Technical Field

[0002] Heat dissipation fins are one of the main components of a heat exchanger. They are made from aluminum or copper strips, cut and punched into long, thin strips.

In existing technology, manufacturers use thin rods inserted into through-holes at both ends of the heat dissipation fins to limit their movement and facilitate storage. However, manually collecting the heat dissipation fins is inefficient, easily causes bending, and the sharp edges of the fins can cause cuts and other safety hazards. Utility Model Content

[0028] Reference Figures 1 to 5 The adsorption-type discharge device for the heat exchanger fins of this utility model is illustrated in the following embodiment:

[0029] An adsorption-type discharge device for heat exchanger fins includes: a negative pressure generating element 100, an exhaust duct 200, and an adsorption plate 300.

[0030] The negative pressure generating element 100 and the adsorption plate 300 are arranged vertically, with the adsorption plate 300 located below the negative pressure generating element 100. One end of the exhaust pipe 200 is connected to the negative pressure generating element 100, and the other end is connected to the upper end of the adsorption plate 300. The lower end of the adsorption plate 300 is provided with an adsorption surface 310, and the adsorption surface 310 is provided with a plurality of adsorption holes 311 arranged thereon. The adsorption holes 311 penetrate the adsorption surface 310 and are connected to the negative pressure generating element 100 through the exhaust pipe 200.

[0031] In practical use, the negative pressure generated by the negative pressure generating element 100 can be transmitted to the adsorption plate 300 through the exhaust pipe 200. The heat dissipation fins are continuously adsorbed onto the lower side of the adsorption surface 310 through the adsorption holes 311 of the adsorption plate 300, thereby realizing the adsorption and discharge of the heat dissipation fins. The negative pressure generating element 100 is located above the adsorption plate 300 and will not obstruct the adsorption surface 310.

[0032] In this embodiment, the adsorption-type discharge device is located at the front of the stamping equipment, and the rear end of the adsorption surface 310 is set according to the discharge height of the heat dissipation fins. In this embodiment, the upper end of the exhaust duct 200 is connected to the stamping equipment via a fixed bracket, so that the rear end of the adsorption plate 300 is fixed to the upper side of the discharge port of the stamping equipment. When the heat dissipation fins are discharged forward, they can be adsorbed onto the lower side of the adsorption surface 310 through the adsorption holes 311. In this embodiment, the negative pressure generating element 100 is an exhaust fan; when its impeller rotates, it generates low pressure, thereby allowing the heat dissipation fins to be adsorbed onto the adsorption surface 310 under negative pressure during the discharge process.

[0033] The adsorption disk 300 has a box-like shape, wider at the bottom and narrower at the top. The adsorption surface 310 is rectangular, and the adsorption holes 311 are arranged in multiple rows on the adsorption surface 310. In this embodiment, the adsorption disk 300 is trapezoidal in its left-right projection. Both the top and bottom ends of the adsorption disk 300 are rectangular planes. The exhaust pipe 200 is connected to the upper middle part of the adsorption disk 300. The front and rear ends of the adsorption disk 300 are suspended and have a small thickness, thereby enhancing the stress-bearing structure at the front and rear ends.

[0034] In this embodiment, both the exhaust duct 200 and the adsorption plate 300 are sheet metal products, and the lower end of the exhaust duct 200 is fixedly connected to the adsorption plate 300. Specifically, the lower end of the exhaust duct 200 has an outwardly folded edge, which fits against the upper end of the adsorption plate 300, and is locked and fixed to the adsorption plate 300 by screws and nuts passing through it. In other embodiments, the folded edge and the adsorption plate 300 can be fixed to each other by welding.

[0035] In this embodiment, the exhaust duct 200 is rectangular in shape. Both the front and rear sides of the exhaust duct 200 are provided with pressure relief holes 210, and each pressure relief hole 210 is equipped with an openable and closable pressure relief baffle 220. When the heat dissipation fins reach the required length, they are cut and completely discharged forward onto the adsorption surface 310. At this point, the vacuum within the adsorption plate 300 needs to be released, allowing the heat dissipation fins to fall onto a storage rack or transport vehicle to complete the discharge. When the pressure relief baffle 220 is opened, the pressure relief hole 210 is open, eliminating the negative pressure and allowing the heat dissipation fins to fall. When the pressure relief baffle 220 is closed, it covers the pressure relief hole 210, and the negative pressure generated by the negative pressure generating element 100 can be transmitted to the adsorption hole to adsorb the heat dissipation fins, allowing them to be discharged forward along the adsorption surface 310.

[0036] The exhaust duct 200 is provided with a pressure loss driving mechanism 230. In this embodiment, the pressure loss baffle 220 is rotatably disposed on the pressure loss hole 210, and the pressure loss driving mechanism 230 is used to drive the pressure loss baffle 220 to rotate relative to the exhaust duct 200.

[0037] The pressure relief hole 210 is provided with a left-right extending rotating shaft 221, which is rotatably connected to the exhaust duct 200. The pressure relief baffle 220 is fixedly connected to the rotating shaft 221, thereby allowing the pressure relief baffle 220 to rotate relative to the exhaust duct 200, thus opening and closing the pressure relief hole 210. The middle part of the rotating shaft 221 is fixedly connected to the pressure relief baffle 220, and both the left and right ends of the rotating shaft 221 are rotatably connected to the exhaust duct 200.

[0038] The pressure relief baffle 220 is in the shape of a thin plate, and the rotating shaft 221 is fixedly disposed in the middle of the pressure relief baffle 220 so that the pressure relief baffle 220 is divided into an outer baffle 222 and an inner baffle 223.

[0039] The width of the pressure relief hole 210 is smaller than the width of the exhaust duct 200. In actual use, the outer baffle 222 and the inner baffle 223 are respectively located on the front and rear sides of the pressure relief hole 210. The width of both the outer baffle 222 and the inner baffle 223 is greater than the width of the pressure relief hole 210. A clearance groove is provided between the outer baffle 222 and the inner baffle 223, and the clearance groove is located at the left and right ends of the pressure relief baffle 220. The middle of both ends of the pressure relief hole 210 is engaged between the outer baffle 222 and the inner baffle 223.

[0040] The widths of both the outer baffle 222 and the inner baffle 223 are greater than the width of the pressure relief hole 210. The clearance grooves allow the inner baffle 223 to be positioned on the side of the pressure relief hole 210 facing inwards towards the exhaust duct 200, while the outer baffle 222 is positioned on the side of the pressure relief hole 210 facing outwards towards the exhaust duct 200. When the pressure relief drive mechanism 230 rotates the pressure relief baffle 220, the outer baffle 222 is positioned on the outside of the exhaust duct 200, and the inner baffle 223 is positioned on the inside of the exhaust duct 200.

[0041] The exhaust duct 200 is provided with pressure relief holes 210 and pressure relief baffles 220 on both the front and rear sides. By having the pressure relief holes 210 and pressure relief baffles 220 arranged in pairs move synchronously, when the pressure relief holes 210 are opened, the exhaust duct 200 can be connected to the outside area over a larger area, thereby completely breaking the vacuum on the adsorption surface 310, allowing the heat dissipation fins to fall off smoothly to collect the material.

[0042] The pressure relief drive mechanism 230 is synchronously connected to the rotating shafts 221 of the two pressure relief baffles 220. Specifically, the pressure relief drive mechanism 230 includes a pressure relief drive unit, a drive disk 231, and a transmission rod 232. The drive disk 231 is rotatably disposed on one side of the exhaust duct 200, and the pressure relief drive unit is used to drive the drive disk 231 to rotate relative to the exhaust duct 200. The two ends of the transmission rod 232 are eccentrically connected to the drive disk 231 and the rotating shaft 221, respectively. The rotating shaft 221 of the drive disk 231 is located at the midpoint of the line connecting the rotating shafts 221 of the two pressure relief baffles 220. There are two transmission rods 232, which are respectively disposed on the front and rear sides of the drive disk 231 and are respectively connected to the rotating shafts 221 of the two pressure relief baffles 220.

[0043] The pressure loss driving component can be a rotary cylinder, servo motor, stepper motor, or pneumatic motor, or other rotary drive element. The drive disk 231 and the transmission rod 232 form a crank-rocker mechanism, thereby driving the pressure loss baffle 220 to rotate around the corresponding rotation axis 221. The front and rear pressure loss baffles 220 and the transmission rod 232 are centrally symmetrical about the rotation axis 221 of the drive disk 231.

[0044] In this embodiment, the pressure loss drive mechanism 230 is located on the left side of the exhaust duct 200, and the right side of the exhaust duct 200 is also provided with a linkage rod 240. The two ends of the linkage rod 240 are respectively eccentrically connected to the rotating shaft 221 of the front and rear pressure loss baffles 220, so that the left and right ends of the rotating shaft 221 can be evenly stressed.

[0045] In other embodiments, the pressure loss drive mechanism 230 can drive the two pressure loss baffles 220 of the pressure loss holes 210 on the front and rear sides to rotate through two pressure loss drive components respectively. It is understood that in these embodiments, the rotation shafts 221 of the two pressure loss baffles 220 can also be synchronously connected through the aforementioned linkage rod 240.

[0046] Furthermore, to ensure that the pressure relief baffle 220, in its closed state, can press against the exhaust duct 200 and thus cover and seal the pressure relief hole 210, the outer baffle 222 and the inner baffle 223 are staggered. On the left-right projection plane, the middle section of the pressure relief baffle 220 is stepped, with a height difference between the outer baffle 222 and the inner baffle 223. The magnitude of this height difference is determined by the wall thickness of the exhaust duct 200 at the pressure relief hole 210, so that when the pressure relief baffle 220 is rotated to its extreme position, both the outer baffle 222 and the inner baffle 223 can simultaneously press against the exhaust duct 200.

[0047] In some other embodiments, the pressure relief baffle 220 is slidably disposed on the pressure relief hole 210, and the pressure relief driving mechanism 230 can drive the pressure relief baffle 220 to slide relative to the pressure relief hole 210, thereby realizing the opening and closing switching of the pressure relief hole 210.

[0048] In a further embodiment, the adsorption surface 310 has multiple clearance holes arranged in a left-right direction at both its front and rear ends. When the material for the heat dissipation fins is conveyed forward along the adsorption surface 310, the receiving mechanism below the adsorption-type discharge device moves upward, and the receiving guide rods are inserted into the holes at both ends of the heat dissipation fins to receive the material. The clearance holes can accommodate the ends of the receiving guide rods, facilitating material reception.
