DETAILED DESCRIPTION

[0027] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it. The embodiments are not intended to limit the present application.

[0028] Reference Figure 1The application discloses a rotating fixing device for fixing and rotating a product to be welded, which comprises a jacking fixing mechanism 10, a pressing mechanism 20 and a rotating mechanism 30. The jacking fixing mechanism 10 comprises a first lifting part 11 and a rotating fixing part 12, the rotating fixing part 12 is connected with the first lifting part 11 and can rotate, a clamping groove 141 is formed in the outer wall of the rotating fixing part 12, and the rotating fixing part 12 is used for fixing the product to be welded. The pressing mechanism 20 comprises a second lifting part 21 and a rotating pressing head 22, the rotating pressing head 22 is connected with the second lifting part 21 and can rotate, and the rotating pressing head 22 is used for fixing the product to be welded in cooperation with the rotating fixing part 12. The rotating mechanism 30 comprises a rotating seat 31, the rotating seat 31 is arranged in the air along the axial direction, a first clamping part 311 matched with the clamping groove 141 is arranged on the cavity wall of the rotating seat 31, the rotating seat 31 comprises a first state and a second state, when the rotating seat 31 is in the first state, the rotating seat 31 stops rotating, and the rotating fixing part 12 and the rotating pressing head 22 are away from the rotating seat 31, when the rotating seat 31 is in the second state, the rotating seat 31 rotates, before the rotating seat 31 rotates, the first lifting part 11 rises, drives the rotating fixing part 12 and the product to be welded to stretch out from the rotating seat 31, the first clamping part 311 is clamped with the clamping groove 141, and the pressing mechanism 20 descends, so that the rotating pressing head 22 abuts against the product to be welded.

[0029] Reference Figure 2As shown, the jacking fixing mechanism 10 is used to realize the lifting and fixing of the product to be welded. Specifically, the jacking fixing mechanism 10 comprises a first lifting component 11 and a rotating fixing component 12. The rotating fixing component 12 is used to fix the product to be welded and rotate the product to be welded in cooperation with the rotating mechanism 30; the first lifting component 11 is used to realize the lifting of the rotating fixing component 12 and the product to be welded, so as to realize the fixing and rotation of the product to be welded in cooperation with the rotating mechanism 30 and the pressing mechanism 20. Preferably, the first lifting component 11 is arranged as a pneumatic cylinder. The clamping groove 141 on the outer wall of the rotating fixing component 12 can well cooperate with the first clamping piece 311 of the rotating seat 31, so as to ensure that the rotating fixing component 12 and the rotating seat 31 can rotate synchronously and ensure the product quality; at the same time, the quick positioning of the two can also be effectively realized, and the production efficiency is improved. Before the rotating fixing device described in the present application is developed, the product to be welded has also been welded by other ways. For example, after the camera body and the lens are fixed, the welding cavity is rotated around the circumference of the product once to realize welding. The equipment used in this welding way is large in size and low in space utilization. The rotating fixing device described in the present application adopts the welding device to be fixed and the product to be welded to be rotated, which greatly reduces the size of the whole equipment and improves the space utilization. Figure 6 As shown, the pressing mechanism 20 is used to press the product to be welded, so as to ensure that no shaking and other problems occur in the welding process, the fixing effect is good, and the yield of the product is ensured. Specifically, the pressing mechanism 20 comprises a second lifting component 21 and a rotating pressing head 22. The rotating pressing head 22 is used to fix the product to be welded in cooperation with the rotating fixing component 12. The second lifting component 21 is used to realize the lifting of the rotating pressing head 22, so that the rotating pressing head 22 abuts or moves away from the product to be welded. Preferably, the second lifting component 21 is arranged as a pneumatic slide. Figure 7The rotating mechanism 30 is used to drive the rotating fixed part 12 and the rotating pressure head 22 to rotate synchronously. Specifically, the rotating mechanism 30 comprises a rotating seat 31 which is arranged in the axial space so that the rotating fixed part 12 and the product to be welded can pass out of the space of the rotating seat 31. The first clamping part 311 can be well matched with the clamping groove 141, so that the rotating fixed part 12 and the rotating seat 31 can rotate synchronously, and the product quality is ensured. Preferably, the first clamping part 311 is arranged as a wedge-shaped block, so that it is easier to match with the clamping groove 141, and it is easier to align and improve the production efficiency. The rotating mechanism 30 further comprises a rotating driving part 314 which is used to drive the rotating seat 31 to rotate. Preferably, the rotating driving part 314 is arranged as a motor, a gear or a belt transmission structure. The rotating seat 31 comprises a first state and a second state. The first state is a stop state, and when the rotating seat 31 is in the first state, the rotating seat 31 stops rotating, and the rotating fixed part 12 and the rotating pressure head 22 are away from the rotating seat 31. The second state is a working state, and the rotating seat 31 rotates to drive the rotating fixed part 12, the rotating pressure head 22 and the product to be welded to rotate synchronously, so as to cooperate with the welding device to perform welding. Before the rotating seat 31 rotates, the first lifting part 11 rises to drive the rotating fixed part 12 and the product to be welded to extend out of the rotating seat 31, and the first clamping part 311 is clamped with the clamping groove 141. The pressing mechanism 20 is lowered, so that the rotating pressure head 22 abuts against the product to be welded. The rotating fixing device has the advantages of high space utilization, high automation degree, good fixing effect, high production efficiency and high product yield.

[0030] Referring to Figure 3 In some embodiments, the rotating fixed part 12 comprises a first support 121, a rotating shaft 13 and an abutting table 14. The first support 121 is connected with the first lifting part 11, and the rotating shaft 13 is arranged on the first support 121. The first support 121 serves as an intermediate part and plays a role of receiving the abutting table 14 and the rotating shaft 13. The abutting table 14 is rotatably connected with the rotating shaft 13. Preferably, a bearing is arranged between the rotating shaft 13 and the abutting table 14, and the two are rotatably connected through the bearing. The abutting table 14 is internally provided with a clamping jaw structure 142 which is used to fix the product to be welded. By arranging the clamping jaw structure 142, the product to be welded which is composed of two parts can be effectively fixed.

[0031] Referring to Figure 4As shown, the rotating fixing device provided by the present application, in some embodiments, the claw structure 142 is arranged along the height direction of the abutting table 14. The arrangement of the direction is to ensure that the claw structure 142 can effectively clamp and fix the product to be welded. The claw structure 142 includes a claw 1421, a first pushing member 1422, a first abutting spring 1423 and a first rotating shaft 1424. The claw 1421 is used to lock the product to be welded composed of two parts; the first pushing member 1422 is used to cooperate with the first tripping member 312 to realize the unlocking of the claw 1421; the first abutting spring 1423 is used to abut the claw 1421 to realize the locking of the product to be welded; and the first rotating shaft 1424 is used to cooperate with the claw 1421 to form a lever structure, effectively locking and fixing the product to be welded. Specifically, the claw 1421 is rotatably connected to the abutting table 14 through the first rotating shaft 1424; the first pushing member 1422 is connected to the claw 1421, and the first pushing member 1422 is located on the side of the first rotating shaft 1424 away from the first lifting member 11, and the first tripping member 312 adapted to the first pushing member 1422 is arranged on the rotating seat 31; the two ends of the first abutting spring 1423 abut the claw 1421 and the abutting table 14 respectively, and the first abutting spring 1423 is located between the first pushing member 1422 and the first rotating shaft 1424. The first abutting spring 1423 includes a first abutting state and a second abutting state. When the first abutting spring 1423 is in the first abutting state, the first tripping member 312 is separated from the first pushing member 1422, and the first abutting spring 1423 abuts the claw 1421, so that the claw 1421 fixes the product to be welded; when the first abutting spring 1423 is in the second abutting state, the first tripping member 312 abuts the first pushing member 1422, the claw 1421 rotates along the first pushing member 1422 and compresses the first abutting spring 1423, so that the claw 1421 releases the product to be welded. Considering that the product to be welded needs to be fixed and assembled before the welding process, therefore, the claw structure 142 is arranged to lock and fix the product to be welded. However, considering that the welding device needs to weld the entire circumferential direction of the product to be welded during the welding process, the existence of the claw structure 142 will undoubtedly hinder the welding of the welding device. Therefore, the rotating fixing device provided by the present application is designed by using the principle of lever. Before welding, the first abutting spring 1423 abuts the claw 1421, so that the claw 1421 fixes the product to be welded, ensuring that the product to be welded will not shake, fall off and the like. When welding, the first tripping member 312 on the rotating seat 31 can abut the first pushing member 1422, so that the claw 1421 rotates around the first rotating shaft 1424 and separates from the product to be welded, so as not to affect the welding of the welding device; due to the existence of the abutting table 14 and the rotating pressure head 22, after the claw 1421 is separated, the product to be welded can still be well fixed, ensuring the welding effect and guaranteeing the product yield.Meanwhile, when the welding is completed and the abutting table 14 and the rotating seat 31 are separated, the clamping jaw 1421 can still be subjected to the force of the first abutting spring 1423, so that the fixing of the product after welding is achieved, and the functionality is strong, the degree of automation is high, and the fixing effect is good. Preferably, the surface of the first tripping piece 312 in contact with the first pushing piece 1422 is provided with an inclined surface, which is inclined away from the product to be welded. The design of the structure can effectively make the first pushing piece 1422 slide along the inclined surface, so as to achieve the separation of the clamping jaw 1421 and the product to be welded.

[0032] In some embodiments, the rotating fixing device is characterized in that the abutting table 14 is provided with a sliding groove 1425 in the height direction of the abutting table 14, a sliding block 1426 is movably arranged in the sliding groove 1425, and the clamping jaw structure 142 is arranged in the sliding block 1426. The sliding groove 1425 is further provided with a second abutting spring 1427, and the two ends of the second abutting spring 1427 abut the groove wall of the sliding groove 1425 and the sliding block 1426, respectively. When the first abutting spring 1423 is in the first abutting state, the second abutting spring 1427 abuts the sliding block 1426, so that the clamping jaw structure 142 protrudes out of the abutting table 14. When the first abutting spring 1423 is in the second abutting state, the first tripping piece 312 abuts the first pushing piece 1422, the sliding block 1426 compresses the second abutting spring 1427, and the clamping jaw structure 142 is retracted into the abutting table 14. If the clamping jaw structure 142 only relies on the lever structure to achieve the separation from the product to be welded, the clamping jaw structure 142 will need a larger radial space to accommodate the rotated clamping jaw 1421. Therefore, in order to improve the space utilization of the whole device, the sliding groove 1425 and the sliding block 1426 are arranged to realize the expansion and contraction of the clamping jaw structure 142. Before welding, the second abutting spring 1427 abuts the sliding block 1426, so that the clamping jaw structure 142 protrudes out of the abutting table 14 and locks the product to be welded, so as to ensure that the product to be welded does not shake, fall off or the like. When welding, the first tripping piece 312 abuts the first pushing piece 1422, so that the clamping jaw 1421 rotates around the first rotating shaft 1424 while exerting a force on the sliding block 1426 where the clamping jaw structure 142 is located in the height direction of the abutting table 14, so that the sliding block 1426 slides down along the sliding groove 1425 and is sunk into the abutting table 14. Meanwhile, when the welding is completed and the abutting table 14 and the rotating seat 31 are separated, the second abutting spring 1427 can still provide a force to the sliding block 1426, so that the sliding block 1426 rises along the sliding groove 1425, so that the clamping jaw 1421 is fixed and locked to the product after welding, and the functionality is strong, the degree of automation is high, and the fixing effect is good.

[0033] Referring to Figure 5As shown, the rotating fixing device provided by the application, in some embodiments, the rotating mechanism 30 further comprises a second support 32, the rotating seat 31 is rotatably arranged on the second support 32, and the second support 32 is provided with a second tripping piece 321. The first support 121 is provided with a limiting structure 122 matched with the second tripping piece 321, and the limiting structure 122 comprises a connecting rod 1221, a second rotating shaft 1222, a second pushing piece 1223, a limiting rod 1224 and a third abutting spring 1225. One end of the connecting rod 1221 is provided with the second rotating shaft 1222, and the connecting rod 1221 is rotatably arranged on the second support 32 through the second rotating shaft 1222. The limiting rod 1224 is rotatably arranged at the other end of the connecting rod 1221, and the two ends of the third abutting spring 1225 abut against the limiting rod 1224 and the first support 121 respectively, and the abutting table 14 is provided with a limiting hole 144 matched with the limiting rod 1224. The second pushing piece 1223 is rotatably connected with the connecting rod 1221, and the second pushing piece 1223 is located between the second rotating shaft 1222 and the limiting rod 1224. The second pushing piece 1223 comprises a non-working state and a working state, when the second pushing piece 1223 is in the non-working state, the third abutting spring 1225 abuts against the limiting rod 1224, the limiting rod 1224 is inserted into the limiting hole 144, and the rotation of the abutting table 14 is limited; when the second pushing piece 1223 is in the working state, the second tripping piece 321 abuts against the second pushing piece 1223, the second pushing piece 1223 drives the connecting rod 1221 to rotate, so that the limiting rod 1224 exits the limiting hole 144. Considering that before welding, relative rotation can occur between the abutting table 14 and the rotating shaft 13, which affects the alignment of the clamping groove 141 of the abutting table 14 and the first clamping piece 311, and the first tripping piece 312 and the first pushing piece 1422, resulting in the production efficiency being affected. Therefore, the limiting structure 122 is arranged to limit the rotation of the abutting table 14 before contacting the rotating seat 31. According to the lever principle, before welding, the third abutting spring 1225 abuts against the limiting rod 1224, so that the limiting rod 1224 is inserted into the limiting hole 144, and the rotation of the abutting table 14 is limited. When welding, the abutting table 14 contacts the rotating seat 31 and the second support 32 where the rotating seat 31 is located, the second tripping piece 321 abuts against the pushing rod, so that the pushing rod abuts against the connecting rod 1221, the connecting rod 1221 rotates, so that the limiting rod 1224 exits from the limiting hole 144, so that the abutting table 14 can rotate freely. The structure is small in size and can effectively limit the rotation of the abutting table 14. At the same time, the degree of automation is high.

[0034] Referring to Figure 7As shown, the rotating fixing device of the present application, in some embodiments, the second support 32 is provided with a sensor 322 for detecting the angle of the rotating seat 31, the sensor 322 is arranged, effectively ensure the position of the rotating seat 31 before welding, avoid the card slot 141 and the first clamping piece 311, and the first trip piece 312 and the first pusher 1422 can not be effectively aligned. Preferably, the sensor 322 is arranged as a fork grating, and the rotating seat 31 is provided with a channel for the detection light of the fork grating. The arrangement of the structure effectively ensures the occurrence of errors in production, guarantees the production efficiency and the yield of the product, and has high automation. In some other embodiments, sensors such as displacement sensors can also be arranged on the first lifting component 11 and the second lifting component 21, or other parts, to further ensure the yield of the product.

[0035] Referring to Figure 3 and Figure 8 As shown, the rotating fixing device of the present application, in some embodiments, the first support 121 is provided with a first height limiting rod 123, and the second support 32 is provided with a first height limiting rod 123 for abutting against the first height limiting rod 123. By arranging two height limiting rods, the damage caused by the collision between the abutting table 14 and the rotating seat 31 is effectively avoided, and the service life of the device is prolonged.

[0036] Referring to Figure 2 As shown, the rotating fixing device of the present application, in some embodiments, the first support 121 can be detachably connected with the first lifting component 11. Specifically, the first support 121 is provided with a buckle 124, and the first lifting component 11 is provided with a clamping block 111 matched with the buckle 124. When welding is needed, the buckle 124 and the clamping block 111 are clamped, and the first support 121 and the first lifting component 11 are connected. After welding is completed, the buckle 124 and the clamping block 111 are separated, so that another product to be welded can be welded by replacing the rotating fixing component 12, which has high production efficiency and high automation.

[0037] Referring to Figure 6 As shown, the rotating fixing device of the present application, in some embodiments, the surface of the rotating pressure head 22 in contact with the product to be welded is provided with a flexible pad 221. The arrangement of the flexible pad 221 effectively ensures the quality of the product and avoids problems such as crushing and embossing of the surface of the product. Preferably, the abutting table 14 is provided with a first clamping step 1428, and the rotating seat 31 is provided with a second clamping step 313 matched with the first clamping step 1428. The two are clamped to further ensure the coaxiality and thus the yield of the product. Preferably, the second clamping step 313 is also provided with a flexible pad 221 to ensure the service life of the abutting table 14.

In this process, the first tripping piece 312 abuts against the first driving piece 1422, the claw 1421 rotates along the first driving piece 1422 and compresses the first abutting spring 1423, so that the claw 1421 releases the product to be welded; the sliding block 1426 where the claw structure 142 is located slides downward along the sliding groove 1425 and is sunk into the abutting table 14; the second tripping piece 321 abuts against the second driving piece 1223, so that the connecting rod 1221 rotates and drives the limiting rod 1224 to exit from the limiting hole 144. Then, the rotary driving component 314 drives the rotary seat 31 to rotate, drives the abutting table 14, the rotary pressing head 22 and the product to be welded to rotate together, and the welding device synchronously welds the product to be welded. After the welding is completed, the first lifting component 11 is lowered to drive the rotary fixing component 12 and the product after welding to descend, and the first tripping piece 312 and the first driving piece 1422 are separated. The first abutting spring 1423, the second abutting spring 1427 and the third spring are restored again and abut against the claw 1421, the sliding block 1426 and the connecting rod 1221 respectively, so as to fix the product after welding. The rotary fixing device described in the application realizes the process originally realized manually by cooperation of three mechanisms, has high space utilization, high automation degree, good fixing effect, high production efficiency and high product yield.
