Description

[0001] This application is a divisional application of the application filed on October 27, 2023, with application number 202311401841.9 and invention title "A Welding Robot for Mold Production". Technical Field

[0002] This invention relates to the field of industrial robot technology, and in particular to a mold production welding robot. Background Technology

[0003] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines widely used in industrial fields. They possess a certain degree of automation and can perform various industrial processing and manufacturing functions based on their own power and control capabilities. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals. Compared with traditional industrial equipment, industrial robots have many advantages, such as ease of use, high level of intelligence, high production efficiency and safety, ease of management, and significant economic benefits. This allows them to operate in high-risk environments. With the continuous development of welding automation technology, more and more automatic welding robots are being used to weld workpieces in existing welding processes. In industrial manufacturing, manual welding is inefficient and produces inconsistent welding results when welding molds and welded connectors. Therefore, there is a particular need for a mold production welding robot.

[0004] However, existing welding robots require the conveying device to wait for the welding to be completed before conveying the mold again, which affects the welding efficiency. Moreover, the mold needs to be positioned during welding, and when different mold shapes need to be switched, the mold needs to be re-erected and the machine needs to be adjusted, which consumes a lot of manpower. Furthermore, the adjustment process also causes waste of materials for the workpiece to be welded and the welding connectors.

[0005] To address the aforementioned issues, a search revealed a patent with publication number CN107962321B disclosing a welding robot production line. The patent describes a system comprising six sequentially arranged robotic welding devices. Each device includes a rotating frame, an external shaft motor, and a connecting rod. A rotating frame is positioned to the right of the external shaft motor. A first rotating fixture is mounted on the upper left surface of the rotating frame, and a second rotating fixture is mounted on the upper right surface. A coolant is located on the back of the left end of the rotating frame, and a robot control cabinet is positioned to the right of the coolant. A welding torch grinder is mounted on the front surface of the robot control cabinet. The first and second rotating fixtures are mounted on the rotating frame, and the welding process is achieved through two rotating... The fixture secures the welding material, and a coolant is installed on the machine body. The coolant has multiple pipes inside, and the pipes are filled with condensate. The condensate is used as a medium to dissipate the heat generated during machine operation, reducing the frequency of machine maintenance and bringing convenience to the user. Although the heat generated during operation can be dissipated through condensate, the conveyor still needs to wait when welding the same welding point, and the mold needs to be re-erected and the machine adjusted when switching to different shaped molds.

[0006] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 The present invention provides a mold production welding robot: including a support platform 1 and a telescopic mechanism 3. A first button 2 is installed on one side of the surface of the support platform 1, the telescopic mechanism 3 is provided on one side of the surface of the support platform 1, a welding robotic arm 4 is installed on one side of the surface of the support platform 1, a first support frame 5 is connected to one side of the surface of the telescopic mechanism 3, a clamping mechanism 6 is provided on one side of the surface of the first support frame 5, a second support frame 7 is connected to one side of the surface of the first support frame 5, and a conveying mechanism 8 is provided on one side of the surface of the second support frame 7. The telescopic mechanism 3 includes an oil tank 301, a hydraulic cylinder 302, an oil pump 303, a directional valve 304, a hydraulic rod 305, an oil pipe 306, and a connecting block 307. The oil tank 301 is located inside the support platform 1. A hydraulic cylinder 302 is connected to one side of the support platform 1. An oil pump 303 and a directional valve 304 are also located inside the support platform 1. A hydraulic rod 305 and an oil pipe 306 are connected to one side of the hydraulic cylinder 302. The other end of the hydraulic rod 305 is connected to the connecting block 307. Through the arrangement of the oil tank 301, hydraulic cylinder 302, oil pump 303, directional valve 304, hydraulic rod 305, oil pipe 306, and connecting block 307, during use, pressing the first button... Pressing button 2 activates the oil pump 303, causing it to draw hydraulic oil from the oil tank 301. The pump then delivers the hydraulic oil to the directional valve 304 under high pressure. The directional valve 304 controls the hydraulic oil to flow into one end of the hydraulic cylinder 302, causing a change in the hydraulic pressure within the cylinder. This changes the extension and retraction of the hydraulic rod 305, which in turn moves the connecting block 307. The connecting block 307 then moves the first support frame 5, thus achieving the purpose of receiving the mold and transporting it to the welding robot arm 4 for welding. During welding, the hydraulic rod 305 moves another set of first support frames 5 to receive the mold, thereby achieving alternating mold transport for welding and improving work efficiency.

[0022] Furthermore, the welding robotic arm 4 is provided in two sets, the first support frame 5 is provided in two sets, and the oil pump 303 is electrically connected to the first button 2. Through the arrangement of the welding robotic arm 4 and the first support frame 5, the two sets of first support frames 5 can alternately transport the mold during use, so that the two sets of welding robotic arms 4 can weld the mold, avoiding the problem that the conveying mechanism 8 needs to stop and wait during welding, thus avoiding the problem of low work efficiency.

[0023] Furthermore, the oil pump 303 is connected to the oil tank 301 through the oil pipe 306, and the oil pump 303 is connected to the reversing valve 304 through the oil pipe 306. With the oil pump 303 in use, the oil pump 303 can provide power for the delivery of hydraulic oil, thereby providing power for the movement of the hydraulic rod 305.

[0024] Furthermore, the directional valve 304 is connected to the oil tank 301 via the oil pipe 306, and the directional valve 304 is connected to the hydraulic cylinder 302 via the oil pipe 306. With the setting of the directional valve 304, in use, the directional valve 304 connects the two ends of the hydraulic cylinder 302. During operation, the directional valve 304 can switch the hydraulic oil to be delivered to the port of the hydraulic cylinder 302 as needed, thereby controlling the direction of movement of the hydraulic rod 305.

[0025] Furthermore, the clamping mechanism 6 includes a support block 601, a clamping plate 602, a mounting groove 603, a cylinder 604, a limiting groove 605, a spring 606, a slider 607, and a sensor head 608. The support block 601 is connected to one side of the surface of the first support frame 5, and the clamping plate 602 is also connected to one side of the surface of the first support frame 5. The mounting groove 603 is formed on one side of the surface of the support block 601, and the cylinder 604 is installed inside the mounting groove 603. The limiting groove 605 is formed on one side of the surface of the clamping plate 602, and the spring 606 is installed inside the limiting groove 605. One end of the spring 606 is connected to the slider 607, and the other end of the slider 607 is connected to the sensor head 608. The clamping mechanism 6, through the support block 601, clamping plate 602, and mounting groove 603, allows for the connection of the cylinder 604 to the sensor head 608. The cylinder 604, limiting groove 605, spring 606, slider 607, and sensor head 608 are configured as follows: In operation, first button 2 is pressed, energizing cylinder 604. When the mold reaches a certain area, cylinder 604 extends and retracts, causing clamping plate 602 to move. Clamping plate 602 then moves spring 606, which in turn moves slider 607. Slider 607 then moves sensor head 608. When sensor head 608 touches the mold, the mold blocks its movement, and sensor head 608 blocks slider 607, causing slider 607 to compress spring 606 and retract. When clamping plate 602 reaches the appropriate position, cylinder 604 stops. At this point, multiple springs... 606, slider 607, and sensor head 608 surround the mold to clamp it. At the same time, sensor head 608 can sense the accurate position of the mold and transmit the position information to welding robot arm 4, so that welding robot arm 4 can position the mold during welding, improve the welding accuracy, and accurately position molds of different shapes, avoiding the need to re-set up the mold and adjust the machine when switching to different shapes of molds, thereby reducing work efficiency.

[0026] Furthermore, the cylinder 604 is electrically connected to the first button 2. One end of the cylinder 604 is connected to the support block 601, and the other end of the cylinder 604 is connected to the clamping plate 602. With the setting of the cylinder 604, when in use, the cylinder 604 can extend and retract after being energized, thereby driving the clamping plate 602 to extend and retract, thus providing power for the movement of the clamping plate 602.

[0027] Furthermore, the other end of the spring 606 is connected to the clamping plate 602, and the other end of the slider 607 passes through the limiting groove 605. Due to the setting of the spring 606, when in use, the spring 606 contracts when squeezed. When the squeezing force disappears, the spring 606 performs a reset movement due to its own characteristics, thereby driving the slider 607 to reset.

[0028] Furthermore, the conveying mechanism 8 includes a second button 801, a through hole 802, a protective shell 803, a motor 804, a rotating shaft 805, a bearing 806, a rolling roller 807, and a conveyor belt 808. The second button 801 is mounted on one side of the surface of the second support frame 7. A through hole 802 is opened on one side of the surface of the second support frame 7. A protective shell 803 is connected to one side of the surface of the second support frame 7. A motor 804 is housed inside the protective shell 803. A rotating shaft 805 is connected to one side of the surface of the motor 804. A rolling roller 807 is connected to the other end of the rotating shaft 805. A bearing 806 is connected to one side of the surface of the rotating shaft 805. 06. A conveyor belt 808 is connected to one side of the surface of the rolling roller 807. Through the arrangement of the second button 801, through hole 802, protective shell 803, motor 804, rotating shaft 805, bearing 806, rolling roller 807 and conveyor belt 808, in use, first press the second button 801. At this time, the second button 801 controls the motor 804 to start, so the motor 804 drives the rotating shaft 805 to rotate, the rotating shaft 805 drives the rolling roller 807 to rotate, so the rolling roller 807 drives the tensioned conveyor belt 808 to rotate, so that the conveyor belt 808 drives the mold to move, thereby achieving the effect of conveying the mold.

[0029] Furthermore, the second button 801 is electrically connected to the motor 804, and the bearing 806 is disposed in the through hole 802. Inside, the bearing 806 matches the size of the through hole 802. With the setting of the bearing 806, the bearing 806 can provide support for the rotating shaft 805 during use, while the bearing 806 does not hinder the rotation of the rotating shaft 805.

[0030] Working principle: A mold production welding robot, first press the first button 2 and the second button. 801. At this time, the second button 801 controls the motor 804 to start, which in turn drives the rotating shaft 805 to rotate. The rotating shaft 805 drives the rolling roller 807 to rotate, which in turn drives the tensioned conveyor belt 808 to rotate. This causes the conveyor belt 808 to move the mold, thus achieving the effect of conveying the mold. When the mold is conveyed to a certain area, the cylinder 604 begins to extend or retract, which in turn drives the clamping plate 602 to move. The clamping plate 602 drives the spring 606 to move, which in turn drives the slider 607 to move. The slider 607 drives the sensor head 608 to move. When the sensor head 608... When sensor 608 touches the mold, the mold blocks the movement of sensor 608, and sensor 608 blocks the movement of slider 607, causing slider 607 to compress spring 606. When clamping plate 602 moves to the appropriate position, cylinder 604 stops. At this time, multiple sets of springs 606, slider 607, and sensor 608 surround the mold, thus clamping the mold. Simultaneously, sensor 608 can sense the accurate position of the mold and transmit the position information to welding robot arm 4, thereby facilitating the positioning of the mold by welding robot arm 4 during welding and improving welding accuracy. At this time, oil pump 303 starts, thus... 303 draws hydraulic oil from tank 301, and then pump 303 delivers the hydraulic oil to the directional valve under high pressure. Inside 304, the reversing valve 304 controls the hydraulic oil input to one end of the hydraulic cylinder 302, thereby changing the hydraulic pressure in the hydraulic cylinder 302, which in turn controls the hydraulic rod 305 to extend and retract. The hydraulic rod 305 drives the connecting block 307 to move, and the connecting block 307 drives the first support frame 5 to move, thereby achieving the purpose of picking up the mold and transporting it to the welding robot arm 4 for welding. During welding, the hydraulic rod 305 drives another set of first support frames 5 to move and pick up the mold, thereby achieving the effect of alternating mold transportation for welding. This avoids the need for the conveying mechanism 8 to stop and wait during welding, which would lead to low work efficiency. This completes a mold production welding robot.
