Description

Technical Field

[0001] The present invention relates to the technical field of mechanical handling equipment, and in particular to a cutting plate handling device. Background Art

[0002] In modern manufacturing, sheet metal parts are widely used in many fields such as construction, aerospace, automobile manufacturing, shipbuilding, etc. At the same time, various industries require sheet metal parts of various specifications, and the subsequent processing of the cut sheets requires frequent handling.

[0003] At present, there are two main ways to transport plates: manual transport and automatic transport. Manual transport mainly relies on direct manual operation. Workers use their hands or simple auxiliary tools, such as carts and ropes, to lift, move and place plates. This method is still widely used in small processing sites or scenarios where the handling accuracy is not high. Among the automatic transport methods, a truss structure transport system is common. The system is mainly composed of a truss frame, a mobile trolley, a grabbing device and other parts. The action process is: through a pre-set program, the mobile trolley moves horizontally and vertically along the truss track. After reaching the plate placement position, the grabbing device descends and uses suction cups, clamps and other tools to grab the plate, and then transports the plate to the designated location according to the established route.

[0004] However, these existing technologies have obvious defects. In the manual handling mode, the labor intensity of workers is high, especially when handling larger or heavier plates, the handling speed is slow and the production efficiency is low. Although the truss structure in the automatic handling mode can realize automated operation and improve handling efficiency, the equipment occupies a large area. For a production workshop with limited space, it will seriously compress the layout space of other production equipment and increase the difficulty and cost of site planning. Summary of the invention

[0005] The embodiment of the present application provides a cutting plate transport device, thereby solving the technical problem in the prior art that equipment for automatically transporting plates occupies a large space, and at the same time improving the transport efficiency of the plates.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a cutting plate transport device, including a chassis and a supporting mechanism that can be lifted and lowered relative to the chassis, a suction cup mechanism is installed at the bottom of the supporting mechanism, the supporting mechanism includes two parallel transverse supports, the ends of the two transverse supports are connected by a connecting frame, the connecting frame is hinged to the transverse supports, and a telescopic mechanism is also installed between the two transverse supports. When the length of the telescopic mechanism changes, the transverse support can rotate around the hinge with the connecting frame; linear guide rails are fixed to the bottom of the two transverse supports, and sliders are provided at the bottom of the linear guide rails. A bracket is installed below the slider, and the bracket is rotatably connected to the slider and fixed to the suction cup mechanism.

[0007] Since the telescopic mechanism is connected between the two lateral supports, and the connecting frame is hinged to the lateral supports, the lateral supports can be rotated around the hinges with the connecting frame by controlling the extension or shortening of the telescopic mechanism, thereby driving the support mechanism to swing. For example, when the telescopic mechanism is extended, the distance between the two lateral supports increases, pushing the lateral supports to rotate around the hinge points, and the support mechanism swings to one side, allowing the suction cup mechanism to move above the plate; when the telescopic mechanism is shortened, the distance between the two lateral supports decreases, pulling the lateral supports to rotate in the opposite direction around the hinge points, and the support mechanism swings in the opposite direction to transport the adsorbed plate to the designated position. Therefore, the device enables the support mechanism to transport the plate by swinging through the coordinated action of the telescopic mechanism and the lateral supports, without the need for a truss structure, thereby reducing the floor space and improving production efficiency.

[0008] As a further improvement of the above scheme, the lateral support includes a first lateral support and a second lateral support, and the two ends of the telescopic mechanism are rotatably connected to the first lateral support and the second lateral support respectively, and the connection between the telescopic mechanism and the first lateral support is close to the chassis, and the connection between the telescopic mechanism and the second lateral support is far away from the chassis; because the connection positions with the two lateral supports are one close and one far, when the telescopic mechanism is extended or shortened, the distance between the two lateral supports will change. This change in spacing will cause the lateral support to be subjected to forces in different directions, so that it can smoothly rotate around the hinge with the connecting frame, driving the support mechanism to swing. When transporting the plate, by controlling the change in the length of the telescopic mechanism, the support mechanism can flexibly swing to the top of the plate for suction operation; after the plate is sucked, the change in the length of the telescopic mechanism is controlled again, and the support mechanism can swing in the opposite direction to complete the transport of the plate.

[0009] As a further improvement of the above scheme, the telescopic mechanism includes a lead screw, one end of which is rotatably mounted with a support, the support is hinged to the first cross brace, the other end of the lead screw is connected to a sleeve, a nut is fixed in the sleeve, and the nut cooperates with the lead screw; the end of the sleeve away from the lead screw is hinged to the second cross brace; thus, by controlling the number of turns and direction of the lead screw, the moving distance of the nut relative to the lead screw can be adjusted, thereby controlling the extension or shortening of the telescopic mechanism. When actually transporting the plate, the rotation parameters of the lead screw can be accurately set according to different work requirements, so as to achieve precise adjustment of the length of the telescopic mechanism, ensure that the support mechanism swings to the correct position, ensure that the suction cup mechanism can accurately reach the suction position of the plate, and improve the precision and accuracy of the transportation.

[0010] As a further improvement of the above scheme, a driving motor is installed on the support, and a driving pulley is installed on the output end of the driving motor after passing through the support. The driving pulley is connected to a driven pulley through a belt, and the driven pulley is fixed to the end of the lead screw; the rotation speed of the driving motor can be adjusted according to actual work requirements; thereby, by controlling the rotation direction of the driving motor, the rotation direction of the lead screw can be controlled, thereby realizing the extension or shortening of the telescopic mechanism, and by changing the rotation speed of the driving motor, the rotation speed of the lead screw can be adjusted, thereby controlling the extension and retraction speed of the telescopic mechanism.

[0011] As a further improvement of the above scheme, the suction cup mechanism includes a crossbeam, a longitudinal beam I and a negative pressure suction cup I installed on the longitudinal beam I. The crossbeam is fixed to the bracket, and the longitudinal beam I is provided with multiple ones and arranged at intervals at the bottom of the crossbeam, and the negative pressure suction cup I is fixed to the longitudinal beam; multiple longitudinal beams I can make the negative pressure suction cup I distributed more evenly, apply adsorption force to the plate from multiple positions, and effectively avoid the plate from tilting or falling during transportation due to uneven adsorption force.

[0012] As a further improvement of the above scheme, a plurality of negative pressure suction cups I are fixed on each longitudinal beam I; thereby, the plurality of negative pressure suction cups I work together to further enhance the adsorption effect on the plate, thereby improving the safety and stability of the handling process.

[0013] As a further improvement of the above scheme, the suction cup mechanism also includes a spare suction cup group, which includes a fixed seat, one end of the fixed seat is fixed to the end of the beam, the other end of the fixed seat is hinged with a flip seat, the bottom of the flip seat is fixed with a longitudinal beam II, the bottom of the longitudinal beam II is fixed with a negative pressure suction cup II, and a cylinder is supported between the flip seat and the beam, the telescopic end of the cylinder is hinged to the top of the flip seat, and the cylinder body of the cylinder is installed at the end of the beam; in actual use, different plate sizes are also the same, for smaller plates, negative pressure suction cup I can be used for adsorption; and for larger plates, the flip seat can be controlled by the cylinder, so that the negative pressure suction cup II and the negative pressure suction cup I can be adsorbed at the same time. Therefore, by setting the spare suction cup group, the adsorption area and range of the suction cup mechanism can be expanded to ensure that it can provide sufficient adsorption force for different plates.

[0014] As a further improvement of the above scheme, the two sides of the bracket are respectively connected to the bottom of the two sliders through a rotating mechanism, and the rotating mechanism includes a sleeve, the lower end of the sleeve is fixed to the bracket, a rotating shaft is installed in the sleeve, and the upper end of the rotating shaft is fixed to the bottom of the slider; when the telescopic mechanism drives the two lateral supports to rotate around the hinge point of the connecting frame, the spacing change of the lateral supports will be transmitted to the bracket through the cooperation of the linear guide rail and the slider. Since the two sides of the bracket are connected to the slider through the rotating mechanism, the bracket can swing with the movement of the slider, satisfying the swing condition of the support mechanism, so that the suction cup mechanism can swing accordingly, and flexible handling of the plate is achieved.

[0015] As a further improvement of the above scheme, a bearing is also installed in the sleeve, the inner ring of the bearing is fixed to the rotating shaft, and the outer ring of the bearing is in contact with the inner wall of the sleeve; the setting of the bearing can reduce the friction resistance between the rotating shaft and the sleeve, so that the rotating shaft can rotate more smoothly in the sleeve, thereby improving the service life of the equipment, while also ensuring the flexibility and stability of the swing of the supporting mechanism.

[0016] As a further improvement of the above solution, a threaded hole is provided on the slider, and a screw is installed in the threaded hole. When the screw is tightened, one end of the screw can abut against one side of the linear guide rail. In actual handling work, it is sometimes necessary to fix the suction cup mechanism in a specific position to meet the handling requirements of different plates or adapt to a specific workflow. The slider and the linear guide rail can be locked by the screw, so that the bracket and the suction cup mechanism maintain a stable position, avoiding the plate positioning deviation caused by the accidental sliding of the slider during the handling process, and ensuring the accuracy and stability of the handling work.

[0017] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: 1. Since the telescopic mechanism is connected between the two lateral supports, and the connecting frame is hinged to the lateral supports, the lateral supports can be rotated around the hinges with the connecting frame by controlling the extension or shortening of the telescopic mechanism, thereby driving the support mechanism to swing. For example, when the telescopic mechanism is extended, the distance between the two lateral supports increases, pushing the lateral supports to rotate around the hinge points, and the support mechanism swings to one side, allowing the suction cup mechanism to move above the plate; when the telescopic mechanism is shortened, the distance between the two lateral supports decreases, pulling the lateral supports to rotate in the opposite direction around the hinge points, and the support mechanism swings in the opposite direction to transport the adsorbed plate to the designated position. Therefore, the device enables the support mechanism to transport the plate by swinging through the coordinated action of the telescopic mechanism and the lateral supports, without the need for a truss structure, thereby reducing the floor space and improving production efficiency.

[0018] 2. Since the telescopic mechanism includes a lead screw, the lead screw cooperates with the nut, and the nut is fixed to the sleeve, the moving distance of the nut relative to the lead screw can be adjusted by controlling the number of turns and direction of the lead screw, thereby controlling the extension or shortening of the telescopic mechanism. In this way, when actually transporting plates, the rotation parameters of the lead screw can be accurately set according to different work requirements, and the length of the telescopic mechanism can be accurately adjusted to ensure that the support mechanism swings to the correct position, thereby improving the precision and accuracy of transportation.

[0019] 3. Since the suction cup mechanism includes a spare suction cup group, the suction area and range of the suction cup mechanism can be expanded by setting the spare suction cup group to ensure that the suction cup mechanism can provide sufficient suction force for different plates.

[0020] 4. Since there is a threaded hole on the slider and a screw is installed in the threaded hole, the slider and the linear guide can be locked through the screw in the actual handling work, so that the bracket and the suction cup mechanism can maintain a stable position, avoiding the plate positioning deviation caused by accidental sliding of the slider during the handling process, and ensuring the accuracy and stability of the handling work.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] The present invention discloses a cutting plate transport device, such as Figure 1 As shown, it includes a chassis 1 and a support mechanism 2 that can be lifted and lowered relative to the chassis 1, and a suction cup mechanism 3 is installed at the bottom of the support mechanism 2. The support mechanism 2 includes two parallel transverse supports 201, the ends of the two transverse supports 201 are connected by a connecting frame 202, the connecting frame 202 is hinged to the transverse support 201, and a telescopic mechanism 5 is also installed between the two transverse supports 201. When the length of the telescopic mechanism 5 changes, the transverse support 201 can rotate around the hinge between it and the connecting frame 202; linear guides 6 are fixed to the bottom of the two transverse supports 201, and sliders 7 are matched at the bottom of the linear guides 6. A bracket 8 is installed below the slider 7, and the bracket 8 is rotatably connected to the slider 7 and fixed to the suction cup mechanism 3.

[0025] In this embodiment, two transverse supports 201 are arranged horizontally and parallel, and the two ends of the two transverse supports 201 are connected by a connecting frame 202, so that the support mechanism 2 forms a parallelogram structure. The two ends of the connecting frame 202 are respectively hinged to the ends of the two transverse supports 201, thereby providing a movable connection point for the rotation of the transverse supports 201. The telescopic mechanism 5 is installed between the two transverse supports 201. Specifically, the connection points of the telescopic mechanism 5 and the transverse support 201 are respectively the first connection point and the second connection point. The distance from the first connection point to the chassis 1 is L, and the distance from the second connection point to the chassis 1 is M, and L and M are not equal. Therefore, when the length of the telescopic mechanism 5 changes, it will push or pull the transverse support 201 to rotate around the hinge between it and the connecting frame 202. The linear guide 6 is fixed to the bottom of the transverse support 201 along the length direction of the transverse support 201. Slide grooves are provided on both sides of the linear guide 6. The slider 7 cooperates with the slide grooves on both sides of the linear guide 6, so that it can slide relative to the linear guide 6. The bracket 8 is installed below the slider 7 through a rotating mechanism and can rotate relative to the slider 7. The suction cup mechanism 3 is fixedly installed on the bracket 8 and moves with the movement of the bracket 8.

[0026] During actual operation, the height of the support mechanism 2 is adjusted according to the height of the table top of the cutting machine discharge port, so that it rises or falls relative to the chassis 1, and the suction cup mechanism 3 reaches a suitable height position. When it is necessary to transport the plate, the drive mechanism connected to the telescopic mechanism 5 is started to extend the telescopic mechanism 5. After the telescopic mechanism 5 is extended, it will push the two lateral supports 201 to swing horizontally relative to the chassis 1, for example, the shape of the support mechanism 2 changes from a rectangle to a parallelogram. When the support mechanism 2 swings above the plate, the suction cup mechanism 3 starts to work, and uses the negative pressure principle inside it to absorb the plate through the corresponding negative pressure suction cup. When the plate is stably adsorbed, the drive mechanism connected to the telescopic mechanism 5 is operated again to shorten the telescopic mechanism 5, which can drive the lateral support 201 to swing in the opposite direction and transport the plate to the specified position. Finally, the negative pressure of the suction cup mechanism 3 is released, the plate is put down, and a transport operation is completed.

[0027] In the above structure, the coordinated action of the telescopic mechanism 5 and the lateral support 201 enables the support mechanism 2 to transport the plate by swinging. Compared with the traditional manual transportation method, it significantly reduces the labor intensity of workers, improves production efficiency, and avoids work-related accidents caused by sharp plates during manual transportation; and there is no need to use a truss structure, which reduces the floor space.

[0028] In the connection structure between the telescopic mechanism 5 and the transverse support 201, the transverse support 201 includes a first transverse support 203 and a second transverse support 204, and the two ends of the telescopic mechanism 5 are rotatably connected to the first transverse support 203 and the second transverse support 204 respectively. The connection between the telescopic mechanism 5 and the first transverse support 203 is close to the chassis 1, and the connection between the telescopic mechanism 5 and the second transverse support 204 is far away from the chassis 1.

[0029] In this embodiment, if Figure 2 As shown, one end of the telescopic mechanism 5 is connected to the first cross brace 203 by a rotational connection (such as a connection structure such as a pin shaft), and the other end of the telescopic mechanism 5 is also connected to the second cross brace 204 by a rotational connection. Since the distances between the two connection points of the telescopic mechanism 5 and the chassis 1 are different, when the telescopic mechanism 5 is extended or shortened, the spacing between the two transverse supports 201 will change, so that the transverse supports 201 can rotate around the hinge with the connecting frame 202, driving the support mechanism 2 to swing. Therefore, in the process of transporting the plate, by controlling the change in the length of the telescopic mechanism 5, the support mechanism 2 can swing to the top of the plate for suction operation. After sucking the plate, the change in the length of the telescopic mechanism 5 is controlled again, and the support mechanism 2 can swing in the opposite direction to complete the plate transport. The entire operation process is flexible and efficient.

[0030] In the specific structure of the telescopic mechanism 5, the telescopic mechanism 5 includes a screw 501, one end of which is rotatably mounted with a support 502, the support 502 is hinged to the first cross brace 203, the other end of the screw 501 is connected to a sleeve 503, a nut is fixed inside the sleeve 503, and the nut cooperates with the screw 501; one end of the sleeve 503 away from the screw 501 is hinged to the second cross brace 204.

[0031] In this embodiment, if Figure 3 As shown, the support seat is provided with a circular hole for the lead screw 501 to pass through, and the end of the lead screw 501 is matched with the circular hole gap so that the lead screw 501 can rotate relative to the support 502. The support 502 is connected to the first cross brace 203 by a pin shaft to ensure the mobility of the connection. The lead screw 501 cooperates with the nut in the sleeve 503. When the driving mechanism applies a rotational force to the lead screw 501, the nut drives the sleeve 503 to move along the axial direction of the lead screw 501, thereby realizing the extension or shortening action of the telescopic mechanism 5. Therefore, in the actual process of transporting the plate, the length of the telescopic mechanism 5 can be accurately adjusted by accurately controlling the number of rotations and the direction of rotation of the lead screw 501. Since the connection mode of the telescopic mechanism 5 and the first cross brace 203 is a rotational connection, the length change of the telescopic mechanism 5 will drive the lateral support 201 to rotate around the hinge with the connecting frame 202. Therefore, by controlling the swing angle and position of the support mechanism 2, the suction cup mechanism 3 can accurately reach the suction position of the plate.

[0032] In the above structure, the transmission mode of the screw 501 and the nut enables the telescopic length of the telescopic mechanism 5 to be accurately controlled. By accurately adjusting the length of the telescopic mechanism 5, the support mechanism 2 can swing to the target position more stably and accurately, so that the suction cup mechanism 3 can accurately locate the suction position of the plate. The problem of plate suction failure caused by positioning deviation is effectively avoided, the precision and accuracy of handling are improved, and the reliability and stability of each handling operation are guaranteed. In other embodiments, the telescopic mechanism 5 can also use a hydraulic cylinder.

[0033] like Figure 3 As shown, in the specific structure of the telescopic mechanism 5, a driving motor 504 is installed on the support 502, and a driving pulley 505 is installed after the output end of the driving motor 504 passes through the support 502. The driving pulley 505 is connected to a driven pulley 507 through a belt 506, and the driven pulley 507 is fixed to the end of the screw 501.

[0034] In this embodiment, the driving motor 504 is fixedly mounted on the support 502, and its output shaft passes through the plate surface of the support 502 and is fixed to the driving pulley 505 by a key connection. The driving pulley 505 and the driven pulley 507 are driven by a belt 506, and the driven pulley 507 is fixed to the end of the lead screw 501 by a key connection. Among them, the rotation speed of the driving motor 504 can be adjusted according to actual work requirements. By controlling the rotation direction of the driving motor 504, the rotation direction of the lead screw 501 can be controlled, thereby realizing the extension or shortening of the telescopic mechanism 5; at the same time, changing the rotation speed of the driving motor 504 can conveniently adjust the rotation speed of the lead screw 501, thereby realizing the control of the telescopic speed of the telescopic mechanism 5. Therefore, when carrying plates of different weights and sizes, the rotation speed and rotation direction of the driving motor 504 can be adjusted according to actual conditions to ensure that the support mechanism 2 can swing smoothly to a suitable position.

[0035] In the above structure, the transmission system composed of the drive motor 504, the active pulley 505, the belt 506 and the driven pulley 507 provides a power source for the telescopic mechanism 5, and by controlling the direction and speed of the drive motor 504, the telescopic speed and direction of the telescopic mechanism 5 can be flexibly controlled, thereby enhancing the practicability and operability of the equipment.

[0036] The suction cup mechanism 3 includes a crossbeam 301, a longitudinal beam I 302 and a negative pressure suction cup I 303 installed on the longitudinal beam I 302. The crossbeam 301 is fixed to the bracket 8. The longitudinal beam I 302 is provided with a plurality of negative pressure suction cups I 303 arranged at intervals at the bottom of the crossbeam 301. The negative pressure suction cup I 303 is fixed to the longitudinal beam.

[0037] In this embodiment, if Figure 4As shown, the crossbeam 301 is a long strip structure. Multiple longitudinal beams Ⅰ302 are installed in parallel and at intervals at the bottom of the crossbeam 301, and each longitudinal beam Ⅰ302 is fixed with a negative pressure suction cup Ⅰ303. Since plates of different specifications differ in size and shape, the design of multiple longitudinal beams Ⅰ302 and multiple negative pressure suction cups Ⅰ303 enables the suction cup mechanism 3 to adjust the number and position of the negative pressure suction cups Ⅰ303 involved in the adsorption according to the size of the plate. When transporting smaller plates, the negative pressure suction cups Ⅰ303 on some longitudinal beams Ⅰ302 can be activated; when transporting larger plates, more negative pressure suction cups Ⅰ303 on longitudinal beams Ⅰ302 are activated to ensure sufficient adsorption force and ensure the stability of the plate during transportation.

[0038] Specifically, a plurality of negative pressure suction cups Ⅰ303 are fixed on each longitudinal beam Ⅰ302. The negative pressure suction cups Ⅰ303 are arranged at equal intervals on the longitudinal beam. This arrangement can make the longitudinal beam Ⅰ302 adsorb the plate more evenly, thereby effectively avoiding the plate from tilting or falling during transportation due to uneven adsorption force. Moreover, the coordinated work of multiple negative pressure suction cups Ⅰ303 can enhance the adsorption effect of the plate, further improving the safety and stability of transportation.

[0039] In addition, the suction cup mechanism 3 also includes a spare suction cup group 4, which includes a fixed seat 401, one end of the fixed seat 401 is fixed to the end of the beam 301, and the other end of the fixed seat 401 is hinged with a flip seat 402, the bottom of the flip seat 402 is fixed with a longitudinal beam II 403, and the bottom of the longitudinal beam II 403 is fixed with a negative pressure suction cup II 404, and a cylinder 405 is also supported between the flip seat 402 and the beam 301, the telescopic end of the cylinder 405 is hinged to the top of the flip seat 402, and the cylinder body of the cylinder 405 is installed at the end of the beam 301.

[0040] In this embodiment, if Figure 4 , Figure 5As shown, the rear end of the fixed seat 401 is fixed to the end of the crossbeam 301 by welding or bolt connection. The rear end of the flip seat 402 is hinged to the bottom of the front end of the fixed seat 401 through a pin, so that the flip seat 402 can rotate around the hinge point between it and the fixed seat 401. The longitudinal beam II 403 is fixed to the bottom of one end of the flip seat 402 by welding, and a plurality of negative pressure suction cups II 404 are provided and fixed at equal intervals at the bottom of the longitudinal beam II 403. The top of the flip seat 402 is provided with a pin, and the telescopic end of the cylinder 405 is provided with a hinge hole, which is hinged to the pin at the top of the flip seat 402; the cylinder body of the cylinder 405 is hinged to the end of the crossbeam 301. When transporting a smaller plate, the cylinder 405 contracts, driving the flip seat 402 to flip upward, so that the negative pressure suction cup II 404 is away from the plate, and only the negative pressure suction cup I 303 is used for adsorption; when transporting a larger plate, the cylinder 405 extends, pushing the flip seat 402 to flip downward, so that the negative pressure suction cup II 404 and the negative pressure suction cup I 303 adsorb the plate at the same time to ensure sufficient adsorption force. Therefore, the setting of the spare suction cup group 4 can increase the adsorption range of the suction cup mechanism 3, can meet the transport needs of plates of various specifications, and expand the application range of the equipment.

[0041] In the structure in which the bracket 8 is connected to the slider 7, the two sides of the bracket 8 are connected to the bottom of the two sliders 7 through a rotating mechanism. The rotating mechanism includes a sleeve 9, the lower end of the sleeve 9 is fixed to the bracket 8, a rotating shaft 10 is installed in the sleeve 9, and the upper end of the rotating shaft 10 is fixed to the bottom of the slider 7.

[0042] In this embodiment, if Figure 4 , Figure 6 As shown, two rotating mechanisms are provided, and the two rotating mechanisms are installed at symmetrical positions on both sides of the bracket 8. The sleeve 9 is a cylindrical structure, and its lower end is fixed to the bracket 8 by welding or other means. The rotating shaft 10 is vertically installed in the sleeve 9, and its upper end is fixed to the bottom of the slider 7 by bolt connection or welding or other means. When the telescopic mechanism 5 drives the two lateral supports 201 to rotate around the hinge point of the connecting frame 202, the spacing change of the lateral supports 201 will be transmitted to the bracket 8 through the cooperation of the linear guide 6 and the slider 7. Since the two sides of the bracket 8 are connected to the bottom of the two sliders 7 through the rotating mechanism, the swing condition of the support mechanism 2 can be met, so that the suction cup mechanism 3 can swing with the support mechanism 2.

[0043] In the above structure, the setting of the rotating mechanism ensures that the bracket 8 can swing with the movement of the slider 7 and the lateral support 201, so that the suction cup mechanism 3 can better adapt to the movement of the support mechanism 2, thereby improving the overall movement coordination and handling accuracy of the equipment.

[0044] Specifically, a bearing 11 is installed in the sleeve 9, the inner ring of the bearing 11 is fixed to the rotating shaft 10, and the outer ring of the bearing 11 is in contact with the inner wall of the sleeve 9. Figure 6 As shown, the bearing 11 is installed in the sleeve 9, and its inner diameter matches the rotating shaft 10, and its outer diameter matches the inner wall of the sleeve 9. The inner ring of the bearing 11 is fixed to the rotating shaft 10 by interference fit or key connection, and the outer ring is in close contact with the inner wall of the sleeve 9. The arrangement of the bearing 11 can reduce the friction resistance between the rotating shaft 10 and the sleeve 9, so that the rotating shaft 10 rotates more smoothly in the sleeve 9, reducing the wear during the operation of the equipment, and increasing the service life of the equipment. At the same time, it also ensures the flexibility and stability of the swing of the support mechanism 2.

[0045] In addition, the slider 7 is provided with a threaded hole, in which a screw rod 12 is installed. When the screw rod 12 is tightened, one end of the screw rod 12 can abut against one side of the linear guide rail 6. Figure 6 As shown, the threaded hole on the slide block 7 is opened in a direction perpendicular to the linear guide rail 6, and the screw rod 12 is screwed into the threaded hole.

[0046] In actual handling work, it is sometimes necessary to fix the suction cup mechanism 3 at a specific position to meet the handling requirements of different plates or adapt to a specific work process. Since the slider 7 is provided with a threaded hole, and the screw 12 is installed in the threaded hole, the slider 7 and the linear guide 6 can be locked by the screw 12, so that the bracket 8 and the suction cup mechanism 3 maintain a stable position, avoiding the plate positioning deviation caused by the accidental sliding of the slider 7 during the handling process, and ensuring the accuracy and stability of the handling work.

[0047] When the cutting plate handling device is actually used, firstly, according to the height of the table top of the cutting machine outlet, operate the support mechanism 2 to adjust the lifting relative to the chassis 1, so that the suction cup mechanism 3 reaches the appropriate height. Then, control the telescopic mechanism 5 to work, and extend or shorten the telescopic mechanism 5 through the cooperation of the lead screw 501 and the nut. Since the two ends of the telescopic mechanism 5 are at different rotational connection positions with the lateral support 201, the change in its length will drive the lateral support 201 to rotate around the hinge with the connecting frame 202, so that the support mechanism 2 swings above the plate. At this time, the suction cup mechanism 3 is started, and the negative pressure suction cup Ⅰ303 starts to work to absorb the plate. After the plate is firmly adsorbed, adjust the telescopic mechanism 5 again to make the support mechanism 2 swing in the opposite direction, and transport the plate to the specified position. Finally, close the negative pressure suction cup Ⅰ303 and put down the plate, completing a handling operation.

[0048] Compared with manual handling, this device uses a mechanical structure to carry the plates, so workers do not need to directly touch the sharp cutting plates, avoiding the occurrence of industrial accidents; at the same time, it greatly reduces the labor intensity of workers and improves production efficiency. Compared with the truss handling method, this device has a compact structure, small space occupation, and relatively simple installation and commissioning.
