As shown in fig. 1 to 3, the present embodiment provides a material transfer device, which includes a base 10, and a first adaptor 20 and a second adaptor 30 disposed on the base 10, wherein the first adaptor 20 and the second adaptor 30 are respectively provided with a first accommodating through hole 22 and a second accommodating through hole 311; the rod-shaped materials 70 are conveyed to the first transfer member 20 from the outside and are vertically accommodated in the first accommodating through hole 22; the second adaptor 30 is arranged below the first adaptor 20 and has a loading position and a discharging position which are horizontally arranged along a first direction (namely, an X direction in the drawing) at intervals, the second adaptor 30 receives the rod-shaped materials 70 on the first adaptor 20 at the loading position, and the rod-shaped materials 70 are vertically accommodated in the second accommodating through hole 311; the material transfer device further comprises a first driving member 40 and a clamping mechanism 50, wherein the first driving member 40 is used for driving the second adaptor 30 to horizontally move from the material loading position to the material discharging position; the gripping mechanism 50 is used for gripping the rod-shaped material 70 on the second adaptor 30 at the discharging position. The rod-shaped material 70 described in this embodiment refers to a material with a certain length, which needs to be kept in a vertical state during transferring and assembling, and may be a solid rod or a hollow tube, and for convenience of description, the rod-shaped material 70 is referred to herein collectively. The material transfer device that this embodiment provided realizes that bar-shaped material 70 shifts through two keysets and the holding through-hole on it, and has guaranteed the vertical of bar-shaped material 70 and placed for final clamp is got mechanism 50 and is carried out the clamp under the vertical state to bar-shaped material 70 and get, in order to accomplish the material assembly, has improved transfer efficiency, can also effectively avoid leaking the emergence of pressing from both sides the phenomenon.

Specifically, referring to fig. 2 and 3, the first adapter 20 includes a first adapter plate 21, the first support seat 11 is disposed on the base 10, and the first adapter plate 21 is disposed on the first support seat 11 to maintain the stable placement of the first adapter plate 21. The first transfer plate 21 is placed vertically, and the first receiving through-hole 22 penetrates the first transfer plate 21 in the vertical direction. Optionally, the first accommodating through hole 22 is divided into a plurality of parts from top to bottom, and the aperture of each part gradually decreases from top to bottom, so that the bar material can easily enter the first accommodating through hole 22 first, and gradually get close to the vertical state under the guidance of the hole wall of the first accommodating through hole 22, and finally keep vertical as much as possible. Further, the rod-shaped materials 70 on the first transfer plate 21 are put in by an external vibration feeding device, which may be a vibration tray, that is, the horizontally stacked rod-shaped materials 70 are fed into the first receiving through hole 22 of the first transfer plate 21 one by vibration.

With continued reference to fig. 2 and 3, the second adaptor 30 includes a second adaptor plate 31 disposed horizontally, a connecting plate 32 disposed at the bottom of the second adaptor plate 31, and a lifting plate 33 slidably disposed on the connecting plate 32 along the vertical direction, and the output end of the first driving member 40 is connected to the connecting plate 32; the second receiving hole 311 penetrates the second adapter plate 31 in the vertical direction, the lifting plate 33 is disposed right below the second receiving hole 311 and can move up and down relative to the second adapter plate 31, and the rod-shaped material 70 located in the second receiving hole 311 is supported on the top end of the lifting plate 33. In specific implementation, at the feeding position, the first accommodating through hole 22 and the second accommodating through hole 311 are aligned, the rod-shaped material 70 falls into the second accommodating through hole 311 from the first accommodating through hole 22, and meanwhile, the bottom end of the rod-shaped material abuts against the top of the lifting plate 33 and is supported in a vertical state by virtue of the lifting plate 33; after the second adaptor 30 moves to the discharging position, the lifting plate 33 rises to lift the rod-shaped material 70 out of the second adaptor plate 31 by a certain height, so that the clamping mechanism 50 can be conveniently clamped; in the ejection process, the rod-shaped material 70 is not separated from the second accommodating through hole 311, so that the second accommodating through hole 311 can play a role in guiding in the vertical direction, and the rod-shaped material 70 is ensured to be vertical. After the clamping mechanism 50 finishes clamping, the first driving member 40 may drive the second adaptor 30 to return to the feeding position, and continue to perform subsequent feeding transfer of the rod-shaped materials 70, and meanwhile, the lifting plate 33 also moves down to the return position, so as to support new rod-shaped materials 70.

A gap in the vertical direction is arranged between the bottom surface of the first adapter plate 21 and the top surface of the second adapter plate 31, and the gap should be as small as possible without affecting the horizontal movement of the second adapter plate 31, so as to ensure that the rod-shaped material 70 smoothly enters the second accommodating through hole 311 from the first accommodating through hole 22; the larger the gap, the more likely the rod-like material 70 is to be deviated when it freely falls, and the rod-like material cannot smoothly enter the second receiving through hole 311. Referring to fig. 2, optionally, a plurality of first receiving through holes 22 are provided at intervals along the second direction (i.e., Y direction in the drawing) on the first adapter plate 21, and correspondingly, a plurality of second receiving through holes 311 are provided at intervals along the second direction on the second adapter plate 31, and the first receiving through holes 22 correspond to the second receiving through holes 311 one to one. The first direction and the second direction are perpendicular to each other in a horizontal plane. The plurality of accommodating through holes are arranged, so that the feeding and transferring of a plurality of rod-shaped materials 70 can be realized at the same time, and the transferring efficiency is improved; meanwhile, since the first accommodating through holes 22 correspond to the second accommodating through holes 311 one to one, no material leakage occurs as long as all the first accommodating through holes 22 are filled with the rod-shaped materials 70 and the rod-shaped materials smoothly enter the second adapter plate 31.

After the rod-shaped materials 70 slide into the second receiving through hole 311 from the first receiving through hole 22, it is ensured that the top surface of the rod-shaped materials 70 is located below the bottom surface of the first adaptor plate 21 so that the first adaptor plate 21 does not interfere with the horizontal movement of the second adaptor 30. Further, it is preferable that the top end of the rod-shaped material 70 is located below the top surface of the first adapter plate 21 after entering the second receiving through hole 311, so as to ensure that the rod-shaped material 70 does not protrude out of the second adapter plate 31, and the first adapter plate 21 naturally does not interfere with the second adapter 30, and at the same time, the gap between the first adapter plate 21 and the second adapter plate 31 can be reduced as much as possible. Further, at the feeding position, the distance between the top surface of the lifting plate 33 and the top surface of the second adapter plate 31 is greater than or equal to the length of the rod-shaped material 70, and the distance between the top surface of the lifting plate 33 and the bottom surface of the second adapter plate 31 is smaller than the length of the rod-shaped material 70, so that the rod-shaped material 70 is prevented from being separated after entering the second accommodating through hole 311, and the top end of the rod-shaped material is prevented from protruding out of the second adapter plate 31. The length of the rod-shaped material 70 is greater than that of the second receiving through hole 311 so that the lifting plate 33 can lift the rod-shaped material 70 out of the second receiving through hole 311; if the length of the rod-like material 70 is equal to or less than the length of the second receiving through hole 311, the rod-like material 70 cannot be ejected even when the lifting plate 33 is lifted up to abut against the second adaptor plate 31. Further, the thickness of the second adapter plate 31 is compressed as much as possible while the rod-shaped material 70 is limited in the vertical direction, and the compactness of the device is improved.

In the present embodiment, the rod-like material 70 has a cylindrical structure, and accordingly, the first receiving through-hole 22 and the second receiving through-hole 311 also have a cylindrical structure. Further, the aperture of the second receiving through-hole 311 is larger than that of the first receiving through-hole 22. For the case where the aperture of the second receiving through-hole 311 is gradually reduced, the aperture herein refers to the smallest aperture of the second receiving through-hole 311. Specifically, the first receiving through hole 22 has a diameter larger than the outer diameter of the rod-like material 70, so that the material can smoothly slide into the first receiving through hole 22 by an external loading device; further, the diameter of the second receiving through hole 311 is equal to the outer diameter of the rod-shaped material 70 or slightly larger than the outer diameter of the rod-shaped material 70, so as to ensure that the material is lifted and gripped in a vertical state as much as possible. It is understood that the diameter of the second receiving through hole 311 is slightly larger than the outer diameter of the rod-shaped material 70, so as to ensure that the material smoothly enters the second receiving through hole 311 from the first receiving through hole 22, and under this condition, the closer the diameter of the second receiving through hole 311 is to the outer diameter of the rod-shaped material 70, the more the material is vertically placed.

Still referring to fig. 2 and 3, the lifting plate 33 is provided with a sensor 35 for detecting whether the rod-shaped material 70 exists in the second accommodating through hole 311, that is, detecting whether a material leakage phenomenon exists, so as to avoid the material leakage of the subsequent clamping mechanism 50. For the second adaptor 30 provided with a plurality of second receiving through holes 311, the corresponding sensors 35 are also provided in plurality and in one-to-one correspondence to detect for each second receiving through hole 311. Alternatively, the mounting member 34 is provided on one side of the lifting plate 33 along the first direction, the connecting plate 32 is connected to the other side, and the sensor 35 is provided on the mounting member 34. Further, referring to fig. 5, the mounting member 34 is provided with a mounting hole 341 penetrating along the first direction, the sensor 35 is disposed in the mounting hole 341, and the height of the mounting hole 341 is higher than the height of the top end of the lifting plate 33, so that the sensor 35 can sense the existence of the rod-shaped material 70 in the second receiving through hole 311 through the mounting hole 341.

Alternatively, the first driving member 40 is an air cylinder, and referring to fig. 2, the main body of the air cylinder is disposed on the base 10 through the second supporting seat 12, and the output end of the air cylinder is connected to the connecting plate 32. Further alternatively, referring to fig. 3, a first guiding structure 36 is provided between the lifting plate 33 and the connecting plate 32 for guiding the movement of the lifting plate 33 in the vertical direction. The first guide structure 36 is a linear guide structure.

The material transfer device further comprises a jacking driving piece for driving the jacking plate 33 to move up and down. In some other embodiments, the jacking actuators also employ cylinders; when the jacking driving piece is the cylinder, the cylinder only needs to move when the second adaptor 30 moves to the discharging position, so that the jacking of the bar can be realized, and the cylinder can not move when the feeding position moves to the discharging position. In this embodiment, referring to fig. 4 and 5, the jacking driving member includes a guide groove 1111 formed on a vertical plane of the base 10 and a cam 331 formed to protrude from the jacking plate 33, the guide groove 1111 extends in a first direction and has a first end and a second end spaced apart from each other in the first direction, the second end has a height greater than that of the first end, and the cam 331 is rollably supported on a groove wall of the guide groove 1111. When the first driving member 40 drives the second adaptor 30 to move from the loading position to the unloading position, the cam 331 moves from the first end to the second end (i.e. moves along the unloading direction), and drives the lifting plate 33 to lift under the support of the slot wall of the guide slot 1111; conversely, when the second adaptor 30 returns from the discharging position to the loading position, the cam 331 moves in the opposite direction along the guide groove 1111, and the lifting plate 33 descends to return to the original position. Further, the first end and the second end of the guiding slot 1111 are smoothly transited to ensure that the jacking is smoothly and slowly completed without causing a jam. The jacking is realized by adopting the pure mechanical matching mode of the cam 331 and the guide groove 1111, the parts needing electric control such as an air cylinder are avoided, the part cost is reduced, and the stable lifting of the jacking plate 33 is realized.

Further, referring to fig. 4, the guide groove 1111 includes an upper groove wall and a lower groove wall that are parallel to each other, and the cam 331 is rolled between the upper groove wall and the lower groove wall, so that the groove wall of the guide groove 1111 is used to accurately limit the cam 331, thereby ensuring smooth completion of the jacking operation. Alternatively, the cam 331 is provided at least one end of the lifting plate 33 in the second direction; the rotational axis of the cam 331 extends in the second direction. Optionally, referring to fig. 3, a guide plate 111 is vertically disposed on the first supporting seat 11, and the guide plate 111 is provided with the guide slot 1111; the guide groove 1111 penetrates the guide plate 111 in the second direction.

Referring to fig. 6, the gripping mechanism 50 includes a gripping member and a second driving member 51 disposed on the base 10, the gripping member includes two jaws 52 disposed opposite to each other along a first direction, and the rod-shaped material 70 can be gripped between the two jaws 52; the second driving member 51 is used for driving the two jaws 52 to move toward or away from each other in the first direction. Alternatively, the second driving member 51 is a pneumatic finger cylinder, and two output ends of the pneumatic finger cylinder are respectively connected with one clamping jaw 52. When the second adaptor 30 moves to the discharging position, the clamping member is located right above the second receiving through hole 311, so that the rod-shaped material 70 can be accurately clamped. Specifically, referring to fig. 7, the clamping jaw 52 includes a clamping jaw body 521 and a clamping groove 522 opened on the clamping jaw body 521, and the rod-shaped material 70 is clamped in the clamping grooves 522 of the two clamping jaws 52 simultaneously. For a cylindrical bar material, the engaging groove 522 is a semicircular structure, and the two jaws 52 can form a complete circle after approaching each other, and the diameter of the complete circle is the same as the outer diameter of the bar material 70, so as to obtain a better clamping effect. When the clamping grooves 522 are of a semicircular structure, if the two clamping jaws 52 cannot be completely closed, the two semicircular clamping grooves 522 cannot be closed, so that the rod-shaped material 70 cannot be clamped effectively, and the material is prone to slipping off. Therefore, referring to fig. 7 and 8, a sliding groove 523 extending along the first direction is formed in a groove wall of the clamping groove 522 of the clamping jaw body 521, the clamping jaw 52 further includes a sliding block 524 arranged in the sliding groove 523 in a sliding manner along the first direction, the sliding block 524 has a third end and a fourth end arranged at an interval along the first direction, the third end of the sliding block 524 is provided with a V-shaped groove 5241, the V-shaped groove 5241 is partially located in the clamping groove 522, an elastic element 525 is arranged between the fourth end of the sliding block 524 and the clamping jaw body 521, and the elastic element 525 is configured to enable the sliding block 524 to have a moving tendency toward the rod-shaped material 70 all the time. In this embodiment, the elastic member 525 is a compression spring. When the rod-shaped material 70 is clamped, referring to fig. 7, the material is directly clamped in the V-shaped groove 5241 of the clamping jaw 52 first, which is equivalent to adding a V-shaped flange in the original semicircular clamping groove 522, and meanwhile, the clamping effect on the rod-shaped material 70 is also improved through the arrangement of the elastic element 525, and the rod-shaped material can be effectively prevented from falling. Optionally, the wall of the V-shaped groove 5241 is smoothly transited to the wall of the sliding block 524 to avoid scratching the rod-shaped material 70. Further, referring to fig. 8, the fourth end of the sliding block 524 extends to both sides along the second direction to form a limiting boss 5242, a limiting step is arranged on the wall of the sliding groove 523, and the sliding block 524 is limited when the sliding block 524 is close to the rod-shaped material 70 along the first direction by the abutting of the limiting boss 5242 and the limiting step, so that the V-shaped groove 5241 is prevented from protruding out of the clamping groove 522 too much.

Further, referring to fig. 6, the material transferring apparatus further includes a driving module 60 for driving the gripping mechanism 50 to move in the vertical direction and the first direction, that is, to adjust the position of the gripping mechanism 50. Since the second adapter 30 is displaced only in the first direction, the position of the rod shaped material 70 in the second direction is not changed, and the gripping device 50 does not need to be adjusted in position in the second direction, provided that the discharge position is located directly above the rod shaped material 70. However, due to the error of the movement of the second adaptor 30 along the first direction, or considering the difference of the discharging positions of different products, and considering that the clamping members cannot interfere with the ejection of the rod-shaped materials 70, the driving module 60 needs to be arranged to realize the adjustment of the clamping mechanism 50 in the first direction and the vertical direction. Specifically, the driving module 60 includes a fourth driving element 62 disposed on the base 10 and a third driving element 61 disposed at an output end of the fourth driving element 62, the output end of the third driving element 61 is connected to the second driving element 51 of the clamping mechanism 50, the third driving element 61 is configured to drive the clamping mechanism 50 to move in the vertical direction, and the fourth driving element 62 is configured to drive the third driving element 61 and the clamping mechanism 50 to move in the first direction.
