Description

Technical Field

[0001] This utility model relates to the field of photovoltaic processing technology, and in particular to a dispensing mechanism for photovoltaic frames used for applying adhesive in photovoltaic processing production lines. Background Technology

[0002] Photovoltaic modules typically consist of a laminate, a junction box, and a frame, and are commonly used in transportation, communications, petroleum, marine, and meteorological fields. In practical applications, the frame is installed around the laminate, and a sealant is used to fill the space between the frame and the laminate to enhance sealing. In existing technology, a sealant applicator is typically used, with its applicator head inserted deep into the grooves of the frame for sealant application. However, due to the relatively long length of the frame, uneven sealant application from the applicator head is easily achieved, resulting in inconsistent sealant content across the sealant-applied area of ​​the frame, affecting the stability of the connection with the laminate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dispensing mechanism for a photovoltaic frame, which can form a uniformly and continuously distributed adhesive layer, thereby improving the uniformity and consistency of dispensing and the bonding stability with external components.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dispensing mechanism for a photovoltaic frame, 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 frame. 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 bracket via a three-axis drive module. The dispensing nozzle includes a body extending along the Z-axis and a sleeve connected to the dispensing outlet of the dispensing valve. A dispensing 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, the cross-section of the glue outlet channel is set to be strip-shaped.

[0006] 2. 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°.

[0007] 3. 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 photovoltaic frame, 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.

[0008] 4. In the above scheme, the length of the photovoltaic frame is greater than 1 meter.

[0009] 5. 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 bracket. An X-axis drive mechanism is connected between 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. 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.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The present invention relates to a dispensing mechanism for a photovoltaic frame. The photovoltaic frame has a strip-shaped groove extending along its length. The other end of the dispensing nozzle is used to dispense adhesive into the strip-shaped groove. The dispensing valve is movably mounted on a bracket via a three-axis drive module. The dispensing nozzle includes a body extending along the Z-axis and a sleeve connected to the dispensing valve's outlet. The body has an adhesive flow channel communicating with the sleeve.

Detailed Implementation

[0013] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0014] Example 1: A dispensing mechanism for a photovoltaic frame 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 frame 100 has a strip-shaped groove 101 extending along its length direction. The other end of the dispensing nozzle 3 is used to dispense adhesive into the strip-shaped groove 101. The dispensing valve 2 is movably mounted on the bracket 1 via a three-axis drive module. The dispensing nozzle 3 includes a body portion 31 extending along the Z-axis direction and a sleeve portion 32 connected to the dispensing port of the dispensing valve 2. The body portion 31 has a dispensing channel 33 communicating with the sleeve portion 32. The end face of the body portion 31 away from the sleeve portion 32 is set as an inclined surface.

[0015] 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°.

[0016] When the end of the body part 31 of the dispensing nozzle 3 away from the sleeve part 32 is embedded in the strip groove 101 on the photovoltaic frame 100, the end face of the body part 31 away from the sleeve part 32 faces the bottom surface of the strip groove 101 and the side wall of one side of it, respectively.

[0017] Example 2: A dispensing mechanism for a photovoltaic frame, comprising: 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 frame 100 has a strip-shaped groove 101 extending along its length direction. The other end of the dispensing nozzle 3 is used to dispense adhesive into the strip-shaped groove 101. The dispensing valve 2 is movably mounted on the bracket 1 via a three-axis drive module. The dispensing nozzle 3 includes a body portion 31 extending along the Z-axis direction and a sleeve portion 32 connected to the dispensing port of the dispensing valve 2. The body portion 31 has a dispensing channel 33 communicating with the sleeve portion 32. The end face of the body portion 31 away from the sleeve portion 32 is set as an inclined surface.

[0018] The angle between the end face of the main body 31 away from the sleeve 32 and the Z-axis direction is 50°.

[0019] The length of the photovoltaic frame 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 bracket 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.

[0020] In use, at least one photovoltaic frame 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 above one end of the strip groove on the photovoltaic frame. 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 photovoltaic frame 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 photovoltaic frame. 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 frame can be improved. After the glue is applied to one photovoltaic frame, the first Y-axis drive mechanism and the second Y-axis drive mechanism can simultaneously drive the X-axis drive mechanism to move the glue nozzle to the top of one end of the strip groove on the next photovoltaic frame. The above steps can be repeated to apply glue to another photovoltaic frame.

[0021] The dispensing mechanism of the photovoltaic frame described above, through the cooperation between the dispensing bevel on the dispensing nozzle and the strip groove on the photovoltaic frame, can naturally spread the adhesive flowing from the bevel of the dispensing channel and form a uniform and continuous adhesive layer in the strip groove, thereby improving the uniformity and consistency of dispensing and the bonding stability with external components.

They should not be construed as limiting the scope of protection of this utility model.
