Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

Reference herein to "an embodiment" or "an implementation" means that a particular feature, structure, or characteristic described in connection with the embodiment or implementation can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 to 2, the present application provides a processing system 100, wherein the processing system 100 includes a first apparatus 1, a second apparatus 2 and a transition apparatus 3. The transition device 3 is at least partially disposed between the first device 1 and the second device 2 to assist in transferring the workpiece 200 between the first device 1 and the second device 2.

The first apparatus 1 may be, but is not limited to, a loading/unloading apparatus, where loading refers to placing the workpiece 200 to be processed on the loading/unloading apparatus, and unloading refers to removing the processed workpiece 200 from the loading/unloading apparatus, and thus, the loading/unloading apparatus is an apparatus for carrying the workpiece 200 to be processed and the processed workpiece 200. The second device 2 may be, but is not limited to, a machining device, which is a device for machining the workpiece 200 to be machined.

The workpiece 200 needs to be transferred between the first apparatus 1 and the second apparatus 2, and the transition apparatus 3 is similar to a bridge to transition the workpiece 200 from the first apparatus 1 to the second apparatus 2 or to transition the workpiece 200 from the second apparatus 2 to the first apparatus 1.

Referring to fig. 3 and 4, the workpiece 200 includes a plate 4 and a positioning element 5, the positioning element 5 is fixedly connected to the plate 4, and the plate 4 may be, but not limited to, a Printed Circuit Board (PCB), a mobile phone shell, and the like. During the conveying process, the plate 4 is carried on the transition device 3, and the positioning element 5 is used for positioning the plate 4 during the conveying process, so as to ensure that the movement of the plate 4 does not deviate from the set path.

The transition device 3 in the processing system 100 provided in the above embodiment will be described in detail with reference to the accompanying drawings.

Referring to fig. 5 to 8, the present application provides a transition device 3, wherein the transition device 3 is used for assisting the transfer of a workpiece 200 between a first device 1 and a second device 2, the transition device 3 comprises a first guiding assembly 31 and a driving assembly 33, and the description of the first guiding assembly 31 and the driving assembly 33 is as follows.

The first guide assembly 31 includes a first sub-assembly 311 and a second sub-assembly 312. The first sub-assembly 311 and the second sub-assembly 312 together form a first opening K1 and a second opening K2 that communicate.

The driving assembly 33 is used for driving the first guiding assembly 31 to move so as to change the size of the first opening K1 and the second opening K2. When the first opening K1 is increased by the driving module 33 (as shown in fig. 7), the second opening K2 is decreased by the driving module 33, and the first opening K1 is used to guide the positioning element 5 on the workpiece 200 to the second opening K2. When the second opening K2 is increased by the driving of the driving assembly 33 (as shown in fig. 8), the first opening K1 is decreased by the driving of the driving assembly 33, and the second opening K2 is used to guide the positioning element 5 on the workpiece 200 to the first opening K1.

In particular, the first opening K1 is adjacent to the first device 1 and the second opening K2 is adjacent to the second device 2. Alternatively, the arrangement direction of the first opening K1 and the second opening K2 coincides with the arrangement direction of the first device 1 and the second device 2. In other embodiments, the arrangement direction of the first opening K1 and the second opening K2 and the arrangement direction of the first device 1 and the second device 2 may be inclined, that is, the workpiece 200 is obliquely conveyed.

The driving assembly 33 can drive the first guiding assembly 31 to change the sizes of the first opening K1 and the second opening K2, and the change trends of the first opening K1 and the second opening K2 are opposite, that is, the second opening K2 is reduced when the first opening K1 is increased, and the second opening K2 is increased when the first opening K1 is reduced.

The enlarged first opening K1 (or the second opening K2) is in an open state, and the first opening K1 (or the second opening K2) in the open state facilitates the entering of the positioning member 5 on the workpiece 200. The reduced first opening K1 (or the second opening K2) is in a limiting state, and the first opening K1 (or the second opening K2) in the limiting state is used for limiting the position of the positioning member 5.

During the transfer of the workpiece 200 from the first apparatus 1 to the second apparatus 2, the workpiece needs to pass through the first opening K1 and the second opening K2 in sequence, and the first opening K1 is in an open state and the second opening K2 is in a contracted state. Since the first opening K1 is in the open state, the positioning element 5 on the workpiece 200 can easily enter the first opening K1 and be guided into the second opening K2 by the first opening K1, and since the second opening K2 is in the reduced state, the positioning element 5 on the workpiece 200 is limited in the narrow second opening K2, so that the moving direction of the workpiece 200 can be ensured not to be deflected by the second opening K2, and the workpiece 200 can be transferred to the designated position on the second device 2.

Similarly, the workpiece 200 needs to pass through the second opening K2 and the first opening K1 in sequence during the process of transferring from the second apparatus 2 to the first apparatus 1, and the second opening K2 is in the open state and the first opening K1 is in the contracted state during the process. Since the second opening K2 is in the open state, the positioning element 5 on the workpiece 200 can easily enter the second opening K2 and be guided into the first opening K1 by the second opening K2, and since the first opening K1 is in the reduced state, the positioning element 5 on the workpiece 200 is limited in the narrow first opening K1, so that the movement direction of the workpiece 200 can be ensured not to be deflected by the first opening K1, and the workpiece 200 can be transferred to the designated position on the first device 1.

In the related art, the processing system is not provided with the transition device, and during the process of transferring the workpiece between the first device and the second device, the workpiece is prone to be deflected, so that the workpiece cannot be smoothly transferred from the first device to the designated position of the second device, or cannot be smoothly transferred from the second device to the designated position of the first device, and further the workpiece is stuck or even damaged.

The transition device 3 provided in the present application can overcome the problems in the related art. The transition device 3 includes a first guide assembly 31 and a driving assembly 33, the first guide assembly 31 has a first opening K1 and a second opening K2 communicated with each other, and the driving assembly 33 is used for driving the first guide assembly 31 to change the size of the first opening K1 and the second opening K2. Wherein the increasing and decreasing trends of the first opening K1 and the second opening K2 are opposite, that is, when the first opening K1 is increased, the second opening K2 is decreased; when the first opening K1 is reduced, the second opening K2 is increased. It can be understood that the enlarged first opening K1 (or the second opening K2) facilitates the entering of the positioning element 5 on the workpiece 200, and guides the positioning element 5 into the reduced second opening K2 (or the first opening K1), and the reduced second opening K2 (or the first opening K1) can limit the moving direction of the workpiece 200 by the positioning element 5 without deviating, so as to regulate the transferring movement of the workpiece 200, and ensure that the workpiece 200 can be accurately and smoothly transferred between the first device 1 and the second device 2.

The number of the positioning members 5 on the workpiece 200 may be one, or may be plural (two or more). When the number of the positioning members 5 is three or more, all the positioning members 5 are arranged in a straight line.

Further, the change in the size of the first opening K1 and the second opening K2 is achieved by movement of at least one of the first sub-assembly 311 and the second sub-assembly 312. It should be noted that the present application is only exemplified by the first sub-assembly 311 and the second sub-assembly 312 moving simultaneously.

The first sub-assembly 311 and the second sub-assembly 312 are connected. The first sub-assembly 311 may transmit motion to the second sub-assembly 312, or the second sub-assembly 312 may transmit motion to the first sub-assembly 311 to collectively change the size of the first opening K1 and the second opening K2 by the first sub-assembly 311 and the second sub-assembly 312.

In other words, since the first sub-assembly 311 and the second sub-assembly 312 are connected, as long as one of them moves, the other will be brought, i.e., when the first sub-assembly 311 moves, the second sub-assembly 312 will follow the first sub-assembly 311, or, when the second sub-assembly 312 moves, the first sub-assembly 311 will follow the second sub-assembly 312. Therefore, the driving assembly 33 only needs to drive any one of the first sub-assembly 311 and the second sub-assembly 312, and two sets of driving assemblies 33 are not needed to separately drive the first sub-assembly 311 and the second sub-assembly 312, respectively, so that cost and assembly space can be saved.

Referring to fig. 9, the first sub-assembly 311 includes a first guide block 3111 and a first transmission member 3112 connected to each other. The second sub-assembly 312 includes a second guide block 3121 and a second transmission piece 3122 connected. Wherein the first guide block 3111 and the second guide block 3121 are disposed at intervals and are used to jointly constitute the first opening K1 and the second opening K2. The first transmission piece 3112 and the second transmission piece 3122 are cooperatively connected to enable the first sub-assembly 311 and the second sub-assembly 312 to rotate synchronously.

Referring to fig. 10, specifically, the first guide block 3111 and the second guide block 3121 have a substantially triangular shape. Wherein, the first guide block 3111 has a first side wall M1 and a second side wall M2 inclined relatively. The second guide block 3121 has a third side wall M3 and a fourth side wall M4 which are relatively inclined. The first side wall M1 and the third side wall M3 are oppositely arranged and are used for jointly constituting a first opening K1. The second side wall M2 and the fourth side wall M4 are oppositely disposed and are used to jointly constitute a second opening K2.

The first transmission member 3112 and the first guide block 3111 rotate synchronously. The second transmission member 3122 and the second guide block 3121 rotate in synchronization. The first transmission member 3112 and the first guide block 3111 may be connected by a first rotation shaft 3113. The second transmission piece 3122 and the second guide block 3121 may be connected by a second rotation shaft 3123. The first transmission member 3112 and the second transmission member 3122 may be gears, which are directly engaged. Optionally, the first transmission member 3112 and the second transmission member 3122 are gears with the same size parameter, that is, the modulus, the number of teeth, and the like of the two are the same.

When the first transmission piece 3112 and the second transmission piece 3122 rotate, the first guide block 3111 and the second guide block 3121 are respectively driven to rotate synchronously, and the included angle between the first side wall M1 and the third side wall M3 is correspondingly increased or decreased, that is, the first opening K1 is correspondingly increased or decreased; at the same time, the included angle between the second side wall M2 and the fourth side wall M4 is increased or decreased correspondingly, i.e., the included angle of the second opening K2 is increased or decreased correspondingly.

Optionally, when the first sidewall M1 and the third sidewall M3 are parallel (i.e., the included angle between the first sidewall M1 and the third sidewall M3 is zero), the first opening K1 is smallest, and at this time, the included angle between the second sidewall M2 and the fourth sidewall M4 is larger than zero, and the second opening K2 is largest. When the second sidewall M2 and the fourth sidewall M4 are parallel (i.e. the included angle between the second sidewall M2 and the fourth sidewall M4 is zero), the second opening K2 is the smallest, the included angle between the first sidewall M1 and the third sidewall M3 is larger than zero, and the first opening K1 is the largest.

Referring to fig. 11, the transition device 3 further includes a second guiding assembly 32, and the second guiding assembly 32 includes a third sub-assembly 321 and a fourth sub-assembly 322. The third sub-assembly 321 and the fourth sub-assembly 322 together form a third opening K3 and a fourth opening K4 which are communicated with each other. The third opening K3 faces the second opening K2, i.e., the third opening K3 is more adjacent to the second opening K2 than the fourth opening K4. The driving assembly 33 is also used for driving the second guiding assembly 32 to change the size of the third opening K3 and the fourth opening K4. Wherein the third opening K3 is increased or decreased in synchronization with the first opening K1, and the fourth opening K4 is increased or decreased in synchronization with the second opening K2.

Specifically, the first guiding assembly 31 is adjacent to the first device 1, and the second guiding assembly 32 is adjacent to the second device 2. Alternatively, the arrangement direction of the first guide unit 31 and the second guide unit 32 is the same as the arrangement direction of the first device 1 and the second device 2, and the arrangement direction of the third opening K3 and the fourth opening K4 is the same as the arrangement direction of the first device 1 and the second device 2. In other embodiments, the arrangement direction of the first guide assembly 31 and the second guide assembly 32 and the arrangement direction of the first device 1 and the second device 2 may be inclined, that is, the workpiece 200 is obliquely conveyed.

The driving assembly 33 may drive the second guiding assembly 32 such that the sizes of the third opening K3 and the fourth opening K4 are changed, and the change trends of the third opening K3 and the fourth opening K4 are opposite, that is, the fourth opening K4 is reduced when the third opening K3 is increased, and the fourth opening K4 is increased when the third opening K3 is reduced.

The enlarged third opening K3 (or the fourth opening K4) is in an open state, and the third opening K3 (or the fourth opening K4) in the open state facilitates the entering of the positioning member 5 on the workpiece 200. The reduced third opening K3 (or the fourth opening K4) is in a limiting state, and the third opening K3 (or the fourth opening K4) in the limiting state is used for limiting the position of the positioning member 5.

The third opening K3 and the first opening K1 change in synchronization, and the fourth opening K4 and the second opening K2 change in synchronization. In other words, when the first opening K1 is in the open state (or the restraining state), the third opening K3 is also in the open state (or the restraining state). When the second opening K2 is in the open state (or the restraining state), the fourth opening K4 is also in the open state (or the restraining state).

During the transfer of the workpiece 200 from the first apparatus 1 to the second apparatus 2, the first opening K1 and the third opening K3 are both in an open state. During the transfer of the workpiece 200 from the second apparatus 2 to the first apparatus 1, the fourth opening K4 and the second opening K2 are both in an open state.

The third sub-assembly 321 and the fourth sub-assembly 322 are connected, and the third sub-assembly 321 can transmit motion to the fourth sub-assembly 322, or the fourth sub-assembly 322 can transmit motion to the third sub-assembly 321, so that the third opening K3 and the fourth opening K4 can be changed in size by the third sub-assembly 321 and the fourth sub-assembly 322 together.

In other words, since the third sub-assembly 321 and the fourth sub-assembly 322 are connected, as long as one of them moves, the other one will be brought, i.e., when the third sub-assembly 321 moves, the fourth sub-assembly 322 will follow the third sub-assembly 321, or, when the fourth sub-assembly 322 moves, the third sub-assembly 321 will follow the fourth sub-assembly 322. Therefore, the driving assembly 33 only needs to drive any one of the third sub-assembly 321 and the fourth sub-assembly 322, and two sets of driving assemblies 33 are not needed to separately drive the third sub-assembly 321 and the fourth sub-assembly 322, so that the cost and the assembly space can be saved.

Referring to fig. 11, the third sub-assembly 321 includes a third guide block 3211 and a third transmission member 3212 connected to each other, the fourth sub-assembly 322 includes a fourth guide block 3221 and a fourth transmission member 3222 connected to each other, the third guide block 3211 and the fourth guide block 3221 are spaced apart from each other and are configured to form the third opening K3 and the fourth opening K4 together, and the third transmission member 3212 and the fourth transmission member 3222 are cooperatively connected to enable the third sub-assembly 321 and the fourth sub-assembly 322 to rotate synchronously.

Specifically, the third and fourth guide blocks 3211 and 3221 have a substantially triangular shape. The third guide block 3211 has a fifth side wall M5 and a sixth side wall M6, which are inclined with respect to each other. The fourth guide block 3221 has seventh and eighth sidewalls M7 and M8 which are inclined with respect to each other. The fifth side wall M5 and the seventh side wall M7 are oppositely disposed and are used to jointly form the third opening K3. The sixth side wall M6 and the eighth side wall M8 are oppositely disposed and are used to jointly form the fourth opening K4.

The third transmission member 3212 and the third guide block 3211 rotate synchronously. The fourth driving element 3222 and the fourth guiding block 3221 rotate synchronously. The third transmission member 3212 and the third guide block 3211 may be connected by a third rotating shaft 3213. Fourth driving element 3222 and fourth guide block 3221 may be connected by a fourth shaft 3223. The third transmission member 3212 and the fourth transmission member 3222 may be gears, and they are directly engaged. Optionally, the third transmission member 3212 and the fourth transmission member 3222 are gears having the same size parameter, that is, the modulus, the tooth number, and other parameters of the two are the same.

When the third transmission piece 3212 and the fourth transmission piece 3222 rotate, the third guide block 3211 and the fourth guide block 3221 are driven to rotate synchronously, and an included angle formed between the fifth side wall M5 and the seventh side wall M7 is increased or decreased correspondingly, that is, the third opening K3 is increased or decreased correspondingly; meanwhile, the included angle between the sixth side wall M6 and the eighth side wall M8 is increased or decreased correspondingly, that is, the fourth opening K4 is increased or decreased correspondingly.

Optionally, when the fifth sidewall M5 and the seventh sidewall M7 are parallel (i.e., the included angle between the fifth sidewall M5 and the seventh sidewall M7 is zero), the third opening K3 is the smallest, the included angle between the sixth sidewall M6 and the eighth sidewall M8 is greater than zero, and the fourth opening K4 is the largest. When the sixth sidewall M6 and the eighth sidewall M8 are parallel (i.e., the included angle between the sixth sidewall M6 and the eighth sidewall M8 is zero), the fourth opening K4 is the smallest, the included angle between the fifth sidewall M5 and the seventh sidewall M7 is greater than zero, and the third opening K3 is the largest.

Referring to fig. 12, the transition device 3 further includes a connecting rod 34, and the connecting rod 34 is connected to the first guide assembly 31 and the second guide assembly 32, so that the first guide assembly 31 and the second guide assembly 32 move synchronously. In other words, the link 34 may transmit the motion of the first guide assembly 31 to the second guide assembly 32, or transmit the motion of the second guide assembly 32 to the first guide assembly 31. Therefore, the driving assembly 33 only needs to drive either one of the first guide assembly 31 and the second guide assembly 32.

In one embodiment, the link 34 may be connected to the second sub-assembly 312 and the fourth sub-assembly 322, respectively, and the second sub-assembly 312 and the fourth sub-assembly 322 are linked by the link 34. Further, the connecting rod 34 may be connected to the second guide block 3121 and the fourth guide block 3221 (as shown in fig. 12), respectively, or connected to the second rotating shaft 3123 and the fourth rotating shaft 3223, respectively, or connected to the second transmission member 3122 and the fourth transmission member 3222, respectively.

In another embodiment, the connecting rod 34 may also be connected to the first sub-assembly 311 and the third sub-assembly 321, respectively, and the first sub-assembly 311 and the third sub-assembly 321 are linked by the connecting rod 34. Further, the connecting rod 34 may be respectively connected to the first guide block 3111 and the third guide block 3211, or respectively connected to the first rotating shaft 3113 and the third rotating shaft 3213, or respectively connected to the first transmission member 3112 and the third transmission member 3212.

It will be appreciated that the plate 4 of the workpiece 200 has a certain volume, and when the workpiece 200 is at least partially moved to the transition device 3, the plate 4 can be carried by the roller 354, so that the movement of the workpiece 200 can be made smooth and travel along the extension of the guide channel D, while the roller 354 can be rotated, so that the wear of the workpiece 200 during its movement can be reduced.

Referring to fig. 15, the transition device 3 further includes a blocking assembly 36, and the blocking assembly 36 includes a driving member 362 and a blocking member 361 connected to each other. The driving member 362 is used for driving the blocking member 361 to move, so that the blocking member 361 is located in the extending direction of the first opening K1 pointing to the second opening K2.

Specifically, the blocking member 361 has a blocking state (see fig. 16 and 17) and a releasing state (see fig. 18), and the driving member 362 can drive the blocking member 361 to switch between the blocking state and the releasing state. When the blocking member 361 is in the blocking state, the blocking member 361 is located in the extending direction of the first opening K1 pointing to the second opening K2, that is, the blocking member 361 is located on the moving path of the positioning member 5, and the workpiece 200 stops moving after the positioning member 5 abuts against the blocking member 361. The workpiece 200 stays at the predetermined position, and the workpiece 200 stays at the predetermined position, so that the second device 2 can pick up the workpiece 200. Thus, the stop assembly 36 functions to position the workpiece 200 in a predetermined position. When the blocking member 361 is in the release state, the blocking member 361 is not in the extending direction of the first opening K1 pointing to the second opening K2, so that the movement of the positioning member 5 is not blocked.

Optionally, the moving direction of the blocking member 361 is parallel to the direction in which the first top plate 3511 and the second top plate 3521 point to the bottom plate 3533. The orthographic projection of the blocking member 361 on the first top plate 3511 and the second top plate 3521 falls at least partially within a range between the first top plate 3511 and the second top plate 3521, in other words, the blocking member 361 is right opposite to the guide passage D. When the positioning piece 5 is positioned in the guide channel D, the height of the positioning piece 5 from the bottom plate portion 3533 is a first height; the height of the blocking member 361 protruding from the bottom plate portion 3533 is a second height. When the blocking member 361 is in the blocking state, the second height is greater than or equal to the first height, and the positioning member 5 is blocked; when the blocking member 361 is in the release state, the second height is smaller than the first height, and the positioning member 5 is not blocked.

Referring to fig. 16, optionally, the blocking member 361 is further provided with a limiting groove C1, the limiting groove C1 is disposed on a side of the blocking member 361 close to the first guide assembly 31, and the limiting groove C1 is used for receiving at least part of the positioning member 5 on the workpiece 200. Since the width of the guide passage D is larger than that of the positioning member 5, the stop positions of the positioning member 5 on different workpieces 200 are different. After the limiting groove C1 is provided, the positioning members 5 on different workpieces 200 can be moved into the limiting groove C1, so that the stopping precision of the workpieces 200 can be improved, and the precision of the second device 2 for picking up the workpieces 200 can be higher.
