Description

Technical Field

[0001] The utility model relates to auxiliary production equipment of a chip mounter, in particular to a chip component feeding device. Background Art

[0002] Some existing chip placement machines need to be provided with chip components through a feeding device. The feeding device mainly includes a vibration plate, which arranges the chip components into a queue to supply them to the chip placement machine. For some chip components, such as LED chips, the front side is a lens and the back side is a pin. The feeding device needs to turn the front side up when discharging. Some existing feeding devices usually set a rejection mechanism on the vibration plate, and set a front and back detector to detect the front and back of the chip components in the arrangement channel of the vibration plate. The front and back detector is, for example, an optical fiber probe or a visual detection device. When the front and back detector detects that there is a chip component with the back side facing up in the queue of the arrangement channel of the vibration plate, the rejection mechanism is controlled by the control host. The rejection mechanism removes the chip component in the arrangement channel and puts it into the waiting cavity of the vibration plate for re-queueing. Through the above-mentioned repeated rejection and rearrangement, the chip components can be output to the outside in a queue with the front side facing up. However, the above-mentioned feeding device has very high requirements on the timing of the rejection mechanism to reject the patch components because the queue of the patch components in the vibration disk is constantly moving. If the rejection mechanism fails to reject the patch components with the reverse side facing up and return them to the vibration disk for rearrangement in time, the patch components will be mixed into the queue and output to the outside, which will affect the normal operation of the subsequent patch machine.

[0039] Reference Figures 1 to 9 , a chip component feeding device, which includes: a machine base 100, a vibration plate 200, a main positive and negative detector 300, a rejection mechanism 400, a control host, a linear output component 500, a secondary positive and negative detector 600 and an alarm. The vibration plate 200 is arranged on the machine base 100, and the vibration plate 200 is provided with a cavity 210 to be discharged and an arrangement channel 220, and the arrangement channel 220 is provided with a queue output end 221. The main positive and negative detector 300 is arranged on the vibration plate 200, and the main positive and negative detector 300 is used to detect the positive and negative of the workpiece in the arrangement channel 220. The rejection mechanism 400 is arranged on the vibration plate 200, and the rejection mechanism 400 is used to reject the workpiece with the reverse side facing up in the arrangement channel 220 and return it to the cavity 210 to be discharged. The control host is used to control the operation of the chip component feeding device, and the main positive and negative detector 300 and the rejection mechanism 400 are connected to the control host. The linear output component 500 is arranged on the machine base 100, and the linear output component 500 is provided with a linear output material channel 510. One end of the linear output material channel 510 is connected to the queue output end 221 of the vibration disk 200, and the other end of the linear output material channel 510 is the output end. The secondary positive and negative detector 600 is arranged on the machine base 100, and the secondary positive and negative detector 600 is opposite to the linear output material channel 510 and is used to detect the positive and negative of the workpiece in the linear output material channel 510. The secondary positive and negative detector 600 and the alarm are connected to the control host. The secondary positive and negative detector 600 is used to control the shutdown of the patch component feeding device and control the alarm to alarm.

[0040] When the device is operating, SMD components are poured into the discharge cavity 210 of the vibration plate 200. The vibration plate 200 arranges the SMD components into the arrangement channel 220. When the main positive and negative detector 300 finds a SMD component with the reverse side facing up, the host computer controls the rejection mechanism 400 to remove the SMD component with the reverse side facing up and return it to the discharge cavity 210 for rearrangement. The arranged SMD components are continuously output through the linear output channel 510 of the linear output assembly 500 and undergo a secondary inspection through the secondary positive and negative detector 600. When a SMD component with the reverse side facing up is detected, the host computer controls the device to shut down and an alarm is sounded, reminding the worker to remove the SMD component with the reverse side facing up to prevent it from being mixed into the subsequent queue.

[0041] The above-mentioned chip component feeding device adds a secondary positive and negative detector 600 at the corresponding straight output material channel 510, and uses the secondary positive and negative detector 600 to check the positive and negative sides of the chip components in the output queue. When a chip component with the reverse side facing up appears, the machine can be stopped in time and the worker can be reminded to take it away, which can better avoid outputting chip components with the reverse side facing up.

[0042] In this embodiment, multiple main front and back detectors 300 are provided and arranged in sequence along the arrangement channel 220, and the rejection mechanism 400 is provided in a one-to-one correspondence with the main front and back detectors 300. By providing multiple main front and back detectors 300 and rejection mechanisms 400, multiple inspections can be ensured, further reducing the occurrence of SMD components with the reverse side facing up.

[0043] In the embodiment, a total of three groups of main positive and negative detectors 300 and rejection mechanisms 400 are provided. Of course, it is conceivable that the main positive and negative detectors 300 and rejection mechanisms 400 are not limited to three groups. For example, there can be two groups or more than three groups, and the specific configuration can be based on actual conditions.

[0044] In the embodiment, a blow hole 242 is provided on the side wall of the arrangement channel 220 facing away from the cavity 210 to be discharged. The blow hole 242 faces the cavity 210 to be discharged. The rejection mechanism 400 is a blow structure comprising a compressed air source, a compressed air input pipe, and a control valve. The blow hole 242 is connected to the compressed air source via the compressed air input pipe. The control valve is connected to the control host and is used to control the compressed air source to supply and cut off air to the compressed air input pipe. When it is necessary to reject a patch component with the reverse side facing up, when it moves to a position opposite the blow hole 242, the control valve is opened, allowing the compressed air source to be blown out through the blow hole 242, blowing the patch component back into the cavity 210 to be discharged. The use of the above-mentioned rejection mechanism 400 has a simple structure and is easy to implement.

[0045] It is conceivable that the rejection mechanism 400 is not limited to the above-mentioned implementation mode. For example, a vacuum suction cup gripper provided on the machine base 100 can be used to directly grab the patch components and send them back to the cavity to be discharged 210, or some pushing mechanisms can be used to push the patch components back to the cavity to be discharged 210.

[0046] In the embodiment, the arrangement channel 220 is provided with a height difference step 222. After the workpiece in the arrangement channel 220 passes through the height difference step 222, a height difference is formed with the workpiece behind it. The height difference step 222 is provided corresponding to the air blow hole 242, so that when the workpiece moves to the air blow hole 242, a height difference is formed with the workpiece behind it. The above structure can form a height difference between the patch components in the queue passing through the air blow hole 242 and the patch components behind it, so that when the air blows through the air blow hole 242, the patch components can be better blown back to the cavity 210 to be discharged, avoiding the influence of the patch components behind it.

[0047] In this embodiment, a detection hole 243 is formed next to the air hole 242, and the detection hole 243 faces the arrangement channel 220. The main front and back detector 300 is provided with a main detection probe, which is installed on the vibration plate 200 and detects the workpiece in the arrangement channel 220 through the detection hole 243. The above structure is compact, and the main front and back detector 300 can be closer to the workpiece for detection, thereby improving detection accuracy.

[0048] In the embodiment, the vibration plate 200 includes a main body 230 and an embedded block 240. The main body 230 is provided with a default portion on one side of the arrangement channel 220. The default portion is located on the side of the arrangement channel 220 away from the discharge cavity 210. The embedded block 240 is installed on the default portion. The embedded block 240 is provided with a constituting surface 241 that constitutes a part of the side wall of the arrangement channel 220. The blowing hole 242 and the detection hole 243 are opened on the constituting surface 241.

[0049] In an embodiment, the main detection probe can be a fiber optic probe, which uses the difference in signals detected by the fiber optic probe when the chip component is placed front and back to detect the front and back of the chip component. The fiber optic probe can be used or configured to output a high-level and a low-level signal when detecting the front and back of the chip component. The control host determines the front and back based on the level signal and outputs a control level to activate the rejection mechanism 400 to reject the chip component. Of course, it is conceivable that the main detection probe is not limited to using a fiber optic probe. For example, if the main front and back detector 300 uses a visual detection device, then the main detection probe can also be a camera. The visual detection device can determine the front and back by capturing images and performing visual analysis. When a visual detection device is used, the main front and back detector 300 can also be installed on the machine base 100 so that the camera of the visual detection device faces the vibration disk 200 to capture. It is understandable that in the prior art, there are many implementation methods for performing front and back detection and rejection of components in the vibration disk 200. Those skilled in the art can reasonably configure this part of the structure according to actual conditions and are not limited to the above-mentioned implementation methods.

[0050] In an embodiment, a cover plate 520 is provided at the middle front section of the linear output channel 510. The cover plate 520 is provided with a secondary detection opening 521 connected to the linear output channel 510. The secondary positive and negative detector 600 is provided with a secondary detection head. The secondary detection head is provided on the upper side of the linear output channel 510 and opposite to the secondary detection opening 521. Alternatively, in other embodiments, a secondary detection opening 521 is provided on the bottom wall of the linear output channel 510. The secondary positive and negative detector 600 is provided with a secondary detection head. The secondary detection head is provided on the lower side of the linear output channel 510 and opposite to the secondary detection opening 521. By arranging the secondary detection head of the secondary positive and negative detector 600 on the upper side or the lower side of the linear output channel 510, it is possible to directly detect the SMD components and ensure accurate detection.

[0051] In the embodiment, the secondary front and back detector 600 utilizes a visual inspection device, and the secondary inspection head is a camera. Of course, it is conceivable that the secondary front and back detector 600 is not limited to a visual inspection device; for example, a fiber optic probe or other structure capable of detecting the front and back sides of a component may also be employed. In the embodiment, the secondary front and back detector 600 is mounted to the machine base 100 via a frame. Of course, it is conceivable that the secondary front and back detector 600 may also be mounted to the linear output assembly 500.

[0052] In an embodiment, the secondary positive and negative detector 600 is used to control the shutdown of the entire device. Specifically, it can output a control level to the control host, and the control host controls the entire device to perform a shutdown operation. At the same time, it also notifies the alarm to sound an alarm. The alarm can specifically be a light alarm, a sound alarm, or a sound and light alarm.

[0053] In an embodiment, the SMD component feeding device further includes a feeding mechanism 700, which is arranged on the machine base 100. The feeding mechanism 700 includes a storage barrel 710 and an output chute 720. The storage barrel 710 is provided with a discharge end, which is opposite to the input end of the output chute 720. The output end of the output chute 720 is arranged above the cavity 210 to be discharged of the vibration disk 200. The discharge end of the storage barrel 710 is provided with a feeding switch for controlling the discharge and closing of the discharge end. The material can be stored in the storage barrel 710 first. When the vibration disk 200 needs to be replenished with SMD components, the discharge end of the storage barrel 710 is opened by the feeding switch, and the material is sent to the cavity 210 to be discharged of the vibration disk 200 through the output chute 720. In an embodiment, the output chute 720 can be connected to a straight vibrator to facilitate the pouring of the material into the cavity 210 to be discharged of the vibration disk 200. In an embodiment, the material feeding switch may adopt some valve structures or some material blocking structures.

[0054] In the embodiment, a plurality of vibration disks 200 are provided, each vibration disk 200 is provided with a main positive and negative detector 300 and a rejection mechanism 400, and the linear output assembly 500 is provided with linear output channels 510 corresponding to the vibration disks 200. The linear output channels 510 extend in the front-to-back direction and are arranged parallel to each other at intervals. The rear end of the linear output channel 510 is connected to the queue output end 221 of the corresponding vibration disk 200, and the front end of the linear output channel 510 is the output end and is aligned left and right. With the above structure, multiple columns of patch components can be neatly output, and the feeding efficiency is high.

[0055] The stopper 820 is used to drive the stopper 810 to move up and down. When the patch components move to their front end in the linear output channel 510, the blocking member driver 820 can drive the blocking member 810 to enter the docking position, and the patch components can then enter the component loading slot 822 of the workpiece loading seat 821 to be positioned and loaded. Then, the blocking member driver 820 drives the blocking member 810 to enter the blocking position, and the blocking end face 823 of the workpiece loading seat 821 blocks subsequent patch components. When the subsequent equipment has grabbed all the patch components from the component loading slot 822, the above process can be repeated. With the above structure, the patch components can be output to the outside in a convenient and orderly manner.

[0056] In an embodiment, the material stopper driver 820 may be a pneumatic cylinder or an electric cylinder, and the specific configuration may be based on actual conditions. The front end of the linear output assembly 500 may be provided with a sliding connection hole corresponding one-to-one with the workpiece loading seat 821 of the material stopper 810. The sliding connection hole is a vertically opened hole, and the workpiece loading seat 821 of the material stopper 810 is slidably provided in the sliding connection hole so as to be able to move vertically. The lower end of the material stopper 810 may be directly fixed to the action portion of the material stopper driver 820, and the material stopper driver 820 may be fixed to the linear output assembly 500.

[0057] In an embodiment, the linear output component 500 is provided with a linear vibrator 530, which is used to drive the workpiece in the linear output channel 510 to move toward the output end, thereby speeding up the discharge efficiency and avoiding stagnation of the patch components. Of course, in some embodiments, if the linear conveying path is short, it can also rely solely on the forward push of the material queue to move forward. In an embodiment, a plurality of linear vibrators 530 are provided, which drive the workpiece in the linear output channel 510 to move toward the output end at different positions. Those skilled in the art can reasonably configure the number and location of the linear vibrators 530 according to actual conditions.

[0058] In the embodiment, the vibration disk 200 includes two front vibration disks 200 and two rear vibration disks 200, the two front vibration disks 200 are opposite to each other left and right, and the queue output ends 221 of the two are located on a relatively close side, the two rear vibration disks 200 are opposite to each other left and right and are located at the rear side of the two front vibration disks 200, the two rear vibration disks 200 are opposite to each other left and right, and the queue output ends 221 of the two are located on a relatively close side, the linear output component 500 is inserted between the two front vibration disks 200 and the two rear vibration disks 200, and the linear output channel 510 includes two inner channels and two outer channels, the two inner channels are located between the two outer channels, the rear ends of the two inner channels extend to a position corresponding to the queue output ends 221 of the two rear vibration disks 200, and the rear ends of the two outer channels extend to a position corresponding to the queue output ends 221 of the two front vibration disks 200. With the above structure, multiple vibration disks 200 and linear output channels 510 can be arranged in a compact structure.

[0059] In the embodiment, the base 100 is the supporting part of each mechanism component, which can be a single base body or multiple base bodies to achieve support, and can be specifically configured according to actual conditions.

[0060] The technical features of the above embodiments can be combined arbitrarily.
