After the two iron frames are symmetrically assembled to form a rectangular frame structure, it is also necessary to vertically insert assembly magnetic blocks at both ends of the rectangular frame structure composed of the iron frames; then, the relay core body is vertically inserted into the rectangular frame with the magnetic blocks installed to form a semi-finished relay; then, the relay semi-finished product is assembled as a whole into the relay bottom shell, and the bottom plate at the bottom of the core body is riveted and fixed to the iron frame; finally, the relay semi-finished product is assembled as a whole into the relay bottom shell, and the top cover is assembled to form an integrated relay.

[0017] An assembling machine comprises a relay and an automatic assembly mechanism of an iron frame thereof.

[0018] The beneficial effects of the present invention are: In view of the defects and shortcomings of the prior art, the present invention independently develops and designs a relay and its iron frame automatic assembly mechanism and its assembly machine with flexible material shifting and inclined top limiting functions to realize automatic material replacement in a load-bearing cycle, and adopts embedded side suction to realize adsorption-type material taking and placing of the bottom shell and the U-shaped iron frame, thereby effectively avoiding motion interference during assembly while realizing material taking and placing, and at the same time having movable assembly limiting material guiding, elastic material pressing and post-assembly pressing functions, which effectively improve the assembly accuracy and position accuracy of the relay and its iron frame automatic assembly mechanism and its assembly machine.

[0019] The present invention aims to provide a device which is arranged in a relay assembly machine and is used to realize automatic high-precision assembly of components such as a bottom shell and an iron frame of a relay, so as to improve the efficiency and precision of the automatic assembly of the relay.

[0020] Specifically, in order to ensure the material carrying capacity during the automated assembly of relays and maintain the continuity of assembly, the assembly platform used for bearing support during the assembly process of the present invention adopts an automatic cycle material replacement method, and the upper horizontal support platform of the platform bracket of the assembly platform of the upper and lower structures is the bearing platform, on which two reference limit strips arranged in parallel and at intervals form a limit space for placing multiple groups of relay carriers, and the relay carrier is provided with multiple bearing slots so as to simultaneously carry and assemble multiple relays; the horizontal support platform is provided with a pushing slide and a limit slide that pass through the upper and lower parts, and a flexible pushing component arranged below the horizontal support platform passes through the pushing slide to move the relay carrier The horizontal support is cyclically shifted to move the vacant relay carrier to the bottom of the assembly mechanism; at the same time, the limit assembly arranged under the horizontal support passes through the limit slide groove to resist the relay carrier to maintain its position stability during the assembly process; the special feature is that after the flexible pushing assembly pushes a group of relay carriers, it needs to return to the starting position and then push the next group of relay carriers again. During the return process, if the state of extending the pushing slide groove upward is maintained, there will be motion interference with another group of relay carriers. In order to solve this technical problem, one end of the push block of the flexible pushing assembly of the present invention is inserted into the U-shaped mounting groove of the pushing seat. The rotating shaft is rotatably connected, and the other end of the push block is an inclined pressure surface extending obliquely upward, which is used to play a transition role in the process of contacting the bottom of the relay carrier during the return process after pushing; at the same time, a push spring is vertically arranged at the lower part of the other end of the push block. During the return process of the push block, the relay carrier presses the push spring downward through the inclined pressure surface until the push block is pressed down to the bottom of the relay carrier, and then returns to the starting pushing position to push the next group of relays. The motion interference problem in the process of pushing the material back is effectively solved by the inclined pressure surface transition of the push block and the rotatable installation method of the other end. At the same time, the upward elastic force of the push spring causes the push block to pass through another group of relays. When the electrical appliance carrier returns to the starting position, the pushing block is lifted up again to the top of the pushing chute so as to push the next group of relays. In addition, when the limit assembly of the present invention releases the relay carrier after the limit is completed, there is also a motion interference problem. To solve this problem, the limit assembly of the present invention adopts an inclined upward power output method, that is, when limiting is required, the limit cylinder of the limit assembly outputs power obliquely upward to drive the oblique limit block to pass through the limit chute to hold the fixed relay carrier. When the material on the relay carrier is assembled, the limit cylinder drives the oblique limit block obliquely downward to release the relay carrier and retract downward to below the limit chute.

[0021] In addition, for the assembly and taking and placing of the relay bottom shell and the U-shaped iron frame, the assembly head of the assembly mechanism of the present invention adopts an embedded side suction method to complete the taking and placing of the relay bottom shell and the iron frame. This internal side suction method effectively utilizes the shape structure of the relay bottom shell and the iron frame, and can avoid deformation damage to the relay bottom shell during external clamping; and because the iron frame is a rectangular frame structure formed by symmetrically splicing two U-shaped frame bodies, it is very easy to cause relative position offset between the two U-shaped frame bodies when taking and placing materials by external clamping, and the position accuracy of the iron frame cannot be guaranteed during taking and placing materials; and the internal side suction fixing method of the present invention realizes independent adsorption and fixation of the two U-shaped frame bodies during taking and placing materials, and can effectively maintain the stability of the joint position of the two U-shaped frame bodies; in addition, during the assembly process, after the relay housing is placed on the relay carrier, the iron frame of the rectangular frame structure needs to be inserted into the relay housing from top to bottom. The gap between the inner wall of the device housing and the outer wall of the iron frame is small, and the external clamping method is adopted, which will inevitably cause movement interference with the relay bottom shell during the assembly of the iron frame; therefore, the internal side suction fixing method of the present invention can effectively avoid movement interference with the relay bottom shell during the insertion of the iron frame; specifically, the material picking head of the present invention uses a material picking seat as an execution structure, and a plurality of mounting holes are opened on the side wall of the material picking seat, and suction blocks are horizontally inserted into the plurality of mounting holes, respectively. The suction holes can be made of magnet material so as to adsorb the metal relay bottom shell and the iron frame during the material picking process. After the material picking seat extends into the inside of the relay bottom shell and the iron frame during the material picking process, the suction block is used to fix the inner wall of the relay bottom shell or the iron frame from the inside to achieve adsorption and fixation; in addition, the material picking seat is connected and supported by a connecting column and a buffer spring, so that it has flexible buffering capacity in the vertical direction to avoid excessive pressure in the vertical direction during the material picking process, resulting in product damage.

[0022] In addition, for the assembly of relays, the present invention also designs a guiding and pressing mechanism to assist in guiding, limiting and pressing during the assembly process, so as to improve the assembly accuracy and effectively avoid the problem that the material picking head leaves the relay bottom shell or iron frame upward after the material is discharged, and the relay bottom shell or iron frame is pulled up due to its adsorption force. Specifically, the guiding and pressing mechanism is integrally erected above the assembly platform, including a pressing bracket as a bearing structure, and a pressing cylinder vertically downwardly arranged on the pressing bracket serves as a driving force in the vertical direction during pressing, so as to drive the pressing lifting seat below to press horizontally downward toward the relay bottom shell on the assembly platform and the iron frame inserted therein after assembly is completed, so as to level the surface flatness of the assembled relay bottom shell and the iron frame; in addition, after the relay bottom shell is assembled, the pressing guide component of the guiding and pressing mechanism is used to press the relay bottom shell horizontally from above the relay bottom shell, so as to prevent the relay bottom shell from being lifted up from the relay carrier due to its suction force when the material picking head is upwardly separated from the relay bottom shell; at the same time, the pressing guide component can also play a guiding and limiting role in the process of inserting the iron frame, and press the inserted iron frame downward by elastic pressing, so as to prevent the iron frame from being lifted up from the relay bottom shell due to its suction force when the material picking head moves upward after inserting the iron frame. Specifically, the press guide assembly outputs power in the vertical direction with the lifting cylinder to drive the press frame connected horizontally below it to move up and down. The function of the press frame is to use the side of the press frame to press and fix the relay bottom shell from the top after the relay bottom shell is assembled. At the same time, the middle part of the press frame is provided with a guide groove that runs through the top and bottom to facilitate the material picking head to drive the iron frame to pass through and insert the iron frame into the assembled relay bottom shell. Furthermore, an opening and closing cylinder is horizontally provided on the press frame, and the output end of the opening and closing cylinder drives the two opening and closing frames on the press frame respectively. When the relay bottom shell is inserted, the two opening and closing frames are opened or closed horizontally. When the relay bottom shell is inserted, the two opening and closing frames are opened outward. After the relay bottom shell is inserted, the two opening and closing frames are closed to each other to form a rectangular frame above the guide groove. In addition, the two opening and closing frames are provided with guide pieces extending obliquely downward. When the iron frame is inserted, the guide pieces arranged obliquely downward play a transition role by obliquely contacting the material taking head, thereby avoiding motion interference with the material taking head. At the same time, the elastic guide pieces elastically press the iron frame downward after the iron frame is inserted, thereby avoiding the iron frame being brought out when the material taking head is pulled out upward.

[0050] like Figures 1 to 8 As shown, the present invention proposes a relay and an automatic iron frame assembly mechanism thereof, which are arranged in a relay automatic assembly machine and are used for automatically assembling relays, including an assembly platform 1, an assembly mechanism 2 and a guide pressing mechanism 3, wherein the assembly platform 1 is arranged horizontally, and at least two assembly stations are arranged on the assembly platform 1, at least two relay carriers 15 are placed on the at least two assembly stations, and at least two relay components 0 are placed on the relay carrier 15; the assembly platform 1 includes a flexible pushing component 12 and a limiting component 13, wherein the flexible pushing component 12 is arranged on at least two It is below the assembly station and outputs power in a linear direction to drive the relay carrier 15 to move between different assembly stations; the limiting component 13 is arranged below at least two assembly stations to limit the relay carrier 15 at the assembly station; the assembly mechanism 2 is set above the assembly platform 1 to transport and assemble the relay assembly 0; the guiding and pressing mechanism 3 is set above the assembly platform 1 to pre-press the bottom shell 01 of the relay assembly 0 during the assembly process, and guide and flexibly press down the iron frame 03 placed in the bottom shell 01 to prevent the iron frame 03 from moving upward with the assembly mechanism 2.

[0051] The present invention designs a relay and its iron frame automatic assembly mechanism and its assembly machine with flexible material selection and inclined top limit functions, realizing automatic material replacement in load-bearing cycle, using embedded side suction to realize adsorption-type material picking and placing of the bottom shell and the U-shaped iron frame, realizing material picking and placing while effectively avoiding motion interference during assembly, and having movable assembly limit material guiding and elastic material pressing and post-assembly material pressing functions, effectively improving assembly accuracy and position accuracy. The present invention aims to provide a relay assembly machine, which is used to realize automatic high-precision assembly of components such as the bottom shell and iron frame of the relay, so as to improve the efficiency and accuracy of automatic assembly of the relay.Specifically, in order to ensure the material carrying capacity during the automated assembly of relays and maintain the continuity of assembly, the assembly platform used for bearing support during the assembly process of the present invention adopts an automatic cycle material replacement method, and the upper horizontal support platform of the platform bracket of the assembly platform of the upper and lower structures is the bearing platform, on which two reference limit strips arranged in parallel and at intervals form a limit space for placing multiple groups of relay carriers, and the relay carrier is provided with multiple bearing slots so as to simultaneously carry and assemble multiple relays; the horizontal support platform is provided with a pushing slide and a limit slide that pass through the upper and lower parts, and a flexible pushing component arranged below the horizontal support platform passes through the pushing slide to move the relay carrier The horizontal support is cyclically shifted to move the vacant relay carrier to the bottom of the assembly mechanism; at the same time, the limit assembly arranged under the horizontal support passes through the limit slide groove to resist the relay carrier to maintain its position stability during the assembly process; the special feature is that after the flexible pushing assembly pushes a group of relay carriers, it needs to return to the starting position and then push the next group of relay carriers again. During the return process, if the state of extending the pushing slide groove upward is maintained, there will be motion interference with another group of relay carriers. In order to solve this technical problem, one end of the push block of the flexible pushing assembly of the present invention is inserted into the U-shaped mounting groove of the pushing seat. The rotating shaft is rotatably connected, and the other end of the push block is an inclined pressure surface extending obliquely upward, which is used to play a transition role in the process of contacting the bottom of the relay carrier during the return process after pushing; at the same time, a push spring is vertically arranged at the lower part of the other end of the push block. During the return process of the push block, the relay carrier presses the push spring downward through the inclined pressure surface until the push block is pressed down to the bottom of the relay carrier, and then returns to the starting pushing position to push the next group of relays. The motion interference problem in the process of pushing the material back is effectively solved by the inclined pressure surface transition of the push block and the rotatable installation method of the other end. At the same time, the upward elastic force of the push spring causes the push block to pass through another group of relays. When the electrical appliance carrier returns to the starting position, the pushing block is lifted up again to the top of the pushing chute so as to push the next group of relays. In addition, when the limit assembly of the present invention releases the relay carrier after the limit is completed, there is also a motion interference problem. To solve this problem, the limit assembly of the present invention adopts an inclined upward power output method, that is, when limiting is required, the limit cylinder of the limit assembly outputs power obliquely upward to drive the oblique limit block to pass through the limit chute to hold the fixed relay carrier. When the material on the relay carrier is assembled, the limit cylinder drives the oblique limit block obliquely downward to release the relay carrier and retract downward to below the limit chute.

[0060] like Figure 15 to Figure 16 As shown in the figure, as an embodiment of the present invention, the assembly head 29 of the present invention includes a connecting column 291, a buffer spring 292, a material picking seat 293, a suction block 294 and a spring seat 295, wherein the connecting column 291 is vertically inserted on the rotating seat 28 and extends to the bottom of the rotating seat 28; the material picking seat 293 is arranged at the lower part of the connecting column 291, and a vertically extending mounting socket D is opened in the material picking seat 293; the connecting column 291 is inserted in the mounting socket D, and It is movable in the vertical direction; the buffer spring 292 is sleeved on the connecting column 291, the lower end of the buffer spring 292 abuts against the material picking seat 293, and the upper end passes through the rotating seat 28 and abuts against the spring seat 295 provided on the rotating seat 28; at least two mounting holes are provided on the side of the material picking seat 293; the suction block 294 includes at least two blocks, and at least two suction blocks 294 are respectively inserted into at least two mounting holes, for adsorbing and fixing the inner side wall of the iron frame 03 of the relay assembly 0 from the side.

[0061] The present invention is aimed at the assembly and taking and placing of the relay bottom shell and the iron frame of the U-shaped structure. The assembly head of the assembly mechanism of the present invention adopts an embedded side suction method to complete the taking and placing of the relay bottom shell and the iron frame. This internal side suction method effectively utilizes the shape structure of the relay bottom shell and the iron frame, and can avoid deformation damage to the relay bottom shell during external clamping; and because the iron frame is a rectangular frame structure formed by symmetrically splicing two U-shaped structure frames, it is very easy to cause relative position offset between the two U-shaped structure frames when taking and placing materials by external clamping, and the position accuracy of the iron frame cannot be guaranteed during taking and placing materials; and the internal side suction fixing method of the present invention realizes independent adsorption and fixation of the two U-shaped structure frames during taking and placing materials, and can effectively maintain the stability of the joint position of the two U-shaped structure frames; in addition, during the assembly process, after the relay housing is placed on the relay carrier, the iron frame of the rectangular frame structure needs to be inserted into the relay housing from top to bottom. The gap between the inner wall of the device housing and the outer wall of the iron frame is small, and the external clamping method is adopted, which will inevitably cause movement interference with the relay bottom shell during the assembly of the iron frame; therefore, the internal side suction fixing method of the present invention can effectively avoid movement interference with the relay bottom shell during the insertion of the iron frame; specifically, the material picking head of the present invention uses a material picking seat as an execution structure, and a plurality of mounting holes are opened on the side wall of the material picking seat, and suction blocks are horizontally inserted into the plurality of mounting holes, respectively. The suction holes can be made of magnet material so as to adsorb the metal relay bottom shell and the iron frame during the material picking process. After the material picking seat extends into the inside of the relay bottom shell and the iron frame during the material picking process, the suction block is used to fix the inner wall of the relay bottom shell or the iron frame from the inside to achieve adsorption and fixation; in addition, the material picking seat is connected and supported by a connecting column and a buffer spring, so that it has flexible buffering capacity in the vertical direction to avoid excessive pressure in the vertical direction during the material picking process, resulting in product damage.

[0063] like Figure 20 to Figure 23As shown, as an embodiment of the present invention, the material pressing guide assembly 34 of the present invention includes a material pressing connection seat 341, a lifting cylinder 342, a material pressing frame 343, an opening and closing cylinder 344, an opening and closing frame 345 and a material guiding piece 346, wherein the material pressing connection seat 341 is connected to the top plate and extends horizontally outward; the lifting cylinder 342 is vertically connected below the material pressing connection seat 341, and the output end is set downward; the material pressing frame 343 is connected to the output end of the lifting cylinder 342 and extends horizontally outward, and the material pressing frame 343 is close to one side of the lifting cylinder 342 It is a horizontal supporting surface for placing the opening and closing cylinder 344, and a guide groove E which passes through from top to bottom is provided on the other side of the pressing frame 343; the output end of the opening and closing cylinder 344 is arranged upward; the opening and closing frame 345 includes two, and the two opening and closing frames 345 are respectively connected to the output ends of the opening and closing cylinder 344, and are driven by the opening and closing cylinder 344 to approach or move away from each other above the guide groove E; the guide sheet 346 includes two sheets, and the two guide sheets 346 are respectively arranged on the two opening and closing frames 345, and extend obliquely downward into the guide groove E; the guide sheet 346 is an elastic sheet.

[0064] For the assembly of relays, the present invention designs a guiding and pressing mechanism for assisting in guiding, limiting and pressing during the assembly process, so as to improve the assembly accuracy and effectively avoid the problem that the material picking head leaves the relay bottom shell or iron frame upward after the material is discharged, and the relay bottom shell or iron frame is pulled up due to its adsorption force. Specifically, the guiding and pressing mechanism is integrally erected above the assembly platform, including a pressing bracket as a bearing structure, and a pressing cylinder vertically downwardly arranged on the pressing bracket serves as a driving force in the vertical direction during pressing, so as to drive the pressing lifting seat below to press horizontally downward toward the relay bottom shell on the assembly platform and the iron frame inserted therein after assembly is completed, so as to level the surface flatness of the assembled relay bottom shell and the iron frame; in addition, after the relay bottom shell is assembled, the pressing guide component of the guiding and pressing mechanism is used to press the relay bottom shell horizontally from above the relay bottom shell, so as to prevent the relay bottom shell from being lifted up from the relay carrier due to its suction force when the material picking head is upwardly separated from the relay bottom shell; at the same time, the pressing guide component can also play a guiding and limiting role in the process of inserting the iron frame, and press the inserted iron frame downward by elastic pressing, so as to prevent the iron frame from being lifted up from the relay bottom shell due to its suction force when the material picking head moves upward after inserting the iron frame. Specifically, the press guide assembly outputs power in the vertical direction with the lifting cylinder to drive the press frame connected horizontally below it to move up and down. The function of the press frame is to use the side of the press frame to press and fix the relay bottom shell from the top after the relay bottom shell is assembled. At the same time, the middle part of the press frame is provided with a guide groove that runs through the top and bottom to facilitate the material picking head to drive the iron frame to pass through and insert the iron frame into the assembled relay bottom shell. Furthermore, an opening and closing cylinder is horizontally provided on the press frame, and the output end of the opening and closing cylinder drives the two opening and closing frames on the press frame respectively. When the relay bottom shell is inserted, the two opening and closing frames are opened or closed horizontally. When the relay bottom shell is inserted, the two opening and closing frames are opened outward. After the relay bottom shell is inserted, the two opening and closing frames are closed to each other to form a rectangular frame above the guide groove. In addition, the two opening and closing frames are provided with guide pieces extending obliquely downward. When the iron frame is inserted, the guide pieces arranged obliquely downward play a transition role by obliquely contacting the material taking head, thereby avoiding motion interference with the material taking head. At the same time, the elastic guide pieces elastically press the iron frame downward after the iron frame is inserted, thereby avoiding the iron frame being brought out when the material taking head is pulled out upward.
