Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0071] like Figure 1-Figure 4 As shown, this embodiment discloses a glue spraying machine, which is used to spray glue and repair glue on the back of a solar panel with a frame installed. The glue spraying machine of this embodiment includes a machine frame 1, a first conveyor 2, a second conveyor 3, a lifting mechanism 4, a blocking clamping mechanism 5, a manipulator 6, a glue gun 7, a detector 8 and a controller (not shown in the figure).

[0072] The machine frame 1 of this embodiment can be a frame structure, which is in the shape of a rectangular parallelepiped as a whole. The first direction of this embodiment is perpendicular to the second direction. For example, the length direction of the machine frame 1 can be the first direction described below, and the width direction of the rectangular parallelepiped can be the second direction described below.

[0073] The first conveyor 2 is installed on the machine frame 1, and the first conveyor 2 transports the product to be glued to move along the first direction.

[0074] The second conveyor 3 is installed on the machine frame 1, and the second conveyor 3 transports the product to be glued to move along a second direction perpendicular to the first direction.

[0075] The lifting mechanism 4 is installed on the machine frame 1 and connected to the second conveyor 3 , and the lifting mechanism 4 drives the second conveyor 3 to move up and down.

[0076] The blocking and clamping mechanism 5 is installed on the machine frame 1, and the blocking and clamping mechanism 5 is used to fix the product to be glued.

[0077] One end of the manipulator 6 is mounted on the machine frame 1. The front end of the manipulator 6 has a long mounting plate. Due to the scanning angle requirement of the detector 8, the glue gun 7 and the detector 8 are respectively mounted on both sides of the long plate, so that the detector 8 is arranged directly opposite the glue application position of the glue gun 7 so as to be able to scan the glue application position.

[0078] The glue gun 7 is installed at the other end of the manipulator 6. The detector 8 is installed at the other end of the manipulator 6, and the detection part of the detector 8 is set directly opposite to the glue application part of the glue gun 7. In this embodiment, the detector 8 can be a 3D laser profile measuring instrument. In addition, in this embodiment, there are two glue guns 7 and two manipulators 6. The two manipulators 6 drive the two glue guns 7 to move symmetrically and synchronously, respectively, and apply glue along a U-shaped route. Setting the U-shaped route can save space for the manipulator.

[0079] The controller is electrically connected or signal-connected with the detector 8 and the manipulator 6 , and the controller determines whether to control the manipulator 6 to continue applying glue according to the detection signal sent by the detector 8 .

[0080] Because the glue gun 7 cannot control the glue amount and can only glue at full power, the glue gun 7 has unstable glue discharge, and due to process requirements, there must be glue overflow on the glue-applying side, so if the detector 8 cannot detect the presence of glue, it means that there is no glue overflow, and the manipulator 6 needs to return here to glue again. In addition, in this embodiment, the first conveyor 2, the second conveyor 3 and the blocking clamping mechanism 5 are also electrically connected or signal-connected to the controller, and the first conveyor 2, the second conveyor 3 and the blocking clamping mechanism 5 are controlled by the controller to work.

[0081] The first conveyor 2 does not interfere with the lifting of the second conveyor 3, thereby ensuring that the lifting mechanism 4 can lift the second conveyor 3 to a height higher than the first conveyor 2. Then the second conveyor 3 transports the product to be glued to the second position along the second direction, the blocking clamping mechanism 5 fixes the product to be glued at the second position, and the manipulator 6 drives the glue gun 7 to glue along the specified route.

[0082] The gluing machine of this embodiment adopts the above-mentioned structural form, which solves the problem that the current gluing machine has no detection of the gluing quality. The detector 8 is used to detect the gluing quality in real time, achieving uniform and complete gluing and reducing the defective rate of products.

[0083] Furthermore, the blocking and clamping mechanism 5 of this embodiment includes a first position-limiting blocking wheel 51 , a second position-limiting blocking wheel 52 and a cylinder clamping mechanism 53 .

[0084] The first limit blocking wheel 51 is installed on the machine frame 1. In the present embodiment, the number of the first limit blocking wheels 51 is eight, which are divided into four groups in pairs, and are symmetrically arranged on both sides of the first conveyor 2 in the second direction, and are distributed in different positions along the first direction, so as to be able to adapt to products to be glued of different sizes. When the first conveyor 2 transports the product to be glued to a predetermined position, the first limit blocking wheel 51 is lifted and the product is stopped at a fixed position. Specifically, the first limit blocking wheel 51 is driven by a cylinder installed on the machine frame 1, and the cylinder is fixed at a predetermined position on the machine frame 1 by a clamp. A rubber roller is installed on the cylinder, and the rubber roller is lifted by the cylinder, and then the side of the rubber roller contacts the product, which plays a role in blocking and avoiding damage to the product.

[0085] The second position limiting blocking wheels 52 are mounted on the machine frame 1. In this embodiment, there are two second position limiting blocking wheels 52. They are symmetrically arranged in pairs on both sides of the second conveyor 3 in the first direction, and the second position limiting blocking wheels 52 are arranged on one side of the first conveyor 2 in the second direction.

[0086] The cylinder clamping mechanism 53 is mounted on the machine frame 1 and is arranged on the other side of the first conveyor 2 in the second direction. The cylinder clamping mechanism 53 cooperates with the second limit blocking wheel 52 to fix the product to be glued after the second conveyor 3 transports the product to be glued to a predetermined position to prevent it from moving during the glue application process. Specifically, the second limit blocking wheel 52 has the same structure as the first limit blocking wheel 51, but the blocking direction is different. Since the conveying directions of the two sets of conveyors are perpendicular, the two sets of blocking wheel structures are also used for blocking in two directions.

[0087] The blocking and clamping mechanism 5 of this embodiment can adjust its position according to the size of different products to be glued, so as to achieve the positioning of products to be glued of different sizes.

[0088] Further, the cylinder clamping mechanism 53 includes a cylinder 531, a connecting rod 532 and a blocking wheel 533. The cylinder 531 is mounted on the machine frame 1 and the piston rod of the cylinder 531 is arranged parallel to the second direction. The connecting rod 532 is connected to the piston rod and its extension direction is parallel to the first direction. A pair of blocking wheels are arranged at both ends of the connecting rod 532 in the length direction.

[0089] The cylinder 531 can drive the connecting rod 532 and the blocking wheel 533 to move along the second direction to cooperate with the second limit blocking wheel 52 to fix the product to be glued. The cylinder 531 can also drive the connecting rod 532 and the blocking wheel 533 to move against the second direction to loosen the product to be glued, and then send the product to be glued out of the glue machine.

[0090] Furthermore, in this embodiment, both ends of the first conveyor 2 in the first direction extend beyond the machine frame 1 , so that the products to be glued can enter the first conveyor 2 for transportation.

[0091] Specifically, in this embodiment, the first conveyor 2 includes four first supports 21 , a first drive motor 22 , a first transmission mechanism, a first rotating shaft 23 and two first conveyor belts 24 .

[0092] Four first supports 21 are mounted on the machine frame 1 in pairs. The first drive motor 22 is mounted on one of the first supports 21. The first transmission mechanism is connected to the output shaft of the first drive motor 22. One end of the first rotating shaft 23 is connected to the first transmission mechanism, and the other end extends along the second direction and rotatably extends into another opposite first support 21. Two first conveyor belts 24 extend along the first direction respectively and are rotatably sleeved on two opposite first supports 21 respectively, and are both connected to the first rotating shaft 23. The first drive motor 22 drives the two first conveyor belts 24 to rotate synchronously through the first transmission mechanism and the first rotating shaft 23.

[0093] The second conveyor 3 includes a base 31 and a first belt conveyor 32. The bottom of the base 31 is connected to the lifting mechanism 4. The first belt conveyor 32 is installed on the base 31. The first belt conveyor 32 can be set in various forms, and an embodiment is given below:

[0094] The first belt conveyor 32 includes a second support 321, a second drive motor 322, a second transmission mechanism, a second rotating shaft 323, and a second conveyor belt 324. The second support 321 is mounted on the base 31. The second drive motor 322 is mounted on the second support 321. The second transmission mechanism is connected to the output shaft of the second drive motor 322. The second rotating shaft 323 is connected to the second transmission mechanism. The second conveyor belt 324 is mounted on the second support 321 and extends along the second direction, and is connected to the second rotating shaft 323. The second drive motor 322 drives the second conveyor belt 324 to rotate through the second transmission mechanism and the second rotating shaft 323.

[0095] Further, the first belt conveyor 32 also includes a third support 325 and a third conveyor belt 326. The third support 325 is installed on the base 31. The third conveyor belt 326 is installed on the third support 325 and extends along the second direction, and is connected to the second rotating shaft 323. The second driving motor 322 drives the third conveyor belt 326 through the second transmission mechanism and the second rotating shaft 323 to rotate.

[0096] In this embodiment, the second conveyor belt 324 and the third conveyor belt 326 are driven to rotate by the same motor and the same output shaft, thereby ensuring that the two belts rotate synchronously.

[0097] Similarly, the first belt conveyor 32 of this embodiment may further include a fourth support and a fourth conveyor belt, a fifth support and a fifth conveyor belt, and all conveyor belts are driven to rotate by the second drive motor 322 through the second transmission mechanism and the second rotating shaft 323. Those skilled in the art should understand that this embodiment does not limit the number of conveyor belts.

[0098] In this embodiment, the second conveyor 3 further includes a second belt conveyor 33 installed on the base 31 and having the same structure as the first belt conveyor 32, and the second belt conveyor 33 is installed in alignment with the first belt conveyor 32. Moreover, in the projection of the plane formed by the first direction and the second direction, the second belt conveyor is located between the two first conveyor belts. The first conveyor and the second conveyor are designed to be cross-positioned to avoid interference between the two.

[0099] In this embodiment, the above structure can be used to transport products to be glued of various sizes, further improving the applicability of the products. Of course, the second conveyor 3 of this embodiment can also include a larger number of belt conveyors.

[0100] This embodiment also discloses a method for applying glue, which uses a glue applying machine as in this embodiment, and the method comprises the following steps:

[0101] Step 1: The product to be glued enters the glue spraying machine at one end of the first conveyor 2 in the first direction.

[0102] Step 2: Control the first conveyor 2 to transport the product to be glued to the first position along the first direction. That is, the product to be glued is transported to the first position along the first direction by the first conveyor 2, and the corresponding first limit blocking wheel 51 is lifted to stop the product to be glued at the first position.

[0103] Step 3: Control the lifting mechanism 4 to raise the second conveyor 3 to a height higher than the first conveyor 2 to support the products to be glued, and control the second conveyor 3 to transport the products to be glued to the second position along the second direction.

[0104] Step 4: Fix the product to be glued at the second position by controlling the blocking clamping mechanism 5. Specifically, the corresponding second position-limiting blocking wheel 52 in the blocking clamping mechanism 5 is lifted to block the product to be glued, and at the same time, the cylinder clamping mechanism 53 in the blocking clamping mechanism 5 drives the connecting rod 532 and the blocking wheel to move along the second direction through the cylinder 531 to cooperate with the second position-limiting blocking wheel 52 to fix the product to be glued, thereby fixing the product to be glued at the second position.

[0105] Step 5: Control the manipulator 6 to drive the glue gun to glue the product to be glued along a predetermined route. That is, the manipulator 6 is controlled to drive the glue gun 7 to glue along the prescribed route. Specifically, two manipulators 6 are used to move symmetrically and synchronously, and glue is applied along a U-shaped route. If the long side of the product to be glued is glued by one manipulator 6, it will exceed the operating range of the manipulator 6. Therefore, setting two manipulators 6 to glue at the same time can increase the gluing speed. At the same time, setting two manipulators 6 to glue along a U-shaped route means that one long side of the product to be glued requires two manipulators 6 to glue a part, so as to avoid exceeding the operating range of the manipulator 6, thereby saving the setting space of the manipulator. It should be noted that the two manipulators are arranged relative to each other, and glue is applied along the U-shaped route respectively. The openings of the two U-shaped routes are relative to each other, forming the four frames of the combined photovoltaic module. In addition, it should be noted that the U-shape is not a strict U-shape, which is similar to half a rectangle.

[0106] Step 6: Use the detector 8 to detect the glue-applied area in real time and collect glue-applied information; the controller receives the glue-applied information and controls the operation of the manipulator 6 and the glue gun 7 according to the glue-applied information.

[0107] Specifically, step 6 includes:

[0108] The controller receives the gluing information and determines that there is no glue overflow at the glued part of the product to be glued according to the gluing information, then controls the manipulator to return to the glued part, and controls the glue gun to continue to add glue to the glued part. Once it is detected that the gluing effect is poor at any position, the manipulator 6 is controlled to return to the position and continue to add glue until there is no poor gluing effect. Specifically, while gluing, the detector 8 behind the glue gun 7 is used, which is a 3D laser profile measuring instrument in this embodiment, to detect the gluing part in real time. Once it is detected that the gluing effect is poor at any position, the manipulator 6 is controlled to return to the position and continue to add glue until there is no poor gluing effect.

[0109] The method provided by the embodiment of the utility model further includes: releasing the product to be glued by controlling the blocking clamping mechanism 5. That is, after the glue is applied, the cylinder 531 in the blocking clamping mechanism 5 is controlled to drive the connecting rod 532 and the blocking wheel to move in the opposite direction to release the product to be glued.

[0110] The method provided by the embodiment of the utility model further includes: controlling the second conveyor 3 to convey the product to be glued from the second position along the second direction to the outside of the glue machine. That is, by controlling the second limit blocking wheel 52 to descend, the second conveyor 3 conveys the product to be glued from the second position along the second direction to the outside of the glue machine.

[0111] The glue machine and glue method of this embodiment can detect the glue point situation in real time, detect whether there is glue shortage or glue overflow during the glue application process, and promptly deal with the insufficient or excessive glue application, thereby achieving uniform and complete glue application. In addition, the glue machine of this embodiment can achieve the effect of universal application of products to be glued of various sizes, and can also achieve the function of 90-degree change of direction transmission, so as to achieve the effect of flexible glue application through the robot 6.
