[0002] With the intelligent development of industrial production, in the production processes of many industries such as thin films and new energy batteries, the transportation and transfer of coiled materials are involved. In the existing technology, a cantilever is often used to grasp and place coiled materials. Currently, the main blocking technology is to manually place a blocking block at the front end of the cantilever by workers. This causes the problem that it cannot meet the high efficiency requirements of modern industry. Secondly, there are problems such as accidental touch, bruising or pinching when workers place the blocking block, and there may also be risks such as the blocking block slipping due to insecure setting during the movement of the cantilever transfer. Therefore, the utility model aims at the problem of manually setting the blocking block in the existing technology, improves the automation level, and focuses on solving the problems of ensuring the safety and convenience of the coiling material loading and unloading process, and preventing the coiled material or the blocking block from falling during the transfer process, resulting in safety accidents.

[0018] In order to disclose in detail the technical solutions provided by the present utility model, the following further introduction is made with reference to the drawings of the specification.

[0019] Combined with Figures 1-3 , a cantilever automatic blocking mechanism provided by the present utility model includes a driving electric cylinder 1, and the driving electric cylinder 1 is configured to drive the rotation of the cam 7, including using a stepping motor or a reduction motor. For better control effects, in some embodiments, a reduction device or mechanism is included to increase the torque and control the rotation speed of the driving electric cylinder. Of course, existing slow driving electric cylinders can also be directly connected. The cam 7 is an eccentric wheel structure, and also includes a structure as Figure 2 shown, and an eccentric column can be fixed on the side of a turntable. A spring 5 is further provided on the blocking block 4, and the other end of the spring 5 is fixedly connected to the mounting body 3.

[0020] Generally speaking, compared with the existing automatic blocking mechanism, the present utility model controls the lifting of the blocking block 4 through the cam 7. The lower end of the blocking block 4 is provided with an upward supporting force by the spring 5, and then is pulled downward by the driving device to compress the spring 5, so that the blocking block 4 retracts into the groove opened on the mounting body 3. For the pulling of the cam 7, the simplest way is to pull the blocking block 4 downward through a steel wire rope. For the present utility model, in order to improve its stability, including the smoothness during the lifting process and meeting the needs of a large cantilever structure, it is more stable to set up through a connecting rod, that is, the present utility model is provided with a lifting guiding mechanism 6.

[0021] A connecting rod is arranged on the blocking block 4, and the connecting rod cooperates with the cam 7 to form a linear reciprocating movement. Specifically, a cross bar is arranged at the bottom of the two connecting rods. As Figure 2 shown, the cross bar is located below an eccentric column on the cam 7. When the cam 7 rotates, the eccentric column presses the cross bar downward, and then the connecting rod drives the blocking block 4 to descend. In order to ensure that the descent is along a straight line and to ensure the setting of the blocking block 4 with a larger size specification, the connecting rod can be arranged in a tube on the fixing plate, and the through tube restricts the side deviation of the connecting rod to ensure a straight movement. Naturally, a certain amount of lubrication can be set. Other embodiments also include structures such as parallel grooves opened on the mounting body 3 to ensure the lifting in the vertical direction.

[0022] As a preferred solution, a lifting detection sensor 2 is also arranged on the mounting body 3. The lifting detection sensor 2 can be an infrared light induction system, mainly to detect whether the blocking block 4 rises normally. On the connecting rod of the blocking block 4, a lifting guiding mechanism 6 is arranged, and the lifting guiding mechanism 6 is arranged on the mounting body 3. In order to realize the automatic docking of the cantilever with the blocking mechanism of the present utility model, a camera 8 is also arranged at the docking position of the mounting body 3 and the cantilever. A positioning block is arranged outside the mounting body 3, and the positioning block is used to fix the cantilever and protect the various functional components on the mounting body 3. A proximity sensor and a driving electric cylinder power supply box assembly are also arranged on the mounting body 3.

[0023] Working principle of the utility model: In industrial production, first, the utility model is docked and installed at the position of the cantilever working end, including fixing the central frame 8. Based on this, the utility model is also combined with an industrial camera to provide accurate docking recognition. After fixation, it is firmly installed through the positioning block on the installation body 3. Start the driving electric cylinder 1, which drives the cam 7 to rotate. Set the working time of the driving electric cylinder 1 to prompt the connecting rod of the blocking block 4 to be pulled down by the eccentric mechanism on the cam 7. At this time, the extended part of the blocking block 4 on the installation body 3 retracts, and the cantilever can easily pass through the central axis of the coil to be grabbed. After the action is completed, the driving electric cylinder 1 is started again. After rotating the driving shaft, the cam 7 rotates, and its eccentric mechanism disengages from the connecting rod of the blocking block 4. Under the action of the spring 5, the blocking block 4 will rise, thereby blocking the coil from slipping. Due to the provision of the lifting guiding mechanism 6, it is ensured that the up-and-down displacement of the blocking block 4 is in a straight-line motion and effectively provides a force to prevent the displacement of the blocking block 4 when bearing the displacement of the coil. After the coil is loaded, the lifting detection sensor 2 starts to work at this time. Only when it can detect that the blocking block 4 has risen successfully can the cantilever be started to work. In this solution, since proximity sensors and other devices are also added to the installation body 3, it is used to ensure that the cantilever avoids collisions with surrounding obstacles during the process of grabbing the coil, loading and unloading operations, and its movement, causing personal injuries and losses.

[0024] As a preferred solution, in addition to the schematic diagram and embodiments given in the utility model, the structure of the cam 7 and the connecting rod of the blocking block 4 in the utility model can also be set as a hinge connection. Start the driving electric cylinder 1 to drive the hinge transmission to complete the action of pulling down the blocking block 4. After stopping work, release the braking control of the driving electric cylinder 1. Under the action of the spring 5, the blocking block 4 is pushed to complete the rising, and the technical effect of the utility model is also achieved.
