[0002] In the production and manufacturing of photovoltaic modules, different glue applicators are usually used to apply glue to the frame and junction box. During the glue application process, the glue supply device that delivers the glue to the glue applicator uses compressed air in the cylinder to send the glue to the supply pipe, and then the glue is output through the glue outlet.

[0003] In existing technologies, adhesive supply mechanisms used for photovoltaic adhesive application often result in unstable adhesive output due to high supply pressure and flow rate, which affects the quality of adhesive application. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-flow-rate pneumatic pressure plate glue supply pump, which can continuously supply glue at a large flow rate to ensure the glue consumption requirements of the photovoltaic production line, and also ensure the stability of the output glue pressure and flow rate.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a high-flow pneumatic pressure plate glue supply pump, comprising: a carrier plate for placing a material cylinder, at least two lifting cylinders vertically mounted on the upper surface of the carrier plate, a movable plate connected between the upper ends of the piston rods of the lifting cylinders, and a pressure plate connected to the movable plate by at least two vertical connecting rods. A vertically arranged cylinder is mounted on the lower surface of the movable plate, a cylinder sleeve is connected to the main body of the cylinder, the pressure plate is located directly below the vertically extending cylinder sleeve, and a vertically extending upper connecting shaft is mounted on the lower end of the piston rod of the cylinder. The lower end of the upper connecting shaft passes through the cylinder sleeve for... The pressure plate, which is sealed to the inner wall of the cylinder, has a glue inlet hole in the center that communicates with the inner cavity of the cylinder sleeve. A glue outlet is provided on the upper side wall of the cylinder sleeve. A sealing ring is provided above the glue outlet and between the inner wall of the cylinder sleeve and the outer wall of the upper connecting shaft. A glue-passing sleeve is sealed to the lower end of the cylinder sleeve. A glue-suction tube is sealed to the lower end of the glue-passing sleeve, which has a sealing plate at the upper end. The lower end of the glue-suction tube is embedded in the glue inlet hole on the pressure plate. The lower end of the upper connecting shaft is connected to a lower connecting shaft through a connecting rod. The lower end of the vertically extending lower connecting shaft passes through the glue-passing sleeve and is equipped with a glue scraper.

[0006] A vertically movable component is located inside the glue-applying sleeve and below the sealing plate. A sealing sleeve is fitted onto the lower connecting shaft. The lower part of the movable component is sealed to the upper end of the glue-absorbing cylinder, thus forming a glue inlet chamber between the glue-applying sleeve, the glue-absorbing cylinder, and the movable component. A movable sleeve is fitted outside the connecting rod. A stop is located above the vertically movable sleeve. The lower outer surface of the movable sleeve is sealed to the inner wall of the cylinder liner, thus ensuring the smooth operation of the movable sleeve. A glue storage chamber is formed between the lower part and the sealing plate of the glue sleeve. The lower part of the connecting rod has a radially outward protrusion. The lower end of the movable sleeve can be sealed with the upper surface of the protrusion, thereby forming a glue outlet chamber between the movable sleeve and the connecting rod. The glue inlet chamber and the glue storage chamber are connected by several glue through holes opened on the sealing plate. A glue outlet hole communicating with the glue outlet chamber is opened on the side wall of the upper part of the movable sleeve. A glue outlet flow channel is formed between the glue outlet hole and the glue outlet on the cylinder liner.

[0007] The following are further improvements to the above technical solution:

[0008] 1. In the above scheme, the stop is located at the lower part of the upper connecting shaft.

[0009] 2. In the above scheme, the upper surface of the protrusion on the connecting rod is a tapered surface with an open lower end, and the lower end of the movable sleeve is provided with an inner chamfered surface that can fit with the tapered surface.

[0010] 3. In the above scheme, a first retaining ring is provided between the glue-applying sleeve and the glue-absorbing cylinder. The upper surface of the first retaining ring is sealed to the lower end face of the glue-applying sleeve by an O-ring, and its lower surface is sealed to the upper end face of the glue-absorbing cylinder by an O-ring. The upper end of the first retaining ring is provided with an inner chamfer, and the inner chamfer surface is in sealed contact with the moving part.

[0011] 4. In the above scheme, a lower nut is threadedly connected to the outer wall of the lower end of the cylinder liner. The lower nut is fitted onto the outside of the glued sleeve and is sealed to the outer wall of the glued sleeve.

[0012] 5. In the above scheme, a round nut is fitted on the outer side of the upper end of the cylinder liner, and a fixing plate is fitted below the round nut that is threaded to the cylinder liner and located on the outer side of the cylinder liner. The lower surface of the round nut overlaps with the upper surface of the fixing plate. The fixing plate is connected to a support plate installed on the lower surface of the cylinder body through at least two vertically arranged positioning pins.

[0013] 6. In the above scheme, the glue outlet is located below the fixing plate.

[0014] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0015] This invention relates to a high-flow pneumatic pressure plate glue supply pump. A glue-passing sleeve is sealed to the lower end of the cylinder liner. A glue-suction cylinder is sealed to the lower end of the glue-passing sleeve, which has a sealing plate at its upper end. The lower end of the glue-suction cylinder is embedded in the glue inlet hole on the pressure plate. A lower connecting shaft is connected to the lower end of an upper connecting shaft via a connecting rod. The lower end of the vertically extending lower connecting shaft passes through the glue-passing sleeve and is fitted with a glue scraper. A movable component that can move vertically is located inside the glue-passing sleeve and below the sealing plate. A sealing sleeve is fitted onto the lower connecting shaft, and the lower part of the movable component can be sealed to the upper end of the glue-suction cylinder, thus forming a glue inlet chamber between the glue-passing sleeve, the glue-suction cylinder, and the movable component. A movable sleeve is fitted outside the connecting rod. A stop is provided above the movable sleeve, which can move vertically. The outer surface of the lower part of the movable sleeve is sealed to the inner wall of the cylinder liner. The connection forms a glue storage chamber between the lower part of the movable sleeve and the sealing plate of the glue-feeding sleeve. The lower part of the connecting rod has a radially outward protrusion. The lower end of the movable sleeve can seal with the upper surface of the protrusion, thereby forming a glue outlet chamber between the movable sleeve and the connecting rod. The glue inlet chamber and the glue storage chamber are connected by several glue-feeding through holes opened on the sealing plate. The upper side wall of the movable sleeve has a glue outlet hole that communicates with the glue outlet chamber. There is a glue flow channel between the glue outlet hole and the glue outlet on the cylinder liner. Through the reciprocating movement of the upper and lower connecting shafts, the glue inlet chamber, glue storage chamber and glue outlet chamber are connected alternately, thereby realizing the continuous external supply of glue at a large flow rate to ensure the glue consumption requirements of the photovoltaic production line. It can also ensure the stability of the output glue pressure and flow rate, thereby ensuring the quality of the final glue dispensing. Attached Figure Description

[0023] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0024] Example 1: A high-flow pneumatic pressure plate glue supply pump, comprising: a carrier plate 200 for placing a material cylinder 100, at least two lifting cylinders 300 vertically mounted on the upper surface of the carrier plate 200, a movable plate 400 connected between the upper ends of the piston rods of the lifting cylinders 300, and a pressure plate 3 connected to the movable plate 400 by at least two vertical connecting rods 500. A vertically arranged cylinder 1 is mounted on the lower surface of the movable plate 400. A cylinder sleeve 2 is connected to the main body 101 of the cylinder 1. The pressure plate 3 is located directly below the vertically extending cylinder sleeve 2. A vertically extending upper connecting shaft 4 is mounted on the lower end of the piston rod 102 of the cylinder 1. The lower end of the upper connecting shaft 4 passes into the cylinder sleeve 2 for connecting with the material cylinder 100. The pressure plate 3, which is sealed to the inner wall, has a glue inlet hole 301 in the center that communicates with the inner cavity of the cylinder sleeve 2. A glue outlet 6 is provided on the upper side wall of the cylinder sleeve 2. A sealing ring 8 is provided above the glue outlet 6 and between the inner wall of the cylinder sleeve 2 and the outer wall of the upper connecting shaft 4. A glue-passing sleeve 17 is sealed to the lower end of the cylinder sleeve 2. A glue-suction cylinder 18 is sealed to the lower end of the glue-passing sleeve 17, which has a sealing plate 171 at the upper end. The lower end of the glue-suction cylinder 18 is embedded in the glue inlet hole 301 on the pressure plate 3. The lower end of the upper connecting shaft 4 is connected to a lower connecting shaft 20 through a connecting rod 19. The lower end of the vertically extending lower connecting shaft 20 passes through the glue-passing sleeve 17 and is equipped with a glue scraper 21.

[0025] The piston rod of the cylinder drives the coaxially arranged upper connecting shaft, connecting rod and lower connecting shaft to reciprocate in the vertical direction at a high frequency;

[0026] A movable component 22, which can move vertically, is provided inside the glue-applying sleeve 17 and below the sealing plate 171. The lower part of the movable component 22, which is sealed to the lower connecting shaft 20, can be sealed to the upper end of the glue-absorbing cylinder 18, thereby forming a glue inlet chamber 121 between the glue-applying sleeve 17, the glue-absorbing cylinder 18, and the movable component 22. A movable sleeve 11 is fitted on the outside of the connecting rod 19. A stop part 41 is provided above the movable sleeve 11, which can move vertically. The lower outer surface of the movable sleeve 11 is sealed to the inner wall of the cylinder liner 2, thereby forming a seal between the lower part of the movable sleeve 11 and the glue-applying sleeve 17. A glue storage chamber 122 is formed between the sealing plates 171 of the 7. The lower part of the connecting rod 19 has a radially outward protrusion 191. The lower end of the movable sleeve 11 can be sealed with the upper surface of the protrusion 191, thereby forming a glue outlet chamber 123 between the movable sleeve 11 and the connecting rod 19. The glue inlet chamber 121 and the glue storage chamber 122 are connected by a plurality of glue passage holes 172 opened on the sealing plate 171. A glue outlet hole 111 communicating with the glue outlet chamber 123 is opened on the upper side wall of the movable sleeve 11. A glue outlet channel 13 is formed between the glue outlet hole 111 and the glue outlet 6 on the cylinder liner 2.

[0027] When the piston rod of the cylinder is in the extended state, the scraper at the lower end of the lower connecting shaft is below the glue level in the glue inlet hole. As the scraper moves upward with the lower connecting shaft, the glue pushed upward by the scraper pushes the moving part upward, causing the seal between the moving part and the glue suction cylinder to fail. The glue enters the glue inlet area through the gap between the moving part and the glue suction cylinder, and then enters the glue storage chamber through the glue passage hole. During this process, the moving sleeve moves upward under the action of the protrusion on the connecting rod and maintains the seal with the protrusion. The volume of the glue storage chamber gradually increases until the piston rod of the cylinder switches to the retracted state.

[0028] The aforementioned stop 41 is located at the lower part of the upper connecting shaft 4.

[0029] The upper surface of the protrusion 191 on the connecting rod 19 is a tapered surface with an open lower end, and the lower end of the movable sleeve 11 is provided with an inner chamfered surface that can fit with the tapered surface.

[0030] A first retaining ring 14 is provided between the glue-applying sleeve 17 and the glue-absorbing cylinder 18. The upper surface of the first retaining ring 14 is sealed to the lower end face of the glue-applying sleeve 17 by an O-ring, and its lower surface is sealed to the upper end face of the glue-absorbing cylinder 18 by an O-ring. The upper end of the first retaining ring 14 is provided with an inner chamfer, and the inner chamfer surface is in sealed contact with the movable part 22.

[0031] A lower nut 15 is threadedly connected to the outer wall of the lower end of the cylinder liner 2. The lower nut 15 is fitted onto the outside of the glued sleeve 17 and is sealed to the outer wall of the glued sleeve 17.

[0032] A round nut 51 is fitted on the outer side of the upper end of the cylinder liner 2. A fixing plate 52 is fitted below the round nut 51, which is threaded to the cylinder liner 2, and located on the outer side of the cylinder liner 2. The lower surface of the round nut 51 overlaps with the upper surface of the fixing plate 52. The fixing plate 52 is connected to the support plate 54 installed on the lower surface of the main body 101 of the cylinder 1 through at least two vertically arranged positioning pins 53.

[0033] The aforementioned glue outlet 6 is located below the fixing plate 52.

[0034] Example 2: A high-flow pneumatic pressure plate glue supply pump, comprising: a carrier plate 200 for placing a material cylinder 100, at least two lifting cylinders 300 vertically mounted on the upper surface of the carrier plate 200, a movable plate 400 connected between the upper ends of the piston rods of the lifting cylinders 300, and a pressure plate 3 connected to the movable plate 400 by at least two vertical connecting rods 500. A vertically arranged cylinder 1 is mounted on the lower surface of the movable plate 400. A cylinder sleeve 2 is connected to the main body 101 of the cylinder 1. The pressure plate 3 is located directly below the vertically extending cylinder sleeve 2. A vertically extending upper connecting shaft 4 is mounted on the lower end of the piston rod 102 of the cylinder 1. The lower end of the upper connecting shaft 4 passes through the cylinder sleeve 2 for connecting with the material cylinder 100. The pressure plate 3, which is sealed to the inner wall, has a glue inlet hole 301 in the center that communicates with the inner cavity of the cylinder sleeve 2. A glue outlet 6 is provided on the upper side wall of the cylinder sleeve 2. A sealing ring 8 is provided above the glue outlet 6 and between the inner wall of the cylinder sleeve 2 and the outer wall of the upper connecting shaft 4. A glue-passing sleeve 17 is sealed to the lower end of the cylinder sleeve 2. A glue-suction cylinder 18 is sealed to the lower end of the glue-passing sleeve 17, which has a sealing plate 171 at the upper end. The lower end of the glue-suction cylinder 18 is embedded in the glue inlet hole 301 on the pressure plate 3. The lower end of the upper connecting shaft 4 is connected to a lower connecting shaft 20 through a connecting rod 19. The lower end of the vertically extending lower connecting shaft 20 passes through the glue-passing sleeve 17 and is equipped with a glue scraper 21.

[0035] When in use, the outer wall and the inner wall of the barrel are sealed together and the pressure plate is pushed to below the liquid level in the barrel, so that the glue inlet hole on the pressure plate is filled with glue.

[0036] A movable component 22, which can move vertically, is provided inside the glue-applying sleeve 17 and below the sealing plate 171. The lower part of the movable component 22, which is sealed to the lower connecting shaft 20, can be sealed to the upper end of the glue-absorbing cylinder 18, thereby forming a glue inlet chamber 121 between the glue-applying sleeve 17, the glue-absorbing cylinder 18, and the movable component 22. A movable sleeve 11 is fitted on the outside of the connecting rod 19. A stop part 41 is provided above the movable sleeve 11, which can move vertically. The lower outer surface of the movable sleeve 11 is sealed to the inner wall of the cylinder liner 2, thereby forming a seal between the lower part of the movable sleeve 11 and the glue-applying sleeve 17. A glue storage chamber 122 is formed between the sealing plates 171 of the 7. The lower part of the connecting rod 19 has a radially outward protrusion 191. The lower end of the movable sleeve 11 can be sealed with the upper surface of the protrusion 191, thereby forming a glue outlet chamber 123 between the movable sleeve 11 and the connecting rod 19. The glue inlet chamber 121 and the glue storage chamber 122 are connected by a plurality of glue passage holes 172 opened on the sealing plate 171. A glue outlet hole 111 communicating with the glue outlet chamber 123 is opened on the upper side wall of the movable sleeve 11. A glue outlet channel 13 is formed between the glue outlet hole 111 and the glue outlet 6 on the cylinder liner 2.

[0037] During the transition of the piston rod from the retracted state to the extended state, the movable sleeve moves downward along with the upper connecting shaft and connecting rod, reducing the volume of the glue storage chamber. The glue in the storage chamber is squeezed and exerts an upward reaction force on the movable sleeve, causing it to move upward. This leads to the failure of the seal between the movable sleeve and the protrusion on the connecting rod. The glue enters the glue outlet area through the gap between the movable sleeve and the protrusion, and then passes through the glue outlet hole and glue outlet channel before being output from the glue outlet on the cylinder liner.

[0038] The aforementioned stop 41 is located at the lower part of the upper connecting shaft 4.

[0039] A lower nut 15 is threadedly connected to the outer wall of the lower end of the cylinder liner 2. The lower nut 15 is fitted onto the outside of the glued sleeve 17 and is sealed to the outer wall of the glued sleeve 17.

[0040] The lower end of the nut 15 has a first flange portion 151 extending radially inward on its inner wall, and the upper end of the adhesive suction tube 18 has a second flange portion 181 extending radially outward on its outer wall. The lower surface of the second flange portion 181 overlaps and contacts the upper surface of the first flange portion 151, and the outer surface of the second flange portion 181 is sealed to the inner wall of the nut 15.

[0041] A connecting sleeve 16 is provided between the lower nut 15 and the pressure plate 3 and outside the glue suction cylinder 18. The lower end of the connecting sleeve 16 is embedded in a flange ring 9 and is sealed to the inner wall of the flange ring 9. The flange ring 9 is connected to the upper surface of the pressure plate 3 by bolts. The inner wall of the connecting sleeve 16 is sealed to the outer wall of the glue suction cylinder 18.

[0042] A sealing gasket 10 is provided between the flange ring 9 and the upper surface of the pressure plate 3.

[0043] The upper part of the above-mentioned glue inlet hole 301 is cylindrical, and the lower part is a funnel shape that opens outward.

[0044] The aforementioned material cylinder 100 is positioned between two lifting cylinders 300.

[0045] The lower surface of the movable plate 400 and the upper surface of the pressure plate 3 are connected by two vertical connecting rods 500 symmetrically arranged on both sides of the cylinder liner 2, so that the pressure plate 3 can move vertically with the movable plate 400.

[0046] The working principle of this invention is as follows:

[0047] When in use, the outer wall and the inner wall of the barrel are sealed together and the pressure plate is pushed to below the liquid level in the barrel, so that the glue inlet hole on the pressure plate is filled with glue.

[0048] The piston rod of the cylinder drives the coaxially arranged upper connecting shaft, connecting rod and lower connecting shaft to reciprocate in the vertical direction at a high frequency;

[0049] When the piston rod of the cylinder is in the extended state, the scraper at the lower end of the lower connecting shaft is below the glue liquid level in the glue inlet hole. As the scraper moves upward with the lower connecting shaft, the glue liquid moving upward with the scraper pushes the moving part upward, causing the seal between the moving part and the glue suction cylinder to fail. The glue liquid enters the glue inlet chamber area through the gap between the moving part and the glue suction cylinder and then enters the glue storage chamber through the glue passage hole. During this process, the moving sleeve moves upward under the action of the protrusion on the connecting rod and maintains the seal between it and the protrusion. The volume of the glue storage chamber gradually increases until the piston rod of the cylinder switches to the retracted state.

[0050] During the transition of the piston rod from the retracted state to the extended state, the movable sleeve moves downward along with the upper connecting shaft and connecting rod, reducing the volume of the glue storage chamber. The glue in the storage chamber is squeezed and exerts an upward reaction force on the movable sleeve, causing it to move upward. This leads to the failure of the seal between the movable sleeve and the protrusion on the connecting rod. The glue enters the glue outlet area through the gap between the movable sleeve and the protrusion, and then passes through the glue outlet hole and glue outlet channel before being output from the glue outlet on the cylinder liner.

[0051] The aforementioned high-flow pneumatic pressure plate glue pump, through the reciprocating movement of the upper and lower connecting shafts, drives the staggered connection between the glue inlet chamber, glue storage chamber and glue outlet chamber, thereby enabling the glue to be continuously supplied out at a large flow rate, ensuring the glue demand on the photovoltaic production line, and also ensuring the stability of the output glue pressure and flow rate, thus ensuring the final glue dispensing quality.

[0052] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
