Description

Technical Field

[0002] In order to reduce manual operation during the processing of thermos cups, large manipulators are usually equipped to pick up and feed materials. The manipulators that are equipped with traditional thermos cup processing equipment are often installed separately and externally near the thermos cup processing equipment. Such manipulators occupy a large area, have slow operation steps and are not flexible enough. Such equipment has poor versatility. Different types of clamping molds need to be replaced to clamp thermos cups of different sizes. At the same time, the process parameters need to be reset. The operation is complicated and inefficient, which greatly increases production costs. Such manipulators are often complex in structure and large in size. They are not flexible enough to grasp the thermos cup within a certain three-dimensional space, and the grasping is not reliable enough. The thermos cup cannot be accurately placed in the specified position, and the grasping efficiency is low. Therefore, it is necessary to design an automatic gripping device for thermos cups to overcome the above difficulties. Summary of the Invention

The first connecting shaft and the second connecting shaft are respectively mounted on the first mounting seat through bearings. The second gear is sleeved on the first connecting shaft and rotates synchronously with it. The second gear is arranged adjacent to the first gear and is always in a state of mutual meshing. The first connecting shaft is provided with a first connecting rod fixedly connected to the end away from the first mounting seat. The first connecting rod and the first connecting shaft are arranged perpendicular to each other and rotate synchronously. The second connecting rod is provided with a second connecting rod fixedly connected to the end away from the first mounting seat. The second connecting rod and the second connecting shaft are arranged perpendicular to each other and rotate synchronously.

[0018] When the piston shaft of the first cylinder reciprocates and extends, it drives the clamping arms to move closer or farther away from each other, so that the thermos cup can be clamped conveniently; because the extension and contraction direction of the piston shaft of the first cylinder is perpendicular to the movement direction of the first mounting base, the first mounting base moves up and down in the vertical direction under the drive of the lifting assembly, so that the opening of the clamped thermos cup is always in the vertical direction.

The interval between placing and removing the thermos cup is short, and the transfer efficiency is high. At the same time, the components for placing and removing the thermos cup are all installed on the fuselage platform 1, with a compact structure and small space occupation.

[0036] The lifting assembly 4 includes a second motor 41, a coupling 42 and a first screw rod 43. The second motor 41 is fixedly mounted on the top of the mounting frame 3. Both ends of the first screw rod 43 are mounted on the mounting frame 3 through bearings. The first screw rod 43 is connected to the motor shaft of the second motor 41 through the coupling 42. The motor shaft of the second motor 41 rotates synchronously with the first screw rod 43; the motor shaft of the second motor 41 is vertically downward and is arranged coaxially with the first screw rod 43; the first mounting seat 9 is provided with a first protrusion 91 on the end face facing away from the mold 2, and the first protrusion 91 is sleeved and mounted on the first screw rod 43, and the first protrusion 91 is provided with a thread that engages with the first screw rod 43. The second motor 41 drives the first screw 43 to rotate while it is working, and the first screw 43 drives the first mounting seat 9 to move up and down while it is rotating; the first mounting seat 9 is connected to the second mounting seat 10, and the second mounting seat 10 is connected to the third mounting seat 11, and the third mounting seat 11 is provided with a clamping assembly 7, so when the first mounting seat 9 moves up and down, it will drive the thermos cup on the clamping assembly 7 to move up and down. The mounting frame 3 is provided with a pair of first guide rails 31 that are arranged in a vertical direction, and the first mounting seat 9 is installed on the first guide rails 31. When the second motor 41 drives the first screw 43 to rotate, the first mounting seat 9 moves up and down along the first guide rails 31; the lifting assemblies 4 are arranged in pairs on the left and right sides of the mold 2, and each lifting assembly 4 drives each first mounting seat 9 to move up and down separately, and each first mounting seat 9 is arranged on the outside of the mold 2. When the second motor 41 drives the first screw rod 43 to rotate, the first mounting seat 9 will move up and down along the first guide rail 31; the first mounting seats 9 on the left and right sides move on their respective corresponding first guide rails 31, so that there will be no interference when loading and unloading the thermos cup and the efficiency will be higher.

[0037] The swing assembly 5 also includes a third motor 53, a first gear 54, a second gear 55, a first connecting shaft 56 and a second connecting shaft 57. The third motor 53 is fixedly mounted on the end surface of the first mounting seat 9 facing away from the mold 2. The first gear 54 is connected to the motor shaft of the third motor 53 and rotates synchronously with it. The first gear 54 is arranged on the end surface of the first mounting seat 9 facing the mold 2; the first connecting shaft 56 and the second connecting shaft 57 are respectively mounted on the first mounting seat 9 through bearings, the second gear 55 is sleeved on the first connecting shaft 56 and rotates synchronously with it, the second gear 55 is arranged adjacent to the first gear 54 and is always in a mutually meshing state; the first connecting shaft 56 is provided with a first connecting rod 51 fixedly connected to the end away from the first mounting seat 9, the first connecting rod 51 and the first connecting shaft 56 are arranged perpendicular to each other and rotate synchronously; the second connecting shaft 57 is provided with a second connecting rod 52 fixedly connected to the end away from the first mounting seat 9, the second connecting rod 52 and the second connecting shaft 57 are arranged perpendicular to each other and rotate synchronously, and the first connecting rod 51 and the second connecting rod 52 rotate in the same direction relative to the first mounting seat 9. When the third motor 53 is in operation, it drives the first gear 54 to rotate. When the first gear 54 rotates, it drives the second gear 55 to mesh and rotate. The rotation of the second gear 55 drives the first connecting shaft 56 to rotate. The rotation of the first connecting shaft 56 drives the first connecting rod 51 to rotate. One end of the first connecting rod 51 and one end of the second connecting rod 52 are both hinged to the second mounting base 10, and the other ends of the first connecting rod 51 and the other ends of the second connecting rod 52 are both pivotally connected to the first mounting base 9. Therefore, when the first connecting rod 51 rotates, the second connecting rod 52 will be driven to rotate synchronously. When the first connecting rod 51 and the second connecting rod 52 rotate synchronously, the second mounting base 10 will be driven to rotate relative to the first mounting base 9. The end of the first connecting rod 51 away from the first mounting seat 9 is hinged to the second mounting seat 10 through a pin, and the end of the second connecting rod 52 away from the first mounting seat 9 is hinged to the second mounting seat 10 through a pin; the second mounting seat 10 includes a horizontal placement plate 101 and a vertical side plate 102, and the first connecting rod 51 and the second connecting rod 52 are both hinged to the vertical side plate 102 through a pin; the horizontal placement plate 101 is always parallel to the horizontal plane, and a rotating component 6 is provided on the horizontal placement plate 101. The first connecting rod 51 is hinged to the vertical side panel 102, and the second connecting rod 52 is hinged to the vertical side panel 102. The vertical side panel 102 and the horizontal placement plate 101 are arranged perpendicular to each other. Then the horizontal placement plate 101 is always in a horizontal state under the limitation of the first connecting rod 51 and the second connecting rod 52. In this way, the second mounting seat 10 is always in a horizontal state during the rotation process. Then the opening of the thermos cup clamped by the clamping assembly 7 is always in a vertical direction and will not be offset. In this way, the thermos cup can be accurately transferred to the placement mold 2, thereby improving the loading efficiency of the thermos cup.The rotating assembly 6 includes a first motor 61 and a connecting sleeve 62. The first motor 61 is mounted on the upper end surface of the horizontal plate 101, and the connecting sleeve 62 is fixedly mounted on the lower end surface of the horizontal plate 101. The connecting sleeve 62 is mounted on the motor shaft of the first motor 61 via a bearing. The motor shaft of the first motor 61 is vertically downward and fixedly connected to the third mounting base 11. When the first motor 61 is in operation, it drives the third mounting base 11 to rotate around the motor shaft of the first motor 61. The third mounting base 11 is connected to the clamping assembly 7. In this way, the operation of the first motor 61 can drive the thermos cup to rotate relative to the second mounting base 10.

[0038] The clamping assembly 7 includes a first cylinder 71 and a pair of clamping arms 72. The first cylinder 71 is fixedly mounted on the third mounting seat 11. The first cylinder 71 is a bidirectional cylinder. The two piston shafts of the first cylinder 71 are fixedly connected to each clamping arm 72. The extension and retraction direction of the piston shaft of the first cylinder 71 is perpendicular to the direction of movement of the first mounting seat 9. The placement mold 2 is a columnar body and its axial direction is parallel to the direction of movement of the first mounting seat 9. When the piston shaft of the first cylinder 71 reciprocates and retracts, it drives the clamping arms 72 to move closer or further away from each other, which makes it easier to clamp the thermos cup. Because the extension and retraction direction of the piston shaft of the first cylinder 71 is perpendicular to the direction of movement of the first mounting seat 9, the first mounting seat 9 moves up and down in the vertical direction under the drive of the lifting assembly 4, so that the opening of the clamped thermos cup is always in the vertical direction. A fixing device 8 for pressing the thermos cup is provided just above the mold 2, and the fixing device 8 includes a fourth mounting seat 81, a fourth motor 82, a mounting plate 83, a second screw rod 84, a second cylinder 85 and a pressing member 86; the fourth motor 82 is fixedly mounted on the top of the mounting frame 3, and both ends of the second screw rod 84 are mounted on the mounting frame 3 through bearings. The motor shaft of the fourth motor 82 is connected to the second screw rod 84 and rotates synchronously. The mounting frame 3 is provided with a second guide rail 32 arranged in pairs. The fourth mounting seat 81 is mounted on the second guide rail 32. The end surface of the fourth mounting seat 81 facing away from the mold 2 is provided with a second protrusion 87, which is sleeved and mounted on the second screw rod 84. The second protrusion 87 has a threaded portion that intermeshes with the second screw rod 84. The horizontal end surface of the fourth mounting seat 81 is provided with a second cylinder 85 fixedly connected thereto. The piston shaft of the second cylinder 85 is fixedly connected to the mounting plate 83. The lower end surface of the mounting plate 83 is provided with a pressing member 86 fixedly connected thereto. When the thermos cup is to be fixed in advance during the necking operation, the fourth motor 82 is driven to rotate the second screw rod 84. The rotation of the second screw rod 84 simultaneously drives the fourth mounting seat 81 closer to the thermos cup. When the fourth mounting seat 81 approaches the thermos cup, the fourth motor 82 stops working, and then the second cylinder 85 is driven to push the mounting plate 83 closer to the thermos cup. As the mounting plate 83 approaches the thermos cup, the pressing member 86 below the mounting plate 83 abuts against the mouth of the thermos cup, thus securing the thermos cup. The upper end surface of the mounting plate 83 is provided with a plurality of guide posts 88 fixedly connected thereto, and the fourth mounting seat 81 is mounted on each of the guide posts 88. The guide posts 88 are arranged vertically. The installation of the guide posts 88 allows the mounting plate 83 to approach the thermos cup only in the direction of the guide posts 88, thus ensuring that the pressing member 86 can abut against the opening of the thermos cup.

[0039] The specific working process of this embodiment is as follows: when it is necessary to process the thermos cup on the assembly line, the thermos cup is grabbed from the assembly line and placed on the mold 2 by the loading device, and the loading device includes a lifting component 4, a swing component 5, a rotating component 6 and a clamping component 7 arranged on the left side of the mold 2; after the thermos cup is processed, the thermos cup is taken away from the mold 2 by the unloading device, and the unloading device includes a lifting component 4, a swing component 5, a rotating component 6 and a clamping component 7 arranged on the right side of the mold 2; when the loading device grabs the first thermos cup to be processed and places it on the mold 2, the clamping component on the right side of the unloading device Component 7 is placed near mold 2 and is in a waiting state. After placing the first thermos cup to be processed, the loading device will continue to the assembly line to grab the second thermos cup to be processed, and then grab the second thermos cup to be processed and place it near mold 2 to wait for further processing. After the first thermos cup is processed, the unloading device on the right side removes the first thermos cup from mold 2. After removing the first thermos cup, the unloading device immediately returns to the vicinity of mold 2 to wait for the second thermos cup to be removed. When the first thermos cup is removed by the unloading device, the loading device will immediately place the second thermos cup waiting to be processed on mold 2 for processing. Then, the loading and unloading devices will repeat the above steps, cooperating with each other to complete the loading and unloading process of the thermos cups.

[0040] The specific working process of the loading device is as follows: the first cylinder 71 on the left clamping assembly 7 controls the clamping arms 72 to move closer to each other to clamp the thermos cup, the lifting assembly 4 controls the first mounting seat 9 to move up, and the clamping assembly 7 will clamp the thermos cup and move it up and out of the assembly line, and then the swing assembly 5 controls the second mounting seat 10 to rotate and make it close to the placement mold 2; at the same time, the third mounting seat 11 rotates when the rotating assembly 6 works; while the third mounting seat 11 rotates, it drives the thermos cup on the clamping assembly 7 to rotate from the direction facing away from the placement mold 2 to the direction facing the placement mold 2, and at this time the thermos cup is just above the placement mold 2; then the lifting assembly 4 further controls the first mounting seat 9 to move down, and finally the first cylinder 71 on the clamping assembly 7 controls the clamping arms 72 to move away from each other, so that the loading process of the thermos cup is completed.

[0041] Similarly, the working principle of the unloading device is the same as that of the loading device. When the processing of the thermos cup is completed, the unloading device will immediately remove the thermos cup from the placement mold 2.

[0042] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
