Description

[Technical field]

[0001] The invention relates to the field of automation equipment, in particular to an automatic welding machine for metal mesh baskets. [Background technology]

[0002] At present, most of the metal mesh baskets sold on the market are made of stainless steel, usually consisting of a mesh basket body and a reinforced metal frame welded to the top opening of the mesh basket body. First, the mesh sheet needs to be cut, and then the mesh sheet is placed in a stamping die for stamping to obtain a mesh basket body, and then the mesh basket body is manually taken out and the metal frame is inserted into the mesh basket body, and then manually welded, and finally manually deburred to form a qualified product. At present, most of the processing links of metal mesh baskets are handled independently, and each process requires manual operation, which seriously affects production efficiency. For example, patent number: CN202011385945.1 Metal mesh basket production line and method thereof, including a workpiece input positioning device, a first welding machine, a welding positioning device, a first manipulator, a deburring punch, a second manipulator, a second welding machine, a third manipulator, a shaping machine, a fourth manipulator, a workpiece output device and a fifth manipulator. The prior art provides a production line that can achieve continuous processing and reduce manual operations, but the production line has certain shortcomings. First, each process needs to be equipped with a robot, which makes the whole machine not compact enough, and too many robots also increase production costs and maintenance costs; second, the floor area of ​​the entire production line is too large, and only one device can be placed in the same area.

By setting a balancing ejector, when the forming platen is lifted up, it can balance the forming platen and will not cause the workpiece to be uneven. At the same time, the forming platen is lifted up, and the worker can observe whether the differential pressure of the workpiece is in place.

When the dividing cylinder is not started, the first paddle supports the metal frame. When the dividing cylinder is started, the metal frame is relatively stationary. While the first paddle rotates, the second paddle rotates. Since the thickness of the second paddle is equal to the thickness of the metal frame, when the first paddle is separated from the bottom of the current metal frame, the second paddle simultaneously cuts into the bottom of the relative position of the current metal frame.

[0042] See also Figure 1-11 , Figure 1-11The best embodiment of the disclosed metal basket automatic welding machine:

[0043] The metal mesh basket automatic welding machine includes a body 100, on which a first machine platform 101 and a second machine platform 102 are respectively arranged, a slideway 103 is arranged between the first machine platform 101 and the second machine platform 102, and a forming mechanism is arranged on the first machine platform 101. The slideway 103 is inclined downward toward the second machine platform 102, so that the blank formed after the forming mechanism punches the metal mesh can automatically slide off the slideway 103.

[0044] The forming mechanism can be a forming frame 201 and a mold. The forming frame 201 is placed on the first machine 101. The forming frame 201 is provided with a head plate and a tail plate. The four corners of the head plate and the tail plate are provided with guide columns 202. The movable guide plate 203 is sleeved on the guide column 202 and can move up and down along the guide column 202.

[0045] The mold is set between the movable guide plate 203 and the tail plate, and the power source can be set on the head plate and the movable guide plate 203. For example, the power source uses a hydraulic cylinder, which is fixed on the head plate. The hydraulic rod of the hydraulic cylinder passes through the head plate and is fixed on the movable guide plate 203.

[0046] The mold includes an upper mold and a lower mold. The upper mold is movably arranged on a movable guide plate 203, and the lower mold is movably arranged on a tail plate of a forming frame 201. The hydraulic cylinder pushes the movable guide plate 203 to close the upper mold toward the lower mold.

[0047] Exemplarily, the upper mold can be a fixed plate 204, a first forming plate 205 and a second forming plate 206. The fixed plate 204 is embedded in the movable guide plate 203 through a T-block and fixedly connected to the movable guide plate 203 with bolts. The fixed plate 204 and the first forming plate 205 are connected by four forming columns 209. The first forming plate 205 and the second forming plate 206 are fixedly connected by bolts. The first forming plate 205 and the second forming plate 206 are respectively provided with a first opening 207 and a second opening 208. In order to observe the stamping effect, a forming pressure plate 210 is provided above the first forming plate 205. The forming pressure plate 210 is connected to the fixed plate 204 by a forming spring 211. When stamping, the metal sheet will lift up the forming pressure plate 210. At the same time, in order to make the stamped blank have a flat bottom surface, the four corners of the forming platen 210 are provided with balancing pins 212, and the balancing pins 212 are at a certain distance from the fixed plate 204. When stamping, the metal sheet will push up the forming platen 210, and the spring will be compressed. When the balancing pins 212 collide with the fixed plate 204, the spring will no longer be compressed. At this time, the upper mold continues to move downward, and the metal sheet is formed into a flat bottom under the action of the forming platen 210. The first forming plate 205 is provided with a pressing strip 213, which is connected to the first forming plate 205 through a pressing spring 214, and the pressing strip 213 is arranged on the left side of the second forming plate 206.

[0048] The fixed plate 204 and the movable guide plate 203 are movably connected via T-slots and T-blocks. When the mold needs to be replaced, the replacement can be completed by simply withdrawing the upper mold. By setting a balancing ejector pin 212, when the forming platen 210 is lifted up, it can balance the forming platen 210 and will not cause the bottom of the workpiece to be uneven. At the same time, the forming platen 210 is lifted up, and the worker can observe whether the differential pressure of the workpiece is in place.

[0049] Exemplarily, the lower mold can be a pad 301, a bottom plate 302, a mold core 303 and a molding three-plate 304. The mold core 303 is fixedly set on the bottom plate 302. The molding three-plate 304 is connected to the bottom plate 302 by a downward pressure spring 305. A third opening 306 is opened on the molding three-plate 304. After the mold core 303 passes through the third opening 306, the second opening 208 and the first opening 207 in sequence, it is surrounded by the molding pressure plate 210, the molding first plate 205, the molding second plate 206 and the molding three-plate 304 to form a processing cavity. The four corners of the bottom plate 302 are provided with positioning blocks 307, and the bottom plate 302 is provided with a horizontal pressing block 308. The horizontal pressing block 308 is set on the left side of the mold core 303.

[0050] The mold core 303, the forming plate 210, the first forming plate 205, the second forming plate 206 and the third forming plate 304 enclose a processing cavity. When the second forming plate 206 and the third forming plate 304 are pressed down, the horizontal pressing block 308 and the pressing strip 213 press the metal mesh, thereby forming a shearing force, and the metal mesh is sheared while stamping, thereby improving production efficiency. The four in-place blocks 307 play a role of limiting, preventing the upper die from over-stamping and affecting the quality of the metal mesh basket.

[0051] Exemplarily, a pushing device is also provided at the rear of the mold, and the pushing device includes a pushing frame, a pushing cylinder, a toggle motor and a toggle rod. The pushing cylinder and the toggle motor are arranged on the pushing frame, a rack is arranged on the piston rod of the pushing cylinder, a moving block meshing with the rack is arranged on the toggle motor, the rack is arranged between the moving block and the toggle motor, and the toggle rod is arranged on the rotating shaft 408 of the toggle motor. When in use, the moving block is adjusted to a suitable position along the rack direction, and then the moving block and the toggle motor are clamped with the rack by bolts. After the mold punches the metal mesh to form the metal mesh basket blank, the toggle motor is started, thereby driving the toggle rod to rotate, thereby pushing the metal mesh blank to the slideway 103, so that the metal mesh basket blank passes through the slideway 103 and slides down automatically.

[0052] On the second machine 102, a material unloading station, a transfer station 104, a welding station and a discharging station are sequentially arranged. A suspension frame 402 is arranged on the left side of the second machine 102. A driving mechanism is provided in the middle of the suspension frame 402 to push the slot of the metal mesh basket. The material unloading station and the transfer station 104 are arranged above the suspension frame 402. A metal frame 98 material unloading mechanism is arranged on the material unloading station. The driving mechanism is arranged below the suspension frame 402. The blank can be pushed to the material unloading station and the transfer station 104 in sequence through the driving mechanism.

[0053] Exemplarily, the unloading mechanism of the metal frame 98 includes an unloading rack 401 and a material distribution driving mechanism, the unloading rack 401 is provided with an unloading port 403, the material distribution driving mechanism is arranged on both sides of the unloading port 403, the unloading port 403 is provided with 4 inner walls, each inner wall is provided with 2 unloading strips 404, and a total of 8 unloading strips 404 are enclosed to form an unloading channel, and the metal frame 98 is placed along the unloading channel and conflicts with the material distribution driving mechanism. When the metal frame 98 is almost used up, the worker only needs to add the metal frame 98 to the unloading channel again, which is simple to work.

[0054] Exemplarily, the driving mechanism includes a slide plate 501, a first feed block 502 and a second feed block 503 arranged on the second machine 102, the slide plate 501 is arranged below the suspension frame 402, a slide rail is arranged on the slide plate 501, the first feed block 502 and the second feed block 503 move back and forth on the slide rail through the slider, the first feed block 502 and the second feed block 503 are both pivotally connected to the slider, and a avoidance surface 504 is arranged on the right side of the first feed block 502 and the second feed block 503, so that the first feed block 502 and the second feed block 503 can rotate on the slider, and feeding fixing blocks 505 are arranged at both ends of the slide plate 501, the tail end of the first feeding cylinder is pivotally connected to the feeding fixing block 505, the piston rod is pivotally connected to the first feeding block 502, the tail end of the second feeding cylinder is pivotally connected to the feeding fixing block 505, and the piston rod is pivotally connected to the second feeding block 503.

[0055] After the workpiece slides down to the suspension frame 402 through the slideway 103, the first feeding cylinder is started to push the first feeding block 502 to move toward the workpiece along the slide rail through the slider. When the first feeding block 502 collides with the workpiece, the workpiece is a metal mesh basket, and the basket body has four sides, namely, the front side, the rear side, the left side and the right side. Since the first feeding block 502 has an avoidance surface 504, the first feeding block 502 rotates in the direction of the avoidance surface 504, thereby sending the first feeding block 502 to the left side of the workpiece, and then the first feeding cylinder is reset. At this time, the first feeding cylinder is reset. Block 502 presses against the left side of the workpiece, thereby pushing the workpiece to the bottom of the unloading mechanism of the metal frame 98. At this time, the second feeding block 503 is located below the unloading mechanism of the metal frame 98. When the workpiece arrives, since the second feeding block 503 has an avoidance surface 504, the second feeding block 503 rotates toward the avoidance surface 504, thereby moving the second feeding block 503 to the right inner wall of the workpiece. When the metal frame 98 falls onto the workpiece, the second feeding cylinder starts, pushing the second feeding block 503 to drive the workpiece to move along the slide rail toward the transfer station 104.

[0056] The material distribution driving mechanism provided in the embodiment of the present application can be a material distribution gas rod 405 and a paddle, which are both arranged on the unloading rack 401, and the tail of the material distribution gas rod 405 is pivoted by a fixed block 406, and two shaft seats 407 are arranged on the side near the unloading port 403, and the two shaft seats 407 are arranged in parallel. The rotating shaft 408 passes through the unloading rack 401 and is sleeved on the shaft seat 407, and the rotating shaft 408 is rotatably arranged on the shaft seat 407. The lower end of the rotating shaft 408 is provided with a first paddle 409 and a second paddle 410, and the first paddle 409 and the second paddle 410 are installed in a superimposed manner, and the other end is provided with a connecting piece 411, and a linkage rod 412 is pivoted between the connecting piece 411 and the connecting piece 411, and the piston rod of the material distribution gas rod 405 is pivoted to one end of the linkage rod 412 through a linkage block 413.

[0057] When in use, the material distribution cylinder is started, and the piston rod of the material distribution cylinder drives the linkage block 413 to push forward. Since the connecting piece 411, the linkage rod 412 and the linkage block 413 are all pivotally connected, when the piston rod is pushed forward, the connecting piece 411, the linkage rod 412 and the linkage block 413 are simultaneously linked to drive the rotating shaft 408 to rotate, thereby driving the first paddle 409 and the second paddle 410 to rotate. The second paddle 410 is arranged below the first paddle 409. In this embodiment, the first paddle 409 and the second paddle 410 are arranged at an angle of 50°. When the material distribution cylinder is not started, the first paddle 409 supports the metal frame 98. When the material distribution cylinder is started, the metal frame 98 is relatively stationary. When the first paddle 409 rotates, the second paddle 410 rotates. Since the thickness of the first paddle 409 is equal to the thickness of the metal frame 98, when the first paddle 409 is separated from the bottom of the current metal frame 98, the second paddle 410 simultaneously cuts into the relative position of the current metal frame 98. When the first paddle 409 is completely separated from the current metal frame 98, the current metal frame 98 automatically falls onto the second paddle 410, and then the material dividing cylinder is reset, the second paddle 410 is separated from the bottom of the baffle metal frame 98, and the first paddle 409 is inserted into the bottom of the next metal frame 98 at the same time. When the second paddle 410 is completely separated from the bottom of the current metal frame 98, the current metal frame 98 automatically falls onto the workpiece, and the first paddle 409 is completely inserted into the bottom of the next metal frame 98 to form a support. At this time, the rotation angle of the first paddle 409 and the second paddle 410 is 50°. When the material dividing cylinder completes one action, only one metal frame 98 falls, and the placement of the metal frames 98 is automatically completed, reducing labor costs.

[0058] The transfer mechanism provided in the embodiment of the present application can be a transfer frame 701 and a mechanical arm arranged on the transfer frame 701.

The first mechanical arm 703 and the second mechanical arm 704 are arranged on the transfer track 702. The first mechanical arm 703 and the second mechanical arm 704 achieve synchronous movement by setting a traction rod 705. A driving motor 706 and a screw 707 are arranged behind the first mechanical arm 703 and the second mechanical arm 704. The first mechanical arm 703 is provided with a driving block 708 meshed with the screw 707.

The inner wall of the rotating wheel is provided with an internal thread meshed with the screw 707. The driving motor 706 is fixedly connected to the screw 707. When the driving motor 706 rotates forward, the driving motor 706 rotates to drive the screw 707 to rotate. The thread of the screw 707 is meshed with the rotating wheel thread of the driving block 708, so that the driving block 708 drives the first mechanical arm 703 to move forward along the transfer track 702. Since a traction rod 705 is provided between the first mechanical arm 703 and the second mechanical arm 704, the first mechanical arm 703 brings the second mechanical arm 704 to move synchronously when it moves. When the driving motor 706 flips, the first mechanical arm 703 and the second mechanical arm 704 move backward synchronously.

[0059] The first mechanical arm 703 and the second mechanical arm 704 provided in the embodiment of the present application can be a suspension frame 801 and a hanging catch 802.

The hanging catch 802 is fixedly connected to the stabilizing plate 804. The stabilizing plate 804 is provided with an exit cylinder 805 and a plurality of limit ejectors 806. The limit ejectors 806 are arranged on the four vertices of the stabilizing plate 804. The connecting rod of the cylinder 805 passes through the stabilizing plate 804 and is connected to the top plate 807. The stabilizing plate 804 is provided with four side edges, each of which is provided with a clamping finger 808. The distance between the front and rear clamping fingers 808 is slightly smaller than the width of the workpiece, and the distance between the left and right clamping fingers 808 is slightly smaller than the length of the workpiece. Because the metal mesh basket has a certain flexibility, when the metal mesh basket is sent to the transfer station 104 by the second feeding cylinder, the driving motor 706 rotates forward, driving the first mechanical arm 703 and the second mechanical arm 704 to move forward. When the arm 703 moves to the top of the transfer station 104, the second robot arm 704 moves to the top of the welding station, the propulsion cylinder is started, and the lifting claw 802 moves downward. At this time, the four clamping fingers 808 press down the four side walls corresponding to the metal mesh basket, and then the propulsion cylinder is reset, so as to clamp the metal mesh baskets of the transfer station 104 and the welding station, and then the driving motor 706 is reversed, the first robot arm 703 and the second robot arm 704 move backward, the first robot arm 703 transports the metal mesh basket to the welding station, and the second robot arm 704 The metal mesh basket is transported to the unloading station. When the first robot arm 703 transports the metal mesh basket to the top of the welding station, the second robot arm 704 transports the metal mesh basket to the top of the unloading station, and then the propulsion cylinder is started to move the hanging grab 802 downward. The metal mesh basket on the first robot arm 703 is placed on the welding station, and the metal mesh basket on the second robot arm 704 is placed on the unloading station. Then the propulsion cylinder 803 is reset, and the exit cylinder 805 is started at the same time. The workpiece is pushed out of the four fingers 808 through the top plate 807 to complete the placement process.

[0060] The welding mechanism provided in the embodiment of the present application can be a support 601 for placing a workpiece. Two welding cylinders 602 are provided on the four sides of the support 601, and a total of eight welding cylinders 602 are provided. A welding head 603 is provided on the piston rod of the welding cylinder 602, and the piston rod of the welding cylinder 602 moves toward the support 601.

[0061] This welding method adopts butt welding, so the support 601 and the welding head 603 are both made of metal, and the bottom of the metal mesh basket is in contact with the support 601. When welding is required, the support 601 and the welding head 603 are energized. At this time, the metal mesh basket is energized, the welding cylinder 602 is driven, and the welding head 603 applies pressure to the metal frame 98, so that the metal mesh basket and the metal frame 98 are welded.

[0062] The working steps of the present invention are as follows:

[0063] First, the feeder pushes the metal mesh into the mold, and the upper mold moves downward to punch out the metal mesh basket blank.

The first feeding cylinder is started to push the first feeding block 502 to the left side of the metal mesh basket blank. Then, the first feeding cylinder is reset to push the metal mesh basket blank to the bottom of the unloading mechanism of the metal frame 98, and then the material dividing cylinder The piston rod of the material distribution cylinder drives the linkage block 413 to move forward, so that the first paddle 409 and the second paddle 410 rotate and reset once, so that one metal frame 98 falls off, and then the second feeding cylinder is started, pushing the second feeding block 503 to drive the metal basket blank to move to the transfer station 104, and then the driving motor 706 rotates forward, driving the first mechanical arm 703 and the second mechanical arm 704 to move forward. When the first mechanical arm 703 moves to the top of the transfer station 104, The propulsion cylinder is started to move the hanging catch 802 downward, and the metal mesh basket blank is clamped by the four clamping fingers 808, and then the motor 706 is driven to reverse, and the first mechanical arm 703 and the second mechanical arm 704 move backward. The first mechanical arm 703 transports the metal mesh basket to the welding station. When the first mechanical arm 703 transports the metal mesh basket to the top of the welding station, the propulsion cylinder is started to move the hanging catch 802 downward, and the metal mesh basket on the first mechanical arm 703 is placed on the support 601, and then the push cylinder is started. The air inlet cylinder 803 is reset, and the air outlet cylinder 805 is started at the same time, and the metal mesh basket blank is pushed out from the four clamping fingers 808 through the top plate 807. Then the welding cylinder 602 is driven, and the welding head 603 applies pressure to the metal frame 98, so that the metal mesh basket and the metal frame 98 are welded. Finally, the driving motor 706 rotates forward, driving the first robot arm 703 and the second robot arm 704 to move forward. The second robot arm 704 repeats the above grabbing action to transport the metal mesh basket blank to the unloading station.
