Description

Technical Field

[0001] This application relates to the field of terminal manufacturing equipment, and more particularly to a riveting device for terminals. Background Technology

[0002] A micro switch is a contact mechanism with tiny contact intervals and a quick-acting mechanism that performs switching actions with a specified stroke and a specified force. The terminal is an important component of a micro switch, responsible for connecting the switch to the external circuit.

[0003] Reference Figure 1 The high-current micro switch terminal involved in this application includes a terminal body 1 and a silver dot 2. A silver dot mounting hole 11 is provided on the end of the terminal body 1, and the silver dot 2 is riveted into the silver dot mounting hole 11 of the terminal body 1. The terminal body 1 is a relatively thin flat plate structure, and two opposing grooves 12 are respectively provided on the two opposite sidewalls of the terminal body 1. For terminals with the above structure, existing terminal riveting equipment has a low degree of automation in terminal processing. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application provides a riveting device for terminals.

[0005] This application provides a terminal riveting device, which adopts the following technical solution:

[0006] A terminal riveting device includes a transmission mechanism for transmitting terminal bodies; a terminal feeding mechanism for transmitting terminal bodies to the transmission mechanism; a silver dot feeding mechanism for transmitting silver dots to the terminal bodies on the transmission mechanism; and a riveting mechanism for riveting the terminal bodies and silver dots on the transmission mechanism. The transmission mechanism is capable of transmitting terminal bodies to the silver dot feeding mechanism and the riveting mechanism.

[0007] By adopting the above technical solution, during terminal riveting, the terminal body is transferred to the transmission mechanism via the terminal feeding mechanism, then to the silver dot feeding mechanism, and finally the silver dots are transferred to the terminal body on the transmission mechanism. The riveting mechanism then rivets the silver dots. This fully automates the feeding, transmission, and riveting processes in terminal production, greatly improving the automation level of the equipment and increasing production efficiency.

[0008] Optionally, the terminal feeding mechanism includes a feeding component and a terminal misalignment component. The terminal misalignment component includes a terminal misalignment seat and a terminal misalignment driving source. The feeding component is used to transfer the terminal body to the terminal misalignment seat. The terminal misalignment driving source is used to drive the terminal misalignment seat to move to align with the feeding component. The terminal misalignment driving source is also used to drive the terminal misalignment seat to move to align with the transmission mechanism. The feeding component and the transmission mechanism are misaligned in a direction perpendicular to the transmission direction of the feeding component.

[0009] By adopting the above technical solution, the terminal body is conveyed to the terminal misalignment seat by the material conveying component, and then the terminal misalignment drive source drives the terminal misalignment seat to form a misalignment with the material conveying component and align with the transmission mechanism, so that the terminal body behind will not be sent to the terminal misalignment seat by the material conveying component and cause interference.

[0010] Optionally, the terminal misalignment assembly further includes a fixing seat, the terminal misalignment seat being slidably disposed on the fixing seat, the fixing seat having a stop block penetrating the terminal misalignment seat, and the stop block being located on the transmission path of the terminal body; when the terminal misalignment seat moves to align with the transmission mechanism, the stop block moves out of the transmission path of the terminal body.

[0011] By adopting the above technical solution, the stop block blocks the terminal body, preventing it from moving excessively due to inertia. When the terminal misalignment seat is aligned with the transmission mechanism, the terminal misalignment seat is moved by the terminal misalignment drive source, and the stop block moves relative to the terminal misalignment seat so that the stop block no longer blocks the terminal body, allowing the terminal body to be transmitted onto the transmission mechanism.

[0012] Optionally, the terminal feeding mechanism further includes a pushing component. The feeding component and the pushing component are arranged sequentially along the transmission direction of the terminal body. The pushing component is used to transfer the terminal body on the terminal misalignment seat to the transmission mechanism.

[0013] By adopting the above technical solution, the terminal body is transported over long distances via a feeding assembly. When the terminal body is transported from the feeding assembly to the terminal misalignment seat, the pushing assembly transfers the terminal body from the misalignment seat to the transmission mechanism. Through a two-stage feeding setup, the feeding assembly enables rapid transmission, while the pushing assembly ensures precise feeding, guaranteeing both transmission speed and feeding accuracy.

[0014] Optionally, the pushing assembly includes a pushing claw and a pushing drive source. The pushing drive source is used to drive the pushing claw to move in a direction close to the transmission mechanism. The pushing drive source is also used to drive the pushing claw to move in a direction away from the transmission mechanism. The pushing claw is used to push the terminal body on the terminal misalignment seat onto the transmission mechanism. The pushing claw is provided with a limiting block, which is used to insert into the slot of the terminal body.

[0015] By adopting the above technical solution, the terminal body is driven to move relative to the pusher claw by the terminal misalignment component. This causes the limiting block of the pusher claw to insert into the slot of the terminal body, thereby causing the limiting block to abut against the slot wall of the terminal body and pushing the terminal body to move. The limiting block plays a role in pushing and guiding the terminal body, improving the stability of the terminal body's push. The pusher claw structure occupies little space, making it easy to install in confined spaces.

[0016] Optionally, the pusher assembly further includes a pusher seat, the pusher claw is rotatably mounted on the pusher seat, the rotation axis of the pusher claw is perpendicular to the moving direction of the terminal misalignment seat and the transmission direction of the terminal body on the terminal misalignment seat, the pusher drive source is used to drive the pusher seat to move, and a reset elastic element for resetting the pusher claw is connected between the pusher claw and the pusher seat.

[0017] By adopting the above technical solution and incorporating a reset elastic element, after the terminal body is conveyed to the transmission mechanism, the pusher drive source drives the pusher seat to retract. The groove wall of the terminal body's slot abuts against the limiting block, causing the pusher claw to rotate against the elastic force of the reset elastic element. This causes the limiting block to disengage from the terminal body's slot. Once the terminal pusher has completely disengaged from the terminal body, the reset elastic element drives the pusher claw to reset. This structure is simple, easy to reset, and saves energy. Compared to using multiple drive sources with different driving directions, this pusher assembly only requires a single-direction drive source, making the drive source setup simpler and improving mechanical reliability.

[0018] Optionally, the pusher seat is provided with a limiting rod, and the pusher claw is provided with a limiting groove. The limiting rod is used to abut against the groove wall of the limiting groove, and the reset elastic element is used to drive the pusher claw to rotate until the groove wall of the limiting groove abuts against the limiting rod.

[0019] By adopting the above technical solution, the excessive rotation of the pusher claw can be prevented by the limit rod abutting against the wall of the limit groove. The reset elastic element cooperates with the limit rod to ensure that the pusher claw can rotate away from the terminal body, but prevents the pusher claw from rotating indefinitely during the pushing process of the terminal body, thereby improving the stability of the pusher claw's movement and the reliability of automation.

[0020] Optionally, the transmission mechanism includes a clamp, which includes a base and a clamping piece. The clamping piece is rotatably mounted on the base and includes a pressing part. A pressing elastic member for pressing the pressing part against the terminal body is connected between the base and the clamping piece.

[0021] By adopting the above technical solution, during the transfer of the terminal body, the pusher assembly transfers the terminal body between the clamping part and the base, where the clamping part and the base clamp the terminal body. The clamping elastic element keeps the clamp in a clamped state, eliminating the need for a drive source to drive the clamp to clamp the terminal body, thus saving energy.

[0022] Optionally, the base has a clamping groove for placing the terminal body, the clamping piece has an abutment block, and the clamping elastic member is used to drive the abutment block to abut the bottom wall of the clamping groove. When the abutment block abuts the bottom wall of the clamping groove, the side wall of the clamping piece, the abutment block and the clamping groove form a clamping cavity for inserting the terminal body. A guide slope is formed on the end of the clamping part near the terminal feeding mechanism. The distance between the guide slope and the bottom wall of the clamping groove decreases along the transmission direction of the terminal feeding mechanism.

[0023] By adopting the above technical solution, and by setting the abutment block and the guide slope, the terminal body can slide along the guide slope and overcome the elastic force of the abutment elastic element to lift the abutment part and insert it into the clamping cavity. This makes it convenient for the terminal feeding mechanism to directly transfer the terminal body into the clamping cavity. There is no need for the drive source to drive the clamping plate away from the base to make room for the terminal body, which saves energy and improves production efficiency.

[0024] Optionally, it also includes a discharge mechanism, which includes a discharge drive source and a discharge claw. The discharge drive source is used to drive the discharge claw to move. The discharge claw is provided with a push block, which is used to insert into the slot of the terminal body.

[0025] By adopting the above technical solution, the push block of the discharge claw is inserted into the slot of the terminal body, so that the push block abuts against the side wall of the slot of the terminal body to push the terminal body to move and discharge. The push block plays a role in pushing and limiting the terminal body, which improves the stability of the terminal body discharge. The structure of the discharge claw occupies less space and is easy to install in a narrow space.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. It improved the automation level of the equipment and increased production efficiency;

[0028] 2. The limiting block plays a role in pushing and limiting the terminal body, which improves the stability of pushing the terminal body. The pusher claw structure occupies less space and is easy to install in a narrow space.

[0029] 3. The reset elastic element drives the pusher claw to reset, which is simple in structure, easy to reset, saves energy, and the pusher drive source is easy to set. Attached Figure Description

The first transmission block 442 is fixedly connected to the drive rod of the feeding drive source 441. The second transmission block 443 is L-shaped and rotatably mounted on the movable seat 419. The two ends of the second transmission block 443 are hinged to the first transmission block 442 and the third transmission block 444, respectively. The feeding drive source 441 drives the first transmission block 442 to move, the first transmission block 442 drives the second transmission block 443 to rotate, and the second transmission block 443 drives the third transmission block 444 to rotate. The third transmission block 444 is hinged to a sliding block 4191, which moves along a direction perpendicular to the transmission direction of the terminal feeding track 414 and the movement direction of the rack 416. The feeding drive source 441 is used to drive the sliding block 4191 to move and align with the terminal vibratory feeder 411. The feeding drive source 441 is also used to drive the sliding block 4191 to move and align with the terminal conveying track 414. The terminal vibratory feeder 411 and the terminal conveying track 414 are offset along the conveying direction of the terminal conveying track 414. When the sliding block 4191 is aligned with the terminal vibratory feeder 411, the flipping assembly 412 completes the flipping of the terminal body.

[0050] Reference Figure 5 The terminal feeding mechanism 4 also includes a terminal misalignment assembly 42, which includes a terminal misalignment seat 421, a terminal misalignment drive source 422, and a fixed base 423. A terminal feeding track 414 is used to transport the terminal body to the terminal misalignment seat 421. The terminal misalignment seat 421 is slidably mounted on the fixed base 423 in a vertical direction, and the terminal misalignment drive source 422 is fixedly mounted on the fixed base 423. The terminal misalignment drive source 422 is used to drive the terminal misalignment seat 421 to move and align with the terminal feeding track 414. The terminal misalignment drive source 422 is also used to drive the terminal misalignment seat 421 to move and align with the transmission mechanism 3. The terminal feeding track 414 and the transmission mechanism 3 are misaligned in a direction perpendicular to the transmission direction of the terminal feeding track 414.

[0051] Reference Figure 5 and Figure 6 The riveting equipment also includes a terminal detection mechanism 8, which includes a first detection component 81. The first detection component 81 is used to detect whether the terminal body on the terminal misalignment seat 421 has been transferred into place. A stop 424 that penetrates the terminal misalignment seat 421 is fixedly installed on the fixed base 423. When the terminal misalignment seat 421 is aligned with the terminal feeding track 414, the stop 424 is located on the transmission path of the terminal body, and the stop 424 abuts and blocks the terminal body. At this time, the first detection component 81 detects whether there is a terminal body on the terminal misalignment seat 421 by infrared detection. If there is, the terminal misalignment drive source 422 drives the terminal misalignment seat 421 to move to align with the transmission mechanism 3. When the terminal misalignment seat 421 is aligned with the transmission mechanism 3, the stop 424 moves out of the transmission path of the terminal body, and the stop 424 releases its obstruction of the terminal body.

The pushing drive source 432 is used to drive the pushing claw 431 to move in a direction close to or away from the transmission mechanism 3. The pushing claw 431 is used to transfer the terminal body on the terminal misalignment seat 421 to the transmission mechanism 3. Multiple limiting blocks 433 are integrally formed on the end of the pushing claw 431 near the terminal misalignment seat 421 corresponding to the slot. When the terminal misalignment seat 421 moves to align with the transmission mechanism 3, the limiting blocks 433 are inserted into the slot of the terminal body.

The first detection assembly 81 is fixedly installed on the feeding base 434, and the feeding claw 431 is rotatably installed on the feeding base 434. The rotation axis of the feeding claw 431 is perpendicular to the moving direction of the terminal misalignment seat 421 and the transmission direction of the terminal feeding track 414. When the terminal body is transmitted to the transmission mechanism 3, the feeding claw 431 rotates to disengage the limiting block 433 from the slot. The drive rod of the feeding drive source 432 is fixedly connected to the feeding base 434, and the feeding drive source 432 is used to drive the feeding base 434 to move.

[0054] Reference Figure 5 and Figure 6 and Figure 7 A reset elastic element 435, which is a tension spring, connects the pusher claw 431 and the pusher seat 434. The reset elastic element 435 drives the pusher claw 431 to rotate and reset, so that the pusher claw 431 rotates to the state where the limiting block 433 is inserted into the slot. A limiting rod 436 is fixedly installed on the pusher seat 434. The limiting rod 436 is parallel to the rotation axis of the pusher claw 431, and the limiting rod 436 and the rotation axis of the pusher claw 431 are arranged sequentially along the transmission direction of the terminal feeding track 414. A limiting groove 437 is formed on the pusher claw 431. When the pusher claw 431 is in the state where the limiting block 433 is inserted into the slot under the elastic force of the reset elastic element 435, the limiting rod 436 abuts against the groove wall of the limiting groove 437.

[0055] Reference Figure 2 and Figure 8 The transmission mechanism 3 includes a rotating seat 32 and multiple clamps 31 fixedly mounted on the rotating seat 32. The rotating seat 32 is driven by a motor to rotate. The rotating seat 32 is used to rotate so that the clamps 31 correspond to different work positions. The multiple clamps 31 are evenly distributed around the rotation axis of the rotating seat 32.

[0056] Reference Figure 7 and Figure 8 The clamp 31 includes a base 311 and a clamping piece 312.

The clamping piece 312 includes a pressing part 313 and a connecting part 319, which are located on opposite sides of the rotation axis of the clamping piece 312. A pressing elastic member 314, which is a compression spring, is press-fitted between the connecting part 319 and the base 311. The pressing elastic member 314 drives the clamping piece 312 to rotate, so that the pressing part 313 presses the terminal body against the base 311. The elastic force of the pressing elastic member 314 is greater than the elastic force of the reset elastic member 435.

[0057] Reference Figure 5 and Figure 8 The base 311 has a clamping groove 315 for accommodating the terminal body. An abutment block 316 is integrally formed on the clamping piece 312, located between the connecting part 319 and the clamping part 313. A clamping elastic member 314 drives the abutment block 316 to abut the bottom wall of the clamping groove 315. At this time, the side wall of the clamping part 313 near the base 311, the side wall of the abutment block 316, and the bottom wall of the clamping groove 315 enclose a clamping cavity 317 for inserting the terminal body. A guide slope 318 is formed on the side wall of the clamping part 313 near the base 311. The distance between the guide slope 318 and the bottom wall of the clamping groove 315 gradually decreases along the transmission direction of the terminal feeding track 414. The guide slope 318 guides the terminal body to lift the clamping part 313 and insert it into the clamping cavity 317.

The clamp 31 and the silver dot conveying track 512 are misaligned along the conveying direction of the silver dot conveying track 512. The silver dot misalignment drive source 521 drives the silver dot misalignment seat 522 to move until it aligns with the silver dot conveying track 512. The silver dot misalignment drive source 521 also drives the silver dot misalignment seat 522 to move until it aligns with the clamp 31. The silver dot misalignment drive source 521 misaligns the silver dots on the silver dot misalignment seat 522 with the silver dots on the silver dot conveying track 512, facilitating the suction cup assembly 53 to pick up the silver dots.

[0061] Reference Figure 10 The suction cup assembly 53 includes a motion drive source 531, a suction cup drive source 532, and a suction cup 533. The suction cup is used to pick up the silver dots. The suction cup drive source 532 is used to drive the suction cup 533 to move vertically, so that the suction cup 533 moves closer to or away from the silver dots. The motion drive source 531 is used to drive the suction cup 533 to move along the transmission direction of the silver dot conveying track 512, so as to move the suction cup 533 from the silver dot misalignment seat 522 to the clamp 31. The suction cup assembly 53 is used to transport the silver dots on the silver dot misalignment seat 522 to the clamp 31.

The discharge drive source 71 drives the discharge jaw 72 to move horizontally towards or away from the clamp 31. A push block 721 is integrally formed on the discharge jaw 72. The translation drive source 73 drives the discharge jaw 72 to move vertically towards the clamp 31, so that the push block 721 is inserted into the slot of the terminal body.
