Description

Technical Field

[0002] Two conductors close to each other with a layer of non-conductive insulating medium in between form a capacitor. With the rapid development of electronic information technology, it has driven the growth of the capacitor industry. There are a wide variety of capacitor types, and most of the capacitors used in digital electronic products are small circular capacitors. During the production process of such capacitors, a production limiting device is usually required to assist workers in pouring electrolytes into the capacitors and installing caps. However, some problems still occur when the existing production limiting devices are actually used;

[0003] For example, the production limiting device for aluminum electrolytic capacitors disclosed in the application number 201811442299.0 includes a bracket, a collection tray, a feeding limiting device, and a pressing device; the bracket is in a "U" shape; rectangular parallelepiped-shaped support plates are formed at the left and right ends of the end faces of a pair of vertical parts of the bracket close to each other; the feeding limiting device includes a pair of symmetrically arranged feeding limiting units; the feeding limiting unit includes an X-shaped feeding support plate; the feeding support plate is intermittently rotated 180 degrees at equal angles on the corresponding support plate; a pair of symmetrically arranged cylindrical blocking and limiting columns are formed at the four corners of the upper end face of the feeding support plate, which has the characteristics of convenient material loading and unloading, high production efficiency, and convenient waste collection. During the transportation of the capacitor housing by the existing capacitor production device, it generally does not have the function of neatly stacking the capacitor housings in a consistent manner, and it is easy to have a situation where the position of the capacitor housing is not good, resulting in the subsequent pouring work not being able to proceed smoothly. When the capacitor production device pours electrolytes into the capacitor housing, it is easy to have a situation where too much electrolyte is poured. The existing adjustment method is relatively complex, and it is easy to have a situation where the electrolyte solidifies. Most of the existing capacitor production devices do not have the function of automatically detecting unqualified products, and additional manpower is still required to detect unqualified products, which affects the work efficiency of workers.

[0004] In view of the above problems, a production limiting device for aluminum electrolytic capacitors that can reduce the defective rate is proposed. Summary of the Invention

[0040] The present invention will be further described below in conjunction with the embodiments.

[0041] Embodiment 1:

[0042] In order to solve the problem that the existing capacitor production equipment generally does not have the function of stacking the capacitor shells in a uniform manner during the transportation of the capacitor shells, and the capacitor shells are easily positioned poorly, resulting in the subsequent filling work not being able to proceed smoothly, the following solution is disclosed.

The other end of the spring 125 is fixedly connected to a limiting plate 126, one side of the limiting plate 126 extends to one side of the conveyor belt 11, and the limiting plate 126 matches the contact strip 124. At this time, the capacitor housing to be processed is placed on the conveyor belt 11, and the conveyor belt 11 is started. When the conveyor belt 11 is started, the winding roller 121 can be driven to rotate. The winding roller 121 can make the winding roller 2 122 rotate through the belt, and the winding roller 2 122 drives the reciprocating wire. The rod 123 rotates so that the contact strip 124 reciprocates inside the connecting box body 12. When the contact strip 124 collides with the limit plate 126, it drives the limit plate 126 to move forward, thereby moving the capacitor housing. When the contact strip 124 is not in contact with the limit plate 126, the limit plate 126 automatically resets under the action of the spring 125, thereby realizing the reciprocating motion of the limit plate 126. At this time, the position correction operation can be continuously performed for the capacitor housing on the conveyor belt 11. The setting of the buffer block 111 can protect the capacitor housing to the greatest extent during the position correction process and avoid damage to the capacitor housing, thereby realizing the function of correcting the position of the capacitor housing during the loading process, and facilitating the smooth progress of subsequent work.

[0043] Embodiment 2:

When the capacitor housing comes to the inside of the placement chamber 13 along the conveyor belt 11, At this time, the motor 132 is started, and the motor 132 drives the connecting rod 133 to rotate, thereby causing the connecting rod 2 134 to rotate. The connecting rod 2 134 drives the collision block 135 to reciprocate inside the fixed box 131. When it collides with the baffle 137, the baffle 137 will move accordingly. At this time, the opening and closing degree of the through port 138 and the connecting hose 145 changes. At this time, the injection head 15 can inject the electrolyte inside the storage barrel 14 into the inside of the capacitor housing through the connecting hose 145. When the collision block 135 is not in contact with the baffle 137, under the action of the spring 2 136 The baffle 137 is reset to close the opening 138, so that the electrolyte will not be wasted. When the connecting rod 133 rotates, the worm 141 rotates to rotate the worm gear 142, and the worm gear 142 drives the stirring rod 143 and the scraping block 144 to rotate. The stirring rod 143 can stir the inside of the storage barrel 14 to prevent solidification.

[0045] Embodiment 3:

[0046] In order to solve the problem that most existing capacitor production devices do not have the function of automatically detecting unqualified products, and additional manpower is required to detect unqualified products, which affects the work efficiency of the staff, the following solution is disclosed. For details, please refer to Figure 6 and Figure 7The interior of the studio 2 is also fixedly connected to a detection chamber 16, and a placement rack 161 is fixedly connected to the interior of the detection chamber 16. A detector 162 is arranged on the inner side of the placement rack 161, and the detector 162 is located on both sides of the conveyor belt 11.

One end is fixedly connected with a threaded rod 166, and the outer side of the threaded rod 166 is threadedly connected with an L-shaped rod 167. The other end of the L-shaped rod 167 is fixedly connected with a protective block 168, and the protective block 168 is slidably connected to the inside of the placement rack 161.

When the detector 162 detects unqualified products, the detector 162 starts the motor 163, and the motor 163 drives the threaded rod 164 and the threaded rod 166 to rotate together. The threaded rod 164 drives the blocking block 165 to move, thereby closing the entrance above the conveyor belt 11.

The qualified capacitor enters the conveyor belt 173 through the push port 171. When a qualified product is detected, the motor 163 starts in reverse, thereby resetting the blocking block 165 and the protective block 168. At this time, the qualified product can enter the next working process along the conveyor belt 11.
