Description

Technical Field

[0001] The present invention relates to an automatic placement mechanism, in particular to an automatic placement mechanism for integrally formed coils. Background Art

[0002] In the electronic field, the wound coils are randomly placed in the turnover boxes, which not only easily causes product deformation, but also makes it impossible to achieve automated production in the next process.

[0003] In order to solve the above technical problems, a carrying fixture appears. The products produced in the previous process and the equipment in the subsequent process are turned over through this carrying fixture to achieve automated production. There is no need for manual sorting and transition in the middle, which can not only improve the product quality, but also reduce the labor cost and improve the production efficiency.

[0004] And this carrying fixture is also a fork fixture, which realizes the neat placement of products through fixed support rods. Specifically, it is composed of a bottom plate and four positioning columns fixed on the bottom plate. The wound coils are sequentially inserted into the four positioning columns of the fork fixture through the wire threading mechanism of the winding machine. However, such a carrying fixture not only occupies a large area, but also is not easy to stack and pile up. Therefore, manual feeding and conveying are still required each time to ensure the timely supply of the carrying fixture. Summary of the Invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide an automatic placement mechanism for integrally formed coils, which is used to stack and place the carrying fixtures to reduce the floor area of the carrying fixtures, and can automatically convey the carrying fixtures to the insertion station of the integrally formed coils, so that the wire threading mechanism of the winding machine can sequentially insert the coils into the carrying fixtures. There is no need for manual continuous transition and conveying in the middle, so as to further reduce the labor cost and improve the production efficiency.

[0006] The present invention provides the following technical solutions:

[0007] An automatic placement mechanism for integrally formed coils includes a carrying fixture for stacking and placing integrally formed coils, a stacking mechanism for stacking and placing the carrying fixtures before the coil insertion process, and a conveying mechanism for receiving the materials discharged from the stacking mechanism. After receiving the carrying fixture discharged from the stacking mechanism, the conveying mechanism is used to convey it to the insertion station of the integrally formed coils, so that the wire threading mechanism of the winding machine can sequentially insert the coils into the carrying fixtures. The wire threading mechanism of the winding machine is a prior art and will not be described in detail here;

[0008] The carrier jig includes a bottom plate, a cushion block and four positioning columns. The cushion blocks are provided in four groups and are distributed in a rectangular shape around the bottom plate, so that when the carrier jig is stacked, a stacking gap is formed between the two groups of bottom plates under the action of the cushion blocks. This stacking gap, when used in the stacking mechanism, can facilitate the layered unloading of the carrier jig. The bottom plate is also provided with four positioning columns for the coils to be sequentially sleeved and inserted. The bottom ends of the positioning columns are installed in the bottom plate through a rotating block.

[0009] When the carrying jigs are stacked and placed in the stacking mechanism, the positioning column rotates to be horizontal with the bottom plate, and when the carrying jigs are unloaded onto the conveying mechanism, the positioning column rotates to be vertical with the bottom plate. Four groups of horizontal grooves are also provided on the bottom plate. The four groups of horizontal grooves correspond to the side of the positioning column close to the edge of the bottom plate. When the positioning column rotates from being vertical to being horizontal with the bottom plate, the horizontal groove is used to accommodate the positioning column rotated to be horizontal with the bottom plate.

[0010] At this point, the stacking mechanism stacks the stacked carrying jigs, and the four groups of positioning columns are rotated to be level with the base plate, which can reduce the stacking area. When the carrying jig is unloaded to the conveying mechanism, the positioning columns are driven to rotate to be perpendicular to the base plate. The conveying mechanism can convey the carrying jig to the one-piece formed coil insertion station, so that the winding machine insertion mechanism can insert the coil into the carrying jig in turn. There is no need for manual continuous transition transportation in the middle, which can further reduce labor costs and improve production efficiency.

[0011] Preferably, a group of plug-in columns are also passed through the center of the positioning column, and a group of plug-in holes for plugging and docking with the plug-in columns are also opened on the base plate. When the positioning column is rotated from horizontal to vertical with the base plate, the plug-in column is aligned with the plug-in hole, and under the action of gravity of the plug-in column, the plug-in column passes through the bottom end of the positioning column and is inserted into the plug-in hole. At this point, when the positioning column is rotated to be vertical with the base plate, vertical positioning can also be achieved at the same time, so as to avoid the positioning column from rotating again during later transportation, affecting the working state of the carrying jig when it is transported to the insertion station.

[0012] Preferably, the stacking mechanism comprises a left side plate, a right side plate, a support plate 1, a support plate 2, a support plate 3 and a driving rod, wherein a material storage gap is provided between the left side plate and the right side plate for vertical descent of a load-bearing jig for stacking, and two groups of support plates 1, 2 and 3 are respectively provided, and are arranged on the left side plate and the right side plate in a counter-positioned manner, two groups of support plates 1 and two groups of support plates 2 are arranged in the middle of the left side plate and the right side plate, and two groups of support plates 3 are distributed at the bottom of the left side plate and the right side plate, and the support plate 2 is used to support below the bottom-layer load-bearing jig of stacking under the drive of the driving cylinder 2, and the support plate 1 is located above the support plate 2, and is used to be spaced in the stacking gap above the bottom-layer load-bearing jig under the drive of the driving cylinder 1;

[0013] When the bottommost layer of the palletizing carrier fixture needs to be unloaded, the second support plate retracts from the material receiving gap under the drive of the driving cylinder two, and the bottommost layer of the palletizing carrier fixture freely unloads. Then, the second support plate extends into the material receiving gap again under the drive of the driving cylinder two, and the first support plate retracts from the material receiving gap under the drive of the driving cylinder one. The carrier fixtures stacked between the left side plate and the right side plate synchronously descend until the bottommost carrier fixture is supported on the second support plate again;

[0014] The third support plate extends into the material receiving gap under the drive of the driving cylinder three to support the carrier fixture that freely falls off the second support plate. And there are two groups of driving rods, and both ends are horizontally slidably installed in the left side plate and the right side plate. It is used to drive the positioning column to rotate perpendicular to the bottom plate when the carrier fixture falls onto the third support plate;

[0015] So far, the upper part of the material receiving gap between the left side plate and the right side plate is used to realize the palletizing of the carrier fixtures, and can perform automatic sequential unloading operations under the action of the first support plate and the second support plate. And the unloaded carrier fixture can, when falling onto the third support plate, realize the automatic rotation operation of the positioning column driven by the driving rod. Until the positioning column rotates perpendicular to the bottom plate, when the third support plate retracts from the material receiving gap, the carrier fixture can automatically fall onto the conveying mechanism. The overall structure is simple, and the automatic operation is more convenient.

[0016] Preferably, a set of side guiding plates are respectively arranged on both sides of the left side plate and the right side plate. The side guiding plates extend from the top of the left side plate or the right side plate to above the driving rod. The side guiding plates are used to cooperate with the left side plate or the right side plate to guide and limit the stacked carrier fixtures.

[0017] Preferably, the two groups of driving rods are distributed in pairs on both sides of the left side plate and the right side plate. A set of lead screws are respectively installed on the left side plate and the right side plate. Both ends of the driving rod are screwed and installed on the two groups of lead screws. When the two groups of lead screws rotate synchronously under the drive of their respective lead screw motors, the two groups of driving rods move towards or away from each other under the drive of the lead screws;

[0018] When the carrier fixture falls between the second support plate and the third support plate, the two groups of driving rods move away from each other under the drive of the lead screws to both sides of the left side plate and the right side plate, so that they will not block the bottom plate of the carrier fixture, but will cause an obstruction to the positioning column. When the two groups of driving rods move towards each other again under the drive of the lead screws, the driving rods drive the positioning column to rotate until it is perpendicular to the bottom plate for positioning. So far, the automatic forming of the working state of the carrier fixture can be completed.

[0019] Preferably, the conveying mechanism is located below the material receiving gap, and a set of ejecting mechanism is also arranged between it and the material receiving gap. The ejecting mechanism is used to transfer the carrier fixture that detaches from the third support plate to the conveying mechanism to prevent the carrier fixture from tilting during the falling process.

[0020] Preferably, the conveying mechanism adopts a roller conveyor, and the lifting mechanism includes multiple groups of lifting plates and horizontal plates for installing the lifting plates. The horizontal plates rise under the drive of the bottom lifting cylinder to support the bearing jig separated from the support plate three. When the horizontal plate supports the bearing jig to descend to be flush with the roller conveyor, the bearing jig moves toward the entry station of the one-piece formed coil under the drive of the roller conveyor.

[0021] Preferably, at the insertion station of the one-piece formed coil, baffles for positioning the carrying jig are further provided on both sides of the conveying mechanism. The baffles are extended to the top of the conveying mechanism under the drive of the baffle cylinder and are limited at the front end of the bottom plate of the carrying jig to position the carrying jig. After the winding machine material insertion mechanism inserts the coil into the carrying jig in turn, the baffles can be withdrawn from the top of the conveying mechanism under the drive of the baffle cylinder, and the carrying jig can continue to move to carry out the next round of the carrying jig cycle.

[0022] The beneficial effects of the present invention are:

[0023] In the present invention, when the stacking mechanism stacks the stacked load-bearing jigs, the four groups of positioning columns rotate to be level with the bottom plate, which can reduce the stacking area. When the load-bearing jigs are unloaded to the conveying mechanism, the positioning columns are driven to rotate to be perpendicular to the bottom plate. The setting of the plug-in columns can ensure that when the positioning columns rotate to be perpendicular to the bottom plate, vertical positioning can also be achieved, so as to avoid the positioning columns from rotating again during the later transportation, which will affect the working state of the load-bearing jig when it is conveyed to the entry station.

[0024] In the present invention, the stacking mechanism occupies a small area and can also realize automatic unloading to the conveying mechanism. The conveying mechanism can convey the supporting fixture to the one-piece formed coil insertion station, so that the winding machine feeding mechanism can insert the coil into the supporting fixture in turn. There is no need for manual continuous transition transportation in the middle, so as to further reduce labor costs and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] like Figure 1-6 As shown, an automatic placement mechanism for an integrally formed coil, in this embodiment, includes a carrier jig 1 for stacking and placing the integrally formed coil, a stacking mechanism 2 for stacking and placing the carrier jig 1 before the coil insertion process, and a conveying mechanism 3 for receiving the material discharged by the stacking mechanism 2. After receiving the carrier jig 1 discharged by the stacking mechanism 2, the conveying mechanism 3 is used to convey it to the insertion station of the integrally formed coil, so that the winding machine material feeding mechanism can sequentially insert the coil into the carrier jig 1. The winding machine material feeding mechanism is a prior art and will not be described in detail here.

[0036] The carrier jig 1 includes a bottom plate 11, a cushion block 12 and four positioning columns 13. The cushion blocks 12 are provided in four groups and are distributed in a rectangular shape around the bottom plate 11, so that when the carrier jig 1 is stacked, a stacking gap is formed between two groups of bottom plates 11 under the action of the cushion blocks 12. This stacking gap, when used in the stacking mechanism 2, can facilitate the layered unloading of the carrier jig 1. The bottom plate 11 is also provided with four positioning columns 13 for the coils to be sequentially sleeved and inserted. The bottom ends of the positioning columns 13 are installed in the bottom plate 11 through the rotating block 14;

[0037] When the carrier fixture 1 is stacked and placed in the stacking mechanism 2, the positioning posts 13 rotate to be horizontal with the bottom plate 11. When the carrier fixture 1 is unloaded onto the conveying mechanism 3, the positioning posts 13 rotate to be perpendicular to the bottom plate 11. Four groups of horizontal grooves 15 are also provided on the bottom plate 11. The four groups of horizontal grooves 15 are correspondingly located on one side of the positioning posts 13 close to the edge of the bottom plate 11. When the positioning posts 13 rotate from being perpendicular to the bottom plate 11 to being horizontal with the bottom plate 11, the horizontal grooves 15 are used to accommodate the positioning posts 13 that rotate to be horizontal with the bottom plate 11.

[0038] So far, when the stacking mechanism 2 stacks and places the carrier fixtures 1, the four groups of positioning posts 13 rotate to be horizontal with the bottom plate 11, which can reduce the floor area of stacking. When unloading the carrier fixture 1 onto the conveying mechanism 3, the positioning posts 13 are driven to rotate to be perpendicular to the bottom plate 11. The conveying mechanism 3 can then convey this carrier fixture 1 to the threading station of the one-piece formed coil, so that the coil threading mechanism of the winding machine can thread the coils into the carrier fixture 1 in sequence, without the need for manual continuous transfer in the middle, further reducing labor costs and improving production efficiency.

[0039] The stacking mechanism 2 includes a left side plate 21, a right side plate 22, a first support plate 23, a second support plate 24, a third support plate 25, and a driving rod 26. There is a material accommodating gap between the left side plate 21 and the right side plate 22 for the vertically descending stacked carrier fixtures 1. There are two groups of each of the first support plate 23, the second support plate 24, and the third support plate 25, and they are distributed in a pairwise alignment on the left side plate 21 and the right side plate 22. The two groups of the first support plate 23 and the two groups of the second support plate 24 are arranged in the middle of the left side plate 21 and the right side plate 22, while the two groups of the third support plate 25 are distributed at the bottom of the left side plate 21 and the right side plate 22. The second support plate 24 is used to support under the bottommost stacked carrier fixture 1 under the drive of the second driving cylinder. The first support plate 23 is located above the second support plate 24 and is used to be spaced in the stacking gap above the bottommost stacked carrier fixture 1 under the drive of the first driving cylinder.

[0040] When the bottommost stacked carrier fixture 1 needs to be unloaded, the second support plate 24 withdraws from the material accommodating gap under the drive of the second driving cylinder, and the bottommost stacked carrier fixture 1 freely drops. The second support plate 24 then extends into the material accommodating gap again under the drive of the second driving cylinder. Then the first support plate 23 withdraws from the material accommodating gap under the drive of the first driving cylinder, and the stacked carrier fixtures 1 between the left side plate 21 and the right side plate 22 drop synchronously until the bottommost carrier fixture 1 is supported on the second support plate 24 again.

[0041] The third support plate 25 extends into the material accommodating gap under the drive of the third driving cylinder to support the carrier fixture 1 that freely falls off the second support plate 24. There are two groups of the driving rods 26, and both ends are horizontally slidably installed in the left side plate 21 and the right side plate 22. They are used to drive the positioning posts 13 to rotate to be perpendicular to the bottom plate 11 when the carrier fixture 1 falls onto the third support plate 25.

[0042] So far, the upper part of the material-containing gap between the left plate 21 and the right plate 22 is used to realize the stacking of the loading fixture 1, and can perform an automatic sequential blanking operation under the action of the first support plate 23 and the second support plate 24. After blanking, when the loading fixture 1 falls onto the third support plate 25, the driving rod 26 drives to realize the automatic rotation operation of the positioning column 13 until the positioning column 13 rotates to be perpendicular to the bottom plate 11. Then, when the third support plate 25 exits the material-containing gap, the loading fixture 1 automatically falls onto the conveying mechanism 3. The overall structure is simple, and the automatic operation is more convenient.

[0043] On both sides of the left plate 21 and the right plate 22, a set of side guiding plates 27 are respectively arranged. The side guiding plates 27 extend from the top of the left plate 21 or the right plate 22 to above the driving rod 26. The side guiding plates 27 are used to cooperate with the left plate 21 or the right plate 22 to guide and limit the stacked loading fixture 1.

[0044] The two groups of driving rods 26 are distributed in pairs on both sides of the left plate 21 and the right plate 22. On the left plate 21 and the right plate 22, a set of lead screws 28 are respectively installed. The two ends of the driving rod 26 are screwed and installed on the two groups of lead screws 28. When the two groups of lead screws 28 rotate synchronously under the drive of their respective lead screw motors, the two groups of driving rods 26 move towards or away from each other under the drive of the lead screws 28;

[0045] When the loading fixture 1 falls between the second support plate 24 and the third support plate 25, the two groups of driving rods 26 move away from each other under the drive of the lead screws 28 to both sides of the left plate 21 and the right plate 22, so as not to block the bottom plate 11 of the loading fixture 1, but will cause an obstruction to the positioning column 13. When the two groups of driving rods 26 move towards each other under the drive of the lead screws 28, the driving rod 26 drives the positioning column 13 to rotate until it is perpendicular to the bottom plate 11 for positioning. So far, the automatic forming of the working state of the loading fixture 1 can be completed.

[0046] The conveying mechanism 3 is located below the material-containing gap, and a set of ejecting mechanisms 31 are also arranged between it and the material-containing gap. The ejecting mechanisms 31 are used to transfer the loading fixture 1 that has separated from the third support plate 25 to the conveying mechanism 3 to prevent the loading fixture 1 from tilting during the falling process.

[0047] The conveying mechanism 3 adopts a roller conveyor, and the ejecting mechanism 31 includes multiple sets of top plates 311 and a horizontal plate 312 for installing the top plates 311. The horizontal plate 312 rises under the drive of the bottom lifting cylinder to support the loading fixture 1 that has separated from the third support plate 25. When the horizontal plate 312 supports the loading fixture and descends to be flush with the roller conveyor, the loading fixture 1 moves towards the insertion station of the integral forming coil under the drive of the roller conveyor.

[0048] At the insertion station of the one-piece formed coil, baffles 32 for positioning the carrier jig 1 are also provided on both sides of the conveying mechanism 3. The baffles 32 are extended to the top of the conveying mechanism 3 under the drive of the baffle cylinder, and are limited at the front end of the bottom plate 11 of the carrier jig 1, so as to position the carrier jig 1. After the winding machine material feeding mechanism inserts the coil into the carrier jig 1 in turn, the baffles 32 can be driven by the baffle cylinder to withdraw from the top of the conveying mechanism 3, and the carrier jig 1 can continue to move to carry out the next round of the carrier jig 1 cycle.

[0049] Example 2

[0050] An automatic placement mechanism for an integrally formed coil is disclosed in the present embodiment, which is further limited on the basis of the embodiment 1, wherein a group of plug-in posts 16 are further penetrated through the center of the positioning post 13, and a group of plug-in holes 17 for plugging and docking with the plug-in posts 16 are further opened on the bottom plate 11. When the positioning post 13 is rotated from being horizontal to the bottom plate 11 to being vertical to the bottom plate 11, the plug-in posts 16 are aligned with the plug-in holes, and under the action of the gravity of the plug-in posts 16, the plug-in posts 16 pass through the bottom end of the positioning post 13 and are inserted into the plug-in holes. At this point, when the positioning post 13 is rotated to be vertical to the bottom plate 11, vertical positioning can also be achieved at the same time, so as to avoid the positioning post 13 from rotating again during the later transportation, which affects the working state of the carrying fixture 1 when it is transported to the insertion station.

[0051] The working principle of the present invention is:

[0052] In the present invention, when the stacking mechanism 2 stacks the stacked carrying jigs 1, the four groups of positioning columns 13 rotate to be level with the bottom plate 11, which can reduce the stacking area. When the carrying jig 1 is unloaded to the conveying mechanism 3, the positioning columns 13 are driven to rotate to be perpendicular to the bottom plate 11. The setting of the plug-in column 16 can ensure that when the positioning column 13 rotates to be perpendicular to the bottom plate 11, vertical positioning can also be achieved, so as to avoid the positioning column 13 from rotating again during the later transportation, which affects the working state of the carrying jig 1 when it is conveyed to the entry station.

[0053] In the present invention, the stacking mechanism 2 occupies a small area for stacking, and can also realize automatic unloading to the conveying mechanism 3, and the conveying mechanism 3 can convey the carrier jig 1 to the insertion station of the integrally formed coil, so that the winding machine material feeding mechanism can sequentially insert the coil into the carrier jig 1, and there is no need for manual continuous transitional conveying in the middle, so as to further reduce labor costs and improve production efficiency;

[0054] In the stacking mechanism 2, the upper part of the material receiving gap between the left side plate 21 and the right side plate 22 is used to stack the loading fixtures 1, and can perform an automated sequential blanking operation under the action of the first support plate 23 and the second support plate 24. After blanking, when the loading fixture 1 falls onto the third support plate 25, the driving rod 26 drives it to perform an automated rotation operation of the positioning column 13 until the positioning column 13 rotates to be perpendicular to the bottom plate 11. Then, when the third support plate 25 exits the material receiving gap, the loading fixture 1 automatically falls onto the conveying mechanism 3. The overall structure is simple and the automated operation is more convenient;

[0055] When the loading fixture 1 falls between the second support plate 24 and the third support plate 25, the two groups of driving rods 26 move away from each other to both sides of the left side plate 21 and the right side plate 22 under the drive of the lead screw 28, so as not to block the bottom plate 11 of the loading fixture 1, but will cause an obstruction to the positioning column 13. When the two groups of driving rods 26 move towards each other again under the drive of the lead screw 28, the driving rod 26 drives the positioning column 13 to rotate until it is perpendicular to the bottom plate 11 for positioning. Thus, the automated formation of the working state of the loading fixture 1 can be completed.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
