DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 A medical aluminum tube feeding and conveying device in this embodiment includes a workbench 1, on which a feeding mechanism 2 and a conveying mechanism 3 are provided. The feeding mechanism 2 transfers the aluminum tube to the conveying mechanism 3, and then the conveying mechanism 3 conveys the aluminum tube in sequence along the conveying path to various processing equipment for processing.

[0027] Several aluminum tubes are placed in the same material frame, and a slot is provided in the material frame to make the aluminum tubes stand upright. The feeding mechanism 2 can deliver the aluminum tubes in the material frame to the conveying mechanism 3. After the material frame is empty, the empty frame can be transferred. Figure 1 As shown, the feeding mechanism 2 includes three limit bars 201 fixed on the workbench 1 and parallel to each other. The middle limit bar 201 is wider than the two side limit bars 201, and the two side limit bars 201 respectively form two columns of channels for the movement of two columns of material frames, one column of channels is used for material frame loading, and the other column of channels is used for material frame unloading. The top surfaces of the two limit bars 201 corresponding to the material frame loading channels are fixed with guide bars 202. The front ends of a pair of guide bars 202 are relatively inclined to facilitate the material frame filled with aluminum tubes to enter the column of channels. The above-mentioned limit bars 201 are also fixed with positioning bars 203 arranged vertically therewith. The corresponding material frame can be positioned by the positioning bars 203 when it moves to the front end. The workbench 1 is also provided with a transfer structure for transferring the aluminum tubes in the material frame.

[0028] The two rows of channels can be connected to two sets of conveyor belts respectively. One set of conveyor belts is used to transfer the material frames filled with aluminum tubes to the corresponding channels, and the other set of conveyor belts is used to transfer the empty frames pushed out of the corresponding channels, thus realizing fully automatic loading. The empty frames can also be automatically recycled, which is more efficient.

[0029] After the material frame filled with aluminum tubes enters the feeding channel and is positioned by the positioning bar 203, the transfer structure can be used to clamp the tubes to the conveying mechanism 3 for conveying. Figure 3 As shown, the transfer structure includes a transfer frame 204 fixed on the workbench 1, an X-axis linear module 205 is fixed on the transfer frame 204, a Y-axis linear module 206 driven by the X-axis linear module 205 to perform horizontal linear motion is fixed to the output end of the X-axis linear module 205, a Z-axis linear module 207 driven by the Y-axis to perform linear motion on the Y-axis is fixed to the output end of the Y-axis linear module 206, a row of clamps 208 driven by the Z-axis to perform linear motion on the Z-axis is fixed to the output axis of the Z-axis linear module 207, and the clamps 208 are driven by the X-axis linear module 205, the Y-axis linear module 206 and the Z-axis linear module 207 to move flexibly in all directions, so as to facilitate the movement of the aluminum tubes in the material frame to the conveying mechanism 3 for conveying.

[0030] After the aluminum tubes in the material frame are transferred, the empty frame can be pushed into another channel to be recycled. The guide bar 202 is fixed on the limit bar 201 through a pair of mounting blocks 209. Figure 2 As shown, the mounting block 209 can raise the guide bar 202 so that the guide bar 202 can guide the aluminum tube in the material frame and can also avoid the empty frame when it is transferred. The middle limit bar 201 is shorter than the limit bars 201 on both sides, which facilitates the empty frame to move from the loading channel to the unloading channel.

[0031] As for how to move the empty frame from the loading channel to the unloading channel, Figure 3 As shown, a first-stage frame pushing cylinder 210 is fixed on the workbench 1, a pair of driving rods 211 are fixed to the output end of the first-stage frame pushing cylinder 210, and a first-stage pushing block 212 is commonly fixed to the other end of the pair of driving rods 211. An avoidance groove for linear movement of the first-stage pushing block 212 is provided on the side limit strip 201. A guide seat 213 fixed to the workbench 1 is sleeved on the outer side of the driving rod 211 to guide the driving rod 211. By driving the first-stage pushing block 212 to move linearly through the driving rod 211, the empty frame in the loading channel can be pushed into the unloading channel.

[0032] How to push out the empty frame in the feeding channel? Figure 2 , Figure 4 As shown, a pair of secondary push blocks 214 located in the unloading channel and capable of linear movement are provided on the workbench 1. A secondary push frame cylinder 215 is fixed to the bottom surface of the workbench 1. The output end of the secondary push frame cylinder 215 is fixed to the secondary push block 214. The secondary push block 214 can be driven by the secondary push frame cylinder 215. The secondary push frame cylinder 215 can be used to drive the secondary push block 214 to push the empty frame to move in the reverse direction. There are also two rows of long holes on the workbench 1 for the secondary push block 214 to move linearly.

[0033] In addition, a positioning block 216 that can move up and down is also provided behind the middle limit bar 201. The positioning block 216 is driven by a positioning cylinder 217. The fixed end of the positioning cylinder 217 is fixed on the workbench 1, and the output end of the positioning cylinder 217 is fixed on the positioning block 216. The positioning block 216 can be driven to move up and down by the positioning cylinder 217. There is also an avoidance opening on the workbench 1 for the positioning block 216 to move up and down. The positioning block 216 is pushed out to position the material frame.

[0034] The conveying mechanism 3 includes three long support seats 301 fixed on the workbench 1, forming two rows of transport channels. The two rows of transport channels are respectively transport channel 1 and transport channel 2 which are distributed in parallel. A number of supporting bars 302 are arranged between adjacent long support seats 301. The number of supporting bars 302 can move in a circular motion, and there are placement grooves for placing aluminum tubes on the supporting bars 302. When the aluminum tube is placed in the placement groove on the supporting bar 302, it can be moved through the supporting bar 302, thereby transporting the aluminum tube.

[0035] Support grooves are provided on the opposite sides of adjacent long strip support seats 301, which are used to support the load-bearing bars 302 and allow the load-bearing bars 302 to move horizontally linearly. Pushing cylinders 303 are provided at the ends of the two rows of transport channels. One pushing cylinder 303 is arranged at the tail end of transport channel one, and the other pushing cylinder 303 is arranged at the head of transport channel two. The pushing cylinder 303 at one end is pushed out to push the load-bearing bars 302 in the corresponding transport channel to move. The adjacent load-bearing bars 302 push each other, so that the aluminum tubes in the load-bearing bars 302 can be moved in sequence, and the aluminum tubes can be sent to various processing equipment for processing in sequence.

[0036] As for how the plurality of supporting bars 302 are moved in a circular motion, the two rows of transport channels are further provided with two sets of material shifting structures 304, one set of material shifting structures 304 is arranged at the tail of transport channel one, and the other set of material shifting structures 304 is arranged at the head of transport channel two. When the pushing cylinder 303 pushes the supporting bars 302 in transport channel one, the supporting bars 302 in transport channel one move in sequence, and the supporting bars 302 at the end are pushed out, and the corresponding material shifting structures 304 can be used to shift the above-mentioned supporting bars 302 to the transport channel one. In channel two, at the same time, when another pushing cylinder 303 pushes the supporting bar 302 in transport channel two, the supporting bar 302 in transport channel two also moves in sequence and in the opposite direction to the movement trajectory of the supporting bar 302 in transport channel one. At the same time, when the supporting bar 302 at the end of transport channel two is pushed out, the corresponding material-push structure 304 can push the supporting bar 302 into transport channel one. The above operation is repeated in a cycle, and a number of supporting bars 302 can perform circular movement in transport channel one and transport channel two.

[0037] Specific as Figure 5 As shown, the material-moving structure 304 includes a material-moving cylinder 3041 fixed on the workbench 1, and a material-moving plate 3042 is fixed to the output shaft of the material-moving cylinder 3041. When the material-moving cylinder 3041 is pushed out, the end portion of one row of supporting bars 302 can be pushed to another row through the material-moving plate 3042, thereby realizing a circular circular movement, so that the aluminum tubes placed on the supporting bars 302 are moved to each processing equipment in turn.

[0038] By adopting the above-mentioned medical aluminum tube feeding and conveying device, the aluminum tube is automatically fed and sent to various processing equipment in turn for processing. The specific feeding and conveying method is as follows:

[0039] The material frame filled with aluminum tubes is sent to the channel between the corresponding two limit bars 201 until it contacts the positioning bar 203. Then, the X-axis linear module 205, the Y-axis linear module 206 and the Z-axis linear module 207 can be used to drive the clamping claw 208 to move to the corresponding aluminum tube to clamp the aluminum tube and transfer it to the bearing bar 302. The bearing bar 302 transports the aluminum tube. After the aluminum tubes in the material frame are emptied, the first-stage push frame cylinder 210 drives the first-stage push block 212 through the driving rod 211 to push the empty frame to another channel. Then, the second-stage push frame cylinder 215 drives the second-stage push block 214 to push the empty frame in the opposite direction. The entire loading process is more automated, and each step is more closely connected, which helps to improve the loading efficiency.

[0040] After the plurality of aluminum tubes are sent into the supporting bars 302 , the plurality of supporting bars 302 can perform circular movement, so that the aluminum tubes to be processed are sequentially sent to various processing equipment for processing.

[0041] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
