Description

Technical Field

[0001] This utility model belongs to the field of automatic feeding technology, and in particular relates to an automatic feeding device for stamping. Background Technology

[0002] like Figure 3 The image shows a small hardware component 1, which includes a hardware body 11 and side plates 12 disposed on both sides of the hardware body 11. The side plates 12 are curved upwards. (The last sentence appears to be incomplete and possibly refers to a technical detail.) Figure 3 When the small hardware part 1 shown is stamped and shaped, it is generally necessary to manually place it into the stamping and shaping die, and then stamp and shape it through the pressing mechanism of the stamping and shaping equipment. However, manual loading has technical problems such as low loading efficiency and high labor intensity. In particular, the small hardware part 1 is small in size and the two side plates 12 are curved, making it difficult for workers to quickly pick it up and transfer it into the stamping and shaping die, further reducing the loading efficiency.

[0003] Existing technologies also employ automated gripping equipment such as robotic arms to grasp and transfer the small hardware part 1. However, due to the small size of the hardware part 1 and the corresponding small size of the stamping and forming dies, existing robotic arms struggle to accurately place the hardware part 1 into the stamping and forming dies. In particular, the two side plates 12 of the hardware part 1 are curved, making them prone to swaying and tilting during handling. To solve this technical problem, secondary positioning is required after grasping, which reduces the feeding efficiency to some extent and increases the complexity of the overall structure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0029] See appendix Figure 1 , 2 As shown, an automatic stamping feeding device includes two vertically arranged upright plates 21 and a support plate 22 that is horizontally fixed on the two upright plates 21 by bolts.

[0030] See appendix Figure 4 , 5 As shown, a positioning block 31 is slidably disposed on the support plate 22 along its length. Specifically, the positioning block 31 includes a support block 33 slidably disposed on the support plate 22 via an existing first slide rail slider assembly 32, and a vertical block 34 vertically fixedly installed on the upper end face of the support block 33. Two parallel contour grooves 341 are formed on the upper end face of the vertical block 34, and a small hardware component 1 can be placed in each contour groove 341. The shape of the contour groove 341 matches the shape of the small hardware component 1, that is, the lower end face of the hardware component body 11 abuts against the bottom of the contour groove 341, and the arc-shaped outer side of the side plate 12 abuts against the wall of the contour groove 341.

[0031] A transverse drive cylinder 36 is bolted to the support plate 22 on one side of the support block 33. The transverse drive cylinder 36 is arranged along the length of the support plate 22. The guide rod of the transverse drive cylinder 36 is fixedly connected to the support block 33 through a floating joint. Thus, when the guide rod of the transverse drive cylinder 36 extends or retracts, it can drive the positioning block 31 to slide back and forth along the length of the support plate 22.

[0032] To position one end of the small hardware component 1, in this embodiment, a contour groove 341 extends through the vertical block 34 along its width. A baffle 35 is bolted to one side of the vertical block 34, with the upper surface of the baffle 35 higher than the bottom of the contour groove 341. Therefore, when the small hardware component 1 is pushed within the contour groove 341, one end face of it can abut against the baffle 35, thereby positioning the end of the small hardware component 1.

[0033] See Figure 3 As shown, a guide plate 41 is provided on the other side of the upright block 34. The guide plate 41 is horizontally fixed on the support frame 42. Two guide grooves 411 corresponding to the contour groove 341 are opened on the upper end surface of the guide plate 41 along its length direction. The cross-sectional shape of the guide groove 411 can be the same as the cross-sectional shape of the contour groove 341, so as to facilitate the small hardware part 1 to move forward in the guide groove 411 and enter the contour groove 341 from the guide groove 411.

[0034] One end of the guide groove 411 is positioned opposite to the contour groove 341, and the other end can connect to existing circular and linear vibratory feeding equipment. In this embodiment, when the guide rod of the lateral drive cylinder 36 retracts, it can drive the positioning block 31 to slide, thereby allowing the two contour grooves 341 to connect with the two guide grooves 411, so that the small hardware part 1 can enter the contour groove 341 from the guide groove 411 under the push of the linear vibratory feeding equipment. When the guide rod of the lateral drive cylinder 36 extends, the two contour grooves 341 and the two guide grooves 411 are misaligned, and the small hardware part 1 cannot enter the contour groove 341 from the guide groove 411.

[0035] To prevent the small hardware component 1 from detaching from the guide groove 411 when it is pushed within the guide groove 411, in this embodiment, a cover plate 43 is bolted to the end face of the guide plate 41. To further guide the small hardware component 1 within the guide groove 411, a guide strip 44 is bolted to the lower end face of the cover plate 43 along its length. The guide strip 44 is horizontally inserted into the guide groove 411 above the small hardware component 1, meaning that the guide strip 44 is inserted into the guide groove 411 and also between the two side plates 12, thereby guiding the small hardware component 1 during transport.

[0036] Furthermore, a clearance groove 431 is provided through both the cover plate 43 and the guide strip 44. A bracket 45 is fixedly connected to the guide plate 41 by bolts, and a detection camera 46 is installed on the bracket 45, positioned above the clearance groove 431. The detection camera 46 is connected to an existing controller, and transmits the image captured by the detection camera 46 below the clearance groove 431 to the controller, which then determines whether there is a shortage of material in the guide groove 411.

[0037] In order to position the other end face (i.e. the side near the guide plate 41) of the small hardware part 1 in the contour groove 341, a positioning plate 51 is provided on the other side of the upright block 34. The positioning plate 51 is vertically set and in order to position the small hardware part 1 in the two contour grooves 341, a positioning plate clearance groove 411 is provided on the upper part of the positioning plate 51. When the guide rod of the transverse drive cylinder 36 extends, the positioning plates 51 on both sides of the positioning plate clearance groove 411 can abut and position the small hardware part 1 in the contour groove 341.

[0038] To avoid interference between the guide plate 41 and cover plate 43 and the positioning plate 51, a guide plate clearance groove 412 is provided at one end of the guide plate 41 and cover plate 43 near the upright block 34. The guide plate clearance groove 412 extends through the guide plate clearance groove 412. The positioning plate 51 on the side of the positioning plate clearance groove 411 near the transverse drive cylinder 36 can slide through the guide plate clearance groove 412.

[0039] In order to enable the positioning plate 51 to abut against and disengage from the small hardware part 1 in the contour groove 341, a support block through groove 331 is provided on the support block 33 along its width direction. A connecting block 52 is slidably inserted through the support block through groove 331. The connecting block 52 is fixedly connected to the lower part of the positioning plate 51. A sliding sleeve 53 is fixedly connected to the lower end face of the support block 33. A sliding rod 54 is slidably inserted through the sliding sleeve 53 along the width direction of the support block 33. One end of the sliding rod 54 is fixedly embedded in the lower part of the connecting block 52, and the other end is fixedly connected to the guide rod of the positioning cylinder 55 through a floating joint or other structure. The positioning cylinder 55 is fixedly connected to the lower end face of the support plate 22 along the width direction of the support plate 22.

[0040] The above structure enables the positioning of the two ends of the small hardware 1 in the contour groove 341. Since the side plate 12 is a curved structure, the small hardware 1 may deflect in the contour groove 341. Therefore, the small hardware 1 needs to be positioned horizontally.

[0041] See Figure 4 , 5 As shown in Figure 6, a fixing plate 61 is fixedly connected to the positioning block 31 by bolts. A longitudinal drive cylinder 62 is fixedly connected to the fixing plate 61 along the width direction of the support plate 22. A connecting block 63 is fixedly connected to the guide rod of the longitudinal drive cylinder 62 by a floating joint. The connecting block 63 is slidably mounted on the fixing plate 61 via the second slide rail slider assembly 65. Two pressure plates 64 are horizontally fixedly connected to the connecting block 63 by bolts. The two end faces of the pressure plates 64 match the shape of the small hardware part 1. The two end faces of the pressure plates 64 have a smooth transition. The pressure plates 64 can slide inside the small hardware part 1, that is, the lower end face of the pressure plates 64 can fit against the inner side of the two side plates 12. The longitudinal drive cylinder 62 can drive the pressure plate 64 to move above the contour groove 341 or to the side of the positioning block 31 away from the guide plate 41. That is, when the guide rod of the longitudinal drive cylinder 62 extends, it can drive the two pressure plates 64 to be inserted between the two side plates 12 of the small hardware part 1, thereby positioning the small hardware part 1 in the horizontal direction. When the guide rod of the longitudinal drive cylinder 62 retracts, the pressure plate 64 can be completely removed from above the small hardware part 1, so that existing transfer equipment such as robotic arms can pick up the small hardware part 1.

[0042] It should be noted that, in order to allow the pressure plate 64 to be inserted between the two side plates 12, the upper end surface of the baffle 35 is higher than the upper end surface of the hardware body 11 so as to block and position it, and the upper end surface of the baffle 35 is lower than the upper end surface of the side plate 12 so that the pressure plate 64 can be inserted between the two side plates 12 from above the baffle 35.

[0043] The working principle and process of this embodiment are as follows:

[0044] See Figure 1As shown, the left side of the guide plate 41 of this utility model is connected to an existing circular and linear vibratory feeding device. The small hardware part 1 is fed into the guide groove 411 of the guide plate 41 through the device. The small hardware part 1 is pushed forward under the guidance of the guide bar 44.

[0045] The guide rod of the lateral drive cylinder 36 retracts, causing the positioning block 31 to slide, so that the two contour grooves 341 are aligned and connected with the two guide grooves 411. The small hardware parts 1 in the guide grooves 411 are pushed into the two contour grooves 341 respectively. After that, the guide rod of the lateral drive cylinder 36 extends, causing the contour grooves 341 and guide grooves 411 to be misaligned, so that the small hardware parts 1 in the guide grooves 411 can no longer enter the contour grooves 341. The guide rod of the positioning cylinder 55 retracts to drive the positioning plate 51 to move toward the upright block 34 and abut against one end of the hardware body 11 of the small hardware parts 1 in the two contour grooves 341, and make the other end of the hardware body 11 abut against the baffle 35, thereby positioning both ends of the hardware body 11.

[0046] The guide rod of the longitudinal drive cylinder 62 extends to drive the pressure plate 64 to be inserted between the two side plates 12 of the small hardware part 1, thereby further positioning the small hardware part 1; then the pressure plate 64 is disengaged from the small hardware part 1 under the drive of the longitudinal drive cylinder 62, and the positioning plate 51 is disengaged from the small hardware part 1 under the drive of the positioning cylinder 55, thus completing the positioning of the small hardware part 1 in the contour groove 341. After that, existing robotic arms and other equipment can suck away the positioned small hardware part 1.

[0047] By repeating the above process, batch feeding and positioning of small hardware parts 1 can be achieved.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
