Description

Technical Field

[0001] This utility model relates to the field of light source device technology, and in particular to a composite light source device. Background Technology

[0002] Common defects are inevitably generated during the production of photovoltaic glass substrates, such as bubbles, open bubbles, stones, unevenness, and roll marks. Further scratches on the top and bottom surfaces can occur during downstream production. To ensure the safety and performance requirements of photovoltaic glass, defect detection is necessary before shipment to prevent greater losses.

[0003] Currently, the commonly used automated inspection method involves using industrial vision inspection equipment. This method utilizes multiple light sources at a single workstation, flashing in different ways to reveal the different characteristics of various defects, thus achieving defect detection. Existing solutions use light sources including low-angle transmitted light sources and direct-transmitted light sources, with the low-angle transmitted light source located to one side of the direct-transmitted light source. This arrangement results in excessive space occupied by the light sources. Since most glass factories use roller conveyors to transport glass sheet by sheet, this method increases the distance between two rollers, creating significant gaps in the production line. When glass passes between adjacent rollers, the glass head and tail exhibit noticeable shaking and slippage, causing the glass head and tail to appear bent and deformed in the images captured by the vision inspection equipment. This significantly impacts defect detection and dimensional measurement. Utility Model Content

[0065] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0066] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0067] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0069] The current common automated inspection method for photovoltaic glass is to use industrial vision inspection equipment. This method uses multiple light sources at a single workstation, each illuminated in different ways, to flash and reveal the different characteristics of various defects, thus achieving defect detection. Existing solutions use both low-angle transmitted light sources and direct-transmitted light sources, with the low-angle transmitted light source located to one side of the direct-transmitted light source. This arrangement results in excessive space occupied by the light sources. Since most glass factories use roller conveyors to transport glass sheet by sheet, this method increases the distance between two rollers, creating significant gaps in the production line. When the glass passes between adjacent rollers, the glass head and tail exhibit noticeable shaking and slippage, causing the glass head and tail to appear bent and deformed in the images captured by the vision inspection equipment. This significantly impacts defect detection and dimensional measurement.

[0070] To solve the above problems, such as Figures 1-5As shown, this embodiment provides a composite light source device, including a support and fixing component 1 and a light source component 3. The support and fixing component 1 has a receiving cavity. The light source component 3 is disposed within the receiving cavity and is supported and fixed to the support and fixing component 1. The light source component 3 includes a direct-transmittance light source component 31 and a low-transmittance light source component 32. The low-transmittance light source component 32 is inclinedly disposed on one side of the direct-transmittance light source component 31. Both the direct-transmittance light source component 31 and the low-transmittance light source component 32 face the same side of the support and fixing component 1, and the light from both components is emitted from the same side of the support and fixing component 1. This composite light source device, by placing the direct-transmittance light source component 31 and the low-transmittance light source component 32 within the same device, reduces the overall space occupied, lowers defect detection errors, and improves defect detection accuracy.

[0071] Preferably, the angle formed by the tilt of the low-transmittance light source component 32 and the direct-transmittance light source component 31 is α, and the value of α ranges from 20° to 50°. This setting can effectively detect glass scratches and bubbles. α can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, etc.

[0072] Specifically, such as Figure 4 As shown, the supporting and fixing assembly 1 includes a heat dissipation support assembly 11 and a cover plate assembly 12. The direct-transmittance light source assembly 31 is supported and fixed to the heat dissipation support assembly 11. A heat dissipation channel is provided inside the heat dissipation support assembly 11, and a cooling medium flows through the heat dissipation channel. In this embodiment, the cooling medium is cooling water, which is low in cost and pollution-free. Part of the structure of the heat dissipation support assembly 11 extends into the cover plate assembly 12, and the cover plate assembly 12 and the heat dissipation support assembly 11 are connected to form a receiving cavity. The low-transmittance light source assembly 32 is disposed between the cover plate assembly 12 and the heat dissipation support assembly 11, and the low-transmittance light source assembly 32 is in contact with the heat dissipation support assembly 11. The heat dissipation support assembly 11 and the cover plate assembly 12 can support and fix the light source assembly 3. In addition, the cooling medium flowing through the heat dissipation channel inside the heat dissipation support assembly 11 can cool and dissipate heat from the light source assembly 3, thereby extending the service life of the light source assembly 3.

[0073] Furthermore, such as Figure 4 As shown, the heat dissipation support assembly 11 includes a first heat dissipation profile 111 and a second heat dissipation profile 112 spaced apart. Both the first heat dissipation profile 111 and the second heat dissipation profile 112 have flow channels. The two ends of the first heat dissipation profile 111 and the second heat dissipation profile 112 are connected by a connecting member 113 (see [link]). Figure 5 One of the first heat dissipation profile 111 and the second heat dissipation profile 112 is connected to the water inlet 4, and the other is connected to the water outlet 5. The flow channel, the connecting part 113, the water inlet 4, and the water outlet 5 form a heat dissipation channel. Specifically, as shown in... Figure 6As shown, the connecting member 113 is provided with a water inlet channel 1131 and a water outlet channel 1132. One of the first heat dissipation profile 111 and the second heat dissipation profile 112 is connected to the water inlet channel 1131, and the other is connected to the water outlet channel 1132. The water inlet channel 1131 is connected to the water inlet 4, and the water outlet channel 1132 is connected to the water outlet 5. A direct-transmittance light source assembly 31 is disposed between the first heat dissipation profile 111 and the second heat dissipation profile 112. The second heat dissipation profile 112 is connected to the cover plate assembly 12 to form a receiving cavity. The first heat dissipation profile 111 is placed in the receiving cavity. A low-transmittance light source assembly 32 is disposed between the cover plate assembly 12 and the first heat dissipation profile 111.

[0074] like Figure 4 and Figure 5 As shown, the cover assembly 12 includes a base plate 121, a side plate 122, and a transparent protective cover plate 123. The first heat dissipation profile 111 and the second heat dissipation profile 112 are supported on the base plate 121. In this embodiment, the first heat dissipation profile 111 and the second heat dissipation profile 112 are provided with first fixing holes every 50mm-75mm along their length direction. The base plate 121 is provided with second fixing holes corresponding to the first fixing holes of the first heat dissipation profile 111 and the second heat dissipation profile 112. The first heat dissipation profile 111 and the second heat dissipation profile 112 are firmly fixed to the base plate 121 by means of fasteners passing through the corresponding first fixing holes and second fixing holes. Side plate 122 is disposed on the side of the first heat dissipation profile 111 facing away from the second heat dissipation profile 112; transparent protective cover plate 123 is disposed on the top of side plate 122 and heat dissipation support assembly 11, and transparent protective cover plate 123 and side plate 122 are connected by support structure 124; low-transmittance light source assembly 32 is disposed between support structure 124 and first heat dissipation profile 111, and direct-transmittance light source assembly 31 and low-transmittance light source assembly 32 are disposed facing transparent protective cover plate 123, and the light from direct-transmittance light source assembly 31 and low-transmittance light source assembly 32 is emitted through transparent protective cover plate 123. The aforementioned cover plate assembly 12 can cooperate with heat dissipation support assembly 11 to form a receiving cavity for accommodating light source assembly 3, so as to facilitate the accommodation and installation of light source assembly 3.

[0075] Furthermore, such as Figure 5 and Figure 7 As shown, the cover assembly 12 also includes support positioning members 125. Support positioning members 125 are provided at both ends of the heat dissipation support assembly 11. The support positioning members 125 are supported on the base plate 121 and abut against the first heat dissipation profile 111. The support structure 124 is supported and fixed on the support positioning members 125. The provision of support positioning members 125 facilitates the support and positioning of the support structure 124.

[0076] Specifically, the support positioning component 125 includes a support portion 1251 and a fixing portion 1252. The support portion 1251 is supported on the base plate 121; the fixing portion 1252 is connected to the support portion 1251 and abuts against the first heat dissipation profile 111. The support structure 124 supports and is fixed to the fixing portion 1252. The support positioning component 125 is supported on the base plate 121 via the support portion 1251, and the fixing portion 1252 is connected to the support portion 1251. The fixing portion 1252 can support and fix the support structure 124 to ensure the rapid installation of the support structure 124 and its stability after installation.

[0077] Optionally, such as Figure 5 As shown, the cover assembly 12 also includes a support member 126. One end of the support member 126 supports and connects to the support structure 124, and the other end is connected to the first heat dissipation profile 111. The support member 126 provides good support for the support structure 124 and prevents deformation of the support structure 124. In this embodiment, multiple support members 126 are spaced apart along the length of the support structure 124 to effectively prevent deformation. The specific number of support members 126 can be set according to requirements and is not specifically limited here.

[0078] Optionally, such as Figure 4 As shown, a transition strip 127 is provided between the base plate 121 and the side plate 122. An annular seal is provided at the installation position of the side plate 122, specifically between the side plate 122 and the support structure 124, the transition strip 127, and the support positioning member 125. The transition strip 127 facilitates the connection between the base plate 121 and the side plate 122, and the seal provides a seal to the receiving cavity, preventing dust and impurities from entering and providing good dust protection for the structural components within the cavity. In this embodiment, slots are provided at the installation positions of the side plate 122 and the transparent protective cover 123 to accommodate the seal. The seal is preferably a silicone foam strip. Two sleeved slots are provided at the installation position of the transparent protective cover 123. A special sealant is added to the outer slot to form a silicone foam strip, while the inner slot prevents excessive sealant from seeping into the receiving cavity.

[0079] like Figure 5 As shown, the cover assembly 12 also includes an end cover 128, which covers both ends of the heat dissipation support assembly 11 and the cover assembly 12, and a sealing gasket 129 is provided between the end cover 128 and the heat dissipation support assembly 11 and the cover assembly 12. The end cover 128 can seal the receiving cavity, and the sealing gasket 129 provides a better sealing effect.

[0080] In this embodiment, the sealing gasket 129 is made of conductive foam. In this embodiment, the contact surfaces of all parts are untreated (the contact surfaces are not conductive). Grounding threaded holes are provided on the first heat dissipation profile 111. The grounding threaded holes are connected to the grounding wire to prevent static electricity from being generated inside the device and forming a short circuit.

[0081] like Figure 5 , Figure 8 and Figure 9 As shown, the composite light source device also includes a mounting and positioning component 13. The mounting and positioning component 13 includes a mounting plate 131, a first positioning part 132, and a second positioning part 133. The first positioning part 132 and the second positioning part 133 are respectively disposed on both sides of the mounting plate 131. The first positioning part 132 is disposed on the side of the mounting plate 131 facing the heat dissipation support component 11. The end cover plate 128 is provided with a through positioning hole. The first positioning part 132 passes through and is confined within the through positioning hole. One of the first positioning part 132 and the connecting member 113 is provided with a positioning protrusion 1133, and the other is provided with a positioning groove 1321. The positioning protrusion 1133 and the positioning groove 1321 are inserted and engaged to realize the installation and positioning of the first positioning part 132.

In this embodiment, the positioning groove 1321 is disposed on the first positioning part 132, and the positioning protrusion 1133 is disposed on the connecting member 113. The positioning protrusion 1133 has a plate-like structure. Of course, the positioning groove 1321 can also be disposed on the connecting member 113, and the positioning protrusion 1133 can be disposed on the first positioning part 132.

Both the low-transmittance light source 321 and the second condensing lens 322 are inclined and spaced apart.

[0083] The direct-transmittance light source assembly 31 can concentrate the light of the direct-transmittance light source 311 through the first condensing lens 312, thereby improving the light output efficiency; and the light uniform plate 313 makes the light more uniform. The low-transmittance light source assembly 32 can concentrate the light of the low-transmittance light source 321 through the second condensing lens 322, thereby improving the light output efficiency.

[0084] like Figure 10 and Figure 11As shown, the first heat dissipation profile 111 includes a first heat dissipation body 1111 and a first heat dissipation bracket 1112. The first heat dissipation body 1111 is disposed on the first heat dissipation bracket 1112, and a first flow channel 11110 is provided inside the first heat dissipation body 1111. Figure 12 As shown, the second heat dissipation profile 112 includes a second heat dissipation body 1121 and a second heat dissipation bracket 1122. The second heat dissipation body 1121 is disposed on the second heat dissipation bracket 1122. Each of the second heat dissipation bodies 1121 has a second flow channel 11210, and the first flow channel 11110 and the second flow channel 11210 are connected. Figure 13 As shown, the first heat dissipation bracket 1112 and the second heat dissipation bracket 1122 have mounting grooves on opposite sides. The mounting groove on the first heat dissipation bracket 1112 is the first mounting groove 11120, and the mounting groove on the second heat dissipation bracket 1122 is the second mounting groove 11220. The support and fixing assembly 1 also includes a limiting frame 14, with both ends of the limiting frame 14 respectively confined within the corresponding first mounting groove 11120 and second mounting groove 11220. The limiting frame 14 prevents the first heat dissipation profile 111 and the second heat dissipation profile 112 from twisting due to excessive length. The power cord and signal cord connected to the direct-transmitting light source 311 pass through the limiting frame 14.

[0085] Furthermore, such as Figure 10 and Figure 11As shown, the first heat dissipation body 1111 has a first limiting groove 11111 and a second limiting groove 11112 on the side facing the second heat dissipation body 1121. The second limiting groove 11112 is located above the first limiting groove 11111. The second heat dissipation body 1121 has a third limiting groove 11211 and a fourth limiting groove 11212 on the side facing the first heat dissipation body 1111. The fourth limiting groove 11212 is located above the third limiting groove 11211. The first limiting groove 11111 and the third limiting groove 11211 are correspondingly arranged, and the second limiting groove 11112 and the fourth limiting groove 11212 are correspondingly arranged. The bottom of the first heat dissipation body 1111 has a first groove 11115. The bottom of the first groove 11115 and the side facing the second heat dissipation body 1121 have openings. The bottom of the second heat dissipation body 1121 has a second groove 11213. The bottom of the second groove 11213 and the side facing the first heat dissipation body 1111 have openings. The first groove 11115 and the second groove 11213 form a limiting groove. The direct-transmitting light source 311 is limited within the limiting groove and is in contact with the first heat dissipation body 1111 and the second heat dissipation body 1121. The lamp bead of the direct-transmitting light source 311 is located between the first heat dissipation body 1111 and the second heat dissipation body 1121. The positioning protrusions 1133 of the connecting parts 113 at both ends of the first heat dissipation profile 111 and the second heat dissipation profile 112 are limited within the limiting groove and abut against the end of the direct-transmitting light source 311 to limit the end of the direct-transmitting light source 311. The direct-transmitting light source 311 is positioned by the cooperation of the limiting groove and the positioning protrusion 1133 of the connecting member 113, and is also cooperated with the mounting positioning member 13 through the connecting member 113. This allows the accuracy of the direct-transmitting light source 311 to be transmitted through the positioning protrusion 1133 of the connecting member 113 and the first positioning part 132 and the second positioning part 133 of the mounting positioning member 13, thus ensuring the positioning accuracy of the composite light source device.

[0086] The first condensing lens 312 is respectively positioned within the first limiting groove 11111 and the third limiting groove 11211 on both sides, and the light-diffusing plate 313 is respectively positioned within the second limiting groove 11112 and the fourth limiting groove 11212 on both sides. The first heat dissipation body 1111 has a fifth limiting groove 11113 and a sixth limiting groove 11114 on the side opposite to the second heat dissipation body 1121, with the sixth limiting groove 11114 located above the fifth limiting groove 11113.

[0087] like Figure 14As shown, a seventh limiting groove 1241 is provided on the side of the support structure 124 facing the first heat dissipation body 1111. The sixth limiting groove 11114 and the seventh limiting groove 1241 are arranged opposite to each other. One side of the low-transmittance light source 321 is limited in the fifth limiting groove 11113, and the other side is attached to the bottom surface of the support structure 124. The two sides of the second condenser lens 322 are respectively limited in the sixth limiting groove 11114 and the seventh limiting groove 1241.

[0088] like Figure 2 As shown, the base plate 121 has three cable outlets 1211. Power cables connected to the direct-transmitting light source 311, power cables connected to the low-transmitting light source 321, and signal cables connected to both the direct-transmitting and low-transmitting light sources 311 each exit through one cable outlet 1211. It should be noted that the number of cable outlets 1211 on the base plate 121 is not limited to three. The cable exit method for the power cables connected to the direct-transmitting light source 311, the low-transmitting light source 321, and the signal cables connected to both the direct-transmitting and low-transmitting light sources 311 is not limited to exiting through a single cable outlet 1211. The number and exit method of the cable outlets 1211 can be adjusted according to specific usage requirements.

[0089] Optionally, the first heat dissipation profile 111 is provided with fixing holes, and the aforementioned wire harness is secured to the first heat dissipation profile 111 by cable ties to achieve the functions of aesthetics, heat dissipation, and short circuit prevention. The specific number and position of the fixing holes can be set according to the requirements and are not specifically limited here.

[0090] Optionally, a vent valve 1212 is also provided on the base plate 121 to vent air and prevent excessive pressure in the cavity caused by heat dissipation of the light source component 3.
