[0039] Referring to Figures 1-11 The present application embodiment proposes a presser foot device 100 for clamping a battery 200, the presser foot device 100 comprising a presser foot body 10 and a rubber body 20, and the specific structure is introduced as follows:
[0040] The material of the presser foot body 10 can be metal, thereby ensuring sufficient strength. The material of the rubber body 20 is rubber, which can be heat-resistant rubber. The rubber body 20 can be a rubber ring.
[0041] In the present embodiment, the rubber body 20 is arranged at one end of the presser foot body 10, and when the presser foot device 100 clamps the battery 200, the rubber body 20 is in contact with the battery 200.
[0042] By the contact between the rubber body 20 and the battery 200, the friction between the rubber body 20 and the battery 200 is large, and the battery 200 is not easy to scratch, so that the battery 200 can be reliably clamped while avoiding scratching the battery 200. Further, the rubber body 20 is arranged at one end of the presser foot body 10, and only the rubber body 20 needs to be replaced after damage, which is convenient to replace and low in cost. Further, the use of the rubber body 20 can also avoid the problem that the welding slag is easily adhered to the surface of the presser foot and fused with the metal presser foot to form a metal boss, which can press and scratch the surface of the battery 200. Further, the use of the rubber body 20 can also avoid the problem that the metal presser foot is prone to thermal deformation during laser welding, which affects the service life.

[0044] The protective sleeve 30 is used to protect the rubber body 20 from being damaged. The protective sleeve 30 is connected with the foot body 10 through the elastic member 40, so that the protective sleeve 30 has a telescopic structure. When the battery 200 is not clamped, the rubber body 20 is completely accommodated in the protective sleeve 30, and when the battery 200 is clamped, the protective sleeve 30 is compressed, so that the rubber body 20 contacts and clamps the battery 200. At the same time, the telescopic structure design of the protective sleeve 30 can also adapt to the length error of the battery 200, and is suitable for the change of the length of the battery 200.
[0045] Further, the protective sleeve 30 is made of metal. The outer side of the protective sleeve 30 is provided with a plurality of uniformly distributed heat dissipation grooves 31. Reliable heat dissipation can be achieved through the heat dissipation grooves 31, so as to avoid that the temperature of the protective sleeve 30 is too high.
[0046] Further, in some embodiments, such as the present embodiment, the foot device 100 further comprises a guide member 50, one end of the guide member 50 is connected with the foot body 10, and the other end of the guide member 50 is slidably connected with the protective sleeve 30. The guide member 50 is used to guide the movement of the protective sleeve 30, so as to ensure that the protective sleeve 30 can reliably move in the set direction.
[0047] Further, both ends of the elastic member 40 are embedded in the protective sleeve 30 and the foot body 10 respectively. For example, both ends of the elastic member 40 are embedded in the blind holes formed on the protective sleeve 30 and the foot body 10 respectively, so as to realize reliable fixation of the elastic member 40 with the protective sleeve 30 and the foot body 10.
[0048] Further, the number of the elastic members 40 is multiple, and the multiple elastic members 40 are uniformly distributed between the protective sleeve 30 and the foot body 10. By arranging multiple elastic members 40, the stability of the telescopic movement of the protective sleeve 30 can be greatly improved.
[0049] Further, the number of the guide members 50 is multiple, and the multiple guide members 50 are uniformly distributed between the protective sleeve 30 and the foot body 10. By arranging multiple guide members 50, the stability of the telescopic movement of the protective sleeve 30 and the accuracy of the guidance can be greatly improved.
[0050] Further, the elastic member 40 is a spring, and the guide member 50 is a guide screw.
[0051] Further, the rubber body 20 is bonded to the presser foot body 10. The bonding facilitates the installation and removal, and the replacement of the rubber body 20 is also convenient.
[0052] Further, in some other embodiments, the rubber body 20 is fixed to one end of the presser foot body 10 by the boss 60 or the clamping groove 70.
[0053] Specifically, one end of the presser foot body 10 is provided with the boss 60, and the rubber body 20 is a rubber ring, which is sleeved on the boss 60. Alternatively, one end of the presser foot body 10 is provided with the clamping groove 70, and the rubber body 20 is clamped in the clamping groove 70.
[0054] Further, the protective sleeve 30 is threadedly connected to one end of the presser foot body 10, and the protective sleeve 30 is wrapped outside the rubber body 20. The protective sleeve 30 is made of metal.
[0055] Understandably, in order to ensure that the rubber body 20 contacts the battery 200 when clamped, the rubber body 20 protrudes from the end surface of the presser foot body 10 and the protective sleeve 30.
[0056] Further, the presser foot body 10 is further provided with the positioning hole 80 and the fixing hole 90 for installation and positioning.
