Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a sealing nail separating mechanism. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] With the development of the lithium battery industry, lithium battery equipment is constantly updated and replaced, and the equipment structure is continuously optimized. At present, the nail separation mechanism is prone to malfunction, and nail jamming, nail blockage, and nail falling occur frequently, resulting in low equipment efficiency and affecting production benefits. The nail separation structure adopts a cross-cutting method to switch the nail suction and nail blowing channels. The cross-section is easy to wear and cause the gap to become larger and larger. During the switching back and forth of the sealing nails, it is easy to be stuck, blocked, and nail falling, causing the rubber nails and equipment to be easily deformed and damaged, and cannot be used.

[0004] With the rapid development of the lithium-ion battery industry, lithium battery equipment, as its core production equipment, is constantly updated. In the manufacturing process of lithium batteries, it is necessary to drive the sealing nails into the battery under a certain negative pressure inside the battery shell to provide a certain release space for internal gas production after the battery is sealed. Before nailing the battery, a nail separation mechanism is required to separate the nails from the material tray. The existing nail separation mechanism is prone to problems such as nail jamming, nail blockage and nail drop. Some nail separation mechanisms use a cross-cutting method to switch the nail suction and nail blowing channels. The cross-section of the channel that switches back and forth between the nail outlet of the vibration plate and the nail separation block is prone to wear and causes the gap to become larger and larger. During the switching process of the sealing nails, it is more likely to cause problems such as nail jamming, blockage, nail drop, and nail deformation, which can easily damage the equipment and products. These problems not only lead to a reduction in equipment efficiency, but also seriously affect production benefits. Utility Model Content

[0037] As introduced in the background technology, in the prior art, before nailing lithium batteries, a nail separating mechanism is required to separate the nails from the material tray. The existing nail separating mechanism is prone to problems such as nail jamming, nail blockage and nail falling. In particular, some nail separating mechanisms use a cross-cutting method to switch the nail suction and nail blowing channels. The cross-section is easily worn, resulting in an increasing gap. In the process of switching back and forth between sealing nails, problems such as nail jamming, nail blockage, nail falling and nail deformation are more likely to occur. In order to solve the above technical problems, the utility model proposes a nail separating mechanism for sealing nails.

[0038] A sealant nail separating mechanism, comprising:

[0039] A mounting seat 6, on which a nail passing rod 9 and a nail blowing rod are provided, the nail passing rod 9 and the nail blowing rod pass through the mounting seat 6 and are fixedly connected to the mounting seat 6;

[0040] The support seat 13, the guide nail rod passes through the support seat 13 and is fixedly connected to the support seat 13; the mounting seat 6 and the support seat 13 are arranged in parallel;

[0041] A nail guide rod is provided on the support seat 13, and the nail passing rod 9 and the nail blowing rod penetrate the mounting seat 6 and are fixed on the mounting seat 6, and the nail guide rod penetrates the support seat 13 and is fixed on the support seat 13;

[0042] A push cylinder 1, which is connected to a support seat 13 and is used to drive the support seat 13 to move closer to or away from the mounting seat 6;

[0043] The push cylinder 1 is fixedly connected to the limit plate 2;

[0044] The switching channel cylinder 5 is connected to the limit plate 2, and drives the support seat 13 to move parallel to the mounting seat 6 through the limit plate 2;

[0045] The mounting plate 7, the mounting seat 6, and the switching channel cylinder 5 are all fixedly mounted on the mounting plate 7;

[0046] The nail passing rod 9, the nail blowing rod and the nail guide rod have the same height. The free end of the nail guide rod extends out of the support seat 13 and is arranged opposite to the nail passing rod 9. The other end of the nail guide rod is connected to the vacuum nitrogen conversion valve, which is used to switch between vacuum and high-pressure nitrogen.

[0047] like Figure 1 As shown, one or more embodiments of the present invention disclose a sealant nail separating mechanism, including:

[0048] The mounting seat 6 is fixed on the mounting plate 7. A nail passing rod 9 and two nail blowing rods are installed horizontally through the mounting seat 6. The two nail blowing rods are a first nail blowing rod 11 and a second nail blowing rod 8. The first nail blowing rod 11 and the second nail blowing rod 8 are located at the same height of the mounting seat 6 and are arranged in parallel. The first nail blowing rod 11 and the second nail blowing rod 8 are respectively located on both sides of the nail passing rod 9 and are at the same distance from the nail passing rod 9. One end of the nail passing rod 9 and the nail blowing rod is a free end, and the other end passes through the mounting seat 6 and is connected to the pipeline, wherein the nail passing rod 9 is connected to the nail outlet of the vibration plate, and the nail blowing rod is connected to the delivery pipeline. Through the nitrogen blowing force, it passes through the pipeline and enters the nailing position of the nailing mechanism.

[0049] The support seat 13 is penetrated by two guide nail rods, namely the first guide nail rod 4 and the second guide nail rod 3. One end of the first guide nail rod 4 and the second guide nail rod 3 are both free ends and extend a certain distance from the support seat 13. The other ends of the two guide nail rods pass through the support seat 13 and are respectively connected to the air pipe joints, which are connected to the vacuum nitrogen conversion valve through the air pipe. The distance between the first guide nail rod 4 and the second guide nail rod 3 is equal to the distance between the nail passing rod 9 and the nail blowing rod, and the free ends of the first guide nail rod 4 and the second guide nail rod 3 are respectively opposite to the free ends of the nail passing rod 9 and the nail blowing rod.

[0050] The nail rod 9, the nail blowing rod and the nail guide rod are all hollow tubes, and the inner diameters of the tubes at the free ends of the nail rod 9 and the nail blowing rod are the same, and the outer diameter of the tube body free end of the nail guide rod is slightly smaller than the inner diameters of the tube bodies at the free ends of the nail rod 9 and the nail blowing rod, and the inner diameter of the nail guide rod is equal to the diameter of the root plane of the sealant nail, so that the guide rod forms a relatively sealed structure with the connection between the nail rod 9 and the nail blowing rod. For example, the inner diameter of the tube of the nail blowing rod and the nail rod 9 is 0.1 mm larger than the diameter of the root plane of the nail guide rod and the sealant nail, and the middle through hole of the nail guide rod is vacuumed to absorb the root plane of the sealant nail.

[0051] The pushing cylinder 1 is fixedly installed on the limit plate 2, the support seat 13 is arranged opposite and parallel to the mounting seat 6, the pushing cylinder 1 is connected to the support seat 13 through the first connecting shaft 15, and the support seat 13 is not connected to the limit plate 2. The pushing cylinder 1 drives the connecting shaft to extend and retract to make the support seat 13 close to or away from the mounting seat 6, so that the nail rod 9 is inserted into or away from the nail rod 9 and the nail blowing rod.

[0052] A guide rail slider assembly 14 is provided on the mounting plate 7, and the mounting plate 7 is connected to the limit plate 2 through the guide rail slider assembly 14. The switching channel cylinder 5 is fixedly connected to the mounting plate 7, and the switching channel cylinder 5 is connected to the limit plate 2 through the second connecting shaft 16. The switching channel cylinder 5 drives the connecting shaft to extend and retract to make the support seat 13 move parallel to the mounting seat 6, so as to switch the positions of the air guide rod, the nail blowing rod and the nail passing rod 9.

[0053] The vacuum nitrogen conversion valve connects the vacuum pump and the nitrogen pump, and the conversion of the vacuum and nitrogen in the guide rod is realized respectively through the conversion of the valve.

[0054] The sealant nail separating mechanism also includes a nail box 10, which is arranged between the mounting seat 6 and the support seat 13, and is arranged below the nail guide rod. The length of the nail box 10 is greater than the distance between the two nail blowing rods, and the width is less than the distance between the mounting plate 7 and the mounting seat 6 after the nail guide rod is inserted through the nail rod 9 and the nail blowing rod.

[0055] In one or more other embodiments of the present application, a nail passing rod 9 and a nail blowing rod are provided on the mounting seat 6 , and a nail guide rod is installed on the supporting seat 13 .

[0056] The sealing glue nail nailing mechanism of the utility model is connected to the vibration plate, the nail rod 9 is connected to the nail outlet of the vibration plate through a pipeline, and is installed on the vibration mechanism through a mounting plate 7.

[0057] The sealant nail separation mechanism of the utility model is provided with a second limit block 17 installed on the limit plate 2, and a first limit block 12 is also installed on the mounting plate 7. The limit blocks are used to limit the reciprocating stroke of the push cylinder and the switching channel cylinder to prevent overshoot and ensure accurate positioning. The limit blocks are used to limit the position, control the guide nail rod to accurately correspond to the nail passing rod and the nail blowing rod and connect them, and the guide rail slider ensures accuracy.

[0058] like Figure 1 As shown, when the sealant nail separating mechanism is working, the sealant nail is introduced into the pipe connected to the nail rod 9 through the vibration plate, and at the same time, the switching channel cylinder 5 drives the second connecting shaft 16 to move, so that the first guide nail rod 4 on the support seat 13 moves to the position of the nail rod 9. At this time, the second guide nail rod 3 corresponds to the position of the second blow nail rod 8. Then the push cylinder 1 drives the first connecting shaft 15 to move the support seat 13 close to the mounting seat 6, so that the free ends of the first guide nail rod 4 and the second guide nail rod 3 are respectively inserted into the pipes at the free ends of the nail rod 9 and the second blow nail rod 8. At this time, the vacuum nitrogen conversion valve connected to the first guide nail rod 4 inserted into the nail rod 9 is switched, so that the first guide nail rod 4 is connected to the vacuum pump, and the vacuum pump is turned on to inhale air. The vacuum degree is about 30kpa. At this time, the sealant nail is adsorbed to the free end of the first guide nail rod 4 through the nail rod 9. At the same time, the vacuum nitrogen conversion valve connected to the second guide nail rod 3 inserted into the second nail blowing rod 8 is switched to connect the second guide nail rod 3 to the nitrogen pump. The nitrogen pressure is in the range of 30kPa to 50kPa, and the sealant nails adsorbed on the second guide nail rod 3 enter the second nail blowing rod 8 under the action of air pressure.

[0059] Next, the pushing cylinder 1 drives the first connecting shaft 15 to move the support seat 13 away from the mounting seat 6, so that the free ends of the first guide nail rod 4 and the second guide nail rod 3 are respectively moved out of the nail passing rod 9 and the second nail blowing rod 8, and the switching channel cylinder 5 drives the second connecting shaft 16 to move, driving the first guide nail rod 4 on the support seat 13 to move to the position of the first nail blowing rod 11. At this time, the second guide nail rod 3 corresponds to the position of the nail passing rod 9. Then, the pushing cylinder 1 drives the first connecting shaft 15 to move the support seat 13 close to the mounting seat 6, so that the free ends of the first guide nail rod 4 and the second guide nail rod 3 are respectively inserted into the pipes of the free ends of the first nail blowing rod 11 and the nail passing rod 9, and the cycle is repeated.

[0060] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
