Description

A quick-change industrial robot workstation for aluminum profile extrusion dies Technical Field

[0001] This invention belongs to the field of aluminum profile manufacturing technology, specifically relating to an industrial robot workstation for quick changing of aluminum profile extrusion dies. Background Technology

[0002] Aluminum profile extrusion dies are specialized tools used for extruding aluminum profiles. In aluminum profile production, molten aluminum is injected into the die cavity under high pressure through an extruder. After cooling, it forms profiles with specific cross-sectional shapes (such as door and window frames, radiators, etc.). Traditional extrusion production lines require machine shutdown, disassembly of the old die, cleaning, installation of the new die, and debugging and calibration when changing dies, which can take up to several hours. The rapid changeover industrial robot workstation achieves rapid die changeover through robotic technology, covering various forms such as fixed arms, AGVs, and robotic arms. Among them, the AGV industrial robot is the core, integrating end effectors (such as hooking / pushing mechanisms), positioning sensors (laser SLAM or visual recognition), and communication modules (linked with the extruder control system). It can automatically transport dies from the die library to the extruder station for changeover within the workshop, replacing manual handling and reducing die changeover time to the minute level. This solves the problem of insufficient flexibility of traditional fixed robots and is especially suitable for large dies or multi-station extrusion production lines.

[0003] Traditional AGV industrial robots are limited by fixed physical baffles and lack lateral constraints on mold movement. This can cause the mold to deviate due to inertia during the movement of the guide rollers, making it impossible to ensure accurate and stable docking with the extruder. The fixed limiting structure of traditional AGV industrial robots is also difficult to adjust flexibly, making it impossible to adapt to molds of different sizes and respond quickly to frequent mold change requirements, resulting in uneven distribution of clamping force on the mold. After mold change, the mold is stored on top of the AGV industrial robot. Since the AGV industrial robot does not effectively limit the mold on the infeed and outfeed sides, the mold may shift or even fall off the guide rollers during the transfer process, posing a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide an industrial robot workstation for rapid changing of aluminum profile extrusion dies. It can measure the die size in real time using a laser rangefinder sensor, driving the accommodating chamber to apply adaptive lateral constraints from both sides via double-cone limiting wheels. This allows for matching dies of different sizes, meeting the needs of high-frequency die-changing production, and suppressing inertial offset of the die during movement, ensuring precise docking with the extruder. The rotating accommodating chamber causes two baffles to simultaneously flip to the die's inlet / outlet side, forming a four-way limiting system with the inductive limiting plate and limiting wheels. This ensures the die's horizontal position during transport, eliminating the risk of die slippage or falling, and ensuring the docking accuracy of subsequent dies.

[0005] The technical solution adopted in this invention is as follows: An industrial robot workstation for quick replacement of aluminum profile extrusion dies includes two accommodating compartments set on the top of an AGV die-changing trolley. The accommodating compartments measure the distance of the die in real time through a laser measurement and control component and drive themselves to make displacement, in order to adapt to and constrain dies of different sizes. The accommodating compartments form symmetrical clamping of the die in the lateral direction through axially arranged limiting wheels, and limit the degree of freedom of the die based on rolling friction, in order to ensure the accuracy and stability of its displacement process. The accommodating compartments control themselves to rotate around the central axis to a predetermined angle through a servo motor, and control the baffle plate to move to the side of the die, in order to construct a four-way positioning constraint on the die.

[0006] The top of the AGV mold changing trolley is symmetrically and slidingly equipped with a mold hooking mechanism for controlling the displacement of the mold. Guide roller groups are symmetrically fixed on both sides of each mold hooking mechanism. A baffle is fixedly provided on the outside of the guide roller group. The top two ends of the baffle extend outward to form a support plate. A sliding groove is opened on the support plate along its own length direction.

[0007] An inductive limit plate is fixedly connected to the top end of the guide roller assembly. A PLC controller and a time delay relay, which are electrically connected to each other, are fixedly installed on the top of the AGV mold changing trolley. A contact switch is fixedly provided in the middle of the inductive limit plate and is electrically connected to the PLC controller. The PLC controller is also electrically connected to the two servo motors.

[0008] A sliding arm is slidably fitted inside the sliding groove, and the two sliding arms are fixedly connected by a connecting plate. A support plate is fixedly connected to the top of one end of the sliding arm. The accommodating chamber is rotatably disposed between the two support plates, and an mounting plate is fixedly connected to the outer wall of one of the support plates for mounting the laser measurement and control component.

[0009] A servo electric cylinder is fixedly installed on the outer wall of the baffle, and its output end is connected to the connecting plate. The servo electric cylinder receives the control signal of the laser measurement and control component through the wireless gateway to drive the connecting plate to move. The sliding arm forms a triangular stable structure with the support plate through the top inclined reinforcing plate.

[0010] The laser measurement and control component includes a laser rangefinder and a second PLC controller. The laser rangefinder measures the distance to the mold by emitting a pulsed laser beam, and the second PLC controller synchronously controls the extension and retraction of the output end of the servo electric cylinder.

[0011] The accommodating compartment has a cuboid structure with a cavity, and one side is an open end. A jacket plate with a wedge-shaped parallel line structure is slidably fitted inside the accommodating compartment. Sliding grooves are provided on the top and bottom surfaces of the accommodating compartment for sliding connection of the jacket plate. The limiting wheel has a double cone structure and is arranged in a straight line inside the jacket plate. It is rotatably connected to the jacket plate through a pivot at the center. The jacket plate is elastically connected to the inner wall of the accommodating compartment through spring columns spaced apart on the outer wall.

[0012] The accommodating compartment has a horizontal plate on the side opposite to its opening end, and the two ends of the horizontal plate are fixedly connected to the two reinforcing plates respectively; an extrusion head is symmetrically fixedly connected to one side of the horizontal plate. The extrusion head is an L-shaped plate extending into the interior of the accommodating compartment. The end of the extrusion head is rounded and located outside the wedge-shaped surface of the jacket plate; a clearance opening is provided through the corresponding position at the bottom of the accommodating compartment for the extrusion head to pass through. The servo motor is fixedly installed on the side wall of the support plate, and its output end is connected to the corresponding accommodating compartment for transmission.

[0013] The second baffle is located on the outside of the accommodating compartment and above the horizontal plate. The outer wall of the accommodating compartment is respectively provided with a lead screw and a guide rod, and the second baffle is respectively threaded and sliding with the two.

[0014] The top of the accommodating compartment is provided with an auxiliary limiting component, which includes symmetrically arranged bases and vertical rods. The two bases are rotatably connected by a rotating shaft and a drag-reducing wheel. The two ends of the bottom of the base are respectively in sliding fit with the vertical rod, and the middle part is elastically connected to the accommodating compartment through a spring column. The maximum adjustable stroke of the base in the vertical direction is ≤5mm.

[0015] The technical effects achieved by this invention are as follows: This invention can measure the mold size in real time through a laser rangefinder sensor, drive the accommodating chamber to drive the double cone limiting wheels to apply adaptive lateral constraints from both sides, match molds of different sizes, meet the needs of high-frequency mold change production, and suppress the inertial offset of the mold during movement to ensure precise docking of the extruder; by rotating the accommodating chamber, the baffle plate 2 is simultaneously flipped to the mold inlet and outlet side, forming a four-way limiting together with the inductive limiting plate, limiting wheels, etc., and superimposed with the top auxiliary limiting component, to ensure the horizontal position of the mold during transfer, solve the hidden danger of mold slippage or falling, and ensure the docking accuracy of subsequent molds.

[0018] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0019] As shown in Figures 1-4, an industrial robot workstation for quick replacement of aluminum profile extrusion dies includes two accommodating compartments 3 set on the top of an AGV die-changing trolley 1. The top of the AGV die-changing trolley 1 is symmetrically and slidably equipped with a die-hooking mechanism 101 for controlling the displacement of the die 102. Guide roller groups 106 are symmetrically fixed on both sides of each die-hooking mechanism 101. A baffle 103 is fixed on the outer side of the guide roller group 106.

[0020] According to the above structure, the AGV mold changing trolley 1 is generally equipped with a navigation system, which combines laser SLAM algorithm to accurately locate the driving position and accuracy. The top mold hooking mechanism 101 generally includes a hook guide rail and drive chain assembly. Through chain transmission with rollers, the hook seat is driven to move laterally along the guide rail, so that the hook can hook and push the mold 102 to move on the guide roller group 106.

[0021] Example 1: Referring to Figures 1-5, the accommodating chamber 3 uses a laser measurement and control component to measure the distance of the mold 102 in real time and drive its own displacement to adapt to and constrain molds 102 of different sizes; the accommodating chamber 3 forms a symmetrical clamping of the mold 102 laterally through the limiting wheels 303 arranged along the axial direction, and restricts the degree of freedom of the mold 102 based on rolling friction to ensure the accuracy and stability of its displacement process; the top two ends of the baffle 103 extend outward to form a support plate 104, and the support plate 104 has a sliding groove 105 along its own length direction. A sliding arm 2 is slidably fitted in the sliding groove 105, and the two sliding arms 2 are fixedly connected by a connecting plate 201. A support plate 202 is fixedly connected to the top of one end of the sliding arm 2; the accommodating chamber 3 is rotatably set on the two Between the support plates 202, and with one of the support plates 202 having a mounting plate 203 fixedly connected to its outer wall for mounting the laser measurement and control component, a servo electric cylinder 204 is fixedly mounted on the outer wall of the baffle 103, the output end of which is connected to the connecting plate 201. The servo electric cylinder 204 receives the control signal of the laser measurement and control component through a wireless gateway to drive the connecting plate 201 to move. The sliding arm 2 forms a triangular stable structure with the support plate 202 through a top-tilted reinforcing plate 205. The laser measurement and control component includes a laser range sensor 206 and a PLC controller 207. The laser range sensor 206 measures the distance to the mold 102 by emitting a pulsed laser beam and synchronously controls the extension and retraction of the output end of the servo electric cylinder 204 through the PLC controller 207.

[0022] According to the above structure, before the mold 102 is guided into the guide roller group 106 by the mold hooking mechanism 101, the laser range sensor 206 installed on the mounting plate 203 emits a pulsed laser beam to measure the distance of the mold 102 in real time, and feeds the data back to the servo cylinder 204 through the wireless link established by the PLC controller 207 via the wireless gateway I / O port and antenna; after receiving the command, the servo cylinder 204 retracts its output end, pulling the connecting plate 201 to move along the sliding groove 105 towards the baffle 103; furthermore, during this process, the support plate 104 supports the sliding arm 2, and synchronously drives the support plate 202, mounting plate 203, laser range sensor 206, PLC controller 207 and the accommodating chamber 3 to move as a whole, so that the two accommodating chambers 3 on both sides move towards each other; the laser range sensor 206 continuously monitors its distance from the mold 102. Once the outer edge of the limiting wheel 303 is displaced to completely coincide with the contour line of the side wall of the mold 102, the sensor immediately feeds back the position signal to the PLC controller 207. The controller determines that the target position has been reached according to the preset algorithm and immediately interrupts the drive command of the servo cylinder 204, so that the accommodating chamber 3 is locked at the precise position. Furthermore, at this time, the limiting wheel 303 can maintain contact with the side wall of the mold 102 to ensure the stability of rolling contact during the subsequent mold hooking process. Subsequently, the mold hooking mechanism 101 pulls the mold 102 into the guide roller group 106. The accommodating chamber 3 implements lateral constraint through the rolling contact between the double conical limiting wheel 303 and the side wall of the mold 102, reducing frictional resistance and suppressing deviation. The reinforcing plate 205 enhances the rigid connection between the sliding arm 2 and the support plate 202 to ensure the stability of the system.

[0023] The working principle of this invention is as follows: In this stage, relying on the real-time feedback of the laser rangefinder 206, the servo electric cylinder 204 is driven to link the accommodating chamber 3 to achieve dynamic centering; the double conical limit wheel 303 provides adaptive lateral constraint through rolling contact, ensuring the linear motion accuracy of the mold 102 under low friction conditions, and is supplemented by a reinforced structure to maintain the rigidity of the system.

[0024] Example 2: Referring to Figures 2-4, 6, and 8, the accommodating chamber 3 is controlled by a servo motor 308 to rotate around its central axis to a predetermined angle, controlling the baffle 4 to move to the side of the mold 102 to construct a four-way positioning constraint on the mold 102. The accommodating chamber 3 has a cuboid structure with a cavity, with one side being an open end. A sleeve plate 301 with a wedge-shaped parallel line structure is slidably fitted inside the accommodating chamber 3. Sliding grooves 302 are provided on the top and bottom surfaces of the accommodating chamber 3 for sliding connection of the sleeve plate 301. The sleeve plate 301 is elastically connected to the inner wall of the accommodating chamber 3 through spring pillars 304 spaced apart on the outer wall. An inductive limit plate 107 is fixedly connected to the top of the end of the guide roller group 106. A PLC controller 108 and a time delay relay 109, which are electrically connected to each other, are fixedly installed on the top of the AGV mold changing trolley 1. A connection is fixedly provided in the middle of the inductive limit plate 107. A touch switch is electrically connected to a PLC controller 108, which is also electrically connected to two servo motors 308. The limit wheel 303 has a double cone structure and is arranged in a straight line inside the jacket plate 301. It is rotatably connected to the jacket plate 301 through a rotating shaft at the center. The accommodating chamber 3 has a horizontal plate 307 on the side opposite to its opening end. The two ends of the horizontal plate 307 are fixedly connected to two reinforcing plates 205 respectively. A pressing head 306 is symmetrically fixedly connected to one side of the horizontal plate 307. The pressing head 306 is an L-shaped plate extending into the accommodating chamber 3. The end of the pressing head 306 is rounded and located outside the wedge-shaped surface of the jacket plate 301. A clearance opening 305 is provided through the corresponding position at the bottom of the accommodating chamber 3 for the pressing head 306 to pass through. The servo motor 308 is fixedly installed on the side wall of the support plate 202, and its output end is connected to the corresponding accommodating chamber 3.

[0025] According to the above structure, when the mold-hooking mechanism 101 pushes the mold 102 to the end of the guide roller group 106 and it is in contact with the inductive limiting plate 107, the contact switch immediately triggers a signal to the PLC controller 108. The PLC controller 108 synchronously starts two servo motors 308, driving the accommodating chamber 3 to rotate 90° around the central axis, so that the limiting wheel 303 faces the ground. Because the horizontal plate 307 is rigidly fixed to the reinforcing plate 205, its position remains unchanged, while the extrusion head 306 has already pressed against the jacket plate 301 before rotation to maintain the spring column 304 in an extended state. Furthermore, during the rotation, the jacket plate 301 disengages from the extrusion. The head 306 is constrained and slides along the sliding groove 302 under the contraction force of the spring column 304, driving the limit wheel 303 to retract into the accommodating chamber 3. The limit wheel 303 with the double cone structure effectively reduces interference with the side wall of the mold 102, while the avoidance opening 305 avoids mechanical conflicts on the rotation path. At the same time, the time delay relay 109 starts timing. After the preset transfer time ends, the PLC controller 108 instructs the servo motor 308 to rotate and reset, and the extrusion head 306 presses the jacket plate 301 again, so that the limit wheel 303 returns to the contact with the side wall of the mold 102, and rebuilds the lateral constraint for the subsequent removal operation.

[0026] The working principle of this invention is as follows: This stage starts with induction triggering, and the servo motor 308 drives the accommodating chamber 3 to rotate to realize the limit mode switching; the limit wheel 303 extension mechanism dominated by spring preload, combined with the drag reduction characteristics of the double conical surface design, ensures that the rotation process is smooth and without jamming, and automatically resets under delay control to complete the constraint state transformation during the transfer of mold 102.

[0027] Example 3: Referring to Figures 2 and 5-7, baffle 2 4 is located on the outside of the accommodating chamber 3 and above the horizontal plate 307. The outer wall of the accommodating chamber 3 is respectively provided with a lead screw 402 and a fixed guide rod 401, and baffle 2 4 is respectively threaded and slidingly engaged with the two. An auxiliary limiting component is provided at the top of the accommodating chamber 3. The component includes a symmetrically arranged base 403 and a vertical rod 405. The two bases 403 are rotatably connected by a rotating shaft and a drag-reducing wheel 404. The two ends of the bottom of the base 403 are respectively in sliding engagement with the vertical rod 405. The middle part is elastically connected to the accommodating chamber 3 through a spring column 2 406. The maximum adjustable stroke of the base 403 in the vertical direction is ≤5mm.

[0028] Based on the above structure, for different batches or commonly used specifications of molds 102, the operator can manually adjust the lead screw 402 to drive the baffle 2 4 to move axially along the guide rod 401 to adapt to the limiting requirements of molds 102 of different sizes. After the accommodating chamber 3 rotates into place, the originally vertical baffle 2 4 turns into a horizontal position, working together with the inductive limiting plate 107 to form the front and rear limiting of the mold 102; at the same time, the auxiliary limiting components at the top of the two baffles 103 face the mold 102, so that the drag reducing wheel 404 is close to the mold 102. 02 The side wall replaces the accommodating chamber 3 to bear the left and right constraints; furthermore, the base 403 of the auxiliary limiting component slides under the guidance of the vertical rod 405 (stroke ≤ 5mm), and the spring column 406 provides elastic buffer, which can not only ensure that the drag reducing wheel 404 can offset possible movement jamming through extension and retraction during the process of rotating with the accommodating chamber 3 and contacting the mold 102, but also limit the lateral offset of the mold 102 within the docking tolerance range. The baffle 4 and the auxiliary limiting component work together to ensure the stability of the mold 102 during the transfer process.

[0029] The working principle of this invention is as follows: In this stage, the limit mechanism is flexibly adapted through manual / automatic mixed adjustment; after rotation, the baffle 2 4 and the auxiliary limit component respectively bear the longitudinal and lateral constraints, and combined with the micro-motion compensation mechanism of spring buffer, it is ensured that the mold 102 is controlled throughout the transfer process, and the lateral offset is strictly controlled within the process allowable range.

[0030] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
