[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0035] In the figure, units with similar structures are denoted by the same reference numerals.

[0036] Please refer to Figure 1 , a material tube feeding machine of the present invention is used to convey the material tube 9 of the chip tape to the testing device 8. The material tube feeding machine includes a frame 100, a feeding mechanism 3, a feeding mechanism 2 and a flipping and avoiding mechanism 1; the feeding mechanism 3, the feeding mechanism 2 and the flipping and avoiding mechanism 1 are all arranged on the frame 100. A support platform 11 is arranged on the frame 100.

[0037] The feeding mechanism 3 is used to convey the material tubes 9 to the support platform 11 one by one, and the end of the material tube is located at the flipping and avoiding mechanism 1; the flipping and avoiding mechanism 1 is located on the longitudinal side of the support platform 11, and is used to clamp the end of the material tube 9 and adjust the orientation of the material tube 9 so that the surface of the exposed chip of the material tube 9 faces upward; the feeding mechanism 2 is used to send the material tube 9 on the support platform to the testing device 8.

[0038] As Figure 2 , Figure 3 shown, the flipping and avoiding mechanism 1 includes a clamping assembly 12 and a flipping assembly 13. The support platform 11 has a support surface 110 for placing the material tube 9, and the feeding mechanism 3 is used to convey the material tubes 9 to the support surface 110 one by one. The material tube 9 is arranged along the longitudinal direction Y. The clamping assembly 12 is used to clamp the material tube 9, and the flipping assembly 13 can drive the clamping assembly 12 to rotate to change the orientation of the material tube 9. At the same time, the clamping assembly 12 and the material tube 9 can be avoided in the vertical direction Z so that the feeding mechanism 2 can clamp the material tube 9 along the vertical direction and convey it to the testing device 8.

[0039] The clamping assembly 12 includes a clamping driving part 121 and two clamping arms 122. The clamping driving part 121 is connected to the two clamping arms 122 to drive the two clamping arms 122 to open and close, so as to clamp or loosen the end of the material tube 9. The clamping driving part is preferably a clamping cylinder. The flipping assembly 13 is fixed on one side of the support platform 11 and is connected to the clamping driving part 121 for driving the clamping assembly 12 to rotate. The flipping assembly is a combination of a motor and a transmission belt. Of course, a rotary cylinder can also be used. The two clamping arms 122 can rotate in the open state to change the relative position between the two clamping arms 122 and the material tube 9, so as to clamp the material tube 9 or stagger it from the material tube 9 in the vertical direction Z. At the same time, the two clamping arms 122 can rotate in the closed state to flip the material tube 9.

[0040] The clamping assembly 12 includes a flipping position and an avoiding position on its rotation trajectory. The flipping position is used to facilitate the clamping assembly 12 to clamp the material tube 9, and the avoiding position is used to facilitate the feeding mechanism 2 to clamp the material tube 9 along the vertical direction Z.

[0041] As Figure 3 shown, when the clamping assembly 12 is in the flipping position, the two clamping arms 122 are arranged vertically in the Z direction, and the two clamping arms 122 can be opened and closed under the drive of the clamping driving part 12 to clamp or loosen the end of the material tube 9.

[0042] As Figure 3As shown, when the clamping assembly 12 is in the flipped position and the two clamping arms 122 are in the open state, the clamping arm 122 located at the bottom is lower than the support surface 110, so that the material tube 9 can be pushed laterally between the two clamping arms 122, and the material tube 9 can be located between the two clamping arms 122 without moving the clamp flip assembly 13 and the clamping assembly 12 toward the material tube 9, thereby facilitating the positioning and cooperation of the clamping assembly 12 and the material tube 9.

[0043] like Figure 4 、 Figure 5 As shown, when the clamping assembly 12 is in the flipping position and the two clamping arms 122 are closed to clamp one end of the material tube 9 in the longitudinal direction Y, the material tube 9 is spaced apart from the support surface 110. Driven by the flipping assembly 13, the clamping assembly 12 can flip the material tube 9 to change its orientation through a flipping angle of 180°. The closing of the two clamping arms 122 automatically lifts the material tube 9, separating the material tube 9 from the support surface 110. This prevents the material tube 9 from interfering with the support surface 110 during flipping, ensuring normal flipping of the material tube 9.

[0044] After the material tube 9 is turned over and in place, the two clamping arms 122 move away from each other, and the material tube 9 can be placed back on the supporting platform.

[0045] When the two clamping arms 122 are in the open state, the clamping assembly 12 can rotate between the flipping position and the avoidance position under the drive of the flipping assembly 13. At this time, the rotation of the two clamping arms 122 only changes the relative position with the material tube 9, and does not drive the material tube 9 to flip.

[0046] like Figure 6 As shown, when the clamping assembly 12 rotates to the avoidance position, the two clamping arms 122 are arranged horizontally and are respectively located on both sides of the material tube 9, so that the clamping arms 122 are staggered from the position directly above the material tube 9, thereby facilitating the feeding mechanism 2 to lift the material tube 9 and send it to the testing equipment 8.

[0047] like Figure 7As shown in the figure, an air hole 1220 is provided on the inner side surface of one of the clamping arms 122. The air hole 1220 is connected to a pneumatic device through a pneumatic detector for detecting the air pressure inside the clamping arm 122, and further determining the orientation of the material tube 9. Since a groove is provided on the surface of the material tube 9 where the chip is exposed, when the two clamping arms 122 clamp the material tube 9: if the air hole 1220 contacts the grooved surface of the material tube 9, the pressure inside the air hole 1220 will not change; if the air hole 1220 contacts the other surface of the material tube 9, since there is no groove on this surface, the air hole 1220 will be blocked by the material tube 9, resulting in a change in the pressure inside the air hole 1220. Thus, after clamping the material tube 9, the current orientation of the material tube 9 can be determined according to the pressure change inside the air hole 1220 to determine whether the material tube 9 needs to be flipped. This structure is simple and low-cost, without the need to set up a vision detection mechanism or an infrared detection mechanism on the frame 100, reducing the occupied space of the frame 100.

[0048] A limiting member 123 is provided on the side surface of the clamping driving member 121. The limiting member 123 is integrally L-shaped, and its two arms are respectively a fixing plate 1231 and a guiding plate 1232. The fixing plate 1231 is fixedly connected to the side surface of the clamping driving member 121, and the fixing plate 1231 can be used to facilitate the fixed connection between the limiting member 123 and the clamping driving member 121.

[0049] The plate surface of the guiding plate 1232 is perpendicular to the longitudinal direction, and in the longitudinal direction, the guiding plate 1232 protrudes from the side of the clamping driving member 121 facing the material tube 9. An introducing portion 1233 is provided at the end of the guiding plate 1232 facing away from the fixing plate 1231. The introducing portion 1233 is bent obliquely away from the material tube 9 relative to the guiding plate 1232, so as to facilitate the pushing of the material tube 9 to between the two clamping arms 122 by the cooperation of the introducing portion 1233 and the guiding plate 1232.

[0050] As Figure 8 shown, the feeding mechanism 3 includes a feeding assembly 31, a first moving assembly 32 and a pushing assembly 33. The support platform 11, the pushing assembly 33 and the feeding assembly 31 are arranged in sequence along the transverse direction. The feeding assembly 31 is used for stacking the material tubes 9 and driving multiple material tubes 9 to lift. The first moving assembly 32 is located above the support platform 11 and the feeding assembly 31, and is used for moving the material tubes 9 from the top of the feeding assembly 31 to the support platform 11 one by one. The pushing assembly 33 is used for pushing the material tubes 9 along the transverse direction so that the end of the material tube 9 is located at the flipping avoidance mechanism, specifically, the end of the material tube 9 is located between the two clamping arms 122. Through the above mechanism, the material tubes 9 can be placed on the support platform 11 one by one, and the end of the material tube 9 is pushed between the two clamping arms 122 to facilitate the flipping of the material tube 9.

[0051] Combined with Figure 8 and Figure 9As shown in the figure, the feeding assembly 31 includes a conveying plate 311, a conveying chain 312, a clamping member 313, and a feeding driving member 314. The conveying plate 311 is inclined, and the top end of the conveying plate 311 is biased towards the support platform 11 relative to its bottom end. A strip-shaped hole is provided on the conveying plate 311, and the strip-shaped hole extends along the inclined direction of the conveying plate 311. The conveying chain 312 is arranged at the strip-shaped hole. There are multiple clamping members 313, which are arranged at intervals on the conveying chain 312 and are used for holding multiple stacked material tubes 9. The feeding driving member 314 is connected to the conveying chain 312 and is used to drive the conveying chain 312 and multiple clamping members 313 to move, so as to convey the material tube 9 from bottom to top along the conveying plate 311. The user can place the material tube 9 on several clamping members 313 at the lowered position. The clamping members 313 separate the material tube 9 into multiple groups, and each group contains multiple material tubes 9, which is convenient for the user to place the material tube 9. Then, the feeding driving member 314 drives the conveying chain 312 to lift the material tube 9 to a higher position, which is convenient for the user to load the material tube, with convenient operation and reduced working intensity. The conveying plate 311 is inclined. After the material tube 9 is placed on the clamping member 313, it can lean against the conveying plate obliquely, which can prevent the material tube 9 from tipping over during the conveying process and ensure the stability and reliability of the conveying process.

[0052] There can be two conveying chains 312, arranged longitudinally. The clamping members 313 of the two conveying chains 312 can respectively support both ends of the material tube 9 to ensure the smoothness of the conveying. The feeding driving member 314 can be a motor, which is arranged at the bottom of the conveying chain 312 to ensure the stability of the whole device.

[0053] As Figure 9 shown, it is a schematic structural diagram of the feeding assembly after hiding the conveying plate; the feeding assembly 31 further includes an inner plate 315. The inner plate 315 is located inside the conveying plate 311 and is parallel to it. Four conveying wheels 316 are provided on the clamping member 313, and all four conveying wheels 316 are in contact with the inner plate 315. The four conveying wheels 316 are divided into two groups and are respectively arranged on the longitudinal two sides of the conveying chain 312. The use of the conveying wheels 316 can ensure the stability of the clamping member 313 driving multiple material tubes 9 to move upward.

[0054] When the clamping member 313 is conveyed to the top end of the conveying plate 311, the first moving assembly 32 can clamp the uppermost material tube 9 and move it to the support platform 11.

[0055] As Figure 8As shown, the first moving component 32 includes a first clamping device 321, a first lifting device 322, and a first lateral conveying device 323. The first clamping device 321 is used to clamp the material tube 9. The first lifting device 322 is connected to the first clamping device 321 and is used to drive the first lifting device 322 and the material tube 9 to move up and down, so as to lift and lower the material tube 9. The first lateral conveying device 323 is connected to the first lifting device 322 and is used to drive the first lifting device 322 and the first clamping device 321 to move laterally, so as to drive the material tube 9 to move from above the feeding component 31 to above the support platform 11.

[0056] As Figure 8 As shown, the feeding mechanism 2 is used to send the material tube 9 on the support platform 11 to the testing device 8, and it includes a second clamping device 21, a second lifting device 23, a rotating device 24, a second lateral conveying device 25, and a detecting device 22. The second clamping device 21 is used to clamp the material tube 9. The second lifting device 23 is connected to the second clamping device 21 and is used to drive the second lifting device 23 and the material tube 9 to move up and down, so as to lift and lower the material tube 9. The rotating device 24 is connected to the second lifting device 23 and is used to drive the second lifting device 23 to rotate, so as to rotate the material tube 9 to the same inclination angle as the hopper of the detecting device 22. The second lateral conveying device 25 is connected to the rotating device 24 and is used to drive the rotating device 24 to move laterally, so as to drive the material tube 9 to move from above the support platform 11 to above the hopper.

[0057] Combined with Figure 10As shown in the figure, the detection device 22 is arranged on the second clamping device 21. The detection device 22 includes a detection bracket 220, a first detector 221 and a second detector 222. The detection bracket 220 is fixed to one side of the second clamping device 21. The position of the first detector 221 is higher than that of the second detector 222, and both are arranged on the detection bracket 220. The first detector 221 is arranged horizontally and is used to detect whether there is a material pipe 9 at the second clamping device 21. When the second clamping device 21 moves to the support platform 11, the first detector 221 can detect whether there is a material pipe 9 on the support platform 11 so as to start the second clamping device 21. When the second clamping device 21 is moving, the first detector 221 can detect the material pipe 9 clamped by the second clamping device 21 in real time so as to stop the machine in time in case of abnormal situations such as the material pipe 9 falling. The second detector 222 is arranged horizontally and is used to detect whether there is a material pipe 9 on the hopper. Since the second detector 222 is lower than the first detector 221, when the second clamping device 21 clamps the material pipe 9 and moves to the hopper and is about to put down the material pipe 9, the second detector 222 located below can detect whether there is a material pipe 9 remaining on the hopper. If there is a material pipe 9 on the hopper, the second lifting device 23 stops operating to avoid the two material pipes 9 colliding due to the second clamping device 21 continuing to move downward. If there is no material pipe 9 on the hopper, the second lifting device 23 drives the second clamping device 21 to move downward to a specified position and then releases the material pipe 9. In this way, it can be avoided that the previous material pipe 9 has not been removed for detection and the next material pipe 9 is directly stacked on the previous material pipe 9, affecting the normal progress of detection.

[0058] A first elongated hole 2201 and a second elongated hole 2202 are arranged on the detection bracket 220, and both the first elongated hole 2201 and the second elongated hole 2202 are arranged vertically; the first detector 221 is vertically adjustably installed in the first elongated hole 2201, and the second detector 222 is vertically adjustably installed in the second elongated hole 2202. By using the first adjustment hole and the second adjustment hole, the positions of the first detector 221 and the second detector 222 on the detection bracket 220 can be conveniently adjusted so that the first detector 221 and the second detector 222 can correspond to the position of the material pipe 9 according to the thickness of the material pipe 9.

[0059] In summary, although the present utility model has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present utility model. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
