Description

Technical Field

[0001] The present invention relates to the field of feeding devices, in particular to automatic feeding equipment for processing electronic components. Background Art

[0002] A diode is a device with two electrodes that allows current to flow in only one direction.

[0003] After diode production, they need to be inspected. Existing methods involve placing the diodes on a rack and automatically inspecting them using industrial cameras. Once inspected, the diodes are removed from the rack and transported via a conveyor belt to a packaging station. Removing the diodes from the rack can be done manually or by an industrial robot using suction cups.

[0004] Manually removing diodes from the racks is inefficient and labor-intensive. Using an industrial robot with a suction cup to transfer diodes from the racks to a conveyor belt improves efficiency and reduces labor intensity. However, industrial robots are expensive to manufacture and maintain, requiring skilled maintenance personnel. Therefore, using an industrial robot with a suction cup to transfer diodes from the racks to the conveyor belt increases production costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic feeding device for processing electronic components, which can reduce production costs while improving diode production efficiency, facilitate maintenance and repair of equipment, and reduce the labor intensity of workers.

[0006] In order to achieve the above object, the technical solution provided by the present invention is:

[0007] The lifting mechanism that this sliding panel also is provided with is to be screwed on the lifting mechanism, and this sliding panel also is to be screwed on the lifting mechanism, and this sliding panel also is to be screwed on the lifting mechanism.

[0008] Specifically, the connection unit includes a connection plate, two adjacent connection plates are hingedly connected by a damping hinge, a groove is provided at the upper end of the connection plate, and the sliding plate is connected to the connection plate on one side thereof by a damping hinge.

[0009] Specifically, the material holding rack includes a rectangular frame, a material holding plate is fixed inside the frame, a plurality of placement slots are opened on the material holding plate, the electronic components to be processed are placed in the placement slots, and a protrusion is fixed at the lower end of the frame, which is inserted into the groove on the connecting plate.

[0010] Specifically, the lower end of the frame is in sliding contact with the bottom plate of the storage box.

[0011] Specifically, a sponge layer is fixed in the placement groove.

[0012] Specifically, the driving device includes a slide groove opened on the vertical side wall of the slide, and a forward and reverse screw is rotatably connected in any slide groove. A motor is fixed in the storage box, and the output shaft of the motor is fixedly connected to the forward and reverse screws. Sliders are fixed at the ends of the sliding plates, and the sliders are slidably engaged in the slide groove on one side thereof, and the sliders are threadedly connected to the forward and reverse screws.

[0013] Specifically, the upper end of the material storage box is hingedly connected to a cover plate, the cover plate is in sliding contact with the upper end of the material holding rack, and the cover plate and the material storage box are connected by a lock.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. After testing, the diodes on the rack can be temporarily stored in a storage box. When storing the diodes on the rack, the rack is placed vertically and inside the storage box, which can increase the storage capacity of the rack. The storage box can effectively protect the diodes on the rack, preventing the rack from being placed haphazardly and occupying the production space of the diode.

[0016] 2. After the motor is started, the two sliding plates can push the hinged plate chains on both sides to move toward the outside of the storage box. When the connecting unit of the hinged plate chain is separated from the slide and enters the outlet slot, the lower end of the material rack is separated from the bottom plate of the storage box. Under the action of the gravity of the material rack, the material rack and the connecting unit will rotate toward the outside of the storage box. During the rotation of the material rack toward the outside of the storage box, the diode on the material rack will automatically fall onto the conveyor belt and be transported, so that the diode on the material rack moves to the conveyor belt.

[0017] 3. As the material rack continuously rotates toward the outside of the storage box, when the material rack contacts the upper end of the conveyor belt, the material rack will be separated from the connecting unit under the action of the friction between the conveyor belt and the material rack and transported by the conveyor belt, which facilitates the separation of the material rack and the storage box.

[0018] 4. This automatic loading device has high working efficiency and reduces the labor intensity of workers. The equipment investment cost is low, and the maintenance and repair costs are low. The technical quality requirements of maintenance and repair personnel are not high, which can reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1 、 Figure 2 and Figure 8 As shown, an automatic loading device for processing electronic components includes a U-shaped storage box 1. Conveyor belts 14 are provided on both the left and right sides of the storage box 1. A slide 3 is provided on the bottom plate of the storage box 1, and outlet grooves 15 connected to the slide 3 are provided on both the left and right ends of the bottom plate of the storage box 1. Both sides of the slide 3 are slidably connected with hinged chain plates, which are hingedly formed by multiple connecting units, and the connecting units are detachably connected to the material rack. The upper end of the storage box 1 is hingedly connected to a cover plate 2, which is in sliding contact with the upper end of the material rack, and the cover plate 2 is connected to the storage box 1 by a lock.

[0031] After the diodes have been tested, they can be temporarily stored in the storage box 1. During this process, the diodes on the storage rack are held in a vertical position within the storage box 1, increasing the storage capacity of the rack. The storage box 1 effectively protects the diodes on the rack, preventing the rack from being randomly placed and occupying the production space for diodes.

[0032] The electronic components to be processed are located on the material rack, and the opposite ends of the two hinged chain plates are hingedly connected to a sliding plate 4, which is connected to a driving device in the storage box 1. The driving device allows the hinged chain plate to be driven by the sliding plate 4 to move toward the outlet slot 15 on one side.

[0033] like Figure 7 As shown, after the connecting unit is separated from the slide 3 and enters the outlet slot 15, the connecting unit in the outlet slot 15 and the material rack on the connecting unit in the outlet slot 15 are allowed to slowly rotate toward the outside of the storage box 1, and finally the electronic components to be processed on the material rack fall onto the conveyor belt 14. After the motor is started, the two sliding plates 4 can respectively push the hinged plate chains on both sides away from each other. When the connecting unit of the hinged plate chain is separated from the slide 3 and enters the outlet slot 15, the lower end of the material rack is separated from the bottom plate of the storage box 1. Under the action of the gravity of the material rack, the material rack and the connecting unit will rotate toward the outside of the storage box 1. During the process of the material rack rotating toward the outside of the storage box 1, the diodes on the material rack will automatically fall onto the conveyor belt 14 and be transported, thereby making it convenient for the diodes on the material rack to be moved to the conveyor belt 14.

[0034] like Figure 3 and Figure 4 As shown, the connection unit includes a connection plate 5, two adjacent connection plates 5 are hingedly connected by a damping hinge, a groove 6 is opened at the upper end of the connection plate 5, and the sliding plate 4 is connected to the connection plate 5 on one side by a damping hinge.

[0035] like Figure 5 and Figure 6As shown, the material holding rack includes a rectangular frame 11. The lower end of the frame 11 slides in contact with the bottom plate of the storage box 1, and the cover plate 2 slides in contact with the upper end of the material holding rack. Therefore, the sliding plate 4 pushes the connecting plate 5 and the material holding rack to prevent the material holding rack from tilting during movement within the storage box 1. A material holding plate 10 is fixed within the frame 11. The material holding plate 10 is provided with multiple placement slots 13, and a sponge layer is fixed within each placement slot 13. Through holes are provided on the material holding plate 10 at positions corresponding to the placement slots 13 to prevent the diodes from being adsorbed into the placement slots 13. After the diodes are placed in the placement slots 13, the sponge layer in the placement slots 13 can squeeze the diodes, thereby increasing the stability of the diodes within the placement slots 13. When the material holding rack is in a vertical position within the storage box 1, it can prevent the diodes from falling out of the placement slots 13. A protrusion 12 is fixed to the lower end of the frame 11, which is inserted into the groove 6 on the connecting plate 5.

[0036] As the material rack continuously rotates toward the outside of the storage box 1, when the material rack contacts the upper end of the conveyor belt 14, the material rack will be separated from the connecting unit and transported by the conveyor belt 14 under the action of the friction between the conveyor belt 14 and the material rack, facilitating the separation of the material rack and the storage box 1.

[0037] like Figure 2 As shown, the drive device includes a chute 8 provided on the vertical sidewall of the slideway 3. A forward and reverse screw 9 is rotatably connected within each chute 8. A motor is fixed within the storage box 1, and the motor's output shaft is fixedly connected to the forward and reverse screw 9. A slider 7 is fixed to each end of the sliding plate 4. The slider 7 slides and engages within the chute 8 on one side. The slider 7 is threadedly connected to the forward and reverse screw 9. The forward and reverse screw 9 includes two threaded segments, one corresponding to the hinged link plate on either side of the slideway 3. The two threaded segments can be used with the same or opposite thread directions.

[0038] This automatic loading device has high working efficiency and reduces the labor intensity of workers. The equipment investment cost is low, and the maintenance and repair costs are low. The technical quality requirements of maintenance and repair personnel are not high, which can reduce production costs.

[0039] The following is a detailed introduction to the use of the automatic feeding equipment for electronic component processing. The two threaded sections of the forward and reverse lead screws 9 have opposite thread directions.

[0040] After the diode detection on the material holding plate 10 is completed, the cover 2 is opened so that the material holding rack is in a vertical state and the protrusion 12 is located at the bottom. Then the material holding rack is installed into the storage box 1 and the protrusion 12 is inserted into the groove 6 of the connecting plate 5. Multiple material holding racks can be temporarily stored in the storage box 1.

[0041] When the diodes on the material receiving plate 10 need to be transferred to the conveyor belt 14, the conveyor belt 14 is started, causing the upper end of the conveyor belt 14 to move away from the material storage box 1. The motor is then started, causing the motor to rotate the forward and reverse screws 9. During the rotation of the forward and reverse screws 9, the two sliding plates 4 in the slideway 3 move away from each other, and the sliding plates 4 move toward the conveyor belt 14 on their side. As the sliding plates 4 move toward the conveyor belt 14 on their side, the multiple connecting plates 5 on one side of the sliding plates 4 move accordingly. When the connecting plates 5 separate from the slideway 3 and enter the outlet slot 15, the lower end of the frame 11 separates from the bottom plate of the material storage box 1, and the upper end of the frame 11 separates from the cover plate 2. Subsequently, under the action of gravity on the material receiving frame, the connecting plate 5 located in the outlet slot 15 and the material receiving frame thereon will rotate toward the outside of the material storage box 1. Under the torque buffering action of the damping hinge, the connecting plate 5 located in the outlet slot 15 and the material receiving frame thereon will slowly rotate toward the outside of the material storage box 1. During the rotation of the material receiving frame toward the outside of the material storage box 1, the diodes on the material receiving plate 10 will automatically fall onto the conveyor belt 14 and be transported to the packaging station. This facilitates the movement of the diodes on the material receiving frame onto the conveyor belt 14. The damping hinge has a buffering property. The connecting plate 5 located in the outlet slot 15 and the material receiving frame thereon will rotate toward the outside of the material storage box 1 due to the action of gravity. Due to the buffering action of the damping hinge, the connecting plate 5 located in the outlet slot 15 and the material receiving frame thereon will slowly rotate toward the outside of the material storage box 1. The damping hinge is prior art and will not be described in detail here.

[0042] As the material rack rotates toward the outside of the storage box 1, when the material rack contacts the upper end of the conveyor belt 14, the friction between the conveyor belt 14 and the material rack causes the material rack to separate from the connecting unit and be transported by the conveyor belt 14, thus facilitating the separation of the material rack from the storage box 1. The forward and reverse rotation of the lead screw 9 can be controlled by the motor to intermittently rotate, thereby allowing the multiple material racks in the storage box 1 to be intermittently rotated out of the storage box 1. In addition, the forward and reverse rotation of the motor can be controlled to realize the collection of the connecting unit separated from the material rack into the storage box 1.

[0043] Because this application only details the technical contributions of the prior art and does not describe actual product applications, some omissions are inevitable. For example, baffles should be installed on both sides of the conveyor belt 14 to prevent diodes that have detached from the material rack from falling to the ground on both sides of the conveyor belt 14; the thickness of the sponge layer should be appropriately designed to prevent diodes from becoming stuck in the placement slot 13.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
