Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

The invention provides a loading frame, as shown in fig. 1, the loading frame comprises a base 14, a buffer mechanism and a main frame 1 for loading a to-be-loaded object, the main frame 1 comprises a first supporting part 2 and a second supporting part 4 which are arranged in an included angle, the second supporting part 4 is transversely arranged and movably assembled on the base 14, and the buffer mechanism is arranged to be capable of preventing the second supporting part 4 from moving up and down relative to the base 14 so as to buffer the collision action between the second supporting part 4 and the base 14. The second support part 4 is arranged transversely, that is, the second support part 4 is arranged more inclined to the horizontal plane than to the vertical plane; specifically, the second support portion 4 may be disposed along the horizontal direction, that is, disposed on the horizontal plane, or the second support portion 4 may be disposed to extend obliquely from the horizontal direction, wherein a range of an inclined angle between the second support portion and the horizontal direction may be set to be smaller than 45 °. In addition, an arbitrary included angle may be set between the first supporting portion 2 and the second supporting portion 4, for example, in order to prevent the object to be carried from falling off and the like, so as to ensure the safe loading of the object to be carried (for example, a glass substrate), an included angle between the first supporting portion 2 and the second supporting portion 4 of the main frame 1 may be set to be 100 ° to 80 °, as shown in fig. 1, a supporting surface of the first supporting portion 2 for supporting the object to be carried is set to extend from the second supporting portion 4 toward a side away from the second supporting portion 4 in an inclined manner, and a supporting surface of the second supporting portion 4 for supporting the object to be carried is set to extend from the first supporting portion 2 in an.

Through the technical scheme, the loading frame is provided with the buffer mechanism, so that the relative movement between the second supporting part 4 and the base 14 is slower, the collision effect between the second supporting part 4 and the base 14 is buffered, the collision effect of the object to be loaded is effectively weakened, and the completeness of the object to be loaded is guaranteed. The main frame 1 and the base 14 may be made of various materials, for example, stainless steel.

Taking the glass substrate to be carried as an example, the glass substrate is placed on the main frame 1 of the loading frame, that is, the side portion of the glass substrate is supported by the first support portion 2 of the main frame 1, the bottom portion of the glass substrate is supported by the second support portion 4 of the main frame 1, when the glass base material is transferred along with the loading frame, particularly in the falling and placing process, the base 14 of the loading frame contacts the ground first and stops instantly, the main frame 1 still moves downwards integrally, at the moment, the buffer mechanism can block the relative movement between the second supporting part 4 and the base 14 of the main frame 1, that is, the buffer mechanism can slow down the overall downward movement speed of the main frame 1 to buffer the collision action between the second support part 4 and the base 14, and then effectively weakened the collision effect that second supporting part 4 transmitted the glass substrate, realized falling safely and put glass substrate to be favorable to glass substrate's safe transportation.

Further, the second supporting portion 4 and the base 14 are arranged at an interval, the buffering mechanism includes a flexible buffering member 26 (as shown in fig. 4) arranged between the second supporting portion 4 and the base 14, and the flexible buffering member 26 is arranged to obstruct the second supporting portion 4 from approaching the base 14 through deformation, so that the structure is simpler, the design is more reasonable, and the manufacturing and processing are facilitated.

When glass substrate transports along with the loading frame, especially in the in-process of putting that falls, after the base 14 of loading frame touched to earth and stopped, body frame 1 still moved down wholly, like this, flexible buffer 26 takes place compression deformation under the squeezing action of second supporting part 4 of body frame 1, and simultaneously, flexible buffer 26 can hinder second supporting part 4 of body frame 1 to move down fast because of the effort that compression deformation produced, namely, flexible buffer 26 can slow down the whole speed of moving down of body frame 1, namely, flexible buffer 26 hinders that second supporting part 4 of body frame 1 is close to base 14, has cushioned the collision effect between second supporting part 4 and base 14, thereby be favorable to glass substrate's safe transportation.

Further, as shown in fig. 1, fig. 2, fig. 4, fig. 6, fig. 8 and fig. 13, one of the base 14 and the second supporting portion 4 has a groove 16, the other has a protrusion 9, the protrusion 9 is movably embedded in the groove 16, the flexible buffer 26 is disposed in the groove 16 and respectively supports against the groove bottom wall of the groove 16 and the protrusion 9, so as to prevent the base 14 and the second supporting portion 4 from being dislocated or the flexible buffer 26 from falling off, thereby ensuring the stability of the overall structure of the loading rack and providing a strong guarantee for the safe transportation of the glass substrate. It should be noted that the flexible buffer 26 may be provided in various forms, for example, the flexible buffer 26 may be provided in various materials, for example, a clean memory material, a flexible rubber, a flexible resin, etc.; of course, the flexible buffer 26 may be provided in various shapes, such as a bar shape, a circular shape, etc.; preferably, the groove 16 is rectangular, and the protrusion 9 and the flexible buffer 26 are also correspondingly rectangular, so that the maximum design of the flexible buffer 26 is realized according to the structural characteristics of the second support part 4, and the buffering effect of the loading frame is optimized; further, as shown in fig. 4 and 13, in order to optimize the structural stability of the carrier, the groove side wall of the groove 16 has a plurality of ribs, and the protrusion 9 and the flexible buffer 26 are correspondingly provided with positioning grooves adapted to the ribs, so that the positioning between the base 14 and the second support 4 is more stable. It will be appreciated that the cross-sectional dimensions of the protrusion 9 and the flexible bumper 26 are slightly smaller than the cross-sectional dimensions of the groove 16 in order to allow the protrusion 9 to move relative to the groove 16 during the landing process.

Taking the base 14 with the groove 16 and the second support portion 4 with the protrusion 9 as an example for specific description, when the glass substrate is transferred along with the loading frame, especially during the dropping process, after the base 14 of the loading frame stops touching the ground, the groove 16 stops moving along with the glass substrate, the main frame 1 still moves down integrally, and the protrusion 9 moves down along with the glass substrate, so that the protrusion 9 moves down relative to the groove 16 continuously and presses the flexible buffer 26 to the compression deformation, and meanwhile, the acting force of the flexible buffer 26 generated by the compression deformation slows down the overall downward movement speed of the protrusion 9, thereby buffering the collision effect between the second support portion 4 and the base 14.

Further, as shown in fig. 1 and 2, the buffering mechanism includes a connecting member 27, and the connecting member 27 is configured to provide an elastic connection between the second supporting portion 4 and the base 14, so as to further optimize the structural stability of the loading frame, and provide a strong guarantee for the flexible buffer 26 to be reused, thereby ensuring the safe transportation of the glass substrate. Further, the carrier may include a plurality of connecting members 27 (e.g., 4), the plurality of connecting members 27 being spaced apart along the circumference of the base 14.

The connection member 27 may be in various forms, for example, the connection member 27 may include an elastic connection member (e.g., a spring, etc.) which is disposed between the second support portion 4 and the base 14 by compressive deformation and has two ends connected to the second support portion 4 and the base 14, respectively, and the connection member is simple in structure and convenient to manufacture and process. When the glass base material loading frame is used, when the glass base material is transferred along with the loading frame, particularly in the dropping process, after the base 14 of the loading frame stops touching the ground, the main frame 1 moves down integrally and extrudes the elastic connecting piece to generate compression deformation, and meanwhile, the acting force generated by the compression deformation of the elastic connecting piece slows down the integral downward moving speed of the main frame 1, so that the collision effect between the main frame 1 and the base 14 is further buffered.

The connecting rod 29 may be in various forms, for example, as shown in fig. 5, a bolt is used, and the stopping portions 30 at the two ends of the connecting rod 29 are respectively a head portion of the bolt and a nut screwed to the bolt.

If the first elastic member 28 (e.g., a spring, etc.) is disposed between the stopper 30 and the aperture outer end wall of the fitting hole 18 of the base 14 (i.e., the end wall of the second support portion 4 of the fitting hole 18) by compressive deformation, when the glass base material is transferred along with the carrier, particularly after the base 14 of the carrier stops touching the ground during the dropping process, the main frame 1 is still moved down as a whole in the extending direction of the connecting rod 29 and presses the first elastic member 28 for further compressive deformation, and at the same time, the force of the first elastic member 28 due to the further compressive deformation slows down the speed of the whole downward movement of the main frame 1, thereby further buffering the collision action between the main frame 1 and the base 14.

As shown in fig. 1 and 2, if the first elastic element 28 is disposed between the stopping portion 30 and the outer end wall of the opening of the mounting hole 8 of the second supporting portion 4 (i.e., the end wall of the mounting hole 8 away from the base 14) through compression deformation, when the glass substrate is transported along with the loading frame, particularly during the dropping process, after the base 14 of the loading frame stops touching the ground, and after the main frame 1 stops under the action of the deformation of the flexible buffer element 26, the flexible buffer element 26 will generally have a certain recovery deformation after the impact action of the main frame 1 is cancelled, which is as follows: when flexible buffering member 26 can take place to resume deformation, namely, the upper surface of flexible buffering member 26 upwards moves and drives the second supporting part 4 of body frame 1 and slowly shifts up along the extending direction of connecting rod 29 is whole, make second support frame 4 extrusion first elastic component 28 take place compression deformation, and simultaneously, first elastic component 28 slows down the whole upward moving speed of body frame 1 because of the effort that compression deformation produced, prevent that second support frame 4 of body frame 1 and backstop portion 30 of connecting rod 29 upper end from taking place violent collision, thereby realized the whole protection glass substrate of loading frame can be when transporting.
