[0001] The utility model belongs to the technical field of capacitor manufacturing detection, and particularly relates to a device for detecting the skew of the core package of a capacitor assembly. Background Technique

[0002] As a basic electronic component, capacitors are widely used in various electronic devices. The manufacturing process of capacitors includes multiple steps, and an important link is to insert the capacitor core package into the rubber particles for fixation and encapsulation. The capacitor core package is usually wound with materials such as aluminum foil and electrolytic paper, having a high capacitance and good electrical performance. However, in the actual production process, the problem that the capacitor core package is skewed when inserted into the rubber particles often occurs. This not only affects the appearance quality of the capacitor, but more importantly, it may cause the aluminum foil inside the core package to break, resulting in the capacitor losing its capacitance and becoming a defective product. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a device for detecting the skew of the core package of a capacitor assembly, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A device for detecting the skew of the core package of a capacitor assembly is provided with a U-shaped frame; a conductive sliding rod is movably arranged in the middle of the U-shaped frame, and the conductive sliding rod can move vertically up and down in the middle of the U-shaped frame. An elastic conductive connecting piece is arranged at the upper end of the U-shaped frame, and an electrical signal inductor is connected to the elastic conductive connecting piece; the conductive sliding rod is electrically connected to an electrical signal generator.

[0006] Furthermore, a conductive column is arranged on the U-shaped frame, a through hole is opened in the middle of the conductive column, and the conductive sliding rod can be embedded in the through hole and slide up and down. The electrical signal generator is electrically connected to the side of the conductive column.

[0007] Furthermore, a conductive sheet is connected to the elastic conductive connecting piece, and the electrical signal inductor is electrically connected to the conductive sheet.​​​​​​​​​​​Furthermore, the elastic conductive connecting member may also be conductive rubber, which passes through the insulating bakelite and is connected to the conductive sheet, and the conductive rubber is fixed on the insulating bakelite.

[0012] Furthermore, an upper truncated platform is provided on the upper portion of the conductive sliding rod for limiting the position and preventing the conductive sliding rod 5 from falling downward.

[0013] Furthermore, a lower truncated cone is provided at the lower end of the conductive sliding rod, and a conductive spring II is provided between the lower truncated cone and the conductive column.

[0014] Beneficial effects:

[0015] The utility model provides a device for detecting the skew of the capacitor core package, which can effectively solve the problem of the capacitor core package being skewed when the capacitor core package is inserted into the colloid during the capacitor manufacturing process. The device is provided with a shaped frame, a conductive slide rod, an elastic conductive connector, an electric signal generator, an electric signal sensor and other components to achieve accurate detection of the skew state of the capacitor core package. When the core package is inserted vertically normally, the conductive slide rod will not contact the elastic conductive connector and no electric signal will be output; when the core package is inserted skewed, the conductive slide rod will move upward due to the pressure of the core package, contact the elastic conductive connector, form a circuit, and the electric signal sensor will issue an alarm after receiving the signal, thereby detecting defective products in time. This device not only improves the automation level of capacitor production and ensures product quality, but also reduces the risk of internal aluminum foil breakage caused by the skew of the core package, reducing the production of unqualified products.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As Figure 1-4 shown, a capacitor assembly core package skew detection device is provided with a U-shaped frame 1; a conductive sliding rod 5 is movably arranged in the middle of the U-shaped frame 1, and the conductive sliding rod 5 can move vertically up and down in the middle of the U-shaped frame 1. An elastic conductive connecting member 3 is arranged at the upper end of the U-shaped frame 1, a conductive sheet 33 is connected to the elastic conductive connecting member 3, and the conductive sheet 33 is electrically connected to an electrical signal inductor (not shown in the figure).

[0025] The U-shaped frame 1 is provided with a bottom plate 13, a column 11, and an insulating bakelite 14. The column 11 is fixed to the bottom plate 13, and the insulating bakelite 14 is fixed to the column 11. A conductive column 12 is arranged on the bottom plate 13, and a through hole 121 is opened in the middle of the conductive column 12. The conductive sliding rod 5 can be inserted into the through hole 121 and slide up and down.

[0026] A side through hole 15 is arranged on the side of the bottom plate 13, and the side through hole 15 extends to the conductive column 12. A conductive plug 151 is arranged on the side through hole 15. The conductive plug 151 is inserted into the side through hole 15 and contacts the conductive column 12. The conductive plug 151 is electrically connected to an electrical signal generator (not shown in the figure).

[0027] The elastic conductive connecting member 3 is a conductive spring 31. A conductive bolt 34 is arranged on the conductive spring 31. The conductive bolt 34 passes through the conductive sheet 33 and the insulating bakelite 14 and then is connected to the conductive spring 31 to provide elastic connection and a conduction path.

[0028] An upper frustum 51 is arranged on the upper part of the conductive sliding rod 5 for limiting to prevent the conductive sliding rod 5 from falling downward.

[0029] A lower frustum 52 is arranged at the lower end of the conductive sliding rod 5. A conductive spring II 32 is arranged between the lower frustum 52 and the conductive column 12 to provide a function of quickly resetting the conductive sliding rod 5.

[0030] The electrical signal inductor is a current sensor

[0031] The electrical signal generator is a direct current generator or a low current generator

[0032] Working principle:

[0033] Initial state:

[0034] The conductive sliding rod 5 is in the initial position, there is a gap between the conductive spring 31 of the conductive sliding rod 5, and the conductive spring II 32 between the lower truncated cone 52 and the conductive column 12 is in a natural state; the electrical signal of the electrical signal generator is transmitted to the conductive sliding rod 5 through the conductive plug 151 and the electrical column 12.

[0035] Testing process:

[0036] When the core package 6 is normally inserted vertically into the granule 7, the core package 6 and the granule 7 are in a parallel and tight state. Since there is no skew, the conductive slide bar 5 will not slide upward and contact the conductive spring 31, and the electrical signal on the slide bar 5 will not be transmitted.

[0037] When the core package 6 is inserted into the rubber particle 7 at an abnormal angle, the height of the core package 6 and the rubber particle 7 increases due to the skewed state. The conductive slide rod 5 will move upward under the action of the core package 6, and the conductive slide rod 5 will contact the conductive spring 31. At this time, the electricity on the conductive slide rod 5 will be transmitted to the electric signal sensor through the conductive spring 31, the conductive bolt 34, and the conductive sheet 33. The electric signal sensor senses the electric signal and sends an alarm, indicating that a defective product has been detected.
