Description

Technical Field

[0001] The invention relates to the technical field of production and manufacturing of electronic musical instrument wiring harness accessories, and specifically proposes an electronic musical instrument wiring harness plug-in device. Background Art

[0002] An electronic musical instrument wiring harness is a collection of wires specially designed to connect electronic musical instruments and their related equipment; audio plugs are an important part of electronic musical instrument wiring harnesses, and usually audio cables with specific types of plugs are used to match corresponding sockets to correctly transmit sound signals between electronic instruments and audio equipment.

[0003] like Fig.15 The figure shows the tip of a type of audio plug. The tip is the frontmost part of the audio plug and serves as a metal conductor for transmitting audio signals. In addition, the sleeve is the outer part of the rear of the plug and serves as a metal conductor for grounding. The tip and the sleeve together constitute the tip of the audio plug. Fig.13 The insulator of this type of audio plug is shown in the figure. The tip is usually inserted into the insulator by interference fit. The insulator is used to separate the tip and the sleeve, making the tip and the sleeve two different conductive parts. The insulator is made of plastic. In actual production, it is made by injection molding. Fig.13 The continuous injection molded part shown in the figure comprises a plurality of insulators evenly distributed in a straight line, and the plurality of insulators are connected to the same injection nozzle.

[0004] In the plug-in assembly between the insulator and the tip, generally, the tips with the same number as the insulators in the continuous injection mold are manually positioned and inserted into the tip holes of the correspondingly designed positioning mold, so that the multiple tips are distributed in accordance with the distribution of the insulators in the continuous injection mold; and the continuous injection mold is positioned and placed in the corresponding down-pressing mold, so that the multiple insulators in the continuous injection mold are aligned one by one with the multiple positioned tips, and finally, the continuous injection mold is actively pressed down, so that the tips are passively inserted into the insulators at the corresponding positions, so as to achieve the tight-fitting plug-in assembly between the tips and the insulators. After the assembly is completed, the insulators can be separated from the injection nozzle. When the tips are manually plugged in between the insulators, the following problems obviously exist: 1) The tips need to be manually inserted into the tip holes one by one, and after the tips are placed, the positioning mold needs to be aligned and placed under the down-pressing mold, and after the plug-in is completed, the tips need to be ejected from the positioning mold together with the continuous injection mold. The whole process is time-consuming and labor-intensive through manual operation, and the efficiency is low. In the process of large-scale plug-in assembly, manual simple and repeated operations are required.

[0005] 2) Since the tip and the insulator are installed in a tight fit, the accuracy of placing the tip in the tip hole must also be ensured. There is generally a certain amount of resistance when the tip is inserted into the tip hole, which makes it more laborious to manually insert and remove the tip from the tip hole. Long-term operation can easily cause manual muscle strain. Summary of the invention

[0039] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] An electronic musical instrument wiring harness plugging device is used to perform a corresponding plugging operation on a tip 73 in an audio plug of an electronic musical instrument wiring harness and an insulator 72 in a continuous injection molded part 71.

In this embodiment, the electric turntable 1 rotates intermittently for one-third of a circle each time, and the three tip molds 2 are always in a Figure 3 In the position shown, a tip die 2 is located opposite to the tip conveyor 3 and the transfer insertion mechanism 4, which is a loading station, a tip die 2 is located opposite to the plug-in actuator 5, which is a plug-in station, and a tip die 2 is located opposite to the matching unloading component 6 ( Figure 3 The unloading assembly 6 is hidden under the tip die 2. Figure 2 As can be seen), it is the unloading station. Figure 3 As shown, when the electric turntable 1 rotates clockwise for one circle, for one of the tip molds 2, it passes through the loading station, the plugging station and the unloading station in sequence, thereby completing a whole process cycle operation of plugging the tip 73 relative to the insulator 72.

[0042] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Fig.16 As shown, the tip die 2 includes a positioning die 21 and a lower support plate 22 horizontally hinged on the hinge seat slide rail 12. The positioning die 21 is composed of two half-templates 211 spliced ​​in half. The two half-templates 211 are horizontally relatively set and slidably installed on the hinge seat slide rail 12 through sliding feet 2111, and the sliding direction of the half-templates 211 is vertically set relative to the rotation radial direction of the electric turntable 1; the positioning die 21 is evenly provided with a plurality of tip holes 212 on the splicing line of the two half-templates 211, and the tip holes 212 are in a vertical through structure, and the distribution spacing of the plurality of tip holes 212 is the same as that of the half-templates 211. Fig.13 The distribution spacing of the plurality of insulators 72 is equal, and the radius of the tip hole 212 corresponds to the radius size of the tip 73, such as Fig.15The tip 73 shown has a step structure. When the tip 73 is inserted into the tip hole 212, the step of the tip 73 is uniformly overlapped on the upper end surface of the positioning mold 21; a supporting linkage 23 is assembled between the lower support plate 22 and the two half molds 211; the supporting linkage 23 includes a guide rod 231 installed on the hinge seat slide rail 12 along the rotation radial direction of the electric turntable 1. The vertical cross-section of the guide rod 231 is square, and the end of the guide rod 231 away from the center of the electric turntable 1 is welded with a terminal. The guide rod 231 is provided with a return spring 233, and the two ends of the return spring 233 are respectively welded to the hinge seat slide rail 12 and the end block 232; the end block 232 is vertically hinged with two horizontally symmetrically distributed push-pull connecting rods 234, and the other ends of the two push-pull connecting rods 234 are hinged to the two half-forms 211 one by one; the end block 232 is horizontally hinged with a support connecting rod 235, and the other end of the support connecting rod 235 is hinged to the bottom end of the lower support plate 22.

Obviously, on the one hand, the end block 232 drives the two half templates 211 to slide and separate relative to each other through two push-pull connecting rods 234, and the continuous injection molded part 71 with the tip 73 plugged in can pass through the two half templates 211. On the other hand, the end block 232 drives the lower support plate 22 to tilt downward through the supporting connecting rod 235, and the lower support plate 22 in an inclined state can be used as a blanking slide plate, so that the continuous injection molded part 71 after passing through can slide down along the lower support plate 22 surface, playing the role of unloading buffer, and avoiding the tip 73 from falling vertically and colliding with the table surface.

[0043] like Figure 7 , Figure 8 , Fig. 9 and Fig.16As shown, the tip conveyor 3 includes a tip guide rail 31, and the tip guide rail 31 includes two side block guide bars 32 arranged horizontally and symmetrically, and the side block guide bars 32 are fixed on the workbench surface through a support seat; in the present embodiment, the tip guide rail 31 is at the conveying end position in the entire tip conveyor 3, and during the actual conveying process, the tip 73 moves along the gap between the two side block guide bars 32, and the step of the tip 73 overlaps the upper end surface of the two side block guide bars 32, and the tip guide rail 31 is a non-powered guiding conveying structure of the tip 73. Therefore, the tip conveyor 3 may also include a disc material sorting machine for automatically sorting and conveying the tip 73 and a transfer conveyor arranged between the disc material sorting machine and the tip guide rail 31. The disc material sorting machine is an existing material sorting and conveying equipment. The transfer conveyor is also provided with two guide frame structures that are connected to the two side block guide bars 32 one by one, and electric conveyor belts are installed on the two guide frames.

In order to form an avoidance position, the side block guide bar 32 is provided with an avoidance notch for avoiding the grab block 422, and the tips 73 located on the two side block guide bars 32 are exposed relative to the avoidance notch; the two grab blocks 422 are provided with a clamping groove 4221 for clamping the grabbing tips 73 on the opposite surfaces.

[0046] like Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.16 As shown, the stroke plate 413 is equipped with a grabbing drive assembly 43 that drives multiple grabbing assemblies 42 to grab multiple tips 73 one by one; the grabbing drive assembly 43 includes a No. 1 cylinder 431 vertically fixed to the top of the stroke plate 413 by screws, and the output end of the No. 1 cylinder 431 is hinged with two No. 1 connecting rods 432, and the other ends of the two No. 1 connecting rods 432 are correspondingly hinged with a series guide rod 433, and the two series guide rods 433 are distributed on both sides of a row of central sliders 421, and the multiple grabbing blocks 422 located on the same side of a row of central sliders 421 are horizontally slidably installed on the series guide rod 433 on the same side.

[0047] like Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.16As shown, the travel plate 413 is also equipped with a dispersed connecting rod assembly 44 that drives multiple grabbing assemblies 42 to be evenly spaced and distributed; the dispersed connecting rod assembly 44 includes a No. 2 cylinder 445 horizontally fixed on the double guide sleeve frame 4131 by screws, the output direction of the No. 2 cylinder 445 is along the sliding direction of the center slider 421, and the output end of the No. 2 cylinder 445 is fixed on the center slider 421 farthest from the baffle 4133; two groups of No. 2 guide pins 443 are horizontally symmetrically welded on the top of the travel plate 413, each group has two, and the No. 2 guide pins 443 are axially arranged parallel to the No. 1 guide pin 4211, and the travel plate 413 is provided with two groups of No. 2 guide pins 443.

Obviously, when the output rod of the No. 2 cylinder 445 is gradually extended, the center slider 421 will be pulled, so that the multiple grabbing assemblies 42 are kept in an equidistant state along the guide rail 4132 and unfolded in sequence, and the spacing gradually increases. In this embodiment, when the output rod of the No. 2 cylinder 445 is not extended, the distribution spacing of the grabbing assemblies 42 is the same as the distribution spacing of the multiple tips 73 arranged in contact with each other in sequence.

[0048] In actual operation, under the automatic material handling and conveying of the disc material handling machine and the transfer and conveying of the transfer conveyor, the tips 73 will be contacted and arranged in sequence at the tip guide rail 31 through the blocking positioning of the baffle 4133.

[0049] At the loading station, the transfer and insertion mechanism 4 will automatically complete the loading of the tip 73 of the tip mold 2 at the loading station. Specifically, after the No. 1 cylinder 431 is started, the two No. 1 connecting rods 432 drive the two serial guide rods 433 to approach each other, thereby synchronously driving the two grab blocks 422 in each grab assembly 42 to approach each other, and then clamping and grabbing the tip 73 at the corresponding position in the slot 4221 of the two grab blocks 422; then, the spacing of multiple grab assemblies 42 is driven to expand in sequence through the dispersion connecting rod assembly 44, and the spacing of multiple grabbed tips 73 is synchronously expanded, and the distribution spacing of the tips 73 after expansion is equal to the spacing of the tip holes 212, and then , the travel plate 413 moves to above the tip die 2 at the loading station, so that the multiple tips 73 are aligned one by one just above the multiple tip holes 212, and then, the grabbing drive assembly 43 releases the grabbing assembly 42, and the tip 73 is aligned and falls into the tip hole 212 below in a free fall state. It should be noted that the lower end of the tip 73 is close to the end of the tip hole 212, the end of the tip hole 212 is chamfered, and the lower end of the tip 73 is pointed, so the tip 73 can fall normally in the tip hole 212; after completing the loading of the tip 73, the transfer and insertion mechanism 4 is reset as a whole, and as the feeding continues, the tip 73 is arranged again in the tip guide rail 31.

[0050] like Figure 1 , Fig.12 , Fig.14 and Fig.16As shown, the plug-in actuator 5 includes a lifting frame 51 and an injection mold 52 for positioning and placing the continuous injection molded part 71. The lifting frame 51 includes a lifting guide rail 511 vertically fixed on the table and a lifting seat 512 vertically slidably installed on the lifting guide rail 511. The lifting seat 512 can be lifted and driven by a hydraulic cylinder; the injection mold 52 includes a cavity block 521 fixed to the lifting seat 512 by bolts. The cavity block 521 is provided with a positioning cavity 5211 for inserting and placing the continuous injection molded part 71 from the bottom to the top. The inner contour of the positioning cavity 5211 matches the outer contour of the injection nozzle of the continuous injection molded part 71. Two symmetrically arranged positioning blocks 522 are installed on the cavity block 521 so as to slide horizontally below the positioning cavity 5211; a plurality of positioning clamping grooves 5221 for clamping the insulator 72 are arranged one by one on the opposite surfaces of the two positioning blocks 522, and the number and distribution spacing of the positioning clamping grooves 5221 and the insulating parts in the continuous injection molded part 71 are the same; the two positioning blocks 522 can be connected to the output end of a cylinder, and the cylinder can be installed on the outer wall of the cavity block 521 through a fixed block, so that the positioning blocks 522 are driven to slide by the cylinder. It should be noted that the cylinder is not shown in the drawings. During operation, the continuous injection molding part 71 can be manually inserted into the positioning cavity 5211. After releasing the hand, the continuous injection molding part 71 is kept in the positioning cavity 5211 under the action of contact friction. Then, the two positioning blocks 522 slide relatively close to each other. On the one hand, the upper end faces of the two positioning blocks 522 press the continuous injection molding part 71 tightly into the positioning cavity 5211. On the other hand, each insulator 72 is clamped in the corresponding two positioning clamping grooves 5221, thereby realizing the overall locking and positioning of the continuous injection molding part 71. The clamping effect of the positioning clamping grooves 5221 on the insulator 72 improves the alignment accuracy and stability of the insulator 72 relative to the tip 73 when plugged in. The positioning and locking of the continuous injection molding part 71 can be completed during each pause interval of the electric turntable 1. In order to free up manpower and improve the overall automation level, the continuous injection molding part 71 can also be inserted and placed by installing a matching manipulator instead of manually.

[0051] Under the intermittent rotation and displacement of the electric turntable 1, the tip mold 2 that has completed loading rotates to the plug-in station. Subsequently, the lifting seat 512 drives the injection mold 52 to descend, causing the continuous injection molded part 71 to descend accordingly, and the tip 73 is passively plugged into the corresponding insulator 72 to complete a tight fit. Before the lifting seat 512 rises and resets, the positioning block 522 releases the continuous injection molded part 71. Subsequently, the injection mold 52 rises with the lifting seat 512, and the continuous injection molded part 71 is separated from the positioning cavity 5211, and the tip 73 and the continuous injection molded part 71 complete a tight fit.

[0052] The electric turntable 1 rotates intermittently again, and the tip mold 2 after the tip 73 is plugged in rotates to the unloading station. Then, the No. 3 cylinder 61 is started, and the end block 232 is pushed by the push block 62, so that the two half templates 211 are separated, and the lower support plate 22 tilts downward, and the continuous injection molded part 71 with the tip 73 plugged in slides along the lower support plate 22 to complete automatic unloading.

[0053] The present invention provides an electronic musical instrument wiring harness plug-in device, which can realize the station rotation switching of the loading station, the plug-in station and the unloading station through the electric turntable 1, and three tip molds 2 for positioning, inserting and placing the tips 73 are matched with the three stations, so that continuous position change operation can be realized; the tip conveyor 3 is set to ensure the guided transportation of the tips 73, and a transfer and insertion mechanism 4 is matched with the tip conveyor 3. The transfer and insertion mechanism 4 can complete the grabbing of a specified number of tips 73, the equidistant and dispersed arrangement of the tips 73, and the automatic placement of the tips 73 relative to the tip holes 212 in the tip mold 2 at the loading station, and the plug-in actuator 5 set at the plug-in station can be used to perform the continuous injection molding 71 before plugging. It can be positioned and locked, and can drive the continuous injection molded part 71 to complete the automatic tight fit and plugging with the tip 73. Through the structural design of the tip mold 2 and the matching unloading component 6 installed at the unloading position, the continuous injection molded part 71 with the tip 73 plugged in can be automatically buffered and unloaded at the unloading position. In summary, the device provided by the present invention can complete the continuous operations of automatic positioning and loading, automatic tight fit and plugging, and automatic buffer unloading of the tip 73 during the plug-in assembly process of the tip 73 and the insulator 72 in the audio plug of the electronic musical instrument wiring harness. There is no need for manual insertion and placement of the tip 73 and ejection of the tip 73, which avoids simple repetitive operations, saves manual physical labor, and greatly improves the production and assembly efficiency.
