Description

Technical Field

[0001] This utility model belongs to the field of capacitor manufacturing technology, and in particular relates to an automatic rejection device for capacitor feed height limit. Background Technology

[0002] Capacitors are common electronic components. Their production involves multiple steps, such as cutting aluminum foil, stapling and winding, impregnation, assembly, sealing, sleeving, and quality inspection. Different production steps require different production equipment, which is connected by conveyor systems. Because defective products are possible during production, the dimensions of the capacitors need to be checked, with height being one of the inspection items. Traditionally, the removal of such defective products relies on manual labor or height-limiting devices. However, manual screening is inefficient; conventional height-limiting devices use hard contact, which, while effectively intercepting defective products, may cause cosmetic damage.

[0003] In the prior art, patent CN115106301A discloses an automatic capacitor feeding height limit rejection device, including: a feeding tray and capacitor bodies; a gripping mechanism is provided on one side of the flat conveying track, the gripping mechanism including an up-and-down rotating cylinder, a rotating shaft, a fixed horizontal plate, a clamping component, an adjusting component, a height limit block, and a detector; a blocking component is provided on the side of the flat conveying track. When an excessively tall capacitor body passes by, it will be blocked by the height limit block. At this time, the capacitor body blocking is determined to be an excessively tall capacitor body. At this point, the feeding tray stops feeding, and the clamping component of the gripping mechanism closes to clamp the excessively tall capacitor body. Although it can solve the problem of defective capacitors that are taller than qualified capacitors in the prior art, it uses a hard contact method with the height limit block and uses a complex gripping mechanism to remove defective capacitors from the flat conveying track, which is costly.

The transition track has a first through slot and a second through slot of the same specifications as the through slots, which are parallel to each other. The height detection component is installed on one side of the first vibrating track. The transition track is located between the first and second vibrating tracks, and the first through slot of the transition track connects to the through slots on both sides. When a capacitor detected as defective by the height detection component moves into the first through slot, the linear mechanism drives the second through slot to translate until it aligns with the through slot, and the rejection device rejects the defective capacitors that have moved out of the capacitor conveying queue.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] refer to Figures 1-6An automatic rejection device for capacitors with limited feeding height includes a conveying track for conveying capacitors via linear vibration, a height detection component, and a rejection device for rejecting defective capacitors based on the detection result of the height detection component. The conveying track includes a first vibrating track 1 and a second vibrating track 3. The rejection device includes a transition track 2, a linear mechanism for driving the transition track 2 to translate, and a rejection device for removing capacitors from the transition track 2. The first vibrating track 1 and the second vibrating track 3 are respectively provided with through slots for capacitors to pass through. The transition track 2 has a first through slot 21 and a second through slot 22 of the same specifications as the through slots, which are parallel to each other. The height detection component is installed on one side of the first vibrating track 1. The transition track 2 is located between the first vibrating track 1 and the second vibrating track 3, and the first through slot 21 of the transition track 2 is connected to the through slots on both sides. When a capacitor detected as defective by the height detection component moves into the first through slot 21, the linear mechanism drives the second through slot 22 to translate until it is aligned with the through slot, and the rejection device rejects the defective capacitors that have moved out of the capacitor conveying queue from the first through slot 21. When a capacitor detected as defective by the height detection component moves into the second channel 22, the linear mechanism then drives the first channel 21 (where defective products have already been removed) to move horizontally until it aligns with the through channel. The rejection device then removes the defective products that have been moved out of the capacitor transport queue and are now in the second channel 22. This invention employs a segmented transport track combined with a transition track 2, allowing defective products to be moved out of the capacitor transport queue without interrupting normal capacitor transport. This enables selective rejection of defective products, improving the continuity and stability of the system operation. The automatic operation of this invention can be achieved using conventional control technology. Typically, a control system is required, and operators need to pre-configure and set the operating time intervals for the linear mechanism, rejection device, and the detected defective capacitors.

[0031] Preferred, Reference Figures 1-3 The linear mechanism includes a slide rail 5 and a cylinder 53 mounted on the working surface; both ends of the slide rail 5 are mounted on the working surface via rail seats 51; a slide seat 52 is fixed at the bottom of the transition track 2, and the slide seat 52 is slidably connected to the slide rail 5; a connecting block 23 is fixed at the bottom of the transition track 2, and the connecting block 23 is connected to the piston rod of the cylinder 53; the cylinder 53 moves rapidly and can quickly switch between the first through groove 21 and the second through groove 22.

[0032] In one embodiment, reference Figure 1The rejection device includes an air pump and an air pipe 65 connected to the air outlet of the air pump. The end of the air pipe 65 furthest from the air pump is fixed to the end of the first vibrating track 1 or the second vibrating track 3 near the transition track 2. The outlet of the air pipe 65 points to the position of the defective product that has been removed from the capacitor conveying queue by the transition track 2. When a defective product enters the rejection area, airflow is ejected through the air pipe 65 to blow it away from the conveying track. This airflow-driven method avoids physical impact on the capacitors and is compact, low-cost, and easy to maintain. The air pump can be turned on only when rejection is needed to provide airflow to push the capacitors, or it can be continuously supplied with air.

[0033] In an optional embodiment, the rejection device includes a push-pull electromagnet, which is horizontally arranged, and the actuating end of the push-pull electromagnet is fixed with a push block whose size is smaller than the width of the through slot. When the defective product is misaligned out of the capacitor's conveying queue, the electromagnet is energized to push the push block, pushing the defective product laterally out of the first through slot 21 or the second through slot 22.

[0034] In an optional embodiment, refer to Figures 2-6 The rejection device includes an upper shaft 61 mounted above the transition track 2 and a motor 6 for driving the upper shaft 61 to rotate. The motor 6 is fixed by a first support 64 mounted on the working surface. Two fan blades are mounted on the upper shaft 61. The fan blades are non-rigid, and their width is less than the width of the through slot. The first fan blade 62 is responsible for rejecting defective products in the first through slot 21, and the second fan blade 63 is responsible for rejecting defective products in the second through slot 22. The rotation plane of the fan blades is parallel to the extension direction of the through slot, and the movement trajectory of the fan blades passes through the position of defective products removed from the capacitor conveying queue by the transition track 2. The minimum distance from the fan blade to the first through slot 21 or the second through slot 22 is less than half the height of the capacitor. The fan blades can be made of materials such as plastic sheets, rubber sheets, or brush bristles. When defective products enter the rejection area, motor 6 starts, driving the fan blades to rotate. The flexible fan blades gently deflect the defective products away from the conveyor path. This gentle and non-destructive rejection method allows motor 6 to drive the upper shaft 61 to rotate continuously or activate when the height detection component detects a defective product (equivalent to pre-activation), providing uniform fan blade rotation, stable operation, and high reliability. A well-designed distance between the fan blades and the guide slot ensures effective rejection while avoiding interference with the normal capacitors, thus improving the system's stability and reliability.

[0035] Considering the small size of the capacitor, refer to Figures 1-3 The lengths of the first through slot 21 and the second through slot 22 are the sum of the diameters of 1 to 3 capacitors, to ensure that the transition track 2 has a certain length to facilitate assembly and reduce the difficulty of locating defective products. This length range takes into account both rejection efficiency and equipment space layout requirements.

[0036] Preferably, the bottom surfaces of the first through groove 21 and the second through groove 22 are inclined, with the end near the first vibration track 1 lower than the bottom surface of the through groove, and the end near the second vibration track 3 higher than the bottom surface of the through groove; the height difference between the inclined ends of the bottom surfaces of the first through groove 21 and the second through groove 22 and the bottom surface of the through groove is no greater than 2mm, for example, about 1mm. (Reference) Figures 4-5 The diagram schematically marks the bottom surface of the first channel 21 (denoted as the first channel bottom surface 201) and the bottom surface of the second channel 22 (the second channel bottom surface 202). This design facilitates the smooth entry and exit of capacitors from the channels, prevents capacitor transport from being stuck due to height differences between the tracks, reduces the risk of blockage, and improves the smoothness of capacitor transport.

[0037] The height detection component can employ the height-limiting structure and power-off structure connected by a support frame, as well as laser ranging technology, as described in existing technology patent CN215656482U. Preferably, refer to... Figure 6 The height detection component includes a first mounting plate 46 fixedly installed above the first vibration track 1, a detection wheel 4 mounted on the first mounting plate 46 via a first height adjustment component 41, a second mounting plate 47 fixed above the first mounting plate 46, and a switch 45 mounted on the second mounting plate 47 via a second height adjustment component 44; the first mounting plate 46 and the second mounting plate 47 are fixed on a second support 48 installed on one side of the first vibration track 1; the first height adjustment component 41 can move up and down relative to the first mounting plate 46, so that the detection wheel 4 can adapt to and contact the top surfaces of capacitors at different heights in the capacitor delivery queue; the outer periphery of the detection wheel 4 is provided with a flexible layer, which can be a rubber layer, a cloth sleeve, a plastic layer, a silicone layer, etc. A height limiting component is fixed to the upper part of the second height adjusting component 44, and the height limiting component contacts the top surface of the first mounting plate 46. The first height adjusting component 41 can be a stud, and the height limiting component is a height limiting nut 42 that engages with the stud thread. The second height limiting component can be a bolt with the bolt head facing downwards, and a switch 45 is glued to the head of the bolt. The switch 45 can be a push-button switch 45. A compression spring 43 is sleeved on the height limiting component between the detection wheel 4 and the first mounting plate 46. The compression spring 43 ensures that the detection wheel 4 is always in close contact with the capacitor surface, improving detection accuracy. This invention can adapt to changes in the top surface of capacitors of different heights and achieves height detection by the up-and-down floating of the detection wheel 4. When the capacitor is too high, the top of the first height adjusting component 41 contacts the switch 45 and sends a signal to the control system. The control system triggers the linear mechanism to act after a delay. The flexible detection wheel 4 of this invention, combined with the spring buffer structure, improves detection sensitivity and accuracy, effectively reduces the false judgment rate, and avoids mechanical damage such as scratches to the capacitor.

[0038] Preferably, the working surface is also provided with a recycling box for receiving defective products rejected by the rejection device, which facilitates the centralized collection of defective products, improves the cleanliness of the site, and enhances the degree of automation and safety.

[0039] The working process of this utility model is as follows: When the height detection component determines that a capacitor is defective, the control system records the mark time. When the defective product moves with the conveyor queue to the first slot of the transition track, the linear mechanism is activated, driving the transition track to translate along the slide rail, aligning the second slot with the through slots on both sides, thereby displacing the defective product from the original conveying path. This allows for switching the conveying path via the translation of the transition track, completing the rejection operation without stopping the entire production line. This utility model significantly improves production efficiency through reasonable structural design and the selection of rejection methods, while also being simple in structure and responsive.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] On the other hand, it should be noted that, unless otherwise explicitly specified and limited, the terms "located at," "installed," "connected," and "linked" should be interpreted broadly.
