Description

Technical Field

[0001] This invention relates to the field of automated production equipment technology, specifically a shuttle machine suitable for multi-station production lines. Background Technology

[0002] Shuttles, as a type of transport equipment, are mainly used for the transfer and conveying of materials between different workstations. They are key equipment for improving automation levels, production efficiency, product quality, and safety. For example, in a multi-station stamping production line for automobiles, the shuttle is the core hub equipment for achieving efficient, precise, and automated transfer of large sheet metal parts. It perfectly solves the problem of high-speed, stable, and damage-free handling of sheet metal between multiple press stations.

[0003] Positioning materials is a crucial step during workstation transitions; however, existing shuttles often only offer unidirectional transport. To ensure accurate positioning, existing shuttles typically require a separate positioning device to pinpoint the delivered materials.

[0004] Furthermore, the conveying parameters required by shuttles differ between different pieces of equipment. Taking a multi-station stamping production line as an example, the mold heights at different press stations vary, and the distances between different press stations may also differ due to site layout limitations. However, existing shuttles are often fixed structures, unable to adjust conveying parameters (conveying distance, height), and lack versatility. Therefore, in actual production, different specifications of shuttles need to be configured according to specific requirements. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a shuttle machine suitable for multi-station production lines that not only has positioning capabilities but also excellent versatility.

[0016] Furthermore, the first bracket is equipped with a dual-material detection switch and a material presence detection switch.

[0017] Furthermore, the striking component includes a first striking rod, a second striking rod, a striking cylinder, and a mounting plate. The mounting plate is provided with a first linear module, a second linear module, and a third linear module arranged in parallel.

[0018] Furthermore, a second bracket is provided on the mounting plate inside the striking block.

[0019] Furthermore, the striking component is slidably connected to the second carriage, and the two striking components can move towards each other or away from each other under the driving action of the fourth driving component.

[0045] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0046] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0047] like Figure 1 As shown, a shuttle machine suitable for multi-station production lines includes a base lifting assembly 1, a slide assembly 2, and a centering and tapping assembly 3.

[0048] The base lifting assembly 1 has a lifting function. Driven by the base lifting assembly 1, the slide assembly 2 and the centering tapping assembly 3 can move up and down as a whole to adjust the height.

[0049] like Figure 4 , Figure 5 and Figure 6 As shown, the base lifting assembly 1 includes a base frame 11 and a first driving component for driving the base frame 11 to move up and down.

[0050] In one specific implementation, the base frame 11 in this embodiment includes a first frame 111 formed by four first side beams connected end to end in sequence. Each of the four corners of the first frame 111 is provided with a leg 112 extending downward perpendicular to the first frame 111, and a first connecting beam 113 is provided between two adjacent legs 112.

[0051] The first driving component includes a screw jack 121 and a first motor 122. The housing of the screw jack 121 is detachably fixedly connected to the base frame 11. The push end of the screw of the screw jack 121 faces downward and is detachably fixedly connected to the base plate 4 fixedly installed on the ground. The power output end of the first motor 122 is connected to the power input end of the screw jack 121 via a drive shaft.

[0052] In one specific implementation, four screw jacks 121 are provided on the base frame 11 in this embodiment. The four screw jacks 121 are grouped in pairs and located on both sides of the base frame 11. Figure 1In the coordinate system shown, two screw jacks 121 are respectively installed on the front and rear sides of the base frame 11, and the four screw jacks 121 are arranged in a matrix of two rows and two columns. Each of the four legs 112 of the base frame 11 is provided with a first mounting base 114, and a screw jack 121 is fixedly mounted on each first mounting base 114.

Second mounting bases 115 are respectively installed on the first connecting beams 113 located on the left and right sides, and commutators 123 are installed on the second mounting bases 115. The two output ends of the commutator 123 located on the right side are connected to the power input ends of the two screw jacks 121 located on the right side via a first drive shaft 124; the two output ends of the commutator 123 located on the left side are connected to the power input ends of the two screw jacks 121 located on the left side via a second drive shaft 125. A first motor mount 116 is disposed on the base frame 11 between the two commutators 123, and the first motor 122 is detachably fixed to the first motor mount 116. A third drive shaft 126 is disposed at the power output end of the first motor 122, and both ends of the third drive shaft 126 are connected to the input ends of the two commutators 123, respectively. For example, the reducer of the first motor 122 adopts a hollow shaft structure, that is, the third drive shaft 126 passes laterally through the reducer of the first motor 122, and the first motor mount 116 is disposed on the first connecting beam 113 located on the right side.

[0053] Furthermore, a guide assembly is provided on the base frame 11, which is used to guide the vertical movement of the base frame 11.

[0054] The guide assembly includes a guide rod 131 and a guide seat 132 that cooperates with the guide rod 131. The guide seat 132 is detachably fixed to the base frame 11. The lower end of the guide rod 131 is detachably fixed to the foot plate 4 fixed on the ground.

[0055] In one specific implementation, the base frame 11 described in this embodiment is provided with four guide components, and the four guide components are respectively located at the four corners of the base frame 11.

[0056] In one specific embodiment, the support legs 112 of the base frame 11 are made of steel pipes. A base plate 1121 is fixedly mounted on the lower end of the support leg 112 by welding. The base plate 1121 has mounting holes. The guide seat 132 uses a linear bearing. The upper end of the linear bearing passes through the mounting holes and is inserted into the support leg 112. The flange of the linear bearing is located below the base plate 1121 and is fixedly connected to the base plate 1121 by screws. An end plate 1311 is fixedly mounted on the lower end of the guide rod 131. The end plate 1311 is fixedly connected to the foot plate 4 fixed to the ground by screws. The upper end of the guide rod 131 extends through the guide seat 132 into the interior of the support leg 112 and forms a guiding engagement with the guide seat 132. A baffle 1312 is provided on the guide rod 131 above the guide seat 132, and the baffle 1312 is fixedly connected to the guide rod 131 in a detachable manner. For example, the baffle 1312 is fixed to the upper end face of the guide rod 131 by screws.

[0057] Here, guide components may or may not be provided. Furthermore, the number and installation position of the guide components and the screw jack 121 are not limited to this embodiment, but can be adapted to meet specific needs, as long as the base frame 11 is stable.

[0058] like Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the slide assembly 2 includes a first slide 21, which is slidably connected to the base frame 11 via a first sliding component. A second driving component is provided between the first slide 21 and the base frame 11 of the base lifting assembly 1 for driving the first slide 21 to slide back and forth relative to the base frame 11.

[0059] In one specific implementation, the first carriage 21 in this embodiment includes a second frame 211 formed by four second side beams connected end to end in sequence. A second connecting beam 212 is provided within the second frame 211, and the second connecting beam 212 is parallel to the sliding direction of the first carriage 21. Figure 1 As shown in the coordinates, the second connecting beam 212 extends laterally. A plurality of third connecting beams 213 are provided between the second connecting beam 212 and a second side beam on one side. For example, according to... Figure 1 In the coordinate system shown, two third connecting beams 213 are provided between the second connecting beam 212 and the second side beam located on the front side.

[0060] In one specific implementation, the first sliding assembly described in this embodiment adopts a linear guide rail pair. The first sliding assembly includes first guide rails 22 disposed at the front and rear ends of the lower side of the first slide 21. For example, the two first guide rails 22 are respectively fixedly connected to the second side beams on the front and rear sides of the first slide 21 by bolts. The front and rear ends of the upper side of the base frame 11 are respectively provided with a plurality of first sliders 14 that cooperate with the first guide rails 22. For example, the first side beams on the front and rear sides of the base frame 11 are respectively provided with three first sliders 14 that cooperate with the first guide rails 22.

[0061] The second driving component includes a second motor 15 mounted on the base frame 11, a gear 151 mounted on the power output end of the second motor 15, and a rack 23 mounted on the first slide 21 that meshes with the gear 151.

[0062] In one specific embodiment, the rack 23 is fixedly mounted on the side of the second connecting beam 212 facing away from the third connecting beam 213 by screws. A second motor mount 117 is provided on the base frame 11 within the first frame 111 of the base frame 11, and the second motor 15 is detachably fixed to the second motor mount 117. For example, the second motor mount 117 is fixedly mounted to the first side beam on the left side of the first frame 111 by welding.

[0063] like Figure 9 As shown, the centering and tapping device includes a second slide 31, which is slidably connected to the first slide 21 via a second sliding component. The sliding direction of the second slide 31 is parallel to the sliding direction of the first slide 21, and a third driving component is provided between the first slide 21 and the second slide 31 to drive the second slide 31 to reciprocate relative to the first slide 21. Figure 1 In the coordinate system shown, both the first slide 21 and the second slide 31 slide in the left-right direction.

[0064] The second slide 31 has a first bracket 32 ​​in the middle. The second slide 31 has striking components 33 on both sides of the first bracket 32. The two striking components 33 have identical structures and are symmetrically arranged about a first symmetrical plane extending vertically. This first symmetrical plane is parallel to the sliding direction of the second slide 31. Figure 1 In the coordinate system, the two striking components 33 are located at the front and rear ends of the second slide 31, respectively.

[0065] Preferably, the first bracket 32 ​​is symmetrical about a second symmetrical plane extending in the vertical direction, and the first symmetrical plane coincides with the second symmetrical plane. That is, the two striking components 33 are arranged symmetrically about the first bracket 32.

[0066] As one specific implementation method, such as Figure 11 As shown, the second carriage 31 in this embodiment includes a third frame 311 formed by four third side beams connected end to end in sequence. For example, according to... Figure 1 In the coordinate system shown, the two longitudinally extending third side beams are located above the two transversely extending third side beams. The lower side of the longitudinally extending third side beam is fixedly connected to the upper side of the transversely extending third side beam by welding. Stiffeners are provided between the longitudinally extending and transversely extending third side beams. Below the third frame 311, two transversely extending fourth connecting beams 312 are provided. The two fourth connecting beams 312 are located in the middle of the third frame 311, and their two ends are fixedly connected to the two longitudinally extending third side beams by welding.

[0067] As one specific implementation method, such as Figure 7 , Figure 8 , Figure 11 and Figure 13 As shown, the second sliding assembly in this embodiment adopts a linear guide rail pair. The second sliding assembly includes second guide rails 24 disposed at the front and rear ends of the upper side of the first slide 21. Exemplarily, the two second guide rails 24 are respectively fixedly connected to the second side beams on the front and rear sides of the first slide 21 by bolts. A second slider 34 that cooperates with the second guide rails 24 is disposed on the lower side of the second slide 31. Exemplarily, third mounting seats 313 extending inward (with the opposite side of the two longitudinally extending third side beams as the inner side) are respectively disposed on the third side beams on both sides of the first bracket 32. The second slider 34 is fixedly disposed on the lower side of the third mounting seat 313 by screws.

[0068] like Figure 3 , Figure 7 and Figure 8As shown, the third driving component includes a driving pulley 251 and a driven pulley 252 mounted on the first carriage 21. A synchronous belt 253 is provided between the driving pulley 251 and the driven pulley 252. The driving pulley 251 is directly or through a first transmission mechanism connected to the power output end of the third motor 26. The third motor 26 is detachably fixed to the first carriage 21. The second carriage 31 is connected and fixed to the synchronous belt 253 through a connecting assembly 35. When the synchronous belt 253 moves under the drive of the third motor 26, it can drive the second carriage 31 to reciprocate along with the synchronous belt 253 through the connecting assembly 35.

[0069] As one specific implementation method, according to Figure 1 In the coordinate system shown, in this embodiment, the driving pulley 251 is mounted on the second side beam on the right side of the first slide 21 via a fourth mounting base 214, and the driven pulley 252 is mounted on the second side beam on the left side of the first slide 21 via a fifth mounting base 215. The third motor 26 is mounted on the second side beam on the right side of the first slide 21 via a third motor mount 216, and the power output end of the third motor 26 is connected to the axle of the driving pulley 251 via a coupling (i.e., a direct connection). The connecting assembly 35 includes a first clamping plate 351 and a second clamping plate 352. The first clamping plate 351 is fixedly mounted on the underside of the third side beam on the right side of the second slide 31 by welding, and the second clamping plate 352 is located below the first clamping plate 351 and is connected to the first clamping plate 351 by locking bolts. The timing belt 253 is located between the first clamping plate 351 and the second clamping plate 352, and under the locking action of the locking bolt, the timing belt 253 is clamped and fixed between the first clamping plate 351 and the second clamping plate 352.

[0070] As one specific implementation method, such as Figure 9 and Figure 11 As shown, the first bracket 32 ​​in this embodiment includes a connecting plate 321, both ends of which are fixedly connected to two fourth connecting beams 312. A vertical beam 322 extending upwards perpendicular to the connecting plate 321 is provided on the connecting plate 321. A support beam 323 is fixedly provided at the upper end of the vertical beam 322 by welding, and the support beam 323 slides in the same direction as the second slide 31. Ribs are respectively provided on both sides of the vertical beam 322 between the support beam 323 and the vertical beam 322. A first support plate 324 is provided on the support beam 323, and the first support plate 324 is fixedly connected to the support beam 323 in a detachable manner.

[0071] Furthermore, the first bracket 32 ​​is provided with a material detection switch 325 for detecting whether there is material.

[0072] As one specific implementation method, such as Figure 14 As shown, the material detection switch 325 in this embodiment is a conventional photoelectric switch, and the material detection switch 325 is mounted on one side of the support beam 323 via the first switch bracket 3251.

[0073] Furthermore, a dual-material detection switch 326 is provided on the first bracket 32. The dual-material detection switch 326 is used to detect the number of sheets placed on the first bracket 32 ​​to avoid the situation of two or more sheets.

[0074] Due to factors such as the oil film on the surface of the sheet metal, steel sheets often stick together, easily resulting in double or multiple layers of sheet metal during loading. If double or multiple layers of sheet metal are fed into the press, not only may defective products be produced, but serious damage to the equipment or molds can also occur, leading to high repair costs and delays in normal production. To ensure the safety of the equipment and molds and guarantee continuous production, this embodiment of the application provides a double-sheet detection switch 326 on the first bracket 32 ​​to prevent this from happening. The double-sheet detection switch 326 is prior art, and its specific structure will not be described in detail here.

[0075] In one specific embodiment, a second switch bracket 3261 is provided on the lower side of the first tray 324, and the second switch bracket 3261 is detachably fixedly connected to the first tray 324. The dual-material detection switch 326 is detachably fixedly mounted on the second switch bracket 3261. The first tray 324 is provided with a clearance hole for avoiding the dual-material detection switch 326, and the dual-material detection switch 326 can perform dual-material detection on the sheet material placed on the first tray 32 through the clearance hole.

[0076] like Figure 15 and Figure 16 As shown, the striking component 33 includes a first striking rod 331, a second striking rod 332, a striking cylinder 333, and a mounting plate 334.

[0077] The mounting plate 334 is provided with a first linear module 335, a second linear module 336, and a third linear module 337. One end of the first linear module 335 is provided with a first module motor 3353 for driving the first linear module 335; one end of the second linear module 336 is provided with a second module motor 3363 for driving the second linear module 336; and one end of the third linear module 337 is provided with a third module motor 3373 for driving the third linear module 337.

[0078] The first striking rod 331 is connected to the slide of the first linear module 335, and the second striking rod 332 is connected to the slide of the second linear module 336. The first striking rod 331 and the second striking rod 332 can move towards each other or away from each other under the drive of the first linear module 335 and the second linear module 336, thereby striking the sheet metal in a first direction, and the first direction is parallel to the sliding direction of the second slide 31. Figure 1 In the coordinate system shown, the first striking rod 331 and the second striking rod 332 are located on the left and right sides of the first slide 21, respectively. When the first striking rod 331 and the second striking rod 332 move towards each other under the drive of the first linear module 335 and the second linear module 336, they can perform lateral striking on the sheet material.

[0079] The striking cylinder 333 is mounted on a slide table of the third linear module 337. The piston rod of the striking cylinder 333 faces the first bracket 32, and a striking block 3331 is provided at the end of the piston rod. The striking cylinder 333 can reciprocate along a first direction under the drive of the third linear module 337. The extension and retraction direction of the piston rod of the striking cylinder 333 is a second direction, and the second direction is perpendicular to the first direction, that is, the striking cylinder 333 performs longitudinal striking on the sheet metal.

As a specific embodiment, in this example, the first linear module 335, the second linear module 336, and the third linear module 337 all use synchronous belt linear modules 253.

A detachable first adapter plate 3352 is fixedly provided on the slide of the first linear module 335. The first striking rod 331 is located on the inner side of the mounting plate 334 (with the side opposite to the two striking components 33 as the inner side), and the lower end of the first striking rod 331 is fixedly connected to the first adapter plate 3352 in a detachable manner. A second linear module 336 is provided at the right end of the lower side of the mounting plate 334, and the second linear module 336 is fixedly connected to the mounting plate 334 via a second connecting block 3361.

The second striking rod 332 is located inside the mounting plate 334 (with the side opposite to the two striking components 33 as the inner side), and the lower end of the second striking rod 332 is detachably fixedly connected to the second adapter plate 3362. The first linear module 335 is located inside the second linear module 336 (with the side opposite to the two striking components 33 as the inner side), and the opposite ends of the first linear module 335 and the second linear module 336 partially overlap, that is, the right end face of the first linear module 335 is located to the right of the left end face of the second linear module 336. The third linear module 337 is located on the upper side of the mounting plate 334 and is connected and fixed to the mounting plate 334 through a third connecting block 3371. The slide of the third linear module 337 is provided with a detachable third adapter plate 3372, and the cylinder body of the striking cylinder 333 is detachably connected and fixed to the third adapter plate 3372.

[0082] Furthermore, a second bracket is provided on the mounting plate 334 on the inner side of the striking block 3331 (with the side opposite to the two striking components 33 as the inner side). The second bracket includes a second support plate 3381 and a support plate bracket 3382 for supporting the second support plate 3381. The upper end of the support plate bracket 3382 is fixedly connected to the second support plate 3381 by screws, and the lower end of the support plate bracket 3382 is fixedly connected to the mounting plate 334 by screws. For example, three support plate brackets 3382 are provided on the second support plate 3381 along the length direction of the second support plate 3381.

[0083] Preferably, the first striking bar 331 and the second striking bar 332 are located inside the second bracket (with the side opposite to the two striking components 33 as the inside).

[0084] Furthermore, such as Figure 10 , Figure 11 and Figure 15 As shown, the mounting plate 334 of the striking component 33 is slidably connected to the second slide 31 via a third sliding assembly. The centering striking assembly 3 also includes a fourth driving component, under the driving action of the fourth driving component, the two striking components 33 can move towards each other or away from each other.

[0085] In one specific implementation, the third sliding component in this embodiment adopts a linear guide rail pair. The third sliding component includes third guide rails 361 disposed at the left and right ends of the upper side of the second slide 31. For example, the two third guide rails 361 are fixedly connected to two longitudinally extending third side beams of the second slide 31 by screws. First support frames 3341 are respectively disposed at the left and right ends of the mounting plate 334. The upper ends of the first support frames 3341 are detachably fixedly connected to the mounting plate 334, and the lower ends of the first support frames 3341 are provided with third sliders 362 that cooperate with the third guide rails 361.

[0086] The fourth driving component includes a lead screw 371. Both ends of the lead screw 371 are rotatably connected to bearing seats 314 mounted on the second slide 31 via bearing assemblies. One end of the lead screw 371 is directly or via a second transmission mechanism connected to the power output end of the fourth motor 372. A second support frame 3342 is positioned on the mounting plate 334 between the two first support frames 3341. The upper end of the second support frame 3342 is detachably fixed to the mounting plate 334, and the lower end of the second support frame 3342 is provided with a detachable nut seat 3343. The nut 373, which mates with the lead screw 371, is fixedly connected to the nut seat 3343 by screws. The spiral grooves at both ends of the lead screw 371 rotate in opposite directions. When the lead screw 371 rotates under the drive of the fourth motor 372, the cooperation of the lead screw 371 and the nut 373 can drive the two striking components 33 to move towards each other or away from each other.

[0087] As one specific implementation method, according to Figure 1 In the coordinate system shown, in this embodiment, a fourth motor mount 315 is provided at the rear end of the second carriage 31. The fourth motor 372 is detachably fixed to the fourth motor mount 315. The power output end of the fourth motor 372 is connected to the rear end of the lead screw 371 through a second transmission mechanism. A cover 38 is provided on the outside of the second transmission mechanism. For example, the second transmission mechanism uses a synchronous belt 253 for transmission.

[0088] By designing the striking component 33 as a sliding structure and setting a fourth driving component, it can adapt to sheet materials of different lengths, thereby improving versatility.

[0089] As can be seen from the above description, the shuttle machine provided in this application embodiment, which is suitable for multi-station production lines, is divided into three main parts. These parts can be assembled separately and then assembled into a whole machine, thus achieving modular assembly, which facilitates installation and future maintenance.

[0090] The working process of a shuttle machine suitable for a multi-station production line, as provided in this application embodiment, is as follows:

[0091] First, the base lifting unit 1 automatically adjusts to the specified height according to the sheet material information and mold height, and the two patting components 33 adjust to the specified position before patting according to the sheet material information.

[0092] Second, the stacking robot places the sheet metal onto the centering and tapping unit 3. A material presence detection switch 325, installed on the centering and tapping unit 3, checks for the presence of material, while a double material detection switch 326 checks for any double material abnormalities. If an abnormality is detected, the machine stops and awaits manual intervention; otherwise, it proceeds to the next step.

[0093] Third, the second motor 15 and the third motor 26 are activated, thereby driving the centering and tapping assembly 3 to move along the material flow direction. At the same time, the centering and tapping assembly 3 is activated, thereby performing transverse and longitudinal tapping and centering on the material during the conveying process to complete the centering and positioning.

[0094] This application provides a shuttle machine suitable for multi-station production lines, employing a two-stage telescopic design. During operation, the second motor 15 and the third motor 26 drive the first carriage 21 and the second carriage 31 to move simultaneously. This not only reduces the floor space occupied in the retracted state but also increases operating speed, production efficiency, and production cycle time. Furthermore, the shuttle machine provided in this application allows for simultaneous centering and conveying processes. Compared to traditional shuttle machines and positioning devices that are separate devices, this effectively improves production efficiency and accelerates the production cycle time.
