Description

Technical Field

[0001] The present application relates to the technical field of chip placement machines, and in particular to a material stabilizing structure and a feeder. Background Art

[0002] The component feeding device in current SMT processes is called a feeder. As feeding speeds continue to increase, excessively fast feeding can easily cause the material to tip over, leading to suction failure. Traditionally, a permanent magnetic spacer has been added to hold the material in place and prevent it from tipping over.

[0003] However, the demand for faster and faster feeding speeds and the fixed feeding stroke require high speeds and accelerations, which can easily cause components to flip over and fly out, preventing them from being picked up, leading to suction failure. If the magnetism of the permanent magnetic material gasket is too weak, it will not be attracted. If it is too strong, the material will easily be attracted to the magnet, preventing the vacuum nozzle from successfully picking up the material. Utility Model Content

[0019] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0020] The component feeding device in current SMT processes is called a feeder. As feeding speeds continue to increase, excessively fast feeding can easily cause the material to tip over, leading to suction failure. Traditionally, a permanent magnetic spacer has been added to hold the material in place and prevent it from tipping over.

[0021] However, the demand for faster and faster feeding speeds and the fixed feeding stroke require high speeds and accelerations, which can easily cause components to flip over and fly out, preventing them from being picked up, leading to suction failure. If the magnetism of the permanent magnetic material gasket is too weak, it will not be attracted. If it is too strong, the material will easily be attracted to the magnet, preventing the vacuum nozzle from successfully picking up the material.

[0022] In one of the implementation methods, a material stabilizing structure is provided, and an electromagnet adsorption device is provided at the delivery position of the feeder material strip 10, the electromagnet adsorption device includes an electromagnet adsorption block 20, a wire and a controller, the controller is provided on the feeder control PCB, the electromagnet adsorption block 20 is connected to the controller through a wire, the electromagnet adsorption block 20 is provided at the delivery position of the feeder material strip 10, and the electromagnet adsorption block 20 is provided with an adsorption surface 21, and the adsorption surface 21 is attached to the bottom of the material strip 10.

[0023] It should be noted that the electromagnet suction device at the delivery point of the material strip 10 ensures the stability and accuracy of the material on the material strip 10 during the transfer process. The material can be electronic components. During the delivery process, the material on the material strip 10 is firmly attached to the material strip 10 by the suction surface 21 of the electromagnet suction block 20 at the bottom of the material strip 10, preventing it from falling. When the delivery is completed, the electromagnet is turned off to allow the suction nozzle to pick up the material.

[0024] According to the material stabilizing structure and feeder provided by the present invention, the beneficial effects are as follows: first, an electromagnet adsorption device is provided at the feeder strip 10 delivery position, wherein the electromagnet adsorption device includes an electromagnet adsorption block 20, a wire and a controller, the controller is provided on the feeder control PCB, the electromagnet adsorption block 20 is connected to the controller via a wire, the electromagnet adsorption block 20 is provided at the feeder strip 10 delivery position, and the electromagnet adsorption block 20 is provided with an adsorption surface 21, and the adsorption surface 21 is attached to the bottom of the strip 10; before the start of feeding, the electromagnet adsorption device is opened by the controller so that the electromagnet adsorption block 20 of the electromagnet adsorption device can adsorb the material by magnetic attraction, and when the feeding action is completed, the electromagnet adsorption device is closed by the controller, so that the suction nozzle can adsorb the material smoothly. The magnetic material of the present application is not permanently magnetic, and the electromagnet adsorption block 20 can turn off the magnetic force through the controller to ensure the magnetic attraction during the feeding process, and turn off the electromagnet adsorption block 20 when the feeding is completed to avoid the magnetic force being too strong and causing the suction nozzle to be unable to absorb.

[0025] In one implementation, the adsorption surface 21 of the electromagnet adsorption block 20 covers at least two material slots 11 of the material strips 10 .

[0026] It should be noted that multiple materials can be fixed at the same time.

[0027] In one implementation, the electromagnet adsorption block 20 further includes an avoidance groove, which is located on the travel path of the material trough 11, and the upper part of the avoidance groove corresponds to the suction nozzle.

[0028] It should be noted that the avoidance groove is located on the travel path of the material trough 11, which can ensure that when the material is sucked by the suction nozzle and moves upward, the electromagnet adsorption block 20 will not hinder the movement of the material, prevent the suction nozzle from colliding or rubbing with the electromagnet adsorption block 20, and ensure the smooth feeding process.

[0029] In one implementation, the adsorption surface 21 of the electromagnet adsorption block 20 ends in front of the adsorption position of the suction nozzle, and the front of the adsorption position of the suction nozzle refers to the opposite direction of the moving direction of the material belt 10.

[0030] It should be noted that when the electromagnet adsorption block 20 releases the material, it stops adsorbing the material before the suction nozzle is ready to adsorb the material, ensuring that the suction nozzle contacts and adsorbs the material without any obstruction, thereby improving the accuracy and success rate of adsorption.

[0031] In one implementation, the electromagnet adsorption block 20 includes an adsorption frame and an electromagnet, and the electromagnet is fixed in the adsorption frame.

[0032] It should be noted that the adsorption frame provides a stable support for the electromagnet, enabling it to maintain a fixed position and shape, so that the electromagnet will not be displaced or deformed during operation.

[0033] In one implementation manner, the adsorption frame includes a support frame, and the upper portion of the support frame corresponds to the suction nozzle.

[0034] In one implementation, the electromagnet adsorption block 20 includes an adsorption frame and at least a first electromagnet and a second electromagnet. The first electromagnet and the second electromagnet are arranged in sequence below the travel path of the material strip 10 according to the travel direction of the material strip 10. The first electromagnet and the second electromagnet are respectively connected to the controller through wires, and the controller can control the switches of the first electromagnet and the second electromagnet respectively.

[0035] It should be noted that specific electromagnets can be selectively activated or deactivated based on the actual position and state of the material. This ensures that materials that have not yet reached the suction nozzle position can be firmly adsorbed on the material belt 10, while materials that have reached the suction nozzle position are adsorbed by the suction nozzle in a non-magnetic state. Each electromagnet is connected to the controller via an independent wire. The controller can control the switching state of the first and second electromagnets separately without affecting the other electromagnets at the same time. The ability to independently control provides the equipment with greater flexibility and precision. This design ensures effective contact between the electromagnet and the material, improving the reliability and efficiency of adsorption.

[0036] In one implementation, a weight detection device is also included.

[0037] It should be noted that by testing the weight of the material, it is ensured that the material adsorbed each time meets the preset standards.

[0038] In a second aspect, a feeder is provided, comprising the material stabilizing structure described in any one of the first aspects.

[0039] According to the feeder provided by the present invention, the beneficial effects are as follows: first, an electromagnet adsorption device is provided at the feeder strip 10 delivery position, wherein the electromagnet adsorption device includes an electromagnet adsorption block 20, a wire and a controller, the controller is provided on the feeder control PCB, the electromagnet adsorption block 20 is connected to the controller via a wire, the electromagnet adsorption block 20 is provided at the feeder strip 10 delivery position, and the electromagnet adsorption block 20 is provided with an adsorption surface 21, and the adsorption surface 21 is attached to the bottom of the strip 10; before the start of feeding, the electromagnet adsorption device is opened by the controller so that the electromagnet adsorption block 20 of the electromagnet adsorption device can adsorb the material by magnetic attraction, and when the feeding action is completed, the electromagnet adsorption device is closed by the controller, so that the suction nozzle can adsorb the material smoothly. The magnetic material of the present application is not permanently magnetic, and the electromagnet adsorption block 20 can turn off the magnetic force through the controller to ensure the magnetic attraction during the feeding process, and turn off the electromagnet adsorption block 20 when the feeding is completed to avoid the magnetic force being too strong and causing the suction nozzle to be unable to absorb.
