The utility model replaces the MOPA laser cleaning and manual cleaning methods, thoroughly saves labor costs, and improves the automation of the battery equipment assembly line process.

[0004] The above and the prior art have the following defects: When laser cleaning the battery terminal, since the battery terminal is directly placed on the surface of the housing, it is easy to shake during cleaning, resulting in the offset of the battery terminal on the surface of the housing. The offset of the battery terminal may cause the laser to not act uniformly on its surface, and there may still be dirt or oxides in some parts.

[0005] Therefore, a laser cleaning device for battery terminals is proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the defect that the offset of the battery terminal may cause the laser to not act uniformly on its surface, and a laser cleaning device for battery terminals is proposed.

[0008] The effect achieved by the above-mentioned components is: by setting a limiting structure, it is convenient to limit the negative electrode post and the positive electrode post of the battery placed on the surface of the shell, thereby avoiding the displacement of the negative electrode post and the positive electrode post of the battery during laser cleaning, thereby improving the cleaning effect of the negative electrode post and the positive electrode post of the battery.

[0009] Preferably, one end of the latch is fixedly connected to a rope, and one end of the rope away from the latch is fixedly connected to the frame.

[0010] The effect achieved by the above components is that the bolt will pull the rope when it moves, and the rope reaches a position that limits the bolt, thereby preventing the bolt from being lost after it escapes from the round hole.

[0011] Preferably, a spring is sleeved on the surface of the rectangular rod, and two ends of the spring are fixedly connected to the bracket and the pressure plate respectively.

[0012] The effect achieved by the above components is that the pressure plate will move towards the shell with the help of the contraction force of the spring, and the spring further facilitates the pressure plate to limit the position of the negative electrode column and the positive electrode column of the battery.

[0013] Preferably, a protective pad is fixedly connected to one side of the pressure plate close to the shell, and the protective pad is made of rubber.

[0014] The effect achieved by the above components is that the pressure plate drives the protective pad to fit tightly on the surface of the negative electrode column and the positive electrode column of the battery, and the protective pad prevents the pressure plate from directly squeezing the positive electrode column and the negative electrode column of the battery and causing wear.

[0015] Preferably, a shielding structure is provided on the surface of the shell, and the shielding structure includes a rotating shaft, which is rotatably connected to the surface of the shell, and a baffle is fixedly connected to the arc surface of the rotating shaft, and a threaded rod is threaded through the surface of the baffle.

[0016] The effects achieved by the above components are as follows: By setting the shielding structure, it is convenient to cover the position of the liquid injection hole, thereby preventing dust from entering the shell through the liquid injection hole when not in use, and further avoiding the effect of dust affecting the normal operation of the equipment in the shell.

[0017] Preferably, a slide rail is fixedly connected to the surface of the shell, and a round rod is slidably connected to the inner wall of the slide rail. The round rod is fixedly connected to the surface of the baffle.

[0018] The effects achieved by the above components are as follows: The baffle will drive the round rod to slide along the inner wall of the slide rail. The slide rail restricts the moving path of the round rod, and further restricts the rotation angle of the baffle, so that the baffle and the funnel can be quickly rotated to the appropriate position.

[0019] Preferably, an extension plate is fixedly connected to one side of the baffle. A funnel is fixedly connected to the side of the extension plate away from the baffle. The size of the funnel is adapted to the size of the liquid injection hole.

[0020] The effects achieved by the above components are as follows: Rotate the baffle. The rotation of the baffle will drive the rotation of the extension plate. The rotation of the extension plate will drive the rotation of the funnel. The rotation of the funnel will move towards the direction close to the liquid injection hole until the funnel is communicated with the liquid injection hole, so as to facilitate adding liquid into the shell through the liquid injection hole.

[0022] 1. In the present utility model, by setting the limiting structure, the negative electrode pole column and the positive electrode pole column of the battery are placed on the surface of the shell, and then the rectangular rod is pressed. The pressing plate will move towards the direction close to the shell. When the pressing plate moves to the appropriate position, the pressing plate will closely fit on the surfaces of the negative electrode pole column and the positive electrode pole column of the battery. Then the pin is pressed, and the pin will be inserted into the round hole. The pin restricts the position of the rectangular rod, and further restricts the positions of the negative electrode pole column and the positive electrode pole column of the battery, so as to avoid the offset of the negative electrode pole column and the positive electrode pole column of the battery during laser cleaning, and further improve the cleaning effect on the negative electrode pole column and the positive electrode pole column of the battery.

[0023] 2. In the present utility model, by setting the shielding structure, rotate the baffle. The baffle will drive the rotating shaft to rotate on the surface of the shell. When the baffle moves to the appropriate position, the baffle will cover the liquid injection hole. Then rotate the threaded rod, and the threaded rod will move towards the direction close to the shell by means of the thread. When the threaded rod moves to the appropriate position, the threaded rod will abut against the surface of the shell. The threaded rod restricts the position of the baffle, so as to prevent dust from entering the shell through the liquid injection hole when not in use, and further avoid the effect of dust affecting the normal operation of the equipment in the shell.

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0032] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0033] Such as Figure 1 - Figure 2As shown, the utility model provides a battery pole laser cleaning device, including a shell 1, an explosion-proof valve 2 is installed on the surface of the shell 1, a laser coder 3 is installed on the surface of the shell 1, a liquid injection hole 4 is opened on the surface of the shell 1, a battery negative pole 5 is installed on the surface of the shell 1, a battery positive pole 6 is installed on the surface of the shell 1, and a limiting structure 7 is provided on the surface of the shell 1. By setting the limiting structure 7, it is convenient to limit the battery negative pole 5 and the battery positive pole 6 placed on the surface of the shell 1, so as to avoid the negative pole 5 and the positive pole 6 of the battery from being offset during laser cleaning, thereby improving the effect of cleaning the negative pole 5 and the positive pole 6 of the battery. The surface of the shell 1 is provided with a shielding structure 8, and by setting the shielding structure 8, it is convenient to cover the position of the liquid injection hole 4, thereby preventing dust from entering the shell 1 from the liquid injection hole 4 when not in use, thereby preventing dust from affecting the normal operation of the equipment in the shell 1.

[0034] The specific arrangement and function of the limiting structure 7 and the shielding structure 8 will be described in detail below.

[0035] like Figure 3 and Figure 4 As shown, the limiting structure 7 includes two brackets 71, both of which are fixedly connected to the surface of the housing 1, a rectangular rod 72 is slidably penetrated on the surface of the bracket 71, and a pressure plate 73 is fixedly connected to the end of the rectangular rod 72 close to the housing 1, a frame 74 is fixedly connected to the surface of the bracket 71, and a latch 75 is slidably penetrated on the surface of the frame 74, and a plurality of round holes 76 are opened on the surface of the rectangular rod 72, and the size of the round hole 76 matches the size of the latch 75. A rope 77 is fixedly connected to one end of the latch 75, and the end of the rope 77 away from the latch 75 is fixedly connected to the frame 74. When the latch 75 moves, it will pull the rope 77, and the rope 77 reaches the position of limiting the latch 75, thereby preventing the latch 75 from slipping out of the round hole 76 and being lost. The surface of the rectangular rod 72 is covered with a spring 78, and the two ends of the spring 78 are fixedly connected to the bracket 71 and the pressure plate 73 respectively. The pressure plate 73 will move toward the direction close to the housing 1 with the help of the contraction force of the spring 78. The spring 78 further facilitates the pressure plate 73 to limit the position of the negative battery pole 5 and the positive battery pole 6. The side of the pressure plate 73 close to the housing 1 is fixedly connected with a protective pad 79, which is made of rubber. The pressure plate 73 will drive the protective pad 79 to fit closely on the surface of the negative battery pole 5 and the positive battery pole 6. The protective pad 79 can prevent the pressure plate 73 from directly squeezing the positive battery pole 6 and the negative battery pole 5. Wear occurs.

[0036] like Figure 5 and Figure 6As shown, the shielding structure 8 includes a rotating shaft 81, which is rotatably connected to the surface of the housing 1, and a baffle 82 is fixedly connected to the arc surface of the rotating shaft 81, and a threaded rod 83 is threadedly penetrated through the surface of the baffle 82. A slide rail 84 is fixedly connected to the surface of the housing 1, and a round rod 85 is slidably connected to the inner wall of the slide rail 84. The round rod 85 is fixedly connected to the surface of the baffle 82, and the baffle 82 drives the round rod 85 to slide along the inner wall of the slide rail 84. The slide rail 84 reaches the limit of the moving path of the round rod 85, and then limits the rotation angle of the baffle 82, so that the baffle 82 and the funnel 87 can be quickly rotated to a suitable position. An extension plate 86 is fixedly connected to one side of the baffle 82, and a funnel 87 is fixedly connected to the side of the extension plate 86 away from the baffle 82. The size of the funnel 87 is adapted to the size of the injection hole 4. When the baffle 82 is rotated, the extension plate 86 is driven to rotate, and the extension plate 86 is driven to rotate. The funnel 87 is driven to rotate toward the injection hole 4 until the funnel 87 is connected to the injection hole 4, thereby facilitating the addition of liquid from the injection hole 4 into the shell 1.

[0037] The overall working principle is that when it is necessary to limit the battery pole placed on the surface of the shell 1 for laser cleaning, first pull the pin 75, the pin 75 moves and slides in the frame 74 and gradually comes out of the round hole 76, the pin 75 pulls the rope 77 when moving, and the rope 77 reaches the position of limiting the pin 75, thereby preventing the pin 75 from being lost after coming out of the round hole 76, when the pin 75 comes out of the round hole 76, pull the rectangular rod 72, the rectangular rod 72 slides in the bracket 71, and the movement of the rectangular rod 72 drives the pressure plate 73 to move away from the shell 1, and the pressure plate 73 compresses the spring 78 when moving, and the spring 78 is in a stretched state, and then the negative electrode 5 of the battery and the positive electrode of the battery are connected. The electrode 6 is placed on the surface of the shell 1, and then the rectangular rod 72 is released. The pressure plate 73 will move towards the direction close to the shell 1 with the help of the contraction force of the spring 78. The spring 78 further facilitates the pressure plate 73 to limit the position of the negative battery electrode 5 and the positive battery electrode 6. When the pressure plate 73 moves to a suitable position, the pressure plate 73 will drive the protective pad 79 to fit tightly against the surface of the negative battery electrode 5 and the positive battery electrode 6. The protective pad 79 can prevent the pressure plate 73 from directly squeezing the positive battery electrode 6 and the negative battery electrode 5 and causing wear. Then, the pin 75 is pressed, and the pin 75 is inserted into the circular hole 76. The pin 75 limits the position of the rectangular rod 72, thereby limiting the position of the negative battery electrode 5 and the positive battery electrode 6.

[0038] When it is necessary to cover the liquid injection hole 4, first rotate the threaded rod 83. The rotation of the threaded rod 83 will cause it to move within the baffle 82 by means of the thread. The movement of the threaded rod 83 will move away from the housing 1. When the threaded rod 83 moves to a suitable position, rotate the baffle 82. The baffle 82 will drive the rotating shaft 81 to rotate on the surface of the housing 1. The baffle 82 will drive the round rod 85 to slide along the inner wall of the slide rail 84. The slide rail 84 restricts the movement path of the round rod 85, thereby restricting the rotation angle of the baffle 82, so that the baffle 82 and the funnel 87 can be quickly rotated to a suitable position. When the baffle 82 moves to a suitable position, the baffle 82 will cover the liquid injection hole 4. Then rotate the threaded rod 83. The threaded rod 83 will move towards the housing 1 by means of the thread. When the threaded rod 83 moves to a suitable position, the threaded rod 83 will abut against the surface of the housing 1. The threaded rod 83 restricts the position of the baffle 82. When it is necessary to add liquid into the housing 1 through the liquid injection hole 4, rotate the threaded rod 83. The rotation of the threaded rod 83 will cause it to move within the baffle 82 by means of the thread. The movement of the threaded rod 83 will move away from the housing 1. When the threaded rod 83 moves to a suitable position, rotate the baffle 82. The rotation of the baffle 82 will drive the extension plate 86 to rotate. The rotation of the extension plate 86 will drive the funnel 87 to rotate. The rotation of the funnel 87 will move towards the liquid injection hole 4 until the funnel 87 communicates with the liquid injection hole 4. Then rotate the threaded rod 83. The threaded rod 83 will move towards the housing 1 until the threaded rod 83 tightly abuts against the surface of the housing 1.
