Description

Technical Field

[0001] The invention relates to the technical field of topcon batteries, in particular to an anti-crystallization device for an exhaust valve of a topcon battery sheet texturing machine. Background Art

[0002] A texturing machine is required for the production of Topcon battery cells. The silicon wafers and alkaline liquid in the tank of the texturing machine generate gas due to high temperature and chemical reactions. The gas condenses and produces various crystals. The crystals easily gather in the exhaust valve pipe. Because a valve core is provided in the exhaust valve pipe, if the crystals are not cleaned for a long time, it will affect the rotation of the valve core.

[0003] Patent document CN219357255U discloses a topcon battery cell velveting machine with an exhaust valve anti-crystallization device. The protected claim "The utility model can adjust the angle of the nozzle with the cooperation of the adjustment mechanism, so that four groups of nozzles can evenly spray the inner wall of the exhaust valve pipe, thereby improving the effect of cleaning the crystals on the inner wall of the exhaust valve pipe and ensuring that the valve core in the exhaust valve pipe can rotate normally" is disclosed. However, this scheme and other existing technical schemes realize spraying by directly installing a spray structure in the exhaust pipe. However, the spray structure only needs to work when spraying is required to remove crystals. When cleaning is not required, it will obstruct the airflow channel inside the exhaust pipe and increase the exhaust wind resistance. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an anti-crystallization device for the exhaust valve of a TOPCON battery cell texturing machine, which solves the problem that the spray device will obstruct the air flow channel inside the exhaust pipe when not working.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0012] Preferably, a beveled edge block is slidably mounted on the limit rod, a No. 1 spring is sleeved on the limit rod, and a slot for cooperating with the beveled edge block is provided on the limit block.

[0013] Preferably, a No. 2 fixing rod slidably connected to the T-frame is fixedly installed between the support plate and the support ring, and a No. 2 spring is sleeved on the No. 2 fixing rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention uses a starting motor to rotate the screw at its output end, and the rotation of the screw drives the rotating shaft connected to the worm gear to rotate. The rotation of the rotating shaft drives the spray cylinder to rotate 90 degrees to separate the working cylinder from the valve body. The spray cylinder is connected to the valve body. In the non-cleaning state, the working cylinder is above the valve body, and there is no redundant structure inside, which ensures smooth discharge of gas, effectively reduces the resistance in the exhaust process, and improves the operating efficiency of the equipment.

[0017] 3. The present invention sets a plug-in device and starts the electric telescopic rod to move the beveled edge block out of the slot. Under the action of the No. 2 spring, the T-frame drives the cleaning cotton on the arc plate to reset, and the cleaning cotton is moved out of the valve body, so that the reset of the working cylinder and the connection with the valve body are not affected. When cleaning is needed again, the electric telescopic rod drives the beveled edge block out of the T-frame. When the limit block moves upward, the beveled edge block is pushed into the T-frame under the action of the No. 1 spring. When the slot and the beveled edge block are on the same horizontal line, the No. 1 spring resets and pushes the beveled edge block into the slot, so that the limit block is connected to the T-frame, avoiding the situation where the position of the T-frame cannot be determined and the working cylinder cannot be reset and connected to the valve body.

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Embodiment 1

[0026] Reference Figure 1-Figure 4 The present embodiment proposes an anti-crystallization device for the exhaust valve of a topcon battery cell velveting machine. By setting a cleaning device 3, the problem that the spray device will obstruct the air flow channel inside the exhaust pipe when not working is solved. The device includes a valve body 1, a fixed plate 6 is fixedly installed on the valve body 1, a motor 7 is fixedly installed on the fixed plate 6, a worm 8 is fixedly installed on the output end of the motor 7, a rotating shaft 2 is rotatably installed on the valve body 1, a worm wheel 9 for meshing with the worm 8 is fixedly installed on the rotating shaft 2, a working cylinder 22 is fixedly installed on the working cylinder 22, and a spray cylinder 23 is fixedly installed in the spray cylinder 23. A support ring 24 is installed to make the cleaning device 3 rotate more stably. The motor 7 is started to rotate the screw at its output end. The rotation of the screw drives the rotating shaft 2 connected to the worm gear 9 to rotate. The rotation of the rotating shaft 2 drives the spray barrel 23 to rotate 90 degrees so that the working barrel 22 is separated from the valve body 1. The spray barrel 23 is connected to the valve body 1. In the non-cleaning state, the working barrel 22 is above the valve body 1, and there is no redundant structure inside, which ensures smooth discharge of gas, effectively reduces the resistance in the exhaust process, and improves the operation efficiency of the equipment. A cleaning device 3 for cleaning the valve body 1 is installed in the spray barrel 23, and the inside of the valve body 1 can be cleaned by the cleaning device 3;

[0027] The cleaning device 3 includes a support tube 31 fixedly installed in the spray barrel 23 and rotatably connected to the support ring 24, one end of the support tube 31 is fixedly connected to a rotating nozzle 32 connected to the support tube 31, and a curved tube 33 is fixedly installed on the rotating nozzle 32. The curved tube 33 is a structure that is inclined downward in the vertical direction and bent to one side in the horizontal direction. Under the reaction force of the water flow, the curved tube 33 can spin. A water supply pipe 34 connected to the support tube 31 is installed on the spray barrel 23 for connecting to an external water source. A support plate 35 is fixedly installed on the rotating nozzle 32, a T-shaped frame 36 is slidably installed on the support plate 35, a fixed frame 37 is fixedly installed on the T-shaped frame 36, and a fixed frame 37 is fixedly installed on the fixed frame 37. An arc plate 38 is fixedly installed, and cleaning cotton 39 is installed on the arc plate 38. The external water source is transported to the rotating nozzle 32 through the support pipe 31 through the water supply pipe 34. Due to the high water pressure, the curved pipe 33 drives the rotating nozzle 32 to rotate, and the inner wall of the valve body 1 is sprayed and cleaned comprehensively and evenly. Under the action of the connecting device 4, the rotating nozzle 32 rotates and drives the T-frame 36 to move up and down. The movement of the T-frame 36 drives the arc plate 38 connected to the fixed frame 37 to move, so that the cleaning cotton 39 on the arc plate 38 performs secondary cleaning on the inner wall of the valve body 1, effectively removing possible crystals, ensuring the normal operation of the valve core, and extending the service life of the equipment.

[0028] A connecting device 4 is installed on the support plate 35, and the connecting device 4 includes an inner gear ring 41 fixedly installed in the spray barrel 23, a gear 42 meshing with the inner gear ring 41 is rotatably installed in the support plate 35, a support column 43 fixedly connected to the gear 42 is rotatably installed on the support plate 35, and a reciprocating screw rod 44 rotatably connected to the support ring 24 is fixedly installed on the support column 43.

A limit block 46 is provided which is slidably connected to the No. 1 fixed rod 45. The rotating nozzle 32 is driven to rotate through the bent pipe 33. The rotating nozzle 32 drives the gear 42 to rotate. Under the action of the inner gear ring 41, the gear 42 rotates. The rotation of the gear 42 drives the reciprocating screw 44 connected to the support column 43 to rotate in the limit block 46. Under the action of the No. 1 fixed rod 45, the limit block 46 moves up and down on the reciprocating screw 44. Under the action of the plug-in device 5, the limit block 46 can drive the T-shaped frame 36 to move up and down.

[0029] Embodiment 2

[0030] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the shortcoming that the spray device will obstruct the air flow channel inside the exhaust duct when it is not working. Since the position of the T-frame 36 cannot be determined when the valve body 1 is cleaned, if the T-frame 36 and the arc plate 38 are still located in the valve body 1, it will affect the resetting of the working cylinder 22, making the valve body 1 unable to continue working.

[0031] Reference Figure 1-Figure 4The T-shaped frame 36 is provided with a plug-in device 5, which includes an electric telescopic rod 51 fixedly installed in the T-shaped frame 36, a limit plate 52 fixedly installed at the movable end of the electric telescopic rod 51, two symmetrical sets of limit rods 53 fixedly installed on the limit plate 52, a bevel plug block 54 slidably installed on the limit rod 53, a No. 1 spring 55 is sleeved on the limit rod 53, so that the bevel plug block 54 can be quickly reset, and a spring 55 is provided on the limit block 46 for use with the bevel plug block 54 The second fixing rod 57 is fixedly installed between the support plate 35 and the support ring 24 and is slidably connected to the T-shaped frame 36. The second fixing rod 57 is sleeved with a second spring 58, so that the T-shaped frame 36 can be quickly reset. The electric telescopic rod 51 is started so that the limit plate 52 drives the bevel insert block 54 on the limit rod 53 to move into the slot 56 on the limit block 46, so that when the limit block 46 moves downward, the T-shaped frame 36 can be driven to move downward. The second spring 58 is forced to shrink. When the limit block 46 moves downward, the second spring 58 is forced to shrink. When the stop block 46 moves upward, the stop block 46 and the T-shaped frame 36 will not separate under the action of the second spring 58, which is convenient for multiple cleaning. When the valve body 1 is cleaned, the electric telescopic rod 51 is started to move the bevel insert block 54 out of the slot 56. Under the action of the second spring 58, the T-shaped frame 36 drives the cleaning cotton 39 on the arc plate 38 to reset, and the cleaning cotton 39 is moved out of the valve body 1, so that the working cylinder 22 is reset and the connection with the valve body 1 is not affected. When cleaning is needed again The electric telescopic rod 51 drives the beveled edge block 54 to move out of the T-frame 36. When the limit block 46 moves upward, the beveled edge block 54 is pushed into the T-frame 36 under the action of the No. 1 spring 55. When the slot 56 and the beveled edge block 54 are on the same horizontal line, the No. 1 spring 55 is reset to push the beveled edge block 54 into the slot 56, so that the limit block 46 is connected to the T-frame 36, avoiding the situation where the position of the T-frame 36 cannot be determined, resulting in the inability of the working cylinder 22 to be reset and connected to the valve body 1.
