Abstract

This application discloses a sandblasting device for removing residual adhesive from capacitor leads. A reciprocating mechanism drives the spray gun module to perform cyclic reciprocating horizontal movement along the width of the conveyor belt, covering the working area of ​​all connected capacitors on the sandblasting feed tray. This allows for dynamic adjustment and accurate alignment of the sandblasting position, improving the residual adhesive removal effect.

Description

Technical Field

[0001] This application relates to the field of capacitor processing technology, and more specifically to a sandblasting device for removing residual adhesive from capacitor leads. Background Technology

[0002] Currently, the commonly used sandblasting machines on the market are mainly used for cleaning the leads and side residues of integrated capacitors. Their typical structure includes a sandblasting machine body, a conveyor belt system, a roller clamping device, a sandblasting module, and related pneumatic and material supply systems.

[0003] In existing technologies, integrated capacitors are fed into the sandblasting area via a conveyor belt. A pair of rollers are installed above and below the conveyor belt to press and position the integrated capacitors. Once the integrated capacitors reach the spray gun module, the sandblasting module, propelled by compressed air, sprays a sand-water mixture onto the sides and leads of the integrated capacitors to remove residual adhesive generated during die-cutting or tinning. This process effectively removes residual adhesive, improving the reliability of subsequent assembly.

[0004] However, the above design still has several shortcomings:

[0005] 1. The fixed position of the spray gun module cannot adapt to the slight offset of the integrated capacitor on the conveyor belt, resulting in misalignment between the sandblasting area and the actual position of the integrated capacitor, thus reducing the quality of sandblasting to remove residual adhesive.

[0006] 2. When relying solely on rollers to press and position the integrated capacitor, the rollers only contact the lower and side surfaces of the integrated capacitor and cannot cover its upper and lower surfaces. This can easily lead to the formation of mottled or uneven pitted surfaces on the device surface during sandblasting, affecting the product's appearance and sealing performance.

[0007] 3. When the roller installation or tensioning device becomes loose, the integrated capacitor may fall from the roller clamping area to below the conveyor belt, causing production stoppage, equipment damage or product scrap, seriously affecting the stability of the production line.

[0008] 4. All integrated capacitors use a fixed conveyor belt width, which is not compatible with other sizes or models of integrated capacitors. The sandblasting machine can only operate on products of a single specification, which limits the versatility and flexibility of the equipment.

[0009] Therefore, in response to the above-mentioned technical deficiencies, there is an urgent need for a sandblasting device that can accurately align the position of integrated capacitors of different specifications, fully cover the workpiece surface to avoid damage, firmly fix the device, and be versatile for multiple specifications, so as to improve the efficiency of residual adhesive removal and product quality.

[0031] like Figures 1-5As shown, a sandblasting device for removing residual adhesive from capacitor leads includes a sandblasting machine body 1, a conveyor belt system 2, sandblasting discharge trays 3, a reciprocating moving mechanism 4, and a sandblasting module 5. The conveyor belt system 2 is located at a lower position inside the sandblasting machine body 1. The conveyor belt system 2 is a horizontal conveying mechanism, and its structure is a common combination of rollers and conveyor belts in the prior art, which will not be elaborated here. Multiple sandblasting discharge trays 3 are evenly arranged along the conveying direction on the horizontal conveying surface of the conveyor belt system 2. Multiple integrated capacitors 6 are evenly arranged inside the sandblasting discharge trays 3. The reciprocating moving mechanism 4 is fixedly installed on the top of the sandblasting machine body 1, and the sandblasting module 5 is fixedly installed on the reciprocating moving mechanism 4. On mechanism 4, the sandblasting module 5 is located in the middle section inside the sandblasting machine body 1 and faces the horizontal conveying surface of the conveyor belt system 2. The sandblasting module 5 is connected to the sandblasting material storage device and the compressed air device through two sets of hoses respectively. The reciprocating moving mechanism 4 can drive the sandblasting module 5 to move horizontally back and forth along the width direction of the horizontal conveying surface of the conveyor belt system 2, and the range of the moving path of the sandblasting module 5 is larger than the arrangement range of the sandblasting discharge tray 3 in the width direction of the horizontal conveying surface of the conveyor belt system 2. In this design, by driving the spray gun module to move horizontally back and forth in the width direction of the conveyor belt through the reciprocating moving mechanism 4, all the connected capacitors on the sandblasting discharge tray 3 can be covered. The working area of ​​the device 6 enables dynamic adjustment and accurate alignment of the sandblasting position, significantly improving the residual adhesive removal effect. At least two sets of baffles 7 are arranged along the width direction on the horizontal conveying surface of the conveyor belt system 2. Each set of baffles 7 consists of two baffles 7, with the length direction of the baffles 7 aligned with the conveying direction of the conveyor belt system 2. Each baffle 7 is fixedly connected to a crossbar 8, which is fixedly installed on the sandblasting machine body 1.

The bottom of the limiting rod 9 contacts the top of the baffle 7. The distance between any two adjacent limiting rods 9 is less than the length and width of the sandblasting discharge tray 3. In the design, the sandblasting discharge tray 3 is equipped with a strip-shaped placement groove and a baffle 7 and limiting rod 9 structure that cooperate with it. During the conveying and sandblasting process, the integrated capacitor 6 is firmly fixed in the groove to prevent loosening or falling, and to ensure the continuous and stable operation of the production line.

[0032] In one embodiment, combined Figure 6The sandblasting discharge tray 3 has multiple placement slots 31 evenly spaced along its length and width. The length and width dimensions of the placement slots 31 are adapted to the length and width dimensions of the integrated capacitor 6. A support strip 32 is fixedly installed at the bottom opening of each placement slot 31, and an installation strip 33 can be detachably installed at the top opening of each placement slot 31. Both ends of the installation strip 33 are fixedly provided with inserts 34, and both ends of the top opening of the placement slot 31 are provided with slots 35. The installation strip 33 is fixedly installed at the top opening of the placement slot 31 by the insertion of the inserts 34 and the slots 35. The length direction of the installation strip 33 and the support strip 32 is consistent with the length direction of the placement slot 31, and the width of the installation strip 33 and the support strip 32 is... The dimensions are smaller than the width of the placement slot 31. When the integrated capacitor 6 is placed in the placement slot 31, the pins of the integrated capacitor 6 can be exposed through the gap between the mounting strip 33 and the support strip 32 and the placement slot 31. In this design, the sandblasting feed tray 3 is equipped with a detachable mounting strip 33 and a fixed support strip 32, which cover the upper and lower surfaces of the integrated capacitor 6, exposing the pins and side areas that need to be sandblasted in the gap. This effectively avoids sandblasting from causing pitting on the surface of the device and ensures that the surface of the device is flat and smooth. By matching sandblasting feed trays 3 of different specifications, the same sandblasting machine can be quickly changed to adapt to integrated capacitors 6 of various sizes and models, greatly improving the versatility of the equipment and the flexibility of production, and reducing the cost of production line transformation.

That is, when the movable plate 44 contacts the limiter 46, the limiter 46 transmits a signal to the controller, which controls the drive motor 49 to run in the opposite direction, thereby causing the movable plate 44 to reciprocate along the slide rail 42. The horizontal part of the movable plate 44 is fixedly connected to the L-shaped connecting plate 45. A strip-shaped through hole 47 is provided on one side of the support frame 41 on the top of the sandblasting machine body 1.

The two connecting brackets 51 are symmetrically arranged. The other end of the two connecting brackets 51 extends to the middle section of the sandblasting machine body 1, and at least two sandblasting guns 52 are fixedly installed on both.

Each sandblasting gun 52 is connected to the sandblasting material storage device and the compressed air device through two sets of hoses respectively. Under the negative pressure of the compressed air, the sand-water mixture solution in the sandblasting material storage device is transported to the sandblasting gun 52 through the hose and sprayed out.
