Description

Technical Field

[0001] The utility model relates to the technical field of automation, in particular to a nozzle rotatable locking device. Background Technique

[0002] At present, the combined screws with square gaskets are applied to many products, such as terminal blocks, smoke alarms, etc. The existing automatic locking structure mainly uses a finger cylinder to clamp the gasket first, and then the bit pierces down from the middle for locking. It does not have a rotation function, so it can only lock the gasket on products at a fixed angle and cannot meet the requirements of products with multiple angles and small space. At the same time, when locking, the clamping piece of the finger cylinder will rub against the gasket, scraping off the plating layer on the gasket, which may cause the gasket to rust and thus affect the quality of the product.

[0022] The following will combine the attached drawings and specific embodiments to elaborate on the present utility model in detail.

[0023] Referring to Figures 1 to 2 as shown, the present utility model provides a lock attachment device with a rotatable suction nozzle. In one embodiment, it includes

[0024] a fixed vertical plate 1, and a fixed horizontal plate 2 is connected to the lower part of one side of the fixed vertical plate 1; a first lifting mechanism 3 is further installed on the fixed vertical plate 1, and the first lifting mechanism 3 also drives and connects a first lifting seat 4; an electric screwdriver 5 is installed on the first lifting seat 4, and the electric screwdriver 5 is also detachably connected with a bit head 51;

[0025] a rotating sleeve 6, a first bearing is installed on the fixed horizontal plate 2, the rotating sleeve 6 is arranged below the fixed horizontal plate 2, and one end of the rotating sleeve 6 is connected to the first bearing; a vacuum suction nozzle 7 is installed at the other end of the rotating sleeve 6, and an air source connector 71 for accessing an external air source is further provided on the vacuum suction nozzle 7; one end of the bit head 51 passes through the rotating sleeve 6 movably and is movably inserted into the vacuum suction nozzle 7 for arrangement;

[0026] a rotation driving mechanism 8 connected to the rotating sleeve 6 is further installed on the fixed horizontal plate 2, and the rotation driving mechanism 8 is used to drive the rotating sleeve 6 to drive the vacuum suction nozzle 7 to rotate.

[0027] Continuing to refer to Figures 1 to 2 as shown, in this embodiment, a bottom plate 9 is further connected to the lower part of one side of the fixed vertical plate 1, the bottom plate 9 is located below the fixed horizontal plate 2, a second bearing is further installed on the bottom plate 9, and the middle part of the rotating sleeve 6 is connected to the second bearing. By providing the first bearing and the second bearing, the rotation stability of the rotating sleeve 6 can be improved.

[0028] During operation, first, the external three-axis translation mechanism drives the device to move to the screw-taking position. The air source connector 71 is connected to an external negative-pressure air source, and the screw is sucked up by the vacuum nozzle 7. Then, it moves above the screw hole of the product. Subsequently, the rotation drive mechanism 8 drives the rotating sleeve 6 to drive the vacuum nozzle 7 to rotate to a specified angle. Then, the first lifting mechanism 3 drives the electric screwdriver 5 to descend, presses the screw (in this embodiment, a combined screw with a square gasket) into the screw hole position. Subsequently, the electric screwdriver 5 starts and locks the screw onto the product. Finally, the electric screwdriver 5 stops, the bit 51 retracts, and then the above steps are repeated to continue locking the next screw.

[0029] In addition, a first bayonet 72 with an L-shaped structure is also opened at the bottom of the vacuum nozzle 7. In this embodiment, the screw is equipped with a square gasket. When sucking and locking the screw, the square gasket can be limited by the first bayonet 72 with a right-angle structure to prevent the gasket from rotating during the process of locking the screw.

[0030] In one embodiment, the rotation drive mechanism 8 includes a first rotation motor 81 installed on the fixed cross plate 2, a driving wheel 82 connected to the output shaft of the first rotation motor 81, a driven wheel 83 installed on the rotating sleeve 6, and a synchronous belt 84 wound between the driving wheel 82 and the driven wheel 83. The first rotation motor 81 is a stepping motor. Driven by the first rotation motor 81, the rotating sleeve 6 can be driven to rotate relative to the bearing through the driving wheel 82, the synchronous belt 84, and the driven wheel 83, thereby adjusting the angle of the screw sucked by the vacuum nozzle 7. At the same time, an annular induction piece 85 is also installed on the driven wheel 83; a groove-type photoelectric sensor 86 cooperating with the induction piece 85 is installed on the fixed cross plate 2. Through the induction piece 85 and the groove-type photoelectric sensor 86, the background can monitor the position and state of the rotating sleeve 6 to accurately control the rotation angle of the rotating sleeve 6.

[0032] In this embodiment, the first lifting cylinder 32 is a pen-shaped cylinder. Driven by the first lifting cylinder 32, the first lifting seat 4 can be driven to drive the electric screwdriver 5 to lift and lower, so as to lock the screws. At the same time, the first connecting block 34 has an L-shaped structure. The L-shaped vertical end of the first connecting block 34 is connected to one side of the first lifting seat 4, and the L-shaped horizontal end of the first connecting block 34 is movably sleeved on the first connecting rod 33; a limiting step is further provided on the upper part of the first connecting rod 33, and a limiting block 35 is further connected to the bottom of the first connecting rod 33; a buffer spring is further sleeved on the outer wall of the first connecting rod 33, and the two ends of the buffer spring are respectively abutted against the bottom of the limiting step and the top of the L-shaped horizontal end of the first connecting block 34. The upward reaction force generated by the product on the electric screwdriver 5 can be buffered by the buffer spring, avoiding damage to the product.

[0033] In addition, a first buffer 12 is installed above the L-shaped vertical end of the first connecting block 34 on the first connecting plate 31; a first fixing block is further connected to the fixed vertical plate 1, and the first fixing block is located below the L-shaped horizontal end of the first connecting block 34; a second buffer 13 is further installed on the first fixing block. By means of the first buffer 12 and the second buffer 13, the lifting stroke of the electric screwdriver 5 can be limited, avoiding excessive lifting.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
