[0035] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] The heat exchanger is one of the core components of an air conditioner, consisting of aluminum foil and copper tubing. In the production process, the aluminum foil rolls are first punched into fins using a punch press, and then the fins are placed on a tube-threading table. The entire process requires manual handling, resulting in high labor intensity and low production efficiency. Furthermore, the fins are only 0.1mm thick, and due to the special dimensions of the fin material, "folded" fins frequently occur, requiring manual straightening and further reducing production efficiency.

[0037] Based on this, in order to solve the problem of low production efficiency caused by relying on manual correction and turnover of heat exchanger fins in the existing technology, this utility model provides a destacking and conveying device with correction function.

[0038] Please refer to the following: Figures 1 to 8 The destacking and conveying device with correction function provided by this utility model includes:

[0039] Support frame 1;

[0040] The feeding platform 2 is movably mounted on the support frame 1 and is used to carry the multi-layer heat exchanger fins from the previous process.

[0041] The bidirectional hierarchical feeding assembly includes a longitudinal lifting mechanism 3 and a transverse pushing mechanism 4. The longitudinal lifting mechanism 3 drives the feeding platform 2 carrying the heat exchanger fins to rise multiple times according to the number of heat exchanger fin layers. The transverse pushing mechanism 4 pushes the uppermost heat exchanger fins to the next process after each rise of the feeding platform 2.

[0042] The straightening mechanism 5 is fixed on the support frame 1 and is used to straighten the shape of the heat exchanger fins during the process of the transverse pushing mechanism 4 pushing the heat exchanger fins.

[0043] The advantage of this design is that the present invention utilizes a longitudinal lifting mechanism 3 to lift the loading platform 2 in stages. This ensures that after each ascent, the uppermost heat exchanger fins carried by the loading platform 2 reach the pushing position, whereupon the uppermost heat exchanger fins are pushed by the transverse pushing mechanism 4. During this process, a straightening mechanism 5 corrects the shape of the heat exchanger fins, ensuring that each layer of heat exchanger fins is transferred to the next process after correction. Therefore, the present invention, through the cooperation of the longitudinal lifting mechanism 3, the transverse pushing mechanism 4, and the straightening mechanism 5, achieves automatic unstacking, straightening, and transfer of heat exchanger fins, greatly reducing the labor intensity of workers and significantly improving production efficiency.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the straightening mechanism 5 is a blade, which has a comb-like part 51 that fits into the heat exchanger fins.

[0045] The advantage of this design is that during the process of the transverse pushing mechanism 4 pushing the heat exchanger fins, the comb-tooth part 51 of the blades comes into contact with the heat exchanger fins to restore the fallen fins to their original shape. This achieves automatic correction of the heat exchanger fins during the pushing process, effectively solving the problem of manually repairing the fallen fins and significantly improving production efficiency.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the blade is fixed to the support frame 1 by the first fastener, and the blade has a U-shaped adjustment hole 52 for the first fastener to pass through.

[0047] The advantage of this design is that the blade and the support frame 1 are fixedly connected by the first fastener (such as bolts), which is convenient to operate; at the same time, the blade is provided with a U-shaped adjustment hole 52 so that the fixed position of the blade can be adjusted, and the debugging is also very convenient. This ensures that the blade can be perpendicularly attached to the top of the heat exchanger fins at 90° during the feeding process, thereby ensuring the automatic correction effect.

[0048] In some embodiments of this invention, the blade is made of alloy tool steel.

[0049] The advantage of this design is that the blades are made of alloy tool steel, which is not easily deformed and has a long service life. For example, the blades are made of Cr12 steel, a high-carbon, high-chromium alloy tool steel with excellent wear resistance, compressive strength, and micro-deformation ability. Compared with general low-alloy tool steel, Cr12 steel has 3 to 4 times higher wear resistance.

[0050] In addition, the application of laser surface hardening technology on the blade surface results in minimal deformation, high wear resistance, and can significantly extend the blade's service life.

[0051] In some embodiments of this utility model, such as Figure 3 , Figure 4 As shown, the longitudinal lifting mechanism 3 includes multiple lead screws 31 spaced apart on the support frame 1, multiple transmission sprockets 32 fixed to the bottom of the lead screws 31 one by one, a drive sprocket 33 connected to the multiple transmission sprockets 32 by a chain, and a motor 34 that drives the drive sprocket 33 to rotate. Support sliders 35 that jointly support the loading platform 2 are provided on the multiple lead screws 31.

[0052] It should be noted that the number of lead screw 31, transmission sprocket 32 ​​and support slider 35 are the same, preferably four. The motor 34 is a servo motor 34, which has the advantages of high control precision, fast response speed and stable low-speed operation.

[0053] The advantage of this design is that the motor 34 drives the drive sprocket 33 to rotate, which in turn drives the transmission sprocket 32 ​​and the lead screw 31 to rotate, allowing the support slider 35 and the feeding platform 2 to move longitudinally along the lead screw 31. When the rotation direction of the motor 34 is different, the feeding platform 2 can reciprocate up and down longitudinally along the lead screw 31. Therefore, the longitudinal lifting mechanism 3 has a simple structure and is easy to operate. The longitudinal lifting mechanism 3 lifts the feeding platform 2 in stages, ensuring that each layer of heat exchanger fins accurately reaches the pushing position.

[0054] In some embodiments of this utility model, such as Figure 5 , Figure 6 As shown, the transverse pushing mechanism 4 includes a pair of slide rails 41 spaced apart on the support frame 1, a movable frame 42 movably disposed between the pair of slide rails 41, and a cylinder 43 that drives the movable frame 42 to move. The movable frame 42 is provided with a pushing plate 44 that pushes the heat exchanger fins.

[0055] It should be noted that cylinder 43 can be a rodless cylinder 43, which has advantages such as saving installation space, simple structure, small size and light weight. At the same time, considering the versatility, the width of heat exchanger fins of different specifications are different, so parameter settings are added to the controller, and the stroke of cylinder 43 can be adjusted by solenoid valve to adapt to heat exchanger fins of different specifications.

[0056] The advantage of this design is that the cylinder 43 drives the movable frame 42 to move laterally along the slide rail 41. The movement of the movable frame 42 drives the pusher plate 44 to move, thereby pushing the heat exchanger fins. Therefore, the longitudinal lifting mechanism 3 has a simple structure and is easy to operate. The longitudinal lifting mechanism 3 pushes each layer of heat exchanger fins to the next process.

[0057] In some embodiments of this utility model, the pusher plate 44 is provided with a protective layer made of polyurethane rubber.

[0058] The advantage of this design is that the surface of the pusher plate 44 is provided with a protective layer, which is made of polyurethane elastic rubber. This protective layer is oil-resistant and wear-resistant, which can prevent the oil in the heat exchanger fins from contaminating the protective layer and causing aging. At the same time, the protective layer has high elasticity and will not damage the heat exchanger fins.

[0059] In some embodiments of this utility model, such as Figure 6 As shown, the pusher plate 44 is fixed to the movable frame 42 by the second fastener, and the pusher plate 44 has a square adjustment hole 45 for the second fastener to pass through.

[0060] The advantage of this design is that the pusher plate 44 and the moving frame 42 are fixedly connected by a second fastener (such as bolts), which is convenient to operate. At the same time, the pusher plate 44 is provided with a square adjustment hole 45 so that the fixed position of the pusher plate 44 can be adjusted, and the debugging is also very convenient. This ensures that the pusher plate 44 can abut against the side of the heat exchanger fins during the pushing process, thereby pushing the heat exchanger fins to the next process.

[0061] In some embodiments of this utility model, such as Figure 7 , Figure 8As shown, the feeding platform 2 is equipped with a belt conveyor assembly 21 for moving the multi-layer heat exchanger fins to the destacking and conveying position, and the support frame 1 is equipped with a vision detection module 6 for detecting whether the multi-layer heat exchanger fins have reached the destacking and conveying position.

[0062] It should be noted that the visual inspection module 6 can be a photoelectric sensor, including a transmitter and a receiver respectively mounted on the support frame 1, which can accurately detect the presence or absence of heat exchanger fins.

[0063] The advantage of this design is that the belt conveyor assembly 21 on the loading platform 2 is used to transport the multi-layer heat exchanger fins. After the vision inspection module 6 detects that the multi-layer heat exchanger fins have reached the destacking and conveying position, the lateral feeding of the belt conveyor assembly 21 on the loading platform 2 will stop. This realizes automatic monitoring of the position status of the heat exchanger fins and automatic transmission of the multi-layer heat exchanger fins, which can replace the manual handling of heat exchanger fins, reduce the labor intensity of workers, and improve production efficiency.

[0064] This utility model also provides a heat exchanger production equipment, including the destacking and conveying device with correction function as described above.

[0065] Because the destacking and conveying device with correction function provided by this utility model uses the longitudinal lifting mechanism 3 to lift the feeding platform 2 in stages, so that after each rise, the uppermost heat exchanger fins carried by the feeding platform 2 reach the pushing position, the uppermost heat exchanger fins can be pushed by the transverse pushing mechanism 4. During the process of the transverse pushing mechanism 4 pushing the heat exchanger fins, the correction mechanism 5 is used to correct the shape of the heat exchanger fins, ensuring that each layer of heat exchanger fins is transferred to the next process after correction. This realizes the automatic destacking, correction and transfer of heat exchanger fins, thereby significantly improving the production efficiency of heat exchanger production equipment.

[0066] For ease of understanding, the following description, in conjunction with the accompanying drawings, details the destacking and conveying device with correction function provided in the preferred embodiment of this utility model.

[0067] like Figures 1 to 8 As shown, the destacking and conveying device with correction function provided in this preferred embodiment includes a support frame 1, a feeding platform 2, a longitudinal lifting mechanism 3, a transverse pushing mechanism 4, a correction mechanism 5, a vision inspection module 6, and a controller, etc.

[0068] The support frame 1 is formed by connecting components such as stainless steel plates, aluminum profiles, and bolts. The stainless steel plates are located at the bottom to provide stability and support. The longitudinal lifting mechanism 3 includes lead screws 31 installed at the four corners of the support frame 1 and covered by shielding plates, a transmission sprocket 32 ​​located at the bottom of the stainless steel plate and fixed to the bottom end of the lead screw 31, a drive sprocket 33 connected to the transmission sprocket 32 ​​by a chain, and a motor 34 located at the top of the stainless steel plate and driving the drive sprocket 33 to rotate. A support slider 35 that can move along the lead screw in the longitudinal direction is provided on the lead screw 31, and the support slider 35 is fixedly connected to the loading platform 2. The transverse pushing mechanism 4 includes a pair of slide rails 41 installed in the upper part of the support frame 1, a movable frame 42 movably arranged between the pair of slide rails 41, and a cylinder 43 installed on the upper part of the support frame 1 and driving the movable frame 42 to move. A pusher plate 44 that can move along the slide rails 41 in the transverse direction is provided on the movable frame 42. A belt conveyor assembly 21 is provided on the loading platform 2. The support frame 1 is positioned on both sides along the transverse direction, close to the production line of the previous process (e.g., a conveyor belt) and the production line of the next process (e.g., a conveyor belt). The correction mechanism 5 is a blade with serrated edges, located on the side of the support frame 1 closest to the next process. The vision inspection module 6 includes through-beam photoelectric sensors fixed to the support frame 1 and located near both ends of the blade.

[0069] The specific workflow is as follows: 1) The loading platform 2 is initially located at the bottom of the support frame 1, corresponding to the conveyor belt of the previous process. The worker places the entire stack of heat exchanger fins onto the conveyor belt of the previous process, and the entire stack of heat exchanger fins is conveyed to the loading platform 2 by starting the conveyor belt. 2) The loading platform 2 is initially lifted to the middle position of the support frame 1 by the longitudinal lifting mechanism 3, and the entire stack of heat exchanger fins is also conveyed by the belt conveyor assembly 21 on the loading platform 2. When the vision inspection module 6 detects that the entire stack of heat exchanger fins is in place, the lateral feeding of the belt conveyor assembly 21 on the loading platform 2 is stopped. 3) The conveyor belt for the next process starts, pushing the top layer of heat exchanger fins through the transverse pushing mechanism 4. After being straightened by the blades, the heat exchanger fins reach the next process. After the transverse pushing mechanism 4 retracts, the longitudinal lifting mechanism 3 moves the loading platform 2 up by the thickness of one layer of heat exchanger fins. The transverse pushing mechanism 4 continues to push the top layer of heat exchanger fins, and so on, until all layers of heat exchanger fins are conveyed to the next process. 4) The longitudinal lifting mechanism 3 lowers the loading platform 2 to the initial position, waiting for the next operation.

[0070] In addition, in this preferred embodiment, a material counting module and an empty material alarm module can also be installed. Together with the vision detection module 6, the number, position and size of the heat exchanger fins on the feeding platform 2 can be monitored in real time. By detecting the number of times the heat exchanger fins pass through, the output of the shift can be counted in real time.

[0071] This invention utilizes a combination of a longitudinal lifting mechanism 3 and a transverse pushing mechanism 4 to achieve effective destabilization of stacked materials, significantly improving operational stability. Considering that the materials are composed of multiple layers of heat exchanger fins, which are prone to deformation and tipping during handling, the invention employs a blade with comb-like teeth 51 in conjunction with the transverse pushing mechanism 4. During pushing, the blade passes over the top surface of the heat exchanger fins, automatically correcting any tipping. This invention achieves intelligent material management, eliminating efficiency losses caused by manual intervention and enabling intelligent monitoring of material position. This significantly reduces the need for workers to frequently bend over when placing production materials, greatly reducing labor intensity and harm to the human body, and embodying the core principle of people-centered development in today's society.
