[0022] This invention proposes an alignment assembly device 100.

[0023] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 In one embodiment of the present invention, the alignment assembly equipment 100 includes a base 1, a first loading device 2, a second loading device 3, an identification device (not shown in the figure), and a control module. The first loading device 2 includes a support 21 and a first loading stage 22. The support 21 is disposed on the base 1, and the first loading stage 22 is disposed on the support 21. A first clamping groove 22a is formed on the first loading stage 22, and the bottom wall of the first clamping groove 22a is provided with a docking clearance hole 22b. The second loading device 3 includes a first moving device 31, a second moving device 33, and a second loading stage 32. The base 1, the first loading device 2, the second loading device 3 ... Two moving devices 33, a first moving device 31, and a second platform 32 are connected in sequence. A second clamping groove 32a is formed on the second platform 32. The first moving device 31 is used to drive the second platform 32 so that the part to be welded in the second clamping groove 32a is aligned with the part to be welded in the first clamping groove 22a. The second moving device 33 is used to drive the first moving device 31 to approach the first platform 22. An identification device is provided on the first platform 22 or the second platform 32. The control module is electrically connected to the first moving device 31, the second moving device 33, and the identification device, respectively.

[0024] In this embodiment, the alignment assembly device 100 is used to align the first component to be welded with the second component to be welded in spatial orientation before welding.

[0025] Specifically, the base 1 provides a rigid reference for the entire equipment. The first loading device 2, the second loading device 3, the identification device and the control module are all directly or indirectly attached to the base 1, thereby ensuring the relative position stability between the functional modules and reducing the alignment drift caused by foundation vibration or installation error. The shape of the base 1 can be selected according to the requirements of the installation site, and this application does not limit it.

[0026] The first loading device 2 consists of a support 21 and a first loading platform 22. The support 21 is fixed to the base 1, and the first loading platform 22 is fixed to the support 21 and suspended. Its upper surface is recessed to form a first clamping groove 22a. The outline of the first clamping groove 22a corresponds to the shape of the first component to be welded, and can be rectangular, circular, etc. The side of the first clamping groove 22a can be provided with an elastic pressure plate or other clamping mechanism to realize the planar limitation and fixation of the first component to be welded in the first clamping groove 22a. A docking avoidance hole 22b is opened through the bottom wall of the first clamping groove 22a. The size of the docking avoidance hole 22b is larger than the outer contour size of the docking point of the second component to be welded, so that the second component to be welded can pass through unobstructed and dock with the first component to be welded when it rises later.

[0027] The second carrying device 3 includes a first moving device 31, a second moving device 33, and a second carrying platform 32. The top wall of the base 1 is connected to the fixed end of the second moving device 33. The movable end of the second moving device 33 carries the first moving device 31, and the movable end of the first moving device 31 carries the second carrying platform 32. This decomposes the long-stroke transport action into two stages, shortens the single-stage motion inertia, and improves the start-stop response. Specifically, the second moving device 33 is responsible for driving the first moving device 31 to approach or move away from the first carrying platform 22. When the first moving device 31 approaches the first carrying platform 22, the first moving device 31 drives the second carrying platform 32 to adjust the planar position and angle of the second carrying platform 32 so that the second part to be welded is aligned with the first part to be welded. Then, the second moving device 33 is restarted so that the second carrying platform 32 moves further closer to the first carrying platform 22 so that the second part to be welded is docked with the first part to be welded. The upper surface of the second stage 32 is recessed to form a second clamping groove 32a, which is used to fix the second component to be welded. Laterally, it can be equipped with clamping mechanisms such as spring-loaded clamping blocks to prevent component displacement and rotation. In summary, the second moving device 33 is used to drive the first moving device 31, together with the second stage 32, to move closer to or away from the first stage 22, achieving initial approach between the two components to be welded. The first moving device 31 performs minor two-dimensional fine-tuning alignment after approach, ensuring that the docking portion of the second component to be welded coincides with the docking portion of the first component to be welded in the horizontal plane. Subsequently, the second moving device 33 continues to move to complete the docking.

[0028] The identification device can be directly or indirectly fixed to the base 1 and facing the first clamping groove 22a. It can be a CCD (charge-coupled device) or a laser contour sensor, etc., used to collect the relative edges, marker points or contour features of the first and second parts to be welded in real time, and send the image or point cloud data back to the control module in real time. The control module has built-in image processing algorithms and kinematic models, decomposes the identified position deviation into the compensation motion required by the first moving device 31, and drives the first moving device 31 to translate or rotate in the horizontal plane through closed-loop feedback until the deviation is less than the preset threshold. Then, it controls the second moving device 33 to perform the final lifting to complete the physical docking of the two parts to be welded.

[0029] Through the above structure, the first clamping groove 22a and the second clamping groove 32a, based on their independent positioning, achieve gradual alignment and docking of the two components with the help of the identification device and control module; the two-stage moving device separates coarse handling and fine adjustment, ensuring both efficiency and accuracy. Thus, the equipment can complete high-precision docking of complex structures or micro-sized components without manual intervention, providing a consistent initial gap and mating surface for subsequent laser welding, thermoforming welding, or reflow welding, significantly reducing welding defect rates and improving overall production line efficiency.

[0030] Further, please refer to Figures 2 to 5 In one embodiment of the present invention, the first moving device 31 includes a first sliding mechanism 311, a second sliding mechanism 312, and a rotating mechanism 313 connected in sequence. The first sliding mechanism 311 is connected to the base 1. Of the first sliding mechanism 311 and the second sliding mechanism 312, one is configured to move along a first direction, and the other is configured to move along a second direction. The rotating mechanism 313 is configured to rotate about a third direction. The first direction and the second direction are horizontally orthogonal, and the third direction is vertical. The second platform 32 is disposed on the rotating mechanism 313.

[0031] In this embodiment, the first moving device 31 includes a first sliding mechanism 311, a second sliding mechanism 312, and a rotating mechanism 313, which can be stacked from bottom to top. The fixed end of the first sliding mechanism 311 is fixedly connected to the second moving device 33, and the movable end carries the second sliding mechanism 312. The movable end of the second sliding mechanism 312 then carries the rotating mechanism 313. The rotation center axis of the rotating mechanism 313 is vertically upward, and the output end of the rotating mechanism 313 is fixedly connected to the bottom surface of the second platform 32. The first moving device 31, composed of the first sliding mechanism 311, the second sliding mechanism 312, and the rotating mechanism 313, has two orthogonal linear degrees of freedom and one rotational degree of freedom, so that the first direction, the second direction, and the third direction correspond to the X-axis, Y-axis, and Z-axis of the spatial rectangular coordinate system, respectively, that is, the above three directions are mutually perpendicular.

[0032] The first sliding mechanism 311 and the second sliding mechanism 312 are linear displacement platforms, which can be equipped with cross roller guides and servo motor driven screw and nut pairs, linear motors, etc. One of them is configured to move along the first direction, and the other is configured to move along the second direction. The first direction and the second direction are orthogonal in the horizontal plane, thus forming a planar rectangular coordinate system. The rotation axis of the rotating mechanism 313 extends along the third direction, which is perpendicular to the horizontal plane, so that the second stage 32 can complete the rotation around the third direction in the horizontal plane to achieve fine adjustment of the product to be welded and compensate for the relative rotational misalignment of the two parts to be welded due to the deviation of the material placement angle.

[0033] The rotating mechanism 313 can be an ultra-thin direct-drive rotary motor, servo motor, etc.; the second stage 32 can be locked to the output end of the rotating mechanism 313 by screws or positioning pins, so that the geometric center of the second clamping groove 32a is coaxial with the rotation center of the rotating mechanism 313 or maintains a known offset. The control module can directly call the offset parameter when calculating the rotation compensation amount, reducing additional calibration steps.

[0034] By splitting the first moving device 31 into a combination of two-axis orthogonal sliding and one-axis rotation, the equipment gains three-degree-of-freedom independent adjustment capability in the horizontal plane while maintaining its original vertical feeding capability. When facing rectangular, cross-shaped or angle-sensitive solder pads, the rotating mechanism 313 can be used to rotate and align the marking point or edge of the second part to be welded with the corresponding feature of the first part to be welded. Then, the first sliding mechanism 311 and the second sliding mechanism 312 are used to complete the center translation alignment. Finally, the second moving device 33 performs axial bonding, providing a more consistent bonding posture for subsequent laser welding or thermocompression welding, reducing the risk of solder joint stretching or incomplete welding caused by angular deviation, and further improving the welding yield and production line first pass rate.

[0035] Further, please refer to Figures 2 to 5 In one embodiment of the present invention, the first platform 22 is provided with a plurality of first clamping slots 22a, and the second carrying device 3 includes a plurality of first moving devices 31 and a plurality of second platforms 32, each second platform 32 being correspondingly disposed on a first moving device 31; the second carrying device 3 also includes a first support plate 34, the plurality of first moving devices 31 being spaced apart on the first support plate 34, and the second moving devices 33 being connected to the first support plate 34, the second moving devices 33 being used to drive the first support plate 34 to bring the plurality of first moving devices 31 closer to the first platform 22.

[0036] In this embodiment, multiple first clamping slots 22a or multiple rows of first clamping slots 22a are arranged linearly on the upper surface of the first platform 22. The internal contour, the shape of the docking avoidance hole 22b, and the limiting structure of each first clamping slot 22a are consistent, so that multiple first parts to be welded in the same tray or magazine can be put in at one time and positioned independently. Correspondingly, the second platform 3 is equipped with the same number of first moving devices 31 and second platforms 32 as the first clamping slots 22a. Each second platform 32 is fixed to the movable end of the corresponding first moving device 31. The fixed ends of all first moving devices 31 are locked to the same first bearing plate 34 at intervals. The first bearing plate 34 is then fixed to the movable end of the second moving device 33, thereby realizing many-to-many parallel alignment. The second moving device 33 only needs to drive the first bearing plate 34 to lift as a whole to complete the initial approach of all channels at the same time, reducing the cost and space occupation caused by the repeated arrangement of lifting mechanisms in multiple workstations. The first support plate 34 can be a flat plate made of lightweight aluminum alloy or carbon fiber composite material, with an array of threaded holes or locating pin holes machined on the upper surface for fixing the first moving device 31.

[0037] By arranging multiple first clamping slots 22a on the first loading platform 22 and arranging an equal number of first moving devices 31 and second loading platforms 32 on the side of the second loading device 3, and then using the first bearing plate 34 to achieve overall lifting and sharing, the equipment can significantly improve production efficiency and reduce the cost per unit while maintaining high-precision alignment.

[0038] Further, please refer to Figure 2 and Figure 3 In one embodiment of the present invention, the second moving device 33 includes at least two third sliding mechanisms 331, a second bearing plate 332, and a first lifting mechanism 333; the at least two third sliding mechanisms 331 are spaced apart on the base 1 and are all connected to the second bearing plate 332, and the first lifting mechanism 333 connects the second bearing plate 332 and the first moving device 31; the third sliding mechanism 331 is configured to move along a second direction, which is horizontal, and the first lifting mechanism 333 is configured to move along a third direction, which is vertical.

[0039] In this embodiment, at least two third sliding mechanisms 331 are fixedly mounted on the base 1 at intervals and are both located on the same side of the bracket 21 and are symmetrically connected to the bottom wall of the second bearing plate 332. The lifting mechanism is located on the top wall of the second bearing plate 332 and between the two symmetrically arranged third sliding mechanisms 331. That is, the projections of the two third sliding mechanisms 331 on the horizontal plane are symmetrical about the projection of the lifting mechanism on the horizontal plane. Each third sliding mechanism 331 includes a track and a slider that are slidably connected to each other. The guide rails of both third sliding mechanisms 331 extend horizontally along the second direction. The second bearing plate 332 is simultaneously fixed to the sliders of all third sliding mechanisms 331, thereby distributing the cantilever load originally borne by a single guide rail to multiple guide rails, reducing the tilt of the second platform 32 caused by single-point deformation, and ensuring that the second part to be welded remains parallel to the first part to be welded throughout the lifting process. The fixed end of the first lifting mechanism 333 is connected to the central area of ​​the second bearing plate 332, and the movable end extends upward and connects to the bottom of the first bearing plate 34, allowing the first moving device 31, the second platform 32, and the second part to be welded held by it to obtain a degree of freedom along the third direction. The third sliding mechanism 331 can also be a combination of a heavy-duty ball linear guide rail and a servo motor driven screw and nut pair. The first lifting mechanism 333 can be a servo motor driven ball screw jack, scissor mechanism, etc.

[0040] Further, please refer to Figures 6 to 8In one embodiment of the present invention, the first clamping groove 22a is square in shape; a first protruding rib 221 and a second protruding rib 222 are fixedly provided on the first platform 22, and the first protruding rib 221 and the second protruding rib 222 are perpendicular to each other; a first gripper 223 and a second gripper 224 are movably provided on the first platform 22, the first gripper 223 is arranged opposite to the first protruding rib 221 and is configured to be able to approach or move away from the first protruding rib 221, and the second gripper 224 is arranged opposite to the second protruding rib 222 and is configured to be able to approach or move away from the second protruding rib 222; the first protruding rib 221, the second protruding rib 222, the first gripper 223, the second gripper 224 and the first platform 22 surround to form the first clamping groove 22a.

[0041] In this embodiment, the first clamping groove 22a is designed as a square semi-open space. The first protruding rib 221 and the second protruding rib 222, which are perpendicular to each other, are used as reference angles. With the cooperation of the movable first gripper 223 and the second gripper 224, the clamping and positioning of the first component to be welded is realized.

[0042] Specifically, the first rib 221 and the second rib 222 are integrally machined or screwed onto the upper surface of the first stage 22. The two are at right angles and intersect at one corner of the square first clamping groove 22a, forming an L-shaped rigid reference wall. The first gripper 223 and the second gripper 224 are respectively arranged on opposite sides of the L-shaped rigid reference wall. They can reciprocate along the miniature linear guide rail or slide groove built into the first stage 22. The direction of movement is perpendicular to the corresponding rib, thereby enclosing an adjustable square space with the two ribs. This cavity is the first clamping groove 22a. Its size can be infinitely contracted or expanded in the same plane to adapt to square first welding parts with different side lengths without replacing the entire stage.

[0043] The first gripper 223 and the second gripper 224 can be driven by a miniature cylinder, a voice coil motor, or a semi-automatic scheme using a manually operated gripper head and a compression spring. When the first gripper 223 and the second gripper 224 close synchronously, the adjacent sides of the first component to be welded are respectively pressed against the inner surfaces of the first protruding rib 221 and the second protruding rib 222 to achieve angular positioning. Subsequently, the first gripper 223 and the second gripper 224 maintain a low-pressure clamping state, which both fixes the component and avoids excessive deformation, providing a stable field of view for the identification device.

[0044] Further, please refer to Figures 6 to 8In one embodiment of the present invention, the first stage 22 is further provided with a guide 225, which is arranged along the sliding direction of the first gripper 223. The guide 225 is provided with a fixing member 226, a sliding member 227, and a first elastic member 228. The first gripper 223 is disposed on the sliding member 227. The fixing member 226 is fixedly connected to the guide 225, the sliding member 227 is slidably connected to the guide 225, and the first elastic member 228 connects the sliding member 227 and the fixing member 226. The sliding member 227 is used to push the first gripper 223 closer to the first rib 221; and / or, the first platform 22 is provided with a guide groove 22c, the guide groove 22c is arranged along the sliding direction of the second gripper 224, the second gripper 224 is slidably disposed in the guide groove 22c, and a second elastic member 229 is also provided in the guide groove 22c, the second elastic member 229 connects the second gripper 224 and the inner wall of the guide groove 22c and is used to push the second gripper 224 closer to the second rib 222.

[0045] In this embodiment, the first gripper 223 and the second gripper 224 are respectively equipped with elastic self-resetting structures, so that the clamping action can maintain a constant clamping force without continuous external power, thereby reducing system complexity and energy consumption.

[0046] Specifically, for the first gripper 223, a guide 225 is fixed on the surface of the first stage 22. The guide 225 can be a cylindrical guide rail, a rectangular slide rail, or an integrally machined boss rib. Its length direction is parallel to the sliding direction of the first gripper 223. The guide 225 is provided with a fixing member 226, a sliding member 227, and a first elastic member 228. The fixing member 226 and the guide 225 can be fixed and locked by bolts. The sliding member 227 slides with the guide 225 and can slide along the axial direction. The first gripper 223 is screwed on the top of the sliding member 227. The first elastic member 228 is located between the fixing member 226 and the sliding member 227 and can be a compression spring, a leaf spring, etc. Its pre-compression amount is adjustable by the installation position of the fixing member 226. Thus, without an external air source or motor, an elastic thrust pointing towards the first protruding rib 221 is continuously applied, so that the first gripper 223 automatically retracts and fits against the side of the first part to be welded, realizing flexible clamping.

[0047] For the second gripper 224, a guide groove 22c is directly recessed on the surface of the first stage 22. The cross-section of the guide groove 22c can be rectangular, T-shaped, or dovetail-shaped, and its length direction is parallel to the sliding direction of the second gripper 224. A slider that matches the cross-section of the guide groove 22c is integrally machined or detachably connected to the bottom of the second gripper 224. A micron-level gap is left between the slider and the wall of the guide groove 22c and it is coated with grease to reduce sliding resistance. A second elastic element 229 is also provided in the guide groove 22c. One end of the second elastic element 229 abuts against the end wall of the groove, and the other end abuts against the second gripper 224 or the slider. The second elastic element 229 can be a compression spring, a leaf spring, etc. After installation, it is in a compressed state and continuously pushes the second gripper 224 close to the second protruding rib 222. The operator or robot can push the first gripper 223 and the second gripper 224 to expand the second clamping groove 32a. The two elastic elements store energy synchronously. After the first part to be welded is placed in, the first gripper 223 and the second gripper 224 are released. The first gripper 223 and the second gripper 224 automatically retract, completing the locking of the first part to be welded. No additional sensors or control signals are required, simplifying the operation process.

[0048] Further, please refer to Figure 5 In one embodiment of the present invention, the second clamping groove 32a is square in shape; a third protruding rib 321 and a fourth protruding rib 322 are fixedly provided on the second stage 32, and the third protruding rib 321 and the fourth protruding rib 322 are perpendicular to each other; a third gripper 323 and a fourth gripper 324 are movably provided on the second stage 32, the third gripper 323 is arranged opposite to the third protruding rib 321 and is configured to be close to or away from the third protruding rib 321, and the fourth gripper 324 is arranged opposite to the fourth protruding rib 322 and is configured to be close to or away from the fourth protruding rib 322; the third protruding rib 321, the fourth protruding rib 322, the third gripper 323, the fourth gripper 324 and the second stage 32 surround to form the second clamping groove 32a.

[0049] In this embodiment, the second clamping groove 32a is also designed as a square semi-open space. Specifically, the upper surface of the second stage 32 is integrally machined or detachably fixed with the third rib 321 and the fourth rib 322 by fasteners such as screws. The two ribs intersect perpendicularly to form an L-shaped rigid reference wall. The third gripper 323 and the fourth gripper 324 are respectively arranged on opposite sides of the L-shaped rigid reference wall and can reciprocate along the miniature guide rail or slide groove built into the second stage 32. The direction of movement is perpendicular to the corresponding rib, thereby enclosing an adjustable square space with the two ribs. This space is the second clamping groove 32a.

[0050] The driving method of the third gripper 323 and the fourth gripper 324 can be consistent with that of the first gripper 223 and the second gripper 224, using a miniature cylinder, voice coil motor, etc., or a semi-automatic scheme with manually operated gripper heads and compression springs can be used. When the third gripper 323 and the fourth gripper 324 close, the two adjacent sides of the second part to be welded are respectively pressed against the third protruding rib 321 and the fourth protruding rib 322.

[0051] Further, please refer to Figure 5 In one embodiment of the present invention, a first driving member 325 and a second driving member 326 are provided on the second stage 32; the first driving member 325 has a first fixed part 3251 and a first movable part 3252, and a third gripper 323 is disposed on the first movable part 3252. The first fixed part 3251 and the first movable part 3252 are connected in a transmission manner to drive the third gripper 323 to approach or move away from the third protruding rib 321; the second driving member 326 has a second fixed part 3261 and a second movable part 3262, and a fourth gripper 324 is disposed on the second movable part 3262. The second fixed part 3261 and the second movable part 3262 are connected in a transmission manner to drive the fourth gripper 324 to approach or move away from the fourth protruding rib 322.

[0052] In this embodiment, the third gripper 323 and the fourth gripper 324 are respectively equipped with independently controllable first drive member 325 and second drive member 326, so that the clamping force, speed and stroke can be adjusted in real time according to the material and size of the second part to be welded. The first drive member 325 and the second drive member 326 can adopt various linear actuators, such as miniature cylinders, voice coil motors, servo screw slides, etc. For example, if a miniature cylinder solution is selected, the first drive member 325 and the second drive member 326 are both double-acting cylinders. At this time, the first fixed part 3251 and the second fixed part 3261 correspond to the cylindrical shell of the cylinder. The tail of the shell is provided with a trunnion or flange, which is locked to the surface or side wall of the second stage 32 by screws to achieve radial and axial positioning. The first movable part 3252 and the second movable part 3262 are the piston rods of the cylinder. The front end of the piston rod is connected to the transfer member by bolts. The transfer member is then connected to the third gripper 323 or the fourth gripper 324, thereby transmitting the linear thrust of the piston rod to the gripper. For example, if a servo screw slide solution is selected, the first drive unit 325 and the second drive unit 326 are both slide modules that integrate servo motors and micro ball screws. In this case, the first fixed part 3251 and the second fixed part 3261 correspond to the aluminum alloy base of the slide. The base has countersunk holes at both ends and is fixed to the surface of the second stage 32 by screws. The first movable part 3252 and the second movable part 3262 are the sliders on the screw nut. The sliders are connected to the third jaw 323 or the fourth jaw 324 by bolts or slots to achieve quick assembly and disassembly.

[0053] Further, please refer to Figure 1 and Figure 6In one embodiment of the present invention, the alignment assembly equipment 100 further includes a pressing device 4, which includes a second lifting mechanism 41, a pressing plate 42, a pressure gauge (not shown in the figure), and a contoured protective cover 43. The second lifting mechanism 41 is disposed on the base 1 or the bracket 21, the pressing plate 42 is connected to the second lifting mechanism 41, the pressing plate 42 is provided with a mounting hole 42a, the contoured protective cover 43 is disposed in the mounting hole 42a and connected to the pressure gauge, the pressure gauge is electrically connected to the control module, and the contoured protective cover 43 is provided with a welding avoidance hole. The second lifting mechanism 41 is used to drive the pressing plate 42 to bring the contoured protective cover 43 close to the first clamping groove 22a, and the contoured protective cover 43 is used to abut against and cover the product to be welded in the first clamping groove 22a.

[0054] In this embodiment, the pressing device 4 is used to apply a controllable downward pressing force to the first component to be welded after alignment, while shielding the non-welding area to reduce damage to sensitive parts from welding spatter or heat radiation. The pressing plate 42, pressure gauge, and contoured protective cover 43 of the pressing device 4 are all arranged above the second carrier device, providing a downward pressure opposite to the lifting of the second moving device 33, so that the two components to be welded maintain a constant contact pressure during welding.

[0055] Specifically, the second lifting mechanism 41 can be set with reference to the first lifting mechanism 333. Its fixed end is fixedly connected to the bracket 21 or the base 1, and its movable end can be screwed to the lower pressure plate 42 to ensure that the lifting trajectory is coaxial with the center of the first clamping groove 22a. The lower pressure plate 42 is a lightweight high-rigidity aluminum plate or carbon fiber plate. The plate surface is provided with array mounting holes 42a for mounting the contour protective cover 43. For example, when the contour protective cover 43 is used to cover the lens, it will have a raised part. The raised part can extend into the mounting hole 42a, and another part extends to the bottom wall of the lower pressure plate 42 and is connected to the lower pressure plate 42 by bolts or buckles. The pressure gauge can be a piezoresistive or piezoelectric pressure sensor, etc., and is located on the side of the contoured protective cover 43 facing the first stage 22 or between the contoured protective cover 43 and the lower pressure plate 42. It detects the force exerted by the contoured protective cover 43 on the first part to be welded during the pressing process in real time. The detection signal is connected to the control module via a shielded cable. The control module adjusts the drive current of the second lifting mechanism 41 according to the preset pressure threshold to achieve precise pressure control and avoid damage to the part to be welded or excessive compression due to overpressure. The contoured protective cover 43 can be a thin-walled shell made of high-temperature resistant polyether ether ketone (PEEK), polyimide (PI), or anodized aluminum, etc. Its lower surface contour conforms to the non-welding area of ​​the upper surface of the first part to be welded. Welding avoidance holes are opened on the contoured protective cover 43, and the hole diameter is slightly larger than the outer diameter of the laser spot or the hot press welding head, so that the welding area of ​​the first part to be welded is exposed. For example, the bottom of the lower pressure cover is provided with multiple sliding rods, and the contoured protective cover 43 is slidably connected to the sliding rods. When not pressed down, the contoured protective cover 43 is away from the lower pressure plate 42, and the pressure gauge is located on the side of the contoured protective cover 43 facing the lower pressure plate 42. After pressing down, the contoured protective cover 43, the pressure gauge and the lower pressure plate 42 abut against each other in sequence, and the pressure value obtained by the pressure gauge can reflect the pressure between the two parts to be welded.
