Description

Technical Field

[0001] The invention belongs to the field of automation equipment, and in particular relates to an integrated automatic machine for relay assembly and detection. Background Art

[0002] Small, high-power relays are electronic control devices primarily used in automatic control circuits, controlling larger currents or voltages with smaller ones. A small, high-power relay consists of a base, a contact system and electromagnetic system housed within the base, and a cover covering the base. Traditionally, after the contact system and electromagnetic system are assembled into the base, the cover is manually attached to the base. Finally, the relay is taken to a separate facility for voltage resistance testing. This is inefficient and does not meet the demands of modern production. Therefore, the use of automated machines is a growing trend. However, some currently available automated relay assembly machines typically employ a single robot per workstation, returning to retrieve material, resulting in low transfer efficiency and stability. Furthermore, the cover-pressing mechanism utilizes a single pressure plate, which cannot ensure that the latches on each side of the cover fully engage with the hooks on either side of the base.

DETAILED DESCRIPTION

[0016] Reference Figures 1-11As shown, the present invention comprises an integrated relay assembly and testing machine comprising a workbench 1, a workpiece conveying mechanism 2 mounted on the workbench 1, and a base transport mechanism 3, a cover transport mechanism 4, a cover pressing mechanism 5, and a pressure resistance testing mechanism 6, which are sequentially arranged adjacent to the workpiece conveying mechanism 2. The workpiece conveying mechanism 2 comprises an upper rail 7, a first clamp 8, and a lower rail 9. A chute 10 adapted to the width of the relay base 55 is provided in the center of the upper rail 7. The first clamp 8 is disposed within the chute 10 and comprises two opposing clamping rods 11 and first clamping fingers 12 that drive the clamping rods 11. A clamping finger mounting seat 13 is provided in the center of the clamping rods 11. An outer baffle 14 and an inner baffle 15 are provided at each end of the clamping rod 11. Multiple inner baffles 15 may be provided as needed. An outer clamping station 16 is formed between adjacent outer baffles 14, and an inner clamping station 17 is formed between adjacent inner baffles 15. The outer clamping station 16 is provided with an outer positioning groove 18 for positioning the adjacent outer baffle 14, and the inner clamping station 17 is provided with an inner positioning groove 19 for positioning the adjacent inner baffle 15, which is used to limit the sliding stroke of the clamping rod 11. The power arm of the first clamping finger 12 is connected between two adjacent clamping finger mounting seats 13. The lower track 9 is arranged below the upper track 7, and its upper end is provided with a movable base plate 20 and a first telescopic cylinder 21 that drives the movable base plate 20 to move. The movable base plate 20 is provided with a lifting mechanism 22, and the first clamp 8 is mounted on the lifting mechanism 22. During operation, the base transporting mechanism 3 transports the relay base 55 to the outer clamping station 16 and the inner clamping station 17, and then clamps the relay base 55 by closing the first clamping finger 12. Finally, the first telescopic cylinder 21 drives the first clamp 8 forward. During the transport process, in order to prevent the relay base 55 from being scratched or stuck by the upper rail 7 , the lifting mechanism 22 first pushes up the first clamp 8 to move the relay base 55 away from the slide groove 10 .

[0017] Preferably, the lifting mechanism 22 includes a slider assembly 23 , a fixing seat 24 provided at the upper end of the slider assembly 23 , and a second telescopic cylinder 25 provided below the fixing seat 24 .

[0018] Preferably, the base transport mechanism 3 includes a first XY-axis slide 26 and a second gripping finger 27 mounted on the first XY-axis slide 26. An L-shaped fixing rod 28 is disposed in the middle of the second gripping finger 27. When the second gripping finger 27 grips the relay base 55, the L-shaped fixing rod 28 abuts against components in the middle of the relay base 55 (primarily the electromagnetic bracket), ensuring stable grip and preventing components from loosening or falling.

[0019] Preferably, a turntable 29 and a dust removal mechanism 30 are sequentially provided below the base transport mechanism 3. The dust removal mechanism 30 comprises a rotating bracket 31, a second clamp 32 mounted on the rotating bracket 31, a rotary cylinder 33 for rotating the rotating bracket 31, and a dust collector 34 mounted on one side of the second clamp 32. The second clamp 32 comprises a work station plate 35, two third telescopic cylinders 36 facing opposite directions and disposed at the bottom of the work station plate 35, and a clamping plate 37 mounted on the third telescopic cylinder 36. The clamping plate 37 has an L-shaped stop bar 38 at its front end. The base transport mechanism 3 first places the relay base 55 on the turntable 29 and then transports it to the work station plate 35 of the second clamp 32. The two third telescopic cylinders 36 then retract, driving the clamping plates 37 to clamp the relay base 55 toward the center, securing the L-shaped stop bar 38 to the work station plate 35. The rotating bracket 31 is then rotated by the rotary cylinder 33, so that the relay base 55 faces downward. Finally, the dust inside the relay base 55 is removed by the dust collector 34 .

[0020] Preferably, the dust collector 34 includes a dust box 39, a set of air blowing pipes 40 located at the bottom of the dust box 39, and a negative pressure pipe 41 located on one side of the dust box 39. When the relay base 55 is facing downward, the dust box 39 is aligned with the air blowing pipes 40 to blow out dust and impurities inside the relay base 55, which are then sucked away by the negative pressure pipe 41. This effectively removes dust and impurities inside the relay base 55.

[0021] Preferably, the cover plate transport mechanism 4 includes a second XY-axis slide 42 and a third gripper finger 43 mounted on the second XY-axis slide 42. A rubber positioning disc 44 is positioned in the middle of the third gripper finger 43. When the third gripper finger 43 grips the relay cover 56, the rubber positioning disc 44 abuts against the middle of the relay cover 56, ensuring a more stable grip. The cover plate transport mechanism 4 is used to pre-install the transported relay cover 56 onto the relay base 55.

[0022] Preferably, the cover plate pressing mechanism 5 includes a first sliding plate 45, a second sliding plate 46 disposed on the first sliding plate 45, a pressing plate 47 mounted on the bottom of the first sliding plate 45, a pressing roller 48 mounted on the bottom of the second sliding plate 46, a fourth telescopic cylinder 49 for driving the first sliding plate 45 to slide, and a fifth telescopic cylinder 50 for driving the second sliding plate 46 to slide. At least two pressing rollers 48 are disposed on either side of the pressing plate 47. When the relay base 55 pre-installed with the relay cover 56 is transferred to the bottom of the cover plate pressing mechanism 5, the pressing plate 47 presses down, pressing the relay cover 56 into the relay base 55. Simultaneously, the pressing rollers 48 also press down on both sides of the relay cover 56, compacting the buckles and hooks on both sides.

[0023] Preferably, the withstand voltage testing mechanism 6 includes a sliding testing platform 51, a set of test probes 52 mounted on the sliding testing platform 51, and a sixth telescopic cylinder 53 that drives the sliding testing platform 51 to slide up and down. When the assembled relay is transferred to the bottom of the withstand voltage testing mechanism 6, the sliding testing platform 51 slides down, bringing the test probes 52 into contact with the conductive terminals on the relay to perform the withstand voltage test.

[0024] Preferably, a proximity sensor 54 is provided next to the upper rail 7 corresponding to the outer clamping station 16 and the inner clamping station 17 to detect whether there is a workpiece in the outer clamping station 16 and the inner clamping station 17.

[0025] As mentioned above, the present invention is not limited in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the structure and technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
