Description

Technical Field

[0001] The utility model relates to the technical field of solar panel production, in particular to a limiting mechanism for solar panel production. Background Art

[0002] Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electrical energy through the photovoltaic effect. They are made up of multiple layers of different materials, each of which has a specific function in the energy conversion process. The manufacturing of solar panels involves a multi-step process that ultimately transforms the raw materials into functional solar panels that can harness the sun's energy. Testing and quality assurance are the final steps in the solar panel manufacturing process, ensuring that the panels produced meet the required performance, reliability and safety standards. This stage involves a series of comprehensive tests and inspections to evaluate the functionality, efficiency and durability of the panels before they are released for installation and use. During the testing process, it is usually necessary to use corresponding limit structures to limit and fix the solar panels to facilitate the testing work.

[0003] During testing, solar panels are usually placed flat on a test bench or clamped and fixed using a simple clamp. Although solar panels have a packaging frame, if the clamping force is too large during the limiting process, it may still cause damage to the internal structure of the solar panel or directly cause deformation of the frame. The existing limiting mechanism used in solar panel production lacks buffering and alarm measures when the force is too large, making it difficult to control the clamping force during use. The solar panel may slide due to being too loose or be damaged due to being too tight. Therefore, a limiting mechanism for solar panel production is proposed to address the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a limiting mechanism for solar panel production, which drives the movable clamp to move through a driving mechanism, thereby changing the distance between the fixed clamp and the movable clamp to play a role of clamping and limiting. Since the structure in the movable clamp that contacts the solar panel is a movable abutment plate, it can overcome the thrust of the buffer spring and retract when the extrusion force reaches a certain level, thereby playing a role of buffering protection. In particular, when the extrusion force is too large and causes the movable abutment plate to retract too much, the alarm mechanism can play an alarm role to remind the operator to stop pressurizing immediately, thereby solving the technical problem that the limiting mechanism used for solar panel production in the prior art lacks buffering and alarm measures when the force is too large, making it difficult to grasp the clamping force during use, and easily resulting in the solar panel sliding due to being too loose or being damaged due to being too tight.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A limiting mechanism for solar panel production, comprising a placing plate, a fixed clamp, a movable clamp and a driving mechanism, wherein the placing plate is provided with two through slide grooves, two fixed clamps are provided and symmetrically fixedly arranged at the bottom of the upper end surface of the placing plate, and slidably arranged in the slide grooves, and the driving mechanism is arranged at the lower end surface of the placing plate and fixedly connected to the bottom of the movable clamp;

At this time, the button battery powers the lamp bead to make it light up, which can serve as a reminder to the operator to avoid damage to the solar panel due to excessive clamping force.

[0011] In a possible implementation, the rear end face of the rear sleeve is fixedly connected to an end semi-cylinder, a sponge pad is fixedly arranged in the groove of the end semi-cylinder, the static contact piece is attached to the front end face of the sponge pad, the moving contact piece is attached to the rear end face of the sliding rod, and the sliding rod is made of insulating material.

[0023] In addition, when the squeezing force is too great and causes the movable plate to shrink too much, the moving contact piece fixed at the tail of the sliding rod will come into contact with the static contact piece, so that the entire alarm circuit is connected. At this time, the button battery powers the lamp bead to make it light up, which can serve as a reminder for the operator to avoid damage to the solar panel due to excessive clamping force, and remind the operator to stop immediately and relieve pressure immediately.

DETAILED DESCRIPTION

[0031] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0032] like Figure 1-3As shown, the present embodiment provides a limiting mechanism for solar panel production, a limiting mechanism for solar panel production, including a placing plate 1, a fixing clamp 2, a movable clamp 3 and a driving mechanism 4, the placing plate 1 is provided with two through slide grooves 11, a total of two fixing clamps 2 are provided and symmetrically fixedly arranged at the bottom of the upper end surface of the placing plate 1, and slidably arranged in the slide grooves 11, and the driving mechanism 4 is arranged at the lower end surface of the placing plate 1 and fixedly connected to the bottom of the movable clamp 3;

[0033] Among them, the main body of the movable clamp 3 is an L-shaped clamp plate 31, a through hole is opened on the L-shaped clamp plate 31 and a sliding rod 32 is slidably arranged therein, a movable abutment plate 33 is fixedly connected to the front end of the sliding rod 32, a buffer spring 34 is arranged between the movable abutment plate 33 and the L-shaped clamp plate 31 and is sleeved on the outside of the sliding rod 32, a rear sleeve 35 is fixedly arranged on the rear end surface of the L-shaped clamp plate 31, the rear end of the sliding rod 32 is slidably arranged in the rear sleeve 35, and an alarm mechanism 36 is arranged on the L-shaped clamp plate 31.

[0034] The movable clamp 3 is driven to move by the driving mechanism 4, thereby changing the distance between the fixed clamp 2 and the movable clamp 3 to play a role of clamping and limiting, and the structure in the movable clamp 3 that contacts the solar panel is the movable abutment plate 33, which can overcome the thrust of the buffer spring 34 and retract when the extrusion force reaches a certain level, thereby playing a role of buffering protection. In particular, when the extrusion force is too large and causes the movable abutment plate 33 to retract too much, the alarm mechanism 36 can serve as an alarm to remind the operator to stop immediately and relieve pressure immediately.

[0035] like Figure 5 As shown, the alarm mechanism 36 includes a detection circuit and a contact piece group, the detection circuit includes a base 361, a button battery 362 and a lamp bead 363 are installed on the base 361, the contact piece group includes a static contact piece 366 and a moving contact piece 367, wherein the button battery 362 and the lamp bead 363 are electrically connected through a wire, the static contact piece 366 and the button battery 362 are electrically connected through a wire, and the moving contact piece 367 and the lamp bead 363 are electrically connected through a wire. When the moving contact piece 367 contacts the static contact piece 366 during movement, the entire circuit will be connected. At this time, the button battery 362 supplies power to the lamp bead 363 to make it emit light, which can serve as a reminder to the operator to avoid damage to the solar panel due to excessive clamping force.

[0036] In addition, the rear end face of the rear sleeve 35 is fixedly connected to the end semi-cylinder 364, and a sponge pad 365 is fixedly arranged in the groove of the end semi-cylinder 364. The static contact piece 366 is attached to the front end face of the sponge pad 365, and the moving contact piece 367 is attached to the rear end face of the sliding rod 32, and the sliding rod 32 is made of insulating material. Through the above-mentioned structural form, the fixed installation of the moving contact piece 367 and the static contact piece 366 is realized, and the moving contact piece 367 can synchronously follow the sliding rod 32 to move forward and backward.

Through the above-mentioned structural form, it is possible to avoid the sliding rod 32 from rotating during the forward and backward sliding process, which causes the movable stop plate 33 to be unable to effectively contact the solar panel.

This structural form can ensure that the connecting plate 43 can move smoothly under the constraint of the guide rod 42 and the guide cylinder 431, thereby enabling the movable clamp 3 fixedly connected to the connecting plate 43 to move smoothly.

[0039] At the same time, a centrally arranged drive motor 44 is fixedly installed on the lower end surface of the supporting plate 1, and a screw rod 45 is fixedly connected to the output shaft end of the drive motor 44. An internal threaded sleeve 46 is fixedly provided in the middle of the connecting plate 43. The screw rod 45 passes through the internal threaded sleeve 46 and is threadedly engaged with the internal threaded sleeve 46. An end fixing plate 47 is fixedly provided on the lower end surface of the supporting plate 1, and the end of the screw rod 45 is rotatably connected to the end fixing plate 47. Through the above-mentioned structural form, the drive motor 44 can be used to drive the screw rod 45 to rotate, and the connecting plate 43 can be driven to move forward and backward under the action of threaded engagement, and finally the movement of the movable clamp 3 is controlled by the drive motor 44.

[0040] like Figure 1 As shown, a rubber pad 21 is attached to the inner wall of the fixing clamp 2, and the surface of the rubber pad 21 is processed to form a plurality of uneven curved lines. Through the above-mentioned structural form, the contact position of the solar panel can be protected, and at the same time, the friction between the fixing clamp 2 and the solar panel can be improved, thereby enhancing the limiting effect.

[0041] The use principle and use process of this utility model:

[0042] The movable clamp 3 is driven to move by the driving mechanism 4, thereby changing the distance between the fixed clamp 2 and the movable clamp 3 to play a role of clamping and limiting, and the structure in the movable clamp 3 that contacts the solar panel is the movable abutment plate 33, which can overcome the thrust of the buffer spring 34 and retract when the squeezing force reaches a certain level, thereby playing a role of buffer protection;

[0043] In addition, when the squeezing force is too great and causes the movable plate 33 to retract too much, the movable contact piece 367 fixed at the tail of the sliding rod 32 will come into contact with the static contact piece 366, so that the entire alarm circuit is connected. At this time, the button battery 362 powers the lamp bead 363 to make it light up, which can serve as a reminder for the operator to avoid damage to the solar panel due to excessive clamping force, and remind the operator to stop immediately and relieve pressure immediately.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
