Description

Technical Field

[0001] The present invention belongs to the technical field of fin production equipment, and particularly relates to an automatic stacking and turning blanking device for fins. Background Art

[0002] In modern industrial production, as a core component of equipment such as air conditioners, the production efficiency and quality of fins are directly related to the performance and market competitiveness of the entire product. In the traditional fin production process, operations such as stamping, stacking, and blanking often rely on manual operation, which is not only inefficient but also poses safety hazards. With the continuous development of automation technology, realizing the automation and intelligence of fin production has become an inevitable trend in the industry development.

[0003] After the existing fin automatic stamping equipment completes stamping, it usually collects the fins into a container by a simple dropping method. This method results in the fins being stacked in a disorderly manner, which not only brings inconvenience to the subsequent stacking and blanking operations but also may cause damage to the fins. In addition, the blanking link of the existing equipment usually lacks sufficient flexibility and adaptability, and it is difficult to quickly process a whole stack of fins, resulting in low blanking efficiency of the fins and affecting the production of subsequent processes.

[0004] Therefore, the inventor is committed to designing a device to solve the above problems. Summary of the Invention

[0039] The following combines the drawings to specifically illustrate the implementation mode of the present invention. The drawings are only for reference and explanation, and do not constitute a limitation on the protection scope of the present invention patent.

[0040] Refer to Figures 1 to 19 , an automatic stacking and steering blanking device for fins, including a stamping machine tool 17, a vacuum negative pressure adsorption machine 16 and a base 1. The vacuum negative pressure adsorption machine 16 is arranged at the discharge end of the stamping machine tool 17. On the base 1, an aggregate station, a car-changing station, a steering station and a blanking station are successively arranged from the feeding direction to the discharging direction (from left to right). The vacuum negative pressure adsorption machine 16 is located directly above the aggregate station. A turntable 3 is rotatably connected at the car-changing station. Two material receiving carts 4 are commonly slidably connected at the aggregate station, the turntable 3 and the steering station. An aggregate guide groove 122 is commonly arranged at the aggregate station and the turntable 3. A part of a semi-circular steering guide groove 142 is commonly arranged at the steering station and the turntable 3. The two material receiving carts 4 are in one-to-one corresponding guiding connection with the aggregate guide groove 122 and the steering guide groove 142. A support plate 5 is movably carried on each material receiving cart 4. An aggregate rack 51 is movably supported on the support plate 5. Both the support plate 5 and the aggregate rack 51 are movably sleeved on the aggregate needle 43 of the material receiving cart 4. Two lifting mechanisms 2 for lifting the support plate 5 are arranged at intervals at the aggregate station. An inverting and blanking mechanism 8 is arranged at the blanking station.

[0041] Refer to Figure 1 and Figure 2, the stamping machine 17 is located on the left side of the base 1 and is responsible for the stamping and forming of the fins 31. The vacuum negative pressure adsorption machine 16 is responsible for stably adsorbing the stamped fins 31 and transferring them to the receiving cart 4 at the aggregate station for aggregation. The vacuum negative pressure adsorption machine 16 mainly uses the differential pressure adsorption method to generate an adsorption force by making the pressure in the air chamber lower than the external pressure. The internal and external air pressure difference enables the fins 31 to obtain the adsorption force. When it is necessary to release the fins 31, the pressure in the air chamber can be changed or the rotating door can be opened, etc., so that there is no pressure difference between the inner cavity and the outer cavity, so that the fins 31 fall on the lower aggregate needles 43 or the unloading device under the action of their own gravity.

The two ends of the steering guide groove 142 are both strip-shaped, and the other parts are semicircular (see Figure 4 ).

[0045] Refer to Figure 3 and Figure 4 , two cover plates are respectively provided at the openings of the grooves 15 at the aggregate collection station and at the openings of the grooves 15 at the steering station.

[0050] Reference Figure 13 , Figure 14 and Figure 15 A U-shaped bracket 18 is provided at the edge of the discharge end of the base 1, and both ends of the bracket 18 are fixed on the base 1. The entire bracket 18 and the base 1 together form a lifting and turning space.

[0051] Reference Figure 13 , Figure 14 and Figure 15 The flip member 81 is in a rectangular shape, and the insertion rod 811 and the blocking bar 812 are respectively vertically arranged on two adjacent side walls of the flip member 81, so that the insertion rod 811 and the blocking bar 812 are 90 degrees apart. The two ends of the flip member 81 are respectively connected to the left and right ends of the bracket 18 through sliders 83 for vertical sliding. The flip driving mechanism is arranged on one of the sliders 83. The flip driving mechanism can drive the flip member 81 to rotate a certain angle on the two sliders 83 (the flip member 81 is rotatably arranged between the two sliders 83). The lifting driving mechanism is arranged on the bracket 18, and the two sliders 83 are driven by the lifting driving mechanism to slide vertically.

[0052] Reference Figure 13 , Figure 14 and Figure 15 The flipping drive mechanism includes a flipping motor 82 and a belt transmission mechanism. The flipping motor 82 is arranged on the corresponding slider 83. The driving wheel of the belt transmission mechanism is located at the output end of the flipping motor 82. The driven wheel of the belt transmission mechanism is rotatably arranged between the corresponding slider 83 and the flipping member 81.

The two sliders 83 are correspondingly sleeved on the two screw rods 84. The two rotating shafts 86 are coaxially arranged and located between the two screw rods 84. The top of each screw rod 84 is connected to the corresponding rotating shaft 86 through a commutator 87.

[0054] Reference Figure 14 , Figure 18 and Figure 19 A material unloading trolley 9 is provided on the discharge side of the base 1, and the material unloading trolley 9 includes a bottom frame 91, a plurality of support rods 93, a plurality of bearing rods 92 and a hand push rod 94. The bottom frame 91 is frame-shaped as a whole and a plurality of rollers are provided at the bottom thereof. All the bearing rods 92 are arranged in a row and spaced apart just above the bottom frame 91. The bottom of each bearing rod 92 is connected to the bottom frame 91 through a plurality of support rods 93. The plurality of bearing rods 92 are staggered with a group of baffles 812. The bottom frame 91, the bearing rods 92 and the support rods 93 are all made of metal profiles so that the distance between two adjacent bearing rods 92 can be adjusted. The hand push rod 94 is U-shaped and obliquely arranged on one side of the bottom frame 91.

[0055] Reference Figures 1 to 19 The working principle of the automatic stacking and turning feeding equipment of the fins of the present invention is:

[0056] The punching machine 17 punches out a plurality of fins 31 (each fin 31 is in a long strip shape and has a plurality of through holes spaced thereon), so that each fin 31 is discharged along the length direction of the base 1.

[0057] The vacuum negative pressure adsorption machine 16 stably adsorbs the stamped fins 31 and transfers them to the receiving vehicle 4 (the handle 42 of the receiving vehicle 4 faces forward) at the material collection station for material collection. The lifting parts of the two lifting seats 22 are located directly below the edge of the support plate 5. The left side of the receiving vehicle 4 at the material collection station presses the positioning rod 24. The four positioning cylinders 23 drive their respective pressing blocks 231 to move, and jointly press the empty vehicle seat 41 of the receiving vehicle 4. The two lifting motors control the two lifting screws 21 to rotate synchronously, thereby driving the two lifting seats 22 to rise synchronously, and lifting the support plate 5 and the material collection rack 51 upward together.

[0058] At the aggregate station, as more and more fins 31 are stacked on the aggregate rack 51 (each fin 31 is strip-shaped and falls on the aggregate rack 51 along the length direction of the base 1, and the through holes of each fin 31 pass through the aggregate pins 43), the two lifting seats 22 also gradually descend under the control of two lifting motors until the aggregate rack 51 is full of fins 31;

[0059] The sliding variable-speed motor 6 at the left end of the bottom of the turntable 3 controls the action of the left gear set 61, and then controls the left rack 132 to slide in the groove 15. The guide posts 412 of the left receiving cart 4 slide in the aggregate guide groove 122, driving the receiving cart 4 at the aggregate station to move forward until it reaches the left end of the turntable 3. At the same time, the sliding variable-speed motor 6 at the right end of the bottom of the turntable 3 controls the action of the right gear set 61, and then controls the right rack 132 to slide in the groove 15. The guide posts 412 of the right receiving cart 4 slide in the steering guide groove 142, driving the empty receiving cart 4 at the steering station (the handle 42 of this receiving cart 4 is located on the side) to move backward. When the guide posts 412 of the right receiving cart 4 slide along the semicircular part of the steering guide groove 142, the right receiving cart 4 is turned 90 degrees under the guiding action of the semicircular part of the steering guide groove 142, so that the handle 42 of the right receiving cart 4 is located at the rear until it reaches the right end of the turntable 3 (refer to Figure 6 as shown, the handles 42 of the two receiving carts 4 are close);

[0060] The hydraulic motor 73 controls the rotation of the driving gear 71, which in turn drives the rotation of the driven gear 72, and finally controls the turntable 3 to rotate 180 degrees. To prevent the turntable 3 from further rotating due to inertia, the oil cylinder 7 drives the rotary positioning pin 74 to extend downward into the base 1, so that the turntable 3 accurately stops rotating, and finally the positions of the two receiving carts 4 are swapped;

[0061] On the one hand, the empty receiving cart 4 moves to the aggregate station to receive materials. On the other hand, after the receiving cart 4 full of fins 31 is turned 90 degrees at the steering station (after turning, the individual fins 31 are stacked on the aggregate rack 51 along the width direction of the base 1), an operator passes multiple pins through the other through holes of the whole stack of fins 31;

[0062] When the receiving cart 4 at the steering station continues to slide horizontally on the base 1, the aggregate rack 51 carrying the whole stack of fins 31 (the individual fins 31 are arranged longitudinally along the base 1) also moves horizontally together with the receiving cart 4;

[0063] When the material receiving cart 4 slides to the blanking station, the two insertion rods 811 on the flipping member 81 are respectively inserted into the two insertion holes 52 on the front side of the aggregate rack 51. The lifting motor 85 controls the synchronous rotation of the two rotating shafts 86 through the double-shaft output gearbox 851. The two rotating shafts 86 respectively drive the two lead screws 84 to rotate through their respective commutators 87, thereby controlling the simultaneous upward movement of the two sliders 83, the flipping member 81, and the flipping drive mechanism. The aggregate rack 51 and the entire stack of fins and pins carried thereon rise together with the flipping member 81, causing the aggregate rack 51 and the carried stack of fins to move away from the material receiving cart 4 until the entire stack of fins completely disengages from all the aggregate pins 43 and is blocked by a set of retaining bars 812. The material receiving cart 4 retreats and moves away from the flipping member 81;

[0064] The lifting motor 85 controls the downward movement and reset of the flipping member 81. At the same time, the flipping motor 82 drives the flipping member 81 to slowly flip 90 degrees towards one side of the blanking cart 9 through the belt drive mechanism. The aggregate rack 51 carrying the entire stack of fins also slowly flips 90 degrees together with the flipping member 81, enabling the entire stack of fins to be supported on multiple retaining bars 812. Since the through holes of the entire stack of fins are inserted with pins, the entire stack of fins will not disperse during the process of moving downward and flipping;

[0065] When the entire stack of fins is located on the blanking cart 9, pulling the blanking cart 9 outwards can remove the entire stack of fins with pins inserted, and the flipping member 81 reverses 90 degrees to reset.

[0066] The automatic stacking and turning blanking equipment for fins of the present invention utilizes the lifting mechanism 2 to lift the pallet 5, enabling the stamped fins 31 to be automatically stacked on the material receiving cart 4 at the aggregate station, and then sliding to the turntable 3. By using the rotation of the turntable 3, the two material receiving carts 4 on the turntable 3 are swapped. The swapped material receiving cart 4 turns through the semi-circular part on the steering guide groove 142, and then uses the flipping blanking mechanism 8 to flip and blank, realizing the automated processing of the fins 31 from stacking to blanking, thereby improving production efficiency, reducing production costs, and ensuring product quality and safety at the same time.

[0067] The above-disclosed are only the preferred embodiments of the present invention, and cannot be used to limit the scope of the patent protection of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
