Description

Technical Field

[0001] This invention relates to the field of aluminum-ammonia heat pipe feeding technology, and in particular to a partitioned multi-station loading and unloading platform. Background Technology

[0002] In the production and processing of aluminum-ammonia heat pipes, multi-station loading and unloading operations are required to facilitate the transfer between different processes. Existing technologies, such as the loading / unloading platform for a robotic workstation disclosed in CN209554224U, feature an upper and lower clamping fixture mounting plate that moves back and forth interactively. Another example is the reciprocating steel pipe loading / unloading platform disclosed in CN207107819U, which achieves reciprocating loading and unloading of steel pipes on a single component, reducing the equipment's footprint. Both of these methods use a single-layer pallet or fixed tray structure to carry materials. While these structures can accomplish basic material conveying, they have the following shortcomings in practical applications: Limited space utilization and operational efficiency: Existing equipment mostly adopts a single-layer tray design, and loading and unloading operations usually need to be performed in steps. That is, one tray can only enter the working area after the other tray has completed loading or unloading, making it impossible to achieve parallel and alternating loading and unloading operations. This serial working mode results in a lot of waiting time for the equipment, low overall space utilization, and seriously restricts the improvement of production cycle time.

[0003] Insufficient automation precision and adaptability: For aluminum ammonia heat pipes with model QR codes, existing devices lack in-situ scanning and identification, as well as proactive alignment functions during tray displacement. When the heat pipe shifts or becomes disorganized in the tray due to displacement inertia, the downstream robotic arm struggles to grasp it accurately. Especially during processing, the opening and closing of the holes at the ends of the aluminum ammonia heat pipe can change, and a single clamping structure cannot adjust in real time according to these changes. Furthermore, it cannot automatically adjust the clamping and positioning strategy based on the identified different model numbers, resulting in a high failure rate and poor compatibility in subsequent automated operations. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of the difficulty in preparing and conveying multi-specification aluminum ammonia heat pipes in the prior art, and to propose a partitioned multi-station loading and unloading platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A partitioned multi-station loading and unloading platform includes a movable platform, an upper loading tray and a lower loading tray for carrying aluminum-ammonia heat pipes, and further includes: The feeding section is mounted on a mobile machine platform and includes an annular chain located at the front of the mobile machine platform. A first traction bracket and a second traction bracket are fixedly connected to the front and rear sides of the annular chain for pulling the upper and lower feeding trays to move in opposite directions or in the opposite direction. A guide bracket is fixedly installed at the middle of the mobile machine platform and has a guide elongated hole in the guide bracket for adjusting the height of the lower feeding tray during its displacement to avoid obstruction to the upper feeding tray. The sorting section consists of two sets, which are respectively set on the upper and lower feeding trays. Each set includes a barcode scanner and a locking device for the corresponding end of the aluminum ammonia heat pipe. The barcode scanner is used to identify the model QR code on the aluminum ammonia heat pipe, and the locking device includes two silicone clamps as a set. The two silicone clamps are used to clamp the aluminum ammonia heat pipe end in opposite directions or expand in the opposite direction to fix the end of the aluminum ammonia heat pipe, and adjust the aluminum ammonia heat pipe to be centered in the front-back direction when it is being picked up.

[0006] Preferably, the mobile platform includes a load-bearing plate, and the front and rear sides of the load-bearing plate are integrally connected with a first guide rail for movably supporting the upper material tray, and the middle section of the load-bearing plate is symmetrically provided with a second guide rail for movably supporting the lower material tray. The mobile platform also includes a load-bearing truss integrally welded to the left end of the first guide rail.

[0007] Preferably, the first guide rail is higher than the second guide rail.

[0008] Preferably, two drive sprockets with meshing connected ring chains are rotatably mounted on the load-bearing plate, and the ring chains reciprocate 1 / 2 turn through the two drive sprockets.

[0009] Preferably, an n-shaped lifting slider is slidably mounted on the second guide rail and fixedly connected to the lower material tray.

[0010] Preferably, the guide hole consists of a first transverse cut, an oblique cut, and a second transverse cut.

[0011] Preferably, the sorting part includes a movable slider that slides horizontally in a left-right direction, and a Y-shaped telescopic rack that slides horizontally in a front-back direction is movably mounted in the movable slider, and the locking device is located on the Y-shaped telescopic rack.

[0012] Preferably, the two silicone clamps are arranged symmetrically, one above the other.

[0013] Preferably, the free section of the silicone clamp that contacts the aluminum ammonia heat pipe has a semi-cylindrical structure.

[0014] Preferably, the outer wall surface of the free section of the silicone clamp is an arc surface corresponding to the end hole of the aluminum ammonia heat pipe, and a purlin is integrally connected at the center line of the arc surface; the inner wall surface of the silicone clamp is a plane corresponding to the end plate surface of the aluminum ammonia heat pipe.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This invention employs staggered first and second guide rails, and simultaneously drives the first and second traction supports via a single annular chain. In terms of structural linkage, a guide elongated hole composed of a first transverse cut, an oblique cut, and a second transverse cut cooperates with the crossbar on the n-shaped lifting slider, allowing the lower material tray to automatically adjust its height along the oblique cut during horizontal movement, thus achieving obstacle avoidance in the space below the upper material tray. This enables synchronous movement and interlocking avoidance between the upper and lower material trays, allowing one tray to pick up material while the other tray is unloading in parallel, eliminating waiting time between processes and significantly improving space utilization and work cycle time.

[0016] 2. This invention integrates a sorting unit containing a barcode scanner, a moving slider, and a locking device at the upper and lower feeding trays. Functionally, the barcode scanner reads the workpiece model, and the control system then drives the drive turntable and traction swing arm to precisely position the moving slider above the workpiece. The locking device is then fed to the end of the workpiece via a drive gear and a Y-shaped telescopic rack. By integrating automatic identification and active sorting / alignment functions onto the moving tray, precise positioning and clamping of the workpiece can be completed during transport waiting intervals, ensuring that each aluminum ammonia heat pipe is centered and in a consistent posture before entering the next gripping process.

[0017] 3. This invention enables the locking device to employ two silicone clamping components driven by a worm gear and an eccentric traction yoke. Its structural characteristics give the device two working modes: the two silicone clamping components can move towards each other to clamp the outer wall of the heat pipe; or move in opposite directions, using their arc surfaces and purlins to expand and fix the heat pipe port hole from the inside out. The dual selectable clamping method can adapt to the gripping of solid outer walls and can also extend into and support hollow ports, effectively avoiding damage to the appearance of the pipe fittings, and can stably hold open thin-walled parts with easily changeable structures, thereby expanding the device's compatibility with aluminum-ammonia heat pipes of different specifications and with different process requirements.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-11 A partitioned multi-station loading and unloading platform includes a movable platform 1, an upper loading tray 2 and a lower loading tray 3 for carrying aluminum-ammonia heat pipes, and also includes a feeding section 4 and a sorting section 5. (See reference...) Figure 11The aluminum-ammonia heat pipe is an I-beam structure with interconnected through holes at both ends. Multiple circumferentially spaced slits are provided around the through holes to facilitate later sealing and plugging. It should be noted that robotic arms are installed on both sides of the mobile machine 1 to handle and move the aluminum-ammonia heat pipes to be processed. As this is existing technology, it will not be described in detail. The aluminum-ammonia heat pipe is coated with a QR code containing its specifications, model and other information.

[0022] In some implementations, refer to Figure 2 The mobile platform 1 includes a load-bearing plate 11. The load-bearing plate 11 is integrally connected to the front and rear sides with a first guide rail 12 for movable support of the upper feeding tray 2. The load-bearing plate 11 is symmetrically provided with a second guide rail 13 for movable support of the lower feeding tray 3 in the middle section. The first guide rail 12 is higher than the second guide rail 13. The width of the upper feeding tray 2 is greater than the width of the lower feeding tray 3 to avoid them from interfering with each other.

[0023] The mobile platform 1 also includes a load-bearing truss 14 integrally welded to the left end of the first guide rail 12, for mounting a barcode scanner 51 at a high position to facilitate the identification of the QR code on the aluminum ammonia heat pipe from top to bottom.

[0024] In some implementations, refer to Figures 1-4 Both the upper feeding tray 2 and the lower feeding tray 3 are provided with slots for placing aluminum ammonia heat pipes.

[0025] In some implementations, refer to Figure 2 The feeding unit 4 is set on the mobile platform 1 and includes two drive sprockets 41 rotatably mounted on the front side of the load plate 11. At least one of them is a drive sprocket. The hub of the drive sprocket is connected to the output shaft of the servo motor reducer through a shrink sleeve. The servo motor is preferably equipped with an absolute encoder to achieve precise angle control of the reciprocating rotation of the ring chain 42 by 1 / 2 turn.

[0026] A ring chain 42 located at the front of the moving platform 1 is connected between two drive sprockets 41. The ring chain 42 reciprocates 1 / 2 turn via the two drive sprockets 41. When the drive sprocket rotates 180° clockwise, the upper section of the ring chain 42 moves to the right and the lower section moves to the left, thereby driving the first traction bracket 43 and the second traction bracket 44 to move in opposite directions. The two ends of the ring chain 42 pass around the two drive sprockets 41 and are fixed to the corresponding sides of the first traction bracket 43 or the second traction bracket 44, forming a closed-loop force transmission path. When the servo motor drives the drive sprocket to rotate 180° clockwise, the upper section of the ring chain 42 moves to the right and the lower section moves to the left at the same speed, driving the first traction bracket 43 to move to the right and the second traction bracket 44 to move to the left; reversing 180° achieves reverse reset, thereby completing the interlocking displacement of the upper feeding tray 2 and the lower feeding tray 3 in opposite directions.

[0027] Reference Figure 1 The annular chain 42 has a first traction bracket 43 and a second traction bracket 44 fixedly connected to its front and rear sides, respectively, for pulling the upper feeding plate 2 and the lower feeding plate 3 to move in opposite directions. An n-shaped lifting slider 45 is longitudinally slidably mounted on the second guide rail 13 and fixedly connected to the lower feeding plate 3. The n-shaped lifting slider 45 has a linear bearing embedded inside, forming a rolling friction pair with the optical axis of the second guide rail 13 to reduce lifting resistance. The ends of the crossbar 48 are bolted to the side walls of the n-shaped lifting slider 45. Its outer diameter and the groove width of the guide hole 47 are H7 / g6 clearance fit, and it is coated with molybdenum disulfide grease to ensure smooth movement.

[0028] Reference Figure 4 A guide bracket 46 is fixedly installed at the middle position of the mobile machine platform 1. The guide bracket 46 consists of two upright plates symmetrically arranged on both sides of the middle section of the mobile machine platform 1. Each upright plate has a guide hole 47 with the same outline to ensure that the crossbar 48 is subjected to balanced force at both ends and to prevent the n-type lifting slider 45 from being jammed due to uneven load.

[0029] Reference Figure 5 The guide bracket 46 has a guide elongated hole 47 for adjusting the height of the movable traction lower feeding plate 3 during displacement to avoid obstruction to the upper feeding plate 2. The n-type lifting slider 45 is fixedly installed with a movable through guide elongated hole 47, and the n-type lifting slider 45 is fixedly installed with a crossbar 48 that is movable through guide elongated hole 47.

[0030] Reference Figure 4 and Figure 5 The guide hole 47 is composed of a first transverse cut 471, an oblique cut 472 and a second transverse cut 473.

[0031] When the second traction bracket 44 pushes the n-shaped lifting slider 45 to the left and enters the area of ​​the first transverse cut 471, the lower material tray 3 maintains a high position and moves horizontally. When the crossbar 48 enters the inclined cut 472 section, the inclination angle (the angle between the inclined cut 472 and the horizontal direction) is designed to be 15° to 25°, so that the crossbar 48 slides smoothly down the groove wall, driving the lower material tray 3 to descend. The descent stroke is determined by the vertical projection length of the inclined cut 472. Subsequently, when entering the second transverse cut 473 section, the lower material tray 3 has already moved horizontally to the left end working position at a safe height below the plane below the upper material tray 2, avoiding interference with the upper material tray 2 throughout the process.

[0032] Further explanation: The angle of the oblique cut 472 of the guide hole 47 can be designed based on the ratio of the obstacle avoidance height of the lower material tray 3 to the horizontal displacement stroke. In a preferred embodiment, the angle is set to 20° to maximize the coupling efficiency of the horizontal displacement and vertical descent while ensuring smooth descent. Wear-resistant copper sleeves can be fitted at both ends of the crossbar 48 to further reduce the sliding friction coefficient with the groove wall of the guide hole 47. Regarding the control method of 1 / 2 revolution reciprocating rotation, in addition to the absolute encoder, the servo motor can also be equipped with a proximity switch or photoelectric sensor at the shaft end of the drive sprocket as the origin reset signal. After each cycle, a zero-return calibration is performed to eliminate accumulated errors and ensure that the positioning accuracy of the first traction bracket 43 and the second traction bracket 44 is within ±0.2mm during long-term operation.

[0033] In some embodiments, there are two sets of sorting units 5, which are respectively set on the upper feeding tray 2 and the lower feeding tray 3. Each set includes a barcode scanner 51 movably mounted on the load-bearing truss 14. A drive turntable 52 is rotatably mounted at the lower end of both the upper feeding tray 2 and the lower feeding tray 3. The drive turntable 52 is directly connected to the rotor of a stepper motor fixed to the bottom surface of the upper feeding tray 2 or the lower feeding tray 3 via a rotating shaft. The step angle of the stepper motor is 1.8°, and it achieves high-resolution angular displacement in conjunction with a 16 microstepping driver.

[0034] Reference Figure 8 and Figure 9 The upper and lower feeding trays 2 and 3 are equipped with traction swing rods 53, which are movably pulled by the drive turntable 52 to perform oscillating motion. Moving sliders 54, which are movably pulled by the traction swing rods 53 to perform linear reciprocating motion in a left-right direction, are movably mounted on the upper and lower feeding trays 2 and 3. A pin hole is formed off-center on the surface of the drive turntable 52, and one end of the traction swing rod 53 is hinged to this pin hole via a spherical bearing. When the drive turntable 52 rotates, its eccentric pin hole drives the traction swing rod 53 to reciprocate around its fixed pin at the other end, with an oscillation angle range of ±30°. This angular displacement is converted into the left-right linear reciprocating motion of the moving slider 54 through a linkage mechanism. Similarly, the free end of the traction lever 53 has a slot, and the movable slider 54 is integrally connected with a traction bolt that is movably fitted into the slot. By controlling the rotation angle of the drive turntable 52, the movable slider 54 can be precisely stopped at multiple preset positions or at consecutive positions in the horizontal direction (within a certain stroke range) to meet the positioning requirements of slots with different spacing.

[0035] Reference Figure 9A drive gear 55 is rotatably mounted on the movable slider 54, and a Y-shaped telescopic rack 56, meshing with the drive gear 55, is slidably mounted in the movable slider 54. The drive gear 55 is a spur gear with a module of 0.8, and its shaft end is driven by a micro servo motor. A planetary reducer can be added between the motor and the drive gear 55 to increase the torque. One side of the Y-shaped telescopic rack 56 is machined with straight teeth of the same module as the drive gear 55, forming a gear and rack transmission pair. A locking device 57 corresponding to the end of the aluminum-ammonia heat pipe is provided on the Y-shaped telescopic rack 56. A guide groove is opened at the Y-shaped fork end of the Y-shaped telescopic rack 56, which cooperates with the linear guide rail on the movable slider 54 to ensure the straightness of the telescopic movement. The servo motor adopts a position control mode, and the extension length of the Y-shaped telescopic rack 56 is precisely controlled by setting the number of pulses, thereby delivering the locking device 57 to the predetermined clamping position at the end of the aluminum-ammonia heat pipe.

[0036] The drive turntable 52 and the traction rocker arm 53 constitute an evolution of a crank-rocker mechanism, where the drive turntable 52 is the crank, the traction rocker arm 53 is the rocker arm, and the moving slider 54 is equivalent to a connecting rod end effector. By pre-setting different rotation angle-displacement mapping tables for the drive turntable 52, the positions of the placement slots in different rows and columns on the material tray can be programmed and addressed, so that the moving slider 54 can be precisely stopped at the x-axis coordinate corresponding to any placement slot.

[0037] Furthermore: The barcode scanner 51 is used to identify the model QR code on the aluminum ammonia heat pipe. It should be noted that the mobile machine 1 is equipped with a central controller that connects the barcode scanner 51 and the sorting unit 5. The controller makes corresponding adjustments based on the information obtained by scanning the barcode with the barcode scanner 51.

[0038] Reference Figure 10 The locking device 57 includes a worm gear 571 rotatably mounted in a Y-shaped telescopic rack 56, the worm of which is driven by a precision miniature DC geared motor. Two driven worm gears 572 are rotatably mounted on the Y-shaped telescopic rack 56 and mesh with the worm gear 571. Silicone clamping members 573 are slidably mounted on the Y-shaped telescopic rack 56, which are moved in opposite directions by the driven worm gears 572. When the driven worm gears 572 rotate, the traction yoke 574 slides along the driven elongated hole 575, driving the two silicone clamping members 573 to move towards each other to clamp the outer wall of the heat pipe, or to open in the opposite direction to support the inner wall of the heat pipe.

[0039] To further explain, the precision micro DC geared motor can achieve seamless switching of clamping modes by switching between forward and reverse directions. The self-locking characteristic of the worm gear 571 ensures that the clamping force is maintained even when the power is off, preventing the workpiece from falling off.

[0040] The worm of the worm gear 571 adopts a double lead design. By adjusting the relative position of the worm along the axis, the meshing backlash of the worm gear pair can be eliminated, thereby improving the positional repeatability accuracy of the silicone clamping part 573 in both clamping and expansion modes.

[0041] Reference Figure 10 On the working surface of the silicone clamp 573 in contact with the alumina heat pipe, a corrugated or granular micro-anti-slip texture can be added to increase the static friction coefficient and ensure that the alumina heat pipe does not slip relative to each other during high-speed cleaning and moving. The eccentric traction yoke 574 of the driven worm gear 572 and the driven elongated hole 575 constitute a cylindrical cam driven mechanism. The rotation of the driven worm gear 572 from 0° to 180° corresponds to the stroke of the silicone clamp 573 from fully open to fully closed. The two have an approximately linear relationship, which facilitates the precise adjustment of clamping force or expansion amount by controlling the motor rotation angle.

[0042] An eccentrically positioned traction yoke 574 is integrally connected to the driven worm gear 572, and a driven elongated hole 575 for the movable traction yoke 574 is provided in the silicone clamping member 573.

[0043] Two silicone clamps 573 form a group. The two silicone clamps 573 are used to clamp or expand in opposite directions to fix and pick up the end of the aluminum ammonia heat pipe. After the front locking device 57 of the Y-shaped telescopic rack 56 contacts the end of the aluminum ammonia heat pipe, the torque closed-loop control can be realized by monitoring the current or torque feedback of the micro servo motor. When the current sudden change exceeds the preset threshold, it is determined that the locking device 57 has reached the predetermined clamping depth, and the servo motor stops feeding to prevent excessive pushing and damage to the aluminum ammonia heat pipe. In the picking state, the aluminum ammonia heat pipe is adjusted to be placed in the center along the front and back direction.

[0044] To verify the impact of the interlocking avoidance and centering functions of the double-layer tray on production efficiency and positioning accuracy, a test platform was constructed using the publicly disclosed independent double-layer tray structure as a comparative example for comparative experiments. The experimental conditions were as follows: the aluminum-ammonia heat pipes were 8mm in diameter and 200mm in length, with 20 pipes loaded on a single tray, and the test cycle was 100 times.

[0045] Comparative experimental data table:

[0046] This invention utilizes a single ring chain 42 to synchronously drive the upper feeding tray 2 and the lower feeding tray 3, and achieves active obstacle avoidance of the lower feeding tray 3 through the oblique cut 472 of the guide elongated hole 47, eliminating waiting time and increasing cycle time by more than 45%. In terms of positioning accuracy, the independent double-layer material tray lacks a sorting part 5, resulting in a large positional dispersion of the aluminum ammonia heat pipe after the material tray moves. During the conveying waiting interval, the present invention uses a barcode scanner 51 to feed back position information to the addressing mechanism composed of the drive turntable 52 and the traction swing rod 53, and then the locking device 57 completes secondary centering and clamping, controlling the positional deviation within 0.5mm, which greatly reduces the failure rate of subsequent robotic arm grasping. In terms of switching, this invention uses a worm gear 571 to drive the silicone clamping component 573 to move in opposite directions. Only the direction of the motor needs to be controlled to switch between the inner support and outer clamping modes. No hardware needs to be replaced, which has extremely strong compatibility and verifies the high flexibility advantage of the dual clamping mode in actual production.

[0047] Two silicone clamping parts 573 are symmetrically arranged vertically to facilitate symmetrical operation for clamping or expanding fixation.

[0048] In some embodiments, to achieve targeted fixation of the aluminum ammonia heat pipe, the outer wall surface of the free section of the silicone clamp 573 is an arc surface corresponding to the end hole of the aluminum ammonia heat pipe, and a purlin is integrally connected at the center line of the arc surface. The radius matches the inner diameter of the flange of the end hole of the aluminum ammonia heat pipe. When the expansion fixation mode is executed, the purlin is embedded behind the flange of the hole to form an axial mechanical limit, preventing the heat pipe from coming out axially during the arrangement process.

[0049] Furthermore, the inner wall surface of the silicone clamp 573 is a plane corresponding to the end plate surface of the aluminum ammonia heat pipe, providing a larger surface contact area to disperse the clamping force and avoid plastic deformation of the outer wall of the heat pipe.

[0050] It should be noted that the specific model and specifications of the barcode scanner 51 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0051] The functional principle of this invention can be explained through the following operational methods: When the upper feeding tray 2 is at the left end of the moving machine 1, the external robotic arm is used to place the aluminum ammonia heat pipe of the model to be processed on the upper feeding tray 2. The barcode scanner 51 scans and identifies the aluminum ammonia heat pipe located on the upper feeding tray 2, controls the drive turntable 52 to rotate, causes the traction swing arm 53 to swing, and then drives the moving slider 54 to move to the position of the corresponding aluminum ammonia heat pipe. The drive gear 55 is rotated, causing the Y-shaped telescopic rack 56 to move horizontally until the locking device 57 corresponds to the end of the aluminum ammonia heat pipe. The worm gear 571 is then rotated, causing the two driven worm gears 572 to rotate. The driven worm gears 572 drive the two silicone clamping parts 573 to move towards each other through the driven elongated hole 575 and the traction yoke 574, so as to clamp and fix the outer wall of the aluminum ammonia heat pipe. Alternatively, the two silicone clamping parts 573 can move in opposite directions to expand and fix the port of the aluminum ammonia heat pipe from the inside out.

[0052] Controlling one of the drive sprockets 41 to rotate, the two drive sprockets 41 drive the ring chain 42 to rotate 1 / 2 turn periodically. The first traction bracket 43 drives the upper feeding tray 2 to move horizontally to the right along the first guide rail 12 to the right end of the moving platform 1. At the same time, the second traction bracket 44 drives the n-shaped lifting slider 45 to move to the left on the second guide rail 13. During this process, the n-shaped lifting slider 45 drives the crossbar 48 to move synchronously to the left along the guide hole 47. Because of the oblique cut 472, the lower feeding tray 3 moves from the position below the upper feeding tray 2 to the left end of the moving platform 1.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
