Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module testing technology, and in particular relates to an avoidance limiting component for a hot spot detection machine. Background Technology

[0002] In the photovoltaic (PV) module manufacturing process, hot spot detection is an essential step in the PV module production line. Hot spots occur when certain cells get hotter than other parts during operation, which can be caused by localized shading, cracks, poor welding, or other manufacturing defects. Prolonged hot spots can lead to power loss and even damage the entire PV module. Therefore, quality control and fault diagnosis of PV modules are crucial.

[0003] Specialized hot spot detection machines are required for hot spot detection. Most existing hot spot detection machines are equipped with a conveying assembly to transport photovoltaic modules. The conveying assembly is equipped with limit components to limit the photovoltaic modules after they arrive at their destination. Existing limit components include limit sensors set on the conveying path of the conveying assembly. When transporting larger photovoltaic modules, both sides of the photovoltaic modules will come into contact with the limit sensors. After long-term use, the limit sensors may be damaged, affecting the service life of the limit components, which urgently needs to be solved. Utility Model Content

The transmitting unit is configured to transmit an initial signal to the receiving unit from bottom to top through the gap between the two conveyor belts. The receiving unit is configured to transmit a stop signal to the conveying mechanism when the photovoltaic module on the two conveyor belts blocks the gap between the two conveyor belts located directly above the transmitting unit, thereby limiting the movement of the photovoltaic module.

[0008] Furthermore, the launching unit is vertically and flexibly positioned below the testing station via a lifting assembly.

[0009] Furthermore, the lifting assembly includes a lifting drive and a lifting component. The lifting component is movably disposed below the detection station. The transmitter is mounted on the lifting component. The driving end of the lifting drive is connected to the lifting component. The lifting drive is configured to drive the lifting component to move up and down, thereby moving the transmitter closer to or away from the receiver.

[0010] Furthermore, the gap between the two conveyor belts is between 5mm and 15mm.

[0011] Furthermore, the gap between the two conveyor belts is 10mm.

[0012] Furthermore, the conveying mechanism also includes a base, a driving wheel, a driven wheel, and a rotary drive component, wherein:

[0016] Furthermore, the adsorption assembly includes a plurality of Bernoulli suction cups based on the Bernoulli effect, which are spaced apart along the length of the blocking member.

[0017] Compared with the prior art, the beneficial effects of the aforementioned obstacle avoidance limiting component for hot spot detection machine are as follows:

[0018] 1) The obstacle avoidance limiting component composed of the transmitter and receiver works in conjunction with the conveyor mechanism to limit the movement of the photovoltaic module by utilizing the gap of the conveyor belt and the shading of the photovoltaic module. This can accurately control the position of the photovoltaic module at the inspection station, ensure that the inspection mechanism can accurately detect hot spots on the photovoltaic module, improve the accuracy and reliability of the inspection, and will not affect the normal operation of the transmitter and the conveyor mechanism, thus extending the service life of the transmitter.

[0027] Please see Figures 1 to 3 As shown, this embodiment provides an obstacle avoidance limiting component for a hot spot detection machine. The hot spot detection machine includes a conveying mechanism 10 and a detection mechanism 20. The conveying mechanism 10 has a loading station 11 and a detection station 12 along its conveying path. The detection station 12 is located directly above the photovoltaic module 30 located at the detection station 12. The obstacle avoidance limiting component for the hot spot detection machine includes a transmitter 40 and a receiver 50. The conveying mechanism 10 includes two parallel and spaced conveyor belts 13. The two conveyor belts 13 jointly carry the photovoltaic module 30 at the loading station 11 and load the jointly carried photovoltaic module 30. The photovoltaic module 30 is conveyed to the inspection station 12; the transmitter 40 is vertically and vertically arranged below the inspection station 12 with the transmitting end of the transmitter 40 facing upwards, and the receiver 50 is arranged on the inspection mechanism 20 with the receiving end of the receiver 50 facing downwards. The receiver 50 is electrically connected to the conveyor belt 13. The transmitter 40 is configured to transmit an initial signal to the receiver 50 from bottom to top through the gap between the two conveyor belts 13. The receiver 50 is configured to stop transmitting a signal to the conveyor mechanism 10 when the photovoltaic module 30 on the two conveyor belts 13 blocks the gap between the two conveyor belts 13 located directly above the transmitter 40, thereby limiting the movement of the photovoltaic module 30.

[0028] As can be seen, the obstacle avoidance limiting component composed of the transmitter 40 and the receiver 50, in cooperation with the conveyor mechanism 10, uses the gap of the conveyor belt 13 and the shading of the photovoltaic module 30 to limit the movement of the photovoltaic module 30. This can accurately control the position of the photovoltaic module 30 at the inspection station 12, ensuring that the inspection mechanism 20 can accurately detect hot spots on the photovoltaic module 30, improving the accuracy and reliability of the inspection, without affecting the normal operation of the transmitter 40 and the conveyor mechanism 10, and extending the service life of the transmitter 40.

[0029] In one embodiment, the launching unit 40 is vertically and vertically positioned below the testing station 12 via the lifting assembly 60.

[0030] As can be seen, the launch unit 40 is set up in a height-adjustable manner through the lifting assembly 60, which makes it easy to adjust the launch unit 40 to a suitable position when the equipment is being maintained, debugged or not in operation, so as to avoid unnecessary collision damage to it. It also makes it easy to inspect and replace the launch unit 40, thereby improving the maintainability and service life of the equipment.

[0031] In one embodiment, the lifting assembly 60 includes a lifting drive 61 and a lifting member 62. The lifting member 62 is movably disposed below the detection station 12. The transmitter 40 is mounted on the lifting member 62. The driving end of the lifting drive 61 is connected to the lifting member 62. The lifting drive 61 is configured to drive the lifting member 62 to move up and down, thereby moving the transmitter 40 closer to or away from the receiver 50.

[0032] In one implementation, the gap between the two conveyor belts 13 is between 5mm and 15mm.

[0033] In one implementation, the gap between the two conveyor belts 13 is 10 mm.

[0034] In one embodiment, the conveying mechanism 10 further includes a base 14, a drive wheel 15, a driven wheel 16, and a rotary drive member 17, wherein: the drive wheel 15 is rotatably mounted on a first end of the base 14, the driven wheel 16 is rotatably mounted on a second end of the base 14, and the conveyor belt 13 is sleeved on the drive wheel 15 and the driven wheel 16; the fixed end of the rotary drive member 17 is mounted on the base 14, the driving end of the rotary drive member 17 is connected to the drive wheel 15, and the rotary drive member 17 is configured to drive the drive wheel 15 to rotate, so as to drive the conveyor belt 13 to rotate through the driven wheel 16.

[0035] In one embodiment, a blocking member 18 is fixedly provided on the base 14 along its own length direction, and an adsorption component is provided on the blocking member 18. The adsorption component is configured to adsorb the two sides of the photovoltaic module 30 during transportation.

[0036] In one embodiment, the adsorption assembly includes a plurality of Bernoulli suction cups 180 based on the Bernoulli effect, which are spaced apart along the length of the blocking member 18.

[0037] It is evident that using a suction cup based on the Bernoulli effect as an adsorption component has the characteristics of non-contact adsorption, which will not cause scratches or other damage to the surface of the photovoltaic module 30. While ensuring stable adsorption, it protects the appearance quality of the photovoltaic module 30. Moreover, this suction cup has a simple structure and stable suction force, which helps to improve the reliability and service life of the equipment and reduce maintenance costs.

[0038] When the aforementioned obstacle avoidance limiting component for the hot spot detection machine is in operation: the photovoltaic module 30 is placed at the loading station 11 of the conveying mechanism 10, the rotary drive 17 drives the drive wheel 15 to rotate and, together with the driven wheel 16, drives the two conveyor belts 13 to rotate, conveying the photovoltaic module 30 located at the loading station 11 toward the detection station 12. When it has not reached the preset position, the transmitter 40 continuously transmits an initial signal to the receiver 50, the rotary drive 17 drives the two conveyor belts 13 to rotate, when the photovoltaic module 30 on the two conveyor belts 13 blocks the gap between the two conveyor belts 13 located directly above the transmitter 40, the receiver 50 cannot receive the initial signal emitted by the transmitter 40, and then the receiver 50 transmits a stop signal to the conveying mechanism 10, the rotary drive 17 stops working, and thus limits the movement of the photovoltaic module 30. After the limit is completed, the detection mechanism 20 performs hot spot detection on the photovoltaic module 30 that has been conveyed to the position.

[0039] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
