Abstract
The utility model provides a silicon ingot incision wire saw with a wire break protection device, comprising two guide pulleys, an incision line surrounding at exterior of the two guide pulleys, and guide pulley guard boards arranged at interior of the two guide pulleys. When the incision wire incises the silicon ingot, the incision line will generate a line arch. A contact alarm arrester is arranged below the incision line for preventing the line arch from exceeding a maximum allowable value. After the incision line is contacts with the contact alarm arrester, the silicon ingot incision wire saw automatically alarms and shuts down. The silicon ingot incision wire saw of the utility model provides a silicon ingot incision device, which can discover abnormity of the line arch in time and avoid wire break.
Description
Technical field
The utility model relates to a kind of cutter sweep, relates in particular to a kind of silicon ingot cutter sweep.
Background technology
At present, during polysilicon, the hard spot broken string often takes place scroll saw in cutting, and it is very big often to cause broken string to cut damage, and often simultaneously guide wheel is damaged, and brings very big economic loss.The hard spot broken string is because excessive the causing of line bow if can find in time that the line bow is unusual, just can be avoided broken string.
The utility model content
The technical problems to be solved in the utility model is: a kind of silicon ingot cutter sweep is provided, makes it can find in time that the line bow is unusual, avoid broken string.
In order to overcome the defective that exists in the background technology; the technical scheme that its technical problem that solves the utility model adopts is: a kind of silicon ingot cutting fret saw with broken wire protecting equipment; comprise two guide wheels, be surrounded on the line of cut in two guide wheels outside and place the guide wheel backplate of two guide wheel inboards; when line of cut cutting silicon ingot; line of cut can produce the line bow; below described line of cut, be provided with the contact warning arresting gear that anti-principal vertical line bow surpasses its maximum permissible value, this silicon ingot cutting fret saw shutdown of reporting to the police automatically after line of cut touches contact warning arresting gear.
Described contact warning arresting gear comprises grounded metal spare and grounding alarm arresting gear, grounded metal spare ground connection, and the grounding alarm arresting gear is connected with line of cut.
Described grounded metal spare places on the guide wheel backplate.
The utility model has solved the defective that exists in the background technology, can find in time that the line bow is unusual, avoids broken string, and economic loss is reduced to minimum.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a silicon ingot cutter sweep structural representation in working order;
Fig. 2 is the perspective view of guide wheel backplate.
Wherein: 1, guide wheel, 2, line of cut, 3, the guide wheel backplate, 4, silicon ingot, 5, contact warning arresting gear, 51, grounded metal spare, 52, the grounding alarm arresting gear.
The specific embodiment
As shown in Figure 1; a kind of application rights requires the silicon ingot cutting fret saw of 1 described thread-breakage protecting; comprise two guide wheels 1, be surrounded on the line of cut 2 in two guide wheel 1 outsides and place the guide wheel backplate 3 of two guide wheel 1 inboards; when line of cut 2 cutting silicon ingots 4; line of cut 2 can produce line bow d; below line of cut 2, be provided with the contact warning arresting gear 5 that anti-principal vertical line bow d surpasses its maximum permissible value, this silicon ingot cutting fret saw shutdown of reporting to the police automatically after line of cut 2 touches contact warning arresting gear 5.Contact warning arresting gear 5 comprises grounded metal spare 51 and grounding alarm arresting gear 52, grounded metal spare 51 ground connection, and grounding alarm arresting gear 52 is connected with line of cut 2.Grounded metal spare 51 places on the guide wheel backplate 3.
The maximum permissible value of supposing line bow d is 12mm, and as shown in Figure 2, placing the grounded metal spare 51 on the guide wheel backplate 3 is a long metal bar, and when line of cut 2 during at cutting silicon ingot 4, hard spot causes that line bow d is excessive, when line bow d will break during greater than 12mm.In order effectively to protect line of cut 2, the grounded metal spare 51 on the guide wheel backplate 3 is set to 6mm with the vertical range D under line of cut 2 levels, and this vertical range D is relevant with the position of guide wheel backplate 3, can obtain by calculating or field trial.When the vertical range D under grounded metal spare on the guide wheel backplate 3 51 and line of cut 2 levels is set to 6mm; can guarantee when line bow d is 12mm above maximum permissible value; line of cut 2 contacts with grounded metal spare 51 on the guide wheel backplate 3; grounding alarm arresting gear 52 detects the just warning shutdown immediately of line of cut 2 ground connection, prevents the line of cut fracture.
