Detailed implementation manners

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0034] According to the concept of the present application, the embodiments of the temporary placement device for the heat exchange fin group after lamination are described herein in combination with Figures 1 to 5 Specifically, the temporary placement device for the heat exchange fin group is configured as a split structure, which has three components: a shaft core 5, a return spring 6, and a splicing plate 7. By utilizing the characteristic that the return spring 6 can automatically recover after deformation, the splicing plate 7 is rotated under pressure and then reset by the return spring 6 to always be between two adjacent heat exchange fins, separating the two adjacent heat exchange fins, thereby increasing the distance between the two adjacent heat exchange fins, facilitating the clamping device to grab, and avoiding damaging the heat exchange fins.

[0035] Please refer to Figures 1 to 5 , the temporary placement device for the heat exchange fin group after lamination includes: a shaft core 5, a return spring 6, and a splicing plate 7;

[0036] At least one return spring 6 is arranged on the outer side of the shaft core 5. One end of the return spring 6 is a fixed end, and the other end of the return spring 6 is a free end. The free ends of multiple return springs 6 are fixedly connected with splicing plates 7, and the upper end surfaces of multiple splicing plates 7 are on the same horizontal plane;

[0037] One side of the splicing plate 7 away from the return spring 6 is flat.

[0038] When the heat exchange fins are stacked, the splicing plate 7 is pressed downwards, so that multiple splicing plates 7 rotate along the central axis of the return spring 6;

[0039] The shaft core 5, the return spring 6 is slidably connected to the outer side of the shaft core 5, which is used to support and limit the position of the return spring 6, and the shaft core 5 is the rotation point of multiple splicing plates 7, which is beneficial to improving the smoothness of rotation.

[0040] The splicing plate 7 is clamped at the bottom ends of both sides of the heat exchange fin, and the splicing plate 7 is flat, so that the splicing plate 7 can be accurately inserted into the inner sides of two groups of heat exchange fins and can separate two adjacent groups of heat exchange fins.

[0041] Multiple return springs 6 are arranged to share the torsional force borne by each return spring 6, thereby improving the overall bearing capacity of the return spring, so that multiple heat exchange fins can be lifted through the splicing plate 7, thereby increasing the distance between two adjacent heat exchange fins, which is beneficial to improving the stability of the device.

[0042] Both ends of the return spring 6 are respectively fixed on the fixed plate 3 and the splicing plate 7. When the heat exchange fins are stacked, one side of the splicing plate 7 will be pressed, so that the splicing plate 7 forces the negative pressure spring 6 to undergo a torsional deformation. When the heat exchange fin completely passes through the splicing plate 7, the return spring 6 releases the elastic potential energy stored before and drives the splicing plate 7 to return to the horizontal state, so as to be clamped between the required heat exchange fins, and the distance between two adjacent groups of heat exchange fins is increased by the up and down movement of the splicing plate 7.

[0043] The shaft core 5 includes a support rod 51 and a fixing ring 52. Both ends of the support rod 51 are coaxially inserted with fixing rings 52. The fixing rings 52 at both ends are tightened on both sides of the support rod 51 by threads, and the fixing rings 52 are restricted at both ends of the support frame 31, so as to prevent the support rod 51 from axially sliding and improve the stability of the fixation between the shaft core 5 and the support frame 31.

[0044] A plurality of reset springs 6 are coaxially inserted outside the support rod 51, and the plurality of reset spring groups 6 are equidistantly distributed, which can improve the support of the reset springs 6 and prevent the heat exchange fins from slipping off the splicing plate 7. A support frame 31 is fixed outside the shaft core 5, and a fixing plate 3 is fixed on the side of the support frame 31 away from the shaft core 5. The fixing plate 3 is fixed to the shaft core 5 through the support frame 31, which can improve the stability between the fixing plate 3 and the shaft core 5. The support frame 31 is fixed at both ends of the shaft core 5, so that there is a gap for installing the reset springs 6 between the two support frames 31, avoiding interference between the reset springs 6 and the support frame 31 or the fixing plate 3 during movement. The upper end surface of the fixing plate 3 is welded to the fixed end of the reset spring 6 to improve the firmness of the connection between the two.

[0045] Nut seats 4 are fixed on both sides of the fixing plate 3. Inside the plurality of nut seats 4, lifting columns 2 are coaxially threadedly connected. Through the thread, a spiral drive is formed, enabling the nut seats 4 to move up and down along the lifting columns 2, which is beneficial for raising the splicing plate 7 and the heat exchange fins on the upper end of the splicing plate, increasing the distance between the heat exchange fins on both the upper and lower sides of the splicing plate 7, thus facilitating the precise grasping of the clamping device. The bottom of the lifting column 2 penetrates through a placement rack 1, and a sandwich layer is provided at the bottom of the placement rack 1. The transmission belt 21 is located inside the sandwich layer, and the transmission belt 21 is provided below the plurality of lifting columns 2. The plurality of lifting columns 2 form a synchronous rotation structure through the transmission belt 21. The synchronous transmission of the plurality of lifting columns 2 through the transmission belt 21 enables the plurality of nut seats 4 to lift synchronously, preventing the heat exchange fins from tilting. At the same time, a driven gear is provided at the bottom of one of the plurality of lifting columns 2, and a driving gear and a servo motor are engaged on the outside of the driven gear, which is the driving part of the device.

[0046] A fixing protrusion 71 is provided on one side of the splicing plate 7, and a mounting groove 72 is fixed on the other side of the splicing plate 7. The fixing protrusion 71 and the mounting groove 72 in adjacent two groups of splicing plates 7 are fitted together. By fitting the fixing protrusions 71 and the mounting grooves 72 in multiple splicing plates 7 together, the multiple splicing plates 7 are assembled, which is beneficial for the synchronous rotation of the multiple splicing plates 7 and improves the stability of the device.

[0047] A rubber pad 8 is bonded to the flat side of the multiple splicing plates 7 to increase the friction between the splicing plates 7 and the heat exchange fins, thereby preventing the heat exchange fins from slipping. At the same time, the rubber pad 8 can protect the heat exchange fins from being scratched by the sharp ends of the splicing plates 7. The separating device includes a fixing plate 3, nut seats 4, a shaft core 5, reset springs 6, and splicing plates 7. Multiple groups of the separating device are symmetrically arranged about the vertical center line of the placement rack 1. By simultaneously raising both sides of the heat exchange fins, it is beneficial to improve the stability of the device and enable it to be evenly lifted.

[0048] The following is a further description of the temporary placement device for the heat exchanger plate group after the plate stacking is completed, in conjunction with the accompanying drawings and implementation methods.

[0049] When in use, the support rod 51 is passed through multiple return springs 6 in sequence, and then the fixing ring 52 is tightened on both ends of the support rod 51. When in use, the superimposed unit presses the heat exchange plate on the top of the placement rack 1 and presses it down to make it fit. During the pressing process, the two sides of the heat exchange plate contact the splicing plate 7 and rotate it downward along the axis core 5 until the heat exchange plate completely passes through the splicing plate 7. At the same time, the rotation of the splicing plate 7 forces the return spring 6 to torsionally deform. When the heat exchange plate is completely separated from the splicing plate 7, the return spring 6 releases the elastic potential energy stored previously and drives The splicing plate 7 is restored to a horizontal state. When the clamping unit grabs the heat exchanger, the servo motor is started. The output end of the servo motor drives the driving gear to rotate. The driving gear meshes with the driven gear and drives the lifting column 2 to rotate. The multiple lifting columns 2 rotate simultaneously through the transmission belt 21. The lifting column 2 drives the multiple partitions to move upward along the lifting column 2 through the nut seat 4. At this time, the rubber pad 8 on the outside of the splicing plate 7 contacts the side wall of the heat exchanger and drives the heat exchanger to rise during the rising process of the partition, thereby increasing the interval between the heat exchangers on the upper and lower sides of the splicing plate 7.
