Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger plate stacking, and more specifically, to a transformer heat exchanger plate stacking device. Background Art

[0002] The main function of the transformer heat exchanger is to help the transformer dissipate heat and ensure that it operates at a safe temperature. The heat generated inside the transformer can be transferred to the external environment through the heat exchanger to prevent the transformer from being damaged due to overheating.

[0003] When the heat exchanger is officially used, two heat exchangers need to be welded together, and then welded to the upper and lower oil collecting pipes to form an overall heat dissipation structure. Therefore, after the production of a single heat exchanger is completed, it is necessary to stack it first to facilitate the subsequent welding of the two heat exchangers.

[0004] Although the existing palletizing device can realize the stacking and palletizing of different workpieces, the heat sink structure is different from that of ordinary workpieces. The heat sink is not only provided with a three-dimensional groove structure for heat dissipation, but also provided with an arc-shaped docking interface for welding with the oil collecting pipe. On the one hand, due to the special structure of the heat sink itself, the heat sink is easily displaced due to direct contact with the conveying roller during the conveying process; on the other hand, when the heat sink is docked with the palletizing device after the heat sink is transported, if the heat sink is displaced, the position of the heat sink after entering the palletizing device will be inaccurate. If a manipulator is used to grab the heat sink at different points for welding, it will further cause deviations in the welding points between the heat sink and the oil collecting pipe, which will not only affect the heat dissipation performance of the heat sink, but may also cause leakage of the oil collecting pipe. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a transformer heat exchanger stacking device that is equipped with a tray and a gasket for placing the heat sink, which protects the heat sink and prevents the heat sink from shifting during transportation. A pushing assembly is provided to ensure that the heat sink and the stacking device are accurately docked, and the stacking points of the heat sink are consistent during the stacking process, so as to avoid affecting the subsequent heat dissipation performance of the heat sink.

[0006] To achieve the above object, the present invention provides the following technical solutions: A heat exchanger stacking device for a transformer comprises a conveying assembly, a stacking assembly abutting against the conveying assembly, a pushing assembly arranged on the conveying assembly, and a heat sink tray placed on the conveying assembly, wherein the conveying assembly comprises a conveying frame and a plurality of conveying rollers arranged on the conveying frame, the heat sink tray comprises a tray seat placed on the top of the conveying frame and a pad placed inside the tray seat, a heat sink can be placed inside the pad, the pushing assembly is symmetrically arranged in two groups with respect to the conveying frame, and each group of the pushing assembly comprises pushing pieces arranged on both sides of the tray seat.

[0007] The present invention is further configured as follows: a placement groove is provided inside the tray seat, the placement groove is configured as a rectangular structure, and a fitting portion is provided on one side of the placement groove close to the top of the pushing platform.

[0008] The present invention is further configured as follows: a placement portion whose shape matches that of the placement groove is provided at the bottom of the pad, and engaging plates whose shape matches that of the engaging portion are provided at both sides of the pad.

[0009] The present invention is further configured as follows: a matching groove whose shape matches the shape of the heat sink is opened inside the pad, and a group of positioning columns are respectively arranged at both ends of the matching groove.

[0010] By adopting the above technical solution, when the heat sink is placed inside the pad, the three-dimensional groove on the heat sink fits with the matching groove, and the arc-shaped interface on the heat sink fits with the positioning column. On the one hand, it can ensure that the heat sink fits tightly with the pad, and the pad is used to provide a buffer to reduce the probability of damage caused by bumps during transportation and stacking; on the other hand, the positioning columns at both ends fit with the arc-shaped interface on the heat sink to limit the heat sink, and at the same time, it can prevent the heat sink from shifting during subsequent transportation and stacking.

[0011] The present invention is further configured as follows: each group of the pushing components also includes a pushing platform arranged on a side of the conveying frame close to the stacking component, and the pushing platform is provided with a guide rail, and the guide rail is arranged along the length direction of the conveying frame.

[0012] The present invention is further configured as follows: an adjusting cylinder is arranged on the top of the guide rail, the adjusting cylinder is arranged along the width direction of the conveyor frame, the pusher is installed on the adjusting cylinder, and a fitting groove whose shape matches the shape of the tray seat is opened on its side wall.

[0013] By adopting the above technical solution, during the process of the conveying roller conveying the pallet seat, the cylinder is adjusted to move along the width direction of the conveying frame, so that the engaging grooves on the two sets of pushers on both sides of the pallet seat are respectively engaged with the side walls of the pallet seat, thereby limiting the position of the pallet seat. After the limiting is completed, the position of the pallet seat is adjusted by continuing to move the pushers along the width direction of the conveying frame. After the adjustment is completed, the pushers are synchronously driven by the guide rail to move toward the stacking assembly, thereby ensuring that the pallet seat is accurately positioned before entering the stacking assembly.

[0014] The present invention is further configured as follows: the stacking assembly includes a base, a cylinder arranged at the center of the top of the base, and mounting frames arranged on both sides of the top of the base, a loading platform is installed on the top of the cylinder, and multiple groups of stacking frames are installed on the side walls of the two groups of mounting frames in the vertical direction.

[0015] The present invention is further configured as follows: each group of the stacking racks includes a connecting rod and a limiting rod arranged on the mounting frame, a rotating member sleeved on the connecting rod, and a limiting member installed on the rotating member, the rotating members are symmetrically arranged in two groups about the connecting rod, and a limiting groove is arranged on each group of the limiting members.

[0016] The present invention is further configured as follows: a loading assembly is provided on one side of the conveying assembly, the loading assembly includes a loading platform and a base installed on the top of the loading platform, a first rotating shaft is rotatably installed on the base, and a second rotating shaft is rotatably installed on one end of the first rotating shaft away from the base.

[0018] The beneficial effects of the present invention are: By setting a pallet seat and a pad, the heat sink after processing is placed inside the pad for subsequent transportation and stacking. This not only makes it easy to use the pallet seat to transport and stack the heat sink, but also avoids collisions between the heat sink and rigid materials. Pushing components are set on both sides of the pallet seat, so that the pallet seat can be limited and the position can be adjusted by pushing parts, which facilitates accurate docking between the pallet seat and the stacking component, reduces the probability of inconsistent positions of different heat sinks entering the stacking component due to inaccurate positioning of the pallet seat, and further causes changes in the subsequent welding and material collection points. The accuracy of the final welding point is guaranteed, thereby effectively avoiding the reduction of the heat dissipation performance of the heat sink and the leakage of the oil collecting pipe.

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basics of the present invention in an illustrative manner, so it only shows the composition related to the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Please refer to Figure 1-2 The transformer heat exchanger stacking device includes a conveying component 2, a loading component 1 arranged on one side of the conveying component 2, a stacking component 3 abutting against the conveying component 2, a pushing component 4 arranged on the conveying component 2, and a heat sink tray 5 placed on the conveying component 2. The loading component 1 can load the heat sink 6 and place it inside the heat sink tray 5, and the conveying component 2 drives the heat sink tray 5 and the heat sink 6 to be transported to the stacking component 3. During the conveying process, the pushing component 4 guides and limits the heat sink tray 5 from both sides of the heat sink tray 5 to ensure that the heat sink tray 5 can be accurately docked with the stacking component 3. After the heat sink tray 5 enters the stacking component 3, the stacking component 3 stacks the heat sink tray 5 and the heat sink 6 one by one.

[0035] Please refer to Figure 1 and Fig.12 The loading assembly 1 includes a loading platform 11 arranged on one side of the conveying assembly 2, and the height of the loading platform 11 is adapted to the height of the conveying assembly 2. A base 12 is installed on the top of the loading platform 11, and a first rotating shaft 13 is rotatably installed on the base 12. The first rotating shaft 13 can rotate relative to the base 12. A second rotating shaft 14 is rotatably installed at one end of the first rotating shaft 13 away from the base 12, and the second rotating shaft 14 can rotate relative to the first rotating shaft 13. A loading tray 15 is rotatably installed at one end of the second rotating shaft 14 away from the first rotating shaft 13, and the loading tray 15 can rotate relative to the second rotating shaft 14. By rotating the first rotating shaft 13 relative to the base 12, the second rotating shaft 14 relative to the first rotating shaft 13, and the loading tray 15 relative to the second rotating shaft 14, the loading tray 15 can be changed in various directions and angles, and finally the loading of the heat sink 6 is realized. The loading tray 15 is set as a rectangular frame structure whose shape is adapted to the heat sink 6, and a plurality of groups of material taking suction cups 16 are arranged on the loading tray 15. After the heat sink 6 is processed, the loading tray 15 is moved to the position of the heat sink 6, and the heat sink 6 is sucked by the material taking suction cup 16 to avoid damage to the heat sink 6 during the loading process.

[0036] Please refer to Figure 1 and Fig. 9The conveying assembly 2 includes a conveying frame 21 and a plurality of conveying rollers 22 arranged on the conveying frame 21. The height of the conveying frame 21 is adapted to the height of the loading platform 11, and a plurality of conveying rollers 22 are rotatably mounted inside the conveying frame 21. The plurality of conveying rollers 22 are arranged along the length direction of the conveying frame 21, and each group of conveying rollers 22 can rotate relative to the conveying frame 21, and the heat sink tray 5 can be conveyed by the rotation of the conveying rollers 22.

[0037] Please refer to Figure 1-3 The heat sink tray 5 includes a tray seat 51 placed on the top of the conveyor frame 21 and a pad 52 placed inside the tray seat 51. The pad 52 is made of a flexible material to provide buffering protection for the heat sink 6. It should be noted that the material of the pad 52 can be a flexible material well known to those skilled in the art, and this application does not make any specific restrictions. The tray seat 51 is configured as a rectangular structure, and a placement groove 511 is provided inside the tray seat 51. The placement groove 511 is configured as a rectangular structure. A fitting portion 512 is provided on one side of the placement groove 511 close to the top of the pushing platform 41, and the fitting portion 512 is configured as a rectangular structure with an area larger than the placement groove 511. A placement portion 521 whose shape matches the shape of the placement groove 511 is provided at the bottom of the pad 52. When the pad 52 is placed inside the tray seat 51, the placement portion 521 fits with the placement groove 511. The backing plate 52 is provided with a fitting plate 522 whose shape matches the fitting part 512 on both sides. When the backing plate 52 is placed inside the tray seat 51, the fitting plate 522 fits with the fitting part 512. The heat sink 6 can be placed inside the backing plate 52. The heat sink 6 is provided with multiple groups of three-dimensional grooves for heat dissipation. A group of arc-shaped docking interfaces for welding with the oil collecting pipe are provided at both ends of the heat sink 6. A matching groove 524 whose shape matches the three-dimensional groove on the heat sink 6 is provided inside the backing plate 52. The size of the matching groove 524 matches the shape of the heat sink 6. A group of positioning columns 523 are provided at both ends of the matching groove 524. The shape and position of the positioning columns 523 are both adapted to the arc-shaped docking interface on the heat sink 6. When the heat sink 6 is placed inside the backing plate 52, the three-dimensional groove on the heat sink 6 fits with the fitting groove 524, and the arc-shaped docking interface on the heat sink 6 fits with the positioning columns 523. On the one hand, it can ensure that the heat sink fits tightly with the pad 52, and the pad 52 is used to provide a buffer to reduce the probability of damage caused by bumps during transportation and stacking; on the other hand, the positioning columns 523 at both ends can fit with the arc-shaped docking interface on the heat sink 6 to limit the heat sink 6, and at the same time, it can prevent the heat sink 6 from shifting during subsequent transportation and stacking. An inclined wall 525 is also provided at the edge in the length direction of the interlocking plate 522. If there is an error in the position when the feeding component 1 places the heat sink 6, resulting in the heat sink 6 not being accurately placed in the matching groove 524, the heat sink 6 can also slide freely along the inclined wall 525 on the interlocking plate 522 to the inside of the matching groove 524 to ensure the accuracy of the placement of the heat sink 6.

[0038] Specifically, by providing a pallet seat 51 and a pad 52, the processed heat sink 6 is placed inside the pad 52 for subsequent transportation and stacking. This not only makes it easy to use the pallet seat 51 to transport and stack the heat sink 6, thereby avoiding collisions between the heat sink 6 and rigid materials, but also allows the pad 52 to provide cushioning and protection for the heat sink 6, further reducing the probability that the heat sink 6 will be damaged by collisions during transportation and stacking, thereby affecting the subsequent heat exchange performance.

[0039] Please refer to Figure 1-2 and Figure 9-11 The pusher assembly 4 is symmetrically arranged into two groups about the conveyor frame 21, and each group of pusher assembly 4 includes a pusher platform 41 arranged on the side of the conveyor frame 21 close to the stacking assembly 3. The pusher platform 41 is installed on the top of the conveyor frame 21, and the pusher platform 41 is arranged along the length direction of the conveyor frame 21. A guide rail 42 is arranged on the pusher platform 41, and the guide rail 42 is arranged along the length direction of the conveyor frame 21. A driving member is arranged inside the guide rail 42 to drive the guide rail 42 to slide. The type and driving mode of the driving member inside the guide rail 42 are technical means well known to those skilled in the art, and this application will not be described in detail here. An adjusting cylinder 43 is arranged on the top of the guide rail 42, and the adjusting cylinder 43 can move synchronously with the guide rail 42. The adjusting cylinder 43 is arranged along the width direction of the conveyor frame 21, and the adjusting cylinder 43 can be telescoped along the width direction of the conveyor frame 21. A pusher 44 is installed on the top of the adjusting cylinder 43, and the pusher 44 can move synchronously with the adjusting cylinder 43. The pusher 44 is arranged along the width direction of the conveyor frame 21 and is arranged on the side of the regulating cylinder 43 close to the center of the conveyor frame 21. The side wall of the pusher 44 is provided with an engaging groove 45 whose shape matches the shape of the tray seat 51. The shape of the engaging groove 45 matches the shape of the side wall of the tray seat 51, and the tray seat 51 can be limited from both sides thereof.

[0040] Specifically, during the process of the conveying roller 22 conveying the pallet seat 51, the regulating cylinder 43 is extended and retracted to drive the pusher 44 to move along the width direction of the conveying frame 21, so that the engaging grooves 45 on the two groups of pushers 44 on both sides of the pallet seat 51 are respectively engaged with the side walls of the pallet seat 51, thereby limiting the position of the pallet seat 51. After the limiting is completed, the position of the pallet seat 51 is adjusted by continuing to move the pusher 44 along the width direction of the conveying frame 21. After the adjustment is completed, the pusher 44 is synchronously driven by the guide rail 42 to move toward the direction of the stacking assembly 3, thereby ensuring that the pallet seat 51 is accurately positioned before entering the stacking assembly 3. By arranging the pushing assembly 4 on both sides of the pallet seat 51, the pushing piece 44 is used to limit and adjust the position of the pallet seat 51, so as to facilitate the accurate docking of the pallet seat 51 with the stacking assembly 3, and reduce the probability of inconsistent positions of different heat sinks 6 after entering the stacking assembly 3 due to inaccurate positioning of the pallet seat 51, and further causing changes in the subsequent welding and material taking points, thereby ensuring the accuracy of the final welding point, thereby effectively avoiding the reduction of the heat dissipation performance of the heat sink and the occurrence of oil collecting pipe leakage.

[0041] Please refer to Figure 1-2 and Figure 5-8 The stacking assembly 3 includes a base 31 and mounting frames 32 arranged on both sides of the top of the base 31. The two groups of mounting frames 32 are symmetrically arranged, and the side walls are respectively abutted against the conveying frame 21. A cylinder 33 is arranged at the center of the top of the base 31, and the cylinder 33 can be telescoped in the vertical direction. A loading platform 34 is installed on the top of the cylinder 33, and the telescope of the cylinder 33 can drive the loading platform 34 to move synchronously in the vertical direction. The loading platform 34 is arranged horizontally, and the loading platform 34 is arranged as a rectangular structure adapted to the shape of the pallet seat 51, and the pallet seat 51 can be placed on the top of the loading platform 34. Multiple groups of stacking frames 35 are installed on the side walls of the two groups of mounting frames 32 in the vertical direction, and the two groups of stacking frames 35 are arranged equidistantly. The pallet seat 51 placed on the top of the loading platform 34 can be moved upward to different positions of the stacking frames 35 under the drive of the cylinder 33 to complete the stacking.

[0042] Please refer to Figure 1-2 and Figure 5-8Each stacking rack 35 includes a connecting rod 351 and a limiting rod 355 arranged on the mounting rack 32. Both ends of the connecting rod 351 and the limiting rod 355 penetrate the mounting rack 32. The connecting rod 351 is arranged on the mounting rack 32 near the center of the stacking assembly 3. A rotating member 352 is sleeved on the connecting rod 351. The rotating members 352 are symmetrically arranged in two groups about the connecting rod 351. Each group of rotating members 352 can rotate around the connecting rod 351. A group of limiting members 353 is installed on each group of rotating members 352. The limiting members 353 can rotate synchronously with the rotating members 352. During the rotation of the limiting members 353, they can also abut against the bottom of the limiting rod 355, so that the limiting members 353 are limited by the limiting rod 355. The spacing between the two groups of limiting members 353 is adapted to the width of the tray seat 51, so that the tray seat 51 is placed between the two groups of limiting members 353. A limiting groove 354 is provided on each group of limiting members 353. The limiting groove 354 is provided on the side of the limiting member 353 close to the center of the stacking assembly 3. The side wall of the pallet seat 51 is provided with a structure whose shape is adapted to the limiting groove 354. When the pallet seat 51 is placed on the top of the limiting groove 354, it can be engaged with the limiting groove 354, thereby limiting the pallet seat 51.

[0043] Specifically, after a group of pallet seats 51 are transported to the top of the loading platform 34, the cylinder 33 drives the loading platform 34 upward, so that the mobile pallet seat 51 moves to the position of a group of stacking racks 35. As the mobile pallet seat 51 continues to rise, the two sides of the mobile pallet seat 51 respectively abut against the side walls of the two groups of limit members 353, so that the limit members 353 are forced to rotate, leaving enough space for the pallet seat 51 to rise. When the pallet seat 51 rises to the top of the stacking rack 35, the limit members 353 are not affected by external forces at this time, and reset under the action of their own weight, and rotate to the state where the limit members 353 abut, and the limit members 353 are in a horizontal state, and then the cylinder 33 drives the loading platform 34 to descend, and the pallet seat 51 loses support and moves downward to fit into the limit groove 354 on the limit member 353, and the limit member 353 is used to provide support for the pallet seat 51, so that the pallet seat 51 is supported on the top of the limit member 353 to complete the stacking. Repeat the above operation to complete the stacking of multiple groups of pallet seats 51.
