Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic processing technology, and in particular to a glue-applying processing mechanism for photovoltaic modules used in photovoltaic processing production lines. Background Technology
[0002] As national environmental protection requirements become increasingly stringent, clean energy is playing an increasingly important role, with rapid development in fields such as wind power and solar power. Solar power, in particular, has received significant attention from the power generation industry due to its inexhaustible energy source. Besides solar energy itself, the most crucial element in the solar power industry is photovoltaic (PV) modules. These modules require frames, which need to be glued to before installation. Current technology typically uses a glue applicator head that penetrates deep into the grooves of the frame to apply the glue. However, since frames are generally long, if the glue dispensing rate is low, uneven glue distribution can easily occur, resulting in inconsistent sealant content across the frame's application area. Conversely, if the glue dispensing rate is high, glue overflow can easily occur. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a glue application mechanism for photovoltaic modules. This glue application mechanism can effectively prevent glue from overflowing into the strip groove, and can improve the uniformity and consistency of glue application as well as the bonding stability with external components.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a photovoltaic module adhesive application mechanism, comprising: a bracket, a dispensing valve, and a dispensing nozzle connected at one end to the dispensing outlet of the dispensing valve. A strip-shaped groove extending along its length is formed on the photovoltaic module, with one side wall of the groove being higher than the other. The other end of the dispensing nozzle is used to dispense adhesive into the strip-shaped groove. An X-axis driving mechanism is mounted on the bracket, and a Z-axis driving mechanism is mounted on the movable part of the X-axis driving mechanism, which is movable along the X-axis. A support base is connected to the movable part of the Z-axis driving mechanism, and a dispensing nozzle extending along the Z-axis... A drive shaft is rotatably mounted on the support base. One end of the drive shaft is connected to a motor mounted on the support base. The dispensing valve is mounted on the other end of the drive shaft via a connecting bracket. The dispensing nozzle includes a body extending along the Z-axis and a sleeve connected to the dispensing port of the dispensing valve. A dispensing channel communicating with the sleeve is formed inside the body. The end face of the body away from the sleeve is set as an inclined surface. When the end of the body away from the sleeve of the dispensing nozzle is embedded in the strip groove on the photovoltaic module, the end face of the body away from the sleeve faces the side wall of the higher side of the strip groove.
[0005] The following are further improvements to the above technical solution: 1. In the above scheme, the drive shaft passes through the support seat and rotates with the support seat through at least two spaced bearings.
[0006] 2. In the above scheme, a speed reducer is provided between the motor and the drive shaft, and the drive shaft is connected to the output shaft of the speed reducer.
[0007] 3. In the above scheme, the length of the photovoltaic module is greater than 1 meter.
[0008] 4. In the above scheme, a first Y-axis drive mechanism and a second Y-axis drive mechanism are respectively installed on the bracket, and the two ends of the X-axis drive mechanism are respectively connected to the movable parts of the first Y-axis drive mechanism and the second Y-axis drive mechanism, which can move synchronously along the Y-axis.
[0009] 5. In the above scheme, the cross-section of the glue outlet channel is set to be strip-shaped.
[0010] 6. 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°.
[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model discloses a glue-applying mechanism for photovoltaic modules. The photovoltaic module has a strip-shaped groove extending along its length. One side wall of the groove is higher than the other. The other end of a dispensing nozzle is used to dispense glue into the groove. An X-axis drive mechanism is mounted on a support. A Z-axis drive mechanism is mounted on the movable part of the X-axis drive mechanism, which is movable along the X-axis. A support base is connected to the movable part of the Z-axis drive mechanism. A drive shaft extending along the Z-axis is rotatably mounted on the support base. One end of the drive shaft is connected to a motor mounted on the support base. A dispensing valve is mounted on the other end of the drive shaft via a connecting bracket. The dispensing nozzle includes a body extending along the Z-axis and a glue outlet connected to the dispensing valve. The connected sleeve part has a glue dispensing channel inside the main body that communicates with the sleeve part. The end face of the main body part away from the sleeve part is set as an inclined surface. When the end of the dispensing nozzle part away from the sleeve part is embedded in the strip groove on the photovoltaic module, the end face of the main body part away from the sleeve part faces the side wall of the higher side of the strip groove. Through the cooperation between the glue dispensing inclined surface on the dispensing nozzle that can rotate with the motor and the side wall of the higher side of the strip groove of the photovoltaic module, it can effectively prevent glue from overflowing into the strip groove, and can also naturally spread the glue flowing out from the inclined surface 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.

[0014] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.
[0015] Example 1: A photovoltaic module adhesive application mechanism includes: a bracket 1, a dispensing valve 2, and a dispensing nozzle 3 connected at one end to the dispensing port of the dispensing valve 2.

When the end of the body portion 31 of the dispensing nozzle 3 away from the sleeve portion 32 is embedded in the strip groove 101 on the photovoltaic module 100, the end face of the body portion 31 away from the sleeve portion 32 faces the side wall of the higher side of the strip groove 101.
[0016] The aforementioned drive shaft 10 passes through the support base 9 and is rotatably engaged with the support base 9 through at least two spaced bearings 7; a reducer 8 is provided between the aforementioned motor 11 and the drive shaft 10, and the drive shaft 10 is connected to the output shaft of the reducer 8.
[0017] The cross-section of the aforementioned glue outlet channel 33 is set to be strip-shaped; the angle between the end face of the aforementioned body part 31 away from the sleeve part 32 and the Z-axis direction is 30°.
[0018] Example 2: A photovoltaic module adhesive application mechanism includes: a bracket 1, a dispensing valve 2, and a dispensing nozzle 3 connected at one end to the dispensing port of the dispensing valve 2. The photovoltaic module 100 has a strip-shaped groove 101 extending along its length. One side wall of the strip-shaped groove 101 is higher than the other side. The other end of the dispensing nozzle 3 is used to dispense adhesive into the strip-shaped groove 101. An X-axis drive mechanism 4 is mounted on the bracket 1. A Z-axis drive mechanism 6 is mounted on the movable part of the X-axis drive mechanism 4, which is movable along the X-axis. A support base 9 is connected to the movable part of the Z-axis drive mechanism 6. A drive shaft 10 extending along the Z-axis is rotatably mounted on the support base 9. One end of the drive shaft 10 is connected to the motor 11 mounted on the support base 9. The dispensing valve 2 is mounted on the other end of the drive shaft 10 via a connecting bracket 12. The dispensing nozzle 3 includes a body portion 31 extending along the Z-axis and a sleeve portion 32 connected to the dispensing port of the dispensing valve 2. A dispensing channel 33 communicating with the sleeve portion 32 is provided in the body portion 31. The end face of the body portion 31 away from the sleeve portion 32 is set as an inclined surface. When the end of the body portion 31 of the dispensing nozzle 3 away from the sleeve portion 32 is embedded in the strip groove 101 on the photovoltaic module 100, the end face of the body portion 31 away from the sleeve portion 32 faces the side wall of the higher side of the strip groove 101.
[0019] The length of the photovoltaic module 100 is greater than 1 meter; the bracket 1 is respectively equipped with a first Y-direction drive mechanism 51 and a second Y-direction drive mechanism 52, and the two ends of the X-direction drive mechanism 4 are respectively connected to the movable parts of the first Y-direction drive mechanism 51 and the second Y-direction drive mechanism 52 which can move synchronously along the Y direction.
[0020] The cross-section of the aforementioned glue outlet channel 33 is set to be strip-shaped; the angle between the end face of the aforementioned body part 31 away from the sleeve part 32 and the Z-axis direction is 50°.
[0021] In use, at least one photovoltaic module is mounted on an external clamping and positioning mechanism, such that the strip groove to be dispensed on it extends along the X direction and is located below the dispensing nozzle. The external clamping and positioning mechanism is within the scope of existing technology and can be purchased externally. The applicant also has prior related applications, which will not be elaborated here. 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 photovoltaic module; Next, the motor drives the drive shaft to rotate the dispensing valve with the dispensing nozzle installed, so that the inclined surface of the dispensing nozzle away from the dispensing valve faces the side wall of the higher side of the strip groove. Then, the end of the dispensing nozzle furthest from the dispensing valve is embedded into the strip groove by the Z-axis drive mechanism, and the distance between the dispensing nozzle and the strip groove on the photovoltaic module is optimal. 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 photovoltaic module. During this process, the adhesive flowing out from the inclined surface of the dispensing 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 components to be bonded (such as photovoltaic glass) are subsequently embedded into the strip groove coated with adhesive, the bonding stability between them and the photovoltaic module can be improved. After dispensing adhesive to one photovoltaic module, 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 strip groove on the next photovoltaic module. The above steps can be repeated to achieve the dispensing operation on another photovoltaic module.
[0022] The aforementioned adhesive dispensing mechanism for photovoltaic modules utilizes a dispensing nozzle that rotates with a motor. The inclined surface of the dispensing nozzle, which rotates with the motor, engages with the sidewall of the higher side of the strip groove in the photovoltaic module. This effectively prevents adhesive from overflowing from the strip groove and allows the adhesive flowing from the inclined surface of the dispensing channel to spread naturally and form a uniformly and continuously distributed adhesive layer within the strip groove. This improves the uniformity and consistency of the dispensing process and the bonding stability with external components.
[0023] 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.
