Description

[0002] In the existing technology, glass tempering furnaces are equipped with multiple air supply devices, multiple heating devices, and multiple detection devices. These devices all need to be connected to external power sources, control systems, or detection systems via cables. Therefore, before assembling and producing equipment such as glass tempering furnaces, it is necessary to prepare cables of various diameters or lengths in advance according to configuration requirements.

[0003] When cables are purchased from the market, each roll of cable has a fixed length and diameter. The installer finds the corresponding roll to match the required diameter and pulls out the required length, then cuts it and sets it aside for later use. Due to the installer's physical limitations, only one cable can be pulled at a time. After pulling one cable, it is cut off before pulling the next one. The installer has to pull multiple cables to assemble the multiple cables needed for one piece of equipment, which reduces the efficiency of cable pulling and splitting and seriously affects the subsequent assembly and production progress of the glass tempering furnace equipment.

[0046] A wire pulling production line for cable harnesses includes a wire feeding device 1, a wire separating device 2, and a wire winding device 3;

[0047] The wire feeding device 1 includes a mounting frame 11, multiple trays 12 and multiple rotating shafts 14; the wire separating device 2 includes a wire separating plate 21; the wire winding device 3 includes a wire collecting plate 31 and a winding turntable 32.

[0048] Multiple rotating shafts 14 are respectively erected on the top surface of the mounting frame 11, and the tray 12 is fitted onto the outer circumferential surface of the rotating shaft 14. The tray 12 is used to support the cable reel 10.

[0049] The wire splitter 21 is mounted in front of the wire feeding device 1. The wire splitter 21 has multiple wire holes 210 staggered in the left-right direction. The wire holes 210 pass through the wire splitter 21 in the front-back direction.

[0050] The take-up turntable 32 is mounted in front of the cable splitting device 2, and the cable gathering plate 31 is installed between the take-up turntable 32 and the cable splitting plate 21. A cable gathering hole 310 is provided in the middle of the cable gathering plate 31. The cable gathering hole 310 passes through the cable gathering plate 31 in the forward direction. Each cable threading hole 210 is used to pass through one cable unwound from the cable reel 10. The cable gathering hole 310 is used to pass through multiple cables passing through all the cable threading holes 210. The take-up turntable 32 is used to take up the cable bundle composed of multiple cables passing through the cable gathering hole 310.

[0051] Figure 1 The diagram shown is a structural schematic of an embodiment of a cable harness pulling production line according to the present invention. The cable reel 10 in the diagram contains the cable to be used in the cable harness. Figure 2 This is a schematic diagram of the installation structure of one embodiment of the wire splitting device 2 and the winding device 3 of this utility model; Figure 3 This is a schematic diagram of the installation structure of one embodiment of the branching device 2 of this utility model; Figure 4 This is a schematic diagram of the installation structure of one embodiment of the winding device 3 of this utility model.

[0052] like Figure 1-4 As shown, select multiple cable reels 10 according to the cable configuration requirements of the wire harness, place the multiple cable reels 10 on multiple trays 12 respectively, then pull out one end of the cable from each cable reel 10, pass one end of each cable through the corresponding wire hole 210, and then through the cable collection hole 310. Then fix one end of the multiple cables to the winding post 321 of the take-up turntable 32 and bundle them together. Then rotate the take-up turntable 32 to wind up the cable harness composed of multiple cables. When the length of the cable harness reaches the required length, bundle the multiple cables together behind the cable collection hole 310, and cut each cable after tightening to obtain the required cable harness.

[0053] Furthermore, the branching device 2 also includes a length measuring device 22;

[0054] The wire splitting device 2 is equipped with two wire splitting plates 21, which are mounted in front of the wire feeding device 1 with a gap between them; the length measuring device 22 is installed between the two wire splitting plates 21.

[0055] like Figure 1-3 and Figure 6 As shown, the length of any cable passing between the two branch plates 21 can be measured by a length measuring device 22 installed between the two branch plates 21; preferably, the longest cable in the cable bundle that needs to be pulled is measured.

[0056] like Figure 6 The length measuring device 22 shown is equipped with an encoder pulley 222 and multiple wire pulleys 221. The multiple wire pulleys 221 are divided into two groups, with multiple wire pulleys 221 in the same group arranged at intervals. The two groups of wire pulleys 221 are located in front of and behind the encoder pulley 222, respectively. In use, the cable whose length needs to be measured is passed through the wire hole 210 of the rear distribution plate 21, then around the rear group of wire pulleys 221, then around the wheel surface of the encoder pulley 222, then around the front group of wire pulleys 221, and finally through the wire hole 210 of the front distribution plate 21. When the cable is wound up by the winding turntable 32, it will drive the encoder pulley 222 to rotate, and the length of the cable passing through the wheel surface of the encoder pulley 222 can be detected and obtained.

[0057] Based on the cable lengths tested above and the wiring paths of other cables, the corresponding lengths of other cables can also be calculated.

[0058] Furthermore, it also includes a movable frame 4, a movable motor 7, a rack 8, a control device 9, and two guide rails 5;

[0059] The multiple trays 12 are divided into multiple groups. Each group of trays 12 includes multiple trays 12 arranged sequentially in the front-back direction. Two adjacent groups of trays 12 form a wire feeding unit 120. Multiple guide frames 13 in the same wire feeding unit 120 are arranged in a row in the front-back direction.

[0060] The guide rail 5 extends in the left and right direction, and two guide rails 5 are installed in front of the mounting frame 11 with a back-to-back interval; the rack 8 is installed between the two guide rails 5; the movable frame 4 is installed on the two guide rails 5; the movable motor 7 is mounted on the bottom of the movable frame 4; and the control device 9 is mounted on the movable frame 44.

[0061] The output end of the mobile motor 7 is fitted with a gear 71; the gear 71 meshes with the rack 8; the wire splitting device 2 and the wire winding device 3 are respectively installed on the top surface of the mobile frame 4;

[0062] The mobile motor 7 is signal-connected to the control device 9; the mobile motor 7 can drive the mobile frame 4 to move along the guide rail 5 to the front of any of the wire feeding units 120.

[0063] like Figure 1 and Figure 5 As shown, the wire feeding device 1 in the figure is equipped with three wire feeding units 120. The start and stop of the moving motor 7 can be controlled by the control device 9, so that the moving motor 7 drives the moving frame 4 to move in front of any wire feeding unit 120. Then, the cable bundle is produced using the cable reel 10 placed in the wire feeding unit 120. At the same time, the cable reel 10 corresponding to the multiple cables required to produce the next wire bundle can be arranged in another wire feeding unit 120. This can reduce the downtime waiting time and thus improve the production efficiency of the production line.

[0064] Furthermore, the winding device 3 also includes a drive motor 33;

[0065] The drive motors 33 are respectively mounted on the movable frame 44; the output ends of the drive motors 33 are arranged facing upwards, the middle part of the winding turntable 32 is connected to the output end of the drive motors 33, and the control device 9 is connected to the drive motors 33 by signal.

[0066] like Figure 2 and Figure 5As shown, the start and stop of the drive motor 33 can be controlled by the control device 9, which in turn controls the rotation of the winding turntable 32, thereby controlling the length of the wound wire harness.

[0067] Furthermore, a foot pedal 24 and a proximity switch 25 are also installed at the bottom of the movable frame 4;

[0068] The front and rear ends of the foot pedal 24 are rotatably mounted on the bottom of the movable frame 4, and the left side of the foot pedal 24 is used for stepping.

[0069] The proximity switch 25 is located near the right corner of the foot pedal 24, and the proximity switch 25 is connected to the control device 9 and the drive motor 33 respectively.

[0070] Figure 3 In the embodiment shown, when the left side of the foot pedal 24 is stepped down, the right side of the foot pedal 24 tilts up and triggers the proximity switch 25. The proximity switch 25 sends a feedback signal to the control device 9. After receiving the feedback signal, the control device 9 starts or stops the drive motor 33.

[0071] In practical applications, operators can control the start and stop of the drive motor 33 by stepping on the foot pedal 24 according to the actual situation, which provides more flexible operation convenience.

[0072] Furthermore, a pull buckle 26 is also installed at the bottom of the movable frame 4;

[0073] The bottom of the mounting bracket 11 is fitted with a buckle seat 15 that matches the buckle 26.

[0074] Figure 1 and Figure 3 As shown, when the moving motor 7 drives the moving frame 4 to move in front of any wire feeding unit 120, the pull buckle 26 can be fastened in the corresponding buckle seat 15, so that the moving frame 4 is fixed on the top surface of the guide rail 5, thus preventing the moving frame 4 from moving during the production process.

[0075] Furthermore, the dividing plate 21 is equipped with a plurality of rotatable first dividing posts 211;

[0076] The gap between two adjacent first branch posts 211 forms the threading hole 210;

[0077] The wire feeding device 1 also includes multiple guide frames 13;

[0078] The guide frame 13 includes a frame 130, two second branch posts 131 and two guide rollers 132;

[0079] The frame 130 is installed on the top surface of the mounting frame 11, and the frame 130 is located between two adjacent trays 12 on the left and right; two second branching posts 131 are erected and arranged at intervals on the left and right; two guide rollers 132 are horizontally arranged and installed on the frame 130 at intervals on the top and bottom, and the two second branching posts 131 are respectively close to the rear peripheral surface of the guide rollers 132;

[0080] The second dividing post 131 and the guide roller 132 can rotate respectively.

[0081] like Figure 3 and Figure 6 The cable threading hole 210, formed by the gap between two adjacent first branch posts 211, can prevent the cable from being scratched and damaged on the branch plate during the pulling process.

[0082] like Figure 1 and Figure 6 As shown, a guide frame 13 is installed between two adjacent trays 12. In use, one end of the cable is first passed through the gap between the two second branch posts 131 and the gap between the two guide rollers 132 of the guide frame 13. Then, one end of the cable is passed through the cable hole 210 located at the rear. Then, one end of the cable is passed through the cable hole 210 located at the front. During the winding process of the winding turntable 32, the cable will drive the second branch posts 131 and the guide rollers 132 to rotate synchronously. This can prevent the cable from being scratched and damaged by the edge of the tray 12 or cable reel 10 during the pulling process.

[0083] Furthermore, the wire feeding device 1 also includes a plurality of friction rods 16;

[0084] The friction rod 16 includes a cylinder 161, a spring element, and a friction cap 162;

[0085] The cylinder 161 is positioned close to the rotating shaft 14. The lower end of the cylinder 161 is mounted on the top of the mounting bracket 11, and the upper end of the cylinder 161 faces upward toward the bottom surface of the tray 12. The spring is installed inside the cylinder 161. The friction cap 162 is fitted onto the upper end of the cylinder 161, and the upper end of the spring abuts against the friction cap 162. The top surface of the friction cap 162 abuts against the bottom surface of the tray 12.

[0086] like Figure 4 and Figure 7 As shown, by pressing the friction cap 162 upward by the spring member and making the friction cap 162 abut against the bottom surface of the tray 12, the winding turntable 32 can be rapidly decelerated after the drive motor 33 stops, so as to reduce the inertial rotation of the winding turntable 32, thereby reducing the length of loose cable exposed on the cable reel 10, and thus improving the accuracy of the cable length wound by the winding turntable 32.

[0087] In practical applications, the length measuring device 22 and the control device 9 can be set to be connected by a signal, and the display screen of the control device 9 can display the cable length measured by the length measuring device 22. When the displayed cable length reaches the value required by the process, the control device 9 will issue an alarm signal, and then each cable can be cut manually or by a cutting device.

[0088] Figure 6 The illustration shows an embodiment where each cable is cut using a cutting device. Multiple cable cutters 23 are also installed between the two branch plates 21. The cable cutters 23 are positioned near the front or rear cable insertion holes 210. Each cable cutter 23 is a pneumatic guillotine, comprising a cylinder 231, a blade 232, and a blade holder 233. The cylinder 231 is mounted above the blade holder 233, with its output end facing downwards. The blade 232 is mounted on the output end of the cylinder 231, with its cutting edge facing downwards and towards the blade holder 233. When the cable cutter 23 is not activated, the cutting edge of the blade 232 and the blade holder 233 are not closed, and the cutting hole 230 between the cutting edge and the blade holder 233 is open. Multiple cutting holes 230 correspond one-to-one with multiple cable insertion holes 210, and the cable cutter 23 is connected to the control device 9 via a signal connection.

[0089] In use, before each cable passes through the wire hole 210 in front, the cable is first passed through the cutting hole 230 of the corresponding cable cutter 23; when the display screen of the control device 9 shows that the cable length measured by the length measuring device 22 has reached the set process value, the control device 9 alarms and starts all the cable cutters 23 to cut multiple cables at the same time.

[0090] In summary, such as Figure 1-7 The embodiment of this utility model shown describes a cable harness pulling production line that guides cables from multiple cable reels 10 via a splitter plate 21, and bundles multiple cables into a single bundle via a cable collection hole 310. The bundle is then wound up by a winding turntable 32 to obtain a cable harness composed of multiple cables. This allows for the simultaneous pulling and splitting of multiple cables, resulting in high work efficiency. The cable harness, composed of multiple cables, is provided to installation personnel in the subsequent glass tempering furnace assembly production and used for electrical connections between various electrical equipment. Furthermore, it effectively improves the work efficiency of the subsequent glass tempering furnace assembly production.

[0091] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
