[0031] Reference Figure 1-10 An embodiment of the utility model provides a strip substrate cooling device, which includes a cooling box 1 and a cooling fan 2 connected by a pipeline, wherein the cooling box 1 is provided with a plurality of cooling guide roller assemblies for conveying the substrate 5 on a strip basis, wherein the plurality of cooling guide roller assemblies are divided into three groups, wherein the cooling roller assemblies 15 in each group are transmitted by a belt 18, and one of the cooling roller assemblies 15 is connected to a first motor 17, wherein the main shaft of the first motor 17 drives the cooling roller assembly 15 to rotate when it rotates, thereby driving the remaining cooling roller assemblies 15 to rotate, thereby realizing the supporting and transmission function of the substrate 5 on a strip basis.

[0032] Specifically, refer to Figure 8 and Fig.10The cooling guide roller assembly includes a cooling roller 151, and first belt seat bearings 152 are provided at both ends of the cooling roller 151. The cooling roller 151 is installed on the side wall of the cooling box 1 through the first belt seat bearings 152. A pulley 153 is provided at one end of the cooling roller 151. The pulleys 153 in multiple cooling roller assemblies 15 are connected by a belt 18. One end of the pulley 153 provided on one of the cooling rollers 151 is connected to the main shaft of the first motor 17 through a coupling. When the first motor 17 is running, it drives the cooling roller 151 to rotate, and drives the remaining cooling rollers 151 to rotate under the transmission of the belt 18, so as to realize the support transmission of the substrate 5.

[0033] In this embodiment, refer to Figure 1-5 An air inlet 11 is provided at the bottom of the cooling box 1, and the air inlet 11 is connected to the air outlet of the air cooler 2 through the air inlet pipe 3. An air outlet is provided at the top of the cooling box 1, and the air outlet is connected to the air inlet 11 of the air cooler 2 through the return air pipe 4.

[0034] Further, see Figure 4-7 An upper cavity 14 and a lower cavity 12 are provided in the cooling box 1. The upper cavity 14 and the lower cavity 12 are respectively located at the upper and lower sides of the cooling guide roller assembly. The upper cavity 14 and the lower cavity 12 are both connected to the internal space of the cooling box 1.

[0035] Reference Figure 6 The lower cavity 12 includes a lower cavity main structure 121 and an air inlet plate 122 arranged on the top of the lower cavity main structure 121, and a plurality of air inlet holes 123 are arranged on the air inlet plate 122. The lower cavity 12 is connected with the internal space of the cooling box 1 through the air inlet holes 123. The air inlet 11 is arranged on the side wall of the lower cavity main structure 121. The cold air provided by the air cooler 2 enters the lower cavity 12 from the air inlet 11 after passing through the air inlet pipe 3, and then blows upward from the plurality of air outlet holes on the air outlet plate to enter the internal space of the cooling box 1 to cool the substrate 5.

[0036] Reference Figure 7 The upper cavity 14 includes an upper cavity main structure 141 and a return air plate 142 arranged at the bottom of the upper cavity main structure 141, and a plurality of return air holes 143 are arranged on the return air plate 142. The upper cavity 14 is connected with the internal space of the cooling box 1 through the return air holes 143. The air outlet is arranged on the side wall of the upper cavity main structure 141. The cold air blowing through the substrate 5 enters the lower cavity 12 from the return air holes 143 at the bottom of the upper cavity 14, and then enters from the return air port 13 and flows back to the air cooler 2 through the return air duct 4, thereby realizing the circulation of the cooling air.

[0037] Further, refer to Figure 4-7, the size of the lower cavity 12 at one end close to the air inlet 11 is larger than the size at the other end, that is, the internal space of the lower cavity 12 gradually narrows from one end of the lower cavity 12 close to the air inlet 11 to the other end. Since the air volume decreases at the end of the lower cavity 12 far from the air inlet 11, the air volume / wind speed is increased by reducing its space size, so that the air volume at the front and rear ends of the lower cavity 12 is more uniform, thereby improving the cooling effect of the substrate 5. The air outlet is located in the middle section of the upper cavity 14, and the sizes of the two ends of the upper cavity 14 are smaller than the sizes of the middle section of the upper cavity 14, thereby increasing the flow rate of the cold air at the two ends of the upper cavity 14 and improving the return air effect.

[0038] In this embodiment, a temperature sensor is provided in the cooling box 1, and the temperature in the cooling box 1 can be detected by the temperature sensor. When the temperature is higher than the set temperature, the PLC built into the cooling fan 2 will issue a command to adjust the temperature of the cold air output by the cooling fan 2. Figure 3 The air inlet duct 3 and the air return duct 4 are both provided with an air valve actuator 6 and an anemometer 7. The anemometer 7 can detect the speed of the cold air, that is, the air volume of the cold air flow, and then the air valve actuator 6 can adjust the air volume of the cooling box 1 in real time.

[0039] In this embodiment, refer to Figure 4 , Figure 5 and Fig. 9 The cooling box 1 is provided with a belt threading device 16, which is used for the substrate 5 to thread the belt along the plurality of cooling roller assemblies 15.

Figure 4 and Figure 8, each of the cooling rollers 151 is rotatably sleeved with the sprocket 164, and the sprocket 164 is connected to the cooling roller 151 through a deep groove ball bearing 154, so that the sprocket 164 can rotate on the cooling roller 151. The chain 165 is installed on the plurality of sprockets 164, the belt threading rod 163 is fixed on the chain 165, the second motor 161 is fixedly installed on the outside of the cooling box 1 through a motor mounting seat 167, the main shaft of the second motor 161 is connected to the belt threading guide roller 162 through a coupling, and the end of the belt threading guide roller 162 away from the second motor 161 is installed on the outside of the cooling box 1 through a second belt seat bearing 168, and the second motor 161 drives the belt threading guide roller 162 to rotate when it is running, thereby driving the operation of the chain 165. The cooling box 1 is provided with an inlet and an outlet for the substrate 5, and the tape threading guide roller 162 and the auxiliary guide roller 166 are respectively located at the inlet and the outlet for the substrate 5. When threading the tape, the substrate 5 is adhered to the tape threading rod 163, and then the second motor 161 drives the sprocket 164 to operate, and at the same time drives the chain 165 installed on the sprocket 164 to operate, thereby transmitting the substrate 5 to the inlet and outlet of the cooling box 1.

[0040] Furthermore, in order to improve the stability of the chain drive, two groups of chains 165 and sprockets 164 are provided correspondingly, and are respectively located at the front and rear ends of the belt guide roller 162, the auxiliary guide roller 166 and the cooling roller 151.
