DETAILED DESCRIPTION

[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0035] Reference Figures 1 to 7 As shown, the present invention provides a multi-model beam sorting mechanism, comprising a beam storage unit 10, a beam picking unit 20 and a beam receiving unit 30, wherein:

[0036] Reference Figure 1As shown, the beam storage unit 10 is provided with a plurality of storage spaces 11, which are used to store beams, and a plurality of beams are stacked in the storage space 11; in the embodiment provided in the present application, the size and diameter of each storage space 11 can be adjusted, so as to facilitate the simultaneous storage of beams of various specifications.

[0037] Reference Figure 4 and Figure 5 As shown, the beam picking unit 20 includes a first driving component 21 and a beam clamping component 22. There are multiple beam clamping components 22, and the multiple beam clamping components 22 correspond one to one to the multiple storage spaces 11. The beam clamping component 22 is used to clamp or release a single beam. The first driving component 21 is connected to the multiple beam clamping components 22 to drive the beam clamping component 22 to vertically lift and lower along a first preset path. In the embodiment provided in the present application, the first preset path is a lifting and lowering movement in the direction of gravity.

[0038] On the one hand, the beam clamping assembly 22 descends into the beam storage unit 10 to clamp the beam placed in the corresponding storage space 11. After clamping the beam, the first drive assembly 21 drives the beam clamping assembly 22 to rise, and then releases the clamped beam to the beam receiving unit 30. On the other hand, the beam picking unit 20 can simultaneously clamp multiple beams of the same specification or beams of different specifications. Multiple beam clamping assemblies 22 can descend to clamp beams at the same time, working independently without interfering with each other. After clamping is completed, they are simultaneously raised by the first drive assembly 21.

[0039] Reference Figure 1 、 Figure 4 as well as Figure 5 As shown, the beam receiving unit 30 includes a second drive component 31 and a receiving plate 32. The second drive component 31 is connected to the receiving plate 32 to drive the receiving plate 32 to move laterally along a second preset path. The second preset path is a movement in the horizontal direction, and the first preset path and the second preset path have an intersection. In the embodiment provided in the present application, when the beam picking unit 20 clamps the beam back to the highest position, the receiving plate 32 moves to the bottom of the beam clamping component 22 under the action of the second drive component 31. At this time, the first preset path and the second preset path intersect. After receiving the beam, the receiving plate 32 returns to enter the next process.

[0040] In the examples provided in this application, reference is made to Figure 4 and Figure 5 As shown, the first driving assembly 21 includes a first bracket 211, a first driving motor 212, a first driving screw 213, a first screw nut 214, a first rod 215, a first guide rail 216 and a second rod 217, wherein:

[0041] The first driving screw rod 213 is rotatably provided on the first bracket 211 through a bearing seat, the output shaft of the first driving motor 212 is connected to the first driving screw rod 213, the first screw rod nut 214 is threadedly connected to the first driving screw rod 213, and the first rod body 215 is fixedly connected to the first screw rod nut 214; when the first driving motor 212 is started, it drives the first driving screw rod 213 to rotate, and the first screw rod nut 214 moves up and down along the first driving screw rod 213, thereby driving the first rod body 215 to perform lifting motion.

[0042] There are multiple second rods 217, and the multiple second rods 217 correspond one to one with the multiple beam clamping assemblies 22. Each second rod 217 is provided with a beam clamping assembly 22. After each second rod 217 performs free fall motion under the action of gravity and falls above the beam of the corresponding storage space 11, it determines the beam to be clamped and clamps the beam through the beam clamping assembly 22. After the clamping is completed, the first rod 217 rises under the drive of the first drive motor 212, thereby driving the multiple second rods 217 to rise.

[0043] Reference Figure 4 and Figure 5 As shown, multiple first guide rails 216 are all arranged on the first bracket 211, the extension direction of the first guide rails 216 is parallel to the extension direction of the first driving screw rod 213, the multiple first guide rails 216 correspond one-to-one with the multiple second rod bodies 217, the second rod bodies 217 are slidably fitted on the first guide rails 216, and on the sliding path of the second rod body 217, the second rod body 217 abuts against the first rod body 215. When picking up the beam, the second rod 217 performs free fall along the first guide rail 216 and descends to the top of the beam. After the second rod 217 clamps the beam, the first rod 215 moves upward until it abuts against all the second rods 217. Under the support of the first rod 215, all the second rods 217 rise. When the second rods 217 rise to the highest position, the receiving plate 32 moves to the bottom of the beam picking unit 20, and the beam clamping assembly 22 releases the beam onto the receiving plate 32. After the receiving plate 32 transfers the beam to the next process, the second rod 217 continues to work and clamps the next beam.

[0044] Further, refer to Figure 4 As shown, the beam clamping assembly 22 includes an electromagnet 221 and a finger cylinder 222. The electromagnet 221 and the finger cylinder 222 are both arranged on the second rod body 217. In the embodiment provided in the present application, the electromagnet 221 includes two, which are respectively located at the two ends of the second rod body 217, so as to facilitate the stable adsorption of the beam. Two clamping claws 2221 are provided on the output end of the finger cylinder 222. The two clamping claws 2221 are arranged relative to each other and can be close to or away from each other.

[0045] When clamping the beam, after the second rod body 217 descends to the top of the beam, the two electromagnets 221 of the corresponding second rod body 217 are activated to adsorb the beam, and the two claws 2221 of the finger cylinder 222 approach each other to clamp the uppermost beam, thereby separating the uppermost beam from the lower beam. When the beam is clamped to the highest position and the receiving plate 32 reaches the bottom of the beam picking unit 20, the two claws 2221 of the finger cylinder 222 move away from each other, and at the same time, the electromagnet 221 releases the magnetic force, thereby releasing the beam onto the receiving plate 32.

[0046] In the examples provided in this application, reference is made to Figure 1 and Figure 4 As shown, the second drive assembly 31 includes a second guide rail 311, a second bracket 312, a second drive motor 313, a drive gear 314, and a drive rack 315. The second guide rail 311 is mounted on the second bracket 312, the receiving plate 32 is slidably engaged with the second guide rail 311, and the drive rack 315 is fixed to the receiving plate 32. The output shaft of the second drive motor 313 is connected to the drive gear 314, which meshes with the drive rack 315. When the second drive motor 313 is activated, the drive gear 314 rotates, thereby driving the drive rack 315 to move. The receiving plate 32 slides back and forth along the second guide rail 311 as the drive rack 315 moves.

[0047] Further, refer to Figure 1 、 Figure 4 and Figure 5 As shown, the receiving plate 32 is provided with a plurality of receiving units 33, which are used to receive a single beam. The plurality of receiving units 33 correspond one-to-one with the plurality of beam clamping assemblies 22. The receiving unit 33 includes a plurality of limit seats 331, which together form a receiving space 334. In the embodiment provided in the present application, the limit seats 331 include four, which are connected in sequence to form a rectangular structure to adapt to the shape of the beam. A single beam can be accommodated in the receiving space 334. The receiving space 334 is provided with a positioning assembly 332 and a pushing assembly 333. The positioning assembly 332 is provided with a positioning pin 3321, which is adapted to a preset positioning hole on the beam. The pushing assembly 333 is used to push the beam located in the receiving space 334 so that the preset positioning hole on the beam is aligned with the positioning pin 3321.

[0048] When the receiving plate 32 receives beams of the same specifications, the beams are first placed on the corresponding receiving units 33 using the beam clamping assembly 22. The pusher assembly 333 then pushes the beams so that the positioning pins 3321 on the positioning assembly 332 align with the preset positioning holes on the beams, thereby securing the beams within the receiving units 33. When the receiving plate 32 needs to simultaneously receive beams of different specifications, the pusher assemblies 333 in multiple receiving units 33 push the corresponding beams so that the centerlines of all the beams coincide. The beams are then fixed in place using the corresponding positioning assemblies 332, and the process then proceeds to the next step or layout according to process requirements.

[0049] Reference Figure 2 、 Figure 3 、 Figure 6 as well as Figure 7 As shown, in a feasible embodiment, the limiting seat 331 includes a first bottom plate 3311, an elastic recovery member 3312, a limiting column 3313 and a vertical plate 3314, wherein:

[0050] Multiple vertical plates 3314 are provided, and the plurality of vertical plates 3314 are annularly spaced and arranged on the outer circumference of the limiting pillar 3313. The vertical plates 3314 extend in a direction parallel to the extension direction of the limiting pillar 3313, and the widths of the plurality of vertical plates 3314 vary. In the embodiment provided herein, there are four vertical plates 3314, each with a different width. The vertical plates 3314 of each limiting seat 331 can be adjusted according to the width of the crossbeam, so that the distance between two adjacent limiting seats 331 within a receiving unit 33 can accommodate crossbeams of different widths. Each vertical plate 3314 also has a beveled edge at the top, which serves as a guide when placing the crossbeam, facilitating smooth placement of the crossbeam into the receiving space 334.

[0051] The first base plate 3311 is fixed on the supporting plate 32. A plurality of fixing grooves 3315 are provided on the top of the first base plate 3311. The plurality of fixing grooves 3315 are matched one by one with the plurality of vertical plates 3314. The bottom end gap of the vertical plate 3314 fits in the fixing groove 3315. When adjusting the vertical plate 3314, the rotating limit column 3313 rotates the appropriate vertical plate 3314 to the corresponding position, and then the vertical plate 3314 is inserted into the fixing groove 3315.

[0052] In one feasible embodiment, a first through hole 3316 is provided through the first bottom plate 3311, and the limiting post 3313 is loosely fitted in the first through hole 3316. The bottom end of the limiting post 3313 passes through the first through hole 3316 and is connected to the elastic recovery member 3312, so that the limiting post 3313 can elastically reciprocate along the axial direction. When adjusting the vertical plate 3314, this is achieved by pulling the limiting post 3313 upward and then rotating it. When the desired vertical plate 3314 reaches the preset position, the limiting post 3313 is lowered, and the limiting post 3313 is reset under the action of the elastic recovery member 3312, and the position of the vertical plate 3314 is fixed.

[0053] Reference Figure 3 As shown, the positioning assembly 332 includes a fixed seat 3322, a positioning seat 3323 and a positioning pin switching seat 3324. The fixed seat 3322 is arranged on the receiving plate 32. A third guide rail 3325 is provided on the fixed seat 3322. The positioning seat 3323 slides on the third guide rail 3325. When receiving the beam, in addition to considering the beam width requirements, it is also necessary to adjust the length of the receiving space 334 according to the length of the beam. After the pushing assembly 333 fixes the position of one end of the beam, the positioning seat 3323 is adjusted in the position of the fixed seat 3322 by moving the positioning seat 3323 along the third guide rail 3325 to adapt to beams of different lengths placed in the corresponding receiving space 334. A groove 3326 is provided on the positioning seat 3323, and the positioning pin switching seat 3324 is provided in the groove 3326. The positioning pin switching seat 3324 can move along the groove 3326, so that the appropriate positioning pin 3321 can be quickly switched according to the width of the beam, thereby improving sorting efficiency.

[0054] Continue to refer to Figure 3 As shown, a plurality of positioning pins 3321 are provided on the positioning pin switching seat 3324, and the diameters of the plurality of positioning pins 3321 are different. Due to the differences in the specifications of the beams, when undertaking different beams, the specifications of the positioning pins 3321 used are also different. It is necessary to quickly switch the positioning pins 3321 according to the specifications of the beams. Therefore, a plurality of positioning pins 3321 are set on the positioning pin switching seat 3324 to facilitate quick switching.

[0055] Reference Figure 1As shown, in a feasible embodiment, the beam storage unit 10 includes a third bracket 13, a base plate 12 and a width-limiting shaft 14. The base plate 12 is provided on the third bracket 13. There are multiple width-limiting shafts 14, and the multiple width-limiting shafts 14 are detachably fixed to the base plate 12. The storage space 11 is formed by enclosing a preset number of width-limiting shafts 14. In the embodiment provided by the present application, a plurality of through-hole pairs are provided on the base plate 12, and each through-hole pair includes two second through-holes 121. The spacing between each pair of second through-holes 121 is different. According to the specifications of the beams to be stored, the width-limiting shaft 14 is installed in the through-hole pair with suitable spacing by plugging and unplugging to form a storage space 11 suitable for storing beams of corresponding specifications, so that the storage space 11 can be quickly switched according to the specifications of the beams, which has better adaptability.

[0056] Furthermore, a limiting plate 15 is provided on the third bracket 13 to limit the axial movement of the beam. This plate ensures that the beams are neatly stacked within the corresponding storage spaces 11. Even if the beams do move axially, the range of their movement is limited, thereby ensuring smooth sorting.

[0057] The working process of the beam sorting mechanism of the present application is as follows: beams of various specifications are stacked in the multiple storage spaces 11 of the beam storage unit 10. When a preset beam needs to be picked up, the multiple second rods 217 of the beam picking unit 20 are lowered to the top of the corresponding beam under the action of gravity. The electromagnet 221 of the beam clamping assembly 22 on the second rod 217 is started. After the two electromagnets 221 adsorb the two ends of the beam, the uppermost beam is clamped by the two clamping claws 2221 of the finger cylinder 222. Then the first driving motor 212 of the first driving assembly 21 is started, and the first driving screw 213 rotates accordingly, driving the first screw nut 214 to rise, thereby driving the first rod 215 to rise. The first rod 215 rises until it abuts against all the second rods 217 and continues to rise, driving all the second rods 217 to move upward along the first guide rail 216. When the second rod 217 moves to the highest position, After the lifting of the lifting device 314, the lifting device 314 is lifted up and the lifting device 314 is lifted up, so that the lifting device 314 can be lifted up and the lifting device 314 can be lifted up.

[0058] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings.
