[0002] The battery screen is an important tool for printing the positive and negative electrodes of solar cells. It has the characteristics of high precision and high durability. In the production process of photovoltaic cells, the battery screen plays a vital role.

[0003] The surface of the existing high-precision battery screen is usually attached with protective materials. During the attachment process, the protective materials are pressed to make them firm and beautiful. However, most of the existing attachment methods use a fixed positioning fixture to support the screen, and then use a direct pressing method to press the protective material onto the screen. The direct pressing attachment method often causes poor parameter performance due to uneven force. In severe cases, it can cause the screen to crack and explode. Secondly, the protective materials are attached on all four sides, and the screen is constantly moved during the attachment process, which is inefficient and has the risk of explosion. To this end, those skilled in the art provide a rotating positioning fixture in the process of making the screen to solve the problems raised in the above background technology.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution for a rotary positioning fixture in the process of making a screen: the rotary positioning fixture in the process of making a screen includes a rotary table 1 and a carrier plate 2. The rotary table 1 includes a supporting base 11. A rotating seat 12 is provided in the middle of the plate frame of the supporting base 11, and a rotating shaft 13 of a top support locking rod 3 is rotatably connected inside the shaft sleeve of the rotating seat 12. The supporting base 11 is a bakelite structure. By setting the supporting base 11 as a bakelite structure, it has good flat support and counterweight support performance, and then the combination of the rotating seat 12 and the rotating shaft 13 is used as a rotating support component to support the carrier plate 2 for rotation transmission.

[0025] The carrier plate 2 includes a first carrier plate 21 and a second carrier plate 22 arranged flush with each other. The bottom plate of the first carrier plate 21 is arranged with multiple groups of guide slots 23, and the bottom plate of the second carrier plate 22 is arranged with multiple groups of guide buckles 24 opposite to the guide slots 23, and the guide slots 23 and the guide buckles 24 are interference fit with each other. The carrier plate 2 is made of transparent acrylic plate material. By setting the carrier plate 2 as a transparent acrylic plate material, it has better visibility, which is conducive to observing the attachment of the screen and its protective material. By setting the carrier plate 2 as a detachable first carrier plate 21 and a second carrier plate 22, it is convenient to disassemble and assemble them so as to open and close the locking tool 4.

[0026] The rotating axis of the turntable 1 is provided with multiple groups of locking rods 3 arranged along its circumference, the bottom plate of the carrier plate 2 is provided with a locking fixture 4, and the turntable 1 and the carrier plate 2 are fixed by locking rods 3 and locking fixture 4. The locking fixture 4 includes a locking shell 41 installed on the bottom plate of the locking fixture 4 and multiple groups of locking arms 42 arranged along the circumference of the locking shell 41. The top end of the arm rod of each group of locking arms 42 is provided with a positioning through hole 43 that guides and adapts to the locking rod 3. By utilizing the one-to-one correspondence between the positioning through hole 43 and the locking rod 3, the locking fixture 4 is inserted into the locking rod 3 in a buckled manner, and the carrier plate 2 and the turntable 1 are preliminarily aligned and installed.

[0027] A knob 44 is provided in the middle of the housing of the locking shell 41, and a track plate 45 is installed on the output shaft of the knob 44. The guide rail of the track plate 45 is connected to a plurality of track slides 46 along its circumferential sliding direction, and an arm force rod 47 extending to the inside of the support arm of the locking arm 42 is provided on one side of the stand of each group of track slides 46. A locking sleeve 48 is provided on the top of the arm of the arm force rod 47 to match the locking card slot 32. The locking plug rod 3 includes a plurality of groups of positioning rods 31 arranged along the circumference of the rotating axis of the rotating table 1, and a locking card slot 32 is provided in the middle of the support rod of each group of positioning rods 31. The track plate 4 5 is a spiral guide structure. After the carrier plate 2 and the rotating table 1 are initially installed, the knob 44 is turned with a screwdriver to drive the track plate 45 to rotate. The track plate 45 and the guide rail of the track slide 46 slide to convert the rotational force into a horizontal thrust, pushing the arm force rod 47 to slide along the arm rod direction of the locking arm 42, pushing out the locking sleeve 48 and snapping it into the locking slot 32 of the locking plug rod 3 to form a locked state. The carrier plate 2 and the rotating table 1 can be assembled and fixed as a whole. When the carrier plate 2 is replaced later, it is only necessary to unlock the locking tool 4 in the reverse direction to disassemble and replace the carrier plate 2.

[0028] The working principle of the present invention is as follows: when using the rotary positioning fixture as the carrier platform for installing the battery screen, the matching carrier plate 2 is replaced in advance according to the model of the screen, and then during the replacement and installation process, the alignment through holes 43 and the locking plug rods 3 are first used to correspond one to one, and the lock tooling 4 is inserted into the locking plug rod 3 in a buckle manner to perform preliminary alignment installation on the carrier plate 2 and the rotary table 1, and then the knob 44 is turned by a screwdriver tool to drive the track plate 45 to rotate, and the track plate 45 and the guide rail of the track slide 46 are used to slide, and the rotational force is converted into a horizontal thrust, which pushes the arm force rod 47 to slide along the arm direction of the locking arm 42, and the locking sleeve 48 is pushed out and snapped into the locking slot 32 of the locking plug rod 3 to form a locked state, thereby completing the integrated assembly and fixation of the carrier plate 2 and the rotary table 1;

[0029] In the subsequent production process of the screen, when the protective material is attached to the screen, the rotating base 12 and the rotating shaft 13 in the rotating table 1 can be used as a rotating support component to support the carrier plate 2 for rotational transmission, so that the protective material attached to the screen is attached in a rotating force-bearing manner. The attachment force is more evenly dispersed, the attachment quality is better, and the adverse conditions caused by uneven pressure can be effectively reduced.

[0030] Furthermore, when producing different types of screens, it is only necessary to unlock the knob of the locking fixture 4 to replace the corresponding carrier plate 2.

[0031] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
