[0031] The existing material transfer mechanism cannot detect the phenomenon that the suction cup fails to pick up the material or the material falls, resulting in unqualified products flowing to the next process.

[0032] Based on this, the first embodiment of the present invention provides a material transfer mechanism, referring to Figure 1 and Figure 2 The material transfer mechanism includes a transfer component 1 and a material picking component 2 installed at the power output end of the transfer component 1, wherein the material picking component 2 includes a suction cup 21 and a proximity switch 22, the suction cup 21 is used to suck up materials, and the proximity switch 22 is used to detect whether there is material on the suction cup 21.

[0033] During operation of the material transfer mechanism provided by the present application, the suction cup 21 is used to absorb material, and the transfer assembly 1 is used to drive the suction cup 21 to move within a space to transfer the material to a designated location. While the suction cup 21 absorbs and transfers the material, the proximity switch 22 emits light toward the material on the suction cup 21, and uses the material's blocking or reflection of the light to detect whether the material is on the suction cup 21. This can alert the staff to promptly inspect and repair the material if the suction cup fails to absorb the material or if the material falls, preventing unqualified products from flowing into the next process.

[0034] As an optional embodiment, the proximity switch 22 is a photoelectric sensor or a laser sensor.

[0035] As an optional embodiment, the proximity switch 22 can be linked to the production line's alarm system. The alarm system, which includes a buzzer and / or warning light, can sound an alarm when the proximity switch 22 detects the absence of material on the suction cup 21 during material transfer, prompting staff to conduct a prompt inspection. Furthermore, the proximity switch 22 can also be linked to the transfer assembly 1. When the proximity switch 22 detects the absence of material on the suction cup 21, the transfer assembly 1 can stop operation and wait for staff to repair it.

[0036] Continue to refer to Figure 1 The transfer component 1 includes an X-axis drive structure 11, a Y-axis drive structure 12 and a Z-axis drive structure 13, wherein: the Y-axis drive structure 12 is slidably connected to the X-axis drive structure 11 along the X-axis direction; the Z-axis drive structure 13 is slidably connected to the Y-axis drive structure 12 along the Y-axis direction; the material picking component 2 is slidably connected to the Z-axis drive structure 13 along the Z-axis direction.

[0037] Specifically, the X-axis drive structure 11 includes an X-axis guide rail and an X-axis motor. The Y-axis drive structure 12 is slidably connected to the X-axis guide rail, and the X-axis motor is used to drive the Y-axis drive structure 12 to slide along the length of the X-axis guide rail. The Y-axis drive structure 12 includes a Y-axis guide rail and a Y-axis motor. The Z-axis drive structure 13 is slidably connected to the Y-axis guide rail, and the Y-axis motor is used to drive the Z-axis drive structure 13 to slide along the length of the Y-axis guide rail. The Z-axis drive structure 13 includes a cylinder, the cylinder body of which is slidably connected to the Y-axis guide rail, and the material removal assembly 2 is mounted on the end of the cylinder piston rod.

[0038] Continue to refer to Figure 2 On the basis of the above structure, there are multiple Z-axis drive structures 13 and multiple groups of material picking components 2. The material picking components 2 correspond one to one and are slidably connected to the Z-axis drive structure 13 along the Z-axis direction.

[0039] In this embodiment, there are two Z-axis drive structures 13 and two groups of retrieving assemblies 2. Each retrieving assembly 2 corresponds to a Z-axis drive structure 13 and is installed at the power output end of the corresponding Z-axis drive structure 13. Multiple retrieving assemblies 2 can be used to pick up multiple materials at once, reducing the number of retrieving operations and thus improving work efficiency.

[0040] Continue to refer to Figure 2 The material removal assembly 2 also includes a suction cup mounting plate 23, which is mounted on the power output end of the transfer assembly 1. The suction cup 21 and proximity switch 22 are both mounted on the suction cup mounting plate 23. In this embodiment, there are multiple suction cups 21; each of the suction cups 21 is fixed to the suction cup mounting plate 23 and spaced apart around the center of the suction cup mounting plate 23. The multiple suction cups 21 enable multi-point suction of the material, preventing it from falling.

[0041] Reference Figure 3The suction end of the suction cup 21 is located below the suction cup mounting plate 23; the proximity switch 22 is fixed to the top of the suction cup mounting plate 23, and a detection through hole 231 is opened on the suction cup mounting plate 23 corresponding to the detection end of the proximity switch 22.

[0042] Specifically, the retrieving assembly 2 also includes a bent plate 24 connected between the proximity switch 22 and the suction cup mounting plate 23. The bent plate 24 is Z-shaped, with its lower end secured to the suction cup mounting plate 23 via screws or other fasteners, and its upper end secured to the proximity switch 22 via nuts or other fasteners. A detection through-hole 231 is provided below the detection end of the proximity switch 22 to block the light emitted by the proximity switch 22.

[0043] Continue to refer to Figure 3 The material picking component 2 also includes several limit shafts 25 and several springs 26. The two ends of the limit shaft 25 are respectively slidably connected to the transfer component 1 and the suction cup mounting plate 23. The springs 26 are respectively mounted on the limit shaft 25, and the two ends of the spring 26 are respectively in contact with the transfer component 1 and the suction cup mounting plate 23.

[0044] When the suction cup 21 absorbs the material, the spring 26 applies pressure to the suction cup 21, so that the suction cup 21 fits tightly with the surface of the material, thereby making the suction cup 21 absorb the material more firmly, alleviating the problem of the suction cup 21 failing to absorb the material and the material falling.

[0045] In this embodiment, there are multiple limiting shafts 25 and springs 26 , which are spaced apart and distributed around the center of the suction cup mounting plate 23 .

[0046] Based on the above structure, the Z-axis drive structure 13 further includes a connecting plate 131, which is fixedly connected to the piston rod end of the cylinder in the Z-axis drive structure 13. The ends of the limit shaft 25 slidably penetrate the connecting plate 131 and the suction cup mounting plate 23, respectively. The ends of the spring 26 abut against the connecting plate 131 and the suction cup mounting plate 23, respectively. The end of the limit shaft 25 that passes through the connecting plate 131 and the end that passes through the suction cup mounting plate 23 are provided with a nut, a shoulder, or a nut to prevent the limit shaft 25 from falling off.

[0047] The second embodiment of the utility model provides a battery cell packaging auxiliary material taking and placing device, referring to Figure 4 The device includes a material storage box 100 and the material transfer mechanism described in any of the above embodiments.

[0048] In the above structure, the transfer assembly 1 is used to drive the material removal assembly 2 to move between the material storage box 100 and the material placement station; the suction cup 21 is used to absorb the material from the material storage box 100 and place it in the battery cell material box on the material placement station, thus realizing the automatic retrieval and placement of battery cell packaging auxiliary materials. During the process of suction cup 21 sucking and transferring materials, the proximity switch 22 can detect the presence of material on the suction cup 21 in real time. If the suction cup does not have material on it, the alarm system will sound an alarm and stop the transfer assembly 1, prompting staff to conduct timely inspection and repair.

[0049] The battery cell packaging auxiliary material taking and placing device has at least all the technical effects of the above-mentioned material transfer mechanism, which will not be repeated here.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
