Abstract
Description
Technical Field
[0001] This invention relates to the field of automated wire harness processing, and more particularly to a device for processing and assembling heat shrink tubing over a waxed tube. Background Technology
[0002] White wax tubing, also known as fiberglass tubing, is made by braiding fiberglass yarn into a sheath and then coating it with resin and treating it at high temperatures. Its main components are silicon dioxide and aluminum oxide, so it is relatively hard. Due to its good insulation, heat resistance, corrosion resistance, and mechanical strength, it is often used as an insulating protective material for wires. Moreover, white wax tubing is a braided sheath with heat dissipation gaps, so it has good heat dissipation capabilities. Heat shrink tubing is a special type of heat shrink tubing made of polyolefin material. It has the functions of high-temperature shrinkage, flexibility, flame retardancy, insulation, and corrosion resistance. It is widely used for the protection of wire harnesses and solder joints, as well as for the corrosion and rust prevention of metal rods and cables.
[0003] Because PVC tubing and heat shrink tubing offer different protective effects, when both types of tubing are needed, the heat shrink tubing is typically fitted over the PVC tubing. The fitted area is then heated to shrink the heat shrink tubing and allow it to adhere to the PVC tubing. In current production processes, this fitting and shrinking process is done manually. After manually fitting the tubing, a hot air gun is used to shrink it, resulting in low production efficiency. Therefore, it is necessary to design a highly automated machine to replace repetitive labor and reduce labor costs. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device that can automatically perform feeding, sleeve, shrinking and unloading of waxed tubing and heat shrink tubing, so as to replace manual work of inserting and shrinking waxed tubing, improve production efficiency and reduce costs.
[0005] To achieve the above objectives, the present invention provides a fully automatic heat shrink tubing threading and positioning shrinking machine, comprising a worktable, a wax tubing feeding mechanism and a heat shrink tubing feeding mechanism arranged on the rear side of the worktable, the bottom of the wax tubing feeding mechanism being relatively long and therefore located on the outer side of the rear end of the machine table, the wax tubing feeding mechanism being located on one side of the heat shrink tubing feeding mechanism, the other side of the heat shrink tubing feeding mechanism being provided with a heat shrink tubing heating mechanism and a feeding mechanism, a conveying mechanism being arranged on the front side of the worktable, a single vibrator being provided between the conveying mechanism and the wax tubing feeding mechanism, the function of the single vibrator being to vibrate the wax tubing pushed out by the wax tubing feeding mechanism sequentially to the corresponding position of the conveying mechanism, and a sleeve cutting mechanism being provided between the conveying mechanism and the heat shrink tubing feeding mechanism;
[0006] The conveying mechanism includes a first electric cylinder that spans the wax tube feeding mechanism, the heat shrink tubing feeding mechanism, and the heat shrink tubing heating mechanism. The first electric cylinder has a long lateral span, thus requiring only one sliding device to realize the conveying, tubing, and heating processes of the wax tube. A second electric cylinder, which can slide along the first electric cylinder, is placed longitudinally on the first electric cylinder. A conveying slider, which can slide along the second electric cylinder, is provided on the second electric cylinder. Multiple metal rods are fixed to one side of the conveying slider towards the inside of the equipment. The number of metal rods can be determined according to actual needs. To balance processing speed and quality, this invention uses three metal rods, which ensures efficient processing of finished products and avoids making the equipment too large due to processing too much material at once. The conveying slider is positioned vertically above... A first cylinder is provided, and a second cylinder is connected to the piston of the first cylinder. A first clamp that can move laterally in a staggered manner is connected to the second cylinder. The first clamp extends downward to form multiple first clamping parts, which are respectively located on both sides of the metal rod. Driven by the second cylinder, the clamping parts can move laterally in a staggered manner to press the metal rod. The function of the first cylinder is to drive the second cylinder on its piston. The second cylinder can move along the axial direction of the metal rod, and its lateral movement distance can be adjusted according to the length of the wax tube. When the length of the wax tube is short, the movement length of the first cylinder is increased. The clamp connected to the second metal rod is used to clamp the wax tube onto the metal rod after it is fitted onto the metal rod, so as to prevent the wax tube from falling off during transportation.
[0007] The ash tube feeding mechanism includes a hopper, a third cylinder, and a fourth cylinder. A side plate on one side of the hopper extends downwards, and a third cylinder is longitudinally fixed below the hopper. The third cylinder is attached to the side plate, and a lifting plate is fixedly connected to the piston of the third cylinder. The top of the lifting plate has a lifting surface for lifting the ash tubes. When the side plate is at the bottom, the tubes will accumulate in the lifting surface of the side plate. When the lifting surface rises, one tube will be lifted out from the innermost side of the lifting surface, and other tubes will fall out of the included angle of the lifting surface, thus realizing the lifting process of a single tube. The top surface of the side plate has a positioning groove, which is a recessed groove. When the side plate is lifted to the top, the tube will fall into the positioning groove and be fixed in the positioning groove by the simultaneous action of the side plate and the positioning groove. The fourth cylinder is horizontally arranged above the hopper, and the fourth cylinder and the positioning groove are arranged on the same axis. The number of the white wax tube feeding mechanism is greater than one, and the white wax tube feeding mechanisms are all fixed at the same horizontal height and arranged in an alternating manner.
[0008] The heat shrink tubing heating mechanism includes a cylinder fixing block, on which a twelfth and thirteenth cylinder are arranged longitudinally. An upper heating clamp is connected to the piston of the twelfth cylinder, and a lower heating clamp is connected to the thirteenth cylinder. Semi-circular heating grooves are engraved at corresponding positions on the opposite surfaces of the upper and lower heating clamps. Heating devices are also installed inside the upper and lower heating clamps. The position of the heating grooves of the heating clamps corresponds to the position of the metal rod on the conveying mechanism. After the conveying mechanism transports the wax tubing fitted with heat shrink tubing laterally to the heating mechanism, the material is pushed forward into the heating device by a second electric cylinder. The upper and lower heating clamps of the heating device close, locking the metal rod and its sleeve in the heating groove, thereby achieving the heating and shrinking of the heat shrink tubing.
[0009] The single vibrator includes a base, a vibration generator, and multiple feeding tubes. The vibration generator is fixed on the base, and the feeding tubes are arranged parallel to each other on the vibration generator. The feeding tubes and the positioning grooves are respectively arranged on the same axis. The wax tubes in the positioning grooves are pushed into the feeding tubes. Through the vibration of the single vibrator, the wax tubes in the feeding tubes are pushed in an orderly manner towards the conveying mechanism. When the conveying mechanism is in the rightmost position, the metal rod on it corresponds to the axis of the feeding tubes. When the conveying mechanism moves towards the feeding tubes driven by the second electric cylinder, the metal rod can be aligned with the wax tubes in the feeding tubes and the wax tubes are fitted onto the metal rod. The feeding tubes are provided with feeding tube openings at the top, and a fifth cylinder is provided above the feeding tube openings. A check block is fixed on the piston of the cylinder. The check block spans above all the openings of the feeding pipe. The discharge end of the feeding pipe is equipped with a sixth cylinder placed vertically and a seventh cylinder placed horizontally. A stop block that can move vertically is fixed on the piston of the sixth cylinder. A fixing clamp that can open and close vertically is provided on the seventh cylinder. The fixing clamp is equipped with a wax tube clamping groove for clamping the wax tube. The wax tube clamping groove corresponds to the position of the feeding pipe. When the fixing clamp is closed, the clamping groove will adjust the angle of the wax tube by narrowing the opening of the staggered position so that it is aligned with the metal rod and can be smoothly fitted onto the metal rod. The check block can prevent the wax tube from being pushed back when it touches the rod. When the conveying mechanism is not in the single vibrator position, the stop block is used to block the discharge port of the feeding pipe to prevent the wax tube in the feeding pipe from falling out.
[0010] The raw materials for heat shrink tubing are usually delivered in rolls, so continuous feeding is required. The heat shrink tubing feeding mechanism includes a one-way roller, multiple rollers, and a support frame. The one-way roller is fixed inside the support frame. To prevent the heat shrink tubing from retracting and causing feeding failure, the one-way roller has low rotational resistance in the feeding direction and high resistance in the reverse rotation. At the same time, to improve the feeding stability of the heat shrink tubing, the rollers are provided with patterns to increase resistance and prevent the rollers from pressing against the one-way roller. An equal number of adjusting blocks for adjusting the height of the rollers are also fixed above the support frame. Multiple heat shrink tubings pass through the gap between the one-way roller and the rollers and extend to the cutting sleeve mechanism.
[0011] The heat shrink tubing cutting mechanism includes a heat shrink tubing pull-out device, a heat shrink tubing cutting device, and a heat shrink tubing insertion clamp. The heat shrink tubing pull-out device includes a third electric cylinder with its bottom longitudinally fixed to the worktable and a cylinder support that can slide along the third electric cylinder. An eighth cylinder and a ninth cylinder are longitudinally arranged on one side of the cylinder support. The piston of the eighth cylinder passes laterally through the cylinder support and connects to a second upper clamp. The piston of the ninth cylinder passes laterally through the cylinder support and connects to a second lower clamp. The second upper clamp and the second lower clamp are housed in a clamp box. The clamp box has a tube-through hole on its side, which is located on the same longitudinal axis as the roller. The second upper clamp and the second lower clamp extend towards the middle to form a second clamping part, which corresponds to the position of the tube-through hole. The function of the heat shrink tubing pull-out device is to clamp the heat shrink tubing that has passed through the roller and then pull it to the opening of the heat shrink tubing tube-through clamp. After the heat shrink tubing cutting device separates, the heat shrink tubing pull-out device clamps the heat shrink tubing and moves along the slide rail of the third electric cylinder. When the heat shrink tubing reaches the corresponding position, the second clamping part is driven by the cylinder to separate left and right. Release the clamp on the heat shrink tubing and return it to the initial position. During this period, the heat shrink tubing remains in the state of passing through the tubing hole. The heat shrink tubing cutting device includes a vertically placed fourth electric cylinder and upper and lower cutters that can move vertically along the fourth electric cylinder. The upper and lower cutters are longitudinally aligned and can move alternately. After the heat shrink tubing completes its stretching motion and returns to the initial position, the cutters will cut the heat shrink tubing between the heat shrink tubing pull-out device and the heat shrink tubing clamp, thereby ensuring that the heat shrink tubing passing through the heat shrink tubing pull-out device will not break. The heat shrink tubing clamp includes a third upper clamp and a third lower clamp made of multiple layers of metal sheets. Both the third upper clamp and the third lower clamp are provided with positioning slots for positioning the heat shrink tubing. The third upper clamp is fixed to the piston of the tenth cylinder, and the third lower clamp is fixed to the piston of the eleventh cylinder. When the positioning slots are closed, they can clamp the heat shrink tubing tightly. The staggered and overlapping structure of the multiple metal sheets can support the heat shrink tubing held in it into a circle, and can also increase the friction between the upper and lower clamps and the heat shrink tubing, so as to prevent the heat shrink tubing from falling off during the tubing insertion process.
[0012] The feeding mechanism includes a feeding clamp assembly and a discharge chute. The feeding clamp assembly includes a fifth electric cylinder, which is horizontally placed on an electric cylinder support frame. The fifth electric cylinder has a feeding slider that can slide along it. The feeding slider has a fourteenth cylinder and a sixteenth cylinder. The sixteenth cylinder is placed vertically, and the fourteenth cylinder is fixed to the piston of the sixteenth cylinder and can move up and down with the piston of the sixteenth cylinder. A fourth clamp is connected to the piston of the fourteenth cylinder. The fourth clamping part extends downward to form a fourth clamping part. The gaps between the fourth clamping parts correspond to the positions of the heating tanks. The discharge trough and the unloading clamping assembly are located on the same horizontal axis. The fourth clamp can clamp out the finished sleeve processed in the heat shrink tubing heating mechanism and transport the clamped sleeve to the discharge trough by following the movement of the unloading slider on the fifth electric cylinder. The discharge trough can be equipped with a conveyor belt mechanism to transfer the finished tube to the material box, or the structure of the discharge trough can be tilted downward to the material end, so that the sleeve in the discharge trough automatically rolls down to the next process.
[0013] The feeding clamp assembly also includes a feeding push plate, which is disposed in the discharge trough. The feeding push plate is fixed on the piston of the fifteenth cylinder. The feeding push plate can move up and down with the drive of the fifteenth cylinder. The fifteenth cylinder is connected to the feeding slider through a feeding connector. The feeding push plate can move laterally with the feeding slider. When the discharge trough is horizontal, by connecting a feeding push plate to the feeding slider, the sleeves accumulated in the discharge trough can be pushed to the next process position. The fifteenth cylinder can drive the push plate to move up and down. When the push plate moves outward, the cylinder lowers the push plate to push the tube. During the movement, the tubes held on the fourth clamp are placed in the discharge trough. To avoid the push plate hitting the newly placed tubes in the discharge trough during the return process, the fifteenth cylinder will lift it up during the return process to complete the return.
[0014] The beneficial effects of this invention are as follows: This equipment uses a set of conveying mechanisms to realize the feeding, conveying, heat shrinking, and sleeve processes of wax tubes and heat shrink tubing. At the same time, it can also send the sleeved tubing to the heating mechanism. The structure and principle are relatively simple. After the tube is placed into the heating device, the conveying mechanism starts a new cycle. The heat-shrinked tube is taken out and conveyed by the unloading mechanism. This two-step working mode can significantly reduce the processing cycle time and effectively improve processing efficiency. The heating mechanism does not use a traditional hot air gun as a heating tool. Instead, the heating device is installed in the copper block mold. Compared with the hot air gun shrinkage, it can achieve all-round and uniform shrinkage at the same time, with good shrinkage effect and greatly shortened shrinkage time. Attached Figure Description

[0042] This invention provides two specific embodiments:
[0043] Example 1:
[0044] In the device shown in the figure, in order to balance the size of the device and the processing efficiency, the number of wax tube feeding mechanisms 1 is three. Therefore, the number of feeding tubes 63 on the single vibrator 6 is also three, as are the number of metal rods 54, the number of rollers 22 of the heat shrink tube feeding mechanism 2, and the number of heating grooves 36 of the heat shrink tube heating mechanism 3. The operator first places the wax tubes 16 cut to the same length into the hopper 11, hangs the rolled heat shrink tube behind the heat shrink tube feeding mechanism 2, and leads one end of it through the gap between the roller 22 and the one-way roller 21 and through the tube hole opened on the heat shrink tube pull-out device 71. In section 718, after the machine is turned on, it completes a self-inspection and begins processing: First, the conveying mechanism 5 moves to the initial position at the far right. During the rising process, the lifting plate 14 in the wax tube feeding mechanism 1 will bring the wax tube 16 stuck at its top lifting surface 15 upwards. When the lifting plate 14 rises to its highest point, it will be at the same horizontal height as the positioning groove 17. Under the supporting force of the lifting surface 15, the wax tube rolls into the positioning groove 17. In order to balance the size of the equipment and the processing efficiency, there are three wax tube feeding mechanisms 1, so the number of wax tubes 16 processed at the same time is also three. When the wax tube 16 rolls into the positioning groove... Afterwards, the fourth cylinder 18, located on the same axis as the positioning groove 17, pushes the wax tube 16 in the positioning groove 17 into the feeding pipe 63 of the single vibrator 6. The wax tube 16 in the single vibrator 6 will gradually move towards the conveying mechanism 5 as the single vibrator 6 vibrates. At the final discharge point of the feeding pipe 63, the outlet is blocked by the stop block 661 to prevent the wax tube 16 from falling out. After the conveying mechanism 5 is in place, the seventh cylinder 67 will drive the wax tube fixing clamp 671 to retract and clamp, accurately positioning the wax tube 16, which extends from the outlet of the feeding pipe 63, through the wax tube clamping groove 672. At this time, the metal rod 54 on the conveying mechanism 5 follows. The second electric cylinder 52 moves forward, while the sixth cylinder 66 drives the stop block 661 to descend and avoid the metal rod 54. The fifth cylinder 65 drives the check block 651 to descend and press against the opening 64 of the feeding pipe. This is to block the wax tube 16 and prevent it from retracting when it comes into contact with the metal rod 54, which would result in an unstable fit. After the metal rod 54 is inserted into the wax tube 16, the first cylinder 55 above the conveying slider 53 pushes the second cylinder 56 forward, so that the first clamp 57 connected to the second cylinder 56 moves to both ends of the wax tube 16 and clamps it on the metal rod 54 to prevent the wax tube 16 from shifting position or falling off during the conveying process.
[0045] During the feeding process of the wax tube 16, the heat shrink tubing pull-out device 71 clamps the heat shrink tubing inserted therein and moves along the fourth electric cylinder 721 to stretch the end of the heat shrink tubing into the heat shrink tubing insertion clamp 73. The heat shrink tubing insertion clamp 73 closes to clamp the heat shrink tubing. Then, the second clamping part in the heat shrink tubing pull-out device 71 releases and returns to the initial position along the fourth electric cylinder 721. During this process, the heat shrink tubing remains in the state of passing through the insertion hole 718. When the heat shrink tubing pull-out device 71 returns to the initial position... After positioning, the fourth electric cylinder 721 of the heat shrink tubing cutting device 72 drives the upper cutter 722 and the lower cutter 723 to cut the heat shrink tubing in the middle. At this time, the metal rod 54 with the fitted wax tube 16 moves laterally to the corresponding position and inserts the wax tube 16 into the heat shrink tubing. At the same time, the first clamp 57 connected to the second cylinder 56 above the conveying slider 53 first loosens and then clamps, clamping the wax tube 16 and the heat shrink tubing at the same time and maintaining their relative positions, and then transferring them to the heat shrink tubing heating mechanism 3.
[0046] After the conveying mechanism 5 moves laterally to the corresponding position of the heating mechanism, the position of the metal rod 54 will match the position of the heating groove 36. After the upper heating clamp 34 and the lower heating clamp 35 merge, the heat shrink tube will be clamped in the heat shrink groove 36 to heat the heat shrink tube. At the same time, the first clamp 57 is released, the conveying slider 53 retracts, and the fourth clamp 415 clamps. At this time, the conveying mechanism 5 returns to the initial position to realize a new cycle of work. The fourth clamp 415 moves the finished sleeve in the heating groove 36 laterally to the discharge groove 42. During the lateral movement, the unloading push plate 417 moves laterally to the bottom state. Its purpose is to push the finished sleeve placed in the discharge groove 42 by the fourth clamp 415 out of the discharge groove 42. During the return to the original position, the unloading push plate 417 is driven upward by the fifteenth cylinder 418 to avoid pushing the finished sleeve just placed in the discharge groove 42 back into the machine. Thus, the device described in this invention completes a complete work cycle and starts a new cycle.
[0047] Example 2:
[0048] Since the raw material for the wax tube 16 is wax tube segments cut to the same length, to avoid unqualified situations where the wax tube 16 is too long or too short, it is necessary to monitor the length of the wax tube 16 and reject those that do not meet the length requirements. To achieve this, in this embodiment, photoelectric switches are respectively installed on the check block 651 above the three feeding pipe openings 64. When the wax tube 16 passes through the feeding pipe opening 64, the photoelectric switch measures the length of the wax tube 16. If there is a wax tube 16 whose length does not meet the preset requirement, its position on the feeding pipe 63 will be recorded for subsequent rejection. The second electric current of the conveying mechanism 5 will then be activated. A blower controller 58 is installed next to cylinder 52, and multiple blower pipes 581 are led out. The opening of the blower pipe 581 is fixed to the fixed end of metal rod 54. If the length of the wax tube 16 does not meet the predetermined required length, after the conveying mechanism 5 has completed the sleeve, it will move the sleeved material tube from the sleeve cutting mechanism 7 to the heat shrink tube heating mechanism 3. Before the heat shrink tube is heated and shrunk, the first clamp 57 will loosen the sleeved tube on the metal rod 54. The blower controller 58 will be driven to start, blowing the tube with the unqualified length from the metal rod 54, so as to avoid the unqualified tube material being mixed into the qualified finished product and reducing the product qualification rate.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
