Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning technology, specifically to an ultrasonic cleaning fixture for photovoltaic samples. Background Technology

[0002] Ultrasonic cleaning utilizes the cavitation, acceleration, and direct flow effects of ultrasound waves in liquids to directly and indirectly act on the liquid and contaminants, thereby dispersing, emulsifying, and peeling off the contaminant layer to achieve the cleaning purpose.

[0003] Before testing, photovoltaic samples need to be cleaned by ultrasonic cleaning. During cleaning, fixtures are used to fix the samples to avoid direct friction and collision between them, and also to prevent excessive shaking of the samples caused by ultrasonic vibration and impact on the cleaning tank wall. Most existing ultrasonic cleaning fixtures for photovoltaic samples cannot clean multiple photovoltaic samples at the same time, which is not convenient for batch testing. Moreover, most existing ultrasonic cleaning fixtures for photovoltaic samples require manual unloading after cleaning. The surface of the photovoltaic samples is relatively smooth after cleaning, and manual unloading is inconvenient and has the risk of slipping. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic cleaning fixture for photovoltaic samples to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaning fixture for photovoltaic samples, comprising a cleaning chamber, inside which are placed two support plates. Several limiting clamps are installed at the opposite ends of the two support plates, with two limiting clamps forming a group. The bottom of each group of two limiting clamps is provided with an inclined end, and a slot is opened at the opposite ends of each group of two limiting clamps. Four reset components are connected between the limiting clamps and the corresponding support plates. Two brackets are installed at the top of each of the two support plates. Electric push rods are installed inside each of the four brackets, extending out of the bottom of the brackets. L-shaped fixing frames are installed at the bottom ends of the four electric push rods. One end of each of the four L-shaped fixing frames is connected to a material-bearing base. A protective fence is provided at the top edge of the material-bearing base, and inclined protrusions are provided at both ends of the protective fence.

[0006] Preferably, a protective cover is hinged to one end of the top of the cleaning chamber. When performing ultrasonic cleaning of photovoltaic samples, the protective cover is put on to seal the top of the cleaning chamber and prevent the cleaning fluid from splashing out from the top of the cleaning chamber during ultrasonic cleaning.

[0007] Preferably, a retaining plate is provided at the top edge of one end of each of the two support plates, and two positioning grooves matching the retaining plates are provided at the upper end of the inner cavity of the cleaning chamber. When the photovoltaic sample is placed into the cleaning chamber for cleaning by means of the support plates, the retaining plates and the corresponding positioning grooves are used to limit the support plates, so that the support plates can be fixedly placed inside the cleaning chamber.

[0008] Preferably, the two supports are grouped together, and the top of each pair of supports is connected to a handrail. After the material is loaded outside the cleaning chamber, the tooling can be picked up with the help of the handrail and placed into the cleaning chamber.

[0009] Preferably, a reinforcing insert is provided at one end of each of the limiting clamps near the middle of the corresponding support plate. The reinforcing insert is inserted into the support plate to reinforce the limiting clamps and ensure that each group of two limiting clamps can fix the photovoltaic sample.

[0010] Preferably, the top of the inclined convex plate matches the inclined end. When the inclined convex plate is driven to move upward, the top of the inclined convex plate first contacts the inclined end of the bottom of the lowest set of limiting clamps, pushing the two limiting clamps to move in the direction of the corresponding support plate. The photovoltaic sample clamped by the two limiting clamps will fall off and fall into the top of the material support base. The material support base continues to rise and contacts the inclined end of the bottom of the limiting clamp in sequence to perform the unloading operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This ultrasonic cleaning fixture for photovoltaic samples is used in conjunction with a liftable support base and limiting clamps. After the photovoltaic sample is cleaned, the support base moves linearly upward from the bottom of the support plate. The top of the inclined convex plate first contacts the inclined end of the bottom of the lowest set of limiting clamps, pushing the two limiting clamps to open. The photovoltaic sample will fall off and land on the top of the support base. The unloading operation is carried out from the bottom in sequence, and the sample is removed from the corresponding two limiting clamps for draining, making it easy to handle the photovoltaic sample.

[0013] 2. This ultrasonic cleaning fixture for photovoltaic samples, through several sets of vertically arranged limiting clamps, allows the same batch of photovoltaic samples to be cleaned simultaneously, facilitating subsequent inspection operations. Attached Figure Description

[0021] like Figures 1 to 4As shown, the ultrasonic cleaning fixture for photovoltaic samples in this embodiment includes a cleaning chamber 1. Two support plates 3 are placed inside the cleaning chamber 1. Several limiting clamps 7 are installed at the opposite ends of the two support plates 3. Two limiting clamps 7 form a group. Each group of two limiting clamps 7 has a beveled end 16 at its bottom and a slot 15 at the opposite ends of each group of two limiting clamps 7. Four reset components 17 are connected between the limiting clamps 7 and their corresponding support plates 3. The groups of limiting clamps 7 are vertically arranged between the two support plates 3. Each reset component 17 contains a telescopic rod and a spring. During photovoltaic sample cleaning, several photovoltaic samples are fixed between a group of limiting clamps 7, and the slots 15 limit the ends of the photovoltaic samples, facilitating simultaneous cleaning of multiple photovoltaic samples. Two brackets 10 are installed at the top of each of the two support plates 3. Each of the four brackets 10 has a... There are electric push rods 13, which extend from the bottom of the bracket 10. Each of the four electric push rods 13 has an L-shaped fixing bracket 14 installed at its bottom. One end of each of the four L-shaped fixing brackets 14 is connected to a material support base 6. A protective fence 12 is provided at the top edge of the material support base 6. Inclined protrusions 11 are provided at both ends of the protective fence 12. The four electric push rods 13 can drive the material support base 6 to move linearly up and down. When the material support base 6 moves linearly upward from the bottom of the support plate 3, the top of the inclined protrusion 11 first contacts the inclined end 16 at the bottom of the lowest set of limiting clamps 7, pushing the two limiting clamps 7 to move slowly towards the corresponding support plate 3. The photovoltaic sample clamped by the two limiting clamps 7 will fall off and fall into the top of the material support base 6. The material support base 6 continues to rise and contacts the inclined end 16 at the bottom of the limiting clamps 7 in turn to perform the unloading operation.

[0022] Specifically, a protective cover 2 is hinged to one end of the top of the cleaning chamber 1. When performing ultrasonic cleaning of photovoltaic samples, the protective cover 2 is put on to seal the top of the cleaning chamber 1 and prevent the cleaning fluid from splashing out from the top of the cleaning chamber 1 during ultrasonic cleaning.

[0023] Furthermore, a retaining plate 5 is provided at the top edge of one end of each of the two support plates 3. Two positioning grooves 4 matching the retaining plates 5 are provided at the upper end of the inside of the cleaning chamber 1. When the photovoltaic sample is placed into the cleaning chamber 1 for cleaning through the support plate 3, the retaining plate 5 and the corresponding positioning groove 4 work together to limit the support plate 3, so that the support plate 3 can be fixedly placed inside the cleaning chamber 1.

[0024] Furthermore, the two supports 10 are grouped together, and the top of each pair of supports 10 is connected to a handrail 9. After the material is loaded outside the cleaning chamber 1, the tooling can be picked up with the help of the handrail 9 and placed inside the cleaning chamber 1.

[0025] Furthermore, a reinforcing insert plate 8 is provided at one end of several limiting clamps 7 near the middle position of the corresponding support plate 3. The reinforcing insert plate 8 is inserted into the support plate 3 to reinforce the limiting clamps 7, ensuring that each group of two limiting clamps 7 can fix the photovoltaic sample.

[0026] Furthermore, the top of the inclined convex plate 11 matches the inclined end 16. When the inclined convex plate 11 is driven to move upward, the top of the inclined convex plate 11 first contacts the inclined end 16 at the bottom of the lowest set of limiting clamps 7, pushing the two limiting clamps 7 to move towards the corresponding support plate 3. The photovoltaic sample clamped by the two limiting clamps 7 will fall off and fall into the top of the material support base 6. The material support base 6 continues to rise and contacts the inclined end 16 at the bottom of the limiting clamps 7 in turn to perform the unloading operation.

[0027] The method of use in this embodiment is as follows: When using the photovoltaic sample ultrasonic cleaning fixture, firstly, fix the photovoltaic samples sequentially between several sets of vertically arranged limiting clamps 7 outside the cleaning chamber 1, so that several photovoltaic samples are placed vertically between two support plates 3, which facilitates centralized cleaning of the same batch of samples. After the photovoltaic samples are placed, place the fixture inside the cleaning chamber 1. The clamping plate 5 and the corresponding positioning groove 4 cooperate to limit the support plate 3, so that the support plate 3 can be fixedly placed inside the cleaning chamber 1. After cleaning, the four electric push rods 1 The drive base 6 moves linearly upward from the bottom of the support plate 3. The top of the inclined convex plate 11 first contacts the inclined end 16 at the bottom of the lowest set of limiting clamps 7, pushing the two limiting clamps 7 to move slowly towards the corresponding support plate 3. The photovoltaic sample clamped by the two limiting clamps 7 will fall off and land on the top of the base 6. The base 6 continues to rise and contacts the inclined end 16 at the bottom of the limiting clamps 7 in sequence to perform the unloading operation, removing the sample from between the corresponding two limiting clamps 7 for draining.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
