TECHNICAL FIELD

[0001] The present application belongs to the field of automation equipment, in particular to a relay assembling and detecting integrated automatic machine. BACKGROUND

[0002] Small high-power relay is an electronic control device, mainly used in automatic control circuit, through small current and voltage to control larger current or voltage. Small high-power relay structure includes base, contact system and electromagnetic system arranged in the base and cover plate covering the base. In traditional assembly, after assembling the contact system and electromagnetic system and other components into the base, the cover plate is manually sealed to the base, and finally it is taken to another device for voltage resistance detection. The efficiency is low and does not meet the modern production demand. Therefore, the use of automatic machine is the development trend. However, some relay assembling automatic machines on the market usually have one work station with one mechanical hand to take back the material, and the transmission efficiency and stability are low. In addition, the cover pressing mechanism only uses a single pressing plate to press, which cannot ensure that the buckles on both sides of the cover plate are completely buckled to the hooks on both sides of the base.

[0029] Referring to Figures 1-11As shown, the relay assembly detection integrated automatic machine of the present application comprises a workbench 1, a workpiece conveying mechanism 2 arranged on the workbench 1, and a base carrying mechanism 3, a cover plate carrying mechanism 4, a cover plate pressing mechanism 5 and a pressure resistance detection mechanism 6 arranged in sequence beside the workpiece conveying mechanism 2. The workpiece conveying mechanism 2 comprises an upper track 7, a first clamp 8 and a lower track 9. The upper track 7 is provided with a sliding groove 10 in the middle, which is adapted to the width of the relay base 55. The first clamp 8 is arranged in the sliding groove 10 and comprises two oppositely arranged clamping rods 11 and a first clamping finger 12 for driving the clamping rods 11 to move. The middle of the clamping rod 11 is provided with a clamping finger mounting seat 13, and the two ends of the clamping rod 11 are provided with an outer baffle 14 and an inner baffle 15. The inner baffle 15 can be provided with multiple baffles according to needs. The outer clamping stations 16 are formed between adjacent outer baffles 14, and the inner clamping stations 17 are formed between adjacent inner baffles 15. The outer clamping stations 16 are provided with outer positioning grooves 18 for positioning adjacent outer baffles 14, and the inner clamping stations 17 are provided with inner positioning grooves 19 for positioning adjacent inner baffles 15, which are 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 the upper end of the lower track 9 is provided with a moving bottom plate 20 and a first telescopic cylinder 21 for driving the moving bottom plate 20 to move. The moving bottom plate 20 is provided with a lifting mechanism 22, and the first clamp 8 is installed on the lifting mechanism 22. During work, the base carrying mechanism 3 carries the relay base 55 to the outer clamping station 16 and the inner clamping station 17, and then clamps the relay base 55 through the closing of the first clamping finger 12, and finally drives the first clamp 8 to move forward through the first telescopic cylinder 21. During the conveying process, in order to prevent the relay base 55 from being scratched or stuck by the upper track 7, the lifting mechanism 22 first lifts the first clamp 8 away from the sliding groove 10.

[0030] Preferably, the lifting mechanism 22 comprises a sliding block assembly 23, a fixed seat 24 arranged on the upper end of the sliding block assembly 23, and a second telescopic cylinder 25 arranged below the fixed seat 24.

[0031] Preferably, the base carrying mechanism 3 comprises a first XY-axis sliding table 26 and a second clamping finger 27 arranged on the first XY-axis sliding table 26. The middle of the second clamping finger 27 is provided with an "L"-shaped fixed rod 28. When the relay base 55 is clamped by the second clamping finger 27, the "L"-shaped fixed rod 28 abuts against the part in the middle of the relay base 55 (mainly the electromagnetic support), so as to ensure the stability of clamping and prevent the part from loosening or falling off.

[0032] Preferably, the base conveying mechanism 3 is sequentially provided with a transfer table 29 and a dust removal mechanism 30 below, the dust removal mechanism 30 comprises a rotating support 31, a second clamp 32 provided on the rotating support 31, a rotating cylinder 33 driving the rotating support 31 to rotate, and a dust remover 34 provided on one side of the second clamp 32, the second clamp 32 comprises a worktable plate 35, two third telescopic cylinders 36 provided on the bottom of the worktable plate 35 and facing opposite directions, and a clamping plate 37 provided on the third telescopic cylinder 36, and an L-shaped stop rod 38 is provided at the front end of the clamping plate 37. The base conveying mechanism 3 first places the relay base 55 on the transfer table 29, and then conveys it to the worktable plate 35 of the second clamp 32, and then the two third telescopic cylinders 36 retract, driving the clamping plate 37 to clasp in the middle, so that the L-shaped stop rod 38 fixes the worktable plate 35, and then the rotating cylinder 33 rotates the rotating support 31, so that the relay base 55 faces downward. Finally, the dust remover 34 is used to remove dust inside the relay base 55.

[0033] Preferably, the dust remover 34 comprises a dust removal box 39, a group of air blowing pipes 40 provided on the bottom of the dust removal box 39, and a negative pressure pipe 41 provided on one side of the dust removal box 39. When the relay base 55 faces downward, align the dust removal box 39, and then the air blowing pipes 40 blow air to blow out the dust and impurities inside the relay base 55, and finally the negative pressure pipe 41 sucks away. Thus, the dust and impurities inside the relay base 55 can be more effectively removed.

[0034] Preferably, the cover plate conveying mechanism 4 comprises a second XY-axis sliding table 42 and a third clamping finger 43 provided on the second XY-axis sliding table 42, and a rubber positioning disc 44 is provided in the middle of the third clamping finger 43. When the third clamping finger 43 clamps the relay cover plate 56, the rubber positioning disc 44 abuts against the middle of the relay cover plate 56, so that the clamping is more stable. The cover plate conveying mechanism 4 is used to pre-mount the conveyed relay cover plate 56 above the relay base 55.

[0035] Preferably, the cover plate pressing mechanism 5 comprises a first sliding plate 45, a second sliding plate 46 provided on the first sliding plate 45, a pressing plate 47 mounted on the bottom of the first sliding plate 45, a pressing wheel 48 mounted on the bottom of the second sliding plate 46, a fourth telescopic cylinder 49 driving the first sliding plate 45 to slide, and a fifth telescopic cylinder 50 driving the second sliding plate 46 to slide, and at least two pressing wheels 48 are provided on both sides of the pressing plate 47. When the relay base 55 pre-mounted with the relay cover plate 56 is conveyed to below the cover plate pressing mechanism 5, the pressing plate 47 is pressed downward to press the relay cover plate 56 into the relay base 55, and at the same time, the pressing wheels 48 are also pressed downward to the two sides of the relay cover plate 56 to compact the buckles and hooks on both sides.

[0036] Preferably, the pressure resistance detection mechanism 6 comprises a sliding detection platform 51, a set of test probes 52 arranged on the sliding detection platform 51, and a sixth telescopic cylinder 53 for driving the sliding detection platform 51 to slide up and down. When the assembled relay is conveyed to below the pressure resistance detection mechanism 6, the sliding detection platform 51 slides down to contact the test probes 52 with the conductive terminals on the relay, so as to realize pressure resistance detection.

[0037] Preferably, the upper track 7 is provided with proximity sensors 54 beside the outer clamping station 16 and the inner clamping station 17, for detecting whether there is a workpiece in the outer clamping station 16 and the inner clamping station 17.
