Description

Technical Field

[0002] With the advancement of electronic technology and the rapid development of the electronic product manufacturing industry, the processing technology of mounting electronic components on circuit boards is increasingly being adopted by many electronic manufacturers.

[0003] At present, most SMD components are packaged in the form of tape and reel. When in use, the electronic components packaged in the tape are sent to the placement head in a certain order by a special feeder to be extracted. Before use, the bag must be unpacked, the material must be pushed, the position must be aligned, and the bag must be sealed, which brings inconvenience to the SMD operation. After use, the material of the tape cannot be recycled, which is not only costly but also wastes materials.

[0004] Therefore, existing patch components cannot be directly mounted on the circuit board after being fed and sorted from bulk materials, but need to go through the processes of winding, packaging, unwinding, and pushing before being mounted on the circuit board. This process increases the number of patch steps, increases the cost of patching, reduces work efficiency, and also causes waste of tape materials. Therefore, it needs to be improved.

The discharging mechanism 6 is used to transport the bulk materials transported by the manipulator 5 to the feeding place of the SMT machine according to the requirements of the SMT machine. The control mechanism 7 is connected to the feeding mechanism 2, the disc transfer mechanism 3, the cross-transport mechanism 4, the manipulator 5 and the discharging mechanism 6. The control mechanism 7 is used to control the feeding mechanism 2, the disc transfer mechanism 3, the cross-transport mechanism 4, the manipulator 5 and the discharging mechanism 6 to work in sequence.

[0029] In this embodiment, the frame 1 is L-shaped as a whole, and six support legs 8 are provided at the bottom of the frame 1, which are used to support the frame 1 when the frame 1 is in use. At the same time, four universal wheels 9 are also provided at the bottom of the frame 1. When the bulk material supply device needs to be moved or adjusted in position, the frame 1 is supported by the universal wheels 9, thereby facilitating the movement or position adjustment of the bulk material supply device.

[0030] Furthermore, if Figure 2-4 As shown, the cross transport mechanism 4 includes: a transport frame 10 , a first slide rail 11 , a second slide rail 12 , a first transport device 13 , a second transport device 14 , a first driving device 15 and a second driving device 16 .

[0031] Specifically, the transport rack 10 is fixedly mounted on the bearing surface of the frame 1 by fastening screws. And the transport rack 10 spans between the disc transfer mechanism 3 and the manipulator 5. The first slide rail 11 is fixedly mounted on the transport rack 10 away from the bearing surface (top) by fastening screws.

The second transport device 14 is slidably mounted on the second slide rail 12, and the second transport device 14 can move back and forth between the manipulator 5 and the disc transfer mechanism 3. The second transport device 14 is used to receive the bulk materials transported by the disc transfer mechanism 3, and arrange the bulk materials neatly into groups and then transport them to the material-retrieving location of the manipulator 5.

[0032] It should be noted that the second conveying device 14 and the first conveying device 13 cross-convey the bulk materials transferred by the disc transfer mechanism 3. When the first conveying device 13 is located at one end of the disc transfer mechanism 3, the second conveying device 14 is located at the material-taking location of the manipulator 5. When the first conveying device 13 slides from the side of the disc transfer mechanism 3 to the side of the manipulator 5, the second conveying device 14 slides from the side of the manipulator 5 to the side of the disc transfer mechanism 3. When the first conveying device 13 and the second conveying device 14 meet midway, the second conveying device 14 can adjust its position under the control of the control mechanism 7, thereby realizing cross-conveyance of bulk materials. The provision of two conveying devices can greatly improve the conveying efficiency of the cross-conveyance mechanism 3, thereby improving the supply efficiency of the bulk material supply equipment.

[0033] Furthermore, if Figure 2-4As shown, the first conveying device 13 includes: a first slider 17, a first mounting plate 18 and a first component carrier 19.

The first driving block 23 is sleeved on the first screw rod 21 and cooperates with the first screw rod 21. When the first screw rod 21 rotates, the first driving block 23 can reciprocate along the axial direction of the first screw rod 21.

The manipulator 51 is driven by a screw slider mechanism, and a detection element is provided on the manipulator 5, which is used to detect the position information of the manipulator 51, and send the position information to the control mechanism 7, so that the control mechanism 7 can control the overall orderly operation of the equipment.

[0050] The working principle of this embodiment is roughly as follows: after using the above-mentioned bulk material supply equipment for the placement machine, the bulk material to be placed on the placement machine can be placed on the vibration plate, and the buffered bulk material can be placed on the buffer 47 to be added when there is a lack of bulk material in the vibration plate. After the bulk materials enter the vibration disk, the vibration disk arranges them neatly and sends them to the disc transfer mechanism 3. The disc transfer mechanism 3 places the bulk materials one by one in the placement holes 42 on the first component carrier 19 or the second component carrier 27, and the corresponding first transfer device and the second transfer device cross-send the bulk materials to the manipulator 5. The manipulator 5 transfers the bulk materials on the first component carrier 19 or the second component carrier 27 as a group to the third component carrier 45 of the discharge mechanism 6, and finally sends the neatly arranged components on the third component carrier 45 to the feed port of the placement machine through the belt conveyor body, so as to realize the bulk material supply of the placement machine. The bulk material supply equipment for the placement machine set in this way breaks the feeding method of the traditional placement machine, avoids the waste of braiding materials, reduces the cost of placement, improves the efficiency of placement, simplifies the placement process, and has the advantages of simple placement process, low placement cost and high bulk material supply efficiency.

Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
