DETAILED DESCRIPTION

[0017] The following will describe the technical solutions in the embodiments of the present invention in detail in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Combination Figure 1-6 As shown, the acid pot degassing needle guide structure 100 includes an upper guide plate 101 and a lower guide plate 102 which are arranged to fit each other up and down, and the upper guide plate 101 and the lower guide plate 102 are slidably arranged therebetween. The upper guide plate 101 includes a plurality of upper guide bars 103 arranged in sequence, and the lower guide plate 102 includes a plurality of lower guide bars 104 arranged in sequence, and each upper guide bar 103 corresponds to a lower guide bar 104. A plurality of upper guide grooves 105 are arranged on one side of the upper guide bar 103, and a plurality of lower guide grooves 106 are arranged on one side of the lower guide bar 104, and each upper guide groove 105 corresponds to a lower guide groove 106. During the guiding, the upper guide bar 103 and the corresponding lower guide bar 104 are close to each other, and the upper guide groove 105 and the corresponding lower guide groove 106 are clamped to form a guide space 107 , and the acid pot venting needle 200 passes through the guide space 107 and is inserted into the battery 300 .

[0019] The illustrated guide space 107 does not show a space that can be passed through due to viewing angle reasons. The space is formed deep in the grooves of the upper guide groove 105 and the lower guide groove 106 .

[0020] In this embodiment, by sliding between the upper and lower guide plates, the upper and lower guide grooves are clamped to form a guide space, and the air needle can be inserted into the battery along the contraction guide of the space to achieve acid injection of the battery. Acid injection of multiple rows of batteries can be achieved at one time, which is efficient and convenient.

[0021] Further, after the guiding is completed, the lower guide bar 104 slides to the lower side of the upper guide bar 103 adjacent to the corresponding upper guide bar 103 .

[0022] In this embodiment, after the guiding is completed, the upper and lower guide bars are separated from each other, and the lower guide bar moves to the bottom of an upper guide bar next to the corresponding upper guide bar, thereby improving the space profit rate and making the structure compact and efficient.

[0023] Furthermore, a sliding groove 108 is formed on the surface of the upper guide plate 101, and a positioning column 109 is formed on the lower guide plate 102, and the positioning column 109 is engaged and slid in the sliding groove 108. There are multiple sliding grooves 108, and there are multiple positioning columns 109 correspondingly, and each positioning column 109 is provided with an anti-separation nut 110.

[0024] In this embodiment, the sliding between the upper and lower guide plates is ensured to be accurate through the positioning function of the positioning column and the sliding groove. The anti-disengagement nut will not screw the two guide plates together. The two guide plates can slide between each other, but due to the guiding function of the positioning column and the sliding groove, they will only slide in a specific direction, thus ensuring the accuracy of the guide space.

[0025] Furthermore, it also includes a driving mechanism, which drives the upper guide plate 101 and the lower guide plate 102 to slide against each other. The driving mechanism includes a cylinder 111, a swing arm 112, an upper connecting rod 113, and a lower connecting rod 114. The swing arm 112 is formed with a swing shaft 115 near the middle. The output end of the cylinder 111 is connected to one side of the swing shaft 115 on the swing arm 112. The two ends of the swing arm 112 are respectively connected to one end of the upper connecting rod 113 and one end of the lower connecting rod 114. The other end of the upper connecting rod 113 is connected to the upper guide plate 101, and the other end of the lower connecting rod 114 is connected to the lower guide plate 102. The lower connecting rod 114 is connected to an L-shaped folding plate 119, which is formed on one side of the lower guide plate 102. All the connections are rotatably connected, and the fixed ends of the swing shaft 115 and the cylinder 111 are installed on the frame.

[0026] In this embodiment, through the output of the cylinder, one output can drive the rotation of the swing arm. The two ends of the swing arm are respectively connected to two connecting rods, and the two connecting rods are respectively connected to the guide plates. Finally, one output can drive the sliding between the two guide plates. The sliding between the two guide plates is limited to a certain range by the sliding groove and the positioning column, which ultimately ensures the accuracy of the guide space.

[0027] Further, the upper connecting rod 113 and the lower connecting rod 114 are connected to the swing arm 112 and are respectively formed with an adjustment slot 116. The upper connecting rod 113 and the lower connecting rod 114 are telescopic rods. They include a mounting seat 117, and a square tube 118 is formed on the upper guide plate 101, and the square tube 118 is slidably mounted on the mounting seat 117.

[0028] In this embodiment, the stroke of the upper and lower guide plates is adjusted by adjusting the long groove on the swing arm, and the stroke increases when the distance from the center of the swing arm increases; the position of the upper and lower guide plates is adjusted by the length of the connecting rod, and the two connecting rods can be screws, and the length adjustment is achieved by adjusting the left and right teeth; the upper guide plate is guided to slide through a mounting seat installed on the frame; the lower guide plate is provided with a positioning column that slides on the sliding groove of the upper guide plate to achieve guidance.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0030] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
