Technical Field

[0001] The invention belongs to the technical field of motor production lines, and in particular relates to a card issuing layered collection device, an automatic wire inserting system and a method. Background Art

[0002] As the use of motor flat wire stators increases, manufacturers have higher requirements for production efficiency and product qualification. Manual wire insertion can no longer meet the needs of actual production. It is inefficient and has a high error rate, which affects the stability of product quality. Automatic wire insertion is difficult to insert the hairpin directly into the stator, and an intermediate mold is required for transition. Because it needs to be compatible with the production of all hairpins, the production and debugging of the hairpin machine is difficult. Summary of the invention

[0003] In order to solve the problems in the background technology, the present invention proposes a card issuing layer collection device, an automatic wire insertion system and a method.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A card issuing layered collection device, comprising a conveying line, a tray mechanism and a tensioning mechanism;

[0006] The tray mechanism is provided with a guide tool, a cavity tool and a tray;

[0007] The pallet is located on the conveying path of the conveyor line; the cavity tooling is installed on the surface of the pallet, and a plurality of grooves are evenly arranged on the inner surface of the cavity tooling along the circumference; the guide tooling is connected to the end of the cavity tooling away from the pallet, and a guide groove corresponding to the grooves is opened on the surface;

[0008] The tensioning mechanism is arranged along the conveying path of the conveying line, and comprises a track groove barrel, the outer surface of which is provided with track grooves corresponding to the grooves one by one, and a compression piece movable in the radial direction is installed in each track groove;

[0009] When the tray mechanism moves along the conveyor line to the position corresponding to the tensioning mechanism, the track groove barrel slides with the cavity tooling along the axial direction, and the pressing plate moves radially toward or away from the groove.

[0010] Furthermore, the tensioning mechanism is located below the conveying path of the conveying line.

[0011] Furthermore, in the tensioning mechanism:

[0012] The top of the track tank is equipped with a cover plate of equal diameter, and the bottom is equipped with a fixing seat of equal diameter;

[0013] The outer diameter of the track tank is smaller than the inner diameter of the cavity tooling.

[0014] Furthermore, the tensioning mechanism also includes a frame, a lifting cylinder, a connecting piece and a slide module;

[0015] The lifting cylinder is fixed on the frame, and one end is connected to a connecting piece;

[0016] One end of the connecting piece away from the lifting cylinder is connected to the transfer surface of the transfer seat;

[0017] The slide module is mounted on the mounting surface of the adapter and is used to support and drive the pressing plate to move radially.

[0018] Further, in the slide module, the upper mounting surface of the adapter is connected to a plurality of equal-height blocks, and the lower mounting surface is mounted with a telescopic cylinder;

[0019] A positioning plate is installed on the top of the equal height block, and the positioning plate is connected to the fixing seat.

[0020] Further, in the slide module, the piston rod of the telescopic cylinder is connected to a driving rod, and the driving rod passes through a fixing seat and enters into the track groove barrel;

[0021] The end of the driving rod away from the piston rod is provided with an integrally connected driving ring, the driving ring is trumpet-shaped, with the driving rod as the starting point, and the diameter increases linearly along the axial direction of the driving rod;

[0022] An oblique opening groove which is slidably matched with the driving ring is provided on the pressing plate, and the oblique opening groove is arranged to be inclined relative to the axial direction of the track groove barrel.

[0023] An automatic wire insertion system, in the above-mentioned card issuing and layering collection device, a plurality of tensioning mechanisms are arranged along the water conveying direction of the conveying line;

[0024] Furthermore, a plurality of card issuing machines corresponding to each tensioning mechanism are arranged on one side of the conveying line.

[0025] An automatic wire insertion method, applied to the above-mentioned automatic wire insertion system, comprises the following steps:

[0026] The pallet conveying mechanism is conveyed through the conveyor line;

[0027] At the position of the tensioning mechanism corresponding to the conveyor line, lift the track tank to the pallet mechanism;

[0028] Compress the hairpins of the i-1th layer radially by a compression sheet, i>1;

[0029] Insert the card into the tray mechanism through the card issuing machine.

[0030] Further, the hairpins of the i-1th layer are compressed radially by the compression sheet, comprising the following steps:

[0031] Apply radial pressure to the compression plate through the tensioning mechanism;

[0032] The pressing sheet is moved toward the i-1th layer of hairpins in the groove by radial pressure, and the i-1th layer of hairpins is squeezed.

[0033] Furthermore, inserting the card into the tray mechanism through the card issuing machine includes the following steps:

[0034] Insert the i-th layer of hairpins into the grooves of the cavity tooling along the guide grooves.

[0035] Beneficial effects of the present invention:

[0036] 1. The card-laying collection device of the present invention places a tray mechanism on the conveyor line and is equipped with a corresponding tensioning mechanism. The compression sheet in the tensioning mechanism applies radial pressure to compress the card-laying of the previous layer, thereby providing sufficient space for the installation of the card-laying of the current layer, thereby improving efficiency and stabilizing product quality.

[0037] 2. The automatic wire insertion system of the present invention is provided with multiple tensioning mechanisms and corresponding card issuing machines on the conveyor line. When the tray mechanism moves to each tensioning mechanism along the conveyor line, each tensioning mechanism can squeeze each layer of card issuing, providing space for the subsequent installation of multiple layers of card issuing; at the same time, the card issuing machine is separated and located on one side of the conveyor line, and can produce different single-layer card issuing coils and install them into the tray mechanism through the corresponding tensioning mechanism. The card issuing machine only needs to produce one type of card issuing at the minimum, which reduces the difficulty of production and debugging of the card issuing machine;

[0038] 3. The automatic wire insertion method of the present invention adopts an automatic tightening mechanism. Before the current layer of hairpins are inserted into the middle mold, the previously inserted hairpins are automatically pressed. After all the hairpins are inserted, the tightening mechanism can press all the hairpins to ensure the overall size, which is convenient for the subsequent hairpins to be inserted into the stator.

[0039] Other features and advantages of the present invention will be described in the following description, and partly become obvious from the description, or be understood by implementing the present invention.

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The present invention provides a card-issuing layered collection device, such as Figure 1As shown, it includes a conveyor line 1, a tray mechanism 2 and a tensioning mechanism 3. The conveyor line 1 can convey the tray structure to ensure that the device can be stably circulated. The tray mechanism 2 is provided with a profiling mold, which can insert the looped hairpins into it at a specific position. The tensioning mechanism 3 is installed below the conveyor line 1, and it can compress and loosen the hairpins by the expansion and contraction of the compression sheet 309, so that there is enough insertion space for the subsequent inserted hairpins.

[0054] The following is combined with Figure 2-4 ,right Figure 1 The structure is further described.

[0055] like Figure 2 As shown, the tray mechanism 2 is provided with a guide fixture 201, a cavity fixture 202 and a tray 203. The tray 203 is in direct contact with the conveyor line 1 and is located on the conveying path of the conveyor line 1; the cavity fixture 202 is fixed on the upper surface of the tray 203, and the inner surface of the cavity fixture 202 is evenly provided with a plurality of grooves 2021 along the circumferential direction to facilitate the placement of the hairpin legs. The guide fixture 201 is connected to the end of the cavity fixture 202 away from the tray 203, and a guide groove 2011 corresponding to the groove 2021 is opened on the surface.

[0056] It should be noted that Figure 2 The tray mechanism 2 needs to be combined Figure 3 The tensioning mechanism 3 is used synchronously to improve the integration efficiency of the motor card issuance.

[0057] like Figure 3 As shown, the tensioning mechanism 3 mainly includes a frame 301, a lifting cylinder 302, a connecting piece 303, a slide module and an adapter 304. The frame 301 can be placed on the floor of the workshop as a supporting device for the tensioning mechanism 3; the lifting cylinder 302 is fixedly mounted on the frame 301, and its piston rod is arranged upward and connected to the connecting piece 303. The connecting piece 303 is arranged in the horizontal direction, and its end away from the lifting cylinder 302 is fixedly connected to the transfer surface of the adapter 304. The adapter 304 is an L-shaped seat, and a reinforcing rib plate is welded at a right angle. In addition, the mounting surface of the adapter 304 perpendicular to the transfer surface is used to install the slide module.

[0058] It should be noted that, in the above structure, the lifting cylinder 302 can raise the horizontal height of the slide module so that the slide module can meet the station requirements of the motor card installation.

[0059] Further, in Figure 3In the figure, the tensioning mechanism 3 is arranged along the conveying path of the conveyor line 1, including a track groove barrel 308, and the outer surface of the track groove barrel 308 is provided with track grooves corresponding to the grooves 2021, and a radially movable clamping plate 309 is installed in each track groove. When the tray mechanism 2 moves along the conveyor line 1 to the position corresponding to the tensioning mechanism 3, the track groove barrel 308 slides with the cavity tooling 202 along the axial direction, and the clamping plate 309 moves radially toward or away from the groove 2021.

[0060] It should be noted that, in the tensioning mechanism 3, the pressing sheet 309 can squeeze the hairpins in the groove 2021 under the action of radial pressure, and finally compress all the hairpins to ensure the overall size, so as to facilitate the subsequent insertion of the hairpins into the stator.

[0061] In addition, a cover plate 3013 of equal diameter is installed at the top of the track trough barrel 308, and a fixing seat 3010 of equal diameter is installed at the bottom. The outer diameter of the track trough barrel 308 is smaller than the inner diameter of the cavity tooling 202, so that relative sliding can be achieved between the track trough barrel 308 and the cavity tooling 202 to avoid interference between the two.

[0062] Further, in Figure 3 In the slide module, the upper mounting surface of the adapter 304 is connected with a plurality of equal height blocks 306, and the lower mounting surface is installed with a telescopic cylinder 305. The top of the equal height block 306 is installed with a positioning plate 307, and the positioning plate 307 is connected to the fixed seat 3010.

[0063] like Figure 4 As shown, the piston rod of the telescopic cylinder 305 is connected to a driving rod 3011, and the driving rod 3011 passes through the fixing seat 3010 and enters the track groove barrel 308. The end of the driving rod 3011 away from the piston rod is provided with an integrally connected driving ring 3012, and the driving ring 3012 is trumpet-shaped, starting from the driving rod 3011, and the diameter increases linearly along the axial direction of the driving rod 3011. In addition, an oblique opening groove 3091 is provided on the pressing plate 309 to slide with the driving ring 3012, and the oblique opening groove 3091 is arranged to be inclined relative to the axial direction of the track groove barrel 308.

[0064] It should be noted that in the above structure, when the piston rod of the telescopic cylinder 305 is extended, the drive rod 3011 and the drive ring 3012 will move toward the side of the cover plate 3013. At this time, the drive ring 3012 will move along the inclined opening groove 3091, so that the clamping plate 309 moves radially toward the center of the track groove barrel 308; when the piston rod of the telescopic cylinder 305 is retracted, the drive ring 3012 will gradually move away from the cover plate 3013. At this time, the clamping plate 309 will move radially outward, thereby squeezing the hairpin in the groove 2021.

[0065] like Figure 5 As shown, it is an automatic plug-in system, which applies Figure 1-Figure 4 A hairpin layered collection device.

[0066] Specifically, the system is provided with a plurality of tensioning mechanisms 3 along the conveying direction of the conveyor line 1, and a plurality of card issuing machines 4 corresponding to each tensioning mechanism 3 are provided on one side of the conveyor line 1. The number of the card issuing machines 4 corresponds to the tensioning mechanism 3 and they are located on one side of the tensioning mechanism 3.

[0067] like Figure 6 As shown, this is an automatic plugging method, which is applied to Figure 5 An automatic wire insertion system comprises the following steps:

[0068] S1: conveying the pallet mechanism 2 through the conveyor line 1.

[0069] S2: At the position of the tensioning mechanism 3 on the conveyor line 1, lift the track tank 308 to the tray mechanism 2.

[0070] S3: Compress the hairpins of the i-1th layer radially by the pressing sheet 309, where i>1.

[0071] S4: Insert the card into the tray mechanism 2 through the card issuing machine 4.

[0072] Furthermore, in S2, the following steps are included:

[0073] S201: The connecting member 303 is driven to move upward by the lifting cylinder 302, and the adapter 304 and the slide module also move accordingly, thereby positioning the track tank 308 in the cavity tooling 202.

[0074] Furthermore, in S3, the following steps are included:

[0075] S301: Positioning the track tank 308 into the corresponding cavity tooling 202 by means of the lifting cylinder 302 .

[0076] S302: The piston rod of the telescopic cylinder 305 is controlled to contract, and the driving ring 3012 gradually moves away from the cover plate 3013. At this time, the clamping plate 309 moves radially outward, and radial pressure can be applied to the clamping plate 309.

[0077] S303: The pressing plate 309 is moved toward the i-1th circle of hairpins in the groove 2021 by radial pressure, and the i-1th circle of hairpins is squeezed.

[0078] It should be noted that when i=1, steps S402 and S403 can be omitted.

[0079] Further, S4 includes the following steps:

[0080] S401: inserting the i-th circle of cards into the groove 2021 along the guide groove 2011 through the card issuing machine 4.

[0081] Combine the following Figure 7-Figure 9 The wiring process is explained by taking a stator with three layers (rings) of card issuance as an example.

[0082] The tray mechanism 2 reaches the working position of the first card issuing machine 4, lifts up and positions the track slot barrel 308, and the card issuing machine 4 transfer mechanism inserts the card issued by this machine into the cavity tooling 202 of the collection tray mechanism 2, completing the insertion of the first layer of card a; then Figure 7 As shown, the tray mechanism 2 is lifted and positioned, and then falls. The tray mechanism 2 reaches the working position of the second card issuing machine 4. The lifting cylinder 302 of the tensioning mechanism 3 lifts the track groove barrel 308 to position, and then the telescopic cylinder 305 extends to press the inserted card a against the side wall of the cavity tooling 202. Then the card issuing machine 4 inserts the neatly arranged card b into the cavity tooling 202 (see Figure 8 ), the telescopic cylinder 305 of the tensioning mechanism 3 is retracted (see Fig. 9 ), the second layer of card insertion is completed; the lifting cylinder 302 retracts, the tray mechanism 2 reaches the working position of the third card issuing machine 4, the lifting cylinder 302 of the tensioning mechanism 3 lifts the track slot barrel 308 to position, and then the clamping telescopic cylinder 305 extends out to press the first two layers of inserted card clips against the side walls of the cavity tooling 202, the card issuing machine 4 inserts the neatly completed card clips into the cavity tooling 202, and the telescopic cylinder 305 of the tensioning mechanism 3 retracts to complete the insertion of the three layers of card clips.

[0083] Finally, the inserted card issuing coil is as follows Fig.10 shown.
