutting system also includes a loading device 60. The loading device 60 is provided on the base 1. The loading device 60 includes a fourth drive assembly 61 and a positioning mechanism 62. The fourth drive assembly 61 can place the product on the positioning mechanism 62 and can remove the product from the positioning mechanism 62 and place it on the carrying portion 11. In this way, the product can be initially positioned by the setting of the positioning mechanism 62, ensuring the position accuracy of the product and the fourth drive assembly 61 when the fourth drive assembly 61 is removed from the positioning mechanism 62, thereby ensuring the accuracy of the fourth drive assembly 61 in placing the product on the carrying portion 11, and avoiding damage to the product and the carrying portion 11 due to low positioning accuracy when the fourth drive assembly 61 directly places the product on the carrying portion 11. In this embodiment, the positioning mechanism 62 is provided on the base 1, and the fourth drive assembly 61 is provided on the base 1 through the second mounting bracket 611.

[0060] In one embodiment, the loading device 60 further includes a positioning member (not shown), which can be positioned with a positioning structure located on the product. Figure 13 As shown, the top cover 5 is provided with a positioning structure, and the positioning member can cooperate with the positioning structure to further ensure the position accuracy of the product in the positioning mechanism 62. Figure 4 As shown, the loading device 60 further includes a second detection unit 63, which is used to detect the position accuracy of the product located in the positioning mechanism 62. The second detection unit 63 is a visual sensor that can accurately locate the product shape, further improving the position accuracy of the product in the positioning mechanism 62.

[0061] In one embodiment, Figure 4As shown, the positioning mechanism 62 includes a frame 621 and a plurality of clamping assemblies 622 arranged around the frame 621. The frame 621 is used to carry the product, and the clamping assemblies 622 can cooperate with each other to drive the product located on the frame 621 to a preset position and fix it. In this embodiment, the clamping assembly 622 includes a push plate and a linear motor. The linear motor can drive the push plate closer to or away from the product to achieve clamping or separation of the product. Furthermore, some of the push plates in the multiple clamping assemblies 622 can be fixed and play a role in positioning the product, while the remaining push plates can move linearly to drive the product to a fixed push plate and fix it. In order to reduce wear on the product, elastic members are also provided at the contact positions between the push plate and the frame 621 and the product.

[0062] In one embodiment, Figure 2 and Figure 3 As shown, the first drive device 20 can simultaneously place the cover 2 and the fixing member 3 on the product. This can improve the processing efficiency of the product and save the time of transporting the cover 2 and the fixing member 3. The first drive device 20 can also simultaneously retrieve the cover 2, the fixing member 3 and the waste after the product is separated from the waste. While the cover 2 and the fixing member 3 are reset, the waste is separated from the product. In this embodiment, Figure 7 As shown, the fixing member 3 is provided with an escape space 200. This escape space 200 allows waste material to be exposed, allowing it to contact the first drive device 20 and be driven away from the product by the first drive device 20. It is understood that in other embodiments, the waste material can also be magnetically attracted to the first drive device 20 to be driven by the first drive device 20. Furthermore, the first drive device 20 is mounted on the third mounting frame 21 and suspended above the conveying device 50 via multiple drive units. The multiple drive units enable both linear and rotational motion of the first drive device 20.

[0063] In one embodiment, Figure 2 As shown, the welding and cutting system further includes a containment structure 22. The first drive device 20 is capable of placing the cover member 2 and the fixing member 3 in the reset position and separating them from the waste material, allowing the waste material to fall into the containment structure 22. This allows for quick storage of the waste material and prevents it from interfering with the operation of other structures. In this embodiment, a movable containment structure 22, such as a trolley, can be placed below the reset position to facilitate transporting the containment structure 22 away from the reset position after the waste material fills the containment structure 22. The containment structure 22 can then be emptied in the dumping position, allowing it to be reused for waste storage.

[0064] In one embodiment, Figure 2 and Figures 8 to 12As shown, the welding and cutting system also includes a trimming device 70. The trimming device 70 is used to trim the cut surface a formed on the product. The trimming device 70 can remove burrs on the cut surface a to prevent the burrs from puncturing or affecting the assembly of subsequent structures.

[0065] In one embodiment, please combine Figure 11 and Figure 12 The trimming device 70 includes a first rolling surface 711 and a second rolling surface 721. The first rolling surface 711 can abut against one side of the cutting surface a and contact the product line. A first tangent point can be formed between the first rolling surface 711 and the cutting surface a, so that burrs on one side of the cutting surface a can be removed when rolling relative to the product. Furthermore, the second rolling surface 721 can abut against the other side of the cutting surface a and contact the product point. A second tangent point can be formed between the second rolling surface 721 and the cutting surface a, so that burrs on the other side of the cutting surface a can be removed when rolling relative to the product, thereby achieving the effect of removing burrs on the cutting surface a. The first normal line b passing through the first tangent point intersects with the second normal line c passing through the second tangent point, and the second normal line c passes through the first rolling surface 711. The first and second tangent points are the points of force applied to the product by the first rolling surface 711 and the second rolling surface 721, respectively. The intersection of the first normal line b and the second normal line c ensures that the forces acting on the product by the first and second rolling surfaces 711, 721 are coplanar, preventing twisting deformation of the cut surface a caused by the intersecting directions of the forces. Furthermore, the second normal line c passes through the first rolling surface 711, enabling the first and second rolling surfaces 711, 721 to clamp the product, ensuring that the first and second tangent points are always formed on both sides of the cut surface a during the trimming process, improving burr removal. Furthermore, the second rolling surface 721 is tilted relative to the first rolling surface 711 to avoid the remaining structure of the product.

[0066] In one embodiment, please combine Figure 9 、 Figure 11 and Figure 12The trimming device 70 includes a first roller 71 and a second roller 72. The first roller 71 includes a first circumferential wall. A first rolling surface 711 is formed on the first circumferential wall. The first rolling surface 711 can roll relative to the product along with the first roller 71. In this way, the first rolling surface 711 can be rigidly supported by the first roller 71, while ensuring the stability of the first rolling surface 711 rolling relative to the product. Furthermore, the second roller 72 includes a second circumferential wall 722. The second circumferential wall 722 is deflected away from the first roller 71 from one end of the second rolling surface 721, allowing the second rolling surface 721 to roll relative to the product along with the second roller 72. In this way, the second rolling surface 721 can be rigidly supported by the second roller 72, while ensuring the stability of the second rolling surface 721 rolling relative to the product. In addition, the second circumferential wall 722 can be kept away from the first roller 71 to prevent contact during transmission, which would affect the rolling relative to the product.

[0067] In one embodiment, please combine Figure 9 and Figure 11 The trimming device 70 also includes a first elastic mechanism 73. The first roller 71 and the second roller 72 are arranged on the first elastic mechanism 73. The first elastic mechanism 73 can generate a first elastic force, the direction of which is tangential to the first rolling surface 711 and passes through the second rolling surface 721. In this way, when the product is clamped between the first rolling surface 711 and the second rolling surface 721, the second rolling surface 721 can be driven, causing the first elastic mechanism 73 to generate the first elastic force and react on the second rolling surface 721, so that the second rolling surface 721 always elastically abuts against the product during the trimming process, ensuring the burr removal effect. At the same time, it prevents the product from being damaged by excessive impact when inserted between the first rolling surface 711 and the second rolling surface 721.

[0068] In one embodiment, please refer to Figure 9 and Figure 11 The first elastic mechanism 73 includes a first elastic component 731, a bracket 732, and a slider 733. The first roller 71 and the second roller 72 are mounted on the slider 733, which is slidably connected to the bracket 732. The first elastic component 731 is connected between the bracket 732 and the slider 733 to transmit the first elastic force to the first roller 71 and the second roller 72 through the slider 733. This sliding connection between the slider 733 and the bracket 732 ensures the directional accuracy of the first elastic force, thereby ensuring the contact accuracy between the first rolling surface 711 and the second rolling surface 721 and the product.

[0069] In one embodiment, please refer to Figure 9 and Figure 11The trimming device 70 also includes a first detection component 74 for detecting the magnitude of the first elastic force. In this way, the first detection component 74 can be set to prevent the first elastic force from being too large, which may cause damage to the product. At the same time, the range value of the first elastic force can be preset. When the first elastic force reaches the preset value, it can be prompted that the first rolling surface 711 and the second rolling surface 721 are in good contact with the product and the subsequent trimming process can be carried out. In this embodiment, the first detection component 74 includes a scale 741 and an indicator 742. The scale 741 is provided on the bracket 732. The indicator 742 is provided on the slider 733. The indicator 742 can move with the slider 733 to move relative to the scale 741 to display the magnitude of the first elastic force. It can be understood that in other embodiments, the first detection component 74 can also be a sensor to detect the magnitude of the first elastic force.

[0070] In one embodiment, please refer to Figure 9 and Figure 11 The trimming device 70 further includes a first driving mechanism 75. The first driving mechanism 75 is provided on the slider 733. The first roller 71 and the second roller 72 are connected to the first driving mechanism 75, and the first driving mechanism 75 is used to adjust the distance between the first roller 71 and the second roller 72. In this way, the distance between the first roller 71 and the second roller 72 can be adjusted by the setting of the first driving mechanism 75 to adapt to different cutting surface a sizes, so as to facilitate the insertion of products of different sizes between the first rolling surface 711 and the second rolling surface 721. In this embodiment, the first driving mechanism 75 includes two oppositely arranged clamping jaws, and the first roller 71 and the second roller 72 are rotatably connected to the two clamping jaws in a one-to-one correspondence. The two clamping jaws can move relative to each other to achieve the approach and separation of the first roller 71 and the second roller 72.

[0071] In one embodiment, please refer to Figure 9 and Figure 11The trimming device 70 also includes a second elastic component and a third elastic component. The second elastic component is provided in the first driving mechanism 75 and is capable of generating a second elastic force to drive the first roller 71 toward the second roller 72. The third elastic component is provided in the first driving mechanism 75 and is capable of generating a third elastic force to drive the second roller 72 toward the first roller 71. Specifically, the second elastic force can be generated when the first roller 71 contacts the product and reacts to the first rolling surface 711, causing the first rolling surface 711 to elastically abut the product. The third elastic force can be generated when the second roller 72 contacts the product and reacts to the second rolling surface 721, causing the second rolling surface 721 to elastically abut the product. This ensures that both the first rolling surface 711 and the second rolling surface 721 elastically abut the product, preventing the product from getting stuck when the gap 100 between the first rolling surface 711 and the second rolling surface 721 does not match the product size. For example, when there are large impurities between the first rolling surface 711 and the product and they cannot be removed by rolling of the first rolling surface 711, the first rolling surface 711 can pass through the impurities and further compress the second elastic component to avoid jamming.

[0072] In one embodiment, please refer to Figure 9 and Figure 11 The trimming device 70 further includes a second detection assembly 76 for detecting the distance between the first roller 71 and the second roller 72 so as to match the distance with the product size. Specifically, the second detection assembly 76 is provided on the two clamping jaws.

[0073] In one embodiment, please combine Figures 8 to 12 The trimming device 70 also includes a second drive mechanism 77. This second drive mechanism 77 is capable of driving the first roller 71 and the second roller 72 to move the product, causing the first rolling surface 711 and the second rolling surface 721 to roll relative to the product. The second drive mechanism 77 is mounted on the base 1 via a fourth mounting bracket 78. The second drive mechanism 77 is connected to the bracket 732 to enable linear or rotational movement of the bracket 732.

[0074] In one embodiment, Figure 2 and Figure 13As shown, the welding and cutting system also includes a second jig 80, a second clamping mechanism 81, and a fifth drive assembly 82. The fifth drive assembly 82 is capable of placing the product located on the carrying portion 11 on the second jig 80. The second clamping mechanism 81 is capable of clamping the product on the second jig 80 so that the trimming device 70 can trim the cutting surface a. In this way, the second clamping mechanism 81 can ensure the stability of the connection between the product and the second jig 80, thereby ensuring the stability of the position of the product during the trimming process. In this embodiment, the number of conveying devices 50 is two, and the first jig 10 and the second jig 80 are respectively arranged on different conveying devices 50. It can be understood that in other embodiments, the first jig 10 and the second jig 80 can also be arranged on the same conveying device 50.

[0075] In one embodiment, Figure 13 As shown, the second clamping mechanism 81 includes multiple sixth drive assemblies 811. Each sixth drive assembly 811 is arranged around the second jig 80. A second clamping member 812 is provided on each of the sixth drive assemblies 811. The sixth drive assemblies 811 are capable of driving the second clamping members 812 to swing. The swinging path of the second clamping members 812 has at least a first position and a second position. In the first position, each second clamping member 812 can enclose a placement space for the product and can clamp the product. In the second position, the second clamping members 812 can deviate from the placement space to avoid the trimming device 70. The trimming device 70 must ensure the product's position is stable during the trimming process. Therefore, the second clamping members 812 used to secure the product can interfere with the trimming operation of the trimming device 70. In this embodiment, the number and distribution of the second clamping members 812 should be increased to meet the minimum number required to secure the product to the second jig 80. In this way, when the trimming device 70 moves to a certain second clamping member 812, the second clamping member 812 deviates from the placement space to avoid the trimming device 70, while the other second clamping members 812 can still ensure the stability of the position between the product and the second fixture 80.

[0076] In one embodiment, Figure 2 and Figure 14 As shown, the welding and cutting system also includes a dust removal device 91, a detection device 92 and a feeding device 93. The dust removal device 91 is used to remove dust from the product after trimming to further clean the product. The dust removal device 91 includes multiple dust suction chambers to correspond to the products on the multiple second fixtures 80. The detection device 92 is used to detect the product after dust removal to detect whether the product is qualified. The detection device 92 can perform product appearance detection or product performance detection. The feeding device 93 is used to transfer qualified products to the next workstation and place unqualified products on the transmission component 94. The transmission component 94 is used to transfer unqualified products to unqualified workstations. As shown Figure 1 As shown, in this embodiment, the welding and cutting system also includes a shell 6 for protecting the internal structure of the welding and cutting system. The shell 6 is provided with multiple openings to facilitate product transfer between the loading device 60 and the unloading device 93 and other process positions.
