Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to a heat exchanger production line and a method for producing heat exchangers. Background Technology

[0002] In air conditioning, the two components refer to the evaporator and the condenser, both of which are heat exchangers that perform evaporation, heat dissipation, and heat exchange, and are important parts of the refrigeration system. One existing heat exchanger manufacturing process involves machining the heat exchanger body, including the fins, on a punch press. Workers then remove the heat exchanger body and transfer it to a buffer area for stacking and storage. During production, workers use a material cart to transfer the heat exchanger bodies from the buffer area to a tube-threading fixture for manual tube threading. This processing method has the following disadvantages: workers need to prepare copper tubes, side plates, heat exchangers, and other materials in advance before threading; material preparation is time-consuming and labor-intensive, and storage space needs to be reserved for materials; after each heat exchanger is processed, workers need to bend over to pick it up and lift it to stack it, resulting in a large amount of inefficient handling and significantly reducing production efficiency.

[0003] Therefore, it is necessary to improve the production method of this heat exchanger to overcome the shortcomings of the existing technology. Summary of the Invention

[0004] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a heat exchanger production line that can save on material transfer procedures during heat exchanger production, improve heat exchanger production efficiency, and thus improve enterprise benefits.

A stacking mechanism is provided at the inlet end of the first conveyor line, and a stacking mechanism is provided at the outlet end. The stacking mechanism includes a lifting conveyor, a stacking drive, and a stacking baffle. The lifting conveyor is located on one side of the outlet end of the first conveyor line, the stacking drive is located above the lifting conveyor, and the stacking baffle is fixed to the output end of the stacking drive.

[0047] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0048] In air conditioning, the two components refer to the evaporator and the condenser, both of which are heat exchangers that perform evaporation, heat dissipation, and heat exchange, and are important parts of the refrigeration system. In a current heat exchanger manufacturing process, the heat exchanger body, including the fins, is machined on a punch press. Workers then remove the heat exchanger body and transfer it to a buffer area for stacking and storage. During production, workers use a material cart to transfer the heat exchanger bodies from the buffer area to a tube-threading fixture for manual tube threading. This processing method has the following disadvantages: workers need to prepare copper tubes, side plates, heat exchangers, and other materials in advance before threading; material preparation is time-consuming and labor-intensive, and storage space needs to be reserved for materials; after each heat exchanger is processed, workers need to bend over to pick it up and lift it to stack it, resulting in a large amount of inefficient handling and significantly reducing production efficiency. Therefore, this application provides a heat exchanger production line.

[0050] like Figures 1-7 As shown in the figure, this embodiment provides a heat exchanger 7 production line, which includes a first conveyor line 3; a stacking mechanism 2 is provided at the inlet end of the first conveyor line 3, and a stacking mechanism 4 is provided at the outlet end of the first conveyor line 3. The stacking mechanism 2 includes a lifting conveying device, a stacking drive device 22, and a stacking baffle 26. The lifting conveying device is located on one side of the outlet end of the first conveyor line 3, the stacking drive device 22 is located above the lifting conveying device, and the stacking baffle 26 is fixed to the output end of the stacking drive device 22. The stacking drive device 22 drives the stacking baffle 26 to push the heat exchanger 7 onto the lifting conveying device.

[0051] In this production line, the stamped heat exchangers 7 are stacked into a pile and sent to the entrance of the first conveyor line 3. The unpacking mechanism 2 separates the heat exchangers 7 one by one, allowing them to enter the first conveyor line 3 individually. Workers thread the tubes through the heat exchangers 7 on both sides of the first conveyor line 3. The threaded heat exchangers 7 are then sent out by the first conveyor line 3 and stacked into a pile by the stacking mechanism 4 before entering the next process. This production line uses the unpacking mechanism 2 to load the heat exchangers 7 and the stacking mechanism 4 to unload them. The coordinated operation of these mechanisms saves on material transfer procedures during the heat exchanger production process, improves the production efficiency of the heat exchangers 7, and thus increases the company's profits.

[0057] Specifically, the heat exchangers 7 are stacked in piles for feeding. After each heat exchanger 7 enters the first conveyor line 3, the height of the remaining heat exchangers 7 will decrease. At this time, the second conveyor line 214 needs to be lowered for targeted adjustment.

[0058] During the feeding process, the dismantling drive device 22 drives the dismantling baffle 26 to push the heat exchanger 7 to the second conveyor line 214. Then, the second conveyor line 214 rises and falls until it reaches a position flush with the surface of the first conveyor line 3, at which point it starts, allowing the heat exchanger 7 to enter the first conveyor line 3. More preferably, a correction baffle for adjusting the position of the heat exchanger 7 is provided at the inlet of the second conveyor line 214.

[0158] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0159] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0160] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
