Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to a sheet separation and feeding mechanism. Background Technology

[0002] When the thin sheets are fed through vacuum adsorption, the phenomenon of sheet stacking is prone to occur, that is, one or more thin sheets are simultaneously below the sheet adsorbed by the vacuum adsorption head. The feeding stability is poor and it is easy to affect the next process, which needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a sheet separation and feeding mechanism, including a displacement mechanism, a vacuum adsorption mechanism, a mounting platform, and a pushing mechanism. The displacement mechanism is located on one side of the mounting platform, and the vacuum adsorption mechanism is located at the moving end of the displacement mechanism. The displacement mechanism moves the vacuum adsorption mechanism horizontally and vertically. The mounting platform is provided with a mounting area for the vacuum adsorption mechanism to discharge materials. The pushing mechanism includes a telescopic mechanism and a pushing block located at its moving end. The telescopic mechanism drives the pushing block through the mounting area to push the workpiece out of the mounting area. The mounting platform is provided with an air outlet. When the displacement mechanism moves the vacuum adsorption mechanism to a predetermined position, the air outlet sprays air into the adsorption end of the vacuum adsorption mechanism.

[0005] In use, the vacuum adsorption mechanism is moved by the displacement mechanism, and the vacuum adsorption mechanism adsorbs the sheet. After the displacement mechanism moves the sheet to the placement area, the air outlet sprays air to make the sheet that was superimposed during vacuum adsorption fall down. The pusher block is moved by the telescopic mechanism in the pushing mechanism to push out the sheet that has fallen in the placement area. After that, the sheet that was actually adsorbed by the vacuum adsorption mechanism can fall in the required position in the placement area, which improves the stability of feeding.

[0006] Furthermore, the displacement mechanism includes a longitudinal displacement mechanism, a horizontal displacement mechanism, and a fixed frame. The horizontal displacement mechanism is mounted on the fixed frame, and the fixed frame is located at the moving end of the longitudinal displacement mechanism. A vacuum adsorption mechanism is located at the moving end of the horizontal displacement mechanism. It is a bidirectional displacement type, and the position of the vacuum adsorption mechanism can be adjusted as needed. Of course, a three-dimensional displacement mechanism can also be selected as the displacement mechanism, depending on the requirements.

[0007] Furthermore, a groove is provided on the top surface of the placement platform within the placement area, and an air outlet is provided in the groove. The air outlet faces upward, and the air outlet is reasonably arranged to facilitate blowing out the thin sheets stacked during adsorption.

[0008] Furthermore, the system also includes a feeding mechanism, which comprises a servo shifting mechanism, a material bar, and a pusher plate. The pusher plate is located at the moving end of the servo shifting mechanism, and the material bar passes through a hole formed in the pusher plate. The servo shifting mechanism moves the pusher plate longitudinally, pushing the workpiece fitted onto the material bar upwards. The material bar is within the working range of the vacuum adsorption mechanism. For example, a thin sheet can be pre-fitted onto the material bar, and then the vacuum adsorption mechanism adsorbs the sheet from the material bar and moves it to the placement area for unloading. The servo shifting mechanism can move the pusher plate to continuously move the sheet fitted onto the material bar upwards for easier adsorption. The addition of a feeding mechanism in this solution helps to further improve efficiency.

[0009] Furthermore, the vacuum adsorption mechanism consists of two sets. The displacement mechanism moves one vacuum adsorption mechanism to adsorb the workpiece at the material bar while the other vacuum adsorption mechanism simultaneously adsorbs the workpiece at the placement area. The displacement mechanism moves the vacuum adsorption mechanism from the material bar to the placement area and moves the vacuum adsorption mechanism at the placement area to a predetermined position. The dual adsorption ends can simultaneously complete the adsorption of the sheet at the material bar and the adsorption of a single sheet at the placement area, which helps to improve efficiency.

[0010] Furthermore, it also includes a carrier plate, on which the servo shifting mechanism and displacement mechanism are both mounted. A support plate is mounted on the carrier plate, and a telescopic mechanism is mounted on the support plate. The telescopic mechanism is located on one side of the mounting platform. The carrier plate is added to centrally mount the servo shifting mechanism, etc., which facilitates movement and installation.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, this sheet separation and feeding mechanism includes a displacement mechanism 1, a vacuum adsorption mechanism 5, a mounting platform 3, and a pushing mechanism 2. The displacement mechanism 1 can be any common bidirectional or tridirectional type; this example demonstrates a bidirectional displacement mechanism, which includes a longitudinal displacement mechanism 12, a horizontal displacement mechanism 10, and a fixing frame 11. The horizontal displacement mechanism 10 is mounted on the fixing frame 11. The horizontal displacement mechanism can be a common cylinder. The fixing frame 11 is mounted at the moving end of the longitudinal displacement mechanism 12, and the vacuum adsorption mechanism 5 is mounted at the moving end of the horizontal displacement mechanism 10. In this example, the vacuum adsorption head is used as the vacuum adsorption mechanism, with the vacuum adsorption head facing downwards. In use, the horizontal displacement mechanism moves the vacuum adsorption mechanism horizontally, while the longitudinal displacement mechanism moves the horizontal displacement mechanism vertically up and down, adjusting the height of the vacuum adsorption mechanism accordingly.

[0023] A displacement mechanism 1 is installed on one side of the mounting platform 3. A predetermined area, such as the end of the mounting platform 3, is designated as the mounting area 31 for the vacuum adsorption mechanism to discharge material. A pushing mechanism 2 is installed on one side of the mounting area 31. The pushing mechanism 2 includes a telescopic mechanism 21 and a push block 22 fixed at its moving end. The telescopic mechanism 21 drives the push block 22 through the mounting area to push out the sheet in the mounting area.

[0024] An air outlet 7 is installed on the placement platform 3. A groove is formed on the top surface of the placement platform within the placement area, and the air outlet 7 is fixed in the groove with its outlet facing upwards. When the displacement mechanism 1 moves the vacuum adsorption mechanism 5 to the predetermined position, air is blown from the air outlet towards the adsorption end of the vacuum adsorption mechanism. During adsorption, the stacked sheets are loosened and fall into the placement area. The horizontal displacement mechanism moves the push block horizontally, pushing out the sheets that have fallen into the placement area. Afterwards, the displacement mechanism can adjust the position of the vacuum adsorption mechanism so that the adsorbed sheets fall into the predetermined position in the placement area. Alternatively, the air outlet can be installed on one side of the placement area, blowing air from the side, depending on the requirements.

[0025] To improve efficiency, a feeding mechanism can be added. The feeding mechanism 4 includes a servo shifting mechanism 41, a material rod 43, and a push plate 42. The servo shifting mechanism is a common screw displacement type. The push plate 42 is horizontally installed at the moving end of the servo shifting mechanism 41. The material rod 43 is located on one side of the servo shifting mechanism 41 and passes through the hole formed on the push plate 42. The material rod 43 is within the working range of the vacuum adsorption mechanism. The servo shifting mechanism moves the push plate longitudinally, and the push plate pushes the thin sheet on the material rod to move upward, which facilitates the adsorption of the vacuum adsorption mechanism.

[0026] In use, if the sheet is pre-attached to the material bar, the displacement mechanism moves the vacuum adsorption mechanism to adsorb the sheet at the material bar and moves it to the placement area for material discharge.

[0027] To further improve efficiency, two sets of vacuum adsorption mechanisms 5 can be selected. For example, two sets of vacuum adsorption mechanisms 5 can be arranged side by side at the moving end of the horizontal displacement mechanism 10. The position between the two sets of vacuum adsorption mechanisms is set according to the distance between the placement area and the material bar. In use, if the displacement mechanism moves one vacuum adsorption mechanism to adsorb the workpiece at the material bar and the other vacuum adsorption mechanism simultaneously adsorbs the workpiece at the placement area, when the displacement mechanism moves the vacuum adsorption mechanism from the material bar to the placement area, the other vacuum adsorption mechanism moves from the placement area to other predetermined positions to feed the sheet, thereby improving efficiency.

[0028] For ease of installation, a carrier plate 6 is added in this example. The servo shifting mechanism 41 and the longitudinal shifting mechanism 12 in the displacement mechanism 1 are both fixed at the horizontal part of the carrier plate 6. The mounting platform 3 is installed at the longitudinal part of the carrier plate. The support plate on the side of the carrier plate 6 fixes the telescopic mechanism 21 in the pushing mechanism. The telescopic mechanism 21 is located on one side of the mounting platform 3.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
