Description

Technical Field

[0001] This utility model relates to the field of photovoltaic processing technology, and in particular to a frame glue applicator for photovoltaic processing production lines. Background Technology

[0002] Besides solar energy, the most crucial element in the solar power industry is the photovoltaic (PV) module. PV modules require frames, which need to be glued to the frames before installation. Currently, the glue application amount can only be checked manually by random sampling and weighing before and after application. This increases labor costs and makes it impossible to monitor the glue amount on every frame, causing significant inconvenience to the PV module frame gluing process. Therefore, ensuring more accurate silicone sealant application for PV module frames is a pressing technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a frame glue applicator for a photovoltaic processing production line. This frame glue applicator can improve the uniformity and consistency of glue application and the bonding stability between the glue and external components, and can also monitor the glue application amount in real time to ensure the accuracy of glue application.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a frame glue applicator for a photovoltaic processing production line, comprising: a frame, a glue dispensing valve movably mounted on the frame, a glue dispensing nozzle connected at one end to the glue outlet of the glue dispensing valve, and a first substrate and a second substrate spaced apart below the glue dispensing nozzle along the X direction. At least one first weighing sensor and a second weighing sensor are mounted on the upper surface of each of the first substrate and the second substrate. One end of each of the first weighing sensor and the second weighing sensor, which are symmetrically arranged in pairs, is mounted on the first substrate and the second substrate, and the other end of each extends towards the outside of the first substrate and the second substrate and is used to overlap and cooperate with the end of a strip-shaped workpiece extending along the X direction. The strip-shaped workpiece has a strip-shaped groove extending along its length. The other end of the dispensing nozzle is used to dispense glue into the strip-shaped groove. The dispensing valve is movably mounted on the frame via a three-axis drive module. The dispensing nozzle includes a body extending along the Z-axis and a sleeve connected to the glue outlet of the dispensing valve. A glue outlet channel communicating with the sleeve is formed in the body. The end face of the body away from the sleeve is set as an inclined surface.

[0005] The following are further improvements to the above technical solution: 1. In the above scheme, a deformation sensing area is provided between the two ends of the first weighing sensor and the second weighing sensor. The deformation sensing area is located on the outside of the first substrate and the second substrate. A pad is installed on the upper surface of the first weighing sensor and the second weighing sensor at one end close to each other. The upper surface of the pad is used to overlap and contact the lower surface of one end of the strip workpiece.

[0006] 2. In the above scheme, the pad is an elastic pad.

[0007] 3. In the above scheme, the cross-section of the glue outlet channel is set to be strip-shaped.

[0008] 4. In the above scheme, the angle between the end face of the main body part away from the sleeve part and the Z-axis direction is 20°~60°.

[0009] 5. In the above scheme, when the end of the body portion of the dispensing nozzle away from the sleeve portion is embedded in the strip groove on the strip workpiece, the end face of the end portion of the body portion away from the sleeve portion faces the bottom surface of the strip groove and the side wall of one side of it, respectively.

[0010] 6. In the above scheme, the length of the strip-shaped workpiece is greater than 1 meter.

[0011] 7. In the above solution, the three-axis drive module further includes a first Y-axis drive mechanism and a second Y-axis drive mechanism respectively mounted on the frame.

A Z-axis drive mechanism is mounted on the movable part of the X-axis drive mechanism, which can move along the X-axis. The dispensing valve is mounted on the movable part of the Z-axis drive mechanism.

[0012] 8. In the above scheme, the first substrate and the second substrate are respectively mounted on the frame by a support base and located below both ends of the X-axis drive mechanism.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to a frame glue applicator for a photovoltaic processing production line. At least one first weighing sensor and one second weighing sensor are mounted on the upper surfaces of both the first and second substrates. The first and second weighing sensors, symmetrically arranged in pairs, have one end mounted on each substrate, and the other end extending towards each other to the outer side of the substrates to engage with the end of a strip-shaped workpiece extending along the X-direction. The strip-shaped workpiece has a groove extending along its length. The other end of a dispensing nozzle is used to dispense glue into the groove. A dispensing valve is movably mounted on the machine via a three-axis drive module. On the frame, the dispensing nozzle includes a body extending along the Z-axis and a sleeve connected to the dispensing valve outlet. The body has a dispensing channel communicating with the sleeve. The end face of the body away from the sleeve is set as an inclined surface. This allows the adhesive flowing from the inclined surface of the dispensing nozzle to spread naturally and form a uniform and continuous adhesive layer in the groove through the cooperation between the inclined surface of the dispensing nozzle and the groove on the strip workpiece. This improves the uniformity and consistency of dispensing and the bonding stability with external components. It also allows for real-time weighing of the strip workpiece, thereby real-time monitoring of the dispensing amount and ensuring the accuracy of dispensing. Attached Figure Description

One end of each of the first weighing sensor 91 and the second weighing sensor 92, which are symmetrically arranged in pairs, is mounted on the first substrate 7 and the second substrate 8, and the other end of each extends towards the outside of the first substrate 7 and the second substrate 8 and is used to overlap and cooperate with the end of the strip workpiece 100 extending along the X direction. The strip-shaped workpiece 100 has a strip-shaped groove 101 extending along its length direction. The other end of the dispensing nozzle 3 is used to dispense glue into the strip-shaped groove 101. The dispensing valve 2 is movably mounted on the frame 1 via a three-axis drive module. The dispensing nozzle 3 includes a body part 31 extending along the Z-axis direction and a sleeve part 32 connected to the glue outlet of the dispensing valve 2. A glue outlet channel 33 communicating with the sleeve part 32 is provided in the body part 31. The end face of the body part 31 away from the sleeve part 32 is set as an inclined surface.

[0024] A deformation sensing area 93 is provided between each of the two ends of the first weighing sensor 91 and the second weighing sensor 92. The deformation sensing area 93 is located outside the first substrate 7 and the second substrate 8. A pad 10 is installed on the upper surface of the first weighing sensor 91 and the second weighing sensor 92 at one end. The upper surface of the pad 10 is used to overlap and contact the lower surface of one end of the strip workpiece 100.

[0025] The aforementioned pad 10 is a rubber pad; the angle between the end face of the main body 31 away from the sleeve 32 and the Z-axis direction is 50°.

[0026] The length of the strip-shaped workpiece 100 is greater than 1 meter; the three-axis drive module further includes a first Y-axis drive mechanism 51 and a second Y-axis drive mechanism 52 respectively mounted on the frame 1. An X-axis drive mechanism 4 is connected between the movable parts of the first Y-axis drive mechanism 51 and the second Y-axis drive mechanism 52, which can move synchronously along the Y-axis. A Z-axis drive mechanism 6 is mounted on the movable part of the X-axis drive mechanism 4, which can move along the X-axis. The dispensing valve 2 is mounted on the movable part of the Z-axis drive mechanism 6.

[0027] The first substrate 7 and the second substrate 8 are respectively mounted on the frame 1 by a support base and located below both ends of the X-direction drive mechanism 4.

[0028] In use, first transport at least one strip of workpiece to be glued to above two symmetrically arranged load cells, and make the two ends of the strip workpiece overlap and contact the pads on the two load cells. Loosen the strip workpiece so that it is only supported by the pad block; The load cell deforms under pressure from the strip workpiece. By sensing and calculating the deformation, the weight of the strip workpiece is obtained. The load cell is purchased externally, and its working principle is existing technology, so it will not be described in detail here. The strip groove to be dispensed on the strip workpiece, which is mounted between two load cells, extends along the X direction and is located below the dispensing nozzle; Next, the position of the dispensing nozzle in the horizontal direction is adjusted by the first Y-axis drive mechanism, the second Y-axis drive mechanism and the X-axis drive mechanism so that it is located above one end of the strip groove on the strip workpiece. Then, the Z-axis drive mechanism is used to embed the end of the dispensing nozzle away from the dispensing valve into the strip groove, and the distance between the dispensing nozzle and the strip groove on the strip workpiece is optimal. At this time, the inclined surface of the end of the dispensing nozzle away from the dispensing valve faces the inner wall of the strip groove. Finally, the X-axis drive mechanism drives the dispensing nozzle to dispense adhesive along the length of the strip groove, dispensing the adhesive from the dispensing nozzle into the strip groove on the strip workpiece. During this process, the adhesive flowing out from the inclined surface of the adhesive channel naturally spreads out and forms a uniform and continuous adhesive layer in the strip groove, improving the uniformity and consistency of dispensing. Furthermore, when the external component to be bonded (such as photovoltaic glass) is subsequently embedded into the strip groove coated with adhesive, the bonding stability between it and the strip workpiece can be improved. After dispensing glue to one strip workpiece, the first Y-axis drive mechanism and the second Y-axis drive mechanism can simultaneously drive the X-axis drive mechanism to move the dispensing nozzle above one end of the groove on the next strip workpiece. Repeat the above steps to achieve the dispensing operation on another strip workpiece.

[0029] The frame glue applicator used in the photovoltaic processing production line can, through the cooperation between the glue dispensing bevel on the dispensing nozzle and the strip groove on the strip workpiece, naturally spread the glue flowing from the bevel of the glue dispensing channel and form a uniform and continuous glue layer in the strip groove, thereby improving the uniformity and consistency of glue dispensing and the bonding stability with external components. It can also weigh the strip workpiece in real time, thereby monitoring the glue dispensing amount in real time and ensuring the accuracy of glue dispensing.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
