Description

Technical Field

[0001] The utility model relates to the technical field of material transfer equipment, in particular to an emergency unblocking device for a crystal rod conveying roller conveyor line. Background Art

[0002] At present, the square rods obtained from the square process of single-wafer silicon rods need to be transported to the next process through an automated roller line. The automated roller line contains several rollers connected by rubber chains or tank chains, and each roller is about 2.2 meters long. When one of the rollers has a bearing damage or chain breakage, it is necessary to stop the roller group of the current section and replace the bearing / chain in time. During the replacement process, in order to maintain production efficiency, the upstream and downstream roller groups will not stop operating, so employees are required to directly carry the crystal rods delivered by the upstream roller group to the downstream roller group by hand to prevent the crystal rod from being blocked. However, due to the narrow space, the bearing / chain replacement process takes 2 hours, which means that the manual lifting and transfer of the crystal rods also takes such a long time, which is very labor-intensive, and the crystal rods are easy to slip from the hands after the employees are tired, which poses a great safety hazard.

[0049] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0050] See also Figure 1 to Figure 4 As shown, the utility model provides an emergency unblocking device for a crystal rod conveying roller conveyor line, comprising:

[0051] The frame 100 is movably arranged above the roller table group to be repaired;

[0052] The first moving mechanism 200 is connected to the frame 100 and can reciprocate along the conveying direction of the crystal rod conveying roller line (not shown in the figure);

[0053] The second moving mechanism 300 is connected to the first moving mechanism 200 and can reciprocate in the vertical direction; and

[0054] The grabbing mechanism 400 is connected to the second moving mechanism 300 and is used to grab the crystal rod 600 to achieve the transfer of the crystal rod between the upstream and downstream roller sets.

[0055] When a roller section of the crystal rod conveying roller line has a bearing damage or a chain breakage, the device is placed at the roller group of the current section (i.e., the roller group to be repaired), and the roller group of the current section is stopped to replace the damaged bearing or broken chain; at this time, the first moving mechanism 200 is actuated, and moves the second moving mechanism 300 and the grasping mechanism 400 to the upstream of the roller group of the current section, and then the second moving mechanism 300 moves downward, so that the grasping mechanism 400 moves toward the crystal rod sent by the upstream roller group, and then the grasping mechanism 400 is actuated to grasp the current crystal rod, and then the second moving mechanism 300 moves upward, and at the same time the first moving mechanism 200 moves in the opposite direction, and moves the grasping mechanism 400 to the downstream of the roller group of the current section, and then the second moving mechanism 300 moves downward again, and finally the grasping mechanism 400 releases the crystal rod and transfers it to the downstream roller group, and then the operation is repeated to alleviate the upstream material blockage and achieve unblocking, thereby not affecting the replacement of bearings or chains. That is to say, the frame 100 is used to build a bridge over the faulty crystal rod conveying roller group, and through the cooperation of the first moving mechanism 200, the second moving mechanism 300 and the grasping mechanism 400, the crystal rods continuously delivered from the upstream are transferred to the downstream without affecting the maintenance of the faulty roller group, which solves the problem of material blockage on the roller line to a certain extent, maintains production efficiency, and improves the safety of the crystal rod transfer process.

[0056] The first moving mechanism 200 includes a first carrier plate 210, a first motor 220, a first ball screw 230 and a first slide 240. The first carrier plate 210 is horizontally connected to the upper end of the frame 100. The first motor 220 is fixedly installed at one end of the first carrier plate 210. One end of the first ball screw 230 is transmission-connected to the output end of the first motor 220, and the other end is rotationally connected to the other end of the first carrier plate 210. The first slide 240 is transmission-connected to the first ball screw 230 and slidably cooperates with the first carrier plate 210. When the first motor 220 is started, the first slide 240 is driven by the first ball screw 230 to slide along the length direction of the first carrier plate 210, thereby realizing horizontal reciprocating movement.

[0057] The second moving mechanism 300 includes a second carrier plate 310, a second motor 320, a second ball screw 330 and a second slide 340. The second carrier plate 310 is vertically connected to the first slide 240. The second motor 320 is fixedly installed on the upper end of the second carrier plate 310. One end of the second ball screw 330 is transmission-connected to the output end of the second motor 320 and the other end is rotationally connected to the lower end of the second carrier plate 310. The second slide 340 is transmission-connected to the second ball screw 330 and slidably cooperates with the second carrier plate 310. When the second motor 320 is started, the second slide 340 is driven by the second ball screw 330 to slide along the length direction of the second carrier plate 310, thereby realizing reciprocating movement in the vertical direction.

[0058] In order to improve the stability of the first slide 240 and the second slide 340 during sliding, a pair of first guide rods 211 are provided on the first carrier plate 210, and the first guide rods 211 are located parallel to both sides of the first ball screw 230 and slide through the first slide 240; a pair of second guide rods 311 are provided on the second carrier plate 310, and the second guide rods 311 are located parallel to both sides of the second ball screw 330 and slide through the second slide 340.

[0059] The grasping mechanism 400 includes a support 410 and a suction cup 420 connected to the bottom of the support 410 and used to absorb the crystal rod. The support 410 is fixedly connected to the second slide 340. The suction cup 420 is externally connected to a negative pressure generator (such as a vacuum pump, not shown in the figure) to provide suction for the suction cup 420 to absorb the crystal rod. That is, the grasping mechanism 400 absorbs the crystal rod through the suction force generated by the negative pressure generator at the suction cup 420.

[0060] The suction cup 420 is connected to the bottom of the support 410 through the third guide rod 430. The third guide rod 430 is provided with a spring 440. The two ends of the spring 440 are respectively in contact with the lower end surface of the support 410 and the back surface (non-working surface) of the suction cup 420. When the grasping mechanism 400 moves down to the suction cup 420 and contacts the crystal rod, the spring 440 can play a buffering role, reducing the rigid collision between the suction cup 420 and the crystal rod, thereby effectively avoiding damage to the crystal rod and ensuring the quality of the crystal rod.

[0061] In this embodiment, a pair of suction cups 420 are provided symmetrically to the second ball screw 330. The gripping mechanism 400 simultaneously absorbs a crystal rod through a pair of suction cups 420, which has a greater suction force and can prevent the crystal rod from falling off during the transfer process, further improving the safety of the crystal rod transfer process.

[0062] The above-mentioned emergency unblocking device for the crystal rod conveying roller conveyor further includes a control cabinet 500 placed on the ground and located on one side of the frame 100. The control cabinet 500 is electrically connected to the first motor 220, the second motor 320 and the negative pressure generator respectively. Through the control cabinet 500, the staff can control the coordinated action of the first moving mechanism 200, the second moving mechanism 300 and the grasping mechanism 400, so as to quickly realize the transfer of the crystal rod.

[0063] Casters (not shown) are provided at the lower end of the frame 100. After the maintenance work of the current roller group (replacing bearings or chains) is completed, the staff can push the device away through the casters to restore the original state of the crystal rod conveying roller line.

[0064] In this embodiment, the frame 100 is an aluminum profile frame. The aluminum profile frame is conducive to reducing the weight of the device, and it is more labor-saving when employees push it.

[0065] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
