Description

Technical Field

[0001] The invention relates to the field of electric wire production, and in particular to an automatic production line for paralleling multiple wire harnesses of lighting fixtures. Background Art

[0002] When producing lighting wiring harnesses, multiple strands of wiring harnesses must first be wound together, and then passed through a powdering machine so that the talcum powder in the powdering machine adheres to the surface of the wiring harness to form a talcum layer. The wiring harness then passes through the covering head of a coating machine to allow hot-melt rubber to wrap the wiring harness, forming a rubber layer on the surface of the talcum layer to complete the wiring harness wrapping production.

[0003] When the wire harness is transported out of the powder coating machine and then enters the sheathing head, the talcum powder adhering to the surface of the wire harness is easily shaken off due to the shaking of the wire harness, resulting in uneven thickness of the talc layer after the wire harness is produced, making it easy for hot spots and resistance to appear in places where the talc layer is thinner. Summary of the invention

[0004] The present application provides an automated production line for paralleling multiple wiring harnesses of lighting fixtures, which can improve the adhesion between talcum powder and the wiring harnesses, reduce the falling of talcum powder during wiring harness transmission, and ensure the uniformity of the thickness of the talcum layer after cable production.

[0005] The present application provides a lighting multi-wiring harness paralleling automatic production line adopts the following technical solution:

[0006] The cam is an axially-coupled device which is adapted to move the two members of the control wheel to abut against each other against the movement of the control wheel, and a plurality of cams are provided on the cam to couple the two members of the control wheel to the control wheel.

[0007] By adopting the above technical scheme, a plurality of wire harnesses as raw materials will form a wire harness with a larger diameter after being wound by the winding device, and then this wire harness will enter the first storage compartment through the wire inlet and pass through the talcum powder in the storage compartment, so that the talcum powder adheres to the surface of the wire harness, and then the wire harness adhered with talcum powder enters the connecting channel and passes through the extrusion channel. When the wire harness passes through the extrusion channel, under the action of multiple driving parts 2, multiple sliders move toward the wire harness, so that multiple pressure rollers are squeezed on the surface of the wire harness, and at the same time, the driving part drives the annular member to rotate, and the rotation of the annular member will drive the rotation of multiple pressure rollers, so that multiple pressure rollers spirally squeeze the talcum powder on the surface of the wire harness, and squeeze the talcum powder attached to the surface of the wire harness into the gap between the wire harnesses, so as to improve the connection firmness between the talcum powder and the wire harness, so that a layer of firm talcum powder layer is formed on the surface of the wire harness. When multiple pressure rollers rotate to extrude talcum powder, the friction between the talcum powder and the pressure rollers will cause the talcum powder layer after forming to carry static electricity. Then the extruded wire harness will enter the second storage compartment. Under the effect of electrostatic adsorption, the surface of the extruded talcum powder layer will firmly adsorb another layer of talcum powder to supplement the talcum powder squeezed off by multiple tablets on the wire harness, so that there is enough talcum powder adhering to the surface of the wire harness. The adhesion between talcum powder and the wire harness can be improved by extrusion and electrostatic adsorption, and the talcum powder falling during the transmission of the wire harness between the powder passing mechanism and the coating mechanism can be reduced. At the same time, the spiral extrusion method will make the extruded wire harness and the talcum powder layer attached to its surface tend to be cylindrical, so that the thickness of the second layer of talcum powder adsorbed by electrostatic adsorption is also more uniform, ensuring the uniform thickness of the wire harness wrapped with talcum powder. This will also make the thickness of the rubber wrapped on the surface of the talcum powder layer after the wire harness enters the coating device more uniform, ensuring the overall performance of the produced wire harness.

[0008] Preferably, the diameter of the pressing roller gradually decreases from an end close to the wire inlet to an end far from the wire inlet.

[0009] By adopting the above technical solution, the size of the extrusion space is gradually reduced from the side close to the wire inlet to the side far from the wire inlet, thereby improving the smoothness of talcum powder on the surface of the wire harness when multiple rollers are spirally extruded, reducing the falling of talcum powder when multiple rollers are spirally extruded, and ensuring that there is enough talcum powder to fill the gaps between the wire harnesses, so that the first layer of talcum powder can be firmly attached to the surface of the wire harness.

[0010] Preferably, the driving part 1 includes a gear 1 sleeved on the outer wall of the ring member and a gear 2 sleeved on the rotating rod, the rotating rod is located below the ring member, and the gear 1 is meshed with the gear 2.

[0011] By adopting the above technical solution, when the rotating rod is started, the ring member will be driven to rotate through the cooperation of gear 2 and gear 1, so that the multiple pressure rollers can spirally squeeze the talcum powder on the surface of the wire harness.

[0012] Preferably, a plurality of shovel blades are provided on a surface of the annular member close to the line inlet, the plurality of shovel blades are arranged obliquely, and the plurality of shovel blades all contact with the channel wall of the connecting channel.

[0013] By adopting the above technical solution, during the rotation of the annular member, the multiple shovel blades will scoop up and lift the talcum powder that falls into the connecting channel. The talcum powder that falls into the connecting channel includes the talcum powder scraped off by the multiple scrapers and the talcum powder shaken off during the bundle transmission process. When the talcum powder is scooped up and lifted, when the shovel blade is about to rise to the highest point, the talcum powder will fall onto the wire harness again to supplement the talcum powder shaken off during the wire harness transmission process, so that there is enough talcum powder on the surface of the wire harness when the wire harness passes through the extrusion channel.

[0014] Preferably, a receiving bucket is provided in the connecting channel, the receiving bucket extends between the multiple shovel blades, a material leakage groove is provided at the bottom of the receiving bucket, and the material leakage groove is located above the wire harness transmission path.

[0015] By adopting the above technical solution, a receiving bucket is provided to receive the talcum powder scooped up by the shovel blade, and the talcum powder entering the receiving bucket will fall onto the wire harness more accurately through the leakage chute.

[0016] Preferably, a plurality of mounting columns are provided on the inner wall of the annular member, a plurality of the slide grooves are respectively opened on the plurality of mounting columns, a threaded column is provided on the mounting column, a plurality of threaded holes matching with the threaded column are opened on the inner wall of the annular member, and a plurality of the driving parts are respectively arranged on the plurality of mounting columns.

[0017] By adopting the above technical solution, the number of mounting posts can be adjusted according to the size of the wiring harness, thereby adjusting the number of pressure rollers, so that the pressure rollers can better extrude and wrap the talcum powder when rotating and extruding, thereby ensuring the spiral extrusion effect of the pressure rollers on the talcum powder on the surface of the wiring harness.

[0018] Preferably, the second driving part comprises a spring arranged in the slide groove, and the elastic force of the spring acts on the slider to drive the slider to move toward the axis of the annular member.

[0019] By adopting the above technical solution, the spring drives the slider to move toward the wire harness, so that the pressure roller presses against the wire harness.

[0020] Preferably, the driving part 2 includes a gear 3 rotatably connected in the slide groove, a plurality of tooth grooves opened on the slide groove and meshing with the gear 3, and a rack slidably connected in the slide groove, the weight of the rack is greater than the weight of the slider, and the distance from the rack to the inner wall of the ring member is always smaller than the distance from the slider to the inner wall of the ring member.

[0021] By adopting the above technical solution, when the annular member rotates, the slider and the rack will generate centrifugal force. Because the centrifugal force of the rack will be greater than the centrifugal force of the slider, the rack will move toward the inner wall of the annular member, and drive the slider to move toward the wire harness through gear three, so that the pressure roller squeezes the wire harness. The faster the rotation speed of the annular member, the greater the squeezing force of the pressure roller on the wire harness and talcum powder. Therefore, the rotation speed of the annular member can be adjusted according to actual needs, thereby adjusting the squeezing force of the pressure roller on the wire harness and talcum powder, so that the squeezing force of the pressure roller is maintained in a reasonable range, preventing the phenomenon of deformation of the wire harness caused by excessive squeezing force and the phenomenon of poor adhesion of talcum powder caused by insufficient squeezing force.

[0022] The technical effects of the present invention are mainly reflected in the following aspects:

[0023] 1. The present invention can improve the adhesion between talcum powder and the wiring harness by extrusion and electrostatic adsorption;

[0024] 2. The present invention uses spiral extrusion to make the thickness of the talcum powder layer adhered to the surface of the wiring harness more uniform;

[0025] 3. The present invention adds talcum powder to the wire harness before it is extruded to replenish the talcum powder shaken off during the transmission of the wire harness, so that there is enough talcum powder on the surface of the wire harness when the wire harness passes through the extrusion channel.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings to make the technical solution of the present application easier to understand and grasp. Embodiment 1:

[0035] Reference Figure 1 In this embodiment, a lighting multi-wire harness paralleling automatic production line includes a winding device 11, a powdering device 12, and a coating device 13. The winding device 11 and the coating device 13 are both traditional cable production equipment, which are common knowledge and will not be described in detail in this application.

[0036] Reference Figure 2-Figure 4 The powder passing device 12 includes a body 2, on which two storage compartments 21 and a connecting passage 22 for connecting the two storage compartments 21 are provided, and the connecting passage 22 is located between the two storage compartments 21. A line inlet 23 and a line outlet 24 are respectively provided on the side walls of the two storage compartments 21 away from each other.

[0037] Reference Figure 2-Figure 4 The machine body 2 is rotatably connected with a rotating rod 25, and the two ends of the rotating rod 25 extend into the two storage compartments 21 respectively. The two ends of the rotating rod 25 are fixed with spiral propeller blades 26. The machine body 2 is provided with a motor 27 connected with the rotating rod 25. The rotating rod 25 is located below the connecting passage 22. When the motor 27 drives the rotating rod 25 to rotate, the rotating rod 25 drives the two propeller blades 26 to rotate, so that the talcum powder in the two storage compartments 21 is continuously stirred to prevent the talcum powder from sticking.

[0038] Reference Figure 3-Figure 5 The connecting passage 22 is rotatably connected with a ring member 3, a part of the ring member 3 is located in the connecting passage 22, and another part of the ring member 3 extends into the cavity inside the body 2. The body 2 is provided with a driving part 14 for driving the ring member 3 to rotate, and the driving part 14 includes a gear 141 sleeved on the outer wall of the ring member 3 and a gear 242 sleeved on the rotating rod 25, and the gear 141 is meshed with the gear 242, wherein the gear 141 and the gear 242 are both located in the cavity inside the body 2.

[0039] Reference Figure 3-Figure 5 The inner wall of the ring member 3 is provided with a plurality of threaded holes 31, and the plurality of threaded holes 31 are arranged circumferentially. The inner wall of the ring member 3 is also provided with a plurality of mounting posts 81, and the mounting posts 81 are provided with threaded posts 82, and the threaded posts 82 are connected to the threaded holes 31. The axes of the plurality of mounting posts 81 are perpendicular to and intersect with the axis of the ring member 3.

[0040] Reference Figure 3-Figure 5 , a plurality of mounting posts 81 are provided with a slide groove 51 along their respective length directions, a guide rod is fixedly connected in the slide groove 51, and a slider 52 is slidably connected to the guide rod along the length direction of the slide groove 51. A pressing roller 53 is rotatably connected to the ends of the plurality of sliders 52 that are close to each other, and an extrusion channel 54 is formed between the plurality of pressing rollers 53 for the wire harness 9 to pass through. The diameter of the pressing roller 53 gradually decreases from the end close to the wire inlet 23 to the end far from the wire inlet 23.

[0041] Reference Figure 3-Figure 5 , a driving part 2 6 for driving the slider 52 to slide toward the axis of the ring member 3 is provided in each of the plurality of slide grooves 51. The driving part 2 6 includes a spring 61 provided in the slide groove 51, the spring 61 is located on the side of the slider 52 away from the pressure roller 53, and the spring 61 is sleeved on the guide rod. One end of the spring 61 is in conflict with the side wall of the slide groove 51 close to the ring member 3, and the other end of the spring 61 is in conflict with the end of the slider 52 close to the ring member 3. The spring 61 is always in a compressed state, and the elastic force of the spring 61 acts on the slider 52 to drive the slider 52 to move toward the axis of the ring member 3.

[0042] Reference Figure 3 and Figure 4 A plurality of shovel blades 55 are provided on one side of the ring member 3 near the wire inlet 23, and the plurality of shovel blades 55 are circumferentially distributed on the ring member 3. The plurality of shovel blades 55 are arranged obliquely, and the plurality of shovel blades 55 all conflict with the channel wall of the connecting channel 22. A receiving bucket 7 is fixed on the inner wall of the connecting channel 22 near the wire inlet 23, and one end of the receiving bucket 7 extends between the plurality of shovel blades 55. A material leakage groove 71 is provided at the bottom of the receiving bucket 7, and the material leakage groove 71 is located above the transmission path of the wire harness 9.

[0043] Reference Figure 1-Figure 6 The steps of producing lighting wiring harnesses on the production line of this application are as follows:

[0044] The multiple wire harnesses 9 as raw materials will form a wire harness 9 with a larger diameter after being wound by the winding device 11. Then, the wire harness 9 will enter the first storage compartment 21 through the wire inlet 23 and pass through the talcum powder in the storage compartment 21, so that the talcum powder adheres to the surface of the wire harness 9. Then, the wire harness 9 adhered with talcum powder enters the connecting channel 22 and passes through the extrusion channel 54.

[0045] After the wire harness 9 enters the extrusion channel 54, the talcum powder in the receiving bucket 7 will be guided by the leakage groove 71 and fall onto the wire harness 9 more accurately to replenish the talcum powder on the wire harness 9. Then the wire harness 9 will enter and pass through the extrusion channel 54. During this process, the multiple springs 61 will drive the slider 52 to move to squeeze the multiple pressure rollers 53 on the surface of the wire harness 9. At the same time, the rotating rod 25 will drive the ring member 3 to rotate through the gear 1 41 and the gear 2 42. The rotation of the ring member 3 will drive the multiple pressure rollers 53 to rotate, so that the multiple pressure rollers 53 spirally squeeze the talcum powder on the surface of the wire harness 9, and squeeze the talcum powder attached to the surface of the wire harness 9 into the gap between the wire harnesses 9, thereby improving the connection firmness between the talcum powder and the wire harness 9, so that a firm layer of talcum powder is formed on the surface of the wire harness 9.

[0046] When the multiple pressing rollers 53 rotate to squeeze the talc powder, the friction between the talc powder and the pressing rollers 53 will cause the formed talc powder layer to be charged with static electricity. Then the squeezed wire harness 9 will enter the second storage compartment 21, and under the adsorption effect of static electricity, the surface of the squeezed talc powder layer will firmly adsorb another layer of talc powder to supplement the talc powder squeezed off by the multiple pressing tablets on the wire harness 9.

[0047] The adhesion between talcum powder and the wire harness 9 can be improved by extrusion and electrostatic adsorption, and the talcum powder can be reduced from falling during the transmission of the wire harness 9 between the powder passing mechanism and the coating mechanism. At the same time, the spiral extrusion method will make the wire harness 9 after extrusion and the talcum powder layer attached to its surface tend to be cylindrical, so that the thickness of the second talcum powder layer adsorbed by electrostatic adsorption is also relatively uniform, ensuring the uniform thickness of the wire harness 9 wrapped with talcum powder, which will also make the thickness of the rubber wrapped on the surface of the talcum powder layer relatively uniform after the wire harness 9 enters the coating device 13, ensuring the overall performance of the produced wire harness 9.

[0048] After the wire harness 9 is wrapped with talcum powder, the wire harness 9 is transmitted from the wire outlet 24 and enters the coating device 13, which will coat a layer of rubber on the surface of the talcum powder layer to complete the production of the wire harness 9. The wire harness 9 wrapped with rubber will enter the water pool for cooling and shaping, and the wire harness 9 after cooling and shaping will be wound and collected.

[0049] Embodiment 2: The difference between Embodiment 1 and Embodiment 2 is as follows.

[0050] Reference Figure 6 and Figure 7The driving part 2 6 in the second embodiment includes a gear 3 62 rotatably connected to the slide slot 51, a plurality of tooth grooves 63 provided on the slide slot 51 and meshing with the gear 3 62, and a rack 64 slidably connected to the slide slot 51 along the length direction of the mounting column 81, wherein the rotation axis of the gear 3 62 is parallel to the axis of the ring member 3. The weight of the rack 64 is greater than the weight of the slider 52, and the distance from the rack 64 to the inner wall of the ring member 3 is always less than the distance from the slider 52 to the inner wall of the ring member 3.

[0051] Reference Figure 6 and Figure 7 When the ring 3 rotates, the slider 52 and the rack 64 will generate centrifugal force. Because the centrifugal force of the rack 64 is greater than the centrifugal force of the slider 52, the rack 64 will move toward the inner wall of the ring 3, and drive the slider 52 to move toward the wire harness 9 through the gear three 62, so that the pressure roller 53 squeezes the wire harness 9. The faster the rotation speed of the ring 3 is, the greater the squeezing force of the pressure roller 53 on the wire harness 9 and the talcum powder.

[0052] Reference Figure 6 and Figure 7 Therefore, the rotation speed of the annular member 3 can be adjusted according to actual needs, thereby adjusting the extrusion pressure of the pressing roller 53 on the wire harness 9 and the talc, so that the extrusion pressure of the pressing roller 53 is maintained in a reasonable range, preventing the deformation of the wire harness 9 caused by excessive extrusion pressure and the poor adhesion of talc caused by insufficient extrusion pressure.

[0053] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
