[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0027] As introduced in the background, during the welding process of the photovoltaic junction box, the welding head needs to be pressed down so that the busbar in the junction box and the copper sheet in the junction box are welded together. During the pressing process of the welding head, the pressure of the pressing down is difficult to detect and obtain. If the pressure applied by the welding head on the busbar and the copper sheet is too large, the excessive pressure will cause hidden cracks in the battery cells inside the junction box. If the downward pressure is too small, the welding of the busbar and the copper sheet will not be tight. In order to better solve this technical problem, the researchers proposed a welding head pressure detection device, which can detect the pressure of the welding head, so as to know whether the pressure of the welding head meets the requirements.

[0028] like Figure 1 As stated, Figure 1The welding head pressure detection device in one embodiment of the present application is used to detect the pressure of the welding head of the photovoltaic module junction box welding device, and includes: a mobile platform 100 and a pressure detection module 200, wherein the mobile platform 100 is used to drive the pressure detection module 200 to move to different workstations, so as to perform pressure detection on the welding heads of different workstations, and the pressure detection module 200 is used to detect the pressure of the welding head, so as to determine whether the pressure of the welding head is within the required range.

[0029] Specifically, the pressure detection module 200 is disposed on the mobile platform 100 and can be driven by the mobile platform 100 to move along a first direction or a direction opposite to the first direction, wherein the first direction can refer to Figure 1 In the direction pointed by the arrow a, the pressure detection module 200 is provided with a pressure sensing part 210, which is located below the welding pressure head. When the welding pressure head is pressed against the pressure sensing part 210, the pressure detection module 200 can detect the pressure of the welding pressure head. The pressure sensing part 210 can be arranged on the upper surface of the pressure detection module 200 and corresponds to the welding pressure head. The pressure detection module 200 may include, for example, a tensile gauge, which measures the slight deformation of the material when subjected to force to determine the force applied to it. The tensile gauge may include a gravitational element and a strain measurement sensor, wherein the gravitational element may be equivalent to the pressure sensing part 210 in this embodiment, and the gravitational element is usually made of a metal material, such as steel or aluminum alloy. When subjected to tension, the gravitational element will undergo a slight deformation, that is, strain. The strain measurement sensor is used to measure the deformation of the gravitational element. The strain measurement sensor can adopt a resistance strain gauge, a strain gauge, a piezoresistive sensor, etc. When the gravitational element is deformed, the resistance or voltage inside the material will also change accordingly. In this embodiment, when the welding pressure head is pressed down, the gravity element will be deformed, and the strain measurement sensor on the gravity element will detect the deformation and convert it into a corresponding electrical signal. After processing by the electronic equipment, an accurate tensile force value can be obtained.

[0030] In this embodiment, the pressure detection module 200 can be driven to move in the first direction or the opposite direction of the first direction by the mobile platform 100. When the pressure detection device moves to the bottom of the welding pressure head, the welding pressure head is pressed down and moves to the pressure sensing part 210 of the pressure detection module 200. The pressure when the welding pressure head is pressed down can be obtained through the pressure sensing part 210, so as to know whether the pressure of the welding pressure head meets the requirements. In addition, by driving the pressure detection module 200 to move in the first direction or the opposite direction of the first direction by the mobile platform 100, the accurate positioning of the pressure detection module 200 and the welding pressure head can be achieved.

[0031] In one embodiment, see Figure 2As shown, the mobile platform 100 includes a conveying mechanism 110 and a clamping mechanism 120 . The conveying mechanism 110 can move in a first direction or a direction opposite to the first direction. The clamping mechanism 120 is disposed on the conveying mechanism 110 and is moved by the conveying mechanism 110 . The clamping mechanism 120 clamps the pressure detection module 200 .

[0032] In this embodiment, when the conveying mechanism 110 moves along the first direction or the opposite direction of the first direction, it can drive the clamping mechanism 120 to move, and the pressure detection module 200 is clamped in the clamping mechanism 120. Therefore, when the conveying mechanism 110 moves along the first direction or the opposite direction of the first direction, it can drive the pressure detection module 200 to move, thereby moving the pressure detection module 200 to a different workstation.

[0033] For further information, see Figure 2 As shown, the conveying mechanism 110 includes a slide rail 111 , a slider 112 and a mounting seat 113 . The slide rail 111 extends along a first direction. The slider 112 is slidably mounted on the slide rail 111 . The mounting seat 113 is mounted on the slider 112 . The clamping mechanism 120 is disposed on the mounting seat 113 .

[0034] In this embodiment, the slide rail 111 extends along the first direction, and the slider 112 can move relative to the slider 112 along the first direction or the opposite direction of the first direction. At the same time, the conveying mode of the slide rail 111 and the slider 112 is adopted, and the mounting seat 113 can be conveyed more stably in the conveying mode, thereby ensuring the stability in the pressure detection. The mounting seat 113 is installed in the slider 112, and when the slider 112 moves, it can drive the mounting seat 113 to move, and the clamping mechanism 120 will also be moved synchronously with the mounting seat 113. In addition, a driving element can be provided to drive the slider 112 to move.

[0035] In one embodiment, see Figure 3 As shown, the clamping mechanism 120 includes a first clamping plate 121, a second clamping plate 122 and an adjusting assembly 123 which are arranged relatively to each other. The pressure detection module 200 is arranged between the first clamping plate 121 and the second clamping plate 122. The adjusting assembly 123 is arranged on the first clamping plate 121. The adjusting assembly 123 clamps the pressure detection module 200 when it moves toward the second clamping plate 122.

[0036] In this embodiment, the first clamping plate 121, the second clamping plate 122 and the adjusting assembly 123 in the clamping mechanism 120 can clamp pressure detection modules 200 of different sizes. In this embodiment, the pressure detection module 200 can be placed between the first clamping plate 121 and the second clamping plate 122, and the distance between the adjusting assembly 123 and the second clamping plate 122 is changed, so that the adjusting assembly 123 presses against the pressure detection module 200 during the movement, thereby achieving the purpose of fixing the pressure detection module 200. When it is necessary to install pressure detection modules 200 of different sizes, the distance between the adjusting assembly 123 and the second clamping plate 122 can be changed at this time, so that the clamping mechanism 120 can adapt to pressure detection modules 200 of different sizes. In this embodiment, the adjusting assembly 123 can be a screw, for example, a threaded hole is provided in the first clamping plate 121, and the screw can press against the pressure detection module 200 when it rotates relative to the threaded hole.

[0037] Further, in one embodiment, see Figure 3 As shown, a rubber pad 300 is provided between the adjustment component 123 and the first clamping plate 121. In this embodiment, by providing the rubber pad 300 between the adjustment component 123 and the first clamping plate 121, on the one hand, the adjustment component 123 can be protected from damaging the first clamping plate 121 during the movement; on the other hand, the provided rubber pad 300 can ensure a tight connection between the adjustment component 123 and the first clamping plate 121.

[0038] In one embodiment, see Figure 1 As shown, the conveying mechanism 110 further includes a mounting platform 400 , the slide rail 111 is disposed on the mounting platform 400 , and fasteners 500 are respectively disposed at both ends of the mounting platform 400 .

[0039] In this embodiment, by providing a mounting platform 400 and installing the slide rail 111 in the mounting platform 400, the rail can be installed by fixing the mounting platform 400 in the actual track layout. The mounting platform 400 is positioned at both ends by fasteners 500, thereby fixing the mounting platform 400. The fasteners 500 may be screws.

[0040] In one embodiment, there are multiple welding head pressure detection devices, and the pressure detection module 200 of each welding head pressure detection device is correspondingly located under each welding head.

[0041] In this embodiment, by configuring a welding pressure head pressure detection device for each welding pressure head, pressure detection can be performed for each welding pressure head in parallel, thereby improving the detection efficiency of pressure detection.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
