DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-12The present invention provides a technical solution: an automatic slot welding device for a middle spacer, mainly composed of an equipment cabinet 1, and a first material unloading rack 2, a second material unloading rack 3, a multifunctional processing module 4, an upper laser welder 5, and a lower laser welder 6 installed on the equipment cabinet 1, wherein the multifunctional processing module 4 is located between the first material unloading rack 2 and the second material unloading rack 3, the first material unloading rack 2 can convey the A material belt constituting the middle spacer to the multifunctional processing module 4, and similarly, the second material unloading rack 3 can convey the B material belt constituting the middle spacer to the multifunctional processing module 4. The processing module 4 can punch and cut the material strip A at the beginning, and then convey the punched material strip A. During the conveying process, the multifunctional processing module 4 can assemble the material A and the material B together. After assembly, when passing through the positions of the upper laser welder 5 and the lower laser welder 6, the upper laser welder 5 and the lower laser welder 6 can respectively weld the welding positions of the upper and lower parts of the middle septum assembly. After welding, the finished middle septum is obtained, and then the finished product is separated from the material strip by secondary stamping. Specifically; The multifunctional processing module 4 is composed of a first material belt feeding mechanism 41, a second material belt feeding mechanism 42, a first punching die 43, an inserting mechanism 44, a pre-pressing die 45, a welding position pressing die 46, a welding point pressing die 47, and a second punching die 48. The first material belt feeding mechanism 41 can convey the A material and the middle partition assembly. The first material belt feeding mechanism 41 and the second material belt feeding mechanism 42 have the same structure. The second material belt feeding mechanism 42 can separate the B material from the material belt and assemble the B material on the outside of the A material through the inserting mechanism 44 to form the middle partition assembly. After assembly, The assembly passes through the pre-pressing module 45, the welding position pressing module 46, and the welding point pressing module 47 in sequence. The pre-pressing module 45 is used to perform preliminary pressing on the welding position of the middle septum before it enters the welding area to ensure the flatness and close contact of the welding surface. The welding position pressing module 46 presses the welding position of the middle septum during welding to maintain the stability and contact quality during welding. The welding point pressing module 47 is used to flatten the burrs that may be generated after welding to improve the smoothness and overall quality of the welding part. Then, the assembly passes through the second punching die 48, which punches the finished product from the material strip. The first material belt feeding mechanism 41 is mainly composed of a conveying track 411 and a conveying driving device 412, wherein the conveyed metal material belt 413 will be laid flat inside the conveying track 411, that is, the conveying track 411 serves as a support and guide structure for the metal material belt 413 to ensure that it can move smoothly. The conveying driving device 412 is installed on the upper part of the conveying track 411, and a plurality of reserved holes 4131 are provided on both sides of the metal material belt 413. These reserved holes 4131 are evenly distributed in a linear shape and are used to cooperate with the conveying driving device 412 to achieve the pulling and positioning of the metal material belt. The specific technical scheme is as follows: The conveying drive device 412 is the core component of the feeding mechanism, including an active pulling module 4121 and a driven pulling module 4122, which are connected by a linkage rod 4123 to achieve synchronous action; The active pulling module 4121 is mainly composed of a first linear guide rail 41211, a first slide 41212, a first lifting drive cylinder 41216, a first lifting seat 41214 and an active pulling rod 41215. The first linear guide rail 41211 is installed on the upper part of the conveying track 411 to provide a sliding track for the first slide 41212. The first slide 41212 slides on the first linear guide rail 41211 to achieve horizontal movement; When the active pulling module 4121 is working, the first lifting drive cylinder 41216 is started, and its telescopic end is connected to the first lifting seat 41214, driving the first lifting seat 41214 and the active pulling rod 41215 to descend synchronously. After descending, the active pulling rod 41215 will be inserted into a corresponding reserved hole 4131, and then the pulling drive cylinder 41213 will extend, pushing the first slide 41212 to slide on the first linear guide rail 41211. The sliding process In the process, combined with the engagement of the active pulling rod 41215 and the reserved hole 4131, the metal strip 413 can be driven to move as a whole, and the distance of each movement is fixed (a number of middle spacers are connected in series in the metal strip 413, and the distance of each movement is the width of a middle spacer). After the movement, the active pulling rod 41215 rises and disengages from the reserved hole 4131, and the first slide seat 41212 is reset, and the cycle is repeated in sequence to realize the pulling of the metal strip 413.

[0025] The driven pulling module 4122 is mainly composed of a second linear guide rail 41221, a second slide 41222, a second lifting drive cylinder 41223, a second lifting seat 41224 and a driven pulling rod 41225. The second linear guide rail 41221 is also installed on the upper part of the conveying track 411 to provide a sliding track for the second slide 41222; When the driven pulling module 4122 is working, the linkage rod 4123 is connected between the first slide 41212 and the second slide 41222. First, the second lifting drive cylinder 41223 pushes the second lifting seat 41224 and the driven pulling rod 41225 to move downward as a whole. Similarly, the driven pulling rod 41225 is inserted into a corresponding reserved hole 4131. Then, as the first slide 41212 mentioned above slides, the second slide is moved downward under the action of the linkage rod 4123. The seat 41222 will also slide accordingly, so that the active pulling module 4121 and the driven pulling module 4122 can pull the metal strip 413 synchronously (because the length of the metal strip 413 is very long, if there is only a single pulling point of the active pulling module 4121, the part of the metal strip 413 away from the pulling point will be easily bent, that is, during the conveying process of the entire metal strip 413, a certain section will bulge, causing damage to the metal strip 413); The insert mechanism 44 includes a base 4431, a slider 4432, a driving cylinder 4434 and other components. The base 4431 is the main part of the entire insert driving device, which provides a stable support platform. A guide groove 44311 with both ends open is provided inside the base 4431. This guide groove is used to guide the sliding of the slider 4432. In addition, a limit groove 44312 connected to the guide groove 44311 is also provided on the side of the base 4431. This limit groove is used to insert a limit pin 44313 to limit the sliding range of the slider 4432. The slider 4432 is a key component in the insert drive device, which is responsible for carrying the B material and sliding it. A limit groove 44325 is provided at the bottom end of the slider 4432, and this limit groove cooperates with the limit pin 44313 on the base 4431 to ensure that the slider 4432 does not deviate from the predetermined track during the sliding process. The top of the slider 4432 is respectively provided with a material receiving position 44321 and an insert baffle 44322. The material receiving position 44321 is used to receive the B material, and the insert baffle 44322 is used to push the B material into the designated position of the A material when the slider 4432 slides to the designated position. In addition, a slot 44324 is also provided at the top of the slider 4432 for installing the cylinder mounting seat 4435; The driving cylinder 4434 is the power source of the insert driving device. Its telescopic end is connected to the slider 4432 through the connecting piece 4438. A slot 2 44381 is provided at the bottom end of the connecting piece 4438, and a slot 1 44323 is provided at the end of the slider 4432. The two slots are engaged with each other to ensure that the telescopic end of the driving cylinder 4434 can firmly push the slider 4432 to slide. The cylinder mounting seat 4435 is connected to the slider 4432 through the slot 44324, and a pressing cylinder 4436 is installed at its end. The telescopic end of the pressing cylinder 4436 is against the slider 4432, and is used to press the B material against the slider 4432 before the slider 4432 slides to the specified position to prevent it from falling off during the sliding process. The outer protrusion of the cylinder mounting seat 4435 is also connected to an adjusting bolt 4437, and this adjusting bolt is located above the B material; When the insert mechanism 44 is working, when material A and material B are respectively conveyed to the designated positions (material B is located in the receiving position 44321), after receiving the materials, the pressing cylinder 4436 is shortened, and the pressing cylinder 4436, the cylinder mounting seat 4435, and the adjusting bolt 4437 are lowered as a whole by the reaction force, so that the bottom end of the adjusting bolt 4437 is pressed on the material B. Subsequently, the insert driving device 443 starts to work, driving the telescopic end of the cylinder 4434 to extend, pushing the slider 4432 to slide along the guide groove 44311. In the embodiment, the limit pin 44313 cooperates with the limit slot 44325 to ensure that the slider 4432 will not deviate from the predetermined track. When the slider 4432 slides to the specified position, the pressing cylinder 4436 extends. Relying on the reaction force, the pressing cylinder 4436, the cylinder mounting seat 4435, and the adjusting bolt 4437 rise as a whole, and the pressure of the adjusting bolt 4437 on the B material is released. Subsequently, the slider 4432 will push the B material into the specified position of the A material with the help of the insert baffle 44322, and then re-connect the material in the retreat position, and repeat the above process.
