To address this, we propose a thermoforming device for optical cable clips. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a clip thermoforming device for optical cables, comprising a base plate supporting the entire device, wherein a plurality of arrayed lower molds are fixedly connected to the upper surface of the base plate near one side, and a corresponding upper mold is provided above each lower mold, wherein the top of the plurality of upper molds is fixedly connected to the same assembly plate, and a connecting rod that is driven to move up and down is fixedly connected to the upper surface of the assembly plate, wherein a plastic sheet is placed between the lower molds and the upper molds, and air holes are provided at the bottom of the upper molds and the bottom of the inner wall of the lower molds;

[0005] A gas guide pipe is fixedly connected to the lower surface of the base plate near the lower mold. The gas guide pipe passes through the base plate and communicates with the gas of the lower mold distributed in an array.

[0006] The upper surface of the assembly plate is penetrated and fixedly connected to a second air guide pipe, which communicates with multiple upper mold gases on the assembly plate after penetrating the assembly plate.

[0007] Preferably, a limiting plate is axially slidably connected through the arcuate contour of the first connecting rod, and the limiting plate is fixedly connected through the vertical section of the first air duct.

[0008] Preferably, a cutting device is provided on the upper part of the base plate away from the lower mold. The cutting device includes a separation cover set above the plastic sheet. An electric heating wire is fixedly connected to the lower edge of the separation cover near the collecting plate. A shrink rod is fixedly connected to the upper surface of the separation cover. A sleeve is slidably connected through the shrink rod and axially. A compression spring is provided inside the sleeve to reset the shrink rod after it is compressed.

[0009] A calibration ring is fixedly connected to the top of the sleeve, and a transmission ring is coaxially rotatably connected to the rear side of the calibration ring. A swing arm is rotatably connected to the inner edge of the transmission ring via a pin. A drive shaft driven by a power mechanism is fixedly connected to the surface of the swing arm at the end away from the transmission ring.

[0010] Preferably, two symmetrical pulling arms are fixedly connected to the upper surface of the separation cover near the collection plate. A second retractable rod is axially penetrated and slidably connected to one end of the pulling arm away from the separation cover. A second compression spring is provided in the vertical section of the pulling arm through which the second retractable rod penetrates. A camera for capturing images of the thermoformed buckle is fixedly connected to the bottom of the second retractable rod.

[0011] Preferably, the transmission ring has an arc-shaped profile near the assembly plate with a pneumatic module that pneumatically cooperates with the first and second air pipes, and the pneumatic module has a transmission component that controls the movement of the first connecting rod.

[0012] Preferably, the pneumatic module includes an air collecting cylinder fixedly supported by an external bracket. Both ends of the air collecting cylinder are axially limited and slidably connected by the same connecting rod two. A piston plate is fixedly connected through the arc-shaped contour of the connecting rod two. The surface of the piston plate is slidably connected to the inner wall of the air collecting cylinder. A filter screen is fixedly connected through the arc-shaped contour of the air collecting cylinder. The end of the filter screen away from the air collecting cylinder is fixedly connected to the end of the air guide pipe one away from the lower mold. The end of the air guide pipe two away from the collecting plate passes through the air collecting cylinder and is fixedly connected to the air collecting cylinder.

[0013] Preferably, the transmission assembly includes a steering ball fixed to one end of the connecting rod, a hemispherical cover is fitted on the arc-shaped contour of the steering ball, a fixed connecting rod is fixedly connected to the arc-shaped contour of the hemispherical cover, and the end of the fixed connecting rod away from the hemispherical cover is fixedly connected to the arc-shaped contour of the transmission ring.

[0014] Preferably, the transmission assembly further includes a steering ball two fixed to the other end of the connecting rod two, a hemispherical cover two fitted on the arc-shaped contour of the steering ball two, a connecting rod three connected to the arc-shaped contour of the hemispherical cover two, and the bottom of the connecting rod three being rotatably connected to the top of the connecting rod one by a pin.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The lower mold of this invention is a cup structure with an internal cavity, open upwards. The upper mold is a solid cup structure, also open upwards. Both the lower and upper molds are equipped with electric heating wires. When the plastic sheet is placed between the lower and upper molds, the upper mold moves downwards to feed the plastic sheet into the lower mold. Through temperature conduction between the lower and upper molds, the plastic sheet softens and smoothly enters the lower mold. During this process, the second air duct supplies positive pressure air to the upper mold, and the first air duct supplies negative pressure air to the lower mold. With the cooperation of the two, the softened plastic sheet can fully fit into the cavity formed between the lower and upper molds, thereby ensuring the quality of the snap-fit ​​thermoforming. The assembly plate centrally drives the synchronous lifting and lowering of multiple upper molds, and the connecting rod is driven by power to drive the synchronous lifting and lowering of the assembly plate.

[0017] After thermoforming, heating of the lower and upper molds is stopped. At this time, the gas flow direction in air duct one and air duct two is changed, allowing the upper mold, which previously applied positive pressure to the plastic sheet, to apply negative pressure to the plastic sheet through its pores. Similarly, the lower mold, which previously applied negative pressure to the plastic sheet, now applies positive pressure to the plastic sheet, allowing the thermoformed plastic sheet to be pulled upward smoothly from the lower mold. After the pressure is balanced and the plastic sheet is subjected to its own weight, it can be easily detached from the upper mold. In actual use, a cooling process is applied to the plastic sheet after thermoforming to make the detachment of the plastic sheet even more convenient.

[0018] The limiting plate is fixed to the vertical section of the air duct, thus securing the linkage. The limiting plate restricts the movement trajectory of the linkage, ensuring stable lifting and lowering motion.

[0019] The thermoformed portions of the plastic sheet are cut and grouped into sets of 16 for transfer. The separation hood, equipped with heating wires, rapidly melts the plastic sheet at high temperatures upon contact, allowing for group separation. The separation hood reciprocates vertically via a sleeve and a retraction rod. The retraction rod, sleeve, and internal spring extend the horizontal contact time between the heating wires and the plastic sheet, ensuring thorough separation. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1 to 3 The present invention provides a technical solution: a clip thermoforming device for optical cables, including a base plate 1 that supports the entire device. Multiple arrayed lower molds 2 are fixedly connected to the upper surface of the base plate 1 near one side. Each lower mold 2 is provided with a corresponding upper mold 3 above it. The top of the multiple upper molds 3 is fixedly connected to the same assembly plate 4. A connecting rod 5 that is driven to move up and down is fixedly connected to the upper surface of the assembly plate 4. A plastic sheet 6 is placed between the lower molds 2 and the upper molds 3. Air holes are opened at the bottom of the upper molds 3 and the bottom of the inner wall of the lower molds 2.

[0032] A gas guide pipe 7 is connected to the lower surface of the base plate 1 near the lower mold 2. The gas guide pipe 7 passes through the base plate 1 and communicates with the gas of the arrayed lower mold 2.

[0033] The upper surface of the assembly plate 4 is penetrated and fixedly connected to a second air guide pipe 8, which communicates with the gas of multiple upper molds 3 on the assembly plate 4 after penetrating the assembly plate 4.

[0034] The base plate 1 provides fixed support for the entire equipment. In actual use, multiple support frames are installed on the base plate 1. The support frames are existing technologies well known to those skilled in the art, and therefore are not shown in the figure.

[0035] The lower mold 2 is a cup structure with an internal cavity, open upwards. The upper mold 3 is a solid cup structure, also open upwards. Both the lower mold 2 and the upper mold 3 are equipped with electric heating wires. When the plastic sheet 6 is placed between the lower mold 2 and the upper mold 3, the upper mold 3 moves downwards, allowing the plastic sheet 6 to be fed into the lower mold 2. Through temperature conduction between the lower mold 2 and the upper mold 3, the plastic sheet 6 softens and smoothly enters the lower mold 2. During this process, the second air pipe 8 supplies positive pressure air to the upper mold 3, and the first air pipe 7 supplies negative pressure air to the lower mold 2. With the cooperation of the two, the softened plastic sheet 6 can fully fit into the cavity formed between the lower mold 2 and the upper mold 3, thereby ensuring the quality of the snap-fit ​​thermoforming.

[0036] The assembly plate 4 centrally drives the synchronous lifting and lowering of multiple upper molds 3, and the connecting rod 5 is driven by power to drive the synchronous lifting and lowering of the assembly plate 4.

[0037] Specifically, the positive pressure on the upper mold 3 and the negative pressure on the lower mold 2 are both connected by air holes on the lower mold 2 and the upper mold 3.

[0038] After thermoforming, heating of the lower mold 2 and upper mold 3 is stopped. At this time, the gas conduction direction in the air duct 1 7 and air duct 2 8 is changed, so that the upper mold 3, which originally applied positive pressure to the plastic sheet 6, can now apply negative pressure to the plastic sheet 6 through its air pores. Similarly, the lower mold 2, which originally applied negative pressure to the plastic sheet 6, now applies positive pressure to the plastic sheet 6, so that the thermoformed plastic sheet 6 can be smoothly pulled upward from the lower mold 2. After the pressure is balanced and under the influence of the plastic sheet 6's own weight, the plastic sheet 6 can be smoothly dragged off the upper mold 3. In actual use, a cooling operation is applied to the plastic sheet 6 after thermoforming to make the removal of the plastic sheet 6 more convenient.

[0039] Furthermore, a limiting plate 16 is axially slidably connected through the arc-shaped contour of the connecting rod 5, and the limiting plate 16 is penetrated and fixedly connected by the vertical section of the air guide pipe 7.

[0040] The limiting plate 16 is fixed on the vertical section of the air duct 7, thus securing it. The limiting plate 16 restricts the movement trajectory of the connecting rod 5, ensuring that the connecting rod 5 can perform stable lifting and lowering movements.

[0041] Example 2: A cutting device is provided on the upper part of the base plate 1 away from the lower mold 2. The cutting device includes a separation cover 9 set above the plastic sheet 6. An electric heating wire is fixedly connected to the lower edge of the separation cover 9 near the collecting plate 4. A shrink rod 10 is fixedly connected to the upper surface of the separation cover 9. A sleeve 11 is slidably connected through the shrink rod 10 and axially. A compression spring is provided inside the sleeve 11 to reset the shrink rod 10 after it is compressed.

[0042] A calibration ring 12 is fixedly connected to the top of the sleeve 11. A transmission ring 13 is coaxially rotatably connected to the rear side of the calibration ring 12. A swing arm 14 is rotatably connected to the inner edge of the transmission ring 13 via a pin. An active shaft 15 driven by a power mechanism is fixedly connected to the surface of the swing arm 14 away from the transmission ring 13.

[0043] refer to Figures 1-3 The thermoformed portion of the plastic sheet 6 is cut and grouped into sets of 16 for transfer. The separation cover 9, equipped with an electric heating wire, rapidly melts the plastic sheet 6 upon contact with it, allowing for group separation. The sleeve 11 and the retractable rod 10 drive the separation cover 9 to move vertically up and down. The retractable rod 10, sleeve 11, and the spring within the sleeve 11 extend the contact time between the electric heating wire on the separation cover 9 and the plastic sheet 6 in the horizontal direction, ensuring thorough separation.

[0044] The power mechanism on the drive shaft 15 is a motor after the power is turned on. The rotation of the output shaft of the motor drives the rotation of the drive shaft 15. The drive shaft 15 drives the swing arm 14 to rotate around the axis of the drive shaft 15. Through the transmission ring 13 and the calibration ring 12, the calibration ring 12 at the end of the swing arm 14 draws a circle with the drive shaft 15 as the center and the swing arm 14 as the radius of rotation. Since the calibration ring 12 and the transmission ring 13 are connected by a fixed axis rotation, under the gravity of the separation cover 9, the retraction rod 10 and the sleeve 11, the separation cover 9 always faces downward in the above-mentioned circular trajectory, finally realizing the separation of the plastic sheet 6 in groups and pushing away the separated plastic sheet 6.

[0045] Furthermore, two symmetrical pulling arms 17 are fixedly connected to the upper surface of the separation cover 9 near the collection plate 4. The end of the pulling arm 17 away from the separation cover 9 is axially penetrated and slidably connected to a second retractable rod 18. A second compression spring is provided in the vertical section of the pulling arm 17 penetrated by the second retractable rod 18. A camera 19 for capturing images of the thermoformed buckle is fixedly connected to the bottom of the second retractable rod 18.

[0046] However, the traction arm 17 is fixed on the separation cover 9 and will rise and fall synchronously with the separation cover 9. During the descent, the camera 19 on the traction arm 17 will first enter the thermoformed plastic sheet 6 to capture images of the inner wall of the thermoformed plastic sheet 6, and transmit them to the background to analyze the current thermoforming quality in conjunction with visual algorithms.

[0047] Secondly, at the same time, the plastic sheet 6 cut by the cutting device and the plastic sheet 6 into which the camera 19 enters are not from the same group. Therefore, when the swing arm 14 rotates, causing the camera 19 to enter the plastic sheet 6, the camera 19 and the retraction rod 18 will subsequently remain inside the plastic sheet 6 for a longer period under the action of the compression spring 18. During the subsequent rotation of the swing arm 14, the resulting horizontal displacement will cause the retraction rod 18 and the camera 19 to pull the plastic sheet 6 according to... Figure 1 The material moves in the direction of the middle arrow, thereby shifting the subsequent plastic sheet 6, so that the next set of thermoformed and cut plastic sheets 6 are transferred to the bottom of the separation cover 9, achieving a precise and tight fit.

[0048] Furthermore, the transmission ring 13 has an arc-shaped profile near the collection plate 4 with a pneumatic module that pneumatically cooperates with the air guide pipe 7 and the air guide pipe 8. The pneumatic module has a transmission component that controls the movement of the connecting rod 5.

[0049] By setting the air pressure module, the positive and negative pressure in the air guide tube 7 and the air guide tube 8 can be switched, thereby achieving full bonding of the plastic sheet 6 and demolding operation.

[0050] The transmission components enable the adjustment of positive and negative pressure within the pneumatic module and subsequent demolding transmission operations.

[0051] Furthermore, the pneumatic module includes an air collecting cylinder 20 fixedly supported by an external bracket. Both ends of the air collecting cylinder 20 are axially limited and slidably connected by the same connecting rod 21. The arc-shaped contour of the connecting rod 21 is slidably connected to a piston plate 22. The surface of the piston plate 22 is slidably connected to the inner wall of the air collecting cylinder 20. A filter screen 23 is slidably connected to the arc-shaped contour of the air collecting cylinder 20. One end of the filter screen 23 away from the air collecting cylinder 20 is fixedly connected to the end of the air guide pipe 7 away from the lower mold 2. One end of the air guide pipe 8 away from the collecting plate 4 passes through the air collecting cylinder 20 and is fixedly connected to the air collecting cylinder 20.

[0052] refer to Figure 1 as well as Figure 2 The gas collecting cylinder 20 is penetrated and axially slid by the connecting rod 21. In actual use, a shaft sealing mechanism will be added to both ends of the gas collecting cylinder 20. The shaft sealing structure is a prior art well known to those skilled in the art, so it is not shown in the figure.

[0053] When the connecting rod 21 moves in the direction of arrow B, it will increase the pressure in the space on the left side of the air collecting cylinder 20, forming positive pressure. The positive pressure is then transmitted to the upper mold 3 through the air guide pipe 28. At this time, the upper mold 3, the plastic sheet 6 and the lower mold 2 are in contact. The positive pressure is transmitted between the upper mold 3 and the plastic sheet 6 through the air holes on the upper mold 3, causing the plastic sheet 6 to bulge downward.

[0054] At the same time, it will reduce the pressure in the space on the left side of the air collecting cylinder 20, forming a negative pressure. This negative pressure is transmitted through the air guide pipe 7, creating a negative pressure environment inside the lower mold 2. This will further draw the already bulging plastic sheet 6 downward, thereby achieving a full bonding effect and ultimately improving the quality of thermoforming.

[0055] After the above thermoforming operation is completed, the heating operation of the lower mold 2 and the upper mold 3 is stopped, and the connecting rod 21 begins to move in the direction of arrow A to reset. At this time, the positive and negative pressures of the left and right parts of the air collecting cylinder 20 are switched, and finally the above thermoformed plastic sheet 6 is pulled up and separated from the lower mold 2 by the negative pressure on the upper mold 3. Then, under the influence of the gravity of the plastic sheet 6 and the pulling influence of the pulling arm 17, the shrinking rod 2 18 and the camera 19, the plastic sheet 6 will be successfully separated from the adsorption of the upper mold 3.

[0056] The aforementioned filter 23 filters dust particles in the flowing gas, further improving the quality of thermoforming.

[0057] Furthermore, the transmission assembly includes a steering ball 24 fixed to one end of the connecting rod 21. A hemispherical cover 25 is fitted on the arc-shaped profile of the steering ball 24. A fixed connecting rod 26 is fixedly connected to the arc-shaped profile of the hemispherical cover 25. One end of the fixed connecting rod 26 away from the hemispherical cover 25 is fixedly connected to the arc-shaped profile of the transmission ring 13.

[0058] refer to Figure 2 The transmission ring 13 is fixedly connected to the end of the swing arm 14, so that the transmission ring 13 can perform the circular trajectory movement mentioned above. With the rotational cooperation of the hemispherical cover 25 and the steering ball 24, the connecting rod 21 is not disturbed by the vertical movement and can perform stable horizontal reciprocating movement, thereby realizing the horizontal reciprocating movement of the piston plate 22 in the gas collecting cylinder 20.

[0059] Furthermore, the transmission assembly also includes a steering ball 27 fixed to the other end of the connecting rod 21. A hemispherical cover 28 is fitted on the arc-shaped contour of the steering ball 27. A connecting rod 3 29 is connected to the arc-shaped contour of the hemispherical cover 28. The bottom of the connecting rod 3 29 is rotatably connected to the top of the connecting rod 5 through a pin.

[0060] refer to Figure 3 As the second connecting rod 21 moves horizontally back and forth, the second steering ball 27 moves horizontally back and forth synchronously. With the rotational cooperation of the second steering ball 27 and the second hemispherical cover 28, and the pin connection between the third connecting rod 29 and the first connecting rod 5, the horizontal back and forth movement of the second connecting rod 21 is transmitted to the first connecting rod 5 to realize the vertical back and forth movement of the first connecting rod 5, thereby realizing the lifting and lowering movement of the assembly plate 4 and the upper mold 3 as described above.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
