Description

Technical Field

[0001] The invention relates to the technical field of bird thorn prevention processing equipment, in particular to an automatic bird thorn prevention production line. Background Art

[0002] Bird-proof spikes are a tool that restricts bird activities. They are mainly used on household solar panels. Solar panels are generally installed on the roofs of residents. The solar panels are tilted so that there will be a gap between them and the roof, and birds can easily build nests in the gaps. Once birds build nests there, the feces and other debris produced by their activities will not only easily dirty the roof, but also easily corrode the solar panel frame and other structures. Therefore, bird-proof spikes are needed to block these gaps to block the activities of birds. At present, when producing and assembling bird-proof spikes, it is necessary to make a plastic mounting plate and then make a steel wire. Into straight wire and V-shaped wire, then manually install these straight wires or V-shaped wires on the mounting plate of the bird-proof thorns in turn. After the straight wire is installed, it is necessary to use tools to tighten the straight wire to prevent it from falling on the mounting plate. After the V-shaped wire is installed, it is also necessary to use tools to adjust the size of its opening angle. The whole process requires workers to assemble them one by one in order. The whole process requires a lot of manpower, which not only increases the workload of workers, increases production costs, reduces assembly efficiency, but also is not conducive to the control of the quality of bird-proof thorns, which brings great inconvenience to the production and manufacturing of bird-proof thorns.

[0056] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other unless there is a conflict.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0058] like Figure 1-20 As shown, the present embodiment describes an automatic production line for preventing bird thorns, comprising a circulating conveying mechanism 1 for conveying an anti-bird thorn mounting plate 10, and an anti-bird thorn straight wire cutting mounting portion 2, an anti-bird thorn V-shaped wire cutting mounting portion 3, and an anti-bird thorn V-shaped wire secondary processing portion 4 are sequentially arranged above the circulating conveying mechanism 1 from back to front.

[0059] The circulating conveying mechanism 1 includes a frame 8, on which two conveying chains 9 are symmetrically arranged. Several placement strips 11 for placing anti-bird thorn mounting plates 10 are evenly distributed between the conveying chains 9. The placement strips 11 are provided with perforations in the vertical direction for convenient passage of anti-bird thorn straight wires 19, and the front and rear sides of the placement strips 11 are provided with avoidance grooves 11a for convenient passage of anti-bird thorn V-shaped wires 20.

[0060] A positioning seat is provided on the frame 8 at a position corresponding to the upper placement bar 11. The positioning seat includes a base plate 12 provided on the frame 8, a lifting block 13 provided on the base plate 12, a positioning pin provided on the lifting block 13, and a positioning hole for facilitating the insertion of the positioning pin at the lower end of the placement bar 11. The lifting block 13 is controlled to move up and down by a first cylinder 14. The first cylinder 14 is located in the base plate 12. The movement of the piston rod of the first cylinder 14 drives the lifting block 13 to move up and down. When the placement bar 11 rotates to the top of the lifting block 13, the lifting block 13 rises and is plugged into the lower end of the placement bar 11, thereby completing the fixation of the position of the placement bar 11.

[0061] The positioning seat is set at the corresponding positions of the feeding mechanism 7, the anti-bird thorn straight wire cutting installation part 2, the anti-bird thorn V-shaped wire cutting installation part 3, and the anti-bird thorn V-shaped wire secondary processing part 4. When loading and conveying are carried out and running to the processing station, the placement strip 11 at the corresponding position is positioned.

[0062] A rotating rod 15 is provided on the frame 8 at a position corresponding to the outer side of the conveyor chain 9. The rotating rod 15 is driven to rotate by the second cylinder 16. A stopper 17 is provided on the rotating rod 15 at positions corresponding to both sides of the placement bar 11. Positioning grooves adapted to the stopper 17 are provided on both sides of the placement bar 11. One end of the second cylinder 16 is hinged to the frame 8, and the piston rod of the second cylinder 16 is hinged to the upper connecting block of the rotating rod 15. When the piston rod of the second cylinder 16 extends, it drives the rotating rod 15 to rotate forward and backward, thereby driving the stopper 17 to be fixed on both sides of the placement bar 11, and also fixing the position of the placement bar 11;

[0063] Positioning clamps 18 are also provided on the front and rear sides of the placement bar 11. The positioning clamps 18 include a mounting block 18a fixedly connected to the placement bar 11. A retractable limiting piece 18b is provided at the upper end of the mounting block 18a. One end of the limiting piece 18b is set in the mounting block 18a, and the other end of the limiting piece 18b extends to the top of the placement bar 11. The limiting piece 18b clamps the anti-bird thorn mounting plate 10 on the placement bar 11.

[0064] The anti-bird thorn straight wire cutting mounting part 2 includes a first support frame 21 arranged above the conveying chain 9, a first mounting frame 22 which can be moved left and right is arranged on the first support frame 21, a first wire feeding mechanism is arranged on the first mounting frame 22, a straight wire cutting processing part is arranged on the first mounting frame 22 at a position corresponding to the bottom of the first wire feeding mechanism, a straight wire compacting part is arranged on the first mounting frame 22 at a position corresponding to the left side of the straight wire cutting processing part, and a straight wire fastening part is arranged on the left side of the straight wire compacting part.

[0065] Two first slide rails 23 are provided on the top of the first support frame 21 along the left and right directions. The first mounting frame 22 is mounted on the first slide rails 23. A first rack 24 is provided between the first slide rails 23. The first mounting frame 22 is provided with a first servo motor 25. The driving end of the first servo motor 25 is vertically downward and is provided with a first gear on the driving end. The first gear is engaged with the first rack 24.

[0066] The first servo motor 25 rotates and drives the first gear to rotate along the first rack 24 , thereby driving the first mounting bracket 22 to move along the first slide rail 23 .

[0067] The first wire feeding mechanism includes a second servo motor 26 provided on a vertical plate of the first mounting frame 22, a first guide wheel 27 provided at a driving end of the second servo motor 26, a first driven wheel 28 provided on the vertical plate of the first mounting frame 22 at a position corresponding to one side of the first guide wheel 27, the first guide wheel 27 and the first driven wheel 28 being linked by a connecting gear, annular grooves being provided on the surfaces of the first guide wheel 27 and the first driven wheel 28, the steel wire passing through the groove between the first guide wheel 27 and the first driven wheel 28, the steel wire to be processed is transported and cut by the first guide wheel 27 and the first driven wheel 28 and made into the anti-bird thorn straight wire 19;

[0068] The straight wire cutting processing section includes a first knife seat 29, which reciprocates left and right along the vertical plate of the first mounting frame 22. The first knife seat 29 is provided with a first cutter 30 on the side corresponding to the bottom of the first wire feeding mechanism. The first cutter 30 is located at the lower end of the first knife seat 29. A processing block 31 is provided on the left side of the first knife seat 29. The anti-bird thorn straight wire 19 passes through the gap between the first knife seat 29 and the processing block 31. Extrusion blocks 32 are symmetrically provided on the upper end of the first knife seat 29 and the upper end of the processing block 31. The extrusion blocks 32 on both sides cooperate to form a flat head 19a at the upper end of the anti-bird thorn straight wire 19.

[0069] The first knife seat 29 can be moved left and right by a cylinder, or can be hinged to the first knife seat 29 by a motor and an eccentric rod, thereby controlling the movement of the first knife seat.

[0070] When the bird-proof thorn straight wire 19 is being made, the steel wire is first fed through the first wire feeding mechanism, and the steel wire passes between the first knife seat 29 and the processing block 31. As the steel wire is fed, the first knife seat 29 will continuously reciprocate. As the first knife seat 29 moves toward the side of the processing block 31, the first cutter 30 will cut the steel wire. The cut steel wire forms the bird-proof thorn straight wire 19 and falls into the bird-proof thorn mounting plate 10 on the lower placement strip 11. At the same time, the first knife seat 29 and the extrusion block 32 on the processing block 31 will move against each other. This cooperation squeezes the steel wire, thereby deforming it to produce a flat head 19a. As the steel wire is conveyed, when the flat head 19a just moves downward to the bottom of the first cutter 30, the first cutter 30 cuts the steel wire, and the bird-proof thorn straight wire 19 formed after cutting falls down, and the flat head 19a is squeezed, and its diameter becomes wider, so that the bird-proof thorn straight wire 19 falls directly on the bird-proof thorn mounting plate 10. When the bird-proof thorn straight wire 19 is installed, the cut bird-proof thorn straight wire 19 is placed in the bird-proof thorn mounting plate 10 from left to right.

[0071] The straight wire compacting unit includes a third cylinder 33 disposed on the left side of the processing block 31. The piston rod of the third cylinder 33 is vertically downwardly disposed, and a pressing plate 34 is disposed on the piston rod of the third cylinder 33.

[0072] The pressing plate 34 is used for operations after cutting the bird-proof thorn straight wire. As the first mounting frame 22 moves, the pressing plate 34 will produce a downward pressing action after cutting and inserting the bird-proof thorn straight wire 19, thereby preventing individual bird-proof thorn straight wires 19 from being stuck and not falling smoothly into the bird-proof thorn mounting plate 10. The pressing plate 34 can push the bird-proof thorn straight wire 19 to be smoothly inserted into the bird-proof thorn mounting plate 10.

[0073] The straight wire fastening portion includes a fourth cylinder 35 arranged on the left side of the third cylinder 33. The piston rod of the fourth cylinder 35 is arranged vertically downward. An extrusion head 36 is provided on the piston rod of the fourth cylinder 35. The extrusion head 36 presses and clamps the flat head 19a into the anti-bird thorn mounting plate 10.

[0074] The extrusion head 36 punches the position where the bird-proof thorn straight wire 19 is installed. The downward pressure generated by the extrusion head 36 will punch the flat head 19a downward, and the flat head 19a will be firmly stuck in the mounting hole of the bird-proof thorn mounting plate 10, thereby preventing the bird-proof thorn straight wire from detaching from the bird-proof thorn mounting plate.

[0075] The anti-bird thorn V-shaped wire cutting mounting part 3 includes a second support frame 37 arranged above the conveying chain 9, a second wire feeding mechanism is arranged on the front side of the second support frame 37, a V-shaped wire cutting processing part is arranged on the second support frame 37 at a position corresponding to the rear side of the second wire feeding mechanism, a second mounting frame 38 that can move forward and backward is arranged above the second support frame 37, a position-adjustable working arm 39 is arranged on the second mounting frame 38, and an anti-bird thorn V-shaped wire mounting mechanism is arranged at the lower end of the working arm 39, and an auxiliary mounting platform 40 is arranged on the second support frame 37 at a position corresponding to the rear side of the V-shaped wire cutting processing part.

[0076] The second wire feeding mechanism includes a bracket 41 arranged on both sides of the front end of the second support frame 37, and a third servo motor 42 is provided at one end of the bracket 41 facing the outside of the conveying chain 9. A second guide wheel 43 is provided on the side opposite to each other of the bracket 41, and a second driven wheel 44 is provided on the bracket 41 at a position above the corresponding second guide wheel 43. The second guide wheel 43 and the second driven wheel 44 are also linked by a connecting gear. The outer surfaces of the second guide wheel 43 and the second driven wheel 44 are also provided with an annular groove. The steel wire passes through the groove between the second guide wheel 43 and the second driven wheel 44. The conveying method of the steel wire is similar to the above-mentioned conveying method. The steel wire clamped by the second guide wheel and the second driven wheel enters the subsequent V-wire cutting processing part;

A plurality of material receiving grooves 56a are also evenly distributed along the horizontal direction of the material receiving rod 56, and the pushed bird-proof V-shaped wire 20 falls on the material receiving groove 56a in sequence;

[0078] When the second cutter block 49 moves down, the pressing die 51 on the second cutter block 49 presses down and deforms the cut wire. Under the cooperation of the pressing groove 51a on the pressing die 51 and the top of the placing table 47, the cut wire can be shaped into a V-shaped structure. When the second cutter block 49 moves up, the pushing plate 53 will push the formed bird-proof V-shaped wire down on the placing table 47 under the action of the cylinder. The angle of the pushed bird-proof V-shaped wire 20 is just stuck in the receiving groove 56a of the receiving rod 56. After the material is connected, the conveying crawler 54 drives the receiving rod 56 to move into the second supporting frame 37, and then the receiving groove 56a on the receiving rod 56 receives the formed bird-proof V-shaped wire 20 in turn.

[0079] Second slide rails 57 are provided on both sides of the top of the second support frame 37. The second mounting frame 38 is provided on the second slide rails 57.

Clamping plates 65 for clamping the bird-proof V-shaped wire 20 are provided on the front and rear sides of the clamping platform 64. A plurality of clamping grooves 65a are evenly distributed on the clamping plates 65. The clamping grooves on the clamping plates 65 on both sides cooperate with each other to form clamping holes for clamping the bird-proof V-shaped wire 20. The clamping plates are opened and closed by the eighth cylinder 66. A ninth cylinder 67 is further provided at the lower end of the extension arm 39b at a position above the corresponding clamping platform 64. The piston rod of the ninth cylinder 67 is vertically downward and a pressing bar 68 is provided at the end of the piston rod.

[0081] When the working arm 39 is working, the working arm 39 is controlled to move forward, backward, left and right in the second support frame 37 through the cooperation between the lead screw and the motor. When the material receiving rod 56 on one side is full of the processed anti-bird thorn V-shaped wire 20, the working arm 39 will move to the top of the material receiving rod 56 at that location, and then, driven by the sixth servo motor 63, the extension arm 39b is controlled to move downward, and the clamping plate 65 at the lower end of the extension arm 39b moves to the anti-bird thorn V-shaped wire 20, and then the clamping plates 65 on both sides are retracted under the drive of the cylinder, and the two clamping plates 65 cooperate to clamp the anti-bird thorn V-shaped wire 20 on the material receiving rod 56, and then the extension arm 39b moves upward, thereby grabbing the anti-bird thorn V-shaped wire 20 and moving it to the auxiliary mounting platform 40 for assembly with the anti-bird thorn mounting plate 10;

[0082] The receiving rods 56 on both sides perform the manufacturing work of the bird-proof V-shaped wire alternately. When the splint 65 grabs the bird-proof V-shaped wire processed on one side, the receiving rod 56 on the other side takes over the newly made bird-proof V-shaped wire. The processing of the bird-proof V-shaped wire is completed by alternating work in this way.

[0083] The auxiliary mounting platform 40 includes a positioning platform 70 installed on the rear side of the second support frame 37. The positioning platform 70 is provided with a mounting notch. A plurality of guide bars 71 are symmetrically arranged on both sides of the mounting notch. The guide bars 71 are provided with avoidance grooves 71a. The guide bars 71 correspond to the plug-in positions of the bird-proof V-shaped wires 20. The avoidance grooves 71a on the guide bars 71 cooperate with each other to form guide holes for facilitating the passage of the steel wire. The guide bars 71 on both sides open and close under the control of the operating cylinder. The positioning platform 70 is located above the placement bar 11.

[0084] After the straight wire is installed, the bird-proof thorn is transported to the bottom of the positioning platform 70. After the placement bar 11 is fixed, the working arm 39 grabs the bird-proof thorn V-shaped wire 20 and moves it to the top of the guide bar 71, and controls the extension arm 39b to move downward to insert the grabbed V-shaped wire into the bird-proof thorn mounting plate. After the V-shaped wire is plugged into the bird-proof thorn mounting plate, the guide bar 71 opens, thereby preventing the guide bar from obstructing the installation of the V-shaped wire. At the same time, the ninth cylinder 67 works and controls the pressing rod 69 to move downward. The pressing rod 69 will push the angle of the V-shaped wire downward and firmly insert it into the bird-proof thorn mounting plate. After the bird-proof thorn V-shaped wire is assembled, the bird-proof thorn equipped with the straight wire and the V-shaped wire moves toward the bird-proof thorn V-shaped wire secondary processing part 4.

[0085] The bird-thorn-proof V-shaped wire secondary processing unit 4 includes a lifting plate 72 provided on the frame 8. The lifting plate 72 is driven up and down by the tenth cylinder 73. A processing base 74 is provided on the top of the lifting plate 72. Processing vertical rods 75 are symmetrically provided on the front and rear sides of the top of the processing base 74.

A crossbeam is provided on the front side of the second support frame 37. A retaining pressure block 77 that can move up and down is provided on the crossbeam. The retaining pressure block 77 is located directly above the processing base 74.

[0086] The processing vertical rods 75 include long vertical rods 75a and short vertical rods 75b, and the long vertical rods 75a and the short vertical rods 75b are arranged alternately with each other;

[0087] A base plate 76 is provided on the crossbeam, and an eleventh air cylinder 78 is provided at the lower end of the base plate 76 . The retaining pressure block 77 moves up and down under the drive of the eleventh air cylinder 78 .

[0088] The bird-proof spikes with V-shaped wire installed are transported to the top of the processing base 74. At this time, the eleventh cylinder 78 starts to control the retaining pressure block 77 to move downward and press on the bird-proof spikes on the placement strip 11. At this time, the straight wire and the V-shaped wire of the bird-proof spikes are all facing downward. Then the processing base 74 moves upward under the drive of the cylinder, thereby pushing the processing vertical rod 75 into the avoidance groove 11a of the placement strip 11. Subsequently, the processing vertical rod 75 will push the two end rods of the bird-proof V-shaped wire to open, thereby expanding the opening angle of the bird-proof V-shaped wire. According to the different lengths of the long vertical rod 75a and the short vertical rod 75b, the opening angle of the bird-proof V-shaped wire will be different. The long vertical rod 75a has to move upward a farther distance than the short vertical rod 75b, so the long vertical rod 75a will make the bird-proof V-shaped wire open at a larger angle, while the short vertical rod 75b will make the bird-proof V-shaped wire open at a smaller angle, so that the production requirements of the bird-proof V-shaped wire with different opening angles can be met. After the secondary processing of the V-shaped wire is completed, the bird-proof thorn is transported as a whole to the unloading mechanism 5.

[0094] When the grabbing head moves toward the position of the placement strip 11, the plug connector 86 will be inserted into the plug port 18c. At this time, after entering the plug port 18c, the plug connector 86 will press against the limit plate 18b and shrink into the mounting block 18a. At this time, the bird-proof spike is released from the restriction and can be removed from the placement strip 11.

[0095] A finished product conveyor belt 6 is provided on the frame 8 at a position below the corresponding grabbing head.

[0096] After the bird-proof thorn is assembled, it will move to the unloading mechanism. At this time, the twelfth cylinder 80 works, causing the grabbing head to move to one side of the bird-proof thorn, and the plug connector 86 is plugged into the positioning clamp 18 to open it. Then the finger cylinder 83 works to control the grabbing rods 82 on both sides to be clamped on the bird-proof thorn mounting plate. Then the piston rod of the twelfth cylinder 80 is recovered, thereby removing the assembled bird-proof thorn from the placement strip 11. After removal, the finger cylinder 83 controls the grabbing rods 82 on both sides to open. At the same time, the unloading cylinder 84 also works, and its piston rod continuously extends and retracts, thereby causing the unloading head 85 to fall off at the grabbing rod 82 and fall onto the finished product conveyor belt 6 for transportation.

As the conveying chain 9 rotates intermittently, the feeding mechanism 7 will continuously place the anti-bird thorn installation plate 10 on the placement bar 11. As the conveying chain 9 is conveyed, the anti-bird thorn installation plate is first conveyed to the anti-bird thorn straight wire cutting installation part 2. At this time, the positioning seat works to fix the position of the placement bar 11, and then the mechanism there cuts the conveyed steel wire, and the cut steel wire is installed in the anti-bird thorn installation plate to form the anti-bird thorn straight wire 19. Then the positioning seat is retracted, and the conveying chain 9 continues to rotate and conveys the anti-bird thorn equipped with straight wire to the anti-bird thorn V-shaped wire cutting installation part 3, the positioning seat therein fixes the placement strip 11, and then the mechanism therein starts to work, and the second cutters 50 on both sides intermittently cut the steel wire conveyed, and make the cut steel wire into bird-proof V-shaped wire after extrusion, and then the working arm starts to work, which grabs the formed V-shaped wire and inserts it into the bird-proof thorn installation plate 10.
