Description

Technical Field

[0001] The utility model relates to the technical field of capacitor assembly, in particular to a capacitor cap assembly device. Background Art

[0002] The main body of the cap on the capacitor (such as a car capacitor) is made of plastic and is provided with electrode terminals, which not only play a sealing role, but also play a role in conductive output. The capacitor also includes a shell, which is an aluminum shell. The cap is connected to the opening of the aluminum shell by an interference fit and seals the opening. In the prior art, most of the caps are usually assembled on the aluminum shell by manual pressure. The strength and balance of the manual operation process cannot be controlled, which can easily lead to technical problems such as the cap breaking and causing scrapping and uncontrollable product assembly quality, and the assembly efficiency is low; a small number of manufacturers use cylinders to assemble capacitor caps, refer to CN210549371U, but problems will also arise after the cylinder is operated for a long time. When the air pressure is too high, it will cause the cylinder to extend too much, which will crush the capacitor. In severe cases, it will cause a collision, resulting in damage to the entire assembly device structure. Utility Model Content

[0003] In order to solve the problems mentioned in the background technology, the purpose of the present invention is to provide a capacitor cap assembly device.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0005] The cam is secured to the top of the base with a plurality of springs securing it to the cam, and the cam is secured to the bottom of the base with a plurality of springs securing it to the cam.

[0006] Furthermore, the limiting member is a nut, and the nut is threadedly connected to the top end of the guide rod.

[0007] Furthermore, the elastic member is a compression spring, and each guide rod is sleeved with a compression spring, and two ends of the compression spring respectively contact the lifting seat and the pressure plate.

[0008] Furthermore, the mounting seat is fixed to the base by bolts.

[0009] Furthermore, a switch for controlling the telescopic cylinder is installed on the gantry.

[0010] The beneficial effect of the present invention is that the distance between the bottom end of the screw and the pressure plate can be adjusted accordingly according to the distance between the top end of the capacitor cap and the base after the capacitor cap and the capacitor housing are assembled, so that when the pressure plate just presses the capacitor cap into the capacitor housing, the screw just touches the base and the elastic member will not be compressed. With this arrangement, even if the extension of the telescopic cylinder is too large, the pressure plate cannot continue to move downward under the action of the screw, and the capacitor cap will not be crushed. In addition, the pressure plate will produce relative movement with the lifting seat to avoid the screw from causing a strong impact on the base, thereby avoiding damage to the entire device due to impact.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 are within the scope of protection of the present invention.

[0014] like Figure 1As shown, a capacitor cap assembly device includes a base 1, a gantry 11 is installed on the base 1, a telescopic cylinder 2 is longitudinally installed on the top of the gantry 11, and the telescopic rod of the telescopic cylinder 2 faces the base 1, the telescopic cylinder 2 adopts a pneumatic cylinder, and a switch 9 for controlling the telescopic cylinder 2 is installed on the side beam of the gantry 11, a lifting seat 3 is fixed on the telescopic rod of the telescopic cylinder 2, and two guide rods 41 are longitudinally penetrated in the lifting seat 3, and the bottoms of the two guide rods 41 are commonly connected to a pressure plate 4, and the tops of the guide rods 41 are detachably connected to a limiting member 5, preferably, the limiting member 5 is a nut, and the nut is threadedly connected to the top of the guide rod 41. An elastic member 6 is in contact between the pressure plate 4 and the lifting seat 3. The deformation force of the elastic member 6 is greater than the thrust required to press the capacitor cap into the capacitor housing. Specifically, the elastic member 6 adopts a compression spring. A compression spring is sleeved on each guide rod 41. The two ends of the compression spring are respectively in contact with the base 1 and the pressure plate 4. A mounting seat 7 is fixed to the base 1 by bolts. The position of the mounting seat 7 is set directly below the pressure plate 4. The top of the mounting seat 7 is provided with an accommodating cavity 71 for accommodating the capacitor housing. Two screws 8 are longitudinally penetrated in the pressure plate 4. The screws 8 are threadedly connected to the pressure plate 4. The position of the screws 8 deviates from the mounting seat 7.

[0015] In actual application, the distance between the bottom end of the screw 8 and the pressure plate 4 is adjusted accordingly according to the distance between the top end of the capacitor cap and the base 1 after the capacitor cap and the capacitor housing are assembled, so that when the pressure plate 4 just presses the capacitor cap into the capacitor housing, the screw 8 just touches the base 1, and the elastic member 6 will not be compressed. With this arrangement, even if the extension of the telescopic cylinder 2 is too large, under the action of the screw 8, the pressure plate 4 cannot continue to move downward, and the capacitor cap will not be damaged. In addition, the pressure plate 4 will produce relative movement with the lifting seat 3, avoiding the screw 8 from causing a strong impact on the base 1, thereby avoiding damage to the entire device due to impact. After the telescopic cylinder 2 retracts, the elastic member 6 can reset the pressure plate 4.
