[0023] To enable those skilled in the technical field to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a bacteriostatic outer shell feeding mechanism for a bacteriostatic film assembly machine is used to be installed on an automatic bacteriostatic film assembly machine. The bacteriostatic film assembly machine includes a machine base and a controller. A feeding mechanism and a cam driving device respectively connected to the controller are provided on the machine base, and a product fixture is provided on the feeding mechanism. The bacteriostatic outer shell feeding mechanism is used to convey bacteriostatic outer shells to the product fixture on the feeding mechanism. The bacteriostatic outer shell feeding mechanism includes a vibrating disk 1, a linear vibrator 2, and a shell picking manipulator 3. The vibrating disk 1, the linear vibrator 2, and the shell picking manipulator 3 are respectively connected to the controller. The vibrating disk 1 and the linear vibrator 2 are respectively fixedly installed on the machine base. The output end of the vibrating disk 1 is connected to the input end of the linear vibrator 2. The shell picking manipulator 3 is connected to the output end of the linear vibrator 2. The shell picking manipulator 3 is movably connected to the machine base. The shell picking manipulator 3 is connected to the cam driving device, and the cam driving device can drive the shell picking manipulator 3 to move up and down. The shell picking manipulator 3 is used to grab and place the bacteriostatic outer shell onto the product fixture.

[0025] During the processing, the operator dumps the bacteria-proof outer shell onto the vibrating bowl 1. Through the operation of the vibrating bowl 1, the bacteria-proof outer shell can be orderly conveyed onto the linear vibrator 2, and then through the operation of the linear vibrator 2, the bacteria-proof outer shell is orderly conveyed to the grasping position of the outer shell picking manipulator 3. Through the cooperation of the outer shell picking manipulator 3 and the cam drive device, the bacteria-proof outer shell can be grasped onto the product fixture on the material conveying mechanism, thus realizing the automatic feeding process of the bacteria-proof outer shell. This bacteria-proof outer shell feeding mechanism can automatically feed the bacteria-proof outer shell to the bacteria-proof film assembly machine, thereby improving the automation degree of the equipment and reducing the labor cost; the use of a mechanical structure to achieve automatic feeding can meet the requirements of automated processing, thus improving the processing efficiency.

[0026] As Figure 1 shown, in this embodiment, a pre-positioning component 4 is arranged between the linear vibrator 2 and the outer shell picking manipulator 3. The pre-positioning component 4 is used to receive the bacteria-proof outer shell sent out by the linear vibrator 2 and limit the bacteria-proof outer shell, so that the outer shell picking manipulator 3 can better grasp the bacteria-proof outer shell; the pre-positioning component 4 is respectively connected to the output end of the linear vibrator 2 and the outer shell picking manipulator 3, and the outer shell picking manipulator 3 can grasp the bacteria-proof outer shell from the pre-positioning component 4.

[0027] As Figure 2 shown, specifically, the pre-positioning component 4 includes a pre-positioning fixed seat 41, and the pre-positioning fixed seat 41 is fixedly connected to the machine base. The linear vibrator 2 is provided with an outer shell feeding groove 21. When the linear vibrator 2 works, it can drive the bacteria-proof outer shell to slide along the outer shell feeding groove 21. A material passing groove 42 is arranged at the corresponding position of the pre-positioning fixed seat 41 relative to the outer shell feeding groove 21. The two ends of the outer shell feeding groove 21 are communicated with the output end of the vibrating bowl 1 and the material passing groove 42. Specifically, when working, the vibrating bowl 1 can convey the bacteria-proof outer shell to the outer shell feeding groove 21 in sequence. When the linear vibrator 2 works, it can drive the bacteria-proof outer shell to slide in the outer shell feeding groove 21, so that the bacteria-proof outer shell moves to one end of the outer shell feeding groove 21 close to the pre-positioning fixed seat 41. As the linear vibrator 2 continues to work, the subsequent bacteria-proof outer shell will push the previous bacteria-proof outer shell and push it into the material passing groove 42, so that the bacteria-proof outer shell enters the pre-positioning fixed seat 41.

[0028] The pre-positioning fixing seat 41 is provided with a pre-positioning cylinder 43 and a pre-positioning slider 44. The pre-positioning cylinder 43 is fixedly connected to the pre-positioning fixing seat 41. The pre-positioning slider 44 is slidably connected to the pre-positioning fixing seat 41, and the side wall of the pre-positioning slider 44 is in contact with the pre-positioning fixing seat 41. A pre-positioning groove 45 is provided on the side wall of the pre-positioning slider 44 close to the material passing groove 42. The output end of the pre-positioning cylinder 43 is connected to the pre-positioning slider 44. The pre-positioning cylinder 43 can drive the pre-positioning slider 44 to slide on the pre-positioning fixing seat 41, thereby driving the pre-positioning groove 45 to communicate or be misaligned with the material passing groove 42. In the initial state, the pre-positioning groove 45 is in communication with the material passing groove 42. When the linear vibrator 2 works, it will send the bacteria-proof outer shell into the material passing groove 42 until the subsequent bacteria-proof outer shell sends the previous bacteria-proof outer shell into the pre-positioning groove 45. Then, the pre-positioning cylinder 43 is driven to drive the pre-positioning slider 44 to slide, so as to drive the pre-positioning groove 45 and the bacteria-proof outer shell to move together until the pre-positioning groove 45 is misaligned with the material passing groove 42. At this time, the pre-positioning fixing seat 41 seals one end of the pre-positioning groove 45 close to the material passing groove 42, so that the pre-positioning groove 45 becomes a closed structure, limiting and fixing the bacteria-proof outer shell, which is convenient for the outer shell picking manipulator 3 to pick up the bacteria-proof outer shell from the pre-positioning groove 45, and can reduce the situation of the bacteria-proof outer shell tipping when being picked up, improving the stability of processing. After the outer shell picking manipulator 3 finishes picking up the bacteria-proof outer shell in the pre-positioning groove 45, the pre-positioning cylinder 43 resets and drives the pre-positioning slider 44 to reset until the pre-positioning groove 45 is connected to the material passing groove 42 again for continuous feeding.

[0029] In this embodiment, there are four outer shell feeding grooves 21, four material passing grooves 42 and four pre-positioning grooves 45, and the three are arranged in one-to-one correspondence. By setting four pre-positioning grooves 45, the bacteria-proof outer shell feeding mechanism can simultaneously realize the feeding work of four bacteria-proof outer shells, improving the processing efficiency.

[0030] As Figure 1 shown, a material shortage sensor 22 is installed on the linear vibrator 2. The material shortage sensor 22 is arranged at one end of the linear vibrator 2 close to the vibrating disk 1. The material shortage sensor 22 is connected to the controller and is used to detect whether there is a bacteria-proof outer shell on the linear vibrator 2. The material shortage sensor 22 can detect whether there is a bacteria-proof outer shell on the linear vibrator 2. When the material shortage sensor 22 detects that there is no bacteria-proof outer shell on the linear vibrator 2, it will send a signal to the controller, indicating that the vibrating disk 1 is out of material at this time, so as to remind the operator to replenish the vibrating disk 1 with material in time.

[0031] In this embodiment, the number of the material shortage sensors 22 is four, which are respectively arranged directly above each outer shell feeding groove 21 and can detect whether there is a bacteria-proof outer shell in the corresponding outer shell feeding groove 21. In other embodiments, the number of the material shortage sensors 22 can also be any other number.

[0032] As Figure 3As shown in the figure, the shell material taking manipulator 3 includes a material taking fixed seat 31. The material taking fixed seat 31 is slidably and limit-connected to the machine base. The material taking fixed seat 31 is connected to a cam driving device, and the cam driving device can drive the material taking fixed seat 31 to move up and down. A material taking cylinder 32 is provided on the material taking fixed seat 31. A material taking mounting seat 33 is provided at the output end of the material taking cylinder 32. A material taking jaw cylinder 34 is provided on the material taking mounting seat 33. The material taking cylinder 32 can drive the material taking jaw cylinder 34 to move back and forth between the pre-positioning assembly 4 and the product jig. During processing, after the pre-positioning groove 45 limits the bacteriostatic shell; the material taking cylinder 32 drives the material taking mounting seat 33 to move towards the direction close to the pre-positioning fixed seat 41 until the material taking mounting seat 33 moves directly above the pre-positioning slider 44; then the cam driving device drives the material taking fixed seat 31 and the material taking mounting seat 33 to descend until the material taking jaw cylinder 34 on the material taking mounting seat 33 contacts the bacteriostatic shell on the pre-positioning groove 45, and the bacteriostatic shell is clamped by the material taking jaw cylinder 34; then the cam driving device drives the material taking fixed seat 31 and the material taking mounting seat 33 to rise, so that the material taking jaw cylinder 34 grabs the bacteriostatic shell; then the material taking cylinder 32 drives the material taking mounting seat 33 to move towards the direction close to the product jig until the material taking mounting seat 33 drives the material taking jaw cylinder 34 and the bacteriostatic shell to move directly above the product jig, and then the bacteriostatic shell is placed on the product jig on the material conveying mechanism through the cooperation of the cam driving device and the material taking jaw cylinder 34, completing the feeding work of the bacteriostatic shell.

[0033] In order to limit and guide the movement direction of the material taking mounting seat 33, a material taking slide rail 35 is installed on the material taking fixed seat 31, and the material taking mounting seat 33 is slidably clamped with the material taking slide rail 35. When the material taking cylinder 32 works, the material taking mounting seat 33 will slide on the material taking slide rail 35. Through the cooperation of the two, the movement direction of the material taking mounting seat 33 is limited, ensuring that the material taking mounting seat 33 can drive the material taking jaw cylinder 34 to accurately move to the corresponding position of the pre-positioning fixed seat 41 or the product jig, improving the accuracy of transmission.

[0034] The number of the material taking jaw cylinders 34 is four. The four material taking jaw cylinders 34 are evenly distributed on the material taking mounting seat 33. The four material taking jaw cylinders 34 correspond to the four pre-positioning grooves 45 on the pre-positioning fixed seat 41 one by one, so that the feeding work of four bacteriostatic shells can be completed simultaneously, improving the processing efficiency.

[0035] As Figure 1As shown in the figure, the bacteriostatic shell feeding mechanism further includes a shell detection component 5. The shell detection component 5 is slidably connected to the machine base. The shell detection component 5 is connected to the cam driving device. The cam driving device can drive the shell detection component 5 to move up and down. The shell detection component 5 is used to detect whether there is a bacteriostatic shell on the product fixture. During specific operation, the material conveying mechanism can drive the product fixture to move to the corresponding position of the shell detection component 5. The cam driving device drives the shell detection component 5 to descend, so that the shell detection component 5 contacts the bacteriostatic shell on the product fixture, thereby detecting whether there is a bacteriostatic shell on the product fixture, further judging whether the bacteriostatic shell feeding mechanism has successfully fed the material, and feeding back the detected result to the controller, improving the processing stability and ensuring the qualified rate of the processing of the bacteriostatic film assembly machine.

[0036] Specifically, as Figure 4 shown in the figure, the shell detection component 5 includes a detection fixing seat 51. The detection fixing seat 51 is connected to the cam driving device. A detection head 52 is provided on the detection fixing seat 51. The detection head 52 is arranged corresponding to the product fixture one by one. The detection head 52 is slidably and limit-connected to the detection fixing seat 51. The cam driving device can drive the detection fixing seat 51 to move up and down, and then drive the detection head 52 to move in the direction close to or away from the product fixture. A proximity sensor 53 is provided at the position corresponding to the detection head 52 on the detection fixing seat 51. The proximity sensor 53 is connected to the controller. The proximity sensor 53 is used to detect the position of the detection head 52.

[0037] During specific operation, when the material conveying mechanism transports the product fixture with a bacteriostatic shell to the corresponding position of the shell detection component 5; the cam driving device drives the detection fixing seat 51 to descend, driving the detection head 52 to descend, and the detection head 52 contacts the bacteriostatic shell on the product fixture; pushed by the reaction force of the bacteriostatic shell, the detection head 52 is pushed to rise on the detection fixing seat 51. When the cam driving device drives to the limit position, the bacteriostatic shell on the product fixture will push the detection head 52 to rise to the position corresponding to the proximity sensor 53. At this time, the proximity sensor 53 can detect the detection head 52, indicating that there is a bacteriostatic shell on the product fixture corresponding to the detection head 52. On the contrary, if there is no bacteriostatic shell on the product fixture corresponding to the detection head 52, then the corresponding detection head 52 will not rise to the position corresponding to the proximity sensor 53, and the proximity sensor 53 cannot detect the detection head 52 and will feedback a signal to the controller, indicating that the material has not been successfully fed on this product fixture.

[0038] The bacteria-blocking outer shell feeding mechanism can achieve automatic feeding of the bacteria-blocking outer shell to meet the processing requirements of the automatic bacteria-blocking film assembly machine; moreover, a pre-positioning component 4 is arranged at the front end of the outer shell material-taking manipulator 3, which can ensure that the outer shell material-taking manipulator 3 can smoothly grab the bacteria-blocking outer shell and improve the stability of feeding. On the other hand, by setting the outer shell detection component 5, it can also timely judge whether the feeding on the product fixture is successful, thereby improving the processing yield of the bacteria-blocking film assembly machine and being beneficial to high-quality processing requirements.

[0039] The above specific implementation manners are the preferred implementation manners of the present invention, and do not limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
