Description

Technical Field

[0001] This invention relates to the field of automatic control technology, and in particular to a one-click operating system for scissors used in a light guide plate side-mounting device. Background Technology

[0002] During the production of light guide plates, side adhesives need to be attached to their edges to prevent light leakage from the sides. The specific operation for attaching the side adhesives is as follows: the side adhesive is adhered to the side of the light guide plate, and then cut to the desired length using scissors. To improve production efficiency, fully automated light guide plate side adhesive devices have replaced manual side adhesive application in the current production process. When using the fully automated device, the length of the side adhesive is cut using the scissors of the fully automated device.

[0003] However, current fully automatic light guide plate side-applying devices can only automate the side-applying operation. In actual production, when changing the side-applying tray, the discarded side-applying material at the beginning of the tray needs to be cut. Currently, this operation is performed as follows: the operator adjusts the beginning of the side-applying tray near the scissors, then walks to the control panel of the fully automatic light guide plate side-applying device and clicks the corresponding button (scissors up, scissors down, scissors clamp, scissors release). Then, the operator walks to the scissors and removes the cut side-applying material. This method requires the operator to run back and forth between the control panel and the scissors, making the operation extremely inconvenient. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a one-click operating system for scissors used in a light guide plate side-mounting device. The technical solution of the present invention is as follows: A one-button operating system for scissors used in a light guide plate side-mounting device includes a control switch SB installed near the scissors of the light guide plate side-mounting device, a magnetic switch X1 for controlling the lower limit of the movement of the scissor lifting cylinder, and a control component. X1 is installed below the scissor lifting cylinder. The control component includes an intermediate relay KA1 for controlling the scissor lifting cylinder, an intermediate relay KA2 for controlling the scissor extension cylinder, a time relay KT1 for controlling the scissor retraction time T1, a time relay KT2 for controlling the time T2 required for the scissors to rise from the moment they are released, an intermediate relay KA3 for sensing the signal output from the signal output terminal of X1 and controlling the energization or de-energization of KA2 and KT1, and an intermediate relay KA4 for controlling the action interlock. KA1 has coil terminals A1 and A2, normally open contacts NO1 and NO2, normally open contacts NO5 and NO6; KA2 has coil terminals A1 and A2, normally open contacts NO7 and NO8; KT1 has coil terminals A1 and A2, normally open contacts NO9 and NO10, normally closed contacts NC5 and NC6; KT2 has coil terminals A1 and A2, normally closed contacts NC11 and NC12; KA3 has coil terminals A1 and A2, normally open contacts NO3 and NO4; KA4 has normally closed contacts NC13 and NC14, normally closed contacts NC15 and NC16. The SB is connected between NC15 and A1 of KA1. NC15 is connected to A1 of NO2, NO5, NO8 and KT2. NC16 is connected to low level N and NO3. A1 of KA4 is connected to the automatic operation status signal line Y20 of the light guide plate side-attachment device. A2 of KA4 is connected to high level P and NC13. NC14 is connected to A1 of KA3. NC13 is connected to A1 of NC11 and KA2. A2 of KA3 is connected to the signal output terminal of X1. NO4 is connected to A2 of KT1 and NC6. A2 of KA1 is connected to A1 of KT1 and NC12. NO1 is connected to the action signal line Y64 of the scissor lifting cylinder. A2 of KA2 is connected to NC5. NO7 is connected to the action signal line Y65 of the scissor telescopic cylinder. NO9 is connected to NC11. NO10 is connected to A2 of KT2. When the light guide plate side-mounting device is in automatic operation, Y20 outputs a low level; when Y64 receives a low level, the scissor lifting cylinder descends, loses the low level, and the scissor lifting cylinder rises; when Y65 receives a low level, the scissor telescopic cylinder retracts, loses the low level, and the scissor telescopic cylinder opens; when the scissor lifting cylinder moves downward and senses X1, X1 closes, and the signal output terminal of X1 outputs a low level.

[0005] Optionally, when SB is a reset switch, A1 of KA1 and NO6 are connected by a wire.

[0006] Optionally, the voltage difference between the high level P and the low level N is 24V.

[0007] Optionally, the control component is installed in the power distribution box of the light guide plate side-mounting device.

[0008] Optionally, the control component is integrated on a PCB board, and the PCB board with the integrated control component can be detachably connected to the power distribution box.

[0009] All of the above-mentioned optional technical solutions can be combined arbitrarily, and the present invention will not provide a detailed description of the structure after each combination.

[0010] By means of the above solution, the beneficial effects of the present invention are as follows: By installing a control switch SB near the scissors of the light guide plate side-applying device and a magnetic switch X1 below the scissors lifting cylinder, and by setting up a control component, when the light guide plate side-applying device is in manual operation mode, the operator can operate the control switch SB near the scissors to realize the scissors' lowering, retracting, opening, and raising actions. This enables one-click execution of side-applying operations or the discard side-applying cutting operation at the beginning of the side-applying tray, eliminating the need for the operator to walk back and forth between the control panel and the scissors. This simplifies operation, improves efficiency, and reduces labor costs.

[0011] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0015] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0016] like Figure 1 As shown, the one-button operating system for the scissors of the light guide plate side-mounting device provided in this embodiment of the invention includes a control switch SB installed near the scissors of the light guide plate side-mounting device. Figure 3 The switch shown in the red box is a magnetic switch X1 used to control the lower limit of the movement of the scissor lifting cylinder and a control component. X1 is installed below the scissor lifting cylinder. The control component includes an intermediate relay KA1 for controlling the scissor lifting cylinder, an intermediate relay KA2 for controlling the scissor extension cylinder, a time relay KT1 for controlling the scissor retraction time T1, a time relay KT2 for controlling the time T2 required for the scissors to start rising from the moment they are released, an intermediate relay KA3 for sensing the signal output terminal of X1 and controlling KA2 and KT1 to be energized or de-energized, and an intermediate relay KA4 for controlling the action interlock. KA1 has coil terminals A1 and A2, normally open contacts NO1 and NO2, normally open contacts NO5 and NO6; KA2 has coil terminals A1 and A2, normally open contacts NO7 and NO8; KT1 has coil terminals A1 and A2, normally open contacts NO9 and NO10, normally closed contacts NC5 and NC6; KT2 has coil terminals A1 and A2, normally closed contacts NC11 and NC12; KA3 has coil terminals A1 and A2, normally open contacts NO3 and NO4; KA4 has normally closed contacts NC13 and NC14, normally closed contacts NC15 and NC16. The SB is connected between NC15 and A1 of KA1. NC15 is connected to A1 of NO2, NO5, NO8 and KT2. NC16 is connected to low level N and NO3. A1 of KA4 is connected to the automatic operation status signal line Y20 of the light guide plate side-attachment device. A2 of KA4 is connected to high level P and NC13. NC14 is connected to A1 of KA3. NC13 is connected to A1 of NC11 and KA2. A2 of KA3 is connected to the signal output terminal of X1. NO4 is connected to A2 of KT1 and NC6. A2 of KA1 is connected to A1 of KT1 and NC12. NO1 is connected to the action signal line Y64 of the scissor lifting cylinder. A2 of KA2 is connected to NC5. NO7 is connected to the action signal line Y65 of the scissor telescopic cylinder. NO9 is connected to NC11. NO10 is connected to A2 of KT2. When the light guide plate side-mounting device is in automatic operation, Y20 outputs a low level; when Y64 receives a low level, the scissor lifting cylinder descends, loses the low level, and the scissor lifting cylinder rises; when Y65 receives a low level, the scissor telescopic cylinder retracts, loses the low level, and the scissor telescopic cylinder opens; when the scissor lifting cylinder moves downward and senses X1, X1 closes, and the signal output terminal of X1 outputs a low level.

[0017] Specifically, this embodiment of the invention is applied to the manual operation state of the light guide plate side-mounting device. In the manual operation state, the Y20 output of the light guide plate side-mounting device is high. The working principle of this embodiment of the invention is as follows: When the light guide plate side-mounting device is in manual operation state, when the operator presses SB, the KA1 coil is energized, NO1 and NO2 of KA1 are turned on, Y64 receives a low level, and the scissors descend. When the scissors descend to the lower limit (i.e., X1 senses the scissor descent cylinder), X1 closes and is turned on, the signal output terminal of X1 outputs a low level, the KA3 coil is energized, NO3 and NO4 of KA3 are turned on, A2 of KA2 and KT1 receives a low level, at this time the KA2 and KT1 coils are energized, KT1 starts timing for 2 seconds (the timing time can be selected as needed) and NO7 and NO8 of KA2 are turned on, Y65 receives a low level, and the scissors retract. When KT1 times for 2 seconds, NC5 and NC6 of KT1 disconnect, NO9 and NO10 conduct, A2 of KA2 is de-energized, the KA2 coil is de-energized, Y65 loses its low level, the scissors open, A2 of KT2 is energized, the KT2 coil is energized and starts timing for 2 seconds. After 2 seconds, NC11 and NC12 disconnect, A2 of KA1 is de-energized, the KA1 coil is de-energized, NO1 and NO2 of KA1 disconnect, Y64 loses its low level, and the scissors rise. When the scissors rise, X1 disconnects, A2 of KA3 is de-energized, the KA3 coil is de-energized, NO3 and NO4 of KA3 disconnect, A2 of KT1 is de-energized, the KT1 coil is de-energized, NO9 and NO10 of KT1 disconnect, at this time A2 of KT2 is de-energized, and the KT2 coil is de-energized.

[0018] When the light guide plate side-attachment device is in automatic operation, Y20 receives a low level, the coil of KA4 is energized, NC13 and NC14 of KA4 are disconnected, and NC15 and NC16 are disconnected. NC14 and NC15 are not energized. Even if SB is pressed at this time, the one-button scissor operating system cannot be triggered. This setting ensures that the one-button scissor action system cannot be triggered when the light guide plate side-attachment device is in automatic operation, preventing operator error from cutting the side-attachment or causing an accident.

[0019] In addition, when the light guide plate side-mounting device is in manual operation, after the one-button scissor system completes its operation, all the coils of all components in the system except KA4 are de-energized.

[0020] It should be noted that the above-mentioned light guide plate side-applying device can be a light guide plate side-applying device on the market that can automatically perform the side-applying operation, but the waste side-applying operation of cutting the beginning of the side-applying material tray still requires manual assistance, such as the fully automatic light guide plate side-applying device disclosed in patent CN114706156B.

[0021] It should also be noted that the one-button scissor action system provided in this embodiment of the invention can not only perform the waste side-attachment cutting operation at the beginning of the side-attachment tray, but also cooperate with the operation panel of the light guide plate side-attachment device to perform side-attachment operation (the operator manually operates the side-attachment). Figure 2 The control panel shown has buttons for raising, lowering, clamping, and releasing the scissors for side-mounting operations.

[0022] In one specific embodiment, when SB is a reset switch, A1 and NO6 of KA1 are connected by a wire. In this case, when the operator presses SB, the coil of KA1 is energized and self-locks, and the operation is unaffected by the reset switch.

[0023] In one specific embodiment, the voltage difference between the high level P and the low level N is 24V to ensure the normal operation of each intermediate relay and time relay.

[0024] In one specific embodiment, the control component is installed in the power distribution box of the light guide plate side-mounting device, so as to save installation space and not affect the normal operation of the light guide plate side-mounting device.

[0025] In one specific embodiment, each of the above intermediate relays is a thin intermediate relay to save installation space for the control components; each time relay is a time relay with an accuracy of 0.1 seconds to improve the response accuracy of the control components.

[0026] In one specific embodiment, the control component is integrated onto a PCB board, and the PCB board with the integrated control component is detachably connected to the distribution box. This arrangement allows for easy maintenance of the control component by simply removing the PCB board from the distribution box and replacing it if any electrical components fail.

[0027] It should be noted that, Figure 1 In the connection relationships, if there is a dot at the intersection of straight lines, it means that the wires are connected; if the wires intersect but there is no dot, it means that the wires are not connected.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
