Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a device for picking up and discharging materials from a disc. Background Technology

[0002] Equipment capable of automating the grasping and conveying of materials plays a vital role in modern industrial production. Common examples include robotic arms, belt conveyors, and elevators. Robotic arms, through programming, can precisely grasp and place materials, making them suitable for industries such as automobile manufacturing and consumer goods production. Belt conveyors rely on the continuous movement of a belt to achieve efficient material transport and are widely used in factory assembly lines. Elevators utilize mechanical structures to automatically transfer materials between different heights.

[0003] The authorization announcement number CN110950077B discloses a material adsorption and moving device. According to its instruction manual and drawings, the device can move any workpiece in the material frame to the desired position through the cooperation of the X, Y, and Z axis transmission mechanism. At the same time, the adsorption structure adsorbs the disc-shaped magnetic workpiece, realizing fully automated material adsorption operation.

[0004] However, this method has limitations when gripping disc-shaped materials. For example, the angle of this adsorption mechanism cannot be adjusted for freshly injection-molded plastic discs, so it cannot hold the freshly injection-molded plastic discs, resulting in a low degree of automation. Summary of the Invention

After the injection molding machine opens the mold, the disc is generally vertically aligned with the inside of the mold core.

A plurality of push rod support plates are connected to the end of the first clamping plate. A gripper push rod is slidably connected inside each push rod support plate. The top of the gripper push rod is connected to the clamping drive plate, and the bottom of the gripper push rod is hinged to one end of the disc gripper. The middle part of the disc gripper is hinged to one end of the gripper adjustment plate, and the top of the gripper adjustment plate is hinged to the bottom of the push rod support plate.

[0011] Preferably, the material placement mechanism includes a fourth electric slide rail, a placement support frame, a placement plate, and a first limiting rod.

This automatically completes the unloading of the discs from the surface of the placement plate without affecting the subsequent return of the placement plate to its original position for stacking discs, thus improving the automation level of the entire equipment.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] like Figures 1 to 5 As shown, a device for picking up and putting down materials from a disc includes a worktable 1, a conveyor support frame 2 disposed on the surface of the worktable 1, and an electric slide rail assembly 3 connected to the top of the conveyor support frame 2, which is capable of changing the horizontal and vertical positions.

[0023] The electric slide rail assembly 3 includes a first electric slide rail 31, a second electric slide rail 32, and a third electric slide rail 33. The top of the conveying support frame 2 is provided with the first electric slide rail 31. The surface of the slider of the first electric slide rail 31 is provided with the second electric slide rail 32. The second electric slide rail 32 is perpendicular to the first electric slide rail 31. The surface of the slider of the second electric slide rail 32 is provided with the third electric slide rail 33. The surface of the slider of the third electric slide rail 33 is connected to an angle flipping mechanism 4.

[0024] During the sliding process of the slider of the first slide rail 31, the position of the angle flipping mechanism 4 relative to the worktable 1 in the X-axis direction can be changed. During the sliding process of the slider of the second slide rail 32, the position of the angle flipping mechanism 4 relative to the worktable 1 in the Y-axis direction can be changed. During the sliding process of the slider of the third electric slide rail 33, the position of the angle flipping mechanism 4 relative to the worktable 1 in the Z-axis direction can be changed.

[0025] In this embodiment, the end of the electric slide rail assembly 3 is connected to an angle flipping mechanism 4. Specifically, the angle flipping mechanism 4 includes a flipping support frame 41, a first cylinder 42, a gear support shaft 43, a metal gear 44, and a flipping drive plate 45. The top of the flipping support frame 41 is provided with the first cylinder 42, the bottom of the flipping support frame 41 is provided with the gear support shaft 43, the surface of the gear support shaft 43 is connected to the metal gear 44, the tooth groove 421 at the end of the first cylinder 42 is connected to the surface of the metal gear 44, and the bottom of the metal gear 44 is connected to the flipping drive plate 45.

[0026] like Figure 3 As shown, when the piston rod of the first cylinder 42 extends downward, it drives the metal gear 44 to rotate. When the metal gear 44 rotates, it also causes the angle of the flip drive plate 45 to change. The gear support shaft 43 mainly plays a supporting and guiding role during the rotation of the metal gear 44.

[0027] In this embodiment, the end of the angle flipping mechanism 4 is connected to a disc clamping mechanism 5. Specifically, the disc clamping mechanism 5 includes a first clamping plate 51, a support column 52, a clamping drive plate 53, a second cylinder 54, and a gripper assembly 55. The surface of the first clamping plate 51 is provided with a plurality of support columns 52. The surface of the support columns 52 is slidably connected to the clamping drive plate 53. The top of the support columns 52 is connected to the bottom of the flipping drive plate 45 through a fixing plate. The surface of the clamping drive plate 53 is provided with a second cylinder 54. The piston rod of the second cylinder 54 passes through the surface of the clamping drive plate 53 and is connected to the first clamping plate 51. The end of the clamping drive plate 53 is connected to a plurality of gripper assemblies 55. When the clamping drive plate 53 moves, it can drive the gripper assembly 55 to grasp the disc.

[0028] The gripper assembly 55 includes a push rod support plate 551, a gripper push rod 552, a disc gripper 553, and a gripper adjustment plate 554. The end of the first clamping plate 51 is connected to a plurality of push rod support plates 551. Each push rod support plate 551 has a gripper push rod 552 slidably connected inside. The top of the gripper push rod 552 is connected to the clamping drive plate 53, the bottom of the gripper push rod 552 is hinged to one end of the disc gripper 553, the middle of the disc gripper 553 is hinged to one end of the gripper adjustment plate 554, and the top of the gripper adjustment plate 554 is hinged to the bottom of the push rod support plate 551.

[0029] Since the discs that come out after the injection molding machine opens the mold are basically vertically aligned with the inside of the mold core, under this premise, the angle of the flip drive plate 45 changes, which can cause the entire gripper assembly 55 to flip 90 degrees. At this time, the gripper assembly 55 can perform a clamping operation. After clamping is completed, the angle of the flip drive plate 45 is reset, and then the electric slide rail assembly 3 is used to adjust the position for stacking.

[0030] During the gripping process, the piston rod of the second cylinder 54 extends and generates a counterforce with the first clamping plate 51, causing the entire clamping drive plate 53 to slide. Simultaneously, the clamping drive plate 53 slides the gripper push rod 552 within the push rod support plate 551. During this sliding process, the push rod support plate 551 first pulls the end of the disc gripper 553 to rotate. The disc gripper 553 is restricted by the gripper adjustment plate 554 during rotation, allowing it to be parallel and perpendicular to the push rod support plate 551. When the sidewall of each disc gripper 553 is perpendicular to the sidewall of the push rod support plate 551, it can grip the disc; when the sidewall of each disc gripper 553 is parallel to the sidewall of the push rod support plate 551, it can release the disc.

[0031] In this embodiment, the surface of the workbench 1 is also provided with a material placement mechanism 6 and a material lifting mechanism 7. The material placement mechanism 6 can slide relative to the workbench 1. During the sliding process, the placement area of ​​the material placement mechanism 6 and the lifting area of ​​the material lifting mechanism 7 do not interfere with each other.

[0032] The material placement mechanism 6 includes a fourth electric slide rail 61, a placement support frame 62, a placement plate 63, and a first limiting rod 64. The surface of the slider of the fourth electric slide rail 61 is provided with the placement support frame 62. The top of the placement support frame 62 is provided with several placement plates 63. There is a gap between adjacent placement plates 63. The surface of each placement plate 63 is provided with a first limiting rod 64. The gap between adjacent first limiting rods 64 can hold disc-shaped materials.

[0033] After the electric slide rail assembly 3 adjusts the position of the gripper assembly 55, the gripper assembly 55 stacks the discs inside the gap between adjacent first limit rods 64. When a specified number are stacked, the slider of the fourth electric slide rail 61 drives the entire placement support frame 62 to slide and adjust its position during the sliding process until it moves to the lifting area of ​​the material lifting mechanism 7.

[0034] The material lifting mechanism 7 includes a third cylinder 71, a lifting support plate 72, a lifting placement frame 73, a lifting plate 74, and second limiting rods 75. The third cylinder 71 is located at the bottom of the worktable 1. The piston rod end of the third cylinder 71 passes through the surface of the worktable 1 and is connected to the lifting support plate 72. The lifting support plate 72 extends outward from its side to provide the lifting placement frame 73. The surface of the lifting placement frame 73 is provided with the lifting plate 74, the width of which is smaller than the gap between adjacent placement plates 63. The surface of the lifting plate 74 is provided with several second limiting rods 75, and the gap between adjacent second limiting rods 75 is sufficient to hold disc-shaped materials. The surface of the worktable 1 is also provided with a slide rail support plate 78. The surface of the slide rail support plate 78 is provided with several first slide rails 76, and each first slide rail 76 is slidably connected to a first slider 77. The side of the lifting support plate 72 is connected to the surface of the first slider 77.

[0035] Before the placement plate 63 slides toward the lifting plate 74, the piston rod of the third cylinder 71 retracts, driving the entire lifting placement frame 73 and the lifting plate 74 to move downwards until several second limit rods 75 no longer interfere with the disc on the surface of the placement plate 63.

[0036] When the placement plate 63 is directly above the lifting plate 74, the piston rod of the third cylinder 71 extends, driving the entire lifting placement frame 73 and the lifting plate 74 upward. Since the width of the lifting plate 74 is smaller than the gap between adjacent placement plates 63, it will not interfere with the placement plates 63 during the continuous upward movement, and the placement plates 63 and the lifting plate 74 gradually become a single plane.

[0037] At this point, the disc is simultaneously held in place by the gap between the adjacent first limiting rod 64 and the second limiting rod 75. Then, the piston rod of the third cylinder 71 extends upwards, raising the height of the lifting plate 74 above the height of the placement plate 63, until the first limiting rod 64 is completely disengaged from the discs in the vertical direction. The discs on the surface of the lifting plate 74 can then be unloaded by other mechanisms, while the placement plate 63 returns to its initial position under the sliding action of the fourth electric slide rail 61.

[0038] Working principle and usage of this utility model:

[0039] When it is necessary to remove the plastic tray that has just been injected by the injection molding machine, the slider of the first slide rail 31 can change the position of the angle flipping mechanism 4 relative to the worktable 1 in the X-axis direction during the sliding process. The slider of the second slide rail 32 can change the position of the angle flipping mechanism 4 relative to the worktable 1 in the Y-axis direction during the sliding process. The slider of the third electric slide rail 33 can change the position of the angle flipping mechanism 4 relative to the worktable 1 in the Z-axis direction during the sliding process.

[0040] Once the designated position is reached, the piston rod of the first cylinder 42 extends downwards, driving the metal gear 44 to rotate. As the metal gear 44 rotates, it simultaneously causes the angle of the flip drive plate 45 to change, causing the entire gripper assembly 55 to flip ninety degrees. At this time, the gripper assembly 55 clamps the object.

[0041] During the clamping process, the piston rod of the second cylinder 54 extends and generates a counterforce with the first clamping plate 51, causing the entire clamping drive plate 53 to slide. Simultaneously, the clamping drive plate 53 slides within the push rod support plate 551 during this sliding process. The push rod support plate 551 first pulls the end of the disc clamp 553 to rotate during this process. The disc clamp 553 is then restricted by the clamp adjusting plate 554, allowing it to complete the clamping action.

[0042] After clamping, the position of the gripper assembly 55 is readjusted so that the discs gradually stack within the gap between adjacent first limiting rods 64. Once a specified number are stacked, the slider of the fourth electric slide rail 61 slides and adjusts the position of the entire placement support frame 62. Before the placement plate 63 slides towards the lifting plate 74, the piston rod of the third cylinder 71 retracts, causing the entire lifting placement frame 73 and lifting plate 74 to move downwards until several second limiting rods 75 no longer interfere with the discs on the surface of the placement plate 63. When the placement plate 63 is directly above the lifting plate 74, the piston rod of the third cylinder 71 extends, causing the entire lifting placement frame 73 and lifting plate 74 to move upwards. Because the width of the lifting plate 74 is smaller than the gap between adjacent placement plates 63, it does not interfere with the placement plates 63 during the upward movement, and the placement plates 63 and lifting plates 74 gradually become a single plane.

[0043] At this point, the disc is simultaneously held in place by the gap between the adjacent first limiting rod 64 and the second limiting rod 75. Then, the piston rod of the third cylinder 71 extends upwards, raising the height of the lifting plate 74 above the height of the placement plate 63, until the first limiting rod 64 is completely disengaged from the discs in the vertical direction. The discs on the surface of the lifting plate 74 can then be unloaded by other mechanisms, while the placement plate 63 returns to its initial position under the sliding action of the fourth electric slide rail 61.
