[0038] Embodiment 1

[0039] Combination Figures 1 to 3As shown, the material box detection device provided in this embodiment can timely and accurately grasp the accommodation status of the material box 10 on the main platform 100, thereby improving the loading efficiency. When applied to a centralized loading unit, the structure and principle of the material box detection device arranged on multiple workstations are exactly the same. In this embodiment, one group of material box detection devices is taken as an example to describe its specific structure and working principle. Specifically, the material box detection device includes a main platform 100 and a detection mechanism 200: the main platform 100 is used to carry the material box 10, and a detection channel 110 is arranged on the main platform 100; the detection mechanism 200 includes a trigger 210 and a pressing assembly 220, and the pressing assembly 220 includes a pressing member 221 and a reset member 222. The pressing member 221 is movably arranged on the lower end surface of the main platform 100 along the height direction corresponding to the detection channel 110, and at least a part of the pressing member 221 passes through the detection channel 110 and is exposed on the upper end surface of the main platform 100. The reset member 222 is arranged between the lower pressing member 221 and the main platform 100, the trigger member 210 is arranged opposite to the lower pressing member 221, and is communicated with the external display member, the lower pressing member 221 has a placement state and an idle state, when the lower pressing member 221 is in the placement state, the lower pressing member 221 moves in a direction away from the main platform 100, and can trigger the trigger member 210, so that the trigger member 210 sends a placement signal to the external display member; wherein, the material box 10 is placed on the main platform 100, so that the lower pressing member 221 is converted from the idle state to the placement state.

[0040] Since the pressing member 221 is movably arranged on the lower end surface of the main platform 100 along the height direction corresponding to the detection channel 110, at least a portion of the pressing member 221 passes through the detection channel 110 and is exposed on the upper end surface of the main platform 100, and the reset member 222 is arranged between the pressing member 221 and the main platform 100, when the pressing member 221 is in the placement state, the pressing member 221 can trigger the touch member 210, so that the touch member 210 sends a placement signal to the external display member. Therefore, during the silicon wafer processing, after the material box 10 containing silicon wafers is placed on the main platform 100, under the action of the gravity of the material box 10, the pressing piece 221 exposed on the upper end surface of the main platform 100 is pressed down into the detection channel 110, that is, the pressing piece 221 as a whole moves in the direction away from the main platform 100 under the gravity of the material box 10. At this time, the reset piece 222 undergoes elastic deformation, and the pressing piece 221 triggers the trigger piece 210, and the trigger piece 210 sends a placement signal to the external display component, so that the operator can promptly grasp that there is a material box 10 placed on the main platform 100 at this time. After the material box 10 is removed from the main platform 100, the lower pressing member 221 and the reset member 222 no longer bear the gravity of the material box 10, and the reset member 222 returns to its original state, and drives the lower pressing member 221 to move in the direction close to the main platform 100, so that part of the lower pressing member 221 passes through the detection channel 110 again and is exposed on the upper end surface of the main platform 100, so that after a new material box 10 is placed on the main platform 100, the trigger member 210 is triggered in time and accurately; at the same time, in this state, the trigger member 210 no longer sends a placement signal to the external display component, and the operator places the material box 10 containing silicon wafers on the main platform 100 in time according to the display status of the external display component. During the whole process, when the lower pressing member 221 bears the gravity of the material box 10, the trigger member 210 can be triggered in time and accurately to send a placement signal to the external display component, so that the operator can accurately grasp the presence or absence of the material box 10 on the main platform 100, thereby improving the loading efficiency.

[0041] Preferably, the trigger member 210 is configured as a micro switch and is fixedly arranged on the lower end surface of the main platform 100 through a connecting member 211. A trigger button 212 is arranged on the micro switch. The pressing member 221 includes a pressing portion 2211 and a trigger portion 2212 fixedly connected to the pressing portion 2211. The pressing portion 2211 is movably arranged on the lower end surface of the main platform 100 along the height direction corresponding to the detection channel 110. When the pressing portion 2211 is in a placement state, the trigger portion 2212 can trigger the trigger button 212.

[0042] The micro switch can be set to press the trigger button 212 to trigger the micro switch to send a placement signal to the external display. Under this setting, the trigger button 212 is set on the upper end surface of the micro switch. When the material box 10 is placed on the main platform 100, the pressing part 2211 bears the gravity of the material box 10 and moves in the direction away from the main platform 100 to drive the trigger part 2212 to move in the direction close to the trigger button 212, and press the trigger button 212 to make the trigger button 212 send a placement signal to the external display; after the material box 10 is removed from the main platform 100, the pressing part 2211 and the reset part 222 no longer bear the gravity of the material box 10, the reset part 222 returns to its original state, and drives the pressing part 2211 and the trigger part 2212 to move in the direction close to the main platform 100, and the trigger part 2212 no longer presses the trigger button 212. Alternatively, the micro switch can also be configured to release the trigger button 212 to trigger the micro switch to send a placement signal to an external display. Under this setting, the trigger button 212 is arranged on the lower end surface of the micro switch. When the material box 10 is placed on the main platform 100, the pressing portion 2211 bears the gravity of the material box 10 and moves in a direction away from the main platform 100 to drive the trigger portion 2212 to move in a direction away from the trigger button 212, so that the trigger portion 2212 no longer presses the trigger button 212, so that the trigger button 212 sends a placement signal to the external display; after the material box 10 is removed from the main platform 100, the pressing portion 2211 and the reset member 222 no longer bear the gravity of the material box 10, the reset member 222 returns to its original state, and drives the pressing portion 2211 and the trigger portion 2212 to move in a direction close to the main platform 100, and the trigger portion 2212 presses the trigger button 212 again. The specific triggering method is set according to actual needs. In this embodiment, it is set to release the trigger button 212 to trigger the micro switch to send a placement signal to the external display component.

[0043] In order to further improve the transmission effect and ensure the accuracy when triggering the micro switch, in this embodiment, the trigger portion 2212 is configured to be plate-shaped, and the extension direction of the trigger portion 2212 is perpendicular to the axis of the pressing portion 2211 .

[0044] Preferably, the reset member 222 is configured as a reset spring, one end of which is fixedly connected to the lower end of the pressing portion 2211, and the other end is fixedly connected to the lower end surface of the main platform 100 through the connecting plate 223. The connection strength and connection stability of the reset spring are improved through the connecting member 211, thereby ensuring the reset effect of the reset spring on the pressing member 221. When the material box 10 is placed on the main platform 100, the pressing member 221 and the end of the reset spring away from the connecting plate 223 move in a direction away from the main platform 100, so as to trigger the micro switch to send a placement signal to the external display, such as Figure 2 and Figure 3When the material box 10 is removed from the main platform 100, under the elastic force of the reset spring, the end of the reset spring away from the connecting plate 223 drives the pressing member 221 to move toward the main platform 100 until the reset spring returns to its original state. Figure 1 shown.

[0045] In order to further enhance the resetting effect of the resetting spring on the lower pressing member 221 and ensure the accuracy of detecting the presence or absence of the loading box 10 on the main platform 100, in this embodiment, the extending direction of the resetting spring is the same as the extending direction of the trigger portion 2212.

[0046] Preferably, the pressing assembly 220 further includes a reinforcing spring 224, which is arranged on the reset spring and fixedly connected to the lower end surface of the main platform 100. In this way, the elastic force of the reset spring is further enhanced, thereby ensuring the reset effect of the reset spring on the pressing member 221; at the same time, the service life of the reset spring and the detection mechanism 200 is extended. The number of reinforcing springs 224 can be set according to actual needs and is not specifically limited here.

[0047] Preferably, the detection mechanism 200 is also provided with a prompting member, which is in communication connection with the triggering member 210, and the prompting member can issue a prompt with reference to the placement state or idle state of the pressing member 221. In this way, after the pressing member 221 switches from the placement state to the idle state, the operator can place the material box 10 on the main platform 100 in time according to the prompting effect of the prompting member. The prompting member can be set as a light prompting member or a sound effect prompting member, which can prompt the operator of the current state of the pressing member 221 by emitting different sound effects or lights of different colors. The specific form of the prompting member is set according to actual needs and is not specifically limited here.

[0048] Preferably, a plurality of limiting seats 120 are arranged at intervals on the upper end surface of the main platform 100, and the plurality of limiting seats 120 cooperate with the upper end surface of the main platform 100 to form a limiting cavity for limiting the material box 10, and the detection channel 110 is arranged on the bottom wall of the limiting cavity. By setting the limiting cavity, the approximate area where the material box 10 is placed on the main platform 100 can be limited, so as to ensure that after the material box 10 is placed in the limiting cavity, the micro switch can be triggered timely and accurately through the lower pressing member 221.

[0049] Furthermore, a plurality of positioning posts 130 for positioning the material box 10 are arranged at intervals on the upper end surface of the main platform 100, and the plurality of positioning posts 130 are all located on the bottom wall of the limiting cavity. The plurality of positioning posts 130 cooperate with each other to precisely position the material box 10 placed on the upper end surface of the main platform 100, so as to further improve the convenience of silicon wafer processing and ensure the accuracy and timeliness of the trigger 210 when sensing the status of the material box 10 on the main platform 100.

[0050] Embodiment 2

[0051] Combination Figure 4 and Figure 5 As shown, the main platform 100, the pressing member 221 and the trigger member 210 in this embodiment are exactly the same as those in the first embodiment and will not be described again here. The only difference is that in this embodiment, the reset member 222 is configured as a tension spring, the pressing portion 2211 is configured as a rod, the tension spring is sleeved on the pressing portion 2211, and one end of the tension spring is fixedly connected to the middle part of the pressing portion 2211, and the other end is fixedly connected to the lower end surface of the main platform 100.

[0052] A connecting flange is provided in the middle of the pressing part 2211, and one end of the tension spring facing away from the main platform 100 is fixedly connected to the connecting flange, so as to reduce the difficulty of installing the tension spring and ensure the connection effect of the tension spring. In this way, after the material box 10 containing silicon wafers is placed on the main platform 100, under the gravity of the material box 10, the pressing part 221 as a whole moves in the direction away from the main platform 100 under the gravity of the material box 10. During the downward movement of the pressing part 221, the tension spring is stretched, and the pressing part 221 triggers the micro switch, which sends a placement signal to the external display. After the material box 10 is removed from the main platform 100, the pressing piece 221 no longer bears the gravity of the material box 10. At this time, the tension spring is no longer under force and begins to rebound autonomously, driving the pressing piece 221 to move toward the direction close to the main platform 100 until the tension spring returns to its original state. At this time, part of the pressing piece 221 passes through the detection channel 110 again and is exposed on the upper end surface of the main platform 100, so that after a new material box 10 is placed on the main platform 100, the pressing piece 221 can trigger the micro switch in a timely and accurate manner.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
