Description

Technical Field

[0001] This invention relates to the field of automatic relay assembly, and in particular to an automatic assembly device for relay terminals and frames. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity changes to a specified value. It has an interactive relationship between the control system (input circuit) and the controlled system (output circuit); it is commonly used in automated control circuits, and is essentially an "automatic switch" that uses a small current to control a large current; it plays roles in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] The relay structure comprises components such as a relay housing, relay coil, relay frame, moving terminal, and stationary terminal. The relay housing is a box-shaped structure with an open top, containing an internal mounting cavity. This cavity is divided into multiple independent spaces by vertical partitions for mounting the relay coil, relay frame, moving terminal, and stationary terminal respectively. Based on relay installation requirements, the relay frame must be vertically inserted near one side wall of the relay housing. Simultaneously, the stationary and moving terminals must be vertically inserted into the relay housing, ensuring that the contacts on their springs are aligned and in contact to achieve electrical conduction. Based on these installation requirements, a device is needed to automatically assemble the relay frame and moving terminal. During assembly, the relay frame must first be precisely inserted vertically into the slot within the relay housing. Then, the moving terminal must be inserted through the relay housing into the relay frame. The relative positions of the relay frame and moving terminal, as well as the relative positions of the moving terminal and relay housing, must be precisely maintained throughout the assembly process.

[0020] The beneficial effects of this invention are as follows: This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing an automatic assembly device for relay terminals and frames that achieves efficient and precise installation of relay housings and moving terminals, effectively improving installation efficiency and accuracy. It also features an adaptive bidirectional synchronous linkage flexible clamping function, ensuring the stability of relay housing clamping during assembly while improving the synchronicity and efficiency of carrier opening and closing, and reducing opening and closing energy consumption.

[0021] This invention aims to provide a solution for the automatic assembly of relays, enabling the automatic assembly of the relay frame and moving terminal onto the relay housing. During assembly, it effectively ensures the positional stability of the relay frame and the relative positional stability between the relay housing, the relay frame, and the moving terminal, thereby improving installation accuracy and efficiency. Specifically, the invention comprises a carrier, a guiding and pushing mechanism, a rotary feeding mechanism, a picking mechanism, and a pushing mechanism. The carrier is horizontally positioned for clamping, positioning, and fixing the relay housing during assembly. The rotary feeding mechanism is located on the side of the carrier, receiving the relay frame from an external mechanism and rotating it from a horizontal to a vertical position for clamping by the picking mechanism. After vertically clamping and fixing the picked-up relay frame, the picking mechanism places it into the guiding and pushing mechanism on the side of the carrier. The guiding and pushing mechanism inserts into the relay housing within the carrier, simultaneously forming a vertical and horizontal guiding channel. The rotary feeding mechanism horizontally receives the relay frame transported by the external mechanism. After the relay frame is transported to the bottom of the material handling mechanism, it is rotated to a vertical position. The material handling mechanism vertically removes the relay frame from the rotating material receiving mechanism and places it into the guide channel in the vertical direction of the guide pushing mechanism. The guide pushing mechanism then pushes the relay frame into the relay housing, completing the mutual assembly between the relay frame and the relay housing. After the relay frame is assembled, the moving terminal, which has been placed in the relay housing beforehand, needs to be pushed into the relay frame. The pushing mechanism on the side of the carrier pushes the moving terminal on the relay housing horizontally, so that the moving terminal is gradually embedded into the relay frame along the guide channel in the horizontal direction formed by the guide pushing mechanism, completing the relative assembly between the moving terminal and the relay frame.

[0022] To address the problem of clamping and positioning relay housings during installation, this invention designs a carrier. The carrier uses a horizontally positioned carrier base as its supporting structure. The carrier base is equipped with an L-shaped limiting block, which forms an installation space with openings on both sides above the carrier base for placing the relay housing. The two inner sidewalls of the limiting block serve as positioning reference surfaces. The two open sides of the installation space are respectively equipped with a first pressing block and a second pressing block, which are used to clamp and position the relay housing placed in the installation space to ensure the positional stability of the relay housing during installation. The unique feature is that the first and second pressure blocks of this invention have adaptive flexible clamping and fixing, and realize the linkage synchronous opening and closing function of a single power drive; specifically, this invention has two sliding rods inserted parallel and spaced apart in the carrier seat, the two sliding rods are slidably inserted in the carrier seat, one end of the two sliding rods is vertically provided with a first sliding seat, and the other end is vertically provided with a second sliding seat, thereby forming an integral rectangular frame structure, and the rectangular frame structure slides freely in the carrier seat; the second pressure block is set on the second sliding seat and is located at one side opening of the installation space; the first sliding seat is vertically provided with an inclined push rod, the inclined push rod extends to the other side opening of the installation space, and its outer side is provided with a pushing slope; the inclined push rod is inserted into the first pressure block of the U-shaped structure. Inside the block, a guide seat is provided on the top of the first pressing block. The first pressing block slides freely in the second through groove below the guide seat and is connected to the inner wall of the second through groove through a compression spring. In its natural state, the elastic force of the compression spring tends to drive the first pressing block to move towards the installation space so as to flexibly clamp and fix the relay housing in the installation space. At the same time, a slide spring is sleeved on the slide rod between the first slide and the carrier seat. In its natural state, the elastic force of the slide spring tends to push the first slide outward. At this time, the first slide drives the inclined push rod to move outward, so that the first pressing block clamps and fixes the relay housing under the action of the compression spring. Simultaneously, the second slide drives the second pressing block to move towards the installation space, realizing the linkage and synchronous clamping and fixing of both sides. When an external force is applied to the first slide block and overcomes the elastic force of the slide bar spring to push the first slide block towards the installation space, the first slide block pushes the second slide block and the second pressure block on it away from the installation space through the slide bar, releasing the relay housing; at the same time, the inclined push rod pushes the first pressure block outward through the inclined surface, causing it to move outward in the second through slot, releasing the relay housing. Thus, through single-power drive, the first and second pressure blocks are simultaneously driven open, effectively saving energy while ensuring linkage.

[0023] To address the issues of relay housing installation and positional misalignment when the moving terminal is embedded in the relay housing, this invention designs a guiding and pushing mechanism. The guiding and pushing mechanism is located on the side of the carrier and extends above it. A vertically positioned pushing bracket serves as the supporting structure. A lifting cylinder is located on one side of the pushing bracket, with its output end facing downwards. The lifting cylinder drives a lifting slide connected to it to move up and down. The bottom of the lifting slide is horizontally connected to a guide socket, and the top of the guide socket is equipped with a pushing guide seat. A pushing cylinder is located on the side wall of the lifting slide, with its output end facing upwards and horizontally connected to a pushing seat. A push rod is vertically connected to the bottom of the pushing seat. During assembly, the lifting cylinder first drives the lifting seat to insert the insertion guide seat into the relay housing. The insertion guide seat has a pushing guide that runs vertically upwards and downwards. The groove forms a vertical material guiding space, while the guide holes on the insertion guide form a horizontal material guiding space. The insertion guide, which is inserted into the relay housing, simultaneously forms both vertical and horizontal material guiding spaces. The vertical material guiding space is used for guiding and limiting when assembling the relay frame, ensuring the positional accuracy of the relay frame when inserted into the relay housing. The horizontal material guiding space is used for guiding and limiting when assembling the moving terminal, ensuring both the positional stability of the relay frame and the precise insertion of the moving terminal into the relay frame. After the relay frame to be assembled is placed into the push guide groove from above, the push cylinder drives the push rod to move downward. The push rod passes through the push guide and inserts downward into the push guide groove, pushing the relay frame in the push guide groove into the relay housing. During the downward pushing process, the push rod is guided and limited by the guide holes on the push guide.

[0024] To address the issue of automatic feeding of relay frames during assembly, this invention designs a rotary feeding mechanism. This mechanism includes a horizontal support, a transverse support assembly, a rotary drive assembly, and a rotary head. The horizontal support is horizontally positioned on the side of the carrier. The transverse support assembly is mounted on the horizontal support and outputs power vertically to drive the rotary drive assembly and rotary head to move back and forth linearly between the receiving position and the picking position. The transverse support assembly drives the rotary drive assembly and rotary head to the receiving position to horizontally receive the relay frames transported by the external loading mechanism, and simultaneously moves the received relay frames to the picking position for the picking mechanism to pick them up. During the transfer of the relay frame, the rotary drive assembly drives the rotating head to rotate the relay frame from a horizontal direction to a vertical direction, so that the material handling mechanism can vertically remove the relay frame. The key feature is that the rotary drive assembly of this invention uses a rotary drive cylinder horizontally mounted on a transverse support as its power source. The rotary drive cylinder pushes a drive rack to move back and forth linearly on the transverse support. The drive rack meshes with drive teeth fitted on a rotating shaft rotatably inserted into a transverse slide above it. Through this toothed connection, the linear motion of the drive rack is converted into the rotational motion of the drive teeth. When the drive teeth drive the rotating shaft to rotate, the rotating shaft drives the rotating head connected to its end to rotate, so as to remove the relay frame vertically. The relay frame inside rotates from a horizontal to a vertical direction; furthermore, the rotating head of the present invention is vertically arranged, and a rotating seat connected to the rotating shaft serves as a bearing structure. A material trough is provided on the top of the rotating seat, with openings on the top and other sides. The top opening is used to pick up and place the relay frame, and the side opening is used to support or fix the relay frame inside the material trough. Specifically, a support seat is horizontally provided on the other side wall of the rotating seat, located below the material trough; a support shaft is horizontally provided inside the material trough, and a rotating pressure seat is rotatably fitted on the support shaft. The bottom and top of the rotating pressure seat extend to the upper and lower sides of the support shaft, respectively; a clamping cylinder is horizontally provided on the support seat. The output end is connected to the lower side of the outer wall of the rotary pressure seat. When the pressure cylinder outputs power to push the lower part of the rotary pressure seat, it causes the rotary pressure seat to rotate around the support shaft. A rotary spring is provided on the lower inner side of the rotary pressure seat. One end of the rotary spring abuts against the inner wall of the rotary pressure seat, and the other end abuts against the inner wall of the material trough. Under normal conditions, the elastic force of the rotary spring pushes the lower part of the rotary pressure seat outward, causing the rotary pressure seat to rotate around the support so that the rotary pressure plate set on the upper part of the inner wall of the rotary pressure seat is pressed into the material trough to lift or press the relay frame in the material trough. When it is necessary to remove or put away the relay frame, the pressure spring pushes the lower part of the rotary pressure seat from the outside, causing the rotary pressure plate on the upper part of the rotary pressure seat to be pulled out of the material trough.

[0025] To address the issue of automatic material handling and transfer of relay frames, this invention includes a material handling mechanism. After the material handling mechanism removes the relay frame, which has been rotated to a vertical position, from the rotary feeding mechanism, it maintains the vertical position and inserts it into the pusher groove of the guide mechanism to embed the relay frame into the relay housing. Specifically, the material handling mechanism uses a vertically positioned material handling bracket as its supporting structure. A horizontally positioned material handling transverse cylinder on the material handling bracket provides horizontal power to transfer the relay frame between the rotary feeding mechanism and the carrier. The material handling transverse cylinder drives the material handling transverse seat to move horizontally, thereby driving a material handling lifting cylinder on its side wall. The material handling lifting cylinder provides vertical power to drive the material handling head to move up and down, thus feeding the relay frame downward into the pusher groove. Furthermore, due to the difference between the material picking angle and the installation angle, the material picking head of this invention has the function of adjusting the angle in the horizontal plane. The material picking head uses a material picking support plate as a load-bearing structure. A material picking support is provided on the side wall of the material picking support plate. A rotating shaft is vertically rotatable inside the material picking support. A rotating gear is sleeved on the rotating shaft inside the material picking support. A horizontal groove is provided on the outside of the rotating shaft. A material picking rack is slidably provided in the horizontal groove. The material picking rack is meshed with the rotating gear. When the material picking rotary cylinder drives the material picking rack to move horizontally in the horizontal groove, the material picking rack drives the rotating gear to rotate the rotating shaft. The mechanism involves a rotating shaft and a rotating gear. The linear motion of the rotary cylinder is converted into rotational power in the horizontal plane through the meshing connection between the drive rack and the rotating gear, thereby achieving rotational drive of the rotating shaft. The rotating shaft extends to the bottom of the material-picking support, where a material-picking rotating seat is located. A clamping cylinder is connected to the bottom of the material-picking rotating seat. The clamping cylinder drives two clamping blocks connected to its lower output end to move relative to or towards each other, which is used to remove the vertically set relay frame from the rotary feeding mechanism. At the same time, the rotating shaft drives the clamping cylinder and the clamped relay frame to rotate in the horizontal plane, which is used to adjust the angle of the relay frame.

[0026] To address the issue of automatic insertion of moving terminals, this invention incorporates a pushing mechanism. This mechanism is located on the side of the carrier and uses a vertically mounted pushing bracket as its support structure. A pushing lifting cylinder is located on one side of the pushing bracket to provide vertical power. The pushing lifting cylinder drives the pushing lifting seat to move up and down, adjusting the vertical height. A pushing horizontal seat is mounted on the pushing horizontal seat, and a pushing slide is slidably mounted on the pushing horizontal seat. The pushing slide is connected to the pushing horizontal seat via a pushing spring. In its natural state, the spring force maintains the pushing slide in one direction. The side-pulling tendency facilitates maintaining flexible contact with the moving terminal during the pushing or correction process, achieving elastic buffering. A pushing cylinder is provided on the pushing slide perpendicular to its sliding direction. The pushing cylinder drives the pushing block to output linear power in a direction perpendicular to the movement of the pushing slide. During pushing, the elastic force of the pushing spring drives the pushing slide to move the pushing cylinder and the pushing block above it closer to the moving terminal placed on the relay housing. The elastic force presses the moving terminal into the relay frame, while the pushing cylinder drives the pushing block to slide linearly on the side of the moving terminal, pushing the moving terminal into the relay frame in a line contact manner. Furthermore, as another embodiment, the pusher slide of the present invention can also be provided with a pusher head to replace the pusher cylinder and the pusher block. The pusher head includes a second pusher cylinder, a second pusher slide, a second pusher block, and a pusher guide block. The second pusher cylinder can be horizontally arranged on the pusher slide and outputs linear power in a direction perpendicular to the moving terminal. The second pusher slide is connected to the output end of the second pusher cylinder. The second pusher block is arranged on the second pusher slide and extends towards the moving terminal. The second pusher block has an inwardly recessed pusher groove on the side near the moving terminal. The pusher guide block is horizontally arranged above the pusher groove and extends horizontally towards the moving terminal. During the pusher process, the pusher groove is nested on the moving terminal from the outside and guided and positioned by the pusher guide block above to ensure the accuracy of its relative position with the moving terminal. The second pusher cylinder drives the second pusher block to push the moving terminal into the relay frame. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0065] Example 1: As Figures 1 to 5 As shown, this invention proposes an automatic assembly device for relay terminals and frames, used for automatically assembling relay frames and terminals. It includes a carrier 1, a guiding and pushing mechanism 2, a rotary feeding mechanism 3, a picking mechanism 4, and a pushing mechanism 5. The carrier 1 is horizontally positioned to support and clamp the relay housing 01 to be assembled. The guiding and pushing mechanism 2 is located on the side of the carrier 1 and extends above it, used to pick up the relay frame 02 to be assembled and insert it into the relay housing 01 on the carrier 1, forming a vertical channel, and pushing the relay frame 02 along the vertical channel into the carrier. Inside the electrical housing 01; the rotary feeding mechanism 3 is located on the side of the carrier 1, used to horizontally pick up the relay frame 02 to be assembled, and rotate the relay frame 02 to the vertical direction; the picking mechanism 4 is set between the carrier 1 and the rotary feeding mechanism 3, used to vertically clamp the relay frame 02 from the rotary feeding mechanism 3, and move the relay frame 02 into the vertical channel of the guide pushing mechanism 2; the pushing mechanism 5 is located on the side of the carrier 1, and the pushing mechanism 5 flexibly outputs horizontal power to push the moving terminal 04 into the relay housing 01.

[0066] like Figures 10 to 15 As shown, the relay housing 01 of the present invention is a box-shaped structure with an open top. The interior of the relay housing 01 is a mounting cavity, which is divided into two independent spaces by a partition. One independent space contains a relay coil; the other independent space contains a stationary terminal 03 and a moving terminal 04. One end of the other independent space has a relay frame 02 vertically inserted, and the other end is an open structure. The stationary terminal 03 is inserted into the other independent space in a direction perpendicular to the relay frame 02. The inner side of the stationary terminal 03 has a first slot D. The side wall of the relay housing 01 corresponding to the first slot D has a second slot E. The opening of the first slot D has an outwardly extending transition arc surface. The moving terminal 04 is inserted through the opening of the first slot D and passes through the relay frame 02 into the second slot E. The other end of the other independent space has a relay cover plate 05 vertically inserted, forming a relay assembly 0.

[0067] This invention designs an automatic assembly device for relay terminals and frames that achieves efficient and precise installation of the relay frame and moving terminals, effectively improving installation efficiency and accuracy. It also features an adaptive bidirectional synchronous linkage flexible clamping function, ensuring the stability of the relay housing during assembly while improving the synchronicity and efficiency of the carrier's opening and closing, and reducing energy consumption during opening and closing. This invention aims to provide a device applicable to the field of automatic relay assembly, enabling the automatic assembly of the relay frame and moving terminals onto the relay housing, effectively ensuring the positional stability of the relay frame during assembly, and ensuring the relative positional stability between the relay housing, the relay frame, and the moving terminals, thereby effectively improving installation accuracy and efficiency. Specifically, the present invention comprises a carrier, a guiding and pushing mechanism, a rotary feeding mechanism, a picking mechanism, and a pushing mechanism. The carrier is horizontally positioned for clamping, positioning, and fixing the relay housing during assembly. The rotary feeding mechanism is located on the side of the carrier and is used to pick up the relay frame from an external mechanism and rotate the relay frame from the horizontal direction to the vertical direction for clamping by the picking mechanism located on the side. After the picking mechanism vertically clamps and fixes the picked-up relay frame, it is placed in the guiding and pushing mechanism on the side of the carrier. The guiding and pushing mechanism is inserted into the relay housing inside the carrier, simultaneously forming a vertical guide channel and a horizontal guide channel. The rotary feeding mechanism horizontally picks up the relay frame transported by the external mechanism. After the relay frame is transported to the bottom of the material handling mechanism, it is rotated to a vertical position. The material handling mechanism vertically removes the relay frame from the rotating material receiving mechanism and places it into the guide channel in the vertical direction of the guide pushing mechanism. The guide pushing mechanism then pushes the relay frame into the relay housing, completing the mutual assembly between the relay frame and the relay housing. After the relay frame is assembled, the moving terminal, which has been placed in the relay housing beforehand, needs to be pushed into the relay frame. The pushing mechanism on the side of the carrier pushes the moving terminal on the relay housing horizontally, so that the moving terminal is gradually embedded into the relay frame along the guide channel in the horizontal direction formed by the guide pushing mechanism, completing the relative assembly between the moving terminal and the relay frame.

[0068] Example 2: As Figures 6 to 9 As shown, the carrier 1 of the present invention includes a carrier base 11, a limiting block 12, and a flexible clamping assembly. The carrier base 11 is horizontally arranged. The limiting block 12 has an L-shaped structure and is disposed on the carrier base 11. An installation space is formed on the inner side of the limiting block 12 for placing the relay assembly 0. The installation space is positioned with the two sides of the limiting block 12 as reference positioning surfaces, and the other two sides of the installation space are open structures. The flexible clamping assembly is disposed on the outer side of the installation space and moves inward from the other two sides of the installation space to flexibly clamp and fix the relay assembly 0.

[0069] The flexible clamping assembly includes a first slide block 13, a slide spring 14, a slanted push rod 15, a first pressure block 16, a pressure spring 17, a guide seat 18, a slide rod 19, a second slide block 110, and a second pressure block 111. The first slide block 13 and the second slide block 110 are respectively arranged parallel to each other on both sides of the carrier seat 11, and are connected by at least two slide rods 19. The at least two slide rods 19 are arranged parallel to each other and are slidably inserted into the carrier seat 11. The slide spring 14 includes at least two springs, each sleeved on one of the slide rods 19. One end of each slide spring 14 abuts against the inner wall of the first slide block 13, and the other end abuts against the outer wall of the carrier seat 11. In its natural state, the elastic force of the slide spring 14 pushes the first slide block 13 outwards, and the first slide block 13 drives the second slide block 110 to move closer to the carrier seat 11 via the slide rods 19.

[0070] The inclined push rod 15 is vertically connected to the first slide block 13 and extends above the carrier seat 11. The outer side of the end of the inclined push rod 15 is provided with a pushing inclined surface A. The guide seat 18 is a block structure, with a first through groove B and a second through groove C perpendicular to each other at its bottom. The first pressure block 16 is a U-shaped block structure, slidably disposed within the second through groove C. An inclined surface is provided on the inner wall of the first pressure block 16 corresponding to the pushing inclined surface A. The inclined push rod 15 passes through the first pressure block 16 and slides freely within the first through groove B. The inclined push rod 15 pushes the first pressure block 16 obliquely through the pushing inclined surface A, causing the first pressure block 16 to move away from the installation space. The pressure spring 17 is horizontal. The compression spring 17 is configured such that one end is connected to the outer end face of the first pressure block 16, and the other end is connected to the inner wall of the second through groove C. In its natural state, the elastic force of the compression spring 17 pushes the first pressure block 16 toward the installation space. When the first slide block 13 drives the inclined push rod 15 to move linearly toward the installation space, the first pressure block 16 is pushed outward by the inclined surface A to overcome the elastic force of the compression spring 17. At the same time, the slide rod 19 drives the second slide block 110 to move away from the installation space. The second pressure block 111 is set on the second slide block 110. The second pressure block 111 and the guide bracket 18 clamp and fix the relay assembly 0 from the open surfaces on the other two sides of the installation space.

[0071] To address the problem of clamping and positioning relay housings during installation, this invention designs a carrier. The carrier uses a horizontally positioned carrier base as its supporting structure. The carrier base is equipped with an L-shaped limiting block, which forms an installation space with openings on both sides above the carrier base for placing the relay housing. The two inner sidewalls of the limiting block serve as positioning reference surfaces. The two open sides of the installation space are respectively equipped with a first pressing block and a second pressing block, which are used to clamp and position the relay housing placed in the installation space to ensure the positional stability of the relay housing during installation. The unique feature is that the first and second pressure blocks of this invention have adaptive flexible clamping and fixing, and realize the linkage synchronous opening and closing function of a single power drive; specifically, this invention has two sliding rods inserted parallel and spaced apart in the carrier seat, the two sliding rods are slidably inserted in the carrier seat, one end of the two sliding rods is vertically provided with a first sliding seat, and the other end is vertically provided with a second sliding seat, thereby forming an integral rectangular frame structure, and the rectangular frame structure slides freely in the carrier seat; the second pressure block is set on the second sliding seat and is located at one side opening of the installation space; the first sliding seat is vertically provided with an inclined push rod, the inclined push rod extends to the other side opening of the installation space, and its outer side is provided with a pushing slope; the inclined push rod is inserted into the first pressure block of the U-shaped structure. Inside the block, a guide seat is provided on the top of the first pressing block. The first pressing block slides freely in the second through groove below the guide seat and is connected to the inner wall of the second through groove through a compression spring. In its natural state, the elastic force of the compression spring tends to drive the first pressing block to move towards the installation space so as to flexibly clamp and fix the relay housing in the installation space. At the same time, a slide spring is sleeved on the slide rod between the first slide and the carrier seat. In its natural state, the elastic force of the slide spring tends to push the first slide outward. At this time, the first slide drives the inclined push rod to move outward, so that the first pressing block clamps and fixes the relay housing under the action of the compression spring. Simultaneously, the second slide drives the second pressing block to move towards the installation space, realizing the linkage and synchronous clamping and fixing of both sides. When an external force is applied to the first slide block and overcomes the elastic force of the slide bar spring to push the first slide block towards the installation space, the first slide block pushes the second slide block and the second pressure block on it away from the installation space through the slide bar, releasing the relay housing; at the same time, the inclined push rod pushes the first pressure block outward through the inclined surface, causing it to move outward in the second through slot, releasing the relay housing. Thus, through single-power drive, the first and second pressure blocks are simultaneously driven open, effectively saving energy while ensuring linkage.

[0072] Example 3: As Figures 16 to 20As shown, the guiding and pushing mechanism 2 of the present invention includes a first pushing bracket 21, a lifting cylinder 22, a lifting slide 23, a pushing assembly, and a guiding assembly. The first pushing bracket 21 is vertically disposed on the side of the carrier 1. The lifting cylinder 22 is vertically disposed on the side wall of the first pushing bracket 21 and outputs power in the vertical direction. The lifting slide 23 is slidably connected in the vertical direction to the side wall of the first pushing bracket 21 and connected to the output end of the lifting cylinder 22, and is driven to move up and down by the lifting cylinder 22. The guiding assembly is disposed at the bottom of the lifting slide 23 and extends downwards. The guiding assembly descends with the lifting slide 23 to insert into the carrier 1 and to pick up the relay frame 02 to be assembled, and to guide and limit the installation of the relay frame 02. The pushing assembly is disposed on the lifting slide 23 and located above the guiding assembly. The pushing assembly outputs power in the vertical direction to insert into the guiding assembly and embed the relay frame 02 into the relay housing 01.

[0073] The feeding assembly includes a first feeding cylinder 24, a feeding seat 25, a push rod 26, and a feeding guide seat 27. The first feeding cylinder 24 is mounted on the lifting slide 23 with its output end facing upward. The feeding seat 25 is connected to the output end of the first feeding cylinder 24 and extends horizontally outward. The push rod 26 is connected to the bottom of the feeding seat 25 and extends vertically downward to be inserted into the guide assembly.

[0074] The guiding assembly includes a pusher guide seat 27, an insertion guide seat 28, a guide block support 29, a guide block 210, and a guide frame 211. The insertion guide seat 28 is horizontally mounted on the side wall of the lifting slide 23. The top of the insertion guide seat 28 has an inwardly recessed mounting groove G, and the side of the mounting groove G also has a vertically penetrating pusher guide groove F. The relay frame 02 to be assembled is placed into the pusher guide groove F via the material handling mechanism 4. The pusher guide seat 27 is located within the mounting groove G, and a vertically penetrating guide hole is opened on the pusher guide seat 27 corresponding to the push rod 26. The push rod 26 slides freely through the guide hole, is guided and limited by the guide hole, and then inserts downwards into the pusher guide groove F to push the relay in the pusher guide groove F downwards. The device frame 02 is embedded in the relay housing 01. The guide frame 211 is located below the insertion guide seat 28. The guide frame 211 is a frame structure with a guide groove H in the middle. The guide frame 211 is inserted into the relay housing 01. The relay frame 02 is inserted into the relay housing 01 along the side wall of the guide frame 211. The moving terminal 04 is inserted horizontally through the guide groove H into the relay frame 02 and the relay housing 01, and is guided and limited by the guide groove H. The guide block support 29 is located on the side of the insertion guide seat 28. The guide block 210 is connected to the lower part of the guide block support 29. The guide block 210 extends to the outside of the guide groove H. Its inner side wall is provided with a transition slope for guiding and limiting when the moving terminal 04 is inserted into the guide groove H.

[0075] To address the issues of relay housing installation and positional misalignment when the moving terminal is embedded in the relay housing, this invention designs a guiding and pushing mechanism. The guiding and pushing mechanism is located on the side of the carrier and extends above it. A vertically positioned pushing bracket serves as the supporting structure. A lifting cylinder is located on one side of the pushing bracket, with its output end facing downwards. The lifting cylinder drives a lifting slide connected to it to move up and down. The bottom of the lifting slide is horizontally connected to a guide socket, and the top of the guide socket is equipped with a pushing guide seat. A pushing cylinder is located on the side wall of the lifting slide, with its output end facing upwards and horizontally connected to a pushing seat. A push rod is vertically connected to the bottom of the pushing seat. During assembly, the lifting cylinder first drives the lifting seat to insert the insertion guide seat into the relay housing. The insertion guide seat has a pushing guide that runs vertically upwards and downwards. The groove forms a vertical material guiding space, while the guide holes on the insertion guide form a horizontal material guiding space. The insertion guide, which is inserted into the relay housing, simultaneously forms both vertical and horizontal material guiding spaces. The vertical material guiding space is used for guiding and limiting when assembling the relay frame, ensuring the positional accuracy of the relay frame when inserted into the relay housing. The horizontal material guiding space is used for guiding and limiting when assembling the moving terminal, ensuring both the positional stability of the relay frame and the precise insertion of the moving terminal into the relay frame. After the relay frame to be assembled is placed into the push guide groove from above, the push cylinder drives the push rod to move downward. The push rod passes through the push guide and inserts downward into the push guide groove, pushing the relay frame in the push guide groove into the relay housing. During the downward pushing process, the push rod is guided and limited by the guide holes on the push guide.

[0076] Example 4: Figures 21 to 25 As shown, the rotary feeding mechanism 3 of the present invention includes a horizontal support 31, a transverse bearing assembly, a rotary drive assembly, and a rotary head 38. The horizontal support 31 is horizontally disposed on the side of the carrier 1. The transverse bearing assembly is disposed on the horizontal support 31 and outputs power in a straight line. The rotary drive assembly is disposed on the transverse bearing assembly and outputs linear power horizontally, converting the linear power into rotational power. The rotary head 38 is connected to the rotary drive assembly and rotates under the drive of the rotary drive assembly. The rotary head 38 picks up the relay frame 02 to be assembled, clamps and fixes the relay frame 02, and then drives it to rotate.

[0077] The transverse support assembly includes a transverse cylinder 32, a transverse slide 33, and a transverse support 34. The transverse cylinder 32 is horizontally mounted on a horizontal support 31 and outputs power in a straight line. The transverse slide 33 is slidably mounted on the horizontal support 31 and connected to the output end of the transverse cylinder 32. It moves linearly driven by the transverse cylinder 32 and extends upward in a vertical direction. The transverse support 34 is horizontally mounted on one side of the transverse slide 33.

[0078] The rotary drive assembly includes a rotary drive cylinder 35, a drive rack 36, a rotary shaft 37, drive teeth, and a limiting post 39. The rotary drive cylinder 35 is horizontally mounted on a transverse support 34. The drive rack 36 is horizontally slidably mounted on the transverse support 34 and connected to the output end of the rotary drive cylinder 35. The rotary shaft 37 is rotatably inserted into a transverse slide 33 and located above the transverse support 34, with both ends extending to opposite sides of the transverse slide 33. The drive teeth are sleeved on one end of the rotary shaft 37 and mesh with the drive rack 36 below. When the drive rack 36 moves linearly, it drives the rotary shaft 37 to rotate via the drive teeth. A rotary head 38 is connected to the other end of the rotary shaft 37 and rotates with it. The limiting post 39 is connected to the rotary head 38 and, during its rotation, abuts against a limiting seat on the transverse slide 33 to block and limit the rotary head 38.

[0079] The rotating head 38 includes a rotating seat 381, a support shaft 383, a support base 384, a clamping cylinder 385, a rotating pressure seat 386, rotating springs 387, and a rotating pressure plate 388. The rotating seat 381 has an inwardly recessed rotating mounting groove 382 on one side wall for fitting a connecting rotating shaft 37. The top of the rotating seat 381 has an inwardly recessed material groove I, with an opening at the top of the material groove I and on the other side of the rotating seat 381 for vertically inserting a relay frame 02. The support shaft 383 is horizontally inserted into the material groove I. The support base 384 is horizontally positioned on the other side wall of the rotating seat 381, below the material groove I. The rotating pressure seat 386 is rotatably fitted onto the support shaft 383, and at least two rotating springs 387 are connected to the lower part of the rotating pressure seat 386. One end of each rotating spring 387 is connected to a rotating cylinder. The rotating pressure seat 386 is located on the inner wall of the rotating pressure seat 386, with one end connected to the wall of the material trough I. In its natural state, the spring force of the rotating spring 387 pushes the lower part of the rotating pressure seat 386 outward, causing the upper part of the rotating pressure seat 386 to move towards the material trough I. The pressing cylinder 385 is mounted on the support seat 384 and located on the outside of the rotating pressure seat 386. The output end of the pressing cylinder 385 is connected to the lower part of the outer side of the rotating pressure seat 386. The pressing cylinder 385 outputs power to push the rotating pressure seat 386 to overcome the spring force of the rotating spring 387 and move towards the material trough I. The rotating pressing plate 388 is horizontally mounted on the inner wall of the rotating pressure seat 386 and close to the upper part of the rotating pressure seat 386. The rotating pressing plate 388 moves with the rotating pressure seat 386 and is inserted into the material trough I from the opening on the other side of the material trough I to press the relay frame 02 inside the material trough I.

[0080] To address the issue of automatic feeding of relay frames during assembly, this invention designs a rotary feeding mechanism. This mechanism includes a horizontal support, a transverse support assembly, a rotary drive assembly, and a rotary head. The horizontal support is horizontally positioned on the side of the carrier. The transverse support assembly is mounted on the horizontal support and outputs power vertically to drive the rotary drive assembly and rotary head to move back and forth linearly between the receiving position and the picking position. The transverse support assembly drives the rotary drive assembly and rotary head to the receiving position to horizontally receive the relay frames transported by the external loading mechanism, and simultaneously moves the received relay frames to the picking position for the picking mechanism to pick them up. During the transfer of the relay frame, the rotary drive assembly drives the rotating head to rotate the relay frame from a horizontal direction to a vertical direction, so that the material handling mechanism can vertically remove the relay frame. The key feature is that the rotary drive assembly of this invention uses a rotary drive cylinder horizontally mounted on a transverse support as its power source. The rotary drive cylinder pushes a drive rack to move back and forth linearly on the transverse support. The drive rack meshes with drive teeth fitted on a rotating shaft rotatably inserted into a transverse slide above it. Through this toothed connection, the linear motion of the drive rack is converted into the rotational motion of the drive teeth. When the drive teeth drive the rotating shaft to rotate, the rotating shaft drives the rotating head connected to its end to rotate, so as to remove the relay frame vertically. The relay frame inside rotates from a horizontal to a vertical direction; furthermore, the rotating head of the present invention is vertically arranged, and a rotating seat connected to the rotating shaft serves as a bearing structure. A material trough is provided on the top of the rotating seat, with openings on the top and other sides. The top opening is used to pick up and place the relay frame, and the side opening is used to support or fix the relay frame inside the material trough. Specifically, a support seat is horizontally provided on the other side wall of the rotating seat, located below the material trough; a support shaft is horizontally provided inside the material trough, and a rotating pressure seat is rotatably fitted on the support shaft. The bottom and top of the rotating pressure seat extend to the upper and lower sides of the support shaft, respectively; a clamping cylinder is horizontally provided on the support seat. The output end is connected to the lower side of the outer wall of the rotary pressure seat. When the pressure cylinder outputs power to push the lower part of the rotary pressure seat, it causes the rotary pressure seat to rotate around the support shaft. A rotary spring is provided on the lower inner side of the rotary pressure seat. One end of the rotary spring abuts against the inner wall of the rotary pressure seat, and the other end abuts against the inner wall of the material trough. Under normal conditions, the elastic force of the rotary spring pushes the lower part of the rotary pressure seat outward, causing the rotary pressure seat to rotate around the support so that the rotary pressure plate set on the upper part of the inner wall of the rotary pressure seat is pressed into the material trough to lift or press the relay frame in the material trough. When it is necessary to remove or put away the relay frame, the pressure spring pushes the lower part of the rotary pressure seat from the outside, causing the rotary pressure plate on the upper part of the rotary pressure seat to be pulled out of the material trough.

[0081] Example 5: Figures 26 to 29As shown, the material handling mechanism 4 of the present invention includes a material handling bracket 41, a material handling crossbeam 42, a material handling transverse cylinder 43, a material handling transverse seat 44, a material handling lifting cylinder 45, and a material handling head 46. The material handling bracket 41 is mounted on the side of the carrier 1; the material handling crossbeam 42 is disposed on the side wall of the material handling bracket 41; the material handling transverse cylinder 43 is horizontally disposed on the side wall of the material handling crossbeam 42; the material handling transverse seat 44 is slidably connected to the side wall of the material handling crossbeam 42 in the horizontal direction and is connected to the output end of the material handling transverse cylinder 43; the material handling lifting cylinder 45 is vertically disposed on the side wall of the material handling transverse seat 44, with its output end facing downwards; the material handling head 46 is slidably connected to the side wall of the material handling transverse seat 44 in the vertical direction and is connected to the output end of the material handling lifting cylinder 45, and is driven to move up and down by the material handling lifting cylinder 45.

[0082] The material receiving head 46 includes a material receiving support plate 461, a material receiving support 462, a material receiving rotary cylinder 463, a material receiving rack 464, a rotating gear 465, a material receiving rotating seat 466, a material clamping cylinder 467, and a material clamping block 468. The material receiving support plate 461 is connected to the output end of the material receiving lifting cylinder 45. The material receiving support 462 is disposed on the side wall of the material receiving support plate 461, and a rotating shaft is rotatably inserted vertically inside the material receiving support 462.

[0083] To address the issue of automatic material handling and transfer of relay frames, this invention includes a material handling mechanism. After the material handling mechanism removes the relay frame, which has been rotated to a vertical position, from the rotary feeding mechanism, it maintains the vertical position and inserts it into the pusher groove of the guide mechanism to embed the relay frame into the relay housing. Specifically, the material handling mechanism uses a vertically positioned material handling bracket as its supporting structure. A horizontally positioned material handling transverse cylinder on the material handling bracket provides horizontal power to transfer the relay frame between the rotary feeding mechanism and the carrier. The material handling transverse cylinder drives the material handling transverse seat to move horizontally, thereby driving a material handling lifting cylinder on its side wall. The material handling lifting cylinder provides vertical power to drive the material handling head to move up and down, thus feeding the relay frame downward into the pusher groove. Furthermore, due to the difference between the material picking angle and the installation angle, the material picking head of this invention has the function of adjusting the angle in the horizontal plane. The material picking head uses a material picking support plate as a load-bearing structure. A material picking support is provided on the side wall of the material picking support plate. A rotating shaft is vertically rotatable inside the material picking support. A rotating gear is sleeved on the rotating shaft inside the material picking support. A horizontal groove is provided on the outside of the rotating shaft. A material picking rack is slidably provided in the horizontal groove. The material picking rack is meshed with the rotating gear. When the material picking rotary cylinder drives the material picking rack to move horizontally in the horizontal groove, the material picking rack drives the rotating gear to rotate the rotating shaft. The mechanism involves a rotating shaft and a rotating gear. The linear motion of the rotary cylinder is converted into rotational power in the horizontal plane through the meshing connection between the drive rack and the rotating gear, thereby achieving rotational drive of the rotating shaft. The rotating shaft extends to the bottom of the material-picking support, where a material-picking rotating seat is located. A clamping cylinder is connected to the bottom of the material-picking rotating seat. The clamping cylinder drives two clamping blocks connected to its lower output end to move relative to or towards each other, which is used to remove the vertically set relay frame from the rotary feeding mechanism. At the same time, the rotating shaft drives the clamping cylinder and the clamped relay frame to rotate in the horizontal plane, which is used to adjust the angle of the relay frame.

[0084] Example 6: As Figures 30 to 31As shown, the feeding mechanism 5 of the present invention includes a second feeding bracket 51, a feeding lifting cylinder 52, a feeding lifting seat 53, a feeding horizontal seat 54, a spring support rod 55, a feeding spring 56, a feeding slide 57, a second feeding cylinder 58, and a feeding block 59. The second feeding bracket 51 is mounted on the side of the carrier 1; the feeding lifting cylinder 52 is disposed on the side wall of the second feeding bracket 51, with its output end facing upwards; the feeding lifting seat 53 is slidably disposed vertically on the side wall of the feeding lifting cylinder 52 and connected to the output end of the feeding lifting cylinder 52; the feeding horizontal seat 54 is horizontally disposed on the top of the feeding lifting seat 53; and the feeding slide 57 is slidably disposed horizontally on the feeding horizontal seat 54. The spring support rod 55 is vertically mounted on the side wall of the pusher horizontal seat 54; one end of the pusher spring 56 is connected to the spring support rod 55, and the other end is connected to the pusher slide 57. In its natural state, the elastic force of the pusher spring 56 pulls the pusher slide 57 to move towards the carrier 1, which is used to push the moving terminal 04 into the relay housing 01; the second pusher cylinder 58 is mounted on the pusher slide 57 and outputs power in a direction perpendicular to the pusher spring 56; one end of the pusher block 59 is slidably mounted on the pusher slide 57 and connected to the output end of the second pusher cylinder 58, and the other end of the pusher block 57 extends outward and forms a downward extending strip-shaped pressure bar. The strip-shaped pressure bar abuts against the moving terminal 04 and is adjusted in relative position by the second pusher cylinder 58.

[0085] To address the issue of automatic insertion of moving terminals, this invention incorporates a pushing mechanism. This mechanism is located on the side of the carrier and uses a vertically mounted pushing bracket as its support structure. A pushing lifting cylinder is located on one side of the pushing bracket to provide vertical power. The pushing lifting cylinder drives the pushing lifting seat to move up and down, adjusting the vertical height. A pushing horizontal seat is mounted on the pushing horizontal seat, and a pushing slide is slidably mounted on the pushing horizontal seat. The pushing slide is connected to the pushing horizontal seat via a pushing spring. In its natural state, the spring force maintains the pushing slide in one direction. The side-pulling tendency facilitates maintaining flexible contact with the moving terminal during the pushing or correction process, achieving elastic buffering. A pushing cylinder is provided on the pushing slide perpendicular to its sliding direction. The pushing cylinder drives the pushing block to output linear power in a direction perpendicular to the movement of the pushing slide. During pushing, the elastic force of the pushing spring drives the pushing slide to move the pushing cylinder and the pushing block above it closer to the moving terminal placed on the relay housing. The elastic force presses the moving terminal into the relay frame, while the pushing cylinder drives the pushing block to slide linearly on the side of the moving terminal, pushing the moving terminal into the relay frame in a line contact manner.

[0086] Example 7: As Figures 31 to 34As shown, in another embodiment, a pusher head can also be provided on the pusher slide 57 of the present invention to replace the second pusher cylinder 58 and the pusher block 59. The pusher head includes a second pusher cylinder 510, a second pusher slide 511, a second pusher block 512, and a pusher guide block 514. The second pusher cylinder 510 can be horizontally arranged on the pusher slide 57 and outputs linear power in a direction perpendicular to the moving terminal 04. The second pusher slide 511 is connected to the output end of the second pusher cylinder 510, and the second pusher block 512 is arranged on the second pusher slide 57. On the 11th, and extending towards the moving terminal 04, the second pusher block 512 is provided with an inwardly recessed pusher groove 513 on the side near the moving terminal 04, and the pusher guide block 514 is horizontally arranged above the pusher groove 513 and extends horizontally towards the moving terminal 04; during the pusher process, the pusher groove 513 is nested on the moving terminal 04 from the outside and guided and positioned by the pusher guide block 514 above to ensure the accuracy of its relative position with the moving terminal 04, and the second pusher cylinder 510 drives the second pusher block 512 to push the moving terminal 04 into the relay frame.
