Description

Technical Field

[0001] The invention belongs to the technical field of chip mounters, and in particular relates to a continuous feeding mechanism for a chip mounter and a use method thereof. Background Art

[0002] The SMT machine, whose full name is the automatic placement machine for electronic components, is a kind of precision production equipment widely used in the modern electronic manufacturing industry. Its main function is to automatically and accurately place electronic components (such as resistors, capacitors, integrated circuits and other SMD components) on the pre-set position on the printed circuit board (PCB). It is one of the indispensable key equipment in the automated production line of electronic products. The workflow of the SMT machine mainly includes three steps: picking up components, positioning and calibrating, and placing components. First, the nozzle of the SMT machine will pick up the specified electronic components from the feeder, and then accurately position and calibrate them through the visual system or mechanical positioning system, and finally accurately place the components on the corresponding pads of the PCB board. The continuous feeder for the SMT machine is also called a continuous feeder, which is mainly used in the SMT production line to provide a continuous and stable supply of electronic components for the SMT machine. The characteristic of this type of feeder is that it can continuously deliver packaged electronic components to the SMT machine, such as resistors, capacitors, IC chips and other SMD components. The efficient operation of the continuous feeder is an important part of the automation, high speed and mass production of the SMT production line. By optimizing the feeding process, production efficiency and product quality can be greatly improved

After correct identification, driving motor 2 is started to drive the discharge shaft to rotate and discharge the electronic components onto the component suction tray for the placement machine to pick up the components, thereby achieving the effect of conveying different types of electronic components in conjunction with the placement machine. This solves the problem in the prior art that the placement machine feeder can only convey one tray and does not have universality. The feeder needs to be replaced according to different components, which reduces the production efficiency of the placement machine. The feed tray of the feeder can be improved so that it can alternately convey different types of electronic components, thereby reducing the number of shutdowns to replace the feed tray and achieving the purpose of improving production efficiency.

The identification and unloading component 3 includes an image recognition device 31 arranged above the feeding tray 22. The upper surface of the comprehensive rotating disk 21 is fixedly mounted with a feeding tray mounting frame 211 by bolts, and the lower surface of the feeding tray 22 is fixedly connected to the upper surface of the feeding tray mounting frame 211. The side wall of the feeding tray 22 is provided with a discharge groove, and the middle part of the feeding tray 22 is rotatably mounted with a discharge groove. The bottom end of the discharging shaft 23 passes through the feeding plate 22, and a magnet block 231 is fixedly installed on the inner wall of the integrated rotating plate 21. The outer surface of the discharging shaft 23 is evenly distributed with a discharging partition baffle 232. One end of the discharging partition baffle 232 is fixedly connected to the outer surface of the discharging shaft 23, and the other end of the discharging partition baffle 232 contacts the inner surface of the feeding plate 22. Extrusion springs 2322 are fixedly installed on both sides of the discharging partition baffle 232, and an elastic protective plate is fixedly installed on one end of the extrusion spring 2322. 2321, the image recognition device 31 is fixedly installed in front of the outer wall of the line installation column 12, the middle part of the front feeding zone bracket 13 is fixedly installed with a second driving motor 32, the output shaft of the second driving motor 32 is fixedly installed with a rotating shaft 321, the upper surface of the rotating shaft 321 is fixedly installed with a second magnet block 322, the magnetism of the second magnet block 322 is different from the magnetism of the first magnet block 231, the front end of the front feeding zone bracket 13 is fixedly installed with a component suction plate 33, and the rear side of the component suction plate 33 is provided with an arc-shaped connection groove adapted to the discharge groove of the feeding plate 22;

[0036] In the present embodiment, the SMT feeder is equipped with a SMT feeder controller, an external power supply device module of the SMT controller, a program control module and a signal connection transmission module are arranged in the SMT controller, the signal connection transmission module is used to connect the control terminal and the drive motor 232 for signal transmission, the program control module is used to receive control instructions and convert them into electrical signals and then output them to various drive components of the SMT feeder to control the SMT feeder to cooperate with the SMT machine to feed materials, the program control module includes a processor, a signal receiving unit, a signal converter and a signal output unit, the feed tray 22 is symmetrically and evenly fixed on the integrated rotating disk 21 through the feed tray mounting frame 211, different types of electronic components can be placed inside the feed tray 22, the discharge shaft 23 and the discharge partition baffle 232 separate the space inside the feed tray 22 so that the electronic components will not touch each other and be damaged, and at the same time ensure that only a single electronic component is discharged each time the discharge shaft 23 rotates, and the image recognition device 31 is used to identify whether the type of electronic component inside the feed tray 22 is Correct. After the identification is correct, the driving motor 2 32 receives the signal to drive the shaft 321 and the magnet block 2 322 to rotate a certain angle.

The elastic protective plate 2321 on the outer side of the discharge partition baffle 232 cooperates with the extrusion spring 2322 to not only protect and fix the electronic components, but also squeeze the electronic components from both sides when the discharge shaft 23 rotates to move the electronic components to the discharge port of the feeding tray 22 so that they are discharged to the component suction tray 33. This solves the problem that the feeder of the placement machine in the prior art can only convey one tray and does not have universality. The feeder needs to be replaced according to different components, which reduces the production efficiency of the placement machine. The feeding tray of the feeder can be improved so that it can alternately convey different types of electronic components, thereby reducing the number of shutdowns to replace the feeding tray and achieving the purpose of improving production efficiency.

[0037] Embodiment 2

[0038] See also Figures 1 to 9 On the basis of the first embodiment, in order to prevent the electronic components from being squeezed and discharged by the elastic protective plate 2321 onto the component suction tray 33 and being damaged by collision, the present embodiment further proposes that a U-shaped buffer pad is laid on the upper inner wall of the component suction tray 33, and a buffer elastic ball is added between the U-shaped buffer pad and the inside of the component suction tray 33;

[0039] In this embodiment, when the discharge shaft 23 of the electronic component rotates to the discharge port at the front end of the feed tray 22, the elastic protective plate 2321 discharges the electronic component to the component suction tray 33 when the extrusion spring 2322 is elastically squeezed. The U-shaped buffer pad surrounds and buffers the electronic component. The buffer elastic ball can relieve the force of the collision so that the electronic component will not collide with the inner wall of the component suction tray 33 and cause damage. This further solves the problem in the prior art that the feeder of the placement machine can only convey one tray and is not universal. The feeder needs to be replaced according to different components, which reduces the production efficiency of the placement machine. The feed tray of the feeder can be improved so that it can alternately convey different types of electronic components, thereby reducing the number of shutdowns to replace the feed tray and achieving the purpose of improving production efficiency.

[0040] Embodiment 3

[0041] See also Figures 1 to 9 On the basis of the second embodiment, in order to realize the rotation of the integrated rotating disk 21 to replace the type of electronic components, this embodiment further proposes that an inner gear ring 212 is fixedly installed on the lower surface of the integrated rotating disk 21, a driving motor 24 is fixedly installed on one side of the lower surface of the feeder frame 1 for the placement machine, and a driving gear 241 is fixedly installed on the output shaft of the driving motor 24, and the outer surface of the driving gear 241 is meshed with the inner surface of the inner gear ring 212;

The feeder needs to be replaced according to different components, which reduces the production efficiency of the SMT machine. The feed tray of the feeder can be improved so that it can alternately transport different types of electronic components, thereby reducing the number of shutdowns to replace the feed tray and achieving the purpose of improving production efficiency.

[0043] Embodiment 4

[0044] See also Figures 1 to 9On the basis of the third embodiment, in order to facilitate the loading of the inside of the feeding tray 22, the present embodiment further proposes that a material unloading guide plate 221 is fixedly installed on the upper end of the feeding tray 22, and a material guide groove is opened on the inner side of the material unloading guide plate 221, and the material unloading guide plate 221 is a transparent acrylic plate. The loading assembly 4 includes a telescopic rod 41 fixedly installed inside the loading rack 11, and a rotating seat 42 is arranged above the loading rack 11. The output end of the telescopic rod 41 passes through the inner wall of the loading rack 11 and is fixedly connected to the lower surface of the rotating seat 42. A motor three 421 is fixedly installed on the top of the inner wall of the rotating seat 42. A vacuum negative pressure suction cup 43 is rotatably installed on the upper surface of the rotating seat 42 through a bracket. The bottom rotating shaft of the bracket of the vacuum negative pressure suction cup 43 passes through the inner wall of the rotating seat 42 and is fixedly connected to the output shaft of the motor three 421. The adsorption hole area of ​​the vacuum negative pressure suction cup 43 is adapted to the material guide hole of the unloading guide plate 221.

[0045] In this embodiment, different types of electronic components can be placed on the loading rack 11 in different areas. The telescopic rod 41 can control the telescopic rod 41 to move up and down to control the height of the vacuum negative pressure suction cup 43 to facilitate the absorption and release of electronic components. The vacuum negative pressure suction cup 43 absorbs and releases electronic components using the vacuum adsorption principle. The adsorption hole of the vacuum negative pressure suction cup 43 is designed to conform to the pouring groove of the unloading guide plate 221. The motor 421 controls the vacuum negative pressure suction cup 43 to rotate and absorb specific electronic components and then rotate to the top of the unloading guide plate 221. The retracting rod 41 causes the rotating seat 42 to descend, so that the vacuum negative pressure suction cup 43 fits the unloading guide plate 221 and releases it to complete the replenishment of the electronic components inside the feeding tray 22, so that the feeding tray 22 is automatically loaded, further solving the problem in the prior art that the feeder of the placement machine can only convey one tray and has no universality and needs to replace the feeder according to different components, resulting in reduced production efficiency of the placement machine. The feeder tray of the feeder can be improved so that it can alternately convey different types of electronic components, thereby reducing the number of shutdowns to replace the feeder tray and achieving the purpose of improving production efficiency.

[0046] Embodiment 5

[0047] See also Figures 1 to 9 On the basis of the fourth embodiment, in order to realize that the elastic protective plate 2321 can be automatically separated during loading to facilitate the loading and placement of electronic components, this embodiment further proposes that a telescopic spring column is added to the middle of the top of the unloading guide plate 221, and a partition vertical plate adapted to the position of the elastic protective plate 2321 is arranged on the outer side of the upper end of the telescopic spring column, and the partition vertical plate is wide at the upper end and narrow at the lower end and is located in the middle of the elastic protective plate 2321;

[0048] In this embodiment, when the telescopic rod 41 causes the rotating seat 42 to descend so that the middle part of the vacuum negative pressure suction cup 43 is in contact with the unloading guide plate 221, the telescopic spring column will be squeezed and pressed down. At this time, the partition vertical plate will be inserted between the elastic protective plates 2321, and the elastic protective plates 2321 will be naturally separated so that the electronic components released by the vacuum negative pressure suction cup 43 fall into between the elastic protective plates 2321 and are fixed by the elastic protective plates 2321, further solving the problem in the prior art that the feeder of the placement machine can only convey one tray and has no versatility. The feeder needs to be replaced according to different components, which reduces the production efficiency of the placement machine. The feeding tray of the feeder can be improved so that it can alternately convey different types of electronic components, thereby reducing the number of shutdowns to replace the feeding tray and achieving the purpose of improving production efficiency.

[0049] Embodiment 6

[0050] See also Figures 1 to 9 Based on the fifth embodiment, this embodiment further proposes a method for using a continuous feeding mechanism for a placement machine, comprising the following steps:

[0051] Step 1: Convey electronic components. The driving motor 1 24 receives a signal from the controller and starts to rotate, driving the integrated rotating disk 21 to rotate, and the feeding tray 22 where the electronic components required by the placement machine are located is delivered to the rear end of the component suction tray 33;

[0052] Step 2: Identify and proofread the electronic components and discharge them. The image recognition device 31 performs image recognition and proofreading on the electronic components on the lower feeding tray 22. If the image recognition and proofreading is correct, the drive motor 2 32 receives the controller signal to start working and drives the discharge shaft 23 to rotate and discharge the electronic components inside the feeding tray 22 to the component suction tray 33, waiting for the placement machine to suck them.

[0053] Step three: replenishing the material. After the electronic components on the feeding tray 22 are completely discharged, the image counter carried by the image recognition device 31 transmits a signal to the controller, and the telescopic rod 41, the motor three 421 and the vacuum negative pressure suction cup 43 receive the controller signal. The telescopic rod 41 first lowers the rotating seat 42. After the vacuum negative pressure suction cup 43 works to absorb the same electronic components stored in a specific area on the loading rack 11, the telescopic rod 41 is lifted, and the motor three 421 rotates the vacuum negative pressure suction cup 43 to a certain angle to vertically overlap with the unloading guide plate 221. The telescopic rod 41 lowers the rotating seat 42 again to make the vacuum negative pressure suction cup 43 fit with the unloading guide plate 221. The vacuum negative pressure suction cup 43 releases the absorbed electronic components, so that the electronic components are replenished in the feeding tray 22.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

According to the continuous feeding mechanism for a chip mounter according to any one of claims 1 to 7, a method for using the continuous feeding mechanism for a chip mounter is provided, characterized in that: The following steps are involved: Step 1: electronic components are transported, and the driving motor 1 (24) receives a signal from the controller and starts to rotate, driving the integrated rotating disk (21) to rotate, and the feeding disk (22) where the electronic components required by the placement machine are located is sent to the right side of the component suction disk (33); Step 2: Identify, proofread and discharge electronic components. The image recognition device (31) performs image recognition and proofreading on the electronic components on the lower feeding tray (22). If the image recognition and proofreading is correct, the second drive motor (32) receives a signal from the controller and starts to drive the discharge shaft (23) to rotate and discharge the electronic components inside the feeding tray (22) onto the component suction tray (33) to wait for the placement machine to suck them. Step 3: Replenishing the material. After the electronic components on the feeding tray (22) are completely discharged, the image counter carried by the image recognition device (31) transmits a signal to the controller. The telescopic rod (41), the motor three (421) and the vacuum negative pressure suction cup (43) receive the controller signal. The telescopic rod (41) first causes the rotating seat (42) to descend. After the vacuum negative pressure suction cup (43) works to absorb the same electronic components stored in a specific area on the feeding rack (11), the telescopic rod (41) is lifted. The motor three (421) causes the vacuum negative pressure suction cup (43) to rotate a certain angle to vertically overlap with the unloading guide plate (221). The telescopic rod (41) causes the rotating seat (42) to descend again to make the vacuum negative pressure suction cup (43) fit with the unloading guide plate (221). The vacuum negative pressure suction cup (43) releases the absorbed electronic components, so that the electronic components are replenished in the feeding tray (22).
