Description

[0002] Vacuum pressing equipment is one of the most commonly used devices in flexographic printing technology. This equipment usually uses a hydraulic system to drive the worktable up and down to press the workpiece.

[0003] In existing technologies, the workpiece to be pressed is usually placed on the vacuum pressing equipment by manual operation or ordinary robot operation. However, manual operation is inefficient and poses significant safety hazards. Furthermore, since the workpiece generates static electricity after being pressed, it may stick to the upper template when the template is opened. This results in the workpiece being in an unstable position after being pressed by the vacuum press and having a large tilt angle. Therefore, ordinary robots cannot accurately pick up the workpiece stuck to the upper template, leading to a reduction in production efficiency. Summary of the Invention

[0072] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0073] Please refer to Figures 1-3 The present invention provides an automatic material handling device for use in conjunction with a pressing machine to complete material handling and / or material handling; the pressing machine includes a horizontal template and a inclined template, and the automatic material handling device includes: a material handling unit 1, a material handling unit 22, a support arm 3, a rotating platform 5, and a motor mounting base 4.

[0074] The material handling unit 1 is used to grab unpressed workpieces on the first conveyor belt and transport them to the horizontal template of the pressing machine for pressing;

[0075] The feeding unit 22 is used to grab the pressed workpiece and transport it to the second conveyor belt;

[0076] The material handling unit 1 includes a fixed suction cup bracket 1, the material dispensing unit 22 includes a rotating suction cup bracket 2, and the support arm 3 includes a support arm 3 body. The rotating suction cup bracket 2 is movably connected to the first end of the support arm 3 via a gear 205, the fixed suction cup bracket 1 is fixedly connected to the second end of the support arm 3, the first end of the motor mounting base 4 is connected to the support arm 3 body, and the second end of the motor mounting base 4 is connected to the first end of the rotating platform 5 to support and control the rotation of the support arm 3.

[0077] The rotating suction cup bracket 2 includes a first horizontal suction cup bracket 201 and a first inclined suction cup bracket 202, and the first horizontal suction cup bracket 201 and the first inclined suction cup bracket 202 are intersected at a first preset angle, wherein the first preset angle matches the angle between the horizontal template of the pressing machine and the inclined template of the pressing machine.

[0078] The first preset angle is characterized as the angle between the intersection lines formed by the surface of the first horizontal suction cup bracket 201 and the surface of the first inclined suction cup bracket 202.

[0079] The motor mounting base 4 includes a servo motor to control the rotation of the rotating platform 5.

[0080] Regarding the rotary suction cup bracket 2, in a specific embodiment, the shape of the rotary suction cup bracket 2 matches the pressing machine template; in one example, the first horizontal suction cup bracket 201 is arranged parallel to the first inclined suction cup bracket 202.

[0081] In the above scheme, the automatic picking and unloading of workpieces is achieved through the cooperation of the picking unit 1, the unloading unit 2 and the conveyor belt, avoiding the low efficiency of manual operation and improving production efficiency. In addition, since static electricity is generated after the workpiece is pressed, the pressing machine template may stick the workpiece to any surface of the template when the mold is opened. Therefore, the present invention designs the shape of the rotating suction cup bracket 2 to match the shape of the pressing machine template, so as to pick up the workpiece from different template surfaces.

[0082] For more information on the feeding unit 2, please refer to [link / reference needed]. Figure 3 The feeding unit 2 further includes: a first non-contact suction cup group 203 and a second non-contact suction cup group 204; the first non-contact suction cup group 203 is disposed on the first inclined suction cup bracket 202, and the second non-contact suction cup group 204 is disposed on the first horizontal suction cup bracket 201.

[0083] For more information about the material handling unit 1, please refer to [link / reference needed]. Figure 3 The material handling unit 1 further includes a second horizontal suction cup bracket 101, a second inclined suction cup bracket 102, and a third non-contact suction cup group 103. The second horizontal suction cup bracket 101 and the second inclined suction cup bracket 102 are intersected at a preset angle, and the third non-contact suction cup group 103 is disposed on the second horizontal suction cup bracket 101.

[0084] Regarding non-contact suction cup groups, in one example, three suction cups are used to form a suction cup group, and there is a gap between each suction cup. The non-contact suction cup group grasps the workpiece by its suction force, and the number of suction cups is not specifically limited.

[0085] In the above scheme, non-contact suction cups are used for picking up and placing materials, so that the workpiece remains flat and does not deform during the conveying process. In addition, the suction cup group is divided into several suction cups, with gaps between each suction cup and each suction cup is positioned to accurately grasp the workpiece. Compared with the scheme of setting suction cups on all surfaces of the rotating suction cup bracket 2, the present invention reduces the weight of the automatic picking and placing device while ensuring the grasping effect.

[0086] In a preferred embodiment, the automatic material handling device further includes a detection module, which is configured to:

[0087] Check whether there are any workpieces that have been pressed on the horizontal template of the pressing machine;

[0088] Detect whether the rotating suction cup bracket 2 has moved to the horizontal template of the press machine / the inclined template of the press machine / the second conveyor belt, or detect whether the fixed suction cup bracket 1 has moved to the horizontal template of the press machine / the first conveyor belt.

[0092] In a preferred embodiment, when the automatic loading and unloading device is used for unloading, the unloading occurs when there is a workpiece that has already been pressed on the horizontal template of the pressing machine.

[0093] The second non-contact suction cup group 204 is configured to: adsorb the workpiece that has been pressed on the horizontal template of the presser to the first horizontal suction cup bracket 201;

[0094] The rotating suction cup holder 2 is configured as follows:

[0095] The pressed workpiece is then transported onto the second conveyor belt.

[0096] In other preferred embodiments, when there are no pressed workpieces on the horizontal template of the pressing machine,

[0097] The first non-contact suction cup group 203 is configured to: adsorb the workpiece that has been pressed on the inclined template of the press machine to the first inclined suction cup bracket 202;

[0098] The rotating suction cup holder 2 is configured as follows:

[0099] The pressed workpiece is then transported onto the second conveyor belt.

[0100] In other embodiments, when the automatic loading and unloading device is used for unloading, the rotating platform 5 is configured as follows:

[0101] Rotate the support arm 3 by a third preset angle to drive the movement of the fixed suction cup bracket 1 and the rotating suction cup bracket 2;

[0102] The third preset angle is adapted to the position of the first conveyor belt, the second conveyor belt, the horizontal template of the pressing machine, and the inclined template of the pressing machine.

[0103] Regarding the tilting cylinder 206, in a preferred embodiment, the automatic material handling device further includes a tilting cylinder 206, which is located at the first end of the support arm 3 to rotate the rotating suction cup bracket 2.

[0104] The rotary suction cup holder 2 is also configured to:

[0106] The pressed workpiece is then transported onto the second conveyor belt.

[0107] The second preset angle is adapted to the position of the second conveyor belt.

[0108] Regarding the early warning module, in a preferred embodiment, the automatic material handling device further includes an early warning module, which is configured as follows:

[0109] When the rotating suction cup bracket 2 fails to move to the horizontal template of the press machine / the inclined template of the press machine / the second conveyor belt, the automatic material handling device is controlled to stop working and a warning is issued.

[0110] When the fixed suction cup bracket 1 fails to move to the horizontal template of the pressing machine / the first conveyor belt, the automatic material handling device is controlled to stop working and a warning is issued.

[0111] For specific implementation details, please refer to the following: Figure 3 The automatic material handling device further includes: a support frame, a linear module 6, a sliding base 7, and a ground guide rail 8; the first end of the support frame is connected to the second end of the rotating platform 5, the second end of the support frame is connected to the first end of the linear module 6, and the second end of the linear module 6 is connected to the sliding base 7 and the ground guide rail 8.

[0112] The linear module 6 is used to control the vertical movement of the automatic material handling device;

[0113] The sliding base 7 and the ground guide rail 8 are used to control the horizontal movement of the automatic material handling device.

[0114] The sliding base 7 includes casters, and the ground guide rail 8 includes a slide rail or a linear track. In one embodiment, taking a spatial rectangular coordinate system as an example, the sliding base 7 and the ground guide rail 8 move together to drive the automatic material handling device to move in the X and Y directions, and the linear module 6 controls the movement of the automatic material handling device in the Z direction.

[0115] Regarding the control module, in a preferred embodiment, the automatic material handling device further includes a control module, which is communicatively connected to the rotating platform 5, the linear module 6, the sliding base 7, and the ground guide rail 8 to control the movement of the automatic material handling device.

[0116] For specific embodiments, please refer to Figure 3 as well as Figure 4 The working process of the automatic material handling device is as follows:

[0117] 1. When the automatic material feeding device starts feeding, the servo motor installed in the motor mounting base works, causing the ball screw inside the support arm to drive the support arm to move in a straight line, so that the rotating suction cup bracket stops moving when it reaches the preset work position (i.e., the pressing machine template).

[0118] 2. The detection module begins to detect whether there are finished products that have been pressed on the horizontal template of the pressing machine:

[0119] (1) If the finished product that has been pressed is electrostatically attached to the inclined template of the pressing machine, the first non-contact suction cup group will perform the material collection work. The flipping cylinder will work to make the rotating suction cup bracket rotate 154° counterclockwise around the gear, so that the surface of the first inclined suction cup bracket will be flipped downward and wait for the support arm to run to the material release position (i.e. the second conveyor belt). The first non-contact suction cup group will cancel the suction force and perform the material release work to place the finished product that has been pressed on the fixed position of the second conveyor belt. The material release is completed and ready for subsequent work.

[0120] (2) If the finished product that has been pressed is on the horizontal template of the pressing machine, the second non-contact suction cup group will perform the material receiving work. The rotating suction cup bracket will maintain the initial horizontal state. The rotating platform will work to make the support arm and the rotating suction cup bracket rotate 90° clockwise around the center of the support arm. The servo motor, sliding base and linear module in the motor mounting base will work in coordination at the same time, so that the product reaches the unloading position (i.e. the second conveyor belt). The second non-contact suction cup group will cancel the suction force and perform the material release work to place the finished product that has been pressed on the fixed position of the second conveyor belt to complete the material release, in preparation for subsequent work.

[0121] 3. When the automatic material handling device is handling material, the servo motor in the motor mounting base rotates the support arm counterclockwise by 90 degrees along the center of the support arm, so that the fixed suction cup bracket reaches the loading position (i.e., the first conveyor belt). The linear module works in coordination to make the surface of the second horizontal suction cup bracket close to the unpressed product placed on the first conveyor belt. The third non-contact suction cup group on the second horizontal suction cup bracket begins to adsorb the unpressed product onto the fixed second horizontal suction cup bracket.

[0122] 4. The rotating platform rotates the support arm and the fixed suction cup bracket counterclockwise by 90° again, from the initial state to 180°, so that the fixed suction cup bracket extends into the horizontal template of the press machine. After the third non-contact suction cup group places the unpressed product on the horizontal template of the press machine, the support arm rotates clockwise by 90° to reach the loading position (i.e., the first conveyor belt), and enters the next loading cycle. Then it rotates clockwise by 90° to the horizontal template of the press machine, returns to the initial unloading state, and enters the unloading cycle. Finally, the complete loading and unloading cycle is completed.

[0123] The present invention also provides a vacuum pressing device, including the automatic material handling device described above.
