Technical Field

[0001] This utility model relates to the field of diode processing technology, and specifically to an etching device for photovoltaic diodes. Background Technology

[0002] Existing diode etching equipment fixes the diode in a fixed groove during the etching process. However, due to the small gap between the fixed groove and the diode, the etching solution cannot fully contact the diode, resulting in unqualified etching.

[0003] Prior art CN221994426U discloses an etching apparatus for diode manufacturing, including a housing. An etching solution tank is located on the inner surface of the housing, and an etching plate is located above the etching solution tank. A swing assembly connected to the etching plate is located on the upper surface of the housing. The swing assembly includes a dual-axis motor mounted on the upper surface of the housing. A first rotating shaft is connected to both ends of the output shaft of the dual-axis motor. A first elastic rope and a second elastic rope, arranged obliquely symmetrically, are wound around the outer surface of the first rotating shaft. The swing assembly also includes oblique connecting rods located on both sides of the etching plate. A lifting assembly is connected to both ends of the oblique connecting rods, and a second rotating shaft connected to the lifting assembly is rotatably connected to the housing of the oblique connecting rods. This invention solves the problem of insufficient contact between the etching solution and the diode by using the swing assembly to ensure full contact between the etching solution and the diode.

[0004] When using the above-mentioned device, the applicant discovered that: rectangular guide grooves are vertically arranged on both sides of the device's housing. This structure makes it easy for external impurities to enter the interior through the grooves during the etching process of the diode, which can easily cause etching solution contamination and seriously affect the diode etching process. Utility Model Content

[0005] The purpose of this invention is to provide an etching device for photovoltaic diodes, in order to solve the problem that in existing devices, external impurities can easily enter the interior during diode etching, causing etching solution contamination and seriously affecting the diode etching process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an etching device for photovoltaic diodes, including a housing, an electrical control cabinet is provided on the rear side of the housing, a controller is provided on the left side, the controller is electrically connected to the electrical control cabinet, a protective door is installed on the front side via a hinge, and an etching component is also included.

[0007] The etching assembly includes a liquid storage tank, an etching plate, a filter cover, a locking pin, a power component, and a guide component. The liquid storage tank is fixed to the bottom of the housing body. The etching plate is located above the liquid storage tank. Several etching grooves are spaced apart on the etching plate. The etching grooves are arranged from top to bottom without penetrating through, and each etching groove has a penetrating etching hole at its bottom. The filter cover is detachably connected to the etching plate and is located on the top of the etching plate. The locking pin is slidably connected to the filter cover and threadedly connected to the etching plate, and is symmetrically arranged on the front side of the etching plate.

[0023] The liquid storage tank 105 is fixed to the bottom of the housing 101. The etching plate 106 is located above the liquid storage tank 105. Several etching grooves 107 are spaced apart on the etching plate 106. The etching grooves 107 are arranged from top to bottom without penetrating.

The locking pin 110 is slidably connected to the filter cover 109 and threadedly connected to the etching plate 106. It is symmetrically arranged on the front side of the etching plate 106. The power component is located on the left side of the etching plate 106, and the guide component is located on the right side of the etching plate 106. The four perforated mounting ears on both sides of the bottom of the liquid storage tank 105 are fixed by bolts and can store etching solution. The etching tank 107 is used for diode placement, and the etching hole 108 through the bottom facilitates the etching solution to contact the diode. The etching plate 106 is provided with four short cylinders to facilitate the installation of the filter cover 109. The two symmetrical mounting parts on the front side of the filter cover 109 are provided with through holes. The two short cylinders on the front side of the etching plate 106 are provided with threaded holes to facilitate the threaded end of the locking pin 110. The locking pin 110 is composed of a stepped optical axis end on the front side, a limiting circular plate in the middle, and a rotating plate at the rear. The stepped optical axis end has an external threaded end on the most front stepped part. The power component is used to drive the etching plate 106 downward, and the guide component is used to improve the downward stability of the etching plate 106.

[0024] Secondly, the horizontal plate 111 is fixed inside the housing 101 and located above the filter cover 109; the servo electric cylinder 112 is electrically connected to the electrical control cabinet 102 and fixed on the horizontal plate 111; the left bracket 113 is connected to the etching plate 106 and the output end of the servo electric cylinder 112 respectively, and is located on the left side of the etching plate 106.

One end of the left bracket 113 is fixed to the output end of the servo electric cylinder 112 by bolts, and the other end is fixed to the etching plate 106 by bolts. The housing 101 is provided with a through hole through which the working cable of the servo electric cylinder 112 just passes.

[0025] Then, the right bracket 114 is fixedly connected to the etching plate 106 and is located on the side of the etching plate 106 away from the left bracket 113; the guide rod 115 is detachably connected to the housing 101, passes through the horizontal plate 111, and is slidably connected to the right bracket 114.

[0027] When using this invention to address the problem in existing devices where external impurities easily enter the diode etching process, causing etching solution contamination and severely affecting the process, the following steps are taken: First, the etching solution is added to the storage tank 105. Then, the diode is placed in the etching groove 107 of the etching plate 106, and the filter cover 109 is installed using the locking pin 110. Next, the protective door 104 is closed. Furthermore, the controller 103 controls the servo electric cylinder 112 to push the left support 113 downwards, and with the assistance of the guide member, drives the etching plate 106 downwards, immersing it in the etching solution. At this point, the filter cover 109 facilitates the contact between the etching solution and the diode, and also partially reduces the contact between impurities in the etching solution and the diode. Furthermore, the housing 101 in this application does not have sliding groove structures on both sides, thus preventing external impurities from easily entering the diode etching process and reducing etching solution contamination. This effectively solves the problem in existing devices where external impurities easily enter the diode etching process, causing etching solution contamination and severely affecting the process.
