Description

Technical Field

[0001] This invention relates to the field of connector manufacturing technology, and in particular to a mobile phone connector assembly and welding equipment. Background Technology

[0002] In the consumer electronics sector, mobile phones are core terminal products, and mobile phone connectors are key components ensuring circuit signal transmission and power supply. The quality and efficiency of their manufacturing play a decisive role in improving the overall production capacity of mobile phones. With the continuous upgrading of functions such as 5G communication and fast charging technology, the structural complexity of mobile phone connectors continues to increase, placing more stringent requirements on assembly precision and welding consistency. This has made the connector assembly process a core bottleneck restricting the efficiency improvement of mobile phone production lines.

[0003] Currently, the assembly and soldering of mobile phone connectors is not yet fully automated; it primarily employs a hybrid approach of semi-automated equipment and manual assistance. This approach presents several challenges in practical applications.

[0004] Firstly, the production process is fragmented and involves frequent manual intervention. In the existing process system, the cutting of the top cover material strip, the transfer of individual top covers after cutting, the preliminary assembly of the connector body and the top cover, and the welding of the assembled parts are all carried out independently. This not only significantly extends the welding cycle of a single connector, which is far from meeting the high-efficiency production cycle requirements of mobile phone mass production lines, but also keeps the alignment yield of the top cover and the body at a consistently low level. After welding, problems such as incomplete soldering and misaligned soldering frequently occur, greatly increasing the subsequent rework costs.

[0005] Secondly, the equipment lacks coordination and cooperation capabilities, making it difficult to build a continuous production process. The cutting, welding, and pressurizing equipment used in the existing production process are mostly independently purchased standardized single-machine units. There is a lack of unified control signal interaction mechanisms and efficient material transfer channels between these devices. For example, after the top cover is cut, it needs to be temporarily stored in a tray until a certain quantity is accumulated before being transferred to the assembly station. This results in a long material waiting time between the top cover cutting and assembly processes. Connector bodies, on the other hand, need to be placed one by one onto a transport fixture before being pushed to the welding station. The supply rhythm of these connectors is difficult to match with the processing rhythm of the top cover, frequently resulting in interruptions in production such as "cutting equipment idle waiting for body supply" or "welding equipment running idle waiting for assembly parts to be transported." The overall equipment utilization rate is low, further restricting the improvement of overall production efficiency.

[0006] In summary, technical personnel are urgently needed to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a mobile phone connector assembly and welding equipment, which aims to solve the problems of dispersed production processes, long assembly and welding cycles, and high assembly and welding defect rates in existing designs, while also addressing issues such as weak equipment coordination, easy power outages, and low utilization rates.

[0008] This invention relates to a mobile phone connector assembly and welding equipment, including a machine base, an upper cover material strip unwinding machine, an upper cover material strip conveying machine, an upper cover cutting machine, an upper cover transfer machine, a connector body transport machine, a laser welding machine, and a pressure locking machine;

[0009] The upper cover material strip unwinding machine, upper cover material strip conveying machine, upper cover cutting machine, upper cover transfer machine, connector body transport machine, laser welding machine and pressure locking machine are all installed on the machine base and arranged in sequence according to the mobile phone connector assembly welding operation process. The operation process is that the upper cover is first cut, then assembled with the connector body, and pressure is applied and welding is completed simultaneously after assembly.

[0010] The top cover material unwinding machine is used for unwinding and feeding the top cover material roll, and its output end is connected to the input end of the top cover material conveyor.

[0011] The cover material conveyor is used to transport the cover material from the unwinding end to the cutting station;

[0012] The upper cover cutting machine is located at the output end of the upper cover material conveyor and is used to cut the upper cover on the upper cover material conveyor into individual parts.

[0013] The cover transfer mechanism is used to transfer the cut individual covers to the connector body carried by the connector body transport mechanism, so as to achieve the initial assembly of the cover and the connector body;

[0014] The connector body transport mechanism is used to carry and position the connector body, and to drive it to move back and forth between the top cover assembly station and the welding station;

[0015] Both the pressure-applying locking mechanism and the laser welding machine are located at the welding station. The pressure-applying locking mechanism is used to apply pressure to the top cover and the connector body after they are assembled, and to keep the top cover under pressure during the welding process of the laser welding machine.

[0016] As a further improvement to the technical solution disclosed in this invention, the mobile phone connector assembly and welding equipment also includes a cover position correction mechanism; the cover position correction mechanism is used to perform position calibration and attitude correction on a single cover after it has been cut by the cover cutting mechanism, and it is arranged downstream of the cover cutting mechanism and upstream of the connector body transport mechanism.

[0017] As a further improvement to the technical solution disclosed in this invention, the cover positioning correction mechanism includes a first support frame, a correction fixture, an X-axis side-push assembly, a Y-axis side-push assembly, a first X-axis spring, a first Y-axis spring, and a first drive unit. The correction fixture is supported by the first support frame and is used to drop the cover to be corrected. The X-axis side-push assembly and the Y-axis side-push assembly are both mounted on the first support frame and are arranged corresponding to the correction fixture. The X-axis side-push assembly and the Y-axis side-push assembly respectively use the spring force provided by the first X-axis spring and the first Y-axis spring to press against the side wall of the cover, thereby jointly achieving its position correction. After the cover is corrected, the first drive unit performs work and applies a reverse force to the X-axis side-push assembly and the Y-axis side-push assembly to move them away from the cover.

[0018] As a further improvement to the technical solution disclosed in this invention, the upper cover position correction mechanism further includes a first X-direction slide rail slider assembly and a Y-direction slide rail slider assembly; the first X-direction slide rail slider assembly and the Y-direction slide rail slider assembly are both installed on the first support frame and are respectively assembled with the X-direction side push assembly and the Y-direction side push assembly; the first X-direction slide rail slider assembly is used to provide guidance for the movement of the X-direction side push assembly along the X direction, and the Y-direction slide rail slider assembly is used to provide guidance for the movement of the Y-direction side push assembly along the Y direction.

[0019] As a further improvement to the technical solution disclosed in this invention, the X-direction side-push assembly includes an X-direction side-push member and a first roller group; the Y-direction side-push assembly includes a Y-direction side-push member and a second roller group; the first drive unit includes a rotary cylinder and a side-push drive disk; the side-push drive disk has a non-circular structure with different radial dimensions at different positions; the rotary cylinder is mounted on a first support frame, and its output shaft is connected to the side-push drive disk; the first roller group is mounted on the X-direction side-push member, and the second roller group is mounted on the Y-direction side-push member; with the help of the elastic force of the first X-direction spring and the first Y-direction spring, the first roller group and the second roller group always maintain a contact state with the side wall of the side-push drive disk; when the side-push drive disk rotates to... When the small radial dimension area contacts the first roller group and the second roller group, the first X-direction spring and the first Y-direction spring release their elastic force, respectively pushing the X-direction side pusher to move synchronously along the X direction and the Y-direction side pusher to move synchronously along the Y direction, so that the X-direction side pusher and the Y-direction side pusher contact the top cover to achieve its position correction; after the top cover is corrected, the side push drive disk continues to rotate, and its large radial dimension area gradually corresponds to the first roller group and the second roller group. At this time, the side push drive disk applies a reverse force to the X-direction side pusher and the Y-direction side pusher through the first roller group and the second roller group, respectively. The X-direction side pusher and the Y-direction side pusher move in opposite directions to move away from the top cover. At the same time, the first X-direction spring and the first Y-direction spring are compressed synchronously.

[0020] As a further improvement to the technical solution disclosed in this invention, the cover transfer mechanism includes a second support frame, a support beam, a first cover picking device, a second cover picking device, a second X-axis slide rail slider assembly, a Z-axis slide rail slider assembly, and a second drive unit; the Z-axis slide rail slider assembly is mounted on the second support frame, and its moving end is connected to the second X-axis slide rail slider assembly; the support beam is installed on the moving end of the second X-axis slide rail slider assembly; the first cover picking device and the second cover picking device are spaced apart and mounted on the support beam; the first cover picking device... The device is used to transfer the top cover from the cutting station to the positioning station. At the same time, the second top cover picking device is used to transfer the aligned top cover from the positioning station to the top cover assembly station. The driving force of the second drive unit acts directly on the load-bearing beam, causing it to move freely relative to the second load-bearing frame in the XZ plane. The distances t1 between the cutting station and the positioning station, t2 between the positioning station and the top cover assembly station, and t3 between the first top cover picking device and the second top cover picking device satisfy t1=t2=t3.

[0021] As a further improvement to the technical solution disclosed in this invention, the second driving unit includes a base plate, a deflector, a third roller assembly, and a reduction motor; the base plate is fixedly mounted on the second support frame and has a nonlinear guide groove on it; the deflector is parallel to the base plate and has a linear guide groove on it; the nonlinear guide groove and the linear guide groove work together to constrain the sliding trajectory of the third roller assembly; the reduction motor is installed on the side of the base plate away from the deflector, and its output shaft passes through the base plate and is connected to the deflector for transmission; one end of the third roller assembly is hinged to the support beam, and the other end is sequentially embedded in the linear guide groove and the nonlinear guide groove; when the reduction motor drives the deflector to rotate circumferentially, the linear guide groove and the nonlinear guide groove work together to drive the third roller assembly to slide along the defined trajectory, thereby pushing the support beam to perform displacement movement relative to the second support frame in the XZ plane, and cooperating with the first and second top cover picking devices to complete the top cover transfer operation.

[0022] As a further improvement to the technical solution disclosed in this invention, the second drive unit further includes a rotation angle sensing unit; the rotation angle sensing unit includes a mounting base, a first position sensor, a second position sensor, a third position sensor, and a sensing disk; the mounting base is fixed to the second support frame, which is used to mount and fix the first position sensor, the second position sensor, and the third position sensor, and the first position sensor, the second position sensor, and the third position sensor are arranged at intervals along the circumference; the sensing disk is driven to the output shaft of the geared motor, and its edge is provided with a sensing structure that is adapted to the first position sensor, the second position sensor, and the third position sensor; when the sensing disk rotates with the output shaft of the geared motor, the sensing structure sequentially triggers the first position sensor, the second position sensor, and the third position sensor to provide real-time feedback on the rotation angle of the geared motor.

[0023] As a further improvement to the technical solution disclosed in this invention, the pressure locking mechanism includes a third support frame, a slide cylinder, a connecting transition plate, a first thin cylinder, a mounting base, a force transmission component, a downward pressure rod assembly, a Z-direction spring, a first side push gripper assembly, a second side push gripper assembly, a second X-direction spring, and a third X-direction spring.

[0024] The slide cylinder is mounted on the third support frame, and its power output end is fixedly connected to the connecting transition plate; the first thin cylinder and the mounting base are both assembled on the connecting transition plate, and the mounting base is located directly below the first thin cylinder; the power output end of the first thin cylinder extends downward in the longitudinal direction and is connected to the force transmission component.

[0025] The mounting base is provided with an assembly structure that allows the first side push gripper assembly and the second side push gripper assembly to slide freely along the X direction; one end of the second X-direction spring abuts against the mounting base and the other end abuts against the first side push gripper assembly; one end of the third X-direction spring abuts against the mounting base and the other end abuts against the second side push gripper assembly, and the second X-direction spring and the third X-direction spring cause the first side push gripper assembly and the second side push gripper assembly to have a tendency to move towards each other along the X direction through elastic force;

[0026] The force transmission component is longitudinally mounted on the mounting base. It has a first side-push inclined surface on the side near the first side-push gripper assembly and a second side-push inclined surface on the side near the second side-push gripper assembly. The first side-push inclined surface is adapted to the force-bearing surface of the first side-push gripper assembly, and the second side-push inclined surface is adapted to the force-bearing surface of the second side-push gripper assembly. When the first thin cylinder drives the force transmission component to move longitudinally, the first side-push inclined surface engages with the force-bearing surface of the first side-push gripper assembly, and the second side-push inclined surface engages with the force-bearing surface of the second side-push gripper assembly, driving the first and second side-push gripper assemblies to separate in opposite directions along the X-direction. When the first thin cylinder drives the force transmission component to reset, the second and third X-direction springs drive the first and second side-push gripper assemblies to approach each other along the X-direction and abut against the connector body.

[0027] The pressure rod assembly is longitudinally inserted into the mounting base and slides with the mounting base; one end of the Z-axis spring abuts against the mounting base and the other end abuts against the pressure rod assembly; when the slide cylinder drives the connecting transition plate to move towards the welding station, the pressure rod assembly contacts the top cover, and under the continuous action of the slide cylinder, the Z-axis spring is compressed and the elastic force keeps the pressure rod assembly pressed against the top cover.

[0028] As a further improvement to the technical solution disclosed in this invention, the connector body carrier mechanism includes:

[0029] The Y-axis linear module installed on the machine tool has a fourth support frame fixed to its moving end, which is used to drive the fourth support frame to reciprocate between the upper cover assembly station and the welding station.

[0030] The loading fixture, the upper cylinder side push assembly, and the lower cylinder side push assembly are assembled on the fourth support frame; the loading fixture is used to support the connector body; the upper cylinder side push assembly and the lower cylinder side push assembly are located on the same side of the loading fixture;

[0031] The connector body Y-direction side pressure member, second Y-direction spring, first upper cover Y-direction side pressure member, second upper cover Y-direction side pressure member, third upper cover Y-direction side pressure member, third Y-direction spring, fourth Y-direction spring, fifth Y-direction spring, first connector body X-direction side pressure member, second connector body X-direction side pressure member, and fourth X-direction spring are assembled on the loading fixture.

[0032] The upper cylinder side push assembly drives the connector body Y-direction side pressure member to contact the connector body along the Y direction, and applies a Y-direction reset force to it by means of the second Y-direction spring; the first upper cover Y-direction side pressure member, the second upper cover Y-direction side pressure member, and the third upper cover Y-direction side pressure member are arranged side by side along the X direction, and are synchronously driven by the lower cylinder side push assembly to contact the upper cover along the Y direction, and the third Y-direction spring, the fourth Y-direction spring, and the fifth Y-direction spring respectively apply a Y-direction reset force to the three of them;

[0033] The first connector body X-direction side pressure member and the second connector body X-direction side pressure member work together to contact the connector body along the X direction, while the fourth X-direction spring applies an X-direction pressing force to the second connector body X-direction side pressure member; the side sliding structure of the second connector body X-direction side pressure member is adapted to the locking groove of the third upper cover Y-direction side pressure member; when the third upper cover Y-direction side pressure member moves along the Y direction, the X-direction displacement of the second connector body X-direction side pressure member is controlled by the cooperation of the side sliding structure and the locking groove.

[0034] In practical applications, the mobile phone connector assembly and welding equipment disclosed in this invention can achieve at least the following beneficial technical effects, specifically:

[0035] 1) By coordinating the top cover material unwinding machine, top cover material conveying machine, top cover cutting machine, and top cover transfer machine with the connector body transport machine, pressure locking machine, and laser welding machine in strict accordance with the sequential operation flow of mobile phone connector assembly and welding, a close-knit transmission and cooperation relationship is formed between the machines, ultimately creating an uninterrupted production flow. Specifically, after the top cover is cut by the top cover cutting machine, it is directly and precisely transferred by the top cover transfer machine to the connector body transport machine to complete the assembly; the assembled semi-finished product is then smoothly transported to the welding station by the connector body transport machine. The continuous operation mode significantly shortens the assembly and welding cycle of a single connector, which can not only meet the needs of the mobile phone mass production line for high-efficiency production cycle, but also avoid the idle situation of single machines, and significantly improve the overall utilization rate of the entire set of equipment.

[0036] 2) In the assembly of the connector body and the top cover, the connector body carrier can not only accurately position the connector body, but also drive it to move smoothly between the top cover assembly station and the welding station, ensuring that the assembly alignment error between the top cover and the body is controlled within the allowable range. In the welding process, the pressure locking mechanism first applies stable pressure to the connector assembly and maintains the pressure state throughout the laser welding machine operation. The synergistic effect of the two can greatly reduce common problems such as poor soldering and misaligned soldering, thereby effectively improving the assembly alignment yield of the top cover and the connector body, while ensuring the consistency of the solder joint quality.

Detailed Implementation

[0069] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2Two perspective views of the mobile phone connector assembly welding equipment disclosed in this invention are shown respectively. It can be seen that the upper cover material unwinding machine 2, the upper cover material conveying machine 3, the upper cover cutting machine 4, the upper cover transfer machine 5, the connector body transport machine 6, the laser welding machine 7, the pressure locking machine 8, and the upper cover position alignment machine 9 are all installed on the machine base 1, and are strictly connected in sequence according to the mobile phone connector assembly welding operation process of "upper cover material unwinding → upper cover material conveying → upper cover cutting → upper cover position alignment → upper cover transfer assembly → electrical connector transport → pressure welding", to ensure that the assembly welding process is continuous and uninterrupted, and to meet the dual requirements of precision and efficiency for mass production.

[0070] The top cover material unwinding machine 2 is used for unwinding and feeding the top cover material roll. Its output end is precisely connected to the input end of the top cover material conveying machine 3, and it has a built-in tension adjustment mechanism. When the tension of the top cover material roll is too high, the tension sensor triggers the unwinding speed to slow down; when the tension is too low, the unwinding speed automatically speeds up, avoiding loosening and wrinkling of the top cover material roll or breakage due to excessive tension, thus providing a stable supply of raw materials for subsequent processes.

[0071] The top cover material conveyor 3 is used to transport the top cover material from the unwinding end to the cutting station, such as... Figure 3 As shown, the cover cutting machine 4 is positioned at the output end of the cover conveyor belt 3 and is used to cut the cover on the cover conveyor belt into individual parts. The cutting blade of the cover cutting machine 4 is made of high-speed steel and the cutting edge is precision ground.

[0072] like Figure 1 As shown, the cover position correction mechanism 9 is used to calibrate and correct the posture of individual covers after they have been cut by the cover cutting mechanism 4. It is located downstream of the cover cutting mechanism 4 and within the picking range of the cover transfer mechanism 5, and is a key step in improving the accuracy of subsequent assembly. Figures 24-27 As shown, the upper cover position correction mechanism 9 is mainly composed of several parts, including a first support frame 91, a correction fixture 92, an X-direction side push assembly 93, a Y-direction side push assembly 94, a first X-direction spring 95, a first Y-direction spring 96, a first drive unit 97, a first X-direction slide rail slider assembly 98, and a Y-direction slide rail slider assembly 99.

[0073] The alignment fixture 92 is supported by the first support frame 91. The X-axis side-push assembly 93 and the Y-axis side-push assembly 94 are both mounted on the first support frame 91 and are symmetrically arranged corresponding to the alignment fixture 92. The X-axis side-push assembly 93 and the Y-axis side-push assembly 94 respectively contact the side wall of the upper cover through the spring force provided by the first X-axis spring 95 and the first Y-axis spring 96, thus jointly achieving position alignment. Figure 28 , Figure 29As shown, the X-direction side push assembly 93 includes an X-direction side push member 931 and a first roller group 932; the Y-direction side push assembly 94 includes a Y-direction side push member 941 and a second roller group 942; the first drive unit 97 includes a rotary cylinder 971 and a side push drive disc 972.

[0074] like Figure 30 As shown, the side-push drive disk 972 has a non-circular structure with different radial dimensions at different positions; the rotary cylinder 971 is mounted on the first support frame 91, and its output shaft is connected to the side-push drive disk 972; the first roller group 932 is assembled on the X-direction side-push member 931, and the second roller group 942 is assembled on the Y-direction side-push member 941; with the help of the elastic force of the first X-direction spring 95 and the first Y-direction spring 96, the first roller group 932 and the second roller group 942 always maintain a contact state with the side wall of the side-push drive disk 972, ensuring that the X-direction side-push assembly 93 and the Y-direction side-push assembly 94 respond promptly.

[0075] The first X-axis slide rail slider assembly 98 and the Y-axis slide rail slider assembly 99 are both mounted on the first support frame 91 and are respectively assembled with the X-axis side push assembly 93 and the Y-axis side push assembly 94 to provide precise guidance for movement, avoid deviation during side push, and ensure alignment accuracy. When the side push drive disk 972 rotates to the small radial dimension area and contacts the first roller group 932 and the second roller group 942, the first X-axis spring 95 and the first Y-axis spring 96 release their elastic force, pushing the X-axis side push member 931 to move synchronously along the X direction and the Y-axis side push member 941 to move synchronously along the Y direction, so that the side push member contacts the upper cover and pushes it to the center position of the fixture cavity, realizing position alignment; after the upper cover position is aligned, the side push drive disk 972 continues to rotate, and its large radial dimension As the size area gradually aligns with the first roller group 932 and the second roller group 942, the side push drive disk 972 applies reverse forces to the X-direction side push member 931 and the Y-direction side push member 941 via the first roller group 932 and the second roller group 942, respectively. The X-direction side push member 931 and the Y-direction side push member 941 can move in opposite directions to move away from the top cover. At the same time, the first X-direction spring 95 and the first Y-direction spring 96 are compressed synchronously so that the top cover transfer mechanism 5 can pick them up.

[0076] The top cover transfer mechanism 5 is used to transfer the aligned individual top covers to the connector body carried by the connector body transport mechanism 6, thus achieving initial assembly of the top cover and the connector body. For example... Figure 4 , Figure 5 As shown, the cover transfer mechanism 5 mainly consists of several parts, including a second support frame 51, a support beam 52, a first cover picking device 53, a second cover picking device 54, a second X-axis slide rail slider assembly 55, a Z-axis slide rail slider assembly 56, and a second drive unit 57.

[0077] Z-axis slide rail slider assembly 56 is assembled on the second support frame 51, and its moving end is connected to the second X-axis slide rail slider assembly 55; the support beam 52 is installed on the moving end of the second X-axis slide rail slider assembly 55. The first top cover picking device 53 and the second top cover picking device 54 are spaced apart and assembled on the support beam 52, both of which adopt a vacuum adsorption structure.

[0078] The first cover picking device 53 is used to transfer the cover from the position correction station to the cover assembly station. At the same time, the second cover picking device 54 is used to transfer the newly cut and corrected cover from the correction station to the temporary storage station (synchronously connected with the assembly station), realizing the synchronous operation of "one pick and one place". Moreover, the distance t1 between the cutting station and the position correction station, the distance t2 between the position correction station and the cover assembly station, and the distance t3 between the first cover picking device 53 and the second cover picking device 54 satisfy t1=t2=t3, ensuring that the load-bearing beam 52 can complete the transfer of the cover between the two stations in a single movement, greatly improving the transfer efficiency.

[0079] The driving force of the second drive unit 57 acts directly on the load-bearing crossbeam 52, causing it to move freely relative to the second load-bearing frame 51 in the XZ plane. For example... Figure 6 , Figure 7 As shown, the second drive unit 57 includes a base plate 571, a deflector 572, a third roller assembly 573, and a reduction motor 574. The base plate 571 is fixedly mounted on the second support frame 51 and has a nonlinear guide groove 5711. The deflector 572 is parallel to the base plate 571 and has a linear guide groove 5721. The nonlinear guide groove 5711 and the linear guide groove 5721 work together to constrain the sliding trajectory of the third roller assembly 573 and ensure that the support beam 52 moves along a preset path.

[0080] The geared motor 574 is mounted on the side of the base plate 571 opposite to the deflector 572. Its output shaft passes through the base plate 571 and is connected to the deflector 572 for transmission. The geared motor 574 is equipped with a planetary gear reducer to ensure stable output torque and avoid jamming during movement. One end of the third roller assembly 573 is hinged to the load-bearing crossbeam 52, and the other end is sequentially embedded in the linear guide groove 5721 and the nonlinear guide groove 5711 (e.g., ...). Figure 8 , Figure 9 (As shown in the figure); when the geared motor 574 drives the oscillating component 572 to rotate circumferentially, the linear guide groove 5721 and the nonlinear guide groove 5711 cooperate to drive the third roller assembly 573 to slide along the limited trajectory, thereby pushing the load-bearing beam 52 to perform displacement movement in the XZ plane, and cooperate with the picking device to complete the transfer of the upper cover.

[0081] like Figures 7-9As shown, the second drive unit 57 also includes a rotation angle sensing unit 575. The rotation angle sensing unit 575 mainly consists of a mounting base plate 5751, a first position sensor 5752, a second position sensor 5753, a third position sensor 5754, and a sensing disk 5755. The mounting base plate 5751 is fixed to the second support frame 51 and is used to mount and fix the first position sensor 5752, the second position sensor 5753, and the third position sensor 5754, which are arranged at circumferential intervals. The sensing disk 5755 is driven by the output shaft of the reduction motor 574, and its edge is provided with a metal sensing plate adapted to the sensor. When the sensing disk 5755 rotates with the output shaft, the sensing plate sequentially triggers the first position sensor 5752, the second position sensor 5753, and the third position sensor 5754, providing real-time feedback on the rotation angle of the reduction motor 574, thereby accurately controlling the displacement distance of the support beam 52 and avoiding positional deviation during the transfer of the upper cover.

[0082] The connector body transport mechanism 6 is used to carry and position the connector body, and to drive it to reciprocate between the top cover assembly station and the soldering station. For example... Figures 10-15 As shown, the connector body transport mechanism 6 mainly consists of several parts, including a Y-axis linear module 61, a fourth support frame 62, a loading fixture 63, an upper cylinder side push assembly 64, a lower cylinder side push assembly 65, a connector body Y-axis side pressure member 66, a second Y-axis spring 67, a first upper cover Y-axis side pressure member 68, a second upper cover Y-axis side pressure member 69, a third upper cover Y-axis side pressure member 610, a third Y-axis spring 611, a fourth Y-axis spring 612, a fifth Y-axis spring 613, a first connector body X-axis side pressure member 614, a second connector body X-axis side pressure member 615, and a fourth X-axis spring 616.

[0083] The Y-axis linear module 61 is mounted on machine base 1, and its moving end is fixedly connected to the fourth support frame 62, which is used to drive the fourth support frame 62 to reciprocate between the upper cover assembly station and the welding station. The Y-axis linear module 61 is driven by a servo motor and a ball screw transmission structure to ensure smooth movement and provide a guarantee for the accuracy of subsequent assembly and welding. The loading fixture 63, the upper cylinder side push assembly 64, and the lower cylinder side push assembly 65 are all assembled on the fourth support frame 62. The loading fixture 63 is used to support the connector body, and its internal positioning groove is perfectly matched with the shape of the connector body to prevent displacement during movement.

[0084] The upper cylinder side-push assembly 64 and the lower cylinder side-push assembly 65 are located on the same side of the loading fixture 63 and are used to drive the connector body and the upper cover to be side-pressed and positioned, respectively. The connector body Y-direction side-pressing member 66, the second Y-direction spring 67, the first upper cover Y-direction side-pressing member 68, the second upper cover Y-direction side-pressing member 69, the third upper cover Y-direction side-pressing member 610, the third Y-direction spring 611, the fourth Y-direction spring 612, the fifth Y-direction spring 613, the first connector body X-direction side-pressing member 614, the second connector body X-direction side-pressing member 615, and the fourth X-direction spring 616 are all assembled on the loading fixture 63.

[0085] The upper cylinder side push assembly 64 drives the connector body Y-direction side pressure member 66 to contact the connector body along the Y direction, and applies a Y-direction reset force to it by means of the second Y-direction spring 67 to ensure that the connector body is stably positioned in the Y direction; the first upper cover Y-direction side pressure member 68, the second upper cover Y-direction side pressure member 69, and the third upper cover Y-direction side pressure member 610 are arranged side by side along the X direction, and are synchronously driven by the lower cylinder side push assembly 65 to contact the upper cover along the Y direction. The third Y-direction spring 611, the fourth Y-direction spring 612, and the fifth Y-direction spring 613 apply a Y-direction reset force to the three respectively to achieve precise positioning of the upper cover in the Y direction.

[0086] The first connector body X-direction side pressure member 614 and the second connector body X-direction side pressure member 615 cooperate to contact the connector body along the X direction. The fourth X-direction spring 616 applies an X-direction clamping force to the second connector body X-direction side pressure member 615 to ensure the positioning stability of the connector body in the X direction. Figure 16 , Figure 17 As shown, the sliding structure 6151 of the X-direction side pressure member 615 of the second connector body is adapted to the locking groove 6101 of the Y-direction side pressure member 610 of the third upper cover; when the Y-direction side pressure member 610 of the third upper cover moves along the Y direction, the sliding structure 6151 slides along the inclined surface of the locking groove 6101, driving the X-direction side pressure member 615 of the second connector body to move synchronously along the X direction, realizing the linkage and coordination of the positioning of the connector body and the upper cover, and further reducing the assembly alignment error between the two.

[0087] Both the pressure-applying locking mechanism 8 and the laser welding machine 7 are positioned at the welding station. The pressure-applying locking mechanism 8 applies pressure to the top cover and connector body after they are assembled, and maintains the pressure on the top cover during the welding process of the laser welding machine 7, preventing weld point misalignment or incomplete welding due to loosening of components during the welding process. Figure 18 , Figure 19 As shown, the pressure-locking mechanism 8 mainly consists of several parts, including a third support frame 81, a slide cylinder 82, a connecting transition plate 83, a first thin cylinder 84, a mounting base 85, a force transmission component 86, a downward pressure rod assembly 87, a Z-direction spring 88, a first side push gripper assembly 89, a second side push gripper assembly 810, a second X-direction spring 811, and a third X-direction spring 812.

[0088] like Figures 20-22 As shown, the slide cylinder 82 is mounted on the third support frame 81, and its power output end is fixedly connected to the connecting transition plate 83. It is used to drive the connecting transition plate 83 to move the subsequent components closer to or away from the welding station. The stroke accuracy of the slide cylinder 82 is controlled within ±0.02mm to ensure accurate pressure application. The first thin cylinder 84 and the mounting base 85 are both mounted on the connecting transition plate 83, and the mounting base 85 is located directly below the first thin cylinder 84. The power output end of the first thin cylinder 84 extends downward longitudinally and is connected to the force transmission component 86. Its output pressure can be adjusted by the pressure regulating valve to avoid excessive pressure damaging the components.

[0089] Mounting base 85 is provided with a sliding groove for the first side-push gripper assembly 89 and the second side-push gripper assembly 810 to slide freely in the X direction; one end of the second X-direction spring 811 abuts against the mounting base 85 and the other end abuts against the first side-push gripper assembly 89; one end of the third X-direction spring 812 abuts against the mounting base 85 and the other end abuts against the second side-push gripper assembly 810, and the elastic coefficients of the second X-direction spring 811 and the third X-direction spring 812 are the same. Through the elastic force, the two gripper assemblies have a tendency to move towards each other in the X direction, ensuring uniform clamping force.

[0090] The force transmission component 86 is longitudinally inserted into the mounting base 85. A first side-pushing inclined surface 861 is provided on the side near the first side-pushing jaw assembly 89, and a second side-pushing inclined surface 862 is provided on the side near the second side-pushing jaw assembly 810 (e.g., ...). Figure 23 (As shown in the diagram). The first side push slope 861 is adapted to the force-bearing surface of the first side push gripper assembly 89, and the second side push slope 862 is adapted to the force-bearing surface of the second side push gripper assembly 810. When the first thin cylinder 84 drives the force transmission component 86 to move longitudinally downward, the first side push slope 861 and the second side push slope 862 respectively cooperate with the force-bearing surfaces of the first side push gripper assembly 89 and the second side push gripper assembly 810, converting the longitudinal force into a transverse force, driving the first side push gripper assembly 89 and the second side push gripper assembly 810 to separate in the opposite direction along the X direction, so that the connector body transport mechanism 6 can send the assembly to the welding station. When the first thin cylinder 84 drives the force transmission component 86 to reset upward, the second X-direction spring 811 and the third X-direction spring 812 release their elastic force, driving the first side push gripper assembly 89 and the second side push gripper assembly 810 to move towards each other along the X direction and press against the connector body, ensuring that the body is stable and does not shift.

[0091] like Figures 19-21As shown, the pressure rod assembly 87 is longitudinally inserted into the mounting base 85 with a clearance fit to ensure smooth and unobstructed longitudinal sliding. A polyurethane buffer pad is provided on the lower end face of the pressure rod assembly 87, which is fixed by adhesive bonding. This prevents surface scratches caused by hard contact between the pressure rod assembly 87 and the upper cover, and also allows for uniform pressure transmission through its own deformation. One end of the Z-axis spring 88 abuts against the lower end face step of the mounting base 85, while the other end elastically contacts the pressure rod assembly 87.

[0092] When the slide cylinder 82 moves the connecting transition plate 83 towards the welding station, the buffer pad at the lower end of the pressure rod assembly 87 first contacts the surface of the upper cover. As the slide cylinder 82 continues to descend, the Z-axis spring 88 is further compressed, and the resulting elastic force is transmitted to the upper cover through the pressure rod assembly 87, making the upper cover and the connector body fit tightly together. After the laser welding machine 7 starts welding, the elastic force of the Z-axis spring 88 can compensate for the slight displacement of the upper cover and the body caused by the welding heat deformation in real time, always keeping the upper cover under pressure and avoiding gaps in the welding area that could lead to incomplete welds.

[0093] After the laser welding machine 7 completes the welding operation, the first thin cylinder 84 drives the force transmission component 86 to move downward, causing the first side push gripper assembly 89 and the second side push gripper assembly 810 to separate in the opposite direction along the X direction; then the slide cylinder 82 drives the connecting transition plate 83 to reset upward, and the lower pressure rod assembly 87 moves upward and separates from the upper cover; after the connector body transport mechanism 6 moves the welded connector out of the welding station, the pressure locking mechanism 8 returns to its initial state, waiting for the next assembly to enter, achieving seamless connection with the subsequent process.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
