Description

Technical Field

[0001] This utility model belongs to the field of automated assembly technology, and in particular relates to an indexing feed separation mechanism. Background Technology

[0002] In the field of humanoid robots, articulated arm nuts require the adhesion of magnets to the outer wall of the nut. The usual method is to brush glue onto the outer wall of the nut, then place the magnet into a special mold, and push the mold to attach the magnet to the outer wall of the nut, thus adhering the magnet through glue. However, the usual method of pushing the mold one by one to adhere the magnet to the nut is inefficient. This paper proposes a structure that can push multiple magnets to adhere simultaneously. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an indexing feed separation mechanism that solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an indexing feed separation mechanism, comprising an indexing propulsion ring, wherein the upper surface of the indexing propulsion ring is symmetrically provided with a plurality of arc-shaped grooves extending to its lower surface, and a guide plate is coaxially provided above the indexing propulsion ring, and the indexing propulsion ring and the guide plate rotate relative to each other. The guide plate is provided with a guide groove extending from its upper surface to its lower surface, the guide groove and the arc-shaped grooves corresponding to each other, and a guide block is slidably disposed in each of the plurality of guide grooves, the lower end of the guide block being located in the corresponding arc-shaped groove.

[0005] Beneficial effects

[0006] This utility model provides an indexing feed separation mechanism, which has the following advantages compared with the prior art:

[0007] When workers need to attach magnets to the nuts of a robot articulated arm, the molds containing magnets should be symmetrically placed on the guide blocks, and the nuts of the robot articulated arm should be inserted into the through holes at the axis of the guide plate. Then, the indexing advance ring and the guide plate can be rotated relative to each other by the drive assembly. At this time, the guide plate is stationary while the indexing advance ring is rotating. During the rotation of the indexing advance ring, the lower end of the guide block can begin to slide relative to the arc groove. At this time, the contact area between the lower end of the guide block and the arc groove gradually changes. Under the limiting action of the arc groove, the lower end of the guide block begins to slide towards the axis of the indexing advance ring. That is, the guide block begins to slide towards the axis of the guide plate in the guide groove. This achieves the synchronous sliding of multiple guide blocks towards the axis of the guide plate. At this time, the push rods on the guide blocks will push the molds containing magnets onto the nuts of the robot articulated arm, and the magnets will be adhered to them by the glue applied to the nuts of the robot articulated arm.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0014] Please see Figures 1-3 This invention provides an indexing feed separation mechanism according to one embodiment of the present invention, comprising an indexing advance ring 5. The upper surface of the indexing advance ring 5 is symmetrically provided with multiple arc-shaped grooves 9 extending to its lower surface. A guide plate 7 is coaxially disposed above the indexing advance ring 5, and the indexing advance ring 5 and the guide plate 7 rotate relative to each other. The guide plate 7 is provided with guide grooves 11 extending from its upper surface to its lower surface. The guide grooves 11 correspond to the arc-shaped grooves 9, and guide blocks 6 are slidably disposed in each of the multiple guide grooves 11. The lower end of each guide block 6 is located in its corresponding arc-shaped groove 9. The sidewall of the guide block 6 should fit against the inner wall of the guide groove 11 to ensure that the multiple guide blocks 6 can slide synchronously toward the axis of the guide plate 7. During installation, the guide plate 7 should be fixed in the required installation position with bolts to ensure that the guide plate 7 remains stationary when the indexing advance ring 5 rotates.

[0015] Specifically, each of the multiple guide blocks 6 is symmetrically fixedly connected with a push rod 12, and the push rod 12 is vertically arranged on the upper surface of the guide block 6. The guide block 6 is used to push the mold in which the magnet is placed.

[0016] In the above embodiment, when the operator needs to attach the magnet to the nut of the robot joint arm, the mold containing the magnet should be symmetrically placed on the guide block 6, and the nut of the robot joint arm should be inserted into the through hole at the axis of the guide plate 7. Then, the indexing push ring 5 and the guide plate 7 can be rotated relative to each other by the drive component. At this time, the guide plate 7 is stationary when the indexing push ring 5 rotates. Thus, during the rotation of the indexing push ring 5, the lower end of the guide block 6 can begin to slide relative to the arc groove 9. At this time, the contact area between the lower end of the guide block 6 and the arc groove 9 gradually changes. Under the limiting action of the arc groove 9, the lower end of the guide block 6 begins to slide towards the axis of the indexing push ring 5. That is, the guide block 6 begins to slide towards the axis of the guide plate 7 in the guide groove 11. Thus, multiple guide blocks 6 slide towards the axis of the guide plate 7 simultaneously. At this time, the push rod 12 set on the guide block 6 pushes the mold containing the magnet toward the nut of the robot joint arm, and the magnet is adhered to it by the glue applied to the nut of the robot joint arm.

[0017] In some examples, the bottom of the mold containing the magnet should be provided with a slot that matches the push rod 12, so that the mold can be vertically inserted into the push rod 12, thereby increasing the stability of the mold and preventing the mold from falling or sliding during the process of the push rod 12 pushing the mold.

[0018] Specifically, in the initial position, the end of the arc-shaped groove 9 away from the axis of the indexing and propulsion ring 5 is coaxial with the end of the corresponding guide groove 11 away from the axis of the guide plate 7, and the guide block 6 is located on the end of the guide groove 11 away from the axis of the guide plate 7 in the initial position.

[0019] Specifically, each of the lower ends of the multiple guide blocks 6 is rotatably connected to a needle roller bearing 10, and the diameter of the needle roller bearing 10 is smaller than the width of the arc groove 9.

[0020] In some examples, the outer wall of the needle roller bearing 10 may be covered with an anti-slip rubber pad. The purpose of this arrangement is to ensure that the needle roller bearing 10 can roll in the arcuate groove 9.

[0021] In the above embodiment, since the needle roller bearing 10 rotatably disposed at the lower end of the guide block 6 is located in the arc groove 9, and the diameter of the needle roller bearing 10 of the servo motor 1 is smaller than the width of the arc groove 9, during the rotation of the indexing advance ring 5, one side of the inner wall of the arc groove 9 can be made to fit against the outer wall of the needle roller bearing 10, thereby causing the needle roller bearing 10 to start rolling on the side of the inner wall that fits against the arc groove 9. That is, the lower end of the guide block 6 can roll in the arc groove 9 through the needle roller bearing 10, thereby providing sliding guidance for the guide block 6 and effectively reducing the damping of the sliding of the lower end of the guide block 6.

[0022] Specifically, the indexing advance ring 5 is provided with a drive assembly for rotating relative to the guide plate 7. The drive assembly includes a pulley B8, which is coaxially fixedly connected to the lower surface of the indexing advance ring 5, and a synchronous belt 3 is drivenly connected to the pulley B8. The other end of the synchronous belt 3 is drivenly connected to the pulley A2.

[0023] In some examples, to avoid elastic slippage of the timing belt 3, those skilled in the art can replace the timing belt 3 with a chain, and replace pulley A2 and pulley B8 with sprockets respectively, with the sprockets meshing with the chain to increase the accuracy of transmission.

[0024] Specifically, the pulley A2 is coaxially fixedly connected to the output shaft of the servo motor 1, and the servo motor 1 is vertically arranged on the side of the guide plate 7; during installation, the servo motor 1 should be fixed in its preset installation position by bolts to avoid vibration during operation.

[0025] In the above embodiment, the user can start the servo motor 1, so that the pulley A2 fixedly connected to its output shaft starts to rotate at a constant speed. At this time, under the action of the synchronous belt 3, the pulley B8 can rotate synchronously with the pulley A2. In order to avoid the problem of elastic slippage, those skilled in the art should check the tightness of the synchronous belt 3 regularly to prevent the synchronous belt 3 from becoming loose and causing the pulley B8 to be unable to rotate synchronously with the pulley A2. That is, when the servo motor 1 is started, the indexing advance ring 5 can start to rotate.

[0026] In some examples, the servo motor 1 should be integrated with a switch for controlling its rotation and a power supply for supplying power to it.

[0027] Specifically, a cross roller bearing 4 is coaxially arranged at the shaft center of the pulley B8, and the pulley B8 is rotatably connected to the cross roller bearing 4. The guide plate 7 is also rotatably connected to the cross roller bearing 4. Due to the presence of the cross roller bearing 4, the friction suffered by the pulley B8 during rotation can be effectively reduced, thereby effectively reducing its wear.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0030] (Servo Motor 1) Detachable Connection: Components are fixed together using screws, splines, wedges, etc. This connection method allows for disassembly during maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of bolts, keys, and wedges) and properly tightened.

[0031] (Pulley A2) Non-detachable connection: mainly refers to welding, riveting, and tenon joints. Because disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, during connection, [the following should be noted]:

[0032] Pay attention to process quality, technical testing, and remedial measures (such as correction, polishing, etc.).

[0033] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0034] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
