Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In some application descriptions, "plurality" means two or more, unless otherwise specifically defined.

[0038] The present application provides a sorting mechanism that can sort scattered workpieces, for example, the workpieces can be used to sort chips (grains) and the like.

[0039] See Figure 1 A sorting mechanism includes a vibration assembly and a receiving assembly. The vibration assembly 100 is used to screen, orient, and sort scattered workpieces before transporting them. The receiving assembly 200 is used to receive the workpieces transported by the vibration assembly 100.

[0040] The vibration assembly may include a vibration disk 110 and a direct vibration structure 120, one end of which is connected to the vibration disk 110. The vibration disk 110 is used to screen and orient scattered workpieces and then transfer them to the direct vibration structure 120 for sorting. The direct vibration structure 120 is used to drive the workpieces to move.

[0041] Combine Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The material receiving assembly 200 includes a material receiving platform 210 and a material receiving driving structure 220 .

[0042] The material receiving platform 210 is used to dock with an end of the direct vibration structure 120 away from the vibration plate 110 to receive the workpiece transmitted by the direct vibration structure 120 .

[0043] The receiving platform 210 is provided with air holes 211 , which can absorb the workpiece. That is, after the receiving platform 210 receives the workpiece transmitted by the direct vibration structure 120 , the workpiece can be absorbed through the air holes 211 to fix the workpiece on the receiving platform 210 .

[0044] The material receiving driving structure 220 is drivingly connected to the material receiving platform 210 to drive the material receiving platform 210 to move closer to or away from the direct vibration structure 120 .

[0045] During material receiving, the receiving drive structure 220 can drive the receiving platform 210 to move toward the direct vibration structure 120, so that the receiving platform 210 can receive the workpiece transferred by the direct vibration structure 120. For example, the receiving drive structure 220 can drive the receiving platform 210 toward the direct vibration structure 120 until the receiving platform 210 docks with the end of the direct vibration structure 120 that is away from the vibration plate 110.

[0046] After the workpieces are received, the workpiece receiving driving structure 220 can drive the workpiece receiving platform 210 to move away from the direct vibration structure 120 , so that the workpieces on the workpiece receiving platform 210 are separated from the direct vibration structure 120 .

[0047] That is, in the sorting mechanism of the present application, the vibration disk 110 and the direct vibration structure 120 of the vibration assembly 100 screen, orient, and sort the scattered workpieces before transmission. The receiving drive structure 220 of the receiving assembly 200 drives the receiving platform 210 to move toward or away from the direct vibration structure 120, so that the receiving platform 210 can receive the workpieces transmitted by the direct vibration structure 120. After receiving the workpieces, the receiving platform 210 can drive the workpieces to move away from the direct vibration structure 120, thereby achieving workpiece sorting. The above-mentioned sorting mechanism has a simple sorting method, a simple structure, and low cost.

[0048] Further, combined with Figures 5 to 8 In some embodiments, the receiving platform 210 may also be provided with a positive-pressure gas channel 212 and a negative-pressure gas channel 213, each of which is in communication with the air holes 211. The positive-pressure gas channel 212 can supply positive-pressure gas to the air holes 211, thereby blowing away the workpiece received by the receiving platform 210. The negative-pressure gas channel 213 can supply negative-pressure gas to the air holes 211, thereby adsorbing the workpiece received by the receiving platform 210, thereby securing the workpiece and facilitating its removal from the direct vibration structure 120.

[0049] Specifically, when the receiving platform 210 receives a normal workpiece, the negative pressure gas channel 213 can provide negative pressure gas to the air hole 211, so that the air hole 211 can adsorb the workpiece, thereby facilitating the receiving drive structure 220 to drive the receiving platform 210 to move away from the direct vibration structure 120.

[0050] When the receiving platform 210 receives waste workpieces, the positive pressure gas channel 212 can provide positive pressure gas to the air holes 211, so that the air holes 211 can blow away the workpieces on the receiving platform 210 to avoid affecting the receiving platform 210 to receive materials again.

[0051] Furthermore, the receiving assembly 200 further includes a waste bin 230, which is arranged corresponding to the landing position of the workpieces blown out from the receiving platform 210. When the receiving platform 210 blows the workpieces away from the receiving platform 210 through the air holes 211, the workpieces can fall into the waste bin 230 for collection.

[0052] Further, combined with Figure 3 and Figure 4 In some embodiments, to ensure the stability and accuracy of the movement of the receiving platform 210, the receiving assembly 200 may further include a guide member 240. The receiving platform 210 is connected to the guide member 240, and the guide member 240 guides the receiving platform 210 during its movement. The guide member 240 may be a guide rail, for example, a cross guide rail.

[0053] See Figure 2 The material receiving assembly 200 may further include a conversion structure 250, which is connected to the material receiving platform 210 and the material receiving drive structure 220 respectively, and the conversion structure is used to convert the rotational motion of the material receiving drive structure 220 into the horizontal motion of the material receiving platform 210.

[0054] It can be understood that when the material receiving component 200 includes a conversion structure 250, the material receiving drive structure 220 can adopt a device that can drive rotation. The conversion structure 250 converts the rotational motion of the material receiving drive structure 220 into the linear motion of the material receiving platform 210. This method can increase the speed of the material receiving platform 210 moving toward or away from the direct vibration structure 120, and this method can also make the structure of the material receiving component 200 more compact and occupy less space.

[0055] Specifically, in some embodiments, the conversion structure 250 may include an eccentric wheel 251 and a transmission member 252. The material receiving drive structure 220 is driven and connected to the eccentric wheel 251 to drive the eccentric wheel 251 to rotate. The transmission member 252 is connected to the material receiving platform 210. A receiving groove 253 is provided on the transmission member 252. The eccentric wheel 251 is located in the receiving groove 253 and can contact the two side walls of the receiving groove 253 respectively. When the eccentric wheel 251 rotates, it can drive the material receiving platform 210 to approach or move away from the direct vibration structure 120 through the transmission member 252. The material receiving drive structure 220 can be a rotary motor, such as a servo motor.

[0056] It can be understood that the material receiving drive structure 220 drives the eccentric wheel 251 to rotate within the receiving groove 253. During the rotation process, the eccentric wheel 251 drives the transmission member 252 to move by contacting the side walls of the receiving groove 253. For example, when the eccentric wheel 251 rotates in a first direction, the eccentric wheel 251 contacts the side walls of the receiving groove 253 that are close to the direct vibration structure 120 and drives them to move, causing the transmission member 252 to move toward the direct vibration structure 120; when the eccentric wheel 251 rotates in a second direction opposite to the first direction, the eccentric wheel 251 contacts the side walls of the receiving groove 253 that are away from the direct vibration structure 120 and drives them to move, causing the transmission member 252 to move away from the direct vibration structure 120.

[0057] Furthermore, in order to facilitate the follower wheel 254 to drive the transmission member 252 to move, and at the same time ensure the stability of the movement of the transmission member 252, the conversion structure 250 may also include a follower wheel 254, the follower wheel 254 is arranged on the eccentric wheel 251, the follower wheel 254 is located in the accommodating groove 253, and respectively contacts the two side walls of the accommodating groove 253 to drive the transmission member 252 to move.

[0058] Specifically, the material receiving drive structure 220 drives the eccentric wheel 251 to rotate, and the eccentric wheel 251 drives the follower wheel 254 to rotate. When the follower wheel 254 rotates, it can drive the transmission member 252 to move and can move in the accommodating groove 253 in a direction perpendicular to the transmission member 252. The follower wheel 254 is slidingly connected to the side wall of the accommodating groove 253 in the accommodating groove 253.

[0059] See Figures 6 to 8 In order to facilitate the provision of an air hole 211 and a positive-pressure gas channel 212 and a negative-pressure gas channel 213 connected to the air hole 211 on the material receiving platform 210, the material receiving platform 210 includes a mounting part 214 and a material receiving part 215 arranged on the mounting part 214, and the material receiving part 215 is provided with an air hole 211 and a positive-pressure gas channel 212 and a negative-pressure gas channel 213.

[0060] The mounting member 214 is respectively provided with a first air channel 216 and a second air channel 217 , and one end of the first air channel 216 and the second air channel 217 is respectively installed with an air pipe joint 218 , the other end of the first air channel 216 is connected to the positive pressure gas channel 212 , and the other end of the second air channel 217 is connected to the negative pressure gas channel 213 .

[0061] In order to facilitate the positive pressure gas channel 212 and the negative pressure gas channel 213 to be connected to the air hole 211 at the same time, and the positive pressure gas channel 212 is connected to the first air channel 216, and the negative pressure gas channel 213 is connected to the second air channel 217

[0062] The external gas generating device can pass the gas into the air hole 211 through the air pipe connector 218. The air pipe connector 218 is set on the mounting member 214, and then the gas is transmitted to the positive pressure gas channel 212 and the negative pressure gas channel 213 on the material receiving member 215 through the first air channel 216 and the second air channel on the mounting member 214, so that corresponding gas is generated at the air hole 211. This method can facilitate the installation of the air pipe connector 218 with sufficient space, and at the same time can avoid the air pipe connector 218 from interfering with the direct vibration structure 120, the workpiece, etc.

[0063] Optionally, when the material receiving platform 210 includes a mounting member 214 and a material receiving member 215 arranged on the mounting member 214, the material receiving platform 210 can be connected to the guide member 240 through the mounting member 214, and the material receiving platform 210 can be connected to the transmission member 252 through the mounting member 214.

[0064] Furthermore, the material receiving member 215 may further include a main body 2151 and a material receiving portion 2152 protruding from the main body 2151 toward the direct vibration structure 120. The main body 2151 is connected to the mounting member 214, and the material receiving portion 2152 is provided with air holes 211. This structure facilitates the movement of the material receiving member 215 via the material receiving portion 2152 to the area where the direct vibration structure 120 outputs the workpiece for receiving the workpiece, thereby preventing the entire connecting member from being too close to the direct vibration structure 120 and interfering with the direct vibration structure 120.

[0065] See Figure 2 and Figure 3 The material receiving assembly 200 may also include a position adjustment structure 260, which is respectively connected to the material receiving platform 210 and the material receiving drive structure 220 to drive the material receiving platform 210 and the material receiving drive structure 220 to move synchronously in the horizontal and vertical directions to adjust the position of the material receiving platform 210 and ensure that the material receiving platform 210 can accurately receive the workpiece transmitted by the direct vibration structure 120.

[0066] For example, in some embodiments, the position adjustment structure 260 may include a base 261, a first movable member 262 and a second movable member 263. The first movable member 262 can be movably set on the base 261 along a first horizontal direction, and the second movable member 263 can be movably set on the first movable member 262 along a second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction, and the second horizontal direction is the same as the moving direction of the material receiving platform 210. The material receiving platform 210 and the material receiving drive structure 220 can be movably set on the second movable plate along the vertical direction through the mounting seat 267. The first movable member 262 is connected to the base 261 through a first adjusting screw 264 to change the position of the first movable member 262. The second movable member 263 is connected to the first movable member 262 through a second adjusting screw 265 to change the position of the second movable member 263. The second movable member 263 is connected to the mounting seat 267 through a third adjusting screw 266 to change the position of the mounting seat 267.

[0067] Furthermore, an elastic member 268 may be provided between the mounting seat 267 and the second movable member 263 to eliminate the gap between the mounting seat 267 and the second movable member 263 and ensure the accuracy of the vertical movement of the mounting seat 267 .

[0068] See Figure 1 The sorting mechanism may further include a first sensor 300, which is disposed above the direct vibration structure 120 or the receiving platform 210 and is used to detect the workpiece. For example, the first sensor 300 may be a detection camera to detect whether the workpiece is defective or waste.

[0069] When the workpiece is defective or waste, positive pressure gas can be generated at the air hole 211 to blow the workpiece on the receiving platform 210 into the waste box 230; when the workpiece is good, negative pressure gas can be generated at the air hole 211 to adsorb and fix the workpiece on the receiving platform 210.

[0070] See Figure 2 The sorting mechanism may further include a second sensor 400. The first sensor 300 may be located on the side of the area receiving the workpiece in the receiving platform 210 to detect whether there is a workpiece on the receiving platform 210. For example, the second sensor 400 may be a through-beam sensor.

[0071] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of some applications should be included in the scope of protection of some applications.
