Description

Technical Field

[0001] The present invention relates to the technical field of chip mounting, and in particular to a gas-driven chip recovery device. Background Art

[0002] In the lighting field, the application of LED (Light Emitting Diode) products is attracting worldwide attention. As a new green light source, LED is an inevitable trend in lighting technology development. The 21st century will be an era of new lighting sources represented by LED. Known as the fourth generation of lighting sources or green light sources, LEDs offer energy-saving, environmentally friendly, long lifespans, and compact size. They are widely used in various applications, including indicators, displays, decoration, backlighting, general lighting, and urban nightscapes.

[0003] The existing lamp bead panel needs to be glued and fixed after the chip is installed. However, in the technology, during the loading process of the lamp bead panel, the four contacts under the lamp beads need to face downward before they can be installed. If the four contacts face downward, testing and installation can be carried out. However, when feeding, only feeding can be carried out, and accurate screening cannot be performed. This makes it difficult to design an automatic feeding device for LED lamp beads with existing technology. The LED lamp beads are also the chips of LED lamps. hereinafter, chips are collectively referred to as LED lamp beads.

[0004] The existing published patent application: CN202411389067.9, a bulk LED feeding device, discloses a chip loading module but does not disclose how to screen the loaded chips to ensure that the four contacts of the chip face downward. Furthermore, even if it is possible to detect that the contacts are not facing downward, it is difficult to remove the corresponding chip from the conveyor track. Therefore, it is necessary to design a gas-driven chip recovery device that can automatically screen the chips and automatically discharge them after screening, ensuring that the chip contacts face downward, so that subsequent automatic installation and processing can be carried out.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example: The chip automatic feeding equipment includes a gas-driven chip recovery device and a bulk material feeding mechanism 11 for conveying chips to the gas-driven chip recovery device. A worker pours a large number of chips into the bulk material feeding mechanism 11, and then the chips are conveyed by the bulk material feeding mechanism 11 and finally enter the gas-driven chip recovery device. Figure 3 As shown, it specifically shows the specific structure of how the chip enters the gas-driven chip recovery device. The present invention provides a gas-driven chip recovery device, such as Figure 1-11As shown, it includes a support plate 1, a rotating disk 2 and a rotating mechanism for driving the rotating disk 2 to rotate. The support plate 1 and the rotating mechanism are fixedly installed on the workbench. The rotating mechanism includes a rotating shaft, which is fixedly connected to the rotating disk 2. Each rotating disk 2 is provided with a plurality of card slots 2a for the chips 10 to be inserted into. An outer ring 3 is fixedly provided on the support plate 1. The inner edge of the outer ring 3 fits with the outer edge of the rotating disk 2. A gasket 6 is fixedly provided on the inner edge of the outer ring 3. The top of the gasket 6 fits with the bottom of the rotating disk 2. The gasket 6 mainly plays a role of increasing the height, so that the subsequent chips can slide out better when they are discharged. The rotating disk 2 is wrapped by the outer ring 3. When the chip is inserted into the card slot 2a, as the rotating disk 2 rotates, the rotating disk 2 will be able to push multiple chips to slide along the circumferential direction. An avoidance gap 3a is provided on the outer ring 3, and the avoidance gap 3a is opposite to one of the card slots 2a, wherein a guide block 7 is fixedly provided on the support plate 1, and an insert block 7b is fixedly provided on the end of the guide block 7. A feed pipe 4 is provided directly below the avoidance gap 3a, and a feed gap is provided on the side of the feed pipe 4 close to the insert block 7b, and the insert block 7b is inserted into the feed gap. An inclined groove 7b1 is provided on the insert block 7b. When the chip 10 is pushed by the gas, the avoidance gap 3a avoids it, so that the chip 10 can slide horizontally and slide into the feed pipe 4 along the inclined groove 7b1, and enter the collection box through the material guide hose connected to the bottom of the feed pipe 4, and the bottom of the feed pipe 4 is connected to the material guide hose. The end of the detection tube 5 passes through the support plate 1 and the guide block 7 and is inserted into the gasket 6. The support plate 1 and the guide block 7 are provided with a square hole for the detection tube 5 to slide vertically. The gasket 6 is provided with an avoidance gap 6a for accommodating the end of the detection tube 5. A crossbeam 6b is fixedly provided on the gasket 6. The crossbeam 6b is located at the top of the avoidance gap 6a. The crossbeam 6b is used to prevent the bottom end of the chip 10 from being stuck in the avoidance gap 6a when the chip 10 slides horizontally. The top of the detection tube 5 is provided with a detection terminal 5 a. The detection terminal 5a is located in the avoidance gap 2 6a. The middle part of the detection tube 5 is a hollow structure for the connection wire of the detection terminal 5a to pass through. The bottom of the detection tube 5 is connected to the lifting mechanism, which is used to lift the detection tube 5 upward so that the detection terminal 5a contacts the contact at the bottom of the chip 10. When the detection tube 5 is lifted vertically upward, if the detection terminal 5a contacts the contact, a current signal will be generated, and the controller will not start the air blower, so that the chip 10 will not slide into the feed tube 4. If no current signal is generated, it means that the contact of the chip 10 is not at the bottom. At this time, the air blower will be used to blow air, and the chip 10 will be pushed into the feed tube 4.In order to enable the airflow to push the chip 10, the top of the air blow pipe 8 is fixedly connected to the bottom of the support plate 1, and the bottom of the air blow pipe 8 is connected to the air blower. The guide block 7 is provided with an air hole 7a, and the support plate 1 is provided with an air channel for the air blow pipe 8 to connect with the air hole 7a, so that the gas blown out along the air blow pipe 8 can enter the air hole 7a. The rotating disk 2 is provided with multiple air guide grooves 2b, and one side of the multiple air guide grooves 2b is respectively connected to multiple card slots 2a, wherein the bottom of any air guide groove 2b is connected to the air hole 7a. When the rotating disk 2 rotates, the multiple air guide grooves 2b will switch one by one to connect with the air hole 7a. When the chip 10 to be tested moves to the bottom of the test tube 5, if the terminal of the chip 10 is facing downward, the air blower will not blow air. If the terminal of the detection chip 10 is not facing downward, the blower will work, and the gas will enter the air hole 7a along the feed pipe 4, and then blow the side of the chip 10 through the air guide groove 2b, so that the chip 10 can be pushed along the card slot 2a, and finally the chip 10 will slide into the feed pipe 4.

[0033] To prevent the chip 10 from being pushed up, a pressure ring is fixed on the top of 03 to limit the top of the chip 10 and prevent it from being pushed up. The pressure ring has circular holes at multiple stations, and lenses are installed in the circular holes to facilitate the detection of the chip 10 through the lens by the sensor beam.

[0034] There is a gap between the edge of the chip 10 and the slot 2 a so that the chip 10 can slide more easily.

[0035] That is, through the above method, the detection tube 5 is pushed upward so that the detection terminal 5a can be tested for the orientation with the chip 10. If the terminal of the chip 10 is not facing downward, the blower is used to push the chip 10 sideways so that the chip 10 slides into the feed tube 4, realizing automatic discharge of the chip and ensuring that the chip contacts are facing downward, so that subsequent automatic installation processing can be carried out.

[0036] Since the air blower 8 needs to be in a normally closed state during the test, and needs to be in an open state when the test is unqualified, and the opening and closing speed needs to be fast, if the air blower needs to be started and stopped frequently, it takes a long time to start and stop, which is not conducive to the efficient operation of the equipment. Figure 12As shown, it also includes an airflow blocking mechanism 9, an electric push rod 13, a push column 14, a lifter 15 and a mounting bracket 19. The mounting bracket 19 is fixedly installed at the bottom of the support plate 1. The lifting mechanism is a lifter 15. The lifter 15 is located at the bottom of the detection tube 5 and is used to push the detection tube 5 upward. The lifter 15 is transmission-connected with the push column 14. The airflow blocking mechanism 9 is installed in the air blowing tube 8. The airflow blocking mechanism 9 is used to control the closing and opening of the air blowing tube 8, and the air blowing tube 8 is transmission-connected with the push column 14. The push column 14 can be horizontally slidably installed on the mounting bracket 19. The electric push rod 13 is fixedly connected to the mounting bracket 19, and the output end of the electric push rod 13 is fixedly connected to the push column 14. By controlling the electric push rod 13 to work, the electric push rod 13 can drive the push column 14 to slide horizontally to the left or right, so that the push column 14 can be controlled to drive the detection tube 5 and the air blowing tube 8 to work.

[0037] When the push pin 14 is pushed horizontally to the left to the final position on the left, the lifter 15 pushes the detection terminal 5a to contact the bottom of the chip 10, and the air blow pipe 8 is closed; at this time, the terminal position at the bottom of the chip 10 can be detected.

[0038] When the push pin 14 is pushed horizontally to the right to the final position on the right side, the lifter 15 drives the detection terminal 5a to separate from the bottom of the chip 10, and the air blower 8 opens; at this time, the gas blown out by the air blower enables the chip 10 to be blown and discharged along the feed pipe 4.

[0039] When the push pin 14 is pushed slightly to the right horizontally to the pre-test position, the lifter 15 drives the test terminal 5a to separate from the bottom of the chip 10, and the air blower 8 is closed. At this time, it is in the pre-test position. When switching to the test position, the distance that the retractor 16 needs to push is reduced, making the test faster. The air pressure in the pressure tank equipped with the air blower will not be reduced, and the air blower can be started without starting.

[0040] In order to enable the airflow blocking mechanism 9 to maintain two states in the case of three positions when the electric push rod 13 is pushed linearly, for this purpose, Figure 13 As shown, the airflow blocking mechanism 9 includes an expansion tube 9a fixedly connected to the push column 14 and a horizontal tube 9b integrally formed with the air blowing tube 8. The middle portion of the horizontal tube 9b is connected to the middle portion of the air blowing tube 8, and the expansion tube 9a is inserted into the horizontal tube 9b. The expansion tube 9a is provided with an air vent 9a1 that passes through the expansion tube 9a. When push pin 14 is pushed horizontally to the left to the final left position, vent 9a1 is located on the left side of the air tube 8 and is disconnected from the air tube 8. When push pin 14 is pushed horizontally to the right to the final right position, vent 9a1 is located in the middle of the air tube 8 and is connected to the air tube 8. When push pin 14 is pushed slightly to the right to the pre-detection position, vent 9a1 is located on the left side of the air tube 8 and is disconnected from the air tube 8. By controlling the movement of expansion tube 9a, whether vent 9a1 is connected to the air tube 8 can be controlled. A slight movement from the left to the right can change the position from the final left position to the pre-detection position. This slight movement allows vent 9a1 to be disconnected from the air tube 8, effectively achieving three positions while maintaining two states.

[0041] like Figure 13 As shown, the lifter 15 includes a positive trapezoidal block 15a and an inverted trapezoidal block 15b. The inverted trapezoidal block 15b is fixedly mounted on the bottom of the detection tube 5, and the positive trapezoidal block 15a is fixedly mounted on the end of the expansion tube 9a. The inclined surface of the inverted trapezoidal block 15b contacts the inclined surface of the positive trapezoidal block 15a. When the push column 14 is pushed horizontally to the right and slightly pushed to the pre-detection position, the top of the detection terminal 5a is located below the crossbeam 6b, which can separate the detection terminal 5a from the bottom of the chip 10. By pushing the push column 14 horizontally, the push column 14 pushes the positive trapezoidal block 15a to move. When the positive trapezoidal block 15a moves to the left, it can push the inverted trapezoidal block 15b upward, causing the detection terminal 5a to move upward and contact the bottom of the chip 10 for detection. When the positive trapezoidal block 15a moves to the right, the detection terminal 5a will move downward, separating the detection terminal 5a from the bottom of the chip 10.

[0042] Since the push column 14 is pulled to the right limit position when the air blowing pipe 8 is blowing, if the output end of the electric push rod 13 is not reset when the rotary disk 2 rotates again, this will cause the next chip 10 to be blown off. If the output end of the electric push rod 13 is waited for to reset, large-scale screening will take a long time. If the electric push rod 13 does not need to be reset, the air blowing pipe 8 can be closed. When the next chip 10 moves to the top of the detection tube 5, the electric push rod 13 is directly controlled to drive the push column 14 to the left limit position for detection, which can save a lot of time. Figure 12-14As shown, it also includes a limit clamping mechanism 17 and a push ring 18. The electric push rod 13 is fixedly connected to the push column 14 through the connecting plate 20 and the retractor 16. The connecting plate 20 is fixedly mounted on the push column 14. One end of the retractor 16 is fixedly connected to the connecting plate 20. The other end of the retractor 16 is fixedly connected to the output end of the electric push rod 13. The limit clamping mechanism 17 is fixedly mounted on the mounting bracket 19. The limit clamping mechanism 17 is used to limit the connection of the connecting plate 20. The right displacement end of the retractor 16 is fixedly provided with an unlocking lever 16a. When the push column 14 is pushed slightly to the right horizontally to the pre-test position, the working end of the limit clamping mechanism 17 contacts the connecting plate 20, and the unlocking rod 16a does not push the limit clamping mechanism 17 downward; at this time, the electric push rod 13 pushes the push column 14 to the left, and then switches to the final position on the left, so that the jack 15 lifts the detection terminal 5a upward, completing the detection process. When the push column 14 is pushed horizontally to the left, the unlocking rod 16a does not push the limit clamping mechanism 17 and the connecting plate 20 to unlock, and the retractor 16 is stretched; when the push column 14 is pushed horizontally to the left, the unlocking rod 16a does not push the limit clamping mechanism 17 and the connecting plate 20 to unlock, and the retractor 16 is pulled and retracted; The push ring 18 is fixedly mounted on the bottom of the turntable 2c. A plurality of protrusions 18a are provided on the push ring 18, and a groove 18b is provided between every two protrusions 18a. When the chip 10 is located above the detection tube 5, the end of the push pin 14 is facing the groove 18b, and when the push pin 14 is in the final position on the right, the end of the push pin 14 contacts the depression of the push ring 18. At this time, the airflow blocking mechanism 9 is in an open state, and the airflow can blow upward along the blow pipe 8, thereby blowing the chip 10 into the feed pipe 4. When the end of the push pin 14 contacts the protrusion 18a, the push pin 14 is in a pre-detection position; and when the rotating disk 2 drives the next chip 10 to move to the top of the detection tube 5, it will push the push pin 14 to slide horizontally, so that the airflow blocking mechanism 9 can close the blow pipe 8 to prevent the airflow from directly blowing the chip 10 off. While the push post 14 is being pushed, the retractor 16 will be stretched, allowing the connecting plate 20 to be displaced. Finally, the limit clamping mechanism 17 locks the connecting plate 20, making it impossible for the retractor 16 to be reset, thereby preventing the push post 14 from being reset while the rotating disk 2 continues to rotate.

[0043] When the electric push rod 13 pushes the next time, it can be pushed horizontally and quickly, so that the detection terminal 5a can directly detect the bottom of the chip 10. During this pushing process, the unlocking rod 16a will push the limit clamping mechanism 17 downward, and the retractor 16 will undergo a short contraction process, causing the airflow blocking mechanism 9 to open slightly. However, due to the high speed, the airflow has not yet filled the air cavity and has already closed, so it will not push the chip 10 to move. That is, through the above method, during the rotation of the rotating disk 2, if the electric push rod 13 does not push the push column 14 to close the airflow blocking mechanism 9, the airflow blocking mechanism 9 can also be automatically closed by the rotation of the rotating disk 2 to prevent the next chip 10 from being blown off.

[0044] like Figure 14 As shown, the limiting clamping mechanism 17 includes a clamping plate 17a, a triangular clamping block 17b, a lifting plate 17c, a lifting spring 17d, a limiting base plate 17e and two guide posts 17f. The guide posts 17f can be vertically slidably installed on the mounting frame 19. The lifting plate 17c is fixedly installed on the top of the two guide posts 17f, the limiting base plate 17e is fixedly installed on the bottom of the two guide posts 17f, the top of the lifting spring 17d is in contact with the lifting plate 17c, and the bottom of the lifting spring 17d is in contact with the mounting frame 19. The clamping plate 17a is fixedly installed on the lifting plate 17c, one side of the clamping plate 17a is in contact with the connecting plate 20, and the triangular clamping block 17b is fixedly installed on the lifting plate 17c. The triangular clamping block 17b is located at the bottom of the unlocking rod 16a. When the push column 14 is pushed horizontally to the right and slightly pushed to the pre-detection position, one side of the clamping plate 17a is in contact with the connecting plate 20, and one side of the triangular clamping block 17b is in contact with the unlocking rod 16a. When the electric push rod 13 pulls the unlocking lever 16a to the right, the unlocking lever 16a pushes the triangular clamping block 17b downward, causing the triangular clamping block 17b to move the lifting plate 17c upward, compressing the lifting spring 17d. At this time, the clamping plate 17a and the connecting plate 20 are unlocked, allowing the retractor 16 to pull the connecting plate 20. When the electric push rod 13 pulls the retractor 16 to the final right position, the end of the clamping plate 17a contacts the bottom of the connecting plate 20.

[0045] like Figure 15As shown, the retractor 16 includes a sleeve 16b, a retaining ring 16c, a push column 16d, a spring 16e, an extension column 16f and a circular plate 16h. One end of the push column 16d is fixedly connected to the connecting plate 20, and the other end of the push column 16d is inserted into the sleeve 16b. One end of the extension column 16f is fixedly connected to the push column 16d, and the other end of the extension column 16f is fixedly connected to the circular plate 16h. The retaining ring 16c is fixedly installed on the inner edge of the sleeve 16b, and the middle part of the extension column 16f is slidably connected to the retaining ring 16c. The spring 16e is sleeved on the outer edge of the extension column 16f, one end of the spring 16e is in contact with the retaining ring 16c, and the other end of the spring 16e is in contact with the circular plate 16h. The sleeve 16b is fixedly connected to the output end of the electric push rod 13. When the output end of the electric push rod 13 is retracted, the electric push rod 13 pulls the sleeve 16b to move. Since the connecting plate 20 is restricted, the push rod 16d cannot move, which causes the circular plate 16h to compress the spring 16e. After the connecting plate 20 is separated from it, the spring 16e pushes the circular plate 16h to contact the sleeve 16b, thus restoring the retractor 16 and preparing for the next stretching. The retaining ring 16c is screwed to the inner edge of the sleeve 16b.

[0046] During use, a worker pours a large number of chips into the bulk material feeding mechanism 11, which is then transported through the bulk material feeding mechanism 11 and finally enters the gas-driven chip recovery device. After the chip is inserted into the card slot 2a, as the rotary disk 2 rotates, the rotary disk 2 will be able to push multiple chips to slide along the circumferential direction. When the chip 10 to be tested moves to the top of the test tube 5, the push column 14 is pushed horizontally to the left to the final position on the left, and the lifter 15 pushes the test terminal 5a to contact the bottom of the chip 10, and the air blow tube 8 is closed. If a current signal is generated, indicating that the electric contact of the chip 10 is downward, the push column 14 is pushed slightly to the right to the pre-test position, and the lifter 15 drives the test terminal 5a to separate from the bottom of the chip 10, and the air blow tube 8 is still in a closed state.

[0047] If no current signal is generated, when the push pin 14 is pushed horizontally to the right to the final position on the right side, the lifter 15 drives the detection terminal 5a to separate from the bottom of the chip 10, and the air blow pipe 8 opens, allowing the chip 10 to be blown into the air flow. When pulled to the final position on the right side, the output end of the electric push rod 13 does not need to be reset. The turntable 2c drives the push ring 18 to rotate, so that the push ring 18 can automatically push the push pin 14 to the pre-detection position, preventing the next chip 10 from being directly blown off and shortening the working time of the equipment. In addition, after the push ring 18 pushes the push pin 14 to move, the push pin 14 can be self-locked to prevent the protrusion 18a from separating from the push pin 14, and the push pin 14 is reset to the final position on the right side.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
