Description

Technical Field

[0001] The utility model mainly relates to the technical field of temperature measurement of battery wafers, and particularly relates to a temperature measurement device for a screen curing furnace of solar battery wafers. Background Art

[0002] In the production process of photovoltaic battery wafers, the curing furnace heats substances to a certain temperature to trigger chemical or physical reactions, causing the substances to solidify and change in structure. This heating process can be achieved in various ways, including constant temperature heating, temperature control, heat conduction, and radiation, etc., to ensure that the battery wafers are evenly heated and achieve the purpose of curing. The working principle of the curing furnace includes constant temperature heating and temperature control. Heat energy is provided through heating elements (such as electric heaters, burners, etc.) to reach the required temperature inside the furnace. At the same time, a temperature control system is usually installed inside the curing furnace to monitor and adjust the temperature inside the furnace to maintain the stability of the temperature inside the furnace.

[0003] The current curing furnace detection device mainly consists of an inverter + a three-phase high-power motor + a chain pallet, etc. The conveyor belt is a customized stainless steel chain + pallet, and the conveying speed is steplessly adjusted through control software. The furnace temperature wire is connected to the battery wafer for temperature measurement and monitoring. Generally, the battery wafers are loaded through a battery wafer flower basket first, and then a furnace temperature wire of more than ten meters is wrapped with high-temperature tape and connected to the battery wafer to measure and monitor the temperature inside the furnace. Then the flower basket is placed at the feeding place of the curing furnace and enters the heating area of more than ten meters along with the conveyor belt for heating operation.

[0004] The inventor found the following defects during the operation of specific embodiments:

[0005] Since the curing furnace equipment needs to continuously heat the battery wafers, the entire heating area is more than ten meters, and the temperature of multiple battery wafers needs to be measured and monitored each time, resulting in the need to connect multiple long furnace temperature wires to the battery wafers for measurement. During the conveying process of the conveyor belt, the entire conveyor belt is more than ten meters, so the furnace temperature wires are prone to entanglement and breakage, thereby causing the temperature measurement and monitoring to fail.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0031] Refer to the attached Figures 1-5, A temperature measuring device for a screen curing furnace of a solar cell, including a double-position flower basket 1. One side of the double-position flower basket 1 is detachably connected to a furnace temperature instrument, and the other side of the double-position flower basket 1 is detachably connected to a solar cell 2. An insulating box 3 is arranged outside the furnace temperature instrument. The furnace temperature instrument is connected to the solar cell 2 through a high-temperature thermocouple wire 4. When the device works, the solar cell 2 is inserted into one side of the double-position flower basket 1, and then the insulating box 3 loaded with the furnace temperature instrument is placed on the other side of the double-position flower basket 1. Finally, the thermocouple wire 4 of the furnace temperature instrument is pasted to the solar cell 2 through a high-temperature tape. In this way, the furnace temperature instrument can detect the temperature of the solar cell 2 in real time. Subsequently, the entire double-position flower basket 1 is placed on the conveyor belt of the curing furnace for curing operation. The thermocouple wire 4 and the solar cell 2 of this device are both placed on the double-position flower basket 1 and move with the instrument. Therefore, even if the double-position flower basket 1 is continuously put in for curing operation of the solar cell, there will be no situation of wire jamming or winding. After the curing is completed, the double-position flower basket 1 is taken out, and then the solar cell 2 and the furnace temperature instrument are taken out. The temperature curve in the furnace temperature instrument is read through a data reading device, so as to more accurately explore the temperature window in the on-site production process, and then set a more effective process formula.

[0032] The double-position flower basket 1 includes a fixed plate 11 arranged up and down. Between the fixed plates 11, 2 groups of clamping plates 12 are symmetrically arranged. A solar cell clamping plate 13 is arranged inside the clamping plate 12. The solar cell clamping plate 13 on one side is connected to the insulating box 3 through a fixing mechanism 14, and the solar cell clamping plate 13 on the other side is inserted with the solar cell 2. The rear end of the fixed plate 11 is detachably connected to a rear baffle 15. The 2 groups of clamping plates 12 are divided into two loading stations. A fixing mechanism 14 is installed in one loading station. Subsequently, the furnace temperature instrument sleeved with the insulating box 3 is detachably connected to the fixing mechanism 14, and the solar cell 2 to be temperature-measured and cured is inserted into the other station. Then, it is connected through the thermocouple wire 4. The rear baffle 15 can play a blocking role for the fixing mechanism 14 and the inserted solar cell 2 to prevent the two devices from disengaging from the rear end.

[0033] The fixing mechanism 14 includes concave blocks 141 arranged symmetrically. A locking threaded hole 142 is arranged on the side of the concave block 141. The top of the concave block 141 is connected to an L-shaped support plate 143 through a thread. 2 groups of limiting devices 144 are symmetrically arranged on the top of the L-shaped support plate 143. The limiting device 144 is connected to the insulating box 3. The concave block 141 is clamped on the side clamping plate 12 and locked and fixed at an appropriate height through a screw with the locking threaded hole 142. Subsequently, the L-shaped support plate 143 is inserted into the top of the concave block 141 and connected to the card slot of the solar cell 2 clamping plate. The L-shaped support plate 143 is connected to the bottom concave block 141 through a screw, and the installation of the L-shaped support plate 143 can be completed. Finally, the insulating box 3 is connected to the limiting device 144 to complete the fixation of the furnace temperature instrument, which is convenient for subsequent temperature measurement operations.

[0034] The limiting device 144 includes two groups of concave support columns 145 symmetrically arranged. The concave support columns 145 are arranged at the bottom of the L-shaped support plate 143.

Symmetrically arranged connecting plates are provided on both sides of the bottom of the heat insulation box 3. When installing the furnace temperature instrument, first place the furnace temperature instrument into the heat insulation box 3, then place the heat insulation box 3 on the top of the L-shaped support plate 143, rotate the clamping strip 148 so that its direction faces outward. After the heat insulation box 3 is placed in the preset position, pull up the L-shaped support plate 143 and rotate it inward, and then release the L-shaped support plate 143. Under the action of the spring 146, the L-shaped support plate 143 plays a limiting role on the connecting plate of the heat insulation box 3, preventing the heat insulation box 3 from falling during the movement of the entire double-position flower basket 1.

[0035] An anti-slip mechanism is provided on one side of the fixing plate 11. The anti-slip mechanism includes a support block 111 provided on the lower fixing plate 11. A concave clamping groove is formed at the top of the support block 111. An insertion block 112 is provided on the upper fixing plate 11 at the top. An insertion groove is formed in the insertion block 112. A limiting baffle 113 is inserted into the insertion groove. Multiple furnace temperature instruments can be loaded in the heat insulation box 3 of this device. Therefore, multiple thermocouple wires 4 can extend from the heat insulation box 3. The battery cell 2 clamping plates on the other side can be inserted with corresponding numbers of battery cells 2 for temperature detection operations. To prevent the inserted battery cells 2 from sliding out of the battery cell 2 clamping plates, after the battery cells 2 are inserted, the limiting baffle 113 can be inserted into the concave clamping groove at the bottom through the insertion groove.

[0036] The above embodiments merely represent certain implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
