[0027] The present invention will be further described below in conjunction with the embodiments.

[0028] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0029] Example 1

[0030] like Figure 1 , Figure 2 and Figure 4As shown, the present invention provides a four-station loading device, which includes a mounting plate 1, a material placement mechanism 2 mounted on the mounting plate 1, a material taking robot for placing materials on the material placement mechanism 2 onto the device, and a control system; the material placement mechanism 2 includes a rotating material trough 21 mounted on the mounting plate 1 and connected to the control system, a lifting mechanism 22 connected to the control system for lifting the materials in the rotating material trough 21, and a material box 23 fixedly mounted on the lifting mechanism 22 on a side away from the rotating material trough 21;

[0031] The rotating material trough 21 includes a rotating table 211 located above the mounting plate 1, a first servo motor 212 fixedly mounted on the bottom surface of the mounting plate 1 and connected to the control system for driving the rotating table 211 to rotate, and a material trough 213 symmetrically mounted on the rotating table 211;

[0032] The lifting mechanism 22 includes a fixed plate 221 fixedly mounted on the bottom of the mounting plate 1, a limit plate 225 located just above the fixed plate 221 corresponding to the mounting plate 1, a lifting plate 223 located between the fixed plate 221 and the limit plate 225 and moving up and down, a lead screw 224 longitudinally penetrating the middle position of the lifting plate 223 and rotatably connected to the fixed plate 221 and the limit plate 225, and a second servo motor 222 fixedly mounted on the bottom surface of the fixed plate 221 and connected to the control system, the output shaft of the second servo motor 222 is fixedly connected to the lead screw 224; the lifting plate 223 is located above the mounting plate 1 and is threadedly connected to the lead screw 224; a lifting rod 226 for extending into the interior of the material trough 213 and contacting the material is fixedly mounted on the upper surface of the lifting plate 223;

[0033] A sliding groove 214 for the lifting rod 226 to move up and down is provided on one side of the two material placing grooves 213 away from each other and on one end of the rotating platform 211 away from each other;

[0034] The distance between the rotating platform 211 and the mounting plate 1 is at least greater than the thickness of the lifting rod 226 .

[0035] When in use, the second servo motor 222 is controlled to start, driving the lead screw 224 to rotate, so that the lead screw 224 drives the lifting plate 223 to move downward, and then drives the lifting rod 226 to move downward, so that the lifting rod 226 contacts the mounting plate 1; then two different materials are placed in the material trough 213 and the material box 23 respectively, and then the first servo motor 212 is controlled to start, driving the rotating table 211 to rotate, so that the material trough 213 on the rotating table 211 rotates and reverses, so that the material in the material trough 213 is located above the lifting rod 226; when loading, the second servo motor 222 is controlled to start, driving the lead screw 224 to rotate, so that the lead screw 224 drives the lifting plate 223 to move downward, and then drives the lifting rod 226 to move downward, so that the lifting rod 226 contacts the mounting plate 1; then, two different materials are placed in the material trough 213 and the material box 23 respectively, and then the first servo motor 212 is controlled to start, driving the rotating table 211 to rotate, so that the material in the material trough 213 is located above the lifting rod 226 The machine 222 drives the lead screw 224 to rotate, so that the lifting plate 223 moves upward on the lead screw 224, thereby driving the lifting rod 226 to lift the material in the material trough 213 upward, so that the material picking robot can pick up the material in the material trough 213; at the same time, after the material in the material trough 213 on one side of the rotating table 211 is taken out, the material can be piled in the material trough 213 on the other side. When the material is taken out, the lifting rod 226 is controlled to descend to the lowest point, and then the rotating table 211 is driven to rotate by controlling the second servo motor 212, so that the material trough 213 is turned, thereby achieving the purpose of alternating feeding.

[0036] It is worth mentioning that the device stacks the materials in the material trough 213, and uses the lifting rod 226 to drive the materials to move upward, so that the material picking robot can perform one-to-one grabbing, thereby achieving the purpose of material separation, and can realize alternating loading after the materials are taken. After the materials are taken, there is no need to stop the machine, and only the material trough on the other side needs to be reversed to load the materials again, which saves the time of stopping for loading and greatly improves the efficiency of product loading.

[0037] Further, such as Figure 2 and Figure 4 As shown, the lifting mechanism 22 also includes a first limit sensor 227 fixedly installed at the bottom of the limit plate 225 and connected to the control system, and a sensor sheet 2271 fixedly installed on the lifting plate 223 for contact sensing with the first limit sensor 227 .

[0038] When lifting the material, the second servo motor 222 drives the screw 224 to rotate, so that the screw 224 drives the lifting plate 223 to move upward. After the material is grabbed, the lifting plate 223 rises to the highest position. When the lifting plate 223 is lifted to the highest position, the sensor plate 2271 contacts the first limit sensor 227, thereby transmitting a trigger signal to the control system, and the control system controls the second servo motor 222 to rotate in the opposite direction, driving the screw 224 to rotate in the opposite direction, and then driving the lifting rod 226 to move downward, contact the mounting plate 1, and move to the bottom of the material trough 213.

[0039] Furthermore, Figure 2As shown, at least one guide column 228 penetrating through the lifting plate 223 is provided between the fixed plate 221 and the limiting plate 225 , and both ends of the guide column 228 are fixedly connected to the fixed plate 221 and the limiting plate 225 respectively, and the guide column 228 is slidably connected to the lifting plate 223 .

[0040] When the lead screw 224 rotates, if there is no guiding mechanism, the lifting plate 223 will directly rotate with the lead screw 224, affecting the lifting and lowering of the lifting plate 223. The lifting plate 223 is guided by the guide column 228 to prevent the lifting plate 223 from rotating with the lead screw 224, thereby ensuring the stability of the lifting and lowering operation of the lifting plate 223.

[0041] Further, if Figure 2 and Figure 4 As shown, a material sensor 2261 connected to a control system for determining whether there is material is fixedly mounted on the upper surface of one end of the lifting rod 226 away from the lifting plate 223 .

[0042] The material sensor 2261 can be a pressure sensor. When the lifting rod 226 is lifted upward and contacts the material, the material sensor 2261 contacts the material. At this time, the material sensor 2261 detects the pressure and sends the detected pressure signal to the control system, and starts the second servo motor 222 through the control system to lift the material.

[0043] It is worth mentioning that the use of a pressure sensor as the material sensor 2261 is only one form. The material sensor 2261 is a sensor for detecting whether there is material in the material trough 213, and is not limited to the use of a pressure sensor.

[0044] In addition, if Figure 1 and Figure 4 As shown, the material placing mechanism 2 further includes a second limit sensor 24 which is fixedly mounted above the corresponding material lifting rod 226 of the mounting plate 1 and is connected to the control system.

[0045] When the material is lifted, the position of the material is detected by the second limit sensor 24. When the material contacts the contact of the second limit sensor 24, the second limit sensor 24 sends a trigger signal to the control system, which controls the second servo motor 222 to engage the brake and stop rotating, thereby stopping the lifting of the material.

[0046] Example 2

[0047] Different from the embodiment 1, the feeding device further comprises a sealing mechanism 3 for the placing mechanism 2;

[0048] The sealing mechanism 3 includes an upper sealing box 31 fixedly mounted on the upper surface of the mounting plate 1 corresponding to the outer side of the rotating material trough 21 and the lifting mechanism 22, a lower sealing box 32 fixedly mounted on the bottom of the mounting plate 1 corresponding to the outer side of the second servo motor 222, and a movable cover 33 fixedly mounted on one side of the material box 23 for sealing the first opening on the top surface of the material box 23.

[0049] For moisture-proof materials (such as moisture-proof agents, humidity test cards, etc.), the equipment needs to be isolated from the outside air to minimize the contact between the outside air and the moisture-proof materials to avoid exposure of the materials to the air and causing them to become damp.

[0050] Specifically, Figure 3 and Figure 4 As shown, the top surface of the upper sealing box 31 has a second opening for taking materials, and a flip cover 312 is provided at a position corresponding to the second opening on the upper sealing box 31. A driving mechanism 313 connected to the control system for driving the flip cover 312 to flip is fixedly installed on one side of the upper sealing box 31 corresponding to the flip cover 312.

[0051] A second opening is provided on the upper sealing box 31, and a flip cover 312 is provided at a corresponding position of the second opening. When it is necessary to take materials, the control system controls the driving mechanism 313 to drive the flip cover 312 to reverse and open, so that the material taking robot can take the materials on the material placing mechanism 2 and place them on the working equipment.

[0052] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the movable cover 33 includes a covering plate 331 slidably mounted at the first opening position of the material box 23 and a slide cylinder 332 fixedly mounted on one side of the material box 23 and connected to the control system for driving the covering plate 331 to move. One end of the covering plate 331 is fixedly connected to the slide of the slide cylinder 332.

[0053] A movable cover 331 is provided at the first opening of the material box 23. When taking materials, a control system may control the slide cylinder 332 to drive the movable cover 331 to move and open on the material box 23. When the taking of materials is completed, the slide cylinder 332 pushes the movable cover 331 to close, thereby effectively reducing the time that the materials in the material box 23 are exposed to the air and reducing the possibility of the materials getting damp.

[0054] Further, such as Figure 3 As shown, a loading door 311 is hingedly connected to one side surface of the upper sealing box 31 .

[0055] A loading door 311 is provided on one side of the upper sealing box 31 . After the materials in the material trough 213 at one end of the rotating table 211 are taken out and turned, the loading door 311 is opened to stack the materials, so that adding materials in the material trough 213 is more convenient.

[0056] Furthermore, a visual window 314 is embedded on the side surface of the upper sealing box 31 adjacent to the loading door 311 .

[0057] The viewing window 314 is made of glass or acrylic plate and has good light transmittance. The operation of the equipment in the upper sealing box 31 can be observed through the viewing window 314, which is convenient for operators to observe and monitor the equipment.

[0058] It should be noted that the material-grabbing robot and control system recorded in this scheme do not belong to the technologies that need to be protected by this scheme. For example, the material-grabbing robot can be a robotic arm and a clamp or a robotic arm and a suction cup that cooperate to grab materials, and it is controlled by the control system; and the control technology of the control system for intelligent devices are all existing technologies that can be realized.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
