Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to an origin finding mechanism for the lower suction cup of a polishing machine. Background Art

[0002] With the continuous development and progress of social science and technology, glass has become the most common item in daily life. From the glass windows on buildings to the windshield glass on cars, and down to the screens on mobile phones, etc., glass needs to be polished before leaving the factory. By polishing the matte surface and edge parts of the glass, it can meet the usage requirements before leaving the factory.

[0003] At present, most of the existing polishing machines on the market are manually loaded and unloaded. Workers place the glass on the carrier table, then adsorb and fix the glass, and then process it with the grinding disc above. After the glass is processed, workers lift and unload the glass from the carrier table. However, since glass is a fragile object, lifting or handling it manually easily causes the glass to break, which is not conducive to the unloading of the glass.

[0004] Therefore, a manipulator was invented to assist in unloading. The suction cup manipulator adsorbs on the upper surface of the glass, enabling the glass to be evenly stressed when being lifted and lowered, reducing the manual labor intensity, ensuring the safety during the glass transfer process, and improving the production efficiency. However, when the manipulator picks up and places the glass, the carrier table needs to be at the origin position to facilitate the manipulator to quickly and accurately pick up and place the glass. However, after the carrier table stops rotating, it cannot accurately return to the origin position and needs to be adjusted manually, and then the manipulator is used to pick up and place the glass, making the loading and unloading process cumbersome and time-consuming, and unable to achieve automated production processing.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Content of the Utility Model

[0006] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present utility model is to provide an origin finding mechanism for the lower suction cup of a polishing machine.

[0007] To achieve the above purpose, the present utility model adopts the following technical solutions:

A lower suction cup, a driving mechanism, a positioning disc, and a lifting and positioning mechanism are arranged on the machine table. The positioning disc is located directly below the lower suction cup. The driving mechanism is arranged between the lower suction cup and the positioning disc, and the driving mechanism synchronously controls the lower suction cup and the positioning disc to rotate. The lifting and positioning mechanism is arranged on one side of the lower end of the positioning disc and moves upward to lift the positioning disc to complete origin finding.

[0009] As a preference, the driving mechanism includes a driving motor and a speed reducer. The driving motor extends rotating shafts towards both the upper and lower ends. The rotating shaft at the upper end of the driving motor is connected to the lower suction cup and controls its rotation. The rotating shaft at the lower end of the driving motor extends into the speed reducer, and the speed reducer has a rotating shaft that extends downward and is connected to control the rotation of the positioning disk.

[0010] As a preference, a bearing support assembly is further provided at the lower end of the positioning disk. The bearing support assembly consists of a support frame and a bearing. The lower end of the support frame is fixedly installed on the lower inner end face of the machine table, and the bearing is vertically installed at the upper end of the support frame, with the outer wall of the bearing abutted against the lower end face of the positioning disk in an active manner.

[0011] As a preference, the number of the bearing support assemblies is set to be plural, and the plural bearing support assemblies are distributed in a circumferential array.

[0012] As a preference, the lifting and positioning mechanism includes a positioning bracket and a lifting cylinder. The lower end of the positioning bracket is fixedly installed on the lower inner end face of the machine table, the lifting cylinder is fixed at the upper end of the positioning bracket, the lifting cylinder is arranged in a vertical state and extends an upward piston rod, and the top end of the piston rod extends into the positioning disk.

[0013] As a preference, a positioning hole is provided on the positioning disk. The position of the positioning hole is set to be the same as the position of the piston rod for accurate positioning, and the size of the positioning hole is adapted to the size of the piston rod, so that the piston rod can accurately extend into the positioning hole to quickly complete the origin finding by positioning.

[0014] As a preference, a sensor assembly is further provided at the outer side end of the positioning disk. The sensor assembly includes a counting sensor, a speed measuring sensor, a position sensor and a fixing bracket. The counting sensor, the speed measuring sensor and the position sensor are all installed at the upper end of the fixing bracket. The lower end of the fixing bracket is fixedly installed on the lower inner end face of the machine table and is located at the outer side end of the positioning disk. The sensor assembly is used to detect the number of rotation circles, the rotation speed and the stopped position information of the positioning disk, and upload the data signal, so that the positioning disk can accurately rotate back to the origin position.

[0015] As a preference, a horizontally arranged transverse air duct and several longitudinally arranged longitudinal air ducts are provided at the middle end of the lower suction cup. The several longitudinal air ducts are arranged on both sides of the transverse air duct. One end of the longitudinal air duct is communicated with the transverse air duct, and the other end extends out of the outer side face of the lower suction cup. Several suction holes distributed in an array are provided on the upper end face of the lower suction cup, and the suction holes extend downward from the upper end face of the lower suction cup to the longitudinal air duct and the transverse air duct.

It analyzes data by receiving the detection and induction signals uploaded by the sensor assembly, and issues control instructions to the driving mechanism and the lifting and positioning mechanism, so that the positioning plate and the lower suction cup can return to the origin position. Then, the lifting and positioning mechanism is used to limit and fix the positioning plate, and then a control instruction is issued to the vacuum device to release / activate the vacuum adsorption state of the lower suction cup, so that the glass can be firmly adsorbed / loosened from the end face of the lower suction cup.

[0018] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

By arranging a positioning plate below the lower suction cup, the positioning plate can rotate together with the lower suction cup, and a positioning mechanism is further arranged at the lower end of the positioning plate, so that the positioning mechanism can accurately position the positioning plate, so that the upper lower suction cup can quickly find the origin position, facilitating the adsorption manipulator to quickly and accurately pick and place the glass, improving the origin finding effect of the equipment, ensuring that the picking and placing positions of the glass are the same, reducing the workload of workers, realizing automatic production, improving production efficiency, and reducing the production cost of the enterprise.

[0020] The lower suction cup is also improved. By arranging a transverse air passage and multiple groups of longitudinal air passages in the lower suction cup, and arranging suction holes extending downward to the air passages on the lower suction cup, the air between the suction holes and the glass can be evacuated or injected with air to break the vacuum along the air passages, so that the lower suction cup can quickly and stably adsorb the glass, or the gas can be blown upward, so that the glass can be smoothly taken away by the adsorption manipulator. An air inlet pipe is provided between the vacuum device and the lower suction cup, and the air inlet pipe passes through the driving mechanism and is connected to the lower suction cup, thus forming a complete vacuum suction state.
