So set up, no matter what the turned position is in to the rotating head 310, the encapsulation unit on the rotating head 310 can be just to flying to clap device 400 to can reduce the error that image deformation brought when detecting, thereby improve the accuracy when detecting.

Specifically, during the detection process, the rotating frame 320 only needs to rotate along the Z-axis and the rotating head 310 only needs to rotate along the X-axis, so that all the components on the packaging device 300 can be detected; if the position and the posture of the part are detected to be required to be adjusted, during packaging, the rotating frame 320 adjusts the rotating angle of the Z axis according to the error data acquired by the flying shooting device 400, and meanwhile, the XY driving mechanism also drives the rotating frame 320 to perform position fine adjustment in the XY direction, so that the part can be placed on the workpiece in a normal preset posture.

Referring to fig. 1 and 2, in some embodiments of the present application, the Z-axis driving mechanism 200 includes a lead screw nut assembly 210, a sliding table 220, and a guide rail 230, wherein the sliding table 220 is slidably disposed on the guide rail 230 and connected to the lead screw nut assembly 210; a transmission shaft 510 is rotatably arranged on the sliding table 220 along the Z axis, the rotating frame 320 is connected with the transmission shaft 510, and the sliding table 220 can drive the transmission shaft 510 to move along the Z axis direction; a shaft rotation driving structure 520 for driving the transmission shaft 510 to rotate is further provided on the frame body 100 or the sliding table 220.

It can be understood that the Z-axis driving mechanism 200 is provided as the lead screw nut assembly 210, the guide rail 230 is provided along the Z-axis direction, and the slide table 220 connects the nut on the lead screw nut assembly 210 and the slide table 220, and thus, the movement of the packaging device 300 in the Z-axis direction is stable and the movement precision is high.

Further, a transmission shaft 510 is rotatably arranged on the sliding table 220 along the Z axis, the rotating frame 320 is fixedly arranged at the bottom end of the transmission shaft 510, and when the sliding table 220 reciprocates along the Z axis direction, the sliding table 220 drives the transmission shaft 510 and the rotating frame 320 to move in the Z axis direction together; meanwhile, the shaft rotation driving structure 520 is fixedly arranged on the frame body 100 or the sliding table 220 and is rotationally connected with the transmission shaft 510, but not arranged at the top of the rotating frame 320, and the shaft rotation driving structure 520 drives the transmission shaft 510 to rotate along the Z axis, so as to drive the packaging device 300 to rotate along the Z axis.

Referring to fig. 2, in some embodiments of the present application, a driven structure is disposed on the transmission shaft 510 along the Z-axis direction, a driving structure capable of cooperating with the driven structure is disposed outside the transmission shaft 510, and a shaft rotation driving structure 520 is disposed on the frame body 100 and connected to the driving structure.

It can be understood that the shaft rotation driving structure 520 is disposed on the frame body 100 instead of the sliding table 220, so that the driving load of the Z-axis driving mechanism 200 can be reduced, which is beneficial to increasing the driving speed of the Z-axis driving mechanism 200, and thus the operation speed of the packaging device 300 can be increased.

Specifically, a driven structure is arranged on the transmission shaft 510, a driving structure matched with the driven structure is arranged on the outer side of the transmission shaft 510, and further, the height position of the driving structure is fixed; when the driving structure moves, the driving shaft 510 can be driven to rotate along the Z axis; when the transmission shaft 510 reciprocates along the Z-axis direction, the driving structure can slide along the Z-axis direction relative to the driven structure. In order to realize the motion of the active structure, a connecting member is disposed between the shaft rotation driving structure 520 and the active structure, so that the shaft rotation driving structure 520 drives the transmission shaft 510 to rotate by driving the connecting member to move.

The driving structure and the driven structure are arranged in this way, so that the structure is simple, the mass is small, and the driving load of the shaft rotating driving structure 520 is small, thereby being beneficial to improving the operation speed of the packaging device 300.

Referring to fig. 1, 3 and 4, in some embodiments of the present application, the packaging unit is a suction nozzle 311, the rotary head 310 communicates with the external blowing device 600 and the negative pressure generating device, and a switching structure for enabling the suction nozzle 311 to be at a negative pressure position or a positive pressure position is disposed between the rotary rack 320 and the rotary head 310.

It is understood that the rotary head 310 communicates the external blowing unit 600 and the negative pressure generating unit, and at the same time, an air passage is provided inside the rotary head 310 and can communicate with each suction nozzle 311, so that the suction nozzle 311 can be in a negative pressure position or a positive pressure position to suck or release the parts.

Further, a switching structure for enabling the suction nozzle 311 to be at a negative pressure position or a positive pressure position is disposed between the rotating frame 320 and the rotating head 310, and the switching structure includes a driving switching structure and a driven switching structure. Specifically, the driven switching structure is disposed in the rotary head 310, and the driven switching structure can slide or roll in the rotary head 310 to make the suction nozzle 311 in a negative pressure position or a positive pressure position; meanwhile, the active switching structure is disposed on the rotating frame 320, the active switching structure can rotate or slide relative to the rotating head 310, and the active switching structure and the driven switching structure cooperate with each other, so as to switch the suction nozzle 311 between a negative pressure position or a positive pressure position.

For example, the driving switching structure is a rotating device, and when the driven switching structure is set to roll, the driving switching structure pushes the driven switching structure to roll when rotating, so that the suction nozzle 311 is switched between the negative pressure position and the positive pressure position; under the condition that the driving switching structure is rotationally arranged, the driven switching structure can also be arranged in a sliding manner, and the driving switching structure pushes the driven switching structure to slide when rotating, so that the suction nozzle 311 is switched between the negative pressure position and the positive pressure position.

Furthermore, the active switching mechanism may be a linear sliding device, such as a linear motor, and the driven switching mechanism is slidably disposed, so that the active switching mechanism slidably pushes or pulls the driven switching mechanism to change the suction state of the suction nozzle 311.

Referring to fig. 1, 3, 4 and 5, in some embodiments of the present application, the switching structure includes a shaft structure 331 and a switching valve 332; the switching valves 332 are uniformly disposed on the spin head 310 around the X-axis, each switching valve 332 is disposed corresponding to each suction nozzle 311, and the switching valves 332 can move in the spin head 310 to control the suction nozzles 311 to be at the negative pressure level or the positive pressure level; the shaft structure 331 is rotatably disposed on the rotating frame 320 for driving the switching valve 332 opposite thereto to move.

It can be understood that a plurality of valve cavities 312 are arranged on the rotary head 310 around the X-axis and along the axial direction of the X-axis, the rotary head 310 is communicated with the external air blowing device 600 and the negative pressure generating device, meanwhile, an air passage is arranged inside the rotary head 310, and the air passage and the suction nozzle 311 are respectively communicated with the valve cavities 312.

A switching valve 332 is rotatably or slidably disposed in the valve cavity 312, and a channel is disposed on the switching valve 332, such that when the position of the switching valve 332 in the valve cavity 312 changes, the channel in the switching valve 332 can communicate with an air channel on the rotary head 310, which communicates with the external air blowing device 600 or the negative pressure generating device, so as to make the suction nozzle 311 on the rotary head 310 at a negative pressure position or a positive pressure position.

Specifically, when the spin head 310 rotates around the X-axis, the suction nozzle 311 on the spin head 310 rotates around the X-axis, the rotation track of the suction nozzle 311 is a first circular arc track, and meanwhile, when each switching valve 332 on the spin head 310 is stationary relative to each valve cavity 312, the spin head 310 rotates, each switching valve 332 also rotates around the X-axis, the rotation track of each switching valve 332 is a second circular arc track a, and therefore, the first circular arc track and the second circular arc track a are concentric circles.

It can be understood that the shaft structure 331 is disposed on the rotating frame 320, and it should be understood that the shaft structure 331 is disposed on the cylindrical surface where the second circular arc track a is located, so that the switching valve 332 on the rotating head 310 can rotate to face the shaft structure 331 along with the rotating head 310, so that the shaft structure 331 can cooperate with the switching valve 332 and push the switching valve 332 to rotate or slide in the valve cavity 312, so that the suction nozzle 311 can switch back and forth between a vacuum state or a blowing state to achieve suction or release of a product.

The shaft structure 331 is rotatably arranged, and compared with the arrangement mode that the shaft structure 331 is driven by the linear motor, the problem that the linear motor is shut down due to overheating of the motor caused by continuous reciprocating motion can be avoided, so that the speed of driving each switching valve 332 by the shaft structure 331 is greatly increased, and the operation efficiency of the packaging machine is improved.

The switching structure is respectively disposed on the turret 320 and the spin head 310, so that there is no active motion mechanism on the spin head 310, the structure of the spin head 310 can be effectively simplified, and meanwhile, the mass of the spin head 310 can be reduced, and finally, the operation speed is increased.

Further, it is to be understood that a positioning means for placing the suction nozzle 311 in a negative pressure position or a positive pressure position is provided between the switching valve 332 and the spin head 310.

The positioning device may be a magnetic attraction object, and further, a magnetic attraction force between the magnetic attraction objects is smaller than a driving force of the shaft structure 331 to the switching valve 332, so that the switching valve 332 and the rotating head 310 are in a magnetic attraction state, and the shaft structure 331 can push the switching valve 332 to rotate to change a position state thereof.

The positioning device may also be a spring positioning ball, the spring positioning ball is disposed on the sidewall of the valve cavity 312, and meanwhile, the switching valve 332 is respectively provided with a concave 3323 corresponding to the negative pressure position and the positive pressure position, and when the switching valve 332 rotates to the position where the concave 3323 is opposite to the spring positioning ball, the spring positioning ball is matched with the concave 3323, so as to position the switching valve 332.

By providing the positioning device, after the suction nozzle 311 sucks the product, in order to stably maintain the suction nozzle 311 in the vacuum sucking state, the positioning device is respectively disposed corresponding to the negative pressure position and the positive pressure position of the switching valve 332, so that the switching valve 332 can be fixed at the negative pressure position or the positive pressure position, and the suction nozzle 311 can be stably maintained in the vacuum sucking state.

Referring to fig. 3, 4 and 14, in some embodiments of the present application, a rotation shaft of the rotary head 310 is hollow and communicates with an external negative pressure generating device, and a negative pressure channel is provided on the rotary head 310 in a radial direction thereof; the switching valve 332 is provided with a first passage 332a and a second passage 332b, the first passage 332a being capable of communicating the negative pressure passage with the suction nozzle 311, and the second passage 332b being capable of communicating the external air-blowing device 600 with the suction nozzle 311.

It is understood that the valve chamber 312 communicates with two opposite sides of the rotary head 310, and therefore, when the rotary head 310 rotates along the X-axis, the valve chamber 312 rotates along the second circular arc track a.

Furthermore, an opening of one end of the second channel 332b is disposed at an end of the switching valve 332 away from the shaft structure 331, and the external air blowing device 600 is fixedly disposed on the rotating frame 320 and is disposed toward the valve cavity 312, and the external air blowing device 600 can blow air toward the valve cavity 312.

When the switching valve 332 is at the positive pressure level, one end of the second passage 332b is open to the external air blowing device 600 and is communicated with the external air blowing device 600, and the other end is open to the suction nozzle 311, so that the suction nozzle 311 can be in an air blowing state; when the switching valve 332 is in the negative pressure position, the one end opening of the second passage 332b is misaligned with the external blow-up device, and the first passage 332a communicates the negative pressure passage and the suction nozzle 311, thereby enabling the suction nozzle 311 to be in a vacuum negative pressure state.

Referring to fig. 5 to 7, in some embodiments of the present application, the switching valve 332 is arranged in a rolling manner, a driving block 3311 is arranged on the shaft structure 331, and a driven block 3321 is arranged on the switching valve 332, and the driving block 3311 can abut against different end faces of the driven block 3321, so as to drive the switching valve 332 to rotate.

It will be appreciated that the shaft structure 331 rotates about a first axis, as does the switching valve 332, which is understood to be parallel to the X axis.

It should be understood that the driving block 3311 has at least two end surfaces to be capable of abutting different end surfaces on the driven block 3321, respectively. Further, the two end surfaces of the driving block 3311, which abut against the driven block 3321, may be formed on the same block or may be formed on two separate blocks.

In this embodiment, in particular, the master block 3311 has a first position, a second position and a third position, and the slave block 3321 has a negative pressure position and a positive pressure position, and in some embodiments, the angle between the negative pressure position and the positive pressure position may be 90 °. In the initial state, the active block 3311 is at the first position, and at this time, the switching valve 332 can rotate along the second arc trajectory a following the spin head 310 without colliding with the active block 3311; when the shaft structure 331 rotates the driving block 3311 from the first position to the second position by the driving of the rotating device, the driving block 3311 abuts against the driven block 3321 and pushes the driven block 3321 to switch from the positive pressure position to the negative pressure position; when the shaft structure 331 rotates the driving block 3311 from the first position to the third position by the driving of the rotating device, the driving block 3311 abuts against the driven block 3321 and pushes the driven block 3321 to switch from the negative pressure position to the positive pressure position.

It is to be understood that the first and second passages 332a and 332b of the switching valve 332 are disposed offset from the axis of the switching valve 332.

Before material suction, the second channel 332b of the switching valve 332 faces the external blowing device 600, meanwhile, the rotary head 310 is communicated with the external negative pressure generating device, the active block 3311 is at the first position, and each switching valve 332 is at the positive pressure position. When sucking material, the driving block 3311 rotates from the first position to the second position to push the switching valve 332 to switch from the positive pressure position to the negative pressure position, because the rotary head 310 is always communicated with the negative pressure generating device, when the switching valve 332 is in the negative pressure position, the suction nozzle 311 immediately generates negative pressure to suck the product, after the suction nozzle 311 sucks the product, the switching valve 332 is kept unchanged at the negative pressure position, the rotary head 310 rotates along the first axis to rotate the next switching valve 332 to face the axial structure 331, meanwhile, the driving block 3311 is switched from the second position to the first position, and the above steps are repeated.

In the mounting work, the rotary head 310 is simultaneously communicated with the external blowing unit 600 and the negative pressure generating unit, and the active block 3311 is in the first position and the respective switching valves 332 are maintained in the negative pressure position before the mounting. When the patch is stuck, the active block 3311 rotates from the first position to the third position, so as to push the switching valve 332 to switch from the negative pressure position to the positive pressure position, because the rotary head 310 is always communicated with the blowing device, when the switching valve 332 is at the positive pressure position, the suction nozzle 311 blows air immediately, so as to stick the product onto the workpiece, after the suction nozzle 311 sticks the product onto the workpiece, the switching valve 332 keeps unchanged at the positive pressure position, the rotary head 310 rotates along the first axis, so as to rotate the next switching valve 332 to face the shaft structure 331, and at the same time, the active block 3311 switches from the third position to the first position, and repeats the above steps.

Referring to fig. 5-7, in some embodiments of the present application, the angle between the two end faces of the master block 3311 that abut the slave block 3321 is less than or equal to 180 °; the included angle between the two end surfaces of the driven block 3321 abutting against the driving block 3311 is less than or equal to 90 °.

It is understood that both end surfaces of the master block 3311 abutting the slave block 3321 are disposed parallel to the first axis, and that an axis of intersection of both end surfaces of the master block 3311 coincides with the first axis; meanwhile, both end surfaces of the driven piece 3321 abutting against the driving piece 3311 are disposed parallel to the first axis, and an axis of intersection of both end surfaces of the driven piece 3321 coincides with the first axis.

Referring to fig. 6 and 7, it should be noted that when the driving block 3311 is at the first position, the two end surfaces of the driving block 3311 abutting against the driven block 3321 are located inside the second circular arc track a, and the negative pressure position and the positive pressure position of the driven block 3321 are located outside the second circular arc track a.

Referring to fig. 6 and 7, further, an angle between both end surfaces of the driving block 3311 abutting against the driven block 3321 is less than or equal to 180 °, and an angle between both end surfaces of the driven block 3321 abutting against the driving block 3311 is less than or equal to 90 °. With this arrangement, when the driving block 3311 is located at the first position, no matter the switching valve 332 is located at the negative pressure position or the positive pressure position, the switching valve 332 rotates along the second arc track a without colliding with the driving block 3311, so that the suction nozzle 311 can be stably maintained at the negative pressure position or the positive pressure position.

Referring to fig. 8-11 and 13, in some embodiments of the present application, a helical channel is provided on the circumferential surface of the shaft structure 331, the helical channel having a first opening 331a and a second opening 331 b; the switching valve 332 is slidably disposed, and a driven device 3321 is disposed on the switching valve 332, and the driven device 3321 can enter or leave the spiral passage from the first opening 331a or the second opening 331 b; different side walls of the helical channel can abut against the driven device 3321 to push the switching valve 332 to slide.

It will be appreciated that the helical channel may be formed in a helical groove in the circumferential surface of the shaft structure 331, or alternatively, the helical channel may be formed in a helical stop in the circumferential surface of the shaft structure 331.

Take the example where the helical channel is formed on a helical stop on the circumferential surface of the shaft structure 331.

A first stopper 3312 and a second stopper 3313 are disposed on the circumferential surface of the shaft structure 331, the first stopper 3312 and the second stopper 3313 are disposed opposite to each other at a certain distance on the circumferential surface of the shaft structure 331, and a spiral passage is formed between the first stopper 3312 and the second stopper 3313.

Specifically, referring to fig. 13, the first stopper 3312 has a first inlet port 33121 at an end away from the spin head 310, a first outlet port 33122 at an end close to the spin head 310, a second inlet port 33131 at an end away from the spin head 310, and a second outlet port 33132 at an end close to the spin head 310. It should be understood that the first and second inlet ports 33121, 33131 are offset on the axis of the shaft structure 331 such that a first opening 331a is defined between the first and second inlet ports 33121, 33131; meanwhile, the first outlet port 33122 and the second outlet port 33132 are offset on the axis of the shaft structure 331 so that a second opening 331b is formed between the first outlet port 33122 and the second outlet port 33132.

In this embodiment, the shaft structure 331 is provided with at least a fourth position and a fifth position. It is to be understood that the fourth position may be a negative pressure position corresponding to the switching valve 332, and the fifth position may be a positive pressure position corresponding to the switching valve 332; alternatively, the positions of the two corresponding switching valves 332 may be reversed.

Taking the fourth position on the shaft structure 331 corresponding to the negative pressure position of the switching valve 332 and the fifth position corresponding to the positive pressure position of the switching valve 332 as an example: when the switching valve 332 is in the negative pressure position, the switching valve 332 is located in the first opening 331 a; when the switching valve 332 is in the positive pressure position, the switching valve 332 is located in the second opening 331 b.

Specifically, when the switching valve 332 is slidably disposed, the switching process of the switching valve 332 is as follows:

referring to fig. 8 and 9, when the switching valve 332 is switched from the negative pressure position to the positive pressure position, the driven device 3321 is located in the first opening 331a, and when the shaft structure 331 rotates counterclockwise, the second stopper 3313 contacts the driven device 3321 and pushes the switching valve 332 to slide away from the shaft structure 331 until the driven device 3321 leaves the second outlet end 33132 and enters the second opening 331 b;

referring to fig. 10 and 11, when the switching valve 332 is switched from the positive pressure position to the negative pressure position, the driven device 3321 is located in the second opening 331b, and the shaft structure 331 rotates clockwise, the first stopper 3312 contacts the driven device 3321 and pushes the switching valve 332 to slide in a direction close to the shaft structure 331 until the driven device 3321 leaves the first outlet port 33122 and enters the first opening 331 a.

By such an arrangement, the shaft structure 331 can realize conversion of rotation thereof into linear movement of the switching valve 332, and the shaft structure 331 can efficiently and stably drive the switching valve 332.

Referring to fig. 8 to 11 and 13, in some embodiments of the present application, the driven device 3321 is rotatably provided to the switching valve 332; the first and second openings 331a and 331b are sized to be larger than the diameter of rotation of the driven device 3321; the depth of the helical channel is less than the height of the driven device 3321.

It is understood that the driven device 3321 may be a bearing rotatably disposed on the switching valve 332, a rotating ring, or a ball, and is not limited thereto.

Meanwhile, the size of the first opening 331a and the second opening 331b is larger than the rotation diameter of the driven device 3321, and is configured such that the driven device 3321 can smoothly enter or leave the first opening 331a and/or the second opening 331b to prevent the driven device 3321 from interfering with the first stopper 3312 or the second stopper 3313 when entering the spiral passage; also, the heights of the first and second stoppers 3312 and 3313 are smaller than the height of the driven device 3321, so that the valve body of the switching valve 332 does not collide with the first or second stoppers 3312 and 3313.

Further, the angle between the first inlet end 33121 and the second inlet end 33131, as viewed axially from the axial structure 331, is greater than or equal to 90 °, and the angle between the first outlet end 33122 and the second outlet end 33132 is also greater than or equal to 90 °. When the shaft structure 331 is located at the fourth position, the second stopper 3313 is located outside the circular arc line of the second circular arc track a, so that the driven device 3321 does not collide with the second stopper 3313 when the driven device 3321 enters the first opening 331 a; similarly, when the shaft structure 331 is located at the fifth position, the first stopper 3312 is located outside the circular arc line of the second circular arc track a, so that the driven device 3321 does not collide with the first stopper 3312 when the driven device 3321 enters the second opening 331 b. By such arrangement, complete and reliable matching between the shaft structure 331 and the switching valve 332 can be effectively ensured.

When the spin head 310 rotates around the X-axis, the switching valve 332 follows the spin head 310 to rotate around the X-axis in the valve cavity 312, and at this time, the rotation track of the switching valve 332 is the second circular arc track a.

Referring to fig. 11, the initial position of the switching valve 332 on the spin head 310 is a positive pressure. Before the switching valve 332 rotates to face the shaft structure 331, the shaft structure 331 is in a fifth position; when the rotary head 310 rotates clockwise and the switching valve 332 rotates to face the shaft structure 331 along with the rotary head 310, the driven device 3321 enters the second opening 331 b; the shaft structure 331 rotates clockwise, the first stopper 3312 makes rolling contact with the driven device 3321 and pushes the driven device 3321 to slide from the second opening 331b to the first opening 331a, thereby switching the switching valve 332 from the positive pressure position to the negative pressure position; after the driven device 3321 is located in the first opening 331a, the driven device 3321 completely leaves the spiral path, at this time, the shaft structure 331 stops rotating, and the rotary head 310 continues to rotate clockwise and drives the switching valve 332 away from the shaft structure 331.

Referring to fig. 9, the initial position of the switching valve 332 on the spin head 310 is a negative pressure position. Before the switching valve 332 rotates to face the shaft structure 331, the shaft structure 331 is in the fourth position; when the rotary head 310 rotates clockwise and the switching valve 332 rotates to face the shaft structure 331 along with the rotary head 310, the driven device 3321 enters the first opening 331 a; the shaft structure 331 rotates counterclockwise, the second stopper 3313 makes rolling contact with the driven device 3321 and pushes the driven device 3321 to slide from the first opening 331a to the second opening 331b, thereby switching the switching valve 332 from the negative pressure position to the positive pressure position; after the driven device 3321 is located in the second opening 331b, the driven device 3321 completely leaves the spiral path, at this time, the shaft structure 331 stops rotating, and the rotary head 310 continues to rotate clockwise and drives the switching valve 332 away from the shaft structure 331.

The embodiments of the present application have been described in detail with reference to the drawings, but the present application is not limited to the embodiments, and various changes can be made without departing from the spirit of the present application within the knowledge of those skilled in the art.
