Among them, the output end of the reciprocating drive member 200 can reciprocate along a first direction; the moving member 300 is slidably arranged on the base 100 along the first direction; the rotating member 400 extends along a second direction perpendicular to the first direction, and the rotating member 400 is arranged on the moving member 300, and is arranged to rotate around its own axis; the picking component 500 is arranged at one end of the rotating member 400, and can rotate synchronously with the rotating member 400; the connecting component 600 includes a first connecting member 610 and a second connecting member 620, one end of the first connecting member 610 and one end of the second connecting member 620 are hinged, and the other end of the first connecting member 610 is connected to the rotating member 400, and is relatively fixed to the rotating member 400 at least in the circumferential direction, and can rotate synchronously with the rotating member 400; the other end of the second connecting member 620 is hinged to the base 100.

[0041] The first direction is the front-to-back direction, and the second direction is the up-down direction.

[0042] With the help of the above-mentioned setting, in the process of the reciprocating driving member 200 driving the moving member 300 to reciprocate along the first direction, the first connecting member 610 and the second connecting member 620 in the connecting assembly 600 can drive the rotating member 400 to rotate relative to the moving member 300, thereby saving a driving member, reducing production and use costs, and making the control logic simpler.

[0043] In some embodiments, the rotating member 400 is disposed on the moving member 300 and is arranged to rotate around its own axis and to move back and forth along its own axis to drive the picking component 500 to rise and fall synchronously, thereby achieving the picking and placing of the workpiece 1000 and avoiding interference with other structures during the transfer process along the first direction.

[0044] It should be noted that both the first connector 610 and the second connector 620 are rod-shaped structures, and the angle between the two is always less than 180°, so as to drive the rotating member 400 to rotate. In some embodiments, the length of the first connector 610 or the second connector 620 is adjustable to adjust the initial angle and the final angle of the rotating member 400 to adapt to different workpieces 1000. Exemplarily, the second connector 620 includes a front end rod, an intermediate sleeve and a rear end rod, one end of the front end rod is provided with a thread on the outer periphery, and the other end is hinged to the first connector 610, one end of the rear end rod is provided with a thread on the outer periphery, and the other end is hinged to the base 100, the intermediate sleeve is provided with an internal thread, and the threads at both ends have different rotation directions, one end of the intermediate sleeve is sleeved on one end of the front end rod and the threads are matched, and the other end of the intermediate sleeve is sleeved on one end of the rear end rod and the threads are matched. The front end rod and the rear end rod are moved closer or farther away from each other by screwing the intermediate sleeve, so that the length of the second connector 620 is adjustable and the adjustment speed is fast.

[0045] In some embodiments, a first rotation hole is provided at one end of the second connecting member 620, and the connecting assembly 600 further includes a first pin 630 extending along the second direction, the first pin 630 is fixedly connected to the first connecting member 610, and at least partially located in the first rotation hole, and the second connecting member 620 is located on the upper side of the first connecting member 610. This arrangement enables the first connecting member 610 and the second connecting member 620 to rotate smoothly, and the second connecting member 620 is supported by the first connecting member 610, which can save the structure of the upper end of the first pin 630 being provided with a crimping connection to the second connecting member 620, and is more convenient for installation.

[0046] In order to avoid interference and improve the smoothness of movement, the base 100 includes a base 110 and a support member 120 protruding from the base 110, the support member 120 is in the shape of a rod, and the second connecting member 620 is hinged to one end of the support member 120 away from the base 110. The connecting assembly 600 also includes a second pin 640, and the other end of the second connecting member 620 is provided with a second rotation hole; the second pin 640 is fixedly connected to the support member 120 and is at least partially located in the second rotation hole. In the second direction, the relative position of the second connecting member 620 and the second pin 640 is adjustable.

[0047] In other embodiments, the length of the second pin 640 is adjustable. The matching accuracy requirement between the first connecting member 610 and the support member 120 in the second direction is reduced, thereby reducing the processing cost. In addition, the above arrangement enables the first connecting member 610 and the second connecting member 620 to be raised and lowered synchronously with the rotating member 400. Furthermore, in order to realize the picking and placing of the workpiece 1000, the rotating member 400 can also reciprocate along the second direction relative to the moving member 300, and the rotating driving member (not shown in the figure) is installed on the moving member 300, and its output end can reciprocate along the second direction, and is transmission-connected to the rotating member 400.

The connecting assembly 600 also includes a fastening screw, which passes through the mounting hole and is screwed into the threaded hole, so that the first connecting portion and the second connecting portion are close to and clamp the rotating member 400.

[0049] In some embodiments, the second connecting member 620 is rod-shaped, and is provided with a plurality of second rotation holes, which are arranged at intervals along the extension direction of the second connecting member 620.

In order to ensure good rotation between the two, in some embodiments, the transfer device further includes a bearing 410, and the rotating member 400 and the moving member 300 are rotationally connected through the bearing 410.

[0054] In other embodiments, in order to reduce energy consumption, the support frame 700 structure can be saved to avoid driving the entire base 100 to lift and lower. Specifically, the rotating member 400 can be set to rotate relative to the moving member 300 and reciprocate in the second direction, and the first connecting member 610 remains stationary in the second direction. Exemplarily, the rotating member 400 includes a fixed portion, a rotating portion and an adjusting portion arranged from bottom to top, the fixed portion is used to fix the pickup assembly 500, the moving member 300 is provided with a rotating hole, the rotating member 400 is arranged in the rotating hole through the rotating portion, and can move up and down relative to the moving member 300, and can rotate around its own axis, the adjusting portion is a prismatic structure, the first connecting member 610 is provided with a sliding channel, the number of edges of the rotating member 400 is the same as the number of sides of the cross section of the sliding channel, the rotating member 400 is located in the sliding channel, and can slide up and down relative to the sliding channel.
