Description

TECHNICAL FIELD

[0001] The utility model relates to a slide rail tipping robot chain automatic lubricating system. BACKGROUND

[0002] In the slide rail tipping robot system, the chain plate is the key component for the robot to move and position, and its running state directly affects the performance and service life of the robot. The lubrication of the chain plate is an important link to ensure its normal operation. The tipping platform of the slide rail tipping robot is installed on the Z-direction slide, and the Z-direction displacement chain serves as the key component and plays a role of suspension. In addition, there is no locking device, so the Z-direction chain bears the weight of the entire slide rail tipping robot and performs vertical movement, which is prone to failure and wear, especially requiring lubrication and maintenance.

[0003] However, there is no chain lubricating device for the slide rail tipping robot at present, which is prone to the failure of chain jamming and non-rotation caused by long-term use, so that the chain operation bears greater pressure, and once the limit is exceeded, the chain is prone to breakage, which causes the overall mechanism to fall and results in huge losses. The traditional lubrication method is manual application of lubricating oil, which is low in efficiency and difficult to ensure the uniformity and continuity of lubrication, and cannot meet the lubrication and maintenance requirements of the Z-direction chain.

[0011] The oil dripping support is arranged below the driving sprocket, and the distance is kept between the driving sprocket and the lifting chain vertically, the pipe segment between the butt joint pipe base and the oil dripping nozzle is arranged on the upper end of the oil dripping support.

[0012] The oil receiving box is a box structure with an open top, arranged below the driving sprocket, and the distance is kept between the driving sprocket and the lifting chain vertically, the open top is exposed and upwardly faces the oil dripping point.

Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0021] The chain includes outer chain plates with pin shafts, inner chain plates with sleeves, rollers, etc., and generally needs to add lubricating oil between the sleeve and the roller on the inner chain plate. If the lifting chain is operated for a long time in the absence of lubricating oil, the sleeve and the roller will be stuck and the gap will be too large. If the lifting chain has a large load, not only will there be abnormal noise during lifting, but also the gear of the speed reducer box of the motor of the chain wheel will be worn, and in severe cases, great loss will be caused. Therefore, it is necessary to add lubricating oil to the lifting chain at regular intervals.

[0022] Please refer to Figs. 1 to 3 The lifting chain 3 automatic lubricating system of the slide rail box turning robot is used for lubricating the lifting chain 3 of the slide rail box turning robot, and the lifting chain 3 is arranged between the upper driven sprocket 2 and the lower driving sprocket 1.

[0023] The automatic lubricating system is supplied with oil by the oil tank 4 with an oil pump 6, and the oil is supplied to the oil dripping nozzle 12 through the high-pressure oil pipe 7. The oil dripping nozzle 12 drips oil to the chain section of the lifting chain 3 running to the meshing position of the driving sprocket 1. The residual lubricating oil dripping from the lifting chain 3 at the oil dripping position is collected by the oil collecting box 13. The electromagnetic valve 8, the oil way distributor 9 and the flow regulating valve 10 are sequentially arranged on the high-pressure oil pipe 7 along the oil outlet direction.

[0025] The pipe section between the flow regulating valve 10 and the butt joint pipe seat 11 is a high-pressure nylon hose, and a sufficient length should be reserved to ensure that the movement of the slide robot relative to the oil dripping position is not limited.

[0026] The oil dripping nozzle 12 drips oil to the lowest position of the chain section of the lifting chain 3 running to the meshing position of the driving sprocket 1.

[0027] The oil dripping support 14 is arranged below the driving sprocket 1 and keeps a distance from the driving sprocket 1 and the lifting chain 3 vertically, the pipe base 11 is installed on the upper end of the oil dripping support 14 by means of the countersunk screw 15 and the pipe segment between the pipe base 11 and the oil dripping nozzle 12 by means of the metal buckles 16, so as to keep the position of the oil dripping nozzle 12 unchanged relative to the driving sprocket 1 and realize the fixed-point oil dripping.

[0028] The oil receiving box 13 is a box body structure with an open top, made of stainless steel, arranged below the driving sprocket 1 and keeping a distance from the driving sprocket 1 and the lifting chain 3 vertically, the open top is exposed and upwardly faces the fixed-point oil dripping position, the residual lubricating oil can be collected in time, the bottom of the slide can be kept clean, and the lubricating oil pollution can be avoided.

[0029] The oil dripping nozzle 12 horizontally suspends and presents a circular truncated cone shape, the small end is an outlet, perpendicular to the surface of the driving sprocket 1, closely opposite to the driving sprocket 1, and keeps a gap from the driving sprocket 1 along the direction parallel to the wheel shaft, closely adjacent to the lifting chain 3 below and keeping a gap vertically.

[0030] The oil dripping nozzle 12 can be made of high-performance flexible material, so that the dripping direction and angle of the oil dripping nozzle 12 can be adjusted arbitrarily, and the dripping lubricating oil can better penetrate between the sleeve and the roller of the chain below.

[0031] The high-pressure oil pipe 7 can be fixed on the nearest wall plate channel by means of a cable tie and a fixing buckle.

[0032] The PLC automatic control unit is arranged, the electromagnetic valve 8 and the oil pump 6 are connected to and controlled by the PLC automatic control unit, the dripping frequency of the automatic lubricating system is controlled by the electromagnetic valve 8 and the oil pump 6, and the fixed-time oil dripping is realized.
