The position of the aluminum substrate is such that the center of the LED particles on the aluminum substrate coincides with the expected center of the glass rod, and the expected center is the midpoint of the distance between the centers of the maximum allowable size and the minimum allowable size of the glass rod. By combining the positioning member and the fastening member to set the method for fixing the position of the aluminum substrate provided with a plurality of LED particles, and by combining the positioning member, the fastening member, and the pressing member to fix the position of the glass rod, the displacement space of the glass rod when displacement may occur is reduced, thereby reducing the deviation between the center of the glass rod and the center of the LED particles.

Description

Technical Field

[0001] The present application relates to the field of industrial vision technology, and particularly relates to a light source device and a manufacturing method thereof. Background Art

[0002] Industrial vision technology is a rapidly developing branch technology in artificial intelligence. Industrial vision technology collects images by a machine simulating the human eye, and performs image processing and analysis through software to obtain an analysis result. The quality of image collection is an important factor affecting the analysis result. During the process of image collection, the light source device emits visible light, which has an important impact on the quality of image collection and is one of the core devices of industrial vision technology.

[0003] As Figure 1a shown, the commonly used light source device includes an LED particle 110, an aluminum substrate 120, a glass rod 130, an acrylic plate 140, and a glass rod positioning member 150. Among them, the LED particle 110 is fixed on the aluminum substrate 120, the glass rod 130 is fixed by the glass rod positioning members 150 on both sides thereof, and the acrylic plate 140 is located above the glass rod 130. The center 111 of the LED particle 110 needs to coincide with the center 131 of the glass rod 130 to ensure the light-emitting performance of the light source device. The method for realizing the coincidence of the center 111 of the LED particle and the center 131 of the glass rod includes: First, by fixing the aluminum substrate 120, the position of the LED particle 110 on the aluminum substrate 120 is fixed; then, the positions of the glass rod positioning members 150 on both sides of the glass rod 130 are determined so that the center of the distance between the two glass rod positioning members 150 coincides with the center 111 of the LED particle; finally, the glass rod 130 is fixed by engaging the arc-shaped groove of the glass rod positioning member 150.

[0004] As Figure 1b shown, in actual production, the glass rod 130 has dimensional tolerances, and the size of the glass rod 130 may be any size within the range from the minimum allowable size of the glass rod to the maximum allowable size of the glass rod. The size of the glass rod positioning member 150 matches the maximum allowable size of the glass rod, so that the glass rod positioning member 150 can fasten the glass rod 133 with the maximum allowable size.

[0005] However, as Figure 1b and Figure 1c shown, when the size of the glass rod 130 is the minimum allowable size of the glass rod, the size of the glass rod 132 with the minimum allowable size is smaller than the fastening size of the glass rod positioning member 150, which easily causes the glass rod 132 with the minimum allowable size to shift within the glass rod positioning member 150, and may further cause a large deviation between the center 131 of the glass rod and the center 111 of the LED particle. Summary of the Invention

Detailed implementation manners

[0046] To enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0047] To facilitate the description of the technical solutions of the application, some concepts involved in this application will be described first below.

[0050] The first tightening hole 172 and the second tightening hole 201 are round holes with the same diameter.

[0051] The first vertex angle 211 and the second vertex angle 212 are two different vertex angles, and there is a groove provided below the second vertex angle 212.

[0052] See Figure 2a and Figure 2b, an embodiment of the present application provides a light source device, including an aluminum substrate 120 and a glass rod 130. A plurality of aluminum substrates 120 are arranged below the glass rod 130. The length of the glass rod 130 is the same as the sum of the lengths of the plurality of aluminum substrates 120. A plurality of LED particles 110 are fixedly arranged on the aluminum substrate 120. It is characterized in that it further includes: a positioning member 160 arranged on one side of the glass rod 130, a plurality of fastening members 170 arranged on the other side of the glass rod 130, and a heat dissipation profile 210 arranged directly below the aluminum substrate 120. The length of the heat dissipation profile 210 is the same as the sum of the lengths of the plurality of aluminum substrates 120; a first groove 161 is arranged on the side of the positioning member 160 facing the glass rod 130, and a first notch 162 is arranged on the lower part of the side of the positioning member 160 facing the aluminum substrate 120; a second groove 171 is arranged on the side of the fastening member 170 facing the glass rod 130. A first tightening hole 172 penetrating the fastening member 170 horizontally is arranged on the inner wall of the second groove 171. A tightening member 173 is arranged in the first tightening hole 172. The tightening member 173 is used to adjust the length of its protrusion from the second groove 171 to tighten the glass rod 130. A second notch 174 is arranged on the lower part of the side of the fastening member 170 facing the glass rod 130; the first groove 161 and the second groove 171 are engaged with both sides of the glass rod 130, and both the first notch 162 and the second notch 174 are used to fix the aluminum substrate 120 directly above the heat dissipation profile 210.

[0053] By combining the positioning member 160 and the fastening member 170 to set the position of the aluminum substrate 120 on which a plurality of the LED particles 110 are fixedly arranged, and by combining the positioning member 160, the fastening member 170 and the tightening member 173 to fix the position of the glass rod 130, the displacement space of the glass rod 130 when displacement may occur is reduced, thereby reducing the deviation between the center of the glass rod 130 and the center of the LED particles 110.

[0054] In some embodiments, such as Figure 3a , Figure 3b and Figure 3c shown, the first groove 161 can be selected from any one of a rectangular groove, an arc groove and a triangular groove, and the second groove 171 can be selected as an arc groove. The first groove 161 and the second groove 171 are engaged with both sides of the glass rod 130.

[0055] In some embodiments, when the tightening member 173 is a screw-in type tightening member, such as Figure 4a , Figure 4b and Figure 4cAs shown in the figure, the pressing member 173 can be optionally any one of a set screw with threads, a screw, and a combination of a screw and a squeezing block. When the pressing member 173 is a combination of a screw and a squeezing block, the fastener 170 is close to the glass rod 130 and is provided with a squeezing block groove inside for fixing the squeezing block. The center of the squeezing block and the center of the first pressing hole 172 are on the same horizontal straight line. Place the squeezing block into the squeezing block groove from the side close to the glass rod 130, and rotate the pressing member 173 that sequentially passes through the second pressing hole 201 and the first pressing hole 172, so as to push the squeezing block to move by adjusting the length of the pressing member 173 extending out of the second groove 171 itself, and then press the glass rod 130 through the squeezing block. The width of the squeezing block groove matches the extending range of the pressing member 173, so that when adjusting the maximum length of the pressing member 173 extending out of the second groove 171 to push the squeezing block to move to the maximum length, the squeezing block groove can still fix the squeezing block and prevent the squeezing block from falling out of the squeezing block groove.

[0056] In some embodiments, on the upper part of the side of the fastener 170 facing the glass rod 130, a third notch 175 is provided, and a sealing support strip 180 is arranged in the third notch 175. The width of the sealing support strip 180 matches the width of the third notch 175, the length of the sealing support strip 180 is the same as the length of the glass rod 130, and the sealing support strip 180 is used to adjust the positions of multiple fasteners 170 to be aligned, so that the third notch 175 of each fastener 170 fits with the sealing support strip 180. Furthermore, by improving the neatness of the positions of multiple fasteners 170, the uniformity of the clamping effect of multiple fasteners 170 on the glass rod 130 and the fixing effect on the aluminum substrate 120 is improved, and thus the clamping effect of multiple fasteners 170 on the glass rod 130 and the fixing effect on the aluminum substrate 120 are improved.

One end of the acrylic board 140 is arranged above the positioning member 160, the other end of the acrylic board 140 is arranged above the sealing support strip 180. The upper surface of the positioning member 160 and the upper surface of the sealing support strip 180 are in the same horizontal plane. The length of the acrylic board 140 is the same as the length of the glass rod 130, and the sum of the height of the acrylic board 140 and the height of the sealing support strip 180 matches the height of the third notch 175. The positioning member 160 and the sealing support strip 180 jointly support the acrylic board 140 to make the acrylic board 140 in a horizontal state, and the position of one end of the acrylic board 140 close to the third notch 175 can be fixed through the third notch 175.

[0058] In some embodiments, one end of the acrylic board 140 is aligned with the side of the positioning member 160 away from the glass rod 130, and the other end of the acrylic board 140 is aligned with the side where the sealing support strip 180 and the third notch 175 are in contact.

[0059] In some embodiments, a sealing strip 190 is further included.

The sealing strip 190 is used to tightly press the positioning member 160 and one end of the acrylic plate 140 near the positioning member 160 together.

[0060] By aligning one end of the acrylic plate 140 with the surface of the positioning member 160 away from the glass rod 130, the convenience of installing the sealing strip 190 and the conformity of the sealing strip 190 with the upper surface of the acrylic plate 140, the surface of the positioning member 160 away from the glass rod 130, and the surface of the acrylic plate 140 near one end of the positioning member 160 are improved. Furthermore, by improving the conformity, the sealing effect of the sealing strip 190 and the effect of fixing the positioning member 160 and the acrylic plate 140 are improved.

[0061] In some embodiments, a plurality of protective covers 200 are further included. The protective covers 200 are in contact with the upper surface of the fastener 170, the upper surface of the acrylic plate 140, and the surface of the fastener 170 away from the glass rod 130. The protective covers 200 are used to fix the sealing support strip 180 and one end of the acrylic plate 140 near the fastener 170 in the third notch 175.

[0062] By aligning the other end of the acrylic plate 140 with the side where the sealing support strip 180 and the third notch 175 are in contact, the convenience of installing the plurality of protective covers 200 and the conformity of the protective covers 200 with the upper surface of the fastener 170, the upper surface of the acrylic plate 140, and the surface of the fastener 170 away from the glass rod 130 are improved. Furthermore, by improving the conformity, the dust-proof effect of the protective covers 200 and the fixing effect on the sealing support strip 180, the acrylic plate 140, and the fastener 170 are improved.

[0063] In some embodiments, a second tightening hole 201 is further included. The second tightening hole 201 penetrates through the protective cover 200. The second tightening hole 201 is arranged in parallel with the first tightening hole 172, and the radius of the second tightening hole 201 is the same as the radius of the first tightening hole 172. So that the tightening member 173 can sequentially pass through the second tightening hole 201 and the first tightening hole 172 and tighten the glass rod 130.

[0064] In some embodiments, when the pressing member 173 is a screwed-in pressing member, and the pressing member 173 is any one of a setscrew, a screw, and a combination of a screw and a squeezing block, threads are provided on the inner surface of the second pressing hole 201 and the inner surface of the first pressing hole 172. The threads on the inner surface of the second pressing hole 201 and the inner surface of the first pressing hole 172 match the threads of the pressing member 173 to engage with the threads of the pressing member 173.

[0065] In some embodiments, a first top angle 211 is provided at the top of the heat dissipation profile 210. A fourth notch 163 is provided at the bottom of the side of the positioning member 160 facing the glass rod 130. The fourth notch 163 matches the shape of the first top angle 211, and the fourth notch 163 is used to fit with the first top angle 211.

[0066] In some embodiments, a second top angle 212 is provided at the top of the heat dissipation profile 210.

The fifth notch 176 matches the shape of the second top angle 212, and the fifth notch 176 is used to fit with the second top angle 212.

[0067] By means of the fourth notch 163 of the positioning member 160 matching the shape of the first top angle 211 of the heat dissipation profile 210, and by means of the fifth notch 176 of the fastening member 170 matching the shape of the second top angle 212 of the heat dissipation profile 210, the positioning member 160 and the fastening member 170 are both fitted to the heat dissipation profile 210. Compared with the case where the positioning member 160 and the fastening member 170 are not fitted to the heat dissipation profile 210, the heat dissipation effect of the light source device is improved.

[0068] As can be seen from the above embodiments, a light source device provided by an embodiment of the present application fixes the position of the glass rod by combining the first groove of the positioning member, the second groove of the fastening member, and the first pressing member provided in the pressing hole of the fastening member. The position of the aluminum substrate is fixed by the first notch of the positioning member and the second notch of the fastening member. The position of the aluminum substrate is such that the center of the LED particles on the aluminum substrate coincides with the predicted center of the glass rod. The predicted center is the midpoint of the distance between the centers of the maximum allowable size and the minimum allowable size of the glass rod. By combining the positioning member and the fastening member to set the position of the aluminum substrate provided with a plurality of the LED particles, and by combining the positioning member, the fastening member, and the pressing member to fix the position of the glass rod, the displacement space of the glass rod when displacement may occur is reduced, thereby reducing the deviation between the center of the glass rod and the center of the LED particles.

[0071] Step S520: Install the same side of multiple aligned aluminum substrates to fit with the inner surface of the first notch of the positioning member. Multiple LED particles are fixedly arranged on the aluminum substrates.

[0072] Step S530: Rotate the structure composed of the positioning member, the heat dissipation profile, and multiple aluminum substrates 90 degrees in the direction away from the first notch of the positioning member, so as to install one side of the glass rod to engage with the first groove of the positioning member.

[0073] Step S540: Install the second notch of the fastener to fit with the inner surface of the second notch and the other side of multiple aligned aluminum substrates, and install the second groove of the fastener to engage with the other side of the glass rod.

[0074] Step S550: Rotate the structure composed of the positioning member, the heat dissipation profile, multiple aluminum substrates, the glass rod, and the fastener 90 degrees in the direction away from the glass rod of the fastener, so as to install the sealing support strip into the third notch of the fastener.

[0075] Step S560: Install one end of the acrylic plate above the positioning member and the other end of the acrylic plate above the sealing support strip.

[0076] Step S570: Install the sealing strip to fit with the upper surface of the acrylic plate, the surface of the positioning member away from the glass rod, and the surface of the acrylic plate near the positioning member, and install multiple protective covers to fit with the upper surface of the fastener, the upper surface of the acrylic plate, and the surface of the fastener away from the glass rod.

[0077] Step S580: Install the tightening member to sequentially penetrate through the second tightening hole and the first tightening hole, so as to tighten the glass rod by adjusting the length of the tightening member extending out of the second groove.

[0078] A manufacturing method of a light source device provided by an embodiment of the present application fixes the position of a glass rod by combining a first groove of a positioning member, a second groove of a fastening member, and a first tightening member disposed in a tightening hole of the fastening member. The position of an aluminum substrate is fixed by a first notch of the positioning member and a second notch of the fastening member. The position of the aluminum substrate is such that the center of the LED particles on the aluminum substrate coincides with the predicted center of the glass rod. The predicted center is the midpoint of the distance between the centers of the maximum allowable size and the minimum allowable size of the glass rod. By combining the positioning member and the fastening member to set the method of fixing the position of the aluminum substrate provided with a plurality of the LED particles, and by combining the positioning member, the fastening member, and the tightening member to fix the position of the glass rod, the displacement space of the glass rod when displacement may occur is reduced, thereby reducing the deviation between the center of the glass rod and the center of the LED particles.
