[0055] Embodiment one

[0056] The shape and structure of the driving mechanism will be described in detail as follows:

[0057] In the optional scheme of the embodiment of the present application, the driving assembly comprises a rotary driving piece 200, the transmission assembly comprises a belt transmission assembly 300, a first connecting assembly and a second connecting assembly; the rotary driving piece 200 is in transmission connection with the input end of the belt transmission assembly 300; the output end of the belt transmission assembly 300 is connected with the first connecting assembly and the second connecting assembly respectively, so as to drive the first connecting assembly and the second connecting assembly to move towards each other or away from each other; the first connecting assembly is in sliding fit with a first guide groove 111 in the plurality of guide grooves 110, the second connecting assembly is in sliding fit with a second guide groove 112 in the plurality of guide grooves 110, and the inclination directions of the first guide groove 111 and the second guide groove 112 are opposite.

[0058] Specifically, the rotating driving member 200 is arranged as a motor, an output shaft of the motor is connected with the belt transmission assembly 300, the transmission belt 310 in the belt transmission assembly 300 is respectively in transmission connection with the first connecting assembly and the second connecting assembly, for driving the first connecting assembly and the second connecting assembly to move in the direction of approaching or moving away from each other. The first connecting assembly is in sliding fit with the first guide groove 111, the second connecting assembly is in sliding fit with the second guide groove 112, and the inclination directions of the first guide groove 111 and the second guide groove 112 are opposite, and from top to bottom, the first guide groove 111 and the second guide groove 112 are inclined in the direction of moving away from each other, as another arrangement mode, from top to bottom, the first guide groove 111 and the second guide groove 112 can also be inclined in the direction of approaching each other.

[0059] When the motor drives the first connecting assembly and the second connecting assembly to move in the direction of approaching or moving away from each other through the belt transmission assembly 300, the guide member 100 is driven to move linearly and reciprocally along the first direction a, so as to realize the driving of the guide member 100. In addition, the first connecting assembly and the second connecting assembly are driven through the belt transmission assembly, the belt transmission assembly 300 has simple structure and stable transmission, the movement stability of the first connecting assembly and the second connecting assembly is improved, and the movement stability of the guide member 100 is further improved.

[0060] Specifically, the first connecting assembly comprises a first connecting block 320 and a first suction nozzle assembly 760, one end of the first connecting block 320 is connected with the first section 311 of the transmission belt 310, the other end is connected with the first suction nozzle assembly 760, and the first suction nozzle assembly 760 is in sliding fit with the first guide groove 111; the second connecting assembly comprises a second connecting block 330 and a second suction nozzle assembly 770, one end of the second connecting block 330 is connected with the second section 312 of the transmission belt 310, the other end is connected with the second suction nozzle assembly 770, and the second suction nozzle assembly 770 is in sliding fit with the second guide groove 112.

[0061] Specifically, the first connecting block 320 and the second connecting block 330 are arranged as a connecting rod, and the first connecting block 320 and the second connecting block 330 are connected with each other through a connecting rod body 340. Figure 1For example, the first suction nozzle assembly 760 is located at the rightmost side of the plurality of suction nozzle assemblies 700, the first connecting block 320 is connected with the first suction nozzle assembly 760 for driving the first suction nozzle assembly 760 to move along the horizontal direction; the second suction nozzle assembly 770 is located at the leftmost side of the plurality of suction nozzle assemblies 700, the second connecting block 330 is connected with the second suction nozzle assembly 770 for driving the second suction nozzle assembly 770 to move along the horizontal direction, and the moving direction of the second suction nozzle assembly 770 is opposite to that of the first suction nozzle assembly 760. Because the suction nozzle assembly 700 is in sliding fit with the guide groove 110, when the first suction nozzle assembly 760 and the second suction nozzle assembly 770 are forced to move, the suction nozzle assembly 700 exerts force on the side wall of the guide groove 110, driving the guide 100 to move along the first direction a; when the guide 100 moves, the suction nozzle assembly 700 in sliding fit with the guide groove 110 at the middle position is driven to move along the horizontal direction. For example, when the first connecting block 320 and the second connecting block 330 move in the direction away from each other, the first suction nozzle assembly 760 and the second suction nozzle assembly 770 are driven to move in the direction away from each other, and then the guide 100 is driven to move upward; when the guide 100 moves upward, the guide groove 110 guides the corresponding suction nozzle assembly 700 to move, realizing that the plurality of suction nozzle assemblies 700 change from being located at the first end of the corresponding guide groove 110 to being located at the second end of the corresponding guide groove 110. Correspondingly, when the first connecting block 320 and the second connecting block 330 move in the direction close to each other, the first suction nozzle assembly 760 and the second suction nozzle assembly 770 are driven to move in the direction close to each other, and then the guide 100 is driven to move downward; when the guide 100 moves downward, the guide groove 110 guides the corresponding suction nozzle assembly 700 to move, realizing that the plurality of suction nozzle assemblies 700 change from being located at the second end of the corresponding guide groove 110 to being located at the first end of the corresponding guide groove 110.

[0062] The guide groove 110 is in the shape of a straight line, and the guide groove 110 is arranged at an angle with the first direction a.

[0063] Specifically, the guide groove 110 is provided with two groups, the two groups of guide grooves 110 are symmetrical along the first axis, and the first axis extends along the first direction a; the adjacent two guide grooves 110 in the same group are different in the angle with the first direction a, realizing that the inclined directions of the two guide grooves 110 located at the two sides of the plurality of guide grooves 110 are opposite.

[0064] The guide grooves 110 are linearly arranged, and the included angle between the adjacent two guide grooves 110 in the same group and the first direction a is different, so that the distance between the first ends of the adjacent two guide grooves 110 is different from the distance between the second ends. The first guide groove 111 is located at the rightmost side of the plurality of guide grooves 110, and the second guide groove 112 is located at the leftmost side of the plurality of guide grooves 110.

Because the included angle between the first guide groove 111 and the second guide groove 112 and the first direction a is the largest, the first nozzle assembly 760 is more likely to apply force to the side wall of the first guide groove 111, and the second nozzle assembly 770 is more likely to apply force to the side wall of the second guide groove 112, so that the movement of the guide piece 100 is more easily driven.

[0065] The belt transmission assembly 300 comprises a transmission belt 310. The transmission belt 310 comprises a first section 311 and a second section 312. The first section 311 and the second section 312 are arranged in parallel and at intervals.

[0066] Specifically, the belt transmission assembly 300 comprises a first pulley 340, a second pulley 350, a third pulley, a fourth pulley 360, a synchronous belt 370, and a transmission belt 310. The first pulley 340 is connected with the output shaft of the motor. The second pulley 350 is connected with the first pulley 340 through the synchronous belt 370. The third pulley is coaxially arranged with the second pulley 350 and is connected with the fourth pulley 360 through the transmission belt 310.

The first section 311 and the second section 312 are both arranged in the shape of a long strip, and the length directions of the first section 311 and the second section 312 are both arranged along the second direction b. The first section 311 is connected with the first connecting block 320, and the second section 312 is connected with the second connecting block 330.

[0067] The motor drives the first pulley 340 to rotate. The first pulley 340 drives the second pulley 350 to rotate through the synchronous belt 370. The third pulley rotates coaxially with the second pulley 350 and drives the fourth pulley 360 to rotate through the transmission belt 310. When the third pulley and the fourth pulley 360 rotate, the transmission belt 310 moves along the length direction of the transmission belt 310. The movement directions of the first section 311 and the second section 312 are opposite, so that the first connecting block 320 and the second connecting block 330 connected therewith move towards each other or away from each other, thereby driving the guide piece 100 to move along the first direction a, and changing the distance between the adjacent two nozzle assemblies 700.

When the motor drives the first gear to rotate, the first gear drives the second gear to rotate, and the rotating direction of the second gear is opposite to that of the first gear, the first gear drives the first rack to move, the second gear drives the second rack to move, and the moving direction of the first rack is opposite to that of the second gear, so as to realize the driving of the first connecting block 320 and the second connecting block 330 to move in opposite directions.

[0080] Embodiment two

[0081] The driving assembly comprises a linear driving piece 400 and a transmission plate 500; the output end of the linear driving piece 400 is connected with the transmission plate 500, so as to drive the transmission plate 500 to move linearly and reciprocally along the first direction a; the transmission plate 500 is connected with the guide piece 100.

[0082] Specifically, referring to Figure 5 and Figure 6The linear driving member 400 is provided as a cylinder, and the piston of the cylinder is connected with the transmission plate 500. The transmission plate 500 is detachably connected with the guide member 100 through the guide member 100 by screwing and threading.

[0083] The piston of the cylinder is connected with the transmission plate 500, and the cylinder can drive the transmission plate 500 to linearly reciprocate along the first direction a. The transmission plate 500 is connected with the guide member 100, and the transmission plate 500 drives the guide member 100 to linearly reciprocate along the first direction a. The guide groove 110 is in sliding fit with the suction nozzle assembly 700, so that when the guide member 100 moves, the side wall of the guide groove 110 drives the suction nozzle assembly 700 to move along the horizontal direction, thereby changing the distance between the two adjacent suction nozzle assemblies 700.

[0084] The driving mechanism further comprises a guide assembly 600, which comprises a sliding rail 610 and a sliding block 620. The sliding rail 610 is arranged along the first direction a. The sliding block 620 is indirectly connected with the guide member 100 and is in sliding fit with the sliding rail 610.

[0085] Specifically, referring to Figure 6 The upper surface of the transmission plate 500 is provided with a groove, and the piston of the cylinder is connected with the bottom wall of the groove. The end surface of the transmission plate 500 is connected with the guide member 100, and the inner surface is connected with the sliding block 620. The sliding block 620 is in sliding connection with the sliding rail 610, thereby indirectly connecting the sliding block 620 with the guide member 100.

[0086] The sliding block 620 is in sliding fit with the sliding rail 610 and is indirectly connected with the guide member 100, thereby guiding the movement direction of the guide member 100 and improving the movement stability of the guide member 100.

[0087] The shape and structure of the guide member 100 will be described in detail as follows:

[0088] The guide member 100 is provided with a plurality of guide grooves 110, and the plurality of guide grooves 110 are arranged at intervals along the second direction b. The distance between the first ends of the two adjacent guide grooves 110 is different from the distance between the second ends.

[0089] Because the distance between the first ends of the two adjacent guide grooves 110 is different from the distance between the second ends, when the driving assembly drives the guide member 100 to move through the transmission assembly, the two adjacent suction nozzle assemblies 700 change from being located at the first ends of the corresponding guide grooves 110 to being located at the second ends of the corresponding guide grooves 110, and the distance between the two adjacent suction nozzle assemblies 700 changes. By replacing different guide members 100, the material taking and placing device can be compatible with different models of material trays, thereby increasing the application range of the equipment.

[0090] The distance between the first ends of two adjacent guide grooves 110 is a first distance, and the distance between the second ends of two adjacent guide grooves 110 is a second distance; any two first distances are equal, and at least two second distances are not equal.

[0091] Specifically, referring to Figure 7 The guide 100 is provided in a flat plate shape, and the guide grooves 110 penetrate through the thickness direction of the guide 100. The distance between the two ends of two adjacent guide grooves 110 is matched with the spacing of the tray. In this embodiment, the first distance is set to 11 mm; the second distance includes 28.5 mm and 31.5 mm, and the two distances are alternately arranged.

[0092] At least two second distances are not equal, and when the suction nozzle assembly is located at the second end of the guide groove 110, it can be applied to different models of trays.

[0093] As an embodiment, the guide groove 110 is provided in a straight line shape, and the guide groove 110 is provided at an angle with the first direction a. Specifically, the angles between the two adjacent guide grooves 110 and the first direction a are different, and the inner walls of the two ends of the guide groove 110 are provided in an arc shape.

[0094] The inner walls of the two ends of the guide groove 110 are provided in an arc shape, which increases the contact area between the suction nozzle assembly 700 and the guide groove 110, and improves the stability of the suction nozzle assembly 700 when taking and placing the material.

[0095] As another embodiment, the guide groove is provided in a bent shape, specifically including a first buffer section 113, a guide section 114, and a second buffer section 115; the first buffer section 113 is in communication with one end of the guide section 114, and the second buffer section 115 is in communication with the other end of the guide section 114; a plurality of first buffer sections 113 and a plurality of second buffer sections 115 are arranged in parallel and spaced apart along the second direction b.

[0096] Specifically, the first buffer section 113 and the second buffer section 115 are both provided in a straight line, and the length direction is provided along the first direction a. Further, the ends of the plurality of first buffer sections 113 away from the guide section 114 are flush, and the ends of the plurality of second buffer sections 115 away from the guide section 114 are flush, so that when the suction nozzle assembly 700 is located at the end of the guide groove 110, the plurality of suction nozzle assemblies 700 can be fitted with the end of the corresponding guide groove 110, and the stability of the suction nozzle assembly 700 when taking and placing the material is improved.

[0097] The two ends of the guide section 114 are communicated with the first buffer section 113 and the second buffer section 115 respectively, so that the suction nozzle assembly 700 can move between the first buffer section 113 and the second buffer section 115. The guide groove 110 includes the first buffer section 113 and the second buffer section 115. When the plurality of suction nozzle assemblies 700 enter the corresponding first buffer section 113, the distance between any two adjacent suction nozzle assemblies 700 can be equalized. When the plurality of suction nozzle assemblies 700 enter the corresponding second buffer section 115, the distance between any two adjacent suction nozzle assemblies 700 can be changed. When the distance between any two adjacent suction nozzle assemblies 700 is changed, even if the suction nozzle assembly 700 does not move to be in contact with the end surface of the guide groove 110, the distance between any two adjacent suction nozzle assemblies 700 can be ensured to be consistent with the tray.

[0098] In an optional embodiment of the present application, the guide section 114 can be arranged as follows, or on the basis of the arrangement of the first buffer section 113 and the second buffer section 115, the guide section 114 can be arranged as follows:

[0099] Specifically, the guide section 114 is arranged in a straight line and is arranged at an angle with the first buffer section 113 and the second buffer section 115 respectively.

[0100] Specifically, the widths of the guide section 114, the first buffer section 113 and the second buffer section 115 are equal. Because the straight line distance between two points on the same surface is the shortest, when the guide section 114 is arranged in a straight line, the cam 710 of the suction nozzle assembly 700 can move from the first end to the second end of the guide groove 110 through the shortest distance, thereby accelerating the distance changing efficiency. Of course, the guide section 114 can be arranged in other shapes, such as a bent shape or an S shape, which should also be within the protection scope of the present application.

[0101] The two ends of the guide section 114 are connected with the first buffer section 113 and the second buffer section 115 respectively.

[0102] In the first embodiment, please refer to Figure 7 The guide section 114 is connected with the first buffer section 113 and the second buffer section 115 through a circular arc.

[0103] In the second embodiment, please refer to Figure 8The guiding section 114 comprises an arc-shaped guiding part 117, a first arc-shaped connecting part 118 and a second arc-shaped connecting part 119; two ends of the arc-shaped guiding part 117 are connected with the first arc-shaped connecting part 118 and the second arc-shaped connecting part 119 respectively, and one end of the first arc-shaped connecting part 118 away from the arc-shaped guiding part 117 is connected with the first buffer section 113, and one end of the second arc-shaped connecting part 119 away from the arc-shaped guiding part 117 is connected with the second buffer section 115; the first arc-shaped connecting part 118, the arc-shaped guiding part 117 and the second arc-shaped connecting part 119 are connected in a sinusoidal curve shape, and the concave directions of the first arc-shaped connecting part 118 and the second arc-shaped connecting part 119 are opposite.

[0104] Specifically, when the first arc-shaped connecting part 118 is concave to the right, the second arc-shaped connecting part 119 is concave to the left; when the first arc-shaped connecting part 118 is concave to the left, the second arc-shaped connecting part 119 is concave to the right, and the first arc-shaped connecting part 118 and the second arc-shaped connecting part 119 are divided into positions at the peaks and valleys of the sinusoidal curve.

[0105] The first arc-shaped connecting part 118, the arc-shaped guiding part 117 and the second arc-shaped connecting part 119 are connected in a sinusoidal curve shape, so that the nozzle assembly 700 can smoothly transition between the first buffer section 113, the guiding section 114 and the second buffer section 115, avoiding rapid changes in speed during movement and causing the nozzle assembly 700 to shake violently or collide and press the inner wall of the guide groove 110.

[0106] The taking and placing device provided in the embodiment of the application comprises the driving mechanism in the first embodiment, and therefore has all the beneficial effects of the first embodiment, which will not be described herein.

[0107] The taking and placing device further comprises a plurality of nozzle assemblies 700, and the plurality of nozzle assemblies 700 are in one-to-one sliding fit with the plurality of guide grooves 110 in the driving mechanism.

[0108] Specifically, the nozzle assembly 700 is provided in plurality, and the plurality of nozzle assemblies 700 are arranged in parallel and at intervals along the second direction b.

[0109] When the driving assembly comprises the rotary driving member 200, the driving assembly and the transmission assembly are provided in one, and the guide member 100 is provided in two, the two guide members 100 are fitted with two ends of the nozzle assembly 700 respectively, and the two guide members 100 move synchronously, avoiding the nozzle assembly 700 from being skewed and stuck in the guide groove 110 when moving.

[0110] When the driving assembly comprises the linear driving member 400, the driving assembly, the transmission assembly and the guide member 100 are provided in two, and the two guide members 100 are fitted with two ends of the nozzle assembly 700 respectively. Figure 5 and Figure 6Two transmission assemblies are respectively located at two sides of the guide piece 100, one end of one of the transmission assemblies is connected with the first end of the two guide pieces 100, and the other end of the transmission assembly is connected with the second end of the two guide pieces 100. The two ends of the other transmission assembly are respectively connected with the second ends of the two guide pieces 100. The two transmission assemblies are connected with the two ends of the guide piece 100, and the two transmission assemblies move synchronously to drive the guide piece 100 to move linearly along the first direction a, so that the guide piece 100 is prevented from being inclined during movement, and the suction nozzle assembly 700 is prevented from being clamped in the guide groove 110, and the movement flow field of the suction nozzle assembly 700 is affected.

[0111] The suction nozzle assembly 700 comprises a suction nozzle body and a cam 710. The cam 710 is arranged on the side of the suction nozzle body facing the guide groove 110, and the cam 710 is inserted into the guide groove 110 and is in sliding fit with the guide groove 110.

[0113] The cross section of the cam 710 is circular, the cam 710 is inserted into the guide groove 110, and the outer peripheral wall of the cam 710 abuts against the side wall of the guide groove 110. When the guide piece 100 moves along the first direction a, the side wall of the guide groove 110 generates a force on the cam 710, so as to drive the suction nozzle assembly 700 to move along the second direction b. When the cam 710 moves in the guide groove 110, the cam 710 rolls along the inner wall of the guide groove 110, and the rolling friction is generated between the cam 710 and the guide groove 110, so that the resistance of the cam 710 during movement is reduced, and the movement of the guide piece 100 and the suction nozzle assembly 700 is smoother.
