[0002] The feeder is an important component of the placement machine, also known as the feeder, which is used to feed materials accurately and quickly and deliver electronic components to the placement position.
[0003] Traditional SMT feeders have numerous shortcomings. First, they lack effective collection measures for film scrap from strips, causing it to fly or fall to the ground. This not only pollutes the production environment but also easily mixes with products or equipment components, affecting product quality and increasing the risk of equipment failure. Second, they are poorly adapted to the placement of tall pins, making it difficult to meet the diverse placement requirements of modern electronic components. As electronic devices continue to miniaturize and increase their performance, the height and shape of electronic component pins have become increasingly diverse. Traditional feeders are unable to accurately and reliably handle tall pins, resulting in decreased placement accuracy and increased scrap rates, severely hindering both efficiency and cost control.

The control device 22 controls the first motor 31, the second motor 32 and the third motor 41 through the circuit board 21 to adjust the speed, start and pause of the equipment.
[0059] Among them, a clamping assembly 6 is also provided on the shell 1, and the clamping assembly 6 includes a first spring member 61 and a clamping member 62.

[0060] Among them, a movable component 7 is also provided on the shell 1, and the movable component 7 includes a second gear component 71, a second spring and a movable component 73.

The second spring component 72 is not deformed, and the second gear component 71 is engaged with the first gear component 44 to prevent the waste film from falling out.
[0061] Working principle: Preliminary preparation and equipment inspection: Turn on the power supply of the placement machine feeder, and the control device 22 in the control component 2 initializes the first motor 31, the second motor 32 and the third motor 41 for self-inspection to ensure that the motors can operate normally, check the feeding pipe 14 and the waste bin 5, remove any foreign matter that may exist, and ensure that the material and waste transmission paths are unobstructed.
[0062] Preparation of material strips and adhesive film: Take the material strip containing the material to be mounted, carefully tear off the adhesive film covering the material, and align one end of the torn adhesive film with the gap between the first gear member 44 and the second gear member 71. At this time, press the movable member 73 of the movable assembly 7 to compress and deform the second spring member 72. The second gear member 71 is separated from the first gear member 44 by a certain distance, and the adhesive film is smoothly placed between the two. Release the movable member 73, the second spring member 72 returns to its original state, and the second gear member 71 is tightly meshed with the first gear member 44 again to stabilize the adhesive film.
[0063] Equipment startup and material strip transmission: Set the equipment operating parameters on the control device 22, such as equipment speed, placement mode, etc., and then issue a startup command. The control device 22 sends a drive signal to the first motor 31 and the second motor 32 through the circuit board 21. The first motor 31 drives the first gear body 33 on the motor shaft to rotate. The first gear body 33 engages with the second gear body 34 through the third gear 35, thereby driving the second gear body 34 to rotate. The fourth gear 36 installed at the bottom of the first gear body 33 rotates accordingly, pushing the material strip to move forward at a constant speed in the feeding pipe 14.
[0064] High-leg material placement: As the material strips continue to move, when the high-leg material reaches the placement station, the placement head of the placement machine accurately grabs the material and places it at the designated position of the target circuit board 21 according to the preset program. During the entire placement process, the first transmission component 3 continuously and stably transports the material strips to ensure the continuity of material supply, ensure the placement accuracy of the high-leg material, and meet the production process requirements.
[0065] Transmission and collection of waste film: During the material strip conveying process, the waste film is continuously transmitted toward the waste bin 5 driven by the first gear member 44 and the second gear member 71. The third motor 41 drives the fifth gear 42 to rotate, and the fifth gear 42 engages with the sixth gear 43, further providing power for the transmission of the waste film, so that the waste film can smoothly enter the waste bin 5. The waste bin 5 collects and stores the waste film to prevent the waste from being scattered in the working area, keep the production environment clean, and avoid waste from contaminating or damaging production equipment and products.
[0066] Equipment pause and stop operation: During the production process, if it is necessary to pause the operation of the equipment, the operation can be performed on the control device 22. The control device 22 sends a stop signal to each motor through the circuit board 21, the motor stops running, and the equipment pauses. After all the placement tasks are completed, a stop command is issued and the equipment stops running. Before turning off the power, clean the waste in the waste bin 5 for next use.
