As shown in fig. 7 to 9, the rotating device of the present invention includes a frame 101, a water pan 102, a turntable 103, a jig 104, a pawl 105, a torsion spring 106, a pawl cylinder 107, a pawl cylinder seat 108, a rotating pin 109, a swing arm 110, a rotating shaft 111, a ratchet wheel 112, a positioning cylinder 113, a positioner assembly 114, a rotating shaft seat 115, and an upper support 116. In addition, it should be noted that a is a loading and unloading station, B is a first polishing station, C is a second polishing station, D is a third polishing station, E is a fourth polishing station, F is a water washing station, G is a drying station, H is a glass storage position of the jig 104, and I is a positioning pin hole on the rotating shaft 111.
In order to stabilize the rotation of the turntable 103, the rotation device preferably includes a rotation shaft 111 and a rotation shaft seat 115; the rotary shaft seat 115 is fixedly arranged on the external frame 101, the rotary shaft 111 is arranged on the rotary shaft seat 115 and can rotate around the axis of the rotary shaft, one end of the rotary shaft 111 is connected with the turntable 103, and the other end of the rotary shaft is connected with the rotary driving piece. In the preferred embodiment of the present invention, as shown in fig. 7 to 9, the rotating shaft 111, the rotating shaft seat 115 and the turntable 103 are all designed to be circular, but in other embodiments, the rotating shaft 111, the rotating shaft seat 115 and the turntable 103 may be designed to be other shapes as long as the turntable 103 can rotate around its center.
In the case where the positions of the respective stations have been determined, the moving direction of the glass-carrying jig 104 should be fixed, for example, in the embodiment of fig. 7, the glass-carrying jig 104 is moved in the direction from station a to station G and cannot be moved in the direction from station G to station a. Therefore, in order to ensure that the moving direction of the jig 104 is fixed, it is preferable that the rotary driving member includes a unidirectional rotation unit connected to the rotating shaft 111 to define the rotating direction of the rotating shaft 111.
It should be understood that the unidirectional rotation unit may be designed in various structures, for example, a unidirectional motor, as long as the rotation direction of the rotation shaft 111 can be ensured to be unchanged, and in the preferred embodiment of the present invention, the unidirectional rotation unit includes the pawl 105, the torsion spring 106, the pawl cylinder 107, the rotation pin 109, the swing arm 110, and the ratchet wheel 112; the ratchet wheel 112 is coaxially and fixedly arranged on the rotating shaft 111; the pawl cylinder 107 is hinged with one end of a swing arm 110 through a rotating pin 109, and the other end of the swing arm 110 is connected with a rotating shaft 111 and can rotate around the rotating shaft 111; the pawl 105 is disposed on the swing arm 110 and rests against the ratchet wheel 112 via the torsion spring 106. That is, in the initial state, pawl 105 abuts against the tooth portion of ratchet wheel 112 under the pressure of torsion spring 106, and when rotation shaft 111 is rotated as needed, the piston rod of pawl cylinder 107 is retracted so that pawl 105 follows the tooth portion of ratchet wheel 112 by one tooth, and then the piston rod of pawl cylinder 107 is extended to push swing arm 110 to rotate, thereby bringing pawl 105 forward to drive rotation shaft 111 to rotate.
In order to make the pawls 105 rotate by just the angle of the rotating shaft 111 every time the pawls drive, the jig 104 can enter the next station, and preferably, the number of the jig 104 corresponds to the number of the teeth of the ratchet wheel 112. That is, the piston rod of the ratchet cylinder 107 just moves the jig 104 on the turntable 103 to the next station after each retraction and extension action. It should be understood that the number of teeth of ratchet wheel 112 may be designed to be several times the number of jigs 104, for example, when the number of teeth of ratchet wheel 112 is 5 times the number of jigs 104, the piston rod of pawl cylinder 107 is retracted to make pawl 105 back five teeth along the teeth of ratchet wheel 112, which ensures that the piston rod of pawl cylinder 107 is extended to move jigs 104 on turntable 103 to the next station.
In actual operation, the action of the ratchet wheel 112 and the pawl 105 may cause rotation error of the rotating shaft 111, and in order to prevent this problem phenomenon, the rotating shaft 111 is preferably provided with a positioning pin hole I; the positioning mechanism comprises a positioning cylinder 113 and a positioner assembly 114; the positioner assembly 114 includes a cylindrical pin connected to the piston rod of the positioning cylinder 113 to extend into or disengage from the positioning pin hole I upon actuation of the positioning cylinder 113.
The working process of the positioning mechanism and the unidirectional rotation unit is explained below by taking the preferred embodiment of the present invention as an example: as shown in fig. 9, in the initial state, the pawl 105 is pressed against the toothed portion of the ratchet wheel 112 by the torsion spring 106, the cylindrical pin on the positioner assembly 114 is inserted into the positioning pin hole I, the pawl cylinder 107 and the positioning cylinder 113 are both in the extended state, and each jig 104 on the turntable 103 is in the working position. When tool 104 is required to enter the next station, the piston rod of pawl cylinder 107 is retracted and pawl 105 can only back up one tooth along the teeth of ratchet wheel 112 because rotating shaft 111 is still locked by the cylindrical pin of positioner assembly 114. Immediately after the positioning cylinder 113 is retracted, the cylindrical pin of the positioner assembly 114 is withdrawn from the positioning pin hole I, so that the rotary shaft 111 can rotate freely. Then the piston rod of the pawl cylinder 107 extends out to push the swing arm 110 to rotate so as to drive the pawl 105 to drive the rotating shaft 111 and the turntable 103 forward to rotate for one station, and then the cylindrical pin of the positioner assembly 114 is inserted into the positioning pin hole I again under the action of the positioning cylinder 113 to lock the rotating shaft 111 again, so that the jig 104 enters the next station and is locked. The above steps are repeated, so that each jig 104 on the turntable 103 passes through all the stations.
In order to prevent the positioner assembly 114 from rotating along with the rotating shaft 111, it is preferable that the positioner assembly 114 includes a seat cover fixedly disposed on the frame 101, the seat cover is provided with a cylindrical pin hole for the cylindrical pin to move, and the positioning cylinder 113 is disposed on the seat cover.
It should be understood that a plurality of locator assemblies 114 may be provided at intervals in the circumferential direction of the rotating shaft 111 so that the locator pin holes I can be located by the cylindrical pins of one locator assembly 114 when going to the next station, and in a preferred embodiment of the present invention, in order to optimize the structural composition and reduce the cost, in the case where the number of the jig 104 corresponds to the number of the teeth of the ratchet wheel 112, the rotating shaft 111 is provided at intervals in the circumferential direction, and the number of the locator pin holes I corresponds to the number of the teeth of the ratchet wheel 112. It should be understood that the number of registration pin holes I should correspond to the number of jigs 104 in order to ensure that the jig 104 is positioned each time it reaches the next station.
