Description

Technical Field

[0001] The utility model relates to a conveying device, in particular to a workpiece separating mechanism and a hot bending machine. Background Art

[0002] Before sheet processing, it is necessary to separate stacked sheets. The traditional separation method is manual material separation, which has low operation efficiency and high labor cost. With the development of technology, currently, a movable manipulator is set up to separate the sheet located on the topmost side by the manipulator. However, for sheets such as mylar sheets and insulating sheets, due to reasons such as oil and static electricity, the sheets will adsorb to each other. When using this method to separate and remove the stacked workpieces, it is easy to bring out the sheets on its bottom side, resulting in situations such as material jamming and simultaneous processing of multiple sheets in subsequent production. Therefore, there is an urgent need for a mechanism that can better separate stacked sheets upward. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a workpiece separating mechanism and a hot bending machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or creation condition.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A workpiece separating mechanism includes a frame, on which are provided: a loading plate; a backing plate located on one side of the loading plate, and a separation baffle extending upward above the loading plate is connected to the top side of the backing plate; a transfer assembly having a transfer end that can move downward close to the loading plate or upward away from the loading plate.

[0006] This technical solution has at least the following beneficial effects: Place the stacked sheets on the loading plate. When it is necessary to separate the sheets, the transfer end in the transfer assembly moves downward close to the loading plate to move the sheet located on the topmost side upward. During the upward movement of the sheet, the side of the sheet will pass by the separation baffle. Under the interference of the separation baffle on the sheet, the side of the sheet will elastically deform downward. At this time, for two mutually adsorbed sheets, the sheet located on the topmost side can continue to move upward under the action of the transfer end, while the sheet located on the second topmost side cannot continue to move upward due to the obstruction of the separation baffle. In this way, two mutually adsorbed sheets can be effectively separated, realizing the individual upward feeding of stacked sheets, which is also applicable to sheets with oil and static electricity adsorption, and has higher working stability.

[0007] As a further improvement of the above technical solution, the frame is also provided with an air blowing pipe, which is located beside the separation baffle, one end of which is connected to an air source, and the other end of which is arranged toward the top of the loading plate. When the mutually adsorbed sheets pass upward through the separation baffle, a gap will be formed between the two. At this time, the air source blows air toward the sides of the sheets through the air blowing pipe, and the airflow passes through the two sheets from the gap, which can further separate the two sheets from each other, further improving the effect of separating the two sheets from each other.

[0008] As a further improvement of the above technical solution, the end of the blowing pipe away from the air source is arranged toward the top of the loading plate and inclined downward. When the blowing pipe blows air, an airflow blowing downward can be formed. When the airflow passes through the two sheets from the gap, the sheet located on the secondary top side can be further blown downward, thereby further improving the effect of separating the two sheets from each other.

[0009] As a further improvement of the above technical solution, the frame is also provided with a first lifting drive member, which is driven by a pressure rod, which is located above the loading plate, and the first lifting drive member can drive the pressure rod to move downward toward the loading plate or upward away from the loading plate. Before separating the sheets, the first lifting drive member drives the pressure rod to move downward to a position where the topmost sheet is away from the separation baffle, at which time the stacked sheets can be limited up and down. When separating the sheets, the transfer end pulls up an end position of the topmost sheet and passes over the separation baffle, and then the first lifting drive member drives the pressure rod to move upward, so that the transfer end can separate and move the topmost sheet upward. In this way, the pressure rod is used to keep the limit when the sheet uses the separation baffle, which is conducive to avoiding the problem that the sheet located on the secondary top side moves out of the stacked sheets when it falls, and keeps the sheets neatly stacked.

[0010] As a further improvement of the above technical solution, the loading plate extends downwardly at an angle close to the backing plate. The inclined loading plate can facilitate the stacked sheets to lean against the backing plate, which is conducive to stacking and arranging the sheets more neatly.

[0011] As a further improvement of the above technical solution, an electric screw is provided between the frame and the loading plate, and the electric screw is driven to connect the loading plate, and the electric screw can drive the loading plate to move up and down. When the transfer end moves out a sheet, the electric screw can drive the loading plate to move up by the height of a sheet, so that the transfer end reaches the topmost sheet after moving down the same distance each time, and transfers and adsorbs the topmost sheet, thereby improving the stability during operation.

[0012] As a further improvement of the above technical solution, the transfer assembly includes a second lifting drive, a lifting plate and a vacuum chuck. The second lifting drive is arranged on the frame. The second lifting drive is drivingly connected to the lifting plate. The second lifting drive can drive the lifting plate to move up and down. The vacuum chuck is connected to the lifting plate, and the vacuum chuck is the transfer end. The second lifting drive can provide a driving force for the vacuum chuck to move in the up and down direction. When it is necessary to transfer the sheet material, the second lifting drive drives the vacuum chuck to move down to the sheet material at the topmost side, and then drives the vacuum chuck to move up to adsorb and separate the sheet material at the topmost side.

[0013] As a further improvement of the above technical solution, the transfer assembly further includes a translation drive and a translation plate. The translation drive is connected to the frame. The translation drive is drivingly connected to the translation plate. The translation drive can drive the translation plate to move in a direction close to or away from the loading plate. The second lifting drive is connected to the translation plate. A translation drive for driving the vacuum chuck to move translationally is also arranged on the frame. After the vacuum chuck lifts and separates the sheet material, then the translation drive drives the translation plate to move in a direction away from the loading plate to transfer the sheet material to the next working station, and then the translation drive drives the translation plate to move back to the original position in a direction close to the loading plate.

[0014] As a further improvement of the above technical solution, limiting plates are arranged on both sides of the frame in the width direction of the loading plate. The limiting plates on both sides of the loading plate can limit the stacked sheet materials, further improving the neatness of the stacked sheet materials during discharging and preventing scattering.

[0015] As a further improvement of the above technical solution, a detection sensor is arranged on the backing plate. The detection sensor is configured to detect whether there is a workpiece on the loading plate. During operation, the detection sensor detects whether there is still a workpiece, that is, a sheet material, on the loading plate, so as to facilitate the replenishment operation of the loading plate by manual or mechanical means.

[0016] A hot bending machine includes the above workpiece separating mechanism.

[0017] This technical solution has at least the following beneficial effects: In this hot bending machine, the above workpiece separating mechanism is used to separate the sheet materials, and two mutually adsorbed sheet materials can be effectively separated, realizing the individual upward feeding of the stacked sheet materials. It is also applicable to sheet materials with oil and electrostatic adsorption, and the working stability is higher. Description of the Drawings

Specific embodiments

[0022] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts all fall within the scope of protection of the present utility model. In addition, all the connection relationships mentioned in the text do not refer only to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflicting with each other.

[0023] Referring to Figure 1 , a workpiece separation mechanism includes a frame 100, and the following are provided on the frame 100: a loading plate 200; a backing plate 300, located on one side of the loading plate 200, and a separation baffle 310 extending upward above the loading plate 200 is connected to the top side of the backing plate 300; a transfer assembly having a transfer end that can move downward close to the loading plate 200 or move upward away from the loading plate 200.

[0024] As described above, when the stacked sheets are placed on the loading plate 200 and it is necessary to separate the sheets, the transfer end in the transfer assembly moves downward close to the loading plate 200 to lift the topmost sheet upward. During the upward movement of the sheet, the side of the sheet will pass by the separation baffle 310. Under the interference of the separation baffle 310, the side of the sheet will elastically deform downward. At this time, for two mutually adsorbed sheets, the topmost sheet can continue to move upward under the action of the transfer end, while the second topmost sheet cannot continue to move upward due to the obstruction of the separation baffle 310. In this way, the two mutually adsorbed sheets can be effectively separated, realizing the individual upward feeding of the stacked sheets. This is also applicable to sheets with oil or electrostatic adsorption, and the working stability is higher.

[0025] To better separate the two adsorbed sheets from each other, as Figure 2 shown, in this embodiment, a blowing pipe 400 is further provided on the frame 100. The blowing pipe 400 is located beside the separation baffle 310. One end of the blowing pipe 400 is connected to a gas source, and the other end of the blowing pipe 400 is arranged facing upward above the loading plate 200. When the mutually adsorbed sheets pass upward through the separation baffle 310, a gap will be formed between them. At this time, the gas source blows air to the side of the sheet through the blowing pipe 400, and the air flow passes through the two sheets from the gap, which can further separate the two sheets from each other and further improve the effect of separating the two sheets. In practical applications, for relatively thick sheets, they can be separated without blowing air, while for relatively thin sheets, the two mutually adsorbed sheets can be further separated by blowing air.

[0026] The blowing pipe 400 can blow air horizontally above the loading plate 200. In order to use the air flow to assist in keeping the sheet positioned on the stacked sheets, in this embodiment, the end of the blowing pipe 400 away from the gas source is arranged facing upward above the loading plate 200 and inclined downward. When the blowing pipe 400 blows air, an inclined downward air flow can be formed. When the air flow passes through the two sheets from the gap, it can further blow the second topmost sheet downward, thereby further improving the effect of separating the two sheets from each other.

[0027] In order to better keep the sheets neatly arranged on the loading plate 200, in the present embodiment, a first lifting drive member is further provided on the frame 100, and the first lifting drive member is driven and connected to a pressure rod 500, and the pressure rod 500 is located above the loading plate 200. The first lifting drive member can drive the pressure rod 500 downward toward the loading plate 200 or upward away from the loading plate 200. Before separating the sheets, the first lifting drive member drives the pressure rod 500 to move downward to a position where the topmost sheet is away from the separation baffle 310. At this time, the stacked sheets can be limited up and down. When separating the sheets, the transfer end pulls up one end position of the topmost sheet and passes over the separation baffle 310. Then the first lifting drive member drives the pressure rod 500 to move upward again, so that the transfer end can separate and move the entire topmost sheet upward. In this way, the pressure rod 500 is used to keep the sheet limited when it passes through the separation baffle 310, which is conducive to avoiding the problem of the sheet on the second top side moving out of the stacked sheets when it falls, and keeping the sheets stacked neatly.

[0028] The loading plate 200 can be placed horizontally, and in order to better arrange the stacked sheets on one side of the backing plate 300, in this embodiment, the loading plate 200 extends downwardly in a direction close to the backing plate 300. The inclined loading plate 200 can facilitate the stacked sheets to be pressed against the backing plate 300, which is conducive to stacking and arranging the sheets more neatly.

[0029] When the sheet is moved out, the height of the entire stack of sheets on the loading plate 200 will be reduced. At this time, the transfer end can be controlled to move down further to ensure the adsorption of the topmost sheet. In this embodiment, the stacked sheets are raised upward. Specifically, an electric screw 210 is provided between the frame 100 and the loading plate 200. The electric screw 210 is driven to connect the loading plate 200, and the electric screw 210 can drive the loading plate 200 to move up and down. When the transfer end moves out a sheet, the electric screw 210 can drive the loading plate 200 to move up by the height of a sheet, so that the transfer end reaches the topmost sheet after moving down the same distance each time, and the topmost sheet is transferred and adsorbed, thereby improving the stability during work.

[0030] In the transfer assembly, a transfer end that can move up and down is mainly formed to adsorb the sheet. There are various ways to transfer the sheet by the transfer end. It can be by clamping the sheet. In this embodiment, the transfer assembly includes a second lifting driving member 610, a lifting plate 620, and a vacuum chuck 630. The second lifting driving member 610 is disposed on the frame 100. The second lifting driving member 610 is drivingly connected to the lifting plate 620. The second lifting driving member 610 can drive the lifting plate 620 to move up and down. The vacuum chuck 630 is connected to the lifting plate 620. The vacuum chuck 630 is the transfer end. The second lifting driving member 610 can provide a driving force for the vacuum chuck 630 to move in the up and down direction. When the sheet needs to be transferred, the second lifting driving member drives the vacuum chuck 630 to move down to the sheet at the topmost side, and then drives the vacuum chuck 630 to move up to adsorb and separate the sheet at the topmost side.

[0031] After the transfer end separates the sheet upward, it can directly move up to another working station, or move horizontally to another working station. Specifically, the transfer assembly further includes a translation driving member 640 and a translation plate 650. The translation driving member 640 is connected to the frame 100. The translation driving member 640 is drivingly connected to the translation plate 650. The translation driving member 640 can drive the translation plate 650 to move in a direction close to or away from the loading plate 200. The second lifting driving member 610 is connected to the translation plate 650. A translation driving member 640 for driving the vacuum chuck 630 to move horizontally is further disposed on the frame 100. When the vacuum chuck 630 separates the sheet by moving it up, then the translation driving member 640 drives the translation plate 650 to move in a direction away from the loading plate 200 to transfer the sheet to the next working station, and then the translation driving member 640 drives the translation plate 650 to move in a direction close to the loading plate 200 to return to the original position.

[0032] In some embodiments, a detection sensor 320 is disposed on the backing plate 300. The detection sensor 320 is configured to detect whether there is a workpiece on the loading plate 200. In practical applications, the detection sensor 320 can use an optical fiber sensor, an infrared sensor, etc. Its detection point can be set at the position of the sheet at the uppermost side. When there is no workpiece on the loading plate 200, the detection point of the detection sensor 320 is not blocked by the workpiece, that is, the workpiece cannot be detected. During operation, the detection sensor 320 detects whether there is still a workpiece, that is, a sheet, on the loading plate 200, so as to facilitate the replenishment operation of the loading plate 200 by manual or mechanical means.

[0033] In some embodiments, limiting plates 220 are provided on both sides of the loading plate 200 in the width direction of the frame 100. The limiting plates 220 on both sides of the loading plate 200 can limit the stacked sheets, further improving the neatness of the stacked sheet discharging and preventing scattering.

[0034] In practical applications, the first lifting driving member, the second lifting driving member 610, and the translation driving member 640 are all used to provide the driving force for linear movement, and there are various structural forms, such as cylinders, hydraulic cylinders, or electric push rods, etc.

[0035] A hot bending machine includes the workpiece separating mechanism described above.

[0036] In this hot bending machine, by using the above workpiece separating mechanism to separate the sheets, the two mutually adsorbed sheets can be effectively separated, realizing the individual upward feeding of the stacked sheets, which is also applicable to the sheets with oil or electrostatic adsorption, and the working stability is higher.

[0037] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
