[0016] The beneficial effects of the present invention are:
[0017] In view of the defects and shortcomings of the prior art, the present invention independently develops and designs a relay bracket and core body assembly mechanism and an assembly machine thereof that simultaneously realizes the bending and tightening of the four corners of the relay bracket by riveting, and has pre-pressing and leveling before riveting and oblique guide limiting during riveting, which effectively improves the riveting accuracy and simultaneously completes the oblique guide bending of the probe, improves the bending position accuracy of the probe, and effectively improves the assembly efficiency.
[0018] The present invention aims to provide a device applied in the field of automatic assembly of relays, realizing automatic assembly of relay bracket and core body and automatic bending of relay core body probe, and effectively improving the connection assembly and probe bending accuracy while completing the connection assembly and probe bending simultaneously. Specifically, the present invention as a whole uses a bracket with a U-shaped opening structure arranged laterally as a bearing structure, wherein the middle part is an installation space, a driving component is arranged on the top of the bracket, and a riveting component and a probe bending component are connected to the output end of the driving component extending vertically downward, a bearing component is arranged on the support platform of the bracket installation space, and the relay bracket, coil and core body assembly to be assembled are placed on the bearing component; at the same time, oblique sliding limit components are also arranged on both sides of the bearing component.
[0019] Before riveting and bending, first place the relay bracket, coil and core assembly in the bearing groove of the bearing seat of the bearing assembly. At the same time, to ensure stability, the clamping assembly arranged on the rear side of the bearing seat can output power horizontally through the clamping groove opened on the inner wall of the bearing groove to push the relay bracket forward onto the limit block on the front side of the bearing groove.
[0020] Then, a riveting cylinder driving slide arranged at the top of the bracket drives the riveting assembly and the probe bending assembly arranged at the bottom thereof to gradually approach the relay bracket downward. During the descent process, the pressure calibration block of the riveting assembly first contacts the bottom plate of the relay core, and pre-presses the bottom plate of the relay core downward from the left and right sides to achieve flatness calibration of the bottom plate and clamping and fixing before riveting, so as to ensure the surface flatness during subsequent riveting and maintain the position stability of the bottom plate, and avoid positional displacement during riveting and affect the riveting position accuracy; in addition, the pressure calibration block is slidably inserted in the first mounting groove opened on the side of the support in the vertical direction, and a buffer force is provided during pre-stressing by a pressure calibration spring. As the riveting assembly continues to descend, the pressure calibration block slides upward in the first mounting groove and compresses the pressure calibration spring; the flexible installation method of the pressure calibration block enables it to complete the pre-stressing and leveling function without generating motion interference with the descent of the pressure calibration block, and at the same time, the downward elastic pressure generated by the compression of the pressure calibration spring can continuously act downward on the pressure calibration block, so that the pressure calibration block continuously and stably presses the bottom plate of the relay chip during the riveting process.
[0021] After the pre-pressing of the bottom plate of the relay core is completed, as the slide continues to move downward, the rivet block of the rivet assembly contacts the rivet connection part of the bracket, and in the process of continuing to descend, the rivet connection part protruding vertically upward is gradually riveted to the horizontal direction and pressed against the bottom plate of the relay core from above, thereby completing the connection and fixation between the relay bracket and the relay core.
[0022] In addition, during the riveting process of the above-mentioned riveting block, the riveting limit blocks arranged on the left and right sides of the riveting assembly respectively contact the inclined guide limit assemblies arranged on the left and right sides of the bearing seat. During the riveting process, the riveting limit blocks descend synchronously with the slide, and push the limit slider below it to gradually tilt downward on the inclined sliding surface of the limit seat (the riveting limit block and the limit slider are in an active state in the horizontal direction, so the limit slider slides relatively in the horizontal direction relative to the riveting limit block during the sliding process). The reaction force of the limit slider is transmitted to the riveting limit block and the slide, thereby realizing the guide limit of the riveting assembly during the riveting process to ensure the stability of its position state during the descent, and the inclined sliding surface is used as a guiding inclined surface to realize active guidance without affecting the descent of the riveting.
[0023] In addition, during the above-mentioned riveting process, the bending and clamping guide component arranged on the side of the rivet block is synchronously lowered, and the inclined pressure guide block of the bending and clamping guide component first contacts the horizontally placed probe of the relay chip, thereby realizing the pre-pressure fixation of the probe and the pre-pressure leveling of the probe before bending, so as to ensure the position stability of the probe during the subsequent downward bending process; as the riveting assembly continues to descend, the inclined pressure guide block moves upward in the second mounting groove opened on the outer support, and squeezes the pre-pressure spring upward; the pre-pressure spring realizes a buffering effect during the contact process between the inclined pressure guide block and the probe, reducing damage to the probe, and at the same time, the flexible installation method of the inclined pressure guide block in the second mounting groove can avoid the problem of interference with the movement of the rivet block; and the downward rebound force provided by the pre-pressure spring after compression can continuously press down the inclined pressure guide block, so that the inclined pressure guide block can continuously and stably press the unbent part of the probe during the bending process of the probe.
[0024] After the probe pre-pressing is completed, as the slide continues to descend, the probe bending assembly arranged on the side of the riveting assembly approaches the top of the probe, and the bending cylinder of the probe bending assembly outputs downward power to drive the lifting seat to drive the lifting block and the bending roller thereon to move downward. The bending roller gradually descends along the inclined guide arc surface arranged on the side of the above-mentioned inclined pressure guide block and adheres to the probe. During the continued descent, the horizontal probe is gradually bent downward to a vertical state. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Furthermore, the present invention independently develops and designs a relay bracket and core assembly mechanism and its assembly machine for the defects and deficiencies of the prior art, which realizes the bending and tightening of the four corners of the relay bracket by riveting, and has pre-pressing and leveling before riveting and oblique guide limit during riveting, effectively improving the riveting accuracy, and synchronously completing the oblique guide bending of the probe, improving the bending position accuracy of the probe, and effectively improving the assembly efficiency. The present invention aims to provide a relay bracket and core assembly mechanism and its assembly machine for the field of automatic assembly of relays, realizing the automatic assembly of the relay bracket and the core and the automatic bending of the relay core probe, while synchronously completing the connection assembly and the bending of the probe, effectively improving the connection assembly and the bending accuracy of the probe. Specifically, the present invention as a whole uses a bracket with a U-shaped opening structure arranged laterally as a bearing structure, the middle of which is an installation space, a driving component is provided on the top of the bracket, and the output end of the driving component extending vertically downward is connected to the riveting component and the probe bending component, and a bearing component is provided on the support of the bracket installation space, and the relay bracket, coil and core assembly to be assembled are placed on the bearing component; at the same time, oblique sliding limit components are also provided on both sides of the bearing component.
[0051] Before riveting and bending, first place the relay bracket, coil and core assembly in the bearing groove of the bearing seat of the bearing assembly. At the same time, to ensure stability, the clamping assembly arranged on the rear side of the bearing seat can output power horizontally through the clamping groove opened on the inner wall of the bearing groove to push the relay bracket forward onto the limit block on the front side of the bearing groove.
[0052] Then, a riveting cylinder driving slide arranged at the top of the bracket drives the riveting assembly and the probe bending assembly arranged at the bottom thereof to gradually approach the relay bracket downward. During the descent process, the pressure calibration block of the riveting assembly first contacts the bottom plate of the relay core, and pre-presses the bottom plate of the relay core downward from the left and right sides to achieve flatness calibration of the bottom plate and clamping and fixing before riveting, so as to ensure the surface flatness during subsequent riveting and maintain the position stability of the bottom plate, and avoid positional displacement during riveting and affect the riveting position accuracy; in addition, the pressure calibration block is slidably inserted in the first mounting groove opened on the side of the support in the vertical direction, and a buffer force is provided during pre-stressing by a pressure calibration spring. As the riveting assembly continues to descend, the pressure calibration block slides upward in the first mounting groove and compresses the pressure calibration spring; the flexible installation method of the pressure calibration block enables it to complete the pre-stressing and leveling function without generating motion interference with the descent of the pressure calibration block, and at the same time, the downward elastic pressure generated by the compression of the pressure calibration spring can continuously act downward on the pressure calibration block, so that the pressure calibration block continuously and stably presses the bottom plate of the relay chip during the riveting process.
[0053] After the pre-pressing of the bottom plate of the relay core is completed, as the slide continues to move downward, the rivet block of the rivet assembly contacts the rivet connection part of the bracket, and in the process of continuing to descend, the rivet connection part protruding vertically upward is gradually riveted to the horizontal direction and pressed against the bottom plate of the relay core from above, thereby completing the connection and fixation between the relay bracket and the relay core.

[0056] After the probe pre-pressing is completed, as the slide continues to descend, the probe bending assembly arranged on the side of the riveting assembly approaches the top of the probe, and the bending cylinder of the probe bending assembly outputs downward power to drive the lifting seat to drive the lifting block and the bending roller thereon to move downward. The bending roller gradually descends along the inclined guide arc surface arranged on the side of the above-mentioned inclined pressure guide block and adheres to the probe.
