Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for a PCB plug-in machine, in particular to a feeding device. Background Art

[0002] In the actual application of PCB plug-in machines, it is often necessary to assemble multiple components such as capacitors and resistors of the same specifications on a single PCB board at the same time. In order to improve the plug-in efficiency, the plug-in machine usually adopts a method of taking materials with multiple chucks at the same time to reduce the time of taking materials and plug-in. Some components need to use a vibration plate to realize the loading function;

[0003] When the existing feeding device is in use, due to the relatively large size of the vibration plate feeder, for loading multiple pieces of a single component, the spacing of the chuck picking is much smaller than the size spacing of the feeder, which causes difficulties in spatial layout and is not convenient for supplying materials to two picking positions at the same time. Utility Model Content

[0004] The main purpose of the utility model is to provide a feeding device which can effectively solve the technical problem in the background technology that "for loading multiple pieces of a single component, the spacing between the chucks for picking up materials is much smaller than the size spacing of the feeder, which causes difficulties in spatial layout and is inconvenient to supply materials to two picking positions at the same time."

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A feeding device comprises a material rail, which is used to be installed on a straight vibration feeder. A reversing assembly is installed on the top of the material rail, and the reversing assembly comprises a feed channel, a first discharge channel and a second discharge channel. The first discharge channel and the second discharge channel are respectively opened on both sides of the top of the material rail near the rear end, and the feed channel is opened at the top of the material rail near the front end. A reversing disk is movably installed inside the material rail and at the intersection between the feed channel and the first and second discharge channels. A material guide channel is opened on the top of the reversing disk, and a rotary cylinder is installed at the bottom of the material rail and at the bottom rotating shaft of the reversing disk.

[0007] As a further solution of the utility model, the first discharge channel and the second discharge channel are symmetrical to each other, and the two ends of the guide channel are respectively docked and matched with the feed channel and the first discharge channel or the second discharge channel.

[0008] As a further solution of the utility model, the material guide channel is opened on the top of the reversing disk and is arranged in a curved shape, and the feed channel, the material guide channel and the first and second discharge channels are located on the same horizontal line.

[0009] As a further solution of the utility model, the reversing disc is located inside the material rail and is movably rotatable, and the reversing disc and the output shaft of the rotary cylinder are fixedly installed.

[0010] As a further solution of the present utility model, a clamping jaw cylinder is installed at the top of the material rail and at the rear position above the feeding channel, and a group of photoelectric sensors are installed outside the first discharging channel and the second discharging channel at the top of the material rail.

[0011] As a further solution of the present utility model, the claw part of the clamping jaw cylinder matches the top of the feeding channel, and the number of each group of photoelectric sensors is two.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By setting the commutation component, the clamping jaw cylinder drives the commutation disc to rotate, so that the material guiding channel is respectively docked with the feeding channel, the first discharging channel or the second discharging channel, facilitating rapid commutation for feeding, realizing the feeding requirement of a single vibrating disc to supply two picking positions simultaneously. While the cost is relatively low compared with the existing solutions, the occupied space is reduced;

[0014] By setting the clamping jaw cylinder and the photoelectric sensors, when the components in the first discharging channel or the second discharging channel are stacked to the position of the photoelectric sensors, the clamping jaw cylinder is detected and controlled to open and close the feeding channel, so that the commutation disc rotates for commutation feeding, which can block the components during commutation feeding and can automatically switch the feeding direction at the same time.

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Such as Figures 1-4As shown in the figure, a feeding device includes a material rail 1 which is used to be installed on a linear vibrating feeder. A reversing assembly 2 is installed on the top of the material rail 1. The reversing assembly 2 includes a feeding channel 3, a first discharging channel 4 and a second discharging channel 5. The first discharging channel 4 and the second discharging channel 5 are respectively arranged at both sides of the rear end of the top of the material rail 1, and the feeding channel 3 is arranged at the front end of the top of the material rail 1. A reversing disk 6 is movably installed at the intersection position inside the material rail 1 and between the feeding channel 3 and the first discharging channel 4 and the second discharging channel 5. A guiding channel 7 is opened at the top of the reversing disk 6. A rotary cylinder 8 is installed at the bottom of the material rail 1 and at the bottom rotating shaft of the reversing disk 6.

[0022] In this embodiment, the first discharging channel 4 and the second discharging channel 5 are symmetric to each other. The two ends of the guiding channel 7 are respectively docked and matched with the feeding channel 3 and the first discharging channel 4 or the second discharging channel 5. The requirements of double discharging are realized through the first discharging channel 4 and the second discharging channel 5, and the feeding of two picking positions is carried out simultaneously.

[0023] In this embodiment, the guiding channel 7 is arranged in a curved shape at the top of the reversing disk 6. The feeding channel 3, the guiding channel 7 and the first discharging channel 4 and the second discharging channel 5 are located on the same horizontal line. The reversing disk 6 drives the guiding channel 7 to rotate and reverse, so that the two ends of the guiding channel 7 are docked with the feeding channel 3 and the first discharging channel 4 or the second discharging channel 5 for reversing feeding.

[0024] In this embodiment, the reversing disk 6 is movably rotated inside the material rail 1, and the reversing disk 6 is fixedly installed with the output shaft of the rotary cylinder 8. The rotary cylinder 8 drives the reversing disk 6 to rotate, so that feeding in different directions is carried out when the feeding channel 3 feeds materials.

[0025] In this embodiment, a clamping jaw cylinder 9 is installed at the top of the material rail 1 and at the rear end position above the feeding channel 3. A group of photoelectric sensors 10 are installed outside the first discharging channel 4 and the second discharging channel 5 on the top of the material rail 1. The clamping jaw cylinder 9 is used to open and close the feeding channel 3, and the photoelectric sensors 10 are used to detect whether the components are fully fed or out of stock.

[0026] In this embodiment, the claw part of the clamping jaw cylinder 9 matches the top of the feeding channel 3. The number of each group of photoelectric sensors 10 is two. When the components are fully fed or the corresponding material channel is out of stock for a long time, the photoelectric sensors 10 detect the opposite light. The feeding channel 3 is closed by controlling the clamping jaw cylinder 9 for reversing feeding operation.

[0027] It should be noted that the present utility model is a feeding device. When in use, components enter the feeding channel 3 through the material rail 1. The material rail 1 vibrates by being installed on a linear vibratory feeder to slide-feed the components. The components enter the guiding channel 7 in the reversing disk 6 through the unclosed jaw cylinder 9. The two ends of the guiding channel 7 are respectively docked with the feeding channel 3 and the second discharging channel 5, and enter the second discharging channel 5 through the curved guiding channel 7 to feed a plug-in machine. When the position of the photoelectric sensor 10 in the component stacking channel of the second discharging channel 5 is continuously blocked, or when the components in the first discharging channel 4 reach the material shortage alarm position, the jaw cylinder 9 is triggered to clamp the components passing through and the components in front that are blocked from passing in the feeding channel 3 without panic. After a short delay, the reversing disk 6 without components staying is driven to rotate and switch by the rotary cylinder 8, so that the two ends of the guiding channel 7 are respectively docked with the feeding channel 3 and the first discharging channel 4. Subsequently, the jaw cylinder 9 opens the jaws, and the components feed the first discharging channel 4 through the reversing disk 6 after changing the direction.
