Description

Technical Field

[0001] This invention belongs to the technical field of automated wire processing equipment, specifically relating to a synchronous feeding device with unequal spacing and a feeding method. Background Technology

[0002] In existing wire processing equipment, wire enters the process station for processing via a loading fixture. The synchronous material feeding structures between process stations are equidistantly arranged, but the movement distance from the loading end to the fixture positioning end is inconsistent with the movement distance between process stations. When the fixture is delivered to the loading end, to prevent the fixture from sliding on the conveyor belt and causing wear on the belt surface, thus affecting its service life, a separate material feeding structure is required at the loading end to feed the wire. The feeding action at the loading end and the material feeding action between process stations are sequential, thus increasing the loading and feeding time of the entire equipment, reducing the overall production capacity, and increasing structural costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a synchronous material feeding device and a material feeding method that is compact in structure, simple to operate, highly stable, and capable of synchronously feeding materials between the feeding station and the process station in the wire processing equipment at unequal distances.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A synchronous material feeding device with unequal spacing includes a belt conveyor assembly, a roller transition assembly, and a frame arranged sequentially. The frame is equipped with a fixture slide, a pulley, and a material feeding mechanism with unequal spacing, with the material feeding mechanism located below the fixture slide. Along the wire conveying direction, the fixture slide and the pulley are respectively arranged on opposite sides of the frame. The wire loading fixture, loaded with wire, is conveyed sequentially by the belt conveyor assembly and the roller transition assembly and then enters the frame. One end of the wire loading fixture is slidably connected to the fixture slide, and the other end is slidably connected to the pulley. Under the action of the material feeding mechanism, the wire loading fixture moves and is conveyed on the frame.

[0006] As a further improvement of the present invention, the roller transition assembly is provided with a loading station b, and the frame is provided with a positioning station c, a unloading station e, and multiple equally spaced process stations d. The distance between the loading station b and the positioning station c is less than the distance between the positioning station c and the process station d, and the distance between the positioning station c and the process station d is equal to the distance between adjacent process stations d. The material feeding mechanism is used to move the wire loading fixture from the loading station b to the positioning station c, then from the positioning station c to the process station d, and sequentially move and transfer it among the multiple process stations d, finally moving it to the unloading station e to complete the unloading.

[0007] As a further improvement of the present invention, the feeding mechanism includes: a sliding feeding block unit, a fixed feeding block unit, a driving unit and a guide rail; the guide rail is installed on the frame along the setting direction of the fixture slide, and the frame is provided with a slide groove that cooperates with the guide rail.

[0008] The drive unit is installed on the side of the frame, and the output end of the drive unit is connected to the guide rail;

[0009] The sliding block unit is slidably mounted on the guide rail and slides back and forth along the guide rail. The sliding block unit is used to move the wire loading fixture from the loading station b to the positioning station c.

[0010] Multiple fixed lever units are equally spaced on the guide rail and move back and forth with the guide rail. The fixed lever units are used to move the wire loading fixture from the positioning station c to the process station d, and then move it sequentially between multiple process stations d, finally moving it to the unloading station e to complete the unloading.

[0011] Driven by the drive unit, the guide rail moves back and forth, which in turn drives the sliding block unit and the fixed block unit to move back and forth, so as to realize the wire loading fixture to move and transport on the frame.

[0012] As a further improvement of the present invention, the sliding block unit includes: a first limiting seat, a block mounting seat, a second limiting seat, and a material-pushing block; the first limiting seat and the second limiting seat are both fixedly mounted on the guide rail, and the distance between the first limiting seat and the second limiting seat is equal to the distance between the loading station b and the positioning station c; the block mounting seat is slidably mounted on the guide rail and reciprocates between the first limiting seat and the second limiting seat; the material-pushing block is mounted on the block mounting seat and is used to move the wire loading fixture.

[0013] As a further improvement of the present invention, the fixed lever unit includes lever fixing seats and lever blocks. Multiple lever fixing seats are installed at equal intervals on the guide rail, and lever blocks are installed on lever fixing seats for levering wire loading fixtures. The distance between adjacent lever blocks on lever fixing seats is equal to the distance between adjacent process stations d.

[0014] As a further improvement of the present invention, the distance between the first limiting seat and the second limiting seat is X1, the distance between the second limiting seat and the adjacent pawl fixing seat is X2, and the distance between the adjacent pawl blocks on the pawl fixing seat is X3. The sum of X1 and X2 is equal to X3, so as to realize the synchronous pawl feeding at the feeding station b and the wire loading fixture at the positioning station c or the process station d.

[0015] As a further improvement of the present invention, the drive unit includes a drive component, a lead screw, a coupling, and a connecting plate. The output end of the drive component is connected to the fixed end of the lead screw through the coupling, and the movable end of the lead screw is connected to the guide rail through the connecting plate. Under the drive of the drive component, the lead screw drives the guide rail to reciprocate along the frame, thereby driving the sliding block unit and the fixed block unit to move and move the wire loading fixture.

[0016] As a further improvement of the present invention, the material-pulling block includes a base, a material-pulling block, and an elastic reset member. The bottom of the base is fixedly connected to the material-pulling block mounting seat or the material-pulling block fixing seat. The top of the base has a groove, and the elastic reset member is provided in the groove. The straight end of the material-pulling block is hinged to the groove, and the protruding end of the material-pulling block is connected to the elastic reset member.

[0017] As a further improvement of the present invention, the wire loading fixture includes a sliding plate, a wire harness loading cavity, and a loading fixture. The bottom of the sliding plate is slidably connected to the fixture slide rail, and the top of the sliding plate is connected to the wire harness loading cavity and the loading fixture respectively. The bottom of the wire harness loading cavity is slidably connected to a pulley. The wire to be transported is loaded in the wire harness loading cavity and the loading fixture.

[0018] As a general technical concept, the present invention also provides a material distribution method based on the above-mentioned unequal-distance synchronous material feeding device, comprising the following steps:

[0019] S1. The material-pushing block on the material-pushing block mounting base abuts against the wire loading fixture on the feeding station b, and the drive unit drives the guide rail to move towards the unloading station e.

[0020] S2. The pusher block mounting seat drives the pusher block to slide from the second limit seat to the first limit seat, and the wire loading fixture on the loading station b remains fixed; the pusher block on the pusher block fixing seat pushes the wire loading fixture on the positioning station c and the process station d to move towards the unloading station e.

[0021] S3. When the push block mounting seat abuts against the first limit seat, the push block on the push block mounting seat pushes the wire loading fixture on the loading station b and moves the wire loading fixture from the loading station b to the positioning station c; at this point, the push block on the push block fixing seat moves the positioning station c and the wire loading fixture on the process station d one station toward the unloading station e.

[0022] S4. The material-pushing block on the material-pushing block mounting base abuts against the wire loading fixture on the positioning station c, and the drive unit drives the guide rail to move towards the material-loading station b.

[0023] S5. The wire loading fixture on the positioning station c remains fixed, and the guide rail moves towards the loading station b until the material-picking block on the material-picking block mounting seat abuts against the second limit seat. The wire loading fixture presses down the material-picking block and moves from the positioning station c to the process station d, where it is intercepted by the material-picking block on the material-picking block fixing seat, thus completing one material-picking cycle.

[0024] S6. Repeat steps S1 to S5 to achieve cyclic material feeding.

[0025] Compared with the prior art, the advantages of the present invention are as follows:

[0026] 1. The non-uniformly spaced synchronous material feeding device of the present invention, by sequentially connecting and arranging a belt conveyor assembly, a roller assembly, and a frame, and by setting a jig slide and multiple pulleys on the frame for assisting in the conveying of the wire loading jig, and setting a non-uniformly spaced material feeding mechanism below the jig slide, realizes synchronous feeding of the wire loading jig on the frame, simplifies the structural setting of the material feeding equipment, reduces the material feeding operation time, and improves production capacity. Furthermore, the non-uniformly spaced synchronous material feeding device of the present invention has high compatibility; when applied to other similar product jigs, only the corresponding track parts need to be replaced.

[0027] 2. The non-equidistant synchronous feeding device of the present invention, by setting the distance between the first and second limiting seats in the sliding feeding block unit to X1, corresponding to the distance between the feeding station b and the positioning station c, and setting the distance between the second limiting seat and the adjacent feeding block fixing seat to X2, compensates for the distance difference between the feeding station and the positioning station and the first process station on the frame. The distance between adjacent feeding blocks on the feeding block fixing seat is X3, corresponding to the distance between adjacent process stations d, and the sum of X1 and X2 equals X3. During the process of the drive unit driving the guide rail to move back and forth for one cycle, synchronous feeding of wire loading fixtures on the feeding station b and the positioning station c or process station d is realized, which reduces the feeding operation time and improves production capacity.

[0028] 3. The material distribution method of the present invention realizes the synchronization of material distribution action and process station material distribution action through the material distribution mechanism with unequal distance. The material distribution operation between the loading and process station is completed by using a set of material distribution components, which reduces the material distribution operation time and improves production capacity.

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and specific preferred embodiments, but this does not limit the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1 to 6As shown, the non-equidistant synchronous feeding device of the present invention includes a belt conveyor assembly 100, a roller transition assembly 200, and a frame 500 arranged sequentially. A fixture slide 300, a pulley 501, and a non-equidistant feeding mechanism 400 are mounted on the frame 500, with the feeding mechanism 400 located below the fixture slide 300. Along the wire conveying direction, the fixture slide 300 and the pulley 501 are respectively arranged on opposite sides of the frame 500. The wire loading fixture 600, loaded with wire, is conveyed sequentially by the belt conveyor assembly 100 and the roller transition assembly 200 before entering the frame 500. One end of the wire loading fixture 600 is slidably connected to the fixture slide 300, and the other end is slidably connected to the pulley 501. Under the actuation of the feeding mechanism 400, the wire loading fixture 600 moves and is conveyed on the frame 500.

[0040] In this embodiment, the belt conveyor assembly 100, roller transition assembly 200, and frame 500 are sequentially connected. A fixture slide 300 and multiple pulleys 501 for assisting the conveying of the wire loading fixture 600 are provided on the frame 500. An unequal-distance material-shifting mechanism 400 is arranged below the fixture slide 300, enabling synchronous shifting of the wire loading fixture 600 on the frame 500. This simplifies the structural setup of the material-shifting equipment and reduces the material-shifting operation time. Furthermore, the unequal-distance synchronous material-shifting device in this embodiment has high compatibility; when applied to other similar product fixtures, only the corresponding track parts need to be replaced.

[0041] like Figure 2 As shown, in this embodiment, the roller transition assembly 200 is provided with a loading station b, and the frame 500 is provided with a positioning station c, a unloading station e, and multiple equally spaced process stations d. The distance between the loading station b and the positioning station c is less than the distance between the positioning station c and the process station d, and the distance between the positioning station c and the process station d is equal to the distance between adjacent process stations d. The wire loading fixture 600 is manually placed onto the belt conveyor assembly 100 and conveyed to the loading station b of the roller transition assembly 200. The wire loading fixture 600 is moved from the loading station b to the positioning station c by the material feeding mechanism 400, and then moved from the positioning station c to the process station d. It is then sequentially moved and transferred among the multiple process stations d, and finally moved to the unloading station e to complete the unloading.

[0042] like Figure 3As shown, in this embodiment, the feeding mechanism 400 includes: a sliding feeding block unit 410, a fixed feeding block unit 420, a drive unit 430, and a guide rail 440. The guide rail 440 is mounted on the frame 500 along the setting direction of the fixture slide 300, and the frame 500 is equipped with a groove 450 that cooperates with the guide rail 440. The groove 450 assists in positioning to improve the reliability of the reciprocating movement of the guide rail 440. The drive unit 430 is fixedly mounted on the side of the frame 500 through a connector, and the output end of the drive unit 430 is connected to the guide rail 440.

[0043] A sliding toggle unit 410 is slidably mounted on a guide rail 440 and reciprocates along the guide rail 440. The sliding toggle unit 410 is used to move the wire loading fixture 600 from the loading station b to the positioning station c. Multiple fixed toggle units 420 are equally spaced on the guide rail 440 and reciprocate with the guide rail 440. The fixed toggle units 420 are used to move the wire loading fixture 600 from the positioning station c to the process station d, and sequentially move it between multiple process stations d, finally moving it to the unloading station e to complete the unloading. Driven by the drive unit 430, the guide rail 440 reciprocates, thereby driving the sliding toggle unit 410 and the fixed toggle unit 420 to reciprocate, realizing the toggle and conveying of the wire loading fixture 600 on the frame 500.

[0044] like Figure 3 As shown, in this embodiment, the sliding block unit 410 includes: a first limiting seat 411, a block mounting seat 412, a second limiting seat 413, and a material-pushing block 460. The first limiting seat 411 and the second limiting seat 413 are both fixedly mounted on the guide rail 440, and the distance between the first limiting seat 411 and the second limiting seat 413 is equal to the distance between the loading station b and the positioning station c. The block mounting seat 412 is slidably mounted on the guide rail 440 and reciprocates between the first limiting seat 411 and the second limiting seat 413; the material-pushing block 460 is mounted on the block mounting seat 412 and is used to move the wire loading fixture 600.

[0045] like Figure 3 As shown, in this embodiment, the fixed lever unit 420 includes lever fixing seats 421 and lever blocks 460. Multiple lever fixing seats 421 are equally spaced on the guide rail 440, and the lever blocks 460 are mounted on the lever fixing seats 421 for levering the wire loading fixture 600. The distance between adjacent lever blocks 460 on the lever fixing seats 421 is equal to the distance between adjacent process stations d. The number of lever blocks 460 in the fixed lever unit 420 corresponds to the number of process stations on the frame 500.

[0046] like Figure 3As shown, in this embodiment, the distance between the first limiting seat 411 and the second limiting seat 413 is X1, the distance between the second limiting seat 413 and the adjacent push block fixing seat 421 is X2, and the distance between the adjacent push blocks 460 on the push block fixing seat 421 is X3. The sum of X1 and X2 is equal to X3, so as to realize the synchronous push of wire loading fixture 600 on the loading station b and the positioning station c or process station d.

[0047] In this embodiment, by setting the distance between the first limiting seat 411 and the second limiting seat 412 in the sliding block unit 410 to X1, corresponding to the distance between the loading station b and the positioning station c, and setting the distance between the second limiting seat 412 and the adjacent block fixing seat 421 to X2, the distance difference between the loading station and the positioning station and the first process station on the frame is compensated. The distance between the adjacent material feeding blocks 460 on the block fixing seat 421 is set to X3, corresponding to the distance between the adjacent process stations d, and the sum of X1 and X2 equals X3. During the process of the drive unit 430 driving the guide rail to move back and forth for one cycle, the wire loading fixtures on the loading station b and the positioning station c or process station d are synchronously fed, reducing the feeding operation time and improving production capacity.

[0048] like Figure 3 As shown, in this embodiment, the drive unit 430 includes a drive component 431, a lead screw 432, a coupling 433, and a connecting plate 435. The output end of the drive component 431 is connected to the fixed end of the lead screw 432 via the coupling 433, and the movable end of the lead screw 432 is connected to the guide rail 440 via the connecting plate 435. Driven by the drive component 431, the lead screw 432 drives the guide rail 440 to reciprocate along the frame 500, thereby driving the sliding block unit 410 and the fixed block unit 420 to move and move the wire loading fixture 600. Furthermore, to improve the movement stability of the guide rail 440, an auxiliary sliding component 434 in the form of a slide rail groove is also provided at the bottom of the movable end of the lead screw 432. The drive component 431 can specifically be in the form of a servo motor, a cylinder, or a hydraulic cylinder, as long as it can drive the guide rail 440 to move smoothly.

[0049] like Figure 4As shown, in this embodiment, the feeding block 460 includes a base 461, a feeding block 462, and an elastic reset member 463. The bottom of the base 461 is fixedly connected to the feeding block mounting base 412 or the feeding block fixing base 421. A groove is provided on the top of the base 461, and the elastic reset member 463 is provided in the groove. The straight end of the feeding block 462 is hinged to the groove, and the protruding end of the feeding block 462 is connected to the elastic reset member 463. In this embodiment, the elastic reset member 463 can specifically be a spring. During the feeding process, the protruding end of the feeding block 462 is mainly used to assist the movement of the wire loading fixture 600. When the protruding end of the feeding block 462 is squeezed by the wire loading fixture 600, it will be pressed down into the groove, so that the wire loading fixture 600 moves in the feeding direction.

[0050] like Figure 5 As shown, in this embodiment, the wire loading fixture 600 includes a sliding plate 601, a wire harness loading cavity 602, and a loading fixture 603. The bottom of the sliding plate 601 is slidably connected to the fixture slide 300 by a slider and groove fitting. The top of the sliding plate 601 is connected to both the wire harness loading cavity 602 and the loading fixture 603. The bottom of the wire harness loading cavity 602 rolls forward on the pulley 501. The wire to be transported is loaded into the wire harness loading cavity 602 and the loading fixture 603. The wire harness loading cavity 602 is an integrally formed sheet metal part.

[0051] Example 2

[0052] like Figure 7 As shown, this embodiment provides a material distribution method based on the unequal-distance synchronous material feeding device described in Embodiment 1, including the following steps:

[0053] S1, the material-pushing block 460 on the material-pushing mounting base 412 abuts against the wire loading fixture 600 on the loading station b, and the drive unit 430 drives the guide rail 440 to move towards the unloading station e. Figure 6 As shown in (A).

[0054] S2. The pusher block mounting base 412 drives the pusher block 460 to slide from the second limit seat 413 to the first limit seat 411, keeping the wire loading fixture 600 on the loading station b fixed. The pusher block 460 on the pusher block fixing base 421 pushes the wire loading fixture 600 on the positioning station c and the process station d to move towards the unloading station e. Figure 6 As shown in (B).

[0055] S3. When the pusher block mounting base 412 abuts against the first limit seat 411, the pusher block 460 on the pusher block mounting base 412 pushes the wire loading fixture 600 on the loading station b, and moves the wire loading fixture 600 from the loading station b to the positioning station c. At this point, the pusher block 460 on the pusher block fixing base 421 has moved the wire loading fixture 600 on the positioning station c and the process station d one station towards the unloading station e. Figure 6 (C) and Figure 6 As shown in (D).

[0056] S4. The material feeding block 460 on the feeding block mounting base 412 abuts against the wire loading fixture 600 on the positioning station c, and the drive unit 430 drives the guide rail 440 to move towards the loading station b. Figure 6 As shown in (E).

[0057] S5. The wire loading fixture 600 at positioning station c remains fixed, and the guide rail 440 moves towards the loading station b until the material-pushing block 460 on the material-pushing block mounting base 412 abuts against the second limit seat 413. The wire loading fixture 600 presses down the material-pushing block 460 and moves it from positioning station c to process station d, where it is intercepted by the material-pushing block 460 on the material-pushing block fixing base 421, thus completing one material-pushing cycle. Figure 6 (F) and Figure 6 As shown in (G).

[0058] S6. Repeat steps S1 to S5 to achieve cyclic material feeding.

[0059] In this embodiment, the material distribution action and the material feeding action of the process station are synchronized by the material feeding mechanism with unequal distance. The material feeding and material feeding operations between process stations are completed by using a set of material feeding components, which reduces the material feeding operation time and improves production capacity.
