In the traditional electronics manufacturing industry, more and more electronic components are being optimized using ultrasonic welding technology to improve manufacturing processes.

Detailed Implementation

[0039] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figures 1 to 15 As shown, the present invention provides a dual-head ultrasonic wire welding machine, in one embodiment including...

[0041] Feeding and conveying device 1;

[0042] A feeding device 4 is arranged at one end of the feeding and conveying device 1. The feeding device 4 is at least used to feed the product to be welded onto the feeding and conveying device 1.

[0043] Welding device 2, which includes a wire supply mechanism (not shown in the figure), a product welding mechanism and a vision positioning mechanism 29 arranged above the feeding and conveying device 1;

[0044] The feeding and conveying device 1 is at least used to convey the product to be welded to the bottom of the product welding mechanism and press and fix it; the visual positioning mechanism 29 is at least used to position the product to be welded; the wire supply mechanism is at least used to feed the metal wire for welding into the product welding mechanism; the product welding mechanism is at least used to weld the product.

[0045] Continue to refer to Figures 1 to 15 As shown, this embodiment also includes a frame 3. The feeding and conveying device 1, the feeding device 4, and the welding device 2 are all mounted on the frame 3. Two sets of welding devices 2 and feeding devices 4 are provided, with each feeding device 4 positioned close to a welding device 2. One feeding device 4 supplies the product to be welded to the feeding and conveying device 1, while the other feeding device 4 unloads the welded product (the unloading process of this feeding device 4 is the reverse of the feeding process of the other feeding device 4; only the feeding process of the feeding device 4 will be described below). Two sets of welding devices... Both are arranged above the feeding and conveying device 1, and can weld the products on the feeding and conveying device 1 independently without interfering with each other, which can improve welding efficiency. During operation, firstly, the feeding device 4 feeds the product to be welded onto the feeding and conveying device 1. Then, the feeding and conveying device 1 conveys the product to the bottom of the product welding mechanism. Subsequently, the vision positioning mechanism 29 positions the product to be welded, and the product welding mechanism welds the product. After welding is completed, the feeding and conveying device 1 conveys the welded product to another feeding device 4 to complete the unloading.

[0046] In one embodiment, the feeding device 4 includes a hopper frame 41, a feeding and pushing mechanism 44, and a feeding clamping mechanism 45. The hopper frame 41 is arranged near one end of the feeding and conveying device 1, and a feeding conveying mechanism 42 is installed on the hopper frame 41. A material box baffle 43 is also movably arranged on the hopper frame 41. The feeding and pushing mechanism 44 is installed on one side of the material box baffle 43, and the feeding and pushing mechanism 44 is also driven to connect a feeding push rod 441. A first material passage hole 431 is opened on the material box baffle 43 at a position corresponding to the feeding push rod 441. The hopper frame 41 is located near the feeding and conveying device 1. A second material passage hole 411 is also provided on one side of the conveying device, corresponding to the first material passage hole 431; the feeding clamping mechanism 45 is arranged at one end near the material bin frame 41, and the feeding clamping mechanism 45 is at least used to clamp the material box carrying the product conveyed by the feeding conveying mechanism 42, and transfer the material box to the first material passage hole 431; the feeding push mechanism 44 is at least used to drive the feeding push rod 441 to move, so that one end of the feeding push rod 441 passes through the first material passage hole 431 and inserts into the material box, and pushes the product in the material box outward from the second material passage hole 411 onto the feeding conveying device.

[0047] In this embodiment, a feeding support frame connected to the frame 3 is also included. The hopper frame 41 and the feeding clamping mechanism 45 are both installed on the feeding support frame. The hopper frame 41 includes a hopper bottom plate, a hopper top plate, and two hopper side plates. The feeding conveying mechanism 42 is installed on the hopper bottom plate, and the hopper baffle 43 is movably arranged on the hopper bottom plate and located between the two hopper side plates. The upper part of the hopper baffle 43 has a through hole, through which the hopper top plate passes. The hopper baffle 43 can be moved left and right to adjust the distance between the hopper baffle 43 and the hopper side plates so that the feeding conveying mechanism 42 can adapt to the conveying of hoppers of different specifications and sizes. The hopper bottom plate is provided with several locking holes at intervals, and the hopper baffle 43 is provided with locking bolts. After adjusting the position of the hopper baffle 43, the locking bolts can be inserted into the locking holes to lock it, which is simple and convenient.

[0048] During operation, firstly, the position of the material box baffle 43 is adjusted left and right according to the specifications and dimensions of the material box. After adjusting to the appropriate position, it is locked and fixed with locking bolts. Then, the operator manually or an external robotic arm automatically places the material box containing the product onto the feeding conveyor mechanism 42, which conveys the material box to the feeding clamping mechanism 45. Subsequently, the feeding clamping mechanism 45 clamps the material box and moves it to the first material passage hole 431 and the second material passage hole 411 (both ends of the material box have openings, aligning the openings at both ends with the first material passage hole 431 and the second material passage hole 411, respectively). Then, the feeding pusher mechanism 44 drives the feeding pusher rod 441 to move, so that one end of the feeding pusher rod 441 passes through the first material passage hole 431 and inserts into the material box, and continues to push forward. The product in the material box is pushed outward from the second material passage 411 onto the feeding conveyor 1 (the other feeding mechanism does not have a feeding pusher 44. After the product welding is completed, the feeding pusher can continue to push the product forward to push it into the empty material box of the feeding mechanism to complete the unloading). After the product in the material box is completely pushed onto the feeding conveyor, the feeding clamping mechanism 45 clamps the empty material box onto the top plate of the hopper. Then, a new material box is clamped, and the above steps are repeated to achieve uninterrupted feeding. In this embodiment, through the cooperation of the feeding conveyor 42, the feeding clamping mechanism 45 and the feeding pusher 44, the automated feeding of the products to be welded can be realized. The degree of automation is high, the work efficiency is high, and a lot of human resources can be saved, greatly reducing labor costs and making it highly practical.

[0049] In one embodiment, the feeding and pushing mechanism 44 includes a pushing mounting base 442 mounted on one side of the material box baffle 43, a pushing drive mechanism 443 mounted on the pushing mounting base 442, a first slide rail module 444 mounted on its top along the length direction of the pushing mounting base 442, and a pushing sliding seat 445 slidably arranged on the first slide rail module 444 and connected to the pushing drive mechanism 443; the feeding push rod 441 is mounted on one end of the pushing sliding seat 445; the feeding clamping mechanism 45 includes a clamping Y-axis translation mechanism 451 arranged along the conveying direction of the feeding conveying mechanism 42, and a clamping Y-axis translation mechanism 451. The translation mechanism 451 is connected to a clamping translation frame 452, a clamping Z-axis lifting mechanism 453 installed on one side of the clamping translation frame 452, and a clamping lifting seat 454 slidably arranged on the other side of the clamping translation frame 452 and connected to the clamping Z-axis lifting mechanism 453; a first gripper 455 is installed on one side of the clamping lifting seat 454; a first Z-axis lifting mechanism 456 is also installed on the clamping lifting seat 454, and the first Z-axis lifting mechanism 456 is also driven to connect a first lifting seat 457; a second gripper 458 is also installed on one side of the first lifting seat 457 at a position corresponding to the first gripper 455.

[0050] In this embodiment, the pusher drive mechanism 443 includes a pusher rotary motor mounted on a pusher mounting base 442, a drive wheel connected to the output shaft of the pusher rotary motor, a driven wheel mounted on the pusher mounting base 442, and a synchronous belt wound between the drive wheel and the driven wheel. A pusher connecting block 446 is also mounted on the pusher sliding seat 445, and the pusher connecting block 446 is fixedly connected to one side of the synchronous belt. Driven by the pusher rotary motor, the pusher sliding seat 445 can slide along the first slide rail module 444 via the synchronous belt and the pusher connecting block 446, thereby driving the feeding pusher 441 to move, so that the feeding pusher 441 pushes the product to be welded out of the material box, which is simple and convenient.

[0051] In addition, a pusher limiting seat 447 is also installed on the top of the pusher mounting base 442, and the pusher limiting seat 447 is arranged near one end of the first slide rail module 444; a first buffer spring 448 is also connected between the pusher limiting seat 447 and the pusher sliding seat 445. When the feeding pusher 441 pushes the product and then resets, the force generated during the reset can be buffered by the first buffer spring 448.

[0052] Meanwhile, the clamping Y-axis translation mechanism 451, the clamping Z-axis lifting mechanism 453, and the first Z-axis lifting mechanism 456 can all be directly coupled with a motor lead screw, without any restrictions. Through the clamping Y-axis translation mechanism 451 and the clamping Z-axis lifting mechanism 453, the clamping lifting seat 454 can be driven to perform translation and lifting movements to adjust the positions of the first gripper 455 and the second gripper 458, so as to facilitate the clamping of the material box. At the same time, under the drive of the first Z-axis lifting mechanism 456, the first lifting seat 457 can be driven to move the second gripper 458 closer to or away from the first gripper 455, thereby realizing the clamping and release of the material box.

[0053] In addition, the second gripper 458 includes a gripper fixing block 4581 and a gripper floating block 4582; the gripper fixing block 4581 is fixedly installed on the first lifting seat 457, and a first mounting groove is also provided at one bottom end of the gripper fixing block 4581; a first rotating shaft 4583 is also connected between the inner walls of the two sides of the first mounting groove, and a torsion spring is also installed on the first rotating shaft 4583; the gripper floating block 4582 is arranged below the gripper fixing block 4581, and a first extension block 4584 extends upward from one top end of the gripper floating block 4582; the first extension block 4584 is inserted into the first mounting groove and is movably sleeved on the first rotating shaft 4583 by the torsion spring. In this embodiment, the gripper floating block 4582 of the second gripper 458 is movably sleeved on the first rotating shaft 4583 via a torsion spring. It can rotate relative to the first rotating shaft 4583 and can automatically reset. When gripping the material box, it has a certain buffering effect to avoid damaging the material box. At the same time, the bottom of the gripper floating block 4582 has an arc-shaped outward convex structure. When gripping the material box, the top side of the material box can slide along the surface of the gripper floating block 4582 to one end of the gripper floating block 4582. This ensures that the outward convex part of the gripper floating block 4582 is located inside the material box, thereby generating resistance to the material box and preventing the material box from falling off the two grippers, ensuring the stability of the material box gripping.

[0054] In one embodiment, the feeding and conveying mechanism 42 includes a feeding and conveying motor mounted on the hopper frame 41, and a feeding and conveying belt module connected to the feeding and conveying motor. Driven by the feeding and conveying motor, the feeding and conveying belt module can be driven to operate, thereby realizing the conveying of the material box, which is simple and convenient.

[0055] In one embodiment, the feeding and conveying device 1 includes two conveying track frames 11, a material transfer mechanism 12, and a material pressing mechanism 13. The two conveying track frames 11 are arranged in parallel and spaced apart, and each of the two conveying track frames 11 has a track groove 111 along its length on its opposite side. The material transfer mechanism 12 and the material pressing mechanism 13 are both arranged close to the two conveying track frames 11. The material transfer device can push the product to be welded into the track groove 111, and the material transfer mechanism 12 can push the product to be welded along the track groove 111 to the bottom of the product welding mechanism. Then, the material pressing mechanism 13 presses and fixes the product to be welded so that the product welding mechanism can weld the product. After the product welding is completed, the material pressing mechanism 13 releases the product, and the material transfer mechanism 12 continues to push the product forward to feed it. This method is simple and efficient.

[0056] Furthermore, the material transfer mechanism 12 includes a material transfer translation mechanism 121 arranged near one of the conveyor rail frames 11, a material transfer translation seat 122 connected to the material transfer translation mechanism 121, and a material transfer module installed on the material transfer translation seat 122; the material transfer module includes a material transfer lifting assembly 123, a material transfer connecting rod 124 connected to the material transfer lifting assembly 123, and a material transfer push rod 125 installed on the material transfer connecting rod 124; one end of the material transfer push rod 125 extends to the upper part between the two conveyor rail frames 11, and a material transfer fixing block 126 is also installed at the end of the material transfer push rod 125 extending to the upper part between the two conveyor rail frames 11; a material transfer push block 127 is also installed on the material transfer fixing block 126, and the lower part of the material transfer push block 127 is inserted into the space between the two conveyor rail frames 11.

[0057] In this embodiment, the material transfer lifting assembly 123 of the material transfer module includes a material transfer lifting cylinder. Driven by the material transfer lifting cylinder, the material transfer connecting rod 124 can be driven to move the material transfer push rod 125 up and down. During operation, firstly, the feeding and conveying device pushes the product to be welded between the two conveying rail frames 11, and inserts both ends of the product into a rail groove 111 respectively. Subsequently, the material transfer translation mechanism 121 drives the material transfer translation seat 122 to move the material transfer module, so that the material transfer push block 127 is located at the end of the conveying rail frame 11 used for feeding. Then, under the drive of the material transfer lifting assembly 123, Under the action, the material transfer pusher 127 descends and is inserted between the two conveyor rail frames 11; then, driven by the material transfer mechanism 121, the material transfer pusher 127 pushes the product forward along the rail slide 111. After the product moves to the welding area (i.e., at the pressure mechanism 13 and the product welding mechanism), the pressure mechanism 13 will press and fix the product so that the product welding mechanism can weld the product. After the welding is completed, the material transfer pusher 127 will continue to push the product forward until it moves to the next process. This cycle repeats, which can realize continuous material transfer of the product with fast material transfer speed and high material transfer efficiency.

[0058] In one embodiment, the material transfer mechanism 121 includes a dual-actuator linear motor; two material transfer seats 122 are provided, and the two material transfer seats 122 are respectively connected to one of the actuators of the dual-actuator linear motor; a material transfer module is installed on each material transfer seat 122, and a material transfer fixing plate 128 is also installed on the material transfer push rod 125 of one of the material transfer modules; two material transfer fixing blocks 126 are provided in one of the material transfer modules, and the two material transfer fixing blocks 126 are installed at intervals on the material transfer fixing plate 128. In this embodiment, driven by a dual-actuator linear motor, two material transfer seats 122 can be driven to perform translational movements, thereby pushing the product located between the two conveyor rail frames 11 through the two material transfer modules, which can further improve the product transfer efficiency. At the same time, one of the material transfer modules has two material transfer fixing blocks 126 (the material transfer module is arranged near the unloading end of the conveyor rail frame 11), and one of the material transfer fixing blocks 126 is arranged near the next process (i.e., another feeding device 4). Through the material transfer fixing block 126, the product can be easily pushed from the conveyor rail frame 11 into the empty material box on the other feeding device 4.

[0059] In one embodiment, the pressing mechanism 13 includes a pressing base plate 131 arranged below two conveyor rail frames 11; a pressing frame 132 is installed at each of the top two ends of the pressing base plate 131, and the two conveyor rail frames 11 are located between the two pressing frames 132; a pressing claw 133 is also installed on the pressing frame 132, and one end of the pressing claw 133 extends to the upper part between the two conveyor rail frames 11; a pressing lifting mechanism 134 is also installed on the pressing base plate 131, and the pressing lifting mechanism 134 is also driven to connect a first pressing lifting block 135; the first pressing lifting block 135 is located below the space between the two conveyor rail frames 11. When the product is conveyed between the first pressing lifting block 135 and the pressing jaw 133, the pressing lifting mechanism 134 can drive the first pressing lifting block 135 to rise, thereby lifting the product to the pressing jaw 133. Through the cooperation of the two, the product can be pressed and fixed so that the product welding mechanism can weld the product.

[0060] In one embodiment, the pressing and lifting mechanism 134 includes a rotation drive module 1341, a rotation shaft 1342, a first cam 1343, and a pressing lifting seat 1344; the rotation shaft 1342 is arranged between two pressing frames 132, and the first cam 1343 is mounted on the rotation shaft 1342; a lifting guide rail assembly is installed on each of the opposite sides of the two pressing frames 132 in the vertical direction, and the pressing lifting seat 1344 is arranged above the rotation shaft 1342, with both ends of the pressing lifting seat 1344 slidably connected to the pressing frame 132 via a lifting guide rail assembly; the pressing lifting seat 1344... A first cam follower 1345 is also installed on one side of 344 corresponding to the first cam 1343, and the first cam follower 1345 is in contact with the surface of the first cam 1343; the first pressing lifting block 135 is installed on the top end of the pressing lifting seat 1344; the rotation drive module 1341 is connected to the rotation shaft 1342, and the rotation drive module 1341 is at least used to drive the rotation shaft 1342 to drive the first cam 1343 to rotate; the first cam 1343 is used to drive the pressing lifting seat 1344 to perform lifting and lowering movements via the first cam follower 1345 when rotating.

[0061] In this embodiment, the rotation drive module 1341 includes a rotation drive motor, a first drive wheel connected to the output shaft of the rotation drive motor, a first driven wheel mounted on the rotation shaft 1342, and a first synchronous belt wound between the first drive wheel and the first driven wheel. Driven by the rotation drive motor, the rotation shaft 1342 can be driven via the first drive wheel, the first synchronous belt, and the first driven wheel. When the rotation shaft 1342 rotates, it can drive the first cam 1343 to rotate. Since the first cam 1343 contacts the first cam follower 1345, when the protruding part of the first cam 1343 contacts the first cam follower 1345, it will exert a force on the first cam follower 1345. An upward thrust is generated, and the first cam follower 1345 is installed on the pressure lifting seat 1344. The pressure lifting seat 1344 is slidably connected to the pressure frame 132 via the lifting guide rail assembly. Therefore, it can drive the pressure lifting seat 1344 to rise along the lifting guide rail assembly, and then lift the product to the pressure gripper 133 via the first pressure lifting block 135. When the protruding part of the first cam 1343 gradually stops contacting the first cam follower 1345, the upward force on the first cam follower 1345 will be gradually removed. Then, under the action of gravity, the pressure lifting seat 1344 will drive the first pressure lifting block 135 to slowly descend, thereby realizing the action of driving the pressure lifting seat 1344 to rise and fall.

[0062] Furthermore, in this embodiment, the pressing and lifting mechanism 134 also includes a first tension spring 137; the first tension spring 137 is arranged vertically and is connected between the upper part of one end of the pressing lifting seat 1344 and the top of the pressing base plate 131. When the pressing lifting seat 1344 rises, the first tension spring 137 is in a stretched state. When the pressing lifting seat 1344 needs to descend, the restoring force of the first tension spring 137 drives the pressing lifting seat 1344 to descend and reset quickly and smoothly.

[0063] In one embodiment, a second pressing lifting block 136 is slidably connected to the other end of the top of the pressing lifting seat 1344, and a first connecting rod 1361 is connected to one side of the second pressing lifting block 136; a second connecting rod 1362 is also connected to one side of the first connecting rod 1361 in the vertical direction, and one end of the second connecting rod 1362 extends toward the direction of the rotating shaft 1342; a second cam 1363 is also installed on the rotating shaft 1342, and a second cam follower 1364 is also installed at the end of the second connecting rod 1362 that extends toward the direction of the rotating shaft 1342 and corresponds to the second cam 1363; the second cam follower 1364 contacts the second cam 1363; the second cam 1363 is used to drive the second connecting rod 1362 to drive the first connecting rod 1361 and the second pressing lifting block 136 to perform translational movement when rotating with the rotating shaft 1342 via the second cam follower 1364.

[0064] In this embodiment, one end of the first connecting rod 1361 extends toward one side of the first pressing and lifting block 135, and the second connecting rod 1362 is installed on the end of the first connecting rod 1361 extending toward one side of the first pressing and lifting block 135. One end (lower part) of the second connecting rod 1362 is arranged toward the side of the rotating shaft 1342 away from the second pressing and lifting block 136.

[0065] The protruding portion of the second cam 1363 is misaligned with the protruding portion of the first cam 1343 (in a preferred embodiment, the included angle between them is 90°). When the rotating shaft 1342 rotates, it can drive the second cam 1363 to rotate. Since the second cam 1363 is in contact with the second cam follower 1364, when the protruding portion of the second cam 1363 contacts the second cam follower 1364, it will generate a leftward thrust on the second cam follower 1364. The second cam follower 1364 is mounted on the second connecting rod 1362, which is connected to the second pressing lifting block 136 via the first connecting rod 1361. The second pressing lifting block 136 is slidably arranged on the top of the pressing lifting seat 1344, so it can drive the second pressing lifting block 136 to slide to the left (that is, move closer to the first pressing lifting block 135). The above action is basically consistent with the action of the pressing lifting seat 1344 rising. That is, when the pressing lifting seat 1344 rises, the second pressing lifting block 136 will slowly approach the first pressing lifting block 135. At the same time, the top of the second pressing lifting block 136 is provided with a hook, which will be inserted into the corresponding hole of the product to push the part of the product with the solder pad to the area of ​​the product that needs to be welded, so that the product welding mechanism can weld the product.

[0066] In addition, the pressing and lifting mechanism 134 also includes a second tension spring 138; the second tension spring 138 is arranged horizontally and is connected between one side of one of the pressing frames 132 and one end of the second pressing and lifting block 136. When the second pressing and lifting block 136 moves closer to the first pressing and lifting block 135, it will stretch the second tension spring 138. After the product welding is completed, the second pressing and lifting block 136 can be driven to quickly reset (i.e., move away from the first pressing and lifting block 135) under the restoring force of the second tension spring 138, which is simple and practical.

[0067] In one embodiment, the welding device 2 further includes a welding mounting frame 28, a welding X-axis translation mechanism 281 mounted on the welding mounting frame 28, a welding Y-axis translation mechanism 282 connected to the welding X-axis translation mechanism 281, and a welding translation plate 283 connected to the welding Y-axis translation mechanism 282; the product welding mechanism and the visual positioning mechanism 29 are both mounted on the welding translation plate.

[0068] In this embodiment, the welding X-axis translation mechanism 281 and the welding Y-axis translation mechanism 282 can directly adopt linear motor modules without limitation. With the cooperation of the two, the welding translation plate 283 can be driven to perform translational movement, thereby adjusting the position of the product welding mechanism to weld the product. In addition, a vision positioning mechanism 29 is also included. The vision positioning mechanism 29 is installed on the welding translation plate 283 and arranged close to the product welding device 2. Through the vision positioning mechanism 29, the area of ​​the product that needs to be welded can be positioned so that the product welding mechanism can weld the product, improving work efficiency.

The welding rotating cylinder 22 is mounted within the first mounting cylinder 26 via the first bearing 261, and one end of the welding rotating cylinder 22 extends outward after passing through the first mounting cylinder 26 and the welding mounting plate 21.

[0070] In this embodiment, one end of the welding lifting cylinder 23 passes through the welding rotating cylinder 22 and is connected to the welding lifting mechanism 25. The welding head 27 for welding products can be installed at the other end of the welding lifting cylinder 23. The welding lifting cylinder 23 has a cylindrical structure and is hollow inside, which facilitates wiring. Since the welding lifting cylinder 23 and the welding rotating cylinder 22 are slidably connected, the welding lifting mechanism 25 can drive the welding lifting cylinder 23 to rise and fall relative to the welding rotating cylinder 22, thereby realizing the lifting function of the welding head 27. At the same time, the end of the welding rotating cylinder 22 that protrudes from the welding mounting plate 21 (the welding mounting plate 21 is a flange) is connected to the welding rotating mechanism 24. The welding rotating cylinder 22 is installed in the first mounting cylinder 26 via the first bearing 261. 4. The welding rotating cylinder 22 can be driven to rotate relative to the first mounting cylinder 26 via the first bearing 261. The rotation of the welding rotating cylinder 22 can drive the welding lifting cylinder 23 to rotate, thereby realizing the rotation function of the welding head 27, so that the welding head 27 can weld the product. In this embodiment, the welding device 2 is based on the first mounting cylinder 26, and the welding rotating cylinder 22 and the welding lifting cylinder 23 are coaxially mounted. With this installation method, while realizing the function of the welding head 27 to perform rotation and lifting movements, it can also ensure the compactness of the overall structure of the device, thereby reducing the installation volume and weight of the device. In addition, the welding head 27 is also equipped with a wire supply mechanism that provides welding wire to it. Both the welding head 27 and the wire supply mechanism can directly use existing products, and there are no restrictions on this.

In this embodiment, installing multiple first cross roller guides on the circumferential direction of the outer wall of the welding lifting cylinder 23 can improve the stability of the lifting of the welding lifting cylinder 23. At the same time, the first cross roller guides can maintain the connection between the welding lifting cylinder 23 and the welding rotating cylinder 22, so that when the welding rotating cylinder 22 rotates, it can drive the welding lifting cylinder 23 to rotate synchronously.

[0072] Furthermore, each of the first cross roller guides includes a first fixed guide rail 221 and a first sliding guide rail 222 that are slidably connected to each other; the outer wall of the welding lifting cylinder 23 is also provided with a plurality of first mounting grooves along its axial direction, and the inner wall of the welding rotating cylinder 22 is also provided with a plurality of second mounting grooves corresponding to the plurality of first mounting grooves; the first sliding guide rail 222 of each of the first cross roller guides is installed in a first mounting groove, and the first fixed guide rail 221 of each of the first cross roller guides is installed in a second mounting groove.
