Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and in particular to a heat exchanger assembly device. Background Technology

[0002] Plate heat exchangers are a type of high-efficiency heat exchanger composed of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the various plates, through which heat exchange occurs. During the assembly of plate heat exchangers, standardized procedures must be strictly followed. The heat exchanger plates must be stacked neatly and compacted to ensure that the gaskets are cured and do not shift. Most importantly, the order of installation of the heat exchanger plates requires observation of the markings on the heat exchanger plates, ensuring that they are rotated 180 degrees and stacked alternately.

[0003] During installation, the heat exchanger plates have the same shape, complex surface corrugations, and a large number of stacked plates. This can easily lead to visual fatigue and misremembering the plate order during manual assembly and stacking. In addition, to facilitate hoisting and keep the heat exchanger upright during installation, the heat exchanger plates need to be bent after the upper and lower guide rods are installed on the clamping plate. The efficiency of the heat exchanger plates is greatly reduced due to the obstruction of the upper and lower guide rods, and the bending of the heat exchanger plates can also easily cause metal fatigue of the plates, reducing their service life.

[0021] This invention provides a heat exchanger assembly device, the advantages of which are:

[0022] 1. By setting up other mechanisms such as the movable seat, positioning block and the upward folding edges on the left and right sides of the support plate, the fixed clamping plate can be accurately positioned horizontally. This makes it convenient to install heat exchange plates vertically on the surface of the fixed clamping plate when it is placed horizontally. The horizontal installation operation improves the stability of the heat exchange plates during installation and avoids bending of the heat exchange plates during the installation process.

[0023] 2. By switching the states of the two sets of suction cups, the two sets of perforated suction cups can cross-stack the heat exchange plates on the left and right sides of the tray. As the tray storing the heat exchange plates is raised step by step, the telescopic mechanism B linked with it retracts step by step, causing the fixed clamping plate to move down step by step. This ensures that the fixed clamping plate and the heat exchange plates on the left and right sides always maintain the height distance, which can maintain the stability of the heat exchange plate movement and combination. After placing two sets of heat exchange plates of the same number but different orientations on the top of the tray, they can be stably stacked and combined, which can avoid the error of the traditional manual plate loading and installation sequence.

[0024] 3. By controlling the operation of the telescopic mechanism A through the industrial control host system program, it can control the telescopic part of the telescopic mechanism A to extend outward and drive the undulating frame to move downward. When the undulating frame moves downward, the gripper rod flips inward and retracts. The bent part at the top end of the gripper rod clamps and fixes the top of the movable clamping plate, which prevents the heat exchange plate and the movable clamping plate from shifting when the clamping bolts are installed after the heat exchanger is erected. At the same time, it facilitates the bonding and curing of the gaskets inside the heat exchange plate.

[0025] 4. By controlling the telescopic mechanism D on both sides in conjunction with the telescopic mechanism B and other mechanisms through the industrial control host system, the left and right sides can be driven to lift the support plates in a step-by-step manner according to the heat exchange plates. This ensures that the heat exchange plates and the fixing clamping plate on both sides are always at a specific height. While the support plates are lifting in a step-by-step manner, the fixing clamping plate can be lowered synchronously. This ensures that the relative height between the heat exchanger plates to be installed and the heat exchanger plates already installed by the multi-hole suction cups on both sides remains constant. This eliminates the vertical stroke change time required when transferring heat exchanger plates by the suction cup structure, thereby improving the efficiency of heat exchanger plate installation.

[0026] 5. The operator controls the telescopic mechanism A to retract via the industrial control host, releasing the vertical restriction of the positioning block on the fixed clamping plate. Simultaneously, during the continuous retraction of the telescopic mechanism A, the positioning rod B extends outward inside the discharge pipe, and the end of the positioning rod B pushes the fixed clamping plate, causing the assembled heat exchanger to fall off the pallet. This facilitates the assembly of the heat exchanger to fall off to the discharge and collection mechanism for lifting or to the chain conveyor belt for outward transport, with the support column on the outside of the movable clamping plate added.

[0042] The details of the present invention can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of the present invention described herein are for illustrative purposes only and should not be construed as limiting the invention in any way. Under the teachings of this invention, those skilled in the art can conceive of any possible modifications based on the invention, and these should all be considered to fall within the scope of the invention.

[0043] Unless otherwise defined, the directions such as up, down, left, and right mentioned herein refer to the directions shown in this invention. Figure 1 The directions such as up, down, left, and right are used as a reference, and will be explained here together.

[0044] Please see Figure 1-9Embodiment 1 of the present invention: The present invention provides a heat exchanger assembly device, including a fixed clamping plate receiving mechanism, a heat exchanger plate stacking mechanism, a movable clamping plate installation mechanism, and a discharge and storage mechanism. The fixed clamping plate receiving mechanism includes a support plate 1, with bolt mounting grooves 101 on both the left and right sides of the support plate 1, a limit hole 102 through the support plate 1, a positioning rod A103 fixedly connected to the bottom surface of the support plate 1, a discharge pipe 104 vertically arranged inside the support plate 1, and a telescopic mechanism A105 fixedly connected to the bottom of the support plate 1, allowing the bottom of the support plate 1 to rotate. Two sets of transmission gears 106 are connected. The front end of the support plate 1 is provided with a foot groove 107. After the fixed clamping plate is placed on the top of the support plate 1, the telescopic mechanism A105 is controlled by the system to extend outward so that it drives the undulating frame 3 to move downward. During the downward movement of the toothed plates B304 at both ends of the undulating frame 3, the transmission gears 106 meshing with them drive the toothed plates A202 on the front and rear sides and the positioning block 201 to move upward. The positioning block 201 and the upward folding edges on the left and right sides of the support plate 1 can accurately position the fixed clamping plate.

[0045] The heat exchanger plate stacking mechanism includes two sets of plate frames 7. A telescopic mechanism D701 is installed inside the plate frames 7. Four sets of ball-head columns 702 are fixedly connected to the top of the plate frames 7. The outer diameter of the ball-head columns 702 corresponds to the inner diameter of the through holes in the heat exchanger plates. The through holes in the heat exchanger plates are clearance-fitted with the ball-head columns 702. A support plate 703 is fixedly connected to the top of the telescopic part of the telescopic mechanism D701. Four through holes are vertically penetrating the interior of the support plate 703. The support plate 703 is slidably connected to the ball-head columns 702. The telescopic mechanisms D701 on both sides are controlled by the industrial control host 11 system to operate in coordination with other mechanisms, allowing them to drive the support plates 703 on both sides to rise in a step-by-step manner according to the heat exchanger plates. This ensures that the uppermost heat exchanger plate on both sides of the support plates 703 is always kept in place. Holding at a specific height, the telescopic end of the telescopic mechanism B401 is synchronously retracted under the control of the industrial control host 11. This allows the fixed clamping plate to descend synchronously while the support plate 703 is raised in steps, ensuring that the relative height of the multi-hole suction cups 507 on both sides remains constant between the heat exchanger plates to be installed and the already installed heat exchanger plates. This eliminates the need for vertical stroke conversion time during heat exchanger plate transfer using the suction cup structure, improving the efficiency of heat exchanger plate installation. Furthermore, dividing the heat exchanger plates into two groups of the same number and rotating one group of plates 180 degrees to fit onto the ball head column 702 allows for high-precision definition of the horizontal angle and orientation of the plates, avoiding errors in the installation direction of a large number of plates and facilitating the precise installation of the next step.

[0046] The movable clamping plate mounting mechanism includes an outer bracket B8, which is located behind the outer bracket A5. A telescopic mechanism E801 is fixedly connected to the top of the outer bracket B8, and a guide rail B802 is also fixedly connected to the top of the outer bracket B8. A guide rail C803 is longitudinally slidably connected to the inner side of the guide rail B802. The telescopic part of the telescopic mechanism E801 is fixedly connected to the side of the guide rail C803. A power slide B804 is provided inside the guide rail C803. The gear at the motor of the power slide B804 meshes with the rack inside the guide rail C803 for transmission. A telescopic mechanism F8041 is installed inside the power slide B804. A flange sleeve 805 is fixedly connected to the bottom end of the telescopic part of the telescopic mechanism F8041. A telescopic clamping mechanism is installed inside the flange sleeve 805. In other embodiments, the telescopic clamping mechanism inside the flange sleeve 805 can be replaced by a three-jaw chuck structure or a shutter mechanism to limit the movement of the connecting flange. A limit switch is provided at the clamping end of the telescopic clamping mechanism. The conveyor belt 9, via stepping operation, transports the movable clamping plate to below the guide rail C803. After being detected and identified by the quality inspection camera 13, the image data is used to control the telescopic mechanism E801 and the servo motor inside the power slide B804 to move the flange sleeve 805 to directly above the movable clamping plate at the top edge of the conveyor belt 9. Through linkage with the telescopic mechanism F8041, the flange sleeve 805 is moved downwards and then fitted onto the outside of the connecting flange at the top of the movable clamping plate. By controlling the telescopic and lateral movement of the limiting mechanism 806, the limiting block is moved to below the connecting flange to form a limit. When the flange sleeve 805 moves upwards, it can lift the movable clamping plate. Through the cooperation of various mechanisms above the outer support B8, the movable clamping plate in the conveying process can be moved above the fixed clamping plate of the stacked heat exchange plates, so that the movable clamping plate can be installed and positioned.

[0047] A conveyor belt 9 is installed on the left side below the outer support B8. The surface of the conveyor belt 9 is equipped with dividing strips. The conveyor belt 9 is driven by a three-phase asynchronous motor. The spacing is limited by the dividing strips. After the movable clamping plate is conveyed through the conveyor belt 9, it is convenient to install the movable clamping plate in the next step.

[0048] The discharge and storage mechanism includes a fixed frame 10, which is located on the front side of the rack and pinion transmission guide rail frame A4. A buffer frame 1001 is connected to the top of the fixed frame 10 via a spring damper. A roller is rotatably connected to the inner side of the buffer frame 1001. Elastic movable sleeves 1002 are slidably connected to the left and right sides of the buffer frame 1001. A ball spring rod 1003 is provided inside the movable end of the elastic movable sleeve 1002, and a ball is rotatably connected to the end of the ball spring rod 1003. The fixed end of the sheath 1002 is fixedly connected to the fixed frame 10. The gears of the three-phase asynchronous motor inside the rack and pinion drive guide rail frame B402 engage with the top rack of the rack and pinion drive guide rail frame A4, causing the rack and pinion drive guide rail frame B402 to slide forward from the top to the front end of the rack and pinion drive guide rail frame A4. Then, the telescopic mechanism C403 is operated by system control, causing its telescopic part to extend outwards and causing the support plate 1 to flip upwards, thus vertically positioning the heat exchanger. Workers can then adjust the fixed clamping plate and the movable clamping plate. The clamping bolts are inserted and installed on the plate. The reserved bolt installation slot 101 facilitates the installation of nuts. After the clamping bolts tighten the clamping plate, the operator controls the telescopic mechanism A105 to retract via the industrial control host 11. This causes the undulating frame 3 to shorten the distance between itself and the support plate 1. The gripper rod 301 expands outward to stop clamping the movable clamping plate. During the further retraction of the telescopic mechanism A105, the movable seat 2 moves in the opposite direction to the undulating frame 3. The positioning block 201 retracts into the limiting hole 102, releasing the positioning block 201 from the fixed position. The clamping plate is vertically limited, and during the continuous retraction of the telescopic mechanism A105, the positioning rod B303 extends outward inside the unloading tube 104. The end of the positioning rod B303 can push the clamping plate, which can cause the assembled heat exchanger to fall off the support plate 1. After the assembled heat exchanger falls into the buffer frame 1001 for buffering, it slides forward to the end. After the front end of the heat exchanger contacts the ball spring rod 1003, the spring rod elastically retracts for buffering, which can buffer and support the bottom and sides of the heat exchanger.

[0049] Ultrasonic atomizers 12 are installed on both sides of the outer bracket A5, with two sets of ultrasonic atomizers 12. Each ultrasonic atomizer 12 is externally connected to a liquid delivery system that is connected to the circuitry of the industrial control host 11. A quality inspection camera 13 is installed on the outside of the guide rail B802. The heat exchanger assembly also includes an industrial control system, which includes an industrial control host 11. The industrial control host 11 is located on the right side below the outer bracket B8, and a power distribution cabinet is installed below it. The industrial control host 11 controls the rack and pinion system. The control modules of the three-phase asynchronous motor, telescopic mechanism B401, electric three-way valve 5062, drive mechanism 501, power slide A601, telescopic mechanism D701, ultrasonic atomizer 12, and quality inspection camera 13 of the transmission guide rail frame A4 and rack and gear transmission guide rail frame B402 are connected. The conveying system is controlled by the industrial control host 11 to step-by-step operate, which can spray liquid droplets on the surface of the heat exchange plates on the left and right side trays 703 to avoid dust covering and affecting the porous suction cup 507 to pick up the heat exchange plates.

[0050] The movable seat 2 is located below the pallet 1. A positioning block 201 is fixedly connected to the top of the movable seat 2. The positioning block 201 slides vertically inside the limiting hole 102. A toothed plate A202 is fixedly connected to the side of the movable seat 2. The toothed plate A202 meshes with the transmission gear 106. An undulating frame 3 is provided below the pallet 1. The top of the undulating frame 3 is fixedly connected to the telescopic part of the telescopic mechanism A105. A gripper rod 301 is rotatably connected to the outside of the undulating frame 3. A hinged sleeve 302 is slidably connected to the outside of the gripper rod 301. The hinged sleeve 302 is rotatably connected to the outside of the pallet 1. A positioning rod B303 is fixedly connected to the top of the undulating frame 3. The positioning rod B303 is located in the unloading tube 10. 4. The internal sliding mechanism 3 has a toothed plate B304 fixedly connected to the outside of the undulating frame 3. The toothed plate B304 meshes with the transmission gear 106. The telescopic mechanism A105 is controlled by the system program of the industrial control host 11. After the heat exchange plates are stacked and the movable clamping plate is installed, it can control the telescopic part of the telescopic mechanism A105 to extend outward and drive the undulating frame 3 to move downward. When the undulating frame 3 moves downward, the gripper rod 301 flips inward and retracts. The bent part at the top end of the gripper rod 301 clamps and fixes the top of the movable clamping plate, which facilitates the bonding and curing of the gaskets in the plates and prevents the heat exchange plates and the movable clamping plate from falling off when the heat exchanger is installed vertically with clamping bolts.

[0051] A rack and pinion drive guide rail frame A4 is rotatably connected to the bottom of the pallet 1. A telescopic mechanism B401 is provided at the bottom of the rack and pinion drive guide rail frame A4. A rack and pinion drive guide rail frame B402 is slidably connected to the inner side of the rack and pinion drive guide rail frame A402. A telescopic mechanism C403 is rotatably connected to the inner side of the rack and pinion drive guide rail frame B402. The end of the telescopic part of the telescopic mechanism C403 is rotatably connected to the bottom of the pallet 1. The three-phase asynchronous motor inside the rack and pinion drive guide rail frame A4 is controlled by the industrial control host 11 to drive the rack and pinion drive guide rail frame A4 to move horizontally in the front and back directions through the gear and rack. This allows for the fixed-distance transfer of the heat exchanger it carries.

[0052] The outer bracket A5 is located outside the rack and pinion transmission guide rail bracket A4. A drive mechanism 501 is fixedly installed on the bottom inner side of the outer bracket A5. A gear shaft 502 is rotatably connected inside the drive mechanism 501. Two sets of gears are coaxially mounted on the left and right sides of the gear shaft 502. Gear-bearing cranks 503 are rotatably connected to the left and right sides of the outer bracket A5. The gears on the side of the gear-bearing cranks 503 mesh with the gears on the side of the gear shaft 502. A telescopic rod A504 is rotatably connected to the top of the connecting rod portion of the gear-bearing cranks 503.

The telescopic rod B5051 slides vertically inside the vertical pipe 602. A multi-hole suction cup 507 is fixedly connected to the bottom of the telescopic rod B5051. The bottom of the multi-hole suction cup 507 is interference-fitted. The structure includes a textured rubber pad 5071, a perforated suction cup 507 connected to a three-way pipe 5061, a telescopic mechanism B401, an electric three-way valve 5062, a drive mechanism 501, a power slide A601 circuit, and a telescopic mechanism D701 connected to an industrial control host 11. The telescopic mechanism B401, drive mechanism 501, power slide A601, and telescopic mechanism D701 are mainly driven by a reducer and a three-phase asynchronous motor. The industrial control host 11 system controls the linkage of these mechanisms. When it controls the stepping operation of the drive mechanism 501, it can cause the slide rail 5042 at the top of the telescopic rod A504 to intermittently rise and fall through the meshing transmission between the gear shaft 502 and the geared crank 503, allowing it to reciprocate horizontally with the power slide A604. 1. Synchronous coordination: The two sets of perforated suction cups 507 at the bottom of the sliding sleeve 505 rise and fall synchronously. In coordination with the stepping upward-moving support plates 703 on both sides, when the left suction cup moves downward to pick up the heat exchange plates on the left support plate 703, the electric three-way valve 5062 controls the right-side pipeline to gradually close, causing the suction cup on the right side above the clamping plate to stop picking up heat exchange plates, thus stacking them on top of the clamping plate. Through the coordination of the electric three-way valve 5062 and the drive mechanism 501, one set of suction cups can be kept in a picking state at all times during the movement of the two sets of suction cups, and the states of the two sets of suction cups can be switched. This allows the two sets of perforated suction cups 507 to cross-stack the heat exchange plates on the left and right support plates 703. Simultaneously, the support plate 703 storing the heat exchange plates is stepped up.The linked telescopic mechanism B401 retracts in a step-by-step manner, causing the fixed clamping plate to move downwards in a step-by-step manner. This ensures that the fixed clamping plate and the heat exchange fins on both sides maintain a consistent height distance, thus maintaining the stability of the heat exchange fin movement assembly. After placing two sets of heat exchange fins of the same number but different orientations on top of the support plate 703, they can be stably stacked and assembled, avoiding the errors in the traditional manual fin installation sequence.

[0053] Example 2: Figure 10 As shown, guide rod mounting slots 108 are provided at both the front and rear ends of the pallet 1. After the heat exchange plates and movable clamping plates are installed, and the pallet 1 and the heat exchanger are positioned vertically, the operator can then insert the guide rods from the upper and lower parts for installation.

[0054] Example 3: An automatic hoisting system is installed at both ends of the rack and pinion drive guide rail frame A4 and on the left side of the conveyor belt 9. Horizontal stepping chain conveyor belts are respectively installed at both ends of the rack and pinion drive guide rail frame A4. The stepping conveyor belts cooperate with the automatic hoisting system to automatically transport the fixed clamping plate, the finished heat exchanger and the movable clamping plate, which can further save manpower.

[0055] The specific usage and function of this embodiment: When using this invention, the fixing clamping plate is first hoisted onto the top of the pallet 1 by an automatic hoisting system. The telescopic mechanism A105 is extended outward by the system control, causing the undulating frame 3 to move downward. During the downward movement of the toothed plates B304 at both ends of the undulating frame 3, the transmission gears 106 meshing with them drive the toothed plates A202 on the front and rear sides and the positioning blocks 201 to move upward. The positioning blocks 201 and the upward folding edges on the left and right sides of the pallet 1 accurately position the fixing clamping plate. The industrial control host 11 controls the three-phase asynchronous motor inside the rack and pinion transmission guide rail frame A4 to operate, causing the rack and pinion transmission guide rail frame A4 to move horizontally in the front and rear directions through the gear and rack engagement, thus fixing the clamping plate. The clamping plate is transferred at a fixed distance to the middle of the two sets of plate frames 7. After the two sets of heat exchange plates with the same number but different placement directions are placed on top of the support plate 703, the above mechanisms are linked by the industrial control host 11 system. When the control drive mechanism 501 steps, it drives the slide rail 5042 on the top of the telescopic rod A504 to rise and fall intermittently through the meshing transmission of the gear shaft 502 and the gear crank 503. This makes it work synchronously with the horizontally reciprocating power slide A601. The two sets of multi-hole suction cups 507 at the bottom of the sliding sleeve 505 rise and fall synchronously. Through cooperation with the stepping upward support plates 703 on both sides, when the left suction cup moves down to pick up the heat exchange plate on the left support plate 703, the electric three-way valve 5062 controls the right pipeline to gradually close, so that the right side is above the clamping plate. The suction cups stop sucking, allowing the heat exchange plates to stack on top of the clamping plate. Through the coordination of the electric three-way valve 5062 and the drive mechanism 501, one set of suction cups is kept in a sucking state during the movement of the two sets of suction cups, and the states of the two sets of suction cups are switched. This causes the two sets of perforated suction cups 507 to cross-stack the heat exchange plates on the left and right side support plates 703. As the support plate 703 storing the heat exchange plates is raised stepwise, the linked telescopic mechanism B401 retracts stepwise, causing the fixed clamping plate to move stepwise downwards. This ensures that the fixed clamping plate and the heat exchange plates on both sides maintain a consistent height distance. After the fixed clamping plate with the heat exchange plates installed is conveyed forward to below the outer support B8, the conveyor belt 9 steps forward, transferring the movable clamping plate to the guide rail C803. Below, after the quality inspection camera 13 measures and identifies the distance, its image data enables the industrial control host 11 system to control the telescopic mechanism E801 and the internal motor of the power slide B804 to operate servo. This causes the flange sleeve 805 to move to the top edge of the conveyor belt 9 directly above the movable clamping plate. Through linkage with the telescopic mechanism F8041, the flange sleeve 805 moves downward, fitting onto the outside of the connecting flange at the top of the movable clamping plate. By controlling the telescopic movement of the limiting mechanism 806, the limiting block moves to below the connecting flange to form a limit. When the flange sleeve 805 moves upward, it lifts the movable clamping plate. Through the cooperation of various mechanisms above the outer support B8, the movable clamping plate in the conveying process is moved above the fixed clamping plate of the stacked heat exchange plates.The system controls the telescopic mechanism A105 to install and position the movable clamping plate. After the heat exchange plates are stacked and the movable clamping plate is installed, the telescopic mechanism A105 is extended outward to move the undulating frame 3 downward. When the undulating frame 3 moves downward, the gripper rod 301 flips inward and retracts. The bent part at the top end of the gripper rod 301 clamps and fixes the top of the movable clamping plate, facilitating the bonding and curing of the gaskets inside the plates. The system controls the telescopic mechanism C403 to extend its telescopic part outward to flip the support plate 1 upward, thus vertically positioning the heat exchanger. The operator inserts and installs clamping bolts on the fixed clamping plate and the movable clamping plate, and installs nuts through the reserved bolt installation slots 101. After installation, the operator controls the support plate... As plate 1 moves backward, the operator controls the telescopic mechanism A105 to retract via the industrial control host 11. This causes the undulating frame 3 to shorten the distance between itself and the pallet 1. The gripper rod 301 expands outward, ending its clamping of the movable clamping plate. During the further retraction of the telescopic mechanism A105, the movable seat 2 moves in the opposite direction to the undulating frame 3. The positioning block 201 retracts into the limiting hole 102, releasing the vertical limitation of the positioning block 201 on the fixed clamping plate. Simultaneously, during the continuous retraction of the telescopic mechanism A105, the positioning rod B303 extends outward within the unloading pipe 104. The end of the positioning rod B303 pushes against the fixed clamping plate, causing the assembled heat exchanger to detach from the pallet 1. The assembled heat exchanger then falls to the discharge and collection mechanism for lifting or to the chain conveyor belt for outward transport to the support column with the movable clamping plate attached.
