Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It is also to be noted that, for the convenience of description, only a part of the structure related to the present application, not the whole structure, is shown in the drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making an invasive task, are within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a workpiece 1.

The workpiece 1 (for example, VR glasses) is substantially annular, and its inner surface 101 is a surface to be detected and a positioning reference, and if the workpiece is positioned by the inner surface 101, the inner surface 101 is blocked, which is not convenient for subsequent detection.

The carrier in the following is able to position the workpiece 1 by the inner side surface 101 without also affecting the detection of the inner side surface 101. The workpiece 1 shown in fig. 1 is only an example, and the carrier can also be applied to other workpieces of similar structures.

Referring to fig. 2 to 5, fig. 2 to 4 are a front view, a left side view and a top view of an embodiment of the carrier of the present application, respectively, and fig. 5 is a front view of the carrier shown in fig. 2, omitting the carrier mounting body 13 to show the internal structure thereof.

The carrier includes a base 10, a moving member 20, a driving assembly 30, a positioning member 40 and a pressing member 50.

The susceptor 10 has a first supporting surface 142 a. The first carrying surface 142a is used for carrying the workpiece 1. Specifically, the base 10 includes a first mounting plate 11, a second mounting plate 12, a carrier mounting body 13, a carrier mounting seat 14, and a mounting seat 15. The second mounting plate 12 can be fixed to a moving end of a robot (not shown) so that the robot can move the carrier. The first mounting plate 11 is fixedly arranged on the top surface of the second mounting plate 12. The carrier mounting body 13 is fixedly arranged on the top surface of the first mounting plate 11. The carrier mounting seat 14 is fixedly arranged on the top surface of the carrier mounting main body 13. The number of the mounting seats 15 is plural (2 in the figure), and the plural mounting seats 15 are fixedly arranged on two sides of the carrier mounting main body 13.

Referring to fig. 6 to 8, fig. 6 to 8 are a front view, a left view and a top view of the carrier mounting seat 14 of the carrier shown in fig. 2, respectively.

The carrier mount 14 includes a carrier mount body 141 and a plurality of bumps 142 (four in the figure). The carrier mounting base body 141 is fixedly arranged on the top surface of the carrier mounting body 13. A through hole 143 is formed in a central region of the carrier mount body 141. The through hole 143 is used for the passage of the positioning member 40. The plurality of bumps 142 are protruded from the top surface of the carrier mounting base body 141 and are disposed around the through holes 143 at intervals. The top surface of each bump 142 forms a first supporting surface 142 a. When each of the bumps 142 supports the workpiece, the contact area with the bottom surface of the workpiece 1 is relatively small, and the shielding of the bottom surface of the workpiece 1 is reduced.

The moving member 20 is movably disposed on the base 10 and can move relative to the base 10 along a first direction D1 or a second direction D2 opposite to the first direction D1. Specifically, the base 10 includes a linear bearing 16, and the linear bearing 16 is disposed on the first mounting plate 11. Mover 20 includes a moving body 21. The moving body 21 includes a lifting/lowering mounting plate 211 and a cylindrical shaft 212 fixed to the lifting/lowering mounting plate 211. The cylindrical shaft 212 is slidably engaged with the linear bearing 16 in the first direction D1. In the vehicle using state, the first direction D1 is vertically upward, and the second direction D2 is vertically downward.

Drive assembly 30 is configured to drive moving member 20 in a first direction D1 or a second direction D2.

The positioning member 40 is disposed on the moving member 20. Specifically, the positioning member 40 is disposed on the elevating mounting plate 211. The positioning element 40 is used for protruding the positioning element 40 on the first bearing surface 142a to position the workpiece 1 after the moving element 20 moves to the first position along the first direction D1, and for separating the positioning element 40 from the first bearing surface 142a to enable the first bearing surface 142a to bear the workpiece 1 after the moving element 20 moves to the second position along the second direction D2. In the using state of the carrier, when the moving member 20 is located at the first position, the positioning element 40 is protruded above the first supporting surface 142a, and when the moving member 20 is located at the second position, the positioning element 40 is located below the first supporting surface 142 a.

Referring to fig. 9 to 11, fig. 9 to 11 are a front view, a top view and a bottom view of positioning element 40 in the carrier shown in fig. 2, respectively.

The positioning member 40 has a positioning surface 41, and the positioning surface 41 extends along the first direction D1 and is shaped and sized to match the inner side surface 101 of the workpiece 1. After the workpiece 1 is fitted on the positioning surface 41, the degree of freedom in the plane perpendicular to the first direction D1 is restricted, thereby being positioned. In a state where the first bearing surface 142a bears the workpiece 1, the positioning member 40 can be separated from the workpiece 1 while moving in the second direction D2.

The pressing member 50 is movably disposed on the base 10 and has a pressing portion 521 disposed opposite to the first bearing surface 142 a. The pressing part 50 is linked with the moving part 20, so that when the moving part 20 moves along the second direction D2, the pressing part 521 approaches the first bearing surface 142a, and the workpiece 1 is pressed against the first bearing surface 142 a. The pressing element 50 fixes the positioned workpiece 1 on the carrier, so as to prevent the workpiece 1 from displacing during the moving process.

The driving assembly 30 drives the moving member 20 to move to the first position along the first direction D1, the positioning member 40 is protruded on the first carrying surface 142a, and the positioning member 40 can position the workpiece 1 with the inner side surface 101 of the workpiece 1 as a positioning reference, so that the position of the workpiece 1 on the carrier is accurate. After the positioning is completed, the driving assembly 30 drives the moving member 20 to move to the second position along the second direction D2, in which the workpiece 1 is separated from the positioning member 40 and the workpiece 1 is supported by the first supporting surface 142 a. The inner side surface 101 of the workpiece 1 is not obstructed and thus does not affect the inspection of the workpiece 1. Meanwhile, the pressing part 50 is linked with the moving part 20, so that the pressing part 521 approaches the first bearing surface 142a during the moving of the moving part 20 along the second direction D2, and further presses the workpiece 1 against the first bearing surface 142 a. Only one driving assembly 30 is arranged, so that the positioning of the workpiece 1 and the fixing of the workpiece 1 are realized, the number of the driving assemblies 30 is reduced, and the cost is reduced.

Further, the pressing part 50 is linked with the moving part 20, so that the pressing part 521 is away from the first bearing surface 142a during the moving part 20 moving along the first direction D1. At the first inspection, the driving assembly 30 drives the moving member 20 to move along the first direction D1 to position the workpiece 1 to be loaded, and this action simultaneously moves the pressing member 50 away from the first loading surface 142a to load the workpiece 1 onto the carrier. In the continuous inspection process, after the previous workpiece 1 is inspected, the driving assembly 30 drives the moving member 20 to move along the first direction D1 to position the next workpiece 1, and this action simultaneously enables the pressing member 50 to release the previous workpiece 1. Therefore, the carrier can continuously unload the previous workpiece 1 and load the next workpiece 1, and the detection efficiency is improved.

The linkage structure of the pressing member 50 and the moving member 20 is as follows:

referring to fig. 12 to 16, fig. 12 is a schematic view showing a linkage structure of the pressing member 50 and the moving member 20, fig. 13 is a sectional view taken along line B-B in fig. 12, fig. 14 is a plan view of fig. 12, and fig. 15 and 16 are a front view and a left view of the rotary guide shaft 51 in fig. 12, respectively.

The pressing member 50 includes a rotation guide shaft 51 and a pressing lever 52. The rotary guide shaft 51 is inserted into the mount 15 of the base 10 and is capable of reciprocating along its axis with respect to the mount 15. The axis of the rotary guide shaft 51 is parallel to the first direction D1. The pressing rod 52 is fixedly arranged at the top end of the rotary guide shaft 51 and is in an L shape. The end of the pressing rod 52 forms the pressing part 521.

The carrier further comprises a first resilient member 80. Specifically, the number of the first elastic members 80 is equal to the number of the pressing members 50, and corresponds to one another. The first elastic member 80 may be a spring.

Opposite ends of the first elastic member 80 respectively abut against the base 10 and the abutting member 50 for applying a first elastic force to the abutting member 50. Specifically, in the drawings, the first elastic element 80 is sleeved outside the rotary guiding shaft 51 of the corresponding pressing element 50, and the top end thereof is used for abutting against the mounting seat 15, and the bottom end thereof is used for abutting against the pressing element 50. In this embodiment, the first elastic member 80 is always in compression. In other embodiments, the opposite ends of the first elastic element 80 can be connected to the base 10 and the pressing element 50 respectively and are always in a stretched state.

Wherein, the moving member 20 is used for pushing against the pressing member 50 and compressing the first elastic member 80 during the moving process along the first direction D1. Specifically, the rotary guide shaft 51 is located on the moving path of the moving member 20, directly above the abutting portion 22 (see below) in the moving member 20. When the moving member 20 moves along the first direction D1, it can push against the rotating guide shaft 51 to drive the rotating guide shaft 51 to move along the first direction D1, and during the movement, the rotating guide shaft 51 presses the first elastic member 80, so that the first elastic member 80 is in a compressed state. In other embodiments, if first elastic element 80 is always in a stretched state, moving element 20 pushes against pressing element 50 during moving along first direction D1, and stretches first elastic element 80.

The first elastic force is used for driving the pressing element 50 to reset during the moving of the moving element 20 along the second direction D2.

In the linkage structure, the pressing member 50 can elastically press against the workpiece 1 on the first bearing surface 142a under the action of the first elastic member 80, so as to prevent the workpiece 1 from being damaged.

When the pressing portion 521 just abuts against the workpiece 1, at least a portion of the positioning element 40 protrudes from the first bearing surface 142 a. Specifically, at least a portion of the positioning member 40 may be a top end of the positioning member 40. During the movement of the positioning member 40 in the second direction D2, the pressing portion 521 abuts against the workpiece 1 before the top surface of the positioning member 40 is lower than the first bearing surface 142 a. Before the pressing part 521 butts against the workpiece 1, the workpiece 1 is always positioned by the positioning part 40, so that the pressing part 521 is prevented from driving the workpiece 1 to move when contacting the workpiece 1, and the position precision of the workpiece 1 is ensured.

If the pressing portion 521 is always located right above the workpiece 1, it is inconvenient to take and place the workpiece 1.

The carrier includes a first guide portion 19 and a second guide portion 511. The first guide portion 19 is provided at one of the base 10 (mount 15) and the pressing member 50. The second guide portion 511 is provided to the other of the base 10 and the pressing member 50. In the drawing, the first guide portion 19 is provided in the base 10, and the second guide portion 511 is provided in the pressing member 50. The positions of the first guide portion 19 and the second guide portion 511 may be interchanged, that is, the first guide portion 19 is disposed on the pressing member 50, and the second guide portion 511 is disposed on the susceptor 10.

The second guide portion 511 extends spirally around the reference axis L1 for cooperating with the first guide portion 19 to enable the pressing member 50 to rotate around the reference axis L1 during the movement along the reference axis L1, so that the pressing portion 521 can be selectively located or withdrawn directly above the workpiece 1. The specific fit mode can be a sliding fit or a rolling fit. The reference axis L1 is parallel to the first direction D1. In the present embodiment, the reference axis L1 is the axis of the rotary guide shaft 51.

During the movement of the pressing part 50 in the second direction D2, the pressing part 50 rotates around the reference axis L1 in the third direction D3, so that the pressing part 521 rotates from the non-directly-above area of the workpiece 1 to the directly-above area of the workpiece 1, and the pressing part 521 rotates while descending, i.e. spirally descending; during the movement of the pressing member 50 in the first direction D1, the pressing member 50 rotates around the reference axis L1 in the fourth direction D4 opposite to the third direction D3, so that the pressing portion 521 rotates from a region directly above the workpiece 1 to a region not directly above the workpiece 1, and the pressing portion 521 rotates while rising, i.e., spirally rises. Therefore, the workpiece 1 is more convenient to take and place.

Further, the carrier further comprises a third guiding portion 512, the third guiding portion 512 being connected to an extended end of the second guiding portion 511, extending along the reference axis L1, for cooperating with the first guiding portion 19. The specific matching mode can be sliding fit or rolling fit.

During the movement of the pressing member 50 in the second direction D2, in the previous movement stroke, the pressing member 50 rotates around the reference axis L1 in the third direction D3, so that the pressing portion 521 rotates from the non-directly-above area of the workpiece 1 to the directly-above area of the workpiece 1, the pressing portion 521 rotates while descending, i.e., spirally descends, and in the next movement stroke, the pressing member 50 only moves (does not rotate) in the second direction D2, so that the pressing portion 521 presses on the workpiece 1; during the movement of the pressing member 50 in the first direction D1, in the former stroke, the pressing member 50 only moves (does not rotate) in the first direction D1, so that the pressing portion 521 is separated from the workpiece 1, and in the latter stroke, the pressing member 50 rotates around the reference axis L1 in the fourth direction D4, so that the pressing portion 521 rotates from the region directly above the workpiece 1 to the region not directly above the workpiece 1, and the pressing portion 521 rotates while rising, i.e., spirally rising. Therefore, the workpiece 1 positioned on the first bearing surface 142a can be prevented from being driven to move in the rotation process of the pressing part 521.

Specifically, the first guiding portion 19 may be a convex pillar, the second guiding portion 511 and the third guiding portion 512 may be grooves, and the convex pillar is inserted into the grooves and can slide along the extending path of the grooves.

In order to avoid interference when two adjacent pressing members 50 rotate, the spiral directions of the second guiding portions 511 on two adjacent pressing members 50 may be set to be opposite, so that the pressing portions 521 on two adjacent pressing members 50 may rotate in opposite directions to avoid mutual interference.

Ram 20 also includes an abutment 22. The pushing part 22 is detachably connected to the moving body 21, and is adjustable in position in the first direction D1 and/or the second direction D2. Specifically, the moving body 21 further includes a connecting plate 213, the connecting plate 213 is fixedly connected to the lifting mounting plate 211, the abutting portion 22 is screwed onto the connecting plate 213 in the moving body 21, an axis of the connecting screw of the abutting portion 22 is aligned with the second direction D2, and the abutting portion 22 can be moved along an axial direction thereof by rotating the abutting portion 22. The urging portion 22 may be a bolt. The positioning element 40 is disposed on the moving body 21, and the pushing portion 22 is used for pushing the pushing element 50. Thus, by adjusting the position of the abutting portion 22, the limit position at which the abutting piece 50 moves in the first direction D1 can be adjusted.

Referring to fig. 5, the driving assembly 30 includes a driving cylinder 31 and a second elastic member 32. The driving end of driving cylinder 31 is used for pushing moving member 20 (lifting mounting plate 211) to drive moving member 20 to move along first direction D1. The drive cylinder 31 may be an air cylinder. The cylinder body of the cylinder is arranged on the first mounting plate 11 in the base 10, and the piston rod of the cylinder is used for pushing against the moving member 20. The piston rod is separable from moveable member 20. Opposite ends of second elastic element 32 are respectively connected to/abutted against base 10 and moving element 20, for applying a second elastic force to moving element 20 during the moving stroke of moving element 20, so as to drive moving element 20 to move along second direction D2. Specifically, the base 10 includes a connection block 17, and the connection block 17 is fixedly disposed on the carrier mounting body 13. Moving body 21 of mover 20 further includes a guide rod 214. The guide rod 214 is fixedly disposed on the lifting mounting plate 211 and slidably engaged with the connecting block 17 along the first direction D1. The second elastic element 32 is sleeved outside the guide rod 214, a top end of the second elastic element 32 is used for abutting against the connecting block 17, and a bottom end of the second elastic element 32 is used for abutting against the moving body 21. The second elastic member 32 may be a spring.

Referring to fig. 2, 9 and 10, the positioning member 40 has a second bearing surface 42, and the second bearing surface 42 is used for bearing the workpiece 1. Specifically, the second bearing surface 42 is disposed around the positioning member 40 and perpendicular to the positioning surface 41. The side of the positioning member 40 is further provided with notches 43, and the notches 43 correspond to the protrusions 142 in equal number one to one. The notch 43 extends along the first direction D1 and penetrates the second bearing surface 42 for receiving the protrusion 142. When the moving member 20 is located at the first position, the second supporting surface 42 is higher than the first supporting surface 142a, and when the moving member 20 is located at the second position, the second supporting surface 42 is lower than the first supporting surface 142 a.

After moving member 20 moves to the first position along the first direction D1, workpiece 1 is sleeved on positioning element 40, and at this time, workpiece 1 is supported by second carrying surface 42. When the moving member 20 moves along the second direction D2, the workpiece 1 descends along with the descending of the second carrying surface 42, when the second carrying surface 42 is lower than the first carrying surface 142a, the first carrying surface 142a supports the workpiece 1, the positioning member 40 starts to separate from the workpiece 1, and when the moving member 20 moves to the second position, the positioning member 40 completely separates from the workpiece 1.

By arranging the second bearing surface 42, the workpiece 1 can be taken and placed at a position higher than the first bearing surface 142a, so that the workpiece 1 is prevented from being interfered by other parts in the carrier when the workpiece 1 is taken and placed.

Referring to fig. 17, fig. 17 is a sectional view taken along line a-a of fig. 4.

In order to improve the compatibility of the carrier, namely, the workpieces 1 with various specifications can be clamped, the positioning element 40 and the moving element 20 are detachably and fixedly connected through magnetic attraction.

Specifically, two positioning pins 44 (see fig. 11) are fixedly disposed on the bottom surface of the positioning member 40, positioning holes (not visible) matched with the positioning pins 44 are disposed on the lifting mounting plate 211, and the positioning member 40 is positioned on the lifting mounting plate 211 by the two positioning pins 44. The permanent magnet 215 is fixedly arranged on the top surface of the lifting mounting plate 211, the metal piece 70 is fixedly arranged on the bottom surface of the positioning piece 40, the permanent magnet 215 is arranged opposite to the metal piece 70, and the metal piece 70 can be adsorbed by the permanent magnet 215, so that the positioning piece 40 is fixedly arranged on the lifting mounting plate 211. In the case where the positioning member 40 itself can be attracted by the permanent magnet 215, the metal member 70 may not be provided. In addition, the positions of the metal piece 70 and the permanent magnet 215 can be reversed.

When the positioning member 40 needs to be replaced, the positioning member 40 can be quickly detached from the elevating mounting plate 211 by means of a manual force, and a new positioning member 40 can be installed.
