DETAILED DESCRIPTION

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention.

[0016] Embodiment: An automatic feeding device for hot riveted parts includes a belt conveyor line 1 and a flip initial positioning component, wherein the flip initial positioning component includes a main frame 2 arranged on the belt conveyor line 1, a material cache component 4 arranged on the front side of the main frame 2, and a material flip positioning component 3 arranged on the rear side of the main frame 2, the material cache component 4 includes a cache lifting cylinder 40, a cache baffle 41 connected to the cache lifting cylinder 40, the cache baffle 41 is connected to the main frame 2 for sliding up and down connection, the cache baffle 41 includes a sliding portion 410 slidingly connected to the main frame 2, a cache blocking portion 411 horizontally arranged at the bottom of the sliding portion 410, the cache blocking portion 411 is provided with a side positioning bar 4111 extending forward, and a rear positioning bar 4110 arranged on the left and right sides of the side positioning bar 4111, and the left and right sides of the side positioning bar 4111 and the left and right sides of the rear positioning bar 4110 are provided with a hot riveting The positioning surface 6 is fitted on the side of the part, and the front ends of both sides of the side positioning strip 4111 are provided with guide surfaces 7, and the positioning surface 6 on the front side of the rear positioning strip 4110 extends obliquely from the front outside of the rear positioning strip 4110 to the tail end of the side positioning strip 4111, and the material flipping and positioning assembly 3 includes a positioning stopper 36 arranged on the belt conveyor line 1, a material picking and lifting cylinder 30 arranged on the main frame 2, a first flipping part 34 arranged on the material picking and lifting cylinder 30, a first vacuum suction cup 35 arranged on the first flipping part 34, a second flipping part 31 arranged on the material picking and lifting cylinder 30, a third flipping part 32 arranged on the second flipping part 31, and a second vacuum suction cup 33 arranged on the third flipping part 32, the rotation axes of the first flipping part 34 and the second flipping part 31 are horizontal, and the rotation axis of the third flipping part 32 is perpendicular to the rotation axis of the second flipping part 31.

[0017] Excess hot-riveted parts are blocked by the part buffer assembly 4, and the hot-riveted parts are positioned and flipped by the part flipping and positioning assembly 3, facilitating accurate material retrieval by the retrieving device. This device sorts and positions incoming hot-riveted parts in batches, reducing the transfer of hot-riveted parts and improving loading efficiency. The guiding surface 7 on the front side of the side positioning bar 4111 and the inclined positioning surface 6 on the front side of the rear positioning bar 4110 facilitate initial alignment of the hot-riveted parts. The first flip member 34, the second flip member 31, and the third flip member 32 can adjust the horizontal orientation of two simultaneously positioned hot-riveted parts, facilitating simultaneous material retrieval by the retrieving device.

[0018] See Figure 3 In order to simplify the structure and improve work efficiency, the first flip member 34, the second flip member 31 and the third flip member 32 are all rotary cylinders with a rotation stroke of 180°.

[0019] See Figure 3The positioning stopper 36 comprises a stopper beam 360 connected to the belt conveyor 1 and guide bars 361 mounted on the stopper beam 360. This facilitates further positioning of the hot-riveted parts and enables precise material removal from the first and second vacuum cups 35 and 33. The three guide bars 361, arranged in sequence, form two guide channels 362. A positioning block 364 extending to the end of the guide channels 362 is located on the front of the stopper beam 360. These positioning blocks 364 and guide channels 362 facilitate automatic further positioning of the hot-riveted parts in conjunction with the belt conveyor 1. A through-beam laser sensor 363 is mounted on the guide bar 361 to detect the presence of product within the guide channels 362, facilitating automatic control.

[0020] See Figure 2 In order to facilitate the adjustment of the position of the cached hot rivets and to facilitate the caching of at least one hot rivet on each side of the side positioning bar 4111 to improve efficiency, a distribution component 5 is also provided on the front side of the main frame 2. The distribution component 5 includes a translation module 50 that moves left and right on the main frame 2, a horizontal rotating part 51 provided on the translation module 50, a suction lifting cylinder 52 provided on the horizontal rotating part 51, and a transfer vacuum suction cup 53 provided on the suction lifting cylinder 52. Reflective laser sensors 54 are provided on both sides of the belt conveyor line 1 for detecting whether there are products in front of the rear positioning bar, so as to facilitate the detection of whether there are materials on both sides of the side positioning bar 4111 and whether the material direction is correct.

[0021] During operation, the belt conveyor line 1 transports hot rivets backward, and the buffer baffle 41 descends to block the hot rivets on the belt conveyor line 1. When there are vacancies for hot rivets on both sides of the side positioning strip 4111, and there are hot rivets arriving behind the unoccupied positions, the distribution assembly 5 moves a hot rivet on the side of the side positioning strip 4111 to the vacant position, while adjusting the direction as needed. When the hot rivets on both sides of the side positioning strip 4111 are fully filled and there are no hot rivets in the guide channel 362, the buffer baffle 41 rises, and the belt conveyor line 1 transports the hot rivets backward into the guide channel 362 until they are blocked and positioned by the positioning block 364. The material flipping and positioning assembly 3 descends to absorb the hot rivets in the guide channel 362, then rises and flips the hot rivets upward 180°. The third flipping member 32 horizontally rotates the hot rivets on the second vacuum suction cup 33 so that the two hot rivets face the same direction.

[0022] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
