Description

Technical Field

[0001] The present invention relates to the technical field of hot pressing machinery, and more specifically, to a high-rise press plate clamping and moving robot for simultaneously pushing multiple plates into a hot pressing space or pushing them out of the hot pressing space. Background Art

[0002] As is well known, during the processing of wood composite boards, adhesives need to be filled between each layer of boards and then a pressing process is carried out. In the existing process, a simple auxiliary cold pressing die is usually used to perform individual pressing processes on woodworking composite boards. The auxiliary cold pressing die is composed of a lower pressing plate, an upper pressing plate, and a clamping device. During pressing, an operator places the veneer plywood to be pressed on the lower pressing plate, then covers the upper pressing plate, and the clamping device clamps around the lower pressing plate and the upper pressing plate for cold pressing at normal temperature. The substantial deficiency of this structure is that the operator can only press one plywood board at a time, which is not only time-consuming and laborious, with extremely low production efficiency, but also the pressing thickness is uneven, and there are even air bubbles in some of the pressed plywood boards, resulting in poor pressing quality.

[0003] To solve the above technical problems, the applicant of the present invention invented a device capable of simultaneously pressing several plywood boards. Although it can perform hot pressing treatment on several plywood boards simultaneously, making the pressed thickness of the plywood boards uniform and the pressing quality high, after hot pressing, it is still necessary to manually remove the hot-pressed plywood boards from the hot pressing cavity one by one, resulting in troublesome operation, low work efficiency, and high labor intensity. Summary of the Invention

[0004] In order to solve the above-mentioned substantial deficiencies of the prior art, the present invention provides a high-rise press plate clamping and moving robot with novel structure, convenient operation, high work efficiency, low labor intensity, and high processing quality.

The moving trolley (15) is connected to the longitudinal slide rail (14) in a rolling manner through rollers. A moving oil cylinder (16) is provided on the frame of the moving trolley (15). The lower end of the moving trolley (15) is fixedly connected to the upper ends of two parallel moving longitudinal plate frames (17). The end of the telescopic rod of the moving oil cylinder (16) is hinged to the upper beam (1-2) fixedly connected to the longitudinal slide rail (14), so as to drive the moving longitudinal plate frame (17) to move along the longitudinal slide rail (14) through the moving oil cylinder (16). The two parallel moving longitudinal plate frames (17) are connected at intervals by at least two clamping plate hinge shafts (27). In front of the two parallel moving plate frames, there are two brackets (19) parallel to the moving plate frames. The brackets (19) are provided with right connecting shafts (29) that match the number of left connecting shafts (28) on the moving longitudinal plate frames (17). The front end of the brackets (19) is longitudinally and fixedly provided with a unit support plate frame (21). The front end of the unit support plate frame (21) is fixedly connected to the unit fixed clamping plate (20). The rear parts on both sides of the unit fixed clamping plate (20) are provided with backing plates (24). The rear end of the backing plates (24) is fixedly connected to the brackets (19). One end of the rotating arm (25) is connected to the left connecting shaft (28) through a bearing, and the other end is connected to the right connecting shaft (29) through a bearing.

[0007] The unit movable clamping plate fixing frame (23) is located in the middle of the two brackets (19). At least two clamping plate hinge shafts (27) are provided at intervals at the rear end of the unit movable clamping plate fixing frame (23) and are fixedly connected to the clamping plate hinge shafts (27). The front end is fixedly provided with a unit movable clamping plate (22) that cooperates with the unit fixed clamping plate (20) for clamping. The upper end is hinged to the moving trolley (15) through the clamping oil cylinder (18). The unit movable clamping plate (22) is located below the unit fixed clamping plate (20). The unit fixed clamping plate (20) and the unit movable clamping plate (22) form a unit clamping manipulator.

[0008] One end of the connecting rotating arm (26) is connected to the left connecting shaft (28) through a bearing, and the other end is connected to the clamping plate hinge shaft (27) through a bearing.

[0009] The moving oil cylinder (16) and the clamping oil cylinder (18) are respectively connected to the control system.

[0010] In the present invention, a clamping force enhancing device (30) may be provided between the clamping oil cylinder (18) and the frame of the moving trolley (15). The device includes a screw rod (30-1), a locking nut (30-2), a positioning nut (30-3), a guiding plate (30-4), a lower positioning plate (30-5), and a positioning block (30-6). The middle part of the screw rod (30-1) is a smooth rod section, the upper part is provided with an upper screw rod section, and the lower part is provided with a lower screw rod section. The upper part of the screw rod (30-1) passes through the frame via the upper screw rod section and is fixedly connected to the frame in contact with the locking nut (30-2). The smooth rod of the screw rod (30-1) can axially move through the guiding hole provided on the guiding plate (30-4), and then the lower screw rod section at its lower part is threadedly connected to the positioning nut (30-3) and is connected in contact with the guiding plate (30-4) via the positioning nut (30-3).

The lower positioning plate (30-5) is fixed to the lower rear end of the unit movable clamping plate fixing frame (23), and the positioning block (30-6) is fixed to the lower front end of the moving longitudinal plate frame (17). The lower end of the lower positioning plate (30-5) corresponds to the positioning block (30-6). When clamping a plate, the control system instructs the clamping oil cylinder (18) to act. The clamping oil cylinder (18) drives the unit movable clamping plate fixing frame (23) to move downward, so that the opening angle between the unit movable clamping plate (22) and the unit fixed clamping plate (20) is maximized. When the lower positioning plate (30-5) at the lower part of the unit movable clamping plate fixing frame (23) contacts the positioning block (30-6), since the telescopic rod of the clamping oil cylinder (18) continues to extend downward, at this time, the clamping oil cylinder (18) is driven by the telescopic rod to vertically rise in the reverse direction along the smooth rod section of the screw rod (30-1) via the guiding plate (30-4), thereby driving the unit movable clamping plate fixing frame (23) and the unit movable clamping plate (22) at the front end of the unit movable clamping plate fixing frame (23) to move upward to clamp the glued plate with the unit fixed clamping plate (20), significantly increasing the clamping force of the glued plate.

[0011] A rubber pad (31) is installed on the unit movable clamping plate (22) of the present invention to avoid scratching the surface of the hot-pressed glued plate and ensure the quality of the hot-pressed glued plate.

The end of the telescopic rod of the moving oil cylinder (16) is hinged to the upper beam (1-2) fixedly connected to the longitudinal slide rail (14), so as to drive the moving longitudinal plate frame (17) to move along the longitudinal slide rail (14) through the moving oil cylinder (16). The two parallel moving longitudinal plate frames (17) are at least connected at intervals through two left connecting shafts (28). In front of the two parallel moving longitudinal plate frames (17), there are two brackets (19) parallel to the moving longitudinal plate frames. The brackets (19) are provided with right connecting shafts (29) matching the number of left connecting shafts (28) on the moving longitudinal plate frames (17). The front end of the brackets (19) is longitudinally and fixedly provided with a unit support plate frame (21). The front end of the unit support plate frame (21) is fixedly connected to the unit fixed clamping plate (20). The rear parts on both sides of the unit fixed clamping plate (20) are provided with backing plates (24). The rear ends of the backing plates (24) are fixedly connected to the brackets (19). One end of the rotating arm (25) is connected to the left connecting shaft (28) through a bearing, and the other end is connected to the right connecting shaft (29) through a bearing,

[0024] The unit movable clamping plate fixing frame (23) is located in the middle of the two brackets (19). At least two clamping plate hinge shafts (27) are provided at intervals at the rear end of the unit movable clamping plate fixing frame (23) and are fixedly connected to the clamping plate hinge shafts (27). The front end is fixedly provided with a unit movable clamping plate (22) that cooperates with the unit fixed clamping plate (20) for clamping. The upper end is hinged to the moving trolley (15) through the clamping oil cylinder (18). The unit movable clamping plate (22) is located below the unit fixed clamping plate (20). The unit fixed clamping plate (20) and the unit movable clamping plate (22) form a unit clamping manipulator. One end of the connecting rotating arm (26) is connected to the left connecting shaft (28) through a bearing, and the other end is connected to the clamping plate hinge shaft (27) through a bearing. The moving oil cylinder (16) and the clamping oil cylinder (18) are respectively connected to the control system. The control system adopts a PLC control system.

[0025] As shown in the appendix Figure 1 , 2, as shown in FIGS. 5, a clamping force enhancing device (30) may be provided between the clamping oil cylinder (18) and the frame of the moving trolley (15) in the present invention. The clamping force enhancing device (30) includes a screw rod (30-1), a locking nut (30-2), a positioning nut (30-3), a guide plate (30-4), a lower positioning plate (30-5) and a positioning block (30-6). The middle part of the screw rod (30-1) is a smooth rod section, the upper part is provided with an upper screw rod section, and the lower part is provided with a lower screw rod section. The upper part of the screw rod (30-1) passes through the frame through the upper screw rod section and is fixedly connected with the frame by the locking nut (30-2). The smooth rod of the screw rod (30-1) can axially move through the guide hole provided on the guide plate (30-4), and then the lower screw rod section at its lower part is threadedly connected with the positioning nut (30-3) and is in contact connection with the guide plate (30-4) through the positioning nut (30-3). The lower end of the guide plate (30-4) is connected with the clamping oil cylinder (18). The lower positioning plate (30-5) is fixed at the lower rear end of the unit movable clamping plate fixing frame (23), and the positioning block (30-6) is fixed at the lower front end of the moving longitudinal plate frame (17). The lower end of the lower positioning plate (30-5) corresponds to the positioning block (30-6). When clamping a plate, the control system commands the clamping oil cylinder (18) to act. The clamping oil cylinder (18) drives the unit movable clamping plate fixing frame (23) to move downward, so that the opening angle between the unit movable clamping plate (22) and the unit fixed clamping plate (20) is the largest. When the lower positioning plate (30-5) at the lower part of the unit movable clamping plate fixing frame (23) contacts the positioning block (30-6), since the telescopic rod of the clamping oil cylinder (18) continues to extend downward, at this time, the clamping oil cylinder (18) is driven by the telescopic rod to reversely and vertically rise along the smooth rod section of the screw rod (30-1) through the guide plate (30-4), thereby driving the unit movable clamping plate fixing frame (23) and the unit movable clamping plate (22) at the front end of the unit movable clamping plate fixing frame (23) to move upward to clamp the glued plate with the unit fixed clamping plate (20), significantly increasing the clamping force of the glued plate.

[0026] As shown in the attached Figure 7 , 8 FIGS., a rubber pad (31) is installed on the unit movable clamping plate (22) of the present invention to avoid scratching the surface of the hot-pressed glued plate, ensuring the quality of the hot-pressed glued plate. At the same time, it can also play a role in increasing the friction force when clamping the plate.

[0027] The front end of the unit fixed clamping plate of the present invention is inclined downward along the horizontal plane to further increase the clamping force.

[0028] The unit movable clamping plate of the present invention is inclined downward relative to the horizontal plane, and the inclination degree is smaller than that of the unit fixed clamping plate, so as to further increase the clamping force.

[0029] When the hot-pressed sheet is to be taken out, the control system instructs the moving cylinder (16) to move, and the moving cylinder (16) drives the moving trolley (15) to move along the longitudinal slide rail (14) toward the high-layer press. When the unit clamping manipulator at the front end of the moving longitudinal plate frame (17) at the lower end of the moving trolley (15) leans against the plywood, the outer end of the plywood hits the support plate (24). After receiving the in-position information, the control system instructs the moving cylinder (16) to stop and instructs the clamping cylinder (18) to move. The clamping cylinder (18) drives the unit movable clamp plate fixing frame (23) to move downward, so that the opening angle of the unit movable clamp plate (22) and the unit fixed clamp plate (20) is maximized. When the lower positioning plate (30-5) at the lower part of the unit movable splint fixing frame (23) contacts the positioning block (30-6), the telescopic rod of the clamping oil cylinder (18) continues to extend downward. At this time, the clamping oil cylinder (18) is driven by the telescopic rod to rise vertically in the opposite direction along the light rod section of the screw rod (30-1) through the guide plate (30-4), thereby driving the unit movable splint fixing frame (23) and the unit movable splint (22) at the front end of the unit movable splint fixing frame (23) to move upward to clamp the plywood with the unit fixed splint (20), and the control system then instructs the moving oil cylinder (16) to move in the opposite direction, so that the unit clamping manipulator clamps and moves the plywood out.

[0030] Similarly, the present invention can also use the above-mentioned action to clamp the plywood to be hot-pressed and push the multi-layer plywood to be hot-pressed into the hot-pressing space of the high-layer press for hot-pressing treatment.

[0031] The present invention has the advantages of novel structure, convenient operation, high working efficiency, low labor intensity, high processing quality, etc. due to the adoption of the above structure.
