Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a multi-station automated assembly equipment. Background Technology

[0002] In the field of electrical fittings, clamp assemblies used to mate with electrical junction boxes typically consist of a base plate, clamps, a connecting plate, and a screw. The connecting plate has a first connecting portion and a second connecting portion spaced apart. The base plate and clamps are stacked between the first and second connecting portions. The base plate has a slot for the screw to pass through, and the clamps have threaded holes for the screw to mate with it. During assembly, the first end of the screw is first threadedly connected to the first connecting portion of the connecting plate. Then, the screw shaft slides through the slot in the base plate, threaded through the threaded hole in the clamp, and finally, the second end of the screw is threadedly connected to the second connecting portion of the connecting plate, thus initially positioning the base plate and clamps on the connecting plate. After assembly, to prevent the screw from loosening and failing during use, the ends of the screw need to be riveted.

[0003] Currently, the production and assembly process of the aforementioned clamping components still relies primarily on manual labor. During operation, workers must first manually place and position the base plate, clamping plates, and connecting plates according to their assembly relationship. Then, they manually screw in and tighten the screws one by one, initially securing the parts together. After tightening, the assembled components are manually transferred to an independent riveting device for riveting the screw ends. This manual operation method has significant drawbacks: First, the entire assembly process involves multiple steps, requiring substantial manpower and resulting in high labor intensity for workers. Furthermore, frequent material handling and transfer between steps leads to low assembly efficiency, making it difficult to meet the pace requirements of large-scale, mass production. Second, when manually screwing in the screws, the tightening force and insertion distance depend entirely on the operator's experience and feel, making it difficult to maintain consistency and easily causing uneven component tightness, affecting product reliability. Summary of the Invention

[0006] Furthermore, the turntable assembly includes a rotating plate, on which four sets of clamping assemblies are evenly arranged around the circumference of rotation, and a cam divider for driving the rotating plate to rotate is provided on the base.

[0007] Furthermore, the mold is fixed on the rotating plate, and the mold is provided with a first cylinder for driving the clamping block to slide; the second positioning cavity is recessed below the first positioning cavity, and the mold is provided with a first abutting block for positioning the base plate and the clamping piece, the first abutting block being connected to the second cylinder; the mold is provided with a second abutting block for positioning the connecting plate, one side of the connecting plate abutting against the clamping block, and the other side being abutted by the second abutting block, the second abutting block being connected to a third cylinder.

[0009] Furthermore, the twisting station includes a main frame, a drive motor, a twisting head, a feeding clamp, and an auxiliary push rod that works with the drive motor to lift and lower. The main frame is equipped with a main push rod, which is connected to a lifting slider. The auxiliary push rod is located on the lifting slider, and the lower end of the lifting slider is connected to the feeding clamp. One end of the twisting head is connected to the drive motor shaft, and the other end is placed inside the feeding clamp.

[0010] Furthermore, the feeding clamp includes symmetrically arranged clamp bodies. The upper end of the clamp body is rotatably connected to the lower end of the lifting slider via a rotating shaft. The lower end is provided with a hole for the threaded end of the screw to pass through. A return torsion spring is provided between the clamp body and the rotating shaft. A feeding pipe for feeding the screw is provided on either side of the clamp body.

[0011] Furthermore, the riveting station includes a riveting machine that is lifted and mounted on a base. The riveting machine includes symmetrically arranged pressure blocks, and each pressure block is connected to a drive push rod. The base is provided with a lifting push rod, and the lifting push rod is provided with a riveting seat. The pressure blocks are symmetrically slidably mounted on the riveting seat.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-8 .

[0025] A multi-station automated assembly equipment includes a base 1, a turntable assembly 2 mounted on the base 1, and a plurality of clamping assemblies 3 mounted on the turntable assembly 2. The base 1 is provided with an assembly station 4, a screwing station 5, a riveting station 6, and a material picking station 7 that cooperate with the clamping assemblies 3.

[0026] The clamping assembly 3 includes a mold 301 for positioning the base plate 11 and the clamping piece 12. The mold 301 is provided with a first positioning cavity 13 that matches the shape of the base plate 11 and a second positioning cavity 14 that matches the shape of the clamping piece 12. Clamping blocks 302 for clamping the connecting plate 15 are symmetrically slidably provided on both sides of the mold 301.

[0027] Assembly station 4 is used to place base plate 11, clamping plate 12 and connecting plate 15. Tightening station 5 is used to automatically assemble screw 16 from top to bottom through the pre-assembled parts on clamping assembly 3. Riveting station 6 is used to rivet the lower end of screw 16. Material removal station 7 is used to remove and transfer the assembled clamping plate assembly on clamping assembly 3.

[0028] The rotation of the turntable assembly 2 causes the clamping assembly 3 to pass through the assembly station 4, the screwing station 5, the riveting station 6, and the material picking station 7 in sequence, thereby realizing the combination assembly and conveying of the clamping plate assembly.

[0029] The turntable assembly 2 includes a rotating plate 201, on which four sets of clamping components 3 are evenly arranged around the circumference of rotation. The base 1 is provided with a cam divider 202 for driving the rotating plate 201 to rotate. The cam divider 202 drives the rotating plate 201 to rotate intermittently, rotating 90 degrees each time, so that each set of clamping components 3 switches between each workstation in sequence.

[0030] The mold 301 is fixed on the rotating plate 201, and the mold 301 is provided with a first cylinder 303 for driving the clamping block 302 to slide. The second positioning cavity 14 is recessed below the first positioning cavity 13. The mold 301 is provided with a first abutting block 304 for positioning the base plate 11 and the clamping piece 12 on the side away from the center of the rotating plate 201. The first abutting block 304 is connected to the second cylinder 305. In use, the first abutting block 304 is moved closer to the center of the rotating plate 201, so that the first abutting block 304 abuts against the outer wall of the base plate 11 and the clamping piece 12 to form a positioning. The wall on the other side of the base plate 11 and the clamping piece 12 abuts against the inner wall of the first positioning cavity 13 and the second positioning cavity 14. The mold 301 is provided with a second abutment block 306 for positioning the connecting plate 15. One side wall of the connecting plate 15 abuts against the clamping block 302, and the other side is abutted by the second abutment block 306. The second abutment block 306 is connected to a third cylinder 307, thereby clamping the connecting plate 15 between the second abutment block 306 and the clamping block 302. Figure 4 As shown.

[0031] The clamping block 302 is provided with a positioning groove 308 that matches the shape of the connecting plate 15 and a guide hole 309 for the screw 16 to pass through. The positioning groove 308 can precisely limit the two side walls of the connecting plate 15, and the guide hole 309 plays a guiding role when the screw 16 is inserted, ensuring that the screw 16 accurately enters the corresponding connecting hole of the connecting plate 15.

[0032] The mold 301 is also provided with a feeding groove 31 for pre-placing the clamping piece 12. The assembly station 4 includes a feeding cylinder 32 corresponding to the feeding groove 31. After the feeding cylinder 32 is lifted, it can lift the bottom surface of the clamping piece 12 to the same level as the bottom of the second positioning cavity 14. Then, the clamping piece 12 is pushed into the second positioning cavity 14 through the first abutting block 304 to ensure that the threaded hole of the clamping piece 12 is aligned with the guide hole 309 on the clamping block 302.

[0033] The twisting station 5 includes a main frame 41, a drive motor 401, a twisting head 402, a feeding clamp 403, and an auxiliary push rod 404 that works with the drive motor 401 to lift and lower it. The main frame 41 is equipped with a main push rod 42, which is connected to a lifting slider 43. The auxiliary push rod 404 is located on the lifting slider 43, and the lower end of the lifting slider 43 is connected to the feeding clamp 403. One end of the twisting head 402 is connected to the shaft of the drive motor 401, and the other end is placed inside the feeding clamp 403.

[0034] The feeding clamp 403 includes symmetrically arranged clamping bodies 405. The upper end of the clamping body 405 is rotatably connected to the lower end of the lifting slider 43 via a rotating shaft. The lower end is provided with a hole for the threaded end of the screw 16 to pass through. A return torsion spring is provided between the clamping body 405 and the rotating shaft. A feeding pipe 406 for feeding the screw 16 is provided on either side of the clamping body 405. The screw 16 enters the feeding clamp 403 through the feeding pipe 406. The main push rod 42 drives the lifting slider 43 and the feeding clamp 403 to move downward as a whole, so that the lower end of the feeding clamp 403 abuts and aligns with the clamping block 302. The auxiliary push rod 404 drives the drive motor 401 and the screwing head 402 to move downward. The screwing head 402 drives the screw 16 to rotate and pass downward through the guide hole 309 on the clamping block 302 and the pre-installed base plate 11 and clamping piece 12. Finally, the lower end of the screw 16 is threadedly connected to the second connecting part on the lower side of the connecting plate 15, completing the screwing assembly and forming a screw clamp. Figure 8 The clip assembly shown.

[0035] The riveting station 6 includes a riveting machine 61 that is raised and lowered on the base 1. The riveting machine 61 includes symmetrically arranged pressure blocks 62, and each pressure block 62 is connected to a drive push rod 63. A lifting push rod is provided on the base 1, and a riveting seat 64 is provided on the lifting push rod. The pressure blocks 62 are symmetrically slidably arranged on the riveting seat 64. When the clamping assembly 3 carrying the assembled assembly arrives at the riveting station 6, the lifting push rod drives the riveting seat 64 upward. Subsequently, the pressure blocks 62 move towards each other to clamp and rivet the lower end of the screw 16, deforming its end to form... Figure 8 The flat-headed screw section shown prevents screw 16 from loosening.

[0036] The material handling station 7 includes a linear module 71, on which a material handling cylinder 72 is mounted. The material handling cylinder 72 is connected to a material handling positioning component 73, which has a suction cup 74 that mates with the clamping assembly. The material handling positioning component 73 is a frame-shaped component and is equipped with a proximity switch 75 to detect whether it has approached the product to the corresponding suction height. The suction cup 74 is connected to the material handling positioning component 73 via a connecting rod 76. The material handling positioning component 73 has several adjustment holes 77 that mate with the connecting rod 76. One end of the connecting rod 76 is fixedly connected to the adjustment holes 77 by bolts. By selecting different adjustment holes 77, the position of the suction cup 74 can be adjusted to accommodate clamping assemblies of different sizes and specifications.

[0037] The working principle of this invention is as follows: After the equipment is started, the cam divider 202 drives the rotating plate 201 to rotate intermittently. When the clamping assembly 3 rotates to the assembly station 4, the operator or the automatic feeding device places the base plate 11 into the first positioning cavity 13, and places the clamping piece 12 along the feeding groove 31. The feeding cylinder 32 lifts and sends the clamping piece 12 to the horizontal position of the second positioning cavity 14. The first abutting block 304, driven by the second cylinder 305, presses and positions the base plate 11 and the clamping piece 12. At the same time, the connecting plate 15 is placed in the positioning groove 308 of the clamping block 302. The first cylinder 303 drives the clamping block 302 to clamp the connecting plate 15, and the second abutting block 306, driven by the third cylinder 307, abuts the connecting plate 15. After clamping is completed, the rotating plate 201 rotates 90 degrees, and the clamping assembly 3 enters the screwing station 5.

[0038] At the screwing station 5, the main push rod 42 drives the lifting slider 43 and the feeding clamp 403 downwards, so that the lower end of the feeding clamp 403 abuts against the clamping block 302. The auxiliary push rod 404 drives the drive motor 401 and the screwing head 402 downwards. The screwing head 402 screws the screw 16 in. The screw 16 passes through the guide hole 309, the slot of the base plate 11, and the threaded hole of the clamping piece 12 in sequence, and finally connects with the second connecting part of the connecting plate 15 by thread, completing the screwing. After the screwing is completed, all components are reset, the rotating plate 201 rotates 90 degrees again, and the clamping assembly 3 enters the riveting station 6.

[0039] At riveting station 6, the riveting machine 61 moves upward, and the lifting push rod drives the riveting seat 64 upward, driving the push rod 63 to push the pressure block 62 symmetrically towards the center, riveting the lower end of the screw 16 to complete the anti-loosening treatment. After riveting is completed, all components are reset, the rotating plate 201 rotates 90 degrees again, and the clamping assembly 3 enters the material handling station 7.

[0040] At the material handling station 7, the material handling cylinder 72 drives the material handling positioning component 73 to move downwards, the suction cup 74 picks up the assembled clamping piece assembly, and the linear module 71 drives the material handling positioning component 73 to move horizontally, transferring the finished product to the designated position. Subsequently, each clamping component 3 continues to circulate with the rotating plate 201, realizing continuous automated assembly operations.
