Example one

Referring to fig. 1 to 6, an embodiment of the present application provides a feeding device, for example, the feeding device can be used for continuously and uninterruptedly feeding a watch back cover, 3C small products (hereinafter referred to as a workpiece) such as glass and electronic components; the feeding device comprises a sucker 10, a rotating part 20, an air guide part 30 and a driving assembly 50; this will be explained in detail below.

Referring to fig. 1, 2, 3 and 6, the chuck 10 is detachably fixed on the rotating member 20, such as by clamping, locking, magnetic attraction, and is mainly used as a carrier or fixture for placing a workpiece. A plurality of suction structures 11, such as two, three, four or other larger numbers, are arranged on the suction cup member 10; in the present embodiment, the suction structure 11 is a dummy structure adapted to the contour of the workpiece, specifically, the suction structure 11 has a structure space for accommodating the workpiece, and parameters such as contour form and dimension of the structure space are the same as or substantially the same as the workpiece.

Firstly, the adsorption structure 11 can provide a placing space with a structure adapted to the workpiece, so as to accommodate and place the workpiece, thereby enabling the chuck piece 10 to simultaneously bear or place a plurality of workpieces, and facilitating the one-time transfer of the workpieces. Secondly, under the condition that the suction disc piece 10 is communicated with a vacuum source (such as a negative pressure device or system like a vacuum pump), the adsorption structure 11 can be used for generating a negative pressure adsorption effect on the suction disc piece 10 to adsorb and fix the workpiece so as to realize the loading, temporary storage, transfer and the like of the workpiece and avoid the phenomena of position deviation, even falling off and the like of the workpiece in the transfer process; on the contrary, the suction structure 11 can release the workpiece accommodated therein by closing the connection between the chuck 10 and the vacuum source, so as to perform blanking process on the workpiece. Thirdly, by utilizing the characteristic of the detachable assembly of the sucker 10, the sucker 10 with the adaptive adsorption structure 11 can be conveniently and quickly replaced according to different workpieces, so that the feeding device can be suitable for feeding and temporary storage of different products, and favorable conditions are created for improving the use efficiency of the feeding device and even related process equipment.

In other embodiments, the suction cup member 10 may be fixed to the rotating member 20 in a non-detachable manner depending on the application scenario of the feeding device; based on the difference of the type and size of the workpiece, the suction structure 11 may also adopt other structural forms, such as a structural structure similar to a suction nozzle or a suction cup, so as to omit the containing function thereof, thereby performing a single suction fixing function. Of course, in other embodiments, the suction cup 10 may be regarded as a functional fixture used with a feeding device, and the suction cup 10 is assembled to the feeding device when the feeding device is applied.

Referring to fig. 1 to 6, the rotating member 20 is coupled to a power end of the driving assembly 50, so that the rotating member 20 can drive the sucker 10 to rotate or stop at a predetermined specific position under the driving of the driving assembly 50, thereby providing support for loading, temporary storage, transferring, and unloading of the workpiece by adjusting the position of the sucker 10. The rotary member 20 has two air guide ports 20a, the two air guide ports 20a being provided on the rotary member 20 in such a manner as to be evenly arranged around the rotation axis L1 of the rotary member 20; suitably, the number of the suction cup members 10 is two, two suction cup members 10 are arranged on the rotating member 20 in a manner of being uniformly arranged around the rotation axis L1 of the rotating member 20, and the two suction cup members 10 are in one-to-one correspondence with the two air guide ports 20a (it can be understood that the two air guide ports 20a and the two suction cup members 10 are both arranged symmetrically with respect to the rotation axis L1 of the rotating member 20), for example, through an independently configured gas pipeline or a structural channel arranged in the rotating member 20, the suction cup members 10 are arranged in correspondence with the corresponding air guide ports 20a, so that the air path ports of the suction cup members 10 are arranged on the rotating member 20 by extending through the air guide ports 20 a.

Referring to fig. 3 and 5, the air guide member 30 is mainly used for establishing an air path communication or closing relationship between the suction cup member 10 and the vacuum source by cooperating with the rotating member 20 (specifically, the air guide opening 20 a), so as to provide a support for starting or closing the negative pressure suction function of the suction cup member 10 (specifically, the suction structure 11). The air guide member 30 is connected with the rotating member 20 in a relatively rotatable manner in a structural fit manner; for example, they are relatively rotatably fitted in a coaxially opposing manner along the rotation axis L1 of the rotary member 20; for another example, the two are engaged with each other in a manner of being coaxially fitted along the rotation axis L1 of the rotary member 20; the air guide member 30 is provided with an air guide groove 30a, the air guide groove 30a adopts an arc groove structure arranged along the rotation track of the air guide port 20a (it should be noted that the arc groove refers to a groove body structure formed between any two points on the circumference where the arc groove is located, and the two points can be understood as the head end and the tail end of the arc groove), and is mainly used for connecting a vacuum source; based on the different matching manner between the air guide 30 and the rotating member 20, the air guide groove 30a and the air guide opening 20a may be disposed coaxially and oppositely along the extending direction of the rotation axis L1 of the rotating member 20, or may be disposed concentrically and oppositely around the rotation axis L1 of the rotating member 20.

Thus, in the process that the air guide opening 20a rotates along with the rotating member 20 relative to the air guide member 30 (specifically, the air guide groove 30 a), when the air guide opening 20a and the air guide groove 30a are overlapped, the two will be communicated or conducted, so that a relatively complete vacuum channel or vacuum air path is formed between the corresponding suction cup member 10 and the vacuum source, so that the adsorption structure 11 of the suction cup member 10 generates a negative pressure adsorption function; on the contrary, when the air guide opening 20a rotates to the position between the head and the tail of the air guide groove 30a, the two air guide openings are separated or isolated by dislocation, so as to close the vacuum air path between the corresponding suction cup member 10 and the vacuum source, thereby removing or releasing the negative pressure adsorption function of the adsorption structure 11.

In this embodiment, the angle (also understood as radian) corresponding to the arc length of the air guide groove 30a is set to be less than 180 °, such as 178 ° or the like; therefore, by means of the arrangement relationship of the two air guide ports 20a and the corresponding suction cup pieces 10 on the rotating piece 20, when the rotating piece 20 rotates relative to the air guide piece 30, one of the two air guide ports 20a can be always kept in conduction with the air guide groove 30a, and the other air guide port can be always kept in dislocation isolation with the air guide groove 30a, so that the two air guide ports 20a (or the two suction cup pieces 10) can be alternatively switched to be in conduction or communication with the air guide groove 30a, and conditions are created for continuous and uninterrupted operation of workpiece feeding and blanking.

For example, referring to fig. 8, a feeding station a and a discharging station B can be defined along the rotation track of the sucking disc member 10; wherein, the loading station a can be understood as a starting position (such as a head position of the air guide slot 30 a) at which the air guide opening 20a of the suction cup member 10 is just communicated with the air guide slot 30a when the suction cup member 10 is at a certain position, and the unloading station B can be understood as a starting position (such as a tail position of the air guide slot 30 a) at which the air guide opening 20a of the suction cup member 10 is just isolated from the air guide slot 30a when the suction cup member 10 is at another position; correspondingly, workpiece grabbing mechanisms such as manipulators and the like can be arranged at the feeding station A and the discharging station B, or the workpiece grabbing mechanisms can be controllably moved to the feeding station A and the discharging station B; meanwhile, for the sake of distinction and description, referring to fig. 7 to 9, two suction cup members 10 are defined as a first suction cup member 10a and a second suction cup member 10b, respectively, and the air guide port 20a communicating with the first suction cup member 10a is designated as 20a-1 and the air guide port 20a communicating with the second suction cup member 10b is designated as 20a-2.

Referring to fig. 7 and 8, when the rotating member 20 is driven by the driving assembly 50 to rotate, so that the first chuck member 10a is rotated to stay at the feeding station a, the first chuck member 10a is communicated with the air guide slot 30a through the corresponding air guide opening 20a-1, so that the suction structure 11 of the first chuck member 10a generates a negative pressure suction function (at this time, the state of the first chuck member 10a may be defined as a first state); meanwhile, the second sucking disc 10B just moves to stay at the blanking station B, and the negative pressure adsorption function of the adsorption structure 11 is released (at this time, the state of the second sucking disc 10B can be defined as a second state); therefore, the workpieces can be placed on the adsorption structure 11 of the first chuck piece 10a one by the workpiece grabbing mechanism, and the workpieces contained in the workpieces are adsorbed and fixed by the adsorption structure 11, so that the loading processing of the workpieces on the first chuck piece 10a is realized; meanwhile, the workpiece accommodated in the suction structure 11 of the second chuck 10b is taken out by the workpiece gripping device, and the blanking process of the workpiece on the second chuck 10b is realized. Subsequently, referring to fig. 8 and 9, the driving assembly 50 drives the rotating member 20 to rotate (e.g. rotate counterclockwise from the head end position to the tail end position along the air guide slot 30 a), so that the second chuck member 10b moves to stay at the loading station and switches to the first state (while the second chuck member 10a just stays at the unloading station and switches to the second state), and the corresponding loading and unloading are continued. The continuous and uninterrupted feeding of the workpieces can be realized by the circulation.

In other embodiments, the specific curvature of the air guide groove 30a can be selected and configured according to the size of the air guide opening 20a, the rotation stroke of the suction cup 10, the loading and unloading position of the workpiece, the driving assembly 50, and the like; for example, when the arc degree of the air guide groove 30a is set to be greater than 180 °, the rotary member 20 is rotated in a progressive manner by configuring the control logic of the driving assembly 50, and when the first chuck member 10a stays at the loading station a, the second chuck member 10B stays at a position between the loading station a and the unloading station B and is communicated with the vacuum source, at this time, the workpiece adsorbed and fixed on the second chuck member 10B can be temporarily stored and processed by other processes, such as detection; when the first chuck piece 10a is fully loaded with workpieces, the driving assembly 50 is controlled to drive the rotating piece 20 to rotate, so that the second chuck piece 10B stays at the position of the blanking station B and keeps isolation from a vacuum source, and at the moment, the workpieces on the second chuck piece 10B can be subjected to blanking treatment, and because the first chuck piece 10a is positioned between the feeding station a and the blanking station B, the workpieces adsorbed and fixed by the first chuck piece can be temporarily stored and subjected to other processes; reciprocating like this, not only can realize the continuous feed to the work piece, still be convenient for carry out temporary storage and other technology to the work piece and handle.

In summary, on one hand, the air guide groove 30a is matched with the air guide opening 20a to conduct or close the vacuum source and the suction cup 10, so as to form a time sequence logic for controlling the on-off of the vacuum air path by a mechanical structure, and the on-off control of the negative pressure adsorption function of the suction cup 10 can be realized without separately configuring matching devices such as a vacuum solenoid valve and the like, so that the structure of the feeding device can be simplified, and the configuration and use cost of the feeding device can be reduced; on the other hand, the two sucking disc pieces 10 are switched between the first state and the second state under the driving of the rotating piece 20 by the radian configuration of the air guide groove 30a and the selective arrangement of the air guide ports 20a and the number and positions of the sucking disc pieces 10 corresponding to the air guide ports; for example, when one suction disc member 10 is loaded, the negative pressure adsorption function of the other suction disc member 10 is just released, so that the workpiece on the suction disc member 10 is subjected to blanking treatment, thereby realizing continuous and uninterrupted feeding, improving the feeding efficiency and enhancing the automation degree of the feeding device.

In one embodiment, referring to fig. 1, 2, 3 and 5, the rotating member 20 includes a bearing seat 21 and an engaging shaft 22; wherein, the carrying seat 21 is coupled with the power end of the driving assembly 50, the overall profile of the carrying seat 21 is substantially in the shape of a strip plate, a through hole structure (not shown in the figure) is arranged at the geometric center of the carrying seat 21 in a penetrating manner, and the two sucker members 10 are arranged at the two ends of the carrying seat 21 along the length direction of the carrying seat 21; the joint shaft 22 is fixed on the bearing seat 21 in a manner of penetrating through a through hole structure, so that the shaft axis of the joint shaft 22 can be used as the rotation axis L1 of the bearing seat 21 or the rotating member 20, and the air guide member 30 is arranged at the axial end of the joint shaft 22 along the extending direction of the rotation axis L1; an axial end face of the engaging shaft 22 facing the air guide 30 is configured as a first engaging face 22a, and the air guide port 20a is provided through the first engaging face 22 a; configuring an end surface of the air guide 30 facing the first joint surface 22a in the axial direction of the joint shaft 22 (or in the rotation axis L1) as a second joint surface 30b, the air guide groove 30a being provided on the second joint surface 30b; so that the first engagement face 22a and the second engagement face 30b face each other in the axial direction of the engagement shaft 22 (or the extending direction of the rotation axis L1), a structural fit connection relationship existing in a coaxially opposing and overlapping manner is established between the air guide 30 and the engagement shaft 22 by abutting the first engagement face 22a and the second engagement face 30b against each other at the time of specific assembly.

In another embodiment, the joint shaft 22 and the air guide 30 can also adopt a coaxial sleeved structure matching relationship; for example, a counterbore structure is provided on an end surface or a surface of the air guide 30 on a side facing the joint shaft 22, a circumferential wall of the counterbore structure is configured as a second joint surface 30b, and the air guide groove 30a is provided on the second joint surface 30b around an axial center line of the counterbore structure; suitably, the axial end of the joint shaft 22 is inserted into the counterbore structure, and the end peripheral wall of the joint shaft 22 is configured as a first joint surface 22a such that the first joint surface 22a and the second joint surface 30b abut against each other in the circumferential direction, and the air guide port 20a is provided through the first joint surface 22 a; therefore, the negative pressure adsorption function of the corresponding suction cup 10 can be turned on or off by the connection or disconnection between the air guide opening 20a and the air guide groove 30a during the rotation of the joint shaft 22 relative to the air guide 30.

Based on this, on one hand, when the joint shaft 22 rotates with the bearing seat 21 about its axial center line or rotation axis L1, the abutting relationship between the two joint surfaces can be utilized, so that one of the air guide ports 20a is in sealed communication with the air guide groove 30a, and the other air guide port 20a is sealed and closed by the surface area of the second joint surface 30b between the head end and the tail end of the air guide groove 30 a. On the other hand, the engaging shaft 22 is engaged with the air guide 30, which provides an advantage for reducing the size of the air guide 30 and thus the entire feeding device.

In one embodiment, referring to fig. 3, 4 and 5, the air guide member 30 includes a fixing base 31, an air guide base 32 and an elastic member 33; wherein, the fixed seat 31 is arranged at one end of the joint shaft 22 at intervals along the axial direction of the joint shaft 22, the fixed seat 31 can be fixedly arranged at a preset position (such as on the body of the driving assembly 50, or on other immovable component or part of the feeding device), the air guide seat 32 is fixedly arranged between the fixed seat 31 and the joint shaft 22, the surface of the guide seat 32 facing to one side of the joint shaft 22 along the axial direction of the joint shaft 22 is configured as a second joint surface 30b, so that the first joint surface 22a and the second joint surface 30b face each other along the axial direction of the joint shaft 22; the elastic member 33 is an elastic component having a preset expansion length, such as a spring, a spring tube, an elastic column, etc., one end of the elastic member 33 abuts against the air guide seat 32, and the other end abuts against the fixing seat 31, so that the air guide seat 32 can be pressed toward the side where the joint shaft 22 is located by means of the elastic force of the elastic member 33, and the second joint surface 30b can tightly abut against the first joint surface 22a, thereby ensuring that the joint shaft 22 (specifically, the first joint surface 22 a) does not leak air at the joint part of the joint shaft 22 and the air guide 30 in the process of rotating or stopping relative to the air guide 30 (specifically, the second joint surface 30 b).
