Description

Technical Field

[0001] The present invention belongs to the field of heat exchange plate processing, and particularly relates to a device for transferring a heat exchange plate group after lamination to a pressing station. Background Art

[0002] The 19 heat exchanger plates are stacked into groups in a certain order by the stacking machine, and the stacked heat exchanger plate groups are safely and accurately moved from the stacking workstation to the pressing station.

[0003] For example, the heat exchanger fin picking device and heat exchanger fin transfer equipment with application number CN202010071880.7 fixes a slide rail and a screw at the bottom of the picking device, and drives the picking device and the heat exchanger fin to move to the pressing station through the screw. In order to avoid the direction and position of the heat exchanger fin being offset, the transfer device is moved to the pressing station together with the heat exchanger fin group. When the press is pressed down, force is applied to the heat exchanger group and the transfer plate together. The bottom support of the guide rail is weak and is under pressure for a long time, resulting in bending and deformation at the connection between the bottom screw and the guide rail bracket, and the moving position of the picking device deviates, so that it cannot be accurately moved to the pressing station.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] According to the concept of this application, Figures 1 to 7 To describe an embodiment of a device for transferring a heat exchange plate group to a press-fitting station after the lamination is completed. Specifically, the device for transferring a heat exchange plate group to a press-fitting station after the lamination is completed is constructed as a split structure, which has three components, namely a transfer platform 1, a nut seat 2 and a rotating platform 3. By arranging the nut seat 2 on both sides of the transfer platform 1, the force direction of the nut seat 2 is non-vertical, which can reduce the pressure on the nut seat 2, thereby preventing the nut seat 2 from bending and deforming, and improving the accuracy of the movement of the transfer platform 1. At the same time, the roller 4 at the bottom of the rotating platform 3 absorbs the pressure on the rotating platform 3, which can reduce the displacement distance between the gear 32 and the servo motor 9 during the downward pressing process of the press, thereby reducing the wear between the parts during each pressing, which is beneficial to improving the service life of the device.

[0037] Please refer to Figures 1 to 7 , a device for transporting the completed heat exchange plate group to the press-fitting station, comprising: a nut seat 2, a gear 32 and a roller 4;

[0038] At least one nut seat 2 is fixed on both sides of the transfer platform 1, and a driving screw 21 is connected to the inner side of the nut seat 2. At least one annular groove 11 is opened on the upper end surface of the transfer platform 1, and a rotating platform 3 is inserted into the upper end surface of the transfer platform 1.

[0039] At least one roller 4 is evenly spaced inside the plurality of annular grooves 11, and the transfer platform 1 forms a rotating structure with the rotating platform 3 through the plurality of rollers 4, and gear teeth 32 are fixed on the outer wall of the rotating platform 3;

[0040] The outer wall of the gear teeth 32 is connected to the servo motor 9 via a bevel gear.

[0041] The transfer platform 1 bears the pressure of the press machine. Since the nut seats 2 are located on both sides of the transfer platform 1, the nut seats 2 do not directly bear the vertical pressure, thereby reducing the pressure on the nut seats 2 and preventing the nut seats 2 from bending and deforming, which is beneficial to improving the movement accuracy of the transfer platform 1.

[0042] The rotating table 3 is directly inserted into the inner side of the transfer table 1 through the annular groove 11. At this time, the lower end surface of the rotating table 3 is in contact with the upper end of the transfer table 1, and at the same time, the bottom surface of the annular groove 11 is in contact with the roller 4. Since the gap between the rotating table 3 and the transfer table 1 is small, it is difficult for the position of the rotating table 3 to shift when the rotating table 3 is pressed, thereby reducing the wear between the servo motor 9 and the gear 32 during each press-fitting, which is beneficial to increasing the service life of the device.

[0043] At least one mounting hole 12 is equidistantly formed on the side walls of the plurality of annular grooves 11, and fixed shafts 41 are coaxially provided at both ends of the plurality of rollers 4, and the plurality of rollers 4 are fixed on the inner sides of the mounting holes 12 by the fixed shafts 41, so as to limit the positions of the rollers 4 and avoid mutual interference between the plurality of rollers 4 when the rotating table 3 rotates, which is beneficial to improving the stability of the device. At least one annular protrusion 31 is coaxially fixed to the lower end surface of the rotating table 3, and the annular protrusion 31 rotates in the annular groove 11, so as to limit the position of the rotating table 3, and the lower end surfaces of the plurality of annular protrusions 31 are tangent to the outer walls of the rollers 4. When the rotating table 3 rotates, the lower end surface of the annular protrusion 31 rotates on the rollers 4, which can reduce the friction between the two and is beneficial to improving the stability of the rotation.

[0044] A buffer pad 5 is coaxially arranged on the upper end surface of the turntable 3, and a flange ring 51 is arranged around the bottom of the outer wall of the buffer pad 5, and the flange ring 51 is connected to the turntable 3 by bolts. The buffer pad 5 is fixed above the turntable 3 by bolts and the flange ring 51, and the buffer pad 5 is made of a buffer material such as rubber or foam, which is used to absorb and mitigate the impact force and reduce vibration when the press is pressed down.

[0045] The upper end surface of the support seat 6 is fixed with multiple groups of buffer components, and the buffer components include a hydraulic rod 7, a support spring 71 and a fixed plate 72. The fixed plate 72 is used to limit the position of the fixed plate 8. The upper end surface of the mounting ring 61 is coaxially fixed with the hydraulic rod 7, and the outer wall of the hydraulic rod 7 is fixed with the support spring 71. Two fixed plates 72 are fixed to the upper end of the support spring 71, which are used to support the fixed plate 8 through the hydraulic rod 7, so that the fixed plate 8 can drive the hydraulic rod 7 to compress the support spring 71 when under pressure.

[0046] A fixed disk 8 is provided through the upper ends of multiple hydraulic rods 7, and a heat exchange plate 10 is placed above the fixed disk 8. A support seat 6 is bolted to the upper end surface of the rotating table 3, and at least one mounting ring 61 is provided on the upper end surface of the support seat 6. Multiple buffer assemblies are fixed between the rotating table 3 and the fixed disk 8 through the support seat 6, so that the buffer assemblies rotate synchronously with the rotating table 3. Multiple groups of buffer assemblies are symmetrically arranged about the vertical center line of the fixed disk 8, and the heat exchange plate 10 is clamped between the multiple groups of hydraulic rods 7, and the multiple hydraulic rods 7 are tangent to the edge of the heat exchange plate 10. The heat exchange plate 10 is pressed against by the hydraulic rod 7 to limit the position of the heat exchange plate 10 and prevent the heat exchange plate 10 from shifting during movement.

[0047] A protective shell 91 is installed on the outside of the output end of the servo motor 9 to protect the gear set and reduce the exposed area, which is beneficial to increasing the practical life of the gear. The upper end surface of the transfer platform 1 and the lower end surface of the rotating table 3 are coated with lubricant. The lubricating oil reduces the friction between the transfer platform 1 and the rotating table 3, which can reduce energy loss and wear between the two.

[0048] The following is a further description of the device for transferring the completed heat exchange plate group to the pressing station provided by the utility model in combination with the accompanying drawings and implementation modes.

[0049] When in use, the heat exchange plate group after lamination is placed on the fixed disk 8 and clamped between multiple groups of buffer components, and the driving screw 21 is started. The driving screw 21 drives the nut seat 2 and the transfer platform 1 to slide horizontally along the central axis of the screw until they move to the bottom of the pressing station. When the bevel gear at the output end of the servo motor 9 is started and meshed with the gear teeth 32, the rotating table 3 is driven to rotate. At the same time, the lower end surface of the annular protrusion 31 drives multiple rollers 4 to rotate synchronously through friction until they stop after rotating to a certain angle. At this time, the pressing device presses the heat exchange plate 10 downward, and the heat exchange plate 10 squeezes the fixed disk 8 downward. At this time, the fixed disk 8 moves downward to squeeze the fixed plate 72 and the buffer pad 5. The fixed plate 72 compresses the hydraulic rod 7 and the support spring 71, and the potential energy transmitted by the fixed disk 8 is absorbed by the buffer pad 5 and the support spring 71, thereby reducing the pressure transmitted to the transfer platform 1 by the pressing device. When the pressing is completed, the driving screw 21 is reversed to move the transfer platform 1 to the working station.
