[0044] The following is a preferred embodiment of an automatic feeding device for tube-packed electronic materials provided by the present invention that can solve the above technical problems.

[0045] Please refer to Figure 1 and Figure 2 ,in Figure 1 It is a schematic structural diagram of a preferred embodiment of the automatic feeding equipment for tube-packed electronic materials of the present invention. Figure 2 This is one of the partial structural schematic diagrams of the push rod feeding mechanism of the automatic feeding equipment for tube-packed electronic materials of the present invention.

[0046] In the figures, structurally similar elements are denoted by the same reference numerals.

[0047] The present embodiment provides an automatic feeding device for tube-packed electronic materials, which includes: a frame 11, a material tube distribution mechanism 12, an empty tube storage box 13, a push rod feeding mechanism 14, and a direct vibration feeding mechanism 15.

[0048] The material pipe dividing mechanism 12 and the empty pipe storage box 13 are connected to the frame 11, and the empty pipe storage box 13 is located below the material pipe dividing mechanism 12. The empty pipe storage box 13 is used to receive empty material pipes. A plurality of material pipes 16 are stacked on the material pipe dividing mechanism 12, and the push rod feeding mechanism 14 and the direct vibration feeding mechanism 15 are respectively arranged on both sides of the bottom end of the material pipe dividing mechanism 12.

[0049] Please refer to Figure 2 and Figure 3 , wherein the push rod feeding mechanism 14 includes a film winding box 149, a material pushing piece 1491, and a material pushing driving device. The material pushing piece 1491 is wound and arranged in the film winding box 149, and one end of the material pushing piece 1491 extends out of the film winding box 149. The material pushing driving device clamps the extended end of the material pushing piece 1491 to drive the material pushing piece 1491 to extend. The material pushing piece 1491 is used to push the electronic material in the material tube 16 at the bottom of the material tube branch mechanism 12 to the direct vibration feeding mechanism 15. Through the extension and feeding of the material pushing piece 1491, the electronic material 1C in the material tube 16 at the bottom of the material tube branch mechanism 12 can be pushed to the direct vibration feeding mechanism 15 stably and efficiently, and at the same time, the material pushing piece 1491 can be rolled up into the film winding box 149, so that the overall structure is compact and the volume is small.

[0050] In addition, the frame 11 in this embodiment is a frame-shaped structure, the material pipe distribution mechanism 12 is arranged on the top of the frame 11, and the empty pipe storage box 13 is arranged inside the inner frame of the frame 11. An electric control box 171 is arranged on the bottom surface of the inner frame of the frame 11. A power interface 172 for connecting the motor, various sensors and other components with electricity, an air source interface 173 for connecting the air source of components such as the cylinder, and an operation button assembly 174 are arranged on one side of the outside of the frame 11.

[0051] Please refer to Figure 2 and Figure 3 In this embodiment, the push drive device includes a fixing plate 141, an adjusting block 142, a motor 143, an active driving wheel 144, a driven driving wheel 145, a driving pulley 146, and a driven pulley 147.

[0052] The adjusting block 142 is slidably and adjustably arranged on the fixing plate 141 , and the sliding direction of the adjusting block 142 is perpendicular to the pushing piece 1491 .

[0053] The active driving wheel 144 is rotatably arranged on one side of the fixing plate 141, and the driven driving wheel 145 is rotatably arranged on one side of the adjusting block 142. The material pusher 1491 is clamped between the active driving wheel 144 and the driven driving wheel 145, so that the active driving wheel 144 and the driven driving wheel 145 can clamp the material pusher 1491 more stably through the sliding of the adjusting block 142.

[0054] The motor 143 is fixedly connected to the fixed plate 141, the driving pulley 146 is connected to the output end of the motor 143, the driven pulley 147 is fixedly connected to one end of the driving drive wheel 144, and the driving pulley 146 and the driven pulley 147 are connected by a belt 148, which facilitates the staggered arrangement of the two groups of motors 143, the driving drive wheel 144, and the driven drive wheel 145, making it more compact.

[0055] In this embodiment, the push drive device further includes a connecting plate 1411 , which is fixedly disposed on the top surface of the fixing plate 141 , and the motor 143 is connected to the connecting plate 1411 .

[0056] A slide groove is arranged on the fixed plate 141, and the slide groove passes through the top surface of the fixed plate 141. The adjusting block 142 is slidably arranged in the slide groove. A tensioning spring 1421 is arranged between the adjusting block 142 and the connecting plate 1411. The elastic force of the tensioning spring 1421 enables the driven driving wheel 145 to move toward the direction close to the active driving wheel 144. The driven driving wheel 145 and the active driving wheel 144 can stably clamp the pushing piece 1491 and push the pushing piece 1491 to extend and feed.

[0057] Please refer to Figure 4Among them, the push rod feeding mechanism 14 also includes a guide plate and a limit block 14C. The guide plate is fixedly connected to the fixed plate 141. The guide plate is located between the material pipe branch mechanism 12 and the film box 149. A guide groove 14D is arranged on the guide plate. The push piece 1491 is arranged through the guide groove 14D, so that the push piece 1491 can extend and feed in a stable direction. The push piece 1491 is not easy to bend and can move in a straight line more stably.

[0058] The end of the push piece 1491 away from the film box 149 is connected to the limit block 14C, and the cross-sectional dimension of the limit block 14C is larger than the cross-sectional dimension of the guide groove 14D. When the push piece 1491 retracts, the limit block 14C can contact the guide plate to form a limit, thereby preventing the push piece 1491 from retracting to a position where it cannot be clamped by the driven drive wheel 145 and the active drive wheel 144.

[0059] Please refer to Figure 5 and Figure 6 In this embodiment, the material pipe dividing mechanism 12 includes a pipe storage vertical plate 121, a bottom plate 122, a dividing cylinder 123, a supporting cylinder 124, and a supporting plate 126.

[0060] Two pipe storage plates 121 are arranged opposite to each other on the top of the frame 11, and a pipe storage groove 1211 for placing the material pipe 16 is provided on the side of the two pipe storage plates 121 close to each other. The two ends of the bottom material pipe 16 in the pipe storage groove 1211 are respectively connected to the push rod feeding mechanism 14 and the direct vibration feeding mechanism 15.

[0061] Please refer to Figure 6 , a branch cylinder 123 is arranged outside each pipe storage vertical plate 121, and the output end of the branch cylinder 123 extends into the pipe storage groove 1211, and the branch cylinder 123 is used to limit the material pipe 16 in the pipe storage groove 1211. Specifically, an L-shaped clamping block 1231 can be connected to the output end of the branch cylinder 123, and the clamping block 1231 is inserted into the port of the material pipe 16. The clamping block 1231 is arranged in an L shape, which is more convenient for compact arrangement of the branch cylinder 123 and adjacent components, for example, the branch cylinder 123 can be arranged closer to the connecting plate 18.

[0062] The bottom plate 122 is connected to the bottom of the pipe storage vertical plate 121, and the bottom plate 122 is connected to the frame 11. The supporting cylinder 124 is arranged at the bottom of the bottom plate 122. The supporting plate 126 is connected to the output end of the supporting cylinder 124. The supporting cylinder 124 drives the supporting plate 126 to extend to the bottom of the pipe storage tank 1211 to support the material pipe 16.

[0063] In this embodiment, the push rod feeding mechanism 14 is arranged on a bottom plate 122 away from the direct vibration feeding mechanism 15, and the bottom plate 122 away from the direct vibration feeding mechanism 15 is slidably connected to the frame 11, and the sliding direction of the bottom plate 122 is consistent with the length direction of the material tube 16 in the storage tube slot 1211. In this way, by moving and adjusting the position of the bottom plate 122, the distance between the two storage tube vertical plates 121 can be adjusted, so as to be suitable for feeding material tubes 16 of different lengths.

[0064] It should be noted that the slidable and adjustable connection structure between the bottom plate 122 and the frame 11 can be a long groove provided on the bottom plate 122, and the screws pass through the long groove to connect with the frame 11. In addition, both of the two storage tube vertical plates 121 can be set to be slidably and adjustable with the frame 11, but the connection between the direct vibration feeding mechanism 15 and the frame 11 makes it difficult to move and adjust the bottom plate 122 close to the direct vibration feeding mechanism 15. Therefore, it is preferred that the bottom plate 122 far from the direct vibration feeding mechanism 15 is slidably and adjustable with the frame 11.

[0065] Please refer to Figure 6 Furthermore, the material pipe management mechanism 12 may also include a lifting cylinder 125, the lifting cylinder 125 is connected to the output end of the support cylinder 124, the support plate 126 is connected to the output end of the lifting cylinder 125, the extension direction of the output end of the support cylinder 124 is consistent with the length direction of the material pipe 16 in the storage pipe slot 1211, and the extension direction of the output end of the lifting cylinder 125 is consistent with the extension direction of the storage pipe slot 1211. In this way, the support plate 126 can move horizontally to avoid the material pipe 16 in the storage pipe slot 1211, and can also move vertically to extend into the storage pipe slot 1211 to support the material pipe 16. At the same time, the movement trajectory of the support plate 126 can form an avoidance with the connection plate 18.

[0066] Please refer to Figure 6 In this embodiment, the output end of the lifting cylinder 125 is connected to a connecting piece 1251 of an L-shaped structure, one end of the connecting piece 1251 is connected to the output end of the lifting cylinder 125, and the other end of the connecting piece 1251 is slidably connected to the side of the lifting cylinder 125. A long hole is provided on the support plate 126, and the extension direction of the long hole is consistent with the extension direction of the storage pipe groove 1211. A threaded hole corresponding to the long hole is provided on the side of the connecting piece 1251, and a screw passes through the long hole and is connected to the threaded hole, so that the support plate 126 and the connecting piece 1251 are fixedly connected and the connection position is adjustable. Through the adjustment of the support plate 126, the support plate 126 can support the material pipes 16 of different sizes at a position where they are precisely docked with the push rod feeding mechanism 14 and the direct vibration feeding mechanism 15.

[0067] In this embodiment, two tube storage grooves 1211 are arranged on the sides of the two tube storage vertical plates 121 close to each other, and the tube-loaded electronic material automatic feeding equipment includes two sets of push rod feeding mechanisms 14 corresponding to the two tube storage grooves 1211, and the active driving wheels 144 and the driven driving wheels 145 of the two push rod feeding mechanisms 14 are respectively arranged on the two sides of the same fixed plate 141, and the active belt pulleys 146 and the driven belt pulleys 147 corresponding to the two push rod feeding mechanisms 14 are also respectively arranged on the two sides of the same fixed plate 141. Two vibration conveying tracks 151 corresponding to the two tube storage grooves 1211 are arranged on the direct vibration feeding mechanism 15. In this way, the electronic materials 1C in the two material tubes 16 can be fed at the same time, with high work efficiency and low cost.

[0068] The straight vibration feeding mechanism 15 can be set at an angle, and the end of the straight vibration feeding mechanism 15 away from the material pipe branch mechanism 12 is lower. A positioning notch is set at the lower end of the vibration conveying track 151. The material pipe branch mechanism 12 can transport the material in the vibration conveying track 151 to the positioning notch at the lower end through vibration.

[0069] In this embodiment, a winding wheel is elastically rotatably arranged in the film box 149, similar to the winding structure of a tape measure, and the material pusher 1491 is wound around the outer periphery of the winding wheel to achieve stable return of the material pusher 1491.

[0070] Please refer to Figure 3 Optionally, a reset block 14A is slidably provided on the fixed plate 141, and the sliding trajectory of the reset block 14A is consistent with the elastic force direction of the tightening spring 1421. A pressure block 14B is provided on the side where the two adjustment blocks 142 are close to each other, and the pressure block 14B is located on the sliding trajectory of the reset block 14A.

[0071] When the driven driving wheel 145 contacts the material pushing piece 1491, the pressure block 14B and the reset block 14A are at a set distance, and the reset block 14A will not affect the contact between the driven driving wheel 145 and the material pushing piece 1491. However, due to the repeated extension and movement of the material pushing piece 1491, the initial position of the material pushing piece 1491 may gradually deviate from the active driving wheel 144, affecting the accuracy of the electronic material 1C pushed by the material pushing piece 1491. At this time, the reset block 14A can be driven to slide and squeeze the pressure block 14B, so that the adjustment block 142 moves away from the material pushing piece 1491, thereby making the driven driving wheel 145 and the active driving wheel 144 no longer clamp the material pushing piece 1491. Under the elastic contraction force of the winding wheel, the material pushing piece 1491 cooperates with the contact between the limit block 14C and the guide plate, and the material pushing piece 1491 returns to the initial position, eliminating the error formed during the long-term operation of the material pushing piece 1491.

[0072] Please refer to Figure 6 , Figure 7 as well as Figure 8 In this embodiment, the automatic feeding device for tube-packed electronic materials further includes a connecting plate 18, a limiting plate 19, a mounting block 1B and a reverse blocking rod 1A.

[0073] The connecting plate 18 is arranged between the material pipe management mechanism 12 and the direct vibration feeding mechanism 15, and is used to transfer the electronic material 1C on the material pipe management mechanism 12 to the direct vibration feeding mechanism 15. The top surface of the connecting plate 18 is provided with a transfer groove 181 for the electronic material 1C to slide. It should be noted that Figure 8 The transfer slot 181 indicated by the serial number 181 is used for directional transportation of the pin part of the electronic material 1C. The actual transfer slot 181 also includes the space between the connecting plate 18 and the limiting plate 19.

[0074] The limit plate 19 is connected to the top of the connecting plate 18. The limit plate 19 is used to prevent the electronic material 1C from escaping from the transfer slot. The mounting block 1B is connected to the storage tube vertical plate 121 of the material tube branch mechanism 12. The mounting block 1B is located above the limit plate 19. A avoidance groove is provided on the limit plate 19 corresponding to the transfer slot. The reverse baffle rod 1A is an L-shaped structure. One end of the reverse baffle rod 1A is rotatably connected to the mounting block 1B, and the other end of the reverse baffle rod 1A extends to the avoidance groove in the direction close to the straight vibration feeding mechanism 15. The rotation axis of the reverse baffle rod 1A is perpendicular to the extension direction of the transfer slot.

[0075] When the electronic material 1C moves toward the direction close to the direct vibration feeding mechanism 15, the reverse blocking rod 1A will be squeezed by the electronic material 1C and rotated in the direction away from the transfer slot 181, so that the reverse blocking rod 1A will not block the movement of the electronic material 1C. When the electronic material 1C moves in the direction away from the direct vibration feeding mechanism 15, the reverse blocking rod 1A will rotate in the direction close to the transfer slot 181, and the reverse blocking rod 1A can block the electronic material 1C from moving away from the direct vibration feeding mechanism 15, thereby preventing the electronic material 1C from flowing back in the opposite direction.

[0076] Please refer to Figure 1 In this embodiment, the empty tube storage box 13 is tilted, and an opening is provided at the lower end of the empty tube storage box 13, and a baffle 131 is provided at the opening. A slot is provided on the side plate of the empty tube storage box 13, and the baffle 131 is plugged into the slot on the side plate of the empty tube storage box 13, so that the baffle 131 can close the opening. When a certain number of empty material tubes 16 fall into the empty tube storage box 13, the baffle 131 can be opened to facilitate taking out the empty material tubes 16.

[0077] Optional, see Fig. 9 The connection structure between the baffle 231 and the empty tube storage box 13 can also be another implementation structure. The baffle 231 in this implementation structure has a different structure from the above-mentioned baffle 131, so different numbers are used to represent it.

[0078] Specifically, an extension strip 2311 is provided on one side of the baffle 231, and the extension direction of the extension strip 2311 is perpendicular to the plate surface of the baffle 231. The extension strip 2311 and the outer side surface of the empty tube storage box 13 are elastically slidably connected through a driving spring 232. The driving spring 232 is used to drive the baffle 231 to slide in a direction close to the opening, so that the baffle 231 closes the opening. When a certain number of empty tubes 16 fall into the empty tube storage box 13, by pulling the baffle 131 to slide in a direction away from the opening, the baffle 131 can continue to prevent the empty tubes 16 from sliding off, and the staff can conveniently take away the empty tubes 16 from the gap between the baffle 131 and the opening.

[0079] In addition, it should be noted that a connection block 233 connected to a driving spring 232 needs to be provided on the outer side of the empty tube storage box 13, and the driving spring 232 can be a tension spring. Two parallel long grooves can be provided on the extension strip 2311, and threaded holes are provided on the outer side of the empty tube storage box 13. Screws pass through the long grooves and are connected to the threaded holes, so that the baffle 131 and the storage box 13 can slide in a directional manner.

[0080] The working principle of the automatic feeding device for tube-loaded electronic materials of the present invention is as follows: a material sensor is provided on the direct vibration feeding mechanism 15. When the material sensor of the direct vibration feeding mechanism 15 senses that there is no material on the direct vibration feeding mechanism 15, the motor 143 of the push rod feeding mechanism 14 works, the active driving wheel 144 and the driven driving wheel 145 clamp the material pushing piece 1491 and extend it in the direction of the storage tube tank 1211, and push the electronic material 1C in the material tube 16 at the bottom of the storage tube tank 1211 to the direct vibration feeding mechanism 15, and the direct vibration feeding mechanism 15 transports the electronic material in an orderly manner to the positioning notch at the tail of the vibration conveying track 151. After the pushing is completed, the motor 143 is reversed to retract the material pushing piece 1491.

[0081] Then, the branch cylinders 123 at both ends control the clamping block 1231 to extend into the port of the second-to-last material tube 16 at the bottom of the storage tube slot 1211, thereby dragging the material tube 16 and the material tubes above it. After that, the support cylinders 124 and the lifting cylinders 125 at both ends retract, so that the support plate 126 no longer supports the material tubes, and the bottom empty material tube 16 in the storage tube slot 1211 falls into the empty tube storage box 13. After the empty material tubes 16 are discharged, the support cylinders 124 and the lifting cylinders 125 at both ends extend, the support plate 126 extends into the storage tube slot 1211, and the branch cylinders 123 at both ends retract, so that the stacked multiple material tubes 16 descend to be supported by the support plate 126. In this way, the next round of electronic materials can be pushed to the direct vibration feeding mechanism 15.

[0082] This completes the automatic feeding process of the automatic feeding equipment for tube-packed electronic materials in this preferred embodiment.

[0083] The automatic feeding equipment for tube-loaded electronic materials in this preferred embodiment can stably and efficiently push the electronic materials in a material tube at the bottom of the material tube branch mechanism to the direct vibration feeding mechanism through the pushing piece of the push rod feeding mechanism.

[0084] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
