Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor processing, in particular to a boat transfer mechanism and a multi-boat transfer device. Background Art

[0002] Boat transfer equipment is often used in the production and manufacturing process of solar cells, and its function is to realize the transfer of boats between multiple stations such as a conveyor line, a buffer rack, and a paddle. In order to sense whether the boat is accurately placed on the gripper of the boat transfer equipment, a plurality of induction pressing pieces are usually arranged at the positions where the gripper contacts the boat ears. The opening and closing of a microswitch are controlled through the induction data of the induction pressing pieces to ensure that the gripper performs the next action only after the boat is placed in place. However, the sensitivity of this induction method is relatively low. When there are surface damages on the boat ears or the boat is placed obliquely, the plurality of induction pressing pieces cannot be pressed down simultaneously, resulting in situations such as failure to sense or asynchronous sensing, causing misoperation of the boat transfer equipment. Moreover, the existing boat transfer equipment can usually only pick up a single boat at a time and send the single boat into a tube furnace for process processing, and the transfer efficiency of the boat transfer equipment is relatively low. Summary of the Utility Model

[0003] The first object of the utility model is to provide a boat transfer mechanism, which is used to solve the problems that the existing boat transfer equipment has insufficient detection sensitivity for the boat placed in place, is prone to equipment misoperation, and can only pick up a single boat at a time and has a relatively low transfer efficiency.

[0004] Another object of the utility model is to provide a multi-boat transfer device, and the boat transfer mechanism thereof can solve the problems that the existing boat transfer equipment has insufficient detection sensitivity for the boat placed in place, is prone to equipment misoperation, and can only pick up a single boat at a time and has a relatively low transfer efficiency.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] In the first aspect, a boat transfer mechanism is provided, which is arranged between two transfer grippers. The boat transfer mechanism includes:

The first pawl body and the second pawl body are respectively used to lift the workpieces on both sides of the bracket assembly, so that the first trigger portion and the second trigger portion respectively rotate around the rotating shaft and respectively abut and trigger the first trigger member and the second trigger member.

[0013] Both ends of the second pawl body respectively extend and protrude toward the first pawl body to form two second rotating members. The second mounting hole is formed in the second rotating member, and the second trigger portion is connected to the second rotating member. The two second rotating members form a surrounding frame structure and surround both sides of the first rotating member, so that the first mounting hole and the second mounting hole are coaxially arranged.

[0014] In one embodiment, the pawl assembly further includes a first reset elastic member and a second reset elastic member. The first reset elastic member is used to apply an elastic force to the first pawl to keep the first trigger portion away from the first trigger member; the second reset elastic member is used to apply an elastic force to the second pawl to keep the second trigger portion away from the second trigger member.

[0015] In one embodiment, under the elastic force applied by the first reset elastic member, the first pawl is disposed at an angle with the horizontal plane where the rotating shaft is located, and the other side of the first pawl body away from the rotating shaft extends obliquely upward toward the horizontal plane; and / or,

[0022] Advantages of the present utility model:

[0023] The boat handling mechanism provided by the present utility model has a bracket assembly including a bracket body, a rotating shaft, a first trigger member, and a second trigger member disposed on the bracket body. The pawl assembly includes a first pawl and a second pawl. The first pawl includes a first pawl body and a first trigger portion connected to each other. The second pawl includes a second pawl body and a second trigger portion connected to each other. The first pawl and the second pawl are respectively rotatably connected to the rotating shaft. Along the length direction of the rotating shaft, the first trigger portion and the second trigger portion are staggered, so that the first pawl body and the second pawl body are disposed on both sides of the rotating shaft. The first pawl body and the corresponding handling pawl can handle a single boat, and the second pawl body and the corresponding handling pawl can handle a single boat, thereby realizing workpiece handling on both sides of the bracket assembly at the same time. By handling two boats simultaneously, the handling efficiency is greatly improved. Moreover, since the first trigger portion and the second trigger portion are rotatably connected to the rotating shaft, when the first pawl body and the second pawl body are pressed when handling the boat, the first trigger portion and the second trigger portion rotate, and the first trigger portion and the second trigger portion rotate in opposite directions around the rotating shaft and respectively abut against and trigger the first trigger member and the second trigger member. After the first trigger member and the second trigger member are triggered, the multi-boat handling device will perform the next action. The first pawl body and the first trigger portion form a seesaw structure relative to the rotating shaft. Similarly, the second pawl body and the second trigger portion also form a seesaw structure relative to the rotating shaft. This seesaw structure improves the sensitivity of the pawl assembly to the workpiece, is not affected by adverse conditions such as damage to the surface of the boat and the inclination of the boat placement, and greatly reduces the risk of malfunction of the boat handling mechanism.

[0024] The multi-boat handling device provided by the present utility model has the above-mentioned boat handling mechanism. The multi-boat handling device further includes two relatively disposed handling pawls. The boat handling mechanism is disposed between the two handling pawls. The first pawl and the second pawl of the boat handling mechanism respectively face the two handling pawls to handle two workpieces at the same time. By handling two boats simultaneously, the handling efficiency of the multi-boat handling device is greatly improved. Moreover, the first pawl body and the first trigger portion of the boat handling mechanism form a seesaw structure relative to the rotating shaft, and the second pawl body and the second trigger portion also form a seesaw structure relative to the rotating shaft. The seesaw structure improves the sensitivity of the pawl assembly to the workpiece, is not affected by adverse conditions such as damage to the surface of the boat and the inclination of the boat placement, reduces the risk of malfunction of the boat handling mechanism, and improves the working reliability of the multi-boat handling device.

[0034] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] As Figure 1 and Figure 2 shown, this embodiment first provides a boat transfer mechanism, and the boat transfer mechanism is arranged between two handling claws 100 (refer to Figure 5 ). The boat transfer mechanism and the two handling claws 100 can achieve single-time double-boat transfer. The following workpieces include but are not limited to boats, and can also be other electronic components that need to be transferred between different workstations.

[0039] The boat transfer mechanism includes a bracket assembly 1 and a claw assembly 2. The bracket assembly 1 includes a bracket body 11 and a rotating shaft 12, a first trigger 13 and a second trigger 14 arranged on the bracket body 11. The claw assembly 2 includes a first claw 21 and a second claw 22. The first claw 21 includes a first claw body 211 and a first trigger portion 212 connected to each other. The second claw 22 includes a second claw body 221 and a second trigger portion 222 connected to each other. The first claw 21 and the second claw 22 are respectively rotatably connected to the rotating shaft 12. Along the length direction of the rotating shaft 12, the first trigger portion 212 and the second trigger portion 222 are staggered, so that the first claw body 211 and the second claw body 221 are arranged on both sides of the rotating shaft 12. The first claw body 211 and the corresponding handling claw 100 can handle a single boat, and the second claw body 221 and the corresponding handling claw 100 can handle a single boat, thereby realizing workpiece handling on both sides of the bracket assembly 1 at the same time, and greatly improving the handling efficiency through double-boat handling at the same time.

[0040] Since the first pawl 21 and the second pawl 22 are rotatably connected to the rotating shaft 12, when the first pawl body 211 and the second pawl body 221 carry the boat, they are pressed, causing the first trigger portion 212 and the second trigger portion 222 to rotate. The first trigger portion 212 and the second trigger portion 222 rotate in opposite directions around the rotating shaft 12 respectively, and respectively abut and trigger the first trigger member 13 and the second trigger member 14. After the first trigger member 13 and the second trigger member 14 are triggered, the multi-boat handling device will perform the next action. The first pawl body 211 and the first trigger portion 212 form a seesaw structure relative to the rotating shaft 12. Similarly, the second pawl body 221 and the second trigger portion 222 also form a seesaw structure relative to the rotating shaft 12. This seesaw structure improves the sensing sensitivity of the pawl assembly 2 to the workpiece, is not affected by adverse conditions such as damage to the surface of the boat and the inclination of the boat placement, and greatly reduces the risk of misoperation of the boat handling mechanism.

[0041] The first trigger member 13 and the second trigger member 14 include but are not limited to microswitches, and can also be electromagnetic switches, etc. This embodiment does not make specific limitations.

[0042] In order to achieve the staggered arrangement and simultaneous rotation of the first trigger portion 212 and the second trigger portion 222 on the rotating shaft 12, a first mounting hole is provided on the first pawl body 211, and a second mounting hole is provided on the second pawl body 221. The first mounting hole and the second mounting hole are coaxially arranged, and the rotating shaft 12 is rotatably inserted into the first mounting hole and the second mounting hole.

[0043] As Figure 3 shown, in one embodiment, the first trigger portion 212 includes first trigger pins perpendicular to the first pawl body 211 and spaced apart. The first trigger pins are used to abut the first trigger member 13. The second trigger portion 222 includes second trigger pins perpendicular to the second pawl body 221 and spaced apart. The second trigger pins are used to abut the second trigger member 14. The perpendicular arrangement of the first trigger pins and the second trigger pins can reduce the thickness dimension of the boat handling mechanism in the direction perpendicular to the rotating shaft 12, the structure is relatively compact, and the influence on the length of the boat that can be handled is reduced.

[0044] In order to improve the sensing trigger accuracy, the first trigger portion 212 is provided with two first trigger pins, and the two first trigger pins are spaced apart at both ends of the first pawl body 211. Correspondingly, the first trigger member 13 is also correspondingly provided with two. The second trigger portion 222 is also provided with two second trigger pins, and the two second trigger pins are respectively located at both ends of the second pawl body 221. Correspondingly, the second trigger member 14 is also correspondingly provided with two.

[0045] The middle part of the first pawl body 211 extends and protrudes towards the second pawl body 221 to form a first rotating member 2111. The first mounting hole is formed on the first rotating member 2111, and the first triggering portion 212 is connected to the first rotating member 2111, so that the first triggering portion 212 and the first pawl body 211 form a seesaw structure relative to the rotating shaft 12.

[0046] Similarly, both ends of the second pawl body 221 extend and protrude towards the first pawl body 211 to form second rotating members 2211. The second mounting holes are formed in the second rotating members 2211, and the second triggering portions 222 are connected to the second rotating members 2211, so that the second triggering portions 222 and the second pawl body 221 form a seesaw structure relative to the rotating shaft 12. The two second rotating members 2211 form a surrounding frame structure and surround both sides of the first rotating member 2111, so that the first mounting hole and the second mounting hole are coaxially arranged, realizing the side-by-side arrangement of the first pawl body 211 and the second pawl body 221 on both sides of the rotating shaft 12.

[0047] In order to realize the reset of the pawl assembly 2 after carrying the boat, the pawl assembly 2 further includes a first reset elastic member 23 and a second reset elastic member 24. The first reset elastic member 23 is used to apply an elastic force to the first pawl 21 to move the first triggering portion 212 away from the first triggering member 13. The second reset elastic member 24 is used to apply an elastic force to the second pawl 22 to move the second triggering portion 222 away from the second triggering member 14. When the workpiece detaches from the first pawl body 211 or the second pawl body 221, the elastic force can cause the first pawl 21 or the second pawl 22 to rotate to restore the initial state, preparing for the next carrying.

[0048] Specifically, in one embodiment, the first reset elastic member 23 and the second reset elastic member 24 can adopt compression springs. The two compression springs are respectively sleeved on the first triggering pin and the second triggering pin, and one end is connected to the first rotating member 2111 or the second rotating member 2211. The first triggering pin and the second triggering pin can provide guidance for the compression springs. The compression spring of the first reset elastic member 23 is arranged between the first pawl 21 and the first triggering member 13, and the compression spring of the second reset elastic member 24 is arranged between the second pawl 22 and the second triggering member 14.

[0049] In the initial state when the first reset elastic member 23 applies an elastic force, the first pawl 21 is arranged at an angle with the horizontal plane where the rotating shaft 12 is located, and the other side of the first pawl body 211 away from the rotating shaft 12 extends obliquely upward towards the upper part of the horizontal plane. In this way, when the first pawl 21 carries the boat, the first pawl body 211 can be rotated under pressure to form a horizontal state, avoiding the risk of the boat slipping from the first pawl body 211 during carrying.

[0050] Similarly, in the initial state where the second reset elastic member 24 exerts an elastic force, the second pawl 22 is disposed at an angle with the horizontal plane where the rotating shaft 12 is located, and the other side of the second pawl body 221 away from the rotating shaft 12 extends obliquely upward toward the upper side of the horizontal plane. In this way, when the second pawl 22 transports the boat, the second pawl body 221 can be rotated under pressure to form a horizontal state, avoiding the risk of the boat slipping from the second pawl body 221 during transportation.

[0051] Since the reset action of the pawl assembly 2 is driven by the elastic forces of the first reset elastic member 23 and the second reset elastic member 24, the magnitude of the elastic force is not easy to control, making it difficult for the pawl assembly 2 to accurately reset to the initial state. Therefore, the pawl assembly 2 further includes a limiting mechanism 25. When the first reset elastic member 23 drives the first pawl 21 to rotate and the second reset elastic member 24 drives the second pawl 22 to rotate, the limiting mechanism 25 can abut and stop the first pawl 21 and the second pawl 22 to keep the first pawl 21 and the second pawl 22 in the initial state.

[0052] Specifically, the limiting mechanism 25 includes a limiting block 251 mounted on the first pawl 21 and the second pawl 22, and a limiting pin 252 mounted on the bracket body 11. The limiting pin 252 is located above the limiting block 251. In the initial state, the limiting block 251 abuts against the limiting pin 252 to prevent the first pawl 21 and the second pawl 22 from rotating too much during resetting and exceeding the inclination angle of the initial state. When the first pawl body 211 and the second pawl body 221 lift the workpiece, the limiting block 251 moves away from the limiting pin 252, and the limiting mechanism 25 will not affect the transportation action of the boat transporting mechanism.

[0053] When transporting boats of different model sizes, due to their different weights, the required inclination angles of the first pawl body 211 and the second pawl body 221 in the initial state are different. Therefore, the limiting mechanism 25 further includes an adjusting seat 253 mounted on the bracket body 11. The adjusting seat 253 is provided with a threaded hole, and the limiting pin 252 is threadedly connected to the threaded hole. The limiting pin 252 can adjust the distance between the limiting block 251 and the adjusting seat 253 to adjust the included angle between the first pawl 21 and / or the second pawl 22 and the horizontal plane.

[0054] In an embodiment, the bracket body 11 is provided with a first installation groove 111 and a second installation groove 112, as Figure 2 and Figure 4 shown, the first installation groove 111 and the second installation groove 112 are staggered on both sides of the rotating shaft 12, the first trigger member 13 is disposed in the first installation groove 111, and the second trigger member 14 is disposed in the second installation groove 112.

[0055] When the openings of the first installation groove 111 and the second installation groove 112 face the corresponding handling claws 100 on both sides, a guiding hole communicating with the first installation groove 111 or the second installation groove 112 is further formed on the bracket body 11. The first trigger pin and the second trigger pin are slidably inserted into the guiding hole so as to abut against the first trigger member 13 or the second trigger member 14.

[0056] To increase cleanliness, covers 15 that can be detachably connected are provided on both sides of the bracket body 11, which can shield the first installation groove 111 and the second installation groove 112 to prevent dust and other impurities from affecting the working accuracy of the first trigger member 13 and the second trigger member 14.

[0057] This embodiment also provides a multi-boat handling device, as Figure 5 shown. The multi-boat handling device has the above-mentioned boat handling mechanism. The multi-boat handling device further includes two relatively arranged handling claws 100. The boat handling mechanism is arranged between the two handling claws 100. The first claw 21 and the second claw 22 of the boat handling mechanism face the two handling claws 100 respectively to handle two workpieces simultaneously. The handling efficiency of the multi-boat handling device is greatly improved by handling two boats at the same time. Moreover, the first claw body 211 and the first trigger portion 212 of the boat handling mechanism form a seesaw structure relative to the rotating shaft 12, and the second claw body 221 and the second trigger portion 222 of the second claw also form a seesaw structure relative to the rotating shaft 12. The seesaw structure improves the sensing sensitivity of the claw assembly 2 to the workpiece, is not affected by adverse conditions such as damage to the surface of the boat and the inclination of the boat placement, reduces the risk of misoperation of the boat handling mechanism, and improves the working reliability of the multi-boat handling device.

[0058] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
