Description

Technical Field

[0001] This utility model belongs to the field of air conditioner fin manufacturing technology, and specifically relates to an air conditioner fin stamping part collection device. Background Technology

[0002] An air conditioner fin stamping part collection device is an auxiliary device used to automatically, orderly, and neatly stack and collect air conditioner fins after high-speed stamping. It aims to improve the degree of production automation, prevent fins from being scattered, deformed, or scratched, and facilitate subsequent handling, packaging, or inspection operations. This device is usually located at the end of the stamping production line and realizes centralized management of finished fins through processes such as conveying, positioning, unloading, and stacking.

[0003] Existing air conditioner fin stamping collection devices use a conveyor belt to transport the stamped air conditioner fins to a negative pressure adsorption fan, where the fan holds them until the flanged holes of the fins align with the receiving column. The fan is then turned off, allowing the fins to slide through the internal flanged holes onto the receiving column and fall onto the receiving plate. This process is repeated to achieve neat collection of the fins. However, when the fins slide through the flanged holes into the receiving column, the distance to the receiving plate is too great, causing the high-speed falling fins to collide hard with the fixed receiving plate or the fins already on it. Thin-walled flanged holes, bridge plates, or corrugated structures are particularly prone to bending and collapse, affecting product quality. Furthermore, frequent impacts generate significant noise, impacting the working environment. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an air conditioner fin stamping part collection device. It adopts a liftable receiving buffer plate to ensure that the fin drop distance is short and stable, achieving a "gentle landing" that significantly reduces impact force and prevents the flange holes from collapsing. Furthermore, the liftable receiving buffer plate can push the neat air conditioner fins out of the receiving column, facilitating unloading by personnel.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an air conditioner fin stamping part collecting device, including a base frame, a rotating frame plate is provided at the upper end of the base frame, a fixed cavity plate is rotatably provided inside the rotating frame plate through a rotating column, a cavity plate is provided on the outer side of the fixed cavity plate, multiple sliding plates are slidably provided inside the cavity plate, multiple receiving columns are provided at the upper end of each sliding plate, a receiving buffer plate is slidably provided between the outer arc surfaces of the multiple receiving columns, an adjusting mechanism for adjusting the height of the receiving buffer plate is provided inside the fixed cavity plate, a rotating mechanism is provided on the front side of the rotating frame plate, the adjusting mechanism includes a lifting cavity frame slidably provided inside the fixed cavity frame, the upper side of the lifting cavity frame is connected to the lower side of the receiving buffer plate, a lead screw is rotatably provided inside the fixed cavity frame, the lower end of the lifting cavity frame is threadedly connected to the lead screw, a drive unit one for driving the lead screw to rotate is provided at the lower end of the fixed cavity frame, the drive unit one includes a motor one provided at the lower end of the fixed cavity frame, the output shaft of the motor one is connected to the lower end of the lead screw through a coupling.

[0006] As a further improvement of this utility model, the cavity plate is provided with multiple sliding columns inside, and two sliding plates are slidably connected to the outer arc surface of adjacent sliding columns respectively. A bidirectional lead screw is rotatably provided inside the cavity plate, and two sliding plates are threadedly connected to the front and rear corresponding ends of the bidirectional lead screw respectively. A handwheel is provided at the front end of the bidirectional lead screw.

[0007] As a further improvement of this utility model, the rotating mechanism includes a mounting shell disposed on the front side of the rotating frame plate, a worm gear rotatably disposed inside the mounting shell, a worm wheel disposed at the front end of the rotating column, the worm wheel being meshed with the worm gear, and a second drive unit for driving the worm gear to rotate disposed inside the mounting shell, the second drive unit including a second motor disposed inside the mounting shell, the output shaft of the second motor being connected to the rear end of the worm gear through a coupling.

[0008] As a further improvement of this utility model, the base frame has multiple mounting holes inside, which are located at the four corners of the base frame.

[0009] As a further improvement of this utility model, a buffer pad is provided at the upper end of the receiving buffer plate, and the receiving buffer plate and the buffer pad are bonded together.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by controlling the motor to rotate forward, the lead screw is driven to rotate, which in turn drives the receiving buffer plate on the lifting cavity plate to a high position. This allows the air conditioning fins released by the negative pressure fan to accurately slide into the receiving column through its flanged holes and gently fall onto the receiving buffer plate. Then, the motor is controlled to rotate in reverse, causing the receiving buffer plate and the collected fins to move downward by 2-5cm, making room for the next fin. This process is repeated to ensure that each subsequent fin falls gently from a very short distance (only slightly higher than the previous one) onto the surface of the stacked fins. The use of a liftable receiving buffer plate ensures that the fin falling distance is short and stable, achieving a "gentle landing," significantly reducing the impact force and preventing the flanged holes from collapsing.

[0011] Secondly, a buffer pad is installed at the upper end of the receiving buffer plate, which can effectively absorb the impact energy when the air conditioner fins fall, reduce the hard collision between the fins and the receiving surface, and prevent thin-walled structures such as flange holes and bridge plates from bending, deforming or collapsing.

[0012] Thirdly, by controlling the operation of motor two, the output shaft drives the worm gear to rotate, which in turn drives the meshing worm wheel to rotate, causing the fixed cavity plate on the rotating column to rotate, and causing the air conditioner fin stack on the receiving buffer plate to rotate 90 degrees to the right. Then, the personnel align the column of the external storage mechanism with the position of the flange hole of the air conditioner fin stack, and then control the operation of motor one to move the receiving buffer plate to the right, pushing the air conditioner fin stack on the receiving column onto the column inside the storage mechanism. The rising and falling receiving buffer plate pushes the neatly arranged air conditioner fins out of the receiving column, making it easy for personnel to unload.

[0013] Fourth, by rotating the handwheel to drive the bidirectional lead screw, the receiving columns on both sides of the sliding plate can be driven to move back and forth in coordination with the guide of the limiting column and the groove of the receiving buffer plate. This allows for flexible adjustment of the distance between the two receiving columns, which can adapt to the differences in the spacing of the flange holes of different models of air conditioner fins. This effectively solves the problem that traditional fixed receiving columns cannot be compatible with multiple specifications of products. It not only improves the versatility and changeover efficiency of the collection device, but also ensures that the fins can be accurately fitted into the receiving columns when they are dropped, preventing misalignment, jamming or deformation, and ensuring neat, stable and reliable stacking.

Detailed Implementation

[0017] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0018] like Figure 1 , 2 As shown in Figures 3 and 4, an air conditioner fin stamping part collection device includes a base frame 101. Multiple mounting holes 102 are provided inside the base frame 101. The base frame 101 is fixed to the lower end of a negative pressure fan via bolts through the mounting holes 102, ensuring that the air conditioner fins do not shift during collection. A rotating frame plate 103 is provided at the upper end of the base frame 101. A fixed cavity plate 203 is rotatably mounted inside the rotating frame plate 103 via a rotating column. A cavity plate 203 is provided on the outer surface of the fixed cavity plate 203. Multiple sliding plates 204 are slidably mounted inside the cavity plate 203. Multiple receiving columns 205 are provided at the upper end of each sliding plate 204. A receiving buffer plate 206 is slidably mounted between the outer arc surfaces of the multiple receiving columns 205. A buffer pad 207 is provided at the upper end of the receiving buffer plate 206. An adjustment mechanism for adjusting the height of the receiving buffer plate 206 is provided inside the fixed cavity plate 203. A rotating mechanism is provided on the front side of the rotating frame plate 103.

[0019] like Figure 2 , 3 As shown, the adjustment mechanism includes a lifting cavity frame 209 slidably disposed inside the fixed cavity frame 208. The upper side of the lifting cavity frame 209 is connected to the lower side of the receiving buffer plate 206. A lead screw 202 is rotatably disposed inside the fixed cavity frame 208. The lower end of the lifting cavity frame 209 is threadedly connected to the lead screw 202. A drive unit 1 for driving the lead screw 202 to rotate is disposed at the lower end of the fixed cavity frame 208. The drive unit 1 includes a motor 201 disposed at the lower end of the fixed cavity frame 208. The output shaft of the motor 201 is connected to the lower end of the lead screw 202 through a coupling.

[0020] First, the collection device is placed below the negative pressure fan. By controlling the forward rotation of motor 201, the lead screw 202 is rotated, driving the receiving buffer plate 206 on the lifting cavity plate 203 to a high position. This allows the air conditioning fins released by the negative pressure fan to accurately slide into the receiving column 205 through its flange holes and gently fall onto the receiving buffer plate 206. Then, the motor 201 is controlled to reverse, causing the receiving buffer plate 206, along with the collected fins, to move downwards by 2-5 cm, making room for the next fin. This process is repeated to ensure that each subsequent fin falls slowly from a very short distance (only slightly higher than the previous one) onto the surface of the stacked fins. This effectively avoids flange deformation, bridge collapse, or stacking misalignment caused by free fall, achieving high-precision, damage-free, neat, and orderly continuous automatic collection.

[0021] The lead screw 202 can be a trapezoidal lead screw or a ball screw, which can bear the weight of dozens to hundreds of fins in a stack (usually each fin weighs only tens of grams, and the weight of the whole stack is in the range of several kilograms). Due to the high axial stiffness and load-bearing capacity of the lead screw 202 structure, especially when combined with the guide mechanism, it can maintain good stability and accuracy even in frequent start-stop and reciprocating motion, ensuring that the fin stack does not tilt or shake during the lifting process.

[0022] like Figure 2 , 3 As shown, the rotating mechanism includes a mounting shell 301 disposed on the front side of the rotating frame plate 103. A worm gear 302 is rotatably disposed inside the mounting shell 301. A worm wheel 303 is disposed at the front end of the rotating column. The worm wheel 303 is meshed with the worm gear 302. A second drive unit for driving the worm gear 302 to rotate is disposed inside the mounting shell 301. The second drive unit includes a second motor 304 disposed inside the mounting shell 301. The output shaft of the second motor 304 is connected to the rear end of the worm gear 302 through a coupling.

[0023] When it is necessary to unload the fully collected stack of air conditioner fins from the receiving column 205, the second motor 304 is first started. Its output shaft drives the worm gear 302 to rotate, which in turn drives the meshing worm wheel 303 to rotate. Since the worm wheel 303 is fixed on the rotating column, it drives the fixed cavity plate 203 and the receiving buffer plate 206 connected to it to rotate smoothly by 90 degrees. This causes the fin stack, which was originally vertically mounted on the receiving column 205, to turn to the horizontal direction, ensuring that its flanged holes face the external storage mechanism. Then, the operator precisely aligns the receiving column of the storage mechanism with the flanged hole position of the fin stack. Next, the first motor 201 is controlled to run, driving the lead screw 202 to rotate, which drives the receiving buffer plate 206 to move horizontally to the right, pushing the entire stack of fins to slide out along the receiving column 205 and smoothly mount onto the column of the storage mechanism, completing the automatic unloading and transfer.

[0024] According to another embodiment of the present invention, such as Figure 4 As shown, the cavity plate 203 has multiple sliding columns 401 inside, and two sliding plates 204 are slidably connected to the outer arc surface of the adjacent sliding column 401. A bidirectional lead screw 402 is rotatably installed inside the cavity plate 203. The two sliding plates 204 are threadedly connected to the front and rear corresponding ends of the bidirectional lead screw 402. A handwheel 403 is provided at the front end of the bidirectional lead screw 402. The bidirectional lead screw 402 and the handwheel 403 are fixed together by welding.

[0025] Rotating the handwheel 403 can drive the bidirectional lead screw 402 to rotate, which in turn drives the receiving columns 205 on both sides of the sliding plate 204 to move back and forth under the restriction of the limiting column and the slot opened in the receiving buffer plate 206, thereby changing the spacing of the receiving columns 205 on both sides to adapt to the receiving and collection operation of different specifications of air conditioner fin flange hole spacing.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
