Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a mechanical synchronous unlocking mechanism of multiple electromagnetic locks and a handling robot. Background Art

[0002] In order to improve product quality, most factories now have safety and dust-proof cleanliness requirements for materials transported within the factory, and will install cabinet doors on the handling robots to isolate them from the outside environment. The traditional method uses mechanical locks or electromagnetic locks to lock the door. When the cabinet door is closed, the lock hook in the electromagnetic lock body will hook the lock buckle fixed on the cabinet door. When the electromagnetic lock is powered on, due to the electromagnetism principle of the electromagnet, a strong suction force is generated, which will bounce the lock hook and cancel the locking of the lock buckle, thereby achieving the effect of opening the door.

[0003] Electromagnetic locks can achieve automated control and improve production efficiency, so they are gradually being widely used. However, in emergency situations such as power failure or failure of the electronic control system, conventional electromagnetic locks may not be able to open normally, which requires a mechanical unlocking device for manual unlocking. However, for handling robots with multiple doors, the electromagnetic locks corresponding to each door usually need to be manually unlocked one by one when opening, which is less convenient and has low unlocking efficiency. In addition, traditional electromagnetic locks are generally equipped with separate mechanical unlocking devices, which are also more expensive. Utility Model Content

[0036] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the utility model and implement it, but the embodiments are not intended to limit the utility model.

[0037] Reference Figure 1 to Figure 6 As shown, an embodiment of the utility model provides a transport robot, including a mobile body 1000 , a receiving assembly 2000 and a synchronous unlocking mechanism 4000 .

[0038] The mobile body 1000 includes at least a plurality of wheel sets for realizing movement to different positions. Generally, a robot mobile chassis can be used.

[0039] The storage assembly 2000 includes a storage cabinet 100 disposed on a mobile body 100, a plurality of cabinet doors 110 hinged to the storage cabinet 100, a plurality of locks 120 disposed on the opening side of the cabinet doors 110, and a plurality of electromagnetic locks 3000 disposed in the storage cabinet 100. The number of the locks 120 and the electromagnetic locks 3000 is equal and they are disposed one by one. The electromagnetic locks 3000 are disposed in an upper and lower distribution.

[0040] The synchronous unlocking mechanism 4000 is arranged in the receiving cabinet 100. Specifically, the synchronous unlocking mechanism 4000 includes a lifting assembly 300, a plurality of paddles 400 and a lifting assembly 500. The lifting assembly 300 includes a lifting member 310, a guide shaft 320 installed on the top of the lifting member 310, a compression spring 330 sleeved on the guide shaft 320, a linear bearing 340 slidingly matched with the guide shaft 320, and a linear bearing seat 350 for mounting the linear bearing 340. The two ends of the compression spring 330 are respectively abutted against the linear bearing 340 and the lifting member 310. The paddle 400 is used to mechanically unlock the electromagnetic lock 3000, and the paddle 400 is arranged on the lifting member 310 at intervals up and down. The number of paddles 400 is equal to the number of electromagnetic locks 3000, and is arranged correspondingly up and down to the mechanical unlocking switch that triggers the electromagnetic lock 3000. The lifting assembly 500 includes a guide seat 510, a first moving member 530 and a second moving member 520 movably disposed in the guide seat 510; the first moving member 530 and the second moving member 520 are coupled to each other to achieve linkage, so that when the first moving member 530 moves in the horizontal direction, the second moving member 520 moves in the vertical direction. The second moving member 520 is fixedly connected to the lifting member 310.

[0041] Specifically, the first moving member 530 of the present embodiment drives the second moving member 520 to rise, thereby causing the lifting member 310 and the paddle 400 to rise, so that the rising paddle 400 can push the mechanical unlocking switch of the electromagnetic lock 3000, thereby unlocking the electromagnetic lock 3000. After the electromagnetic lock 3000 is unlocked, the compressed compression spring 330 reacts on the lifting member 310 due to the rise of the lifting member 310, causing the lifting member 310 to fall and reset. It can be seen that the present application can realize the synchronous unlocking of multiple door electromagnetic locks 3000, thereby improving the unlocking efficiency. The present application has a simple structure, convenient operation, low cost, and is easy to promote and apply.

[0042] Furthermore, the receiving assembly 2000 includes at least one set of two cabinet doors 110 arranged side by side in the X direction. The electromagnetic locks 3000 corresponding to the two cabinet doors 110 arranged side by side in the X direction are staggered in the X direction. Figure 1 , the X direction mentioned in this embodiment specifically refers to the forward or backward direction of the handling robot. In practical applications, the scope of understanding of the X direction can be expanded, for example, it can be understood as the length direction or width direction of the storage cabinet 100. In another possible embodiment, the storage component 2000 includes at least two cabinet doors 110 arranged in the vertical direction. Of course, in practical applications, the storage component 2000 includes both cabinet doors 110 arranged in the horizontal X direction and cabinet doors 110 arranged in the vertical direction. Thus, multiple groups of cabinet doors arranged in the vertical direction are formed, and each group of cabinet doors includes two cabinet doors arranged in the X direction. Specifically, this embodiment can realize the synchronous unlocking of more electromagnetic locks 3000, which is more convenient and quick to use. It can be customized according to actual needs to meet the needs of different application scenarios. In addition, the electromagnetic locks 3000 corresponding to the two cabinet doors 110 arranged side by side in the X direction are staggered in the X direction, so that interference with the electromagnetic locks 3000 adjacent to the X direction can be avoided during the up and down movement of the lifting component 300.

[0043] Furthermore, a vertically extending lifting channel is provided in the storage cabinet 100, and a synchronous unlocking mechanism 4000 is provided in the lifting channel (not shown in the figure). The lifting channel is provided in the middle position of the storage cabinet. The linear bearing seat 350 is fixedly connected to the storage cabinet 100. The guide seat 510 is fixedly connected to the storage cabinet 100. Specifically, the lifting member 310 in this embodiment is located in the lifting channel, so that the inner side of the lifting member 310 away from the jacking assembly 500 can be supported to prevent the lifting member 310 from bending during the process of the jacking assembly 500 applying force to drive the lifting member 310 to rise and fall.

[0044] Furthermore, the storage cabinet 100 is provided with a mechanical unlocking hole 130 which is opposite to the position of the first moving member 530. Specifically, the mechanical unlocking hole 130 is provided in this embodiment, so that when a power failure or an electronic control system fails, a round rod or other rod-shaped object can be used to apply a horizontal inward force through the mechanical unlocking hole 130 to push the first moving member 530 to move horizontally, so that the lifting member 310 rises, so that the paddle 400 of the lifting member 310 pushes the mechanical unlocking switch of the electromagnetic lock 3000, thereby realizing simultaneous unlocking of multiple electromagnetic locks 3000.

[0045] Further, the guide seat 510 is provided with a horizontal chute 511 in the horizontal direction, and a horizontal limit groove 512 and a vertical limit groove 514 are provided on both side walls of the horizontal chute 511. A first belt shaft bearing 532 adapted to the horizontal limit groove 512 is provided on both sides of the first moving member 530. A second belt shaft bearing 521 adapted to the vertical limit groove 514 is provided on both sides of the second moving member 520. The guide seat 510 includes a base plate and two L-shaped side plates relatively arranged on the base plate, and the inner space of the two L-shaped side plates is defined as the horizontal chute 511. The horizontal side of the L-shaped side plate is provided with a horizontal limit groove 512. The vertical side of the L-shaped side plate is provided with a vertical limit groove 514. Specifically, the cooperation of the first belt shaft bearing 532 and the horizontal limit groove 512 and the cooperation of the second belt shaft bearing 521 and the vertical limit groove 514 in the present embodiment play a guiding role in the movement of the first moving member 530 and the second moving member 520 respectively.

[0046] Further, the top of the first moving member 530 is set to the inclined surface 531 towards the second moving member 520. The second moving member 520 is provided with a rolling bearing 540 on one side towards the inclined surface 531, and the rolling bearing 540 and the inclined surface 531 are rolling matched. In certain embodiments, the rolling bearing 540 is installed on the second moving member 520 by a bearing mandrel 550. In certain embodiments, the second moving member 520 is fixedly connected with the lifting member 310 by a connecting member 560. The connecting member 560 is an L-shaped structure. The connecting member 560 is connected with the lifting member 310 and the second moving member 520 by bolts respectively. Specifically, the rolling bearing 540 in the present embodiment can roll along the hypotenuse of the first moving member 530, so that the rolling bearing 540 rolls upward along the hypotenuse of the first moving member 530 by pushing the first moving member 530 to a side of the second moving member 520, and then the second moving member 520 is pushed to move upward, so as to realize the rise of the lifting member 310, and the structure is simple and the operation is stable and reliable.

[0047] Furthermore, the lifting member is provided with at least one limiting waist hole 620 along the length direction / lifting direction. The limiting waist hole 620 is provided on the lifting member 310, and the limiting waist hole 620 extends vertically. In this embodiment, a limiting screw 610 is provided through which the limiting screw 610 is threadedly connected with the receiving cabinet 100. Through the cooperation of the limiting screw 610 and the limiting waist hole 620, the lifting member 310 can be limited from lifting up and down and shaking left and right, thereby further ensuring that the mechanical unlocking switch of the electromagnetic lock 3000 corresponds to the paddle 400 up and down.

[0048] Furthermore, the lifting member 310 is made of aluminum bars, which has the advantages of being lightweight, high in strength, and corrosion-resistant.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the utility model creation.
