Description

Technical Field

[0001] The utility model belongs to the technical field of wire cutting, and in particular relates to a cutting chamber and wire cutting equipment. Background Art

[0002] Photovoltaic and semiconductor silicon wafers are processed by wire cutting machines. During the cutting process, there will be wire merging and wire jumper conditions. At the same time, due to the downward pressure of the bar material, the entire wire mesh will produce wire bows. The above-mentioned wire merging, wire jumper and wire bow height changes will directly affect the quality of the slices. Therefore, a device is needed to detect the wire mesh status to adjust the cutting process. This is generally done by installing the distance sensor on the support arm, the support arm on the linear module, and the linear module on the upper part of the cutting chamber of the wire cutting machine.

[0003] Most existing wire mesh detection devices use support arms to fix detection sensors. Since there are many parts inside the cutting room of the equipment and the detection device is relatively large, installing the detection device in a limited space limits the daily disassembly, maintenance and cleaning of some parts. At the same time, high-pressure water flushing is required to clean the various parts in the cutting room after each cutting, and the detection device is easily damaged by water flushing.

[0004] Based on the above content, the technical problem to be solved by the present application is: how to avoid interference between the detection device and the cutting chamber operation. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and propose a cutting chamber and wire cutting equipment to solve the problem of interference between the detection device and the cutting chamber operation in the prior art. The technical effect of the application scheme is to avoid interference between the detection device and the cutting chamber operation.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a cutting room, comprising: a frame, a first area and a second area are arranged in the frame, the first area is used for the operation of a device or a workpiece, and the second area is arranged adjacent to the first area and is used to avoid the entry and exit of the device or workpiece in the first area; a cutting main roller, the cutting main roller is at least 2 and is arranged in the first area, and is used to arrange the cutting wire net; and a detection device, the detection device comprises: a detection component, the detection component is arranged on the outside of the cutting main roller, and is used to detect the cutting main roller and / or the cutting wire net; a movable component, the movable component is movably / detachably arranged on the frame and connected to the detection component, and drives the detection component to leave or enter the second area in a movable / disassembly manner.

[0007] Exemplarily, a spray device is generally configured in the first area, and the spray device needs to be frequently disassembled from the cutting room for cleaning. After disassembly, it generally passes through the adjacent second area from the first area and then leaves the cutting room. However, in order to ensure the accuracy of the detection, the detection device needs to align the cutting main roller and the cutting wire net X at a close distance in the second area for detection. Therefore, when the disassembled spray device passes through the second area, it will interfere with the detection device. In order to avoid mutual interference between the two, the present application uses a movable component in the detection device to drive the detection component to move away from the second area to avoid the spray device, or disassembles the detection device to move away from the second area to avoid the spray device. When the detection device needs to be used, it can be reset again by moving, or reassembled on the frame. Exemplarily, the detection component is a laser sensor or a CCD camera.

[0008] In the above-mentioned cutting chamber, the movable assembly includes: a movable base, the movable base is slidably connected to the frame; a movable arm, the movable arm is slidably / rotatably / telescopically connected to the movable base, and the movable arm is connected to the detection assembly. In some embodiments, the movable assembly includes a movable base and a movable arm, the movable base is slidably connected to the frame, the movable arm specifically includes a first movable arm and a second movable arm, a connecting block is provided between the first movable arm and the movable base, the movable base and the connecting block are hinged by a first movable joint, the connecting block and the first movable arm are hinged by a second movable joint, the first movable arm and the second movable arm are hinged by a third movable joint, and the second movable arm and the detection assembly are hinged by a fourth movable joint.

In some embodiments, the movable arm and the movable base are connected by sliding blocks and slide rails to achieve sliding connection. In some embodiments, the movable arm and the movable base are telescopically connected by providing a telescopic sleeve and a telescopic driving unit that drives the telescopic sleeve to extend and retract.

[0009] In the above-mentioned cutting chamber, the movable arms are multiple and are movably connected to each other. It can be understood that when there are multiple movable arms, the detection angle range of the detection component is increased, and the detection distance and range relative to the cutting main roller or the cutting wire net X can be greatly improved to get rid of the dirty liquid or high-concentration silicon powder environment in the cutting chamber, and meet the detection requirements of short and long distances at the same time. Due to the large detection range, more data is obtained from the detection, and the final judgment of the detection result is more accurate.

[0010] In the above-mentioned cutting chamber, the movable component and the detection component are connected in a rotational / sliding / telescopic manner. It is understandable that the connection mode between the movable component and the detection component can be selected differently based on the spatial form of the second area. For example, when the movable component and the detection component are connected in a rotational manner, there is a hinge shaft and a hinge hole between the movable component and the detection component, and the hinge shaft is inserted into the hinge hole to achieve a rotational connection between the two. When the movable component and the detection component are connected in a sliding manner, a slide rail and a slider are provided between the movable component and the detection component to achieve a sliding connection between the two.

[0011] In the above-mentioned cutting chamber, a storage slot is provided on the frame and outside the second area, so that the movable component can drive the detection component to move into / remove and store it. It can be understood that by providing the storage slot on the frame, the movable component can drive the detection component to move into the storage slot to leave the second area, or the disassembled movable component and / or detection component can be stored in the storage slot.

[0012] In the above-mentioned cutting room, a placement table is provided on the frame and outside the second area, so that the movable component can drive the detection component to move against / disassemble and place. It can be understood that by providing the placement table on the frame, the movable component can drive the detection component to move against the placement table to leave the second area, or the disassembled movable component and / or detection component can be placed on the placement table.

[0013] In the above-mentioned cutting room, the frame is provided with an auxiliary positioning member, and the detection component moves to detect the auxiliary positioning member for positioning. It can be understood that the auxiliary positioning member is configured at a specific position on the frame, and the initial position of the detection component is configured as a specific position corresponding to the auxiliary positioning member. Based on the detection information of the detection component, the movable component is controlled to continuously move and adjust the position of the detection component until the positioning is completed, so as to ensure that the detection data can be effectively obtained without missing detection.

[0014] In the above-mentioned cutting chamber, a matching structure is provided between the frame and the movable component, and the matching structure includes: a first matching portion, the first matching portion is arranged on the frame; a second matching portion, the second matching portion is arranged on the movable component; wherein the second matching portion is detachably connected to the first matching portion. It can be understood that for the movable component of the disassembly and assembly method, the positioning can be completed by matching with the shape of the frame. Exemplarily, the first matching portion is concave in shape, and the second matching portion is convex in shape, and the two are interlocked to facilitate reassembly and positioning. Alternatively, the outer circle of the first matching portion and the outer circle of the second matching portion are in the form of mutual coupling, and the two are disassembled and reassembled in the axial direction.

[0015] In the above-mentioned cutting chamber, a guide mechanism is provided on the frame, and the guide mechanism acts on the movable component to make the movable component move in an axial direction parallel to the cutting main roller. It can be understood that by providing the guide mechanism, the linear motion accuracy of the movable component can be guaranteed, thereby ensuring the accuracy of the linear scanning detection of the detection component. Exemplarily, the guide mechanism includes a first guide member and a second guide member, the first guide member is a guide rail, which is provided on the frame, and the second guide member is a guide groove, which is provided on the movable component, and the guide rail and the guide groove match each other.

The movable component 320 is movably / detachably arranged on the frame 100 and connected to the detection component 310, and drives the detection component 310 to leave or enter the second area 120 in a movable / disassembly manner. Exemplarily, a spray device 600 is generally configured in the first area 110, and the spray device 600 needs to be frequently disassembled from the cutting chamber for cleaning. After disassembly, it generally passes through the adjacent second area 120 from the first area 110 and then leaves the cutting chamber.

It can be understood that when there are multiple movable arms 322, the detection angle range of the detection component 310 is increased, and the detection distance and range relative to the cutting main roller 200 or the cutting wire mesh X can be greatly improved to get rid of the dirty liquid or high-concentration silicon powder environment in the cutting room, while meeting the detection needs of short and long distances.
