Detailed implementation manners

[0032] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure detailed in the appended claims.

[0033] Please refer to Figure 1 、 2 Figures 10 - 13. In an embodiment of the present invention, an automatic welding device for a stainless steel honeycomb core includes: a frame 600, at the bottom and both ends of which are respectively provided with an electric control unit, a guide rail mechanism, and a finished product discharge port; a feeding unit 100 installed at any one end of the guide rail mechanism; a displacement unit 500 installed at one end of the frame 600 close to the guide rail mechanism; and a rolling and forming unit 200 and a welding unit 300 adjacently installed on the guide rail mechanism, and the guide rail mechanism drives the rolling and forming unit 200 and the welding unit 300 to reciprocate; the electric control unit controls the feeding unit 100 and the rolling and forming unit 200 to supply raw materials and roll and supply the raw materials into single - piece honeycomb cores, and controls the displacement unit 500 to drive the previous single - piece honeycomb core to be close to the next single - piece honeycomb core; the welding unit 300 is used to weld the two single - piece honeycomb cores that are close together by the displacement unit 500.

[0034] Specifically, the electric control unit includes an electric control box and a relay and a controller installed in the electric control box. The controller is electrically connected to the feeding unit 100, the guide rail mechanism, the rolling and forming unit 200, the welding unit 300, and the displacement unit 500 respectively through a plurality of relays to control the operation of each unit or mechanism. The feeding unit 100 includes a feeding rack, a coil mounting mechanism and a discharging mechanism 102 installed on the feeding rack. The raw material is clamped on the coil mounting mechanism, and the leading end of the raw material passes through the discharging mechanism and is connected to the rolling and forming unit 200. The coil mounting mechanism includes a coil cylinder, which is installed on the feeding rack through a coil shaft. One end of the coil shaft is drivingly connected to a coil motor. The discharging mechanism 102 includes a plurality of coil rollers installed on the mounting rack with relative displacement. The leading end of the raw material is wound around the coil rollers reciprocally and then connected to the rolling and forming unit.

[0035] Automatic welding process of stainless steel honeycomb core: The controller supplies power to the feeding unit 100, the guide rail mechanism, the rolling and forming unit, the welding unit and the displacement unit. The coiling motor of the feeding unit drives the coiling cylinder to rotate, releasing the raw material clamped on the coiling cylinder. The raw material is the stainless steel honeycomb panel coil 101. The head end of the stainless steel honeycomb panel coil 101 bypasses the coiling roller and passes through the rolling and forming unit 200. At the same time, the guide rail mechanism drives the rolling and forming unit 200 to move towards the feeding unit. The stainless steel honeycomb panel coil 101 passing through the rolling and forming unit 200 is pressed into the first single-piece honeycomb core A. After that, the first single-piece honeycomb core A is manually moved towards the finished product discharge port by a displacement, and the displacement is the honeycomb width of the stainless steel honeycomb core. The guide rail mechanism drives the rolling and forming unit 200 to reset and press the second single-piece honeycomb core A. After the second single-piece honeycomb core A is pressed, the guide rail mechanism drives the rolling and forming unit to reset, and the first single-piece honeycomb core A is manually driven to be closely attached to the second single-piece honeycomb core A. The guide rail mechanism drives the welding unit to move towards the feeding unit. During the movement, the first single-piece honeycomb core A and the second single-piece honeycomb core A that are closely attached are clamped, and the joint is welded to form a part of a version of the stainless steel honeycomb core. After that, the displacement unit replaces the manual operation to perform the displacement and close attachment of the single-piece honeycomb core A. Until a version of the stainless steel honeycomb core is completed. Since the stainless steel honeycomb core already has a honeycomb structure, the displacement unit can insert or extract the honeycomb, and push the honeycomb to move accordingly after inserting the honeycomb. There is no need for manual movement of the third, fourth and the Nth single-piece honeycomb core A. It can be automatically completed by the displacement unit. For the other single-piece honeycomb cores A in a version of the stainless steel honeycomb core except the first and second single-piece honeycomb cores A, the displacement unit performs the close attachment and displacement. After a version of the stainless steel honeycomb core B is welded, it is manually removed from the finished product discharge port and transported away.

[0036] It should be noted that during the movement of the guide rail mechanism, it can drive the rolling and forming unit and the welding unit to move independently or synchronously, and perform pressing and welding separately or synchronously. Its specific working mode can be configured according to the actual application scenario.

[0037] In addition, the guide rail mechanism includes a frame body, a guide rail, a guiding lead screw, a sliding plate and a lead screw motor. The guide rail is arranged at one end of the frame 600 away from the finished product discharge port through the frame body. The guiding lead screw is installed on the frame body through bearings and is parallel to the guide rail. The lead screw motor is installed at one end of the guiding lead screw. The rolling and forming unit and the welding unit are installed on the sliding plate that is in threaded cooperation with the guiding lead screw. The lead screw motor drives the rolling and forming unit and the welding unit to reciprocate through the guiding lead screw and the sliding plate.

[0038] Therefore, the automatic welding equipment for the stainless steel honeycomb core replaces manual operation for the feeding, rolling and forming, and welding processes of the stainless steel honeycomb core coil; realizes automation, improves work efficiency, and saves labor.

[0039] Furthermore, as Figure 7 shown, a shearing unit 400 is installed on one side of the frame near the discharging end of the feeding unit, and the shearing unit 400 is used to shear the raw material end of a single honeycomb core.

[0040] The shearing unit includes scissors, a lifting assembly and an opening / closing driving member. The scissors and the opening / closing driving member are installed at the telescopic end of the lifting assembly. The lifting assembly drives the scissors to approach or move away from the raw material end of a single honeycomb core, and the opening / closing driving member drives the scissors to open and close.

[0041] In actual application, the scissors can be industrial scissors 401, the lifting assembly can be an electric telescopic rod 404 or a lifting cylinder. The opening / closing driving member is a forward / backward motor, and the forward / backward motor is installed at the output end of the electric telescopic rod 404 or the lifting cylinder through a movable block 403; a guide rod 405 installed in parallel on the frame guides the lifting of the movable block 403. The output shaft of the forward / backward motor is connected with a lead screw 402, a nut is threadedly installed on the lead screw 402, two connecting rods are welded on both sides of the nut, and the two connecting rods are respectively connected to the ends of the handles of the industrial scissors 401. The electric telescopic rod 404 drives the industrial scissors 401 to approach or move away from the raw material end of a single honeycomb core, and the rotation of the forward / backward motor drives the nut to move on the output shaft of the forward / backward motor. The nut drives the industrial scissors 401 to open and close through the connecting rods to shear the connection between the raw material end of a single honeycomb core and the raw material. The provided shearing unit further improves the automation degree of the equipment.

The mounting seat is movably installed on a guide rail mechanism, two mutually cooperating rolling and forming gears 202 are installed on the mounting seat through bearings, the forming motor 201 is drivingly connected to one of the rolling and forming gears 202, and the forming motor drives the rolling and forming gears to press the raw material passing through between the two rolling and forming gears 202 to form a single honeycomb core.

[0043] Please refer to Figure 5 、 6 , in another embodiment of the present invention, the welding unit includes a support frame, feeding pressure wheels 301 and a laser welding head 302. The support frame is movably installed on a guide rail mechanism, two feeding pressure wheels 301 are installed on the support frame through bearings, a welding station is left between the two feeding pressure wheels 301, the laser welding head 302 is installed on the support frame, and the focus point of the laser welding head is focused on the welding station. The two feeding pressure wheels 301 are engaged with the formed single honeycomb core and the welded honeycomb core single piece to clamp two honeycomb cores, and the laser welding head welds the joint of the two honeycomb cores.

[0044] In the application of the present invention, in a preferred embodiment, any one of the feeding pressure wheels 301 is installed on the support frame through a lifting adjustment assembly, and the lifting adjustment assembly is used to adjust the gap between the two feeding pressure wheels.

[0045] The lifting adjustment assembly includes a lifting hydraulic rod. The feeding pressure wheel 301 at the top of the welding station is installed at one end of the lifting hydraulic rod through a connecting plate, and the other end of the lifting hydraulic rod is installed on the connecting plate in the plane where the welding station is located. The feeding pressure wheel at the top of the welding station is adjusted by the lifting hydraulic rod to adjust the gap between the two feeding pressure wheels; in this way, honeycomb chip bodies with various different heights can be automatically welded by this device.

[0046] Please refer to Figure 8 、 9 In another embodiment of the present invention, the shifting unit includes a pin member, a first power member, and a second power member. The two first power members are relatively installed at the top of one end of the frame close to the guide rail mechanism. The second power member is connected to the output ends of the two first power members. The pin member is installed at the output end of the second power member. The first power member drives the pin member and the second power member to lift, and the second power member drives the pin member to move.

[0047] The first power member uses a power cylinder 501, and the second power member uses a power motor 502. The two power cylinders 501 are relatively installed at the top of one end of the frame close to the guide rail mechanism. The telescopic ends of the two power cylinders 501 are connected through a connecting pipe. A transfer platform is provided below the connecting pipe. A plurality of parallel transmission shafts are slidably installed on the transfer platform.

[0048] During the working process of the shifting unit, it is necessary to shift the single-piece honeycomb core after the second single-piece honeycomb core of a version of stainless steel honeycomb core for convenient welding. After welding, the welded single-piece honeycomb core is pressed tightly against the subsequent single-piece honeycomb core. The shifting and pressing-tightening processes are realized by the power cylinder 501 driving the pin to insert into the honeycomb of the stainless steel honeycomb core and then the power motor 502 driving the pin to move.

[0049] Furthermore, the first power member or the second power member uses a power cylinder 501 or a power motor 502.

At the same time, the guide rail mechanism drives the rolling forming unit 200 to move towards the feeding unit. The stainless steel honeycomb panel coil 101 passing through the rolling forming unit 200 is pressed into the first single-piece honeycomb core A. Then, the operator moves the first single-piece honeycomb core A by a displacement towards the finished product outlet. The said displacement is the honeycomb width of the stainless steel honeycomb core. The guide rail mechanism drives the rolling forming unit 200 to reset and press the second single-piece honeycomb core A. After the second single-piece honeycomb core A is pressed, the guide rail mechanism drives the rolling forming unit to reset, and the operator drives the first single-piece honeycomb core A to be close to the second single-piece honeycomb core A. The guide rail mechanism drives the welding unit to move towards the feeding unit. During the movement, the first single-piece honeycomb core A and the second single-piece honeycomb core A that are close to each other are clamped, and the joint is welded to form a part of one version of the stainless steel honeycomb core. After that, the shifting unit replaces the operator to perform the shifting and close fitting of the single-piece honeycomb core A until one version of the stainless steel honeycomb core is completed.
