[0006] Preferably, the winding device includes a winding motor installed on the bottom side of the middle part of the support plate, a winding roller is arranged on the upper side of the middle part of the support plate, and a power output end of the winding motor is connected to the winding roller.

[0007] Preferably, the suction cup assembly includes a mounting seat, an air pipe is slidably arranged up and down through the mounting seat, a suction cup is arranged at the bottom end of the air pipe, a buffer spring is sleeved on the air pipe between the suction cup and the mounting seat, the top of the buffer spring is fixedly connected to the mounting seat, and the bottom of the buffer spring is fixedly connected to the top of the suction cup.

[0008] Preferably, limit blocks are provided at both ends of the longitudinal rod.

[0009] Preferably, the elastic force of the scaling spring on the transverse rod is the same as the sum of the elastic forces of the plurality of scaling springs on the longitudinal rod.

[0010] Preferably, a visual sensor is provided at the bottom of the support plate.

[0011] Preferably, the limit blocks are detachably mounted on both ends of the longitudinal rod, and both ends of the second traction rope are detachably connected to the fixing plate and the mounting seat, respectively.

[0012] Preferably, the transverse rod and the longitudinal rod are both square, and the mounting seat is provided with through grooves adapted to the transverse rod and the longitudinal rod, respectively.

[0013] The beneficial effects of the embodiments of the present invention are:

[0014] 1. The device can reel in the first traction rope by starting the reeling device. When the first traction rope is reeled in, the sliding seat is driven to move toward the reeling device on the support plate. Since the suction cup assembly on the transverse rod is slidably arranged, and the suction cup assembly is connected to the fixed plate at the end of the support plate by the second traction rope bypassing the guide wheel on the sliding seat, when the first traction rope is reeled in, the suction cup assembly on the transverse rod can be driven to move in the direction of the moving seat. When the suction cup assembly approaches the sliding seat, the suction cup assemblies at both ends of the longitudinal rod will also approach each other. Since a plurality of suction cup assemblies are arranged on the longitudinal rod, and a scaling spring sleeved on the longitudinal rod is arranged between the plurality of suction cup assemblies, the plurality of suction cup assemblies on the longitudinal rod can be retracted according to a certain proportion. Since the suction cup assembly on the transverse rod approaches the sliding seat, the entire longitudinal rod and the plurality of self-disc assemblies on the longitudinal rod can be driven to approach the support plate, so that the distance between the plurality of suction cup assemblies can be retracted in the same proportion, so as to adapt to the sheet materials of the same proportion but smaller size, improve the adaptability of the device, realize automatic and precise adjustment work, and ensure the stability of the end picker when working.

[0015] 2. The device releases the first traction rope on the winding device, and the scaling spring mounted on the transverse rod will perform a reset operation, driving the suction cup assembly on the transverse rod away from the moving seat. When the suction cup assembly is away from the moving seat, the elastic force of the scaling spring of the second traction rope on the transverse rod and the second traction rope parallel to the transverse rod become longer, which can drive the moving seat to move toward the two ends of the support plate. The spacing between the multiple suction cup assemblies on the longitudinal rod becomes larger under the action of the scaling spring, thereby achieving proportional enlargement of the end picker to adapt to sheets of the same proportion but larger size, realizing the automatic adjustment function of the end picker to adapt to sheets of the same proportion but different sizes, reducing the workload of the operator, and ensuring the stability of the end picker.

[0016] 3. This device is provided with a buffer spring. When the suction cup abuts against the sheet material, the buffer spring is in a stretched state. When the suction cup is vacuumed through the air pipe, the suction cup completely abuts against the sheet material. During the contraction of the suction cup, the buffer spring resets and drives the air pipe to move toward the sheet material, thereby ensuring the adsorption of the suction cup and the sheet material and ensuring stability during the subsequent movement of the sheet material.

[0017] 4. Through the detachable installation limit block and the second traction rope, the device can remove multiple suction cup assemblies from the transverse rod or the longitudinal rod, which is convenient for replacing a single damaged suction cup assembly and avoids removing the entire end picker for repair, thereby ensuring the working efficiency of the device and repairing or replacing a single suction cup assembly, which can reduce the cost of repair or replacement.

[0018] 5. As the device is provided with a visual sensor, when the end picker is located directly above the sheet material to be transferred, the second rotary motor can be used to drive the end picker to rotate to adapt to the length and width of the sheet material, and then the winding device can be used to drive multiple suction cup assemblies to scale in proportion to adapt to sheets of the same proportion but different sizes. Through program control, the degree of automation of the device is improved, and no operator intervention is required, thereby reducing the operator's labor intensity and the operator's use cost.

[0019] 6. After the end picker of the device rotates following the first rotating motor, in order to prevent the length direction of the sheet material adsorbed by the end picker from not coinciding with the length direction of the conveyor belt, resulting in the conveyor belt being unable to effectively transport the sheet material, the second rotating motor drives the end picker to rotate 90° forward or reversely, so that the length direction of the sheet material coincides with the length of the conveyor belt in the opposite direction, which facilitates the conveyor belt to effectively transport the sheet material, further improving the practicality of the device and ensuring that the device can achieve the moving effect for sheets of the same proportion but different sizes.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] A high-speed stamping line feed end picker, such as Figure 1-Figure 5As shown, it includes two door-shaped support frames 1, a movable track 2 is arranged between the two support frames 1, a slide rail 3 is arranged on one side of the movable track 2, a movable seat 4 is installed on the slide rail 3 through a slider 5, a cylinder 6 is arranged on the movable seat 4, a first rotating motor 7 is installed at the power output end of the cylinder 6, a support arm 8 is installed on the side of the first rotating motor 7, a second rotating motor 9 is arranged on the top of the end of the support arm 8 away from the movable seat 4, the power output end of the second rotating motor 9 is arranged through the support arm 8, a mounting frame 10 is arranged at the power output end of the second rotating motor 9, and an adjustable end picker is arranged at the bottom of the mounting frame 10; the end picker includes a support plate 11 connected to the mounting frame 10, a winding device is arranged in the middle of the support plate 11, and the Sliding seats 15 are provided at both ends of the support plate 11, and transverse rods 17 are provided at the opposite ends of the sliding seat 15. A suction cup assembly is slidably provided on the transverse rod 17, and a longitudinal rod 18 is slidably provided between the suction cup assemblies on the two transverse rods 17 on the same side. Multiple suction cup assemblies are slidably provided on the longitudinal rod 18, and a zoom spring 20 is sleeved on the transverse rod 17. The zoom spring 20 is located between the suction cup assembly and the sliding seat 15, and a zoom spring 20 is sleeved between the multiple suction cup assemblies on the longitudinal rod 18. Fixed plates 16 are provided at both ends of the support plate 11, and a guide wheel 19 is provided on the upper end of the sliding seat 15. The suction cup assembly is connected to the fixed plate 16 by bypassing the guide wheel 19 through a second traction rope 26, and the sliding seat 15 is connected to the winding device through a first traction rope 14.

[0030] For rectangular sheets of the same proportion but different sizes, when the processed sheets need to be moved, the moving seat 4 of the device is moved by the cooperation of the slide rail 3 and the slider 5, and then the first rotating motor 7 is used to drive the support arm 8 to rotate the angle to ensure that the end picker is located directly above the sheet. According to the length and width direction of the sheet, the second rotating motor 9 drives the end picker to rotate to ensure that the end picker can adapt to the length and width direction of the sheet. The cylinder 6 works to drive the support arm 8 to descend, so that multiple suction cup assemblies on the end picker can abut against the sheet. The suction cup assembly is vacuumed through the air pipe 23 to ensure the stability of the suction of the suction cup assembly and the sheet. The cylinder 6 works to drive the support arm 8 to rise, so that the end picker moves the sheet up, and then the moving seat 4 moves on the moving rail 2, and the first rotating motor 7 drives the support arm 8 to rotate, so that the sheet is moved to the position where the sheet needs to be placed, and then the support arm 8 is driven down by the work of the cylinder 6 to place the sheet at the designated position. The sheet is transferred by releasing the suction cup assembly.

[0031] When the sheet material to be moved is of the same proportion as the previously transferred sheet material but is smaller in size, in order to prevent the suction cup assembly of the end picker from being unable to adsorb the sheet material, the first traction rope 14 can be reeled in by starting the reeling device. When the first traction rope 14 is reeled in, the sliding seat 15 is driven to move toward the reeling device on the support plate 11. Since the suction cup assembly on the transverse rod 17 is slidably arranged, and the suction cup assembly bypasses the guide wheel 19 on the sliding seat 15 through the second traction rope 26 and is connected to the fixed plate 16 at the end of the support plate 11, when the first traction rope 14 is reeled in, the suction cup assembly on the transverse rod 17 can be driven to move toward the moving seat 4. When the suction cup assembly approaches the sliding seat 15, the longitudinal The suction cup assemblies at both ends of the rod 18 will also approach each other. Since a plurality of suction cup assemblies are arranged on the longitudinal rod 18, and a scaling spring 20 sleeved on the longitudinal rod 18 is arranged between the plurality of suction cup assemblies, the plurality of suction cup assemblies on the longitudinal rod 18 can be retracted in a certain proportion. Since the suction cup assembly on the transverse rod 17 approaches the sliding seat 15, the entire longitudinal rod 18 and the plurality of self-disc assemblies on the longitudinal rod 18 can be driven to approach the direction of the supporting plate 11, and the distance between the plurality of suction cup assemblies can be retracted in the same proportion, so as to adapt to the sheet materials of the same proportion but smaller size, improve the adaptability of the device, realize automatic and precise adjustment work, and ensure the stability of the end picker when working;

[0032] Conversely, when it is necessary to increase the spacing between the suction cup assemblies, the first traction rope 14 on the winding device is released, and the scaling spring 20 mounted on the transverse rod 17 will perform a reset operation, driving the suction cup assembly on the transverse rod 17 away from the moving seat 4. When the suction cup assembly is away from the moving seat 4, the elastic force of the scaling spring 20 of the second traction rope 26 on the transverse rod 17 and the second traction rope 26 parallel to the transverse rod 17 become longer, which can drive the moving seat 4 to move toward the two ends of the support plate 11. The spacing between the multiple suction cup assemblies on the longitudinal rod 18 is increased under the action of the scaling spring 20, thereby achieving a proportional enlargement of the end picker to adapt to sheets of the same proportion but larger size, realizing the automatic adjustment function of the end picker to adapt to sheets of the same proportion but different sizes, reducing the workload of the operator, and ensuring the stability of the end picker.

[0033] The winding device includes a winding motor 12 installed on the bottom side of the middle part of the support plate 11 , a winding roller 13 is arranged on the upper side of the middle part of the support plate 11 , and a power output end of the winding motor 12 is connected to the winding roller 13 .

[0034] The winding motor 12 is controlled by a controller to rotate forward and reverse, and can drive the winding roller 13 to rotate forward and reverse, so that the winding roller 13 can wind the first traction rope 14 on the winding roller 13, or release it from the winding roller 13, so as to adjust the spacing between multiple suction cup assemblies on the end picker.

[0035] The suction cup assembly includes a mounting seat 21, an air pipe 23 is slidably arranged up and down through the mounting seat 21, a suction cup 22 is arranged at the bottom end of the air pipe 23, a buffer spring 24 is sleeved on the air pipe 23 between the suction cup 22 and the mounting seat 21, the top of the buffer spring 24 is fixedly connected to the mounting seat 21, and the bottom of the buffer spring 24 is fixedly connected to the top of the suction cup 22.

[0036] The air pipe 23 is slidably arranged in the mounting seat 21. When the suction cup 22 abuts against the sheet material, damage to the suction cup assembly is avoided. By arranging a buffer spring 24, when the suction cup 22 abuts against the sheet material, the buffer spring 24 is in a stretched state. When the suction cup 22 is vacuumed through the air pipe 23, the suction cup 22 completely abuts against the sheet material. During the contraction of the suction cup 22, the buffer spring 24 is reset, driving the air pipe 23 to move toward the sheet material, thereby ensuring the adsorption of the suction cup 22 and the sheet material, and ensuring stability during the subsequent movement of the sheet material.

[0037] Limiting blocks 25 are provided at both ends of the longitudinal rod 18 .

[0038] Since the longitudinal rod 18 is slidably arranged in multiple suction cup assemblies, it is prevented that the longitudinal rod 18 falls off from the suction cup assemblies when the end picker is adjusted multiple times, resulting in the inability to perform subsequent work. By setting limit blocks 25 at both ends of the longitudinal rod 18, it is possible to prevent the longitudinal rod 18 from falling from the multiple suction cup assemblies, thereby ensuring the integrity and stability of the device when in use.

[0039] The elastic force of the zoom spring 20 on the transverse rod 17 is the same as the sum of the elastic forces of the plurality of zoom springs 20 on the longitudinal rod 18 .

[0040] Since the elastic force of the scaling spring 20 on the transverse rod 17 is the same as the sum of the elastic forces of the multiple scaling springs 20 on the longitudinal rod 18, when the end picker performs scaling to adjust the spacing between the multiple suction cup assemblies, the spacing between the suction cup assemblies on the transverse rod 17 and the longitudinal rod 18 can be adjusted in the same proportion, thereby ensuring the accuracy of the adjustment of the device and the stability of the subsequent transfer of the sheet material.

[0041] The limit blocks 25 are detachably mounted on both ends of the longitudinal rod 18 , and both ends of the second traction rope 26 are detachably connected to the fixing plate 16 and the mounting seat 21 .

[0042] Through the detachable installation limit block 25 and the second traction rope 26, multiple suction cup assemblies can be removed from the transverse rod 17 or the longitudinal rod 18, which is convenient for replacing a single damaged suction cup assembly and avoiding removing the entire end picker for repair, thereby ensuring the working efficiency of the device and repairing or replacing a single suction cup assembly, which can reduce the cost of repair or replacement.

[0043] The transverse rod 17 and the longitudinal rod 18 are both square in shape, and the mounting seat 21 is provided with through grooves adapted to the transverse rod 17 and the longitudinal rod 18 .

[0044] The through grooves on the mounting seat 21 that are adapted to the transverse rod 17 and the longitudinal rod 18 are all square, which can limit the position of the suction cup assembly, prevent the suction cup assembly from rotating freely on the transverse rod 17 or the longitudinal rod 18, and improve the stability of the device during operation.

[0045] Embodiment 2

[0046] Based on the first embodiment, a visual sensor is disposed at the bottom of the support plate 11 .

[0047] Since a visual sensor is provided, when the end picker is directly above the sheet material to be transferred, the second rotating motor 9 can be used to drive the end picker to rotate to adapt to the length and width of the sheet material, and then the winding device can be used to drive multiple suction cup assemblies to scale proportionally to adapt to sheets of the same proportion but different sizes. Through program control, the degree of automation of the device is improved, without the need for operator intervention, thereby reducing the operator's labor intensity and the operator's use cost.

[0048] Embodiment 3

[0049] On the basis of the second embodiment, multiple conveyor belts can be arranged on both sides and the rear end of the device. When the conveyor belt at the front end of the device continuously transports various specifications of sheet materials of the same proportion but different sizes to the device, the visual sensor can identify the sheets of different specifications, ensuring that the end picker can adjust the sheets of different sizes to adapt to the sheets according to the specifications of the sheets, and then drive the end picker to move back and forth on the moving track through the cooperation of the slider and the slide rail, ensuring that the moving seat moves to the corresponding conveyor belt position, and ensure that the end picker can be above the corresponding conveyor belt by rotating the first rotating motor forward or reversely by 90° or 180°, and then drive the end picker to descend by working with the cylinder, so that the sheet material adsorbed on the end picker falls on the conveyor belt, and by setting multiple conveyor belts, sheets of different specifications can be continuously moved to the corresponding transmission belts, so as to facilitate the corresponding subsequent processing respectively;

[0050] The free end of the support arm is provided with a second rotating motor for driving the end picker. When the end picker rotates following the first rotating motor, it prevents the length direction of the sheet material adsorbed by the end picker from not coinciding with the length direction of the conveyor belt, resulting in the conveyor belt being unable to effectively transport the sheet material. The second rotating motor drives the end picker to rotate forward or reverse 90°, so that the length direction of the sheet material coincides with the length of the conveyor belt in the opposite direction, which facilitates the conveyor belt to effectively transport the sheet material, further improving the practicability of the device and ensuring that the device can achieve the moving effect for sheets of the same proportion but different sizes.

The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
