A focusing sleeve 210 is fitted onto the focusing fastener 202. The focusing sleeve 210 is located between the first mounting bracket 170 and the focusing mounting wall 220 of the focusing bracket 140 to define their relative positions. Focusing sleeves 210 of different lengths can be replaced to adjust the gap between the first mounting bracket 170 and the focusing mounting wall 220 of the focusing bracket 140. In other words, the focusing sleeve 210 is located between the focusing placement frame 140 and the focusing mounting wall 220 to define the relative positions of the focusing placement frame 140 and the focusing mounting wall 220. Focusing sleeves 210 of different lengths can be replaced to adjust the size of the gap between the focusing placement frame 140 and the focusing mounting wall 220.

Different length sizes of the first homogenization sleeve 211 can be replaced to adjust the size of the gap between the second placement rack 171 of the second homogenization placement rack 160 and the first placement rack 170 of the first homogenization placement rack 150. That is, the first homogenization sleeve 211 is located between the first homogenization placement rack 150 and the second homogenization placement rack 160 to define the relative position of the first homogenization placement rack 150 and the second homogenization placement rack 160. Different length sizes of the first homogenization sleeve 211 can be replaced to adjust the size of the gap between the first homogenization placement rack 150 and the second homogenization placement rack 160.

[0075] The second homogenization sleeve 212 is located between the second placement rack 171 of the first homogenization placement rack 150 and the light condensing mounting wall 220 to define the relative position of the second placement rack 171 of the first homogenization placement rack 150 and the light condensing mounting wall 220. Different length sizes of the second homogenization sleeve 212 can be replaced to adjust the size of the gap between the second placement rack 171 of the first homogenization placement rack 150 and the light condensing mounting wall 220. That is, the second homogenization sleeve 212 is located between the first homogenization placement rack 150 and the light condensing mounting wall 220 to define the relative position of the first homogenization placement rack 150 and the light condensing mounting wall 220. Different length sizes of the second homogenization sleeve 212 can be replaced to adjust the size of the gap between the first homogenization placement rack 150 and the light condensing mounting wall 220.

[0076] It should be noted that when the homogenization fastener 203 is tightened, the first placement rack 170 and the second placement rack 171 of the second homogenization placement rack 160 clamp the second homogenization lens 161, and the first placement rack 170 and the second placement rack 171 of the first homogenization placement rack 150 clamp the first homogenization lens 151. At this time, the second homogenization lens 161 defines the relative position between the first placement rack 170 and the second placement rack 171 of the second homogenization placement rack 160, and the first homogenization lens 151 defines the relative position between the first placement rack 170 and the second placement rack 171 of the first homogenization placement rack 150.

[0077] When the spotlight fastener 202 is tightened, the first placement rack 170 and the second placement rack 171 of the spotlight placement rack 140 clamp the spotlight lens 141. At this time, the spotlight lens 141 defines the relative positions of the first placement rack 170 and the second placement rack 171 of the spotlight placement rack 140.

[0078] Optionally, the laser fastener 200, the base fastener 201, the spotlight fastener 202, and the homogenization fastener 203 are all bolts.

[0079] As shown in Figure 1 and Figure 2 , the spotlight body 221 has a strip long hole 131 (one example of a long hole). The long diameter of the strip long hole 131 is parallel to the adjustment direction D. The mounting base 110 has a base long hole 111 (another example of a long hole). The long diameter of the base long hole 111 is parallel to the adjustment direction D. It should be noted that the size of the long hole in the extension direction of its long diameter is the largest size of the long hole.

[0080] The heating device further comprises the base fastener 201. The base fastener 201 connects the nut after passing through the strip long hole 131 and the base long hole 111, so as to connect the lens base 130 and the mounting base 110, thereby making the lens base 130 adjustably connected to the mounting base 110 along the adjustment direction D. Thus, the structure of the heating device is simple. In addition, the strip long hole 131 and the base long hole 111 can guide the movement of the lens base 130 relative to the mounting base 110 along the adjustment direction D.

[0081] It can be understood that in an embodiment not shown, one of the spotlight body and the mounting base is provided with a through hole, and the other is provided with a long hole, so that the lens base is adjustably connected to the mounting base along the adjustment direction.

[0082] Optionally, as shown in Figure 1 and Figure 2 , each laser placement rack 120 comprises an upper laser placement rack 126 and a lower laser placement rack 127.

The upper laser placement rack 126 has an upper arc-shaped notch. The lower laser placement rack 127 has a lower arc-shaped notch.

[0083] The upper laser placement rack 126 is located above the lower laser placement rack 127. The upper laser placement rack 126 is connected to the lower laser placement rack 127. At this time, the upper arc-shaped notch and the lower arc-shaped notch of the first laser placement rack 121 form the first laser mounting hole 123. The upper arc-shaped notch and the lower arc-shaped notch of the second laser placement rack 122 form the second laser mounting hole 124. In this way, the upper laser placement rack 126 and the lower laser placement rack 127 clamp the laser 125. Thus, the installation of the laser 125 is facilitated.

[0084] Optionally, as shown in Figure 1 and Figure 2 The heating device further comprises a laser fastener 200. The lower laser placement rack 127 has a laser through hole. The upper laser placement rack 126 has a laser threaded hole. After the laser fastener 200 passes through the base long hole 111 and the laser through hole, it is screwed to the laser threaded hole, so that the upper laser placement rack 126 and the lower laser placement rack 127 are connected by the laser fastener 200, and are connected to the mounting base 110, so that the laser placement rack 120 is adjustable along the adjustment direction D relative to the mounting base 110. Thus, the heating device has fewer parts and simple structure. In addition, the provision of the base long hole 111 can guide the movement of the laser placement rack 120 along the adjustment direction D relative to the mounting base 110.

[0085] In this way, the relative positions of the first homogenizing lens 151, the second homogenizing lens 161, the condensing lens 141, the laser 125 and the prepreg 180 can be adjusted according to the parameters of the first homogenizing lens 151, the parameters of the second homogenizing lens 161, the parameters of the condensing lens 141 and the parameters of the laser 125, so that the energy of the laser 190 is more uniform.

[0086] When the parameters of the first homogenizing lens 151, the parameters of the second homogenizing lens 161, the parameters of the condensing lens 141 and the parameters of the laser 125 do not change, the relative positions of the first homogenizing lens 151, the second homogenizing lens 161, the condensing lens 141, the laser 125 and the prepreg 180 remain unchanged. At this time, it is not necessary to adjust the positions of the laser placement rack 120, the lens base 130, the condensing placement rack 140, the first homogenizing placement rack 150 and the second homogenizing placement rack 160.

[0087] After at least one of the parameters of the first homogenizing lens 151, the parameters of the second homogenizing lens 161, the parameters of the condensing lens 141 and the parameters of the laser 125 changes, it is necessary to readjust the relative positions of the laser placement rack 120, the lens base 130, the condensing placement rack 140, the first homogenizing placement rack 150 and the second homogenizing placement rack 160.

[0088] Optionally, as shown in Figure 1 and Figure 2As shown, the lens holder has a first holder 170 and a second holder 171. The first holder 170 and the second holder 171 are arranged in pairs. The first holder 170 and the second holder 171 arranged in pairs are used to clamp the lens. That is, the light condensing holder 140 includes the first holder 170 and the second holder 171 arranged in pairs. The first uniformization holder 150 includes the first holder 170 and the second holder 171 arranged in pairs. The second uniformization holder 160 includes the first holder 170 and the second holder 171 arranged in pairs. Thus, the lens is conveniently installed.

[0089] Optionally, the surfaces of the first holder 170 and the second holder 171 facing each other have a holding groove 172 in communication with the lens through hole 173. The holding groove 172 is used to accommodate the lens. Thus, the lens can be more stably fixed.
