Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of surface mount equipment, in particular to a patch tray for full-automatic chip mounter. BACKGROUND

[0002] Surface Mount Technology (SMT) is the most popular technology and process in the current electronic assembly industry. SMT is a circuit connection technology that installs pinless or short lead surface mount components (SMC / SMD, also known as chip-shaped components) on the surface of a printed circuit board (PCB) or other substrate, and then welds and assembles them through reflow soldering or immersion soldering. This technology does not require drilling and inserting holes in the printed board, and directly pastes and welds surface mount components to the specified position on the printed board surface.

[0003] Currently, SMT technology is widely used in consumer electronics, communication equipment, computers, automotive electronics, medical devices, industrial control, etc. With the popularity of smart phones, tablets, Internet of Things devices, etc., the demand for SMT technology is increasing. At the same time, SMT technology is also evolving, such as ultra-high density SMT, 3D packaging technology, etc., to meet the requirements of miniaturization, multi-functionality and high reliability of electronic products. Therefore, SMT, as an advanced electronic assembly technology, has significant advantages and broad application prospects. With the continuous progress of technology and the continuous development of the market, SMT technology will play an increasingly important role in the electronics industry

[0004] Therefore, Chinese patent CN103945655B discloses a full-automatic chip mounter, which includes a bottom plate, two sides of the bottom plate are symmetrically provided with door-shaped base frames, the upper end surface of one side of the door-shaped base frames is fixedly connected with a first linear slide rail, and the upper end surface of the other side of the door-shaped base frames is fixedly connected with a first lead screw device, a second lead screw device is vertically arranged between the first lead screw device and the first linear slide rail, the second lead screw device is threadedly connected with a double-head mounting mechanism, a transmission track mechanism is vertically arranged below the door-shaped base frames, visual recognition devices and a feeding table are arranged on both sides of the transmission track mechanism, a tape feeding device is arranged on the feeding table, a suction nozzle exchange device is arranged on one side of the transmission track mechanism. The feeding device and the visual recognition device are arranged on both sides of the conveying track, which simplifies the motion trajectory of the mounting head, increases the mounting efficiency, and realizes automatic recognition and precise positioning of electronic components. By arranging suction nozzles of different sizes, electronic components of different sizes can be mounted, and the whole machine has compact structure, low cost and high mounting precision.

[0005] However, the full-automatic chip mounter disclosed above still has the technical problem of inconvenient feeding of bulk materials and the like. Specifically, when the full-automatic chip mounter disclosed above is working, if bulk products need to be mounted, the mark point position on the mechanism for fixing the to-be-mounted component is usually recognized by the chip image mechanism; after confirming the position of the chip image mechanism relative to the to-be-mounted component, the product is placed at the corresponding position of the to-be-mounted component by the chip taking mechanism. Since, when the operator is debugging, the chip image mechanism can only roughly find the position of the taking mechanism relative to the to-be-mounted component, and does not know the accurate position between the taking part in the taking mechanism for sucking the product and the to-be-mounted component. Therefore, during debugging, the accurate position between the taking part in the taking mechanism and the to-be-mounted component needs to be further determined by the naked eye manually, so as to accurately mount the product on the to-be-mounted component, which seriously affects the mounting efficiency. At the same time, it is difficult for the human to determine the position of the taking mechanism relative to the to-be-mounted component with high precision, so as to ensure the quality of the mounted PCB product.

[0027] Please refer to the following: Figs. 1 to 3 This utility model discloses a placement tray for a fully automatic placement machine, comprising: a tray base 1, an adjusting guide rail structure 2, an adjusting drive mechanism 3, a movable tray frame 4, a position sensing unit 5, an adsorption loading structure 6, and a control unit 7. The adjusting guide rail structure 2 is disposed on the tray base 1, the adjusting drive mechanism 3 is disposed within the adjusting guide rail structure 2, the movable tray frame 4 is movably connected to the adjusting guide rail structure 2, and the adjusting drive mechanism 3 is drivenly connected to the movable tray frame 4.

The adsorption loading structure 6 is disposed on the movable tray frame 4, and the control unit 7 is disposed on the tray base 1 and is controlled by the adjusting drive mechanism 3.

[0028] Specifically, when the placement tray of the fully automatic placement machine of this utility model is in operation, the tray base 1 is connected to the external placement machine, and the external placement machine can establish an electrical connection with the adjustment drive mechanism 3, the position sensing unit 5, the suction loading structure 6, and the control unit; and the placement material to be loaded is loaded onto the suction loading structure 6. Subsequently, the external placement machine can control the suction loading structure 6 to effectively limit the material to be loaded; then, by activating the adjustment drive mechanism 3, the movable tray frame 4 is driven to slide along the adjustment guide structure 2 to the target position. The position sensing unit 5 can transmit the accurate position of the suction loading structure 6 in real time, thereby enabling precise position control of the material in the suction loading structure 6; facilitating the subsequent positioning and material picking actions of the placement machine. Furthermore, the operator can also further adjust the position of the suction loading structure 6 through the control unit 7 to ensure that the material position meets the usage requirements. Therefore, this utility model provides a fully automatic chip mounter that can conveniently, accurately, and automatically adjust the material position of the chip mounter, avoiding the inaccurate positioning caused by manual material positioning by operators; thus, it solves the technical problem of how to improve the material positioning method of the fully automatic chip mounter.

[0029] Furthermore, the two adjustable guide rail structures 2 are arranged at intervals on the tray base 1. Each adjustable guide rail structure 2 has a stand 201, a linear rail 202, a positioning identification part 203, and a side guide rail 204. The stand 201 is connected to the tray base 1, the linear rail 202 is arranged on the upper part of the stand 201, a plurality of positioning identification parts 203 are evenly spaced on the side of the stand 201, and the side guide rail 204 is arranged on the side of the stand 201 opposite to the positioning identification parts 203.

[0030] Furthermore, the adjustment drive mechanism 3 is disposed between the two adjustment guide rail structures 2. The adjustment drive mechanism 3 includes a drive motor 301, a coupling 302, a lead screw structure 303, a bearing structure 304, and a lead screw nut movable connection part 305. The drive motor 301 is disposed on the pallet base 1, and the coupling 302 connects the drive motor 301 and the lead screw structure 303 respectively. The two bearing structures 304 are disposed opposite to each other on the pallet base 1, and the lead screw structure 303 is movably connected to the two bearing structures 304. The lead screw nut movable connection part 305 is movably disposed between the two lead screw structures 304, and the lead screw nut movable connection part 305 is matched and connected to the lead screw structure 303. The lead screw nut movable connection part 305 is connected to the bottom of the movable pallet frame 4.

[0031] Furthermore, the movable pallet frame 4 includes a pallet frame 401, a plurality of pallet sliding connecting blocks 402, and a plurality of pallet legs 403; the pallet frame 401 is movably disposed above the pallet base 1, the pallet frame 401 is connected to the nut movable connecting part 305, and the adsorption loading structure 6 is disposed on the pallet frame 401; the plurality of pallet sliding connecting blocks 402 are evenly distributed at the bottom of the pallet frame 401, and each pallet sliding connecting block 402 is correspondingly connected to a linear rail 202; the plurality of pallet legs 403 are evenly spaced below the pallet frame 401, and each pallet leg 403 is correspondingly connected to a side guide rail 204.

[0032] Specifically, external control equipment such as pick-and-place machines are connected to the drive motor 301, and the control unit 7 is electrically connected to the drive motor 301. Thus, the external control equipment can start the drive motor 301 according to a preset program, and the operator can also control the drive motor 301 through the control unit 7. When the drive motor 301 is powered on, it can drive the lead screw structure 303 to rotate via the coupling 302. The two bearing structures 304 support the rotation of the lead screw structure 303. When the lead screw structure 303 is driven to rotate forward or backward, the nut moving connection part 305 can reciprocate along the lead screw structure 303. Furthermore, the nut moving connection part 305 drives the movable tray frame 4 to reciprocate along the adjusting guide rail structure 2, thereby adjusting the relative position of the adsorption loading structure 6.

[0033] More specifically, the adsorption loading structure 6 is disposed on the pallet frame 401. When the pallet frame 401 moves, the pallet sliding connecting block 402 provided at its bottom can support and guide it to slide along the linear rail 202. The pallet legs 403 provided at its bottom and sides can be used to correct the position and stabilize the movement of the pallet frame 401. This is because the pallet legs 403 can be connected to the side guide rail 204 from the side of the upright 201, thereby avoiding the pallet frame 401 from shaking during movement.

[0034] Furthermore, the position sensing unit 5 includes a side connection portion 501, a position sensor 502, and a sensor cable protective sleeve 503. The side connection portion 501 is connected to the underside of the tray frame 401, and the position sensor 502 is connected to the side connection portion 501. The position sensor 502 is disposed opposite to the positioning identification portion 203, and the sensor cable protective sleeve 503 connects the position sensor 502 to the tray base 1. Specifically, the position sensor 502, located under the side connection portion 501, can move with the movement of the tray frame 401, and the sensor cable protective sleeve 503 can be used to protect the connecting cable of the position sensor 502, preventing it from wearing out and failing due to long-term dragging during the reciprocating motion of the tray frame 401.

[0035] Furthermore, the adsorption loading structure 6 includes an adsorption loading unit 601, a loading tray 602, an adsorption connection valve 603, and several toggle switches 604. The adsorption loading units 601 are evenly distributed on the loading tray 602, which is connected to the tray frame 401. The adsorption connection valve 603 is located on the side of the loading tray 602 and connected to the adsorption loading unit 601. The toggle switches 604 are evenly distributed on the tray frame 401. Specifically, an external air source is connected to the adsorption connection valve 603, thereby controlling the adsorption action of the adsorption loading unit 601 and limiting the adsorption of material placed in the adsorption loading unit 601. The toggle switches 604 allow operators to individually control the state of each adsorption loading unit 601.

[0036] Furthermore, the control unit 7 has the necessary circuit elements and control elements for the operator to individually control the drive motor 301, etc., thereby realizing operations such as emergency stop and start.

[0037] In summary, the present invention discloses a placement tray for a fully automatic placement machine, comprising a tray base 1, an adjusting guide rail structure 2, an adjusting drive mechanism 3, a movable tray frame 4, a position sensing unit 5, an adsorption loading structure 6, and a control unit 7.
