Description

Positioning mechanism for transmission system of electronic components

The invention relates to a positioning mechanism, in particular to a positioning mechanism for a transmission system of electronic components.

In order to be able to automatically transfer multiple large electronic components such as capacitors or resistors from the production end to the electronic component storage area, generally the two pins of these electronic components are attached to a conveyor belt, and then a The transmission system accomplishes this task.

The conventional transmission system includes a feed gun, a conveying part, a foot trimmer and a mechanical arm. The feeding gun is arranged at the front end of the conveying part. The foot trimmer is arranged at the rear end of the conveying part and has a cutter. The mechanical arm can move between the rear end of the conveying part and an electronic component storage area, and has a suction head or a clamping jaw. The conveyor belt moves to the feeding gun in a horizontal state, and the electronic components move to the feeding gun with the conveyor belt in a horizontal state, and move to the conveying part along the feeding gun. When the conveyor belt passes through the junction of the feeding gun and the conveying part, the conveyor belt will flip from the horizontal state to the vertical state. The conveyor belt continuously moves to the rear end of the conveying section in a gap of the conveying section in a vertical state, a body of the electronic components moves on the top of the conveying section in a vertical state, and the pins of the electronic components are in a vertical state Move to the rear end of the conveying part in the gap. The cutter of the foot trimmer cuts the pins of the electronic components with its blade. The mechanical arm sucks the electronic components through its suction head or clamps the claws, moves the electronic components upward to leave the conveying part, and then moves the electronic components to the electronic component storage area. Because the lengths of the pins of the electronic components are cut and modified by the pin cutter to comply with the IPC-610 specification, they can be used to assemble on the circuit board.

However, the body of each electronic component has a certain weight, and the pins of each electronic component are relatively slim. Therefore, before each electronic component enters the feeding gun, various factors may cause each electronic component to be shaken, thereby causing the pins of each electronic component to bend and deform.

Furthermore, the foot trimmer generates vibration force when cutting the pins of each electronic component, and the vibration force causes the entire conveyor belt to shake to a certain extent. Some electronic components that are moving along the feed gun to the conveying part are affected by the conveyor belt and also shake. In addition, the body of each electronic component has a certain weight, and the pins of each electronic component are relatively slender. The leads of some electronic components that are moving along the feeding gun to the conveying part are bent and deformed.

Such electronic components with bent and deformed pins are prone to not move smoothly and get stuck in the process of moving along the feed gun due to the bending of the pins. Once a pin is bent and deformed and the electronic component is stuck and the rear electronic component is still moving at the normal moving speed, the rear electronic component will collide and push the front stuck electronic component. This pushing action will cause the following three problems: First, the movement speed of the rear electronic components will decrease, and then all the electronic components that enter the feeding gun at the normal speed will collide and push each other into a ball. ; Second, the pins of some electronic components may collide and bend and deform during the pushing process; and third, the pins of the electronic components that have been bent and deformed have more severe bending and deformation .

Any electronic components with bent and deformed pins do not comply with the IPC-610 specification and become defective products, which are not suitable for assembly on circuit boards.

In addition, the conveying part does not have any positioning function. After the pins of the electronic components are cut by the foot cutter, the electronic components are easily affected by the cutting force of the foot cutter and tilt or fall down. Since it is difficult for the robot arm to pick up the body of each electronic component that is tilted or down with its suction head or gripper claw, the electronic component that is tilted or down will always stay at the rear end of the conveying part. The trimmer will cut the leads of the tilted or fallen electronic components again, resulting in that the length of one of the leads of the tilted or fallen electronic components is longer than the standard length of the IPC-610 standard, and is tilted or inverted. The length of the other pin of the electronic component that came down was shorter than the standard length of the IPC-610 standard, or the length of the lead of the electronic component that was tilted or fell was shorter than the standard length of the IPC-610 standard. After the leads of the tilted or fallen electronic component are cut twice, the end surface of the free end becomes a bevel. Therefore, the electronic components cannot meet the IPC-610 specification and become defective products, the height assembled on the circuit board cannot be maintained, and the wear rate of the electronic components is high.

The guiding block 114 is disposed above the base 113 and has a guiding inclined surface 1141, and the bottom of the guiding block 114 and the top of the base 113 together form a guiding space 112. The guiding inclined surface 1141 extends from the top of the front end of the guiding block 114 to the bottom of the guiding block 114, is located above the base inclined surface 1131, and forms an opening 111 together with the base inclined surface 1131. The supporting portion 12 is provided on one side of the base 113.

As shown in FIGS. 11 and 12, regardless of whether the leads 2012 of the electronic components 201 are straight or bent, the conveyor belt 200 and the leads 2012 of the electronic components 201 attached to the conveyor belt 200 Both can move smoothly along the inclined surface 1131 of the base below the opening 111 to the guiding space 112 without being squeezed into a ball. More specifically, when the pins 2012 of one of the electronic components 201 are bent and deformed, the pins 2012 of one of the electronic components 201 will be upwardly tilted relative to the body 2011, and the upwardly-turned leads 2012 will contact Go to the guide slope 1141. Because of the tapering of the opening 111, the upwardly tilted pin 2012 is gradually guided by the base inclined surface 1131 below the opening 111 and the guiding inclined surface 1141 above the opening 111 to achieve a preliminary guiding effect. After the pins 2012 of the electronic components 201 enter the alignment space 112, the upwardly tilted pins 2012 are further guided by the top of the base 113 below the alignment space 112 and above the alignment space 112 The bottom of the guiding block 114 is synchronized to a straight line.
