Description

Technical Field

[0001] This utility model relates to the field of LED curing machine technology, specifically to an LED curing machine with automatic standby mode. Background Technology

[0002] An LED curing machine is a type of ultraviolet curing equipment. Its overall structure includes a frame, conveyor, cover, LED lamp assembly, fan, and electrical system. It uses LED light sources to emit high-intensity ultraviolet rays to achieve rapid curing of UV adhesives, films, or coatings. It is an important supporting equipment for coating and plating production lines.

[0003] When UV curing glass and other sheets, LED curing machines typically only have one detection switch at the feeding end to detect whether the sheet has been fed in. However, this single detection switch is easily triggered accidentally. Whether it is due to the operator's arm brushing against it or other reasons, it is identified as sheet feeding. As a result, the internal components of the LED curing machine, such as the conveyor, machine cover, LED light group, fan, and electrical system, all start working, leading to a waste of a lot of energy and an increase in production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic standby LED curing machine, which solves the problem that existing LED curing machines with only a detection switch at the feeding end are prone to accidental activation, resulting in a waste of a lot of energy and an increase in production costs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An automatic standby LED curing machine includes a curing machine and a horizontal roller conveyor at the feed end. The horizontal roller conveyor is equipped with two support frames parallel to the rollers. A slide rail perpendicular to the rollers is slidably connected horizontally below the support frames. Two sliders are slidably connected below the slide rails. Detection switch A and detection switch B are respectively installed at the bottom of the two sliders. Detection switch B is located at the bottom of the slider near the curing machine. Detection switch C is also installed above the output end of the curing machine.

[0007] The detection switches A, B, and C are all connected to the PLC signal of the curing machine. The PLC is also connected to the timing module, the electrical drive module of the curing machine, and the roller drive module.

[0008] Preferably, the support frame is disposed on the horizontal roller conveyor at one end away from the curing machine.

[0009] Preferably, at least two parallel slide rails are provided below the support frame.

[0010] Preferably, a light rod is fixed below the support frame, the slide rail is slidably sleeved on the surface of the light rod, a ball-head spring plunger is installed at the top of the slide rail corresponding to the position of the support frame, and a positioning groove is provided at equal intervals on the top of the inner wall of the support frame.

[0011] Preferably, the slide rail is provided with slide grooves on both sides, the slider is slidably connected to the slide rail by engaging with the slide grooves, a ball-head spring plunger is installed on the top of the slider, and positioning grooves are provided at equal intervals on the bottom of the slide rail.

[0012] Preferably, the detection switch A, detection switch B and detection switch C are all diffuse reflection type photoelectric switches.

[0013] Preferably, the electrical drive module includes a power supply for the conveyor, LED lights, and fan inside the curing machine.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention ensures that the curing machine only continues to operate when detection switches A and B sequentially detect the input of sheet material, effectively avoiding the problem of accidental activation associated with a single detection switch. Otherwise, if detection switch C detects the sheet material leaving and neither detection switches A nor B detects any sheet material input for a certain period, the PLC-controlled electrical drive module will pause the operation of the conveyor, LED lights, and fan within the curing machine, achieving a standby state. This allows the curing machine to accurately detect incoming materials and selectively maintain either a working or standby state based on the sheet material input. By using standby mode, unnecessary energy consumption is reduced, solving the problem of existing LED curing machines that only have one detection switch at the feeding end, which is prone to accidental activation, leading to significant energy waste and increased production costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: an automatic standby LED curing machine, including a curing machine 1 and a horizontal roller conveyor 2 set at the feeding end. Two support frames 3 parallel to the roller are set on the horizontal roller conveyor 2. The support frames 3 are set on one end of the horizontal roller conveyor 2 away from the curing machine 1. A slide rail 4 perpendicular to the roller is horizontally slidably connected below the support frame 3.

[0024] At least two parallel slide rails 4 are provided below the support frame 3. Two sets of detection switches A6 and B7 are used as references to avoid accidental activation. A light rod 13 is fixed below the support frame 3. The slide rail 4 is slidably sleeved on the surface of the light rod 13. A ball head spring plunger 14 is installed at the top of the slide rail 4 corresponding to the position of the support frame 3. Positioning grooves 301 are provided at equal intervals on the top of the inner wall of the support frame 3.

[0025] Two sliders 5 are slidably connected below the slide rail 4. Slide grooves 401 are provided on both sides of the slide rail 4. The sliders 5 are slidably connected to the slide rail 4 by engaging with the slide grooves 401. A ball head spring plunger 12 is installed on the top of the slider 5. Positioning grooves 402 are provided at equal intervals on the bottom of the slide rail 4. Detection switch A6 and detection switch B7 are respectively installed on the bottom of the two sliders 5. Detection switch B7 is located on the bottom of the slider 5 near the curing machine 1. Detection switch C8 is also installed above the output end of the curing machine 1.

[0026] Detection switches A6, B7, and C8 are all diffuse reflection type photoelectric switches. Detection switches A6, B7, and C8 are all connected to the PLC9 signal of curing machine 1. PLC9 is also connected to the timing module 10 and the electrical drive module 11 of curing machine 1. The timing module 10 is a delay timer, and the electrical drive module 11 includes the drive power supply for the conveyor, LED light group, and fan inside curing machine 1.

[0027] Working principle:

[0028] Move the slider 5 along the slide rail 4, adjust the distance between detection switches A6 and B7 to ensure it is greater than the length of the current curing board. Position the slider 5 using the ball-head spring plunger 12 and positioning groove 402 to prevent deviation. A board input signal is only generated when detection switches A6 and B7 detect board input sequentially; otherwise, it is a false signal. PLC9 drives the curing machine 1 to operate via the electrical drive module. When detection switch C8 detects board removal, and detection switches A6 and B7 do not detect board input for a certain period (this time threshold is preset via the PLC9 panel of curing machine 1), PLC9 controls the electrical drive module to pause the conveyor, LED lights, and fan inside curing machine 1, achieving standby mode. Curing machine 1 selectively maintains working and standby modes based on board input, reducing unnecessary energy consumption and costs through standby.

[0029] The specific implementation steps are as follows:

[0030] S1. Hardware Connection:

[0031] Connect the three detection switches to the three digital input points of the PLC (e.g., X0, X1, X2).

[0032] Prepare a digital output point (e.g., Y0) of the PLC to control the standby command of the curing machine;

[0033] Ensure all devices are properly powered.

[0034] S2, Control Logic Programming:

[0035] X0: Input detection switch A

[0036] X1: Input detection switch B

[0037] X2: Output detection switch C

[0038] Y0: Standby command output

[0039] M0: Internal relay (board entry confirmation)

[0040] T1: Delay Timer

[0041] When detection switch A is triggered (X0 ON) and detection switch B is not triggered (X1 OFF), internal relay M0 is activated, indicating that a board is between A and B and is entering. The activation of M0 signifies that the system has confirmed that a board is flowing in and has begun to track it.

[0042] When the output detection switch C (X2) is triggered (indicating that the board is leaving) and the system is in the board entry confirmation state (M0 ON), the delay timer T1 is started, which means that a board tracked by the system has left the curing area. At this time, the time without new board input is calculated.

[0043] When timer T1 reaches its countdown (indicating that 30 seconds have passed since the area was cleared) and no new material is triggered to activate detection switch A (X0 OFF), the standby command output Y0 is activated. The system will only enter standby mode if both conditions are met: "the curing area is cleared" and "no new material is added for a period of time".

[0044] At any time, whenever a new board material triggers the detection switch A (rising edge of X0), M0 and timer T1 are immediately reset.

[0045] Cancel the previous "clear" state; if the system is in standby mode, it will immediately exit standby mode.

[0046] In standby mode (Y0 ON), as soon as the detection switch A detects a new board (rising edge of X0), the standby command Y0 is immediately reset (closed), ensuring that the curing machine can start instantly when the production line resumes, with an extremely fast response speed.

[0047] By sequentially triggering detection switches A and B, it is confirmed that the board material is flowing in the forward direction, preventing false triggers and misjudgments. By output detection switch C, it is known exactly when the last board material leaves the curing area. Combined with the "clear" event and "delay" judgment, it is ensured that the system only enters standby mode when the production line actually stops. As soon as a new board material arrives, the system is immediately awakened to ensure production continuity.

[0048] This logic was handled by professional automation engineers who wrote the program, wired it, and debugged it, and then fine-tuned the delay time in actual production to achieve the best results.

[0049] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
