Description

Technical Field

[0001] This invention relates to a coil used in heat exchange applications. More specifically, this invention relates to a device and method for mounting clips on the coil. Background Technology

Using the existing clamping process, the clamps need to be forcibly squeezed between the coil walls to create the required gap. This forced insertion is laborious, time-consuming, and can easily damage the coil itself. Summary of the Invention

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0021] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not list the presence or addition of one or more other elements or combinations thereof.

[0022] It should be noted that in the description of this invention, the orientations or positional relationships indicated by terms are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0024] Figure 1-4 An implementation of a device for mounting a clip on a coil according to the present invention is shown, comprising: a base 1; A rotating platform 2 is mounted on and rotatably connected to the base 1; Support platform 3 fixed on rotary table 2; Multiple positioning seats 4 are set on the support platform 3 to place the coil 8; A lifting mechanism 5 is installed on the rotary table 2 to lift and open the coil 8; A clamping assembly I6 is installed at the power output end of the lifting mechanism 5 to fix the upper end of the coil 8; A clamping assembly II 7 is installed on the support platform 3 to fix the lower end of the coil 8.

[0025] By setting up a support unit to fix the coil 8 and open the coil 8, sufficient gaps are made to allow for the installation of the clips 9, so that the clips 9 can be easily installed, reducing labor intensity and improving the installation efficiency of the clips 9. This avoids the risk of damaging the coil 8 body by forcibly installing the clips 9. At the same time, by setting up a rotating table 2, the coil 8 can be moved by rotating the rotating table 2, which makes it easier for the staff to evenly install the clips 9 on the side of the coil 8 from one side.

[0026] The base 1 and the rotating platform 2 are rotatably connected by a planar thrust bearing 11, which facilitates the normal and smooth rotation of the rotating platform 2 while bearing the pressure transmitted by the rotating platform 2.

[0027] The rotating platform 2 is provided with a protrusion that mates with the planar thrust bearing 11 by bolts; the planar thrust bearing 11 is inlaid in the base 1.

[0028] The clamping assembly I6 includes: a clamping cylinder I61 fixed to the power output end of the lifting mechanism 5; Multiple support angles I62 are installed at the power output end of the clamping cylinder I61 to clamp the upper side of the coil 8; The clamping assembly II7 includes: a clamping cylinder II71 fixed to the support platform 3; Multiple support angles II72 are installed at the power output end of the clamping cylinder II71 to clamp the lower side of the coil 8.

[0029] The support platform 3 is provided with multiple through holes for avoiding the clamping cylinder II 71, and a support column that can move up and down is inserted in the through holes; the upper end and lower end of the support column are respectively connected to the clamping cylinder I 61 and the power output end of the lifting mechanism 5, so as to drive the clamping cylinder I 61 to perform lifting and lowering movements when the clamping cylinder I 61 moves.

[0030] The positioning seat 4, support angle I 62 and support angle II 72 are all configured in fours, and their positions around the coil 8 are evenly arranged around the axis of placement; this ensures that the coil 8 is not easily tilted when it is clamped and fixed, which would affect the subsequent installation of the clip 9; the clamping cylinder I 61 and clamping cylinder II 71 are both configured as four-jaw finger clamping cylinders, and support angle I 62 and support angle II 72 are fixed on the fingers of the four-jaw finger clamping cylinder for movement.

[0031] The positioning seat 4 is provided with a boss 41 that cooperates with the inner side of the coil 8 to limit its movement; The positioning seat 4 is provided with a groove 42 for the support angle II 72 to move therein.

[0032] The protrusion 41 allows the coil 8 to be placed in the predetermined position more quickly and accurately, avoiding positional deviation, increasing adjustment steps, or causing deviations in the clamping positions of subsequent support angles II 72, which would affect work efficiency.

[0033] The heights of the positioning seat 4, support angle II 72 and support angle I 62 are adapted to the coil 8 so that the coil 8 is placed vertically on the mechanism.

[0034] In practical applications, the heights of each positioning seat 4, support angle II 72, and support angle I 62 are different. The heights need to be increased or decreased according to the spiral shape of the coil 8 so that the coil 8 is placed vertically on the positioning seat 4 and that support angle II 72 and support angle I 62 accurately clamp the vertically placed coil 8; so that the coil 8 can maintain a good tension state during subsequent stretching and clamp 9 installation.

[0035] The outer side of the support angle I62 is configured with a stop I621 whose upper extension length is less than the lower extension length; The outer side of the support angle Ⅱ72 is configured with a stop portion Ⅱ721 whose upper end protrusion length is greater than the lower end protrusion length.

[0036] The surfaces of the stop parts I 621 and II 721 that contact the coil 8 are both configured as arc shapes adapted to the coil 8. The shape of the stop parts I 621 and II 721 can maintain full contact with the coil 8 and avoid scratching the surface, while also preventing the upper and lower ends of the coil 8 from detaching from the stop parts I 621 and II 721 when the spiral coil 8 is opened, thus preventing the spiral coil 8 from failing to open.

[0037] The base 1 and the rotating platform 2 are equipped with corresponding scales to identify the predetermined rotation angle of the rotating platform 2. In the actual installation process, eight clips 9 need to be evenly installed on the surface of the coil 8. The rotating platform 2 is configured as a square, and scales are provided in the middle of each side and the middle of the front side of the base 1. When the rotating platform 2 is rotated to the point where the scales are aligned or the top corner of the rotating platform 2 is aligned with the scales of the base 1, it indicates that the rotation angle is 45 degrees. The clips 9 are then installed in the same position after rotation to ensure the uniformity of the clip installation.

[0038] The bottom of the rotary table 2 is equipped with an angle encoder. It can detect the rotation angle of the rotary table 2 each time, so that the rotation angle of the rotary table 2 can be precisely controlled, ensuring the accuracy of the installation of the clip 9.

[0039] This organization can also be used in conjunction with robotic arms and automated control systems to install clamp 9.

[0040] A method for installing spacer clips on a coil, comprising: Step 1: Place the coil 8 with the clip 9 to be installed vertically on the positioning seat 4; Step 2: The clamping cylinders I61 and II71 control the extension of the support angles I62 and II72, respectively clamping the upper and lower ends of the coil 8; Step 3: The lifting mechanism 5 drives the pressing cylinder I61 to rise, and through the support I62, it drives the coil 8 to move upward to open up the tightly wound spiral coil 8; Step 4: Rotate the rotating table 2 to drive the coil 8 to rotate, and during the rotation, evenly install the clips 9 into the gaps opened by the spiral coil 8; Step 5: The lifting mechanism 5 drives the clamping cylinder I 61 to descend to its original position; Step 6: The clamping cylinders I61 and II71 control the retraction of the support angles I62 and II72. After the support angles I62 and II72 separate from the coil 8, the coil 8 is removed.

[0041] By using this method to open up the coil 8 and install the clips 9, sufficient gaps can be left between the layers of the coil 8 so that the clips 9 can be easily installed, reducing labor intensity and improving the installation efficiency of the clips 9. This avoids the risk of damaging the coil 8 body by forcibly installing the clips 9. At the same time, the rotation of the rotating table 2 moves the coil 8, making it easier for workers to evenly install the clips 9 on the side of the coil 8 from one side, further improving work efficiency.

[0042] like Figure 5-8 As shown, in practical applications, it also includes: a card sorting unit 10 that neatly arranges and fixes the cards 9 and delivers them in sequence, and a card loading unit 110 that picks up the cards 9 delivered by the card sorting unit 10 and installs them into the coil 8. The clip 9 includes multiple comb teeth 91 that penetrate into the gaps between the coils 8 and a connecting handle 92 that connects each comb tooth 91 and is set close to the outside of the coils 8. The card sorting unit 10 includes: a conveyor belt I 101 for transporting the manufactured cards 9; Conveyor belt II 102 is installed above conveyor belt I 101 to ensure that the clip 9 is placed in a preset orientation on conveyor belt I 101 for transportation; A card storage component 103 is installed at the output end of conveyor belt I101 to store the card 9; It is positioned at the end of the card storage assembly 103 to move the card 9 sequentially to the delivery roller group 104 at its outlet.

[0043] The surface of the conveyor belt II 102 is uniformly provided with multiple sorting strips 1021 arranged perpendicular to the conveying direction of the conveyor belt I 101, and the running speed of the conveyor belt II 102 is greater than the transmission speed of the conveyor belt I 101. The spacing between the sorting strips 1021 is greater than the placement distance between two clips 9 on the conveyor belt; ensuring that the sorting strips 1021 can adjust and push each clip 9 individually. A pair of guide strips 105 arranged in a figure-eight shape are provided between conveyor belt I 101 and conveyor belt II 102, and the length of the sorting strip 1021 is not greater than the minimum distance between the two guide strips 105.

[0044] The card sorting unit 10 is provided with a card sorting bracket 106 for support and fixation below it.

[0045] The card storage assembly 103 includes: a card storage plate 1031 connected to the material output end of the conveyor belt I 101, and a limiting plate 1032 disposed at a predetermined distance above the card storage plate 1031 to limit the card 9 and prevent it from stacking in the vertical direction of the card storage plate 1031. The card storage plate 1031 is provided with a plurality of clearance slots 10311 along its extending direction for placing the card 9 comb teeth 91 therein; The card storage plate 1031 has a downward bending portion at its end. The bending portion has a large inclination angle, which facilitates the card mounting unit 110 to clamp the card 9. The width of the bending portion is less than the length of the card 9 and there is no limit plate 1032 extending above it, so as to avoid interference when the card mounting unit 110 clamps the card 9. The end of the bending portion has a stop comb 91 that directly drops the card 9 out of the card storage plate 1031. The flexible stop plate 10312 is set with an angle and height that are adapted to the card mounting unit 110. While stopping the card 9, it also buffers the card 9 on it and increases the friction between them, so as to prevent the card 9 from colliding with the flexible stop plate 10312 and falling directly from the opening above the avoidance groove 10311.

[0046] The delivery roller assembly 104 is fixed to the end of the limiting plate 1032, and it cooperates with the clamping unit 110 to complete the handover of the clamp 9. The delivery roller assembly 104 is configured as two delivery rollers, which are arranged side by side and both have an anti-slip skin layer on their surface. During operation, the delivery roller assembly 104 rotates. The delivery roller closer to the material receiving end rotates at a predetermined angle first, pushing one clamp 9 at the material receiving end under the other delivery roller and then stops rotating to prevent more clamps 9 from being moved. The other delivery roller continues to rotate, pushing the clamp 9 pushed by the previous delivery roller towards the bending part.

[0047] The mounting unit 110 includes: a mounting bracket 111; Fixed racks 112 and telescopic cylinders I 113 are respectively vertically installed on both sides of the mounting bracket 111; A telescopic rack 114 is installed at the power output end of telescopic cylinder I113; A rotating disk 115 is disposed between the telescopic rack 114 and the fixed rack 112, and is driven by the telescopic rack 114 to rotate and rise. Telescopic cylinder II 116 fixed to the tilting plate 115; A gripping mechanism 118 is fixed to the power output end of the telescopic cylinder II 116; The gripping mechanism 118 and the telescopic cylinder II 116 are connected and fixed by an elastic element 117; The gripping mechanism 118 includes: a gripping cylinder, a telescopic rod 1181 disposed at the power output end of the gripping cylinder, a pair of gripping arms 1182 that cooperate with both ends of the clamp 9 for gripping, a positioning push block 1183 disposed at the end of the telescopic rod 1181 and adapted to the surface of the connecting handle 92, and a limiting rod 1184 fixed to one end of the gripping cylinder to adapt to the height of the coil 8 when installing the clamp 9; the limiting rods 1184 are configured as a pair and are respectively located on both sides of one of the gripping arms 1182, and do not interfere with the position of the gripping arms 1182.

[0048] One end of the gripping arm 1182 is hinged to the telescopic rod 1181, and moves to clamp and release the clamp 9 as the telescopic rod 1181 moves. When the telescopic rod 1181 extends outward, the gripping arm 1182 releases the clamp 9, and the positioning push block 1183 at the top of the telescopic rod 1181 moves toward the clamp 9, pushing the clamp 9 to continue moving inward toward the coil, ensuring that the clamp 9 is installed in place. The telescopic rod 1181 extends and retracts, causing the gripping arm 1182 to clamp... The movable gripper cylinder is existing technology. The structure and movement of the gripper cylinder are similar to those of the pneumatic gripper in application number 201711443883.3, and will not be described in detail here. The surfaces of the positioning push block 1183, the gripper arm 1182 and the clamp 9 are all equipped with anti-slip layers. The surface of the positioning push block 1183 is provided with an arc-shaped groove that matches the surface of the clamp 9, so as to facilitate positioning and anti-slip when cooperating with the clamp 9.

[0049] When the gripping cylinder moves towards the coil, there is a deviation in the height position of the first coil of the coil 8 in various directions. Therefore, an elastic element 117 is set to connect and fix the gripping mechanism 118 and the telescopic cylinder II 116. A limiting rod 1184 is set to match the height of the coil 8. An inclined guide part 1185 is set on the lower surface of the limiting rod 1184 so that when the limiting rod 1184 extends above the coil 8, its lower surface is in close contact with the upper surface of the side of the coil 8 where the mounting clip 9 is installed. Then, when the height of the coil 8 is too high, the coil 8 transmits an upward force to the limiting rod 1184, causing the elastic element 117 to be driven to deflect the gripping cylinder upward by a certain angle. This ensures that the height of the gripping cylinder is always adapted to the mounting side of the coil 8 when the clip 9 is installed. When installing the clip 9, the height of the gripping cylinder can be automatically adjusted according to the actual situation to ensure that the clip 9 does not interfere with the coil 8 when placed, and its comb teeth 91 can accurately penetrate into the gap of the coil 8.

[0050] During operation, the clamps 9 manufactured by the mold are placed horizontally on conveyor belt I 101 in a consistent orientation. The comb teeth 91 of the clamps 9 are close to the surface of conveyor belt I 101, while the connecting handles 92 are transported away from the conveyor belt to the clamp 9 installation chamber of the coil 8. Above the end of conveyor belt I 101, there is a conveyor belt II 102. The sorting bar 1021 of conveyor belt II 102 cooperates with the connecting handles 92 of the clamps 9 to adjust their positions sequentially along the transmission direction via guide bars 105, causing them to fall onto the card storage assembly 103 connected to the end of conveyor belt I 101. The card storage plate 1031 moves along the transmission direction... The direction is tilted downwards, and the teeth 91 on the surface of the clip 9 all fall into the corresponding clearance grooves 10311. The connecting handle 92 is placed between the card storage plate 1031 and the limiting plate 1032, and the distance between the two is adapted to the thickness of the connecting handle 92, so that they fall down in an orderly manner without overlapping each other. When the clip 9 moves to the end of the card storage plate 1031, the motor drives the two delivery roller groups 104 to rotate at a certain angle in sequence. The delivery roller group 104 cooperates with the card loading unit 110 and rotates at a certain angle in sequence, driving the clips 9 in the card storage assembly 103 to move one by one to the bent part at the end of the card storage plate 1031.

[0051] Telescopic cylinder I 113 drives the tilting disc 115 to move up and down in a rotating manner; telescopic rack 114 first rises to the lowest point, that is, the tilting disc 115 moves to the highest position, at which time the two gripping arms 1182 of the gripping cylinder are arranged horizontally; then telescopic cylinder II 116 extends the gripping mechanism 118 towards the bent part, so that the positioning push block 1183 at the end of the telescopic rod 1181 fits tightly against the surface of the connecting handle 92 of the clamp 9; then the telescopic rod 1181 of the gripping mechanism 118 is controlled to retract and drive the gripping arms 1182 to clamp both ends of the clamp 9. Then telescopic cylinder II 116 drives the gripping cylinder to retract, causing the clamp 9 to disengage from the card storage assembly 103, and telescopic cylinder I 113 drives the gripping cylinder to move downward to the height adapted to the coil 8, and the gripping... The two gripping arms 1182 of the clamping cylinder are adjusted to be arranged vertically. Then, the telescopic cylinder II 116 extends and drives the gripping cylinder to move towards the coil 8. The lower surface of the limiting rod 1184 is in close contact with the top of the coil 8, which drives the gripping cylinder to move horizontally or upward at a certain angle towards the coil 8, so that the comb teeth 91 of the clip 9 accurately enter the gap between the coil 8. Then, the gripping cylinder is controlled to extend the telescopic rod 1181 and drive the gripping arm 1182 to release the clip 9. The extended telescopic rod 1181 drives the positioning push block 1183 at its end to continue to push the comb teeth 91 of the clip 9 to fully penetrate into the gap between the coil 8. Then, under the action of the telescopic cylinder I 113 and the telescopic cylinder II 116, the gripping cylinder returns to the initial position and continues to clamp the next clip 9 for installation work until the installation is completed.
