Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and more specifically, it relates to a device for deburring battery casings. Background Technology

[0002] The outer casing of new energy batteries is a key structural component for the integration and protection of the entire battery system. Some plastic and alloy casings of specific shapes are injection molded. After molding, the edges of the casings after demolding have burrs, which need to be manually polished. However, for the polishing of a large number of casings after demolding, the manual time is too long and the polishing is uneven. A fine machining process is also required, which increases the manufacturing time of the battery casing.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a battery casing burr polishing device in order to achieve a more practical purpose. Utility Model Content

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a battery casing burr polishing device, including a polishing body 1 with a double-layer box structure. The polishing body 1 is rectangular. Multiple arrayed support seats 2 are rotatably arranged on the polishing body 1. The support seats 2 are rectangular and match the shape of the end of the battery casing. Two positioning blocks are provided on the support seats 2, which are adapted to the positive and negative terminal holes at the end of the battery casing, so as to position the battery casing before it is placed on the support seats 2.

[0026] A reciprocating groove 3 is provided on the grinding body 1 next to each bearing seat 2. A driven shaft 905 is provided in the reciprocating groove 3, and a grinding roller 6 is provided on the top of the driven shaft 905. A track 10 is provided on the inner top wall of the grinding body 1, which surrounds the reciprocating groove 3. A transmission frame 9 is slidably mounted on the track 10. The transmission frame 9 drives the grinding roller 6 to rotate through a drive mechanism. An inner frame 4 is provided in the reciprocating groove 3. A moving path is formed between the inner frame 4 and the grinding body 1. The transmission frame 9 can drive the grinding roller 6 to move on the moving path. The batch of battery shells are placed on each bearing seat 2. When the grinding roller 6 moves in the reciprocating groove 3, it can grind the burrs on the edge of the battery shell, so that the grinding of each battery shell is uniform and more neat.

[0027] The transmission frame 9 is connected to the reciprocating mechanism and moves back and forth within the reciprocating groove 3, such as... Figure 3 and Figure 4 As shown, the reciprocating mechanism includes a sprocket 7, an inner frame 4 is provided in the reciprocating groove 3, and a moving path is formed between the inner frame 4 and the grinding body 1, and the grinding roller 6 moves along the path.

[0028] The inner frame 4 has a linkage shaft 701 rotatably mounted at both ends. Each linkage shaft 701 is equipped with a sprocket 7. The two sprockets 7 are connected by a chain 8. The transmission frame 9 is connected to one of the chain links on the chain 8. One of the linkage shafts 701 passes through the middle layer of the grinding body 1 and is connected to the bottom first motor 11. The first motor 11 drives the chain 8 to move, causing the transmission frame 9 to move along the track 10. The abrasive roller 6 on the transmission frame 9 moves along the path to grind the edge of the battery casing.

[0029] like Figure 2 and Figure 4 As shown, the groove inside the track 10 is smooth, and the top of the transmission frame 9 is provided with a guide head 902. The end of the guide head 902 is spherically slidably locked inside the track 10, so that the transmission frame 9 is limited by the track 10 and slides inside the track 10 with the chain 8.

[0030] The drive mechanism includes a second motor 901 located at the bottom of the transmission frame 9, such as... Figure 4 As shown, a gear 904 connected to a second motor 901 is rotatably installed inside the transmission frame 9. A driven shaft 905 is rotatably connected to the transmission frame 9, and a toothed groove 906 is provided on the circumference of the driven shaft 905. The gear 904 meshes with the toothed groove 906. During the movement of the transmission frame 9, the second motor 901 drives the gear 904 to rotate, and the gear 904 drives the driven shaft 905 and the grinding roller 6 to rotate through the meshing toothed groove 906.

[0031] Throughout the entire movement path of the abrasive roller 6, the width of the reciprocating movement path of the abrasive roller 6 matches the length and width difference of the support seat 2. When the abrasive roller 6 moves on the path close to the support seat 2, it polishes both sides of the battery casing. After the abrasive roller 6 moves to the path away from the support seat 2, the support seat 2 drives the battery casing to rotate 90 degrees so that the two ends of the battery casing correspond to the abrasive roller 6. The abrasive roller 6 continues to move and polishes the two ends of the battery casing until the abrasive roller 6 returns to the initial position, and the polishing work is completed.

[0032] The grinding of the battery casings on multiple support seats 2 is carried out simultaneously and completed at the same time. Figure 3As shown, a steering shaft 14 is provided at the bottom of the bearing seat 2. The steering shaft 14 passes through the top and middle layers of the grinding body 1 and is rotatably connected to the bottom of the grinding body 1. A worm gear 15 is provided on the steering shaft 14 in the lower space of the grinding body 1. A main shaft 12 is transversely inserted inside the grinding body 1, and one end of the main shaft 12 is connected to the main motor 5 on the outside of the grinding body 1. A worm 13 is provided on the main shaft 12 corresponding to the bottom of each bearing seat 2. The worm 13 meshes with the corresponding worm gear 15. The main motor 5 drives the main shaft 12 to rotate, so that multiple worm gears 15 and worm 13 cooperate simultaneously, driving multiple bearing seats 2 to rotate and turn simultaneously. The start and stop times are set and the operation is realized by an external controller. The design involving the prior art will not be described in detail.

[0033] This device can polish multiple battery casings simultaneously, resulting in more uniform and efficient polishing.
