Description

Technical Field

[0001] This utility model relates to the field of photovoltaic processing equipment technology, and in particular to a glue pump pressure plate. Background Technology

[0002] Currently, the photovoltaic industry uses automatic glue applicators to apply glue to photovoltaic frames. Glue applicators have a 100% penetration rate among photovoltaic companies, and their high-precision glue volume control and smooth glue dispensing play an important role in the photovoltaic glue application field.

[0003] The pressure plate is a core component of an automatic glue applicator. Currently, the most common pressure plates used in automatic glue applicators are those that compress the rubber ring (a) to increase the airtightness between the pressure plate (b) and the glue container (e.g., Figure 1 As shown, the current method has the following shortcomings:

[0004] (1) Difficult to clean. The structural adhesive is stable and forcibly cleaning it can easily damage it, resulting in a worse seal.

[0005] (2) It cannot be adapted to plastic buckets of different diameters, and its adaptability is poor;

[0006] (3) Safety cannot be guaranteed. When the pressure plate is lifted, it often brings up the glue bucket, which may hit the employee's foot.

[0007] Based on this, the present invention proposes a glue pump pressure plate to solve the problems mentioned above. Utility Model Content

[0008] The purpose of this invention is to provide a glue pump pressure plate that solves the problems of difficulty in cleaning, poor adaptability, and poor safety of existing structures.

[0009] To solve the above-mentioned technical problems, this utility model provides a glue pump pressure plate, including an inner support plate and an inflatable sealing ring;

[0010] The inflatable sealing ring is installed around the inner support plate;

[0011] The inner support plate is provided with an annular air channel, and the side wall of the inner support plate is provided with multiple air holes at intervals. The air holes connect the annular air channel to the inside of the inflatable sealing ring.

[0012] The inner support plate is provided with an inflation port and an exhaust port that connect to the annular air passage. The inflation port and exhaust port are used for inflating and deflating the inflatable sealing ring, respectively.

[0013] Furthermore, the inner support plate has an adhesive outlet channel in the middle, and the side wall of the adhesive outlet channel is provided with mounting threads.

[0014] Furthermore, the inner side of the inflatable sealing ring is open, and the two ends of the inner side of the inflatable sealing ring are respectively fixed to the two ends of the side wall of the inner support plate.

[0015] Furthermore, the outer wall of the inflatable sealing ring is curved.

[0016] Furthermore, a pressure-sensitive element is provided inside the inflatable sealing ring.

[0017] Furthermore, the exhaust port is connected to a control valve.

[0018] Furthermore, the inflation port is connected to a one-way valve.

[0019] Furthermore, the multiple pores are arranged at uniform intervals.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] (1) The glue pump pressure plate provided by this utility model adopts an inflatable sealing ring instead of the traditional rubber sealing ring. When using it, the inner support plate can be pressed down first and then the inflatable sealing ring can be inflated, which effectively reduces the difficulty of operation.

[0022] (2) When replacing the glue bucket, the pressure plate of the glue pump provided by this utility model can first release the air from the air sealing ring and then take the entire pressure plate out of the glue bucket, which can effectively avoid the risk of the glue bucket being lifted up and falling, causing injury to the feet, thus improving the safety of operation.

[0023] (3) The glue pump pressure plate provided by this utility model can adjust the overall diameter of the glue pump pressure plate and promote the removal of the glue adhering on the inflatable sealing ring by adjusting the inflation degree of the inflatable sealing ring, which effectively improves the adaptability and cleaning difficulty of the glue pump pressure plate.

[0024] (4) Furthermore, by setting annular air channels and multiple air holes evenly spaced on the inner support plate of the pressure plate, the inflation sealing ring maintains good uniformity during inflation and deflation, ensuring good working efficiency and service life of the glue pump pressure plate.

[0029] The glue pump pressure plate of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0030] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0031] like Figure 2 As shown in the figure, this utility model embodiment proposes a glue pump pressure plate, including an inner support plate 1 and an inflatable sealing ring 2; the inflatable sealing ring 2 is annularly installed around the inner support plate 1; the inner support plate 1 is provided with an annular air passage (not shown in the figure), referring to the reference. Figure 3 The inner support disk 1 has multiple air holes 11 spaced apart on its side wall.

[0032] The air hole 11 connects the annular air passage to the interior of the inflatable sealing ring 2; the inner support plate 1 is provided with an air inlet 12 and an air outlet 13 that connect the annular air passage, and the air inlet 12 and the air outlet 13 are used for inflating and deflating the inflatable sealing ring 2, respectively.

[0033] In this embodiment, the inner support plate 1 is connected to the glue pump outlet pipe 3 (e.g., Figure 4 As shown in the diagram, a control valve is installed at the exhaust port 13, and the inflation port is connected to the inflation device via a one-way valve to install the glue pump pressure plate. Before use, the inflation sealing ring 2 is in an uninflated state. During use, the inner support plate 1 is first pressed down. Since the inflation sealing ring 2 is in an uninflated state, the air in the glue bucket will be discharged from the gap between the glue bucket side wall and the inflation sealing ring 2, allowing the glue pump pressure plate to easily enter the glue bucket, reducing the difficulty of operation. After the inner support plate 1 contacts the glue liquid surface in the glue bucket, the inflation device inflates the inflation sealing ring 2 through the inflation port 12. Under the action of the gas, the inflation sealing ring 2 expands and fits against the inner side wall of the glue bucket, achieving a seal between the glue pump pressure plate and the side wall of the glue bucket. The inflation device is then closed. Due to the presence of the one-way valve, the gas inside the inflation sealing ring 2 will not be discharged from the inflation port 12. Then, the inner support plate 1 is pressed down again, and the glue in the glue bucket is discharged from the glue outlet pipe 3, realizing the glue supply of the glue pump.

[0034] After the glue supply is completed, open the control valve connected to the vent 13 to release the gas in the inflatable sealing ring 2. The inflatable sealing ring 2 contracts and separates from the inner wall of the glue barrel. At this time, lift the inner support plate 1. Since the glue barrel and the inflatable sealing ring 2 are in a separated state, the glue barrel will not rise with the inner support plate 1, effectively avoiding the risk of the glue barrel being lifted and falling, which may cause injury to the feet, thus improving the safety of operation.

[0035] Based on the extensibility of the inflatable sealing ring 2, the working diameter of the glue pump pressure plate can be freely adjusted. This allows the glue pump pressure plate to meet the needs of glue buckets of different diameters, making it highly adaptable. Furthermore, after the glue pump pressure plate has finished working, the glue adhering to the inflatable sealing ring 2 can be forced to crack and fall off by shrinking or expanding the inflatable sealing ring 2, effectively reducing the difficulty of cleaning the glue pump pressure plate.

[0036] Furthermore, in this embodiment, due to the arrangement of the annular air passage in the inner support plate 1 and the multiple air holes 11 distributed at the distance between its side walls, the uniformity of inflation and deflation of the inflation sealing ring 2 is effectively improved, thereby ensuring the good working efficiency and service life of the glue pump pressure plate.

[0037] In the above implementation process, the inner support plate 1 has a glue outlet channel 14 in the middle, and the side wall of the glue outlet channel 14 is provided with installation threads, so that the glue outlet tube 3 and the glue pump pressure plate can be detachably installed, which facilitates the maintenance and replacement of the glue pump pressure plate.

[0038] In the above embodiment, the inner side of the inflatable sealing ring 2 is open, and the two ends of the inner side of the inflatable sealing ring 2 are respectively fixed to the two ends of the side wall of the inner support plate 1. The open inner side of the inflatable sealing ring 2 saves material costs and facilitates the installation of the inflatable sealing ring 2.

[0039] In the above embodiments, preferably, the plurality of air holes 11 are evenly spaced to further improve the uniformity of inflation and deflation of the inflation sealing ring 2.

[0040] In one specific embodiment, the outer wall of the inflatable sealing ring 2 is arc-shaped. The arc-shaped structure can form a more uniform elastic contact with the sealing interface, fill in minor surface defects or tolerance deviations, and reduce local gaps that may be caused by planar contact, thereby improving sealing reliability.

[0041] In yet another specific embodiment, a pressure-sensitive element (not shown in the figure) is provided inside the inflatable sealing ring 2.

[0042] Specifically, pressure-sensitive elements (such as diaphragms, bellows, capacitive sensors, etc.) sense changes in gas pressure and convert changes in mechanical deformation or physical parameters (such as capacitance, resistance) into electrical signals (voltage, current, frequency, etc.). These signals are then output to a display terminal or control system via a signal conditioning circuit (amplification, filtering, analog-to-digital conversion). This enables real-time monitoring of the internal air pressure of the inflatable sealing ring 2, allowing for adjustments to the inflation level of the sealing ring 2 based on actual conditions. It also facilitates automatic adjustment of the airtightness between the sealing ring 2 and the rubber barrel as needed. For example, the pressure-sensitive element, the control valve connected to the exhaust port, and the inflation device can be electrically connected to the same control system. The control system uses data collected by the pressure-sensitive element to control the control valve and inflation device to perform relevant actions, thus achieving automatic adjustment of the airtightness between the sealing ring 2 and the rubber barrel.

[0043] It should be noted that the specific details of how the control system controls the operation of the control valve and the inflation device based on the data collected by the pressure-sensitive element are existing technologies and will not be elaborated upon here.

[0044] In summary, the glue pump pressure plate provided by this utility model has at least the following advantages compared with the prior art:

[0045] (1) The glue pump pressure plate provided by this utility model adopts an inflatable sealing ring instead of the traditional rubber sealing ring. When using it, the inner support plate can be pressed down first and then the inflatable sealing ring can be inflated, which effectively reduces the difficulty of operation.

[0046] (2) When replacing the glue bucket, the pressure plate of the glue pump provided by this utility model can first release the air from the air sealing ring and then take the entire pressure plate out of the glue bucket, which can effectively avoid the risk of the glue bucket being lifted up and falling, causing injury to the feet, thus improving the safety of operation.

[0047] (3) The glue pump pressure plate provided by this utility model can adjust the overall diameter of the glue pump pressure plate and promote the removal of the glue adhering on the inflatable sealing ring by adjusting the inflation degree of the inflatable sealing ring, which effectively improves the adaptability and cleaning difficulty of the glue pump pressure plate.

[0048] (4) Furthermore, by setting annular air channels and multiple air holes evenly spaced on the inner support plate of the pressure plate, the inflation sealing ring maintains good uniformity during inflation and deflation, ensuring good working efficiency and service life of the glue pump pressure plate.

[0049] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
