[0033] The present invention provides a sheet metal frame part stamping and forming equipment. The technical solution of the present invention will be described in detail below with reference to the drawings to make it easier to understand and master.

[0034] The sheet metal frame part stamping and forming equipment, as Figures 1 to 3 shown, includes a stamping mechanism 1, a workpiece conveying mechanism 2, a workpiece rotating mechanism 3, a workpiece flatness detecting mechanism 4, a sorting mechanism 5, a packaging mechanism 6, and an operating mechanism 7.

[0035] Specifically, the stamping mechanism 1 is used to stamp a strip into a sheet metal frame part. The workpiece conveying mechanism 2 is used to receive the sheet metal frame part and convey it to the loading area 20. The workpiece rotating mechanism 3 is used to adjust the rotational position of the sheet metal frame part. The workpiece flatness detection mechanism 4 is used to detect the flatness of the sheet metal frame part. The sorting mechanism 5 is used to collect defective products or carry qualified products. The packaging mechanism 6 is used to receive qualified products, align them, and then output them for packaging. The operating mechanism 7 is used to transfer the sheet metal frame part in the loading area 20 to the workpiece rotating mechanism, transfer the sheet metal frame part on the workpiece rotating mechanism to the workpiece flatness detection mechanism, transfer the sheet metal frame part on the workpiece flatness detection mechanism to the sorting mechanism, and transfer the qualified products on the sorting mechanism to the packaging mechanism.

[0036] Specific implementation process and principle description:

[0037] The strip enters the stamping mechanism 1 for stamping to form a sheet metal frame part. It should be noted that, in order to avoid material waste and improve efficiency, a design is adopted in which the long side of the sheet metal frame part is perpendicular to the running direction of the strip.

[0038] The formed sheet metal frame part falls onto the workpiece conveying mechanism 2. The workpiece conveying mechanism 2 transfers the sheet metal frame part to the loading area 20. At this time, the operating mechanism 7 picks up the sheet metal frame part in the loading area 20 and places it on the workpiece rotating mechanism 3. After the workpiece rotating mechanism 3 rotates the sheet metal frame part by 90°, the operating mechanism 7 then picks it up and transfers it to the workpiece flatness detection mechanism 4 for flatness detection. After the detection, the operating mechanism 7 picks it up and places it into the sorting mechanism 5. The sorting mechanism 5 performs sorting operations according to the flatness detection results. When it is a defective product, the defective product is discharged. When it is a qualified product, it carries the qualified product. Finally, the operating mechanism 7 picks up the qualified product and transports it to the packaging mechanism 6, where alignment and output packaging operations are performed on the packaging mechanism 6.

[0039] It should be noted that the operating mechanism 7 can be implemented by several independent operating units or operate in a linkage manner. The independent implementation will not be elaborated here.

[0040] In a specific embodiment, the operating mechanism 7 includes a horizontal bracket 70 and a horizontal bracket drive source. The horizontal bracket 70 has two pick-and-place displacements spaced horizontally. Under the action of the horizontal bracket drive source, the horizontal bracket 70 switches its span between the two pick-and-place displacements. The so-called span switching means an arched displacement between two points.

[0041] The horizontal bracket 70 is provided with a first negative pressure adsorption end 71, a second negative pressure adsorption end 72, a third negative pressure adsorption end 73, and a fourth negative pressure adsorption end 74 that are distributed at intervals.

[0042] The first negative pressure adsorption end is used for displacement switching between the loading area and the workpiece rotating mechanism, the second negative pressure adsorption end is used for displacement switching between the workpiece rotating mechanism and the workpiece flatness detection mechanism, the third negative pressure adsorption end is used for displacement switching between the workpiece flatness detection mechanism and the sorting mechanism, and the fourth negative pressure adsorption end is used for displacement switching between the sorting mechanism and the packaging mechanism.

[0043] Referring to Figure 1 , during the picking operation, the first negative pressure adsorption end 71 is located in the loading area, the second negative pressure adsorption end 72 is located on the workpiece rotating mechanism, the third negative pressure adsorption end 73 is located on the workpiece flatness detection mechanism, and the fourth negative pressure adsorption end 74 is located on the sorting mechanism. At this time, it is in the negative pressure picking state.

[0044] Referring to Figure 2 , during the releasing operation, the first negative pressure adsorption end 71 is located on the workpiece rotating mechanism, the second negative pressure adsorption end 72 is located on the workpiece flatness detection mechanism, the third negative pressure adsorption end 73 is located on the sorting mechanism, and the fourth negative pressure adsorption end 74 is located on the packaging mechanism. At this time, it is in the pressure releasing and discharging state.

[0045] During the operation, the rotating mechanism 7 performs repetitive actions such as Figure 1 and Figure 2 to meet the switching position operations between each working station.

[0046] In a specific embodiment, the horizontal support driving source includes a pivot rocker arm 75 and a pivot seat 76 provided on the horizontal support 70. One end of the pivot rocker arm is provided with a pivot driving source, and the other end is rotatably connected to the pivot seat.

[0047] Specifically, the pivot seat is arranged at the center of gravity position of the horizontal support. When the pivot rocker arm 75 rotates and displaces, it realizes the arch-shaped switching displacement drive. The pivot seat 76 rotates with one end of the pivot rocker arm 75, and the horizontal support maintains a horizontal state.

[0048] In a specific embodiment, the rotating mechanism 7 includes two vertically spaced slide rails 77, and two horizontal slide seats 78 are provided on the horizontal support. The horizontal slide seats are slidably connected to the vertical slide rails in a one-to-one correspondence.

[0049] Specifically, through the cooperation of the two vertically arranged slide rails 77 and the two horizontal slide seats 78, the levelness of the horizontal support is more reliable and stable, and the picking alignment is more accurate.

[0050] In a specific embodiment, the workpiece conveying mechanism 2 includes a conveying circulating belt 21 and an inclined guide rail 22 for guiding the discharged material of the stamping mechanism 1 onto the conveying circulating belt 21. A guide groove 23 for guiding the sheet metal frame parts is provided on the conveying circulating belt 21. The loading area 20 is arranged at the end of the guide groove, and an auxiliary limiting rod 24 is provided on the guide groove 23.

[0051] Specifically, the inclined guide rail 22 can provide a certain height difference for conveying. The guiding groove 23 is used for guiding the workpiece in a matching manner, and the auxiliary limiting rod 24 is used to press the workpiece against the conveying circulating belt 21 to prevent the workpiece from jumping up, so that the position accuracy of the workpiece in the loading area 20 is precise and reliable.

[0052] In a specific embodiment, the workpiece rotating mechanism 3 includes a rotating carrier 31. A transparent support plate is provided at the bottom of the bearing area of the rotating carrier 31, and a visual inspection part is provided at the bottom of the transparent support plate.

[0053] Specifically, the inspection items of the sheet metal frame parts are different. Generally, only the flatness inspection is required. However, some sheet metal frame parts have hollow grooves, and the shape of the hollow grooves needs to be detected. For this situation, the design of the bottom visual inspection part is adopted, that is, a light-transmissive transparent support plate is provided at the bottom of the rotating carrier 31. The visual inspection part includes a light source and an imaging element, and can collect images of the workpieces on the rotating carrier 31 to perform hollow shape detection.

[0054] That is, the functions of rotation adjustment displacement and visual inspection are integrated. The combination is very ingenious.

[0055] In a specific embodiment, the sorting mechanism 5 includes a sorting carrier 51 with horizontal linear displacement and a defective product collection box 52 for receiving defective products. A good product carrier 511 and a defective product guiding groove 512 are provided on the sorting carrier 52.

[0056] Specific implementation process and principle description:

[0057] When the flatness inspection mechanism 4 detects that the product is unqualified, the sorting carrier 51 displaces until the defective product guiding groove 512 is located at the bottom of the negative pressure adsorption end. At this time, the defective products released by the negative pressure adsorption end are guided into the defective product collection box 52 by the defective product guiding groove 512. When the operating mechanism 7 switches the picking displacement, the negative pressure adsorption end corresponding to the defective product guiding groove 512 is empty.

[0058] When the flatness inspection mechanism 4 detects that the product is qualified, the sorting carrier 51 displaces until the good product carrier 511 is located at the bottom of the negative pressure adsorption end, and at this time, it serves as an intermediate transition bearing.

[0059] It should be noted that when the workpiece rotating mechanism 3 has a detection function, the flatness inspection mechanism 4 still meets the matching displacement requirements. That is, in the control architecture, the workpiece rotating mechanism 3 triggers the good product as a, and the flatness inspection mechanism triggers the good product as b. When sorting by the sorting mechanism 5, the good product carrier 511 is triggered to align only when the states of communication a and b are received in sequence, and in other cases, the defective product guiding groove 512 is triggered to align. This double-detection position trigger belongs to the prior art and will not be elaborated here.

[0060] In a specific embodiment, the packaging mechanism 6 includes an aligning circulating belt 61 for receiving and aligning sheet metal frame parts, a loading mechanism 62 for placing loading trays, and a loading mechanism 63 for transferring the sheet metal frame parts on the aligning circulating belt to the loading trays.

[0061] That is, the qualified sheet metal frame parts are equally spaced and aligned on the aligning circulating belt 61, and a number of sheet metal frame parts are synchronously picked up and loaded onto the loading trays by the loading mechanism 63.

[0062] In a specific embodiment, the aligning circulating belt 61 is provided with a stepping drive source 611. A material discharging area 612 for receiving the discharged materials of the operating mechanism 7 is provided on the aligning circulating belt 611, and a radio frequency sensor 613 communicatively connected to the stepping drive source 611 is provided in the material discharging area 612.

[0063] That is, after the operating mechanism 7 discharges materials, the sheet metal frame parts will trigger the radio frequency sensor 613 in the material discharging area 612, and the radio frequency sensor 613 gives a stepping signal to the stepping drive source 611, thereby enabling the requirement of equal-spacing alignment.

[0064] Through the above description, it can be found that the stamping and forming equipment for sheet metal frame parts of the present invention can realize the automated production of sheet metal frame parts, meet the requirements of the assembly line operations of forming, adjusting positions, detecting and screening, and aligning and boxing, improve work efficiency, reduce labor costs, and have high economic value. The operating mechanism is ingeniously designed, has the function of combined operation at multiple stations, operates efficiently and stably, and meets the requirements of flexible material transfer in the automated production line. The overall structure is simple and compact, occupies less space, and is suitable for popularization and application.

[0065] The technical solution of the present invention has been fully described above. It should be noted that the specific embodiments of the present invention are not limited by the above description. All technical solutions formed by those of ordinary skill in the art through equivalent transformation or equivalent substitution in terms of structure, method or function according to the spirit of the present invention fall within the protection scope of the present invention.
