Description

Technical Field

[0001] This application relates to the technical field of integrated chip processing, and in particular to an automatic feeding device for a gravity-type test and sorting machine. Background Technology

[0002] Integrated chips are electronic components assembled from pre-manufactured chips using semiconductor technology. These chips can contain various functional units such as processors, memory, and graphics processors. This technology is widely used in fiber-to-the-home, ultra-long-distance intercity networks, and industrial automation control, promoting the implementation of "copper out of the home and fiber-to-the-home".

[0003] Integrated chips must undergo rigorous testing before leaving the factory. These tests cover various performance parameters, such as current and voltage. Chips that fail to meet the test requirements are then screened out, and those with different test results are categorized.

[0004] Currently, gravity-type testing and sorting machines are generally used to replace manual sorting. After multiple integrated chips are loaded into the material tube, the material tube is manually sent to the top of the equipment. The equipment will control the material tube to tilt downwards, so that multiple integrated chips inside the material tube leave the material tube in sequence under the action of gravity and move along a predetermined route to complete the test. The sorting is completed based on the test results.

[0005] However, the feeding process of the existing gravity-type test and sorting machine is complicated and inconvenient, and requires a lot of time and effort from the staff. Summary of the Invention

[0006] This application provides an automatic feeding device for a gravity-type testing and sorting machine, which can effectively and conveniently simplify the feeding operation of the material tube for workers, thereby effectively reducing the burden on workers.

[0007] This application provides an automatic feeding device for a gravity-type testing and sorting machine, which adopts the following technical solution: An automatic feeding device for a gravity-type testing and sorting machine includes a material platform, a material storage component, a first feeding component, a second feeding component, and a third feeding component; The material platform is located on one side of the machine body. The material storage component and the first feeding component are both located on the material platform, and the second feeding component and the third feeding component are both located on the machine body. The material storage assembly is inclined and includes two frames, multiple lifting platforms, and multiple positioning structures. A storage space is formed between the two frames, in which multiple feeding pipes are placed at an incline. The feeding pipes store material with their outlet ends tilted upwards, and the multiple feeding pipes are stacked in the storage space. The lifting platform is located at the bottom of the storage space and is used to control the lifting and lowering of the feeding pipes along the storage space. The multiple positioning structures are respectively located at the bottom of the two frames and are used to position the feeding pipes located at the bottom, so that a feeding channel is formed below the feeding pipes located at the bottom. The first feeding assembly includes a first feeding rack and a first driving member; the first feeding rack is slidably disposed on the top of the material platform and slides along the feeding channel, and the first driving member is used to drive the first feeding rack to slide. The second feeding assembly includes a second feeding rack and a second driving member; the second feeding rack is slidably disposed on one side of the top of the machine body, and its sliding direction is perpendicular to the sliding direction of the first feeding rack, and the second driving member is used to drive the second feeding rack to slide. The third feeding assembly includes a third feeding rack and a third driving component; the third feeding rack is slidably disposed on the top of the machine body, and its sliding direction is parallel to the sliding direction of the first feeding rack, and the third driving component is used to drive the third feeding rack to slide; The feed tube is kept in a stored state for feeding, and the top of the machine body is provided with a structure for flipping the feed tube to tilt the integrated chip.

[0008] By adopting the above technical solution, the operation is convenient for staff. After stacking multiple tubes filled with integrated chips in the storage space, the lifting platform, positioning structure, and first feeding component work together to allow the tube at the bottom to fall onto the first feeding rack. Then, the first feeding component, the second feeding component, and the third feeding component feed the tubes in sequence, finally placing the tubes in the correct position to await the tilting of the integrated chips. The tubes are stored and fed in an inclined position, which effectively reduces the probability of integrated chips falling from the outlet end of the tubes, improving the reliability and stability of the feeding. Furthermore, the increased automation of the feeding effectively simplifies and facilitates the feeding operation for staff, thereby effectively reducing the burden on them.

[0009] Optionally, the lifting platform has limitations in the process of driving the material pipe to rise and fall; When the lifting platform drives the material tube to rise to its limit position, the material tube is precisely positioned by the positioning structure; when the lifting platform drives the material tube to fall to its limit position, the material tube is precisely fed by the first feeding rack.

[0010] By adopting the above technical solution, the lifting platform and the positioning structure can be easily coordinated to allow the material tube at the bottom to fall onto the first loading rack. At the same time, when the material tube at the bottom falls onto the first loading rack, the positioning structure can easily position the new material tube.

[0011] Optionally, one side of the third feeding rack has a pusher plate, and the pusher plate pushes away from the previous feeding tube during the process of the third feeding rack sliding to position the feeding tube.

[0012] By adopting the above technical solution, the third feeding component can simultaneously push away the previous feeding tube during the feeding process, thereby effectively improving the feeding efficiency of the feeding tube and saving the operator the need to manually replace the feeding tube.

[0013] Optionally, the top of the machine body away from the second feeding assembly has a recycling hopper for recycling the material tube, and the material tube enters the recycling hopper after being pushed away by the pusher plate.

[0014] By adopting the above technical solution, the material tube pushed away by the pusher plate can be easily recovered, making it convenient to refill the integrated chip for use in the future.

[0015] Optionally, the material platform has a storage space inside for temporary storage of multiple material tubes, and the storage space forms an opening on the side of the material platform away from the machine body.

[0016] By adopting the above technical solution, it is convenient for staff to temporarily store multiple tubes filled with integrated chips in the storage space, so that staff can replenish the tubes in the storage space as needed.

[0017] Optionally, the outlet end of the material tube is detachably provided with a cap, and the material tube is temporarily stored in the storage space with the cap installed and in a storage position.

[0018] By adopting the above technical solution, it is possible for staff to temporarily store the tubes filled with integrated chips, thereby effectively reducing the probability of integrated chips falling out of the tubes due to operational errors during the process of placing the temporarily stored tubes into the storage space.

[0019] Optionally, the cap is locked to the material tube by a locking structure. When the positioning structure positions the material tube, the locking structure is unlocked, and the cap and the material tube can be separated after the locking structure is unlocked.

[0020] By adopting the above technical solution, the cap and the feed tube can be easily separated when the feed tube is in the state of waiting for the first feeding component to feed, thereby effectively improving the continuity of feed tube feeding.

[0021] Optionally, the top of the material platform is provided with multiple recycling channels for recycling the cap; The two ends of the recycling channel are respectively connected to the storage space and the material storage space, and the cover enters the recycling channel under the action of gravity after separating from the material pipe.

[0022] By adopting the above technical solution, when the feed tube and the cap are separated and feeding begins, the separated cap will enter the storage space along the recycling channel, which makes it convenient for the staff to use the cap to seal the outlet end of the feed tube when the feed tube filled with integrated chips is placed into the storage space for temporary storage.

[0023] Optionally, the end of the recycling channel near the storage space has a guide surface for guiding the cap in the recycling channel into the storage space, and the guide surface is near the bottom of the storage space.

[0024] By adopting the above technical solution, the guide surface can be easily sealed and enter the storage space along the recycling channel and then leave the recycling channel, thereby further facilitating the staff to retrieve it.

[0025] Optionally, the two sides of the cover have a plurality of corresponding protrusions and a plurality of grooves, and the grooves are for the protrusions to be inserted into and fitted. The bottom of the storage space is provided with multiple positioning grooves for the protrusions to be inserted and engaged. After the material tube is positioned in the storage space through the positioning grooves, a space for the cap to be recycled is formed on the side of the material tube near the recycling channel. The protrusions contact the guide surface to facilitate the guide surface to guide the cap into the storage space. When multiple material tubes are temporarily stored in the storage space, the multiple material tubes are stacked stably by the insertion and engagement of the protrusions and grooves. The protrusions and grooves of the multiple material tubes stacked in the storage space maintain the insertion and engagement.

[0026] By adopting the above technical solution, multiple tubes can be stacked in the storage space and the material storage space, and the stability of stacking can be improved. At the same time, it can effectively remind the staff to place the tubes in the storage space and the material storage space in the correct position. In addition, it can further improve the stability of the cap entering the storage space under the action of the guide surface and reduce the probability of the cap entering the storage space colliding and being damaged by the tubes temporarily stored in the storage space.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. It can effectively and conveniently simplify the material loading operation for staff, thereby effectively reducing the burden on staff; 2. It can improve the stability of the feed tube and reduce the probability of integrated chips falling off during the feed tube process; 3. It can improve the continuity of the process of replacing the old material pipe with the new one, effectively improve the feeding efficiency, and save manual operation time. 4. It can improve the reliability of the integrated chip maintaining a stable position in the feed tube during the process from temporary storage to storage. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] Example 1: Reference Figure 1 and Figure 2This application discloses an automatic feeding device for a gravity-type testing and sorting machine, used to assist workers in feeding a tube 8 filled with integrated chips, so that the integrated chips in the tube 8 can be tilted out sequentially after the tube 8 is flipped to complete the testing and sorting. In this embodiment, the tube 8 is preferably strip-shaped, and one end of its length is detachably connected to a pin for limiting the integrated chips inside the tube 8, so that the two ends of the internal space of the tube 8 can form a positioning space. Since the gravity-type testing and sorting machine and the aforementioned tube 8 are both prior art in this field, they will not be described in detail here, and they are only briefly shown in the accompanying drawings (the pin of the tube 8 is omitted).

[0032] Reference Figure 2 and Figure 3 The feeding device is installed near the top of the machine body 1. The top of the machine body 1 has a structure for tilting the material tube 8 to pour the integrated chips, and the feeding device is used to feed the material tube 8 filled with multiple integrated chips to the structure.

[0033] The feeding device includes a material platform 2 for workers to prepare material tubes 8 filled with integrated chips in advance, a material storage component 3 for storing multiple material tubes 8 waiting to be fed, and a first feeding component 4, a second feeding component 5, and a third feeding component 6 for transporting material tubes 8 for feeding.

[0034] The material platform 2 has a rectangular parallelepiped structure and is fixedly installed on one side of the machine body 1 along its width direction, which is parallel to the width direction of the machine body 1. The storage component 3 is installed on the top of the material platform 2 and close to the top of the machine body 1. The interior of the material platform 2 has a storage space 21 for temporarily storing multiple material tubes 8 filled with integrated chips, which facilitates the movement of the material tubes 8 from the storage space 21 to the storage component 3 for storage as needed. In this embodiment, the installation height of the material platform 2 on the machine body 1 is preferably ergonomic, allowing the operator to stand on one side of the machine body 1 to temporarily store and transfer the material tubes 8.

[0035] The storage space 21 has an opening on the side of the material platform 2 away from the machine body 1 for the material supply tube 8 to enter. The inner wall of the bottom of the storage space 21 is inclined, which facilitates the temporary storage of the material tube 8 filled with integrated chips in the storage space 21 with its outlet end (i.e., the end away from the pin) tilted upward. In this embodiment, it is preferable that the inner wall of the bottom of the storage space 21 is inclined downward toward the test module of the gravity test sorting machine; and it is preferable that multiple material tubes 8 are neatly arranged and stacked in the storage space 21.

[0036] The storage assembly 3 includes two frames 31 for assisting in the stacking and storage of multiple material tubes 8, multiple lifting platforms 32 for controlling the lifting and adjusting position of the stored material tubes 8, and multiple positioning structures 33 for positioning the stored material tubes 8.

[0037] Two frames 31 are fixedly installed at both ends of the material platform 2 along its length. The top of the material platform 2 is an inclined surface, so that the frames 31 are installed at an inclination in the same direction on the material platform 2. A storage space 34 is formed between the two frames 31, where multiple feed pipes 8 are stacked and stored at an inclination. In this embodiment, it is preferable that two storage spaces 34 are formed between the two frames 31. The two storage spaces 34 are distributed along the width direction of the material platform 2. The feed pipes 8 are stacked and stored in the storage spaces 34 with their outlet ends tilted upwards towards the test module of the near-gravity test sorting machine. The feed pipes 8 are inserted from the top opening of the storage space 34, and the feed pipes 8 in the storage space 34 can only move along the inclination direction of the storage space 34. It is also preferable that the frames 31 can be adapted to different sizes of feed pipes 8 by changing different limiting structures.

[0038] The lifting platform 32 is installed on the top of the material platform 2 and is distributed at both ends of the bottom of the storage space 34. It contacts the end of the material pipe 8 located at the bottom of the storage space 34 and is used to drive the material pipe 8 to move up and down along the inclined direction of the storage space 34. In this embodiment, the lifting platform 32 is preferably a platform controlled by a servo cylinder; and preferably, the storage assembly 3 includes four lifting platforms 32, which are distributed in pairs at the bottom of the two storage spaces 34. The two lifting platforms 32 located in the same storage space 34 operate synchronously and are used to adjust the lifting of the same material pipe 8. Since the lifting platform 32 with the above functions is common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0039] The lifting platform 32 has limitations in controlling the lifting and lowering of the material pipe 8. When the lifting platform 32 drives the material pipe 8 in contact with it to rise to its limit position, a feeding channel 35 is formed below the bottom material pipe 8, through which the feeding pipe 8 passes along the width direction of the platform 2, and the feeding channel 35 communicates with the two storage spaces 34; when the lifting platform 32 drives the material pipe 8 in contact with it to descend to its limit position, the material pipe 8 is located in the storage space 34 waiting to be moved for feeding. In this embodiment, it is preferable that during the process of the lifting platform 32 driving the material pipe 8 in contact with it from rising to its limit position to descending to its limit position, the material pipe 8 is displaced by a distance equal to the length of one material pipe 8 body.

[0040] Multiple positioning structures 33 are respectively installed on two frames 31, and are used to position the material tubes 8 located at the bottom in the two storage spaces 34. In this embodiment, the preferred positioning structure 33 is an insert rod controlled by a servo cylinder. The insert rod is adapted to the internal space of the material tube 8, and after being inserted into the end of the material tube 8, it positions the material tube 8 in the storage space 34. Preferably, the storage assembly 3 includes a total of four positioning structures 33, which are distributed in pairs on the two frames 31. The corresponding two positioning structures 33 installed on different frames 31 operate synchronously and are used to position the same material tube 8. Since the positioning structure 33 with the above functions is a common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0041] When the lifting platform 32 drives the material pipe 8 in contact with it to rise to the limit position, the material pipe 8 is exactly in the position where the positioning structure 33 positions it; when the lifting platform 32 drives the material pipe 8 in contact with it to fall to the limit position, the material pipe 8 above the material pipe 8 is exactly in the position where the positioning structure 33 positions it.

[0042] The first feeding assembly 4 is installed on the top of the material platform 2 and is used to drive the material tube 8 located in the feeding channel 35 to move along the width direction of the material platform 2 towards the machine body 1 for feeding. It includes a first feeding frame 41 for supporting the material tube 8 and carrying the material tube 8 to move for feeding, and a first driving member 42 for driving the first feeding frame 41 to move.

[0043] The first feeding rack 41 is slidably connected to the material platform 2 along the width direction of the material platform 2. Its top has a structure for placing the feeding pipe 8, and during its sliding towards the machine body 1, the feeding pipe 8 on the first feeding rack 41 can maintain a stable relative position. The first driving member 42 is located at the bottom of the feeding channel 35, and during the sliding of the first feeding rack 41 relative to the material platform 2, the first feeding rack 41 can pass through the bottom of the two storage spaces 34. In this embodiment, the first driving member 42 is preferably a conveyor belt structure driven by a servo motor, which facilitates the first driving member 42 to drive the first feeding rack 41 to slide back and forth; and preferably, the first feeding rack 41 prioritizes feeding multiple feeding pipes 8 located in the storage spaces 34 near the machine body 1. Since the above-mentioned first driving member 42 is common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0044] When the first feeding rack 41 slides to the bottom of the storage space 34, the corresponding two positioning structures 33 release the positioning of the bottom material tube 8, and the corresponding two lifting platforms 32 drive the material tube 8 to descend to the limit position. The material tube 8 will fall onto the first feeding rack 41 and wait for the first driving component 42 to drive the first feeding rack 41 to slide and drive the material tube 8 to move and feed.

[0045] The second feeding assembly 5 is installed on the top of the machine body 1 near the material platform 2 and above the material platform 2. It is used to drive the material tube 8, which is transported and fed by the first feeding assembly 4, to move along the height direction (vertical direction) of the machine body 1 towards the top of the machine body 1. It includes a second feeding frame 51 for supporting the material tube 8 and carrying the material tube 8 to move and feed, and a second driving member 52 for driving the second feeding frame 51 to move.

[0046] The second feeding rack 51 is slidably connected to the machine body 1 along the height direction of the machine body 1. Its top also has a structure for placing the feeding pipe 8. During its sliding towards the top of the machine body 1, the feeding pipe 8 on the second feeding rack 51 maintains a stable relative position. The second driving component 52 is installed on one side of the top of the machine body 1. During the sliding of the second feeding rack 51 relative to the machine body 1, the second feeding rack 51 remains in the space between the frame 31 and the machine body 1. In this embodiment, it is preferable that the second driving component 52 is also a conveyor belt structure driven by a servo motor, which facilitates the second driving component 52 driving the second feeding rack 51 to slide back and forth. Preferably, when the first feeding rack 41 slides towards the machine body 1 to its limit position, the feeding pipe 8 on the first feeding rack 41 will also be located above the second feeding rack 51 sliding downwards to its limit position, facilitating subsequent feeding of the feeding pipe 8 by the second feeding assembly 5.

[0047] The third feeding assembly 6 is installed on the top of the body 1 and is used to drive the material tube 8, which is transported and fed by the second feeding assembly 5, to move along the width direction of the body 1 towards the direction of the integrated chip tilting position on the top of the body 1. It includes a third feeding rack 61 for supporting the material tube 8 and carrying the material tube 8 to move and feed, and a third driving member 62 for driving the third feeding rack 61 to move.

[0048] The third feeding rack 61 is slidably connected to the top of the machine body 1 along the width direction of the machine body 1. Its top also has a structure for placing the feeding tube 8. During its sliding towards the tilting position of the integrated chip, the feeding tube 8 on the third feeding rack 61 can maintain a stable relative position. The third driving component 62 is installed on the top of the machine body 1. During the sliding of the third feeding rack 61 relative to the machine body 1, the third feeding rack 61 remains on the top of the machine body 1. In this embodiment, the third driving component 62 is preferably a conveyor belt structure driven by a servo motor, which facilitates the third driving component 62 driving the third feeding rack 61 to slide back and forth. Preferably, when the second feeding rack 51 slides towards the top of the machine body 1 to its limit position, the feeding tube 8 on the second feeding rack 51 will be above the third feeding rack 61, which has slid towards the material platform 2 to its limit position, facilitating the subsequent transfer of the feeding tube 8 to the third feeding assembly 6 for continued feeding.

[0049] Furthermore, in order to further improve the efficiency of feeding the feed tube 8 and eliminate the need for staff to replace the feed tube 8 at the integrated chip tilting position (removing the old feed tube 8 after tilting the integrated chip), it is preferable that the third feed rack 61 has a pusher plate 611 on the side opposite to the feed table 2 for pushing away the old feed tube 8.

[0050] During the process of the third feeding rack 61 feeding the material tube 8, the pusher plate 611 will first contact the old material tube 8, so that the old material tube 8 can be pushed away to make room for the new material tube 8 to be tilted; then, during the process of the new material tube 8 tilting the integrated chip, the third feeding rack 61 can smoothly slide towards the material platform 2 so that the pusher plate 611 passes the integrated chip tilting position.

[0051] Furthermore, the top of the preferred machine body 1, away from the material platform 2, has a recycling hopper 7 for recycling old material tubes 8. As the third feeding rack 61 slides towards the limit position near the integrated chip tilting position, the pusher plate 611 pushes the old material tube 8 away until it enters the recycling hopper 7, making it convenient for the staff to remove the material tube 8 from the recycling hopper 7 and refill it with integrated chips for use.

[0052] The implementation principle of the automatic feeding device for a gravity-type testing and sorting machine in this application is as follows: After stacking and storing multiple tubes 8 filled with integrated chips in the storage space 34 on one side of the material platform 2, the staff temporarily stores the multiple tubes 8 filled with integrated chips in the storage space 21. Then, the gravity test and sorting machine is started. The storage component 3, the first feeding component 4, the second feeding component 5 and the third feeding component 6 will operate in coordination with the operation of the gravity test and sorting machine. During the feeding process of the feed tube 8, the positioning structure 33 first releases the positioning of the feed tube 8, and then the lifting platform 32 controls the feed tube 8 to descend and fall onto the first feeding rack 41. Then, the first driving member 42 drives the first feeding rack 41 to slide and move the feed tube 8 toward the second feeding assembly 5. Then, the feed tube 8 is transferred to the second feeding rack 51, and the second driving member 52 drives the second feeding rack 51 to slide and move the feed tube 8 toward the third feeding assembly 6. After that, the feed tube 8 is transferred to the third feeding rack 61, and the third driving member 62 drives the third feeding rack 61 to slide and move the feed tube 8 to the integrated chip tilting position. At the same time, the pusher plate 611 pushes the old feed tube 8 away and into the recycling hopper 7 for collection.

[0053] Example 2: Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the material platform 2 and the material storage component 3 are used together, and the material tube 8 is also equipped with a cap 9 for sealing its outlet end, which reduces the probability of the integrated chip inside the material tube 8 falling out during the feeding process.

[0054] The inclination direction and angle of the inner wall at the bottom of the storage space 21 are consistent with the storage state of the material pipe 8 in the storage space 34, so that the material pipe 8 temporarily stored in the storage space 21 is in the same position as the material pipe 8 stored in the storage space 34.

[0055] Reference Figure 5 and Figure 6 The cap 9 is detachably connected to the outlet end of the feed tube 8, and has a locking structure inside for locking with the feed tube 8. In this embodiment, the preferred locking structure is two claws that slide inward driven by springs. The cap 9 locks the end of the tube 8 by clamping it with the two claws. The side of the cap 9 away from the tube 8 has a slot for unlocking the locking structure, and the slot is adapted to the positioning structure 33. When the tube 8 with the cap 9 installed is stored in the storage space 34, the cap 9 can slide along the storage space 34. The corresponding positioning structure 33 will position the tube 8 at the bottom together with the corresponding lifting platform 32. When the positioning structure 33 adjacent to the cap 9 positions the cap 9, it will drive the locking structure to unlock the tube 8. At this time, the tube 8 is positioned in the storage space 34 by the positioning structure 33 away from the cap 9 and the two corresponding lifting platforms 32. Since the locking structure and positioning structure 33 with the above functions are common prior art, they will not be described in detail here. The locking structure is omitted in the figure and the positioning structure 33 is only briefly shown.

[0056] Reference Figure 4 and Figure 5 The top of the material platform 2 has two recycling channels 22 for recycling the caps 9, and the two recycling channels 22 correspond one-to-one with the two storage spaces 34. The top of the recycling channel 22 is connected to the corresponding storage space 34, and the caps 9 enter from the storage space 34 under their own gravity. The bottom of the recycling channel 22 is connected to the storage space 21, so that the caps 9 entering the recycling channel 22 can enter the storage space 21, which is convenient for the staff to take out and then seal the outlet end of the material tube 8 filled with integrated chips, and then temporarily store the material tube 8 in the storage space 21.

[0057] Reference Figure 5 and Figure 6 The bottom of the recycling channel 22 has a guide surface 221 for guiding the cap 9 into the storage space 21, and it is close to the bottom of the storage space 21. When multiple material tubes 8 are temporarily stored in the storage space 21, the side of them near the recycling channel 22 has space for the cap 9 to be recycled into the storage space 21, so as to avoid the cap 9 from contacting the temporarily stored material tubes 8 during the process of entering the storage space 21. In this embodiment, the guide surface 221 is preferably an arc surface.

[0058] Furthermore, preferably, the two sides of the cap 9 have a plurality of protrusions 91 and a plurality of grooves 92, with each protrusion 91 and groove 92 corresponding to the other. The protrusions 91 and grooves 92 are adapted to each other, and when adjacent material tubes 8 are stacked, the protrusions 91 and grooves 92 of adjacent caps 9 are directly inserted into each other. In this embodiment, preferably, the cap 9 has a total of one protrusion 91 and one groove 92.

[0059] The material platform 2 has multiple positioning grooves 211 on the inner wall of the bottom of the storage space 21 that are adapted to the protrusions 91, so that the staff can determine the temporary storage position of the material tube 8 with the cover 9 installed in the storage space 21. The protrusions 91 of the cover 9 corresponding to the material tube 8 at the bottom of the storage space 21 are inserted and matched with the positioning grooves 211. The remaining tubes are stacked on top through the direct insertion and matching of the protrusions 91 and grooves 92 of the cover 9. The stacked material tubes 8 have high stability.

[0060] The material tube 8 with a cap 9 installed at the outlet end is stored in the material storage space 34 with the cap 9 located at the inclined upper end of the material tube 8 and the protrusion 91 of the cap 9 facing downward. The stacked material tubes 8 are also connected by the protrusion 91 and groove 92 between adjacent caps 9 to improve their stacking stability.

[0061] When the cap 9 enters the recycling channel 22, under its own gravity, the protrusion 91 of the cap 9 will come into contact with the guide surface 221, which facilitates the guide surface 221 to guide the cap 9. In this embodiment, it is preferable that the end of the protrusion 91 has a spherical surface to reduce the friction between the protrusion 91 and the guide surface 221.

[0062] The implementation principle of the automatic feeding device for a gravity-type testing and sorting machine in this application is as follows: After the staff fills the integrated chip into the material tube 8 to a certain extent, the cap 9 can be used to seal the outlet end of the material tube 8, effectively preventing the integrated chip in the material tube 8 from falling out during the feeding process. After the integrated chip is loaded into the tube 8, the cap 9 is installed at the outlet end and then temporarily stored in the storage space 21. During the temporary storage of the tube 8, the protrusion 91 on the cap 9 is first inserted into the positioning groove 211 to make the tube 8 temporarily stored at the bottom of the storage space 21 have high positional stability, which makes it easier for the staff to stack the tube 8 in the storage space 21. At the same time, it can effectively improve the positional stability of multiple tubes 8 temporarily stored in the storage space 21 and reduce the probability of the stacked tubes 8 and the integrated chip falling due to vibration or unstable stacking operation. During the feeding process of the material tube 8 stored in the storage space 34, after the positioning structure 33 releases the positioning of the cover 9, the locking structure of the cover 9 releases the locking of the material tube 8. At this time, it can enter the recycling channel 22 under its own gravity. Then, the protrusion 91 on the cover 9 will contact the guide surface 221 and enter the storage space 21 under the guidance of the guide surface 221 for easy access by the staff.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
