Description

Technical Field

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

[0002] Photovoltaic modules are fitted with frames around their perimeter. Before installation, the frames need to be glued into grooves using a glue applicator. In existing technology, the air pressure of the glue applicator is unstable during the initial glue application, leading to insufficient glue coverage. Typically, the glue amount on the frames is monitored manually by weighing them before and after glue application. However, manual operation involves a large contact area with the workpiece, significantly interfering with the weighing process and potentially causing inaccuracies. Furthermore, the varying placement of the workpiece each time can affect the consistency of the weighing, thus impacting the accuracy of the weighing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a glue quantity measuring mechanism for a dispensing device. This glue quantity measuring mechanism can realize real-time weighing of long strip-shaped workpieces with minimal contact area and interference with the workpiece, and can also improve the weighing accuracy and consistency of weighing each workpiece.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is: a glue volume measuring mechanism for a dispensing device, comprising: a left substrate and a right substrate, wherein a weighing sensor is installed on the upper surface of each of the left substrate and the right substrate, and one end of each of the two symmetrically arranged weighing sensors is installed on the left substrate and the right substrate, and the other end of each extends towards the outside of the left substrate and the right substrate, wherein a deformation sensing area is provided between the two ends of the weighing sensor and the deformation sensing area is located on the outside of the left substrate and the right substrate, and a pad is installed on the upper surface of the end of the weighing sensor located on the outside of the left substrate and the right substrate, wherein the upper surface of each pad is used to overlap and contact the lower surface of one end of the strip workpiece;

[0005] The upper surfaces of the left and right base plates are each equipped with a first movable plate that can move back and forth and a second movable plate that moves in the opposite direction to the first movable plate. A first push block is located near the front end of the pad and connected to the first movable plate. A second push block, which corresponds to the first push block, is installed on the second movable plate and located near the rear end of the pad. This forms a clamping area for embedding a strip workpiece between the corresponding first push block and the second push block. When both the first push block and the second push block are in contact with the strip workpiece located between them, the strip workpiece is located directly above the weighing sensor.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, the first movable plate and the second movable plate are each mounted on the left base plate and the right base plate via slide rails and sliders.

[0008] 2. In the above scheme, the second movable plate is positioned above the first movable plate.

[0009] 3. In the above scheme, the first push block is an L-shaped push block, the vertical part of which is used for pressing and contacting the strip-shaped workpiece, and the horizontal part of which is connected to the first movable plate.

[0010] 4. In the above scheme, the horizontal part of the first push block passes through the weighing sensor above and is connected to the first movable plate, and the upper surface of the horizontal part of the first push block is lower than the upper surface of the pad block.

[0011] 5. In the above scheme, the pad includes a main body connected to the weighing sensor and an extension extending forward and backward from the upper part of the main body, respectively.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] The adhesive quantity measuring mechanism of this utility model dispensing equipment has a weighing sensor mounted on the upper surface of each of its left and right base plates. Two symmetrically arranged weighing sensors have one end mounted on each base plate, and the other end extending towards each other to the outer side of the base plates. A deformation sensing area is provided between the two ends of the weighing sensors, located on the outer side of the base plates. A pad is mounted on the upper surface of the end of the weighing sensor located on the outer side of the base plates. A first movable plate that can move back and forth and a second movable plate that moves in the opposite direction to the first movable plate are also mounted on the upper surface of each base plate. A first pusher block located near the front end of the pad is connected to the first movable plate. Next, a second push block, corresponding to the first push block, is installed on the second movable plate and positioned near the rear end of the pad block, thereby forming a clamping area for embedding the strip workpiece between the corresponding first and second push blocks. When both the first and second push blocks are in pressure contact with the strip workpiece located between them, the strip workpiece is positioned directly above the weighing sensor, enabling real-time weighing of long strip workpieces with minimal contact area and interference, and good weighing accuracy. Furthermore, before weighing, the two sets of push blocks facing each other can be used to clamp and position the two ends of the workpiece, ensuring that the workpiece is positioned directly above the weighing sensor, further improving the weighing accuracy and consistency of weighing each workpiece.

Detailed Implementation

[0019] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0020] Example 1: A glue quantity measuring mechanism for a dispensing device includes: a left substrate 1 and a right substrate 2. A weighing sensor 3 is mounted on the upper surface of each of the left substrate 1 and the right substrate 2. Two symmetrically arranged weighing sensors 3 are mounted at one end on the left substrate 1 and the right substrate 2, and at the other end of each end extend to the outside of the left substrate 1 and the right substrate 2. A deformation sensing area 31 is provided between the two ends of the weighing sensor 3. The deformation sensing area 31 is located on the outside of the left substrate 1 and the right substrate 2. A pad 4 is mounted on the upper surface of the end of the weighing sensor 3 located on the outside of the left substrate 1 and the right substrate 2. The upper surface of each pad 4 is used to overlap and contact the lower surface of one end of a strip workpiece 100.

[0021] The upper surfaces of the left base plate 1 and the right base plate 2 are each equipped with a first movable plate 5 that can move back and forth and a second movable plate 6 that moves in the opposite direction to the first movable plate 5. A first push block 7, which is located near the front end of the pad block 4, is connected to the first movable plate 5. A second push block 8, which is located corresponding to the first push block 7, is installed on the second movable plate 6 and located near the rear end of the pad block 4. Thus, a clamping area for embedding the strip workpiece 100 is formed between the corresponding first push block 7 and second push block 8. When the first push block 7 and the second push block 8 are both in contact with the strip workpiece 100 located between them, the strip workpiece 100 is located directly above the weighing sensor 3.

[0022] The strip workpiece is released so that it is only supported by the pad block. Then, the two corresponding push blocks in each group are driven to move closer to each other until they contact the side surface of the workpiece. This pushes both ends of the workpiece to be directly above the weighing sensor to improve weighing accuracy. After that, the two corresponding push blocks in each group are driven to move away from each other to release the workpiece and avoid interference with the weighing.

[0023] The first movable plate 5 and the second movable plate 6 are each mounted on the left base plate 1 and the right base plate 2 via slide rails and sliders; the second movable plate 6 is positioned above the first movable plate 5.

[0024] The first push block 7 is an L-shaped push block. Its vertical part 71 is used to press against the strip workpiece 100, and its horizontal part 72 is connected to the first movable plate 5. The horizontal part 72 of the first push block 7 passes through the weighing sensor 3 from above and is connected to the first movable plate 5. The upper surface of the horizontal part 72 of the first push block 7 is lower than the upper surface of the pad block 4.

[0025] The aforementioned pad 4 includes a main body 41 connected to the weighing sensor 3 and an extension 42 extending forward and backward from the upper part of the main body 41, respectively; the aforementioned pad 74 is an elastic pad.

[0026] Example 2: A glue quantity measuring mechanism for a dispensing device includes: a left substrate 1 and a right substrate 2. A weighing sensor 3 is mounted on the upper surface of each of the left substrate 1 and the right substrate 2. Two symmetrically arranged weighing sensors 3 are mounted at one end on the left substrate 1 and the right substrate 2, and at the other end of each end extend to the outside of the left substrate 1 and the right substrate 2. A deformation sensing area 31 is provided between the two ends of the weighing sensor 3. The deformation sensing area 31 is located on the outside of the left substrate 1 and the right substrate 2. A pad 4 is mounted on the upper surface of the end of the weighing sensor 3 located on the outside of the left substrate 1 and the right substrate 2. The upper surface of each pad 4 is used to overlap and contact the lower surface of one end of the strip workpiece 100.

[0027] In use, the strip workpiece to be weighed is first transported to the top of two weighing sensors that are symmetrically arranged on the left and right, and the two ends of the strip workpiece are in contact with the pads on the two weighing sensors. At this time, the push blocks of each group of two corresponding push blocks are far apart from each other so as to put the workpiece into the clamping area.

[0028] The upper surfaces of the left base plate 1 and the right base plate 2 are each equipped with a first movable plate 5 that can move back and forth and a second movable plate 6 that moves in the opposite direction to the first movable plate 5. A first push block 7, which is located near the front end of the pad block 4, is connected to the first movable plate 5. A second push block 8, which is located corresponding to the first push block 7, is installed on the second movable plate 6 and located near the rear end of the pad block 4. Thus, a clamping area for embedding the strip workpiece 100 is formed between the corresponding first push block 7 and second push block 8. When the first push block 7 and the second push block 8 are both in contact with the strip workpiece 100 located between them, the strip workpiece 100 is located directly above the weighing sensor 3.

[0029] The load cell deforms under pressure from the strip workpiece. By sensing and calculating the deformation, the weight of the corresponding strip workpiece is obtained. The load cell is purchased externally.

[0030] The first movable plate 5 and the second movable plate 6 are each mounted on the left base plate 1 and the right base plate 2 via slide rails and sliders.

[0031] The first pusher 7 is an L-shaped pusher, with its vertical part 71 used for pressing and contacting the strip-shaped workpiece 100, and its horizontal part 72 connected to the first movable plate 5.

[0032] The aforementioned pad 4 includes a main body 41 connected to the weighing sensor 3 and an extension 42 extending forward and backward from the upper part of the main body 41, respectively; the aforementioned weighing sensor 3 is a parallel beam type sensor.

[0033] The working principle of this utility model is as follows:

[0034] In use, the strip workpiece to be weighed is first transported to the top of two weighing sensors that are symmetrically arranged on the left and right, and the two ends of the strip workpiece are in contact with the pads on the two weighing sensors. At this time, the push blocks of each group of two corresponding push blocks are far apart from each other so as to put the workpiece into the clamping area.

[0035] The strip workpiece is released so that it is only supported by the pad block. Then, the two corresponding push blocks in each group are driven to move closer to each other until they contact the side surface of the workpiece. This pushes both ends of the workpiece to be adjusted to be directly above the load cell to improve the weighing accuracy. After that, the two corresponding push blocks in each group are driven to move away from each other to release the workpiece to avoid interference with the weighing.

[0036] Two cylinders (not shown in the figure) drive the first movable plate and the second movable plate to move in opposite directions, thereby driving the corresponding first push block and second push block to move closer or further apart from each other.

[0037] The load cell deforms under pressure from the strip workpiece. By sensing and calculating the deformation, the weight of the corresponding 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.

[0038] The glue volume measuring mechanism of the above-mentioned dispensing equipment can realize real-time weighing of long strip-shaped workpieces with minimal contact area and interference with the workpiece, and has good weighing accuracy. Before weighing, two sets of push blocks facing each other can clamp and position the two ends of the workpiece, so that the workpiece is directly above the weighing sensor, further improving the weighing accuracy and consistency of weighing each workpiece.

[0039] 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.
