Figure 7 FIG. 3 is a structural diagram of the positioning device 300 according to an embodiment of the present disclosure from another angle.

[0069] like Figures 1 to 7 As shown, the loading system of the present disclosure includes components such as a suction device 100 , a motion platform 200 , and a positioning device 300 .

[0070] In a preferred embodiment, the motion platform 200 can be a three-dimensional motion platform, for example, a three-dimensional motion platform including three motion directions (X, Y, and Z). Thus, the motion platform 200 can generate three-dimensional motion and move the suction device 100 from the material collection position to the material loading position. In the material collection position, the suction device 100 can pick up the workpiece positioned by the positioning device 300, and in the material loading position, the suction device 100 can release the workpiece to the automated production line.

[0071] like Figures 2 to 4 As shown, the suction device 100 of the present disclosure may include: a fixing member 110, a driving device 120, a movable member 130, a suction assembly 140 and a positioning assembly.

[0072] In actual use, the fixing part 110 of the present invention can be fixed to the end of a robotic arm or other parts, so that the suction device 100 of the present invention can be moved to the suction position by the robotic arm. After the suction device 100 sucks the workpiece to be sucked at the suction position, the suction device 100 of the present invention can be moved to the release position by the robotic arm, and then the sucked workpiece can be released.

[0073] The driving device 120 is disposed on the fixed member 110, wherein the driving device 120 is used to drive the movable member 130 to move so that the movable member 130 can approach or move away from the fixed member 110. Specifically, the movable member 130 of the present disclosure is located below the fixed member 110. When the movable member 130 moves upward, it can approach the fixed member 110. Correspondingly, when the movable member 130 moves downward, it moves away from the fixed member 110.

[0074] In the present disclosure, a guide hole is formed on the fixing member 110 , and a guide post 160 is installed on the movable member 130 . The guide post 160 is slidably disposed in the guide hole.

[0075] like Figure 2 As shown, the fixing member 110 of the present disclosure is provided with four guide holes, which are respectively located at the four corners of the fixing member 110. Accordingly, the number of the guide posts 160 is also set to four, which are respectively provided in one-to-one correspondence with the guide holes.

[0076] Moreover, a limiting device 170 is provided at the upper end of the guide post 160, and the limiting device 170 is used to limit the maximum moving distance of the guide post 160 in the downward moving direction. In other words, by the setting of the limiting device 170, the guide post 160 will not disengage from the guide hole.

[0077] In the present disclosure, a linear bearing is provided in the guide hole, and the guide column 160 can be slidably provided in the linear bearing. The limiting device 170 cooperates with the linear bearing, that is, the limiting device 170 can stop on the linear bearing to limit the maximum movement distance of the guide column 160 in the downward movement direction.

[0078] In one embodiment, a center hole is opened on the fixing member 110, and the driving device 120 can be a cylinder. At this time, the cylinder body of the cylinder is fixed to the upper surface of the fixing member 110, and the piston rod of the cylinder passes through the center hole of the fixing member 110 and is fixedly connected to the movable member 130.

[0079] The movable member 130 is provided with a through hole; the through hole is used for the suction assembly 140 to pass through. Specifically, the number of the through holes can be the same as the number of the suction assembly 140. In a preferred embodiment, Figure 3 As shown, the number of the through holes is 8, and accordingly, the number of the suction components 140 is also 8.

[0080] At the same time, since the suction device 100 of the present disclosure can suck two workpieces at a time, accordingly, when the suction device 100 can only suck one workpiece, the number of through holes of the movable part 130 is four, and accordingly, the number of suction assemblies 140 is also set to four.

[0081] The suction assembly 140 is arranged on the fixed part 110, one end of which passes through the through hole of the movable part 130 and is located below the movable part 130; in a specific embodiment, the suction assembly includes a joint 141 and a suction cup 142, wherein the joint 141 is fixed to the fixed part 110, for example, a threaded hole is provided on the fixed part 110, and the outer surface of the joint 141 is provided with an external thread, so that the joint 141 is fixed in the threaded hole of the fixed part 110 by a threaded connection.

[0082] The connector 141 is connected to one end of the bellows, and the suction cup 142 is connected to the other end of the bellows. Thus, when the suction cup 142 contacts and absorbs the workpiece to be absorbed, the length of the bellows will become shorter due to the negative pressure in the bellows, thereby applying a pulling force to the workpiece through the suction cup 142. This pulling force will cause the workpiece to be tightly attached to the movable part 130 through the positioning assembly described below.

[0083] The positioning assembly is disposed on the lower surface of the movable member 130 , and the workpiece to be sucked is positioned by the positioning assembly.

[0084] In a specific embodiment, the positioning assembly includes: a positioning boss 151, one end of the positioning boss 151 is arranged on the lower surface of the movable part 130, and the other end of the positioning boss 151 has a preset distance from the lower surface of the movable part 130, so that when the suction cup 142 sucks the workpiece, the workpiece can rest on the positioning boss 151, so that the position of the workpiece in the height direction (Z direction) is accurately defined.

[0085] In a preferred embodiment, four positioning bosses 151 are provided, each located at a corner of the workpiece to be sucked. In other words, for sucking one workpiece, four positioning bosses 151 are provided. If the suction device 100 is capable of sucking two workpieces simultaneously, eight positioning bosses 151 may be provided.

[0086] In addition, the positioning assembly includes a floating positioning member 152, which is configured to float relative to the movable member 130 and cooperate with a positioning hole on the workpiece to be sucked to achieve positioning of the workpiece. In a preferred embodiment, the floating positioning member 152 can be a floating positioning pin, which can adopt a structure known in the art and will not be described in detail in this disclosure.

[0087] In a preferred embodiment, two floating positioning members 152 are provided. The positions of the two floating positioning members 152 can be set according to the positions of the positioning holes on the workpiece, thereby positioning the workpiece in the X and Y directions through the provision of the two floating positioning members 152.

[0088] In the prior art, after the workpiece is transferred to the carrier, a secondary positioning mechanism cannot be added due to the small space in the carrier and the need for the carrier to circulate. The suction device disclosed in the present invention uses two positioning pin holes with a diameter of 1.6 mm on the workpiece to position the workpiece, thereby improving the positioning efficiency during the workpiece transfer process.

[0089] When the suction device of the present disclosure is in use, the drive mechanism 120 operates to drive the movable member 130 downward toward the workpiece. Before the suction cup 142 contacts the product, the floating positioning member 152 is inserted into the positioning hole of the workpiece, thereby positioning the workpiece and correcting its X and Y positions. Furthermore, because the floating positioning member 152 has a certain amount of vertical movement, it will not damage the workpiece even if the movable member 130 continues to move downward.

[0090] Then, as the movable member 130 continues to move downward, the positioning boss 151 can contact the workpiece to be sucked before suction, positioning the workpiece, and then the suction assembly 140 can suck it. On the other hand, before suction, the positioning boss 151 can also not contact the workpiece, and through the suction assembly 140 sucking the workpiece, the workpiece can be moved in the Z-axis direction. At this time, the workpiece will also be closely attached to the positioning boss 151. Therefore, the provision of the positioning boss 151 can ensure the position of the workpiece on the Z-axis. Moreover, the use of multiple positioning bosses 151 can ensure that the workpiece has a flat posture during transfer, and will not cause lateral deviation due to different suction cup compression amounts.

[0091] Moreover, when debugging the picking point, align the floating positioning member 152 with the calibration device (the picking positioning pin of the product) on the picking platform, and then control the driving device 120 to move until the suction cup sucks up the product and the positioning boss also contacts the product, thereby completing the debugging of the picking point.

[0092] When debugging the discharge point, align the floating positioning pin with the calibration device on the discharge platform (the product's discharge positioning pin), then control the drive device 120 to move and press the product into the positioning pin on the discharge platform. The discharge point is then debugged.

[0093] During use, if the material pickup or discharge point is offset, the relative position of the floating locating member 152 and the material pickup positioning pin or the material discharge positioning pin can be adjusted to correct the offset. Thus, when the suction device of the present disclosure is in use, the floating locating pin can provide a certain position correction function for the product, ensuring stable operation of the suction device of the present disclosure. Furthermore, the suction device of the present disclosure is very convenient when debugging points, and can be checked using the floating locating member 152 as a reference, greatly reducing debugging time and improving production efficiency.

[0094] The suction cup gripper in the prior art has a relatively soft suction cup and different compression levels, which results in a certain amount of yaw during the gripper's movement after picking up the material, leading to poor pick-up and place accuracy. The suction device disclosed herein uses floating positioning elements to limit the product's X and Y positions, while positioning bosses 151 limit the product's Z position. This allows the suction device disclosed herein to achieve high pick-up and place accuracy and strong stability.

[0095] Furthermore, the existing suction cup gripper lacks a visual reference, resulting in a long time to adjust the position, poor position accuracy, and difficulty visually identifying any position deviations. The suction device disclosed herein can use a floating positioning element as a reference, significantly reducing the time required to adjust the position, and allowing for intuitive visualization of any position deviations, thereby improving production efficiency.

[0096] like Figures 5 to 7 As shown, the positioning device 300 of the present disclosure may include: a frame 310, a positioning plate 320, a first driving assembly 330, a first positioning column 340, a second driving assembly 350, and a second positioning column 360.

[0097] The positioning plate 320 is disposed on the frame 310 and supported by the frame 310. In the present disclosure, the frame 310 is located below the positioning plate 320.

[0098] The positioning plate 320 is provided with a plurality of positioning slots 321 for receiving a workpiece to be positioned. In a preferred embodiment, the length of the positioning plate 320 is a first direction described below, and the width of the positioning plate 320 is a second direction described below. In this case, the first direction and the second direction are different. More preferably, the first direction and the second direction are perpendicular or substantially perpendicular.

[0099] In a specific embodiment, the number of positioning grooves 321 can be two, and the two positioning grooves 321 are arranged side by side. Preferably, the positioning grooves 321 are formed as substantially rectangular grooves and have a certain depth. The length direction of the positioning grooves 321 can be parallel or substantially parallel to the width direction of the positioning plate 320.

[0100] A first hole structure 322 and a second hole structure 323 are provided on the positioning plate 320. The first hole structure 322 is an elongated hole, and the length direction of the first hole structure 322 is the first direction; the second hole structure 323 is an elongated hole, and the length direction of the second hole structure 323 is the second direction. At least part of the first hole structure 322 and / or the second hole structure 323 is located in the positioning groove 321.

[0101] More preferably, the positioning groove 321 includes a first positioning side wall 324 and a second positioning side wall 325, wherein the first positioning side wall 324 and the second positioning side wall 325 are two adjacent side walls of the positioning groove 321; accordingly, the first hole structure 322 is arranged near the side wall opposite to the first positioning side wall 324 of the positioning groove 321, and the second hole structure 323 is arranged near the side wall opposite to the second positioning side wall 325 of the positioning groove 321.

[0102] The first drive assembly 330 is disposed on the frame 310 and is configured to drive the first positioning column 340 to move in a first direction. Accordingly, the first positioning column 340 can push the workpiece toward the first positioning sidewall 324, positioning the workpiece by the first positioning sidewall 324. Alternatively, positioning in the first direction can be achieved by the first positioning column 340 and the first positioning sidewall 324. In a preferred embodiment, the first drive assembly 330 can be a pneumatic cylinder.

[0103] When the first positioning post 340 approaches the workpiece to be positioned, it can push the workpiece toward the first positioning sidewall 324 and position the workpiece by the first positioning sidewall 324. In the opposite working process, when the first positioning post 340 moves away from the workpiece to be positioned, it can release the workpiece.

[0104] In the present disclosure, the first positioning column 340 is slidably disposed in the first hole structure 322 , and the upper end of the first positioning column 340 protrudes from the bottom wall of the positioning groove 321 of the positioning plate 320 , thereby enabling the first positioning column 340 to contact the workpiece and push the workpiece to move.

[0105] The second drive assembly 350 is mounted on the frame 310 and is configured to drive the second positioning column 360 to move in the second direction. The second positioning column 360 is configured to push the workpiece toward the second positioning sidewall 325 and to be positioned by the second positioning sidewall 325. In other words, positioning in the second direction is achieved through the second positioning column 360 and the second positioning sidewall 325. In a preferred embodiment, the second drive assembly 350 may be a pneumatic cylinder.

[0106] When the second positioning post 360 approaches the workpiece to be positioned, it can push the workpiece toward the second positioning sidewall 325 and position the workpiece by the second positioning sidewall 325. In the opposite working process, when the second positioning post 360 moves away from the workpiece to be positioned, it can release the workpiece.

[0107] Two or more first positioning posts 340 are disposed near each positioning slot 321 , and / or two or more second positioning posts 360 are disposed near each positioning slot 321 ; in a specific embodiment, the number of first positioning posts 340 and second positioning posts 360 corresponding to each positioning slot 321 is both two.
