Description

Technical Field

[0001] The present invention belongs to the technical field of flat glass manufacturing by the overflow down-draw method, and particularly relates to an edge auxiliary transmission and positioning mechanism for substrate glass. Background Art

[0002] The overflow down-draw method is one of the main methods for flat glass production. Mainly, the molten glass liquid overflows on both sides of the refractory chute and converges at the pointed part at the lower end of the chute to form a glass plate, which is formed into a glass plate after being pulled by a traction mechanism.

[0003] The prior art has the following problems: During normal production, the glass plate flows down to a cross-cutting machine for cutting and breaking, and is transported to a conveyor tooling cart by a robot. The tooling cart runs on the conveyor to different processing stations for processing the product specifications. During the transmission of the substrate glass, if the edge of the substrate glass comes into contact with both sides of the conveyor, it will cause the transmission position of the substrate glass to shift. At the same time, this contact will cause the transmission speed of the substrate glass to decrease. Therefore, there is an urgent need for an edge auxiliary transmission and positioning mechanism for substrate glass to solve the above problems. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides an edge auxiliary transmission and positioning mechanism for substrate glass, which has the characteristics of facilitating the transmission of substrate glass.

[0005] To achieve the above object, the present invention provides the following technical solution: An edge auxiliary transmission and positioning mechanism for substrate glass, including a telescopic adjustment base frame assembly. A plurality of edge auxiliary transmission wheel assemblies for substrate glass are arranged on the telescopic adjustment base frame assembly. A belt tightening assembly is arranged on the telescopic adjustment base frame assembly and the edge auxiliary transmission wheel assemblies for substrate glass. The belt tightening assembly forms a self-counteracting and tightening structure for the belt. A transmission positioning and acceleration structure for the edge of the substrate glass is formed between two edge auxiliary transmission wheel assemblies for substrate glass;

[0006] The telescopic adjustment base frame assembly includes a U-shaped base frame. A bidirectional threaded screw, an end mounting table, and a driving motor are arranged on the U-shaped base frame. Internal threaded seat blocks are threadedly arranged at both ends of the bidirectional threaded screw. Telescopic arms are arranged on two internal threaded seat blocks. A plurality of central axis points are arranged on the telescopic arms. A plurality of fixed bottom shaft platforms are rotatably arranged at intervals on the plurality of central axis points. A top plate is arranged on the top of the fixed bottom shaft platform. A rotating shaft rod is rotatably arranged on the top plate. A small-diameter belt pulley and a large-diameter belt pulley are arranged on the rotating shaft rod.

[0007] Preferably, the auxiliary transmission wheel assembly at the edge of the substrate glass includes a transmission wheel support frame and a fixed base shaft platform. An axial platform support rod and a guiding convex arm plate are arranged on the fixed base shaft platform. A guiding transverse groove is arranged on the guiding convex arm plate. A transverse beam rod is arranged at the top of the axial platform support rod. A middle tightening disc and an end tightening disc are respectively arranged in the middle and at the ends of the transverse beam rod. First tightening springs and second tightening springs are sleeved at both ends of the transverse beam rod. End perforated frame platforms and driving shaft rods are respectively arranged at both ends of the transmission wheel support frame. A first driving pulley, a second driving pulley and an outer rubber-coated roller are arranged on the driving shaft rod. A side support frame plate is arranged on one side of the top of the transmission wheel support frame. A transmission belt is arranged on the second driving pulley;

[0008] The belt tightening assembly includes a tightening slide rod. A slide rod end platform and a belt tightening wheel are arranged on the tightening slide rod. A tightening spring is sleeved on the tightening slide rod.

[0009] Preferably, the fixed base shaft platform is rotationally connected to the arm body at the central axis point through a shaft pin. The rod body at the bottom of the top frame plate reciprocally slides in the guiding transverse groove. The transmission belt is wound between the second driving pulley and the small-diameter pulley. The other transmission belt is wound between the large-diameter pulley and the first driving pulley.

[0010] Preferably, the outer rubber-coated rollers on multiple groups of the auxiliary transmission wheel assemblies at the edge of the substrate glass form a blocking and positioning structure during the transmission of the edge of the substrate glass. The glass substrate during transmission drives the outer rubber-coated roller that is first contacted to rotate.

[0011] Preferably, the second driving pulley forms an acceleration structure for the small-diameter pulley through the transmission belt. The small-diameter pulley and the large-diameter pulley rotate at the same speed. A synchronous rotation structure is formed between the large-diameter pulley and the first driving pulley through the transmission belt.

[0012] Preferably, the tightening slide rod penetrates and slides through the side support frame plate or the top frame plate. The tightening spring respectively abuts against the belt tightening wheel and the side support frame plate or the top frame plate. Through the tightening of the tightening spring, the belt tightening wheel is in a pushing and tightening structure for the transmission belt.

[0013] Preferably, the end perforated frame platform reciprocally slides on the transverse beam rod. Through the first tightening spring and the second tightening spring, the end perforated frame platform forms an elastic buffer reciprocating sliding structure on the transverse beam rod.

[0014] Preferably, the telescopic adjustable base frame assembly is fixed to one side of the glass substrate transfer rack through fastening bolts and an end mounting table. A pre-contact transfer positioning mechanism is formed between the glass substrate and the substrate glass edge auxiliary transfer wheel assembly that first comes into contact with it, and an acceleration transfer positioning mechanism is formed between the glass substrate and the substrate glass edge auxiliary transfer wheel assembly that comes into contact later.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention is in use, the telescopic adjustable base frame assembly is fixed to one side of the glass substrate transfer rack through fastening bolts and an end mounting table. At this time, the outer rubber rollers on multiple substrate glass edge auxiliary transfer wheel assemblies form a blocking and positioning structure during the transfer of the substrate glass edge. The glass substrate being transferred will drive the outer rubber roller that first comes into contact to rotate. When multiple substrate glass edge auxiliary transfer wheel assemblies are used in combination, the second driving pulley forms an acceleration structure for the small-diameter pulley through a transmission belt. The small-diameter pulley and the large-diameter pulley rotate at the same speed, and a synchronous rotation structure is formed between the large-diameter pulley and the first driving pulley through a transmission belt. In this way, a pre-contact transfer positioning mechanism is formed between the glass substrate and the substrate glass edge auxiliary transfer wheel assembly that first comes into contact with it, and an acceleration transfer positioning mechanism is formed between the glass substrate and the substrate glass edge auxiliary transfer wheel assembly that comes into contact later. In this way, positioning, limiting, and acceleration during the transfer of the substrate glass edge are achieved. During actual use, the driving motor drives the bidirectional threaded screw to rotate bidirectionally. At this time, the two internally threaded seat blocks move synchronously closer or farther away. At this time, the telescopic arm is in an extended motion. At this time, the spacing between multiple substrate glass edge auxiliary transfer wheel assemblies is adjustable. The top-tightening slide rod penetrates and slides through the side support plate or the top plate. The top-tightening springs respectively abut against the belt tensioning pulley and the side support plate or the top plate. Through the tightening of the top-tightening springs, the belt tensioning pulley forms a top-pushing and tightening structure for the transmission belt. In this way, when the spacing between multiple substrate glass edge auxiliary transfer wheel assemblies is adjusted, the transmission belt is always in a tightened mechanism, ensuring the transmission function of the transmission belt for the belt pulley. The end perforated platform slides reciprocally on the transverse beam rod. Through the first top-tightening spring and the second top-tightening spring, the end perforated platform forms an elastic buffer reciprocating sliding structure on the transverse beam rod. In this way, a flexible contact between the substrate glass edge and the outer rubber roller is achieved, ensuring safety when contacting the substrate glass edge. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the rubber-coated rollers 203 on multiple sets of substrate glass edge auxiliary transmission wheel assemblies 200 form a blocking and positioning structure during the transmission of the substrate glass edge. The glass substrate in transmission will drive the rubber-coated roller 203 that is first contacted to rotate. When multiple sets of substrate glass edge auxiliary transmission wheel assemblies 200 are used in cooperation, the second driving pulley 205 forms an acceleration structure for the small-diameter pulley 110 through the transmission belt 207. The small-diameter pulley 110 and the large-diameter pulley 112 rotate at the same speed. A synchronous rotation structure is formed between the large-diameter pulley 112 and the first driving pulley 202 through the transmission belt 207. In this way, a pre-contact transmission positioning mechanism is formed between the glass substrate and the substrate glass edge auxiliary transmission wheel assembly 200 that is first contacted, and an acceleration transmission positioning mechanism is formed between the glass substrate and the substrate glass edge auxiliary transmission wheel assembly 200 that is contacted later. In this way, the positioning, limiting, and acceleration during the transmission of the substrate glass edge are realized.

At this time, the two internally threaded seat blocks 106 are in the action of approaching or separating synchronously. At this time, the telescopic arm 102 is in the extending action. At this time, the spacing of multiple sets of substrate glass edge auxiliary transmission wheel assemblies 200 is adjustable.

The top tightening springs 303 respectively abut against the belt top tightening wheel 302 and the side support plate 204 or the top plate 109. Through the top tightening of the top tightening springs 303, the belt top tightening wheel 302 forms a top pushing and tightening structure for the transmission belt 207.
