Description

Technical Field

[0001] This invention relates to the field of capacitor sandblasting, specifically to a capacitor feeding sandblasting device and a feeding sandblasting method. Background Technology

[0002] Capacitors, as a fundamental electronic component, are widely used in various electronic devices. During the production process, capacitor surfaces often require sandblasting to remove the oxide layer, improve adhesion for subsequent processes, or enhance appearance quality. Traditional capacitor sandblasting operations are mostly performed manually or semi-automatically, resulting in low efficiency, inconsistent quality, and high labor intensity. Therefore, the industry has gradually developed automated capacitor sandblasting equipment.

[0003] For example, Chinese patent application number CN202220968849.8 discloses a capacitor chip blasting cleaning machine, the structure of which includes a frame, a feeding device, a rubber chain conveyor, a spray gun device, and a core-exit conveyor. This equipment uses the rubber chain conveyor to clamp and transport capacitor chips, and the spray gun device cleans the capacitor chips by sandblasting during the transport process, realizing automated operation of capacitor sandblasting and improving production efficiency. However, the feeding device of this equipment only provides capacitors once and lacks an automatic recycling structure for the material boxes. Empty material boxes need to be removed manually or with additional equipment, affecting the continuous automation level of the production line.

[0004] Therefore, it is necessary to provide a capacitor feeding and sandblasting device and a feeding and sandblasting method. Summary of the Invention

[0005] The present invention provides a capacitor feeding and sandblasting device and method, which effectively solves the problem of low efficiency of existing capacitor spraying devices.

[0006] The technical solution adopted in this invention is: a capacitor feeding and sandblasting device, including a feeding mechanism and a sandblasting mechanism docked with the feeding mechanism. The feeding mechanism is used to provide capacitors to be sandblasted, and the sandblasting mechanism is used to sandblast the received capacitors.

[0007] Furthermore, the feeding mechanism includes a first frame, a material box, a lower belt conveyor line arranged along the Y-axis on the first frame for conveying the material box, an upper belt conveyor line arranged on the first frame for recycling the material box, a lifting assembly arranged on the first frame for receiving the material box on the lower belt conveyor line, a pushing assembly arranged on the first frame for pushing the capacitor placed in the material box in the lifting assembly, a feeding assembly arranged on the first frame, and a pushing assembly arranged on the first frame for pushing the material box to the upper belt conveyor line.

[0008] Furthermore, the material box includes a base plate, side plates disposed on the left and right sides of the base plate, and a top plate connecting the two side plates. Several material support grooves arranged along the height direction are provided on the opposite side of the two side plates for supporting the capacitors.

[0009] Furthermore, the upper belt conveyor line and the lower belt conveyor line have the same structure. The lower belt conveyor line includes a first driving pulley set on the first frame, several first driven pulleys, a first belt that is connected to the first driving pulley and the first driven pulley, and a first motor set on the first frame to drive the first driving pulley to rotate.

[0010] Furthermore, the lifting assembly includes a first support mounted on the first frame, a first linear guide rail vertically mounted on the first support, a first lifting seat slidably mounted on the first linear guide rail, a first linear module mounted on the first support for driving the first lifting seat to move up and down along the first linear guide rail, a support seat mounted on the first lifting seat, a clamping cylinder vertically mounted on the first lifting seat, and a first pressure plate mounted at the output end of the clamping cylinder.

[0011] Furthermore, the feeding assembly includes a second support mounted on the first frame, a conveying track mounted on the second support, a second drive wheel and several second driven wheels mounted on the second support, a second belt mounted on the second drive wheel and the second driven wheels, a second motor mounted on the second support for driving the second drive wheel to rotate, and elastic pressing components mounted on the second support and located at both ends of the second track.

[0012] Furthermore, the elastic pressing assembly includes a No. 3 cylinder vertically mounted on the No. 2 support, a mounting frame vertically mounted on the output end of the No. 3 cylinder, a lifting frame vertically slidably mounted on the mounting frame, elastic elements with both ends abutting against the upper end of the lifting frame and the mounting frame respectively, and a No. 3 wheel rotatably mounted on the lifting frame, the No. 3 wheel being able to extend into the conveying track.

[0013] Furthermore, the pusher assembly includes a No. 6 cylinder arranged on the No. 1 frame along the X-axis and a No. 6 plate arranged at the output end of the No. 6 cylinder.

[0014] Furthermore, the sandblasting mechanism includes a housing with an inlet and an outlet, a clamping conveyor line installed inside the housing, a sandblasting head installed inside the housing, and a power assembly located outside the housing for providing power to the sandblasting head. The clamping conveyor line includes two symmetrically arranged No. 4 and No. 5 belt lines inside the housing. The No. 4 belt line includes a No. 4 driving wheel and a No. 4 driven wheel installed inside the housing with the Z-axis as the rotation axis, a No. 4 belt that is connected to the No. 4 driving wheel and the No. 4 driven wheel, and a No. 4 motor installed inside the housing for driving the No. 4 driving wheel to rotate. The outer side of the No. 4 belt is provided with a support groove for supporting the side of the product.

[0015] The capacitor feeding and sandblasting method uses the aforementioned capacitor feeding and sandblasting device. The capacitor is fed to the sandblasting mechanism by the feeding mechanism, and then the capacitor is sandblasted by the sandblasting mechanism.

[0016] Beneficial effects of the invention: 1. This application constructs a complete automatic feeding and recycling system for material boxes by setting up a lower belt conveyor and an upper belt conveyor, in conjunction with a lifting assembly, a pushing assembly, and a box pushing assembly. The lower belt conveyor transports the fully loaded capacitor-laden material boxes to the lifting assembly, which lifts the boxes to the pushing station. After the pushing assembly has pushed all the capacitors to the feeding assembly, the box pushing assembly automatically pushes the empty boxes to the upper belt conveyor for recycling. This structure achieves full automation of the material box process from supply and positioning to recycling, completing the recycling of material boxes without manual intervention. This effectively reduces production line downtime and significantly improves the continuity and production efficiency of capacitor sandblasting operations.

[0017] 2. This application incorporates an elastic pressing component in the feeding assembly. This component, through an elastic element, drives the third wheel to maintain constant elastic contact with the capacitor surface, applying a stable clamping force to the capacitor and ensuring that it does not shift or jump during transport. Simultaneously, the clamping conveyor in the spraying mechanism employs two symmetrically arranged belt conveyors, with material support grooves on the outer sides of the belts matching the capacitor's shape, ensuring precise clamping and positioning of the capacitor during sandblasting. This dual guiding and positioning structure of elastic pressing and clamping material support effectively prevents positional shift of the capacitor during transport and sandblasting, ensuring uniform coverage of the capacitor surface by the sandblasting head, thereby significantly improving the consistency of the sandblasting process and product quality.

[0018] 3. The No. 3 wheel in the elastic pressing assembly can adapt to the height change of the capacitor under the action of the elastic element. It can adapt to the production needs of various specifications of capacitors without frequent replacement of parts, effectively reducing equipment modification costs and production changeover time, and meeting the flexible production needs of multiple varieties and small batches.

[0019] 4. This application integrates functional modules such as automatic feeding, material box circulation, capacitor conveying, sandblasting, and empty box recycling. The modules are linked in sequence through mechanical structures, forming a complete automated operation system. Operators only need to periodically replenish the material boxes and recycle empty ones, without directly participating in the handling, positioning, and sandblasting of capacitors, significantly reducing the frequency of manual intervention and labor intensity.

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1As shown, the first embodiment provided in this application is a capacitor feeding and sandblasting device, including a feeding mechanism 1 and a sandblasting mechanism 2 docked with the feeding mechanism 1. The feeding mechanism 1 is used to provide a capacitor to be sandblasted, and the sandblasting mechanism 2 is used to sandblast the received capacitor.

[0031] In actual use, the feeding mechanism 1 and the sandblasting mechanism 2 are connected to each other. The feeding mechanism 1 is used to transport the capacitors to be sandblasted to the sandblasting mechanism 2, and the sandblasting mechanism 2 performs sandblasting on the received capacitors, realizing the automated operation of capacitor surface treatment.

[0032] In the above design, the device of this application realizes the integration of automatic capacitor feeding and sandblasting, reduces manual operation links, and improves production efficiency and the stability and consistency of sandblasting process.

[0033] Specifically: such as Figure 2 As shown, the feeding mechanism 1 includes a first frame 11, a material box 12, a lower belt conveyor 13 arranged along the Y-axis on the first frame 11 for conveying the material box 12, an upper belt conveyor 14 arranged on the first frame 11 for recycling the material box 12, a lifting assembly 15 arranged on the first frame for receiving the material box 12 on the lower belt conveyor 13, a pushing assembly 16 arranged on the first frame 11 for pushing the capacitor placed in the material box 12 in the lifting assembly 15, a feeding assembly 17 arranged on the first frame 11, and a pushing assembly 18 arranged on the first frame 11 for pushing the material box 12 to the upper belt conveyor 14.

[0034] In actual use, the lower belt conveyor 13 transports the full material box 12 to the lifting component 15, the lifting component 15 lifts the material box 12 to the pushing position, the pushing component 16 pushes the capacitor to the feeding component 17, and the feeding component 17 feeds the capacitor into the sandblasting mechanism 2; the empty material box 12 is pushed by the box pushing component 18 to the upper belt conveyor 14 for recycling.

[0035] In the above design, the structural design and specific implementation of the feeding mechanism 1 realize the automatic feeding of capacitors and the automatic recycling of empty material box 12, forming a complete material box 12 cycle process, which improves the automation level and operating efficiency of the production line.

[0036] Specifically: such as Figure 3 As shown, the material box 12 includes a base plate 121, side plates 122 disposed on the left and right sides of the base plate 121, and a top plate connecting the two side plates 122. The two side plates 122 are provided with a plurality of material support grooves 120 arranged along the height direction for supporting the capacitor on opposite sides.

[0037] In actual use, the capacitors are placed in layers in the material tray 120, and the capacitors in each layer of the material tray 120 are pushed to the feeding component 17 by the pushing component 16 in sequence.

[0038] In the above design, the structural design and specific implementation of the material tray 120 enable the capacitors to be arranged neatly, avoiding collisions between capacitors, improving storage density and material retrieval accuracy, and facilitating the stable operation of subsequent automated processes.

[0039] Specifically: such as Figure 5 and Figure 4 As shown, the upper belt conveyor line 14 and the lower belt conveyor line 13 have the same structure. The lower belt conveyor line 13 includes a first driving pulley 131 and a first driven pulley 132 mounted on a first frame 11, a first belt 133 that is connected to the first driving pulley 131 and the first driven pulley 132, a side baffle 134 mounted on the first belt 133, and a first motor 135 mounted on the first frame 11 for driving the first driving pulley 131 to rotate.

[0040] In actual use, the No. 1 motor 135 drives the No. 1 active pulley 131 to rotate, and with the cooperation of the No. 1 driven pulley 132, it drives the No. 1 belt 133 to run. During the conveying of the material box 12, the side baffle 134 limits the material box 12 to the side away from the lifting component 15, thereby realizing the conveying of the material box 12.

[0041] In the above design, the structural design and specific implementation of the upper belt conveyor 14 and the lower belt conveyor 13 can achieve stable and continuous conveying of the material box 12, and the side baffle 134 prevents the material box 12 from tilting away from the lifting component 15 during the conveying process, thus meeting the high-efficiency operation requirements of the automated production line.

[0042] Specifically: such as Figure 2 and Figure 3 As shown, the lifting assembly 15 includes a first support 151 mounted on a first frame 11, a first linear guide rail 152 vertically mounted on the first support 151, a first lifting seat 153 slidably mounted on the first linear guide rail 152, a first linear module 154 mounted on the first support 151 for driving the first lifting seat 153 to move up and down along the first linear guide rail 152, a support seat 155 mounted on the first lifting seat 153, a pressing cylinder 156 vertically mounted on the first lifting seat 153, and a first pressure plate 157 mounted at the output end of the pressing cylinder 156.

[0043] In actual use, the lifting assembly 15 first drives the first lifting seat 153 to descend along the first linear guide rail 152 via the first linear module 154 to the height where it connects with the lower belt conveyor 13. This allows the full material box 12 in the lower belt conveyor 13 to be transported to the support seat 155, where the support seat 155 receives the material box 12. Then, the clamping cylinder 156 drives the first pressure plate 157 to clamp the material box 12. Subsequently, the first linear module 154 raises the first lifting seat 153 sequentially, causing the support seat 155 and the material box 12 to move upward synchronously. This ensures that after the pushing assembly 16 pushes a capacitor, the first linear module 154 drives the first lifting seat 153 to rise by one unit height. This continues until the capacitor in the material box 12 is completely transferred. Then, the clamping cylinder 156 drives the first pressure plate 157 to move upward, stopping the clamping of the material box 12. The pusher assembly 18 then pushes the empty box 12 from the carrier 155 to the upper belt conveyor 14.

[0044] In the above design, the structural design and specific implementation of the lifting component 15 can accurately control the height position of the material box 12. In conjunction with the clamping structure, it avoids the material box 12 from shaking or shifting during operation, thereby improving the accuracy and safety of pushing and picking up materials.

[0045] Specifically: such as Figure 6 As shown, the feeding assembly 17 includes a second support 171 mounted on the first frame 11, a conveying track 172 mounted on the second support 171, a second drive wheel and several second driven wheels 174 mounted on the second support 171, a second belt connected to the second drive wheel and the second driven wheels 174, a second motor 173 mounted on the second support 171 for driving the second drive wheel, and elastic pressing assemblies 175 mounted on the second support 171 and located at both ends of the second track. Each end of the conveying track 172 corresponds to a second driven wheel 174.

[0046] In actual use, the capacitor in the material box 12 is pushed by the pushing component 16 onto the second belt of the feeding component 17. The second driving wheel is driven by the second motor 173 to rotate. With the cooperation of the second driven wheel 174, the second belt runs and the capacitor is conveyed on the conveying track 172. The elastic pressing components 175 located at both ends of the track limit and guide the capacitor to ensure that the capacitor is stably conveyed to the sandblasting mechanism 2.

[0047] In the above design, the structural design and specific implementation of the feeding component 17 facilitate smooth capacitor transmission, and the elastic pressing component 175 can adapt to the conveying requirements of capacitors of different specifications, thus improving the versatility and stability of the feeding.

[0048] Specifically: such as Figure 7As shown, the elastic pressing assembly 175 includes a third cylinder 1751 vertically mounted on the second support 171, a mounting frame 1752 vertically mounted on the output end of the third cylinder 1751, a lifting frame 1753 vertically slidably mounted on the mounting frame 1752, an elastic element 1754 whose two ends respectively abut against the upper end of the lifting frame 1753 and the mounting frame 1752, and a third wheel 1755 rotatably mounted on the lifting frame 1753, the third wheel 1755 being able to extend into the conveying track 172.

[0049] In actual use, before the capacitor passes the elastic pressure component, the elastic pressure component 175 drives the mounting frame 1752 to move down to a predetermined height via the third cylinder 1751. When the capacitor passes the elastic pressure component, it contacts the upper edge of the third wheel 1755, causing the third wheel 1755 and the lifting frame 1753 to press the elastic component 1754 upward to achieve floating. The capacitor moves until it contacts the third wheel 1755, causing the third wheel 1755 to roll, thereby causing the third wheel 1755 and the second belt to jointly roll and press the capacitor.

[0050] In the above design, the structural design and specific implementation of the elastic pressure component can adapt to the height change of the capacitor, avoid damage caused by rigid clamping, and ensure the stability of the capacitor's position during the conveying process, thereby improving the sandblasting accuracy and conveying reliability.

[0051] Specifically: such as Figure 2 As shown, the push box assembly 18 includes a sixth cylinder 181 disposed on the first frame 11 along the X-axis direction and a sixth plate 182 disposed at the output end of the sixth cylinder 181.

[0052] In actual use, after the capacitors in the material box 12 have been transferred, the material box 12 is at a height that can be directly pushed to the upper belt conveyor line 14 by the push box assembly 18. The sixth cylinder 181 drives the sixth plate 182 to push the empty material box 12 from the loading position to the upper belt conveyor line 14, thereby realizing the automatic recycling of the empty material box 12.

[0053] In the above design, the structural design and specific implementation of the push box component 18 realize the automatic discharge and recycling of empty material box 12, avoid manual intervention, and improve the automation level and overall operating efficiency of the material box 12.

[0054] Specifically: such as Figure 8As shown, the sandblasting mechanism 2 includes a housing with an inlet and an outlet, a clamping conveyor line 22 disposed within the housing, a sandblasting head 21 disposed within the housing, and a power assembly located outside the housing for providing power to the sandblasting head 21. The clamping conveyor line 22 includes two belt lines, No. 4 and No. 5, symmetrically disposed within the housing. The No. 4 belt line includes a No. 4 driving wheel and a No. 4 driven wheel disposed within the housing with the Z-axis as the rotation axis, a No. 4 belt that is connected to the No. 4 driving wheel and the No. 4 driven wheel, and a No. 4 motor disposed within the housing for driving the No. 4 driving wheel to rotate. The outer side of the No. 4 belt is provided with a support groove for supporting the side of the product.

[0055] In actual use, when the capacitor in the material box 12 is emptied, the sixth cylinder 181 drives the sixth plate 182 to push the empty material box 12 from the feeding position to the upper belt conveyor line 14, thereby realizing the automatic recycling of the empty material box 12.

[0056] In the above design, the push box assembly 18 realizes the automatic discharge and recycling of empty material boxes 12, avoiding manual intervention and improving the automation level and overall operating efficiency of the material box 12.

[0057] The second embodiment provided in this application is a capacitor feeding and sandblasting method. The capacitor feeding and sandblasting device described above is used. The capacitor is transported to the sandblasting mechanism 2 through the feeding mechanism 1, and then the capacitor is sandblasted by the sandblasting mechanism 2.

[0058] In the above design, the capacitor loading and sandblasting method can effectively achieve the loading and sandblasting of capacitors, thereby improving work efficiency.

[0059] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
