Description

Technical Field

[0001] This utility model relates to the field of surface mount technology, specifically to an intelligent SMT (Surface Mount Technology) error-proof material handling and feeding device. Background Technology

[0002] SMT (Surface Mount Technology) refers to a series of processes performed on a PCB (Printed Circuit Board). The feed station's trays deliver tape to the pick-and-place machine, enabling it to complete the placement. Typically, when the tape in the old tray at the feed station is about to run out, the operator needs to remove the old tray, retrieve a new tray, and connect the beginning of the new tray's tape to the end of the old tray's tape using a receiving machine. The new tray is then placed back at the feed station to continue feeding the old tray.

[0003] To avoid incorrect placement of material trays, scanning and inspection instruments are generally used to scan the station codes on the machine and the material labels on the trays. During scanning, the operator usually needs to hold the inspection instrument by hand, which is a lot of work. At the same time, because the spacing between the station codes is small, the operator is very likely to make mistakes when scanning, so rework inspection is required. In addition, when using manual scanning and inspection, it is very easy to miss scans.

[0004] To address this, an intelligent SMT (Surface Mount Technology) error-proof material handling and feeding device is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides an intelligent SMT error-proof material handling and feeding device.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] The SMT intelligent error-proof material handling and loading device includes a tray placement rack and a frame. Multiple indicator lights are located on one side of the frame, and a first electric telescopic rod is located below each indicator light. The telescopic end of the first electric telescopic rod is connected to a fixing plate. A pick-and-place machine station code is located on one side of the fixing plate. Multiple evenly arranged partitions are provided on the tray placement rack, forming placement cavities for the tray body. The placement cavities correspond one-to-one with the positions of the indicator lights. Position adjustment components for adjusting the position of the tray body and detection components for scanning and detecting material labels on the tray body are respectively provided on adjacent sides of the tray placement rack. The position adjustment component includes a second driving component for moving the clamping component, and the detection component includes a driving component for moving the scanning and detection device.

[0008] Furthermore, the driving component includes a second slide rail, a first motor, a first slider, a lead screw, a connecting plate, and a third electric telescopic rod.

[0009] Furthermore, the first motor is disposed on one side of the second slide rail, the first slider is slidably disposed inside the second slide rail, the lead screw is connected to the main shaft end of the first motor, the first slider is threaded onto the lead screw, the connecting plate is disposed at the top of the first slider, the third electric telescopic rod is disposed on one side of the connecting plate, and the scanning detection device is connected to the telescopic end of the third electric telescopic rod.

[0010] Furthermore, the second driving component includes a first slide rail and a vertical plate slidably disposed above the first slide rail. An inclined plate is provided on one side of the vertical plate, and a second electric telescopic rod is provided on one side of the inclined plate.

[0011] Furthermore, the clamping component includes a third slide rail, a second motor, a bidirectional lead screw, and a clamping plate.

[0012] Furthermore, the second motor is disposed on one side of the third slide rail, the bidirectional lead screw is connected to the main shaft end of the second motor, the clamping plate is threadedly sleeved with the bidirectional lead screw, and the third slide rail is connected to the telescopic end of the second electric telescopic rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses indicator lights to indicate the replacement status of the tray. After the new tray is replaced, the clamping component pulls the replaced tray outward, and the corresponding pick-and-place machine station code is pushed forward. Then, under the action of the driving component, the scanning and detection equipment scans and detects the pick-and-place machine station code and the material label on the tray. The detection does not require manual scanning, which not only reduces the labor intensity of workers, but also prevents the omission of detection and further avoids the situation of incorrect material picking.

[0024] like Figure 1-4As shown, the SMT intelligent error-proof material handling and feeding device includes a tray placement rack 1 and a frame 2. Multiple indicator lights 3 are installed on one side of the frame 2. Below each indicator light 3 is a first electric telescopic rod 4. The telescopic end of the first electric telescopic rod 4 is connected to a fixing plate 401. A pick-and-place machine station code 402 is installed on one side of the fixing plate 401. Multiple evenly arranged partitions 101 are installed on the tray placement rack 1, forming placement cavities for the tray bodies 8. The placement cavities correspond one-to-one with the positions of the indicator lights 3. On adjacent sides of the tray placement rack 1, position adjustment components for adjusting the position of the tray bodies 8 and detection components for scanning and detecting material labels on the tray bodies 8 are respectively provided. The position adjustment components include a second drive component that drives the clamping component 7 to move, and the detection components include a drive component 6 that drives the scanning and detection device 9 to move. Specifically, the indicator lights 3 correspond to the positions of the tray bodies 8. When an old tray is used up and a new tray is replaced... When the conveying structure at that location needs to be stopped, indicator light 3 will illuminate. After a new tray is replaced, the detection component will successfully scan and detect the material label on the new tray and the pick-and-place machine station code 402 at that location. Then, indicator light 3 will turn off, and the conveying structure at that location will drive the new tray to be conveyed and loaded. During the scanning and detection, the clamping component 7 can clamp the tray body 8 outward, and the scanning and detection device 9 can scan and detect the material label on it. Then, the first electric telescopic rod 4 extends and pushes the fixed plate 401 at the corresponding location to extend. Under the action of the second driving component, the scanning and detection device 9 can be driven to move, thus moving it to the position of the extended pick-and-place machine station code 402 for scanning and detection. During the detection, manual scanning and detection is not required, which not only reduces the labor intensity of workers, but also prevents the occurrence of missed detections and further avoids the situation of incorrect material picking.

[0025] like Figure 1 As shown, the driving component 6 includes a second slide rail 601, a first motor 602, a first slider 603, a lead screw 604, a connecting plate 605, and a third electric telescopic rod 606.

[0026] like Figure 1As shown, the first motor 602 is located on one side of the second slide rail 601, the first slider 603 is slidably located inside the second slide rail 601, the lead screw 604 is connected to the main shaft end of the first motor 602, the first slider 603 is threaded onto the lead screw 604, the connecting plate 605 is located at the top of the first slider 603, the third electric telescopic rod 606 is located on one side of the connecting plate 605, and the scanning and detection device 9 is connected to the telescopic end of the third electric telescopic rod 606. Specifically, the operation of the first motor 602 can drive the lead screw 604 to rotate, thereby driving the scanning and detection device 9 to translate along the direction of the second slide rail 601. The extension and retraction of the third electric telescopic rod 606 can drive the scanning and detection device 9 to translate along its extension and retraction direction. For different feeding positions, an encoder can be used to control its extension and retraction length in the early stage. It is electrically connected to the indicator light 3. According to the indication signal of the indicator light 3, the third electric telescopic rod 606 can be driven to extend by a corresponding length.

[0027] like Figure 1 and 2 As shown, the second driving component includes a first slide rail 5 and a vertical plate 501 slidably disposed above the first slide rail 5. An inclined plate 502 is provided on one side of the vertical plate 501, and a second electric telescopic rod 503 is provided on one side of the inclined plate 502. Specifically, the driving structure of the second driving component is the same as that in the driving component 6 as shown in the attached figure, so it will not be described in detail here.

[0028] like Figure 3 As shown, the clamping component 7 includes a third slide rail 701, a second motor 702, a bidirectional lead screw 703, and a clamping plate 704.

[0029] like Figure 3 As shown, the second motor 702 is located on one side of the third slide rail 701. The bidirectional lead screw 703 is connected to the main shaft end of the second motor 702. The clamping plate 704 is threadedly connected to the bidirectional lead screw 703. The third slide rail 701 is connected to the telescopic end of the second electric telescopic rod 503. Specifically, the operation of the second motor 702 can drive the bidirectional lead screw 703 to rotate, thus driving the two clamping plates 704 to move closer or further apart, thereby clamping the material tray body 8. The clamping force can be controlled by an encoder, which will not be elaborated here.

[0030] In summary: Indicator light 3 corresponds to the position of the tray body 8. When the old tray is used up and a new tray is replaced, the conveying structure at that position needs to be stopped. At this time, indicator light 3 will light up. After the new tray is replaced, the detection component will successfully scan and detect the material label on the new tray and the pick-and-place machine station code 402 at that position. Then, indicator light 3 will turn off, and the conveying structure at that position will drive the new tray to be conveyed and loaded. During the scanning and detection, the clamping component 7 can clamp the tray body 8 outward, and the scanning and detection device 9 can scan and detect the material label on it. Then, the first electric telescopic rod 4 extends and pushes the fixed plate 401 at the corresponding position to extend. Under the action of the second driving component, the scanning and detection device 9 can be driven to move, so that it can be moved to the position of the extended pick-and-place machine station code 402 for scanning and detection. During the detection, manual scanning and detection is not required, which not only reduces the labor intensity of workers, but also prevents the omission of detection and further avoids the situation of incorrect material picking.
