Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the present application belong to the scope of protection of the present application.

The terms "connected", "connected" used in the present application should be broadly understood, for example, it can be fixed connection, or detachable connection; it can be directly connected, or indirectly connected through intermediate components, and the specific meaning of the above terms can be understood by those skilled in the art according to the specific circumstances.

[0034] The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0035] As shown in Figures 1-5 The small component mold jig targeted by the present application is a cuboid frame, and a plurality of molds 19 are arranged in the jig, so that the rapid turnover of a plurality of small components can be realized, and the production efficiency is greatly improved.

[0036] Specifically, the jig comprises at least two square frames 20 welded by galvanized square steel, and support columns 13 at the corners of the two square frames 20, thereby forming a cubic structure. The jig can be conveyed with the conveying belt of the full-automatic production line, and a plurality of molds 19 are arranged in the jig in an array. The openings of the plurality of molds 19 point to the same side of the jig, and the inner cavities of the molds 19 are used for forming small components, so that the transfer and circulation of a plurality of small components can be carried out at the same time, and the production efficiency is improved.

[0037] The jig is also provided with upper ribs and lower ribs. The upper ribs extend along the width direction of the jig, and have a certain width. There are multiple rows of molds 19 in the width direction of the jig, and the upper ribs are respectively located between two adjacent rows of molds 19 along the length direction of the jig. The upper ribs are located above the molds 19 and have a certain width, so as to extend to both sides to stop the two adjacent rows of molds 19, thereby stopping the molds 19 from moving upward. Each row of molds 19 arranged in the width direction of the jig is provided with not less than one lower rib, so as to form a stopping space for limiting the molds 19 by the upper ribs and the lower ribs, thereby ensuring the stability of the molds 19 during the circulation of the jig.

[0038] In view of this, the small automatic component turnover device provided in the application comprises a rotating frame, a clamping mechanism and a driving ring 1. The rotating frame is a columnar frame. Specifically, a plurality of connecting rods 9 are welded between the two driving rings 1 to form the columnar frame. A base 8 is arranged on the tire frame flow path. Corresponding driving roller sets are arranged on the opposite sides in the rotating frame. The two driving roller sets are symmetrical about the center of the rotating frame. The gap between the two driving roller sets is greater than the thickness of the tire frame. When the tire frame is conveyed to the rotating frame by the conveying belt, the driving roller sets are driven by the driving roller sets to pass through the rotating frame.

[0039] The two sides of the same driving roller set are fixed on the two driving rings 1 through the accommodation groove 18. The opening of the accommodation groove 18 faces the inside of the rotating frame, so as to rotationally connect the guide roller 7 and accommodate the transmission chain.

[0040] The two clamping mechanisms correspond to the two driving roller sets respectively. Specifically, the clamping mechanism is arranged on the side away from the driving roller set. The clamping mechanism has a clamping piece 4 passing through the driving roller set. The clamping piece 4 can pass through the driving roller set, so that the tire frame can be clamped or released by the relative movement of the clamping piece 4. In the turnover process, the tire frame can be limited to avoid displacement and falling off.

[0041] The two driving rings 1 are located at the two ends of the rotating frame. The first driving piece corresponding to the driving ring 1 is arranged on the base 8 to drive the rotating frame to roll on the base 8 and drive the tire frame to turn over.

[0042] The tire frame is conveyed along the conveying path by the conveying belt. In the initial state, the two driving roller sets in the rotating frame remain in the horizontal state. At this time, one of the driving roller sets (for easy identification, the lower driving roller set in the initial state is named as the first roller set, and the other driving roller set is the second roller set) is kept on the same horizontal plane as the conveying belt. When the tire frame moves to the inside of the rotating frame along the conveying path, the tire frame is clamped by the two oppositely arranged clamping mechanisms. Then, the rotating frame is driven to rotate by the first driving piece, so as to form the turnover of the tire frame. At this time, the horizontal plane of the other driving roller set (the second roller set) is kept on the same horizontal plane as the conveying belt. The second roller set is started to move the tire frame to the conveying belt behind the rotating frame for subsequent conveying.

[0043] In an optional embodiment, the driving ring 1 protrudes outwardly from the outer circumferential surface of the rotating frame. An arc-shaped groove corresponding to the driving ring 1 is arranged above the base 8. The corresponding angle of the arc-shaped groove should be not less than 90°, so as to axially limit the rotating frame by the driving ring 1 and ensure the stable operation of the rotating frame.

[0044] The depth of the arc-shaped groove is matched with the outward protruding thickness of the driving ring 1.

[0045] In the embodiment, the outer circumferential surface of the driving ring 1 is provided with a plurality of teeth to form a gear ring, and a first driving member is engaged with the external teeth of the driving ring 1 through a driving gear. The first driving member can be a first stepper motor, which is fixed on the base 8 and has a driving gear connected to the main shaft of the first driving member. The driving gear is engaged with the external teeth of the driving ring 1, so that the driving ring 1 can be precisely flipped to ensure the flipping accuracy of the tire rack.

[0046] The driving roller set includes a plurality of guide rollers 7 which are equidistantly distributed along the axis of the rotating frame. The guide rollers 7 are spaced apart, and the gap between adjacent two guide rollers 7 is matched with the diameter of the guide rollers 7. One end of each of the plurality of guide rollers 7 is provided with a sprocket. A second driving member 3 synchronously drives the plurality of guide rollers 7 through a transmission chain, so that the tire rack moves along the driving roller set through the rotation of the guide rollers 7, and then is transferred to the conveying belt at the rear.

[0047] The second driving member 3 is a second stepper motor, which is connected to the conveying chain through the sprocket.

[0048] In an optional embodiment, each clamping mechanism includes a plurality of clamping members 4, and the number of clamping members 4 is three. In this way, one clamping member 4 is arranged at each end and the middle of the tire rack, so as to ensure the stability during flipping. The clamping member 4 has a strip structure, and its length is matched with the length of the guide roller 7 and is opposite to the gap between the guide rollers 7. In this way, the clamping member 4 can clamp the tire rack after passing through the gap between the guide rollers 7. The clamping member 4 is driven by a third driving member 2, which is an electric cylinder, a pneumatic cylinder or an oil cylinder. An installation truss is arranged outside the driving roller set, and the third driving member 2 is fixedly installed on the installation truss. In order to ensure the stability of clamping, guide columns 5 are arranged at both ends of the clamping member 4, and the guide columns 5 are slidably assembled on the installation truss.

[0049] In an optional embodiment, the rotating frame is provided with guide rods 6 corresponding to the two sides of the tire rack. The guide rods 6 are fixed at the middle part of the driving ring 1 through fixing rods, and are located at the midpoint between the two driving roller sets. The length of the guide rod 6 is matched with the length of the rotating frame. The front end of the guide rod 6 is bent to the two sides to form an outwardly expanded guide opening, so that the tire rack is easily guided into the driving roller set. A sensing mechanism is arranged at the rear end of the guide rod 6 to detect the position of the tire rack, so as to determine whether the tire rack reaches the specified position, thereby enabling subsequent clamping and flipping operations.

[0050] In the embodiment, the tire rack is a cuboid frame, and a plurality of molds 19 are arranged in an array in the tire rack. The sensing device supports the columns 13 at the corners of the tire rack.

[0051] The induction mechanism comprises a dial 10 and a fourth driving member 11, wherein the dial 10 is rotationally connected to the rear end of the guide rod 6, the diameter of the dial 10 is substantially the same as that of the guide column, and two corresponding frame flaps are distributed on the outer periphery of the dial 10, the frame flaps are 90° sector plates, so that the frame can be driven to rotate by the pushing of the frame end and the two side supporting columns 13 during the forward pushing of the frame, and the dial 10 is rotated, so as to determine that the frame reaches the designated position.

[0052] Alternatively, the frame end is driven to rotate actively, so that the frame continues to move along the axial direction of the rotating frame. During the frame transfer, there is a certain gap between the driving roller set and the rear transfer belt. In order to make the frame enter the rear transfer belt more smoothly, the frame end is driven to rotate actively, specifically, the supporting column 13 at the corner of the frame is driven.

[0053] The fourth driving member 11 is correspondingly connected to the dial 10 to drive the dial 10 to rotate actively, so as to provide the frame with a certain initial driving force. The fourth driving member 11 is a third stepping motor.

[0054] In the embodiment, the specific position of the dial 10 is detected by the induction member 12. During the rotation of the dial 10, one of the sector plates is moved by the pushing of the frame. When the sector plate is rotated to the position (rotated by 90°), the fourth driving member 11 is started, so that the other sector plate drives the frame to move forward, and the angle of active rotation is also 90°. At this time, the dial 10 returns to the initial position, so as to perform induction on the next frame.

[0055] The position of the dial 10 is inducted by the induction member 12. The induction member 12 is arranged outside the guide rod 6. The induction member 12 can be an infrared sensor, a position sensor or an angle sensor, etc. When the induction member 12 faces the flap, the relative position of the flap is detected. The induction member 12 is correspondingly connected to the control center.

[0056] The control center is a plc control center, and is correspondingly connected to the first driving member, the second driving member 3, the third driving member 2 and the fourth driving member 11, so as to realize automatic control and reverse.

[0057] In the embodiment, the dial 10 is rotationally connected to the rotating shaft 15. The rotating shaft 15 and the dial 10 are provided with a ratchet 16 wheel. The rotating shaft 15 penetrates through the guide rod 6 and is correspondingly connected to the fourth driving member 11.

[0058] Specifically, the dial 10 is provided with a mounting hole corresponding to the rotating shaft 15. The mounting hole is internally provided with a ratchet wheel 14. The outer wall of the rotating shaft 15 is provided with a mounting groove. The inside of the mounting groove is provided with a ratchet 16 which slides along the radial direction of the rotating shaft 15. The bottom of the mounting groove is provided with a spring piece 17, so that the ratchet 16 has potential energy to drive the ratchet wheel 14, thereby forming the ratchet 16 structure.

[0059] The guide rods 6 on both sides of the rotating frame are provided with dials 10, and the dials 10 on the two guide rods 6 are symmetrical to each other.

[0060] A flat surface corresponding to the dial 10 is arranged above the guide rod 6, which facilitates the installation and positioning of the dial 10.

[0061] The guide rod 6 is provided with a through hole corresponding to the rotating connection shaft 15, and the shaft 15 is connected to the driven bevel gear after passing through the guide rod 6. The third stepping motor drives the driven bevel gear through the driving bevel gear, thereby achieving driving.

[0062] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application is within the scope of the claims of the present application.
