Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tank type cleaning machine, specifically a tank type cleaning machine mechanical hand clamp jaw cleaning device. BACKGROUND

[0002] In order to ensure the performance and efficiency of solar cells, the front side of the silicon wafer needs to be properly protected, and the back side and the peripheral edge of the silicon wafer need to be removed. At the same time, in order to enhance the light absorption capacity of the solar cell, the back side of the silicon wafer also needs to be polished.

[0003] At present, the industry generally uses a tank type cleaning machine to complete this series of complex silicon wafer processing steps. The tank type cleaning machine puts the flower basket loaded with silicon wafers into the tank body equipped with specific chemical liquid through the mechanical arm. In the tank body, the silicon wafers react with the chemicals to polish the back side of the silicon wafers. Subsequently, the silicon wafers are cleaned through the water tank to remove the residual chemicals. Finally, the silicon wafers are dried through the drying tank to achieve the purpose of cleaning and polishing the back side of the silicon wafers.

[0004] However, the tank type cleaning machine also exposes some significant problems in the use process. Since high-concentration lye is used in the tank body, when the mechanical arm frequently enters and exits the tank type machine to take and place the flower basket loaded with silicon wafers, a large amount of lye crystals will accumulate on the mechanical arm. These crystals not only cause corrosion to the inductors on the mechanical arm, but also may cause the inductors to mis-sense and issue an alarm signal. Once the inductors are damaged or issue a false alarm, the mechanical arm may stop working, thereby causing the silicon wafers to be stranded in the tank body. INVENTION CONTENTS

[0005] To solve the technical problems in the background art, the utility model discloses a tank type cleaning machine mechanical hand clamp jaw cleaning device.

[0006] The utility model provides a tank type cleaning machine mechanical hand clamp jaw cleaning device is installed on the water tank, and it includes:

[0007] The lifting plate is driven to lift by the driving assembly;

[0008] The lifting plate is arc-shaped and is arranged symmetrically in two pieces, and the moving path of the lifting plate is arc-shaped;

[0009] When the lifting plate rises, the upper ends thereof are in contact with each other and form a semicircular arc shape with the opening downward, and a flushing cavity is formed between the lifting plate and the water tank, and at this time, the clamp jaw is located in the flushing cavity;

[0010] The upper end of the lifting plate is provided with a nozzle, and the jet direction of the nozzle is directly opposite to the clamp jaw.

[0011] The beneficial effects of the above arrangement are: 1. The jet direction of the nozzle is directly opposite to the clamping jaw, which can flush the alkali liquor crystals on the clamping jaw in all directions without dead angle, effectively preventing the corrosion of the crystals on the inductor; 2. The cleaning device of the utility model is installed on the sink, which is simple and compact, easy to integrate with the existing tank type cleaning machine; 3. The nozzle flushes the clamping jaw while flushing the silicon wafer, so no additional time is wasted, and the production efficiency will not be affected by the clamping jaw cleaning; 4. The wastewater after cleaning the clamping jaw directly flows into the sink and is treated together with the wastewater from the silicon wafer cleaning, without additional cost.

[0012] To improve the stability of the lifting plate, further design is: a guide groove is arranged in the sink; guide blocks are arranged at both ends of the lifting plate to clamp the guide groove.

[0013] The specific structure of the guide groove is: the guide groove comprises a guide rod; the guide rod constitutes the guide groove by bending.

[0014] The lifting plate is arranged in a fixed arc shape, which will occupy too much space in the sink when it is lowered, resulting in insufficient space in the sink to place the flower basket; the space problem has not been solved, and the volume of the sink needs to be increased, which will increase the cost. Therefore, further improvement is that the lifting plate is composed of a plurality of link plates hingedly connected in sequence; the part of the guide groove located at the upper end of the sink is in a semicircular arc shape; the part of the guide groove located in the sink is arranged vertically. In this way, when the lifting plate is lowered, the lifting plate is arranged in a straight and vertical manner and is located close to the inner wall of the sink; when the lifting plate is raised, the lifting plate rotates under the action of the guide groove and forms an arc shape.

[0015] The specific structure of the guide rod is: the guide rod comprises a first arc-shaped rod and a second arc-shaped rod arranged concentrically in a semicircular arc shape, the upper ends of the first arc-shaped rod and the second arc-shaped rod are connected by a third arc-shaped rod and form an arc-shaped groove with the opening facing downward, the diameter of the second arc-shaped rod is smaller than that of the first arc-shaped rod, the lower end of the second arc-shaped rod is connected with a vertically arranged connecting rod, a straight groove is formed between the connecting rod and the inner groove wall of the sink, and the lower end of the arc-shaped groove is communicated with the upper end of the straight groove to form the guide groove.

[0016] The driving assembly is: it comprises a speed reducer motor, a winding wheel is installed on the driving end of the speed reducer motor, one end of the pull rope is wound on the winding wheel, and the other end is fixedly connected with the lifting plate. In this way, when the winding wheel is wound, the lifting plate is driven to rise; when the winding wheel is unwound, the lifting plate automatically descends under the action of gravity.

[0017] Since the lifting plate is symmetrically arranged in two pieces, two sets of speed reducer motors are generally used for separate driving. In this way, not only the cost is high, but also the synchronicity is low. Therefore, further improvement is that the speed reducer motor is a worm gear reducer, a driving shaft is installed on the driving end of the speed reducer motor, the driving shaft extends outward from both ends of the driving end of the speed reducer motor, and the winding wheels are arranged at both ends of the driving shaft.

[0018] The connecting position of the pull rope and the lifting plate directly affects the stability of the lifting plate lifting, and based on this, the further improvement is that the other end of the pull rope is fixedly connected with the lower end of the lifting plate.

[0019] When the pull rope passes through the upper end of the side wall of the sink, the position of the part connected with the sink is unstable, and pressure is easily generated between the pull rope and the edge of the sink, and the pull rope is cut off by the edge of the sink, and based on this, the further improvement is that a roller is installed on the top of the sink, and the pull rope passes through the upper side of the roller.

[0020] The structure of the guide block directly affects the resistance of the lifting plate lifting, and based on this, the further improvement is that the guide block is spherical, and the diameter of the guide block is greater than the groove width of the guide groove; the guide block is arranged between the guide rod and the groove wall of the sink.

[0021] The beneficial effects of the utility model are: 1. the spraying direction of the nozzle is opposite to the clamping jaw, can all -round, no dead angle flush away the alkali liquor crystallization on the clamping jaw, effectively prevent the corrosion of the crystallization to the inductor;2. the cleaning device of the utility model is installed on the sink, simple structure, compact, easy to integrate with the existing tank -type cleaning machine;3. while flushing the silicon wafer, the nozzle flushes the clamping jaw, therefore does not need to spend additional time, will not cause the clamping jaw cleaning to influence production efficiency;4. the wastewater after cleaning the clamping jaw directly flows into the sink, and is treated together with the wastewater of the silicon wafer cleaning, will not increase additional cost.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] like Figures 1-3 As shown, this utility model discloses a robotic gripper cleaning device for a trough-type cleaning machine, installed on a water tank 1, including a lifting plate 2. The lifting plate 2 is configured as two symmetrically arranged pieces, installed inside the water tank 1. The specific installation structure is as follows: symmetrically arranged guide rods 7 are installed at both ends of the length direction inside the water tank 1. Figure 4 As shown, the guide rod 7 includes a semi-circular arc-shaped first arc rod 71 and a second arc rod 72 arranged concentrically. The upper ends of the first arc rod 71 and the second arc rod 72 are connected by a third arc rod 73, forming a downward-opening arc groove 51. The diameter of the second arc rod 72 is smaller than that of the first arc rod 71. A vertically arranged connecting rod 74 is connected to the lower end of the second arc rod 72. The lower end of the first arc rod 71 is welded to the upper end of the water tank 1, and the lower end of the connecting rod 74 is welded to the bottom of the water tank 1. A straight groove 52 is formed between the connecting rod 74 and the inner wall of the water tank 1. The lower end of the arc groove 51 communicates with the upper end of the straight groove 52, forming a guide groove 5.

[0031] like Figure 5 As shown, the lifting plate 2 is composed of multiple connecting plates 21 that are hinged together in sequence. The hinge shaft passes through both ends of the connecting plates 21, and each end of the hinge shaft is equipped with a spherical guide block 6. One end of the guide block 6 is equipped with a screw, which is threadedly connected to the end of the hinge shaft. The diameter of the guide block 6 is larger than the width of the guide groove 5. The guide block 6 is positioned between the guide rod 7 and the wall of the water tank 1, simultaneously abutting against the first arc-shaped rod 71 and the second arc-shaped rod 72, or simultaneously abutting against the inner wall of the water tank 1 and the second arc-shaped rod 72. This achieves the installation limitation of the lifting plate 2 and, under the action of the guide groove 5, enables its movement guidance.

[0032] The structure of the lifting plate 2 is designed so that when the lifting plate 2 descends, it is arranged in a straight and vertical position and is located close to the inner wall of the water tank 1. In this way, the lifting plate 2 occupies little space in the water tank 1, and the basket containing silicon wafers can still be accommodated without increasing the volume of the water tank 1. When the lifting plate 2 rises, it rotates under the action of the guide groove 5 to form an arc.

[0033] When the lifting plates 2 rise, their upper ends contact each other and form a downward-facing semi-circular arc, which together with the water tank 1 forms a rinsing chamber 3. At this time, the grippers are located inside the rinsing chamber 3. A nozzle 4 is installed at the lower end of the top connecting plate 21, and the spray direction of the nozzle 4 is directly facing the grippers.

[0034] The advantages of the above arrangement are: 1. The jet direction of the nozzle 4 is directly opposite to the clamping jaw, which can flush the alkali liquor crystals on the clamping jaw in all directions without dead angle, effectively preventing the corrosion of the crystals on the inductor; 2. The cleaning device of the utility model is installed on the water tank 1, which is simple and compact, easy to integrate with the existing tank type cleaning machine; 3. The nozzle 4 flushes the clamping jaw while flushing the silicon wafer, so no additional time is wasted, and the production efficiency will not be affected by the clamping jaw cleaning; 4. The wastewater after cleaning the clamping jaw directly flows into the water tank 1 and is treated together with the wastewater from the silicon wafer cleaning, without additional cost.

[0035] Due to the third arc-shaped rod 73, there will be a gap between the top of the lifting plate 2, and the sprayed water is easy to spray outward between the lifting plate 2, so the end of the top connecting plate 21 is provided with a brush 13. When the lifting plate 2 rises, the two side brushes 13 are staggered with each other, so that the gap between the top of the lifting plate 2 is blocked by the brush 13, not only can avoid water spray out, but also the clamping jaw will slide relative to the brush 13 when lifting, and the impurities on the clamping jaw and water can be scraped off by the brush 13, so that no water droplets will fall when the clamping jaw moves.

[0036] The lifting plate 2 is driven to lift by the driving assembly, and the specific structure is that the bottom of the water tank 1 is provided with a speed reducer motor 8, which is a worm gear reducer, and the driving end is provided with a driving shaft 11. The driving shaft 11 extends outward from the two ends of the driving end of the speed reducer motor 8, and the two ends of the driving shaft 11 are both provided with a winding wheel 9. One end of the pull rope 10 is fixedly connected with the lifting plate 2, and the other end is wound on the winding wheel 9. When the speed reducer motor 8 drives the winding wheel 9 to wind, the lifting plate 2 rises; when the speed reducer motor 8 drives the winding wheel 9 to unwind, the lifting plate 2 descends under the action of gravity. Thus, two lifting plates 2 are driven to lift by one speed reducer motor 8, which not only reduces the cost, but also improves the synchronization of the lifting plate 2 movement. Furthermore, the speed reducer motor 8 is installed at the lower end of the water tank 1, which does not occupy the space around the water tank 1, so that the main structure of the tank type cleaning machine does not need to be changed, thereby reducing the cost.

[0037] One end of the pull rope 10 is fixedly connected with the lowermost end connecting rod 74, so that one end of the pull rope 10 only moves vertically, which can improve the stability of the lifting plate 2 rising.

[0038] A roller seat is further arranged at the upper end of the water tank 1, and a movable roller 12 is arranged on the roller seat. The side surface of the roller 12 is concave and arc-shaped, and the pull rope 10 passes through the center of the upper side of the roller 12. Thus, it not only avoids the risk that the pull rope 10 is cut off by the edge of the water tank 1 when it is connected to the top of the water tank 1, but also limits the pull rope 10, so that it can be stably wound and unwound.

[0039] With the above ideal embodiment of the present application as the inspiration, through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and the technical scope must be determined according to the scope of claims.
