Description

Technical Field

[0001] The present application relates to the field of radiation processing technology, and in particular to an automatic induction radiation curing device. Background Art

[0002] Radiation curing, also known as UV / EB curing, refers to the technology of using ultraviolet light or electron beam as energy source to irradiate polymers or oligomers to make them undergo rapid chemical crosslinking and curing, which are called light curing and electron beam curing respectively. It mainly forms industrial product types such as radiation-cured coatings, radiation-cured inks, and radiation-cured adhesives. In addition, an industry has also been formed in the cross-linking and strengthening processing of plastics. Among them, radiation curing with ultraviolet light as the radiation energy source is also called ultraviolet light curing, or UV curing, and the products formed include UV-cured coatings, UV-cured inks, and UV-cured adhesives. Radiation curing with electron beam as the energy source is also called electron beam curing, or EB curing, and the products formed include EB-cured coatings, EB-cured inks, EB-cured adhesives, etc.

[0003] In the prior art, a common radiation curing device is installed in an irradiation room, which mainly includes a frame, a furnace body and a conveyor belt are installed on the frame, a feed port and a discharge port are provided on the furnace body, and the conveyor belt runs through the feed port. An irradiation host is installed inside the furnace body. During the radiation curing process of the material to be irradiated on the workpiece (paint, ink or adhesive, etc.), the conveyor belt transports the workpiece to the bottom of the irradiation host in sequence according to the set frequency and stays for a set time. The irradiation host irradiates the surface of the workpiece and then sends it out through the discharge port on the other side of the furnace body.

[0004] However, the existing radiation curing device cannot detect the curing effect of the material on the workpiece, and the operator is required to detect the curing effect of the material on the workpiece one by one. The detection efficiency and accuracy are low, and there is room for improvement. Utility Model Content

[0005] In order to improve the efficiency and accuracy of detecting workpieces that fail to meet curing standards, the present application provides an automatic induction radiation curing device.

[0006] The present application provides an automatic induction radiation curing device that adopts the following technical solution:

[0007] An automatic induction radiation curing device comprises a main conveyor belt, the main conveyor belt comprises a conveyor crawler, a plurality of baffles are fixedly connected to the conveyor crawler, a placement groove for placing a workpiece to be tested is formed between any two adjacent baffles, and a through hole is formed at the bottom of the placement groove; and:

[0008] A light source is fixedly mounted on the frame, mounted above the conveyor belt, and located on the discharge side of the irradiation host;

[0009] A light detector is fixedly mounted on the frame, located below the conveyor belt and opposite to the light source, and is used to detect the curing rate of the material on the workpiece and output a curing rate signal;

[0010] A signal processing module, connected to the signal output terminal of the light detector, for receiving and comparing the curing rate signal, and outputting a sorting control signal when the curing rate is less than a set value;

[0011] A sorting module is located on the side of the light source and the light detector away from the irradiation host, and is used to receive the sorting control signal and sort out the workpieces whose curing rate does not meet the standard and send them out;

[0012] The alarm module is used to detect the frequency of occurrence of workpieces with a curing rate that does not meet the standard, and output an alarm signal when the frequency of occurrence of workpieces with a curing rate that does not meet the standard is too high.

[0013] By adopting the above technical scheme, in the actual production and processing process, the workpiece can be placed through the placement groove on the surface of the conveyor crawler of the main conveyor belt, and the main conveyor belt conveys the workpieces one by one and stops under the irradiation host. When the workpiece is irradiated and passes between the light source and the light detector, the workpiece passes between the light source and the light detection device, and the light emitted by the light source passes through the material and the workpiece and is received by the light detection device. The light detector forms a spectrum and calculates the curing rate of the material and outputs a curing rate signal. The signal processing module compares the curing rate. If the curing effect of the material on the workpiece is good, the main conveyor belt transports the workpiece out of the irradiation room; if the curing effect of the material on the workpiece is poor, the sorting module sorts and sends out the unqualified workpiece, which can achieve the technical effect of automatically detecting the curing rate of the material on the workpiece and automatically sorting the material with poor curing effect. In addition, when the frequency of unqualified workpieces is too high, the alarm module can prompt the on-site operator to trace the upstream process or debug the irradiation host.

[0014] Preferably, the signal processing module includes a first single chip microcomputer.

[0015] By adopting the above technical solution, the first single chip microcomputer can realize automatic comparison of the curing rate, and when the curing rate is too low (the curing effect of the material is poor), it can automatically control the sorting module to sort out the workpieces that fail the curing.

[0016] Preferably, the sorting module comprises:

[0017] A secondary conveyor belt, located at a side of the light source away from the irradiation main machine, with a feed end connected to the main conveyor belt and a discharge end extending outside the irradiation room;

[0018] A telescopic cylinder, a cylinder body is fixedly connected to the frame, a driving end is fixedly connected with a push plate, a signal input end of the telescopic cylinder is signal-connected to a signal output end of the first single-chip microcomputer, and the telescopic cylinder receives the sorting control signal and drives the push plate to slide onto the auxiliary conveyor belt.

[0019] By adopting the above technical scheme, when the solidification rate of the material is unqualified, the first single-chip computer controls the telescopic cylinder to extend the cylinder shaft to drive the push plate to apply thrust to the workpiece, so that the workpiece is transferred from the main conveyor belt to the auxiliary conveyor belt and then sent out of the irradiation chamber by the auxiliary conveyor belt. Then the telescopic cylinder retracts the cylinder shaft, thereby achieving the technical effect of automatically sorting workpieces with unqualified material solidification rate.

[0020] Preferably, two baffles are fixedly connected to the frame, the two baffles are mounted above the auxiliary conveyor belt, and a limited position channel is formed between the two baffles.

[0021] By adopting the above technical solution, the two baffles can limit the movement trajectory of the workpiece, reducing the occurrence of the workpiece being pushed and dropped by the push plate.

[0022] Preferably, the two baffles each include a guide portion, and the two guide portions are arranged to be inclined inwardly along the direction in which the workpiece is sent out.

[0023] By adopting the above technical solution, the two guide parts are inclined inward along the direction of workpiece delivery, so that the limiting channel as a whole can be approximately Y-shaped, which can increase the opening width of the limiting channel and reduce the occurrence of the workpiece colliding with the baffle and falling.

[0024] Preferably, two guide rods are fixedly connected to the frame, and the push plate is provided with two sliding holes matched with the guide rods.

[0025] By adopting the above technical solution, the push plate slides along the axial direction of the guide rod, which can effectively reduce the push plate deviation and tilting during the sliding process driven by the telescopic cylinder, and effectively improve the stability of the push plate in performing the sorting action.

[0026] Preferably, the alarm module comprises:

[0027] An infrared emitting end is fixedly mounted on the frame and located on one side of the push plate, and is used to emit infrared rays;

[0028] An infrared receiving end is fixedly mounted on the frame and is located on a side of the push plate away from the infrared transmitting end, and is used to transmit a high-level signal when the push plate is blocked;

[0029] A second single chip microcomputer, whose signal input terminal is signal-connected to the signal output terminal of the infrared receiving terminal, is used to receive the high level signal and output an alarm signal when the high level signal occurs frequently;

[0030] The sound and light alarm is fixedly installed outside the irradiation room, and its signal input terminal is connected to the signal output terminal of the second single-chip computer, and is used for receiving the alarm signal and emitting a warning sound and flash.

[0031] By adopting the above technical solution, when the push plate slides between the infrared transmitting end and the infrared receiving end, the infrared receiving end is blocked by the push plate and cannot receive infrared rays and output a high-level signal. The second single-chip microcomputer can calculate the frequency of occurrence of unqualified workpieces cured within a set time length range by the high-level signal, and control the sound and light alarm to emit a warning sound and flash when the frequency of unqualified workpieces cured is too high.

[0032] In summary, the automatic induction radiation curing device of the present application includes at least one of the following beneficial technical effects:

[0033] 1. In the actual production and processing process, the workpiece can be placed through the placement groove on the surface of the conveyor crawler of the main conveyor belt. The main conveyor belt conveys the workpieces one by one and stops under the irradiation main machine. When the workpiece is irradiated and passes between the light source and the light detector, the workpiece passes between the light source and the light detection device. The light emitted by the light source passes through the material and the workpiece and is received by the light detection device. The light detector forms a spectrum and calculates the curing rate of the material and outputs a curing rate signal. The first single-chip computer compares the curing rate. If the curing effect of the material on the workpiece is good, the main conveyor belt transports the workpiece out of the irradiation room; if the curing effect of the material on the workpiece is poor, the sorting module sorts and sends out the unqualified workpiece, which can achieve the technical effect of automatically detecting the curing rate of the material on the workpiece and automatically sorting the material with poor curing effect;

[0034] 2. Through the coordination and use of the infrared transmitting end, the infrared receiving end, the second single-chip microcomputer and the sound and light alarm, when the push plate slides between the infrared transmitting end and the infrared receiving end, the infrared receiving end is blocked by the push plate and cannot receive infrared rays and output high-level signals. The second single-chip microcomputer can calculate the frequency of occurrence of unqualified workpieces cured within the set time length of the high-level signal, and control the sound and light alarm to emit warning sounds and flashes when the frequency of unqualified workpieces cured is too high, which can prompt on-site operators to trace the upstream process or debug the irradiation host, and can effectively avoid the continuous production of more defective products with a low pass rate, resulting in production waste.

[0039] The following is combined with Figure 1-3 This application is described in further detail.

[0040] Example

[0041] The present application embodiment discloses an automatic induction radiation curing device. Figure 1 , Figure 2 as well as Figure 3 , including a main conveyor belt 1, the main conveyor belt 1 includes a conveyor crawler 11, and a plurality of baffles 12 are fixedly connected to the conveyor crawler 11. A placement groove 13 for placing the workpiece to be measured is formed between any two adjacent baffles 12, and a through hole 14 is opened at the bottom of the placement groove 13.

[0042] And: a light source 2, fixedly mounted on a frame 3, mounted above the conveyor belt 11, and located on the discharge side of the irradiation host 7; a light detector 4, fixedly mounted on the frame 3, located below the conveyor belt 11, opposite to the light source 2, for detecting the curing rate of the material on the workpiece and outputting a curing rate signal; a signal processing module, connected to the signal output end of the light detector 4, for receiving and comparing the curing rate signal, and outputting a sorting control signal when the curing rate is less than a set value; a sorting module 5, located on the side of the light source 2 and the light detector 4 away from the irradiation host 7, for receiving the sorting control signal and sorting and sending out workpieces with unsatisfactory curing rates; an alarm module 6, for detecting the frequency of occurrence of workpieces with unsatisfactory curing rates, and outputting an alarm signal when the frequency of occurrence of workpieces with unsatisfactory curing rates is too high.

[0043] In the actual production and processing process, the workpiece can be placed through the placement groove 13 on the surface of the conveyor crawler 11 of the main conveyor belt 1. The main conveyor belt 1 transports the workpieces one by one and stops under the irradiation host 7. When the workpiece is irradiated and passes between the light source 2 and the light detector 4, the workpiece passes between the light source 2 and the light detector 4. The light emitted by the light source 2 passes through the material and the workpiece and is received by the light detector 4. The light detector 4 forms a spectrum and calculates the curing rate of the material and outputs a curing rate signal. The signal processing module compares the curing rate. If the curing effect of the material on the workpiece is good, the main conveyor belt 1 will transport the workpiece out of the irradiation room; if the curing effect of the material on the workpiece is poor, the sorting module 5 will sort and send out the unqualified workpiece, which can achieve the technical effect of automatically detecting the curing rate of the material on the workpiece and automatically sorting the material with poor curing effect. In addition, when the frequency of unqualified workpieces is too high, the alarm module 6 can be used to prompt the on-site operator to trace the upstream process or debug the irradiation host 7.

[0044] In the embodiment of the present application, the signal processing module adopts the first single chip microcomputer. The first single chip microcomputer can realize automatic comparison of curing rate, and when the curing rate is too low (the curing effect of the material is poor), it can automatically control the sorting module 5 to sort the workpieces with unqualified curing.

[0045] Reference Figure 1 and Figure 3 The sorting module 5 includes: an auxiliary conveyor belt 51, which is located on the side of the light source 2 away from the irradiation host 7, the feeding end is connected to the main conveyor belt 1, and the discharging end extends to the outside of the irradiation room; a telescopic cylinder 52, the cylinder body is fixedly connected to the frame 3, and the driving end is fixedly connected to a push plate 53. The signal input end of the telescopic cylinder 52 is connected to the signal output end of the first single-chip microcomputer. The telescopic cylinder 52 receives the sorting control signal and drives the push plate 53 to slide onto the auxiliary conveyor belt 51.

[0046] When the solidification rate of the material is unqualified, the first single-chip computer controls the telescopic cylinder 52 to extend the cylinder shaft to drive the push plate 53 to apply thrust to the workpiece, so that the workpiece is transferred from the main conveyor belt 1 to the auxiliary conveyor belt 51 and then sent out of the irradiation chamber by the auxiliary conveyor belt 51. Then the telescopic cylinder 52 retracts the cylinder shaft, thereby achieving the technical effect of automatically sorting workpieces with unqualified material solidification rate.

[0047] In the embodiment of the present application, two baffles 54 are fixedly connected to the frame 3, the two baffles 54 are mounted above the auxiliary conveyor belt 51, and a limited position channel 55 is formed between the two baffles 54. The two baffles 54 can limit the movement trajectory of the workpiece, reducing the occurrence of the workpiece being pushed and dropped by the push plate 53.

[0048] Reference Figure 1 The two baffles 54 both include a guide portion, and the two guide portions are arranged to be inclined inwardly along the direction in which the workpiece is sent out.

[0049] The two guide parts are inclined inwardly along the direction in which the workpiece is sent out, so that the limiting channel 55 can be arranged in a Y-shape as a whole, which can increase the opening width of the limiting channel 55 and reduce the occurrence of the workpiece colliding with the baffle 54 and falling.

[0050] Reference Figure 1 and Figure 2 Two guide rods 56 are fixedly connected to the frame 3 , and two sliding holes 531 matching with the guide rods 56 are formed on the push plate 53 .

[0051] The push plate 53 slides axially along the guide rod 56, which can effectively reduce the displacement and tilt of the push plate 53 when the telescopic cylinder 52 drives the push plate 53 to slide, and effectively improve the stability of the push plate 53 in performing the sorting action.

[0052] Reference Figure 1 , Figure 2 as well as Figure 3 The alarm module 6 includes: an infrared transmitting end 61, which is fixedly mounted on the frame 3 and located on one side of the push plate 53, and is used to transmit infrared rays; an infrared receiving end 62, which is fixedly mounted on the frame 3 and located on the side of the push plate 53 away from the infrared transmitting end 61, and is used to transmit a high-level signal when blocked by the push plate 53; a second single-chip microcomputer, whose signal input end is signal-connected to the signal output end of the infrared receiving end 62, and is used to receive the high-level signal and output an alarm signal when the high-level signal occurs frequently; an audible and visual alarm, which is fixedly mounted outside the irradiation room, whose signal input end is signal-connected to the signal output end of the second single-chip microcomputer, and is used to receive the alarm signal and emit a warning sound and flash.

[0053] When the push plate 53 slides between the infrared transmitting end 61 and the infrared receiving end 62, the infrared receiving end 62 is blocked by the push plate 53 and cannot receive infrared rays and output a high-level signal. The second single-chip microcomputer can calculate the frequency of occurrence of unqualified workpieces cured within a set time length range of the high-level signal, and control the sound and light alarm to emit a warning sound and flash when the frequency of unqualified workpieces cured is too high.

[0054] Please refer to Figure 2 In the embodiment of the present application, the frame 3 includes a mounting top plate 31, and two connecting plates 32 are fixedly connected to the bottom of the mounting top plate 31. The two connecting plates 32 are located on both sides of the two guide rods 56, and the infrared transmitting end 61 and the infrared receiving end 62 are respectively fixedly mounted on the opposite side walls of the two connecting plates 32.

[0055] The implementation principle of an automatic induction radiation curing device of the embodiment of the present application is as follows: in the actual production and processing process, the workpiece can be placed through the placement groove 13 on the surface of the conveyor crawler 11 of the main conveyor belt 1, and the main conveyor belt 1 conveys the workpieces one by one and stays under the irradiation host 7. When the workpiece is irradiated and passes between the light source 2 and the light detector 4, the workpiece passes between the light source 2 and the light detector 4, and the light emitted by the light source 2 passes through the material and the workpiece and is received by the light detector 4. The light detector 4 forms a spectrum and calculates the curing rate of the material and outputs a curing rate signal. The first single-chip microcomputer compares the curing rate. If the curing effect of the material on the workpiece is good, the main conveyor belt 1 transports the workpiece out of the irradiation room; if the curing effect of the material on the workpiece is poor, the sorting module 5 sorts and sends out the unqualified workpiece, which can achieve the technical effect of automatically detecting the curing rate of the material on the workpiece and automatically sorting the material with poor curing effect. In addition, when the frequency of unqualified workpieces is too high, the sound and light alarm can be used to prompt the on-site operator to trace the upstream process or debug the irradiation host 7.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
