Description

Technical Field

[0001] The invention relates to the technical field of sponge buckle processing equipment, and in particular to an automatic assembly equipment for sponge buckles of a sitting chair. Background Art

[0002] In the process of using the sitting chair, in order to effectively fix the sponge on the frame of the sitting chair and prevent the sponge from shifting or falling off due to gravity, user movements or external factors in daily use, a buckle is often used to effectively fix the sponge. The sponge buckle is tightly connected to the frame, which also provides additional stability for the overall structure of the sitting chair, which helps to ensure that the sitting chair is not easy to shake or tip over during use, further improving the user experience;

[0003] During the assembly process of sponge buckles, the raw materials are automatically transported from the warehouse to the designated position of the production line by an automatic loading mechanism, and then the assembly parts are placed at the predetermined position. According to the characteristics and assembly requirements of the sponge buckles, the sponge buckles are automatically assembled. After assembly, the complete sponge buckles are transported to the finished product warehouse by a conveying mechanism. However, in actual operation, the component picking mechanism or the assembly mechanism often causes the sponge buckles to be assembled inaccurately (the buckles are easy to loosen or fall off by themselves) or misaligned due to improper program settings. Improper program settings are mainly manifested in the following aspects: such as unreasonable assembly path planning, too fast or too slow assembly speed, etc. For this reason, we propose an automatic assembly equipment for sponge buckles of sitting chairs.

It should be noted that the conveying mechanism 3 equipped with a plurality of connecting brackets 4 is a conveying unit for conveying a buckle support portion 31 and assembling the buckle, and a connecting frame 41 is fixedly installed on the connecting bracket 4, and a moving portion 42 is arranged inside the connecting frame 41, and a telescopic portion 43 is fixedly installed on the moving portion 42, and an elastic portion 44 for applying a force to the buckle clamping portion 32 is arranged on the telescopic portion 43, and the elastic portion 44 includes a rubber action panel 444 arranged above the telescopic portion 43, and the rubber action panel 444 is connected to the surface of the telescopic portion 43 with a buffer spring 442, wherein the rubber action panel 444 is fixedly installed There are multiple guide shafts 443, and each guide shaft 443 is slidably connected to the surface of the telescopic part 43; as a further limitation in the present invention, the moving part 42 includes a moving sleeve 423 arranged inside the connecting frame 41, wherein the moving sleeve 423 is slidably connected to the inner wall of the connecting frame 41, and multiple constant force springs 424 are connected between the moving sleeve 423 and the side wall of the connecting frame 41, and a force-bearing rod frame 425 slidably connected to the inner wall of the moving sleeve 423 is installed inside the moving sleeve 423, wherein the force-bearing rod frame 425 is located on the motion trajectory of the buckle support part 31, and a limiting panel 411 is fixedly installed on the top of the connecting frame 41, and the limiting panel 411 is provided There is an inclined through groove 412, and a sliding telescopic shaft 431 is fixedly installed on the telescopic part 43, and the sliding telescopic shaft 431 slides within the inclined through groove 412. An extension rod frame 421 is fixedly installed on the force-bearing rod frame 425, and two sensing elements 422 are also parallelly installed on the top inner wall of the extension rod frame 421, and there is a height difference between the two sensing elements 422. A trigger rod frame 441 is fixedly installed on the elastic part 44, and each sensing element 422 is located on the movement trajectory of the trigger rod frame 441; a silicone sleeve 429 is fixedly installed on the end of the force-bearing rod frame 425, and a reset spring 426 is also connected between the force-bearing rod frame 425 and the inner wall of the movable sleeve 423.

[0034] A telescopic movable shaft 427 is symmetrically installed on the force-bearing rod frame 425, and a limiting groove 428 is symmetrically arranged on the movable sleeve 423, and the telescopic movable shaft 427 slides in a limited position in the limiting groove 428, wherein an adjustment groove 413 is arranged on the inner wall of the connecting frame 41, and the end of the telescopic movable shaft 427 slides in a limited position in the adjustment groove 413, and the adjustment groove 413 in the present invention includes a force-bearing sliding area 414, an inclined departure area 415 connected to the force-bearing sliding area 414, a sliding reciprocating area 416 connected to the inclined departure area 415, and an inclined reciprocating area 417 respectively connected to the force-bearing sliding area 414 and the sliding reciprocating area 416, wherein a guide panel 418 is fixedly installed at the intersection of the sliding reciprocating area 416 and the inclined departure area 415, and the guide panel 418 is an inclined surface on the side of the inclined departure area 415 and a right-angle surface on the side of the sliding reciprocating area 416.

[0035] Specific, combined Figure 2-Figure 4 As shown, in the initial state of the force-bearing rod frame 425 of the present invention, on the movement trajectory of the buckle support part 31, the rubber action panel 444 is close to the surface of the buckle clamping part 32, and then in the actual working process, the buckle support part 31 touches the force-bearing rod frame 425 during the movement with the conveying mechanism 3, and then the force-bearing rod frame 425 is subjected to the force to drive the movable sleeve 423 to perform directional movement, and the movable sleeve 423 stretches the constant force spring 424 during the movement, and at the same time, the telescopic movable shaft 427 on the force-bearing rod frame 425 will move along the trajectory of the adjustment slot 413; combined with the attached Figure 8 As shown, in the initial state, the telescopic movable shaft 427 is located at the initial end of the force-bearing sliding area 414. After being acted upon by the buckle support portion 31, the telescopic movable shaft 427 on the force-bearing rod frame 425 moves along the trajectory of the force-bearing sliding area 414 (and moves toward the end of the inclined departure area 415). Figure 3 and attached Figure 4 As shown, at this time, the sliding telescopic shaft 431 on the telescopic part 43 will move along the track of the inclined through-slot 412, and then the telescopic part 43 will squeeze the buffer spring 442, and the buffer spring 442 will act on the rubber action panel 444. At this time, there are three situations:

[0036] Case 1: The buckle support portion 31 and the buckle engaging portion 32 are completely assembled, and the rubber action panel 444 is subjected to the force of the buffer spring 442 to apply force to the buckle engaging portion 32. Since the buckle is completely assembled, the rubber action panel 444 is blocked, the buffer spring 442 is in a compressed state, and the trigger rod frame 441 on the rubber action panel 444 does not move, and the sensing element 422 is not triggered.

[0037] Case 2: The buckle support part 31 and the buckle clamping part 32 are not fully assembled, and the rubber action panel 444 is subjected to the force of the buffer spring 442 to apply a force to the buckle clamping part 32. Since the buckle is not fully assembled, the buckle clamping part 32 is separated from the buckle support part 31 by the force of the rubber action panel 444. It should be noted that the separation means that the buckle clamping part 32 is displaced on the buckle support part 31 but does not fall off, that is, there is an improper assembly condition between the buckle support part 31 and the buckle clamping part 32. At the same time, the trigger rod frame 441 on the rubber action panel 444 will move with the rubber action panel 444, and then one of the sensing elements 422 relatively close to the rubber action panel 444 will be triggered;

[0038] Case 3: The buckle support portion 31 and the buckle engaging portion 32 are misaligned, that is, the buckle engaging portion 32 is not installed on the buckle support portion 31, and the buckle engaging portion 32 may be placed by the picking mechanism 101 in the vicinity of the buckle support portion 31 (also on the conveying mechanism 3), and the rubber action panel 444 moves upward under the action of the buffer spring 442. Since the buckle engaging portion 32 is not installed on the buckle support portion 31, the rubber action panel 444 will not be hindered by the action force, and the trigger rod frame 441 on the rubber action panel 444 will trigger the two sensing elements 422;

[0039] The above is a specific implementation method corresponding to each component when the telescopic movable shaft body 427 is located in the force-bearing sliding area 414 and the inclined departure area 415. When the telescopic movable shaft body 427 moves to the inclined departure area 415, the force-bearing rod frame 425 will move toward the inside of the movable sleeve 423 and squeeze the return spring 426. When the telescopic movable shaft body 427 enters the sliding reciprocating area 416 from the inclined departure area 415, the force-bearing rod frame 425 is not on the movement trajectory of the buckle support portion 31, and then the movable sleeve 423 moves in the opposite direction under the action of the constant force spring 424, and the force-bearing rod frame 425 will also be subjected to the action force. The telescopic movable shaft body 427 will move along the trajectory of the sliding reciprocating area 416 under the above two actions, and finally move along the inclined reciprocating area 417 to the initial end of the force-bearing sliding area 414. At this time, the force-bearing rod frame 425 returns to the initial position and is subjected to the action of the next buckle support portion 31.

[0040] In order to assemble the incompletely assembled or misplaced buckles, the present invention is designed as follows: a support frame 5 is also fixedly installed on the platform 1, and a connecting plate frame 51 is arranged on one side of the support frame 5, and the connecting plate frame 51 is connected to the support frame 5 by a power unit, and the power unit can use a power source such as a hydraulic cylinder, a servo motor unit, and a moving frame 52 is arranged inside the connecting plate frame 51, and a cylinder 53 is fixedly installed on the connecting plate frame 51, and the output end of the cylinder 53 passes through the top of the connecting plate frame 51 and is fixedly connected to the top of the moving frame 52; a rotating sleeve 54 rotatably connected to the moving frame 52 is installed at the bottom of the moving frame 52, and a rigid plate frame 55 is fixedly installed on the end of the rotating sleeve 54, a suction cup unit 56 is fixedly installed on one end of the rigid plate frame 55, and a pressing unit 57 is fixedly installed on the other end of the rigid plate frame 55, as shown in the attached Fig. 9 As shown, a rigid shaft 58 is arranged inside the rotating sleeve 54, and the end of the rigid shaft 58 passes through the bottom of the moving frame 52 and extends into the inside thereof, a limited shaft 521 is fixedly installed inside the moving frame 52, and a magnetic plate frame 581 is installed on the top of the rigid shaft 58, and the magnetic plate frame 581 slides within the limited limit on the rigid shaft 58, a spring mechanism 59 is connected between the inner wall of the bottom of the moving frame 52 and the magnetic plate frame 581, and the spring mechanism 59 is sleeved on the limited shaft 521, wherein an electric magnet 50 is fixedly installed on the top of the inner wall of the moving frame 52, and the electric magnet 50 is electrically connected to the induction element 422, and the electric magnet 50 generates a repulsive force on the magnetic plate frame 581 when energized, a spiral groove 582 is arranged on the outer wall of the rigid shaft 58, and a rolling ball 541 is installed on the inner wall of the rotating sleeve 54, and the rolling ball 541 slides within the limited limit in the spiral groove 582.

[0041] Combination Fig. 9 and Fig.10 As shown, in the initial state, the pressing unit 57 is located directly above the conveying mechanism 3 (see Fig. 9 The suction cup unit 56 is shown to be located directly above the conveying mechanism, i.e., not in the initial state). When the first sensing element 422 is triggered, the power unit controls the connecting plate frame 51 to adjust the position so that the pressing unit 57 is located directly above the buckle that is not fully assembled. Then, the cylinder 53 is started to make the moving frame 52 descend, so that the pressing unit 57 acts on the buckle that is not fully assembled by rotating the sleeve 54 and the rigid plate frame 55, so as to ensure that the buckle is fully assembled.

[0042] When the second sensing element 422 is triggered, it indicates that the buckle support portion 31 and the buckle engaging portion 32 are misaligned, and the electric magnet 50 is energized to generate a repulsive force on the magnetic plate frame 581, so that the rigid shaft 58 descends, and the magnetic plate frame 581 squeezes the spring mechanism 59. During the descent of the rigid shaft 58, the spiral groove 582 thereon acts on the rolling ball 541 to rotate the rotating sleeve 54, and the rotation angle is 180°. At this time, the suction cup unit 56 is located directly above the conveying mechanism 3 and generates an attraction for the components on the conveying mechanism 3. Since the buckle support portion 31 is limited by the conveying mechanism 3, it will not be attracted by the suction cup unit 56, and the misaligned buckle engaging portion 32 will be attracted by the suction cup unit 56 on the conveying mechanism 3, and then the cylinder 53 uses the above-mentioned components to enable the suction cup unit 56 to control the height adjustment of the buckle engaging part 32, and move it to the buckle supporting part 31 under the action of the power unit. When the power unit adjusts the position of the buckle supporting part 31, the suction cup unit can be moved to the buckle supporting part 31 under the action of the power unit through the corresponding electronic control unit. The suction cup unit 56 stops ventilating, and the buckle engaging part 32 is on the buckle supporting part 31. Then the electric magnet 50 is powered off, and the pressing unit 57 is returned to the top of the buckle supporting part 31 under the action of the spring mechanism 59. Under the action of the cylinder 53, the movable frame 52 is lowered, so that the pressing unit 57 acts on the buckle that is not fully assembled by rotating the sleeve 54 and the rigid plate frame 55 to ensure that the buckle is fully assembled.
