Description

Technical Field

[0001] This invention relates to the technical field of electronic device manufacturing, and in particular to a heat shrink tubing forming machine for electronic devices. Background Technology

[0002] Currently, some electronic components (such as capacitors) require adhesive tape (such as labels) to be applied to their top surface and precisely fitted onto heat shrink tubing. Existing technology typically involves manual operation: the tape is applied manually to the top surface of the component, a small section of heat shrink tubing is manually inserted, and then a heat gun is used to firmly wrap the tubing around the component's outer wall. This manual method is inefficient and cannot achieve consistent quality, failing to meet the demands of high-efficiency, high-quality electronic component production. Summary of the Invention

[0003] The purpose of this invention is to provide a heat shrink tubing forming machine for electronic devices, which mainly solves the technical problem of how to automatically apply adhesive tape and heat shrink tubing to electronic devices.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0006] The turntable is rotatable relative to the frame, and the turntable is provided with a clamp for clamping electronic devices. When the turntable rotates, it drives the clamp to rotate relative to the frame.

[0007] The feeding mechanism is used to automatically supply electronic components; the loading mechanism is located on one side of the feeding mechanism and is used to transfer the electronic components on the feeding mechanism to the clamps on the turntable; the adhesive paper feeding mechanism is used to automatically supply adhesive paper.

[0008] The adhesive applicator, the sleeve mechanism, the calibration mechanism, the heat shrink mechanism, and the unloading mechanism are arranged sequentially along the rotation direction of the turntable on one side of the turntable. The adhesive applicator is used to automatically apply the adhesive paper located on the adhesive paper supply mechanism to the top surface of the electronic device located on the fixture. The sleeve mechanism is used to fit the heat shrink sleeve onto the electronic device located on the fixture. The calibration mechanism is used to calibrate the position of the heat shrink sleeve fitted on the electronic device. The heat shrink mechanism is used to heat shrink the heat shrink sleeve and wrap it around the outer wall of the electronic device.

When the dial wheel rotates, the protrusions are embedded in the holes of the tape to drive the tape to move in the guide groove. The movement path of the tape includes a position adjacent to the feeding mechanism.

[0016] The heat shrink tubing forming machine for electronic devices also includes a cutting mechanism connected to the frame. The cutting mechanism is located on one side of the dial and is used to cut off the pins of the electronic device so that the pins of the electronic device can be separated from the tape.

[0018] The shaft is axially oriented vertically and is used to open the inner hole of the heat shrink tubing.

[0019] The sleeve module includes adjacently arranged receiving posts and a pushing assembly. The receiving posts are slidably connected to the mounting base in the vertical direction, and the receiving posts are located directly above the shaft core.

[0020] The first gripper is connected to the frame and is located directly above the second gripper. Both the first gripper and the second gripper are used to simultaneously grip the heat shrink tubing and the shaft core inside the heat shrink tubing.

[0021] The first driver is connected to the frame and the second gripper respectively. The first driver is used to drive the second gripper to move in the vertical direction.

[0026] In the above technical solution, the shaft core includes an inner core and an outer core. The outer core is sleeved on the outer wall of the inner core and can slide freely in the vertical direction relative to the inner core. The outer diameter of the top of the inner core is larger than the outer diameter of the outer core. An elastic element is provided between the inner core and the outer core.

The material includes a material belt and multiple adhesive strips adhered to the material belt. The peeling blade is connected to the base. The peeling blade is located adjacent to the bend of the material belt and is used to peel off the adhesive strips.

[0029] In the above technical solution, the calibration mechanism includes a connected actuator and a pressing block; the actuator is used to drive the pressing block to move in the vertical direction, and the pressing block is used to push the heat shrink tubing sleeved on the electronic device to move downward to a predetermined position.

[0030] Compared with the prior art, the present invention provides at least the following beneficial effects:

[0031] During operation, the feeding mechanism automatically feeds electronic components, and then the loading mechanism moves the electronic components from the feeding mechanism to the fixture on the turntable. Then, the rotation of the turntable moves the fixture sequentially to the adjacent positions of the adhesive application mechanism, the sleeve mechanism, the calibration mechanism, the heat shrink mechanism, and the unloading mechanism. The adhesive application mechanism is used to automatically apply the adhesive paper located on the adhesive paper supply mechanism to the top surface of the electronic components. The sleeve mechanism is used to automatically insert the heat shrink sleeve onto the electronic components. After the heat shrink sleeve is in place, the calibration mechanism calibrates the position of the heat shrink sleeve on the electronic components. Then, the heat shrink mechanism blows hot air onto the heat shrink sleeve, so that the heat shrink sleeve is heated and wraps around the outer wall of the electronic components. Finally, the unloading mechanism unloads the electronic components that have completed the adhesive application and sleeve operation from the fixture to the preset position.

[0032] In summary, this solution can automatically apply adhesive and precisely fit heat shrink tubing onto electronic components, significantly improving the tubing efficiency and ultimately increasing the production efficiency of electronic components. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0062] Please refer to the following: Figures 1 to 3 This embodiment provides a heat shrink tubing forming machine for electronic devices, including a frame 1 and a feeding mechanism 2, a cutting mechanism 3, a turntable 4, a loading mechanism 5, a tubing mechanism 6, a calibration mechanism 7, a heat shrinking mechanism 8, an adhesive paper feeding mechanism 9, a unloading mechanism 10, and an adhesive application mechanism 11, all connected to the frame 1. The turntable 4 is driven by a motor, allowing it to rotate relative to the frame 1. A clamp 41 is mounted on the turntable 4. The loading mechanism 5, adhesive application mechanism 11, tubing mechanism 6, calibration mechanism 7, heat shrinking mechanism 8, and unloading mechanism 10 are sequentially arranged on one side of the turntable 4 along its rotation direction.

[0063] Specifically, the feeding mechanism 2 uses a tape 24 to automatically feed the electronic device 90. The tape 24 is used to bond the pins of multiple electronic devices 90. At this time, simply driving the tape 24 to move the electronic device 90 can move it to the required position. The lead-cutting mechanism 3 is used to cut off the pins on the electronic device 90, so that the electronic device can be separated from the tape 24. After being separated from the tape 24, the electronic device 90 is placed on the fixture 41 under the drive of the loading mechanism 5. The turntable 4 drives the fixture 41 to rotate, so that the fixture 41 is sequentially moved to the adjacent positions of the adhesive applicator 11, the sleeve mechanism 6, the calibration mechanism 7, the heat shrinking mechanism 8, and the unloading mechanism 10. The adhesive feeding mechanism 9 is used to automatically supply adhesive tape, the adhesive application mechanism 11 is used to automatically apply the adhesive tape on the adhesive feeding mechanism 9 to the top surface of the electronic device 90 on the fixture 41, the sleeve mechanism 6 is used to put the heat shrink sleeve onto the electronic device 90 on the fixture 41, the calibration mechanism 7 is used to calibrate the position of the heat shrink sleeve on the electronic device 90 so that the position of the heat shrink sleeve relative to the electronic device 90 is more accurate, the heat shrinking mechanism 8 uses hot air to heat shrink the heat shrink sleeve and make the heat shrink sleeve wrap the outer wall of the electronic device 90, and the unloading mechanism 10 is used to unload the electronic device 90 on the fixture 41 to a preset position.

[0064] The electronic device 90 in this embodiment takes a capacitor as an example. The following description, in conjunction with the accompanying drawings, will explain each of the above-mentioned mechanisms in detail.

[0065] Please refer to the following: Figures 4 to 6The feeding mechanism 2 includes a base 21, a drive motor 22, a turntable 23, and a tape feeder 24. The base 21 is fixed to the frame 1 and has a guide groove 211 for the tape feeder 24 to enter and exit. The guide groove 211 preferably extends in a U-shape, ensuring that the direction in which the tape feeder 24 enters the guide groove 211 is opposite to the direction in which it leaves the guide groove 211. The tape feeder 24 has multiple holes 241 along its length. The drive motor 23... 2. Fixed to the base 21, the dial wheel 23 is connected to the output shaft of the actuating motor 22. The dial wheel 23 has multiple protrusions 231 protruding from its radial outer wall. When the dial wheel 23 rotates under the drive of the actuating motor 22, the protrusions 231 of the dial wheel 23 will embed into the holes 241 of the tape 24, causing the tape 24 to move along the extension direction of the guide groove 211. The movement path of the tape 24 includes a position adjacent to the aforementioned feeding mechanism 5, allowing the feeding mechanism 5 to pick up the capacitor from the tape 24. The aforementioned lead-cutting mechanism 3 cuts off the capacitor leads by laterally driving the blade 31 to move laterally, separating the capacitor from the tape 24, thus allowing the feeding mechanism 5 to easily remove the capacitor from the tape 24. In reality, the cut leads on the capacitor will not fall downwards; they will remain on the tape 24 and be fed out along the guide groove 211.

[0066] Among them, the feeding mechanism 5 is a conventional two-axis or three-axis picking robot. The structure of the feeding mechanism 5 will not be described in detail here.

[0067] Please see Figure 3 Multiple clamps 41 are fixed on the turntable 4, which enables the feeding mechanism 5, the adhesive applicator 11, the sleeve mechanism 6, the calibration mechanism 7, the heat shrinking mechanism 8 and the unloading mechanism 10 to work simultaneously, thereby improving the working efficiency of the equipment.

[0068] Please refer to the following: Figure 7 and Figure 8 The adhesive feeding mechanism 9 includes a base 91, a peeling blade 92, a feeding roller 93, and a receiving roller 94. The base 91 is fixed to the frame 1. The feeding roller 93 and the receiving roller 94 are rotatably connected to the base 91. The feeding roller 93 feeds out material 95, and the receiving roller 94 collects the material 95. The material 95 includes a material belt 951 and multiple adhesive sheets 952 adhered to the material belt 951. The peeling blade 92 is fixedly connected to the base 91 and is positioned adjacent to the bend in the material belt 951's feeding position. It peels off the adhesive sheets 952, separating them from the material belt 951 so that the adhesive applicator 11 can easily remove the peeled adhesive sheets 952. The adhesive applicator 11 is a conventional two-axis or three-axis material handling robot; its structure will not be described in detail here.

[0069] In this embodiment, the outer dimensions of the adhesive tape 952 are larger than the outer dimensions of the top surface of the capacitor. In fact, after the adhesive tape 952 is applied to the top surface of the capacitor, it needs to be shaped so that it not only adheres to the top surface but also covers part of the capacitor's sidewalls. Therefore, this embodiment also includes a first shaping mechanism 12 and a second shaping mechanism 13. The adhesive application mechanism 11, the first shaping mechanism 12, the second shaping mechanism 13, and the sleeve mechanism 6 are sequentially arranged on one side of the turntable 4 along the rotation direction of the turntable 4. Through the sequential shaping of the adhesive tape 952 by the first shaping mechanism 12 and the second shaping mechanism 13, the adhesive tape 952 is not only applied to the top surface of the capacitor but also covers part of the capacitor's sidewalls.

[0070] Please see Figure 9 The first shaping mechanism 12 includes a longitudinal drive device 121, a gripper cylinder 122, a pressure block 123, and two clamping blocks 124. The longitudinal drive device 121 is mounted on the frame 1. The longitudinal drive device 121 is preferably a cylinder. The gripper cylinder 122 is connected to the two clamping blocks 124 and is used to drive the two clamping blocks 124 to move closer to each other or further away from each other. The pressure block 123 is fixedly connected to the cylinder body of the gripper cylinder 122 and extends between the two clamping blocks 124. The longitudinal drive device 121 is connected to the gripper cylinder 122 and is used to drive the gripper cylinder 122, the pressure block 123, and the two clamping blocks 124 to move together in the vertical direction. During operation, the capacitor is driven by the turntable 4 to the position directly below the pressure block 123. At this position, the two clamping blocks 124 are in the open state. Then, the longitudinal drive device 121 drives the gripper cylinder 122, the pressure block 123, and the two clamping blocks 124 to move downward together, so that the pressure block 123 presses the top surface of the capacitor through the adhesive paper 952 to stabilize the position of the capacitor. At the same time, as the two clamping blocks 124 move downward, they push the outer ring of the adhesive paper 952 to bend downward. Finally, the gripper cylinder 122 drives the two clamping blocks 124 to move closer to each other, and the two clamping blocks 124 together clamp the side wall of the capacitor, so that the outer ring of the adhesive paper 952 is adhered to the side wall of the capacitor.

[0071] Please refer to the following: Figure 10 and Figure 11The second shaping mechanism 13 includes a longitudinal drive module 131, a gripper driver 132, a pressure head 133, and two clamping blocks 134. The longitudinal drive module 131 is mounted on the frame 1. The longitudinal drive module 131 is preferably a lead screw module. The gripper driver 132 is connected to the two clamping blocks 134 and is used to drive the two clamping blocks 134 to move closer or further apart. The pressure head 133 is connected to the gripper driver 132 and extends between the two clamping blocks 134. The longitudinal drive module 131 is connected to the gripper driver 132 and is used to drive the gripper driver 132, the pressure head 133, and the two clamping blocks 134 to move together in the vertical direction. When the two clamping blocks 134 move closer to each other, the two clamping blocks 134 and the outer side wall of the pressure head 133 together form an annular groove 135. The shape of the outer ring of the annular groove 135 is adapted to the shape of the outer side wall of the capacitor. During operation, the longitudinal drive module 131 drives the gripper driver 132, the pressure head 133, and the two clamping blocks 134 to descend together, so that the pressure head 133 presses against the top surface of the capacitor through the adhesive tape 952 to stabilize the position of the capacitor. At the same time, the two clamping blocks 134 descend to the sides of the capacitor. Finally, the gripper driver 132 drives the two clamping blocks 134 to move closer to each other. After the two clamping blocks 134 abut against the side wall of the capacitor, the longitudinal drive module 131 drives the gripper driver 132 and the two clamping blocks 134 to descend further. The two clamping blocks 134 straighten the adhesive tape 952 so that the adhesive tape 952 is tightly attached to the side wall of the capacitor.

[0072] Please refer to the following: Figures 12 to 14 The sleeve mechanism 6 includes a frame 61, a first driver 62, a first gripper 63, a second gripper 64, a shaft 65, a third driver 66, a cutter 67, a fourth driver 68, a mounting base 69, and at least one sleeve module 70.

[0073] The first actuator 62 includes a motor 621, a lead screw 622, a nut 623, a slide block 624, and a guide rail 625. The motor 621 is fixed to the frame 61. The lead screw 622 is rotatably connected to the frame 61, with its axis pointing vertically. The nut 623 is sleeved on the lead screw 622 and threadedly connected to it. The slide block 624 is fixedly connected to the nut 623. The guide rail 625 is fixed to the frame 61 and its length points vertically. The slide block 624 and the guide rail 625 are slidably connected vertically. The second gripper 64 is fixed to the slide block 624. During operation, the motor 621 drives the lead screw 622 to rotate, causing the nut 623 to move vertically upwards or downwards. This, in turn, causes the slide block 624 and the second gripper 64 to move vertically. The second gripper 64 is used to simultaneously grip the heat shrink tubing and the shaft core 65 inside the heat shrink tubing.

[0074] The first gripper 63 is positioned directly above the second gripper 64 and fixed to the frame 61. The first gripper 63 is also used to simultaneously grip the heat shrink tubing and the shaft core 65 inside the heat shrink tubing. Both the first gripper 63 and the second gripper 64 are gripper cylinders.

[0075] The shaft core 65 includes an inner core 651 and an outer core 652. The outer core 652 is sleeved on the outer wall of the inner core 651 and can slide freely in the vertical direction relative to the inner core 651. An elastic element 653 is provided between the inner core 651 and the outer core 652. The elastic element 653 is a compression spring. The outer core 652 has a downward sliding tendency due to the force of the elastic element 653. The first gripper 63 is used to simultaneously grip the heat shrink tubing and the top end of the inner core 651. The second gripper 64 is used to simultaneously grip the heat shrink tubing and the outer core 652.

[0076] The third actuator 66 is a dual-axis cylinder fixed on the frame 61. The third actuator 66 is connected to the cutter 67 and is used to drive the cutter 67 to extend into the outer core 652.

[0077] The fourth actuator 68 is a rotary cylinder, and two sleeve modules 70 are mounted on the mounting base 69. The fourth actuator 68 drives the mounting base 69 and the two sleeve modules 70 to rotate together, so that the positions of the two sleeve modules 70 are exchanged.

[0078] Specifically, the sleeve module 70 includes a receiving post 701 and a pushing assembly 702 arranged adjacent to each other. The pushing assembly 702 includes a connected fifth driver 7021 and a pushing member 7022. The fifth driver 7021 is fixed on the mounting base 69, and the pushing member 7022 is sleeved on the outer wall of the receiving post 701. The fifth driver 7021 drives the pushing member 7022 to slide along the axial direction of the receiving post 701, while the receiving post 701 is slidably connected to the mounting base 69 in the vertical direction. The receiving post 701 is located directly above the shaft core 65. The receiving post 701 is used to receive the heat shrink sleeve that is sleeved upward from the shaft core 65. When the fifth driver 7021 drives the pushing member 7022 to slide downward, the pushing member 7022 pushes the heat shrink sleeve sleeved on the receiving post 701 downward. In addition, a sixth actuator 611 is fixed on the frame 61. A spring 703 is sleeved on the outer wall of the receiving column 701. The sixth actuator 611 is a cylinder. The sixth actuator 611 is used to drive the receiving column 701 to move downward. When the receiving column 701 moves downward, it will further compress the spring 703. When the sixth actuator 611 resets, the receiving column 701 moves upward to the reset position under the force of the spring 703.

[0079] The working principle of the sleeve mechanism 6 in this scheme can be summarized as follows:

[0080] The heat shrink tubing is pre-inserted onto the shaft core 65 from bottom to top, so that the shaft core 65 is located inside the inner hole of the heat shrink tubing. At this time, the shaft core 65 pushes the originally flat heat shrink tubing outward.

[0081] During operation, the first gripper 63 simultaneously holds the heat shrink tubing and the inner core 651 of the shaft core 65. Then, the sixth actuator 611 drives the receiving post 701 to descend, causing it to abut against the top surface of the shaft core 65. Next, the second gripper 64 simultaneously holds the heat shrink tubing and the outer core 652 of the shaft core 65. Immediately afterward, the first gripper 63 switches to the open state, and the second gripper 64 moves upward under the drive of the first actuator 62, causing the heat shrink tubing held by the second gripper 64 to move upward along the shaft core 65 and fit onto the receiving post 701 (at this time, the outer core 652 moves upward along with the heat shrink tubing under the grip of the second gripper 64). Then, the first gripper 63 again simultaneously holds the heat shrink tubing and the inner core 651 of the shaft core 65. Then, the sixth actuator 611... 1. The device moves upward to reset. At this time, the receiving post 701 rises a short distance under the action of the spring 703. Then, the third driver 66 drives the cutter 67 to extend between the receiving post 701 and the shaft core 65 to cut the heat shrink tubing, so that the receiving post 701 has a small section of heat shrink tubing. Finally, the fourth driver 68 drives the two tubing modules 70 to rotate 180°, so that the receiving post 701 of one tubing module 70 continues to receive the heat shrink tubing that is pushed upward from the shaft core 65, while the other tubing module 70 is located directly above the capacitor. The fifth driver 7021 in the tubing module 70 drives the pusher 7022 to move downward. The pusher 7022 pushes the small section of heat shrink tubing on the receiving post 701 downward, so that the small section of heat shrink tubing is finally put on the capacitor.

[0082] In fact, the stroke of the first actuator 62 controls the depth to which the heat shrink tubing is inserted into the receiving post 701, and the stroke of the fifth actuator 7021 controls the depth to which the heat shrink tubing is inserted into the capacitor. Moreover, this technical solution is more suitable for situations where small-diameter heat shrink tubing requires appropriate enlargement. Therefore, the outer diameter of the top of the inner core 651 is slightly larger than the outer diameter of the outer core 652, while the outer diameter of the receiving post 701 is equal to or slightly smaller than the outer diameter of the top of the inner core 651.

[0083] Please see Figure 15 The calibration mechanism 7 includes a connected actuator 71 and a pressing block 72. The actuator 71 is used to drive the pressing block 72 to move in the vertical direction. The pressing block 72 is used to push the heat shrink tubing sleeved on the capacitor downward, and finally make the top surface of the heat shrink tubing flush with the top surface of the capacitor.

[0084] The heat shrink mechanism 8 in this embodiment is prior art. The heat shrink mechanism 8 uses hot air to blow onto the capacitor located on the clamp 41 to wrap the heat shrink sleeve 90 around the outer wall of the capacitor. Therefore, this embodiment will not describe the heat shrink mechanism 8 in detail. To improve work efficiency, there are two heat shrink mechanisms 8. By heat shrinking the capacitor twice, it does not affect the simultaneous operation of other mechanisms.

[0085] The unloading mechanism 10 in this embodiment is a conventional two-axis or three-axis picking robot, and its structure will not be described in detail here. The unloading mechanism 10 transfers the capacitors on the clamp 41 to the material tray, and finally collects the finished capacitors by means of the material tray.

[0086] In summary, this solution can automatically apply adhesive and precisely fit heat shrink tubing onto electronic components 90, which can significantly improve the tubing efficiency of electronic components 90 and ultimately improve the production efficiency of electronic components 90.

[0087] The above are merely preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present invention.
