Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a telescopic reel. Background Technology

[0002] Film capacitors are capacitors constructed by overlapping metal foil as electrodes with plastic films such as polyethylene, polypropylene, polystyrene, or polycarbonate at both ends and then winding them into a cylindrical shape. Therefore, the capacitor manufacturing process requires the winding and unwinding of the capacitor core, necessitating the operation of a winding machine's spool. However, traditional winding machines are often equipped with spools made of aluminum and nickel, which are prone to deformation during actual use. Especially when the capacitor core is unwound after winding, the core is easily damaged, causing short circuits and unsightly protrusions, thus affecting production efficiency and yield. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a telescopic roller that flexibly changes the diameter of the support rod, thereby improving the ease of winding capacitor cores and enhancing capacitor production efficiency and yield.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A telescopic reel includes a support rod, a movable part, and a drive assembly. The drive assembly includes the telescopic part, a pneumatic pipe, and a port for connecting a drive device. The telescopic part is connected to the port via the pneumatic pipe. The support rod has a cavity for accommodating the movable part. The outer wall of the cavity has a through hole that mates with the movable part. The movable part reciprocates along the opening direction of the through hole under the drive of the telescopic part. The through holes are evenly distributed on the outer side of the support rod.

[0006] The aforementioned telescopic reel has at least the following beneficial effects: by setting a support rod and a movable part, the movable part can reciprocate along the opening direction of the through hole, thereby quickly and flexibly adjusting the diameter of the support rod, facilitating the fixing and removal of the capacitor core on the support rod, and improving the production efficiency and yield of capacitors; by setting a movable part and a drive assembly, the drive device can stably and accurately drive the movable part through the telescopic part, improving the working stability and control accuracy of the telescopic reel.

[0007] Furthermore, the support rod includes rollers and a connecting part; multiple rollers form a complete shaft; the shaft and the connecting part are coaxially arranged. By setting rollers and a connecting part, the shaft can stably clamp the capacitor core, and the connecting part allows for flexible installation, improving the working stability of the telescopic reel.

[0008] Furthermore, the number of rollers is two, and the cross-sections of the rollers and the telescopic part are semi-circular. This structure ensures that the shaft and the connecting part are coaxially arranged, facilitates the installation and fixing of the support rod, and improves the maintenance convenience of the telescopic roller.

[0009] Furthermore, the nozzle is located at the end of the connecting part away from the roller. This structure facilitates the stable connection of the pneumatic pipe to the drive device through the nozzle, preventing the drive device from failing to fix the telescopic part during the rotation of the support rod, which would affect the working stability of the telescopic roller.

[0010] Furthermore, the connecting part is provided with a support platform, and the roller has a connecting surface on the side away from the through hole; the connecting surface is parallel to the plane where the support platform is located. By providing the support platform and the connecting surface, the connecting part can be quickly installed and fixed, and it is also easy to accurately position and install the connecting part, thereby improving the ease of use of the telescopic roller.

[0011] Furthermore, a notch is provided between the pneumatic pipe and the telescopic part. By providing the notch, the connectivity between the pneumatic pipe and the telescopic part is improved, preventing blockage of the pneumatic pipe from affecting the working stability of the telescopic reel.

[0012] Furthermore, the telescopic part is made of a flexible material, and the opening of the telescopic part is directly opposite the notch. This structure ensures that the telescopic part can quickly drive the movable part to reciprocate under the drive of the drive device, thus ensuring the working stability of the telescopic reel.

[0013] Furthermore, the driving device is an air pump. Air pumps have the advantages of high stability, high precision, and low cost, and using an air pump in the driving device effectively ensures the working stability of the telescopic reel.

[0014] Furthermore, the movable part includes a pushing part located within the cavity and a positioning pin that mates with the through hole. The end of the pushing part away from the positioning pin is attached to the telescopic part. By providing the pushing part and the positioning pin, it is effectively ensured that the positioning pin can reciprocate accurately and stably along the opening direction of the through hole, preventing the movable part from shifting or loosening during movement, and improving the structural stability of the telescopic reel.

[0015] Furthermore, both the upper and lower surfaces of the pushing part are arc-shaped. This structure ensures that the upper and lower surfaces of the pushing part can fit against the inner wall of the telescopic part and the cavity, improving the accuracy of the positioning pin's reciprocating movement along the opening direction of the through hole, and ensuring the connection stability between the support rod and the capacitor core.

[0016] The beneficial effects of the aforementioned telescopic reel are as follows: By incorporating a support rod and a movable part, the movable part can reciprocate along the opening direction of the through hole, thereby quickly and flexibly adjusting the diameter of the support rod. This facilitates fixing and removing the capacitor core from the support rod, improving capacitor production efficiency and yield. Furthermore, the movable part and drive assembly allow the drive device to stably and accurately drive the movable part via the telescopic part, improving the working stability and control precision of the telescopic reel. Finally, the rollers and connecting parts ensure that the shaft can stably clamp the capacitor core, and the connecting parts allow for flexible installation. To improve the working stability of the telescopic reel; by setting up a support platform and connecting surface, the connecting part can be quickly installed and fixed, and can also be accurately positioned and installed, improving the ease of use of the telescopic reel; by setting up a notch, the connectivity between the pneumatic pipe and the telescopic part is improved, and the blockage of the pneumatic pipe is prevented from affecting the working stability of the telescopic reel; by setting up a pushing part and a positioning pin, the positioning pin can be accurately and stably reciprocated along the opening direction of the through hole, preventing the moving part from shifting or loosening during the movement, thus improving the structural stability of the telescopic reel.

[0027] In another embodiment, there are two rollers 120, and the cross-sections of the rollers 120 and the telescopic part 310 are semi-circular. This structure ensures that the shaft 140 and the connecting part 130 are coaxially arranged, and also facilitates the installation and fixing of the support rod 100, improving the maintenance convenience of the telescopic roller.

[0028] In another embodiment, the nozzle 330 is located at the end of the connecting portion 130 away from the roller 120. This structure facilitates the stable connection of the pneumatic pipe 320 to the drive device through the nozzle 330, preventing the drive device from failing to fix the telescopic portion 310 during the rotation of the support rod 100, thus affecting the working stability of the telescopic roller.

[0029] In another embodiment, the connecting part 130 is provided with a support platform 131, and the roller 120 is provided with a connecting surface 121 on the side away from the through hole 111; the connecting surface 121 is parallel to the plane where the support platform 131 is located. By providing the support platform 131 and the connecting surface 121, the connecting part 130 can be quickly installed and fixed, and the connecting part 130 can be accurately positioned and installed, thereby improving the ease of use of the telescopic roller.

[0030] In another embodiment, a notch 321 is provided between the pneumatic pipe 320 and the telescopic part 310. By providing the notch 321, the connectivity between the pneumatic pipe 320 and the telescopic part 310 is improved, and blockage of the pneumatic pipe 320 is avoided, which would affect the working stability of the telescopic reel.

[0031] In another embodiment, the telescopic part 310 is made of a flexible material, and the opening of the telescopic part 310 is directly opposite the notch 321. This structure ensures that the telescopic part 310 can quickly drive the movable part 200 to reciprocate under the drive of the drive device, thus ensuring the working stability of the telescopic scroll.

[0032] In another embodiment, the driving device is an air pump. Air pumps have the advantages of high stability, high precision, and low cost, and using an air pump in the driving device effectively ensures the working stability of the telescopic reel.

[0033] In another embodiment, the movable part 200 includes a pushing part 210 located within the cavity 110 and a positioning pin 220 that engages with the through hole 111. The end of the pushing part 210 away from the positioning pin 220 is attached to the telescopic part 310. By providing the pushing part 210 and the positioning pin 220, it is effectively ensured that the positioning pin 220 can reciprocate accurately and stably along the opening direction of the through hole 111, avoiding displacement or loosening of the movable part 200 during movement, and improving the structural stability of the telescopic scroll.

[0034] In another embodiment, both the upper and lower surfaces of the pressing part 210 are arc-shaped.

[0035] The working principle of this utility model will be further explained below.

[0036] In the use of the telescopic roller in this embodiment, firstly, according to the specifications of the capacitor core, a support rod 100 of the corresponding size is selected so that the inner diameter of the capacitor core's winding core is larger than the outer diameter of the shaft 140, and multiple rollers 120 are assembled into a complete shaft 140; specifically, as shown... Figure 1 As shown, the shaft 140 consists of two semi-circular rollers 120, with the connecting surfaces 121 of the two rollers 120 fitting together. At this time, the drive device is in the off state, and the telescopic scroll is in the position shown... Figure 4In the retracted state shown, the positioning pin 220 is located inside the cavity 110, and the shaft 140 can be easily inserted into the core of the capacitor core. Then, the drive device is activated, causing the drive device, such as an air pump, to supply air to the telescopic part 310 through the port 330, pneumatic pipe 320, and notch 321. After the telescopic part 310 is inflated, it expands outward, pushing the movable part 200 outward. The positioning pin 220 presses against the core of the capacitor core along the opening direction of the through hole 111, increasing the outer diameter of the shaft 140 and fixing the core of the capacitor core. At this time, the telescopic shaft is in the state shown. Figure 5 The telescopic reel is in the expanded state shown; then, the two ends of the telescopic reel are fixed to the winding device via the connecting part 130 and the support platform 131, and the winding operation of the capacitor core is completed by rotating the support rod 100; next, the drive device is turned off, the inflation of air into the telescopic part 310 is stopped, the telescopic part 310 retracts and drives the movable part 200 to move, so that the positioning pin 220 returns to the cavity 110, and the outer diameter of the telescopic reel decreases; at this time, the telescopic reel is in the expanded state shown. Figure 4 In the contracted state shown, since the inner diameter of the capacitor core is larger than the outer diameter of the shaft 140, the capacitor core can be easily pulled out from the shaft 140. This effectively reduces the friction between the telescopic shaft and the film on the capacitor core when the capacitor core is pulled out, preventing the film from being damaged by friction and causing a short circuit in the capacitor core. It also effectively reduces the occurrence of defects such as the film on the capacitor core protruding during transportation, thereby improving the yield of the capacitor.

[0037] As can be seen from the above description, the telescopic reel of this utility model, by setting a support rod 100 and a movable part 200, allows the movable part 200 to reciprocate along the opening direction of the through hole 111, thereby quickly and flexibly adjusting the diameter of the support rod 100. This facilitates fixing and removing the capacitor core on the support rod 100, improving the production efficiency and yield of capacitors. By setting the movable part 200 and the drive assembly 300, the drive device can stably and accurately drive the movable part 200 through the telescopic part 310, improving the working stability and control precision of the telescopic reel. By setting the roller 120 and the connecting part 130, the shaft 140 can stably clamp the capacitor core, and the connecting part 130 can facilitate... Flexible installation improves the working stability of the telescopic reel; the support platform 131 and connecting surface 121 facilitate quick and easy installation and fixation of the connecting part 130, and also facilitate precise positioning of the connecting part 130, improving the ease of use of the telescopic reel; the notch 321 improves the connectivity between the pneumatic pipe 320 and the telescopic part 310, preventing blockage of the pneumatic pipe 320 from affecting the working stability of the telescopic reel; the push part 210 and positioning pin 220 effectively ensure that the positioning pin 220 can move accurately and stably along the opening direction of the through hole 111, preventing displacement or loosening of the moving part 200 during movement, thus improving the structural stability of the telescopic reel.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
