[0025] This embodiment relates to a clamping mechanism for clamping products 50 in a stacked state, as shown in the figure. Figs. 1-3 The clamping unit includes a clamping base 10 and a first clamping jaw 20 and a second clamping jaw 30 slidably disposed on the clamping base 10. The first clamping jaw 20 and the second clamping jaw 30 are arranged opposite to each other, and together they form a clamping space 40 for clamping the product 50. The two opposite ends of the clamping space 40 are a feeding end 41 and a pressing end 42, respectively. A pressing assembly 60 is provided on the clamping base 10. The pressing assembly 60 includes a pressing block 61 disposed at the pressing end 42. The pressing block 61 is used to abut against the top of the stacked product 50. During clamping, the pressing block 61, the first clamping jaw 20 and the second clamping jaw 30 cooperate to clamp the stacked product 50.
[0026] In addition, the clamping mechanism also includes a robot arm 70, which is a six-axis robot arm 70. The clamping seat 10 is fixedly installed on the robot arm 70. By driving the robot arm 70 to move, the clamping seat 10 is driven to move, thereby realizing the clamping, conveying and stacking of the stacked products 50.
[0027] During clamping, the manipulator 70 drives the clamping seat 10 to move to the stacked product 50. By pointing the feed end 41 of the clamping space 40 downward, the stacked product 50 enters the clamping space 40 from the feed end 41. At this time, the pressing block 61 abuts against the top of the stacked product 50 to press the stacked product 50. Then, by driving the first gripper 20 and the second gripper 30 to slide relative to each other, the stacked product 50 is clamped. Then, the manipulator 70 drives the clamping seat 10 to move, thereby realizing the clamping, conveying and stacking operation of the product 50.
[0028] Furthermore, the pressing assembly 60 also includes a fixed base 62 and an elastic element fixedly disposed on the clamping base 10. The pressing block 61 is elastically connected to the fixed base 62 through the elastic element. The elastic element is used to provide elastic force to the pressing block 61 so that the pressing block 61 can press against the top of the stacked product 50.
[0029] The elastic element provides elastic force to the pressure block 61, enabling the pressure block 61 to automatically adjust its position according to the height difference of the stacked products 50 (battery cover products 50), and press the products 50 tightly, thereby achieving stable clamping of the stacked pile products 50 and improving the stability and reliability of the clamping of the first gripper 20 and the second gripper 30.
[0030] Furthermore, referring to Fig. 2 and Fig. 3 The elastic element includes a pressure spring 63 disposed between the fixed seat 62 and the pressure block 61, with one end of the pressure spring 63 abutting against the fixed seat 62 and the other end abutting against the pressure block 61.
[0031] The pressure spring 63 enables the pressure block 61 to automatically adjust its position according to the height of the product 50, providing appropriate clamping force and avoiding unstable clamping due to differences in the height of the product 50, thus ensuring that there is less chance of missing or dropping material during clamping and conveying.
[0032] Furthermore, the pressing assembly 60 also includes a guide post 64, which is disposed between the fixed base 62 and the pressing block 61. One end of the guide post 64 is fixedly connected to the fixed base 62, and the other end of the guide post 64 extends along the length direction of the clamping space 40. The pressing block 61 is slidably connected to the guide post 64, and the pressing spring 63 is wrapped around the guide post 64.
[0033] In this embodiment, there are four guide posts 64, which are rectangularly distributed on the fixed base 62. There are two pressure springs 63, which are respectively wound around two of the guide posts 64. In other embodiments, the number and distribution of the guide posts 64 can be increased or decreased according to the actual situation. Similarly, the number of pressure springs 63 can also be adjusted accordingly.
[0034] By setting the guide post 64, the pressure block 61 can slide between the fixed base 62 and the first clamp 20 and the second clamp 30, so that the pressure block 61 can better adapt to the height difference of the stacked products 50 during the clamping process. At the same time, the pressure block 61 is always subjected to the elastic force of the pressure spring 63, thereby ensuring that the pressure block 61 can press against the top of the stacked products 50.
[0035] Furthermore, referring to Fig. 2 and Fig. 3The clamping mechanism also includes a driving component for driving the first gripper 20 and the second gripper 30 to slide in a direction that is closer to or further away from each other. The driving component is a double slider cylinder 80. The double slider cylinder 80 includes a cylinder body 81 and two symmetrically arranged sliders 82. The two sliders 82 can slide relative to each other. The first gripper 20 and the second gripper 30 are respectively fixedly connected to the two sliders 82.
[0036] It should be noted that the double slider cylinder 80 is a well-known technical means in the field and is not the inventive point of this application, so it will not be described in detail here.
[0037] During operation, by controlling the air pressure change in the dual-slider slide cylinder 80, the two sliders 82 are driven to slide relative to each other, thereby causing the first gripper 20 and the second gripper 30 to move toward each other or away from each other, so as to clamp and release the stacked product 50.
[0038] By employing a dual-slider cylinder 80 as the driving component, the clamping mechanism of this application can ensure clamping force while also achieving precise control of the clamping action, preventing the battery cover product 50 from falling off during transfer, and improving the efficiency and stability of stacking and encoder.
[0039] Furthermore, referring to Fig. 2 and Fig. 3 The clamping mechanism also includes a guide assembly 90 for guiding the first gripper 20 and the second gripper 30 to move toward each other or away from each other. There are two sets of guide assemblies 90, and the two sets of guide assemblies 90 are symmetrically arranged on two opposite sides of the clamping seat 10.
[0040] Specifically, the guide assembly 90 includes a guide rail 91 disposed on the clamping seat 10 and a first guide block 92 and a second guide block 93 slidably disposed on the guide rail 91. The guide rail 91 is disposed along the sliding direction of the first gripper 20 and the second gripper 30. The first guide block 92 and the second guide block 93 can slide relative to the guide rail 91 in a direction that approaches or moves away from each other, and the first guide block 92 and the second guide block 93 are respectively fixedly connected to the first gripper 20 and the second gripper 30.
[0041] By setting the guide rail 91, the first guide block 92 and the second guide block 93, the first gripper 20 and the second gripper 30 can slide along the guide rail 91, thereby achieving movement that moves closer or further away from each other, further improving the smoothness of movement of the first gripper 20 and the second gripper 30.
[0042] Furthermore, each of the first gripper 20 and the second gripper 30 has an abutment flange 21 on its opposite side for abutting against the bottom side of the stacked product 50.
[0043] The abutment flange allows the first gripper 20 and the second gripper 30 to abut more firmly against the bottom side of the product 50 when gripping the product 50. In this way, it is ensured that the product 50 will not easily fall off during gripping and movement, thereby improving the stability of gripping and the operating quality of the production line.
[0044] Furthermore, an adhesive layer 22 is provided on the opposite side of the first gripper 20 and the second gripper 30.
[0045] By setting the rubber coating layer 22, on the one hand, the clamping friction can be increased to ensure the clamping stability; on the other hand, the rubber coating layer 22 can effectively prevent the first gripper 20 and the second gripper 30 from damaging the product 50.
[0046] In addition, this application also provides a stacking machine with the clamping mechanism described above.
[0047] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
