Description

Technical Field

[0001] This utility model relates to the field of resistive element equipment technology, and in particular to an automatic electronic component loading device. Background Technology

[0002] A resistor is an electronic component that impedes the flow of electric current. Some types of resistors on the market are quite small, and they need to be inspected before being shipped to the manufacturer or manufactured to check for wear or damage. Only after passing inspection can they be used in the next stage of production.

[0003] The prior art, authorized by CN210392899U, discloses a material tray loading and unloading module. However, the current resistive elements need to be placed into the same material tray's boxes in a positive and negative manner. Multiple sets of boxes are set in one material tray and filled. The prior art has certain limitations and therefore cannot meet the above requirements.

[0004] Currently, in actual production, two sets of machines are used. One set is used to install the front-side trays. After the front-side resistors are installed, the trays are transferred to the equipment for installing the back-side resistors, and then the back-side resistors are placed to complete the assembly. Alternatively, the same set of equipment can be used to install the front-side components first, and then install the back-side components. However, the above methods are inefficient, as the second set cannot be completed until the first set is finished.

[0005] Therefore, it is necessary to design an automatic electronic component loading device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic electronic component loading device to overcome the aforementioned shortcomings of the existing technology.

The module includes mounting brackets on both sides of the conveying mechanism, a horizontal longitudinal electric servo module on the mounting brackets, and an automatic detection and picking module that is driven by the horizontal longitudinal electric servo module to move horizontally perpendicular to the conveying direction of the conveying mechanism.

[0009] Preferably, the automatic detection and pickup module includes a mounting base, a vision inspection camera mounted on the mounting base, and a resistive element pickup module mounted on the side of the vision inspection camera.

They include a material belt conveying unit for conveying the material tray, a double-side plate clamping unit arranged on both sides of the material belt conveying unit and capable of being driven to approach or separate, and a material tray top unit placed in the middle of the material belt conveying unit and capable of being driven up and down.

[0012] Preferably, the dual-side plate clamping unit includes clamping plates respectively disposed on both sides of the material conveying unit, and a driving unit that moves in a direction perpendicular to the conveying direction of the material conveying unit. A limit block is also provided on the inner side plate of the clamping plate.

[0017] Reference Figures 1 to 4 An automatic electronic component loading device includes a tray feeding mechanism 1, a tray receiving mechanism 2, a conveying mechanism 3 disposed between the tray feeding mechanism 1 and the tray receiving mechanism 2, a first feeding position and a second feeding position disposed sequentially along the conveying mechanism 3 between the tray feeding mechanism 1 and the tray receiving mechanism 2, a front-side picking module 4 disposed above the first feeding position, a reverse-side picking module 5 disposed above the second feeding position, a first feeding module 6 located on one side of the conveying mechanism 3 and supplying positive resistance elements, and a second feeding module 7 located on the other side of the conveying mechanism 3 and supplying reverse resistance elements.

[0018] The front material picking module 4 and the back material picking module 5 have the same structure and are arranged opposite each other on the conveying mechanism 3. They include mounting brackets 41 on both sides of the conveying mechanism 3, a horizontal longitudinal electric servo module 42 on the mounting brackets 41, and an automatic detection and picking module 43 driven by the horizontal longitudinal electric servo module 42 to move horizontally perpendicular to the conveying direction of the conveying mechanism 3.

[0019] The automatic detection and picking module 43 includes a mounting base 431, a vision inspection camera 432 mounted on the mounting base 431, and a resistor element picking module 433 mounted on the side of the vision inspection camera 432. The vision inspection camera 432 is used to position the resistor element to be picked up, and at the same time, it is also necessary to position the element to be placed, i.e., the hopper in the tray.

[0020] The resistor element picking module can be a cylinder gripper, a suction head with adsorption function, or any other mechanism capable of picking up and transporting the resistor atoms provided by the first feeding module 6 and the second feeding module 7; the structure of the unloading robot mechanism can be referred to in the existing patent, publication number CN210392899U.

[0021] The first feeding module 6 and the second feeding module 7 have the same structure and are assigned to cooperate with the front feeding module 4 and the back feeding module 5 for feeding. Each module includes a horizontal servo module 63 located on the side of the conveying mechanism 3, a feeding bin 62 driven by the horizontal servo module 63, a top-feeding unit 65 placed inside the feeding bin 62 for pushing electronic components up and down, and a material box 61 covering the top-feeding unit 65. The top-feeding unit 65 drives the resistive components inside the feeding bin 62 to be pushed out of the feeding bin 62 to cooperate with the front feeding module 4 or the back feeding module 5. Material handling is achieved by driving the feeding bin 62 to move horizontally via the horizontal servo module 63, adjusting the position of the feeding bin 62 to cooperate with the material handling by the front material handling module 4 and the back material handling module 5. For specific structure, please refer to the handling robot structure in the automatic assembly equipment and assembly method of motor rotor balance plate and stop ring in existing patent document publication number CN202311031817, or the content of the feeding device in existing patent document publication number CN2024200111412, or the content of the magazine feeding machine in existing patent document publication number CN2024209025978.

[0022] Both the front-side material picking module 4 and the back-side material picking module 5 are equipped with a detection camera 64 for detecting the resistive element to be picked up. The lens of the detection camera 64 is set upward and positioned below the front-side material picking module 4 or the back-side material picking module 5. The detection camera 64 detects the resistive element picked up by the automatic detection and picking module 43 to determine the position of the resistive element in the front-side material picking module 4 or the back-side material picking module 5, and at the same time detects whether the resistive element is in the direction that needs to be picked up.

[0023] The material tray feeding mechanism 1 and the material tray receiving mechanism 2 have the same structure and are respectively set at both ends of the conveying mechanism 3. One is used to feed an empty material tray and the other is used to receive a material tray full of resistive elements. It includes a material belt conveying unit 11 for conveying the material tray, a double side plate clamping unit 12 set on both sides of the material belt conveying unit 11 and capable of being driven to approach or separate, and a material tray top unit 13 placed in the middle of the material belt conveying unit 11 and capable of being driven up and down. The double-sided clamping unit 12 includes clamping plates respectively disposed on both sides of the conveyor belt unit 11, and a drive unit that moves in a direction perpendicular to the conveying direction of the conveyor belt unit 11. A limiting block 14 is also provided on the inner side plate of the clamping plate, the limiting block 14 being used to support the material tray. The drive unit drives the clamping plates closer together to clamp and fix the material tray; when they move away, the clamping is released. A gap remains between the stacked material trays for the limiting block 14 to insert. The specific loading and unloading process is as follows: Loading: Several empty material trays are first placed between the clamping plates and supported by the limiting blocks, while the clamping plates on both sides are in a clamping state. If an empty material tray needs to be loaded, the material tray top-loading unit... 13 moves upward until it hits the bottommost tray. After hitting the tray, the drive unit drives the clamping plate to separate, and the double-side plate clamping unit 12 cancels the clamping. Then the tray is supported by the tray top unit 13 and moves downward by one tray's position. The double-side plate clamping unit 12 drives the clamping, and the limiting block 14 is stuck between the bottom tray and the tray above it. Thus, the limiting block supports the other trays except the bottom two trays. The bottommost tray is supported by the tray top unit 13 and driven to move downward and be placed on the material belt conveyor unit 11. After the tray is placed on the material belt conveyor unit 11, it moves with the drive of the material belt conveyor unit 11 and is transferred to the conveying mechanism 3 to complete the loading. Unloading: The tray filled with resistive elements is moved by the conveying unit 11 to the conveyor belt 11 of the tray receiving mechanism 2. The conveyor belt 11 moves the tray to a designated area and stops. The tray top unit 13 drives upward, moving the full tray upward. After the top surface of the tray contacts the bottom surface of the clamped plate, the double-side plate clamping unit 12 releases. The tray top unit 13 then moves upward and back, clamping the tray. The double-side plate clamping unit 12 then clamps the tray, placing the limiting block on the bottom surface of the lowest tray for support, thus completing the loading process. Alternatively, the loading and unloading structure can be implemented using existing technologies described in the background section.

[0024] The conveying mechanism 3 includes a material belt conveying mechanism 31, a lifting, positioning and clamping mechanism 32 disposed in the middle of the material belt conveying mechanism 31 and used to support the material tray 33 and clamp the material tray. The material conveying mechanism 31 is a double material conveyor belt structure placed on both sides to facilitate the transmission of material trays, and a hollow space is left in the middle to facilitate the operation of the lifting, positioning and clamping mechanism 32. The lifting, positioning, and clamping mechanism 32 includes a base plate 321, clamping units 322 disposed on both sides of the base plate 321, a lifting plate 323 driven by the clamping units, a lifting cylinder 324 disposed on the lifting plate 323, and a lifting block 325 driven by the lifting cylinder to move up and down; the lifting block 325 is also provided with a clamping block 326, which, when moved to the area of ​​the lifting, positioning, and clamping mechanism 32, is driven by the lifting cylinder 324 to clamp. The clamping block 326 and the lifting block 325 move and contact the material tray. Since there is an empty slot on the material tray, the clamping block 326 passes through the material tray along the empty slot. The lifting plate 325 contacts the material tray, lifts the material tray, and takes it away from the material conveying mechanism 31. The clamping unit 322 drives the lifting block 325 and the clamping block 326 to move and clamp until the clamping blocks 326 around the perimeter contact the outside of the empty slot to achieve the purpose of clamping. At the same time, it is lifted away from the material conveying mechanism 31.

[0025] In this implementation, an empty material tray is first fed by the material tray feeding mechanism 1. The empty material tray moves along the conveyor mechanism 3 to the loading area until it stops at the lifting and positioning clamping mechanism 32. The lifting and positioning clamping mechanism 32 drives the corresponding empty material tray to be lifted away from the material conveying mechanism 31 of the conveyor mechanism 3, and clamped by the clamping block 326 to fix and limit the material tray. At this time, the front picking module 4 and the back picking module 5 begin to identify the position of the material slot on the material tray. After determining the position, they move to the positive resistance element loading module 6 and... The second feeding module 7 feeds materials. Each tray has 7 rows of material slots, and each row can hold 5 products. After the tray is lifted and positioned, the two picking modules complete the placement of materials for one row. After placement, the tray falls to the conveyor line and continues to be transported. After moving one row, it is lifted, positioned, and clamped again until it is full. After it is full, the lifting, positioning, and clamping mechanism 32 is reset, and the tray full of electronic components is placed back into the conveyor belt 31 to continue transporting. It is then moved to the tray receiving mechanism 2, where it is automatically unloaded.

[0026] The advantages of this utility model are that it sets up a conveying mechanism between the loading and unloading mechanisms on both sides, and sets up positive and negative picking modules on the conveying mechanism, as well as positive and negative motor component feeding modules that work with the positive and negative picking modules to feed materials. When the material tray moves to the area of ​​the conveying mechanism, the corresponding positive and negative resistor components are placed into the material tray through the identification and picking of the positive and negative picking modules, thereby realizing automatic loading. Compared with the prior art, this utility model completes the installation of the front and back components in one go, saving time and improving efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
