Description

Technical Field

[0001] The present invention relates to the technical field of color sorters, and in particular to a color sorting lamp bracket and a temperature control method for the color sorting lamp bracket. Background Art

[0002] A color sorter is a machine that integrates optics, mechanics, electricity, computing, and pneumatics. Traditional color sorters generally distinguish different materials based on color differences. For materials of different materials, infrared light can be used as the light source to distinguish different materials based on the differences in infrared signals of materials of different materials. For some materials, due to the differences in fluorescence stimulated by ultraviolet light, ultraviolet lamps can be used as the light source to sort the materials.

[0003] The light source of the color sorter generally needs to be equipped with a heat dissipation system during the lighting process. When the common heat dissipation device dissipates heat for the profile on which the light source is installed, the heat dissipation effect on the profile is usually uneven, resulting in temperature differences on the profile, which in turn causes the profile to deform. This affects the uniformity of lighting, and the air temperature around the circuit boards, lenses and other components near the two ends of the profile and the circuit boards, lenses and other components in the middle area of ​​the profile is quite different, which can easily cause inconsistent sorting effects at different channels of the sorting machine, and also affect the sorting effect. Summary of the invention

[0004] The purpose of the present invention includes providing a color sorting lamp bracket, which can improve the deformation problem caused by uneven heat dissipation in the prior art.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0054] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0055] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0056] In an embodiment of the present application, a color sorter (not shown) is provided, which is configured to distinguish multiple types of articles according to the color differences of the multiple articles, and to group the differentiating multiple articles. The color sorter includes multiple color sorting lamps, which emit preset light sources. When the light sources are projected onto the articles, the types of the articles can be distinguished according to the differences in light emitted by the articles in response to the light emitted by the light sources. The color sorting lamps can be white light LED lamps, halogen lamps or ultraviolet lamps.

[0057] In addition, in order to facilitate the normal operation of the color sorting lamp, a structure for carrying the color sorting lamp is provided in the color sorting machine to provide a bearing function for the color sorting lamp and ensure that the color sorting lamp can operate stably. Of course, during the operation of the color sorting lamp, the color sorting lamp emits a lot of heat. Therefore, the color sorting machine is also provided with a heat dissipation structure to provide heat dissipation for the structure for carrying the color sorting lamp.

[0058] In the prior art, since the conventional heat dissipation device provides uneven heat dissipation to the structure carrying the color sorting lamp, the structure carrying the color sorting lamp is deformed, thereby affecting the direction of the light projected by the color sorting lamp, making the illumination light on the object uneven, which affects the effect of the color sorter on sorting the objects.

[0059] In order to improve the above technical problems, a color sorter in this application is provided. Figure 1 The color sorting machine of the present application includes a color sorting lamp bracket 10, which is configured to install a color sorting lamp to provide a bearing function for the color sorting lamp. The color sorting lamp bracket 10 can improve the deformation problem caused by uneven heat dissipation in the prior art.

[0060] Please refer to Figure 1 and Figure 2The color sorting lamp bracket 10 includes a carrier 100, a fan 300, a first temperature control device 410, a second temperature control device 420, a controller 500 and a plurality of reflective modules 200. The plurality of reflective modules 200 are arranged on the carrier 100 at intervals along the extension direction of the carrier 100, and the reflective modules 200 are configured to install color sorting lamps; in other words, the plurality of color sorting lamps can be respectively installed on the plurality of reflective modules 200, and when the color sorting lamps emit light, the reflective modules 200 can reflect the light to a designated area to facilitate sorting of items. The first temperature control device 410 and the second temperature control device 420 are respectively installed at both ends of the carrier 100, and the first temperature control device 410 and the second temperature control device 420 are both configured to detect the temperature of the carrier 100; the first temperature control device 410 is configured to detect the temperature of one end of the carrier 100, and the second temperature control device 420 is configured to detect the temperature of the other end of the carrier 100. The fan 300 is disposed at one end of the carrier 100, and the fan 300 is configured to guide the airflow to flow along the carrier 100. The first temperature control device 410 and the second temperature control device 420 are both electrically connected to the controller 500; the controller 500 is electrically connected to the fan 300, and the controller 500 is configured to control the fan 300 to rotate forward or reverse according to the first temperature value detected by the first temperature control device 410 and the second temperature value detected by the second temperature control device 420.

[0061] Optionally, in some embodiments of the present application, the fan 300 and the first temperature control device 410 are installed at the same end of the carrier 100. In addition, it should be noted that the first temperature control device 410 and the second temperature control device 420 can be temperature sensors.

[0062] As described above, when the color sorting lamp bracket 10 is applied to a color sorting machine, the color sorting lamp is installed on the reflective module 200. In addition, when the color sorting lamp is turned on, the color sorting lamp generates heat. The airflow can flow along the carrier 100 by operating the fan 300, thereby providing heat dissipation to the carrier 100. In addition, the temperature at both ends of the carrier 100 can be detected by the first temperature control device 410 and the second temperature control device 420, and the first temperature value and the second temperature value detected can be sent to the controller 500. The controller 500 controls the fan 300 to rotate forward or reverse according to the temperature at both ends of the carrier 100, so that the direction of the airflow can be repeatedly switched to guide the airflow to flow along the carrier 100 from both ends of the carrier 100, so that the heat dissipation effect at both ends of the carrier 100 is roughly the same, thereby achieving the purpose of uniform heat dissipation of the carrier 100, and improving the deformation problem caused by uneven heat dissipation in the prior art.

[0063] It should be noted that, when the airflow flows from one end of the carrier 100 where the first temperature control device 410 is provided to one end of the carrier 100 where the second temperature control device 420 is provided, the airflow is heated at the end of the carrier 100 where the first temperature control device 410 is provided, so that when the airflow flows to the end of the carrier 100 where the second temperature control device 420 is provided, the heat dissipation effect of the airflow is reduced. Similarly, when the airflow flows from one end of the carrier 100 where the second temperature control device 420 is provided to one end of the carrier 100 where the first temperature control device 410 is provided, the airflow is heated at the end of the carrier 100 where the second temperature control device 420 is provided, so that when the airflow flows to the end of the carrier 100 where the first temperature control device 410 is provided, the heat dissipation effect of the airflow is reduced. In other words, when the airflow flows in the same direction all the time, due to the different heat dissipation effects of the airflow on the two ends of the carrier 100, the temperature of one end of the carrier 100 is higher than the temperature of the other end, thereby causing the above technical problems. Therefore, in the color sorting lamp bracket 10 provided in the present application, the controller 500 controls the fan 300 to rotate forward or reverse according to the temperature at both ends of the carrier frame 100, so that the airflow repeatedly changes the flow direction, thereby making the airflow have a similar heat dissipation effect on both ends of the carrier frame 100, so that the temperature difference at both ends of the carrier frame 100 can be reduced, and the deformation problem caused by uneven heat dissipation in the prior art can be improved.

[0064] Optionally, in some embodiments of the present application, the support frame 100 includes a support body 110 and a mounting portion 120. The support body 110 is in an elongated strip shape. The mounting portion 120 is arranged on the outside of the support body 110, and the mounting portion 120 extends along the support body 110; a plurality of reflective modules 200 are arranged on the mounting portion 120 at intervals. The first temperature control device 410 and the second temperature control device 420 are both arranged on the outside of the support body 110 and located at both ends of the support body 110. The fan 300 is arranged at one end of the support body 110 and is configured to guide the airflow to flow along the support body 110. Among them, the mounting portion 120 provides a bearing function for the reflective module 200, and the mounting portion 120 is also configured to transfer the heat of the luminous film group to the support body 110. When the fan 300 is in operation, the airflow flows along the support body 110, thereby providing a heat dissipation function to the support body 110, so that the heat dissipation of the support frame 100 as a whole can be achieved.

[0065] In order to improve the heat dissipation efficiency, in some embodiments of the present application, a wind channel 111 is provided inside the bracket body 110, and the wind channel 111 penetrates the bracket body 110 along the extension direction of the bracket body 110; the fan 300 is installed at one end of the wind channel 111 and is configured to guide the airflow to flow along the wind channel 111. Optionally, the wind channel 111 is a channel provided inside the bracket body 110. In other words, when the fan 300 is in operation, the airflow flows inside the bracket body 110 to provide heat dissipation for the bracket body 110. The wind channel 111 has two openings, which are respectively located at the two ends of the bracket body 110, and the fan 300 is installed at one end of the bracket body 110 where the first temperature control device 410 is provided.

[0066] It should be understood that in other embodiments of the present application, other methods may be used to replace the setting of the wind channel 111. For example, a ventilation slot is provided on the bracket body 110, and the ventilation slot penetrates the bracket body 110 along the extension direction of the bracket body 110, and the ventilation slot has an opening on the side of the bracket body 110 away from the mounting portion 120, and the fan 300 can guide the airflow to flow along the ventilation slot. For another example, a plurality of heat sinks are arranged at intervals on the side of the bracket body 110 away from the mounting portion 120, and the plurality of heat sinks are all extended along the extension direction of the bracket body 110. In this case, a plurality of channels are formed between the plurality of heat sinks, and the fan 300 can guide the airflow to flow in the plurality of channels.

[0067] In addition, in order to improve the heat dissipation efficiency of the wind channel 111, a heat sink 112 is further provided inside the wind channel 111, and both sides of the heat sink 112 are connected to the inner peripheral wall of the wind channel 111. After the bracket body 110 receives the heat transferred by the mounting portion 120, the heat sink 112 is dissipated inside the wind channel 111, so that the airflow can take away the heat to improve the heat dissipation efficiency. Optionally, the heat sink 112 is in the form of a sheet, and the heat sink 112 can be provided in plurality, and the plurality of heat sinks 112 are cross-disposed inside the wind channel 111 to improve the heat dissipation efficiency of the wind channel 111.

[0068] Furthermore, in some embodiments of the present application, a plurality of convex bumps 113 are further provided on the inner peripheral wall of the heat sink 112 and the wind channel 111 to increase the contact area between the inner peripheral wall of the wind channel 111 and the airflow, thereby improving the heat dissipation efficiency. The convex bumps 113 may be a plurality of hemispherical protrusion structures; of course, the convex bumps 113 may also be a strip structure, and the strip structure may extend along the bracket body 110.

[0069] It should be understood that in other embodiments of the present application, the heat sink 112 or the convex hump 113 may be eliminated.

[0070] Optionally, the mounting portion 120 includes a first mounting platform 121 and a second mounting platform 122; the first mounting platform 121 and the second mounting platform 122 both extend along the bracket body 110, and the first mounting platform 121 and the second mounting platform 122 are arranged on the bracket body 110 at intervals. The reflective module 200 is mounted on the first mounting platform 121 and the second mounting platform 122; the first temperature control device 410 and the second temperature control device 420 are both located between the first mounting platform 121 and the second mounting platform 122. By arranging the first temperature control device 410 and the second temperature control device 420 between the first mounting platform 121 and the second mounting platform 122, the sensitivity of the first temperature control device 410 and the second temperature control device 420 in detecting the temperature of the bracket body 110 can be improved, and the detection accuracy can be improved at the same time. Of course, the first mounting platform 121 and the second mounting platform 122 can also provide protection for the first temperature control device 410 and the second temperature control device 420 to prevent the first temperature control device 410 and the second temperature control device 420 from being damaged by external collision.

[0071] Of course, in other embodiments of the present application, the first temperature control device 410 and the second temperature control device 420 may also be installed at other locations, for example, a side of the bracket body 110 away from the installation portion 120 .

[0072] In addition, in some other embodiments of the present application, a first mounting platform 121 is provided with a first mounting groove 1211, and the first mounting groove 1211 is provided along the first mounting platform 121; a second mounting groove 1221 is provided on the second mounting platform 122, and the second mounting groove 1221 is provided along the second mounting platform 122. The reflective module 200 can be installed on the first mounting platform 121 and the second mounting platform 122 by means of fixing members such as screws, and one end of the fixing member can extend into the first mounting groove 1211 and the second mounting groove 1221, thereby improving the installation stability of the reflective module 200. In addition, by setting the first mounting groove 1211 and the second mounting groove 1221, the contact area between the first mounting platform 121 and the second mounting platform 122 and the reflective module 200 can be reduced. In other words, the contact area between the reflective module 200 and the air is increased, so that the heat directly dissipated into the air by the reflective module 200 can be increased, thereby improving the heat dissipation efficiency of the reflective module 200; at the same time, it can also ensure that the first mounting platform 121 and the second mounting platform 122 effectively transfer heat to the bracket body 110.

[0073] Of course, in some other embodiments of the present application, the first installation groove 1211 and the second installation groove 1221 may also be eliminated.

[0074] Optionally, see Figure 3 and Figure 4In order to facilitate the installation of the reflective module 200 and the first mounting platform 121 and the second mounting platform 122, in some embodiments of the present application, the end of the reflective module 200 is provided with a first support ear 210 and a second support ear 220, and the first support ear 210 and the second support ear 220 are arranged at intervals at the end of the reflective module 200; the first support ear 210 is connected to the first mounting platform 121, and the second support ear 220 is connected to the second mounting platform 122. It should be noted that the first support ear 210 and the second support ear 220 are provided on both opposite sides of the reflective module 200, so that the installation stability of the reflective module 200 is improved through the cooperation between the two sides of the reflective module 200 and the first mounting platform 121 and the second mounting platform 122.

[0075] In addition, in order to prevent the heat generated by the reflective module 200 from affecting the first temperature control device 410 and the second temperature control device 420 to detect the temperature of the bracket body 110. Optionally, the distance between the first temperature control device 410 and the adjacent reflective module 200 is greater than or equal to the distance between two adjacent reflective modules 200. And / or, the distance between the second temperature control device 420 and the adjacent reflective module 200 is greater than or equal to the distance between two adjacent reflective modules 200. Among them, and / or indicate that, in some other embodiments of the present application, only the distance between the first temperature control device 410 and the adjacent reflective module 200 may be greater than or equal to the distance between two adjacent reflective modules 200, or only the distance between the second temperature control device 420 and the adjacent reflective module 200 may be greater than or equal to the distance between two adjacent reflective modules 200, or, as in the embodiments of the present application, the distance between the first temperature control device 410 and the adjacent reflective module 200 is greater than or equal to the distance between two adjacent reflective modules 200, and the distance between the second temperature control device 420 and the adjacent reflective module 200 is greater than or equal to the distance between two adjacent reflective modules 200.

[0076] At the same time, since the first temperature control device 410 and the second temperature control device 420 are far away from the reflective module 200, it can be prevented from affecting the first temperature control device 410 or the second temperature control device 420 when the color selection lamp is installed.

[0077] In the embodiment of the present application, a reflective groove 230 is provided on the reflective module 200, and the reflective groove 230 is configured to install a color sorting lamp, so that the reflective module 200 can provide a certain protection for the color sorting lamp. In addition, the inner peripheral wall of the reflective groove 230 is arc-shaped, so that the reflective module 200 can reflect the light emitted by the color sorting lamp to a specified position, thereby improving the sorting accuracy.

[0078] Based on the color sorting lamp bracket 10 and color sorting machine provided above, the embodiment of the present application also provides a temperature control method of the color sorting lamp bracket 10 to improve the deformation problem caused by uneven heat dissipation in the prior art. It should be noted that in the embodiment of the present application, the temperature control method of the color sorting lamp bracket 10 is executed by the controller 500. Figure 5 and Figure 6 The temperature control method of the color sorting lamp bracket 10 includes:

[0079] Step S10: receiving a first temperature value and a second temperature value.

[0080] The first temperature value is obtained by the first temperature control device 410 detecting the temperature of the end of the carrier 100, and the first temperature control device 410 sends the first temperature value to the controller 500, and the controller 500 receives the first temperature value. The second temperature value is obtained by the second temperature control device 420 detecting the temperature of the end of the carrier 100, and the second temperature control device 420 sends the second temperature value to the controller 500, and the controller 500 receives the second temperature value.

[0081] Step S20 , controlling the fan 300 to rotate forward or reverse according to the first temperature value, the second temperature value and the operation mode of the fan 300 .

[0082] In an embodiment of the present application, when the fan 300 rotates forward, the airflow is guided to flow from one end of the carrier frame 100 where the first temperature control device 410 is set to one end of the carrier frame 100 where the second temperature control device 420 is set; when the fan 300 rotates reversely, the airflow is guided to flow from one end of the carrier frame 100 where the second temperature control device 420 is set to one end of the carrier frame 100 where the first temperature control device 410 is set.

[0083] Optionally, see Figure 7 , step S20 may include:

[0084] Step S211 : when the fan 300 rotates forward, a difference between the second temperature value and the first temperature value is calculated to obtain a first temperature difference.

[0085] It should be noted that, when the fan 300 rotates forward, the airflow flows from one end of the carrier 100 where the first temperature control device 410 is provided to one end of the carrier 100 where the second temperature control device 420 is provided. In other words, the airflow enters the wind channel 111 from one end of the carrier 100 where the first temperature control device 410 is provided. At this time, the airflow provides a better heat dissipation effect to the end of the carrier 100 where the first temperature control device 410 is provided. Therefore, after the fan 300 rotates forward for a period of time, the temperature of one end of the carrier 100 where the second temperature control device 420 is provided is higher than the temperature of one end of the carrier 100 where the first temperature control device 410 is provided. Therefore, the temperature difference between the two ends of the carrier 100 is determined by subtracting the first temperature value from the second temperature value.

[0086] Step S212: determine whether the first temperature difference is greater than or equal to a first preset temperature value.

[0087] Step S213: If the first temperature difference is greater than or equal to the first preset temperature value, control the fan 300 to rotate in reverse.

[0088] In other words, if the result of the determination in step S212 is yes, the controller 500 controls the fan 300 to rotate in reverse.

[0089] It should be noted that, when the first temperature difference is greater than the first preset temperature value, it means that the temperature difference between the two ends of the carrier 100 is greater than or equal to the first preset temperature value, that is, the temperature difference between the two ends of the carrier 100 is large, which may cause deformation of the carrier 100. Therefore, in this case, the fan 300 is controlled to reverse so that the airflow flows from the end of the carrier 100 where the second temperature control device 420 is set to the end of the carrier 100 where the first temperature control device 410 is set, so as to improve the heat dissipation effect of the end of the carrier 100 where the second temperature control device 420 is set, thereby reducing the temperature difference between the two ends of the carrier 100, and preventing the deformation of the carrier 100 caused by the excessive temperature difference between the two ends of the carrier 100.

[0090] Step S214: If the first temperature difference is less than the first preset temperature value, the fan 300 is controlled to maintain forward rotation.

[0091] In other words, when the determination result in step S212 is negative, the controller 500 controls the fan 300 to maintain the forward rotation.

[0092] If the first temperature difference is less than the first preset temperature value, it means that the temperature difference between the two ends of the support frame 100 is still within the allowable range, so the fan 300 can be maintained to run in the forward direction.

[0093] Also, see Figure 8 , step S20 further includes:

[0094] Step S221: When the fan 300 rotates in reverse, a difference between the first temperature value and the second temperature value is calculated to obtain a second temperature difference.

[0095] It should be noted that, when the fan 300 is reversed, the airflow flows from one end of the carrier 100 where the second temperature control device 420 is provided to one end of the carrier 100 where the first temperature control device 410 is provided. In other words, the airflow enters the wind channel 111 from one end of the carrier 100 where the second temperature control device 420 is provided. At this time, the airflow provides a better heat dissipation effect to the end of the carrier 100 where the second temperature control device 420 is provided. Therefore, after the fan 300 is reversed for a period of time, the temperature of one end of the carrier 100 where the first temperature control device 410 is provided is higher than the temperature of one end of the carrier 100 where the second temperature control device 420 is provided. Therefore, the temperature difference between the two ends of the carrier 100 is determined by subtracting the second temperature value from the first temperature value.

[0096] Step S222: determine whether the second temperature difference is greater than or equal to the second preset temperature value.

[0097] It should be noted that, in some embodiments of the present application, the second preset temperature value may be equal to the first preset temperature value. Of course, in other embodiments of the present application, the second preset temperature value may not be equal to the first preset temperature value. For example, in the color sorter, the parts arranged at the two ends of the carrier 100 are different, which may affect the heat dissipation effect provided by the fan 300. For example, other heating elements are arranged near the end of the carrier 100 where the first temperature control device 410 is arranged. In order to prevent the temperature rise rate of the end of the carrier 100 where the first temperature control device 410 is arranged too fast and cause the carrier 100 to deform, it is necessary to control the fan 300 to switch the rotation direction when the temperature of the end of the carrier 100 where the first temperature control device 410 is arranged is slightly higher than the temperature of the end of the carrier 100 where the second temperature control device 420 is arranged. In this case, the second preset temperature value is less than the first preset temperature value.

[0098] Step S223: If the second temperature difference is greater than or equal to the second preset temperature value, control the fan 300 to rotate forward.

[0099] In other words, when the determination result in step S222 is YES, the controller 500 controls the fan 300 to rotate forward.

[0100] It should be noted that, when the second temperature difference is greater than the second preset temperature value, it means that the temperature difference between the two ends of the carrier 100 is greater than or equal to the second preset temperature value, that is, the temperature difference between the two ends of the carrier 100 is large, which may cause deformation of the carrier 100. Therefore, in this case, the fan 300 is controlled to rotate forward so that the airflow flows from the end of the carrier 100 where the first temperature control device 410 is set to the end of the carrier 100 where the second temperature control device 420 is set, so as to improve the heat dissipation effect of the end of the carrier 100 where the first temperature control device 410 is set, thereby reducing the temperature difference between the two ends of the carrier 100, and preventing the deformation of the carrier 100 caused by the excessive temperature difference between the two ends of the carrier 100.

[0101] Step S224: If the second temperature difference is less than the second preset temperature value, the fan 300 is controlled to maintain reverse rotation.

[0102] In other words, when the determination result in step S222 is negative, it indicates that the temperature difference between the two ends of the carrier 100 is still within the allowable range, and the controller 500 controls the fan 300 to maintain reverse rotation.

[0103] In summary, the color sorting lamp bracket 10, the color sorting machine, and the temperature control method of the color sorting lamp bracket 10 applied to the color sorting lamp bracket 10 and the color sorting machine provided in the embodiment of the present application can make the airflow flow along the carrier 100 by the operation of the fan 300, thereby providing heat dissipation to the carrier 100. In addition, the temperature at both ends of the carrier 100 can be detected by the first temperature control device 410 and the second temperature control device 420, and the controller 500 controls the fan 300 to rotate forward or reverse according to the temperature at both ends of the carrier 100, so that the direction of the airflow can be repeatedly switched to guide the airflow to flow along the carrier 100 from both ends of the carrier 100, so that the heat dissipation effect at both ends of the carrier 100 is roughly the same, thereby achieving the purpose of uniform heat dissipation of the carrier 100, and improving the deformation problem caused by uneven heat dissipation in the prior art.
