[0023] Example 1

[0024] Reference Figures 1 to 3 A strip infrared curing production line, comprising a frame 1, on which a curing conveyor belt 11 and three cooling conveyor belts 12 are arranged, the curing conveyor belt 11 is arranged above the cooling conveyor belt 12, and a heating cover 2 is arranged above the curing conveyor belt 11, and an infrared lamp 21 is arranged in the heating cover 2;

[0025] In this embodiment, the curing conveyor belt 11 and the cooling conveyor belt 12 are both load-bearing roller tensioning belts. The belt body can be nylon, rubber or metal braid, which is sleeved outside the load-bearing roller. The friction force formed by the rotation of one or more load-bearing rollers is used to realize the operation load. As common knowledge, the load-bearing rollers at both ends of the conveyor belt are generally provided with tensioning devices, and the belt body of the conveyor belt is tightened by elastic devices or pre-tensioning force.

[0026] like Figure 1 As shown, in order to make the structure clear, Figure 1 The iron plate and half of the heating cover 2 on the observer's side are removed. The frame 1 includes iron plates on both sides, which are arranged on both sides of the conveyor belt. In order to facilitate observation and operation, multiple observation windows can be arranged on the iron plates. The two ends of the bearing roller are rotatably fixed on the iron plates on both sides, and the heating cover 2 is fixedly connected to the upper end of the iron plates through a bracket.

[0027] The end of the curing conveyor belt 1 (set to the right side in the figure in this embodiment) is provided with an elevator 3, and the elevator 3 includes a transfer conveyor belt 31 that can be raised and lowered, and is used to transfer the parts conveyed on the curing conveyor belt 11 to the cooling conveyor belt 12. It should be pointed out that the transfer conveyor belt 31 should be a bidirectional conveyor belt, and the cooling conveyor belt 12 is preferably a bidirectional conveyor belt.

[0028] The operation mode of this embodiment can be: at the starting end of the curing conveyor belt 1, the gluing production line is connected, and the parts after gluing are conveyed to the curing conveyor belt 1, and the temperature is increased under the action of the infrared lamp 21 to start curing. When it is conveyed to the end of the curing conveyor belt 1, the heating is completed and it is ready to cool. Under manual power switching or program control, the transfer conveyor belt 31 of the elevator 3 is aligned with the curing conveyor belt 1 and moves in the same direction, and the parts are transferred to the transfer conveyor belt 31. The transfer conveyor belt 31 stops running, moves downward to align with a cooling conveyor belt 12, and then moves in the opposite direction. The cooling conveyor belt 12 moves in the same direction as the current transfer conveyor belt 31, and the parts are transported to the starting end of the curing conveyor belt 1 for storage and cooling.

[0029] Example 2

[0030] The structure of this embodiment is substantially the same as that of embodiment 1. In order to further improve working efficiency, a first stroke sensing device 14 is provided at the end of the curing conveyor belt 11, a second stroke sensing device 13 is provided at the end of the cooling conveyor belt 12 away from the end of the curing conveyor belt 11, a temperature sensing device 15 and a counting device 16 are provided at the end of the cooling conveyor belt 12 close to the end of the curing conveyor belt 11, and a third stroke sensing device 33 is provided at the transfer conveyor belt 31.

[0031] The first stroke sensing device 14, the second stroke sensing device 13, and the third stroke sensing device 33 can be mechanical or electronic, and are preferably infrared sensing devices in this embodiment. The temperature sensing device 15 is a temperature sensor, and the counting device 16 is preferably a photoelectric counter, which is installed on a rack or cantilevered and fixed to the position where the parts on the conveyor belt pass. All sensing devices are connected to a PLC system or a computer motherboard and are controlled by programming.

[0032] The operation mode of this embodiment is as follows: when the operation of the heated parts is sensed by the first stroke sensing device, the transfer conveyor belt 31 of the elevator 3 is aligned with the curing conveyor belt 1 and moves in the same direction, and the parts are transferred to the transfer conveyor belt 31. When the third stroke sensing device 3 senses, the transfer conveyor belt 31 stops running, moves downward to align with a cooling conveyor belt 12, and then moves in the opposite direction. The cooling conveyor belt 12 moves in the same direction as the current transfer conveyor belt 31, and the parts are transferred to the cooling conveyor belt 12 and triggers the counting device 16. The counting device 16 records the number of parts on the cooling conveyor belt 12 plus one. When the second stroke sensing device 13 is triggered, the cooling conveyor belt 12 stops moving, and the temperature sensing device 15 on the cooling conveyor belt 12 It is set to start working. When the temperature sensing device 15 detects that the temperature in its detection area is lower than the preset threshold, it is marked as cooling completion. When the transfer conveyor 33 is idle, the cooling conveyor 12 runs in the direction of the elevator 3, and the transfer conveyor 33 is aligned with the cooling conveyor 12. When the parts trigger the counting device 16 at this time, the counting device 16 records the number of parts on the cooling conveyor 12 minus one, and the cooling conveyor 12 stops running. When the parts trigger the third stroke sensing device 33, the transfer conveyor 33 stops the alarm and waits for the workers to take away the parts. Or, when this embodiment is also coordinated with the packaging line, the parts continue to be conveyed to the packaging line. After the sensing device on the packaging line is triggered, the transfer conveyor 33 enters the next working cycle.

[0033] Example 3

[0034] This embodiment is substantially the same as Embodiment 1, except that the bearing roller comprises a main roller 112 and an auxiliary roller 11, wherein the auxiliary roller 111 is located below the main roller 112 and cooperates with the main roller 112 to press the belt body of the conveyor belt.

[0035] Both ends of the roller shaft of the auxiliary roller 111 are rotatably fixed on the iron plate through an arc groove 113. The arc groove 113 is a part of a circle, and the center of this circle is the roller shaft of the main roller 112 corresponding to the auxiliary roller 111. That is, when the position of the auxiliary roller 111 is adjusted along the arc groove 113, the auxiliary roller 111 actually revolves around the main roller 112. The advantage of this setting is that the belt body of the conveyor belt can be further tightened by adjusting the position of the auxiliary roller 111. If necessary, the axis of the auxiliary roller 111 can be set to be slightly inclined, and the running position of the belt body can be corrected by making it deviate from the parallelism with the axis of the main roller 112 to prevent it from running off.

[0036] The above description is only a preferred embodiment of the utility model, and does not limit the technical scope of the utility model. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
