A group of arc-shaped guide grooves are arranged on the guide blocks, and the depth of the guide grooves gradually decreases toward the end away from the right-angle terminal straight vibrator. The guide pins at the two ends of the material distribution plate are abutted and limited in the guide grooves. As the material distribution plate one flips toward the end away from the right-angle terminal straight vibrator, the material distribution plate two compresses the spring under the push of the guide pin and the guide groove, driving the right-angle terminal to move toward the docking plate in front, and abuts against the docking plate.

At this time, the product clamp 2 rotates to the top of the right-angle terminal rubbing device to clamp the top of the right-angle terminal. Then, the driving end of the rubbing linear module drives the guide block to retreat, and the dividing plate 2 also retreats relative to the dividing plate 1 under the push of the spring, so that the right-angle terminal is separated from the receiving groove for the product clamp 2 to grab the right-angle terminal for transfer. At this point, the rubbing transition of the right-angle terminal can be completed, the degree of automation is higher, and the work is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Example 2

[0045] A production line for assembling and inspecting T-type plungers and right-angle terminals of a high-voltage contact relay is disclosed. In the present embodiment, it is a further limitation based on Embodiment 1, wherein a bottom shell feeding portion 2 comprises a bottom shell vibrator 21 for driving the bottom shell feeding and a rotating gripper 22 for grabbing the bottom shell at the discharge end of the bottom shell vibrator 21 to a carrier 6 rotated into place.

The bottom shell clamp 221, the bottom shell lifting cylinder 222 and the bottom shell rotating cylinder 223 are all prior art and will not be described in detail here.

[0046] A plasma cleaner 7 is arranged on the fixed plate 5 on one side of the bottom shell loading part 2, and a plasma cleaning protective cover 8 aligned with the nozzle of the plasma cleaner 7 is also arranged on the mounting support for mounting the bottom shell rotating cylinder 223. At this point, this arrangement can also perform plasma cleaning on the bottom shell after the bottom shell is loaded and before assembly to improve the neatness of the assembly.

[0047] The rotating cam 32 includes a cam plate 321 driven to rotate by a cam motor 322, and a plurality of groups of plunger holes 323 for accommodating T-type plungers are provided around the periphery of the cam plate 321. When a group of plunger holes 323 rotate to a horizontal position and dock with the discharge end of the T-type plunger vibration plate 31, the T-type plunger is driven by the T-type plunger vibration plate 31 to be inserted into the plunger hole 323. When the plunger hole 323 rotates to a vertical top end, the T-type plunger transport module 33 adsorbs the T-type plunger on the rotating cam 32 and transports it to the top of the carrier 6 for assembly into the bottom shell.

[0048] The T-type plunger transport module 33 includes a T-type plunger horizontal transport cylinder 331, a T-type plunger lifting cylinder 332, an adsorption head 333, and a T-type plunger slide 334. The adsorption head 333 is installed on the driving end of the T-type plunger lifting cylinder 332, and the T-type plunger lifting cylinder 332 is installed on the T-type plunger slide rail 335 through the T-type plunger slide 334, and is driven by the T-type plunger horizontal transport cylinder 331 to move back and forth between the cam disk 321 and the carrier 6.

The clamping mechanism 9 includes a clamping block 91 and a clamping cylinder 92 for driving the clamping block 91 to rise and fall. The clamping block 91 is used to press against the bottom shell, and a group of through holes 93 for the T-type plunger to pass through are also arranged in the center. Therefore, when assembling the T-type plunger, the clamping block 91 can be pressed against the bottom shell to ensure the stability of the bottom shell when the T-type plunger is placed.

Two sets of product clamps 424 are symmetrically arranged on both sides of the right-angle terminal mounting frame 423. The product clamps 424 are used to hold the bottom shell and move back and forth between the carrier 6 and the product fixture 411;

[0051] The right-angle terminal handling module 2 43 includes a right-angle terminal handling cylinder 2 431, a right-angle terminal mounting frame 2 432 driven by the right-angle terminal handling cylinder 2 431 to rotate horizontally, and two groups of right-angle terminal lifting cylinders 2 433 are symmetrically arranged on both sides of the right-angle terminal mounting frame 2 432. The driving end of the right-angle terminal lifting cylinder 2 433 is installed with a product clamp 2 434, which is used to clamp the right-angle terminal loading assembly to the bottom shell in the product fixture 411;

[0052] At this point, a rotating mechanism 41 is set up for the transition of the intermediate assembly, so as to ensure that the product clamp 2 434 can be rotated to the top of the bottom shell at different positions during assembly, so as to cooperate with the assembly of the right-angle terminals in the mounting grooves at different positions on the bottom shell, and the flexibility and stability adaptability are better.

[0053] The right-angle terminal assembly part 4 also includes a right-angle terminal vibrator 44, and the tail end of the right-angle terminal vibrator 44 is connected to a right-angle terminal rubbing device 45, which is used to vibrate and convey the right-angle terminal. This device is in the prior art and will not be described in detail here. The right-angle terminal rubbing device 45 includes a rubbing rotating cylinder 451 installed on the rubbing frame, a distribution plate 452 installed on the driving end of the rubbing rotating cylinder 451, and a distribution plate 453 is slidably installed on one side of the distribution plate 452. A group of fixed blocks 454 are arranged on the distribution plate 452 and the distribution plate 453, and the two groups of fixed blocks 454 are abutted by springs. A group of magnetic blocks 455 are provided at the end of the material distribution plate 52, and a receiving groove 456 is provided at the end of the material distribution plate 453. The receiving groove 456 is used to receive the feeding of a group of right-angle terminals when the material distribution plate 1 452 is rotated to dock with the discharge end of the right-angle terminal straight vibrator 44, and one end of the right-angle terminal of the feeding is fixed against the magnetic block 455. At this point, when the material distribution plate 1 452 is rotated to dock with the discharge end of the right-angle terminal straight vibrator 44, a group of right-angle terminals can be loaded into the receiving groove 456, and the magnetic block 455 can magnetically fix the right-angle terminals entering the receiving groove 456. The rubbing rotating cylinder 451 is used to drive the material distribution plate 1 452 to feed. 2 is flipped 180°, and a group of guide blocks 457 are installed on the rubbing frame through the rubbing linear module 458, and a group of arc-shaped guide grooves 459 are arranged on the guide blocks 457, and the depth of the guide grooves 459 is gradually reduced toward the end away from the right-angle terminal straight vibrator 44, and a group of guide pins abutting and limiting in the guide grooves 459 are provided at the end of the distribution plate 453, and as the distribution plate 1 452 is flipped toward the end away from the right-angle terminal straight vibrator 44, the distribution plate 2 453 compresses the spring under the push of the guide pins and the guide grooves 459, drives the right-angle terminal to move toward the docking plate 4510 in front, and abuts against the docking plate 4510. When plate 4510 is moved, the guide pin rotates to the end of the guide groove 459, so that the top of the right-angle terminal can be ensured to be away from the magnetic attraction of the magnetic block 455. At this time, the product clamp 2 434 rotates to the top of the right-angle terminal rubbing device 45 to clamp the top of the right-angle terminal. Then, the driving end of the rubbing linear module 458 drives the guide block 457 to retreat, and the dividing plate 2 453 also retreats relative to the dividing plate under the push of the spring, so that the right-angle terminal is separated from the receiving groove 456 for the product clamp 2 434 to grab the right-angle terminal for transfer. At this point, the rubbing transition of the right-angle terminal can be completed, the degree of automation is higher, and the work is more stable.

[0054] The working principle of the present invention is as follows: the assembly and testing production line of the T-shaped plunger and the right-angle terminal of the high-voltage contact relay provided by the present invention can realize the automatic and continuous rapid assembly of the T-shaped plunger and the right-angle terminal to the bottom shell, with higher processing efficiency and better processing stability;

[0055] During the loading and assembly of the T-type plunger, a rotating cam plate 321 is provided to sequentially receive the transition of the T-type plunger. When the plunger hole 323 of the cam plate 321 rotates to a horizontal position, it is used to receive the material, and when it rotates to a vertical top end, it is provided for the suction head 333 above to absorb the material. Then, during the assembly of the T-type plunger, the pressing block 91 is pressed against the bottom shell to ensure the stability of the bottom shell when the T-type plunger is placed. During the overall process, each component can act synchronously, thereby greatly improving the processing efficiency.

[0056] When loading and assembling the right-angle terminals, a right-angle terminal rubbing device 45 is set, and one side of the dividing disc 1 452 is slidably installed with the dividing disc 2 453, and the dividing disc 1 452 and the dividing disc 2 453 are installed by spring abutment. A group of magnetic blocks 455 are provided at the end of the dividing disc 1 452, and a receiving groove 456 is provided at the end of the dividing disc 2 453. The receiving groove 456 is used to receive the feeding of a group of right-angle terminals when the dividing disc 1 452 is rotated to dock with the discharge end of the right-angle terminal straight vibrator 44, and one end of the fed right-angle terminal is fixed on the magnetic block 455. At this point, when the dividing disc 1 452 is rotated to dock with the discharge end of the right-angle terminal straight vibrator 44, a group of right-angle terminals can be loaded into the receiving groove 456, and the magnetic block 455 can magnetically fix the right-angle terminals entering the receiving groove 456.

[0057] Then the material rubbing rotary cylinder 451 drives the feeding material distribution plate 1 452 to flip 180 degrees, and a group of guide blocks 457 are installed on the material rubbing frame through the material rubbing linear module 458. A group of arc-shaped guide grooves 459 are arranged on the guide block 457, and the depth of the guide groove 459 gradually decreases toward the end away from the right-angle terminal straight vibrator 44, and the guide pin at the end of the material distribution plate 2 453 is abutted and limited in the guide groove 459. As the material distribution plate 1 452 flips toward the end away from the right-angle terminal straight vibrator 44, the material distribution plate 2 453 compresses the spring under the push of the guide pin and the guide groove 459, driving the right-angle terminal to move toward the docking plate 4510 in the front, and When abutting against the docking plate 4510, the guide pin rotates to the end of the guide groove 459, thereby ensuring that the top of the right-angle terminal is away from the magnetic attraction of the magnetic block 455. At this time, the product clamp 2 434 rotates to the top of the right-angle terminal rubbing device 45 to clamp the top of the right-angle terminal. Then, the driving end of the rubbing linear module 458 drives the guide block 457 to retreat, and the dividing plate 2 453 also retreats relative to the dividing plate 1 under the push of the spring, so that the right-angle terminal is disengaged from the receiving groove 456 for the product clamp 2 434 to grab the right-angle terminal for transfer. At this point, the rubbing transition of the right-angle terminal can be completed, with a higher degree of automation and more stable operation.
