Description

Technical Field

[0001] This invention belongs to the field of headphone manufacturing, specifically a material handling robot for headphone production. Background Technology

[0002] The robotic loading and unloading device for headphone production uses mechanical, electrical, and control systems to automatically load and unload materials during headphone production. When processing the surface of the headphone shell, the robotic loading and unloading device is used to clamp the headphone shell from the storage box and place it on the processing area.

[0003] Existing technologies have also proposed some solutions. For example, a patent application with authorization announcement number CN206464459U discloses a CNC punching machine robot for earphone processing, which includes a loading mechanism, a supporting mechanism, a feeding mechanism, a gripping mechanism, and a receiving mechanism. This application saves manpower and improves efficiency by automatically loading and unloading materials.

[0004] While the above solution eliminates the need for manual loading and unloading of the earphone shell, the surface of the earphone shell is usually curved or slanted. If the suction cup is fixed in position and the earphone shell is curved or slanted, the suction cup may not be able to provide stable suction force in all positions when only the top of the earphone shell is suctioned.

The worm is fixed on a rotating shaft on one side of the outer deflector plate.

[0011] Preferably, the drive assembly further includes a side groove 1 formed on both sides inside the support column, a side rod 1 fixed inside the side groove 1, a movable block 1 sleeved on the outside of the side rod 1, the movable block 1 fixed on both sides of the rack, a spring 1 fixed on the top of the movable block 1, the spring 1 wrapped around the outside of the side rod 1, and the top of the spring 1 fixedly connected to the top end inside the side groove 1.

[0012] Preferably, the side clamping assembly includes a rotating column disposed above the connecting rod, the rotating column being rotatably disposed on both sides of the base plate, a side clamping plate being fixed to the top of the rotating column, a gear one being fixed on the rotating shafts on both sides of the rotating column, a gear two being disposed at the bottom of the gear one, and the gear two being fixed to the outside of the connecting rod.

[0013] Preferably, the side suction assembly includes a fixing groove formed in the side clamp, a support shell is provided inside the fixing groove, side round blocks are fixed on both sides inside the fixing groove, pivot pins are fixed on both sides of the support shell, the pivot pins are placed in the side round blocks, a coil spring is fixed outside the pivot pin, the outer side of the coil spring is fixedly connected to the inner wall of the side round block, a movable built-in block is provided inside the support shell, a side suction cup is installed at the bottom of the movable built-in block, a second side groove is formed on both sides inside the support shell, a second side rod is fixed inside the second side groove, a second movable block is sleeved outside the second side rod, the second movable block is fixed to both sides of the movable built-in block, a second spring is fixed to the top of the second movable block, the top of the second spring is fixedly connected to the top end inside the second side groove, and the second spring is wound around the outside of the second side rod.

[0014] Preferably, the pivot pin is rotatably disposed in the side circular block, and the support shell is rotatably disposed between the two side circular blocks via the pivot pin.

[0015] Preferably, the auxiliary tilting assembly includes a front shell fixed to the front of the support shell, a tilting rod is provided inside the front shell, a spring is fixed to the top of the tilting rod, the top of the spring is fixedly connected to the top of the front shell, and a roller is installed at the bottom of the tilting rod.

[0016] Preferably, the size of the tilting rod matches the size of the front housing, and the tilting rod can slide up and down in the front housing.

[0017] The beneficial effects of this invention are as follows: 1. The material handling device for headphone production described in this invention uses a side-mounted suction cup to gradually contact both sides of the headphone shell. Under the pressure of the side wall of the headphone shell, the side-mounted suction cup pushes a movable internal block into the support shell. When the movable internal block retracts into the support shell, it causes a second movable block to move upwards outside the second side rod and compress a second spring, causing it to contract. The second spring applies a reverse thrust to the second movable block, making the movable internal block tightly adhere to the side-mounted suction cup and the side wall of the headphone shell. If the side wall of the headphone shell is inclined or curved, the side-mounted suction cup, under the pressure of the side wall, will tilt the support shell, keeping the side-mounted suction cup perpendicular to the inclined or curved surface of the headphone shell, ensuring the suction cup adheres to the side wall of the headphone shell. The suction cup assembly, combined with the suction cup assembly, allows for the gripping of the headphone shell. The adhesion of the top and side walls of the headphone shell improves the gripping stability.

[0018] 2. The material handling robot for headphone production described in this invention, when the driving component gradually contacts the top of the headphone shell, gradually drives the outer deflector to rotate, causing the outer deflector located on both sides of the base plate to rotate and unfold outward, pushing the surrounding headphone shells outward, preventing the surrounding headphone shells from mixing with the headphone shells to be clamped, thus affecting the accuracy of headphone shell clamping. When the side clamping plate flips down to both sides of the headphone shell, the roller at the bottom of the tilting rod first contacts the side wall of the headphone shell. The roller and the tilting rod are acted upon by the tilted or curved side wall of the headphone shell, causing the side suction cup to tilt by driving the support shell to tilt. The side suction cup completes the tilting operation perpendicular to the side wall of the headphone shell before contacting it. When the side suction cup continues to contact the side wall of the headphone shell, the problem of difficulty in tilting the side suction cup due to the friction between it and the side wall of the headphone shell will not occur. This ensures that the side suction cup can more quickly become perpendicular to the tilted or curved side wall of the headphone shell and perform the adsorption operation.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 9 As shown, an embodiment of the present invention provides a material handling robot for headphone production, comprising a robot body 1, a base plate 2 disposed on the robot body 1, and a suction cup assembly 3 mounted on the bottom of the base plate 2. Both sides of the base plate 2 are provided with external push-out assemblies 5, the front and back of the base plate 2 are provided with driving assemblies 6, a side clamping assembly 4 is disposed between the external push-out assemblies 5, a side suction assembly 7 is disposed in the side clamping assembly 4, and an auxiliary tilting assembly 8 is disposed on the side suction assembly 7.

[0023] The surface of the earphone shell is usually curved or slanted. If the suction cup is fixed in position and the earphone shell is curved or slanted, the suction cup may not be able to provide a stable suction force in all positions when only the top of the earphone shell is attached. The robotic arm 1 moves the substrate 2 to the earphone shell to be gripped. The robotic arm 1 pushes the substrate 2 closer to the earphone shell. The suction cup assembly 3 at the bottom of the substrate 2 contacts the earphone shell. The suction cup assembly 3 is used to adsorb and grip the earphone shell. The robotic arm 1 moves the substrate 2 and the earphone shell adsorbed by the bottom suction cup assembly 3 to the processing area. The suction cup assembly 3 stops adsorbing the earphone shell and puts the earphone shell down. In this way, the loading and unloading operation of the earphone shell can be completed. When the substrate 2 moves to the earphone shell that needs to be clamped and clamps it, the substrate 2 gradually approaches the earphone shell. When the driving component 6 contacts the top of the earphone shell, the driving outward component 5 pushes the surrounding earphone shells outward to prevent the surrounding earphone shells from mixing with the earphone shell that needs to be clamped and affecting the accuracy of clamping the earphone shell. After the driving component 6 drives the external dial component 5 to dial around the earphone shell, it will drive the side clamp component 4 to move closer to the sides of the earphone shell. When the side suction component 7 moves to the sides of the earphone shell, the side suction component 7 contacts the side wall of the earphone shell. Under the pressure of the side wall of the earphone shell, the side suction component 7 tilts, so that the side suction component 7 fits against the earphone shell. The side suction component 7 adheres to the earphone shell. With the suction cup component 3 adhering to the earphone, the earphone shell can be clamped. The adsorption of the top and side wall of the earphone shell improves the clamping stability of the earphone shell. When the side suction component 7 moves to the position of the side wall of the earphone shell, the auxiliary tilt component 8 first contacts the earphone shell. The auxiliary tilt component 8 is used to tilt the side suction component 7 towards a position perpendicular to the side wall of the earphone shell. The auxiliary tilt component 8 is used to make the side suction component 7 tilt towards the side wall of the earphone shell and keep it perpendicular to the side wall of the earphone shell, thereby ensuring the suction effect of the side suction component 7.

[0024] like Figures 1 to 4 As shown, the outer deflector assembly 5 includes outer deflector plates 51 disposed on both sides of the base plate 2. Support seats 52 are disposed on both sides of the outer deflector plates 51. The support seats 52 are fixed on the two side walls of the base plate 2. A connecting rod 53 is fixed between the corresponding rotating shafts of the two outer deflector plates 51. The rotating shafts on both sides of the outer deflector plates 51 are rotatably disposed in the support seats 52. The outer deflector plates 51 are rotatably disposed between the two support seats 52.

[0025] The headphone shell storage box contains multiple headphone shells. When selecting a headphone shell for clamping, if other headphone shells are gathered around it, it will affect the accuracy of clamping. Therefore, as the base plate 2 gradually approaches the headphone shell to be clamped, the outer deflector plates 51 located on both sides of the base plate 2 are inserted into the other headphone shells. At this time, the headphone shell to be clamped is located between the outer deflector plates 51. As the drive component 6 gradually contacts the top of the headphone shell, the drive component 6 gradually drives the outer deflector plates 51 to rotate. The outer deflector plates 51 located on both sides of the base plate 2 rotate outward and unfold, pushing the surrounding headphone shells outward to prevent the surrounding headphone shells from mixing with the headphone shell to be clamped and affecting the accuracy of clamping the headphone shell.

[0026] like Figures 1 to 6 As shown, the drive assembly 6 includes a support column 61 fixed to the front and back of the base plate 2. A rack 62 is longitudinally arranged inside the support column 61. Gear 63 is rotatably arranged at the front and rear ends of the top of the base plate 2. One end of the gear 63 is placed in the support column 61 and meshes with the rack 62. Worm gears 64 are fixed on both sides of the gear 63. A worm 65 is meshed at the bottom of the worm gears 64. The worm 65 is fixed on a rotating shaft on one side of the outer deflector plate 51. The drive assembly 6 also includes a side groove 66 opened on both sides inside the support column 61. A side rod 67 is fixed inside the side groove 66. A movable block 69 is sleeved on the outside of the side rod 67. The movable block 69 is fixed on both sides of the rack 62. A spring 68 is fixed on the top of the movable block 69. The spring 68 is wound around the outside of the side rod 67. The top of the spring 68 is fixedly connected to the top end inside the side groove 66.

[0027] When the substrate 2 moves to the earphone shell to be clamped and is suction cup assembly 3 to clamp it, the substrate 2 gradually approaches the top of the earphone shell, and the rack 62 contacts the top of the earphone shell. As the substrate 2 moves down, the rack 62 moves up under the pressure of the earphone shell. The rack 62 drives the meshing gear 3 63 to rotate, the gear 3 63 drives the worm gear 64 to rotate, the worm gear 64 drives the bottom meshing worm 65 to rotate, and the rotating worm 65 drives the multiple outer deflector plates 51 connected by the connecting rod 53 to flip outward to perform an outward deflection operation on the surrounding earphone shell. At the same time, the rotating connecting rod 53 provides driving force for the side clamp assembly 4. When the rack 62 moves upward, causing the movable block 69 to slide upward outside the side rod 67, the movable block 69 compresses the spring 68 to retract. When the substrate 2 moves to the processing area and lowers the earphone shell, the suction cup assembly 3 stops adsorbing and gripping the earphone shell. The spring 68 loses pressure from the earphone shell and pushes the movable block 69 downward, causing the rack 62 to move downward. The rack 62 drives the gear 63 to rotate in the opposite direction, causing the worm gear 64 to rotate in the opposite direction. The worm gear 64 drives the worm 65 to rotate in the opposite direction. The worm 65, rotating in the opposite direction, first drives the side clamp assembly 4 to reset, and then causes the outer dial plate 51 to reset to a vertically downward position on both sides of the substrate 2. It should be noted that a rubber sleeve can be added to the bottom of the rack 62 to protect the earphone shell and prevent damage to the earphone shell caused by the pressure from the bottom of the rack 62.

[0028] like Figures 1 to 9 As shown, the side clamping assembly 4 includes a rotating column 42 disposed above the connecting rod 53. The rotating column 42 is rotatably disposed on both sides of the base plate 2. A side clamping plate 41 is fixed to the top of the rotating column 42. A gear 43 is fixed on the rotating shaft on both sides of the rotating column 42. A gear 44 is disposed at the bottom of the gear 43. The gear 44 is fixed to the outside of the connecting rod 53.

[0029] When the worm gear 65 drives the outer lever plate 51 to flip outward and flick the surrounding earphone shell, the connecting rod 53 drives the gear 2 44 to rotate, the gear 2 44 drives the gear 1 43 to rotate, and the gear 1 43 drives the side clamp plate 41 to flip downward through the rotating column 42. The side clamp plate 41 flips down to the two sides of the base plate 2 and is placed on the two sides of the earphone shell that need to be clamped, and works with the side suction assembly 7 to suction the two sides of the earphone shell. When the connecting rod 53 rotates in the opposite direction under the action of the worm gear 65, the second gear 44 drives the first gear 43 to rotate in the opposite direction. The first gear 43 causes the side clamp 41 to flip up and be removed from both sides of the earphone shell through the rotating column 42.

[0030] like Figures 1 to 9As shown, the side suction assembly 7 includes a fixing groove 71 formed in the side clamping plate 41. A support shell 72 is disposed inside the fixing groove 71. Side circular blocks 73 are fixed to both sides inside the fixing groove 71. Rotating pins 76 are fixed to both sides of the support shell 72, and the rotating pins 76 are placed in the side circular blocks 73. A coil spring 77 is fixed to the outside of the rotating pin 76, and the outer side of the coil spring 77 is fixedly connected to the inner wall of the side circular block 73. A movable built-in block 74 is disposed inside the support shell 72. A side suction cup 75 is installed at the bottom of the movable built-in block 74. The two sides inside the support shell 72... A side groove 78 is provided on the side, and a side rod 79 is fixed inside the side groove 78. A movable block 710 is sleeved on the outside of the side rod 79. The movable block 710 is fixed on both sides of the movable inner block 74. A spring 711 is fixed on the top of the movable block 710. The top of the spring 711 is fixedly connected to the top end inside the side groove 78. The spring 711 is wound around the outside of the side rod 79. A pivot pin 76 is rotatably set in the side circular block 73. The support shell 72 is rotatably set between the two side circular blocks 73 through the pivot pin 76.

[0031] When the side clamp 41 is flipped down and moved to the positions of the two sides of the earphone shell, the side suction cup 75 gradually contacts the two sides of the earphone shell. Under the pressure of the side wall of the earphone shell, the side suction cup 75 pushes the movable built-in block 74 into the support shell 72. When the movable built-in block 74 is retracted into the support shell 72, the movable built-in block 74 drives the movable block 710 to move upward outside the side rod 79 and squeeze the spring 711 to retract. The spring 711 applies a reverse thrust to the movable block 710, so that the movable built-in block 74 is in close contact with the side suction cup 75 and the side wall of the earphone shell. If the side wall of the earphone shell is a slope or a curved surface, the side suction cup 75 will tilt the support shell 72 under the pressure of the side wall of the earphone shell, so that the side suction cup 75 and the slope or curved surface of the earphone shell are perpendicular to each other, ensuring the adsorption effect of the side suction cup 75 on the side wall of the earphone shell. When the support shell 72 is tilted, it will cause the pivot pin 76 to rotate in the side block 73. The pivot pin 76 will cause the coil spring 77 to twist and deform. When the side suction cup 75 is not in contact with the earphone shell, the spring force of the coil spring 77 will drive the pivot pin 76 to rotate, so that the support shell 72 returns to the initial position. At the same time, the second spring 711 will also push the second movable block 710 to move the movable inner block 74 retracted into the support shell 72 out of the support shell 72.

[0032] like Figures 7 to 8 As shown, the auxiliary tilting assembly 8 includes a front housing 81 fixed to the front of the support housing 72. A tilting rod 82 is provided inside the front housing 81. A spring 83 is fixed to the top of the tilting rod 82. The top of the spring 83 is fixedly connected to the top of the front housing 81. A roller 84 is installed at the bottom of the tilting rod 82. The size of the tilting rod 82 matches the size of the front housing 81. The tilting rod 82 can slide up and down in the front housing 81.

[0033] When the side clamp 41 is flipped down to both sides of the earphone shell, the roller 84 at the bottom of the tilting rod 82 first contacts the side wall of the earphone shell. The roller 84 and the tilting rod 82 are acted upon by the tilted or curved side wall of the earphone shell, which causes the support shell 72 to tilt, thus tilting the side suction cup 75. The side suction cup 75 completes the tilting operation perpendicular to the side wall of the earphone shell before it contacts the side wall of the earphone shell. When the side suction cup 75 continues to contact the side wall of the earphone shell, the problem of the side suction cup 75 being difficult to tilt due to the friction between it and the side wall of the earphone shell will not occur. This ensures that the side suction cup 75 can be more quickly perpendicular to the tilted or curved side wall of the earphone shell and perform the suction operation. The roller 84 reduces the friction when the bottom of the tilt rod 82 directly contacts the earphone shell, allowing the support shell 72 to tilt more quickly via the tilt rod 82, reducing the impact of frictional resistance. As the side suction cup 75 gradually contacts and adheres to the earphone shell, the tilt rod 82 moves upward in the front shell 81, while simultaneously squeezing the spring 83 to retract it. After the side suction cup 75 stops adhering to the earphone shell and the side clamp 41 is removed from the side wall of the earphone shell, the tilt rod 82 moves downward under the elastic force of the spring 83 to return to its initial position.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
