Description
Technical Field
[0001] This invention relates to the field of photovoltaic production equipment technology, and in particular to a feeding device for a wafer insertion machine that prevents chipping. Background Technology
[0002] During the production of photovoltaic silicon wafers, they need to be cleaned or processed by a wafer insertion machine, which transports the wafers via a feeding mechanism. High-speed, high-precision wafer insertion machines utilize technologies such as CCD image processing and analysis, and water flow separation and adsorption to effectively achieve wafer separation, transportation, defect detection, flexible alignment, and basket loading.
[0003] Traditional wafer insertion machines are widely used in the photovoltaic industry, but due to limitations in their structure and working principle, they often present some significant problems. For example, in water-jet wafer slicing, the fixed jet angle causes considerable inconvenience. Photovoltaic silicon wafers come in various sizes and thicknesses, and the fixed jet angle cannot flexibly adapt to these variations. When the wafer specifications do not match the jet angle, it can lead to poor slicing results, affecting production efficiency and product quality. Some wafer insertion machines use air flotation, generating bubbles in the slicing water tank. However, insufficient mixing uniformity between the bubbles and the jet is a prominent issue. Inadequate mixing causes uneven stress on the silicon wafers during slicing and conveying, easily leading to wafer damage or misalignment. This not only increases losses during production but may also adversely affect subsequent processing stages. Summary of the Invention

[0005] The purpose is to enable the jet angle of the inserter to be adjusted according to requirements and to ensure that the air bubbles are evenly mixed in the jet.

[0010] Furthermore, the steering unit includes a steering knob disposed inside the knob, a worm gear disposed at the end of the steering knob away from the knob, and a worm wheel disposed at the top of the auxiliary nozzle closest to the knob, the worm wheel being meshed with the worm gear.
[0011] Furthermore, a positioning block is provided at the connection between the adjustment knob and the inner wall of the knob, and a positioning hole is opened at the upper part of the knob, with the inner wall of the positioning hole rotatably connected to the positioning block.
[0012] Furthermore, the mixing mechanism includes a cover disposed near the material basket in the water tank, a waterproof motor disposed on the outer wall of the cover, a four-way pipe disposed on the side of the cover near the waterproof motor, three ports of the four-way pipe on the side away from the cover being fixedly connected to the main nozzle and two auxiliary nozzles respectively, an impeller disposed on the inner wall of the cover near the waterproof motor, a rotating shaft disposed on the side of the impeller away from the waterproof motor, a plurality of blades arranged in a linear array in the middle of the rotating shaft, a water inlet hole opened on the side of the cover away from the impeller, and an air intake unit disposed on the side of the cover away from the impeller.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0035] Example 1, referring to Figures 1-13 This invention provides a first embodiment of an anti-sucking chip inserter feeding device, comprising a chip inserter body 1, a water tank 2 fixedly connected inside the chip inserter body 1, a material basket 3 fixedly connected inside the water tank 2, a spray mechanism 4 installed at the bottom of the material basket 3, and a mixing mechanism 5 installed inside the water tank 2 near the material basket 3 for generating water flow and air bubbles; the spray mechanism 4 includes a housing 41 slidably connected to the bottom of the material basket 3, the housing 41 being able to move up and down after being driven by the moving parts of the material basket 3, and a knob 42 rotatably connected to the side of the housing 41 away from the mixing mechanism 5, the knob 42 rotating so that the connected parts will... The knob 42 rotates stepwise. A bracket 43 is fixedly connected to the side of the knob 42 near the outer casing 41. The bracket 43 rotates together with the knob 42. A main nozzle 44 is fixedly connected to the middle of the bracket 43. Support shafts 45 are symmetrically fixedly connected to both ends of the bracket 43. A secondary nozzle 46 is rotatably connected to the bottom of the support shaft 45. The top of the secondary nozzle 46 is rotatably connected to the corresponding support shaft 45. A pulley 47 is fixedly connected to the bottom of the secondary nozzle 46. A circular belt 48 is sleeved on the outside of the pulley 47. When any one pulley 47 rotates, it will cause the other pulley 47 to rotate in the opposite direction through the circular belt 48. A steering unit is assembled inside the knob 42 to adjust the angle of the secondary nozzle 46.
[0036] Specifically, the outer casing 41 can move up and down under the action of the moving parts of the basket 3. The knob 42 moves together with the outer casing 41, and the bracket 43 moves together with the knob 42. The support shaft 45 connects the bracket 43 to the corresponding auxiliary nozzle 46. The auxiliary nozzle 46 has the function of rotating up and down and rotating to both sides. The main nozzle 44 is in the center position and has the function of rotating up and down. The pulley 47 can drive the corresponding auxiliary nozzle 46 to rotate. When the auxiliary nozzle 46 is under force, it can also drive the pulley 47 to rotate synchronously. The circular belt 48 connects the two pulleys 47 and makes the two pulleys 47 rotate in opposite directions. The jetting mechanism 4 can adjust the jetting direction and angle, thereby achieving precise wafer splitting operation. This improvement enables the wafer inserter to better adapt to silicon wafers of various sizes and thicknesses, avoids damage to silicon wafers due to jetting angle problems, improves wafer splitting quality and efficiency, and increases the applicability of the equipment.
[0037] Reference Figure 6 The bottom of the support shaft 45 is provided with a limiting block, and the top of the auxiliary nozzle 46 is provided with a limiting hole. The limiting block and the limiting hole are rotatably connected.
[0038] Specifically, the limiting block constrains the auxiliary nozzle 46 through the limiting hole, so that when the auxiliary nozzle 46 rotates to both sides, it is centered on the support shaft 45.
[0039] Reference Figure 7 The outer side of the pulley 47 has a connecting groove, and the round belt 48 is twisted 180 degrees and fitted into the connecting groove of the two pulleys 47.
[0040] Specifically, pulley 47 is connected to round belt 48 through a connecting groove, and the round belt 48 can rotate synchronously in opposite directions after it is twisted.
[0041] Reference Figure 8 The steering unit includes a steering knob 49 rotatably connected to the inside of the knob 42, a worm gear 410 fixedly connected to the end of the steering knob 49 away from the knob 42, and a worm wheel 411 fixedly connected to the top of the auxiliary nozzle 46 closest to the knob 42. The worm wheel 411 is meshed with the worm gear 410.
[0042] Specifically, when the directional knob 49 is subjected to force, it can drive the worm gear 410 to rotate. While the worm gear 410 is rotating, it drives the worm wheel 411 to rotate. The worm wheel 411 drives the auxiliary nozzle 46 connected to it to rotate. The auxiliary nozzle 46 rotates in the opposite direction through the pulley 47 and the circular belt 48.
[0043] Reference Figure 8 A positioning block is provided at the connection between the adjustment knob 49 and the inner wall of the knob 42. A positioning hole is opened on the upper part of the knob 42, and the inner wall of the positioning hole is rotatably connected to the positioning block.
[0044] Specifically, the positioning block cooperates with the positioning hole to prevent the adjustment knob 49 from falling off the knob 42, and to make the adjustment knob 49 move together with the knob 42.
[0045] Example 2, refer to Figures 9-13 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the mixing mechanism 5 includes a cover 51 fixedly connected to the water tank 2 near the material basket 3, a waterproof motor 52 fixedly connected to the outer wall of the cover 51, a four-way pipe 53 fixedly connected to the side of the cover 51 near the waterproof motor 52, three ports of the four-way pipe 53 away from the cover 51 being fixedly connected to the main nozzle 44 and two auxiliary nozzles 46 respectively, an impeller 54 rotatably connected to the inner wall of the cover 51 near the waterproof motor 52, a rotating shaft 55 fixedly connected to the side of the impeller 54 away from the waterproof motor 52, several blades 56 linearly arrayed and fixedly connected to the middle of the rotating shaft 55, a water inlet hole 57 opened on the side of the cover 51 away from the impeller 54, and an air intake unit assembled on the side of the cover 51 away from the impeller 54.
[0046] Specifically, the housing 51 can accommodate moving parts. The output shaft of the waterproof motor 52 is connected to the impeller 54 and provides power to the mixing mechanism 5. The four-way pipe 53 can deliver the water flow containing air bubbles generated by the mixing mechanism 5 in segments to the main nozzle 44 and the auxiliary nozzle 46. The impeller 54 rotates under the drive of the motor and drives the water flow into the four-way pipe 53 through centrifugal force. The rotating shaft 55 can rotate with the impeller 54 and drive the blades 56 to rotate. After the blades 56 rotate, they mix the water flow and air inside the housing 51, so that the water flow is uniformly mixed with the internal air bubbles. 4. After the beam is discharged through the four-way pipe 53, a negative pressure is formed inside the cover 51. Under the action of the pressure difference, the water in the water tank 2 flows into the inside of the cover 51 through the water inlet 57. The mixing mechanism 5 can evenly mix the air and water flow. Through this process, tiny bubbles will be evenly distributed in the jet. This jet containing bubbles can weaken the adsorption force between silicon wafers, making the silicon wafers smoother during the wafer slicing and conveying process, reducing silicon wafer damage or positional displacement caused by adsorption force. The mixing mechanism 5 improves the efficiency of silicon wafer slicing and reduces losses in the production process.
[0047] Reference Figures 10-13 The intake unit includes an air pipe 58 fixedly connected to the side of the housing 51 away from the impeller 54, a plunger 59 symmetrically slidably connected to the side of the air pipe 58 near the rotating shaft 55, a connecting rod 510 on the side of the plunger 59 near the rotating shaft 55, a connecting plate 511 rotatably connected to the connecting rod 510 away from the plunger 59, a rotating arm 512 rotatably connected to the connecting plate 511 near the rotating shaft 55, the side of the rotating arm 512 away from the connecting plate 511 being fixedly connected to the rotating shaft 55, and four one-way valves 513 symmetrically fixedly connected to both sides of the air pipe 58.
[0048] Specifically, the rotating arm 512 rotates together with the rotating shaft 55 and drives the connecting plate 511 to rotate. The connecting plate 511 pushes and pulls the plunger 59 through the connecting rod 510 to make it reciprocate in the air tube 58. The reciprocating motion of the plunger 59 cooperates with the one-way valve 513 to switch between positive and negative pressure inside the air tube 58. When the air tube 58 is under negative pressure, it draws in outside air, and when it is under positive pressure, it pushes the air into the casing 51.
[0049] Reference Figure 10 The air pipe 58 is provided with a long pipe on the side away from the cover 51, and the cover 51 is provided with a partition between the impeller 54 and the blade 56.
[0050] Specifically, the top of the long tube is higher than the liquid level in the water tank 2, allowing outside air to enter the air pipe 58. The baffle separates the working areas of the impeller 54 and the blades 56. The rest of the structure is the same as that in Example 1.
[0051] Based on embodiments 1-2, the working principle of this invention is as follows: When it is necessary to tilt the nozzle angle vertically, the knob 42 is rotated. Rotating the knob 42 simultaneously rotates the bracket 43, which in turn moves the main nozzle 44 and the two support shafts 45. The support shafts 45 then move the auxiliary nozzles 46 connected to them. By rotating the knob 42 in different directions, the main nozzle 44 and auxiliary nozzles 46 can be tilted vertically. When it is necessary to tilt the auxiliary nozzles 46 to the sides, the adjustment knob is rotated. The adjustment knob, through the worm gear 411 and worm 410, causes the corresponding auxiliary nozzle 46 to rotate. The auxiliary nozzle 46, through the two pulleys 47 and the circular belt 48, causes another nozzle to rotate in the opposite direction. By rotating the adjustment knob in different directions, the lateral angle of the auxiliary nozzles 46 can be adjusted. When it is necessary to divide the water flow into sections, the waterproof motor 52 is started, causing the impeller 54 to rotate and pumping the water inside the casing 51 to four... Water flows through the four-way pipe 53 to the main nozzle 44 and the auxiliary nozzle 46. The rotating shaft 55 rotates while driving the connected blades 56 to rotate. The rotating shaft 55 also rotates the rotating arm 512. The rotating arm 512 rotates the two connecting rods 510 through the connecting plate 511. The connecting rods 510 push and pull the plunger 59 to make it reciprocate. During the reciprocating motion of the plunger 59, it cooperates with the one-way valve 513 to pump air into the inside of the casing 51. While the impeller 54 discharges the water in the casing 51 through the four-way pipe 53, the water outside the casing 51 rushes into the inside of the casing 51 through the water inlet 57 and flows to the position of the impeller 54. After the water and air enter the inside of the casing 51, they are mixed into a water flow with a large number of tiny bubbles under the impact of the blades 56. Then, the water flows through the four-way pipe 53 into the main nozzle 44 and the auxiliary nozzle 46, and finally rushes towards the silicon wafers stacked in the basket 3, causing the stacked silicon wafers to be separated under the action of the water flow.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
