Description

Technical Field

[0001] The utility model belongs to the technical field of capacitor production equipment, and in particular relates to a capacitor element tray conveying mechanism. Background Art

[0002] Metallized film capacitors are capacitors made by winding or laminating double-sided metallized polypropylene films and non-metallized polypropylene films. The usual method of making film capacitors is to overlap metal foils such as aluminum as electrodes and plastic films and then wind them together. They have the advantages of small size, light weight, and stable frequency. Wound capacitors have become the mainstream type of film capacitors due to their simple structure and easy manufacturing.

[0003] At present, in the production process of capacitors, capacitors need to be transported on pallets, combined with manual coordination of production rhythm for efficient production. However, the conveying mechanism currently used to convey pallets is not on the same plane due to the need to set up workstations on the production line. For example, the transmission of pallets from one end of the production line to the other end of the production line can be completed by a conveying device, but the stacking and placement of pallets at both ends require manual coordination. After arriving at the designated workstation, the placement of capacitors on the pallet is completed manually, resulting in low overall production efficiency of the entire production line.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0043] like Figure 1-2 As shown, the utility model provides a capacitor element tray conveying mechanism, which includes: a conveying device, a loading lifting platform, a transplanting device, a unloading lifting platform and a unloading lifting platform.

[0044] The loading lifting platform is spaced apart from the first end of the conveying device, a plurality of trays are stacked on the loading lifting platform, and workstations for loading capacitor elements are arranged on both sides of the middle of the conveying device.

[0045] The transplanting device is arranged across the loading lifting platform and above the first end of the conveying device, and the transplanting device includes: a transplanting guide rod, a transplanting platform, a transplanting translation drive unit and a transplanting lifting drive cylinder. One end of the transplanting guide rod is arranged above the loading lifting platform, and the other end is arranged above the first end of the conveying device. The transplanting guide rod is arranged horizontally, spanning above the loading lifting platform and the first end of the conveying device. The transplanting platform is slidably connected to the transplanting guide rod, and the output end of the transplanting translation drive unit is connected to the transplanting platform for driving the transplanting platform to reciprocate on the transplanting guide rod. The transplanting lifting drive cylinder is arranged on the transplanting platform, and its output end passes through the transplanting platform and is connected with a suction cup assembly for adsorbing the tray, which is used to transfer the tray on the loading lifting platform to the conveying device.

[0046] The conveying device includes two parallel conveyor belts, and the two sides of the pallet are placed on the two conveyor belts for movement.

[0047] The unloading lifting platform is arranged at the top of the second end of the conveying device; the unloading lifting platform is arranged at the bottom of the second end of the conveying device, and is arranged opposite to the unloading lifting platform. The output end of the unloading lifting platform can pass through and rise between the two conveyor belts of the conveying device, and cooperate with the unloading lifting platform above to lift the pallet on the second end of the conveying device and move it to the unloading lifting platform.

[0048] By lifting the empty pallet on the loading lifting platform, the operator only needs to place a stack of empty pallets on the loading lifting platform, and then the transplanting lifting drive cylinder in the transplanting device drives the suction cup assembly to move downward to adsorb the pallet above the loading lifting platform, and the transplanting translation drive cylinder unit drives the empty pallet to move along the direction of the transplanting guide rod, and drives the empty pallet to the top of the first end of the conveying device. The transplanting lifting drive cylinder drives the empty pallet to descend and automatically completes the grabbing of the empty pallet. In response to the situation on the same plane, the transfer efficiency is high. At the same time, the unloading lifting platform at the second end of the conveying device can lift the loaded pallet to the unloading lifting platform for easy subsequent removal.

[0049] In this embodiment, a centering device is also included, which is symmetrically arranged on both sides of the conveying device and is used to clamp and position the passing pallet inward to facilitate subsequent straight delivery to the second end of the conveying device;

[0050] The centering device comprises a centering drive cylinder and a push plate.

[0051] The centering drive cylinder is arranged on the outer side of the conveying device along a direction perpendicular to the length of the conveying device; the push plate is arranged at the output end of the centering drive cylinder, and is used to push inward to limit the side edge of the pallet. When the centering operation is performed, the centering devices on both sides move inward at the same time.

[0052] A first sensor is provided in the conveying device between the centering devices for detecting the position of the pallet between the centering devices. The first sensor may be a sensor such as a micro switch, which is provided between the two conveyor belts. When the pallet passes by, it contacts the output end of the micro switch. At this time, it is judged that the pallet is between the two reconciliation devices, and then the centering device is controlled to perform a centering operation on the pallet.

[0053] The loading lifting platform has the same structure as the unloading lifting platform. The specific structure of the unloading lifting platform will not be repeated here. The unloading lifting platform can be understood by describing the structure of the loading lifting platform. The loading lifting platform includes: a first support plate, a second support plate, and a lifting screw rod;

[0054] The first support plate is fixed on the frame, and the second support plate is spaced apart from the first support plate. The second support plate is arranged at the bottom of the first support plate and is guided and connected by multiple guide rods. A lifting drive cylinder is arranged on the second support plate to provide a driving force for lifting and lowering. The lifting screw rod is connected to the second support plate through a screw rod bearing, and the screw rod bearing is fixed on the second support plate. One end of the lifting screw rod is transmission connected to the lifting drive cylinder. When the lifting drive cylinder drives the lifting screw rod to rotate, the lifting screw rod and the screw rod bearing rotate to drive the second support plate to move up. The other end of the lifting screw rod passes through the first support plate and is connected to a supporting plate, thereby driving the supporting plate to move up and down. The width of the supporting plate is smaller than the interval between the two conveyor belts to avoid interference with the conveyor belt when moving up and down.

[0055] A sensor bracket is vertically arranged on the first supporting plate, and a vertical waist-shaped hole is opened on the sensor bracket. A second sensor and a third sensor are arranged on the sensor bracket at intervals up and down. The two sensors are fixed in the waist-shaped hole, and are used to determine the upward height limit of the tray on the supporting plate, that is, to control the upper surface of the tray to be located between the second sensor and the third sensor, so as to facilitate the upper suction cup assembly to accurately control the downward movement stroke, and then accurately suck the uppermost tray.

[0056] In order to ensure the accuracy of the loading and unloading lifting platforms during lifting, a positioning sensing plate is arranged on the second support plate, and a positioning mark rod is arranged at the bottom of the first support plate, and the positioning mark rod extends toward the second support plate. An upper limit sensor, a lower limit sensor and a zero point sensor located between the upper limit sensor and the lower limit sensor corresponding to the positioning sensing plate are slidably fixed on the positioning mark rod. When the positioning sensing plate passes through the zero point sensor, it is determined that the lifting drive cylinder is in the initial position at this time, which is convenient for controlling the lifting stroke of the support plate each time thereafter, and is convenient for cooperating with the upper unloading lifting platform to move the pallet on the conveyor belt up and place it on the unloading lifting platform.

[0057] Specifically, the unloading lifting platform includes: a lifting frame and a lifting cylinder.

[0058] The lifting frames are arranged on both sides of the second end of the conveying device, the lifting cylinder is fixed on the lifting frames, the extension direction of the lifting cylinder is toward the conveying device, and the output end of the lifting cylinder is provided with a lifting plate, which is used to support the pallet lifted during the rising process of the unloading lifting platform. Full pallets are placed on the two lifting plates. When the supporting plates move up, the full pallet on the second end of the conveyor belt is lifted and moved to the full pallet at the bottom of the lifting plates, and then the lifting plates on both sides move outward, and then the supporting plates continue to move up a certain distance, and then the lifting plates on both sides move inward, and then the supporting plates move down again, and the entire stack of full pallets is placed on the lifting plates on both sides, completing the moving of the full pallets on the conveyor belt to the lifting platform.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
