Description

Technical Field

[0001] This application relates to the field of welding technology, specifically to a flexible clamping device and welding equipment. Background Technology

[0002] In actual production operations, due to limitations such as product structure, different material requirements, and processing procedures, components need to be broken down into multiple workpieces for separate processing. During assembly, these workpieces need to be welded together to form a complete assembly. Because workpiece processing has upper and lower tolerance limits, workpieces, such as spring clips and bottom covers, cannot be directly pressed together during welding. Laser welding, however, requires the workpieces to be pressed firmly together; gaps between workpieces will prevent a secure weld. Currently, spring clips are typically mounted on a fixture, which is used to fix the spring clips to the bottom cover according to dimensional requirements. Screws are then used to tighten the spring clips before welding. After welding, the screws are loosened and the fixture is removed, thus completing the welding process. However, the current method of clamping workpieces is cumbersome, inconvenient to operate, and prone to mis-clamping, resulting in low welding yield. Summary of the Invention

[0003] In view of the above, it is necessary to propose a flexible clamping device and welding equipment to achieve the effect of flexibly clamping the second workpiece to the first workpiece, thereby reducing the probability of clamping failure and improving the welding yield.

[0004] This application provides a flexible clamping device, including:

[0005] The support mechanism includes a support position for supporting the first workpiece;

[0006] A flexible clamping mechanism is disposed on the bearing mechanism and adjacent to the bearing position, for flexibly clamping a second workpiece to the inner side of the first workpiece. The flexible clamping mechanism includes a base, a mounting seat, a sliding member, an elastic member, and an eccentric member. The base is disposed on the bearing mechanism and adjacent to the bearing position. The mounting seat is rotatably disposed on the base. The sliding member is slidably disposed on the mounting seat and includes an assembly portion located outside the mounting seat. The assembly portion is used to adapt to and receive the second workpiece, and the side of the assembly portion receiving the second workpiece faces the mounting seat. The elastic member is disposed inside the mounting seat and abuts against the mounting seat and the sliding member. The eccentric member is rotatably disposed on the mounting seat. The eccentric member is located between the assembly portion and the elastic member or on the side of the elastic member away from the assembly portion. The eccentric member is used to eccentrically abut against the sliding member.

[0007] In some embodiments, the sliding member further includes a sliding portion connected to the assembly portion, the sliding portion having a through hole extending along the sliding direction of the sliding member; the mounting base includes a lower cover, an upper cover, and a stop member, the lower cover being rotatably disposed on the base, the upper cover being connected to the lower cover, the sliding portion being slidably disposed between the upper cover and the lower cover, the stop member being connected between the upper cover and the lower cover and located within the through hole, the elastic member being located within the through hole and abutting against the stop member and the sliding portion, the eccentric member being rotatably disposed between the upper cover and the lower cover and located within the through hole and located on the side of the stop member away from the elastic member, or the eccentric member being located outside the through hole and located on the side of the sliding portion away from the assembly portion.

[0008] In some embodiments, the flexible clamping mechanism further includes a first magnet disposed on the base, the first magnet being used to magnetically attract the mounting base.

[0009] In some embodiments, the flexible clamping mechanism further includes a second magnet disposed in the assembly portion, the second magnet being used to magnetically attract the second workpiece.

[0010] In some embodiments, the flexible clamping mechanism further includes a limiting member disposed on the assembly portion. The limiting member is used to abut against the upper side of the first workpiece when the assembly portion, carrying the second workpiece, approaches the first workpiece, thereby limiting the assembly portion.

[0011] In some embodiments, the flexible clamping mechanism further includes an eccentric handle connected to the eccentric member and located outside the mounting base, the eccentric handle being used to receive external forces to cause the eccentric member to rotate eccentrically.

[0012] In some embodiments, the bearing mechanism includes a bearing seat, a fixed block, a movable block, and a plurality of positioning posts. The bearing position is disposed on the bearing seat, the fixed block is disposed on the bearing seat and located between the bearing position and the base, the movable block is slidably and elastically disposed on the bearing seat and is located on opposite sides of the bearing position, respectively, and the plurality of positioning posts are disposed on the bearing seat and distributed on the other opposite sides of the bearing position. The fixed block, the movable block, and the plurality of positioning posts are used to position the first workpiece at the bearing position.

[0013] In some embodiments, the bearing mechanism further includes a clamping component disposed on the bearing seat and adjacent to the bearing position, the clamping component being used to clamp the first workpiece onto the bearing position.

[0014] This application also provides a welding device, including:

[0015] The aforementioned flexible clamping device;

[0016] A welding platform includes a base plate, a receiving plate, and a rotary lifting clamping assembly. The receiving plate is inclinedly connected to the base plate. The receiving plate includes a receiving position for receiving the bearing mechanism of the flexible clamping device. The rotary lifting clamping assembly is disposed on the receiving plate and adjacent to the receiving position. The rotary lifting clamping assembly is used to press the bearing mechanism against the receiving position.

[0017] A laser emitting device is disposed adjacent to the welding platform for emitting lasers toward the first workpiece and the second workpiece to weld the first workpiece and the second workpiece.

[0018] In some embodiments, the welding platform further includes a plurality of support members, all of which are disposed on the receiving plate and arranged along the outline of the bearing mechanism, and the plurality of support members are used to support the bearing mechanism.

[0019] The flexible clamping device and welding equipment of this application embodiment support a first workpiece through the bearing position of the bearing mechanism, and a second workpiece is received by the assembly part of the flexible clamping mechanism. After the assembly part receives the second workpiece, the mounting base, sliding member, elastic member and eccentric member are flipped so that the assembly part of the sliding member brings the second workpiece closer to the first workpiece and the second workpiece is positioned opposite to the inner surface of the first workpiece. The eccentric member is rotated so that the eccentric member abuts against the sliding member eccentrically. Under the elastic force of the elastic member, the sliding member moves the second workpiece closer to the inner surface of the first workpiece so that the second workpiece is clamped to the inner surface of the first workpiece. Because the sliding member is subjected to the elastic force of the elastic member, the effect of flexibly clamping the second workpiece to the inner surface of the first workpiece is achieved. The second workpiece and the first workpiece are flexibly abutted without gap, so as to facilitate welding of the first workpiece and the second workpiece.

[0020] The flexible clamping device and welding equipment of this application embodiment can achieve the effect of flexibly clamping the second workpiece to the first workpiece by rotating the eccentric part and flipping the mounting base. The workpiece clamping operation is simple and easy to operate. Furthermore, the second workpiece is flexibly clamped to the first workpiece under the elastic force of the elastic part, which reduces the probability of poor clamping between the first and second workpieces and helps to improve the welding yield.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0086] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0087] Please see Figure 1 This application provides a flexible clamping device 100, which is used to flexibly clamp a second workpiece 3 to a first workpiece 2, so as to facilitate laser welding of the first workpiece 2 and the second workpiece 3. The first workpiece 2 can be a bottom cover, and the second workpiece 3 can be a strip-shaped spring. Specifically, the flexible clamping device 100 is used to flexibly clamp the second workpiece 3 to the inner side 2a of the first workpiece 2.

[0088] Please see Figures 2 to 4 The flexible clamping device 100 includes a supporting mechanism 10 and a flexible clamping mechanism 20. The supporting mechanism 10 includes a supporting position 11 for supporting a first workpiece 2. The flexible clamping mechanism 20 is disposed on the supporting mechanism 10 and adjacent to the supporting position 11, and is used to flexibly clamp a second workpiece 3 to the inner surface 2a of the first workpiece 2. Thus, in actual use, the supporting mechanism 10 supports and fixes the first workpiece 2, while the flexible clamping mechanism 20 flexibly clamps the second workpiece 3 to the inner surface 2a of the first workpiece 2.

[0089] Specifically, the flexible clamping mechanism 20 includes a base 21, a mounting base 22, a sliding member 23, an elastic member 24, and an eccentric member 25. A base 21 is disposed on the support mechanism 10 and adjacent to the support position 11. A mounting seat 22 is rotatably disposed on the base 21 and can be opened and closed relative to the base 21. A sliding member 23 is slidably disposed on the mounting seat 22 and includes an assembly portion 231 located outside the mounting seat 22. The assembly portion 231 is used to adapt to receive a second workpiece 3, and the side of the assembly portion 231 receiving the second workpiece 3 faces the mounting seat 22. An elastic member 24 can be a spring, which is disposed inside the mounting seat 22 and abuts against the mounting seat 22 and the sliding member 23. An eccentric member 25 is rotatably disposed on the mounting seat 22. The eccentric member 25 is located between the assembly portion 231 and the elastic member 24, or the eccentric member 25 is located on the side of the elastic member 24 away from the assembly portion 231. The eccentric member 25 is used to eccentrically abut against the sliding member 23 to move the sliding member 23 or to move the sliding member 23 in the opposite direction under the elastic force of the elastic member 24. The eccentric member 25 is approximately a quarter-eccentric wheel. The assembly part 231 is adapted to the shape of the second workpiece 3, which will not be described in detail here in the embodiments of this application. For further details, please refer to... Figure 4 For ease of understanding and explanation, in this application embodiment, "rotating eccentric member 25" means rotating eccentric member 25 90° in a clockwise direction, and "reverse rotation of eccentric member 25" means rotating eccentric member 25 90° in a counterclockwise direction.

[0090] In this embodiment, the number of flexible clamping mechanisms 20 is two. In actual use, the flexible clamping device 100 can flexibly clamp two second workpieces 3 to the inner surface 2a of the first workpiece 2 at one time, thereby improving the assembly efficiency of the first workpiece 2 and the second workpiece 3. It can be understood that the number of flexible clamping mechanisms 20 can also be more or less, which can be set according to the actual production situation.

[0091] In actual use, the aforementioned flexible clamping device 100 flips the mounting base 22 to open it relative to the base 21. Specifically, the angle at which the mounting base 22 opens relative to the base 21 can be an obtuse angle, for example, 150° to 180°, such as 165°. After opening the mounting base 22, the eccentric member 25 is rotated, causing the eccentric member 25 to eccentrically abut against the sliding member 23, causing the sliding member 23 to move and the assembly part 231 to move away from the mounting base 22, so that a gap is reserved between the second workpiece 3 and the first workpiece 2 when assembling the second workpiece 3 and the first workpiece 2. The gap is filled, and the sliding member 23 compresses the elastic member 24, and the second workpiece 3 is placed on the assembly part 231. After the second workpiece 3 is placed, the mounting base 22 is flipped in the opposite direction so that the mounting base 22 closes relative to the base 21, so that the assembly part 231 brings the second workpiece 3 close to the first workpiece 2. Since the side of the assembly part 231 that receives the second workpiece 3 faces the mounting base 22, the second workpiece 3 and the inner side surface 2a of the first workpiece 2 can face each other. At this time, there is a gap between the inner side surface 2a of the first workpiece 2 and the second workpiece 3, for example, a gap of 1.5mm. The eccentric member 25 is rotated in the opposite direction, causing it to eccentrically abut against the sliding member 23. Under the elastic force of the elastic member 24, the sliding member 23 moves in the opposite direction, causing the assembly part 231 to move closer to the mounting base 22. This clamps the second workpiece 3 onto the inner side surface 2a of the first workpiece 2. At this time, the gap between the inner side surface 2a of the first workpiece 2 and the second workpiece 3 is 0. Because the sliding member 23 is subjected to the elastic force of the elastic member 24, the second workpiece 3 is flexibly clamped onto the inner side surface 2a of the first workpiece 2, effectively reducing the gap between the first workpiece 2 and the second workpiece 3. This is beneficial for welding the first workpiece 2 and the second workpiece 3 and improves the welding yield.

[0092] In this embodiment, the sliding member 23 further includes a sliding part 232 connected to the assembly part 231. The sliding part 232 is generally a rectangular block, and the assembly part 231 is connected to the sliding part 232 so that the sliding member 23 is generally T-shaped. The sliding part 232 has a through hole 233 extending along the sliding direction of the sliding member 23. The mounting base 22 includes a lower cover 221, an upper cover 222, and a stop 223. The lower cover 221 is generally U-shaped and is rotatably mounted on the base 21 via a pivot 224. The upper cover 222 is generally L-shaped and is connected to the lower cover 221 so that the mounting base 22 forms a hollow structure. The sliding part 232 is slidably disposed between the upper cover 222 and the lower cover 221 and stops against the upper cover 222. The stop 223 is connected between the upper cover 222 and the lower cover 221 and stops against the upper cover 222. Located within the through hole 233, the elastic member 24 is located within the through hole 233 and abuts against the stop member 223 and the sliding part 232. Specifically, the elastic member 24 abuts against the first inner sidewall 234 of the stop member 223 and the sliding part 232. The eccentric member 25 is rotatably disposed between the upper cover 222 and the lower cover 221 and is located within the through hole 233 and on the side of the stop member 223 away from the elastic member 24. The eccentric member 25 abuts against the second inner sidewall 235 of the sliding part 232. Thus, by disassembling the mounting base 22 into a lower cover 221, an upper cover 222, and a stopper 223, the sliding member 23, the eccentric member 25, and the elastic member 24 can be assembled into the mounting base 22, simplifying the assembly process of the flexible clamping mechanism 20. By having the eccentric member 25 eccentrically abut against the second inner wall 235 of the sliding part 232, and the elastic member 24 abut against the stopper 223 and the first inner wall 234 of the sliding part 232, the effect of rotating and reversing the eccentric member 25 to move and reverse the sliding member 23 can be achieved, so that the assembly part 231 can move away from and closer to the inner side surface 2a of the first workpiece 2.

[0093] Understandably, in other embodiments, the eccentric member 25 may also be located outside the through hole 233 and on the side of the sliding portion 232 opposite to the mounting portion 231, while the elastic member 24 abuts against the stop member 223 and the second inner sidewall 235 of the sliding portion 232. In this way, the effect of rotating the eccentric member 25 in both directions to move the sliding member 23 in both directions can still be achieved.

[0094] In this embodiment, the base 21 has two protrusions 211 located on both sides of the base 21, and the distance between the two protrusions 211 is adapted to the width of the lower cover 221. Thus, by providing two protrusions 211 on the base 21, when the mounting seat 22 is closed relative to the base 21, the two protrusions 211 limit the mounting seat 22, preventing displacement and ensuring stable operation of the flexible clamping mechanism 20.

[0095] To ensure the mounting base 22 remains stable and does not shift when closed relative to the base 21, in this embodiment, the flexible clamping mechanism 20 further includes a first magnet 26. The first magnet 26 is embedded in the base 21 and magnetically attracts the mounting base 22. Thus, by providing the first magnet 26, when the mounting base 22 is closed relative to the base 21, the first magnet 26 magnetically attracts the mounting base 22, ensuring it is securely fixed to the base 21 and preventing displacement that could affect the fit accuracy between the second workpiece 3 and the first workpiece 2. The mounting base 22 can be made of stainless steel or other materials that can be magnetically attracted by the first magnet 26.

[0096] To ensure the second workpiece 3 is securely placed on the assembly part 231, in this embodiment, the flexible clamping mechanism 20 further includes two second magnets 27, spaced apart on the assembly part 231. Both second magnets 27 are used to magnetically attract the second workpiece 3. Thus, when the second workpiece 3 is placed on the assembly part 231, the second magnets 27 magnetically attract it, ensuring the second workpiece 3 is securely placed on the assembly part 231 and preventing displacement of the second workpiece 3 from affecting the fitting accuracy between the second workpiece 3 and the first workpiece 2. The second workpiece 3 can be made of stainless steel or other materials that can be magnetically attracted by the second magnets 27.

[0097] Understandably, after the first workpiece 2 and the second workpiece 3 are welded together, since the force between the first workpiece 2 and the second workpiece 3 is much greater than the magnetic attraction between the second magnet 27 and the second workpiece 3, the assembly part 231 can be separated from the second workpiece 3 when the eccentric part 25 is rotated.

[0098] To limit the assembly part 231 and ensure the fitting accuracy between the second workpiece 3 and the first workpiece 2, in this embodiment, the flexible clamping mechanism 20 further includes two limiting members 28. The two limiting members 28 are spaced apart at both ends of the assembly part 231. When the assembly part 231, carrying the second workpiece 3, approaches the first workpiece 2, the two limiting members 28 abut against the upper side 2b of the first workpiece 2, thereby limiting the assembly part 231. Thus, by providing the aforementioned limiting members 28, the assembly part 231 abuts against the upper side 2b of the first workpiece 2 when carrying the second workpiece 3, thereby limiting the assembly part 231, ensuring the relative positional accuracy between the second workpiece 3 and the first workpiece 2, and thus ensuring the fitting accuracy between the second workpiece 3 and the first workpiece 2.

[0099] To facilitate the rotation of the eccentric component 25, in this embodiment, the flexible clamping mechanism 20 further includes an eccentric handle 291. The eccentric handle 291 is generally rectangular in shape and is connected to the eccentric component 25 via a connecting rod 292 located on the outside of the mounting base 22. The connecting rod 292 is also generally rectangular. Specifically, the eccentric handle 291 is located on the side of the mounting base 22 opposite to the base 21. The eccentric handle 291 is used to receive external force to rotate the eccentric component 25 eccentrically. Thus, by providing the aforementioned eccentric handle 291, the eccentric component 25 can be rotated by receiving external force through the eccentric handle 291, simplifying operation and saving effort. The external force can be human force or mechanical force.

[0100] In this embodiment, the bearing mechanism 10 includes a bearing seat 12, a fixed block 13, a movable block 14, and a plurality of positioning posts 15. The bearing position 11 is disposed on the bearing seat 12. The shape of the bearing seat 12 can be set according to actual production needs. The number of fixed blocks 13 is equal to the number of flexible clamping mechanisms 20. The fixed blocks 13 are disposed on the bearing seat 12 and located between the bearing position 11 and the base 21 of the corresponding flexible clamping mechanism 20. The movable block 14 is slidably and elastically disposed on the bearing seat 12 and is located on opposite sides of the bearing position 11, respectively, along with the fixed blocks 13. The plurality of positioning posts 15 are disposed on the bearing seat 12 and distributed on the other opposite sides of the bearing position 11. The ends of the positioning posts 15 are approximately conical. The fixed block 13, the movable block 14, and the plurality of positioning posts 15 are used to position the first workpiece 2 of the bearing position 11. Thus, the fixed block 13, the movable block 14 and the multiple positioning posts 15 roughly form the outline of the first workpiece 2. When the first workpiece 2 is placed, the first workpiece 2 is placed on the bearing position 11 and between the fixed block 13, the movable block 14 and the multiple positioning posts 15. The movable block 14 presses the first workpiece 2 against the fixed block 13 under the action of elasticity, thereby realizing the positioning of the first workpiece 2.

[0101] Specifically, the bearing mechanism 10 also includes a pressure block 16 and an elastic member 17. The pressure block 16 is fixedly mounted on the bearing seat 12, and the movable block 14 is slidably disposed within the pressure block 16 and stops within the pressure block 16. The elastic member 17 is disposed within the pressure block 16 and abuts against the movable block 14 and the pressure block 16. The elastic member 17 can be a spring. Thus, by setting the pressure block 16 and the elastic member 17, the function of the movable block 14 sliding and elastically disposed on the bearing seat 12 is realized. The movable block 14 is approximately U-shaped, and the side of the pressure block 16 facing the bearing seat 12 has a groove structure adapted to the movable block 14. This embodiment will not be described in detail here.

[0102] To ensure that the first workpiece 2 can be stably placed on the bearing position 11 of the bearing seat 12, in this embodiment, the bearing mechanism 10 further includes a clamping component 18. The clamping component 18 is disposed on the bearing seat 12 and adjacent to the bearing position 11. The clamping component 18 is used to clamp the first workpiece 2 onto the bearing position 11. There are two clamping components 18, respectively disposed on opposite sides of the bearing position 11. The clamping component 18 can be a clamp or other functional component. Thus, by setting the clamping component 18, the effect of clamping the first workpiece 2 onto the bearing position 11 is achieved, ensuring that the first workpiece 2 can be stably placed on the bearing position 11.

[0103] To facilitate the handling and transportation of the bearing mechanism 10, in this embodiment, the bearing mechanism 10 further includes two bearing handles 19. Each bearing handle 19 is approximately U-shaped and is located on opposite sides of the bearing seat 12. Thus, by providing the aforementioned bearing handles 19, the handling and transportation of the bearing mechanism 10 are facilitated, improving the ease of use of the flexible clamping device 100.

[0104] The flexible clamping device 100 provided in this application embodiment can flexibly clamp the second workpiece 3 to the first workpiece 2 by rotating the eccentric member 25 and flipping the mounting base 22. The workpiece clamping operation is simple and easy to operate. Furthermore, the second workpiece 3 is flexibly clamped to the first workpiece 2 under the elastic force of the elastic member 24, avoiding gaps between the first workpiece 2 and the second workpiece 3, reducing the probability of poor clamping between the first workpiece 2 and the second workpiece 3, and helping to improve the welding yield.

[0105] Please see Figure 5 This application also provides a welding device 1, which is used to flexibly clamp a second workpiece 3 to a first workpiece 2, and to weld the first workpiece 2 and the second workpiece 3. The welding device 1 includes the aforementioned flexible clamping device 100, welding platform 200, and laser emitting device 300.

[0106] Please refer to the above. Figure 6The welding platform 200 includes a base plate 201, a receiving plate 202, and a rotary lifting clamping assembly 203. The receiving plate 202 is inclined relative to the base plate 201, for example, 91°-100°, such as 95°. The receiving plate 202 includes a receiving position 2021 for receiving the bearing mechanism 10 of the flexible clamping device 100. The rotary lifting clamping assembly 203 is disposed on the receiving plate 202 and adjacent to the receiving position 2021, and is used to press the bearing mechanism 10 against the receiving position 2021. A laser emitting device 300 is disposed adjacent to the welding platform 200, and is used to emit laser light toward the first workpiece 2 and the second workpiece 3 to perform laser welding on the first workpiece 2 and the second workpiece 3. In this process, by setting the receiving plate 202 to be inclined relative to the base plate 201, the first workpiece 2 and the second workpiece 3 are also inclined relative to the base plate 201, so as to reserve a light source space for the laser emitting device 300 to emit laser, so that the laser emitted by the laser emitting device 300 can irradiate the first workpiece 2 and the second workpiece 3, thereby performing laser welding on the first workpiece 2 and the second workpiece 3.

[0107] In this embodiment, four rotary lifting clamping assemblies 203 are provided, each located at one of the four corners of the receiving plate 202. Each rotary lifting clamping assembly 203 includes a rotary lifting cylinder 2031 and a clamping member 2032. The rotary lifting cylinder 2031 is located on the receiving plate 202 and connected to the clamping member 2032. The rotary lifting clamping assembly 203 is used to move the clamping member 2032 closer to or further away from the receiving plate 202 and rotate it. Thus, by setting the specific structure of the rotary lifting clamping assembly 203, the effects of avoiding obstruction of the bearing mechanism 10 and pressing the bearing mechanism 10 against the receiving position 2021 are achieved.

[0108] In this embodiment, the clamping member 2032 has a limiting groove 2033, and the welding platform 200 also includes a number of limiting rods 204 equal to the number of the rotary lifting clamping assembly 203. The limiting rods 204 are disposed on the receiving plate 202 and are correspondingly disposed to the clamping member 2032. The cross-sectional area of ​​the end of the limiting rod 204 away from the receiving plate 202 gradually decreases. Thus, when the rotary lifting cylinder 2031 drives the clamping member 2032 to approach the receiving plate 202 and rotates, the limiting groove 2033 of the clamping member 2032 is adapted to be inserted into the limiting rod 204. The cooperation between the limiting rod 204 and the limiting groove 2033 prevents the clamping member 2032 from shifting and releasing the bearing mechanism 10, ensuring that the bearing mechanism 10 can be stably placed on the receiving plate 202.

[0109] In this embodiment, the welding platform 200 further includes multiple support members 205. These support members 205 are all disposed on the receiving plate 202 and arranged along the contour of the bearing mechanism 10. The multiple support members 205 are used to support the bearing mechanism 10. Thus, by providing multiple support members 205, when the bearing mechanism 10 is initially placed on the receiving plate 202, the multiple support members 205 support the bearing mechanism 10, preventing it from falling off the receiving plate 202 and achieving positioning of the bearing mechanism 10. Then, the rotating lifting clamping assembly 203 presses the bearing mechanism 10 firmly onto the receiving plate 202.

[0110] In this embodiment, the welding platform 200 further includes multiple positioning elements 206. These positioning elements 206 are disposed on the receiving plate 202 and located at the receiving position 2021. The multiple positioning elements 206 are adapted to be inserted into the bearing seat 12 of the bearing mechanism 10 to achieve positioning of the bearing mechanism 10. Thus, by setting the aforementioned multiple positioning elements 206, the positioning of the bearing mechanism 10 is achieved, ensuring the welding accuracy and yield of the first workpiece 2 and the second workpiece 3.

[0111] Please see Figure 7 This application embodiment also provides another welding device 4. The welding device 4 of this application embodiment is generally similar in structure to the welding device 1 described above. The difference is that the welding device 4 of this application embodiment also includes a base 400 and a protective cover 500.

[0112] Specifically, the base plate 201 of the welding platform 200 is mounted on the base platform 400, the laser emitting device 300 is mounted on the base platform 400, and wiring or other objects can be installed inside the base platform 400. A protective cover 500 is mounted on the base platform 400 and covers the welding platform 200 and the laser emitting device 300. One side of the protective cover 500 has a transparent observation window 501, through which the welding process inside the welding equipment 1 can be observed. The other side of the protective cover 500 has an entrance / exit 502, through which the carrying mechanism 10 can be easily placed and removed. A sliding window 503 that can move up and down is provided at the entrance / exit 502; the sliding window 503 can also be transparent. In actual use, when it is necessary to take or put away the bearing mechanism 10, the sliding window 503 is pushed upward to facilitate taking or putting away the bearing mechanism 10 from inside the protective cover 500; when it is necessary to weld the first workpiece 2 and the second workpiece 3, the sliding window 503 is pushed downward to close the entrance 502 to prevent welding slag from splashing out and causing injury during welding.
