Technical Field

[0001] The utility model belongs to the field of transport tools, and in particular relates to a multi-station automatic transport mechanism. Background Art

[0002] In order to improve the production efficiency of products, current product production equipment is all fully automatic assembly line production equipment. This fully automatic assembly line production equipment is equipped with multiple process stations, each station is responsible for processing one process, and multiple processes are carried out simultaneously, saving production time. When the workpiece completes a process at a certain station, it needs to enter the next station to complete the next process. The current method is to set a movable mechanical claw between every two stations to transport the workpiece on the previous station to the next station. However, this design structure requires a handling device to be set between two adjacent stations. Generally, the handling device is composed of a linear guide slider pair and a mechanical claw, which makes the overall length of the production equipment very long, occupies a large space, and it is difficult to coordinate so many handling devices during transportation. In case one of the handling devices fails, the workpiece on the previous station of the handling device will not be able to be transferred to the next station, causing the entire production line to be idle and production to stagnate. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the current multi-process workstation production equipment has a workpiece handling device between each adjacent workstation, which makes the overall length of the production equipment longer, and the multiple handling devices are difficult to coordinate, the transfer connection is poor, and it takes more time.

[0004] In order to solve the above technical problems, the utility model provides a multi-station automatic handling mechanism, including a bracket, a lifting device, a stepping horizontal displacement device, a fixed rod and a plurality of grippers, the bottom of the bracket is fixed on the workbench, the fixed rod is connected to the top of the bracket through the lifting device and the horizontal displacement device, the fixed rod is horizontally arranged, and a plurality of grippers are fixed at intervals below the fixed rod, and the distance between two adjacent grippers is L. The lifting device enables the grippers to be lifted and lowered along the Z-axis direction, and the stepping horizontal displacement device enables the grippers to step and displace a stroke S each time, and L=S.

[0005] Preferably, the lifting device is a vertical electric slide rail, the stepping horizontal displacement device is a horizontal electric slide rail, the fixing rod is fixed to the moving module of the vertical electric slide rail, and the vertical electric slide rail is fixed to the moving module of the horizontal electric slide rail.

[0006] Preferably, the fixed rod is connected to the movable module of the vertical electric slide rail via a T-block and a vertical plate, the vertical plate is fitted with the front side of the vertical electric slide rail, one end of the vertical plate is fixed to the movable module of the vertical electric slide rail, and the other end of the vertical plate is fixed to the rear side of the fixed rod, the T-block includes a head cross bar and a tail vertical bar, the head cross bar is fixed to the top surface of the fixed rod, and the tail vertical bar is fitted and fixed to the vertical plate.

[0007] Preferably, the hand gripper includes a finger cylinder, an interface shell clamp and a rubber strip claw, the interface shell clamp includes a first finger sleeve and a second finger sleeve arranged opposite to each other on the left and right, the finger cylinder is provided with one end of a finger facing downward, the first finger sleeve and the second finger sleeve are respectively fixed on the two clamping fingers of the finger cylinder, the rubber strip claw is fixed on the cylinder body of the finger cylinder, and two clamping fingers are spaced apart at the bottom of the rubber strip claw, and the gap between the two clamping fingers constitutes a bayonet.

[0008] Preferably, a connecting plate is fixed to the top of the finger cylinder, and the connecting plate is also connected to the fixing rod.

[0009] Preferably, two rubber strip clamping claws are provided, which are respectively fixed on the front and rear sides of the finger cylinder body.

[0010] The technical solution of the utility model has the following beneficial effects:

[0011] The handling mechanism of the utility model is an integral structure, which is arranged above the workstation, including a fixed rod, on which a plurality of hand grips are arranged. The hand grips are raised and lowered by the lifting and lowering of the fixed rod. When the hand grips are lowered, it is convenient for the hand grips to grab the workpieces. When the hand grips are raised, it is convenient for the hand grips to interfere with other parts of the production equipment when they are stepping and moving. The hand grips are step-displaced by the step-by-step displacement of the fixed rod so that the workpieces are transferred from one workstation to the workstation of the next process each time. Since the utility model is installed above the workstation and the hand grips are integrated together, the problem of a longer overall length of the production equipment caused by setting a handling device between every two adjacent workstations is avoided. In addition, the step-by-step displacement of the utility model has only one driving source, so there will be no problem of poor connection between each other during transportation, thus ensuring synchronization and improving production efficiency.

[0021] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] The utility model provides a multi-station automatic handling mechanism, comprising a bracket 1, a lifting device and a stepping horizontal displacement device, a fixed rod 4 and a plurality of hand grips 5, the bottom of the bracket 1 is fixed on a workbench, the fixed rod 4 is connected to the top of the bracket 1 through the lifting device and the horizontal displacement device, the fixed rod 4 is horizontally arranged, a plurality of hand grips 5 are fixedly arranged below the fixed rod 4 at intervals, the interval between two adjacent hand grips 5 is L, the lifting device enables the hand grips 5 to be lifted and lowered along the Z-axis direction, and the stepping horizontal displacement device enables the hand grips 5 to step and displace a stroke S each time, and L=S.

[0023] The utility model is applied to automated production equipment with multiple stations of the assembly line. Its main function is to transport the processed parts or assembly parts on the previous process station to the next process station, and multiple stations are transported at the same time. The distance between two adjacent stations is A, L=S=A. In the initial state, the first hand gripper 5 corresponds to the first station, the second hand gripper 5 corresponds to the second station... and so on. After each hand gripper 5 grabs the corresponding processed part (assembly), it first steps and moves a stroke to move all the processed parts (assemblies) to the subsequent station. All the processed parts are then processed in the corresponding process. Then the hand gripper 5 grabs the corresponding processed part (assembly) again, and then steps and moves a stroke again, and again moves all the processed parts (assemblies) to the station of the next process. Of course, in this process, the finished product completed at the station of the last process can be transferred out by an additional transfer device, or it can be transferred out by the last clamp of the utility model.

[0024] Specifically, the lifting device is a vertical electric slide 2, the stepping horizontal displacement device is a horizontal electric slide 3, the fixed rod 4 is fixed to the moving module of the vertical electric slide 2, and the vertical electric slide 2 is fixed to the moving module of the horizontal electric slide 3. The electric slides are all prior art products, so the description of the utility model will not elaborate on their structure and working principle in detail. When the hand grip 5 needs to grab the workpiece (assembly), the moving module of the vertical electric slide 2 slides down, directly driving the fixed rod 4 to descend, so that the hand grip 5 can grab the workpiece (assembly). When the hand grip 5 needs to move the workpiece, the moving module of the vertical electric slide 2 rises again to prevent the hand grip 5 from interfering with the automation equipment components below when moving. When the hand grip 5 needs to move the workpiece (assembly), the moving module of the horizontal electric slide 3 moves horizontally, directly driving the vertical electric slide 2 to move horizontally, and indirectly driving the fixed rod 4 to move horizontally.

[0025] Specifically, the fixed rod 4 is connected to the movable module of the vertical electric slide rail 2 through a T-block 6 and a vertical plate 7. The vertical plate 7 is fitted with the front side of the vertical electric slide rail 2. One end of the vertical plate 7 is fixed to the movable module of the vertical electric slide rail 2. The other end of the vertical plate 7 is fixed to the rear side of the fixed rod 4. The T-block 6 includes a head cross bar and a tail vertical bar. The head cross bar is fixed to the top surface of the fixed rod 4, and the tail vertical bar is fitted and fixed to the vertical plate 7.

[0026] The hand gripper 5 includes a finger cylinder 51, an interface shell clamping claw 52 and a rubber strip clamping claw 53. The interface shell clamping claw 52 includes a first finger sleeve 521 and a second finger sleeve 522 which are arranged opposite to each other on the left and right sides. The finger cylinder 51 is provided with one end of a finger facing downward. The first finger sleeve 521 and the second finger sleeve 522 are respectively fixed on the two clamping fingers of the finger cylinder 51. The rubber strip clamping claw 53 is fixed on the cylinder body of the finger cylinder 51. Two clamping fingers are arranged at intervals at the bottom of the rubber strip clamping claw 53. The gap between the two clamping fingers forms a bayonet 531. After the hand gripper 5 is lowered, the first finger sleeve 521 and the second finger sleeve 522 are driven by the finger cylinder 51 to approach each other, clamping the side of the interface shell on the assembly. When the hand gripper 5 is lowered, the rubber strip clamping claw 53 is also driven to lower. The bayonet 531 of the rubber strip clamping claw 53 is just clamped on the top of the rubber strip. The interface shell clamping claw 52 and the rubber strip clamping claw 53 jointly apply a grasping force to the workpiece (assembly) to prevent the problem of the assembly falling apart when only one of the components is grasped.

[0027] A connecting plate 8 is fixed on the top of the finger cylinder 51 of the utility model, and the connecting plate 8 is also connected to the fixing rod 4. The finger cylinder 51 of the utility model is fixed to the fixing rod 4 through the connecting plate 8, which is equivalent to fixing the hand grip 5 on the fixing rod 4 through the connecting plate 8.

[0028] In order to balance the front and rear forces of the hand grip 5 and ensure stable grasping of the assembly, the utility model has two rubber strip claws 53, which are respectively fixed on the front and rear sides of the cylinder body of the finger cylinder 51.

[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
