Description

Technical Field

[0001] This application relates to the field of product conveying technology, and in particular to workpiece transfer devices and product conveying equipment. Background Technology

[0002] With the development of intelligent manufacturing, product conveyor lines are widely used in various industrial fields. In automated production processes, workpieces on the conveyor line are transferred to designated workstations via workpiece transfer devices. In related technologies, workpiece transfer devices often employ a pushing mechanism to push the workpiece off the conveyor line; typically, the pushing direction of the pushing mechanism is perpendicular to the workpiece conveying direction. To reduce the risk of workpiece tipping due to uneven force during transfer, the conveyor speed needs to be reduced. This, however, affects the workpiece transfer efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a workpiece transfer device and product conveying equipment to address the problem that the conveying speed of the conveyor line is reduced when the pushing mechanism pushes the workpiece along the conveying direction perpendicular to the conveyor line, resulting in low workpiece transfer efficiency.

[0004] On the one hand, this application provides a workpiece transfer device for transferring workpieces on a conveyor line, comprising:

[0005] The bearing section is located on one side of the conveyor line in the conveying direction and is used to receive workpieces from the conveyor line;

[0006] The transfer assembly includes a transfer section, which is movably disposed relative to a support section. The transfer section drives a workpiece located at a preset position on a conveyor line to slide along a preset trajectory onto the support section. The preset trajectory includes at least a first trajectory, which is arc-shaped and has a starting point at a preset position.

[0007] In one embodiment, the transfer unit is rotatably disposed relative to the support unit about a rotation axis, and the end of the transfer unit away from the rotation axis drives the workpiece to move synchronously so that the workpiece slides to the loading position of the support unit, and the end point of the first trajectory is the loading position.

[0008] In one embodiment, the preset trajectory further includes a second trajectory, which is arc-shaped and coaxial with the first trajectory, and has the same radius. The starting point of the second trajectory is the loading position, and the end of the transfer part away from the rotation axis drives the workpiece to move synchronously so that the workpiece slides along the second trajectory to the target position of the bearing part. The target position is the end point of the second trajectory.

[0009] In one embodiment, the end of the transfer section away from the rotation axis has a pressing structure. When the workpiece is in a preset position, the pressing structure contacts at least a portion of the workpiece and pushes the workpiece to slide along a first trajectory to the loading position.

[0010] In one embodiment, the pressing structure includes a pressing groove, which opens on the side away from the rotation axis and extends through the transfer portion along the extension direction of the rotation axis.

[0011] In one embodiment, the transfer unit includes a turntable, which is rotatably mounted on the bearing unit about a rotation axis. A pressure groove is provided at the periphery of the turntable, and multiple pressure grooves are provided, which are distributed at intervals along the circumference of the turntable.

[0012] In one embodiment, the workpiece transfer device further includes:

[0013] A limiting part is provided on the bearing part and is located outside the transfer part. The limiting part extends circumferentially along the rotation axis and cooperates with the pressing groove to restrict the workpiece from leaving the pressing groove.

[0014] In one embodiment, the limiting part includes a first arc segment and a second arc segment connected to each other. The first arc segment is located above the conveyor line, and the second arc segment is located above the bearing part. A feeding area is formed between the first arc segment and the bearing part. A feeding port is formed at the end of the feeding area away from the second arc segment so that the workpiece can enter the feeding area.

[0015] In one embodiment, the carrier includes a mating side that is in the same direction as the conveyor line, and the workpiece transfer device further includes:

[0016] The guide section is located at the end of the first arc segment away from the second arc segment. The extension direction of the guide section is the same as the extension direction of the mating side. A feed inlet is formed between the guide section and the bearing section.

[0017] In one embodiment, the height of the first arc segment is higher than the height of the upper surface of the bearing portion, so that the first arc segment avoids the fixture on the conveyor line where the workpiece is placed.

[0018] In one embodiment, the support portion is provided with a discharge port, which is the end point of a preset trajectory. When the transfer portion drives the workpiece to slide to the discharge port, the workpiece disengages from the support portion through the discharge port; or...

[0019] The workpiece transfer device also includes a lifting unit, which has a lifting end that is vertically movable, and a load-bearing unit is located at the lifting end.

[0020] On the other hand, this application also provides a product conveying device, which includes:

[0021] Conveyor line;

[0022] In any of the above embodiments of the workpiece transfer device, the carrying part of the workpiece transfer device is disposed on one side of the conveying direction of the conveying line, and the transfer part of the workpiece transfer device drives the workpiece located at a preset position on the conveying line to slide along a preset trajectory onto the carrying part.

[0023] In one embodiment, the product conveying device further includes:

[0024] Two feeding devices are located on one side of the conveyor line in the conveying direction, and the two feeding devices are distributed at intervals along the conveyor line in the conveying direction. The two feeding devices are located upstream of the workpiece transfer device in a direction perpendicular to the conveyor line. Each feeding device is movably set relative to the conveyor line. Each feeding device has a first station close to the conveyor line and a second station far away from the conveyor line. When one feeding device is in the first station, the other feeding device is in the second station.

[0025] The material handling device includes a robotic arm, which is used to transfer workpieces from the loading device at the first station to the conveyor line.

[0026] In use, the aforementioned workpiece transfer device positions the support unit on one side of the conveyor line to ensure the workpiece can be smoothly driven from the conveyor line to the support unit. After the workpiece is conveyed to a preset position on the conveyor line, the transfer unit drives the workpiece to slide along a preset trajectory onto the support unit. This preset trajectory includes at least a first arc-shaped trajectory, with the starting point of the first trajectory at a preset position. This configuration ensures that, in the initial stage of workpiece transfer, the workpiece moves along the first arc-shaped trajectory. Compared to a method where the workpiece is driven to the support unit in a direction perpendicular to the conveyor line, the initial path and force of this transfer unit driving the workpiece from the conveyor line to the support unit are smoother, reducing impact on the workpiece. During workpiece transfer, it reduces the likelihood of deviation or tipping caused by a large difference between the force direction and the running direction when the workpiece is pushed off the conveyor line. Furthermore, during workpiece transfer, there is no need to excessively reduce the conveyor line's operating speed, improving the stability and efficiency of workpiece transfer.

[0053] See Figure 1 and Figure 2 A workpiece transfer device for transferring workpiece 01 on a conveyor line 10 includes a support part 20 and a transfer assembly. The support part 20 is disposed on one side of the conveyor line 10 in the conveying direction and is used to receive workpiece 01 from the conveyor line 10. The transfer assembly includes a transfer part 30, which is movably disposed relative to the support part 20. The transfer part 30 drives the workpiece 01 located at a preset position on the conveyor line 10 to slide along a preset trajectory onto the support part 20. The preset trajectory includes at least a first trajectory, which is arc-shaped and has a starting point at a preset position.

[0054] In use, the aforementioned workpiece transfer device places the support unit 20 on one side of the conveyor line 10 to ensure that the workpiece 01 can be smoothly driven from the conveyor line 10 onto the support unit 20. After the workpiece 01 is conveyed to a preset position on the conveyor line 10, the transfer unit 30 drives the workpiece 01 to slide along a preset trajectory onto the support unit 20. The preset trajectory includes at least a first arc-shaped trajectory, and the starting point of the first trajectory is a preset position. This arrangement ensures that in the initial stage of driving the workpiece 01 to transfer, the workpiece 01 moves along the first arc-shaped trajectory. Compared to the method where the workpiece is driven to the support unit 20 in a direction perpendicular to the conveyor line 10, the initial stage of the transfer unit 30 driving the workpiece from the conveyor line 10 to the support unit 20 in this solution has a smoother path and force, reducing the impact on the workpiece 01. During the transfer of the workpiece 01, it reduces the possibility of deviation or tipping caused by a large difference between the force direction and the running direction when the workpiece is pushed away from the conveyor line 10. During the transfer of workpiece 01, there is no need to reduce the operating speed of the conveyor line 10 excessively, which improves the stability and efficiency of the transfer of workpiece 01.

[0055] In one embodiment, the transfer unit 30 is rotatably disposed relative to the support unit 20 about a rotation axis. The end of the transfer unit 30 away from the rotation axis drives the workpiece 01 to move synchronously, so that the workpiece 01 slides to the loading position of the support unit 20, and the end point of the first trajectory is the loading position. This arrangement makes the first trajectory an arc trajectory, and the workpiece 01 slides circumferentially onto the support unit 20 about the rotation axis. The above arrangement makes the sliding process of the workpiece 01 smoother.

[0056] Furthermore, the preset trajectory also includes a second trajectory, which is arc-shaped and coaxial with the first trajectory, sharing the same radius. The starting point of the second trajectory is the loading position. The end of the transfer unit 30 away from the rotation axis drives the workpiece 01 to move synchronously, so that the workpiece 01 slides along the second trajectory to the target position of the bearing unit 20. The target position is the end point of the second trajectory. Figure 1 and Figure 2 The arrow in the image points to the rotation direction of the transfer unit 30, and... Figure 2 The dotted lines in the diagram represent the preset trajectory. This configuration allows workpiece 01, after being driven to the loading position, to continue being driven by the transfer unit 30 and move in the same manner to the target position of the carrying unit 20. Furthermore, since the first and second trajectories are coaxial and have the same radius, when workpiece 01 moves along the two arc-shaped trajectories, acceleration impacts caused by sudden trajectory changes during movement are avoided. This reduces the risk of vibration and displacement of workpiece 01 during transfer and improves the stability of workpiece 01's sliding.

[0057] In one embodiment, the end of the transfer unit 30 away from the rotation axis has a pressing structure 301. When the workpiece 01 is in a preset position, the pressing structure 301 contacts at least a portion of the workpiece 01 and pushes the workpiece 01 to slide along a first trajectory to the loading position. The pressing structure 301 effectively transmits driving force and has a simple structure. Furthermore, when the workpiece 01 is in the preset position, at least a portion of the pressing structure 301 is located behind the workpiece 01 to push the workpiece 01 to move.

[0058] It is understandable that the speed of the pressing structure 301 along the first track is greater than the speed of the conveyor line 10 conveying the workpiece 01. Thus, when the workpiece 01 is in front of the pressing structure 301 along the first track, the pressing structure 301 can contact the workpiece 01 and apply a pushing force.

[0059] When the pressing structure 301 contacts the workpiece 01, the angle between the force applied by the pressing structure 301 to the workpiece 01 and the conveying direction of the conveyor line 10 is less than 90 degrees. Furthermore, the smaller the angle between the force applied by the pressing structure 301 to the workpiece 01 and the conveying direction of the conveyor line 10, the more it helps to reduce the impact force on the workpiece 01 at the moment of contact with the pressing structure 301, and the more conducive it is to the smooth transfer of the workpiece 01.

[0060] In some embodiments, the radian of the first trajectory is less than 0.5 rad. This arrangement makes the trajectory of the pressing structure 301 when pushing the workpiece 01 along the first trajectory shorter and smoother, facilitating the pushing of the workpiece onto the support portion 20.

[0061] Furthermore, the transfer assembly also includes a rotary drive unit, which is mounted on the support unit 20 and drivenly connected to the transfer unit 30 to drive the transfer unit 30 to rotate around the rotation axis. This configuration improves the automation level of the rotation of the transfer unit 30.

[0062] In some embodiments, the pressing structure 301 includes a pressing groove with an opening on the side away from the rotation axis, and the pressing groove extends through the transfer portion 30 along the extension direction of the rotation axis. This arrangement ensures that when the pressing groove rotates along the first trajectory and the workpiece 01 is in front of the pressing groove's movement path, the pressing groove gradually contacts and covers at least a portion of the workpiece's outer peripheral surface, thereby providing limiting constraints when pushing the workpiece 01 to transfer along the first and second trajectories, reducing the possibility of the workpiece 01 shifting or swaying during the transfer process.

[0063] Furthermore, along the rotation direction of the pressing groove, a guide slope 3011 is formed on the groove wall at the front end of the pressing groove, and the distance between the guide slope 3011 and the rotation axis decreases along the direction from the front end to the rear end of the pressing groove. This allows the guide slope 3011 to smoothly guide the pressing groove to the outer periphery of the workpiece 01 when it contacts the workpiece 01, reducing the impact force on the workpiece 01 at the moment of contact and facilitating the smooth entry of the workpiece 01 into the pressing groove.

[0064] In some embodiments, the guide ramp 3011 is a first arc surface that bulges outward. This configuration further improves the smoothness of the workpiece 01 entering the pressure groove.

[0065] Preferably, at least a portion of the contour of the pressure groove is adapted to the outer contour of the workpiece 01. This configuration can improve the stability of the workpiece 01 during the transfer process.

[0066] In some embodiments, the workpiece 01 has a cylindrical structure, and the sidewall of the pressing groove includes an inwardly recessed second arc-shaped surface, with the first arc-shaped surface connected to the second arc-shaped surface. This arrangement facilitates a stable fit between the workpiece 01 and the pressing groove.

[0067] In some embodiments, the transfer unit 30 includes a turntable rotatably mounted on the support unit 20 about a rotation axis. Multiple pressure grooves are located at the periphery of the turntable and are spaced apart circumferentially along the turntable. This configuration allows for flexible adjustment of the turntable's rotation speed, the conveyor line 10's operating speed, or the workpiece 01's arrangement density on the conveyor line 10, according to actual needs, thereby improving the efficiency of workpiece 01 transfer.

[0068] In some embodiments, the workpiece transfer device further includes a limiting part 40, which is disposed on the bearing part 20 and located outside the transfer part 30. The limiting part 40 extends circumferentially along the rotation axis and cooperates with the pressing groove to prevent the workpiece 01 from disengaging from the pressing groove. This arrangement ensures that the workpiece 01 remains within the space formed by the limiting part 40 and the corresponding pressing groove during the rotation of the transfer part 30, preventing the workpiece from disengaging from the pressing groove during rotation and improving the stability of the workpiece 01 during the transfer process.

[0069] Furthermore, along the radial direction of the turntable, there is a gap between the limiting part 40 and the periphery of the turntable, and at least a portion of the workpiece 01 protrudes outward from the pressing groove and slides in contact with the inner surface of the limiting part 40. This arrangement allows the limiting part 40 to provide continuous limiting of the workpiece as it rotates with the turntable.

[0070] In some embodiments, the limiting part 40 includes a first arc segment 41 and a second arc segment 42 connected to each other. The first arc segment 41 is located above the conveyor line 10, and the second arc segment 42 is located above the support part 20. A feeding area is formed between the first arc segment 41 and the support part 20. The end of the feeding area away from the second arc segment 42 forms a feeding port for the workpiece 01 to enter the feeding area. This arrangement allows the workpiece 01 to enter the feeding area through the feeding port as it moves with the conveyor line 10. When one of the pressure grooves on the turntable rotates into the feeding area, the pressure groove gradually accommodates the workpiece. This arrangement ensures that when the pressure groove contacts the workpiece, the workpiece is in the feeding area, reducing the possibility of the workpiece 01 tipping over after being embedded in the pressure groove, and improving the stability of the workpiece at the moment of contact between the pressure groove and the workpiece.

[0071] In some embodiments, the first arc segment 41 and the second arc segment 42 are both coaxially arranged with the turntable, and the radii of the first arc segment 41 and the second arc segment 42 are the same. This arrangement ensures that the workpiece 01 maintains sliding contact with the inner wall surfaces of the first arc segment 41 and the second arc segment 42 as it rotates with the turntable, and that the force on the workpiece 01 remains uniform as it moves along the first trajectory to the second trajectory, thus improving the stability of the workpiece 01 transfer.

[0072] In some embodiments, the carrier 20 includes a mating side 201, which is in the same conveying direction as the conveyor line 10. The workpiece transfer device also includes a guide 50, which is disposed at the end of the first arc segment 41 away from the second arc segment 42. The extending direction of the guide 50 is the same as the extending direction of the mating side 201, and a feed inlet is formed between the guide 50 and the carrier 20. This arrangement allows the guide 50 to guide the workpiece 01 as it moves to the feeding area with the conveyor line 10. That is, under the combined action of the guide 50 and the mating side 201, the moving direction of the workpiece 01 is not changed when it enters the feed inlet. This arrangement can improve the accuracy and smoothness of the workpiece 01 entering the feeding area and reduce the risk of jamming or deviation of the workpiece 01 when it enters the feeding area.

[0073] Furthermore, the pressure groove contacts the workpiece 01 at the feed inlet. This arrangement can maximize the stability of the contact between the workpiece 01 and the pressure groove, and when the pressure groove contacts the workpiece 01, the workpiece 01 does not contact the first arc segment 41, that is, the movement direction of the workpiece 01 has not changed. Thus, the stability of the workpiece 01 when the pressure groove contacts the workpiece 01 can be improved.

[0074] In some embodiments, both the limiting portion 40 and the mating side 201 extend along a predetermined straight line, with the extending direction of the limiting portion 40 parallel to that of the mating side 201. This arrangement facilitates the mating side 201 to abut against the side of the straight portion of the conveyor line 10.

[0075] See Figure 1 and Figure 3 The height of the first arc segment 41 is higher than the height of the upper surface of the bearing part 20, so that the first arc segment 41 avoids the fixture 11 on the conveyor line 10 where the workpiece 01 is placed. Under certain working conditions, the workpiece 01 is placed on the fixture 11 of the conveyor line 10. After the workpiece 01 is transferred to the bearing part 20 by the transfer part 30, the fixture 11 separates from the workpiece 01. The fixture 11 continues to move with the conveyor line 10. The setting of the first arc segment 41 ensures that the fixture 11 is located below the first arc segment 41 during the process of continuing to move with the conveyor line 10, avoiding interference between the fixture 11 and the first arc segment 41, and improving the smoothness of the conveyor line 10.

[0076] In some embodiments, both the first arc segment 41 and the guide portion 50 are strip-shaped structures, and are integrally formed, with the first arc segment 41 and the guide portion 50 having the same height. This arrangement enhances the structural strength between the first arc segment 41 and the guide portion 50, facilitates contact between the first arc segment 41 and the guide portion 50 and the workpiece 01 at the same height, and improves the smoothness of the workpiece transfer from the guide portion 50 to the first arc segment 41.

[0077] In some embodiments, the second arc segment 42 is an arc plate-shaped structure. This configuration makes the second arc segment 42 more effective in guiding the workpiece 01 as it moves along the second trajectory with the pressure groove, reducing the risk of the workpiece 01 shaking or deviating during the transfer process.

[0078] See Figure 1 and Figure 2 The support unit 20 is provided with a discharge port 202, which is the end point of a preset trajectory. When the transfer unit 30 drives the workpiece 01 to slide to the discharge port 202, the workpiece 01 is removed from the support unit 20 through the discharge port 202. This configuration allows the workpiece 01 to fall into the next station through the discharge port 202 after being transferred to the support unit 20. This configuration eliminates the need for additional structures to transfer the workpiece 01 on the support unit 20, thus improving the transfer efficiency of the workpiece 01.

[0079] It is understandable that the end point of the second trajectory is the end point of the preset trajectory. After the end of the transfer unit 30 away from the rotation axis drives the workpiece 01 to the unloading port 202 position, the transfer unit 30 continues to rotate. The end of the transfer unit 30 away from the rotation axis approaches other workpieces located at preset positions on the conveyor line 10 again, thereby realizing continuous workpiece transfer operation.

[0080] In some embodiments, the workpiece transfer device further includes a storage section 90 located below the support section 20. The top of the storage section 90 is open, and the opening of the storage section 90 corresponds to the discharge port 202. In this way, after the workpiece 01 leaves the support section 20 through the discharge port 202, it can fall directly into the storage section 90, thereby temporarily storing the workpiece 01 and improving the continuity of the transfer of the workpiece 01.

[0081] In some embodiments, the workpiece transfer device further includes a lifting unit 60, which has a lifting end that is vertically movable, and a carrying unit 20 is disposed at the lifting end. This arrangement allows the device, when used in conjunction with the conveyor line 10, to align the carrying unit 20 with the fixture 11 of the conveyor line 10 when a specific workpiece 01 needs to be transferred. The transfer unit 30 then transfers the workpiece 01 from the fixture 11 to the carrying unit 20. Subsequently, the lifting unit 60 drives the carrying unit 20 to rise or fall, while other workpieces 01 on the conveyor line 10 continue to move along the conveyor line. This enables precise transfer of specific workpieces without affecting the normal transport of other workpieces 01, improving the flexibility and automation of the production line operation.

[0082] In some embodiments, the workpiece transfer device further includes a buffer section disposed below the support section 20. The bottom end of the buffer section is connected to the mounting base, and the top end is connected to the support section 20. This improves the stability of the support section 20 during lifting and lowering.

[0083] See Figure 2 , Figures 4 to 7 This application provides a product conveying device, which includes a workbench 100, a conveyor line 10, and a workpiece transfer device according to any of the above embodiments. The conveyor line 10 and the workpiece transfer device are both arranged on the workbench 100. The carrying part 20 of the workpiece transfer device is located on one side of the conveying direction of the conveyor line 10. The transfer part 30 of the workpiece transfer device drives the workpiece 01 located at a preset position on the conveyor line to slide along a preset trajectory onto the carrying part 20.

[0084] In some embodiments, the conveyor line 10 is a circular magnetic drive conveyor line. The magnetic drive conveyor line includes two straight conveyor sections and two arc-shaped conveyor sections. The two straight conveyor sections are parallel and spaced apart, and the two arc-shaped conveyor sections are located at opposite ends of the two straight conveyor sections. Each arc-shaped conveyor section is connected to one of the two adjacent ends of the two straight conveyor sections. The support portion 20 is located outside the straight conveyor sections. Multiple fixtures 11 are spaced apart on the magnetic drive conveyor line 10, and each fixture 11 holds a workpiece 01.

[0085] In some embodiments, the fixture 11 includes an interconnected base and side plates. The base is used to place the workpiece 01, and the side plates are disposed above the base. The side plates have slots that fit a portion of the circumferential outer contour of the workpiece 01. The product conveyor line also includes a guardrail 12, which is disposed on the workbench 100 and located on the outer periphery of the conveyor line 10. The guardrail 12 is positioned opposite the side plates, and the slots on the guardrail 12 and side plates restrict the position of the workpiece on the fixture 11. The guardrail 12 is interrupted at the location of the workpiece transfer device. When the fixture 11 moves to the location of the workpiece transfer device, the opening of the slot faces the workpiece transfer device, so that the pressing structure 301 of the transfer section 30 drives the workpiece 01 from the fixture 11 to the carrier section 20. The arrangement of the guardrail 12 and the fixture 11 improves the stability of the workpiece 01 during the conveying process.

[0086] In some embodiments, the product conveying equipment further includes two feeding devices 70 and a picking device 80. The two feeding devices 70 are both arranged on the workbench 100 and are located on one side of the conveying direction of the conveyor line 10. The two feeding devices 70 are distributed at intervals along the conveying direction of the conveyor line 10. The two feeding devices 70 are located upstream of the workpiece transfer device and in a direction perpendicular to the conveyor line 10. Each feeding device 70 is movably arranged relative to the conveyor line 10. Each feeding device 70 has a first station close to the conveyor line 10 and a second station away from the conveyor line 10. When one feeding device 70 is in the first station, the other feeding device 70 is in the second station. The picking device 80 includes a robot arm 801, which is used to transfer the workpiece 01 on the feeding device 70 in the first station to the conveyor line 10. This configuration allows the two feeding devices 70 to feed in an alternating manner. When the robot arm 801 grabs the workpiece 01 on the feeding device 70 at the first station, the other feeding device 70 can move to the second station to replenish the workpiece 01. After the robot arm 801 completes the current feeding, the feeding device 70 moves back to the first station to prepare for the next feeding. This cycle achieves continuous and uninterrupted feeding, improving feeding efficiency.

[0087] See Figure 8 The product conveying equipment also includes a guide rail 71 mounted on the workbench 100. The guide rail 71 extends in a direction perpendicular to the conveyor line 10. The guide rail 71 corresponds to and cooperates with the feeding device 70, which is slidably mounted on the guide rail 71. This arrangement can improve the stability of the movement of the feeding device 70.

[0088] Furthermore, the product conveying device also includes two positioning parts 72 disposed on the workbench 100, each corresponding to one of the two feeding devices 70. The positioning part 72 is located in front of the corresponding feeding device 70 at the first working position, and is used to abut against the feeding device 70 when it moves to the first working position. Each positioning part 72 may include a guide pin, and the feeding device 70 has a pin hole. When the feeding device 70 moves to the first working position, the positioning pin inserts into the pin hole to achieve positioning; when the feeding device 70 needs to move to the second working position, the positioning pin retracts from the pin hole. The positioning pin and pin hole configuration is simple in structure and provides strong positioning stability.

[0089] In some embodiments, the positioning part 72 further includes a spherical positioning member with its spherical surface facing the positioning part 72. The feeding device 70 is correspondingly provided with an abutment groove that mates with the spherical surface. When the feeding device 70 moves to the first station, the spherical surface of the spherical positioning member is embedded in the abutment groove. The spherical positioning member, based on the coarse positioning of the positioning pin and pin hole, further improves the positioning accuracy of the feeding device 70, ensuring the consistency of the workpiece 01 at the first station and reducing the gripping error of the robot arm 801.

[0090] In some embodiments, the product conveying device further includes a proximity switch and a magnetic suction unit connected by communication. Each first station is equipped with a proximity switch and a magnetic suction unit. The proximity switch senses the position of the corresponding feeding device 70. When the proximity switch detects that the corresponding feeding device 70 has moved to the first station, the proximity switch transmits the sensed signal to the magnetic suction unit through the control system. The magnetic suction unit then magnetically attaches to the feeding device 70 for positioning. This arrangement improves the stability of the feeding device 70 at the first station and enhances the accuracy and reliability of the robot arm 801 in grasping the workpiece 01.

[0091] See Figure 6 and Figure 7 The product conveying device also includes a first slide rail 81, a second slide rail 82, and a third slide rail 83 located above the conveyor line 10 and the feeding device 70. The first slide rail 81 extends horizontally along the straight conveying section of the conveyor line 10; the second slide rail 82 extends horizontally and perpendicular to the first slide rail 81, and slides in cooperation with the first slide rail 81 along its extension direction; the third slide rail 83 extends vertically and slides in cooperation with the second slide rail 82 along its extension direction. The robot arm 801 slides in cooperation with the third slide rail 83 vertically. This configuration improves the movement accuracy of the robot arm 801 in three-dimensional space and enhances the smoothness and stability of the robot arm 801 in grasping the workpiece 01.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

[0093] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
