Description

Detailed implementation mode

[0025] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0026] Refer to Figure 1 , a preferred embodiment of the present utility model provides a flexible clamping mechanism, including: a flexible base assembly 10 that plays a flexible supporting role, a chuck 30 for clamping a glass product 20 to be ground, and a driving member 40 for driving the chuck 30 to act. The chuck 30 and the driving member 40 are respectively installed on the flexible base assembly 10, and the chuck 30 is connected to the driving end of the driving member 40, so as to open under the action of the driving member 40 for the glass product 20 to be placed in, and close after the glass product 20 is positioned and placed, so as to relatively clamp the glass product 20 along the length direction of the glass product 20. The flexible base assembly 10 is also used to buffer when the glass product 20 is processed with unbalanced force, so that the glass product 20 deflects to conform to the force.

[0027] When the flexible clamping mechanism of the present utility model works, first, the driving member 40 is started to drive the chuck 30 to open, and an external loading robot or loading mechanism, etc. clamps the glass product 20 into the opened chuck 30. After the glass product 20 enters and stabilizes, the driving member 40 drives the chuck 30 to close again, so as to relatively clamp the glass product 20 along the length direction of the glass product 20. After the clamping is completed, the loading robot or loading mechanism releases the glass product 20 and withdraws from the chuck 30, thereby realizing the stable clamping of the glass product 20. During grinding processing, when the glass product 20 is subjected to unbalanced force, the flexible base assembly 10 buffers the unbalanced force, so that the glass product 20 deflects to conform to the force, thereby protecting the glass product 20 from chipping, corner breaking, cracking, breaking, etc. due to unbalanced force.

[0028] The flexible clamping mechanism of the present utility model has a simple structural setting and a simple clamping operation for the glass product 20, thereby reducing the cost of mechanism preparation, improving the clamping positioning accuracy and clamping efficiency, and being applicable to the positioning and clamping of small glass products. The flexible clamping mechanism of the present utility model, compared with manual processing, can be combined with an automatic feeding mechanism and an automatic processing device for automatic processing, improving the processing efficiency, reducing the labor consumption, and stably clamping the glass product 20, so that the processing quality of each edge is unified, further improving the processing quality. In addition, since the glass product 20 is made of a fragile material and has a high surface finish requirement, it is impossible to directly clamp and operate on the surface. The chuck 30 of the present utility model clamps the glass product 20 relatively along the length direction of the glass product 20, thereby avoiding these problems caused by intermediate clamping. On the other hand, due to the setting of the flexible base assembly 10 in the flexible clamping mechanism of the present utility model, when the glass product 20 is subjected to unbalanced forces, the flexible base assembly 10 can buffer the unbalanced forces, causing the glass product 20 to deflect to conform to the forces, thereby protecting the glass product 20 from chipping, corner breaking, cracking, breaking, etc. due to unbalanced forces and improving the product yield rate.

[0029] Optionally, as Figure 1 shown, the chuck 30 includes a fixed clamping block 31 and a movable clamping block 32 that are relatively spaced apart. The fixed clamping block 31 is vertically and fixedly supported on the flexible base assembly 10. The driving member 40 is disposed on the flexible base assembly 10, and the movable clamping block 32 is fixedly mounted on the driving end of the driving member 40. In this optional solution, the driving member 40 is a slide cylinder. During operation, when the slide cylinder contracts, the movable clamping block 32 retreats relative to the fixed clamping block 31, and the distance between the two increases. After the external feeding mechanism clamps the glass product 20 and enters between the two, the slide cylinder extends, driving the movable clamping block 32 to move towards the fixed clamping block 31, and the movable clamping block 32 cooperates with the fixed clamping block 31 to clamp the glass product 20 relatively along the axis, thereby completing the clamping operation of the glass product 20. The chuck 30 of this optional solution has a simple structural setting and a simple action process, and the clamping operation of the glass product 20 is simple, which can effectively reduce the cost of mechanism preparation and the clamping and positioning difficulty of the glass product 20. On the other hand, since the glass product 20 is made of a fragile material and has a high surface finish requirement, it is impossible to directly clamp and operate on the surface. The chuck 30 of the present utility model can clamp the glass product 20 relatively along the length direction of the glass product 20 through the relatively spaced fixed clamping block 31 and movable clamping block 32, thereby avoiding these problems caused by intermediate clamping.

[0030] Furthermore, as Figure 1As shown, the chuck 30 further includes two positioning clips 33 made of plastic material. The two positioning clips 33 are respectively fixed on the opposite inner side wall surfaces of the fixed chuck 31 and the movable chuck 32, and the upper ends of the positioning clips 33 extend to be flush with the top ends of the corresponding fixed chuck 31 or movable chuck 32, or slightly lower than the top ends of the fixed chuck 31 and the movable chuck 32, so as to plastically clamp both ends of the glass product 20. In this alternative solution, by adding the positioning clips 33 made of plastic material, the clamping force required for clamping the glass product 20 can be achieved to stably clamp it, and at the same time, the problem that the fragile glass product 20 is easily broken during rigid clamping can be effectively prevented; in addition, since the clamping ends for clamping are reserved at both ends of the glass product 20 when it is cut and formed, in order to avoid the influence of the existence of the clamping ends on the clamping of the glass product 20 in this solution, the upper ends of the positioning clips 33 are extended to be flush with the top ends of the corresponding fixed chuck 31 or movable chuck 32, or slightly lower than the top ends of the fixed chuck 31 and the movable chuck 32, so as to use the positioning clips 33 to clamp both ends of the glass product 20, rather than both ends of the clamping ends, thereby improving the clamping accuracy and clamping stability.

[0031] Optionally, as Figure 1 shown, the flexible clamping mechanism further includes two sets of in-place detectors 50 for detecting whether the glass product 20 is clamped in place. The two sets of in-place detectors 50 are respectively arranged on the opposite inner side wall surfaces of the fixed chuck 31 and the movable chuck 32, so as to detect whether there is a glass product 20 within the set detection distance, and then reflect whether the glass product 20 is clamped in place. Since the glass product 20 is fragile, if it is processed without being clamped in place, it is easy to break and chip. Therefore, during processing, it should be parallel to the processing tool, that is, the glass product 20 is horizontally arranged for processing. To detect whether the clamped glass product 20 is horizontal, a set of in-place detectors 50 with the same installation height are respectively arranged at both ends of the glass product 20, for detecting whether there is a glass product 20 within the set detection distance. When both sets of in-place detectors 50 detect the glass product 20, it indicates that the glass product 20 is clamped in place. When one set of in-place detectors 50 or both sets of in-place detectors 50 do not detect the glass product 20, it means that the glass product 20 is not clamped in place, and thus the controller alarms to remind to reposition and clamp.

[0032] In this alternative solution, as Figure 1 shown, the in-place detector 50 includes a fixed block 51 that is horizontally adjustable and connected to the inner side wall surface of the corresponding fixed chuck 31 or movable chuck 32, and a proximity sensor 52 that is vertically adjustable and installed on the fixed block 51. The proximity sensor 52 is located below the clamped glass product 20, so as to detect whether there is a glass product 20 within the set detection distance. Only when both proximity sensors 52 detect the glass product 20, it indicates that the glass product 20 is horizontally clamped and meets the clamping requirements.

[0033] In a specific embodiment of this alternative solution, as Figure 1 shown, on the inner side wall surfaces of the fixed clamping block 31 and the movable clamping block 32 facing each other, there are correspondingly provided mounting transverse grooves 301 that are concave and extend horizontally in the width direction. A plurality of first threaded holes are sequentially arranged at intervals along the transverse direction at the bottom of the mounting transverse groove 301. An installation vertical hole for the proximity sensor 52 to pass through vertically is formed in the fixed block 51, and a second threaded hole that is vertically communicated with the installation vertical hole and penetrates the outer wall surface of the fixed block 51. The side end of the fixed block 51 is slidably embedded in the mounting transverse groove 301 and is fixed in the mounting transverse groove 301 by a first fastener passing through it and the corresponding first threaded hole; during installation, by adjusting the position of the first fastener and the matching first threaded hole, the installation position of the fixed block 51 along the transverse direction is adjusted, so that the proximity sensor 52 corresponds to the detection of glass products 20 with different widths or different transverse clamping positions, improving the detection adaptation range. The mounting rod of the proximity sensor 52 passes through the installation vertical hole and is tightly fixed to the fixed block 51 by a second fastener passing through the second threaded hole; during installation, by adjusting the position of the mounting rod of the proximity sensor 52 in the installation vertical hole, the installation height of the proximity sensor 52 is adjusted, so that it corresponds to the detection of glass products 20 with different thicknesses and sizes, improving the detection adaptation range.

[0034] Optionally, as Figure 1 shown, each of the two positioning clips 33 is also provided with a ventilation hole that penetrates the positioning clip 33 and the corresponding fixed clamping block 31 or movable clamping block 32. The air inlet end of the ventilation hole is connected with a nozzle 60 for connecting with an external air supply device, so that the pressurized gas passes through the ventilation hole and blows away the debris staying on the positioning clip 33 and the in-place detector 50, improving the clamping stability and clamping accuracy of the positioning clip 33 for the glass product 20, as well as the detection accuracy of the in-place detector 50.

[0035] Optionally, as Figure 1 shown, the flexible base assembly 10 includes a support base 11, a plurality of elastic columns 12 vertically supported on the support base 11, and a support plate 13 supported on the upper ends of the plurality of elastic columns 12. The chuck 30 and the driving member 40 are respectively installed on the support plate 13. In this alternative solution, the structure of the flexible base assembly 10 is simply arranged and is easy to process and prepare. At the same time, while providing the flexible force required for the support plate 13 through the plurality of elastic columns 12, the structural arrangement of the flexible base assembly 10 is greatly simplified.

[0036] In this alternative solution, as Figure 2As shown, each elastic column 12 includes a mounting bolt 121 and a spring 122 for providing flexible support elasticity. The mounting bolt 121 is vertically arranged, with its bottom end fixed to the support base 11, and the opposite top end passing through the support plate 13 upward. The spring 122 is sleeved on the outer circumference of the mounting bolt 121 along the length direction of the mounting bolt 121, and the upper and lower ends of the spring 122 are respectively limited within the support plate 13 and the support base 11 to elastically support the support plate 13. When the glass product 20 is subjected to unbalanced forces, the four elastic columns 12 will buffer accordingly, causing the glass product 20 to deflect to conform to the force, that is, driving the glass product 20 to fit the force direction, thereby protecting the glass product 20 from being broken or chipped due to unbalanced forces.

[0037] Preferably, as Figure 2 shown, the support plate 13 is provided with a through hole for the mounting bolt 121 to pass through. An upper limit groove that is concave and used to limit the upper end of the spring 122 is further provided on the lower surface of the support plate 13, and the upper limit groove is coaxially communicated with the through hole. A lower limit groove that is concave and used to limit the lower end of the spring 122 is further provided on the upper surface of the support base 11. The upper and lower ends of the spring 122 respectively extend into the upper limit groove and the lower limit groove for limitation. The diameter of the through hole and the inner diameter of the spring 122 are both larger than the outer diameter of the screw rod of the mounting bolt 121. In this preferred solution, first, the flexible base assembly 10 is supported by four compression springs, enabling up and down floating and being flexible. Secondly, the structure of the spring 122 is as Figure 2 shown. Since the diameter of the through hole and the inner diameter of the spring 122 are both larger than the outer diameter of the screw rod of the mounting bolt 121, the overall structure can swing slightly in all directions, driving the glass product 20 to fit the force direction, and the spring 122 is simultaneously limited within the upper limit groove of the support plate 13 and the lower limit groove of the support base 11.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
