Description

Technical Field

[0001] The utility model relates to a vacuum adsorption and transporting device based on a robot. Background Art

[0002] When the product is automatically produced, the sheet needs to be transferred from the conveyor line to the processing line. However, the current transfer device (or robot, etc.) can only grab one product on the conveyor line at a time and then automatically transfer it to the processing line at a fixed point, so there is a problem of low efficiency.

[0003] The key technical difficulty lies in that the slices conveyed on the conveyor line are arranged close to each other, while the slices on the processing line are arranged at intervals. Therefore, the existing transfer device cannot grab two slices that are close to each other on the conveyor line at one time and then place them on the processing line at intervals. Utility Model Content

[0004] The utility model provides a production line to solve the technical problem that the existing transfer device (or manipulator, etc.) cannot grab two thin slices closely distributed on the conveyor line at one time and then place them on the processing line at intervals.

[0005] The utility model provides a robot-based vacuum adsorption and transfer device, comprising a robot and a clamp; the characteristics are: the clamp comprises a connecting seat, a crossbeam, two driving cylinders, two slides and two flat plates; the connecting seat is fixedly connected to the execution end of the robot; the middle part of the crossbeam is fixedly connected to the connecting seat; a transverse guide rail is provided on the crossbeam; the two slides are both slidably matched with the transverse guide rail; the two driving cylinders are fixedly installed on the connecting seat and / or the crossbeam and are symmetrically distributed; the output ends of the two driving cylinders are respectively fixedly connected to the two slides; the two flat plates are respectively fixed to the lower ends of the two slides; and each of the flat plates is provided with a plurality of suction cups.

[0006] With the above scheme, the robot is used to drive the fixture to transfer between the conveyor line and the processing line; and the fixture is used to suck and release the thin slices. The key is: when the fixture is displaced to the conveyor line, the two driving cylinders of the fixture drive the two slides to move toward each other along the transverse guide until they are in place, and then the suction cups on each of the flat plates are started to absorb at the same time, which can simultaneously suck two thin slices that are closely distributed (at this time, the two thin slices on the fixture are closely distributed); then the fixture is transferred to the processing line by starting the robot; then the two driving cylinders of the fixture are started to drive the two slides to move away from each other along the transverse guide until they are in place (at this time, the two thin slices on the fixture are spaced apart), and then the suction cups on each of the flat plates are started to release at the same time to place the two thin slices on the processing line at intervals. Therefore, the technical solution can not only grab two thin slices that are closely distributed on the conveyor line at one time, but also place them on the processing line at intervals, which can double the production efficiency.

[0007] Furthermore, each of the flat plates is provided with at least one suction cup.

[0008] Furthermore, the driving cylinder is a telescopic cylinder.

[0009] Furthermore, the robot is a four-axis robot.

[0010] Furthermore, the transverse guide rail is fixed on the lower surface of the beam; the two driving cylinders are located above the beam and are symmetrically distributed on both sides of the connecting seat; the output end of the driving cylinder is fixedly connected to the slide seat through an intermediate connecting plate; and a avoidance groove is provided on the intermediate connecting plate.

[0011] Furthermore, two limit blocks are symmetrically provided at both ends of the crossbeam.

[0012] Beneficial effects of the utility model:

[0013] First, the utility model can grab two thin sheets that are closely distributed on the conveyor line at one time and then place them on the processing line at intervals, which can double the production efficiency;

[0014] Secondly, the overall shape of the clamp of the utility model becomes extremely small and compact, while being able to work normally, and the structure is optimized and more reasonable to ensure that the two sucked sheets move more smoothly when the distance is changed, without shaking, and more accurately when the distance changes.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example: See Figure 1-4 , a robot-based vacuum adsorption transfer device, including a robot 1 and a clamp.

[0021] The robot 1 is used to drive the fixture 2 to transfer between a conveying line (not shown in the conveying line diagram and belongs to the existing structure) and a processing line (not shown in the processing line diagram and belongs to the existing structure). In this embodiment, the robot 1 is a four-axis robot.

[0022] In other embodiments, the robot 1 is a five-axis robot or a six-axis robot.

[0023] The clamp 2 is used to suck and release the thin sheet (the thin sheet in the figure is not shown and it belongs to the existing structure).

[0024] In this embodiment, see Figure 3 The fixture 2 includes a connecting seat 2-1, a crossbeam 2-2, two driving cylinders 2-3, two slides 2-4 and two flat plates 2-5; the connecting seat 2-1 is fixedly connected to the execution end of the robot 1; the middle part of the crossbeam 2-2 is fixedly connected to the connecting seat 2-1; a transverse guide rail 2-21 is fixedly provided on the crossbeam 2-2; the two slides 2-4 are both slidably matched with the transverse guide rail 2-21; the two driving cylinders 2-3 are fixedly installed on the connecting seat 2-1 and / or the crossbeam 2-2 and are symmetrically distributed; the output ends of the two driving cylinders 2-3 are respectively fixedly connected to the two slides 2-4; the two flat plates 2-5 are respectively fixed to the lower ends of the two slides 2-4; each of the flat plates 2-5 is provided with a plurality of suction cups 2-6.

[0025] In this embodiment, the output ends of the two driving cylinders 2 - 3 are arranged in back-to-back orientation.

[0026] Furthermore, at least 4 to 12 suction cups 2-6 are provided on each of the flat plates 2-5.

[0027] In this embodiment, eight suction cups 2-6 are installed on the flat plate 2-5.

[0028] Furthermore, the driving cylinder 2-3 is a telescopic cylinder.

[0029] Furthermore, the transverse guide rail 2-21 is fixed on the lower surface of the crossbeam 2-2; the two driving cylinders 2-3 are both located above the crossbeam 2-2 and symmetrically located on the left and right sides of the connecting seat 2-1; the output ends of the two driving cylinders 2-3 are respectively fixedly connected to the two slide seats 2-4 through two intermediate connecting plates 2-7; the intermediate connecting plate 2-6 is provided with a avoidance groove 2-71; specifically, the avoidance groove 2-71 is a C-shaped groove. Since the driving cylinder 2-3 is above the transverse guide rail 2-21, and the transverse guide rail 2-21 is below the transverse guide rail 2-21, the intermediate connecting plate 2-6 can slide normally to avoid the position. In this way, the overall shape of the clamp can become extremely small and very compact, while being able to work normally, with an optimized and more reasonable structure, and at the same time ensuring that the two sucked thin sheets move more smoothly and without shaking when changing distance;

[0030] Specifically, a guide groove 2-41 for sliding cooperation with the transverse guide rail 2-21 is provided at the upper end of the slide seat 2-4.

[0031] Furthermore, two limit blocks 2-8 are symmetrically fixed at the left and right ends of the cross beam 2-2. When the two driving cylinders 2-3 drive the two slides 2-4 to move away from each other along the transverse guide rails 2-21, the two intermediate connecting plates 2-6 are blocked by the two limit blocks 2-8 and are limited in place, which can ensure that the distance between the two sheets sucked by the suction cups 2-6 on the two flat plates 2-5 is very accurate when it is enlarged and in place each time.

[0032] The working principle of this embodiment is as follows: when the fixture 2 is displaced to the conveyor line, the two driving cylinders 2-3 of the fixture 2 work and drive the two slides 2-4 to move toward each other along the transverse guide rail 2-21 until they are in place (at this time, the output end of the driving cylinder 2-3 retracts into place), and at this time, the two flat plates 2-5 are very close to or just in contact with each other; then, the suction cups 2-6 on each flat plate 2-5 are started to work simultaneously and absorb the two thin sheets that are closely distributed at the same time. At this time, the two thin sheets absorbed by the fixture are closely distributed; then, the fixture 2 is transferred to the processing line by starting the robot 1; then, the robot 1 is started. The two driving cylinders 2-3 of the clamp 2 work and drive the two slides 2-4 to move away from each other along the transverse guide rail 2-21 until they are in place (at this time, the output end of the driving cylinder 2-3 is extended to the position). At this time, the two flat plates 2-5 on the clamp are spaced apart so that the two sucked sheets are spaced apart and the spacing is a constant value; then the suction cups 2-6 on each flat plate 2-5 are started and released at the same time to place the two sheets on the processing line at intervals. Therefore, this embodiment can grab two sheets that are closely distributed on the conveyor line at one time and then place them on the processing line at intervals, which can double the production efficiency.

[0033] Therefore, the utility model can realize the simultaneous grabbing of two adjacent workpieces on the conveyor line, and then transfer and place them on the processing line at intervals after changing the distance, which can meet the work use requirements, replace manual operation and improve production efficiency exponentially.

[0034] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
