[0002] Currently, in the production process of silicon wafers, they need to be placed in a basket, and then the basket is immersed in a trough machine filled with alkaline solution through a robotic arm, and a basket detection rod and a sleeve are set at the bottom of the trough machine, and a sensor is set in the sleeve, so that the basket moves downward to squeeze the basket detection rod into the sleeve, so that the sensor senses the basket detection rod, thereby realizing self-detection of the basket.

[0003] However, when the robot arm performs the normal basket lifting and placing action, since the basket lifting detection rod has been in an alkaline solution environment for a long time, alkaline liquid crystals adhere to the basket lifting detection rod, increasing the friction between the basket lifting detection rod and the sleeve, causing blockage and jamming in the downward movement of the basket lifting detection rod, delaying the sensor signal induction, transmitting error information, and causing the machine to alarm and stop running, affecting the next action of the robot arm, causing the trough silicon wafer to time out, and the weight loss abnormality requires isolation and rework, which seriously affects the workshop yield indicators.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-2 A slot machine basket detection structure includes a mechanical arm 1 and a slot machine 2, wherein the slot machine 2 is provided with an alkaline solution.

[0021] A plurality of baskets 3 are provided, and a hanging rod 4 is fixedly connected to the upper end of the baskets 3.

[0022] At the end of the robotic arm 1, a plurality of connecting plates 5 corresponding to the plurality of baskets 3 are fixedly connected, and a hook 6 is fixedly connected to the side wall of the connecting plate 5. The hanging rod 4 is sleeved on the hook 6. The basket 3 can be moved up, down, left, right, forward and backward by the robotic arm 1, which is the prior art.

[0023] The detection mechanism includes a fixed cylinder 7 fixedly connected to the upper end of the hook 6, a detection rod 8 is slidably connected to the inner wall of the fixed cylinder 7, a base 9 is fixedly connected to the lower end of the detection rod 8, the upper end of the detection rod 8 is elastically connected to the top of the fixed cylinder 7 through a spring 10, a sensor 11 is embedded in the inner wall of the fixed cylinder 7, and a detection block 12 facing the sensor 11 is embedded in the side wall of the detection rod 8.

[0024] Furthermore, the detection mechanism is arranged on the hook 6 so that the detection rod 8 will not be immersed in the alkaline solution, thereby avoiding the prior art that the basket detection rod is in an alkaline solution environment for a long time, the alkaline liquid crystal is attached to the basket detection rod, the friction between the basket detection rod and the sleeve is increased, and the downward movement of the basket detection rod is blocked and stuck, causing the sensor signal induction delay, transmitting error information, the machine alarm stops running, affecting the next action of the robot arm, causing the trough body silicon wafer to time out, and the abnormal weight loss needs to be isolated and reworked, which seriously affects the workshop yield index;

[0025] At the same time, when there is no hanging rod 4 on the hook 6, the detection rod 8 moves downward under the elastic force of the spring 10, so that the detection block 12 is separated from the sensor 11, and there is no sensing signal on the sensor 11. When the hanging rod 4 is mounted on the hook 6, the lower end of the base 9 is fitted with the upper end of the hanging rod 4, pushing the detection rod 8 upward. At this time, the detection block 12 is facing the sensor 11, and there is a sensing signal on the sensor 11, and then subsequent operations are performed.

[0026] The sensor 11 transmits the detection result signal to the external PLC, and then transmits the converted signal to the external human-machine interface through the network cable. At this time, the external human-machine interface displays the alarm information and the buzzer alarm emits an audible and visual alarm to give the current state of the robot 1, complete the detection effect output, and realize the automatic processing of the work flow. This processing flow is a prior art and will not be repeated here.

[0027] The lower end of the fixing tube 7 is fixedly connected with an elastic ring 13, and the lower end of the elastic ring 13 is fixedly connected to the upper end of the base 9, which can protect the side wall of the detection rod 8 and prevent the alkaline liquid crystal from adhering to the side wall of the detection rod 8, thereby affecting its normal up and down sliding.

[0028] When soaking the silicon wafers, first, the hanging rod 4 on the basket 3 containing the silicon wafers is sleeved on the hook 6. At this time, the lower end of the base 9 is fitted with the upper end of the hanging rod 4, and the detection rod 8 is pushed upward. At this time, the detection block 12 is directly opposite to the sensor 11, and there is an induction signal on the sensor 11. Then the sensor 11 transmits the detection result signal to the external PLC and converts the signal to the external human-machine interface through the network cable. At this time, the external human-machine interface displays the alarm information and the buzzer alarm emits an audible and visual alarm to give the state of the robot arm 1 at this time, complete the detection effect output, and realize the automatic processing of the work process;

[0029] In addition, the detection mechanism is arranged on the hook 6, so that the detection rod 8 will not be immersed in the alkaline solution, thereby avoiding the problem in the prior art that the basket detection rod is in an alkaline solution environment for a long time, the alkaline liquid crystal is attached to the basket detection rod, the friction between the basket detection rod and the sleeve is increased, and the downward movement of the basket detection rod is blocked and stuck, which causes the sensor signal induction delay and transmits error information. The machine alarm stops running, affecting the next action of the robot arm, causing the trough silicon wafer to time out, and the weight loss abnormality needs to be isolated and reworked, which seriously affects the workshop yield index.

[0030] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
