Description

Technical Field

[0001] The invention relates to the technical field of material tray transfer, and in particular to a SMT material tray transfer method. Background Art

[0002] SMT patch refers to the abbreviation of a series of process flows for processing on PCB boards. PCB (Printed Circuit Board) is a printed circuit board. SMT is surface mounting technology, which is the most popular technology and process in the electronic assembly industry.

[0003] In the existing SMT production and processing process, the material tray of the feeding station conveys the material tape to the placement machine, and the placement machine completes the placement work. When the material tape in the old material tray of the feeding station is about to run out, the operator needs to remove the old material tray from the feeding station, take out the new material tray, and connect the material tape head of the new material tray and the material tape tail of the old material tray through the material receiving machine, and then place the new material tray at the feeding station to continue the material feeding of the old material tray. At the same time, before joining, the blank part of the tail end of the old material tray needs to be cut off and then joined. Manual operation of blank cutting and joining relies on manual judgment, has a high error rate, and is cumbersome to operate, which not only has low work efficiency, but also increases production costs. Summary of the invention

[0004] In view of the above problems, the present invention provides an SMT material tray transfer method, which enables the material tray to be replenished by automatic cutting, splicing and automatic loading of new material trays when the material tape is about to be exhausted. It has a high degree of automation and high accuracy, thereby reducing production costs.

[0006] After the old material tray on the SMT trolley that needs to be replenished is pushed out, the old material tray is taken away from the SMT trolley by the transfer robot, and the old material belt is brought into the material receiving flow channel of the material receiving mechanism, and the excess part of the old material belt is brought into the buffer bin, so that the material belt can ensure the normal operation of the SMT trolley during the transfer process. At the same time, the CCD of the tail shearing mechanism detects the empty tail belt, the tail cutting mechanism cuts off the empty tail belt, and the old material tray is transferred to the empty tray placement mechanism;

[0007] The new material tray is lifted by the lifting mechanism, and then the new material tray enters the feeding channel through the material belt driving mechanism, and stops after the CCD detects the empty material belt position at the head. The tail end of the old material belt and the head end of the new material belt are sent to the material receiving mechanism at the same time, and the head and tail material belts are bonded together;

[0008] The transfer robot then takes out the new material tray, and the receiving motor starts receiving the material, placing the new material tray at the corresponding loading position on the SMT trolley that needs to be replenished.

[0009] It is further characterized in that it comprises the following specific steps:

[0010] S1. Prepare the material tray for the placement machine in the material basket and place the material basket at the buffer station;

[0011] S2, automatically moves the material basket to the loading platform of the material receiving machine;

[0014] S5, the transfer robot moves to the position where the new material tray is on the line, the scanner scans the confirmation information, the lifting mechanism lowers the new material tray to make way, and at the same time the push-pull module of the placement machine trolley pushes out the material box to be refilled;

[0015] S6, the transfer robot moves to the position of the placement machine trolley, scans and confirms the old material tray information, and takes a photo again to confirm the position of the old material tray;

[0016] S7, the buffer bin is rotated and aligned, the robot takes out the old material tray from the bin of the placement machine trolley, and puts the old material belt into the material receiving channel;

[0017] S8, the buffer pressing mechanism acts to limit the flow direction of the old material tape, and the winding motor on the transfer robot feeds in the reverse direction, so that the old material tape is buffered into the buffer bin without affecting the feeding of the placement machine trolley. After the CCD on the tail material buffer module detects the tail empty material tape position, the winding motor stops, and the transfer robot places the empty material tray to a fixed position;

[0018] S9, the tail material cutting mechanism cuts off the tail empty material strip;

[0019] S10, the lifting mechanism lifts the new material tray and docks it with the feeding channel, and feeds the material through the material belt driving mechanism until the corresponding CCD detects the material belt position of the head and stops the driving operation of the material belt driving mechanism;

[0027] It is further characterized by:

[0028] There are several groups of material boxes arranged along a straight line in the material basket. Each material box is driven up by the lifting mechanism, and then the material tray is separated from the material box by the material tray clamp. Then the material box is lowered to the corresponding position of the material basket by the lifting mechanism. The entire material basket moves in a straight line driven by the linear drive mechanism until all the material trays in the material boxes are transferred. Then, the empty material basket is transferred out by the external transfer mechanism and transported into a new material basket.

[0029] After the empty trays of the empty tray placing mechanism are filled, the external transfer mechanism simultaneously takes away the empty trays on the empty tray placing mechanism.

[0030] After adopting the above technical scheme, after the material tray on the SMT trolley has operated for the set time and the system senses that the material on the material tray is about to run out, the SMT trolley will push out the corresponding material tray, and through the movement of the transfer robot and the action of its material tray clamp, the old material tray will be transferred to the transfer bin, and the old material belt will be placed on the material receiving channel, and the old material tray will be transferred to the empty material tray placement mechanism, and then the new material tray will be replenished, and the new material belt will be connected to the material receiving channel. After cutting off the empty material belt at the tail, the material belt is connected through the material receiving mechanism, and then the new material tray is placed on the corresponding material tray position of the SMT trolley through the transfer robot, and the system continues to operate reliably. It enables the material tray to be replenished through automatic cutting, connecting and automatic loading of the new material tray after the material belt is about to run out. It has a high degree of automation and high accuracy, which reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS
