Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a glass thickness self-adapting clamping and feeding device. Background Art

[0002] In the automatic gluing of insulating glass, the glass needs to be transported vertically. The existing gluing machine uses support blocks installed on the chains on both sides. The glass enters the chain and is dragged by the support blocks for transportation. The width in the middle of the chains on both sides is automatically adjusted according to the thickness of the glass, and then the width in the middle of the chain is locked by the locking cylinder. Since the locking force is difficult to adjust, when the glass is thick or heavy, it is difficult to lock the width of the chains on both sides, which easily causes the glass to fall off during the transmission process. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a glass thickness adaptive clamping device, which automatically adjusts the clamping gap width and the corresponding clamping force according to the thickness of the clamped glass, thereby ensuring stable clamping of glasses of different thicknesses during the entire clamping process and avoiding the falling of glass.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a glass thickness adaptive clamping device, comprising a clamping mechanism clamped on both sides of the glass, wherein the two clamping mechanisms are respectively connected to the output ends of the corresponding spacing adjustment mechanisms; a locking mechanism is provided on the side of the clamping mechanism away from the glass, and the locking mechanism is provided with a locking force adjustment module; a ranging module is provided between the two clamping mechanisms, and the signal output end of the ranging module is electrically connected to the locking force adjustment module through a control module.

[0005] Furthermore, the pinching mechanism comprises a plurality of pinching units, and the pinching units of the two pinching mechanisms are symmetrically arranged relative to the two sides of the pinched glass; the pinching units are provided with pinching rollers attached to the side end faces of the glass and supporting blocks attached to the bottom end faces of the glass.

[0006] Furthermore, the locking mechanism includes a pressure plate connected to the pinching unit and a cylinder group facing the pressure plate, and multiple output ends of the cylinder group press against the end surface of the pressure plate facing away from the glass.

[0007] Furthermore, the multiple cylinders of the cylinder group are connected to the air supply device through multiple air paths, each of the air paths is provided with a ventilation valve, and the distance measuring module is electrically connected to the multiple ventilation valves through the control module.

[0008] Furthermore, the multiple cylinders of the cylinder group are symmetrically arranged in pairs relative to the corresponding pinching units, and the two symmetrical cylinders are connected to the same air circuit.

[0009] Furthermore, the cylinders at corresponding positions on both sides of the glass are connected to the same gas circuit.

[0010] Beneficial effect: The utility model provides a glass thickness adaptive clamping and conveying device, which adopts two clamping and conveying mechanisms with adjustable relative spacing to clamp the glass for transmission, so that the device can adaptively clamp and convey glass of various thicknesses. By setting a locking mechanism with adaptively adjustable locking force, the clamping force applied to the glass by the clamping mechanisms on both sides can be adaptively adjusted according to the thickness of the glass, thereby ensuring stability during the clamping and conveying process, maintaining a stable spacing between the clamping mechanisms on both sides, and avoiding the falling of the glass. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 This is a schematic diagram of the overall structure of an embodiment of the utility model;

[0012] Attached Figure 2 The figure is a partial structural diagram of a locking mechanism according to an embodiment of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2 The glass thickness adaptive clamping device comprises a clamping mechanism 1 clamped on both sides of the glass, and the two clamping mechanisms 1 are respectively connected to the output ends of the corresponding spacing adjustment mechanisms 2; a locking mechanism 3 is provided on the side of the clamping mechanism 1 away from the glass, and the locking mechanism 3 is provided with a locking force adjustment module; a distance measuring module 4 is provided between the two clamping mechanisms 1, and the signal output end of the distance measuring module 4 is electrically connected to the locking force adjustment module through a control module.

[0015] This solution uses two clamping mechanisms to vertically clamp the glass and clamp it forward, thereby realizing the glass transmission function. The clamping mechanisms on both sides are respectively installed on the spacing adjustment mechanism, so that the spacing between the two clamping mechanisms can be adjusted. Therefore, when clamping glasses of different thicknesses, the spacing can be adaptively adjusted according to the thickness of the glass. A locking mechanism is provided to provide sufficient locking force to lock the spacing between the two clamping mechanisms to avoid glass falling off due to the increase in the spacing during the clamping process. A distance measuring module is provided to monitor the spacing between the clamping mechanisms on both sides of the glass, and the locking force of the locking mechanism is adjusted accordingly according to the change in the spacing. When the spacing increases, the locking force is appropriately increased to ensure that the clamping process is more stable when clamping larger and thicker glasses.

[0016] The pinching mechanism 1 includes a plurality of pinching units, and the two pinching units of the pinching mechanism 1 are symmetrically arranged relative to the two sides of the pinched glass; the pinching unit is provided with a pinching roller 11 attached to the side end surface of the glass and a support block 12 attached to the bottom end surface of the glass. The two symmetrical pinching rollers are clamped on both sides of the vertical surface of the glass, and the relative rotation directions are opposite, and the two symmetrical support blocks hold the two side edges of the bottom surface of the glass, so that under the static friction drive of the two pinching rollers, the middle glass slides unidirectionally relative to the upper surface of the support block, so as to achieve the purpose of pinching the glass.

[0017] The locking mechanism 3 includes a pressure plate 31 connected to the pinching unit and a cylinder group facing the pressure plate 31. The multiple output ends of the cylinder group press against the end surface of the pressure plate 31 away from the glass. That is, the cylinder group applies an additional thrust to the corresponding pinching unit, so that the pressure of the pinching roller on the glass surface is greater. The cylinder groups on both sides act at the same time, thereby forming a greater clamping and locking force to maintain the stability of the distance between the pinching mechanisms on both sides, thereby avoiding the risk of glass falling off.

[0018] Preferably, the pressure plate can be connected to the output end of the spacing adjustment mechanism 2, and a plurality of pinching rollers are arranged on the pressure plate at equal intervals and are all rotatably arranged relative to the pressure plate. A support block is fixedly connected to the pressure plate below each pinching roller, and the pinching rollers and support blocks at corresponding positions constitute a pinching unit.

[0019] The multiple cylinders 32 of the cylinder group are connected to the air supply device 34 through multiple air paths 33. Each of the air paths 33 is provided with a vent valve 35. The distance measuring module 4 is electrically connected to the multiple vent valves 35 through the control module. The air supply device 34 and the cylinder group are connected through multiple air paths 33 to form a control air network. A single air path is provided with a single vent valve for controlling the on and off of the air path. The multiple cylinders connected to the same air path act synchronously. The distance signal fed back by the distance measuring module is used to control the number of on and off air paths, thereby controlling the number of corresponding acting cylinders to achieve the adjustment of the locking force. Before adjusting the locking force each time, all air paths are connected, and all cylinders are reset by extracting gas. Then, according to the feedback of the distance measuring signal, the number of connected air paths is adjusted, and then air is supplied, so that the corresponding number of cylinders act synchronously to provide just the right locking force to maintain the stability of the transmission of the sandwiched glass.

[0020] The multiple cylinders 32 of the cylinder group are symmetrically arranged in pairs relative to the corresponding pinching unit, and the two symmetrical cylinders 32 are connected to the same air path 33. That is, the two symmetrical cylinders about the pinching unit act synchronously, either applying pressure to the pressure plate at the same time, or separating from the pressure plate at the same time, thereby ensuring the force balance around the pinching unit.

[0021] The cylinders 32 at the corresponding positions on both sides of the glass are connected to the same air circuit 33. That is, when the locking force is increased or decreased, the two sides can be adjusted synchronously, so that the clamping force on the corresponding points on both sides of the glass is balanced, further ensuring the stability of the clamping and feeding, and avoiding the phenomenon of excessive pressure on one side causing the glass to deviate to one side, or causing overpressure to damage the glass.

[0022] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
