Description

Technical Field

[0001] This utility model relates to the field of workpiece conveying technology, and in particular to a shuttle transfer device and production line. Background Technology

[0002] During the production process, sheet metal workpieces need to undergo multiple processing stations, including stamping and shearing, to achieve the required structural shape. Therefore, it's necessary to transfer the workpieces between these stations. The conventional method is to use a robotic arm to pick up the workpiece and move it to the next station. This transfer can involve the robotic arm itself moving, or it can pick up the workpiece and place it on a conveyor belt, which then transports it to the next station. However, using a robotic arm for picking up and transferring the workpiece is unsuitable for transferring between stations with varying widths due to its limited range of motion. If a conveyor belt is used, precise control of the conveyor speed is required, placing high demands on control systems.

[0003] Chinese patent CN201810115178.9 discloses a high-efficiency robotic automated stamping line, including a loading trolley, a first stamping machine, a shuttle device, a second stamping machine, a picking station, a loading robot, and a unloading robot. The loading trolley comprises a base plate, a feeding plate, a support frame, and wheels. A base block with a bearing seat is mounted on the base plate. The feeding plate is mounted on the base plate, and the support frame is mounted on the feeding plate. This invention incorporates magnetic plates connected to the support frame of the loading trolley via bolts. This allows for magnetic separation of the stamped parts stacked on the feeding plate, creating a gap between adjacent pieces to be stamped. This facilitates the unloading of the stacked parts, improving stamping efficiency. The loading and unloading robots are positioned on opposite sides of the first and second stamping machines, respectively, further improving both the loading and unloading efficiency and the overall efficiency of the stamping machines. However, this design requires further improvement.

[0004] This invention overcomes the shortcomings of the prior art and provides a shuttle transfer device and production line, which has the advantages of long conveying and transfer distance and simple control. Utility Model Content

[0033] like Figure 1-4 The diagram shown is a schematic representation of an embodiment of the shuttle movement device provided by this utility model.

[0034] Please refer to Figure 1-4 This embodiment is used for transferring and conveying workpieces between adjacent workstations. The embodiment includes a base 11, which has several slide rail units 12. The slide rail units 12 are connected by a scissor structure 13. Multiple slide rail units 12 are arranged in a horizontally parallel stack, with adjacent slide rail units 12 slidably connected. The length of the slide rail intervals of the multiple slide rail units 12 decreases sequentially from bottom to top. The uppermost slide rail unit 12 is provided with a support platform 14, which is slidably connected to the uppermost slide rail unit 12. The first end of the scissor structure 13 is hinged to the base 11, and the second end of the scissor structure 13 is hinged to the support platform 14. The scissor structure 13 moves telescopically via a power component 15. The telescopic movement of the scissor structure 13 causes the slide rail units 12 to slide relative to each other, and causes the support platform 14 to move linearly in the horizontal direction.

[0035] The power component 15 drives the scissor lift structure 13 to extend and retract, thereby moving multiple slide rail units 12 in a straight line, thus achieving linear movement of the support platform 14. The slide rail units 12 are stacked, and the scissor lift structure causes them to stagger at both ends. The lengths of the slide rail units 12 overlap, extending the conveying distance and enabling long-distance movement of the support platform 14 for long-distance workpiece transport. By designing the connection points between the slide rail units 12 and the scissor lift structure 13, as well as the sliding positions between the slide rail units 12, it is possible to ensure that the slide rail units 12 partially overlap during movement, maintaining a certain load-bearing strength. Since the length of the slide rail units 12 decreases sequentially from bottom to top, a sloping structure can also be formed. This sloping design increases the moving range while requiring less space below, making it suitable for installation requirements of different production lines.

[0036] In one embodiment, the telescopic length of the scissor lift structure 13 is in a predetermined proportion to the horizontal movement length of the slide rail unit 12, and the telescopic length of the scissor lift structure 13 is in a predetermined proportion to the horizontal movement length of the support platform 14. By simultaneously rotating around the hinge point with the base 11 during the telescopic process of the scissor lift structure 13, the motion of this movement process is proportional to the horizontal movement process of the slide rail unit 12, so as to prevent jamming during the movement process of the slide rail unit 12 and the telescopic process of the scissor lift structure 13.

[0037] In one embodiment, the slide rail units 12 are connected by a first slide table 121. The lower side of the first slide table 121 is slidably connected to the slide rail unit 12 below it, and the upper side of the first slide table 121 is fixedly connected to the middle of the slide rail unit 12 above it. The support platform 14 is connected by a second slide table 122. The lower side of the second slide table 122 is slidably connected to the slide rail unit 12, and the upper side of the second slide table 122 is fixedly connected to the support platform 14. The support platform 14 is used to support the workpiece. This design enables the slide rail units 12 to extend the conveying range, while limiting the overlap between adjacent slide rail units 12 to always half, reducing the load on each slide rail unit 12 when the support platform 14 is located at the end of the range.

[0038] Specifically, in this embodiment, there are three slide rail units 12. The bottom slide rail unit 12 is the longest and is fixedly connected to the base 11. Adjacent slide rail units 12 are slidably connected to each other through the first slide table 121. The top slide rail unit 12 is slidably connected to the support platform 14 through the second slide table 122.

[0039] Furthermore, the first end of the scissor lift structure 13 is connected to the middle of the base 11, and the lowermost slide rail unit 12 is fixedly connected to the base 11. The scissor lift structure 13 is located on the side of the slide rail unit 12. During the movement of the support platform 14 from the leftmost to the rightmost position of the base 11, the scissor lift structure 13 retracts and rotates clockwise around the hinge point with the base 11. After the support platform 14 passes this hinge point, the scissor lift structure 13 extends. During the movement of the support platform 14 from the rightmost to the leftmost position of the base 11, the scissor lift structure 13 retracts and rotates counterclockwise around the hinge point with the base 11. After the support platform 14 passes this hinge point, the scissor lift structure 13 extends. The above describes the specific process of the support platform 14 moving from the left to the right and from the right to the left, demonstrating bidirectional movement capability.

[0040] In one embodiment, the system further includes a lifting assembly 16 and a frame 17. The frame 17 is disposed on a horizontal plane and fixedly connected to the horizontal plane. The lifting assembly 16 is disposed on the frame 17, and the base 11 is connected to the frame 17 through the lifting assembly 16. The lifting assembly 16 drives the base 11 to rise and fall. The lifting assembly 16 is used to realize the lifting and falling of the base 11 and the slide rail unit 12 and scissor structure 13 connected to the base 11, so as to adapt to the workpiece transfer with different workstation height requirements.

[0041] Specifically, the lifting assembly 16 includes a lifting cylinder 161 and a guide column 162, which are mounted on the frame 17. The telescopic ends of the lifting cylinder 161 and the guide column 162 are respectively connected to the base 11. The guide columns 162 are symmetrically arranged on both sides of the lifting cylinder 161 for guiding and supporting. The telescopic ends of the lifting cylinder 161 are connected to the lower center of the base 11.

[0042] In one embodiment, the scissor lift structure 13 includes a first link 131, a second link 132, and a third link 133. Two second links 132 form a group, and the two second links 132 in a group are cross-connected and hinged at the intersection. The intersection is hinged to the slide rail unit 121 or the power assembly 15, specifically through a connecting post 19. Multiple groups of second links 132 are sequentially arranged to form a front connecting end and a rear connecting end. The base 11 is hinged to the first ends of the two first links 131 at a single point, the tail ends of the first links 131 are hinged to the front connecting end, the tail ends of the two third links 133 are hinged to the support platform 14 at a single point, and the first ends of the third links 133 are hinged to the rear connecting end. The first link 131, the second link 132, and the third link 133 form multiple rhomboid structures as shown in the figure. There are multiple groups of second links 132. The lengths of the two second links 132 in each group can be equal or unequal. The arrangement ensures that the rhombus formed by the connection of the first link 131, the second link 132, and the third link 133 is a parallelogram structure, so as to achieve stable contraction and elongation.

[0043] In one embodiment, the power assembly 15 includes a motor 151, a lead screw 152, and a bushing 153. The motor 151 is mounted on the base 11, and the lead screw 152 is located below the slide rail unit 12, parallel to it. The motor 151 and lead screw 152 are connected by a drive mechanism. The bushing 153 is threadedly connected to the lead screw 152, and the intersection point of the bushing 153 and the second connecting rod 132 is hinged via a connecting post 19. The lead screw 152 uses a conventional drive mechanism; its specific principle and structure will not be detailed here. The hinge point between the second connecting rod 132 and the bushing 153 is the power output point, and the hinge point between the second connecting rod 132 and the slide rail unit 12 is the transmission point, thus realizing the transmission between the second connecting rod 132 and the slide rail unit 12.

[0044] In one embodiment, the system further includes a lifting platform 18 and a lifting cylinder 161. The lifting platform 18 is located at the left or right end of the moving section of the support platform 14. The lifting cylinder 161 drives the lifting platform 18 to be higher or lower than the horizontal plane of the support platform 14. The lifting platform 18 is used for workpiece transfer. The lifting platform 18 lifts the workpiece in the workstation above the plane of the support platform 14. The support platform 14 moves to directly below the lifting platform 18 via the slide rail unit 12 and the scissor structure 13. Then, the lifting platform 18 lowers the workpiece until the support platform 14 contacts the workpiece, thereby transferring the workpiece from the lifting platform 18 to the support platform 14.

[0045] like Figure 5 The diagram shown is a schematic representation of a production line embodiment provided by this utility model.

[0046] Please refer to Figure 5 This embodiment includes the shuttle transfer device 10 described above and the work station 20. The shuttle transfer component 10 is disposed between the work stations 20 and is used for the transfer of workpieces between the work stations 20.

[0047] In summary, the shuttle transfer device embodiment provided by this utility model uses a power component to drive the scissor structure to extend and retract, thereby driving multiple slide rail units to move in a straight line. The slide rail units are stacked together, and the scissor structure drives the slide rail units to stagger at both ends. The lengths of the slide rail units are superimposed to each other, thereby achieving an extended range of conveying distance, and thus enabling long-distance movement of the carrying platform. Therefore, long-distance conveying of workpieces can be achieved.
