Specifically, the guide 243 (rail) is provided on the drive mounting plate 242 in the vertical direction, and the unit mounting plate 244 is slidably connected to the guide 243 (rail) by the slider 245; the main body (cylinder body of the cylinder) of the driving piece 241 is fixed to the driving mounting plate 242, and the output end of the driving piece 241 is connected to the unit mounting plate 244. When the driving member 241 is started, the unit mounting plate 244 can be driven, and the pre-pressing nail unit 1/final pressing nail unit 2 is driven to move along the guide member 243 (guide rail) in the vertical direction, so that the pre-pressing nail unit 1/final pressing nail unit 2 is close to or far away from the battery, and the battery is operated or kept away, so that the battery is conveniently transferred to the next station.
Referring to fig. 5, the first pressing block 11 includes a feeding portion 115 and a pressing portion 116 spliced at one side of the feeding portion 115. The nail feeding channel 111 is arranged on the nail feeding part 115, and the first nail pressing channel 112 is formed at the joint of the nail feeding part 115 and the nail pressing part 116. The staple feeding channel 111 has an outlet end 1110 that meets the first staple pressing channel 112, the outlet end 1110 being rounded. The rounded corners are designed to facilitate the passage of the sealing nail 5 from the nail feeding channel 111 into the first communication channel 113, preventing the sticking. The first press block 11 adopts the mode of splicing the nail feeding part 115 and the nail pressing part 116 to dig out the round angle, and if the round angle is not spliced, the round angle cannot be designed. In a specific embodiment, the cross section of the first pressing nail channel 112 and the cross section of the first communication channel 113 are circular formed by butt joint of two circular arcs, wherein one circular arc is formed on the nail feeding part 115, and the other circular arc is formed on the nail pressing part 116. After the nail feeding part 115 and the nail pressing part 116 are spliced, the two circular arc butt joints are formed, a first nail pressing channel 112 with a circular cross section is formed between the nail feeding part 115 and the nail pressing part 116, and a first communication channel 113 with a circular cross section is formed.
Referring to fig. 4 and 5, the first pressing block 11 is provided with a first pressing pin inlet 1120 opposite to the sealing pin outlet 1130 and communicating with the first pressing pin channel 112, and the first pressing pin inlet 1120 is provided with a first shaft sleeve 15. The first shaft sleeve 15 is provided with a guide channel 150 communicated with the first nail pressing channel 112, and the first nail pressing rod 12 is inserted into the first nail pressing channel 112 from the guide channel 150. The guide channel 150 can provide guide for the insertion of the first pin pressing rod 12, and improve the guide accuracy.
With continued reference to fig. 4 and 5, the first pin pressing rod 12 includes a first rod portion 121 with a larger diameter and a second rod portion 122 with a smaller diameter connected below the first rod portion 121, the second rod portion 122 having a smaller diameter than the first communication channel 113, and the first rod portion 121 having a larger diameter than the first communication channel 113. The first press stud 12 has a thick and thin shape, and is easily broken if the first press stud is too thin, so that the upper end of the first press stud, that is, the first stem 121, is thickened to increase the rigidity of the first press stud to provide protection.
Specifically, in order to stably convey the sealing nail, the diameters of the first pressing nail channel 112 and the first communication channel 113 are matched with the size of the sealing nail 5, so that the sealing nail 5 can flow to the battery liquid injection port along the first communication channel 113, and the position deviation or overturning in the first communication channel 113 can not occur. Because the diameter of the second stem 122 is smaller than the diameter of the first communication channel 113, the second stem 122 can penetrate into the first communication channel 113; since the diameter of the first rod portion 121 is larger than that of the first communication channel 113, if the first pin pressing rod 12 continuously pushes the sealing pin 5 downwards, the first rod portion 121 is blocked by the first communication channel 113 beyond a set stroke, so that the moving distance of the first pin pressing rod 12 is limited, and the use safety of the equipment is ensured.
Similarly, the second pin pressing rod 32 has the same structure as the first pin pressing rod 12, and also includes a first rod portion having a larger diameter and a second rod portion having a smaller diameter connected below the first rod portion. The diameter of the second rod portion of the second staple pressing rod 32 is smaller than that of the second communication passage 313, so the second rod portion of the second staple pressing rod 32 can penetrate into the second communication passage 313; since the diameter of the first rod portion of the second presser bar 32 is larger than the diameter of the second communication passage 313, if the second presser bar 32 is continuously pushed down beyond the set stroke, the first rod portion of the second presser bar 32 is blocked by the second communication passage 313, thereby defining the moving distance of the second presser bar 32.
Referring to fig. 4, a second sleeve 16 extends below the sealing pin outlet 1130, and a first elastic member 17 is disposed at the outlet of the second sleeve 16. The second sleeve 16 extends the first communication channel 113, and can be abutted against the battery liquid injection port and avoid other components on the battery, such as a protruding step, which are close to the battery liquid injection port, and the avoidance is achieved because the second sleeve 16 is relatively slender, if the second sleeve 16 is not provided, the first press nail block 11 is directly abutted against the battery liquid injection port, and the first press nail block 11 is relatively wide, so that the avoidance of other components on the battery, which are close to the battery liquid injection port, is not easy; meanwhile, the second sleeve 16 is made of metal, so that the sealing nails 5 can pass through conveniently, and the staples are reduced; however, the second sleeve 16 made of metal is not suitable to be in direct contact with the battery, and the battery is easily scratched. The first elastic piece 17 is adopted to contact the battery, so that the battery is not easy to damage, a certain buffering effect can be achieved when the pre-pressing nail unit 1 downwards contacts the battery, and the battery is not damaged due to collision with the battery.
With continued reference to fig. 4, the second sleeve 16 is provided with an air outlet 160. The seal nail 5 is blown into the nail feeding passage 111, and the air outlet holes 160 are used for exhausting air, so that the blown air can flow out.
Referring to fig. 9 and 10, the second pressing block 31 is provided with a second pressing rod inlet 3120 opposite to the pressing rod outlet 3130 and communicating with the second pressing rod channel 312, and the second pressing rod inlet 3120 is provided with a third shaft housing 314. The inlet end of the third shaft sleeve 314 is provided with a first sealing member 315, and the joint of the third shaft sleeve 314 and the second press stud 31 is provided with a second sealing member 316. The third sleeve 314 acts as the first sleeve 15, i.e. provides guidance and protection for the pin shaft. The first sealing member 315 can play a role in sealing the second pin pressing rod 32 and the third shaft sleeve 314, so that no external gas permeates when the battery is vacuumized, and the vacuumizing effect is influenced; the second seal 316 can seal the second shank inlet 3120 to further prevent the infiltration of outside air.
Referring to fig. 9, the pin pressing rod outlet 3130 is provided with a fourth shaft sleeve 317, a third sealing member 318 is disposed at a connection portion between the fourth shaft sleeve 317 and the second pin pressing block 31, and a second elastic member 319 is disposed at an outlet of the fourth shaft sleeve 317. The fourth shaft sleeve 317 functions like the second shaft sleeve 16, i.e. extends the second communication channel 313, and can abut against the battery liquid injection port and avoid other parts of the battery, such as a protruding step, near the battery liquid injection port; the third sealing member 318 can seal the connection position of the two parts, and further prevent the penetration of external air; the second elastic member 319 can be attached to the battery liquid inlet for buffering and sealing.
Referring to fig. 4 to 6, the pre-pressing nail unit 1 of the nail inserting mechanism for the liquid injection machine of the present invention is further provided with a nail feeding block 14 mounted on the first nail pressing block 11, wherein the nail feeding block 14 is connected with an external nail feeding mechanism (not shown) for matching with the structure of the external nail feeding mechanism.
