DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The embodiment of the utility model provides an automatic loading and unloading device, including an adsorption module 4 for grabbing materials and an up-and-down motion module 3 for driving the adsorption module 4 to move up and down, the adsorption module 4 has a pneumatic material shaking mechanism 13 and a vacuum suction cup 14 for sucking materials, the vacuum suction cup 14 is arranged at the end of the pneumatic material shaking mechanism 13, and the up-and-down motion module 3 has a slide cylinder 6, and the slide cylinder 6 drives the adsorption module 4 to move up and down. In this embodiment, the adsorption module 4 is used to grab the material, and the grabbing method can be a vacuum adsorption method, such as using the vacuum suction cup 14 to adsorb the material, and then using the up-and-down motion module 3 to drive the adsorption module 4 to move up and down to complete the grabbing of the material. When it is found that the material is sticky, for example, two carriers are stacked together, a pneumatic shaking mechanism can be used to quickly and high-frequency shake, so as to separate the carriers. Further, with the up-and-down high-frequency expansion and contraction of the slide cylinder 6, a better peeling effect can be achieved. The pneumatic shaking mechanism, i.e., a pneumatic vibrator, is a prior art, and its specific working principle will not be described in detail here. Of course, in addition to using a pneumatic shaking mechanism, a small slide cylinder 6 can also be used here to install the vacuum suction cup 14, and shaking at multiple positions can also be achieved to improve the peeling effect.

[0022] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the adsorption module 4 also includes a width adjustment structure 11 for adjusting the range of the material to be grabbed, and the width adjustment structure 11 is connected to the slide cylinder 6. In this embodiment, the width adjustment structure 11 is designed so that the automatic loading and unloading device is suitable for grabbing materials of any size and model. For example, if the format of the carrier plate is relatively large or relatively small, the width adjustment structure 11 can be used to adjust the range of the material to be grabbed. Preferably, the width adjustment structure 11 includes at least two adjustment plates and an adsorption rod arranged on the adjustment plate, and the adsorption rod is provided with a plurality of pneumatic material shaking mechanisms 13. The above-mentioned width adjustment structure 11 is refined, and it has a translationally movable adjustment plate. When the adjustment plate is moved, the adsorption rod thereon will also move accordingly, thereby adjusting the spacing between adjacent adsorption rods, thereby achieving width adjustment. Preferably, the pneumatic shaking mechanism is detachably mounted on the adsorption rod, so that the number of pneumatic shaking mechanisms can be designed according to needs. Preferably, the pneumatic shaking mechanism is movably arranged on the adsorption rod, so that the position of the pneumatic shaking mechanism can be adjusted according to needs. Here, an L-shaped connecting rod and a locking nut can be used to cooperate to achieve the connection between the pneumatic shake mechanism and the adsorption rod. The vertical rod of the L-shaped connecting rod has a threaded hole, and the locking nut fixes the vertical rod to the adsorption rod through the threaded hole. The horizontal rod of the L-shaped connecting rod has an installation position for the installation of the pneumatic shake mechanism.

[0023] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The adsorption module 4 further includes a negative pressure mechanism, and the negative pressure mechanism is provided with a negative pressure gauge 12. In this embodiment, the adsorption module 4 can use a negative pressure mechanism to provide a vacuum adsorption force, and use an air pipe to communicate with the vacuum suction cup 14. The negative pressure gauge 12 can adjust the pressure and display it.

[0024] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the up-and-down motion module 3 further comprises a solenoid valve 7 for controlling the movement of the slide cylinder 6. In this embodiment, the solenoid valve 7 can be used to control the telescopic movement of the slide cylinder 6.

[0025] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the device also includes a detection module 2 for detecting the adsorption state of the adsorption module 4. In the present embodiment, the adsorption state of the adsorption module 4 can be detected by the detection module 2. Preferably, the detection module 2 includes an ultrasonic sensor 8 and a color sensor 10. The detection module 2 also includes a horizontal sliding cylinder 9 for driving the ultrasonic sensor 8 to move. There are multiple ultrasonic sensors 8 and color sensors 10. Specifically, when the slide cylinder 6 descends, the vacuum suction cup 14 adsorbs the product, the slide cylinder 6 rises, and the color sensor works to confirm whether the adsorbed product is a carrier or a separator. If the adsorbed product is a separator, the separator is placed in the separator bin. If the adsorbed product is a carrier, the horizontal slide cylinder 6 extends, and the ultrasonic sensor 8 works to detect whether the carrier is sticky. The ultrasonic sensor 8 and the color sensor 10 are both existing sensors, which will not be introduced here. When it is found that the carrier is sticky, the pneumatic shaking mechanism is turned on and off at high frequency and the slide cylinder 6 shakes up and down at high frequency to peel off the sticky carrier, and then place the carrier. If there is no sticking, the carrier is placed directly.

[0026] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The device further includes a horizontal transfer belt module 1 for driving the vertical motion module 3 to move horizontally. In this embodiment, the horizontal transfer belt module 1 includes a linear guide rail 5, the purpose of which is to send the vertical motion module 3 to the location of the material. Then, after grabbing the material, the linear guide rail 5 is used to send the material to the paper separation bin, the board carrier bin, etc., so as to realize fully automatic loading and unloading.
