[0025] The utility model provides the following description of reference drawing to help overall understanding various embodiments of the utility model as defined by the claims and its equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.

[0026] In the description of the utility model, the orientation description such as the orientation or positional relationship indicated by up, down, front, back, left, right etc. based on the orientation or positional relationship shown in the drawing is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore can not be understood as the limitation of the utility model.

[0027] It should be understood that when one element (for example, a first element) is "connected" with another element (for example, a second element), the element can be directly connected with the other element, or there can be an intervening element (for example, a third element) between the element and the other element.

[0028] The embodiment of the utility model provides an automatic feeding and discharging device, as Figure 1-5 As shown, it includes: workbench 1, setting in the one side of stamping equipment;

[0029] Bin structure 2, bin structure 2 sets up on workbench 1, including the bin frame 210 for placing workpiece and the bin limiting structure 220 set up on bin frame 210;

[0030] Feeding device 3, setting in the bottom of bin structure 2, feeding device 3 includes the drive structure 310 set up in the one side of bin structure 2, the push groove 320 set up in the bottom of bin structure 2 and the push structure 330 with drive structure 310 is connected and moves in push groove 320, and the push structure 330 top is equipped with the pusher 331 for pushing workpiece;

[0031] Positioning buffer structure 4, setting in the other side of bin structure 2 opposite with push structure 330, positioning buffer structure 4 includes the end positioning structure 410 set up in the end of push groove 320 and the side positioning structure 420 set up in the both sides of push groove 320;

[0032] The taking device 5 is arranged on one side of the workbench 1 and includes a rotatable picking arm 510 and a taking clamp 520 arranged on the picking arm 510, which is used for picking the workpiece on the positioning and buffering structure 4 and picking the workpiece on the stamping equipment.

[0033] The driving structure 310 can be a push rod, a lead screw, a gear or the like, and the pushing part 331 is higher than the pushing groove 320 and can push the workpiece out in the pushing process. The height of the pushing groove 320 determines the number of workpieces pushed out, and the width of the pushing groove 320 changes due to the influence of the pushing position of the workpiece. The stock bin limiting structure 220 further limits the number of workpieces pushed out and improves the stability during pushing. After being constrained by the pushing part 331 and the stock bin limiting structure 220, the number of workpieces pushed out is accurately controlled. The workpiece is pushed to the positioning and buffering structure 4, and the end positioning structure 410 of the positioning and buffering structure 4 buffers and positions the workpiece when the workpiece is pushed to the end of the pushing groove 320, thereby limiting the advancing distance of the workpiece and preventing the workpiece from deviating. The taking clamp 520 on the picking arm 510 can accurately pick the workpiece on the positioning and buffering structure 4 to the stamping equipment for processing. After processing, the taking device 5 picks the workpiece from the stamping equipment to the storage container. The device can also be applied to other equipment that needs to load and unload.

[0034] In some embodiments, as shown in Figure 2 The stock bin limiting structure 220 includes a bottom limiting baffle 230 arranged at the bottom of the stock bin frame 210. The bottom limiting baffle 230 is connected to the side plate of the stock bin frame 210, and a limiting space 231 is formed between the bottom limiting baffle 230 and the pushing groove 320.

[0035] The bottom limiting baffle 230 is connected to the side plate of the stock bin frame 210 opposite to the driving structure 310. The workpiece can be pushed out only through the limiting space 231, which can effectively prevent two workpieces from being pushed together and then being pushed away or displaced, thereby ensuring that one workpiece is pushed out and reducing errors.

[0036] Further, the bottom limiting baffle 230 is fixed to the side plate of the stock bin frame 210 through a height adjusting structure 232. The height adjusting structure 232 is used for adjusting the height between the bottom limiting baffle 230 and the pushing groove 320.

[0037] The height adjusting structure 232 can be a groove formed on both sides of the bottom limiting baffle 230, which can be fixed after being adjusted to an appropriate position by a fastener, thereby facilitating the pushing out of workpieces of different heights.

[0038] In some embodiments, as shown in Figure 1-5As shown, the silo limiting structure 220 includes a side limiting baffle 240 arranged on the silo frame 210, and the side limiting baffle 240 is arranged on the pushing groove 320. The side limiting baffle 240 is provided with a hollow structure 241 above the pushing groove 320, and the pushing part 331 slides in the hollow structure 241.

[0039] like Figure 4 The shape of the workpiece 6 shown is provided with protruding structures on both sides of the pushing direction of the pushing part 331. The side limit baffle 240 on one side of the pushing part 331 limits the workpiece 6 in the hopper and blocks the protruding structures on both sides. The hollow structure 241 arranged on the pushing groove 320 allows the pushing part 331 to slide to the required pushing structure 330 without affecting the limit, thereby reducing accidental touch and guiding the pushing part 331 to improve stability during pushing.

[0040] In some embodiments, a position adjustment structure 250 is provided on one side of the silo frame 210 , and the position adjustment structure 250 is used to adjust the size of the space for placing the workpiece in the silo frame.

[0041] The setting of the position adjustment structure 250 provides great flexibility, adapts to multiple types of workpieces, and increases the practicality of the equipment.

[0042] In some embodiments, as Figure 1-4 As shown, the end positioning structure 410 includes a first limiting top block 411 provided at the end of the pushing groove 320 , and the height of the first limiting top block 411 is higher than the pushing groove 320 .

[0043] When the pushing structure 330 pushes the workpiece to a designated position in the pushing groove 320 , the first limiting top block 411 at the end of the pushing groove 320 can control the workpiece to continue moving forward without inertia.

[0044] Further, if Figure 3-4 As shown, the end positioning structure 410 includes a sensor 412 , and the sensor 412 is arranged on one side of the first limiting top block 411 .

[0045] The sensor 412 can sense that the workpiece is pushed into the positioning buffer structure 4, making it easier for the picking arm 510 to pick up the workpiece.

[0046] Further, if Figure 3-4 As shown, the end positioning structure 410 includes an elastic blocking structure 413 , and the elastic blocking structure 413 is arranged on one side of the first limiting top block 411 .

[0047] The elastic blocking structure 413 can effectively offset inertia while protecting the workpiece from being damaged.

[0048] In some embodiments, as Figure 2-4As shown, the side positioning structure 420 includes a second limiting top block 421 provided on one side of the pushing groove 320 .

[0049] The second limiting top block 421 is provided to facilitate limiting the structures on both sides of the workpiece, so that the workpiece will not deviate. When the workpiece arrives, it is limited by the positioning structures on both sides.

[0050] In some embodiments, as Figure 1 As shown, the material taking fixture 520 is provided with more than two fixtures.

[0051] For example, if one side is a pneumatic clamp and the other side is a magnetic clamp, the combination of the two can handle more types of workpieces.

[0052] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
