Description

Technical Field

[0001] The utility model belongs to the technical field of automatic production equipment, and particularly relates to a carrier for a switch automatic assembly machine. Background Art

[0002] Switches are one of the commonly used accessories on equipment and instruments, and the demand is very huge. Among them, the switch assembly machine of this application is used to assemble a product structure as Figures 1-3 shown, including: a base 100, a middle plate 200, buckle feet 300, screws 400 and nut pieces 500. The base 100 is inserted and matched with the middle plate 200. The outer periphery of the base 100 has a "one"-shaped socket 110. There are multiple such sockets 110, preferably four, and they are symmetrically arranged on the left and right sides of the base 100. The left and right side plates of the middle plate 200 have pins 210 that can be inserted downward into the corresponding sockets. The lower end of the pin 210 has a plug 211 that extends out of the socket. During installation, the plug 211 is twisted to be misaligned with the "one"-shaped socket 110, so as to prevent the plug 211 from protruding upward out of the "one"-shaped socket 110, and the installation of the base 100 and the middle plate 200 is realized; buckle feet 300 are distributed on the left and right sides of the base 100, and both sides of the buckle feet 300 are fastened to the middle plate 200 through the cooperation of screws 400 and nut pieces 500. Installation holes 600 are provided on the plate surface of the middle plate 200, the upper ends of the buckle feet 300, and the nut pieces 500. During installation, the screw 400 passes downward through the installation holes 600 of the middle plate 200, the buckle feet 300, and the nut pieces 500 in sequence. The screw 400 is in threaded cooperation with the nut piece 500. The upper end of the buckle foot 300 is fastened between the nut piece 500 and the plate surface of the middle plate 200. Positioning holes 220 are provided at the four corner positions of the plate surface of the middle plate 200. The left and right side plates of the middle plate 200 have extension pieces 230 corresponding to the lower sides of the installation holes on its plate surface. The lower end of the screw 400 also passes through the extension piece 230, and the tail end of the screw 400 extending out of the extension piece 230 is flattened to form a pressing head 410.

[0003] In the existing production process, most of the switch assembly depends on manual operation. Manual assembly not only has low efficiency, but also it is difficult to guarantee the product quality, and the production cost is relatively high. Although there are some automated assembly devices on the market, due to the special structure of this switch product, the existing automated machines cannot be applied to the assembly of this switch product, and it is difficult to achieve efficient and accurate automated assembly. Therefore, there is an urgent need for an automatic assembly machine suitable for this switch product, and for the key carrier part, it is necessary to meet the loading and matching requirements during the process of fastening the buckle feet with screws. Summary of the Utility Model

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a carrier for a switch automatic assembly machine. This design allows the positional relationship between the support and the middle plate mounting holes to be flexibly adjusted as needed during the assembly process, thereby facilitating the insertion of screws.

[0005] The technical solution of the utility model is: a carrier of a switch automatic assembly machine, comprising:

[0006] Carrier,

[0007] A bearing column, disposed on the carrier, for supporting the middle plate;

[0008] A pair of opposed bearing platforms are arranged on the carrier, and the opposite ends of the pair of bearing platforms have support platforms for supporting nut plates and buckle feet. The support platforms have through holes for screws to pass through, and the opposite sides of the through holes of the pair of bearing platforms are open structures for allowing the screws to slide out of the through holes. The pair of bearing platforms have two states of sliding inwards and sliding outwards. When the pair of bearing platforms are in the close state, the mounting holes of the nut plates and buckle feet driven by the support platforms are connected to the mounting holes of the middle plate.

[0009] By adopting the above technical solution, the carrier is designed with a bearing column and a pair of opposing bearing platforms, thereby achieving effective support and positioning of the centering plate, nut plate and buckle foot.

[0010] During installation, the nut sheet and the buckle foot are placed on the support platform in sequence, and the mounting holes of the nut sheet and the buckle foot are aligned with the through holes of the support platform. A pair of bearing platforms can slide together or apart, so that the through holes of the support platform can be flexibly aligned or misaligned with the mounting holes of the middle plate, meeting the load-bearing and matching requirements in the process of screw-fastening the buckle foot. When a pair of bearing platforms slide together, the pair of supports drive the nut sheet and the buckle foot placed thereon to slide inward, so that the mounting holes of the nut sheet and the buckle foot and the through holes of the support platform are aligned with the mounting holes of the middle plate, and a screw-through channel is formed, and then the screw is driven downward to achieve the screw and nut sheet to fasten the buckle foot to the middle plate; then the pair of bearing platforms slide away, and since the screws, nut sheet and buckle foot are assembled on the middle plate, the screws therein slide out relatively from the side openings of the through holes, so that the middle plate will not be interfered by the support platform, and it is easy to take it out upward. This design allows the positional relationship between the support and the middle plate mounting holes to be flexibly adjusted as needed during the assembly process, making it easier to thread and tighten the screws, greatly simplifying the assembly process and reducing the difficulty of operation.

[0011] The utility model is further configured as follows: a pair of bearing platforms slide along the X-axis, a follower actuator that can slide along the Y-axis is provided on the carrier, and the follower actuator drives the pair of bearing platforms to slide together or away from each other along the X-axis through a steering mechanism.

[0012] With the above further settings, the follower actuator slides along the Y-axis, and through the steering mechanism, it can accurately control the relative sliding, approaching or moving away, of a pair of carrier platforms. This design greatly enhances the flexibility and accuracy of assembly.

[0013] A further setting of the present utility model: The steering mechanism includes an inclined slot and a guide post. The inclined slot is provided on the follower actuator or the carrier platform, and the guide post is correspondingly linked with the carrier platform or the follower actuator. The guide post is inserted into the inclined slot, and the inclination directions of a pair of inclined slots are opposite. When the follower actuator slides, a pair of guide posts abut against the inner walls of the corresponding inclined slots, thereby driving the pair of carrier platforms to slide closer or move away.

[0014] With the above further settings, this design of the steering mechanism enables the follower actuator to control the sliding direction of the carrier platform along the X-axis when sliding along the Y-axis through the cooperation of the inclined slot and the guide post. The inclination directions of a pair of inclined slots are opposite, ensuring that when the follower actuator slides, the pair of carrier platforms can slide closer or move away respectively, realizing flexible and precise adjustment.

[0015] A further setting of the present utility model: The follower actuator is provided with a thrust-receiving surface for receiving an external force. When the push rod of the telescopic actuator extends and abuts against the thrust-receiving surface, it pushes the follower actuator to slide towards one end; after the push rod of the telescopic actuator disengages from the thrust-receiving surface of the follower actuator, an elastic resetting member provided on the carrier seat acts on the follower actuator and drives it to slide back towards the other end.

[0016] With the above further settings, by providing a thrust-receiving surface on the follower actuator, it is convenient to use the push rod of the telescopic actuator to push it and slide towards one end; and when the push rod disengages from the thrust-receiving surface, an elastic resetting member provided on the carrier seat, such as a spring, can automatically act on the follower actuator and drive it to slide back towards the other end. This design is not only simple in structure but also convenient in operation, and can effectively control the pair of carrier platforms in the approaching state and the separated state, further improving the automation degree and assembly efficiency of the switch assembly machine.

[0017] A further setting of the present utility model: The support platform has notches for accommodating the nut pieces and the upper ends of the buckle feet. The opposite sides of a pair of notches are of an open structure for enabling the nut pieces and the upper ends of the buckle feet to slide out of the notches, and the through holes are correspondingly at the bottoms of the notches.

[0018] With the above further settings, the notch on the carrier table is ingeniously designed to accommodate the nut piece and the upper end of the buckle leg, which can stabilize the positions of these components during the assembly process. Moreover, the opposite side of the notch adopts an open structure. This design enables the nut piece and the upper end of the buckle leg to smoothly slide out of the notch after completing the necessary assembly steps, facilitating the subsequent processes. Meanwhile, the through-hole is located at the bottom of the notch. Such a layout ensures that bolts or other fasteners can accurately pass through the through-hole and tightly combine with the nut piece, thereby further enhancing the structural stability and assembly accuracy of the switch assembly machine. This design not only optimizes the assembly process but also improves the overall assembly efficiency and reliability.

[0019] Further setting of the present utility model: A pair of carrier tables protrude from the bearing table in opposite directions.

[0020] With the above further settings, the protruding carrier tables facilitate sending the nut pieces and the upper ends of the buckle legs thereon between the extension pieces on the plate surface of the middle plate.

[0021] Further setting of the present utility model: There are multiple bearing columns, and they have positioning heads inserted into the positioning holes on the middle plate. The top ends of the positioning heads are conical.

[0022] With the above further settings, there are multiple bearing columns, and their upper end surfaces are used to support the middle plate. And each bearing column is equipped with a positioning head, which can accurately insert into the positioning holes on the middle plate. The conical design of the top ends of the positioning heads not only facilitates the quick and accurate installation of the positioning heads but also effectively prevents the problems of misalignment or shaking that may occur during the assembly process.

[0023] Further setting of the present utility model: The carrier seat is arranged on the trolley. The bottom surface of the trolley is provided with wheels that can move on the guide rail, and the trolley is provided with a linkage seat connected to the conveyor belt.

[0024] With the above further settings, the carrier seat is installed on the trolley, enabling the entire carrier to have the ability to move flexibly. The wheels provided on the bottom surface of the trolley can move smoothly on the guide rail, and the trolley is provided with a linkage seat connected to the conveyor belt. This design enables the trolley to run on the guide rail under the drive of the conveyor belt. Brief Description of the Drawings

[0031] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0032] As Figures 4-6 shown, the technical solution of the present utility model: A carrier of a switch automatic assembly machine includes:

[0033] A carrier base 1;

[0034] Support columns 2 are arranged on the carrier base 1 and are used to support the middle plate. There are multiple support columns 2, and each support column 2 has a positioning head 21 inserted into the positioning holes on the middle plate. The top of the positioning head 21 is conical;

[0035] A pair of opposed carrier tables 3 are arranged on the carrier base 1. The relative ends of the pair of carrier tables 3 have a support table 31 for supporting the nut piece and the buckle foot. The support table 31 has a notch 312 for accommodating the upper ends of the nut piece and the buckle foot. The opposite sides of the pair of notches 312 are of an open structure for allowing the upper ends of the nut piece and the buckle foot to slide out of the notch 312. The support table 31 has a through hole 311 through which a screw can pass. The through hole 311 corresponds to the bottom of the notch 312. The opposite sides of the through holes of the pair of support tables 3 are of an open structure for allowing the screw to slide out of the through hole 311. Among them, the pair of carrier tables 3 can slide inward to approach or slide outward to move away from each other, so as to have two states of approaching and moving away. When the pair of carrier tables 3 are in the approaching state, the mounting holes of the nut piece and the buckle foot carried by the support table 31 are aligned with the mounting holes of the middle plate. The pair of support tables 3 protrude in the relative direction from the carrier table 3.

[0036] Specifically, a pair of carrier tables 3 slide along the X-axis and cooperate with the carrier base 1 through guide rails and guide grooves along the X-axis. A follower actuator 4 capable of sliding along the Y-axis is provided on the carrier base 1. The follower actuator 4 cooperates with the carrier base 1 through guide rails and guide grooves along the Y-axis. The follower actuator 4 drives a pair of carrier tables 3 to slide closer or farther away along the X-axis through a steering mechanism. The X-axis can be the left-right direction, the Y-axis can be the front-back direction, and a pair of carrier tables 3 are arranged opposite to each other left and right. The steering mechanism includes the cooperation of an inclined groove 51 and a guide post 52, or other steerable structures. The inclined groove 51 is directly or indirectly provided on the follower actuator 4 or the carrier table 3. The guide post 52 is correspondingly linked with the carrier table 3 or the follower actuator 4. The guide post 52 is inserted into the inclined groove 51, and the inclination directions of a pair of inclined grooves 51 are opposite. For example, one inclines upward to the left, and the other inclines upward to the right. When the follower actuator 4 slides, a pair of guide posts 52 abut against the inner walls of the corresponding inclined grooves 51, thereby driving a pair of carrier tables 3 to slide closer or slide farther away. The carrier table is fixedly or integrally provided on the guide rail, a guide groove along the X-axis is provided on the carrier base, and the guide rail and the guide groove cooperate to slide. The guide post 52 is fixedly or integrally provided on the guide rail. When there is one follower actuator 4, a pair of inclined grooves 51 are provided on one follower actuator 4. When there are two follower actuators 4, one inclined groove 51 is provided on each respective follower actuator 4.

[0037] Specifically, the follower actuator 4 is provided with a thrust-receiving surface 41 for receiving an external force. When the push rod of the telescopic actuator mechanism extends and abuts against the thrust-receiving surface 41, the follower actuator 4 is pushed to slide towards one end. After the push rod of the telescopic actuator mechanism disengages from the thrust-receiving surface 41 of the follower actuator 4, the elastic resetting member provided on the carrier base 1 acts on the follower actuator 4 and drives it to slide back to the other end to reset when the current pair of carrier tables 3 are in a separated state. The elastic resetting member is a spring, a tension spring, etc. One end of it is connected to the carrier base, and the other end is connected to the follower actuator 4, or the elastic resetting member directly acts on a pair of carrier tables 3.

[0038] Specifically, the carrier base 1 is provided on a trolley 6. The carrier base 1 is fixedly connected to the trolley 6 by screws or integrally connected. Wheels 61 capable of traveling on the guide rail are provided on the bottom surface of the trolley 6. The trolley 6 is provided with a linkage seat 62 connected to a transmission belt.

[0039] Working principle:

[0040] First, the nut pieces and buckle feet are automatically placed on the support platforms 31 of a pair of carrier tables 3 through a feeding device or a robotic arm, and the mounting holes of the nut pieces and buckle feet are aligned with the through holes 311 of the support platforms 31. Then, the middle plate is automatically placed on a plurality of support columns 2 through the robotic arm.

[0041] When the carrier base 1 corresponds to the telescopic actuator 7, a command is issued through the control system, and the push rod of the telescopic actuator 7 extends and abuts against the pushed surface 41 of the follower actuator 4, pushing the follower actuator 4 to slide towards one end in the Y-axis direction. The follower actuator 4 drives a pair of carrier platforms 3 to slide relatively closer in the X-axis direction through the steering mechanism, that is, the cooperation of the inclined slot 51 and the guide post 52. The pair of support platforms 31 drive the nut pieces and buckle feet placed thereon to slide inwards, so that the mounting holes of the nut pieces and buckle feet and the through holes of the support platforms are aligned with the mounting holes of the middle plate, forming a screw passing channel. Then, the screw is driven downwards to realize the cooperation of the screw and the nut piece to fasten the buckle foot to the middle plate. At this time, the pair of carrier platforms are in the closed state;

[0042] After the push rod of the telescopic actuator 7 disengages from the pushed surface 41, the elastic reset member provided on the carrier base 1, such as a spring, can automatically act on the follower actuator 4, driving it to slide and reset towards the other end of the Y-axis, thereby driving the pair of carrier platforms 3 to slide away. Since the screw, nut piece, and buckle foot are assembled on the middle plate, the screw slides out relatively from the side opening of the through hole 311, and the upper ends of the nut piece and buckle foot slide out relatively from the side opening of the notch 312. At this time, the pair of carrier platforms 3 are in the separated state. This design is not only simple in structure but also convenient in operation, and can effectively control the pair of carrier platforms in the closed state and the separated state, further improving the automation degree and assembly efficiency of the switch assembly machine.

[0043] Moreover, the trolley 6 is driven by the conveyor belt and walks smoothly on the guide rail through the wheels 61, and can move the carrier system to the next station for the next round of assembly operation.

[0044] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back...) are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0045] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "coupling", "connection", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
