[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-7 , an embodiment provided by the present utility model:

[0025] The bushing of the punching mechanism of the carrier tape production equipment is replaced with a needle roller bearing, which includes a transmission swing arm 1. The surface of the transmission swing arm 1 is movably connected with a first needle roller bearing 2 for connecting the transmission swing arm 1 and the swing arm rotating shaft 3. The first needle roller bearing 2 overcomes the static friction through rolling. The surface of the transmission swing arm 1 is rotatably connected with a swing arm rotating shaft 3, so that the transmission swing arm 1 can be driven to swing by the movement of the cam. The surface of the swing arm rotating shaft 3 is movably connected with a second needle roller bearing 4 for connecting the transmission swing arm 1 and the swing arm rotating shaft 3. The second needle roller bearing 4 overcomes the static friction through rolling. The surface of the transmission swing arm 1 is rotationally connected with a rotating button 5 through damping, which is used to drive the ball valve 6 to rotate, thereby controlling the oil output of the lubricating oil tank 8. The surface of the rotating button 5 is fixedly connected with a ball valve 6 for controlling the oil output of the lubricating oil tank 8. The surface of the ball valve 6 is provided with an oil outlet 7 for the circulation of the lubricating oil. The interior of the transmission swing arm 1 is provided with a lubricating oil tank 8 for storing lubricating oil, which is convenient to flow into the connection between the first needle roller bearing 2 and the swing arm rotating shaft 3 and the connection between the swing arm rotating shaft 3 and the second needle roller bearing 4 through the flow groove 10. A collecting groove 9 is opened inside the transmission swing arm 1 for accumulating lubricating oil and then flowing into the two groups of flow grooves 10. The interior of the transmission swing arm 1 is fixedly connected with a flow groove 10 for allowing the lubricating oil to flow into the connection between the first needle roller bearing 2 and the swing arm rotating shaft 3 and the connection between the swing arm rotating shaft 3 and the second needle roller bearing 4. A sponge 11 is arranged inside the flow groove 10, which can not only filter impurities in the lubricating oil but also prevent too much lubricating oil from flowing out at one time, causing waste and affecting the movement between the first needle roller bearing 2 and the swing arm rotating shaft 3.

[0026] Further, the first needle roller bearing 2 is arranged on one side of the transmission swing arm 1 for connecting the transmission swing arm 1 and the swing arm rotating shaft 3. The second needle roller bearing 4 is arranged on the side of the transmission swing arm 1 away from the first needle roller bearing 2, connecting the transmission swing arm 1 and the swing arm rotating shaft 3 from the other side. The static friction generated by the swing of the transmission swing arm 1 is overcome by both the first needle roller bearing 2 and the second needle roller bearing 4. The first needle roller bearing 2 is movably connected to the surface of the swing arm rotating shaft 3. When the transmission swing arm 1 swings, the needle rollers in the first needle roller bearing 2 connected to the transmission swing arm 1 are driven to rotate, overcoming the static friction generated therein.

[0027] Further, the transmission swing arm 1 is rotatably connected to the surface of the swing arm rotating shaft 3 through the first needle roller bearing 2. The cam acts on the surface of the transmission swing arm 1, causing the transmission swing arm 1 to swing on the swing arm rotating shaft 3. The transmission swing arm 1 is rotatably connected to the surface of the swing arm rotating shaft 3 through the second needle roller bearing 4. The cam acts on the surface of the transmission swing arm 1, causing the transmission swing arm 1 to swing on the swing arm rotating shaft 3, enabling the transmission swing arm 1 to follow the movement of the cam system.

[0028] Further, the rotary button 5 is rotatably connected to the surface of the lubricating oil tank 8. By rotating the rotary button 5, the ball valve 6 can be driven to rotate. The ball valve 6 is rotatably connected to the surface of the lubricating oil tank 8 through the rotary button 5. When the ball valve 6 rotates, the oil outlet 7 can be connected to the outlet on the lubricating oil tank 8, so that the lubricating oil inside the lubricating oil tank 8 flows out from the oil outlet 7.

[0029] Further, the oil outlet 7 is connected to the collection tank 9 through a passage. The lubricating oil flows out from the oil outlet 7 and reaches the collection tank 9, where it accumulates. The collection tank 9 is connected to the flow-through tank 10 through a passage. When the outflow of the lubricating oil gradually increases, the lubricating oil can flow into the two groups of flow-through tanks 10 and then reach the connection between the first needle bearing 2 and the swing arm rotating shaft 3 and the connection between the swing arm rotating shaft 3 and the second needle bearing 4.

[0030] Further, the two groups of flow-through tanks 10 are symmetrically distributed on both sides of the collection tank 9 and act on the surfaces of the first needle bearing 2 and the second needle bearing 4. The two groups of sponges 11 are symmetrically distributed on both sides of the collection tank 9 and are arranged in the two groups of flow-through tanks 10. While filtering impurities in the lubricating oil, they prevent the oil outflow from being too large and affecting the movement between the transmission swing arm 1 and the swing arm rotating shaft 3.

[0031] Further, one end of a group of flow-through tanks 10 away from the collection tank 9 is attached to the surface of the second needle bearing 4, and one end of the other group of flow-through tanks 10 away from the collection tank 9 is attached to the surface of the first needle bearing 2. The lubricating oil in the collection tank 9 is divided into two paths and flows through the two groups of flow-through tanks 10, thus acting on the connection between the first needle bearing 2 and the swing arm rotating shaft 3 and the connection between the swing arm rotating shaft 3 and the second needle bearing 4, playing roles such as lubrication and cooling.

[0032] Working principle: When using the transmission swing arm 1, the cam rotates and acts on the surface of the transmission swing arm 1, causing the transmission swing arm 1 to rotate on the surface of the swing arm rotating shaft 3. When the first needle bearing 2 and the second needle bearing 4 swing with the transmission swing arm 1, through the rotation of the needles thereon, the static friction generated during the swing of the transmission swing arm 1 is overcome, making the movement of the transmission swing arm 1 smoother and the swinging movement more precise. After the transmission swing arm 1 is used for a period of time, due to long-term use, the first needle bearing 2 and the second needle bearing 4 are prone to wear, and the temperature at the connection increases due to friction. Therefore, it is necessary to rotate the rotation button 5 so that the lubricating oil in the lubricating oil tank 8 flows into the collection tank 9 through the oil outlet 7, and then flows from the collection tank 9 along the two flow grooves 10 to the connection between the first needle bearing 2 and the swing arm rotating shaft 3 and the connection between the swing arm rotating shaft 3 and the second needle bearing 4, so as to play a role in lubrication and cooling, improve the service life of the first needle bearing 2 and the second needle bearing 4, and the setting of the sponge 11 can filter impurities in the lubricating oil and prevent too much lubricating oil from flowing out at one time, affecting the movement between the transmission swing arm 1 and the swing arm rotating shaft 3. After an appropriate amount of lubricating oil flows out, rotate the rotation button 5 to close the flow of the lubricating oil.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
