[0032] The present invention provides a leather sheet separating mechanism, which includes a support body 1, a driver 2, a support arm 3 and a suction cup assembly 4. Among them, the driver 2 is installed on the support body 1, the output shaft of the driver 2 is connected to the support arm 3 and the driver 2 can drive the support arm 3 to rotate. The number of the suction cup assemblies 4 is multiple, all the suction cup assemblies 4 are installed on the support arm 3 and the suction cup assemblies 4 can suck the leather. For the leather sheet separating mechanism provided by the present invention, first start the driver 2 to drive the support arm 3 to rotate towards the direction close to the leather conveyor 10, so that the suction cup assembly 4 is close to the topmost leather on the leather conveyor 10. Then start the suction cup assembly 4 to make the suction cup assembly 4 suck the leather. Then rotate the support arm 3 in the reverse direction, and the topmost leather will move along with the movement of the support arm 3, so that the topmost leather is separated from other leathers. Using mechanical operation to separate the leather has a relatively high efficiency, and solves the technical problem of relatively low efficiency in the prior art of manually separating the leather on the conveyor.

[0033] As an optional implementation manner, the support arm 3 is of an L-shaped structure. The short rod of the support arm 3 is connected to the driver 2, and the long rod of the support arm 3 is connected to the suction cup assembly 4. When the support arm 3 rotates under the action of the driver 2, the suction cup assembly 4 makes a circular motion or a swinging motion under the action of the support arm 3.

[0034] As an optional implementation manner, the suction cup assembly 4 includes a floating cylinder 41, a vacuum non-marking suction cup 42 and a connecting seat. The floating cylinder 41 is connected to the support arm 3 through the connecting seat. The floating cylinder 41 is connected to the vacuum non-marking suction cup 42. The floating cylinder 41 is located at the side wall of the support arm 3. All the suction cup assemblies 4 are distributed along the length direction of the long rod of the support arm 3.

[0035] As an optional implementation manner, a vacuum pump is further included. The vacuum pump is connected to the suction cup assembly 4 through an air pipeline. When the number of the vacuum pumps is the same as the number of the suction cup assemblies 4, one vacuum pump is correspondingly connected to one suction cup assembly 4. Or when the number of the vacuum pumps is one, or when the number of the vacuum pumps is less than the number of the suction cup assemblies 4, one vacuum pump is correspondingly connected to multiple suction cup assemblies 4.

[0036] As an optional implementation manner, a controller is further included. The driver 2, the vacuum pump, the solenoid valve and the negative pressure detection sensor are all electrically connected to the controller. The air pipeline is provided with a solenoid valve and a negative pressure detection sensor. The number of the negative pressure detection sensors is the same as the number of the suction cup assemblies 4 and they are in one-to-one correspondence. The controller can control the start, stop, forward rotation and reverse rotation of the driver 2. The driver 2 can be a servo reduction motor. The controller can control the start and stop of the vacuum pump. The controller can control the opening and closing of the solenoid valve. The negative pressure detection sensor can detect whether the suction cup assembly 4 sucks the leather, and then transmit the information to the controller. The controller controls the working states of the driver 2, the vacuum pump and the solenoid valve according to this information.

[0037] As an optional implementation manner, it further includes a laser distance measurement sensor 5. The laser distance measurement sensor 5 is installed on the support arm 3 and is electrically connected to the controller. The laser distance measurement sensor 5 can detect the distance between the support arm 3 and the leather on the top layer of the leather transport rack 10 in real time, so as to transmit the actual distance information to the controller in real time. The controller will compare the actual distance information with the preset distance information. When the actual distance information is greater than the preset distance information, the driver 2 continues to work; when the actual distance information is equal to the preset distance information, the driver 2 stops working, and at this time, the suction cup assembly 4 is close to the leather on the top layer of the leather transport rack 10.

[0038] As an optional implementation manner, a base 11 is provided at the bottom of the support body 1. The base 11 is fixed to the ground by bolts. An installation seat 12 is provided at the top of the support body 1. The driver 2 and the support arm 3 are located on both sides of the installation seat 12 respectively. The installation seat 12 is connected to the outer shell of the driver 2, and the output shaft of the driver 2 passes through the installation seat 12 and is connected to the support arm 3.

[0039] The present invention provides a leather automatic loading and unloading device, which includes a leather transport rack 10, a leather grasping mechanism 30, a flattening mechanism 40, a processing structure 50 and a leather separating mechanism 20. The leather transport rack 10, the leather separating mechanism 20, the leather grasping mechanism 30, the flattening mechanism 40 and the processing structure 50 are arranged and distributed in sequence. The working process of the leather automatic loading and unloading device is as follows: First, there are multiple pieces of leather stacked on the leather transport rack 10. Then, the leather separating mechanism 20 is started, and the support arm 3 rotates first, so that the suction cup assembly 4 is close to the leather on the top layer of the leather transport rack 10. Then, the suction cup assembly 4 sucks the leather.

[0040] Then, the support arm 3 rotates in the reverse direction, and then the leather grasping mechanism 30 is moved to the lower part of the leather separating mechanism 20. The suction cup assembly 4 releases, so that the leather is located on the leather grasping mechanism 30. Then, while the leather grasping mechanism 30 is operating, it moves to the flattening mechanism 40. The leather will be flattened on the flattening mechanism 40 under the operation of the leather grasping mechanism 30 and the flattening mechanism 40, and finally it is sent into the processing structure 50 for processing and cutting.

[0041] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
