Description

Technical Field

[0001] The utility model relates to the field of feeler gauges, and more specifically, to a feeler gauge for testing the warpage degree of battery wafers. Background Art

[0002] As one of the important raw materials of photovoltaic modules, battery wafers play a very important role in the application of module systems. With the increasing shortage of silicon materials, it is imperative to reduce the cost of silicon wafers and battery wafers. At present, the silicon wafers have reached a thickness of 160 μm, and thinner silicon wafers may be produced in subsequent research. As the silicon wafers gradually become thinner, the battery wafers will also become thinner. However, as the battery wafers become thinner, there will be a problem that the warpage degree of the battery wafers becomes larger. When the warpage of the battery wafers is large, the battery end is likely to cause broken wafers, and the component end is likely to cause false soldering, and hidden cracks are likely to occur, resulting in an increase in cost. Therefore, after the battery wafers are processed, it is necessary to use a feeler gauge to test their warpage degree.

[0003] A feeler gauge generally refers to a thickness gauge. The thickness gauge is made of thin steel sheets and consists of a group of gauge sheets with different thicknesses. It is mainly used to check the gap between two mating surfaces, so it is also called a "feeler gauge" or a "gap gauge". The thickness of each gauge sheet is marked in millimeters. By continuously adjusting the stacking of silicon wafers by the staff, the warpage degree of the battery wafers can be tested. However, the thickness of the silicon wafers used in the feeler gauge is fixed, and the warpage degree of some battery wafers is not fixed. The thickness of the feeler gauge may be higher or lower than the warpage degree of the battery wafers, thereby reducing the accuracy of the equipment for measuring the warpage degree of the battery wafers. Therefore, in order to solve the above problems, we propose a feeler gauge for testing the warpage degree of battery wafers. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a feeler gauge for testing the warpage degree of battery wafers, and adopts the following technical solutions:

[0005] A feeler gauge for testing the warpage degree of battery wafers, including a feeler gauge body. The feeler gauge body is wedge-shaped. A connecting block is fixedly installed on one side of the feeler gauge body. A scale is provided on the inclined surface of the feeler gauge body. Two symmetrically distributed support blocks are fixedly installed on the side of the connecting block away from the feeler gauge body, and a spirit level is arranged between the two support blocks. A clamping component is arranged between the spirit level and the two support blocks;

[0006] A column is rotatably installed at the top of the connecting block, and a mounting block is fixedly installed at the top of the column. A stop block is arranged on one side of the mounting block. A telescopic component is arranged between the stop block and the mounting block. An adsorption component is arranged at the bottom of the stop block.

[0007] By adopting the above technical solution, when the device is in use, the staff places the spirit level between the two supporting blocks, installs the spirit level on the side wall of the connecting block through the clamping component. Subsequently, the staff places the solar cell on the horizontal tabletop, then places the thickness gauge body on the horizontal tabletop, and observes whether the thickness gauge body maintains a horizontal state through the spirit level. When the thickness gauge body is adjusted, the staff adsorbs on the top of the solar cell through the adsorption component, which can play a role in restricting and positioning the thickness gauge body. Subsequently, the staff pushes the thickness gauge body towards the solar cell to place the thickness gauge body at the warped position at the bottom of the solar cell. By observing the scale on the side wall of the thickness gauge body, the warpage degree of the solar cell is then calculated. Through the setting of the telescopic component between the mounting block and the stop block, it can play a role in stabilizing the thickness gauge body, facilitating the stable movement of the thickness gauge body. The column is rotatably installed on the top of the connecting block, facilitating the staff to adjust the direction of the adsorption component.

[0008] Further, the clamping component includes clamping blocks fixedly installed on both sides of the spirit level. On the opposite sides of the two supporting blocks, clamping grooves matching the clamping blocks on the same side are opened, and sliding rods are fixedly installed in both of the two clamping grooves. The two clamping blocks are slidably sleeved on the side walls of the same group of sliding rods.

[0009] By adopting the above technical solution, the staff places the spirit level between the two supporting blocks, so that the clamping blocks installed on both sides of the spirit level are placed in the clamping grooves opened on the inner sides of the supporting blocks, and the clamping blocks are slidably sleeved on the side walls of the same group of sliding rods. Through the limitation of the clamping blocks, sliding rods and clamping grooves, the function of installing the spirit level can be achieved.

[0010] Further, the telescopic component includes a first support column fixedly installed on the side of the mounting block close to the stop block. A first movable groove is opened on the side of the first support column away from the mounting block, and a second support column is slidably installed in the first movable groove. A first spring is fixedly connected between the end of the second support column close to the mounting block and the inner wall of the side opposite to the first movable groove. A second movable groove is opened on the side of the second support column away from the mounting block, and a third support column is slidably installed in the second movable groove. A second spring is fixedly connected between the side of the third support column close to the mounting block and the inner wall of the side opposite to the second movable groove. A third movable groove is opened on the side of the third support column away from the mounting block, and a support rod is slidably installed in the third movable groove. A third spring is fixedly connected between the side of the support rod close to the mounting block and the inner wall of the side opposite to the third movable groove. The side of the support rod away from the mounting block is fixedly connected to the side opposite to the stop block.

[0011] By adopting the above technical solution, when the staff member pushes the feeler gauge body to move through the connecting block, the connecting block drives the upright post and the mounting block to move, the mounting block drives the first support pillar, the second support pillar, the third support pillar and the support rod to move synchronously, and the first support pillar, the second support pillar, the third support pillar and the support rod cooperate with the first spring, the second spring and the third spring to play a role in pulling the stop block, and the first support pillar, the second support pillar, the third support pillar and the support rod cooperate to play a role in restricting the moving direction of the feeler gauge body, facilitating the stable movement of the feeler gauge body.

[0012] Furthermore, two symmetrically distributed limiting blocks are fixedly installed on the side walls of the support rod, the third support pillar and the second support pillar near one end of the mounting block, and limiting grooves matching the limiting blocks of the same group are provided on the inner walls of the first moving groove, the second moving groove and the third moving groove.

[0013] By adopting the above technical solution, through the arrangement of the limiting blocks on the side walls of the support rod, the third support pillar and the second support pillar, when the support rod, the third support pillar and the second support pillar slide, the cooperation of the support rod, the third support pillar and the second support pillar with the limiting blocks located in the same-side limiting grooves is beneficial to maintaining the stability of the sliding of the support rod, the third support pillar and the second support pillar, and helps to prevent the support rod, the third support pillar and the second support pillar from detaching from the third moving groove, the second moving groove and the first moving groove.

Two symmetrically distributed sliders are fixedly installed on the side wall of the top end of the stabilizing rod, and a sliding groove matching the sliders is provided on the inner wall of the fourth moving groove.

[0015] By adopting the above technical solution, after the feeler gauge body is kept horizontal, the staff member pulls the stabilizing rod to slide in the fourth moving groove, so that the suction cup at the bottom end of the stabilizing rod contacts the top of the battery cell, and by pressing the suction cup to adsorb on the top of the battery cell, the function of stabilizing the feeler gauge body can be achieved, facilitating the stable movement of the feeler gauge body. And when the stabilizing rod slides in the fourth moving groove, the stabilizing rod drives the sliders to slide in the same-side sliding grooves. Through the cooperation of the sliders and the sliding grooves, it is beneficial to maintaining the stability of the sliding of the stabilizing rod and helps to prevent the stabilizing rod from detaching from the fourth moving groove.

[0016] Furthermore, an installation ring is fixedly sleeved on the side wall of the lower section of the upright post, a rubber pad is fixedly installed at the top end of the connecting block, and a bolt is provided at the top end of the installation ring. The bottom end of the bolt penetrates through the installation ring and contacts the top end of the rubber pad.

[0017] By adopting the above technical solution, after the rotation angle of the column is determined, the bolt is rotated downward so that the end of the bolt contacts the rubber pad installed at the top of the connecting block. By continuously rotating the bolt to press the rubber pad, the rotation of the installation ring can be restricted, and thus the column can be fixed.

[0018] Furthermore, a protective frame is sleeved on the side wall of the feeler gauge body. A magnetic sheet is fixedly installed on the inner wall of the protective frame near one end of the connecting block, and an iron sheet is sleeved on the side wall of the connecting block near the protective frame.

[0019] By adopting the above technical solution, the side wall of the feeler gauge body is protected by the protective frame, and the protective frame can be fixed by the attraction between the magnetic sheet and the iron sheet installed on the side wall of the connecting block.

A spirit level 18 is arranged between the two support blocks 4. A clamping component is arranged between the spirit level 18 and the two support blocks 4. The clamping component includes clamping blocks 181 fixedly installed on both sides of the spirit level 18. Slots 41 matching the clamping blocks 181 on the same side are opened on the opposite sides of the two support blocks 4. Slide bars 411 are fixedly installed in both slots 41. The two clamping blocks 181 are slidably sleeved on the side walls of the same group of slide bars 411. When the device is in use, the staff places the spirit level 18 between the two support blocks 4, makes the clamping blocks 181 installed on both sides of the spirit level 18 placed in the slots 41 opened on the inner sides of the support blocks 4, and makes the clamping blocks 181 slidably sleeved on the side walls of the same group of slide bars 411.

The bottom end of the stabilizing rod 14 is fixedly connected with a suction cup 15. Two symmetrically distributed sliders are fixedly installed on the side wall of the top end of the stabilizing rod 14. Sliding grooves matching the sliders are opened on the inner wall of the fourth moving groove 131. After the feeler gauge body 1 is leveled, the staff pulls the stabilizing rod 14 to slide in the fourth moving groove 131, so that the suction cup 15 at the bottom end of the stabilizing rod 14 contacts the top of the battery wafer. By pressing the suction cup 15 to adsorb on the top of the battery wafer, the function of stabilizing the feeler gauge body 1 can be achieved, which is convenient for the stable movement of the feeler gauge body 1. And when the stabilizing rod 14 slides in the fourth moving groove 131, the stabilizing rod 14 drives the sliders to slide in the sliding grooves on the same side. Through the cooperation of the sliders and the sliding grooves, it is beneficial to maintain the stability of the sliding of the stabilizing rod 14 and helps to prevent the stabilizing rod 14 from detaching from the fourth moving groove 131.

A bolt 19 is arranged at the top end of the installation ring 5. The bottom end of the bolt 19 penetrates through the installation ring 5 and contacts the top end of the rubber pad. After the rotation angle of the column 6 is determined, by rotating the bolt 19 downward, the end of the bolt 19 contacts the rubber pad installed at the top end of the connecting block 3. By continuously rotating the bolt 19 to press the rubber pad, the function of restricting the rotation of the installation ring 5 can be achieved, and thus the function of fixing the column 6 can be achieved.

[0038] A column 6 is rotatably installed at the top of the connecting block 3, and a mounting block 7 is fixedly installed at the top of the column 6. A stop block 12 is provided on one side of the mounting block 7. A telescopic assembly is provided between the stop block 12 and the mounting block 7.

The side of the support rod 11 away from the mounting block 7 is fixedly connected to the side opposite to the stop block 12.

[0039] When the staff moves the feeler gauge body 1 by pushing the connecting block 3, the connecting block 3 drives the column 6 and the mounting block 7 to move. The mounting block 7 drives the first support column 8, the second support column 9, the third support column 10 and the support rod 11 to move synchronously. And through the cooperation of the first spring 811, the second spring 911 and the third spring 1011 between the first support column 8, the second support column 9, the third support column 10 and the support rod 11, it plays a role in pulling the stop block 12. And through the cooperation of the first support column 8, the second support column 9, the third support column 10 and the support rod 11, it plays a role in restricting the moving direction of the feeler gauge body 1, facilitating the stable movement of the feeler gauge body 1. Two symmetrically distributed limiting blocks are fixedly installed on the side walls of the ends of the support rod 11, the third support column 10 and the second support column 9 close to the mounting block 7. Limiting grooves matching the same group of limiting blocks are formed on the inner walls of the first movable groove 81, the second movable groove 91 and the third movable groove 101. Through the arrangement of the limiting blocks on the side walls of the support rod 11, the third support column 10 and the second support column 9, when the support rod 11, the third support column 10 and the second support column 9 slide, the cooperation of the limiting blocks on the support rod 11, the third support column 10 and the second support column 9 located in the same-side limiting grooves is beneficial to maintaining the stability of the sliding of the support rod 11, the third support column 10 and the second support column 9, and helps to prevent the support rod 11, the third support column 10 and the second support column 9 from disengaging from the third movable groove 101, the second movable groove 91 and the first movable groove 81.

[0040] A protective frame 16 is sleeved on the side wall of the feeler gauge body 1. A magnetic sheet 17 is fixedly installed on the inner wall of the protective frame 16 near one end of the connecting block 3. An iron sheet 2 is sleeved on the side wall of the connecting block 3 near the protective frame 16. The arrangement of the protective frame 16 on the side wall of the feeler gauge body 1 plays a role in protecting the feeler gauge body 1. And the magnetic sheet 17 attracts the iron sheet 2 installed on the side wall of the connecting block 3, which can play a role in fixing the protective frame 16.

[0041] The implementation principle of the embodiment of the present utility model is as follows: When the device is in use, the staff places the level 18 between the two support blocks 4 and installs the level 18 on the side wall of the connecting block 3 through the clamping assembly. Subsequently, the staff places the battery cell on the horizontal tabletop, and then places the feeler gauge body 1 on the horizontal tabletop. The staff observes whether the feeler gauge body 1 is in a horizontal state through the level 18. When the feeler gauge body 1 is adjusted, the staff adsorbs on the top of the battery cell through the adsorption assembly, which can play a role in restricting and positioning the feeler gauge body 1. Then, the staff pushes the feeler gauge body 1 towards the battery cell, so that the feeler gauge body 1 is placed at the warped position at the bottom of the battery cell. By observing the scale on the side wall of the feeler gauge body 1 and then calculating, the warpage degree of the battery cell can be obtained. The arrangement of the telescopic assembly between the mounting block 7 and the stop block 12 can play a role in stabilizing the feeler gauge body 1, facilitating the stable movement of the feeler gauge body 1. The column 6 is rotatably installed on the top of the connecting block 3, which is convenient for the staff to adjust the direction of the adsorption assembly. When the rotation angle of the column 6 is determined, the bolt 19 is lowered by rotation, so that the end of the bolt 19 contacts the rubber pad installed at the top of the connecting block 3. By continuously rotating the bolt 19 to press the rubber pad, the rotation of the mounting ring 5 can be restricted, thereby playing a role in fixing the column 6.

[0042] The above are all the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited hereby.
