Description

Technical Field

[0001] This application relates to the field of cable production equipment, and in particular to an adjustable cable connector anti-collision device. Background Technology

[0002] Cable connectors are prone to breakage and collisions with inkjet printers after entering the production line. This is mainly due to the concentration of mechanical stress at the connector (such as insufficient tensile strength caused by sudden changes in material / thickness), dynamic impact loads (instantaneous tensile / compression caused by production line traction, bending or vibration), and dimensional and structural defects (such as irregular shape or excessive rigidity). High-speed operation of the production line, lack of obstacle avoidance design, and improper connector fixing will further aggravate the risk of collision, ultimately leading to equipment damage, production interruption and quality defects.

[0003] When printing on cables, the printhead of the printer is close to the cable. To prevent the cable connector from hitting the printer, a sensor is usually installed in front of the printer to detect the connector. When the sensor detects the connector, the printer stops printing and moves the printhead. However, if the sensor is damaged, the running cable will not be stopped in time, and the connector will still hit the printhead. Summary of the Invention

[0004] To address the technical problem of cable connectors entering the production line and impacting the inkjet printer, this application provides an adjustable cable connector anti-collision device.

[0005] The adjustable cable connector anti-collision device provided in this application adopts the following technical solution:

[0006] An adjustable cable connector anti-collision device includes a base plate located directly below the cable. An electric actuator is fixed to the base plate, and a connector is fixed to the electric actuator. A nozzle is connected to the upper side of the connector for connecting to an inkjet printer to achieve inkjet printing. A support frame and a support plate are fixed to the base plate. A vision sensor is installed on the support plate. A horizontal plate is fixed above the support frame. Two sliders are slidably mounted on the horizontal plate. Each slider has a sensing component that triggers the electric actuator when the slider moves outward. The two sliders are symmetrically distributed. A transmission component is provided between the sliders and the electric actuator. When the electric actuator moves upward, the two sliders separate. A first spring is provided on the outer side of each slider to push the two sliders closer together. An inclined plate is fixed to each of the two sliders, and the two inclined plates are symmetrical. The end with the larger opening distance between the two inclined plates is the cable entry direction.

[0007] By adopting the above technical solution, when the cable connector enters the production line, the vision sensor first detects the connector. At this time, the electric push rod will rise, lifting the printhead upwards on one hand, and separating the two sliders to the sides through the transmission component on the other hand, so that the connector will not rub or collide with the inclined plate. When the vision sensor malfunctions or the signal transmission fails, the cable connector passes through the inclined plate, separating the two inclined plates to the sides. At this time, the sensing component is triggered, causing the electric push rod to rise upwards, which can still lift the printhead upwards, preventing the connector from colliding with the printhead and protecting the inkjet printer.

[0008] Preferably, the transmission assembly includes a crossbar fixed to the upper end of the electric push rod, and an inclined extrusion block with inclined surfaces on both sides is fixed on the crossbar. The inclined extrusion block is located directly below the cross plate. A first sliding groove is opened on the cross plate, and a slider is slidably disposed in the first sliding groove. A long slot is opened at the bottom of the first sliding groove, and the upper end of the inclined extrusion block is inserted into the long slot, with the inclined surface abutting against the slider.

[0009] By adopting the above technical solution, when the electric actuator is lifted upward, the crossbar can drive the inclined extrusion block to be lifted upward, and the inclined surface separates the two sliders to both sides, thereby separating the two inclined plates and preventing the inclined plates from frequently rubbing against the joint.

[0010] Preferably, the bottom of the slider near the inclined extrusion block is provided with an installation groove, and a roller is rotatably arranged in the installation groove, with the roller abutting against the inclined surface of the inclined extrusion block.

[0011] By adopting the above technical solution, during the process of the inclined extrusion block extruding the slider, the roller can change the sliding friction between the two into rolling friction, reduce friction and friction loss, extend the service life of the equipment, and reduce noise.

[0012] Preferably, the bottom of the inclined extrusion block is fixed with a rod, and a slot matching the rod is opened on the crossbar, and the rod is inserted into the slot.

[0013] By adopting the above technical solution, the inclined extrusion block is fixed on the crossbar by inserting the plug. When the diameter of the cable is different, the inclined extrusion block with different inclination angle can be selected, thereby controlling the distance between the two inclined plates and ensuring that the connector will not collide with the end of the inclined plate.

[0014] Preferably, the crossbar has a plurality of weight-reducing holes, and the weight-reducing holes are evenly distributed.

[0015] By adopting the above technical solution, the weight reduction hole can reduce the weight of the crossbar and prevent the crossbar from tilting under its own weight.

[0016] Preferably, the slider is provided with a vertical rod, a retaining ring is fixed on the vertical rod, and a mounting plate is fixed on the inclined plate. The mounting plate has a plurality of equally spaced mounting holes, and the vertical rod is inserted into the mounting holes at the corresponding positions. The vertical rod and the retaining ring provide support and positioning for the inclined plate.

[0017] By adopting the above technical solution, the vertical rod can position the inclined plate, and the retaining ring can support the inclined plate from the bottom, thus realizing the installation of the inclined plate. Moreover, when the vertical rod is inserted into different mounting holes, the distance between the two inclined plates can be changed, further adapting to cables of different diameters and expanding the applicability of the device.

[0018] Preferably, a positioning groove is provided on the inner side of the inclined plate, and a graphite sheet is pasted in the positioning groove.

[0019] By adopting the above technical solution, the graphite sheet can reduce the frictional force generated when the joint collides with the inclined plate, thus preventing the joint from being scratched.

[0020] Preferably, the sensing component includes an offset block, an offset groove is provided on the slider, the offset block is slidably disposed in the offset groove, and a vertical rod is fixed on the offset block. A second spring is provided between the offset block and the inner wall of the offset groove. The elastic coefficient of the second spring is less than that of the first spring. A top rod is fixed on the offset block. A limit switch is installed on the inner wall of the offset groove, and both the limit switch and the top rod are located inside the second spring.

[0021] By adopting the above technical solution, when the two inclined plates are squeezed to the sides by the joint and separated, the second spring will be compressed first. At this time, the offset block slides in the offset groove, the push rod squeezes the limit switch, and then the electric push rod drives the nozzle to move up.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the vision sensor malfunctions or the signal transmission fails, the cable connector passes through the tilting plate, which separates the two tilting plates to the sides. At this time, the sensing component is triggered, causing the electric push rod to lift upwards, which can still lift the printhead upwards, preventing the connector from colliding with the printhead and protecting the inkjet printer.

[0024] 2. When the cable connector enters the production line, the vision safety device first detects the connector. At this time, the electric push rod will rise, lifting the nozzle upwards on one hand, and separating the two sliders to the sides through the transmission component on the other hand, so that the connector will not rub or collide with the inclined plate.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses an adjustable cable connector anti-collision device.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 An adjustable cable connector anti-collision device includes a base plate 1 located directly below the cable. A support frame 5 and a support plate 6 are fixed to the base plate 1. A horizontal plate 8 is fixed above the support frame 5, and two symmetrically distributed sliders 9 are slidably mounted on the horizontal plate 8. Symmetrical inclined plates 10 are fixed to each of the two sliders 9, with the end of the inclined plates 10 with the larger opening distance pointing towards the cable entry direction. A positioning groove is formed on the inner side of the inclined plate 10, and a graphite sheet is adhered to the positioning groove. A vision sensor 7 is mounted on the support plate 6.

[0034] An electric actuator 2 is also fixed on the base plate 1. A connector 3 is connected to the fixed end of the electric actuator 2. A printhead 4 is connected to the upper side of the connector 3. The printhead 4 is used to connect to the inkjet printer to realize the inkjet printing function.

[0035] The slider 9 is equipped with a sensing component, which triggers the electric actuator 2 when the slider 9 moves outward. In addition, a transmission component is provided between the slider 9 and the electric actuator 2. When the electric actuator 2 moves upward, the two sliders 9 will separate from each other, and a first spring 24 is provided on the outside of the slider 9 to push the two sliders 9 closer together.

[0036] With the above setup, under normal circumstances, the vision sensor 7 will first detect the cable connector. Once the connector is detected, the electric actuator 2 will immediately rise. This rising action has a dual function: on the one hand, it lifts the nozzle 4 upward to prevent collision; on the other hand, the rising of the electric actuator 2 will cause the two sliders 9 to separate to the sides through the transmission assembly, thereby ensuring that the cable connector will not rub against or collide with the inclined plate 10 when it enters.

[0037] However, in abnormal situations, such as a problem with the vision sensor 7 or a signal transmission failure, the cable connector will still continue to enter the production line. In this case, the connector will pass over the tilting plates 10, and due to their size or position, will push the two tilting plates 10 apart. The graphite sheets attached to the positioning grooves inside the tilting plates 10 effectively reduce the friction generated when the connector comes into contact with the tilting plates 10, preventing the connector from being scratched.

[0038] When the tilting plate 10 is pushed open, the sensing component on the slider 9 is triggered, causing the electric actuator 2 to lift upwards again, thereby lifting the printhead 4. In this way, even if the vision sensor 7 malfunctions, the printhead 4 can be protected in time to avoid collision with the cable connector, thus protecting the inkjet printer.

[0039] Reference Figures 2-4 The transmission assembly includes a crossbar 11 fixed to the upper end of the electric actuator 2. Several weight-reducing holes 19 are evenly distributed on the crossbar 11. These holes 19 reduce the overall weight of the crossbar 11 while maintaining its structural strength. An inclined extrusion block 12 is also fixed to the crossbar 11. The inclined extrusion block 12 has inclined surfaces on both sides and is located directly below the crossbar 8.

[0040] Furthermore, the bottom of the inclined extrusion block 12 is fixed with a plug rod 17, and the crossbar 11 is provided with a slot 18 that matches the plug rod 17.

[0041] A first groove 13 is provided on the horizontal plate 8, and the slider 9 is slidably disposed in the first groove 13. A long slot 14 is provided at the bottom of the first groove 13, and the upper end of the inclined extrusion block 12 is inserted into the long slot 14.

[0042] A mounting groove 15 is provided at the bottom of the slider 9 near the inclined extrusion block 12, and a roller 16 is rotatably mounted in the mounting groove 15. When the electric push rod 2 moves upward, it will drive the crossbar 11 and the inclined extrusion block 12 to rise together. At this time, the inclined surface of the inclined extrusion block 12 will abut against the roller 16, and as the inclined extrusion block 12 continues to rise, the roller 16 and the slider 9 will be pushed to slide outward along the first slide groove 13 by the extrusion action of the inclined surface, thereby realizing the separation of the two sliders 9.

[0043] With the above configuration, when the electric actuator 2 is raised, it will drive the horizontal bar 11 fixed at its upper end to rise synchronously. Since the inclined extrusion block 12 is fixed to the horizontal bar 11 by the insertion rod 17, the rise of the horizontal bar 11 will drive the inclined extrusion block 12 to rise together. The inclined extrusion block 12 is located directly below the horizontal plate 8, and has inclined surfaces on both sides. During the rising process, the inclined surface extrudes the roller 16 set in the bottom mounting groove 15 on the side of the slider 9 closest to it, separating the two sliders 9 to both sides, and driving the two inclined plates 10 to separate from each other. This can prevent the inclined plates 10 from frequently rubbing against the cable connector.

[0044] The roller 16 plays a crucial role in the process of the inclined extrusion block 12 pressing the slider 9. It transforms the sliding friction between the inclined extrusion block 12 and the slider 9 into rolling friction, greatly reducing friction and friction loss. This not only extends the service life of the equipment but also reduces the noise generated during operation.

[0045] Furthermore, the device features flexible adjustment capabilities. When the cable diameter varies, the operator can select and replace the inclined extrusion blocks 12 with different tilt angles. The different tilt angles of the inclined extrusion blocks 12 result in varying degrees of pressure on the slider 9 during the ascent, thereby precisely controlling the distance between the two inclined plates 10. This ensures that cable connectors of different diameters will not collide with the ends of the inclined plates 10, improving the device's versatility and adaptability.

[0046] Meanwhile, several weight-reducing holes 19 are evenly distributed on the crossbar 11. These weight-reducing holes 19 effectively reduce the weight of the crossbar 11, prevent the crossbar 11 from tilting due to its own weight, and ensure the stability and reliability of the entire transmission assembly.

[0047] Reference Figure 2 and Figure 3 An installation plate 22 is fixed on the inclined plate 10, and the installation plate 22 has several equally spaced installation holes 23. A vertical rod 20 is provided on the slider 9, and a retaining ring 21 is fixed on the vertical rod 20. During assembly, the vertical rod 20 is inserted into the corresponding installation hole 23 on the installation plate 22.

[0048] The vertical rod 20 and the retaining ring 21 together provide reliable support and positioning for the tilting plate 10. The vertical rod 20 is inserted into the mounting hole 23 to ensure the horizontal stability of the tilting plate 10 and prevent it from shaking or shifting; while the retaining ring 21 limits the tilting plate 10 in the vertical direction to prevent it from falling off the vertical rod 20, thereby ensuring the firmness of the connection and the accuracy of the position between the tilting plate 10 and the slider 9.

[0049] With the above settings, by inserting the vertical rod 20 into the mounting holes 23 at different positions, the distance between the two inclined plates 10 can be flexibly changed, which can further adapt to cables of different diameters. When facing cables of different specifications, simply adjust the installation position of the vertical rod 20 to match the distance between the two inclined plates 10 with the cable diameter, thereby expanding the applicability of the device and improving its practicality and versatility.

[0050] Reference Figure 4 The sensing component includes an offset block 26, an offset groove 25 on the slider 9, the offset block 26 is slidably disposed in the offset groove 25, and the vertical rod 20 is fixed on the offset block 26. A second spring 27 is disposed between the offset block 26 and the inner wall of the offset groove 25. The elastic coefficient of the second spring 27 is less than that of the first spring 24. A push rod 29 is fixed on the offset block 26. A limit switch 28 is installed on the inner wall of the offset groove 25, and both the limit switch 28 and the push rod 29 are located inside the second spring 27.

[0051] With the above settings, when the two inclined plates 10 are squeezed to the sides by the joint and separated, the elastic coefficient of the second spring 27 is less than that of the first spring 24. The second spring 27 is compressed first. At this time, the offset block 26 slides in the offset groove 25, and the push rod 29 presses against the limit switch 28, which in turn causes the electric push rod 2 to drive the printhead 4 to move upward, thus achieving the effect of protecting the inkjet printer.

[0052] The implementation principle of this embodiment is as follows:

[0053] When the cable connector enters the production line, the vision sensor 7 first detects the connector. At this time, the electric push rod 2 will rise, lifting the printhead 4 upwards on one hand, and separating the two sliders 9 to the sides through the crossbar 11 and the inclined extrusion block 12 on the other hand, so that the connector will not rub or collide with the inclined plate 10. When the vision sensor malfunctions or the signal transmission has a problem, the cable connector passes through the inclined plate 10, separating the two inclined plates 10 to the sides. At this time, the offset block 26 slides in the offset groove 25, and the push rod 29 presses against the limit switch 28, causing the electric push rod 2 to rise upwards, which can still lift the printhead 4 upwards, preventing the connector from colliding with the printhead 4 and protecting the inkjet printer.

[0054] In summary, this device separates the two inclined plates 10 to the sides through the cable connector, triggering the sensing component, which causes the electric push rod 2 to lift upward, raising the printhead 4 upward, preventing the connector from colliding with the printhead 4, and thus protecting the inkjet printer.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
